Objective To analyze the relationship between the distribution of visceral adipose and cardiovascular damage in the patients with metabolic syndrome. Methods 108 in-patients were categorized according to the diseases, they were suffering from into metabolic syndrome group (MS, 70 cases), essential hypertension group (EH, 22 cases), and type 2 diabetes mellitus group (T2DM, 16 cases). The areas of both visceral adipose (VA) and subcutaneous adipose (SA) were measured for all the three groups, and then VA/SA was calculated. The relationship of the above variables with left ventricular mass (LVM), LVM-index (LVMI) intima-medial thickness (IMT) of carotid artery, and myocardial ischemia was analysed. Results Compared with T2DM and EH groups, the area with VA was significantly larger in MS group (P

Purpose To investigate the expression of c-myc and MDM2 protein in multiple myeloma (MM) and their correlation with clinical stage.Methods Immunohistochemical SP three-step method was used to detect the expression of MDM2 and c-myc protein in 60 cases of MM with different clinical stages and 10 cases of nontumorous bone marrow tissue.Results The positive rate of c-myc protein in MM and nontumorous bone marrow tissue were 71.7％ and 10.0％;the positive rate of MDM2 protein in two tissues were 80.0％ and 20.0％,respectively.The expression difference of two proteins between MM and nontumorous bone marrow tissue was statistically significant (P ＜ 0.05).The expression of c-myc and MDM2 protein was positively correlated with MM clinical ISS stage (P ＜ 0.05),but irrelevant with the age and gender.The expression of c-myc and MDM2 protein in MM was positively correlated (P ＜ 0.05).Conclusion The c-myc and MDM2 protein have a highly expression in MM,and it may be relative to the occurrence of MM and clinical stage.In the MM,c-myc and MDM2 protein may have synergetic functions and promote the development of tumor.

To study the effect of vascular proliferation and reconstruction in chronic hepatitis B (CHB), immunohistochemical staining and in situ hybridization were used. The expression of transforming growth factor (TGF-?1) and smooth muscle actin (?-SMA) in livers of CHB were observed. The results showed that TGF-?1 and ?-SMA were related with degeneration of hepatocytes, intrahepatic vascular fibrosis and hepatic sinusoidal capillarization. The expression degree and range of TGF-?1 and ?-SMA increased with the exacerbation of liver lesion. These results suggest that vascular proliferation and reconstruction may play important roles during the process of CHB.

OBJECTIVE:To study the in vitro dissolution of Enalapril maleate and folic acid tablet. METHODS:HPLC was performed on the column of Agilent HC-C18 with mobile phase A of acetonitrle-phosphate buffer solution(70:30,V/V) and mobile phase B of acetonitrle-phosphate buffer solution(5:95,V/V)(gradient elution) at a flow rate of 1.0 ml/min,detection wavelength was 215 nm,column temperature was 50 ℃,and volume injection was 80 μl. Media were water,hydrochloric acid solution(pH 1.2),phosphate buffer solution(pH 5.0)and phosphate buffer solution(pH 6.8),medium volume was 900 ml and rotation speed was 50 r/min. The dissolution behavior of enalapril maleate in Enalapril maleate and folic acid tablet in 4 media were studied and compared with the dissolution behavior in vitro in original preparation of Enalapril maleate tablet,meanwhile,the dissolution behar-ior of folic acid in Enalapril maleate and folic acid tablet in phosphate buffer solution(pH 5.0)were studied and compared with dis-solution data of folic acid preparation in Japanese Orange Book to evaluate the intrinsic quality. RESULTS:The linear range was 0.561-14.03μg/ml for enalapril maleate(r=0.999 9)and 0.043-1.085μg/ml for folic acid(r=0.999 9),respectively;RSDs of pre-cision and stability tests were lower than 2.0%;recoveries of enalapril maleate in 4 media were 100.63%-102.33%(RSD=0.72%, n=9),99.27%-100.44%(RSD=0.41%,n=9),99.71%-100.29%(RSD=0.15%,n=9)and 96.74%-99.19%(RSD=0.79%,n=9),respectively. Recoveries of folic acid were 100.18%-101.63%(RSD=0.48%,n=9),97.73%-101.81%(RSD=1.32%,n=9),99.60%-102.24%(RSD=0.74%,n=9)and 100.00%-102.76%(RSD=0.90%,n=9),respectively. In 15 min,the dissolution of enalapril maleate of 2 preparations in 4 dissolution media were more than 85%;dissolution speed of folic acid in Enalapril male-ate and folic acid tablet was faster than that in folic acid preparation in phosphate buffer solution(pH 5.0). CONCLUSIONS:The method is suitable to determine the dissolution of Enalapril maleate and folic acid tablet;the in vitro dissolution curve of enalapril maleate in Enalapril maleate and folic acid tablet is similar to Renitec,and the in vitro dissolution of folic acid is better than folic acid preparation.

Objective To observe the effects of electroacupunture (EA) on the abnormal hypothalamus-pituitary-adrenal (HPA) axis and the expression of hypothalamic corticotropin-releasing factor (CRF) peptides family and CRF receptor (R)1 mRNA in traumatized rats,so as to study its underlying mechanism in improving traumatic injury. Methods Forty male Sprague-Dawley rats were randomly divided into normal control group (n=10),normal+ EA group (n=10),surgical trauma (model) group (n=10),and model+EA group (n=10). Traumatic injury model was established by performing an exploratory laparotomy in the rats under anesthesia. EA (2 Hz/15 Hz,1-2 mA) was administered for 30 min via two stainless steel needles inserted in "Zusanli" (ST 36) and "Sanyinjiao" (SP 6). Serum adrenocorticotropic hormone (ACTH) ,corticosterone (Cort),luteinizing hormone (LH) and testosterone (T) contents were detected by double-antibody radioimmnoassay. Hypothalamic CRF and CRF R1 mRNA expression was assayed by reversed transcription polymerase chain reaction (RT-PCR) technique. Results The serum ACTH concentration decreased significantly in model group (P0.05). The serum Cort level increased significantly in model group(P0.05). The expression of hypothalamic CRF mRNA decreased significantly in model group (P0.05). Conclusion EA of "Zusanli" (ST 36) and "Sanyinjiao" (SP 6) can improve surgical trauma-induced HPA disorders,which is probably related to its effects in upregulating CRF mRNA expression and downregulating Ucn 1 mRNA expression in the hypothalamus.

Objective To investigate the surgical procedure selection for chronic pancreatitis.Methods The clinical data of 80 patients with chronic pancreatitis who were admitted to the Peking University First Hospital from January 2000 to August 2013 were retrospectively analyzed.Thirty-eight patients were with or without pancreatic duct stone,and the dilation of the pancreatic duct was above 7 mm,44 patients were with common bile duct dilation,32 patients were with inflammatory mass in the head of the pancreas,and 3 patients were with splenomegaly and esophagogastric varices.Surgical procedures were selected according to the symptoms and results of imaging examination.The remission or recurrence of pain was judged according to the visual analog scales.Patients were followed up via out-patient examination,mail or phone call till December 2013.Results Choledochojejunostomy was done on 27 patients,Partington-Rochelle pancreaticojejunostomy on 24 patients,PartingtonRochelle pancreaticojejunostomy + choledochojejunostomy on 6 patients,pancreaticoduodenectomy on 7 patients,resection of the body and tail of the pancreas on 4 patients,Beger's procedure on 3 patients,splenectomy on 3 patients,Frey's procedure + fenestration of bile duct in the head of the pancreas on 3 patients,Frey's procedure on 2 patients,common bile duct exploration + T tube drainage on 1 patient.The remission rate of abdominal pain was 95.2％ (60/63).One patient died of abdominal infection and multiple organ dysfunction syndrome perioperatively.Three patients were complicated with abdominal infection,2 with pancreatic fistula,1 with biliary fistula and 1 with abdominal bleeding.All the complications were cured by conservative treatment.Seventy-nine patients were followed up,and the mean time of follow-up was 58.6 months (range,4-156 months).Thirty patients had recurrence or new onset of abdominal pain,and the recurrence rate was 38.0％ (30/79).Of the 32 patients with inflammatory mass in the head of the pancreas,17 received choledochojejunostomy,and the recurrence rate of abdominal pain was 9/17 ; the other 15 patients received pancreatoduodenectomy,Beger' procedure or Frey's procedure,and the recurrence rate of abdominal pain was 1/15.Of the 41 patients without inflammatory mass,10 received choledochojejunostomy,and the recurrence rate of abdominal pain was 7/10; 30 received PartingtonRochelle pancreaticojejunostomy,and the recurrence rate of abdominal pain was 33.3％ (10/30).Conclusions Complete drainage could relieve the symptoms for patients with pancreatic duct dilation.Surgical resection or combined surgical procedure is effective for the treatment of patients with inflammatory mass in the head of the pancreas.

AIM: To study effects of hyperbaric oxygen (HBO) and cyclosporin A (CsA) on the contents of active oxygens and nitric oxide (NO) in spleens of skin transplanted mice. METHODS: The donor mice BALB/C and receptor mice Cs7BL/6 were tested for skin transplantation. The HBO group mice were,treated with 99.2 % oxygen under 0.25 MPa for 1.5 hours, while CsA group mice were treated with CsA 0.5 rmg· kg- t· d- 1 by abdomen injection. After 14 days, the spleen were extracted the contents of malondialdehyde (MDA) and NO and the activities of superoxide dismutase (SOD), glutathione peroxidase (GSH - PX), catalase (CAT) and NO synthases (NOS) were determined. RESULTS: (1) Compared with the control group, the transplantation group, HBO group and CsA group have markedly increased the content of MDA and the activities of GSH - PX and CAT; Compared with the transplantation group, the CsA group have markedly increased activity of SOD and reduced activities of GSH - PX and CAT; the HBO group have markedly reduced the activity of GSH - PX and increased the activities of CAT and SOD (P < 0.01 ). (2) Compared with the control group, the transplantation group have markedly increased the content of NO and the activity of NOS; Compared with the transplantation group, the HBO group have markedly increased the activity of NOS and reduced the content of NO ( P < 0.01 ); The content of NO and the activity of NOS in CsA group was not changed significantly. CONCLUSION: In the lymphocytes of the transplantation group, the peroxidation is intensified, and the content of NO and the activity of NOS increased. HBO and CsA may activate the systems of oxidation/antioxidation and NO/NOS in spleen, which may be related to their mechanism of inhibition rejection.

Objective: To study the effects of ginger oleoresins(GO) on blood lipids in hyperlipidemic mice and the platelet aggregation in rats.Methods: The rat platelet aggregation was induced by ADP and AA in vitro, and the inhibition by GO was tested by light transmission. The animal model of hyperlipidemia was establised by feeding Kunmimg mice with high lipid feed stuff. The effects of GO on serum lipid and hepatic MAD in hyperlipidemic mice was investigated. Results: GO could effectively inhibit rat platelet aggregation induced by ADP and AA in vitro, which were 58.9%,97.5% respectively, and in dose dependant manner. Besides, GO could also significantly decrease serum TC, LDL, AS index and hepatic MDA in hyperlipidemic mice, which were 16.45%, 60.45%,37.30% and 54.27% respectively, and showed no side-effect on liver. Conclusion: Long-term consumption of GO can effectively modulate blood lipids, prevent thrombosis and AS.
