last follow up, there were 5 cases (9 feet) in TCS group and 2 cases (2 feet) in idiopathic group underwent soft tissue release(χ(2)=6.110, P=0.013). The classification grade of ICFSG score of the two groups without soft tissue release were (2.1±0.6) and (1.8±0.7), the difference was not statistically significant (t=1.765, P=0.082). All the children had no skin ulceration, bedsores, skin allergy and other complications. Conclusion Ponseti method is effective in the treatment of clubfoot secondary to TCS, and the functional recovery is similar to that of children with idiopathic clubfoot.Objective To investigate the early clinical effects of home-based mobile health intervention on knee joint function after anterior cruciate ligament (ACL) reconstruction. Methods This was a prospective randomized controlled trial. Patients undergoing arthroscopic ACL reconstruction alone at the Institute of Sports Medicine, Peking University Third Hospital from April 2019 to December 2019 were elected in the trial.  https://www.selleckchem.com/products/r-hts-3.html  Patients were divided into the intervention group and the control group according to random number method. The control group only received the guidance of the traditional paper rehabilitation schedule, while the intervention group also received personalized guidance of electronic rehabilitation prescription and follow-up notice delivered by a WeChat Mini Program Rehabilitation Cloud Platform in addition to the traditional guidance. Joint range of motion (ROM), visual analogue scale (VAS) and thigh circumference difference were assessed before and after the operation. Independent sample t test or May postoperative rehabilitation effect after ACL construction and the ROM of the knee joint, and reduce the bent-knee pain along with the thigh circumference difference.Objective To examine the clinical treatment methods and short- and mid-term results of traumatic aortic injury (TAI). Methods The clinical data of 30 patients suffering from TAI who were admitted to Department of Cardiothoracic Surgery, General Hospital of Eastern Theater Command from January 2010 to December 2018 were summarized and analyzed retrospectively. All patients were diagnosed as TAI by aortic CT angiography. There were 20 males and 10 females, aging (46.4±15.2) years (range 17 to 76 years). One patient was diagnosed as extensive intramural hematoma (IMH). The other 29 cases had aortic intimal injury, and the primary intimal tear of all these patients was located in the isthmus of descending aorta. There were 2 cases of ulcer-like changes combined with IMH, and 27 cases of traumatic aortic dissection (TAD) including 23 cases of localized TAD and 4 cases of extensive TAD. Endovascular repair, artificial vascular replacement or conservative treatment were performed according to the patient's specific and survived healthily without new aortic events. Conclusions Most of TAD cases are ascribed to Stanford type B aortic dissection, and a satisfactory short-term and mid-term result can be achieved by emergency TEVAR in most patients. Some patients can achieve good long-term results by open surgery with artificial vascular replacement.Objective To examine the blood protective effect of autologous platelet-rich plasma separation for cardiac valve replacement under cardiopulmonary bypass. Methods Sixty patients who underwent cardiac valve replacement under cardiopulmonary bypass from August 2018 to May 2019 in Shanghai Chest Hospital, Shanghai Jiao Tong University were randomly divided into control and treatment groups(each 30 cases). There were 33 males and 27 females, aged (52.0±8.4) years (range 35 to 65 years). Autologous platelet separation was performed in the treatment group after anaesthesia administration and was completed before systemic heparinisation. Platelet separation was not performed in the control group. The thromboelastogram, blood routine, blood coagulation, perioperative fluid infusion, allogeneic blood transfusion, postoperative pleural fluid volume and postoperative fibrinogen were recorded before the operation, and 1 hour and 24 hours post operation. The two groups' data was compared by t test, Kruskal-Wallis test, Mann-Whitney U test or χ(2) test. Repeated measurement analysis of variance was used to compare platelet and coagulation indexes at different times. Results The perioperative red blood cell transfusion of 0, 1~2, 3~4,>4 units with 6, 11, 1, 12 cases in treatment group and 14, 8, 6, 2 cases in control group (Z=-2.516, P=0.012). The postoperative fibrinogen of 0, 1, 2 units with 19, 2, 9 cases in treat group and 26, 2, 2 cases in control group (Z=-2.190, P=0.029). There was no significant difference in the cost of blood transfusion between the two groups during admission ((1 732±1 275) yuan vs. (1 176±941) yuan; t=-1.570, P=0.125). Conclusion The use of autologous platelet-rich plasma separation can reduce the amount of allogeneic blood transfusion during valvular surgery under cardiopulmonary bypass.Objective To compare the short-term results of laparoscopic pancreaticoduodenectomy and open pancreaticoduodenectomy in periampullary carcinoma patients. Methods The clinical data of patients with periampullary carcinoma who underwent laparoscopic pancreaticoduodenectomy or open pancreaticoduodenectomy at Department of Hepatopancreatobiliary Surgery, Jinhua Hospital, Affiliated to Zhejiang University School of Medicine from January 2013 to February 2018 were collected. Totally 127 patients were included in the study. There were 73 males and 54 females, aged (61.2±9.4) years (range 37-80 years). Propensity score matching method was used to perform 1∶1 matching between laparoscopic pancreaticoduodenectomy and open pancreaticoduodenectomy. Perioperative outcomes and overall survival were compared between the two groups using t test, χ(2) test, Fisher exact probability, Kaplan-Meier curve and Log-rank test, respectively. Results A total of 32 pairs of patients were successfully matched by propensity score matchin and feasible for the treatment of periampullary carcinoma. It not only has advantages of less trauma and faster recovery, but also achieves similar of lymph node dissection and equivalent short-term prognosis when compared with open approach.
