Objective:To analyze the effects of pelvic floor muscle biofeedback electrical stimulation (PEMS) combined with pelvic floor muscle training (PFMT) and PFMT alone on mild to moderate stress urinary incontinence (SUI) after delivery.Methods:This retrospective study involved 1 087 postpartum women with mild or moderate SUI who were admitted to the Affiliated Hospital of Jining Medical University from January 2017 to January 2021. According to the treatment approaches, they were divided into two groups: the PMES+PFMT group ( n=504) and the PFMT group ( n=583). Chi-square test, independent sample t-test and rank sum test were used to compare the objective indicators (pelvic floor muscle strength test, vaginal dynamic pressure value test, 1-h pad test) and subjective indicators [incontinence impact questionnaire short form (IIQ-7), incontinence questionnaire-urinary incontinence short form (ICI-Q-SF), pelvic organ prolapse/urinary incontinence sexual function questionnaire (PISQ-12)] before, immediate and three months after treatment between the two groups. Results:There was no significant difference between the two groups in the values of vaginal dynamic pressure before treatment, 1-h pad test results and subjective indicators (all P>0.05). Comparison within groups: Indicators were improved in both groups immediate and three months after treatment compared with before treatment, including strength of type Ⅰ muscle [PMES+PFMT group: grade 4 and 5 (normal): 43.5% (219/504) and 42.1% (212/504) vs 1.2% (6/504), χ 2=864.27 and 861.46; PFMT group: grade 4 and 5:19.2% (112/583) and 20.1% (117/583) vs 1.5% (9/583), χ 2=1 148.26 and 1 038.29] and class Ⅱ muscle strength [PMES+PFMT group: 48.4% (244/504) and 50.8% (256/504) vs 4.8% (24/504), χ 2=862.96 and 819.24; PFMT group: 37.4% (218/583) and 38.9% (227/583) vs 5.0% (29/583), χ 2=1 029.47 and 998.54; all P < 0.05].Vaginal dynamic pressure increased [PMES+PFMT group: (89.3±5.4) and (82.2±4.6) vs (67.5±12.7) cmH 2O (1 cmH 2O=0.098 kPa), t=802.13 and 845.54; PFMT group:(80.2±4.3) and (78.6±4.5) vs (66.9±14.2) cmH 2O, t=288.37 and 244.94], and 1-hour urine leakage reduced [PMES+PFMT group: 2.0 g (2.0-3.0 g) and 2.0 g (1.0-3.0 g) vs 6.0 g (5.0-6.0 g), Z=825.39 and 802.13; PFMT group: 4.0 g (3.0-5.0 g) and 3.0 g (3.0-4.0 g) vs 5.0 g (4.0-6.0 g), Z=836.34 and 811.25], and IIQ-7 scores [PMES+PFMT group: scores of 3 (2-4) and 4 (3-4) vs 8 (7-9), Z=959.52 and 825.87; PFMT group: 5 (4-5) and 5 (4-6) vs 8 (7-10), Z=916.27 and 903.18], and ICI-Q-SF score [PMES+PFMT group: 3.5 (3-4) and 4 (3-5) vs 10 (9-12), Z=952.79 and 924.94; PFMT group: 6 (4-7) and 6 (5-7) vs 11 (10-12), Z=1 049.89 and 998.15], and PISQ-12 score [PMES+PFMT group: 10 (7-12) and 9 (7-12) vs 21 (17-24), Z=862.55 and 887.17; PFMT group: 13 (11-16) and 14 (12-16) vs 22 (18-25), Z=1 026.73 and 934.86, all P<0.05) decreased. Compared with the PFMT group, the above indexes were all better in the PMES+PFMT group (all P<0.05). Conclusion:PFMT alone or in combination with PMES can both enhance pelvic floor muscle strength, increase vaginal dynamic pressure, alleviate urine leakage and improve the quality of life and PMES+PFMT is better and more effective.

Multimodality imaging analysis of breast ductal carcinoma in situ within papillomas / 中华放射学杂志

Objective:To investigate the mammography, ultrasound and MRI features of breast ductal carcinoma in situ within papillomas (DCIS-WP) and ductal carcinoma in situ in general (DCIS-IG), and to select the appropriate screening methods for breast cancer.Methods:A retrospective analysis of 134 patients with DCIS-WP and DCIS-IG confirmed by pathology from January 2015 to October 2018 was conducted, including 40 patients with DCIS-WP and 94 patients with DCIS-IG. Mammography, ultrasound and MRI images were analyzed based on BI-RADS criteria, to evaluate the missed diagnosis rate and accuracy rate of three imaging methods, and the consistency of preoperative puncture, intraoperative frozen section and postoperative paraffin section was also observed. Qualitative data were compared using the χ 2 test or Fisher′s exact test. Results:The X-ray missed diagnosis rate of DCIS-WP group and DCIS-IG group was 42.50%（17/40） and 5.32%（5/94）, respectively, while the diagnostic accuracy rate was 22.50%（9/40） and 77.66%（73/94） respectively. The difference between the two groups was statistically significant (χ2=28.268, 35.952, P<0.001). In DCIS-WP group and DCIS-IG group, there were 8 and 2 cases with multiple hypoechoic nodules in the lesions, the difference was statistically significant (χ2=20.819, P<0.001); the missed diagnosis rate was 0 and 24.47%（23/94）, the difference was statistically significant ( P<0.05). On MRI, there were 24 cases and 15 cases of DCIS-WP group and DCIS-IG group with the signs of catheter dilation, 21 cases and 16 cases with multiple papillomas background, 15 cases and 12 cases with sparse internal ring manifestations, 19 cases and 13 cases with different sizes, respectively. The difference between the two groups was statistically significant (χ2=26.378, 17.671, 8.524, 14.530, P<0.05). In DCIS-WP group and DCIS-IG group, 12 cases and 82 cases had the same diagnosis of preoperative puncture, intraoperative frozen pathology and postoperative paraffin pathology respectively, and the difference between the two groups was statistically significant (χ2=44.165, P<0.001). Conclusions:The features of DCIS-WP are different from those of DCIS-IG on mammography and ultrasound. DCIS-WP is likely to be missed on mammography as there is less calcification, while it is easier to be detected by ultrasound. MRI has good diagnostic efficacy for both types of DCIS and is helpful in differentiating them.

Prediction model for distant metastasis of breast cancer based on magnetic resonance imaging / 中国肿瘤临床

Objective: To establish a prediction model for the distant metastasis of breast cancer based on qualitative magnetic reso-nance imaging (MRI) parameters. Methods: A retrospective analysis of 3,032 patients with breast MRI from January 2011 to Decem-ber 2016 in Tianjin Medical University Cancer Institute and Hospital was conducted. After the confirmation of invasive breast cancer, the subjects were divided in 2 groups: metastasis and metastasis-free. A total of 93 patients were included in the metastasis group, and 186 patients without the presence of distant metastasis in the metastasis-free group. We analyzed the correlation between breast cancer molecular subtypes and distant metastasis in the metastasis group. Univariate and Logistic regression analyses of qualitative MRI features were performed for the groups. Subsequently, we used the results to establish prediction models. Results: The results showed that hormone receptor-positive tumors (Luminal type) had a greater tendency to develop bone metastasis in the metastasis group. Triple-negative tumors showed a greater tendency to develop lung metastasis. Human epidermal growth factor receptor 2 gene overexpression cases were more likely to develop liver metastasis. The results of the univariate analysis showed that the type of le-sion, multifocality or multicentricity of the cancer, T1-weighted signal uniformity, T2-weighted signal uniformity, and tumor size were statistically different between the groups (P<0.05). The results of the logistic regression analysis showed that the type of lesion, multi-focality or multicentricity of the cancer, T2-weighted signal uniformity, and tumor size were independent predictors of distant metasta-sis. Based on select independent predictors, we established a prediction model for the distant visceral metastasis of breast cancer. The accuracy, area under the curve, sensitivity, and specificity of the model were 82.8%, 0.801, 85.7%, and 75.0%, respectively. Conclu-sions: The prediction model based on the clinical pathology and MRI features established in this study can predict the distant metasta-sis of breast cancer.

Triple-negative and non-triple-negative breast cancer prediction by mammographic radiomics features / 中华放射学杂志

Objective To develop and validate a radiomics predictive model based on mammogram for preoperative predicting triple-negative breast cancer (TNBC) or non-triple-negative breast cancer (NTNBC). Methods We retrospectively analyzed 459 Chinese women who were diagnosed with invasive breast cancer (confirmed by pathology) during August 2015 to November 2015. Our cohort included 34 TNBC and random selected 102 NTNBC cases. Regions of interest (ROIs) were manually selected from craniocaudal and mediolateral oblique mammograms by radiologists through manual lesion segmentation, and 43 radiomics features were evaluated. Craniocaudal (CC) single-view, mediolateral oblique (MLO) single-view and CC and MLO double-view classification model were constructed respectively. Classification performance was evaluated by the area under receiver operating characteristic curve (AUC), accuracy, sensitivity and specificity. Kruskal-Walls U test and t test were used to compare the radiomics features between TNBC and UTNBC. Results The model that used the combination of both the CC and MLO view images achieved the overall best performance than using either of the two views alone, yielding an AUC of 0.791, accuracy of 0.798, sensitivity of 0.776 and specificity of 0.806 for TNBC comparing with NTNBC. Three features were selected by the model (gray scale span and inverse different moment for CC, roundness for MLO) showed a statistical significance (P<0.05) and AUC>0.6 in the subtype classification. Conclusion This research constructed model based on mammograms classification model can effectively distinguish between TNBC and NTNBC. This model has potential value for breast cancer molecular subtype classification and clinical treatment.

Imaging analysis of fibroblastic and (or) myofibroblastic benign tumors of the breast area / 中华放射学杂志

Objective To characterize the imaging features of fibroblastic and (or) myofibroblastic benign tumors. Methods The imaging manifestations were analyzed in fourteen patients with fibroblastic and (or) myofibroblastic benign tumors of the breast area confirmed by histopathology from July, 2010 to July, 2017. Independent-samples t test was performed to compare ADC values between lesions and normal breast tissue. Results Thirteen cases were adhered to superficial facia of breasts and 1 case was located in the pectoralis. Five lesions were presented as a mass on MRI, 9 lesions were presented as a non-mass. Twelve cases showed low signal intensity on T1WI, 8 cases showed high signal intensity and 4 cases showed moderately or slightly high signal intensity on T2WI. TIC analysis showed that 10 cases had typeⅠenhancement and 4 cases had typeⅢenhancement. There was no difference between mean ADC values of lesions and normal breast tissue (P>0.05). All the cases showed hypoechoic and spiculated margins on ultrasound. Twelve cases were hypovascular ones. Twelve cases underwent mammography. Five cases were presented as a mass and 7 cases were presented as asymmetric. These cases showed equal density without suspicious calcifications. Conclusion The location, MRI, ultrasound and mammography manifestations of fibroblastic and (or) myofibroblastic benign tumors have some characteristics and these imaging findings may help to establish an accurate preoperative diagnosis.

MRI features of mucinous carcinoma and myxoidfibroadenoma of the breast / 中华放射学杂志

Objective To study the features of mucinous carcinoma and myxoidfibroadenoma of the breast on MRI.Methods Fourty patients with pure mucinous carcinoma and myxoidfibroadenoma confirmed by surgical pathology who underwent breast MRI from January 2010 to May 2017 in Tianjin Medical University Cancer Institute and Hospital were analyzed retrospectively, including 26 patients with mucinous carcinoma and 14 patients with myxoidfibroadenoma. By use of the Breast Imaging Reporting and Data System (BI-RADS) lexicon, an analysis of the shape, margin, infiltration to adjacent tissues, the lesion location, signal intensity in the T1WI and fat-suppressed T2WI, dark internal septation, the pattern of time-signal intensity curve (TIC),rim enhancement, delayed internal enhancement, the DWI signal and ADC values was performed. Qualitative data and quantitative data were compared with χ2test and independent sample t test respectively. Results There were significant differences in the margin,dark internal septation,the lesion location, rim enhancement and delayed internal enhancement between mucinous carcinoma and myxoidfibroadenoma(P＜0.05). The shape, signal intensity in the T1WI and fat-suppressed T2WI,infiltration to adjacent tissues, the pattern of TIC, the DWI signal and ADC values were not statistically significant between the two groups(P＞0.05).Conclusion The combination of irregular margin, less frequent dark internal septation, rim enhancement in the early phase, delayed heterogeneous enhancement and the lesion location where was in the shallow layer of fibro-glandular tissue were significant findings for differentiation between mucinous carcinoma and myxoidfibroadenoma.

Prevalence and correlated factors of deficit schizophrenia in community-dwelling patients with schiz-ophrenia / 中华行为医学与脑科学杂志

Objective To explore the prevalence,socio-demographic and clinical characteristics of deficit schizophrenia in Chinese community-dwelling patients with schizophrenia. Methods Five hundred and three community-dwelling patients with schizophrenia were recruited in a cross-sectional study in Yuhua-tai District of Nanjing,and deficit schizophrenia was confirmed by Chinese version of the Schedule for the Deficit Syndrome (SDS). Their socio-demographic and clinical characteristics were collected. All patients' psychopathology was assessed by Positive and Negative Syndrome Scale (PANSS). Results The current prevalence of community-dwelling patients with deficit schizophrenia was 0. 67‰. Deficit schizophrenia had significantly higher hospitalizations((2. 4±1. 3)times,(1. 9±0. 9)times),PANSS negative scores((28. 4± 8. 1),(17. 7±6. 3)),PANSS total score((96. 5±17. 3),(87. 3±18. 1)) than non-deficit schizophrenia(all P<0. 05),while non-deficit schizophrenia had higher currently smoking rate,positive scores,marriage per-centage and age of onset( all P<0. 05) . Further multiple logistic regression analysis indicated that male sex, age of onset,smoking and negative PANSS score were independently associated with deficit schizophrenia. Conclusion The study showed that deficit schizophrenia is very common in Chinese psychiatric outpatients. The results partially support deficit schizophrenia as an independent subtype of schizophrenia.

Prevalence, socio-demographic and clinical correlations of underweight in community-dwelling patients with schizophrenia / 中国神经精神疾病杂志

Objective This study examined the prevalence of underweight and its related risk factors of community-dwelling patients with schizophrenia. Methods Five hundred and three community-dwelling patients with schizophrenia and 323 healthy controls were recruited in a cross-sectional study. Body mass index less than 18.5 was defined as underweight. Their demographic and clinical data including anthropometric data, plasma glucose and lipid parameters were collected. The Positive and Negative Syndrome Scale (PANSS) was used to assess patients' psychopathology. Results The prevalence of underweight was 9.9% (50/503) in schizophrenia patients versus 1.5% (5/323) in the control group ( P<0.01). Further logistic regression analysis showed that male ( OR=2.43, 95%CI:1.74~3.39), smoking behavior (OR=1.50, 95%CI: 1.21~1.86), hospitalization times (OR=1.18, 95% CI: 1.06~1.31), PANSS negative score (OR=1.09, 95% CI: 1.04~1.14) were significant predictors for underweight (all P<0.05). Conclusion The prevalence of underweight is higher in Chinese patients with schizophrenia than in the general population. Some demographic and clinical variables are risk factors for underweight in schizophrenia.

Objective To investigate the magnetic resonance imaging (MRI) features and differential diagnosis of axillary schwannomas, and analyze the causes of misdiagnosis. Methods A retrospective study from October 2014 to October 2017 was performed in 5 patients with axillary schwannomas, confirmed by surgery and pathology, in whom clinically suspected axillary metastases have been diagnosed. All the patients underwent breast MRI to summarize the key points of diagnosis and differential diagnosis. Results Five tumors located in neurovascular bundles extending along the brachial plexus nerve distribution. The tumors presented as single, spindle or ovoid masses, well-circumscribed margins in 4 cases, entering and exiting nerve signs in 5 cases, the split fat sign in 4 cases, vascular compressed sign in 5 cases, and target sign in 1 case. The tumors were isointense or slight hypointense on T1WI compared to the adjacent muscle. Three tumors manifested heterogeneous slight hyperintense, 1 tumor was slight hyperintense, and the target sign was seen in 1 tumor on T2WI. Diffusion-weighted image was heterogeneous hyper or slightly hyper-intense. When b＝500 and 1 000 s/mm2, the apparent diffusion coefficient (ADC) was (1.40 - 2.23) × 10 -3mm2/s and (1.31 -2.94) × 10-3mm2/s respectively. All the 5 tumors manifested persistent enhancement on dynamic contrast-enhanced MRI (DCE-MRI). Three tumors were heterogeneously enhanced, and 2 tumors were circularly enhanced. Conclusions Axillary schwannomas has certain characteristics which can be helpful for the identification of metastatic lymph nodes.

Treatment patterns and affecting factors in breast cancer patients over 65-years of age / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To explore different therapies and affecting factors in breast cancer patients ≥ 65 years old.</p><p><b>METHODS</b>To retrospectively analyze the clinical characteristics, treatments, comorbidity and survival rate of 126 female breast cancer patients over 65 years old who underwent surgical operation in our hospital from January 2009 to December 2010. To compare and analyze the differences in the treatment patterns, and find out the affecting factors.</p><p><b>RESULTS</b>One hundred and twenty-six cases were included in this retrospective study, and they were divided into two groups according to age: 65-74 years old group (71 cases) and >74 years group (55 cases). Most patients in the two groups received modified radical mastectomy (84.5% and 89.1%); 73.2% and 54.5% of patients received adjuvant chemotherapy in the two groups, respectively. 67.6% and 61.8% of the patients had adjuvant endocrine therapy respectively. 19.7% and 7.3% of the patients received radiotherapy, respectively. Chemotherapy in elderly breast cancer patients was correlated with age, pathological types, progesterone receptor (PR) status and comorbidity. Radiotherapy in elderly breast cancer patients was related to age, surgical patterns, TNM stage and lymph node status. Multivariate analysis showed that age, pathological types, PR expression and comorbidity were independent factors affecting choice of chemotherapy in elderly breast cancer patients (P < 0.05 for all). Age and surgical patterns were independent factors affecting choice of radiotherapy (P < 0.05 for all). The 3-year disease-free survival (DFS) rate and overall survival (OS) rate in these patients were 91.3% and 92.0%, respectively. Furthermore, endocrine therapy was related to 3-year DFS rate (P = 0.038) and age was correlated with 3-year OS rate (P = 0.037) in these elderly patients.</p><p><b>CONCLUSIONS</b>Breast cancer in the elderly patients receive similar surgery and endocrine therapy, but the elderly patients are less likely to have chemotherapy and radiotherapy, due to age, PR expression, pathological types, surgical patterns and comorbidity. Only age contributes to the lower 3-year overall survival rate in >74-year old patients.</p>

Diagnostic value of HbA1C and fasting plasma glucose as early screening parameters for diabetes mellitus / 中华内分泌代谢杂志

The validity of HbA1C and fasting plasma glucose(FPG)for screening of diabetes in community population was investigated.A total of 1 794 subjects from two sub-districts of Yangpu District,Shanghai,underwent a 75 goral glucose tolerance test(OGTT)and HbA1C determination.Based on 1999 World Health Organization criteria,there were 1 411 subjects with normal glucose tolerance(NGT),111 impaired fasting glucose(IFG),73 impaired glucose tolerance(IGT),33 IFG+IGT,and 166 diabetes.According to the receiver operating characteristic curve,the optimal cut-point of FPG for diagnosing diabetes was 6.15 mmol/L with sensitivity of 89.0%,specificity of 92.8%,and area under the curve of 0.959.The cut-point of HbA1C for diagnosing diabetes was 6.5% with a sensitivity and specificity of 71.1% and 80.2%.The area under the curve was 0.822.The screening model using FPG ≥6.1mmol/L and HbA1C≥6.5% had sensitivity of 66.9% and specificity of 97.0%.When the model was FPG ≥6.1 mmol/L or HbA1C ≥6.5%,the sensitivity and specificity was 96.3% and 76.7% respectively.The results suggest that both FPG and HbA1C have good value for screening diabetes in community,and FPG combined with HbA1C may further promote diagnostic efficacy.
