[Objective] To investigate the protective effect of Salvia miltiorrhiza injection (SMI) on the kidneys of HBOC-CHP01 resuscitated haemorrhagic shock rats. [Methods] A 50% haemorrhagic shock rat model was established, with 12 rats divided into two groups: SMI + HBOC-CHP01 group and HBOC-CHP01 group, with 6 rats in each group. The rats in the SMI+ HBOC-CHP01 group were given an equal volume of HBOC-CHP01 for resuscitation after haemorrhagic shock, and an 8 mL/kg dose of SMI. Rats in the HBOC-CHP01 group were resuscitated by administering an equilibrium blood loss volume of HBOC-CHP01 and given an 8 mL/kg dose of 0.9% NaCl solution. Blood was taken from rats at five points: before bloodletting (baseline), during haemorrhagic shock (HS), immediately after resuscitation (RS0h), 1 h after resuscitation (RS1h), and 24 h after resuscitation (RS24h). A blood gas analyser was used to detect the lactate level (Lac), glucose content (Glu), residual base (BEecf), pH, bicarbonate (HCO3-), high iron haemoglobin (MetHb). White blood cells (WBC), platelets (PLT), haemoglobin content (Hb), carboxyhaemoglobin (COHb) were detected using a quintuple classification. Blood creatinine (SCr), uric acid (UA), kidney-related indexes were detected using biochemistry instrument. Kidney tissues of the rats were taken after 24 h of resuscitation and after execution, and the inflammation of kidneys of the rats of the two groups was analyzed using HE staining. Fluorescence staining was used to detect the level of ROS in the kidneys of rats in both groups. [Results] At RS 0h, the Beecf, Glu and Lac levels of rats in the SMI+HBOC-CHP01 group were significantly lower than those of rats in the HBOC-CHP01 group, and the pH level of rats in the SMI+HBOC-CHP01 group was significantly higher than that of rats in the HBOC-CHP01 group, and the Glu levels of rats in the SMI+HBOC-CHP01 group were significantly lower than those of rats in the HBOC-CHP01 group at RS 1h. At RS 0h, the WBC, PLT and COHb contents of rats in the SMI+HBOC-CHP01 group were all significantly higher than those of rats in the HBOC-CHP01 group, and at RS 1h, the WBC content of rats in the SMI+HBOC-CHP01 group was significantly higher than that of rats in the HBOC-CHP01 group; at RS 1h, the UA content of rats in the SMI+HBOC-CHP01 group was significantly lower than that of rats in the HBOC-CHP01 group; at RS 24h, the SCr content of rats in the SMI+HBOC-CHP01 group was significantly lower than that of rats in the HBOC-CHP01 group; at RS 24h, the inflammation level of kidney tissues of rats in the SMI+HBOC-CHP01 group was significantly lower than that of rats in the HBOC -CHP01 group rats, and the ROS and MPO levels in the kidney tissues of rats in the SMI+HBOC-CHP01 group were significantly lower than those of rats in the HBOC-CHP01 group. [Conclusion] The combination of Salvia miltiorrhiza injection during the resuscitation of rats with severe haemorrhagic shock by HBOC-CHP01 can alleviate renal injury by reducing inflammatory response and oxidative stress.

Objective:To explore the long-term therapeutic efficacy and outcomes of liver transplantation for patients with hepatic myelopathy (HM).Methods:Retrospective analysis of 24 adult liver transplantation recipients due to HM at First Central Municipal Hospital from January 2006 to October 2022. HM was extensively classified by the severity of lower extremity symptoms, degree of muscle stiffness, capability for independent ambulation and muscle strength. Furthermore, their long-term outcomes were examined. From January 2000 to October 2022, the databases of China National Knowledge Infrastructure (CNKI) , Google Scholar, PubMed and Web of Science were searched with such keywords as "肝性脊髓病and肝移植" "Hepatic Myelopathy and Liver Transplantation" .Results:After liver transplantation, liver functions and blood ammonia normalized and most clinical symptoms improved. During a follow-up period of (12-190) months, 19 patients showed a lowered grade of HC as compared to pre-transplantation. Four cases achieved a complete recovery of extremity function. No change occurred in severity grade for the remaining 5 patients. However, 4 of them experienced varying degrees of improvement in muscle strength and independent walking capability. This review summarized the clinical characteristics and clinical outcomes of 17 patients from both domestic and international sources. Most of them experiences varying degrees of symptomatic improvements after liver transplantation (16 cases).Conclusions:This study has confirmed the effectiveness of liver transplantation for HM and its contribution to the long-term patient recovery.

As an effective treatment for end-stage liver disease, liver transplantation has been widely carried out worldwide and gradually captivated widespread recognition. With the advancement of liver transplantation techniques, the incidence of postoperative complications has been gradually declined, and the short-term and long-term prognosis of recipients have been constantly improved. However, a huge gap has existed between the supply and demand of donor organs, which is a major factors restricting the development of liver transplantation. The amount of liver transplantation operation in China is increasing year by year, the shortage of donor liver is becoming more and more prominent, and marginal donor liver is increasingly used in clinic. In recent years, the selection criteria of donor organs, organ preservation and functional maintenance have been continuously improved. In this article, the application and development trend of different techniques were reviewed from the perspectives of donor liver preservation and functional maintenance, and recent technical development and research results were summarized, aiming to provide reference for further enhancing the survival rate of grafts and recipients and promoting the development of liver transplantation in China.

ObjectiveTo investigate the effect of microRNA-223-3p （miR-223-3p） on hepatic stellate cell （HSC） activation and its mechanism. MethodsHuman HSC LX2 cells were selected for the study， and LX2 cells were stimulated by TGF-β to establish a model of HSC activation； quantitative real-time PCR was used to measure the change in the expression level of miR-223-3p during HSC activation. After LX2 cells were transfected with miR-223-3p mimic， quantitative real-time PCR， Western blot， and immunofluorescence assay were used to clarify the regulatory effect of miR-223-3p on HSC activation， and dual-luciferase reporter assay was used to verify the association between miR-223-3p and the target gene MAP1B. After LX2 cells were transfected with MAP1B siRNA， Western blot was used to clarify the influence of inhibiting MAP1B expression on HSC activation； after LX2 cells were transfected with miR-223-3p， quantitative real-time PCR and Western blot were used to verify the regulatory effect of miR-223-3p on MAP1B. The independent-samples t test was used for comparison of continuous data between two groups. ResultsHSC in the activated state had a significant reduction in the expression level of miR-223-3p compared with those in the resting state （t=9.12， P<0.001）. Overexpression of miR-223-3p inhibited the mRNA and protein expression levels of the markers for HSC activation alpha-smooth muscle actin and collagen type Ⅰ （mRNA expression： t=8.35 and 12.23， both P<0.01； protein expression： t=16.24 and 20.90， both P<0.001）. The dual-luciferase reporter assay confirmed that MAP1B was a potential target gene of miR-223-3p. Compared with the control group， LX2 cells with miR-223-3p overexpression had significant reductions in the mRNA and protein expression levels of MAP1B （mRNA expression： t=5.95， P<0.01； protein expression： t=11.12， P<0.001）. ConclusionThis study shows that miR-223-3p can inhibit HSC activation by targeting MAP1B.
