Objective To evaluate the efficacy and safety of etoricoxib and meloxicam in the treatment of patients with acute gout. Methods A randomized,active comparator study was conducted at outpatients and inpatients in our hospital from January 2009 to July 2010.A total of 84patients aged (63.7± 11.0) years with an acute attack of gout were treated with etoricoxib 120 mg/d (n =48),or meloxicam 15 mg/d (n =36) for 7 d.The patient's assessment of joint pain (0- 4 point Likert scale) at drug treatment for 2-5 d was considered as the primary efficacy end point,4 h after firstly takiug the drug and 2-8 d after treatment as the secondary efficacy end point.The starting efficacy was determined until pain relieved by patient himself. The safety was assessed by adverse experiences and indexes including leucocyte, platelet,crcatinine, uric acid,alanine transaminase (ALT),aspartate transaminase (AST) and mean artery pressure(MAP). Results In 84 patients,3cases (8.3%) in meloxicam treatment and 15 cases (31.2%) in etoricoxib treatment (among which 13 cases finished treatment) discontinued therapy.The improvement scores of joint pain were (-0.41 ±0.35 vs.-0.19±0.30,P=0.005) at4 h after firstly taking the drug,(-1.66±0.58 vs. 1.38±0.44,P=0.018)at drug treatment for 2 -5 d,( - 1.83 ± 0.60 vs.- 1.85 ± 0.53,P=0.9) at 2 8 d after treatment,and (-2.64±0.45 vs. - 2.38±0.37,P=0.000) post-treatment higher than pre treatment.The starting time of pain relieving were (4.0 ± 4.6) h in etoricoxib treatment and (12.1±5.7) h in meloxicam treatment. The levels of leucocyte were decreased after treatment as compared with before treatment in both two drug treatments(P<0.05),while no differences were found in platelet.creatinine,uric acid,ALT and AST.MAP after etoricoxib treatment was increased compared with pretreatment ( P < 0.05 ). Drug related adverse experiences appeared in 15 cases (31.2 % ) in etoricoxib treatment and 12 cases(33.3 % ) in meloxicam treatment(P=1.000).The ratio of gastrointestinal tract-related adverse effects in meloxicam treatment was higher than in etoricoxib (22.2% vs.6.2%,P< 0.05),while adverse effects on cardiovascular in etoricoxib treatment were comparable to that of meloxicam (16.7 % and 11.1 %,P>0.05). Conclusions Etoricoxib at a dose of 120 mg once daily may be more effective than meloxicam for acute gout in aspects of safety and tolerance.

China Biotechnology 2006;0(12):-
"CapFinder" technology,which can be used to clone the full length of 5′ UTR sequence of mRNA,was described.This technology used the terminal transferase activity of certain MMLV RT variants that added 3-5 residues(predominantly dC) to the 3′end of the first-strand cDNA exhibited when MMLV RT reached the 5′cap structure of mRNA.In the reverse reaction system containing GGG oligo,the terminal transferase activity was harnessed by the GGG oligo whose terminal stretch of dG residues can anneal to the dC-rich cDNA tail and serve as an extended template for RT.After RT switch templates from the mRNA template to the GGG oligo,a complete cDNA copy of the original RNA was synthesized with the additional GGG oligo sequences at the end.5′UTR of mRNA can be amplified with GGG oligo as forward primer and a gene-specific reverse primer.5′UTR of Bt toxin receptor E-Cadherin gene in midgut of cotton bollworm was cloned.

Chinese Journal of Geriatrics 2000;0(04):-
Objective To determine the efficacy and safety of acarbose in the treatment of senile postprandial hypotension (PPH). Methods Forty three senile in-patients with PPH were recruited. Blood pressure and heart rate(HR) were recorded for 120 minutes by using non-invasive ambulatory blood pressure monitoring system. The participants had semiliquid standard meals with or without acarbose on two following days. The ejection fraction(EF) and fractional shortening(FS) were measured by two dimensional echocardiography before treatment. Results The magnitudes of the falls in systolic, diastolic and mean arterial blood pressure (SBP、DBP、MAP) (all P

Objective To study the relationship of the collection efficiency and physical parameters,such as the height of exhaust hood,baffle,ventilation conditions of these parameters on the effect of control.Methods The computational fluid dynamics software FLUENT was used to form the model,and to maximize production in line with the actual operating conditions for physics experiments,to take air numerical simulation and physical model of re-testing the method of combining.Results Without the lagging conditions,the air flow system should be chosen 1 320 m~3/h,with the lagging conditions,the air flow system should be chosen 1 078 m~3/h.The system in a certain air volume,lower installation height could increase the average wind speed of breathing zone.At a certain suction cover installation height and air flow,the baffle could improve the collection efficiency.Without the baffle,the collection efficiency and control distance(dimensionless)showed a relation of cubic polynomial.Conclusion The physical parameters of suction on the hood may impact the collection efficiency at breathing zone measuring point.

Background Posterior capsular opacification (PCO) following cataract extracapsular extraction is a major cause of the reduction of visual acuity.Topical administration of eye drops is a research hotspot for the prevention of PCO.Objective This study was to evaluate the release of cyclosporine A-loaded chitosan nanoparticles (CyA-CS-NP) by ionic gelation in vitro and its feasibility of modification of the surface of polymethylmethacrylate intraocular lens (PMMA IOL) with CyA-CS-NP.Methods The CS-NP and CyA-CS-NP were prepared by ionic gelation of CS with sodium tripolyphosphate.The characteristics of CS-NP,such as the appearance and mean size,and drug entrapment efficient (EE),loading capacity (LC),and the drug release were studied ; the CyA content on the IOL surface was detected by high performance liquid chromatography (HPLC).The IOL surface modified with CyA-CS-NP was observed by scanning electron microscope and X-ray photoelectron spectroscopy technique (XPS),the changes of elements and chemical bond types between simple plasma processed IOL and CyA-CS-NP modified IOL were analyzed.The transmittance at the wavelength of 360-490 nm and refraction of IOL were detected using back focal length method and spectrophotometer,and the effective resolution of IOL was evaluated according to the instruction of ISO/CD 11979-2.Loops anti fatigue test of IOL referred to the criteria of ISO/CD 11979-3.Results The CS-NP and CyA-CS-NP showed monodisperse,uniform appearance similar to spherical shape with a mean size of (158±18) nm and (219±29) nm,respectively.The CyA-CS-NP had high CyA association efficiency and loading capacity (64.2% and 7.6%).In vitro release study revealed a fast release on the first day followed by a increased drug release during an 11-day following up.The sustained release was approximately 46.6% at day 1 and 77.7% at day 12,respectively.The surface of IOLs with cling film was smooth without CS-NP;while the edge of IOLs appeared a layer of CyA-CS-NP after modification.XPS analysis displayed some elements such as phosphonium,CNH2 and O =CN that appeared on the modified surface,indicating that CyA-CS-NP existed on the surface of IOLs edge.The mean quality of CyA on three IOLs surface after modification was 171.88 μg.The diopter,distinguishing ability and transmittance of modified IOL were (16.64±0.23) D,(90.28 ± 0.25) % and (73.57 ±0.62) %,and those of unmodified IOL were (16.62±0.29) D,(90.28±0.21) %,(73.61±0.60)%,without significant differences between them (t =0.381,0.078,2.291,all at P > 0.05).The antifatigue ability of loops complied with the criteria of ISO/CD 11979-3.Conclusions The optical property and antifatigue ability of loops of the edge-modified IOLs by CyA-CS-NP reach the normal standard and meet the requirement of clinic application.The edge-modified IOLs by CyA-CS-NP can be a delivery system for intraocular drug release.
