OBJECTIVE: To comprehensively analyze the relationship between interleukin-6 (IL-6) and ischemic cerebrovascular disease. DATA SOURCES: A computer-based search was conducted in Pubmed for literatures related to the expression, effect, and significance of IL-6 in ischemic cerebrovascular disease pblished between January 1994 and March 2006 with the of "interleukin-6, Ischemia Cerebrovascular Disease; Interleukin-6, Ichemia Stroke", and the language was limited to English. STUDY SELECTION: Retrieved data were arranged, and articles with strong aim were selected. Literatures published recently and those published in authorized journals of the same region were superior. DATA EXTRACTION: A total of 122 relevant articles were retrieved, and 23 of them were in accordance with the inclusion criteria. DATA SYNTHESIS: IL-6 is a pleiotropic cytokine with both pro-inflammatory and anti-inflammatory effects. It highly expresses in the cerebral tissue, cerebrospinal fluid and peripheral blood serum after cerebral ischemia. IL-6 plays an important role in the pathophysicoloy and inflammatory response to the ischemia cerebrovascular disease of acute stage. CONCLUSION: IL-6 plays an important role in the pathophysicological mechanism and prognosis of ischemic cerebrovascular disease, which can be taken as a prediction index for evaluating the focus of infection and neurofutional defects.

Objective To study the role of N‐acetylcysteine (NAC) in protecting rats against con‐trast‐induced acute kidney injury .Methods Forty‐five adult Wistar rats were randomly divided into control group ,model group and NAC group (15 in each group) .Their serum levels of creati‐nine ,CRP ,TNF‐a were measured before ,and 48 and 72 h after contrast medium injection .The an‐imals were killed 72 h after contrast medum injection .Their serum levels of malondialdehyde , SOD ,NO were measured .Eexpressions of Bax and Bcl‐2 were detected .Results The serum levels of creatinine ,CRP ,TNF‐a ,malondialdehyde and the expression level of Bax were significantly higher in model group and NAC group than in control group ,and in model group than in NAC group after contrast injection (P< 0 .05) .The serum levels of SOD and NO and the expression level of Bcl‐2 were significantly lower in model group and NAC group than in control group ,and in model group than in NAC group after constrast injection (P< 0 .05) .Immunohistochemistry demonstrated that the TGFβ1 expression level was significantly higher in model group and NAC group than in control group and was significantly lower in NAC group than in model group .Con‐clusion NAC can protect rats against kidney injury and reduce contrast‐induced acute kidney in‐jury by inhibiting inflammation ,oxidation ,apoptosis and cytokines .

Objective To studytherelationshipbetweenhypercortisolismand psychosis. Methods According to pathologic diagnosis, 133 cases of hypercortisolism were dividedinto adrenal lesion group, pituitary adenoma group and ectopic ACTH tumor group, and the relationship between hypercortisolism and psychosis was analyzed. Results (1) There were significant differences between groups regarding cortisol levels and the amplitude of fluctuation. (2) Depression and mania were the main manifestations of psychosis in the patients, and 79.7% of the patients showed symptoms of depression. (3) In ectopic ACTH tumor group, the level and the increased amplitude of 24 h urinary free cortisol were significantly higher than those in the other two groups, all the patients had severe depression, and the rate of suicide tendence (58.3%) was significantly higher than the other two groups. Conclusions (1) Psychosis has a close relationship with hypercortisolism,especially with the marked fluctuation in cortisol level. (2) Sufficient attention should be paid to this relationship, which will improve the diagnosisand treatment of hypercortisolism.

Objective To detect the renal reserve in senility and deduce the clinic significance.Methods The glomerular filtration rate and filtration fraction were measured in 43 healthy citizens before and after infusion 18-amino acid to investigate the renal functional reserve.Results Before infusion the amino acid,the range of GFR basal value of senile persons was(58～101)ml/min 1.73m 2 mean value was(76?8.5)ml/min 1.73m 2.And after the amino acid infusion,the GFR value was (65～128)ml/min 1.73m 2,mean value was (103?8.1)ml/min 1.73m 2,there was obviously elevation (P

Objective To evaluate the correlation between high-sensitivity C-reactive protein(hsCRP)and neutrophil alkaline phosphataee(NAP).Methods 74 patients with different hsCRP levels and 20 healthy subjects were selected.hsCRP and NAP were detected in every person,then the t test and correlation analysis were conducted.Results The NAP integral value of high-value hsCRP group and mid-value were significantly higher than the low-value hsCRP group(P ＜ 0.01),and the NAP group average positive rate of the high,median hsCRP values were 81.8％and 82.3％,which were higher than low-value of hsCRP group(53.6％).Compared the correlation between each group of hsCRP value and integral value of NAP,the hsCRP of high-value hsCRP group has a good correlation with NAP integral value(P ＜ 0.01),while the hsCRP of mid-value of hsCRP group and NAP integral is less relevant(P ＞0.05).Conclusion hsCRP as an acute reactive protein exists a good correlation with NAP,when hsCRP ＞ 50mg/L,it can partially replace NAP.

Objective To investigate and compare the clinical feature and natural course of polycythemia vera(PV)between Uygur and Han nationalities in Xinjiang Uygur Autonomous Region.Methods Clinical symptoms,signs,laboratory tests and prognosis of 37(20 Han,13 Uygur,4 other nationalities)patients with PV were analyzed.Results There were 22 males and 15 female.The mean age of all patients was 59.41±11.31(31-85)years old.The mean hemoglobulin level was(191.11±21.41)g/L.Erythremia combined with leukocytosis or thromboeytosis were observed in 23(62.2%)or 19(51.4%)patients respectively.Splenomegaly was found in 27(73.0%)patients and hepatomegaly in 9(24.3%).Serum LDH was elevated in 28(75.7%)patients.Twenty two patients(59.5%)had vascular thrombotic events.Two patients developed MF.N0 secondary neoplasm was identified.Two patients died of thrombosis.Over 60 years old,leukocytosis and thrombocytosis were the high risk factors associated with thrombosis.No significant differences of clinical manifestations and thrombotic events have been found between Uygur and Han patients in Xinjiang.Conclusion Over 60 years old,leukocytosis and thromboeytosis were probably the high risk factors of thrombosis in PV patients.There was no significant differenee in clinical feature and natural course of PV between Uygur and Han nationalities in Xinjiang Uygur Autonomous Region.
