ABSTRACT

Objective To provide guidance for pre-hospital emergency treatment by studying the disease spectrum and distribution characteristics of pre-hospital emergency treatment patients in Wuxi area from 2015 to 2020. Methods The medical records of 120 pre-hospital emergency patients in Wuxi area from January 2015 to December 2020 were retrospectively analyzed, and the disease types, gender, age, and seasonal distribution of the pre-hospital emergency patients were statistically analyzed. Results The top five emergency diseases of 16 437 pre-hospital patients were trauma (24.51%), cerebrovascular disease (19.16%), cardiovascular disease (18.33%), digestive system disease (9.70%) and respiratory disease (7.20%). In the distribution of disease types, the proportions of injuries, cerebrovascular diseases, cardiovascular diseases, digestive system diseases, respiratory system diseases, poisoning diseases and urinary system diseases in males were significantly higher than those in females (χ2=4.975, P<0.05). The proportion of male species (9 812/16 437) was higher than that of female species (6 625/16 437). From 2015 to 2020, the age group with high incidence of pre-hospital emergency patients in Wuxi area was distributed in the 50-60 years old (19.30%) and 40-50 years old (16.28%), and the least age group was 0-10 years old (2.60%). The number of pre-hospital emergency patients was 46.60% from 6 to 12 hours per day, and 10.26% from 18 to 24 hours per day. The number of pre-hospital emergency patients was the highest in summer (38.69%), and the lowest in spring (11.87%). Conclusion The pre-hospital emergency diseases in Wuxi area are mainly cardiovascular and cerebrovascular diseases, and the acute and severe diseases show an increasing trend. It is necessary to rationally allocate the pre-hospital emergency resources according to the disease spectrum and the peak months and time periods of different diseases, so as to improve the medical service level in Wuxi.

ABSTRACT

Objective To analyze the prediction efficiency of scoring models at home and abroad on delayed graft function (DGF) after renal transplantation in China. Methods The clinical data of 112 donors and 220 recipients undergoing renal transplantation were prospectively analyzed. The DGF predicted by KDRI model, Jeldres model, and model of our center was compared with actual DGF incidence of renal transplant recipients. The prediction efficiency of each model was analyzed. The predictive accuracy was compared by the area under curve (AUC) of receiver operating characteristic (ROC) curve. Results The DGF incidence of 220 renal transplant recipients was 14.1% (31/220). DGF prediction using KDRI model showed that 41 cases were high risk donors, the AUC was 0.57, the sensitivity was 0.37, the specificity was 0.66, and the positive predictive value was 22%. DGF prediction using Jedres model showed that 22 cases were high risk recipients, the AUC was 0.56, the sensitivity was 0.13, the specificity was 0.92 and the positive predictive value was 20%. DGF prediction using the model of our center showed that 25 cases were high risk donors, the AUC was 0.80, the sensitivity was 0.53, the specificity was 0.84, the positive predictive value was 40%. Conclusions Compared with the KDRI and Jedres models, the prediction model of our center has higher AUC and sensitivity with a better prediction efficiency on DGF. Therefore, it is a suitable evaluation system of donors from donation after citizen's death in Chinese.

ABSTRACT

Objective:To summarize the patient profiles and therapeutic efficacies of ABO-incompatible living-related kidney transplantations at 19 domestic transplant centers and provide rationales for clinical application of ABOi-KT.Methods:Clinical cases of ABO-incompatible/compatible kidney transplantation (ABOi-KT/ABOc-KT) from December 2006 to December 2009 were collected. Then, statistical analyses were conducted from the aspects of tissue matching, perioperative managements, complications and survival rates of renal allograft or recipients.Results:Clinical data of 342 ABOi-KT and 779 ABOc-KT indicated that (1) no inter-group differences existed in age, body mass index (BMI), donor-recipient relationship or waiting time of pre-operative dialysis; (2) ABO blood type: blood type O recipients had the longest waiting list and transplantations from blood type A to blood type O accounted for the largest proportion; (3) HLA matching: no statistical significance existed in mismatch rate or positive rate of PRA I/II between two types of surgery; (4) CD20 should be properly used on the basis of different phrases; (5) hemorrhage was a common complication during an early postoperative period and microthrombosis appeared later; (6) no difference existed in postoperative incidence of complications or survival rate of renal allograft and recipients at 1/3/5/10 years between ABOi-KT and ABOc-KT. The acute rejection rate and serum creatinine levels of ABOi-KT recipients were comparable to those of ABOc-KT recipients within 1 year.Conclusions:ABOi-KT is both safe and effective so that it may be applied at all transplant centers as needed.

ABSTRACT

<p><b>BACKGROUND</b>People's attitude toward organ donation after cardiac death (DCD) has not come to an agreement in different countries and regions. Influenced by the local culture in China for thousands of years, the general public has different ideas about this issue. The purpose of this study was to investigate the current attitudes trend and characteristics of transplantation with organs donated after cardiac death in northwest China.</p><p><b>METHODS</b>This largest single-center cohort study was performed by an interview or by telephone using a questionnaire. The family members of potential DCD donors were recruited from the First Affiliated Hospital, medical college of Xi'an Jiaotong University located in a metropolitan area of northwest China. The 12-item attitude questionnaire was specifically developed from the literature review with coordinator, physician, and donor's family feedback. The participants were asked to rate the queries on a 5-point Likert intensity scale.</p><p><b>RESULTS</b>The 174 participants included 56 (32.2%) women and 118 (67.8%) men. Most people were aged between 41 and 50 years (n = 63, 36.2%), 31 and 40 years (n = 59, 33.9%), and less than 30 years (n = 36, 20.7%). The top five attitudes of participants were the best person to suggest organ donation to a family was ranked as the DCD coordinator of Red Cross Organization (RCO, n = 160, 92%), donor is a hero (n = 143, 82.2%), honor to be a donor's family member (n = 136, 78.2%), improved relationship with colleagues (n = 124, 71.3%), and with recipient after donation (n = 123, 70.7%). The best person to suggest organ donation to a family was ranked as the coordinator of RCO (n = 160, 92%), doctor unrelated to transplantation (n = 104, 59.8%), social worker (n = 36, 20.7%), and doctor related to transplantation (n = 25, 14.4%). The top two reasons for non-consent to donation were that the family insisted on intact body after patient death and did not want to have surgery again (n = 51, 41.5%), and feared that they would be misunderstood by neighbors, relatives, and friends about donation (n = 28, 22.8%).</p><p><b>CONCLUSIONS</b>This study revealed initial attitudes toward DCD in China. Some data afford insight into the decision-making procedure. The concerns of potential DCD donors and their families may help professionals provide better interventions in the future.</p>

ABSTRACT

OBJECTIVE@#To investigate islet graft survival and function after co-culture and co-transplantation with vascular endothelial cells (ECs) in diabetic rats.@*METHODS@#We isolated ECs, and assessed the viability of isolated islets in a group of standard culture and a group of co-culture with ECs. Then we put the diabetic rats in 4 groups: an islet transplantation group, an islet graft with EC transplantation group, an EC transplantation group, and a PBS control group. Blood glucose and insulin concentrations were measured daily. Cell morphology and cell markers were investigated by immunohistochemical staining and electron microscope.@*RESULTS@#Normal morphology was shown in more than 90% of AO/PI staining positive islets while co-cultured with ECs for 7 days. Insulin release assays showed a significantly higher simulation index co-culture except for the first day (P<0.05). There was a significant difference in concentrations of blood glucose and insulin among the 4 groups after 3 days after the transplantation (P<0.05).@*CONCLUSION@#EC-islet co-culture can improve the function and survival of isolated islets in vitro, and EC-islet co-transplantation can effectively prolong the islet graft survival in diabetic rats.

ABSTRACT

Objective To summarize the incidence and treatment experience of the effectiveness and adverse reactions of the different immunosuppressive protocols and to increase the long-term survival rate in kidney recipients. Methods Single-center retrospective analysis was performed on 3102 cases of kidney transplant recipients in effectiveness and adverse reactions of different immunosuppressive protocols. The immunosuppressive protocols were as follows: CsA + Aza + Pred,low dose CsA + MMF + Pred, low dose Tac + MMF + Pred, low dose CsA + SRL + Pred, and low dose Tac+ SRL+ Pred. Results The 1-, 5-, 10-year survival rate of patients/kidney in low dose CsA + MMF + Pred protocol was higher than that in CsA + Aza + Pred protocol. The incidence of adverse reactions, such as hypertension, hyperuricemia, kidney and liver toxicity, and leukopenia was significantly lower, but the incidence of diarrhea was significantly higher in CsA + MMF + Pred protocol than in CsA + Aza + Pred protocol (all P<0. 01). The incidence of hyperglycemia was significantly higher (P<0. 05), and that of hairy and gingival hyperplsia was significantly lower (P<0. 05) in low dose Tac+ MMF+ Pred than in low dose CsA+ MMF+ Pred protocol. The incidence of hyperlipidemia in low dose CsA (or Tac)+ SRL + Pred was significantly higher than in CsA (or Tac)+ MMF+ Pred protocol (P<0. 05). The incidence of hirsutism in low dose Tac + SRL + Pred was significantly lower than that in CsA + SRL + Pred protocol (P < 0. 05). The incidence of hyperglycemia in low dose Tac + SRL + Pred was significantly higher than that in low dose CsA + SRL + Pred protocol. Conclusion The triple drug protocol with a low dose of CsA (or Tac)+ MMF+ Pred significantly improved the survival of renal transplant recipients and graft, and reduced the incidence of adverse reactions, especially Tae + MMF + Pred protocol. Adjustment of the immunosuppressant dosage and protocol, improvement of eating habits, exercise, reduction of blood pressure, reduction of blood lipid, and control of blood glucose were particularly important in preventing and controlling adverse reactions during kidney transplantation.

ABSTRACT

Objective To study the expression of immunoglobulin-like transcripts 3 (ⅡT3) and ILT4 in peripheral blood dendritic cells (DC) of kidney transplantation recipients and to analyze its significance in immunity hyporesponsiveness of transplantation. Methods Twenty kidney allograft recipients who were survived more than five years were recruited to two groups: renal function stable groups, chronic rejection groups, and 10 healthy volunteers served as a control group. The peripheral blood mononuclear cells (PBMC) were stimulated with granulocyte-macrophage colony stimulating factor (GM-CSF) and interleukin 4 (IL-4) and immature DC were obtained. The expression of ILT3 and ILT4 was detected by using flow cytometry. The level of HLA-G5 in serum was determined by using enzyme linked immunosorbent assay. Results ILT3 expression in renal function stable group was increased and decreased in chronic rejection groups as compared with control group (P<0.05),but ILT4 expression had no significant difference among all groups. HLA-G5 in serum was significantly increased in renal function stable group as compared with other groups. Conclusion Expression of ILT3 and HLA-G was increased in the kidney transplantation recipients with stable renal function and long-term survival, suggesting that they may play an important role in inducing and maintaining periphery immune tolerance.

ABSTRACT

Objective To investigate the effects of HLA matching on long survival of patients with kidney transplantation. Methods In 2508 cases of renal transplants, based on Ag M standard, in 0 MM-6 MM (7 groups), the effects of HLA matching on the survival rate of 1 year, 5 years and 10 years, and the incidence of renal acute rejection (AR) in renal allografts were analyzed. Results Only 7 cases had 0-missmatches, and most cases had 2 or 3 missmatches. In the group of zero antigen mismatches, the incidence of renal AR was 5 %, lower than other groups (P<0. 01); in the group of six antigen mismatches, the incidence of AR was 23 %, obviously higher than other groups (P<0. 01). The 1-year, 5-year and 10-year survival rate was 97 %, 90 %, 88 % in the group of zero antigen mismatches; 94 %, 86 %, 83 % in the group of one antigen mismatches; 94 %, 84 %, 82 % in the group of two antigen mismatches; 93 %,85 %, 81% in the group of three antigen mismatches; 91%, 82 %, 74 % in the group of four antigen mismatches; 90 %, 81%, 72 % in the group of five antigen mismatches; 88 %, 80 %, 70 % in the group of six antigen mismatches. Conclusion Good HLA matching can significantly reduce the incidence of AR of renal allografts and increase the survival rate. If recipients are offered to choose those with HLA antigen mismatches ≤3, it is good for the effective use of donor kidneys, the prevention of rejection, and the improvement of the transplantation results.

ABSTRACT

OBJECTIVE@#To introduce clinical experience for living-related donor kidney transplantation (LDKT) by reviewing LDKT clinical data.@*METHODS@#A total of 158 patients underwent LDKT. Expect for 7 patients donated by their spouses, the others had blood relationship donors. Donor-recipient HLA matching showed 2 patients had 5-loci mismatch, 5 with 4-loci mismatch, 88 with 3-loci mismatch, 50 with 2-loci mismatch, 12 with 1-loci mismatch, the other 1 with 0-loci mismatch. All of the 158 donors underwent open nephrectomy, 35 of whom donated the right kidneys and the other 123 donated the left kidneys. Triple immunosuppressive regimen consisted of calcineurin inhibitors or FK506, MMF or AZa, and steroid.@*RESULTS@#All donors were healthy after the operation. All donors were followed up for 6 to 12 months and blood exams showed that inosine levels were normal. The longest kidney transplant functional survival time was 10 years to up June 2008. The one year patient/graft survival rate was 95.5%. Delayed graft function (DGF) occurred in 5 patients, 4 of whom recovered in 2-5 weeks. Five patients died, 4 of whom died of post-operational pulmonary infection within 3-5 months, with no transplantational complications. The other one died of pulmonary bleeding during dialysis while treating for DGF. One patient received a second deceased kidney transplant because of hyperacute rejection during the surgery. Five developed acute rejection 1 month after the operation (incidence rate 3.16%), 4 of whom were cured by administration of methylprednisolone, and the other one returned to dialysis because of renal toxicity of cyclosporine. Three patients had positive chronic rejection, 2 of whom lost graft function in 1.5-3.5 years. Eight patients developed pulmonary infection and 4 of them were cured.@*CONCLUSION@#Sufficient LDKT pre-operational assessment, satisfactory tissue matching and reduced ischemia time may result in lower incidence of DGF, acute rejection and higher patient/graft survival rate. In LDKT, importance should also be attached to the prevention of DGF and graft rejection. Rational dosage of immunosuppressants is advocated to prevent secondary infective complications. Donor specifications and all around evaluation of the living-related donors should also be emphasized to minimize the harm to the donors. Long term follow-up is also essential to ensure donors' post-operational healthy life.

Objective:Effect of ICA (Icariin) was observed on immunosuppression mice caused by Cyclophosphamide(Cy).Methods:A total of 60 mice,expect control group mice,were injected Cy intraperitoneally [300 mg/(kg·d)],then randomly divided into modelgroup(saline),positive (shenqi,1 ml/d)groups,ICA groups[150,80,40 mg/(kg·d)].Saline,shenqi and ICA were perfused respectively for 10 successive days;All mice were sacrificed after 12 h of last administration for performing following experiments.Measuring SI and TI and calculating amounts of lymphocyte from spleen and peripheral blood;Proliferative reaction of splenic lymphocyte stimulated by ConA and LPS were detected by MTT assays.Killing activity of NK and CTL cells for colon26 and level of TNF-α production were measured by LDH method.Ratios of CD3~+ T and NKT in splenic lymphocyte (SPL) were studied by FACS.Results:ICA can recovery TI and SI of mice to normal level and boost the population of splenic lymphocyte (SPL) (P<0.01).After treatment with ICA,activities of NK cell and CTL cell were significantly improved,and the level of TNF-α was significantly elevated.The ratios of NKT and CD3+T in the ICA-treated group were increased obviously (P<0.01).Conclusion:ICA can enhance immunological function and alleviate the side effect of chemotherapy effectively.
