To investigate the relationship of body mass index and non-alcoholic fatty liver disease (NAFLD) in patients with type 2 diabetes mellitus. Three hundred and eleven patients with type 2 diabetes mellitus diagnosed according WHO 1999 consensus criteria and 366 healthy subjects were enrolled in the study. Medical history was acquired and physical examination was conducted, and blood sugar, liver and kidney functions, lipid profile and abdominal ultrasonography color were examined. Sixty seven out of 366 healthy subjects were confirmed to have non-alcoholic fatty liver disease (NAFLD) ,including 51 mild case ( 13.9％ ) ,15 moderate cases(4. 1％ ) and 1 severe case(0. 3％ ) ; while in 311 diabetic patients NAFLD was detected in 144 cases, including 85 mild cases (27.3％) ,53 moderate cases( 17.3％ )and 19 severe cases( 1.9％ ). The prevalence rate of NAFLD was higher in diabetic patients than control group in BMI ＜ 23.0 kg/m2 group, 23.0 -24. 9 kg/m2 group and 25.0 -29. 9 kg/m2 group(P ＜0. 01 ) ; however, there was no difference between two groups when BMi ≥30 kg/m2 (P ＞0. 05 ). The prevalence of NAFLD increased with BMI whether in control group or in diabetic group, especially when BMI ＞ 25 kg/m2. In addition to the prevalence of NAFLD, metabolic syndrome increased with BMI in diabetic patients. These findings indicate that type 2 diabetic patients have a high prevalence of NAFLD, especially in obese patients.

Objective To explore the therapeutic effect of different postoperative chemotherapy and administration pathways in primary hepatocellular carcinoma (PHC) patients with portal vein tumor thrombus (PVTT). Methods 60 PHC patients with PVTT were divided into A, B, C and D groups. A group was treated by transcatheter arterial chemo-embolization (TACE); B group was treated by TACE and portal vein intubation(PVI) with quick intravenous injection; C group was treated by TACE and PVI with slow infusion controlled by computer; and D group was treated by hepatic arterial intubation chemo-embolization (HAI) and PVI with slow infusion controlled by computer. Results The survival rate among groups A, B and C had a significant difference (P0.05). Conclusion PHC patients with PVTT could be treated by both hepatic arterial chemotherapy and portal vein chemotherapy throug portal vein continuous infusion. TACE or HAI was suitable for postoperative chemotherapy.

Objective To analyze the common reasons for misdiagnosis of atypical pulmonary embolism (APE) ,and to im‐prove the identification of APE .Methods The risk factors ,clinical manifestations ,laboratory examinations and radiographic data of 120 cases of APE diagnosed from January 2006 to December 2013 in the department of cardiovascular medicine and respiratory medicine of Xinqiao Hospital and the Affiliated Hospital of Luzhou Medical College were studied retrospectively .Results Among those 120 cases of APE ,39 cases were misdiagnosed on admission (32 .5% ) .8 cases were misdiagnosed as acute coronary syn‐drome ,7 cases as stable angina pectoris ,7 cases as chronic cor pulmonale ,5 cases as pneumonia ,3 cases as pleural effusion ,3 cases as tuberculosis ,3 cases as asthma ,1 case as atrial septal defect ,1 case as acute heart failure ,and 1 case as cardiogenic syncope .Con‐clusion APE is easy to be misdiagnosed for its non‐specific clinical manifestation .Pulmonary enhanced CT or CTPA should be car‐ried out in time for those highly suspected patients ,in order to reduce the misdiagnosis of APE .

Objective To investigate the diagnostic value of Multislice CT scanning in patients with acute thoracic trauma. Methods151 patients with chest wound admitted after Multislice CT scanning were reviewed and analyzed. ResultsThis group of 151 patients with chest wound after X-ray and CT inspection were as follows:lungs were damaged in 139 cases including 52 cases with traumatic wet lung,94 cases with lung rip,28 cases with lacerated wound and 7 cases with tracheal bronchial tube damage.Damages outside the lungs were found in 108 patients including 83 patients with trauma in pleural membrane(hemothorax 27 cases,pneumothorax 32 cases and blood pneumothorax 24 cases),mediastinum damage in 9 cases(vertical mediastinal pneumatosis 6 cases,hematocele 4 cases and traumatic disphragmatic hernia 2 cases),thoracic wall damage in 76 cases(rib bone fracture 59 cases,breast bone fracture 18 cases and costal cartilages damage 5 cases).Clavicle and scapula fracture in 31 cases. ConclusionMultislice CT scanning was principal method for the diagnosis of chest wound,it had the advantages of scanning range,quick scanning and characteristics of high sensitivity,and it would certainly play a vital role in first aid process in emergency medical treatment of wound.

Objective Revascularization of the distal segment of the anterior cerebral artery (ACA) using extracranial donors requires long interposition grafts.A novel bypass procedure which uses the two main branches of the superficial temporal artery (STA) to reach the A3 segment of the anterior cerebral artery with a single skin incision was designed.Methods Ten cadaveric specimens were dissected through a single skin incision to harvest the frontal and parietal branches of the STA from June,2017 to September,2017.An anterior interhemispheric approach provided access to the middle internal frontal artery (MIFA).The parietal STA was used as an interposition graft between the frontal STA and MIFA.Lengths and calibers of the distal branches of STA and MIFA were measured at the anastomotic sites.All data was statistical analysis by t-test.Results The average caliber of MIFA was (1.4±0.2) mm,which matched the caliber of both frontal and parietal branches of STA.The mean distance for an end-to-side bypass from STA to MIFA was (144.5±7.4) mm and the average harvested donor-graft complex length was (203.1±27.9) mm.This bypass construct provided around 140％ donor graft length.Conclusion Using the parietal branch of the STA as an interposition graft enabled a successful tension-free STA-MIFA bypass.The advantages of this technique over existing approaches include sufficient graft length,caliber match and relative technical ease.
