Objective To discuss the effect of inhaling glucocorticosteroid in preventing asthma after bron-chiolitis. Methods 138 bronchiolitis infants were divided into three groups:the inhaling group A,tbe inhaling group B,the control group C. The inhaling group A and B were treated with glucocorticosteroid inhalation, but the inhaling group A had been inhaled pulmicort for six months,the inhaling group B for three months. All infants enrolled in the study and control group were followed up for average two years to observe the wheezing episodes. Results The fre-quency and persistence of wheezing was signfificanfly lower in interfered infants with glucecorticosteroid inhalation [(2.65±1.12)d,(2.89±1.06)d]than that of control group[ (4.06±1.17)d]in two years(all P<0.05) ,but no obvious difference exists between the inhaling group A and B (q= 1.59, P>0.05). Conclusion Glueocorticesteroid inhalation for three months can prevent recurrent wheezing after acute bronchiolitis.

BACKGROUND: Measuring the slope of proximal tibiofibular joint may elucidate the anatomical structure and type of proximal tibiofibular joint, and evaluate the stability of proximal tibiofibular joint. OBJECTIVE: To investigate the measurement methods and clinical significance of the joint slope by comparing the slope measurement of bilateral proximal tibiofibular joint surface on X-ray and 64-row spiral CT reconstruction.METHODS: One hundred normal adult volunteers, including 50 males and 50 females, aged 18-90 years, were photographed in double knees via internal rotation to 30°, 45° and 60°, respectively and scanned with 64-row spiral CT, tibiofibular bone (including knee joints) was reconstructed. The included angle between proximal tibiofibular articular surface and the longitudinal axis of the fibula shaft, between the proximal tibiofibular articular surface and the horizontal line, were measured using an angle square.RESULTS AND CONCLUSION: There were great variations of the data in the same proximal tibiofibular joint measured by X-ray and spiral CT. X-ray results are affected by the site of photograph position, and the slope of articular surface is estimated, so the 64-row spiral CT is an accurate and convenient method to reconstitute the slope of proximal tibiofibular joints. Spiral CT could be used to distinguish the dislocation and instability of the proximal tibiofibular joint, accordingly reduce the clinical misdiagnosis.

BACKGROUND: Female hypertension has its own epidemicologic character and the chief interventions on it are various.OBJECTIVE: To investigate the risk factors of female hypertension and observe the effects on rehabilitative and preventive intervention in demonstrative community for comprehensive prevention and treatment of cardiac cerebral vascular disease in Guizhou.DESIGN: Group randomization was designed. The samples of certain percentage were randomized according to total population from each village of 13 administrative areas.SETTING: Guizhou Institute of Cardiovascular Disease, Renmin Hospital of Yunyan District in Guiyang, Guizhou Clinical Examination Center.PARTICIPANTS: Since 1996, a series of comprehensive prevention and treatment had been carried in the communities for cardiac cerebral vascular disease in Guizhou, involved 13 administrative areas and 112 villagecitizen groups, in which, 26 604 people were employed, living in the regions between town and country. Social natural condition and life behavior of majority citizen reflected the common state of people in town and country. Totally 3 934 people aged over 15 years were investigated in the communities, and were all in the known of investigation. The samples without complete data were excluded.METHODS: ① Base-line investigation was carried on for the groups over 15 years old according to the requirement for administrative region designed by Institute of Preventive Medicine of China Academy of Sciences from April 1st 2001 to May 15th . ② Health education and health promotion activity were carried on for the included groups. ③ Survey after intervention was given for females according to the survey items designed by Institute of Preventive Medicine of China Academy of Sciences from July 2002to June 2003. ④ Normal body-mass index (BMI) was 18.5-23.9 kg/m2,overweight was indicated if BMI was 24-27.9 kg/m2 and obesity was diagnosed if BMI ≥28 kg/m2. ⑤ Analysis was applied on comparison of BMI,waist to hip ratio (WHR), average blood pressure, the rates of incidence,awareness and treatment of hypertension and rate of high-salty and lipid diet. ⑥ t test was adopted for comparison of means between two samples and x2 test was used for rate comparison.MAIN OUTCOME MEASURES: ① Comparison of the rates of incidence, awareness, treatment and control of hypertension for females of different ages in community base-line investigation in Guizhou. ② Comparison of BMI, WHR and BP of females of various ages in baseline investigation.③ Comparison of incident rate of hypertension for females with various BMI in baseline investigation. ④ Comparison of BMI, WHR, BP, smoke, alcohol, rate of high-salty and lipid diet, the rates of incidence, awareness,treatment and control of hypertension for females between baseline investigation and post-intervention survey.RESULTS: In baseline investigation, 6 361 correct and complete forms were collected, with 99.84% qualified rate, of which, there were 3 934females. 1 141 data were qualified after intervention. It was indicated in community baseline investigation: ① Rates of incidence, awareness and treatment of hypertension for females were improved with increased age (P ＜ 0.05), and the control rate was decreased with increased age (P ＜ 0.05). ② BMI, WHR, SBP (systolic blood pressure) and DBP (diastolic blood pressure) and PP (pulse pressure) were improved significantly with in creased age (P ＜ 0.01). BMI for females was increased with ages, but was declined with age ≥60 years. ③ The incident rates of hypertension for groups of normal body mass, overweight and obesity were 15.05%, 23.87% and 39.37% successively, indicating that the hypertension inci dent rate was increased significantly with improved BMI (paired compari son, P ＜ 0.05). Comparison between post-intervention survey and base-line investigation: ① In the comparison, the results of BMI, WHR and BP means were reduced for most cases at same age and significant difference was displayed in majority (P ＜ 0.05). ② After intervention, smoke rate of females was increased significantly and rate of high-salty and lipid diet was decreased (P ＜ 0.05). ③ Incident rate after health intervention was decreased significantly compared with that before intervention (P ＜ 0.05),and the rates of awareness, treatment and control of hypertension were enhanced significantly (P ＜ 0.05).CONCLUSION: ① The rates of incidence, awareness, treatment and control of female hypertension are different in ages in community of Guizhou. ② The severity of risk factor of female hypertension is enhanced with increased age in community of Guizhou. ③ The increased body mass is the important factor of incident rate of hypertension. ④ Health education probably decreases the severity of risk factor of hypertension and increases the rates of awareness, treatment and control.

Objective To observe the effect of acute normovolemic hemodilution(ANH)combined with enhanced recovery after surgery(ERAS)on immune function in patients undergoing hepatic lobectomy. Methods 80 patients were divided into two groups:ERAS group(group E),ANH combined with ERAS group(group AE). bleeding volume,blood transfusion,infused fluid volume,urine output during operation and clinical index after surgery were recorded. Exhaust and defecation time ,fluid intake time and hospitalization duration were also record-ed. Blood samples were obtained from the patients at 30 min before anesthesia induction(T1),immediately(T2), 24 h(T3),3 d(T4)and 7 d(T5)after the end of operation for determination of the expression of CD3+,CD4+, CD8+ on T cells and natural killer cell. Results In group E ,CD3+,CD4+ T-lymphocytes and NK cells at T2-3 decreased as compared with T0. Compared with group E ,no allogeneic blood transfusion cases were found and clinical index duration was shorter in group AE. CD3+,CD4+T-lymphocytes and NK cells at T2-3 increased in group AE as compared with those in Group E. The difference is significant (P < 0.05). Conclusion ANH combined with ERAS can decrease allogenic blood transfusion and increase post-operation immunologic function ,shorten the postoperative hospitalization time.
