Objective To investigate the clinical significance of gastric cracks by investigating the relationship between stomach cracks under gastroscopy and H.pylori infection as well as its pathological manifestation,in order to improve the detection rate of H.pylori.Methods Gastroscopy patients were enrolled as our subjects excluding those with tumors,major diseases and under 18 years old.Mucosal biopsies were obtained from the lesser curvature of antrum and the greater curvature of body in each patient,then by HE staining,pathological and HP examination.The information including the pathological diagnosis,HP antibody,rapid urease test,endoscopic diagnosis and endoscopic gastric body cracking phenomenon were collected from all patient.H.pylori positivity was defined as a patient who showed two or more positive results in the Rapid Urea's Test,pathohistological examination and H.pylori antibody detection.Results (1) 437 patients with gastroscopy were included between December 2009 and December 2011,among whom 210 were male and 227 were female.There were 32 cases with gastric ulcer,59 cases with duodenal ulcer,51 cases with duodenitis,62 cases with reflux esophagitis,and 276 cases with chronic gastritis.(2) H.pylori distribution in stoma of all patients:160 of 437 patients(36.61％) are H.pylori positive,of which 68.75％ (110/160) was found H.pylori positive in both of gastric antrum and body,25.63％ (41/160) was H.pylori positive only in antrum,and 3.13％ (5/160) was H.pylori positive only in the body of stomach.(3)Relationship between the presence of cracks in gastric body and H.pylori infection:the H.pylori positivity was 62.58％ (97/155) and 22.34％ (63/282) respectively in the group with or without the presence of cracks in body.Cracks in gastric body examined by gastroscopy was related to H.pylori infection(x2 =69.788,P =0.000).(4) Relationship between the presence of cracks in gastric body and patho-histology:the presence of cracks in gastric body was related with severity of gastric inflammation by Wilcoxon rank sum test (P ＜ 0.0001),while there was no relationship between gastric body cracks and atrophy,intestinal metaplasia and atypical hyperplasia(P ＞ 0.05).(5) Relationship between the presence of cracks in gastric body and diseases:the presence of cracks in body was related with duodenitis,bile reflux under gastroscopy while there was no difference among in gastric body and gastric ulcer,esophagitis and chronic gastritis in terms of cracking appearance (P ＞ 0.05).Conclusion Our finding showed that cracking appearance in the gastric body is related with severity of inflammation in gastric mucosa bile reflux and duodenitis,suggesting that it can be one of the gastroscopic manifestations of more severe gastritis.

Objective To investigate the influence of pinealectomy(Px)and melatonin (MLT) supplementation on CD4~+CD25~+Treg cells development and Foxp3 expression in rat thymus. Methods One hundred and twenty clean-grade male SD rats were divided into five groups: normal control group, sham pinealectomized group, pinealectomized group, Px +7.5 mg/(kg·d) MLT group, Px +15 mg/(kg·d) MLT group, and the thymus were taken out at the 4th week and the 8th week;Flow cytometric analysis was used to analyse the number of double positive cells in the thymus and peripheral blood;Semiquantitative RT-PCR and immunohistochemistry were applied to analyse Foxp3 expression of rat thymus. Results There was no difference of the number of CD4~+CD25~+ Treg cells in rat thymus between Px and normal/sham group, and the number increased dependently on time and dose after MLT supplementation. In rat peripheral blood the double positive cells significantly increased in models of Px at the 4th week, and then backed to normal level after MLT supplementation. The results showed no significant changes in all groups at the 8th weeek;At the 4th weeks, Foxp3 expression increased in the thymus of Px rats compared to nomal/sham group, which returned to normal level after MLT supplementation. On the other hand, Foxp3 expression showed no significant difference in all groups at the 8th weeek.Conclusion Px made no difference between the development of CD4~+CD25~+Treg cells in rat thymus, but resulted in significant increase of thymic output and Foxp3 expression. All the effects disappeared at the 8th week. MLT supplementation could reverse the abnormity.

Objective To study the effect of pinealctomy and melatonin on the cell cycle distribution during T cell development in thymus. Methods SD rats were divided into 5 groups:normal controls,sham-operated controls,pinealectomy,pinealectomy+melatonin injection 7.5 mg/kg; and pinealectomy+melatonin injection 15 mg/kg.The animals were sacrificed at 4 or 8 weeks after operation.cycilnA +and cyclinE +T cells in thymus were dyed with immunocytochemical ABC methods, measured by computer image analysis.Cell cycle analysis was performed by flow cytometry.The expression of cyclin-dependent kinase inhibitor 1? was tested by RT-PCR method. Results The effect of pinealectomy on the expression of cyclinE was stronger than that of cycilnA. Pinealectomy promotes the synthesis of cyclinE in thymus.The percentage of G-0/G-1 phase cells was decreased and G-2/M phase cells was increased.These would be convalescente by supplement with melatonin,but the reaction to melatonin was differencet in thymus cortex and in medulla.Melatonin enhanced the expression of cyclin-dependent kinase inhibitor 1? in thymus.Conclusion Pinealectomy influences notably the T cells development in thymus.Rejuvenation of degenerative thymus could be observed by melatonin administration.

Objective:To investigate atrial fibrillation patients′illness perception during the blanking period after pulmonary vein isolation (PVI) and to analyze its influencing factors, so as to provide a reference for improving patients′cognition of the disease and speeding up the rehabilitation process.Methods:This study was a cross-sectional survey. Convenience sampling method was adopted to select 320 patients with atrial fibrillation who were reexamined in the outpatient department during the blanking period after PVI from Affiliated Hospital of Qingdao University from Auguest 2022 to May 2023 as the research subjects. The General Information Questionnaire, the Brief Illness Perception Questionnaire (BIPQ), and the Control Attitudes Scale-Revised (CAS-R) were used for on-site investigation.Results:Totally 320 patients were included in this study, including 177 males and 143 females, aged (61.64 ± 10.74) years old. The total score of BIPQ was (42.98 ± 10.49) points, the total score of CAS-R was (27.20 ± 5.65) points. The results of multiple linear regression analysis showed that age, resting heart rate, postoperative course, and perceived control were the influencing factors of illness perception ( F = 25.24, P<0.05). Conclusions:The illness perception of atrial fibrillation patients during the blanking period after PVI needs to be improved urgently. Medical staff should pay more attention to patients with old age, fast resting heart rate, short postoperative course, and low perceived control, and take effective measures to reduce negative illness perception and promote postoperative rehabilitation.

Objective:To investigate the differences in the expression of microRNA (miR)-216a and its target gene SerpinB5 at the tissue level, and the effects of miR-216a on the proliferation of different liver cancer cells by regulating the expression of SerpinB5.Methods:Through bioinformatics prediction and selection of miR-216a that regulated SerpinB5. the expressions in liver cancer and normal tissues were detected by real time polymerase chain reaction (PCR). The miR-216a simulacrum and inhibitor, si-Serpinb5 and pcdna3.1-Serpinb5 to HepG2 and MHCC97H (97H) were transfected with liposomes, respectively. Real time PCR and Wester-Blot were used to detect the expression of miR-216a and SerpinB5 before and after transfection, and CCK8 was used to detect the influence of both on the proliferation of liver cancer cells.Results:The expression of miR-216a in human liver cancer tissues was higher than that in adjacent tissues, and the difference was statistically significant ( P < 0.01). The expression of SerpinB5 in human liver cancer tissues was lower than that adjacent tissues, and the difference was statistically significant ( P < 0.01). In HepG2 and 97H, miR-216a inhibitor and SerpinB5 overexpression group showed down-regulated miR-216a expression, which was statistically different from the control group ( P < 0.01). The proliferation of miR-216a inhibitor and pcdna3.1-serpinb5 group was lower than the control group, with statistically significant differences ( P < 0.01). Conclusions:The high expression of SerpinB5 can inhibit the proliferation of liver cancer cells, suggesting that SerpinB5 may have an anti-oncogene effect. MiR-216a may negatively regulate the expression of SerpinB5 and affect the proliferation of HCC cells.

Hypertension and its associated cardiovascular diseases such as stroke and ischemic heart disease result in a high burden of disease and health losses, making it the most burdensome disease in the world and one of the important public health issues in China. Currently Chinese scholars have carried out a large number of studies on the prevalence of hypertension, including regional and national prevalence studies. However, long-term follow-up studies on incidence of hypertension are relatively few and mostly limited to specific ages and regions. This paper summarizes the prevalence, incidence and epidemiological trend of hypertension in Chinese adults. The hypertension prevalence increased from 5.1% in 1959 to 27.5% in 2018, and presents an overall trend of high in the north and low in the south. The hypertension incidence is at a high level (the cumulative incidence was 33.4% after 22 years-follow-up), but there are few researches on the trend of hypertension incidence in huge region.
