This paper introduces a practical and real -time R wave detection algorithm as well as its realization and adjustment by DSP/BIOS of RTOS. With DSP/BIOS of RTOS applied, the adjustment and evaluation of real-time program for ECG are facilitated and the program stability is enhanced.

AIM: To explore the anatomical changes of the optic nerve head in cats after radial optic neurotomy (RON).METHODS: The normal anatomic data were obtained from 12 healthy cats. A total of 18 healthy cats were used in the experiment, which were divided into four groups: each operative group was executed at the :Lst, 15th, 30th, 90th day after undergoing RON unilaterally.(six in 1st group). The enucleated eyes of each operative group were cut section routinely and embedded in paraffin, the cross sections were stained by special staining.RESULTS: At the 1st day after operation, the incision came into being and connected with cerebral subarachnoid space of orbital optic nerve. At 15th day, incision was fusiform and hyperplastic neuroglial cells and fibroblasts aggregated at the incision. At 30th day, there was obvious proliferation of type fibril at the neurotomy. The aligned texture of collagen fibril of the lamina cribrosa near the incision was moved close to each other. At the 90th day, a discrete scar was noted at the site which reached the cribriform and sclera.CONCLUSION: RON can cut scleral ring and piamater of optic nerve sharply. The incision of RON connects with subarachnoid space of orbital optic nerve and becomes broaden gradually at the site of scleral ring. The potential role of incision of RON is relevant to the subject.

Using the experiences of domestic and other countries on rehabilitation nursing of patients with femoroacetabalar impingement for reference,a balanced rehabilitation procedure was designed and implemented on 16 patients underwent arthroscopic bone forming surgery in acetabulum and femoral head and neck junction.The patients could master the correct metheds of functional exercises.As a result,no postoperative complications occurred.The score of modified Harris hip rating was increased from 62.4 points before surgery to 92.5 points at six months after surgery.

Objective To understand the significance of upper eyelid swelling in early diagnosis and treat-ment of infectious mononucleosis(IM).Methods We early diagnosed these patients IMwith upper eyelid swelling, fever and lymph node enlargement under five days course of disease,and compared the coincidence rate with last diag-nosis,investigated the rate of upper eyelid swelling in non -early diagnosis cases with the course of disease above one week,and evaluated the effect of ganciclovir in treating IMin two groups.Results The coincidence rate was 97.14%in early and last diagnosis groups,and the rate of upper eyelid swelling was 60.2% in non -early diagnosis group. There were significant differences in disappear of upper eyelid swelling,fever and lymph node enlargement in the two groups.Conclusion Upper eyelid swelling has important significance in early diagnosis and treatment of IM.

Objective To establish the feasibility and clinical applications of intravenous myocardial perfusion imaging with Levovist in assessing the coronary microcirculaton reserve.Methods Intravenous myocardial contrast echocardiography (IMCE) was performed pre and post dipyridamole injection in 10 cases with normal coronary angiography (group I) and 8 cases with 50% to 70% stenosis in the lift anterior descending branch(LAD) (group Ⅱ) respectively.A set of special instrumental setting and an integrated imaging approach including power Doppler imaging,incremental triggering imaging and harmonic imaging were utilized to record the apical four chamber view.The power Doppler signals of the septum were analyzed and the time amplitude curves were plotted during Levovist infusion and incremental triggering.The maximal amplitude score (A),the mean ascending slope of the curve(?) and the product of A?? were measured.The reserve of A,? and A?? were also calculated.Results At baseline,both group I and group Ⅱ had normal myocardial perfusion.After dipyridamole infusion,contrast score A increased slightly in group I and decreased in group Ⅱ without statistical significance.Both ? and A?? were increased significantly after dipyradamole (P

Objective To study the clinical application of intravenous myocardial contrast echocardiography(IMCE) in assessing myocardial reperfusion by using intravenously infused Levovist before and after percutaneous coronary interventions(PCI). Methods IMCE was performed in 20 patients with coronary artery disease(CAD) before and after PCI. The power Doppler signals of the myocardial segments were analyzed and the time-amplitude curves were plotted during Levovist infusion and incremental triggering. The maximal amplitude score(A), mean ascending slope of the curve(?) and product of A?? were measured. All the patients were followed up 3 months later for assessing IMCE items of left ventricular function. Results A significant increase was showed in A,? and A?? after PCI(P

We present the binding ability of a new peptide (CMPQVMPMC-) with dental enamel after being evaluated in the present study. Under a standard procedure, the recovery of M13 filamentous phage was greatly enhanced by displaying the peptide in phage coat protein p III. Then the cyclic peptide was synthesized using a solid method. The effect of the cyclic peptide in vitro biomineralization was tested in a single-diffusion microtiter plate gel system. Absorbance at 405 nm of each sample was recorded for 24 h at every 6 h intervals. The relatively increased values of each sample were expressed as percentages relative to the blank group (100%). The cyclic peptide resulted in a concentration-dependent delayed nucleation. In addition, the overall values of peptide groups at the end of 24 h were lower than those in the control group but much higher than those in the BSA control group.

Objective To explore the clinical manifestation and laboratory examination of chronic diarrhea in children with acquired immunodeficiency syndrome(AIDS) and analyze the reasons that causes the chronic diarrhea in children.Methods Clinical data of 7 patients (male 4 cases,famale 3 cases)with AIDS with manifestation of chronic diarrhea among the 17 cases were diagnosed as AIDS in Beijing children′s hospital from Jan.1999 to Dec.2006.The time of diarrhea,degree of dinrrhea,characteristic of stool,accompaniment symptom,laboratory examination were retrospectively analyzed.Results The average onset age was 6 years old(from 2-9 years old).The average time of diarrhea was 6 months(from 1-16 months).Four cases main complained with chronic diarrhea,3 cases came to the hospital because of fever,cough and wasting;6 cases with diarrhea,7 cases with malnutrition and anemia,5 cases accompanied hypokalemia and metabolic acidosis,6 cases had delay in growth and development,2 cases with abnormal stool routine exam,1 case with positive stool culture of fungi.All patients were with lower CD4,5 cases with lower CD4/CD8.Conclusions Chronic diarrhea is a common symptom in children with AIDS,and usually accompanied by obvious delay in growth and development,malnutrition and anemia,the reasons that causes the chronic diarrhea are consi-dered to be related with both the opportunistic infection and HIV infection.
