Aim To study the characteristics of KCNQ2/3 potassium channel expressed in CHO cells and its modulation by M_1 receptor.Methods KCNQ2 and KCNQ3 potassium channels and M_1 receptor were co-expressed in CHO cells.Whole cell patch-clamp techniques was used to observe the characteristics of KCNQ2/3 current,its modulation by the M_1 receptor,and the effects of the common potassium channel blockers.Results KCNQ2/3 current recorded in CHO cells was a slow-activation low-threshold non-inactivating,voltage-dependent outward potassium current.KCNQ2/3 current was elicited at about-60 mV,V_(1/2)(-26.8?1.2) mV and the deactivation current fitted two exponential function,with ?_(fast) of 101ms and ?_(slow) of 309 ms.The channel was not sensitive to common pharmacological blockers such as 4-AP,Ba~(2+) and TEA,but was inhibited significantly by linopirdine,with a IC_(50) of(6.5?0.83) ?mol?L~(-1).Acetylcholine suppressed the KCNQ2/3 current reversibly via M_1 receptor,with a IC_(50) of(0.7?0.05) ?mol?L~(-1).Conclusion KCNQ2 and KCNQ3 channels are the molecular basis of M-current observed in neuronal cells.KCNQ2/Q3 current expressed in CHO cells has similar characteristics as that seen in neuronal M-current.Linopirdine is a powerful blocker of KCNQ2/3 channel and acetylcholine inhibits the current by muscarinic M_1 receptor.This experiment has laid a solid basis for further study of M-current and KCNQ2/3 current,and is important for the study of neurological diseases relating to alteration of M-current,such as convulsion,epilepsy and Alzheimers disease.

Medial pancreatectomy has been gradually used in the treatment of benign tumors in neck and body of pancreas since less removal of the pancreas and the retainment of the duodenum,spleen and functional pancreas,it is less harmful to the endocrine and exocrine function of the patients.Seventeen patients received medial pancreatectomy for benign tumors in neck and body of the pancreas in the China-Japan Union Hospital of Jilin University from November 2005 to December 2010.Fifteen patients received the closure of broken ends of pancreatic head,pancreaticojejunostomy,and the other 2 received pancreaticojejunostomy.No perioperative death was found.All the patients were followed up for 2 to 45 months,and no death was recorded.No patient got new-onset diabetes and pancreatic pseudocyst,and their tumors were not relapsed.Now the retrospective analysis was carried out to this group of patients and to further regulate the surgical operation of the medial pancreatectomy.

Aim To study the involvements of nuclear factor of activated T-cells (NFATc) and NFκB in calcineurin-mediated ischemic brain damage in vivo. Methods The rat transient forebrain ischemia conducted through 15 min ischemia followed by 8, 24, and 72 h reperfusion was induced using the fourvessel method. The rats were divided randomly into five groups; sham control group, ischemia/reperfusion (I/R) group, CsA treated groups (for 8, 24, and 72 h reperfusion). Western blotting was performed to detect changes of FasL, NFATc, I-κB-α, and phospho-I-κB-α protein expression, and gel shift assays for NFAT FasL-DNA binding activities. Results Western blotting showed that the expressions of both FasL and NFATc protein were significantly increased in the hippocanpus of rat subjected to transient forebrain ischemia in comparison with those of the sham control group, which were markedly reduced by CsA. The I-κB-α protein showed no changes in all groups, and phospho-I-κB-α protein was not observed in this study. Proximal and distal FasL promoter NFAT sites bind NFAT proteins from the hippocampal neurons subjected to transient forebrain ischemia, and DNA-binding activities increased significantly compared with those of the sham control group. CsA markedly inhibited these changes. Conclusion NFATc may be involved in calcineurin-mediated ischemic brain damage and transcription factor NF-κB may not be involved.

Aim To explore the relations between anti-apoptotic role of dipfluzine (DIP) and the death signaling transduction pathway initiated by CD95 molecules, and the transcription factor involved in the transcription regulation of CD95 molecules in the hippocampal CA1 region after transient forebrain ischemia. Methods The rat forebrain transient ischemia model was established through 15 min ischemia followed by 3 days reperfusion by using the four-vessel method. The rats were divided randomly into five groups: sham control group, ischemia / reperfusion (I/R) group, DIP treated groups (20, 40 and 80 mg·kg-1 body weight, ig, separately). Western blotting and RT-PCR were performed to detect the expression changes of Fas, FasL, caspase 10 p20, caspase 8, I-κB-α, and p-I-κB-α molecules in protein and mRNA levels, separately, and immunohistochemistry for molecular localization of Fas and FasL in rat hippocampus. Results The expression of Fas, FasL, and caspase 10 p20 in protein and mRNA levels increased after I/R, which was inhibited significantly after treatment with 20 and 40 mg·kg-1 of DIP (P<0.01). In 80 mg·kg-1 of DIP group, the expression of Fas and FasL protein was not significantly different from that of I/R group (P>0.05). The expression of caspase 8 and I-κB-α showed no significant differences in all groups (P>0.05), and no gene expression was observed for p-I-κB-α protein in the study. DIP significantly affected molecular distribution of Fas and FasL protein in CA1 subregion of hippocampus. Conclusion DIP inhibits the death signaling transduction pathway initiated by CD95 molecules in rat hippocampal CA1 subregion, and NF-κB transcription factor may not be involved in the transcription regulation of CD95 molecules after transient forebrain ischemia.

Objective To explore the value of diffusion tensor tractography (DTT)in grading gliomas.Methods 27 patients with brain glioma(gradeⅠ-Ⅱ in 1 1 cases and grade Ⅲ-Ⅳ in 1 6 cases)confirmed by pathology were collected.Conventional MR and DTT were carried out and the bilateral corticospinal tracts(CST)were reconstructed before operation.The fiber density index (FDi)and relative FDi (rFDi= ipsilateral FDi/contralateral FDi)of CST was measured.Results The FDi of ipsilateral CST was lower than that of the contralateral CST in all patients(P <0.05).The bilateral FDi had no statistical difference in low-grade glioma (LGG)and high-grade glioma (HGG)(P >0.05).The rFDi of LGG was higher than that of HGG (P <0.05).Conclusion In com-bination with conventional MR,DTT can improve the accuracy of grading gliomas.

Objective To assess the association between helicobacter pylori (HP) infection and dyslipidemia in different gender population.Methods We conducted cross-sectional analysis using data of 1921 cases of demographic characteristics,anthropometry,life style,lipid profile,etc.,from the subjects who received health examination from January 2010 to June 2012 in Department of Geriatrics,Tongji Hospital.Diagnosis of HP infection was achieved by using 14C-Urea Breath Test (14C-UBT).The participants were divided into HP infection positive group and HP infection negative group by 14C-UBT.Results In female subjects,the levels of total cholesterol/high-density lipoprotein cholesterol (TC/HDL-c) were higher in HP positive group than HP negative group (P < 0.05),but there was no obvious difference between the levels of low density lipoprotein cholesterol (LDL-c) in HP positive group and HP negative group.However,in the male subjects,the levels of LDL-c and TC/HDL-c were significantly increased in HP positive group than HP negative group (P < 0.05).HP positive group had a greater risk for high TC/HDL-c both in female and male subjects.In female subjects,the risk for high TC/HDL-c in HP positive group was 1.90 times of that in HP negative group (95% CI,1.06 ~ 3.38).In male subjects,the risk for high TC/HDLc in HP positive group was 1.56 times of that in HP negative group (95% CI,1.21 ~ 2.00).But only in male subjects,the risk for high LDL-c in HP positive group was 2.33 times of that in HP negative group (95 % CI,1.34 ~ 4.06).Conclusions We observed that HP infection was probability associated with dyslipidemia.

Aim To study the effect of [P-(1-Benzotriazole methl)-Benylacrylic acid sodium,abbreviated for BMBS] on experimental arrhythmias. Methods Arrhythmias models induced by drugs in animals were used to observe the effect of BMBS on experimental arrhythmias. Results BMBS 25,12.5 mg?kg -1 iv markedly increased the dose of aconitine for inducing Ventricular premature beats (VP), ventricular tachycardia (VT) and ventricular fibrillation (VF) in rats, as well as that of ouabain for inducing VP, VT, VF and cardiac arrest (CA) in guinea pigs. Also, it postponed the onset time and shortened the duration of arrhythmias induced by barium chloride in rats and decreased the number of animals showing biphasic arrhythmias. Conclusion BMBS has significant effect on experimental arrhythmias.
