ABSTRACT
Background: Inflammatory bowel disease (IBD) is a chronic idiopathic gastrointestinal dis-ease, including ulcerative colitis (UC) and Crohns disease (CD), which is typically charac-terized by chronicity and relapse. Cinnamtannin D1 (CTD1), extracted from Cinnamomum tamala, has been found to exert good immunosuppressive activity. However, the role of CTD1 in IBD is unclear. Methods: The colitis mice model was established by dextran sulfate sodium (DSS) treat-ment. Protein levels (p-STAT3/STAT3, ROR-γt, p-STAT5/STAT5, FOXP3, p-AMPK/AMPK, and p-mTOR/mTOR) were examined using Western blotting analysis. Changes in histopathol-ogy were detected through hematoxylin and eosin staining. The proportion of T helper 17 (Th17) cells and regulatory T (Treg) cells was measured by flow cytometry analysis.Results: CTD1 improved body weight and colon length, and alleviated inflammation and histological damage in DSS-induced colitis mice model. DSS treatment also demonstrated a negative effect on Th17Treg cells balance whereas CTD1 restored the balance of Th17Treg cells in DSS-induced colitis mice model. Regulatory factors (such as STAT3, ROR-γt, STAT5, and FOXP3) that closely related to the balance of Th17Treg cells were regulated by CTD1. In addition, AMPK phosphorylation was increased and mTOR phosphorylation was inhibited by CTD1 in DSS-induced colitis mice model. Conclusion: These findings established that CTD1 improved DSS-induced colitis by suppress-ing Th17Treg cells balance by activating the AMPK/mTOR pathway. This study provided a new strategy for developing novel treatments for patients with IBD (AU)

Objective To observe the clinical efficacy of scalp cluster needling plus acupuncture at Conception Vessel points in treating generalized anxiety disorder.Method Sixty eligible subjects were divided into a treatment group and a control group by the random number table, 30 cases each. The treatment group was intervened by scalp cluster needling plus acupuncture at Conception Vessel points including Tiantu (CV22), Danzhong (CV17), Zhongwan (CV12) and Xiawan (CV10); in the control group, Shenmen (HT7), Daling (PC7), Neiguan (PC6), Qimen (LR14), Xinshu (BL15), Hegu (LI4) and Taichong (LR3) were selected. The treatments were given once a day, 6 sessions followed by 1-day interval as a treatment course, for successive 8 courses in total. The Hamilton Anxiety Scale (HAMA) scores of the two groups were compared before and after the treatment and in the follow-up study; the clinical efficacies were also compared.Result The treatment protocols in the two groups were both effective in treating generalized anxiety disorder, while the markedly effective rate was significantly higher in the treatment group than in the control group (P<0.05). The HAMA scores after treatment and in the 1-month follow-up study were significantly different from the score before the treatment in both groups (P<0.01). There were significant differences in comparing the HAMA score between the two groups respectively after treatment and in the 1-month follow-up study (P<0.05). Conclusion Scalp cluster needling plus acupuncture at Conception Vessel points shows significant advantage in treating generalized anxiety disorder compared to the ordinary acupuncture method.

ABSTRACT
Background Researches showed that wild-type p53(wtp53)and Rb94 genes inhibit the growth of retinoblastoma(RB),and these genes are involved in signal pathway in the induction and maintenance of cellular senescence.Thus the combination of two genes to inhibit growth of RB is concerned.Objective This study was to observe the inhibitory effect of the co-transfection of Rb94 and wtp53 gcnc into subretina on RB with ultrasound microbubble.Methods HXO-Rb44 suspension was subretinally injected to establish the RB model in 40 SPF female Balb/c nude mice.The RB models were randomized into model control group,wtp53 group,Rb94 group and wtp53+Rb94 group,and 0.1 ml relevant gene microvesicle suspension was injected via caudal vein in the different groups,but no any gene was used in the model control group.Seven days after modeling,followed by 0.5 W/cm2ultrasonic wave irradiated the eyeballs immediately for 4 seconds ×2 times and interrupted for 24 seconds.Eyeballs were extracted 7 days after gene transfection,and the expressions of wtp53 mRNA and Rb94 mRNA in tumor tissuc were detected by RT-PCR,and wtp53 and Rb94 protein in tumor tissue were assayed using Western blot.Immunochemistry was used to exam the VEGF expression,and TUNEL was used to evaluate the apoptosis of the tumor cells.Results The model successful rate after HXO-Rb44 suspension was 80％ (32/40)and obvious malformation cells were seen under the light microscope.In 7 days after gene transfection,no response band for wtp53 mRNA and Rb94 mRNA were found.The relative expression valuc of wtp53 mRNA was 0.65±0.07 in the wtp53 group,and that in wtp53+Rb94 group was 0.32±0.02,showing a significant difference between them (t =11.743,P =0.000).Rb94mRNA relative value was 0.42 ±0.03 in Rb94 group,and that in the wtp53 + Rb94 group was 0.23 ± 0.03,with a significant difference(t=5.041,P=0.001).The response bands of wtp53 and Rb94 proteins were seen in wtp53group,Rb94 group and wtp53+Rb94 group.Immunochemistry showed that the positive reactive intensity for VEGF in tumor tissue was obviously weaker in wtp53+Rb94 group than that in the wtp53 group,Rb94 group and model control group.Apoptotic index(Al) was 37.35±2.14 in the wtp53+Rb94 group,showing a significant increase in comparison with model control group (0.46 ± 0.05),wtp53 group (5.05 ± 0.80) and Rb94 group (6.43 ± 1.02) (t =-34.395,-28.206,-26.006,P＜0.01).Conclusions Ultrasound microvesicle enable double gene transfecting into RB tumor tissue,and Rb94 gene cooperation with wtp53 gene enhance the inhibitory effect on RB by promoting the apoptosis of RB cells.
