ABSTRACT

ObjectiveTo explore the anti-abortional effect of Pangshi Antai Zhixue decoction and its mechanism in helper T lymphocyte 1 (Th1)/Th2 balance in the decidual tissues of spontaneous abortion rats with heat syndrome, based on the p38 mitogen-activated protein kinase (p38 MAPK) signaling pathway. MethodAconiti Lateralis Radix Praeparata, Zingiberis Rhizoma, and Cinnamomi Cortex decoction was used to replicate the rat model of spontaneous abortion with heat syndrome. The spontaneous abortion rats with heat syndrome were randomly divided into model group, aspirin group (5.25 mg·kg-1), dydrogesterone group (3.02 mg·kg-1), Pangshi Antai Zhixue decoction high-dose (44 g·kg-1), medium-dose (22 g·kg-1), and low-dose (11 g·kg-1) groups, with ten rats in each group. Ten normal rats were divided into a normal group. Rats in each group were given corresponding drugs, Once a day for 12 d. After 24 h of the last administration, blood was collected from the abdominal aorta. The enzyme-linked immunosorbent assay (ELISA) was used to determine the levels of β-human chorionic gonadotropin (β-HCG), progesterone (P), estradiol (E2), γ interferon (IFN-γ), and interleukin-4 (IL-4) in rat serum. The uterus and meconium tissues of rats were collected to determine the number and rate of miscarriages. Western blot was used to detect GATA3, T-bet, p38 MAPK, and its phosphorylation in the decidual tissue. ResultAs compared with the normal group, the number of live births, the β-HCG, P, E2, and IL-4 in the serum, and the GATA3 protein expression in the decidual tissue in the model group were reduced (P<0.01), whereas the number and rate of miscarriages, IFN-γ in the serum, and the expression of p-p38 MAPK and T-bet protein levels in the demolded tissues increased (P<0.01). As compared with the model group, the number of live births, the β-HCG, P, E2, and IL-4 in the serum, and the GATA3 protein expression in the decidual tissue in the Pangshi Antai Zhixue decoction medium-dose group increased (P<0.01), whereas the number and rate of miscarriages, IFN-γ in the serum, and the expression of p-p38 and T-bet protein levels in the demolded tissues reduced (P<0.01). As compared with the aspirin group, the P, E2, and IL-4 in the serum of rats in the dydrogesterone group and the Pangshi Antai Zhixue decoction high-dose and medium-dose groups increased (P<0.01), the number of live births in the Pangshi Antai Zhixue decoction medium-dose group increased (P<0.01), and the β-HCG and IFN-γ in the serum of rats in the dydrogesterone group decreased (P<0.01). The number and rate of miscarriages, IFN-γ in the serum, and T-bet and GATA3 levels in the decidual tissues of rats in the Pangshi Antai Zhixue decoction medium-dose group decreased (P<0.05). Compared with the Pangshi Antai Zhixue decoction medium-dose group, the low-dose group, high-dose group, and dydrogesterone group showed increased number and rate of miscarriages (P<0.05), and the high-dose group and dydrogesterone group decreased the number of live birth (P<0.01). The IFN-γ in the serum and p-p38 MAPK and T-bet protein in the decidual tissue in the low-dose group, and the p-p38 MAPK and T-bet protein in the decidual tissue in the high-dose group all increased (P<0.05). The β-HCG, P, and E2 in the serum of rats in the Pangshi Antai Zhixue decoction low-dose group, dydrogesterone group, and aspirin group decreased (P<0.01), and the IL-4 in the serum and GATA3 in the decidual tissue of rats in the Pangshi Antai Zhixue decoction low-dose and high-dose group and the dydrogesterone group decreased (P<0.01). ConclusionPangshi Antai Zhixue decoction realizes the effect of fetal protection by regulating the activation of p38 MAPK signal pathways and Th1/Th2 balance.

ABSTRACT

Objective:To compare the differences in population distribution and prognosis of patients with nasopharyngeal carcinoma (NPC) treated with intensity-modulated radiotherapy (IMRT) in T staging of the Union for International Cancer Control (UICC) 7th edition and UICC 8th edition, and to analyze the prognostic factors in patients with NPC.Methods:The clinicopathologic date of 184 patients with newly diagnosed NPC treated with IMRT at the Department of Radiation Oncology of Weifang People′s Hospital of Shandong Province from June 1, 2005 to December 31, 2017 were retrospectively analyzed. All patients were restaged according to the 7th and 8th edition of the UICC staging system. The distribution of T staging of patients in the two staging systems was analyzed, and the consistency of the two staging systems was compared using the Kappa consistency test. Kaplan-Meier method was used for survival analysis, and log-rank test was used to compare the prognostic differences among T stages. Cox regression model was used to analyze the prognostic factors of patients with NPC.Results:Of all 184 patients with NPC, stage T 1, T 2, T 3 and T 4 respectively accounted for 18.5% (34/184), 16.8% (31/184), 15.2% (28/184) and 49.5% (91/184) according to the 7th edition UICC staging system. However, stage T 1, T 2, T 3 and T 4 respectively accounted for 18.5% (34/184), 34.2% (63/184), 30.4% (56/184) and 16.8% (31/184) according to the 8th edition UICC staging system. The T staging population distribution of the two staging systems showed moderate consistency (Kappa=0.58). There was a statistically significant difference in overall survival (OS) among patients with stage T 1, T 2, T 3, T 4 according to the 7th edition UICC staging system ( χ2=10.606, P=0.014). There were statistically significant differences in OS between stage T 1 and stage T 2, T 3, T 4 ( χ2=4.866, P=0.027; χ2=11.965, P=0.001; χ2=4.351, P=0.037). The OS curves of stage T 2 and T 4 could not be separated. Moreover, the OS curves of stage T 3 and T 4 were distributed in reverse order. There was a statistically significant difference in OS among patients with stage T 1, T 2, T 3, T 4 according to the 8th edition staging system ( χ2=8.663, P=0.034). There were statistically significant differences in OS between stage T 1 and stage T 3, T 4( χ2=8.746, P=0.003; χ2=7.580, P=0.006). The OS curves of stage T 1 to T 4 were distributed in order, but the curves of stage T 3 and T 4 could not be separated. There was a statistically significant difference in progression-free survival (PFS) among patients with stage T 1, T 2, T 3, T 4 according to the 7th edition UICC staging system ( χ2=11.289, P=0.010). There were statistically significant differences in PFS between stage T 1 and stage T 2, T 3, T 4 ( χ2=8.209, P=0.004; χ2=13.302, P<0.001; χ2=6.550, P=0.010). The PFS curves of stage T 2 and T 4 could not be separated. Moreover, the PFS curves of stage T 3 and T 4 were distributed in reverse order. There was a statistically significant difference in PFS among patients with stage T 1, T 2, T 3, T 4 according to the 8th edition staging system ( χ2=12.074, P=0.007). There were statistically significant differences in PFS between stage T 1 and stage T 2, T 3, T 4( χ2=5.182, P=0.023; χ2=11.217, P=0.001; χ2=10.174, P=0.001). The PFS curves of stage T 1 to T 4 were distributed in order, but the curves of stage T 3 and T 4 could not be separated. The results of Cox multivariate analysis showed that T staging of both staging systems were the independent prognostic factors of the OS ( P=0.013; P=0.026) and PFS ( P=0.031; P=0.012). However, T staging of the two editions were not the independent prognostic factors of the local recurrence-free survival (LRFS) ( P=0.351; P=0.167) and distant metastasis-free survival (DMFS) ( P=0.059; P=0.052). The age was the independent prognostic factor of the OS ( HR=2.70, 95% CI: 1.53-4.76, P=0.001; HR=2.74, 95% CI: 1.55-4.84, P=0.001), PFS ( HR=2.72, 95% CI: 1.46-5.08, P=0.002; HR=2.94, 95% CI: 1.57-5.52, P=0.001), LRFS ( HR=5.87, 95% CI: 1.62-21.27, P=0.007; HR=6.02, 95% CI: 1.61-22.49, P=0.008) and DMFS ( HR=2.40, 95% CI: 1.22-4.72, P=0.011; HR=2.63, 95% CI: 1.34-5.18, P=0.005). N staging was the independent prognostic factor of the OS ( P=0.031; P=0.028). Conclusion:The T staging population distribution of the 7th and 8th edition UICC staging system had moderate consistency, and the T staging of the 8th edition is more advantageous in predicting the prognosis of OS and PFS. In both editions, T staging is an independent prognostic factor for OS and PFS.

ABSTRACT

Objective @#To understand the spatial distribution of iodine in drinking water in Wenzhou,and to provide reference for preventing iodine deficiency disorders.@*Methods @#Drinking water was sampled from 182 townships of all 11 counties under the jurisdiction of Wenzhou according to different ways of water supply. The iodine in water was detected by cerium sulfate catalytic spectrophotometry. The water iodine data was matched with the electronic map by ArcGIS10.2 to construct a spatial database; spatial autocorrelation analysis by GeoDa1.10 and spatial scanning analysis by SaTScan 9.4 were conducted to obtain the water iodine concentration range in Wenzhou. @*Results @#The contents of iodine in 998 out of 1 008 drinking water samples were less than 10 μg/L,accounting for 99.01%. The median of water iodine in all townships of Wenzhou was 1.8 μg/L. The results of geospatial distribution analysis demonstrated that the iodine distribution in drinking water had positive spatial autocorrelation in Wenzhou(Moran's I= 0.40,Z=15.65,P< 0.05); there were four kinds of local aggregation models for water iodine in 78 townships(P< 0.01). Three cluster areas of the water iodine were detected by space scanning,with three townships in Dongtou as the first high cluster areas,seven coastal townships in Cangnan as the second high cluster areas and 49 mountainous townships in Yongjia,Yueqing and Lucheng as the low cluster areas.@*Conclusion @#The iodine in drinking water in Wenzhou was low and exists spatial aggregation.

ABSTRACT

Objective To understand the dynamic conditions after reaching the stage goal of elimination of iodine deficiency disorders (IDD) in Wenzhou, and to provide a scientific basis for prevention and treatment of IDD. Methods Three counties that the annual consumption rate of qualified iodized salt < 80% in 2014 and had the prevalence of endemic cretinism in history, Cangnan, Taishun and Yongjia, were selected as high risk monitoring areas. Three townships were selected in each area, and two primary schools were selected from each township, and 40 children urine samples were collected in each school (half male and half female) and the age of children were 8-10 years old. And near the location of these primary schools, we randomly selected 10 pregnant women in each village, and estimated the urinary iodine level and salt iodine concentration, respectively. The examination of thyroid by B ultrasound was performed in children by provincial professionals. Urinary iodine was determined using the arsenic cerium catalytic spectrophotometric method (GB/T 13025.7-2012). Salt iodine was determined by direct titration. Results Endemic cretinism case was not found in this survey, total goiter rate of 8-10 years old children was 2.04%(16/783). The median of urinary iodine was 116.1 and 108.2 μg/L, respectively, in 8 - 10 years old children and pregnant women. Iodized salt coverage rate was 90.48%(171/189), the intaking rate of qualified iodized salt was 84.66% (160/189). The concentration of pregnant women urinary iodine and salt iodine was positively correlated (r=0.54, P< 0.05). Conclusions Children's iodine nutrition is in the appropriate level, but pregnant women are in iodine definciency in Wenzhou City.

ABSTRACT

Due to its great clinical significance, brain injury following cardiac arrest (CA) has attracted more attention now. Meanwhile, there are currently no approved real time objective methods used to monitor brain injury following CA. In this study, we adopt the method of nonextensive Kullback-Leibler Entropy in investigating the HRV signals from brain injury and compare the result with that of corresponding EEG analysis. The comparative analysis shows that Kullback-Leibler Entropy can reveal the injury level of brain following CA. And we propose a novel quantitative approach for monitoring brain injury.
