Objective To explore effects and mechanism of inactivation of vitamin D receptor (VDR) in intestinal tumor growth of APCmin/+ mice. Methods To generate APCmin/+VDR -/- mice through breeding, the number and size of small intestinal and colonic tumors were assessed and compared between APCmin/+ and APCmin/+ VDR -/- mice. The intestinal tumors were diagnosed with HE stain. The expressions of BCL-2,vimentin-1,Stat-1 and MSH-2 proteins of tumors were determined by immanohistocbemistry and compared be-tween APCmin/+ and APCmin/+VDR -/- mice. Results A comparison between APCmin/+ and APCmin/+ VDR -/- mice revealed that the number of the tumors, which were larger than 3mm, was significantly increased in APCmin/+ VDR -/- mice at 4 months of age (P< 0.01). HE staining indicated fistulous adenomas from small intestine and colon of two groups, Immunostaining showed Stat - 1 level in APC-min/+ tumors were increased and MSH-2 and vimentin-1 levels in APCmin/+ VDR-/- mice were increased, compared to APCmin/+tumors. Conclusion These observations suggested that inactivation of VDR promoted the intestinal tumor growth of APCmin/+ mice.

AIM:To compare the synthesis efficiency of n3 and n6 very long chain polyunsaturated fatty acid ( VLC-PUFA ) by overexpressing ELOVL4 protein, providing guidance for treating Stargardt-like macular dystrophy (STGD3).
METHODS:To establish recombinant adenovirus with the ELOVL4 protein and green fluorescent protein, transferred into cultured PC12 cells. The cells were divided into 3 groups: PC12, PC12 + Ad- GFP and PC12 + Ad-ELOVL4, former two groups serve as controls. ELOVL4 gene expression was quantified by qRT-PCRs. ELOVL4 protein was analyzed by Western - Blot ( WB ) . The transduced cells were treated with both EPA and AA (1:1). After 48h of incubation, cells were collected, total lipids extracted and fatty acid methyl esters prepared and analyzed by gas chromatography-mass spectrometry ( GC-MS) .
RESULTS:When supplemented together, 20:5n3 (EPA) and 20:4n6 ( AA) were efficiently taken up at almost the same amounts in the PC12 cells regardless of ELOVL4 expression. The ELOVL4-expressing cells elongated both EPA and AA to a series of n3 and n6 VLC-PUFAs. From 20:5n3/EPA, 34:5n3 and 36:5n3 account for 0. 71% and 1.6%, respectively. From 20:4n6/DHA, 34:4n6 and 36:4n6 were only 0. 46% and 0. 61%, respectively. The total relative mol% of n3 VLC-PUFAs synthesized from EPA was almost two times that of n6 VLC-PUFAs synthesized from AA.
CONCLUSION: ELOVL4 protein preferentially elongates n3 PUFA to VLC - PUFAs over n6 PUFA. Dietary supplementation of appropriate n3/n6 PUFAs may provide STGD3 patients with some therapeutic benefits.

Objective To analyze the molecular characteristics of Salmonella paratyphi A ( S. pa-ratyphi A) strains prevailing in Hangzhou area in recent years. Methods Pulse field gel electrophoresis ( PFGE) and multiple-locus variable-number tandem repeat analysis ( MLVA) were performed for molecular typing and epidemiological analysis of 72 S. paratyphi A strains isolated in Hangzhou area during 2002 to 2013. Results The 72 S. paratyphi A strains were divided into 11 PFGE ( by using restriction enzymes of Xba Ⅰ and Bln Ⅰ) and 6 MLVA types. Among the selected 34 variable number tandem repeat ( VNTR) sites, 4 sites (1188K, 2075K, 2201K and 4346K) showed high polymorphism, in which PFGE displayed a higher resolution than MLVA. Except for the 5 PFGE types of X4B5, X7B7, X8B8, X9B9 and X10B10, the other 6 PFGE types belonged to a same clone sharing a similarity of greater than 95%, and the S. Paratyphi A strains in that clone accounted for 93. 1% of the total strains isolated in Hangzhou. Conclu-sion The occurrence of paratyphoid A in Hangzhou area from 2002 to 2013 was mainly caused by S. para-typhi A strains belonging to the same clone. Combination of PFGE with MLVA was conducive to epidemiolog-ical investigation of paratyphoid A.

ObjectiveTo evaluation application of MSCTA technology in pre-and pro-liver transplantation.MethodsThirty - two patients with liver transplantation were performed with multi-phase CT scanning (MSCT).In hepatic artery and portal phase vascular 3D imaging reconstruction methods include multiple planar reconstruction ( MPR),maximum intensity projection ( MIP),volume rendering (VR).MIP images were measured with these parameters (CA,LGA,CHA,PHA,PV,SV,SMV in diameter).ResultsHepatic arterial vascular imaging scan can show clearly within the scope of the abdominal aorta,gastroduodenal artery,hepatic artery,the left hepatic,celiac trunk,and its branches.Portal vascular imaging clearly showed that the portal vein system.MIP can use accurate measurement of vascular diameter abdominal aorta and portal,superior mesenteric vein,and splenic vein diameter.Control group with liver cirrhosis and liver cancer artery diameter had no significant difference in patients with portal hypertension and the portal vein [ ( 16.7 ± 2.4 ) mm ],mesenteric vein [ ( 10.8 ± 2.1 ) mm ],and splenic vein diameter [(13.1±1.9)mm] compared to the control group[(13.8 ±1.6)mm,(8.2 ±1.7)mm,(8.9±1.1)mm ],the difference was statistically significant ( P ＜ 0.05 ). Conclusions MSCTA can show the liver artery and portal vein system of the non-invasive method of checking,Joint MIP and VR application can provide more clinical liver transplant before the hepatic artery and portal vein of information,liver transplantation arteriovenous anastomoses provides for the monitoring of vascular diameter.

To report the clinical, radiological and neuropathological findings of a patient with rheuma-toid meningitis. The patient was a 71-year-old Chinese man with a two-year history of rheumatoid arthritisand no other significant medical history, who presented to our hospital recurrent weakness of his left ex-tremities, dysarthria and a continuous bilateral hand tremor. Cerebrospinal fluid (CSF) and serumexam-inations were normal apart from a mildly raised serum perinuclear antineutrophil cytoplasmic autoantibody(p-ANCA). Brain magnetic resonance imaging (MRI) showed leptomeningeal enhancementin both fron-tal and parietal lobes, in addition to several old white matter infarcts. Meningeal biopsy showed numerousinfiltrating macrophages and lymphocytes within the leptomeninges. The patient responded clinically andradiologically to corticosteroid and cyclophosphamide therapy. The patient subsequently developed herpeszoster over his left chest as a complication of his immunosuppressive treatment. His cyclophosphamidewas ceased and intravenous immunoglobulin (IVIG) therapy was commenced, with good clinical responseto both the herpes zoster and meningitis. According to the result of the biopsy, aseptic meningitis wasconsidered the MRI results and the patient’s clinical history were given, and a diagnosis of rheumatoidmeningitis was made. The patientwas p-ANCApositive. Although there was no evidence for cerebral vas-culitis on biopsy, it remains a possibility that the patient’s recurrent minor cerebral infarcts visible onMRI were vasculitic in nature.

? AIM: To investigate the differences between synoptophore and triple prism strabismometry and its possible cause.?METHODS: There were 347 patients with horizontal concomitant strabismus involved, in which 76 patients were esotropia, 37 patients were male while 39 were female, with average age of 13. 27 ± 7. 77 years old. There were 271 patients with exotropia, 131 cases were male while 140 were female, with average age of 15. 43 ± 8. 42 years old. All the patients were examined by synoptophore and prism plus shaded strabismometry in a long distance of 6m. Datas were analyzed by SPSS 17. 0.?RESULTS:In the exotropia patients, the conversions of circular degree(°) and prism degree(△) were:1°=0. 29△ ~1. 78△, which was statistically significant with intermittent strabismus (P=0. 001). While in the esotropia patients, the conversions were:1°=2. 01△ ~2. 15△.?CONCLUSION: The diversity between the two methods is enlarged with the increase of squint angle for exotropia patients. While in esotropia patients, the diversity decreased with the increase of squint angle. Synoptophore equipped with +7. 00D, defects of the triple prism itself and proximal convergence during exam may be the reasons for the diversity.

OBJECTIVETo analyze the clinical characteristics of elderly patients with spinal tuberculosis and explore its clinical effects with anti-TB drugs alone.

METHODSFrom January 2008 to July 2010, the data of 36 patients with spinal tuberculosis underwent conservative treatment of anti-TB drugs alone were analyzed. There were 19 males and 17 females with an average age of 73.5 years (ranged, 60 to 85). All patients were in the active phase with high ESR and CRP levels and were treated with 3HRZE/6-9HRE (course from 9 to 12 months). According to clinical symptoms, chemical examination, radiological image to adjust drug and depending on VAS score to evaluate pain.

RESULTSAll the patients were followed up from 8 to 24 months with an average of 15 months. Tuberculose of 31 patients healed after chemotherapy from 9 to 12 months and ESR and CRP recovered normally. Levofloxacin and para-amino salicylic acid were used in 4 cases because of 4 cases occurred drug fast for RFP or INH, after 15 months, their obtained healing. Symptom of 1 case got worse during chemotherapy, and surgical treatment were performed, after 3 months, ESR and CRP recovered normally, X-ray and CT showed spinal osteosclerosis and fusion without significant kyphosis and internal fixation loosening. Cobb angle was respectively(17.6+/-2.3) degrees, (18.1+/-2.7) degrees before treatment and last follow-up (P>0.05). MRI showed abscess was absorbed and spinal inflammation subsidised. VAS score was respectively 6.5+/-1.7, 1.4+/-0.5 before treatment and last follow-up (P<0.05). Seven patients had complications relating with drug adverse reaction,after discontinuation and treated with clinical symptom,the patients recovered normally.

CONCLUSIONAnti-TB drugs alone can obtain satisfactory effects in treating early senile spinal tuberculosis, but strict supervision and individual administration should not be disregardful.
