Objective To evaluate the effect of dexmedetomidine on myocardial injury in pediatric patients undergoing living-related liver transplantation. Methods Fifty-eight pediatric patients of both sexes,aged 5-20 months,weighing 4.5-15.0kg,of American Society of Anesthesiologists physical status Ⅲ or Ⅳ,scheduled for elective living-related liver transplantation,were divided into 2 groups(n=29 each)using a random number table:control group(group C)and dexmedetomidine group(group D).In group D,dexmedetomidine was intravenously infused at a dose of 0.5 μg/kg over 10min starting from the time point immediately before skin incision,followed by an infusion of 0.8 μg·kg-1·h-1 until the end of surgery. The equal volume of normal saline was given instead in group C. Immediately before skin incision(baseline,T0),at 10min of anhepatic phase(T1),at 30min of neohepatic phase(T2)and at the end of surgery(T3),blood samples were obtained from the central vein for determination of serum cardiac troponin I(cTnI),lactate dehydrogenase(LDH),alpha-hydroxybutyrate dehydrogenase(α-HBDH),interleukin-6(IL-6)and IL-10 concentrations. The changing rate of serum cTnI concentrations were calculated at T2. The occurrence of myocardial ischemia and ventricular premature beat and requirement for dopamine were recorded during surgery. Results Compared with the baseline at T0,the serum concentrations of cTnI,LDH and α-HBDH were significantly increased at T2,3,and the serum concentrations of IL-6 and IL-10 were increased at T1-3 in both groups(P<0.05).Compared with group C,the serum concentrations of cTnI,LDH,α-HBDH and IL-6 were significantly decreased at T2,3,the serum concentration of IL-10 was increased at T1-3,the changing rate of serum cTnI concentrations was decreased(P<0.05),and no significant change was found in the incidence of myocardial ischemia and ventricular premature beat and requirement for dopamine in group D(P>0.05).Conclusion Dexmedetomidine can attenuate the myocardial injury to some extent in pediatric patients undergoing living-related liver transplantation.

We present that the modern basic theory of traditional Chinese medicine is a new science in this article. To demonstrate the problem new discipline faced and needed to be understood, firstly we want to clear the related concepts of discipline and traditional Chinese medicine from an international perspective achieving the original inten-tion of deepening the research field, forming a discipline branch and towards modern teaching. Secondly, we explore the discipline classification system and in which the location of traditional Chinese medicine and theory of traditional Chinese medicine discipline, and then explore the discipline overall regularity of occurrence, development and demise focusing on regularity and evaluation criteria reveal of medicine and traditional Chinese medicine disciplines. On this basis, we demonstrate the discipline property and location of new scientific disciplines of modern basic theo-ry of traditional Chinese medicine, subjects and fields, direction and meaning and then draw a credible conclusion in accordance with deductive reasoning.

Natural products are important sources for the discovery of anti-tumor drugs. Evodiamine is the main alkaloid component of the traditional Chinese herb Wu-Chu-Yu, and it has weak antitumor activity. In recent years, a number of highly active antitumor candidates have been discovered with a significant progress. This article reviews the research progress of evodiamine-based antitumor drug design strategies, in order to provide reference for the development of new drugs with natural products as leads.

OBJECTIVETo study the effect of chronic occupational stress on the glucocorticoid receptor (GR) and immune function.

METHODSA cross-sectional study was conducted in 112 railway station dispatchers. Perceived job stress was assessed by means of the Chinese version of the Job Content Questionnaire. The subjects were divided into high, medium and low strain groups according to the job strain score of the questionnaire. The number of GR, percentage of T lymphocyte subpopulations, concentrations of cortisol and interleukin 2 (IL-2) in blood were measured.

RESULTSThe concentrations of serum cortisol in high and medium strain groups [(295.43 +/- 79.06) and (274.34 +/- 70.08) ng/ml respectively] were higher than that in low strain group [(181.01 +/- 53.41) ng/ml, P < 0.05]. GR binding capacity in both groups (4,330.0 +/- 1,001.0, 3,971.6 +/- 966.8 specific binding/cell respectively) were smaller than that in low strain group (5,141.3 +/- 1,068.5 specific binding/cell, P < 0.05). The percentage of CD(3) T lymphocyte in high strain group was higher than that in low strain group [(50.21 +/- 10.30)% vs (56.87 +/- 15.36)%, P < 0.05], and CD(4) T lymphocyte in high and medium strain groups were significantly smaller than that in low strain group [(23.27 +/- 10.01)%, (27.06 +/- 7.47)% vs (33.31 +/- 7.77)%, P < 0.05]. In contrast, the percentage of CD(8) T lymphocytes in high and medium strain groups were significantly higher than that in low strain group [(28.16 +/- 6.47)%, (25.54 +/- 6.70)% vs (21.91 +/- 5.93)%, P < 0.05]. The levels of serum IL-2 in high and medium groups were smaller than that in low strain group [(0.77 +/- 0.05), (0.80 +/- 0.07) vs (1.05 +/- 0.12) ng/ml, P < 0.05]. Correlation analysis showed that serum cortisol level was negatively correlated with CD(8) percentage (r = -0.612, P < 0.01).

CONCLUSIONChronic occupational stress may induce rise of glucocorticoid, down-regulation of GR and inhibition on immune function.

OBJECTIVETo investigate extracellular splitting pattern of mitochondria and the depressant effects of CsA on the process and explore the mechanism of post-traumatic SIRS and its therapeutic strategy.

METHODSTen male SD rats with 60 to 70 days age and 240 to 280 g weight were used for mitochondrial isolation. Freshly isolated mitochondria were randomly divided into two groups, which were cultured in blood plasma with or without CsA respectively for 8 h. COX and MDH were assayed by ELISA every 30 min. Meanwhile, Rat macrophage cell line NR8383 were treated as follows, control (group A): cultivation with normal medium; NR8383+CsA co-culture group (group B): culture medium was supplemented with CsA of 10 mmol/L; NR8383+intact mitochondria co-culture group (group C): culture medium was supplemented with intact mitochondria (mtDNA=5 g/ml); NR8383+intact mitochondria+CsA co-culture group (group D): culture medium was supplemented with intact mitochondria (mtDNA=5 μg/ml)and CsA of 10 mmol/L; NR8383+disrupted mitochondria co-culture group (group E): culture medium was supplemented with disrupted mitochondria (mtDNA=5 μg/ml); NR8383+disrupted mitochondria+CsA co-culture group (group F): culture medium was supplemented with disrupted mitochondria (mtDNA=5 μg/ml)and CsA of 10 mmol/L. TNF-α and IL-6 concentrations in supernatant were assessed at 1, 3, 5 h after culture.

RESULTSIn the mitochondria plasma cultures, MDH and COX levels were increased with the time and peaked at about 3 h and 3.5 h; CsA can delay the appearance of peak to 4.5 h. Among different treated groups,there was no significant difference in TNF-α and IL-6 between group A and group B; there was significant difference in TNF-α and IL-6 other groups. After 1 h culture, compared with group C, no significant difference of TNF-α and IL-6 was observed in group D, while TNF-α and IL-6 were significant higher in group E; after 3 h culture, compared with group C, TNF-α and IL-6 were significantly lower in group D, while TNF-α and IL-6 were significantly higher in group E; after 5 h culture, compared with group C, TNF-α and IL-6 were significantly lower in group D, while no significant difference of TNF-α and IL-6 were observed in group E. At each time point, there was no significant difference in TNF-α and IL-6 between group F and group E.

CONCLUSIONMitochondria can split in serum with time, which will further activate macrophages. CsA has depressant effect to mitochondrial splitting on the process and will therefore inhibit the activation of macrophages.

OBJECTIVETo study the effects of combined use of total alkaloids (TA) of Uncaria rhynchophylla (UR) and Coryadlis ambailis migo (CAM) on cerebral ischemia/reperfusion injury in rats.

METHODSRat model of middle cerebral artery ischemia/reperfusion was established, the changes of neurological state was scored before and after treatment with the two kinds of TA, single or combined, and the changes of cerebral infarcted volume, cerebral water content, activities of NOS and SOD and content of MDA in rats' brain were estimated as well.

RESULTSAfter being treated with the combination of both TA, the average neurological score, cerebral infracted volume, cerebral water content, activity of NOS and content of MDA in the model rats significantly decreased, and the activity of SOD was significantly increased (all P < 0.05). The effect of combined use of the two TA was higher than that of use TA of UR or CAM alone (P <0.05). Moreover, the central nervous system inhibitory effect induced by combined TA was significantly weaker than that of UR.

CONCLUSIONCombined use of TA of UR and CAM may facilitate the protection against cerebral ischemia/reperfusion damage, the action mechanism might be relevant to reducing the lipid peroxidation injury of brain cells through inhibiting the NOS activity and increasing the SOD activity.
