ObjectiveTo analyze the incidence and spatiotemporal distribution of typhus fever in Baoshan City, Yunnan Province from 2005 to 2023, to identify high-risk populations and regions, so as to provide a scientific basis for optimizing the allocation of local prevention and control resources and developing targeted intervention measures. MethodsData of typhus fever cases in Baoshan City from 2005 to 2023 were obtained from the Infectious Disease Information Management System of the Chinese Center for Disease Control and Prevention. Descriptive epidemiological methods were used to analyze the temporal, spatial and demographic distribution of typhus fever cases. Spatial clustering was assessed using spatial dynamic window scan statistics (circular and elliptical windows), flexible spatial scan statistics, and local spatial autocorrelation methods (including local Moran’s I, local Geary’s C, and Getis-Ord G_i*). Retrospective spatiotemporal scan statistics were employed to detect spatiotemporal clusters. ResultsA total of 1 099 typhus fever cases were reported in Baoshan City from 2005 to 2023. The incidence rate peaked at 6.31/ 100 000 in 2007, followed by a decline until reaching its lowest level at 0.21/100 000 in 2015 , and subsequently rebounded during 2016‒2023. The highest proportion of cases was among children under 10 years of age (31.12%), and the top three occupations of cases were farmers, students, and children, accounting for 88.62% of all cases. Cases occurred predominantly between June and September each year. The incidence was relatively high in Jiucheng Town (62.58/100 000), Yaoguan Town (57.15/100 000), and Dianyang Town (46.81/100 000) of Shidian County. Spatial clustering analyses indicated that high-risk areas were mainly located in the southern part of Baoshan City, showing a south-to-north trend. Spatiotemporal scan analyses identified five clusters, with the most likely cluster centered around Yaoguan Town, covering ten towns (subdistricts) during the period 2007‒2010. ConclusionThe incidence of typhus fever in Baoshan City exhibits a clear seasonal and spatial clustering pattern, with peak incidence occurring in summer and autumn. Spatially, cases are primarily distributed in the southern part of Baoshan City, and high-risk clusters exhibit a south-to-north trend. Farmers, students, and children are the high-risk groups.

This paper summarizes the exploration process and academic significance of the academic thought of Zhou Zhongying,a master of traditional Chinese medicine,who took the creation of a new system of TCM pathogenesis theory as the core,and interprets its theoretical connotation.As a pioneer in the construction of higher education textbooks for traditional Chinese medicine,Professor Zhou Zhongying created the outline of TCM internal medicine viscera differentiation,persisted in carrying out innovative research on patho-genesis theory,achieved fruitful academic results,and enriched and developed the academic system of TCM theory.In the clinical di-agnosis and treatment of exogenous febrile diseases and acute and difficult internal injuries,he systematically created new pathogenesis theories such as stasis-heat theory and cancer toxicity theory.Based on this,the legislation of medication can improve the clinical effi-cacy,and it is realized that identifying the pathogenesis is the key link in syndrome differentiation and treatment.In his later years,Professor Zhou Zhongying,guided by the holistic view,proposed the"thirteen pathogenesis"and constructed a new system of TCM pathogenesis differentiation,highlighting the guiding value of complex pathogenesis and the causal chain of pathogenesis elements to complex clinical diseases and syndromes,forming a theory with the idea of"examining syndromes and seeking pathogenesis,activating syndrome differentiation"as its soul.This theory breaks through the rigid thinking of syndrome differentiation and treatment based on a single pathogenesis or fixed syndrome type,reconstructs the theoretical framework of TCM with the idea of holistic view,and is a major academic innovation in modern TCM.

Objective To compare the clinical outcomes of all-inside arthroscopic and open recon-struction of the anterior talofibular ligament(ATFL)and calcaneofibular ligament(CFL).Methods The clinical data of 51 patients with chronic lateral ankle instability(CLAI)and treated in our department between January 2017 and July 2021 were analyzed retrospectively.Among them,24 received ar-throscopic ATFL and CFL reconstruction(arthroscopy group),while 27 underwent conventional surgery(open group).The perioperative data including surgical time,intraoperative complications,hospitaliza-tion duration and time to resume normal walking were compared between the two groups.Moreover,postoperative CT examination was performed to evaluate the position of the bone tunnel.Before as well as 3 months,6 months,1 year,and 2 years after the operation,both groups were evaluated using the American Orthopedic Foot and Ankle Society Score(AOFAS),Karlsson score,visual analogue scale(VAS),drawer test,and inversion test.Meanwhile,the occurrence of complications was also recorded and compared.Results Both groups underwent the surgery successfully.The total length of incision and time to resume normal walking in the arthroscopy group were significantly shorter than the open group(P<0.05),while there was no significant difference between them in surgical time and hospital stay(P>0.05).Postoperative CT showed that in the arthroscopy group,1 case had suboptimal talus bone tun-nel position,while in the open group,1 had suboptimal calcaneus bone tunnel position and another suffered from suboptimal talus bone tunnel position,with the remaining bone tunnels located within the corresponding footprint area.All patients were followed up for 24 to 33 months.Significant improve-ment was observed in the average AOFAS score,Karlsson score,and VAS score in both groups after the operation(P<0.05),and both the drawer and inversion tests were of negative results.Three months postoperatively,the arthroscopic group had significantly better AOFAS,Karlsson and VAS score than the open group(P<0.05).Moreover,at 6 months postoperatively,the average AOFAS and Karlsson scores of the arthroscopy group were significantly superior to the open group(P<0.05).However,1 year and 2 years postoperatively,no significant differences were found between the two group in the AOFAS,Karlsson and VAS score(P>0.05).Moreover,no serious complications occurred during surgery and follow-up in both groups.Conclusion The efficacy of arthroscopic reconstruction of ATFL and CFL is comparable to open reconstruction in treating CLAI,with the former therapy resulting in faster recov-ery.

Objective:This study proposed a novel technique for aortic root reconstruction and evaluated its safety and effectiveness.Methods:Acute type A aortic dissection (ATAAD) patients who underwent Sun' s procedure from January 2020 to June 2022 in the First Affiliated Hospital of Xi'an Jiaotong University were retrospectively enrolled. These patients were divided into three groups according to their surgical procedures of aortic root: aortic root reinforcement combined with vascular grafts built-in and intermittent anastomosis technique (XJ-procedure) group, continuous suture and pledgeted interrupted reinforcement group and Bentall group. The perioperative data and postoperative follow-up results of the three groups were compared to analyze the efficacy of XJ-procedure in the root treatment of ATAAD.Results:A total of 509 patients were enrolled in this study, including 288 patients in the XJ-procedure group, 132 patients in the continuous suture and pledgeted interrupted reinforcement group and 89 patients in the Bentall group. The 30-day mortality of all patients was 7.5% (38/509), and were 7.3%, 8.3% and 6.7% in the XJ-procedure group, continuous suture and pledgeted interrupted reinforcement group and Bentall group, respectively. The operation time of the XJ-procedure group [355 (320, 380) min] was significantly lower than the other two groups. The cardiopulmonary bypass time [154 (140, 169) min] and the aortic cross-clamping time [80 (72, 89) min] of XJ-procedure group were lower than the Bentall group [166 (147, 184) min and 86 (77, 96) min]. The aortic root bleeding that required secondary cardiopulmonary bypass did not occur in the XJ-procedure group. There was no significant difference in early postoperative complications among the three groups. The incidence of residual aortic root dissection before discharge, in 3 and 6 months after operation was lower in the XJ-procedure group compared to the continuous suture and pledgeted interrupted reinforcement group ( P<0.001). Conclusion:The XJ-procedure technique is a safe, simple and mastered method for the aortic root treatment of ATAAD, which shows an accurate early clinical effect.

The end of the COVID-19 infection peak in 2022 prompts a backlog of cardiovascular surgical patients to gradually return to the hospital, resulting in a surge in cardiovascular surgeries. However, against the backdrop of the COVID-19 pandemic, the clinical practice of cardiovascular surgery faces many problems. Therefore, organized by Beijing Anzhen Hospital, experts in cardiovascular surgery and related fields have formulated hospital expert experience on perioperative treatment principles of cardiovascular surgery for patients infected with COVID-19. This article summarizes the clinical decision-making of patients requiring cardiovascular surgery after COVID-19 infection, and advises on the corresponding recommendations according to the existing evidence-based medical evidence as well as the actual clinical practice experience of relevant experts. The main content of the article includes special requirements for cardiovascular surgical treatment indications in patients with COVID-19 infection, selection of surgical timing, special requirements of preoperative, intraoperative and postoperative management, etc., which aims to provide COVID-19-infected patients with guidance on rational decision-making when receiving cardiovascular surgery.

Objective:To investigate the effect of HLA-Cw*0602 and LCE3B_LCE3C-del allele interaction on the risk of psoriasis vulgaris in a population of Mongolian nationality in Inner Mongolia. Methods:A total of 365 Mongolian patients with psoriasis vulgaris who received treatment in The Affiliated Hospital of Inner Mongolia Medical University from January 2006 to December 2015 (case group) and 284 healthy subjects who concurrently received physical examination in the same hospital (control group) were included in this study. After sex and age matching, and quality control, the correlations between HLA-Cw*0602 and LCE3B_LCE3C-del allele and psoriasis vulgaris in a population of Mongolian nationality were analyzed using SPSS 20.0 software. The interaction between HLA-Cw*0602 and LCE3B_LCE3C-del alleles (adjusting for potential confounders including age and sex) was analyzed using logistic regression. Results:Logistic regression interaction item Int of dominant inheritance mode HLA-Cw*0602 allele and recessive inheritance mode LCE3C_LCE3B-del allele revealed OR = 2.38, P = 0.033, and interaction index S = 1.21, indicating that there was a synergistic effect between the two alleles. Conclusion:The co-existence of HLA-Cw*0602 and LCE3B_LCE3C-del may increase the risk of psoriasis vulgaris in a population of Mongolian nationality in Inner Mongolia.

Since mid-December 2019, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has outbroken in Wuhan, Hubei Province, China, and spread rapidly to other provinces in China and dozens of countries and regions around the world, becoming the Public Health Emergency of International Concern (Public Health Emergency of International Concern). SARS-CoV-2 can mainly transmit by droplets or close contact, and is generally susceptible in the crowd. Tumor patients are at high risk of this pathogen because of their impaired immune function. Identifying tumor patients with 2019 novel coronavirus disease (COVID-19) early, and understanding its distribution characteristics can help to improve the cure rate of patients, and better control the epidemic and development of SARS-CoV-2 much better. With comprehensive analysis of relevant literature, this paper reviews the clinical characteristics of neoplastic patients with COVID-19, and puts forward some suggestions on how to deal with this epidemic.
