Phytoremediation effectiveness and remediation costs are driving factors of this project. Full utilization of plant resources after their being used for phytoremediation is an unsolved problem. GC/MS technique was used to investigate the volatiles of the flowers from Elsholtzia argyi (PFE1: Purple Flower Elsholtzia) and their variation (WFE: White Flower Elsholtzia), naturally growing in Pb/Zn mined area, and Elsholtzia argyi (PFE2: Purple Flower Elsholtzia), naturally growing in Jiuxi uncontaminated agriculture soil. Seventeen compounds constituting 86.88% of total essential oils were identified in PFE1, with 2,6-octadienoic acid,3,7-dimethyl-methyl ester being the main constituent (63.30%). Sixteen compounds accounting for 95.32% of total essential oils were identified in WFE, with caryophyllene being the main component (55.02%). Compared to PFE1, PFE2 contains lower level of 2,6-octadienoic acid,3,7-dimethyl-methyl ester (31.76%), which is the main constituent in the total essential oils of PFE2. Caryophyllene is the main ingredient of flavor. Elsholtzia ketone was identified in all the three Elsholtzia plants. It can be concluded that the selected Elsholtzia argyi plants can be exploited on their versatile uses as fragrances and antiseptics due to the perfume ingredient and antibacterial components existing in their essential oils.

A solution with different Cu supply levels was cultured to investigate gama-aminobutyric acid (GABA) accumulation in Elsholtzia splendens, a native Chinese Cu-tolerant and accumulating plant species. Increasing Cu from 0.25 to 500 micromol/L significantly enhanced levels of GABA and histidine (His), but considerably decreased levels of aspartate (Asp) and glutamate (Glu) in the leaves. The leaf Asp level negatively correlated with leaf Cu level, while leaf GABA level positively correlated with leaf Cu level. The leaf Glu level negatively correlated with leaf GABA level in Elsholtzia splendens. The depletion of leaf Glu may be related to the enhanced synthesis of leaf GABA under Cu stress.

Cirrhosis with portal hypertension is a common disease which has a significant impact on the quality of patients' life. Esophagogastric devascularization (EGDV) has been demonstrated to be an effective method to treat portal hypertension, however certain complications are associated with it. The purpose of this study was to evaluate the effectiveness and clinical outcome of the selective EGDV (sEGDV) for the treatment of portal hypertension. The study was conducted prospectively from Jan. 1 2011 to Dec. 31, 2012, and 180 patients were randomized to the sEGDV group (n=90) or the non-sEGDV (n-sEGDV) group (n=90). Patients' demographics, preoperative lab test results and operative details were comparable between the two groups. Postoperative and short-term complications were analyzed in two groups. There was statistically significant difference (P<0.01) in the PVF reduction between the two groups. Post-operative complications showed no statistically significant difference between the two groups in the incidence of bleeding, ascites, acute portal vein thrombosis, fever and hepatic encephalopathy. Mortality between two groups was comparable. The incidence of splenic fossa effusion after the surgery was lower in sEGDV group than in n-sEGDV group. There were no significant differences in the short-term follow-up data such as esophageal varices and portal hypertensive gastropathy (P>0.05). It is suggested that sEGDV is a safe, simple and effective surgical procedure. It has both the advantages of the shunt and devascularization because it preserves body's voluntary diversion. With the advantage of low incidence of postoperative complications, it is an ideal surgical approach for the treatment of portal hypertension.

Clove oil and turmeric oil were absorbed by mesoporous carbon. The absorption ratio of mesoporous carbon to volatile oil was optimized with the eugenol yield and curcumol yield as criteria Curing powder was characterized by scanning electron microscopy (SEM) and differential scanning calorietry (DSC). The effects of mesoporous carbon on dissolution in vitro and thermal stability of active components were studied. They reached high adsorption rate when the absorption ratio of mesoporous carbon to volatile oil was 1:1. When volatile oil was absorbed, dissolution rate of active components had a little improvement and their thermal stability improved after volatile oil was absorbed by the loss rate decreasing more than 50%. Absorbing herbal volatile oil with mesoporous carbon deserves further studying.

OBJECTIVETo investigate whether the cardioprotective effect of hemin against ischemia/reperfusion (I/R) injury is through the inhibition of calpain activity, and to explore its underlying mechanism.

METHODSSixty-four SD rats were randomly divided into eight groups (n = 8): sham, I/R, MDL+ I/R, MDL, hemin + I/R, hemin, and ZnPP + hemin+ I/R, ZnPP. Iangendorff isolated rat heart perfusion model was used. The rat hearts were suffered from 40 min of ischemia followed by 30 min of reperfusion. After that, left ventricular developed pressure (LVDP) was recorded. Infarct size and release of lactate dehydrogenase (LDH) were measured. Calpain, heme oxygenase (HO), and caspase 3 activities were evaluated. Expression of calpastatin protein was detected by Western blot.

RESULTS(1) After suffered from ischemia/reperfusion, the calpain activity and caspase 3 activity increased. MDL28170, an inhibitor of calpain, prevented ischemia/reperfusion induced increases in LDH and infarct size, improved the LVDP recovery. (2) Compared with ischema/reperfusion rat hearts, pretreatment of hemin enhanced the HO-1 activity, decreased the calpain and caspase 3 activities, declined LDH release and infarct size, and improved LVDP recovery. (3) Ischemia/reperfusion reduced the expression of calpastatin protein in rat hearts, which was inhibited by hemin pretreatment. And HO-1 inhibitor could abolish the cardioprotection of hemin.

CONCLUSIONCardioprotective effect of hemin against ischemia/reperfusion injury is through the inhibition of calpain activity, the mechanism might be involved in the increase in calpastatin protein expression.
