Objective To investigate the effects of monocyte CD141 and platelet CD36 on peripheral vascular endothelial function (VEF) in patients with hypothyroidism (PWH). Methods The number of mono-cyte CD141and platelet CD36 from 52 patients wtih PWH and 40 healthy persons (control group) was calculated by flow cytometry. VEF was detected in terms of brachial artery flow-mediated dilatation (FMD) using Doppler ultrasonography. The differences of expressions of monocyte CD141 and platelet CD36 were compared between the two groups, so was FMD. The association of monocyte CD141 and platelet CD36 with FMD (%) was analyzed by Pearson analysis. Results Expression of monocyte CD141 (%) was significantly higher in the PWH group than in the control group (21.79 ± 9.45 vs. 18.84 ± 9.64, P < 0.001), so was expression of platelet CD36 (%) (34.26 ± 10.23 vs. 28.65 ± 9.53, P < 0.001). FMD% was lower in the PWH group than in the control group (8.65 ± 1.97 vs. 11.25 ± 2.72, P < 0.001). CD141 was negatively correlated with FMD% (r = -0.657, P < 0.01), so was CD36 (r = -0.557, P < 0.01). Conclusions Both monocyte CD141 and platelet CD36 are significantly higher in the PWH group than in the control group. CD141 and platelet CD36 are negatively related with VEF.

Objective To classify the taxonomic status of O.cheni in relation to O.turkestanicum var. tuberculata from the mainland of China by comparing their nucleotide sequences of nuclear ribosomal partial large subunit gene (LSU). Methods The genomic DNA of adult worms were extracted by the GNT-K method. The target gene was amplified by PCR using specific primers. The PCR products were purified before ligation into the plasmid PCR-blunt (Invitrogen). Recombinant plasmids were amplified in E.coli , extracted and purified using routine methods and then sequenced using M13 primers (F/R) on a Licor long-read auto-sequencer. Sequences of O. turkestanicum was retrieved from GenBank and aligned with our data in BioEdit. Results The nucleotide sequences of LSU between O.turkestanicum var. tuberculata and O.cheni was 100% identical, and 99.99% identical between O.turkestanicum var. tuberculata and O.turkestanicum . Conclusion This study demonstrated high similarity in LSU nucleotide sequences, and the results do not support O.cheni as an independent species. O.cheni may be a synonym of O.turkestanicum var. tuberculata , and O.turkestanicum var. tuberculata is probably also a synonym of O.turkestanicum .

Methods Clinical data included conventional ultrasound and CEUS image of 133 cases (156 eyes) with orbital lesions were analyzed retrospectively . All lesions were confirmed by surgical pathology or clinical cure ,which included 26 cases of cystic lesions (epidermoid cysts ,dermoid cysts ,sebaceous cysts and mucous cysts) ,29 cases (30 eyes) of orbital hemangioma ,13 cases ( 16 eyes ) of inflammatory pseudotumor ,11 cases of lacrimal gland pleomorphic adenoma ,3 cases (5 eyes) of lymphoepithelial lesion ,36 cases (53 eyes) of malignant lymphoma ,5 cases of meibomian gland carcinoma ,4 cases of lacrimal gland adenoid cystic carcinoma ,3 cases of malignant melanoma and 3 cases of basal cell carcinoma . Results CEUS of benign cystic lesions showed the tumors were enhanced inhomogenously . Most CEUS of benign tumours displayed?slow in and slow out ,and high enhancement when reached the peak but the size of images had no change . While CEUS of malignant tumours showed?fast in and fast out ,homogeneous or inhomogeneous high enhancement and ill‐defined or irregular shape ,and volume increased compared to two‐dimensional ultrasound when reached the peak .Some other former district orbital lesions ,such as cystic lesion ,cavernous hemangioma ,pleomorphic adenoma and malignant lymphoma ,had their own ultrasound features . Conclusions CEUS combines with conventional ultrasound may contribute to the qualitative diagnosis of tumors in front of the orbit equator .

Objective To observe the expression of survivin and Aurora B in human pancreatic cancer BXPC3 cells after the treatment of sulindac and to explore the potential mechanism. Methods MTr assay was used to determine the effect of sulindac on the proliferation of the BXPC3 cells. RT-PCR was used to detect the expression of mRNA level of survivin and Aurora B, western blot was used to detect protein expression of survivin and Aurora B Thr-232. Cell cycle and apoptosis were detected by flow eytometry (FCM). Results The BXPC3 cells were inhibited by sulindac in a dose and time-dependent manner; the expression of mRNA of survivin and Aurora B were both significantly decreased from 1.5644 and 0.6554 to 0. 4372 and 0.1132 (P< 0.01), the expression of survivin protein and the phosphorylation of Aurora B Thr-232 were also decreased from 1.2735 and 0.4680 to 0.2126 and 0.2546 (P<0.01); the proportion of cells in the G0/G1 phase was increased from (56.65±1.93)% to (70.58±3.21)% (P<0.01). Conclusions Sulindac had inhibitory effects on the growth of BXPC3 cells, the possible mechanism was via decreasing the expression of survivin which depressed the activity of Aurora B, then the CPC was influenced. The most of the cells were blocked in the G0/G1 phase, and the cells' mitosis was inhibited.

Naturally occurring mutations in surface proteins of Hepatitis B virus(HBV)usually result in altered hepatitis B surface antigen(HBsAg)secretion efficiency.In the present study,we reported two conserved residues,M75 and M103 with respect to HBsAg,mutations of which not only attenuated HBsAg secretion(M75 only),but also suppressed HBV genome replication without compromising the overlapping p-gene product.We also found M75 and M103 can initiate truncated surface protein(TSPs)synthesis upon over-expression of full-length surface proteins,which may possibly contribute to HBV genome replication.However,attempts to rescue replicationdefective HBV mutant by co-expression of TSPs initiated from M75 or M103 were unsuccessful,which indicated surface proteins rather than the putative TSPs were involved in regulation of HBV genome replication.

ObjectiveTo investigate the effectiveness and safety of insulin glargine in the treatment of patients with type 2 diabetes mellitus (T2DM),and verify the new remedy called one central and three steps for T2DM.MethodsUsed multicenter,random,open and self-control study.Two hundred and three cases with T2DM treated with insulin glargine were divided into four groups according to different therapy:30 cases with one needle method,106 cases with one needle and one pill method,48 cases with one long-acting and several short-acting method,and 19 cases with one long-acting,one pill and several short-acting method.The changes of blood glucose,glycosylated hemoglobin (HbA1c),weight and so on before and after treatment were observed.ResultsThe levels of fasting plasma glucose(FPG),2 h postprandial plasma glucose (2hPPG) and HbA1c decreased significantly after treatment than those before treatment[(5.78 ±0.76)mmol/L,(8.37 ±:1.37) mmol/L,(6.81 ±0.38)％ vs. (11.73 ±4.49) mmol/L,(16.73 ±4.96) mmol/L,(9.43 ± 2.31 )％,P ＜ 0.01 ].The weight and body mass index had no obvious changes before and after treatment( P ＞ 0.05 ).There was significant difference in the level of FPG,2hPPG and HbA1c before and after treatment in four groups respectively(P＜0.01 ).There was only 1 case who occurred hypoglycemia during the treatment.ConclusionThe therapy,one central and three steps,is not only effective and safe,but also convenient and cheap for T2DM.

Objective To discuss the impact of relevant psycho-social factors on the driving adaptability. Methods A total of 870 vehicle drivers were screened out by stratified cluster sampling,and 620 drivers were finally selected for this study after eliminating those who had 1 -2 accidents. The 620 drivers were divided into accident group and non-accident group. Demographic questionnaire, life event scale, SCL-90 Scale and Eysenck Personality Questionnaire were applied to investigate their general condition, life event, mental health and personality. All data were analyzed by t test and stepwise Fisher discriminatory, and then the discriminatory equations of driving eligibility were established. Results The scores of factors including positive life events, negative life events, family events, work events and social events in accident group were 9.62 ± 11.36, 34.53 ± 30.01, 24.05 ± 23.09, 16.78 ± 17. 12 and 2.82 ± 5.07, respectively, which were higher than 4.67 ± 6.25, 6.38 ± 10. 15, 6.48 ± 9.43, 3.96 ±6.55 and 2.02 ± 5.43 respectively in the non-accident group ( P ＜ 0. 01 ). The total SCL-90 score and the scores of all factors in the accident group were higher than those in the non-accident group ( P ＜0. 01 ). The Eysenck Personality Questionnaire scores of the accident group were significantly higher than the non-accident group in N dimension ( 56. 32 ± 8.77 vs. 45.23 ± 8.06 ) and P dimension (52.22 ±10.43 vs. 48.31 ± 9.35 ) ( P ＜ 0. 01 ). Fisher discriminatory equations: Faccident group = 0. 258 × X6 + 0.119 ×X9 +0.637 ×X17 +0.043 × X5-7.476; Fnon-accident group =0. 137 × X6-1. 000 ×X9 + 1.423 ×X17 +0.003× X5-2.601. Total discrimination accuracy of verification was 88.3%, and the total accuracy of prospective discrimination was 88.0%. Conclusions There is clear correlation of driving adaptability with coercion, anxiety, emotion and negative factors. The discriminatory equations are useful for selecting drivers because of high accuracy, and may play an important role in reducing the occurrence of traffic accidents.
