Objective To observe the dynamic level of platelet activation and to analyze the correlation between platelet activation and systemic inflammatory response syndrome(SIRS)in patients with acute ischemie stroke. Methods Mean platelet component concentration(MPC)and white blood count(WBC)were serially determined in patients with acute isehemic stroke,and other parameters including initial plasma fibrinogen(FIB)and adenosine diphosphate(ADP)aggregative rate were also determined.All parameters were compared between the SIRS group and the non-SIRS group.Correlation was analyzed between initial MPC and SIRS score,WBC,FIB and ADP aggregative rate. Results MPC level was declined slightly on the first day,and was followed by a relatively low MPC level from the second day to the forty-fifth day.The average level was fluctuated between 229 g/L and 242 g/L.There was no significant difference in initial FIB(t=1.835,P=0.07)between the SIRS group and the non-SIRS group,but the differences of other parameters had statistical significance(all P<0.01).In the first three days,MPC level was negatively correlated with SIRS score(r=-0.392,-0.376,-0.341,t=3.484,3.405,3.125 respectively,all P<0.01),but not correlated with WBC,FIB and ADP aggregative rate(P>0.05). Conclusions Platelets maintain an activated state during the entire course of ischemic stroke.The initial level of platelet activation.WBC count and ADP aggregative rate are higher in SIRS patients than in non-SIRS patients.The initial level of platelet activation suggests the severity of SIRS,and may be one of the independent risk factors for SIRS.

To observe the clinical efficacy of combined acupuncture and Tuina in the treatment of enuresis following occult cleft spine and seek quantified indexes for result assessment, 40 subjects were treated by above methods and B-ultrasonically examined before and after treatment to determine the capacity of bladder and the residual urine inside it. The total effective rate was 90%; there was a difference of the capacity of bladder between before and after treatment (P<0.05); 11 cases suffered from residual urine, and there was also significant difference of residual urine between before and after treatment (P<0.01). It is revealed that this method can increase the capacity of bladder and diminish residual urine.

Objective:
To analyze the epidemiological characteristics of occupational diseases in Gansu Province, China in 2010-2017, and to provide a scientific basis for the prevention and control of occupational diseases.
Methods:
The cluster sampling method was adopted to make statistical analysis of 1339 cases of occupational disease reported by "occupational disease and occupational health information monitoring system" in Gansu province from 2010 to 2017, to investigate the diseases, regions and industries of occupational diseases in June 2018.
Results:
A total of 1339 cases of occupational diseases (39 types, 8 classes) were diagnosed and reposed in 2010-2017. The three most frequent diseases were pneumoconiosis (87.53%, 1172/1339), occupational poisonings (5.83%, 78/1339), and occupational ear, nose, and throat (ENT) diseases (3.14%, 42/1339). The cases of silicosis accounted for 54.61% (640/1172) of all cases of pneumoconiosis, the second was coalworker pneumoconiosis, which accounted for 38.57% (452/1172). In the cases of occupational poisonings, 32.05% (25/78) suffered from carbon monoxide poisoning. Patients with occupational diseases were reported in 14 districts of Gansu, mostly in Lanzhou (27.52%, 347/1261), Jinchang (16.57%, 209/1261), and Baiyin (14.20%, 179/1261). The reported cases are mainly concentrated in mining (71.56%, 468/654) and manufacturing (21.87%, 143/654), the types of state-owned economy (55.63%, 692/1244) and private economy (33.68%, 419/1244), large (43.41%, 540/1244) and small enterprises (35.21%, 438/1244) in 2010-2017 in Gansu.
Conclusion
The pneumoconiosis caused by silicious and coal dust and the occupational poisonings caused by carbon monoxide seem to be the main occupational hazards in Gansu province. Occupational diseases occur in all districts of Guangzhou and in various industries. The state-owned economy and private sector, large and small enterprises should be the focuses of occupational health supervision.

Objective To analyze the influencing factors on condom use among 35-yearsor-older female sex workers (OFSWs) in Qingdao by using the three-level logistic model.Methods From March to June 2014,OFSWs were recruited in Qingdao,using respondent-driven sampling.Related information on OFSWs and their recent five sexual partners (not including husband) were obtained by conducting a questionnaire survey on OFSWs.A Three-level logistic regression model was conducted to analyze the influencing factors of condom use between OFSWs and their sexual partners.Results A total of 420 OFSWs participated the survey as well as information on 2 100 sexual partners.Results from the empty model showed that the use of condoms among OFSWs having an aggregation that related to the levels of working sites and their own behaviors.Results from the three-levels of logistic model analysis showed that,OFSWs that having had junior middle school education (OR=1.450,95%CI:1.054-1.994)/high school education or above (OR=2.264,95% CI:1.215-4.222),knowing the function of condom use (OR=2.004,95% CI:1.273-3.154) would have higher rates of condom use.OFSWs with higher score of attitude on condom use (OR=0.796,95%CI:0.745-0.849),having had syphilis infections in the past (OR=0.657,95% CI:0.478-0.902) would have lower rate of condom use.For the sexual partners,the rate of condom use among OFSWs' regular partners were higher than that of OFSWs' boyfriends (OR=15.291,95%CI:8.441-27.700;OR=29.032,95% CI:15.413-54.682).Conclusion Condom use of OFSWs was affected by behaviors of both OFSWs themselves and their sexual partners.Prevention and control programs should focus on OFSWs and their sexual partners at the same time.The key intervention contents should include target populations as:OFSWs with low level of education,having had infections of syphilis,those who do not use condoms with their trusted partners.

Background As the population ages, there has been a growing focus on the decline in fertility. Research has identified age and fertility history as the primary influencing factors. Nevertheless, there is a deficiency in fundamental data regarding the fertility status among different industries. Objective To investigate the fertility status and influencing factors among female workers aged 22-35 years in different industries. Methods From July 2020 to February 2021, a cross-sectional survey was conducted using a staged sampling approach. This survey specifically targeted 22-35-year-old married female workers with a history of pregnancy in industries such as education, healthcare, finance, and telecommunications, totaling 22903 participants. The survey encompassed industry, demographic characteristics, pregnancy history, time to pregnancy (TTP), and other influencing factors. The influencing factors of decline in fertility were identified by chi-square test and Cox proportional hazards regression. Subsequent industry-specific Cox proportional hazards regression models were used to compared fertility decline patterns across a spectrum of industries after selected influencing factors were adjusted. Results Among the 22903 respondents, 19194 valid questionnaires were collected, with a valid recovery rate of 83.8%. The cumulative pregnancy rates (CRP) of 1-6 months and 1-12 months for the 22-35-year-old female workers were 67.23% and 91.33% respectively. The multivariate analysis showed that region, age, education level, personal annual income, housework time, coping style, gravidity, parity, and spontaneous abortion were influencing factors of fertility decline (P<0.05). Female workers with ≥3 gravidities and ≥2 spontaneous abortions had a higher risk of fertility decline, with hazard ratios (HR) and associated 95% confidence interval (95%CI) of 0.633 (0.582, 0.688) and 0.785 (0.670, 0.921) respectively (P<0.01). Compared to the education industry, the healthcare and finance industries showed a higher risk of fertility decline, with HR (95%CI) values of 0.876 (0.834, 0.920) and 0.909 (0.866, 0.954), respectively (P<0.05). These two HR (95%CI) values remained statistically significant [0.899 (0.852, 0.948) and 0.882 (0.833, 0.934) respectively, P<0.05)] after further adjustment with nine influencing factors such as region and age. Conclusion Regions, age, education level, personal annual income, housework time, coping style, pregnancy and childbirth times, and natural abortion times are influencing factors of fertility decline in female workers. Compared to the education industry, the healthcare and finance industries have a higher risk of declining fertility.
