Retinitis pigmentosa (RP) is the most common hereditary blinding eye disease in clinical practice, with the pathogenesis remaining unclear. Patients experience progressive apoptosis of retinal photoreceptor cells, accompanied by degeneration of retinal pigment epithelium (RPE) cells. Current Western medical treatments mainly focus on gene therapy and stem cell transplantation, showing limited efficacy. In contrast, clinical observations have confirmed the therapeutic effects of traditional Chinese medicine (TCM) treatments. Establishing an RP animal model that aligns with the diagnostic features of both TCM and Western medicine could help combine the strengths of both approaches, thereby broadening the treatment options for RP. This study categorizes and summarizes the existing RP animal models in terms of classification, types, inheritance patterns, and alignment with clinical manifestations. It is found that current RP models are primarily derived from natural animal models such as RD mice and RCS rats, transgenic animal models like RPE-65 knockout mice and rhodopsin gene knockout mice, and chemically induced models such as those created by monochromatic light exposure or N-ethyl-N-nitrosourea (ENU) administration. These three categories of models focus more on detecting RP-related histopathological, molecular biological, and cellular immunological indicators, but offer limited observation of the overall characteristics of the disease and lack insight into syndrome differentiation. Although RP is a congenital genetic disease, its progression is influenced by acquired factors such as environment, constitution, emotions, and care. Current models do not fully capture the characteristics of this disease. Therefore, establishing an RP animal model based on the diagnostic features of both TCM and Western medicine will have significant implications for future experimental and clinical research.

Objective:
To analyze the epidemiological characteristics of pulmonary tuberculosis (PTB) in Jinhua City, Zhejiang Province from 2015 to 2024, so as to provide the evidence for optimizing tuberculosis control strategies.
Methods:
Data of PTB cases in Jinhua City from 2015 to 2024 were collected through the China Disease Prevention and Control Information System. Descriptive epidemiological methods were used to analyze the population, temporal and spatial distribution characteristics of PTB cases. Seasonal index was used to analyze temporal distribution characteristics. The average annual percent change (AAPC) was used to analyze the trends in reported incidence and etiological positivity rate of PTB from 2015 to 2024.
Results:
A total of 34 750 PTB cases were reported in Jinhua City from 2015 to 2024, with an average annual reported incidence of 56.35/105. There were 20 054 cases with positive etiological test results, with a positive rate of 57.71%. The reported incidence of PTB showed an overall declining trend (AAPC=-5.814%, P<0.05), while the etiological positivity rate demonstrated an overall upward trend (AAPC=6.687%, P<0.05). The average annual reported incidence of PTB was 71.29/105 in males, higher than 39.98/105 in females (P<0.05). The reported incidence in both males and females showed a downward trend (AAPC=-5.909%, -6.803%, both P<0.05). The population aged ≥60 years had a higher proportion and reported incidence, which were 40.15% and 134.05/105, respectively. The reported incidence showed downward trends in the groups aged 0-<20 years, 20-<40 years, 40-<60 years, and ≥60 years (AAPC=-11.191%, -10.849%, -6.343%, and -4.006%, all P<0.05). Farmers were the predominant occupation, with 21 584 cases, accounting for 62.11%. PTB was highly prevalent from March to September, with a higher seasonal index in May (116.37%). Lanxi City, Pujiang County and Yiwu City had higher reported incidence, which were 77.85/105, 65.89/105 and 60.77/105, respectively. Except for Pan'an County where the trend in reported incidence was not statistically significant (P>0.05), the reported incidence in other regions showed downward trends, with AAPC values ranging from -9.039% to -1.964% (all P<0.05).
Conclusions
From 2015 to 2024, the reported incidence of PTB in Jinhua City showed an overall declining trend, while the pathogen positivity rate showed an upward trend. PTB was highly prevalent in spring and summer. Males, the elderly and farmers were the key target population for prevention and control. Lanxi City, Pujiang County and Yiwu City were high-incidence areas.

This paper summarizes Professor Gao Jiansheng's clinical experience in treating herpes simplex keratitis (HSK) based on the theory of hidden pathogens. It is believed that the core pathogenesis of HSK involves deficiency of vital qi and the internal presence of pathogenic factors. In the early stage, the pathogenesis is characterized by lung and spleen qi deficiency and invasion of external pathogens. In the middle stage, pathogenesis worsens due to latent pathogens damaging the vital qi and spleen deficiency with dampness. In the late stage, kidney yang deficiency and lingering pathogenic toxins are the root cause of recurrent attacks. In clinical practice, it is recommended to strengthen and protect the vital qi. In the early stage, the Modified Yupingfeng Powder (玉屏风散) is used. In the middle stage, the Modified Linggui Zhugan Decoction (苓桂术甘汤) is used. In the late stage, a self-formulated Modified Bushen Tuodu Fomulation (补肾托毒方) is applied. Additionally, herbs of tonifying qi and strengthening the exterior are used throughout the treatment to reduce recurrence.

Benign essential blepharospasm(BEB)is a neurological disorder characterized by involuntary contractions of periocular muscles, which can lead to functional blindness and significantly impair patients' quality of life. This article systematically reviews the epidemiology, clinical manifestations, pathogenesis, and therapeutic advances in BEB. Epidemiological data indicate that the global prevalence of BEB is approximately 1 in 200000, with a predilection for individuals over 50 years of age and a significantly higher incidence in female than in male. The exact pathogenesis of BEB remains incompletely understood, though current evidence suggests close associations with neurotransmitter dysfunction, reduced cortical inhibition, and genetic susceptibility. Therapeutic strategies primarily focus on symptomatic management. Botulinum toxin type A(BTX-A)injection remains the first-line treatment but requires repeated administrations due to transient efficacy. Other treatments, including oral drugs, surgery, and repetitive transcranial magnetic stimulation, also have major limitations. By synthesizing recent research progress from domestic and international studies, this review aims to provide novel insights for the clinical management of BEB, ultimately improving patient outcomes.

Hypoxemia is a common pathological state characterized by low oxygen saturation in the blood. This condition compromises mucosal barrier integrity particularly in the gut and oral cavity. However, the mechanisms underlying this association remain unclear. This study used periodontitis as a model to investigate the role of platelet activation in oral mucosal immunopathology under hypoxic conditions. Hypoxia upregulated methyltransferase-like protein 4 (METTL4) expression in platelets, resulting in N6-methyladenine modification of mitochondrial DNA (mtDNA). This modification impaired mitochondrial transcriptional factor A-dependent cytosolic mtDNA degradation, leading to cytosolic mtDNA accumulation. Excess cytosolic mt-DNA aberrantly activated the cGAS-STING pathway in platelets. This resulted in excessive platelet activation and neutrophil extracellular trap formation that ultimately exacerbated periodontitis. Targeting platelet METTL4 and its downstream pathways offers a potential strategy for managing oral mucosa immunopathology. Further research is needed to examine its broader implications for mucosal inflammation under hypoxic conditions.

Objective:To analyze the factors affecting quality of life in patients with early esophageal cancer after endoscopic submucosal dissection (ESD) .Methods:Convenience sampling was used to select 162 early esophageal cancer patients with ESD in Cangzhou Central Hospital from August 2021 to July 2023 who had an on-time follow-up six months as study subjects. General Information Questionnaire and Quality of Life Instruments for Cancer Patients-Esophageal Cancer (QLICP-ES) were used to investigate the patients. Factors affecting the quality of life of patients after ESD for early esophageal cancer were analyzed using univariate analysis and multiple linear regression analysis.Results:Univariate analysis showed statistically significant differences in QLICP-ES scores among patients with different gender, age, marital status, annual income, medical payment method, concomitant diseases, degree of infiltration, vascular invasion, surgical complications, and positive margins ( P<0.05). Multiple linear regression analysis showed that age, marital status, concomitant diseases, vascular invasion, surgical complications, and positive margins were the factors influencing the QLICP-ES scores of patients with ESD for early esophageal cancer, and the differences were statistically significant ( P<0.05) . Conclusions:Quality of life at six months after ESD in patients with early esophageal cancer is at an intermediate to high level. Patients of advanced age, unmarried/divorced/widowed, concomitant diseases, vascular invasion, surgical complications and positive margins have low QLICP-ES scores after ESD for early esophageal cancer. It is recommended that clinical attention be focused on these factors and that targeted nursing measures be taken when necessary.

Abstract
Background and aims
Hepatic ischemia-reperfusion injury (HIRI) is a major contributor to liver dysfunction and failure, particularly in the context of liver transplantation. Its pathogenesis is primarily driven by ferroptosis, oxidative stress, and mitochondrial dysfunction. Given the interplay among these mechanisms through redox imbalance and disrupted energy metabolism, nicotinic acid (NA)—recognized for its antioxidative and metabolic regulatory properties—emerges as a promising therapeutic candidate. This study aims to investigate the protective effects of NA on HIRI and elucidate its underlying mechanisms.
Methods
An HIRI model in mice and a hypoxia/reoxygenation (H/R) model in primary hepatocytes were established to evaluate the effects of NA treatment on oxidative stress. NA was administered prior to model induction. N-acetylcysteine (NAC) was used as a comparator. Comprehensive assessments of ferroptosis, oxidative stress, mitophagy, and mitochondrial biogenesis markers were conducted using Western blotting, immunohistochemistry, immunofluorescence, and biochemical assays.
Results
NA pretreatment reduced serum alanine aminotransferase, aspartate aminotransferase, and lactate dehydrogenase (LDH) levels, suppressed inflammation by decreasing neutrophil infiltration and macrophage activation, and mitigated oxidative stress by lowering reactive oxygen species (ROS) and malondialdehyde (MDA) levels. It enhanced antioxidant defenses, inhibited ferroptosis, and improved mitochondrial health through increased mitophagy, mitochondrial biogenesis, and mitochondrial permeability transition pore (mPTP) stabilization, leading to enhanced ATP production and mitochondrial function in HIRI.
Conclusions
NA improves mitochondrial function by promoting mitophagy and mitochondrial biogenesis, which reduces ferroptosis and oxidative stress, thereby alleviating HIRI.

Objective:
To learn the status and influencing factors of development among infants at ages of 0 to 36 months in Xiaoshan District, Hangzhou City, so as to provide the reference for promoting healthy development of infants.
Methods:
Infants at ages of 0-36 months who underwent physical examination in Child Health Clinic of Xiaoshan District Community Health Service Center were selected in 2022. General data of infants and their mothers were collected through questionnaires, and the development status of infants was screened by Age and Stages Questionnaire (third edition). Factors affecting the development status were identified using a multivariable logistic regression model.
Results:
A total of 2 519 infants were investigated, including 1 339 males (53.16%) and 1 180 females (46.84%). There were 608 infants with abnormal development of at least one functional area of communication (CM), gross motor (GM), fine motor (FM), problems solving (CG) and personal-social (PS). The abnormal rate was 24.14%, and the abnormal rates of the above functional areas were 9.77%, 6.59%, 7.98%, 6.39% and 9.33%, respectively. Multivariable logistic regression analysis showed that gender (male, OR=1.563, 95%CI: 1.191-2.052), mother's childbearing age (≥35 years, OR=1.411, 95%CI: 1.001-1.988), mother's educational level (lower than junior college, OR=1.460, 95%CI: 1.116-1.912) were factors affecting abnormal development of CM; preterm birth (OR=2.323, 95%CI: 1.315-4.103) was factors affecting abnormal development of GM; gender (male, OR=1.654, 95%CI: 1.225-2.232) was factors affecting abnormal development of FM; gender (male, OR=1.511, 95%CI: 1.086-2.102) and mode of delivery (cesarean section, OR=1.460, 95%CI: 1.060-2.010) were factors affecting abnormal development of CG; gender (male, OR=1.340, 95%CI: 1.019-1.763) and birth weight (low birth weight, OR=1.985, 95%CI: 1.149-3.432) were factors affecting abnormal development of PS.
Conclusions
The rate of abnormal development among infants at ages of 0 to 36 months in Xiaoshan District is 24.14%. Gender, preterm birth, mode of delivery, birth weight, mother's childbearing age and mother's educational level could affect the development status of infants.
