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.

Purpose To evaluate the value of acoustic radiation force impulse (ARFI) imaging in the diagnosis of SjOgren's syndrome (SS).Materials and Methods Sixty-four cases of outpatients or inpatients with xerophthalmia or xerostomia in the Department of Rheumatology and Immunology of the First Affiliated Hospital of Nanchang University from September 2015 to April 2016 were collected.According to American-European Consensus Group criteria of 2002,the subjects were divided into SS group (n=38) and nonSS group (n=26).The bilateral parotid gland and submandibular gland were examined by ARFI imaging,and the shear wave velocity (SWV) value was obtained.The differences in SWV values between the left and right sides of the parotid gland or submandi-bular gland and between the SS group and the non-SS group were analyzed.Results ① The SWV values between two sides of parotid glands or submandibular gland in SS group or non-SS group showed no significant differences (P＞0.05).The difference of SWV between the two groups was statistically significant (P＜0.05).② According to the ARFI imaging of parotid gland,the optimal cutoffvalue,sensitivity,specificity,Youden index and ROC area under the curve were 1.99 m/s,86.3％,80.8％,0.671 and 0.879,respectively.③ According to the ARFI imaging of submandibular glands,the optimal cutoff value,sensitivity,specificity,Youden index and ROC area under the curve were 2.13 m/s,79.5％,80.8％,0.603 and 0.878,respectively.Conclusion The ARFI imaging can provide the SWV value of salivary glands to quantify the elasticity of salivary glands in SS,which has great value in the diagnosis of SS.

Objective To analyze the risk factors of pulmonary embolism in patients with negative Ddimer in serum in order to determine the need of pulmonary computed tomography angiograph (CTA) to confirm the final diagnosis in those patients for avoidance of misdiagnosis.Methods A retrospective analysis of 106 patients suspected to suffer from pulmonary embolism (PE) with serum negative D-dimer checked with pulmonary CTA was carried out.According to the results of CTA, the patients were divided into two groups, namely PE group (n =41) and non-PE group (n =65).The difference in clinic presentation, the time elapsed from onset to visit, N-terminal pro-brain natriuretic peptide (NT-proBNP), high risk factors (such as immobilization for 3 weeks, leg swelling and pain to palpation, history of deep vein thrombosis, malignancy) and Wells score (≥ 4 points indicates probability of PE).And logistic regression analysis was made to investigate the risk factors in PE with negative D-dimer.Results The analysis study showed that 38.6％ of total patients suspected to suffer from PE with serum negative D-dimer were checked by CTA to confirm the presence of PE.One important characteristics of the D-dimer negative PE patients was the longer time consumed from onset to visit [(9.51 ±2.01) d vs.(4.01 ±1.92) d, P＜ 0.05], and majority of the CTA positive patients suspected to suffer from PE with negative D-dimer had high risks of PE (P ＜0.01).Compared with the non-PE group, the Wells score ≥4 points and the level of serum NT-proBNP significantly increased in the PE group (P ＜ 0.01).Logistic regression analysis revealed that dyspnea, high NT-proBNP level and Wells sore ≥ 4 points were risk factors for D-dimer negative PE.Conclusion Delayed treatment was the main cause of misdiagnosis of D-dimer negative PE.Dyspnea, high NT-proBNP level and Wells sore ≥4 points were risk factors for suspected PE patients with negative D-dimer, and these patients should be confirmed by pulmonary CTA.On the contrary, PE could be excluded if patients with D-dimer negative had no these risk factors.

Objective To explore the inheritance characteristics of SCN1A gene in familial severe myoclome epilepsy in infancy.Methods The clinical information and blood of the patients and their relatives who had febrile seizure(FS)or epilepsy history were collected.Blood genome DNA were extracted.All exons of SeN1A gene were PCR amplified and screened with denaturing high Performance liquid chromatography(DHPLC)technology,and sequence analysis was performed.Results Fourteen SME patients had FS or epilepsy family history.Five were found positive history in first class relatives and 2 of them had inherited mutations of SCN1A(C.4284+2T>C and e.1216G>T):Other9 were found positive history in second class relatives and 2 of them had de novo mutations of SCN1A.Condusions SCN1A is the pathogenic gene for SME.The same muatation of SCN1A gene can be related to different clinical phenotypes.SME patients whose first class relatives with FS or epilepsy history should be taken as the focus of SCN1A inherited mutation screening.

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.

Objective To assess the clinical application of Cylex ImmuKnow assay in patients with renal dysfunction after liver transplantation for individualized immunosuppressive therapy.Method Twenty adult patients undergoing liver transplant between January 2009 and December 2011 received regular ImmuKnow assay monitoring combined with determination of serum tacrolimus trough concentration to guide immunosuppressive regimens,all of whom showed sustained renal dysfunction 6 months after transplant with normal and stable liver function.Clinical data were collected to observe the changes of renal function in those patients after treatment.Results The recipients were followedup for 15-54 months,received ImmuKnow assay 61 times and the results fluctuated 33-943 μg/L [median 282 μg/L,interquartile range (IQR) 267 μg/L].After ImmuKnow monitoring,serum creatinine level in patients was decreased significantly from median 151.8 μmol/L with IQR 44.9 μmol/L to median 114.9 μmol/L with IQR 35.3 μmol/L (Z =-3.845,P =0.000),and estimated glomerular filtration rate (eGFR) was increased significantly from median 0.746 mL/s with IQR 0.025 mL/s to median 1.005 mL/s with IQR 0.454 mL/s (Z =-3.771,P =0.000).ImmuKnow results showed a linear correlation with the white blood cell count in patients (Spearman correlation coefficient r =0.429,P =0.001),but no linear correlation with the patients' age,primary disease before transplantation,postoperative time,serum tacrolimus trough concentration,lymphocyte count,CD3+ T lymphocyte count,CD4+ T lymphocyte count or CD4+/CD8+ T lymphocyte ratio (P＞ 0.05).Conclusion Cylex IrmmuKnow assay can be applied in patients with renal dysfunction after liver transplantation for individualized immunosuppressive therapy monitoring,which is of certain clinical value.

Objective To establish a molecular inversion probe ( MIP) method for detection of single base drug-resistance mutation in Hepatitis B virus ( HBV) gene.Methods The HBV wild type and YVDD mutant strain were isolated by Daping Hospital of the Third Military Medical University.The MIP was designed and applied to detect the HBV drug-resistance YVDD mutation in one case of wild type and one case of YVDD mutant HBV strain isolated previously.The results of MIP method were compared with that of sequencing to evaluate the detection accuracy.Results Thermal cycling single-base extension and connection reaction performed by Taq DNA Ligase and Ampligase DNA Ligase could ensure the specificity of the detection.The optimum probe concentration of MIP was 1 nmol/L.Through detection of the target gene with different DNA concentrations , the detection sensitivity of MIP was determined as 1 nmol/L.The results of MIP were consistent with that of sequencing method in detection of the clinical samples.Conclusion MIP is successfully used to detect single-base drug-resistance mutation in HBV gene.
