Objective: To observe the protective effect of WenyangHuoxueFang on renal interstitial fibrosis in rats and try to explore the mechanism.Methods: The renal obstruction model of rats was established by unilateral ureteral obstruction(UUO) ,and then they were divided into four groups randomly,including UUOW group(treated with WenyangHuoxueFang),UUOF group(treated with Fosinopril),UUO group and the sham-operation group.The morphological changes of kidney tissue were observed,the level of RBP was detected by ELISA,the expression of MMP-3 and TIMP-1 was detected by immuno-histochemistry.Results: Compared with the sham-operation group,there were different degrees of kidney lesions in UUO group and the treatment groups.The level of RBP in UUO group was significantly higher than that in sham-operation group.Compared with UUO group,the RBP expression in UUOF group and UUOW group was significantly lower(P0.05).The expressions of MMP-3 and TIMP-1 in UUO group were increased,and the amplitude of increasing expression of TIMP-1 was higher than that of MMP-3.The treatment groups had higher expression of MMP-3(P

OBJECTIVETo explore treatment effect of the locking plate percutaneous external fixation to tibial fractures.

METHODSFrom July 2010 to February 2013, 8 cases with pediatric tibial fractures were treated by using unilateral locking plate percutaneous external fixation,including 6 males and 2 females with an average age of 7 years old ranging from 4 to 10. Among them, 5 cases were open fractures involving 1 case of Gustilo-Anderson type II, 3 cases of type III A, 1 case of type III B; and the other 3 cases were closed fractures involving 2 cases of AO type A3, 1 cases of type B2. The postoperative bone healing and gait impact were observed and the function was evaluated by Johner-Wruhs scores.

RESULTSAll fractures healed successfully without infection. The fracture healing time was from 3 to 6 months with an average of 3.9 months. The locking plate removal time was from 4 to 7 months with an average of 4.3 months. Among them, 7 cases were visually normal after walking with stand, 1 case of anterior tibial tendon defect affected gait. The results of Johner-Wruhs assessment were excellent in 7 cases, good in 1 case. No rub contralateral medial calf skin wounds occurenced.

CONCLUSIONThe method is simple, stable and reliable. The fixation strength is suitable for children using locking plate percutaneous external fixation. The postoperative functional recovery was excellent and the walking gait was less affected. But the point of LCP pedicle screw should be carefully selected before installation with good skin coverage.

OBJECTIVE To investigate the present situation of the nosocomial infection in our hospital in order to decrease the infection rate. METHODS A total of 40 554 patients were inspected from Oct 2004 to Sept 2005.There were 626 patients with nosocomial infection. RESULTS The nosocomial infection was 1.54%.Old patients were the main components.The longer they were in hosptial,the more risk of infection they had.Elder monitoring department and hematological department were the most common infected units.Respiratory tract was the most common infected site of the body.The entity of disease for the most infection was malignant tumor.Invasive treatment was one of the causes for the infection. CONCLUSIONS The infection rate of our hospital was relatively low.We should establish the system to control the infection.Use the advanced statistical software well be to aid the control and discover the anti-infection deficiency from the statistical view-point.

OBJECTIVE To summarize the infection cases and the factors causing site infection after operations,and investigate the measures to prevent and reduce exogenous incision infection.METHODS Discharged patients from Jan 1st,2003 to May 31st,2006 in our hospital were investigated for retrospective analysis on incision infection cases.RESULTS Totally 111 incision infection cases were reported from 54 286 cases.The nosocomial infection rate in this cohort was 0.21%(111/54 286),which was 33.44% of total surgical incision infection cases.CONCLUSIONS Incision infection is one of the most commonly encountered concomitant symptoms,it is as well the bottleneck for our hospital to reduce average stay length of surgical patients and patients′ hospitalization expenses,and to speed up turnover of beds.Incision infection rate is also an important criterion to evaluate the management quality and medical technology quality within and among hospitals.Effective measures should be taken to decrease incision infection rate and to resolve the problem that is difficult to hospitalize and expensive to treat.

Objective To calculate workload according to working day and holiday separately.Methods Functions of SQL in Oracle were used to separate working day and holiday.Results The method could accomplish holiday's workload statistics expediently.Conclusions Statistics of holiday's workload are becoming ordinary work,so the separated analysis for them has practical value.

Objective To investigate the association between mycoplasma infection and pathogenesis of renal cell carcinoma(RCC). Methods There were 95 samples of archived embedded tissues of RCC and 60 samples of archived embedded normal renal tissues around the tumor for comparison.We detected mycoplasma hyorhinis P40 expression in archived embedded renal tissues by immunohistochemistry(IHC) with mycoplasma hyorhinis monoclonal antibody(MAb) PD4. Results Mycoplasma hyorhinis P40 was present in 64.2%(61/95 cases) of RCC and in 21.7%(13/60 cases) of the paratumor normal renal tissues in controls.The mycoplasma hyorhinis P40 expression ratio in RCC was significantly higher than that in the normal renal tissue,around the tumor(P

Objective To investigate the association between mycoplasma DNA and renal cell carcinoma (RCC). Methods There were 95 samples of archived embedded tissues of RCC. We detected mycoplasma DNA in the tissues by nested polymerase chain reaction (PCR) with mycoplasma universal primer. Results The mycoplasma DNA detection ratio in RCC samples was 81.1%. The samples with moderate and low differentiation had a higher mycoplasma DNA ratio (90.9%) compared with that of high differentiation samples (72.6%) (P

Objective To investigate the development and dynamic changes of host immune response in DBA/2 mice infected with Plasmodium yoelii 17XL. Methods Female DBA/2 mice were infected by intraperitoneal ( i. p. ) injection of 106 P. yoelii 17XL parasitized erythrocytes ( PRBC). Levels of IL-12, IFN-γ, IL-4, IL-10 and P. yoelii 17XL-specific antibody in sera were measured by ELISA. Concentrations of NO in cell supernatants were measured by the Griess reaction. Parasitemia,percentage of mononuclear-macrophages of individual mice were monitored daily, and phagocytosis of mononuclear macrophages was also observed. Results Primary parasitemia in vein blood was developed on day 3 postinfection, which peaked with a level of 46. 9% on day 9. Most mice cleared the infection and survived by day 20 postinfection. From day 6 to day 16, the phagocytosis of PRBC by rodent macrophages was observed on the blood smear. Infected mice had a continuously increased level of IL-12 in serum from day 1 postinfection. Accordingly, high level of IFN-γ was also detected in sera from day 1 postinfection,which peaked on day 6. Infected mice produced higher level of IL-4 and IL-10 in serum on day 6 postinfection, which peaked on day 9 and day 15 postinfection respectively. In addition, splenocytes from infected mice produced significantly higher level of NO on day 6 and 20 postinfection. Level of P. yoelii 17XL-specific IgG was determined in the sera of infected mice with a steadily increased trend after infection, which peaked on day 70 postinfection. Conclusions Effective polarizing of Thl cells is significant in inhibition of parasitemia and eventual clearance of the Plasmodium parasites. Activated mononuclear-macrophages play a key role in inhibiting parasitemia in the early phase of infection with P. yoelii 17XL.

Objective To discuss the clinical characteristics of diagnosis and treatment of primary gastric malignant lymphoma (PGML). Method The data from 34 PGML medical records were reviewed retrospectively between January 2001 and May 2008. Results There were 23 cases of B-cell malignant lymphoma, 7 cases of T-cell malignant lymphoma, and 4 cases of non-B and non-T small cell lymphoma. Confirmed by pathology, 14 cases of them had metastasis to lymphoid nodes and 5 cases had invaded the organs nearby. All of these 34 cases had gastroendoscopy before operation. Conclusions PGML has no specific manifestation, and the definitely diagnostic rate of gastroendoscopy is low. The surgical resection is the major therapy.Operative pattern,the size of tumor,pathological stage can predicate the prognosis for PGML.
