Objective To explore the value of conventional and contrast‐enhanced ultrasound(CEUS) in the diagnosis of tumors in front of the orbit equator . 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 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 .

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.

Objective To observe the effect of sling exercise therapy (SET) on rehabilitation after knee arthroplasty. Methods 46 patients after knee arthroplasty were randomly divided into experimental group (n=23) and control group (n=23). The control group received continuous passive motion (CPM) training, while the experimental group received SET. They were evaluated with range of motion (ROM) of the knee, Hospital for Special Surgery Knee Score (HSS) and posture control ability before, 15 days and 3 months after operation. Results 15 days after operation, the maximal passive knee flexion was 6.0° more in the SET group than in the CMP group (95%CI=0.9°~11.2°; P<0.01), and the maximal active knee flexion was 5.7° more in the SET group than in the CMP group (95%CI=0.4°~9.1°; P<0.01); however, there was no significant difference in the maximal active knee extension, the maximal passive knee extension, HSS and posture control ability between 2 groups (P>0.05). 3 months after operation, there was no significant difference in all the items between 2 groups (P>0.05). Conclusion Compared with CPM, SET might be more effective on increasing knee ROM in the short-term, and could be used as an effective intervention for patients after knee arthroplasty at the early stage.

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.

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.
