Objective:Three-dimensional (3D) ultrasound (US) is increasingly being introduced in the clinic,both for diagnostics and image guidance.Although dedicated 3D US probes exist,because of its expensive cost,3D US can also be acquired with the still frequently used two-dimensional (2D) US probes.Methods:Obtaining 3D volumes with 2D US probes is a two-step process.First,a positioning sensor must be attached to the probe for 2D image matching;second,a reconstruction of a 3D volume can be performed into a regular voxel grid.Results:This paper presents a way to realize the 3D US in irled-based Image Guided Radiotherapy using a homemade 2D US.Conclusions:The experiments demonstrate a method of saving costs and having advantages in clinic application.

The fermentation conditions of alkaline lipase producing by Pseudomonas cepacia PCL-3 were optimized.Based on the analysis of single factorial experiments,dextrin was the most suitable carbon source,peptone and urea were the suitable compound nitrogen sources among the examined materials.Three significant factors(urea,inoculum and initial pH) were selected from the eight factors related to lipase production by Plaekett-Burman method,and were further optimized with response surface analysis.And then,steepest ascent procedures were applied to define the optimal response region of the three factors.The obtained optimal conditions were urea 0.15%,inoculum 3.05% and initial pH 8.38,under which conditions,the enzyme activity was improved from 25.37 U/ml to 48.88 U/ml,enhanced 1.93 folds.Starting from the flask conditions,the highest lipase activity of 47.69U/ml was achieved by batch fermentation in a 10 L fermentor after 52 h of the cultivation.

Objective To optimize the extraction process f or polysaccharide in the residue of Fructus Jujubae(FJ ).Methods The conditions of extraction process for polysaccharide of FJ was screen ed with the yield and content of polysaccharides as markers by orthogonal experimental design.Results The optimum extraction process was:soaking the residue of FJ with water at 90℃for3times(5hours each time )and precipitated with 80%ethanol.T he yield and content of polysaccharides were 20%and 43.54%respectively.Conclusion This procedure is reliable and polysac-charides can be extracted completely by this procedure.It can bring a hig h economy benefit.

Objective:To observe the expression of Th1 versus Th2 type cytokines in primary hepatic cancer(PHC)and its adjacent liver tissues.Methods:The gene expression of Th1/Th2 cytokines was detected by RT-PCR using IFN-?and IL-2 as Th1 type cytokine genes,IL-4 and IL-10 as Th2 type cytokine genes.Results:Thl type cytokines were expressed in 7 and 9 cases,while Th0 type cytokines in 4 and 2 among 11 PHC and their adjacent liver tissues,respectively.Conclusion:Th1 type cytokines are expressed predominantly in primary hepatic cancer and its adjacent liver tissue.

Objective To evaluate the efficacy of radiosynovectomy with 32P colloid in haemophilic synovitis of adolescents. MethodsRadiosynovectomy with 32P colloid was primary performed on 26 male haemophilic patients(26 joints),whose average age was 16 years(11 to 21 years).The average dose of 32P colloid was 2.1 mCi(1.0 to 3.0 mCi). Results After 6-month interval,haemarthrosis was reduced by no less than 30% in 23 patients,with a total efficacy of 88.5%.The mean frequency of haemarthrosis was reduced from 1.9 per month of presynovectomy to 0.3 per month of postsynovectomy(P

Objective To explore the effects of lifestyle intervention on index of early artery diseases in nondiabetic patients with metabolic syndrome (MS). Methods Eighty-seven nondiabetic patients with MS were randomly assigned to the intervention group ( n =47) and the control group ( n =40).The patients in the intervention group received health education,diet control,regular physical exercises,and unhealthy habit correction; however,the control group did not receive any intervention.All the patients were followed up for 9 months.Body mass index (BMI),waist circumference (WC),systolic blood pressure (SBP),diastolic blood pressure (DBP),triglyceride (TG),total cholesterol (TC),high-density lipoprotein cholesterol ( HDL-C ),low-density lipoprotein cholesterol ( LDL-C ),fasting blood glucose (FBG),HbAlc,fasting insulin (FINS),HOMA-IR,high sensitivity C-reactive protein (hs-CRP),carotid intima-media thickness (IMT),brachial-ankle pulse wave velocity (baPWV) and ankle-brachial index(ABI) were measured at baseline and at 9 months.ResultsAfter 6 or 9 months' intervention,BMI,WC,SBP,TG,HDL-C,FPG,HbAlc,FINS,HOMA-IR and hs-CRP of the intervention group were improved (all P ＜ 0.05). HDL-C,FPG,HbAlc,FINS,HOMA-IR and hs-CRP of the intervention group were further improved at 9 months when compared to 6 months ( all P ＜ 0.05 ). In comparison with the control group,BMI,WC,HDL-C,FPG,HbA1 c,FINS,HOMA-IR and hs-CRP were significantly improved in the intervention group at 9 months ( all P ＜ 0.05 ).After 6 or 9 months' intervention,baPWV and ABI were significantly changed ( both P ＜ 0.05 ) in the intervention group although IMT of the carotid did not changed (P ＞0.05). BaPWV and ABI were significantly changed in the intervention group when compared with those in the control group at 9 months ( both P ＜ 0.05).The abnormal rate of baPWV in the intervention group at 9 months was 44.68％. BaPWV and ABI were associated with hs-CRP and HOMA-IR.ConclusionsIn nondiabetic MS patients, health management could significantly improve insulin resistance,modify metabolic disorders,and prevent the development of atherosclerosis.

This paper reviewed the reports, published in recent years in China, concerning the mechanisms of Chinese herbal medicines in treating chronic obstructive pulmonary disease (COPD), trying to find out its preponderant targets and links, for elevating the level of TCM for prevention and treatment of COPD.

OBJECTIVETo study the influence of 14- day simulated weightlessness on emotional behaviour in rats.

METHODSSixteen from twenty male SD rats were selected and assigned to a 2-group design: the control group and the tail suspension (TS) group (n = 8). The essay deployed typical methods for assessing emotional activity in the current, including food-intake and body weight variation, open field testing, sucrose preference testing and the evaluation of emotional arousal level to test emotional behavior.

RESULTS1. After 14- day simulated weightlessness for rats, their food-intake and body weight increase were less than those in the control group. 2. The ability of movement reduced in rats, the number of locomotion was significantly lower than that in the control group (P < 0.05) and the frequency of self-grooming was significantly higher than that in the control group(P <0.01. 3. A higher level of emotionality in TS group was recorded. 4. Sucrose preference was not observed in TS group.

CONCLUSIONIt demonstrated depression, anxiety and nervous symptom occurred in the TS rats with a certain degree of nervous reaction but no anhedonia.
