Objective:To understand the difference of prevalence rate and main symptoms of northwest dryness syndrome(NDS) of the long staying and temporary residents at Xinjiang by comparing the cotton workers in Shihezi come from mainland with inhabitant of Xinjiang,under the environment of NDS.Methods:To design questionnaire according to the Chinese medicine theories and modern epidemiology method,and carry out sampling questionnaire in cotton workers of Shihezi,Hetian,Urumqi,Yili and Leshan,then carry out syndrome differentiation with computation and statistical analysis about NDS.Results:The distributing date,syndromic types and main symptoms scores of NDS in the cotton workers in Shihezi and other areas were obtained from 3658 questionnaires.The highest attack rate of NDS on cotton workers was in Hetian.The attack rate in Sichuan was higher than that in Shizihe(P0.05).The higher scores,symptoms of DNS in Shizihe were the main symptoms of dryness syndrome,but the higher scores,symptoms of NDS in Hetian,Yili and Urumqi were the characteristic symptoms.The external-dryness score of cotton workers in Shihezi was obviously higher than that in other areas(P

Objective To investigate early nasogastric nutrition on patients with acute decompensated chronic heart failure,and observe its influence on patient's disease outcome.Methods From January 2012 to December 2013,100 cases with acute decompensated chronic heart failure were used as the research subjects,were randomly divided into experimental and control groups with 50 cases each group.Patients of two groups adopt expansion of blood vessels,strong heart,diuresis,and routine anti-infection treatment;Based on this scheme,experimental group adopt early nasogastric nutrition.The cardiac function index,the change of nutritional status and clinical curative effect and the result of follow-up within 1 year after discharge of two groups were compared.Results Left ventricular end-diastolic dimension (LVEDD) and left ventricular end-systolic dimension (LVESD) in two groups after treatment were decreased,and the descender of experimental group was superior to that of the control group with statistically significant difference (P ＜ 0.05).After treatment,left ventricular ejection fractions (LVEF) of two groups were improved,and the rise of experimental group was superior to that of control group with statistically significant difference (P ＜0.05).In the two groups after treatment,the serum brain natriuretic peptide (BNP) levels were significantly decreased,and the descender of the experimental group was more than that of control group with statistically significant difference (P ＜ 0.05).After treatment,body mass index (BMI),the level of serum prealbumin (PA),transferrin (TRF),and the total number of lymphocytes of two groups were increased significantly (P ＜ 0.05);and BMI,the level of serum PA and TRF,and the total number of lymphocytes of the experimental group were significantly better than those of the control group (P ＜ 0.05).The total effective rate of the experimental group was significantly higher than that of the control group (P ＜ 0.05).The exacerbation rates,readmission and mortality rate of experimental group follow-up within 1 year after discharge were significantly lower than that of the control group (P ＜ 0.05).Conclusions The early nasogastric nutrition on the patients with acute decompensated chronic heart failure was better able to improve patients' nutrition state,more conducive to patients with cardiac function recovery,improve the clinical curative effect,and reduce the exacerbation rates,and readmission and mortality rate.

Objective To investigate the epidemiologic characteristics of injuries of children aged 0 ~14 yrs. Methods Described analysis was used to analyze the epidemiologic characteristics about the age, gender, injury type and cause in children 0~14 years old who visited in emergency department of hospitals form 2006 to 2007. Results During the study period, 16 124 injured children were collected. the rank of injuries type were contused/abrased wound (44.41%), open injury (36.10%), sprain (12.81%), bone fracture (3.25%) and burn/scald injury (1.49%); the cause of injuries were fall down (55.24%), animal injury (21.49%) , blunt injury (8.47%) and traffic injury (6.96%); The common place of injury occurred were at home (53.66%), public and resident place (18.01%), road/street (11.73%) and school (10.70%). The gender ratio was 1.94, the median age was 6 years, the male injury was decrease with the age increase, but so wasn't the female. Conclusion Injury gradually becomes the key health problem and influences the children health. The effective measures should be taken in term of the epidemiology characteristics of the injuries among children at 0-14 to prevent and control injury occurring. The health education of preventing injury occurring and behavior drawback should be conducted as early as possible to raise awareness of injury issues among children in the kindergartens and promote them growing healthily.

In order to study mechanical stress on root from orthodontic tooth movement by sliding mechanics, a 3-dimensional finite element model incorporating all layers of a human mandibular dental arch with orthodontic appliance has been developed to simulate mechanical stress on root from the orthodontic tooth movement. Simulated orthodontic force of 2 N at 0, 30 and 45 degree from the horizontal axis was applied to the crown of the teeth. The finite element analysis showed when orthodontic forces were applied to the tooth, the stress was mainly concentrated at the neck of the tooth decreasing uniformly to the apex and crown. The highest stress on the root was 0.621 N/mm(2) for cervical margin of the canine, and 0.114 N/mm(2) for apical region of the canine. The top of canine crown showed the largest amount of displacement (2.417 microm), while the lowest amount of displacement was located at the apical region of canine (0.043 microm). In conclusion, this model might enable one to simulate orthodontic tooth movements clinically. Sliding force at 2 N is ideal to ensure the bodily orthodontic tooth movement. The highest stress concentration in the roots was always localized at the cervical margin when orthodontic force of 2 N at 0, 30 and 45 degree from the horizontal axis, so there may be the same risk of root resorption when orthodontic force of 2 N at 0, 30 and 45 degree was used in clinic cases.

OBJECTIVE: To explore the application of the Dexmedetomidine utend drug induced sleep endoscopy. METHOD: Forty-four OSAHS patients diagnosed by PSG randomly were divided into group A (Dexmedetomidine group) and group B (Propofol group), each group of 22 cases. Group A: pump the Dexmedetomidine (1 microg/kg) over 15 minutes. Once the patient reached a satisfactory level of sedation, the electronic nasopharyngoscope was introduced into the nasal cavity group B: the propofol (2 mg/kg) was intravenous injected, use the same exmination after the object patients falling asleep. If not, double the injection dose of the two group. Observe and record the patient vital signs, EEG and sleep time, and handle the complications. RESULT: The study was successfully completed both in group A and B. Mean arterial pressure (MAP) in group B was lower than group A during the examination significantly (P < 0.05). The time falling to sleep in two groups were (13.4 +/- 2.5) min and (6.6 +/- 1.2) min, and the time in group A was much longer than that in group B. The lowest oxygen saturation during the examination in two groups were 0.835 +/- 0.096 and 0.691 +/- 0.095, and the difference was statistically significant. There was no incidence of adverse reactions in two groups. CONCLUSION Compared with propofol, Dexmedetomidine is a safer sleep-inducing drug, and it can be used for clinical sleep endoscopy.

Objective:To investigate the clinical value of serological test indicators in the identification of primary and metastatic liver cancers. Methods:We detected the serum levels of ALT, AST, ALP, TBIL, DBIL, GGT, CHE, 5'-NT, CA199, CEA, and AFP in primary hepatic carcinoma (PHC;120 cases), metastatic hepatic carcinoma (MHC;135 cases), and no liver metastatic control (135 cas-es) groups. The methods used were variance analysis and Scheffe test. ROC curve analysis was used to determine the diagnostic value of CA199 , CEA, and AFP in PHC and MHC. Results:The difference between the serum levels of AST, ALP, GGT, 5'-NT, AFP, and CEA of the PHC and MHC groups was statistically significant (P<0.05). The AFP, CEA, and CA199 areas under the ROC curve of the PHC and MHC groups revealed that AFP diagnosis of primary liver cancer had certain accuracy, whereas CEA and CA199 have some diagnostic value in differentiating primary and metastatic liver cancers. Conclusion: The detection of serum levels of AST, GGT, 5'-NT, AFP, CA199, and CEA in malignant tumor was a preliminary diagnosis of liver metastasis and can provide evidence for the dif-ferential diagnosis of PHC and MHC.
