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.

The occurrence of medical safety (adverse) events were closely related to working life and qualifications;among 578 medical, nursing and drug-related medical safety (adverse) events,the incidence of adverse events was 71.11% in 5-year working life group,and that was 73.18% in junior titles group. CONCLUSIONS:Various professionals should strictly implement procedure and regulations,strengthen communication and education in daily work,and improve professional knowledge and skills so as to prevent the occurrence of adverse event completely.

Aim To study the characteristics of the binding reaction of Troxetutin with bovine serum albumin (BSA) by fluorescence and ultra violet-visible absorption spectra.Methods The quenching mechanism of the fluorescence of BSA by troxerutin was studied with fluorescence.To determine the dynamic quenching constants and static binding constants,the Stern-Volmer equation and the double reciprocal Lineweaver-Burk equation were applied. The number of binding site was calculated with double logarithmic equation and the main binding force was discussed by thermodynamic equations. The binding distance and energy transfer efficiency between donor (BSA) and acceptor (troxerutin) were obtained effectively quenched fluorescence of BSA via static quenching processes. The binding constant Ka was calculated to be in the order of 106,indicating a strong interaction between Troxerutin and BSA. The number of binding site was approximately equal to 1,the binding distance was 1.97 nm,the energy transfer efficiency was 0.529,and the binding force was mainly hydrophobic force.Conclusion Troxerutin effectively quenchs the intrinsic fluorescence of BSA via static quenching mechanism,and the binding is mainly driven by the hydrophobic interaction.

Objective To study the biodistribution of anti-HER-2/neu monoclonal antibody Herceptin labeled by 131I(131I-Herceptin) in healthy KM mice and nude mice bearing human ovarian cancer xenografts and radioimmunoimaging (RII) of the nude xenografts-bearing mice.Methods 131I-Herceptin was prepared using Iodogen method.The labeling efficiency, radiochemical purity, stability and immunocompetence were measured.The percentage activity of injection dose per gram of tissue (%ID/g) and the radioactivity ratio of tumor to non-tumor tissue (T/NT) were calculated for each time point.The optimal time for imaging was investigated by comparing the 131I-Herceptin SPECT for the nude mouse models bearing ovarian cancer xenografts at different time points.Results The labeling efficiency and radiochemical purity of 131I-Herceptin were 89.8% and 98.4%, respectively.The labeling was stable and had good immunocompetence.131 I-Herceptin was cleared rapidly mainly through liver, spleen and kidneys, consistent with first order two-compartment model.The uptake of 131I-Herceptin in the tumors bearing human SKOV-3 xenografts was much higher than that in nontumor tissue.The% ID/g was 18.08 in the tumor at 24 h post injection.The T/NT ratio increased with time and was 27.27 at 72 h post injection.The tumors in nude mice bearing SKOV-3 xenografts could be visualized on 131I-Herceptin SPECT imaging 2 h post injection; definitely identiffed 48 h post injection and the radioactivity ratio of tumor to contralateral tissue was 11.44 at 120 h post injection.However, the tumor in nude mice bearing HO-8910 xenografts did not show abnormal uptake of 131 I-Herceptin at each time point.Conclusions 131 I-Herceptin is a good radiopharmaceutical targeting SK-OV-3 xeuografts and it may be useful in imaging carcinoma of ovary and target therapy of its metastases with high HER-2/neu expression.

Objective To compare anatomically the potential incidences of injury to the nerve roots of ventral and dorsal rami caused by the transarticular screws and Magerl lateral mass screws in the fixation of subaxial cervical spine.Methods Fixations with the transarticular screws and Magerl lateral mass screws were performed in this study.For each kind of fixation,20 screws were inserted from C3 to C7 in two specimens.A 20-ram long screw was used to over-penetrate the ventral cortex.The anterolateral aspect of the cervical spine was carefully dissected to allow ob- servation of the screw-ramus relationship.Results The overall percentage of nerve violation was significantly lower in the transarticular screw fixation(45%)than in the Magerl lateral mass screw fixation(90%).The difference was sta- tistically significant between the two fixation methods(P＜0.05).The greatest percentages of nerve violation caused by the transarticular screws and lateral mass screws were found at the dorsal ramus,25% and 45%,respectively. Conclusion The potential risk of nerve root violation caused by the transarticular screw technique is lower than that by the Magerl lateral mass screw technique in the lower cervical spine.
