The medicinal materials of Bawei Chenxiang Pills(BCPs) were extracted via three methods: reflux extraction by water, reflux extraction by 70% ethanol, and extraction by pure water following reflux extraction by 70% ethanol, yielding three extracts of ST, CT, and CST. The efficacy of ST(760 mg·kg~(-1)), CT(620 mg·kg~(-1)), and CST(1 040 mg·kg~(-1)) were evaluated by acute myocardial ischemia(AMI) and p-chlorophenylalanine(PCPA)-induced insomnia in mice, respectively. Western blot was further utilized to investigate their hypnosis mechanisms. The main chemical components of different extracts were identified by the UPLC-Q-Exactive-MS technique. The results showed that CT and CST significantly increased the ejection fraction(EF) and fractional shortening(FS) of myocardial infarction mice, reduced left ventricular internal dimension at end-diastole(LVIDd) and left ventricular internal dimension at end-systole(LVIDs). In contrast, ST did not exhibit significant effects on these parameters. In the insomnia model, CT significantly reduced sleep latency and prolonged sleep duration, whereas ST only prolonged sleep duration without shortening sleep latency. CST showed no significant effects on either sleep latency or sleep duration. Additionally, both CT and ST upregulated glutamic acid decarboxylase 67(GAD67) protein expression in brain tissue. A total of 15 main chemical components were identified from CT, including 2-(2-phenylethyl) chromone and 6-methoxy-2-(2-phenylethyl) chromone. Six chemical components including chebulidic acid were identified from ST. The results suggested that chromones and terpenes were potential anti-myocardial ischemia drugs of BCPs, and tannin and phenolic acids were potential hypnosis drugs. This study enriches the pharmacological and chemical research of BCPs, providing a basis and reference for their secondary development, quality standard improvement, and clinical application.

Objective:To investigate the relationship between adiponectin (ADIPOQ) gene polymorphism and postpartum type 2 diabetes mellitus (T2DM) in pregnant women with gestational diabetes mellitus (GDM).Methods:A retrospective study was conducted on 236 GDM postpartum women admitted to the Affiliated Hospital of Jining Medical College from June 2020 to June 2021 as observation subjects. They were divided into a T2DM group and a non T2DM group based on the occurrence of T2DM after delivery. The clinical data of the two groups were compared. The double deoxygenation end termination method was used to detect the single nucleotide polymorphism (SNP) of the ADIPOQ gene, and the four loci rs17366568, rs822395, rs1501299, and rs2241766 were classified. The relationship between ADIPOQ genotype polymorphism and postpartum T2DM was analyzed using a logistic regression model.Results:The G allele carrying the rs2241766 locus in ADIPOQ gene was negatively correlated with the occurrence of T2DM ( OR=0.71, 0.68, P<0.05). Compared with T2DM patients with TT genotype, the GT+ GG genotype at the rs2241766 locus had a lower risk of occurrence for gestational age ≥2 and HbA 1c>85%. Similarly, T2DM patients with pre pregnancy body mass index (BMI)>25 kg/m 2 were more likely to be carriers of the rs2241766 TT genotype ( P=0.026). The (GT+ TT) genotype carrying the T allele at the rs1501299 locus was a protective factor for gestational age and HbA 1c in T2DM patients. Conclusions:The rs2241766 and rs1501299 polymorphisms of the ADIPOQ gene are associated with susceptibility to postpartum T2DM in GDM women. Individuals with rs2241766 and rs1501299 mutant genotypes belong to the high-risk population for T2DM.

Aim To explore the mechanism of Guso-ngYigu decoction(GSYG)in the treatment of postm-enopausal osteoporosis(PMOP)based on the gut mi-crobiota.Methods Sixty SPF grade SD rats were ran-domly divided into Control group(Control),Model group(Model),GSYG low-dose group(GSYG-L,1.25 g·kg-1),medium-dose group(GSYG-M,2.5 g·kg-1)and high-dose group(GSYG-H,5 g·kg-1)and alendronate group(Al,0.89 mg·kg-1),with 10 rats in each group.The changes of bone histomorpholo-gy were detected by HE staining and the changes of fe-mur tissue structure were observed by micro-CT.The fecal samples from the colon of Control group,Model group,GSYG-H group were taken to extract the DNA of fecal samples.The Illumina Miseq platform was used to carry out high-throughput sequencing.Results Compared with the Control group,bone trabecula in the Model group was sparse,BV/TV,Tb.Th,Tb.N and BMD decreased(P＜0.01),while SMI and Tb.Sp increased(P＜0.01);compared with the Model group,the number of bone trabeculae in GSYG-L,GSYG-M,GSYG-H group and Al group increased,the bone microstructure was improved,BV/TV,Tb.Th,Tb.N and BMD increased significantly(P＜0.05),and SMI and Tb.Sp increased(P＜0.05).Sequencing results of gut microbiota showed that,compared with the Control group,the gut microbiota diversity of Mod-el group decreased,the flora abundance of Firmicutes decreased,while the Bacteroidetes abundance in-creased.Compared with the Model group,the Firmi-cutes abundance increased and Bacteroidetes abundance decreased in GSYG-H group.Conclusions GSYG can improve bone microstructure and increase bone mineral density,and its mechanism may be related to increasing the diversity of gut microbiota and regulating the structure of gut microbiota.

Objective:To explore the value of REG3α,sST2 and TNFR1 in peripheral blood for risk stratification and prognostic evaluation of acute graft-versus-host disease(aGVHD)after allogeneic hematopoietic stem cell transplantation(allo-HSCT)in children.Methods:From January 2020 to March 2022,70 children with aGVHD after allo-HSCT in the First Affiliated Hospital of Zhengzhou University were selected as the research objects,of which 50 cases were mild aGVHD(grade Ⅰ-Ⅱ)and 20 cases were severe aGVHD(grade Ⅲ-Ⅳ).30 healthy children who underwent physical examinations in our hospital during the same period were selected as the control group.Luminex platform was used to detect the protein expression levels of REG3α,sST2 and TNFR1 during aGVHD occurrence,and the differences between the three groups were analyzed by one-way ANOVA.According to the outcome of aGVHD treatment within 28 days,the patients were divided into a good prognosis group of 58 cases and a poor prognosis group of 12 cases.The ROC curve was used to analyze the value of REG3α,sST2 and TNFR1 in predicting the prognosis of children with aGVHD.Results:The peripheral blood levels of REG3α,sST2 and TNFR1 in the mild aGVHD and severe aGVHD groups were significantly higher than those in the control group(P＜0.05),and those in the severe aGVHD group were significantly higher than those in the mild aGVHD group(P＜0.05).Compared with the good prognosis group,the peripheral blood levels of REG3α,sST2 and TNFR1 in the poor prognosis group were significantly higher(t=9.27,3.33,2.97;P＜0.01).ROC curve analysis showed that the area under the curve(AUC),sensitivity and specificity of the combined detection of REG3α,sST2 and TNFR1 in predicting the prognosis of children with aGVHD were higher than those of the above indicators detected alone or in pairs.Conclusion:The expression levels of REG3α,sST2 and TNFR1 were related to the severity of aGVHD.The combination of REG3α,sST2 and TNFR1 has a high clinical value in predicting the prognosis of children with aGVHD,which is expected to provide a reliable reference for clinical evaluation of the prognosis of children with aGVHD.

Purpose: We aimed to comprehensively analyze the immune cell and stromal components of tumor microenvironment at the single-cell level and identify tumor heterogeneity among the major top-derived oncogene mutations in non-small cell lung cancer (NSCLC) using single-cell RNA sequencing (scRNA-seq) data. Materials and Methods: The scRNA-seq dataset utilized in this study comprised 64369 primary tumor tissue cells from 21 NSCLC patients, focusing on mutations in EGFR, ALK, BRAF, KRAS, TP53, and the wild-type. Results: Tumor immune microenvironment (TIM) analysis revealed differential immune responses across NSCLC mutation subtypes. TIM analysis revealed different immune responses across the mutation subtypes. Two mutation clusters emerged: KRAS, TP53, and EGFR+TP53 mutations (MC1); and EGFR, BRAF, and ALK mutations (MC2). MC1 showed higher tertiary lymphoid structures signature scores and enriched populations of C2-T-IL7R, C3-T/NK-CXCL4, C9-T/NK-NKG, and C1-B-MS4A1 clusters than cluster 2. Conversely, MC2 cells exhibited higher expression levels of TNF, IL1B, and chemokines linked to alternative immune pathways. Remarkably, co-occurring EGFR and TP53 mutations were grouped as MC1. EGFR+TP53 mutations showed upregulation of peptide synthesis and higher synthetic processes, as well as differences in myeloid and T/NK cells compared to EGFR mutations. In T/NK cells, EGFR+TP53 mutations showed a higher expression of features related to cell activity and differentiation, whereas EGFR mutations showed the opposite. Conclusion Our research indicates a close association between mutation types and tumor microenvironment in NSCLC, offering insights into personalized approaches for cancer diagnosis and treatment.

An implant-supported hybrid prosthesis is a fixed restoration composed of a metal framework and acrylic resin, offering advantages such as aesthetics, function, phonetics, and lip support, while providing retention and support through the splinting of implants with the metal framework. However, poor oral hygiene can lead to peri-implantitis, and long-term use may result in wear or fracture of the artificial teeth, causing reduced masticatory function and loss of vertical dimension. Traditionally, a new metal framework is cast for remanufacturing, but if the existing framework is intact, it can be reused for a more rapid and simplified protocol. This case involves a 58-year-old male patient with peri-implantitis, where some implants were removed and treated, and the superstructure was remanufactured using the existing metal framework. By preserving the existing metal framework during the remanufacturing of the implant-supported hybrid prosthesis, the treatment time and number of visits were reduced, minimizing patient discomfort.
