1.Medical image processing based on wavelet characteristics and edge blur detection.
Journal of Biomedical Engineering 2014;31(3):493-498
To solve the problems of noise interference and edge signal weakness for the existing medical image, we used two-dimensional wavelet transform to process medical images. Combined the directivity of the image edges and the correlation of the wavelet coefficients, we proposed a medical image processing algorithm based on wavelet characteristics and edge blur detection. This algorithm improved noise reduction capabilities and the edge effect due to wavelet transformation and edge blur detection. The experimental results showed that directional correlation improved edge based on wavelet transform fuzzy algorithm could effectively reduce the noise signal in the medical image and save the image edge signal. It has the advantage of the high-definition and de-noising ability.

3.Role of immunoglobulin in treating chronic obstructive pulmonary disease with fungal infection
Chinese Journal of Infection Control 2014;(5):281-283
Objective To explore the clinical effect of intravenous immunoglobulin(IVIG)on chronic obstructive pulmonary disease(COPD)and fungal infection.Methods Seventy-two COPD patients with fungal infection were randomly and equally divided into conventional and intervention group.Patients in conventional group were treated with common schedule for COPD plus antifungal agents;patients in intervention group received 1 0 g/d IVIG besides routine therapy.Length of hospital stay and prognosis were recorded,and therapeutic effectiveness were evaluated. Results The effectiveness rate of intervention group was significantly higher than that of conventional group ([88.89%,32/36]vs [66.67%,24/36]);the average length of hospital stay was significantly shorter than conven-tional group ([12.62±7.51]d vs [20.81±6.92]d),and mortality was lower than conventional group ([5.56%, 2/36]vs [22.22%,8/36]),the differences were statistically significant (P<0.05).Conclusion IVIG for treating COPD with invasive pulmonary fungal infection can improve therapeutic efficacy,shorten length of hospital stay and decrease mortality rate.
4.Potential drugs for early Alzheimer's disease:Donanemab injection
The Chinese Journal of Clinical Pharmacology 2024;40(9):1372-1374
Donanemab is a novel anti-amyloid antibody medication that is primarily used to treat early-stage symptomatic Alzheimer's disease.Clinical investigations have demonstrated that it modulates issues with cognitive function and everyday functioning.Preclinical research has discovered that it reduces amyloid deposition in the hippocampus and cortical layers of the brain.To better comprehend cutting-edge novel medications,this article examines the latest research on donanemab.

Objective To study the location of coronary chronic total occlusion and the correlatin between coronary chronic total occlusion and coronary collateral. Methods SPSS was used to analyze the general clinical and coronary angiographic data of 113 patients with coronary bypass surgery performed. Results There were 61 patients with coronary chronic total occlusion. 71 sites of coronary chronic total occlusions were observed by coronary angiography, of which, one was located in left main coronary artery (0 9%), 17 in proximal left anterior descending artery (15 0%) , 9 in middle left anterior descending artery (8 0%), 3 in distal left anterior descending artery (2 7%), 5 in proximal left circumflex artery (4 4%), 6 in middle left circumflex artery (5 3%), 3 in distal left circumflex artery (2 7%), 9 in proximal right coronary artery (8 0% ), 10 in middle right coronary artery (8 8% ) and 8 in distal right coronary artery (7 1% ). There were 72 patients with coronary collateral. The coefficient of correlation between collateral and coronary chronic total occlusion was 0 707 (P=0 000 ).Conclusions Coronary chronic total occlusion is frequently located in proximal, middle left anterior descending artery and right coronary artery. There is significantly positive correlation between collateral and coronary chronic total occlusion.

Objective To study the treatment of renal artery stenting for patients with coronary artery heart disease and renal artery stenosis who need coronary atery bypass graft (CABG) and its effect on preventing acute renal dysfunction after CABG. Methods From April 2001 to January 2005, renal artery stenting was carried out in 82 patients (a total of 104 renal arteries) with CHD and renal artery stenosis who needed CABG. Among the 82 patients, 77 of them accompanied with hypertension and 21 of them had abnormal renal function. Heparin was selected as anticoagulant other than anti-platelet drug and low molecular weight heparin before stenting. Results All of the stents were successfully implanted in 104 renal lesions without complication. Blood creatinine (Cr) reduced in 9 patients with renal dysfunction by the time of discharge. Three patients had blood Cr increased provisionally after stenting. Four patients with normal pre-operational renal function showed transient increase in blood Cr after stenting. All of the patients with transient blood Cr elevation had bilateral renal artery stenosis. Conclusion Renal artery stenosis may cause acute renal failure after CABG. Pre-CABG renal artery stenting may prevent the occurance of acute renal failure after operation.
