Chinese Journal of Medical Instrumentation 2014;38(1):30-32
To meet the demands of high definition of video and transmission at real-time during the surgery of endoscope, this paper designs an HD mobile video transmission system. This system uses H.264/AVC to encode the original video data and transports it in the network by RTP/RTCP protocol. Meanwhile, the system implements a stable video transmission in portable terminals (such as tablet PCs, mobile phones) under the 3G mobile network. The test result verifies the strong repair ability and stability under the conditions of low bandwidth, high packet loss rate, and high delay and shows a high practical value.

Modern Clinical Nursing 2017;16(5):51-55
Objective To explore the effect of the health education with teaching -back method on senior citizens' hypertension related health literacy in nursing homes. Methods Six nursing homes, randomly selected using stratified cluster random sampling method, were randomly divided into the experiment group and the control group,151 cases in each group. The control group received peer education method, and the experiment group received the health education with teaching-back method on the basis of the control group. The hypertension related health literacy total scores and 4 dimension scores of the two groups were compared before and after the intervention. Results There was no significant difference in the total score and each dimension score of the hypertension related health literacy between the experiment group and the control one before intervention (P>0.05). There was significant difference in the total score and each dimension score of the hypertension related health literacy between the experiment group and the control one after intervention (P<0.001). The total score and each dimension score of the hypertension related health literacy of the experiment group were significantly higher than that of the control group. There was significant difference in the total score and each dimension score of the experiment group before and after intervention (P<0.001). The scores of the experiment group after intervention were significantly higher than before. There was significant difference in the total score, knowledge attainment score, faith accomplishment score and technical accomplishment score of the control group before and after intervention (P < 0.01). The score of the control group after intervention were significantly higher than before. But the behavior literacy before and after intervention was not statistically significant (P>0.05). Conclusion The health education with teaching-back method can improve the elderly hypertension related health literacy level and improve the quality of health education.
5.Analysis of the relationship between serum HBV-DNA And hepatic fibrosis
International Journal of Laboratory Medicine 2015;(3):326-327,330
Objective To analyze the relationship between serum HBV-DNA and hepatic fibrosis in patients with hepatitis B. Methods Serum HBV-DNA load and hepatic fibrosis hyaluronic acid (HA),Ⅲ procollagen N terminal peptide(PⅢNP),laminin (LN),Ⅳ collagen(Ⅳ-C)of 154 cases were detected by real-time fluorescence quantitative PCR and chemiluminescence method. Statistical analysis of the correlation between HBV-DNA load and hepatic fibrosis indicator was performed.Results The data of HBV-DNA load after taking lg value was 5.49±1.39;The serum concentration of hepatic fibrosis HA was (166.95±148.20)ng/mL,PⅢNP was (12.14±7.37)ng/mL,Ⅳ-C was (65.29±45.48)ng/mL,LN was (59.52±35.67)ng/mL.The difference between experimental group and control group in hepatic fibrosis was significant(P <0.05).Serum HBV-DNA only correlated with LN(r=0.284,P =0.015).Conclusion There is no significant correlation between serum HBV-DNA and hepatic fibrosis in hepatitis B pa-tients.Anti-fibrosis treatment should also be strengthened for hepatitis B patients in the course of antiviral treatment.
6.Influence of TAMs on monocyte chemoattractant protein-1 and macrophage inflammatory protein-1 in NSCLC
Chinese Journal of Primary Medicine and Pharmacy 2008;15(5):796-798
Objective To observe cocultured TAMs cell U937 and NSCLC cell A549 effecting on MCP-1, MIP-1 expression under different conditions in vitro. Methods The cell UM937 of different concentrations (0,1,2,4,8×105/ml) was respectively selected to coculture with the cell A549 0f certain concentration (1.0×105/ml) for 24 hours, in situ hybridization was carried out to detect MCP-1, MIP-1mRNA positive expressions in cell A549 of every concentration group. Under the condition that both concentrations of cell A549 and cell U937 are l.0×105/ml, the same method was used to measure MCP-1, MIP-1mRNA positive expressions in cell A549 in different periods (4h, 8h, 16h, 32h, 48h). Results The positive expression ratios of MCP-1, MIP-1mRNA in cell A549 significantly increased along with addition of the cell U937 concentration and delay of the cocultural time, apparently higher than that of primary cocultured group that the cell U937 was 0×105/ml and that of contrast group at every period (all P<0.05). Conclusion The mutual interaction between TAMs and NSCLC cells has closely positive correlation with MCP-1, MIP-1mRNA positive expressions in cell A549, and depends on cocultural concentration and time.
8.The Cost-Effectiveness Analysis of Irbesartan in the Treatment of Hypertensive Type 2 Diabetic Patients with Microalbuminuria in China
China Pharmacy 1991;0(03):-
OBJECTIVE:To evaluate the cumulative incidence of end-stage renal disease(ESRD)in Chinese hypertensive type2diabetic patients with microalbuminuria(DHM)treated with different regimes,and to provide reference for decision makers.METHODS:A peer-reviewed Markov model that simulated progression from microalbuminuria to nephropathy,dou?bling of serum creatinine,ESRD,and all-cause mortality in patients with DHM was adapted to China.Three strategies were compared:(1)early use of irbesartan(i.e.prompt treatment in subjects with microalbuminuria);(2)late use of irebesartan(i.e.as from overt nephropathy);(3)standard hypertension care(with comparable blood pressure control).Cumulative incidence of ESRD,costs and life expectancy were projected for a hypothetical cohort of1000subjects.Treatment-specific progression and mortality probabilities were derived from published trials:IRMA-2(in microalbuminuria)and IDNT(in overt nephropathy).Medical management and cost data per state were obtained from published local sources.A flexible time horizon up to25years and third party payer perspective were used.Future costs and LE were discounted at3%yearly.RESULTS:When compared with standard blood pressure control,early use of irbesartan was evaluated to reduce the cumulative incidence of ESRD from(mean?standard deviation)8%to22%,save RMB30348(US$3667),and add0.638life years per treated patient.Late use of irbesartan was dominant over control group but dominated by early irbesartan.Break-even occurred after13years.CON?CLUSION:Treating DHM patients by early use of irbesartan is evaluated to reduce the incidence of ESRD,extend life and reduce costs.Treating patients at a later stage is still beneficial,however to a lower extent.
9.The clinical value of thrombelastography in diagnosis and treatment of acute traumatic coagulopathy
Chinese Journal of Emergency Medicine 2016;25(8):1082-1086
Acute traumatic coagulopathy (ATC) is one of coagulopathy induced by severe trauma in the early phase of trauma.It is always with high morbidity,mortality and multiple organ failure.Early diagnosis and treatment is the main content of trauma surgery in the department of emergency and the key to reduce mortality.Thrombelastography (TEG) can comprehensively assess the different stages of coagulation,early diagnose disturbance of blood coagulation and guide the goal-directed therapy with low complications,mortality and medical costs.TEG has been widely used in the operation of cardiac surgery,liver transplantation and trauma surgery to monitor coagulation and guide therapy.This paper mainly reviews the clinical value of thrombelastography in diagnosis and treatment of acute traumatic coagulopathy.
