ObjectiveTo investigate the effect of repeated transfer of liposome mediated CD gene plus radiation on the growth of human rectal cancer cells xenograft in nude mouse Methods HR 8348 cells transfered with liposome mediated CD gene repeatedly (at day 0,4,8,12 ) and treated with fractionated radiation at a dosage of 2 Gy/day to a total dose of 30 Gy. At the same time, mice were injected i.p.with 800 mg/kg/day of 5 FC for 12 days. Results Compared with controls tumors in treatment group grew with an inhibition rate of 78 7% in weight, and 81 5% in volume. ConclusionRepeated transfer of liposome mediated CD gene working together with radiation effect a significant inhibition on the growth of xenografted human rectal carcinoma HR 8348 cells in nude mouse.

OBJECTIVE To provide the investigative data for timely changing medical gloves according to the study on the dynamic change of physical property of the gloves during abdominal open procedure.METHODS The gloves used in the abdominal open procedures were collected.The tensile strength,break elongation and the morphological values of three types of the gloves(No.6.5,7 and 7.5) were measured and recorded before and after their using at the time point of 0.0h,1.5h,2.5h,3.5h,4.5h,5.5h and 6.5h during operation.RESULTS The tensile strength decreased significantly(P

Twenty-seven ERF transcription factor family genes were isolated from Arnebia euchroma, with an average size of 1,010 bp, each gene encoded a 212 amino acids on average. The gene structure and expression of physicochemical properties, subcellular localization, signal peptides, senior structural domains and conservative forecasting, and analysis of A. euchroma were studied comparing with ERF gene gi261363612 of Lithospermum erythrorhizon, and phylogenetic analysis of A. euchroma ERF family was carried out. The results showed the existence of three conserved domains in this family, the senior structure based on random coil and it clustered into CBF/DREB and ERF subfamilies.

OBJECTIVETo critically assess the quality of literature about systematic review or meta-analysis on traditional Chinese medicine (TCM) published in Chinese journals.

METHODSElectronic searches in CNKI, VIP and Wanfang data-base were conducted to retrieve the systematic reviews or meta-analysis reports on TCM, including herbal medicine, needling, acupuncture and moxibustion, as well as integrative medicine, they were identified and extracted according to the 18 items of QUOROM (quality of reporting of meta-analyses) Statement and relative information. The appraisal was made taking the indexes mainly including objectives, source of data, methods of data extraction, quality assessment of the included studies, measurement data synthesis, etc.

RESULTSEighty-two systematic reviews were identified, except 6 reviews were excluded for repeatedly published or didn't comply with the enrolled criterion, 76 reviews concerning 51 kinds of diseases were enrolled for appraisal. Among them, 70 reviews evaluated the efficacy of TCM, mainly on Chinese herbs and 9 on acupuncture and moxibustion. In majority of the reviews, randomised controlled trials were included and the data resources were described, but in 26 reviews only the Chinese databases were searched and the description about data extraction and analysis method were too simple; and 70% of reviews assessed the quality of the included studies; none used flow chart to express the process of selection, inclusion and exclusion of studies.

CONCLUSIONSFew reviews or Meta-analysis reports reached the international standard and there is insufficient description of methodology for conducting systematic reviews, so it is hardly to be repeated. The authors suggested that advanced methodological training is necessary for reviewers.

OBJECTIVE To establish and optimize the detection of highly pathogenic influenza virus H5N1 subtype by RT-Multiplex (RT-M) PCR method. METHODS The viral RNA was reversely transcripted with universal primer,and the cDNA was sequenced and analyzed. According to the cleavage site of H5 and the conservative sequence of N1,designed two pairs of specificity primer,RT-M PCR was developed by these primers. Then verified the sensitivity of method and its specificity by detecting comparing with NDV,IBV and IBDV. RESULTS The results of H5N1 gene sequence showed the high homology with the Anhui H5N1 strain [avian influenza A/Anhui/1/2005 (H5N1)] after comparing in the GenBank. Two fragments of 302 bp and 567 bp were amplified by RT-M PCR. The method could detect 0.500 pg virus RNA at least,and own high specificity. CONCLUSIONS This method can be used for highly pathogenic avian influenza.

Objective To explore the rehabilitation needs and its influential factors of adults with physical disability in Shanghai, and to provide evidence for decision-making of the precise rehabilitation service. Methods From November to December, 2016, the rehabilitation demands, utilization rate and its influential factors of 390 registered people with physical disability were investigated with a questionnaire. Results The service of occupational rehabilitation met 62.34%and educational rehabilitation met 52.00%of the needs of adults with physi-cal disability at the age of 18 to 40 years. The service of occupational rehabilitation met 38.71%and educational rehabilitation met 35.29%of the needs of adults with physical disability of grade two. The main obstacle to the service utilization wasDo not know(67.34%). As a part ofotherreason, the cumulative frequency oftemporarily not neededaccounted for 16.41%in all reasons. Conclusion The rehabili-tation service should focus unmet needs to complete the community rehabilitation and health governance, and optimize the service system.

OBJECTIVETo establish a rapid quantitative analysis method for the content of chlorogenic acid and solid content in the extraction liquid concentration process during the production of Reduning injection by using the near-infrared (NIR) spectroscopy, in order to reflect the concentration state in a real-time manner and really realize the quality control of concentrating process of the extraction and concentration process.

METHODThe samples during the Jinqing extraction liquid concentration process were collected. After the removal of abnormal samples, the spectra pretreatment and the wave band selection, the quantitative calibration model between NIR spectra and chlorogenic acid HPLC analytical value and solid content was established by using PLS algorithm, and unknown samples were predicted.

RESULTThe correlation coefficients between the chlorogenic acid content and the solid content were respectively 0.992 1 and 0.994 0, and the correlation coefficients of the verification model were respectively 0.994 4 and 0.998 4, with the root mean square error of calibration (RMSEC) of 0.814 6 and 2.656 1 and the root mean square error of prediction (RMSEP) of 0.704 6 and 1.876 7 respectively, and the relative standard errors of predictions (RSEP) were 6.01% and 2.93% respectively.

CONCLUSIONThe method is simple, rapid, nondestructive, accurate and reliable, thus could be adopted for the fast monitoring of the chlorogenic acid content and the solid content during the concentration process of Reduning injection extraction liquid.
