Bilingual teaching has become an important teaching method in the Higher Medical Education.The major of Optometry and Ophthalmology in Wenzhou Medical College is an organic integration of the modem western optometry and traditional ophthalmology,and also have the advantage of international education background.In the past twenty years,we have made positive practices and explorations in bilingual teaching.In this paper,we will take The Contact Lens Course ( National recconmentation course and National bilingual demonstration course ) for example to share the useful experiences and results,and to set an important model in spreading bilingual teaching for other clinical medicine disciplines.

To prepare monoclonal antibody of carbohydrate antigen 19-9(CA19-9).Methods: Based on the titer test results of mouse ascites and its IC 50 values ,the mouse that prepare for fusion was identified.Positive monoclonal cell strains were established by cell fusing and screening.Monoclonal antibody from ascites was produced by peritoneal injection monoclonal cell , and then purified by octoic acid-ammonium sulfate precipitation method.After determine the protein concentrations by UV-spectrophotometry ,the monoclonal antibody against CA 19-9 was labelled with horseradish peroxidase.Based on antibody pairing test , DAS-ELISA method was established .To compared with abroad kit , analyzing performance of this method.Results: Three strains of monoclonal antibody were obtained.And the optimal working concentrations of mAb (ZJY3-1G9) ,as coated antibody,McAb(ZJY2-7F10),as HRP-IgG,were assured.Limit of detection was 26.4 U/ml.Linear range was 30-300 U/ml.By detecting patients with serum 33 , confirmed the correlation coefficient of r=0.950 4 , compared with abroad kit that measure simultaneously.Conclusion:Monoclonal antibody prepared for CA 19-9 can be used to develop a kit.

Objective To investigate choroid thickness at horizontal meridian with optical coherence tomography (OCT) and compare the choroid thickness difference between first visit myopia children with those children who wear orthokeratology lens for more than 1 year.Methods This retrospective study enrolled 68 myopia children with low to moderate myopia (-1.00--6.00 D) who visited our hospital and took choroid images by OCT.The total subjects were divided into 2 groups.The subjects of 34 children in group 1 visited for myopia initially and wear spectacles.The other one group wear orthokeratology lens more than 1 year.Only the data of right eye were analyzed.Scans through the fovea at horizontal meridian were acquired with OCT.Choroid images were detected by custom software with 500 μm intervals up to 3.5 mm around fovea.Choroid thickness (CT) was calc~ated based on the average of the 7 zones.Statistical analysis was performed to evaluate choroid thickness at each zone.ANOVA was used to compare choroid thickness differences between various zones in each group.Paired t test was used to compare choroid thickness difference at the same zone between two groups.Results The mean age of OK lens group was (12.3 ± 1.8) years old,and the spectacles group was (11.8 ± 1.4) years old,there was no statistical difference.From temple to nasal choroid,the mean CT of the orthokeratology lens group were (296.7 ± 61.8) μm (T3),(290.7 ± 58.9) μm (T2),(285.7 ± 57.4) μm (T1),(278.5 ±57.7) μm (M),(262.2 ±57.9) μm (N1),(239.8 ±59.7) μm (N2),(214.7 ±59.0) μm (N3);And the mean CT of the spectacles group were (294.2 ± 45.4) μm (T3),(292.0±44.0) μm (T2),(283.6 ±45.5) μm (T1),(272.0 ±51.6) μm (M),(255.2 ± 56.3) μm (N1),(236.5 ±58.1)μm (N2),(212.8 ±57.7) μm (N3),respectively.The thicknesses were significantly thicker in temple zones than that in nasal zones in each group (all P ＜ 0.05),but the CT was not significantly different between the two groups in each zone (all P ＞ 0.05).Conclusion The choroid thickness has regional deference in myopia children,the thickest is in the temple and the thinnest in the nasal region.There is no significant difference between the children who initially corrected by spectacles and those who wear OK lens more than 1 year.

OBJECTIVE: To investigate the protective effect and potential mechanism of tubastatin A (TubA), a specific inhibitor of histone deacetylase 6 (HDAC6), on renal and intestinal injuries after cardiopulmonary resuscitation (CPR) in swine. METHODS: Twenty-five healthy male white swine were divided into Sham group (n = 6), CPR model group (n = 10) and TubA intervention group (n = 9) using a random number table. The porcine model of CPR was reproduced by 9-minute cardiac arrest induced by electrical stimulation via right ventricle followed by 6-minute CPR. The animals in the Sham group only underwent the regular operation including endotracheal intubation, catheterization, and anesthetic monitoring. At 5 minutes after successful resuscitation, a dose of 4.5 mg/kg of TubA was infused via the femoral vein within 1 hour in the TubA intervention group. The same volume of normal saline was infused in the Sham and CPR model groups. Venous samples were collected before modeling and 1, 2, 4, 24 hours after resuscitation, and the levels of serum creatinine (SCr), blood urea nitrogen (BUN), intestinal fatty acid binding protein (I-FABP) and diamine oxidase (DAO) in serum were determined by enzyme-linked immunoadsordent assay (ELISA). At 24 hours after resuscitation, the upper pole of left kidney and terminal ileum were harvested to detect cell apoptosis by TdT-mediated dUTP-biotin nick end labeling (TUNEL), and the expression levels of receptor-interacting protein 3 (RIP3) and mixed lineage kinase domain-like protein (MLKL) were detected by Western blotting. RESULTS: After resuscitation, renal dysfunction and intestinal mucous injury were observed in the CPR model and TubA intervention groups when compared with the Sham group, which was indicated by significantly increased levels of SCr, BUN, I-FABP and DAO in serum. However, the serum levels of SCr and DAO starting 1 hour after resuscitation, the serum levels of BUN starting 2 hours after resuscitation, and the serum levels of I-FABP starting 4 hours after resuscitation were significantly decreased in the TubA intervention group when compared with the CPR model group [1-hour SCr (μmol/L): 87±6 vs. 122±7, 1-hour DAO (kU/L): 8.1±1.2 vs. 10.3±0.8, 2-hour BUN (mmol/L): 12.3±1.2 vs. 14.7±1.3, 4-hour I-FABP (ng/L): 661±39 vs. 751±38, all P < 0.05]. The detection of tissue samples indicated that cell apoptosis and necroptosis in the kidney and intestine at 24 hours after resuscitation were significantly greater in the CPR model and TubA intervention groups when compared with the Sham group, which were indicated by significantly increased apoptotic index and markedly elevated expression levels of RIP3 and MLKL. Nevertheless, compared with the CPR model group, renal and intestinal apoptotic indexes at 24 hours after resuscitation in the TubA intervention group were significantly decreased [renal apoptosis index: (21.4±4.6)% vs. (55.2±9.5)%, intestinal apoptosis index: (21.3±4.5)% vs. (50.9±7.0)%, both P < 0.05], and the expression levels of RIP3 and MLKL were significantly reduced [renal tissue: RIP3 protein (RIP3/GAPDH) was 1.11±0.07 vs. 1.39±0.17, MLKL protein (MLKL/GAPDH) was 1.20±0.14 vs. 1.51±0.26; intestinal tissue: RIP3 protein (RIP3/GAPDH) was 1.24±0.18 vs. 1.69±0.28, MLKL protein (MLKL/GAPDH) was 1.38±0.15 vs. 1.80±0.26, all P < 0.05]. CONCLUSIONS TubA has the protective effect on alleviating post-resuscitation renal dysfunction and intestinal mucous injury, and its mechanism may be related to inhibition of cell apoptosis and necroptosis.
