AIM: To compared therapeutic effect of compound trabeculectomy in treatment of angle - closure and open angle glaucoma.
METHODS: A total of 136 patients ( 136 eyes) with glaucoma from July 2014 to July 2015 were divided into angle-closure glaucoma (ACG) group with 72 cases (72 eyes) and open angle glaucoma ( OAG) group with 64 cases (64 eyes). All the patients were given compound trabeculectomy. The intraocular pressure, shallow anterior chamber, functional follicular and complications were compared between two groups after operation.
RESULTS: The intraocular pressure of all patients were significantly decreased at 1 and 3mo after surgery. The intraocular pressure of ACG group were significantly lower than that of OAG group ( t = 11. 037, 12. 660, P <0. 05). The intraocular pressure control rate of ACG group (98. 6%) was significantly higher than that of OAG group (89. 1%) (χ2 = 5. 580, P<0. 05) at 3mo after surgery. The shallow anterior chamber total incidence of ACG group was 11. 1%. It was significantly lower than OAG group (25. 0%) ( χ2 = 4. 497, P < 0. 05). The functional follicular formation rate of ACG group was 62. 5%. It was significantly higher than OAG group (43. 5%) (χ2 = 4. 035, P < 0. 05 ). There were no statistically significant on complications between two groups (5. 6% vs 7. 8%, P =0. 475).
CONCLUSION: Compound trabeculectomy can reduce intraocular pressure of ACG and OAG patients safely. The results in ACG patients is better than that in OAG patients.

Proteinase activation receptor-2 (PAR-2) is one of the G protein coupling receptor family members.It exists in all over the epithelial cell surface of gastrointestinal tract,and is easy to expose to the proteinase that can activate it.It is a direct exocrine regulator of many digestive glands,and directly affects the capability of gastrointestinal tract.At present,the PAR-2's unique activation way,its wide distribution in digestive system and its complicated physiological functions,especially the relation between PAR-2 and the gastrointestinal movement and perception,are being highly concerned.

ObjectiveTo observe the different mode of administration of lidocaine on hemodynamic effects during self-retaining laryngoscope.Methods75 adult patients,underwent selective operations of removal and biopsy of the vocal polype,epiglottis or laryngeal tumor via self-retaining laryngoscope under general anesthesia,were randomly divided into three groups,with 25 cases for each.Group Ⅰ was the control group; Group Ⅱ was the throat spraying group;Group Ⅲ was the intravenous drug group.The incidence of irritating cough and the changes of mean arterial pressure(MAP) and hear rate(HR) were observed during operations.ResultsThe incidence of irritating cough in group Ⅱ was lower than in group Ⅰ and group Ⅲ ( all P ＜ 0.05 ).MAP,HR in group Ⅱ was also lower than that in group Ⅰ and Ⅲ during extubation( all P ＜0.05).However there were no significant differences on MAP,HR between group Ⅰ and group Ⅲ during extubation( all P ＞ 0.05 ).ConclusionLidocaine spraying on larynx could alleviate irritating cough and had significant preventive effect on cardiovascular response,and the effect in this method was superior to intravenous injection.

AIM:To examine the efficacy and safety of cryotherapy in the management of Fusarium corneal ulcer.
METHODS: Retrospective contract analysis of the clinical data of 41 patients ( 41 eyes ) who infected with Fusarium corneal ulcer.

BACKGROUND: Differentiation of neural stem calls (NSCs) was mediated by many environmental factors. Several factors can induce NSCs to differentiate into neurons in varying degrees and it is now a focus on the control of NSCs differentiation.OBJECTIVE: To study the effects of combination of basic fibroblast growth factor (bFGF) and brain-derived neurotrophic growth factor (BDNF) on the differentiation of NSCs into neurons.DESIGN, TIME AND SETTING: The in vitro cytology observation was performed at the Neurotomia Laboratory of China Medical University in May 2008.MATERIALS: Three adult male SD rats were provided by Experimental Animal Center of China Medical University.METHODS: Dispositions to the rats were consistent with ethical standards of animals. The rat brain hippocampus was removed sterilely. After trypsin digestion, NSCs were cultured in serum-free medium. Cell suspension was prepared and diluted when the diameter of the fourth passage of clone sphere was 200 μm by mixture of DMEM/F12 containing 2% B27, 20 μg/L of epidermal growth factor (EGF), and 20 μg/L bFGF. Monoclonal calls were passagad. NSCs were divided into blank control, bFGF, BDNF and bFGF+BDNF groups by different growth factors added into the media. Fetal bovine serum of 0.1 volume fraction was added in blank control group. The media in the other three groups were added bFGF, BDNF and bFGF+BDNF respectively for 1 week.The concentration of bFGF was 10 μg/L and the concentration of BDNF was 200 μg/L.MAIN OUTCOME MEASURES: Immunocytochemistry staining was used to identify NSCs as well as to detect the differentiation of NSCs into neurons.RESULTS: The monoclonal calls expressed nestin and the differentiated call expressed neuron specific enolase and glial fibrillary acidic protein. Compared to blank control group, the proportion NSCs into neurons in the bFGF group, BDNF group and bFGF+BDNF group were much higher (t=3.409-7.558, P < 0.05), with the highest in bFGF+BDNF group (t =7.558, P < 0.05).CONCLUSION: Combination of bFGF and BDNF can promote the differentiation of adult hippocampus NSCs into neurons.
