ObjectiveTo observe the curative effect of temporal orbicularis oculi muscle transposition surgery for senile lower eyelid entropion. MethodsSeventy-eight patients including 93 eyes of senile lower eyelid entropion were treated with temporal orbicularis oculi muscle turn surgical treatment between May 2009 and January 2015. Six months after the operation, the rectification was evaluated. ResultsA total of 67 cases (72 eyes) finished the follow-up observation, among which 49 (51 eyes) had a good effect, 18 (21 eyes) had general effect, and 0 (0 eyes) had poor effect. No patients had such complications as infection or eyelid deformity. All the patients' corneal epithelial cell loss was cured after surgery. The skin of lower eyelid of these 67 cases (72 eyes) were raised to various degrees. ConclusionThe orbicularis oculi muscle temporal transposition surgery for the treatment of senile entropion can fulfill both clinical treatment and aesthetic need, and will prevent recurrence in a certain period.
Objective To investigate the CT imaging features of pancreatic fatty replacement and its clinical significance. Methods Three patients with pancreatic fatty replacement detected by CT were retrospectively analyzed. CT examination included plain scan and contrast-enhanced scanning at the arterial and portal venous phases. The shape, size, density, pancreatic lobulation and interlobular spaces, course of the pancreatic duct were carefully observed. The clinic and laboratory data were also analyzed to determine the clinical significance of pancreatic fatty replacement. Results ①Imaging features: Two patients had complete fatty replacement involving the entire pancreas, another one had most fatty replacement sparing the posterior aspect of head and tail. Two patients had regular configuration of pancreas. The size of pancreas was slightly enlarged in 2 patients. Lobular atrophy and widening of interlobular spaces were present in all 3 patients. The pancreatic duct was normal in 3 patients. ②Clinic findings: Chronic diarrhea was present in 3 patients. Two patiens had diabetes （one had chronic cholangitis with choledochal lithiasis）， another one had small stone in the common bile duct. Serum lipase was low in 3 patients, of which one had low serum amylase. Conclusion Pancreatic fatty replacement demonstrates certain characteristic CT appearances, and is usually associated with disturbances of both the endocrine and exocrine functions of the pancreas.
Objective To investigate the CT imaging features of autoimmune pancreatitis (AIP) with report of 4 cases and literature review. Methods The CT imaging data of 4 AIP patients proved on the basis of clinical findings, laboratory tests, response to steroids therapy and follow-up observation were retrospectively collected. Plain CT and contrast-enhanced dual phase CT scan at arterial and portal venous phases were performed for all 4 patients. All imaging data were reviewed, focusing on the shape, size, parenchyma density and enhancement patterns of the pancreas, as well as the biliary and pancreatic ducts, peripancreatic fat, blood vessels, retroperitoneal spaces, lymph nodes, and other positive findings. Results Three patients showed diffuse swelling of the pancreas on CT and 1 had focal enlargement of pancreatic head. Swelled pancreas was hypodense on plain CT images, showed decreased enhancement on artery phase and moderate enhancement on portal venous phase images of contrast-enhanced CT. Capsule-like enhanced rim was found around swelled pancreas in 2 patients. Stricture of distal common bile duct was present in 2 patients, and ERCP showed irregular narrowing of the main pancreatic duct in 1 cases. After steroid therapy, all patients showed significant morphological improvement of the pancreas at follow-up CT examination. Conclusion CT scan reveals certain characteristic imaging findings of AIP, thus it is helpful for the diagnosis of AIP.
ObjectiveTo investigate the MRI manifestations of internal carotid artery dissection (ICAD) before and after treatment. MethodsMRI materials of 20 patients with ICAD between November 2007 and February 2013 were collected for analysis. ResultsMRI manifestations of ICAD showed 17 cases of artery stenosis, 16 cases of mural hematoma or thrombus, 3 cases of aneurysmal dilatation, and 2 cases of lines of intimal flap. The treatment outcome MRI manifestations showed that 18 patients had effective response, including disappeared (n=9) and lessened (n=8) artery stenosis, disappeared (n=13) and diminished (n=3) hematoma and thrombus, and shrunken aneurysmal dilatation (n=1); and there were 2 cases of unchanged aneurysmal dilatation, and another 2 patients had aneurysmal dilatation while stenosis lessened. ConclusionMRI manifestations of internal carotid artery dissection mainly include stenosis, mural hematoma or thrombus, and aneurysmal dilatation. Stenosis, mural hematoma or thrombus usually disappear and lessen in the treatment, and all MRI findings may vary among each other.
【Abstract】ObjectiveTo investigate the value of volumetric interpolated breathhold examination (3DVIBE) MRI sequence in the diagnosis of functional islet cell tumors of the pancreas. MethodsDedicated MRI scan was performed for 3 patients suspected to have functional islet cell tumors of the pancreas on clinical and laboratory basis. The MRI scan protocol included routine axial T1W and T2W, coronal true fast imaging with steady state procession (TrueFISP) and MRCP, gadoliniumenhanced 3DVIBE dynamic triphasic acquisitions and enhanced 2D GRE T1W scan. The three phases images of 3DVIBE sequence were acquired at 15 s, 40 s and 65 s after injection of contrast agent, corresponding to the early arterial, late arterial and portal venous phase respectively. The imaging features were compared with surgical and pathological findings. ResultsThe triphasic images of 3DVIBE sequence depicted clearly the morphology of small functional islet cell tumors of the pancreas and reflected accurately the characteristics of tumor blood supply, while other MRI sequences might miss these small lesions. ConclusionThinslice and fast dynamic MRI sequence, as exemplified by 3DVIBE sequence, is very useful in the detection and characterization of pancreatic functional islet cell tumors.

Objective To investigate the value of multislice spiral CT （MSCT） findings in the diagnosis of hepatic tuberculosis. Methods MSCT imaging data, including both plain and contrast-enhanced CT scan, of 14 patients with hepatic tuberculosis confirmed by surgery (5 patients), aspiration biopsy (4 patients), or clinic follow-up (5 patients) were collected for the study. MSCT findings were analyzed with correlation of pathological changes. Results Hepatic tuberculosis was classified into 2 types. ①The parenchymal type (12 patients), which was further divided into 4 subtypes: Miliary subtype (2 patients) showed multiple tiny hypodense dots with faint border and had no enhancement; Nodular subtype (5 patients) showed blurring border on plain CT scan, 2 patients had no enhancement, 2 had peripheral rim-like enhancement, and peripheral rim enhancement mixed with no enhancement in 1 patient; Abscess subtype (4 patients) showed central hypodense area with peripheral zone-like enhancement in 2 patients, or patchy like slight enhancement in 2 patients; Fabric and calcific subtype (1 patient) depicted enplaque calcification. ②The serohepatic type (2 patients) showed thickened hepatic capsule, sub-capsule nodules with slight enhancement, and local subcapsular fluid collection. Other signs included hepatomegaly, tuberculous lymphadenopathy, splenic tuberculosis, and tuberculosis of pancreas, adrenal glands, intestine and thorax. Conclusion MSCT plays an important role in diagnosis of hepatic tuberculosis, by reflecting underlying pathological changes.
ObjectiveTo explore the practice effect of the combination management of tertiary hospital and community hospital for home peritoneal dialysis patients. MethodsA total of 50 patients of end-stage renal disease from December 2012 to May 2013 were involved in this study, including 26 males, and 24 females with the average age of 47.1±13.9. The patients were randomly divided into hospital group (30 patients) and combination group (20 patients). For the patients in the hospital group, the specialists take care of them with regular outpatient service and follow-up; for the patients in the combination group, they were taken care by doctors from both tertiary hospital and community hospital, while the community general practitioners were trained by the tertiary hospital regularly with peritoneal dialysis basic treatment and standardization management and communication. All the patients were managed for 9 months. ResultsAt the end of the observation,the dialysis adequacy success rate, hemoglobin, blood potassium, phosphorus, calcium, albumin, CO2CP, blood pressure success rate, the incidence of peritonitis, and average monthly medical treatment expense between the two groups were not statistically different (P>0.05); the difference in cost of transportation was statistically significant (P<0.05). ConclusionThe standardization manage of combination of tertiary hospital and community for patients with home peritoneal dialysis may reduces the patients' expense in transportation, and improve the community general practitioners' level of basic knowledge and indication of peritoneal dialysis.
