Background: s/Aims: Non-invasive models stratifying clinically significant portal hypertension (CSPH) are limited. Herein, we developed a new non-invasive model for predicting CSPH in patients with compensated cirrhosis and investigated whether carvedilol can prevent hepatic decompensation in patients with high-risk CSPH stratified using the new model. Methods: Non-invasive risk factors of CSPH were identified via systematic review and meta-analysis of studies involving patients with hepatic venous pressure gradient (HVPG). A new non-invasive model was validated for various performance aspects in three cohorts, i.e., a multicenter HVPG cohort, a follow-up cohort, and a carvediloltreating cohort. Results: In the meta-analysis with six studies (n=819), liver stiffness measurement and platelet count were identified as independent risk factors for CSPH and were used to develop the new “CSPH risk” model. In the HVPG cohort (n=151), the new model accurately predicted CSPH with cutoff values of 0 and –0.68 for ruling in and out CSPH, respectively. In the follow-up cohort (n=1,102), the cumulative incidences of decompensation events significantly differed using the cutoff values of <–0.68 (low-risk), –0.68 to 0 (medium-risk), and >0 (high-risk). In the carvediloltreated cohort, patients with high-risk CSPH treated with carvedilol (n=81) had lower rates of decompensation events than non-selective beta-blockers untreated patients with high-risk CSPH (n=613 before propensity score matching [PSM], n=162 after PSM). Conclusions Treatment with carvedilol significantly reduces the risk of hepatic decompensation in patients with high-risk CSPH stratified by the new model.

Objective To construct risk prediction models of death or readmission in patients with acute heart failure(AHF)during the vulnerable phase based on machine learning algorithms and screen the optimal model.Methods A total of 651 AHF patients with admitted to Department of Cardiology of the Second Affiliated Hospital of Army Medical University from October 2019 to July 2021 were included.The clinical data consisting of admission vital signs,comorbidities and laboratory results were collected from electronic medical records.The composite endpoint was defined as all-cause death or readmission for worsening heart failure within 3 months after discharge.The patients were divided into a training set(521 patients)and a test set(130 patients)in a ratio of 8:2 through the simple random sampling.Six machine learning models were developed,including logistic regression(LR),random forest(RF),decision tree(DT),light gradient boosting machine(LGBM),extreme gradient boosting(XGBoost)and neural networks(NN).Receiver operating characteristic(ROC)curve and decision curve analysis(DCA)were used to evaluate the predictive performance and clinical benefit of the models.Shapley additive explanation(SHAP)was used to explain and evaluate the effect of different clinical characteristics on the models.Results A total of 651 AHF patients were included,of whom 203 patients(31.2%)died or were readmitted during the vulnerable phase.ROC curve analysis showed that the AUC values of the LR,RF,DT,LGBM,XGBoost and NN model were 0.707,0.756,0.616,0.677,0.768 and 0.681,respectively.The XGBoost model had the highest AUC value.DCA showed that the XGBoost model exhibited greater clinical net benefit compared with other models,with the best predictive performance.SHAP algorithm analysis showed that the clinical features that had the greatest impact on the output of the model were serum uric acid,D-dimer,mean arterial pressure,B-type natriuretic peptide,left atrial diameter,body mass index,and New York Heart Association(NYHA)classification.Conclusion The XGBoost model has the best predictive performance in predicting the risk of death or readmission of AHF patients during the vulnerable phase.

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 establish ultra performance liquid chromatography (UPLC) characteristic chromatogram of Pulsatilla chinensis; To provide reference for the origin identification and quality control of Pulsatilla chinensis. Methods:UPLC Method was adopted. The determination was performed on a column of Agilent SB C18 (2.1 mm×100 mm, 1.8 μm) . The mobile phase was acetonitrile-methanol (2:1) -0.1% phosphoric acid solution by fradient elution at a flow rate of 0.30ml/min. The column temperature was 30 ℃. The detection wavelength was 215 nm. The injection volume was 2 μl. The common counterfeit products and medicinal herbs of Pulsatilla chinensis from different areas were evaluated by comparison of characteristic chromatogram, principal component analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-DA). Results:There were 9 characteristic peaks in the characteristic chromatogram of Pulsatilla chinensis, and 8 common peaks were identified by high resolution mass spectrometry and comparison of reference materials. Through PCA analysis, it was possible to clearly distinguish the medicinal herbs of Pulsatilla chinensis from different areas. Combined with OPLS-DA analysis, it was found that peak 2, peak 3, peak 6 were the main markers of Pulsatilla chinensis from different producing areas. Conclusion:The established method has good specificity, repeatability and durability, and it can effectively distinguish the common counterfeits of Pulsatilla chinensis, and provide the basis of quality control and selection of origin for Pulsatilla chinensis.

Objective:To evaluate the efficacy of individualized removal therapeutic regimen for donor-specific antibodies (DSA) and examine its related influencing factors.Method:From January 2016 to January 2021, 34 recipients of kidney transplant (KT) underwent regular DSA testing and the results were positive. DSA removal therapy based upon rituximab (RTX) plus intravenous immune globulin (IVIG) was offered. Correlation between DSA negative conversion rate and DSA types, time from start of treatment to transplantation, HLA loci targeted by DSA and DSA mean fluorescent intensity (MFI) were analyzed retrospectively. Changes of immunedominant DSA (iDSA) and serum creatinine in individuals with de novo DSA (dnDSA) before and after treatment were also examined.Results:At Month 3 post-treatment, antibodies turned negative in 17/34(50.0%) patients and DSA became negative in 19/34(55.9%) at the last follow-up. Then we identified 78 DSA from all patients. No significant difference existed in negative conversion rate of pfDSA and dnDSA at Month 3 post-treatment [62.9%(39/62) vs 37.5%(6/16)] and at the last follow-up [4.2%(46/62) vs 56.3%(9/16)]( P=0.067, 0.219). For pfDSA, negative conversion rate of pfDSA with different MFIs after 3-month treatment varied significantly [negative conversion rate of weak positive DSA was 78.6%(33/42) and positive and above DSA 30%(6/20), P<0.001]. It was an independent related factor of whether or not pfDSA could turn negative (48.6%, 95% CI: 22.3%-66.8%, P=0.001). At the last follow-up, negative conversion rate of pfDSA differed markedly at different timepoints from start of treatment to transplantation [treated within 30 days post-operation was 79.2%(42/53) and over 30 days post-operation was 44.4%(4/9), P=0.042] and among different DSA MFI [88.1%(37/42) of weakly positive DSA and 45%(9/20) of positive and above DSA, P<0.001] and they were independent related factors for negative conversion of pfDSA (34.8%, 95% CI: 3.2%-61.8%, P=0.008; 43.1%, 95% CI: 18.5%-63.4%, P=0.001). Mean decline rate in iDSA was 66.67% at Month 3 post-treatment and 77.90% at the last follow-up. The difference was statistically significant ( P=0.035). Serum level of creatinine of 9 patients with dnDSA was (110.2±26.9) μmol/L pre-treatment, (178.8±90.5) μmol/L during treatment, (153.9±72.8) μmol/L at Month 3 post-treatment and (213.6±185.8) μmol/L at the last follow-up. Serum creatinine rose during treatment ( t=-2.794, P=0.023), declined at Month 3 post-treatment ( t=3.430, P=0.009) and spiked again at the last follow-up ( P=0.028). Conclusion:After DSA removal therapy based upon RTX plus IVIG, negative conversion rate of pfDSA is correlated with its MFI and time from start of treatment to transplantation. There is no significant rebound in DSA MFI and graft function of dnDSA patients improves immediately after treatment.

OBJECTIVE: To observe the impact of indirect moxibustion with Taiyi moxa stick on pain severity and the quality of life in the patients with back myofascitis, and evaluate its clinical effect and safety. METHODS: Seventy-two patients with back myofascitis were randomly divided into an observation group (36 cases, 1 cases dropped out) and a control group (36 cases, 3 cases dropped out). Three to six ashi points were selected using acupoint diagnosis methods. In the observation group, the indirect moxibustion with Taiyi moxa stick was operated at the ashi points, once every other day, three times a week. In the control group, the topical treatment with diclofenac sodium gel was given at ashi points, three times daily. The treatment was delivered consecutively for 2 weeks in the two groups. The scores of visual analogue scale (VAS) and the short-form McGill pain questionnaire (SF-MPQ) were recorded before treatment, after 1 and 2 weeks of treatment, and after 4 weeks of treatment completion (follow-up visit) in the two groups separately. The difference value between VAS score after 2 weeks of treatment and that before treatment was taken as the primary outcome. The SF-36 score was observed before treatment, after 2 weeks of treatment and during the follow-up visit, and the safety was evaluated in the two groups. RESULTS: The difference value of VAS scores was (-4.57±1.50) points and (-2.40±1.31) points in the observation group and the control group, respectively, the reduction of the score in the observation treatment was larger than that of the control group (P<0.001). After 1 and 2 weeks of treatment and during the follow-up visit, VAS and SF-MPQ scores were reduced when compared with those before treatment (P<0.05) in the two groups, and VAS and SF-MPQ scores in the observation group were lower than those in the control group (P<0.05). In the follow-up visit, VAS and SF-MPQ scores in the observation group were dropped in comparison with those after 1 week of treatment (P<0.05), and these scores in the control group were elevated compared with those after 2 weeks of treatment (P < 0.05). After 2 weeks of treatment and during the follow-up visit, the score of each dimension and total score of SF-36 scale were increased in comparison with those before treatment in the observation group (P<0.05); and the scores of the dimensions except that of mental health of SF-36 scale were elevated in the control group (P<0.05). During the follow-up visit, in the control group, the scores of physical functioning, bodily pain, general health and role emotional were elevated when compared with those before treatment (P<0.05). After 2 weeks of treatment and during the follow-up visit, the score of every dimension and total score of SF-36 scale in the observation group were higher than those in the control group (P<0.05). During the follow-up visit, the score of bodily pain was increased when compared with that after 2 weeks of treatment in the observation group (P<0.05), while the scores of bodily pain and vitality were dropped in the control group (P<0.05). No adverse event happened in the two groups. CONCLUSION The indirect moxibustion with Taiyi moxa stick effectively reduces pain severity and improves the quality of life in the patients with back myofascitis. This therapy presents the superior and persistent effect compared with topical application of diclofenac sodium gel.

Objective:To evaluate a surgical approach for partial resection of the tenth rib through a retroperitoneal approach for the exposure of Crawford type IV thoracoabdominal aortic aneurysm and complex abdominal aortic aneurysm from 2014 to 2019.Methods:A retrospective analysis was conducted on clinical data and follow-up results of 7 patients who underwent treatment for Crawford type IV thoracoabdominal aortic aneurysm and complex abdominal aortic aneurysm through partial resection of the tenth rib via a retroperitoneal approach.Results:One case (14.3%) had associated Marfan syndrome, and 5 cases (71.4%) underwent left renal artery reconstruction. None of the patients experienced severe complications such as cardiopulmonary complications or renal failure postoperatively, and there was no statistically significant difference in serum creatinine levels between preoperative and postoperative stages during hospitalization ( P=0.205). Follow-up examinations showed no long-term vascular stenosis. Conclusions:Partial resection of the tenth rib through a retroperitoneal approach can avoid incisions of the pleura and diaphragm. It allows for the exposure of the aorta below the diaphragm and has the ability to treat aortic diseases below the diaphragm with smaller incisions and lower complication risks.
