OBJECTIVETo explore the curative effect and safety of acupuncture for mild cognitive disorders after stroke.

METHODSRandomized controlled trial was adopted and one hundred cases conforming to criteria were divided into a combined acupuncture and medication group (group A) and a medication group (group B), 50 cases in each group. The basic treatment of cerebrovascular disease was applied in two groups. The group A treated was with acupuncture at Baihui (GV 20), Shenting (GV 24) and Qucha (BL 4) etc. and oral administration of Nimodipine. In group B, Nimodipine was taken orally. The treatment lasted for 3 months, the scores of Mini-Mental State Examination (MMSE), modified Hasegawa Dementia Scale (HDS-R) and Barthel Index (BI) were observed before and after treatment in two groups.

RESULTSThe total effective rate in group A was 66.7% (32/48), which was superior to 30.4% (14/46) in group B (P < 0.05). The scores of MMSE, HDS-R and BI after treatment were apparently improved as compared with those before treatment in two groups (all P < 0.01). The improvements in group A were superior to those in group B (all P < 0.05). There was no adverse event reported during the treatment in two groups.

CONCLUSIONAcupuncture can improve activity of daily living and has significant effect in treating mild cognition disorders after stroke without adverse reactions.

OBJECTIVETo discuss the relative association of soft tissue tension and cervical physiological curvature chang in patients with scapula muscle fasciitis.

METHODSFrom February 2012 to December 2012,29 patients with scapula muscle fasciitis were investigated. There were 10 males and 19 females with an average age of 27.77 years old (ranged from 22 to 40 years old). Routine AP and lateral cervical X-rays were done in all patients. Cervical lordosis was measured according to Borden's method and the pain point tension was measured by soft tissue tension meter. Finally,perform statistic analysis to bove data.

RESULTSLateral X-rays showed 9 cases were normal cervical lordosis, 18 cases were cervical lordosis decreased, 2 cases were cervical lordosis increased. The regression equation of cerical lordosis changes D(Y) and soft tissue tension displacement D0.5 kg (X) was Y = -15.069 + 3.673X.

CONCLUSIONThere is linear relationship between soft tissue tension and cervical physiological curvature change. With the soft tissue tension increases, the cervical lordosis trend to decrease.

OBJECTIVETo explore the intervention of baicalin on signal transduction and activating transcription factor expression of ulcerative colitis (UC) patients.

METHODSRecruited were UC patients at Outpatient Department of Digestive Disease, Inpatient Department of Digestive Disease, Center for Digestive Endoscopy of College City Branch, Guangdong Provincial Hospital of Traditional Chinese Medicine, and Southern Hospital affiliated to Southern Medical University from June 2010 to January 2011. They were assigned to the UC group (33 cases) and the diarrhea-predominant irritable bowel syndrome (IBS-D) group (30 cases). Another 30 healthy subjects were recruited as a healthy control group. Peripheral blood mononuclear cells (PBMCs) in vitro intervened by different concentrations baicalin were taken from UC patients. IL23R gene expressions in vitro intervened by different concentrations baicalin were detected using Q-PCR. Expressions of signal transducer and activator of transcription 4 (STAT4) , STAT6, phosphorylated-STAT4 (p-STAT4), and p-STAT6 were detected using Western blot. Serum levels of IFN-γ, IL-4, IL-6, and IL-10 were measured by ELISA. Effects of different concentrations baicalin on expressions of PBMCs, and levels of IFN-γ, IL-4, IL-10 of UC patients were also detected.

RESULTSCompared with the negative control group, 40 µmol baicalin obviously decreased IL23R gene expression of UC patients (P <0. 01). Compared with the healthy control group and the IBS-D group, p-STAT4/STAT4 ratios increased, p-STAT6/STAT6 ratios decreased, levels of IFN-γ, IL-4, IL-10 all increased in the US group (all P <0. 05). Compared with the negative control, 5 and 10 µmol baicalin groups, 20 and 40 moL baicalin obviously decreased p-STAT4/STAT4 ratios (all P <0. 05); 20 and 40 µmoL baicalin obviously increased p-STAT6/STAT6 ratios (all P <0. 05); 20 and 40 µmoL baicalin obviously lowered levels of IFN-γ and IL-4, and elevated IL-10 levels (all P <0. 05).

CONCLUSION40 µmoL baicalin could in vitro inhibit p-STAT4/STAT4 ratios, adjust p-STAT6/STAT6 ratios and related cytokines, thereby balancing the immunity and relieving inflammatory reactions of UC.
