To summarize the distribution characteristics of human papillomavirus(HPV) infection types in patients with cervical squamous intraepithelial lesion(SIL) and cervical cancer(CC), and to explore the impact of HPV vaccination, HPV infection types, and general clinical data on different grades of cervical lesions.

Objective To investigate the effect and mechanism of nodakenin(Nod)in neuropathic pain(NP).Methods Differential expression genes in the primary somatsensory cortex(S1)of NP data and overlapping genes between the dataset and mitochondrial data were screened and analyzed.Overlapping gene interaction networks were overlapped and core genes were screened.A total of 27 mice were randomly divided into the sham operation group,the model group and the drug administration group(9 mice/group).The chronic compression injury model of sciatic nerve was constructed in the model group and the drug administration group.Nod 10 mg/kg was intraperitoneally injected into the drug administration group for 1 week.Changes of pain behavior and motor ability in mice were detected.HE staining and Nissl staining were used to detect effects of nerve injury and inflammation on brain tissue of S1 region of mice.The expression levels of interleukin-1β,early gene(c-Fos),panthenol-cytochrome c reductase complex III subunit(Uqcrq)and ubiquinone oxidoreductase subunit(Nduf)b5 in S1 brain region were analyzed by Western blot assay.Molecular docking was used to study the target of Nod.PC12 cells were divided into the control group,the IL-1β group(1 μmol/L IL-1β treatment)and the IL-1β+Nod group(1 μmol/L IL-1β+1 μmol/L Nod treatment),and mitochondrial membrane potential was detected in each group.Results In the NP dataset GSE180627,S1 brain region contained 293 differentially expressed genes,and the mitochondrial data contained 1 082 genes.There were 34 overlapping genes,and genes related to oxidative phosphorylation and electron transport chain were enriched.The protein interaction network showed that core genes included electron transport chain related proteins Ndufb5,Uqcrq,Ndufs8,Ndufa7,Ndufa3,Cox6b1 and Mrps33.Compared with the model group,the mechanical foot shrinkage threshold,thermal foot shrinkage reflex latency and rod rotation residence time of mice were increased in the drug administration group,the number of inflammatory infiltrating cells in S1 tissue and the number of Nislet bodies in neurons,expression levels of c-Fos and IL-1β in neurons were decreased,and expression levels of Uqcrq and Ndufb5 were increased(P＜0.05).Molecular docking showed that Nod could bind Uqcrq and Ndufb5.Compared with the IL-1β group,the fluorescence signal of mitochondrial membrane potential was enhanced in the IL-1β+Nod group(P＜0.05).Conclusion Nodakenin can improve pain behavior in mice,and its mechanism involves ameliorating mitochondrial damage in S1.

Objective To explore the mechanism of Quhan Zhufeng Mixture on proliferation and apoptosis of rheumatoid arthritis fibroblast-like synoviocyte(RA-FLS)based on NDRG2/JAK2/STAT3 signaling pathway.Methods RA-FLS cells were cultured in vitro,and were divided into ① blank serum group,methotrexate group,Quhan Zhufeng Mixture low-,medium-and high-dosage groups;② blank serum group,AG490 group,Quhan Zhufeng Mixture low-,medium-and high-dosage groups.Different concentrations of drug-containing serum were used to intervene cells.Cell proliferation was detected by CCK-8 method,apoptosis was detected by flow cytometry,and mRNA expressions of Bax,Bcl-2,Caspace-3,Caspace-9,N-myc downstream regulatory gene 2(NDRG2),Janus kinase 2(JAK2)and signal transduction and transcription activator 3(STAT3)were detected by RT-qPCR,Western blot was used to detect the protein expressions of Bax,Bcl-2,Caspace-3,Caspace-9,NDRG2,JAK2,STAT3,p-JAK2 and p-STAT3 in cells.Results Compared with the blank serum group,cell survival rate in methotrexate group,Quhan Zhufeng Mixture all dosage groups significantly decreased(P<0.01),the apoptosis rate significantly increased(P<0.01),the mRNA and protein expressions of Bax and Caspase-9 significantly increased(P<0.05,P<0.01),while the mRNA and protein expression of Bcl-2 significantly decreased(P<0.01),and Caspase-3 mRNA and protein expression in methotrexate group and Quhan Zhufeng Mixture medium-and high-dosage groups significantly increased(P<0.01).Compared with the blank serum group,the mRNA and protein expression of NDRG2 significantly increased in Quhan Zhufeng Mixture all dosage groups(P<0.05,P<0.01),the mRNA and protein expressions of JAK2 and STAT3 were significantly reduced in AG490 group and Quhan Zhufeng Mixture medium-and high-dosage groups(P<0.05,P<0.01),and the expressions of p-JAK2 and p-STAT3 proteins were significantly reduced(P<0.01).Conclusion Quhan Zhufeng Mixture can regulate the proliferation and apoptosis of RA-FLS by regulating the activity of NDRG2/JAK2/STAT3 signaling pathway,playing a role in treating rheumatoid arthritis.

Objective To explore the influencing factors of hypothermia after extraperitoneal laparoscopic radical prostatectomy in prostate cancer patients over 80 years old,so as to improve the effectiveness of treatment.Methods The clinical data of 26 cases of prostate cancer patients over 80 years old who underwent extraperitoneal laparoscopic radical prostatectomy in Shanghai 411 hospital from January 2021 to December 2023 were analyzed retrospectively.The incidence of postoperative hypothermia was investigated.Univariate and multivariate Logistic regression analyses were used to analyze the related factors of postoperative hypothermia in elderly patients.Results The incidence of hypothermia was 61.54%(16/26).Univariate analysis indicated that body mass index(BMI),intraoperative thermal insulation,intraoperative infusion volume,operation time,and anesthesia time were related to the occurrence of postoperative hypothermia in elderly patients(all P<0.05).Multivariate Logistic regression analysis indicated that BMI≤24,intraoperative infusion volume>2 000 ml,anesthesia time>3 h and operation time>2.5 h were high risk factors for postoperative hypothermia in patients over 80 years old.Conclusion The independent influencing factors of hypothermia after extraperitoneal laparoscopic prostatectomy for selected prostate cancer patients over 80 years old are BMI,intraoperative infusion volume,duration of anesthesia,and operation time.These factors should be paid more attention during perioperative period in order to improve clinical safety.

Alternative splicing (AS) is a crucial process that produces functionally distinct proteins from a single gene, depending on the developmental or physiological state of cells in multicellular organisms. It plays a significant role in cellular proliferation, survival, and differentiation, including embryonic development, spermatogenesis, and a broad spectrum of diseases. However, the precise involvement of AS in embryo implantation is still unclear. In this review, we summarize the potential roles of AS in regulating mesenchymal-epithelial transitions during embryo implantation, specifically in epithelium regeneration and decidualization initiation via the mesenchymal-epithelial transformation process. Overall, this review emphasizes the impact of AS and splicing variants on embryo implantation and offers novel insights into the potential application of alternative splicing in the treatment of female infertility.

To reduce the subjectivity and uncertainty present in the current international methods of drug value pricing when converting value into monetary prices,based on the hedonic pricing theory,it considers the post-negotiation price between manufacturers and payers as a reasonable price reference in the value pricing of Chinese patent medicine.By constructing an indicator system for the characteristics of Chinese patent medicine,it selects and measures the value characteristic variables that affect the price of Chinese patent medicine.It serves as the theoretical foundation and research basis for establishing a Hedonic price model between characteristic price variables and negotiation prices,thereby promoting the enhancement of rationality and objectivity in value-guided pricing of Chinese patent medicine.
