OBJECTIVE: To compare the prevalence of chromosomal aneuploidies and pregnancy outcomes of D5 and D6 blastocysts subjected to preimplantation genetic testing for aneuploidy (PGT-A). METHODS: Clinical and laboratory data of 268 couples who underwent PGT-A at the Reproductive Center of the First Affiliated Hospital of Zhengzhou University from September 2018 to September 2020 were collected. The prevalence of chromosomal aneuploidies and pregnancy outcomes of D5/D6 biopsied blastocysts were compared. RESULTS: Compared with D6 blastocysts, the euploidy rate of D5 blastocysts was significantly higher (49.1% vs. 41.1%, P = 0.001 1), whilst their aneuploidy rate was significantly lower (50.9% vs. 58.9%, P = 0.001 1). The rate of numerical abnormalities of D6 blastocysts was significantly higher than that of D5 blastocysts (27.9% vs. 20.2%, P = 0.000 5). For patients under 35 years old, the euploidy rate of D5 blastocysts was significantly higher than that of D6 blastocysts (53.8% vs. 44.3%, P = 0.001), whilst the numerical abnormality rate was significantly lower (16.3% vs. 23.9%, P = 0.001). For both D5 and D6 blastocysts, the euploidy rates for patients <= 35 were significantly higher than those for > 35. The elder group had the lowest rates for aneuploidies and live births. Compared with those receiving D6 blastocysts transplantation, the pregnancy rate, implantation rate and live birth rate for those receiving thawed D5 blastocysts transplantation were significantly higher (60.2% vs.37.0%, P = 0.000 3; 59.1% vs.37.0%, P = 0.000 6; 47.7% vs. 28.3%, P = 0.002). CONCLUSION For patients undergoing PGT-A, the chromosomal euploidy rate for D5 blastocysts is higher than that for D6 blastocysts, and the clinical outcome of D5 blastocysts with normal signal is better than that of D6 blastocysts. Elder patients have a higher rate of aneuploidies.

Objective:This paper is to evaluate the curative effect of Self-made Jishen prescription combined with conventional western medicine in the treatment of type 2 diabetic kidney disease (DKD) with both deficiency of both qi and yin and blood stasis.Methods:A total of 80 patients from February 2019 to July 2020 with the syndrome of deficiency of both Qi and Yin with blood stasis in the DKD Ⅲ stage of Ruzhou Jiren Diabetes Hospital were selected. Those patients who met the diagnostic criteria were randomly divided into 2 groups, the control group and the treatment group, according to registration orders, with 40 in each group. The control group was treated with conventional western medicine therapy, and the treatment group was treated with modified self-made Jishen prescription on the basis of the control group. The treatment of both groups lasted for 3 months. Traditional Chinese Medicine (TCM) symptoms were scored before and after the treatment; hexokinase method was used to detect FPG, sarcosine oxidase method was used to detect SCr and eGFR were calculated, latex enhanced turbidimetric inhibition immuno assay method was used to detect hypersensitive C-reactive protein (hs-CRP), the sandwich ELISA was used to detect transforming growth factor-β1 (TGF-β1), and HbA1c was detected by high performance liquid chromatography; 24 h urine was collected, and 24 hUTP was detected by pyrogallol red-molybdenum method; and the clinical efficacy was evaluated.Results:The total effective rate was 87.5% (35/40) in the treatment group and 67.5% (27/40) in the control group. The difference between the two groups was statistically significant ( Z=-2.72, P=0.006). After treatment, hs-CRP [(2.52±1.02) mg/L vs. (3.21±1.22) mg/L, t=2.74], TGF-β1 [(32.2±6.52) mg/L vs. (38.3±6.8) mg/L, t=-4.97], 24 hUTP [(120.91±38.84) mg vs. (144.84 ±49.69) mg, t=-5.94] in the treatment group were significantly lower than those in the control group ( P<0.05); eGFR [(66.23±4.91)ml?min -1?1.73m -2vs. (59.69 ±4.51) ml?min -1?1.73m -2, t=6.61] in the treatment group was significantly higher than that of the control group ( P<0.05). The TCM Symptom Score after treatment in the treatment group was significantly lower than that of the control group ( P<0.01). Conclusion:For the patients with T2DM kidney disease of Phase Ⅲ with Deficiency of both Qi and Yin and Blood Stasis, the treatment of self-made Jishen prescription combined with conventional western medicine can inhibit the inflammatory reaction and renal interstitial fibrosis, improve the glomerular filtration rate, and reduce the excretion of urine protein.

Purpose: Drug resistance is one of the main causes of chemotherapy failure in patients with small cell lung cancer (SCLC), and extensive biological studies into chemotherapy drug resistance are required. Materials and Methods: In this study, we performed lncRNA microarray, in vitro functional assays, in vivo models and cDNA microarray to evaluate the impact of lncRNA in SCLC chemoresistance. Results: The results showed that KCNQ1OT1 expression was upregulated in SCLC tissues and was a poor prognostic factor for patients with SCLC. Knockdown of KCNQ1OT1 inhibited cell proliferation, migration, chemoresistance and promoted apoptosis of SCLC cells. Mechanistic investigation showed that KCNQ1OT1 can activate transforming growth factor-β1 mediated epithelial-to-mesenchymal transition in SCLC cells. Conclusion Taken together, our study revealed the role of KCNQ1OT1 in the progression and chemoresistance of SCLC, and suggested KCNQ1OT1 as a potential diagnostic and prognostic biomarker in SCLC clinical management.

Objective To analyze the influence of Eomecon chionanthe alkaloids(ECA)on differential expression of liver proteins from Oncomlania hupensis.Methods O.hupensis was immersed in 10 mg/L ECA or clean water for 36 h and livers were isolated from live snails.Total liver proteins were extracted and separated by two-dimensional gel electrophoresis,differentially expressed proteins between ECA group and clean water group were selected and analyzed by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry(MALDI-TOF-MS)and tandem mass spectrometry sequencing of tryptic peptides.Results There were(354?110)and(311?12)spots observed in ECA group and in water group,respectively.Eleven differential expressed proteins were identified and all were up-regulated in ECA group.The eleven identified proteins were hypothetical protein,ENSANGP00000022175,class I aldehyde dehydrogenase,unknown protein,ENSANGP00000027067,protein similar to ankyrin 3 isoform 1 isoform 4,protein similar to hepatitis A virus cellular receptor 1 short form,mitochondrial isocitrate dehydrogenase 2-like,protein similar to keratin,keratin-10,and keratin-1,respectively.Conclusion Expression of liver proteins from O.hupensis could be changed when immerse in ECA.

Objective To investigate the relationship between the calcium ion and the effects of ECA on the contraction of the smooth muscles of Oncomelania foot, and explore the mechanism of ECA in decreasing the snail climbing adhesion and increasing snail-killing. Method The in vitro experiment was used to observe the effects of ECA on contraction activities of foot smooth muscles of Oncomelania. Results ECA 5. 0, 10. 0, 20. 0 mg/L. enhanced the resting tension, decreased the contraction range and increased the contraction frequency of the foot smooth muscles of Oncomelania in Ringer's solution with or without Ca2+ , with a characteristic of the dose-dependent, but stronger in solution with Ca2+ than that in solution without Ca2+. Conclusions ECA can enhance the resting tension, decrease the contraction range and increase the contraction frequency of the foot smooth muscles of Oncomelania. This suggested that ECA could be related to increasing the intracellular Ca2+ release and influx of the extracellular Ca2+. This could provide an explanation why ECA decreases the rate of Oncomelania climbing adhesion and enhances snail-killing.
