The application discloses a dislocation tooth storage and treatment box and a storage and treatment method. The box comprises a box body and a box cover. One side of the box cover is hinged to the box body, and the other side of the box cover is detachably connected to the box body. The box body is internally provided with a cleaning groove, a liquid storage groove, a tooth storage groove and a storage groove. The cleaning groove and the tooth storage groove penetrate through the bottom of the box body, and a sealing plug is detachably connected to the bottom of the box body. The cleaning groove, the liquid storage groove and the tooth storage groove are respectively detachably connected with a cleaning groove cover, a liquid storage groove cover and a tooth storage groove cover, which are fixedly connected to the box cover. A pair of tweezers is detachably connected to the storage groove. The scheme uses physiological saline to flush dirt on the dislocation tooth, uses HBSS to maintain and recombine cell components consumed by periodontal membrane cells, provides a good storage environment, uses HBSS containing ALN to treat the dislocation tooth to reduce root absorption after replantation, avoid bone adhesion and improve the replanting success rate.

The application discloses a method and a kit for detecting urinary system cancer based on urine DNA methylation, and belongs to the field of biotechnology and medical detection. The method only needs to take 10 mL of urine, centrifuges the supernatant, takes urine sediment to perform DNA extraction and bisulfite conversion. The converted DNA is used to detect the methylation state of four methylation target genes H4C6, SIX6, SHOX2 and SEPTIN9 by real-time fluorescent quantitative PCR. The application establishes a methylation marker combination taking H4C6, SIX6, SHOX2 and SEPTIN9 as the core and a matching detection method and kit, and realizes non-invasive, stable and efficient detection of various malignant tumors (bladder tumor, ureter tumor, renal pelvis tumor, kidney tumor and prostate tumor) of the urinary system.

This invention discloses a charging control system and method for a pure electric bus, comprising a high-voltage electrical box, a low-voltage battery, and a charging switch. The high-voltage battery is housed in the high-voltage electrical box and connected to a DC-DC converter module. The DC-DC converter module is connected to a charging power supply. The high-voltage battery is also connected to a battery management system (BMS), which is connected to the low-voltage battery. A charging switch is installed on the connection circuit between the low-voltage battery and the BMS. When the charging switch is closed, the low-voltage battery provides activation power to the BMS, activating it. The BMS can also be connected to the auxiliary power supply of a standard charging gun, which provides activation power to the BMS, activating it as well. Once the BMS is activated and determines that the high-voltage battery is charging normally, the DC-DC converter module provides low-voltage power to the charging power supply. This system integrates power distribution control for both standard and non-standard charging guns.
