Objective To analyze the current situation of institutional care for people with disabilities in Shanghai, China. Methods Sec-ondary data were collected from the synthetical information platform of Shanghai Disabled Persons' Federation, including data about the res-idential institutions and people with disabilities living in the institutions from 2004 to 2015. Results The number of residential institutions and people with disabilities showed an increasing tendency from 2004 to 2015. At the end of 2015, there was 368 residential institutions in Shanghai, providing institutional care for 5821 people with disabilities. People in the institutions were mainly with intelligence disability and mental disability, and mainly in 35 to 59 years old. Conclusion The institutional care for people with disabilities was generally in a good condition in Shanghai and met people's needs.

Objective To construct pseudotyped retroviral vector MuLV/VSV-G and transfer it into rabbit smooth muscle cells (SMC) in order to provide a high-efficiency vector for SMC gene transfer. Methods We constructed pseudotyped retroviral vector MuLV/VSV-G containing the previously reported gene lacZ, determined the titer, and determined the efficiency of gene transfer into SMC mediated by pseudotyped retroviral vector MuLV/VSV-G. Finally the transfer efficiency was compared with that by MuLV. Results MuLV/VSV-G vector was constructed. The titer of the vector was 6-7.8×10~6CFU, the transfer efficiency was (92±12)% by using MuLV/VSV-G vector and (24±5)% by MuLV vector. Conclusion Pseudotyped retroviral vector MuLV/VSV-G which was constructed successfully is a kind of high-efficiency gene transfer vector in smooth muscle cells.

AIM:To observe the effect of Tianbing Tiaodu Capsule on learning and memory,and expression of BDNF in brains of picrotoxin-kindled epilepsy rats. METHODS: The epilepsy rat model was established by picrotoxin in jection.The effects of Tianbing Tiaodu Capsule were observed on the model groups and compared with sodium valproate group and piracetam group.The behavior and emotion of epilepsy rats were observed by Action Observing Box.Its reactions were assessed by snatching rats with the gloves.The learning and memory abilities were tested after Morris water maze training.The brains were made into paraffin sections,processed for HE staining and Nissl staining.The expression levels of BDNF were measured by immunohistochemical S-P techniques. RESULTS: Taking Tianbing Tiaodu Capsule,the behavior and emotion of epilepsy rats were markedly improved.The escape latency of searching the platform were shortened and times of rats acrossing the original platform were increased.Tianbing Tiaodu Capsule could reduce neuron impairment and necrosis on the cordex and Hippocampus of epilepsy rats,improve the loss of Nissl bodies,increase BDNF positive remarks. CONCLUSION: Tianbing Tiaodu Capsule can markedly improve impairment of learning and memory in picrotoxin-kindle epilepsy rats,which might be the result of increaseing BDNF expression,the protection of Nissl bodies,making protein synthesize,improving neuron function.

BACKGROUND:Comparative study results between the efficacies of traditional Chinese medicine (TCM) therapy with Western medicine therapy in the treatment of knee osteoarthritis remain controversial. Currently, meta-analysis studies mainly focuson comparison of the efficacy between TCM and Western medicine,butlack investigations among TCM therapies. Itmakes usdifficult tofulyunderstand the efficacy of TCM therapy for knee osteoarthritis.
OBJECTIVE:To compare the efficacies of TCM therapy with intra-articular injection of hyaluronic acid for knee osteoarthritis using a networkMeta-analysis method.
METHODS:PubMed, The Cochrane Library (tissue 10, 2015), EMbase, CNKI, CBM, VIP, Wangfang databaseswere searchedup to October 20, 2015forrelevantrandomized controled trialsaddressingthe efficacies of TCM therapyversusintra-articular injection of hyaluronic acid for knee osteoarthritis. Two reviewers independently selected the studies, extracted information, and assessed the quality of included trials. Data extraction from eligible studies was pooled and meta-analyzed using Stata12.0 and WinBUGS1.4.3softwares. Odd ratios with their 95% confidence interval were estimated as effect size between treatments.
RESULTS AND CONCLUSION:A total of 59 randomized controled trials involving 6 155 patients with knee osteoarthritis and 12 treatment strategies were included. The results of network meta-analysis showed that TCM comprehensive therapy wassuperior to the TCM monotherapy and intra-articular injection of hyaluronic acid. Among thesetherapies, the efficacy of needle scalpel combined with acupuncture is optimal. TCM comprehensive therapies may be the best choice to treat patients with knee osteoarthritisofKelgren-LawrenceII-III. Morelarge-scaleand wel-designedrandomized controled trials are stil warranted due to the limitation of the present study.

Objective To explore the imaging features and clinical significance of solitary costal hot spots on bone scintigraphy (BS). Methods Eighty-four patients with single costal hot spots were enrolled in the study. The sites of lesions were classified into four types: junction betweenaor rib. The shapes of hot spots were classified into three forms: Punctiform, clumping and strip. The above data were respectively analyzed. Results Single hot spots were mainly showed in the punctiform and strip shapes, and the distribution of punctiform spots were mainly in the sites of junction between costal cartilage and rib and frontal ribs, also mainly due to costal fractures (42/61, 68.85%). The majority of spots in strip shape were costal metastases(18/19, 94.74%). Hot spots in posterior ribs were also mainly costal metastases (24/29,82.76%). Conclusion Useful imaging features can be obtained from BS with al diagnosis of benign and malignant lesions.

Objective To investigate the effects of substrate stiffness on the proliferation of human umbilical vein endothelial cells ( HUVEC) during dengue virus infection.Methods Polyacrylamide gels were prepared for cell culture [(0±4) kPa].The proliferation of HUVEC cultured on substrates with differ-ent stiffness was determined by using 3-(4,5-diethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfo-phenyl)-2H-etrazolium,inner salt ( MTS) assay.The cycle and apoptosis of HUVEC were determined by flow cytometry analysis.Dengue virus serotype 2 (DENV-2) strains were propagated and identified by con-ventional assays.The HUVEC were infected with DENV-2 strains at a MOI of 10 and cultured on traditional plastic and hydrogel substrates, respectively.The levels of nitric oxide (NO) and endothelin-1 (ET-1) were detected by nitric acid reductase assay and double antibody sandwich ELISA.Results Young′s modulus E value of the hydrogels was (3030 ±0.44) Pa.The proliferation of HUVEC and the expression of NO and ET-1 were enhanced along the increased substrate stiffness.However, no significant differences with the cell cycle and apoptosis were observed between cells cultured on different substrates.Conclusion The stiffness of substrates affected not only the proliferation of HUVEC, but also the release of cytokines during DENV-2 infection.The development of dengue fever was associated with the decreased secretion of vascular active substances as a result of blood vessel injury.The establishment of hydrogel substrates as the model of vascu-lar basement membranes might provide a new way for the in vitro investigation of the pathogenesis of DENV infection.
