BACKGROUND:Delayed graft function (DGF) occurs frequently in kidney transplants from donation after cardiac death if creatinine level is high in kidney recipients. OBJECTIVE:To analyze the clinical effects of renal transplantation with kidneys from donors dying of cardiac death in organophosphate poisoning. METHODS:Data were col ected from kidney transplants from two donors dying of cardiac death in organophosphate poisoning. After some donor maintenance, donor organ were obtained and perfused with impulse type machine. Recipients were treated with intervention of immunity induction, anti-rejection drugs and infection prevention drugs during and after renal transplantation. Pathological data of donor kidney zero needle biopsy, DGF after kidney transplantation, complication rate (such as acute rejection), renal al ograft recovery situation, the survival rate of recipients and kidney transplants were col ected and analyzed. RESULTS AND CONCLUSION:Needle biopsy results from four donor kidneys showed that glomerular morphology was normal, but there were edema and degeneration in kidney tubules in some degree. Donor DGF rate was 75%(3/4), acute rejection rate was 0%(0/4), perioperative period donor kidney and recipient survival rate were 100%(4/4). Al recipients showed a good result of transplanted kidney, their creatinine and urea nitrogen were at low level, and had no proteinuria. One recipient died of severe pulmonary infection 4 months after surgery. For some organophosphate poisoning donors dying of cardiac death, donor kidney quality can be improved by suitable donor maintenance and high-quality donor kidney preservation using machine perfusion. Kidney transplants from donors dying of cardiac death in organophosphate poisoning who receive the maintenance of organ function may be a promising candidate for renal transplantation due to a severe lack of kidney donor sources.

Objective To compare the therapeutic effects of orthotopic injection and tail vein injection of human amniotic mesenchymal stem cells(hAMSCs)on histological restoration and neurological functions of rats with spinal cord injury. Methods Transected spinal cord injury model in rats was established by transplanting DAPI prelabelled hAMSCs one week after injury.BBB scores were used to evaluate the hindlimb movement of rats. The histological patterns.and morphology of medullary sheath of spinal cord were observed. Results BBB scores in the orthotopic injection group and tail vein injection group were increased gradually from one to six week after hAM-SCs transplantation and reached 6.5 ± 0.5 and 7.12 ± 1.61 respectively 6 weeks after cell transplantation,higher than that of the control group(both P < 0.01). However,there was no statistical significance between the two groups.Histological results indicated that the repair of injured tissue in the orthotopic injection group and tail vein injection group were both better than that in the control group,and there were more vesica and loosened layers forming in the injured spinal cord of rats in the PBS control group as compared with the orthotopic and tail vein transplantation group. Conclusion hAMSCs transplantation through tail vein injection could promote histological restoration and neurological regeneration of rats with spinal cord injury,which has the similar therapeutic effects with hAMSCs orthotopic transplantation.

Under the background of severe shortage of donor organs and organ donation after citizen's death becoming the main source of donor organs in China, expanded criteria donor (ECD) has been widely applied in clinical practice. However, ECD has the disadvantages of basic diseases, old age, trauma, shock or infection, which will affect the quality of donor organs to varying degrees and become one of critical factors affecting clinical efficacy of organ transplantation. The recipients of ECD organ transplantation will also bear the additional risk and uncertainty of efficacy brought by ECD organs. Hence, it is necessary to pay attention to the protection of the recipients’ rights and interests. In this article, ethical issues faced by ECD organ transplantation in recipient protection and the shortcomings in the ethical review of organ ethics committee were reviewed, and suggestions on the ethical review institution and system construction of the rights and interests of organ transplantation recipients were elucidated, aiming to provide reference for promoting the advancement of ECD organ transplantation.

Organ shortage is one of the important factors restricting the development of human organ transplantation. The identification and referral of potential donors determine the total scale of organ donation. Whether potential donors can be identified and referred is the most important reason for the difference of organ donation rates in different regions. This paper interprets the chapter of the identification and referral of potential donors in the Guide to the Quality and Safety of Organs for Transplantation (6th edition) issued by European Union in order to provide reference for the staff of organ procurement organization and related medical personnel in China and improve the organ donation rate in China.

Objective By analyzing the perioperative management in our hospital to explore the clinical effect and safety of single kidney transplantation from deceased juveniles' donors.Methods We retrospectively analyze 86 cases of kidney transplantations from deceased juveniles' donors in our hospital from 2007 December to 2015 August.Results The success rate of the operations was 100％.The postoperative complications occurred as fellows:7 cases of acute rejection (8.14％);10 cases of drug intoxication (11.62％);21 cases of DGF (24.44％),4 cases of leakage of urine (4.65％),7 cases of lung infection (8.14％).Two cases (2.32％) died after the operation because of serious lung infection,and by corresponding treatment 47 cases recovered after 2-4 weeks.The creatinine level in 37 cases without any complications was 131.88 ± 44.20 μmol/L during discharge.Conclusion With strict selection,the organ from a deceased juvenile donor is safe and practicable.

Objective:To examine the technique and effect of combined thoracic and abdominal organ clusters resection.Methods:From February 2019 to August 2021, totally 50 cases of combined thoracoabdominal organ cluster resection were completed at Transplant Medical Center, the Second Affiliated Hospital of Guangxi Medical University from donation after brain death donors. There were 47 males and 3 females, aging (34.8±12.3) years (range: 5 to 55 years). The length of hospital stay( M(IQR)) was 4(4) days (range: 2 to 43 days), the length of tube time was 4(2) days (range: 1 to 43 days). Through the midsternal incision and the abdominal grand cross incision, the cold perfusion was performing simultaneously when the perfusion lines of each target organ was established respectively. The combined resection was performed with the diaphragm as the boundary and the organ cluster as the unit. The heart and lung were separated on site and sent to the transplant hospital, and the abdominal organ cluster was directly preserved and returned to our hospital for further separation and repair. Results:Totaly 21 hearts, 47 pairs of lungs, 49 livers, 47 pairs of kidneys and 11 pancreas were harvested by this surgical treatment. The resection time was (32.6±6.5) minutes (range: 19 to 50 minutes), with no hot ischemia time. There was no accidental injury that affected organ quality and function. Heart transplantation was performed in 17 cases, combined heart-kidney transplantation in 2 cases, double lung transplantation in 43 cases, single lung transplantation in 6 cases, liver transplantation in 41 cases, combined liver-pancreas-duodenal cluster transplantation in 1 case, combined liver-kidney transplantation in 3 cases, combined pancreas-kidney transplantation in 9 cases, and kidney transplantation in 74 cases.Conclusion:Simultaneous perfusion and combined resection of thoracic and abdominal organ clusters for donation after brain death donors are feasible and effective.

The global distribution of medical resources is uneven and organ shortages are becoming increasingly serious. ASEAN countries have been working hard to explore and promote local organ transplantation in order to alleviate the serious imbalance between organ donation and organ transplantation needs. However, the development of cadaveric organ donation varies among ASEAN countries, and the cadaveric organ donation rate in most countries is generally low. Since 1991, China and ASEAN have evolved from dialogue to strategic cooperation, then to a community with a shared future, and further to a comprehensive strategic partnership, all demonstrating broad prospects for cooperation. This article analyzes the current situation and challenges of organ donation and transplantation in ASEAN countries, combining field visits and its own experience, and proposes strategies for strengthening international cooperation, optimizing policy environment, enhancing technical capabilities, and increasing public awareness in the field of organ donation and transplantation under the China-ASEAN development strategy framework. The aim is to build a more equitable, efficient, and sustainable organ donation and transplantation system, contributing to the realization of global public health security and a community of common health for mankind.

"Chinese model" of organ donation and transplantation in China has won acclaims from all over the world. Current contradictions between unbalanced and inadequate development of organ donation and transplantation and surging public demands for transplant services remain serious. And an acute shortage of donated organs is still the greatest difficulty. Improving organ donation rate per million population (PMP) and organ utilization rate has been a great challenge for organ donation teams in China. This review summarized the relevant experiences of Second Affiliated Hospital of Guangxi Medical University in fostering organ donation culture atmosphere and connotation to accelerate the high-quality development of organ donation. It was intended to provide references for disciplined construction of other organ donation management teams and promote the development of organ donation and transplantation in China.
