r cirrhosis. NO and ET-1 are involved corporately in the development of liver cirrhosis, but not the main factors facilitating hypoxemia of liver cirrhosis.

Objective To investigate the psychological characteristics of the patients with functional dyspep-sia(FD). Methods The Zung serf-rating anxiety scale(SAS) and the Zung serf-rating depression scale(SDS) were employed to evaluate the anxiety mood and depression mood respectively of 110 FD patients ( group A) and 100 healthy volunteers (group B). The incidences of anxiety and depression in patients < 60 years and patients ≥60 years in group A were determined respectively. Results The anxiety ( 50.2±10.5 ) and depression scores ( 51.8±10.8)of group A were higher than group B [ (33.6±5.7) , ( 42.9±9.6) ] with a significant difference ( P<0.01 ). In group A, the anxiety incidence(66.0% ) in patients < 60 years was higher than patients ≥ 60 years (38.3%) ,while the de-pression incidence in patients ≥60 years(61.7% ) was higher than patients <60 years(42.0% ) ,both with signifi-cant differences ( all P<0.05 ). Conclusion FD patients show the psychological characteristics of anxiety and de-pression, and the characteristics type may vary in different age groups.

Background Electroacupuncture pretreatment plays a protective role in myocardial ischemia/reperfusion (I/R) injury and microRNAs (miRNAs) could act on various facets of cardiac function. However, the role of miRNAs in the cardioprotection by electroacupuncture pre-treatment on myocardial I/R injury remains unknown. The purpose of the study was to examine whether miR-214 was involved in cardio-protection by electroacupuncture. Methods Using rat myocardial I/R model, we examined the role of electroacupuncture pretreatment in myocardial I/R injury and analyzed the changes in the expression of miR-214. In addition, I/R was simulated in vitro by performing oxy-gen-glucose deprivation (OGD) on H9c2 cell cultures, and the effect of electroacupuncture pretreatment on I/R injury as well as expressional level of miR-214 were examined in vitro. Furthermore, the miR-214 mimic was transfected into OGD-treated H9c2 cells, we analyzed the cell apoptosis, lactate dehydrogenase (LDH) and creatine kinase (CK) activities, intracellular free Ca2+concentration ([Ca2+]i) as well as the relative protein levels of sodium/calcium exchanger 1(NCX1), BCL2-like 11 (BIM), calmodulin-dependent protein kinase IIδ(CaMKIIδ) and Cyclophilin D (CypD). Results The in vivo results revealed that compared with the I/R group, the electroacupuncture pretreatment group showed significant decreased myocardial infarct size, as well as the increased indices of the cardiac function, including heart rate, mean arterial pressure, left ventricular systolic pressure and maximal rate for left ventricular pressure rising and declining (±dp/dt max). In addition, electroacupuncture pretreatment could inhibit the elevation of LDH and CK activities induced by I/R injury. The quantitative PCR (qPCR) results demonstrated electroacupuncture pretreatment could provide cardioprotection against myocardial I/R injury in rats with miR-214 up-regulation. In the meanwhile, in vitro, electroacupuncture pretreatment protected H9c2 cells from OGD-induced injury. Trans-fection of miR-214 mimic showed protective effects on OGD-induced injury to H9c2 cells by reducing apoptosis, decreasing LDH and CK activities, rescuing the OGD-induced Ca2+and down-regulating elevated protein levels of NCX1, BIM, CaMKIIδand CypD. Conclusions Our findings firstly demonstrated that electroacupuncture pretreatment promotes the expression of miR-214 in myocardial I/R injury and miR-214 contributes to the protective effect of electroacupuncture on myocardial I/R injury.

Objective To evaluate the effect of captopril and isoflurane preconditioning on cell apoptosis during myocardial ischemia/reperfusion (I/R) in rabbits.Methods Forty New Zealand white rabbits of both sexes,weighing 1.8-2.5 kg,were randomly divided into 5 groups (n =8 each) using a random number table:sham operation group (group S),group I/R,isoflurane preconditioning group (group I),captopril preconditioning group (group C) and captopril and isoflurane preconditioning group (group C + I).The animals were anesthetized with 3％ pentobarbital sodium 30 mg/kg.Myocardial ischemia was induced by occlusion of the left anterior descending branch of coronary artery for 30 min followed by 120 min of reperfusion.1.1％ isoflurane was inhaled for 30 min followed by 15 min washout before myocardial ischemia in group I.Captopril 25 mg/kg was given through a gastric tube into the stomach at 24 h before myocardial ischemia in group C.Captopril 25 mg/kg was given through a gastric tube into the stomach,24 h later 1.1％ isoflurane was inhaled for 30 min followed by 15 min washout,and then myocardial ischemia was performed in group C + I.The rabbits were sacrificed at the end of reperfusion and myocardial specimens were removed for microscopic examination and observation of ultrastructure,and for determination of the expression of Bcl-2 and Bax proteins (by Western blot).The apoptosis rate was detected by flow cytometry.Bcl-2/Bax ratio was calculated.Results Compared with group S,the apoptosis rate was significantly increased,the expression of Bcl-2 and Bax proteins was up-regulated,and Bel-2/Bax ratio was decreased in I/R,I,C and C + I groups (P ＜ 0.05).Compared with I/R,I and C groups,the apoptosis rate was significantly decreased,Bcl-2 protein expression was up-regulated,Bax protein expression was down-regulated,and Bcl-2/Bax ratio was increased (P ＜ 0.05),and the pathological changes were significantly attenuated in group C + I.Conclusion Regulation of Bcl-2/Bax ratio and inhibition of apoptosis in myocardial cells are involved in the mechanism by which isoflurane and captopril preconditioning reduces I/R injury in rabbits.

Objective To detect the levels of plasma N-terminal pro-brain natriuretic peptide (NT-proBNP) and investigate its relationship with liver function, ascites and heart structure in patients with liver cirrhosis. Methods The levels of plasma NT-proBNP and various clinical and biochemical parameters were determined in 60 patients with liver cirrhosis and 30 healthy controls. Meanwhile Child-Pugh liver function was classified. All people underwent color Doppler echocardiography. Results The level of plasma NT-proBNP was significantly elevated in patients with liver cirrhosis [(38.63±36.05)pmol/L], compared with that of the controls [(7.50±8.25)pmol/L],P<0.01. There was no significant difference in different Child-Pugh class and aseites amount of liver cirrhosis. E/A < 1 and E wave decelerate time (EDT) was in-creased in liver cirrhosis. Conclusion The levels of plasma NT-proBNP in liver cirrhosis are significantly elevated, and related to early impairment of diastolic function. But it does not correlate with liver function and aseites.

OBJECTIVE: To discuss the potential problems caused by the exfoliation of the tunic albuginea after the low-temperature plasma operation. METHOD: To observe the occurrence of the tunic albuginea, exfolliating time, wound healing and its complications by following the patients received the low-temperature plasma operation from November in 2012 through June in 2013 (including 116 cases of tonsillectomy, 98 cases of adenoidectomy, 255 cases of the ablation of the inferior turbinate,8 cases of the ablation of the cyst of epiglottis, and 4 cases of the ablation of the tumor of larynx) together with reviewing the relevant literatures. RESULT: The tunic albuginea exfolliated about two weeks after tonsillectomy, bleeding was found in 3 cases, one of which was related with inappropriate eating; the exfoliation about two or three weeks after adenoidectomy, without the occurrence of the narrow nostril and pharyngeal cavity adhesion; about four weeks after the ablation of the cyst of epiglottis, bleeding was found in 1 case; about three or four weeks after the ablation of the inferior turbinate, massive bleeding was found in one case after two months; and the ablation of the tumor of larynx, one with severe atypical hyperplasia and carcinoma in situ, the theunic albuginea did not completely exfoliate four moths after the surgery and new creatures could be found, the wound looked smooth and healed well nine moths after the surgery. The full exfoliation occur four months after the surgery for one with the neurilemmoma in the left laryngeal ventricle and the new creatures could also be found. It exfoliated eighth days after the surgry for one patient with left subglottic epitheliaoid heman-gio endothelioma and it did not recur even six months after the surgery. Another one with the cyst of the left plica aryepiglottica failed to be followed. The first three patients did not suffer from such complications as bleeding, endogenous in trachea, etc. CONCLUSION Low-temperature plasma surgery has obvious advantages, but the potential problems caused by the surgery need to be taken in accounted, especially the exfoliating time of the tunia albuginea is different after the ablation of the tumor of larynx, which is inconsistent with what the literatures reported, it could partially due to the action time of low-temperature plasma surgery with surrounding tissues.

ObjectiveTo explore the best treatment method for patients with pancreatic cancer by analyzing the clinical and survival features.MethodsThe clinical data of 74 patients with pancreatic cancer diagnosed by pathology diagnosis(surgical pathology or biopsy) or clinical diagnosis(imaging + tumor marker CA19-9) were collected.The cases were divided into 5 groups according to different therapy methods:surgery alone group(11 cases),postoperative chemotherapy group(20 cases),palliative chemotherapy group ( 13 cases),palliative radiotherapy group ( 13 cases),untreated group ( 17 cases).The clinical features and overall survival time of patients with pancreatic cancer were analyzed.ResultsThe median overall survival time of postoperative chemotherapy group was longer than that of untreated group (300 d vs.119 d,P ＜ 0.01 ) ; The median overall survival time of surgery alone group,palliative chemotherapy and palliative radiotherapy group had no significant difference compared with that of untreated group (120,164,109 d vs.119 d,P＞ 0.05 ).The patients with advanced pancreatic cancer often suffered from abdominal pain,jaundice,nausea,vomiting,weight loss and other associated symptoms.The incidence of jaundice of patients undergoing surgery was lower compared with non-surgical patients,but the difference was not significant [ 19.35％ (6/31 ) vs.37.21％ (16/43),X2 =2.75,P =0.10 ].The incidence of abdominal pain of patients with radiotherapy was lower than that of non-radiotherapy patients[ 23.08％ (3/13) vs.68.85％(42/61 ),x2 =12.59,P =0.00 ].The ascites incidence rate was 75.68％ (56/74) which shortened the overall survival time,and untreated group had the highest risk rate of ascites.ConclusionsOperation combined with chemotherapy is a better treatment that can improve the overall survival time of patients with pancreatic cancer.Radiotherapy can obviously relieve the abdominal pain.Ascites is a signal of poor prognosis during the treatment process.

Objective To investigate the relationship between the pathophysiology of Helicobacter pylori induced antral gastritis and the expression of human β -defensin (HBD) -2 in peptic ulcer before and after Helicobacter pylori eradication.Methods Patients in peptic ulcer with Helicobacter pylori-posilive (23 cases) or Helicobacter pylori-negative (20 cases) were included.And 30 normal individuals were as controls.Biopsied gastric mucosa specimens from Helicobacter pylori-positive or Helicobacter pylori-negative individuals were done and normal controls were used.The specimens were examined for pathophysiology diagnosis and HBD-2 expression by immunohistochemistry before and after Helicobacter pylori eradication.Results Helicobacter pylori infection was correlated with the histological severities of both inflammation activity and atrophy in antral gastritis (r =0.574,0.640,P ＜ 0.01 ).The expression of HBD-2 was positively correlated with Helicobacter pylori infection in all the specimens (r =0.533,0.577,P ＜ 0.01 ).Immunohistochemistry using anti-HBD-2 antiserum revealed that HBD-2 expression and inflammation activity had significantly decreased in gastric specimens obtained after Helicobacter pylori eradication(P ＜ 0.01 ).The expression of HBD-2 had no variance in the case failing in Helicobacter pylori eradication (P ＞0.05).Conclusions Helicobacter pylori infection induces HBD-2 expression in the human gastric epithelium.HBD-2 inhibits the growth of Helicobacter pylori in vitro,which suggests that HBD-2 plays an antibacterial or inhibition role in Helicobacter pylori induced gastritis.In other words,the absence of HBD-2 should enhance the histological inflammation of Helicobacter pylori induced antral gastritis.
