Ghrelin is a small active peptide secreted by gastric fundus cell. As an endogenous ligand of growth hormone receptor,it helps to promote growth hormone secretion,increase food intake and participate in energy metabolism. Recently,studies have indicated that Ghrelin,together with other peripheral signals,participate in the regulation of glucose and lipid metabolism. Insulin resistance (IR) is an important pathophysiological basis of the development of type 2 diabetes mellitus (T2DM),while obesity is the common risk factor of both IR and T2DM. It has been confirmed that Ghrelin has a close and complex connection with obesity and T2DM. Further study about Ghrelin may open up a new way to the diagnosis and treatment of obesity and T2DM.

Methods The plasma PAI 1 activity, by means of chromgenic substrate assay, and the sequence polymorphisms of 4G/5G in promotor region and (CA)n dinucleotide repeats in the 4th intron of PAI 1 gene, by amplified fragment length polymorphism assay, were measured in 50 patients with first ever cerebral infarction (FCI), 45 patients with RCI and 60 healthy controls.Results The plasma PAI 1 activities in both FCI patients (1.13?1 1 AU/ml) and RCI (1.13?0.150 AU/ml) were remarkably higher than that in the controls (0.7?0.25 AU/ml) (both P

Objective To investigate the effects of ultra-filtration extract from the mixture of Angelicae Sinensis Radix and Hedysarum Polybotrys (UFE-AH) on the expressions of HSP70 and eNOS in H2O2-induced endothelial cell apoptosis. Methods H2O2 induced ECV-304 cell apoptosis to prepare models. The experiment was divided into normal control group, model group, simple medicine group, medicine intervention group, and all treatment groups received relevant medicine for intervention. Flow cytometry (FCM) was used to detect apoptosis and concentration of intracellular Ca2+;RT-PCR was used to detect the mRNA expression of HSP70 and eNOS;Western blot was used to detect the expression of HSP70 protein;Nitrale reduetase and spectrophotometric method were employed to detect the content of NO. Results Compared with normal control group, cell apoptosis rate, concentration of intracellular Ca2+, and expression of HSP70 increased significantly in model group (P<0.05);gene expression of eNOS mRNA and content of NO decreased (P<0.05). Compared with model group, cell apoptosis rate and concentration of intracellular Ca2+dropped in medicine intervention group (P<0.05);expressions of HSP70, eNOS mRNA and content of NO increased (P<0.05). Conclusion UFE-AH can confront H2O2-induced cell apoptosis H2O2 of ECV-304 human umbilical vein endothelial by increasing the expressions of HSP70 and eNOS and content of NO, and reducing the intracellular calcium overload.

Objective: To explore the effects of ulinastatin on the level of MIF in rats with acute necrotic pancreatitis. Method: 52 healthy Wister rats were randomly divided into three groups: normal control group(group C, 12), ANP group(group A, 20)and UTI group(group U, 20). Severe acute pancreatitis rat model in group A were induced by injection of 315 % sodium taurocholate through retrogradely common biliopancreatic ducts via papilla duodeni. After inducing the rat model of ANP through the way above, rats in group U were treated by ulinastatin through portal vein injection. Pancreas and duodenum were only flipped after opening abdominal cavity in group C. Then rats were killed at 3rd, 6th ,12th ,24th hour after operation respectively. Cut the belly open at once, and draw blood in postcava. The levels of serum MIF were determined with ELISA. Blood amylase was detected through biochemistry instrument. Resected pancreas tissues was scored according to the standard of Kusske. Result: Compared to the normal control group, the level of serum MIF , blood amylase and histopathological scores were significantly increased in ANP group, P

Objective To explore the intervention effect of active fraction of Angelica Sinensis Radix in mice under high altitude hypoxia condition. Methods Totally 72 healthy SPF mice were randomly divided into control group (K), model group (M), Rhodiola rosea group, and active fraction of Angelica Sinensis Radix groups (B, C, X). The mice were administerted corresponding treatment by gavage for 21 days. Control mice were given normal saline in same volume. From the 8th day, all mice excepted control mice were exposed to high altitude hypoxia cabin after 0.5 hour gavage treament. On the 22nd day, after got out of the cabin and their body weight were measured, mice were put to death through eyeball blood sampling to prepare splenic lymphocyte suspension. The proliferation and transformation capacities of lymphocyte cell and killing activity of NK cells were detected by MTT. The content of IL-2 in the serum of mice in each group were detected by ELISA. Results Compared with the control group, the body weight of mice, the proliferation and transformation capacities of lymphocyte cell, the killing activity of NK cells, and the content of IL-2 were all significantly decreased (P<0.05, P<0.01). Experiment tests showed that the proliferation and transformation abilities of lymphocyte cell and the killing activity of NK cells were all increased in the mice of group B, C, and X compared with those of the model group (P<0.05, P<0.01). The stimulate index of lymphocyte cell was raised after X intervention compared with those of the model group (P<0.05). The content of IL-2 in the serum was enhanced after intervention of active fraction C and X of Angelica Sinensis Radix compared with those of the model group (P<0.05, P<0.01). Conclusion Active fraction of Angelica Sinensis Radix shows increasing immunological function of mice exposed to hypoxia.

This study was designed to investigate the impact of ultra-filtration extract mixture from Astragals mongholicus (UEMAM) o radiosensitivity of H22 ascitic tumor in mice to 12C6+ ions radiation. The H22 ascitic tumor model was established in mice by intraperitoneal injection of 0.2 mL H22 ascitic cells. The animals were subsequently divided into 4 groups randomly, treated with normal saline, UEMAM, heavy ion beam radiotherapy and UEMAM plus heavy ion beam radiotherapy, respectively. The body weights, abdomen circumference of the mice were measured and the mouse behavior was monitored every day; survival time was recorded to evaluate life extension effect; flow cytometry technique was used to detect H22 cell apoptosis and cell cycle; protein levels of p53, Bax, Bcl-2 and cleaved Caspase-3 were analyzed by Western blot; the single cell gel electrophoresis was used to detect the level of deoxyribonucleic acid damage (DNA damage). The results suggest that UEMAM significantly increased survival time, and decreased body weights and abdomen circumference over the saline control group. The treatment increased cell apoptosis, cycle arrest and DNA damage compared to the saline control group. UEMAM significantly enhanced the therapeutic effect of heavy ion beam radiation in survival time, and decreased body weights and abdomen circumference in the tumor-baring mice. The combination increased cell apoptosis, cycle arrest and DNA damage compared to the radiotherapy group. The results of Western blot suggest that the treatment significantly enhanced p53-induced apoptotic signals. The experiment discovered that UEMAM could improve radiosensitivity of H22 ascitic tumor through activation of p53-mediated apoptotic signal pathway.

BACKGROUND: It remains poorly understood whether anterior column quadrilateral wing plate exists to solve intraoperative multiple plastic and quadrilateral in vivo shift for treating acetabular anterior column and acetabular quadrilateral body fractures.OBJECTIVE: To figure out the promising application on measurement of anatomical character parameters when designing acetabular anterior column and acetabular quadrilateral body using Mimics software. METHODS: 60 pelvic CT scan data were collected and three-dimensionally reconstructed by Mimics software. The following anatomical character parameters were measured, including the angle between plane of arcuate line of true pelvis and plane of quadrilateral surface, the four boundary lines of quadrilateral body, and the thickness of substance of bone in quadrilateral region. The projection curve on quadrilateral surface of acetabular margin and dangerous zone for screw placement were both drew. Above all, the study attempted to find out the proper safe entry point of quadrilateral screw and to measure their leaning inside angles.RESULTS AND CONCLUSION: (1) The angle between plane of arcuate line of true pelvis and plane of quadrilateral surface was not significantly different between males and females. (2) The minimum thickness of quadrilateral body in males was larger than that in females. (3) The maximum leaning angle flapper plate screw P1 and P2 for quadrilateral body was significantly smaller in males than in females, but that of screw P3 was not significantly different between males and females. (4) The application of Mimics software made it easier, more intuitive and more practical for the design or development of new plate for acetabular anterior column and acetabular quadrilateral body. The common points and difference between acetabular anterior column and acetabular quadrilateral body could be specifically described by the new anatomical character parameters, which are defined by bone surface features of pelvis.

Objective:To investigate the clinical value and safety of ultrasound guided percutaneous transhepatic gallbladder puncture and drainage (PTGBD) in the treatment of pregnancy combined with acute biliary pancreatitis (ABP).Methods:The clinical data of 47 pregnant combined with ABP from 2010 to 2019 in Shengjing Hospital of China Medical University were retrospectively analyzed. Among them, 19 patients received regular medication (conservative group), and the other 28 patients received PTGBD (PTGBD group). Clinical indexes of two groups including acute physiology and chronic health evaluation acute physiology and chronic health evaluationⅡ(APACHEⅡ), serum amylase, white blood cell and total bilirubin were respectively recorded before and 3 days after treatment.Results:There were no statistical difference in the indexes before treatment between 2 groups ( P>0.05). The APACHE Ⅱ, serum amylase, white blood cell and total bilirubin after treatment were significantly lower compared with those before treatment, conservative group: (5.9 ± 1.9) scores vs. (7.2 ± 1.3) scores, (736.8 ± 64.2) U/L vs. (969.2 ± 124.3) U/L, (10.3 ± 1.4) × 10 9/L vs. (14.7 ± 2.1) × 10 9/L and (55.3 ± 9.5) mmol/L vs. (67.1 ± 10.2) mmol/L; PTGBD group: (4.1 ± 1.7) scores vs. (7.0 ± 1.2) scores, (465.5 ± 77.9) U/L vs. (1 001.8 ± 112.5) U/L, (8.4 ± 2.2) × 10 9/L vs. (13.5 ± 2.6) × 10 9/L and (38.4 ± 10.6) mmol/L vs. (73.7 ± 12.5) mmol/L, and the indexes in PTGBD group were statistically lower than those in conservative group, and there were statistical differences ( P<0.05). In conservative group, 5 cases died (both mother and infant) after deterioration of the condition and 1 infant died after birth. In PTGBD group, 3 cases died (both mother and infant) after deterioration of the condition and 1 infant died after birth. The maternal cure rate and fetal survival rate in PTGBD group were statistically higher than those in conservative group PTGBD: 89.3% (25/28) vs. 14/19 and 85.7% (24/28) vs. 13/19, and there were statistical differences ( P<0.05). Conclusions:Among patients with pregnancy combined with ABP, early PTGBD is more effective than conservative medication, and quickly relieves symptoms and reduces complications.
