OBJECTIVETo observe the effects of electroacupuncture at Neiguan (PC 6) and Jianshi (PC 5) com- bined with granisetron on nausea and vomiting as well as serum levels of 5-hydroxy tryptamine (5-HT) and dopamine (DA) in chemotherapy patients.

METHODSSeventy-two chemotherapy patients who met the inclusive criteria were randomly divided into an observation group (38 cases) and a control group (34 cases). The patients in the observation group were treated with electroacupuncture at Neiguan (PC 6) and Jianshi (PC 5) combined with granisetron injection; the patients in the control group were treated with electroacupuncture at sham-point 1 and sham- point 2, and the rest treatment was identical to the observation group. After 3-day treatment, the clinical indices including times of vomiting and severity of nausea, etc. were observed in the two groups.

RESULTS(1) At the acute stage within 24 h, the times of vomiting in the two groups were not significantly different (P>0.05); at the delay stage, the severity of nausea was significantly higher in the control group (P<0.05). (2) As for the comprehensive efficacy and rate of complete control, there was no obvious difference between the two groups at the acute stage (P>0.05); while in the delay stage, the rate of complete control in the observation group was superior to that in the control group (P<0.01). (3) Compared before and after the treatment, serum levels of 5-HT and DA were evidently reduced in the observation group (both P<0.05), while those in the control group were not significantly changed after treatment (both P>0.05).

CONCLUSIONElectroacupuncture at Neiguan (PC 6) and Jianshi (PC 5) combined with granisetron could obviously relieve the nausea in chemotherapy patients at the delay stage. The effect mechanism is possibly related to reducing the content of 5-HIT nndl nA

AIM: To examine the inhibition of matrix metalloproteinase (MMP) activity by doxycycline (Doxy) and its effect on vascular smooth muscle cells (SMCs) proliferation, neointimal hyperplasia and vascular remodeling. METHODS: The model of rat common carotid artery injury was established by balloon-dilatation. Doxy was administered to the animals of treatment group at dose of 30 mg?kg -1?d -1. The activity of MMPs in the tissue of injured carotid arteries was measured by gelatin zymography. The thickness and area of neointimal, lumen area and the proliferation of SMCs were measured by histological and morphometric analysis. RESULTS: 1. After Doxy treatment, the activity of MMP-9 in the carotid arteries was reduced by 26.3% and 34.5% compared to that in rats without Doxy treatment at 24 hours and 3 days after balloon injury, respectively (P

ObjectiveTo explore clinical effect and safety ofShaoyao-Gancao decoction combined withSiwu decoction for the patients with diabetic peripheral neuropathy (DPN).MethodsA total of 76 patients with DPN in our hospital from 2013 July to October 2015 were divided into control group and observation group by the random number method, 38 patients in each group. The control group were treated with conventional treatment combined with oryzanol injection, and the observation group were treated with Shaoyao-Gancaodecoction combined withSiwu decoction on the basis of control group. Both groups were treated for one month. The level of FPG, 2 hPG, HbAlc, TC, TG, LDL-C and HDL-C was detected respectively before and after treatment. The whole blood viscosity and plasma viscosity was detected with LBY-N6A self-cleaning rotary viscosimeter. The red blood cells deposited and platelet aggregation rate were tested with Winchester points vascular method and turbidimetric method, respectively.The leg nerve and sural nerve of nerve conduction velocity (nerve conduction velocity, NCV) were determined with electromyography, at the same time the clinical curative effect was evaluted.ResultsTotal effect rate of observation group was 89.5% (34/38), which was significantly higher than the control group 71.1% (27/38), and the difference was statistically significant (χ2=4.070,P=0.044); After treatment, the levels of FPG (6.12 ± 0.38 mmol/Lvs.6.58 ± 0.52 mmol/L, t=4.403), 2 hPG (7.83 ± 0.82 mmol/Lvs. 8.41 ± 0.93 mmol/L,t=2.884), HbAlc (6.27 ± 0.52%vs. 6.82 ± 0.64%, t=4.112) in the observation group were lower than those in the control group (P<0.05). The levels of TC (4.73 ± 0.83 mmol/L vs. 5.11 ± 0.64 mmol/L,t=52.235), TG (1.83 ± 0.35 mmol/Lvs. 2.03 ± 0.41 mmol/L, t=2.287) and LDL-C (2.91 ± 0.54 mmol/Lvs. 3.25 ± 0.58 mmol/L,t=2.645) in the observation group were lower than those in the control group (P<0.05), and the HDL-C (1.47 ± 0.33 mmol/Lvs. 1.26 ± 0.31 mmol/L,t=-2.859) in the observation group was higher than than that in the control group(P<0.05). The level of whole blood specific viscosity (10.16 ± 2.12 mPa?svs. 11.33 ± 2.51 mPa?s,t=2.195), plasma viscosity (1.24 ± 0.25 mPa?svs. 1.62 ± 0.37 mPa?s,t=5.246), red blood cell volume (0.31 ± 0.16L/Lvs. 0.42 ± 0.08 L/L,t=3.791) and platelet aggregation rate (50.21% ± 8.03%vs. 54.16% ± 7.82%,t=2.172) in the observation group were significantly lower than those in control group (P<0.05). The tibial nerve velocity (45.22 ± 3.20 m/svs. 38.26 ± 5.19 m/s,t=-7.037) and the common nerve velocity (43.22 ± 6.34 m/svs. 36.23 ± 4.81,t=-5.415) in the observation group were as significantly higher than those in control group (P<0.05).ConclusionsThe Shaoyao-Gancaodecoction combined withSiwu decoction could improve the state of blood sugar, blood lipid and blood rheology of patients with DPN, and improve nerve transfer speed of leg nerve and sural nerve, the curative effect is better than conventional western medicine therapy alone.

HIV-1 integrase (IN) is a key enzyme for the viral replication. The protein-protein interaction (PPI) between HIV-1 IN and a cellular cofactor lens epithelium-derived growth factor (LEDGF/p75) is a validated target for anti-HIV drug discovery. In order to build the platform for screening inhibitor against PPI between IN and LEDGF/p75, the vector containing the LEDGF/p75 protein cDNA was constructed and expressed in Escherichia coli and the function of the LEDGF/p75 protein was assayed. The LGDGF/p75 encoding gene optimized according to the preference codon usage of E. coli, was synthesized and cloned into the expression vector pGEX-4T-1 to form a recombined plasmid, then transformed into host cell E. coli BL21 (DE3). The recombined clones were identified and confirmed by BamH I/Sal I digestion and sequencing, the successfully recombined plasmid in the host cell was induced by IPTG and the condition of the expression was optimized. The expressed protein was purified by the Ni2+ affinity chromatography column and SDS-PAGE was used to analyze the molecular weight and specificity. In addition, ELISA assay was used to analyze the function of the recombinant protein. The recombinant LGDGF/p75 was soluble, and expressed highly and stably in E. coli. The protein was proved to enhance HIV-1 IN strand transfer activity in vitro by ELISA. It will be helpful to build the platform of screening inhibitors against PPI between IN and LEDGF/p75.
