The utility model relates to the technical field of keyboards, and discloses a Bluetooth wireless keyboard with a calculator function, which comprises a base, a keyboard main body is arranged at the top of the base, rotating lugs are rotatably arranged at the front ends of the left side and the right side of the keyboard main body, and the bottoms of the rotating lugs are fixed on the base. Fixing frames are fixed to the left side and the right side of the top of the base correspondingly. Compared with the prior art, the angle of the keyboard body is adjusted, so that the adjusting range of the keyboard is greatly expanded, the expanded adjusting range can meet the requirements of more users, and the greatly expanded adjusting range can realize finer angle adjustment, so that the users can find the most suitable angles, and the user experience is improved. In general, the keyboard has an angle adjusting function and has a larger adjusting range, more comfortable and personalized use experience can be brought to a user, and the keyboard conforms to the human engineering design principle.

This invention discloses a multiplex PCR primer combination, kit, and detection method for detecting Echinococcus granulosus. The multiplex PCR primer combination includes a second primer combination and a third primer combination: the second primer combination consists of upstream and downstream primers specific to Echinococcus multilocularis, with sequences shown in SEQ ID NO. 3 and SEQ ID NO. 4, respectively; the third primer combination consists of upstream and downstream primers specific to Echinococcus shiquensis, with sequences shown in SEQ ID NO. 5 and SEQ ID NO. 6, respectively. This invention saves more time than conventional PCR, is more cost-effective than quantitative real-time PCR, and has lower requirements for operators and equipment, showing great promise for the detection and control of echinococcosis.

The invention provides a vaginal secretion staining solution, a preparation method and a method for staining by applying the vaginal secretion staining solution, and belongs to the technical field of cell staining. The alkaline toluidine blue basic dye is used as a coloring agent, the phosphate buffer solution is used as a solvent, the sodium hydroxide is used as a regulator, the components are simple, the preparation is convenient, the dyeing method is rapid, epithelial cells, leukocytes and bacilli can be dyed, trichomonad and mould cannot be dyed, the leukocytes and the trichomonad can be obviously distinguished through color difference, and the method is suitable for large-scale popularization and application. In addition, the colored bacilli can intuitively assist in cleanliness discrimination and clue cell identification, so that personnel misjudgment caused by similar forms of detection targets can be avoided, and the problems that the current dye liquor has many components, the preparation method is tedious, the dyeing method is complex, the detection time is short and the like are solved. And the problem of lack of a sample tube dropwise adding dye liquor proportioning scheme is solved.
