Objective To compare the efficacy and side effect between Paracetamol and Tramadol Hydrochloride Tablet and Paracetamol and Dihydrocodeine Tartrate Tablet on chronic pain. Methods From October, 2013 to October, 2015, 84 patients with chronic pain were divided into group A (n=42) and group B (n=42), who took two Tramadol tablets or Dihydrocodeine Tartrate tablets, three times a day orally for five days. They were assessed with Numerical Rating Scale (NRS), and the incidence of satisfaction and side effect were in-vestigated. Results The score of NRS decreased in both groups after treatment (t>9.402, P<0.001), and there was no significantly difference between them (t=0.461, P=0.941). No significant difference was observed in incidence of pain relief and satisfaction between two groups (χ2=0.979, P=0.323). The incidence of constipation (χ2=5.864, P=0.006) and abdominal distention (χ2=9.946, P=0.002) were less in group A than in group B, but the incidence of nausea was more (χ2=4.934, P=0.026), while the incidence of dizziness, vomiting and tiredness was no significantly different between two groups (χ2<1.451, P>0.061). Conclusion The analgesic efficacy is similar of both drugs, but different in side effects of gastrointestine.

Objective To investigate the important role of bronchial provocation test with hypertonic saline and induced sputum in the diagnosis and treatment of chronic nonproductive cough by assessing its feasibility and the side effects which may occur during the procedure.Methods The diagnosis procedure was based on the anatomical protocol for diagnosing chronic nonproductive cough,howerer,hypertonic saline bronchial provocation test and induced sputum were conducted for unconfirmed 38 pafients who suffered chronic congh.Results 23(23/38,60.5%)patients with airway hyperresponsiveness,the forced expiratory volume in one second(FEV1)was decreased 27%?5.8)%,Side effects occurred in 3 patients(3/38,7.8%).Appropriate sputum samples were obtained after hypertonic saline challeng,The percentage of eosinophi1 counts in induced sputum was high in 24 patients(24/38,63.2%),including cough variant asthma(CVA)(17/23,73.9%)and eosinophilic bronchitis(EB)(7/38,18.4%).After treatment,the percentage of eosinophi1 counts in induced sputum of patients was significantly reduced in CVA and EB.Conclusion Bronchial provocation test with hypertonic saline and induced sputum were an effective method for diagnosing chronic nonproductive cough and little side effects occurred during the procedure.

Objective: To explore the particularity of high school students’ problem behaviors with three-perspective analysis. Methods: Students,parents and teachers were tested by High School Students’ Problem Behavior Questionnaire based on item analysis of open-ended investigation. Results: ①Concerning the identification of problem behaviors,the behaviors such as taking drugs,committing suicide,and stealing got higher scores by students’ self-rating; the behaviors such as running away from home,stealing,and intimidating got higher scores by parent-rating; and the behaviors such as cheating,learning without motivation or objective,and bad learning habits got higher scores by teacher-rating. ②Students,parents and teachers all agreed on the following high frequency problem behaviors; worrying about scores,rarely doing housework,concentration deficits and bad learning habits. ③The frequencies of problem behaviors reported by students were higher than those by their parents. Conclusion: There are significant differences in the identification of problem behaviors among students,parents and teachers,however,the three parts have similar views on the most common problem behaviors.

Objective: To study the relationship between blood pressure (BP) rhythm and cognitive function in elder hypertension patients. Methods: Our research included in 2 groups: Hypertension group:n=74 patients≥80 years and Control group, n=36 elder subjects without hypertension. 24-hour ambulatory blood pressure monitoring (ABPM) was conducted in both groups. According to nocturnal BP reduction rate, Hypertension group was further divided into 4 subgroups as Dipper type BP subgroup, Non-dipper type BP subgroup, Anti-dipper type BP subgroup and Super-dipper type BP subgroup. Cognition function was evaluated by Mini-menta state examination (MMSE) form, MMSE score was compared among different groups and subgroups. Results: By MMSE score, the abilities of orientation, memory, attention, calculation and recall were different between Hypertension group and Control group,P<0.05. By MMSE score, the abilities of orientation and memory were different between Anti-dipper type BP subgroup and Dipper type BP subgroup,P<0.05; the abilities of orientation, memory, attention, calculation and recall were different between Non-dipper type BP subgroup and Dipper type BP subgroup,P<0.05; the memory was different between Super-dipper type BP subgroup and Dipper type BP subgroup,P<0.05. Conclusion: In elderly hypertension patients, compared to those with normal BP rhythm, the abnormal BP rhythm patients had the higher probability to suffer from cognitive dysfunction which was mainly as decreased abilities of orientation, memory, attention, calculation and recall.
