ABSTRACT
【Objective】 To investigate the current situation concerning volume control of red blood cells in additive solution produced by blood service in Chongqing, and to lay a foundation for promoting the homogenization of preparation process of red blood cells in additive solution. 【Methods】 A questionnaire was designed to investigate the factors related to the preparation of red blood cells in additive solution. The questionnaire was sent by Chongqing Association of Blood Transfusion via E-mail to 18 blood services in the city, and the collected data was sorted, revised and analyzed by research team. 【Results】 A total of 18 blood services(including 1 blood center + 1 sub-center, 6 central blood stations and 11 central blood banks) returned the questionnaires. The results showed that there were differences among blood services across Chongqing, regarding the centrifugal parameters during preparation, the operation mode and monitoring situation of the capacity control during preparation, and the formulation of the capacity standard of red blood cells in additive solution etc. 【Conclusion】 The preparation process of red blood cells in additive solution, produced by Chongqing blood services, should be further standardized, and the capacity control method of this product in Chongqing should be gradually unified to achieve regional homogeneity and to ensure blood safety.
ABSTRACT
Objective To investigate the clinical efficacy of Kirschner wire,reconstruction plate and locking compression plate internal fixation in the treatment of Robinson type 2A and 2B midshaft clavicle fracture.Methods One hundred and fifty patients with midshaft clavicle fracture in the hospital from August 2006 to August 2015 were selected and divided into the group A,B and C.The group A adopted Kirschner wire,group B adopted the reconstruction plate and group C adopted the locking compression plate internal fixation.Then the incision length,operative time,intraoperative blood loss,fracture healing time,postoperative Constant-Murley scores and DASH scores and postoperative complications incidence rate were compared among the three groups.Results The incision length,operative time and intraoperative blood loss in the group A and C were significantly better than those in the group B(P＜0.05).The fracture healing time,postoperative activity,muscle strength and daily life score,postoperative complications incidence rate,postoperative DASH score in the group C were significantly better than those in the group A and B(P＜0.05).Conclusion The locking compression plate in the treatment of Robinson type 2A and 2B midshaft clavicle fracture can effectively reduce the surgical trauma,shortens the fracture healing time and decreases the postoperative complications.
ABSTRACT
Objective To explore the change of Doppler velocity waveforms in the fetal main pulmonary artery in patients with early onset severe preeclampsia and to assess its value in fetal lung maturity.Methods A prospective study was conducted to analyze fetal main pulmonary artery velocity waveforms parameters including acceleration time(AT),ejection time(ET),acceleration time/ejection time (AT/ET),peak systolic velocity (PSV) in 30 cases of pregnant women with early onset severe preeclampsia.According to neonatal outcome,these cases were divided into respiratory distress syndrome (RDS) group (18 cases) and non-RDS group (12 cases).Each group was compared with 54 cases and 36 cases that were normal and had corresponding gestational age separately.Doppler parameters were compared between these two groups and their corresponding normal control groups.Results Gestational age at sonographic examination,gestational age at delivery and birth weight of neonates in RDS group were significantly lower than those in non-RDS group(all P ＜0.001).The value of AT,ET,AT/ET,PSV were lower in RDS group than those in gestational age-matched control group(all P ＜0.05),while there were no significant difference between non-RDS group and gestational age-matched control group(all P ＞ 0.05).Conclusions Doppler ultrasound monitoring fetal main pulmonary artery velocity waveforms to evaluate fetal lung maturity in patients with early onset severe preeclampsia has clinical application value.
ABSTRACT
ObjectiveTo explore the effect of risk factors for coronary heart disease on the occurrence of heart failure in women with coronary heart disease. MethodsThree hundred and twenty-eight cases with coronary heart disease including 196 male patients (male group) and 132 female patients(female group) were selected. The risk factors of coronary heart disease including age, high blood pressure,diabetes, blood fat, plasma fibrinogen and blood uric acid were compared, all the patients were followed up for 1-3 years, the occurrence of heart failure was observed between the two groups, the level of blood uric acid was compared between patients with or without heart failure in female group. ResultsThe level of triacylglycerol, plasma fibrinogen and blood uric acid in female group was higher than that in male group (P ＜ 0.05 ). Followed up for 1-3 years, the occurrence of heart failure in female group was higher than that in male group[27.27％ (36/132) vs. 16.84％ (33/196)]. The level of blood uric acid in female group with or without heart failure was(368.85 ± 78.60) μ mol/L and(336.63 + 69.65 )μ mol/L, there was significant difference between the both (P ＜ 0.05 ). ConclusionsThe risk factors for coronary heart disease are the important dement in female coronary heart disease with heart failure, and blood uric acid is the alone risk factor. Through early monitoring the blood uric acid etc and intervention, the progress of the disease will slow.
