Objective:In order to develop a comprehensive hospital debt risk model,it is imperative to conduct an analysis of the present debt risk landscape within public hospitals,so as to furnish hospitals with recommendations to avert potential debt risks.Methods:A debt risk model was constructed based on 7 common factors through the extraction and standardization of data from 25 indicators,using 600 public hospitals in a specific province as samples,followed by factor analysis.Results:The model's calculation of the comprehensive score of public hospitals aligns with professional explanations and provides a more accurate representation of the factors influencing the debt risk level of public hospitals,such as financial investment level,hospital type,hierarchy,and others.Conclusion:In conclusion,the model is efficient.It is imperative to adopt a comprehensive perspective on the matter of hospital debt and efficiently address the associated financial risks faced by public hospitals by fostering collaboration among multiple stakeholders and upholding fundamental principles.

Incidence of twin pregnancies increases significantly in recent years. Twin pregnancies are likely to have a higher risk of quicker progression and more severe preeclampsia (PE) than singletons, making the prediction and prevention of PE of twin pregnancies even more important. The prediction and screening for PE have evolved from guideline-based risk factor screening to simple models with maternal factors only, and then to complex models with a wider range of indicators. Besides, the modeling algorithms have expanded from logistic regression to complex algorithms such as competing risk models. Continuous improvements have been achieved in the prediction models. This paper presents a comprehensive overview of the applicability and the prospect of these models in this area in twin pregnancies and suggests that the prediction models should be improved by optimizing modeling strategies using localized indicators.

OBJECTIVES: Urinary tract infection (UTI) is the most common infection complication after kidney transplantation, and the reports of the incidence vary greatly among different centers. This study aims to explore the risk factors for UTI after kidney transplantation with the donation from brain death (DBD) and the impact on graft function, thus to provide theoretical basis for comprehensive prevention and treatment of UTI after kidney transplantation. METHODS: The clinical and laboratory data of DBD kidney transplantation from January 2017 to December 2018 in Xiangya Hospital, Central South University were collected and retrospectively analyzed. Patients were assigned into an UTI group and a non-UTI group. The base line characteristics, post-transplant complications, and graft function were compared between the 2 groups. Multivariate logistic regression was used to analyze the risk factors for UTI. RESULTS: A total of 212 DBD kidney transplant recipients were enrolled in this study. UTI occurred in 44 (20.75%) patients after transplantation. The female, the time of indwelling catheter, and postoperative urinary fistula were independent risk factors for UTI after DBD kidney transplantation. A total of 19 strains of gram-positive bacteria, 12 strains of gram-negative bacteria , and 10 strains of fungi were isolated from the urine of 44 UTI patients. The UTI after kidney transplantation significantly increased time of hospital stay ( CONCLUSIONS UTI after DBD kidney transplantation transplantation affects the renal function at 3 months and increases the patient's economic burden.

Objective:To explore the application value of whole-process ultrasound-guided percutaneous portal vein puncture islet transplantation.Methods:From October 2018 to May 2021, 16 diabetics underwent whole-process ultrasound-guided percutaneous portal vein puncture islet transplantation at First Affiliated Hospital of Sun Yat-sen University.The whole process was guided by ultrasound for completing percutaneous portal vein puncture catheterization, islet infusion monitoring, bleeding prevention and ablation hemostasis after bleeding.Results:Ten patients [8 males and 2 females with a mean age of(45.9±21.1)years]underwent 16 islet transplants, including one islet(5 cases), two islets(4 cases)and three islets(1 case). A single puncture was successfully performed without damage to other extrahepatic organs, persistent portal hypertension, portal vein embolism or infection.Bleeding at liver puncture site occurred in 3 cases and ultrasound radiofrequency ablation was performed for immediate hemostasis.Among them, postoperative blood glucose stabilized at 4~12 mmol/l post-operation.And 5 cases(31.3%)achieved insulin independence for>2 months and 10 cases(62.5%)lowered insulin dosage by>50% as compared with preoperative level.The level of fasting C-peptide recovered or was higher than normal in 10 cases(62.5%)and became obviously elevated in the remainders.In 11 cases(68.8%)of them, liver transaminase was briefly and mildly elevated post-operation, and no other complications were observed.Conclusions:The whole-process ultrasound-guided percutaneous portal vein islet transplantation is both safe and feseasible.It avoids the injury of transplanted kidney caused by contrast agent and radiological radiation to operator and patient.It is a method of islet transplantation worth a wider popularization.

Mitochondrial dysfunctions play major roles in ageing. How mitochondrial stresses invoke downstream responses and how specificity of the signaling is achieved, however, remains unclear. We have previously discovered that the RNA component of Telomerase TERC is imported into mitochondria, processed to a shorter form TERC-53, and then exported back to the cytosol. Cytosolic TERC-53 levels respond to mitochondrial functions, but have no direct effect on these functions, suggesting that cytosolic TERC-53 functions downstream of mitochondria as a signal of mitochondrial functions. Here, we show that cytosolic TERC-53 plays a regulatory role on cellular senescence and is involved in cognition decline in 10 months old mice, independent of its telomerase function. Manipulation of cytosolic TERC-53 levels affects cellular senescence and cognition decline in 10 months old mouse hippocampi without affecting telomerase activity, and most importantly, affects cellular senescence in terc cells. These findings uncover a senescence-related regulatory pathway with a non-coding RNA as the signal in mammals.

Mammalian mitochondrial genome encodes a small set of tRNAs, rRNAs, and mRNAs. The RNA synthesis process has been well characterized. How the RNAs are degraded, however, is poorly understood. It was long assumed that the degradation happens in the matrix where transcription and translation machineries reside. Here we show that contrary to the assumption, mammalian mitochondrial RNA degradation occurs in the mitochondrial intermembrane space (IMS) and the IMS-localized RNASET2 is the enzyme that degrades the RNAs. This provides a new paradigm for understanding mitochondrial RNA metabolism and transport.

Objective To investigate the effects of multimodal analgesia of parecoxib and fentanyl on perioperative immune functions in patients of hepatocellular carcinoma (HCC).Methods Eighty HCC patients scheduled for hepatectomy were randomly divided into two groups:parecoxib sodium combined with fentanyl group (group P,40 cases) and fentanyl group (group C,40 cases).The percentages of CD3 +,CD4+,CD8+,CD4+/CD8+ T cells,CD3-CD16+ CD56+ (NK),interleukin-4 (IL-4),interferon-γ (IFN-γ) and the ratio of IFN-γ/IL-4 were detected at the following time points:30 minutes before induction of anesthesia (T0),at the end of the surgery (T1),24 h after surgery (T2) and 72 h after surgery (T3).The analgesic effects were estimated by visual analogue scale (VAS) after surgery.Total fentanyl consumption and adverse effects were also recorded.Results The percentages of CD3 + T cells were significantly lower in group C than that in group P at T2 (t =2.155,P ＜0.05).The percentages of NK in group P were recovered nearly to baseline (T0) at T2,which was higher than that of group C (t =2.791,P ＜0.05).In group C,the percentages of CD3 + T cells and NK has not recovered to baseline at T3 (respectively t =3.065,3.231,P ＜ 0.05).In group P,IL-4 serum levels were significantly lower than those in group C,while IFN-γ serum levels were significantly higher than those in group C at T2 (respectively t =2.173,2.100,P ＜0.05).From T2 to T3,the ratio of IFN-γ/IL-4 significantly increased in group P than those in group C (respectively t =3.259,2.203,P ＜ 0.05).VAS scores at rest and on cough in group P were significantly lower than those in group C at 2 h,6 h,12 h and 24 h after operation (respectively t =8.661,9.726,9.147,7.109,P＜0.05;t =8.569,9.614,9.144,8.509,P＜0.05).The total fentanyl consumption in group P was lower than that in group C (t =2.636,P ＜ 0.05).There were no significant differences regarding the incidence of adverse effects between the two groups.Conclusions Perioperative multimodal analgesia of parecoxib sodium combined with fentanyl enhances the analgesic efficacy,and reduces the dosage of opioid consumption,helps recover the cell immunity function of HCC patients after hepatectomy.

OBJECTIVE: To determine the effect of transient withdrawal of immunosuppressive agents during the treatment of pulmonary infection on long-term survival of patients and graft s. METHODS: A total of 104 patients with post-transplant pulmonary infection were enrolled in this study. These patients received renal transplantation in Center for Organ Transplantation, Xiangya Hospital, Central South University, during December 2005 and August 2014. Among them, 50 patients stopped immunosuppressive agents during the treatment of infection. These patients served as stopping drug (SD) group, whereas the remaining patients who served as a control group did not stop immunosuppressive drugs. The five-year cumulative patient survival, graft survival, and laboratory results were compared between the 2 groups. RESULTS: The five-year cumulative patient survival rates in the SD group were significantly lower than those in the control group [(69.8 ± 7.0)% vs (94.2 ± 3.2)%, P=0.001]. There was no significant difference in the allograft survival rates between the 2 groups [(81.7 ± 6.6)% vs (90.9 ± 4.3)%, P=0.113]. In patients who survived from pulmonary infection, there was no significant difference in long-term survival rates between the 2 groups (P=0.979). CONCLUSION Pulmonary infection impacts allograft survival after patients underwent renal transplantation. Transient stopping immunosuppressive agents during the treatment of infection is a safe and necessary treatment strategy for patients with serious post-transplant pulmonary infection.
