ObjectiveTo investigate the value of different noninvasive diagnostic models in the diagnosis of esophageal and gastric varices since there is a high risk of esophageal and gastric varices in patients with compensated hepatitis B cirrhosis and significant portal hypertension， and to provide a basis for the early diagnosis of esophageal and gastric varices. MethodsA total of 108 patients with significant portal hypertension due to compensated hepatitis B cirrhosis who attended Guangdong Provincial Hospital of Traditional Chinese Medicine from November 2017 to November 2023 were enrolled， and according to the presence or absence of esophageal and gastric varices under gastroscopy， they were divided into esophageal and gastric varices group （GOV group） and non-esophageal and gastric varices group （NGOV group）. Related data were collected， including age， sex， imaging findings， and laboratory markers. The chi-square test was used for comparison of categorical data between groups； the least significant difference t-test was used for comparison of normally distributed continuous data between groups， and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups. The receiver operating characteristic （ROC） curve was plotted to evaluate the diagnostic value of five scoring models， i.e.， fibrosis-4 （FIB-4）， LOK index， LPRI， aspartate aminotransferase-to-platelet ratio index （APRI）， and aspartate aminotransferase/alanine aminotransferase ratio （AAR）. The binary logistic regression method was used to establish a combined model， and the area under the ROC curve （AUC） was compared between the combined model and each scoring model used alone. The Delong test was used to compare the AUC value between any two noninvasive diagnostic models. ResultsThere were 55 patients in the GOV group and 53 patients in the NGOV group. Compared with the NGOV group， the GOV group had a significantly higher age （52.64±1.44 years vs 47.96±1.68 years， t=0.453， P<0.05） and significantly lower levels of alanine aminotransferase ［42.00 （24.00 — 17.00） U/L vs 82.00 （46.00 — 271.00） U/L， Z=-3.065， P<0.05］， aspartate aminotransferase ［44.00 （32.00 — 96.00） U/L vs 62.00 （42.50 — 154.50） U/L，Z=-2.351， P<0.05］， and platelet count ［100.00 （69.00 — 120.00）×10⁹/L vs 119.00 （108.50 — 140.50）×10⁹/L， Z=-3.667， P<0.05］. The ROC curve analysis showed that FIB-4， LOK index， LPRI， and AAR used alone had an accuracy of 0.667， 0.681， 0.730， and 0.639， respectively， in the diagnosis of esophageal and gastric varices （all P<0.05）， and the positive diagnostic rates of GOV were 69.97%， 65.28%， 67.33%， and 58.86%， respectively， with no significant differences in AUC values （all P>0.05）， while APRI used alone had no diagnostic value （P>0.05）. A combined model （LAF） was established based on the binary logistic regression analysis and had an AUC of 0.805 and a positive diagnostic rate of GOV of 75.80%， with a significantly higher AUC than FIB-4， LOK index， LPRI， and AAR used alone （Z=-2.773，-2.479，-2.206， and-2.672， all P<0.05）. ConclusionFIB-4， LOK index， LPRI， and AAR have a similar diagnostic value for esophageal and gastric varices in patients with compensated hepatitis B cirrhosis and significant portal hypertension， and APRI alone has no diagnostic value. The combined model LAF had the best diagnostic efficacy， which provides a certain reference for clinical promotion and application.

Objective To investigate the correlation between serum homeodomain interacting protein ki-nase 2(HIPK2),annexin A5(ANXA5)and coronary stenosis and prognosis in patients with acute myocardial infarction(AMI).Methods A total of 277 AMI patients who received interventional treatment in this hospi-tal from January 2021 to July 2023 were selected as the AMI group,and another 140 cases with normal or very mild stenosis in coronary angiography during the same period were selected as the control group.According to the degree of coronary artery stenosis(Gensini score),the AMI patients were divided into mild coronary arter-y stenosis group(86 cases),moderate coronary artery disease group(111 cases)and severe coronary artery disease group(80 cases).According to the prognosis,they were divided into poor prognosis group(80 cases)and good prognosis group(197 cases).Enzyme-linked immunosorbent assay was used to detect the serum HIPK2 and ANXA5 levels.Spearman correlation analysis was used to analyze the correlation between serum HIPK2 and ANXA5 levels and Gensini score in patients with AMI.Multivariate unconditional Logistic regres-sion was used to determine the relationship between serum HIPK2 and ANXA5 levels and prognosis of AMI patients.Receiver operating characteristic(ROC)curve was used to analyze the predictive efficiency of serum HIPK2 and ANXA5 levels on prognosis of AMI patients.Results Compared with the control group,the ser-um HIPK2 level in the AMI group increased and the ANXA5 level decreased,and the differences were statisti-cally significant(P＜0.05).The serum HIPK2 levels in the mild coronary artery stenosis group,moderate coronary artery stenosis group and severe coronary artery stenosis group increased successively,while the ANXA5 levels decreased successively,and the differences were statistically significant(P＜0.05).Gensini score was positively correlated with serum HIPK2 level and negatively correlated with serum ANXA5 level in AMI patients(P＜0.05).The Gensini score of AMI patients was positively correlated with the serum HIPK2 level(r=0.785,P＜0.05),and negatively correlated with the serum ANXA5 level(r=-0.798,P＜0.05).Compared with the good prognosis group,the serum HIPK2 level in the poor prognosis group increased(P＜0.05),and the ANXA5 level decreased(P＜0.05).After adjusting for confounding factors,high HIPK2 was an independent risk factor for poor prognosis in AMI patients(P＜0.05),and high ANXA5 was an independ-ent protective factor(P＜0.05).The area under the curve of the combined prediction of serum HIPK2 and ANXA5 levels for the prognosis of AMI patients was 0.875,which was greater than 0.778 and 0.784 predic-ted by serum HIPK2 and ANXA5 levels alone(P＜0.05).Conclusion The serum HIPK2 level is increased and the ANXA5 level is decreased in patients with AMI,which is related to the aggravation of coronary steno-sis and the poor prognosis.The combination of serum HIPK2 and ANXA5 levels is more effective in predic-ting the prognosis of patients with AMI.

BACKGROUND: Preclinical studies have indicated that Angong Niuhuang Pills (ANP) reduce cerebral infarct and edema volumes. This study aimed to investigate whether ANP safely reduces cerebral infarct and edema volumes in patients with moderate to severe acute ischemic stroke. METHODS: This randomized, double-blind, placebo-controlled pilot trial included patients with acute ischemic stroke with National Institutes of Health Stroke Scale (NIHSS) scores ranging from 10 to 20 in 17 centers in China between April 2021 and July 2022. Patients were allocated within 36 h after onset via block randomization to receive ANP or placebo (3 g/day for 5 days). The primary outcomes were changes in cerebral infarct and edema volumes after 14 days of treatment. The primary safety outcome was severe adverse events (SAEs) for 90 days. RESULTS: There were 57 and 60 patients finally included in the ANP and placebo groups, respectively for modified intention-to-treat analysis. The median age was 66.0 years, and the median NIHSS score at baseline was 12.0. The changes in cerebral infarct volume at day 14 were 0.3 mL and 0.4 mL in the ANP and placebo groups, respectively (median difference: -7.1 mL; interquartile range [IQR]: -18.3 to 2.3 mL, P = 0.30). The changes in cerebral edema volume of the ANP and placebo groups on day 14 were 11.4 mL and 4.0 mL, respectively ( median difference: 3.0 mL, IQR: -1.3 to 9.9 mL, P = 0.15). The rates of SAE within 90 days were similar in the ANP (3/57, 5%) and placebo (7/60, 12%) groups ( P = 0.36). Changes in serum mercury and arsenic concentrations were comparable. In patients with large artery atherosclerosis, ANP reduced the cerebral infarct volume at 14 days (median difference: -12.3 mL; IQR: -27.7 to -0.3 mL, P = 0.03). CONCLUSIONS: ANP showed a similar safety profile to placebo and non-significant tendency to reduce cerebral infarct volume in patients with moderate-to-severe stroke. Further studies are warranted to assess the efficacy of ANP in reducing cerebral infarcts and improving clinical prognosis. TRAIL REGISTRATION Clinicaltrials.gov , No. NCT04475328.

Objective Focusing on gynecological surgery,we constructed a prediction model for surgical duration by extracting features from unstructured surgical planning texts and integrating multimodal data via artificial intelligence technology.Methods The clinical data of 34 614 patients who underwent gynecologic surgeries at West China Second University Hospital,Sichuan University between January 2022 and October 2024 were collected.An embedding-transformer model was constructed to convert surgical planning texts into a one-dimensional numerical feature,referred to as the step feature.The predictive value of the step feature was assessed by comparing the performance improvements of linear regression,random forest,eXtreme Gradient Boosting(XGBoost),support vector regression,K-nearest neighbor regression,and artificial neural network algorithms in two scenarios—with and without the step feature as an input.The out-of-sample prediction accuracy of the models was assessed using mean absolute error(MAE),root mean squared error(RMSE),and R-squared(R2).Furthermore,the model interpretability was examined using SHapley Additive exPlanations(SHAP)values.Results SHAP results showed that the step feature had the highest predictive contribution.Temporal factors in surgical scheduling also influenced gynecological surgery duration.The XGBoost model demonstrated optimal performance on the test set,significantly improving prediction accuracy with a 40.43%increase in R2,while reducing MAE and RMSE by 21.27%and 20.13%,respectively,compared to the baseline model without the step feature.Conclusion The embedding-transformer model developed in this study effectively extracts features from surgical planning texts and enhances the predictive performance of machine learning models.The XGBoost prediction model can assist hospital administrators in implementing more refined management of gynecological surgeries and improving the utilization efficiency of surgical resources.

Purpose To observation the relationship be-tween the β-catenin/Slug signal specific inhibitor FH535 and EMT,and to explore the role of LPCAT1 in regulating the inva-sion,metastasis,and growth of cervical cancer cells.Methods Hela cells were transfected with sh-NC and sh-LPCAT1,and SiHa cells were transfected with Vector group and LPCAT1 over-expression plasmid.SiHa cells were divided into control group(Con),LPCAT1 group,LPCAT1+FH535 group and FH535 group.The proliferation of cervical cancer cells was detected by CCK-8 analysis and colony formation test.The metastasis and invasion ability of cervical cancer cells were detected by wound healing test and Transwell test.Western blot was used to analyze the expression of LPCAT1,β-catenin/Slug signaling pathway and EMT-related proteins in cells.Results Compared with Vector group,the cell viability,colony number,migration and invasion number of SiHa cells in LPCAT1 group increased signif-icantly(P＜0.05).Compared with sh-NC group,the cell via-bility,colony number,migration and invasion number of Hela cells in sh-LPCAT1 group decreased significantly(P＜0.05).Compared with LPCAT1 group,the levels of Wnt4(1.18±0.05 vs 0.80±0.06),β-catenin(1.05±0.08 vs 0.77±0.05),Slug(1.13±0.06 vs 0.28±0.02),Cyclin D1(0.99±0.06 vs 0.44±0.02),N-cadherin(0.91±0.07 vs 0.46±0.03)and vimentin(0.95±0.06 vs 0.49±0.03)in SiHa cells in LPCAT1+FH535 group decreased significantly(P＜0.05),and the level of E-cadherin(0.44±0.03 vs 0.58±0.03)in-creased significantly(P＜0.05).In addition,compared with LPCAT1 group,the number of colonies(224±15 vs 146±11),migration(85±3vs51±4)and invasive(166±10 vs 90±5)cells of SiHa cells in LPCAT1+FH535 group decreased signifi-cantly(P＜0.05).Conclusion The increase of LPCAT1 ex-pression may promote the metastasis and progress of CC by acti-vating β-catenin/Slug signaling pathway,and LPCAT1 may be a potential marker for predicting CC metastasis.

Objective:To investigate the changes and associated factors of cerebral blood flow in middle-aged and elderly patients undergoing maintenance hemodialysis (MHD).Methods:This was a prospective observational study. End-stage renal disease (ESRD) patients undergoing MHD aged over 50 years at Beijing Shijitan Hospital, Capital Medical University from January 2023 to June 2023 were included. General clinical data of the selected individuals were collected, and dialysis related indicators were recorded and calculated. Mean flow velocity (MFV) of the middle cerebral arterial was measured by transcranial Doppler sonography (TCD) to represent cerebral blood flow throughout dialysis. Hemodialysis-related variables were collected. The MFV values of bilateral middle cerebral artery were measured through temporal windows at 7 time points: 15 minutes before dialysis (T1), 15 minutes (T2), 30 minutes (T3), 60 minutes (T4), 120 minutes (T5), 180 minutes (T6) during dialysis, and the endpoint of dialysis (T7), and the average values were recorded. The ΔMFV was calculated as pre-minus endpoint values of MFV. The Spearman rank correlation method was used to analyze the correlations between ΔMFV and dialysis-related variables, and multiple linear regression method was used to analyze the related factors of the changes in MFV.Results:This study included a total of 123 patients undergoing MHD, aged (63.63±8.44) years (range 50-85 years), including 99 males (80.5%). TCD examination demonstrated a decline trend in MFV throughout dialysis. The MFV at T7 was significantly lower than that at T1 ( Z=-7.650, P<0.001). The Spearman correlation analysis showed that the decline in MFV was correlated with ultrafiltration volume ( r=0.356), ultrafiltration rate ( r=0.371), the difference in systolic pressure (pre-analysis minus post-dialysis, r=0.251), the difference in mean arterial pressure (pre-dialysis minus post-dialysis, r=0.194), combined diabetes ( r=0.293), dialysis vintage ( r=0.220), Kt/V ( r=0.287), and serum albumin ( r=-0.295). Multiple linear regression analysis showed that combined with diabetes ( B=3.889, 95% CI 1.373-6.405, P=0.003), decreased serum albumin ( B=-0.456, 95% CI -0.877--0.036, P=0.034), increased ultrafiltration rate ( B=11.099, 95% CI 6.402-15.797, P<0.001) and the decline in systolic pressure ( B=0.062, 95% CI 0.008-0.116, P=0.026) were significantly associated with the decline in MFV throughout dialysis. Conclusions:In middle and elderly patients with ESRD undergoing hemodialysis, there is a decline trend in cerebral blood flow during hemodialysis. The combination of diabetes, lower serum albumin, higher ultrafiltration rate, and intradialytic systolic pressure decline are the risk factors influencing the intradialytic decline of cerebral blood flow.

Objective To explore the clinical features,imaging and pathological characteristics of the patients with congenital liver fibrosis(CHF).Methods The medical case data of 6 patients with pathological-ly diagnosed CHF in this hospital from January 2011 to June 2021 were retrospectively analyzed,and the clini-cal menifastations,laboratory indicators,imaging characteristics,pathological manifestations,treatment and outcomes were summarized.Results The clinical classification in 6 cases of CHF was mainly portal hyperten-sion(66.67％),and the most common clinical manifestations and signs were hepatosplenomegaly(83.33％),melena(50.00％)and abdominal distension(33.33％).Total bil irubin was normal,and only 2 cases(33.33％)were mildly elevated.The prothrombin time was in the normal range in 4 cases(66.67％),and mild abnormality in 2 cases(33.33％).Imaging showed abnormal liver morphology in 6 cases,spleen enlarge-ment in 5 cases(83.33％),portal vein widening in 3 cases(50.00％),diffuse dilatation of intrahepatic bile ducts in 2 cases(33.33％),and complicating Caroli disease in 1 case(16.67％).The pathological manifesta-tions were normal liver parenchymal cells,periportal fibrosis,and manifold-manifold bridging-like fibrosis.Six cases received the conventional liver protection therapy,3 cases underwent splenectomy+pericardia vascular dissection,the median follow-up time was 68.2 months,1 case died due to liver failure,and 5 cases were rela-tively stable.Conclusion The patients with hepatic disease whose portal hypertension is inconsistent to the degree of hepatic function damage,especially those complicating polycystic kidney disease should perfect the liver puncture pathological examination and genetic testing to clarify the diagnosis,and conduct the genetic counseling and intervention treatment as soon as possible.

Objective To explore the relationship between hyperkalemia and adverse outcomes in elderly maintenance hemodialysis(MHD)patients.Methods A retrospective cohort trial was conducted on 177 MHD patients aged≥60 years in the hemodialysis center of Beijing Shijitan Hospital,Capital Medical University.Baseline data were collected.The mean age was(77.28±14.25)years,among them 109 cases were males(61.6%).According to the peak serum potassium within 4 months,patients were divided into the K+＜5.0 mmol/L group(38 cases,21.5%),the 5.0-5.5 mmol/L group(42 cases,23.7%)and the K+≥5.5 mmol/L group(97 cases,54.8%).Based on the frequency of hyperkalemia within 4 months,patients were divided into the 0,1-2 and 3-4 frequency groups.All of patients were followed up for 1 year.The end point events were all-cause mortality and cardiovascular disease(CVD)mortality.Kaplan-Meier survival analysis was used to compare the cumulative survival rate between the 3 groups.A multivariate Cox regression model was employed to analyze the relationship between the degree and frequency of hyperkalemia with all-cause and CVD mortality.Results The mean follow-up time of 177 patients was 12(1-12)months,20(11.3%)patients died of all-cause death and 14(7.9%)of CVD death.Kaplan Meier survival curve showed cardiovascular mortality rate and all-cause mortality were significantly increased in the K+5.0-5.5 mmol/L group and the K+≥5.5 mmol/L group(both P＜0.05).Multivariate Cox regression analysis indicated that,as a continuous variable,peak potassium levels were independently associated with an increased risk of all-cause death and CVD death(P＜0.001).As a categorical variable,the all-cause mortality risk and CVD mortality risk were significantly higher in both the K+5.0-5.5 mmol/L group and the K+≥5.5 mmol/L group than those in the K+＜5.0 mmol/L group(P＜0.05),and those were significantly higher in the 1-2 and 3-4 frequency groups than those in the 0 frequency group of hyperkalemia(P＜0.05).Conclusion Serum potassium>5.0 mmol/L in elderly MHD patients is an independent risk factor for all-cause and CVD mortality.It is recommended to adjust the upper limit of the normal range of serum potassium to 5.0 mmol/L.

Objective:To understand the incidence and spatial-temporal distribution characteristics of hepatitis B among residents in a county of western Liaoning province from Jan 2011 to Dec 2021.Methods:Data on hepatitis B incidence were obtained from the Disease Prevention and Control Center of the county,and its crude incidence and standardized incidence were calculated.ArcGIS software was used to analyze the global spatial autocorrelation analysis and local spatial autocorrelation analysis of hepatitis B incidence in the county.A space-time scan analysis was performed using SaTScan software to identify the case distribution and spatiotemporal clustering patterns of hepatitis B incidence.Results:From Jan 2011 to Dec 2021,there were 2 978 cumulative cases of hepatitis B in the county,with a crude incidence of 69.25 per 100 000 and a standardized incidence of 70.13 per 100 000.Among different regions,Toutai Manchu Town had the highest crude incidence of hepatitis B,followed by Gaotaizi Town and Chengguan Street.The global autocorrelation showed an aggregated distribution in 2014,2016,2019,and 2021.The local autocorrelation hotspots were clustered in the central and western parts of the county,the H-H clustering areas included Toutai Manchu Town and Jiudaoling Town from 2014 to 2016,Toudaohe Manchu Town,Yizhou Street and Chengguan Street from 2017 to 2019,and Qianyang Town and Yizhou Street from 2020 to 2021.The L-L clustering areas were mostly concentrated in the southwest of the county,including Dizangsi Manchu Township,Dadingbao Manchu Township and Liulonggou Manchu Township.A total of 4 clustering areas were obtained by temporal-spatial scanning analysis,the first-level area was Zhangjiapu Township in 2017,the second-level area included Qianyang Town and Chengguan Street from 2011 to 2015,the third-level area was Gaotaizi Town from 2013 to 2016,and the fourth-level area was Toutai Manchu Town from 2014 to 2017.Conclusions:From Jan 2011 to Dec 2021,the incidence of hepatitis B among residents in a county in western Liaoning Province is mainly concentrated in the central and northwest regions.The hepatitis B cases are clustered in the central and western areas of the county,and has a trend of gradually spreading to the northern areas over time.It is necessary to pay attention to the townships with high incidence of hepatitis B and carry out effective prevention and surveillance.
