China emerges as a major country in nuclear energy development and the application of nuclear and radiologic technology. The diagnosis and treatment of acute radiation syndrom (ARS) caused by external irradiation represent a core function in the country′s medical rescue of nuclear and radiological emergencies. Clinically, ARS manifests hematopoietic, gastrointestinal, cutaneous, and central nervous system syndromes, with specific clinical manifestations, signs, severity, and prognosis strongly correlated with radiation dose. China has established a number of national and provincial centers for treating radiation-induced damage. Nevertheless, most medical staff have limited experience in ARS treatment. This consensus presents a summary of recent experience in treating ARS of China. In combination with recommendations from international organizations such as the World Health Organization (WHO), this consensus proposes key evidence of critical clinical issues of ARS, covering all links in the rescue of external irradiation-induced ARS. Initially, clinical diagnosis, syndromes, and severe degrees should be determined based on clinical symptoms and dose estimates. It is necessary to normalize clinical treatment measures for hematopoietic recovery, gastrointestinal injury treatment, infection control, symptomatic treatment, and multi-organ function preservation. To this end, this consensus offers cautions. This consensus provides principles of treatment with traditional Chinese medicine, psychological intervention, and follow-up. Additionally, it highlights multidisciplinary collaboration. It is recommended that this consensus be applied in relevant treatment centers.

Objective To establish a HPLC fingerprints of Biyuanjing capsules. Methods The column was Agilent SB-C₁₈(4.6mm×250 mm, 5 µm). The mobile phase was acetonitrile-water with gradient elution at a flow rate of 1.0 ml/min. The detection wavelength was 210 nm. The detection time was 80 min. Results The HPLC fingerprints of Biyuanjing capsules were established. Twenty common peaks were confirmed, of which, 15 peaks were belonging to each crude drug and 5 peaks were identified as chemical components. The overall similarity of the fingerprints of 10 batches of samples was above 90% comparing with the control. Conclusion This method can be used for the quality control of Biyuanjing capsules.

Objective To synthesize a series of 13-acylmatrine derivatives and evaluate their in vitro antitumor activity . Methods Using sophocarpine as the starting material ,a series of new compounds were synthesized through Michael addition , Staudinger reduction and acylation .The structure of target compounds were confirmed by 1 H NMR and MS techniques .Their antitumoractivityagainsthumanhepatomacells(BEL-7404)andmicemelanomacells(K111)wereevaluated invitrobyMTT assay .Results We synthesized 9 compounds and all the compounds exhibited inhibitory activities against BEL-7404 and K111 . Conclusion Compound 4b and compound 4e exhibit good in vitro antitumor activity to human hepatoma cells (BEL-7404) .

Objective:To compare the steam distillation( SD) and supercritical CO2 ( SFE-CO2 ) method in the extraction of vola-tile constituents from such 3 traditional Chinese drugs as cnidium monnieri, radix sileris and atractylodes lancea in compound Kuhuang prescription. Methods:Essential oil was extracted from the 3 traditional Chinese drugs by SD and SFE-CO2 method, respectively. The components were identified by GC-MS, and their relative contents were calculated with peak area normalization method. Results:To-tally 36 components were isolated and identified using SD extraction and 31 components were identified using SFE-CO2 extraction, a-mong them, 22 components were the same and their relative molecular weight mainly concentrated within 200-230. Conclusion: SFE-CO2 method can extract effective components from the 3 traditional Chinese drugs in compound Kuhuang prescription with higher selec-tivity, which is the more suitable extraction method for essential oil from the prescription.

Objective To investigate the proliferation inhibition of chlorpromazine combined with taxol on Hep-2 cells (human laryngeal carcinoma cell line) and the effects on cell cycle progression. Methods Hep-2 cells at logarithmic growth phase were divided into taxol groups(3.0,6.0 and 12.0 mg?L-1),chlorpromazine(12.0 mg?L-1) comined with taxol (4 mg?L-1)group and control group (100 mL culture fluid).MTT and flow cytometry were used to detect the proliferation inhibition rates of Hep-2 cells in various groups.Flow cytometry was also used to analyze the cell cycle progression of Hep-2 cells and apoptotic rate after administration.Results The proliferation inhibition rates in 3.0,6.0 and 12.0 mg?L-1 taxol groups were 14.0%,23.9% and 36.7%,respectively,there were significant differences between three groups(P

AIM: To investigate the effect of Ba 2+ concentration on L-type of Ca 2+ channel in hypothalamic neurons.METHODS: The cell acute isolation technique and cell-attached patch-clamp technique were used. RESULTS : The slope conductance of L-type Ca 2+ channel were 28.6 pS (110 mmol/L) and 19.1 pS (10 mmol/L), and the open probability (NP 0) obviously different with different Ba 2+ concentration as carrier. CONCLUSION: Ba 2+ concentration had the obvious effect on the L-type Ca 2+ channel.
