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.

Objective Liver is a common site of metastasis of gastric cancer and hitherto there has been no uniform treatment for liver metastasis of gastric cancer. This study was to investigate the clinical characteristics and prognostic factors of liver metastasis of gastric cancer in order to provide some evidence for the improvement of the diagnosis and treatment of the disease. Methods We ret-rospectively analyzed the clinical characteristics and survival data of 143 patients with liver metastasis of gastric cancer treated in our hospital between March 2007 and September 2012. We investigated the independent risk factors affecting the prognosis of the disease u-sing the Cox Regression Model. Results Seventy-five ( 52. 4%) of the 143 patients survived for 12 months, 41 ( 28. 7%) for 24 months, and 18 (12.6%) for 36 months, with a median survival time of 14 months. Univariate analysis revealed statistically significant differences in the survival time among the patients with different histological grades of primary gastric cancer, time of liver metastasis, types of metastatic liver cancer, extra-liver metastasis, and treatment methods ( P<0.05) . Multivariate Cox regression analysis showed the histological grade of gastric cancer to be low-or non-differentiation ( HR=2.67, 95% CI:1.51-4.72) and the type of liver meta-static cancer to be H2 ( HR=1.89, 95% CI:1.08-3.29) or H3 ( HR=2.13, 95% CI:1.32-3.44) , which were independent risk fac-tors affecting the prognosis of liver metastasis of gastric cancer, while palliative chemotherapy ( HR=0.55, 95% CI:0.32-0.95) was an independent protective factor of its prognosis. Conclusion Patients with liver metastasis from gastric cancer usually have a poor prognosis, especially those with histologically low-grade gastric cancer or type-H2 or -H3 liver metastatic cancer. The prognosis of thepatients undergoing palliative chemotherapy may have a better prognosis than those receiving best supportive care. A comprehensive therapy should be recommended to patients with liver metastasis from gastric cancer.

OBJECTIVE:To investigate the effects of atorvastatin combined with valsartan on efficacy,safety and related indi-cators in patients with chronic nephritis. METHODS:86 patients with chronic nephritis were randomly divided into control group (43 cases)and observation group(43 cases). All patients were given low-salt,low-protein and high-quality diet with protein intake of 0.8 g/(kg·d),appropriately given Cyclophosphamide tablet,Prednisone tablet,Penicillin V potassium tablet and other conven-tional treatment. Based on it,control group was given 160 mg valsartan,once a day in early morning. Observation group was addi-tionally given 20 mg atorvastatin,once a day before bedtime. They were treated for 6 months. Clinical efficacy,24 h protein amount (24 h pro),serum creatinine (Scr),blood urea nitrogen (BUN),glomerular filtration rate (GFR),C-reactive protein (CRP),total cholesterol (TC),triglyceride (TG ),low density lipoprotein (LDL) and high density lipoprotein (HDL) in 2 groups were observed,and incidence of adverse reactions was followed-up for 9 months. RESULTS:The total effective rate in ob-servation group was significantly higher than control group,the difference was statistically significant(P<0.05). Before treatment, there were no significant differences in 24 h pro,Scr,BUN,GFR,CRP,TC,TG,LDL and HDL between 2 groups(P>0.05). After treatment,24 h pro,Scr,BUN and CRP in 2 groups were significantly lower than before,and observation group was lower than control group,GFR was significantly higher than before,and observation group was higher than control group,the differenc-es were statistically significant(P<0.05). TC and LDL in 2 groups were significantly lower than before,HDL was higher than be-fore,the differences were statistically significant(P<0.05);but there were no significant differences in the TG between 2 groups and before and after treatment(P>0.05). And there was no significant differences in the incidence of adverse reactions between 2 groups (P>0.05). CONCLUSIONS:Based on the conventional treatment,the efficacy of atorvastatin combined with valsartan is superior to valsartan alone in the treatment of chronic nephritis,and it can significantly improve renal functions,with similar short-term safety.
