The pathogenesis of cancer-related sarcopenia is complicated,involving all aspects of tumor and the body's metabolism,mainly related to accelerated proteolysis and insufficient protein synthesis.Cancerrelated sarcopenia can predict antineoplastic-induced dose-limiting toxicities,increase complications,and reduce survival rate.The interventions of cancer-related sarcopenia includes nutrition,exercise,hormone therapy and other interventions.A single treatment can not reverse clinical outcome.Various interventions are still in the investigation stage,in which more evidence-based studies are needed.

Objective To explore the correlation between the levels of nitrite/nitrate(NO2/NO3) in exhaled breath condensate (EBC) and pulmonary infection in mechanically ventilated patients.Methods The clinical data from ventilated patients in critical care units of Peking University People' s Hospital from November 2006 to August 2007 were collected and analyzed.The patients' clinical pulmonary index score (CPIS) were calculated.EBC of those patients were collected via endotracheal tube or tracheostomy cannula, and the concentrations of NO2/NO3 were assayed.The level of NO2/NO3 in different CPIS patients in 24 hours' ventilation,weaning proportion in 3 days and mortality in different NO2/NO3 level patients were compared.The correlation of the CPIS and level of NO2/NO3 were explored between survival and non-survival patients.Results A total of 76 patients were enroled.The NO2/NO3 levels in patients of CPIS≤3 ,CPIS 3-6 and CPIS >6 in 24 hours of ventilation were (23.31±5.79), (28.72±9.10) and (35.42±12.10) μmoL/L respectively, with significantly differences between each other (P < 0.01).The lower the patients' concentration of NO2/NO3 was, the earlier the weaning and the lower the mortality were.The NO2/NO3 levels on 4th and 7th day were detected in 24 survival patients and 23 non-survival patients.The difference of NO2/ NO3 levels between the survival patients and non-survival patients became significant on 7th day [(29.32±9.52) μmol/L vs.(37.22±12.03) μmol/L, P < 0.01].Linear correlation analysis showed that the NO2/ NO3 level was positively correlated with CPIS (r = 0.76, P < 0.01).Condusions The NO2/NO3 level of EBC in ventilated patients is positively correlated to the severity of pulmonary infection, thus may be used as a new predictor for weaning and prognosis.

Objective To observe the efficacy of invasive ventilation (Ⅳ) in treatment of acute pulmonary edema (APE), and to explore the factors associated with prognosis. Method From March 2005 to December 2007, 23 APE patients, who were hospitalized in the EICU of People' s Hospital of Peking University and the con-ventional treatment and noninvasive ventilation were not effective, were treated by Ⅳ (PEEP 5～18 cmH2O). Blood pressure, heart rate, respiratory rate, and arterial blood gas values were recorded accurately before and after ventilation and compared with each other. Regression analysis was used to analyze the factors associated with prog-nosis. Resets Three hours after Ⅳ, the blood pressure, heart rate, respiratory rate, arterial blood gas were sig-nificanfly improved (P <0.01). Among the 23 patients, 11 survived, and the other 12 patients died. Nine pa-tients died of MOF. Among 16 patients with cardiac function Ⅲ-Ⅳ, 10 died. Among 15 patients with acute my-ocardial infarction, 9 died. Among 11 patients with renal insufficiency, 9 died. The multivariate logistic regression analysis showed that the reduced left ventricular ejection fraction, the lower mean arterial pressure, and the in-creased creatinine were the independent predictor of prognosis. Conclusions Invasive ventilation is an effective method of treating patients with acute pulmonary edema. Proper ventilation may improve the cardiac function and clinical symptoms, but it's not the fundamental measure for increasing cure rate. 1he renal insufficiency and heart failure are the independent predictor of prognosis.

Objective To explore the clinical value of high-frequency color Doppler ultrasound in the diagnosis of isolated calf muscle vein thrombosis (ICMVT). Methods Sonographic features of 175 patients with isolated calf muscular venous thrombosis were analyzed retrospectively and outcome of anticoagulant therapy in 1, 3, and 6 months was followed up. Diagnosis was established with high-frequency color Doppler ultrasound examination. Results One hundred and seventy-ifve patients presenting with 190 calf muscle vein thrombosis were included. One hundred and iffty-eight cases with 173 calf muscle vein thrombosis were diagnosed by high-frequency color Doppler ultrasound, 7 cases of misdiagnosis, missed diagnosis in 10 cases. The accuracy rate was 91.1%(173/190). Seven cases were misdiagnosed with 1 euroifbromatosis, 1 mixed hemangioma, 5 gastrocnemius hematoma. After diagnosis of ICMVT, all patients prescribed thrombolysis and anticoagulation therapy. High-frequency color Doppler ultrasound for 1, 3, 6 months after treatments revealed partial or complete recanalization without calf deep vein thrombosis. Typical sonographic features included:calf muscle venous lumen dilation, tortuous anechoic lumen or hypoechoic iflling, with tubular or branched shape in the longitudinal view and oval or round shape in the transversal view. Conclusion High-frequency color Doppler ultrasound is an accurate and reliable method in the diagnosis of the isolated calf muscular venous thrombosis.

Objective To explore the prognostic risk factors of low level malignant obstructive jaundice treated with transhapetic biliary drainage.Methods The clinical data of 142 patients with low level malignant obstructive jaundice received percutaneous transhapetic biliary drainage management from January 2010 to June 2013 were retrospectively analyzed.The study parameters included gender,age,tumor type,preoperative obstructive time,preoperative infection,drainage method,Child-Pugh grade,serum total bilirubin (TBIL),albumin (ALB),serum creatinine (SCr),the postoperative declining degree of bilirubin and postoperative antineoplastic therapy.The prognostic risk factors were evaluated.Results Single variable analysis showed that preoperative infection (P =0.006),Child-Pugh grade (P =0.004),SCr (P =0.043),the postoperative declining degree of TBIL (P =0.001) and postoperative antineoplastic therapy (P =0.015) were the related factors for survival time.The further Logistic regression analysis showed that preoperative infection (OR =3.729,95％ CI 1.332-6.363,P =0.040),Child-Pugh grade ≥ 10 scores (OR =0.513,95％ CI 0.375-1.276,P =0.018) and postoperative antineoplastic therapy (OR =0.668,95％ CI 0.210-2.026,P =0.038) were the related factors for survival time.Conclusion In treating of low level malignant obstructive jaundice with transhapetic biliary drainage,the preoperative infection,Child-Pugh grade and postoperative antineoplastic therapy may be the important related factors that affect the patient's survival time,to evaluate the prognosis of these patients has important reference meaning.

Objectives To analyze the deployment of medical equipment and its impacts on medical services of hospitals.Methods Existing data collection,a survey of public hospitals and a chart review of acute myocardial infarction(AMI)inpatients were used to collect related data.Gini coefficients,Chi-square and multivariate model were used to analyze deployment of medical equipment and its impacts on medical services.Results The number of CTs and that of CTs per million population in Pudong new area were higher than those of MRIs and DSAs,and the distribution of CTs among districts in Shanghai was relatively equal(Gini coefficient was 0.20).But lack of DSAs in some public general hospitals had affected the AMI inpatient care.Conclusions Public hospitals and governments in China should keep at a balance the demand of medical services,deployment level of medical equipment,and financial affordability for the society,governments and hospitals.

A discussion of the connotation and key issues of the new normal in the healthcare sector,with an introduction to the new normal.The furthering reform is unveiling roadblocks in the healthcare system.For example,human resources available can hardly support development of the sector, and revenue growth of tertiary hospitals in the cities will decline,while county hospitals will be further challenged by debt crisis.In the meantime of steady elevation of medical capabilities in both urban and rural areas,the gap between the two will be maintained for a while.The authors predict that the sector will be faced with restructuring essential medicine system,grading diagnosis and treatment practice,rising risks for health insurance,and growing market shares of commercial health insurance and private capital, as well as fiercer competitions to challenge public hospitals.
