Purpose: Set up a new technique to reproduce the cavitation effect in the process of brain deceleration impact Methods: A transparent physical brain model with tiny air bubbles was built and loaded on an upright brain deceleration impacting moveable platform. Then, in the high strength lighting circumstance, the moveable platform was made to free fall from a height of 40cm and impacted on a fixed platform, and the whole deceleration impacting process was recorded by a high-speed video camera. Using the serial pictures analysing software, the volume and mean pressure change of the air bubbles were calculated and the cavitation effect of the brain tissue during the impact was studied. Results: The volume of the air bubble in the contrecoup site increased obviously in the impacting process, the volume of the air bubble in the coup site decreased in the impacting process and the volume change of the air bubble in the middle site was not evident enough in the impacting process. Conclusion: The results proved the negative pressure and the cavitation phenomenon in the contrecoup site. The experiments explicitly and directly showed the cavitation effect in the contrecoup site during the decelerating impact It was helpful to better understand the distribution characters of the dynamic stress of the brain tissue in the brain decelerating impact in a certain extent, and it could also provide some methods and experimental foundation to clarify the mechanical mechanism of the brain contrecoup injury which was often taken place in traffic accidental injury. Besides, the methods were of significance to research the biomechanism, diagnosis and prevention of the brain deceleration impacting injury.

Objective to research the mechanical style(compressive or tensile force)of the key site of brain tissue in brain deceleration impact.Method a transparent physical brain model with air bubbles was built and loaded on an upright brain decaler ation impacting expedmentel platform.Then,the moveable platform was made a free fall from a height of 400mm and impacted on the fixed platform,and the whole deceleration impacting process was recorded by a high-speed video camera.Using the serial pictures analyzing Software,the length change of the long ads(vertical to the impacting direction)and the short axis(in the impacting di-rection)of the air bubbles were analyzed and calculated.Result the length change of the long axis of air bub-ble with in site coup was smallerthan the absolute value of that of the short axis;while with the air bubble in the contrecoup site,the length change of the long axis was bigger than the absolute value of the short axis.Conclusions the results showed that the air bubble in the coup site mainly suffered from the tensile force vertical to the impacting direction and the air bubble in the contrecoup site mainly suffered from the compres-sive force in the impacting direction.Since the propeny of tensile resistance of the brain tissue is inferior to the property of compressive resistance of the brain tissue, the injury is often easier to occur in the contrecoup site than in coup site. The results were of significance to the research of biomechanical mechanism, diagnosis and prevention of the brain deceleration impacting injury.

Objective To understand the screening results and positive lesion situation of colonoscopy screening among high risk urban population of colon cancer in Chongqing Nan'an District to provide a basis for the community heath guidance.Methods The high risk subjects of colon cancer screened according to the item of the Early Diagnosis and Early Treatment of China Urban Cancer and in our center for completing colonoscopy screening during 2013-2016 were collected and analyzed on the positive rates of various lesions.Results A total of 435 subjects were included,141 positive cases were found with the total positive rate of 32.41% (141/435),in which 75 cases were male positive with the positive rate of 47.47% (75/158),and 66 cases were female positive with the positive rate of 23.83 % (66/277),the polyps detective rate was 28.27 % (123/435),tumor-like lesion detective rate was 7.59%(33/435),the adenocarcinoma detection rate was 0.46% (2/435);the total positive rate of male was higher than that of female(x2 =25.669,P<0.01).Conclusion The sequential screening mode in which the high risk population preliminarily screened out by community then performs colonoscopy examination has an important significance for discovering the intestinal tract lesion.

Objective: To observe the therapeutic efficacy of acupoint application at different groups of acupoints in treating bronchial asthma in remission stage. Methods:A total of 120 patients with bronchial asthma in remission stage were recruited and divided by the random number table method into acupoint application group 1, acupoint application group 2 and acupoint application group 3, with 40 cases in each group. In all the three groups, Tiantu (CV 22), Dazhui (GV 14) and Feishu (BL 13) were selected, with Dingchuan (EX-B 1) added in acupoint application group 1, Shenshu (BL 23) added in acupoint application group 2, and Gaohuang (BL 43) added in acupoint application group 3. Before intervention, one month and 3 months after intervention, clinical symptoms, peak expiratory flow (PEF) andforced expiratory volume in 1 second percentage of predicted value (FEV1%) of the three groups were observed, and their clinical efficacies were evaluated. Results: Comparing the therapeutic efficacy regarding traditional Chinese medicine symptoms and signs, after 1-month treatment, the total effective rate was 87.5% in acupoint application group 1, versus 62.5% in acupoint application group 2 and 55.0% in acupoint application group 3, and the between-group differences were statistically significant. After 3-month treatment, the total effective rate was 95.0% in acupoint application group 1, versus 70.0% in acupoint application group 2 and 65.0% in acupoint application group 3, and the between-group differences were statistically significant. After intervention, the three groups all showed significant improvements in pulmonary function with statistical significance; among the three groups, the improvement in acupoint application group 1 was more significant than that in the other two groups. Conclusion: Tiantu (CV 22), Dazhui (GV 14) and Feishu (BL 13) as basic prescription plus Dingchuan (EX-B 1) can improve symptoms of bronchial asthma in remission stage, and it works better in improving pulmonary function than the basic prescription plus Shenshu (BL 23) or Gaohuang (BL 43).

Objective To investigate the relationship of impact stress distribution and stress wave dissemination with temporal bone fracture. Methods Twelve donated fresh corpse were selected and impacted with driving force of 800 kPa, 1 200 kPa and 1 400 kPa to establish the model of impact temporal bone fractures. With aid of three-dimensional stereochemical structure image of 64-slice CT, the vitodynamic distribution and dissemination of impacted temporal bone was calculated by using computer simulation. Results (1) The instant velocity, acceleration and energy of impact as well as displace-ment scope of the hammer increased with higher driving force in the tempus. (2) Instantaneous impact of the temporal bone resulted in Von Mises stress concentration area around the impact point. The stress was weakened suddenly in the skull-brain tissue coupling place but later accumulated in the skull base. (3) Only ipsilateral linear fracture occurred when the driving force of impact was 800 kPa. While impact dif-ferent degrees of depressed fractures could be seen and one case showed secondary fracture of the opposite side when the driving force of impact was 1 200 kPa. The impact with driving force for 1 400 kPa begot complex ipsilateral fractures, secondary fracture of the opposite side and skull basal fracture. (4) Frac-ture line of the temporal bone accorded with impact stress concentration area. Conclusions All pa-rameters, stress distribution and dissemination of impact are in accordance with temporal bone fracture during impaet process of the temporal bone, which is of vital significance for diagnosis and protection of impact temporal bone fractures.
