Objective To investigate the relativity for weight of macrosomia predicted by ultrasound and clinical measurements . Methods 1 037 subjects who were delivered in May to November 2012 ,in Chongqing Health Center for Women and Children ,were collected and analyzed satistically .The parameters for the comparisons included maternal abdominal circumference (MAC) ,fundal height(FH) ,and fetal diameters measured by ultrasonic imaging such as biparietal diameter (BPD) ,head circumference(HC) ,femur length(FL) ,and abdominal circumference(AC) .The coincidence was calculated with real weights and compared with clinical predic-tions .Results When FH+ MAC 134 cm ,the accuracy of preliminary screening for macrosomia is the highest ,the area under the ROC curve is 0 .895 .Combining with the abdominal circumference(AC) by prenatal ultrasound ,the highest prediction rate of mac-rosomia is 75 .2% .when Fetal AC≥37 cm ,macrosomia incidence rate took 91 .7% .Conclusion Pregnant women with FH+MAC<134 cm ,whose incidence of Macrosomia is low .While if the FH+MAC≥134 cm ,combining with the prenatal ultrasound whose fetal AC>36 cm ,especially ≥37 cm ,the possibility of macrosomia is very high .

Objective To study the rationality in the use of proton pump inhibitors (PPI) to stress ulcer(SU) prophylaxis in pa-tients receiving aseptic-contaminative and contaminative incision operation .Methods A retrospective analysis was performed on the use of PPI to SU ,which taken from surgical patients received aseptic-contaminative and contaminative incision operation and hospi-talized from January 2013 to April 2013 .Results Among 1 745 patients in the study ,540(30 .95% ) received a stress ulcer prophy-laxis with PPI .The rate of prophylaxis to ICU ,general surgery ,urology ,thoracic surgery and neurosurgery was higher than other departments(except for between ICU ,thoracic surgery ,neurosurgery and orthopedic) .A total of 232 patients had risk factors , 72 .41% of the patients who received prophylaxis .A total of 1 513 patients did not have risk factors ,24 .59% of the patients who received prophylaxis ,the rate of prophylaxis to general surgery ,thoracic surgery and urology was higher than other departments (except for ICU ,and between thoracic surgery with orthopedics ) .In prevention of SU ,the usage rate of Lansoprazole was higher than that of Omeprazole and Pantoprazole .Preoperative prophylactic usage rate was 14 .44% .Excessive dosage was 0 .93% .Preven-tive medicine treatment longer accounted for 12 .78% .Conclusion The phenomenon such as non-risk factors ,inappropriate of medi-cation time and long course of treatment are existed ,when physicians use the PPI for SU prophylaxis in surgical patients receiving aseptic-contaminative and contaminative incision operation .Therefore ,treatment recommendations for SU prophylaxis are needed to restrict PPI use for justified indications .

Objective To investigate the changes of serum N-terminal proBNP (NT-proBNP) ,carbohydrate antigen 125(CA-125) and high sensitive CRP(Hs-CRP) levels in patients with chronic heart failure(CHF) ,to evaluate the severity of CHF using the three markers alone or in combination .Methods A total of 62 patients with CHF(CHF group) from our hospital were select-ed .Among them ,13 cases were in NYHA class Ⅱ ,27 cases were in class Ⅲ and 22 cases were in class Ⅳ .The control group in-cluded 54 patients without CHF .Serum levels of NT-proBNP ,CA-125 and Hs-CRP were detected in CHF group and control group . The left ventricular ejection fraction(LVEF) were detected by echocardiography .Results The serum levels of NT-proBNP ,CA-125 and Hs-CRP of CHF group before treatment were significantly higher than those of control group (P<0 .01) ,and the serum levels increased with the degree of severity of heart failure .There were statistically significant difference among patients in NYHA classⅡ ,class Ⅲ and class Ⅳ (P< 0 .01) .There was a high correlation between NT-proBNP ,CA-125 and LVEF (NT-proBNP vs . LVEF ,r=0 .934 ,P<0 .01 ;CA-125 vs .LVEF ,r=0 .878 ,P<0 .01) ,a low correlation between Hs-CRP and LVEF(r=0 .437 ,P<0 .05) .Compared with the single marker detection ,the combined detection of NT-proBNP ,CA-125 and Hs-CRP increased the AUC .Conclusion The combined detection of NT-proBNP ,CA-125 and Hs-CRP can increase the value of the observed severity of heart failure .
