Objective To know of the concerning conditions of health information ,the ways to get health information ,and its influence factors among young people .Methods The health information seeking behaviors of people aged from 18 to 44 were inves-tigated by online electronic questionnaire and paper questionnaire from March to April in 2014 .Results 502 valid questionnaires were collected ,including 46 .81% men and 53 .19% women ,mean age was (29 .77 ± 6 .27)years old .40 .96% people were often concerned about the health information ,and 82 .39% people got health information through two or more ways ,the select frequency of the various ways were as follows :computer (77 .20% ) ,television (60 .3% ) ,relatives and friends (58 .70% ) ,mobile phones (54 .87% ) ,newspapers ,magazines ,books (53 .20% ) ,radio (9 .26% )and others 4 .80 % .Gender ,education ,occupation ,medical ed-ucation background ,all of them have effect on the ways of obtained health information ,and the effect of knowledge on the selection of internet pathways was greatest .Conclusion The internet has become the most major ways for people to obtain health informa-tion .The ways to obtain health information are affected by multiple factors ,so relative department should provide some convenient channels according to the characters of each group to get health information .

Objective To analysis residents'death causes in the Three Gorges Reservoir Area,and analysis the distribution of causes of death and age,gender characteristics,therefore provide basis for governments at all levels to develop disease prevention. Methods Data for classification of death cause was analyzed by Excel 2003,according to the ICD-10 classification,the years of po-tential life lost(YPLL)was calculated by SPSS1 7.0.Results Totally 62 702 death date of resident population in Three Gorges Reservoir Area from July,2003 to December,2013 were collected.The crude death rate for males and standardized mortality rate was significantly higher than that in female;Cause of death of the top five were:circulatory system disease,respiratory system dis-ease,malignant tumor,injury and poisoning and digestive system diseases;Chronic disease was the main cause of death which ac-counting for 87.76%;years of potential life lost rate of top five were:injury and poisoning,tumor,circulatory system disease,respir-atory system diseases and perinatal diseases.Conclusion The main cause of death in Three Gorges Reservoir area is a county in the circulatory system diseases,malignant tumor,respiratory system disease,and show a younger trend.Therefore,prevent premature death has become one of the focal points of disease prevention and control.

Objective To observe the analgesia effect of oxycodone hydrochloride injection successive subtraction method background infusion on postoperative analgesia in patients of lobectomy under thoracoscope.Methods Ninety lobectomy under thoracoscope patients, using the random number table method patients were randomly divided into three groups:sufentanil group (group S), the constant speed oxycodone infusion group (Q1) and the decreasing background infusion oxycodone group (Q2), 30 cases in each group. On the time of 10 minutes before the end of surgery, S group was given sufentanil 0.10 μg/kg, Q1 and Q2 group was given oxycodone 0.10 mg/kg, each patient was given intravenous patient-controlled analgesia (PCIA), the group of S set electronic pump sufentanil 2.00 μg/kg (100 ml), background infusion was 0.03 μg/(kg·h), PCA dose was 0.015 μg/kg; The group of Q1 was oxycodone 1.00 mg/kg (100 ml), background dose of 15.00 μg/(kg·h), PCA dose of 15.0 μg/kg; The group of Q2 also was oxycodone 1.00 mg/kg (100 ml), on the first 12 h after operation, the background infusion was 15.00 μg/(kg·h), every 12 h later, the background infusion decreased by 20%, PCA dose was 15.00 μg/kg, all of the pump locking time was 10 minutes, lock 4 times per hour. Recorded the number of hemodynamic on the end of operation, immediate extubation and extubation after 5 minutes. On the time of postoperative 2 h, 8 h, 12 h, 24 h, 48 h, recorded the scores of NRS?, NRS (M), Ramsay. Recorded the times of PCA compression,times of medicaments remedies,the amount of drug use, adverse reactions such as respiratory depression, nausea, vomiting, itching and satisfaction of patients to postoperative analgesia.Results The MAP and HR of three groups of patients were increased in the time of tube drawing (P < 0.05), there was no significantly difference in MAP and HR among the three groups at the end of operation, immediate extubation and after 5 minutes of extubation (P > 0.05). The score of NRS ? in the groups of Q1 and Q2 was lower than group S at the time of (T3~5) (P < 0.05), the score of NRS (M) in the groups of Q1 and Q2 was lower than group S at the time of (T3~6) also. The Ramsay score of Q1 and Q2 group was higher than the group S in the point (T3~7). Which the times of PCA and remedial drug use, sleep disturbed times in the first day and second day of group Q1 and Q2 was lower than the group S (P < 0.05). The volume of drug use at 48 h in the group of Q2 was lower than the group Q1 and S (P < 0.05). Postoperative nausea and vomiting of group Q2 was lowered than group S (P < 0.05). The satisfaction of Patients to postoperative analgesia in the group Q2 and Q1 was higher than group S (P < 0.05).Conclusion Lobectomy under thoracoscope patients with postoperative application of successive subtraction method background infusion oxycodone can obtain satisfactory analgesia effect with a smooth anesthesia recovery period, satisfied analgesic effect, reduce the dosage of drugs and reduce the adverse reaction.
