OBJECTIVETo investigate the effects of Shadu Cao Mixture (SDCM, traditional Chinese medicine) on immune functions of immunosuppression mice.
METHODSFifty BALB/C mice were randomly divided into blank control group, model group, SDCM low-dose, middle-dose and high-dose group. Except the blank control group, other groups were intraperitoneal injected with cyclophosphamide (40 mg/kg) to establish immunosuppression mice model. The blank control group and model group received gavage administration with nonnal saline, while the other groups received gavage administration with different doses of SDCM (10, 20, 40 m/kg for 15 days) respectively. The number of leukocytes and serum levels of interleukin-2 (IL-2), tumor necrosis factor-α (TNF-α) and interferon-γ (IFN-γ) in peripheral blood, spleen index, and the function of NK cells were measured.
RESULTSCompared with the model group , SDCM increased the number of leukocytes and serum concentrations of IL-2, TNF-α and IFN-γ in peripheral blood and improved the spleen index and the function of NK cells significantly (P < 0.05-0.01).
CONCLUSIONSDCM could remarkably enhance the immune functions of immunosuppression mice induced by cyclophosphamide.

To explore the prevention effect of the joint combination of Yindanxinnaotong soft capsule (YDXNT) and exercise (swimming) on atherosclerotic rats. The method of 3 x 3 factorial design, including two factors (YDXNT and swimming) and three levels (0, 1, 2 g x kg(-1) YDXNT; 0, 0.5, 1 h swimming), was mainly adopted. The atherosclerotic rat model was established by ligating their left common carotid arteries and feeding high-fat diet. After 8 weeks, blood samples were collected from their thoracic aorta to determine blood viscosity, plasma viscosity, fibrinogen (FIB), nitric oxide (NO), 6-keto-PGF(1alpha) endothelin (ET) and thromboxane B2 (TXB2). The tissues of left common carotid arteries of the rats were collected to detect the positive expression of SM22alpha and determine the semi-quantitation through the immunohistochemical staining. The result showed that the combination of YDXNT and swimming can significantly decrease the plasma viscosity (F = 3.241, P = 0.017), the high and low shear blood viscosity (F = 6.444, P = 0.001; F = 3.002, P = 0.024) and FIB (F = 4.046, P = 0.005). The increased NO and 6-keto-PGF(1alpha) and the decreased ET and TXB2 indicated a significant interaction (P < 0.05). The swimming showed an obvious main effect in the expression of up-regulated protein SM22alpha (F = 8.088, P = 0.001). The study suggested that the combined administration of YDXNT and swimming could improve the hemorheological parameters of atherosclerotic rats, protect the vascular endothelium, inhibit the vascular remodeling in atherosclerosis and positively prevent the atherosclerosis.

Objective To develop an early-warning indicator system of brucellosis outbreak. Methods The methods of literature review and expert discussion were used to formulate the initiatory framework and indicators, and then Delphi method was used to filter indicators, discuss the boundary of indicators and determine the weighting coefficient. Results The average length of service provided by experts who engaged in prevention and control of brucellosis was (25.10 ± 8.80) years and the positive coefficient of the consultant experts of the two-round results were 95% and 68%, respectively. Kendall coefficients were 0.35, 0.54 and X2R value were 81.31 and 285.27, respectively and P value was all less than 0.01. Five first-level indicators(the host animal, high-risk groups,social environment, index case and the level of previous disease) and 13 secondary indicators were selected to develop the early-warning indicator system of brucellosis outbreak. The weight coefficients of the five first-level indicators were 0.21, 0.22, 0.17, 0.21 and 0.19, respectively. Conclusions The early-waming indicator system of brucellosis outbreak is initially established. We propose to develop the early-warning programs according to local conditions and the indicator system.

AIMTo study the effect of lidocaine-dodecanol binary eutectic system on the transdermal permeation of lidocaine.
METHODSBinary eutectic mixture of different proportions of lidocaine and dodecanol were prepared and the patch containing the binary eutectic mixture was developed. The solubilities of pure lidocaine and lidocaine from the binary eutectic system were determined in pH 7.9 phosphate buffer. The transdermal flux of lidocaine from the patches containing the binary eutectic system and pure lidocaine were measured using Franz-type single diffusion cell.
RESULTSThe melting point of the lidocaine-dodecanol binary eutectic system was markedly lower than that of pure lidocaine. The steady state transdermal flux of lidocaine from the patch of the binary eutectic system was six times as much as that of pure lidocaine patch.
CONCLUSIONThe lidocaine-dodecanol binary eutectic system could produce high thermodynamic activity of the drug and the high driving force for transdermal permeation of lidocaine.

OBJECTIVETo study the protected effect of Yindan Xinnaotong capsule (YDXNTC) and main components compatibility on myocardium ischemia/reperfusion injury.
METHODGlobal ischemia/reperfusion was adopted to induce myocardial ischemia/reperfusion injury (MIRI) in isolated rat heart. Sprague-Dawley (SD) rats were divided into control, model, YDXNTC, Ginkgo biloba extract (GBE) group, ethanol extract of Salvia miltiorrhiza (SM-E) group, aqueous extract of Salvia miltiorrhiza (SM-H) group, mixed compatibility of other components in YDXNTC (MC), GBE and SM-E compatibility (GSEC), GBE and SM-H compatibility (GSHC), and SM-E and SM-H compatibility (SEHC). During the experiment, electrocardiogram was recorded to observe cardiac arrest time, heart resuscitation time, regaining normal rhythm time, the incidence and duration of arrhythmias (VT/VF). At the end of reperfusion, hearts were arrested and homogenated to assay the activity of superoxide dismutase (SOD), and the content of malondialdehyde (MDA), lactate dehydrogenase (LDH), creatine kinase-MB (CK-MB), cardiac troponin I.
RESULT(1) YDXNTC, SM-E, SM-H and MC elevated cardiac arrest time, also reduced rebeating time, restoring normal rhythm time as well as the duration of arrhythmia, but no remarkable impact on VT/VF occurrence. GBE was effective for incidence of VT/VF, also achieved good effect on shortening rebeating time, restoring normal rhythm time and arrhythmia duration. Likewise, obviously reduced rebeating time, restoring normal rhythm time and arrhythmia duration, and evaluated cardiac arrest time were also exhibited in compatibility groups except that no lengthened cardiac arrest time was detected in GSHC. And the incidence of VT/VF was decreased by GSEC. (2) YDXNT, ginkgo biloba extract (GBE), ethanol extract of salvia miltiorrhiza (SM-E), GBE and SM-E compatibility (GSEC), and SM-E and aqueous extract of salvia miltiorrhiza (SM-H) compatibility (SEHC) could improved SOD and decreased MDA level SM-H, mixed compatibility of other elements in YDXNTC (MC) and GBE and SM-H compatibility (GSHC) showed a role on MDA reduction. (3) LDH was declined by YDXNT and SM-H. CK-MB was reduced by GBE, SM-E, SM-H, and GSEC. (4) The release of cTnI was only inhibited by GSEC.
CONCLUSIONYDXNTC, primary materials and main components compatibility has a certain protection effect on MIRI, its mechanism may be related to antioxidant and calcium overload reduction.
