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.

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.

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 observe the effects of cryptotanshinone (CTS) on cytochrome P450 (CYP) isoforms in the rat liver microsomes. Method The rats were randomized into six groups according to the body weight, 3 rats in each group. CTS groups were treated with CTS at the doses of 20～540 mg/kg per day for 10 days, and the negative control group was treated with 10 mL/kg hydroxylpropyl-β-cyclodextrin solution. The positive group was injected with β-NF(80 mg/kg) intraperitoneally on the 7th day, and all the animals were sacrificed by decapitation on the 10th day after last dose. The liver was got out for the preparation of liver microsomes. The activities of six kinds of CYP isoforms were detected by cocktail in-vitro incubation method. Besides, the expression level of CYP isoforms mRNA and protein in rat liver was analyzed by reverse transcription polymerase chain reaction (RT-PCR) and western-blotting assay, respectively. Results CTS significantly increased the ac-tivity of CYP1A2 in a dose-dependent manner. In CTS groups at the dosages of 20～540 mg/kg, the activity of CYP1A2 was 60 %～430 % higher, CYP1A2 protein expression level was 130 %～320 % higher, and CYP1A2 mRNA expression level was 10 %～150 % higher than that of the negative control group. CTS had no effect on other kinds of CYP isoforms. Conclu-sion CTS can induce hepatic microsome CYP1A2 expression significantly, which indicates potential drug-drug interaction might occurred when CTS is co-administrated with those drugs metabolized by CYP1A2.

Objective To evaluate the effectiveness of discharge planning and home care for patients with peritoneal dialysis (PD).Methods A total of 60 PD patients were randomly divided into the intervention group and control group,30 cases in each group.Discharge planning and home care were carried out in the intervention group, while routine nursing and telephone follow -up service after discharge were implemented in the control group.The patientsˊscores of Zung Self -Rating Anxiety Scale(SAS),Self -Rating Depression Scale(SDS),Self management ability of patients undergoing peritoneal dialysis,complication rate and readmission rate were compared between the two groups at the next day admission,discharge,lth month and 3th after discharge.Results The scores of SAS and SDS in the intervention group were significantly lower than that in the control group at 3th month after discharge,the difference was statistically significant(tSDS =5.263,tSAS =3.812,P <0.05).The Self management ability of patients undergoing peritoneal dialysis was significantly higher than that of the control group at lth and 3th month after discharge,the difference was statistically significant (t =6.845,t =7.231,P <0.05).No significant difference in the re -admission rate (16.67%,6.67%)was found between the two groups (χ2 =0.387,P >0.05).The complication rate in the intervention group was significantly lower than in the control group at 3th month after discharge(χ2 =5.124,P <0.05).Conclusion Discharge planning and home care can effectively relieve depression and anxiety in patients with peritoneal dialysis and improve the abilities of daily life.It is worth promoting and applying in clinic.

Objective To compare the body composition of diabetic and healthy subjects and to investigate the correlation between obesity and type 2 diabetes mellitus.Methods Body composition was analyzed in 80 type 2 diabetic patients (diabetes group) and 80 healthy subjects (control group) selected at random.They were measured for body fat mass,visceral fat area,sketedtal muscle mass,waist-hip ratio,the content of protein and mineral,etc.The blood glucose,blood fat,insulin resistance index (Homa-IR) and glycosylated hemoglobin(HbA1c) were also measured.Results The means of body fat mass((19.68 ± 6.78)kg),percent body fat ((29.87 ± 8.04) ％),obesity degree ((115.93 ± 15.94) ％),visceral fat area ((104.48 ± 36.19) cm2),Body mass index(BMI) ((24.85 ± 3.51) kg/m2),chest circumference ((94.06 ±7.86) cm),waist circumference ((85.18 ± 9.50) cm) and waist-hip ratio (0.90 ± 0.05) were significantly higher than the means of healthy subjects'weight control ((-4.08 ± 6.79) kg),body fat mass ((17.31 ± 5.55)kg),percent body fat ((27.38 ± 6.47)％),obesity degree((108.88 ± 13.80)％),visceral fat area ((85.44 ±44.04) cm2),BMI ((23.43 ± 3.10) kg/m2),chest circumference ((91.11 ± 7.52) cm),waist circumference ((80.79±8.17) cm) and waist-hip ratio (0.86 ± 0.05) (t=2.55,2.30,3.12,2.86,2.73,2.28,3.12 and 4.76 respectively;P ＜0.05),body mass control ((-7.01 ± 7.49) kg),obesity control ((-8.53 ± 6.66)kg),muscles control((1.52 ± 1.43) kg) were lower than control group:the body mass control((-4.08 ±6.79) kg),obesity control ((-6.39 ± 5.78) kg),muscles control ((2.31 ± 2.09) kg).The uric acid was negatively related to weight control and obesity control (r =-0.43,-0.42 ; P ＜ 0.01),and were positively related to visceral fat area,percent body fat,waist-hip ratio,BMI,obesity degree,chest circumference,waist circumference and body fat mass (r =0.32,0.31,0.40,0.36,0.36,0.31,0.42,0.42 ; P ＜ 0.05).The triglyceride was negatively related to weight control and obesity control (r =-0.44,-0.41 ;P ＜ 0.01),and were positive related to percent body fat,waist-hip ratio,BMI,obesity degree,chest circumference,waist circumference and body fat mass(r =0.27,0.35,0.46,0.46,0.35,0.42,0.42 ;P ＜ 0.05).Conclusion The body fat and fat distribution are significantly different between diabetic and healthy subjects.There may be some relationship between central obesity and diabetes.
