Objective To explore the changes and significances of platelet granule membrane protein-140 (GMP-140),GMP-140 in plasma,PAdT and PAgT in patients with acute cerebral infarction.Methods The platelet GMP-140 was measured with enzyme-linked immunosorbent assay (ELISA) competitive method and GMP-140 in plasma by ELISA double antibody method in blood collecting in 3 d and 2 weeks after onset in large(n=22),small(n=25) size and lacuna (n=20) cerebral infarction groups.Results The platelet GMP-140,GMP-140 in plasma,PAdT and PAgT in large cerebral infarction group in 3 d after onset were much higher than control group (P<0.001),and the small size and lacuna groups were higher (P<0.05～0.001) than control but lower than large group (P<0.05).There was no differences between the small and lacuna groups (P>0.05).The PAdT and PAgT in 3 groups were higher (P<0.01).The platelet GMP-140 and GMP-140 in plasma in all 3 groups in 2 weeks after onset had been clearly lower but still higher than control group (P<0.05),the PAdT and PAgT were normal or even more lower.Conclusion Platelet activation was significant in different types acute cerebral infarction,the concentration of GMP-140 in plasma can reflect the degree of platelets activities more well and truly than PAdT and PAgT.

Aim To investigate the promoting apoptosis effect of artesunate( ART) on human colon cancer Lovo cells and its mechanisms. Methods MTT assay was performed to determine the anti-proliferative effect of artesunate. Flow cytometry assay and electron micros-copy( EM) were used to evaluate the apoptotic effect of artesunate. Luciferase reporter assay was introduced to measure the activation of Wnt/β-catenin pathway. Western blot was used to detect the pathway-related protein levels of β-catenin, GSK-3β,c-Myc and apop-tosis-related protein level of casepase-3 . Results Compared with the control group, the inhibitory rate of cell proliferation at 72 h and 320 μmol·L-1 ART was (78. 99 ± 1. 95 )% ( F =898. 301, P =0. 000 ); the cell apoptotic rate at 24 h and 160 μmol · L-1 ART was(19. 00 ± 0. 05)% and morphological signs of cell apoptosis were found by EM;the transcriptional activi-ty of TCF4/LEF at 24 h and 160 μmol·L-1 ART was (0. 36 ± 0. 30)%(F =470. 954,P <0. 01); the ex-pressions of caspase-3 and GSK-3β were significantly increased, whileβ-catenin and c-Myc were significant-ly decreased when treated with different concentrations of ART for 48 h ( P <0. 01 ) . Conclusion ART may significantly inhibit proliferation and promote apoptosis of Lovo cells probably by inactivating Wnt/β-catenin pathway.

Aim To investigate the effect of artesunate on the invasion of human colon cancer Lovo cells and the possible mechanisms. Methods After Lovo cells were treated with different doses of artesunate(20,80, 160 μmol·L - 1 ), the soft agar colony formation test was adopted to observe the anchorage-independent pro-liferation of Lovo cells. Transwell assay was used to determine the effect of artesunate on the invasion abili-ty of Lovo cells. And the protein expressions of HMGB1 and MMP-2 were investigated by western blot. Results Artesunate could significantly inhibit both proliferation and invasion ability of Lovo cells in a dose-dependent manner(P < 0. 01). The experimental group treated with artesunate significantly down-regula-ted the protein expressions of HMGB1 and MMP-2 compared with control group(P < 0. 05). Conclusion Artesunate could inhibit the invasion of human colon cancer Lovo cells by down-regulating HMGB1 and MMP-2 expressions.

Objective Intradialytic hypotension (IDH) is one of the common complications during hemodialysis,however its diagnostic criteria are highly controversial at present.In order to fully understand the prevalence of IDH in our center and figure out which diagnostic criteria is better for Chinese maintenance hemodialysis (MHD) patients,we choose several IDH definitions by reviewing published literatures and analyze their association with mortality.Methods The patients were recruited from Blood Purification Center of Ruijin Hospital undergoing hemodialysis during July 2012.Pre-,intra-and post-dialysis blood pressure were recorded.Patients' clinical characteristics,laboratory results and cardiac ultrasound results were collected.Based on several IDH definitions,we investigated the prevalence rate of IDH and its frequency among MHD patients.SPSS 23.0 was used to analyze data and conduct survival analysis.Results Totally 219 MHD patients underwent 16084 hemodialysis in 6 months.The prevalence rate,overall and individual frequency of IDH fluctuated between 45.21％-100.00％,4.64％-37.60％ and 0.00％-33.00％ respectively.For every IDH criteria,the patients were recruited into the group IDH(+) if they ever met the corresponding definition,otherwise the group IDH(-).Survival analysis found that IDH (the criteria of an absolute systolic blood pressure (SBP) ＜ 90 mmHg or with a decrease of SBP≥ 20 mmHg) could decrease the risk of patients' cardiovascular mortality but was not relevant to all-cause mortality.Further analysis showed these patients had better cardiac functions mainly reflecting in lower Pro-BNP (2880 ng/L vs 6909 ng/L),lower prevalence rate of left ventricular hypertrophy (52％ vs 83％) and higher left ventricular ejection fraction (65.0％ vs 62.5％) than IDH(-) patients.No correlation was found between other IDH criteria and mortality.Conclusions The prevalence rate,overall and individual IDH frequency of IDH are of high variability when diagnosed by different IDH criteria.All IDH episodes defined by our selected definitions are of no association with all-cause mortality.An absolute SBP ＜ 90 mmHg or with a decrease of SBP≥20 mmHg can decrease the risk of cardiovascular mortality due to their better cardiac function.Large scale researches should be conducted to find optimal IDH definition and explore the association of IDH and mortality.

ObjectiveTo investigate the prevalence of cholelithiasis in the employees of Kailuan Corporation and to provide a reference for effective preventive measures. MethodsA total of 101 510 in-service or retired employees of Kailuan Corporation were recruited. All of them completed checkups organized by Kailuan Corporation from June 2006 to October 2007. The cholelithiasis examination data of 1133 employees were lost and the data of 100 377 employees were finally included in the statistical analysis. Questionnaire survey, blood biochemical examination, and ultrasound examination of the gallbladder were carried out. According to the ultrasound examination results, the subjects were divided into cholelithiasis group and non-cholelithiasis group. Comparison of the means between the two groups was made by t-test and comparison of the incidence rates between the two groups was made by chi-square test. The risk factors for cholelithiasis were assessed using multiple logistic regression analysis. ResultsThere were 80 129 males and 20 248 females in the 100 377 subjects. Their ages ranged from 18 to 98 years (mean, 51.89±12.66 years). There were 98 109 subjects without cholelithiasis and 2268 subjects (2.3%) with cholelithiasis. The females had a significantly higher incidence of cholelithiasis compared with the males (2.5% vs 2.2%, χ2=4.60, P=0033). The incidence rate of cholelithiasis increased with age in both men and women. According to the result of logistic regression analysis, sex, age, body mass index, occupation, fasting plasma glucose, high-sensitivity C-reactive protein (hs-CRP), and cholecystitis were all risk factors for cholelithiasis and the odds ratios (95% confidence interval) of them were 0.765(0.687-0.853), 1.439(1.388-1493), 1.403(1.282-1.535), 0.821(0.706-0.955), 1.234(1.075-1.416), 1.080(1.022-1.142), and 12.519(10678-14678), respectively. ConclusionPeople with advanced age, female sex, obesity, hyperglycemia, high hs-CRP, cholecystitis, or unhealthy lifestyle have high risk of cholelithiasis.

Objective:To investigate the correlation between triglyceride glucose (TyG) index and severe hypertriglyceridemic pancreatitis (HTGP), and to provide assistance for early evaluation and clinical decision-making of HTGP.Methods:From January 2016 to December 2021, the clinical data of 770 patients diagnosed with HTGP at Sir Run Run Shaw Hospital, Zhejiang University School of Medicine were retrospectively collected. According to severity of pancreatitis, the patients were divided into mild acute pancreatitis (MAP), moderate severe acute pancreatitis (MSAP) and severe acute pancreatitis (SAP) groups, and the differences in TyG index among the 3 groups was compared. According to the quartile range of the TyG index, the patients were divided into TyG Q1, Q2, Q3 and Q4 groups, and the distribution of severity of pancreatitis in each TyG index quartile group was calculated. Kruskal-Wallis H test was used for statistical analysis. Spearman correlation analysis was used to analyze the correlation between TyG index quartile range and the severity of pancreatitis. Linear trend chi-square test was used to analyze the trend of SAP incidence among groups. Binary logistic regression was used to analyze the relationship between TyG index quartile range and the risk of SAP, and the trend test was also conducted. Results:A total of 770 patients with HTGP were included, among them 330 (42.9%), 268 (34.8%) and 172 (22.3%) were MAP, MSAP and SAP, respectively. The TyG indices of MAP, MSAP and SAP group were 11.8(11.3, 12.4), 12.5(11.9, 13.2) and 12.7(12.1, 13.4), respectively, and the differences among the 3 groups were statistically significant ( H=121.77, P<0.001). The TyG index was 12.21 (11.57, 12.94) in the 770 patients. There were 192, 193, 193 and 192 patients enrolled in TyG Q1(TyG index <11.57)、 Q2(TyG index ranged from 11.57 to <12.21)、 Q3(TyG index ranged from 12.21 to <12.94) and Q4(TyG index≥12.94) group, respectively.The correlation test showed that the difference between TyG quartile range and the severity of pancreatitis was statistically significant ( ρ=0.372, P<0.001). The incidence of SAP in TyG Q1, Q2, Q3 and Q4 group was 10.9%(21/192), 14.5%(28/193), 27.5%(53/193) and 36.5%(70/192), respectively. The trend test of SAP incidence among the TyG gruops was statistically significant ( χ2 =44.33, P<0.001). After adjusting for confounding factors, taking the TyG Q1 group as a reference, the OR values of SAP risk (95% confidence interval) of the TyG Q2, Q3 and Q4 groups were 1.250 (0.619 to 2.524), 2.882 (1.506 to 5.514) and 6.660 (3.456 to 12.836), respectively, and the trend test of SAP risk showed a significant difference ( OR=2.508, 95%confidence interval 1.883 to 3.341, P<0.001). Conclusions:There is a correlation between TyG index and severity of pancreatitis in patients with HTGP. As the TyG index increases, the risk of SAP increases in HTGP patients. TyG index may be an early predictor of severe HTGP.

Objective: To account the direct cost of uterine cervix carcinoma treatment in China and to explore the related factors which influence the direct financial burden of the disease. Methods: Data was collected through the medical record system and telephone interviews in 14 county-level hospitals and 9 provincial and municipal hospitals from 14 provinces/municipalities enrolled in the Chinese National Health Industry Research Project in 2015. The direct financial burden of uterine cervix carcinoma treatment consisted of the direct medical cost and the direct non-medical cost of treatment in different pathological cervical cancer stages and precancerous lesions. Multiple liner regression method was used to analyze the factors affecting the costs. Results: The age of the 3 246 patients was (46.40±10.43) years, including 2 423 patients from provincial and municipal hospitals and 823 patients from county-level hospitals. The direct financial burden for one patient of pathological uterine cervix carcinoma stage or precancerous lesion ranged from 10 156.3 yuan to 75 716.4 yuan in provincial and municipal hospitals, and for patients from county-level hospitals, the cost was between 4 927.9 yuan and 47 524.8 yuan per person. There was a wide gap between the direct financial burden of patients in different disease stages. The direct financial burden of patients with precancerous lesions ranged from 4 927.9 yuan per person to 11 243.0 yuan per person, as for patients of pathological uterine cervix carcinoma stages, the direct financial burden was between 29 274.6 yuan and 75 716.4 yuan per person. The factors which influence direct financial burden would include: the levels of the hospital, pathological period, medicare reimbursement, days of treatment, and the methods of treatment (P<0.001). Conclusion The direct financial burden of diseases in patients with pathological uterine cervix carcinoma stage or precancerous lesion differed in different levels of hospital and pathological periods. In addition, medicare reimbursement, days of treatment, and the methods of treatment all had impact on it.

Objective To reveal pathogenesis and etiology in adrenal incidentaloma. Methods The clinical data of 116 patients with adrenal incidentaloma from January 1, 2015 to January 1, 2017 were retrospectively analyzed. Results In 116 patients with adrenal incidentaloma, 49 cases (42.2％) were male and 67 cases (57.7％) were female; there were 14 cases (12.1％) aged from 20 to 40, 63 cases (54.3％) aged from 40 to 60, and 39 cases (33.6％) > 60 years. Forty-three patients (37.1％) were found by health examination, 26 patients (22.4％) were found because of hypertension, 27 patients (23.3％) were found by CT detection because of other diseases, and 20 cases (17.2％ ) were found because of other reasons. The result of endocrine function examination showed that nonfunctioning adrenal tumor was in 56 cases (48.3％); functional adrenal tumor was in 44 cases (37.9％), among whom primary aldosteronism was in 27 cases, Cushing syndrome was in 10 cases, and pheochromocytoma was in 7 cases;nonfunctioning non- adenoma was in 16 cases (13.8％ ). Conclusions It is frequent that the adrenal incidentaloma is found by health examination. The patients with adrenal incidentaloma should examine the endocrine function and identify the benign or malignant. And if necessary, surgical treatment should be performed.

Objective: To analyze Internet behaviors of children and adolescents and their influencing factors, and to provide scientific basis for health education guidance and prevention measures. Methods: A stratified cluster sampling method was used. From January to June 2019, 30 955 primary school students in 16 provinces (municipalities), from eastern, central, and western economic zones of China were selected to conduct a questionnaire survey, regarding general demographics, diet and exercise, tobacco, alcohol and sleep, Internet and electronics usage, etc. Results: Among them, 43.1% of students had never been online with girls (44.7%) higher than boys (41.8%)(χ2=21.04, P<0.01); 1.3% of students reported online time for more than 4 hours a day, boys were significantly higher than girls(χ2=15.87, P<0.01); Internet addiction was detected in 2.4% of elementary school students, with boys (3.0%) higher than girls(1.7%)(χ2=331.77, P<0.01), and the trend increases with grade. With sixth grade (3.3%) were significantly higher than children from the first grade (0.8%) and other grades(χ2=163.96, P<0.01). Children’s tendency to Internet addiction was 11.9%, of which boys were 13.0% and girls were 10.6%, boys were significantly higher than girls(χ2=117.66, P<0.01). Pearson correlation analysis revealed that, after controlling gender age, boarding school, family relationship, single parents and regrouped families, smoking, drinking sugary drinks, eating fried foods, and left-behind were positively related to Intenet addiction(r=0.06, 0.07, 0.27, 0.44, 0.07, 0.11, 0.09, P<0.01), while medium and high intensity sports, effective physical education, health education in school, AIDS education and parental restrictions on TV and computer games, were negatively associated with internet addiction(r=-0.74, -0.65, -0.04, -0.05, -0.63, P<0.01). Conclusion The internet addiction of Chinese primary school students is common and increases by year. High-intensity, high-density sports, effective physical education, and health education could help prevent Internet addiction among children.
