ABSTRACT
Pancreatic duct stone is a sequel of chronic pancreatitis and may be found in the main ducts,side branches or parenchyma.These stones obstruct the pancreatic ducts and produce ductal hypertension,which leads to pain,the cardinal feature of CP.Surgical operation has been the preferred treatment of pancreatic duct stones in many domestic and external pancreatic medical centers.Lithotomy by longitudinal pancreatic duct incision and Roux-en-Y anastomosis of pancreatic duct to jejunum is the main and effective surgical procedure,while micro-surgery was also rational for the treatment of pancreatic duct stones.However,further studies with a larger sample size and longer follow-up duration are needed to improve the surgical technique and verify our initial results.
ABSTRACT
To develop intelligent informatized system for the quality control of ECG monitor. Based on the platform of PowerBuilder and SQL Server and using scientific management process as the standard, the informa-tized system was developed to cover all aspects of ECG monitor quality control. This informatized system, which closely accorded with related laws and regulations, had graded authority, clear responsibilities, multi functions and easy operation. Computer information technology plays an important role in scientific management system of ECG monitor quality control.
ABSTRACT
Objective To design a set of quality control management platform of ECG monitor in order to evaluate the quality of ECG monitor quickly and objectively and monitor and record the whole course of quality control.Methods The quality control platform was designed with the existing ECG monitor quality control methods, the existing detection devices, database technique and digital recognition technique based on neural network.Results The platform could be used for the intelligent data acquisition, data recognition, data analysis and statistics of ECG monitor quality control.Conclusion The platform may enhance the quality control of ECG monitor greatly.
ABSTRACT
Objective:To investigate the feasibility of hemodialysis machine preventive maintenance model of based on quality control detection.Methods: Selected sample of 32 hemodialysis machines of two major imported brands, 16 of them using the traditional preventive maintenance mode for maintenance, and the other 16 sets of quality control detection based preventive maintenance hemodialysis machine maintenance mode. That: by use of HDM99XP detector instrument for testing the five hemodialysis machine main indicators, maintenance cycle is 16 weeks, and then the equipment failure rate indicators of two modes of preventive maintenance were compared.Results: The hemodialysis machine preventive maintenance model of based on quality control detection rise superior to the traditional maintenance mode in lower failure rate, quantitative, objective, and less affected by human factors.Conclusion: The hemodialysis machine preventive maintenance model of based on quality control detection was better than the traditional preventive maintenance mode,also a promising preventive maintenance mode.
ABSTRACT
OBJECTIVE@#To localize and define the region of nucleus export signal (NES) on BRD7, and determine the role of this region in nucleus export of the external protein.@*METHODS@#Based on an in vitro expressed model of green fluorescence protein (GFP), we performed DNA walking analysis to set BRD7 into several sections according to the structural characteristics of BRD7, investigated the effect of different sections of BRD7 on nucleus export of GFP, defined the region of nucleus export signal sequence of BRD7, and further ascertained the content of amino acids in BRD7 and potential localization of BRD7 NES by bioinformatics.@*RESULTS@#B7C1 fragments ranged from aa219 to aa450 in BRD7 were found to target the external protein GFP into the cytoplasm detected by GFP direct fluorescence, which could be inhibited by NES inhibitor Leptomycin B (LMB). This region was rich in hydrophobic amino acid residues but no typical NES with characteristics of leucine-rich sequence by bioinformatics.@*CONCLUSION@#The region from aa219 to aa450 is primarily defined as an atypical NES in BRD7.

ABSTRACT
Objective To establish quality control system for medical equipment to ensure its application safety and quality. Methods All aspects of medical equipment management were analyzed. Results All aspects of medical equipment management had to be paid attention to. Conclusion Keeping Improved quality of medical equipment contributes to the decrease of the doctor-patient dispute.
ABSTRACT
Quality control of medical equipment is very important to the diagnostic accuracy and the cure effect. The work of the quality control is the main technical basis of the hospital construction in promoting medical development, and it's also an important content of the modem medical management. The status, causes and countermeasures of medical equipment quality control in military hospital at the present time are analyzed and discussed.
ABSTRACT
Wavelet transforms are used in detecting ECG characteristic points recognition.The relationships between ECG characteristic points and the modulus maximum pairs of their wavelet transfoms are expounded.The application perspective of wavelet transforms to ECG characteristic points recognition is predicted through the analysis of the results.
