‍ ObjectiveTo investigate and compare the value of albumin-related ratios ［total bilirubin-to-albumin ratio （TAR）， creatinine-to-albumin ratio （CAR）， prothrombin time-international normalized ratio-to-albumin ratio （IAR）， neutrophil count-to-albumin ratio （NAR）， and red blood cell distribution width-to-albumin ratio （RAR）］ in predicting the short-term prognosis of patients with hepatitis B virus-related acute-on-chronic liver failure （HBV-ACLF）. MethodsA retrospective analysis was performed for 354 patients with HBV-ACLF who were admitted to Department of Infectious Diseases， The Affiliated Hospital of Southwest Medical University， from June 2017 to February 2022， and according to their prognosis at 3 months of follow-up， they were divided into survival group （n=272） and death group （n=82）. Related indices were recorded for all patients， including age， sex， complications， and the results of routine blood test， liver function， and coagulation for the first time after admission， and albumin-related ratios and Model for End-Stage Liver Disease （MELD） score were calculated. The 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 distribution continuous data between groups； the chi-square test was used for comparison of categorical data between groups. The Spearman correlation test was used to investigate the correlation between albumin-related ratios and MELD score. The Logistic regression analysis was used to explore the association of MELD score， TAR， CAR， IAR， NAR， and RAR with poor prognosis. The area under the ROC curve （AUC） was used to as sess the accuracy of albumin-related ratios and MELD score in predicting the short-term prognosis of HBV-ACLF patients， and the De-Long test was used for the comparison of AUC. ResultsCompared with the death group， the survival group had significantly lower MELD score （Z=-8.071， P<0.001）， TAR （Z=-6.695， P<0.001）， CAR （Z=-4.463， P<0.001）， IAR （Z=-7.912， P<0.001）， NAR （Z=-4.061， P<0.001）， and RAR （Z=-4.788， P<0.001）. MELD score was positively correlated with CAR （r=0.616， P<0.001）， IAR （r=0.733， P<0.001）， TAR （r=0.657， P<0.001）， NAR （r=0.392， P<0.001）， and RAR （r=0.380， P<0.001）. The multivariate regression analysis of MELD score and albumin-related ratios showed that high TAR （odds ratio ［OR］=1.014， 95% confidence interval ［CI］： 1.008 — 1.020， P<0.001） and high IAR （OR=22.052， 95%CI： 6.937 — 70.103， P<0.001） were independent risk factors for death. The ROC curves were plotted for albumin-related ratios and MELD score to evaluate their discriminatory ability for mortality， and the results showed that MELD score， TAR， CAR， IAR， NAR， and RAR had an AUC of 0.794， 0.744， 0.663， 0.788， 0.648， and 0.674， respectively， among which MELD score had the highest sensitivity of 86.59% and CAR had the highest specificity of 77.57%. TAR combined with IAR had an AUC of 0.809， with a sensitivity of 76.8% and a specificity of 71.3%. Subgroup analysis of HBV-ACLF showed that TAR combined with IAR had the highest AUC values of 0.884 and 0.733， respectively， in patients with type A or type C HBV-ACLF. ConclusionTAR and IAR can be used as simple and effective prognostic tools to predict the 90-day mortality of HBV-ACLF patients.

Objective To establish a new model of indocyanine green (ICG) clearance test combined with total bilirubin actual resident rate (TBARR) for predicting the short-term prognosis of patients with hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF) treated with artificial liver support system (ALSS) therapy. Methods A retrospective analysis was performed for the clinical data of 136 patients with HBV-ACLF who underwent ALSS therapy in Department of Infectious Diseases, The Affiliated Hospital of Southwest Medical University, from June 2017 to July 2021, and according to the prognosis at 3-month follow-up, they were divided into survival group with 92 patients and death group with 44 patients. Related indicators were measured at the time of the confirmed diagnosis of ACLF, including biochemical parameters, coagulation, indocyanine green retention rate at 15 minutes (ICGR 15 ), and effective hepatic blood flow (EHBF), and related indices were calculated, including Model for End-Stage Liver Disease (MELD) score, MELD difference (ΔMELD), Child-Turcotte-Pugh (CTP) score, total bilirubin clearance rate (TBCR), total bilirubin rebound rate (TBRR), and TBARR. The Mann-Whitney U test was used for comparison of continuous data with skewed distribution between two groups; the chi-square test was used for comparison of categorical data between groups. A binary logistic regression analysis was used to establish a combined predictive model for the prognosis of HBV-ACLF after ALSS therapy. The area under the ROC curve (AUC) was used to compare the accuracy of various models in judging the short-term prognosis of patients with HBV-ACLF after ALSS therapy, and the Z test was used for comparison of AUC. Results There were significant differences between the death group and the survival group in MELD score, ΔMELD, CTP score, ICGR 15 , EHBF, TBRR, TBARR, neutrophil count, percentage of neutrophils, lymphocyte count, platelet count, alkaline phosphatase, gamma-glutamyl transpeptidase, total bilirubin, albumin, prothrombin time, international normalized ratio, prothrombin time activity, prealbumin, fibrinogen, serum sodium, age, and the incidence rate of hepatic encephalopathy (all P < 0.05). The multivariate logistic regression analysis showed that age (odds ratio [ OR ]=1.096, 95% confidence interval [ CI ]: 1.056-1.137, P < 0.001), neutrophil count ( OR =1.214, 95% CI : 1.044-1.411, P =0.012), TBRR ( OR =0.989, 95% CI : 0.982-0.996, P =0.001), TBARR ( OR =1.073, 95% CI : 1.049-1.098, P < 0.001), ΔMELD ( OR =1.480, 95% CI : 1.288-1.701, P < 0.001), CTP score ( OR =2.081, 95% CI : 1.585-2.732, P < 0.001), and ICGR 15 ( OR =1.116, 95% CI : 1.067-1.168, P < 0.001) were independent influencing factors for short-term mortality in patients with HBV-ACLF after ALSS therapy. The binary logistic regression analysis was used to establish four combined predictive models for predicting the prognosis of HBV-ACLF after ALSS therapy, i.e., TBRR-ICGR 15 , TBARR-ICGR 15 , TBARR-ICGR 15 -ΔMELD, and TBARR-ICGR 15 -ΔMELD-age, with an AUC of 0.830, 0.867, 0.900, and 0.917, respectively, and the combined predictive models had a larger AUC than each index alone (age, neutrophil count, TBRR, TBARR, ΔMELD, MELD score, CTP score, and ICGR 15 ), among which the TBARR-ICGR 15 -ΔMELD-age model had the largest AUC. The combined models TBARR-ICGR 15 -ΔMELD and TBARR-ICGR 15 -ΔMELD-age had sensitivities and specificities of > 80%. Conclusion The combined predictive model established by ICGR 15 and TBARR has a good value for in predicting the short-term prognosis of patients with HBV-ACLF after ALSS therapy, and the combined predictive model has a better accuracy than the single model in judging prognosis.

Building a better performance evaluation system for public hospitals is key to the ongoing health reform. To this end, Beijing Municipal Administration of Hospitals reformed the performance evaluation system of public hospitals in Beijing based on its experiences during 2012 to 2014. This reform integrates the target tasks,day-to-day performance,personalized performance,Party and people management performance,and mandatory plan performance as one evaluation integrity,forming a new public hospitals’performance evaluation system of multi-dimension and multi-level.This approach can effectively integrate diversified performance management objectives and overcome key difficulties in performance management,assisting further promotion of the approach,facilitating government objectives in managing the medical sector,promoting healthy development of hospitals,and exploring how to deepen the public hospital reform in terms of separating ownership from operations.

The role of public hospital performance evaluation has become a roadblock for the current reform of public hospitals.By summarizing the performance evaluation of Beijing municipal hospitals in recent three years,the authors systematically introduced the practice of Beijing Municipal Administration of Hospitals in establishing a public hospital performance evaluation mechanism.In addition,the paper introduced the achievements of the Administration in the evaluation methods of public hospital evaluation,governmental responsibilities in hospital governance,guidance of hospitals’orderly development,and positive interactions between the government and hospitals.This way the paper provided useful references for guiding the hospitals back to public service nature,positive interactions, refined management of hospitals and better performance management.

BACKGROUND: Bone marrow mesenchymal stem cells (BMSCs) can grow in host myocardium, differentiate under myocardial condition, improve cardiac function. However, biological characteristics of BMSC differentiation are still unclear presently.OBJECTIVE: To study the expression and electrophysiological characteristics of BMSC/n vitro connexin-43 following 5-azacitidine (5-aza) treatment.DESIGN, TIME AND SETTING: The cytological in vitro controlled study was perormed at the Heart Center, Hebei Provincial People's Hospital from July 2007 to February 2009.MATERIALS: A total of 24 male pigs aged 2 months were purchased from Exparimental Animal Center, Hebei Medical University.METHODS: Bilateral femoral bone marrow was obtained from pigs under sterile condition. BMSCs were harvested by Percoll density gradient in vitro. At passage 2, BMSCs were treated with 10 μmol/L 5-aza, and incubated in DMeM without inductor 24 hours later. Indices were measured I, 2, 3 weeks following induction. A control group was set up, which was not treated with 5-azacitidine. Following bone marrow extraction, experimental pigs were anesthetized to obtain ventricular muscle. Normal ventricular muscle cells were isolated and cultured by tissue block enzyme digestion method.MAIN OUTCOME MEASURES: Expression of connexin-43 was measured by immunohistochemical staining (ABC method). Ito current density and action potential were determined by patch clamp technique.RESULTS: At 1 and 2 weeks following 5-aza induction, some BMSCs were positive for connexin-43, with the presence of brown particles surrounding nuclei. At 3 weeks, positive rate of connexin-43 was 95%. The area with large cell density was presented with similar structure to normal myocardium. At +80 mV, compared with normal myocardial cells, Ito current density was significantly reduced in BMSCs following 1 and 2 weeks and in the control group (P < 0.05). Ito current density was significantly increased to a normal levels in BMSCs 3 weeks following induction (P > 0.05). No action potential was detected in BMSCs following 1 and 2 weeks of 5-aza, and action potential could be determined 3 weeks following induction, which was identical to normal myocardial cells.CONCLUSION: Through induced by 5-aza for three weeks, BMSCs have the similar expression of connexin-43 and electrophysiological characteristics as normal myocardium.
