A method was developed for the determination of bifenthrin in tea by ultra performance convergence chromatography ( UPC2 ) . The samples were extracted with petroleum ether and cleaned up with Waters Sep-Pak:Carbon NH2 , and then detected by UPC2 . The mobile phase was the mixture of supercritical CO2 and acetonitrile at a flow rate of 1. 5 mL/min. The separation was conducted on a column of ACQUITY UPC2 TM BEH (100 mmí3. 0 mm,1. 7 μm). The UV detector was set at a wavelength of 220 nm. The detection limit was 20 μg/L. The linear range of bifenthrin was 0. 32-10. 30 mg/L. The recoveries ranged from 88. 7% to 98. 2%. The relative standard deviations (RSD) were from 1. 4% to 2. 8%. The result showed that the UPC2 was more efficient, rapid and low-cost than GC-MS. The method can meet the testing requirements of bifenthrin in tea. The efficacy of UPC2 on testing the concentration of bifenthrin in tea was compared with GC-MS based on National Proficiency Testing and the results were satisfactory.

Objective To investigate the correlation between red blood cell distribution width (RDW) and the cardiac function in children with acute heart failure,and to explore the clinical value in evaluating the degree of heart failure.Methods From July 2013 to October 2015,75 cases of children with acute heart failure who were hospitalized in Chengdu Women and Children's Central Hospital were collected and assigned as 3 groups.Heart function classification was done by using a modified Ross scoring system,and each group included 25 cases of class Ⅱ,Ⅲ,Ⅳ.Indices of red blood cell,haemoglobin,RDW,concentration of plasma N-terminal pro brain natriuretic peptide (NT-proBNP),and left ventricular ejection fraction (LVEF) were recorded.SPSS 17.0 software was statistically used for comparing cach index among groups and correlation analysis.Results Red blood cells and haemoglobin were not statistically different among groups (F =0.802,1.372,all P > 0.05).RDW,NT-proBNP concentration and LVEF were significantly different among groups (F =31.388,29.300,x2 =56.952,all P < 0.01),and significantly increased with the progression in the order of class Ⅳ group > class Ⅲ group > class Ⅱ group [RDW:(16.6 ± 1.3) % > (15.4 ± 1.1) % > (13.9-± 1.3) %,NT-proBNP:(506.6 ± 190.2) ng/L > (1 028.1 ± 356.8) ng/L > (1 884.1 ± 358.6) ng/L,all P < 0.01].According to LVEF =50% as the cut-off point,children with acute heart failure were divided into LVEF decreased group and LVEF retention group,former group's RDW and NT-proBNP were significantly higher than the latter group[RDW:(16.7 ± 1.3)% vs.(13.9 ±1.1)%,NT-proBNP:(1 787.4-±368.6) ng/Lvs.(657.4-± 291.1) ng/L,all P <0.01].According to NT-proBNP levels,the children with acute heart failure were divided into low,medium,and high NT-proBNP group,and RDW in the high NT-proBNP group[(17.3 ±0.9)%] was significantly higher than that of medium [(15.4 ± 0.7) %],and that of low level group [(13.7 ± 1.2) %] (all P < 0.01).The correlation analysis between RDW,NT-proBNP as well as LVEF showed that RDW was significantly positive correlated with NT-proBNP (r =O.869,P < 0.01),and negatively related with LVEF (r =-0.962,P < 0.01).Conclusions RDW is closely related to the cardiac function in children with acute heart failure.RDW is increased with the aggravating of acute heart failure,which can indirectly reflect the NT-proBNP concentration and LVEF change and suggests that RDW can be used as a convenient and useful index monitoring the level of cardiac function in children with acute heart failure,and the assessment of the severity of acute heart failure.

Objective:To investigate the relationship of heart rate variability (HRV), heart rate deceleration capacity (DC) and intravenous immunoglobulin (IVIG)-resistant Kawasaki disease (KD) in children with the acute stage of KD.Methods:A total of 679 patients with KD in Chengdu Women and Children′s Central Hospital from August 2015 to May 2019 were selected.In healthy control group, 150 children obtained physical examination at the same time.Prospective cohort study was applied to analyze the data.According to the effect of initial IVIG treatment within 14 days, patients were divided into IVIG-sensitive group and IVIG-resistant group.General clinic information, HRV, DC, blood routine, liver function, cardiac troponin I (cTnI), N-terminal pro-B-type natriuretic peptide (NT-proBNP), high sensitivity C-reactive protein(hs-CRP) and erythrocytesedimentation rate (ESR) before initial IVIG treatment of the 2 groups were compared.Multivariate Logistic regression was applied to analyze the risk factors of IVIG-resistant KD. Results:Among 679 KD patients, 3 cases were lost, among the rest 676 cases, 586 cases were in IVIG-sensitive group, and 90 cases were in IVIG-resistant group.The HRV and DC indexes of IVIG-sensitive group and IVIG-resistant group were lower than those of the healthy control group, and the differences among the 3 groups were statistically significant (all P<0.05). Meanwhile, standard deviation of N-N intervals (SDNN) [(65.84±38.22) ms vs.(82.56±21.41) ms, P=0.004], and low frequency (LF)[ (192.59±114.10) ms 2vs. (258.18±162.75) ms 2, P=0.048] of IVIG-resistant group were lower than those of IVIG-sensitive group.White blood cell (WBC), platelets(PLT), hs-CRP, ESR, alanine aminotransferase(ALT), cTnI and NT proBNP in IVIG sensitive group and IVIG-resistant group were all higher than those in the healthy control group (all P<0.05). Further more, ESR[(90.32±37.91) mm/1 h vs. (65.81±25.34) mm/1 h, P=0.019], cTnI [(0.83±0.35) μg/L vs. (0.52±0.18) μg/L, P=0.037] and NT-proBNP [(854.64±293.02) ng/L vs. (584.95±177.11) ng/L, P=0.011] in IVIG-resistant group were higher than those of IVIG-sensitive group.Multivariate Logistic regression analysis demonstrated that SDNN ( OR=0.783, 95% CI: 0.0341-0.979, P=0.021), and NT-proBNP ( OR=1.195, 95% CI: 1.061-1.428, P=0.34) were independent risk factors for predicting IVIG-resistant KD. Conclusions:SDNN and NT-proBNP may be independent predictors of IVIG-resistant KD.

Objective:To investigate the relationship between the level of Apelin-13 and coronary artery lesion (CAL) in patients with Kawasaki disease (KD), and assess the predictive value of Apelin-13 for CAL in acute phase of KD.Methods:A total of 240 children with KD treated in Chengdu Women and Children′s Central Hospital from September 2017 to October 2019 were recruited, and were divided into KD with CAL (KD-CAL) group and KD without CAL (KD-NCAL) group.Thirty children with acute upper respiratory infection and 30 healthy children were recruited into the febrile control group and the healthy control group, respectively.Blood routine and serum levels of albumin, C-reactive protein (CRP), N-terminal pro-brain natriuretic peptide (NT-proBNP) and Apelin-13 were mea-sured in KD children prior to intravenous gamma globulin injection and after the diagnosis of children in the febrile control group and physical examination of children in the healthy control group.The clinical data of children in each group were compared, and the risk factors of KD complicated with CAL and the predictive value of Apelin-13 were determined by using receiver operating characteristic (ROC) curve and multiple Logistic regression analysis. Results:Apelin-13 and hemoglobin in children with KD were significantly decreased compared with those in the healthy control group and fever control group (all P<0.001). However, white blood cell(WBC) count, platelet count, CRP and NT-proBNP in KD group were significantly increased compared with those in the healthy control group and fever control group (all P<0.001). Serum albumin in KD children was significantly lower than that in the healthy control group ( P=0.004), and there was no difference when compared with the fever control group ( P=0.485). Apelin-13 and hemoglobin were significantly decreased in KD-CAL group compared with KD-NCAL group ( t=10.102, P<0.001; t=2.034, P=0.043), while NT-proBNP and CRP were significantly increased ( t=5.982, 3.728, all P<0.001). Multiple logistic regression analysis showed that Apelin-13 and NT-proBNP were independent predictors of CAL in KD.The ROC curve analysis showed that the cut-off value of Apelin-13 for predicting CAL was 2.99 μg/L, with an area under the curve (AUC) of 0.869 (95% CI: 0.820-0.909), sensitivity of 77.78% and specificity of 88.67%.While NT-proBNP cutoff value of 822 ng/L yielded sensitivity of 57.78% and specificity of 84.62% for predicting CAL with an AUC of 0.718(95% CI: 0.656-0.774). Conclusions:Apelin-13 plays a protective role in KD complicated with CAL, and could be used to predict CAL in the acute phase of KD.

We conducted a prospective study to assess the non-inferiority of adjuvant chemotherapy alone versus adjuvant concurrent chemoradiotherapy (CCRT) as an alternative strategy for patients with early-stage (FIGO 2009 stage IB-IIA) cervical cancer having risk factors after surgery. The condition was assessed in terms of prognosis, adverse effects, and quality of life. This randomized trial involved nine centers across China. Eligible patients were randomized to receive adjuvant chemotherapy or CCRT after surgery. The primary end-point was progression-free survival (PFS). From December 2012 to December 2014, 337 patients were subjected to randomization. Final analysis included 329 patients, including 165 in the adjuvant chemotherapy group and 164 in the adjuvant CCRT group. The median follow-up was 72.1 months. The three-year PFS rates were both 91.9%, and the five-year OS was 90.6% versus 90.0% in adjuvant chemotherapy and CCRT groups, respectively. No significant differences were observed in the PFS or OS between groups. The adjusted HR for PFS was 0.854 (95% confidence interval 0.415-1.757; P = 0.667) favoring adjuvant chemotherapy, excluding the predefined non-inferiority boundary of 1.9. The chemotherapy group showed a tendency toward good quality of life. In comparison with post-operative adjuvant CCRT, adjuvant chemotherapy treatment showed non-inferior efficacy in patients with early-stage cervical cancer having pathological risk factors. Adjuvant chemotherapy alone is a favorable alternative post-operative treatment.

Studies have suggested that the nucleus accumbens (NAc) is implicated in the pathophysiology of major depression; however, the regulatory strategy that targets the NAc to achieve an exclusive and outstanding anti-depression benefit has not been elucidated. Here, we identified a specific reduction of cyclic adenosine monophosphate (cAMP) in the subset of dopamine D1 receptor medium spiny neurons (D1-MSNs) in the NAc that promoted stress susceptibility, while the stimulation of cAMP production in NAc D1-MSNs efficiently rescued depression-like behaviors. Ketamine treatment enhanced cAMP both in D1-MSNs and dopamine D2 receptor medium spiny neurons (D2-MSNs) of depressed mice, however, the rapid antidepressant effect of ketamine solely depended on elevating cAMP in NAc D1-MSNs. We discovered that a higher dose of crocin markedly increased cAMP in the NAc and consistently relieved depression 24 h after oral administration, but not a lower dose. The fast onset property of crocin was verified through multicenter studies. Moreover, crocin specifically targeted at D1-MSN cAMP signaling in the NAc to relieve depression and had no effect on D2-MSN. These findings characterize a new strategy to achieve an exclusive and outstanding anti-depression benefit by elevating cAMP in D1-MSNs in the NAc, and provide a potential rapid antidepressant drug candidate, crocin.
