The origin and development of umbilical therapy in traditional Chinese medicine is explored from related literature in the history. As a result, the Shang period is regarded as initial period of umbilical therapy, while periods from Han Dynasty, Jin Dynasty and Southern-Northern Dynasties to Sui Dynasty and Tang Dynasty could be taken as stage of primary development. Time from Song Dynasty, Jin Dynasty and Yuan Dynasty to Ming and Qing Dynasties is believed as mature stage. Also the manipulation, application principle, indications and contraindications of umbilical therapy are explained. A brief overview of modern development of umbilical therapy is also described.

and each of the resistant strains was resistant at least to 5 antibiotics.13 strains out of the 28 harbored plasmids ranging from 1 to 6 in number and 105 Md to 2.7 Md in molecular weight.The plasmid with 50 Md was the most popular one in this study,which may be the epidemic plasmid in the urologic unit.It was also found that 2 different species of bacteria isloated from the patients with infection of the urinary tract showed identical plasmid profile,which indicates that these 2 patients may be associated with each other.

Limonin existed in citrus fruits has been shown to have anti-bacterial, anti-viral, anti-feedant, anti-nociceptive, anti-inflammatory activities and anti-carcinogenic activities. But the clinical use is limited by its low bioavailability. The aim of this study is to observe the absorption and secretion transport mechanisms of limonin in intestine which can pave the way for the further study and clinical use. The transport characteristics and mechanisms of limonin in rat were studied by in situ intestine perfusion and in vitro Caco-2 cells method. The intestinal absorption of limonin was probably via a facilitated diffusion pathway which was poor and without segment-selection. Verapamil and ketoconazole improved the absorption remarkably according to the result of in vitro Caco-2 cells study; however, probenecid had no significant effect on the absorption. The P-gp efflux and CYP3A4 metabolism were involved in the poor intestinal absorption and low bioavailability of limonin. The exploration of the intestinal absorption mechanism is crucial to the design of dosage form and clinical use of limonin.

Objective: To study the antipyretic action of Dipseudoephedrine Glycyrrhizin and its effect on heart rate and blood pressure of rats.Methods: The model of pyretic rabbit was established by diphtheria-pertussis-tetanus triple vaccine,and to observe the effect of Dipseudoephedrine Glycyrrhizin on temperature of rabbit. Two-path physiological recorder was used to measure heart rate and blood pressure.Results: The experiment proved that Dipseudoephedrine Glycyrrhizin can decrease the anus temperature of pyretic rabbit obviously.Dipseudoephedrine Glycyrrhizanate had no remarkably effect on heart rate and blood pressure.Conclusion: Dipseudoephedrine Glycyrrhizin has antipyretic action and has no effect on heart rate and blood pressure within studied dose.

Object The immunoregulation function was studied in experimental animals to observe the effect of single and/or combined use with Radix Aconiti (RA) and Radix Stephaniae Tetrandrae (RST). Methods The response of delayed type hypersensitivity (DTH) in mice, the phagocytosis of abdominal macrophages (M?) in mice, and the production of special antibodies in mice were observed. Results The two Chinese materia medica (CMM) in combination use could induce the increasing of phagocytosic function of M? hypoimmunitic model mice, the inhibiting on the responses of DTH in the hyperimmunitic model mice and the non immunosuppressive treated mice. On the production of special antibodies in mice, the enhance effect was found in RA used in single, and the suppressive effect was found when using the combination of the two CMM. Conclusion In accordance with the mechanism of the disorder between the anti inflammation effect and the induce inflammation effect to arthritis in the immune system, these data indicate that the bidirectional effect of combination of the two CMM used on the immune responses, may be the involved mechanism on treating arthritis.

Objective To explore the biological characteristics and karyotype of bone marrow-derived mesenchymal stem cells(MSCs)in patients with systemic lupus erythematosus(SLE)and hematopoietic sup- port of MSCs.Methods MSCs were isolated from bone marrow of 11 SLE patients and 6 healthy controls by density centrifugation and adhesive culture in vitro.The surface markers were detected by flow cytometry (FCM).The morphological changes of MSCs were observed in primary and passage cultures.The growth curves were assayed.The karyotype of MSCs was detected by blocking cellular mitosis with colchicines.The MSCs from SLE patients and healthy controls were infused to ICR mice after high-dose chemotherapy.The changes of peripheral blood counts of the mice were recorded.Results Approximately(6～9)?10~9 MSCs from SLE were obtained after 5 passages and their growth was slower than normal controls(P＜0.01).Both groups were positive for CD29,CD44 and CD105,and negative for CD14,CD34,CD45 and HLA-DR.MSCs from SLE had a normal karyotype.MSCs infusions of the two groups were accompanied by no adverse event and the recovery of white blood cell,hemoglobin and platelet count was quicker when compared with the controls(P＜0.05).Conclusion MSCs from SLE have demonstrated abnormalities in expansion in vitro.MSCs from SLE have a normal karyotype.Ex vivo MSCs infusion from SLE patients can support hematopoiesis as normal MSCs.

Purpose:To study the activity of toremifene and its synergistic effect with anti-tumor drugs on human lung adenocarcinoma cell line A549,which might be expected to provide a new mode of therapy for the clinical management of lung cancer.Methods:The cytotoxic effects of these agents on human lung cancer cell line A549 were measured by a tet- razolium-based volorimetric assay (MTT assay).Results:Toremifene can inhibit the growth of A549 cell directly.The A value of the low dose toremifene combined with anti-tumor drugs were lower than that of anti-tumor drugs alone.Toremifene combined with VCR,ADM,DDP and VP-16 showed better effects.Conclusions:Toremifene combined with chemotherapy drugs shows significant synergistic anti-tumor effect on A549 cell.This might provide experimental evidence for lung cancer therapy.

Objective To investigate the relationship between cross‐sectional area (CSA) and average CT value of posterior vertebral extensor group and bone mineral density(BMD) in postmenopausal women .Methods Totally 114 postmenopausal women being eligible for inclusion were enrolled .All the subjects ,ages range from 55 to 87 years old ,underwent quantitative computed tomography(QCT) scans from December 2015 to December 2016 in Beijing Jishuitan Hospital .The original image was transmitted to the image postprocessing workstation ,using Mindways QCT Pro software ,vertebral bone mineral density of L2-L4 were meas‐ured .CSA and average CT value of bilateral posterior vertebral muscles were measured by 2 diagnostic physicians in the L4 verte‐bral body horizontal axis CT images ,and analyzed respectively .Results Average CT values of posterior vertebral muscles between the left and the right side had a significant difference (P<0 .01) .The average CT value of bilateral posterior vertebral muscles was positively correlated with lumbar bone mineral density measured by QCT(P<0 .01) .There was no significant correlation between the CSA of posterior vertebral extensor group and BMD .Conclusion The loss of posterior vertebral muscle mass may be an impor‐tant risk factor for osteoporosis .The average CT value of posterior vertebral extensor group is more promising than CSA in the e‐valuation of the degenerative muscles .
