Methods A total of 86 CSR patients treated from February 2017 to February 2020 in our hospital were randomly assigned to two groups, with 43 cases in each group. The conventional group took conventional rehabilitation; the combined group took Mulligan mobilisations with movement and muscle energy techniques. Clinical assessment scale for cervical spondylosis (CASCS) scores, neck disability index (NDI) scores, active range of motion (AROM), Short-form 36 Health Survey Questionnaire (SF-36) scores, Visual Analogue Scale (VAS) scores, and muscle pressure pain threshold were compared before and after the treatment. Results The CASCS score, AROM, and SF-36 score were significantly higher and the NDI score and VAS score were significantly lower in the combined group than those in the conventional group (P<0.05). The pressure pain thresholds of trapezius, levator scapulae, and suboital muscles in the combined group were significantly lower than those in the conventional group (P<0.05). Conclusion Mulligan mobilisations with movement plus muscle energy techniques can relieve the clinical symptoms of cervical spondylosis, such as reducing neck disability, increasing the active range of motion, and reducing pain, and thereby improve the quality of life of patients.

Research progress on graft selection in anterior cruciate ligament reconstruction FENG Jianhao, WANG Jiaqi Surgical Research and New Technique    2023, 12 (2): 125-130.   DOI: 10.3969/j.issn.2095-378X.2023.02.013 Abstract （407）      PDF（pc） （636KB）（652）       Knowledge map    Anterior cruciate ligament （ACL） is one of the most vulnerable structures during sports and an essential anterior stabilizing structure in the knee joint. ACL injury can impair a patient’s ability to move, and if not properly treated in time, it often results in serious adverse complications like meniscal and articular cartilage damage, and even traumatic osteoarthritis. Currently, ACL reconstruction is the standard treatment for ACL injury, and the choice of grafts has a significant impact on patients’ postoperative functional recovery and surgical success. Autografts are the most commonly used grafts and have the most stable efficacy, but they have drawbacks like limited sources and donor-site morbidity. Although having greater adaptability, allografts carry a risk of immune rejection and the spread of diseases. Artificial ligaments are appropriate for those who must quickly resume their athletic activities, but they are technically challenging and have not been shown to be long-term effective. Due to the numerous issues with traditional grafts, recent rapid advancements in tissue engineering techniques are generating novel ideas for ACL reconstruction. In order to aid in the treatment of ACL injury, this article discussed the benefits, drawbacks, and clinical effectiveness of different grafts used in ACL reconstruction.

Nowadays, the diagnosis and treatment of breast cancer has gradually changed from traditional treatment methods to individualized and precise treatment methods. Interferon-stimulated gene 15 （ISG15） is related to the occurrence and development of many malignant tumors, and participates in tumor-related immune responses and the resistance of many chemotherapeutics. ISG15 can promote breast cancer cell movement, and participate in breast cancer-related tumor immunotherapy and various signaling pathways. These research findings provide new insights for breast cancer treatment. In this paper, the structure and function of ISG15, and its correlation with tumors, especially with breast cancer, were reviewed. Reference | Related Articles | Metrics

Methods Clinical data of 24 cases （48 eyes） from January 2016 to January 2017 were retrieved. All patients received ICL V4C implantation by the same operator. The patients were aged 21 to 45 years, average （32.8±6.5） years. The equivalent ball mirror was -4D~-18D, average （8.25±4.5） D. The astigmatism was between -0.5 D and -4 D, average （1.25±0.75） D. The intraocular pressure ranged between 10-21 mmHg with an average of （15.9±2.82） mmHg. The postoperative arch height was 150-750 μm. The patients were followed up for three years to observe the effect of ICL V4C implantation on intraocular pressure. Results The intraocular pressure values of patients at 1 week, 1 month, 3 months, 6 months, 1 year, 2 years, and 3 years after the operation were all within the range of 10-21 mmHg, which did not exceed threshold. The difference between the two eyes were all less than 5 mmHg and significantly lower than that of the control group （P<0.05）. Conclusion The intraocular pressures of myopic patients are all within a normal and safe range after ICL V4C implementation, and are not obviously changed three years after the surgery compared with before.

Progress in the treatment of lunate fracture ABUDUREYIMU Abudukeremu, JI Jiaqing, YIN Ziyue, QIAN Jikui, FAN Jian Surgical Research and New Technique    2024, 13 (1): 67-71.   DOI: 10.3969/j.issn.2095-378X.2024.01.017 Abstract （374）      PDF（pc） （1195KB）（301）       Knowledge map    Fractures of lunate bone are rare injuries of the wrist that are usually resulted from high-energy trauma and are typically accompanied by other carpal injuries, such as scaphoid bone, capitate bone, radial styloid, and distal radius fracture. Misdiagnosis,missed diagnosis or inappropriate treatment in clinical practice lead to a high nonunion rate of lunate fractures, which often affects the movement of the wrist and even leads to complications such as osteonecrosis or loss of wrist function. The potential pathogenesis, therapeutic method,and prognosis of lunate fractures are still controversial. This article reviewed domestic and foreign literature on the classification, imaging characteristics and treatment methods from the perspectives of anatomical characteristics and injury mechanism of the lunate, so as to provide guidance for improving the prognosis of lunate fractures.

Application of controlled low central vein pressure in complex laparoscopic hepatectomy HE Longguang, CHEN Qinshou, LI Dasheng, LI Fuliang, HUANG Junwei Surgical Research and New Technique    2021, 10 (1): 14-16.   DOI: 10.3969/j.issn.2095-378X.2021.01.004 Abstract （355）      PDF（pc） （1266KB）（708）       Knowledge map    Objective To investigate the effect of controlled low central vein pressure on complex laparoscopic hepatectomy. Methods From January 2018 to May 2020, 60 patients with complex laparoscopic hepatectomy were randomly divided into an observation group （n=30） and a control group （n=30）. The observation group was treated by controlled low central venous pressure technique to maintain central venous pressure （CVP） at 1-3 cmH2O and SAP ≥ 90; while the control group was given conventional operation to keep CVP at 6-12 cmH2O. The intraoperative blood loss, operation time, blood gas indicators, liver and kidney functions, and bile leakage complications were compared between the two groups. Results The operation indexes in the observation group were better than those in the control group （P<0.05）. On postoperative day 1, the blood urea nitrogen, serum creatinine, alanine aminotransferase, and total bilirubin in both groups were increased, while the indexes in the observation group were slightly elevated （P<0.05）; there was no difference in pH and SpO2 between the two groups （P>0.05）, while the PaO2 and BE in the observation group were lower, and the HCO-3 was higher than those in the control group （P<0.05）. The incidence of bile leakage was lower in the observation group （P<0.05）. Conclusion In patients undergoing complex laparoscopic hepatectomy, the use of controlled low central venous pressure technique can reduce the amount of bleeding and blood transfusion and reduce the incidence of complications, thereby optimize operation effect, greatly improve the safety of liver surgery, and shorten the length of hospital stay, while not produce significant adverse effects on liver and kidney functions.
