Objective: To observe the clinical curative effect of narrow band ultraviolet combined infrared with 8-Methoxypsoralen for the treatment of vitiligo,to seek a new method for the treatment of vitiligo. Methods: Sixty cases of vitiligo patients were randomly divided into experimental group and control group. The experimental group adopted 365-nm narrow band ultraviolet LED combined 850-nm infrared LED with 8-Methoxypsoralen for the treatment of vitiligo, the control group adopted 365-nm narrow band ultraviolet LED irradiation combined with 8-Methoxypsoralen for the treatment of vitiligo, the clinical curative effect of two group were observed when treated with 1 months,2 months. Results:After 2 months of treatment, the efficiency rate of the experimental group was 66.67%, higher than that of the control group with an efficiency of 40%, the difference was statistically significant(x2=4.653, P<0.05). Conclusion: The clinical efficacy of narrow band ultraviolet combined infrared with 8-Methoxypsoralen for the treatment of vitiligo is better than that of narrow band ultraviolet combined with 8-Methoxypsoralen in the treatment of vitiligo.

OBJECTIVE:To establish the quality standard for Catechu anti-diarrhea ointment.METHODS:TLC was applied to identify the properties of medicinal ingredients in the formula;HPLC was adopted to determine the main effective ingredient catechin in Catechu.A stability test was then conducted.RESULTS:TLC determination revealed good results.Catechin showed a good linear relationship at a range of 0.364～ 1.82? g.The average recovery was 98.94%(RSD=1.28%,n=5).CONCLUSION:The standard can be applied to the quality control of Catechu Anti-diarrhea ointment.

Objective To establish a method for determining the content of Danshensu and Protocatechuic Aldehyde in Huoxue capsule. Methods The HPLC method was adopted for the determination. Danshensu and Protocatechuic Aldehyde were used as the standard. Detection wave length was set at 280 nm,the mobile phase consisted of methanol-0.5 % HAc (30∶70). Results The linear range of Danshensu was 0.421～3.364 ?g and Protocatechuic Aldehyde was 0.212～1.699 ?g. The average recovery rate of Danshensu was 100.05% with RSD of 3.07% and Protocatechuic Aldehyde was 99.39% with RSD of 1.62%. Conclusion This method is accurate,specific and reliable for the quality control of Huoxue capsule.

Objective:To analyze the clinical application of Bozhi glycopeptides to provide reference for its rational use in clinics . Methods:The related literatures of Bozhi glycopeptides from the databases of CNKI , Wanfang and VIP were retrieved .The main clinical application ( the number of literatures on the same disease entities was above 3) and ADR were analyzed and evaluated .Results:A total of 163 literatures were found, including 137 clinical application and 11 ADR case reports.The disease with the number of literatures a-bove 3 included condyloma acuminatum (9 literatures), herpes zoster (6 literatures), hand-foot-mouth disease (6 literatures), psoriasis vulgaris (6 literatures), lung cancer (5 literatures), repeated respiratory infection (4 literatures) and hepatitis B (9 literatures), and the total number was 45.Among them, 32 literatures (1 772 cases) involved ADR, and 49 cases (2.77%) of ADR were reported, and the main performance was skin and its appendages damage (10 cases, 20.0%).Totally 11 ADR case reports mainly involved rigors and fever (13 cases, 37.2%).Conclusion:Bozhi glycopeptides as an adjuvant drug is mainly combined with other drugs to enhance the effi -cacy of mian drugs in clinical application , which shows low incidence of ADR mainly including skin and its appendages damage .

Pubmed (1990-2008) and China Journal Full-text Database (CJFD) (1998-2008) were searched for relevant articles on localization of skin stem cells. A total of 44 articles revealed that hair follicle bulge cells that are label-retaining cells regenerate themselves by division and can give rise to differentiated progeny. They did not express characteristic markers of differentiated cells, but stem cells markers. Therefore hair follicle bulge region was considered to be epidermal stem cells niche. Hair follicle dermal sheath housed multipotent and plastic stem cells, considered to be dermal stem cells niche. Hair follicle dermal papilla interacted with dermal sheath to induce the formation of hair follicle. It is believed that precursor cells in dermal papilla harvested from dermal sheath stem cells are the active daughter cells. Whether skin stem cells are present in hair follicle and hairless region is under debate. Some studies found that skin stem cells were detected in the basal layer of epidermis in hair follicle.

OBJECTIVE:To study the anti-inflammation effects of cacumen biotae water decoction on mice with auricle and ab-dominal inflammation. METHODS:Mice were randomized into a normal control group,a model group,a positive control group (0.25 g/L aspirin)and cacumen biotae high-dose,medium-dose and low-dose [1,0.5 and 0.25 g(medicinal materials)/L] groups, respectively marked as groups A,B,C,D,E and F,with 10 mice in each group. The mice were given drugs ig for 5 consecutive days. The models of auricle and abdominal inflammation were established for all groups except the normal control group. The con-tents of tumor necrosis factor α(TNF-α)and interleukin 1(IL-1)in the serum of mice with auricle inflammation were determined, and the swelling degree and swelling rate were calculated. The contents of TNF-α,IL-1 and acid-sensing ion channels 1a(ASIC1a) in the liver tissues of mice with abdominal inflammation and the concentration of proteins in the peritoneal lavage fluid(ΔA)there-of were detected. RESULTS:For mouse models of auricle inflammation,the contents of TNF-α and IL-1 in serum in group B were higher than in group A;the swelling degree and swelling rate and the contents of TNF-α and IL-1 in groups C,D,E and F were lower than in group B,and those of group E and F were higher than in group C. There were statistical differences(P<0.05). For mouse models of abdominal inflammation,the contents of TNF-α,IL-1 and ASIC1a in liver tissues and ΔA in group B were higher than in group A;the contents of TNF-α,IL-1 and ASIC1a as well as ΔA in groups C,D,E and F were lower than in group B. There were statistical differences(P<0.05). CONCLUSIONS:Cacumen biotae water decoction has anti-effect on acute auricle and abdominal inflammation by a mechanism which may be related to decreasing TNF-α,IL-1 and ASIC1a.

BACKGROUND: The expression and significance of transforming growth factor-alpha (TGF-α) and epidermal growth factor receptor (EGF-R) in different diseases are different.OBJ ECTTVE: To investigate the expression of TGF-α and EGF-R in human liver cirrhosis tissues.DESIGN : Non-randomized controlled trial.SETTING: Department of General Surgery, Tangdu Hospital, Fourth Military Medical University of Chinese PLA.MATERIALS: This trial was carried out in the Department of Pathology, Xijing Hospital, Fourth Military Medical University of Chinese PLA during March 2003 to May 2004. Sixty-three samples of human liver cirrhosis tissue were obtained from Department of General Surgery, Xijing Hospital, Fourth Military Medical University of Chinese PLA (Informed consents were obtained). Five human normal liver tissues were obtained form autopsy in Department of Pathology, Fourth Military Medical University of Chinese PLA (patients with liver diseases were excluded).METHODS: Sixty-three samples of human liver cirrhosis specimens and five human normal liver tissues were studied with immunohistochemical method and in situ hybridization technique. The positive rates of TGF-α and EGF-R were calculated and managed statistically.MAIN OUTCOME MEASURE: Detection of the expressions of TGF-α and EGF-R in liver cirrhosis tissues were detected with immunohistochemical method and in situ hybridization technique.RESULTS: The expression rate of TGF-α and EGF-R in 63 samples of human liver cirrhosis tissues was 84% (53/63)and 52% (33/63) respectively. These positive granules were brown and most of them were in cytoplasm of hepatocytes.There was significantly positive correlation between TGF-α and EGF-R (r =0.32,P ＜ 0.05). In five normal liver tissues,TGF-α and EGF-R were not detectable in hepatocytes and bile ducts. In situ hybridization showed the levels of TGF-αmRNA and EGF-R mRNA were higher (86%, 54%) than those of immunohistochemistry. There was no significant difference between two detective methods (P＞0.05).CONCLUSrON: Liver cirrhosis might be under the autocrine regulation of TGF-α/EGF-R. Increasing expression of TGF-αand EGF-R might be one of important factors in liver cirrhosis pathogenesis.
