OBJECTIVE:To study the effect of dexamethasone (Dex) on expression of aquaporin-1(AQP1) in cultured human trabecular meshwork(HTM) cells METHODS:Reverse transcription combined with polymerase chain reaction(RT-PCR) was used to detect the expression of AQP1 in cultured HTM cells and those treated by Dex RESULTS:The mRNA of AQP1 expressed in normal HTM cells was 1 643?0 354,while 1 577?0 405,1 117?0 443,0 458?0 301,0 267?0 243 in those treated with Dex for 3 days in concentrations of 10-8mol,5?10-8 mol,10-7 mol,5?10-7mol As the concentrations of Dex increased to≥5?10-8mol,the expression of AQP1 was inhibited(P

ObjectiveTo evaluate the efficacy of intravenous and intra-arterial thrombolysis with urokinase for acute cerebral infarction.Methods Fifty patients with acute cerebral infarction occurred within 6 hours were divided into two groups by random digits table method with 25 cases each:intravenous and intra-arterial thrombolysis group and intravenous thrombolysis group.The patients in intravenous and intra-arterial thrombolysis group were given 200 000 U urokinase by intravenous infusion for 30 minutes immediately after being hospitalized,and arterial thrombolysis was prepared at the same time.With cerebrovascular angiography,the thrombolytic therapy was carried out in the target vessel blocking points through micro-catheter.Urokinase dissolved in 0.9％ sodium chloride was infused at the rate of 10 000 U per minute,the total volume would not be more than 1 000 000 U.The patients in intravenous thrombolysis group were given 1 000 000 U urokinase in 100 ml 0.9％ sodium chloride by intravenous infusion within 60 minutes.The clinical efficacy after thrombolysis was assessed according to the National Institutes of Health stroke scale (NIHSS) score,the quality of life was judged by Barthel index (BI) score and the prognosis was evaluated by modified Rankin scale (mRS) score of 90 days after thrombolysis.ResultsThere was no significant difference between two groups before thrombolysis according to the NIHSS score (P ＞ 0.05).After thrombolysis,NIHSS scores in two groups showed a downward trend,but they were obviously lower in intravenous and intra-arterial thrombolysis group after 24 h,7 d and 14 d than those in intravenous thrombolysis group [(8.97±4.56) scores vs.(11.01±3.65) scores,(6.88±2.31) scores vs.(8.34±3.05) scores,( 4.06±3.02 ) scores vs.( 6.73±2.15 ) scores ] ( P ＜ 0.05 or ＜ 0.01 ).BI scores before thrombolysis between two groups had no significant difference(P ＞0.05),while BI score of 90 days after thrombolysis in intravenous and intra-arterial thrombolysis group [(79.55±19.64) scores] was higher than that in intravenous thrombolysis group [(69.31±21.35) scores](P=0.0162).The rate of mRS score 0-2 (good efficscy) in intravenous and intra-arterial thrombolysis group [72.0％(18/25) ] was obviously higher than that in intravenous thrombolysis group [ 52.0％ ( 13/25 ) ] (P =0.0198 ).ConclusionsIt is significantly effective to treat acute cerebral infarction by superselective intravenous and intra-arterial thrombolysis.Therefore,it is supposed to be an optimal option for treating acute cerebral infarction in the future.

Objective To analyze the epidemiological characteristics of patients with sea lice injury in coastal baths in Qinhuangdao City, and provide scientific evidence for the importance of prevention of sea lice injury and the early warning of sea lice outbreak. Methods The data of 2 659 patients with sea lice injury, including gender, age composition, severity of bruises and other epidemiological data reported by the coastal bathing stations in Qinhuangdao City from 2016 to 2018 (mainly from July to August) were retrospectively analyzed, and the correlation between the temperature at the surface of sea water and the number of patients with sea lice injury was also analyzed. Results Among the 7 bathing beaches along the coast of Qinhuangdao City, Dongshan Bathing Spot (1 101 cases) and Repulse Bay Bathing Beach (1 365 cases) had the largest numbers of bruises, while the Gold Coast Bath had the least (only 5 cases), and the differences in number of bruises in different baths were statistically significant in 2016, 2017, 2018 years (277, 1 890, 492 cases respectively, χ2= 490.611, P < 0.05). Among 2 659 patients, 1 124 were children (≤14 years old), 1 535 were adult, 1 570 male and 1 089 female patients. The severity type of patients' sea lice injury in each bath was mainly mild to moderate type; among the total injury cases, there were 2 589 cases with mild type injury accounting for 97.37%, 61 cases with moderate type (2.29%) and 9 cases with severe type (0.34%). A linear trend between sea surface temperature and the patients' number of bruises was seen, and there was a positive correlation between the sea surface temperature and the patients' number (r = 0.433, P < 0.05). Conclusion The sea lice injuries in Qinhuangdao City are mainly distributed in the Dongshan and Repulse Bay Baths, the main type of injury is light one, and in the mean time the injury is influenced by factors such as popularization of science, medical care, environmental factors, and collective sea lice drift, etc.

To discuss the clinical characteristics and the imaging characteristics of hemichorea associated with non-ketotic hyperglycemia. Methods Six cases of hospitalized patients in our hospital with Non-ketotic Hyperglycemia Hemichorea were collected，summary analysis the clinical characteristics，the imaging characteristics. Results All the Six patients were acute onset，previous diabetes or hyperglycemia was found，the symptoms were as follows Hemichorea. Patients all showed platy or striatal heperdensity in the contralateral basal ganglia on head CT，and show ganglia hyperintensity on T-1-weighted MR imaging，hypointensity on T-2WI，the boundary was clear，the lesions often disappeared after treatment. Conclusion Hemichorea associated with non-ketotic hyperglycemia is mainly related to hyperglycemia and has characteristic CT and MRI features.
