Objective Based on the Preferred Reporting Items for Systematic reviews and Meta-Analyses(PRISMA)guidelines,to obtain precise and reliable comprehensive effect conclusions by quantitatively combining pharmacodynamic results from animal experiments investigating Astragali Radix(single-entity Astragali Radix preparation)or its ingredients for treatment of acute pancreatitis(AP)in literature reports through meta-analysis.Methods Databases including China National Knowledge Infrastructure(CNKI),VIP Database for Chinese Technical Periodicals(VIP),Wanfang Data Knowledge Service Platform,China Biomedical Literature Database(CBMdisc),PubMed,and Web of Science(WOS)were searched from inception to March 2025 for animal studies related to Astragali Radix(single-entity Astragali Radix preparation)or its ingredients for AP treatment.Risk of bias for included studies was assessed with SYRCLE tool.Heterogeneity among studies was evaluated according to Cochrane Handbook using Cochrane's Qtest and/2statistic.Sensitivity analysis was performed using the leave-one-out method,and publication bias risk was detected using Egger's test.Results A total of 297 articles were retrieved,and after screening and evaluation,19 animal studies were finally included for meta-analysis.These 19 publications cover SD rats,as well as three breeds of mice:C57BL/6 mice,BALB/c mice,and Kunming mice.SYRCLE scores ranged from 3 to 4.The results of the sensitivity analysis showed that no study significantly affected the heterogeneity index.The results of Egger's test showed a significant publication bias with P＜0.05.Cochrane's Qtest and I2statistic indicated substantial heterogeneity among studies.Meta-analysis results of 19 animal studies showed that single-entity Astragali Radix preparation(Astragali Radix injection)could reduce serum amylase(AMY)levels,an AP-specific indicator.The Astragali Radix ingredients could decrease both AMY and lipase(LPS)levels.Astragali Radix injection or its ingredients could reduce serum levels of tumor necrosis factor-α(TNF-α),interleukin(IL)-6,and IL-1 β,while increasing IL-10 levels;could increase serum levels of superoxide dismutase(SOD)and glutathione peroxidase(GSH-Px),and decrease malondialdehyde(MDA)levels.High-dose groups of Astragali Radix injection or Astragali Radix ingredients were more effective than low-dose groups in reducing AMY,TNF-α,and IL-6 levels and increasing SOD levels,but dosage effect on MDA levels was not demonstrated.Conclusion Evidence-based analysis of animal experiment results shows that in various animal models including SD rats,C57BL/6 mice,BALB/c mice,and Kunming mice,Astragali Radix injection or its ingredients can effectively reduce expression or secretion levels of AP-specific indicators(AMY and LPS).The mechanisms may be related to some inflammatory mediators,including reducing TNF-α,IL-6,and IL-1 β levels and increasing IL-10 levels;They may also intervene in oxidative/antioxidative equilibrium,such as increasing SOD and GSH-Px levels and reducing MDA levels.Except for MDA,dose-response relationships are shown for reducing AMY,TNF-α,and IL-6 levels and increasing SOD levels with Astragali Radix injection or its ingredients.However,due to high heterogeneity,potential publication bias risk,and species differences between animal models and human diseases in existing studies,further high-quality clinical trials or animal experiments are still needed in the future.

Objective:To investigate the distribution of CGG repeat numbers in the FMR1 gene among reproductive-age women in China, providing data reference for carrier screening and genetic counseling of Fragile X syndrome. Methods:This cross-sectional study recruited 16 610 reproductive-age women from 12 medical institutions between July 2022 and October 2023. Peripheral venous blood samples (3 mL) were collected, and genomic DNA was extracted. The number of CGG repeats in the FMR1 gene was determined using the triplet-primed polymerase chain reaction (TP-PCR) combined with capillary electrophoresis technology. Statistical analyses were performed to assess the prevalence and distribution of CGG repeat expansions. Results:Among 16 610 women of childbearing age, 5 684 (34.220%) women had the same number of CGG repeats in the two alleles of FMR1 gene, and 10 926 (65.780%) women had different numbers of repeats in the two alleles. Among the 33 220 FMR1 alleles in 16 610 women of reproductive age, the most common CGG repeat numbers were 29 [48.645% (16 160/33 220)] and 30 [26.276% (8 729/33 220)], while the most frequent CGG genotype was CGG 29/29 [24.726% (4 107/16 610)]. The CGG repeat numbers of FMR1 gene were normal in 16 498 women (99.326%). Among the 112 women (0.674%) with CGG repeat abnormities, 96 (0.578%) women were classified as intermediate carriers, 15 (0.090%) as premutation carriers, and 1 (0.006%) as a full mutation carrier, whose CGG genotype was (36, >200). Conclusion:In the general reproductive-age female population in China, the normal CGG repeat numbers of the FMR1 gene account for 99.326%, while the intermediate carrier rate is 0.578%, and the combined carrier rate of the premutation and full mutation types is 0.096%.

Objective:To explore the predictive value of prognostic nutritional index (PNI) combined with serum peroxiredoxin 3 (PRX3) level for the prognosis of patients with advanced high-grade serous ovarian cancer (HGSOC) .Methods:A total of 103 patients with advanced HGSOC admitted to Affiliated Hospital of Jining Medical University from Jan. 2020 to Dec. 2022 were retrospectively selected and included in the study. Serum albumin (Alb), PRX3 levels and peripheral blood lymphocyte count (LY) levels were measured. The patients were followed up for 2 years, and they were divided into good prognosis group (70 cases) and poor prognosis group (33 cases). Multivariate stepwise Logistic regression analysis was used to analyze the prognostic factors. The receiver operating characteristic (ROC) curve was used to analyze the predictive efficacy of PNI combined with PRX3 on prognosis.Results:The age, proportion of postoperative residual lesions, proportion of lymph node metastasis, proportion of stage Ⅲ, and PRX3 level in the poor prognosis group were higher than those in the good prognosis group, and the PNI level was lower than that in the good prognosis group ( P<0.05). Multivariate Logistic regression analysis showed that postoperative residual lesions ( OR=2.731, 95% CI: 1.562-4.774), clinical stage ( OR=3.526, 95% CI: 1.503-8.271), PNI level ( OR=0.148, 95% CI: 1.503-8.271) 0.057-0.387) and PRX3 level ( OR=4.011, 95% CI: 1.972-8.154) were independent influencing factors for the prognosis of patients ( P<0.05). ROC curve analysis showed that the area under the curve (AUC) of PNI, PRX3 and their combination for predicting the prognosis of advanced HGSOC patients were 0.807, 0.781 and 0.874, respectively ( P<0.05). The survival curve of patients with high PNI and PRX3 levels was different from that of patients with low PNI and PRX3 levels ( P<0.05) . Conclusion:PNI and PRX3 are independent prognostic factors for advanced HGSOC patients, and the combination of PNI and PRX3 has a better prognostic value in patients with advanced HGSOC.

OBJECTIVE To analyze the clinical characteristics and the correlation between laboratory indicators and prognosis of severe Mycoplasma pneumoniae pneumonia(SMPP)in children.METHODS A total of 85 children with SMPP admitted to Anhui Provincial Children's Hospital from Nov.2021 to May 2024 were selected as the study subjects.Based on clinical typing at admission,they were divided into a high-risk group(n=59)and a low-risk group(n=26).The clinical manifestations,laboratory indicators and outcomes at 28 days of treatment were compared between the two groups.RESULTS The duration of fever and cough before admission in the high-risk group was(7.17±1.09)days and(6.79±1.25)days,respectively,which was longer than that in the low-risk group(P＜0.05).There were no statistically significant differences in pulmonary auscultation(wheezing rales,moist rales)and extrapulmonary complications between the two groups.The levels of C-reactive protein(CRP),serum amyloid A(SAA),platelets(PLT),fibrinogen(FIB),D-dimer(DD)and N-terminal pro-brain natriuretic peptide(NT-proBNP)in the high-risk group were(11.62±1.45)mg/L,(226.88±36.83)mg/L,(3 18.57±39.82)×109/L,(4.28±0.74)g/L,(0.81±0.12)μg/ml and(2 295.48±413.75)pg/ml,respectively,all of which were higher than those in the low-risk group(P＜0.05).Within 28 days after treatment of children in both groups,one patient in the high-risk group died.CONCLUSIONS Compared with children with SMPP in the low-risk group,those in the high-risk group have a higher risk of prognostic mor-tality,suggesting a correlation between the children's blood CRP,SAA,PLT,FIB,DD and NT-proBNP levels and the prognosis of children with SMPP.

Objective To establish an animal model of hand,foot,and mouth disease(HFMD)in Syrian hamsters coinfected with coxsackievirus A6(CVA6)and coxsackievirus B1(CVB1).Methods 42 Syrian hamsters were divided into a CVA6 infection group,CVB1 infection group,CVA6 and CVB1 coinfection group and control group.A HFMD model was established by nasal instillation of virus solution and phosphate-buffered saline.Clinical and physiological indicators and detoxification status were monitored and recorded for 15 d,and animals were selected on day 7(D7)after infection for histopathology and viral antigen and nucleic acid testing.Results Hamsters in the single-infection and coinfection groups showed clinical symptoms similar to human HFMD.White blood cell,neutrophil,and lymphocyte result were characteristic of viral infection.Both viral nucleic acids were detected in throat swabs,feces,blood,and tissues and both viruses were isolated from fecal samples.Pathological damage and positive co-localization of CVA6 and CVB1 viral antigen proteins and nucleic acids were found in brain and other tissues.Conclusions Nasal instillation of a CVA6 and CVB1 mixture can successfully coinfect Syrian hamsters,replicate herpes infection similar to human HFMD,and cause pathological viral myocarditis and encephalitis damage.The result showed that the coinfection group was more seriously affected than the single-infection group,with worse clinical symptoms,increased viral replication,and obvious tissue pathological damage.This study provides a reference for further basic and clinical research into human enterovirus coinfection.
