OBJECTIVETo explore the effect of electroacupuncture (EA) on the expression of Ghrelin and mRNA expression of its receptor in functional dyspepsia (FD) rats.

METHODSTotally 80 rats were divided into the normal group, the model group, the drug therapy group, and the EA group according to random digit table, 20 in each group. FD model was duplicated by clipping tail modeling. Drug containing cisapride [2 mL/100 g, 0.09 g/(kg x d)] was administered to rats in the drug therapy group from the 3rd day after successful modeling, once per day. EA at Zusanli (ST36) (0.3-0.5 cun) and Taichong (LR3) (0.1-0.2 cun) was performed in the EA group. The twirling of needle was performed to the subsidence of needle, and then the needle was connected to HANS-200A Acupoint Nerve Stimulating Device using disperse-dense wave at 2 Hz, 2 mA, 30 min each time, once per day. Six days consisted of one therapeutic course, two courses in total with an interval of one day. The intestinal propulsive rate of ink was observed. Ghrelin protein expression in gastric tissue was detected by Western blot. mRNA expression of growth hormone secretagogue receptor (GHS-R) in stomach, hypothalamus, and hippocampus was detected using Real-time PCR respectively.

RESULTSCompared with the normal group, the intestinal propulsive rate of ink, Ghrelin protein expression in gastric tissue, mRNA expression of GHS-R in stomach, hypothalamus, and hippocampus decreased in the model group (P < 0.05, P < 0.01). Compared with the model group, the intestinal propulsive rate of ink, Ghrelin protein expression in gastric tissue, mRNA expression of GHS-R in stomach, hypothalamus, and hippocampus increased in the EA group (P < 0.01); mRNA expression of GHS-R in stomach, hypothalamus, and hippocampus increased in the drug therapy group (P < 0.01). Compared with the drug therapy group, Ghrelin protein expression in gastric tissue, mRNA expression of GHS-R in hypothalamus increased in the EA group (P < 0.05, P < 0.01).

CONCLUSIONEA could regulate Ghrelin content and GHS-R mRNA expression of FD rat hypothalamus, hippocampus, and gastric tissue, and promote the intestinal propulsive rate of ink.

Objective: To study the protective effect of Eucommia ulmoides polysaccharide (EUP) on liver-fibrosis rats and investigate its mechanism. Methods: Models of liver-fibrosis rats induced by carbon tetrachlotide (CCl 4) were established by sc injection of pure CCl4 (5 mL/kg) and then peanut oil with 40% CCl4 (3 mL/kg) to the back of rats for eight weeks. After the models were ig administrated by EUP for eight weeks, the indexes of the liver and spleen in liver-fibrosis rats were calculated; ALT and AST activities and contents of TP and ALB in serum were examined; Meanwhile, the ratio between ALB and GLOB (AJG) was computed; The four levels of HA, LN, PCIII, and IV-C in serum of liver-fibrosis rats were determined. SOD activities and Hyp, MDA, and GSH-Px levels in liver tissue were examined; The expression of transforming growth factor-β1 (TGF-β1) in liver was observed. Results: EUP could obviously be against the index increasing of the liver and spleen (P<0.01) in liver-fibrosis rats induced by CCl4; remarkably inhibit the increasing of ALT and AST activities in serum (P<0.01); decrease the content of HA, LN, PCIII, IV-C, and GLOB in serum (P<0.01); increase the content of TP and ALB, and ratio of A/G in serum (P<0.01); decrease the MDA amd Hyp levels in liver tissue (P<0.01); and improve SOD activities and GSH-Px levels in liver tissue (P<0.01); and decrease the expression of TGF-β1 as well. The best effect of EUP was observed in the high-dose group and inhibition of EUP on fibrosis was in a dose-dependent manner. Conclusion: EUP has the remarkable protective effects on liver-fibrosis rats.

Objective To study the application of intensive reduction of blood pressure to the treatment of acute cerebral hemorrhage in elderly patients. Method From January 2006 to December 2007, 40 elderly patients with acute cerebral hemorrhage were enrolled in a randomized and controlled study. Patients were randomly divided into intensive blood pressure reduction group and control group in equal number ( n = 20). The antihyper-tensive agent was used intravenously to reduce the systolic blood pressure to the level lower than 140 mmHg within 1 hour after treatment in patients of intensive blood pressure reduction group, and then the blood pressures was maintained for 7 days.The blood pressure of patients in control group was reduced to that just under 180 mmHg. The size of the haematoma was measured before and 3 days after treatment. The Stroke Scale set by the American National Institutes of Health (NHISS) was assessed before and 7 days and 28 days after treatment,separately. The modified Rankin Scale (mRS) was used to assess the patients 90 days after treatment. The outcomes were statistically analyzed with SPSS version 16.0 software. Measurement data were analyzed with t -test while numeration data were analyzed with chi-square test. Results Before and 3 days after treatment, there was significant difference in size hematoma between two groups (P < 0.05) . Between before and 7 days after treatment, there was significant difference in NHISS scale in intensive blood pressure reduction group (P < 0.05), but there was no significant difference in control group (P > 0.05). Before and 28 days after treatment, there was significant difference in variance of NHISS scale between two groups ( P < 0.05) . Nineth days after treatment, there was significant difference in mild disability and severe disability between two groups ( P < 0.05) . Conclusions Intensive reduction of blood pressure is valid for the treatment of elderly patients with acute cerebral hemorrhage.

Objective To study the effects of Batroxobin( BX) on the intimal proliferation of graft veins. Methods In this study 25 dogs were selected and evenly divided into experimental group, control group and sham operation group. In experiment and control group, a segment of auto- femoral vein were grafted into femoral artery by clean microsurgery technique. In experimental group, BX was given at the dosage of 0. 1 BU/kg, dayly?2 preoperatively, and once a day for consecutive 6 days postoperatively. Plasma NO, ET was determined in the three groups. Computer image analysis system was applied to calculate the thickness of neointima and media in the vein grafts, immunohistochemistry was used to identify PCNA and C-myc. Result The experimental group had a higher level of NO and lower level of ET compared with control group and sham operation group(P 0. 05 ). The PCNA expression in experimental group was statistically different from that of the control group(P

Objective To evaluate the effect of this neuroendocrine hormone on protein expression by treating the human dermal fibroblasts with a-melanocyte stimulating hormone (α-MSH ).Methods Thehuman dermal fibroblasts was cultured, and the total protein of the fibroblasts were separated with immobilized pH gradient-based two-dimensional gel electrophoresis (2-DE). After Coomassie bright blue staining, gel images were acquired by Image-scanner and then analyzed with the PDQuest software. 2-DE maps of fibroblasts were established. Partial differently expressed protein spots were incised from gels and digested by trypsin in-gel. Matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS) and MSDB database searching by Mascot? software were used for protein identification. Results Well-resolved, reproducible 2-DE patterns of dermal fibroblasts treated with and without crMSH were obtained. 8 differently expressed protein spots were detected, among which 8 obtained peptide mass fingerprints (PMF) by MALDI-TOF-MS analysis. Among these proteins, of particular interest were five proteins annexin I, HSP27 and lamin A, etc. Conclusions Proteins expressed by human dermal fibroblasts treated with or without crMSH are different, and some of the differently expressed proteins involve apoptosis, intracellular signal transduction and framework construction and so on, which may be associated with anti-fibrosis effects of (a)-MSH on human dermal fibroblasts.

Objective To explore the bone mineral density (BMD) status and its influencing factors in schizophrenia patients in order to provide basis for risk assessment in psychiatric nursing.Methods A total of 1,139 hospitalized schizophrenia patients were recruited and assigned into the medication group (n=652) and the non-medication group (n=487) according to previous antipsychotic drug history.T-score and Z-score of BMD were determined using Sunlight Omnisense 7000S Bone Densitometry.Blood calcium,blood phosphorus and serum prolactin levels were measured using fasting blood of ulnar vein.Results Differences in age,BMD,milk intake,level of activity,level of smoking,history of fall,history of fracture,serum Ca2+ and PRL were statistically significant between two groups(P＜0.05);there were significant differences in BMD rank distributions among schizophrenia patients with different courses of disease and lengths of taking antipsychotics (P＜0.001);multiple linear regression showed that influencing factors of BMD with statistical significance were courses of disease,lengths of taking antipsychotics,serum Ca2+,serum PRL,milk intake,level of activity,and level of smoking.Conclusion The BMD was lower in the medication group than that in the non-medication group,and the development of osteoporosis was correlated to various factors.Clinical nurses should master high-risk factors thoroughly and adopt intervention measures in a timely manner.
