Objective To comparatively explore the prognosis of hepatocellular carcinoma(HCC)patients with hepatitis B(HB)and hepatitis C(HC)after microwave ablation(MWA).Methods Data of 159 HCC patients with HB(HB-HCC)and 159 HCC patients with HC(HC-HCC)who received MWA treatment were retrospectively collected.The oncologic outcomes were compared between groups,the causes of death were analyzed,and the risk factors of overall survival(OS)in HCC patients after MWA were observed.Results The OS rate in HC-HCC group was lower than that in HB-HCC group(P=0.045),while no significant difference of disease free survival rate(P=0.095)nor cancer specific survival rate(P=0.180)was found between groups.Compared with HB-HCC group,HC-HCC group had higher risk of death due to complications related to liver cirrhosis(HR=2.339,P=0.043).Child-Pugh class B(HR=3.082,P＜0.001),hepatitis viral load＞500 IU/ml(HR=1.654,P=0.006)and the maximum diameter of lesion≥3.0 cm(HR=1.541,P=0.017)were all independent risk factors of OS in HCC patients after MWA.Conclusion Compared with HB-HCC patients,HC-HCC patients had shorter OS after MWA.

Objective To explore the value of quantitative CT(QCT)for assessing complications of type 2 diabetes mellitus(T2DM).Methods Totally 220 T2DM patients were included and divided into uncomplicated group(n=40),mono-complicated group(n=84)and multi-complicated group(n=96).Bone mineral density(BMD)of L2—L4,as well as visceral adipose tissue(VAT)and subcutaneous adipose tissue(SAT)area were collected using QCT and compared among groups.The operator characteristic curves were drawn,and the area under the curves(AUC)were calculated to observe the value of QCT indicators and comprehensive model based on clinical indicators and QCT indicators for evaluating complications of T2DM.Decision curve analysis(DCA)and clinical impact curve(CIC)analysis were used to analyze the clinical application value of the comprehensive model.Results Significant differences of patients’age,lumbar BMDs and areas of VAT were found among 3 groups(all P＜0.05).The AUC of comprehensive model for differentiating uncomplicated group from mono-complicated group,uncomplicated group from multi-complicated group and mono-complicated group from multi-complicated group was 0.753,0.865,and 0.761,respectively,higher than that of BMD,VAT and SAT area(all P＜0.05).DCA and CIC analyses showed that comprehensive model yielded clinical benefits and had good clinical applicability for assessing complications of T2DM.Conclusion QCT was valuable for assessing complications of T2DM.

Objective:To explore the current status of frailty among elderly inpatients in Zunyi City and analyze its influencing factors.Methods:From October 2022 to March 2023, convenience sampling was used to select elderly patients who were hospitalized and treated at six hospitals, namely the Affiliated Hospital of Zunyi Medical University, the Second Affiliated Hospital of Zunyi Medical University, the First People's Hospital of Zunyi, Guizhou Aerospace Hospital, Zunyi Hospital of Traditional Chinese Medicine, and People's Hospital of Honghuagang District, Zunyi, as the research subject. The study subjects were surveyed using the General Information Questionnaire, Barthel Index, Pittsburgh Sleep Quality Index, Geriatric Depression Scale, and Fatigue, Resistance, Ambulation, Illness, Loss of Weight Scale. Multivariate Logistic regression was used to analyze the influencing factors of frailty in elderly inpatients in Zunyi City.Results:A total of 4 013 questionnaires were distributed and 3 853 valid questionnaires were collected, with an effective response rate of 96.01% (3 853/4 013). The incidence of frailty in elderly inpatients was 15.05% (580/3 853). Multivariate Logistic regression analysis showed that the coexistence of multiple diseases, types of long-term medication, activities of daily living, sleep quality, and depression were the influencing factors for frailty in elderly inpatients ( P<0.05) . Conclusions:The incidence of frailty in elderly inpatients was high. Medical and nursing staff should pay attention to elderly inpatients with the coexistence of multiple diseases, long-term use of multiple medications, decreased activities of daily living, poor sleep quality, and depressive emotions, and develop targeted intervention measures for them.

Objective:To investigate effect of Gehua Jiecheng Decoction on IL-6/JAK2/STAT3 signaling pathway in colon tissue of ulcerative colitis with"inflammatory to cancer transformation"(UC-UCAC)mice of spleen deficiency and damp-heat type.Methods:Ten from 80 SPF C57BL/6 male mice were randomly selected as blank group and other 70 mice were selected as model group.After establishment of spleen deficient damp-heat model,mice were randomly divided into model group(1st,2nd and 3rd cycle),Gehua Jiecheng Decoction high,medium and low doses groups and mesalazine group,with 10 pieces per group.UC-UCAC transformation model was further established with azo methane oxide solution(AOM)/sodium glucan sulfate(DSS).Each group was treated with corresponding drugs for 4 weeks.General state of mice was observed.Score of disease activity index(DAI)was calculated.HE staining was used to observe colonic mucosa pathology of mice.EGFR,IL-6,JAK2,STAT3 and p-STAT3 proteins and genes expressions in mice colon tissues were detected by Western blot,IHC and RT-qPCR,respectively.Results:Compared with blank group,mice in model group(3rd cycle)were generally in a worse state,colon mucosal tissue was cancerous,DAI score,target proteins and genes expressions were significantly increased(P<0.01).Compared with model group(3rd cycle),general state of mice in all treatment groups were restored and colonic tissues pathology were improved to some extent.Target proteins and genes expressions in other treatment groups were significantly decreased except for Gehua Jiecheng Decoction low-dose group(P<0.01).Conclusion:Gehua Jiecheng Decoction may destroy tumor inflammatory microenvironment,repair damaged colonic mucosa tissue,delay inflamma-tion-cancer transformation process and prevent UCAC by inhibiting activation of IL-6/JAK2/STAT3 signaling pathway.

Objective:To investigate the epidemiology features, intervention effects and influencing factors of thrombosis in arteriovenous graft (AVG), and to provide reference for optimizing vascular access scheme in hemodialysis patients.Methods:It was a retrospective study. The clinical and follow-up data of patients with AVG constructed in the Blood Purification Center, the First Affiliated Hospital of Zhengzhou University from January 2018 to December 2022 were analyzed. According to whether AVG thrombosis occurred during the follow-up period, they were divided into thrombosis group and non-thrombosis group, and the epidemiology status, influencing factors and patency rates of AVG thrombosis were analyzed. AVG was followed up until June 30, 2023 or abandonment or death of patient or loss of follow-up. Kaplan-Meier method was used to analyze the patency rates of AVG. Log-rank test was used to compare the differences of patency rates between groups. Logistic regression model was used to analyze the influencing factors of AVG thrombosis.Results:The study included 475 AVG from 464 patients, with age of (55.50 ± 11.85) years old, 193 males (40.6%), 185 diabetes patients (38.9%) and dialysis age of 24 (1, 68) months. One hundred and fifty-four AVG (32.4%) had a total of 307 AVG thrombotic events during the follow-up of 602 (380, 920) days, with a standardized incidence of 0.34 times per patient-year. Among them, 60 cases (19.5%, 60/307) had frequent thrombosis. Kaplan-Meier survival analysis showed that AVG secondary patency rates at 2-years and 3-years in the thrombosis group and frequent thrombosis subgroup were inferior to those in the non-thrombosis group (84.0% vs. 92.5%, P=0.017; 66.5% vs. 85.7%, P<0.001; 78.9% vs. 92.5%, P=0.030; 54.6% vs. 85.7%, P<0.001). Two hundred and sixty-nine AVG thrombotic events were analyzed to evaluate the treatment effects. Endovascular interventional surgery was used for thrombectomy in 215 cases (79.9%), and hybrid surgery (endovascular interventional surgery combined with surgical incision) was used in 54 cases (20.1%), with a technical success rate of 98.9% (266/269) and a clinical success rate of 98.1% (264/269). Kaplan-Meier survival analysis showed that there were no statistically significant differences in the primary post-intervention patency rates at 90 days and 365 days, respectively (all P>0.05), and there was statistically significant difference in the primary post-intervention patency rate at 180 days (45.1% vs. 26.5%, Z=2.563, P=0.015). Multivariate logistic regression analysis showed that graft-applied type (intering as the reference, propaten OR=1.953, 95% CI 1.139-3.350, P=0.015; acuseal OR=2.628, 95% CI 1.438-4.800, P=0.002), body mass index < 18.5 kg/m 2 (18.5-24.0 kg/m 2 as the reference, OR=0.291,95% CI 0.090-0.943, P=0.040), serum albumin < 40 g/L ( OR=1.579, 95% CI 1.019-2.445, P=0.041), serum ferritin < 200 μg/L ( OR=1.818, 95% CI 1.162-2.845, P=0.009) and mean arterial pressure < 70 mmHg ( OR=7.180, 95% CI 1.339-38.501, P=0.021) were the independent influencing factors of AVG thrombosis. Conclusions:The incidence of AVG thrombotic events is 0.34 times per patient-year, mainly concentrated in a small number of patients. Thrombosis reduces the secondary patency rate of AVG. AVG thrombosis treatment with endovascular interventional surgery or hybrid surgery has a high technical success rate and a clinical success rate. The thrombosis is related to graft-applied types, nutritional status of patients and mean arterial pressure level.

Objective:To investigate the spatial distribution pattern of local tumor progression (LTP) for hepatocellular carcinoma (HCC) ≤5 cm after microwave ablation.Methods:A retrospective analysis was performed on 169 HCCs with matched MRI before and after ablation from December 2009 to December 2019. A tumor MRI was reconstructed using three-dimensional visualization technology. LTP was classified as contact or non-contact, early or late stage, according to whether LTP was in contact with the edge of the ablation zone and the occurrence time (24 months). The tumor-surrounded area was divided into eight quadrants by using the eight-quadrant map method. An analysis was conducted on the spatial correlation between the quadrant where the ablative margin (AM) safety boundary was located and the quadrant where different types of LTP occurred. The t-test, or rank-sum test, was used for the measurement data. 2-test for count data was used to compare the difference between the two groups.Results:The AM quadrant had a distribution of 54.4% LTP, 64.2% early LTP stage, and 69.1% contact LTP, suggesting this quadrant was much more concentrated than the other quadrants ( P ?

Objective:To evaluate the long-term efficacy of percutaneous microwave ablation (MWA) therapy for hepatocellular carcinoma.Methods:2054 cases with Barcelona Clinic Liver Cancer (BCLC) stage 0~B at the Fifth Medical Center of the Chinese People's Liberation Army General Hospital from January 2006 to September 2020 were retrospectively collected. All patients were followed up for at least 2 years. The primary endpoint of overall survival and secondary endpoints (tumor-related survival, disease-free survival, and postoperative complications) of patients treated with ultrasound-guided percutaneous MWA were analyzed. Kaplan-Meier method was used for stratified survival rate analysis. Fine-and-Gray competing risk model was used to analyze overall survival.Results:A total of 5 503 HCC nodules [mean tumor diameter (2.6±1.6) cm] underwent 3 908 MWAs between January 2006 and September 2020, with a median follow-up time of 45.6 (24.0 -79.2) months.The technical effectiveness rate of 5 375 tumor nodules was 97.5%. The overall survival rates at 5, 10, and 15-years were 61.6%, 38.8%, and 27.0%, respectively. The tumor-specific survival rates were 67.1%, 47.2%, and 37.7%, respectively. The free tumor survival rates were 25.8%, 15.7%, and 9.9%, respectively. The incidence rate of severe complications was 2.8% (108/3 908). Further analysis showed that the technical effectiveness and survival rate over the passing three time periods from January 2006-2010, 2011-2015, and 2016-September 2020 were significantly increased, with P ?

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Rapid and living guidelines are those developed in response to public health emergencies in a short period of time using a scientific and standardized approach. Subsequently， they provide timely and credible recommendations for decision makers through regular and frequent updates of clinical evidence and recommendations. In this paper， we introduced the definition of rapid and living guideline as well as analyzed the basic characteristics of eight rapid and living guidelines in the field of traditional Chinese medicine （TCM） published till 2023 June， summarizing three core methodological issues in relation to how to rapidly develop guidelines， how to formulate recommendations when there is lack of evidence， and how to ensure the timeliness of guidelines. Based on the analysis of current rapid and living guidelines， it is implicated that there is necessity to carry out rapid and living guideline in the field of TCM， and the methodology of rapid integration of multivariate evidence in the field of TCM needs to be further explored； furthermore， it is necessary to further explore the obstacles of implementation of guidelines and promote timely updating， all of which provide certain theoretical references for relevant guideline developers and researchers.

It is necessary to develop rapid and living guidelines in order to improve the evidence translation and guidance for clinical practice in emergency situations， and to enhance the participation of traditional Chinese medicine （TCM） in management of emergencies. This paper introduced the process of developing rapid and living guidelines of TCM and divided it into three stages， that is preparation， rapid development and dynamic updating， which highlights the features of rapid development， high quality， and dynamic updating and the integration with the predominance of TCM. By comparing with general guidelines on composition， personnel number， timing to formulate and communication patterns of the guideline working groups， as well as the content and number of clinical questions， this paper mainly gave suggestions on how to formulate a concise but authoritative team during the preparation stage， how to efficiently manage the guideline team and promote the development process from conflict of interest management， working and communication mode adjustment， and how to formulate and update the important and prioritized clinical questions， all of which may provide reference for the development of TCM rapid and living guidelines.
