In order to correct the dysfunction of head and neck with scar contracture, since 1980, sixty-two cases were undertaken the operation by using local skin flap to repair the soft tissue defect after scar resection. The skin flaps included pedicled delto-thoracic skin flap in 26 cases, cervico-thoracic skin flaps in 25 cases, cervico-shoulder flaps in 6 cases, pedicled vascularized extralong delto-thoracic skin flap in 4 cases and free parascapular flap in 1 case. Sixty cases had total survival of the flaps and 2 flaps had partial necrosis. After 1 to 10 years follow-up, the appearance and function of neck were excellent. It was suggested that grafting local skin flap was a good method to treat cicatricial deformity of neck especially using the skin flap with pedicle and vascular bundle.

ObjectiveTo evaluate the effect on complication after esophagectomy by comparing the different methods of anastomosis (cervical versus thoracic anastomosis). MethodsWe searched the following databases including PubMed, EMbase, The Cochrane Library, Web of Science, CBM, CNKI, VIP and Wanfang database to identify randomized controlled trials (RCTs) of cervical versus thoracic anastomosis for esophagectomy patients from establishment of each database to October 30, 2014. Quality of the included RCT was evaluated. Meta-analysis was conducted by using RevMan 5.2 software. ResultsWe finally identified 4 RCTs involving 267 patients. In terms of the postoperative complication, the incidence of anastomotic leakage (RR=3.83, 95%CI 1.70 to 8.63, P=0.001) with cervical anastomosis was significantly higher than that of the patients with thoracic anastomosis. However, there was no statistical difference in incidence of anastomotic stricture (RR=1.04, 95%CI 0.62 to 1.76, P=0.87), pulmonary complication (RR=0.73, 95%CI 0.27 to 1.91, P=0.52), and mortality (RR=0.89, 95%CI 0.40 to 1.97, P=0.77) between cervical and thoracic anastomosis. ConclusionCompared with thoracic anastomosis, the method of cervical anastomosis is associated with a higher incidence of anastomotic leakage. But there are many unclear factors about anastomotic stricture, pulmonary complication and mortality, further measurement should be taken.
ObjectiveTo systematically review the correlation between mTOR protein expression and different clinical pathological features as well as the response to radiotherapy and chemotherapy of cervical cancer. MethodsWe electronically searched databases including The Cochrane Library (Issue 1, 2015), PubMed, EMbase, CNKI, CBM, VIP and WanFang Data from inception to April 2015 to collect case-control studies investigating the correlation between mTOR protein expression and different clinical pathological features as well as the response to radiotherapy and chemotherapy of cervical cancer. Two reviewers independently screened literature, extracted data and assessed the risk bias of the included studies. Then meta-analysis was performed using RevMan 5.2 software. ResultsA total of 8 case-control studies involving 591 patients were included. Among these cases, 365 cases were in the cervical cancer group, 135 cases were in the cervical intraepithelial neoplasia (CIN) group, and 91 cases were in the normal cervix tissue group. The results of meta-analysis showed that:(1) Compared with the normal cervix tissue group, mTOR protein was overexpressed in the cervical cancer group (OR=24.14, 95%CI 4.47 to 130.35, P=0.000 2) and the CIN group (OR=4.71, 95%CI 2.15 to 10.33, P=0.000 1); Compared with the CIN group, mTOR protein was overexpressed in the cervical cancer group (OR=5.12, 95%CI 2.96 to 8.86, P<0.000 01). (2) Compared with the non-lymphnode-metastasis group, mTOR protein was overexpressed in the lymph node metastasis group (OR=3.29, 95%CI 1.61 to 6.69, P=0.001); Compared with the FIGO I group, mTOR protein was overexpressed in the FIGO Ⅱ group (OR=3.00, 95%CI 1.49 to 6.04, P=0.002); Compared with the radiotherapy and chemotherapy responsive group, mTOR protein was overexpressed in the non-response group (OR=15.64, 95%CI 3.17 to 77.15, P=0.000 7). In addition, there was no significant difference between the medium/high differentiation group and low differentiation group (OR=1.70, 95%CI 0.75 to 3.81, P=0.20). ConclusionmTOR protein expression is associated with cervical cancer, and mTOR protein overexpression was associated with lymph node metastasis, higher FIGO and non-response to radiotherapy and chemotherapy. Due to the limited quantity and quality of the included studies, the above conclusion needs to be further verified by more high quality studies.
Objective To explore the related factors of femoral stem anteversion (FSA) after total hip arthroplasty (THA), so as to provide reference for clinical design of FSA before operation and reduce the risk of hip dislocation after arthroplasty. Methods Ninty-three patients (103 hips) who underwent THA between October 2021 and September 2022 and met the selection criteria were selected as the study subjects. Among them, there were 48 males and 45 females with an average age of 58.5 years (range, 25-88 years). Body mass index was 18.00-37.84 kg/m2, with an average of 24.92 kg/m2. There were 51 cases (57 hips) of osteonecrosis of femoral head, 35 cases (39 hips) of hip osteoarthritis, and 7 cases (7 hips) of congenital hip dysplasia. Based on CT images, the following indicators were measured: preoperative femoral neck anteversion (FNA), preoperative femoral rotation angle (FRA), preoperative acetabular anteversion (AA), and preoperative combined anteversion (CA; the sum of preoperative FNA and AA); postoperative FSA and the change in femoral anteversion angle (the difference between postoperative FSA and preoperative FNA). Based on preoperative X-ray films, the following indicators were measured: femoral cortical thickness index (CTI) and canal flare index (CFI), the proximal femoral medullary cavity was classified according to Noble classification (champagne cup type, normal type, chimney type), neck-shaft angle (NSA), and femoral offset (FO). Pearson correlation analysis, one-way ANOVA, and Point-biserial correlation analysis were used to investigate the correlation between postoperative FSA, postoperative change in femoral anteversion angle, and patient diagnosis, proximal femoral medullary cavity anatomy type, gender, age, as well as preoperative FNA, FRA, AA, CA, NSA, FO, CTI, and CFI. FSA was used as the dependent variable and the independent variables that may be related to it were included for multiple linear regression analysis. Results Based on CT image measurement, preoperative FNA was (15.96±10.01)°, FRA (3.36±10.87)°, AA (12.94±8.83)°, CA (28.9±12.6)°, postoperative FSA (16.18±11.01)°, and postoperative change in femoral anteversion angle was (0.22±9.98)°. Based on preoperative X-ray films measurements, the CTI was 0.586±0.081; the CFI was 4.135±1.125, with 23 hips classified as champagne cup type, 68 hips as normal type, and 12 hips as chimney type in the proximal femoral medullary cavity anatomy; NSA was (132.87±7.83)°; FO was (40.53±10.11) mm. There was no significant difference between preoperative FNA and postoperative FSA (t=−0.227, P=0.821). Pearson correlation analysis showed that postoperative FSA was positively correlated with preoperative FNA, preoperative CA, postoperative change in femoral anteversion angle, and age (P<0.05), while negatively correlated with preoperative FRA (P<0.05). The postoperative change in femoral anteversion angle were positively correlated with preoperative FRA and postoperative FSA (P<0.05), and negatively correlated with preoperative CA and FNA (P<0.05). One-way ANOVA analysis showed that the above two indicators were not correlated with diagnosis and the proximal femoral medullary cavity anatomy type (P>0.05). Multiple linear regression analysis showed a linear correlation between FSA and FNA, CA, age, and FRA (F=10.998, P<0.001), and the best fit model was FSA=0.48×FNA–2.551. Conclusion The factors related to FSA after THA include patient’s age, preoperative FNA, CA, FRA and postoperative femoral anteversion, of which preoperative FNA is the most closely related. When designing a surgical plan before surgery, attention should be paid to the patient’s preoperative FNA, and if necessary, CT around the hip joint should be scanned to gain a detailed understanding of the proximal femoral anatomical structure.
