Review on research development and clinical application of terminal traction and exoskeleton upper limb rehabilitation robots SHI Weiwei, JIN Lingjing Surgical Research and New Technique    2025, 14 (2): 101-106.   DOI: 10.3969/j.issn.2095-378X.2025.02.001 Abstract （676）      PDF（pc） （619KB）（2070）       Knowledge map    With the aggravation of global aging and the increase of incidence rate of stroke, traumatic brain injury, and other neurological diseases, the need for upper limb rehabilitation is increasingly urgent. Traditional rehabilitation methods are limited by the shortage of therapist resources and the difficulty in quantifying treatment intensity and effectiveness. However, upper limb rehabilitation robots provide a new direction to solve these problems. This article systematically reviewed the research progress and clinical application status of terminal traction and exoskeleton upper limb rehabilitation robots. Through in-depth analysis of relevant literature, the technical characteristics, clinical efficacy, and application scenarios of these two types of robots were summarized. Research has found that upper limb rehabilitation robots have shown positive potential in improving limb function and enhancing daily living activities in patients with upper limb motor dysfunction, and have achieved certain results in both short-term and long-term rehabilitation treatments, but there is still a lack of large-scale, long-term research data support to compare with traditional rehabilitation methods. At present, this field is facing challenges such as high equipment costs, complex operations, and insufficient clinical validation. In the future, there is an urgent need to enhance the intelligence, adaptability, and cost-effectiveness of rehabilitation robots through the integration of artificial intelligence, biomechanics, and sensor technology, and to develop user-friendly products that better meet the needs of patients. This will promote the widespread application of rehabilitation robots in clinical practice and effectively improve the quality of life of patients with upper limb dysfunction.

Risk factors for hypocalcemia after thyroid nodule resection HUO Jianting, HUO Huanmin, DING Min, XIE Rongli, SHEN Dongjie, FEI Jian Surgical Research and New Technique    2025, 14 (3): 211-215.   DOI: 10.3969/j.issn.2095-378X.2025.03.003 Abstract （409）      PDF（pc） （1334KB）（251）       Knowledge map    Objective To study the risk factors of postoperative hypocalcemia after resection of thyroid nodules. Methods A retrospective study was conducted on 124 patients undergoing thyroid nodule resection surgery, including age, gender, mass nature, lesion location （unilateral/bilateral）, lymph node dissection, surgical approach, perioperative blood calcium （adjusted and un-adjusted）, parathyroid hormone （PTH）, and blood magnesium. Patients were divided into a hypocalcemia group and a non-hypocalcemia group based on their postoperative blood calcium levels, to compare the differences between the two groups and thereby investigate the risk factors for hypocalcemia after thyroid nodule resection. Results Of the 124 cases enrolled, 12 cases （9.7%） developed hypocalcemia after the operation, with an average blood calcium of （2.10±0.08） mmol/L. After albumin correction of blood calcium level, 9 cases （7.3%） had hypocalcemia, with an average blood calcium of （2.05±0.14） mmol/L. There were no statistically significant differences between the two groups stratified by corrected blood calcium levels in terms of age, gender, mass nature, and performance of lymph node dissection （P> 0.05）. However, significant differences were observed in lesion location （unilateral/bilateral）, surgical approach, average postoperative PTH level, and presence of postoperative hypomagnesemia （P<0.05）. Conclusion For patients with postoperative hypoproteinemia, corrected blood calcium levels should be used to evaluate whether the patient needs additional calcium supplementation. Surgical procedure is a high-risk factor for postoperative hypocalcemia, and postoperative hypomagnesemia and postoperative PTH reduction are associated with hypocalcemia.

Methods This study selected 800 patients who received painless gastroscopy in our hospital from February 2024 to December 2024. They were randomly divided into a control group and groups A1, A2, and A3, with 200 patients in each group. The control group patients were induced with remimazolam anesthesia （0.3 mg/kg）, Groups A1, A2, and A3 were induced with 0.20, 0.25, and 0.30 mg/kg ciprofol combined with 0.15 mg/kg remimazolam anethesia. Comparisons were conducted on the anesthesia induction time, gastrointestinal endoscopy duration, awakening time, directional force recovery time, heart rate, blood pressure, blood oxygen saturation, and incidence of adverse reactions. Results The success rate of sedation in Group A2 was significantly higher than that in the control group and Group A1 （P<0.05）, and there was no significant difference compared to Group A3 （P>0.05）. The duration of gastrointestinal endoscopy in Group A2 was significantly shorter than that in the control group and Group A1 （P<0.05）, and there was no significant difference compared to Group A3 （P>0.05）. The awakening time and directional force recovery time in Group A2 were significantly shorter than those in the control group and Group A3 （P<0.05）, and there was no significant difference compared to Group A1 （P<0.05）. The heart rates at loss of ciliary reflex after induction of anesthesia （T1） and at the begining of gastrointestinal endoscopy （T2） of the four groups of patients were all significantly reduced compared to 5 min before pre-anethesia （T0） （P<0.05）, and the decrease in heart rate in Group A2 was significantly lower than those in the control group, Group A1, and Group A3 （P<0.05）. The heart rate in Group A3 at the end of surgery （T3） was significantly lower than those in the control group, Group A1, and Group A2 （P<0.05）, while there was no significant difference between the control group, Group A1, and Group A2 （P>0.05）. The blood pressure values at T1 and T2 of the four groups of patients were significantly lower than those at T0 （P<0.05）, and the decrease in blood pressure in Group A2 was significantly lower than those in Groups A1 and A3 （P<0.05）. The blood pressure in Group A3 at T3 was significantly lower than those in the control group, Group A1, and Group A2 （P<0.05）, and there was no significant difference between the control group, Group A1, and Group A2 （P>0.05）. The blood oxygen saturation levels at T1 and T2 of the four groups of patients were significantly reduced compared to T0 （P<0.05）. The decrease in blood oxygen saturation level in Group A3 was significantly higher than those in the control group, Group A1, and Group A2 （P<0.05）. The blood oxygen saturation level at T3 in Group A3 was significantly lower than those in the control group, Group A1, and Group A2 （P<0.05）, while there was no significant difference between the control group, Group A1, and Group A2 （P>0.05）. The incidence of adverse reactions in Group A2 （10.00%） was significantly lower than those in the control group （21.00%）, Group A1 （12.00%）, and Group A3 （13.00%） （χ2=11.408, P<0.05）. Conclusion The combination of 0.25 mg/kg ciprofol and 0.15 mg/kg remimazolam in painless gastroscopy can exert the same sedative effect of ciprofol at high doses, which is beneficial for maintaining stable vital signs of patients without causing significant impact on their breathing, while reducing the occurrence of adverse reactions.

Mechanical removal of deep vein thrombosis of lower extremity： Development, controversy, and future prospects WANG Xuhui, ZUO Liang, YIN Minyi Surgical Research and New Technique    2025, 14 (3): 199-203.   DOI: 10.3969/j.issn.2095-378X.2025.03.001 Abstract （352）      PDF（pc） （1272KB）（168）       Knowledge map    Deep vein thrombosis （DVT） of the lower extremity is a common and serious condition in vascular surgery, and can lead to fatal pulmonary embolism （PE） and post-thrombotic syndrome （PTS）, severely affecting quality of life. Although traditional anticoagulation therapy serves as the cornerstone, it has limited efficacy in removing established thrombi. Consequently, the incidence of PTS remains persistently high （20%‒50%）. Furthermore, for patients with extensive iliofemoral vein thrombosis （e.g., phlegmasia cerulea dolens）, anticoagulation alone is insufficient to prevent high-risk limb gangrene. Catheter-directed thrombolysis （CDT） has shown promise, but pivotal studies （e.g., the ATTRACT trial） have demonstrated that it fails to significantly reduce the incidence of long-term PTS and increases the risk of bleeding. Percutaneous mechanical thrombectomy （PMT）, as an innovative physical thrombectomy technology, has developed rapidly over the past decade. New and efficient devices have emerged and have been recommended by domestic and international guidelines. Based on the background, core advantages, and guideline positioning of PMT technology, this paper systematically reviewed the technical principles, clinical evidence, and safety characteristics of mainstream PMT devices. It analyzed the key challenges currently faced, focused on their future development prospects, and proposed directions that need to be urgently addressed, such as intelligent precision, efficiency improvement, cost control, and high-quality evidence-based research.

Risk factors for recurrence of intracranial aneurysms after interventional treatment WANG Jue, WEI Jianbo Surgical Research and New Technique    2025, 14 (2): 153-156.   DOI: 10.3969/j.issn.2095-378X.2025.02.012 Abstract （341）      PDF（pc） （1884KB）（206）       Knowledge map    Objective To analyze the risk factors for recurrence of intracranial aneurysms after interventional treatment. Methods Forty patients with intracranial aneurysms admitted to our hospital from June 2021 to June 2023 were selected as study subjects. All patients underwent interventional treatment and were followed up for one year after surgery. Arterial angiography was performed 6 months postoperatively and again one year later to check for recurrence. The patients were divided into a recurrence group （11 cases） and a non-recurrence group （29 cases） based on whether the aneurysm had recurred. The aneurysm location, aneurysm diameter, aneurysm neck classification, Raymond grading, smoking and alcohol consumption after treatment were compared between the two groups. Multivariate logistic regression analysis was used to identify the risk factors for recurrence of intracranial aneurysms after interventional treatment, and corresponding prevention strategies were formulated. Results There was no statistically significant difference in the location of aneurysms between the recurrence group and the non-recurrence group （P>0.05）. The recurrence group had higher incidence rates of aneurysms with a diameter of 5-6 mm, a wide neck type, and class Ⅱ-Ⅲ by Raymond grading, and smoking and alcohol consumption rates after treatment compared to the non-recurrence group （P<0.05）.The multivariate logistic regression analysis showed that aneurysm diameter, aneurysm neck classification, Raymond grading, smoking, and alcohol consumption were independent risk factors for recurrence of intracranial aneurysms after interventional treatment. Conclusion The risk factors for recurrence of intracranial aneurysms after interventional treatment include aneurysm diameter, aneurysm neck classification, Raymond grading, smoking, and alcohol consumption. It is recommended that patients with large aneurysm diameter, wide aneurysm neck classification, and high Raymond grading undergo regular postoperative follow-up and early intervention. In addition, it is recommended that patients avoid smoking and alcohol consumption after surgery to reduce the risk of disease recurrence. Reference | Related Articles | Metrics

Methods A total of 100 PHN patients treated from January 2022 to December 2024 were selected as research subjects and randomly divided into a nerve block group （paravertebral nerve block） and a combined treatment group （paravertebral nerve block combined with pulsed radiofrequency）, with 50 cases in each group. The effects between the two groups were compared. Results Before treatment, there was no significant difference in visual analog scale （VAS）, pain rating index （PRI）, and present pain intensity （PPI） scores between the two groups （P>0.05）. The VAS, PRI, and PPI scores of both groups were significantly reduced after treatment （7 d and 30 d） （P<0.05）, and the scores in the combined treatment group were lower than those in the nerve block group （P<0.05）. Before treatment, there were no significant differences in self-rating anxiety scale （SAS）, self-rating depression scale （SDS）, Pittsburgh sleep quality index （PSQI）, and short-form 36 （SF-36） scores between the two groups （P>0.05）. At 30 d after treatment, the SAS, SDS, PSQI, and SF-36 scores of the two groups were significantly improved （SAS, SDS, and PSQI scores were reduced, while SF-36 scores were imcreased） （P<0.05）, and the scores in the combined treatment group were significantly better than those in the nerve block group （P<0.05）. The total effective rate of treatment of the combined treatment group was significantly higher than that of the nerve block group （P<0.05）. Conclusion Nerve block combined with pulse radiofrequency in the treatment of PHN can significantly alleviate pain of patients and improve treatment efficacy, which meets clinical needs and can be popularized.

Methods Sixty stroke patients with hemiplegia and spasticity in the lower limbs （research group） and 60 healthy volunteers （control group） who were treated at Shanghai Ruijin Rehabiliation Hospital from January 2023 to December 2024 were enrolled in the study. The Young’s modulus （YM） values of gastrocnemius muscle in the control group and the research group before and after rehabilitation treatment were measured by SWE, and the lower limb muscle strength of the research group before and after rehabilitation was evaluated by modified Ashworth scale （MAS）. After treatment, the research group was divided into a predictive operation group （the YM values of the affected side >50% of the healthy side, and secondary intervention was required） and a conservative treatment group （no secondary intervention was required） according to the changes of gastrocnemius muscle YM values before and after treatment to compare the YM values before treatment. Results In the research group, the YM value of the gastrocnemius muscle was significantly decreased after treatment [（63.45±19.92） kPa vs （48.32±19.83） kPa, P<0.05], and the MAS score was significantly improved [（2.35±1.02） vs （1.50±1.23）, P<0.05]. There was a positive correlation between YM and MAS scores （r=0.630, P<0.05）. Subgroup analysis showed that the predictive operation group （22 cases） had a significantly higher YM value than the conservative treatment group [（78.35±14.18） kPa vs（46.19±18.40） kPa, P<0.05]. Conclusion SWE can quantitatively analyze the rehabilitation effect of post-stroke spasticity of lower limbs and predict the demand for treatment （High YM value is potentially associated with the demand for surgical treatment）, which provides objective and powerful evidence for clinical treatment.

Methods In this study, 75 patients with rotator cuff injury complicated with LHBT rupture who received compression screw fixation from November 2021 to November 2023 were selected as the screw group, and another 75 patients with rotator cuff injury complicated with LHBT rupture who received wire anchor binding and fixation at the same time period were selected as the anchor group. The clinical data of the two groups were retrospectively analyzed. Results There were no significant differences in visual analog scale （VAS） scores, University of California at Los Angeles Shoulder Rating Scale （UCLA） scores, American Shoulder and Elbow Surgeon’s Form （ASES） scores, and shoulder joint motion between the two groups before surgery （P>0.05）. The VAS, UCLA, and ASES scores and shoulder joint motion between the two groups at all time points （3, 6, and 12 months） were significantly higher than those before surgery （P<0.05）. The VAS scores of the screw group at 3 months and 6 months after surgery were significantly lower than those of the anchor group （P<0.05）, and there was no significant difference in VAS score between the two groups at 12 months after surgery （P>0.05）. There were no significant differences in UCLA and ASES scores and shoulder joint motion between the two groups at each time point after surgery （P>0.05）. The complication rate of the screw group was significantly higher than that of the anchor group （P<0.05）, and there was no significant difference in reoperation rate between the two groups （P>0.05）. Conclusion Both fixation methods have good therapeutic effects. Compression screw fixation can better control the early postoperative pain of patients, and wire anchor binding and fixation can effectively reduce the occurrence of postoperative complications, so the clinical selection should be based on the specific situation.

Clinicopathological features, treatment regimens, and efficacy analysis of 217 cases of epulis LIN Liangqin, LIN Pingting Surgical Research and New Technique    2025, 14 (3): 221-225.   DOI: 10.3969/j.issn.2095-378X.2025.03.005 Abstract （280）      PDF（pc） （1392KB）（1181）       Knowledge map    Objective To investigate the clinicopathological features of epulis and its histopathological subtypes and evaluate the outcomes of different excision methods （scalpel, electrotome, or laser） on the prognosis of epulis. Methods A total of 217 cases of epulis were retrospectively analyzed between August 2021 to July 2024. Gender, age, tumor location, size, symptoms of periodontitis at first visit, excision method, tooth extraction, and root planning during surgery were derived from medical records. Recurrence information was used to evaluate outcomes of different treatment regimens. Results The average age of the patients in this study was （40.25±11.32） years, with a common age range of 20‒40 years. Among them, 134 （61.75%） were female patients and 83 （38.25%）were male patients; epulis was significantly more common in females （χ2=11.986, P<0.001）. There were 130 cases （59.91%） of epulis located in the anterior tooth area and 87 cases （40.09%） in the posterior tooth area, and the proportion of anterior tooth area was significantly higher than that of posterior tooth area for epulis （χ2=10.594, P=0.014）. Histopathologically, the incidence rate from high to low was epulis fibromatosa （69.59%）, epulis granulomatosa （21.20%）, peripheral ossifying fibroma （8.29%）, and giant cell epulis （0.92%）. From the perspective of recurrence, the method of epulis resection, whether the affected tooth was removed, and whether there was periodontitis before surgery had no significant effects on recurrence （P>0.05）. However, the patients receiving root planing during surgery had a significantly lower incidence of recurrence than those who did not （χ2=7.814, P=0.018）. Conclusion Epulis is common in women and in the anterior tooth area, and fibrous hyperplasia is dominant in histopathological subtypes. When concerning treatment regimens, removal methods and tooth extraction would not interfere with recurrence. Root planing during surgery might help reduce the recurrence of epulis.

Methods A total of 100 patients who underwent painless gastrointestinal endoscopy at the First Hospital of Danjiangkou City, Hubei Province were randomly selected from January 2023 to January 2025. According to anesthesia regimens, they were divided into two groups, with 50 cases in each group. The control group was given intravenous anesthesia with propofol combined with alfentanil, while the observation group was administered intravenous anesthesia with remimazolam combined with alfentanil. The vital signs [systolic blood pressure （SBP）, diastolic blood pressure （DBP）, heart rate （HR）, and blood oxygen saturation （SpO2）], clinical indicators （anesthesia induction time, examination time, and awakening time）, and adverse reactions were compared between the two groups. Results After implementing different intravenous anesthesia regimens, the SBP, DBP, and HR values at 5 min of examination （T2） and at the end of examination （T3）, as well as the SpO2 at T2, were more stable in the observation group than those in the control group. The anesthesia induction time, examination time, and awakening time were shorter, and the overall incidence of adverse reactions was lower in the observation group than in the control group （P<0.05）. Conclusion For painless gastrointestinal endoscopy, the use of remimazolam combined with alfentanil for intravenous anesthesia has a high application value and is worth promoting.

Impact of perioperative respiratory guidance on lung function and complications in patients undergoing thoracoscopic lung cancer resection CHEN Fangshuo, CHEN Jianming Surgical Research and New Technique    2025, 14 (3): 248-252.   DOI: 10.3969/j.issn.2095-378X.2025.03.011 Abstract （262）      PDF（pc） （1353KB）（256）       Knowledge map    Objective To investigate the effect of perioperative respiratory guidance on lung function and complications in patients undergoing thoracoscopic lung cancer resection. Methods This study selected 80 perioperative patients undergoing thoracoscopic lung cancer resection from February 2021 to July 2024. The study subjects were divided into a control group and an observation group using a random number table method, with 40 cases in each group. The control group received routine nursing interventions, while the observation group received respiratory guidance on the basis of the control group. Lung function indicators after invervention, postoperative recovery indicators, and incidence of complications were compared between the two groups. Results Before intervention, there was no significant difference in pulmonary function indexes [forced expiratory volume in 1 s （FEV1）, vital capacity （VC）, and forced vital capacity （FVC）] between the two groups. After intervention, the lung function indicators of the observation group were significantly higher than those of the control group （P<0.05）. The observation group had significantly lower postoperative exhaust time and initial out-of-bed time than the control group （P<0.05）. The incidence of complications in the observation group was only 7.50%, lower than 32.50% in the control group （χ2=7.813,P<0.05）. Conclusion Respiratory guidance during the perioperative period for patients undergoing thoracoscopic lung cancer resection can improve their lung function while reducing the incidence of complications, which has clinical significance.

A dose-response relationship study of oliceridine combined with propofol for gastrointestinal endoscopy HUANG Guangyong, HUANG Minzhen, LIU Baoyun Surgical Research and New Technique    2025, 14 (3): 230-233.   DOI: 10.3969/j.issn.2095-378X.2025.03.007 Abstract （261）      PDF（pc） （1371KB）（242）       Knowledge map    Objective To determine the median effective dose （ED50） and 95% effective dose （ED95） of oliceridine combined with propofol （plasma target-controlled concentration at 3 μg/mL） for painless gastrointestinal endoscopy. Methods A total of 27 patients scheduled for painless gastrointestinal endoscopy from July to December 2024 were enrolled. All patients received propofol via target-controlled infusion （TCI） at a plasma concentration of 3 μg/mL. The modified Dixon's up-and-down sequential method was used to determine the oliceridine dose （initial dose 1 mg,step size 0.1 mg）. The dose for each subsequent patient was adjusted based on the response of the previous patient （positive response： coughing, retching, or purposeful movement during endoscopy）, with an increase after a positive response and a decrease after a negative response. The study was terminated after 7 response crossovers. Probit regression analysis was used to calculate the ED50, ED95, and their 95% confidence intervals （CIs） for oliceridine. Results The ED50 of oliceridine combined with propofol （TCI 3 μg/mL） for gastrointestinal endoscopy was 0.829 mg （95%CI 0.509-1.053 mg）, and the ED95 was 1.176 mg （95%CI 0.997-4.936 mg）. Conclusion When oliceridine is combined with propofol （TCI 3 μg/mL） for gastrointestinal endoscopy, the ED95 of oliceridine to suppress the insertion response is 1.176 mg. This provides a dose reference for clinical application. Reference | Related Articles | Metrics

Efficacy of minimally invasive arthroscopic Kirschner wire tension banding in treatment of patella fracture and factors associated with postoperative complications LIU Haixin, LU Jianqi, CAI Zhongbin, WANG Quan, WANG Zemin, WANG Haiwen, XU Xianglin, LU Jiongwen Surgical Research and New Technique    2025, 14 (3): 238-242.   DOI: 10.3969/j.issn.2095-378X.2025.03.009 Abstract （257）      PDF（pc） （7508KB）（109）       Knowledge map    Objective To investigate the efficacy of minimally invasive Kirschner wire tension band internal fixation under arthroscopy for the treatment of patellar fractures and analyze the factors related to postoperative complications. Methods Sixty patients with patellar fractures treated in the Orthopedic Department from January 2021 to January 2025 were selected as research subjects. The patients were randomly divided into a control group and a study group, with 30 cases in each group. The control group received open reduction and Kirschner wire tension band internal fixation treatment, while the study group received minimally invasive Kirschner wire tension band internal fixation treatment under arthroscopy. Fracture healing time, knee joint range of motion, knee joint function （Bostman score）, daily living ability （Barthel index, BI）, quality of life （life satisfaction index A scale, LISA）, pain score （visual analog scale, VAS）, and postoperative complications were compared between the two groups after treatment. Univariate and multivariate logistic regression analyses were conducted on factors related to the complications. Results After treatment, the fracture healing time of the study group was significantly shorter than that of the control group, and the improvement of knee joint range of motion and knee joint function was better than that of the control group （P<0.05）. After treatment, the BI and LISA scores of the study group were significantly higher than those of the control group, and the VAS scores were significantly lower （P<0.05）. The incidence of complications in the study group was 3.33% （1/30）, which was significantly lower than 20.00% （6/30） in the control group （P<0.05）. Univariate analysis showed that age ≥ 60 years, open surgery, and fracture healing time ≥100 d were potential factors associated with postoperative complications （P<0.05）. Multivariate logistic regression analysis showed that age ≥60 years （OR=5.236）, open surgery （OR=6.814）, and fracture healing time ≥ 100 d （OR=4.937） were independent risk factors for complications （P<0.05）. Conclusion Minimally invasive Kirschner wire tension band internal fixation under arthroscopy has significant advantages in the treatment of patellar fractures, which can effectively shorten fracture healing time, improve knee joint function and motion, enhance patients' daily living ability and quality of life, and its incidence of postoperative complications is significantly lower than that of traditional open surgery. Older age, traditional open surgery, and longer fracture healing time are independent risk factors for postoperative complications, which should be taken seriously in clinical practice.
