Uveitis is a kind of inflammatory disease affected in ocular posterior segment.Uveitis sustains a long duration and causes a significant damage of visual function.It often leads to serious complications,such as cystoid macular edema (CME),cataract,glaucoma,retinal detachment and choroidal neovascularization (CNV).In the pathological process of uveitis,inflammatory factors promote the release of vascular endothelial growth factor (VEGF) through a variety of pathways.It has been verified that VEGF level is elevated in vitreous in the patients with uveiticinduced CME.Intravitreal injection of anti-VEGF drugs,including ranibizumab and bevacizumab,can improve the visual acuity in most patients with noninfectious uveitic-induced CME and CNV.However,intravitreously repeated injections of anti-VEGF drugs may be required in some patients.Intraocular injection of anti-VEGF drugs is an optional and effective way for those with persist macular edema and not being suitable for the use of corticosteroid or immunosuppressive therapy.However,anti-VEGF drugs may affect the efficacy of corticosteroid.Therefore,more clinical and basic researches are still needed.The status and progresses in the use of anti-VEGF drugs for uveitisinduced CME and CNV were reviewed.

Objective: To investigate the effect of chloride concentration on the corrosion of Co-Cr alloy and pure Ti in a simulated oral environment. Methods: The electrochemical corrosion tests of pure Ti and Co-Cr alloy were carried out in neutral artiifcial saliva solutions with different NaCl concentrations (0.9%, 2.0%, and 3.0%). hTe morphologies of corroded surface for pure Ti and Co-Cr alloy were observed by scanning electron microscope (SEM). Results: hTe changes in the self-corrosion potentials (Ecorr) for pure Ti and Co-Cr alloy in three kinds of artificial saliva solutions was not obvious. However, the self-corrosion current densities (Icorr) of pure Ti were much lower than those of Co-Cr. TheIcorr of Co-Cr alloy increased in a concentration-dependent manner of NaCl, whereas the breakdown potential (Eb) of Co-Cr alloy decreased in a concentration-dependent manner. hTe potential ranged for the breakdown of oxide film (Ev) was shortened in a concentration-dependent manner of NaCl. There was no obviousdifference in theIcorr of pure Ti with different concentrations of NaCl. hTe breakdown potential was not seen according to the polarization curves. Conclusion: In a certain range, the increase of the concentration of Cl- leads to accelerate the corrosion behavior of Co-Cr alloy, but it does not affect pure Ti.

To explore the value of acoustic radiation force impulse (ARFI) technique in the differential diagnosis of benign and malignant hepatic neoplasms.Retrospective analysis of touch tissue quantification (VTQ) and general ultrasonic examination of interesting region were performed for hepatocellular carcinoma (HCC),hepatic hemangioma,focal nodular hyperplasia (FNH) and controls.Significant differences existed between HCC and hepatic hemangioma,hepatic FNH and controls (all P ＜0.01).No significant difference existed between primary and metastatic HCC (P ＞ 0.05).There was no significant difference between hepatic hemangioma,FNH and controls (all P ＞ 0.05).With a cut-off VTQ value of 1.95 m/s,the sensitivity and accuracy rate in the differentiation of benign and malignant hepatic neoplasms was 90％ and 83％ respectively.The sensitivity and accuracy rate in general ultrasound examination of hepatic neoplasms was 88％ and 70％ respectively.Significant differences existed in accuracy rate between two methods (P ＜ 0.01).It was confirmed that ARFI could reflect the stiffness of liver neoplasm noninvasively.Compared with general ultrasonography,ARFI is better at differentiating benign and malignant hepatic neoplasms.

Objective To understand the attitude and current situation of medical English stud y as well as its relevant factors among long schooling medical students so as to provide first hand information for constructing students-centered medical English teaching model. Methods A self-de-signed questionnaire including basic information of students, attitude and current situation of medical English students was given to 134 seven or eight year program clinical medical graduates from grade 2006 to grade 2008 in Tongji University. Questionnaires were collected timely and an-alyzed with SPSS 19.0 and results were described by percentage. Results Totally 132 copies of questionnaire were recovered with an recovering rate of 98.51%. 56.82%(75/132) students had interest in medical English study and 71.97%(95/132)students had a will to go abroad for learning exchange. Main pur-poses for students to learn medical English were ‘professional literature reading’(68.94%,91/132),‘SCI papers writing’(59.09%,78/132)and ‘international communication’(58.33%, 77/132). Main influencing factors of medical English study were ‘boring teaching methods ’ ( 45 . 45%, 60/132 ) ,‘difficult medical English’(41.67%,55/132) and ‘insufficient teaching time’(40.91%,54/132).Conclusions Medical students with long schooling have demand for medical English study;however, most of them have some difficulties in practical application. Measures should be taken from three as-pects including students, teachers and curriculum setting to improve students' medical English.

It is a brief review of our research on the role of metallothioneins (MTs) in the occurrence and development of hepatocellular carcinoma (Hcc) in more than a decade,and the mechanism of prevention and treatment for Hcc in the field of TCM.It was found that MTs were required for the malignant proliferation of Hcc cells and their expressions significantly increased under different levels of stress.MTs may exert their effects on promoting proliferation via increasing ribosomal protein gene or other gene expressions.The over-expressions of MTs directly altered the balance of ions in the cell nucleus,and interacted on the genes promoting malignant proliferation.Hepatotoxicity and hepatic damage caused by DEN were reduced and relieved to different extents by the representative formula or constitute,which under the common therapeutic principle,by which MTs expressions were down-regulated as well.In conclusion,both effects above are important in the liver protection,inhibition of hyperplasia and carcinogenesis.

This study was aimed to explore the mechanism of Xin-Feng capsule (XFC) on pulmonary function of Sjogren's syndrome (SS) rat model based on the TGF-β1-ERK1 signal pathway. A total of 50 SD rats were ran-domly divided into the normal control (NC) group, model control (MC) group, hydroxychloroquine sulfate (HCQ) group, radix paeoniae alba (total glucosides of paeony capsules, TGP) group, and the XFC treatment group, with 10 rats in each group. Except the NC group, the complete Freund's adjuvant (CFA) and the same rat sub-mandibular gland antigen induced method were applied to each rat after metatarsus injection on two feet and CFA after sufficient emulsification of 0.2 mL submandibular gland protein mixed antigen induced SS. The water drink-ing quantity, body weight change, pulmonary function, ERK1, TGF-β1 protein expression and serum cell factor (IL-17, IL-4) changes were detected in each group. The results showed that compared with the NC group, the body quality and serum IL-4 of MC rats were obviously decreased, and the water drinking quantity, submandibu-lar gland / lung index, submandibular gland pathological score, ERK1, TGF-β1 integral and IL-17 were increased (P < 0.01 or P < 0.05), and the pulmonary function parameter was decreased (P < 0.01 or P < 0.05). Compared with the MC group, the body quality, pulmonary function parameters FEF50 and MMF of the XFC group were in-creased, the IL-4 expression was increased, the water drinking quantity, submandibular gland / lung index, sub-mandibular gland pathological score, serum IL-17 expression, ERK1 and TGF-β1 integral were decreased (P <0.01 or P < 0.05). Compared with the HCQ group, the body quality and IL-17 were significantly decreased in the XFC group (P < 0.01), FEF25, FEF75 and MMF were increased (P < 0.01 or P < 0.05). Compared with the TGP group, the lung index and IL-17 were decreased in the XFC group (P < 0.01 or P < 0.05). It was conclud-ed that the lung function of SS rats was declined, which is closely related to the activation of TGF-β1-ERK1 sig-nal pathway. Traditional Chinese medicine of XFC is able to downregulate the TGF-β1 expression and to restrain epithelium-mesenchymal cell transformation, in order to inhibit ERK1 phosphorylation activation and proliferation, decrease immune inflammation, in order to improve SS and lung function.
