Objective: To explore the association between meat consumption and anxiety symptoms in first year junior high school students in Yunnan Province, and to provide theoretical support for preventing and relieving anxiety symptoms in junior high school students. Methods: From October to December 2022, a random cluster sampling method was used to select 8 500 first year junior high school students from 11 counties in Yunnan Province as the survey subjects for a questionnaire survey. The study used Food Frequency Questionnaire and the Chinese version of the Depression Anxiety Stress Scale-21 (DASS-21) to assess the meat consumption and anxiety symptoms of junior high school students.The distribution differences in anxiety symptoms among first year junior high school students with different demographic characteristics were analyzed statistically by using the Chi-square test,and the association between meat consumption and anxiety symptoms in students was analyzed by using a generalized linear model. Results: The detection rate of anxiety symptoms was 48.47%. After controlling for demographic variables and confounding factors, the consumption of livestock meat, poultry meat, processed meat, cured meat, barbecued meat and raw skin meat was statistically significant with anxiety symptoms ( β =-0.05, 0.04, 0.04, 0.08, 0.14, 0.17, all P <0.05). Stratified by ethnicity, The consumption of livestock meat, cured meat and barbecue was statistically correlated with anxiety symptoms in Han adolescents ( β =-0.07, 0.14, 0.22 ); the consumption of processed meat and raw skin meat was statistically correlated with anxiety symptoms in ethnic minority adolescents ( β =0.08, 0.18) (all P <0.05). Conclusions There is a statistical association between meat comsumption and the risk of anxiety symptoms in first year junior high school students in Yunnan Province. Guidance on meat consumption should be strengthened to prevent the occurrence of anxiety symptoms.

Non-alcoholic fatty liver disease(NAFLD)is a metabolic disease characterized by abnormal deposition of lipid in hepatocytes.If not intervened in time,NAFLD may develop into liver fibrosis or liver cancer,and ultimately threatening life.NAFLD has complicated etiology and pathogenesis,and there are no effective therapeutic means and specific drugs.Currently,insulin sensitizers,lipid-lowering agents and hep-atoprotective agents are often used for clinical intervention,but these drugs have obvious side effects,and their effectiveness and safety need to be further confirmed.Adenosine monophosphate(AMP)-activated protein kinase(AMPK)plays a central role in maintaining energy homeostasis.Activated AMPK can enhance lipid degradation,alleviate insulin resistance(IR),suppress oxidative stress and inflammatory response,and regulate autophagy,thereby alleviating NAFLD.Natural herbal medicines have received extensive attention recently because of their regulatory effects on AMPK and low side effects.In this article,we reviewed the biologically active natural herbal medicines(such as natural herbal medicine formulas,extracts,polysaccharides,and monomers)that reported in recent years to treat NAFLD via regulating AMPK,which can serve as a foundation for subsequent development of candidate drugs for NAFLD.

Endothelial dysfunction is a key factor linking obstructive sleep apnea hypopnea syndrome(OSAHS)with cardiovascular diseases.In this study,we used advanced proteomics and metabolomics approaches to investigate the impact of extracellular vesicles(EVs)derived from the serum of OSAHS patients on endothelial function.Our multi-omics analysis identified dysregulated pathways related to fatty acid metabolism,apoptosis regulation,and inflammatory responses,highlighting fatty acid synthase(FASN)as a crucial player in OSAHS-induced endothelial dysfunction.Both in vitro and in vivo experiments demonstrated that FASN-enriched EVs impair endothelial cell viability and disrupt metabolic homeo-stasis,offering new insights for the development of targeted therapies for cardiovascular complications associated with OSAHS.

Objective:To analyze the differences in routine blood tests and infection markers among elderly AIDS patients with other opportunistic infections, to explore their immune status and inflammatory responses, and to provide new molecular markers for clinical diagnosis.Methods:The study included general indicators, routine blood tests, and infection markers of older HIV patients with other opportunistic infections admitted to Beijing You'an Hospital, Capital Medical University, from January 1, 2014, to December 31, 2024.Statistical analysis was performed using SPSS 27.0 software, with a significance level set at P<0.05. Results:A total of 94 elderly AIDS patients with various opportunistic infections were included in this study.Among them, the majority were co-infected with tuberculosis, accounting for 60 cases(63.83%), followed by 23 cases(24.47%)of AIDS patients co-infected with syphilis.Additionally, there were 7 cases of AIDS co-infected with amoebiasis(7.45%)and 4 cases of AIDS co-infected with monkeypox(4.26%).Almost all cases of combined infections were male, with males comprising 91.3% of AIDS patients co-infected with syphilis and 100% in the other co-infected groups.There were 9 blood routine and infectious markers that exhibited significant differences between patients with HIV co-infected with tuberculosis and those with other opportunistic infections.These markers included lymphocytes(LYM), hemoglobin(HGB), erythrocyte sedimentation rate(ESR), C-reactive protein(CRP), procalcitonin(PCT), T lymphocytes, CD4 + T cells, CD8 + T cells, and the CD4/CD8 ratio( P<0.05).Specifically, the levels of LYM, HGB, T lymphocytes, CD4 + T cells, CD8 + T cells, and the CD4/CD8 ratio in elderly AIDS patients with tuberculosis were significantly lower than those in patients with other co-infections(all P<0.05).Conversely, the levels of inflammatory factors such as PCT, ESR, and CRP were notably higher in the former group(all P<0.05).The receiver operating characteristic(ROC)curve analysis revealed that when LYM was utilized as an individual indicator for the differential diagnosis between AIDS patients with tuberculosis and those with other opportunistic infections, the area under the curve(AUC)amounted to 0.832.However, the CRP/LYM ratio demonstrated the optimal diagnostic performance in differential diagnosis, with an AUC reaching 0.866. Conclusions:The immune function of elderly AIDS patients is further compromised following co-infection with tuberculosis, which is accompanied by a severe inflammatory response.The CRP/LYM ratio shows promise as a hematological molecular marker for differentiating between AIDS patients with tuberculosis and those with other opportunistic infections.

Objective To investigate the application of flipped classroom combined with teaching film-reading model in the teaching of filamentous fungal morphology for refresher doctors and evaluate its effect.Methods Fifteen refresher doctors taking microbiology from the 2022 batch of Guangdong Provincial People's Hospital were selected as the control group,and fifteen from the 2023 batch were se-lected as the experimental group.The"Morphological identification of Aspergillus and Mucor" was selected as the teaching content.The experimental group adopted flipped classroom combined with teaching film-reading model for teaching and the control group adopted tra-ditional teaching mode.The theoretical scores,operational scores,film-reading scores,and total scores of the two groups before and af-ter the implementation of teaching were compared and the teaching effect of the experimental group was evaluated using the Question-naire Star.Results The median scores of operational,film-reading,and total scores in the experimental group and control group were 40,30,and 95.5 and 36,27,and 85.5,respectively,and all the three scores in the experimental group were significantly higher than those in the control group(P＜0.05).Conclusion The flipped classroom combined with teaching film-reading model helps to improve the teaching effect of filamentous fungal morphology for refresher doctors,with high satisfaction,and can provide reference for subse-quent filamentous fungal morphology teaching.

OBJECTIVE To understand the disinfectant-resistant genes in the gram-negative bacteria isolated from the dirt retention on air recure filters of air conditioners and observe the drug resistance.METHODS The dirt re-tention samples were collected from the air return filters of air conditioners of some wards in 3 hospitals of Wuhan(Tongji Hospital of Tongji Medical College of Huazhong University of Science and Technology,Wuhan Central Hospital,and Hubei Provincial Maternal and Child Health Hospital)from 2018 to 2024.The gram-negative bac-teria were screened out,the disinfectant-resistant genes in the strains were detected by polymerase chain reaction(PCR),and the results of drug susceptibility test were analyzed.RESULTS Of 354 dirt retention samples that were collected from the air return filers of air conditioners,77 were detected with 138 strains of gram-negative bacteria,87 of which were Acinetobacter baumannii,50 were Enterobacteriaceae,and 1 was Pseudomonas aerug-inosa.The detection rates of qacEΔ1,qacEΔ1-sul1,aceI and qacA/B were 73.19％,82.61％,69.57％and 2.90％,respectively.None of the strains were detected with qacC,qacH or qacJ.The result of drug susceptibility test showed that 76.81％of the gram-negative bacteria were resistant to at least 1 type of antibiotic;93 strains of multidrug-resistant gram-negative bacteria were isolated,most of which were isolated from intensive care unit(ICU).The detection rates of qacEΔ1 and qacEΔ1-sul1 were higher in the drug-resistant strains than those in the non-drug-resistant strains;there were significant differences in the drug resistance rates to carbapenems,quin-olones and β-lactams between the qacEΔ1-sul 1-positive strains and the qacEΔ1-sul1-negative strains(P＜0.05).CONCLUSIONS There are drug-resistant gram-negative bacteria contaminations in some wards of the 3 hospitals in Wuhan.The carrying rates of disinfectant-resistant genes of the strains are high,and the strains show varying degree of resistance to the commonly used antibiotics;the strains carrying the qacEΔ1-sul1 have certain statistical association with the drug resistance.It is suggested that the hospital should take targeted disinfec-tion measures for the environment and reasonably use antibiotics.

Objective:To evaluate value of CT perfusion in evaluating the efficacy of different vascular reconstruction methods in the treatment of adult ischemic moyamoya disease.Methods:The clinical data of 80 adult patients with moyamoya disease with ischemic blood type who received revascularization in the Affiliated Hospital of Jining Medical University from February 2019 to February 2023 were retrospectively analyzed, including 43 patients who received superficial temporal arterio-middle cerebral artery anastomosis (direct group) and 37 patients who received brain-dural arterio-artery vascularization (indirect group). The improvement of clinical symptoms, Modified Rankin Scale (mRS) Score, collateral vessels and CTP parameters were compared between the two groups.Results:The improvement of clinical symptoms in the direct group was better than that in the indirect group ( P<0.05), and the significant remission rate was significantly higher than that in the indirect group [86.0%(37/43) vs 59.5%(22/37), χ 2=7.262, P=0.007]. The postoperative mRS score in the direct group was significantly lower than that before surgery [0(0, 1) vs 1(1, 2), Z=5.550, P<0.001]. The score of mRS After surgery in the indirect group was significantly lower than that before surgery [0(0, 1) vs 1(1, 2), Z=4.281, P<0.001], but there was no statistically significant difference between the two groups ( P>0.05). There was no significant difference in digital subtraction angiography (DSA) collateral vessel formation between the two groups ( P>0.05). The CTP parameters of the two groups before and after surgery were consistent between observers and within observers [intraclass correlation coefficient (ICC) range 0.88-0.94]. In the operation area, the relative cerebral blood flow (rCBF) after surgery was significantly increased, and the relative time to peak (rTTP) and relative mean transit time (rMTT) were significantly decreased in both groups, with statistical significance ( P<0.05). In the ipsilateral basal ganglia and frontal lobe, rCBF in the direct group was significantly increased, rTTP and rMTT were significantly decreased, and the differences were statistically significant (all P<0.05), while there were no statistically significant differences in parameters in the indirect group (all P>0.05). The changes of rCBF, rTTP and rMTT in the operative area in the direct group were better than those in the indirect group, and the changes of rCBF, rTTP and rCBF in the basal ganglia and frontal lobe were better than those in the indirect group, with statistical significance (all P<0.05), while there were no statistically significant differences in the remaining parameters (all P>0.05). Conclusions:CT perfusion is of great value in evaluating the difference of clinical symptom improvement in the treatment of adult ischemic moyamoya disease with different vascular reconstruction methods.

To summarize the clinical practice of continuous medical service for patients at Shanghai Children′s Medical Center, affiliated with Shanghai Jiao Tong University School of Medicine, from September 2023 to December 2024, following the approval of its extended care qualification. This study utilized a mixed-methods research design that integrates quantitative and qualitative approaches. The quantitative study included a total of 117 subjects, with an age range of 18 to 35 years, an average age of 21.56 years, and a median age of 19 years; there were 59 males and 58 females. The disease types covered four major categories: childhood leukemia and solid tumors (68 cases), congenital structural malformations (25 cases), congenital hereditary metabolic diseases (4 cases), and rare diseases (20 cases). Among the subjects, 57.26% (67 cases) were first-time visitors to SCMC. The patients came from 20 provinces, autonomous regions, and municipalities across the country, with 88.03% (103 cases) from outside Shanghai. The treatment outcomes showed improvement or cure in 80.34% (94 cases) of the subjects, and there were no medical complaints. In addition, a qualitative study was conducted to deeply explore the experiences, confusions, and challenges of receiving or implementing continuous medical services from the perspectives of patients and their families, as well as medical staff. According to the inclusion and exclusion criteria, a total of 44 subjects were included in the study, among them, there were 12 patients, 12 family members who were taking care of the patients in SCMC, and 20 corresponding medical staff members. The results of the qualitative study showed that trust in the attending physicians of the children′s specialty hospital, a good doctor-patient relationship, satisfactory treatment outcomes, and support from medical insurance policies are the main driving forces for patients over 18 years old to receive continuous treatment at children′s specialty hospitals. The medical staff of the hospital also believed that this model can promote patient benefits. In conclusion, under the policy support of the Shanghai Municipal Health Commission, the "Six Fixed" Model for continuous treatment established by SCMC has achieved certain positive results in practice. This provides practical references for the development of continuous treatment in China and offers new strategies for the application of preventive medicine in the field of children′s health.

Objective:To explore the effect of health status on the elder care choice,providing empirical evidence to optimize care provision and deepen the understanding of family risk-coping mechanisms.Method:Multinomial Logit model was used to examine the effects of health stock and health changes on the elder care choice,followed by an income heterogeneity analysis.Results:The impact of health status on the choice of elder care arrangements exhibited clear pathway differentiation and group heterogeneity.In the long-term effect,poor baseline cognitive ability was a key factor driving the elderly to turn to their children for elderly care,with each one-point decrease in the MMSE score increasing this probability by an average of 0.5 percentage points.In the short-term effect,an acute deterioration in either physical function(ΔADL)or cognitive ability(ΔMMSE)significantly increased the likelihood of transitioning to living with children,with the probabilities increasing by an average of 1.7 and 0.3 percentage points,respectively.In contrast,transitioning to institutional care—in both the long and short term—was driven solely by the deterioration of physical function,increasing the probability by 0.4 and 0.3 percentage points,respectively.The heterogeneity analysis further revealed that these clear decision pathways hold primarily for the high-income group,while the elder care choice of the low-income group was less sensitive to health indicators.Conclusion:The elder care choice is not solely determined by health risks but is a social process where health status and family economic resources are closely intertwined,ultimately manifesting as a divergence between the"strategic choices"of high-income groups and the"constrained reactions"of low-income groups.

Objective:To investigate the clinical manifestation, therapy, and prognosis of Susac syndrome and enhance the understanding of this disease.Methods:A case summary was made.The clinical data of two siblings with Susac syndrome treated at Children′s Medical Center, Peking University First Hospital in January 2024 were summarized.Reported cases of pediatric Susac syndrome were reviewed.Results:The onset of the disease in the two siblings was at the age of 3.00 and 6.75 years, with recurrent headaches, tinnitus, hearing loss and encephalopathy symptoms.Cranial magnetic resonance imaging showed multiple cerebral microbleeding and microinfarction lesions, " snowball like" in the corpus callosum and diffuse white matter edema in the brain.Audiometry revealed sensorineural hearing loss.In one case, ophthalmic fluorescein angiography revealed ischemic changes due to branch retinal artery occlusions.No pathogenic variants were detected in gene testing.This child was diagnosed with Susac syndrome, and the symptoms were improved after treatment with Corticosteroids and Rituximab.No relapse was observed during the 9-month follow-up.A total of 20 pediatric cases of Susac syndrome were retrieved, including 18 reported previously and 2 cases from this study.There were 2 boys and 18 girls, with the age of onset ranging from 2.5 to 17.0 years.The common initial symptoms included headache (19 cases), vertigo and tinnitus or hearing loss (9 cases), and vision impairment or visual field defect (4 cases). The symptoms were improved after immunotherapy.Conclusions:With a low incidence, Susac syndrome is rare in children and difficult to diagnose.There may be a genetic predisposition in such disease.Early diagnosis and immunotherapy can low the relapse and improve the prognosis.
