ObjectiveTo investigate the effects of task-driven teaching mode on physical therapy teaching in higher vocational education. Methods40 students in 2006 rehabilitation class were taught with routine mode as the control group, while 35 students in 2007 rehabilitation class taught with task-driven mode and routine mode as experimental group. ResultsAt the end of the course, the results of examination in theory and practice were better in the experimental group than control group (P<0.01). 85.71%～94.28% students in the experimental group said that the task-driven teaching mode could improve their comprehensive quality especially the skill of practice, as well as the interest and ability of learning. ConclusionTask-driven teaching mode can improve the teaching effect on physical therapy, and received by most of the students.

This article introduced the reform of the teaching mode for Rehabilitation Therapy in higher vocational education, including the course of theory and practice, system of personnel training and assessment.

Objective Platelet aggregation, activation induced by bubbles is the main cause of decompression sick-ness.Clopidogrel(Clo) can decrease platelet aggregation through inhibiting the bind of fibrinogen and ADP .This study is designed to find if Clopidogrel can paly a protective role in decompression sickness and explore the intervention mechanism . Methods Totally 111 male SD rats divided into 3 groups:normal control group (n=20), decompression sickness(DCS) group(n=46), and DCS+Clo(Clopidogrel)treated decompression sickness (DCS+Clo)group(n=45).The rats in DCS and DCS+Clo group were placed in chamber and compressed to 1.5 MPa at speed of 2t/4 , the time of compression and res-idence was 4.5 min totally, then decompressed to surface at a speed of 3 m/s.The mortality and behavioral of rats were ob-served within 30 min post decompression .The pathology and the wet/dry ratio of lung , WBC and platelet counts in periph-eral blood, the expression of activated platelets , and immunohistochemical detection of lung tissue CD 41 expression were also been tested .Results We found Clo reduces the DCS mortality risk ( mortality rate:11/45 in DCS+Clo group vs 28/46 in DCS group, P<0.01).Clo reduced the lung injury, the wet/dry ratio of lung, the accumulation of platelet and leu-kocyte in lung , the WBC counts and activated platelets in peripheral blood .Conclusion Clo can play a protective role in decompression sickness through reducing post-decompression platelet consumption and activation , decreasing the activation of leukocytes .

Physical therapy is one of the core courses of rehabilitation therapy in higher vocational education. This paper would introduce the experience of choice of materials, contents and teachings as well as the teachers construction. Some suggestions in course construction were discussed.

Objective: To investigate the effects of hinokitiol on the proliferative inhibition and apoptosis induction in human clear cell renal cancer 786-O cells. Methods:CCK-8 assays were performed to analyze the effects of hinokitiol on the proliferation of 786-O cells. The apoptosis rate was determined by flow cytometry. EGFP-LC3 microscopy assays were performed to assess the autoph-agy flux. Cleaved Caspase-3, LC3, and P62 were detected by Western blot. Results: Hinokitiol could inhibit the proliferation of the 786-O cells and could induce cell apoptosis via Caspase pathway. Hinokitiol induced the autophagy of 786-O cells, increased LC3 ex-pression, and downregulated P62 expression. Conclusion: Hinokitiol can inhibit the proliferation of 786-O cells and can induce cell apoptosis via autophagy induction.

Objective To investigate the effects of reducing the auditory organ dose by limitation of sub regional auditory organ in IMRT plan. Methods Total 223 cases of nasopharyngeal carcinoma patients were divided into group A and group B. In group A, the IMRT plans of 114 patients were designed by limiting overall auditory organ dose. In group B, the IMRT plans of 109 patients were designed by limiting sub regional auditory organ dose. According to the Clinical prescription, the IMRT plans were designed. Paried t?test was difference between groups. Results By comparing the two groups of auditory organ dose, in all stages, the tympanic cavity Dmean average in group B decreased by T1 vs. 17?? 7%,T2 vs. 22?? 4%,T3 vs. 15?? 7% and T4 vs. 14?? 2% ( P= 0?? 000,0?? 000,0?? 000,0?? 000);cochlea Dmean average decreased by T1 vs. 11?? 0%, T2 vs. 20?? 1%, T3 vs. 10?? 0% and T4 vs. 9?? 0%(P= 0?? 004,0?? 000,0?? 007,0?? 036);vestibule Dmean average decreased by T1 vs. 22?? 6%, T2 vs. 31?? 8%, T3 vs. 20?? 6% and T4 vs. 21?? 4%, significantly less than in group A (P= 0?? 000,0?? 000,0?? 000,0?? 000). The bony portion of eustachian tube Dmean average in group B decreased were not significantly less than in group A (decreased by 3?? 4%,6?? 8%,3?? 6%,0?? 1%;P= 0?? 291, 0?? 006,0?? 155,0?? 963). Conclusions In IMRT plan, optimization on dose limitation of sub regional auditory organs were used to reduce the auditory organ dose and decrease the radiation damage to auditory organ.

Spore surface display is one of attractive microorganism surface display systems. With the advantage of resistance attribute and specific assembly pattern, the technology of spore surface display now is attracting more and more attention. According to the current reports and main achievements of spore surface display, the structure and assembly of spores, the principle for construction and some existing spore surface display systems were elaborated in this paper. Now with the unique property of spores, the technique is not only widely used in production of vaccines but also has great applied potential in the field of biocatalysis and cell-factory.

Objective To investigate the effect of N-acetylcysteine ( NAC) on lung and heart injury of rats with a fast floating escape induced decompression sickness .Methods Eighty male Sprague-Dawley rats were randomly and evenly divided into four groups:control group and three NAC prevention groups .The NAC groups were treated with different doses of NAC(250, 500 or 1000 mg/kg)by intraperitoneal injection 1 h before entrance.In the control group, rats were given an equal volume of saline1h before entrance.The air was pressurized at the 2t/7 exponential rate to 1.5 MPa which was maintained for 4 min and then uniformly decompressed to atmospheric pressure .The extravehicular survival and pathological changes in the lung and heart tissue were detected 0.5 h after rat egress.Results The survival rate of rats treated with NAC 500 mg/kg(90%) was significantly higher than that of those treated with saline (65%)alone (P<0.05).There was large break and fusion in the structure of pulmonary alveolus of control group besides obvious erythrocyte exudation , cardiac muscle fibers edema ,and obvious denaturation and break .Conclusion NAC can play a protective role in rats with a fast floating escape induced decompression sickness by mitigating the injury to and inflammation of lung and heart tissue .

Objective To study the expression levels of microRNA (miR)-16 and miR-146a in rat lungs of decompres-sion sickness (DCS) caused by fast buoyancy ascent escape or diving .Methods At 0.5 h after fast buoyancy ascent es-cape or diving, the pathological changes in rat lungs and expression levels of miR-16,and miR-146a were detected by re-verse transcription-quantitive polymerase chain reaction and compared with normal control group .Results The pathological characteristics of lungs in two DCS groups were tissue damage .At 0.5 h after DCS caused by fast buoyancy ascent escape , the lung tissue expression levels of miR-16 and miR-146a did not significantly change compared with normal control and diving DCS groups ,but the rat lung tissue expression level of miR-146 a in diving DCS group was obviously increased , com-pared with normal control group .Conclusion miR-146a may play a role in post-transcriptional regulation in the process of diving DCS .
