Objective:To develop the attitudes toward gay men and lesbians in Chinese context.Methods:Based on the sex differences in homosexual researches and the three factors of attitude,the initial Scale included two subscales of gay men and lesbians,and selected items from cognition,emotion and behavior;used the initial scale firstly to test 353 college students,then selected items through 4 methods;secondly,investigated 404 college students and 533 community residents with the ultimate scale in order to assess it in reliability and validity,10 days after the first testing session,193 students were re-tested.Results:Developed the attitudes toward lesbians and gay men scale of 20 items;the test-retest coefficients of total-scale was 0.959,the Cronbach's ? coefficient of the total-scale was 0.898,the split-half reliability was 0.912.Factor Analysis indicated there were three components in the scale including moral judgement,emotional reaction,and social communication.Conclusion:The attitudes toward lesbians and gay men scale has a high reliability and a good validity and can be used in researches of the public Attitudes toward homosexual.

Referring to the rapid developed life science and the higher requirements for the approval of innovative Chinese drugs in recent years, this paper described systematically the discovery, research and development (R&D) approaches for the innovative Chinese drugs under the new situation from the following five aspects, i. e., active components discovered from TCMs, the discovery of effective fractions of TCMs and their formulae, the R&D of TCM innovative drugs based on famous classic prescriptions and famous Chinese patent drugs, and the transformation of clinical effective prescriptions, on the basis of analysing the advantages of innovative drugs derived from natural products based on TCM theories and the problems existed in current R&D of new TCM drugs. Moreover, five suggestions are also given for the rapid development of TCM innovative drugs in China. All these will provide reference for the R&D of TCM innovative drugs.

ObjectiveTo investigate the genomic and non-genomic effects of 17β-estradiol on gallbladder smooth muscle strips of guinea pig and their possible mechanism. MethodsAfter ovariectomized operation (OVX) and subcutaneous injection of 17β-estradiol, the contents of serum estradiol and cholecystokinin-octopeptide (CCK-8) of the sham operation group (Sham) guinea pigs, the OVX group, the OVX and subcutaneous injection 17β-estradiol for 1 day (OVX+E2, 1 d), 3 days (OVX+E2, 3 d) and 7 days (OVX+E2, 7 d) were detected by EILSA respectively. The effects of CCK-8/Ach on constriction of gallbladder muscle strip were observed among various groups by using tension transducer, and the acute effects of 17β-estradiol on guinea pig gallbladder smooth muscle strips were observed to probe its possible mechanism. ResultsCompared with the Sham group, the serum contents of estradiol and CCK-8 decreased in OVX group (P＜ 0. 05) whereas the sensitivity of OVX guinea pigs gallbladder muscle strips to CCK-8/Ach increased (P＜0.05). With the extension of the subcutaneous injection 17β-estradiol time (for 1, 3, 7 days), both the serum estradiol and CCK level increased (P＜ 0.05) while the guinea pig gallbladder strips sensitivity to CCK-8/Ach decreased (P＜0.05).17β-estradiol at concentration ranging from 10 9 to 10-7 mol/L have no effect on the guinea pig gallbladder strips contraction (P＞0.05), but at concentration of 10-6 and 10 5 mol/L, it can inhibit the gallbladder contraction (P＜0.05). The blocking agents, such as nimodipine, atropine, devazepide, ICI 182,780 and Y-27632, can block the inhibited effects of 17β-estradiol. ConclusionThe 17β-estradiol can affect the gallbladder motility, both by genomic and non-genomic pathway.

Objective To explore the effect of biliary obstruction caused acute acalculous cholecystitis (AAC) on ultrastructure of gallbladder interstitial cells of Cajal (ICCs),and the possible mechanism of impaired contraction of gallbladder smooth muscle. Methods Total 60 healthy adult guinea pigs were in this study. The guinea pigs AAC model was induced by common bile duct ligation (BDL). The guinea pigs were divided into five groups equally,including sham control group (Sham),BDL for 12 hours (BDL-12),24 hours (BDL-24),48 hours (BDL-48) and 72 hours (BDL-72)groups. The gallbladder specimens were collected by the end of study. Gallbladder pathological changes were observed with HE staining under light microscope. Three muscle strips were collected of each gallbladder,fixed in constant temperature water bath with different concentration of eight peptide cholecystokinin agonist (CCK-8,1010 mmol/L,10-9 mmol/L,10-8 mmol/L,10-7 mmol/L and 10-6mmol/L),acetylcholine (Ach,10-8 mmol/L,107 mmol/L,10-6 mmol/L,10-5 mmol/L,10-4 mmol/L)and potassium chloride (KC1) (60 mmol/L). The contraction activity of gallbladder muscle strips was recorded by tonotransducer. The ultrastracture changes of gallbladder ICC in sham,BDL-12 and BDL-72 groups was examined by transmission electron microscopy. Results There was no obvious inflammation in Sham and BDL-12 groups. Compared with sham group,there were significant differences of biology score of gallbladder in BDL-48 and BDL-72 groups (P＜0. 05). After adding CCK-8,Ach and KC1,the contraction amplitude of gallbladder muscle increased in each group,and in dose-dependent manner. Compared with sham group,the effect value of each other groups decreased significantly (P＜0. 05). Compared with sham group,the morphology of ICC changed in BDL-12group,and more obvious in BDL-72 group. Conclusion Biliary obstruction can induce AAC. At the earlier stage of ACC,the impaired contraction of gallbladder smooth muscle present even without gallbladder inflammation occurrence. ICC may play an important role in impaired contraction.

With constant development and application of new generation information technology such as big data, cloud computing and Internet of Things, traditional management style and thought patterns of TCM are being changed. It is particularly important to introduce information security into budget management of TCM projects. This article discussed security factors in TCM budget monitoring platform, organized key contents of information security construction, built information security model for monitoring platform, and analyzed security strategies for the construction of TCM budget monitoring platform, with a purpose to guarantee effective implementation of budget information management measures of TCM projects.

Objective To explore the risk factors for asthma in children.Methods A 1:1 matched and hospital-based case-control study was conducted to analyses risk factors for asthma in 300 pairs of children by logistic regression analysis. Results The result of univariate Logistic regression analysis showed that there were 17 related factors for children asthma, including disease history of parents in respiratory system,family income,atopie character,history of acute respiratory infections, eating habit,the amount of sea foods intakes,foam plastics,family decoration,the way of exhaust fume in kitchen,the exhaust effectiveness,raising pet in house,family history of asthma,family history of allergic rhinitis,family history of food allergy,dust allergy of parents,systemic therapy after the first attack.With multivariate Logistic regression analysis,7 factors were entered the model,6 risk factors including father's history of respiratory diseases(OR 3.771,95%CI 1.533～9.278),low family income(OR 1.503, 95%CI 1.258～1.795),atopy(OR 3.788,95%CI 2.368～6.058),meat-eating habit(OR 2.042,95%CI 1.481～2.815),asthma history of family members(OR 1.710,95%CI 0.988～2.958),the family history of allergic rhinitis(OR 1.991,95%CI 1.234～3.211), and 1 protective factor of raising pet in house(OR 0.443,95%CI 0.265～0.739).The coefficients of these factors in multivariate logistic regression model were 1.327、0.407、1.322、0.714、0.536、0.689、and-0.814 respectively.Conclusion Children asthma was a multi-factorial complex disease,and the interaction of environmental and genetic risk factors played an important role in the onset of this disease.
