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

Objective To investigate the clinical value of the variety of serum levels of soL-CXCL16 and NT-proBNP peripercutaneous coronary intervention(PCI) in patients with acute myocardial infarction (AMI).Methods A total of 77 cases received PCI were selected to research group.And the contemporaneous 30 healthy persons were chosen to control group.The serum levels of soL-CXCL16,NT-proBNP and cTnT were detected by ELISA.The relationships of soL-CXCL16 and NT-proBNP to cTnT were detected by Pearson linear correlation analysis.Results Compared to pre-PCI,the serum levels of CXCL16 were rising to the peak point at 0.5 h post-PCI,and were decreasing from 2.0 h post-PCI,then the serum levels of CXCL16 were declining to the levels of pre-PCI at 24.0 h post-PCI (P＜0.05).And the serum levels of NT-proBNP were rising from 0.5 h post-PCI,and the peak point was at 24.0 h post-PCI (P＜0.05).The postive relationships of the serum levels of CXCL16 and NT-proBNP to the serum levels of cTnT were confirmed by Pearson linear correlation analysis(P＜0.01).Conclusion Monitoring of soL-CXCL16 and NT-proBNP for patients with percutaneous coronary stenting could provide foundation for prognosis evaluation of PCI.

Objective To evaluate the effect of the combination of lamivudine and adefovir dipivoxil on the treatment of decompensated hepatitis B cirrhosis patients. Methods One hundred thirty-six patients with decompensated hepatitis B cirrhosis were randomly administered the combination of lamivudine and adefovir dipivoxil (combination group), only lamivudine( LAM group)and only adefovir dipivoxil (ADV group). The liver founction tests, ChildPugh scores and the rate of negative conversion for the serum HBV-DNA were measured at baseline,six months after therapy and 12 months after therapy. Results The rate of negative conversion for the serum HBV-DNA ( ＜ 1 ×103cop/ml)of combination group were 78.3% and 85.2% respectively at six and twelve months after therapy. The rates of negative conversion for the serum HBV-DNA of LAM group were 62. 1% and 57.8% respectively at six and twelve months after therapy. The rates of negative conversion for the serum HBV-DNA of ADV group were 41.3% and 53.6% respectively at six and twelve months after therapy. Compared with the LAM and ADV group, The rates of negative conversion for the serum HBV-DNA of combination group were higher. In addition, the rates of better conversion of liver function tests and Child-Pugh scores were higher in combination group than LAM and ADV groups.Conclusion The combination of lamivudine and adefovir dipivoxil could more effectively improve liver founction tests, Child-Pugh scores and the rates of negative conversion for the serum HBV-DNA in patients with decompensated hepatitis B cirrhosis than only lamivudine and only adefovir dipivoxil.

Objective To realise the clinical features and to reduce the diagnostic errors of hepatolenticular degeneration patients with liver injure. Methods Clinical manifestations, results of las tests and admitting diagnosis of 23 hepatolenticular degeneration cases were reviewed. Results All cases showed the elevation of serum transami-nase and/or total bilirubin. 17 cases(73.9% ) had manifestation of liver malfunction while nervous system symptoms were merely found in 2 cases. The decreased ceruloplasmin and elevated 24 hour urinary cuprum were detected in 23 and 21 cases respectively. Positive K-F rings were observed in 17 of 23 patients. Misdiagnosis rate of admitting diagno-sis exceeded 43.5%. 2 cases died after treating with penicillamine. Conclusion Liver injure that is one of the com-mon clinical features results in the diagnostic errors, but the combination detection will improve the accuracy of hepa-tolenticular degeneration.

Objective To discuss the clinical manifestation and treatment of the complications caused by injected polyacrylamde hydro-gel( PAAG) for breast augmentation. Methods This retrospective research was performed among 212 patients who undergoing breast aug-mentation with injected polyacrylamde hydrogel. The clinical manifestation and treatment outcome of the complications were analyzed and summarized,which is aim to search an effective treatment method. Results For the 212 patients,the main complications were breast multi-ple indurations (131 cases),fever (9 cases),infection (14 cases),breast pain (65 cases),PAAG displacement (28 cases) and secondary deformity or asymmetry (25 cases). 152 cases experienced one clinical symptom,the rest patients simultaneously undergone no less than two clinical symptoms. Patients were received open operation with periareolar incision ( surgery group) or vacuum absorption by needle ( aspira-tion group) for dislodging PAAG. No significant difference was found in wound healing,breast shape satisfaction and pain anesis between the two groups. Whilethe surgery group was better than the aspiration group in efficiency for taking out PAAG and the incidence of reoperation, with statistical significance. Conclusion A plenty of complications occurred after breast augmentation with injected polyacrylamde hydrogel, the method of open operation with periareolar incision is a better way for eliminating PAAG and treating the complications.

Objective To investigate the clinical utility of anti-dsDNA antibody in the diagnosis of systemic lupus erythematosus (SLE).Methods Total and high affinity anti-dsDNA antibodies of 431 serum samples were measured by total and high affinity anti-dsDNA antibody EIA kits.Modified SLE disease activity index (M-SLEDAI) was scored for each SLE patients at the time of serum collection.The agreements between total and high affinity anti-dsDNA EIA tests and the correlation of anti-dsDNA antibody levels with disease activity and clinical manifestations were analyzed.Statistical analysis was performed using x2 test,Spearman correlation,Mann Whitney U test & Fisher exact,Student t test.Results ① The overall agreement between total and high affinity anti-dsDNA antibodies was 93.3％,and the total agreement of SLE patients was 89.6％.Twenty-two out of 23 (95.7％) SLE patients with positive total anti-dsDNA antibody but high affinity antidsDNA antibody were inactive with the M-SLEDAI score less than 4.Four patients with other autoimmune diseases had positive total anti-dsDNA antibody but negative on high affinity anti-dsDNA antibodies.② The total and high affinity anti-dsDNA antibody levels were significantly positively correlated with disease activity (M-SLEDAI) and negatively correlated with serum C3 and C4 levels (P＜0.01).③ The ratio of high affinity to total anti-dsDNA antibody was significantly higher in patients with M-SLEDAI ≥4 or with active kidney damage (P＜0.01).Conclusion Both total and high affinity anti-dsDNA antibodies are significantly correlated with SLE disease activity and kidney damage.However,the high affinity anti-dsDNA antibody may be more specific for active SLE and helpful in the differential diagnosis with other autoimmune diseases.High affinity anti-dsDNA antibody is more valuable in monitoring SLE disease activity status,especially on kidney damage,compared to total anti-dsDNA antibodies.

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 incidence and the risk factors of anxiety or depression and in the first degree relatives (FDRs) of patients with type 2 diabetes mellitus ( T2DM ). Methods A total of 102 T2DM patients who visited our hospital from May to July 2010 and their FDRs completed SAS,SDS,and life satisfaction evaluation. The medical history of T2DM patients was collected and compared with their FDRs with or without mental disorders. The correlations of risk factors with anxiety or depression were analyzed, t test or X2 test were used for statistical analysis and a P value less than 0. 05 was considered statistically significant. Results The incidence of anxiety or depression of FDRs was 31.4% and 17.6%,respectively. The life satisfaction score of FDRs with mental disorders was significantly decreased ( t = 4. 26 and 4. 09, P＜0. 05 ). Fasting glucose level of T2DM patients with anxious or depressive FDRs was significantly increased ( t = -2. 48 and -2. 15, P＜0. 05 ). Higher medical cost and multiple treatment strategies were positively correlated with SAS and SDS score of the FDRs. Conclusion Higher incidence of mental disorders and lower satisfaction scores could be found in the FDRs of T2DM patients. Better control of blood glucose and reduced treatment cost and strategies may be useful in improving metal condition and life satisfaction of the FDRs of T2DM patients.
