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.

AIM: To explore the effects of chromodomain protein 8 (CBX8) on the proliferation and apoptosis of human glioma cells.METHODS: The expression of CBX8 in the tissues and cells was detected by Western blot and RT-qPCR.The overexpression (Flag-CBX8) and silencing (sh-CBX8) vectors of CBX8 were constructed and transfected into glioma T98G cells and U87MG cells.The cell proliferation was detected by MTT assay and BrdU staining.The cell apoptosis was analyzed by flow cytometry.The protein expression of Rb/E2F1 was detected by Western blot.RESULTS: Compared with normal brain tissues and astrocytes, the expression of CBX8 was increased in the glioma tissues and glioma cells.Overexpression of CBX8 promoted the cell proliferation, inhibited the cell apoptosis, and upregulated the protein levels of Rb/E2F1.On the contrary, silencing of CBX8 inhibited the cell proliferation, promoted the cell apoptosis, and decreased the protein levels of Rb/E2F1 in the T98G cells and U87MG cells.Moreover, the expression of cyclin D1 and Bcl-2/Bax ratio were reduced after transfection with sh-E2F1 in the T98G cells and U87MG cells.CONCLUSION: CBX8 may regulate the proliferation and apoptosis of glioma cells through Rb/E2F1 pathway.

Genotypes of estrogen receptor gene (ER) α and β in 110 patients with non-alcoholic fatty liver disease (NAFLD) and 100 control subjects were examined by polymerase chain reaction-based restriction fragment length polymorphism.The haplotype analysis was conducted by SHEsis on-line computing platform.The results showed that there were no differences in the genotype frequencies and allele frequencies of ERα at Xba Ⅰ and Pvu Ⅱ enzyme cutting sites between two groups (P ＞ 0.05).There existed significant differences in the genotype frequencies and allele frequencies of ERβ at Rsa Ⅰ and Alu Ⅰ enzyme cutting sites between these two groups (P ＜ 0.05 or P ＜0.01).The risk of NAFLD in postmenopausal women with R or a allele was 1.833 (95％ CI1.209-2.779,P＜0.05)or 1.782 (95％ CI 1.037-3.061,P＜0.05) fold of that with allele r or A.The frequency of r-A haplotype in ERβ was significantly lower in NAFLD group than that in control group (OR =0.529,95％ CI 0.348-0.805).Logistic regression analysis showed the relationship of fasting blood glucose,triglyceride,body mass index,diastolic pressure,Alu Ⅰ genotype with NAFLD (all P＜0.01).The risk of NAFLD in postmenopausal women with Aa/aa genotype was 1.345 (95％ CI 1.028-2.505,P＜0.05) folds of that with AA genotype.

Objective To investigate the diagnostic value of combined detection of serum gastrin-releasing peptide precursor (ProGRP),neuron specific enolization enzyme(NSE)and carcinoembryonicantigen(CEA)in small cell lung cancer(SCLC). Methods 471 patients with lung tumor from department of respiratory medicine and thoracic surgery and 162 healthy people from medical examination center were studied.Serum levels of ProGRP,NSE and CEA were detected by using electrochemi-cal luminescence method.ROC curves were drawn and the area under the curve (AUC)was calculated.Results The levels of ProGRP and NSE were significantly higher in patients with SCLC than those in NSCLC,lung benign disease group and normal control group (P <0.01).The levels of CEA were significantly higher in SCLC than those in patients with lung be-nign disease group and normal control group (P <0.05).The AUC of ProGRP,NSE and CEA in the diagnosis of SCLC were 0.933,0.777 and 0.554,respectively.The sensitivity of ProGRP,NSE and CEA in the diagnosis of SCLC were 82.6%,60.4%,41.6% and the specificity were 95.2%,83.3% and 71.7% respectively.The sensitivity of combined detec-tion of ProGRP,NSE and CEA was 91.3% and the specificity was 65.3%.Conclusion The serum ProGRP detection has a higher diagnostic value for SCLC.The combined detection of ProGRP,NSE and CEA is useful in the early diagnosis of SCLC.

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.

Objective To explore the clinicopathological features,imaging manifestation and treatment of solitary fibrous tumor in the central nervous system(cSFT),in order to improve the diagnosis and treatment.Methods Fourteen cases of cSFT that had been received microsurgery treatment from June,2010 to July,2016 were analyzed retrospectively.The clinicopathological features,treatment and prognosis were concluded and analyzed.Results In 14 patients with cSFT treated with microsurgery,and 1 case in the foramen magnum region for the first time,and enriched the understanding of this disease.Of 14 patients with cSFT,12 received total resection and 2 subtotal or part.The cSFT were pathologically diagnosed as benign tumors in 11 patients and low grade cSFT in 3.The microscopical presence of spindle-shaped tumor cells arranged in fascicles that alternate hypocellular and hypercellular areas separated from each other by collagenous fibre.Immunohistochemistry was positive for Vimentin,and CD34,Bcl-2 of 14 patients,and positive for CD99 in 12 patients.Followed-up time was from 6 to 49 months.Twelve cases had good prognosis to total resection and 2 recurrence due to subtotal or part resection.Conclusion cSFT is extremely rare,and it has some characteristics on MRI,final diagnosis should be depended on pathological and immunohistochemical examination.There are good prognoses in the patients with cSFT after the total removal of cSFT,but when the lesion could not be totally resected,radiotherapy should be considered,the curative effect of chemotherapy on cSFT is not definitive.

Objective To explore the feasibility of occipital artery(OA) to anterior inferior cerebellar artery (AICA) through the extended retrosigmoid approach,also perform a systemic microanatomical study of OA and AICA with the exposure of extended retrosigmoid approach,find the easy way to perform the procedure.Methods From September,2016 to January,2017,5 adult cadaveric heads injected with colored latex (total 10 sides) were performed the extended retrosigmoid approach,and measured the caliber of distal occipital artery (OA),the final length of the OA harvest,the reliable landmark of the OA harvest,and the distance from the flocculonodular segment of anterior inferior cerebellar artery (AICA) to the OA,the diameter of AICA flocculonodular segment branch.Whole procedure of OA to IACA bypass also be performed.Statistical analysis was performed.Results By the extended retrosigmoid approach,AICA flocculonodular segment could be easily exposure,the average diameter was 1.2 mm,the OA branch could be harvested in average was (72.3±3.3)mm in length from the occipital sulcus,and the average distance between occipital sulcus and AICA flocculonodular segment was (47.6±l.9)mm.The bypass procedure also could be performed through the proper corridor.Conclusion The Extended retrosigmoid approach is a safe and efficient way to perform the OA-AICA bypass procedure,and the procedure is easier to be performed than other surgical approaches.
