Objective To explore the diagnostic value of endoscopic retrograde cholangio-pancreatiography (ERCP),ultrasonography (US) and CT scanning on cholagio-pancreatic diseases caused by clonorchis sinensis infection.Methods The results of US,CF and ERCP examination in 65 cases of obstructive jaundice caused by clonorchiasis and confirmed by presence of imagoes or eggs in feces or bile juice were analyzed and compared retrospectively.Results US examination was the simplest and most convenient which was characterized by diffuse even dilatation,thickening of walls,strengthened echo with the shape of“equal sign”intrahepatic bile ducts.The characteristic findings of CT included saccular dilatation of bile ducts of the periphery of the liver,thickening of the walls of bile ducts.Under duodenoscopy,32.3% (21/65) of cases presented as abnormal papilla such as small opening,mucosa outward turned,trapping or stiffness.Alterations in ERCP were characterized by shm or oval filling defect,diffuse saccular dilatation of terminal intrahepatic bile ducts.The most common complications included cholangiolithiasis (40%,26/65),carcinoma of bile duct on papilla (9.8%,6/65),and pancreatitis (1.5%,1/ 65).Conclusions Three methods were all useful for diagnosis of cholangio-pancreatic diseases caused by clonorchis sinensis infection,which were identically characterized by diffuse saccular dilatation of terminal intrahepatic bile ducts.The gold standard of diagnosis was the presence of imagoes or eggs in bile juice aspirated by the route of ERCP.Endoscopic sphincterectomy with postoperative vermifugal was the first choice of the treatment.

Objective To discuss the diagnostic value of MRI for portal vein(PV)and superior mesenteric venous(SMV)thrombosis.Methods Twelve patients with portal vein and superior mesenterie venous thrombosis proved by operation and pathology were examined with T_1WI,T_2WI,T_2-weighted fat suppression imaging,MR angiography(MRA)and Gd-DTPA enhanced dynamic MRI.Results Signals in PV and SMV were detected on T_1 WI and T2WI in 12 cases;3 acute thrombus presented hypo-or isointense on T_1 WI and hyperintense on T_2 WI.ttyperintense on T_1 WI and T_2WI were showed in 8 subacute thrombus; 1 chronic thrombus presented heterogenous intense on T_1W1 and hypointense on T_2W1.No enhancement within PV and SMV was found on Gd-DTPA enhanced images.Bowel dilatation was found in 10 cases,bowel hemorrhage in 6,bowel wall thickening in 12,intestinal pneumatosis in 3,ascites in 12,cavernous transformation of the portal vein in 3,hepatic perfusion disorder in 6.Conclusion MRI is an important and sensitive imaging method for the diagnosis and location of portal vein and superior mesenteric venous thrombosis with intestinal ischemia.

Objective To knockout the MATP gene of mouse melanoma cell line B16F10 using CRISPR/Cas9 system,and to lay foundation for the functional study of MATP gene.Methods Specific primers of MATP were designed according to the report in http://crispr.mit.edu/ website.The primers were linked to pCAS9/gRNA1 vector.Then the positive vector was transfected into mouse melanoma B16F10 cells,and monoclonal cell lines were obtained by the infinite dilution method.After the genomes of different monoclonal cell lines were extracted and sequenced,the cell lines with MATP gene cleavage were screened,and the expression of MATP in these cell lines was verified by Western-blot analysis.Results Three MATP gene knockout cell lines were successfully obtained.The western-blot results showed that the cell lines did not express MATP protein.Conclusions The knockout of MATP gene in B16F10 cell line can be successfully achieved using the pCAS9/gRNA1 vector.

Objective To master iodine nutritional status of people after universal salt iodization in Xining that reached the stage goal of elimination iodine deficiency disorders. Methods In the 7 counties investigated of Xining in 2009, 5 towns were randomly selected in each county, and one school was randomly selected in each town, 80 children aged 8 to 10 were randomly selected in each school, and goiter were examined, urinary iodine and salt iodine were tested. Thyroid gland goiter of children was detected by thyroid palpation, children's urinary iodine was tested by As( Ⅲ )-Ce4+ catalytic spectrophotometry, and salt iodine was tested by direct titration. Results A total of 2919 children aged 8 to 10 were examined, 31 goiter was detected, goiter rate was 1.06%(31/2919).One thousand and seventy-eight urine samples were detected, urinary iodine median was 205.3 μg/L, that lower than 20 μg/L accounted for 1.9% (20/1078), lower than 50 μg/L accounted for 4.5%(48/1078). Two thousand and seventy-nine salt samples were detected, median of salt iodine was 32.80 mg/kg, the rate of non-iodized salt was 0.87%(18/2079), the coverage rate of iodized salt was 99.13%(2061/2079), the qualified rate of iodized salt was 98.64% (2033/2061), the consumption rate of qualified iodized salt was 97.79% (2033/2079). Conclusions Prevention and control of iodine deficiency disorders has achieved remarkable results in Xining city, all indicators have reached the national standard to eliminate iodine deficiency disorders.

Objective To study the clinical value of portable echocardiography system in diagnosis for acute paroxysmal dyspnea.Methods Clinical data of 81 patients with acute paroxysmal dyspnea recorded by a portable echocardiography apparatus at their bedside were retrospectively analyzed,and compared to those of 45 patients by conventional echocardiography.Results The 2D images in portable echocardiograph were similar to those of conventional echocardiograph.Diagnosis could be established in 74 (91.4%),corrected in six (7.4%) and not confirmed only in one (1.2%) of 81 patients with acute paroxysmal dyspnea by portable echocardiography system.And,portable echocardiography system could be used to diagnose pericardial effusion and to monitor perieardial puncturing and draining at bedside. Conclusions Portable echocardiography systems can provide rapid,accurate and valuable information on diagnosis and treatment for acute paroxysmal dyspnea,and make its clinical intervention accurate,scientific and effective,bringing echocardiography performed at bedside possible.

In this paper, we reviewed the brain imaging studies of male sexual function in recent years from three aspects: the brain mechanism of normal sexual function, the brain mechanism of sexual dysfunction, and the mechanism of drug therapy for sexual dysfunction. Studies show that the development stages of male sexual activities, such as the excitement phase, plateau phase and orgasm phase, are controlled by different neural networks. The mesodiencephalic transition zone may play an important role in the start up of male ejaculation. There are significant differences between sexual dysfunction males and normal males in activation patterns of the brain in sexual arousal. The medial orbitofrontal cortex and inferior frontal gyrus in the abnormal activation pattern are correlated with sexual dysfunction males in sexual arousal. Serum testosterone and morphine are commonly used drugs for male sexual dysfunction, whose mechanisms are to alter the activating levels of the medial orbitofrontal cortex, insula, claustrum and inferior temporal gyrus.

Objective To analyze the clinic-pathologic features of elderly myocardial infarction patients ( > 60 years) with and without left ventricular aneurysm formation.Methods Between January 1980 and October 2009,107 myocardial infarction patients were divided into aneurysm group (n =31 ) and non-aneurysm group ( n = 76) according to autopsy results and the clinic-pathologic features of the two groups were compared.Results Previous angina pectoris history was significantly less in aneurysm group than in non-aneurysm group [ 45.2% ( 14/31 ) vs.92.1% ( 70/76 ),P = 0.047 ].Incidence of hypertension was significantly higher in aneurysm group than in non-aneurysm group [ 77.4% (24/31) vs.36.8% (28/76),P = 0.033 ].The percentage of single-vessel disease [54.8% ( 17 /31 ) vs.23.7%(18/76),P =0.033] and the LAD disease [96.8% (30/31) vs.51.3% (39/76),P =0.048] were both significantly higher in aneurysm group than in non-aneurysm group.Heart failure and ventricular arrhythmias were more likely the cause of death in patients with aneurysm than patients without aneurysm [ 56.3% (18/31) vs.19.7% ( 15/76),P = 0.007 ].Aneurysm mostly located in left ventricular anterior wall and apex.Conclusions Our results suggest that patients with left ventricular aneurysm formation are more likely to have hypertension,single-vessel disease and LAD disease,heart failure and ventricular arrhythmias but less previous angina pectoris than patients without left ventricular aneurysm formation.The common locations of ventricular aneurvsm formation were left ventricular anterior wall and apex.
