Objective:To investigate the current status of fertility concerns among early-stage endometrial cancer (EC) and atypical endometrial hyperplasia (AEH) patients with fertility preservation, and analyze its influencing factors.Methods:Convenience sampling was used to select early-stage EC and AEH patients with fertility preservation at Peking University People's Hospital from January to December 2021 as study subjects. The study subjects were surveyed using the General Information Questionnaire, Chinese version of the Reproductive Concerns after Cancer Scale (RCAC), and Social Support Rating Scale (SSRS). Pearson correlation was employed to examine the relationship between fertility concerns and social support in early-stage EC and AEH patients with fertility preservation. Single-factor analysis and multiple linear regression analysis were used to examine the factors influencing fertility concerns in early-stage EC and AEH patients with fertility preservation.Results:A total of 170 questionnaires were distributed, and 167 valid questionnaires were collected, with a valid response rate of 98.24% (167/170). The RCAC and SSRS scores of 167 early-stage EC and AEH patients with fertility preservation were (56.58±10.58) and (34.22±8.21), respectively. Educational level, disease type and staging, marital status, and social support were statistically significant factors influencing fertility concerns among early-stage EC and AEH patients undergoing fertility preservation ( P<0.05), explaining 32.80% of the total variance. Conclusions:Early-stage EC and AEH patients with fertility preservation exhibit high levels of fertility concerns. Clinical practice should develop individualized psychological intervention programs for patients with high education level, unmarried status, high pathological grading, and lack of social support to improve their physical and mental health.

Objective To explore the diagnostic value of hemodynamic and morphological characteristics based on four-dimensional flow magnetic resonance imaging(4D Flow MRI)for unstable saccular intracranial aneurysms(IAs).Methods Seventy-four patients with saccular unruptured intracranial aneurysms(UIAs)who underwent 4D Flow MRI examinations were selected.Morphological and hemodynamic data of the IAs were collected and followed up.According to the follow-up results,patients were divided into stable group and unstable group.Logistic regression analysis was used to identify factors associated with the unstable group,and the diag-nostic performance of the model was evaluated using the receiver operating characteristic(ROC)curves and the area under the curve(AUC).Results The aneurysm diameter,height,width,neck width,and aspect ratio(AR)value in the unstable group were greater than those in the stable group.The wall shear stress(WSS)at the aneurysm neck and the parent artery inflow,as well as the end diastolic velocity(EDV)at the parent artery inflow,were lower in the unstable group than those in the stable group(P＜0.05).Multivariate logistic regression analysis showed that the AR and WSS at the aneurysm neck were independent predictors of unstable IAs(P＜0.05).The combined model of WSS at the aneurysm neck and AR showed an AUC of 0.742[95％confidence interval(CI)0.608-0.875],repre-sented the highest diagnostic performance.Conclusion The hemodynamic characteristics quantified by 4D Flow MRI offer supple-mentary information for risk assessment of IAs.Combining hemodynamic and morphological characteristics is of significant value in identi-fying unstable saccular IAs.

ObjectiveBased on the antidepressant activity， the optimal ratio of Rehmanniae Radix and Lilii Bulbus in Baihe Dihuangtang was optimized and its possible mechanism was preliminarily explored. MethodA total of 100 male mice were randomly divided into normal group， model group， Rehmanniae Radix single decoction group， Lilii Bulbus single decoction group， and 5 different ratios of Baihe Dihuangtang group （Rehmanniae Radix-Lilii Bulbus 5∶6， 5∶5 ， 5∶4， 5∶3， 5∶2）， fluoxetine hydrochloride group. Except for the normal group， the remaining 9 groups were treated with chronic unpredictable mild stress method （CUMS） for 21 consecutive days to establish the depression mouse model.The Rehmanniae Radix single decoction group， Lilii Bulbus single decoction group and 5 different ratios of Baihe Dihuangtang group were administered with corresponding drugs at a dose of 2 g·kg^-1 respectively， and fluoxetine hydrochloride group was administered fluoxetine hydrochloride at a dose of 0.01 g·kg^-1， the normal group and the model group were respectively given an equal volume of normal saline by gavage for 21 consecutive days. The antidepressant effect of Baihe Dihuangtang with different ratios was evaluated by behavioral experiments. Western blot was used to detect the expression levels of brain-derived neurotrophic factor （BDNF） and tyrosine kinase receptor B （TrkB） in hippocampus. The level of total superoxide dismutase （SOD） in hippocampus was detected by hydroxylamine method. The level of reduced glutathione （GSH） in hippocampus was detected by spectrophotometric method. The levels of glutathione peroxidase （GPX） and glutathione S-transferase （GST） in hippocampus was detected by colorimetric method. The level of malondialdehyde （MDA） in hippocampus was detected by thiobarbituric acid method， and preliminary exploration of its antidepressant mechanism. ResultCUMS caused a significant decrease in the preference rate of sugar water and a significant prolongation of forced swimming and tail suspension immobility time （P<0.01）， while the different ratios of Baihe Dihuangtang and the single decoction of Rehmanniae Radix and Lilii Bulbus were significantly reversed to varying degrees. Abnormalities of the above indicators were observed （P<0.05， P<0.01）， especially when the ratio of 5∶6 had the most obvious effect on the above indicators， Moreover， CUMS caused the hippocampal BDNF and the expression of TrkB， SOD and glutathione antioxidant-related indexes were significantly decreased （P<0.01）， and the levels of lipid peroxidation product MDA was significantly increased （P<0.01）. However， the superior ratio of Baihe Dihuangtang （Rehmanniae Radix-Lilii Bulbus 5∶6， 5∶5， 5∶4） and the single decoction of Rehmanniae Radix and Lilii Bulbus significantly reversed the abnormality of the above indicators to varying degrees （P<0.05， P<0.01）. ConclusionIn summary， 5 different ratios of Baihe Dihuangtang and the single decoction of Rehmanniae Radix and Lilii Bulbus can produce antidepressant effect， especially when the ratio of 5∶6 had the most obvious effect on the above indicators， and the antidepressant effect gradually weakens with the proportion of Lilii Bulbus in the recipe decreases， and its mechanism may involve enhancing the nutritional level and antioxidant defense ability of hippocampal central nervous system.

Objective To explore the clinical characteristics and correlation of adult primary nephrotic syndrome (PNS) with thyroid dysfunction,and early identify high-risk adult PNS patients with abnormal thyroid function by clinical data.Methods The clinical data of 101 adult PNS patients in Heji Hospital Affiliated to Changzhi Medical College from March 2015 to December 2017 were retrospectively analyzed.According to the thyroid function,the patients were divided into 2 groups:normal thyroid function group (67 cases) and thyroid dysfunction group (34 cases),including 9 cases with low triiodothyronine (T3) syndrome and 25 cases with subclinical hypothyroidism.The clinical data were compared,and the correlation between thyroid-stimulating hormone (TSH) and 24 h urinary protein,blood albumin and systolic blood pressure were analyzed.Results The incidence of thyroid dysfunction in adult PNS patients was 33.66％ (34/101),including 21 cases of membranous nephropathy,8 cases of minimal change disease,4 cases of IgA nephropathy and 1 case of membranoproliferative nephritis.The 24 h urinary protein in thyroid dysfunction group was significantly higher than that in normal thyroid function group:(8.76 ± 3.62) g vs.(6.96 ± 3.43) g,the albumin was significantly lower than that in normal thyroid function group:(21.82 ± 4.89) g/L vs.(24.49 ± 4.14) g/L,and there were statistical differences (P＜0.05 or ＜0.01);there was no significant difference in gender composition,age,course of disease,systolic blood pressure,diastolic blood pressure,body mass index,hemoglobin,platelet,creatinine,cystatin C,fasting blood glucose,total cholesterol,triacylglycerol,low-density lipoprotein cholesterol (LDL-C),fibrinogen,complement C3,IgG,IgM,IgA,PNS types and comorbidities between 2 groups (P＞0.05).The results of subgroup analysis results showed that the systolic blood pressure in subclinical hypothyroidism patients of thyroid dysfunction group was significantly higher than that in normal thyroid function group and the low T3 syndrome patients of thyroid dysfunction group:(148.16 ± 18.09) mmHg (1 mmHg =0.133 kPa) vs.(139.55 ± 18.77) and (127.78 ± 16.81) mmHg,the 24 h urinary protein was significantly higher than that in normal thyroid function group:(9.00 ± 3.64) g vs.(6.96 ± 3.43) g,the albumin was significantly lower than that in normal thyroid function group:(21.71 ± 5.26) g/L vs.(24.49 ± 4.14) g/L,and there were statistical differences (P＜0.05).Pearson correlation analysis result showed that TSH had no correlation with 24 h urinary protein and systolic blood pressure (r =0.193 and 0.072,P =0.053 and 0.472);however TSH was negatively correlated with albumin (r =-0.340,P =0.001).Conelusions In adult PNS patients with thyroid dysfunction,membranous nephropathy is the most common,followed by minimal change disease.The systolic blood pressure in PNS patients with subclinical hypothyroidism is significantly higher than that in patients with normal thyroid function and low T3 syndrome.In adult PNS patients,the lower the blood albumin is,the more likely they have thyroid dysfunction.
