Objective:To discuss the application effect of quality management of quality control circle (QCC) for reducing re-washing rate of suction aspirator tip in the quality management of medical instrument of hospital.Methods: Through established QCC group to designate one topic, to investigate its current situation and to protocol project plan of quality management. The qualified rate of first washing of 904 suction aspirator tips was analyzed before control management of QCC was implemented, and then series of QCC methods including fishbone diagram were applied to analyze and confirm main factors. The protocol countermeasure, depend on above information, achieved improvement for washing quality of 856 suction aspirator tips after the quality management of QCC was implemented in practice. The re-washing rates of washing quality of suction aspirator tip between before and after QCC was applied were compared.Results: The qualified rate of first washing of 904 suction aspirator tips before the quality management of QCC was implemented was 65.7%, while it was 97.6% for 856 suction aspirator tips after quality management of QCC was implemented. The washing qualified rate of suction aspirator tip after quality management of QCC was applied was significantly higher than that before it was applied (x2=8.429,P<0.05), and the result has achieved the aim that continuous improved quality.Conclusion: The application of quality management of QCC can decrease re-washing rate of suction aspirator tip, and contribute to decrease cost, to increase work efficiency, to strengthen the attention and degree of involvement of staff for work quality. Therefore, the management can fully exert potential of member of quality management of QCC, and enhance washing quality of suction aspirator tips.

Objective To investigate the protective effect of 3-hydroxybutyrate derivate( methyl-3-hydroxybutyrate and ethyl-3-hydroxybutyrate)on the apoptosis of PC12 induced by FBS deficiency. Methods Methyl-3-hydroxybutyrate and ethyl-3-hydroxybutyrate were prepared by chemical degradation. PC12 cells were divided into different groups:medium with FBS as negative control,medium without FBS as positive control,medium with different concentrations of methyl-3-hydroxybutyrate or ethyl-3-hydroxybutyrate without FBS as sample groups. The shape and viability of cells in each group were analyzed by optical microscope and MTT. Results Compared with the negative control,cells in the positive control group demonstrated a large number of apoptosis,smaller and thinner morphology,and lower activity. However,the activity of cells was improved in the sample groups.Low concentration(0. 01 and 0. 001 mg·mL-1)of methyl-3-hydroxybutyrate and ethyl-3-hydroxybutyrate showed a protective effect on cell apoptosis,and 1 mg · mL-1 had the best protection effect. Conclusion High purity methyl-3-hydroxybutyrate and ethyl-3-hydroxybutyrate can be produced by chemical method,and both chemicals present good effect on protecting the PC12 from apoptosis.

Objective To evaluate the levels of plasma coupling factor 6(CF6) and cytochrome C(Cyt-c) in neonatal sepsis,and to explore the clinical significance in neonatal sepsis.Methods A total of 88 neonates admitted to Hunan Children's Hospital from January 2015 to April 2015 were collected.Neonates were divided into non-sepsis group(n=42) and sepsis group(n=46).According to the severity of infection,the non-sepsis group was further divided into non-infection group(n=20) and common infection group(n=22);the sepsis group was further divided into general sepsis group (31 cases,no organ failure) and severe sepsis group (15 cases,combined with multiple organ failure).Femoral venous blood was collected in all patients before the use of antibiotics after admission.The levels of Cyt-c and CF6 in plasma were measured by ELISA,and the levels of C-reactive protein(CRP),procalcitonin (PCT) were measured.The changes of CF6 and Cyt-c between these groups were compared,and the sensitivity and specificity with the traditional sepsis index (CRP,PCT) were analyzed.The correlation between the levels of CF6,Cyt-c and neonatal critical illness score was analyzed.Results (1)In sepsis group,the levels of CF6 and Cyt-c[(109.7±8.9)pg/ml and (44.5±4.9)ng/ml] were significantly higher than those in the non-sepsis group[(46.3±6.0)pg/ml,(31.8±6.7)ng/ml,P<0.01,respectively].(2) In the non-infection group,common infection group,general sepsis group and severe sepsis group,the levels of CF6 were (32.1±8.9)pg/ml,(59.3±7.2)pg/ml,(79.3±5.9)pg/ml,and (172.6±6.1)pg/ml,respectively;the levels of Cyt-c were (29.3±8.6)ng/ml,(35.4±4.1) ng/ml,(43.1±5.9) ng/ml,and (44.5±5.9)ng/ml,respectively.The differences between these groups were significant(P<0.01).(3)The receiver operating characteristic curve showed that the sensitivity and specificity of CF6 were 0.761,0.732,and the Cyt-c were 0.739,0.714.(4)Cyt-C and CF6 were negatively correlated with the neonatal critical illness score(r=-0.599,P<0.001;r=-0.337,P<0.01).Conclusion The levels of CF6 and Cyt-c increase in neonatal sepsis.The damage of mitochondria may be one of the pathological mechanisms in neonatal sepsis.The levels of CF6 and Cyt-c were closely related to the severity of neonatal sepsis.

The endometrial antigens from human endometrium were purified by collagenase (Type I), 250um, 40um, sieves and affinity chromatography. Indirect ELISA was used to detect antiendometrial antibodies (EMAb). The findings showed that the positive rates of EMAb in this assay were 43.4% (infertile, n=129), 37.1% (abortion, n=113), 6.7% (middle and old man, n = 120), 3.8% (pregnant woman, n = 52) and 0% (male, n = 43), respectively.

Objectives: To clarify the diagnostic value of sTFR and its compound parameters sTFR/SF, sTFR/logSF in the differential diagnosis of IDA, ACD and CDID. Methods: Forty nine anemia patients were classified into IDA, ACD and CDID by clinical presentations and the laboratory results. The serum concentration of sTFR was detected by ELISA. The difference of sTFR, sTFR/SF, sTFR/logSF and routine parameters in the three groups and the correlation among sTFR and routine parameters were analyzed. Using ROC curve, the diagnostic value of these parameters in the differential diagnosis of the three diseases were compared. Results: The serum concentration of sTFR in the IDA, ACD and CDID were (50.8?8.2)nmol/L, (33.5?6.9)nmol/L and (22.7?9.9)nmol/L,respectively. The differences among three groups were significant( P

Objective To analysis the clinical outcome at discharge and its risk factors of extremely preterm infants.Method To retrospectively analysis the clinical outcome at discharge and it's risk factors of extremely preterm infants (less than 28 weeks gestation) admitted from September 2008 to August 2014 in our Hospital.Result A total of 179 cases were enrolled.Survival rate was 59.2% (106/179).Unfavorable outcome rate was 74.3% (133/179),among them 73 cases died.The top five causes of death were severe bronchopulmonary dysplasia (BPD) (28 cases),Ⅲ ~ Ⅳ o intraventricular hemorrhage (IVH) (19 cases),sepsis (16 cases) and necrotizing enterocolitis (NEC) (6 cases).Among the 60 survivals with unfavorable outcomes,35 cases had either severe neurologic or ophthalmological sequela,and 25 cases had severe pulmonary sequela.Univariate analysis showed that,comparing with improved group,unfavorable outcome group had higher rates of not receiving prenatal steroids,placental abruption,male,small for gestation age,resuscitation with chest compression,admission age older than 72 hour,severe respiratory distress syndrome (RDS),without pulmonary surfactant (PS) usage,mechanical ventilation beyond 2 weeks and sepsis (P < 0.05).Logistic regression analysis showed that those without prenatal steroids (OR =9.402,P =0.002),small for gestational age (OR =8.271,P =0.018),resuscitation with chest compression (OR =6.325,P =0.023),admission age older than 72 hour (OR =4.174,P =0.028) were independent risk factors for unfavorable outcome of extremely premature at discharge.Conclusion Extremely preterm infants have a higher rate of unfavorable outcome at discharge.Avoid small for gestational age,transfer properly and in time both in utero and after birth,and conduct prenatal steroids could improve their clinical outcome at discharge.
