Resilience provides mediating effect of resilience between fear of progression and sleep quality in patients with hematological malignancies

BACKGROUND Hematological tumors are common malignant tumors,with high morbidity and mortality rates.Most patients with hematological malignancies develop sleep disorders that seriously affect their life and health because of acute onset of disease,rapid progression,high recurrence rates,complex treatment methods,and treatment costs.AIM To explore the mediating effect of resilience on fear of disease progression and sleep quality in patients with hematological malignancies.METHODS A cross-sectional analysis of 100 patients with hematological malignancies,treated in the First Affiliated Hospital of Jinzhou Medical University between August 2022 and August 2023,was conducted.Patients were assessed using a general data survey,a simplified scale for the fear of progression(FoP)of disease,a resilience scale,and the Pittsburgh Sleep Quality Index.Statistical analysis was conducted to determine the relationship between various patient characteristics and FoP,resilience,and sleep quality.Spearman’s correlation analysis was used to examine the correlations between mental resilience,FoP,and sleep quality.RESULTS The total FoP score mean value in patients with hematological malignancies was 38.09±5.16;the total resilience score mean value was 40.73±7.04;and the Pittsburgh Sleep Quality Index score mean value was 10.72±1.90.FoP,resilience,and sleep quality of the patients were associated with family per capita monthly income and patient education level(P<0.05).Spearman correlation analysis revealed that FoP was negatively correlated with resilience and sleep quality scores(r=-0.560,-0.537,P<0.01),respectively,and resilience was significantly associated with sleep quality scores(r=0.688,P<0.01).Mediation analysis showed that the mediating effect of resilience between FoP and sleep quality in patients with hematological malignancies was-0.100 and accounted for 50.51%of the total effect.This indicated that FoP directly and indirectly affected sleep quality through the mesomeric effect of resilience.CONCLUSION Resilience is an intermediary variable between FoP and sleep quality in patients with hematological malignancies.Medical staff should evaluate and follow-up FoP and resilience to implement measures to improve sleep quality.

前囊抛光对白内障术后视觉质量的影响

目的:评价前囊抛光对白内障超声乳化术后视觉质量的影响。方法:前瞻性随机对照研究。纳入2021-11/2022-06于应急总医院眼科行白内障超声乳化联合人工晶状体(IOL)植入术的年龄相关性白内障患者65例73眼,随机分为抛光组(30例35眼,术中行前后囊联合抛光)和对照组(35例38眼,术中仅行后囊抛光)。观察术后1wk,1、3、6mo最佳矫正视力,术后3、6mo测量前囊口面积,并使用Pentacam三维眼前节系统评估后囊膜混浊程度(P评分)、IOL倾斜度和偏心量,使用OPD-ScanⅢ光程差分析系统评估波前像差、点扩散函数(PSF)的斯特列尔比(SR)和调制传递函数(MTF)。结果:术后1wk,1、3、6mo,抛光组患者最佳矫正视力均优于对照组(P<0.05)。术后3、6mo,两组患者前囊口面积、后囊膜混浊程度(P评分)、IOL偏心量、PSF的SR值和MTF均无差异(P>0.05)。术后3mo,两组患者IOL倾斜度、波前像差均无差异(P>0.05),但术后6mo,抛光组IOL倾斜度小于对照组[(1.65±0.60)°vs(2.34±0.43)°,P<0.001)],波前像差也小于对照组(0.03±0.01μm vs 0.06±0.03μm,P<0.001)。结论:白内障超声乳化吸除术中行360°抛光前后囊膜能提高术后最佳矫正视力,且术后IOL倾斜度更低、波前像差更小,视觉质量更好。

Analysis of Phytochemical Constituents of Zuogui Wan in Rat Serum and its Effects on Early Embryonic Development of Mice

Objective:Zuogui Wan(ZGW)has been used as a typical prescription for tonifying kidney essence in traditional Chinese medicine.The objective of this study is to elucidate the phytochemical constituents of ZGW-treated rat serum(ZGWRS)using ultra-performance liquid chromatography-electrospray ionization/quadrupole-time-of-flight high-definition mass spectrometry(UPLC-ESI-Q-TOF-MS).Methods:ZGW was administered to rats,and the phytochemical constituents in rat serum were determined using UPLC-ESI-Q-TOF-MS.MetaboLynx analysis in negative ion mode was adopted to characterize the chemical constituents of ZGWRS.Orthogonal partial least squares discriminant analysis was applied for the discovery of constituents of ZGW that entered the serum of rats.The fertilized eggs collected from the same experiment were randomly divided into four groups,including the normal,40 mmol/L glucose,40 mmol/L glucose 5%control rat serum,and 40 mmol/L glucose 5%ZGWRS groups.They were cultivated at 37°C and 5%CO2 in a saturated humidity CO2 incubator.The blastocyst rate and two-cell rate were used to evaluate the effects of ZGWRS on embryonic development.Results:Thirteen constituents were identified in the ZGWRS,among which sweroside,loganin,morroniside,loganic acid,and 8-epiloganic acid were from Fructus Corni(Shan Zhu Yu).5-Hydroxymethyl-2-furfural-glucuronide,2-H-5-hydroxymethyl-2-furfural-glucuronide,3-hydroxy-2,6,6-trimethyl-1-cyclohexene-1-carboxylic acid,andβ-D-ribofuranuronic acid methyl ester triacetate were from Radix Rehmanniae Preparata(Shu Di Huang).Coumaric acid was from Fructus Lycii(Gou Qi Zi).Kaempferol-3-beta-O-glucuronide and cuscutamine were from Semen Cuscutae(Tu Si Zi).The embryonic development was significantly inhibited using 40 mmol/L glucose.Compared with the normal group,the blastocyst rate of the glucose group was decreased.The blastocyst rate of the 40 mmol/L glucose 5%ZGWRS group was significantly higher than that of the glucose group,indicating that ZGWRS negates the effect of glucose on mouse embryonic development.Conclusion:The results verified that a rapid and robust UPLC-ESI-Q-TOF-MS-based platform had been successful for identifying multiple constituents of ZGW.ZGWRS is rich in active constituents of iridoid glycosides.The results of this study also showed that ZGWRS could negate the effect of glucose on mouse embryonic development.

Effects of Sijunzi Dripping Pill on Gastrointestinal Motility of Mice

Objective To study the effects of Sijunzi Dripping Pill（SDP）on gastrointestinal motilityof mice.Methods The diarrhea and swimming model of mice was made by Rhei Radixet Rhizoma-induced spleen deficiency.The intestinal transit,gastric emptying test,serum motilin（MTL）,vasoactive intestinal peptide（VIP）,and substance P（SP）were chosen to observe the effects of high-,mid-,and low-dose SDP on stomach movements,and the water extractive of Sijunzi Decoction was used as positive control.Results Compared with the control group,the gastric emptying rate in the gastrointestinal motility group was significantly decreased,the intestinal propulsion rate was obviously increased,the levels of MTL,prostaglandin E2（PGE2）,and SP were increased（P〈0.05）,while the level of VIP was decreased（P〈0.05）.Compared with the model group,SDP could decrease the intestinal transit rate,whereas increase the gastric emptying rate and the level of MTL（P〈0.05）;The high-dose SDP could decrease the level of PGE2（P〈0.05）and the low-dose SDP could decrease the level of VIP（P〈0.05）;Each group had no significant effect on SP.Conclusion SDP has the good effect on increasing the gastrointestinal motility of mice,and its function may partly relate to the regulation of the levels of MTL and VIP as well as PGE2.

Ethnopharmacological Investigation and Rapid Authentication of Mongolian Patent Medicines Digeda

Objective To investigate Mongolian medicinal plants called Digeda and the prescriptions in Inner Mongolia region and to establish a molecular method for authentication of Digeda Mongolian patent medicines （MPMs）. Methods A field investigation was conducted on traditional uses of Digeda. After interviewed traditional healers in Mongolian, ethnopharmacological information of Digeda prescriptions was recorded in detail, including names, compositions, and traditional uses. And the total DNA from 10 MPMs has been amplified by three pairs of specific primers. Specific PCR products were further identified by sequence alignment with the known sequences already submitted in GenBank or own sequences. Results Fifteen Digeda plants and 29 Digeda prescriptions with their ethnopharmacological knowledge were collected. Ten MPM samples containing Lomatogonium rotatum, Viola philippica, and Corydalis bungeana were successfully evidenced by PCR with specific bands as raw materials. Conclusion Digeda should be further investigated in ethnopharmacology, which is a fundamental step toward developing efficacious natural drugs for various diseases. PCR amplification of specific allele is an easy and economical method, which can be used to identify highly processed MPMs and will assist in monitoring their qualities and legalities.
