ObjectiveTo study the relationship between fasting plasma glucose (FPG) level and the first cerebral infarction event in the population with diabetes.Methods This was a prospective cohort stndy.8 306 diabetic subjects who determined FPG ≥ 7.0 mmol/L or treated with insulin or hypoglycemic drugs and FPG ＜7.0 mmool/L as the observation population and were followed-up for (48.01 ± 3.14) months.During the course,cerebral infarction events were determined every 6 months.Results( 1 ) By the end of following-up,with the increasing levels of the baseline FPG,the total cholesterol (TC),triglyceride (TG) levels were gradually increased in the diabetic population,the differences were significant [ TC:( 4.93 ± 1.15,5.10 ± 1.20,5.15 ± 1.28,5.33 ± 1.35 ) mmol/L,TG:( 1.70 ± 1.26,1.83 ± 1.29,2.18 ± 1.76,2.41 ± 2.08 ) mmol/L,P＜0.05 ] ; the plasma low density lipoprotein-cholesterol (LDL-C),systolic blood pressure ( SBP),diastolic blood pressure ( DBP),and body mass index (BMI) levels were also increased significantly ( P＜0.05 ).(2) The ineidence of cerebral infarction event in the group of patients with 7.0 mnol/L ≤ FPG ＜ 9.0 mmol/L was the lowest,the differences were significant ( 2.1％,P ＜0.01 ).Compared with the group of 7.0 mmol/L≤ FPG＜9.0 mmol/L,after adjusting for age,sex,BMI,SBP,DBP,TC,TG,low density lipoprotein-cholesterol,high density lipoprotein-cholesterol,smoking,diabetic duration and treatment,the relative risk for cerebral infarction events were 1.85 (95％ CI 1.09-3.15,P＜0.05) and 1.54 (95％CI 1.16-2.05,P ＜ 0.01 ) for those groups with 6.1 mmol/L ≤ FPG ＜ 7.0 mmol/L and FPG ≥ 9.0 mmol/L respectively.ConclusionThe risk of new in cidence of cerebral infarction events seems to be the lowest in the group of diabetic patients whose FPGs are wihin 7.0-9.0 mmol/L range.

Objective To evaluate the growth inhibition of human gastric carcinoma cell lines SGC 7901 in vitro and the expression of bcl-2, bcl 2l12 and bax with docosahexaenoic acid (DHA) and 5-fluorouracil (5-FU). Methods The effect of DHA and 5-FU was measured by trypan blue, and the interaction between two agents was judged by combination index (CI). Cells were observed by inverted microscope. Flow cytometry was used for analysis of apoptosis by PI staining and Annexin-V/PI. RT-PCR was used to analyze the levels of bcl-2, bcl 2l12 and bax mRNA. Results DHA significantly inhibited the growth of SGC 7901 cells in a dose- and time-dependent way ( P < 0. 05 ), the IC50 of 24 h and 48 h was 67. 81 μg/ml and 45.76 μg/ml, and a strong synergism was found in the combination of DHA and 5-FU (CI < 1 ,P <0. 01 ). Treated by DHA and 5-FU for 48 h, cells became sparse under inverted microscope. DHA or 5-FU was able to induce apoptosis and the effect became even more significant by the combination of DHA and 5-FU. Cells were holted in phase of G01/G1 and S. RT-PCR showed that DHA or 5-FU down-regulated the expression of bcl-2 and bcl 2l12 mRNA, while bax mRNA expression was not downregnlated. Conclusions DHA could inhibit the growth of gastric carcinoma cells, DHA and 5-FU had synergetic effect in the inhibition of the cells growth and blockage of the cell cycles possibly by down-regulating the expression of bcl-2 and bcl 2l12.

Objective:To evaluate the diagnostic value of endoscopic ultrasonography (EUS) in colorectal submucosal lesions, and provide evidence for clinical diagnosis and treatment strategies.Methods:A retrospective analysis was performed on data of 229 patients with colorectal submucosal lesions discovered by electronic colonoscopy and EUS. The diagnosis was confirmed by pathology. The location, type, EUS features of lesions and the coincidence rate of EUS and histopathological diagnosis were analyzed.Results:Colorectal submucosal lesions were common in the rectum (44.98%, 103/229) and ascending colon (15.28%, 35/229). Lipoma was the most common pathological type of colorectal submucosal lesions (34.93%, 80/229), which was commonly located in transverse colon (22.50%, 18/80) and ascending colon (20.00%, 16/80). Neuroendocrine tumor was the second one, accounting for 33.63% (77/229), and was commonly located in rectum (96.10%, 74/77), followed by cyst (18.78%, 43/229). Under EUS, 229 cases of lesions originated from submucosa in 215 cases, muscularis mucosa in 11 cases, and muscularis propria in 3 cases. The overall coincidence rate of EUS and pathological diagnosis was 89.08% (204/229). The coincidence rate of EUS diagnosis was 100.00% (80/80) for lipoma, 5/5 for air-cyst, 3/3 for intestinal stromal tumor, 81.82% (72/88) for neuroendocrine tumor, 89.13% (41/46) for cyst, 1/4 for leiomyoma, 2/5 for lymphangioma, and granulosa cell tumor and neurofibroma were both 0.Conclusion:EUS has a more accurate diagnosis of the origin, echogenicity and pathological properties of colorectal submucosal lesions, but it has certain limitations for the diagnosis of rare tumors such as granulosa cell tumor and neurofibroma.

Objective: To explore prevalence and associated factors of neglect among left-behind middle school students in undeveloped area of Guangdong, and to provide scientific basis for effective intervention measures. Methods: A total of 1 105 middle school students were selected from Yangjiang and Qingyuan by random cluster sampling, neglect and left-behind was assessed by a self-reported questionnaire. Results: The prevalence of neglect was 70.9% among left-behind middle school students aged 11-17 years in Yangjiang and Qingyuan areas. Univariate analysis suggested that high parental education, democratic and strict parenting, and frequent contacts with parents associated with low rate of neglect (P<0.05). After adjusted for gender, parental education, parenting style, contact frequency, Logistic regression analysis revealed that parenting discipline(rough, cold, capricious)(OR=2.01, 95%CI=1.23-3.26), contact with parents more than once every two weeks (OR=1.75, 95%CI=1.12-2.72) , peer or self-care (OR=1.85, 95%CI=1.04-3.30) were positively associated with neglect, while higher mother education was negatively associated with neglect. Conclusion The prevalence of neglect is high among left-behind students in Yangjiang and Qingyuan, which deserves further attention from family, community, school and government to promote healthy development.

Objective Observed the characteristics and influence factors of blood pressure circadian rhythm in continuous ambulatory peritoneal dialysis patients.To investigate the effect of residual renal function and cardiac function.Methods Prospectively collected 120 cases of continuous ambulatory peritoneal dialysis from June 2016 to March 2017 in Tangshan renal medicine dialysis centers,who combined with hypertension were treated with peritoneal dialysis for more than 3 months.According to the dynamic monitoring blood pressure circadian rhythm of blood pressure,120 cases were divided into the normal rhythm of blood pressure and the abnormal blood pressure rhythm group.Collected medical history;Tested related test index respectively;Cardiac ultrasound.According to the formula to calculate residual renal function,left ventricular mass index,Eingabe/Ausgabe,Ejection Fraction.Univariate and multivariate unconditional logistic regression analysis was used to analyze the risk factors of circadian rhythm of blood pressure.Stepwise multiple linear regression analysis was used to analyze the risk factors of residual renal function and cardiac function.Results CAPD patients with normal blood pressure rhythm in 14 cases(11.7％),abnormal blood pressure rhythm in 106 cases(88.3％),Among them,non dipper blood pressure accounted for 75 cases(62.5％).Single factor and multiple factors unconditioned logistic regression analysis revealed that after the comparison of gender and age,Risk factors for abnormal circadian rhythm of blood pressure were:UA(OR=1.197,95％CI:1.099-1.441),CRP(OR=1.170,95％CI:1.061-1.331),RRF(OR=1.389,95％CI:1.160-1.779).Using stepwise multiple linear regression analysis of dangerous factors affecting residual renal function and cardiac function,we found:Residual renal function negatively correlated with left ventricular myocardial mass index,systolic blood pressure drops at night rate,and ultrafiltration volume;LVMI (cardiac function) Positively correlated with 24 h average systolic blood pressure,and negatively correlated with systolic blood pressure drop ratio and residual renal function at night.Abnormal circadian rhythm of blood pressure may lead to the decline of residual renal function and cardiac function.Conclusions UA,CRP and RRF may affect the CAPD patients blood pressure circadian rhythm.At the same time,abnormal circadian rhythm of blood pressure may lead to the decline of residual renal function and cardiac function.Therefore,pay attention to the monitoring and control of ABPM,can better protect the residual renal function and improve cardiac function,so as to prolong and improve the survival time and quality of life of patients with CAPD.

Objective:To explore the effect of a health management model constructed based on reflexive reconstruction strategy in patients with acute pancreatitis.Methods:Totally 150 patients with acute pancreatitis admitted to Jincheng No.2 People's Hospital from January 2020 to January 2022 were selected by convenience sampling. They were divided into observation and control groups, each containing 75 individuals, using a random number table. Patients in the observation group were managed using a health management model under the reflexive reconstruction strategy, while patients in the control group followed a conventional health management model.Results:Six months post-intervention, the total score of health behavior capacity and the scores of its four dimensions, as well as the score indicating the level of health knowledge mastery in the observation group, were significantly higher than those in the control group ( P<0.01). Furthermore, the recurrence rate of acute pancreatitis in the observation group was 5.3% (4/75), which was lower than 16.0% (12/75) observed in the control group, demonstrating a statistically significant difference (χ 2=4.478, P=0.034) . Conclusions:The health management model developed based on the reflexive reconstruction strategy can enhance the health behavior capacity and the level of health knowledge mastery in patients with acute pancreatitis and reduce the recurrence rate of acute pancreatitis. It can serve as a reference for the continuous improvement of clinical health care management programs.
