With the development of medical education,the traditional cell biology teaching modes and methods need constant adjustment to adapt to the current teaching.In view of the present high-speed development of cell biology,we seriously picked some representative themes to carry out thematic teaching.Students were encouraged to read some references about the corresponding content and thought primarily before the class.After the lesson,the teacher guided students to discuss and find the answers to the questions they asked before.Participation in class discussion and homework completion accounted for 10％ of the final assessment results.The thematic teaching helped to optimize classical teaching contents and frontier progress.This teaching mode not only stimulated learning interest but also fully exercised learning ability.

Objective • To examine the carotid viscoelasticity by using ultrasonic shear wave dispersion (USWD) technique, and to preliminarily analyze its correlation with blood flow shear rate. Methods • Forty-five patients of General Surgery Department of Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine from December 2018 to January 2019 were recruited, and divided into the elder group (≥ 50 years old) and the younger group (<50 years old) according to the median age. The carotid viscoelasticity of the patients was examined by USWD technique and the indexes were obtained, including carotid shear wave elasticity (SWER), shear wave dispersion (SWDR), blood flow maximum shear rate (SRmax) and mean shear rate (SRmean). The correlations between SWER, SWDR and blood flow shear rate were analyzed by Pearson correlation, respectively. Results • ① Compared with the younger group, the carotid artery SWER, SWDR, SRmax and SRmean of the patients in the elder group were lower (all P<0.05). ② The SWER and SWDR of carotid artery of all patients were positively correlated with SRmax and SRmean, respectively (all P<0.05). Conclusion • Carotid arterial viscoelastic index based on USWD technique is closely related to the blood flow shear rate, which is expected to provide a new perspective for the study of carotid arterial diseases.

BACKGROUND: This study was undertaken to measure the concentration of adiponectin (APN) in serum and induced sputum in patients with chronic obstructive pulmonary disease (COPD during acute exacerbation (AECOPD) and at stable stage and to determine the role of APN as a marker of inflammation in the pathogenesis of COPD. METHODS: All the patients in this prospective study were enrolled from October 2008 to October 2009, including 30 male AECOPD patients from the emergency department, 30 male stable COPD patients from the department of respiratory diseases, and 30 healthy non-smoking male controls from the department of medical examination. The serum and induced sputum were collected from each patient. All of the patients had normal weight (BMI range 18.5-24.9 kg/m2). Patients with severe bronchial asthma, bronchiectasis or autoimmune disease were excluded. Cell count and classification was performed for the induced sputum. The concentrations of APN, IL-8, IL-6 and TNF-α were measured by ELISA. Pulmonary function was tested among the three groups. Comparisons between the groups were conducted by Student's t test, ANOVA analysis or nonparametric test. Correlation analysis was carried out by Pearson's product-moment correlation coefficient test or Spearman's rank-order correlation coefficient test. RESULTS: The concentrations of APN in the serum or induced sputum in AECOPD patients were significantly higher than those in stable COPD patients or healthy non-smoking controls (P<0.01). The concentration of APN in stable COPD patients was significantly higher than that in healthy non-smoking controls (P<0.01). For the AECOPD patients, APN was positively correlated with IL-8 and TNF-α in the serum and induced sputum (r=0.739, 0.734, 0.852, 0.857 respectively, P<0.05). For the stable COPD patients, APN was also positively correlated with IL-8 and TNF-α in the serum and induced sputum (r=0.751, 0.659, 0.707, 0.867 respectively, P<0.05). In addition, for the AECOPD patients, APN was positively correlated with the percentage of neutrophils in the induced sputum (r=0.439, P<0.05). CONCLUSIONS: APN is involved in the process of systematic and airway inflammation of COPD. This process is related to neutrophils in the airway, IL-8 and TNF-α. APN could be used as a new marker for inflammation of COPD.

Background Sweep pattern visual evoked potential (SVEP) is an objective method of visual test.There is a clear correlation between SVEP acuity and subjective vision,but they are not identical.Recent studies showed that new regression method can improve the accuracy of SVEP acuity. Objective This trial was to investigate and compare the outcome between amplitude-spatial frequency (A-SP) regression method and amplitudelogVA (A-logVA) regression method in extrapolating the SVEP acuity.Methods SVEP was recorded in 113 eyes of 64 subjects using GT-2000 ( Guo Te,China) with the gratings of 10 different spatial frequency from 0.99 to 12.89 cpd as stimulus.The 1 13 eyes included cataract,glaucoma,corneal disease,optical neuropathy,retinal disease,ocular trauma,refractive error and normal eyes.The correlation were analyzed of SVEP acuity,decimal visual acuity and LogMAR visual acuity.The response were averaged and DFT on the monitor display.SVEP acuity was calculated by extrapolating 0 response amplitude.Results The correlation indices of decimal visual acuity curves obtained by the A-logVA function was 0.663,and that obtained by the A-SP function was 0.705.The positive correlation was seen between subjective decimal visual acuity and A-logVA decimal visual acuity (r =0.540,P＜ 0.01 ) and between subjective decimal acuity and decimal acuity calculated by the A-SP regression method (r=0.620,P＜0.01 ).SVEP decimal acuity calculated by the A-SP function regression method was significantly different from the that calculated by the A-logVA function regression method (Z =-8.688,P＜0.01 ).And the correlation indices of LogMAR visual acuity curves obtained by the A-logVA function was 0.733 and that obtained by the A-SP function was 0.715.The positive correlation was found between the subjective LogMAR acuity and that calculated by the A-SP regression method (r=0.700,P＜ 0.01 ) and between the subjective LogMAR acuity and LogMAR acuity calculated by the A-logVA regression method (r=0.710,P＜0.01 ).SVEP LogMAR acuity from A-SP function regression method was significantly different from the LogMAR acuity from A-logVA function regression method (Z=-8.748,P＜0.01 ).No significant differences of VA LogMAR were found in gender,eyes,type of disease and age(x2 =2.171,P=0.338;x2 =0.976,P=0.614;x2 =6.032,P=0.420;x2 =14.720,P=0.257 ).Conclusions SVEP can obtain the visual outcome in human.The amplitude-logVA function regression method is more accurate in extrapolating SVEP acuity.

OBJECTIVE Recent studies have demonstrated that the Nlrp3 inflammasome serve as a central role in the pathogenesis of cardiovascular diseases and endothelial dysfunction occurs in association with several cardiovascular risk factors. Given the demonstrated anti-inflammatory effects of aspirin, the present study was designed to test whether aspirin diminish NLRP3 inflammasome activation and prevent endothelium injury and associated coronary artery damage during LPS. METHODS Mouse carotid arterial endothelial cells (CAECs) were cultured and treated with 0.1-3 mmol·L-1 of aspirin in response to LPS (2 μg·mL-1) stimuli. After 24 h, the Nlrp3 inflammasome complexes consist of varied proteins were analyzed by WB. NO and T-AOC in the supernatant was detected by ELISA. Intracellular reactive oxygen species (ROS) generation for 24 h was observed by DCF fluorescence. The mice were treated with aspirin (12.5 mg·kg-1 per day, 62.5 mg·kg-1 per day, 125 mg·kg-1 per day) and dexametha?sone (0.0182 mg · kg- 1 per day) for 7 d. The level of IL- 1β,IL- 18 protein was detected by ELISA. RESULTS Immunofluorescence results showed the colocalization of Nlrp3 with ASC or caspase 1 decrease in a concentration- dependent manner. Meanwhile, the expression of Nlrp3 and caspase 1 protein was decreased with the concentration of aspirin, but no changes the expression of ASC protein. Nlrp3 protein levels in CAECs were 0.33- 0.8- fold and cle- caspase 1 protein levels in CAECs were 0.48-1-fold compared to those in LPS stimulation when treated with 0.1-3 mmol·L-1 aspirin for 24 h (P<0.01). Aspirin significantly antagonized the effect of LPS on NO (1.22-1.91-fold that of LPS stimulation, P<0.01) and T-AOC expression (1.02-1.90-fold that of LPS stimulation, P<0.01). As the different concentration of aspirin treated, the generation of ROS was 0.51-1.10-fold that of LPS stimulation (P<0.01). In vivo data shown the level of IL-1β, IL-18 protein from serum are in concordance with the level of Nlrp3 inflammasome activation. CONCLUSION We conclude that aspirin has anti- inflammatory properties, protecting CAECs from LPS-induced injury by inhibition of NLRP3 inflammasome activation through ROS pathway.

Objective To assess the new edition of WHO Japanese Encephalitis (JE) Surveillance Standards (WHO Standards) based on syndrome surveillance data and to provide field evidence regarding the standards. Methods Based on syndrome surveillance data, acute encephalitis syndrome (AES) case was categorized, according to the WHO Standards. A cohort study was applied to estimate the AES definition set in the Standard and relative risk was computed to estimate the existence and intensity of statistical correlation between AES and JE cases. Percentage of attributable risk was counted to describe the coverage of AES for JE cases in the studied population. Sensitivity,specificity, Youden index and positive predictive value of AES components were calculated for the purpose of identifying the clinical values under the screening program. Results 1424 suspected cases were evaluated in the surveillance program and 1396 cases with ELISA result, of which 109 positive cases were detected. According to the "standardized" classification, a total of 706 cases in line with AES case deftuition, were categorized into 83 cases of JE, 425 cases of AES unknown and 198 cases of AES other agent. In the cohort study,a relative risk of 4.62 (95% CI:2.80-7.63 ) and the percentage of attributable risk as 78.35% (95% CI: 64.25% -86.89% ) were observed. Conclusion The AES definition for JE was significantly effecting on the screening programs and a strong correlation strength was observed in the study. AES syndrome could cover most of the JE cases. "Convulsions",with appreciative screening value, was recommended to be involved into the new version of the WHO Standards.

In the 1960s, modern science began involving the essence of heat syndrome, but there have still no in-depth systematic studies on pathological mechanisms of heat syndrome and action mechanisms of cold and cool herbs. In this study, the animal model with heat syndrome was set up by feeding herbs with hot property, and then cold and cool herbs was applied in the experimental therapy. The two-dimensional electrophoresis and mass spectrometry technologies were adopted to compare the liver mitochondria proteome of the rats of the heat syndrome model and the ones treated with cold and cool herbs, so as to discover specificity-related proteins after heat syndrome and treatment with cold and cool herbs.
