Objective To explore serratus anterior muscle transplantation for the repair of soft tissue defects in foot and ankle. Methods Seventeen patients consisted of 11 males and 6 females aging from 13 to 58 years with the mean age of 35.2 years. The anatomical parameters of serratus anterior of 17 cases were measured, the thickness of the muscle was (1.24?0.65) cm, and the diameter of origin point of the nutrient artery to the muscle was (1.4?0.6) mm. There were two veins arising from the muscle, the diameter of larger one was (2.5?0.8) mm. The length of vascular pedicle was (8.31?1.48) cm. 17 patients with soft tissue defect of foot and ankle were treated with free serratus anterior muscle transfer and split skin graft overlying the muscle. The primary lesions were soft tissue defect around the ankle and Pilon fracture in 5 cases, non-union of distal tibial fracture in 3, Achilles tendon and soft tissue defect in 3, metatarsal fracture and soft tissue defect in 4, and calcaneal fracture with soft tissue defect in 2. All of the patients suffered from infection or exposure of bone or applied plate, the area of soft tissue defect ranged from 4.5 cm?6 cm to 11 cm?13 cm. Results The average operative time was (6.5?1.2) hours. The complications included local hematoma in 2 cases, superficial infection in 2, winged scapula without function loss in 1,scar pain in 2, and numbness of lateral thoracic wall in 1. Furthermore, weakness and decreased shoulder mobility were noted in 3 patients comparing with the contralateral side, but the condition improved half year following the operation. The transferred muscle flap appeared thinner and less bulky , and healed intimately with the adjacent foot tissue, the patients resumed good function in walking. Conclusion The serratus anterior muscle flap is a good choice for treatment of soft tissue defects in foot and ankle.

Abstract: Objective To investigate the prevalence and influencing factors of depressive symptoms among primary and middle school students in Xihu District, Hangzhou City, so as to provide insights into depression control among primary and middle school students. Methods: Students were sampled from two primary schools, two junior high schools, two ordinary high schools and one vocational high school in Xihu District using a stratified cluster random sampling method from September to November, 2021. Participants' demographics, diet, exercise, sleep and campus bullying were collected using questionnaire surveys. The depressive symptoms were evaluated using the Chinese version of the Center for Epidemiologic Studies-Depression Scale (CES-D), and factors affecting the depressive symptoms were identified among primary and middle school students using a multivariable logistic regression model. Results: A total of 1 518 students were investigated, including 518 primary school students (34.12%), 363 junior high school students (23.91%), 463 ordinary high school students (30.50%) and 174 vocational high school students (11.46%). Of all participants, there were 805 males (53.03%). The prevalence of depressive symptoms was 38.87% among the participants, and was 36.10%, 42.42%, 42.33% and 30.46% among primary school, junior high school, ordinary high school and vocational high school students, respectively. The multivariable logistic regression analysis showed that gender (OR=1.601, 95%CI: 1.289-1.989), type of school (junior high school, OR=1.299, 95%CI: 0.974-1.734; ordinary high school, OR=1.351, 95%CI: 1.025-1.780; vocational high school, OR=0.862, 95%CI: 0.585-1.272), frequency of fresh vegetable intake (less than once daily, OR=0.454, 95%CI: 0.304-0.679; once and more daily, OR=0.359, 95%CI: 0.235-0.548), duration spent on the internet (0.5 to 1 h daily, OR=1.447, 95%CI: 1.044-2.006; 1 h and longer daily, OR=1.456, 95%CI: 1.072-1.978), sufficient sleep (OR=0.525, 95%CI: 0.371-0.744), suffering from campus bullying (OR=1.992, 95%CI: 1.491-2.661) were associated with the development of depressive symptoms. Conclusions The prevalence of depressive symptoms is high among primary and middle school students in Xihu District. Gender, type of school, dietary behaviors, sleep duration and campus bullying are factors affecting the development of depressive symptoms.

Objective:To investigate the clinical effect of esophagofundostomy combined with pericardial devascularization in the treatment of upper gastrointestinal hemorrhage caused by portal hypertension.Methods:The clinical data of 108 patients with portal hypertension admitted to the Affiliated Hospital of Inner Mongolia Medical University from Feb 2009 to Feb 2015 were analyzed. Among them 42 patients underwent esophagofundostomy combined with pericardial devascularization as the study group, and 66 patients underwent pericardial devascularization only as the control group. All patients presented with splenomegaly or hypersplenism; the spleen was routinely removed during the operation.Results:The difference of operation time between the study group and the control group was statistically significant [(157±41) min vs. (143±27) min, t=2.81, P<0.05]. The improvement in the esophagogastric varices in the study group within 6 months was significantly better than that in the control group( Z=2.47, P<0.05). In addition, the rebleeding rates of varicose veins within 1, 3 and 5 years in the study group was 2%, 5% and 10%, while that in the control group was 15%, 21% and 26% (χ 2=5.49, 4.27, 4.31, all P<0.05). Conclusions:Esophagofundostomy combined with pericardia devascularization achieves complete devascularization and low rebleeding rate.

Distal pancreatectomy is the first choice for the treatment of benign, malignant, inflammatory and traumatic lesions in the body and tail of pancreas. In recent decades, abdominal drainage has been a common therapeutic option to reduce postoperative complications in abdominal surgery. However, with the rise of the theory of accelerated rehabilitation surgery, the safety and effectiveness of postoperative abdominal drainage have been controversial, and the placement and management of intraoperative drainage have been questioned. This article reviewed the related literatures at home and abroad, and summarized the controversial issues such as whether to place abdominal drainage tube after distal pancreatectomy, the choice of postoperative drainage mode, and the timing and indication of abdominal drainage tube removal.

Onodera prognostic nutrition index (OPNI) is a simple and effective parameter. It is calculated by serum albumin level and peripheral blood lymphocyte count. Initially, OPNI is used to assess preoperative nutritional status and surgical risk. In recent years, researchers have found that OPNI is related to the prognosis of many tumors. Simple and accurate prognosis evaluation can help to select treatment methods for digestive system malignant tumors, determine the best pre-operative treatment time and operation time, and improve the survival rate of patients with diges-tive system malignant tumors. The authors review the related literatures at home and abroad, and summarize the research advances in the prognostic value of OPNI for malignant tumors of digestive systems.

Objective To evaluate the differences in efficacy,safety and economics of vancomycin hydrochloride for injection between two manufacturers based on real-world data.Methods A total of 6 757 cases of intravenous use of vancomycin hydrochloride for injection from different manufacturers between January 1,2013 and December 31,2019 in the Affiliated Drum Tower Hospital of Nanjing University Medical School were retrospectively analyzed,and 5308 cases were matched by 1∶1 propensity score method,including 2 654 cases in the group A(domestic drug group)and 2 654 cases in group B(the innovator drug group).The differences in efficacy and safety between the two groups were compared.Cost-effectiveness analysis was used to compare the drug economics of the two groups.Results There were no significant differences in clinical cure rate,bacterial clearance rate,and incidence of adverse events between the two groups(P>0.05).In terms of economics,the average cost of vancomycin per capita,average daily cost of vancomycin and average cost of antibiotics per capita were significantly different between the two groups(P<0.05),and the cost of group B was higher than that of group A.Conclusion The efficacy and safety of vancomycin hydrochloride for injection were consistent between the two manufacturers.

BACKGROUNDThe purpose of this retrospective study was to compare the surgical outcomes of simple discectomy and instrumented posterior lumbar interbody fusion (iPLIF) in patients with lumbar disc herniation and Modic endplate changes. Our hypothesis was that iPLIF could provide better outcome for patients with refractory lumbar disc herniation and Modic changes (LDH-MC).

METHODSNinety-one patients with single-segment LDH-MC were recruited. All patients experienced low back pain as well as radicular leg pain, and low back pain was more severe than leg pain. Forty-seven patients were treated with discectomy and 44 were treated with iPLIF. The outcomes of both low back pain and radicular leg pain using visual analogue scale (VAS) as well as the clinical outcome related to low back pain using Japanese Orthopaedic Association (JOA) score were assessed before and 18 months after surgery, respectively.

RESULTSBoth low back and leg pain were significantly improved 18 months after simple discectomy and iPLIF. Compared to patients undergoing simple discectomy, low back pain was significantly reduced in patients undergoing iPLIF, but there was no significant difference in leg pain between two groups. Solid fusion was achieved in all patients who underwent iPLIF.

CONCLUSIONSIn patients with LDH-MC, iPLIF can yield significantly superior outcome on the relief of low back pain compared to simple discectomy. Simple discectomy can relieve radicular leg pain as efficient as iPLIF. Accordingly, iPLIF seems to be a reliable treatment for patients with LDH-MC and predominant low back pain.
