Diagnosis judgment values of trimester ultrasound screening for simple single umbilical artery fetal malformation / 中国综合临床

Objective To investigate the diagnosis judgment values of trimester ultrasound screening for simple single umbilical artery fetal malformation.Methods From January 2011 to January 2015,selected the 15-28 weeks pregnant singleton pregnancies in Shunyi Hospital of Beijing Chinese Medicine Hospital for system fetal ultrasound,in which the single umbilical artery group of 50 patients,50 cases of healthy pregnant women (control group),the two groups were carried ultrasound screening with single umbilical artery flow spectrum analysis,and observed the prognosis.Results The single umbilical artery fetal bladder after abdominal oblique horizontal cross-section of the umbilical artery bypass saw one side of the bladder,and there were 24 patients the malformations with the incidence rate was 48.0％.In the two groups can be clearly demonstrated umbilical artery condition,but the umbilical artery pulsation index(PI),arterial resistance index (RI) and peak valley ratio of umbilical artery blood flow velocity (S/D) value in the single umbilical artery group were 1.02±0.17,0.66±0.06 and 3.08 ±0.57,significantly higher than those of the control group (0.75 ± 0.21,0.53 ± 0.08,2.11±0.27;t=7.298,11.874,15.983,P＜ 0.05).In the single umbilical artery group,there were 32 patients of abortion,10 patients of birth were,8 patients ogpregnancy.Perinatal death in 8 cases,the mortality rate was 16.0％,the single umbilical artery fetal malformations of perinatal mortality was significantly higher than that of children with simple single fetal umbilical artery (x2 =9.333,P ＜ 0.05).Conclusion Trimester ultrasound screening for single umbilical artery combined with simple two-dimensional ultrasound and umbilical arteryblood flow velocity conditions can improve fetal malformations value judgment,provide a reliable detection method to reduce oerinatal mortality.

The difference between oversea predicted values and Chinese healthy adult measurements of spirometry in shenyang / 中国实用内科杂志

Objective To evaluate if the difference between oversea predicted values and healthy adult measurements of spirometry in shenyang.Methods 287 healthy adult volunteers underwent pulmonary function test.The measurements of spiromenty of 230 selected objects were compared to conventional oversea predicted values.Results In male group(154 objects),the measured values were as follows:VC(4.4?0.7)L,FVC(4.3?0.7)L,FEV1(3.5?0.6)L,FEF25%～75%(3.6?1.1)L/s,PEF(7.1?1.9)L/s,IC(2.8?0.7)L,respectively.In female group(76 objects),the measured values were as follows:VC(3.1?0.7)L,FVC(3.1?0.7)L,FEV1 2.5?0.6(L),FEF25%～75%(2.6?0.9)L/s,PEF(5.0?1.4)L/s,IC(2.1?0.7)L respectively.The measurements were 2%～26% and 2%～21% lower than the predicted values in male and female respectively.The major compared values had significant difference.Conclusion The major measured values of spirometry in healthy adult in shenyang were significantly lower than the oversea predicted values.Knudson or ECCS regression equations with appropriate correction factor were suggested to use in shenyang.

Preparation of Multiple Emulsion Type Gel for Paeonol / 中成药

Objective: To prepare a new multiple emulsion type gel of paeonol. Methods: Span 80 and Triethanolamine were used as emulsifiers of the multiple emulsion, sodium carboxymethyl cellulose (CMC Na) and polyvinyl alcohol (PVA 124) were substrates of mixed hydrophilic gel. Results: The multiple emulsion type gelprepared possessed the merits of high concentration of drug, uneasily volatilizating, persistentation and good film forming. Conclusion: The multiple emulsion type gel of paeonel has the sustained release action.
