Ultrasound diffraction tomography (UDT) possesses the characteristics of high resolution, sensitive to dense tissue, and has high application value in clinics. To suppress the artifact and improve the quality of reconstructed image, classical interpolation method needs to be improved by increasing the number of projections and channels, which will increase the scanning time and the complexity of the imaging system. In this study, we tried to accurately reconstruct the object from limited projection based on compressed sensing. Firstly, we illuminated the object from random angles with limited number of projections. Then we obtained spatial frequency samples through Fourier diffraction theory. Secondly, we formulated the inverse problem of UDT by exploring the sparsity of the object. Thirdly, we solved the inverse problem by conjugate gradient method to reconstruct the object. We accurately reconstructed the object using the proposed method. Not only can the proposed method save scanning time to reduce the distortion by respiratory movement, but also can reduce cost and complexity of the system. Compared to the interpolation method, our method can reduce the reconstruction error and improve the structural similarity.

35 % and the intraoperative blood loss was expected to be 800-1 600 ml. The operations were performed under combined general-epidural anesthesia. General anesthesia was induced with fentanyl 2-4 ?g?kg-1 , thiopentone 5 mg?kg-1 and succinylcholine 1.5mg? kg-1 and maintained with isoflurane inhalation and intermittent iv boluses of vecuronium. Epidural anesthesia was performed at T5-6 (thoracic surgery), T10-11 (upper abdominal surgery) or L3-4 (lower abdominal surgery) . A mixture of 0.1% lidocaine +0.2% dicaine was used for epidural block during operation. The patients were randomly divided into 2 groups: (1) ANIH group ( n = 18) and (2) AHH group ( n = 20) . Blood volume (BV) was calculated according to following formula: BV (ml) (male) = Height (cm)? 28.5 + Body weight (kg) ? 31.6 - 2 820,BV(ml) (female) = Height(cm)? 16.25 + Body weight (kg) ? 38.46 - 1 369. 1 000-1 200 ml of 6% HES (200/0.5) and 500 ml of lactated Ringer's solution (about 25%-30% of BV) were infused at a rate of 50ml?min-1 when induction of anesthesia was started in both groups. In group I (ANIH) 400-600 ml of blood (about 10%-15% of BV) was removed through radial artery before induction of anesthesia. The removed blood was reinfused at the end of surgery. Vital signs (BP,HR,CVP and ST-T changes) , Hct, oncotic pressure and arterial blood lactate concentration were monitored during operation. Results The vital signs were fairly stable during perioperative period in both groups. Transient hypotension developed in 16.7% (3/8 in group Ⅰ ) and 15.0% (3/20 in group Ⅱ ) of patients during induction of anesthesia. CVP was significantly elevated in both groups but the increase in CVP was significantly higher in group Ⅱthan that in group Ⅰ . In group Ⅰ (AN1H) moderate hemodilution was achieved (Hct = 29.9% 2.9%) while in group Ⅱ (AHH) only mild hemodilution was achieved (Hct = 32.9% ?2.9%) .Hct was significantly higher in group Ⅰ(31.5% ?5.1%) than that in group Ⅱ (27.7% ?3.6%) at the end of surgery. Blood loss was comparable between the two groups, and oncotic pressure and blood lactate level were within normal range in both groups. Conclusion ANIH is more effective and safer than AHH without obvious adverse effects, and can avoid exceedingly high CVP commonly seen in AHH. ANIH is a hemodilution technique of choice in the elderly patients.

Objective To learn the effect of individualized nutritional support in the treatment of severe acute pancreatitis and provide an effective nutritional support therapy for the disease.Methods 97 patients of severe acute pancreatitis were randomly divided into 51 cases of observation group and 46 cases of control group.The control group was given standard parenteral nutrition.The observation group was given the same heat and support stage of individual nutrition nitrogen.Hemoglobin (Hb),albumin (ALB),pre albumin (PA)and transferrin (TFN)of the two groups were detected before and after treatment.The recovery time of serum amylase,resumed oral intake time, hospitalization time and hospitalization expenses of the two groups were observed.The occurrence of gastrointestinal complications was observed in the two groups during the treatment period.Results Compared with before treatment, after treatment Hb,ALB,PA,TFN of the two groups were significantly increased (t =4.114,7.540,5.556,8.307 and 1.994,3.970,2.906,5.099,all P <0.05).After treatment,ALB,PA,TFN of the observation group were higher than the control group (t =2.249,2.256,3.630,all P <0.05).After treatment,recovery time of serum amylase,resumed oral intake time,hospitalization time and hospitalization expenses of the observation group were lower than the control group (t =3.191,5.245,4.846,8.762,all P <0.05).The incidence rate of gastrointestinal complications of the observation group was 11.8%(6 /51),and that of the control group was 15.2%(7 /46),the difference was not statis-tically significant (χ2 =0.248,P >0.05).Conclusion In the treatment of severe acute pancreatitis,individualized nutritional support has better curative effect,low incidence of complications,with good clinical application value.

Objective To demonstrate in vivo that there is different degree myocardium apoptosis during acute ischemia and reperfusion and to explore prelimarily the relations between myocardium apoptosis and the expression of Bcl 2/Bax protein in rats. Methods The morphologic features of apoptotic cardiocytes were pursuited by transmission electron microscopy.DNA extracted from cardiocytes were used to identify the apoptotic DNA ladder by agarose gel eletrophoresis. DNA fragmentation was identified histochemically by TUNEL staining. Expression of Bcl 2/Bax protein in apoptotic myocardium was observed by means of immunohistochemistry and analysed by image analysis system. Results In both ischemia and reperfusion groups morphologic features of apoptotic myocardium were observed by transmission electron microscopic and the apoptotic cardiocytes were detected by the TdT mediated dUTP nick end labeling (TUNEL) staining. However, the apoptotic DNA ladder was observed only in the 2 hour reperfusion group. The reperfusion group showed a decrease in OD value of the Bcl 2 protein( P

Objective To investigate the influence of intraoperative posture intervention on drainage in patients after gynecological laparoscopic surgery. Methods A total of 1250 patients who were scheduled for gynecological laparoscopic surgery including laparoscopic-assisted salpingoplasty,oophorocystectomy,ectopic pregnancy,vaginal hysterectomy,myomectomy and appendectomy were randomly divided into two groups. The patients' posture was changed from Trendelenburg position to level lithotomic position during suction by the circulating nurses in the experimental group,while after surgery in the control group. The volume and time of drainage,and the length of stay after surgery were compared between the two groups. Results The volume and time of drainage,as well as the length of stay after surgery had significant differences between the two groups (P<0.05). Conclusions Intraoperative posture intervention is helpful for the treatment effect of drainage after gynecological laparoscopic surgery.
