Objective To establish the quality standard for Kangganmao Granule.Methods Radix scutellariae,radix et rhizome glycyrrhizae and radix platycodonis in the prescription were identified by TLC.The content of the baicalin was determined by HPLC.The column of AichromBond-AQ-C18(4.6 mm? 150 mm,5 ?m)was used.The mobile phase was CH3OH-H2O-H3PO4(43:57:0.2),with the flow of 1.0 mL/min,the column temperature of 30 ℃,and peaks were detected at 280 nm.Results The characteristic of identification by TLC was distinct and highly specific.The linear range of baicalin was 0.049 6～0.297 6 ?g,r =0.999 7,the average recovery was 101.80%,RSD=1.86%(n=6).Conclusion The method was easy to operate with accurate result and good reproducibility.It can be used effectively for the quality control of the preparation.

Objective To assess whether echocardiographic parameters of M-mode,pulsed-wave Doppler and tissue Doppler imaging which were usually used for selecting cardiac resynchronization therapy (CRT) candidates could predict CRT responders.Methods Twenty-nine patients with NYHA class Ⅲ or Ⅳ heart failure,left ventricular ejection fraction(LVEF)≤35%,QRS≥130 ms were enrolled.All of them underwent biventricular pacemaker implantation.The septal-to-posterior wall motion delay(SPWMD) from M-mode recording,and the standard deviation of time to peak systolic velocity(Ts-SD) were used to evaluate intraventricular dyssynchrony.The interventricular mechanical delay (IVMD) by pulsed Doppler echocardiography was calculated by subtracting the right ventricular preejection intervals (RV-PEI:the onset of the QRS on the electrocardiogram to the onset of pulmonary outflow) from the left ventricular preejection intervals (LV-PEI:the onset of the QRS on the electrocardiogram to the onset of aortic outflow).At least 15 % reduction in left ventricular end-systolic volume(LVESV) at the 6-month after CRT was defined as responder.Results In the 29 patients,there were 20 (68.97%) responders.The area under the receiver operating curve(ROC) of SPWMD,Ts-SD,LV-PEI,RV-PEI and IVMD to predict CRT responders was 0.448 (95% CI 0.184-0.712,P＞0.05),0.557 (95% CI 0.317-0.798,P＞0.05),0.479 (95% CI 0.186-0.773,P＞0.05),0.568 (95 % CI 0.272-0.863,P＞0.05) and 0.411 (95% CI0.136-0.687,P＞0.05),respectively.Conclusions M-mode echocardiography,pulsed Doppler and tissue Doppler imaging failed to predict CRT responders.New echocardiographic techniques including threedimensional echocardiography and speckle tracking image will be investigated,and may improve the predictive power.

Objective To evaluate left ventricular torsion in patients after coronary artery bypass graft(CABG) surgery by velocity vector imaging(VVI). Methods Twelve patients who were scheduled to have CABG surgery were enrolled. VVI offline software was used to evaluate myocardial rotation in both basal and apical segment before and three months after CABG. The rotation and rotation rate of each a counterclockwise rotation at the apex and a clockwise rotation at the base, and the absolute value of CABG the rotation at the base was significantly improved than that before CABG (P <0.001), and the rotation in the segment of anterior septum, anterior wail and inferior septum at the base was higher than that rotation in the apical and basal segment three months after CABG was also significantly higher than that negative peak rotation rate in the early diastolic period at the apex were significantly higher than those at the improved than that before CABG (P <0.001). And the positive peak rotation of the systolic period in the segment of anterior septum,anterior wall,lateral wall and inferior septum and the negative peak rotation of the diastolic period in the segment of anterior and inferior septum at the base were also higher than those before CABG (P <0.001). Conclusions VVI is a useful method which can quantitatively assess left ventrieular torsion in patients before and after CABG surgery.

Objective:To compare the DNA character with in cholesteatoma tissues with that in normal skin.Method:DNA content within 25 cholesteatoma tissues and 10 normal postauricular skin was measured with flow cytometry.Result:The content of cholesteatoma tissues and postauricular skin specimens are a normal euploid.The cell number during S phase of cholesteatoma(10.9±2.32)% was higher than that in normal skin(7.31±2.82)%.Conclusion:Although the cholesteatoma has a very high proliferating character,the result suggest it isn′t a malignant tumor.

The expression of proliferating cell nuclear antigen (PCNA) and B-cell lymphoma/leukemia-2 gene (Bcl-2) was detected in 25 cases of cholesteatoma tissues and 10 cases of normal skin by using immunohistochemical technique. The results showed that the PCNA index of cholesteatoma tissues was higher than that of normal skin, but Bcl-2 was not expressed in cholesteatoma tissues and normal skin. The PCNA index was correlated with the aggressiveness of cholesteatoma. It was suggested that PCNA could be considered to be a prognostic marker and an indicator of aggressive behavior in cholesteatoma. Although the cholesteatoma had a very high proliferating character, it wasn't a malignant tumor.

Objective To compare the safety and recent efficacy between transcatheter and surgical closure of secondum atrial septal defect over 50 years of age. Methods Retrospective analysis was done on 66 patients over 50 years of age who underwent transcatheter (30 cases) and surgical (36 cases) closure of secondum atrial septal defect.The median age was 60.8?7.1 years old in the transcatheter closure group and (57.5?6.3) years old in the surgical closure group( P=0.04).The median sizes of atrial septal defect in the transcatheter and the surgical closure group were 24.9?7.2 mm and 30.4?11.0 mm respectively (P=0.02). We compared the recent efficacy、 complications and prognosis between two groups. Results The instant procedural success rate was 93.3% for the transcatheter closure group and 100% for the surgical group (P=0.85). 2 procedures in the transcatheter closure group failed, 1 patient (2.6%) in the surgical group died during hospitalization and 9 patients (25.0%) underwent Devage tricuspid annuloplasty. Newly onset atrial arrhythmias occurred in 3.3% in the transcatheter closure group and 22.2% in the surgical closure group (P=0.03). After the procedures, right atrial and ventricular dimensions were decreased from 38.0?9.0 mm to 35.2?10.1 mm and from 44.2?8.6 mm to 36.2?9.0 mm in the transcatheter closure group whereas in the surgial group, the atrial and ventricular sizes fell from 44.1?8.2 mm to 38.2?9.5 mm and 49.0?10.2 mm to 37.1?11.0 mm respectively (P

Objective: To develop a quantitative PCR method for detecting hookworm infection and quantification. Methods:A real-time PCR method was designed based on the intergenic region II of ribosomal DNA of the hookworm Necator americanus. The detection limit of this method was compared with the microscopy-based Kato-Katz method. The real-time PCR method was used to conduct an epidemiological survey of hookworm infection in southern Fujian Province of China. Results:The real-time PCR method was specific for detecting Necator americanus infection, and was more sensitive than conventional PCR or microscopy-based method. A preliminary survey for hookworm infection in villages of Fujian Province confirmed the high prevalence of hookworm infections in the resident populations. In addition, the infection rate in women was significantly higher than that of in men. Conclusions: A real-time PCR method is designed, which has increased detection sensitivity for more accurate epidemiological studies of hookworm infections, especially when intensity of the infection needs to be considered.

Objective: To study the acute and long-term toxicity of brucea javanica oil subnanoemulsion injections ( BJOSI ) . Methods:The mice were given BJOSI by intravenous injection. The acute toxicity was observed and LD50 in mice was calculated by Bliss method. To observe the long-term toxicological effects, Beagle dogs were injected intravenously BJOSI once a day for 8-week du-ration with the dose of 20, 10 and 6 ml·kg-1 , respectively followed by 3-week recovery period. Results:LD50 of BJOSI in mice was 7. 388 g·kg-1 with 95% confidence limits of 6. 306-8. 656 g·kg-1 . The long term toxicity test showed that all the detected indices were within normal range in all groups, including general state, weight changes,hematological indices,biochemical indices,EEG,organ coefficients, morphological and histological changes, while there was an upward tendency of ALT and Cr in every BJOSI group without dose-effect correlation. The dogs could completely recover in three weeks after the administration. Conclusion:The results suggest that BJOSI has low toxicity,while the pathological changes are reversible, and attention should be paid to the function of liver and kidney.
