Discussion on medical equipment support in actual combat training / 医疗卫生装备

Objective To explore medical equipment support in actual combat training to improve mobile medical unit in medical service support.Methods Combined with the characteristics of actual combat training,the problems and difficulty of medical equipment support were discussed in actual combat training.Results Some measures were put forward for medical equipment support such as cherishing of medical serviceman on equipment,equipment quality control and maintenance beforeutilization,effective protection and fixation,minimization of influence of instable power supply and plan preparation for loading and transport.Conclusion The study on medical equipment support in actual combat training contributes to enhancing medical support ability of mobile medical unit.

Flavonoids with special B-ring from Macrothelypteris viridifrons and their anti-proliferative effects on tumor cell / 中国中药杂志

<p><b>OBJECTIVE</b>To study the chemical constituents of Macrothelypteris viridifrons and their anti-proliferative effects on tumor cell.</p><p><b>METHOD</b>The compounds were isolated by column chromatography with silica gel, C18 reverse-phase silica gel, sephadex LH-20, and their structures were elucidated on the basis of physiochemical propertities and spectral analysis. The antitumor activities of all compounds were tested with MOLT4, Hep G2, A-549, MCF-7, HT-29, PC-3 tumor cell lines.</p><p><b>RESULT</b>Five compounds were isolated and identified as protoapigenone (1), protoapigenin (2), protoapigenin-4'-O-beta-D-glucopyanoside (3), 5,7-dihydroxy-2-(1,2-isopropyldioxy-4-oxo-cyclohex-5-enyl) -chromen-4-one (4), 5,7-dihydroxy-2-(1-hydroxy-2,6-dimethoxy-cyclohex-4-oxo) -chromen-4-one (5), respectively.</p><p><b>CONCLUSION</b>All compounds were obtained from this plant for the first time. Compounds 1, 4 and 5 showed strong anti-proliferative effects on six tumor cells, which were in concentration-dependent manner.</p>

Development and evaluation of the sinomenine transdermal patch

Sinomenine transdermal patch was prepared and its properties were studied. The patches were produced by salivation method. The releasing rate in vitro of the patch was determined by HPLC. Peel test was used to evaluate the adhesion. Acute skin irritation test was performed in comparison with formalin [0.8%] by using mouse model. The Sinomenine TDDS Patch was prepared. The releasing rate in vitro followed the Higuchi equation [r>0.99], the releasing amount was beyond 90% in 24h. The peel adhesion to steel [N/25 mm] is 10 or above. The skin irritation tests showed negligible erythema and edema. The Sinomenine transdermal patch was prepared successfully and it may be beneficial for topical use

Anti-inflammatory and analgesic activity of topical administration of siegesbeckia pubescens

Several topical formulations containing methanolic extract of Siegesbeckia pubescens was investigated for antiinflammatory and analgesic activities in rat. The effects were studied using carrageenan-induced edema and formalin testing. Piroxicam gel and methyl salicylate ointment were studied as positive control for antiinflammatory and analgesic activity, respectively. The edema inhibition of the preparations containing extract at the doses of 1-5% w/w were significantly different from the control group. The antiinflammatory effect of Siegesbeckia pubescens 4-5% w/w was similar to the effect of piroxicam gel 3 h after carrageenan injection. The analgesic activity of topical preparation with more than 4% w/w was observed in the late phase. The topical analgesic activity of the extract was less than the analgesic activity of methyl salicylate ointment. The results of the present study further confirm the use of Siegesbeckia pubescens traditionally for the treatment of painful inflammatory conditions and can be useful for the treatment of local inflammation
