Objective To discover the treatment rules of rhinitis and its complications with or without Chinese and Western drugs using the text mining technology. Methods The treatment rules of rhinitis and its complication were discovered using Chinese text words, data cleaning, word frequency and correlation analysis respectively with CNKI-covered papers and doctors-patients interactive forum data as the sources. Results The rhinitis received Western drug therapy, traditional Chinese medicine therapy, traditional Chinese medicine preparation therapy and non-drug therapy respectively . Xanthium was often used as a folk prescription for rhinitis, Jade Screen Powder was used as an important traditional Chinese medicine reparation for rhinitis, acu-puncture and massage were used as non-drug therapies for rhinitis, immune therapy and desensitization therapy were recommended, normal saline was usually used as an adju-vant therapy. Combined traditional Chinese medicine and Western drug therapy was advised at present. The incidence of nasosinusitis was the highest, followed by that of trachi-tis, pharyngitis, tympanitis, pneumonia, etc. Their symp-toms were different and were thus treated with different drugs. Conclusion The treatment rules of rhinitis and its complication can provide reference for drug selection and basic research, verify the usability of medical network da-ta and the feasibility of text mining.

OBJECTIVETo study the effect of sour TCM compound Recipe (SCCR) on insulin resistance in experimental rats with diabetes mellitus type 2 (DM2), under the guidance of TCM doctrine of "sour restrains sweet".

METHODSModel rats of DM2 were established by 8 weeks' feeding with high calorie forage combined with intraperitoneal injection of small dose of streptozotocin, and treated with SCCR (15 g/kg of crude drug/day). Levels of fasting blood glucose (FBG), serum insulin, free fatty acids (FFA), tumor necrosis factor a (TNF-alpha), combining capacity and constant of insulin receptor in liver were determined before treatment and 4, 8 and 12 weeks after treatment, and the insulin sensitive index was calculated. The data were compared with those in the model group (untreated), sweet TCM compound recipe group and bitter TCM compound group (treated with sweet and bitter Chinese drugs respectively) and the control group (treated with dimethyldiguanide).

RESULTSSCCR could markedly reduce the FBG, serum FFA and TNF-alpha levels in rat model of DM2, stimulate the secretion of insulin, raise the combining capacity and constant of insulin receptor in liver and improve the insulin sensitivity, as compared with the effect of sweet or bitter Chinese compound recipe, the difference was significant (P < 0.05).

CONCLUSIONSCCR could improve the glucose metabolic disorder and ameliorate the degree of insulin resistance in DM2 model rats, with the effect superior to those with sweet or bitter taste, which illustrates primarily that the therapeutic principle of "sour restrains sweet" of TCM is true of science in a certain degree and having its guiding significance in clinical practice.

OBJECTIVETo evaluate the effect of Qufeng Zhidong Recipe (QZR) on the head tic behavior, and the mRNA expressions of Notch1 and dopamine D2 receptor (D2R) in tic disordered mice.

METHODSMouse model like wet-dog shake head tic disorder was established by peritoneal injection of 5-HT2A/C agonist DOI for 14 successive days. The model mice were divided into three groups, the model group, the Chinese medicine (CM) treated group and the Western medicine (WM) treated group, they were intervened respectively with distilled water, QZR (10 g/kg) and haloperidol (1 mg/kg). Besides, a normal control group was set up and gastrogavaged with distilled water. The effect of intervention was evaluated 2 weeks later by estimating the head tic and the creeping distance of animals, and the mRNA expressions of D2R and Notch1 in corpus striatum and prefrontal cortex regions were detected using Real-time PCR.

RESULTSThe wet-dog shake response and the creeping distance of mice were significantly reduced after intervention in both intervened groups, showing insignificant difference between the effects of CM and WM (P > 0.05). The expression of D2R mRNA in corpus striatum was higher than that in the prefrontal cortex (P < 0.01), at the prefrontal cortex, it was 151 +/- 30 in the CM group and 180 +/- 41 in the WM group, and at the corpus striatum, 710 +/- 64 and 850 +/- 80 respectively, all higher than those in the model group (P < 0.05). While the Notch1 mRNA expression in model mice were lower at the prefrontal cortex than at the corpus striatum (P < 0.05). After intervention it was 55 +/- 20 in the CM group and 48 +/- 23 in the WM group at the prefrontal cortex, all significantly lower than that in the model group (P < 0.05).

CONCLUSIONDOI-induced wet-dog shake response could well simulate the clinical characteristics of tic disorder; QZR could improve the tic behavior and creeping distance in the model mice. The up-regulation of D2R mRNA expression after QZR intervention may be related with the down-regulation of Notch1 expression, this findings is worthy of further studies.

This study discusses the effects of Shenlian extracts (SL) on M1 macrophages in atherosclerosis. The MTT assay was used to detect the growth inhibition rates of RAW264.7 cells. RAW264.7 cells were stimulated with murine interferon-gamma (IFN-gamma) plus lipopolysaccharide (LPS) to induce M1 macrophages. The different concentrations of SL extracts (high-dose 50 mg x L(-1), moderate-dose 25 mg x L(-1), low-dose 12.5 mg x L(-1)) were added. The CD86 of M1 macrophages in cell membrane was measured by flow cytometry. The mRNA expression of iNOS and TNF-alpha gene was detected by reverse transcription PCR (RT-PCR). And the supernatants were collected, the content of IL-6 and TNF-alpha were detected with ELISA kits. The results of this experiment show that the expression of the cell membrane molecule CD86, iNOS and TNF-alpha gene, the content of IL-6 and TNF-alpha was obviously increased in M1 macrophages by IFN-gamma and LPS. The different doses of SL extract could reduce the expression of the above indicators. The above experimental results demonstrate that IFN-gamma combined LPS can induce RAW264.7 cell to type into M1 macrophages, and SL extracts can inhibit M1 macrophages.

Abstract?AlM: To observe the effects of Shuangdanmingmu capsule on VEGF expression and retinal vascular morphology in rats with diabetic retinopathy ( DR) .?METHODS: DR rats were fed with Shuangdanmingmu capsule. By comparing with the normal group, the model control group, and positive control group, the effect of Shuangdanmingmu capsule on retinal tissue of DR rats was observed under electron microscopy. After HE staining, retinal structure was observed under the light microscope. lmmunohitochemical staining was used to detect the VEGF expression in retina.?RESULTS:Two months after treatment, the layers tissue of retina presented mild edema, capillary pericytes performed edema, mitochondria showed mild swelling and less clear structure, some endothelial cells showed slight proliferation in Shuangdanmingmu group. Compared with the normal group, the expression level of VEGF in retina increased in the other groups, especially in model control group. A significant differential in expression of VEGF was found between Shuangdanmingmu group, positive control group and model control group (P<0. 01).? CONCLUSlON: Shuangdanmingmu capsule can effectively improve the retinal microvascular, reduce edema and necrosis of each layer of retina, improve the ultrastructure of retina's tissue and inhibit VEGF expression in DR rats.
