Objective The molecular basis for opiate tolerance and dependence remains poorly understood despite extensive investigation in several preparations, including the hippocampus. Recent studies have implicated that the hippocampus played a central role in opiate tolerance, dependence and withdrawal. The current study is to explore the change in guanine nucleotide binding protein-inhabitant (Gi_2) protein in primary cultured hippocampal neurons with morphine treament. Methods The hippocampus was harvested from newborn Sprague-Dawley rats. Primary hippocampal neuronal cultures of 7 days in vitro were used and divided randomly into six groups (n=6), i.e. morphine treatment 4h group (M4), 8h group (M8), 16h group (M16), 24h group (M24), 48h group (M48) and control group (C). All morphine treatment groups were treated with morphine (10?mol/L). C group was treated with saline. The G protein levels were determined with immunofluorscence and laser scanning confocal microscope (LSCM) imaging techniques. Results Gi_2 protein levels in M16, M24 and M48 groups decreased significantly compared with that in C group (P0.05). Among M16, M24 and M48 groups, Gi_2 protein level was lowest in the M48 group. Conclusion The results indicated that Gi_2 protein levels decreased significantly in primary cultured hippocampal neurons with morphine treatment, which might be a potential molecular mechanism of opioid tolerance and dependence.

Objective To investigate the changes in inhibitory guanine nucleotide binding protein Gi_2 in five brain regions of morphine addicted rats: ventral tegmental area, nucleus accumbens, prefrontal cortex, hippocampus and locus caeruleus. Methods 36 adult male SD rats were randomly divided into six groups (n=6): acute morphine dependent group, acute abstinence group, acute control group, chronic morphine dependent group, chronic abstinent group and chronic control group. Morphine dependent models were reproduced. Withdrawal syndrome was induced with naloxone 5mg/kg for 30min in rats of abstinence group. All rats were sacrificed by decapitation. Frozen sections of coronal plane of respective brain regions (ventral tegmental area, nucleus accumbens, prefrontal cortex, locus coeruleus, hippocampus) were prepared. The relative concentrations of Gi_2 protein were determined with immunohistochemical methods. Results Gi_2 proteins in acute morphine dependent group and acute abstinence group were significantly decreased compared with that of acute control group in nucleus accumbens (P

Objective To evaluate prognostic value of N-terminal B-type brain natriuretic peptide (NT-proBNP) combined with galectin 3 of prognostic value in patients with chronic heart failure (CHF).Methods Determination of 92 cases of CHF patients on admission and at discharge plasma NT-proBNP and galectin-3 levels,then after the patients discharge we follow up 16 months and observe the internal recurrent heart failure hospitalization rate and mortality.Results In patients the heart function of New York Heart Association (NYHA) Ⅰ,Ⅱ,Ⅲ,Ⅳ level,NT-proBNP were (351.6 ± 467.5) pg/ml,(493.2 ± 411.7) pg/ml,(1 289.6 ± 737.8) pg/ml,(2 719.2 ± 1 044.1) pg/ml,galectin-3 (12.23 ± 6.12) ng/ml,(13.59± 5.46) ng/ml,(19.18 ± 7.44) ng/ml,(26.61 ± 8.82) ng/ml as well.NT-proBNP and galectin-3 levels were increased with the depression of cardiac function.The patients who had higher NT-proBNP or galectin3 levels discharged and occurred the more probability of re-hospitalization on account of heart failure or death.Compared to those patients with one of them increased,the patients whose discharge NT-proBNP and galectin-3 value were both increased with significantly poor outcome.Conclusions Both NT-proBNP and galectin-3 were independent predictors of poor prognosis in patients with heart failure.Galectin-3 combined with NT-proBNP can assess the prognosis of patients with CHF more effectively.

Objective To investigate the relationship among carotid atherosclerosis,plasma homocysteine and D-dimer level in patients with acute cerebral infarction.Methods Two hundred and eightyseven cases of patients with acute cerebral infarction treated in Pudong Hospital,Shanghai from January 2011 to March 2012 were enrolled into the observation group and 287 cases of healthy people not suffering from cerebral infarction or other patients had nothing to do with cerebrovascular disease were selected into the control group.The serum levels of plasma homocysteine were determined by fluorescence polarization immunoassay (FPIA) and D-dimer level by double antibody clip method.At the same time,neck vascular artery ultrasound were performed by MycoCardR Reader Ⅱ.The relationship of carotid atherosclerosis with plasma homocysteine and D-dimer were compared between these two groups.Results There were significant differences on total cholesterol ((4.25 ± 0.92) mmol/L vs (4.98 ± 0.88) mmol/L,t =3.244,P ＜ 0.05),triacylglycerol ((1.48 ±0.82) mmol/L vs (1.78 ± 1.09) mmol/L,t =3.564,P ＜ 0.05),low density lipoprotein ((2.52-0.76) mmol/L vs (2.92 ± 0.73) mmol/L,t =2.987,P ＜ 0.05),high-density lipoprotein ((1.38 ± 0.26) mmol/L vs (1.06± 0.29) mmol/L,t =3.964,P ＜ 0.05),systolic pressure ((130.28 ± 14.78) mm Hg vs (152.98 ± 20.45) mm Hg,t =3.264,P ＜ 0.05),diastolic pressure ((78.45 ± 16.02) mm Hg vs (93.81 ± 16.88) mm Hg,t =2.785,P ＜0.05) and common carotid artery IMT(left:(0.86 ±0.41)mm vs (1.18 ±0.25)mm,t =2.164,P ＜0.05;right:(0.87 ± 0.39)mm vs (1.12 ± 0.29)mm,t =2.254,P ＜ 0.05) between observation group and control group.Homocysteine concentration and the D-dimer level of patients with carotid atherosclerosis were significant higher than that without carotid atherosclerosis (homocysteine concentration:(12.89 ± 6.56) μnol/L vs (3.17 ± 0.12) μnol/L,t =2.324,P ＜ 0.05 ; D-dimer level:(1.53 ± 0.59) mg/L vs (0.33 ± 0.23) mg/L,t =2.753,P ＜ 0.05).Conclusion The plasma homocysteine concentration and the D-dimer levels are correlated with carotid atherosclerosis in patients with acute cerebral infarction.

Objective To discuss the influence of psychological nursing on the therapeutic effect of patients with newly diagnosed type 2 diabetes. Methods Patients (60 cases) who received psychological nursing were set as the nursing group. Patients (65 cases) who did not received psychological nursing were set as the control group. The number of patients who received early insulin treatment and whose fasting plasma glucose return to normal value on the 7th and 30th days after treatment was observed. Results The number of patients who received early insulin treatment and whose fasting plasma glucose return to normal value on the 7th and 30th days after treatment in the nursing group was higher than that of the control group (P<0.01). Conclusions Psychological nursing of patients with newly diagnosed type 2 diabetes could make patients obey doctors' advice and accept early insulin treatment to control plasma glucose and delete the toxicity of high concentration of plasma glucose as soon as possible.

Aim To assess the effects of N -[2-p-bromo-cinnamylamino-ethyl]-5-isoquinoline-sulfonamide (H-89), a potentially selective inhibitor of Protein Kinase A (PKA), on cardiac membrane ion channels and transporters, which will further fulfill our understanding of pharmacology of PKA inhibitors.Methods Whole-cell patch clamp was used to investigate the effects of H-89 on cardiac L-type Ca~(2+) current (I_(Ca-L)), Na~+ current (I_(Na)), inward rectifier K~+ current (I_(K1)), transient outward K~+ current (I_(to)) and Na~+-Ca~2+ exchanger current (I_(Na/Ca)) in enzymatic dissociated SD rat ventricular myocytes.Results H-89 at 1～10 μmol·L~(-1) could inhibit I_(Ca-L) , I_(Na) , and Ito in a concentration-relative manner (P <0.05). At low concentra-tion (5 μmol·L~(-1)), H-89 completely inhibited I_(K1) (P <0.05) just as the action of 0.5 mmol·L~(-1) BaCl_2.Further, H-89 at 1～10 μmol·L~(-1) had no significant effect on I_(Na/Ca) (P >0.05).Conclusion The direct or PKA-mediated indirect action maybe involved in the effects of H-89 on ion currents and transporter.

Objective To explore the coincidence rates of positive and reverse blood group of infants younger than six months in Xiamen area in recent years,and to analyze the difference of anti-A or anti-B antibody in infants of different age groups and different ABO blood groups.Methods 2 993 hospitalized infants from 0 to 6 months in five hospitals of Xiamen area were selected.EDTA-K2 anticoagulant blood samples were collected.Micro-column gel agglutination assay was used in ABO blood group.All the infants were divided into six groups,which aged from 0-7 days,8-14 days,15-31 days,1-2 months,3-4 months and 5-6 months.The coincidence rates of positive and reverse blood group of each group were compared.Results Of the 2 993 infants,303 cases were AB type.The coincidence rates of positive and reverse blood group of the other infants which aged from 0-7 days,8-14 days,15-31 days,1-2 months,3-4 months and 5-6 months were 57.0%,61.0%,63.0%,71.8%,84.9% and 91.0%,respectively.The coincidence rates of positive and reverse blood group between different blood groups had no statistically significant difference(x2=0.842,P=0.657).The coincidence rates of positive and reverse blood group had statistically significant difference among different age groups(x2=185.683,P<0.05).Conclusion The IgM antibody of ABO blood group is detected in infants younger than six months.Positive and reverse blood group is necessary in ABO blood group identification of infants to guarantee the safety clinical blood transfusion.

OBJECTIVE To explore the predictive value of human telomerase RNA gene component(hTERC) gene amplification and high-risk human papilomavirus(HR-HPV) testing in cervical intraepithelial neoplasia(CIN) as a marker for early diagnosis of cervix carcinoma.METHODS Fluorescence in situ hybridization(FISH) was used to detect the amplification of hTERC of cervical epithelial cells in 72 cases.By using hybrid capture 2(HC-2),two types of the HR-HPV DNA(HPV16/18) of each case were detected.Then,the results were compared with the pathologic diagnosis.The dual-color probe we used was GLP TERC/CSP 3.HeLa cells and lymphocytes from normal marrow were the positive control,while the cervical specimens from healthy outpatients were the negative control.RESULTS hTERC Gene amplification of specimens was tested in 72 cases,the positive amplification rate of hTERC gene in the cervicitis/CINⅠgroup and normal,compared to the cervical carcinomas(100%) and CIN Ⅱ/Ⅲ(68.75%),which showed a significant difference.The rates in CINⅡ and CINⅢ were 60.00% and 83.33%,respectively,which showed a significant difference compared with normal and CINⅠ/inflammation groups.hTERC gene amplification was positive in both HeLa cells and lymphocytes from normal marrow and HC-2 testing was positive in 32 cases of patients containing 11 cases of CINⅡ/Ⅲ,3 cases of cervical cancer,18 cases of cervicitis/CIN1 diagnosed.The positive predictive value(PPV) and specificity(Sp) of hTERC for the high-grade CIN was significantly higher than the PPV and Sp of HC-2 HR-HPV testing.CONCLUSIONS hTERC Gene involves in the progression and occurrence of cervical intraepithelial neoplasia and cervical squamous carcinoma.As a marker for early diagnosis of cervical intraepithelial neoplasia and cervical squamous carcinoma,the FISH method for hTERC gene is more reliable to differentiate the malignant diseases from the benign ones in cervixes than HC-2 HR-HPV DNA testing.The combined detection of HR-HPV and hTERC gene will provide more effective and suitable management to enhance the early diagnosis rate of cervical intraepithelial neoplasia and cervical squamous carcinoma.
