Fruiting bodies(500 g per site) of Tricholoma matsutake and the surface layer of soils collected from 20 spatially distant areas with pristine backgrounds across China were analyzed for potassium,magnesium,calcium,zinc,iron,copper,manganese and cadmium using inductively coupled plasma optical emission *** terms of the bioconcentration and bioexclusion concept,K,Mg,Zn,and Cu were highly bioconcentrated,and their bioconcentration factor values varied between 75-615,2-107,38-603 and 7-76,respectively,across the 20 ***,Mn and Cd were moderately bioconcentrated and their bioconcentration factors(BCFs) varied between 0.6-34.0,0.4-37.0 and 0.9-7.0 ***,Ca was excluded(BCF<1).*** is a species that is harvested in the wild as a valuable food and can contain a wide spectrum of both essential and hazardous mineral compounds that accumulate at elevated concentrations even if grown in pristine *** estimated intake rate of Cd in the fruiting bodies indicates cause for concern associated with this metal resulting from the daily consumption of between 200 and 400 g of fruiting bodies on a frequent basis during the mushrooming season.

Since the establishment of the People’s Republic of China, both the Communist Party and the government have placed great emphasis on the advancement of traditional Chinese medicine. Acupuncture and moxibustion have been actively involved in combating major epidemics such as malaria, schistosomiasis, and COVID-19. This article conducts a historical review of these three significant cases to elucidate how the acupuncture community has effectively utilized its unique advantages and characteristics through theoretical discussions, clinical practices, experimental research, as well as receiving administrative leadership and political support from the Communist Party of China and government. We provide an objective evaluation of their effectiveness while summarizing historical experiences to serve as a reference for future utilization of acupuncture and moxibustion therapy in epidemic relief efforts. Additionally, propose four suggestions: strengthening Party leadership and enhancing political support;timely summarization of experiences to establish programs and systems;deepening scientific research by integrating experimental findings with clinical practice;focusing on public awareness campaigns and education to solidify grassroots foundations.

Natural rivers usually possess sand waves and sand bars. In this article, the rapid distortion theory was used to study the turbulent flow over sand waves. The results show that the pre-existing sheafing motion and upstream anisotropy of the turbulence flow would have significant effect on the turbulent structures, and hence the memory effect should be taken into consideration. Furthermore, the 2-D mathematical model was employed to simulate the unsteady flow around the Taiping Sand Bar in the lower reach of the Yangtze River and the time step effect on the unsteady flow simulation with the implicit scheme was discussed at the same time. The results show that the implicit scheme keeps effective until the time step reaches a certain number, and the calculated water levels and velocities are in agreement with the observed data.

Pharmacokinetics of cyadox （CYX） and its major metabolites in healthy swine was investigated in this paper. 1,4- Bisdesoxycyadox （BDCYX）, cyadox-1-monoxide （CYX-1-O） and quinoxaline-2-carboxylic acid （QCA）, three main metabolites of cyadox, were synthesized by College of Science, China Agricultural University. Cyadox （CYX） was administered to 8 healthy cross-bread swine intravenously （i.v.） and orally （p.o.） at a dosage of 1 mg kg^-1 body weight and 40 mg kg-1 body weight respectively in a randomized crossover design test with 2-wk washout period. A sensitive high-performance liquid chromatography-tandem mass spectrometry （LC-ESI-MS/MS） method was developed for the determination of cyadox and its major metabolites in plasma. CYX and its major metabolites BDCYX, and CYX-1-O can be detected after intravenous administration of cyadox while CYX and its metabolites BDCYX, CYX-1-O and QCA can be detected after oral administration of CYX. Plasma concentration vs. time profiles of CYX and its major metabolites were analyzed by non-compartmental pharmacokinetic method. Following i.v. administration, the areas under the plasma concentration-time curve （AUC0-∞） were （0.38±0.03） lag mL-I h （CYX）, （0.018±0.002） lag mL-1 h （BDCYX） and （0.17±0.02） lag mL^-1 h （CYX- 1-O）, respectively. The terminal elimination half-lives （t1/2kz） were determined to be （0.93±0.07） h （CYX）, （1.45±0.04） h （BDCYX）, and （0.92±0.04） h （CYX-1-O）, respectively. Steady-state distribution volume （Vss） of （2.14±0.11） L kg^-1 and total body clearance （CL） of （2.84±0.19） L h^-1 kg^-1 were determined for CYX after i.v. dosing. The bioavailability （F） of CYX was 2.85% for oral administration. After single i.v. administration, peak plasma concentrations （Cmax） of （1.08±0.06） lag mL^-1 （CYX）, （0.0068~ 0.0004） lag mL-1 （BDCYX） and （0.25~0.03） gg mL-~ （CYX-I-O） were observed at Tmax of 0.033 h （CYX）, 1 h （BDCYX） and 0.033 h （CYX-1-O）, respectively. The main pharmacokinetic parameters after p.o. administration were as

AIM: To investigate apoptosis in human pancreatic cancer cells induced by Triptolide (TL), and the relationship between this apoptosis and expression of caspase-3' bcl-2 and bax. METHODS: Human pancreatic cancer cell line SW1990 was cultured in DMEM media for this study. MTT assay was used to determine the cell growth inhibitory rate in vitro. Flow cytometry and TUNEL assay were used to detect the apoptosis of human pancreatic cancer cells before and after TL treatment. RT-PCR was used to detect the expression of apoptosis-associated gene caspase-3' bcl-2 and bax. RESULTS: TL inhibited the growth of human pancreatic cancer cells in a dose-and time-dependent manner. TL induced human pancreatic cancer cells to undergo apoptosis with typically apoptotic characteristics. TUNEL assay showed that after the treatment of human pancreatic cancer cells with 40 ng/mL TL for 12 h and 24 h, the apoptotic rates of human pancreatic cancer cells increased significantly. RT-PCR demonstrated that caspase-3 and bax were significantly up-regulated in SW1990 cells treated with TL while bcl-2 mRNA was not. CONCLUSION: TL is able to induce the apoptosis in human pancreatic cancer cells. This apoptosis may be mediated by up-regulating the expression of apoptosis- associated caspase-3 and bax gene.
