The invention discloses a composition for preventing and treating HIV / AIDS and a preparation method thereof. The pharmaceutical composition is prepared from ginseng, cordyceps sinensis, angelica, astragalus, salvia miltiorrhiza, coix seed, poria cocos, rehmannia glutinosa, hawthorn, malt, divine comedy and licorice according to a certain weight ratio. The composition has the effects of nourishing qi and blood, invigorating the spleen and benefiting the lungs, and can be used to treat AIDS and HIV-infected patients with deficiency of qi and blood, such as mental fatigue, shortness of breath, lazy speech, anorexia, spontaneous sweating, and easy cold; dizziness Dizziness, palpitations, insomnia, numbness of hands and feet, etc. It is prepared as any oral formulation, preferably tablet.

The invention relates to a pulsed sustained-release pellet comprising nimodipine and a preparation method is also provided. The sustained-release pellet comprises: one of gastric-dissolved and medicines containing sustained-release pellets and enteric-coated and medicines containing sustained-release pellets, or the combination. The preparation method is that: making medicines containing pellets using nimodipine and excipents, coating the medicines containing pellets with the gastric coating or the enteric coating, mixing the sustained-release pellets coated with gastric coating and enteric coating in proportion and putting the sustained-release pellets into capsules or tabletting. The pulsed sustained-release pellet of the invention has a special release behavior and needs to be taken only once per day. The release curve agrees well with the disease circadian rhythm of cerebrovascular disease patients, playing a role of the best prevention and treatment.

The invention belongs to the field of pesticide bioassays, and specifically discloses an artificial inoculation method for the spodoptera moth. The present invention coats corn seeds with the medicament to be tested, or sprinkles poisonous baits or granules of the medicament to be tested at the stem base of corn seedlings; Inoculation, and the inoculation medium was placed at the base of the corn seedling stem, covered with a protective cover, and the larvae were placed on the inoculation medium for investigation. The present invention provides accurate, reliable method for the insecticide screening of preventing and treating the two-spotted moth; secondly, the 3rd instar larva that the present invention selects is strong to the sensitivity of medicament, food intake is big, and activity ability is strong, and its to corn seedling The feeding probability is large; in addition, the setting of the inoculation medium and the protective cover in the inventive method makes the larva escape rate low, and can avoid the predation of natural enemies; the 2-3 leaf stage corn seedling stem base tissue young Tender, more suitable for larvae to feed on, and the symptoms will be obvious after being bitten.

The invention discloses a cannula used for dacryocystorhinostomy and a preparation method thereof. The cannula includes a drainage pipe, an oval drainage disc and a tail fixing screw are arranged at both ends of the drainage pipe respectively, the drainage pipe is in a hollow shape, a conduction channel is formed in the drainage pipe, a canula body is arranged at the tail end of the drainage pipe,and the cannula body is fixed to the tail fixing screw at a hole forming place in a nasal cavity through a buckle. A hollow silica gel catheter is selected and penetrated to serve as the drainage pipe, and the two ends of the drainage pipe are both polished for assembly of components; according to shape requirements, heating for shaping is conducted on the drainage pipe, and the drainage pipe iscooled naturally after thermoplastic shaping and disinfected for use. More convenience is provided for implanting, the drainage pipe only needs to be implanted from a lower lacrimal punctum and then can reach the hole forming place, extra traction devices are not required, only few minutes are consumed, and complicated treatment such as knotting is not required in the nasal cavity, so that patients feel comfortable, and no secondary injuries are caused; by designing the drainage pipe in a hollow shape, tears can be drained normally, infection is not caused easily, and symptoms are alleviated obviously during implanting.

The invention belongs to the technical field of biology and in particular provides a pectate lyase (PL) gene Pcpel1 which is cloned from phytophthora capsici and protein preparation technology thereof. Gene and protein levels prove that the gene is effectively involved in the process that the phytophthora capsici infects hot pepper hosts and results in occurrence of the course of diseases on hot pepper leaves. Plant pathology and cytochemistry technology further prove that after the protein coded by the gene is inoculated onto the hot pepper leaves, obvious withering and shrinking occur on the inoculated parts of the leaves and the cell walls on the affected parts of the leaves are obviously degraded, namely the gene code is an important protein related to the course of diseases or is possibly an important target pathogenic gene of a phytophthora capsici PL gene cluster. The invention provides important technical reserve for further developing phytophthora capsici molecule detection technology.

The invention discloses a folded cannula used for dacryocystorhinostomy and a preparation method thereof. The folded cannula includes a drainage header pipe and a drainage branch pipe, and a bubble bag is arranged on the drainage header pipe; an oval drainage disc and a tail fixing screw are arranged at both ends of the drainage branch pipe respectively, the tail fixing screw extends to an internal hole forming part of a nasal cavity, and a cannula body used for fixation is installed on the tail fixing screw through a buckle. A hollow silica gel catheter is selected, after the two ends of thesilica gel catheter are penetrated, the silica gel catheter is adopted as the drainage header pipe, and the drainage branch pipe is fixedly installed along the central axes of the two ends of the drainage header pipe; the end faces of the outer side of the drainage branch pipe are all polished, and the oval drainage disc and the tail fixing screw are additionally arranged; according to shape requirements, heating for shaping is conducted on the drainage pipes. More convenience is provided for implanting, extra traction devices are not required, complicated treatment such as knotting is not required in the nasal cavity, patients feel comfortable, and no secondary injuries are caused; by designing the drainage pipes in hollow shapes, tears can be drained normally, infection is not caused easily, and symptoms are alleviated obviously during implanting.
