A novel nerve repairing material poly [LA-co.（GIc-alt-Lys）] （PLGL） was synthesized. The viability and growth of Schwann cells （SCs） co-cultured With poly （D, L- lactic acid）（PDLLA） films （control group） and PLGL films were evaluated by MTT assay and SEM observation. Then, contact angle measurement, histological assessment and enzyme-linked immunosorbent assay （EliSA） testing on inflammatory-related cyto- kines such as IL-10 and TGF-β1 were performed. The results showed that, compared with PDLLA, PLGL films possesses better hydrophilicity, biocompatibility, degradation property and less inflammatory reaction. The present study indicated that PLGL scaffolds would meet the requirements of artificial nerve scaffold and have a potential application in the fields of nerve regeneration.

BACKGROUND: Laparoscopic cholecystectomy (LC) has become the 'gold standard' in treating benign gallbladder diseases. Increasing laparoscopic experience and techniques have made laparoscopic subtotal cholecystectomy (LSC) a feasible option in more complex procedures. In recent years, few studies with a few cases of LSC have reported good results in patients with various types of cholecystitis. This study was designed to evaluate the feasibility, indications, characteristics and benefits of LSC in patients with complicated cholecystitis. METHODS: Altogether, 3485 patients were scheduled to receive LC during the past 4 years at our institute. Among them, 168 patients with various complicated forms of cholecystitis were treated by LSC. Meanwhile, the other 3317 patients who received standard LC were enrolled as the control group. Perioperative data from the two groups were collected and retrospectively analyzed. RESULTS: In the LSC group, 135 patients suffered from acute calculic cholecystitis, 18 from chronic calculic cholecystitis with cirrhotic portal hypertention, and 15 from chronic calculic atrophy cholecystitis with severe fibrosis. These patients constituted 4.8% of the total patients who underwent LC (168/3485) in the same period at our institute. In 122 patients, the cystic duct and artery were clipped before division. In another 46 patients, the gallbladder was initially incised at Hartmann's pouch. Five patients (3.0%) were converted to open subtotal cholecystectomy. The median operation time for LSC was 65.5±15.2 minutes, estimated operative blood loss was 71.5±15.5 ml, and the time to resume diet was 20.4±6.3 hours. Thirteen patients (7.7%) had local complications. The mean postoperative hospital stay was 4.2±2.6 days. In the LC group, 2887 had chronic calculic cholecystitis, 312had acute calculic cholecystitis, 47 had chronic calculic atrophy cholecystitis, and 71 had polypus. Seventeen patients (0.5%) were converted to open cholecystectomy. The median o

采用溶胶-凝胶（Sol-Gel）过程和旋涂法制备了Zn-Sn-O系统薄膜。通过对干凝胶的热重-差示扫描同步热分析（TG-DSC）,研究了干凝胶在烧结过程中的反应历程。采用X射线衍射（XRD）、X射线光电子能谱（XPS）、场发射扫描电镜（FE-SEM）以及紫外-可见透过率（UV-Vis）等表征了烧结后薄膜的晶相、晶格缺陷、微观形貌以及紫外-可见光透过率。本文还研究了烧结温度、N2气氛热处理以及组成变化对薄膜电阻率的影响,结果表明：偏锡酸锌ZnSnO3晶体薄膜具有较低的电阻率;当nZn/（nZn＋nSn）=50.3at%时,薄膜的电阻率达极小值,约为8.0×102Ω.cm。偏锡酸锌ZnSnO3晶体的导电机理研究表明：晶格中间隙阳离子含量的增加有利于薄膜电阻率的降低,而氧空位的形成则使其电阻率升高。薄膜的紫外-可见光透过率（UV-Vis）表明：偏锡酸锌ZnSnO3晶体薄膜在400~900 nm的可见光波段透过率可达80%以上。

BACKGROUND: Laparoscopic cholecystectomy (LC) has been widely adopted in treating benign gallbladder disea- ses. Cirrhosis and cirrhotic portal hypertension (CPH) are contraindicated for LC in its early period. In recent years, several studies have reported liberal use of LC in patients with cirrhosis. But its benefits and successful use in patients with CPH are less documented. This study was designed to evaluate the feasibility, safety and technical characteristics of LC in CPH patients. METHODS: In 38 patients with symptomatic gallbladder disease and CPH, 19 belonged to Child A class, 15 Child B class and 4 Child C class. Perioperative data of these pa- tients were collected and analyzed. RESULTS: LC was successfully performed in 36 patients, and 2 patients (5.3%) were converted to open cholecystec- tomy (OC) for difficulty in management of bleeding under laparoscopy and dense adhesion of Calot' s triangle. The sur- gical time was 62.6±15.2 minutes. The estimated amount of intraoperative hemorrhage was 75.5±15.5 ml. No blood transfusion was necessary. The time to resume diet was 18.3 ±6.5 hours. Seven postoperative complications in 5 patients (13.2%) included port-site infection (1 patient), respiratory infection (2), upper digestive tract bleeding (1), slight hepatic encephalopathy (1) and increased ascites (2). All patients were cured and discharged from the hospital within 5.6±2.4 days after LC. CONCLUSIONS: Despite LC is difficult for CPH patients, it is feasible and relatively safe. To make LC successful in patients with CPH, it is necessary for surgeons to acquaint with the technical characteristics of LC and emphasize me- ticulous perioperative management.

Poly(3,4-ethylenedioxythiophene) (PEDOT), heralded as the “king” of conducting polymers, is esteemed in bioelectronics for its mixed electronic and ionic conductivity, mechanical properties compatible with biological tissues, tunable healing ability and stability in diverse environments [1]. Based on additive manufacturing of three-dimensional structures,PEDOT realizes the implementation in the efficient production of flexible bioelectronics, the construction of intricate electrode-neural implantations, and the development of smart brain-computer-interfaces [2].

以Na2WO4.2H2O为主要原料,采用液相法(80℃)和离子交换-水热法(150℃)分别制备了六方WO3.0.33H2O和以正交相为主的混合晶型WO3.0.33H2O。通过对2种晶型WO3.0.33H2O材料进行X射线衍射(XRD)、场发射电子扫描显微镜(FE-SEM)、红外光谱(FTIR)、X射线光电子能谱(XPS)和循环伏安测试,表征了产物的晶相和结构等。正交WO.30.33H2O结构中由于相邻钨氧八面体层的相互位移而形成空隙,六方WO3.0.33H2O结构中没有位移则形成孔道;正交WO3.0.33H2O具有比六方WO3.0.33H2O更短键长的W=O和更负的导带位置。紫外-可见透射光谱研究表明,六方WO.30.33H2O具有更明显的电致变色效应,可能是因为结构中的孔道使H+易扩散使六方WO.30.33H2O更易发生氧化还原反应。光催化性能研究表明,正交WO3.0.33H2O具有更负的导带位置,价带电子跃迁后易于向电子受体转移,抑制了电子和空穴的复合,使得混合晶型WO3.0.33H2O的紫外光光催化能力相对六方WO.30.33H2O更强。
