ObjectiveTo assess the risk of vector-born infectious diseases by monitoring the major vectors in the relevant venues of the 19th Hangzhou Asian Games in Fuyang competition area, so as to provide references for the prevention and control of vector in similar large-scale events or activities in the future. MethodsFrom April to October 2023, monitoring and evaluation of rodent, mosquito, fly and cockroach density levels were carried out in various venues and reception hotels in Fuyang competition area (venues and hotels were the 1st circle area, and various environments and places in the surrounding 500 meters were the 2nd circle area). SPSS 25.0 software was used to analyze the data, and chi-square test or Fisher’s precision probability test were used to calculate the qualified rate and positive rate. Moreover, the path index, landing index and Bretrau index were analyzed by Kruskal-Wallis H test. ResultsThe control effect of vector density in the 1st circle was significantly better than that in the 2nd circle. Since September, the monitoring indices of the venues in the two circles had reached the national A-level and B-level standard, respectively. The positive rate of rodent traces generally showed a trend of first increasing and then decreasing, and the peak was shown to occur in July and August, with the highest rate of 5.38%. The qualified rate of rodent prevention facilities continued to rise, and facilities in the 1st and 2nd circles had reached national A-level and B-level standard respectively in late August. The landing index and path index of mosquitoes basically showed a changing trend from high to low, with the highest landing index of 4.56 individuals·person-time^-1 and the highest path index of 2.44 places·km^-1.The adult fly infestation rate remained at a low level, with the highest rate of 4.17%, and the minimum qualified rate of fly prevention facilities was 28.57%, which reached the national standard after July. The positive detection rates of adult flies and cockroach traces showed no significant pattern, with the highest rate of 7.00% and 8.33%, respectively. The detection rate of live ootheca was always at a low level. ConclusionThe relevant venues in the Fuyang competition area of the 19th Asian Games in Hangzhou meet national standards in terms of vector control indicators such as rodents, mosquitoes, flies, cockroaches and other vectors. By means of environmental improvement, facilities for preventing rodents and flies, and deepening biological and chemical prevention and control methods, it can be ensured that there will be no vector-borne diseases and infestation incidents during the event.

Sepsis is a systemic inflammatory response syndrome caused by the invasion of pathogenic microorganisms such as bacteria. In addition to the manifestations of systemic inflammatory response syndrome and primary infection lesions， critical cases often have manifestations of organ hypoperfusion. The morbidity and mortality of sepsis have remained high in recent years， which seriously affect the quality of life of the patients. The pathogenesis of sepsis is complicated， in which uncontrollable inflammation is a key mechanism. The phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） signaling pathway plays a key role in mediating inflammation in sepsis. The available therapies of sepsis mainly include resuscitation， anti-infection， vasoactive drugs， intensive insulin therapy， and organ support， which show limited effects of reducing the mortality. Therefore， finding new therapeutic drugs is a key problem to be solved in the clinical treatment of sepsis. In recent years， studies have shown that traditional Chinese medicine （TCM） can regulate the PI3K/Akt pathway via multiple pathways， multiple effects， and multiple targets to inhibit inflammation and curb the occurrence and development of sepsis， which has gradually become a hot spot in the prevention and treatment of sepsis. Moreover， studies have suggested that TCM has unique advantages in the treatment of sepsis. TCM can regulate the PI3K/Akt signaling pathway to inhibit inflammation， reduce oxidative stress， and control apoptosis in the prevention and treatment of sepsis. Despite the research progress， a systematic review remains to be performed regarding the TCM treatment of sepsis by regulating the PI3K/Akt signaling pathway. After reviewing relevant papers published in recent years， this study systematically summarizes the relationship between PI3K/Akt pathway and sepsis and the role of TCM in the treatment of sepsis， aiming to provide new ideas for the potential treatment of sepsis and the development of new drugs.

ObjectiveTo evaluate the efficacy and safety of Xiaoji Hufei Formula in protecting children with close contact exposure to influenza， and to provide reference and evidence-based support for better clinical prevention and treatment of influenza in children. MethodsA multicenter， prospective， non-randomized， parallel， controlled trial was conducted from October 2021 to May 2022 in five hospitals， including Dongfang Hospital of Beijing University of Chinese Medicine. Confirmed influenza cases and influenza-like illness （ILI） cases were collected， and eligible children with close contact exposure to these cases were recruited in the outpatient clinics. According to whether the enrolled close contacts were willing to take Xiaoji Hufei formula for influenza prevention， they were assigned to the observation group （108 cases） or the control group （108 cases）. Follow-up visits were conducted on days 7 and 14 after enrollment. The primary outcomes were the incidence of ILI and the rate of laboratory-confirmed influenza. Secondary outcomes included traditional Chinese medicine （TCM） symptom score scale for influenza， influenza-related emergency （outpatient） visit rate， influenza hospitalization rate， and time to onset after exposure to influenza cases. ResultsA total of 216 participants were enrolled， with 108 in the observation group and 108 in the control group. Primary outcomes： （1） Incidence of ILI： The incidence was 12.0% （13/108） in the observation group and 23.1% （25/108） in the control group， with the observation group showing a significantly lower incidence （χ²=4.6， P<0.05）. （2） Influenza confirmation rate： 3.7% （4/108） in the observation group and 4.6% （5/108） in the control group， with no statistically significant difference. Secondary outcomes： （1） TCM symptom score scale： after onset， nasal congestion and runny nose scores differed significantly between the two groups （P<0.05）， while other symptoms such as fever， sore throat， and cough showed no significant differences. （2） Influenza-related emergency （outpatient） visit rate： 84.6% （11 cases） in the observation group and 96.0% （24 cases） in the control group， with no significant difference. （3） Time to onset after exposure： The median onset time after exposure to index patients was 7 days in the observation group and 4 days in the control group， with a statistically significant difference （P<0.05）. ConclusionIn previously healthy children exposed to infectious influenza cases under unprotected conditions， Xiaoji Hufei formula prophylaxis significantly reduced the incidence of ILI. Xiaoji Hufei Formula can be recommended as a specific preventive prescription for influenza in children.

Objective To investigate value and risk factors of pelvic floor three-dimensional ultrasound parameters in single spontaneous delivery primipara with bladder neck funnel formation at 6-8weeks after delivery.Methods A total of 108 cases of single spontaneous delivery primipara were selected as research objects according to three-dimensional ultrasound indexes of pelvic floor,they were assigned into two groups:Observation group(40 cases)with bladder neck funnel formation and control group(68 cases)without bladder neck funnel formation.Three-dimensional ultrasound indexes of pelvic floor and clinical symptoms were compared between two groups.Results The incidence of stress urinary incontinence(SUI),anterior vaginal wall prolapse,bladder neck distance(BND),posterior urethrovesical angle(PUA)in Valsalva state,levator hiatus area(LHA)in resting and Valsalva states,levator hiatus length(LHL),and changes in LHL(△ LHL)in observation group were all higher than those in control group(P＜0.05).Logistic regression analysis revealed that SUI and anterior vaginal wall prolapse are independent risk factors for bladder neck funnel formation,adjusted OR were 11.255 and 3.643;Resting state and Valsalva state LHA,LHL,and △ LHL were also independent risk factors for bladder neck funnel formation(P＜0.05).Receiver operating characteristic(ROC)curve analysis revealed that area under the curve(AUC)for diagnosing bladder neck funnel formation in SUI and anterior vaginal wall prolapse were 0.744 and 0.615,respectively;In ultrasound indicators,when the LHL of Valsalva state is＞63.5mm,the AUC is 0.706;The diagnostic sensitivity of the combination factor 1(resting state LHA+Valsalva state LHA)is 95.0％;The diagnostic specificity of the combination factor 2(Valsalva state LHL+△LHL)is 80.9％.Conclusion In patients of single spontaneous delivery primipara with bladder neck funnel formation,occurrence of SUI and vaginal anterior wall prolapse,increased LHA and LHL under two states and △LHL were independent risk factors.The diagnostic sensitivity of the combination factor 1 was higher than single index,the diagnostic specificity of the combination factor 2 was higher.

Objective To investigate the efficacy and safety of hybrid surgery for the recanalization of carotid artery occlusion after stenting.Methods Clinical data and results of 17 patients with occlusion after carotid artery stenting and treated with hybrid surgery from June 2016 to April 2023 at the Department of Neurosurgery Cerebral Blood Flow Reconstruction Center of Xuanwu Hospital,Capital Medical University were retrospectively analyzed.According to whether the recanalization was successful,17 patients were divided into the the successful recanalization group and the failed recanalization group.Successful recanalization was defined as achieving modified thrombolysis in cerebral infarction(mTICI)grade ≥2b and residual stenosis＜50％.Baseline data(age,sex,body mass index,smoking history,alcohol consumption history,hypertension history,diabetes history,hyperlipidemia history,coronary heart disease history),clinical data(National Institutes of Health Stroke Scale[NIHSS]score at admission,fasting blood glucose,low density lipoprotein,high density lipoprotein,total cholesterol,triglyceride,occlusion side and segment,combination with severe stenosis or occlusion of the contralateral carotid artery,opening of the anterior communicating artery,opening of the posterior communicating artery,compensation of the external and internal carotid artery,compensation of the pia artery,stump morphology,and time from imaging diagnosis of occlusion to recanalization)were documented and compared between groups.The recanalization of occlusive vessels and perioperative complications were recorded.Imaging and clinical follow-up were performed 3,6 months and≥1 year after surgery.Results Among the 17 patients,the ratio of successful recanalization was 13/17.One patient had re-occlusion after operation,which was re-opened after thrombolysis,but neck hematoma with dyspnea occurred,and recovered after emergency operation.There was no postoperative stroke or death.The incidence of perioperative complications was 1/17.Compared with the successful recanalization group,the levels of high density lipoprotein and total cholesterol in the failed recanalization group were higher,and the differences between the groups were statistically significant(high density lipoprotein[1.3±0.3]mmol/L vs.[0.9±0.3]mmol/L,t=-2.139;total cholesterol:[4.2±0.8]mmol/L vs.[3.1±0.7]mmol/L,t=-2.649;both P＜0.05);There were no significant differences in other baseline data and clinical data(all P＞0.05).Imaging follow-up was completed in 9 of the 13 patients in the successful recanalization group,and the follow-up time was 3.8-36.9 months,with a median follow-up time of 22.8(12.8,34.7)months.Among them,1 patient(1/9)developed restenosis of recanalization vessels at 33.0 months after surgery and underwent stent implantation again.Conclusions The preliminary analysis showed that the occlusion after carotid artery stenting had better recanalization success and lower perioperative complications.In patients with chronic occlusion after carotid stenting,the application of a hybrid surgery for opening may be attempted under multimodal imaging assessment.

In recent years,radiation therapy has become a cornerstone in the treatment of head and neck tumors,significantly improving patient survival rates.However,the issue of radiation-induced carotid artery stenosis has garnered increasing attention.Characterized by multiple,long-segment,and unstable lesions,radiation-induced carotid stenosis presents unique challenges that traditional therapeutic approaches struggle to address.This review systematically summarized the pathological features and underlying mechanisms of radiation-induced carotid stenosis,with a focus on the roles of endothelial cells,smooth muscle cells,and vasa vasorum damage.Future research directions and preventive strategies are also discussed.

Objective:To analyze the prognostic outcomes of 1 147 patients who underwent liver transplantation at Qingdao University Affiliated Hospital and to summarize measures to enhance the efficacy of liver transplantation.Methods:A retrospective analysis was conducted on the clinical and follow-up data of 1 147 liver transplant patients at Qingdao University Affiliated Hospital.Results:The overall postoperative 1-, 3-, and 5-year survival rates for the 1 147 liver transplant patients were 87.20%, 73.40%, and 65.60%, respectively. The survival rates for benign disease liver transplant recipients were 88.01%, 84.98%, and 81.39% at 1, 3, and 5 years post-transplant, respectively, compared to recipients transplanted for malignancies of 78.11%, 64.41%, and 60.06% (all P<0.001). Among the mid vs more recent period, patients' 1-year and 3-year postoperative survival rates were 84.20%, 70.80% vs 90.50%, 71.70%, respectively,significantly in favor of recently enrolled patients ( P=0.022). In the complex surgery group, patients' 1-, 3-, and 5-year survival rates were 82.70%, 65.50%, 56.70%, while in less complicated group, it was 89.00%, 76.50%, 69.20% ( P<0.001). The primary causes of death for benign disease recipients were multi-organ failure (4.1%), while in recipients with malignant disease primary cause of death was tumor recurrence (23.7%). Postoperative complications included primary graft dysfunction, delayed graft function recovery, portal vein thrombosis, hepatic artery thrombosis, biliary stricture, post-transplant lymphoproliferative disorder, and graft-versus-host disease, with occurrence rates of 1.05%, 6.89%, 1.92%, 0.44%, 2.00%, 0.61%, and 0.44%, respectively. Conclusions:With the continuous improvement in surgical techniques and perioperative care levels, the 3-year survival rate of recipients at our center has increased. Malignant diseases and complex liver transplantation remain crucial factors affecting recipient prognosis, highlighting the need to further enhance comprehensive treatment capabilities for patients with malignant diseases and complex surgeries.
