Objective High-risk human papillomavirus(HR-HPV)infection is the chief cause of cervical intraepithelial neoplasia(CIN)and cervical carcinoma.The Erhuang suppository(EHS)is a traditional Chinese medicine(TCM)prepared from realgar(As_(2)S_(2)),Coptidis rhizoma,alumen,and borneolum syntheticum and has been used for antiviral and antitumor purposes.However,whether EHS can efficiently alleviate HR-HPV infection remains unclear.This study was conducted to evaluate the efficacy of EHS for the treatment of persistent HR-HPV infection in the uterine cervix.Methods In this study,we evaluated the therapeutic efficacy of EHS in a randomized controlled clinical trial with a 3-month follow-up.Totally,70 patients with persistent HR-HPV infection were randomly assigned to receive intravaginal administration of EHS or placebo.HPV DNA,ThinPrep cytologic test(TCT),colposcopy,and safety evaluation were carried out after treatment.Microarray analysis was performed to compare transcriptome profiles before and after EHS treatment.A K14-HPV16 mouse model was generated to confirm the efficiency of EHS.Results After 3 months,74.3%(26/35)of the patients in the treatment group were HPV negative,compared to 6.9%(2/29)in the placebo group.High-throughput microarrays revealed distinct transcriptome profiles after treatment.The differentially expressed genes were significantly enriched in complement activation,immune response,and apoptotic processes.The K14-HPV16 mouse model also validated the remarkable efficacy of EHS.Conclusion This study demonstrated that EHS is effective against HR-HPV infection and cervical lesions.Additionally,no obvious systemic toxicity was observed in patients during the trial.The superior efficacy and safety of EHS demonstrated its considerable value as a potential cost-effective drug for the treatment of HPV infection and HPV-related cervical diseases. 展开更多

Objective This study aims to identify the effect of third interstitial fluid on adverse outcomes in twin pregnancies with severe pre-eclampsia,and explore the differences in bad ending between twins and singletons.Methods The present retrospective cohort study was conducted on patients with severe pre-eclampsia,who delivered in Tongji Hospital,Wuhan,China,between 2017 and 2022.The adverse outcomes in singleton and twin pregnancies with severe pre-eclampsia were initially investigated.Then,the diverse maternal and fetal consequences between singleton and twin pregnancies in patients with severe pre-eclampsia were compared after merging with the third interstitial fluid.Results A total of 709 patients were included for the present study.Among these patients,68 patients had twin pregnancies,and 641 patients had singleton pregnancies.The rate of postpartum hemorrhage(2.81%vs.13.24%,P<0.001),and admission rate to the Neonatal Intensive Care Unit(NICU)after birth(30.73%vs.63.24%,P=0.011)were significantly higher in twin pregnancies.The neonatal weight of twins was statistically lower than singletons(1964.73±510.61 g vs.2142.92±731.25 g,P=0.008).For the groups with the third interstitial fluid,the delivery week(P=0.001)and rate of admission to the NICU after birth were significantly advanced in twin pregnancy group,when compared to singleton pregnancy group(P=0.032),and the length of hospital stay was shorter(P=0.044).Furthermore,there was no statistically significant difference between the twin pregnancy group and the singletony pregnancy group without the third interstitial fluid.Conclusion The maternal and fetal adverse outcomes of patients with severe pre-eclampsia increased in twin pregnancies,when compared to singleton pregnancies.Thus,when patients develop the third interstitial fluid,twin pregnancies would more likely lead to adverse fetal outcomes,when compared to singleton pregnancies,and there would be no significant difference in maternal adverse outcomes.More attention should be given to patients who merge with the third interstitial fluid. 展开更多

This paper discusses the fixed-hub single allocation problem(FHSAP).In this problem,a network consists of hub nodes and terminal nodes.Hubs are fixed and fully connected;each terminal node is assigned to a single hub which routes all its traffic.The goal is to minimize the cost of routing the traffic in the network.In this paper,we propose a new linear programming(LP)relaxation for this problem by incorporating a set of validity constraints into the classical formulations by Ernst and Krishnamoorthy(Locat Sci 4:139–154,Ann Op Res 86:141–159).A geometric rounding algorithm is then used to obtain an integral solution from the fractional solution.We show that by incorporating the validity constraints,the strengthened LP often provides much tighter upper bounds than the previous methods with a little more computational effort and the solution obtained often has a much smaller gap with the optimal solution.We also formulate a robust version of the FHSAP and show that it can guard against data uncertainty with little costs. 展开更多

In this paper,we present a unified framework for decision making under uncertainty.Our framework is based on the composite of two risk measures,where the inner risk measure accounts for the risk of decision if the exact distribution of uncertain model parameters were given,and the outer risk measure quantifies the risk that occurs when estimating the parameters of distribution.We show that the model is tractable under mild conditions.The framework is a generalization of several existing models,including stochastic programming,robust optimization,distributionally robust optimization.Using this framework,we study a few new models which imply probabilistic guarantees for solutions and yield less conservative results compared to traditional models.Numerical experiments are performed on portfolio selection problems to demonstrate the strength of our models. 展开更多
