Objective To evaluate the diagnostic value of magnetic resonance imaging (MRI) on fetal ventriculomegaly identified through prenatal ultrasonography and the outcomes of these newborns were followed up. Methods From March 2006 to July 2008, MRI was performed on 135 pregnant women whose fetuses diagnosed as fetal ventriculomegaly at an average of 32 gestational weeks in Shengjing Hospital Affiliated to China Medical University. Mild ventriculomegaly was defined when the width of unilateral or bilaeral fetal cerebral ventricle triangle was 10-15 mm, moderate ventriculomegaly 16-20 mm and severe ventriculomegaly >20 mm. We introduced the Denver developmental screening test(DDST) to follow-up the mild ventriculomegaly and normal babies, confirmed by MRI, at 6-12 months after birth and a case-control study was conducted. The intelligence and growth of these infants were analyzed. Results (1) Diagnostic rate of fetal ventriculomegaly through MRI: Among the 135 gravidas, 60 (44.4%) showed isolated ventriculomegaly, 5 (3.7%) complicated with ventricular hemorrhage; 12 (8.9%) complicated with agenesis of corpus callosum (ACC) and 2 (1.5%) complicated with cerebellar hypoplasia, while 56 (41.5%) were normal. Seventy-nine cases had fetal ventriculomegaly on MRI and 15.2% (n=12) of them complicated with ACC. (2) Degree of fetal ventriculomegaly on MRI: Among the 60 isolated ventriculomegaly cases, 55 (91.7%) were mild and 5 (8.3%) moderate ones. Among the 5 cases complicated with ventricular hemorrhage, one was mild ventriculomegaly, and 4 moderate or severe cases. Among the 12 cases with ACC, 8(66.7%) were moderate ventriculomegaly and 4 (33.3%) severe cases. The 2 cases with cerebellar hypoplasia were both moderate ventriculomegaly fetuses. (3) Follow-up at 6-12 months after birth : thirty out (case group) of the 55 isolated ventriculomegaly cases, 38 out of the 56 normal babies and 42 babies with normal MRI results were followed up, and the later 80 cases were taken as control. Four infants (13.3%) in the case group and 10 (12.5%) in the control group showed abnormal or suspected results in DDST (P>0.05), the rest babies were all normal. (4) Clinical outcomes of the 79 ventriculomegaly fetuses diagnosed by MRI: thirty mild ventriculomegaly babies and 5 moderate ones were born at term and showed normal at follow ups. However, 7 gravidas were not compliant, 6 pregnancies were terminated, and 12 were last. Three of the 12 cases with ACC continued the pregnancy, and postnatal MRI of the babies showed the same with the prenatal MRI, 8 pregnancies were induced and one was lost. All of the 5 fetuses with ventricufar hemorrhage were induced and the prenatal diagnosis was confirmed by autopsy. One of the 2 fetuses with cerebellar hypoplasia was term delivered and diagnosed as cerebral palsy at the age of 6 months, and the other one was induced. Conclusions MRI is an indispensable complementary diagnostic method for fetal ventriculomegaly diagnosed through ultrasound. The development of intelligence and growth of babies born with mild isolated ventriculomegaly is the same as normal ones.

Objective To evaluate the effects of continuous quality improvement (CQI) management on nutritional status,renal function progression,and compliance of low protein diet in patients with chronic kidney disease (CKD).Methods Totally 115 CKD patients who were regularly followed up in CKD clinic services were recruited in this study.Plan,Do,Check,and Act (PDCA) method was adopted to manage the dietary of these patients for 12 months.The clinical indicators and diet compliance before and after receiving CQI management were compared.Results After receiving the CQI management,the nutritional status of patients was well maintained;meanwhile,the average hand strength and the hemoglobin,serum albumin,total cholesterol,and triglyceride levels showed no significant changes (all P ＞ 0.05).Subjective feelings of patients were improved.The modified Subjective Global Assessment of Nutrition (mSGA) score was decreased from 7.0 (7.0,8.0) to 7.0 (7.0,7.0) (P =0.000).The estimated glomerular filtration rate (eGFR) calculated by formula of modified MDRD was decreased from (40.74 ± 14.49) to (37.94 ± 16.86) ml/(min · 1.73 m2) (P =0.000),and the average descended speed was (2.81 ±7.42) ml/(min · 1.73 m2) per year.The creatinine clearance rate had no statistical difference between pre-and post management (P =0.910),and the average descended speed was (0.19 ± 17.01) ml/min per year.The daily protein intake (DPI) and protein equivalent of nitrogen appearance rate (PNA) were both significandy descended:DPI/kg decreased from (0.79 ± 0.27) to (0.64 ± 0.15) g/ (24 h · kg) (P =0.000),and PNA/kg dropped from (1.02 ± 0.32) to (0.82 ± 0.24) g/ (24 h · kg) (P =0.000).The scores of awareness and compliance of patients on low protein diet were significantly increased after CQI management (P =0.000).Conculsion Applying CQI on dietary and nutrition management in CKD patients can maintain the good nutritional status and improve the compliance of low protein diet.

Objective To investigate the actual cost and benefit of stoma nursing at present as a reference for the improvement of stoma care cost management program. Methods A cross sectional study was carried out in gastrointestinal surgery of a tertiary- level hospital in southwestern China from April 2014 to December 2014. The consumption of intestinal stoma care work, the average monthly income/average monthly working hours ratio and other indicators of stoma care nurse specialist were measured by the step cost allocation method, to investigate the actually cost of a single stoma care service which colostomy patients had received and analyze the gap between actually costs and charge standard of Sichuan Province. Results The directly human cost of stoma care expenses were (22.33 ± 3.66) yuan; working fee expenses were (4.18 ± 0.68) yuan;administrative expenses were (1.87 ± 1.32 ) yuan; research and education expenses were (1.87 ± 1.32 ) yuan; the total cost of investment was (29.14 ± 4.76) yuan, which was much higher than the current charge standard of Chengdu Bureau of Commodity Prices (t=119.50, P <0.05). Conclusions There is a difference between the actual cost and charge standard of stoma care. The situation of low pay to labor is not in line with economic laws, and not conducive to the future development of stoma care speciality.

Tamoxifen and letrozole are two of the most effective pharmaceuticals mainly used in hormonal dependent) breast cancer therapy. A trace analytical method using ultra performance liquid chromatography/tandem mass spectrometry(UPLC-MS/MS) was developed to simultaneously detect these two drugs in both influent) and effluent of municipal sewage treatment plant. Sewage samples were passed through an Oasis HLB cartridge, then an amino solid phase extraction cartridge was connected with Oasis HLB cartridge. Target compounds) was firstly eluted with 6 mL methanol and then 3 mL methanol was used to elute the amino solid phase extraction cartridge, collected and pooled the elutants. After concentration, target compounds were separated) on a BEH C_(18)) column using a gradient elution profile with a mobile phase consisting of 0.1% formic acid aqueous) solution and acetonitrile and detected by an electro spray ionization tandem mass spectrometry with multiple reactions monitoring(MRM). Satisfactory linearity(R~2>0.997) was obtained over the range of 1.0-100 μg/L) and 0.1-100 μg/L for tamoxifen and letrozole, respectively, with limits of quantification(LOQ) of 1.0 and 0.1 ng/L. Mean recoveries of two target compounds(spiked in sewage samples at three concentration levels) ranged from 68.8% to 103.0%, with relative standard deviations(RSD) less than 15%. This method can be applied for the analysis of target drugs sewage samples.
