OBJECTIVE To study the pharmacokinetic and distribution of arctiin in rats. METHODS Each rat was given a single dose at random by oral administration. The arctiin in serum and organs were determined by use of RP-HPLC. All pharmacokinetic parameters were calculated with a 3P87 program. RESULTS After oral administration of arctiin at the dose of 300mg·kg-1, Arctiin plasma C-T curve conform to open two-compartment model. The Pharmacokinetic parameters were as follow: A=(37.374 5±8.964 7)μg·mL-1;B=(6.210 6±1.489 3)μg·mL-1;α=(0.004 3±0.000 9)min-1;β=(0.000 4±0.000 2)min-1;Kα=(0.420 2±0.167 5)min -1;t1/2α=(115.192 6±14.382 4)min ;t1/2β=(1 485.578 1±161.173 3)min;K10 =(0.001 0±0.000 4)min -1;K21=(0.001 4±0.000 6)min -1 ;K12=(0.002 3±0.001 3)min -1 ;Cmax=(41.786 3±7.521 7)μg·mL-1 ;Tmax=(9.891 9±4.341 4)min;AUC=(22 503.272 7±4 120.182 8)μg·min·mL-1. Liver had the highest concentration of arctiin after oral administration. CONCLUSION RP-HPLC method is rapid, sensitive and specific for the research of arctiin pharmacokinetic and its distribution in rats. Arctiin is distributed and eliminated quickly in rats.

OBJECTIVETo study changes of left ventricular remodeling (LVR) in hypertension patients with carotid atherosclerosis (CAS) of phlegm-dampness syndrome (PDS).

METHODSDoppler ultrasonography data of CAS were observed in 223 hypertension patients with CAS (as the hypertension group, including 119 patients of the PDS group and 104 of the non-PDS group), 81 CAS patients with non-hypertension, and 19 non-hypertension non-CAS patients (as the control group). The difference in the degree of LVR was compared among the above groups.

RESULTSThe left ventricular posterior wall thickness (LVPWT), inter ventricular septum thickness (IVS), E/A were higher in the hypertension group than in the non-hypertension group (P < 0.05). The left ventricular end-diastolic dimension (LVEDD), left ventricular end-systolic diameter (LVESD), stroke volume (SV) were higher in the soft plaque hypertension group and the soft plaque non-hypertension group than in the hard plaque group, the thickening intimal group, and the normal intimal group (P < 0.01 , P < 0.05). The LVEDD, LVESD, and SV were higher, and the ejection fraction (EF) was lower in the PDS hypertension group than in the non-PDS hypertension group (all P < 0.05). Of them, LVEDD, LVESD, and SV were higher in the soft plaque group than in the hard plaque group (P < 0.01), the thickening intimal group (P < 0.01) and the normal intimal group (P < 0.05). There was no statistical difference in PDS hypertension between the soft plaque group and the hard plaque group (P > 0.05).

CONCLUSIONThe hypertension patients with CAS of PDS might be correlated to LVR, and LVR was more obviously in the soft plaque patients.

Objective To evaluate the application and the good qualities of high-resolution ultrasound and CDFI-guided mammotome minimally invasive biopsy device in the diagnosis and treatment of breast lesions.Methods The common clinical operations and the lesions which were guided mammotome minimally invasive biopsy device by high-resolution ultrasound and CDFI were contrasted.The effects of treatment were evaluated.Results 307 le- sions of 102 patients were removed by this method,and the operational process was successful.Patients' skin lacera- tions were tiny.Only one lesion was clinically diagnosed as mild blood clot under skin,but without other complica- tions.Conclusion Contrasted with the common clinily operations.the high-resolution ultrasound and CDFI-guided mammotome minimally invasive biopsy device in the diagnosis and treatment of breast lesion is effective,and the scar is tiny.It releases patients' pain.

Objective To evaluate the quality of the portal images acquired by computed radiography(CR)system and conventional screen-film system,respectively.Methods imaging plates (IP)and X-ray films of a home-devised lead phantom with a leakage of 6.45% were acquired,and modulation transfer function(MTF)curves of the both images were measured using edge method.Portal images of 40 nasopharyngeal cancer patients were acquired by IP and screen-film system respectively.Two doctors with similar experience evaluated the damage degree of petrosa] bone,the receiver operating characteristic(ROC)curve of CR images and general images were drawn according to two doctors evaluation results.Results The identification frequency of CR system and screen-film system were 1.159 and 0.806 Lp/mm respectively.For doctor one,the area under ROC curve of CR images and general images were 0.802 and 0.742 respectively.For doctor two,the area under ROC curve of CR images and general images were 0.751 and 0.600 respectively.The MTF curve and ROC curve of CR are both better than those of screen-film system.Conclusion The image quality of CR portal imaging is much better than that of screen-film system.The utility of CR in linear accelerator for portal imaging is promising in clinic.

Objective To describe the prevalence of metabolic syndrome(MS) among rural adult residents in Ningxia, under IDF2005 ATP Ⅲ 2005 AHA and CDs2004 definition. Methods Stratified cluster sampling methods was used and the participants were interviewed by trained health workers under a structured questionnaire. The number of research subjects was 1612. Fasting plasma glucose (FPG), blood lipids, body mass index (BMI) and blood pressure (BP) of all samples (1612 subjects) were measured, and related data was analysed by IDF2005, ATP Ⅲ 2005 AHA, as well as CDs2004 definition of MS. Results The age-standardized prevalence of MS was 15.00% by ATP Ⅲ 2005 AHA definition and 11.80%by IDF 2005 definition and 6.71% by CDs 2004 definition, respectively. Based on IDF 2005 and ATP Ⅲ 2005 AHA definition, women had higher prevalence than men (16.3% vs. 5.4%, 18.9% vs. 8.9%, P<0.01), but there was no significant difference (P>0.05) between them according to the CDs definition. MS prevalence among Hui (Muslim) ethnic group was higher than Han ethnic group(P<0.05). The prevalence of MS increased with age in all samples and the prevalence of MS started at age of 35 in Hui ethnic group, higher than in Han ethnic group. There was no significant difference in the prevalence rates of MS between male Hui ethnic group and male Han ethnic group (P>0.05). The prevalence of MS in female Hui ethnic group was higher than Han ethnic group females (P<0.05). Conclusion The prevalence of MS was high in the rural adult residents, in Ningxia. Clusters of MS components were commonly seen, and the main disorder appeared in lipid abnormalities and abnormal glucose metabolism. It is necessary to discuss that the cut off point of central obesity for the waist circumference diagnostic criteria of MS in different ethnic groups in China. Big differences on the components of MS were seen in different ethnic groups. It is important to choose suitable MS definition for prevention of MS and to reduce the incidence of cardiovascular disease.
