OBJECTIVE:To observe the effect of cinepazide maleate combined with Xueshuantong injection on the blood sup-ply of subcutaneous artery after flap transplantation. METHODS:68 patients with cross-regional combined with flap transplantation in extremity soft tissue injury were randomly divided into observation group and control group. The roast lamp irradiation in the flap transplantation and ambulation prohibited,alcohol and tobacco prohibited were carried out as rountine treatment. On this basis, control group was treated with cephalosporins,papaverine and low molecular dextran after flap transplantation. Observation group was treated with cinepazide maleate 8 ml adding into 0.9% Sodium chloride injection 250 ml by intravenous infusion,once a day+Xueshuantong injection 5 ml adding into 0.9% Sodium chloride injection 250 ml by intravenous infusion,once a day. The course for both was 14 d. The clinic data was observed,including blood rheological indicators (whole blood high cut,whole blood cut, whole blood low cut,plasma viscosity and RBC aggregation index),and coagulation function indicators [thrombin time(TT),acti-vated partial thromboplastin time(APTT),prothrombin time(PT)and GB normalized ratio(INR)] before and after 1,3 and 7 d of surgery,and the postoperative incidence of arterial vascular crisis within 7 d and adverse reactions. RESULTS:There was no sig-nificant difference in the incidence of arterial vascular crisis in 2 groups after 1 and 2 d of surgery(P>0.05);the incidence of arte-rial vascular crisis in 3,4,5,6 and 7 d in observation group was significantly lower than control group,with significant difference (P<0.05). After 3 and 7 d of surgery,blood rheological indicators and 1,3 and 7 d of coagulation function indicators in 2 groups were significantly better than before,and observation group was better than control group,with significant difference(P<0.05). There were no significant difference in the incidence of adverse reactions between 2 groups(P>0.05). CONCLUSIONS:Cinepa-zide maleate combined with Xueshuantong injection can effectively improve the blood rheological indicators and coagulation func-tion indicators of patients,reduce the incidence of arterial vascular crisis,with good safety.

Aiming to the fact that the distribution modules of the C3I simulation system originally developed based on TCP/IP protocol has to be compatible with the present HLA (High Level of Architecture) rules, three methods for implementing the interaction of HLA and TCP/IP subsystems are presented to make the original TCP/IP modules directly used in the HLA-based C3I system without redevelopment. The three methods are agent method, middleware method and gateway method. Moreover, the implementation of gateway method via VC++ as well as the key technology is discussed.

Objective To investigate the significance of procalcitonin (PCT) and C-reactive protein (CRP) in the early diagnosis of sepsis in patients with percutaneous nephrolithotomy (PCNL). Methods One hundred and ninety-eight patients who had underwent PCNL were divided into sepsis group (148 cases) and control group (50 cases). The PCT and CRP 6 h before and after operation were compared between 2 groups, and the receiver operating characteristic curve was drawn. The area under curve (AUC), optimal diagnostic boundary value, susceptibility and specificity were calculated. Results The PCT and CRP before operation in sepsis group were significantly higher than those in control group:(3.911 ± 2.011) ng/L vs. (1.353 ± 0.311) ng/L and (54.85 ± 8.75) g/L vs. (38.65 ± 10.76) g/L, and there were statistical differences (P<0.01). The AUC of PCT was 0.974, and the AUC of CRP was 0.853. The optimal diagnostic boundary value of PCT was > 1.65 ng/L, and the susceptibility and specificity were 97.91% and 91.01%; the optimal diagnostic boundary value of CRP was > 43.54 g/L, and the susceptibility and specificity group were 93.51% and 79.21%. Conclusions For patients with sepsis after PCNL, PCT is more significant than CRP for early diagnosis. PCT detection can be used as an important auxiliary examination for clinical diagnosis of sepsis, which could help clinicians to detect and treat the sepsis early and can greatly improve the survival rate of patients.

Objective: To investigate the implementation of disease prevention and control services at tertiary public general hospitals in Beijing for providing evidences to explore and build a scientific evaluation model of disease control service in medical institutions. Methods: June to September 2018, through a questionnaire survey of 50 tertiary public general hospitals in Beijing, a descriptive analysis was made on the department setting, personnel allocation and service provision status of disease prevention and control at tertiary public general hospitals in Beijing. Results: Among the 44 investigated public tertiary general hospitals, 26(59.1%) medical institutions have set up departments of disease prevention and control. The average staffing of 44 hospitals was 5.8 persons for the department. Professional composition of the staff was mostly nursing and clinical disciplines, and the academic and professional titles were mostly undergraduate and intermediate degrees respectively. Overall performance of disease prevention and control services in public tertiary general hospitals was satisfactory. The work was well carried out in communicable disease control and death-surveillance management, namely in immunoprophylaxis, chronic noncommunicable diseases and injury monitoring, which varies widely in mental health services, occupational health management, environmental and health monitoring and other functions. Conclusions Professional ability and management level of personnel still need to be improved. We should further clarify the joint prevention and control mechanism of the " Three-in-one" nature of disease control institutions, medical institutions and communities, promote the combination of medical treatment and prevention, and explore the classification and grading evaluation of disease control work based on the types and quantity requirements of disease prevention and control services undertaken by hospitals, so as to effectively improve the level of disease control services in hospitals.
