Objectives To evaluate the valproate plasma l ev els,the clinical efficacy and adverse effects in patients with epilepsy treated with the conventional preparations and the sustained-release preparations of sodium valproate (VPA-Na?SR).Methods 33 patients received oral conventional formul ation of sodium valproate for over six months and a similar dosage of VPA-Na?SR for 4 weeks.After 12 or 24 hours,the valproate plasma concentr ations of the two formulations were measured respectively before taking drugs in the early mor ning.The valproate plasma concentrations and the clinical efficacy of the VPA-N a?SR were assessed by comparing with that of conventional valproate.The adverse effects were recorded.Results The average valproate plasma trough concentration was s ignificantly higher in patients receiving VPA-Na?SR than that of those receiving conventional valproate.Seizure free in patients was achi eved by 76%(n=25) with VPA-Na?SR and by 45%(n=15) with conventional valproate resp ectively.There was statistical difference between the two formulations.The seizu re frequency was significantly reduced in 5 patients treated with VPA-Na?SR.A dverse ef fects were observed in 2 patients with conventional valproate,5 patients with V PA-Na?SR whose valproate plasma levels were higher than that of conventional p reparations.Adverse effects were related to increased valproate plasm a levels and individual drugtolerance. Conclusions The advantage of VPA-Na?SR is that serum valproa te con centrations may increase smoothly and minimize fluctuation in serum dr ug concentrations during a dosing interval. It is a more effective and more convenient antiepileptic agent.

Objective To learn how well these items of Hubei Province meet the quality standards of allowed imprecision. Methods Collected the indoor quality control data of median concentration levels from the laboratories which participated the project of interlaboratory comparisons of clinical chemistry indoor quality control data in Hubei Province.This paper was to analyze the variation coefficient of indoor quality control for 21 routine clinical chemistry examination items which were K,Na,Cl,TCa,P,GLu,Urea,UA,Cr,TP,Alb,TC,TG,ALT,AST,TBil,ALP,AMS,CK,LDH andγ-GT.The other objec-tive was to learn how well these items of Hubei Province meet the quality standards of allowed imprecision.Then took the 1/3 TEa,1/4 TEa,WS/T-403-2012 and minimum imprecision derived from biological variation as quality specification.And an-alyzed the percentage of laboratories in meeting the quality standards.Results The TG,ALT,CK and TBil in more than 50% of the participated laboratories could meet the quality standards of the 1/3 TEa,1/4 TEa,WS/T-403-2012 and the low-est appropriate imprecision derived from biological variation.The Cl and Cr in more than 50% of laboratories couldn’t meet the all above quality standards.The Na and TCa in all laboratories couldn’t meet the quality standards of best imprecision derived from biological variation.The evaluation criterion for qualified items setted was that the variation coefficient in more than 80% laboratories was less than the quality standard.Thus,the percentage of the items which meet the lowest quality standard of biological variation and the all 21 items was the most (66.7%).While the percentage of the items which met the quality standards of the WS/T403-2012 and the best biological variation was the least (14.3%).Conclusion In short,the values of indoor variation coefficient of the 21 items in laboratories which participated the project of interlaboratory compari-sons of clinical chemistry indoor quality control data generally met the requirements.But some items had a little higher de-gree of dispersion.The laboratories should set the appropriate imprecision levels based on the detection capability and quality standards and improve the quality of examination through continuous efforts.

Objective To study the pathogens and drug resistance profiles of pulmonary infection in patients with AIDS. Methods The pathogens and their drug susceptibility of pulmonary infection diagnosed by fibrobronchescopy-induced brunchoalveolar lavage fluid (BAI.F) culture and/or transbronchial biopsy in 116 AIDS cases were analyzed. Results Monopathogenic infection in lungs were detected in 18 cases(15.5%) and mixed infection in 98 cases ( 84.5%). Of the 116 cases, bacteria were present in 91 patients, fungi in 62, tubercle bacillus in 49, pneumocystis jiroveci in 29, and cytomegalovirus in 11.Ninety-five bacterial strains were isolated from BALF, mainly including Streptococci (34), coagulase negative Staphylococcus (20), Klebsiella pneumoniae (10) and Escherichia (7). The isolated bacteria were resistant to β-lactam, macrolides, quinolones and aminoglycosides, of which were 14 methicillin-resistant Streptococci (MRS) strains and 12 extended spectrum β-lactamases (ESBL) strains. Sixty-eight fungal strains were isolated, including 36 Candida mycodermas, 19 Penicilliums, 6 Aspergilli and 5 Mold fungi;they were sensitive to amphotericin B but resistant to fluconazol (5.6% -50. 0% ) and itraconazole( 10. 5%-60. 0% ). Conclusion Pneumonia in AIDS patients are usually caused by multiple pathogens,predominantly consisting of multiresistant bacteria and fungi. Therefore, antibiotics should be rationally chosen according to drug susceptibility test.
