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.

Objective To investigate the application effect of drainage of intracranial hematoma in bedside skull soft channel.Methods In the hospital in October 2014 to 2015 years 5 months in the diagnosis and treatment of intracranial he-matoma in patients with selected 20 cases as the research object and the principles were randomly divided into 2 groups, and the observation group ( n=10) the application of bedside cranial awl soft channel drainage in the treatment of , control group (n=10) application of conventional drilling drainage treatment .Two groups patients therapeutic effect and complications in-cidence were compared .Results To observe the surgical treatment group the total effective rate was 90.0%, and complica-tion rate was 10.0%;Observation group , operation treatment , the total effective rate is 60.0%, and complication rate was 40.0%.Two groups of patients with surgical treatment of total efficiency and complication rates between the groups compared with statistical difference (P<0.05).Conclusion The application of bedside cone cranial soft passage drainage in intracra-nial hematoma is effective , can significantly improve the postoperative cognitive function and muscle strength , improve the a-bility to take care of themselves , and less complications .

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.

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 relationship between the methods of CPAP pressure titration (under whole night PSG or by auto-set) and CPAP compliance. METHODS Forty-five patients with serious OSAHS who had been diagnosed in our sleep lab between 2001 and 2004 and were willing to try CPAP treatment were enrolled. They were divided into A and B group according to their wills: pressure titration under whole night PSG in lab (group A) or by auto-set in their families (group B). After pressure titration, patients and their families were educated for the knowledge of CPAP treatment in OSAHS patients. Questionnaires about QOL before CPAP treatment and half year later were carried out on the phone. The decreased score was used to evaluate the effect of CPAP treatment. The hours of per day using machine were used to evaluate the compliance of CPAP. RESULTS Group A and group B got the similar decreased score (14 VS 14.3) , compliance (4.91h VS 4.97h) and adherence (85.7 % VS 88 %) . CONCLUSION OSAHS patients under go pressure titration either in lab with PSG or in their home with auto-set have the same effect and same compliance of CPAP treatment. That means the simple auto-titration can substitute the traditional titration under whole night in lab.

Starting from the experiment of Zhenjiang Rehabilitation Group in establishing a tightly-organized medical association,the authors detailed the practices and outcomes of the group in deepening the system and mechanism reforms,promoting the hierarchical medical system,and other reforms of public hospitals.Key roadblocks and causes were identified,with reform measures proposed as well.

Objective: To discuss the predictive value of liver and spleen stiffness detected by transientelasticity imaging technology on esophageal varices bleeding (EVB) of patients with hepatitis B cirrhosis. Methods: 100 patients with hepatitis B cirrhosis (18 cases were no EV, 30 cases were mild EV, 28 cases were moderate EV and 24 cases were severe EV) were selected. In these patients, 52 cases were no bleeding, 28 cases were single hemorrhage and 20 cases were multiple hemorrhage. As the Child-Pugh grading, there were 34 cases were A grade, 30 cases were B grade and 36 cases were C grade. All of the liver and spleen stiffness of these patients were detected by instantaneous elasticity imaging technology, and to compare different Child-Pugh grading of patients, different EV degree, and liver and spleen stiffness on different EVB situation. Results: The liver and spleen stiffness of patients in Child-Pugh C stage were significantly higher than that in Child-Pugh A stage and B stage, respectively (t=21.13, t=12.04, t=11.24, t=9.741; P<0.05). With the aggravating of the severe degree of EV, the liver and spleen stiffness were significant increasing, and there were significant differences between different EV degree patients for liver stiffness and spleen stiffness, respectively (F=7.494, F=8.129, P<0.05). The liver and spleen stiffness of multiple hemorrhage group were significant higher than that of no-hemorrhage group and single hemorrhage group, respectively (t=13.13, t=18.14, t=12.15, t=17.46; P<0.05). Conclusion: By using instantaneous elasticity imaging technology to detect liver and spleen stiffness can predict EVB of patient with hepatitis B cirrhosis and it has higher clinical value, therefore, it is a sophisticated noninvasive examination with simple operation and better repeatability.

The public hospital non-administration action is a strong power push to deepen the public hospital reform, also as an important goal of the institution reform, which has great significance. It introduces the goal of public hospital administrative, analyzes the key problems to be solved in the process of administration and puts forward the concrete path to the administration.
