Objective To observe the influences of ether soaking method, solven t refluxing method and steam distilling method on the content and chemical compo nents of volatile oil from Lignum Santali. Methods Gas chromatograph_mass sp ectrogram (GC_MS) analysis was adopted. Results The content of santalol in t he oi l from Lignum Santali extracted by ether soaking was a little higher than that i n the volatile oil extracted by steam distilling, and their chemical components are similar. The total content of volatile oil extracted by solvent refluxing me thod was 3.35%, much higher than that by steam distilling metho d. GC_MS analysis showed the content of santalol and other chemical components a re similar by the two methods. Conclusion Ether soaking method can be used f or the qualitative analysis of volatile oil from Lignum Santali. Extraction of s antalum oil by steam distilling method is incomplete.

Objective To study the effects of two fungal elicitors on the growth of Dendrobium candidum protocorms cultured on the solid medium.Methods The medium for propagation of protocorms was selected and the growth curve on that medium was obtained.According to the curve,the two fungal elicitors were added at the different growth stages of protocorms.The fresh weight(FW) and dry weight(DW) of protocorms were measured.Results The medium for propagation of protocorms was 1/2MS+20% potato extract+3% sucrose+0.8% agar.Compared with the control MF23 elicitor added at weeks 11 and 13 could significantly increase the FW by 16.4%(P

Objective To discuss the modern surgical treatments for congenital choledochal cysts complicated with anomalous junction of pancreaticobiliary ductal system through analyzing data in 30 cases. Methods The 30 cases were diagnosed with ERCP, MRCP, cholangiography or dissection, respectively. Then 28 of them were treated with external drainage (n=2), internal drainage (n=9) and Roux-en-Y hepaticojejunostomy (n=22), respectively. Of the 28, 5 received operations twice. Results External drainage was helpful in emergency cases while internal drainage frequently resulted in recurrent cholangitis, choledocholith, anastomotic stenosis or cyst malignancy that needed to be operated on again. Choledochocyst resection and pancreaticobiliary shunt achieved satisfactory results. Conclusions Congenital choledochal cyst is usually complicated with anomalous junction of pancreaticobiliary ductal system (88.2%). As for its treatment, choledochocyst resection, pancreaticobiliary shunt and hepaticojejunostomy should be of the first choice.

Objective To investigate the effect of lipid emulsion on mitochondrial energy metabolism during bupivacaine-induced myocardiotoxicity in rats.Methods H9c2 cells were inoculated in 96-well plates at a density of 1 × 105cells/ml, and were randomly divided into 4 groups (n =18 each) using a random number table: control group (group C) , bupivacaine group (group B) , lipid emulsion group (group LE) , and bupivacaine + lipid emulsion group (group B + LE).The cells were incubated in the normal culture medium in group C.In group LE, the cells were incubated in the culture medium containing 1％ lipid emulsion.In group B, the cells were incubated in the culture medium containing 1 mmol/L bupivacaine.In group B + LE, the cells were incubated in the culture medium containing 1 mmol/L bupivacaine and 1％ lipid emulsion.After 24 h of incubation, the contents of ATP, ADP, and AMP were measured by high-performance liquid chromatography, and apoptotic rate was calculated by Hoechst33342/ PI staining.Results Compared with group C, the contents of ATP, ADP and AMP were significantly decreased, and apoptotic rate was increased in group B (P＜0.05), and the contents of ATP and ADP in group LE and ATP content in group B + LE were increased, and no significant changes were found in apoptotic rate in LE and B+LE groups (P＞0.05).Compared with group C, the contents of ATP, ADP and AMP were significantly increased, and apoptotic rate was decreased in LE and B+LE groups (P＜ 0.05).Compared with group LE, the contents of ATP, ADP and AMP were significantly decreased (P＜ 0.05), and no significant change was found in apoptotic rate in group B+LE (P＞0.05).Conclusion The mechanism by which lipid emulsion reduces bupivacaine-induced myocardiotoxicity may be associated with improved mitochondrial energy metabolism in rats.

Objective To evaluate the effect of mitochondrial permeability transition pore (mPTP) in lipid emulsion-induced inversion of bupivacaine myocardiotoxicity in rats.Methods H9c2 cells were inoculated in 6-well plates at a density of 105 cells/ml, and were randomly divided into 4 groups (6 wells in each group, 2 ml/well) using a random number table: control group (group C) , bupivacaine group (group B) , lipid emusion + bupivacaine group (group LB) , and lipid emusion + bupivacaine + atractyloside group (group LBA).Phosphate buffer solution 100 μl was added to the culture medium in group C.In group B, bupivacaine was added to the culture medium with the final concentration of 1 mmol/L.In group LB, lipid emusion and bupivacaine were added to the culture medium with the final concentrations of 1％ and 1 mmol/L, respectively.In group LBA, lipid emusion, bupivacaine and atractyloside (an mPTP opener) were added to the culture medium with the final concentrations of 1％, 1 mmol/L and 30 μmol/L, respectively.All the cells were incubated for 24 h.After the end of incubation, the expression of Bcl-2, Bax, phosphorylated Bad (p-Bad) , caspase-3, activated caspase-3, caspase-9,activated caspase-9 and cytochrome c (Cyt c) was detected using Western blot.The expression of Bcl-2 mRNA, Bax mRNA, Bad mRNA, caspase-9 mRNA and Cyt c mRNA was detected using real-time reverse transcriptase polymerase chain reaction.The ratios of Bax/Bcl-2, activated caspase-3/caspase-3, activated caspase-9/caspase-9, and Bax mRNA/Bcl-2 mRNA were calculated.Results Compared with group C,the ratios of Bax/Bcl-2, activated caspase-3/caspase-3, activated caspase-9/caspase-9, and Bax mRNA/ Bcl-2 mRNA were significantly increased, the expression of p-Bad was down-regulated, and the expression of Cyt c, Bad mRNA, caspase-9 mRNA and Cyt c mRNA was up-regulated in group B (P＜0.05) , and no significant change was found in the parameters mentioned above in group LB (P＞0.05).Compared with group B, the ratios of Bax/Bcl-2, activated caspase-3/caspase-3, activated caspase-9/caspase-9, and Bax mRNA/Bcl-2 mRNA were significantly decreased, the expression of p-Bad was up-regulated, and the expression of Cyt c, Bad mRNA, caspase-9 mRNA and Cyt c mRNA was down-regulated in LB and LBA groups (P＜ 0.05).Compared with group LB, the ratios of Bax/Bcl-2, activated caspase-3/caspase-3, activated caspase-9/caspase-9, and Bax mRNA/Bcl-2 mRNA were significantly increased, the expression of p-Bad was down-regulated, and the expression of Cyt c, Bad mRNA, caspase-9 mRNA and Cyt c mRNA was up-regulated in group LBA (P ＜ 0.05).Conclusion The mechanism underlying lipid emulsioninduced inversion of bupivacaine myocardiotoxicity is related to inhibited mPTP opening in rats.
