ABSTRACT
Objective:To screen the incidence of proteinuria in rural areas of Shanxi province and construct a risk prediction model of proteinuria based on machine learning algorithm.Methods:It was a cross-sectional investigation study. The residents ≥30 years old in rural areas of Shanxi province from April to November 2019 were screened by multi-stage stratified sampling method, and data from questionnaire surveys, physical examinations, and laboratory examinations were collected. Urine albumin/creatinine ratio ≥30 mg/g was defined as proteinuria, and the incidence of proteinuria was calculated. Subjects were divided into proteinuria group and non-proteinuria group. The machine learning binary classification model of proteinuria and non-proteinuria was constructed based on the stackable integrated logistic regression algorithm (SE-LR), logistic regression, support vector machine, decision tree, random forest and extreme gradient lift algorithms, respectively. The area under the receiver operating characteristic curve, accuracy, recall, and F1 weights were used to evaluate the predictive efficiency of the comparison models. Finally, the importance of the predictive features of the model with the best overall performance was ranked.Results:There were 8 869 rural residents included in the study, aged (58.59±9.49) years old, with 3 872 males (43.66%) and 4 997 females (56.34%). The prevalence of proteinuria in rural areas of Shanxi province was 13.49% (1 196/8 869). Blood pressure, pulse, body mass index, waist circumference, proportion of obesity or overweight, proportion of hypertension, proportion of moderate to severe salt intake, glycosylated hemoglobin, uric pH value, urinary specific gravity, proportion of positive urinary occult blood, proportion of positive urinary glucose, proportion of positive urinary ketone body, proportion of urinary red blood cell count ≥5/μl, proportion of urinary white blood cell count ≥10/μl and urinary α1 microglobulin in the proteinuria group were all higher than those in the non-proteinuria group (all P<0.05). The proportions of lack of exercise and drinking history in the proteinuria group were lower than those in non-proteinuria group (both P<0.05). The overall performance of SE-LR model was the best, with the area under the curve (0.736, 95% CI 0.719-0.746) slightly lower than that of the logistic regression model (0.745, 95% CI 0.680-0.762), and the highest accuracy (0.844), recall rate (0.621) and F1 weighting value (0.801). In the SE-LR model, the orders of importance of the top 10 features were urinary α1- microglobulin, urinary occult blood, urinary sugar, uric acid basicity, smoking history,overweight or obesity, body mass index, total cholesterol, glycosylated hemoglobin and hypertension. Conclusions:The prevalence of proteinuria is high in rural areas of Shanxi province. The risk prediction model of proteinuria established by machine learning algorithm can predict the risk of proteinuria and identify its risk factors, which can provide a scientific basis for disease prevention, intervention, and treatment in the community and clinic to a certain extent.
ABSTRACT
Objective:To investigate the incidence and mortality of lung cancer in the cancer registration areas of Shanxi Province in 2017.Methods:The cancer registration data reported by 12 tumor registration areas of Shanxi in 2017 were sorted out and stratified by urban and rural areas and gender. The number of incidence and death ,the crude incidence and mortality, the cumulative rate (0-74 years), age-specific incidence and mortality, Chinese population standardized rate and world population standardized rate were calculated. The incidence and mortality were standardized by the 2000 China census standard population composition and Segi's world standard population composition.Results:In 2017, there were 2 275 new cases and 1 736 deaths of lung cancer in the tumor registration area of Shanxi Province. The crude incidence rate of lung cancer was 46.72/100 000 (male 63.99/100 000, female 28.80/100 000, urban area 58.05/100 000, rural area 39.09/100 000), Chinese population standardized rate was 31.67/100 000, the world population standardized rate was 32.10/100 000, and the cumulative rate (0-74 years) was 3.87/100 000. The crude mortality rate was 35.65/100,000 (male 49.84/100,000, female 20.93/100,000, urban area 44.53/100,000, rural area 29.67/100 000), Chinese population standardized rate was 23.82/100 000, the world population standardized rate was 24.14/100 000, and the cumulative rate (0-74 years) was 2.69/100,000. Overall, the age-specific incidence and mortality of lung cancer in 2017 were at a low level in 0-44 years age group, and increased rapidly after 45 years age group, and reached a peak in 85 years age group. The incidence and mortality of lung cancer in males were higher than that in females. Although there were some differences in the incidence and mortality of patients with different ago range in urban and rural areas, the overall trend was similar.Conclusions:Lung cancer is the most common malignant tumor threatening the health of residents in Shanxi Province. Male, urban areas and middle-aged and elderly population are the focus of cancer prevention and control in Shanxi Province. Lung cancer prevention and control should be targeted carried out according to the differences between urban and rural areas and gender.

ABSTRACT
A Survey on the current general practice residency training was carried out in January 2018 among 1 114 general practitioners (GPs) who attended the standardized residency training program during 2014-2017. Basic information was obtained from the management department, other information was obtained from questionnaire. Total 1089 valid questionnaires were received with a retrieval rate of 97.8%. The survey showed that the ratios of male trainees, trainees aged 20-30 years and with bachelor degree were increasing during 2014-2017. The participants were more satisfied with the teaching quality in general hospital bases than that in community practice bases. Participants suggested to improve teaching quality, add teaching contents of humanity courses and TCM knowledge. Only14.4%(157/1 089) participants choose GPs as their career because liked this specialty. And 77.7%(846/1 089) GPs understood the main work of GP. There were 81.4%(887/1 089) participants wanted to work in; 77.7%(846/1 089) participants thought that the prospect of general practice would be excellent or good. Increasing income, professional promotion and a sense of social recognition were their wishes. Standardized residency training is crucial for general practitioners to upgrade their quality and competence, to improve training quality and to develop incentive policies are necessary.

ABSTRACT
Objective To study the difference on knowledge-attitude-practice about rational drug use in tumor patients between urban and rural in Shanxi province, and to provide evidence for further development on health education of rational drug use. Methods A questionnaire investigation was conducted among tumor inpatients in Shanxi Cancer Hospital from May 22 in 2014 to May 30 in 2014. Results A total of 990 tumor patients were involved, including 499 urban patients accounting for 50.4 % and 491 rural patients accounting for 49.6 %. The tumor patients′awareness rates of 'the purchase of antibiotics needs a prescription' in urban and rural areas were the highest, 74.9 % (374/499) and 67.0 % (329/491), respectively, and the awareness rates of 'the meaning of OTC on the medicine package' were the lowest, 22.0 % (110/499) and 18.1 % (89/491), respectively. 96.2%(480/499) urban and 92.7%(455/491) rural tumor patients had developed a correct attitude towards 'irrational drug use will affect health and even life-threatening' which ranked the highest, and the rates of correct attitude towards 'adverse drug reaction is the medical accident' were the lowest, 55.5 %(277/499) and 48.1 % (236/491), respectively. The correct behavior rates of 'read the drug instructions' in urban and rural tumor patients were the highest, 97.8% (488/499) and 95.1 % (467/491), respectively, and the correct behavior rates of 'the expired drug recovery to nearby regular pharmacy' were the lowest, 9.2 %(46/499) and 7.5 % (37/491), respectively. Conclusions The knowledge-attitude-practice about rational drug among urban and rural tumor patients in Shanxi province is not optimistic. It should be provided that individual health education in daily work in order to promote rational drug use, prolong survival time and improve the quality of life for tumor patients.
