Objective:To analyze the latent prevalence of hepatitis B and type 2 diabetes and their correlation through an observational study.Methods:This study used a case-control design. The cases with diabetes were recruited through the diabetes management system and village doctors, while the controls without diabetes were screened from volunteers recruited by village health clinics. Capillary blood samples were collected from the study participants for the measurement of real-time blood glucose level, and venous blood samples were taken from them for the detections of HBV serological markers. Firth logistic regression model was used to fit the relationship between HBsAg positive status and diabetes status.Results:The study included 1 218 diabetes patients, 62 patients with impaired fasting glucose and 491 cases without diabetes. In the cases without diagnosis of diabetes, 11.15% had impaired fasting blood glucose and 4.43% had diabetes. Among those who reported no or unknown diagnosis of hepatitis B, 1.73% were positive for HBsAg, while 18.80% were positive for both HBV core antibody and surface antibody, indicating latent infection of hepatitis B virus. In the non-diabetes group, 0.81% reported hepatitis B history, and in the diabetes group, 2.76% reported hepatitis B history. After adjustment, the HBsAg positive rate was higher in the diabetes group ( OR=2.90, 95% CI: 1.21-6.91). Conclusions:Both diabetes and hepatitis B exhibited a high degree of latent prevalence. The HBsAg positive rate was significantly higher in those with diabetes than in those without diabetes, indicating a potential correlation. These findings highlighted the importance of strengthened screening and management of comorbidities.

OBJECTIVE: To study the effect of silencing LncRNA SNHG7 on hypoxia/reoxygenation (H/R)-induced cardiomyocyte injury and its targeted regulation on miR-181b-5p. METHODS: Rat cardiomyocytes H9c2 were cultured in vitro and randomly divided into control group, H/R group, H/R + si-NC group, H/R + si-SNHG7 group, H/R + si-SNHG7 + anti-miR-NC group and H/R + si-SNHG7 + anti-miR-181b-5p group. The content of lactate dehydrogenase (LDH), malondialedhyde (MDA) and the activity of superoxide dismutase (SOD) were detected. Flow cytometry was carried out to detect the rate of apoptosis. qRT-PCR was used to detect the expression of SNHG7 and miR-181b-5p. Dual luciferase report experiment was used to verify the targeting relationship between SNHG7 and miR-181b-5p. Western blotting was used to detect the expression of Bax and Bcl-2. RESULTS: Compared with the control group, the H/R group showed significantly increased SNHG7 expression in cardiomyocytes, reduced miR-181b-5p expression, higher levels of LDH and MDA, reduced activity of SOD, increased cell apoptosis rate, higher level of Bax protein, and reduced level of Bcl-2 protein (all P< 0.05). Compared with the H/R and H/R + si-NC groups, the H/R + si-SNHG7 group had significantly reduced level of LDH and MDA, increased activity of SOD, reduced apoptosis rate, reduced level of Bax protein, increased level of Bcl-2 protein (all P< 0.05). The dual luciferase report experiment confirmed that SNHG7 could target miR-181b-5p. Interference with the expression of miR-181b-5p could reduce the effect of silencing SNHG7 on H/R-induced cardiomyocyte oxidative stress and apoptosis. CONCLUSION Silencing SNHG7 may inhibit H/R-induced cardiomyocyte oxidative stress and apoptosis by up-regulating the expression of miR-181b-5p, thereby exerting a protective effect on cardiomyocytes.

To obtain a primary overview of gene diversity and expression pattern in Lycoris longituba, 4,992 ESTs (Expressed Sequence Tags) from L. longituba bud were sequenced and 4,687 cleaned ESTs were used for gene expression analysis. Clustered by the PHRAP program, 967 contigs and 1,343 singlets were obtained. Blast search showed that 179 contigs and 227 singlets (totally 1,066 ESTs) had homologues in GenBank and 3,621 ESTs were novel.
