Measuring the content of soluble reducing sugar, total sugar, soluble protein, guanosine, alkaloids, and succinic acid of Pinellia ternata tuber were measured by anthrone-sulfuric acid colorimetric method, Coomassie brilliant blue method, RP-HPLC, reverse potentiometric titration, acid dye colorimetry, respectively. The result showed that yellow light could promote the growth and development of P. ternata and increase the content of soluble reducing sugar, total sugar, alkaloids, and succinic acid. Under blue light could promote the content of soluble protein and guanosine. Red and yellow light increased the content of chlorophyll a and chlorophyll b, contrastively blue light reduced the content of chlorophyll a and chlorophyll b. White film through the most uniform spectrum was most conducive to the synthesis of chlorophyll a. As single film, blue film, yellow film were more conducive to the synthesis of chlorophyll a, green film and red film had been relatively beneficial to the synthesis of chlorophyll b. Bulbil formed the largest number and the biggest propagation coefficient of P. ternata under red light showed that it could increase the production of P. ternata under red light.

Objective To investigate the different expressions of adiponectin receptor 2(AdipoR2) mRNA in liver between diet-induced obese rats and controls.Methods The level of AdipoR2 mRNA expression was detected by reverse transcriptase polymerase chain reaction(RT-PCR).Insulin sensitivity was evaluated by insulin sensitivity index(ISI).Results Diet-induced obese rats showed higher expression of AdipoR2 mRNA compare to controls.The ISI of diet-induced obese rats was lower than that of controls.Conclusion High energy diet induceds AdipoR2 expression in liver.

AIM: To investigate the effect of glibenclamide (Glib) on the viability and acid-base equilibrium of glioblastoma cells.METHODS: U251 cells and U87 cells were treated with Glib at different concentrations.The inhibitory rates were detected by CCK-8 assay.The effective dose was screened and the experiment was divided into control group and drug treatment groups.The migration ability was monitored by wound healing assay, and intracellular pH was detected by pH indicator fluorescent probe.The protein expression levels of inwardly-rectifying potassium channel 4.1 (Kir4.1) and monocarboxylate transport protein 1 (MCT1) were determined by Western blot.RESULTS: The half maximal inhibitory concentrations (IC50) of Glib for 48 h exposure of U251 cells and U87 cells were 400.20 μmol/L and 553.70 μmol/L, respectively.The effective inhibition doses of Glib for U251 cells were from the ranges of 100 μmol/L to 1 600 μmol/L, and those for U87 cells were from 50 μmol/L to 1 600 μmol/L in a concentration-dependent manner (P<0.05).Glib not only inhibited the migration (P<0.05) of U251 cells and U87 cells, which was negatively correlated with drug concentration (P<0.05), but also reduced the intracellular fluorescence intensity in experimental group (P<0.05), suggesting that with the increase in drug concentration, the intracellular pH decreased gradually (P<0.05).The protein expression of Kir4.1 and MCT1 was down-regulated by treatment with Glib, and was negatively correlated with concentration of Glib.CONCLUSION: Glib, a kind of potassium channel blocker, induces intracellular acidification via down-regulating the expression of Kir4.1 and MCT1, thus inhibiting the growth of glioblastoma in a certain dose range.

Objective To evaluate the effects of various polysorbates(PS)on the stability of different types of monoclonal antibody(mAb)drugs.Methods Three types of monoclonal antibodies mAbA(IgG1 proantibody drug),mAbB(IgG1 mAb)and mAbC(IgG1 mAb with Fc N297A mutation)were used as model proteins,and different kinds or contents of PS were added into the mAb formulations respectively to investigate the influencing factors.The effects of PS on the stability of mAb drugs were evaluated comprehensively by detecting the changes of quality attributes,such as protein aggregates and insoluble particles.Results PS20 and PS80 showed no significant difference in inhibiting the formation of aggregates and charge variants in the three mAbs(P>0.05),while the addition of PS80 in mAbB and PS20 in mAbC significantly inhibited the increase of insoluble particles respectively(P<0.05);The content of PS20 showed a significant effect on the detection indexes of charge variants and insoluble particles in mAbC(P<0.05).Conclusion Different types of mAbs have different sensitivities to various kinds and contents of PS.Therefore,when designing the formulation of mAbs,it is necessary to select appropriate kinds and contents of PS to further improve the stability of mAb drugs.

In order to optimize the testing methods for Paeonia suffruticosa seed quality, and provide basis for establishing seed testing rules and seed quality standard of P. suffruticosa. The seed quality of P. suffruticosa from different producing areas was measured based on the related seed testing regulations. The seed testing methods for quality items of P. suffruticosa was established preliminarily. The samples weight of P. suffruticosa was at least 7 000 g for purity analysis and was at least 700 g for test. The phenotypic observation and size measurement were used for authenticity testing. The 1 000-seed weight was determined by 100-seed method, and the water content was carried out by low temperature drying method (10 hours). After soaking in distilled water for 24 h, the seeds was treated with different temperature stratifications of day and night (25 degrees C/20 degrees C, day/night) in the dark for 60 d. After soaking in the liquor of GA3 300 mg x L(-1) for 24 h, the P. suffruticos seeds were cultured in wet sand at 15 degrees C for 12-60 days for germination testing. Seed viability was tested by TlC method.
