In this study, hollow fiber membrane extraction combined with ambient ionization mass spectrometry ( AMS) was developed for the simultaneous determination of 7 perfluorinated compounds ( PFCs) in aqueous solution, including perfluoroheptanoic acid ( PFHpA ) , perfluorooctanoic acid ( PFOA ) , perfluorooctane sulfonate acid ( PFOS ) , perfluorononanoic acid ( PFNA ) , perfluorodecanoic acid ( PFDA ) , perfluoroundecanoic acid ( PFUdA) , and perfluorododecanoic acid ( PFDoA) . PFCs were detected in negative ion mode using selective reaction monitoring ( SRM) mode. The extraction time and the pH value of extraction solution were optimized. 13 C4-PFOS and 13 C4-PFOA were used as internal standards for quantitative analysis. The method showed good linearity with correlation coefficient values ( r2 ) greater than 0. 991 for the seven target PFCs. With the exception of PFHpA, the limit of detection ( LOD) for other six PFCs was within ranges from 0. 8 to 2. 7 ng/L while the limit of quantitative (LOQ) was from 2. 7 ng/L to 8. 9 ng/L. The enrichment factor of five PFCs was more than two hundred. The developed method was applied to detect the seven PFCs in tap water and Pearl River water, and they were all not detected. The recoveries were within the ranges of 88. 5%-108. 3% and 94. 2%-116. 7% when 40 ng/L and 400 ng/L PFCs were spiked into tap water, respectively. In terms of the Pearl River water, the recoveries were within the ranges of 75. 0%-102. 6% and 81. 2%-97. 6% when 40 ng/L and 400 ng/L PFCs were spiked, respectively.

Objective: To observe the effect of electroacupuncture (EA) of "concurrent treatment of the brain and heart" on angiogenesis and cortical vascular endothelial growth factor (VEGF) and brain-derived neurotrophic factor (BDNF) in rats with focal cerebral ischemia, and to explore the mechanism of EA in cerebral ischemia treatment. Methods: A total of 108 Sprague-Dawley rats, 27 rats were randomly selected as the sham-operation group, and the rest rats received the right middle cerebral artery occlusion operation for model preparation firstly, and then were divided into a model group, a traditional acupoint group, and a concurrent treatment of the brain and heart group, with 27 rats in each group. In the sham-operation group, only the carotid artery was isolated. EA at Shuigou (CV26), Quchi (LI11), Hegu (LI4), and Zusanli (ST36) in the traditional acupoint group, and EA at Fengfu (GV16), Baihui (GV20), Xinshu (BL15), and Neiguan (PC6) in the concurrent treatment of the brain and heart group were performed 4 h after the operation, once a day, for 14 consecutive days. Rats in the sham-operation group and the model group were identically fixed without any treatment. Before and after treatment, the modified neurological severity score (mNSS), regional cerebral blood flow (rCBF), and CD34 positive expression by immunohistochemistry were measured. The positive protein expression levels of VEGF and BDNF were detected by immunofluorescence, and the mRNA expression levels of VEGF and BDNF were detected by quantitative reverse transcription-polymerase chain reaction (qRT-PCR). Results: Compared with the sham-operation group, the mNSS, rCBF, and ischemic side cortical micro-vessel density (MVD) decreased, and the protein and mRNA expression levels of VEGF and BDNF increased in the model group (P<0.01). Compared with the model group, the mNSS of the two EA groups decreased, and the mNSS of the concurrent treatment of the brain and heart group was lower than that of the traditional acupoint group on the 14th day (P<0.05). Compared with the model group, the rCBF in the two EA groups increased, and the rCBF reached the highest on the 14th day (P<0.05 or P<0.01), and the rCBF in the concurrent treatment of the brain and heart group was higher than that in the traditional acupoint group (P<0.05); the MVD of the two EA groups was higher than that of the model group, and the MVD of the concurrent treatment of the brain and heart group was higher than that of the traditional acupoint group on the 7th and 14th days (P<0.05 or P<0.01). Compared with the model group, the protein and mRNA expression levels of VEGF and BDNF in the two EA groups increased (P<0.01). The VEGF expression level was the highest on the 7th day in the concurrent treatment of the brain and heart group (P<0.05), and the BDNF expression level was higher on the 7th and 14th days than on the 3rd day (P<0.05). The mRNA expression levels of VEGF and BDNF in both EA groups reached the highest on the 7th day (P<0.05 or P<0.01). Conclusion: EA therapy can up-regulate the VEGF and BDNF expression levels and increase the rCBF in the cortex of rats with focal cerebral ischemia, which may be one mechanism of EA in the cerebral ischemia treatment. The therapeutic effect is accumulated with the effective time, and the concurrent treatment of the brain and heart group is superior to the traditional acupoint group in promoting angiogenesis.

Objective To assess the clinical significance of fetal pyelectasis and its changing in utero. Methods One hundred and ninty-seven isolated pyelectasis cases were retrospective reviewed from Jan 2012 to Jul 2014.Isolated pyelectasis was defined as a renal pelvis anteroposterior diameter (RPAPD)of ≥5 mm without other fetal anomaly in second trimester.Persistent or progressive pyelectasis was defined as a RPAPD of ≥10 mm before delivery.They were divided into two groups according to the size of renal pelvis in second trimester:group A (RPAPD 5 - 10 mm)and group B (RPAPD ≥ 10 mm).As the same,there were two groups after 32 weeks of gestation:group C (RPAPD < 10 mm)and group D (RPAPD ≥ 10 mm).Results Totally 1 54 cases were followed up.There were 1 88 cases (95.4%)in group A,with 41 cases lost,141 cases (95.9%)RPAPD <10 mm,6 cases (4.1 %)RPAPD ≥10 mm before delivery.There were 9 cases (4.6%)in group B,with 2 cases lost,remained 7 cases RPAPD ≥ 10 mm before delivery. Conclusions Although most of the fetuses with RPAPD 5 - 10 mm in second trimester will remain the same or resolved before delivery,those with RPAPD ≥ 10 mm may persistent or progress.Prenatal assessment of fetal renal pelvis may provide properly consultation.

Objective To establish the reference ranges for fetal cardiac axis in the mid-second trimester and to evaluate the use of fetal cardiac axis in prenatal diagnosis.Methods 6744 unselected singleton pregnancies were enrolled from September 2008 to October 2010.Routine screening scan of second trimester and fetal echocardiography were performed at 18- 23+6 weeks gestation.Fetal cardiac axis was measured on the four-chamber view of the heart.Results The 6744 fetuses had a mean cardiac axis of (37.03 ± 6.10)°,ranging from 9.80° to 102.41°. Using above or below 95％ range of population (26.63° -49.40°) as a cut-off,there were significant difference of cardiac axis between normal group [(36.96 ± 5.91)°,P ＜0.01] and the group with heart defects [(43.12 ± 15.67)°,P ＜0.01],the group with intrathoricic anomalies or abdominal wall defect [(51.74 ± 15.97)°].ConclusionsThe reference ranges of fetal cardiac axis for local population in mid-second trimester may helpful for detecting congenital defects.Presence of an abnormal cardiac axis in the fetuses is associated with a substantial risk of congenital heart disease and/or other extra cardiac defects.

Objective: To evaluate the feasibility and efficacy of naked-eye assessment (NA) of ultrasound-guided fine needle aspiration cytology(US-FNAC) smears, which was performed by a trained non-cytological physician. Methods: A total of 290 smears of FNAC in 143 thyroid nodules were used to evaluate the value of NA by an assistant with more than two years experience of intervention with ultrasound guidance. NA results such as the background of smear (bloody/non-bloody), thickness (thick/thin), as well as the contents (granulated/non-granulated) were recorded. The correlation between NA and cytological results was analyzed. Number of cells under microscopy, the non-diagnostic rate, and the significance between benignity and malignancy with different features of specimens were compared. Results: There was no significant difference between the NA background and cytological findings(P=0.707, 0.200, 0.705, respectively). There was significance in number of cells, non-dianostic rate between thick and thinner specimens (P=0.000, 0.001, respectively). However, there was no significance in benignity and malignancy between thick and thinner specimens (P=0.385). There was significance in cytology results between the granulated and non-granulated smears(all P=0.000). The difference was found in 51.1% of the smears with granulates were malignancy in cytology. While 77.8% of the non-granulated smears were ultimately diagnosed as benignity. Conclusions The NA could be performed by a trained non-cytological physician and contribute to preliminary predictions of cytology effect.

Objective To explore the effects of collaborative nursing model on preventing anterior resection syndrome (ARS).Methods From July 2016 to April 2017, 130 patients with low rectum anus preserving operation in Anhui Provincial Hospital were selected. All of the patients were divided into observation group (n=69) and control group (n=61) according to hospital stay. Patients of control group were treated with routine nursing. Patients of observation group accepted intervention with the collaborative nursing model. The recovery of anal function and life quality of patients after surgery in two groups were evaluated with the Low Anterior Resection Syndrome (LARS) and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core-30 (EORTC QLQ-C30) respectively.Results Three months after surgery, the score of LARS and score of the general health of QLQ-C30 was (25.49±1.67) and (79.87±4.78) respectively in observation group, higher than those in control group with significant differences (t=2.753, 3.376;P<0.05). Conclusions The implementation of collaborative nursing model can improve the recovery of anal function and life quality of rectum cancer patients as well as effectively prevent the incidence of ARS.
