Objective To analyze the outcomes of renal transplantation from donation after citizen death (DCD) in our single center.Method We retrospectively investigated the recipient outcomes of renal allografts from DCD.Between November 2010 and 31st December 2014,our institution performed 242 renal transplants from DCD.Outcome variables (survival of recipients/allografts and adverse events) and characteristics of marginal donor transplants were analyzed.Result There were 139 males and 44 females in the enrolled 183 donors,and the range of age was from 2 days to 68 years.183 donors included 102 cases of donation after brain death (category Ⅰ),22 cases of donation after circulatory death (category Ⅱ) and 59 cases of donation after brain death followed by circulatory death (category Ⅲ).Utilizing these renal allografts,we performed 242 kidney transplantations including 237 single kidney transplants and 5 pediatric en bloc kidney transplants.The age of recipients ranged from 12 to 64 years.The data indicated that the 1-year recipient/allograft survival rate was 93.8％ and 90.5％,respectively.The rate of delayed graft function (DGF) was 33.1 ％,higher than that from executed prisoners allografts (23.6％,P＜0.05).However,the rate of 1-year acute rejection,interstitial pneumonia and the other adverse events (urinary fistula,ureteral obstruction and cardiac and cerebral vascular accident,etc.) was similar to that from executed prisoners allografts.In addition,good results from pediatric and elder donor renal transplantation were shown in our data,even though the discard rate of elder donor kidney was high.Conclusion By comprehensive evaluation,strictly screening donors and enhancing the rnanagenent of donors,the long-term survival of recipients may be prolonged and the incidence of DGF and primary graft non-function (PNF) may be decreased.The marginal donors from pediatric and elder DCD donors could be utilized in clinical transplantation safely and effectively as long as reasonable evaluation was carried out.

Objective To study the clinical result of the surgical treatment of upper cervical vertebra disease from high anterior cervical retropharyngeal approach.Methods Among 14 patients,there were 7 C_(2.3)disc hernia- rions combined with C_(2.3)dislocations,3 Hangman fractures,2 odontoid process fractures and 2 C_3 tumors.All patients underwent the high anterior cervical retropharyngeal approach.10 cases were given discectomy of C_(2.3)or focus clear- ance of C_3,iliac bone autograft or titanium cage filled and internal fixation with titanium plate.2 cases of odontoid process fractures were given anterior screw fixation.Results 14 cases got successful exposure.The decompression, reduction,lesion clearance and fusion with internal fixation were done in all patients.There were no important vascu- lar or nerve injuries.The surgical treatment could improve the spinal cord nerve function to a certain degree for the cases with compression of spinal cord.Conclusion Good exposure of upper cervical spine and effective surgical oper- ation could be achieved from high anterior cervical retropharyngeal approach,with minimal trauma and complication, and it was a favorable approach.

ObjectiveTo investigate the effect of Du meridian electroacupuncture of the scalp on deglutition disorder after stroke.Methods67 patients with deglutition disorder after stroke were randomly divided into the experimental group (n=34) and control group (n=33). The patients of the experimental group were received Du meridian electroacupuncture of the scalp as main therapy, combined with routine medicine treatments; the patients of the control group were only received routine medicine treatments. Before and after treatments, deglutition function of all patients was assessed by drinking water test and clinical effect was also assessed.ResultsAfter treatment, the deglutition function of the patients in the experiment group was markedly improved and superior to those in the control group ( P<0.01).ConclusionDu meridian electroacupuncture can markedly improve the clinical effect of routine medicine treatments on deglutition disorder after stroke.

OBJECTIVETo evaluate therapeutic effects of Rigidfix cross pins combined with Intrafix pins for the reconstruction of anterior or posterior cruciate ligament under arthroscopy.

METHODSFrom January 2009 to June 2010,34 patients with anterior or posterior cruciate ligament injuries were divided into two groups : group A and group B. There were 24 patients in group A, including 19 males and 5 females,with an average age of (31.83±9.57) years old. The patients in group A were treated with anterior cruciate ligament reconstruction under arthroscopy; Rigidfix cross pins and Intrafix pins were used to fix femoral and tibial side respectively. Among the 10 patients in group B, 8 patients were male and 2 patients were female, with an average age of (27.20+7.59) years old. The patients in group B were treated with posterior cruciate ligament reconstruction under arthroscope; Intrafix pins and Rigidifix cross pins were used to fix femoral and tibial side sepectively. The drawer test and Lachaman test were used to evaluate postoperative knee stability. All the patients were followed up at least 18 months. Lysholm and Tegner knee scores were used to evaluate the clinical therapeutic effects.

RESULTSAll the 34 patients were followed up, and the duration ranged from 18 to 26 months,with an average of (20.79±2.39) months. All the patients obtained good pain relief and knee stability. In group A,Lysholm scores significantly increased from 43.04±7.57 preoperatively to 85.41±4.68, 92.50±3.05, and 93.45±2.57 at 6,12, and 18 months postoperatively; Tegner scores significantly increased from 2.62±0.92 preoperatively to 7.45±1.14, 8.58±0.77, and 8.95±0.55 at 6, 12, and 18 months postoperatively. In group B,Lysholm scores significantly increased from 46.20±8.27 preoperatively to 86.40±5.14,90.40±2.67,and 92.00±3.85 at 6,12,and 18 months postoperatively ;Tegner scores significantly increased from 2.00±0.66 preoperatively to 7.10±0.99, 8.60±0.84, and 8.80±0.42 at 6,12, and 18 months postoperatively. There were no differences in Lysholm and Tegner scores between group A and B at different times during follow-up. Lysholm scores of all patients significantly increased from 43.97±7.79 preoperatively to 85.70±4.76,91.88±3.06,and 93.02±3.01 at 6,12,and 18 months postoperatively. Tegner scores of all patients significantly increased from 2.44±0.89 preoperatively to 7.35±1.09, 8.58±0.78, and 8.91±0.51 at 6,12,and 18 months postoperatively. During the follow-up period,there were no serious immunological rejection and complications.

CONCLUSIONReconstruction of anterior or posterior cruciate ligament under arthroscopy with Rigidfix cross pins and Intrafix pins fixation is feasible therapy for anterior or posterior cruciate ligament injuries, and the fixation is rigid. The therapy restores knee stability and provides a satisfactory short-term results.

The growth changes of glutathione (GSH) and ergosterol in Saccharomyces cerevisiae (CICC1447 and CICC1339) were detected under 0.5Mpa pressure with compressed high-pure air (O-2∶N-2=21∶79). The results showed that logarithmic phases of the two strains were delayed; their biomass and special growth rate were lower than those of control sample (0.1MPa) and the double time were prolonged under 0.5MPa. High-pressure could increase the content of GSH obviously, compared to ambient atmosphere control samples. When the holding time was 3h, the content of GSH and ergosterol in CICC1447 increased 42.6% and 20.1%, respectively. However, the content of GSH in CICC1339 increased 58.7% when the holding time was 6h, while ergosterol content reduced. The results indicated that different yeast strains have different stress-response mechanism to copy with high-pressure shock.

Objective To determine chromosomal localization of the primary gout susceptibility gene in a pedigree.Methods The clinical data and the peripheral blood samples were collected in the pedigree members and the genomic DNA was extracted from peripheral blood.A genome-wide screening was performed using 400 micro-satellite DNA markers in this family,and linkage analysis was used to determine the chromosomal location of the primary gout susceptibility gene.Results Linkage analysis showed that the maximum LOD score reached 1.50 at marker D4S1572 (at recombination fraction?=0.00).Conclusion Since D4S1572 is localized at 4q25,the primary gout susceptibility gene of this pedigree is localized at 4q25.

Objective To explore the association of Gly71Arg mutation in gene of bilirubin uridine 5'-diphosphate-glucuronosyltransferase(UGT1A1)and neonatal jaundice in Beijing city Han population.Methods The genotypes and alleles of the Gly71 Arg polymorphism for UGT1A1 gene were identified by polymerase chain reaction-restricted fragment length polymorphism assay in infants of Beijing city Han population of China,including 96 infants with neonatal jaundice[serum bilirubin(307.06?38.5)?mol/L,indirect bilirubin(292.9?35.9)?mol/L] and 101 healthy control infants [serum bilirubin(131.2?42.1)?mol/L,indirect bilirubin(126.3?39.7)?mol/L].The genotypes and allele frequencies of the polymorphism were compared between infants with neonatal jaundice group and healthy infant group(control group).The effect of polymorphism in infants with neonatal jaundice group on serum bilirubin level were analyzed.Results There were significant differences in genotypes distribution in Gly71Arg polymorphism for UGT1A1 gene between the 2 groups(?2=9.47 P=0.002).Compared with control group,neonatal jaundice group had significantly higher Arg allele frequency in the polymorphism for UGT1A1 gene(?2=10.34 P=0.001).There were independent effects of Gly71Arg mutation in the gene on serum bilirubin level in neonatal jaundice group,at the carriers of homozygote of the Arg allele of Gly71Arg polymorphism had higher serum bilirubin levels compared to carriers of heterozygote of the Arg allele of the polymorphism and non-carriers of the Arg allele of the polymorphism(Pa
