Embodiments of the present invention relate to the field of electronic technologies, and disclose a bright screen duration adjustment method and a mobile terminal. The method comprises: detecting, by the mobile terminal, a touch operation input on a touch screen, obtaining a touch parameter of the touch operation, generating a bright screen duration adjustment command according to the touch parameter, responding to the bright screen duration adjustment command, and adjusting a current bright screen duration of the mobile terminal to a target bright screen duration that matches the touch parameter. According to the embodiments of the present invention, when detecting a pressing or slide operation on the touch screen, the mobile terminal adjusts the bright screen duration according to a duration or strength of the pressing or slide operation, thereby implementing meticulous adjustment on the bright screen duration, and improving bright screen duration adjustment efficiency of the mobile terminal.

The invention provides a method for screening a compound with lipase inhibition activity by magnetic bead separation. The method is used for rapidly screening the compound with lipase inhibition activity rapidly from fructus aurantii by adopting a magnetic bead separation and liquid chromatography-mass spectrometry combination method. Compared with the traditional method and the prior art, the method disclosed by the invention has the advantages of being capable of rapidly screening and identifying the compound with potential lipase inhibition activity from a mixture, further separating and preparing the target compound and carrying out activity verification, thereby greatly reducing the blindness of separating effective ingredients and improving the activity screening efficiency. During screening, the compound does not need to be prepared and separated, therefore the screening efficiency is remarkably improved and the screening time is shortened. In addition, the screening method has the characteristics of high speed, accuracy, good reproducibility and the like and can be popularized to be used for rapidly screening the compound with lipase inhibition activity from natural medicines or Chinese medicine mixture. The compound with lipase inhibition activity, obtained by using the method disclosed by the invention, can be applied to preparation of diet pills and lipid-lowering medicaments.

The invention discloses a plant transgenic visual tracking expression system and application thereof. The plant transgenic visual tracking expression system is a plant expression vector which contains a visual marker gene expression kit, the visual marker gene expression kit consists of an expression kit of a transcription factor bi gene in the anthocyanin biosynthetic pathway and an expression kit of a transcription factor cl gene in the anthocyanin biosynthetic pathway. The color regulator gene is applied on plant genetic transformation operation, the screening work is effectively relieved after the transformation, according to the gene performance on the plant, the valuable transformation materials can be selectively kept, accordingly, the screening time and the research cost are greatly saved, the accuracy and the reliability of the experimental result are greatly improved, so good foundation is laid for carrying out analysis work after the transformation. In addition, the transient expression of the color gene is utilized, the transformation effect can be visually and more directly analyzed, and accordingly, various transformation influencing factors are prevented from being generated.

The invention relates to a coal screening equipment, which comprises a bottom plate and four circular vibrating screens distributed around the center of the bottom plate, screens with different apertures are distributed in the vibrating screen, and a plurality of screens installed on the bottom plate to store multiple screens. There is a storage rack, and a conveying device for transporting the screen to the corresponding vibrating screen is distributed above the bottom plate, and a lifting mechanism is provided on the bottom plate to drive the storage rack up and down. The invention realizes multi-aperture screening of raw coal without multiple screening, reduces screening steps, shortens screening time, and transports sieve plates with different apertures into the corresponding vibrating screen through the cooperation of the conveying device and the lifting mechanism, without manual installation , Reduce the work intensity of workers, shorten the screening preparation time, and enhance the screening efficiency.

The invention discloses a method for quantitative screening of highly active yeast cells based on TTC staining method. The yeast cell liquid to be detected is coated on a flat plate, cultivated until a single colony grows; and then inoculated in each well of a 96-hole cell culture plate for culture. cultured in the culture medium until the measured OD value of the bacteria was between 1-3, then centrifuged and discarded the supernatant; added TTF extractant to each well of the 96-well cell culture plate, and centrifuged after shaking for 10-15S; the supernatant after shaking and centrifuging The supernatant was drawn into a 96-well microtiter plate, and the TTF absorption value was measured at a wavelength of 486nm by a microplate reader. According to the TTF standard curve and the measured cell OD value, the TTF content in each well was calculated to determine the cell viability. The screening results of the method can quantitatively and reliably directly reflect the cell viability, not only can obviously reduce the screening time, but also can reduce the human error caused by the visual judgment in the operation process.
