In this paper, an experimental analysis of overcoming obstacle in human walking is carried out by means of a motion capture system. In the experiment, the lower body of an adult human is divided into seven segments, and three markers are pasted to each segment with the aim to obtain moving trajectory and to calculate joint variation during walking. Moreover, kinematic data in terms of displacement, velocity and acceleration are acquired as well. In addition, ground reaction forces are measured using force sensors. Based on the experimental results, features of overcoming obstacle in human walking are ana- lyzed. Experimental results show that the reason which leads to smooth walking can be identified as that the human has slight movement in the vertical direction during walking; the reason that human locomotion uses gravity effectively can be identified as that feet rotate around the toe joints during toe-off phase aiming at using gravitational potential energy to provide propulsion for swing phase. Furthermore, both normal walking gait and obstacle overcoming gait are characterized in a form that can provide necessary knowledge and useful databases for the implementation of motion planning and gait planning towards overcoming obstacle for humanoid robots.

AIM To recognize the characteristic findings of micrQliver cancer (MlC) and to evaluate the effect of CT arterial portography (CtaP) and CT hepatic arteriography (CTHA) in diagnosis of MlC. METHODS Between April 1996 to December 1998, CtaP and CTHA were performed in 12patients with MlC, which were not detect ed byconventional CT examinations. After CTHA, 3 ml-- 5 ml mixture of lipiodol, doxorubic in andmitomycin C were injected into hepatic arterythrough the catheter, and then followed up by CTthree or four weeks later (lipiodol CT lP-CT).RESUlTS A total of 22 micro--tumors (0 .2 cm 0.6 cm in diameter ) were detected in 12patients, which manifested as small perfusiondefects in CtaP and small round enhancement inCTHA. The rate of detectability of CtaP andCTHA was 68.2% (15/ 22) and 77.3% (17/ 22)respectively, and the rate of the simultaneoususe of both procedures reached 86. 4% (19/ 22 ).All micro--tumors were demonstrated as punctatelipiodol deposit fool in lP--CT. After lP--CT, theelevated serum level of Q-fetoprotein (AFP)dropped to the normal level in all *** The CtaP and CTHA are the mostsensitive imaging methods for detecting microIiver cancer. Confirmed by the change of theelevated serum AFP level and lipiodol depositfool in lP-CT, small perfusion defects in CtaPand punctate enhancement in CTHA may suggestmicro--liver cancer.

The density seasonal dynamics of Bemisia tabaci med were evaluated over two years in a cotton-growing area in langfang, Hebei Province, northern China on cotton （Gossypium hirsutum l.） and six other co-occurring common plants, common ragweed （Ambrosia artemisiifolia l.）, piemarker （Abutilon theophrasti medicus）, sunflower （Helianthus annuus l.）, sweet potato （Ipomoea batatas l.）, soybean （Glycine max l.）, and maize （Zea mays l.）. The whitefly species identity was repeatedly tested and confirmed; seasonal dynamics on the various host plants were standardized by the quartile method. B. tabaci med appeared on weeds （the common ragweed and piemarker） about 10 days earlier than on cotton, or the other cultivated plants. The peak population densities were observed over a span of 2 to 3 weeks on cotton, starting in early （2010） or mid-August （2011）. The common ragweed growing adjacent to cotton supported the highest B. tabaci densities （no. on 100 cm2 leaf surface）, 12-22 fold higher than on cotton itself. Sunflower supported more B. tabaci than the other plants, and about 1.5-2 fold higher than cotton did, Our results indicate that weeds （esp. the common ragweed） around cotton fields could increase the population density of B. tabaci med on cotton, while sunflower could act as a trap crop for decreasing pest pressure on cotton.

Background: Physical activity(PA) has been shown to benefit cognitive function in older adults. However, the cognitive benefits of exercising for older Chinese adults have not been systematically documented. This study was to conduct a systematic review on evidence that PA is beneficial for cognitive functioning in older Chinese ***: Major databases, including Pub med, EMBASE, Cochrane library, Wan Fang, CNKI, and VIP, were searched for studies published in English or Chinese between January 2000 and December 2015. Randomized and non-randomized controlled trials(RCTs and non-RCTs), cohort,case-control and cross-sectional studies that evaluated PA and cognitive function among older Chinese adults were included in this ***: Of 53 studies included and reviewed, 33 were observational(22 cross-sectional, 7 case-control, and 4 cohort) and 20 were experimental(15 RCTs, 5 non-RCTs). Observational studies showed an association of reduced risk of cognitive-related diseases(i.e., mild cognitive impairment, Alzheimer's disease, and dementia) through PA, whereas experimental studies reported exercise-induced improvement in multiple domains of cognitive function(i.e., global cognitive function, memory, executive function, attention, language, and processing recourse).Conclusion: This systematic review provides initial evidence that PA may benefit cognition in older Chinese adults. Further studies of individuals with cognitive impairments and prospective and RCT studies having high scientific rigor are needed to corroborate the findings reported in this review.

We are reporting over 500 acupuncture cases, a wide range of illnesses ranging from orthopedic, internal, neurological and psychological diseases, all of which were treated with a newly developed and therefore available laserneedle system. This system was highly successful in treatment of a variety of illnesses including HWS, BWS and lWS Syndromes, gonarthritis, coxarthritis, rhizarthrosis, periarthritis of the shoulder, epicondylitis humeri radialis, tendinitis, fibromyalgia and PCP, Morbus Bechterew, paralysis after stroke, migraine and other headache syndrome, tinnitus, trigeminal neuralgia, gastropathy, bronchial asthma, AVK, mental depression and other psychovegatative burnout syndrome by using both body acupoints and otopoints. Treatment was made by simultaneously using 8 laserneedles which were not pricked into, but stuck onto the skin. The laserneedles emit red and infrared laserrays with a high energy output, so that perceptible, vegetative stimulation can be detected at the acupunctrured sites. We found out, that especially in the therapy resistant, long standing cases and cases with chronic back and spine problems, considerable improvements in easing pain and increasing mobility could be made. Recognizable success was made by using laserneedles in cases suffering from psychological illnesses, especially psychosomatic related Burnout syndrome and cases of exhaustion. Usually after 2～3 treatments, efficient success was made, without any side effects what so ever.
