Objective To investigate the value of ultrasound locates the appendectomy and guide appendec -tomy incision in small incision appendectomy .Methods According to the digital table ,80 patients with acute appen-dicitis diagnosed by B ultrasound examination , were randomly divided into the observation group , and the control group.Each of the group has 40 cases and use small incision appendectomy .In the observation group , mark corre-sponding appendix root in the abdominal wall surface when use B ultrasound examination ,and mark again in anesthe-sia before surgery.Design of a 2~2.5cm minimal incision according to appendix after anesthesia marker ,distance measurement before and after .The control group did not use B ultrasound localization ,minimal incision by McBurney point or near tenderness point .Between the two groups in operation time ,bleeding volume ,postoperative exhaust time , hospitalization time,complications.Results Ultrasound before and after positioning distance was (1.9 ±0.6)cm,and the preoperative immediate ultrasound localization of appendix and intraoperative exploration results ,and preoperative ultrasound localization in observation group ,the average operation time was better than no ultrasound localization of group(P<0.05).The amount of bleeding volume,postoperative exhaust time,hospitalization time,complications had no obvious difference .Conclusion Preoperative immediate ultrasound can more accurately reflect the position of ap-pendix ,favorable operation in small incision appendectomy is quickly ,shorten the operation time .

Objective To evaluate the efficacy and safety of the hyper-CVAD/MA regimen as an intensified treatment option for 28 T cell and aggressive/highly aggressive B cell NHL in Chinese patients. Methods Clinical data of 28 NHL patients treated with hyper-CVAD/MA regimen from Jan 2005 to Sep 2008 were retrospectively analyzed. Results 27 NHL patients were available for the efficacy analysis, with a response rate of 70.4 %. For the 13 B cell lymphoma cases, the response rate was 84.6 %. The main toxicity was Grade Ⅲ or Grade Ⅳ myelosuppression in all cases and 2 treatment related deaths. Conclusion Hyper-CVAD/MA regimen had a high response rate in T cell and aggressive /highly aggressive B cell NHL lymphoma, companied by significant toxicity when treating Chinese patients. Further clinical practices are needed to pick up a suitable dose which can balance efficacy and safety.

Objective To investigate the prevalence of the loss of basic activities of daily living (ADL) and instrumental ADL (IADL) influencing factors in the elderly population in China and provide evidence for the effective keeping and improvement of the elderly daily living.Methods The information about demographic characteristics and activities of daily living of elderly Chinese aged ≥ 60 years were collected by using the data of 2013 China Health and Retirement Longitudinal Study.The elderly's ADL of taking bath,eating,getting in and out of bed,dressing,toilet use,and defecating and the IADL of doing housework,cooking,making phone call,taking medicine,shopping and money managing were evaluated.The differences in loss of ADL among different populations were compared by x2 test and logistic regression analysis was conducted to identify influencing factors for the loss of ADL and IADL.Results The overall ADL loss rate was 23.8％ and the overall IADL loss rate was 35.4％ in elderly Chinese.The proportion of having trouble in toilet use was highest among all ADL items,followed by bathing and getting in and out of bed.The proportion of having trouble in making phone call was highest among all IADL items,followed by doing housework and money managing.Female,older age,low educational level,living in central and western China,chronic diseases and disability were factors associated with ADL loss and IADL loss;the divorced or separated,widowed were more likely to have ADL loss;people living in rural area were more likely to have IADL loss.Conclusion It is necessary to take comprehensive measures to delay and reduce the ADL and IADL loss in elderly Chinese and provide timely and appropriate health care for the elderly with ADL or IADL loss.
