Textual research on ancient and modern literature and analysis on research hot spots of classical prescription Shenling baizhu powder / 中国药房

OBJECTIVE To provide reference for the clinical application and further research and development of Shenling baizhu powder. METHODS Using the methods of textual research and bibliometrics， the key information such as the composition， dose， processing and usage of Shenling baizhu powder in ancient and modern literature were systematically summarized and sorted out， and the number of publications， keywords， and other contents of modern literature were visually analyzed. RESULTS & CONCLUSIONS Shenling baizhu powder was first collected in Taiping Huimin Hejiju Fang （abbreviated “Jufang”）， the composition of core drugs and most widely used dose ratio in previous generations were the same as those in Jufang， basically focusing on powder making and being taken after mixed with liquid； the dosage was concentrated on 2-3 qian； the function and application of it had been expanded to a certain extent compared with Jufang； its clinical application had gradually extended from internal medicine to surgery， gynecology， pediatrics， ophthalmology， dermatology， etc.， covering all aspects of the disease caused by spleen deficiency in general； the composition mechanism revolved around “strengthening the spleen， replenishing qi and removing dampness”； the recommended prescription drugs were all selected from the corresponding varieties in the pharmacopoeia. Modern research mainly focuses on clinical practice， with traditional Chinese medicine or traditional Chinese and Western medicine combined with this formula as the main modified treatment for various intestinal diseases， diarrhea diseases， and lung diseases. The efficacy and application are the frontier hot spots today， and the mechanism of action has begun to be explored. The usage in the literature and the inclusion in the pharmacopoeia are inconsistent， and further research is needed.

The distribution and drug resistance of pathogens of blood stream infection in pediatric surgery intensive care unit / 中国小儿急救医学

Objective To identify the pathogen distribution and antibiotics resistance of blood stream infection(BSI) in the pediatric surgery intensive care unit(PSICU).Methods The clinical data of 138 pediatric patients diagnosed with BSI from January 2011 to December 2015 were collected in PSICU,and the distribution of pathogens and drug resistance were retrospectively analyzed.Results The incidence of BSI was 3.88‰(138/35.524)in the five years,the majority of the BSI cases occurred under one year old,and the mortality was 13.77%(19/138).A total of 179 strains were isolated from blood samples of 138 patients,of which gram-positive bacteria,gram-negative bacteria and fungi accounted for 60.89%(109/179),22.91%(41/179)and 16.20%(29/179)respectively.The most common gram-positive bacteria was coagulase-negative staphylococcus (84/179,46.93%).The predominant gram-negative bacteria were Acinetobacter baumannii(15/179,8.38%),Klebsiella pneumonia(12/179,6.70%) and Escherichia coli(6/179,3.35%).The rate of carbapenems-resistant Acinetobacter baumannii increased continuously in the study period.Non-albicans Candida was the most common fungi (14/179,7.82%).The resistance rate of multi-drug resistant strains to carbapenems significantly increased.Conclusion The incidence of BSI in PSICU increases,and the mortality in children younger than one year is high.Better understanding of distribution of BSI pathogen could provide more effective antibiotic prescription.

Effects of miR-21 on the Proliferation,Apoptosis and MMP2 Expression of HeLa Cells / 中国医科大学学报

Objective To study the effects of miR?21 on the proliferation,apoptosis and MMP2 expression of HeLa cells. Methods The miR?21 or the miRNA scramble control was transfected into Hela cells. The cell proliferation was detected by the Celltiter?GloTM assay 72 h after the transfection,and the apoptosis was evaluated by the Caspase3/7 Glo? Kit. The MMP2 RNA expression was quantified by quantitative real time PCR. Results The proliferation of HeLa cells transfected with miR?21 was significantly increased compared to that of the cells transfected with miRNA scramble control. The caspase 3/7 activity in HeLa cells transfected with miR?21 was downregulated compared to that of the cells transfect?ed with miRNA negative control. The MMP2 RNA expression in HeLa cells transfected with miR?21 was increased significantly compared to the cells transfected with miRNA negative control. Conclusion miR?21 can significantly promote the proliferation of HeLa cells. In addition,it ex?hibits the anti?apoptosis effect in HeLa cells. The transfection of miR?21 significantly increased the MMP2 RNA expression,which suggests that miR?21 may promote the tumor invasion and might be a therapeutic intervention target.

Construction of the first genetic linkage map of Salvia miltiorrhiza Bge. using SSR, SRAP and ISSR markers / 药学学报

The first genetic linkage map of Salvia miltiorrhiza was constructed in 94 F1 individuals from an intraspecific cross by using simple sequence repeat (SSR), sequence-related amplified polymorphism (SRAP) and inter-simple sequence repeat (ISSR) markers. A total of 93 marker loci in the linkage map, consisting of 53 SSR, 38 SRAP and 2 ISSR locus were made up of eight linkage groups, covered a total length of 400.1 cm with an average distance of 4.3 cm per marker. The length of linkage groups varied from 3.3 -132 cm and each of them included 2-23 markers, separately. The result will provide important basis for QTL mapping, map-based cloning and association studies for commercially important traits in S. miltiorrhiza.

Coronary heart disease: incidence, risk factors and interventions in Jiaozhou of Shandong province / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Coronary heart disease (CHD) is the most common type of heart disease and cause of heart attacks. This study investigated the epidemiological characteristics of CHD and its risk factors in Jiaozhou, Shandong province, to ultimately find a way of reducing the prevalence of cardiovascular disease, and to provide a theoretical basis for establishing a cardiovascular disease management path under the regional medical collaborative mechanism.</p><p><b>METHODS</b>A questionnaire survey was performed including 1 952 people aged 35 years or older who were questioned by means of stratified, cluster, proportional sampling to investigate the prevalence of CHD and its risk factors. The data were inputted into SPSS11.0 statistical software for processing and analysis. We advised the local medical institutions to establish health files for the residents with CHD and risk factors. They were followed up regularly. Their risk factors and life-style were monitored, and advice was given as to proper medications. Green channels were established, and the patients were transmitted in a timely manner to superior hospitals for better treatment if the necessary treatments were not available in the local hospitals. The control of risk factors was observed after the follow-up for half a year.</p><p><b>RESULTS</b>In Jiaozhou, the rates of coronary artery disease, hypertension, diabetes, hyperlipidemia and overweight were 8.15%, 28.54%, 11.43%, 35.46%, and 18.70% respectively. The rates of hypertension, diabetes, hyperlipidemia and overweight were higher than the data published in "The report of Chinese cardiovascular disease 2012"; which are 24%, 9.7%, 18.6%, and 9.7%, respectively. The control of risk factors improved significantly after the guidance of the residents lifestyle and medication for six months.</p><p><b>CONCLUSIONS</b>The high prevalence of coronary artery disease in Jiaozhou is closely related to age, gender, diet structure, family history of cardiovascular disease, hypertension, diabetes, hyperlipidemia, overweight, and unhealthy lifestyle. Under the regional medical coordination mechanism, the collaborative management of cardiovascular disease can provide new management concepts for the areas short of medical resources, so as to reduce the prevalence of cardiovascular disease.</p>
