The invention discloses applications of dihydro chromone framework compounds of CPQ-16, CPQ-17, CPQ-20, CPQ-22, CPQ-23 and CPQ-24 in preparing medicine for curing malignant tumors. According to experimental proof, any kind of the six compounds can kill a plurality kinds of tumor cells of human bodies effectively, the tumor cells comprise cervical cancer cells, non-small cell lung cancer cells, breast cancer cells, ovarian carcinoma cells, hepatoma carcinoma cells, nasopharyngeal carcinoma cells, gastric carcinoma cells, laryngocarcinoma cells, pancreatic cancer cells, melanoma cells, bladder cancer cells and leukemia cells. Besides, with increase of dosages of the compounds, injured and killed cancers are increased with the increase of the dosages, and thus the new applications are proofed and discovered in the medicine for curing malignant tumors, and a new application range is exploited. Besides, new medicine is provided for the malignant tumors, and the difficulty in the chemical treatment of diseases that tumor cells are tolerant of chemotherapeutics is solved.

The invention provides a microstrip switch type phase shifter and a phase shifting module using the same. The microstrip switch type phase shifter comprises a reference branch circuit, a phase shifting branch circuit, a first path selection switch and a second path selection switch, wherein the reference branch circuit comprises a first microstrip transmission line; the phase shifting branch circuit comprises a second microstrip transmission line and a third microstrip transmission line which are connected in series, and a fourth microstrip transmission line connected between a node between the second and third microstrip transmission lines and the ground level; the front end of the first path selection switch is connected to a signal input end, the rear end of the second path selection switch is connected to a signal output end, and the first and second path selection switches are simultaneously connected to the reference branch circuit and the phase shifting branch circuit under control. By adopting continuous microstrip lines and a simple topological structure, the phase shifter and the phase shifting module reduce parasitical parameters caused by discontinuous microstrip lines, can be applied to high-frequency scenarios, meanwhile, have very flat phase shifting characteristic nearby center frequency by simulation and experimental proof, and have high phase shifting precision.

The invention relates to a new application of a HuGu capsule (HG) in preventing glucocorticoid-induced osteoporosis (GIO), belonging to the technical field of traditional Chinese medicine application. The invention discusses HG prevention effect towards GIO induced by glucocorticoids (GCs) based on bone histomorphometry. The experimental result proves that the glucocorticoids (GCs) can induce cortical bone loss of a rat in short time, after HG intervention is carried out for 45d, the GCs is prevented from inducing the cortical bone loss of the rat, thereby providing experimental proof for thenew application of the HG in preventing the GIO.

The invention belongs to the field of biotechnology and medical science and particularly relates to a diabetic retinopathy (DR) metabolic memory detection reagent and application thereof. According to experimental proof, methylation of locus (+214) in a peroxisome proliferator-activated receptor gamma coactivator 1 alpha (PGC1-alpha) gene is an early diagnosis mark of DR metabolic memory. On the basis of the study, the detection reagent is provided for detecting the diagnosis mark, and a corresponding detection kit is prepared. According to the provided methylation detection reagent, whether methylation of a detected object of the PGC1-alpha gene locus +214 occurs or not and methylation degree can be qualitatively or quantitatively detected, thereby, whether DR metabolic memory and illness risks of the detected object exist or not can be predicted, and the clinical application value is excellent.

The invention discloses a connected metal link heat treatment process method. The method comprises the following steps of: wrapping up an insulation layer on the outer surface of the connected link, and heating an inner metal through an outer induction coil so that the heat in the connected link is difficult to escape; and meanwhile, winding cooling pipes on other links close to the connected link, and rapidly taking away the heat generated in the connected link by the cooling pipe so that the other links are not affected. Through an experimental proof, the nearby links, particularly the connected links have the temperature lower than 150 DEG C in the heat treatment process, so that the requirement of classification society rule to chains processing is completely met.

The invention discloses a compound traditional Chinese medicinal water extract for treating acute pancreatitis. Calculated in parts by weight, 22-27 parts of gardenia, 22-27 parts of paeonol, 22-27 parts of woody fragrance and 22-27 parts of magnolia 22-27 parts of Yuanhu, 35-45 parts of Radix Paeoniae Rubra, 35-45 parts of Rhubarb and 12-17 parts of Glauber's Salt as raw materials for preparation. The present invention selects 8 kinds of traditional Chinese medicine compositions as raw materials for preparation, and applies the prepared water extract to the medicine for treating acute pancreatitis. According to experiments, the prepared medicine can obviously relieve abdominal distension and intestinal paralysis during SAP, Thus, the symptoms of SAP can be significantly relieved, complications can be reduced, and the mortality rate can be reduced. After more than 5,000 cases of acute pancreatitis and more than 1,000 cases of acute severe pancreatitis (SAP), the treatment and summary have received good curative effect. The cure rate of SAP can reach 85.4%, and the mortality rate has dropped to 10.1%. The material source of the invention is wide, easy to obtain, and low in cost, and the preparation method adopted is simple and easy to implement and easy to industrialize.

The invention particularly relates to an electromagnetic thermal therapy suit and a power source knapsack matched with the electromagnetic thermal therapy suit and belongs to the field of electromagnetic thermal therapy instruments. The electromagnetic thermal therapy suit comprises a clothing body and is characterized in that a therapy interlayer is arranged in the clothing body, and 2n magnetic stripes are fixed in the therapy interlayer and arranged in pairs in a mutually parallel mode. Coils are wound on the magnetic stripes. The winding directions of the coils on the adjacent magnetic stripes are opposite. All the coils are connected with inverters together through wires in series, and power interfaces are arranged in the inverters. According to the electromagnetism theory and experimental proof, when the electromagnetic thermal therapy suit is close to the human body, a coupling circuit is formed. After the coupling circuit is formed, electric currents in the thermal therapy suit are induced to the biological circuit of the human body, so that the purposes that the human body currents are adjusted and intensified, and the biological magnetic field is improved are achieved. The thermal therapy suit also can enable the human body to continuously generate a sense of warmth and a temperature needed for maintaining physical health and is particularly suitable for being used by an outdoor worker in winter, a mountaineering enthusiast, a surfer and other activity persons in the low-temperature environment.

The invention discloses a coil support which comprises a bottom plate and a plurality of basic blocks, wherein the bottom plate comprises a plurality of mounting positions arranged along preset direction, the basic blocks are detachably arranged on the mounting positions, and the two adjacent basic blocks are matched to form a clamping groove for clamping litz wires.
