1.The effects of chemokines in ocular neovascular diseases
Chinese Journal of Experimental Ophthalmology 2013;(5):517-520
Chemokine is a family of small chemotactic cytokines.Chemokine mainly locates in neutrophile granulocyte,monocyte,macrophage,T lymphocyte and B lymphocyte,and some cells and immunoactive cells also secret cytokines.Researches showed that chemokine plays important roles in many patho-physiological activities,such as inflammatory response,infection procedure,wound healing,regulation of immunity,angiogenesis,invasion and metastases of cancer,etc..Some chemokine factors,such as hyperglycemia,hypoxia,oxidative stress,stimulate the ocular histiocytes to up-regulate the expressions of CXC chemokines and CC chemokines,which participate in the development of choroidal neovascularization and ocular neovascular diseases.This article reviews current progress in chemokine and the relationship between chemokines and ocular neovascular diseases,especially in diabetic retinopathy (DR) and age-related macular degeneration (AMD) etc..

ObjectiveTo evaluate the effect of low dose of dexamethasone on the blood glucose concentration in patients undergoing craniotomy. Methods20 consecutive patients undergoing craniotomy without a preexisting metabolic disorder were prospectively randomized into 1 of 2 groups: Dexamethasone (group D, n=10) and Normal Saline (group S, n=10), who were given dexamethasone 10 mg intravenous bolus or a saline placebo preoperatively. Arterial glucose concentrations were measured immediately before and after treatment and hourly for 5 hours intraoperatively. ResultsThe arterial glucose concentration in group D increased significantly(F=3.133,P<0.05), while those in group S keep stable. Compared with group S, arterial glucose concentration in group D increased significantly 180 min after dosing(P<0.01). ConclusionIf dexamethasone is used during craniotomy, perioperative blood glucose level should be carefully monitored and controled.

Objective To explore the effect classroom teaching quality evaluation on the improve-ment of teaching quality. Methods In-service teachers offering classes to undergraduates majoring in clinical medicine during the period of 2010 to 2011 in Tangshan Clinical Hospital of Hebei Medical University were enrolled as research objectives. Totally 128 teachers(majored in 16 disciplines), screened out from the enrolled teachers, met the criteria and passed through the evaluation in terms of class quality of lessons. They were arranged in descending order and the top 15%were grouped as the preeminent group while the 15%at the bottom were classified as standard group and the rest 70%as good group. Descriptive analysis was made to appraise results from four respects:major and discipline, records of formal school-ing, professional ranks and titles and length of teaching experience. Results Based on the analysis of teaching situation in major disciplines, the top 3 disciplines possessing the largest proportion of preemi-nent teachers were neurology ( 50%) , otolaryngology-head and neck surgery ( 40%) and surgery (20.6%). When it comes to the analysis of formal schooling records of teachers , there is no distinct dis-crepancy in rate of standard reaching between teachers with postgraduate degree and teachers with gradu-ate degree. However, rate of standard reaching was slightly higher in teachers with other degrees than teaching with undergraduate degree or above. In the analysis of professional ranks and titles, the proportion was 94.6%in teachers with senior professional title(associated senior professional title and senior profes-sional title) and the teachers with medium grade professional title only occupied a proportion of 5.4%. In the dimension of teaching years, rate of outstanding and good teachers was relatively high in teachers with 8 teaching years and teacher with less than 3 teaching years, whereas the outstanding rate was low and rate of standard reaching was high in teachers with the 3-4 teaching years. Conclusions Measures to enhance the quality of teaching can be found out according to the analysis of influencing factors of teaching quality evaluation.

Background Reasearches showed that α-melanocyte-stimulating hormone (α-MSH) inhibits inflammation and ameliorates the ocular surface abnormalities in a scopolamine-induced dry eye rat model,and the managing effect of sodium carboxymethylcellulose (CMC) on dry eyes also has been determined.However,whether α-MSH can enhance the therapeutic effects of CMC remains to be investigated.Objective This study was to investigate the protective effects of α-MSH combined with CMC on ocular surface in a scopolamine-induced dry eye rat model.Methods Sixty clean female Wistar rats were randomly divided into normal control group,model control group,NaCl group,CMC group,α-MSH group and α-MSH+CMC group,and 10 rats for each group.The dry eye models were established by subcutaneous injection of scopolamine hydrobromide at 9:00,12:00,15:00 and 18:00 per day for 28 days.0.9% NaCl solution,1×10 3 mg/ml α-MSH solution,0.5% CMC eye drop,and 1 ×10-3 mg/ml α-MSH+0.5% CMC solution were topically administered twice a day (8:00,17:00) since the initial day of modeling according to grouping.Shirmer Ⅰ test (S Ⅰ t),breakup time of tear film (BUT) and corneal fluorescence staining were performed before and 7,14,21,28 days after the application of drugs.At 28 days following the administration of drugs,the eyeballs of the rats were collected.Hemotoxylin and eosin staining was employed to examine the morphology of corneas,and periodic acid schiff (PAS) staining was used to count the conjunctival goblet cells.This study protocol was approved by Experimental Animal Ethic Committee of Tianjin Medical University (SYXK 2009-0001),and the use and care of the rats complied with ARVO Statement.Results The S Ⅰ t and BUT values were significantly reduced,and the corneal fluorescence staining scores were significantly increased over time following modeling in the model control group (all at P<0.01).No significant differences were found in the S Ⅰ t,BUT and corneal fluorescence staining scores between model control group and NaCl group at various time points (all at P>0.05).At 7,14 and 21 days after intervention,the S Ⅰ t values were (4.800±0.789),(4.100±0.516) and (4.300±0.856) mm in the α-MSH+CMC group,which were considerably higher than (2.875 ±0.719),(2.375 ±0.619) and (2.532±0.957)mm in the NaCl group (all at P<0.01).At 7 days after intervention,the BUT values were (4.938± 1.843) seconds and (5.000±1.491) seconds in the α-MSH group and α-MSH+CMC group,which were significantly higher than (3.250±1.000) seconds in the NaCl group (both at P<0.01).The corneal fluorescence staining scores in the CMC group,α-MSH group and α-MSH+CMC group were significantly lower than that in the NaCl group,with the lowest score in the α-MSH +CMC group (all at P<0.05).The thickening of corneal epithelial layer,corneal edema and arrangement disorder of corneal stroma were found in the model control group and NaCl group;while slight corneal edema and epithelial cell proliferation were exhibited in the α-MSH+CMC group by hemotoxylin and eosin staining.PAS staining showed that the number of goblet cells was much more in the CMC group,α-MSH group and α-MSH+ CMC group than that in the model control group and NaCl group (all at P < 0.01).Conclusions The sole application of α-MSH or CMC alleviates ocular surface damage and morphological abnormality to certain extent,and the combination of α-MSH and CMC generates more effective protection in comparison with sole administration of α-MSH or CMC.The early application of the drugs plays an improvement role in tear secretion and tear film stability in dry eyes.
