BACKGROUND: The main difficulties of whole-cell patch clamP are cell culture and whole-call current recording. OBJECTIVE: To reduce the difficulty of patch-clamp experiment by combining acute cell isolation with current separation technique. METHODS: A total of 40 wistar rats aged 4-7 days, irrespective of genders, were selected. The pallium of wistar rats were cut into slices with 400-600 μm, rested for 1 hour in artificial cerebrospinal fluid with gas mixture, simultaneously put in oxygen. The brain tissues were placed into artificial cerebrospinal fluid containing 16 u/mL(type X) and 2 u/mL(type XIV) proteinase, incubated for 60 minutes, and cleared the digestive enzyme. Under the whole-cell voltage clamp mode, the potential was hold at -80mV, depolarizing pulse stimulation from -60 mV to 60 mV, 10 mV step and 160 ms width. The total Tran membranes current was recorded, and then 70 mmol/LCsCI, 70mmol/L CsF was 11 μmol/L Na~+ channel blockers tetrodotoxin, 30 mmol/L tetraethylammonium, 1 mmol/L 4-AP was successively added into extracellular fluid. The inward sodium current, transient outward potassium current and delayed rectifier potassium current was recorded, and then the result was analyzed using clampfit. MAIN OUTCOME MEASURES:①Cell morphological observation; ②Whole-ceil current recording;③Inward sodium currentrecording; ④Outward potassium current recording.RESULTS AND CONCLUSION: The cell had clearly three-dimensional structure, smooth surface and whole neurodendrite or neuraxon. The cell viability could maintained for 8-10 hours at 25 ℃ temperature. The added 11 tetrodotoxin in extracellular fluid could block sodium Current. The outward potassium current could be blocked by tetraethylammonium with 30 mmol/L and 4-AP with 1 mmol/L. The calls harvested by modified rapid dissociation have good functions. Using current separation method, only specific blockers are needed, without extracellular fluid or electrode solution replacing, which can record the inward sodium current, transient outward potassium current, as well as delayed rectifier potassium current. This method can obviously improve the work efficiency than traditional one.

The invasion and metastasis of tumor as the primary cause of death in cancer increases not only the patient's suffering, but also the difficulty of clinical treatment. It is an important guiding to find the molecular biological tumor markers and gene targets of antirecurrence and antimetastasis for clinical treatment. The invasion and metastasis of tumor is a complex process including the biological characteristics of the cancer, interaction among host cells, extracellular matrix and cancer cells, etc. Recently, epithelial mesenchymal transition (EMT) is becoming a hot spot in oncology research by virtue of its effect on genesis and development of tumor. Currently, the known markers of EMT include epithelial marker proteins mainly containing E-cadherin and interstitial marker proteins mainly containing N-cadherin and vimentin. It is necessary to make a summary among the studies on three proteins.

Objective To investigate the effect of edaravone on the JAK2/STAT3 signaling pathway after ischemia-reperfusion injury in donor rat liver under different cold ischemia times. Methods A total of 102 SD rats were randomly divided into sham operation group,control group and experimental group. Six rats were in sham operation group with free liver operation and no transplantation. Forty-eight rats were in control group and experimental group respectively, and divided into subgroups according to the different cold ischemia times (30 min, 6 h, 12 h and 18 h). There were 6 donors and 6 recipients in each group. The rat model of orthotopic liver transplantation was established by modifiedtwo cuff method. All the donors were perfused by abdominal aorta and the warm ischemia time was 3-5 min. After different cold ischemia times, the experimental group was treated with edaravone (3 mg/kg) at 5 min before the opening of the new hepatic artery, and control group was injected with 3 mg/kg saline. Recipients of each group were sacrificed after 6 h. Finally, real-time fluorescence quantitative PCR was used to analyze the relative expression of JAK2/STAT3 mRNA of donor liver. Results The GAPDH gene and JAK2/STAT3 were well amplified. Under the same cold ischemia time, compared with the control group, the relative expression of JAK2/STAT3 was significantly decreased in the experimental group (P<0.05). With the prolongation of cold ischemia time, the relative expressions of JAK2 and STAT3 mRNA showed a decreasing trend in control group and experimental group, while the relative expression of JAK2 mRNA increased first and then decreased in the experimental group (P<0.05). Conclusion Edaravone has a protective effect on transplanted donor liver during different cold ischemia times, and extends the cold ischemia time for 18 h, which may be related to the inhibition of JAK2/STAT3 signal transduction pathway.

This article analyzes the limitations of traditional medical theory teaching, and proposes the strategies for cultivating medical students' autonomous learning ability, i.e., informatization-based flipped classroom, problem-oriented teaching, mind mapping training, semi-open book examination, exploitation of the clinical and scientific thinking, and practice activities of medical humanities. The strategies of "problem oriented teaching" and "mind mapping training" were integrated into the practice teaching of hematology. Compared with the traditional medical teaching mode, students' feedback after class showed that the teaching mode incorporating new cultivation strategies was more conducive to the improvement of students' self-learning ability ( P = 0.008), and their satisfaction with teaching mode, learning interest, and self-learning ability were all improved. Thus, the appropriate application of the above strategies can help improve students' autonomous learning ability and optimize the effect of medical theory teaching.

Objective:To investigate the mechanism of Xianglian Huazhuo Decoction in treating chronic atrophic gastritis (CAG) rats by detecting the protein and gene expressions of Wnt1, GSK-3β, β-catenin in Wnt signaling pathway.Methods:Totally 60 Wistar rats were randomly divided into blank group and model group. The CAG model was established by MNNG free drink combined with sodium salicylate gavage combined with abnormal hunger and satiety. After model establishment, the rats were randomly divided into model group, Xianglian Huazhuo Group and folic acid group. Folic acid group received the folic acid water solution 1.3 mg/kg for gavage; the Xianglian Huazhuo Group received Xianglian Huazhuo Decoction 15.5 g/kg for gavage; the blank group and the model group received the same volume of purified water for gavage. After 8 weeks of intervention, the general state and the atrophic degree of gastric mucosa were observed. The expressions of Wnt1, GSK-3β and β-catenin were detected by immunohistochemical method, and the mRNA expression of β-catenin expression was detected by real-time quantitative polymerase chain reaction PCR.Results:The general condition of rats in Xianglian Huazhuo group was improved, the atrophy of gastric mucosa was improved, and the effect was better than that in folic acid group. Compared with the model group, the positive area ratio of Wnt1 decreased in Xianglian Huazhuo group ( P<0.05), and the positive area ratio of β-catenin decreased in folic acid group and Xianglian Huazhuo group ( P<0.05 or P<0.01), the positive area ratio of GSK-3β increased ( P<0.05), and the β-catenin mRNA level of Xianglian Huazhuo group decreased ( P<0.05). Conciusion 　Xianglian Huazhuo Decoction may increase GSK-3β by downregulating abnormal expression of Wnt1, promoting β-catenin to degrade normally, thereby blocking the abnormal activation of the Wnt signaling pathway, delaying or reversing CAG carcinogenesis to a certain extent, and exerting therapeutic effects.
