Objective: To establish a GC method for the determination of content and content uniformity of memantine hydrochloride dispersible tablets.Methods: The sample was dissolved in water, alkalified by sodium hydroxide solution and extracted by methylene chloride.An HP-5 gas chromatography column (50 m×0.32 mm, 1.05 μm) was used.The column temperature was programming increased, and the initial temperature maintained at 120 ℃ for 3 min, and then raised to 220 ℃ at a rate of 10℃·min-1 and maintained for 7 min.A hydrogen flame ionization detector (FID) was used and the split ratio was 1∶1.The inlet temperature was 230 ℃ and the detector temperature was 260 ℃.The injection volume was 1 μl and the carrier gas was nitrogen with high purity at a flow rate of 3.0 ml·min-1.Adamantane was used as the internal standard, and the internal standard method was used for the calculation.Results: The calibration curve was linear over the range of 0.05-1.0 mg·ml -1 (r=0.999 7).The detection limit and the limit of quantification was 1.1 ng and 3.3 ng, respectively.The average recovery was 100.2% (RSD =0.73%, n=9).Conclusion: The method has the advantages of simple operation, small extraction process toxicity, little environmental pollution, high accuracy and high specificity, and can be used for the determination of content and content uniformity of memantine hydrochloride dispersible tablets.

Objective To determine the diagnostic value of ractional exhaled nitric oxide (FeNO) in eosinophils (EOS) bronchial asthma and its significance in appraising of therapeutic reaction of inhaled corticosteroids (ICS) for EOS bronchial asthma.Methods A total of sixty-two patients with bronchial asthma in the First Mfiliated Hospital of Xinxiang Medical University from April 2015 to February 2016 were selected as asthma group;at the same time,sixty-two healthy people were recruited as control group.The patients in asthma group were divided into EOS asthma group(n =31) and non EOS asthma group (n =31) according to the induced sputum cell count;the patients in EOS asthma group were divided into mild (n =7),moderate (n =13) and sever asthma group (n =1 1) according to the severity of the disease.The patients in asthma group were given conventional therapy(doxofylline 0.2 g intravenous infusion,two times per day;oral cetirizine 10 mg,one time per night;oral montelukast 10 mg,one time per night;budesonide 2 mg and compound ipratropium bromide solution 2.5 mL by aerosol rebreathing method,two times per day) for seven days.The pulmonary function,asthma control test(ACT) score,FeNO level and the ratio of EOS of patients were detected before and after treatment;the FeNO levels of person in the control group were tested.The FeNO levels of subjects were compared in each group;the correlation between FeNO level and EOS ratio was analysed in asthmatic group;the controlling rates of patients in asthmatic group were compared.Results Before treatment,the FeNO level in control group and asthma group was (9.57 ± 6.61),(30.23 ± 8.9 1) ppb respectively;the FeNO level in control group was significantly lower than that in asthma group (t =7.414,P ＜ 0.05).Before treatment,the FeNO level of patients in EOS asthma group and non EOS asthma group was (59.62 ± 29.04),(18.20 ± 11.33) ppb respectively;the FeNO level in non EOS asthma group was lower than that in EOS asthma group (t =6.568,P ＜ 0.05).In asthma group,the level of FeNO was positively correlated with EOS ratio(r =0.823,P ＜ 0.05).There was no statistic difference in FeNO level of patients in non EOS asthma group before and after treatment(t =2.013,P ＞ 0.05).The FeNO levels of patients in EOS asthma group after treatment were significantly lower than those before treatment (t =7.740,P ＜ 0.05);the FeNO levels of patients in mild,moderate and sever asthma group after treatment were significantly lower than those before treatment(t =3.535,8.171,7.161;P ＜0.05).The control rate of patients in EOS asthma group(67.7％,21/31) was significantly higher than that in the non EOS asthma group(22.6％,7/31) (x2 =12.765,P ＜0.05).The control rate of patients in mild,moderate and sever asthma group was 28.6％ (2/7),76.9 ％ (10/13) and 81.8 ％ (9/11) respectively;the control rate of patients in mild asthma group was significantly lower than that in moderate and sever asthma group (x2 =6.418,7.103;P ＜ 0.05);there was no statistic difference in control rate of patients between moderate asthma group and sever asthma group(x2 =7.103,P ＞ 0.05).Conclusion FeNO level can reflect the degree of airway inflammation,and can be used for the diagnosis of EOS phenotype asthma,and also has certain clinical value in evaluating the therapeutic reaction of ICS for treatment of EOS asthma.

Objective To develop a Chinese military psychosomatic health scale(CMPHS) and examine its reliability and validity. Methods Based upon the previous researches, the Scale was compiled according to open-ended inventory survey. The data was collected from 1050 subjects chosen by random cluster sampling. 60 of them were tested with the CPSHS at the same time, while 61 of them were retested with the CMPHS after two weeks. The reliability and validity were examined by exploratory factor analysis ( EFA) and correlation analysis. Results According to the factor analysis results, 11 factors were extracted, namely espiratory apparatus, alimentary system,skeletal and musculature,integument,regeneration and endocrine,nervous system, anxiety, depression, psy-choticism and family history. There were 91 items in the formal scale when one lie subscale was added. The correlation between subscales were 0. 103 ～ 0. 778 (P < 0. 01) , the correlation between subscales and total scale were 0.600 ～0.859(P<0.01). The test-retest correlation coefficients of total scale and subscales were 0.427 ～0.901 (P < 0.01); the Cronbach (α) coefficients were 0. 643 ～ 0. 935 (P < 0. 01) ; and the split-half correlation coefficients were 0. 349 ～ 0. 855 (P < 0. 01 ). The correlation coefficients were 0. 425 ～ 0. 979 (P < 0. 05 or 0. 01 ). Conclusion The Chinese military psychosomatic health scale has acceptable psychometrics properties on reliability and validity.

Objective To evaluate the test-retest and inter-rater reliability of the hand-held pressure algometer as a measuring instrument of pressure pain threshold(PPT).Method A total of 37 healthy subjects were recruited for reliability test.Three raters measured the PPT at 12 body sites of the subjects.Each rater conducted three trials on each site.In the validity test,10 patients with active trigger points in the upper trapezius were recruited and measured by one rater using the pressure algometer for PPT,the visual analogue scale(VAS)was also used to evaluate the pain intensity induced by the trigger point.The intraclass correlation coefficient and Spearman correlation coefficient were calculated to reflect the reliability and validity.Results The test-retest and inter-rater reliabilities were both high(ICC＞0.95),with the measurements by one rater were more reliable than measurements by multiple raters.The inter-rater reliability of PPT measurement obtained by using the mean value of 3 trials was higher than any of the 3 trials alone.The PPT values of the trigger points were higher than those of the normal points,and there was a significantly negative correlation between the PPT values of the trigger points and the VAS scores.Conclusion The intra-and inter-rater PPT measurements in healthy subjects obtained with the hand-held pressure algometer were highly reliable.The algometer was valid for quantifying myofascial trigger point sensitivity.
