1.Expression of Endothelial Nitric Oxide Synthase and Vascular Endothelial Growth Factor in Human Malignant Melanoma
Chinese Journal of Dermatology 2003;0(10):-
Objective To investigate the relationship between the expression of endothelial nitric oxide synthase (eNOS), vascular endothelial growth factor (VEGF) and the angiogenesis in human malignant melanoma (MM). Methods Tissue sections from 31 MM patients were examined. The protein expression of eNOS and VEGF was detected using immunohistochemistry technique and morphological quantitative analysis. Microvessel density (MVD) was also counted by immunostaining with anti-FⅧRAg antibody. Results (1)The positive staining of eNOS and VEGF was detected in 71.4% (24 cases) and 83.9% (26 cases) of MM respectively. As negative control there was no staining in the nevus pigmentosus tissue sections. (2)There was a positive correlation between the expression of eNOS and VEGF in MM. (3)The positive correlation was also found between the MVD and the expression of eNOS and VEGF in MM. The number of MVD was higher in MM than that in nevus pigmentosus tissue. (4)The lymphatic metastasis was not correlated with the expression of eNOS and VEGF. Conclusion The number of the MVD increases along with the high expression of eNOS and VEGF in MM.
2.Etiological factor and treatment of abnormal blinking in children
International Eye Science 2015;(4):639-642
Abnormal eye blinking in children is a disease of frequent eye blinking in children, more than 15 times per minute, without facial spasms and neurological diseases, with relatively independent clinical symptoms. If combining with organic or neurological disease, we consider it as children eye blinking syndrome. It's a common and frequently encountered disease in pediatric ophthalmology. The etiologies include body and psychological disorders, such as refractive errors, ocular surface and ocular adnexal disease, bad habits, lead pollution, tic disorders and so on. We think that most of abnormal eye blinking in children firstly caused by oculopathy, neurological disorders and psychological illness are the important factors for increasing or making it repeatedly happen. Recognizing and identifying the etiologies of abnormal eye blinking in children, so as to take a targeted theray and avoid misdiagnosis and delayed treatment.

Chinese Journal of Integrated Traditional and Western Medicine 2014;34(3):276-278
OBJECTIVETo observe the therapeutic effect of Yangxue Tongluo Recipe (YTR) combined with immunosuppressive agents in the treatment of rheumatoid arthritis (RA).
METHODSTotally 88 RA patients were randomly assigned to the treatment group [47 cases, YTR combined Methotrexate (MTX) + Leflunomide (LEF) treatment] and the control group (41 cases, MTX + LEF therapy). All patients received 12-week treatment. Clinical symptoms and signs, laboratory tests [erythrocyte sedimentation rate (ESR), rheumatoid factor (RF), and C reactive protein (CRP)], and adverse reactions were observed before and after treatment.
RESULTSThe total effective rate was 91.5% (43/47 cases) in the treatment group, and the total effective rate was 75.6% (31/41 cases) in the control group. There was statistical difference between the two groups (P < 0.05). The morning stiffness, the rest pain, the number of tender joints, the number of swollen joints, tender joint index, swollen joint index, ESR, RF, and CRP were significantly improved in the two groups after treatment (P < 0.01). Besides, clinical symptoms and signs, ESR, RF, and CRP were more improved in the treatment group after treatment, when compared with those in the control group (P < 0.05). Gastrointestinal discomfort was the main adverse reaction in the two groups, but the occurrence was lower in the treatment group than in the control group (P > 0.05).
CONCLUSIONSThe clinical efficacy of YTR combined MTX + LEF in the treatment of RA was better than using Western medicine alone. It was more safe with less adverse reactions.
