Objective To analyze the outcomes and postoperative complications of renal transplant recipients of ethnic minorities and Han population in China, and investigate the differences between them. Methods Clinical data from 89 minority patients and 100 Han patients who had received renal transplant of Hans' donators in Organ Transplantation Center of PLA from 1990 to 2012 were retrospectively analyzed. The general data before transplantation, and rate of short-term survival of the graft, incidence of delayed graft function (DGF), acute rejection, and pulmonary infection after transplantation were analyzed and compared. Results No statistical difference was found in the preoperative personal profile between the recipients of minorities and Han nationality. In the recipients of minorities and Han nationality, the 1-year graft survival rate was 89.9% and 92%, the respective incidence of DGF was 28.1% and 27.0%, and the respective incidence of acute rejection was 22.5% and 19.0%, and there was no significant difference between them (P>0.05). The incidence of pulmonary infection was higher in minority recipients (30.3%) than in Han recipients (10.0%, P<0.01), but no significant difference was found between Tibetan, Hui, Manchu and Mongolian recipients in 1-year graft survival rate, incidence of DGF, acute rejection and pulmonary infection (P>0.05). Conclusion The short-term clinical outcome of renal transplant recipients seems to be similar in different Chinese ethnic groups, but the incidence of pulmonary infection is higher in minority recipients, so it is important to strengthen monitoring in early postoperative period.

Sudden cardiac death (SC D ),m ostcom m only seen in coronary heart disease, is a kind of sud-den death caused by series of cardiac param eters, w hich usually com bines w ith m yocardial infarction. H ow ever, som e SC D s (including early m yocardial infarction) happen suddenly and cause death in a very short tim e. In these circum stances, typical m orphological changes are lack in m acroscopic or m icroscopic fields, w hich m ake such SC D s becom e the em phasis and difficulty in the present research. SC D caused by m yocardial infarction and abnorm alities of cardiac conduction system (C C S ) is related to atheroscle-rosis of coronary artery closely. T his paper review s cardiac dysfunction caused by m yocardial infarction and diseases of C C S from m orphology and m olecular biology, and explores potential relationship be-tw een them . T his paper aim s to provide clues to the m echanism of m yocardial infarction related sudden death and possible assistance for forensic diagnosis of SC D .

Objective To evaluate the protective effects of methylprednisolone combined with dexmedetomidine of cardiac valve replacement in patients with brain cognitive function under cardiopulmonary bypass (CPB).Methods Sixty patients for heart valve replacement in Affiliated Hospital.Inner Mongolia Medical University were randomly divided into four groups (n =15 each):group A control,methylprednisolone group (group M),dexmedetomidine group (Group D) and methylprednisolone combined with dexmedetomidine group (group B).After the induction of anesthesia,the patients were endotracheally intubated and mechanically ventilated.Methylprednisolone 20mg/kg was administered to the CPB circuit prime in group M.A loading dose of dexmedetomidine 1 μg/kg was pumped intravenously over 10 minutes after induction,followed by continuous infusion at 0.05μg/(kg · h) until the end of operation in group D.A loading dose of dexmedetomidine 1 μg/kg was pumped intravenously over 10 minutes after induction,followed by continuous infusion at 0.05μ g/(kg · h) until the end of operation and methylprednisolone 20mg/kg was also administered to the CPB circuit prime in group B.At the same time the equal volume of normal saline was given in group A.After induction (T1),CPB instantly (T2),CPB 30min (T3),l0min after CPB(T4),at the end of operation(T5),6h after CPB (T6),the jugular bulb venous blood samples were taken for testing the serum concentrations of interleukin-6 (IL-6),interleukin-10 (IL-10),S100βprotein and neuron-specific enolase (NSE) using the method of ELISA.Simplified mini-mental state examination (MMSE) is used to assess the cognitive function of patients in pre-operation and 2days,3days as well as 7days after operation.Results At T1-6,IL-6,S100 protein and NSE in group M,group D and group B were significantly lower than those in control group,IL-10 was higher than that in control group,and there was significant difference (P ＜ 0.05).In B group at all time points IL-6 、S100 protein and NSE were lower than those in other groups,IL-10 was higher than other groups,and there was significant differences (P ＜ 0.05).The incidence of postoperative cognitive dysfunction in group M,group D and group B was higher than that in control group,and the incidence of cognitive dysfunction in B group was lowest,and there were significant differences (P ＜ 0.05).Conclusion Methylprednisolone and dexmedetomidine can effectively reduce the concentration of IL-6,S100 protein and NSE in cardiopulmonary bypass,reduce brain injury and the incidence of postoperative cognitive dysfunction.The protective effect on cerebral injury is better when using dexmedetomidine combined with methylprednisolone under cardiopulmonary bypass (CPB).

OBJECTIVE:To develop the method for the determination of riluzole concentration in blood plasma.METH?ODS:Riluzole was extracted with diethyl ether.The residues were analyzed with a reverse phase HPLC system(Diamonsil TM C 18 column,250mm?4.6mm,5?m),with mobile phase of MeOH-0.03mol/L and NH 4 H 2 PO 4 (80∶20,V/V),UV detection wave length of265nm,flow rate of0.8ml/min.RESULTS:The linear coverage of Riluzole was5～1000ng/ml;the lowest detectable concentration was5ng/ml.The average recoveries of riluzole were99.51%,95.74%and97.12respectively.The within-day and between-day relative standard deviations were1.17%、6.48%(n=5)respectively.CONCLUSION:The met_ hod is sensitive,accurate,simple and reliable,and it can be applied to phamacokinetic studies.

In order to investigate the human cytomegalovirus (HCMV) infection, the mouse cytomegalovirus (MCMV) infected mice were experimentally studied. 6 to 8 week old female BALB/C mice with immunosuppression were selected to undergo the MCMV inoculations: intracranial inoculation and peritoneal inoculation. MCMV of the infected mice in various organs and tissues were detected by using beta-gal staining and in situ nucleic acid hybridization assay. The pathological changes were observed in HE staining paraffin-embedded sections. It was found that all the MCMV infected mice showed the retardation of growth and development, and feather looseness. Both intracranial inoculation of 10(4) PFU viruses or peritoneal inoculation of 10(6) PFU viruses resulted in the pathological changes, to some extent, of various organs and tissues in the mice. The pathological changes in liver were consistent with the amount of beta-gal staining positive cells, indicating the liver lesions were mainly caused by viral proliferation. It was also found that the viruses in the immunosuppressed mice subjected to intracranial inoculation could spread to whole body organs, while the viruses in the immunosuppressed mice subjected to intrapeitoneal inoculation couldn't spread to the brain, suggesting blood-brain barrier could prevent the virus from spreading to the brain.
