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 simple portable electronic pulsometer based on piezoelectric sensor is designed, which constituted with single-chip microcomputer AT89S51. The piezoelectric sensor is used to transform pulse beating into electrical signal. Because the signal is very weak, the regular pulse profile is only obtained after enlargement and reshaping. Three-operation-amplifier circuit is used to magnify the weak signal from sensor, and the one-order low-pass filter is used to reshape the signal to get rid of miscellaneous signals. After timing and counting by the single-chip microcomputer, the pulse number is directly shown on light-emitting diode tubes through decoding circuit. The norm time generation circuit, a single steady trigger consisted of 555 integrated circuit chip mainly, set the standard time. The single-chip microcomputer AT89S51 circuit control the enlargement and reshaping of the original signal and time trigger. This portable electronic pulsometer has many advantages, such as simple structure, steady and reliable working, direct number display, low error (

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.

An universal serial bus (USB)-based high-speed real-time pulse signal detecting system is developed. The hardware and application software of the system is presented. The integrated polyvinylidene difluoride (PVDF) piezoelectric pulse sensor is used to pick-up the pulse signals of examined person and turn to the electric signal under processing. Because the signal is very weak, only after passing through the enlargement can the regular pulse profile be allowed to be obtained. The in-phase amplifier circuit is used to magnify the weak signal from the sensor. The magnified pulse signal is converted digital pulse signal through system-on-chip single-chip microcomputer C8051F130. The digitalized pulse signal is delivered to personal computer under USB interface protocol. The pulse signal is then shown, recorded, saved and processed through computer software. This inspecting system for pulse signal has many advantages, such as its structure is simple, it works steadily and reliably, its low cost, high application value and it can also realize rapid collection and storage of pulse signal.

A newly developed production machine was introduced, which was used to produce radioisotope capsule for medical treatment. The machine can produce radioisotope capsule at different dose for treating different patients. Also, the machine can do real time detection to the production and automatically record information during production. The exploitation of the equipment avoids the side effects of using liquor radioisotope.

BACKGROUND: The recovery of activity of daily living (ADL) in hemiplegic patient is related to the recovery of motor function to certain extent. But the correlation between two aspects has not been determined yet over the past study.OBJECTIVE: To probe into the correlation between the motor function of upper and lower limbs and ADL of hemiplegic patients after cerebral apoplexy.DESIGN: Case analysis.SETTING: Department of Rehabilitation of First Affiliated Hospital of Nanjing Medical University.PARTICIPANTS: Thirty cases of hemiplegia of cerebral apoplexy were selected from inpatients of Department of Rehabilitation of Jiangsu People's Hospital from August 2002 to June 2003, of which, 20 cases were male and 10 cases were female, aged varied from 39 to 76 years.METHODS: Simplified Fugl-Meyer assessment of motor recovery (FMA)was used to evaluate the motor function of patient. Modified Barthel index assessment was used to evaluate ADL.MAIN OUTCOME MEASURES:① Simplified Fugl-Meyer assessment and modified Barthel index assessment.② Correlation between the motor function and ADL of hemiplegic patients after cerebral apoplexy.RESULTS: All of 30 cases entered result analysis.①The average result of general FMA was 40.96±32.04.The average result of motor function of upper limb was 21.78±22.87 and of low limb was 18.43±10.29.The average result of modified Barthel index assessment was 39.46±25.94. ② The correlative coefficient of general FMA and modified Barthel index assessment was 0.65, in which, the correlative coefficient of upper limb assessment and modified Barthel index assessment was 0.62 and that of lower limb assessment was 0.61.CONCLUSION: A certain correlation presents between motor function and ADL in hemiplegic patient and the influences of upper and lower limb motor functions are almost same to daily life activity.

In recent years,it has been reported that the osteopontin attracts great attention for its roles in tumor growth and metastasis.In many tumors,osteopontin plays an important role in promoting tumor growth,metastasis and enhancing adhesion and migration abilities.In particular,in hepatocellular carcinoma,osteopontin has very satisfactory sensitivity and specificity in early diagnosis and is relatively effective on prognosis prediction.Suppression osteopontin expression will inhibit liver cancer growth and metastasis,indicating that the osteopontin stays a new target for liver cancer treatment and possesses intangible clinical potential.
