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 (rs=0.23), relative humidity (rs=0.05), and daily average wind speed (rs=0.01), and negatively correlated with daily average air pressure (rs=-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.

ObjectiveTo explore the interaction among root fungi of Stellaria dichotoma var. lanceolata, soil factors, and main components of medicinal materials in lithosol habitats. MethodHigh-throughput sequencing technology was employed to determine the fungal community of the root system of S. dichotoma var. lanceolata at different levels (bulk soil, rhizosphere soil, rhizoplane soil, and root interior) and the soil properties of the root system (bulk and rhizosphere), and the relationship among the fungal community, soil properties, and the main components of medicinal materials was analyzed. ResultThe total phosphorus, available phosphorus, alkaline nitrogen, dissolved organic carbon, and soil water content in the rhizosphere soil of S. dichotoma var. lanceolata were slightly higher than those in the rhizosphere, but the difference was not significant. Ascomycota is the dominant phylum of root fungi in S. dichotoma var. lanceolata. In the progressive level of bulk-rhizosphere-rhizoplane-root interior system, although the fungal diversity gradually decreased, the abundance of Hypocreales, a new phylum (unclassified_ k_ Fungi), Helotiales, and Natipusilales gradually increased, among which Hypocreales is the most important fungal group in the root system of S. dichotoma var. lanceolata. The structural equation model (SEM) shows that the physicochemical factors of the root-soil play an important regulatory role in the fungal community and the main components of medicinal herbs, with soil total nitrogen, alkaline nitrogen, soil water content, and pH being the main regulatory factors. Soil nitrogen content is the key to promoting the main components of the medicinal herbs, and Penicillium fungi are the key fungal group to regulate the main components of the medicinal herbs. ConclusionIt highlights that the physicochemical properties of the soil of S. dichotoma var. lanceolata play a crucial role in the fungal community and the components of medicinal materials. Hypocreales fungi in the root of S. dichotoma var. lanceolata were an important group, and Penicillium fungi had a certain role in mediating the components of medicinal materials.

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 explore the characteristics and regulations of adverse drug reactions (ADR) caused by apatinib, and to provide a reference for the safe use of apatinib in clinic. METHODS Case and group reports on ADR and safety evaluation of apatinib were retrieved from Chinese and English databases such as CNKI, Wanfang medical network, VIP and PubMed since its listing in 2014, literature data were extracted and statistically analyzed after screening. RESULTS Totally 101 cases were included, involving 221 ADR. In the above cases, the male-to-female ratio was 1.24∶1, with the highest proportion of patients aged 51 to 70 years, most of the patients were given a dose of 500 mg or more, and the patients given low dose of apatinib combined with other antitumor drugs were also likely to have ADR. One to two types of adverse reaction were the most common, while the types could reach up to six. Most ADR occurred within 30 days after medication, and the systems/organs involved were mainly the cardiovascular system damage,skin and its accessories damage, gastrointestinal system damage and urinary system damage; the main clinical manifestations were hypertension/aggravation,hand-foot syndrome,abdominal pain diarrhea and albuminuria, etc. Hypertension/aggravation, hand-foot syndrome and myelosuppression were the most common serious ADR. Most ADR could be improved/cured by suspension of administration, dose downregulation and symptomatic treatment. All 4 patients who died had underlying diseases, and their ECOG scores all ≥2 points. Special ADR (such as reversible posterior encephalopathy syndrome, psychiatric disorders, and cognitive impairment) were mostly caused by apatinib itself, or may be caused by apatinib in combination with the primary or underlying disease. CONCLUSIONS Advanced age, large dose, combination medication, underlying diseases and poor physical condition might be the high risks for ADR caused by apatinib. It is recommended to monitor the blood pressure,urine protein and skin of hands and feet of all patients with medication on a daily basis,pay attention to the occurrence of special ADR, and timely detect abnormal states and give effective intervention,so as to avoid the aggravation of ADR and other secondary ADR.

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 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.
