This article,in view of the research status and development tendency of hospital core competence,introduced the index selection process and constructed the evaluation index system of core competence.This system comprises 3 level-1 indexes (social reputation,hospital health resources and development potential)and 9 level-2 indexes,with recommendations on improvements of the existing system.

Objective To explore the expressions of miR-221 and miR-222 in papillary thyroid carcinoma (PTC),and relativi-ties with clinical pathological features.Methods Samples from patients of PCT (43 cases),nodular golter(21 cases),and para-carcinoma thyroid tissues(14 cases),78 cases in total (from 06/2015 to 05/2016,Shaanxi Provincial People’s Hospital) were collected.Real time-PCR tests were carried out,then analyzed in relation to clinical pathology features,and statistical a-nalysis was used to evaluate the results.Results The expressions of miR-221 and miR-222 were significantly higher in PTC (11.54±3.37,10.67±2.45)than in nodular golter (3.21±1.12,2.89±1.23)and normal thyroid tissue (2.02±0.76, 1.98±0.34)(t=3.62,3.25;3.27,3.01,all P<0.05),which were significantly related with Regional lymph node metasta-sis,tumor invasion coated,distant metastasis and clinical stage (P<0.05),while not related with the gender,age,or size of the tumor of the patients (P>0.05),and no differences were found in nodular golter and in normal thyroid tissue (t=0.91, 0.79,P>0.05).Conclusion miR-221 and miR-222 could be considered as a specific molecular marker of PTC,may play an important role in the diagnosis and treatment on PTC.

Objective To describe the status of prevalence,awareness,treatment,and control of hypertension among the residents in severe historical endemic areas of Keshan Disease in Heilongjiang Province,and to provide scientific evidence for prevention and control of hypertension.Methods In December 2015,Yongjin,Yongli groups of Yongjin Village,and Fengnian,Fengtian,Fengfu groups of Fengnian Village in Fanrong Township,Fuyu County,Qiqihaer City,Heilongjiang Province were selected via the cross-sectional method.The residents aged 18 years or older were surveyed as respondents by cluster sampling.Demography,risk factors,hypertension related information were collected through questionnaire survey.Blood pressure,height and weight were measured through physical examination.Blood pressure measurement was conducted with Omron HEM-1020 electronic sphygmomanometer,the diagnostic criteria was Chinese Guidelines for Prevention and Treatment of Hypertension (revised in 2010).Results Totally 683 residents were surveyed,the valid participants were 669,the prevalence of hypertension was 49.2％ (329/669),the standardized prevalence was 37.9％,the prevalence of men [58.0％ (164/283)] was higher than that of women [42.7％ (165/386),x2 =15.103,P ＜ 0.01],the prevalence increased with increasing age (total,men,women:x2tendency =9.044,4.560,7.789,all P ＜ 0.01).The awareness of hypertensive patients was 60.8％ (200/329),the standardized awareness was 41.2％,the awareness of men [54.3％ (89/164)] was lower than that of women [67.3％ (111/165),x2 =5.836,P ＜ 0.05],the awareness of hypertensive patients increased with increasing age (total,men,women:x2tendency =3.638,2.686,2.419,all P ＜ 0.05).The treatment of hypertensive patients was 51.1％ (168/329),the treatment of men [43.9％ (72/164)] was lower than that of women [58.2％ (96/165),x2=6.711,P ＜ 0.05],the treatment of hypertensive patients increased with increasing age (total,men,women:x2tendency =4.422,2.704,3.633,all P ＜ 0.01).The control rate of hypertensive patients was 5.5％ (18/329),the control rate among the treatment was 10.7％ (18/168).Conclusions The standardized prevalence of hypertension among the residents of the severe historical endemic areas of Keshan disease in Heilongjiang Province is higher than the national average (25.2％),the standardized awareness is lower than the national average (46.5％),the treatment and the control are low.We should pay more attention to the hypertension in the severe historical endemic areas of Keshan disease.

To assess the influence of different sampling methods on Human Amniotic Fluid (HAF) during metabonomics analysis, and to establish a metabolite profile database for normal human amniotic fluid, four experimental groups (the group of freeze-drying, of freeze-thawing, of storage at -20 degrees C, and of keeping in room temperature) and a control group were investigated by use of 1H-NMR spectroscopy, respectively; the data of H-NMR spectroscopy was treated by principal components analysis (PCA). The results showed that, by comparison with the control, there were distinct differences in the experimental groups except the group of storage at -20 degrees C. Therefore, It is possible to use 1H-NMR-based metabonomics technique for analysis of HAF; moreover, during the tests, careful treatments of HAF should be institued to minimize the influence on the samples.

Objective:To study the population distribution of Pomacea spp. in Shandong Province and the risk of angiostrongyliasis cantonensis in the local population, and to provide a basis for scientific prevention and control of related diseases. Methods:From July to December 2021, Yanzhou District of Jining City, Ningyang County of Taian City, and Dongying District of Dongying City were selected as surveillance sites to investigate the population and distribution range of Pomacea spp., live snail samples were collected for morphological and genetic identification, and Pomacea spp. infected with the larva of Angiostrongylus cantonensis was detected by lung test. At the same time, sentinel hospital case surveillance was carried out in Yanzhou District, Jining City, and questionnaire was used to study the local residents' awareness of angiostrongyliasis cantonensis and their personal health behaviors. Results:A total of 312 live snail samples were collected. After morphological identification, they were all Pomacea spp.. After gene sequencing, two populations of Pomacea canaliculata and Pomacea maculata were found. No positive snails infected with Angiostrongylus cantonensis were found. A total of 126 patients with headache as the main neurological symptom were admitted to the sentinel hospital, but there were no monitoring cases that met the inclusion criteria. Among the survey population, 48.38% (134/277) of the respondents had heard of angiostrongyliasis cantonensis, 44.77% (124/277) knew that eating Margarya melanioides might cause angiostrongyliasis cantonensis, and 83.39% (231/277) had no related unhealthy eating behavior. Conclusion:Pomacea spp. is found and reported for the first time in Shandong Province, and there is a risk of population infection with angiostrongyliasis cantonensis.

Objective To explore the temporal and spatial distribution characteristics of air pollutants PM_2.5, PM₁₀, SO₂, CO, and NO₂, and their effects on acute cerebrovascular diseases in Jining City. Methods The data of patients with acute cerebrovascular disease treated in a 3A hospital in Jining from October 1, 2017, to November 31, 2019, were retrospectively collected. Combined with the air pollution data of 29 air quality monitoring stations in Jining City, the Kriging interpolation model was used to analyze the overall situation of air pollution in Jining. On this basis, the relationship between air pollution and acute cerebrovascular diseases in Jining City was analyzed. Results In Jining City, the incidence of acute cerebrovascular disease in male was higher than that in female, and the incidence in rural areas was significantly higher than that in urban areas. The spatial distribution showed a trend of gradual accumulation from southeast to northwest. The daily average concentrations of PM2.5 and PM10 were higher in winter and spring than in summer and autumn. The results of Kriging interpolation analysis showed that the concentrations of these air pollutants formed aggregation points in varying degrees. The spatial distribution of acute cerebrovascular disease patients in Jining City was highly consistent with the spatial distribution of air pollutant concentrations. Spearman correlation analysis showed that CO, SO₂, and NO₂ were positively correlated with the incidence of acute cerebrovascular disease, while the correlation between PM_2.5 and PM₁₀ and the incidence of acute cerebrovascular disease was not significant. Conclusion Some air pollutants such as CO, SO₂, and NO₂ have a positive correlation with the incidence of acute cerebrovascular disease, and the prevalence has a certain population and regional distribution. In the future work of cerebrovascular disease prevention, personal protection should be done according to local conditions and living environment of specific people.
