ObjectiveTo investigate the clinical features and outcomes of recompensation in patients with autoimmune hepatitis （AIH）-related decompensated cirrhosis， to identify independent predictive factors， and to construct a nomogram prediction model for the probability of recompensation. MethodsA retrospective cohort study was conducted among the adult patients with AIH-related decompensated cirrhosis who were admitted to The Fifth Medical Center of PLA General Hospital from January 2015 to August 2023 （n=211）. The primary endpoint was achievement of recompensation， and the secondary endpoint was liver-related death or liver transplantation. According to the outcome of the patients at the end of the follow-up， the patients were divided into the recompensation group （n=16） and the persistent decompensation group（n=150）.The independent-samples t test was used for comparison of normally distributed continuous data with homogeneity of variance， and the Mann-Whitney U rank sum test was used for comparison of non-normally distributed continuous data with heterogeneity of variance； the chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups； the Kaplan-Meier method was used for survival analysis； the Cox proportional-hazards regression model was used to identify independent predictive factors， and a nomogram model was constructed and validated. ResultsA total of 211 patients were enrolled， with a median age of 55.0 years and a median follow-up time of 44.0 months， and female patients accounted for 87.2%. Among the 211 patients， 61 （with a cumulative proportion of 35.5%） achieved recompensation. Compared with the persistent decompensation group， the recompensation group had significantly higher white blood cell count， platelet count （PLT）， total bilirubin （TBil）， alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， total bile acid， prothrombin time， international normalized ratio （INR）， SMA positive rate， Model for End-Stage Liver Disease （MELD） score， Child-Pugh score， and rate of use of glucocorticoids （all P0.05）， as well as significantly lower age at baseline， number of complications， and death/liver transplantation rate （all P0.05）. At 3 and 12 months after treatment， the recompensation group had continuous improvements in AST， TBil， INR， IgG， MELD score， and Child-Pugh score， which were significantly lower than the values in the persistent decompensation group （all P0.05）， alongside with continuous increases in PLT and albumin， which were significantly higher than the values in the persistent decompensation group （P0.05）. The multivariate Cox regression analysis showed that baseline ALT （hazard ratio ［HR］=1.067， 95% confidence interval ［CI］： 1.010 — 1.127， P=0.021）， IgG （HR=0.463，95%CI：0.258 — 0.833， P=0.010）， SMA positivity （HR=3.122，95%CI：1.768 — 5.515， P0.001）， and glucocorticoid therapy （HR=20.651，95%CI：8.744 — 48.770， P0.001） were independent predictive factors for recompensation， and the nomogram model based on these predictive factors showed excellent predictive performance （C-index=0.87，95%CI：0.84 — 0.90）. ConclusionAchieving recompensation significantly improves clinical outcomes in patients with AIH-related decompensated cirrhosis. Baseline SMA positivity， a high level of ALT， a low level of IgG， and corticosteroid therapy are independent predictive factors for recompensation. The predictive model constructed based on these factors can provide a basis for decision-making in individualized clinical management.

Objective To investigate the expression of kinesin family member 23(KIF23)in rectal cancer and its association with prognosis.Methods This study included 90 patients with rectal cancer who underwent surgical treatment at the First Central Hospital of Baoding from May 2017 to October 2019.Immunohistochemical staining was used to detect KIF23 expression,and the results were analyzed in combination with clinical and pathological data.Survival analysis was conducted using Kaplan-Meier methods and Cox proportional hazards models to assess the association between KIF23 expression and patient prognosis.Results Compared with adjacent non-tumor tis-sues,the expression level of KIF23 protein was significantly higher in rectal cancer tissues.Positive expression of KIF23 was significantly correlated with TNM stage,lymph node metastasis and distant metastasis in rectal cancer patients(P＜0.05).Kaplan-Meier analysis revealed that individuals expressing high levels of KIF23 experienced notably diminished disease-free survival(DFS)and overall survival(OS)relative to those with low KIF23 expression(P＜0.05).Cox regression analysis revealed that advanced TNM stage,lymph node metastasis,distant metastasis,and elevated KIF23 expression served as an independent predictor of adverse outcomes in pa-tients with rectal cancer(P＜0.05).Conclusions The expression level of KIF23 is closely related to the prognosis of rectal cancer.

Pathology is the gold standard for diagnosis of neoplastic diseases.Whole slide imaging turns traditional slides into digital images,and artificial intelligence has shown great potential in pathological image analysis,especially deep learning models.The application of artificial intelligence in whole slide imaging of lung cancer involves many aspects such as histopathological classification,tumor microenvironment analysis,efficacy and survival prediction,etc.,which is expected to assist clinical decision-making of accurate treatment.Limitations in this field include the lack of precisely annotated data and slide quality varying among institutions.Here we summarized recent research in lung cancer pathology image analysis leveraging artificial intelligence and proposed several future directions.

Objective To discuss the clinical safety,feasibility and efficacy of transcatheter arterial infusion chemotherapy(TAI)combined with lipiodol chemoembolization in the treatment of advanced colorectal cancer(CRC).Methods The clinical data of 37 patients with advanced CRC,who received TAI combined with lipiodol chemoembolization at the First Affiliated Hospital of Zhengzhou University of China between June 2016 and December 2022,were retrospectively analyzed.The clinical efficacy was evaluated,the progression-free survival(PFS)and the serious complications were recorded.Results A total of 55 times of TAI combined with lipiodol chemoembolization procedures were successfully accomplished in the 37 patients.The mean used amount of lipiodol emulsion was 2.9 mL(0.8-10 mL).No serious complications such as bleeding and intestinal perforation occurred.The median follow-up time was 24 months(range of 3-48 months).The postoperative one-month,3-month,6-month and 12-month objective remission rates(ORR)were 67.6%(25/37),67.6%(25/37),64.9%(24/37)and 56.8%(21/37)respectively,and the postoperative one-month,3-month,6-month and 12-month disease control rates(DCR)were 91.9%(34/37),91.9%(34/37),89.2%(33/37)and 81.1%(30/37)respectively.The median PFS was 16 months(range of 2-47 months).As of the last follow-up,22 patients survived and 15 patients died of terminal stage of tumor.Conclusion Preliminary results of this study indicate that TAI combined with lipiodol chemoembolization is clinically safe and effective for advanced CRC,and it provide a new therapeutic method for patients with advanced CRC.

Objective:To investigate the current situation of the use of transjugular intrahepatic portosystemic shunt (TIPS) for portal hypertension, which should aid the development of TIPS in China.Methods:The China Portal Hypertension Alliance (CHESS) initiated this study that comprehensively investigated the basic situation of TIPS for portal hypertension in China through network research. The survey included the following: the number of surgical cases, main indications, the development of Early-TIPS, TIPS for portal vein cavernous transformation, collateral circulation embolization, intraoperative portal pressure gradient measurement, commonly used stent types, conventional anticoagulation and time, postoperative follow-up, obstacles, and the application of domestic instruments.Results:According to the survey, a total of 13 527 TIPS operations were carried out in 545 hospitals participating in the survey in 2021, and 94.1% of the hospital had the habit of routine follow-up after TIPS. Most hospitals believed that the main indications of TIPS were the control of acute bleeding (42.6%) and the prevention of rebleeding (40.7%). 48.1% of the teams carried out early or priority TIPS, 53.0% of the teams carried out TIPS for the cavernous transformation of the portal vein, and 81.0% chose routine embolization of collateral circulation during operation. Most of them used coils and biological glue as embolic materials, and 78.5% of the team routinely performed intraoperative portal pressure gradient measurements. In selecting TIPS stents, 57.1% of the hospitals woulel choose Viator-specific stents, 57.2% woulel choose conventional anticoagulation after TIPS, and the duration of anticoagulation was between 3-6 months (55.4%). The limitation of TIPS surgery was mainly due to cost (72.3%) and insufficient understanding of doctors in related departments (77.4%). Most teams accepted the domestic instruments used in TIPS (92.7%).Conclusions:This survey shows that TIPS treatment is an essential part of treating portal hypertension in China. The total number of TIPS cases is far from that of patients with portal hypertension. In the future, it is still necessary to popularize TIPS technology and further standardize surgical indications, routine operations, and instrument application.

Background::Breast cancer is ranked among the most prevalent malignancies in the Chinese female population. However, comprehensive reports detailing the latest epidemiological data and attributable disease burden have not been extensively documented.Methods::In 2018, high-quality cancer surveillance data were recorded in 700 population-based cancer registries in China. We extracted data on female breast cancers (International Classification of Diseases, Tenth Revision [ICD-10]: C50) and estimated the incidence and mortality in 2022 according to the baseline data and corresponding trends from 2010 to 2018. Pathological types were classified according to the ICD for Oncology, 3rd Edition codes. Disability-adjusted life years (DALYs) were calculated as the sum of the years of life lost (YLLs) and years lived with disability (YLDs).Results::In 2022, approximately 357,200 new female breast cancer cases and 75,000 deaths occurred in China, accounting for 15.59% and 7.94% of total new cancer cases and deaths, respectively. The age-standardized incidence rate (ASIR) was 33.04 per 100,000. When analyzed by pathological type, the ASIRs for papillary neoplasms, invasive breast carcinoma, rare and salivary gland-type tumors, and other types were 1.13, 29.79, 0.24, and 1.88 per 100,000, respectively. The age-standardized mortality rate (ASMR) was 6.10 per 100,000. A total of 2,628,000 DALYs were found to be attributable to female breast cancer in China, comprising 2,278,300 YLLs and 349,700 YLDs. The ASIR, ASMR, and age-standardized rate (ASR) for DALYs in urban areas were consistently higher than those in rural areas. We observed a four-fold increase in the ASIR and ASR for DALYs and an eight-fold increase in the ASMR among females over 55 years compared with those aged under 55 years.Conclusion::These data provide invaluable insights into the latest epidemiology of female breast cancer in China and highlight the urgency for disease prevention and control strategy formulation.

Objective To investigate the efficacy and safety of interventional therapy for bronchopleural fistula(BPF).Methods A total of 172 patients with confirmed BPF were treated with continuous negative pressure drainage(CNPD)and/or airway stent occlusion therapy.The clinical data were collected,and its effectiveness and safety were analyzed.Results In 5-7 days after interventional treatment,the pneumonia severity index(PSI)decreased significantly,and successful drainage was achieved in 166 patients(96.5％).One month after interventional therapy,the lung volume was remarkably increased.The median clinical healing time of interventional therapy was 9.0 months(95％CI=6.18-1 1.83).Multivariate analysis of the Cox proportional hazards model showed that the diagnosis time(HR=0.53,95％CI=0.38-0.74,P＜0.01)and fistula size(HR=0.74,95％CI=0.55-0.99,P=0.04)were significantly correlated with the clinical healing time.Conclusion For the treatment of BPF,CNPD and/or airway stent occlusion has several advantages such as accurate operation,minimally invasive,safe and effective.It can quickly improve the symptoms and quality of life,and prolong survival,therefore,it is worthy of clinical promotion and application.(J Intervent Radiol,2024,33:641-645)

Objective To investigate the application value of the quantitative parameters of collateral circulation based on computed tomography perfusion(CTP)in evaluating the clinical prognosis of patients with acute ischemic stroke(AIS).Methods A total of 126 patients with AIS caused by middle cerebral artery occlusion were enrolled,collateral circulation were reconstructed and scored via multiphase computed tomography angiography(mCTA)based on CTP.The hypoperfusion intensity ratio(HIR)and collateral vessel density(CVD)were calculated.All patients were divided into good prognosis group(72 cases)and poor prognosis group(54 cases)based on 90 d modified Rankin scale(mRS)scores.Differences in cardiovascular risk factors,National Institutes of Health Stroke Scale(NIHSS)scores,Albert stroke program early CT(ASPECT)scores,Tmax＞10 s volume,Tmax＞6 s volume,core infarct area volume,and final infarct volume between the two groups were compared.Binary logistic regression was employed to identify independent predictors of the clinical prognosis,and the DeLong test was used to compare the efficacy of different predictors in predicting clinical prognosis.Results The good prognosis group had significantly higher ASPECT scores,mCTA scores,and CVD,but significantly lower HIR,Tmax＞10 s volume,and baseline NIHSS scores compared to the poor prognosis group(P＜0.05).Binary logistic regression analysis showed that ASPECT scores[odds ratio(OR)=0.780],mCTA scores(OR=0.669),CVD(OR=0.595),and HIR(OR=28.968)were independent predictors of clinical prognosis(P＜0.05).DeLong test found no significant difference in area under the curve(AUC)values between mCTA scores,CVD and HIR in predicting the clinical prognosis of AIS patients(P＞0.05).Conclusion Quantitative parameters such as CVD and HIR related to collateral circulation have a strong diagnostic efficacy in predicting the 90 d clinical prognosis in patients with AIS.

From February 1 to April 30, 2021, 48 general practice resident physicians in the First Affiliated Hospital of Naval Medical University were randomly divided into study group and control group with 24 in each group. The common comorbidities of the community-dwelling elderly, namely diabetes, diabetic retinopathy and osteoporosis were selected as teaching cases. The residents in control group received conventional teaching, while the scenario simulation teaching model of multicomorbity co-treatment was applied for the study group. The teaching effect, satisfaction and self-efficacy scores were compared between two groups. After training, the knowledge levels, the mastery of referral indicators and the performance of fundus ophthalmoscopy in the study group were significantly better than those in the control group ( t=2.27, 6.34, 4.09; P<0.05). They were (80.96±11.27) vs. (73.96±10.09), (10.33±2.41) vs. (6.38±1.88), (70.27±10.44) vs. (63.50±7.98), and students′ satisfaction and self-efficacy evaluation were higher than those of the observation group (all P<0.05). It is suggested that the simulation teaching of multi-disease co-treatment scenario is more beneficial than the traditional teaching to improve the comprehensive care ability of standardized training physicians in general practice for patients with chronic disease.

Objective:To explore the effect and value of the active learning mode based on mind mapping in the teaching of medical service support for major disasters.Methods:A total of 90 undergraduate students of 2016 Clinical Medicine of Naval Medical University were randomly selected as research objects, and they were randomly divided into observation group and control group. The 45 students in the control group used the traditional teaching mode, and the 45 students in the observation group used the mind mapping-based active learning mode for major disaster rescue and medical survice. The teaching time of the two groups was 12 h. The theoretical examination of knowledge and practical skills of the two groups of students were compared after teaching, and the students' satisfaction with the application of mind mapping-based teaching model in the teaching of medical service support for major disaster rescue was investigated. EmpowerStats and R softwares were used for t test and Chi-square test. Results:There were 24 males and 21 females in the observation group, with an average age of (21.40±0.69) years old. There were 22 males and 23 females, with an average age of (21.71±0.55) years old. The theoretical performance of the observation group (91.38±4.37) was significantly higher than that of the control group (84.91±3.98) ( P<0.001), and the practical skill performance of the observation group (92.98±3.24) was significantly higher than that of the control group (87.38±3.80) ( P<0.001). At the same time, the students' satisfaction with teaching effect in the observation group was 82.2% (37/45), which was significantly higher than that in the control group (37.8%, 17/45). Conclusion:The active learning mode based on mind mapping focuses on cultivating students' independent learning, interactive exploration and clinical thinking ability, and has a broad application prospect in the teaching of medical service support for major disasters.
