Objectives: Observe the effects of acupuncture on obese SD rats fed by self-prescribed high calorie diet. 　Methods: The model group were male SD rats fed by self-prescribed high calorie diet, while the control group were male SD rats fed by common roughage. After acupuncture, the changes of some indexes were observed such as eating and drinking amount,body weight,length, Lee index,fattiness in groin and circumrenal areas, TG,TC,BG levels in blood etc.　 Results: The obesity was defined as the average body weight of the model group was 20% heavier than the average body weight in the control group. And the obesity ratio was 56%. The indexes were changed in different degrees with statistic significance after one period of treatment.　 Conclusions: Over-nutrition is one of the causes of obesity. Our high calorie feed for obese rat is reasonable. Acupuncture has obvious therapeutic effects for simple obesity.

Objective To study the influence of continuous blood purification(CBP)on the intra-abdomi-nal pressure (IAP ) and the gastrointestinal dysfunction of intra -abdominal hypertension (IAH ).Methods 80 patients with IAH were selected and divided into observation group and control group(n=40)according to random number table method.The observation group was given 3d CBP therapy.The control group was given conventional treatment.The mean arterial pressure (MAP ),IAP and abdominal perfusion pressure (APP ) were detected.The number of gastrointestinal symptoms was observed,sequential organ failure score(SOFA score)was used to assess the organ function of the two groups before and after treatment.Results The MAP,IAP,APP,SOFA score of the two groups before treatment had no statistically significant differences(P>0.05).The MAP of the two groups after treat-ment[(88.46 ±8.93)mmHg vs.(87.76 ±8.04)mmHg]had no statistically significant difference(P>0.05).The IAP[(9.02 ±1.06)mmHg]and SOFA score[(1.32 ±0.45)]of the observation group after treatment were signifi-cantly lower,the APP [(85.34 ±7.59)mmHg]was obviously higher than before treatment and the control group [(19.54 ±4.23)mmHg,(5.24 ±2.05)points,(70.76 ±6.43)mmHg],the differences were statistically significant (t=3.575,2.855,3.274,3.563,3.114,3.782,all P<0.05).Before treatment,the number of the gastrointestinal symptoms of the two groups[(44.56 ±8.53)times vs.(45.32 ±8.21)times]had no statistically significant difference (P>0.05).The number of gastrointestinal symptoms of the observation group after treatment [(6.54 ±2.24)times] was obviously lower than before treatment and the control group [(15.45 ±4.43)times],the difference was statisti-cally significant(t =3.022,P<0.05 ).The 30 d and 60 d survival rates of the observation group were 87.5%(35/40)and 65%(26/40),which of the control group were 80.0%(32/40)and 55%(22/40),although which of the observation group were higher than the control group,but there were no statistically significant differences(P>0.05 ).Conclusion CBP could significantly reduce the IPA of the patients with IAH,raise the APP,improve gastro-intestinal perfusion,reduce gastrointestinal symptoms,has positive significance to improve the gastrointestinal dysfunction.

To investigate the change in renal CD11a and myeloperoxidase (MPO) contents and renal function during ischemia-reperfusion injury (IRI) of rat kidney, as well as the role of lymphocyte function associated antigen-1 (LFA-1) played in renal IRI, we utilized a rat model of renal IRI to detect the renal tissue contents of CDlla and MPO and renal functioa The results showed that the levels of CD11a and MPO were very low in normal renal tissue, but increased significantly in ischemia reperfusion. Renal failure was presented in rats with IRI. The levels in the ischemia-60min-reperfusion group were higher than those in the ischemia-30min-reperfusion group in the same time points. Our conclusion is the levels of CD11a and MPO in rat renal tissue increase significantly during renal IRI. LFA-1-mediated leukocyte adherence plays an important role in renal IRI. Up-regulation of CDlla further elucidates the mechanism of relation between IRI and acute rejection: more heavier IRI is, more possible acute rejection would be.

Objective To evaluate sound velocity tissue quantification ( SVQ ) for the quantitative assessment of liver fibrosis stage in chronic hepatitis B ,and to evaluate the correlation between diagnostic performance of sound velocity tissue quantification and blood parameters . Methods From the May of 2013 to May of 2014 ,collect ninety‐nine patients with chronic hepatitis B who was diagnosed by clinic and / or liver biopsy as experiment group ,and thirty healthy volunteers as control group at the same time . The experiment group and control group were evaluated with to measurement the zone speed index ( ZSI) ,and blood cell count . The AST/PLT ratio index ( APRI) was calculated according the following formula , APRI=AST(ULN)/PLT(109/L) . The liver biopsy was performed in the same day with SVQ and all blood parameters .ZSI and APRI were compared by correlation with liver fibrosis stage in chronic hepatitis B . Referring to the histologic fibrosis stage on liver biopsy ,all the ZSI and the APRI value were assessed by using ROC curve analysis . The corresponding cut‐off value ,sensitivity and specificity were also calculated andcompared.Results 1)ThemeanvaluesofAPRIwere(15.9±5.7)m/sforpatientswithS0,(28.1± 2 .8)m/s for patients with S1 ,(35 .8 ± 1 .2)m/s for patients with S2 ,(42 .6 ± 0 .8)m/s for patients with S3 , and (46 .3 ± 1 .3)m/s for patients with S4 .2)Accordingly ,the areas under the ROC curve for ZSI and APRI were 0 .875 and 0 .762 for S≥S1 ,0 .832 and 0 .597 for S≥S2 ,0 .913 and 0 .675 for S≥S3 ,0 .891 and 0 .709 for S≥S4 ,respectively . Conclusions The ZSI and APRI all could be used to evaluate the stage of liver fibrosis ,but the ZSI index is superior to APRI in assessing the stage of liver fibrosis . SVQ could provide object and accurate image ,the quantitative analysis of tissue could timely and accurately evaluate the severity of liver fibrosis .

Objective To estimate the impact of the image quality of conebeam CT on the accelerator for the Bowtie filter. Methods This study used the system of conebeam CT on the accelerator,and scaned the phantom of Catphan 500 in the multiplicate scanning conditions with and without the Bowtie filter. The scanning conditions were : voltage :120 kV, 100 kV, 80 kV, electricity:25 mA, 40 mA, 64 mA,time of exposure :40 MHz, collimator: M20, L20, scanning angle :358°. We transmitted the scanning data in the treatment planning systems of Philips Pinnacle 8. 0, and estimated the influence of the image quality.Results With and without the Bowtie filter, all of the images had high geometric precision, and the maximum difference of the nominal and actual distance at the horizontal, vertical and arrowy directions in the transection were 0. 50% and 0. 56% ( t = 0. 44, P ＞ 0. 05 ), 0. 44% and 0. 48% ( t = 1.01, P ＞ 0. 05 ),0. 50% and 0. 56% (t = 1.06,P ＞0. 05 ), respectively. The spatial resolution was 0. 167 cm, immutably.The ununiformity with the Bowtie filter was decreased of 28.0% -76.0% (t=2.53,P＜0. 05)、2.8%-50.0% (t= 3.02,P＜0.01 ) than those without the Bowtie filter, and the contrast-to-noise ratio was increased of 4.0% -41.6% (t=2.70,P＜0.05)、4.0% -50.0% (t=2.14,P＜0.05), using the collimators of M20 and L20, respectively. The Bowtie filter could display clearly the edge of scanning phantom, and improve the CT number of the image edge of phantom. And the linearity of CT number was also improved. Couclusions With the Bowtie filter, the image uniformity, the precision and linearity of CT number and the contrast-to-noise ratio were improved obviously, the edge artifacts were decreased, and the geometric precision and the spacial resolution did not change.
