Objective:To observe the clinical efficacy of acupuncture with medication for post-stroke depression.Methods:A total of 96 patients with post-stroke depression were randomized into an observation group and a control group,with 48 cases in each group.The control group was treated with oral fluoxetine hydrochloride capsules,and the observation group was treated with acupuncture on the basis of the treatment of the control group.After 6 months of treatment,the traditional Chinese medicine (TCM) symptom scores,and Hamilton depression scale (HAMD) component scores and total scores of the two groups before and after treatment were observed,and the clinical efficacy and adverse reaction rate were compared between the two groups.Results:The total effective rate was 95.8％ in the observation group and 83.3％ in the control group,and the difference between the two groups was statistically significant (P＜0.05).After treatment,the intra-group differences in TCM symptom scores and HAMD score of both groups were statistically significant (all P＜0.01).In the observation group,the scores of indifferent expression,emotional restlessness,and sentimentality in the TCM symptoms were statistically different from those in the control group (all P＜0.01).The scores of desperate factor and sleep disorder factor and total score in HAMD in the observation group were significantly different from those in the control group (all P＜0.01).The incidence of adverse reactions was 6.3％ in the observation group and 4.2％ in the control group,and the difference was not significant between the two groups (P＞0.05).Conclusion:Acupuncture plus medication is an effective method for post-stroke depression,and it can further improve the patient's bad mood.

In order to provide a reference and theoretical guidance of the evaluation of electronic medical record (EMR) and establishment of evaluation system in China, we applied a bibliometric analysis to assess the application of methodologies used at home and abroad, as well as to summarize the advantages and disadvantages of them. We systematically searched international medical databases of Ovid-MEDLINE, EBSCOhost, EI, EMBASE, PubMed, IEEE, and China's medical databases of CBM and CNKI between Jan. 1997 and Dec. 2012. We also reviewed the reference lists of articles for relevant articles. We selected some qualified papers according to the pre-established inclusion and exclusion criteria, and did information extraction and analysis to the papers. Eventually, 1 736 papers were obtained from online database and other 16 articles from manual retrieval. Thirty-five articles met the inclusion and exclusion criteria and were retrieved and assessed. In the evaluation of EMR, US counted for 54.28% in the leading place, and Canada and Japan stood side by side and ranked second with 8.58%, respectively. For the application of evaluation methodology, Information System Success Model, Technology Acceptance Model (TAM), Innovation Diffusion Model and Cost-Benefit Access Model were widely applied with 25%, 20%, 12.5% and 10%, respectively. In this paper, we summarize our study on the application of methodologies of EMR evaluation, which can provide a reference to EMR evaluation in China.

The high molecular weight glutenin subunits (HMW-GS) are the main components of storage proteins of wheat,and play a critical role in determining the visco-elastic properties of gluten. There are both quantitative and qualitative effects of HMW-GS on the processing properties of wheat. Current knowledge of the molecular structures,compositions and properties of the gluten proteins of wheat is summarized in details,and the role of the HMW-GS in determining the quality of the grain for breadmaking and how their amount and composition can be manipulated leading to changes in dough mixing properties is also discussed systematically.

Reverse transcriptase-PCR experiments suggest that the two clusters of genes potentially involved in the oxidation of reduced sulfur compounds are organized as operons in strain of the acidophilic, chemolithoautotrophic bacterium Acidithiobacillus ferrooxidans ATCC 23270, the two clusters of genes including such the ORF of putative sulfate-thiosulfate-molybdate binding proteins, the ORF of putative thiosulfate: quinone oxidoreductase and the ORF of the rhodanese-like protein (P21). Bioinformatic analyses have predicted the possible promoters sequences and the possible +1 start site of transcription for the doxDA operons.

Background and Objective Keshan disease is clinically characterized as a dilated eardiomyopathy. We analyze the prevalence trend during last decade of hypertension and Keshan-disease in Yangzhuang village which was a Keshan-disease epidemic area.Method The survey including medical history,blood pressure and ECG were carried out every two years during the follow up 13 years.Results During follow up period,the total detection rate(hypertension:13.4 % vs Keshan-disease:10.7 %,?~2=8.555,P=0.002)and the accumulative rate of hypertension were higher than those of Keshan-disease,which was on the contrary to that before 1993,when increasing rate of Keshan-disease was higher than hypertension.Furthermore,the accumulative increasing rate of hypertension was 240.0%,which was higher than the national average level during corresponding period with no significant differences between female and male.Conclusion The detection rate of hypertension in Keshan disease epidemic area was higher than the average rate nation-wide.Whether the hypertension prevalence was re- lated to Keshan-disease needs further investigation.

Objective To determine whether a prophylactic tolterodine administration before surgical operation on non-urologic patients under general aneathesia can prevent the occurrence of catheter-related bladder discomfort (CRBD) ; and to assess patients’ tolerance to the symptoms as well as the impact on related consultation work of urologic surgeons.Methods One hundred and eighty cases of non-urology patients who need general aneathesia operations were divided into 2 groups:90 cases in tolterodine group and 90 in control group.The assessment of CRBD is categorized into 4 steps and statistics for adverse events ( dry mouth,dizzyness and facial flushing) was also conducted.A record of the patients’ needs for urologic surgical consultation during their reservation of catheter was also kept.SPSS 13.0 used in the statistical analysis of data in terms of X2 examination,where the divergence P ＜ 0.05 was regarded statisticly valid.Results 82 cases were followed up in the tolterodine group with a 24.4％ CRBD occurrence,which included 7.2％ shows moderate and severe symptoms,and there were also 23 cases with dry mouth ( 28.0％ ),4 cases with dizzyness (4.8％),13 cases with facial flussing ( 15.8％ ),and 1 case who needs further consultation (1.2％).In the 86 followed-up cases in control group,CRBD occurance rate was 54.7％,with 30.2％ showed moderate and severe symptoms,plus 2 cases suffered from severe consequences.Nine cases ( 10.5％) in control group requires further consultation ( X2 =19.499,P =0.000 ＜ 0.05 ).Conclusions A prophylactic tolterodine administration before surgery to the patients underwent general aneathesia can prevent the occurrence ofcatheter-related bladder discomfort (CRBD) and reduce the consultation work of urologic surgeons.Patients using tolterodine show a higher rate of adverse events,yet to which most patients can tolerate.

To explore the role of the Chk2 protein expression and DNA double strand breaks (DSBs) repair in low dose hyper-radiosensitivity (HRS)/increased radioresistance (IRR) of non-small cell lung cancer, A549 cells were subjected to irradiation at the dosage ranging from 0.05-2 Gy. Clonogenic survival was measured by using fluorescence-activated cell sorting (FACS) plating technique. Percentage of cells in M-phase after low doses of X-irradiation was evaluated by phospho-histone H3-FITC/PI and Western blotting was used to detect protein expression of Chk2 and phospo-Chk2. DNA DSBs repair efficiency was also measured by induction and persistence of γ-H2AX. The results showed that the killing ability of irradiation with A549 cells increased at low conditioning dose below 0.3 Gy. Within the dose of 0.3 to 0.5 Gy, A549 cells showed a certain extent of radiation resistance. And when the dose was more than 0.5 Gy, survival fraction exhibited a negative correlation with the dosage. There was no difference between the 0.1 or 0.2 Gy dosage groups and the un-irradiated group in terms of the percentage of cells in M phase. But in the high dosage group (0.3-1.0 Gy), the percentage of cells in M phase was decreased markedly. In addition, the percentage of cells in M phase began to decrease two hours after irradiation. One hour after irradiation, there was no conspicuous activation of Chk2 kinase in 0.1 or 0.2 Gy group, but when the irradiation dose reached 0.3 Gy or higher, Chk2 kinase started to be activated and the activation level showed no significant difference among high dosage groups (0.4, 0.5, 1.0 Gy). Within 1 to 6 h, the DNA DSBs repair efficiency was decreased at 0.2 Gy but increased at 0.5 Gy and 1.0 Gy, which was in line with Chk2 activation. We are led to conclude that the mechanism of HRS/IRR in A549 cell line was probably due to early G(2)/M checkpoint arrest and enhanced DNA DSBs repair. In this regard, Chk2 activation plays a key role in G(2)/M checkpoint activation.

Although current synthetic anti-gout drugs have significant therapeutic effects in reducing serum uric acid levels, they have serious side effects such as allergic reactions and liver and kidney damage. Natural products with a wide range of uric acid-lowering and high safety have played a critical role in anti-gout drug discovery and development. This paper reviews the natural products with uric acid-lowering or anti-gout pharmacological effects and the investigation on their mechanisms of action, to provide information for drug discovery and development.
