Objective:To observe the effects of real-time and retrospective analyze of cardiac remote monitoring based on differential threshold method.Methods: Xin An Bao XAB - M3AG ECG remote monitoring system which based on the differential threshold method of improvement being used to determine the parameters of electro cardio signal was installed in 8957 patients.Results: We had collected all 46967 ECG real-time data, including 9564 manual transmission, 25830 timing transmitting and 11573 automatically transmission. 5728 of automatically transmission was with arrhythmia (49.5%) and the others of automatically transmission was attribute to inference.Conclusion: The results showed that algorithm complexity based on the improved differential threshold method is low, the precision is high and it has a good real-time performance. It realized the real-time monitoring of ECG.

Hemodynamic effects of Laigechongji (LGCJ)were studied in anesthetized open-chest dogs. LGCJ(in doseof 8. 5 and 17.0g/kg,id. )decreased significantly SBP, DBP, MAP, HR, LVSP, +dp/dt max and TPVR, 30~45 mins after medication,and continued for about 90~ 150mins. However,they had no significant effects ondp/dt max,LVEDP,CO,CI,SV and SI. These results suggest that LGCJ may cause hypotension,and its hypotensive effects may be related to its bradycardiac,negative inotropic and vascular resistance reducing activities.

The effect of Hippophae rhamnoides L. juice (HRJ) on the immunologic function and the inhibition of tumor growth in mice were reported. Kunming mice were administered orally with HRJ for 7 days. The IL-2 produced by splenocytes, the reactivity of splenocytes to IL-2 were markedly stimulated (P

Objective To report the technique and outcome of combined transplantation of bilateral vascularized fibulas to repair the segmental femoral defect Method In the period from October 1984 to May 1992, bilateral vascularized fibula transfer was done to treat femoral defects in 9 cases, in which there were 5 cases of bone tumor, 3 cases of pathological fractures following chronic osteomyelitis and 1 case of posttraumatic bone defect The length of the transferred fibulas ranged from 12 cm to 22 cm and averaged 16.25 cm Result Except 1 case in which thigh amputation was done 6 months after operation because of local recurrence of the chondrosarcoma, all the transferred fibulas united solidly with the host bones 3-6 months after operation The repaired limbs started weight-bearing at the third to seventh postoperative month Conclusion To repair a femoral defect over 10 cm in length, combined transfer of bilateral vascularized fibulas is the treatment of choice with short therapeutic process and good results.

Objective To investigate the influence of tooth preparation surface roughness and different dental ce-ments on adhesive strength, and provide some reference information on the selection of dental rotary instruments and dental cements. Methods Sixty dentin samples were prepared and randomly divided into 3 groups. Samples from group A, B and C were grinded by diamond burs with grit-sizes of 125μm, 60μm and 28μm respectively. Two samples selected randomly from each group were observed under scanning electron microscope (SEM) for the surface microprofile. The remaining 18 samples from each group were evenly divided into 3 subgroups. Each subgroup was teamed with one of 3 dental cements:zinc polycarboxylate cement (ZP), glass ionomer cement (GI) and resin-modified glass ionomer cement (RMGI). Co-Cr alloy casts were cemented onto the dentin samples, and the adhesive strength was tested. Meanwhile, the types of failure were re-corded for each sample. Results The surface roughness of tooth preparation samples showed a downward trend in group A, group B and group C. Among the involved 3 dental cements, RMGI exhibited the highest adhesive strength, and there was no significant difference in the adhesive strength between ZP and GI. Among different combination subgroups, A-RMGI had the highest adhesive strength, B-RMGI run the second place, while C-ZP and C-GI were proved the lowest. However, there was no interaction between the two factors. Furthermore, group A mainly showed failure typesⅠandⅡ, group B evenly showed all the failure types and group C mainly showed failure typesⅡandⅢ. Conclusion The adhesive strength is related to the surface roughness. RMGI exhibits the highest adhesive efficiency. There is no obvious compatibility in particular surface roughness and dental cements.

The paper proposed a new method to design and fabricate a flexible neural microelectrode arrays (MEA) for retinal prosthesis, the ion-beam technology was introduced to decrease the width of conductive wires and the distances between wires, a high density MEA (120 microelectrodes with a matrix of 10 x 12) was fabricated on a single layer of polymer from this. The MEA was proved to possess a fine electrochemical property. In vitro test, the average impedance of MEA on 1 kHz was 16 k omega +/- 2 k omega and the average phase difference was -85 degrees +/-30 degrees.

Objective To evaluate the effect of the gastric signet ring cell cancer(SIG)on the T,N,M stages. Methods Three hundred and fifty-one patients undergoing D2 or greater gastrectomy for gastric cancer were ana lyzed retrospectively.The T,N,M stages of 59 patients with SIG and 161 patients with tubular adenocarcmonla (TUB)were compared using univariate and multivariate analysis.Results The chi-square test showed that there were not significant differences in T,N,M stages between TUB and SIG.Multivariate Logistic regression analysis indicated that SIG Was not a independent factor influencing the T,N.M stage.Conclusion Gastric cancer with SIG has not higher T,N,M stages than that with TUB.

OBJECTIVE　To study the effects of Panax quinquef olium 20S-protopanaxdiol saponins extracted from the leaves of panax qu inque-folium (PQDS) on the hemodynamics and cardial oxygen metabolism in dogs with acute myocardial infarction (AMI).METHODS　The paramete rs of hemodynamics and cardial oxygen metabolism were determined by using the mo del of ligation of LAD in the anaesthetized open-chest dogs.RESULTS 　In dogs treated with PQDS (in a dosage of 10 and 20 mg*kg-1 iv infusion),the myocardial blood flow (MBF) was increased and coronary vascular re sistance (CVR) was decreased significantly.The heart rate (HR) was slowed.The ar terial blood pressure (ABP),left ventricular pressure (LVP),the maximum rise rat e of left ventricular pressure(+dp/dtmax),left ventricular work index (LVW I) and total periphery resistance(TPR) were reduced,whereas the stroke index(SI) and cardiac index (CI) were increased.In addition,the decreasing range of the m aximum decline rate of left ventricular pressure(-dp/dtmax) and the rising range of left ventricular end diastolic pressure (LVEDP) were reduced.Meanwhile the cardiac oxygen consumption,myocardial oxygen utilization rate and cardiac o xygen consumption index were also decreased.CONCLUSION　PQDS had protective effects on acute myocardial ischemia including improving heart fu nction,decreasing cardiac oxygen consumption and increasing myocardial blood flo w,etc.
