Description

Technical Field

[0001] This invention relates to the field of blood protein detection technology, and more particularly to a blood protein detection kit for the early diagnosis of newly diagnosed diabetic pancreatic cancer. Background Technology

[0002] Based on the UK Biobank database, this application screened newly diagnosed diabetic pancreatic cancer (NODM-PC) and newly diagnosed diabetes (NODM) controls using strict inclusion and exclusion criteria, and obtained standardized protein expression data using the Olink proteomics platform. After data quality control, missing value imputation, and differential analysis, 93 proteins with significantly different expression in the NODM-PC population were identified. To further verify the specificity of the biomarkers, this invention integrated protein expression profiles of pancreatic cancer and normal populations from the CPCAC database, as well as proteomics data of NODM-PC and non-diabetic pancreatic cancer (NonDM-PC) from published literature. Through multi-database intersection analysis, three core biomarkers with stable high expression in NODM-PC patients—PLTP, CRTAC1, and ITGAV—were finally screened.

[0003] Subsequently, multiplex immunofluorescence staining and ELISA experiments on clinical samples confirmed that the expression levels of these three proteins were significantly elevated in the tissues and blood of newly diagnosed diabetic pancreatic cancer patients. Based on this finding, this invention designs a detection kit that can simultaneously quantify the concentrations of PLTP, CRTAC1, and ITGAV in blood, providing a novel solution for early screening and risk warning of pancreatic cancer in newly diagnosed diabetic populations. Summary of the Invention

[0006] The bottom of the guide tube is connected to an air supply mechanism, which supplies temperature-adjustable air into the guide tube and generates bubbles that act on the spiral blades to drive the test tube to rotate. Several air vents are provided on the upper side wall of the guide tube.

[0007] A column is movably installed inside the lower part of the guide tube. The top of the column has an inner cavity. The lower end of the test tube is located in the inner cavity and is sealed by a sealing ring. A sewage discharge mechanism is provided on the bottom wall of the test tube and the lower part of the column.

[0008] Preferably, the reagent kit is divided into upper and lower layers. The upper layer has an independent placement cavity in the center. The water tank is arranged around the placement cavity. The inner wall of the water tank is lined with heat-insulating material and a temperature sensor is installed inside. The lower layer of the reagent kit has a movably placed wastewater box.

[0009] Preferably, a bearing is fixedly installed inside the boss, and the test tube is designed in a conical shape, passing through the bearing and entering the guide tube.

[0010] Preferably, a pressure plate is provided on the upper side of the test tube, and a pressure cap is threaded to the outer side of the boss. A sealing strip is provided between the two. An annular groove is provided on the inner top wall of the pressure cap. A sealing plate is movably installed in the annular groove. The lower end of the sealing plate is sealed to the test tube by a sealing ring. A ball bearing is embedded on the top of the sealing plate.

[0011] Preferably, the column and the bottom wall of the guide cylinder are connected by a bearing.

[0012] Preferably, a connecting tube is provided on one side of the bottom wall of the test tube, one end of which is connected to the inner cavity and the other end is connected to the inside of the guide tube.

[0013] Preferably, a temperature sensor is installed inside the guide cylinder, and the air supply mechanism includes a nozzle installed at the bottom of the guide cylinder. The input end of the nozzle is connected to an air pipe, and the end of the air pipe away from the nozzle is connected to an external air supply device. The air supply device can adjust the temperature of the output air in real time according to the data monitored by the temperature sensor in the guide cylinder.

[0014] Preferably, the sewage discharge mechanism includes a sewage discharge pipe located on the bottom wall of the test tube and the lower part of the column. An opening and closing component is provided on one side of the sewage discharge pipe. The opening and closing component includes a movable groove communicating with the sewage discharge pipe. A plug is rotatably installed at one end of the movable groove near the sewage discharge pipe. A slider is slidably installed inside the movable groove. A spring is connected between the end of the slider away from the plug and the inner wall of the movable groove. The slider is made of magnetic material. A magnetic attraction component is provided in the placement cavity. The magnetic attraction component acts on the slider.

[0015] Preferably, the magnetic suction assembly includes a mounting bracket disposed in the placement cavity, and electromagnets are mounted on multiple sides of the mounting bracket. The number and position of the electromagnets correspond one-to-one with the slider. When the electromagnets are energized, they generate an attractive or repulsive force on the slider.

[0016] Preferably, the top side of the water tank is provided with an exhaust pipe communicating with its interior. The top of the exhaust pipe is connected to a condenser pipe. The condenser pipe is designed to be horizontally inclined. Multiple cooling plates are evenly distributed on the inner top wall of the condenser pipe. Plate 1 and Plate 2 are distributed alternately inside the condenser pipe. Plate 1 is located at the bottom and has a notch between it and the bottom wall of the condenser pipe. The end of the exhaust pipe communicates with the interior of the placement cavity.

[0017] Compared with existing technologies, the advantages of this invention are:

[0018] 1. The reagent kit of this application constructs a closed-loop temperature regulation system through water tank insulation material, dual temperature sensors and temperature-controlled gas supply equipment; the water tank insulation design reduces heat loss, the temperature sensor in the guide tube monitors in real time, and the gas supply equipment dynamically adjusts the airflow temperature; bubble stirring enhances convection, quickly equalizes the temperature in the guide tube, avoids local temperature differences affecting the detection reaction, provides a stable environment for the specific binding of blood proteins and reagents, and improves the reliability of detection results.

[0019] 2. This application uses a conical test tube with flexible spiral blades and a bubble-driven rotation mechanism to achieve efficient solution mixing. When the bubbles rise, they adhere to the spiral blades and generate rotational force, which drives the sample, reagents and magnetic beads in the test tube to fully contact each other, avoiding uneven local concentration. This design greatly improves the coating efficiency of magnetic beads and shortens the reaction time. At the same time, the flexible spiral blades facilitate the installation and disassembly of the test tube, reduce the complexity of operation, and adapt to the needs of batch detection scenarios.

[0020] 3. The electromagnet-controlled opening and closing component of this application realizes automated sewage discharge and washing. The magnetic force adjustment makes the magnetic balls accurately gather on the inner wall of the test tube, avoiding the loss of balls or the shedding of coating due to manual operation. The negative pressure assisted sewage discharge design ensures that the solution is completely discharged and the detergent circulation cleaning is more thorough. No pipette intervention is required, reducing human error and solving the difficulties of easy damage and loss of magnetic balls in traditional washing, which significantly improves the accuracy of test results.

[0021] 4. The exhaust pipe and condenser pipe of this application form a closed-loop gas path. The condenser pipe cools the gas through a cooling plate and an interlaced plate structure, efficiently recovering moisture from the gas and returning it to the water tank, thus preventing water vapor from overflowing and polluting the environment. The dry and low-temperature airflow also cools the electromagnet, preventing it from generating heat and affecting the detection environment temperature, ensuring the stable operation of the electromagnet, reducing the impact of temperature interference on the detection results, and achieving a dual improvement in environmental protection and equipment reliability.

[0022] In summary, this application comprehensively improves the stability, efficiency, accuracy, and convenience of detection through five core advantages: precise temperature control, efficient mixing and coating, intelligent wastewater washing, closed-loop gas path design, and structural optimization. Its automated design reduces human error, and its environmentally friendly closed-loop design balances practicality and safety, making it suitable for the precise detection needs of early diagnosis of diabetic pancreatic cancer.

Detailed Implementation

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] Reference Figures 1 to 8A blood protein detection kit for early diagnosis of newly diagnosed diabetic pancreatic cancer is disclosed, which is used to detect the concentrations of PLTP, CRTAC1, and ITGAV in the blood. The kit includes a kit 1, which is divided into upper and lower layers. The upper layer has an independent placement cavity 12 in the center. The remaining parts of the upper layer form a water tank 17 around the placement cavity 12. The inner wall of the water tank 17 is lined with heat-insulating material to improve the overall heat preservation effect of the water tank 17. A temperature sensor is installed inside the water tank 17 to monitor the water temperature inside the water tank 17 to ensure that the water temperature is suitable for testing. A wastewater box 2 is movably placed in the lower layer of the kit 1 for collecting wastewater for subsequent treatment.

[0034] The reagent kit 1 has multiple guide tubes 18 located in the water tank 17 above it. The top of the guide tube 18 has a boss 110 installed on the top wall of the reagent kit 1. The boss 110 is connected to the inside of the guide tube 18. A bearing 19 is fixedly installed inside the boss 110. A test tube 3 is placed between the bearing 19 and the guide tube 18. The test tube 3 is tapered in shape and has a pressure plate on the upper side. A cap 11 is threaded to the outside of the boss 110. A sealing strip is provided between the two to ensure a sealing effect. The cap 11 acts on the pressure plate to fix the test tube 3. An annular groove is provided on the inner top wall of the cap 11. A sealing plate 111 is movably installed in the annular groove. The lower end of the sealing plate 111 is sealed with the test tube 3 by a sealing ring. A ball bearing is embedded in the top so that the sealing plate 111 can rotate with the test tube 3.

[0035] The outer surface of the test tube 3 is provided with a spiral blade 31, which is made of a flexible material, making it easier for the test tube 3 to be inserted into the bearing 19 and the guide cylinder 18. The bottom of the guide cylinder 18 is provided with a column 112, which is connected to the bottom wall of the guide cylinder 18 by the bearing 119. The top of the column 112 is provided with an inner cavity 115, and the lower end of the test tube 3 is located in the inner cavity 115 and sealed by a sealing ring. The bottom wall of the test tube 3 is provided with a connecting pipe 35 on one side. One end of the connecting pipe 35 is connected to the inner cavity 115, and the other end is connected to the inside of the guide cylinder 18, so that when the test tube 3 is inserted into the inner cavity 115, the gas in the inner cavity 115 can be discharged through the connecting pipe 35, ensuring the smooth insertion of the test tube 3.

[0036] Each guide tube 18 is equipped with a temperature sensor inside and a nozzle 114 at its bottom. The nozzle 114 is supplied with warm air by an air pipe 15. The end of the air pipe 15 away from the nozzle 114 is connected to an external air supply device. The air supply device can adjust the temperature of the output air in real time according to the data monitored by the temperature sensor. The nozzle 114 sprays air and forms a large number of bubbles in the guide tube 18. The rapid stirring of the bubbles enhances convection and quickly adjusts the temperature to ensure the balance of the monitored temperature. At the same time, the bubbles attached to the spiral blade 31 continuously rise and provide a component force to rotate the test tube 3. The solution in the test tube 3 rotates with it to ensure the mixing of the solution and improve the coating efficiency of the magnetic balls. Several air vents are opened on the upper side wall of the guide tube 18 so that the gas inside the guide tube 18 can enter the water tank 17 through the air vents.

[0037] Both the bottom wall of test tube 3 and the lower part of column 112 are equipped with vertically extending drain pipes 113 for draining the liquid in test tube 3 and inner cavity 115 into wastewater box 2. One side of drain pipe 113 is equipped with an opening and closing assembly for controlling the opening and closing of drain pipe 113. The opening and closing assembly includes a movable groove connected to drain pipe 113. A plug 32 is rotatably installed at one end of the movable groove near drain pipe 113. A slider 33 is slidably installed inside the movable groove. A spring 34 connects the end of slider 33 away from plug 32 to the inner wall of the movable groove. Slider 33 is made of magnetic material. The placement cavity 12 is equipped with a mounting frame. Electromagnets 16 are installed on multiple sides of the mounting frame. The number and position of electromagnets 16 correspond one-to-one with sliders 33, so that when electromagnets 16 are energized, they can generate attractive or repulsive forces on sliders 33, thereby driving sliders 33 to move and pushing plug 32 to rotate, thus controlling whether drain pipe 113 is opened or closed.

[0038] The top side of the water tank 17 is provided with an exhaust pipe 13 that communicates with its interior. The top of the exhaust pipe 13 is connected to a condenser pipe 14. The condenser pipe 14 is designed to be horizontally inclined. Multiple cooling plates 118 are evenly distributed on the inner top wall of the condenser pipe 14. Plate 116 and Plate 217 are distributed alternately inside the condenser pipe 14. Plate 116 is located at the bottom and has a gap between it and the bottom wall of the condenser pipe 14, so that the moisture in the gas can flow back into the water tank 17 through the gap. The end of the exhaust pipe 13 is connected to the interior of the placement cavity 12, so that the low-temperature dry gas can cool the electromagnet 16.

[0039] In this application, before the test begins, the staff fills the water tank 17 with sufficient warm water and observes the water temperature through the temperature sensor inside the water tank 17 to facilitate adjustment and ensure that the water temperature is suitable for the test. The reagent kit 1 has three sets of protrusions 110, and each protrusion 110 has a bearing 19 inside. The lower part of the test tube 3 is designed to be conical, and a spiral blade 31 is spirally provided on the outer surface of the conical shape. The spiral blade 31 is made of flexible material. During the test, the test tube 3 is installed into the protrusion 110. The flexible spiral blade 31 can easily pass through the bearing 19. The bottom of the test tube 3 has a connecting tube 35. After entering the water, the air pressed into the bottom of the test tube 3 is released through the connecting tube 35 to prevent air from entering the test tube 3 during subsequent operations such as washing, which would affect the test quality and increase the difficulty of operation. Finally, the bottom of the test tube 3 is inserted into the water. Inside the column 112, the column 112 is rotatably connected to the bottom of the water tank 17 via the bearing 119. The column 112 and the bottom of the test tube 3 are sealed by a sealing ring. During insertion, the water in the inner cavity 115 is drained through the connecting pipe 35 to ensure smooth insertion. After insertion, the cap 11 is connected to the boss 110 by threads and presses the test tube 3 firmly. The cap 11 and the boss 110 are sealed by a sealing ring. The cap 11 is equipped with a sealing plate 111. The sealing plate 111 is sealed with the test tube 3 by a sealing ring. The top of the sealing plate 111 is embedded with a ball to ensure that the sealing plate 111 can rotate with the test tube 3. During the test, the sample, reagent, magnetic ball, etc. are injected into the test tube 3 at one time for reaction. The temperature in the guide tube 18 is monitored by temperature sensors.

[0040] Each guide tube 18 is equipped with nozzles 114 evenly distributed at the bottom, and is supplied with warm air independently through air pipes 15. The nozzles 114 spray air into the guide tube 18 to form a large number of bubbles. The rapid stirring of the bubbles enhances convection and quickly regulates the temperature to ensure the balance of the monitored temperature. At the same time, the bubbles attached to the spiral blades 31 continuously rise and provide a component force to rotate the test tube 3. The solution in the test tube 3 rotates along with it to ensure the mixing of the solution and improve the coating efficiency of the magnetic balls.

[0041] Both test tube 3 and the bottom of the inner cavity 115 are equipped with identical opening and closing components. After the reaction time is reached, the operator turns on the power to the electromagnet 16 and controls the magnetic force through current. The magnetic force of the electromagnet 16 increases uniformly. Due to the influence of the ferromagnetic material, the test tube 3 and the spring 34 of the column 112 point towards the electromagnet 16. The magnetic balls are magnetically attracted and gather on the inner wall of the test tube 3 near the electromagnet 16 under the influence of the magnetic force. Through the uniformly changing magnetic field, the magnetic balls are all magnetized and have sufficient time to gather, preventing the magnetic balls that have not gathered in time from being washed away during manual washing, thus improving the accuracy of the detection. When the magnetic force reaches its maximum, the slider 33 is attracted and... The compression spring 34 and the plug 32 flip downwards. First, the water in the inner cavity 115 is discharged from the drain pipe 113 into the sewage box 2 under its own weight. Then, under the influence of the negative pressure in the inner cavity 115, the solution in the test tube 3 is smoothly discharged. The staff continuously adds detergent to carry out the washing operation. The operation is simple and convenient. At the same time, it avoids the accidental contact of the pipette with the magnetic ball during conventional washing, which may cause the magnetic ball to fall off and be washed away, or cause the coating on the surface of the magnetic ball to fall off, thus affecting the accuracy of the test results. After a period of time, the power is turned off to demagnetize the electromagnet 16. The rotation of the test tube 3 ensures the mixing and cleaning of the washing solution. Then the power is turned on again to repeat the operation to complete the washing, ensuring that the washing is thorough and improving the accuracy of the results.

[0042] Bubbles rise and gather at the top of water tank 17. The gathered gas is discharged through exhaust pipe 13 to ensure stable internal pressure in water tank 17. Plate 2 117 and Plate 1 116 are evenly distributed inside the condenser tube 14. After the airflow enters the condenser tube 14, it flows up and down continuously to enhance convection and is cooled by the cooling plate 118 at the top. As the temperature decreases, the moisture contained in the gas condenses and gathers at the bottom of the condenser tube 14. The bottom of Plate 1 116 has an opening to facilitate water flow. Finally, the water flows back into water tank 17 along the inclined exhaust pipe 13, ensuring the airflow is dry and preventing water vapor from overflowing and polluting the external environment. Finally, the dry and low-temperature airflow is ejected from the placement chamber 12 and carries away the heat generated by electromagnet 16, ensuring the normal operation of electromagnet 16 and reducing the impact of temperature on the results, thus improving the accuracy of the results. After all operations are completed, the pressure cap 11 is unscrewed and the test tube 3 is removed and sent to a professional instrument for structural testing.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
