Flipping the classroom is a new teaching mode in which the students learn some-thing through the network autonomous learning before class, in classroom students interact with teach-ers, internalized and absorb what they have learned, and then consolidate it after class. So it can resultin real-timeevaluation of learning effect by different means, different objects and form and can ef-fectively give secondary feed back comments, which has important significance for the improvement of teaching and learning effects at all levels. Article discusses how to effectively use formative assess-ment method to conduct effective monit oringand feed back to improve the flipped classroom activi-ties. It also explore show to strengthen and exercise their student's ability in the application process.

Neurodegenerative diseases,which are common nervous system diseases,seriously affect people''s life quality and even lives. So the pathogenesis of neurodegenerative diseases is attracting more and more attention in recent years. People gradually realize that endoplasmic reticulum stress is associated with the pathogenesis of many diseases through studying the function of the endoplasmic reticulum. Neurodegen-erative diseases, endoplasmic reticulum stress,unfolded protein responsewere used as the key words of retrieval performance in the databases such as Pubmed,CNKI and so on. And the papers which closely re-lated with the theme were chosen to investigate the association between alzheimer''s disease,parkinson''s dis-ease,Huntington'' s disease ,amyotrophic lateral sclerosis and ERS. It turned out that the expression of mo-lecular chaperone GRP78/Bip was increased in all neurodegenerative diseases, and the phosphorylation of eIF2α increased in most neurodegenerative diseases. However, the expression of some ERS-related factors was completely different in different neurodegenerative diseases. Thus,the study of ERS may be an important breakthrough for the pathogenesis and treatment of neurodegenerative diseases.

Objective To discuss the clinical feature and the treatment of severe hand, foot and mouth disease (HFMD), and provide the basis for control of the disease. Methods The clinical data of 60 children with severe HFMD were retrospectively analyzed. Results All the 60 cases appeared fever and the erythra in hand, foot, mouth and gluteal region. Part of the children appeared jumping, body shaking, poor spirit and/or sleepiness. Some children appeared convulsion, and neurogenic pulmonary edema, pulmonary hemorrhage, cardiorespiratory failure happened in 2 critical severe cases. The children were given the comprehensive treatment including ribavirin, mannitol, human immunoglobulin and methylprednisolone. Forty-three cases were cured, 15 cases were improved, and 2 cases died. Conclusions Severe HFMD children usually appear critical condition. Early detection of critical signs and correct and effective clinical treatment can promote children's recovery and reduce the mortality rate.

Objective To establish mouse models of total body irradiation (TBI) with different doses of 60 Co radiation combined with skin defect, so as to investigate the influence of TBI on wound healing and the pathophysiological changes in combined radiation injury and skin defect. Methods A total of 180 female Kunming mice were irradiated with a single dose of 4, 6 or 8 Gy 60 Co ray. Within 30 min after irradiation,a full thickness square wounds (1.5cm×1.5cm) was made on the back of mice to establish animal models of TBI combined with skin defect (n=50), another 30 mice with pure skin defect were used as controls (n=30). Mice in each group were sacrificed on the 3rd, 5th, 7th, 10th and 14th day after injury, each time 6 mice, and the full thickness wounds were harvested. Histological method was used to evaluate the changes of inflammatory cells, fibro blasts and new blood capillaries in the wounds. Image analysis system was used to analyze the areas of the residual wounds. The survival rates and body weight changes of mice within 14 days were analyzed in all groups. Results On the 7th and 14th day after injury, the survival rates of mice in the 6 Gy group were 75% and 55%, respectively. While in the 8 Gy group the survival rate of mice was only 33% on the 7th day,and all the animals died by the 10th day. Within 14 days after injury, the body weight loss of mice demonstrated an increasing tendency with the increase of radiation doses (4,6,and8 Gy groups). TBI delayed wound healing in mice with the increase of irradiation dose.The unhealed areas in the 6 and 8 Gy groups were larger than that in the control group on the 2nd day (P<0.01), and that in 4 Gy group was significantly larger than that in the control group on the 8th day (P<0.05). H-E staining showed that the early inflammatory responses were inhibited, the increase of fibroblasts and new capillaries were greatly delayed, and the granulation tissue formation and reepithelialization were slowed down in the TBI group compared with the simple wound group.Conclusion Animal models of TBI with 6 Gy 60 Co ray combined with skin defect can serve as a platform to study the mechanism of difficult healing and early treatment of radiation injury combined with skin defect.

Objective To observe whether the bone marrow stromal cells (BMSCs) which carry BMP-2/Tet-on genes and are microcapsulated by alginate polylysine alginate (APA) and seeded onto calcium phosphate cement (CPC) scaffolds can express bone morphogenetic proteins-2(BMP-2) and secrete collagen proteins.Methods The BMSCs from rats were prepared,transfected with adenoviruses carrying BMP-2/Tet-on genes,and then microcapsulated by APA.Eight porous CPC scaffolds were prepared and mounted onto a 12-hole plate.The experiment was conducted in 3 groups,with 4 parallel specimens in each group.Microcapsulated BMSCs with the target gene were seeded onto the CPC scaffolds in the experimental group; the transfected BMSCs were seeded into the plate holes as positive controls; APA microcapsules without cells were seeded onto the CPC scaffolds as blank controls.The culture medium in each group was taken for ELISA examination on 3,6,9 and 12 days to evaluate the BMP-2 concentrations respectively.The samples in the experimental group were fixed,sliced and dyed to observe secretion of collagen.Results On 3,6,9 and 12 days after culture,the BMP-2 concentrations were 4713.98 ± 178.50 μg/mL,3288.85 ± 194.38 μg/mL,1292.25 ± 300.11 μg/mL and 337.19 ± 84.49 μg/mL respectively in the experimental group; 4663.87 ±242.99 μg/mL,3250.67 ±293.72 μg/mL,1276.74 ± 157.10 μg/mL and 293.65 ±92.48 μg/mL respectively in the positive controls; 105.14 ± 10.93 μg/mL,91.42 ± 18.00 μg/mL,89.63 ± 12.99 μg/mLand 108.72 ± 23.90 μg/mL respectively in the blank controls.There were significant differences between the 3 groups at each same time point (P ＜ 0.05).The blank controls were significantly different from both the experimental group and the positive controls (P ＜ 0.05),but there were no significant differences between the experimental group and the positive controls (P ＞ 0.05).Collagen fibrils were observed by optic microscopy in the sections of the experimental group.Conclusion As microcapsulated BMSCs can survive in CPC scaffolds and express a significant amount of BMP-2 and secrete collagen proteins as expected,they can be used for further experiments in vivo.

Objective To observe the changes and clinical significances of ischemia modified albumin (IMA),cardiac triponin T (cTnT) and creatine kinase MB (CK-MB) in transient myocardial ischemia induced by radio frequency ablation ( RFA ) in patients with arrhythmia.Methods One hundred and twelve patients with arrhythmia undergoing RFA and 91 patients undergoing CAG were evaluated with blood levels of IMA,cTnT and CK-MB before and 3 and 6 hours after operation.Results Serum levels of IMA at 3 h [ (80.62 ± 7.53 )U/ml ] and 6 h [ (76.37 ± 9.21 ) U/ml ] after operation rose significantly (P ＜ 0.05 ) in the 112 cases of RFA compared with the preoperative [ ( 45.42 ± 7.00 ) U/ml ].While the levels of IMA were not significantly different at 3 and 6 hours after CAG in the 91 patients compared with before sugery ( P ＞ 0.05).The levels of cTnT and CK-MB remained unchanged between the two groups after the procedures ( P ＞ 0.05 ).Conclusion The levels of IMA were quickly increased after myocardial ischemia induced by RFA and this change occurred earlier than that of cTnT.IMA is an early diagnostic biochemical marker of myocardial ischemia.

Objective To observe the effects of comprehensive psychological interventions in the treatment of abnormal blinking in children.Methods One hundred and sixty-three children diagnosed with abnormal blinking were randomly assigned into a basic treatment group or a comprehensive psychological intervention (CPI) group.Both groups received etiology-based therapy,while the CPI group received CPI in addition.After follow-up for six months,the therapeutic effectiveness and recurrence were evaluated.Results Abnormal blinking was significantly reduced in both groups after treatment,but the CPI group showed significantly better effectiveness than the group which received only basic treatment.Furthermore,the CPI group showed significantly less recurrence at 3-and 6-month follow-up.Conclusion CPI is more effective than basic treatment in treating abnormal blinking among children and results in less recurrence.
