In the light of requirements of medical equipment simulation system, the overall framework of joint control system of medical equipment integrated support in the theater is designed in this paper. Such modules are developed with Delphi as communication module, module for equipment basic information, module for equipment video information and module for medical faculty information. A joint control system suiting integrated support simulation sand table for medical equipment is complteted,which provides a multidimensional informational platform for integrated demonstration of medical equipment.

Objective To investigate parameter changes for skin aging in murine model induced by D-galactose. Methods Sixty 3-month-old female mice were randomly divided into three groups: normal control group,low dose (80 mg/kg)and high dose (1000 mg/kg) D-galactose groups. After subcutaneous administration for 6 weeks, the aging models were established. Then, histochemical standards relating to aging were measured and morphologic alterations of surplus dorsal skin were observed under microscope and analyzed. Results In contrast with the control group, high dose D-galactose group showed that the thickness of dermis (624.5 ?48.5) ?m was significantly reduced (P

Objective To study the effects of sodium bicarbonate (SB) on resuscitation in swine model of asphyxiation cardiac arrest (CA).Methods Thirty-two healthy miniature pigs were randomized (ramdom number) into two groups,the SB group (n =16) and the control group (n =16).Animals in both groups underwent endotracheal tube clamping to induce CA.Once induced,CA left untreated for a period of 8 minutes.At the beginning of initiation of cardiopulmonary resuscitation (CPR),SB (1.0 mEq/kg,diluted to 40 mL) was injected in central venous in SB group and isopyknic normal saline solution was injected in control group.Two minutes following initiation of CPR,defibrillation was attempted until return of spontaneous circulation (ROSC) was achieved or animals died.To assess the SB effects on myocardial metabolism,positron emission tomography (PET) was performed at baseline and 6 after ROSC.To analyze 18F-FDG myocardial uptake identified in PET,the maximum standardized uptake value (SUV) was measured.Results ROSC was 10/16 successful in SB group and only 8/16 successful in control group.The average survival time of SB group was (3.63 ± 0.76) h and that of control group was (2.45 0.70) h.Myocardial metabolism imaging using PET demonstrated that myocardial metabolism injuries in control group were more severe than in SB group at 6 h after ROSC and SUVmax was more higher in SB group than in control group (6 hrs after ROSC:1.32 ± 0.20 vs.1.10 ± 0.14,P =0.035).Conclusions In swine model of asphyxiation CA,SB improve the myocardial metabolism and might raise the possibility of ROSC and have no hypernatronemia.

OBJECTIVE:To select a technique for preparation of fluconazole for injection and to establish a method for determination of its content.METHODS:The formula was selected on the basis of pH value and species of solution adjuvant.The content was determined by HPLC.RESULTS:The preparation was stable when pH value was between6.5～8.5,and its clarity could be increased by propylene glycol.The detectable concentration of fluconazole showed a good linear correlation in the range of40～200?g/ml.The average recovery was100.37%,RSD=1.37%(n=3).CONCLUSION:The fluconazole for injection prepared by the present technique is stable in quality and the method for content determination is accurate and practicable.

Objective To investigate the safety of different intensity anticoagulation therapy of warfarin in preventing thromboembolism in octogenarian patients with nonvalvular atrial fibrillation (NVAF). Methods The 130 patients with persistent or permanent NVAF were randomly divided into three groups: low-intensity warfarin group (35 cases, international normalized ratio, INR (1.5-2.0), moderate-intensity warfarin group (32 cases, INR 2.1-2.5) and aspirin control group (63 cases). The rate of hemorrhagic events and the effect on renal function were observed. Results The incidence of hemorrhage was the lowest in low-intensity warfarin group compared to the other groups with slight bleeding in one case. life-threatening bleeding in one case, severe bleeding in one case and slight bleeding in four cases occurred in moderate-intensity warfarin group. Life-threatening bleeding in three cases, severe bleeding in two cases and slight bleeding in six cases occurred in aspirin control group. There were significant differences in bleeding incidence among the three groups (χ2=5.13,P＜0.05). The low-intensity warfarin group and moderate-intensity warfarin group were superior to the aspirin control group in the effect on renal function (P＜0.05). Conclusions It is safe that the dose of warfarin is maintained at low anticoagulation intensity between INR 1.5 and 2.0 in octogenarians with NVAF.
