14-3-3 protein is a highly conserved soluble acid family. Recent researches suggest that they play critical regulatory roles in cellular processes such as cellular mitosis,growth,differentiation,proliferation and death,etc.14-3-3sigma protein,one member of the family,expresses mainly in epithelial cells and has histological specificity.14-3-3sigma protein interacts with several signal transduction proteins,induces cell cycle arrest in G2 phase after DNA damage,and regulates cellular biological functions.Abnormal expression of 14-3-3? sigma protein is common during tumor transformation,which may be induced by p53 mutation or CpG island hypermethylation of promoter. It is closely related with the transformation,progress and prognosis of human malignant tumors.

The polymorphisms of paraoxonase 1 ( PON 1 ) and ApoE gene in 192 patients with type 2diabetes mellitus (DM group) , 116 cases of atherosclerosis (AS) without DM (AS group), and 105 normal subjects (NC group ) were detected by means of PCR-restriction fragment length polymorphism. The serum concentration of Ox-LDL was determined by enzyme linked immunosorbent assay. The results showed that plasma Ox-LDL level in DM group was higher than those in AS and NC groups[(754.2±279.9 vs 526. 1±186.2 and 421.1 ± 163.2 )μg/L, P<0.01]. Ox-LDL level in the patients with QQ genotype of PON 1 was higher than those in QR and RR genotypes in type 2 DM[(846.6±147.5 vs 763.4±126. 7 and 7 1 3.2 ±132.4 ) μg/L, P<0. 0l],and Ox-LDL level in the patients with ε3/4+ ε4/4 genotype of ApoE was also higher than those in ε3/3 and ε2/2 + ε2/3 geneotypes in type 2 DM[( 824.3 ± 173.5 vs 741.6± 182. 5 and 718.3 ± 167.5 ) μg/L, P<0.05], but the difference was not found in atherosclerosis without DM. Multiple regression analysis showed that disease duration, PON1 and ApoE genotypes were the independent predictors of plasma Ox-LDL level in patients with type 2 DM.

Stratum corneum,the outermost layer of the mammalian skin, has its unique structural,biophysical and biochemical characteristics.The form of stratum corneum is a continuous sheath of protein-enriched corneocytes embedded in an intercellular matrix enriched in nonpolar specialized lipids.It provides an impermeable barrier from exogenous noxious substances and prevents the body from transdermal water loss.Recent researches suggest that its morphological and functional abnormalities can be induced by various environmental effects such as ultraviolet radiation,mechanical friction,organic solvents,etc.However,the mechanism of the injury-repair process remains unclear.Several cytokines and ceramide may be involved in the regulation.

Objective To study the regional cerebral glucose utilization with 18 F-fluorodeoxyglucose (FDG) PET and to investigate the correlation between cerebral glucose metabolism and the clinical characteristic of progressive supranuclear palsy (PSP).Methods A total of 13 patients with PSP and 30 matched healthy controls were performed 18F-FDG PET imaging at rest state.Visual inspection and statistical parametric mapping (SPM) were used to investigate regional cerebral metabolic rate of glucose (rCMRglc).Results Based on the visual inspection,PET imaging in the PSP patients showed that the focal hypometabolic areas mainly included the bilateral frontal cortex,midbrain and subcortical structures.Compared to the controls,voxel-based analysis showed that the regional glucose metabolism decreased in bilateral superior,middle frontal gyrus,cingulate gyrus,midbrain and subcortical structures including basal ganglion and thalamus,which were consisted with the clinical characteristics,such as vertical gaze palsy,pseudobulbar palsy,postural instability,axial rigidity,dementia and so on.Conclusion 18 F-FDG PET imaging is helpful for the early diagnosis of PSP.

AIM: To evaluate the effect of simvastatin on the left ventricular mass in patients with essential hypertension (EH). METHODS: 50 patients with hypertension without severe complication were randomly divided into two treatment groups: combination treatment group and hydragogue group, and 25 normal subjects without any treatment were taken as the control. The 25 patients in combination treatment group were given simvastatin and hydragogue for 12 weeks while the other patients in hydragogue group were given hydragogue during the same time. The left ventricular mass was examined from ultrasonography in all patients before and after treatment. RESULTS: The left ventricular mass index (LVMI) was higher in the two treatment groups of patients (133.61±31.02, 118.04±39.62 g·m-2) than that in the control group (88.79±22.73 g·m-2) before treatment (P<0.01, 0.0001, respectively) while the blood pressure was higher. There was no significantly difference in age, serum concentrations of total cholesterol or triglyceride, sugar and blood pressure between the two treatment groups and the control group (P>0.05). There was no significant difference in all variables between the two treatment groups before treatment. After treatment, the LVMI was decreased (133.61±31.02 vs 91.07±16.01 g·m-2, P<0.01) in the combination treatment group while there was no significant change in LVMI in the hydragogue group compared with the control group. The blood pressure in the two treatment groups was decreased to the normal. Compared with hydragogue group, the change of LVMI was higher in the combination group though the serum concentrations of total cholesterol, triglyceride or sugar were not significantly different. No significant change in serum concentrations of total cholesterol, triglyceride or sugar was found during treatment in the two groups. The change of LVMI did not correlate with the change of blood pressure, serum concentrations of total cholesterol , triglyceride or sugar in the combination treatment group(P>0.05). CONCLUSION: Being independent of the changes of serum concentrations of total cholesterol, triglyceride or sugar and blood pressure, simvastatin can inhibit the increase of left ventricular mass in patients with essential hypertension.

Objective This study was designed to determine the influence of acute ethanol intoxication (AEI) on brain edema and aquaporin-4(AQP-4) levels after traumatic brain injury(TBI) in rots. The underlying mechanism was also investigated. Method Severe traumatic brain injury models were made using the Feeny method; acute ethanol intoxication models were established by gavagy. One hundred and ninety-two male SD rats were randomly divided(random number) into four groups, namely the sham operation group(A ), the acute ethanol intoxication group( B ), the traumatic brain injury group(C) and the combination of acute ethanol intoxication with traumatic brain injury group(D). Each group was further divided into four sub-groups according to the time interval between injury and death of the rats. After brain tissue was fixed by affusing paraformaldehyde, the expression of AQP-4 was detected by immunohistochemistry. Water content was detected by dry-wet analysis, and AQP-4 mRNA and protein were detected by RT-PCR and western blotting respectively after the brain tissue was got by rapid decapitation. Data were analyzed by one-way ANOVA. Results The water content of brain tissue and expression level of AQP-4 were not significantly different between groups A and B( P > 0.05); however both were significantly increased in groups C and D relative to group A( P < 0.05). The water content of brain tissue in group D increased by mere than that in group C( P < 0.05), while the expression level of AQP-4 in group D was lower than that in group C(P<0.05). Conclusions Acute ethanol intoxication inhibited the expression of AQP-4,which induced a more severe cerebral edema after traumatic brain injury.

Objective To dynamically observe the effect of mild hypothermia on concentration of plasma S-100B protein in patients with acute severe brain injuries so as to further explore its role in treat-ment of acute severe brain injury. Methods A total of 120 patients with acute severe brain injuries were randomly divided into mild hypothermia group and general group. The patients in mild hypothermia group were treated with mild hypothermia besides conventional therapy, with maintenance of rectal tem-perature at 33℃-35℃ for 3-5 days. Serial concentration of S-IOOB protein in serum was measured in all patients from 6 hours to 6 days after hospitalization. GOS evaluation was done three months after treat-ment. Results The concentration of S-100B protein in serum of mild hypothermia group and general group was significantly higher than of normal group (P <0.05), with significant lower level in mild hypo-thermia group than general group(P <0.05). Mild hypothermia could improve prognosis of patients with acute severe brain injury. Conclusions Early use of mild hypothermia can decrease concentration of S-100B protein in serum, protect neurofunction and improve prognosis, as may be related to its function in alleviating damnification brain cell inflammation reaction mediated by S-100B protein.

Objective To study the characteristics of respiratory impedance in patients with chronic obstructive pulmonary disease (COPD),obstructive sleep apnea hypopnea syndrome (OSAHS).Methods The respiratory impedance were measured by Impulse Oscillometry(IOS) technique and polysomnography(PSG) were done synchronously in 11 COPD patients,15 OSAHS patients,4 overlap syndrome patients(COPD+OSAHS) and 10 control group. Results Zrs、R5、Rc and RP in COPD group,OSAHS group and COPD+OSAHS group were higer than those in contml group.Zrs、R5、R5-20、Fres.Rc and Rp in COPD group and COPD+OSAHS group were significantly higerthan those in OSAHS group.R20 and Rc in OSAHS group were higher than those in COPD group and control group (P<0.05).Rc in OSAHS group was still significantly higher than that in COPD group (P<0.05). The level of sleep efficiency was positive correlated with FEVl/pre% of COPD(r=0.632),while the levels of rouse frequence (r=-0.672),time of SaO2 <90% (-0.868) and ODI (-0.846) were negative correlated with FEVl/pre% of COPD.Condusion For OSAHS patients, there is some dysfunction in peripheral airway tract;For COPD patients,ODI and time of SaO2<90% are good index for the severity of disease.
