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 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.

Objective To explore the clinical significance of expression of MKK4 in osteosarcoma,and to discuss the relationship between MKK4 and osteosarcoma occurrence,development and prognosis.Methods The expression of MKK4 protein was determined with immunohistochemical SP method in 30 cases of osteosarcoma.Results The MKK4 was obviously expressed in both nucleus and cytoplasm in osteosarcoma.The expression of MKK4 in the cytoplasm of osteosarcoma was positively correlated with clinical stage (r =0.72,P =0.000),the expression of MKK4 in the nucleus of osteosarcoma had no correlation with clinical stage (r =0.44,P =0.080).MKK4 expression in the cytoplasm was higher in transfer osteosarcoma than no transfer osteosarcoma(x2 =9.69,P ＜0.01),while no obvious difference in the nucleus of osteosarcoma(x2 =1.00,P =1.000).Conclusion The MKK4 is highly expressed in the nucleus and cytoplasm of osteosarcoma,suggests that MKK4 may be related with the carcinogenesis development of osteosarcoma.The expression of MKK4 in the cytoplasm of osteosarcoma is related to the malignant,metastasis and prognosis of osteosarcoma,may be used as a potential prognostic indicator of judgment osteosarcoma.

Objective To report on an autosomal recessive pyramidal tract, corpus callosum and peripheral nerve degeneration in a family and to study its relationship with other complicated hereditary spastic paraparesis. Methods Neurological examination revealed the following findings. Proband was a 20 year old man who spoke slowly and developed mental retardation in his childhood. Gait disturbance with pyramidal signs and mild cerebellar ataxia were found when the patient was 16. Slight sensory disturbance was present in the lower extremities. His 23 year old sister had similar symptoms at beginning of disease when she was 17. Their clinical courses were bad progressively. Electromyogram showed nerve conduction velocity decrease in the nerve medianus and neurogenic process in the muscle tibialis anterior. Cranial MRI, muscle and nerve suralis biopsies were examined in proband patients. Results MRI showed thin corpus callosum with cerebral and cerebellar atrophy as well as enlargement of ventricle system. Myopathological findings were characterized by angular atrophy fibers in small groups with appearance of hypertrophy fibers. The nerve suralis biopsy showed degeneration and regeneration of myelinated axons. Conclusion Our study confirms that this family is hereditary spastic paraparesis with mental retardation, thin corpus callosum and polyneuropathy reported mostly in Japan. Axonal polyneuropathy is a common pathological feature of this disease.
