Objective To observe the clinical efficacy and safety of application of lafutidine treated in curing peptic ulcer.Methods Eighty-four patients with peptic ulcer were randomly assigned to receive either lafutidine(10 mg) twice daily in 42 patients of cured group or lansoprazole (30 mg) once daily for 4 weeks in 42 patients of control group.Ulcer healing rate and clinical performance were examined after treatment.Results The first,third and seventh day of peptic ulcer healing rate were 38.09％ (16/42), 71.42％ (30/42) and 90.47％ (38/42) in the lansoprazole group and 23.81％ (10/42), 76.19％ (32/42) and 85.71％ (36/42) in the lafutidine group.There were no siginificant difference between two groups (P =0.157,0.620, 0.736).Gastroscope examination showed the complete healing rate, average healing rate and general clinical effectiveness were 61.90％(26/42) ,30.95％(13/42) and 97.61％(41/42) in the lansoprazole group,while the number for lafutidine group were 57.14％ (24/42), 28.57％ (12/42) and 95.23％ (40/42).There were no siginificant difference between two groups (P =0.657, 0.811, 1.000).No severe side-effect was occurred in both groups.Conclusion Use Lafutidine to cure peptic ulcer can promote healing effectively, improve patients' clinical symptoms which is similar to lansoprazole.

Objective To observe the influence of short-term continuous subcutaneous insulin infusion(CSII)on ?-cell function in newly diagnosed type 2 diabetes(T2DM).Methods A total of 32 inpatients with newly diagnosed T2DM who had a 14-day course of CSII were randomly assigned to two groups of OGTT and arginine stimulating test(AST).Before and after 3 days and 14 days CSII treatments,OGTT and AST were performed respectively.The changes of the values of plasma glucose,HOMA-IR,HOMA-? and △C30/△G30,△C120/△G120 or arginine-induced acute C-peptide reaction(ACRARG)in two groups were compared.Results In OGTT,the values of plasma glucose and HOMA-IR were decreased,HOMA-? and △C120/△G120 were increased significantly after CSII therapy,both in day 3 and day 14;and △C30/△G30 were unchanged after 3 days but increased markedly after 14 days.However,in ACRARG,the above mentioned parameters almost remained unchanged after CSII treatment in 3 days or 14 days.Conclusions In newly diagnosed T2DM with elevated fasting glucose levels,intensive insulin therapy can partly improve ?-cell function showed by OGTT,not by AST.

OBJECTIVE:To investigate the protective effect of the compatibilities of ginsenosides Rg1 and aconitine on myocar-dial cell of in vitro cultured heart failure model. METHODS:The myocardial cells of neonate rat were grouped into normal control group,model group,positive control group(Deslanoside injection,1×10-7 mol/L),ginsenosides Rg1 group(1×10-8 mol/L),acon-itine group (1 × 10-9 mol/L) or their compatibilities groups (1∶1,2∶1,1∶2,V/V). Except for normal control group,other groups were given 0.8%pentobarbital sodium to induce heart failure model of myocardial cells. After modeling,each group was given rele-vant medicine for 1 h,and then the activities of T-ATPase,Ca2+-Mg2+-ATPase,Na+-K+-ATPase in cells were all detected. The activi-ties of acyl carrier protein(ACP)and lactate dehydrogenase(LDH),and the contents of brain natriuretic party(BNP),TNF-α and total glycogen were measured in cell culture fluid. RESULTS:Compared with normal control group, T-ATPase and Ca2+-Mg2+-ATPase activities were decreased significantly in model group;meanwhile,Na+-K+-ATPase activity was increased signifi-cantly,and ACP,LDH activities and BNP content in cell culture fluid were increased significantly(P<0.05). Compared with mod-el group,the activities of T-ATPase in treatment groups were increased significantly,while the activity of LDH in cell culture fluid was decreased significantly;when the volume ratio of ginsenoside Rg1 to aconitine was 2∶1,protective effect was the strongest;the activities of Na+-K+-ATPase in aconitine group and compatibility groups were all decreased significantly,with statistical signifi-cance(P<0.05). The activities of ACP and BNP in cell culture fluid were all decreased in treatment groups,but the content of to-tal glycogen in cells and the TNF-α content of in cell culture fluid had no change (P>0.05). CONCLUSIONS:Compatibility of ginsenosides Rg1 and aconitine can improve ATPase activities and membranous permeability,regulate BNP secretion and protect myocardial cell of heart failure model,especially the compatibility of ginsenosides Rg1 to aconitine of 2∶1 ratio.

Objective To observe the role of the health education model in pain self- efficacy for patients with cancer pain. Methods Sixty- four patients suffering from cancer pain were enrolled into the study and self- contrast experiment was made on each patient. The health education model was set up and health education for each patient with cancer pain was implemented. The pain, self- efficacy, cancer pain knowledge before and after the intervention were observed by Numerical Rating Scale (NRS),Chronic Pain Self- efficacy Scale(CPSS) and Cancer Pain Knowledge Questionnaire. Results NRS score were (5.38 ±0.19) points and (1.05 ± 0.11) points before and after the intervention, and there was significant difference (t =25.288, P = 0.000). Before intervention, pain management self- efficacy, physical function self- efficacy, symptom coping self- efficacy of CPSS scores were (10.38 ±0.37) , (20.97±0.81) , (16.86 ± 0.49) points, while after the intervention, the scores were (19.31± 0.30) , (33.25 ± 0.60) , (29.75 ±0.51) points, there were significant differences ( t = -33.225, -18.236, -18.235, all P = 0.000). Before and after the intervention, the answer rate of Cancer Pain Knowledge Questionnaire was 50.00%(32/64) and 87.50%(56/64), there was significant difference( χ2=20.51, P < 0.01). Conclusions To set up the health education model and implement health education for each patient with cancer pain can improve the patient′s pain management and enhance self-efficacy.

Objective To compare the MRI features of hepatic neuroendocrine tumors (NET G1,G2) and neuroendocrine carcinomas (NEC G3),as well as to improve the accuracy in hierarchical diagnosis.Methods Twenty patients with histopathologically proven NET and nineteen patients with histopathologically proven NEC were retrospectively analyzed.The morphological and MR signal features were compared.Results The morphological features of vascular invasion (P ＜ 0.05) and lymphadenectasis or necrosis (P ＜ 0.05),as well as the MR signal features on portal phase (P ＜ 0.05) and delayed phase (P ＜0.05) were different between the NET group and the NEC group;contrast to noise ratios (CNR) were also different between the two groups (x2 =5.14,P ＜ 0.05),CNR of the NEC group on both arterial phase (Z =121.75,P ＜ 0.05) and portal phase (Z =139.31,P ＜ 0.05) were significantly lower than the NET group;ROC analysis of CNR demonstrated an area under the curve of 0.729 (P ＜ 0.05) on portal phase,when the optimal cut-off value of-61.38 was used,a sensitivity of 90.0％ and a specificity of 63.2％ can be achieved.Conclusions MRI plays an important role in the hierarchical diagnosis of hepatic neuroendocrine neoplasms.The signs of vascular invasion,lymphadenectasis or necrosis as well as the MR signal features during dynamic enhanced scanning are of great value in differentiating NETs from NECs.

Objective To evaluate expression of HDAC2 in peripheral blood mononuclear cells(PBMCs)from glucocorticoid-resistant versus glucocorticoid-sensitive patients with sudden sensorineural hearing loss and identi-ty the relationship between the level of HDAC2 and glucocorticoid insensitivity.Methods PBMCs were collected from10 patients with deviation of nasal septum (control group)and 20 sudden sensorineural hearing loss patients be-fore and after intratympanic methylprednisolone for 10 days.We divided the SSNHL patients into 2 groups (GC sensitive group and GC insensitive group)according to their hearing recovery.Real time PCR and HDAC2 Assay Kit were used to detect the expression level of HDAC2 mRNA and HDAC2 activity in PBMCs.The data were analyzed with SPSS 17.0 software.ResuIts Before intratympanic methylprednisolone,the level of HDAC2 activity were sig-nificantly depressed in SSNHL patients,while the HDAC2 mRNA expressing much higher than the control group. The expression level of HDAC2 mRNA increased significantly after intratympanic methylprednisolone.The HDAC2 activity in GC sensitive group increased significantly.ConcIusion Knockdown of HDAC2 expression induces corti-costeroid in-sensitivity.Glucocorticoids can increase the expression of HDAC2 mRNA.HDAC2 activity can be down-regulated by post-translational modifications.

BACKGROUND: Previous studies demonstrated that eucommia bark can promote bone marrow stern cells (BMSCs) differentiated into osteoblasts, but relative mechanism is poorly understood. OBJECTIVE: To investigate the effects of eucommia bark water/methanol extracts on expressions of osteopontin (OPN) and osteoprotegedn (OPG) in rat BMSCs. METHODS: Totally 2 g eucommia bark powder were added into water or methanol to 16 mL and oscillated for 1 hour at room temperature. After soaked overnight, both extracts were centrifuged at 15 000 r/min for 10 minutes. Water extract was obtained from supernatant in water soaked powder. In methanol soaked powder, methanol extracts was obtained by concentrated supernatant in vacuo and resolved using 16 mL water. Water and methanol extracts were then filtered by 0.22 μm membrane, and conserved at -20℃. Six SD rats, aged 2 months, were selected, and the 3~(rd)passage of BMSCs were induced by water or methanol extracts with dilution of 1 × 10~(-2), 1 × 10~(-3), 1 × 10~(-4) and 1 × 10~(-5), respectively. PBS was added in the negative control group. All cells were cultured for 6 days. Expressions of OPN and OPG was measured by immunocytochemistry at 6 days with induction. The expression of OPN and OPG induced by water and methanol at 1 ×10~(-3) and 1×10~(-4) dilution was detected by RT-PCR. RESULTS AND CONCLUSION: Immunocytochemistrical results indicated that both water and methanol extracts of eucommia bark simulated OPN and OPG expression, in particular with dilution of 1×10~(-4). The methanol extracts had a stronger effect than water extract, but the expression of OPG did not change obviously. RT-PCR demonstrated that at the 3rd day of inducement, the level of OPN expression induced by water extract was higher than that of methanol extract, and no OPG expression was detected. Osteogenic differentiation of rat MSCs induced by eucommia bark water/methanol extracts relates to stimulating expression of OPN, which has no correlation to OPG. OPN expression induced by water extract is early than that of methanol extract.
