Objective:To investigate the consistency of two methods in the measurement of bone mineral density in the lateral lumbar vertebra.Methods:The bone mineral densities of the 2nd,3rd and 4th lumbar vertebras in 18 female patients,at a preset side lying position,were measured respectively by two methods(lateral spine analysis,LS and lateral vertebral analysis,LVA) provided by the dual-energy(X-ray) absorptiometry(GE Lunar,Prodigy).The results were recorded and analyzed by SPSS(Version(10.0).) The values of bone mineral density were displayed by boxplot,paired and analyzed by(Wilcoxon's) signed rank test and(Pearson's) correlation analysis.Statistical significance was considered when P(0.05),) and were clearly correlated(P

Objective To establish the method for detemining the content of ephedrine hydrochloride in Zhike Pingchuan Tangjiang by HPLC. Methods Diamonsil ODS1 C_(18) Column was used with acetonitrile -0.1% phosphoric solution (with 0.1% triehylamine) (3 : 97) as the mobile phase, the detection wavelength as 205 nm, and flow rate was 1.0 mL/min. Results The calibration curve was linear at the range of 0.12～ 0.96 ?g for ephedrine hydrochloride and linear equation was Y= 109759X+3792.8, r=0.9998. The average recovery was 98.4% and RSD was 0.87% (n =5). Conclusion This method was simple, accurate and proper, with good reproducibility. It can be used for quantitative analysis of ephedrine hydrochloride in Zhike Pingchuan Tangjiang.

Objective: Recent studies have suggested that congestive heart failure(CHF) is related to neuroendocrine system and cytokines,and its activation contributes to myocardial remodeling and leads to the development and progression of CHF.Tumour necrosis factor-?(TNF-?) is one of the most important factors.This study intends to establish the animal model of isoproterenol(ISO)-induced CHF in rats and to study the changes of serum TNF-?.Methods:Male SD rats were randomly allocated to the ISO-induced CHF group(n=50) receiving two subcutaneous injections of 170mg ISO per kilogram of body and the healthy control group(n=10) receiving two subcutaneous injections of 0.25ml normal saline.At 18th week,the hemodynamic parameters including HR,LVSP,LVEDP and ?dp/dtmax were assessed.TNF-? in plasma were all detected.Results:Compared with the control group,the LVSP、?dp/dtmax significantly decreased and the HR,LVEDP enlarged notably in CHF group(P

Objective To explore the efficacy of intraductal chilled saline perfusion (ICSP) to reduce the thermal bile duct injury during the treatment of radiofrequency ablation (RFA) associating with occlusion of hepatic blood supply in rabbits.Methods 16 healthy New Zealand white rabbits were divided into 2 groups.Rabbits of the ICSP group were placed tubes in the common bile duct after laparotomy,and ICSP was performed during the RFA procedure accompanied with hepatic blood occlusion.While for rabbits of the non-ICSP group,hepatic blood occlusion and RFA were performed without ICSP.RFA electrodes were placed about 5 mm away from the hilus hepatis approximately.Contrast-enhanced ultrasonography (CEUS) was administrated to evaluate the sizes of the ablative zones after the procedure.On post-procedure 6 week,ultrasonography was prerformed to evaluate the changes of the biliary structure,and liver specimens of rabbits wcrc obtained for histopathologic observation of main bile ducts.Results Post-procedure CEUS examination showed that there was no significant difference in the size of the ablative zone between the groups (P ＞0.05).On post-procedure 6 week,rabbits of the ICSP group appeared with biliary dilatation more frequently by ultrasonography (P ＜0.05),and a higher degree of the injury of main bile duct by histopathologic observation (P ＜0.05).Conclusions In treatment of RFA accompanied with hepatic blood occlusion,RFA-induced bile duct injury may be decreased significantly with ICSP.

ObjectiveTostudytheinhibitioneffectof c-mycASODN(antisense oligodeoxynucleotide) and 5-FU (5-fluorouracil) on the expression of c-myc gene and the proliferation of human hepatomacellsHEPG-2. MethodsAfter treatedbyliposomemediatedc-mycantisense phosphorothioate oligodeoxynucleotide (APSODN) and 5-FU, the growth inhibition rate was detected by MTT assay, the expression of c-myc mRNA was detected by RT-PCR and immunohistocehemical methods HEPG-2cells. The cell cycle was analyzed by flow cytometric analysis. The morphological changes were observed by fluorescence staining and cellular genome electrophoresis. ResultsAfter sealing c-myc gene with ASODN,the growth of cells was repressed and the effect was time-dependent and dose-dependent ( P = 0. 02 ). The ability of proliferation decreased, the expression of c-myc gene was inhibited on transcription and translation levels; 5-FU can induce apoptosis of hepatoma cells HEPG-2 dramatically with the dose of 10 μ mol/L, when treated by both c-myc ASODN and 5-FU, HEPG-2 cells was induced apoptosis in a cooperative style ( P =0. 01 ).ConclusionsThe liposome mediated c-myc (APSODN) and 5-FU can inhibit the proliferation of HEPG-2 cells by inhibiting the expression of c-myc gene and can induce apoptosis of hepatoma cells HEPG-2 in a cooperative style. c-myc ( APSODN ) can increase the sensitivity of 5-FU to hepatoma cells and decrease the effective concentration of 5-FU.

Objective To evaluate the feasibility,safety,and efficacy of endovascular repair combined with second-stage surgical debridement for ruptured femoral pseudoaneurysms (RFP).Methods All patients who underwent emergency repair of an RFP in our institution between 2009 and 2013 were identified.Case notes were retrieved for clinical data.Results Seven patients were identified.All the patients were treated with emergent percutaneous stent-graft implantation and secondary surgical debridement.The procedure time was (55 ± 6.32) min,blood loss was (93.33 ± 25.03) ml,hospital stay was (9.5 ± 0.84) d,and no postoperative complications occurred.Conclusions stent graft implantation for the treatment of RFPs is safe and effective in short-or middle-term outcome.It is an alternative for RFPs and may be the better option,which makes the secondary surgical debridement feasible and viable.

Objective:To investigate the influential factors correlated to bone mineral density(BMD) in the lumbar vertebra of postmenopausal females,and to find out the influence of body mass and menostasis time on BMD. Methods: BMD in the frontal and lateral lumbar vertebrae of postmenopausal females were measured by dual-energy X-ray absorptiometry(DXA).The correlations of BMD to age,body height,body mass,body mass index(BMI),menopausal age,and/or menopausal years were analyzed using multiple linear regression with SPSS10.0. Results:The change of BMD in the frontal lumbar vertebra was positive to body mass but negatively with postmenopausal years,and that in the lateral lumbar vertebra was closely correlated to BMI. Conclusion: Bone mineral density decreases with increase of menostasis time.Females with a high body mass numerical value have higher bone mineral density.

Objective: To explore the potential influencing factors of the quality guidelines for medical treatment by factor analysis.Method: We analyzed with the SPSS package 9 quality guidelines for medical treatment in the department of integrated TCM and Western medicine of a hospital,including the out-patient person-time,the number of discharges,the average days of hospitalization,the rate of bed utilization,the frequency of bed rotation,the rate of cure and improvement,the case fatality rate,the coincidence rate of diagnoses at admission and discharge,and the success rate of emergency treatment.Results: Four common factors were extracted,namely,the quantifiable factor,determined by the out-patient person-time,the number of discharges,the average days of hospitalization and the frequency of bed rotation;the treatment factor,determined by the cure and improvement rate and case fatality rate;the diagnostic factor,determined mainly by the rate of bed utilization and the coincidence rate of diagnoses at admission and discharge;and the emergency treatment factor,determined by the success rate of emergency treatment.The cumulative contribution rate of the 4 factors was 85.1%.Conclusion: The amount of medical work,the techniques of treatment,the ability of diagnosis and the efficiency of emergency rescue are the main influencing factors of quality guidelines for medical treatment.
