We report a case of retinal detachment in morning glory syndrome(MGS). We think that identification of the retinal break, removal of the traction force by vitrectomy, the use of long-acting gas as endotamponade, all contributed to the successful treatment of the disease. The pathogenic mechanisms of the disease and the function of B-scan to the diagnosis are included.

Objective To evaluate the effects of leucocyte-depleting filtration on systemic inflammatory response in patients undergoing valve surgery. Methods Fifty-two patients underwent elective mitral valve or mitral and aortic valves replacement surgery in this study. Patients were randomly divided into two groups. Each group (n=26) was placed on the same cardiopulmonary bypass (CPB) circuit except for the arterial line filter. One group of patients (CG) used the TERUMO ordinary arterial line filter as a control, and the Pall LG-6 leucocyte-depleting arterial line filter and TERUMO ordinary arterial line filter were incorporated into the arterial line of extracorporeal circuit in a parallel way in the EG. The leukocyte-depleting filters were used from 5-10 minutes before aortic cross clamp release to the end of CPB. Intra- and postoperative variables consist of leucocyte counts, serum levels of cytokines and complement C_3, body temperature and the usage of antibiotics. Statistical analysis with indepent-samples t-tests, paired-samples t-test, correlate and chi-square (SPSS11.5) was performed on all data to test for significant differences. A P value of

Objective To investigate the expression of Fas/FasL in children with aplastic anemia(AA) and its clinical significance.To explore the pathogenesis of AA.Methods CD34+ cell counts and the expression of Fas/FasL in 12 children with severe AA(SAA),18 with chronic AA(CAA)and 10 normal children were detected by flow cytometry combining monocolon antibody.Results The expression of Fas in children with AA were significantly higher than that in control group(P0.05).Conclusions Fas/FasL systeam take part in inducing CD34+ cell apoptosis.This may contribute to understanding the decrease number of stem cells and bone marrow failure.

Objective To explore the expression of aquaporin (AQP)-4 in white matter of spinal cord after spinal cord contusion (SCC). Methods 88 adult Sprague-Dawley rats were assigned randomly to sham operation group and SCC group. The model was established by Al-len's method. BBB sore was used to assess the motor function of rats. The relative expression of AQP-4 mRNA was determined by Q-PCR technique. The localization of AQP-4 was observed by immunohistochemistry. Results BBB score showed motor dysfunction in SCC group, and it increased 7 and 14 days after SCC (t>5.061, P<0.001). The level of AQP-4 mRNA decreased on the 1st and 3rd days (t>50.44, P<0.001), and increased on the 5th day (t=-3.968, P=0.001), and lasted until the 28th day (t=-4.227, P=0.001) compared with that on the 3rd day. The immunohistochemistry showed AQP-4 was located on the process of glial cell and vascular endothelial cells in white matter of spi-nal cord. Conclusion AQP-4 may play various roles at different stages in SCC.

Objective To investigate the effects of zinc gluconate combined with Danshen injection on the plasma lipid level following exposure to noise in rats. Methods Fifty female SD rats were randomly divided into a control group, a noise exposure group (model group), a zinc gluconate + noise exposure group (zinc gluconate group), a Danshen injection+noise exposure group (Danshen injection group) and a zinc gluconate+Danshen injection+noise exposure group (combination group), 10 rats in each group. The zinc gluconate group received intragastric administration of zinc gluconate 8-10 mg/(kg?d), the Danshen injection group received intraperitoneal injection of Danshen injection 6 mg/(kg?d), the combination group received intragastric administration of zinc gluconate 8-10 mg/(kg?d) and intraperitoneal injection of Danshen injection 6 mg/(kg?d). On the day 10, except in the control group, the rats in the rest of the groups were continuously exposed to high frequency steady noise for 7 days (4 000 Hz, 95 dB, 3 h/d). The serum levels of total cholesterol (TC), triglycerides (TG), high density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) were detected. Results The serum levels of TC (1.88 ± 0.17 mmol/L vs. 1.55 ±0.09 mmol/L), TG (1.45 ± 0.38 mmol/L vs. 1.01 ± 0.27 mmol/L), LDL-C (0.29 ± 0.04 mmol/L vs. 0.23 ± 0.03 mmol/L) in the model group were significantly lower than those in the control group (P<0.01 or P<0.05), while the serum HDL-C level in the model group were significantly lower than that in the control group (0.55 ± 0.08 mmol/L vs. 0.62 ±0.06 mmol/L;P<0.01). The serum TC level in the zinc gluconate group was significantly lower than that in the model group (1.71 ± 0.11 mmol/L vs.1.88 ± 0.17 mmol/L;P<0.05). The serum levels of TC (1.73 ± 0.21 mmol/L vs. 1.88 ± 0.17 mmol/L) and LDL-C (0.25 ± 0.03 mmol/L vs. 0.29 ± 0.04 mmol/L) in the Danshen injection group were significantly lower than those in the model group(all P<0.05). The serum levels of TC (1.57 ± 0.21 mmol/L vs. 1.88 ± 0.17 mmol/L), TG (0.84 ±0.40 mmol/L vs. 1.45 ± 0.38 mmol/L) and LDL-C (0.24 ± 0.05 mmol/L vs. 0.29 ± 0.04 mmol/L) in the combination group were significantly lower than those in the model group (P<0.01 or P<0.05), and the serum HDL-C level (0.61 ± 0.07 mmol/L vs. 0.55 ± 0.08 mmol/L) in the combination group was significantly higher than that in the model group (P<0.05). Conclusions Noise exposure may induce dyslipidemias in rats. Zinc gluconate and Danshen injection can regulate the plasma lipid level following exposure to noise in rats, and combination of zinc gluconate and Danshen injection may be superior to zinc gluconate or Danshen injection alone.

AIM:To investigate the effect of calcitonin gene related peptide(CGRP)on the expression of cyclic AMP response element binding protein(CREB)and phosphorylated-CREB in rat parietal cortex during focal cerebral ischemia/reperfusion(I/R).METHODS:Focal cerebral ischemia/reperfusion model was induced by occlusion of the right middle cerebral artery using the intraluminal suture method.The expressions of CREB and phospho-CREB in the parietal cortex in different groups(sham group,focal cerebral ischemia/reperfusion group and CGRP group)were detected with immunohistochemistry and Western blotting,and the positive products were analyzed by image analysis system.RESULTS:There was definite expression of CREB in right parietal cortex in sham group,while it was lesser in I/R group than that in sham group,but it became more in CGRP group than that in I/R group(P
