Objective To investigate the clinical curative effects of duloxetine combined with thioctic acid on diabetic painful peripheral neuropathy. Methods Sixty-two patients with diabetic painful peripheral neuropathy were divided into three groups by random digits table: group A(22 patients, duloxetine combined with thioctic acid group), group B (20 patients,duloxetine group) and group C (20 patients,thioctic acid group). The other treatments were same. All patients were treated for six weeks. The pain remission level and nerve conductive velocity were compared among three groups. Results The pain level in three groups was significantly alleviated after treatment (P ＜ 0.01 ). The general effective rate was 86.4%(19/22),70.0% (14/20) and 50.0% (10/20) in group A,group B and group C,respectively (P ＜ 0.05). Visual analogue scales (VAS) in group A was significantly lower than that in group B and group C from the second week after treatment (P ＜ 0.05 ). Nerve conductive velocity was improved in both group A and group C after treatment (P＜0.01),but there was no significant difference between two groups (P＞0.05). In group B,compared with that before treatment,nerve conductive velocity had no significantly improved after treatment (P＞ 0.05). Conclusion Duloxetine combined with thioctic acid can enhance the clinical curative effects on diabetic painful peripheral neuropathy.

Objective To explore medium-term,long-term efficacy of collagenase injected to target site by CT-guided in treatment for lumbar disc herniation. Methods 50 patients with lumbar disc protrusion were treated with CT-guided percutaneous injection of collagenase accurately reaching prominence(target site). Results All patients were followed up 36 to 60 months. The total effective rate was 82.97% (more than 36 months)and82.23%(more than 60 months). Conclusion Grasping indications well, CT-guided percutaneous injection of collagenase target site in treatment of lumbar disc herniation was accurate, safe, simple, effective, and was the preferred treatment for such patients.

AIM: A new HPLC-MS method was developed to determine finasteride in human plasma. METHODS: Two formulations of finasteride tablets were given to 20 healthy male volunteers according to a randomized 2-way cross-over design. The samples were extracted by ethyl acetate under basic conditions, then were separated by C18 column and determined by mass detector. RESULTS: The calibration curve of finasteride was linear and intra-day and inter-day RSD were less than 10 %. The pharmacokinetics parameters of the two formulations (4.5 ± 0.5) h for t1/2; (3.0 ± 0.7) and (2.8 ± 0.9) h for tmax, respectively. The results indicated that there was no significant difference on cmax, A UC0-24, t1/2 or tmax values between the two formulations. CONCLUTION: The relative bioavailability of tablets I with respect to tablets Ⅱ is (99.3 ± 9.2) % by the A UC0-24 measurement, and bioe quivalence is observed between the two tablets.

Objective To study the pathogenic etiology between nasopharyngeal aspirates (NPA) and bronchoalveolar lavage lfuid (BALF) in children with lower respiratory infection. Methods Multiple pathogen in NPA and BALF from 210 cases with lower respiratory tract infection was detected. Seven common respiratory virus (respiratory syncytial virus, adenovirus, in-lfuenza virus A, inlfuenza virus B, parainlfuenza 1, parainlfuenza 2, parainlfuenza 3) were detected by direct immunolfuorescence assay. MP, CP and HBoV were detected by lfuorescence quantitative PCR.HRV and hMPV were detected by RT-PCR. Aspirates were cultured for bacteria. The results of pathogen detection in secretions of upper and lower respiratory tract were analyzed. Results Total positive detection rate of NPA and BALF in 210 cases was 91.9%(193/210), which is higher than that in NPA 75.2%(158/210) and that in BALF 85.2%(179/210). Bacteria detection rate in NPA was 13.3%(28/210), and 8.6%(18/210) in BALF, without signiifcant difference (P=0.118). Bacteria detection rate in NPA and BALF was of poor consistency (Kappa=0.262). Virus detection rate in NPA was 24.3%, which is higher than that in BALF15.2%. BALF-MP detection rate was 77.6%(163/210), signiifcantly higher than that in NPA 53.3%(112/210). There are 95.5%(107/112) cases with positive results in NPA-MP detec-tioncan also be detected in the BALF-MP. MP copies in BALF were signiifcantly higher than that in NPA (4.28×106 vs. 1.31×105), and its positive rate in NPA was still higher than that in BALF. MP detection rate in NPA in children with clinical course of longer than two weeks was much lower than those with clinical course of two weeks or less. Conclusions The pathogen detection of virus and MP in NPA can be used as a reference for lower respiratory tract infection. The joint detection of NPA and BALF can improve the detection power. The sensitivity of virus detection in NPA is higher than that in BALF. NPA pathogen detection of virus and MP is of great important evidence-based medicine in the diagnosis of lower respiratory infection. MP detection rate and its copies in BALF are signiifcantly higher than that in NPA. BALF detection is the supplement of pathogen diagnosis in severe or refractory lower respiratory infections.

Objective: To research the effect of using the campus running APP for extra-curricular exercises on the physical health of college students and the habits formation of extracurricular exercises, and to provide a reference for improving their physcal health level and cultivating exercising habit. Methods: Through experimental method and questionnaire investigation, 1 327 students enrolled in the year 2016 were selected from Shanghai University of Finance and Economics by using cluster sampling method. Running App was used to track their extracurvicular exercises for 7 weeks, and the results were compared before and affer running. Results: The 56-kilometer extracurricular running had a significant difference in the male 1 000 m running index (P<0.05), and the average time spent decreased by 3.69 s. The female test scores in 50 m, forward bends, standing long jumps and sit-ups increased by 0.12 s, 1.83 cm, 2.12 cm and 2.28 respectively, showing statistical significance compared with before running(P<0.01). There was no statistically significant difference for general assessment of male physical test between after and before running (P>0.05); The average score of general assessment of female physical test was significantly higher than that before running, which is statistically significant (P<0.01). Conclusion Using the campus running APP for extracurricular exercises has a positive effect on cultivating students’ sports habits and enhancing their physical health.
