Objective To analyze and evaluate the use of small incision in the treatment of senile intertrochanteric fracture in artificial femur head replacement.Method 79～98 years old senile patients suffered from intertrochanteric fracture use small incision and artificial femur head replacement,a total of 18 cases including male 6 cases and female 12 cases,averaged eighty six years old,type of fracture according to Evans classification,type Ⅲ six cases,type Ⅳ eight cases,type Ⅴ four cases.Result 18 cases were followed up for 3～19 months,no case died,joint function in good situation,6～21 days post operation walk with help of tools,the average time was 7 days,use activity rate of hip joint,degree of pain and living self-service situation as criteria,success rate reached 91%,no relaxation or descendent of prosthesis.Conclusion Trauma is relatively small in use small incision and artificial femur head replacement in the treatment of senile intertrochanteric fracture,the result is satisfactory.

Objective To investigate the correlation among mammographic features、pathology and molecu-lar biology markers of breast infitrating ductal carcinoma(IDC) tissues.Methods The mammographic features of 93 cases with IDC confirmed by surgery and histopathology were analyzed retrospectively.The mastectomy specimens of the IDC were stained with immunohistochemistry,and the expression of ER、PR、C-erbB-2 were measured.The rela-tionship between the immunohistochemical pathologic results and mammographic features was analyzed.Results A-mong the 93 cases of IDC,ER positive expression was positively correlated with the spiculate margin of breast cancer (P<0.05);C-erbB-2 positive expression was positively correlated(P<0.05).Moreover,ER and PR positive expres-sion showed a significant inverse correlation with the calcifying of breast cancer(P>0.05);ER and PR positive ex-pression was positively correlated with the transfer of lymph(P<0.05);there existed correlation between the positive expression of C-erbB-2 and lymphatic metastasis and pathohistology grade(P<0.05).Conclusion There was a pos-itive correlation among IDC mammography、pathology and the abnormal value of ER、PR and C-erbB-2.The X-ray mammography could reflect the diagnosis value of ER、PR and C-erbB-2 roughly,and thadpractical value in determi-ning prognoses and endocrinotherapy.

Objective To evaluate whether flexible ambrosia,by which people can take special prebiotics instead of dining to alleviate their sense of hunger is a healthy, safe and effective weight loss method by analyzing the effects of flexible ambrosia on body weight, body composition, physiological and chemical indexes of young volunteers.Methods Young volunteers were tested on flexible ambrosia for seven days using special prebiotics instead of normal food.Body weight, waist circumference, body composition and blood biochemical indexes ( blood pressure, blood glucose, liver function, renal function, blood electrolyte, and blood lipid ) were measured and recorded before and after the test respectively.The volunteers′subjective feelings ( hunger, energy, fatigue, etc) were recorded during the test every day by way of e-form records.Results All volunteers of the flexible ambrosia test reduced their body weight, body mass index (BMI), waist circumference, visceral fat index (VAI) and body fat rate (Fat,%)significantly (P<0.01)in seven days, while the body water rate, muscle mass, body protein and bone did not significantly change or rise.There was no significant functional abnormity of the liver kidney, or blood electrolytes and blood lipid.All volunteers were in good physical condition, high-spirited and slept well, high quality sleep, without any obvious hunger and fatigue response in seven days.Conclusion Flexible ambrosia seems to be a healthy, safe and effective method, and provides an important scientific basis and reference for weight loss in the military.
