Objective To evaluate the clinical outcome and relative factors of intervention treatment for atherosclerotic renal artery stenosis in elderly patients.Methods The clinical data of 79 patients diagnosed as atherosclerotic renal artery stenosis by angiography and treated by revascularization were analyzed.Results There were 55(69.6%)successes and 24(30.4%)failures in decreasing blood pressure and 28(35.4%)successes and 51(64.6%)failures in improving renal function after intervention treatment.Predictors of favorable outcome of intervention treatment in decreasing blood pressure were related to lower urine protein,higher glomerular filtration rate,higher systolic and diastolic blood pressure before treatment,lower resistance index(RI)of renal artery,and no complication of cerebral vascular diseases.Predictors of favorable outcome of intervention treatment in improving renal function were related with percentage of angiographic stenosis,category of antihypertension and lower urine protein.The logistic regression analysis showed that the percentage of angiographic stenosis was the most important predictor of intervention treatment for blood pressure control,age and level of serum creatinine before intervention treatment were the most important predictors of intervention treatment for improving renal faction.Conclusion Percentage of stenosis(≥85%),age(133 ?mol/L)can be used as the predictors of therapeutic success for renovascular stenosis in older patients.

OBJECTIVETo evaluate the clinical value of transoesophageal echocardiography on periventricular closure of ventricular septal defects (VSD).

METHODSTransoesophageal echocardiography (TEE) was performed in 27 patients with VSD diagnosed by the transthoracic echocardiography examination (TTE) and prepared to receive periventricular closure of VSD for the purposes of choosing the appropriate occluder before VSD closure and guiding occluder release during the operation and evaluating the post operative effects of VSD closure 1 week post operation.

RESULTSThree patients with VSD not suitable for periventricular VSD closure according to TEE results were not operated, periventricular closure of VSD were successfully performed in 20 patients and minimal residual shunt was seen in 1 patient post operation, periventricular closure of VSD failed in 4 patients and these patients received surgical closure. TEE at 1 week post successfully with periventricular closure of VSD in the 20 patients showed that there were no residual shunts and the pulmonary artery pressure was significantly lower post operation compared to that of preoperation value.

CONCLUSIONTEE is helpful in choosing the suitable patients and occlude size, guiding occlude release and evaluating the post operative results for periventricular closure of ventricular septal defects.

With the advancement of manned space science and technology,the scope of human exploration into outer space has been gradually expanded.The time and distances that astronauts flight on-board are becoming longer and longer.However,long-term microgravity can negatively affect astronauts' physical and psychological aspects,thus influencing their health and leading to the failure of work tasks,and even threatening their lives.This paper reviews USA,Russia and Europe research results in the field of astronauts on-board physical training methods and health protection measures,with the purpose of learning from their successful experience.Overall,it is suggested that for cross complementation in sport science,we should make the introduction of advanced and successful training systems to solve problems existing in astronauts on-board training,ensuring the maintenance of health.

OBJECTIVEImpulsivity is one of the core symptoms of children with attention deficit hyperactivity disorder (ADHD). In order to understand the neuromechanism of the impulsive behaviors in ADHD children, this study investigated the specific functional areas of the brain by functional MRI.

METHODSThe subjects consisted of 10 ADHD children with impulsivity, 7 ADHD children without impulsivity and 9 normal children. A functional MRI examination was performed when the subjects were instructed to finish GO and STOP tasks with the GO-STOP impulsivity paradigm. The MRI data during the two tasks of GO and STOP were averaged and the corresponding activation regions between groups were compared.

RESULTSThe data from the GO task revealed that the main activation regions of the normal children included frontal pole (superior frontal gyrus, middle frontal gyrus and medial frontal gyrus); the main activation regions of ADHD children without impulsivity were cerebellum (posterior lobe and anterior lobe bouton) and cingulated gyrus; those of ADHD children with impulsivity were medial globus pallidus and insula. The data from the STOP task showed that the main activation regions of normal children included superior frontal gyrus and middle frontal gyrus; those of ADHD children without impulsivity were middle frontal gyrus and cingulate gyrus; those of ADHD children with impulsivity were uncus and putamen. The activation regions of ADHD children with impulsivity were much fewer than the other two groups.

CONCLUSIONSThe behavior of impulsivity-control involves a number of specific functional areas in the cerebral cortex. Compared with normal children, ADHD children without impulsivity have weaker brain function and brain activation, and ADHD children with impulsivity demonstrate much fewer brain activation regions, worse brain function and little awareness of the cerebral cortex.

OBJECTIVETo construct eukaryotic expression vector of the truncated septin2 and investigate the influence on the cultured mouse epidermal cell and fibroblast in vitro exerted by the transgenic expression product.

METHODSThe short splicing fragment was obtained by amplifying the reverse transcription product of the fetal mouse skin mRNA with PCR. Then its recombinant expression vector pcDNA3.1 (-)/septin2s was constructed and used to transfect the mouse epidermal cell and fibroblast cultured in vitro. The expression of the foreign gene was detected with RT-PCR and the changes of cell proliferation were observed and analysed.

RESULTSRT-PCR results indicated that pcDNA3.1/septin2 was expressed in the cultured mouse epidermal cells and fibroblasts in vitro. We found that the epidermal cells accelerated their reproduction, but the fibroblasts had no obvious changes.

CONCLUSIONWe successfully constructed eukaryotic expressive vectors of pcDNA3.1/ septin2s and transfected it into mouse epidermal cells and fibroblasts in vitro. The results settle a basis for showing effect of septin2s on fetal mouse skin.

OBJECTIVETo compare the difference of therapeutic effects between vessel pricking therapy and Prednisone for treatment of Henoch-Schonlein purpura nephritis.

METHODSSeventy cases of acute purpura nephritis syndrome were randomly divided into an observation group (40 cases) and a control group (30 cases). Patients in observation group were differentiated into sthenia and asthenia syndromes. Vessel pricking therapy was applied at Hegu (LI 4), Quchi (LI 11), Xuehai (SP 10) etc. by triangular needle for sthenia symptom; shallow needling was used at Pishu (BL 20), Shenshu (BL 23), Zusanli (ST 36) etc. by filiform needle. The control group was treated with oral admi-nidtration of Prednisone. The symptom score of TCM, 24 h urinary protein, red blood cell count of urinary sediment of both groups were observed before and after treatment and therapeutic effects were compared.

RESULTSThe total effective rate of 92.5% (37/40) in observation group was superior to that of 80.0% (24/30) in control group, and there was a significant difference between two groups (P < 0.05); the symptom score of TCM, 24 h urinary protein, red blood cell count of urinary sediment were all improved in both groups after treatment (all P < 0.05), and moreover, the improvement in observation group was superior to that of control group (all P < 0.05); after treatment, the symptom score of TCM of sthenia syndrome was lower than that of asthenia syndrome in observation group (P < 0.05).

CONCLUSIONVessel pricking therapy has a significant therapeutic effect for treatment of Henoch-Schonlein purpura nephritis, superior to that of oral administration of Prednisone, and the therapeutic effect is better for treating sthenia syndrome than for asthenia syndrome.

To obtain the recombinant pZP3alpha protein for the study of the contraceptive vaccines, the DNA sequence (446-1423) encoding purified pZP3alpha was inserted into a vector--pPICZalphaA. The recombinant plasmid pPICZalphaA-pZP3alpha was linearized and then transformed into Pichia pastoris GS115 by electroporation. Engineering strains were attained by screening with zeocin and induced to produce rpZP3alpha in high-density fermentation. Then rpZP3alpha was purified by Cu2+ metal affinity column chromatography from the separated and concentrated fermentative supernatants. The purified rpZP3alpha was identified by SDS-PAGE and Western blot, and the quantity, purity and rate of recovery of the rpZP3alpha were analyzed by Quantity One software. One male rabbit was immunized with the Cu-NTA-purified rpZP3alpha. The antibody responses against rpZP3alpha and porcine ZP were detected by ELISA and the indirect immunofluorescence. Engineering strains expressing rpZP3alpha in secretion were constructed. A 46kD component named rpZP3alpha which can react with anti-pZP3 antibody was purified from fermentative supernatants of engineering strains and the average yield of purified rpZP3alpha obtained from fermentative supernatants was 8mg/L. The purity and the rate of recovery were up to 92% and 63% respectively. The anti-rpZP3alpha antiserum was prepared by immunization of a male rabbit with purified rpZP3alpha. This anti-rpZP3alpha antiserum could react with rpZP3alpha and purified pZP3 in ELISA and bind to porcine zona pellucida which produced bright green fluorescence in the indirect immunofluorescence. The rpZP3alpha (46kD) protein could be successfully expressed in the Pichia pastoris expression system. And this protein retained the immunogenic activity of natural pZP3.
