OBJECTIVE:To study the implementation of scoring diseases payment under the control of total budget in some ar-eas of China,and provide reference for the further improvement of the payment. METHODS:Based on the operation process of scoring disease payment in the control of toal budget,the specific practices of Huaian,Nanchang,Zhongshan and Taiwan area, were compared. RESULTS:It showed differences in the control and allocation of total budget,the establishment of scoring diseas-es,the setup of adjustment coefficient,the development of balance methods,the complementary mechanism and the monitor exami-nation setting. CONCLUSIONS:Whether to classify the diseases according to diagnosis and treatment methods,how to setup ad-justment coefficient appropriately,how to reimburse the patients in stages and how to strengthen supervision are worthy of further thinking and exploring.

AIM: To investigate the expression of TNF-?, TGF-? in patients with oral lichen planus (OLP) and normal oral mucosa (NOM). METHODS: An immunohistochemical technique was performed to detect TNF-?, TGF-?_1 and TGF-?_2 expression in 22 cases with OLP and 10 normal controls. RESULTS: In lamina propria of OLP, the expression of TNF-? and TGF-?_1 were increased, whereas TGF-?_2 did changed significantly compared with control group. TNF-? positive signal were mostly found in macrophages, lymphocytes. TGF-?_1 positive cell was present in macrophages, endothelial cells and fibrocytes. CONCLUSION: TNF-? and TGF-?_1 play an important role in the development and maintenance of OLP local inflammation.

Objective: In order to evaluate the effect of catastrophic disease medical assistance policy in Qingdao and provide suggestions for Qingdao policy reform.Methods: This paper selects NSCLC and liver cancer as the typical deceases to analyze the effects of the policy on patients and medical insurance institutions and finally evaluate the effect of the policy.Results: results shows that after the implementation of special medicines and special medical equipment assistance, the rate of co-paying patients decreased 40.57%, and the pressure on medical insurance institutions' expenditure was significantly reduced;while after the implementation of large cost assistance, but rate of co-paying patients only decreased 7.13%, and the pressure on medical insurance institutions' expenditure was not effectively alleviated.Conclusions: Therefore, the policy not only protects patients with catastrophic disease by greatly reducing their medical burdens, but it also achieves the fine management of medical insurance fund and increases the efficiency of the fund.
4.Detector efficiency for non-helical trajectory of cone beam reconstruction.
Journal of Biomedical Engineering 2009;26(1):59-62
Using the present cone beam reconstruction formula for general trajectory, we have investigated the issue of detector efficiency for non-helical trajectory. The results reveal that the two factors dominating the detector efficiency are detector geometry and filtering directions. The methods for to higher detector efficiency are proposed, and the reliability and feasibility are tested by simulation results.

Objective To explore the clinical value of wave intensity(WI) curve of the carotid artery in patients with thyroid diseases and its value in evaluating cardiovascular function. Methods All 85 patients with thyroid diseases,including 45 hyperthyroidism and 40 hypothyroidism, were enrolled as case groups,while 270 healthy volunteers were considered as control. All the case groups and control were taken WI test under quiescent condition,and six continuous curves of the carotid artery diameter changes were recorded.Then the parameters of accelerating wave intensity (W1), decelerating wave intensity ( W2), negative area (NA) ,corrected R-W1 and W1-W2,elasticity modulus(Eρ) ,stiffness index(β) ,arterial compliance(AC) and pluse wave velocity(PWV) were calculated. Relationship between those indices and FT3 ,FT4 and TSH were analyzed by Pearson correlative analysis. Results The WI curve appeared differently among different groups,but the vessel elasticity indices did not have statistical significance. Correlation only existed between FT3 and part of the WI parameters. FT3 positively correlated with W1 ( r = 0. 951, P <0.01 ), NA( r =0.813, P <0.01) and W1-W2' ( r = 0. 887, P <0.01 ). And R-W1 ' negatively correlated with FT3( r =-0.878, P <0.01 ). Conclusions The WI curve could represent different function status of thyroid,and could be considered as a noninvasive examination for further clinical research,which may help explain the corresponding cardiovascular changes.

Objective To summarize the characteristics of common carotid arterial wave intensity (WI) in healthy volunteers and offer the normal reference values of WI. Methods Common carotid arteries (CCA) in 525 healthy volunteers were examined using Aloka Prosound α10 equipped with wave intensity software. The volunteers were divided into six group according to age,group A,<20 years old;group B,20 - 29 years old;group C,30 - 39 years old;group D,40 - 49 years old;group E,50 - 59 years old and group F,≥60 years old. Carotid arterial wave intensity in normal subjects had two positive peaks, the first peak,W1 ,and the second peak, W2. Between the two positive peaks, a negative area (NA), the time interval between the R-wave of ECG and the first peak(R-W1 ) and that between the first and second peaks (W1-W2) were observed. Results ① 1050 common carotid arteries in 525 volunteers were studied. The mean values of W1,W2,NA,R-W1,and W1-W2 were (8332±4796) mmHg · m-1 · s-3,(1853±1143)mmHg · m-1 · s-3,(38 ± 26) mmHg · m-1 · s-2, (102 ± 19)ms and (266 ± 42)ms,respectively. ②These values were no significant between the left and right CCA in same group. W1 and NA were correlated with age ( r = - 0. 204 and r = -0.301, P <0. 001). W1 and NA in group A and B were significant increased than those in other groups( P <0. 05 or P <0. 001 ). ③There were statistical significances in W1 and W1-W2 of CCA between male and female. ④There were no statistical significances in all values in common carotid arteries of both sides (P >0. 05). ConclusionsWI technique is useful for evaluating the dynamic behavior of the heart and the vascular system and their interaction. W1 is very sensitive to the changes in the working condition of the cardiovascular system.

Objective:
To investigate the etiology, clinical features, treatment and outcome of nephrotic syndrome associated with chronic mercury poisoning.
Methods:
From June 2013 to April 2018, Beijing Chaoyang Hospital, Capital Medical University received 33 patients with chronic mercury-neutral nephrotic syndrome. The clinical manifestations, laboratory tests, treatment methods, and outcomes were analyzed.
Results:
Among the 33 patients, 27 patients had mercury exposure due to daily-life contact and the other 6 patients were caused by iatrogenic mercury. The symptom was characterized by typical nephrotic syndrome such as lower extremity edema and proteinuria at first onset. The treatment was based on mercury-removing treatment, 19 cases were treated with mercury removal alone, 16 cases were completely relieved; 10 cases were treated with mercury removal and glucocorticoids, all of which were completely relieved; 4 cases were treated with mercury removal, glucocorticoids and immunosuppressive agents, all complete remission; clinical complete remission rate is about 90.9% (30 cases in total) . Urinary mercury levels decreased the fastest between the first and second courses of mercury treatment, but the total amount of urine protein increased. As the amount of urinary mercury excreted increased, the total amount of urine protein decreased gradually (

The aim of this study is to evaluate the effectiveness of a smart non-invasive blood glucose monitor prototype during pregnancy through clinical validation.The monitor utilizes near-infrared spectroscopy combined with AI big data analysis of photoelectric volumetric pulse wave data to achieve non-invasive monitoring of blood glucose in women during pregnancy.The research team developed a monitor that employs a sensing chip,effectively overcoming the problems of weak signals and individual differences in non-invasive blood glucose monitoring.The user experience is enhanced by visualizing the test results on the accompanying cell phone APP(application)of the smart non-invasive pregnancy blood glucose monitor.Clinical validation revealed that the non-invasive monitoring data for pregnant women aged 20~30 years significantly differed from those obtained via traditional blood glucose measurement methods,whereas no significant difference(P<0.05)was observed for pregnant women aged 31~42 years.The study concluded that further calibration of the monitor and an expansion of the sample size are necessary to enhance consistency with invasive glucose monitoring results.
