Objective To investigate the clinical significance of direct antiglobulin test(DAT) in patients with chronic hepatitis B.Methods Column agglutination technique(CAT) and conventional tube technique(CTT) were used to detect red blood cell(RBC) antibodies in a total of 162 samples,including 50 cases of asymptomatic carriers,42 cases of active phases of chronic hepatitis B(CHB) patients,52 cases of severe hepatitis and 18 healthy individuals.Results The RBC count and hemoglobin(Hb) in patients with severe hepatitis were significantly lower than those in asymptomatic carriers,CHB patients and healthy individuals(P

[Objective]To investigate the influence of the two different methods on the runtime of capsule endoscope in the small bowel.[Method]There were 31 patients who accepted the examination of capsule endoscope.Among these patients,we used pro- kinetic agents or gastroscope for 12 cases with capsule endoscope staying in the stomach for more than 60 minutes.We analyzed the influence on runtime of capsule endoscope in the small bowel with the two methods above and that of the 19 untreated cases. [Result]In the control group,15 cases completed the examination on the whole small bowel,with the average runtime 234.4?70.3min,and 4 of them failed.In medicine group,5 cases completed the examination with the average runtime 121.8?103.7min. 7 cases with the help of gastroscope all completed the examination on small bowel and its average runtime was 275.3?81.8min. [Conclusion]Taking prokinetic agents tends to have more influence on the runtime of capsule endoscope in the small bowel,but it has disadvantages over the observation of small bowel diseases;Help of gastroscope takes less effect on the runtime of capsule en- doscope in the small bowel,while it loses the advantage of no traumas and sufferings.

Objective To explore the prevalence of anemia,iron deficiency and iron deficient anemia (IDA),and to identify their risk factors in 3 to 6 months infants in Dongcheng District of Beijing.Methods All the 845 infants aged 3 to 6 months who received bacille calmette guerin (BCG) vaccine during December 2010 and October 2011 in Hepingli Hospital of Beijing were invited to complete the investigation.Data (months,gender,birth weight,birth height,etc) were collected through a questionnaire survey.Infants were tested for hemoglobin (Hb),mean corpuscular volume (MCV),mean corpuscular hemoglobin (MCH),mean corpuscular hemoglobin concentration (MCHC),serum ferritin (SF) and zinc protoporphyrin (ZPP) and mothers underwent measurement for Hb,SF and serum iron (SI).Descriptive epidemiology and non-conditional logistic regression model were used to analyze the prevalence of nutritional anemia.Results The prevalence of anemia,iron deficiency and IDA was 12.06％,7.38％ and 2.11％,respectively.Non-conditional logistic regression analysis showed that the associated factor of anemia in infants was month age (vs.3-4 months age group,4-5 months age group:odds ratio (OR) =0.496,95％ confidence interval (CI) 0.272-0.905 ; 5-6 months age group:OR =0.494,95％ CI 0.234-1.043).The factors associated with iron deficiency were month age (vs.3-4 months age group,4-5 months age group:OR =0.539,95％ CI 0.266-1.088 ; 5-6 months age group:OR =0.334,95％ CI 0.125-0.891) and time of first breast-feeding (vs.the first day,the second day:OR =2.359,95％ CI 1.191-4.675; the third day:OR =1.154,95％ CI 0.450-2.963).Conclusions Our data show that iron nutrition in 3 to 6 months-old infants in Dongcheng District of Beijing was in good situation.The influencing factors of iron nutrition in infants may be month age and the time of first breast feeding.

Objective To determine the effect of different surgical modalities on hemodynamics,systemic major organ injury and survival rate following superior mesenteric artery (SMA) injury in an attempt to search a modality that conforms to principles of damage control surgery (DCS).Methods SMA was exposed in 30 domestic hybrid pigs,leaving the blood flow blocked using non-invasive vessel forceps.The animals were divided into control group,primary anastomosis group (anastomosis group) and temporary intravascular shunt (TIVS) group according to random number table.TIVS group was further divided into three subgroups:shunting for 6 hours group (TIVS-6 h group),9 hours group (TIVS-9 h group) and 12 hours group (TIVS-12 h group).At each time point,the angiography was performed for evaluation of shunt patency; hemodynamic parameters were detected,terminal ileum and SMA samples were harvested for pathological analysis.Results All groups suffered extreme physiological conditions including hypothermia,severe acidosis,hypotension,low cardiac output and low oxygen supply.Less requirement of resuscitation fluid,faster restoration of SMA blood flow,earlier clearance of lactate,milder intestinal ischemia-reperfusion injury and higher survival rate were observed in TIVS-6 h and TIVS-9 h groups,compared with anastomosis group.Patency rate in TIVS-6 h,9 h and 12 h groups was 100％,50％ and 0％ respectively.Pathologic outcome of intestine revealed diffuse intestinal necrosis in TIVS-12 h group and reversible intestinal ischemia-reperfusion injury in TIVS-6 h and 9 h groups.Conclusion For SMA injury in severe hemodynamic disarrangement and jeopardized condition,TIVS shortens intestinal ischemia time,maintains systemic hemodynamic stability,relieves intestinal injury,improves early survival rate and keeps long-term intestine patency when compared with primary vascular anastomosis.
