Objective:To evaluate the efficacy and safety of luspatercept combined with roxadustat in patients with refractory low-risk myelodysplastic neoplasms with ring sideroblasts (MDS-RS) patients.Methods:In this single-center, prospective, randomized controlled trial, patients with refractory MDS-RS were randomly assigned in a 1:2 ratio to receive either combination therapy (luspatercept + roxadustat) or luspatercept monotherapy. The primary endpoint was erythroid response at 12 weeks, while secondary endpoints included erythroid response at 24 weeks, achievement of transfusion independence ≥8 weeks within the first 12 weeks, and other hematologic indicators.Results:The combination therapy and monotherapy groups included 16 and 32 patients, respectively. Baseline demographic characteristics, laboratory tests, IPSS-R risk classification, transfusion burden, EPO levels, and previous treatment history were comparable between the two groups ( P>0.05). With similar doses of luspatercept and follow-up durations, no significant differences were observed between the groups at either 12 or 24 weeks in terms of erythroid response, transfusion independence, or other clinical indicators (all P-values>0.05). The incidence of adverse events was similar in both groups (all P-values>0.05) . Conclusion:Luspatercept combined with roxadustat shows comparable efficacy and safety to luspatercept monotherapy in the treatment of refractory low-risk MDS-RS.

Objective:To explore the effects of anshen jieyu decoction on hippocampal morphology and regulation of PI3K/AKT signalling pathway with hypothalamic-pituitary-adrenal axis expression in CUMS depressed rats.Methods:Rats were divided into a control group(Control),CUMS model group(CUMS),and ASJYD treatment group(CUMS+ASJYD).Rats in the CUMS and CUMS+ASJYD groups were exposed to 10 different chronic stressors to induce depressive-like behaviors.After modeling,the CUMS+ASJYD group received ASJYD via gavage.Depressive-like behaviors were assessed using the sucrose preference test and open field test.Serum levels of adrenocorticotropic hor-mone(ACTH)and corticosterone(CORT)were measured by ELISA.Hippocampal neuronal morphological changes were observed via Nissl staining,mitochondrial ultrastructure was examined using transmission electron microscopy,and hippocampal PI3K and AKT protein phosphorylation levels were detected by Western blot.Results:Compared with the Control group,the CUMS group showed significantly reduced sucrose consumption,preference rate,total travel distance in the open field,and central zone activity time(P＜0.01).Serum ACTH and CORT levels were elevated(P＜0.01),with disorganized hippocampal cell arrangement,reduced cell count,mitochondrial swelling,cristae blurring/rupture observed under electron microscopy,and decreased phosphorylation levels of PI3 K and AKT proteins(P＜0.01).After ASJYD treatment,the CUMS+ASJYD group exhibited significant improvements in sucrose consumption,preference rate,locomotor activity,and central zone exploration(P＜0.01),accompanied by reduced ACTH/CORT expression,alleviated hippocampal pathology,restored mitochondrial integrity with clear cristae,and increased PI3K/AKT phosphorylation(P＜0.01).Conclusion:Anshen Jieyu decoction significantly improved the depression-like be-haviour of CUMS rats,which may be achieved by down-regulating the hyperactive hypothalamic-pituitary-adrenal axis,regulating the expression of PI3K/AKT signaling pathway,and ameliorating the damage to hippocampal neurons and mi-tochondria.

Objective:To study the predictive values of umbilical artery blood gas analysis(UABG) plus amplitude-integrated electroencephalography(aEEG) monitoring within 6 h after birth for early complications and short term neurological outcomes in low Apgar score neonates.Methods:From January 2020 to February 2022, neonates with gestational age (GA) ≥35 weeks and 1 min or 5 min Apgar score ≤7 admitted to NICU of our hospital were retrospectively reviewed. According to UABG pH values, the neonates were assigned into pH<7.2 group and pH ≥7.2 group, and further grouped into abnormal aEEG group and normal aEEG group. The ttest, rank sum test and χ2 test were used to compare laboratory results, incidences of diseases, physical growth and neurological prognosis at 6 month of age. Results:A total of 105 neonates with low Apgar scores were enrolled, including 73 cases in the pH<7.2 group and 32 cases in the pH≥7.2 group. In the pH<7.2 group, 52(71.2%) had abnormal aEEG and 21 had normal aEEG. In the pH≥7.2 group, 6(18.8%) had abnormal aEEG and 26 had normal aEEG. The incidence of abnormal aEEG in the pH<7.2 group was higher than the pH≥7.2 group ( P<0.001). The degree of aEEG abnormality was negatively correlated with UABG pH ( r=-0.463, P<0.001). In the pH<7.2 group, the levels of creatine kinase isozymes (CK-MB), activated partial thromboplastin time and the incidence of hypoxic-ischemic encephalopathy (HIE) in neonates with abnormal aEEG were significantly higher than those with normal aEEG, and the head circumference (HC) at 6 month was significantly smaller in neonates with abnormal aEEG (all P<0.05). In the pH≥7.2 group, the level of CK-MB, incidences of HIE and respiratory failure in neonates with abnormal aEEG were higher than those with normal aEEG, HC at 6 month was smaller and the incidence of adverse neurological prognosis was higher in neonates with abnormal aEEG (all P<0.05). Conclusions:UABG plus aEEG monitoring within 6 h after birth shows predictive values for early complications and short term neurological outcomes in low Apgar scores neonates.

Objective:To evaluate the application of multiparametric MRI (mpMRI)-transrectal ultrasound (TRUS) fusion guided biopsy in the diagnosis of clinical significant prostate cancer (PCa).Methods:A prospective analysis was performed in 168 patients with suspected PCa from September 2015 to June 2017 in the First Affiliated Hospital of Soochow University. Suspicious areas on mpMRl were defined and graded using prostate imaging reporting and data system version 2 (PI-RADS V2) score. All the patients had the TRUS-guided systematic biopsy, 108 patients with PI-RAD V2 scores ≥ 3 had additional MRI-TRUS targeted biopsies. Taking pathologic results as golden standard, the detection rates were compared between the 2 methods using χ 2 test. Results:Initially, all of the 168 patients underwent TRUS biopsy. PCa was detected in 86 (101 niduses) of 168 patients (51.19%, 86/168), 82 (91 niduses) (48.81%, 82/168) were not prostate cancer. Seventy eight (46.43%, 78/168) cases of PCa were detected by TRUS biopsy, and 63 (58.33%, 63/168) cases of PCa were detected by MRI-TRUS fusion guided biopsy, the difference was statistically significant between TRUS biopsy and MRI-TRUS fusion guided biopsy (χ 2=3.73, P=0.035). The 168 patients were biopsied with a total of 2 300 cores, including TRUS biopsy 2 016 cores and MRI-TRUS fusion targeted biopsy 284 cores. Additionally, the detection rate for per cores for MRI-TRUS fusion targeted biopsy (51.76%, 147/284) was significantly higher than that for TRUS biopsy cores (19.64%, 396/2 016) (χ 2=142.38, P<0.05). Among patients with a positive biopsy for PCa, the biopsy cores for conventional TRUS biopsy was 1 032 comparing to 214 cores for MRI-TRUS biopsy. The suspicious MRI-TRUS fusion targeted biopsy (68.69%, 147/214) detected more PCa compared with TRUS biopsy (38.37%, 396/1 032) (χ 2=66.27, P<0.05). Among patients with a positive biopsy for PCa, MRI-TRUS fusion targeted biopsy [69.74% (106/152)] detected more significant cancer cores than TRUS biopsy [54.50% (351/644) ] (χ 2=11.67, P<0.05). Conclusion:MRI-TRUS fusion biopsy combined with PI-RADS V2 increases positive rate markedly and improves the detection rate of clinical significant PCa.

Objective To evaluate the diagnostic value of intravoxel incoherent motion (IVIM) and diffusion kurtosis imaging (DKI) parameters in diagnosing prostate cancer(PCa) in transition zone (TZ) and stratifying pathologic Gleason grade of prostate cancer. Methods A total of 55 patients who were undergoing preoperative muti?parameters MRI of T2WI, DWI, IVIM and DKI model for the exploration of prostate cancer (January 2015 to June 2017) with pathologically confirmed by MRI?transrectal ultrasound (TRUS) targeted fusion biopsy were retrospectively included. Parameters were postprocessed by IVIM models including quantitation of perfusion fraction (f), diffusivity (D) and pseudo?diffusivity (D*) and DKI models including the mean diffusivity (MD), mean kurtosis (MK) and fractional anisotropy (FA) by outlining the 3D VOI. Independent sample t?test was used to compare the differences in lesion parameters between prostate cancer and BPH, low?risk (BPH+Gleason score 6 points) and medium?high?risk lesions (Gleason score ≥7 points). Correlation between ADC values, IVIM and DKI parameters and Gleason scores were assessed with Spearman analysis.Receiver operating characteristic curve analysis was used to evaluate the efficacy of various parameters in the differential diagnosis of prostate cancer and BPH with low?risk or high?risk. Results 27 (36 focus) cases of PCa and 28 (40 focus) cases of benign prostatic hyperplasia(BPH) in PZ were included, meanwhile, the cases of GS≥7 and and BPH+(GS=6) were 33,43,respectively. There were significant differences in ADC, D, MD, MK, and FA between patients in PCa?BHP group and high?low risk group in TZ (P<0.05), D*and f had no significant differences (P>0.05). ADC and MD showed relatively higher negativity correlations (r were－0.585 and－0.489, P<0.05) with GS of PCa in TZ. ADC exhibited a higher area under the curve (AUC 0.864) compared with D with area under the curve (AUC 0.853), however, the difference is not significant (P>0.05). Of model DKI in diagnose of PCa and BPH, the highest classification accuracy was MD(AUC 0.796). The AUC derived from multiple model parameters in different combination of ADC+D value, ADC+MD value, and ADC+MD+D value were 0.892, 0.884, and 0.897, respectively. ADC and D of IVIM model showed a significance difference between GS≥7 and BPH+(GS=6) with a higher AUC of 0.826 and 0.743. The AUC was 0.851 of the combination of mean ADC and D, 0.846 of combination of mean ADC and MD, the AUC (0.856) of the combination of ADC, D and MD significant higher than any two combined parameters (P>0.05). Conclusions IVIM and DKI models may help to discriminate prostate cancer from BPH, and predict mid?higher GS PCa in TZ. But there is no significant advantage compared with ADC values. It is feasible to stratify the pathological grade of prostate cancer in TZ by mean ADC and MD.
