Family Schisandraceae is composed of two genera Schisandra and Kadsura, which are quite different in regard to the used part and medical function. Traditionally, the fruits of Schisandra plants were called 'Wuweizi' used as tonic for neurasthenia, antitussive, and sedative agents. The stems and roots of Kadsura plants, with names related to 'XueTeng', possess activating blood circulation and eliminating stasis and are used for the treatment of rheumatism, fractures and irregular menstruation. The dried fruit of Schisandra chinensis was recorded in Chinese Pharmacopoeia (2010 Edition) as 'Wuweizi', while the dried fruit of S. sphenanthera was recorded as an official origin of 'Nanwuweizi'. Historically, there was no evidence that the fruits of Kadsura plants were substituted as 'Wuweizi' either in ancient literatures or contemporary marketing. However, genus Kadsura is still popularly called 'Nanwuweizi' and plant K. longipedunculata is regarded as the origin of 'Nanwuweizi', thus this will cause confusion as well as misunderstanding of genus Kadsura. The authors recommended, therefore, the Chinese name of genus Kadsura should be 'Lengfantengshu' and K. longipedunculata with the name of 'Lengfanteng' in order to guarantee the drug authenticity.

Objective: To prepare the ethosomes-based gel of demethylzeylasteral (DMZ) and to investigate its properties and transdermal absorption behavior. Methods: The infusion method was used to prepare DMZ ethosomes. The particle size, entrapment efficiency (EE), analysis methodology, and in vitro release behavior were examined, respectively. The in vitro transdermal absorption of ethosomes-based gel of DMZ was evaluated by Franz diffusion cells. Results: The DMZ ethosomes was yellowish emulsion. The average particle size of the ethosomes was (365.2 ± 14.4) nm and the EE was (72.30 ± 2.31)%. The cumulative permeation curve of DMZ in ethosomes-based gel was consistent with Higuchi equation (Q=80.198 t1/2-71.641, r=0.986 8). Compared with common gel, the ethosomes-based gel had 3.94 times higher cumulative permeation amount in 24 h. Conclusion: The prepared ethosomes- based gel of DMZ could enhance the transdermal permeation, which provides evidence for the development of transdermal drug delivery system of DMZ.

Vibrio parahaemolyticus has been considered as one of the most important foodborne bacterial pathogens.The loop-mediated isothermal amplification(LAMP) that amplifies DNA with high specificity and rapidity under an isothermal condition was applied for rapid detection of this pathogen for the first time.A set of four primers,two outer and two inner primers,was designed specifically to recognize the thermolabile hemolysin gene(tlh) of V.parahaemolyticus.The LAMP reaction mix was optimized.The most optimal reaction temperature and time of the LAMP assay for the tlh gene were 60℃ and 60min,respectively.Genomic DNAs from 28 bacterial strains including 14 V.parahaemolyticus strains were amplified using LAMP,and no amplicon was observed in other bacterial strains.The detection limit of this LAMP assay was around 90 fg of V.parahaemolyticus genomic DNA and 24 colonies forming units for pure cultures.In addition,this method was applied to detect artificially contaminated food samples,and the detection limit was 89 cfu/g for non-cultured artificially contaminated food samples.These results suggested that detection of V.parahaemolyticus by LAMP is an effective and low-cost procedure with high specificity and sensitivity that requires no specialized equipment.This assay is expected to become a valuable tool for rapid detection and identification of V.parahaemolyticus.

OBJECTIVETo analyze the effect of Chinese herbs used by Prof. LI Tao on peripheral blood T subsets in treating multiple sclerosis (MS) by using association rules and statistical methods, thereby providing evidence for optimizing prescriptions.

METHODSData of MS inpatients and outpatients recorded by data collecting system, Xiyuan Hospital, China Academy of Chinese Medical Sciences were resorted. The relationship between Chinese herbs and T cell subsets were analyzed using SPSS17.0 and Aprior module in SPSS Clementine 12.0.

RESULTSRadix bupleuri, Radix Paeoniae alba, Fructus Aurantii, Atractylodes, and Radix Glycyrrhizae were most commonly used herbal combinations.Radix Aconiti lateralis preparata and Rhizoma Smilacis glabrae were often added. Radix Aconiti lateralis preparata was associated with decreased Th1 cells (confidence level 83.78%, supportive level 36.26%). Decreased Th1 cell was associated with Radix Aconiti lateralis preparata (confidence level 71.26%, supportive level 36.26%).Radix Aconiti lateralis preparata was obviously associated with decreased Th1 cells. Radix Bupleuri, Radix Paeoniae alba, bitter orange, Atractylodes , Radix glycyrrhizae, and Radix Aconiti lateralis preparata could reduce peripheral blood Th1 subsets of MS patients and elevate Th2 subsets (all P < 0.01).

CONCLUSIONSThe herbal combination of Radix Bupleuri, Radix Paeoniae alba, Fructus Aurantii, Atractylodes, Radix Glycyrrhizae, Rhizoma Smilacis glabrae, and Radix Aconiti lateralis preparata could lower peripheral blood Th1 cells and elevate Th2 cells, and prevent the relapse of MS possibly by reducing Th1 cells and elevating Th2 cells. Especially Radix Aconiti lateralis preparata played important roles in aforesaid changes of Th1 and Th2.

OBJECTIVETo study the effect of Qinghuang Powder (QHP) combined Chinese herbs for Pi-strengthening and Shen-reinforcing (CHPSSR) on hypoxia-inducible factor 1alpha (HIF-1alpha) in bone marrow mononuclear cells of myelodysplastic syndrome (MDS) patients.

METHODSChanges of HIF-1alpha in bone marrow mononuclear cells of MDS patients were detected in 25 MDS patients treated by QHP combined CHPSSR using flow cytometry. Meanwhile, 13 healthy subjects were recruited as the control group. Changes HIF-1alpha levels in various serial bone marrow mononuclear cells were detected.

RESULTS(1) Among the 25 patients in the treatment group, there were 19 patients effective and 6 patients ineffective, with the total effective rate being 76%. (2) Compared with before treatment, levels of peripheral blood WBC, Hb, PLT, and ANC significantly increased in the treatment group after treatment, showing statistical difference (P < 0.05, P < 0.01). (3) Compared with before treatment, the HIF-1alpha mean fluorescence intensity was enhanced in bone marrow lymphocytes, monocytes, granulocytes, and nucleated red blood cells of the treatment group after treatment (P < 0.05, P < 0.01). Compared with the control group, the HIF-1alpha mean fluorescence intensity was weakened in bone marrow lymphocytes, monocytes, and nucleated red blood cells of the treatment group before treatment; while it was obviously enhanced in granulocytes (P < 0.01). But after treatment the HIF-1alpha mean fluorescence intensity increased more in the granulocytes of the treatment group than in those of the control group (P < 0.01), but there was no statistical difference in bone marrow lymphocytes, monocytes, or nucleated red blood cells.

CONCLUSIONQHP combined CHPSSR could improve HIF-1alpha levels in bone marrow lymphocytes, monocytes, granulocytes, and nucleated red blood cells of MDS patients, thus improving Hb levels of MDS patients, and improving their anemia and correlated symptoms.
