ObjectiveTo explore the role of tumor necrosis factor related apoptosis inducing ligand (TRAIL) and it's combination with chemotherapeutic agents in treatment of cervical cancer.Methods 100μl of cervical cancer cells suspension were added to each well of 96 well plates. Cells were incubated for 24 hours with TRAIL, Adriamycin (ADM), Mitomycin C (MMC) and TRAIL combined with chemotherapeutic agents at different concentration. Rates of apoptosis and death of cells were detected by flow cytometry.ResultsRates of apoptosis of cells were 20.1% by treated with 100 μg/L TRAIL singly, which was significantly different compared with groups without agents (P<0.01). Inhibitory rates were 36.0% by treated with 10.0mg/L MMC, 44.1% by ADM. However inhibitory rates reached 58.4% or 73.7% by 100.0 μg/L TRAIL +10.0 mg/L MMC or ADM. Combined of TRAIL and MMC, TRAIL and ADM resulted in a synergistic cytotoxic effect (P<0.05).ConclusionIn vitro, TRAIL is an agent for anti cervical cancer by inducing the apoptosis of tumor cell; TRAIL can enhance the effect of ADM and MMC.

Objective To explore the influence of up-regulated Foxp3 on Treg function and kidney transplantation chronic rejection reaction in rat model.Method The kidney transplantation chronic rejection reaction rat model was established.The F344 kidney was transplanted to Lewis rats,and retroviruses highly expressing Foxp3 were constructed.The Banff 97 hierarchical diagnostic criteria were used to diagnose chronic renal allograft nephropathy (CAN).The rat models were divided into three groups by random number table.In experimental group,the pSCV-BsdRFP-FoxP3 retroviruses were injected into the rats via the tail vein after operation.In negative control group,the pSCV-BsdRFP retroviruses were injected into the rats via the tail vein after operation.In blank group,the normal saline was injected into the rats via the tail vein after operation.Enzyme-linked immunosorbent assay (ELISA) was used to detect the changes of interleukin-10 (IL-10) and tumor necrosis factor-β (TGF-β) immediate,1,2,3,and 4 weeks after operation.The rats were killed at 4th week after operation,and kidney tissues were taken out for pathological examination.Result The pathological changes of CAN were observed at 4th week.The typical chronic rejection change was seen at 12th week.The levels of IL-10 and TGF-β were increased,and reached the peak at 3rd week.The levels of IL-10 and TGF-β in experimental group were higher than in negative control group and blank group at 1st,2nd,3rd,and 4th week.At 4th week,obviously different degrees of intimal thickening,and mild hyperplasia of interstitial fibers,glomerular sclerosis and infiltration with lymphocytes and plasma cells were observed in the three groups.In the experimental group,the lesions were mildest,and apparent neointimal hyperplasia was found.Conclusion pSCV-BsdRFP FoxP3 retroviruses can reduce the kidney transplantation chronic rejection reaction in rat model,and have the potential treatment effect.

Objective: To investigate the awareness, sexual behavior characteristics and infection status of AIDS among male floating population in Anhui Province, so as to provide insights into formulating prevention and control measures for male floating population. Methods: Male floating population of three occupations including construction workers, enterprise workers, and business operators in Wuhu, Tongling, Hefei, and Fuyang cities were selected using stratified cluster random method from April to August 2021. Demographic information, knowledge of AIDS and high-risk behaviors were collected through questionnaires surveys. The results of HIV, syphilis and hepatitis C virus (HCV) antibody testing were collected through laboratory tests. Awareness rate of AIDS knowledge, sexual behavior characteristics, and positive rates of HIV, syphilis, and HCV among male floating population of different occupations were analyzed. Results: A total of 1 616 people were enrolled, including 1 016 construction workers (62.87%), 253 enterprise workers (15.66%) and 347 business operators (21.47%), and had a mean age of (40.63±12.32) years. The overall awareness rate of AIDS knowledge among male floating population was 89.54%, the awareness rates of business operators, construction workers, and enterprise workers were 98.33%, 88.29% and 82.61%, respectively, and the difference was statistically significant (P<0.05). The proportions of consistent condom use during sexual intercourse with a spouse or cohabitant, during commercial sexual encounters, and with casual partners in the past year were 7.15% (91/1 273), 64.00% (16/25) and 50.00% (8/16), respectively. The proportions of construction workers, enterprise workers, and business operators who used condoms every time they had sexual behavior with their spouses/cohabitants in the past year were 4.54%, 11.63%, and 15.60%, respectively, with statistically significant differences (P<0.05). One case of HIV, one case of syphilis, and three cases of HCV antibody were detected. Conclusion The overall awareness rate of AIDS knowledge among the male floating population in Anhui Province is relatively high, but unsafe sex behaviors exist, which may lead to the risk of HIV infection.

Objective: To understand the awareness and service utilization of HIV preexposure prophylaxis (PrEP) and postexposure prophylaxis (PEP) among the young students aged 15-24 in Hefei, so as to provide reference for the prevention and treatment of AIDS among young students in the future. Methods: From May to June 2022, a stratified random cluster sampling method was used to select two different types of universities(undergraduate and vocational colleges) in Hefei, and a crosssectional survey was conducted among the 916 young students at the selected schools. The Chisquare test was used for statistical analysis. Results: Among the surveyed young students, 88.4% had heterosexual orientation, and 12.4% had sexual behavior including 8.8% of homosexual sexual behavior and 91.2% of heterosexual sexual behavior. The rate of condom use was 70.0% in the last homosexual intercourse, and the rate of condom use was 83.7% in the last heterosexual intercourse. About 41.9% of young students heard of PrEP, and the proportions of young students who knew about PrEP, consulted PrEP and used PrEP were 43.0%, 15.9% and 9.4% respectively. About 38.3% of young students had heard of PEP, and the proportions of young students who knew about PEP, consulted PEP and used PEP were 18.2%, 15.4% and 6.0%. Conclusions The awareness rate and utilization rate of PrEP and PEP among young students in Hefei are relatively low. PrEP and PEP publicity should be combined with education of HIV knowledge, and enhance the awareness rate of the young students, in order to reduce the risk of AIDS infection among young students with highrisk behaviors.

Objective: To investigate the influencing factors and population attributable risk percent (PAR%) of low back pain in automobile assemblers. Methods: A total of 634 assemblers from 11 automobile manufacturers in Shiyan City, Hubei Province were chosen as research subjects using judgment sampling method. The prevalence of low back pain in the past one year was investigated using Musculoskeletal Disorders Questionnaire. PAR% was used to analyze the contribution of influencing factors to low back pain. Results: The annual prevalence of low back pain was 68.8%. The results of multivariate logistics regression showed that length of service>15 years, high school or secondary college education or above, standing most of the time, sitting most of the time, the proportion of cumulative time of poor posture in work shift time ≥1/8, and bending for insufficient height of working space were the risk factors for low back pain (all P<0.05). The PAR% of the proportion of cumulative time of poor posture in work shift time ≥1/8 was 43.0%, 37.8% for standing most of the time, and 12.8% for bending for insufficient height of working space. Conclusion: The annual prevalence of low back pain was higher in automobile assemblers. The influencing factors included individual factors and occupational factors. The proportion of cumulative time of poor posture in work shift time ≥1/8, standing most of the time and bending for insufficient height of working space should be taken as the priority intervention factors to reduce the prevalence of low back pain among assemblers in this enterprise.

Objective To observe the clinical effect of traditional Chinese medicine (TCM) characteristic lung rehabilitation in treatment of patients with chronic obstructive pulmonary disease (COPD) and TCM syndrome of lung and kidney qi deficiency at stable period. Methods Sixty patients with stable COPD and lung and kidney qi deficiency syndrome admitted to the First Affiliated Hospital of Anhui University of Chinese Medicine from June to August 2017 were enrolled, and they were divided into routine treatment group and lung rehabilitation treatment group according to the random number table method, each group 30 cases. The routine treatment group was given Seretide (serevent/futicasone) dry powderi nhalation therapy; on the basis of therapy in the routine treatment group, the lung rehabilitation treatment group was treated with TCM characteristic lung rehabilitation technology (acupoint application + Chinese medicine ionic induction + oral administration of Chinese medicine Liuweibuqi granules, delivery at appropriate intervals); both groups were treated for 2 months. The changes of TCM syndrome score, western medicine symptom score, the times of acute exacerbation of COPD, COPD assessment test (CAT) score, lung function indexes: forced expiratory volume in one second (FEV1), FEV1/forced vital capacity (FVC) were observed before and after treatment in two groups. Results After treatment, TCM syndrome score, western medicine symptom score, CAT score, and after treatment the times of acute exacerbation of COPD in both groups were significantly lower than those before treatment, and the above indexes in the lung rehabilitation treatment group were markedly lower than those in routine treatment group [TCM syndrome score:11.93±1.80 vs. 14.27±2.88, western medicine symptom score: 14.20±2.75 vs. 11.93±4.23, CAT score: 14.87±2.60 vs. 16.23±4.39, the times of acute exacerbation of COPD (times): 0.63±0.49 vs. 0.95±0.83, all P < 0.05]. The improvement of FEV1 in the two groups was not significant; but FEV1/FVC in lung rehabilitation treatment group was obviously higher than that before treatment, FEV1/FVC in lung rehabilitation treatment group was significantly higher than that in the routine treatment group [(57.93±7.27)% vs. (52.49±6.61)%, P < 0.05]. Conclusion The application of TCM characteristic lung rehabilitation in the treatment of COPD patients with stable lung and kidney qi deficiency syndrome based on bronchodilators and glucocorticoids can reduce the number of acute exacerbation, improve the patients' clinical symptoms and living quality, but the improvement of lung function is not significant.
