Objective To observe the therapeutic effect of arthroscopic synovectomy for tuberculous synovitis of the knee. Methods Ten patients with tuberculous synovitis received arthroscopic biopsy and synovectomy. Postoperatively, isoniazid was injected into the articular cavity, and systemic antituberculosis drugs were administrated. Results These patients received continuous passive motion (CPM) from the second postoperative day. In 9 patients, the flexion ranges of the knee were improved from 90??5? before the surgery to 120??14? after the surgery, and the extension limit of the knee, from 20??3? before the surgery to 5??1? after the surgery, with statistical significant differences ( t =6.9 and 6.3, respectively; P

Objective To describe the depression of premature infants′ mothers and discuss the related influence factors. Methods A total of 86 premature infants′ mothers completed Edinburgh Postnatal Depression Scale at 3-days postpartum in this descriptive study during August 2014 to January 2015 in Obstetrics and Gynecology Hospital of Fudan University. Results The prevalence of postpartum depression in premature infants′ mothers was 25.6% (22/86). Educational levels, family support, character, and number of abortion of mothers, pregnancy complication, gestational age, birth weight, Apgar score, length of hospitalization, and birth with abnormalities of premature infants were found significantly associated with postpartum depression (P<0.05). By Logistic regression, family support (OR=3.253, 95% CI=1.180-8.966) and length of hospitalization (OR=2.905, 95% CI=1.418-5.952) were the risk factors of the postpartum depression at 3-days after delivery. Conclusions Premature infants′mothers at 3-days postpartum presented with obvious postpartum depression. Psychological intervention should be focused on its influence factors.

Objective To investigate the safety and efficacy of stent insertion combined with high-intensity focused ultrasound(HIFU) ablation for malignant obstructive jaundice caused by pancreatic carcinoma.Methods From January 2013 to February 2017,a total of 80 patients with malignant obstructive jaundice caused by pancreatic carcinoma underwent biliary stent insertion in our center,who were divided into combined treatment(stent insertion with HIFU ablation) group(n=38) and solitary stent insertion group(n=42).The stent patency time and survival time were compared between the two groups.Results Relief of jaundice were archived in all patients in both groups.Cholangitis was observed in 7 cases in both two groups.Reobstruction of stent was observed in 15 patients in both two groups.The median stent patency time was 179 days in combined treatment group and 119 days in solitary stent insertion group(P<0.01);the median survival time was 209 days in combined treatment group and 145 days in solitary stent insertion group,the differences were significant(P<0.01).Based on the univariate and multivariate Cox regression analyses,the predictors of prolonging survival included subsequent HIFU ablation after stent insertion and earlier tumor stage(P<0.05).Conclusion Combined biliary stent insertion and HIFU ablation is a safe and effective method for malignant obstructive jaundice caused by pancreatic carcinoma,and seems to extend stent patency time and survival when compared with biliary stent only.

Objective:To evaluate the application value of diffusion tensor imaging (DTI) in guiding the postoperative radiothera-py plan of the gliomas adjacent to the corticospinal tract (CST). Methods:Thirty patients with gliomas adjacent to the CST underwent routine magnetic resonance imaging (MRI) contrast-enhanced scanning and DTI after radiotherapy. Tractography data sets were ac-quired and were fused with the images of corresponding anatomical MRI and computed tomography. The acquired data sets of radio-therapy planning system were imported to assist with the delineation of the target volume, organs at risk, and CST. Two sets of radio-therapy plan, which considered or did not consider the dose protective effect of the CST, were formulated and compared using the treat-ment technique of intensity modulated radiotherapy. Results:The protective radiotherapy and unprotected plans both achieved the thera-peutic dose to the target volume and the protection of the routine organs at risk. In the protective dose (with an optimization program that considered the dose reduction of CST), the maximum and mean radiation doses suffered by the patients' ipsilateral and contra-later-al CSTs were lower compared with the unprotected plan (P<0.05). Conclusion:DTI can identify the location and shape of CSTs, and their relationship with the postoperative radiotherapy target of gliomas. These findings contribute to the formulation of a protective ra-diotherapeutic regimen to keep the CST from the maximum and the mean radiation doses to the largest extent, thereby decreasing the possibility of nerve damage after radiotherapy.

Objective To investigate the short-term efficacy and safety of gefitinib combined with dendritic cells-cytokine induced killer (DC-CIK) cells in the treatment of advanced lung adenocarcinoma.Methods Fifty patients with lung adenocarcinoma who in previous had underwent radiotherapy and first-line chemotherapy failure received DC-CIK in combination with gefitinib treatment,blood count changes,imaging data,carcinoembryonic antigen and changes in the quality of life before and after treatment were compared and evaluated.Results DC-CIK could improve effectively and relieve bone marrow suppression response after chemotherapy and significantly increase the WBC content of blood (P < 0.01).After treatment,the tumor carcinoembryonic antigen (CEA) was significantly lower in patients (P < 0.01).Fifty cases of patients in complete remission (CR) were 0 cases,partial remission (PR) were 24 cases,stable disease (SD) were 17 cases and progression (PD) were 9 cases,and the response rates (RR) were 48%;The quality of life of patients was significantly improved (P < 0.05).Common adverse reactions were rash,diarrhea,chill and fever,but mild symptoms could be relieved after symptomatic treatment.Conclusions Gefitinib with autologous DC-CIK cell infusion second-line treatment of advanced lung cancer have a certain short-term efficacy,without significant adverse reactions.Gefitinib with autologous DC-CIK cell therapy can mitigate the response of bone marrow suppression in patients with advanced lung cancer and improve the quality of life of patients.Long-term effect remains to be investigated.

Objective To study the effect of sodium hyaluronate on the expression of transforming growth factor-β3(TGF-β3) and Smad 6 of the epidural scar tissue. Method Totally 60 male SD rats were randomly divided into two groups:the control group(A, n = 30), sodium hyaluronate group(B, n = 30). 0.25 × 1 cm2 dura mater uncovered area laminectomy was performed at L4 and L5, covered with 0.3 ml sodium hyaluronate in group B, covered with same amount of saline in group A. The animals were sacrificed at 2, 4 and 8 weeks after operation. The specimens were prepared for determination of the expression of TGF-β3 and Smad 6 at scar tissue and the degree of scar adhesion according to Rydell method, and observed the ultrastructure changes of scar tissue with transmission electron microscope. Results At 2 weeks after operation, the expression of TGF-β3 mRNA of two groups were 0.22 and 0.257 ( P = 0.027), respectively. At 4 weeks, group B was was increased significantly, and the mean numbers were 0.362 and 0.411 (P = 0.006). At 8 weeks, the expression of TGF-β3 mRNA of group A was increased significantly, too, but the difference between two groups was significantly, they were 0.427 and 0.470 (P =0.015), respectively. The trend of the expression of TGF-β3 and Smad 6 mRNA was similar. At 2, 4, 8, weeks, the expression was 0.169 and 0.205 (P = 0.089), 0.294 and 0.351 (P = 0.031), and 0.469 and 0.543 (P = 0.021), respectively.In group B the duramater adhesion was decreased (P < 0.05), the proliferation of fibroblasts and fihroblastic function were inhibited (P < 0.05). Conclusions Sodium hyaluronate up-regulated the expression of TGF-β3 and Smad6 and reduced the proliferation and collagen synthesis in fibroblast culture in the scar tissue.
