OBJECTIVETo analyze the current status of maternal HIV infection, mother to child transmission, and the work accomplishments in preventing mother-to-child transmission of HIV (PMTCT).

METHODSDuring October, 2001 to May, 2009, HIV voluntary consultation and examination were carried out in 339 866 pregnant women in the urban areas, while 594 pregnant women who tested positive were intervened, and interventions were also conducted among 326 babies who were born to HIV positive mothers, including HIV immune body examination on the babies when they were 12 months and 18 months old.

RESULTSA total of 594 pregnant women were found HIV positive, with the positive rate of 0.17% (594/339 866). And the rate was declining year by year. The highest rate was 0.47% (37/7837) in 2002, and the lowest rate was 0.12% (86/73 343) in 2008. Of the 594 positive pregnant women, 228 (38.38%) terminated pregnancy voluntarily, 43 (7.24%) kept on pregnancy and 317 (53.37%) parturients. Of 326 babies born by the 317 parturients, 317 survived.298 received curbing intervention for mother to child transmission (PMTCT), the ratio was 94.01% (298/317). Of 224 babies who were 18 months old, 221 accepted examination, and 7 HIV positive. The maternal infant transmission rate after intervention was 3.17% (7/221).

CONCLUSIONThrough the prevention of mother-to-child transmission of HIV, the HIV infection status in the pregnant women can be timely observed, which can effectively decrease the level of mother-to-child transmission of HIV.

Objective To detect the distribution of resistance-nodulation (RND)efflux pump system of Acineto-bacter baumannii (AB),and explore the relationship between its’expression and antimicrobial resistance.Methods Fifty-nine strains of multidrug-resistant AB isolated from clinical specimens in The First Affiliated Hospital of Nan-chang University were identified and performed antimicrobial susceptibility analysis,distribution of RND efflux sys-tem of AB was detected by polymerase chain reaction(PCR),expression of efflux pump genes in different drug-re-sistant phenotypes of AB was compared,relationship between the expression level and drug resistance was analyzed, amplified products of RND efflux system were sequenced.Results Resistance rates of AB to ampicillin/sulbactam, imipenem,gentamicin,ciprofloxacin,and levofloxacin were 93.2%,94.9%,88.1%,96.6%,and 52.5% respec-tively.PCR detection results of efflux pump and integron genes of 59 AB strains revealed that the carrying rates of adeR,adeS,adeB,adeJ,and adeG genes were 81.4%,91.5%,93.2%,100.0%,and 61.0% respectively.The expression of efflux pump genes in different strains was different,expression levels of ade B and adeJ genes among gentamicin,imipenem,ampicillin/sulbactam resistant AB group and non-resistant AB group were significantly dif- ferent (all P＜0.05).There was no mutation or insertion sequence in the base sequences of regulatory genes ade R and ade S of adeABC efflux pump.Conclusion RND efflux pump system is universally present in AB,the expres-sion upregulation of ade B and ade J genes in RND efflux pump system is related with antimicrobial resistance of bacteria to gentamycin,imipenem,and ampicillin-sulbactam.

OBJECTIVETo understand the prevalence and control of several common chronic disease in Beijing adults.

METHODS16,658 adult residents were randomly selected with stratified multi-stage cluster sampling method. Each participant was invited to receive a set of standardized questionnaire, physical examinations and laboratory tests.

RESULTSData showed that the prevalence, awareness, treatment and the rate of control on hypertension among the adults in Beijing were 29.1%, 49.3%, 42.3% and 10.6% respectively. The counterparts of diabetes mellitus were 8.8%, 56.7%, 50.0% and 15.0%. The four corresponding figures for dyslipidemia were 33.2%, 31.1%, 13.0% and 4.3%, respectively. 22.9% of the Beijing adults had metabolic syndrome including 8.1 per thousand suffering from myocardial infarction and 18.4 per thousand from stroke. Except for diabetes, all the chronic diseases had higher prevalence rate in rural area than in urban area, according to the findings under our study. Postmenopausal women were more susceptible to chronic disease than men.

CONCLUSIONThe prevalence rate of chronic disease in Beijing was still high. The prevalence rate in rural area had exceeded the level in urban area. Adjustment and attention should be made according to the prevalence features and weakness existed in present chronic disease control strategy.

Objective To investigate the mental health status of female workers. Methods The mental health status of 815 female workers from Hangzhou was investigated with symptom check list-90 (SCL-90).Results Only 5％ of factor scores were abnormal in female workers. In addition to the physical symptom factor scores, other 8 factor scores in female workers were lower than the national normal based on SCL-90 investigation (P＜0.01). All factor scores of female workers in electronic industry were higher than those in other industries (P＜0.01). Conclusion The mental health status of female workers is well except for female workers in electronic industry. It is suggested that effects of factors affecting psychological health on female workers are different in the various types of industry.

According to the result, 24.25% of these genes belonged to the unknown functional class, which was the largest classification unit according to the classification analysis of genes by eggNOG. The rest were classified as energy conversion, amino acid transport and metabolism, nucleotide transport and metabolism, carbohydrate transport and metabolism, coenzyme transport and metabolism, and lipid transport and metabolism, etc.Huangqi Liuyi decoction may play a therapeutic role in the treatment of type 2 diabetes mellitus through four metabolic pathways, namely environmental information processing, cellular process, organismal system and human diseases according to KEGG enrichment analysis. This study shows that, Huangqi Liuyi decoction can significantly improve the fasting blood glucose and glycosylated hemoglobin in type 2 diabetic rats.

Objective: To develop a predictive model for pathologic complete response (pCR) of ipsilateral supraclavicular lymph nodes (ISLN) after neoadjuvant chemotherapy for breast cancer and guide the local treatment. Methods: Two hundred and eleven consecutive breast cancer patients with first diagnosis of ipsilateral supraclavicular lymph node metastasis who underwent ipsilateral supraclavicular lymph node dissection and treated in the Breast Department of Henan Cancer Hospital from September 2012 to May 2019 were included. One hundred and forty two cases were divided into the training set while other 69 cases into the validation set. The factors affecting ipsilateral supraclavicular lymph node pCR (ispCR)of breast cancer after neoadjuvant chemotherapy were analyzed by univariate and multivariate logistic regression analyses, and a nomogram prediction model of ispCR was established. Internal and external validation evaluation of the nomogram prediction model were conducted by receiver operating characteristic (ROC) curve analysis and plotting calibration curves. Results: Univariate logistic regression analysis showed that Ki-67 index, number of axillary lymph node metastases, breast pCR, axillary pCR, and ISLN size after neoadjuvant chemotherapy were associated with ispCR of breast cancerafter neoadjuvant chemotherapy (P<0.05). Multivariate logistic regression analysis showed that the number of axillary lymph node metastases (OR=5.035, 95%CI: 1.722-14.721, P=0.003), breast pCR (OR=4.662, 95%CI: 1.456-14.922, P=0.010) and ISLN size after neoadjuvant chemotherapy (OR=4.231, 95%CI: 1.194-14.985, P=0.025) were independent predictors of ispCR of breast cancer after neoadjuvant chemotherapy. A nomogram prediction model of ispCR of breast cancer after neoadjuvant chemotherapy was constructed using five factors: number of axillary lymph node metastases, Ki-67 index, breast pCR, axillary pCR and size of ISLN after neoadjuvant chemotherapy. The areas under the ROC curve for the nomogram prediction model in the training and validation sets were 0.855 and 0.838, respectively, and the difference was not statistically significant (P=0.755). The 3-year disease-free survival rates of patients in the ispCR and non-ispCR groups after neoadjuvant chemotherapy were 64.3% and 54.8%, respectively, with statistically significant differences (P=0.024), the 3-year overall survival rates were 83.8% and 70.2%, respectively, without statistically significant difference (P=0.087). Conclusions: Disease free survival is significantly improved in breast cancer patients with ispCR after neoadjuvant chemotherapy. The constructed nomogram prediction model of ispCR of breast cancer patients after neoadjuvant chemotherapy is well fitted. Application of this prediction model can assist the development of local management strategies for the ipsilateral supraclavicular region after neoadjuvant chemotherapy and predict the long-term prognosis of breast cancer patients.
