Superficial siderosis of the central nervous system is a seldom disease in clinical practice. Its most common clinical manifestations are hearing loss and ataxia. It is a hemosiderin deposition in the surface of the brain and spinal cord after chronic subarachnoid hemorrhage. Magnetic resonance imaging can make the diagnosis. However, further research and clinical verification are needed.

0.05 ).However,there were more eccentric plaques in ruptured than in non-ruptured groups ( P

Objective To explore the value of intravascular ultrasound (IVUS) in diagnosing plaque disruption and arterial thrombosis.Methods Balloon-induced arterial wall injury and then feeding on a diet of 1% cholesterol for 8 weeks, 17 New Zealand white rabbits were established as atherosis(AS) models.At the end of the eighth week, the resulting plaques were incubated transluminally with recombinant adenovirus carrying a p53 transgene. After two weeks, the rabbits underwent pharmacological triggering with Russell viper venom(RVV) and histamine. IVUS was used before and after the rabbits were triggered pharmacologically. The value of IVUS in diagnosing plaque disruption and arterial thrombosis was derived by comparing the results of IVUS with pathologic findings. Results IVUS found that plaques disruption and thrombosis occurred in 12 of the 14 rabbits, totally 18 thrombi. A histologically confirmed plaque disruption and intraluminal thrombus were visualized in 12 of the 14 rabbits, totally 20 thrombi. By comparing the results of IVUS with histopathology, the true positive rate was 85% and false negative rate was 15%, the sensitivity and specificity of IVUS were respectively 85% and 67%. IVUS data correlated well with the histopathology regarding thrombus length(r=(0.73),P(0.05)). Conclusions IVUS can detect plaque disruption and arterial thrombosis.

Objective To investigate the effect of the mild conjunctivitis complication on the tear break-up time(BUT) in pa-tients with dry eye .Methods 93 patients with dry eye from Sep .2007 to Sep .2011 were selected .For all of them the BUT was 5 seconds or less than 5 seconds after corneal fluorescein staining .They were divided into experimental group (with mild conjunctivi-tis) and control group (without mild conjunctivitis) .We checked the BUT and compared the difference of BUT between experimen-tal group and control group .Results The average BUT of the 54 patients with complicated mild conjunctivitis ,of which conjuncti-val papillae was found in 40 cases ,was (3 .54 ± 1 .02)s ,the average BUT of the 39 patients without conjunctivitis was(3 .41 ± 1 .04) s .There was no significant difference between two groups .Conclusion Dry eyes complicated mild conjunctivitis had no effect on BU T .

Objective To compare the BIS values in patients under anesthesia with minimum alveolar concentration (MAC) of sevoflurane and median effective concentration (EC50) of propofol at loss of consciousness.Methods Sixty ASA Ⅰ or Ⅱ patients,aged 18-60 yr,undergoing elective surgery under general anesthesia,were equally and randomly divided into 2 groups:inhalational anesthesia with sevoflurane group (group Sev) and intravenous anesthesia with propofol ( group Pro).The end-tidal concentration of sevoflurane was monitored using Aestiva anesthesia machine (Datex Ohmeda) in group Sev.Anesthesia was induced with intravenous injection of etomidate 0.3 mg/kg,rocuronium 1 mg/kg,and remifentanil 0.2 μg/kg.The patients were mechanically ventilated after tracheal intubafion.Sevoflurane inhalation was started 12.5 min after intubation in group Sev.Propofol was given by target-controlled infusion with the target plasma concentration set at 3.8 μg/ml 12.5 min after intubation in group Pro.When the effect-site concentrations of propofol reached EC50 of propofol at loss of consciousness (2.2 μg/ml),1.3 EC50(2.86 μg/ml) and 1.5 EC50 (3.3μg/ml) and when the end-tidal concentrations of sevoflurane reached 1.0,1.3 and 1.5 MAC,BIS value,MAP and HR were recorded.Results HR was significantly higher at 1.3 MAC or 1.3 EC50,and at 1.5 MAC or 1.5 EC50 in group Pro than in group Sev ( P ＜0.05).BIS value was significantly decreased at 1.3 MAC or 1.3 EC50,and at 1.5 MAC or 1.5 EC50 compared with that at 1.0 MAC or EC50(P ＜0.05).There was no significant difference in MAP and BIS value at each time point between the two groups ( P ＞ 0.05).Conclusion No significant change in BIS values is found in patients under anesthesia with 1.0,1.3 and 1.5 MAC of sevoflurane and with 1.0,1.3 and 1.5 EC50 of propofol.

Objective To analyze the correlation of acute pancreatitis with hyperlipemia and C reactive pro-tein. Methods 42 patients with acute pancreatitis with hyperlipemia were divided into two groups of SAP group and MAP group under the diagnostic code. The blood fat and CRP were compared between the two groups, also the scores of APACHE Ⅱ , Ranson and CT were measured. Results The CRP and TG in group SAP compared with those in group MAP had significant difference(P<0.01),but the CHOL has no-difference;the scores of APACHEⅡ , Ranson and CT after control lipid in 42 patients were significantly' different( P < 0.05). Conclusion Hyperlipe-mia is one risk factors of the AP;combined with the CRP, it can be one evaluating index of the severity.

Objective To observe the effects of statins, angiotensin-converting enzyme inhibitor/adrenergic receptor binder ( ACEI/ARB ) treatment on Heme Oxidase-1 ( HO-1 ) expression in patients with coronary artery disease. Methods HO-1 expression in periphery white blood cells was detected using Western blot before and after 3 months treatment of the above antioxidants in 60 patients who were diagnosed as coronary artery disease by coronary angiography. Results HO-1 expression measured by gray scale peak by western blot was significantly higher after 3 months antioxidant treatment than that before antioxidant treatment( 168. 9 t6. 8vs 112.7 ± 6.3, P = 0.008 ). Conclusion Effects of statins and ACEI/ARB in treating coronary artery disease may be due to its promoting expression of HO-1.

Objective To investigate the influence of intraoperative posture intervention on drainage in patients after gynecological laparoscopic surgery. Methods A total of 1250 patients who were scheduled for gynecological laparoscopic surgery including laparoscopic-assisted salpingoplasty,oophorocystectomy,ectopic pregnancy,vaginal hysterectomy,myomectomy and appendectomy were randomly divided into two groups. The patients' posture was changed from Trendelenburg position to level lithotomic position during suction by the circulating nurses in the experimental group,while after surgery in the control group. The volume and time of drainage,and the length of stay after surgery were compared between the two groups. Results The volume and time of drainage,as well as the length of stay after surgery had significant differences between the two groups (P<0.05). Conclusions Intraoperative posture intervention is helpful for the treatment effect of drainage after gynecological laparoscopic surgery.
