Objective To explore the correlation between the need for cognitive closure and the way of coping with the disease in patients with hepatitis B cirrhosis. Methods 217 patients with hepatitis B cirrhosis were questionnaired by the Need for Cognitive Closure Scale and the Medical Coping Style Questionnaire (Chinese version). Results The total score of need for cognitive closure in separation and conversion disorder patients was (217.65 ± 31.23) points. The scores of face, yield and avoidance in the coping style were respectively (18.87±2.49) points,(13.21±1.53) points and (17.63±2.27) points. The score of face was significantly negatively correlated with the total score and all dimension scores of the need for cognitive closure(r=-0.421,-0.387,-0.405, P<0.05);the scores of yield and avoidance were positively correlated with the total score and all dimension scores of the need for cognitive closure (r=0.343-0.432, P<0.05). There were significant difference of the way of coping with the disease in the patients with different family income, payment method, course of disease (t=-3.080-3.490, P<0.05). Multiple regression analysis showed need for cognitive closure was influencing factor of way of coping with the disease in patients with hepatitis B cirrhosis. Conclusions The level of need for cognitive closure is in the high level in patients with hepatitis B cirrhosis, and influencing the way of coping with the disease.

A kind of personal computer-based monitoring system with piezoelectric sensor for pulse signal is developed,which constitutes with single-chip microcomputer AT89S52 and personal computer. The integrated polyvinylidene difluoride piezoelectric pulse sensor is used to pick up the pulse signals of examined person and transfer to electric signal under processing. The weak signal from the sensor is enlarged through three-operation-amplifier circuit. The magnified pulse signal is converted digital pulse signal through ADC0809 chip and the pulse number can directly show on LED tubes through the coding circuit. At the same time the digitalized pulse signal is delivered to personal computer through serial communication interface of single-chip microcomputer AT89S52 and personal computer under RS-232-C serial communication interface protocol. The pulse signal is then shown,recorded,saved and processed through computer software. The single-chip microcomputer AT89S52 circuit controls the collection and enlargement of the original signal and communicated with personal computer. When the single-chip microcomputer part is not connected with computer under serial communication interface,it becomes an improved portable electronic pulsometer and can be taken conveniently and show pulse number.
