Objective To probe into urban residents' mental health knowledge awareness in Jingmen city. Methods By means of self-compiled questionnaires, 563 community residents were surveyed about their mental health knowledge and access to it. Results For mental health- care knowledge, community residents scored a total of (42.52±8.79), among which, (15.34±3.25) points for relevant causes,(12.23±4.89) points for corresponding symptoms, and (14.92±4.26) for health behavior. Such aspects would affect a resident's awareness of mental health knowledge as the resident's education background,marriage and chronic diseases. Radio and television (48.3%), newspapers and magazines (41.4%), hospital expert advice (39.8%), and community medical services (36.1% ) were considered the better access to mental health knowledge. Conclusions Residents had considerably inadequate knowledge of mental health. Therefore, a variety of health- care education activities should be carried out to improve residents'mental health knowledge.

Protective effects of acupuncture on myocardial ischemia in each stage have been confirmed increasingly, while there was no in-depth research in terms of histone modifications. Histone modification is an important part of epigenetics. It is also the focus of molecular biology and basic medical research. In this paper, the relationship of histone modifications and gene expression of heart was first explained. Then, the recent research progress of modified histones, which was the direct alteration of gene expression induced by histone modifications on the degree and prognosis of myocardial ischemic injury, was reviewed. This investigation introduced epigenetic regulation in the protection mechanism of myocardial ischemia by acupuncture. It provided new ideas and directions for the study of molecular mechanism of acupuncture efficacy.

A novel method for DNA detection was developed based on the excellent fluorescence properties of cationic conjugated polymer ( CCP)and the target DNA enrichment,separation function of nanoparticles. First,the quencher-labeled DNA capture probes were modified on the surface of Au nanoparticles,and complementary DNA strands were captured. Second,S1 nuclease was added,and the capture probes that had not captured the complementary DNA were removed from the nanoparticles.Finally,the complementary double-stranded DNA was cut by Dnase I,the quenchers were dissociated from nanoparticle and the fluorescence of CCP was quenched by means of combination of quenchers and CCP.The results showed that this method is specific.In the range of 5. 0 -40 nmol/L,the concentration of target DNA was proportional to the fluorescence quenching and the detection limit was 3.7 nmol/L(S/N = 3).

OBJECTIVE To investigate the protective effect of total alkaloids of Rhizoma Corydalis (TARC) on experimental gastric mucosal lesions in rats. METHODS Gastric mucosal lesions were induced in rats by injecting acetic acid under gastric mucosal. From the 2nd day post the preparation of the rat model, cimetidine 400 mg · kg-1 or TARC 20, 40 and 80 mg · kg-1 was ig delivered for 15 d in different groups. Two days after the last delivery, gastric juice volume and total acidity were measured. Histopathology of stomach tissues was observed by HE staining. The area of gastric ulcer area was measured and the ulcer index and ulcer inhibitory rate were calculated. The expression of epidermal growth factor (EGF) and EGF receptor (EGFR) was detected by immunohistochemical staining. RESULTS Comparing with shame group, the eare of gastric ulcer and ulcer index were increased signifi?cantly in the model group(P<0.01), suggesting that the model rats were prepared properly. Compared with the model group, the ulcer area in rats of cimetidine and TARC 80 mg·kg-1 groups was decreased by 39.9%and 23.7%,respectively. The ulcer index was decreased by 52.3%and 30.5%,respectively. There was no significant difference between the cimetidine group and TARC 80 mg · kg-1 group, in the ulcer area or index. Compared with model group, EGF protein expression of cimetidine and TARC 40 and 80 mg · kg-1 groups was increased by 81.8%,24.2%and 57.6%,respectively while EGFR protein expression was increased by 45.9%,16.2%and 29.7%,respectively(P<0.05,P<0.01). Deciduous and necrotic gastric mucosal and a large amount of inflmmatory cells infiltration were observed in model group, and gastric mucosal lesions were improved in cimetidine and TARC 40 and 80 mg · kg-1 groups. CONCLUSION TARC has protective effect on gastric mucosal lesions in rats. The mechanism may be related to the increase of EGF and EGFR protein expression.

OBJECTIVETo observe the clinical efficacy on chronic stable angina pectoris treated with acupuncture at Neiguan (PC 6) and explore the impacts of acupuncture on peripheral blood neutrophil to lymphocyte ratio (NLR) in the patients of stable angina pectoris.

METHODSThirty patients of chronic stable angina pectoris met the inclusive criteria were randomized into an acupuncture group (15 cases) and a medication group (15 cases), and a healthy control group (15 cases of the same ages) was set up separately. In the acupuncture group, at the same time of the basic medication, acupuncture was applied to bilateral Neiguan (PC 6), once every two days, 3 days a week, totally for 4 weeks. In the medication group, the basic medication was applied, without acupuncture intervention. In the healthy control group, no any intervention was applied. The attack frequency of angina pectoris, dose of nitrogly-cerin, the evaluation of visual analogue scale (VAS), Seattle angina questionnaire (SAQ), the six-minute walking test (6MWT), the self-rating anxiety scale (SAS) and the self-rating depression scale (SDS) were observed before and after treatment in the subjects. Additionally, the peripheral blood cells were detected to analyze specifically the changes in NLR before and after treatment and observe the relationship between NLR and clinical efficacy.

RESULTSCompared with the medication group, the attack frequency of angina pectoris was reduced within 30 days (P<0.01); the dose of nitroglycerin was reduced (P<0.01); VAS was reduced (P<0.01) and SAQ was increased (P<0.05) in the acupuncture group. The differences in 6 MWT, SAS and SDS were not significant between the two groups after treatment (all P>0.05). Additionally, compared with the medication group, in 30 days of acupuncture, NLR was reduced apparently in the acupuncture group (P<0.05).

CONCLUSIONAcupuncture relieves the clinical symptoms of chronic stable angina pectoris, but has not apparent effects on motor ability and psychological health. Corresponding to that before treatment, the decreased NRL in the patients of acupuncture group suggests the potential good prognosis on coronary heart disease after acupuncture.

Medical claims database is an important source of data for studying the characteristics, and burden of diseases, to provide a basis for the development of policy on management. The database is usually used to identify patients through International Classification of Diseases and free text-building algorithms, thus it is crucial to validate whether the algorithm is correctly identifing the targeted population. This paper introduces both traditional and emerging validation methods including machine learning, natural language processing and database linkage etc.. We also have tried to present a suitable validation method for the current situation in China, so as to promote the application of big data in medical areas and to provide reference for epidemiology studies, based on medical claims database in this country.

A large amount of data has been accumulated in Chinese medical area. Problems as how to use big data to carry out randomized controlled trials have also been increasingly noteworthy. Through learning the successful experiences in conducting randomized controlled trials on big data from abroad, this article introduces the knowledge regarding sources of data, identification of research subjects and outcomes, interventions, methods of randomization and the implementation of informed consent, etc., all related to big data, hoping to shed light on studies of this kind, for the years to come in China.
