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.

[Objective] To study the effects of different growth periods on the contents of volatile oil and the curcumol in Curcuma aromatica Salisb. samples,which provided theoretical bases to control the quality of the crude drug of Curcuma aromatica Salisb.[Method]The contents of volatile oil in Curcuma aromatica Salisb. samples were determined by the method of Pharmacopeia,and HPLC method for determination of curcumol in different samples was established. [Result]The contents of volatile oil in different samples lied in the range of 0.820%～0.471%(g/g),and the contents of curcumol in different volatile oil samples were between 0.862%(g/g) and 1.380%(g/g). [Conclusion]Compared with the Curcuma aromatica Salisb. of a shorter growing period,the contents of longer growth period were higher.Different growing time had effects on the accumulating of volatile oil and the curcumol in Curcuma aromatica Salisb.

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 summarize the characteristics of multi-slice computed tomography (MSCT) of portal vein diseases and investigate the CT diagnosis of its primary and secondary diseases.Methods The imaging data of 62 patients from Xi'an Xidian Group Hospital,28 patients from Nuclear Industry 215 Hospital of Shanxi Province and 16 patients from Xi'an Gaoxin Hospital with portal vein diseases from January 2012 to March 2015 were retrospectively analyzed.The CT findings,primary and secondary diseases of portal vein lesions were recorded through plain scan and enhanced scan of MSCT.Results Changes in the width of portal vein:among 106 patients,dilation of main portal vein was detected in 45 cases,stenosis of stem or branches of portal vein in 39 cases,portal vein obstruction in 49 cases (21 patients accompanied with enlargement in stem of portal vein and 6 patients with normal width).The diameters of dilated portal vein were 1.4-2.2 cm with a mean diameter of 1.8 cm.The diameters of portal vein with stenosis and occlusion caused by carcinomas were 1.8-4.0 cm with a mean diameter of 2.3cm.Portal vein fistula and pneumatosis:hepatic artery-portal vein fistulas were detected in 12 patients,posterior right branches of portal vein-inferior vena cava fistulas in 2 patients,inferior vena cavaportal vein fistulas and portal-hepatic vein fistulas in 2 patients,pneumatosis in 2 patients.Lesions of portal vein occlusions:occlusions located at main portal veins were detected in 4 cases,left and right branches in 34 cases,both main portal veins and left or right branches in 11 cases.Malignant stenosis and occlusion were detected in 29 and 42 cases,benign stenosis and occlusion were detected in 10 and 7 cases,respectively.Protopathies of portal vein dilation:there were 43 patients with liver cirrhosis and 2 patients with inferior vena cava-portal vein-hepatic vein fistula of Budd-Chiari syndrome.Protopathies of benign stenosis and occlusion:portal vein thrombosis in liver cirrhosis,giant cavernous haemangioma,polycystic disease of liver,pylephlebitis caused by liver abscess,portal vein thrombosis caused by polycythemia vera.Protopathies of hepatic artery portal vein fistula and portal veininferior vena cava fistula:liver cancer and liver cirrhosis,protopathy of inferior vena cava-portal vein fistula and portal vein-hepatic vein fistula were Budd-Chiari syndrome.Protopathies of pneumatosis:intestinal infarction after superior mesenteric artery embolus and acute gastric dilatation.Portacaval collateral circulation occurred in 58 patients (partial patients complicated with multi-point varices and shunts),ascites in 44 patients,portal vein cavernous transformation in 12 patients,ischemia and edema of intestinal wall in 5 patients,intrahepatic cholangiectasis in 19 patients including 17 cases of biliary obstruction caused by malignant tumors and 2 cases of portal vein cavernous transformation complicated with intrahepatic cholangiectasis (portal hypertensive biliopathy).Conclusions The MSCT for portal vein diseases is presented as portal vein stenosis,occlusion or dilation,pneumatosis.Secondary lesions are portacaval collateral circulation,portal vein cavernous transformation,intestinal ischemia and portal hypertensive biliopathy,and primary lesions are mainly liver cirrhosis and malignant tumors.MSCT can show clearly the portal vein lesions and diagnose accurately its primary and secondary lesions.

Objective To evaluate the effect of deferoxamine on learning and memory ability in aged rats.Methods Forty-two healthy male Sprague-Dawley rats,aged 18 months,weighing 450-550 g,were randomly divided into 2 groups (n =21 each) using a random number table:normal saline group (group N) and deferoxamine group (group D).In group D,deferoxamine 150 mg/kg was injected intraperitoneally once a day for 6 consecutive days,while the equal volume of normal saline was given instead in group N.Morris water maze test was conducted at 2 h after each injection on that day,lasting for 6 days.The escape latency,swimming speed,time of staying at the original platform quadrant and time spent in the central region were recorded.Hippocampal ferritin expression was detected by Western blot before the first administration and at 2 h after 3rd and 2nd administration.Results Compared with group N,the escape latency was significantly shortened,and the percentage of the time of staying at the original platform quadrant and time spent in the central region was increased,the expression of hippocampal ferritin was down-regulated,and no significant change was found in the swimming speed in group D.Conclusion Deferoxamine can enhance the learning and memory ability in aged rats,and reduced iron deposition in hippocampi is involved in the mechanism.

Objective To evaluate the security of inspiring high concentration oxygen by detecting the reactive oxygen species of the rats brain homogenates after inspiring high concentration oxygen for a certain time.Methods Sixty wister rats weighting 150~200g were randomly devided into five groups(the group of 4h、8h、12h、16h and the control group,12/group).The experimental rats were exposed to 85%~100% oxygen in a self-made chamber and the control animals were kept in normal room air.The Concentration of the MDA,SOD,GSH,NO,NOS,CAT and T-AOC of the brain homogenates was detected.Results Compared with the control group,the level of MDA,NO and NOS in the brain homogenates grew up markedly(P

Objective To study the anatomic characteristics of the infraorbital ethmoid cells on muhislice CT(MSCT)and explore the relationship between the infraobital ethmoid cells and mueosal swelling of sinuses.Methods Two hundred sixty patients(520 sides) of consecutive axial scans by GE HisDeed VCT and the multiplunar reformation(MPR),virtual endoscopy(VE)reconstruction images by GE AW 4.2 workstation were reviewed retrospectively.The following CT features were assessed:(1)the anatomic characteristics of the infraobital ethmoid ceils,including the frequency of identification,origin,classification.(2)presence of mucosal swelling of sinuses,(3)the maximal transversal diameter of the inflraobital ethmoid cells in ostium of maxillary sinus(perpendicular to the uncinate process),and the diameter of the ostium of maxillary sinus,(4)presence of infraobital ethmoid ceils inflammatory findings and a contact between the mucosal surface of the ostium of maxillary sinus.The results were analyzed by using Chi-square test and logistic regression analysis with the statistical software SPSS 11.5.Results (1) UniLateral infraobital ethmoid cells were f10und in 68 patients(26.1%),and bilateral infraobital ethmoid cells were found in 81 patients(31.2%).Infraobital ethmoid ceHs were found in 230 sides on left Bide (120 sides)and right side(110 sides).(2)Infraobital ethmoid cells originated from the anterior ethmoid cells in 124 sides(53.9%)and from posterior ethmoidal cells in 62 sides(27%),originated from both the anterior ethmoidal cells and the posterior ethmoidal cells in 44 sides(19.1%).(3)The classification of the infraobital ethmoid cells included three types.Infraobital ethmoid cells with different origination differed significantly in theirtypes(x2=193.433,P<0.01).Most ofthe infraobital ethmoid cells originated from tlle anterior ethmoidal cells were type Ⅰ(160 sides),while the type Ⅱ(48 sides)and Ⅲ(45 sides) frequently originated from the posterior ethmoidal ceHs(4)The mueosal swelling of sinuses,were found in 165 sides in presence of infraobtial ethmoid cells and 192 sides in absence of infraobtial ethmoid cells.The presence of infraobtial ethmoid cells had no effect on mucosal swelling(X2=1.824,P>0.05).The maximal transversal diameter of the infraobital ethmoid cells in ostium of maxillary sinus did not differ significantly between the cases with or without mucosal swelling of sinuses(t=0.273,P>0.05).and the diameter of the ostium of maxillary sinus were not significantly related with mucosal swelling of sinuse8 (Wald=2.534,P>0.05).Presence of infraobital ethmoid cells inflammatory findings (Wald=10.817. P<0.01,OR=4.125)and a contact between the mucosal surface of the ostium of maxillary sinus (Wald= 6.640,P<0.01,OR=3.728)were significantly related to mucosal swelling of 8inuses. Conclusions (1)MSCT scan could clearly demonstrate the detailed information of infraobital ethmoid ceIIs.(2)The presence of infraobtial ethmoid cells Was not a risk factor for chronics sinusitis. When we assess inflraobtial ethmoid cells as a possible etiologic factor in chronics sinusitis we should observe presence of infraobital ethmoid cells inflammatory findings and a contact between the mucosal surface of the ostium of maxillary sinud.

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.
