BACKGROUND: Lipid abnormalities are prevalent among people living with human immunodeficiency virus (HIV) (PLWH) and contribute to increasing risk of cardiovascular events. This study aims to investigate the incidence of dyslipidemia and its risk factors in PLWH after receiving different first-line free antiretroviral regimens. METHODS: PLWH who sought care at the Third People's Hospital of Shenzhen from January 2014 to December 2018 were included, and the baseline characteristics and clinical data during the follow-up were collected, including total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C). The risk factors of dyslipidemia after antiretroviral therapy were analyzed with the generalized estimating equation model. RESULTS: Among the 7623 PLWH included, the mean levels of TC, HDL-C and LDL-C were 4.23 ± 0.85 mmol/L, 1.27 ± 0.29 mmol/L and 2.54 ± 0.65 mmol/L, respectively, and the median TG was 1.17 (IQR: 0.85-1.68) mmol/L. Compared with that in PLWH receiving tenofovir disoproxil fumarate (TDF) + lamivudine (3TC) + ritonavir-boosted lopinavir (LPV/r), zidovudine (AZT) + 3TC + efavirenz (EFV), and AZT + 3TC + LPV/r, the incidence of dyslipidemia was lower in PLWH receiving TDF + 3TC + EFV. In multivariate analysis, we found that the risks of elevations of TG, TC, and LDL-C were higher with TDF + 3TC + LPV/r (TG: odds ratio [OR] = 2.82, 95% confidence interval [CI]: 2.55-3.11, P < 0.001; TC: OR = 1.24, 95% CI: 1.14-1.35, P < 0.001; LDL: OR = 1.06, 95% CI: 1.00-1.12, P = 0.041), AZT + 3TC + EFV (TG: OR = 1.41, 95% CI: 1.28-1.55, P < 0.001; TC: OR = 1.43, 95% CI: 1.31-1.56, P < 0.001; LDL: OR = 1.18, 95% CI: 1.12-1.25, P < 0.001), and AZT + 3TC + LPV/r (TG: OR = 3.08, 95% CI: 2.65-3.59, P < 0.001; TC: OR = 2.40, 95% CI: 1.96-2.94, P < 0.001; LDL: OR = 1.52, 95% CI: 1.37-1.69, P < 0.001) than with TDF + 3TC + EFV, while treatment with TDF + 3TC + LPV/r was less likely to restore HDL-C levels compared with TDF + 3TC + EFV (OR = 0.95, 95% CI: 0.92-0.97, P < 0.001). In addition to antiretroviral regimens, antiretroviral therapy duration, older age, overweight, obesity and other traditional factors were also important risk factors for dyslipidemia. CONCLUSION The incidence of dyslipidemia varies with different antiretroviral regimens, with TDF + 3TC + EFV having lower risk for dyslipidemia than the other first-line free antiretroviral regimens in China.

Objective To explore the risk factors of nosocomial infections to provide a reference for prevention and control of nosocomial infection.Methods The data of 680 patients with nosocomial infection in this hospital from January 2015 to December 2016 were retrospectively collected.The characteristics of nosocomial infection were analyzed from the aspects of age,hospitalization department,infection site,etc.Results A total of 680 cases of nosocomial infection accounted for 1.67％(680/40 657) of all hospitalization patients,including 316 cases(nosocomial infection rate was 2.47％) of 61-80 years old.The infection rate was the highest in ICU(24.90％),followed by the nephrology department(4.99％).For infection sites,the maximal cases-times in infection site was lower respiratory tract(413 case-times),followed by urinary tract and superficial incision(each 68 case-times).The pathogenic detection rate was 45.03％,and 190 strains of pathogens were detected.The top five places were Escherichia coli(47 strains),Klebsiella pneumoniae(28 strains),Pseudomonas aeruginosa (23 strains),Staphylococcus aureus (22 strains) and Bauman Acinetobacter (16 strains).Logistic regression analysis showed that age larger than 60 years old,hospitalization time longer than 60 d,indwelling urinary catheter,peripherally inserted central catheter(PICC),tracheotomy and enteral nutrition were the risk factors for nosocomial infection occurrence.Conclusion Hospital should put the emphasis on preventing nosocomial infection of lower respiratory tract and strengthen the nosocomial infection management of key departments like ICU.

Aim To prepare evodiamine butyryl deriva-tive (EBD) and evodiamine butyryl derivative-loaded solid lipid nanoparticles (EBDLN), and study its re-lease in vitro,and to investigate its in situ gastrointesti-nal absorption. Methods EBD was prepared by a one-step synthetized method, and then EBDLN was prepared by a film dispersion method. Dynamic dialy-sis was used to evaluate drug release in vitro,and sin-gle-pass gastrointestinal perfusion was employed to study the gastrointestinal absorption of EDM,EBD and EBDLN. Results In identical release media, there were identical drug release tendencies of EBD and EB-DLN, but the release rate of EBDLN was faster than EBD. Compared with EDM and EBD, the Kavalues and Pappvalues of EBDLN in every perfusion segment increased significantly. The Kaof EBDLN in stomach, duodenum, jejunum, ileum and colon was 110.14-fold,56.70-fold,51.23-fold,45.70-fold and 127.23-fold of free EDM respectively. The Pappvalue of EB-DLN was 9.74-fold, 4.48-fold, 3.82-fold and 11.3-fold of that of free EDM. Conclusion EBDLN has sustained effect and can enhance the gastrointestinal absorption of EDM and EBD.

Objective To determine the values and variation tendency of a disintegrin and metalloprotease 12-S(ADAM12-S)of early pregnancy, and discuss the value of ADAM12-S to the ectopic pregnancy in the first trimester.Methods 150 early pregnancy cases (from the 5th to 10th week of pregnancy)were selected in Huanggang Women &Children's Healthcare Hospital.There were 102 cases of normal pregnancy,48 cases of ectopic pregnancy.The AutoDELFIA immunoassay platform was used to measure the value of ADAM12-S in the serum.Results Of the 102 normal pregnancies, the values of ADAM12-S in 5th-10th week of pregnancy linearly increase with gestationalage.The correlation coefficient was 0.9217 (P<0.05).While the values of ADAM12-S in the ectopic pregnancy group were significantly lower than the normal pregnancy group and not linearly increased with gestationalage.The correlation coefficient was 0.2817.There was statistically significant difference between the two groups (P<0.05).Conclusion The values of ADAM12-S is stable in the first trimester of normal pregnancy,while it is much more lower in abnormal pregnancy.ADAM12-S has great significance in the diagnosis of ectopic pregnancy of the first trimester.

The related substances in docetaxel injection were identified by LC-MS/MS. Ethyl acetate was used to extract the injection to remove the pharmaceutical excipients. HPLC separation was carried out on a Hedera ODS-2 column (150 mm x 2.1 mm, 5 microm) with a mobile phase consisting of acetonitrile - 0.1% acetate acid aqueous solution (40: 60). Electrospray ionization source was set in the positive mode for the LC-ESI-MS/MS, and the ion monitoring modes were full scan and product ion scan. According to the mass spectra of the related substances, the fragment profiles were explained, and the chemical structures were elucidated. Docetaxel and its main related substances were well separated. Nine related substances in docetaxel injection were detected by LC-MS/MS. Their chemical structures were proposed, and four of them were identified in the docetaxel injection for the first time. The established LC-MS/MS method is effective in the separation and identification of the related substances in docetaxel injection. The test results are useful for its quality control.

Objective To analyze the effects of health risk factors on presenteeism in enterprise employees.Methods A hospital in Jinan of Shandong province and a publishing enterprise in Beijing were selected as target settings of this cross-sectional study. Questionnaire survey was carried out to collect information on demographic data,health condition and presenteeism,and multiple logistic regression was used to analyze the influence of health risk factors on labor-related presenteeism.Results Insufficient physical activity was found in 42％ percent of the participants,and those with heavy-loaded pressure,overweight or obesity,high blood pressure and unhealthy diet habit accounted for 46％,41％,40％ and 34％,respectively. Proportions of employees with presenteeism varied with age ( x2 =10.1665,P =0.0377),occupation ( x2 =35.3579,P ＜ 0.05 ) and education level ( x2 =50.5377,P ＜ 0.05 ).Female employees ( P =0.0323,OR =1.728,95％ CI 1.047 to 2.850),graduates ( P ＜ 0.05,OR =6.159,95％ CI 2.510 to 15.109),overweight or obesity individuals ( P =0.0076,OR =1.673,95％ CI 1.147 to 2.44) and adults with poor self-perception of health ( P =0.0049,OR =2.284,95％ CI 1.285 to 4.060)seemed to be more likely to be presenteeism.Conclusions Overweight or obesity and poor self-perception of health may be associated with labor-related presenteeism.
