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.

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.

Objective To understand the mechanism of cerebral energy failure after hypoxia ischemia at the molecular level and to establish the protocol for the safe and effective treatment of hypoxic-ischemic encephalopathy(HIE).Methods One hundred neonatal rats were divided into normal control group and hypoxic-ischemic(HI) group. SD rats of both groups were decapitated at the time of 2 h,24 h,48 h,72 h and 7 d after HI.These tissues of cerebrum,cortex and hippocampus were taken out to explore the influence of HI on the expression of GLUT1 and GLUT3 genes with the method of RT-PCR.Results There was an enhancement in the expression of GLUT1 and GLUT3 genes with the increasing of day age. The expression was more intense in hippocampus than that in cortex. However, HI could significantly enhance the expression of GLUT genes. The expression was higher in cortex than that in hippocampus. The expression of two genes reached the peak at 24 h after HI, but was significantly lower than that in control group at 7 d after HI.Conclusion The increased expression of GLUT genes can maintain the energy supplement for the brain and delay a cascade reaction of cerebral energy failure.

Objective To observe the changes of expression and activity of heme oxygenase-1(HO-1) in lung tissue of preterm rats exposed to hyperoxia,and explore the role of HO-1 in hyperexia-induced lung injury of preterm rats.Methods Three-day-old preterm rats of standard SD were randomly assigned to hyperoxia group and air group.At the third and 7th day of exposure,the expressions of HO-1 mRNA were detected by means of reverse transcription polymerase chain reaction and the cellular distribution and expressions of HO-1 protein in the lung were measured by immunohistochemical techniques,respectivesly,and the active of HO-1 was determined also.Results On the third day,in air group,the expressions of HO-1 mRNA(0.17 ?0.08),HO-1(7.23?4.63)were mildly expressed and the activity of HO-1 was(4.32?1.57) nmol/(mg?h);compared with those of air group,the expression of HO-1 mRNA in hyperoxia group(0.72?0.33) was significantly increased(Pa

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.
