The changes of rheobase(Rh), chronaxie(Chr), standard electrical quantity(a) and mtensity-duration curve(i. t. c) were studied for understanding the effect of aging on the excitability of sciatic and caudal nerves in Wistar rats of different age. The results show that before grown-up excitability of the peripheral nerves increases progressively with age, after that it tends to decrease. Chronaxie as an index can not reflect the change of excitability of the peripheral nerves correctly.

Objective To investigate the effects of desflurane inhalation on pulmonary alveolar-capillary membrane permeability and the inflammatory cell counts in broncho-alveolar lavage fluid (BALF) during endotoxin-induced acute lung injury in rats. Methods Forty-eight Wistar rats weighing 200-290 g were anesthetized with intraperitoneal pentobarbital 100mg?kg-1 , tracheotomized and mechanically ventilated. PETCO2 was maintained at 35-45 mm Hg (VT 8 ml?kg-1 , RR 65-70 bpm). Right carotid artery and left femoral vein were cannulated for BP monitoring and fluid and drug administration. The animals were randomly divided into four group with 12 animals in each group : (1) control group received normal saline (NS) 1.2 ml i.v. followed by 4 h mechanical ventilation; (2) LPS group received LPS (055:B5, Sigma) 5 mg?kg-1 followed by 4h mechanical ventilation; (3)Desflurane group A and B received LPS 5 mg? kg-1 followed by desflurane inhalation for 4 h at 1 MAC (desflurane group A) or 1.5 MAC (desflurane group B) . Six animals in each group received Evans blue 50 mg?kg-1 at the beginning of the experiment for determination of pulmonary alveolar-capillary membrane permeability at the end of the experiment. The animals were sacrificed by exsanguinations at the end of 4h mechanical ventilation. Blood was collected for determination of total plasma protein concentration. Lungs were removed. The right lung was lavaged and BALF was collected for determination of protein content, and differential inflammatory cell counts. The left lung was used for microscopic examination. The morphologic changes were scored 0-3 (0 = normal, 3 = severe morphologic changes). In addition wet/dry lung weight ratio, pulmonary permeability index (BALF protein concentration /total plasma protein concentration?10-3 ) and mortality rate were also determined. Results In group 3 (desflurane 1 MAC) W/D lung weight ratio and lung water content significantly increased compared with those in LPS group. In group 4 ( desflurane 1.5 MAC) W/D lung weight ratio, lung water content, pulmonary permeability index, Evans blue content in lung tissue, morphological change scores and mortality rate were all significantly increased compared with LPS group (group 2). There was no significant difference in total and differential inflammatory cell counts in BALF between group 2 and 4.Conclusion Desflurane inhalation is detrimental to the lungs acutely injured by endotoxin in a dose-dependent manner.

In the past few years,it has been disclosed that identified epigenetic processes and epigenetic changes are involved in human diseases.Disorders of these processes may influence chromatin structure and gene expression,which may result in complicated syndroms,multiple-factor diseases and cancers. The researchprogress of epigenetic processes of several diseases is reviewed in this paper.

Objective To investigate the relation of the expressions of matrix metalloproteinase-2(MMP-2)and-9(MMP-9)with polymyositis/dermatomyositis(PM/DM).Methods Blood samples were obtained from 8 patients with PM,12 patients with DM and 10 normal human controls.Real-time quantitative RT-PCR and Western-blot were applied to examine the mRNA and protein expressions of MMP-2 and MMP-9 respectively in the peripheral blood mononuclear cells(PBMC)of these patients.Results The mRNA expression levels of MMP-2 and MMP-9 in the PBMC of patients with PM or DM were 2.41 and 1.66 folds as high as those of the normal controls,respectively;these difierences were significant between the two groups.Increased expressions of MMP-2 and MMP-9 were also noted in the patients with PM or DM.Conclusion MMP-2 and MMP-9 may play a part in the development of polymyositis and dermatomyositis.

Objective The purpose of this study was to explore the expression of human fibrinogen-like protein 2 (hFgl2) in patients with cryptococcal meningitis (CM).Methods The expression of hFgl2 in the peripheral blood leukocytes from 20 CM cases and 20 healthy individuals,and the expression of hFgl2 in cerebrospinal fluid (CSF) leukocytes in 11 pairs of CM patients and matched controls was detected using immunohistochemical methods.Medical image analysis system (MIAS) was used to analyze the expression of hFgl2 gray values,which were negatively correlated to the expression of hFgl2 protein in both peripheral blood and CSF.Results The average gray values for hFgl2 protein in peripheral monocytes of CM patients and healthy controls were 114.49± 11.82 and 137.56± 10.64,respectively,and those in peripheral neutrophils were 111.71 ± 8.62 and 143.56±12.57,respectively.Compared with the healthy control group,expressions of hFgl2 in peripheral blood monocytes and neutrophils were both significantly increased in CM patients (t =21.21,t=27.19; P<0.01).The average gray values for hFgl2 protein in CSF monocytes from CM patients and negative controls were 115.44±8.67 and 149.25±8.57,respectively,and those in CSFneutrophils were 111.71±8.62 and 143.56 ± 12.57,respectively.The expressions of hFgl2 in CSFmonocytes and neutrophils were significantly increased in CM patients (t =29.95,t=28.87; P<0.01),while the expression intensity of hFgl2 was similar when peripheral blood monocytes and neutrophils compared with their CSF counterparts (t=0.924,t=0.607; both P>0.05).Conclusions hFgl2 can be expressed in both peripheral and CSF monocytes and neutrophils in CM patients.
