Objective To observe the therapeutic effects and assess the feasibility of radiofrequency thermo- coagulation denervation(TRD)mediated by digital subtraction angiography(DSA)for patients with lumbar facet joint syndrome(LFJS).Methods Eighty LFJS patients were randomly divided into two groups:a denervated group(groupⅠ)and a control group (groupⅡ).The lumbar facet joints of the patients in groupⅠwere treated with TRD,while those in groupⅡhad their lumbar facet joint cavities injected with the mixture of 1 mg betamethasone and 1 ml lidocaine.All patients were assessed using the Visual Analog Scale(VAS)before treatment and 30 rain,1 d, 1 w,1 m and 6 m after.Schober values were measured at 1 w,1 m and 6 m after treatment.The therapeutic effects and side effects were assessed at 6 m after treatment.Results VAS scores in groupsⅠandⅡat 30 min,1 d,1 w and 1 m after treatment were remarkably lower than before treatment.In addition,those in groupⅠ6m after treatment were also significantly lower(P＜0.01).Compared with those in the groupⅡ,VAS scores in groupⅠwere signifi- cantly decreased at 1 m and 6 m after treatment(P＜0.05 and P＜0.01,respectively).The schober values in groupⅠat 1 m and 6m were obviously increased in comparison with those in groupⅡ,while the therapeutic effects in groupⅠat 6m after treatment were better than those in groupⅡ(P＜0.01).There were no side effects,such as injuries to the nerve roots or dysfunctional dermal sensation,in either group.Conclusion TRD,mediated by DSA,has ther- apeutic effects on LFJS.Such treatment is safe,convenient,and gives long-term pain relief.

Objective: To optimize the formula of memantine hydrochloride sustained release pellets and investigate the drug release in vitro.Methods: Memantine hydrochloride sustained release pellets were prepared by a fluidized bed.The factors such as inlet air temperature, spray pressure and feeding rate were optimized by orthogonal tests.The Box-Behnken response surface methodology was used to screen the major influencing factors (ethyl cellulose aqueous dispersion, PEG 6000 and the coating weight) in the release of memantine hydrochloride.The coating formula and coating weight were optimized with the cumulative release rate of memantine hydrochloride in 2, 6,and 12 h as the response values.The drug release in vitro was also studied.Results: The optimum preparation parameters of the pellets were as follows: the inlet air temperature of 45℃, the spray pressure of 1.0 bar, and the feeding rate of 1.5 r·min-1.The best sustained release coating formula was as follows: the content of ethyl cellulose aqueous dispersion of 8.4%, the content of PEG 6000 of 2.3%, and the weight gain of sustained release layer of 16.7%.The memantine hydrochloride sustained release pellets had notable sustained release effect.Conclusion: Orthogonal tests and Box-Behnken response surface method can be used for the formula optimization of memantine hydrochloride sustained-release pellets.The established fitting model is simple with good predictability.

AIM To study the targeted transfer and expression of human endothelial nitric oxide synthase gene-immunoliposome delivery system mediated by caveolin-1 antibody in hypercholesterolemic endothelial cells. METHODS Cultured ECV304 cells were divided into normal and hypercholesterolemic groups and transfected with control vector pcDNA3.1, cationic liposome-eNOS complex (lip-eNOS) or polylysine modified caveolin-1 antibody-cationic liposome-eNOS complex (Ab-lip-eNOS) respectively. The negative control group was also used. The experiments were made in triplicates. 48 h after transfection, the cellular eNOS mRNA was detected by RT-PCR, the eNOS activity assayed by NADPH-diaphorase staining and the generation of NO in medium determined by Griess method. RESULTS Ab-lip-eNOS and lip-eNOS could efficiently induce the expression of exogenous eNOS gene in endothelial cells cultured in normal or hypercholesterolemic condition, increase eNOS mRNA level, eNOS activity and NO content, which were significantly different from the endogenous eNOS gene expression of negative control and control vector groups (P
