Objective To summarize the experiences and protocol of extracorporeal membrane oxygenation (ECMO) technique in donors with brain death and unexpected cardiac arrest.Method We described here the organ donation of one case of brain death complicated with hemodynamic instability and cardiac arrest,and the corresponding recovery of the receptor liver.A 50-year old female developed brain death due to brain aneurysmal hemorrhage.He was given two kinds of high-dose vasopressor,but hemodynarnic instability was not improved.After ECMO support,the hemodynamics turned to stable,but unexpected cardiac arrest happened.The total operating time of ECMO was 5 h,including 4 h after cardiac arrest.The liver was transplanted into a 65-year old female with hepatocellular carcinoma (diagnosed by Hangzhou Criteria) by classic orthotopic liver transplantation with end-to-end anastomosis.Result One liver and two kidneys were obtained successfully,and all the receptors recovered uneventfully.The post-operative ALT and AST levels reached the peak at 169 U/L and 365 U/L respectively,and returned to normal two weeks later.Conclusion ECMO can be used to support brain death complicated with hemodynamic instability and unexpected cardiac arrest.It can save precious time for organ donation,and preserve the function of liver and kidney as well.

Objective To explore the efficiency of the ABC-HOME in the rapid identification and assessment of potential donors.Methods We developed a submit system and a rapid assessment method of ABC-HOME for potential donors at 2013.They were on trial in service area hospitals of Guangzou General Hospital Organ Procurement Organization (GHOPO) from February,2015.We reviewed medical records of potential donors occurring in the intensive unit at 2014,from February to December 2015 and 2016,respectively.We examined data on the number of potential donors,actual donors and beds of ICU,and calculated the number of potential donors and actual donors per bed per year.The reasons for donation failure were analyzed.Results 19,38 and 50 organ donations were realized in 243,474 and 513 potential donors in 2014,from February 2015 to December 2015 and 2016,respectively.The growth rate of organ donation and the number of actual donors per bed per year was 95.0%,8.2% and 0.45,0.89 and 0.96,respectively.The conversion rate in these potential donors was 8.92% from February 2015 to December 2016.The reasons for donation failure included the family and social factors,doctor-patient relationship and communication factor and illness condition of donors' factors.Conclusion ABC-HOME is a convenient assessment method for potential donors,which can help to promote the identification of potential donors and to increase the number of potential donor information.

OBJECTIVETo investigate the relationship between the second to the fourth digit ratio (2D:4D) and body mass index (BMI) in infertile men of the Han ethnic group in Ningxia.

METHODSUsing anthropometry, we calculated the mean ratio of 2D:4D and BMI of 197 infertile men and 148 normal healthy male controls, followed by analysis of their relationship.

RESULTSThe BMI was correlated positively with the 2D:4D ratio of the left hand in the infertile men (P < 0.05) and in the patients with a higher 2D:4D ratio of the left hand (P < 0.05), but negatively with the 2D:4D ratio of the righ/left (Dr-1) (left: P < 0.01; Dr-l: P < 0.05). The mean 2D: 4D ratio and BMI were both lower in the normal control than in the infertile men, with statistically significant differences in BMI (P < 0.05) and the 2D:4D ratio of the left hand (P < 0.05).

CONCLUSIONThere is a correlation between the 2D:4D ratio and BMI in infertile men.

BACKGROUNDRheumatoid arthritis (RA) is a chronic, systemic autoimmune inflammatory disorder. Many methods have been used to observe the progress of RA. The purpose of this study was to observe the progress of RA in rats with 18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT), magnetic resonance (MR) imaging and arthritis score, and analyze the relationships among different methods in evaluation of RA.

METHODSSixteen healthy Sprague Dawley (SD) rats about 8-week old were randomly assigned to a RA group and a control group. Bovine type II emulsified incomplete Freud's adjuvant was used to induce arthritis in the RA group. Arthritis score of the rats in two groups were recorded, and (18)F-FDG PET/CT, MR imaging were performed both on the corresponding rats every 3 days. All the rats were sacrificed at week 5, and histopathological examination was performed on rat knees stained with haematoxylin and eosin.

RESULTSThe arthritis score and the standard uptake value (SUV) of knee joints in RA rats increased with the progression of arthritis gradually. Both peaks of arthritis score and SUV appeared at 21 days after the first immune injection, then the arthritis score and SUV of knee joints decreased slowly. The arthritis scores of knee joints in RA rats were positively correlated with their SUV changes. The MR images were confirmed by the histopathological studies.

CONCLUSIONPET/CT can detect the earliest molecular metabolism changes of RA, and MR imaging can follow up the dynamical anatomical changes of RA, all of which indicated that PET/CT and MR imaging may be applied as useful tools to monitor the progress of RA.

AIMTo identify a novel alternative transcript of the novel retinal pigment epithelial cell gene (NORPEG) expressed in the human testis.

METHODSA human testis cDNA microarray was established and hybridized with cDNA probes from human fetal testes, adult testes and human spermatozoa. Differentially expressed clones were sequenced and analyzed. One of these clones was a short transcript of NORPEG which we proceeded to analyze by RT-PCR.

RESULTSThe novel short alternative transcript of NORPEG was isolated and named sNORPEG. It was 3486 bp in length and contained a 2952-bp open reading frame, encoding a 110.4-kDa protein of 983 amino acids. Amino acid sequence analysis showed that the sNORPEG protein contains six ankyrin repeats and two coiled-coil domains. It shares a high homology with the NORPEG and ankycorbin proteins in both its sequence and motifs. Blasting the human genome database localized sNORPEG to human chromosome 5p13.2-13.3. Expression profiles showed that sNORPEG was expressed in human fetal testes, adult testes and spermatozoa. Moreover, sNORPEG was found to be ubiquitously expressed in human tissues.

CONCLUSIONsNORPEG is expressed in different developmental stages of the testis and encodes a protein that may have roles in human testis development and spermatogenesis.

OBJECTIVETo investigate the relationship between the -308G/A, -857C/T and -1031T/C of tumor necrosis factor alpha gene (TNF- alpha), -174G/C and -572C/G of interleukin-6 gene (IL-6) polymorphisms and schizophrenia.

METHODSGenomic DNA was isolated from the venous blood leukocytes of 346 unrelated patients with schizophrenia and 323 healthy unrelated individuals (control group). All of the polymorphisms were genotyped by PCR-restriction fragment length polymorphisms (PCR-RFLP). Genotype and allele frequencies were analyzed by SPSS13.0 software.

RESULTSThere were significant differences in both allele and genotype frequencies of -857C/T of TNF-alpha gene between the schizophrenia and control groups (P< 0.05). The allele T of -857C/T in schizophrenia group was significantly higher than that in control group (chi-square was 9.414, P=0.002, OR=1.511, 95%CI:1.160-1.969). In addition, there were significant differences in the positive and negative syndrome scale (PANSS) total score and negative symptoms between the patients with different -857C/T genotypes, and the negative symptom score of TT genotype was significantly higher than that of CC genotype (P<0.05).

CONCLUSIONThere is an association between -857C/T of TNF-alpha gene and schizophrenia, individuals with T allele of -857C/T are susceptible to schizophrenia, and there is an association between -857C/T and negative symptom score.
