Influenza virus pneumonia （IVP） is an acute inflammatory disease of the lung with high incidence rate and infectivity caused by invading of the virus into the lower respiratory tract. At present, the treatment of IVP is mainly based on anti-influenza virus infection strategies, including the use of influenza vaccines and anti-influenza virus drugs. Due to the strong variability of viral antigens, it is difficult to obtain long-lasting immunity through vaccination. Commonly used chemical//biological antiviral drugs usually target a single specific viral protein. The mutation and evolution of the virus can reduce its efficacy or render it ineffective, which may lead to drug resistance, limiting the clinical application of these treatment options. Traditional Chinese Medicines （TCMs） have a long history in the prevention and treatment of IVP and are widely used in clinical practice due to their unique advantages and clear therapeutic effects. The research progress on the pathogenesis of IVP, effective prevention and treatment of TCMs for IVP, and the mechanism of action of its active ingredients were reviewed, which could provide new ideas for the treatment of IVP and reference for the development of new multi-target and low toxicity drugs.

Objective:To evaluate the effectiveness of opioid-free anesthesia on postoperative outcomes in elderly patients following laparoscopic cholecystectomy.Methods:In this randomized controlled trial, 90 patients of either sex, aged 65-75 yr, with a body mass index of 18.5-23.9 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, scheduled for elective laparoscopic cholecystectomy, were divided into 2 groups ( n=45 each) using a table of random numbers: conventional general anesthesia group (GA group) and opioid-free anesthesia group (OFA group). Anesthesia was induced with intravenous etomidate, sufentanil and cisatracurium besylate and maintained with infusion of propofol and remifentanil combined with inhalation of sevoflurane in GA group. In OFA group, bilateral ultrasound-guided transversus abdominis plane block was performed via the posterior gluteal approach (injection of 0.25% ropivacaine 20 ml respectively) before anesthesia induction, anesthesia was induced with intravenous dexmedetomidine, esketamine, etomidate and cisatracurium besylate and maintained with infusion of dexmedetomidine, esketamine and propofol combined with inhalation of sevoflurane. In both groups, mechanical ventilation was performed with a laryngeal mask airway after anesthesia induction, and ketorolac tromethamine 30 mg (for postoperative analgesia) and metoclopramide 10 mg (to prevent postoperative nausea and vomiting) were intravenously injected at the end of surgery. The intraoperative adverse cardiovascular events, emergence time, laryngeal mask airway removal time, time of postanesthesia care unit stay, and postoperative rescue analgesia, nausea and vomiting and delirium were recorded. Results:No gallbladder cardiac reflex was found during operation in either group. Compared with GA group, the incidence of intraoperative bradycardia (11% versus 22%) was significantly increased ( P<0.05), the incidence of intraoperative hypotension and postoperative nausea, vomiting and delirium (17% versus 8%, 29% versus 16%, 16% versus 4% and 18% versus 4%), and requirements for rescue analgesia and antiemetics (31% versus 7% and 13% versus 4%) were decreased ( P<0.05), the postoperative emergence time, time of laryngeal mask airway removal and time of postanesthesia care unit stay were prolonged ( P<0.05), and no statistically significant difference was found in discharge time in OFA group ( P>0.05). Conclusions:The results of this study, as a single-center, small-sample randomized controlled trial, indicate that referenced to conventional general anesthesia, opioid-free anesthesia (esketamine-dexmedetomidine based anesthesia combined with bilateral transversus abdominis plan block) can improve the short-term postoperative outcomes to a certain extent in elderly patients following laparoscopic cholecystectomy.

Objective To investigate the effect of Modified Renshen Wumei Decoction on the TLR4/MyD88/pNF-κBp65 signaling pathway and elucidate the potential mechanism by which this formula repairs the intestinal mucosal barrier in diarrheal rats.Methods Twelve rats were randomly selected from a total of 48 rats to serve as the blank control group(CK),while the remaining 36 rats were used to establish a disease model via a compound method.After 14 days of model preparation,the rats were randomly divided into three groups:the model group(MC),the western medicine group(MV),and the traditional Chinese medicine group(MRWD).Each of the four groups(including CK)received corresponding interventions for 7 days.The concentrations of serum diamine oxidase(DAO),D-lactic acid(D-Lac),interleukin-1β(IL-1β),IL-6,IL-10,tumor necrosis factor-α(TNF-α),mucin 2(MUC2),MUC4,MUC6,and colonic homogenate secretory immunoglobulin A(SIgA)were measured using ELISA.Additionally,the protein and gene expressions of colonic toll-like receptor 4(TLR4),myeloid differentiation primary response 88(MyD88),phosphorylated nuclear factor kappa-light-chain-enhancer of activated B cells p65(pNF-κBp65),occludin,claudin-1,and zonula occludens-1(ZO-1)were analyzed by Western blot and RT-PCR.Results(1)Intestinal mucosal injury markers:Compared with the blank group,the serum levels of DAO and D-Lac in the model group were significantly increased(P<0.05).Compared with the model group,both the Chinese medicine group and Western medicine group significantly decreased the serum levels of DAO(P<0.001),while the traditional Chinese medicine group also significantly reduced the serum levels of D-Lac(P<0.05).There was no significant difference in the changes of DAO and D-Lac serum levels between the Chinese medicine group and Western medicine group(P>0.05).(2)Inflammatory indicators:Compared with the blank group,the model group exhibited significant upregulation of TLR4,MyD88,pNF-κ Bp65 protein and gene expression,as well as serum levels of IL-1β,IL-6,and TNF-α(P<0.05),along with a significant decrease in IL-10 serum levels(P<0.05).Compared with the model group,both the Chinese medicine group and Western medicine group significantly downregulated TLR4,MyD88,pNF-κBp65 protein and gene expression,as well as serum levels of IL-1β,IL-6,and TNF-α(P<0.05),and significantly upregulated IL-10 serum levels(P<0.05).There was no significant difference in serum levels of TLR4,MyD88,pNF-κBp65 protein,gene expression,and IL-1β,IL-6,IL-10,and TNF-α between the Chinese medicine group and Western medicine group(P>0.05).(3)Intestinal mucosal barrier factors:Compared with the blank group,the model group exhibited significant downregulation in MUC2,MUC6,SIgA content,as well as Claudin-1,ZO-1 protein and gene expression,and Occludin protein expression(P<0.05).Compared with the model group,both Chinese and Western medicine groups significantly upregulated the content of MUC2 and SIgA,as well as the protein and gene expression of Claudin-1 and ZO-1(P<0.05).The traditional Chinese medicine group also significantly increased the content of MUC6 and Occludin protein expression(P<0.05).No significant differ-ences were observed between the Chinese and Western medicine groups in terms of MUC2,MUC6,SIgA serum content,and Claudin-1 and ZO-1 gene expression(P>0.05).However,the Western medicine group showed better Claudin-1 protein expression than the Chinese medicine group(P<0.05),while the ZO-1 protein expression was higher in the traditional Chinese medicine group compared to the Western medicine group(P<0.05).Conclusion Modified Renshen Wumei Decoction exerts an intestinal mucosal barrier repair effect in diarrhea rats by modulating the TLR4/MyD88/pNF-κBp65 signaling pathway.

Objective To analyze the type and incidence of abnormal chromosome karyotype in peripheral blood of infertile patients with different semen quality.Methods Selectet 292 infertility patients who came to our hospital from January 2018 to December 2021 for G-banding karyotyping and semen analysis.According to the semen analysis results,the patients were divided into abnormal semen quality group and normal control group.We made statistics and analysis on the abnormal karyotypes.Results In the group with abnormal semen quality,20 cases(18.87%)of abnormal karyotypes were found.In the normal control group,9 cases(4.84%)had abnormal karyotypes were found.The comparison of the abnormal rates of peripheral blood chromosome karyotypes between the two groups showed statistical significance(P<0.05).The detection rate of chromosomal abnormalities in patients with Azoospermia was 50%,and sex chromosome abnormalities were the main types of abnormalities in this group.Conclusion Karyotype analysis of infertile patients can effectively analyze the causes of infertility,and has important clinical significance for assisted reproduction and primary prevention of birth defects.

Objective To retrospectively analyze of factors influencing early preterm birth(EPB)and late preterm birth(LPB)in pregnancy women with placenta previa complicated by placenta accreta spectrum disorders(PAS),and assess maternal and infant outcomes.Methods We included 590 cases of pregnancy women with placenta previa complicated by PAS who underwent cesarean sections at five hospitals in Wuhan and Xianning cities between January 2018 and June 2021.These patients were divided into three groups based on delivery gesta-tional age:EPB,LPB,and term birth(TB).A multiple logistic regression model was employed to analyze the risk factors associated with EPB and LPB.Additionally,differences in early maternal and infant outcomes among these groups were examined.Results Among 590 pregnancy women with placenta previa complicated by PAS,the proportions of EPB and LPB were 9.7%and 54.4%.The use of uterine contraction inhibitors prior to cesarean section,vaginal bleeding,and previous cesarean sections history were identified as risk factors for both EPB and LPB.The proportion of severe postpartum hemorrhage was comparable between the EPB group and the LPB group;however,the incidence of neonatal asphyxia,low birth weight infants,and the rate of newborns transferred to the Neonatal Intensive Care Unit(NICU)within 24 hours after cesarean delivery were significantly higher in the EPB group compared to the LPB group.Conclusions Placenta previa complicated by PAS predominantly leads to LPB.The history of prior cesarean sections,uterine contractions,and vaginal bleeding prior to cesarean section,are sig-nificantly associated with both EPB and LPB.During the perinatal period,efforts should be made to extend gesta-tional weeks under close monitoring to minimize the incidence of premature births and thereby improve early mater-nal and infant outcomes.

Objective: Autism spectrum disorder (ASD) is a neurodevelopmental disorder with onset in infancy. Early intervention is critical to improve the prognosis for these children. E-health interventions have tremendous potential. This review aimed to determine the status and effectiveness of family interventions for parents of children aged 0–6 years with ASD in the context of e-health. Methods: The review methodology was guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. PubMed, Web of Science, and China National Knowledge Infrastructure were searched from inception to June 2022. The searches were limited to children with ASD of the age range between 0 and 6 years. We collated the available information and used descriptive statistics to analyze the synthesized data. Results: Our initial search identified 3,672 articles, of which 30 studies met the inclusion criteria. The 30 articles selected were released between 2012 and 2022. All articles are in English. Most articles reviewed were from high-income countries (27/30, 90.0%), especially from the United States (16/30, 53.3%). Four major themes emerged from the 30 studies that matched the inclusion criteria, as follows: 1) type of e-health interventions, 2) duration of interventions, 3) clinical aspects of e-health interventions, and 4) evidence for intervention effectiveness, looking into the positive, negative, and mixed findings of previous studies. Conclusion These findings suggest that a wide variety of e-health interventions may actually help support both children with ASD aged 0–6 years and their parents.
