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 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.

Purpose: At present ,the local control of esophageal carcinoma have been improved by using intra-cavitary irradiation, but the complications a much more than before. It is necessary to study the real condition of these complications.Materials and Methods: From August 1993 to May 1994,38 patients with esophageal carcinoma were treated with external beam combined with intra-cavitary radiotherapy in our hospital. Conventional radiotherapy was used 200cGy/F,5F/W.When the dose of external beam reached 3800cGy/19F,intra-cavitary radiotherapy was added with the dose of 500cGy/F/W(patient did not receive the external beam at the same day). The total dose of external and intra-cavitary radiotherapy were 5000cGy/25F/5W and 1500cGy/3F/3W at end of the course respectively.Results: ① 68.4%(26/38) patients had esophagitis.②25 patients suffered from the non-carcinoma esophagostenosis, which was related to the length of tumor before treatment, the shade of soft tissue around lesion, the esophagitis, the diameter of esophagus cavitary and stiff of esophagus wall before intracavitary radiotherapy.③10 of 38 cases had non-carcimoma ulcer. All patients had received 1500cGy/3F/3W intracavitary radiotherapy and occured serious esophagitis, 7 of 10 suffered from the non-carcinoma stricture and ulcer before or later.④ 6 of 38 cases had the fistula and 5 patients had been exposed 1500cGy/3F/3W intracavitary radiotherapy.Conclusion: Esophageal carcinoma treated by afterloading techniques may improve the serious obstruction immediately, but it is not sure the long-term survial yet. We also find the increasing serious complications and the decreasing life quality by using this treatment.We suggests that this method only can be used as an auxilliary way with the external beam radiotherapy.

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.

Objective To evaluate the importance of clinical screening and follow up by direct colonoscopy for colorectal cancer at an early and curable stage. Methods There were 2 196 elderly people aged between 60 to 89 years. The clinical screening by direct colonoscopy was performed according to the protocol. 1 740 of 2 196(79.2%) patients were followed up every year. Results Fifty two elderly persons were found to be colorectal cancer patients by colonoscopy, with the detectable rate being 2.4%. Nineteen were diagnosed early stage colorectal cancer, accounting for 36.5% of the detected colorectal cancer. Nine among the followed up cases were detected early colorectal cancer, accounting for 45 0% of the detected colorectal cancer. The resectable rate and the 5 year survival rate was 97 7% and 80 9% for colorectal cancer, respectively. 98 9% of the cecum intubation cases was successful. The incidence of complication for colonoscopy was 0 05%. Conclusions By clincal colonscopy screening and follow up study for colorectal cancer and precancerous changes in the elderly, the patients with adenomatoid polyps were early diagnosed and treated, so it raised the detectable rate of early colorectal cancer and the level of grade prevention of colorectal cancer.
