Objective To study CTLA4Ig gene expressed in dermal papilla cells and to provide evidence for immune tolerance after dermal papilla cells transplantation. Methods CTLA4Ig cDNA was transferred into dermal papilla cells by recombinant adenovirus vector, and the dermal papilla cells containing CTLA4Ig gene were transplanted into mice skin. The target gene expression was detected by histological and immunohistochemistry technique. Results CTLA4Ig protein was expressed in plasma 6 hours after gene transfection and increased gradually. When the transferred papilla cells were transplanted into mice skin the gene began to express in 24 hours and lasted for 2 weeks. No rejection was observed. Conclusion Dermal papilla cells containing CTLA4Ig gene can survive in vitro and in vivo and express CTLA4Ig for a long time.

OBJECTIVE:To provide reference for rational use of antibiotics in the clinic. METHODS:The study quarterly count the dosage of carbapenems,the department distribution of cultured K. pneumonia (271 strains) during Oct. 1st 2013-Sept. 30th 2014,and it’s resistant rates to carbapenems and then investigate the correlation of dosage of carbapenem and drug-resistance of K. pneumoniae. RESULTS:Carbapenem drugs are mainly used in these departments,such as neurosurgery department,ICU and the departments of transplantation and respiratory. Carbapenem-resistant K. pneumonia was also detected in these departments. More-over,with the usage of carbapenem increased by from 64.24% to 360.63%,and the resistant rates of K. pneumonia increased by nearly 10%. CONCLUSIONS:The resistance rates of K. pneumonia is positively related to the amount of carbapenem;the amount control of carbapenems can delay the generation of K. pneumonia.

Objective To investigate the interaction between dermal papilla cells and hair follicle epithelial cells,to understand the regulation of hair follicle growth cycle, and to find out the pathway of hair follicle reconsitution in vitro and in vivo. Method Human dermal papilla cells and hair follicle epithelial cells were cultured in the same or separated compartments.The cells were counted in different phases and the cell growth pattern was observed. Results The two kinds of cells could stimulate the proliferation each other.Human hair follicle epithelial cells could induce dermal papilla cells to aggregate and form dermal papilla－ like structure. Conclusion There is a mutual interaction between the epithelial cells and dermal cells of the hair follicle.The growth and development of hair follicle is regulated by the interaction of these cells.

Objective To explore the curative effects, side effects and complications of arterial embolization for the treatment of uterine leiomyoma.Methods Bilateral uterine arterial embolization with silk particles of 350～500 ?m was performed in 16 cases of uterine leiomyomas with uterine hemorrhage as the main complaint.Results 15 patients underwent technically successful embolization. No serious complications occurred. The patients were followed up for 3～12 months. Menses returned to regular cycle. In the patients with anemia, the hemoglobin concentration rose up to normal level. The sizes of uterine leiomyoma decreased by 52% after 6 months of the treatment.Conclusions Uterine arterial embolization is an effective and less invasive therapy with no serious complications for patients with uterine leiomyoma, especially for presentation of the uterus.

OBJECTIVETo explore the efficacy and effect mechanism of the combined therapy of acupuncture and tapping method in the treatment of obesity and hyperlipidemia of liver qi stagnation and spleen deficiency pattern in the patients.

METHODSOne hundred and four female patients were randomized into a combined therapy of acupuncture and tapping (combined therapy group) group method and an acupuncture group, 52 cases in each group. In the acupuncture group, acupuncture was applied to Qimen (LR 14), Taichong (LR 3), Zhangmen (LR 13), Taibai (SP 3), Zusanli (ST 36), Geshu (BL 17), Ganshu (BL 18), Pishu (BL 20), etc. In the combined therapy group, on the basis of acupuncture treatment, the tapping method with plum blossom needle was used at each acupoint. The treatment was given once every two days, continuously for 3 months in the two groups. The indices were observed, including the obesity indices, such as body mass, body mass index (BMI), body fat percentage (F%) and obesity degree (A); the blood lipid levels such as total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL) and high density lipoprotein (HDL); the fat-islet axie relevant indices such as fasting plasma glucose (FBS), fasting leptin (FLP), fasting insulin (FINS), insulin sensitive index (ISI), insulin resistance in- dex (Homa IR), insulin secretion index (Homa-β) and autonomic nerve function index (Y value) before and after treatment in the patients of two groups. The efficacy was compared between the two groups.

RESULTSThe total effective rates were 96.2% (50/52) and 84.6% (44/52) in the combined therapy group and the acupuncture group respectively, without significant difference in comparison (P > 0.05). Obesity indices, blood lipid indices, fat-islet axie relevant indices and autonomic nerve function indices were all improved after treatment as compared with those before treatment in the two groups (P < 0.01, P < 0.05), and the improvements in the combined therapy group were much more significant (P < 0.01, P < 0.05).

CONCLUSIONThe combined therapy of acupuncture and tapping method achieves the double effects of weight loss and lipid loss in the treatment of obesity combined with hyperlipidemia. The effect mechanism is possibly related to the positive regulations of blood glucose, lipid metabolism and fat-islet axie in the patients.

BACKGROUND: Hepatocyte growth factor (HGF) promotes neurite outgrowth from neocortical explants, and supports neuronal survival under serum-free condition. Thus, HGF can mediate neurotrophic function as a novel neurotrophic factor.OBJECTIVE: To establish an in vitro injury model with a semi-solid culture system for the purpose of improving the evaluation of neurite regeneration of transected spinal cord neurons from rat embryo, and investigate the effect of HGF on neurite regeneration.DESIGN: Randomized controlled study.SETTING: Hematology Laboratory of Radian Medical Institute of Academy of Military Medical Sciences of PLA.MATERIALS: The experiment was carried out at the Hematology Laboratory of Radian Medical Institute of Academy of Military Medical Sciences of PLA from August 2004 to May 2005. Wistar fetal rats of 14-16 days old were provided by Animal Center of Academy of Military Medical Sciences of PLA. Tail collagen was extracted from adult male Wistar rats with body mass of (250±50) g.METHODS: ① Rat tail type Ⅰ collagen substrate was prepared and spread on a culture dish, cut into about 0.5-1.0 mm3 slices, then spinal cord slices of 15-day-old fetal Wistar rat were explanted on the primary culture. Five days later, the outgrowing processes were severed, then a block of collagen, with the surface area of 2 mm2 and 200 μm away from the slice, was removed and the vacancy was replaced with a fresh collagen block of 2 μL after aspirating the medium. The fresh collagen block could be solidified and then fresh liquid medium was added as the secondary culture. The regeneration of neurite was observed by microscopy at 0, 1, 6,12 and 24 hours after severing. ② The medium was changed with 0.5% N3-conditioned medium. 10 μg/L HGF was added in the experimental group, and 0.5% N3-conditioned medium was added in the control group.The status of regeneration was evaluated by the average value of 3 longest regenerative neurites for each slice. There were 12 slices in each group.The status of neurite regeneration was calculated and was evaluated 24 hours later.MAIN OUTCOME MEASURES: ① neurite regeneration in situ; ②comparisons of neurite regeneration between control group and experimental group.RESULTS: ① Neurite regeneration in situ: The neurites disintegrated near the severing line immediately following the transection injury. This process persisted about 1-2 hours and the distance away from the severing line was about 20 μm. Then the proximal end of neurites would swell and thicken. At this time neurites stopped collapsing and neurite regeneration began. Their regenerating rate would quicken at 12 hours after severing. Regenerating neurites were more branching and curlier as compared with original neurites. ② Comparisons of neurite regeneration between control group and experimental group: The average length of regenerative neurites was more in the experimental group than that in the control group [(375±96) μm, (200±75) μm, P ＜ 0.05].CONCLUSION: ① We establish a simple, economic model to evaluate neurite regeneration. ② By this model, we prove that HGF can promote neurite regeneration.

Objective To explore the protective effect of HGF on primary cultured spinal neurons in vitro.Methods Cultured neurons were transfected with Ad-GFP or Ad-HGF in different multiplicity of infection(MOI),then flow cytometer and PI-Hoechst double stains were used to assay transfer rate or to determine the status of cells respectively.ELISA was used to detect the expression of HGF in Ad-HGF transfected neurons,and the activity of neurons was judged by neutral red stain,MTT and NSE-ELISA methods.Results After transfection with Ad-GFP in MOI of 50,the transfer rate was high as detected by flow cytometer,and the status of cells was well as judged by PI-Hoechst double stain.The results of ELISA showed that HGF was expressed in medium.After transfection with Ad-HGF,the activity of neurons was better than neurons without treatment(P
