Objective To observe the therapeutic effect and effects on nerve conduction velocity of α-lipoic acid combined with monosialoteterahexosyl ganglioside sodium (GM 1) on diabetic peripheral neuropathy (DPN).Methods Ninety-six cases patients with DPN were randomly divided into the observation group (50 cases) and the control group(46 cases).The control group received GM1 40 mg daily though travenous drip,the observation group received α-lipoic acid 600 mg and daily though travenous drip.The course of treatment was 2 weeks in two groups.The effect was observed after 2 weeks,the motor nerve conduction velocity (MNCV) and sensory nerve conduction velocity (SNCV) of median nerve and common peroneal nerve were detected by EMG.Results The total effectiveness of observation group was 94.00％(47/50),higher than that of the control group(71.74％ (33/46),x2=7.0205,P＜ 0.05).After the treatment,MNCV and SNCV of median nerve of observation group and the control group were (47.6813.34)m/s and (43.82±3.10)m/s,(40.23±2.76)m/s,(37.31 ±2.79)m/s,and M NCV and SNCV of common peroneal nerve of observation group and the control group were(42.86±3.16)m/s and (39.47±2.17)m/s,(35.67±2.61) m/s and (32.16±2.50) m/s,all improved compared to before treatment(observation grou:t =7.876,8.428,6.923,7.234;control grou:t =3.572,3.483,3.413,4.182;P＜0.05),and the magnitude of improvement of the observation group was more significant,and the difference was significant compared to control group after six months (t =5.133,3.827,4.634,4.545;P＜0.05).Conclusion α-lipoic acid combined with GM1 in the treatment of DPN can significantly improve the clinical symptoms of patients and improve nerve conduction velocity,is better than the single use of gangliosides,it is worthy of clinical application.

Objective To evaluate the value of transient elastography (FibroScan,FS)in predicting hepatic fibrosis in patients with HBeAg-negative chronic hepatitis B (CHB).Methods One hundred and four patients with HBeAg-negative CHB,who were diagnosed and treated in Hubei Hospital of Traditional Chinese Medicine from June 2011 to May 2013,were enrolled in this study.All patients underwent FS for liver stiffness measurement before liver biopsy.Statistical analysis was applied to compare liver stiffness (kPa)with fibrosis stage (de-termined by liver biopsy).The receiver operating characteristic (ROC)curve of FS was constructed,and the area under the ROC curve (AUC)was calculated to analyze the accuracy of live stiffness in predicting significant fibrosis and cirrhosis.Comparison between groups was made by Kruskal-Wallis H test,followed by Mann-Whitney U test for multiple comparisons.The correlation between two variables was an-alyzed by Spearman rank and Pearson correlation test.Results Liver stiffness gradually rose as the degree of hepatic fibrosis increased, with significant differences between groups (P<0.01 or P<0.05).Liver stiffness was positively correlated with the stage of hepatic fibrosis (r=0.810,P<0.01).The AUC of liver stiffness for detecting liver cirrhosis was 0.956;the cut-off value for diagnosing liver cirrhosis was 13.1 kPa;the sensitivity was 92.7%,and the specificity was 80%.Conclusion FS is a promising noninvasive method for the assessment of hepatic fibrosis in patients with HBeAg-negative CHB;particularly,it has high accuracy in the diagnosis of liver cirrhosis.FS combined with direct or indirect markers may play an important role in differential diagnosis and efficacy evaluation in patients with hepatic fibrosis.

Objective To investigate the prevalence, clinical characteristics and antibiotic resistance of Haemophilus influenzae (HI) in children with acute respiratory tract infection in Suzhou. Methods Data of sputum culture of 3 167 hospitalized childhood patients with acute respiratory tract infection from January 2006 to December 2007 were collected. The incidence of positive HI and the rate of resistance to different antibiotics were calculated and beta-lactamases of the strains were detected. Results About 4.4% of total 3 167 eases were infected with HI. The infection rate was related with season and sex, more frequent between February and June, more common in boys than girls. Children younger than three years old were likely to be infected by HI, eompared with other age groups. The beta-lactamase positive rate of HI was 31.4%. The resistance rates to ampicillin, SMZ + TMP, chloramphenicol, cefaclor, ceftazidime, tetracycline and ampicillin/sulbactam were 29.6% ～ 31.9%, 66.2% -73.9%, 19.7% ～ 15.9%, 2.8% ～ 14.5%, 2.8% ～0、 28.2% ～ 2.9% and 4.2% ～ 1.4% respectively. Isolates resistance to cefuroxime、 ceftriaxone、 imipenem、azithromycin and ciprofloxacin were not found. Conclusions The infection of HI in children with actue respiratory tract infection is closely related with season and sex in Suzhou. Children younger than three years old are at high risk. The beta-lactamase positive rate of HI was high and increased rapidly. Resistance rate to azithromycin, SMZ + TMP and chloramphenicol was high, some isolates were resistant to the second, third generation of cephalosporin. Monitoring the antibiotic resistance of H! should be emphasized.
