Objective To develop a optimized rehabilitation protocol for acupuncture, Tuina and ultrasonic treatments of upper limb motor dysfunction after cerebral infarction.Methods An orthogonal design with three factors (acupuncture as factor A, Tuina as factor B and ultrasound as factor C) and two levels was used. Eighty cerebral infarction patients with upper limb motor dysfunction were randomly allocated to eight groups, 10 cases each. The National Institute of Health Stroke Scale (NIHSS) score and the simplified Fugl-Meyer Assessment (FMA) score for upper limb motor function were recorded after four weeks of treatment. Results There were no statistically significant pre-treatment differences in the NIHSS score and the FMA score for the upper limb between the groups (P>0.05). For an improvement in NIHSS, factors A and B were both significant (bothP<0.05); there was no statistically significant difference in factor C between the two levels (P>0.05). Factors A, B and C were all significant for an improvement in the FMA score for the upper limb (P<0.05,P<0.01,P<0.05). A2B1C1 was the optimal protocol.Conclusions A combination of bilateral acupuncture, Tuina and ultrasound is an optimized protocol for treating upper limb motor dysfunction after cerebral infarction. It can effectively reduce upper limb motor dysfunction.

Objective To observe the curative effect of pricking bloodletting combined with acupuncture on patients with piriformis injury syndrome.Methods A prospective randomized controlled clinical trial was conducted, 84 patients with piriformis injury syndrome admitted to the Department of Acupuncture and Massage in the First Affiliated Hospital of Xinjiang Medical University from May 2011 to May 2014 were enrolled, and they were divided into observation group and control group by random number table, each group being 42 cases. The patients in the observation group were treated with bloodletting once a week (after bloodletting no other treatment was given), and then once a day of acupuncture was performed for 4 days in a week, completing one therapeutic course; while in the control group, the patient was treated with routine acupuncture once a day for 5 days in a week, finishing one therapeutic course. The interval between two therapeutic courses was 2 days, two courses were carried out, and afterwards the clinical therapeutic effects were evaluated in the two groups. The changes of visual analogue scale (VAS) of two groups before and after treatment and the therapeutic effects were observed.Results The VAS score of the two groups after treatment was lower than that before treatment, and the degree of decrease of VAS score in the observation group was significantly lower than that of thecontrol group (1.50±1.35 vs. 2.69±1.68,P < 0.01); the total effective rate in the observation group was obviously higher than that in the control group [100.00% (42/42) vs. 69.05% (29/42),P < 0.01].Conclusion Pricking bloodletting combined with acupuncture therapy for treatment of piriformis injury syndrome can shorten the course of treatment.

Objective: To investigate the effects of Radix Ginseng and Radix Notoginseng formula on secretion of vascular endothelial growth factor (VEGF) and expression of vascular endothelial growth factor receptor-2 (VEGFR-2) in human umbilical vein endothelial cells (HUVECs) in vitro. Methods: HUVECs were cultured in vitro. Bovine basic fibroblast growth factor (bFGF) at concentration of 320 U/mL and Radix Ginseng and Radix Notoginseng formula at concentrations of 0.1, 0.2 and 0.4 mg/mL were used to culture with HUVECs. And HUVECs in blank control group were cultured with culture solution only. After 24-hour culture, the content of VEGF in supernatant was detected by enzyme-linked immunosorbent assay and the expression of VEGFR-2 was detected by immunocytochemical staining and Western-blotting. Results: Radix Ginseng and Radix Notoginseng formula at 0.4 mg/mL, the same as bFGF, increased VEGF content in the HUVEC supernatant and the number of VEGFR-2-positive HUVECs. Expression of VEGFR-2 protein in high-dose Radix Ginseng and Radix Notoginseng formula group was up-regulated as compared with the blank control group. Conclusion: Radix Ginseng and Radix Notoginseng formula can promote HUVEC proliferation and secretion of VEGF, as well as the expression of VEGFR-2 protein, which may be one of the mechanisms of Radix Ginseng and Radix Notoginseng formula in promoting angiogenesis.

Objective To isolate and identify the putative Japanese encephalitis virus (JEV) re-ceptors from C6/36 and Vero cells. Methods Molecules binding with JEV were isolated from C6/36 and Vero cells by co-immunoprecipitation (Co-IP) approach, identified by mass spectrometry, and detected by Western blot. The location of putative JEV receptor on cells membrane and the binding with JEV were ob-served by laser scanning confocal microscopy (LCM). Results Several molecules binding with JEV were isolated from C6/36 and Vero cells by Co-IP, and only one molecule was identified as heat shock cognate 70 (HSC70) by mass spectrometry. Antibody against HSC'70 was able to detect a 74 ×103 protein isolated by Co-IP from C6/36 and Vero cells membrane in Western blot assays. It was observed by LSCM that when JEV attached on the surface of C6/36 cells, JEV and HSCT0 protein were co-localization. Conclusion 74 x 103 molecular identified as HSC70 protein from C6/36 cells may be JEV receptor.

Objective To explore the screening of peroxisome pathway reactive oxygen species (ROS) oxidative stress gene and its correlation with the antitumor sensitivity of artesunate against pancreatic cancer. Methods Based on microarray mRNA expressions of 55 tumor cell lines in the National Cancer Institute common database,peroxisome pathway-related key genes which were significant correlation with half-inhibitory concentration (IC50 )values of artesunate antitumor activity against human pancreatic cancer were selected by Kendall test.The candidate genes associated with artesunate sensitivity were identified and their mRNA expressions in pancreatic cancer cells were tested using fluorescent quantitative PCR.The contents of peroxi-dase in pancreatic cancer cells were detected through the DAB staining.Results Thirteen key genes mRNA expressions in peroxidase pathways were significantly correlated with IC50 values for artesunate antitumor activi-ty.Compared with normal liver cells HL-7702 (1.00),CRAT (2.89 ±0.06),PEX11B (1.90 ±0.07)and PEX16 (1.35 ±0.07)mRNA expression levels were significantly increased in pancreatic cancer Panc-1 cells which sensitive to artesunate (t =33.00,P <0.01;t =17.85,P <0.01;t =4.54,P <0.05).While CAT
(1.43 ±0.03),SOD1 (2.07 ±0.04)and SOD2 (1.15 ±0.01)mRNA expression levels were also signifi-cantly increased in Panc-1 cells which sensitive to artesunate (t =11.71,P <0.01;t =35.85,P <0.01;t =13.22,P <0.01).However,PEX12 (0.51 ±0.02),CAT (0.47 ±0.02),PRDX1 (0.43 ±0.01),and SOD1 (0.44 ±0.01)mRNA expression levels in pancreatic cancer BXPC-3 cells which resistant to artesunate were significantly lower than that of HL-7702 cells (t =37.53,P <0.01;t =16.52,P <0.01;t =84.20, P <0.01;t =48.24,P <0.01).DAB staining showed that the positive expression rate of peroxisomal content was apparently higher in Panc-1 cells (61.5%)than that of HL-7702 cells (43.8%),with a significant difference (χ2 =16.11,P <0.01).Conclusion Peroxisome and its related ROS antioxidant enzymes CAT, PRDX1,SOD gene expression may be the important factors that affect artesunate antitumor activity against human pancreatic cancer.
