Objective To explore the correlation between the incidence of foodborne diseases and meteorological factors in Jinan, and to provide targeted measures for the prevention and control of foodborne diseases. Methods Data from the reporting systems of two sentinel hospitals for active surveillance of foodborne diseases from 2013 to 2021 in Jinan were collected. The meteorological data in the same period in Jinan were also collected. The generalized additive model was used to explore the nonlinear relationship between meteorological factors and the incidence of foodborne diseases, and threshold function analysis was use to perform subsection regression. Results The incidence of foodborne diseases was positively correlated with daily average temperature (r_s=0.23), relative humidity (r_s=0.05), and daily average wind speed (r_s=0.01), and negatively correlated with daily average air pressure (r_s=-0.19). Based on the GAM results and segmented regression analysis of meteorological factors, it was found that when the daily average temperature was below or above the threshold of 24.63°C, for every 1°C increase in daily average temperature, the incidence of foodborne diseases correspondingly increased by 0.04% and 0.18%. When the daily average wind speed was above the threshold of 2.26 m/s, the incidence of foodborne diseases decreased by 0.36% for every 1 m/s increase in the daily average wind speed. Conclusion Nine years of observation and data analysis have shown that meteorological factors such as daily average temperature, relative humidity, air pressure, and wind speed are related to the incidence of foodborne diseases. These findings suggest that meteorological factors may be important factors leading to foodborne diseases, which provides an important scientific basis for formulating effective prevention and control measures.

Objective:To explore the immunological characteristics of peripheral blood and genetic variations of 11 immunodeficiency virus(HIV)-negative children with Talaromyces marneffei(TM) infection, thus enhancing the diagnostic and therapeutic levels of TM infection in children. Methods:Clinical data of 11 HIV-negative children with TM infection who presented to Guangzhou Women and Children′s Medical Center, Guangzhou Medical University from January 2010 to December 2022 were retrospectively analyzed, including clinical characteristics, peripheral immune profile and genetic test results.Results:A total of 11 HIV-negative children with TM infections were recruited, involving 9 males and 2 females with a median age of 19 months.The main clinical manifestations were fever (10/11, 90.91%), cough (10/11, 90.91%) and hepatomegaly (7/11, 63.64%). Common severe complications included acute respiratory distress syndrome (7/11, 63.64%) and septic shock (5/11, 45.45%). Finally, 2 children died.Transient neutropenia occurred in 6 cases (6/11, 54.55%), and lymphocytopenia combined with serum immunoglobulin (Ig) G decrease was observed in 4 cases (4/11, 36.36%). IgA decrease, IgM decrease, IgE decrease, IgM increase and IgE increase were observed in 6 cases, 3 cases, 5 cases, 3 cases, and 2 cases, respectively.Both T-lymphocyte and B-lymphocyte counts decreases was observed in 1 case.Genetic testing was performed in all recruited children, and genetic variations were detected in all of them.Inborn errors of immunity (IEIs) were diagnosed in 8 cases, including 4 diagnosed as CD 40 ligand deficiency with CD40LG variation, 1 of severe combined immunodeficiency with IL2RG variation, 1 of Signal transduction and activator of transcription 3(STAT3)-hyper-IgE syndrome with STAT3 variation and 1 of familial candidiasis type 2 with CARD9 compound heterozygous mutations.In the other 3 cases, 2 carried genetic variations that were likely pathogenic, and 1 case was considered uncertain. Conclusions:The clinical manifestations of HIV-negative children with TM infection are atypical, which is characterized as serious complications and high mortality.Early identification and gene testing to detect potential IEIs can improve the prognosis of TM infection.

Objective To develop a nomogram for predicting the risks of early anastomotic recurrence(EAR)after primary bowel resection in patients with Crohn's disease(CD).Methods The patients with CD under-going preoperative magnetic resonance enterography(MRE)and primary bowel resection were enrolled in this retrospective study and divided into an EAR group(18 patients)and EAR-free group(12 patients).The EAR group included the patients having an endoscopic Rutgeerts score of≥I2 month or the need for anastomotic resection within 12 months after surgery.All the 38 indexes including preoperative demographic characteristics,laboratory examina-tions,multi-parameter MRE features of the resected intestine and its adjacent mesentery,histological findings,and postoperative pharmacotherapy were analyzed.Least absolute shrinkage and selection operator(LASSO)regression and multivariate binary logistic regression analysis were performed to identify independent risk factors to be incorpo-rated into the nomogram for predicting the risks of early anastomotic recurrence and the prediction performance was evaluated.Results Mesenteric creeping fat index on MRE and comb sign were independent risks of EAR,with a concordance index of 0.882(95%CI:0.764～1).The calibration plot revealed a strong relationship between actual observation and predicted probability of EAR.Conclusions The preoperative MRE-based nomogram may be a potential tool for predicting EAR following surgery in patients with CD,which is beneficial to individual management in those patients.It provides reference for the formulation of early postoperative individualized drug adjuvant therapy in patients at high risk of EAR.

Objective:To investigate the current situation and related factors of children's growth and development in drinking-water-borne endemic fluorosis areas after water improvement, and provide a basis for improving the control strategies.Methods:The stratified random sampling method was used to select children aged 7 to 13 in villages with different years of water improvement in Xi'an from November 2019 to June 2020. The height and weight of children were measured, and body mass index (BMI) was calculated. The height development level of children was graded according to the "Standard for Height Level Classification among Children and Adolescents Aged 7 - 18 Years" (WS/T 612-2018), and the physical development (BMI) level of children was determined according to the "Comprehensive Evaluation of Development Level for Children and Adolescents" (GB/T 31178-2014). At the same time, according to the standard of "Diagnosis of Dental Fluorosis" (WS/T 208-2011), the diagnosis of dental fluorosis in children was performed. The serum fluoride level was determined by ion selective electrode method, and the levels of other chemical elements (calcium, iron, magnesium, copper, zinc, iodine, selenium, lead, arsenic, cadmium, chromium, mercury, nickel) in blood were determined by inductively coupled plasma mass spectrometry.Results:A total of 469 children were included in the investigation. After water improvement, 67.38% (316/469) of the children in the disease area were at the moderate level of height development, 7.89% (37/469) were at the medium to upper and upper levels, and 24.73% (116/469) were at the medium to lower and lower levels. The BMI of the children in the emaciation group was 8.53% (40/469), while it was 10.87% (51/469) in the overweight group and 8.74% (41/469) in the obesity group. There was statistically significant difference in the distribution of height development level of children in areas with different water improvement years ( P = 0.005), but no statistically significant difference in BMI distribution ( P = 0.154). There was no significant difference in height development level and BMI distribution of children with or without dental fluorosis ( P > 0.05). There were significant differences in serum levels of iron and zinc among children with different height development levels ( P < 0.05). There were significant differences in serum levels of magnesium, copper, iodine and chromium among children with different BMI ( P < 0.05). Conclusion:The growth and development of children in drinking-water-borne endemic fluorosis area after water improvement are not correlated with the prevalence of dental fluorosis, but may be related to the levels of chemical elements such as iron, magnesium, copper, and iodine in the body.

Objective To explore the causal relationship between inflammatory protein markers and the risk of colorectal cancer using a Mendelian randomization(MR)approach.Methods We obtained data pertaining to colorectal cancer from Genome-Wide Association Study(GWAS)datasets and used 91 inflammatory protein markers as the exposure variables.A two-sample MR analysis model was used to assess the causal link between the inflammatory markers and colorectal cancer risk.The robustness of the results was evaluated through heterogeneity,pleiotropy,and sensitivity analyses using 5 MR models:Inverse Variance Weighted(IVW),Weighted Median,MR Egger,Simple Mode,and Weighted Mode.We examined the mRNA expressions of PD-L1,AXIN1,and β-NGF using RT-qPCR in 86 untreated patients with colorectal adenocarcinoma admitted in Nanfang Hospital between December,2021 and December 2023,and analyzed their correlation with the clinical characteristics of the patients.Results Using the IVW model,MR analysis revealed significant causal associations between a reduced risk of colorectal cancer and lowered expressions of AXIN1(OR=0.866,95%CI:0.754-0.994,P=0.040),β-NGF(OR=0.914,95%CI:0.843-0.990,P=0.028;OR=0.884,95%CI:0.784-0.998,P=0.047 using Weighted Median model),and PD-L1(OR=0.903,95%CI:0.824-0.989,P=0.028).No significant heterogeneity or pleiotropy was observed,indicating good stability of the results.Sensitivity analysis confirmed the reliability of the findings.The clinical study demonstrated a significant correlation between PD-L1 expression and TNM staging,particularly in stage IV patients(P=0.007).AXIN1 and β-NGF expression levels were significantly correlated with the degree of tumor differentiation,and their expressions were higher in poorly differentiated samples(P<0.001).Conclusion Lowered expressions of inflammatory protein markers AXIN1,β-NGF,and PD-L1 are causally correlated with a reduced risk of colorectal cancer and their expression levels are associated with TNM staging and tumor differentiation.These markers may thus serve as potential targets for colorectal cancer treatment and prevention.

Objective:To explore the impact of sleep duration, physical exercise, and their interactions on the risk of dyslipidemia in older adults aged ≥80 (the oldest old) in China.Methods:The study subjects were the oldest old from four rounds of Healthy Aging and Biomarkers Cohort Study (2008-2009, 2011-2012, 2014 and 2017-2018). The information about their demographic characteristics, lifestyles, physical examination results and others were collected, and fasting venous blood samples were collected from them for blood lipid testing. Competing risk model was used to analyze the causal associations of sleep duration and physical exercise with the risk for dyslipidemia. Restricted cubic spline (RCS) function was used to explore the dose-response relationship between sleep duration and the risk for dyslipidemia. Additive and multiplicative interaction model were used to explore the interaction of sleep duration and physical exercise on the risk for dyslipidemia.Results:The average age of 1 809 subjects was (93.1±7.7) years, 65.1% of them were women. The average sleep duration of the subjects was (8.0±2.5) hours/day, 28.1% of them had sleep duration for less than 7 hours/day, and 27.2% had sleep for duration more than 9 hours/day at baseline survey. During the 9-year cumulative follow-up of 6 150.6 person years (follow-up of average 3.4 years for one person), there were 304 new cases of dyslipidemia, with an incidence density of 4 942.6/100 000 person years. The results of competitive risk model analysis showed that compared with those who slept for 7-9 hours/day, the risk for dyslipidemia in oldest old with sleep duration >9 hours/day increased by 22% ( HR=1.22, 95% CI: 1.07-1.39). Compared with the oldest old having no physical exercise, the risk for dyslipidemia in the oldest old having physical exercise decreased by 33% ( HR=0.67, 95% CI: 0.57-0.78). The RCS function showed a linear positive dose-response relationship between sleep duration and the risk for hyperlipidemia. The interaction analysis showed that physical exercise and sleep duration had an antagonistic effect on the risk for hyperlipidemia. Conclusion:Physical exercise could reduce the adverse effects of prolonged sleep on blood lipids in the oldest old.

Objective To explore the causal relationship between inflammatory protein markers and the risk of colorectal cancer using a Mendelian randomization(MR)approach.Methods We obtained data pertaining to colorectal cancer from Genome-Wide Association Study(GWAS)datasets and used 91 inflammatory protein markers as the exposure variables.A two-sample MR analysis model was used to assess the causal link between the inflammatory markers and colorectal cancer risk.The robustness of the results was evaluated through heterogeneity,pleiotropy,and sensitivity analyses using 5 MR models:Inverse Variance Weighted(IVW),Weighted Median,MR Egger,Simple Mode,and Weighted Mode.We examined the mRNA expressions of PD-L1,AXIN1,and β-NGF using RT-qPCR in 86 untreated patients with colorectal adenocarcinoma admitted in Nanfang Hospital between December,2021 and December 2023,and analyzed their correlation with the clinical characteristics of the patients.Results Using the IVW model,MR analysis revealed significant causal associations between a reduced risk of colorectal cancer and lowered expressions of AXIN1(OR=0.866,95%CI:0.754-0.994,P=0.040),β-NGF(OR=0.914,95%CI:0.843-0.990,P=0.028;OR=0.884,95%CI:0.784-0.998,P=0.047 using Weighted Median model),and PD-L1(OR=0.903,95%CI:0.824-0.989,P=0.028).No significant heterogeneity or pleiotropy was observed,indicating good stability of the results.Sensitivity analysis confirmed the reliability of the findings.The clinical study demonstrated a significant correlation between PD-L1 expression and TNM staging,particularly in stage IV patients(P=0.007).AXIN1 and β-NGF expression levels were significantly correlated with the degree of tumor differentiation,and their expressions were higher in poorly differentiated samples(P<0.001).Conclusion Lowered expressions of inflammatory protein markers AXIN1,β-NGF,and PD-L1 are causally correlated with a reduced risk of colorectal cancer and their expression levels are associated with TNM staging and tumor differentiation.These markers may thus serve as potential targets for colorectal cancer treatment and prevention.

Objective:To analyze the incidence and progression of overactive bladder(OAB)symp-toms following radical prostatectomy for prostate cancer patients and to identify related risk factors.Methods:A retrospective study was conducted on 263 local stage prostate cancer patients who underwent radical prostatectomy at Peking University Third Hospital from January 2013 to May 2017.Clinical base-line information,comprehensive imaging features,perioperative parameters,preoperative urinary control status,pathological diagnosis,and the incidence of OAB within one year postoperatively were collected and analyzed.In the imaging features,two parameters were defined:Bladder wall thickness(BWT)and bladder mucosal smoothness(BMS),which were used to predict the occurrence of OAB.Patients were evaluated based on their clinical baseline characteristics,including age,body mass index(BMI),co-morbidities,and prostate-specific antigen(PSA)levels.The imaging characteristics were assessed using preoperative MRI,focusing on BWT and BMS.Perioperative parameters included operative time,blood loss,and length of hospital stay.The OAB symptoms were assessed using the overactive bladder symptom score(OABSS)and the international prostate symptom score(IPSS).These scores were correlated with the postoperative incidence of OAB.Results:Among the 263 patients who underwent radical prostatecto-my,52(19.8％)exhibited OAB within one year postoperatively.Of the 40 patients with preoperative OAB symptoms,17(42.5％)showed remission postoperatively,while 23(57.5％)had persistent symptoms.Additionally,29 patients developed new-onset OAB,accounting for 55.77％of all postopera-tive OAB cases.Univariate analysis indicated that BWT,BMS,OABSS,and IPSS score were all associ-ated with the occurrence of postoperative OAB.Further multivariate analysis identified BMS as an inde-pendent risk factor for long-term OAB(P＜0.001).Conclusion:Long-term postoperative overactive bladder is a common complication following radical prostatectomy.The findings suggest that preoperative MRI measurements of bladder wall thickness and bladder mucosal smoothness during bladder filling phase can predict the risk of OAB occurrence postoperatively.Identifying these risk factors preoperatively can help in counseling patients about potential complications and in developing strategies to mitigate the risk of developing OAB after surgery.Early detection and management of these parameters might improve the quality of life for patients undergoing radical prostatectomy.

Alzheimer disease(AD)is a common neurodegenerative disease with overall cognitive deterioration and mental and behavioral disorders,and due to unknown etiology and pathogenesis of AD,there is currently no effective medi-cation for AD.As a new noninvasive neuromodulation method,repetitive transcranial magnetic stimulation(rTMS)can improve cognitive impairment in patients with AD by regulating multiple pathways such as neural activity,synaptic plastic-ity,neurotransmitters,and neurotrophic factors.This article reviews the studies on the mechanism of action of rTMS in the treatment of AD in recent years,in order to clarify the mechanisms of rTMS such as anti-oxidation and regulation of synaptic plasticity.
