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.

Objective This study aimed to study the effect of intra-brachial nitroglycerin administration via the angiography catheter on radial artery spasm in transradial percutaneous coronary intervention. Methods From patients undergoing transradial percutaneous coronary intervention (TRI) and succeeding in coronary angiography (CAG), 810 patients who needed percutaneous coronary intervention (PCI) (including Percutaneous Transluminal Coronary Angioplasty and/or stent implantation) were erolled, including 413 patients in the study group and 397 patients in the control group. When coronary angiography completed, positioned the angiography catheter over brachial artery and patients in the group received an administration of 400μg nitroglycerin via the angiography catheter. The control group received an administration of 400μg nitroglycerin via the sheath. The incidence of RAS were recored and compared. Resultes Baseline characteristics were similar between two groups. In the study group, the incidence of RAS was signiifcatively lower (18 vs. 33, P=0.021). Conclusions Intra-brachial nitroglycerin administration via the angiography catheter can prevent RAS during the insertion of guiding catheter in TRI.

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 know the performance of CT in Xuzhou, and provide references for the allocation optimization of medical resources in effective using of CT in Xuzhou. Methods All hospitals that have large medical equipment in Xuzhou were investigated and the cost, payment and benefit of 42 CT are analyzed. Results The median of cost is 142.6 yuan per person. The median of payment is 277.0 yuan per person. The median of annual net profit is 652 thousand yuan per CT. Conclusion The payment is higher than the cost of CT in Xuzhou. The ratio of profit is 120.8%, but half of CT can't take back of the investment in regular time.
