This article presents a case study of a patient who visited the Geriatric Department of Peking Union Medical College Hospital due to "palpitations, shortness of breath for more than 2 years, limb weakness for 6 months, edema, and nocturnal dyspnea for 2 months". The patient exhibited decreased muscle strength in the limbs and involvement of swallowing and respiratory muscles, alongside complications of heart failure and various arrhythmias which were predominantly atrial. Laboratory tests revealed the presence of multiple autoantibodies and notably anti-mitochondrial antibodies. Following a comprehensive multidisciplinary evaluation, the patient was diagnosed with anti-mitochondrial antibody-associated inflammatory myopathy. Treatment involved a combination of glucocorticoids and immunosuppressants, along with resistance exercises for muscle strength and rehabilitation training for lung function, resulting in significant improvement of clinical symptoms. The case underscores the importance of collaborative multidisciplinary approaches in diagnosing and treating rare diseases in elderly patients, where careful consideration of clinical manifestations and subtle abnormal clinical data can lead to effective interventions.

ObjectiveTo investigate the status and dietary intake risk of pesticide residues in fruits and vegetables sold in Wenzhou, Zhejiang Province from 2020 to 2023, so as to provide a scientific basis for the regulation and management of pesticide in the future. MethodsIn accordance with the requirements and methods specified in the “National Food Contamination and Hazardous Factor Risk Monitoring Work Manual” and the current corresponding national food inspection standards for various foods, a total of 807 samples of vegetables and fruits from various counties and districts of Wenzhou City were collected for testing and analysis. Eventually, 23 types of pesticides with a detection rate greater than 5% and those exceeding the standard were selected for dietary intake risk assessment. ResultsFrom 2020 to 2023, the overall detection rate of pesticide residues in fruits and vegetables monitored in Wenzhou was 71.62%, with an overall exceedance rate of 5.27%. From the results of the monitoring of pesticide residues in fruits and vegetables, fresh legume vegetables had the highest detection rate of 90.00%. Among the six major categories of pesticides monitored, fungicides in vegetables and fruits had the highest detection rates of 68.18% and 85.03%, respectively. The highest exceedance rate in vegetables was organophosphorus pesticides, accounting for 2.85%, while in fruits, neonicotinoid pesticides had the highest exceedance rate of 3.21%. From the perspective of sampling time, the peak detection rate of pesticide residues in fruits and vegetables in Wenzhou occurred in June and October. The index of food safety (IFS) of the 23 pesticides with a detection rate higher than 5% ranged from 0.000 7 to 0.694 2 based on the 95% monitoring value of pesticide residues, which were all less than 1. Calculated at maximum content, the IFS values of dithiocarbamate (calculated by CS₂), chlorothalonil and propiconazole were all greater than 1, indicating that the maximum detection values of the three pesticides exceeded the acceptable safety risk. The risk level of acute dietary intake of the 23 pesticides ranged from 1.26% to 52.65%. ConclusionThe overall situation of pesticide residues in fruits and vegetables sold in Wenzhou from 2020 to 2023 is favourable, but the exceedance rate of pesticide in some fruits and vegetables is high. Special attention should be paid to the pesticide residues of fungicides, neonicotinoid insecticides and organophosphorus pesticides in fresh legume vegetables, bulb vegetables and some fruits sold in Wenzhou, such as acetamiprid in bayberry and cowpea, dimethomorph in strawberry, chlorpyrifos in leek, etc., and monitoring of pesticide residues in food need to be strengthened.

This paper summarized Professor BU He's clinical experience in the integrative internal and external treatment of pediatric functional constipation. He believes that dysfunction of the spleen in transportation leads to impaired function of the sanjiao （三焦） and intestinal obstruction， which constitutes the core pathogenesis of pediatric functional constipation. The treatment emphasizes regulating the spleen and harmonizing the pivot， as well as unblocking the bowel and eliminating stagnation. An integrated approach combining internal and external therapies is advocated. Internally， Chinese herbal medicine， primarily Modified Sijunzi Decoction and Shaoyao Gancao Decoction （四君子汤合芍药甘草汤加减） is used to regulate the internal organs. Externally， pediatric tuina and moxibustion on qi interlocking are employed. Together， these methods fortify the spleen and facilitate transportation， restoring the smooth function of the sanjiao pivot， and ensuring intestinal patency， thereby relieving constipation.

OBJECTIVE To systematically evaluate the methodological quality of the postoperative chemotherapy guidelines/ consensuses for ovarian epithelial tumor. METHODS A search was conducted across databases including PubMed， Embase， Web of Science， CBM， VIP， Chinese Medical Journal Data， Wanfang Data， and CNKI， as well as the official websites of GIN， NICE， Medlive， AHRQ， CSCO， ASCO， and NCCN. The search period was from the establishment of the databases/websites to March 10， 2025. The quality of the included guidelines/consensus was evaluated by using the AGREE-Ⅱ tool. RESULTS A total of 16 guidelines/consensuses were included. The domain scores of AGREE-Ⅱ evaluation were as follows： scope and purpose of 85.07%， participants of 47.92%， rigor of development of 57.49%， clarity of presentation of 88.02%， applicability of 8.20%， and independence of 53.39%. Among them， 14 were recommended at grade B and 2 were recommended at grade C. The subgroup analysis by different countries/regions and different types of studies showed that the scores for participants， rigor of development， and independence of the guidelines/consensuses in China were significantly lower than foreign countries （P＜0.05）； the scores for participants and rigor of development of the guidelines were significantly higher than consensuses （P＜0.05）. The guideline/ consensus recommendation results indicated that grade B guidelines/consensus recommend platinum-based combination chemotherapy as the preferred adjuvant chemotherapy regimen for stage Ⅰ high-grade serous carcinoma patients；platinum-based combination chemotherapy±bevacizumab was recommended as the preferred adjuvant chemotherapy regimen for stage Ⅱ-Ⅳ high- grade serous carcinoma patients and for platinum-sensitive recurrent high-grade serous carcinoma patients； non-platinum single- agent chemotherapy±bevacizumab was recommended as the preferred chemotherapy regimen for platinum-resistant recurrent high- grade serous carcinoma patients. CONCLUSIONS The overall quality of postoperative chemotherapy guidelines/consensuses for ovarian epithelial tumor is not high. The methodological quality of guidelines/consensuses in China is still lagging behind that of foreign countries. The recommendations differ from those in foreign countries. It is recommended to improve the aspects of participants， rigor of development， and independence， to recommend treatment plans based on the different stages of ovarian cancer， and develop guidelines/consensuses that align with China’s national conditions.

Objective To explore the roles of iron overload in pro-atherogenic activation of foam cells.Methods RAW264.7 and MOVAS cells were stimulated by oxLDL,ferrimine citrate and deferoxamine respectively.Prussian Blue and Oil Red O staining were used to detect iron deposition and foam cell.CCK-8 test,DHE probe,ELISA,RT-qPCR were performed to detect the cell death rate,reactive oxygen species(ROS)generation,lipid peroxidation molecules[glutathione peroxidase(GSH),glutathione peroxidase 4(GPX4),malondialdehyde(MDA)content]and the mRNA level of ATP binding cassette transporter A1(ABCA1),ATP binding cassette transporter G1(ABCG1),inductible nitris oxide synthase(iNOS),arginase-1(Arg-1),α-smooth muscle actin(α-SMA),smooth muscle 22 alpha(SM22a),osteopontin(OPN),Interleukin-1β(IL-1β),tumor necrosis factor-α(TNF-α).Results Iron overload could reduced reverse cholesterol transporters(ABCA1 and ABCG1),promote foam cells generation,increased cell death rate,induced the expression of lipid peroxidation molecules(GSH,GPX4,MDA),and promoted pro-inflammatory M1 marker of macrophage and synthetic marker expression of vascular smooth muscle cell(VSMC)and inflammatory cytokines(IL-1β,TNF-α).Conclusion Iron overload promotes the generation of foam cells derived from macrophages and smooth muscle cells and transform them into pro-atherosclerotic phenotype,aggravates cell lipid peroxidation and inflammatory reaction,which contributes to the progress of atherosclerosis.

Objective To investigate the clinical significance of ANCA in the disease activity of patients with SLE.Methods A total of 1 025 SLE patients were recruited and were divided into inactive and active groups according to SLEDAI score.Demographic characteristics,clinical symptoms,autoantibodies,routine laboratory tests and renal pathology were also recorded and compared between the two groups.Results All patients were divided into inactive group(n = 750)and active group(n = 250).The occurrence of renal,pulmonary,cutaneous,arthritis manifestations were significantly higher than those of the inactive group(all P<0.05).All patients were tested for ANCA,and the most common pattern being perinuclear or p-ANCA,the percentage of p-ANCA seroposi-tive increased greatly with the increased disease activity(P<0.05).The autoantibodies were further analyzed between the two groups,25 patients had reactivity to MPO,but no patient had reactivity to PR3.Also,there were significant differences in anti-dsDNA antibody,anti-nucleosome antibody between the two groups(P<0.05).In the active group,patients with p-ANCA seropositive exhibited higher serum beta-2-microglobulin(β2-MG),titers of anti-dsDNA antibody,SLEDAI scores,lower albumin,C3,and C4 levels(P<0.05).Meanwhile,p-ANCA was associated with IL-6,which increased significantly with the increase of SLEDAI score.In addition,patients with p-ANCA seropositive had more occurrence of lupus nephritis,but it had no association with the renal pathology.Conclusion The appearance of p-ANCA in SLE patients indicated more severe disease activity status.

A foodborne poisoning incident occurred in a street， Ouhai District， Wenzhou City， Zhejiang Province on May 9， 2023， which was caused by the accidental consumption of medicinal liquor containing aconitum alkaloids. Three individuals drank homemade aconite-containing medicinal liquor and were subsequently poisoned， of which two cases were severe， and one case was mild. All three patients exhibited symptoms such as numbness in the mouth， tongue and limbs， dizziness， fatigue， nausea， vomiting， and blurred vision. Two of them successively entered a state of shock and coma， with an incubation period of approximately 30 minutes. Among seven samples of suspected homemade medicinal liquor， one sample tested positive simultaneously for aconitine， neaconitine， hypaconitine， and benzoylaconitine， with concentrations of 62.3 mg·L^-1， 2.6 mg·L^-1， 17.7 mg·L^-1， and 31.6 mg·L^-1， respectively. Four kinds of aconite alkaloids were detected in all the urine， blood， and vomit samples from the patients， and the most toxic aconitine was detected at levels of 1.5 μg·L^-1， 5.9 μg·L^-1， and 26.2 μg·L^-1， respectively. Based on the field epidemiological investigation， combined with clinical manifestations and laboratory test results， it was determined that this incident was a case of food poisoning caused by the accidental consumption of medicinal liquor containing aconite. Due to timely rescue and proper treatment measures， all poisoned patients have recovered， with no fatalities. It is suggested that relevant authorities should strengthen the regulation of the processing and sale of aconite herbs and promote the awareness of food safety.

Objective: To explore the association between greenness surrounding school and aggression among primary school students, and to explore the potential mediating roles of social support, loneliness, particulate matter (PM2.5) and Nitrogen Dioxide (NO2) in this association, in order to provide a scientific reference for preventing and ameliorating aggressive behaviors of primary school students. Methods: The data was used from a survey of children and adolescents conducted in 2015. The Chinese version of the Buss-Warren Aggression Questionnaire was used to assess total and subtypes of aggression, and the mean values of normalized difference vegetation index (NDVI) of 100 m, 500 m, 1 000 m circular buffers surrounding school were used to indicate the participants greenness exposure. PM2.5 and NO2 datas were obtained from the China High Air Pollutants Dataset.Generalized Linear Mixed Models were used to assess the associations of greenness surrounding school with total and subtypes of aggression. Results: Per IQR increment of NDVI-500 m [OR(95%CI)=1.09(1.03-1.15)] and NDVI-1 000 m[OR(95%CI)=1.07(1.02-1.13)] were positively correlated with physical aggression among primary school children, and per IQR increment of NDVI-100 m [OR(95%CI)=0.94(0.90-0.99)], NDVI-500 m [OR(95%CI)=0.93(0.89-0.98)] and NDVI-1 000 m [OR(95%CI)=0.95(0.91-1.00)] were negatively associated with verbal aggression (P<0.05). Mediation analyses revealed that social support partially mediated the association between the NDVI-500 m and physical aggression (mediation ratio:18.0%) and verbal aggression (mediation ratio:-8.3%) among primary school students, and loneliness partially mediated the association between the NDVI-500 m and physical aggression and verbal aggression among elementary school students effects, with proportion mediated ratios of -10.0% and 21.0%, respectively (P<0.05). Conclusions Exposure to school surrounding greenness is likely to associated with physical aggression and verbal aggression in primary school students, and social support and loneliness may partially mediate these associations.

ObjectiveTo observe the effects of Coptidis Rhizoma-Fermentum Rubrum on non-alcoholic fatty liver disease （NAFLD） in mice and explore its possible mechanisms. MethodSixty male SPF C57BL/6J mice were randomly divided into six groups： control group， model group， low-， medium-， and high-dose Coptidis Rhizoma-Fermentum Rubrum group （0.75， 1.5， 3 g·kg^-1）， and metformin group （0.075 g·kg^-1）， with 10 mice in each group. NAFLD mouse models were induced by high-fat diet feeding for 24 weeks. The low， medium， and high-dose Coptidis Rhizoma-Fermentum Rubrum groups were administered corresponding doses of Coptidis Rhizoma-Fermentum Rubrum by gavage， while the control and model groups received an equivalent amount of saline for four weeks. Serum total cholesterol （TC）， triglycerides （TG）， free fatty acids （FFA）， and liver function markers including alanine aminotransferase （ALT） and aspartate aminotransferase （AST） were measured using an automatic biochemical analyzer. Hematoxylin-eosin （HE） and oil red O staining were used to detect liver lipid deposition， and Prussian blue staining was used to measure liver ferrous ion levels. Western blot was performed to detect the expression of key proteins in the nuclear factor erythroid-2-related factor 2 （Nrf2）-glutathione peroxidase 4 （GPX4） axis. ResultAfter 24 weeks of high-fat feeding， compared with the control group， the model group showed significant increases in body weight， liver weight and liver index， and serum lipid levels （P<0.01）， as well as substantial hepatic lipid deposition with marked steatosis. Compared with the model group， Coptidis Rhizoma-Fermentum Rubrum intervention reduced body weight （P<0.01）， liver weight and liver index （P<0.01）， and serum lipid levels （P<0.05， P<0.01）， improved liver function （P<0.01）， and decreased hepatic lipid deposition， with the low-dose Coptidis Rhizoma-Fermentum Rubrum group showing the best effect. Western blot results showed that compared with those in the control group， the expression levels of Nrf2， heme oxygenase-1 （HO-1）， kelch-like ECH-associated protein 1（Keap1）， and GPX4 proteins in the model group were decreased （P<0.05， P<0.01）. Compared with the model group， Coptidis Rhizoma-Fermentum Rubrum increased the expression levels of these proteins （P<0.05， P<0.01）. ConclusionCoptidis Rhizoma-Fermentum Rubrum can alleviate fatty liver in mice， improve liver function， and reduce hepatic lipid deposition， possibly by regulating the Nrf2/GPX4 ferroptosis axis.
