The college students innovative test project,which advocates student-centered teaching pattern focusing on questions and subjects is an important component of the project on undergraduate teaching quality and teaching reform in medical college of Shanghai Jiao Tong university.The innovative test project has effectively fostered the innovative spirits,practical abilities,scientific attitudes and learning initiatives of the college students after being implementing for more than four years.Besides,it has changed the teaching philosophy of teachers and created a favorable atmosphere of innovative practice.Several problems have emerged during the implementation of the project including broad topics,limited sample size and incorrect motives for doing tests.Exclusive mechanism aiming at the long-term effect of the project should be established, the concept of the project should be promoted and the communication platform should be built in order to consummate this project.

BACKGROUND:The rapidly developed transplantation of peripheral blood stem cells have been successfully used to substitute bone marrow transplantation and become the first choice method for transplantation of hemopoietic stem cells.It is relatively difficult to collect peripheral blood stem cells from young age and low body mass infants.OBJECTIVE:To investigate the safety and adverse effects of peripheral blood stem cell collection from young age and low body mass through the use of blood cell separator.METHODS:Two type 1 diabetes mellitus infants,aged younger than 2 years old and with body mass less than 15 kg,were treated using autologous hemopoietic stem cell transplantation.The two infants were adequately comforted to lesion the fear of collection.At 1 week prior to collection,calcium agent was orally taken to reduce the incidences of low calcium.Within 24 hours prior to collection,oily food was forbidden,and on the day of collection,milk was forbidden,to avoid chylemia,which influences blood collection.Prior to collection,200 mL 25 Gy y-ray radiated red blood cells suspension was injected into the tube,which was routinely placed in the subclavian vein,to avoid hypovolaemic syndrome and the effects on hematocrit.Individualized collection parameters were set,During collection,blood circulation volume was 3,4 times of systemic blood circulation to ensure sufficient total circulation volume.During isolation,the ratio of ACD to whole blood was kept between 1:11 and 1:13 to prevent sodium citrate poisoning.RESULTS AND CONCLUSION:Peripheral blood stem cells were successfully collected during first intention in each infant.During collection,stable vital signs but no adverse effects were observed.After collection,mononuclear cells weighted 14.71×108/kg and 18.82×108/kg respectively,and CD34+ cells were about 34.13×108/kg and 32.38×106/kg,respectively in each infant.Therefore,it is feasible to collect peripheral blood stem cells from infants of young age and low body mass under sufficient psychological preparation.

Based on the software of traditional Chinese medicine inheritance support system (TCMISS), this article aims to analyze the experience and composition rules for cough from the descendant of Meng He Medical School, Xu Di-hua. The cough cases treated by Xu Di-hua were collected, and recorded into TCMISS (V2.0). Data mining methods such as Apriori algorithm and complex system entropy cluster were used to analyze the medication principles of Xu Di-hua for cough from pathogenesis and therapeutie aspects, and dig out the frequency of the herbs in prescription, core medicine and new combinations. The experience of curing cough from Professor Xu Di-hua were well found in the research. He is good at choosing prescriptions accurately, and pays attention to simultaneous use of cold and moisture drugs with combination of tonification and purgation. He is skilled in adding or reducing materia medica flexibly, as well as regulating lung to relieve cough and eliminating phlegm by clearing heat.

Objective To explore the effect of ciliary,neurotrophic factor (CNTF)-coated polyglycolic and polylactic acid (PGLA) nerve conduits treated by pulsed plasma to repair canine tibial nerve defects. Methods A 2.5 cm long tibial nerve defect was made in eighteen cross-bred dogs.The nerve defects were re- constructed by three different methods:group A:pulsed plasma treated and CNTF coated PGLA nerve conduits (n=6);group B:PGLA nerve conduits alone (n=6);group C:nerve autografts (n=6).HE staining, Massons' trichrome staining,S-100 immunostaining,electrophysiological test and axon counting were used to evaluate the results of nerve regeneration in three groups.In addition,the dynamic walking pattern was recor- ded individually.The observation period lasted for three months.Results All nerve conduits were well vas- cularized and mostly degraded as well as absorbed.It was found that the regenerating axons could traverse all nerve conduits.In regard to nerve conduction velocity and axon counting there was no significant difference be- tween group A and group C (P＞0.05),while the data of group A and group C were significantly better than those of group B(P＜0.05).The dogs in group A and C recovered nearly normal walk pattern while those in group B were still crippled.Conclusion Pulsed plasm-treated and then CNTF-coated PGLA nerve conduits could effectively repair 2.5-cm-long canine tibial nerve defects,and the effect is similar to that of autografts.

Objective The role of long non-coding RNA Linc00467 in human lung adenocarcinoma is not yet clear.This study was to investigate the expression of long non-coding RNA Linc00467 in human lung adenocarcinoma, its clinical significance, and the effects of Linc00467 on the functions of the tumor and endothelial cells in vitro.Methods Lung adenocarcinoma tissue and normal tissue surrounding the malignance were obtained from 60 patients with pathologically proved stage I-Ⅲa lung adenocarcinoma.Human umbilical vein endothelial cells (HUVECs) were transfected with the over-expressed plasmid pccl-Linc00467 (HUVEC experimental group) or the empty vector pccl (HUVEC control group), A549 cells with Linc00467-siRNA (A549 experimental group) or negative siRNA (A549 control group), and H1299 cells, too, with Linc00467-siRNA (H1299 experimental group) or negative siRNA (H1299 control group).The expression level of Linc00467 in the lung adenocarcinoma tissue was detected by qRT-PCR with an analysis of its correlation with the clinicopathological characteristics of the patients;the influence of Linc00467 on the proliferation of the A549, H1299 and HUVEC cells was assayed with CCK-8;and the role of Linc00467 in the angiogenesis of the HUVECs was assessed by fibrin bead sprouting assay.Results The expression of Linc00467 in the lung adenocarcinoma tissue was 2.72±1.31 times as high as that in the normal lung tissue (P<0.01), and those in the A549 and H1299 cells were 3.45±0.25 and 3.22±0.33 times as high as those in the human bronchial epithelial (HBE) cells (P<0.01).The expression level of Linc00467 was significantly correlated with the tumor size and vascular invasion (P<0.05).After transfection of Linc00467-siRNA, the expressions of Linc00467 in the A549 and H1299 experimental groups were down-regulated by 72% and 68% as compared with those in the A549 and H1299 control groups (P<0.01).The number of living cells was remarkably decreased in the A549 experimental group in comparison with the A549 control at 48 h (1.29±0.07 vs 1.51±0.09), 72 h (1.53±0.15 vs 2.13±0.11), and 96 h after culturing (1.98±0.18 vs 3.02±0.12), and so was it in the H1299 experimental versus the H1299 control group, but markedly increased in the HUVEC experimental versus the HUVEC control group (P<0.05).At 5 days, HUVEC experimental group, as compared with the HUVEC control, showed a significantly increased number of newly formed vascular branches (7.36 vs 4.25/superbead, P<0.01) and relative length of the blood vessels (3.12 vs 1, P<0.01).Conclusion Linc00467 promotes tumor cell proliferation and angiogenesis and is highly expressed in the lung adenocarcinoma tissue, which is correlated with the tumor size and vascular invasion and suggests that Linc00467 could be a potential biomarker and therapeutic target.
