Chinese Journal of Biochemical Pharmaceutics 2017;37(8):133-134
Objective To study the effect of different doses of dexmedetomidine combined with propofol and remifentanil in patients undergoing abdominal surgery. Methods 200 cases of abdominal operation in our hospital from January 2015 to August 2016 were selected as the subjects, and were randomly divided into the experimental group and the control group, with 100 patients in each group. Patients in the control group received 0.4μg/kg, dexmedetomidine hydrochloride injection combined with propofol and remifentanil anesthesia, and the experimental group received 0.8μg/kg, Dexmedetomidine Hydrochloride Injection anesthesia. The adverse reactions, extubation time and recovery time of the experimental group and the control group were compared and analyzed. Results After the corresponding dose of dexmedetomidine, the patients in the experimental group were 6 cases of nausea and vomiting, 7 patients with chills, 13 cases of adverse reactions, the total incidence was 13%. In the control group, shivering occurred in 23 cases, nausea and vomiting occurred in 12 patients, and the number of adverse reactions in 35 cases, the incidence of adverse reactions was 35%. The probability of adverse reactions in the control group was significantly higher than that in the control group, with statistical difference (P<0.05). The recovery time and extubation time of the experimental group were significantly lower than those of the control group, with statistical difference (P<0.05). Conclusion 0.8μg / kg dexmedetomidine hydrochloride Iinjection combined with propofol and remifentanil anesthesia in abdominal surgery is better anesthesia effect, can significantly shorten the time of patients with tube drawing, high safety, reduce the pain and risk of surgery patients has clinical significance in the further promotion and application.

Capital logic is the first to be avoided in the construction of medical humane service system,for it is capital logic that manifest the current technical and commercialized time with an "indifferent" characteristic.Capital logic originated and distended from the western culture.As another spiritual pursuit and wisdom,traditional Chinese philosophy provides us with significant ideological resources and helpful revelation for improving medical humane service in current circumstances.

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 .

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.

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.
