ABSTRACT
Identification of the risk factors for conversion to cesarean section during labor can significantly improve the mother and infant outcomes. Though advocated by the International Society of Ultrasound in Obstetrics and Gynecology (ISUOG), intrapartum ultrasound is not widely practiced in managing labor progress. The Obstetrics and Gynecology Center of Zhujiang Hospital of Southern Medical University has carried out intrapartum ultrasound in recent years. We summarize the clinical key point and the significance of measuring the major sonographic parameters during labor and illustrate the role of occiput-spine angle, a new sonographic index, in predicting fetal head descent during the first stage of labor.
ABSTRACT
<p><b>OBJECTIVE</b>To define the optimal development time of micro-computed tomography (micro-CT) venography in cervical cancer patients and establish 3D CT-based digital pelvic model of the patients.</p><p><b>METHODS</b>Thirty patients with cervical cancer stratified by FIGO surgical staging underwent micro-CT scanning of the arterial phase and the venous phase with a delay time of 70, 90 and 120 s. The images were interpreted independently by two experienced radiologists to define the optimal development time in venous phase and establish the imaging diagnosis. Based on the pelvic CT scan data, we segmented the images using the abdominal medical image-3D visualization system followed by 3D image reconstruction to establish the 3D digital pelvic model using FreeForm Modeling System to modify the reconstructed images.</p><p><b>RESULTS</b>The optimal images were obtained by scanning with a 90-sec delay time. Micro-CT was not sensitive to IB1 phase or earlier phases (1/5), but efficient in advanced stages (≥IB2 phase). In our cases, 25 were diagnosed by micro-CT with a diagnostic accuracy of 64%. Based on these CT data, the pelvic 3D model covering the main organs, vessels, cervical neoplasm, and supplying vessels of the tumor in the pelvic cavity were successfully reconstructed to allow spatial observations of the uterus and the neighboring organs.</p><p><b>CONCLUSION</b>The 3D digital pelvic model reconstructed provides a means for staging cervical cancer and facilitates further surgical simulation studies.</p>

Objective To explore the relation of the infantile acute upper respiratory tract infection(AURI) with myocardial injury.Methods Creatine kinase (CK) and its isoenzyme(CK-MB),lactate dehydrogenase(LDH),asparatic acid transminase (AST) were tested with the fully automatic analyser and electrocardiogram(ECG) were examined with AURI in 86 cases as experimental group and 30 cases of health infants as control group.Results The abnormal rates of CK,CK-MB,LDH,AST and ECG in the AURI group were higher than those of the control group.Conclusions There is different degree of myocardial injury in some children with AURI, the clinical doctor should pay more attention in the AURI cases companied with the myocardial injury and to prevent myocardial injury complicaton in these cases .

ABSTRACT
Objective:To investigate the blood lipid status and its variation regularity of a population of teaching staff in order to provide evidence for preventing hyperlipidemia.Method:Lipid indexes such as TC,Triglyceride(TG),LDL-C and HDL-C are inspected of a group of teaching staff over 40 years old in some certain university,and data statistics and analysis are conducted.Conclusion:Main behaviors of male and female teaching staff's hyperlipidemia are high TG and high LDL-C.Special focus should be put on blood lipid's variation level of middle aged males around 40 years old,periodical clinical monitoring should be done for female teaching staff over 50 years old.Medical information instruction on the prevention and control of high blood lipid should be strengthened in order to realize the unity of self control and social control.
