Unplug risk: A, B, C meaningful difference among the three groups(F=751. 121;P=0. 003), Group A scored the highest score of a minimum group C, respectively(6. 5±0. 7 ) and ( 1. 5±0. 7 ); A, B, C three groups comparison of differences twenty - two have significance(t=19. 642; t=20. 153; t=18. 345; P<0. 05). Group A had 8 patients had lower eyelid eversion, 5 cases of inferior lacrimal point expansion, 13 cases of sneezing, itchy nose, runny nose syndrome. Group B had 20 cases of varying degrees of now sneezing, itchy nose, runny nose syndrome. Group C had no serious complications.
CONCLUSION: Similar to A, B, C three groups of treatment efficacy, patient lacrimal functional recovery is safe and effective, which the group C treatment, during treatment and less material and fewer postoperative complications in patients, it is worth promotion.

Objective:To investigate the regulation of acupuncture on γ-interferon (INF-γ) and tumor necrosis factor (TNF) of lung cancer-operative cases. Methods: to determine the INF-γ and TNF contents in the blood serum of lung cancer patients by double antibody sandwich immuno-enzymatic method (ELISA); to measure the INF-γ and TNF contents of 30 lung cancer patients in the acupuncture anesthesia group and 30 lung cancer patients in general anesthesia group before the operation and at the 8th days, the 12th day after the operation respectively and make comparison between the two groups. Results:The pre-operation INF-γ contents of the two groups showed no significant difference (P＞0.05); the post-operation INF-γ contents of the two groups showed significant difference at 8th day and 12th day after the operation (P＜0.05); the acupuncture anesthesia group was superior to the general anesthesia group; the self-comparison of the anesthesia group showed significant difference at the 12th day and 8th day after the operation (P＜0.05); the pre-operation TNF contents of the two groups showed no significant difference (P＞0.05) and the post-operation TNF contents of the two groups showed significant difference at the 8th day and 12th day after the operation (P＜0.05). Conclusion:Acupuncture can increase the serum INF-γ and TNF contents of lung cancer patients and therefore regulate the immunity of the patients.

Tetrabromobisphenol A(TBBPA)is supposed to have potential thyroid disrupting activities due to its similar structure to thyroid hormones.TBBPA has been proved to show thyroid disrupting effects in vivo and in vitro studies.TBBPA might disrupt thyroid hormone system through transthyretin- and thyroid receptor-mediated pathways.The ability of TBBPA inducing the production of reactive oxygen species might be the extension of its thyroid disrupting activities.The thyroid disrupting effects of TBBPA might be closely related to its oxidative stress,reproduction toxicity and neurotoxicity.More experiments are required for the effects of TBBPA on the aquatic and amphibian animals.

Objective To evaluate diagnostic value of diffusion tensor imaging(DTI)in ringlike- enhanced lesions.Methods Nine abscesses,12 glioblastomas,10 metastases confirmed clinically or pathologically underwent conventional MRI and DTI.Average diffusion coefficient(ADC)value,fractional anisotropy(FA)value and maps were calculated in the central portion and peripheral edema of the lesions. Results On DTI,the abscesses displayed as hyperintense signal with hypointense or isointense signal of edema;but glioblastomas and metastases all showed as hypointense signal with isointense or hypointense signal of edema.On ADC map,the abscesses showed as hypointense signal,the mean ADC value was (0.66?0.07)x10~(-3)mm~2/s,The mean ADC value were(2.50?0.11)x10~(-3)mm~2/s and(2.37?0.52)x10~(-3)mm~2/s for the glioblastomas and metastases,respectively,all demonstrated as hyperintense signal with slightly hyperintense signal of edema.The difference between abscess and necrotic tumors was statistically significant(F=108.80,P

Objective To improve the awareness of the CT and/or MRI appearances and clinical presentations of Kasabach-Merritt syndrome(KMS),6 cases were reported.Methods The CT and/or MRI and clinical characters of 6 cases of KMS were reviewed and analyzed.Results Thrombocytopenia,and consumption coagulopathy were presented in all 6 cases.The paravertebral mass of posterior mediastinum, right pericardial lesion,skin and soft tissue of left arm were shown as iso-,hypointensity on T1-weighted image,iso-,hyper-intensity on T_2-weighted image,and with heterogeneous enhancement after contrast administration in three cases.Splenomegaly was presented in one case,it showed homogenous hypoattenuation on unenhanced CT,and diffused heterogeneous enhancement after contrast administration. On MRI,spleen was shown as hypointensity on T_1-weighted image,hyperintensity on T_2-weighted image, and with heterogeneous enhancement after contrast administration.There were lesions in both bones and spleen in one case.Osteopenia and thinned cortex were shown on the metaphyses of upper and lower extremities.Spleen enlarged and showed multifocal hypoattenuation lesions,the peripheral region enhanced on the early phase,and some of the lesions filled on the delayed phase after the contrast administration.One case showed huge hypoattenuation lesion in the left lobe of liver with gradually filling of the mass after peripheral enhancement.Conclusion Thrombocytopenia and consumption coagulopathy suggest the entity of extensive hemangioma.Splenomegaly with diffuse or focal hypoattenation or hypointensity in MRI infers the diagnosis of hemangioma.

AlM:To observe the changes of binocular vision in V-pattern exotropia children before and after surgical correction, and the effect of training in reconstructing the binocular vision after surgical corrections.METHODS: Sixty V-pattern exotropia children were enrolled in this study and were divided into three groups according to their age:group A (4~6 years old), group B (7~9 years old), and group C (10~12 years old), 20 cases for each group. Patients received routine refraction and ophthalmic examinations. Distance and near deviation were measured by prism-covering method and synoptophore. The simultaneous perception and fusion were examined with a synoptophore, and the stereacuity was measured with stereograms ( Titmus) . The children who didn’t reconstruct binocular vision function 1wk after surgery received binocular vision training. The data were recorded before and 1 , 2, 4, and 8wk after surgery. RESULTS: Binocular vision significantly improved among the children after surgery in group A and B ( P<0. 05 ) . Significantly divergence showed between group C and the other groups 1wk after surgery ( P < 0. 05 ). Binocular vision of the three groups all significantly improved 8wk after surgery, with no significant differences (P>0. 05). CONCLUSlON: V - pattern exotropia children can benefit from early surgical correction and training after surgery in reconstruct binocular vision.
