OBJECTIVE To analyze the clinical characteristics of Stevens-Johnson syndrome （SJS） and toxic epidermal necrolysis （TEN） induced by tislelizumab， providing evidence for clinical medication safety. METHODS Case reports of tislelizumab-related SJS/TEN were retrieved from CNKI， VIP， Wanfang Data， PubMed， ScienceDirect， and Embase. Descriptive analysis was performed. RESULTS Seventeen cases from 17 publications were included （SJS 4 cases， TEN 13 cases）. Among them， there were 10 males and 7 females. Twelve patients were aged between 70 and 79 years. The predominant tumor type was lung cancer （10 cases）. Thirteen patients received combination therapy with chemotherapeutic drugs. The median onset time of SJS/ TEN was 26 （4， 104） days. Nine patients developed SJS/TEN after the first administration of the drug. Sixteen patients exhibited prodromal rash symptoms， primarily characterized by severe skin damage such as skin detachment， accompanied by mucosal injury. Sixteen patients improved after symptomatic treatment， while one patient died. CONCLUSIONS Tislelizumab-associated SJS/TEN risk is higher in elderly patients， males， those with lung cancer and those receiving combination chemotherapy. Mucosal lesions and atypical rashes may indicate the early onset of SJS/TEN. During clinical use， pharmaceutical care can be carried out through measures such as identifying high-risk populations， closely monitoring skin symptoms from the first administration to the fifth treatment cycle， and enhancing patient education. When relevant symptoms occur， the medication should be promptly discontinued and symptomatic treatment should be administered to ensure the patient’s medication safety.

This paper aims to contribute to guaranteeing the stable development and enhancing the understanding of ecological agriculture of Chinese materia medica so that the national strategy and industrial demand can be better served. It first introduces current traditional Chinese medicine(TCM)policy and industrial development status from five aspects, including policy guarantee, theoretical support, technological innovation, standardization system, and brand influence. Then, the paper analyzes the development dilemma of TCM agriculture in production and quality increase and ecological environment protection. It also proposes the development goals of ecological agriculture of Chinese materia medica that meet the current industrial development demand, which are reducing chemical fertilizers, pesticides, and carbon emissions, improving quality, increasing efficiency, and protecting ecological environment. In addition, the new development goals are interpreted through case studies. Finally, this paper proposes four development strategies for ecological agriculture of Chinese materia medica: conducting research on the pattern and spatial and temporal variations of nationwide TCM production areas; studying the internal and external ecological memories of medicinal plant growth from the perspectives of genetic variations and environmental adaptation variations and elucidating their contributions to the formation of quality; carrying out selection and breeding of stress-resistant varieties for ecological agriculture of Chinese materia medica, the optimization of key technologies for soil improvement and restoration and green prevention and control against diseases and pests, and the improvement of quality; carrying out research on the quality assurance and value realization of ecological products made from TCM. This research can provide guidance for policy formulation, theoretical development of the discipline, and the enhancement of industrial technology for ecological agriculture of Chinese materia medica.

OBJECTIVE: To examine the effectiveness of Chinese medicine (CM) Lianhua Qingwen Granule (LHQW) and Jingyin Gubiao Prescription (JYGB) in asymptomatic or mild patients with Omicron infection in the shelter hospital. METHODS: This single-center retrospective cohort study was conducted in the largest shelter hospital in Shanghai, China, from April 10, 2022 to May 30, 2022. A total of 56,244 asymptomatic and mild Omicron cases were included and divided into 4 groups, i.e., non-administration group (23,702 cases), LHQW group (11,576 cases), JYGB group (12,112 cases), and dual combination of LHQW and JYGB group (8,854 cases). The length of stay (LOS) in the hospital was used to assess the effectiveness of LHQW and JYGB treatment on Omicron infection. RESULTS: Patients aged 41-60 years, with nadir threshold cycle (C_T) value of N gene <25, or those fully vaccinated preferred to receive CM therapy. Before or after propensity score matching (PSM), the multiple linear regression showed that LHQW and JYGB treatment were independent influence factors of LOS (both P<0.001). After PSM, there were significant differences in LOS between the LHQW/JYGB combination and the other groups (P<0.01). The results of factorial design ANOVA proved that the LHQW/JYGB combination therapy synergistically shortened LOS (P=0.032). CONCLUSIONS Patients with a nadir C_T value <25 were more likely to accept CM. The LHQW/JYGB combination therapy could shorten the LOS of Omicron-infected individuals in an isolated environment.

Streptococcus suis is an important zoonotic pathogen.Two outbreaks of large-scale human infections with S.suis have occurred in China,thereby posing a serious public health risk and changing the view that this pathogen causes only sporadic cases in humans.Deeper understanding of the pathogenesis of Streptococcus suis is urgently needed.During the infection process,S.suis sur-vival and virulence in the host is facilitated by circumvention of the immune defense through various virulence factors.The bacterium's pathogenicity is closely associated with the virulence factors it carries.Herein,we review recent progress in the study of virulence fac-tors of S.suis related to overcoming the host intrinsic immune defense,to provide a theoretical basis for the prevention of porcine strep-tococcal diseases and the development of vaccines.

Objective:To investigate the expression and methylation status of the SALL4 gene in placental tissues of fetal growth restriction (FGR) and its effects on trophoblast cell proliferation, migration, and invasion. Methods:Placental tissues were collected from 20 full-term FGR patients and 20 healthy term controls who underwent regular prenatal examination and cesarean section at the Third Affiliated Hospital, Zhengzhou University between July 2023 and February 2024. SALL4 mRNA and protein expression were analyzed by quantitative real-time polymerase chain reaction (qRT-PCR) and Western blot. Methylation specific polymerase china reaction (MSP) assessed promoter methylation levels. HTR8/SVneo cells were transfected with SALL4-targeting small interfering RNA (si-SALL4) or negative control small interfering RNA (si-NC). HTR8/SVneo cells were treated with the demethylating agent 5-aza-2′-deoxycytidine (5-Aza-dC) to inhibit gene methylation (5-Aza-dC group) or with 10% RPMI-1640 medium as a vehicle control. Transfection efficiency (for siRNA) and the efficacy of 5-Aza-dC-induced demethylation were assessed by qRT-PCR and Western blot. The functional effects of SALL4 knockdown and methylation inhibition on trophoblast cells were evaluated using proliferation assays, scratch wound healing assays, and Transwell invasion assays. Statistical analyses included independent t-tests and Chi-square test. Results:(1) Human tissues: FGR placentas showed lower SALL4 mRNA (0.802±0.194 vs. 1.015±0.186, t=3.55) and protein expression (0.445±0.114 vs. 0.701±0.113, t=3.19), alongside higher methylation rates of SALL4 [80% (16/20) vs. 15% (3/20), χ2=14.44] compared to controls (all P<0.05). (2) In vitro: si-SALL4 transfection reduced HTR8/SVneo proliferation (OD450 at 48 h: 0.653±0.021 vs. 0.827±0.040, t=6.60), migration [healing rate at 48 h: (24.317±2.637)% vs. (49.327±1.961)%, t=13.18], and invasion [counted invaded cells: (133.000±6.557) vs. (272.667±18.009) cells, t=12.62] versus si-NC (all P<0.05). Conversely, 5-Aza-dC treatment increased HTR8/SVneo proliferation (0.917±0.042 vs. 0.783±0.031, t=－4.47), migration [(71.097±3.354)% vs. (51.632±2.877)%, t=－7.63], and invasion [(384.000±12.166) vs. (202.833±7.095) cells, t=－13.69] versus vehicle control (all P<0.05). Conclusions:Hypermethylation of the SALL4 promoter in FGR placentas suppresses its expression, impairing trophoblast cell function. Demethylation restores SALL4 expression and enhances cellular proliferation, migration, and invasion, involving in the occurrence and development of FGR disease.

Objective To investigate whether successful percutaneous coronary intervention(PCI)could improve symptoms and quality of life(QOL)in left main disease and/or 3-vessel disease patients with diabetes.Methods Patients with left main disease and/or 3-vessel disease who underwent PCI in the First Affiliated Hospital of Air Force Medical University from April 2018 to May 2021 were consecutively enrolled and subdivided into 2 groups:diabetes and no diabetes.Detailed baseline characteristics,symptoms,including dyspnea and angina,assessed with the Rose dyspnea scale(RDS),Seattle angina questionnaire(SAQ),the European quality of life-5 dimensions(EQ-5D)and 12-item short-form health survey(SF-12)questionnaire respectively,procedural details,and 1 month and 1 year follow-up data were collected.Results Among 440 left main disease and/or 3-vessel disease patients,disease was present in 176(40.00％),who had more hypertension,peripheral artery disease,and LCX lesion(all P＜0.05).The incidence of major adverse cardiovascular events(MACE)and all-cause mortality were similar between the two groups(both P＞0.05)at 1 month follow-up,while all-cause mortality in diabetes patients was significantly higher than those without diabetes at 1 year follow-up(P=0.013).Low left ventricular ejection fraction was an independent risk factor for MACE and all-cause mortality at 1 month and 1 year follow-up after successful revascularization(all P＜0.05).Most importantly,symptoms,including dyspnea and angina,and QOL were markedly improved regardless of diabetes both at 1 month and 1 year follow-up(all P＜0.05).Diabetes patients showed improved dyspnea and QOL at similar degree to the non-diabetes patients(all P＞0.05)and a more significantly relieved angina(P=0.013).Additionally,the number of chronic total occlusion(CTO)per patient was identified as an independent risk factor of dyspnea(OR 0.723,95％CI 0.525～0.997,P=0.048)and angina relief(OR 0.686,95％CI 0.473～0.995,P=0.047),and the contrast volume(OR 0.995,95％CI 0.992～0.999,P=0.008)as an independent risk factor of QOL improvement in diabetic patients.Conclusions Successful PCI is beneficial for relieving symptoms and improving quality of life in patients with diabetes who have left main disease and/or 3-vessel disease.
