Comparative analysis of performance evaluation indexes of public medical institutions in China / 中华医院管理杂志

The reform of public medical institutions is a critical and difficult breakthrough in furthering the healthcare system reform in China, for which the performance appraisal of public hospitals can serve an important role. The performance policy documents of tertiary public hospitals, secondary public hospitals and primary medical and health institutions in China since 2019 were compared and analyzed, to systematically identify the similarities and differences and development rules of the three evaluation index systems. The study analyzed the impacts of the three systems on the management of medical institutions and provided reference suggestions for improving their performance evaluation. It was found that all the three systems aim at guiding tertiary public hospitals to evolve from the pattern centering on scale expansion to that on quality and benefits, guiding secondary ones to improve their capacity of medical services, and guiding primary medical institutions to focus on basic medical and public health services. However, these systems lack indexes on hierarchical diagnosis and treatment for secondary hospitals and application of examination results, while national surveillance indexes on primary ones accounted for only 23.8% of all. It is recommended to dynamically adjust both the performance evaluation index system and the surveillance methods, and to enhance the application of examination results and development of supporting policies as well.

Operative strategy and short-term efficacy of recurrent groin hernia / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To explore the appropriate operative strategy in recurrent groin hernia repair.</p><p><b>METHODS</b>Clinical and follow-up data of 82 patients with recurrent groin hernia undergoing operation at Department of Pancreatobiliary Surgery, Xiangya Hospital of Central South University from April 2010 to April 2017 were analyzed retrospectively. The operative approaches included laparoscopic transabdominal preperitoneal (TAPP) hernia repair, Lichtenstein repair and hybrid repair. Surgical method selection was based on the basis of European Hernia Society guidelines, combined with hernia histories, preoperative examination results and intra-operative results: (1) When an anterior approach (Lichtenstein, Bassini or Shouldice surgery) was adopted in the previous operation, TAPP was preferred for the recurrent groin hernia. (2) When the previous operation was an posterior approach [TAPP or total extraperitoneal hernioplasty (TEP)], Lichtenstein method was preferred. Moreover, Lichtenstein surgery with local anesthesia or nerve block was also selected when the patient could not tolerate general anesthesia. (3) When extensive preperitoneal adhesions were found in patients with previous anterior approach repair during laparoscopic exploration, especially in patients who had relapsed after multiple operations or had previous biochemical glues injection, hybrid surgery was preferred.</p><p><b>RESULTS</b>All 82 patients completed operations smoothly. TAPP, Lichtenstein and hybrid operation were applied in 74, 4 and 4 patients, respectively, with median operative time of 70 minutes (40-130 minutes) in TAPP, 60 minutes (40-90 minutes) in Lichtenstein and 120 minutes (70-150 minutes) in hybrid operation, respectively. The median numerical rating scales (NRS) score was 2 (0-6) on postoperative day 1. The incidences of postoperative seroma, pain and urinary retention were 4.9% (4/82), 2.4% (2/82) and 1.2% (1/82) respectively. The median postoperative hospital stay was 2 days (1-6 days). Seventy-two patients were followed-up from 11 to 87 months. The median follow-up period was 27 months. The median inguinal pain questionnaire (IPQ) score was 2 (0-8) month after operation. One recurrent case was reported 1 year after operation. No incision or mesh infection and long-term inguinal chronic pain were observed.</p><p><b>CONCLUSIONS</b>For recurrent patients with previous open anterior approach, TEP and TAPP repair are equivalent surgical techniques, and the choice should be tailored to the surgeon's expertise. For those with previous TAPP or TEP repair, Lichtenstein technique is recommended. For those with adhesions both in anterior transverse fascia and pre-peritoneum, hybrid operation may be the preferable choice according to adhesion conditions.</p>

The trends in surgical treatment and the outcomes of critical acute pancreatitis / 中华肝胆外科杂志

Objective To study the trends in surgical treatment and the outcomes of critical acute pancreatitis (CAP).Methods The clinical data of 76 patients with CAP who were treated in the Department of Biliopancreatic Surgery of the Xiangya Hospital,Central South University from January 2010 to December 2017 were retrospectively reviewed.Data which included demographics,micro-organisms,surgical interventions and mortality were compared between the time periods of 2010 to 2013 and 2014 to 2017.Results Before 2014,19 patients with CAP were treated in the Department of Biliopancreatic Surgery of the Xiangya Hospital,Central South University.The percentage of multidrug resistant organisms (MDRO) in pancreatic drainage was 5.3％ (1/19).In the latter 4 years,57 patients with CAP were treated.The percentage of MDRO was 50.9％ (29/57),which was significandy higher than the initial 4 years (P＜0.001).For surgical treatment,the proportion of minimally invasive surgery in the latter 4 years was significantly higher than that in the initial 4 years.The percentage of percutaneous catheter drainage (PCD) increased from 63.2％ in the initial 4 years to 86.0％ in the latter 4 years.The proportion of minimal access retroperitoneal pancreatic necrosectomy (MARPN) increased from zero in the initial 4 years to 59.6％,while the proportion of open pancreatic necrosectomy (OPN) decreased from 68.4％ in the initial 4 years to 24.6％.The mortality rate of patients with CAP dropped from 52.6％ (10/19) in the initial 4 years to 24.6％ (14/57) in the latter four years.Conclusions In the center which specializes in treating pancreatitis,although the problem of bacterial resistance had become increasingly prominent,the mortality rate of CAP had shown a significant downward trend due to the development of various minimally invasive techniques.

Objective To investigate prognosis and related factors of infectious pancreatic necrosis(IPN) caused by multidrug-resistant organisms(MDROs).Methods Clinical data of 53 IPN patients admitted to a hospital between October 2010 and March 2016 were analyzed retrospectively,patients were divided into MDRO infection group and common bacterial infection group according to antimicrobial resistance of pathogens isolated from peripancreatic drainge fluid,prognosis and related factors of two groups were compared.Results Among 53 IPN patients with confirmed evidence for pathogenicity,33(62.3％)were in MDRO infection group,and 20(37.7％)were in common bacterial infection group,the most common MDROs isolated from peripancreatic drainage was multidrug-resistant Acinetobacter baumannii (MDRO-AB) (37.5％,18/48).The mortality of IPN patients was 30.2％ (16/53),mortality of MDRO infection group was higher than common bacterial infection group(39.4％ [13/33] vs 15.0％ [3/ 20],P＜0.05);the severity score,length of intensive care unit (ICU) stay,and hospitalization expenses in MDRO infection group were all higher than common bacterial infection group(all P＜0.05).The mortality of IPN patients were closely associated with MDRO infection and severity score of acute pancreatitis (all P ＜ 0.05).Conclusion Prognosis of patients with MDRO infection is poor,treatment is difficult,MDRO infection has become one of the most important challenge to the treatment of severe acute pancreatitis.

Protective role of triptolide in a rat model of antibody-mediated rejection in kidney transplantation / 中华器官移植杂志

Objective To investigate the protective effect and the mechanisms of triptolide on antibody-mediated rejection (AMR) in kidney transplantation.Method A rat model of AMR in kidney transplantation was constructed by sensitizing major histocompability complex (MHC) completely incompatible species of rats via blood transfusion before kidney transplantation.The protective effect of Triptolide on the renal function and pathologic injury was studied in this rat model.The levels of donor specific antibodies were measured by flow cytometry.C4d expression and macrophage infiltration were examined by immunohistochemistry and immunofluorescence.Result Triptolide could improve the function of transplanted kidney significantly (P＜0.05) and alleviate the pathologic injury.Triptolide can also reduce the levels of IgM,IgG2b and IgG2c in the serum of the recipient rats and inhibit the macrophage infiltration as well (P＜0.05).Conclusion Triptolide plays protective and therapeutic roles in AMR of kidney transplantation,which may be contributed to the inhibition of the production of donor specific antibody and the macrophage infiltration.

Fibronectin splice variant connecting segment-1 peptides protect sinusoidal endothelial cells and alleviate ischemia/reperfusion injury in rats / 中华器官移植杂志

Objective To examine the effect of fibronectin connecting segment-1 (CS1) peptidefacilitated blockade of inflammatory cells-fibronectin adhesion on a rat liver transplantation model of prolonged ex vivo cold ischemia.Methods A model of liver transplantation in Wistar→Wistar rat was established.The donors of the CS1 treatment group received CS1 peptides through the tail vein for 3 days before operation.Another two doses of CS1 peptides were administered into the liver intraportally during procurement and before transplantion.Recipients received an additional 3-day course of CS1 peptides after transplantation.Rats in control group received scrambled peptides.Rats were sacrificed at 6,24 and 72 h after transplantion,and plasma transaminase activity and hepatic pathological changes were studied.The inflammatory cells and liver sinusoidal endothelial cells were visualized histochemically.Real-time PCR was used to detect tumor necrosis factor-α (TNF-α),interleukin-1β (IL-1β) and vascular endothelial growth factor (VEGF) mRNA expression in the liver.Results The plasma transaminase activity and hepatic necrosis areas in CS1 treatment group were significantly lower than in control group (P＜0.05).CS1 peptides treatment significantly decreased the number of Kupffer cells after transplantation and greatly inhibited the recruitment of neutrophils to the graft liver as compared with control group (P＜0.05).After prolonged cold ischemia,only a few hepatic endothelial cells exhibited positive staining of hepatic sinusoidal endothelial cell biomarker SE-1.Lots of hepatic sinusoidal endothelial cells positive for SE-1 staining could be detected in CS1 group at 72 h after transplantation,while much less SE-1 positive cells presented in the control goup.Prolonged cold ischemia caused a significant increase of TNF-α,IL-1β and VEGF mRNA expression in the graft liver of control group after transplantation.The expression of TNF-α mRNA at 6 and 24 h and VEGF mRNA expression at 24 h were significantly lower in CS1 group than in control group (P＜0.05).Conclusion Peptide-mediated blockade of inflammatory cells-fibronectin interaction decreased the mRNA expression of inflammatory cytokines,prevented hepatic sinusoidal endothelial cells from injury and subsequently protected against severe ischemia/reperfusion injury of the graft liver after transplantation.
