Chinese Traditional and Herbal Drugs 2013;44(22):3177-3181
Objective: To explore the difference of hot and cold property of Coptidis Rhizoma (CR) before and after being processed with ginger juice. Methods: To feed rats for 29 d with the decoction of un-processed CR (UPCR) and ginger juice-processed CR (GPCR), the rats' blood was collected at different administration time, the data by HPLC-MS/MS analysis were processed with PCA to determine the metabolites difference between the treatment groups. Results: On the day 29, the metabolic status of endogenous substances in rats' blood showed the biggest difference between the UPCR and GPCR groups. Through checking the endogenous biomarkers of the rats in each group, the content of markers related to amino acid energy metabolism of rats in the GPCR group was higher than that in the UPCR group, indicating the energy metabolism of the GPCR was stronger than that of the UPCR, which showed the differences in cold and hot property between the two drugs. Conclusion: The results show that the differences in potency of the UPCR and GPCR can be reflected by rats' different biological effects. The results are consistent with the traditional processing theory in Chinese materia medica that the cold property of CR could be moderated to be colder by processing with assistant materials with hot property (ginger juice). The work indicates that the metabonomic method is a valuable tool in the research of processing effect on properties of Chinese medicinal substances. The results are helpful to clarify the mechanism of processing CR with ginger juice in the future.

OBJECTIVETo clarity the original plants and the main application varieties of White Flos Gentianae.
METHODHerbal textual research, wild specimen collection, investigation and collection of the samples from Tibetan hospital, Tibetan pharmaceutical factory and medical material market were carried out simultaneously to identify the original plants of White Flos Gentianae.
RESULTThe results of varieties textual research and specimen identification showed that Gentiana szechenyii, G. purdomii and G. algida were in accord with the record of Tibetan herbal textual The three species above were the original plants of White Flos Gentianae. The identification of 20 batches samples showed that G. szechenyii was the main application variety. The other varieties were only used in Tibetan hospitals. All the samples above were flowering branches.
CONCLUSIONIt was necessary to strengthen the research on variety systematization of White Flos Gentianae make a further discussion on the taxonomy position of G. purdomii, G. algida and the white flos population. Its was also nessary to establish and improve the quality standard of different variety based on the principle of "one species, one name". The quality specification of White Flos Gentianae should be established and improved to standard clinical utilization and produce feeding. More study of resources investigation and cultivation of G. szechenyii should be carried on to meet the demand of produce and clinic.

6.Current researching situation of mucosal irritant compontents in Araceae family plants.
China Journal of Chinese Materia Medica 2006;31(18):1561-1563
Plants in Acaceae family are often considered as ornamental and medicines. However many of them have irritation properties. As medicinal plants some of them are recorded in Chinese Pharmacopoeia and they are figured as poisonous. Through investigating the domestic and overseas studied paper, the needle-like calcium oxalate crystal exits in the plants of Acaceae family could be thought as irritation components of them. This conclusion is same with the studied conclusion of our study group in the medicines plant of Pinellia ternate belonging to the Acaceae family and our studies showed that the needle-like calcium oxalate crystal was the main irritation component of raw P. ternate. The irritated mechanism of raphides is relevant to its special shape, the protein enzyme adhering to it and idioblasts in plants.

7.Study on irritation of calcium oxalate crystal in Araceae plants.
China Journal of Chinese Materia Medica 2008;33(4):380-384
OBJECTIVETo validate the irritation effects of calcium oxalate crystal in several herbal drugs which come from Araceae plants.
METHODCompared the irritation of pure calcium oxalate crystals isolated from the raw rhizome of Typhonium flagelliforme, T. giganteum and Arisaema erubescens and studied the quantity and irritating effect relationship of different concentration suspensions of needle-like calcium oxalate crystals by using the model of rabbits' eyes.
RESULTCalcium oxalate crystals isolated from above three rau rhizome typhonium rhizome showed strong irritation effects on rabbits' eyes. Under the condition of same content of calcium oxalate crystals, there were no difference in irritation effect between the suspensions of raw medicinal materials and pure calcium oxalate crystals. The degree of irritation on rabbits' eyes showed undoubted quantity and irritating effect relationship with the concentrations of Calcium oxalate crystel.
CONCLUSIONCalcium oxalate crystal is the irritant component in some herbal drugs which come from Araceae plants.

Objective To investigate the relationship between cardiac vagus nerves and changes of connexins(Cx)and intracellular gap junction(GJ)distribution pattern in superior vena cava(SVC)myosleeve in dog with atrial fibrillation(AF).Methods Twenty four hybrid dogs were divided into sham operation group(Sham group,n=8),SVC-AO fat pad removed group(RM group,n=8)and SVC-AO fat pad reserved group(RS group,n=8).In RM group and RS group,right atrial pacing was performed at a frequency of 500~650/min for 6 weeks to establish AF model.AF was induced by programmed stimulation or burst stimulation of atrial pacing.The expression and distribution of Cx40 and Cx43 in the SVC myosleeve tissue in three groups were analyzed by immunofluorescence staining.Transmission electron microscopy was used to observe the uhrastructural organization of gap junction(GJ).Results The rate of inducing sustained AF(> 15 min)in RS group was significantly higher than that in RM group (P < 0.01).The expression of Cx40 and Cx43 in the SVC myosleeve in sham group and RS group were significantly higher than that in RM group(P < 0.05).Furthermore,the expression of Cx40 and Cx43 in RS group were obviously higher than that in sham group(P <0.05).The ratio of end-to-end to side-to-side in RS group was lower than that in Sham group and RM group.Comparing with RM group,the channel of GJ became shorter and wider in RS group(P <0.05).Sarcomere was dissolved and mitochondrion showed vacuole degeneration in RS group.Conclusion The remodeling of Cx40 and Gx43 in SVC myosleeve tissue may be mediated by vagus nerves.It is conducive to the maintenance and stability of AF.However,this effect can be weakened by removing SVC-AO fat pad of canine.

Objective To investigate the effects of enteral nutrition with galactooligosaccharides (GOS) on serum inflammatory cytokines in rats with severe acute pancreatitis (SAP). Methods SD rats were randomly divided into sham operation control group, SAP with enteral nutrition (EN) group and SAP with EN supplemented with GOS (GOS-EN) group, and each group was divided into 4 d and 7 d subgroups according to the time that animals were sacrificed (n=8 in each subgroup). Rat SAP models were established by injection of 38 g/L sodium taurocholate beneath the pancreatic capsule. The serum amylase, inflammatory cytokines TNF-α, IL-2 and IL-10 were detected. Results At each time point, the levels of serum amylase in all SAP groups were significantly higher than those in sham operation control group (P < 0.01), and the levels in GOS-EN group were significantly lower than those in EN group (P < 0.01). The levels of serum TNF-α and IL-10 in all SAP groups were significantly higher than those in sham operation control group (P < 0.01), while the levels of IL-2 in all SAP groups were significantly lower than those in sham operation control group. The levels of TNF-α in GOS-EN group were significantly lower than those in EN group (P <0.05), while the levels of IL-2 and IL-10 and the ratio of IL-10/TNF-α were significantly higher than those in GOS-EN group (P < 0.05). Conclusion Early EN supplemented with GOS could modulate the balance of pro- and anti-inflammatory response.
