Objective To explore the value of ultrasonographic on fetal limb deformities in prenatal diagnosis by using systemat-ic continuous sequence approach(SCSA) Methods During the period of January 2008 to April 2012 ,SCSA with color doppler ultra-sonography was used to screen 41 460 pregnant women in order to observe the four limbs of the fetus .And compared with the limbs of the fetus after birth or induction of labor .Results There were 99 cases of fetal limb deformities in 41 ,460 pregnancy ,of which 31 cases of femoral abnormalities were found by routine ultrasound ,92 cases of fetal limb deformities were found by SCSA .68 cases of fetal limb deformities were detected by SCSA in 19- <27 weeks of gestation ,accounting for 73 .91% of detection limb deformi-ties .In the 99 cases of fetal limb deformities ,varus feet were the most was (27 cases) ,followed by short limbs deformity (24 cases) , limbs compound malformations(11 cases) ,limb posture abnormalities(10 cases) ,part of the amputation(10 cases) and multiple fin-gers/toes(7 cases) .Conclusion SCSA with color doppler ultrasonography is an effective method for prenata screening of fetal limb deformities .

Objective Preoperative autologous blood donation ( PABD) may reduce the need for allogeneic blood , but it may also cause a short massive blood loss in pregnant women , and its fetal and maternal safety has to be adequately assessed .This study was to evaluate the feasibility and safety of PABD for pregnant women and their fetuses . Methods A prospective observational study was conducted among the women who met the inclusion criteria and gave birth in Nanjing Drum Tower Hospital between January and December 2013 .According to the clinical validation of risk stratification criteria for peripartum hemorrhage of California 2013 , the ca-ses were classified into a low-, a medium-, and a high-risk group.Data on blood donation procedures , obstetric outcomes, and blood transfusions were collected after delivery for analysis . Results Totally, 92 pregnant women accomplished 115 blood donations .The median volumes of the donated blood were 300, 300, and 400 mL in the low-, medium-, and high-risk groups, respectively ( P>0.001).There were no significant changes in HR , SBP and SpO2 during the blood donation procedures (P>0.05) except for the fall of diastolic blood pressure by an average of 3.4 mmHg (P<0.05) at 5 minutes after blood collection, which was restored to normal later.Non-reassuring fetal heart rate patterns were not found in any of the cases .The levels of HB and HCT were remarkably lower af-ter donation than before it (P<0.05) but restored to normal before delivery in the PABD cases who donated once only (P>0.05), which were similar to those in the cases who donated twice , with no significant differences before and after the donation (P>0.05). Homologous blood transfusion was performed for 5 cases (17.9%) in the high-risk group, with the volume of blood loss >2000 mL in all the cases.All the newborns survived without asphyxia and there was no perinatal death . Conclusion PABD can provide timely autologous whole blood donation for pregnant women .Under strict management , PABD is feasible and safe for pregnant patients who are at a high risk for massive blood loss during delivery or have a rare type of blood no readily available .

For the quality management system of herbal medicines, intermediate and finished products it exists the " short board" effect of methodologies. Based on the concept of process control, new strategies and new methods of the production process quality control had been established with the consideration of the actual production of traditional Chinese medicine an the characteristics of Chinese medicine. Taking Banlangen granule as a practice example, which was effective and widespread application, character identification, determination of index components, chemical fingerprint and biometrics technology were sequentially used respectively to assess the quality of Banlangen herbal medicines, intermediate (water extraction and alcohol precipitation) and finished product. With the transfer rate of chemical information and biological potency as indicators, the effectiveness and transmission of the above different assessments and control methods had been researched. And ultimately, the process quality control methods of Banlangen granule, which were based on chemical composition analysis-biometric analysis, had been set up. It can not only validly solute the current status that there were many manufacturers varying quality of Banlangen granule, but also ensure and enhance its clinical efficacy. Furthermore it provided a foundation for the construction of the quality control of traditional Chinese medicine production process.
