Abstract: Objective To analyze risk factors associated with the development of type 2 diabetes mellitus (T2DM) in patients with hepatitis B virus (HBV) infection. Methods Clinical data were collected from HBV-infected patients treated at the Zhoukou City Infectious Disease Hospital (Zhoukou City Tuberculosis Prevention and Control Institute)between January 2024 and May 2025. A total of 95 patients were included in the study, Patients were grouped based on the presence or absence of T2DM following HBV infection. Patients with T2DM were included in the T2DM group (n=21), while those without T2DM were included in the control group (n=74). Baseline characteristics and laboratory test data were compared between the two groups, and logistic regression analysis was performed to identify factors associated with the development of T2DM in HBV-infected patients. Results The age, body mass index (BMI), and triglycerides (TG) in the intervention group were higher than those in the control group (P < 0.05); The proportion of cases with age ≥45 years, obese BMI, HBV infection duration ≥6 months, TG ≥1.7 mmol/L, smoking, hepatitis B surface antigen (HBsAg) positivity, and a FIB-4 score ≥2.67 was higher than that in the control group (P < 0.05). Age ≥ 45 years [OR = 21.599 (95% CI: 2.875–162.262)], BMI (obesity) [OR = 16.729 (95% CI: 1.443–193.981)], duration of HBV infection ≥ 6 months [OR = 6.199 (95% CI: 1.101–34.904)], smoking [OR=9.429 (95% CI: 1.344–66.141)], and TG ≥ 1.7 mmol/L [OR=71.834 (95% CI: 7.060–730.897)] were risk factors for T2DM in patients with HBV infection (P < 0.05). Conclusion The development of T2DM in patients with HBV infection is influenced by a combination of demographic factors (age and BMI), clinical course (duration of HBV infection), comorbid dyslipidemia, and lifestyle factors (smoking).

慢性乙型肝炎（CHB）是我国常见的传染病,随着乙型肝炎病毒（HBV）在体内持续活跃复制可进展为肝硬化甚至肝癌,严重威胁患者健康与生命,而高病毒载量CHB患者不仅进展为肝硬化、肝癌的风险和发生母婴垂直传播的风险增加,还存在抗病毒治疗病毒学应答率偏低等特点,目前对高病毒载量CHB患者的管理已引起国内外学者的关注,但尚缺乏系统的研究与阐述。本文将针对上述问题结合国内外相关文献进行综述,期望今后本领域学者对高病毒载量CHB这类特殊患者能有更深入的研究。

Chronic hepatitis B（CHB）is a common infectious disease in China．With the continuous active replication of hepatitis B virus（HBV）in the body,cirrhosis and even liver cancer can progress,seriously threatening the health and life of patients．However,CHB patients with high viral load not only have an increased risk of cirrhosis and liver cancer,mother-to-child vertical transmission,but also with a lower rate of virological response to antiviral therapy．At present,the management of CHB patients with high viral load has attracted the attention of scholars at home and abroad,but there is still a lack of systematic research and elaboration．This paper will focus on the above problems combined with relevant domestic and foreign literature review,hoping that scholars in this field can have more in-depth research on special patients with high viral load CHB in the future．

Objective In order to explore the role of long non-coding RNA SNHG12 in hepatitis B virus X protein (HBx) induced hepatocarcinogenesis. Methods The liver precursor cells 14-19, EGFP-14-19 and HBx-EGFP-14-19 constructed by the research group was injected into the body through the hepatic portal vein of KM mice; qRT-PCR and Western blot were used to detect the mRNA and protein expression of HBx, SNHG12 and downstream regulatory genes in liver tissues of 30 d, 90 d, 180 d and 360 d mice and cell models. Si-SNHG12 was used to interfere with SNHG12 expression in vitro, the mRNA and protein expression of SNHG12 and downstream genes were detected, and its effect on phenotype in vitro was observed by CCK-8, flow cytometry, scratch test and transwell test. HE staining was used to observe the liver sections of mice. Results qRT-PCR showed that SNHG12, Notch1 and Hes1 were up-regulated in HBx overexpression cells and mouse liver tissue at each time point (F=48.808,P<0.000 1;F=13.322,P<0.000 1); the results of Western blot showed that in HBx over-expressing cells and animal models, the expression of SNHG12 was increased induced by HBx, resulting in the activation of Notch1 signal pathway, the down regulation of pro-apoptotic factor Bax, anti-apoptotic factor Bcl-2, and the up-regulation of cell cycle factors CDK2, cyclin E. After inhibiting the expression of SNHG12, the results of qRT-PCR and Western blot showed that SNHG12 (t=22.746,P<0.000 1) and the above genes were inhibited; CCK-8 experiment showed that cell proliferation was significantly inhibited, flow cytometry showed that cell apoptosis increased, scratch experiment and transwell experiment showed that cell migration and invasion decreased. Conclusions HBx induced Notch1 expression by up regulating SNHG12, resulting in abnormal cell proliferation, cycle and apoptosis, so as to promote the occurrence of liver cancer.

目的 探讨肺部超声(LUS)在高龄(≥75 岁)感染新型冠状病毒肺炎(COVID-19)患者中的应用及后续对病程的监测及诊断价值。方法 回顾性分析2022年11月1日—2023年1月15日本院内科收治的25例COVID-19高龄患者进行病例归纳总结,除临床资料外,动态监测肺部超声检查情况,并与肺CT结果对比,观察检查结果,以及对病程转归的预判及影响。结果 LUS检查提示患者出现不同程度肺间质损伤,包括离散型B线(间质渗出)或融合型B线(渗入肺泡)以及肺实变(肺泡萎陷)。随着病情好转,LUS可见肺实变范围缩小,B线逐步稀疏到消散,A 线出现。结论 LUS与同期胸部CT结果一致性良好。LUS检查安全简便,重复性好,可实时动态监测,即可作为初筛手段,亦可运用于特殊人群,协助临床治疗决策。

Objective To explore the application and follow-up monitoring and diagnostic value of lung ultrasound (LUS) in elderly patients(≥75y) with novel coronavirus pneumonia (COVID-19). Methods Data of 25 COVID-19 elderly patients admitted to the Department of Internal Medicine from November 1, 2022 to January 15, 2023 were retrospectively analyzed and summarized. In addition to clinical data, dynamic monitoring of LUS was performed, and the results were compared with lung CT results. The examination results, as well as the prediction and impact on the course of disease were observed. Results LUS imaging indicated that patients had different degrees of interstitial lung injury, including discrete type B line (interstitial exudation) or fusion type B line (alveolar infiltration) and lung consolidation (alveolar collapse). With the improvement of the disease, the range of lung consolidation seen in LUS was reduced, the B-line was gradually sparse to dissipate, and the A-line appeared. Conclusions The results of LUS and chest CT in the same period are consistent. LUS examination is safe, simple, reproducible, and can be monitored dynamically in real time. It can be used as a primary screening method, and also be used in special patients to assist clinical treatment decision-making.
