The modest pressure promotes the graduate to keep continuous energy and focus on scientific research,but too much pressure will lead to mental problem and serious moral shortcoming.Reformation of scientific evaluating and promoting system,enhancement of scientific interest and reconstruction of mental training system should be the important ways to release the pressure of scientific research of the graduate.

Objective To study effect of racing training on 54 paraplegic ability of driving wheel-chair. Method 54 paraplegics paticipated in the wheel-chair racing training. Result The subjects drived wheel-chair more powerfully and faster than before, and pushed up step and ramp easily. Conclusion Wheel chair racing training is an effective method of improving the driving ability.

This study tried to investigate the change in the glomerular filtration rate in initiation of a low-protein diet (LPD) in the elderly patients with diabetic nephropathy, and to elucidate whether this initial phenomenon is reversible or irreversible. 24 non-insulin-dependent diabetic patients with renal failure patients were randomized to LPDⅠgroup (0.6g *kg-1*24h-1), LPDⅡgroup (0.8g*kg-1*24h-1), and NPD group for four weeks (phaseⅠ). Between weeks 4 and 8, all patients received NPS (phaseⅡ). Dietary protein intake (g*kg-1*24h-1), SCr, Ccr, albuminuria excretion rate and arterial blood pressure were measured at baseline and after four- and eight-weeks of follow-up, respectively. During phaseⅠ, a significant decline in dietary protein intake, Ccr, Scr, and albuminuria excretion rate were observed in the LPDⅠgroup and LPDⅡgroup. There was not any change in the NPD group. Conversely, during phase Ⅱ, with a significant increase in dietary protein intake, Ccr, Scr and albuminuria excretion rate increased in LPDⅠ group and LPD Ⅱ group compared with the NPD group. It suggested that dietary protein restriction for four weeks induces a reversible decline in GFR, Scr and albuminuria excretion rate in noinsulin-dependent diabetic nephropathy patients with renal failure, whereas systemic blood pressure remains unchanged.

Objective To explore the influencing factors of hypertensive cerebral hemorrhage in 68 patients with supratentorial prognosis of recovery of neurological function.Methods Clinical data of 68 patients with high blood pressure treatment supratentorial intracerebral hemorrhage,and brain CT,laboratory data were retrospectively analyzed.Neurological functions and related indicators change of were daalyzed by univariate and multivariate Logistic regression analysis.Results Gender,systolic blood pressure,diastolic blood pressure,red blood cell count,such as the impact on the prognosis was not statistically significant(all P ＞ 0.05) ; median line offset,nosocomial infections,surgery,gastrointestinal bleeding,heart failure,treatment Barthel index(BI) were a significant influence on the prognosis (all P ＜ 0.01).The median line offset,nosocomial infections,bleeding,gastrointestinal bleeding,heart failure,BI integration were the main factors affecting the prognosis of neurological function recovery.Conclusion The factors which affects nerve function recovery is an important part of improving neurological outcomes.We should emphasize them.

Objective To compare the effects of early and conventional instillation of normuscle invasive bladder cancer after transurethral resection of bladder tumor.Methods The clinical data of 32 patients with normuscle invasive bladder cancer were retrospectively analyzed.They were divided into observation group (16 cases) and control group (16 cases).The clinical effects of the two groups were compared.Results The recurrence rate of two groups was significantly different (x2 =3.864,P ＜ 0.05).The average recurrence time of two groups was significantly different (t =6.389,P ＜ 0.05).The incidence rate of adverse reactions (x2 =0.369,P ＞ 0.05) and the incidence rate of toxic reactions(x2 =2.222,P ＞ 0.05) in two groups had no statistically significant differences.Conclusion It can lower the recurrence rate for early and conventional instillation of normuscle invasive bladder cancer after transurethral resection of bladder tumor and to delay the recurrence time,so it is widely applicable for clinic cure.

HbA1C has been used clinically since 1980s as the index of glycemic control in individuals with diabetes mellitus.Several significant clinical trials demonstrated that the intensive blood glucose control reduced the chronic complications in diabetes.In recent years,HbA1C has been recommended as one of the diagnostic criteria for diabetes mellitus.However,the standardization of HbA1C measurement still remains to be an important and arduous task in China.

ObjectiveTo evaluate the efficacy and safety of ibutilide for conversion of paroxysmal and persistent atrial fibrillation.Methods31 patients with atrial fibrillation duration less than 90 days were included into amiodrone or ibutilide group.16 patients were intravenously administer with amiodrone and 15 patients with ibutilide separately.Conversion rate,time needed to converse and adverse effects were compared between two groups.ResultsThe total conversion rate of ibutilide group was significantly higher than that of amiodrone group (66.7％ vs 37.5％,x2 =1.98,P ＜ 0.05 ).Time needed to converse was significantly shortened in ibutilide group compared with amiodrone group [ ( 31.75 ± 7.39 ) min vs ( 51.87 ± 9.26 ) min,t =3.67,P ＜ 0.05 ].No clinical significant adverse effects were observed in ibutilide group.ConclusionIntravenous administration of ibutilide in cardioversion of paroxysmal and persistent atrial fibrillation was more safe and effective than amiodrone.

Objective To study the effect of improved laparoscopic techniques on ability of control urine in patients with prostate cancer.Methods 96 patients with prostate cancer were randomly divided into two groups,the observation group(51 cases) and the control group(45 cases).The patients in the control group were operated through the conventional treatment,while the patients in the observation group were operated through the improved laparoscopic technique,which protected the external urethral sphincter,reserved urinary nerve and reconstructed the bladder neck.The ability to control urine for 30,60 and 90 days were compared between two groups.Results The time of operation and bleeding of operation had no significant differences between two groups (all P ＞ 0.05).There were significant differences between two groups in indwelling catheter time and the ability to control urine for 30 ;60 and 90 days (t=10.0359,P＜0.05;t=7.9746,14.0205,10.8445,all P＜0.01).Conclusion Improved laparoscopic technique can improve the ability of control urine in patients with prostate cancer after operation.

Objective To investigate the early diagnosis and preventive measures for gestational hypertensive patients with heart disease.Methods Clinical data of 56 gestational hypertensive patients with heart disease were retrospectively analyzed.Results Aggressive treatment of maternal deaths occured in 1 case,2 cases of stillbirth,and the other 55 cases had good maternal prognosis.Conclusion Treatment of hypertensive heart disease in pregnancy should be based on the strong heart vasodilator,diuretic,caution magnesium sulfate.In the control of heart failure after 6-8h,shall terminate the pregnancy.Active treatment of the primary disease,to correct anemia and hypoproteinemia,early diagnosis of heart failure and strictly control expansion of indications can help to improve the prognosis of hypertensive heart disease in pregnancy.
