Objective Acute pancreatitis exhibits different clinical and ultrasonic features in patients complicated with acute acalculous cholecystitis ( AAC) at different stages .The aim of this study was to analyze the ultrasonic characteristics of acute pancreati-tis complicated with AAC at different stages . Methods We retrospectively analyzed the clinical data about 41 cases of acute pancrea-titis with moderate to severe AAC .According to whether AAC developed within or after 2 weeks of the onset of acute pancreatitis , we divided the patients into an early-stage group (n=18) and a late-stage group (n=23).We recorded the gallbladder size, gallbladder wall thickness , fluid around the gallbladder , biliary sludge deposition and the Murphy′s sign by ultrasonography , obtained AAC-related clinical and laboratory data concerning body temperature , Murphy′s sign, WBC count and C-reactive protein level , and analyzed the ultrasonic features of AAC at different stages in the acute pancreatitis patients. Results All the patients experienced a fever of >38.5℃, 38.89%with chills in the early onset group and 47.83%in the late onset group .Increases were observed in patients of the early-and late-stage groups in the WBC count ( 94.44%vs 82.61%) , the C-reactive protein level ( 100%vs 91.30%) , and the fluid volume around the gallbladder (94.44%vs 60.86%, P<0.05), but incidence rate of gallbladder wall thickening was significantly lower in the former than in the latter group (11.11%vs 78.26%, P<0.01). Conclusion AAC developing at different stages of acute pancreatitis has different ultrasonic features , with higher incidence rates of fluid around the gallbladder in the early stage and gallbladder wall thickening in the late stage.

This study was aimed to diffuse the lung and promote urination for the observation of cardiopulmonary re-lated index change of cor pulmonale rats to further explore the treatment effect on the pulmonary function, pulmonary arterial hypertension (PAH) and the influence of right heart hypertrophy of rats, in order to further illustrate the ef-fect of diffusing the lung and promoting urination for cor pulmonale. Sixty Wistar rats were randomly divided into the control group, model group and Xiao-Qing-Long decoction (XQLD) group with 20 rats in each group. The AniRes2003 animal lung function analysis system was applied to measure the pulmonary function of rats. And the multi-guide physiological recorder was used in the recording of the pulmonary artery pressure of rats. The conven-tional weighing method was applied to calculate and obtain the change of right heart hypertrophy. The results showed that compared to the control group, symptoms in the model group became severe obviously, which include reduced activity, slow movement and occasional airway sputum sound, and the right heart hypertrophy index of the model group increased obviously (P < 0.01). Compared to the model group, the pulmonary function and pulmonary artery pressure of the XQLD group have obvious difference (P< 0.05). It was concluded that to diffuse the lung and pro-mote urination can effectively improve the pulmonary function, PAH and the right heart hypertrophy index of rats with cor pulmonale (fluid retention). The effect of this method is definite in the treatment of cor pulmonale.

OBJECTIVETo identify the correlation of the volume of residual urine (VRU) with the severity of bladder outlet obstruction (BOO) and detrusor contractility in patients with benign prostatic hyperplasia (BPH).

METHODSA total of 152 patients with clinically diagnosed BPH underwent ultrasonography for measurement of the prostate volume and RVU, free uroflowmetry, and urodynamic examination for the severity of BOO and detrusor contractility. Using the software SPSS20. 0, we analyzed the correlation between the ultrasonographic results and urodynamic parameters and compared the two sample means by the t-test.

RESULTSThe prostate volume was correlated positively with BOO severity (r = 0.432, P < 0.01) and detrusor contractility (r = 0.343 , P < 0.01) while Qmax negatively with BOO severity (r = 0.327, P < 0.01) but not significantly with detrusor contractility (r = 0.123, P > 0.05). VRU showed a significantly negative correlation with detrusor contractility when > 150 ml (r = -0.490, P < 0.01), even more significantly when > 300 ml (r = -0.717, P < 0.01), but exhibited no significant correlation with it when ≤ 150 ml (r = 0.041, P > 0.05).

CONCLUSIONVRU can somehow predict the detrusor function. For patients with VRU > 150 ml, especially for those with VRU > 300 ml, the detrusor function should be evaluated and urodynamic examination is recommended for exact assessment of BOO severity and detrusor contractility.

Objectlve To explore the effect of Qibai Pingfei capsule on the right ventricular hypertrophy index (RVHI)of rats with phlegm and blood stasis of COPD.Methods 60 rats were randomly divided into 6 groups,a control group,a model group,a Ligustrazine group,a Nifedipine group,a high dose Qibai Pingfei capsule group and a low dose Qibai Pingfei capsule group.Composite factors method was adopted to establish phlegm and blood stasis COPD rat model.At the same time of modeling.Qibai Pingfei capsule,Ligustrazine,Nifedipine were also given to these rats.Observed the changes of RVHI in each group.Results RVHI did not show statistic difierence between high dose of the Qibai Pingfei capsule group and the control group(P＞0.05).and between the Nifedipine group and the model group(P＞0.05).RVHI manifested significant diffbrencc between the Ligustrazine group and the low dose Qibai Pingfei capsule group(P＜0.01),and between the Ligustrazine group and the control group(P＜0.01).Conclusion High dose Qibai Pingfei capsule can effectively prevent the right ventricular hypertrophy of model rats with the phlegm and blood stasis of COPD.Ligustrazine has certain effects but not as good as high dose Qibai Pingfei capsule.Nifedipine can not prevent the right ventricular hypertrophy of model rats.

Objective To investigate the mechanism and significance of low concentration nitric oxide (NO) inhalation in the treatment of pulmonary thromboembelism in swine. Method The pulmonary thromboem-bolism(PTE) model was made in 15 healthy infantile swines which were subsequently assigned to either control group (n = 8) or NO group (n = 7). Swines of the control group were not treated with any medicine, while 10 ppm of NO was administered by continuous inhalation for 2 hours to swines of NO group. Volume of physiological dead space (VDphy), volume of alveolar dead space (VDalv), intrapulmonary shunt (Qs/Qt), mean pulmonary arterial pressure (PAP), systolic blood pressure (SBP), heart rate (HR), cardiac output (CO), arterial blood pH (pH), arterial partial pressure of carbon dioxide (PaCO2) and arterial partial pressure of oxygen (PaO2) were measured 30 min before and 0 min, 30 min, 60 min, 120 min and 180 min after establishment of VIE. Results The post-FIE VDphy, VDalv, Qs/Qt and PAP in both groups increased markedly after PTE compared with the cor-responding pre-PTE measurements (P < 0.01). Post-FIE PaO2 of both groups decreased significandy (P <0.05 and P <0.01), while significance difference was found between pre- and post-PTE HR, SBP, CO, pH or PaCO2 in neither groups (P > 0.05). Both post-PTE PAP and VDalv in NO group were markedly lower(P <0.05 and P <0.01) and beth PaCO2 and PaO2 were much higher than those of the control group (P <0.05). No signi-fieant difference were found in other measurements between two groups. Conclusions Pulmonary arterial pressure may be lowered, alveoli dead space may be reduced and PaCO2 increased by low concentration NO inhalation for the treatment of PIE without decline in haemodynamic status.

Objective To investigate the mechanism and significance of low density nitric oxide (NO) in-halation combined with urokinase (UK) in treatment of pulmonary thromboembolism in swine. Method PIE model was estabhshed in 12 healthy infant swines, which were subsequently assigned to UK group or UK+NO ter establishment of the PIE model;in the UK+NO group, swines received continuous NO inhalation of 10 ppm NO for two hours in addition to administration of UK no done in the UK+NO group. Volume of physiological dead space (VDphy), volume of alveolar dead space (VDalv), intrapoulmonary shunt (Qs/Qt), mean ptdmonary arteri-al pressure (PAP), systolic blood pressure (SBP), heart rote (HR), cardiac output (CO), arterial blood pH val-ue, arterial partial pressure of carbon dioxide (PaCO2) and arterial partial pressure of oxygen (PaO2) were mea-sured at 30 min before and 0 min, 30 min, 60 rain, 120 min and 180min after establishment of pulmonary em-bolism.All date were analyzed by ANOVA (SNK-q test),and P<0.05 was considered as significantly differet. Results After PE, VDphy, VDalv, Qs/Qt and PAP of both groups increased markedly compared with the pre-PE values (P<0.01), but the post-PE PAP showed a tendency of decline as time passed. Post-PE PaO2 of both groups decreased significantly (P<0.05 and P<0.01). There were no significant differences in HR, SBP, CO, pH or PaCO2 between pre-PE and post-PE (P>0.05). Both pre- and Post-PE PAP of UK+NO group were markedly less than those of the UK group (P<0.05 and P<0.01). No significant difference was found in other measurements between the two groups. Conclusions UK combined with low density NO inhalation may lower pul-monary arterial pressure promptly to alleviate PIE without distur bance in hemodynamics or gas exchange status and without pulmonary raterial pressure rebound.
