OBJECTIVE:To improve the testing method of the related substances in nifedipine sustained-release tablets (Ⅰ).METHODS:The chromatographic condition was in line with the "State Drug Standard".In computing the contents of foreign substances,the standard of "it is negligible if the peak area of foreign substances was less than 10% of the peak area of Nifedipine in the standard solution" was improved to be "it is negligible if the peak area of foreign substances was less than 2%of the peak area of Nifedipine in the standard solution".RESULTS:The contents of the foreign substances determined in accordance with the "National Drug Standard" weresignificantly different from those determined by the improved method (0.00%,0.08%,0.29%,0.14 % vs.0.10%,0.21%,0.51%,0.27%,respectively).CONCLUSION:The improved method can help improve the standard drug quality in that the contents of the foreign substances can be strictly kept under control.

Objective To investigate the morbidity rate and risk factors of post-stroke depression in middle-aged and elderly per-sons with the stroke .Methods From March 2011 to March 2012 ,68 cases of stroke patients were followed up for 6 months after the first stroke .Hamilton Depression Scale-17 ,Activity of Daily Living Scale ,Eysenck Personality Questionnaire ,Scores of Neuro-logical Deficit and Family APGAR Index were used to investigate the morbidity rate and risk factors of PSD in 6 months after the attack of stroke .Results The morbidity rate of PSD was 36 .76% (25/68) in 6 months after the first stroke .Logistic regression a-nalysis indicated that the morbidity rate of PSD was without a clear relationship with age ,whether or not combined with basic disea-ses ,personality ,daily life ability and neurologic impairment .It was closely related with stroke position ,gender ,economy and family care .Conclusion The morbidity rate of PSD is considerable and the major risk factors of PSD are female ,left brain stroke ,poor e-conomic condition and lack of family care .

Objective To explore the clinical effect of atomoxetine on children with attention deficit hyperactivity disorder(ADHD)comorbid tic disorder.Methods The children who met the criteria of Mental Disorders Diagnostic and Statistical Manual diagnostic criteria for ADHD and tic symptoms were given systematic atomoxetine titration reaching the optimum dose.ADHD and tic symptoms were evaluated with ADHD rating scale-Ⅳ(ADHD-RS-Ⅳ)for parents Yale Global Tic Severity Scale(YGTSS),respectively.Results Twenty children with ADHD comorbid tic disorder [17 male,3 female;age range 7.58-17.0 years,mean age(10.55?2.58)years] completing systemic titration was enrolled in the study,including 10 subjects with ADHD-inattentive type,9 mixed type,and 1 hyperactive/impulsive type.The mean optimal dose was(1.19?0.21)mg/(kg?d).The total score(12.65?9.08)scores,inattention score(7.45?4.75)scores and hyperactivity/impulsivity score(3.0)of ADHD-RS-Ⅳ decreased significantly post-treatment compared with pro-treatment(31.10?8.52,17.60?3.09,and 13.0 scores,respectively,P

OBJECTIVE:To observe the clinical efficacy and safety of saxagliptin combined with metformin in the treatment of type 2 diabetes. METHODS:A total of 95 patients with type 2 diabetes were randomly divided into observation group(47 cases) and control group(48 cases). All of the patients received Metformin hydrochloride sustained-release tablets 0.5 g for continuous 4 weeks,orally,3 times a day;based on the treatment,control group was continuously given Metformin hydrochloride sustained-re-lease tablets 0.5 g for continuous 24 weeks,orally,3 times a day;observation group was given Saxagliptin tablets 5 mg continu-ous 24 weeks based on the treatment of control group,orally,once a day;the treatment course was 28 weeks. The clinic data was observed,including clinical efficacy,FPG,2 h PG,bed time glucose,HbA1c,BMI before and after treatment,incidence of hypoglyce-mia,severe hypoglycemia and adverse reactions. RESULTS:The total effective rate in observation group was higher than control group,the incidence of hypoglycemia in observation group was lower than control group(P<0.05). After treatment,the glucose in-dexes in 2 groups was significantly lower than before,and FPG and HbA1c in observation group were lower than control group(P<0.05). There were no significant differences in the BMI before and after treatment,incidence of severe hypoglycemia and adverse reactions between 2 groups(P>0.05). CONCLUSIONS:Saxagliptin combined with metformin has better efficacy and safety than metformin alone in the treatment of type 2 diabetes,and can significantly reduce the incidence of hypoglycemia.

Currently, multimedia teaching plays a more and more important role in colleges.However, the negative effects of multimedia teaching have gradually revealed because of the neglection of its limitations. In this article, strategies were proposed from three different aspects against disadvantages of multimedia teaching in colleges in order to improve its role more effectively.

SUMMARY A 36-year-old woman had an 8-year history of systemic lupus erythematosus (SLE) and was being treated with 10 mg/d of prednisone.She presented with a 6-month history of intermittent fever and multiple painful multi skin erythematous macules in her button, hips and extremities that had slowly en-larged to 8 cm ×4 cm in diameter.The lesions started as painful erythematous macules, which eventually ulcerated and scared.Laboratory tests showed leukopenia, protenuria, positive anti-double strand DNA and hypocomplementemia.Cultures of the bottom ulcer were E.Coli, fugus and Tuberculous mycobacteria were both negative.Biopsy was performed and revealed necrosis of epidermis, thrombus and cellulose de-generation in epidermis with neutrophils karyorrhexis and vasculitis.Her SLE was active, so she was pre-scribed antibiotics for 2 weeks and prednisone was added to 60 mg/d for a month.However her skin ul-cers did not relieve.When prednisone was added to 120 mg/d with combination therapy of cyclophospha-mide and hydroxychloroquine, her skin ulcer cicatrized gradually.

Objective To investigate the iodine nutritional status in the populations of Guizhou Province after implementation of a new standard of salt iodine and to provide a basis in formulating strategy for control of iodine deficiency disorders.Methods In 2011 and 2014,30 units were sampled in Guizhou Province using the sampling method of Probability Proportional to Size.One primary school was chosen in each unit,by the randomized sampling method,40 or 50 students in each school were sampled for examining their urinary iodine level and for testing their household salt iodine level;12 and 50 children were chosen before and after the adjustment,respectively,for testing their urinary iodine level;near the location of the primary school,1 township was chosen,15-20 pregnant women in each township were sampled to test their urinary iodine level.Results Totally 1215 salt samples were collected before adjustment,the median of salt iodine was 32.2 mg/kg;consumption rate of qualified salt was 96.63％;totally 364 urine samples of 8-10 children were collected,the median of urinary iodine (MUI)of children was 308.9 μg/L;450 urine samples of pregnant women were sampled,and their MUI was 216.5 μg/L,among these,121 below 150 μg/L,the proportion was 26.9％.Totally 1 538 salt samples were collected after the adjustment,the median of salt iodine was 26.6 mg/kg;consumption rate of qualified salt was 96.40％;totally 1538urinary samples of 8-10 children were collected,the MUI of children was 218.3 μg/L;and 601 urinary samples of pregnant women were collected,the MUI was 175.1μg/L,among these,241 below 150 μg/L,the proportion was 40.1％.As can be seen from the results,the percentage of sample below 150 μg/L after the adjustment was increased to 13.2％ compared to that before the adjustment,the difference was statistically significant (x2 =19.89,P ＜0.01).Conclusion After implementation of a new standard of salt iodine in Guizhou Province,the iodine nutrition is suitable in residents,but the iodine nutrition of pregnant women is in a trend of declining,which should be noticed.
