BACKGROUND:According to the theory of Traditional Chinese Medicine, stimulating certain acupoints of the body after exercise may improve its antioxidant capacity, but different acupoints have different effects. OBJECTIVE:To compare the effect of different acupuncture combinations on the antioxidant capacity of myocardial and liver tissues in rats after exhausted swimming exercise, and screen out the optimal acupoint combination for exercise-induced fatigue. METHODS:Seventy Sprague-Dawley male rats were divided into five groups: control group (n=10), model group (n=15),Sanyinjiao +Zusanli group (n=15),Shenshu +Zusanli group (n=15),Dazhui+Zusanli group (n=15). Except the control group, rats in the other four groups were subject to exhausted swimming. In the three acupuncture groups, rats were given acupuncture at corresponding acupint combinations at 15 minutes after exercise. RESULTS AND CONCLUSION:Compared with the control group, the activities of superoxide dismutase and glutathione peroxidase in the myocardial and liver tissues were significantly reduced in the model group, while the malonaldehyde content in cardiac muscle was significantly increased. Compared with the model group, the activities of superoxide dismutase and glutathione peroxidase in the cardiac muscle were significantly increased inSanyinjiao +Zusanli group, the superoxide dismutase in liver tissue was significantly increased inShenshu+Zusanli group, the malonaldehyde content in the myocardial tissue was significantly decreased in Sanyinjiao +Zusanli group and Dazhui +Zusanligroup, the malonaldehyde content in the liver tissue was significantly decreased in Sanyinjiao +Zusanligroup. Different acupuncture combinations have different effects on the activities of superoxide dismutase and glutathione peroxidase, as wel as the malonaldehyde content in the myocardial and liver tissues of fatigued rats. Acupunture could increase the antioxidant ability in cardiac muscle of rats and the best combination might beDazhui+Zusanli; acupoint combinations ofShenshu +Zusanli andSanyinjiao +Zusanli are specific for liver tissue.

Objective·To observe changes of exhaled nitric oxide (FeNO) level in patients with chronic obstructive pulmonary disease (COPD) before and after inhaled corticosteroid (ICS) therapy and to explore the correlation of FeNO level with inflammation and pulmonary function indexes. Methods·Seventy COPD patients at stable stage who underwent ICS therapy (the COPD group) were enrolled. Levels of peripheral blood eosinophil (Eos) and neutrophil (N), FeNO, PEF, FEV1 and FEV1/pred before and after treatment were measured. Fifty healthy volunteers who received physical examination at the same time served as controls (the control group). The relationship between these indexes and clinical efficacy and the correlation between FeNO level and inflammation or pulmonary function indexes were analyzed. Results·The COPD group had significantly higher FeNO, Eos, and N levels before treatment, significantly lower PEF, FEV1 and FEV1/pred after treatment (P<0.05), and remarkably better indexes after treatment (P<0.05) compared with the control group. Indexes of the effective group and the improved group were significantly better than that of the ineffective group after treatment. Results of correlation analysis showed that before treatment, the FeNO level was positively correlated with peripheral blood Eos and N levels (P<0.05) and negatively correlated with PEF, FEV1 and FEV1/pred (P<0.05). After treatment, the FeNO level was positively correlated with peripheral blood Eos and N levels (P<0.05) and the correlation of the FeNO level with PEF, FEV1 and FEV1/pred was not statistically significant (P>0.05). Conclusion·The FeNO level increased significantly in patients with COPD at stable stage and is a sensitive index of airway inflammation. Combined with lung function test, it's useful for evaluating the efficacy of ICS and guiding treatment.

Objective:To study the effect of sevoflurane inhalation anesthesia on stress reaction and kynurenic acid ( KYNA) level in serum of the patients with laparoscopic cholecystectomy .Methods:Totally 48 patients undergoing laparoscopic cholecystectomy were randomly divided into two groups.Group S(n=24) received sevoflurane inhalation and group V (n=24) received intravenous general anesthesia.The levels of norepinephrine (NE), epinephrine (E), cortisol (Cor), KYNA and neutrophil and the neutrophil/lympho-cyte ratio were measured at five time points, namely T1(before the anesthesia), T2 (just after the surgery) , T3(in the morning of the first day after the surgery ) , T4 ( in the morning of the second day after the surgery ) and T5 ( in the morning of the third day after the surgery).The correlation of Cor, NE, E and NLR with KYNA was studied as well.Results:The levels of Cor, NE and E at the three time points after the surgery (T2, T3 and T4) in group V were significantly higher than those before the surgery (T1) with statistically significant difference (P<0.05), while those in group S had no significant changes (P>0.05).And the levels of Cor, NE and E at the three time points after the surgery (T2, T3 and T4) in group S were markedly lower than those in group V at the same time point (P<0.05).After the surgery (T2, T3, T4 and T5), KYNA levels in group V were significantly decreased and NLR values in group V were significantly increased when compared with those of T 1.In group S, KYNA levels and NLR values after the surgery (T2, T3, T4 and T5) were markedly increased , which were higher than those in group V at the same time point with statistically significant difference (P<0.05).The correlation analysis indicated the level of KYNA displayed positive correlation with the levels of NLR , Cr, Z and E (P<0.05).Conclusion:Sevoflurane inhalation anesthesia can inhibit the increase of stress reaction and KYNA level in the patients with laparoscopic cholecystectomy , which may be related with its anti-in ammatory properties .

This study was aimed to evaluate the applicability of common Chinese word segmentation software used in the literature study of traditional Chinese medicine (TCM) text,in order to put forward ideas on developing specialized TCM text word segmentation software.By means of installing and operating Chinese word segmentation software,the text segmentation experiment was conducted on TCM text samples.Aspects,such Chinese word segmentation accuracy,speed,maneuverability,reliability,extendibility,portability and other characteristics,were compared among different Chinese word segmentation software.The results showed that there were differences on the accuracy,speed,maneuverability,reliability,extendibility,portability among different Chinese word segmentation software.It was difficult to achieve best performance on different aspects by single software.Through the comparison of different Chinese word segmentation software,the Pan-Gu Segment software showed the best performance on accuracy,with good maneuverability,and high word segmentation efficiency,which was the most suitable for word segmentation in TCM text.It was concluded that developing specialized TCM text segmentation software may be the best solution to meet the requirement of text segmentation in TCM literature study.Basic studies should be strengthened from aspects,such as the construction of standard TCM copus,the completion of TCM dictionary base,the introduction,optimization and innovation of word segmentation algorithm,as well as the development of word segmentation software for TCM text.
