Litsea cubeba is one of aromatic medicinal plant belonging to family Lauraceae. The roots, stems and fruits of L. cubeba have been widely applied as folk medicines in some districts in China for relieving rheumatism and cold, regulating Qi (meridian) to alleviate pain. Previous studies revealed that this species contains major alkaloids, in specific aporphines, and minor flavonoids, lignans as well. Related pharmacological investigations demonstrated its activities and clinical applications on cardiovascular diseases, anti-cancer, against rheumatoid arthritis, relieving asthma and anti-allergic effects, as anti-oxidants, and so on. As an effort for further exploration of this bioactive ingredients and potential drug development, this paper summarizes most phytochemical and pharmacological results. Further, future prospects are also included.

Objective: To evaluate the effectiveness of therapeutic massage (tuina) for treating knee osteoarthritis (KOA). Methods: Six English and Chinese databases, including Chinese National Knowledge Infrastructure (CNKI), Wanfang Academic Journal Full-text Database (Wanfang), Chongqing VIP Database (CQVIP), China Biology Medicine Disc (CBM), Cochrane Library and PubMed databases, were independently searched to identify appropriate randomized controlled trials (RCTs) studying therapeutic massage for KOA compared to oral non-steroidal anti-inflammatory drugs (NSAIDs) alone. The main outcome measures were total effectiveness and the Western Ontario and McMaster Universities osteoarthritis index (WOMAC) score. Results: A total of 8 RCTs were included and they were of average quality. The results showed that therapeutic massage was more effective than NSAIDs comparing total effectiveness [risk ratio (RR)=1.14, 95% confidence interval (CI) (1.07, 1.21), P<0.0001]; compared with NSAIDs, therapeutic massage produced more significant improvements in pain [mean difference (MD)=-2.06, 95%CI (-2.75, -1.36), P<0.00001], stiffness intensity [MD=-0.90, 95%CI (-1.05, -0.75), P<0.00001] and joint function [MD=-12.48, 95%CI (-13.91, -11.05), P<0.00001]. Conclusion: Therapeutic massage was more effective than oral NSAIDs in treating KOA. In relieving pain and stiffness and improving the function of knee joint, therapeutic massage was superior to NSAIDs.

Laser scanning confocal microscopy (LSCM) and whole-cell perforated patch-clamp techniques were combined to study simultaneously the changes of intracellular signal molecules and membrane currents. Intracellular calcium transients and spontaneous transient outward currents (STOCs) were recorded simultaneously in freshly isolated mouse cerebral artery smooth muscle cells. The cells loaded with fluo-4/AM were scanned with the confocal line-scan mode. Triggering voltage pulses derived from an EPC-10 patch clamp amplifier triggered the confocal line scan. The results showed that STOCs and intracellular calcium transients could be simultaneously recorded in the same cell. This technique will be useful in studies of diseases caused by impairments of intracellular Ca(2+) signaling and related ionic channel activities, or vice versa.

China Journal of Chinese Materia Medica 2006;31(4):269-279
In this article, the research of chemical constituents and bioactivities in recent ten years has been reviewed of plants from the 12 genera in Flacourtiaceae related to the medicinal resources in China. The research in China about the plants from Flacourtiaceae was done very little, but many literatures have been reported abroad. The plants from Flacourtiaceae mostly contain the constituents such as aromatic glucosides, lignanoid glucosides, diterpenoids and cyclopentenoid cyanohydrin glucosides et al. These compounds or plant extracts mainly show antibacterial, antiviral, antitumor, hypolipidemic and hypoglycemic activities. The research of plants from Carrierea, Itoa and Bennettiodendron of Flacourtiaceae in China is still blank. The systemic research about chemical constituents and bioactivities of plants from these genera will play important roles in the discovery of novel natural products and active constituents, and provide valuable reference for the classifying of plants from these genera.

It was estimated that about 428 species of genus Corydalis are distributed all worldwide, with about 298, especially 10 groups and 219 species being uniquely spread in China. The genus Corydalis have been widely employed as folk medicines in China, especially as traditional Tibetan medicines, for treatment of fever, hepatitis, edema, gastritis, cholecystitis, hypertension and other diseases. The phytochemical studies revealed that isoquinoline alkaloids are its major bioactive ingredients. The extensive biological researches suggested its pharmacological activities and clinic applications against cardiovascular diseases and central nervous system, antibacterial activities, analgesic effects, anti-inflammatory, anti-oxidation and anti-injury for hepatocyte, and so on. As an effort in promoting the research of pharmacodynamic ingredients, this article presents an overview focusing on the distribution, phytochemical and pharmacological results of Corydalis species that have been applied in traditional Tibetan medicinal, hopefully to provide a reference for the new Tibetan medicine development from Corydalis plant resource.

A phytochemical investigation on the aerial parts of a Tibetan medicine Meconopsis horridula, by solvent extraction, repeated chromatographies on silica gel, Sephadex LH-20, and preparative TLC techniques, led to the isolation of 9 compounds. By spectroscopic analysis and comparison of its 1H and 13C-NMR data with those in literatures, their structures were identified as oleracein E(1), N-( trans-p-coumaroyl) tyramine (2), chrysoeriol (3), apigenin (4), hydnocarpin (5), p-coumaric acid glucosyl ester (6), stigmast-5-ene-3beta-ylformate (7), 3beta-hydroxy-7alpha-ethoxy-24beta-ethylcholest-5-ene (8), and beta-sitosterol (9), respectively, among which compounds 6-8 were isolated from the genus for the first time,and 1,3 were isolated from the species for the first time. A MTT method was applied to evaluate the cytotoxic activity of compounds 14 against the human hepatocellular liver carcinoma cell line (HepG2), and compound 1 showed significant cytotoxicity against HepG2,with its inhibitory rate of 52.2% at 10 micromol x L(-1).

OBJECTIVETo establish discriminant functions of diarrhea-predominant irritable bowel syndrome (IBS-D) by studying it from quantitative diagnosis angle, hoping to reduce interference of subjective factors in diagnosing and differentially diagnosing Chinese medical syndromes of IBS-D.
METHODSA Chinese medical clinical epidemiological survey was carried out in 439 IBS-D patients using Clinical Information Collection Table of IBS. Initial syndromes were obtained by cluster analysis. They were analyzed using step-by-step discrimination by taking information of four Chinese medical diagnostic methods and serum brain-gut peptides (BGP) as variables.
RESULTSClustering results were Gan stagnation Pi deficiency syndrome (GSPDS), Pi-Wei weakness syndrome (PWWS), Gan stagnation qi stasis syndrome (GSQSS), Pi-Shen yang deficiency syndrome (PSYDS), Pi-Wei damp-heat syndrome (PWDHS), cold-damp disturbing Pi syndrome (CDDPS). Of them, GSPDS was mostly often seen with effective percentage of 34. 2%, while CDDPS was the least often seen with effective percentage of 5.5%. A total of 5 discriminant functions for GSPDS, PWWS, GSQSS, PSYDS, and PWDHS were obtained by step-by-step dis- crimination method. The retrospective misjudgment rate was 4.1% (16/390), while the cross-validation misjudgment rate was 15.4% (60/390).
CONCLUSIONThe establishment of discriminant functions is of value in objectively diagnosing and differentially diagnosing Chinese medical syndromes of IBS-D.
