Objective To assess the income status of primary care providers and to explore the determinants of income in a county of Dali. Methods In August 2016, the questionnaire was employed to collect the data of income status of 191 rural health workers and 217 village doctors in the county. Results Through the study, we found that the income of rural health workers in the county was 34, 000 (26, 000, 46,000) yuan with a satisfaction rate of 62.3% (95% CI 55.4%~69.2%) and no change (74.7%) was seen in the income among majorities after implementing the Zero Mark-up Policy for essential medicines. For the village doctors, the income was 20,000 (15,000, 24,000) yuan with a satisfaction rate of 40.6% (95% CI 34.0%~47.1%) and a fall of the income was found in more than half of the doctors after the implement of the policy. Conclusion Health care workers in towns are quite satisfied with their income whereas those in health stations of villages are not content, compared with the average income at the national level. We should increase government's investments on grass-root healthcare team, improve the incentive pay plans and promote the integrated management of health facilities in towns and villages.

OBJECTIVETo investigate the feasibility of reducing THM precursors and controlling bromate taste and odor in drinking water taken from the Yellow River by an ozonation combined system.
METHODSThe appropriate ozone dosage was determined, and then the changes of TOC, UV254 and THM formation potential (THMFP) in the combined system were evaluated.
RESULTSOne mg/L ozone could effectively remove taste and odor and meet the maximum allowable bromate level in drinking water. The pre-ozonation increased THMFP, but the conventional treatment system could effectively reduce the odor. The bio-ceramic filter could partly reduce CHCl3FP, but sometimes might increase CHCl2BrFP and CHClBr2FP. The biological activated carbon (BAC) filter could effectively reduce CHCl3FP and CHCl2BrFP, but increase CHClBr2FP. Compared with other filters, the fresh activated carbon (FAC) filter performed better in reducing THMFP and even reduced CHClBr2FP.
CONCLUSIONThe combined system can effectively reduce taste, odor, CHCl3FP, and CHCl2BrFP and also bring bromate under control.

OBJECTIVETo assess the condition of myocardial injury after cardiopulmonary bypass (CPB) and the effects of breviscapine (BVC) on cardiac function in children undergoing open heart surgery.
METHODSThirty-six children (ASA II or III, aged 2-65 months) scheduled to receive ventricular septal defect repairing were randomly assigned to three groups, the control group treated with saline, and the BVC treated groups treated respectively with low dose (0.5 mg/kg) and high dose (1.0 mg/kg) BVC, 12 patients in each group. Saline or BVC (in volume of 15 mL) was administered intravenously after induction of anesthesia with micro-pump within 30 min. Blood levels of troponin I (cTn-I ) and malondialdehyde (MDA) were measured at different time points: pre-operation (T0), during aortic unclamping (T1), and 30 min, 1 h, 6 h, 24 h after aortic unclamping (T2, T3, T4, T5). And the time of operation, CPB, aortic unclamping, and the condition of drainage in 24 h after operation as well as the dosages of narcotics (midazolam, propofol and fentanyl) used were recorded.
RESULTSNo significant difference among groups was found in terms of sex ratio, age, body weight, time of aortic unclamping, CPB and operation, as well as the dosages of narcotics used and the volume of post-operation drainage. Compared with baseline (T0), levels of cTn-I at T1, T4 and T5 increased significantly in all three groups (P<0.01), with the peak revealed at T4; cTn-I in the control group were higher than those in the low dose BVC treated group at T1 and T4 (P<0.01), and those in the high dose BVC group at T1, T4, and T5, while it was insignificantly different between the two BVC treated groups. Level of plasmal MDA began to rise in all groups at T1 with the peak revealed at T2, it lowered after then, and reached the baseline at T5; comparison between groups showed that it was lower in the BVC treated groups than in the control group at T1-T4.
CONCLUSIONSDifferent degree of cardiac injury always happens after open heart surgery and CPB, showing high level of cTn- I within 24 h with the peak revealed at 6 h after aortic unclamping. Intravenous perfusion BVC before CPB at the dose of 0.5 or 1 mg/kg could protect the cardiac function to some extent.

OBJECTIVETo study the factors affecting the management and treatment of immigrant workers with tuberculosis, to determine the most effective measures and to provide an academic basis for tuberculosis control and prevention strategies targeting the immigrant population.
METHODSA self-designed questionnaire was administered to 1364 immigrant workers with tuberculosis (study group) and 436 local residents (control group) with tuberculosis.
RESULTSWhether a patient's tuberculosis status was discovered or not was related to the medical facilities initially visited, job mobility, and the individual worker's economic condition. The percentage of cases discovered was relatively low among those who made their first visit to a private clinic (39.0%), and 58.4% (796) of immigrant workers delayed their first consultation mainly due to neglecting symptoms (55.9%, 445), subjective perception of symptoms being not severe enough (19.3%, 154) to visit a physician and the inconvenience of visiting a hospital because of its being far away from home (15.8%, 47). As comparing immigrant workers with local residents, the differences of the delay reason between the two groups were statistically significant (chi(2) = 21.49, P < 0.01). And 39.9% (544) of immigrant workers and 49.1% (214) of local residents had had late confirmation. The differences of the delay reasons between the two groups were insignificant (chi(2) = 7.31, P = 0.293). And 17.6% (240) patients of immigrant workers and 13.1% (57) patients of local residents did not keep to their drug regimens in a timely fashion. The differences of the reasons between the two groups were insignificant (chi(2) = 6.66, P > 0.05). And 77.5% (1057) of immigrant workers and 31.8% (138) of local residents were considered that taking medicine in supervision spot might have impact on their lives and work. The differences of the reasons between the two groups were significant (chi(2) = 9.71, P < 0.05). All 79.2% (1080) of immigrant workers and 63.3% (276) of local residents did not obtain medicine according to prescriptions. The differences of reasons between the two groups were statistically significant (chi(2) = 24.84, P < 0.01). And 51.2% (699) of immigrant workers and 46.1% (201) of the registered population did not follow up with doctors' directions for lab tests. The differences of the reasons between the two groups were insignificant (chi(2) = 3.26, P > 0.05).
CONCLUSIONThe influential factors in tuberculosis management and treatment were complex. Prevention strategies should focus on health education and promotion activities to improve awareness in seeking medical services. Also, developing and standardizing reference mechanisms for patients, and alleviating the economic burden of the workers will be critical to reduce the tuberculosis incidence.

OBJECTIVETo analyze the incidence and mortality of lung cancer patients among residents in Yangpu District of Shanghai from 2002 to 2010.
METHODSThe data of lung cancer cases in permanent residents of Yangpu district were collected from the database of the registration and management system in Shanghai city. Temporal trend in the incidence of lung cancer was analyzed by using annual percent change (APC) mode1. The survivals were calculated using SPSS 16.0 and Joinpoint Regression Program 3.5.1 software.
RESULTSA total of 5726 cases of lung cancer were diagnosed from January 2002 to December 2010. Of those, 3865 were males with an average age of onset 70.08 years, and 1861 were females with an average age of onset 70.88 years. The crude incidence rate was 77.36/10(5) in men, significantly higher than 39.31/10(5) in women (U = 24.84, P < 0.01). The standardized incidence rate was 25.23/10(5) in men, significantly higher than 13.47/10(5) in women (U = 13.24, P < 0.01). A total of 5248 cases died of the disease in this period. Of those, 3586 were men. The crude mortality was 71.77/10(5) in men, significantly higher than 35.11/10(5) in women (U = 24.67, P < 0.01). The standardized mortality was 21.72/10(5) in men, significantly higher than 11.08/10(5) in women (U = 13.01, P < 0.01). Both the incidence and mortality rates increased apparently in those older than 45 years. The 1- to 5-year survival rates in all cases were 37.42%, 22.71%, 15.73%, 12.32%, and 10.53%, respectively. The 1- to 5-year survival rates in male cases were significantly lower than those in female cases (P < 0.05 for each comparison). The 1- to 5-year survival rates of the patients whose tumor had been surgically removed were significantly higher than those in the patients without surgery (P < 0.05 for each comparison).
CONCLUSIONSThe incidence of lung cancer is close to the mortality in the residents of Yangpu District of Shanghai city. Surgical resection treatment improves the prognosis of lung cancer.

OBJECTIVETo analyze the incidence and survival rates of primary liver cancer (PLC) among residents in Yangpu district of Shanghai.
METHODSA total of 9 730 736 permanent residents (male 4 996 390 and female 4 734 346) of Yangpu district in Shanghai were recruited in the study between year 2002 and 2010; among whom 2726 PLC cases were diagnosed and 2427 death cases were certified. The incidence and mortality of PLC were calculated under the analysis of the new PLC cases and death cases between year 2002 and 2010. The rates were standardized by the demographic composition developed in the Fifth Nationwide Census in year 2000, in order to analyze the survival condition of PLC patients and explore the prognosis of surgical excision treatment.
RESULTSAmong the new PLC cases between year 2002 and 2010, 1966 cases were male, whose average age of onset was 59.81; while 760 cases were female, whose average age of onset was 68.93. The crude incidence rate was 39.35/100 000 in male, which was higher than it in female, as 16.05/100 000. The difference showed statistical significance (U = 7.32, P < 0.01). The standardized incidence rates were 21.98/100 000 and 6.96/100 000 in male and female, respectively. The difference showed statistical significance (U = 221.76, P < 0.01). There were 2427 PLC death cases in total, including 1734 male death cases and 693 female death cases. The crude mortality rate was 34.71/100 000 in male and 14.64/100 000 in female, whose difference were statistically significant (U = 6.68, P < 0.01). The standardized mortality rate was 19.16/100 000 in male and 6.06/100 000 in female, whose difference were statistically significant (U = 207.18, P < 0.01). The incidence and mortality rates both increased apparently since males aging over 35 and females over 45. The 1 - 5 year survival rates of PLC patients were 33.95%, 23.11%, 17.04%, 14.42% and 12.29%, respectively. In the surgical excision treatment group (321 cases), the 1 - 5 year survival rates were separately 66.78%, 52.87%, 41.88%, 33.57% and 32.64%; while in the non-surgical treatment group (2405 cases), the 1 - 5 year survival rates were separately 29.04%, 18.58%, 13.30%, 11.16% and 9.01%. The differences in 1 - 5 year survival rates between surgical and non-surgical groups all showed statistical significance (U = 12.78, 10.52, 8.28, 5.56 and 5.12, respectively, P < 0.01).
CONCLUSIONThe incidence of PLC was close to its mortality in Yangpu district of Shanghai. The male incidence and mortality rates were significantly higher than female corresponding rates. The surgical excision treatment could improve the prognosis of PLC.
