Objective The effectiveness of Zhuang nationality medical lotus needle plus back cupping therapy ( Zhuang needle-cupping therapy) , Flixonase aqueous nasal spray and cetirizine tablets in treating allergic rhinitis (AR) was compared for the exploration of the therapeutic mechanism of Zhuang needle-cupping therapy. Methods A total of 200 recruited AR patients were randomly divided into four groups in the proportion of 1:1:1:1. The four groups were Zhuang needle-cupping therapy group, cetirizine group, Flixonase group and blank control group. The blank control group had no medication, and the patients of the other three medication groups were given the corresponding treatment. Ten days constituted one treatment course, and interval between two courses lasted one week. After two courses, the therapeutic effect was evaluated. The changes of specific IgE (S-IgE), leukotriene (LT), interleukin 4(IL-4), IL-9 mRNA, interferon gamma (IFN-γ), Thl / Th2 cells, and Th17 cytokine ( IL-17) were observed before and after treatment. Results ( 1) After two treatment courses, Zhuang needle-cupping therapy group had better therapeutic effect than cetirizine group , Flixonase group and blank control group, and the therapeutic effect of cetirizine group and Flixonase group was better than the blank control group (P<0.05). However, the therapeutic effect of cetirizine group was similar to that of Flixonase group ( P>0.05). ( 2) After treatment, the levels of S-IgE, LT, IL-9 mRNA, IL-4 and IL-17 were decreased, and IFN-γ and Th1/Th2 levels were increased in the three medication groups ( P<0.05 compared with those before treatment) . The differ ences of the laboratory indexes in the blank control group were insignificant before and after treatment ( P>0.05). The results of inter-group comparison after treatment showed that Zhuang needle-cupping therapy group had better effect on improving S-IgE, LT, IFN-γand Th1/Th2 than cetirizine group and Flixonase group (P<0.05). (3) During the trial, no adverse reaction was found. Conclusion Zhuang needle-cupping therapy exerts certain therapeutic effect for AR, and the mechanism may be related with the inhibition of S-IgE, LT, IL-9 mRNA and IL-17 expression, and with the regulation of Th1/Th2 imbalance by decreasing TH2 cytokine level and increasing Th1 cytokine level.

Objective To examine the effect of simvastatin treatment on Parkinson's disease rats induced by lipopolysaccharide (LPS) and its mechanism.Methods The LPS-PD model was established by injection of LPS (5 mg/mL) into the right substantia nigra compacta (SNC),and rats were randomly divided into control group,LPS-model group and simvastatin treatment group with 15 rats in each group.Rats in the simvastatin treatment group was intraperitoneally administered simvastatin (5 mg/kg) before,and daily for 14 days after surgery,while the control group and LPS-model group received same volume normal saline and LPS respectively.Ionized calcium binding adaptor molecule 1 (Iba-1)-positive cells and the expression of tyrosine hydroxylase (TH),tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) in the SNC were detected by immunohistochemistry,Western blotting and enzyme-linked immunosorbent assay,respectively.The effect of simvastatin in the PD model was also examined in behavioral tests.Results The LPS-model group exhibited typical animal PD behaviors.Compared with the control group,the LPS-model group exhibited a decreased number of DA neurons,and comparison of the intact side to reduce 81.13％ (P＜0.01) in the SNC,as well as increases in the Iba-1-positive cell number,iNOS,IL-1β and TNF-α expression (P＜0.05).These effects were inhibited by simvastatin treatment (P＜0.05).Conclusion Simvastatin mediates a protective effect on dopaminergic neurons in the SNC in the LPS-PD model,possibly by inhibiting glial cells (astrocytes and microglia) activation,and playing an anti-inflammatory role,thus improving substantia nigra function.

Objective To establish a RP-HPLC method for determining indigo and indirubin in Baphicacanthus cusia from different producing areas and medicinal parts. Methods The separation was achieved by an Agilent TC-C18 Column (4.6 mm×250 mm, 5 μm) at 25 ℃ using methanol-water (75??25) as mobile phase at a flow rate of 1 mL??min-1.The detection wavelength was 290 nm. Results Indigo had a good linear relationship with peak area at range of 0. 051 3-0.820 8 μg (r=0.999 3).The recovery rate was 99.00% and RSD was 1.30% (n=6).Indirubin had a good linear relationship with peak area at range of 0.049 5-0.792 0 μg (r=0.999 9).The recovery rate was 98.88% and RSD was 1.51% (n=6). Conclusion The contents of the two components are obviously different in Baphicacanthus cusia because of different places or medicinal parts. The proposed method is simple, rapid and reliable. This method for determination of indigo and indirubin in Baphicacanthus cusia by RP-HPLC provides a basis for quality control of Baphicacanthus cusia.

Objective:To investigate the effects of epidural spinal cord stimulation (ESCS) and treadmill training on the locomotion function and ultrastructure of spinal cord anterior horn after moderate spinal cord injury in rats. (IT, n=3). All rats received a moderate spinal cord injury surgery. Four weeks after surgery, rats in SE group received an electrode implantation procedure, with the electrode field covering spinal cord segments L2-S1. Four weeks after electrode implantation, rats received subthreshold ESCS for 30 min/d. Rats in TY group received 4cm/s treadmill training for 30min/d. Rats in SI group received no intervention, as a control group. All procedures in these three groups lasted four weeks.The open field Basso,Beattie and Bresnahan (BBB) scale was used before and after intervention to evaluate rats' hindlimb motor function. Result:After four weeks intervention, rats in TT group improved their open field locomotion scores to 20. In contrast, no significant improvement was observed in groups SI and SE. The morphology of synapses and neurons were similar regardless of whether rats had undergone ESCS, treadmill training or not. Conclusion:ESCS alone was not sufficient to improve the walking ability of spinal cord injured rats. ESCS or treadmill training alone might not contribute to the changes of ultrastructure in anterior horn of spinal cord that underlie the recovery of walking ability. Further research is needed to understand the contributions of combination of ESCS and treadmill training to the rehabilitation of spinal cord injured rats.

Objective To investigate the relationship between serum transforming growth factor- β1(TGF- β1) levels and early diabetic nephropathy and clarify whether valsartan plays a role in renal protection by reducing the level of serum TGF-β1. Methods The study subjects were divided into four groups:control group (30 cases); normal albuminuria group 1 (NA1 group with 12 cases, U MA/Cr < 10 μg/mg combined with type 2 diabetes);normal albuminuria group 2 (NA2 group with 19 cases,UMA/Cr 10-30 μg/mg combined with type 2 diabetes); microalbuminuria group ( MA group with 35 cases, U MA/Cr 31-300 μg/mg combined with type 2 diabetes). All these type 2 diabetic patients were suffering from diabetic retinopathy, and valsartan ( 80 mg/d) were medicated for those combined with hypertension. The serum TGF-β1 levels were measured by enzyme-linked immunosorbent assay in all subjects. Results Serum TGF- β1 levels in three diabetes groups were (7.41 ± 2.68 ), ( 10.52 ± 4.10), (22.98 ± 43.74) ng/L, respectively, all of which were higher than those in control group [(4.25 ± 5.82) ng/L] (P < 0.05). There were significant differences in serum TGF- β1 levels among MA group, NA2 group and NA1 group (P < 0.05 ). Serum TGF-β1 levels in NA1 group with valsartan treatment significantly decreased compared with those without valsartan treatment (P < 0.05), whereas there was no significant reduction in NA2 and MA group with valsartan treatment (P > 0.05). Conclusions High serum TGF-β1 level may be associated with type 2 diabetes and early diabetic nephropathy. Early intervention of valsartan may be delay the onset and development of diabetic nephropathy by decreasing the serum TGF-β1 level.
