Authors: ZHANG Li, JING Mingxin, ZHAO Yanling, WANG Li, WANG Xiuzhi
PP: 2511~2514
Abstract: Objective: To analyze the relationship of acupuncture effect and middle frequency (MF) and mean power frequency (MPF) of surface electromyography (sEMG) signal. Methods: Collect the sEMG signals of the middle part of both deltoid muscles when the subjects make both shoulders contract homometrically to the maximum abduction. After 20 min relax, do acupuncture “jian san zhen” (Jianyu/Jianqian/Jianhou) on the left shoulder and collect the signals. Results: There was no significant difference between the signals collected before and after acupuncture on the left shoulder (P>0.05). The MF & MPF decreased significantly on the right shoulder (P<0.05). The correlation coefficient between deltoid fatigue and acupunctural effect r=0.951 54. Conclusion: the sEMG signals reflect the acupunctural therapeutic effects. MF & MPF decline in the case of deltoid fatigue, while increase after the acupuncture. There is a positive correlation between the function of muscles and the acupunctural effect. Acupuncture can be used to treat muscle fatigue and stop muscular pain and dysfunction. The MF & MPF can be considered as one of the objective indicators to test acupunctural effect.

Title: Clinical study of relevance of stroke syndrome of wind phlegm with blood stasis and seasonal changes of weather
Authors: ZHANG Liangdeng, HE Qingyong, ZHANG Ji
PP: 2496~2500
Abstract: Objective: To study the relevance of stroke syndrome of wind phlegm with blood stasis and seasonal changes of weather by the average bimonthly clinical data (six steps) in Beijing area. Methods: 305 cases of stroke syndrome of wind phlegm with blood stasis were classified by six steps, and were analyzed in the relevance of six qi (six climatic factors), gender, time, month, age and stroke syndrome of wind phlegm with blood stasis. Results: Stroke syndrome of wind phlegm with blood stasis is most likely to occur in the cold seasons, especially cerebral infarction and cerebral hemorrhage, while other strokes (subarachnoid hemorrhage, unexplained stroke, etc.) were most likely to occur in the wind seasons; there were more male patients than female; and the older age groups particularly those 66~76 years old occurred stroke syndrome of wind phlegm with blood stasis at greatest probability. Conclusion: Due to lack of body vital qi, six qi becomes evils. Cold evil taking with wind evil causes phlegm and blood stasis, blocks brain meridians and collaterals, thus occurs stroke syndrome of wind phlegm with blood stasis, which is one of main pathogenesis of stroke syndrome of wind phlegm with blood stasis which is at high incidence in cold season in Beijing area.

PP: 2489~2495
Abstract: Objective: To observe the intervening effect and acting mechanism of Bushen Kangshuai tablet (BKT) on rabbit\\\'s atherosclerosis (AS). Methods: Thirty-six male Japanese white rabbits were randomly assigned into four groups: control group, model group, and the simvastatin group the BKT group. The AS model was established. The medication of simvastatin and BKT was given in the whole 10-week course. Levels of blood lipid, interleukin-1(IL-1), monocyte chemotactic protein-1 (MCP-1), and tumor necrosis factor-α (TNF-α) were measured. The nuclear factor-kappa B (NF-κB) expression in aortic wall, ratio of plaque area to intimal area (PA/IA), intimal thickness (IT), and intimal hyperplasia index (IHI) were measured at the terminal of experiment. Results: Compared with the normal control group, all indexes of the blood lipids and inflammation factors measured at various time points, and the PA/IA, as well as IHI in the model group were higher (P<0.01). Compared with the model group, the levels of IL-1, MCP-1, TNF-α, NF-κB as well as the ratios of PA/IA and IHI were lower in the two treated groups at all time points after treatment (P<0.01 or P<0.05). Conclusion: BKT can suppress the inflammation reaction in rabbits to prevent AS formation, and the action is not directly correlated with the blood lipids level.

Authors: RONG Xiumei, LI Dongyun
PP: 2480~2488
Abstract: Therapeutic interventions on cancer-related anemia in clinic mainly include blood transfusions, administration of recombinant human erythropoietin (rHuEPO) and herbs. Studies show that, erythropoietin (EPO) is the best therapeutic tool up to now, and it can improve the HGB effectively, however, there are some experts hold different ideas about the safety and effect, which needs to be further discussed. Blood transfusion can remedy anemia soon, however, it can not sustain long. Traditional herbs have been demonstrated in effect in clinic studies, but its extensional mechanism is not clear. The occurrence and treatment of cancer-related anemia are shown from the views of integrated traditional and western medicine in this paper. And safe, effective and economical methods are expected to be discovered, so the patients\' life can be prolonged and quality of life can be improved.

Authors: YIN Ming, XIONG Hui, HE Lizhi
PP: 2474~2479
Abstract: Objective: To establish an animal model of osteoarthritis (OA) in rat knee joint so as to provide a basis for the rehabilitative intervention of OA. Methods:20 μL mixture of 4% papain solution and 0.03 mol/L L-cysteine solution was injected into articular cavity of 20 Sparague-Dawley (SD) rats on the first, third and seventh day to establish the model of knee osteoarthritis and the same volume of saline was injected into the contralateral articular cavity as control. The activity scope of knee joint was measured in batches on the first, second, fourth week after the first injection and the rats were sacrificed and the knee joint cartilages were cut for general observation and histopathological examination. Results: The degenerative changes were demonstrated in the knee joints injected with papain and L-cysteine, such as the lower activity scope of knee joint, thinner and worse articular cartilage, fissuration, fibrous degeneration, fibrillation and destroyed cartilage matrix. All these changes were much worse with prolonged observation time. No similar changes were found in the control group, with significant difference between them. Conclusion: Pathological similarities between papain induced rats knee osteoarthritis and human knee osteoarthritis were observed. This animal model can be used for exploring pathogenesis of this disease and selection of treatments for osteoarthritis of knee joint.

Authors: GUO Xingming, XIE Meilan, WU Wenzhu, XIAO Zifu, YANG Yong, XIAO Shouzhong
PP: 2461~2465
Abstract: The goal of the study is to get an insight into college student cardiac responses to hypoxia conditions by studying first heart sound (S1) and second heart sound (S2) amplitude ratio (S1/S2) variability. A breath-holding phonocardiogram test (BHPCGT) was designed for inducing a hypoxia condition. When performing the BHPCGT in 116 subjects (71 athletes and 45 non-athletes), a phenomenon, reversal of S1/S2, was found in 13 samples (6 full-reversal and 7 partial-reversal). There were 4 (5.63%) reversed samples in athletes controlled with 9 (20%) in non-athletes. Paired t-test statistic results showed that 50 (70.42%) samples in athletes and 32 (71.11%) in non-athletes had significant differences (P<0.05) between the two conditions. It suggests that holding breathe does have influenced the function of heart to some extent, and the tolerance to hypoxia may be better in athletes than in non-athletes. The reversal of S1/S2 may have a significant value in assessing cardiac reserve, studying cardiac fatigue and observing heart responses to hypoxia.

Title: The functions of ISL1, a LIM-homeodomain transcription factor in cardiac development
Authors: LIU Yinan, WANG Weiping, LI Yanming, ZHOU Chunyan
PP: 2451~2456
Abstract: ISL1 is a member of LIM-Homeodomain transcription factor family. Recent studies show that ISL1 plays a pivotal role for the earliest stage of heart development. isl1 knockout in mice leads to a completely missing of the outflow tract, right ventricle, and much of the atria, ultimately results in the mice to die at embryonic day 10.5 (E10.5). Lineage tracing analysis demonstrates that ISL1 mainly marks cardiac progenitors derived from the second heart field. It is required for proliferation, migration and survival of these progenitors. Currently, ISL1-positive progenitors have been isolated from embryonic heart, postnatal heart, and even gene specific-targeting embryonic stem cells. These cells exhibited robust multiple differentiation potential, which not only differentiated into functional cadiomyocytes, but also differentiated into all the other diverse cardiac cell types. Therefore, ISL1-positive cells represent tissue-specific cardiac progenitors, and have significantly valuable therapeutic effects in myocardial regeneration and injury. This paper focuses on the research advances of ISL1 in cardiac development during recent years.
