Objective To compare the advantages of three-dimensional(3D) and two-dimensional(2D) ultrasound in embryo transfer. Methods A total of 319 patients accepted embryo transfter were included in this study. 2D and 3D ultrasound were used to investigate the uterine cavity and transfer distance from the fundus (TDF),respectivly. They were divided into four groups according to TDF difference(D-TDF) between 2D and 3D ultrasound(group of DTDF<3mm,group of DTDF3～5mm,group of 6～9 mm,group of DTDF≥10 mm. Pregnancy outcomes among the four groups were compared. Results Of the 319 patients, 41 were observed to have abnormal uterine cavity. For 140 patients, the TDF measured by 2D ultrasound were different from that measured by 3D ultrasound. Clinical pregnancy rate and implantation rate were found lowest in group of TDF≥10 mm mm (7.7% vs 34.1%,38.1% ,40.0% and 3.6% vs 18.2% ,21.2% ,20.0%, P <0.05). Conclusions 2D ultrasound is limit and deficient for embryo transfer, especially for the visualization of uterine cavity and location of catheter tip, however, it may be better achieved with 3D ultrasound. It is helpful to use the 3D ultrasound to place the catheter tip accurately and improve the pregnancy rate of embryo transfer.

This study aims to establish a method to determine the serum acetaminophen concentration based on diazo reaction, and apply it in the gastric emptying evaluation. Theoretically, acetaminophen could take hydrolysis reaction in hydrochloric acid solution to produce p-aminophenol, which could then take diazo reaction resulting in a product with special absorption peak at 312 nm. Then the serum acetaminophen concentration and recovery rate were calculated according to the standard curve drawn with absorbance at 312 nm. ICR mice were given a dose of acetaminophen (500 mg x kg(-1)) by gavage and the serum acetaminophen was dynamically measured through the diazo reaction. Besides, ICR mice were subcutaneously injected with the long-acting GLP-1 analog GW002 before the gavage of acetaminophen, and serum acetaminophen concentration was measured as above to study how GW002 could influence the gastric emptying. The data showed acetaminophen ranging from 0 to 160 μg x mL(-1) could take diazo reaction with excellent linear relationship, and the regression equation was y = 0.0181 x +0.0104, R2 = 0.9997. The serum acetaminophen was also measured with good linear relationship (y = 0.0045 x + 0.0462, R = 0.9982) and the recovery rate was 97.4%-116.7%. The serum concentration of acetaminophen reached peak at about 0.5 h after gavage, and then gradually decreased. GW002 could significantly lower the serum acetaminophen concentration and make the area under the concentration-time curve (AUC) decrease by 28.4%. In conclusion, a method for the determination of serum acetaminophen based on the diazo reaction was established with good accuracy and could be used in the evaluation of gastric emptying.

AIM: To investigate the effects of auricularia auricular polysaccharide (AAP) on chronic cerebral ischemia injury in rats. METHODS: The chronic cerebral ischemia mode1 was made by permanent middle cerebral artery occlusion (MCAO) on the right side. AAP at different doses (50 mg/kg and 100 mg/kg) was intragastrically administered at the onset of ischemia and in the following days after operation, once a day for 4 weeks. After 4 weeks of MCAO, Morris water maze test was introduced to examine the learning and memory functions. Nissl staining was performed to detect the survival neurons in hippocampal slices. Level of malondialdehyde (MDA) and the activity of superoxide dismutase (SOD) in brain tissue were measured. RESULTS: Rats treated with AAP showed a shorter escaping latency in spacial navigation test because the AAP treated rats spent less time to find the platform in spatial probe test. More survival neurons in hippocampal slices were observed from AAP treated rats. Also, the MDA level in brain tissue was reduced and SOD activity in brain tissue was increased in the AAP treated rats with MCAO. CONCLUSION: AAP protects rats from chronic brain ischemic injury, in which its anti-oxidative effect might be involved.

Objective To investigate the incidence of and clinical factors influencing neonatal birth defects from different assisted reproductive technology. Methods Between October 1998 and December 2006,1271 newborns from mothers treated by in vitro fertilization techniques [ including in vitro fertilization (IVF), intracytoplasmic sperm injection (1CSI) and thaw embryo transfer (Thaw-ET) ] matched with 269 newborns from mothers treated by artificial insemination were enrolled in Reproductive Medicine Center in First Hospital Affiliated to Zhengzhou University. Their medical information was analyzed retrospectively to compared neonatal characteristics, the incidence of birth defect and anomalous organs involved between in vitro fertilization group and artificial insemination group. Results In group of in vitro fertilization, those newborns with low birth weight from IVF, ICSI and Thaw-ET were 20. 0% ( 134/671 ), 22. 4% (92/410), 18.9% (36/190)respectively, which were more than 11.5% (31/269) cases in group of artifical semination with statistical significance (P < 0. 05 ). The rates of multiple pregnancy of 23.8% ( 160/671 ), 25.4% (104/410) ,21.1% (40/190) in subgroup of 1VF, ICSI and Thaw-ET were significantly higher than 10. 0% ( 27/269 ) in group of artifical insemination( P < 0. 05 ). The rate of macrosomia in group of in vitro fertilization was significantly lower than that of artificial insemination group (3.9% vs 8. 2%, P <0.05). However, the incidence of birth defect involved in various organs did not show significant difference between two groups ( P>0.05 ). Conclusions The incidence of multiple pregnancy demonstrated obviously increasing trends born with various In Vitro Fertilization techniques, which pave the way to high risk pregnancy. However, the incidence of newborn birth defect was not increased significantly. Thus, to lower occurrence of multiple pregnancy was the key approach to obtain neonates health.

It is important for cardiac therapy devices such as the automated external defibrillator to discriminate different cardiac disorders based on Electrocardiogram analysis. A phase space analysis based algorithm is proposed to detect cardiac arrhythmias effectively. Firstly, the phase space of the signal is reconstructed. Then from the viewpoint of geometry and information theory, the distribution entropy of the point density in the two-dimensional reconstructed phase space is calculated as the features in the further classification. Finally the nearest-neighbour method based on Mahalanobis distance is used to classify the sinus rhythm (SR), supraventricular tachyarrhythmia (SVTA), atrial flutter (AFL) and atrial fibrillation (AF). To evaluate the sensitivity, specificity and accuracy of this proposed method in the cardiac arrhythmias classification, the MIT-BIH arrhythmias database and the canine endocardial database are studied respectively. Experiment results demonstrate that the proposed method can detect SR, SVTA, AFL and AF signals rapidly and accurately with the simple computation. It promises to find application in automated devices for cardiac arrhythmias therapy.
