Purpose To observe the functional expression of calcium sensing receptor ( CaSR) in human gastric cancer SGC-7901 cell line, the effect of CaSR on intracellular calcium, cell proliferation and migration of SCG-7901. Methods The expression and distribu-tion of CaSR were detected by Western blotting and immunofluorescence observation in SGC-7901. The intracellular concentration of free calcium ( [ Ca2+] i ) was determined by confocal laser scanning microscopy. MTT, flow cytometry and scratch test were used to an-alyze the impact of CaSR the proliferation and the migration capabilities of SGC-7901 cell. Results CaSR protein was expressed in SGC-7901. Extracellular calcium or calindol significantly increased the expression of [Ca2+]i, CaSR and E-cadherin;In addition, the migration capabilities were decreased. Conclusion CaSR is expressed in SGC-7901. The activation of CaSR induces the expression of E-cadherin, and decreases migration ability.

Objective:To construct evaluation index system of traditional Chinese medicine (TCM) nursing quality of tuberculosis bases on "structure-process-result" three-dimensional quality structure model as a framework so as to provide evaluation standards and basis for tuberculosis TCM nursing quality management.Methods:By the convenient sampling method, 12 doctors and nurses in tuberculosis department from 2 third-class grade-A hospitals of Traditional Chinese medicine or integrated traditional Chinese and western medicine hospital in Zhejiang province were selected from March 2019 to April 2019 in order to conduct semi-structured interviews. 26 nursing experts were selected for expert consultation. Through literature research, semi-structured interview, Delphi method and superiority chart, the evaluation index system of TCM nursing quality of tuberculosis and the weight of each index were established.Results:The effective recovery rates of the letter questionnaires were 84.62% (22/26) and 77.27% (17/22) , the expert authority coefficients were respectively 0.831 and 0.843 and the Kendall's W were respectively 0.236 and 0.335. The eventually established evaluation index system of TCM nursing quality of tuberculosis included 3 first-level indicators, 16 second-level indicators and 56 third-level indicators. Conclusions:In this study, the evaluation index system of TCM nursing quality of tuberculosis constructed by various methods is more scientific, complete and reliable, which can provide references for the evaluation of TCM nursing quality of tuberculosis and the formulation of standard.

Objective:To establish a predictive equation for the osmolarity of parenteral nutritional prescription in China.Methods:From July 2019 to September 2019, 2 480 individualized samples of 328 different parenteral nutritional prescriptions (adult) of Peking Union Medical College Hospital were collected, and the osmolarity of parenteral nutritional solution samples was determined by a freezing point reduction method. Pearson χ2 test and a multiple linear regression analysis were utilized to establish a prediction equation for the osmolality of parenteral nutritional solution. Results:The average osmolarity of parenteral nutritional prescription was (1 164.20 ± 252.59) mOsm/kg, and the best fitting equation was (9.66A+ 7.88G+ 3.52F+ 36.4Na+ 27.55K+ 3.38P+ 7.46W-250)/V.Conclusion:The osmolarity is determined accurately and effectively by the fitting equation, which provide a benefit reference for the formulation, review and selection of clinical parenteral nutrition prescription especially in China.

Objective:To investigate the features, changing trend, and rules of pneumoconiosis in Jiangsu Province, China, as well as the health status of patients with pneumoconiosis.Methods:From July to October 2019, the patients with pneumoconiosis, reported up to the end of 2018 in Jiangsu Province, were enrolled as respondents, and follow-up and retrospective investigation were performed. A total of 24405 patients with pneumoconiosis were investigated, and related data were collected from the monitoring system of cause of death for residents, pneumoconiosis network reporting system, occupational disease diagnosis institution, management institutions for the reporting of occupational diseases, and related residents' committee or village committee. The patients with pneumoconiosis, who had been reported, were followed up by telephone or on-site visit to obtain the information on their conditions. A descriptive analysis was performed for age of onset, working years, sex, category of industry, type of pneumoconiosis, annual disease onset, geographic distribution, and medical security.Results:Among the 24405 patients, a male/female ratio was 16.81∶1. Of all 24405 patients, 15948 (65.35%) had stage 1 pneumoconiosis, 5289 (21.67%) had stage 2 pneumoconiosis, and 1637 (6.71%) had stage 3 pneumoconiosis. The mean working years for dust exposure was 16.25±9.95 years for all patients, and the mean working years for dust exposure was 15.80±9.95 years for patients with stage 1 pneumoconiosis, 17.82±9.80 years for patients with stage 2 pneumoconiosis, and 16.31±9.90 years for patients with stage 3 pneumoconiosis. The highest number of cases of pneumoconiosis was reported in Wuxi (5744 cases, accounting for 23.54%) , followed by Zhenjiang (4160 cases, accounting for 17.05%) , Xuzhou (3851 cases, accounting for 15.78%) , Yancheng (3340 cases, accounting for 13.69%) , and Suzhou (2948 cases, accounting for 12.08%) . Major types of pneumoconiosis included silicosis (15392 cases, accounting for 63.07%) and coal workers' pneumoconiosis (5253 cases, accounting for 21.52%) . In this survey, 21115 completed follow-up, among whom 15924 survived and 5191 died, 15924 patients with pneumoconiosis survived, among whom 7461 (46.85%) had an age of ≥70 years and 2515 (15.79%) were exposed to dust for 5-9 years. The industries involved were mainly coal mining and washing industry (5687 cases, accounting for 35.71%) and public management, social security, and social organization (3349 cases, accounting for 21.03%) ; in terms of security, 7999 patients (50.23%) were covered by occupational injury insurance, 946 (5.94%) were compensated by employers, 4537 (28.49%) were covered by basic medical insurance for urban and rural residents, 1590 (9.98%) were covered by critical illness insurance, and 5458 (34.28%) were covered by other types of social security, such as medical assistance and poverty relief.Conclusion:Silicosis and coal worker's pneumoconiosis are the key points for the prevention and treatment of pneumoconiosis in Jiangsu Province, and supervision should be strengthened for industries and regions with serious dust hazards.

Objective: To explore the improvement rate of liver fibrosis in patients with chronic hepatitis B virus infection who received entecavir alone or in combination with anluohuaxianwan for 78 weeks. Methods: Patients with chronic HBV infection were randomly treated with entecavir alone or in combination with anluohuaxian for 78 weeks. Ishak fibrosis score was used for blind interpretation of liver biopsy specimens. The improvement in liver fibrosis condition before and after the treatment was compared. Student's t test and non-parametric test (Mann-Whitney U-Test and Kruskal-Wallis test) were used to analyze the measurement data. The categorical variables were analyzed by Chi-square test method and Spearman’s rank correlation coefficient was used to test bivariate associations. Results: Liver fibrosis improvement rate after 78 weeks of treatment was 36.53% (80/219) and the progression rate was 23.29% (51/219). The improvement of liver fibrosis was associated to the degree of baseline fibrosis and treatment methods (P < 0.05). The improvement rate of hepatic fibrosis in patients treated with anluohuaxianwan combined with entecavir at baseline F < 3 (54.74%, 52/95) was significantly higher than that in patients treated only with entecavir (33.33%, 16/48), P = 0.016 and the progression rate of hepatic fibrosis (13.68%, 13/95) was lower than that in patients treated alone (18.75%, 9/48), P = 0.466. In patients with baseline F < 3, the proportion of patients with improved and stable liver fibrosis in the combined treatment group (68.1%, 32/47) was higher than that in the treatment group alone (51.7%, 15/29). Conclusion Combined anluohuaxianwan and entecavir treatment can significantly improve the improvement rate of liver fibrosis in patients with chronic hepatitis B virus infection. Furthermore, it has the tendency to improve the stability rate and reduce the rate of progression of liver fibrosis.
