Objective To explore the clinical efficacy and safety of progesterone combined with Tiaojinghuoxue tablets in treating amenorrhea induced by antipsychotic drugs. Methods Total 100 patients were randomly divided into treatment group treated by progesterone combined with Tiaojinghuoxue tablets and progesterone group. The index including prolactin (PRL), luteinizing hormone (LH), estradiol (E2), endometrial thickness were measured before and after treatment in both groups . Also the clinical efficacy of the twogroups were compared. Results PRL, LH, E2, endometrial thickness and the recovery of menstrual flow rates in combination group were all better than the progesterone group, (P<0.05 or P<0.01). Cure rate in the combined group was 54.00%and the control group was 74.00%(P<0.05). Total effective rate of combined group was 90.00%and the control group was 80.00%(P>0.05). The rate of adverse reactions in combined group was 40.00%, less than 22.00%in progesterone group, (P<0.05). Conclusion The efficacy of progesterone combined withTiaojinghuoxue tablets is better than single progesterone treatment and have fewer adverse reactions in therpy antipsychotics drug induced amenorrhea.

Objective To understand the characteristics and related factors of adverse reactions (ADR) of anti-tuberculosis drugs among Zhuang nationality patients with smear-positive pulmonary tuberculosis (TB) and to provide basis to ADR control.Methods During Dec 2007 to May 2008,408smear-positive pulmonary TB cases of Zhuang nationality in 14 counties were selected by simple random sampling,and followed up for 6-8 months.Questionnaires were performed and liver/renal functions were tested during the research.Data were analyzed by chi square test and Logistic regression model.Results The incidence of ADR of Zhuang nationality people was 17.2％,which was higher than national level ( 12.62 ％ ).The incidence of allergic reaction was highest of all ADR ( 5.9 ％ ) and the incidences among different types of ADR were significantly different ( x2 =36.9,P=0.000).Serious ADR types were allergic reaction,gastrointestinal reaction,liver damage,nerve damage and kidney damage.And 24.3 ％ of the cases had two or three kinds of ADR.ADR occurred at the median of 21.5th day of anti-TB treatment,and the gastrointestinal reaction occurred the earliest (6th day).81.4 ％ of the ADR occurred in the first 2 months of anti-TB treatment.The rates of drug withdrawal and interruption were 11.5 ％ and 9.2 ％,respectively.Liver damage and nerve damage were the main causes of treatment withdrawal and interruption.Multiple factor non-conditional Logistic regression analysis showed that the ADR was correlated with age and the risk of ADR in ≥60years old patients was 3.3 times of that in 14-34 years old patients (OR=3.275,P=0.006).Thus,ADR incidence was increased with aging.Conclusions The incidence of ADR is higher in Zhuang nationality patients than that in general patient population.ADR monitoring and intervention must be strengthened in high-risk groups during high-risk period to reduce the adverse effect of anti-TBtreatment.

Objective To evaluate the effect of long-term glucocorticoid administration on nondepolarizing muscle relaxants-induced neuromuscular blockade in rat diaphragma in vitro.Methods Forty adult male SpragueDawley rats,aged 8 weeks,weighing 180-220 g,were randomized into 2 groups (n =20 each):control group (group C) and dexamethasone group (group D).In group D,dexamethasone 0.6 mg/kg was injected intraperitoneally once a day for 14 consecutive days,while the equal volume of normal saline was injected instead of dexamethasone in group C.The left phrenic nerve-hemidiaphragm was removed at 24 h after the last injection to evaluate the effect of d-tubocurarine.Different concentrations (0-10 μmol/L) of d-tubocurarine were added.The d-tubocurarine concentration-effect curve was drawn.The half inhibitory concentration and 95 ％ confidence interval of d-tubocurarine were calculated.Right diaphragma was removed for determination of the expression of embryonic nicotinic acetylcholine receptor (nAChRγ) mRNA and adult nicotinic acetylcholine receptor (nAChRε) mRNA by RTPCR.Results Compared with group C,the concentration-effect curve was shifted to the right,the half inhibitory concentration was significantly increased,and the expression of nAChRγ mRNA and nAChRε mRNA was up-regulated in group D (P ＜ 0.05).Conclusion Long-term glucocorticoid administration can weaken nondepolarizing muscle relaxants-induced neuromuscular blockade in rat diaphragma in vitro,and up-regulation of nAChR mRNA expression may be involved in the mechanism.

The growth and development of plant is affected by environmental factors that include light,temperature and water. Many cis-elements that are response to these elicitors interact with transcription factors, and regulate the expression of target genes. It concludes by pointing out recent studies of cis-elements and transcription factors in the plant environmental response promoters, such as light, temperature and water inducible promoter. The molecular mechanisms of gene expression regulated by environmental factors was discussed. This is important to study the mechanisms that plant adapt the environment.

Objective To explore the causes of rising carbapenem resistance in Acinetobacter baumannii isolates by analysis of the carbapenemase genotypes in A .baumannii .Methods WHONET 5 .4 was used to analyze the changing resistance profile of A .baumannii isolates over years .A total of 320 carbapenem‐resistant A .baumannii isolates were collected from the patients in an intensive care unit from January 2008 to December 2012 .All strains were identified and tested by VITEK 2 for their susceptibility .The metallo‐β‐lactamases genes and OXA carbapenemase genes were investigated by polymerase chain reaction . Results The resistance rate of A .baumannii isolates to meropenem and imipenem increased rapidly from 10 .8% to 80 .4% and from 13 .5% to 83 .5% during the period from 2008 and 2012 .The prevalence of blaOXA‐23and ISAba1‐associated blaOXA‐23genes increased from 25 .0% to 97 .1% .No metallo‐β‐lactamase encoding genes were detected .Conclusions Our results indicate that the rising carbapenem resistance in the A . baumannii isolates in our intensive care unit may be associated with the high prevalence of blaOXA‐23 and IS A ba1‐associated blaOXA‐23 genes .
