Objective To investigate the effects of capsaicin on the invasion ability of human large cell carcinoma NCI-H460 and the expressions of E-cadherin and Snail;To discuss the possible mechanisms of anti-non-small cell lung cancer.Methods NCI-H460 cells were cultured in vitro and treated with capsaicin at various concentrations, and no capsacin-treated group was set as control group. Effects of capsaicin on NCI-H460 apoptosis, its invasion ability, and the changes in protein expressions of E-cadherin and Snail were evaluated by Hoechst33342 nuclear staining assay, Transwell chamber invasion assay, and Western blot respectively. Results Compared with the control group, Hoechst33342 nuclear staining assay showed that capsaicin could induce NCI-H460 cell apoptosis (P<0.05);Transwell invasion in vitro results showed that capsaicin could significantly inhibit invasion of penetrating cells (P<0.05);Western blot analysis showed that E-cadherin expression level was significantly elevated and snail expression level significantly decreased (P<0.05).Conclusion Capsaicin can induce NCI-H460 cell apoptosis. Decrease the Snail expression and stimulate E-cadherin expression so as to inhibit the invasion ability of NCI-H460, which may be one of its mechanisms of anti-non-small cell lung cancer.

Objective To investigate and analyze the clinical application of washed red blood cells in Quzhou in 2014-2015 years,and to provide evidence for the rational and effective use of washed red blood cells in clinical practice.Methods the amount of washed red blood cells,the distribution of diseases and the serological detection before transfusion were analyzed retrospectively in 8 hospitals of grade two and over in Quzhou during the past 2014-2015 years.Results the amount of washed red blood cells in 2015 increased by 39.07％ compared with 2014,an increase of 24.4 times the amount of red blood cells increase,increase mainly in 3 hospitals;Diseases of the blood system,malignant tumors and chronic kidney disease is the main diagnosis of transfusion cases,accounted for 63.49％,19.05％,12.70％.There were different standards for the development of serological testing items before transfusion Conclusion the advantages of washed red blood ceils gradually recognized by clinicians,but also don't rely on experience,hospitals should pay attention to the comprehensive evaluation of clinical blood transfusion and standardize the serological detection of blood transfusion department,which is the key to improve the cost performance of this component.

Objective To discuss the effect of quick freezer equipment and quick freezing time on the preparation of cryoprecipitate.Methods The cryoprecipitate,already prepared,was placed into the MBF21 freezer and minus 30℃ SANYO refrigerator for 30-minute and 50-minute storage.The activity of coagulation factor VⅧ,and the content of fibrinogen in different equipment were detected by automatic coagulation analyzer,in order to make sure whether it met the quality requirements.Results The content of fibrinogen in the cryoprecipitates from both of the equipment after 30-minute storage met the requirement,with the qualification rate of 100％.As to the activity determination of coagulation FⅧ,low temperature refrigerator showed a qualification rate of 62.5％,which was significantly lower than that of quick freezer with a qualification rate of 97.5％ (P＜0.01).The cryoprecipitates from both of the equipment after 50-minute storage,with part of fibrin precipitation,had a qualification rate of fibrinogen content lower than 50％ (P＞0.05).The qualification rate of quick freezer and low temperature refrigerator was 35％ and 12.5％,respectively,with significant difference.Conclusion Quick freezer can make the cryoprecipitate quick-frozen,which can ensure the quality.The coagulation factor VⅧ is unstable,whose activity decreased with the increase of temperature.We should try our best to shorten the time off the cold chain.

OBJECTIVE: The medicinal mushroom Sanghuangporus vaninii produces pharmaceutically valuable hispidin polyphenols in natural habitats. However, due to the slow growth in nature, S. vaninii grown in the field (sclerotia) is not reliable for pharmaceutical purposes. Although higher biomass of fungal mycelia can be obtained in submerged cultures, the accumulation of hispidin polyphenols is rare. METHODS: In this study, the polyunsaturated fatty acids (PUFAs), linoleic acid (LA), linolenic acid (ALA), and methyl jasmonate (MeJa) were employed as the stimulant agents to coordinate the accumulation of biomass and hispidin polyphenols in its submerged cultures. RESULTS: The addition of LA and ALA promoted the mycelial accumulation, while the addition of MeJa inhibited the growth of S. vaninii concomitant with reduced total polyphenols. UPLC-Triple-TOF-MS analysis revealed an increased production of hispidin, phellinstatin, pinnilidine, and its derivatives upon the addition of LA and ALA, and hypholomine B and its isomer, 3,14'-bihispidinyl, and phelligridin E upon the addition of MeJa on day 13. Intriguingly, total polyphenols from the MeJa-supplementing cultures harbored a high capacity in scavenging free radicals. Chemical structural analysis showed that hispidin polyphenols had higher antioxidant activity due to more hispidin moieties induced by MeJa. CONCLUSION The supplement of PUFAs affects the synthesis and composition of hispidin polyphenols in S. vaninii. Our results provide a possibility to coordinate the production of hispidin polyphenols via submerged cultures of S. vaninii.
