Objective: To examine the changing trajectories of sleep problems and teacher support among first year middle school students and their covariant relationship,so as to provide theoretical basis for the prevention strategy of sleep problems for the first year junior high school students. Methods: In September 2020, a multistage cluster random sampling method was used to select 1 027 first year junior high school students from two schools of Anshun and Guiyang cities in Guizhou Province for survey and follow up assessments (T1:September 2020, T2:October 2020, T3:November 2020, T4:December 2020). The Student Perceived Teacher Support Behavior Questionnaire and Pittsburgh Sleep Quality Index Scale were administered to assess sleep problems and teacher support among first year junior high school students. Spearman correlation analysis was used to examine the relationship between sleep problems and teacher support. A multivariate latent growth curve model was employed to analyze the changing trajectories and covariant relationship between teacher support and sleep problems, followed by a multi group analysis. Results: For first year junior high school students, teacher support scores at T1-T4 were 4.00 (3.47, 4.53), 4.00 (3.47, 4.58), 3.95 (3.47, 4.61) and 4.00 (3.48, 4.67), respectively; sleep problem scores were 0.83 (0.50, 1.17), 0.67 (0.50, 1.17), 0.83 (0.50, 1.17) and 0.67 (0.33, 1.17), respectively. Spearman correlation analysis revealed that teacher support and sleep problems were negatively correlated across all four period ( r =-0.28 to -0.14, all P <0.01). Teacher support perceived by students showed a linear increasing trend (intercept=3.98, slope=0.02), while sleep problems showed a linear decreasing trend (intercept=0.86, slope= -0.02 ) (all P <0.05). The multivariate latent growth model indicated that the rate of increase in teacher support after enrollment effectively predicted the rate of decrease in sleep problem levels ( β=-0.34, P <0.01). Multigroup analysis showed that the covariant relationship was not moderated by gender or boarding status (both P >0.05). Conclusions The increase in teacher support experienced by first year junior high school students during the transition period after enrollment, accompanied by a reduction in sleep problems, constitutes a dynamic protective process. The process is not moderated by gender or boarding status.

Objective: Previous studies have discovered a correlation between cigarette smoking and cortical thickness and surface area, but the causal relationship remains unclear. The objective of this investigation is to scrutinize the causal association between them. Methods: To derive summary statistics from a genome-wide association study (GWAS) on cortical thickness, surface area, and four smoking behaviors: 1) age of initiation of regular smoking (AgeSmk); 2) smoking initiation (SmkInit); 3) smoking cessation (SmkCes); 4) cigarettes per day (CigDay). Linkage disequilibrium score regression (LDSC) was employed to examine genetic association analysis. Furthermore, for traits with significant genetic associations, Mendelian randomization (MR) analyses were conducted. Results: The LDSC analysis revealed nominal genetic correlations between AgeSmk and right precentral surface area, left caudal anterior cingulate surface area, left cuneus surface area, left inferior parietal surface area, and right caudal anterior cingulate thickness, as well as between CigDay and left caudal middle frontal surface area, between SmkCes and left entorhinal thickness, and between SmkInit and left rostral anterior cingulate surface area, right rostral anterior cingulate thickness, and right superior frontal thickness (rg=-0.36–0.29, p<0.05). MR analysis showed a unidirectional causal association between left caudal middle frontal surface area and CigDay (βIVW=0.056, pBonferroni=2×10-4). Conclusion Left caudal middle frontal surface area has the potential to serve as a significant predictor of smoking behavior.

Objective To investigate the therapeutic effects of combined magnetic and electrical stimulation with an"intelligent exercise prescription"and novel matrix radiofrequency therapy in patients with pelvic organ prolapse(POP).Methods A total of 158 patients with POP who received treatment at the Gynecological Pelvic Floor Rehabilitation Center of the Eighth Affiliated Hospital of Southern Medical University between October 2022 and July 2025 were retrospectively enrolled and divided into an observation group(n=64)and a control group(n=94)based on their treatment plans.The control group underwent magnetic and electrical stimulation combined with an"intelligent exercise prescription"regimen.Specifically,patients received 10 sessions of electrical stimulation,5 sessions of magnetic stimulation,and performed 15～20 minutes of daily home exercise training guided by the"intelligent exercise prescription."The observation group received,in addition to the aforementioned treatments,four sessions of novel matrix radiofrequency therapy.Changes in the muscle strength grades of type Ⅰ and type Ⅱ pelvic floor muscles,Glazer surface electromyography(EMG)values,and POP-Q staging were compared between the two groups before and after treatment.Results After treatment,both groups demonstrated significant improvements in type Ⅰ and type Ⅱ muscle fiber strength compared to baseline(all P<0.05),with the observation group showing greater improvement in type Ⅰ muscle fiber strength than the control group(P<0.05).The muscle potential values of the observation group during rapid contraction,tense contraction,and endurance contraction stages were markedly increased compared to pre-treatment levels.Moreover,the muscle potential values during the pre-resting stage were significantly reduced after treatment(P<0.05).In the observation group,POP-Q grades of the anterior vaginal wall,uterus,and posterior vaginal wall were all significantly lower post-treatment than pre-treatment(all P<0.05).However,no statistically significant differences were observed between the observation group and the control group in these parameters(P>0.05).Both groups exhibited relatively high compliance rates(both≥75.0%),with no significant difference between them(P>0.05).The treatment cost for the observation group was significantly higher than that for the control group(P<0.05).Conclusions The combination of magneto-electrical stimulation,an"intelligent exercise prescription,"and novel matrix radiofrequency therapy can significantly improve pelvic floor muscle strength and muscle potential values in the short term,compared to pre-treatment levels.This integrated approach also effectively alleviates the prolapse of the anterior vaginal wall,uterus,and posterior vaginal wall.Furthermore,the combination of magnetic and electrical stimulation,"intelligent exercise prescription,"and matrix radiofrequency therapy demonstrates superior efficacy in enhancing type Ⅰ pelvic floor muscle fiber strength when compared to the combination of magnetic and electrical stimulation with"intelligent exercise prescription"alone.However,this treatment protocol entails a relatively high economic burden,and its clinical application should be carefully evaluated in consideration of patients'functional needs and financial conditions.

To explore the immunomodulatory effects of a new vegetable oil adjuvant(named E515)containing vitamin E(VE)and ginsenosides(GS)on rabbit peripheral blood lymphocytes and Bordetella of rabbit inactivated vaccine.E515,Bordetella bronchiseptica(Bb)and LPS were co-cultured with rabbit peripheral blood lymphocytes in vitro,and the lymphocyte conversion rate was detected by CCK8 method,and the content of lymphocyte supernatant cytokines was detected by ELISA method.After rabbits were immunized with E515-Bb vaccine,the antibody level was detec-ted by indirect ELISA,the serum cytokine content was detected by ELISA,and the protective effect of E515-Bb vaccine on rabbits was observed by challenge test.In vitro cell experiments showed that E515 could significantly increase lymphocyte proliferation and TH1/TH2 cytokine se-cretion in rabbit peripheral blood.In vivo animal experiments showed that E515 adjuvant could sig-nificantly enhance the level of Bb specific antibody induced by Bordetella vaccine in rabbits.In-crease the secretion level of TH1/TH2 cytokines and decrease the secretion level of TNF-α;It can effectively protect rabbits against Bordetella infection with a protection rate of 91.67％.Therefore,E515 as a new vegetable oil adjuvant deserves further study.

Objective:To study the relationship between serum levels of angiopoietin-2 (Ang-2), insulin-like growth factor 1 (IGF-1), immune factors, and prognosis in patients with uterine fibroids.Methods:A case-control study was conducted involving 93 patients with uterine fibroids who underwent laparoscopic myomectomy at The First People's Hospital of Longnan City between June 2021 and June 2023. These patients constituted the study group. Additionally, 104 healthy women undergoing routine health check-ups during the same period were selected as the control group. Based on the prognosis of the patients in the study group, they were further divided into two subgroups: a good prognosis group ( n = 42) and a poor prognosis group ( n = 46). The correlations among serum levels of Ang-2, IGF-1, immune factors, and prognosis were analyzed in the study group compared to the control group, as well as between the good prognosis and poor prognosis groups. Results:Four cases from the control group and five cases from the study group were excluded from the analysis. In the study group, serum levels of Ang-2 and IGF-1 were found to be (303.18 ± 42.39) mg/L and (1377.11 ± 84.78) mg/L, respectively. Both levels were significantly higher than those in the control group [(231.25 ± 34.18) mg/L, (438.09 ± 52.15) mg/L, t = 12.87, 19.63, both P < 0.001]. Additionally, CD 8+ levels in the study group were higher than those in the control group ( t = -15.79, P < 0.001). Conversely, CD 3+, CD 4+, and CD 4+/CD 8+ levels were lower in the study group compared to the control group ( t = 7.92, 8.41, 5.21, all P < 0.001). In the poor prognosis group, the levels of Ang-2 and IGF-1 were (335.16 ± 42.67) mg/L and (1406.18 ± 83.77) mg/L, respectively, both of which were significantly higher than those in the good prognosis group [(284.63 ± 36.19) mg/L, (434.91 ± 53.28) mg/L, t = 5.96, 64.1, both P < 0.001]. The CD 8+ levels in the poor prognosis group were also higher than those in the good prognosis group ( t = -10.27, P < 0.001), while CD 3+, CD 4+, and CD 4+/CD 8+ levels were lower in the poor prognosis group ( t = 5.31, 7.03, 3.15, all P < 0.001). Correlation analysis revealed that Ang-2 was negatively correlated with CD 3+, CD 4+, and CD 4+/CD 8+ levels ( r = -0.623, -0.578, -0.662). In contrast, Ang-2 was positively correlated with CD 8+ levels, a history of uterine fibroids, the number of fibroids, a history of miscarriage, and the duration of breastfeeding ( r = 0.593, 0.452, 0.446, 0.419, 0.422). IGF-1 levels were also negatively correlated with CD 3+, CD 4+, and CD 4+/CD 8+ levels ( r = -0.720, -0.751, -0.712), while positively correlated with CD 8+, a history of uterine fibroids, the number of fibroids, a history of miscarriage, and the duration of breastfeeding ( r = 0.631, 0.503, 0.444, 0.501, 0.451). Furthermore, multivariate logistic regression analysis indicated that a family history of uterine fibroids, the number of fibroids, a history of miscarriage, and the duration of breastfeeding were all significant risk factors affecting the prognosis of patients with uterine fibroids (all P < 0.05). Conclusions:Patients with uterine fibroids have higher levels of Ang-2, IGF-1 and CD 8+, while the levels of CD 3+, CD 4+, and CD 4+/CD 8+ are lower. Additionally, the expression levels of Ang-2 and IGF-1 are associated with the patients' immune factors and prognosis.

Objective To investigate the predictive capacity of the Triglyceride-Glucose(TyG)index and the Triglyceride-Glucose-Body Mass Index(TyG-BMI)for the development of hyperuricemia(HUA)in a health examination population,and to identify suitable indicators as risk assessment tools for HUA.Methods This study ultimately included 12 004 participants from a health examination cohort.According to SUA levels,the partici-pants were categorized into a normal group(n=9 952)and a hyperuricemia(HUA)group(n=2 052).The TyG index and TyG-BMI index were calculated,and participants were further stratified into four groups(Q1—Q4)based on the quartiles of these indices.Binary logistic regression analysis was performed to assess the association between TyG,TyG-BMI,and HUA.The predictive value of TyG,TyG-BMI,and their combination for HUA was evaluated using Receiver Operating Characteristic(ROC)curves and the Area Under the Curve(AUC).Subgroup analyses were carried out by gender and age.Results The TyG and TyG-BMI indices were significantly elevated in the HUA group compared to the normal group.The prevalence of HUA was markedly higher in the TyG-Q4 and TyG-BMI-Q4 groups than in the other three corresponding quartile groups.Binary logistic regression analysis revealed a positive association between TyG,TyG-BMI levels,and the risk of HUA.The AUC values for predicting HUA using TyG,TyG-BMI,and their combination were 0.700,0.747,and 0.822,respectively.Specifically,for males,the AUC values were 0.641,0.674,and 0.709,respectively,whereas for females,they were 0.742,0.776,and 0.829,respectively.Among individuals younger than 60 years old,the AUC values were 0.716,0.759,and 0.835,respectively,while for those aged 60 years or older,the values were 0.614,0.645,and 0.731,respectively.Conclusions TyG and TyG-BMI are significantly associated with the risk of HUA.Specifically,TyG-BMI demon-strates superior predictive performance compared to TyG alone.Moreover,the combination of TyG and TyG-BMI further improves predictive accuracy,particularly among female and middle-aged or younger populations.

OBJECTIVE To explore the implementation and standardized management of infection control core ele-ments in grass-roots medical institutions within county-level medical communities.METHODS From Mar.2024 to Apr.2024,the current status of implementation of infection control core elements in the grass-roots medical institu-tions within county-level medical communities was investigated by means of questionnaire survey and qualita-tive interview,and the implementation strategies were further explored.RESULTS The infection management or-ganizational system and functions of the two county-level medical institutions within the county medical communi-ties were completed,there is no independent hospital infection management department in the primary medical in-stitutions.The infection management personnel in the 16 grass-roots medical institutions were part-time person-nel,the personnel with the educational background below junior college accounted for 84.21％,the personnel with the professional background of nursing accounted for 100.00％,the personnel with less than 5 years of working experience accounted for 78.95％,none of them had an on-the-job training certificate.The monitoring programs of the county-level medical institutions within the county medical communities were completed,there was no infec-tion management monitoring information platform in the grass-roots medical institutions.The infection cases,hand hygiene,environmental health and occupational exposures were monitored by people.The grass-roots medi-cal institutions had the highest requirements for various professional trainings and increase of training contents of prevention and control of public health infectious diseases(100.00％).The county-level medical institutions had inadequate capabilities of professional examination of medical equipment replacement and construction of medi-cal architecture.CONCLUSION It is necessary for the country and local levels of governments to attach great importance to the implementation of the infection control core elements in the grass-roots medical institutions within the county-lev-el medical communities,establish the county-level regional information platform,formulate the corresponding surveil-lance indexes and homogenized management systems,complete the cultivation of talents,and offer financial support.

Objective To investigate the relationship between 418 C>G polymorphism of tissue metalloproteinase inhibitor-2(TIMP-2)gene and susceptibility to non-small cell lung cancer(NSCLC).Methods A total of 167 patients with NSCLC admitted to Suining Central Hospital from May 2021 to May 2023 were selected as the observation group,and 183 healthy subjects who underwent physical examination in the hospital during the same period were selected as the control group.The general data of the two groups were compared and the polymorphism of the TIMP-2 gene was analyzed.The genotype and allele frequency distribution of the polymorphic locus of the TIMP-2 gene were detected and compared between the two groups.Logistic regression was used to analyze the correlation between TIMP-2 gene 418 C>G site and NSCLC.Results The proportion of BMI≥24kg/m2 and smoking in the observation group were 67.07%and 61.08%,respectively,which were 44.26%and 40.44%in the control group,and the differences were statistically significant(χ2=18.356,14.881,all P<0.001).The variant GG homozygote produced three fragments of 230bp,51bp and 23bp in length,the wild-type CC homozygote produced 253bp and 51bp in length,and the heterozygous GC produced four pieces of 253bp,230bp,51bp and 23bp in length.The 51bp and 23bp fragments were not shown,and the TIMP-2 418 C>G gene identity was 100%.The genotype frequencies met the Hardy-Weinberg genetic equilibrium(P>0.05).The frequencies of CC,GC and GG of the TIMP-2 genotype in the observation group were 10.18%,41.92%and 47.90%,respectively,and those in the control group were 4.37%,37.70%and 57.92%,respectively,and the difference was statistically significant(χ2=6.163,P=0.046).The frequencies of the C and G alleles of TIMP-2 in the observation group were 31.14%and 68.86%,respectively,and those in the control group were 23.22%and 76.78%,respectively,and the difference was statistically significant(χ2=5.549,P=0.018).Compared with the control group Logistic regression analysis showed that genotype carrying the C allele significantly increased the risk of NSCLC(OR=2.669,95%CI:1.478～2.936,P<0.01).Compared with the GG+GC group,the proportion of patients with CC genotype who had poor chromosome karyotype prognosis,the proportion of high-risk group in the International Prognostic Scoring System(IPSS)risk group and the levels of CRP and PCT were increased,and the differences were statistically significant(t=3.633～11.249,all P<0.001).Absolute neutrophil count(ANC),Haemoglobin(HGB)and Platelet(PLT)decreased,and the differences were statistically significant(t=4.760,2.015,2.212,all P<0.05).Multivariate COX regression analysis showed that CC genotype,chromosome karyotype,IPSS risk group,ANC,HGB,PLT,CRP,and PCT were risk factors for poor prognosis in NSCLC(Wald χ2=3.072～17.611,all P<0.05).The results of the multifactor dimensionality reduction(MDR)method showed that the interaction combination of abnormal ANC,HGB,PLT,CRP,and PCT levels and TIMP-2 gene polymorphism was 2.650 times higher than that of NSCLC.Conclusion The CC genotype and C allele of the 418 C>G locus of TIMP-2 gene are significantly associated with the risk of NSCLC and are independent risk factors for NSCLC.

Objective To Investigate the efficacy of modified electroconvulsive therapy(MECT)in patients with schizophrenia across different genders.Methods From May 2018 to August 2022,481 patients with schizophrenia were recruited from three psychiatric hospitals in Luzhou,Zigong,and Yibin.According to gender grouping,both groups received adjunctive MECT treatment for two consecutive weeks for a total of six treatments.The differences in positive and negative syndrome scale(PANSS)scores before and after treatment,UKU adverse reaction rating scale(UKU),and gastrointestinal symptom rating scale(GSRS)scores were compared between the two groups.Results After quality control,463 cases were followed up for analysis including 246 males and 217 females.Compared with pre-treatment,the total PANSS score and scores on each subscale were significantly reduced in both genders after treatment(P<0.001).When comparing the reduction rates between the groups,the male patients showed a higher reduction rate in negative symptoms than the female patients(31.24%±30.24%vs.25.80%±33.96%,P<0.05).However,there were no significant differences between the two groups in the reduction rates of the total score,positive symptoms,and general psychopathology(P>0.05).The comparison of adverse reactions showed that the frequency of other types of adverse reactions was higher in female patients than in male patients(47.47%vs.37.80%,P<0.05).However,no significant differences were observed in the adverse reactions related to the mental,neurological,autonomic nervous system,and gastrointestinal systems(P>0.05).Correlation analysis revealed that the reduction rate of the PANSS total score was positively correlated with smoking history(r=0.135,P=0.034)and alcohol history(r=0.160,P=0.012)in male patients,while the reduction rate of the PANSS total score was negatively correlated with the disease duration(r=-0.210,P=0.002)and positively correlated with the age of onset(r=0.145,P=0.032)in female patients.Conclusion MECT is significantly effective for both male and female patients with schizophrenia.Compared to female patients,MECT shows a more pronounced effect on negative symptoms in male patients.Additionally,the factors related to the efficacy of MECT differ between genders,indicating that it is necessary to consider the clinical characteristics of patients comprehensively when selecting an MECT treatment plan.

Objective To understand the current status of traditional Chinese medicine(TCM)systematic reviews/Meta-analysis over the past 10 years.Methods Cochrane Database of Systematic Reviews,PubMed,Web of Knowledge,CNKI,SinoMed,WanFang Data,VIP databases,as well as the Cochrane Register and PROSPERO registration platform were searched to collect TCM-related systematic reviews/Meta-analysis published between January 2015 and December 2024.Literature was screened,and standardization of institutions,countries,and journals was performed.Data cleaning was conducted,and trends in publication years,high-frequency diseases,journals,institutions,and highly cited papers were analyzed.Results A total of 11,174 papers were included,involving approximately 56,656 authors from 1,422 institutions across 44 countries,covering 1,300 journals and 1,070 diseases.The top five institutions in terms of publications were Beijing University of Chinese Medicine(954 papers),Guangzhou University of Chinese Medicine(928 papers),China Academy of Chinese Medical Sciences(537 papers),Tianjin University of Chinese Medicine(460 papers),and Chengdu University of Chinese Medicine(393 papers).Foreign institutions with the highest publication volumes were concentrated in South Korea,Iran,and Australia.The most frequently published Chinese journal was Zhongyi Clinical Research with 332 papers,while the most published English journal was Evidence-Based Complementary and Alternative Medicine with 311 papers.There were 282 single-author papers involving 271 authors,and the most cited paper was referenced 323 times,The three most frequently studied diseases were diabetes(267 papers,2.39％),angina pectoris(214 papers,1.92％),and osteoarthritis(210 papers,1.88％).Non-pharmacological interventions such as acupuncture(1,265 papers,11.32％),auricular therapy(101 papers,0.90％),and Tai Chi(98 papers,0.88％)were most frequently reported.In pharmacological interventions,studies on Tripterygium wilfordii tablets(76 papers,0.68％)and Danhong injection(54 papers,0.48％)were more common.Conclusion The systematic reviews/Meta-analysis method is widely used in the field of TCM,and the field continues to grow.Active academic teams,institutions,and journals have emerged.Over the past decade,there has been a considerable body of evidence in Chinese systematic reviews on TCM for chronic diseases such as diabetes,angina pectoris,and osteoarthritis.In English-language studies,non-pharmacological therapies like acupuncture have been more widely reported,and some high-impact studies have emerged.However,challenges remain,such as issues with research transparency and methodological standardization.Future efforts should focus on establishing transparent systems and quality control mechanisms to further enhance the reliability,accuracy,and dissemination of TCM evidence-based research.
