OBJECTIVE:To investigate the study of traditional Chinese medicine (TCM) in the treatment of chloasma,and to provide reference for clinical treatment and study of chloasma. METHODS:Retrieved from CBM,Wanfang database,CNKI and VIP,usingchloasmaas subject,the literatures of TCM therapy were collected during Jan. 2003-Dec. 2012. Bibliometric meth-od was adopted to analyze included literatures statistically in respects of publication amount,periodicals,research institution,litera-ture types,citing references,other periodicals citatien times,fund support,distribution of provinces and cities. RESULTS:During 2005-2012,the amount of the literatures increased slowly. Among top 10 journals in the list of publication amount,only Chinese Journal of Aesthetic Medicine was not TCM journal and took up the first place. Among top 7 research institutions in the list of publi-cation amount,TCM colleges took up predominant place,followed by TCM hospitals. The types of the literatures were mainly case report,contrastive study before and after treatment,group-divided control study;the amount of group-divided control studies increased gradually year by year. The references cited were mainly English literatures. There were 82 literatures which were cited by other periodicals more than 10 times;the highest time of other periodical citation per literature was 47 times;only 11 literatures were supported by fund. The institutions of literatures authors were distributed in 32 provinces,cities and autonomous regions of China,mainly in the eastern coastal areas. CONCLUSIONS:More and more attention has being paid to TCM therapy for chloas-ma,but the scope and depth of the studies were inadequate. From the point of view of modern medicine,we can explore the patho-logical TCM mechanism and the treatment method of shortening the course of disease.

ObjectiveTo evaluate the accuracy of measurement of left ventricular(LV) volume and function in coronary heart disease(CHD) by real-time three-dimensional echocardiography(RT-3DE) using cardiac magnetic resonance imaging (CMRI).Methods LV end diastolic volume(EDV),LV end systolic volume(ESV) and LV ejection fraction(EF) were measured with RT-3DE in patients with CHD ( n =37) and in the control ( n =30).The results measured by RT 3DE were compared with those of CMRI.The diagnostic value of RT-3DE was evaluated using receiver operating characteristic(ROC) curve.Results Compared with that measured by CMRI,EDV,ESV and EF by RT 3DE( P ＞0.05) were almost similar as that in the control.Area under ROC curve of in EDV and ESV were 0.912 and 0.944 in the control.However,EDV determined by RT-3DE was smaller than that by CMRI( P ＜0.05) in CHD group.A difference (10.95 ± 31.26 ml) was existed in EDV between the two methods.ESV measured by RT-3DE was smaller than that calculated by CMRI( P ＞0.05) with a mean differance of (3.17 ± 16.42)ml in CHD group.EF by RT-3DE( P ＞0.05)was almost as same as that by CMRI in CHD group,with a mean difference of (1.54 ± 11.85)％.The area under ROC curve of EDV and ESV were 0.834 and 0.873 in CHD group and their diagnostic performance was moderate.ConclusionsMeasurment of LV volume and function by RT 3DE in control was more acurrate than that in CHD.In the cases of LV remodeling in patients with CHD,RT-3DE would underestimate the LV volume.

OBJECTIVE: To establish a hepatocyte immunotoxicity model for screening of liver protective medications. METHODS: Cytotoxicity was induced by coincubating BCG-pretreated rat hepatocytes in vivo and with 10 mg/L LPS in vitro. Biphenyldimethylesterate (DDB), malotilate(MLT), silybin(SB) and glycyrrhizin (GRZ) were coincubated along with LPS to prevent the hepatocyte injury and verify the applicability and reliability of the model. AST, LDH and nitric oxide (NO) were measured in both the serum and supernatant. The liver and spleen index were calculated and the liver histopathologic changes were examined microscopically. RESULTS: Supernatant AST, LDH and NO in the BCG combined LPS group were increased in comparison with the control group (P<0.01). This increase was attenuated by the addition of DDB, MLT, SB and GRZ (P<0.05). The serum AST, NO and liver and spleen index were also increased significantly compared with the control group (P<0.01). Microscopic exam revealed serious histopathologic changes in the BCG combined LPS group. Hepatoxicity with associated liver enzyme elevation but histopathologic changes were attenuated by DDB, MLT, SB and GRZ. CONCLUSION: BCG combined LPS-induced hepatocyte immunotoxicity in an in vitro rat model may be a useful technique to assess the effectiveness of liver protective medications.

PurposeTo explore the left ventricle flow propagation process in patients with chronic heart failure (CHF) using velocity flow mapping. Materials and Methods Patients with CHF (n=25) were selected as CHF group. Healthy subjects (n=28) were chosen as the control group. Flow reversal interval (FRI), flow reversal rate (FRR), corrected flow reversal rate (CFRI) and flow rate in peak ejection (FRPE) were measured. Parameters related to the vortex in CHF group were compared with that in the control group. Results Compared with the control group, FRI was longer [(71±13) msvs. (113±30) ms, P<0.05], FRR and FRPE were lower [(46.85±21.35) cm2/svs. (27.90±16.77) cm2/s;(74.54±9.10) cm2/svs. (41.12±17.25) cm2/s,P<0.05] in CHF group. FRI and CFRI were positively correlated with the Tei index (r=0.812 and 0.849,P<0.01). FRI was negatively correlated with LVEF, FS, SV, CO, CI (r=-0.646--0.515,P<0.05 orP<0.01). CFRI was negatively correlated with LVEF, FS, SV, CO and CI (r=-0.685--0.456,P<0.05 orP<0.01); FRR was negatively correlated with Tei index (r=-0.604,P<0.05), and was positively correlated with LVEF, FS, SV, CO and CI (r=0.503-0.812,P<0.05 orP<0.01);FRPE was negatively correlated with Tei index (r=-0.734,P<0.01), and were positively correlated with LVEF, FS, SV, CO and CI (r=0.557-0.776,P<0.05 orP<0.01).Conclusion Velocity flow mapping can demonstratecardiac hydromechanics in patients with chronic heart failure. The heart blood flow direction reversal efficiency may be a new method for diagnosis and treatment evaluation.

Objective To assess the application of three-dimensional digital subtraction angiography (3D-DSA) in evaluation of ruptured intracranial aneurysm after clipping and to discuss the different variable use of vol-ume rendering(VR), gradient rendering (GR) and maximum intensity projection (MIP). Methods From January 2011 to December 2012 , 88 patients with 92 ruptured intracranial aneurysms were treated with clipping using titani-um clips in our hospital and followed up by both 2D-DSA and 3D-DSA. Residual aneurysms , Clips place, clips and parent arteries and stenosis of parent arteries were evaluated by volume rendering (VR), gradient rendering (GR) and maximum intensity projection (MIP). Results Among 92 clipped aneurysms, 23 residual aneurysms were found by 3D-DSA. Residual aneurysms were recorded according to the Sindou grade: 15 of gradeⅠ, 3 of gradeⅡ, 4 of grade Ⅲand 1 of grade Ⅳ. Three patients of grade Ⅲand 1 of grade Ⅳwith residual aneurysms were retreated by clipping or coiling, and 1 patient of grade Ⅲ was dead with rupture of residual aneurysm. The clips and number of clips were clearly visualized , and relationship between the clips and the aneurysms was well demonstrated by VR, GR and MIP images. VR, GR images showed the remnants clearly. Three-dimensional digital subtraction angiography did not showed accurate details of the stenosis of parent arties which required an analysis of 2D-DSA. Conclusion Three-dimensional digital subtraction angiography can be used for definite evaluation of resid-ual aneurysms after clipping, especially by VR, GR images. It is helpful to manage the residual ruptured aneurysms.

To provide insights into the mechanism for the attenuate-synergistic effect of Zuota to Tibetan medicine Renqing Mangjue, a contrasted study was carried out on the pharmacokinetics of brucine and strychnine in mice plasm, which are active and toxicant ingredient in the Tibetan medicine Renqing Mangjue. LC-MS/MS was used to detect simultaneously the concentrations of brucine and strychnine in mice plasm at-different time intervals after administration parallelly and randomly, and the pharmacokinetic software Kinetica 5. 0 was selected to non-compartmental analysis (NCA) for data, and statistical analysis software SPSS 19. 0 was used for significance test on the pharmacokinetic parameters. A reliable LC-MS/MS method was established for the determination of brucine and strychnine in blood plasma, which are consistent with the requirements of the preclinical pharmacokinetic study confirmed by the methodology. The linear concentration ranges of brucine and strychnine were 0.301-104.4 µg · L(-1) (r = 0.999 5) and 0.305-106 µg · L(-1) (r = 0.999 7), respectively; The intra-day and inter-day variable coefficients were both less than 10.0% with good precision; The average extraction recoveries of brucine and strychnine were 116.23% and 112.82%, and RSD were 3.2% and 2.3% separately;The average matrix effects of brucine and strychnine were 122.48% and 116.36%, and RSD were 7.7% and 4.4%, respectively. The pharmacokinetic results showed that AUCtot of brucine and strychnine in Zuota group were both increased remarkably (P < 0.05), and the Cmax of brucine in Zuota group was about 5.25-fold higher than that of brucine in non-Zuota group (P < 0.05). The Tmax of brucine and strychnine reduced to one-eighth and one-quarter respectively compared with those in Non-Zuota group. In addition, the eliminations of brucine and strychnine in vivo were accelerated after the compatibility of Zuota. A significant difference (P < 0.05) occurred at the MRT0-t, of brucine, while the MRT0-∞ and Lz of strychnine were statistically significant upon the inspection level α = 0.1. It was found that the absorption degree of brucine and strychnine in Zuota group increased in the range of the safe dose (or concentration), while their elimination rates were accelerated, which may be one of the mechanisms for attenuate-synergistic effect of Zuota to Tibetan medicine Renqing Mangjue.

Objective: To observe the effect of the intravenous infusion of vasostatin-2 (VS-2) on hemodynamics in experimental rats with spontaneous hypertension (SH).
Methods: A total of 36 (14-16) weeks male SH rats with the mean body weight at (160-250) g were randomly divided into 6 groups:①Control group, the rats received normal saline (100μl/kg),②Catestatin (20μg/kg) group,③VS-2 (5μg/kg) group,④VS-2 (10μg/kg) group,⑤VS-2 (20μg/kg) group and⑥VS-2 (40μg/kg) group. n=6 in each group. The average blood pressure (BP), heart rate (HR) and barorelfex sensitivity (BRS) were monitored and compared upon VS-2 treatment and between VS-2 and catestatin treatments in conscious and freelance rats.
Results: Compared with prior treatment, VS-2 (20μg/kg) and VS-2 (40μg/kg) could obviously decrease the HR, BP and BRS in SH rats. In VS-2 (20μg/kg) group, HR by bpm was (341.3 ± 19.3) vs (365.5 ± 25.5), BP by mmHg was (133.0 ± 8.9) vs (147.5 ± 11.2) and BRS by ms/mmHg was (0.52 ± 0.18) vs (0.37 ± 0.12);in VS-2 (40μg/kg) group, HR was (348.8 ± 30.8) vs (374.5 ± 34.8), BP was (131.5 ± 9.3) vs (151.7 ± 10.8) and BRS was (0.53 ± 0.05) vs (0.38 ± 0.03), all P<0.01. Catestatin treatment could also decrease the HR as (318.7 ± 13.4) vs (365.5 ± 25.5), BP as (119.7 ± 7.3) vs (147.5 ± 11.2) and BRS as (0.58 ± 0.15) vs (0.35 ± 0.11), all P<0.01. Compared with catestatin (20μg/kg), the rats received VS-2 (20μg/kg) had the weaker reduction of HR as (318.7 ± 13.4) vs (341.3 ± 19.3), BP as (119.7 ± 7.3) vs (133.0 ± 8.9), all P<0.01, while BRS was similar as (0.58 ± 0.15) vs (0.52 ± 0.18), P>0.05.
Conclusion: Intravenous infusion of VS-2 may obviously affect HR, BP and BRS in experimental SH rats;compared with the same dosage of catestatin, VS-2 had the weaker reduction of HR, BP and BRS.
