OBJECTIVETo explore the role of traditional Chinese medicine (TCM) syndrome scores in effectiveness evaluation of clinical studies.

METHODSRandomized controlled trials (RCTs) of TCM published in five journals in 2013 were retrieved, including Journal of Traditional Chinese Medicine (JTCM), Chinese Journal of Integrated Traditional and Western Medicine (CJITWM), Chinese Journal of Integrative Medicine (CJIM), Evidence-Based Complementary and Alternative Medicine (ECAM), and American Journal of Chinese Medicine (AJCM). The details of TCM syndrome scores and other relevant factors reported in articles were extracted and analyzed. Descriptive statistics and Chi-square test were used to describe general features of inclusive studies, ratios of reports on CM syndrome scores in each journal, formulated evidence, adopted evaluation rules, important degrees. The difference in the application rate of CM syndrome scores were compared in various diseases, diseases with or without CM syndrome typing, places where clinical studies were implemented, and different journals.

RESULTSA total of 240 RCTs were included, involving 178 published in Chinese version and 62 in English version. CM syndrome scores were used for effectiveness evaluation in 27.1% (65/240) of RCTs, of which, the highest application percentage was 35.3% (18/51) in RCTs published in CJITWM, and the lowest was 0 (0/7) in RCTs published in AJCM. There were 17 methods for grading TCM syndrome scores, of which Guideline for Clinical Research of New Chinese Herbal Medicine was most commonly used. Detailed grading standards for CM syndrome scores were reported in 46 RCTs, and CM syndrome scores were taken as primary or secondary outcomes in 6 RCTs. When describing the percentages of RCTs adopting TCM syndrome score by diseases classification, the lowest was 9.5% (2/21) in mental and behavioral disorders, and the highest was 39.1% (9/23) in endocrine, nutritional, and metabolic diseases. RCTs with TCM syndrome differentiation had a higher percentage of adopting TCM syndrome score than those without TCM syndrome differentiation (P < 0.01). Statistical differences were also found among RCTs published in Chinese core journals (32.0%), domestic science citation index (SCI) journals (28.6%), and overseas SCI journals (4.9%) (χ2 = 12.4593, P < 0.01). For RCTs conducted by Chinese scholars, the percentage of using TCM syndrome score was 32.0% in three journals from China, while 7.1% in two foreign language journals, showing significant difference (χ2 =7.3615, P < 0.01); none of RCTs conducted by foreign scholars used TCM syndrome scores for effectiveness assessment.

CONCLUSIONSThere was a lack of agreeable and universal standards for TCM syndrome scores using in effectiveness evaluation. Therefore, it was not commonly used in domestic CM clinical studies. It was not so favorably agreed in overseas academic circles.

Objective To established a bacteriemia model of BALB/c mice after infection with a ST-239 methicillin-resistant staphylococcus aureus(MRSA) strain, which was isolated and identified from Shanghai Huashan Hospital. Methods We monitored the clinical signs and gross observations of MRSA-infected mice, and examined the histopathology among different groups. Results This isolated MRSA strain ST-239 can induced a typical bacteriemia in BALB/c mice, including the severe mortality and extensive histopathologic injury. However, higher survival rate and slight inflammatory injury were observed in vancomycin-treated mices. Conclusion The solid results obatined in this model will benefit us to study the pathogenic characteristics and patholgenesis in MRSA-induced bacteriemia, and propeled us to seek a safety cure approaches in the future.

In 2013 Shanghai took the lead to carry out the specialist standardized training which is common in the international medical education. This paper first gives a picture of the general condition of the standardized training on specialists of obstetrics and gynecology in Shanghai. Then from the perspectives of strategic deployment, department management, clinical skill training and the training of examiners, the paper explores the assessment model in which both the assessment of train-ing process and the scores of the final examination are considered whereas the process assessment is given more weight. This paper is aimed to provide experience and suggestions for the further advance of the specialists standardized training in the field of obstetrics and gynecology.

Good clinical practice should be based on evidence. Evidence quality should be based on critical appraisal in evidence based medicine (EBM). Evaluation of evidence quality plays an important role in evidence level clarifying, which is the core of EBM. Different recommendations for clinical practice often derive from evidence levels. Thus evidence quality evaluation is the first and most important step in EBM. There are lots of standards to evaluate evidence quality in the world. However there are two aspects of the evaluation, one is methodological evaluation and the other is reporting evaluation. This article collected a series of standards for clinical trials quality evaluation according to different research designs. It is hoped that the resource and introduction about the quality evaluation of clinical trials be helpful for medical researchers in China. Only being familiar with all kinds of standards of methodology and reporting, researchers could publish high quality scientific papers.

This paper was aim to optimize the purification technology of Rehmanniae Radix Praeparata extract with macroporous adsorption resin. With the content of manninotriose as index, the absorptive flow and time were investigated, as well as kinds, amount, flow of eluent. D-101 type macroporous adsorption resin was the best choice for the purification of manninotriose. The optimized parameters were as follows: the content of manninotriose at 161.16-53.72 mg x g(-1), absorption time 240 min, eluting solvent of purified water, volume flow at 1.5 BV x h(-1), and eluant volume at 6 BV. D-101 type macroporous adsorption resin could significantly increase the purity of Rehmanniae Radix Praeparata extract with the advantage of high absorption, remove most part of impurity, and the effect of semi-works production was better.

OBJECTIVE To investigate the countermeasures of preventing endophthalmitis in the process of large number of successive cataract phacoemulsification surgeries at the Lifeline-Express train.METHODS All measures of preventing postoperative endophthalmitis during and after cataract surgery procedures from Mar 2007 to Aug 2007 at the Second Lifeline-Express train were retrospectively analyzed and summarized.RESULTS There was not any postoperative endophthalmitis occurred from 2539 procedures of cataract phacoemulsification surgeries.CONCLUSIONS A series of the effective approaches as muticulous as possible are keys to prevent the postoperative endophthalmitis in the process of large number of successive cataract phacoemulsification surgeries.

To explore the prevalence of hepatitis B virus (HBV) in multiple myeloma (MM) patients, as well as to compare the clinical characteristics and outcome between HBV infected and non-HBV infected patients. Methods:The serology markers of HBV were detected in 363 MM patients and 11227 cases of healthy controls through chemiluminescence. HBV-DNA was measured via real-time quantitative chain reaction. Results:Sixteen out of 363 MM patients (4.4%) were HBsAg-positive, showing significant difference with healthy controls (2.4%). No statistically significant differences were observed in terms of sex, age, type of monoclonal (M) protein, International Staging System (ISS) stage, stem cell transplantation, and risk stratification between HBsAg-positive and HBsAg-negative patients. No significant effect of HBV infection was found on the OS of MM patients. HBV reactivation was observed in two HBsAg-positive MM patients who were treated with combination chemotherapy, including bortezomib and dexamethasone. The replication of HBV could be inhibited by anti-HBV drugs. Conclusion:A higher prevalence of HBV infection was revealed in MM patients. Close monitoring of HBV replication should be conducted in MM patients with HBV infection before and during the courses of chemotherapy.

Objective: To summarize the experience for treating pulmonary venous obstruction in patients after total anomalous pulmonary venous connection (TAPVC) operation. Methods: A total of 16 patients with post-TAPVC pulmonary venous obstruction in our hospital from 2011-01 to 2015-12 were retrospectively analyzed including10 male. All patients received echocardiography, electrocardiogram and chest X-ray examinations at pre-discharge, 1, 3, 6, 12 and 24 months post-operation. Pulmonary venous obstruction was diagnosed by echocardiography measured pulmonary vein (PV) lfow speed>2m/s. The time of re-operation was determined by clinical manifestations as recurrent heart failure and growth retardation; sutureless technique and conventional patch enlarge technique were used in the second operation. Results: No one lost contact in all 16 patients. There were 7/16 patients with anastomotic stenosis (1 mixed type, 3 infracardiac type, 2 supracardiac type and 1 cardiac type), 7 patients with one PV stenosis, 2 with two PV stenosis and nobody with three or more PV stenosis. Based on per-operative Darling classiifcation, there were 2 patients with mixed type, 5 with infracardiac type, 5 with supracardiac type and 4 with cardiac type. Most post-operative PV stenosis occurred at 3-6 months after the surgery. There were 5 patients receive re-operation, 4 with sutureless technique, 1 with conventional patch enlarge technique and all of them suffered from anastomotic stenosis. 2 patients died and 3 were followed-up. Conclusion: Post-operative anastomotic stenosis was the main indication for re-operation in patients after TAPVC; early operation could better improve the clinical condition.
