ObjectiveTo explore the value of a multimodal MRI-based radiomics nomogram for differentiating human epidermal growth factor receptor-2 （HER-2） negative breast cancer molecular subtypes.MethodsA retrospective analysis was conducted on 190 patients with HER-2 negative breast cancer who underwent multimodal MRI examination， and the patients were divided into two molecular subtype groups： a HER-2 low expression group （n=108） and a HER-2 zero expression group （n=82）. The cases were randomly stratified and sampled at a ratio of 7∶3 and divided into a training set of 133 cases and a testing set of 57 cases. The clinical and radiological features of the patients were collected， the radiomics features based on T2-weighted imaging （T2WI）， diffusion-weighted imaging （DWI）， and dynamic contrast-enhanced （DCE）-MRI were extracted， and the clinical-radiological model， unimodal radiomics model， multimodal radiomics model， and combined model were constructed respectively. Then the nomogram combined multimodal radiomics signature （radsocre） with clinical-radiological features was used to construct a visualized predictive model， and the area under the curve （AUC） was used to compare the effectiveness of different models in distinguishing HER-2 low expression and zero expression subtypes.ResultsA significant difference in radscore was demonstrated between the HER-2 low and HER-2 zero expression groups in both the training （P<0.000 1） and testing sets （P<0.01）. The AUC of the multimodal radiomics model in the training set and the testing set were 0.914 and 0.836， respectively， which was superior to any unimodal radiomics model. The nomogram demonstrated great diagnostic efficacy （AUC=0.930 in training set； AUC=0.865 in testing set）.ConclusionA multimodal MRI-based nomogram incorporating radsocre and clinical-radiological features can accurately distinguish the subtypes of HER-2 negative breast cancer.

ObjectiveTo investigate the distribution of traditional Chinese medicine （TCM） syndrome patterns among postmenopausal women with dyslipidemia， and to examine the correlations of lipid parameters with bone mineral density （BMD） and bone metabolism markers across common TCM syndrome patterns， thereby providing a clinical reference for individualized integrative traditional Chinese and western medicine interventions stratified according to TCM syndrome patterns. MethodsA multi-center cross-sectional study was conducted among postmenopausal women aged 45-64 years with dyslipidemia. TCM syndromes were determined using a scale-based scoring method. BMD measurements were collected， and fasting venous blood samples were assayed for lipid parameters including total cholesterol （TC）， triglycerides （TG）， high-density lipoprotein cholesterol （HDL-C）， and low-density lipoprotein cholesterol （LDL-C）， and bone metabolism biomarkers including osteocalcin （OST）， total procollagen type Ⅰ N-terminal propeptide （P1NP）， alkaline phosphatase （ALP）， bone-specific alkaline phosphatase （BALP）， β-isomerized C-terminal telopeptide of type Ⅰ collagen （β-CTX）， 25-hydroxyvitamin D ［25（OH）D］， and thyroid-stimulating hormone （TSH）. Chi-square tests were used to compare the distribution of dyslipidemia across different TCM syndromes. Spearman's rank correlation analysis was performed to evaluate the correlations between TCM syndrome patterns and dyslipidemia， as well as the correlations of lipid parameters with BMD and bone metabolism markers within each syndrome pattern. ResultsA total of 506 postmenopausal women with dyslipidemia were included， comprising 172 cases of spleen-kidney yang deficiency syndrome （33.99%）， 163 cases of phlegm-turbidity obstruction syndrome （32.21%）， 118 cases of liver-kidney yin deficiency syndrome （23.32%）， 33 cases of qi stagnation and blood stasis syndrome （6.52%）， and 20 cases of yin deficiency and yang hyperactivity syndrome （3.95%）. Phlegm-turbidity obstruction syndrome was negatively correlated with TC abnormality （r=-0.120， P=0.007） and positively correlated with TG abnormality （r=0.246， P＜0.001）. Spleen-kidney yang deficiency syndrome and liver-kidney yin deficiency syndrome were both negatively correlated with TG abnormality （r=-0.101， P=0.023； r=-0.116， P=0.009， respectively）. Further correlation analysis confirmed that phlegm-turbidity obstruction syndrome was negatively correlated with TC abnormality （r=-0.120） and significantly positively correlated with TG abnormality （r=0.246）. Both the spleen-kidney yang deficiency syndrome and liver-kidney yin deficiency syndrome were negatively correlated with TG abnormality （r=-0.101 and r=-0.116， respectively）. In patients with phlegm-turbidity obstruction syndrome， HDL-C was negatively correlated with BMD at the left femoral neck （r=-0.178， P=0.023） and at left total hip （r=-0.190， P=0.015）. In patients with liver-kidney yin deficiency syndrome， TG was positively correlated with BMD at the lumbar spine （L1-L4） and left total hip （r=0.214， P=0.020； r=0.221， P=0.016， respectively）. More significant correlations were observed in patients with spleen-kidney yang deficiency syndrome， TG was positively correlated with ALP （r=0.210， P=0.006）； TC was positively correlated with TSH and 25（OH）D （r=0.153， P=0.045； r= 0.231， P=0.002， respectively）； HDL-C was positively correlated with OST and 25（OH）D （r=0.156， P=0.040； r=0.228， P=0.003， respectively）； and LDL-C was positively correlated with TSH and 25（OH）D （r=0.156， P= 0.041； r=0.182， P=0.017， respectively）. In patients with liver-kidney yin deficiency syndrome， HDL-C was negatively correlated with TSH （r=-0.204， P=0.027）. ConclusionThe association between dyslipidemia and skeletal health in postmenopausal women varies across TCM syndromes. Lipid abnormalities in women with phlegm-turbidity obstruction syndrome or liver-kidney yin deficiency syndrome are accompanied primarily by site-specific alterations in BMD， whereas those in women with spleen-kidney yang deficiency syndrome are reflected mainly in changes in bone metabolism markers. These findings suggest that targeted intervention strategies should be developed according to TCM syndrome characteristics for postmenopausal women with dyslipidemia.

Objective It compared the power consumption and electrical parameters between Thulium fiber laser devices(TFL)and Holmium laser devices(HoL)in transurethral enucleation of prostate(TUEP).Methods A sin-gle surgeon conducted TUEP by THL or HoL in 10 patients respectively.The enucleation efficiency,the laser energy output and the electric parameters were recorded and analyzed.Results The data from both groups of surgeries were tested for normal distribution,and the t-test found that the difference in the enucleation efficiency between the two surgeries was not statistically significant(P=0.818),and the energy consumption indexes of the two devices were comparable.The difference in the total kilojoules of laser emission between the two lasers during surgery was not statistically significant(P=0.148),but the power consumption of the thulium laser was about one-tenth of that of the holmium laser(P＜0.001),suggesting that the former utilised electrical energy significantly more efficiently than the latter.The maximum current of the HoL was significantly higher than that of the TFL(P＜0.001),requiring a spe-cial high-power power outlet.Conclusion TFL was superior to HoL in terms of lower power consumption,higher en-ergy-efficient and electrical convenient in transurethral enucleation of the prostate.
