Chinese Journal of Integrated Traditional and Western Medicine 2016;36(3):322-326
OBJECTIVETo explore the effect of electroacupuncture (EA) on the expression of Ghrelin and mRNA expression of its receptor in functional dyspepsia (FD) rats.
METHODSTotally 80 rats were divided into the normal group, the model group, the drug therapy group, and the EA group according to random digit table, 20 in each group. FD model was duplicated by clipping tail modeling. Drug containing cisapride [2 mL/100 g, 0.09 g/(kg x d)] was administered to rats in the drug therapy group from the 3rd day after successful modeling, once per day. EA at Zusanli (ST36) (0.3-0.5 cun) and Taichong (LR3) (0.1-0.2 cun) was performed in the EA group. The twirling of needle was performed to the subsidence of needle, and then the needle was connected to HANS-200A Acupoint Nerve Stimulating Device using disperse-dense wave at 2 Hz, 2 mA, 30 min each time, once per day. Six days consisted of one therapeutic course, two courses in total with an interval of one day. The intestinal propulsive rate of ink was observed. Ghrelin protein expression in gastric tissue was detected by Western blot. mRNA expression of growth hormone secretagogue receptor (GHS-R) in stomach, hypothalamus, and hippocampus was detected using Real-time PCR respectively.
RESULTSCompared with the normal group, the intestinal propulsive rate of ink, Ghrelin protein expression in gastric tissue, mRNA expression of GHS-R in stomach, hypothalamus, and hippocampus decreased in the model group (P < 0.05, P < 0.01). Compared with the model group, the intestinal propulsive rate of ink, Ghrelin protein expression in gastric tissue, mRNA expression of GHS-R in stomach, hypothalamus, and hippocampus increased in the EA group (P < 0.01); mRNA expression of GHS-R in stomach, hypothalamus, and hippocampus increased in the drug therapy group (P < 0.01). Compared with the drug therapy group, Ghrelin protein expression in gastric tissue, mRNA expression of GHS-R in hypothalamus increased in the EA group (P < 0.05, P < 0.01).
CONCLUSIONEA could regulate Ghrelin content and GHS-R mRNA expression of FD rat hypothalamus, hippocampus, and gastric tissue, and promote the intestinal propulsive rate of ink.

Objective To investigate the role of nucleotide-binding oligomerization domain-containing protein 1 (NOD1) in inducing insulin resistance in differentiated human adipocytes.Methods Human preadipocytes obtained via liposuction were induced to differentiate into mature adipocytes.iE-DAP,a specific ligand for NOD1,was administered to human adipocytes in culture.NF-κB transcriptional activity and proinflammatory cytokines production were determined by luciferase assay and enzyme-linked immunosorbent assay.Glucose uptake in adipocytes was measured by 2-deoxy-D-[3 H] glucose uptake (P<0.05).The expression of phosphatidylinositol-3-kinase p85 (PI-3K p85),insulin receptor substrate-1 (IRS-1) and Akt phosphorylations were detected by Western blotting.Results NF-κB transcriptional activity and cytokines such as interleukin (IL)-6,IL-8,and monocyte chemotactic protein 1 secretion were markedly increased after stimulation with iE-DAP (P<0.05 or P<0.01).Insulin-induced glucose uptake was decreased with the activation of NOD1 in a dose-and time-dependent fashion.NOD1 activation weakened insulin signal transduction as being revealed by increasing IRS-1 Ser307phosphorylation,reducing protein expression of PI-3K p85,and attenuating insulin-induced phosphorylation of Akt on Ser473 and Thr308in human adipocytes.Conclusion These results indicate that NOD1 activation induces inflammatory response and insulin resistance via IRS-1/PI3-K/Akt signaling pathway in human adipocytes.
7.Dapoxetine for premature ejaculation: Advances in clinical studies.
National Journal of Andrology 2015;21(10):931-936
Premature ejaculation (PE) is a most common sexual dysfunction, for which dapoxetine, a novel selective serotonin (5-HT) re-uptake inhibitor (SSRI), is the only licensed oral medicine at present. With the advantages of fast absorption, rapid action, on-demand medication, and short half-life time, dapoxetine has been proved by clinical trials to be effective in prolonging the intravaginal ejaculation latency time (IELT) and improving the overall condition of PE patients in various areas and populations. Compared with the traditional SSRIs, dapoxetine has a better safety and tolerability. The most frequently reported dapoxetine-related adverse events include nausea, diarrhea, headache and dizziness, but with very few severe or serious cases.

Objective: To study the nature and flavour of LIU Wan-su’ drug application and the tendency of cold or warm in his prescription; analyze LIU Wan-su’s medical sect by the index of prescription metrology. Methods: Combining the traditional documents with prescription metrology, selecting three doctors before or after LIU Wan-su in Jin and Yuan Dynasty as comparison to expose the characteristic of prescription metrology in his prescription. Results: Wen tonic frequency of each prescription on average, LI Dong-yuan(1.10),ZHU Dan-xi(0.97), LIU Wan-su (0.77), ZHANG Zi-he(0.65); Han tonic frequency of each prescription, LI Dong-yuan (1.34),ZHANG Zi-he (1.00), LIU Wan-su (0.94), ZHU Dan-xi(0.80);Cool and warm drug ratio of four sects in Jin and Yuan Dyanstay, ZHU Dan-xi (0.97),LI Dong-yuan(0.83), LIU Wan-su (0.82), ZHNAG Zi-he (0.58).Cool and warm prescription ratio, ZHANG Zi-he(1.50), LIU Wan-su (0.87), LI Dong-yuan(0.76), ZHU Dan-xi (0.50).Conclusion: As the exponent of "theory of fi re and hot", it will be better to classify LIU Wan-su as " Hejian sect" since his drug application was not limited within cold and cool. To some extent, it is more important to judge a Chinese traditional doctor by syndrome identifi cation rather than only by his drug frequency.
