Objective To study the effect of nasal decontamination on clinical index of elderly patients with long -term indwelling nasogastric tube.Methods 89 elderly patients with long -term indwelling nasogastric tube were randomly divided into nasal decontamination group and routine treatment group.The sputum culture positive rate of bacterial and the incidence of pulmonary complications,pharyngitis,sinusitis of the two groups were observed. Results Sputum Staphylococcus aureus positive rates in the nasal decontamination group and conventional group were 13.043% (6 cases)and 39.535% (17 cases)respectively,the difference was significant(χ2 =8.139,P =0.004).The incidence rates of pulmonary infection in the nasal decontamination group and conventional group were 4.348% (2 cases)and 18.605% (8 cases)respectively,the difference was significant(χ2 =4.529,P =0.033). The incidence rates of pharyngitis in the nasal decontamination group and conventional group were 10.870%(5 cases)and 37.209% (16 cases) respectively,the difference was significant (χ2 =8.553,P =0.003 ). Conclusion Nasal decontamination can decrease the positive rate of sputum bacterial culture,the incidence of pulmonary infection and pharyngitis in elderly patients with long -term indwelling nasogastric tube.For its efficacy and safety,it deserves clinical application.

Objective To assess the value of ultrasonic elastography in the diagnosis of special type breast cancers. Methods Routine ultrasonograms, color Doppler flow images and elasticity images of 13 patients with special type breast cancer confirmed surgical pathologically were retrospectively analyzed. Results The score of mucinous carcinoma, inflammatory breast cancer (1 patient), lactation breast cancer, invasive micropapillary carcinoma, tubular carcinoma and invasive lobular carcinoma (2 patients) were 4-5. The score of 1 patient of invasive lobular carcinoma was 1 and 1 patient of lactation breast cancer was 3. The characteristics of color Doppler flow imaging of majority patients were varies, while no obvious lesion was observed in Paget's disease. Conclusion Ultrasonic elastography is helpful to the diagnosis of inflammatory breast cancer, lactation breast cancer, invasive micropapillary carcinoma of the breast, papillary carcinoma and tubular carcinoma of the breast. Early diagnosis of Paget's disease still depends on pathology.

In the latest 50 years,the radical dissection rate of colonic cancer and the 5-year survival rate have been improved as colonic surgery techniques improve.In 1991,Jacob performed the first laparoscopic hemicolorectomy in the world,and data from multiple prospective studies have shown no significant difference between laparoscopic and open radical resection of colonic cancer in aspects of postoperative survival and incidence of tumor recurrence.In the year of 2009,Hohenberger suggested the concept of complete mesocolic excision (CME).Clinical data Showed that CME could further improve the postoperative survival and reduce the incidence of tumor recurrence,and it could become the standard surgical procedure following total mesorectal excision.

ObjectiveStudy on the effect of nasal decontamination hefor aerosol inhalation in elderly patients with general anesthesia postoperation.Methods130 elderly patients with general anesthesia postoperation were randomly divided into routine treatment group and nasal decontamination group.The time of first sputum,the time of postoperative sputum changing characters,respiratoty-related indicators,sputum cuhure positive rate of bacterial,the incidence of postoperative pulmonary complications was examined.ResultsCompared with routine group,nasal decontamination group obviously shorten sputum character changing time ( P ＜ 0.05 ).Postoperative nasal decontamination group and conventional group sputum Staphylococcus aureus positive rate were 7.7％ (5 cases) and 20.0％ ( 13 cases) respectively,the difference was significant(x2 =4.13,P ＜0.05).ConclusionGiven nasal decontamination before aerosol inhalation could improve character of sputum and reduce sputum bacterial culture positive rate,and had good efficacy and safety.

Objective To explore the effective treatment in children of abdominal allergicpurpura.Methods To retrospectively analyze the clinical data of 54 children with abdominal allergicpurpura.54 cases were divided into three groups.Each 18 cases in group Ⅰ,groupⅡ,and group Ⅲ.It was used large doses of methylprednisolone in the group Ⅰ,ranitidine in the groupⅡ,and cimetidine in the groupⅢ,based on conventional treatment.To analyze the effect and adverse effect after the treatment.Results The effect of groupⅠ,and groupⅡ,was significantly higher than group Ⅲ(t=11.775,8.901,7.613,5.786,10.105,12.347,all P＜0.05).There was no significant difference between groupⅠ,and group Ⅱ(P＞0.05).The adverse effect of groupⅠ,was significantly higher than the other groups(x2=4.500,5.017,all P＜0.05).Conclusion The treatment of hormone had obvious effect in children with abdominal allergicpurpura,but it had some risks in the gastrointestinal,so we should close observe the gastrointestinal tract in children.Ranitidine and cimetidine are the drugs of inhibiting gastric acid secretion,but the ranitidine much better than cimetidine.

The discovery of limbal stem cells is the key advancement in ophthalmology in the 20th century.Many clinical researches have proved that limbal stem cells transplantation is an effective method to treat severe ocular surface diseases.However, some important issues associated with the identification,isolation,standardized culture in vitro and differentiation after transplantation are still not clear and need to be paid more attention.Strengthening the underlaying research in this field will play important role in treating corneal blindness.

Objective:To determine the curative effect of Ginkgo Biloba extract on the back chapped skin in SD rats. Methods:Totally 60 SD rats were randomly divided into 6 groups with 10 rats in each. One group was the blank control group, while the other five groups with the same back chapped skin were respectively treated with different therapy regimen, namely one group was the model group without any treatment, one group was urea group treated with the commercially available urea, and the last three groups were re-spectively treated with Ginkgo Biloba extract at the dose of 5%, 1% and 0. 2%. The pathological tissue was observed after HE stai-ning, and the content of hydroxyproline ( Hyp) in skin was determined by alkaline hydrolysis. Results:The skin lesion and the score of pathological section were studied and the content of Hyp in the damaged skin was determined. The comprehensive score for the groups was 0, 13. 2, 7. 4, 11. 0, 5. 8 and 6. 6, respectively, and the content of Hyp was (4. 57 ± 0. 07), (2. 41 ± 0. 27), (3. 29 ± 0.57), (2.55 ±0.31), (3.24 ±0.26) and (3.37 ±0.24) μg·mg-1,respectively. There was significant difference in the curative effect between the Ginkgo Biloba extract groups at high dose (5%) and medium dose (1%) and the model group (P<0. 05), which showed no obvious difference when compared with the urea group (P>0. 05). Conclusion:The extract of Ginkgo Biloba has a certain effect on the back chapped skin in SD rats, which may contribute to the external preparations of Ginkgo Biloba extract.

The goal of China's health care insurance system is to improve the fairness and accessibility of health care services for low-income people. In the past 10 years of practice, the insurance has made remarkable a-chievements and gained popularity among broad masses of people. With the support of World Bank and UK Depart-ment for International Development, China Rural Health Development Project ( hereinafter referred as Health XI Project) have used the advantages of unique funding, management and human resources to launched a series of pro-ject activities, with the main goal of achieving effective convergence between the New Rural Cooperative Medical Scheme (NRCMS) and Healthcare Financial Assistance Program (HCFAP) in order to explore the assistance system of catastrophic diseases. Some areas have achieved seamless convergence between NRCMS and HCFAP to explore the assis-tance program for catastrophic diseases in the context of confirming and optimizing the management of services covered by the project, especially conducting a series of exploration and practice activities in the aspects of increasing new funding channels to establish theCatastrophic Disease Assistance Fund, strengthening the related supporting regulations, etc. The results show that the utilization of services covered by HCFAP in the project has significantly improved, the protection level of health insurance has greatly improved, and the people satisfaction has significantly increased.
