ABSTRACT
Objective To explore the method and clinical value of sentinel lymph node biopsy for penile carcinoma guided by multispectral separate-merge guided surgery device (MGS).Methods The clinical data of 7 patients with sentinel lymph node biopsy of penile cancer guided by MGS from April 2017 to April 2018 were analyzed retrospectively at First Hospital of Shanxi Medical University.They were 62-78 years old,with an average age of 65 years.All of carcinoma was located in the glans or coronal sulcus,which diameter was 1.0-3.5 cm,with an average of 2.5 cm.Three cases of inguinal lymph nodes could be non-palpable and the others palpable.All patients were injected 0.25 ml (2.5 mg/ml) of indocyanine greensolution with 1 ml syringe at 12,4,6 and 9 points in the proximal normal skin of penile tumors.Immediately,the imaging probe was aligned with the injection point to observe the dynamic changes of fluorescence image on MGS display.Results There were 14 sides of groin in 7 patients,except for 1 side without images,other 13 sides developed well.The images displayed by MGS include visible image,fluorescent image and merged image,and the merged image was green pseudo color.According to the dynamic changes of the image,it could be divided into five parts:injection point,penile body,pubic symphysis,inguinal region and sentinel lymph node.In 13 well-developed sides,fluorescence gradually disappeared in other parts about 15 minutes after injection,and the location of sentinel lymph nodes was determined in vitro by gradually consolidating and fixing the fluorescence images in the inguinal region.The lymph node-like tissue with strong fluorescence intensity was observed immediately after the skin incision.There was a clear boundary between the lymph node-like tissue and the surrounding tissue.Along this boundary,lymph nodes were separated,ligated,excised.No lymph nodes were found on the undetected side.Postoperative pathology confirmed that lymph nodes were located by fluorescence imaging in vitro and traced by fluorescence imaging in vivo,the coincidence rate was 100％.There were residual fluorescent tissues on three sides and lymphatic vessels were removed.Conclusions MGS-assisted intraoperative fluorescence imaging could improve the doctor's visual depth so that physicians can real-time,dynamic,accurate in vitro location and in vivo tracking of sentinel lymph nodes of penile cancer.
ABSTRACT
Objective To analyze the overactive bladder symptom score (OABSS) in evaluating bladder dysfunction in the different stages among type 2 diabetes mellitus patients,and to explore the value of bladder hyperactivity symptom score in screening early diabetic bladder dysfunction.Methods A total of 1 157 patients with type 2 diabetes mellitus,aged 40-88 yearswith mean age of 60.2 years,were enrolled from October 2013 to October 2016.The survey included the patients' characteristics,past history,current history,OABSS and quality of life (QOL) index scores.T test,single factor analysis of variance and multiple regression analysis are used to analyze the results.Results As many as 1 157 were qualified for final statistical analysis.OABSS is 1.94 ± 1.23 in group with diabetes duration ＜ 10 years,3.24 ± 1.45in group with diabetes duration 10-20 years,and 4.00 ± 1.72 in group with diabetes duration ＞ 20 years.The differences of OABSS in the different duration of diabetes was statistically significant.As diabetic duration increased,OABSS value increased (F =48.419,P ＜ 0.001).The difference of OABSS in the different HbA1c level,age and concurrent peripheral neuropathy was statistically significant.There was no significant difference of OABSS in the different BMI and distinct therapies.There was no significant difference of OABSS in diabetes with hypertension and without hypertension,with cardiopathy and without cardiopathy,with cerebrovascular disease (CVD) and without CVD,with hyperhpemia and without hyperlipemia.The significant factors were used to make multivariate analysis.The results showed that the duration of diabetes,HbA1 c level,age,peripheral neuropathy were still statistically significant.Standardized partial regression coefficient of diabetic duration was 0.366.OABSS was positively correlated with QOL score (r =0.434,P ＜ 0.001).Conclusions The related symptoms in OABSS with diabetic bladder dysfunction is correlated with the duration of diabetes,HbA1c level,age,concurrent peripheral neuropathy among type 2 diabetes.The duration of diabetes was the most significant factor.OABSS is likely to be one of the tools to assess the early symptoms of diabetic bladder dysfunction.

ABSTRACT
Objective:To explore the mediating effect of inferiority feelings on the relationship between child-hood trauma and fear of intimacy in college students.Methods:Totally 420 college students (72 males and 324 fe-males,aged 18 to 24)from Langfang Normal School were assessed with the Feelings of Inadequacy Scale(FIS), Childhood Trauma Questionnaire(CTQ)and Fear-of-Intimacy Scale(FIS).The regression analysis and Bootstrap were used to test the mediating effect of inferiority feelings on the relationship between childhood trauma and fear of intimacy.Results:The total scores of CTQ and the scores of 4 childhood trauma factors were positively correla-ted with fear of intimacy score and feeling of inferiority score(r =0.18 -0.55,Ps <0.05).Feeling of inferiority scores were positively correlated with fear of intimacy scores (r =0.24 -0.44,Ps <0.05).The childhood trauma was positively associated with fear of intimacy (β=0.31,P <0.01).In addition,feeling of inferiority fully media-ted the relationship between childhood trauma and fear of intimacy,the value of mediating effect was 34%.Conclu-sion:Feeling of inferiority may play a mediating role between childhood trauma and fear of intimacy in college students.
ABSTRACT
<p><b>BACKGROUND</b>Because invasion and metastasis of cancer threaten seriously human's life, it is of more important clinical significance to understand and evaluate the biologic behavior of can-(cer) correctly. Abnormal expression of E-cadherin and β-catenin plays important roles in invasion and metastasis of cancer. The objective of this study is to investigate their expression in non-small cell lung cancer (NSCLC) and to find out their correlation with histological type, cell differentiation, metastasis and prognosis of NSCLC.</p><p><b>METHODS</b>The expression of E-cadherin and β-catenin was detected in 129 NSCLC tissues by high sensitive S-P immunohistochemical method.</p><p><b>RESULTS</b>The abnormal expression rate of E-cadherin and β-catenin was 62.0% and 65.1% respectively. The abnormal expression rate of E-cadherin in squamous cell carcinoma was much higher than that in adenocarcinoma (P < 0.05). The abnormal expression rate of E-cadherin and β-catenin in poorly differentiated cells was significantly higher than that in well and moderately differentiated cells (P < 0.05, P < 0.05). Stage III/IV NSCLC showed markedly higher abnormal expression rate of E-cadherin and β-catenin than stage I/II NSCLC did (P < 0.01, P < 0.01). The abnormal expression rate of E-cadherin and β-catenin in patients with lymphatic metastasis was significantly higher than that in those without lymphatic metastasis (P < 0.05, P < 0.01). The mean survival duration and 5-year survival rate in patients with normal E-cadherin and β-catenin expression were remarkably higher than those in patients with abnormal expression (P < 0.05, P < 0.01).</p><p><b>CONCLUSIONS</b>The abnormal expression of E-cadherin and β-catenin is closely related to histological type, differentiation and metastasis in NSCLC. Detection of their expression might be helpful to predict prognosis of NSCLC.</p>
