According to the character of scientific research administration. the nlain task of its innovation is to change administrator's concept. to make administrative management becoming service, as well as to enhance service consciousness. It is needed to establish high-qualified scientifie research administrative team with seeking truth from facts and human oriented concept. on the basis of the hospital administration. Meanwhile, improring continuously the administrator's quality is also important measure for adaptation of knowledge economic era

BACKGROUND:In recent years, interventional therapy because of its high success rate, good curative effect, little trauma has been widely recognized, but vascular intimal injury due to interventional therapy stil has no effective treatment, resulting in long-term postoperative severe restenosis. Stem cel transplantation has brought a new drawn for the repair of impaired endothelial function, reendothelialization and aided restoration of the blood supply to ischemic tissues. OBJECTIVE: To summarize the recent progress in umbilical cord blood stem cels transplantation and endovascular treatment for treatment of diabetic lower limb ischemic disease. METHODS: A computer-based search of PubMed and CNKI was performed for relevant articles published from January 2000 to March 2015 using the keywords of “umbilical cord blood stem cel transplantation, percutaneous transluminal angioplasty, diabetic lower limb ischemia, restenosis” in English and Chinese. Totaly 216 relevant literatures were initialy obtained, and 44 articles were ultimately included. RESULTS AND CONCLUSION:By comparing the therapeutic efficacy and long-term prognosis of umbilical cord blood stem cel transplantation and endovascular treatment, it is concluded that umbilical cord blood stem cel transplantation combined with endovascular treatment is better than either of them alone, which can promote the establishment of colateral circulation, improve the impaired endothelial function and reduce the occurrence of restenosis after interventional therapy.

Objective To evaluate the characteristics of the testicular torsion patients with the first symptom of acute abdominal pain.Methods From October 1998 to May 2014, 8 adolescent or boys with testicular torsion presenting acute abdominal pain instead of scrotal pain as their primary symptom were retrospectively reviewed.The average age was 12 (3-16) years.An acute abdominal pain presented firstly in all cases, which accompanied by nausea and vomiting in 4 cases, groin pain in 2 cases, fever in 1 case. In genital examination, the scrotum skin was red and swollen, while the testis was in transverse position and tenderness.The testicular and homolateral abdominal pain got worse when we pulled the involved testis. Doppler ultrasound examination revealed that the blood supply of the involved testis decreased or disappeared.Results In the 8 cases, 5 cases were not examined their testicles or scrotum during the first evaluation, which were found the testicular necrosis during the following exploratory surgery, and orchidectomy was performed. In the other 3 cases, external genital were examined during the first evaluation, and the scrotal and testicular abnormalities were detected.Doppler ultrasonography showed abnormality in testicular blood supply.Testicular torsion was proved during the emergent operation, and the 3 testes were salvaged.The mean duration time from symptom onset to operation was 4 h in the salvaged group, while the average time was 28 h in the orchiectomy group.The mean follow-up time was 18 ( 10-36) months.In the 3 cases whose testis was saved, 1 affected testis was atrophied, and the blood supply of the other two was good.No severe complications occurred in the other 5 cases.Conclusions Testicular torsion should be considered in adolescents and boys with acute lower abdominal pain.The routine external genital examination should be performed when a boy or adolescent complains of abdominal pain.

Objective To Study the antiarrhythmic effects of oryzanol.Methods Twenty rats were randomly divided into two groups:oryzanol group and control group,ten rats in each.The rats in the oryzanol group were fed with oryzanol which was mixed into normal diet at a dose of 60mg?kg -1 ?d -1 for 4 days.The rats in the control group were fed with normal diet.Results The responses to noise interference and adrenaline in the oryzanol group and control group were as follows:⑴the heart rates were 299?72 beats/min,351?68 beats/min(P

Objective to investigate the application of the whole course case tracking method in continuous improvement of nursing quality of out-patient operation unit. Methods Administration frames were established for this project,such as monitoring group and executive group. the medi-cal treatment procedure and patients′experience were followed by referees. the results were quantified for statistical analysis. the problems were rec-ognized by priorities and rectification was correspondingly performed. Afterward,another group of patients were traced to evaluate the results of the rectification. We focus on those items of lower scores and undertook rectifications accordingly. Particularly,we optimized signs in outpatient unit, made pamphlets to clarify the procedures,and were cautious to provide more easy-to-understand informs. Results By the second round evaluate, these scores were effectively improved. Especially,the item of“clear informed consent”was statistically significant(P = 0.003). Meanwhile,the team of outpatient operation unit became more cohesion,with enhanced service consciousness,and was initiative to improve the work. Conclusion the whole course case tracking method is feasible for short-range medical service evaluation such as outpatient surgery. the evaluation results clarify the direction for quality improvement,thus set the starting point of quality management aiming at continuously improvement of the patients′ experi-ence and quality of nursing service.

Objective·Giving the ovariectomized (OVX) mice exogenous estrogen replace therapy (ERT) so as to explore the inflammatory mechanism of estrogen in the pain modulation of OVX mice.Methods·Twenty-four 12-week-old female C57BL/6J mice were randomized into three groups:sham group (S),ovariectomy+placebo group (P),ovariectomy+estrogen group (E).The ERT began from one week after OVX and last for four weeks.Paw withdraw threshold (PWT) and paw withdraw latency (PWL) were measured at one day before OVX,and three days,one week,two weeks,three weeks,four weeks and five weeks after OVX.Concentrations of inflammatory cytokines in serum were measured at three days and five weeks postoperatively.Five weeks after operation,the lumbar intumescentia of spinal cord was taken and the expression of p38 was analyzed by Western blotting.Results·All the OVX mice's PWTs or PWLs were decreased after operation compared with non-operation mice;PWTs and PWLs were significantly different from group S separately from one week and three days after OVX (P＜0.01).The inflammatory cytokines of OVX mice were significantly higher than group S (both P＜0.01) at three days after OVX.Western blotting results showed that the p38 of group P was significantly higher than that of group S after five weeks postoperatively (P＜0.01).By receiving ERT,both PWTs and PWLs of group E increased slightly and were significantly different from group S (P＜0.01) at four and five weeks after OVX.At five weeks after OVX,inflammatory cytokines of group E were significantly lower than group P (P＜0.01) but still much higher than group S (P＜0.01).Meanwhile the content of p38 in group E was less than that in group P (P＜0.01).The p38 in group E was still more than group S,however it was no longer significantly different from group S (P＞0.05).Conclusion·Estrogen may reduce concentrations of inflammatory cytokines through the p38 MAPK pathway and plays an important role in the pain modulation of OVX mice.

The urothelium is a transitional epithelium which lines on the renal pelvis, ureter, bladder and proximal urethra adjacent to the bladder. It’s a permeability barrier. In the process of urothelial development or injury repair, the mature urothelial cells expressing uroplakin appears after the hierarchical transcription of a series of transcription factors in basal stem cells. Understanding normal urothelial differentiation process of the urothelial cells could be beneficial to uncover the development of urothelial carcinoma so that to provide targeted therapy options and the study of the urinary tract repair process after injury. In addition, the study of stem cell differentiation microenvironment also provides important theoretical support for tissue engineering and tissue reconstruction. In this review, we discuss the latest findings on urothelial cell differentiation and its clinical significance.

Objective To investigate the influencing factors involved in the long-term effect after interventional treatment of diabetic lower extremity vascular disease.Methods The data of 358 diabetic patients with lower extremity vascular disease were collected retrospectively.The ankle-brachial index (ABI) values at the 6th, 12th and 24th month after interventional treatment were documented and the factors may influence ABI value werc analyzed.Results Single factor analysis showed that after 24 months treatment, the proportion of ABI＜0.5 (severe ischemia) in the patients combined with obesity, smoking, older age were 15.0％ (31/206), 18.4％ (25/136) , 12.1％(19/157) ,7.5％(15/200) ,while non obesity,younger age,no smoking,no hypertension were 6.6％ (10/152), 14.8％ (33/222), 6.5％ (13/201), 1.9％ (3/158), and the differences were significant (P ＜0.05).Logistic regression analysis showed that old age (OR =1.341,95％ CI: 1.281-1.496, P =0.045), smoking(OR=2.301,95％ CI: 1.903-4.844,P=0.028) and obesity(OR=1.299,95％ CI: 1.270-1.588,P =0.038) were the independent factors influence the long-term therapeutic effects on diabetic lower extremity vascular disease.Conclusion Obesity, smoking, old age are the main factors influence the long-term therapeutic effects on diabetic lower extremity vascular disease.

Objective To observe the effect of drug combinations on the blood flow after reduction of the testicular torsion in rabbits.Methods From October 2014 to June 2015,36 male rabbits (weighing 1.8-2.4 kg,10-14 months of age) were randomly divided into experimental group and control group,18 in each group.Produced by surgical testicular torsion model (720° counterclockwise rotation of the left side testicle),every rabbit was accepted surgery reset after 9 hours and found all twisted testicles were dark.After fomentation with warm salt water,all the testicles were observed no significant improvement in colors,and no fresh blood flow after opening tunica albuginea,then all the testicles were retained and fixed.Low molecular dextran(5 ml/kg,ear marginal vein injection,1/d),papaverine(1.5 mg/kg,intramuscular,3/d) and low molecular weight heparin sodium (200 IU/kg,subcutaneous,l/d) were applied to promote testicular revascularization for 5 days in experimental group,and penicillin (40 000 U/kg,intramuscular,1/d) for 7 days.Control group was only given penicillin (40 000 U/kg,intramuscular,1/d) to prevent wound infection.Then Color Doppler ultrasound was used to observe the testicular blood flow siganals that were divided into 0,1,2,3 classes.Class 2 and class 3 could be considered as testicular survival.After each scrotum was opened,according to color,texture of testicle and whether the fresh blood flowing out when tunica albuginea was opened,to determine whether the testicle was alive.The testicle was ruddy,flexible,and fresh blood was observed,which could prove testicular survival.Results In experimental group,the testicular blood flow siganals:0 class 4 cases,1 class 3 cases,2 class 4 cases,3 class 7 cases.In control group,the testicular blood flow siganals:0 class 9 cases,1 class 2 cases,2 class 4 cases,3 class 3 cases.Surgical exploration found 11 cases of testicular survival in experimental group and 7 cases in control group,which was significantly difference (P ＜ 0.05).Conclusions The combined application of low molecular dextran,papaverine,low molecular weight heparin sodium can promote the recovery of testicular blood after reduction of testicular torsion,and improve testicular survival rate.

Objective:To analyze the results of syphilis specific serological tests among entry personnel in Beijing port during year 201 2 -201 4 in order to provide evidence for the prevention and control of syphilis.Methods:Demographics data and syphilis specific test results of entry personnel were obtained from the information system of Beijing International Travel Healthcare Center and input into Excel 201 6. Database for entry personnel was built up accordingly and was analyzed by IBMSPSS22.0.Results:The number of entry personnel in Beijing port during year 201 2 -201 4 was 1 06 302 person-time.According to the evaluation criteria,71 308 persons were recruited and analyzed,of whom 277 were tested serologi-cally positive and the total prevalence was 0.39% (95% CI:0.34% -0.43%).The prevalence was highest in the persons aged 40 -49 years (0.81 %)and was higher in males (0.50%)than in females (0.23%).The persons from Africa held higher prevalence (1 .27%)than from other five regions.As multivariate logical regression analysis indicated that the risk of syphilis infection was 1 0.38 times more in the persons aged 40 -49 years than in the persons <20 years (95%CI:5.59 -1 9.28),and 1 .85 times more in males than in females (95%CI:1 .40 -2.44).For the people from Africa,South America and Asia,the infection risks were respectively 4.89 times (95%CI:2.97 -8.06),4.82 times (95%CI:2.39 -9.74)and 1 .72 times (95%CI:1 .1 5 -2.59)more than that for the people from North Ameri-ca.Rising trend of the prevalence was observed in both genders by age groups (P value for trend χ2 <0.05).Except for Asia,the prevalences of the people from other five regions were rising slightly by years,however there were no obvious trends (P value for trend χ2 >0.05).Twenty-seven seropositive cases were found within 6 246 entry persons who were tested repeatedly during the research period,9 of which were seroconversion cases so that the cumulative conversion rate was 0.1 4% (9 /6 228).The average conversion time was (6.3 ±3.0)months.There was no statistical significance between the cu-mulative seroconversion rates of the persons with different genders and nationalities (P of Fisher’s exact test >0.05).Conclusion:Serological detection of syphilis for entry personnel in Beijing port and syphi-lis-related health education should be reinforced to reduce the risk of disease importing and spreading, protect susceptible subjects and promote health.
