Objective To compile a comprehension assessment scale of double-conditional phrases for adults and to test its reliability and validity.Methods With reference to the compilation process of local and international word lists,a comprehension assessment scale of double-conditional phrases for adults was developed.The scale was used to assess 40 aphasia patients and 20 ordinary adults as subjects from four hospitals in Shanghai.The internal consistency reliability,split-half reliability,retest reliability and calibration validity of the scale were evaluated and analyzed[the western aphasia battery(WAB)as a calibrated measurcment instrument].Results The scale consists of 30 questions,including five types of phrases:coordinate phrases,verb-object phrases,subject-predicate phrases,endocentric phrases and interface-object phrases.Compared with the ordinary adult group,the total score of the scale and the scores of each dimension in the aphasia group were significantly lower than those in the control group(P＜0.001).The Cronbach's alpha coefficient for the total score was 0.894,the half coefficient was 0.924,and the correlation coefficient for the retest reliability of the total score was 0.923,with retest reliability for each type of word group ranging from 0.731 to 0.903.With the exception of the repetition scores,correlation coefficients be-tween the scale and all other scores of WAB were all＞0.6(P＜0.01).Conclusion The self-developed"Adult Double Conditional Phrases Auditory Comprehension Assessment Scale"demonstrates good reliability and validity.It serves as a scientific and reliable tool for evaluating the auditory comprehension ability of adult patients.

Objective To investigate the effect of the rs3765467 polymorphism of glucagon-like peptide-1 receptor(GLP-1R)gene on the efficacy of Liraglutide(Lir)in patients with type 2 diabetes mellitus(T2DM)and metabolic associated fatty liver disease(MAFLD).Methods A total of 281 patients with T2DM from May 2022 to May 2023 were selected,including 125 patients with simple T2DM(T2DM group)and 156 patients with T2DM combined with MAFLD(T2DM+MAFLD group).120 healthy individuals during the same period were selected as the control(NC)group.The related indexes of glucose and lipid metabolism were detected.The polymorphism of GLP-1R gene rs3765467 was detected.Results BMI,FPG,HbA1c,HOMA-IR and TG in each group increased in turn(P<0.05),while the distribution frequency of genotype GG and allele G decreased in turn(P<0.05).TC and LDL-C in T2DM and T2DM+MAFLD groups were higher than those in NC group(P<0.05).TC and TG levels in genotype GA/AA patients were significantly higher than those in genotype GG patients(P<0.05).Compared with before treatment,the levels of BMI,FPG,HbA1c,HOMA-IR,TC,TG and LDL-C in T2DM patients with MAFLD were significantly decreased after Lir treatment(P<0.05).There was no significant difference in BMI and related indexes of glucose and lipid metabolism in GG and GA/AA patients before and after Lir treatment(P>0.05).Conclusions The distribution frequency of GG and G allele at rs3765467 of GLP-1R gene is reduced in T2DM patients with MAFLD.The carrying of allele A was associated with increased TC and TG levels,but did not affect the efficacy of Lir in reducing weight and improving glycolipid metabolism.

Objective To analyze the factors influencing iodine nutritional status in pregnant women dur-ing pregnancy,based on thyroid function and thyroid autoantibody levels,and to explore the association between iodine nutritional abnormalities and pregnancy outcomes.Methods A total of 838 pregnant women who underwent routine prenatal checkups at Qinghai Provincial People's Hospital between January 2021 and June 2023 were pro-spectively enrolled in this study.All participants were followed until delivery.Seven cases were lost to follow-up,resulting in a final sample size of 831 participants.Among them,276 were in the first trimester,384 in the second trimester,and 171 in the third trimester.Data on urinary iodine concentration(UIC),urinary creatinine(UCr),thyroid function indicators,and thyroid autoantibodies were collected.Based on their iodine nutritional status,the participants were categorized into either the iodine-sufficient group or the iodine-abnormal group(including iodine-deficient,iodine-hyper-sufficient,and iodine-excessive subgroups).This study analyzed the iodine nutritional sta-tus of pregnant women during different gestational periods,compared thyroid function indices,prevalence of thy-roid diseases,and the positivity rates of thyroid peroxidase antibody(TPOAb),thyroglobulin antibody(TGAb),and thyroid-stimulating hormone receptor antibody(TRAb)among different iodine status groups.Additionally,ad-verse pregnancy outcomes were compared across groups.Multivariate logistic regression analysis was conducted to identify risk factors associated with iodine abnormalities during pregnancy,and a predictive model was developed to assess its potential predictive value.Results Among the 831 pregnant women included in the study,373 cases(44.89％)exhibited iodine sufficiency,while 458 cases(55.11％)presented with iodine abnormalities,including 282 cases of iodine deficiency,144 cases of iodine hypersufficiency,and 32 cases of iodine excess.No statistically significant differences were observed in the iodine nutritional status across different trimesters(P>0.05).The se-rum level of thyroid-stimulating hormone(TSH)was significantly higher in the iodine abnormal group compared to the iodine sufficient group(P<0.05).Additionally,the iodine abnormal group demonstrated higher positivity rates of TPOAb alone,TGAb,and TRAb,as well as increased incidence of thyroid dysfunction and total adverse pregnancy outcomes compared to the iodine sufficient group(all P<0.05).These adverse indicators were also sig-nificantly elevated in the iodine-deficient,iodine super-sufficient,and iodine overdose subgroups compared to the iodine sufficient group(P<0.05).Elevated serum TSH levels and the presence of TPOAb,TGAb,and TRAb were identified as risk factors for iodine abnormalities during pregnancy(P<0.05).The predictive model con-structed for identifying iodine abnormalities in pregnant women demonstrated an area under the curve(AUC)of 0.876,with a sensitivity of 72.27％and a specificity of 89.01％.Conclusions The prevalence of iodine nutritional abnormalities among pregnant women during pregnancy was high,with most cases presenting iodine deficiency.These abnormalities were associated with thyroid function,thyroid autoimmunity,and pregnancy outcomes,but showed no significant correlation with gestational age.Furthermore,the prediction model developed based on iden-tified risk factors demonstrated effective performance in predicting iodine nutritional abnormalities during preg-nancy.

Objective To investigate the effect of the rs3765467 polymorphism of glucagon-like peptide-1 receptor(GLP-1R)gene on the efficacy of Liraglutide(Lir)in patients with type 2 diabetes mellitus(T2DM)and metabolic associated fatty liver disease(MAFLD).Methods A total of 281 patients with T2DM from May 2022 to May 2023 were selected,including 125 patients with simple T2DM(T2DM group)and 156 patients with T2DM combined with MAFLD(T2DM+MAFLD group).120 healthy individuals during the same period were selected as the control(NC)group.The related indexes of glucose and lipid metabolism were detected.The polymorphism of GLP-1R gene rs3765467 was detected.Results BMI,FPG,HbA1c,HOMA-IR and TG in each group increased in turn(P<0.05),while the distribution frequency of genotype GG and allele G decreased in turn(P<0.05).TC and LDL-C in T2DM and T2DM+MAFLD groups were higher than those in NC group(P<0.05).TC and TG levels in genotype GA/AA patients were significantly higher than those in genotype GG patients(P<0.05).Compared with before treatment,the levels of BMI,FPG,HbA1c,HOMA-IR,TC,TG and LDL-C in T2DM patients with MAFLD were significantly decreased after Lir treatment(P<0.05).There was no significant difference in BMI and related indexes of glucose and lipid metabolism in GG and GA/AA patients before and after Lir treatment(P>0.05).Conclusions The distribution frequency of GG and G allele at rs3765467 of GLP-1R gene is reduced in T2DM patients with MAFLD.The carrying of allele A was associated with increased TC and TG levels,but did not affect the efficacy of Lir in reducing weight and improving glycolipid metabolism.

Objective To investigate the relationship between polymorphism of resistin(RETN)gene and metabolic associated fatty liver disease(MAFLD)in type 2 diabetes mellitus(T2DM)patients in middle and high altitude areas.Methods A total of 400 patients with T2DM in Qinghai area were recruited and divided into simple T2DM group(T2DM,n=200)and T2DM combined with MAFLD group(T2DM+ MAFLD,n=200)according to liver ultrasonography.Healthy individuals confirmed by physical examination were selected as the normal control group(NC,n=180).Plasma resistin levels were measured by ELISA.The polymorphism of RETN-420C/G and +299G/A genes were detected by PCR sequencing.Results By comparing the polymorphism of RETN-420C/G gene in each group,it was found that the frequencies of G/G genotype and G allele frequency in T2DM+MAFLD group were higher than those in NC group and T2DM group(P<0.05),while the frequencies of C/C genotype and C allele frequency were lower than those in NC group and T2DM group(P<0.05).The risk of MAFLD increased by 1.571,2.126 and 1.537 times respectively in T2DM patients with C/G,G/G genotype and G allele.Logistic regression analysis showed that G/G genotype was a risk factor for MAFLD in T2DM patients.By comparing the polymorphism of RETN+299G/A gene in each group,it was found that A allele frequency in T2DM+MAFLD group was higher than that in NC group and T2DM group,while G allele frequency was lower than that in NC group and T2DM group(P<0.05).The allele A increased the risk of MAFLD in T2DM patients by 1.432 times compared to allele G.Conclusion RETN gene-420C/G locus G/G genotype increases the risk of T2DM combined with MAFLD in middle and high altitudeareas.

Objective:To study the effect of thioredoxin domain containing protein 5 (TXNDC5)-peroxiredoxin 2 (Prx2) on the drug resistance of prostate cancer cells.Methods:Prostate cancer PC3 cells were cultured in vitro, treated with the chemotherapy drug cyclophosphamide (5, 10, 15 μmol/L) for 24 hours, and PC3 cells without any treatment was served as the control group. The expression levels of TXNDC5 in PC3 cells were detected by real-time fluorescent quantitative PCR (RT-qPCR) and Western blotting. PC3 cells with TXNDC5 knocking down were exposed by cyclophosphamide and CCK-8 was used to detect the cell viability of siTXNDC5 group and siNC group. The content of reactive oxygen free radicals was determined by reactive oxygen detection kit. PC3 cells and its parental cyclophosphamide-resistant ones with TXNDC5 knocking down were treated by 10 μmol/L cyclophosphamide and subjected for CCK8 assay. The expression of Prx2 in PC3 cells was detected by Western blotting after TXNDC5 was silenced. Prx2 expression was silenced in PC3 cells overexpressing TXNDC5, and cell viability and reactive oxygen free radical content were detected in Vec-Ctrl group, pcTXNDC5 group, siNC group, siPrx2 group and pcTXNDC5+ siPrx2 group. Results:Compared with the control group, cyclophosphamide treatment significantly increased the expression of TXNDC5 at mRNA and protein levels in PC3 cells. After PC3 cells were treated with cyclophosphamide (10, 15 μmol/L) for 12 h, compared with the siNC group, the cell viability in the siTXNDC5 group was significantly suppressed (0.44±0.08 vs. 0.74±0.10, t=3.647, P=0.031; 0.30±0.04 vs. 0.53±0.06, t=6.115, P=0.006). When PC3 cells were treated with 10 μmol/L cyclophosphamide for 6 and 12 h, compared with the siNC group, the production of reactive oxygen free radicals in the siTXNDC5 group was significantly increased (2.68±0.19 vs. 1.58±0.26, t=-6.027, P=0.005; 4.56±0.37 vs. 2.73±0.26, t=-6.995, P=0.003). When PC3 cells and its cyclophosphamide-resistant ones were treated with 10 μmol/L cyclophosphamide for 12 h, compared with the siNC group, the cell viability was significantly inhibited in the siTXNDC5 group. Western blotting analysis showed that the expression of Prx2 was significantly reduced when TXNDC5 was silenced. Silencing Prx2 could significantly attenuate the increase of cell viability and the decrease of reactive oxygen content resulting from TXNDC5 overexpression. PC3 cells were treated with 10 μmol/L cyclophosphamide for 12 h, and the cell viabilities of the Vec-Ctrl group, pcTXNDC5 group, siNC group, siPrx2 group and pcTXNDC5+ siPrx2 group were 0.52±0.07, 0.69±0.03, 0.56±0.05, 0.43±0.05, 0.58±0.07, respectively, and there was a statistically significant difference ( F=8.868, P=0.003). Furthermore, the cell viability in the pcTXNDC5+ siPrx2 group decreased significantly when compared to that of the pcTXNDC5 group ( P=0.045). The contents of reactive oxygen free radicals in the above 5 groups were 3.26±0.46, 2.09±0.49, 3.16±0.38, 4.62±0.26, 2.87±0.36, respectively, and there was a statistically significant difference ( F=16.037, P<0.001). The content of reactive oxygen radicals in the pcTXNDC5+ siPrx2 group was higher than that of the pcTXNDC5 group ( P=0.036). Conclusion:TXNDC5 can reduce the level of reactive oxygen free radicals in prostate cancer cells by regulating the expression of Prx2, so as to promote the drug resistance of prostate cancer cells.
