Diabetic retinopathy (DR) is a common complication of eye in diabetics and is one of the major causes of blindness in adults.The current treatments of DR include surgery and laser therapy,but this does not fundamentally cure DR.Recent studies have found that mesenchymal stem cells (MSCs) for cell therapy to DR have a wide range of applications.MSCs have regenerative potential and play a role in the repairment of the retina,but the survival and homing ability of MSCs are poor after transplantation,which reduces the therapeutic efficiency of MSCs.Statins have a variety of beneficial effects independent of lipid regulation,which can promote the proliferation of MSCs and inhibit the apoptosis of MSCs.This paper reviewed the application and mechanism of MSCs combined with statins in the treatment of DR.

Objective:To investigate the expression and the effects of CD40/CD40L in lung tissue of rabbits with hemorrhagic shock.Methods:18 healthy rabbits were randomly divided into control group(group A),hemorrhagic shock 1 hour group(group B) and hemorrhagic shock 2 hours group(group C),with 6 rabbits in each group.Except the rabbits in the control group,rest rabbits were made into hemorrhagic shock models with lung injury according to Wiggers modified method.TNF-?、IL-10 in plasma were measured by ELISA.Expressions of CD40 and CD40L in lung tissue were measured by immunohistohemistry.Water quantity and pathological change in the lung were observed.Results:The lung of group B and C displayed obvious injury,water quantity increased(P

Objective To evaluate the feasibility of combined application of helicobacter pylori stool antigen(HpSA)-and traditional serology in epidemiologic study of helicobacter pylori(Hp) infection in children. Methods Hp serum IgG antibodies were examined among 480 healthy children. Heticobacter pylori stool antigen(HpSA) were measured among children who were seropositive. Hp status was defined as positive when stool antigen test was positive, Hp status was defined as negative when seronegative. A case - control study was conducted to identify risk factors of Hp infection in preschool children. Results Among 480 preschool children, 172 (35 8 %) were sero- positive, 64(13.3 %) with positive result of HpSA test were diagnosed as current Hp infection. Univariate factor analysis demonstrated that Hp infection clustered in families and Hp infection was often acquired in childhood by oral-oral and fecal - oral person to person transmission. Conclusions HpSA and serology screening are two nomnvasive tests, simple not costly, effective and accurate. The combination of these 2 noninvasive methods can be applied in epidemiologic study of Hp infection in childrenJAppl Clin Pediatr,2004,19(11):948-950

Objective To present our experience with the management of symptomatic ureteral calculi during pregnancy and to compare the effi?cacy of two treatments:double?J stent insertion and ureteroscopy. Methods In a retrospective study between January 2007 and January 2015,38 pregnant women were treated for symptomatic ureteral calculi in our hospital. The patients were divided into two groups based on whether they re?ceived double?J stent insertion(n=21)or ureteroscopic lithotripsy(n=17). We collected and compared the patients 'characteristics and treat?ment outcomes,such as success ratio,rate of complications,surgical time,medical costs,and hospitalization time. Results In the double?J group, the insertion of a double?J stent was possible for 17 of 21 patients(success rate,81.0%). In the ureteroscopy group,15 of 17 patients had complete calculi fragmentation(success rate,88.2%). Complications in the double?J stent retention group were slightly higher than in the ureteroscopic litho?tripsy group. The medical costs and hospitalization time required to perform ureteroscopic lithotripsy were significantly higher compared to double?J stent insertion. Patients in the double?J group contended with stones after delivery. Conclusion Both of double?J stent insertion and ureteroscopic lithotripsy are effective for the treatment of symptomatic ureteral calculi during pregnancy. The success rate of ureteroscopy ,which can directly dis?rupt stones,was higher. However,double?J stent insertion costs less and is simple and convenient. The technique that is chosen to be performed de?pends on the patient's practical situation and personal preference.

Objective To search the status quo of students'thanatopsis in order to push focused education on terminal care to the nursing major students.Metheds To distribute home-made questionnaire to 268 nursing students.Results students who cannot talk about death normally account for 21.3 percent;who never considered death or unnecessary to consider death account for 12.9 percent of the total;who considered a lot account for 10 percent;who cannot handle terminally ill account for 74.3 percent;and who prefer self-suicide when suffered defeat account for 4.9 percent.Conclusion Nursing students have insufficient ideas of death,and they need to think deeply about the meaning of death and to nurture a positive outlook on death in order to get a correct terminal care education.
