Objective To analyze the epidemiological characteristics of statutory infectious diseases in Yichang City from 2015 to 2023 and evaluate the effectiveness of non-pharmaceutical interventions (NPIs) in infectious disease prevention and control, and to provide a basis for formulating prevention and control strategies. Methods Descriptive epidemiological methods were used to analyze annual incidence rates. SARIMA and SARIMA intervention models were constructed to predict the incidence rates of infectious diseases. Interrupted time series analysis (ITS) was applied to assess the control effectiveness. Results The average annual incidence rate from 2015 to 2023 was 787.47/100 000, with the top five diseases being influenza, hand-foot-and-mouth disease, hepatitis B, tuberculosis, and diarrheal diseases. The average incidence rate from 2015 to 2019 (654.31/100 000) was significantly higher than that from 2020 to 2022 (489.01/100 000) (χ²= 3 499.6, P < 0.05). The total incidence rate in 2023 (2 396.51/100 000) was significantly higher than the average annual incidence rates from 2015-2019 (χ²= 108 186.1, P < 0.05) and 2020-2022 (χ²= 112 869.4, P < 0.05). SARIMA model results indicated that the actual incidence rate from 2020 to 2022 decreased by 73.49% compared to the predicted rate without intervention, with the highest decline observed in respiratory infectious diseases (79.57%). The SARIMA-intervention model showed a 55.48% relative decrease in the total incidence rate for 2023, with the largest reduction in respiratory infectious diseases (63.28%) and a slight increase in intestinal infectious diseases (5.48%). Conclusion NPIs effectively reduce the incidence of statutory infectious diseases in the short term, especially for acute respiratory and intestinal infectious diseases. However, long-term effectiveness faces challenges, necessitating the development of differentiated prevention and control strategies.

Serine protease inhibitor Kazal-type (SPINK) is a skin keratinizing protease inhibitor, which was initially found in animal serum and is widely present in plants, animals, bacteria, and viruses, and they act as key regulators of skin keratinizing proteases and are involved in the regulation of keratinocyte proliferation and inflammation, primarily through the inhibition of deregulated tissue kinin-releasing enzymes (KLKs) in skin response. This process plays a crucial role in alleviating various skin problems caused by hyperkeratinization and inflammation, and can greatly improve the overall condition of the skin. Specifically, the different members of the SPINK family, such as SPINK5, SPINK6, SPINK7, and SPINK9, each have unique biological functions and mechanisms of action. The existence of these members demonstrates the diversity and complexity of skin health and disease. First, SPINK5 mutations are closely associated with the development of various skin diseases, such as Netherton’s syndrome and atopic dermatitis, and SPINK5 is able to inhibit the activation of the STAT3 signaling pathway, thereby effectively preventing the metastasis of melanoma cells, which is important in preventing the invasion and migration of malignant tumors. Secondly, SPINK6 is mainly distributed in the epidermis and contains lysine and glutamate residues, which can act as a substrate for epidermal transglutaminase to maintain the normal structure and function of the skin. In addition, SPINK6 can activate the intracellular ERK1/2 and AKT signaling pathways through the activation of epidermal growth factor receptor and protease receptor-2 (EphA2), which can promote the migration of melanoma cells, and SPINK6 further deepens its role in stimulating the migration of malignant tumor cells by inhibiting the activation of STAT3 signaling pathway. This process further deepens its potential impact in stimulating tumor invasive migration. Furthermore, SPINK7 plays a role in the pathology of some inflammatory skin diseases, and is likely to be an important factor contributing to the exacerbation of skin diseases by promoting aberrant proliferation of keratinocytes and local inflammatory responses. Finally, SPINK9 can induce cell migration and promote skin wound healing by activating purinergic receptor 2 (P2R) to induce phosphorylation of epidermal growth factor and further activating the downstream ERK1/2 signaling pathway. In addition, SPINK9 also plays an antimicrobial role, preventing the interference of some pathogenic microorganisms. Taken as a whole, some members of the SPINK family may be potential targets for the treatment of dermatological disorders by regulating multiple biological processes such as keratinization metabolism and immuno-inflammatory processes in the skin. The development of drugs such as small molecule inhibitors and monoclonal antibodies has great potential for the treatment of dermatologic diseases, and future research on SPINK will help to gain a deeper understanding of the physiopathologic processes of the skin. Through its functions and regulatory mechanisms, the formation and maintenance of the skin barrier and the occurrence and development of inflammatory responses can be better understood, which will provide novel ideas and methods for the prevention and treatment of skin diseases.

Normal tension glaucoma （NTG） is recognized as a distinct subtype of primary open-angle glaucoma， characterized by normal intraocular pressure （IOP<21 mmHg） in conjunction with progressive optic neuropathy， retinal ganglion cell （RGC） apoptosis， and visual field defects. The pathogenesis of NTG is predominantly independent of IOP， with fundamental processes involving genetic and mitochondrial factors， including RGC degeneration， neuroinflammation， mitochondrial dysfunction， and genetic predisposition. This article systematically reviews the IOP-independent and gene-driven mechanisms underlying NTG， with a particular focus on the roles of OPTN， TBK1， FOXC1， and OPA1 in inducing RGC damage through pathways such as mitochondrial dysfunction， glial cell activation， inflammatory signaling， apoptosis， and axonal degeneration. Among these genes， OPTN and TBK1 collectively contribute to the development of NTG by disrupting autophagy-mitochondrial homeostasis， causing defects in axonal transport， and activating neuroinflammatory pathways. FOXC1 is implicated in the progression of RGC degeneration through transcriptional regulation， while mutations in OPA1 lead to mitochondria-dependent RGC apoptosis.Additionally， this article provides a comprehensive review of the epigenetic regulation of METTL23， mitochondrial DNA mutations， the role of Alcadein α in axonal transport， the correlation between genes associated with primary open-angle glaucoma （POAG） and normal-tension glaucoma （NTG）， as well as susceptibility loci identified through genome-wide association studies （GWAS）. In the realm of translational research， recent advancements in therapeutic studies encompass strategies such as targeting OPTN E50K， inhibiting CRMP2 phosphorylation， and employing gene augmentation， gene silencing， and gene editing techniques. The etiology of NTG is complex， predominantly independent of intraocular pressure （IOP）， and arises from the interplay between genetic and environmental factors. This article seeks to promote mechanism-based technological innovation， optimize neuroprotective strategies for NTG， and enhance clinical translation， ultimately aiming to achieve precise treatment and improve visual function outcomes for patients.

Primary open angle glaucoma(POAG)is the most common type of glaucoma, with common causes including variations in trabecular tissue and increased venous pressure. POAG has a certain genetic tendency, and POAG with an autosomal dominant inheritance pattern is mainly caused by single gene mutations. Studies have found that the pathogenesis of POAG may be related to key pathogenic genes(MYOC, OPTN, WDR 36), as well as mitochondrial dysfunction, oxidative stress, and epigenetic regulation. At present, the clinical treatment options for POAG mainly include enhancing trabecular meshwork function, inhibiting aqueous humor production, neuroprotection and regeneration of retinal ganglion cells, and applying gene editing technology, all of which have achieved certain results. However, there is no unified research on the relationship between the occurrence of POAG and genes, as well as treatment plans. The article explores new targets and treatment strategies for POAG gene therapy by analyzing the role of genes in the pathogenesis of POAG, aiming to provide reference for clinical treatment of this disease.

This study investigated the effects and underlying mechanisms of vanillic acid(VA) against cardiac fibrosis(CF) induced by isoproterenol(ISO) in mice. Male C57BL/6J mice were randomly divided into control group, VA group(100 mg·kg~(-1), ig), ISO group(10 mg·kg~(-1), sc), ISO + VA group(10 mg·kg~(-1), sc + 100 mg·kg~(-1), ig), ISO + dynamin-related protein 1(Drp1) inhibitor(Mdivi-1) group(10 mg·kg~(-1), sc + 50 mg·kg~(-1), ip), and ISO + VA + Mdivi-1 group(10 mg·kg~(-1), sc + 100 mg·kg~(-1), ig + 50 mg·kg~(-1), ip). The treatment groups received the corresponding medications once daily for 14 consecutive days. On the day after the last administration, cardiac functions were evaluated, and serum and cardiac tissue samples were collected. These samples were analyzed for serum aspartate aminotransferase(AST), lactate dehydrogenase(LDH), creatine kinase-MB(CK-MB), cardiac troponin I(cTnI), reactive oxygen species(ROS), interleukin(IL)-1β, IL-4, IL-6, IL-10, IL-18, and tumor necrosis factor-α(TNF-α) levels, as well as cardiac tissue catalase(CAT), glutathione(GSH), malondialdehyde(MDA), myeloperoxidase(MPO), superoxide dismutase(SOD), total antioxidant capacity(T-AOC) activities, and cytochrome C levels in mitochondria and cytoplasm. Hematoxylin-eosin, Masson, uranium acetate and lead citrate staining were used to observe morphological and mitochondrial ultrastructural changes in the cardiac tissues, and myocardial injury area and collagen volume fraction were calculated. Flow cytometry was applied to detect the relative content and M1/M2 polarization of cardiac macrophages. The mRNA expression levels of macrophage polarization markers [CD86, CD206, arginase 1(Arg-1), inducible nitric oxide synthase(iNOS)], CF markers [type Ⅰ collagen(Coll Ⅰ), Coll Ⅲ, α-smooth muscle actin(α-SMA)], and cytokines(IL-1β, IL-4, IL-6, IL-10, IL-18, TNF-α) in cardiac tissues were determined by quantitative real-time PCR. Western blot was used to detect the protein expression levels of Coll Ⅰ, Coll Ⅲ, α-SMA, Drp1, p-Drp1, voltage-dependent anion channel(VDAC), hexokinase 1(HK1), NOD-like receptor protein 3(NLRP3), apoptosis-associated speck-like protein(ASC), caspase-1, cleaved-caspase-1, gasdermin D(GSDMD), cleaved N-terminal gasdermin D(GSDMD-N), IL-1β, IL-18, B-cell lymphoma-2(Bcl-2), B-cell lymphoma-xl(Bcl-xl), Bcl-2-associated death promoter(Bad), Bcl-2-associated X protein(Bax), apoptotic protease activating factor-1(Apaf-1), pro-caspase-3, cleaved-caspase-3, pro-caspase-9, cleaved-caspase-9, poly(ADP-ribose) polymerase-1(PARP-1), and cleaved-PARP-1 in cardiac tissues. The results showed that VA significantly improved cardiac function in mice with CF, reduced myocardial injury area and cardiac index, and decreased serum levels of AST, CK-MB, cTnI, LDH, ROS, IL-1β, IL-6, IL-18, and TNF-α. VA also lowered MDA and MPO levels, mRNA expressions of IL-1β, IL-6, IL-18, and TNF-α, and mRNA and protein expressions of Coll Ⅰ, Coll Ⅲ, and α-SMA in cardiac tissues, and increased serum levels of IL-4 and IL-10, cardiac tissue levels of CAT, GSH, SOD, and T-AOC, and mRNA expressions of IL-4 and IL-10. Additionally, VA ameliorated cardiac pathological damage, inhibited myocardial cell apoptosis, inflammatory infiltration, and collagen fiber deposition, reduced collagen volume fraction, and alleviated mitochondrial damage. VA decreased the ratio of F4/80~+CD86~+ M1 cells and the mRNA expressions of CD86 and iNOS in cardiac tissue, and increased the ratio of F4/80~+CD206~+ M2 cells and the mRNA expressions of CD206 and Arg-1. VA also reduced protein expressions of p-Drp1, VDAC, NLRP3, ASC, caspase-1, cleaved-caspase-1, GSDMD, GSDMD-N, IL-1β, IL-18, Bad, Bax, Apaf-1, cleaved-caspase-3, cleaved-caspase-9, cleaved-PARP-1, and cytoplasmic cytochrome C, and increased the expressions of HK1, Bcl-2, Bcl-xl, pro-caspase-3, pro-caspase-9 proteins, as well as the Bcl-2/Bax and Bcl-xl/Bad ratios and mitochondrial cytochrome C content. These results indicate that VA has a significant ameliorative effect on ISO-induced CF in mice, alleviates ISO-induced oxidative damage and inflammatory response, and its mechanism may be closely related to the inhibition of Drp1/HK1/NLRP3 and mitochondrial apoptosis signaling pathways, suppression of myocardial cell inflammatory infiltration and collagen fiber deposition, reduction of collagen volume fraction and CollⅠ, Coll Ⅲ, and α-SMA expressions, thus mitigating CF.

Objective:Utilizing the principles of mechanical vibrations dissections and low-temperature coagulation of harmonic scalpel, and combining the magnifying effect of 3D thoracoscopy and the advantage of low trauma, we used harmonic scalpel to harvest the left internal mammary artery (LIMA) under thoracoscopy, and explored the feasibility and early effect of harmonic scalpel in minimally invasive coronary artery bypass grafting (MICABG).Methods:A total of 488 patients who underwent MICABG from July 2021 to December 2023 in Dong E Hospital were collected. Among them, 347 patients was harvested using harmonic scalpel under thoracoscopy. Following anastomosis, the blood flow and pulsatility index (PI) from the graft to the target vessel were determined using a transit time flow meter (MiraQ, Medistim, Norway), and patency was checked. Data from 347 patients were analyzed.Results:All 347 patients were performed under non-extracorporeal circulation and successful graft patency was achieved in all patients. Analysis of 79 patients revealed a median time to LIMA acquisition of 32 min and a median length of acquisition of 15 cm. No graft-related events or complications occurred in any of the patients, and 2 patients died postoperatively. During a median follow-up of 12.1 months, only one patient experienced graft occlusion necessitating intervention.Conclusion:The utilization of harmonic scalpel for LIMA harvesting in MICABG is feasible and yields stable early results.

[Objective] To review the clinical information, imaging features, pathological manifestations and prognosis of low-grade oncocytic tumor (LOT), so as to improve the clinical understanding of the disease. [Methods] The imaging, clinicopathological and postoperative follow-up data of 3 LOT cases treated in Peking University Third Hospital during Feb.2020 and Sep.2022 were retrospectively collected. [Results] All patients were male, aged 51—70 years.All tumors were single, with the maximum diameter of 14—21 mm. None of the patients had any specific clinical manifestations.The mass showed a circular isodense shadow on CT.All patients underwent nephron-sparing tumor resection.Postoperative pathology showed that the incision surface of the tumors was brownish-yellow or brown, and the tumors were solid or partially cystic.HE staining showed that the cells were uniformly eosinophilic; the nucleus was round or oval, with slight local perinuclear halo.Immunohistochemistry showed positive CK7 but negative CD117.Genetic testing in case 2 showed 1 potentially clinically significant somatic mutation TSC2.During the follow-up of 12-23 months, no recurrence occurred. [Conclusion] There were no obvious clinical symptoms and imaging features of LOT, which morphologically showed heterozygous or borderline characteristics with renal eosinophilia and renal chromophobe cell carcinoma, and the biological behavior was indolent.Nephron-sparing tumor resection promised good prognosis.

Objective To understand the timeliness of antiretroviral therapy (ART) in newly reported HIV/AIDS cases in Yichang from 2016 to 2022 and its influencing factors, and to provide a scientific basis for improving the timeliness of ART in Yichang City. Methods HIV/AIDS cases data from January 1, 2016 to December 31, 2022 were collected, and chi-square tests and logistic regression were used to analyze the factors influencing the timeliness of ART. Results A total of 1 126 HIV/AIDS cases were collected, with local reported cases accounting for 83.13%. The male to female ratio was 5.15:1. The median age was 42 years old (28-53 years old). 41.03% of the cases were unmarried. 38.99% of cases had a first-time CD4+T lymphocytes (CD4 cells) count < 200 cells/µL. Cases with timely first CD4 cell test accounted for 67.85%. The overall timely rate of ART from 2016 to 2022 was 57.19%, with a median time from diagnosis to initiation of ART of 20 days. There was no statistically significant difference in the trend of ART timely rate from 2016 to 2022 (P=0.251). Cases with timely first CD4 cell test were more likely to initiate ART in time (OR=3.831, 95% CI:2.454-5.981), while cases reported from other areas (OR=0.497, 95% CI:0.345-0.716) and cases with higher first CD4 cell count levels (OR_≥500=0.473, 95% CI:0.312-0.718) were less likely to initiate ART in time. Conclusion The timely rate of antiviral treatment in Yichang City needs to be further improved. High attention should be paid to cases reported from other places, cases with delayed CD4 cell testing, and cases with high CD4 cell count levels. Treatment mobilization and referral should be done well, and early detection services should be provided in time.

Objective To investigate the characteristics and influencing factors of mental health status of permanent residents in Yichang, Hubei Province. Methods A total of 9 576 permanent residents aged 18 years and older from Yichang City were selected by a multistage random sampling method between June and October 2022. The PHQ-9 was used to assess the residents’ depressive symptoms, the GAD-7 was used to assess their anxiety symptoms, the ISI was used to assess their insomnia status, and the PCL-5 was used to assess their stress status. The influence factors of depression and anxiety were analyzed using χ2 test and logistic regression. Results A total of 9 122 valid questionnaires were completed. The detection rate of depression, anxiety, insomnia, and stress symptoms were 29.98%, 19.03%, 11.97% and 1.58%, respectively. Gender, education level, monthly family income, self-rated health status, mental health literacy level, total GAD-7 score, total ISI score, and total PCL-5 score were the main factors that caused residents' anxiety symptoms, while gender, education level, self-rated health status, total PHQ-9 score, total ISI score, and total PCL-5 score were the main factors that caused residents' anxiety symptoms. Conclusion The prevalence of depression and anxiety is high among the permanent residents in Yichang, while the situation of insomnia and stress is relatively good. Measures such as improving the level of mental health literacy can be taken to improve mental health level of residents in Yichang.
