Objective : To compare the antiviral efficacy and renal safety of nucleoside analogs(NAs) monotherapy versus combination therapy in hepatitis B e antigen(HBeAg)-positive chronic hepatitis B(CHB) patients with high viral load. Methods : This study enrolled a total of 353 treatment-naïve HBeAg-positive chronic hepatitis B (CHB) patients with high viral load , the treatment regimen was divided into 5 groups , consisting of 4 monotherapy groups and 1 combination therapy group as follows : 88 cases in the Entecavir (ETV) group , 135 cases in the Teno- fovir Disoproxil Fumarate (TDF) group , 34 cases in the Tenofovir Alafenamide Fumarate (TAF) group , 25 cases in the Tenofovir Amibufenamide (TMF) group , and 71 cases in the ETV combined with TDF (ETV + TDF) group . A retrospective cohort study design was adopted to analyze HBV DNA levels , serological indicators ( HBsAg and HBeAg levels) , renal function indicators ( serum Scr levels , eGFR) at 24 and 48 weeks of treatment across various groups , as well as the HBsAg clearance rates , HBeAg seroconversion rates and HBV DNA suppression rates (HBV DNA < 20 IU/ml) at 48 weeks across the groups . Multivariate logistic regression analysis was conducted to identify the influencing factors for HBV DNA suppression . Results : At 24 weeks , the HBV DNA level in the ETV + TDF selected . Key miRNAs included hsa-let-7b-5p , hsa-let-7c-5p , hsa-let-7b-3p _ 1ss22CT , and hsa-miR-199b-5p , with BACH1 and IFNAR1 identified as their shared target genes . GO analysis revealed that the enriched target genes were primarily involved in protein binding , metal ion binding , transferase activity , DNA binding , transcriptional regulation by RNA polymerase Ⅱ , and nucleotide binding. KEGG pathway analysis indicated that the target genes were mainly associated with metabolic pathways , cancer-related pathways , the PI3K-Akt signaling pathway , and the Rap1 signaling pathway . Conclusion Differential expression of miRNAs in amniotic fluid exosomes was ob- served between DS fetuses and those with normal karyotypes . Combined analysis with placental miRNAs revealed hsa-miR-199b-5p as a common differentially expressed miRNA in both DS amniotic fluid and placenta. It is hypoth- esized that BACH1 and IFNAR1 , shared target genes of hsa-miR-199b-5p , hsa-let-7b-5p , hsa-let-7c-5p , and hsa- let-7b-3p_1ss22CT , may play a role in the pathogenesis of DS .

OBJECTIVE: To observe the clinical efficacy of electroacupuncture combined with ear tip bloodletting for insomnia with phlegm-fire disturbing heart.

Background Air pollution exposure has a significant impact on maternal and child health. However, the research on the association between ambient ozone (O₃) exposure during pregnancy and the risk of premature birth in newborns is limited, and the conclusions are inconsistent. Objective To investigate the association of ambient O₃ exposure during pregnancy with the risk of preterm birth in Guangdong Province. Methods Data of pregnant women in Guangzhou from 2013 to 2019 and Foshan from 2018 to 2023 were collected, and O₃ concentrations during different trimesters were assessed according to maternal residential addresses. Bilinear interpolation was used to evaluate the concentrations of air pollution. A cohort study design was adopted in our study. Restricted cubic spline curves were used to evaluate the exposure-response relationship between O₃ exposure and preterm birth risk and explore potential exposure threshold of O₃. Logistic regression models were used to evaluate the association of O₃ exposure with preterm birth. Results A total of 702 924 pregnant women were included in this study, of whom 43 051 (6.12%) were preterm. The average O₃ exposure concentrations of pregnant women during the first, second, third, and whole trimesters were 95.51, 97.51, 100.60, and 97.87 μg·m⁻³, respectively. We observed J-shaped associations between O₃ exposure and preterm birth risk during the second, third, and whole trimesters of pregnancy using restricted cubic spline curves. This study found that there were threshold concentrations between O₃ exposure and preterm birth risk during different gestational periods, and the threshold concentrations in the first, second, third, and whole trimesters were 112.32, 99.83, 111.74, and 112.46 μg·m⁻³, respectively. During the second, third, and whole trimesters of pregnancy, after adjusting for maternal age, baby sex, pre-pregnancy body mass index, mode of delivery, baby birth weight, gestational diabetes, and gestational hypertension, the odds ratios (OR) of preterm birth were 1.02 (95%CI: 1.01, 1.04), 1.02 (95%CI: 1.00, 1.03), and 1.17 (95%CI: 1.13, 1.21) for each 10 μg·m⁻³ increase in O₃ concentration above the O₃ threshold. No significant association was found between O₃ exposure and the risk of preterm birth during the first trimester. Conclusion There is a nonlinear association between the risk of preterm birth and O₃ exposure during pregnancy, and higher concentrations of O₃ exposure during pregnancy are associated with the risk of preterm birth. Above the O₃ threshold concentration during pregnancy, especially during the second, third, and whole trimesters, the risk of preterm birth elevates with the increase of O₃ exposure concentrations.

Objective:To analyze the epidemiological and clinical features of infectious diseases of the central nervous system (CNS).Methods:A cross-sectional study and analysis were conducted to summarize the epidemiological and clinical characteristics of 9 918 patients with CNS infectious diseases, who were diagnosed and treated at 29 hospitals across China from January 1, 2001 to December 31, 2020. Data collected included demographic data, clinical manifestations, health economic indicators, and prognostic outcomes.Results:Among the 9 918 collected cases of CNS infectious diseases, 5 559 were male (56.0%) and 4 359 were female (44.0%), with an onset age of 38 (25, 53) years. Education level: slightly more junior high school education (2 651 cases, 26.7%), and less elementary school education and below (2 181 cases, 22.0%) were found. Occupational distribution: farmers were found predominant (3 215 cases, 32.4%), followed by workers (1 826 cases, 18.4%) and students (1 633 cases, 16.5%). Clinical manifestations: headache (6 074 cases, 61.2%), fever (5 869 cases, 59.2%) and positive meningeal irritation signs (2 273 cases, 22.9%) were the 3 most common clinical manifestations, followed by nausea and (or) vomiting (2 095 cases, 21.1%), impaired consciousness (2 077 cases, 20.9%), psychiatric symptom (1 866 cases, 18.8%) and epilepsy (1 627 cases, 16.4%), etc., and cranial nerve involvement was found in 669 cases (6.7%). Major pathogens included viruses in 6 814 cases (68.7%), Mycobacterium tuberculosis in 1 677 cases (16.9%), common bacteria in 864 cases (8.7%), fungi in 254 cases (2.6%), spirochetes of syphilis in 183 cases (1.8%), parasites in 121 cases (1.2%), and rickettsiae in 5 cases (0.1%). Urban-rural distribution: slightly more cases were found in the countryside (5 418 cases, 54.6%) than in the towns (4 500 cases, 45.4%). Distribution of onset by season: 2 412 cases (24.3%) fell ill in spring, 2 835 cases (28.6%) in summer, 2 187 cases (22.1%) in fall, and 2 484 cases (25.0%) in winter. Health economics: the duration of hospitalization was 15 (8, 27) days, and the cost of hospitalization was 1.53 (0.91, 3.02)×10 000 yuan. Prognosis: 9 531 cases (96.1%) were cured or improved, and 92 cases (0.9%) died. Conclusions:The pathogens responsible for CNS infectious diseases are predominantly viruses. Although the incidence is slightly higher during the summer months, the overall seasonal pattern is not particularly pronounced. These infections are more commonly observed in young and middle-aged males and present with a diverse range of clinical manifestations, contributing to a significant disease burden.

Objective:To investigate effect of Gehua Jiecheng Decoction on IL-6/JAK2/STAT3 signaling pathway in colon tissue of ulcerative colitis with"inflammatory to cancer transformation"(UC-UCAC)mice of spleen deficiency and damp-heat type.Methods:Ten from 80 SPF C57BL/6 male mice were randomly selected as blank group and other 70 mice were selected as model group.After establishment of spleen deficient damp-heat model,mice were randomly divided into model group(1st,2nd and 3rd cycle),Gehua Jiecheng Decoction high,medium and low doses groups and mesalazine group,with 10 pieces per group.UC-UCAC transformation model was further established with azo methane oxide solution(AOM)/sodium glucan sulfate(DSS).Each group was treated with corresponding drugs for 4 weeks.General state of mice was observed.Score of disease activity index(DAI)was calculated.HE staining was used to observe colonic mucosa pathology of mice.EGFR,IL-6,JAK2,STAT3 and p-STAT3 proteins and genes expressions in mice colon tissues were detected by Western blot,IHC and RT-qPCR,respectively.Results:Compared with blank group,mice in model group(3rd cycle)were generally in a worse state,colon mucosal tissue was cancerous,DAI score,target proteins and genes expressions were significantly increased(P<0.01).Compared with model group(3rd cycle),general state of mice in all treatment groups were restored and colonic tissues pathology were improved to some extent.Target proteins and genes expressions in other treatment groups were significantly decreased except for Gehua Jiecheng Decoction low-dose group(P<0.01).Conclusion:Gehua Jiecheng Decoction may destroy tumor inflammatory microenvironment,repair damaged colonic mucosa tissue,delay inflamma-tion-cancer transformation process and prevent UCAC by inhibiting activation of IL-6/JAK2/STAT3 signaling pathway.

Objective:To clone the Helicobacter pylori(Hp)hp0169 gene and conduct the crystallographic study,and to clarify its secondary and tertiary structures.Methods:The hp0169 gene and its encoded protein sequence of the Hp NCTC26695 strain were retrieved from the UniProt database.Bioinformatics method was used to analyze the physicochemical properties of the Hp recombinant protease(HpPrtC)protein;SOPMA and DNAStrar softwares were used to predict the secondary structure characteristics of HpPrtC protein;SWISS-MODEL software was used to construct the tertiary structure of the HpPrtC protein;IEDB and ABCpred softwares were used to predict the antigenic epitopes of the B lymphocytes HpPrtC protein;SYFPEITMI website was used to predict the antigenic epitopes of the T lymphocytes of HpPrtC protein;the expert pool(EP)and random forest(RF)algorithms were used to predict the crystallizability of the HpPrtC protein;the HpPrtC recombinant protein was expressed in the prokaryotic system;the HpPrtC recombinant protein was purified by Ni2+affinity chromatography and size-exclusion chromatography;the crystallization conditions for HpPrtC were screened by crystallization kit.Results:The hp0169 gene contained 1 269 base pairs and encoded the protein of 422 amino acids,the theoretical isoelectric point was 7.64 and the relative molecular weight was 47 300.HpPrtC was a hydrophilic and soluble protein.The number of amino acids of alpha helices of HpPrtC accounted for 35.78%,beta sheets 18.72%,beta turns 6.87%,and random coils 38.63%.The antigen epitope analysis results showed that HpPrtC contained five dominant linear epitopes of B lymphocytes,three conformational epitopes,and multiple potential dominant epitopes of T lymphocytes.The homology modeling results showed that HpPrtC formed a dimer,and each monomer displayed a barrel structure surrounded by β sheets,alpha helices,and random coils.HpPrtC was predicted to have moderate crystallizability without signal peptides and transmembrane helices.Small clustered needle-like crystals of HpPrtC were obtained under the conditions of 0.2 mol·L-1 magnesium chloride,0.1 mol·L-1 tris(hydroxymethyl)amino methane(Tris),3.4 mol·L-1 hexanediol,and pH=8.5.Conclusion:HpPrtC is a hydrophilic protein that forms a dimeric structure and crystallizes into small clustered needle-like crystals under suitable conditions.HpPrtC contains dominant antigenic epitopes of the T lymphocytes and B lymphocytes and can serve as an antigen for the design of Hp vaccines to establish the multivalent fusion vaccines or multi-epitope vaccines;the results provide an experimental basis for the prevention and control of Hp.

Objective To observe the effect of electroacupuncture(EA)on the immune balance between helper T cell 17(Th 17)/regulatory T cells(Treg)in the spleens of mice with dextran sulfate sodium(DSS)-induced ulcerative colitis(UC)by modulating the interleukin-6(IL-6)/signal transducer and activator of transcription 3(STAT3)signaling pathway,and to explore part of the mechanism of EA on treating UC.Methods Male C57BL/6N mice were randomly divided into UC model group,EA group,and sham acupuncture(SA)group,with 10 mice in each group,and 10 mice in the blank control group.After establishing the UC model mice by DSS free-drinking method,bilateral"Tianshu(ST25)"and"Shangjiuxu(ST37)"were selected for EA or SA treatment for 20 min each time,with a total of 10 times.The general condition and disease activity index(DAI)of the mice in each group were observed,the pathological changes of colon tissue were observed by HE staining,the levels of IL-6,IL-10 and IL-17 in serum were detected by ELISA,and the protein expression levels of IL-6,STAT3,retinoic acid-related orphan receptor gamma t(RORγt)and Forkhead box protein P3(FoxP3)were detected by Western blot in the colon tissue.Results Compared with the blank group,mice in the model group had significantly higher DAI scores(P＜0.01),with colonic mucosal rupture and massive inflammatory cell infiltration.Significant increases were detected in serum IL-6 and IL-17 levels(P＜0.01),with significant reductions in IL-10 levels(P＜0.01).Significant increases were detected in the expression of IL-6,STAT3,and RORγt in colonic tissues(P＜0.01),with the decreased expression of FoxP3(P＜0.05).The percentage of Th17 cells in the spleen was increased and the percentage of Treg cells was decreased(P＜0.05).Compared with the model group,mice in the EA group had lower DAI scores(P＜0.05),with reduced colonic injury,decreased inflammatory infiltration.Decreased serum IL-6 and IL-17 levels,with increased IL-10 levels(P＜0.05)were detected.Significantly lower IL-6,STAT3,and RORγt expression in the colonic tissues(P＜0.01),and increased FoxP3 expression(P＜0.05)were detected,as well as the decreased percentage of Th17 cells and increased percentage of Treg cells in spleen(P＜0.05).However,the colonic injury of mice in the SA group did not show any improvement,and no statistical difference was observed in these indexes compared with the model group.Conclusion EA may exert a therapeutic effect on UC by down-regulating the IL-6/STAT3 signaling pathway and promoting the restoration of immune balance by Th17/Treg,thereby diminishing intestinal inflammation in UC mice.
