This study was aimed to explore the clinical efficiency of modified Xiao-Y ao (XY) powder and acupuncture in the treatment of diarrhea-predominant irritable bowel syndrome (D-IBS). A total of 90 D-IBS patients were randomly divided into the treatment group and control group, with 45 patients in each group. Patients in the treatment group received acupuncture combined with modified XY powder. Patients in the control group received oral administration of montmorillonite powder, compound glutamine enteric-coated capsules, compound azintamide enteric coated tablet. Four weeks were one treatment course. After two treatment courses, the pretreatment and posttreatment symptom score, the score of Hamilton Depression Rating Scale (HAMD)/(HAMA), and the overall efficacy were compared. The results showed that compared with pretreatment, clinical symptoms were improved in varying degrees after treatment in both groups (P < 0.05 or P < 0.01). HAMD and HAMA were significantly decreased (P < 0.05). The treatment group had obvious advantages compared to the control group (P < 0.05). The overall efficacy of the treatment group was 91.11%, which was significantly higher than the control group of 68.89%(P < 0.05). It was concluded that modified XY powder and acupuncture can quickly relieve gastrointestinal symptoms, improve anxiety and depression. It is an effective treatment method for D-IBS.

This study was aimed to observe the clinical curative effect of Qing-Re Li-Shi Hua-Y u (QRLSHY) decoction combined with acupuncture in the treatment of chronic pelvic inflammatory disease (PID) with syndrome of damp-heat and blood-stasis. A total of 120 cases were randomly divided into the acupuncture combined with traditional Chinese medicine (TCM) group, TCM group, and acupuncture group, with 40 cases in each group. The TCM group was given oral administration with QRLSHY decoction. The acupuncture group was given acupuncture on SP6-Sanyinj iao and RN6-Qihai . The acupuncture combined with TCM group was given oral administration with QRLSHY decoction and acupuncture treatment. The treatment course of each group was 2 months. The ob-servation was made on clinical efficacy, clinical symptoms, body signs, changes of laboratory indexes, and relapse rate of three groups. The results showed that compared with pretreatment, the total effective rate of the acupunc-ture combined with TCM group, TCM group and the acupuncture group was obviously increased after treatment (P< 0 . 05 ) . Compared with pretreatment , the clinical symptoms and body signs such as abdominal pain , abdominal bulge, backache, leucorrhea increased, dysmenorrhea, menstrual disorders, lassitude, appendix thickening, pelvic tenderness, and pelvic mass were significantly improved in all three groups (P < 0.05). After treatment, clinical symptoms and body signs of the acupuncture treatment with TCM group had more obvious advantages than the TCM group and the acupuncture group ( P < 0 . 05 ) . Compared with pretreatment , the cervical or vaginal mucus pu-rulent secretion, vaginal wet film mirror of white blood cells, white blood cell count, absolute neutrophil count of all three groups were significantly improved ( P < 0 . 05 ) . After treatment , the acupuncture combined with TCM group had more obvious advantages than the TCM group and acupuncture group ( P < 0 . 05 ) . The relapse rate of the acupuncture combined with TCM group was obviously lower than the TCM group and the acupuncture group 6 months, 9 months, and 12 months after treatment (P < 0.05). It was concluded that QRLSHY decoction combined with acupuncture had obvious clinical curative effect in the treatment of chronic PID with syndrome of damp-heat and blood-stasis.

RESUMEN
Objective To study the survival and melanogenic potential of human melanocytes reversibly immortalized via SV40T antigen gene and Cre/loxP system in Guinea pigs. Methods The supernatants of retrovirus vector Cre-ERT2 were used to infect melanocytes which had been successfully transfected by SV40TAg gene (MCT), then the expression of Cre recombinase was induced with tamoxifen in infected cells; subsequently, the surviving cells, which were named as MCTC, were subjected to expansion culture. Guinea pigs were utilized to establish animal models of vitiligo, then MCTC and primary melanocytes were transplanted respectively into the animal models. The repigmentation at the transplanted area was observed with naked eyes successively until 3 months after the transplantation when tissue samples were obtained from implanted area and nonimplanted area of guinea pigs and subjected to Masson-Fontana silver stain and Hematoxylin-eosin stain for the analysis of melanocyte distribution and melanin deposition in epidermis. Results Repigmentation started 4 weeks after the transplantation, and dark or brown patches, which ranged in size from 0.5 to 1 cm, were observed in the implanted area 3 months after the transplantation. The repigmentation rate was of no significant difference between pigs transplanted with MCTC and those with primary melanocytes (82.5% vs 76.7%, P > 0.05). Pathological examination revealed melanin deposition in the basal layer of epidermis and some hair follicles in transplanted area. Conclusions SV40T antigen gene combined with Cre/loxP site-specific recombinase system can induce the reversible immortalization of human melanocytes, and the immortalized melanocytes have a favorable profile of biological safety and similarity in survival rate and melanogenic potential to primary melanocytes.
