The resource of rare and endangered medicinal plant Swertia mussotii Franch. in Tibet, Qinghai and Sichuan province were surveyed by ways of documents, interview, quadrat and market investigation. The results indi-cated that Swertia mussotii Franch. mainly distributed in Zuogong and Mangkang of Tibet, Yushu of Qinghai province, Shiqu, Daofu, Kangding, Maerkang, Jinchuan and Xiaojin of Sichuan province. According to the height above sea level, the distribution altitude was from 2 300 m (Kangding of Sichuan province) to 3 900 m (Mangkang of Tibet). There are distributions of Swertia mussotii Franch. within the scope of 2 600 m. The illumination, water, soil, temperature and altitude had significant influence on the distribution, growth and reserve of Swertia mussotii Franch. from different angles. In recent years, there was huge increase of market requirement in Swertia mussotii Franch. which were used in Tibetan medicine Zangyinc he n. Excess collection was the primary cause of rapid decreasing in resource of Swertia mussotii Franch.. It was suggested to strengthen the management of rational collection, as well as to accelerate the development of cultivation and production.

OBJECTIVETo explore the effect of Chang'an No. I Recipe (CA) on 5-hydroxytryptamine signal system and mRNA expression levels of hippocampal brain derived neurotrophic factor (BDNF) in visceral hypersensitivity model rats with irritable bowel syndrome (IBS).
METHODSIBS visceral hypersensitivity rat models were established by combined chronic restraint stress and forced swimming. Successfully modeled rats were randomly divided into the model group, the Dicetelgroup (27 mg/kg) , the Fluoxetine group (3.6 mg/kg), the high dose CA group (22.6 mg/kg), the medium dose CA group (11.3 mg/kg), and the low dose CA group (5.7 mg/kg) according to body weight, 9 in each group. Besides, a normal control group with 10 rats was set up. Corresponding medication was administered to rats in each treatment group. Equal volume of physiological saline was administered to rats in the model group by gastrogavage. All medication was performed once per day for a total of 14 days. Pain threshold was determined by abdominal withdrawal reflex (AWR). Changes of colon 5-HT levels were determined by immunohistochemical assay. mRNA expression levels of hippocampal 5-hydroxytryptamine 1A receptor (5-HT1a) and BDNF were detected by immunofluorescent RT-PCR.
RESULTSCompared with the normal control group before treatment, pain threshold was obviously lowered in proctectasia rats of each group (P < 0.01). Compared with the normal control group after treatment, pain threshold was obviously lowered in rats of the model group; colon 5-HT levels, mRNA expression levels of hippocampal 5-HT1a and BDNF were obviously elevated (P < 0.01). Compared with the model group, pain threshold was obviously elevated in the Fluoxetine group and all CA groups; colon 5-HT levels were obviously reduced in the Dicetel group, high and medium dose CA groups (P < 0.05, P < 0.01); mRNA expression levels of hippocampal 5-HT1a and BDNF were obviously reduced in each CA group (P < 0.01); mRNA expression levels of hippocampal BDNF were obviously reduced in the Fluoxetine group (P < 0.01).
CONCLUSIONSThe target points of CA were involved in brain and gut. CA could reduce pain threshold of proctectasia rats, down-regulate colon mucosal 5-HT levels, and lower mRNA expression levels of BDNF and 5-HT1a in rat hippocampus.

AIM: To investigate effects of rBMMSC on hematopoiesis and immune reconstitution after allo-hematopoietic stem cells transplantation (HSCT). METHODS: Allogeneic BMT model from Fischer344 rats (RT-1Al) to Wistar rats (RT-1Au) was established. The effects of MSCs on hematopoietic reconstitution and immune reconstitution were studied by observing the survival rate, peripheral blood counts, thymus counts, spleen counts, bone marrow counts and immune function analysis at 30 days after transplantation. RESULTS: 1. Cotransplantation of MSCs and bone marrow (BM) was demonstrated to improve hematopoietic reconstitution. Lymphocyte and platelet counts in peripheral blood in cotransplantation groups were higher than those in control groups. More bone marrow neucleated cells were also observed in cotransplantation groups. 2. Cotransplantation of MSCs and BM improved immune reconstitution. First, overall thymic cellularity and spleen cellularity significantly increased in cotransplantation groups at day 30. Secondly, cotransplantation improved immune functional recovery. Non-specific lymphocytes proliferation reaction induced by ConA and LPS increased in cotransplantation group, and so did for allogeneic mixed-lymphocyte reaction. CONCLUSION: Hematopoietic reconstitution and immune reconstitution were significantly enhanced by MSCs cotransplanted with BM.
