Objective To understand the status of pregnant women body maternal body mass management knowledge and analyze its influencing factors.Methods In 28 specialist maternity hospital,the production inspection of 631 pregnant women were investigated with self-designed maternal body mass management knowledge questionnaire.Results At present, the knowledge of the maternal body mass management of pregnant women mainly came from the network (32.3%),the lecture (26.5%)of the hospital organization,the access to the knowledge manual (26%),and other ways (19.2%);multiple stepwise regression analysis showed that pregnant women marriageable age,educational level,production time were the influential factors of body mass management (P <0.05).Conclusions The body mass management knowledge of pregnant women is poor.It is relevant with that pregnant women do not pay attention to the body mass management and they are lack of approaches to master the knowledge.So the maternity hospital at all levels should emphasis on body mass management knowledge education,establish body mass management clinics and hospital network platform for the pregnant women,in order to promote the level of body mass management knowledge of pregnant woman on the basis of assessment.

OBJECTIVE:To provide reference for rational drug use in clinic and nosocomial infection control. METHODS:Acinetobacter baumannii(AB)were collected from our hospital during Jan. 2014-Jun. 2017. Drug sensitivity tests were conducted by using K-B method and MIC method. Drug-resistance genes of multidrug-resistant Acinetobacter baumannii(MDR-AB)were amplified by PCR,and compared with GenBank database by using Blast comparison. RESULTS:A total of 1 758 strains of AB were detected,and mainly came from sputum and throat swab(65.24%),followed by urine(18.49%). These infected patients were mainly distributed in the departments of ICU(38.51%)and respiratory medicine(24.00%),respectively. Drug resistance of clinical isolated AB to most commonly used antibiotics were more than 40%,such as compound sulfamethoxazole,piperacillin sodium and tazobactam sodium,gentamicin,cefepime,levofloxacin,minocycline,imipenem,etc.;it had increased year after year. Drug resistance to colistin was lower than 5% and decreased year by year.A total of 673 strains of MDR-AB were detected, and detection rates were 22.77%,29.82%,52.09%,54.33%,respectively.Among 110 strains of MDR-AB,detection rates of TEM, AmpC,IMP,VIM,OXA-23,OXA-24,OXA-51,aac(6′)-Ⅰ,aac(3)-Ⅰ,ant(3″)-Ⅰ,anmA,gyrA,parC gene were 97.27%, 91.82%,49.09%,12.73%、90.91%,12.73%,98.18%,34.55%,60.91%,89.09%,87.27%,77.27%,82.73%,respectively. Results of Blast comparison showed that point mutation occurred in 83rd and 121st base of gyrA gene,144th base of parC gene. CONCLUSIONS:AB mainly come from sputum and throat swab specimens in our hospital,and infected patients are mainly distributed in the departments of ICU and respiratory medicine. Drug resistance is serious,and the detection rate of MDR-AB is increased year by year. Main genes of multidrug-resistant strains mainly include TEM,AmpC,OXA-23,OXA-51,ant(3″)-Ⅰ, anmA,etc.,and mutation of gyrA and parC gene are found. It is necessary to strengthen the management of classification use of antibiotics and strengthen the monitoring of AB drug resistance. According to the results of drug sensitivity test,antibiotics are selected rationally to prevent or delay planting and cross transmission of AB-resistant strain.

Objective: To understand the mortality and influencing factors on injecting drug users (IDUs) with HIV/AIDS, in Guizhou province, 1996-2015. Methods: A retrospective cohort study was conducted on IDUs with HIV/AIDS that were reported through national comprehensive HIV/AIDS information system, in Guizhou province during 1996-2015. Cox proportional hazard regression model was used to analyze the influencing factors on the mortality of HIV/AIDS. Results: A total of 3 958 cases of IDUs with HIV/AIDS were recruited in this study, with all-cause mortality rate of 44.01% (1 742/3 958) and total mortality rate of 7.80/100 person-years, respectively. The median survival time between diagnosis and death was 8.08 years. Mortality rate was 3.57/100 person-years in the group receiving antiretroviral therapy (ART). The mortality appeared to be 4.08/100 person-years in the group who were on methadone maintenance treatment (MMT). Data from the multiple regression analysis indicated that factors of gender, ethnicity, age when HIV/AIDS diagnosis was made, CD₄⁺T lymphocyte (CD₄) count at the first testing, ART and MMT were significantly associated with deaths among these people. The risk of death in females was 0.82 times (95%CI: 0.69-0.98) higher than that in males. The risk of deaths among the ethnic minority subjects was 1.39 times (95%CI: 1.21-1.60) higher than that of the Hans. The risk of death appeared to be 2.44 times higher (95%CI: 1.07-5.56) in the over-50-year of age group than in the <20 year-old group, when HIV/AIDS was diagnosed for the first time. The risk of death in CD₄ ≥500/μl group in the first time was 0.27 times (95%CI: 0.22-0.32) more than CD₄ <200/μl group in the firs time. The risk of death in cases who were treated with ART or MMT was 2.83 times (95%CI: 2.45-3.26) and 1.35 times (95%CI: 1.15-1.59) higher than those who did not receive any treatment, respectively. Conclusion Higher risks on death seemed to be related to the following factors: being male, older age at the time of diagnosis, lower CD₄ at diagnosis, not on ART or MMT among the IDUs with HIV/AIDS in Guizhou province, between 1996-2015.

RESULTSThere was no significant difference in the sensitivity of 12 anticancer drugs between PBL and tumor cells of patients with lung cancer (P > 0.05).

CONCLUSIONSThe chemosensitive test of the peripheral blood lymphocytes is valuable for reference of selecting anti-cancer drugs in clinic for lung cancer.

Objective:To evaluate the prediction power of HIV infection risk assessment tool and the applicability in MSM in Guizhou province.Methods:MSM were recruited through snowball sampling method. Questionnaire surveys were conducted among the MSM using HIV infection risk assessment tool, and combined with HIV serologic test results, the risk prediction power of HIV infection risk assessment tool was evaluated.Results:A total of 3 379 MSM were recruited from January 2018 to December 2019 in Guizhou. The HIV infection rate was 3.3%(111/3 379). The mean risk scores of HIV positive and HIV negative MSM were (12.15±3.08) and (12.07±3.07), respectively. The difference in risk score was significant between MSM with different HIV status ( t=8.69, P<0.001). According to the principle of decision tree, individual risk scores were divided into following three categories: ≤11.96, 11.97-14.80 and >14.80, the HIV infection rate was 0.8%, 4.3% and 8.6% respectively, suggesting that the higher the individual risk score was, the higher the HIV infection rate was (trend χ 2=88.18, P<0.001). Multivariate logistic regression analysis showed that the higher the individual risk score was, the higher the risk of HIV infection was. Compared to the total score ≤11.96, the a OR values at total scores of 11.97-14.80 and >14.80 were 6.34 (95% CI: 3.38-11.88) and 14.07(95% CI: 7.44-26.61), respectively. The risk of HIV infection in Miao ethnic group was higher than that in Han ethnic group (a OR=1.83, 95% CI:1.04-3.21), and the risk of HIV infection in those with education level of primary school and below was higher than that in undergraduates or those with education level of junior college and above (a OR=2.50, 95% CI:1.06-5.88), and the risk of HIV infection was higher in those who had bisexual behaviors than in those who had homosexual behaviors (a OR=1.95, 95% CI:1.19-3.19). The risk of HIV infection was higher in those who had never received HIV testing (a OR=1.53, 95% CI:1.01-2.33). The area under the receiver operating characteristic (ROC) curve and area under ROC (AUC) for HIV infection prediction was 0.751 (95% CI:0.710-0.792, P<0.001). The maximum Youden's index was individual risk score of 12.56, and the sensitivity of the risk assessment tool was 0.838, and its specificity was 0.412. Conclusions:The results of HIV infection risk assessment tool in Guizhou indicated that in MSM the higher the individual risk score, the higher the risk of HIV infection is. The tool can be used to evaluate the risk of HIV infection in MSM, but the specificity should be improved.

It is believed that all kinds of gynaecological diseases are mostly related to deficiency and stagnation of qi and blood. Medicinal insects are good at running and scurrying， with the effectiveness of activating blood circulation and dispelling blood stasis， moving qi and relieving pain， searching and dredging collaterals， attacking hardness and dissipating mass， and purging foetus and resolving mass， etc. Appropriate prescriptions can enhance the effectiveness of the formula in eliminating blood stasis and eliminating stagnation. In the treatment of menstrual disorders， chronic pelvic inflammatory disease， uterine cavity disease， incomplete miscarriage， ectopic pregnancy， and other gynaecological diseases， medicinal insects including Quanxie （Scorpio）， Wugong （Scolopendra）， Tubiechong （Eupolyphaga/Steleophaga）， Jiuxiangchong （Coridius chinenses）， Shuizhi （Hirudo）， Mangchong （Tabanus）， Dilong （Pheretima） and other insects for medicinal purposes could be used， and the self-prescribed empirical formulas such as Sanhuang Decoction （三黄汤）， Hongteng Decoction （红藤汤）， Penning Decoction （盆宁方）， Shapei Decoction （杀胚方）， and Gongwaiyun Decoction （宫外孕方） and so on， were all applied medicinal insects and showed effective in clinic.
