ABSTRACT
Objective To investigate the effect of long-term walking exercise on the health status of low-labor-intensity population under long-term walking exercise.Methods A total of 100 volunteer teachers from universities in Beijing were enrolled.After physical examination,they were randomly divided into control group and observation group.The observation group regularly carried out corresponding encouragingactivities and recorded the daily number of steps.The corresponding indexes were measured again after 450 days.Results 45.24％ participants in the observation group got more than 75％ participation rate.The lower the participation rate,the lower the average daily steps (P ＜ 0.05).The fasting blood glucose,systolic blood pressure,LDL and total cholesterol were lower than other groups in the group participation rate ＜25％ (P ＜0,05).The body mass index,systolic blood pressure,fasting blood glucose,total cholesterol,ratio diabetes and hypertension in low activities group (＜ 7 500 steps/day) were lower than those in other groups (P ＜ 0.05).Conclusions Walking exercise can achieve good long-term persistence with constant feedback.For those who are older and whose initial indicators are higher,participation rate and exercise volume are more likely to be better under the guidance of encouragement.Persisting long-term walking exercise can help reduce blood pressure and blood lipids.
ABSTRACT
Go is not only regarded as the most complex board game, but also viewed as a huge challenge for artificial intelligence (AI). A computer Go program, AlphaGo, using artificial neural networks and tree search defeated one of the best professional human players in March 2016, achieving an unprecedented performance in the game of Go. This victory represented a major milestone in AI research. AI would profoundly affect all fields in the days to come. On the other hand, traditional Chinese medicine (TCM) is thought to be of similar cultural background, traditional concept and way of thinking to Go. Consequently AI techniques may be employed in TCM research. This article presented a brief overview of recent progress in AI, and explored the feasibility of applying the techniques concerning AlphaGo to the diagnosis and treatment of TCM.
ABSTRACT
Objective To investigate the effects of 3-N-butylphthalide ( NBP ) pretreatment on the score of neurological deficit , oxidative stress and pathomorphology in rats with cerebral ischemia reperfusion injury ( CIRI ) . Methods Ninety male SD rats were randomly divided into sham operation group ( Sham group ) , model group ( IR group), NBP pretreatment low dose group (NBPⅠgroup), NBP pretreatment middle dose group(NBPⅡgroup) and NBP pretreatment high dose group(NBPⅢgroup), 18 rats per group.Pretreatment was given once a day within 1 week before establishing the model of cerebral ischemia reperfusion injury .The model of middle cerebral artery occlusion ( MCAO) was subjected by suture method .The score of neurological deficit was executed after ischemia for 2h and reperfusion for 24h in all the rats.The cerebral infarction was observed by TTC staining .The pathologic change of brain was observed by HE staining under the microscope .Hydroxylamine method was used to detect activity of SOD , chemical colorimetry method was used to measure activity of GSH-PX, and TBA method was used to detect content of MDA .Results (1) In Sham group, the score of neurological deficit and the percentage of infarction volume were zero , the morphology of nerve cell was regular , and activity of SOD, GSH-PX and content of MDA of brain tissue were normal .(2) Compared with IR group , the score of neurological deficit was significantly reduced in NBP pretreatment groups (all P<0.01); the score of neurological deficit was decreased progressively in turn in NBP Ⅰ,Ⅱ,Ⅲgroup (all P<0.05).(3) Compared with IR group, the percentage of infarction volume was cut down progressively in turn in NBPⅠ,Ⅱ,Ⅲgroup (all P<0.05), and neuron injury was also induced obviously in NBP pretreatment groups .(4) Activity of SOD, GSH-PX was largely increased , and content of MDA was greatly decreased in NBP pretreatment groups ( P<0.01 ) .Activity of SOD , GSH-PX went up progressively in turn , and contents of MDA were cut down progressively in turn in NBP Ⅰ,Ⅱ,Ⅲgroup ( all P<0.05 ) .Conclusion 3-N-butylphthalide can significantly up-regulate the activity of SOD and GSH-PX, decrease the content of MDA , reduce the percentage of infarction volume , and relieve the damage of nerve cell to preventively protect the rats with cerebral ischemia reperfusion injury .
ABSTRACT
RIA(Rich Internet Applications) have highly interactive, rich user experience and powerful clients. Based on introducing the concept, features, and technology platform of the RIA technology, we proposed that RIA should be the highest priority in hospital medical equipment management information system construction.

<p><b>OBJECTIVE</b>To develop a maintenance management system for medical equipment based on HIS. The system contains some special functions( including preventive maintenance, automatic job dispatch, performance assessment, etc.) which are very useful for confirming the medical equipment in proper conditions and promoting the working efficiency of the staff. The system provides technical support for the improvement of the maintenance management level.</p><p><b>METHODS</b>The system, completed the software design using C/S, B/S combination mode.</p><p><b>RESULTS</b>The system realized clients of various sections of zero maintenance, and make the data manipulation, statistical features of equipment management department more convenient.</p><p><b>CONCLUSION</b>the system connects the subsystems closer and interacts information from time to time, forming a tight network structure. This provides a basis for future hospital-wide information integration.</p>

7 cm in diameter)of the breast were treated in our hospital by lumpectomy via a periareolar incision.The length of the incision was less than half of the perimeter of the areola.For multiple fibroadenomas,circumareolar incision(not longer than half of the nipple-areolar perimeter)was made in different quadrants according to the position of the main tumor,so that the multiple benign tumors could be integrally removed through the approach between the hypodermic fat and glands via radial incisions.Similarly,giant benign tumors were treated through the same approach,cut into pieces,and then removed.Results Totally 165 tumors were removed from the 46 patients with multiple fibroadenomas.In the resected masses,19 were from one patient,who had bilateral multiple breast tumors.The 2 patients with giant breast fibroadenoma were also cured by lumpectomy,the diameter of the largest tumor in the two was 8 cm,while the circumareolar incisions were shorter than 3.5 cm.No nipple necrosis occurred after the operation in our series.Follow-up was achieved in all of the patients for 1 month to 2 years(mean,14.4 months),during which,11 cases showed no incision scar,26 had non-notable scars,9 cases developed observable incision scars,and 2 cases had apparent scars owing to their susceptibility to scar.Conclusions Lumpectomy via minor circumareolar incision is convenient and effective for multiple or giant benign fibroadenoma of the breast with good cosmetic outcomes.
