Objective To investigate the association between the genetic polymorphisms of methylenetetrahydrofolate reductase (MTHFR) and ulcerative colitis (UC) of Han ethnic population in Zhejiang, China. Methods Two hundred and seventy-four consecutive patients with UC and 726 healthy controls (HC) were studied. The genetic polymorphisms of MTHFR (C677T and A1298C) were genotyped using PCR-RELP methods. Results The frequencies of variant allele and genotype in MTHFR A1298Cgene were higher in UC patients than in the HC (35.77% vs 29. 96%, P =0. 013; 52. 19% vs 44. 90%,P=0.039; respectively). However, there were no significant discrepancies of the allele and genotype frequencies in the MTHFR C677T gene between the UC patients and the HC (P ＞ 0. 05 ). In addition, the MTHFR 677Tr homozygote, T allele and 677CT/1298AC compound genotype were more prevalent in patients with extensive colitis than in those with distal colitis (37. 66% vs 14. 72% ,P = 0. 0002; 49. 35% vs 32.99% ,P =0. 0004; 29. 87% vs 15.23% ,P =0. 006; respectively). Furthermore,the variant allele in the MTHFR A1298C gene (C) in severe UC patients was significantly lower than in mild and moderate UC patients (18.97% vs 33. 88% ,P =0. 022). Conclusion The genetic polymorphisms of MTHFR C677T and A1298C are obviously associated with Han ethnic population with UC in Zhejiang province.

Objective To investigate clinical distribution and drug sensitivity of infectious pathogens in our wards for hematology malignancies. Methods Drug sensitivity tests of bacteria were performed by Kirby-Bauer method, 56 strains of pathogens were isolated from all detected samples. Results The results showed that the composition ratio of Gram-negtive bacteria, Gram-positive bacteria was 69.64%, 30.36%. In decreasing frequency, Escherichia coli (37.50%), Klebsiella pneumoniae (10.71%). All of staphylococcies were resistant to meticillin, and sensitive to vancomycin. Conclusion This study indicates that Gramnegative bacteria remain the predominant pathogens in microorganisms causing bloodstream infections for hematological malignancies at Huashan Hospital. The incidence of Escherichia coli is the highest. All of staphylococcies were resistant to meticillin.

To investigate the feasibility to produce crocetin in tobacco plants.The coding region of zeaxanthin cleavage dioxygenase (CSzCD) gene from Crocus sativus L. was inserted into the downstream of the cauliflower mosaic virus (CaMV) 35S promoter of a binary vector pBI121, and integrated into the genome of Nicotiana tabacum L. Twenty-one transgenic lines were identified by genomic southern blotting analysis. Western blotting and HPLC analysis of the leaf extracts of transgenic tobacco showed that crocetin was produced in CSzCD gene-transformed plants, while no crocetin was found in the untransformed tobacco.

Objective To investigate the risk factors and prognosis influential factors of acute kidney injury (AKI) after cardiac surgery.Methods The clinical data of patients who were hospitalized and underwent cardiac surgery from April 2009 to May 2011 were collected prospectively.Demographic characteristics,types of surgeries,preoperative renal function,pre-and intra-operative conditions and clinical outcomes,etc were recorded.Results A total of 4007 patients underwent cardiac surgery were recruited.The overall incidence of AKI was 31.2％ (1250/4007).The incidence of AKI requiring renal replacement treatment (AKI-RRT) was 2.6％ (104/4007).The overall hospital mortality was 1.9％ (77/4007),and was significantly higher in AKI group than in non-AKI group (5.4％ vs 0.3％,P ＜0.01).The hospital mortality of AKI-RRT group was 36.5％ (38/104).Grouped by type of surgery,cardiac transplantation had the highest AKI incidence (73.0％) and highest in-hospital mortality (18.9％),followed by coronary artery bypass grafting (CABG) combined with valve surgery (AKI incidence 57.8％,in-hospital mortality 6.1％) and aneurysm surgery (AKI incidence 52.0％,in-hospital mortality 5.5％).Multivariate logistic regression analysis showed that man,age,BMI,hypertension,chronic heart failure,pre-operative serum creatinine (SCr) ＞ 106.0 μmol/L,intra-operative cardiopulmonary bypass time,intra-operative hypotension and aneurysm surgery were the risk factors of AKI after cardiac surgery.Multivariate logistic regression analysis showed that pre-operative SCr ＞ 106.0 μmol/L and intra-operative hypotension were independent risk factors of renal recovery after cardiac surgery while recovery of urine output was the favorable factor.Conclusions Cardiac surgery usually induces high AKI incidence and poor prognosis,which closely associated with many risk factors in peri-operative stage.The incidence of AKI is related to a number of perioperative risk factors.Heart transplantation,aneurysm surgery,CABG combined valve surgery are high risk surgeries.

Four new triterpenoids, together with six known analogues, were isolated from an aqueous extract of the Ziziphus jujuba var. spinosa seeds, by multiple column chromatographic separation methods using stationary phases of macroporous adsorption resin, MCI resin, normal phase silica gel, Sephadex LH-20, and Toyopearl HW-40C as well as preparative thin-layer chromatography and reversed-phase HPLC. Their structures were determined by spectroscopic data analysis, the new structures were trivially named jujubaceanothoside A (1), 23-epijujuboside A (2), and jujubosides J and K (3 and 4), while the known analogues were identified as jujubosides A-C (5-7) and II (8), alphitolic acid (9), and betulinic acid (10). The structure of 1 was confirmed by single crystal X-ray diffraction.

Ten dimeric phthalide racemates (1-10) were isolated from an aqueous extract of the Angelica sinensis root head (Guitou) by separation techniques of column chromatography over macroporous adsorbent resin, MCI resin, silica gel, and Sephadex LH-20, together with preparative thin-layer chromatography and reversed phase HPLC. The racemates were further separated into (+)-/(-)-1-(+)-/(-)-10 with chiral HPLC. Their structures including absolute configurations were elucidated by comprehensive analysis of spectroscopic data, combined with electronic circular dichroism (ECD) and NMR calculations as well as single crystal X-ray diffractions. Compounds (+)-/(-)-1-(+)-/(-)-10 are either new structure or new natural product, named (+)-/(-)-angelidipthalidic acids A-H [(+)-/(-)-1-(+)-/(-)-8] and (+)-/(-)-angelidipthalidols A and B [(+)-/(-)-9 and (+)-/(-)-10], respectively. Meanwhile, dimeric phthalide mono- and bis-lactone derivatives with 3.3′a,8.6′- and 3.6′,8.3′a-coupling patterns as well as determination of their relative configurations are discussed.

OBJECTIVETo evaluate the clinical efficacy of a combined in-office cold light bleaching and night-guard vital bleaching (NGVB) system for treating tetracycline stained teeth (TST).

METHODS90 patients with light, medium and heavy TST were randomly and evenly divided into 3 groups. 30 patients with 472 TST from the treatment group were treated with in-office cold light bleaching and NGVB, 30 patients with 466 TST from the control group 1 were treated with in-office cold light bleaching and 30 patients with 469 TST from control group 2 were treated with NGVB. At the time of treatment completion, after half a year and after one year, Vitalescence esthetic restorative masters shade guide was used to record the change of color. Bleaching efficacy and course of treatment were calculated, and lightening stability were evaluated.

RESULTS1) Three groups had satisfied lightening efficacy for light TST with 100% bleaching efficacy. The overall efficacy of treatment group and control group 2 were superior to the in-office cold light bleaching system (P < 0.05). Though there was no significant lightening efficacy difference between the treatment group and control group 2 (P > 0.05), the periods of treatment of the treatment group for light, medium and heavy TST were shortened by 43%, 46% and 49%, respectively, compared to the control group 2. 2) All three groups' treatment efficacy for light, medium and heavy TST became weaker progressively (P < 0.05). 3) For the treatment efficacy between the time of treatment completion and after half a year and one year, there was significant statistical difference (P < 0.01) for the control group 1, while there was no significant difference for both the treatment group and the control group 2 (P > 0.05). Both treatment group and control group 2 had better performance in treatment stability than control group 1.

CONCLUSIONIn treating the light and medium tetracycline stained teeth, the combined in-office cold light bleaching and NGVB system can achieve a more satisfied whitening result in much shorter period, and significantly enhance the long term whitening stability.
