1.Progress and prospect of treatment for ocular Beh(c)et disease
Chinese Journal of Experimental Ophthalmology 2016;34(8):761-764
Ocular Beh(c)et disease,which usually presents as panuveitis,with characteristic of vision impairment and relapse,is one of the most refractory uveitis entities.Usually,one or more conventional immunosuppressive agents,such as glucocorticoid,ciclosporin,chlorambucil,cyclophosphamide,etc,are needed in disease management.However,long-term use of immunosuppressive agents would result in severe adverse effects.New biologics,such as interferon,antitumor necrosis factor agents,interleukin or its receptor antagonists,provide new therapeutic approaches to the treatment for this disease.This paper reviewed the conventional therapies and biologics applied in ocular Beh(c)et disease.

Objective To analyze the expression stability of the three widely used reference genes β-glueuronidase (GUSB), glycera]dehydes-3-phosphate dehydrogenase (GAPDH), β2-microglobulin (β2-M) in Chinese lung cancer tissue specimens and normal lung tissue specimens. Methods Gene expression wasmeasured by quantitative real time PCR and expression stability was analyzed with two widely used softwares genorm and normfinder. Results The intra-and inter-group difference of GAPDH is maximum (The intra and inter-group s is 1.07 and 0.93 respectively, |△ Ct|=2.01±1.06; P =0.000). The mean of these three genes' Ct value is the most stable one analyzed by the two softwares. But the t test showed that the mean of Ct value of GUSB and β2-M is the unique combination that had the minimum intra-and inter-group difference, with no statistically significant differences between normal and malignant samples (The intra-and inter-group s is 0.53 and 0.79 respective]y, |△Ct|= 0.73±0.53; P =0.053). Conclusion It is inappropriate to normalize data derived from lung tissue specimens using one of these three housekeeping genes alone. Among the different combinations of these three genes, the mean of the Ct values of GUSB and β2-M is the best choice as the internal control of lung tissue specimens.

Aim To study the effect of saikogenin d (SGD) on prostaglandin E 2(PGE 2) production in C 6 rat glioma cells. Methods Radioimmunoassay was applied to determine PGE 2 production in the cells. Scintillation counting was used to measure liberation of -arachidonic acid (AA) from the cells labeled with -AA. Results In vitro, SGD alone at 1~20 ?mol?L -1 did not affect PGE 2 release from cells, but inhibited its release induced by A23187, a Ca 2+ ionophore. The inhibition was concentration-dependent, with the IC 50 value of about 3 ?mol?L -1. SGD (2~10 ?mol?L -1 ) had no inhibitory effect on A23187-induced AA release or on the conversion of AA to PGE 2 in microsomal preparations. Conclusion SGD inhibites A23187-induced PGE 2 production in C 6 rat glioma cells in vitro, without either inhibition of free AA liberation or a direct inhibition of cyclooxygenase (COX) activity.

In this study, the cardiac structure and function in 102 athletes with high voltage of left ventricle inECG were examined by echocardiogtaphy, apexcardiography, systolic time intervals, X-ray cardiac measure-ment and physical work capacity tests. The parameters obtained were compared with those of 110 athletes withnormal voltage of left ventricle. Results showed no significant difference between these two groups either in cardiac structure (LYID,PWT, IYST) or in catdiac function (STI's, SV, EF, Vcf, PWV). The results of this study may be ofpractical value to the work of medical supervision and physical training.

Objective The incidence of breast cancer in China obviously keeps rising in recent years. The optical tomo?graphy image ultrasonography system ( OPTIMUS) is gradually applied in clinic as a new imaging diagnostic technique, but few system?atic studies are reported on its application to the diagnosis of breast tumors. The aim of this study was to assess the value of OPTIMUS in differentiating benign and malignant breast masses by measuring the maximum hemoglobin concentration ( MHC) in the lesions using OPTIMUS with the help of the results of controlled pathological study. Methods This prospective study included 380 cases of breast tumor ( 210 benign and 170 malignant ) treated from April 2009 to April 2014. We measured the MHC using OPTIMUS, detected the expressions of VEGF and PECAM?1/CD31 by immunohistochemistry, calculated the optimal threshold valve of MHC in predicting breast malignancy with the ROC curve, and analyzed the correlation of the MHC value with benign and malignant lesions, lymph node metasta?sis, and the expressions of VEGF and PECAM?1/CD31. Results The mean MHC was significantly higher in the malignant than in the benign lesions ([215.33±69.31] vs [116.50±55.31] μmol/L, P<0.01). The area under the ROC curve (AUC) was 0.836 (95%CI 0.684-0.989). The optimal threshold valve in the diagnosis of malignant breast lesions was 135.00 μmol/L, with a sensitivity of 84.7% and a specificity of 89%. When the tumor was≤2 cm, the MHC was significantly higher in the patients with lymph node metas?tasis than in those without ([207.73±66.43] vs [184.36±62.13] μmol/L, P<0.05). However, the MHC was markedly lower in the benign masses with VEGF and PECAM?1/CD31 negative than in the malignant lesions with VEGF and PECAM?1/CD31 positive ([116.50±55.31] vs [205.73±72.46] μmol/L, P<0.05) and strongly positive ([244.21±63.56] μmol/L, P<0.05). Strongly posi?tive expressions of VEGF and PECAM?1/CD31 were positively correlated with MHC ( P<0.05) . Conclusion Measurement of MHC by OPTIMUS contributes to the differential diagnosis of benign and malignant breast lesions and has a potential value for preoperative assessment of the prognosis of breast cancer.
