Objective To evaluate the role of mitochondrial permeability transition pore (mPTP) in sevoflurane-induced inhibition of apoptosis induced by oxygen-glucose deprivation and restoration (OGD/ R) in rat neurons.Methods Cortical neurons isolated from neonatal Sprague-Dawley rats born within 24 h, were cultured primarily and seeded in 6-well plates (2 ml/well) at a density of 1 × 106 cells/ml.The neurons were randomly divided into 5 groups (n =72 each) using a random number table: control group (group C), OGD/R group (group O), mPTP opener group (group A), mPTP opener + sevoflurane group (group AS) , and sevoflurane group (group Sev).The cells were cultured in normal culture medium in group C, and the cells were subjected to OGD for 90 min followed by restoration of O2-glucose supply for 24 h in the other groups.In A and AS groups, mPTP opener atractyloside 20 μmol/L was added immediately after OGD.In Sev and AS groups, the cells were post-conditioned with 2% sevoflurane for 1 h immediately after OGD.The neurons were collected at 24 h of OGD in O and A groups, or at 23 h of OGD in Sev and AS groups.Annexin V-FITC/PI double staining was performed to count apoptotic neurons, apoptotic rate was calculated, and cell survival rate was measured using MTT assay.The mitochondrial membrane potential (MMP) was measured by using JC-1 fluorescence probe as indicator.The opening of mPTP was determined through assessing the changes of mitochondrial optical density (△OD540 of mPTP).The expression of pro-apoptotic factors Bid, Bim, Puma protein and mRNA was detected by semi-quantitative reverse transcription polymerase chain reaction and Western blot.Results Compared with group C, apoptotic rate was significantly increased, cell survival rate and MMP were decreased, the opening of mPTP was increased, and the expression of Bid, Bim, Puma protein and mRNA was up-regulated in the other groups.Compared with group O, apoptotic rate was significantly decreased, cell survival rate and MMP were increased, the opening of mPTP was decreased, and the expression of Bid, Bim, Puma protein and mRNA was down-regulated in Sev group.Compared with group Sev, apoptotic rate was significantly increased,cell survival rate and MMP were decreased, the opening of mPTP was increased, and the expression of Bid, Bim, Puma protein and mRNA was up-regulated in A and As groups.Compared with group A, apoptotic rate was significantly decreased, cell survival rate and MMP were increased, the opening of mPTP was decreased, and the expression of Bid, Bim, Puma protein and mRNA was down-regulated in group AS.Conclusion Sevoflurane mitigates OGD/R-induced apoptosis in rat neurons through inhibiting mPTP opening.

Objective To investigate the error monitoring function damages on the patients with schizo?phrenia ( SCH) . Methods A total of 32 patients with schizophrenia were compared with matched 34 health con?trols ( HC) on the error monitoring tasks which were compiled by E?Prime. Results The comparison between SCH group ((713.22±174.52)ms,( 491.14±170.29) ms,( 1060.31±130.84) ms,(8.28±12.55)time,( 8.00± 7.53)time respectively) and HC group ((560.73±156.94) ms,(395.62±188.03) ms,(989.85±104.33) ms, (2.97±4.13) times,(3.12±6.50) times) on the reaction time of choice,assessment,incongruent condition,the numbers of uncertain and the numbers of dropout were significant ( t=-3.737, P=0.000;t=-2.159, P=0.035;t=-2.426, P=0.018;t=-2.282, P=0.022;t=-2.824, P=0.006) . The SCH group and HC group did not signifi?cantly difference in Full Correct((124.72±23.74)/(131.74±21.96)times),Full Error((15.69±17.64)/(13.35± 18.63)times),Part Correct((6.83±10.40)/(4.21±7.03)times),Part Error((2.91±10.91)/(0.62±1.10)times) and Accuracy((0.831±0.161)/(0.874±0.159))(P>0.05).There was no significantly correlation among the course of disease,HAMA,HAMD and the error monitoring. Conclusion These results demonstrate that the error monitoring function damages on the patient with SCH may be involved in the dysfunction of anterior cingulate cortex.

Objective: To assess the effect of coronary collateral circulation (CCC) on myocardial viabilityin patients with chronic total occlusion of left anterior descending (LAD) artery. Methods: A total of 101 consecutive patients with confirmed diagnosis of total LAD occlusion in our hospital were enrolled. Rest 99mTc-MIBISPECT myocardial perfusion and 18F-FDG PET were performed, in addition all patients received coronary angiography (CAG) at 3 months front and back. Both images were reconstructed in the same machine and QPS software was used to obtain the summed rest score (SRS), abnormal resting total perfusion defect (TPD), viable and non-viable myocardium, LVEDV, LVESV and LVEF in relevant patients. Based on CAG result, the patients were divided into 2 groups: CCC group, n=39 and No CCC group, n=62; according to existing old myocardial infarctionand location of LAD occlusion, the patients were further divided into 4 subgroups. The above parameters were compared among different groups. Results: There were 86 male and 15 female patients with the mean age at (59.92±11.43) years. Relevant parameters in CCC group and No CCC groupwere as in SRS: (21.23±9.68) vs (28.56±8.76), TPD: (30.03±13.69) %vs (40.37±12.50) %, viable myocardium: (21.77±13.12) % vs (13.66±9.23) %, non-viable myocardium (8.28±8.58) %vs (27.40±12.97) %, all P<0.05; in LVEDV: (109.82±30.01) ml vs (173.71±57.69) ml, LVESV: (62.82±22.39) ml vs (122.53±51.66) ml, LVEF: (43.85±8.46) % vs (31.03±8.30) %, all P<0.05. Conclusion: Our preliminary study found that CCC could maintain left ventricular rest perfusion, myocardial viability and protect cardiac function in patients with chronic total LAD occlusion.

Aim To investigate the curative effect of rAAV-PR39-ADM,which co-expressed the gene of an-tibacterial peptide (PR39 ) and adrenomedullin (ADM),in a rat cerebral ischemia/reperfusion (I/R) injury.Methods In vitro,Matrigel angiogenesis as-say was made with human umbilical vein endothelial cells.In vivo,the cerebral I/R model was established by the occlusion of the cerebral artery for 2h and then reperfused for 24 h.SD rats were randomly divided in-to sham group,I/R+normal saline group,I/R+null virus (AAV ) group, and IR +rAAV-PR39-ADM group.rAAV-PR39-ADM,saline and null virus were administered through the femoral vein after 24 h of the reperfusion in I/R group.MRI,neurological deficit score,TTC and HE staining were measured respective-ly 1 ,2,3 and 4 weeks after the injection in order to e-valuate the therapeutic efficacy.Results In vitro, rAAV-PR39-ADM group had significant angiogenic effect compared with sham group and null virus group. In vivo,successful I/R model was verified by the ima-ges of MRI.Compared with sham group,the nerve function defect score and the cerebral infarction size in each time nodes were significantly raised in I/R groups (P<0.01).There was no significant difference in in-farct size and nerve function defect score between I/R+normal saline group and I/R +null virus (AAV ) group,and obviously,the IR +rAAV-PR39-ADM group lowered these indexes compared with the other two groups.HE staining showed that the number of neurons,new capillaries vessels of I/R +PR39-ADM group were significantly more than those in group I/R and group I/R +null virus.Conclusion The treat-ment of rAAV-PR39-ADM promotes vascular forma-tion,neuron protection and reduces the infarct size in the model of cerebral ischemia/reperfusion.

AIM:To explore the expression and possible function of histamine H3 receptor (H3R) in striated myogenesis and the differentiated C2C12 cells.METHODS: H3R and myogenesis late marker myosin heavy chain (MHC) were detected at mRNA and protein levels during C2C12 myogenesis.H3R antagonist ciproxifan was added and the expression of the myogenesis early marker desmin, intermediate markers myogenin and MHC was detected.Differentia-ted myoblasts were loaded with Fluo-4 calcium indicator dye and the effect of R-( a)-methylhistamine ( RMeHA) on the cy-toplasmic calcium concentration was determined under the 200 mA electrical stimulation.RESULTS: The expression of H3R and MHC was increased during myogenesis.Ciproxifan incubation had no influence on the 3 striated myogenesis mar-kers (P>0.05).In C2C12 myoblasts, RMeHA (10 nmol/L~100 μmol/L) effectively diminished cytoplasmic calcium peak when the cells were electrically paced (P<0.05).The best inhibitory effect of RMeHA was observed at dose of 100 nM for 10 min and 20 min, which was higher than that for 5 min (P<0.05).CONCLUSION: H3R might have little effect on the myogenic differentiation, but diminishes cytoplasmic calcium peak of the differentiated myoblasts under electri-cal stimulation.

Objective:To investigate the clinicopathological features of gastric adenocarcinoma of fundic gland type (GA-FG).Methods:A total of 12 patients, including 7 cases treated with endoscopic submucosal dissection (ESD), were diagnosed as having GA-FG in Nanjing Drum Tower Hospital from January 2018 to August 2019. Morphological changes were analyzed by reviewing endoscopic and pathological results. Patients were followed up after definitive diagnosis.Results:The clinical symptoms of patients with GA-FG were nonspecific. No Helicobacter pylori infection was identified. The lesions were found in the non-atrophic gastric mucosa of the upper 1/3 portion in 10 cases and middle 1/3 portion in 2 cases. Endoscopically, the most common features were whitish color (9 cases), and all lesions diameter≤1 cm. Their macroscopic types were classified as 0-Ⅰ (2 cases), 0-Ⅱa (9 cases) and 0-Ⅱc (1 case) respectively. All lesions had sharp boundary, with branching dilated blood vessels on the surface. Five in 7 cases who were treated with ESD showed submucosal invasion. Immunohistochemically, 9 cases were classified as the chief cell type , 3 as the mixed type, 11 MUC6 positive, 4 MUC5AC positive, 2 MUC2 positive, and 3 CD10 positive. P53 was detected in all 12 cases, and 9 cases had low Ki-67 staining index (<10%). The mean time of follow-up was 11 months, and 11 patients survived. Conclusion:GA-FG should be taken into consideration when the polyps are found in the upper part of the stomach, with whitish color, and branch dilated blood vessels on the surface. Excellent clinical outcomes can be achieved for GA-FG patients with ESD.
