Objective To observe the effect of acupressure to relieve the adverse effect of patients and success rate of intubation during gastric tube insertion. Methods We divided 90 pancreatitis patients into the observation group and the control group randomly with 45 cases in each group.Routine intubation method was used in the control group.While in the observation group we gave acupressure of Neiguan and Hegu point based in the routine method.Then we compared the changes in heart rate,bucking,nausea,vomiting and other adverse effect as well as the one-time success rate of intubation.Results Changes in heart rate before and after intubation in the control group were significantly different(P<0.05).The incidence rate of adverse effect in the control group was 51.1%and rate of repeated intubation was 26.7%.In the observation group changes in heart rate was not evident(P>0.05).The incidence rate of adverse effect in the observation group was 4.4%and the one-time success rate of intubation was 97.8%.Conclusion It proved effective to use acupressure of Neiguan and Hegu point during gastric intubation for gastrointestinal decompression.

Objective: To assess the accuracy of multi-slice spiral CT (MSCT) with imaging reconstruction in judging bronchial involvement from central lung cancer. Methods: MSCT was done in 30 patients who were diagnosed as central lung cancer. Images of bronchi related to lobectomy or pneumonectomy were reconstructed by means of imaging processing techniques. Then the relation between tumor and bronchus was assessed prospectively with both axial CT and CT with imaging reconstruction in comparison with subsequent pathologic and surgical findings. Results: All 30 patients underwent thoracotomy, lobectomy or pneumonectomy. Total 66 bronchi were studied. Compared with axial CT images, CT with imaging reconstruction was better in judging the relation of bronchus and tumor in comparison with subsequent pathologic and surgical findings (0.01

Objective To investigate characteristics of glucose metabolism of non-obese and obese women with polycystie ovary syndrome(PCOS).Methods From March 2008 to July 2011,118 PCOS patients were enrolled in this study and were divided into 53 cases (body mass index(BMI) ≥25 kg/m2) in obese group and 65 cases (BMI ＜ 25 kg/m2) in non-obese group.Participants' clinical data,glucose tolerance and insulin release test results were retrospectively reviewed.The prevalence of type 2 diabetes mellitus (T2DM),results of oral glucose tolerance test,impaired fasting glucose (IFG),impaired glucose tolerance (IGT) were compared between the two groups.Results (1) Blood glucose levels:at the time points of 30,60,120 and 180 minutes,the levels of fasting glucose were (5.2 ± 1.1),(8.5 ± 2.8),(8.1 ± 2.4),(6.3 ± 2.0) and (4.8 ± 1.5)mmol/L in non-obese group and(5.4 ±0.9),(9.1 ± 1.8),(9.3 ±0.6),(7.6 ± 1.0) and (5.4 ±0.8) mmol/L in obese group.Statistical difference was observed between obese and non-obese groups at each time point (t =-6.125,-4.005,-6.074,-6.751 and-4.512 respectively,P ＜0.01).(2) The level of insulin:at the time points of 30,60 and 120 min,the level of fasting insulin were (8 ± 4),(55 ± 21),(65 ± 14) and (45 ±18)mU/L in non-obese group and (13 ± 8),(85± 30),(105± 54) and (76 ± 46)mU/L in obese group.There were significant statistical difference between the two groups at each time point (t =-17.024,-12.540,-15.791 and-16.149 respectively,P ＜ 0.01).However,at the time point of 180 minutes,the level of insulin did not exhibit significant difference between obese and non-obese groups (P ＞ 0.05).(3) The prevalence of abnormal glucose metabolism:The rates of IGT were 13.85 ％ (9/65) in non-obese group and 24.53 ％ (13/53)in obese group,which also showed remarkable difference (x2 =18.446,P ＜ 0.01).The rates of T2DM were 1.54％ (1/65) in non-obese group and 7.55％ (4/53) in obese group,which reached significant difference (x2=16.005,P ＜ 0.01).Conclusion Abnormal glucose metabolism was observed more frequently in overweight or obese PCOS women.

Objective To evaluate the diagnostic value of CT by analyzing CT features of right-sided colon cancer.Methods CT findings of 35 cases with surgically proved right-sided colon cancer were analyzed retrospectively with regard to their pathologic features.Results 34 of 35(97.1%) were diagnosed accurately by CT . Of them , 29 cases (82.9%)were polypoid colon cancer , 6 cases were infiltrative colon cancer, 2 cases with typical “target sign”. 9 cases(25.7%) were found with pericolic infiltration during operation, 7 of 9 (77.8%) were detected by CT scan . Distal ileal involvement of 3 cases ( 8.6% ) were all detected by CT . Lymphadenopathy was showed in 11 (31.4%), 7 of 11(63.6%)were found by CT.Conclusion CT scan plays important role in diagnosis of right-sided colon cancer as well as in finding pericolic infiltration, distal ileal involvement and lymphadenopathy.

Objective To evaluate the efficacy of multislice helical CT(MSCT) in the diagnosis of coronary artery disease Methods 30 patients were studied with MSCT CT data were reconstructed to demonstrate the abnormalities of coronary artery and the results were compared with that of angiography Results In patients with heart rate less than 60 BPM, there was no difference to show the main branch of left coronary artery and left descending artery compared with more than 60 BPM( P =0 197 and 0 128,Fisher′exact);and obvious differences in showing left circumflex artery (? 2=5 88, P

Objective To present the multislice helical CT (MSCT) and chest radiographic findings of congenital bronchial atresia (CBA) in order to improve the diagnosis of CBA.Methods Eleven patients with CBA, who had histological results in 3 cases, bronchoscopy in 6 cases and more than 1 year follow-up in 2 cases, underwent MSCT with 10 mm slice thickness. 1.25 mm thickness images with 1 mm reconstruction interval were performed on 16-slice helical CT, and multiplanar reconstruction (MPR), maximum intensity projection (MIP) and minimum intensity projection (MinIP) were made at a dedicated workstation. The involved segment of lung, shape of bronchocele and hyperinflation around bronchocele were recorded. Results On CT findings, all 11 patients demonstrated bronchocele and peripheral emphysematous changes which were shown in 8 cases on chest radiographs. An air-fluid level within the bronchocele was seen in 3 cases by MSCT and 2 by chest radiographs. The segmental bronchus was affected in 10 cases and the subsegmental in 1 case. 3 CBAs were in the left and 8 in the right. 6 patients with CBA presented a rounded, branching opacity emanating from the hilum and 5 were seen as a peripheral nodule. Conclusion The presence of a bronchocele and surrouding emphysematous change is the typical radiologic finding of CBA. MSCT can provide more information than X-ray chest radiograph for the diagnosis of CBA.

Objective To demonstrate the origin of the right inferior phrenic artery(RIPA) in normal and hepatocellular carcinoma(HCC) patients and provide valuable anatomical information for angiographers before and after transcatheter arterial chemoembolization(TACE).Methods Four hundred and forty consecutive patients including 133 HCC cases who had biphase abdominal CT were assessed in this study.The routine abdominal enhanced CT scan(GE,LightSpeed16) was performed with 120 kV,200—240 mAs,10 mm collimation,1.375 pitch,and 10 mm reconstruction interval at 22—25 seconds for arterial phase triggered by timing bolus,60 seconds for portal venous phase after injection of 100 ml contrast material(300 mg I/ml) at a rate of 3.5 ml/s.Multiplanar reconstruction(MPR) and maximum intensity projection(MIP) images were generated using 1.25 mm images reconstructed with 1 mm interval in arterial phase and reviewed by two radiologists.An enhanced artery medial-posterior to the IVC,originated from aorta or its branches to the diaphragmatic dome was interpreted as the RIPA.Results The RIPA was showed in all(440 patients)(100%).Among 218(49.5%) RIPAs originated from the aorta,140 were from the right side of the aorta,22 from the left side of the aorta,56 from the anterior wall of the aorta,36 RIPAs had the same origin with the left inferior phrenic artery.Among 138(31.4%) RIPAs from the celiac artery,10 RIPAs had the same origin with the left gastric artery,and 33 RIPAs had the same origin with the left inferior phrenic artery.78(17.7%) were from the right renal artery,6(1.4%) were from the left gastric artery(the left gastric artery from aorta).The dilatation of the RIPA was demonstrated in 16 of(133 hepatocellular) carcinoma patients.Conclusion Multislice helical CT could demonstrate the origin of the RIPA in arterial phase and provide useful anatomical information for angiographer before and after TACE.
