ABSTRACT
Resumo Fundamento: A disfunção hepática é uma variável postulada de prognóstico desfavorável na cardiomiopatia dilatada (CMD). Objetivo: Este estudo teve como objetivo investigar o valor prognóstico do escore albumina-bilirrubina (ALBI), um modelo relativamente novo para a avaliação da função hepática, em pacientes com CMD idiopática. Métodos: Um total de 1.025 pacientes com CMD idiopática foram incluídos retrospectivamente e divididos em três grupos com base nos escores de ALBI: grau 1 (≤ −2,60, n = 113), grau 2 (−2,60 a −1,39, n = 835) e grau 3 (> −1,39, n = 77). Foi analisada a associação do escore ALBI com eventos clínicos adversos maiores (ECAM) intra-hospitalares e mortalidade a longo prazo. Valor de p inferior a 0,05 foi considerado estatisticamente significativo. Resultados: A taxa de ECAM intra-hospitalares foi significativamente maior nos pacientes com grau 3 (2,7% versus 7,1% versus 24,7%, p < 0,001). A análise multivariada mostrou que o escore ALBI foi um preditor independente para ECAM intra-hospitalares (odds ratio ajustada = 2,80, IC 95%: 1,63 - 4,80, p < 0,001). Após seguimento mediano de 27 meses, 146 (14,2%) pacientes morreram. A curva de Kaplan-Meier indicou que a taxa cumulativa de sobrevida a longo prazo foi significativamente menor em pacientes com grau mais alto de ALBI (log-rank = 45,50, p < 0,001). O escore ALBI foi independentemente associado à mortalidade a longo prazo (hazard ratio ajustada = 2,84, IC 95%: 1,95 - 4,13, p < 0,001). Conclusão: O escore ALBI, como modelo de risco simples, pode ser considerado uma ferramenta de estratificação de risco para pacientes com CMD idiopática.
Abstract Background: Liver dysfunction is a postulated variable for poor prognosis in dilated cardiomyopathy (DCM). Objective: This study aimed to investigate the prognostic value of the albumin-bilirubin (ALBI) score, a relatively new model for evaluating liver function, in patients with idiopathic DCM. Methods: A total of 1025 patients with idiopathic DCM were retrospectively included and divided into three groups based on ALBI scores: grade 1 (≤ −2.60, n = 113), grade 2 (−2.60 to −1.39, n = 835), and grade 3 (> −1.39, n = 77). The association of ALBI score with in-hospital major adverse clinical events (MACEs) and long-term mortality was analyzed. P-value less than 0.05 was considered statistically significant. Results: The in-hospital MACEs rate was significantly higher in the grade 3 patients (2.7% versus 7.1% versus 24.7%, p < 0.001). Multivariate analysis showed that ALBI score was an independent predictor for in-hospital MACEs (adjusted odds ratio = 2.80, 95%CI: 1.63 - 4.80, p < 0.001). After a median 27-month follow-up, 146 (14.2%) patients died. The Kaplan-Meier curve indicated that the cumulative rate of long-term survival was significantly lower in patients with higher ALBI grade (log-rank = 45.50, p < 0.001). ALBI score was independently associated with long-term mortality (adjusted hazard ratio = 2.84, 95%CI: 1.95 - 4.13, p < 0.001). Conclusion: ALBI score as a simple risk model could be considered a risk-stratifying tool for patients with idiopathic DCM.
ABSTRACT
Objective@#Some pharmacological treatments are ineffective in parts of patients with major depressive disorder (MDD), hence this needs prediction of effective treatment responses. The study aims to examine the relationship between dynamic functional connectivity (dFC) of the hippocampal subregion and antidepressant improvement of MDD patients and to estimate the capability of dFC to predict antidepressant efficacy. @*Methods@#The data were from 70 MDD patients and 43 healthy controls (HC); the dFC of hippocampal subregions was estimated by sliding-window approach based on resting-state functional magnetic resonance imaging (R-fMRI). After 3 months treatment, 36 patients underwent second R-fMRI scan and were then divided into the response group and non-response group according to clinical responses. @*Results@#The result manifested that MDD patients exhibited lower mean dFC of the left rostral hippocampus (rHipp.l) compared with HC. After 3 months therapy, the response group showed lower dFC of rHipp.l compared with the non-response group. The dFC of rHipp.l was also negatively correlated with the reduction rate of Hamilton Depression Rating Scale. @*Conclusion@#These findings highlighted the importance of rHipp in MDD from the dFC perspective. Detection and estimation of these changes might demonstrate helpful for comprehending the pathophysiological mechanism and for assessment of treatment reaction of MDD.
ABSTRACT
OBJECTIVE@#To investigate the changes of tetraspanin 8 (TSPAN8) expression levels and its role in lipid metabolism during the development of non-alcoholic fatty liver disease (NAFLD).@*METHODS@#Thirty male C57BL/6J mice were randomly divided into normal diet group and high-fat diet (HFD) group (n=15), and after feeding for 1, 3, and 6 months, the expression levels of TSPAN8 in the liver tissues of the mice were detected with Western blotting. In a HepG2 cell model of NAFLD induced by free fatty acids (FFA), the effect of TSPAN8 overexpression on lipid accumulation was examined using Oil Red O staining and an automated biochemical analyzer, and the mRNA expressions of the key genes involved in lipid metabolism were detected using qRT-PCR.@*RESULTS@#Western blotting showed that compared with that in mice with normal feeding, the expression of TSPAN8 was significantly decreased in the liver tissues of mice with HFD feeding for 3 and 6 months (P < 0.05). In HepG2 cells, treatment with FFA significantly decreased the expression of TSPAN8 at both the mRNA and protein levels (P < 0.01). TSPAN8 overexpression in FFA-treated cells showed significantly lowered intracellular triglyceride levels (P < 0.001) and obviously reduced mRNA expression of fatty acid transport protein 5 (FATP5) (P < 0.01). The expression of FATP5 was significantly increased in FFA-treated cells as compared with the control cells (P < 0.001).@*CONCLUSION@#TSPAN8 is involved in lipid metabolism in NAFLD, and overexpression of TSPAN8 may inhibit cellular lipid deposition by reducing the expression of FATP5.

With the increasing incidence of upper gastric cancer and early gastric cancer, surgeons have gradually paid attention to the selection of appropriate digestive tract reconstruction methods. At present, the safety of surgery is no longer the main aim pursued by surgeons, and the focus of surgery has gradually changed to postoperative quality of life. Surgical procedures for upper gastric cancer include total gastrectomy (TG) and proximal gastrectomy (PG). Roux-en-Y anastomosis is recommended for digestive tract reconstruction after TG. The classic method of digestive tract reconstruction after PG is distal residual stomach and esophageal anastomosis. However, to prevent esophageal reflux caused by PG, a lot of explorations have been carried out over the years, including tubular gastroesophageal anastomosis, double-flap technique (Kamikawa anastomosis), interposition jejunum, double-tract reconstruction and so on. But the appropriate method of digestive tract reconstruction for upper gastric cancer is still controversial. In this paper, based on literatures and our clinical experience, the selection, surgical difficulties and techniques of digestive tract reconstruction after PG are discussed.

Objective:To evaluate the efficacy and side effects of PD-1 monoclonal antibody in the treatment of advanced metastatic renal cell carcinoma in China.Methods:The clinical data of 117 patients with advanced metastatic renal cell carcinoma (mRCC) treated with PD-1 monoclonal antibody from October 2016 to February 2022 were retrospectively analyzed. There were 87 males (74.4%) and 30 females (25.6%), with an average age of (57.9±10.9) years old, BMI of (23.6±3.4) kg/m 2and smoking history of 79 (67.5%). There were 44 cases (37.6%) with hypertension, 19 (16.2%) cases of diabetes. The ECOG score of 59.8% (70/117) patients was 0, 33.3% (39/117) was 1, 4.3% (5/117) was 2, and 2.5% (3/117) was 3. The pathological type of 104 cases were renal clear cell carcinoma (ccRCC), 8 cases of papillary renal cell carcinoma, 2 cases of chromophobe cell carcinoma, 2 cases of collecting duct carcinoma and 1 case of eosinophilic cell carcinoma. The general condition of the overall population and the overall survival (OS) of relevant subgroups were analyzed. Secondary goals included progression free survival (PFS), objective response rate (ORR), adverse reactions, overall survival (OS), and progression free survival (PFS). Results:65.8% (77 / 117) of the patients chose targeted combined with PD-1 monoclonal antibody in the first-line treatment. The main targeted drugs were acitinib (81.8%, 63 / 77), tirelizumab (37.6%, 29 / 77) and cindilimab (25.9%, 20 / 77). After first-line treatment, 19.6.1% (23 / 117) patients needed to be converted to second-line treatment, and 15 patients changed the type of PD-1 antibody during treatment. In addition, the targeted drug of combined therapy was replaced by acitinib in 8 patients. The main causes of drug withdrawal were disease progression (70.7%, 29 / 41) and death (29.2%, 12 / 41). The median OS of the overall population was 35.6 (19-60) months and PFS was 12.1 (1-60) months. The ORR of the overall population was 47.8% (56 / 117). 4.2% (5/117) patients had complete remission, another 17.0% (20/117) patients were in stable condition, and 43.5% (51 / 117) patients were in partial remission. In the first-line treatment, the median PFS time of targeted combined with PD-1 monoclonal antibody was 12.6 (1-30) months, the median PFS time of PD-1 single drug immunotherapy was 10.5 (1-60) months. In the second-line treatment, the PFS of patients treated with PD-1 monoclonal antibody was 10.1 (4-19) months, and that of patients treated with PD-1 monoclonal antibody combined with targeted therapy was 11.7 (1-25) months. The most common adverse reactions were elevated blood pressure (18.5%, 23 / 124), followed by hypothyroidism (15.3%%, 19/124), rash (14.5%, 18 / 124), elevated transaminase (10.5%, 13 / 124) and bone marrow suppression (9.7%, 12/124). 9.4% (11 / 117) patients needed to reduce the related adverse reactions by interrupting the treatment control of PD-1 monoclonal antibody.Conclusions:The safety and efficacy of PD-1 monoclonal antibody in domestic patients are better, and the side effects are less. The efficacy and safety of PD-1 monoclonal antibody combined with targeted therapy in the real world population are consistent with many key clinical trials abroad. PD-1 monoclonal antibody combined with targeted drugs can be popularized in the domestic MRCC population.
ABSTRACT
A patient aged 68 years old presented urinary frequency, urgency, and gross hematuria for 1 month, with initial PSA of 72.72 ng/ml and alkaline phosphatase (ALP)of 114 U/L. Prostate biopsy pathology showed small cell neuroendocrine carcinoma of prostate. The patient was immediately administered 6 cycle of chemotherapy including etoposide and cisplatin combined with medical castration. The CDK4 gene was detected 1.99 times amplification by peripheral blood free DNA (cfDNA)gene analysis. The chemotherapy was followed by parbosini therapy. The number and density of bone metastases continued to decrease significantly by bone scan at 3 and 6 months after treatment, with a continuous decline of ALP and PSA. After 1 year of follow-up, pelvic MRI and bone systemic imaging indicated stable lesions, with PSA of 0.05 ng/ml and ALP of 59 U/L.
ABSTRACT
Objective:To investigate the safety and effectiveness of tension adjustment technique using anatomical landmarks during retropubic midurethral synthetic sling.Methods:The data of 36 consecutive female patients with urinary incontinence, who had underwent retropubic midurethral synthetic sling procedure from January to August 2019 were analyzed retrospectively. The mean age was (60.83±7.93) years old and the body mass index was (24.43±2.44) kg/m 2. Among the recruited subjects, 36 had positive stress test and Marshall-Marchetti test. 20 (55.6%) were pure stress urinary incontinence, and 16 (44.4%) were mixed urinary incontinence. The severity of incontinence was classified into mild (5 cases, 13.9%), moderate (14 cases, 38.9%), severe (13 cases, 36.1%) and very severe (4 cases, 11.1%) using one-hour pad tests. Urodynamics were performed in 17 cases, with 5 (29.4%) presented detrusor overactivity, 3 (17.7%) possessed intrinsic sphincter deficiency. For each case, the tension of the sling was adjusted based on the anatomical landmarks, i. e. using an angled clamp attached closely to the pubic symphysis ventrally and the tip parallel to the edge of hymen dorsally. All patients were catheter-free right after the procedure. The subjective and objective effectiveness, and safety (the rate of urinary retension after surgery and postvoid residual volume 3 months later) were evaluated.The subjective cure rate was was defined as complete leakage free or very mild leakage during excessive bladder filling and fierce cough. The subjective effectiveness was defined as over 50% improvement of the leakage symptom. The objective cure rate was defined as a negative stress test. Results:For all 36 patients, the median hospital stays was 8 (5-95)h. No bladder perforation or transfusion cases. All patients were catheter-free right after the procedure, with no incidence of urinary retention. 27 patients completed a 3-month follow-up, with 22 had post-void residual data, 23 had subjective effectiveness data and 23 had objective effectiveness data. The median post-void residual was 7.5 (5-64) ml, subjective cure rate was 91.3% (21/23), and objective cure rate was 95.7% (22/23). 8.7% (2/23) reported difficult urination alleviated without the necessity of clinical interference. No urethra erosion or vagina extrusion was found. At 2-year follow-up, 34 patients completed assessment by phone. The subjective cure rate was 91.2% (31/34), with only 2.9% (1/34) reported difficult urination. Besides, at 3-month follow-up, there was no difference regarding the subjective cure rate [100.0%(12/12) vs. 81.8%(9/11)]or objective cure rate [91.7%(11/12) vs. 100.0%(11/11)] between patients with stress and mixed incontinence. No difference was noted among patients with mild, moderate, severe and very severe leakage[75.0% (3/4) vs. 100.0%(6/6) vs. 90.0%(9/10) vs. 100.0%(3/3)]. Of the 12 cases with urodynamic records, the presence of detrusor overactivity [66.7%(2/3) vs. 88.9%(8/9)] or intrinsic sphincter deficiency [0(0/1) vs. 90.9%(10/11)] did not significantly affected the cure rate of the procedure. At 2-year follow-up, there was no difference regarding the subjective cure rate between patients with stress and mixed incontinence [94.7%(18/19) vs. 86.7%(13/15)]. No difference was also noted among patients with mild, moderate, severe and very severe leakage[80.0%(4/5) vs. 100.0%(13/13) vs. 83.3%(10/12) vs. 100.0%(4/4)]. Of the 16 cases with urodynamic records, the presence of detrusor overactivity [60.0%(3/5) vs. 90.9%(10/11)]or intrinsic sphincter deficiency [66.7%(2/3) vs. 84.6%(11/13)]did not significantly affected the cure rate of the procedure.Conclusions:Tension adjustment using anatomic landmarks during sling procedure is safe and feasible for urinary incontinence, with minimum complications and residual volume, and high subjective/objective cure rate.
ABSTRACT
Lymphatic metastasis is commonly encountered in prostate cancer. However, prostate cancer along with lymph node involvement in anterior prostatic fat is rarely reported. Here we present one case. Lymphadenectasis was noticed during robot-assisted laparoscopic radical prostatectomy. Histopathologic examinations confirmed lymph node metastasis in anterior prostatic fat. The patient was assigned to adjuvant androgen deprivation therapy. At 16-month follow-up, biochemical recurrence has not occurred. Detection of lymph node metastasis in anterior prostatic fat of prostate cancer patients provides valuable information for adequate postoperative staging and management.
ABSTRACT
The incidence of prostate cancer has increased over the past several years and it has become a major disease that seriously harms male health. Advanced prostate cancer is a heterogeneous disease with poor outcomes, the median overall survival of advanced prostate cancer usually less than two years. Clinical challenges include determining the optimal sequencing of systemic therapies and implementing biomarker-driven treatment approaches. The emergence of precision treatment has brought about a diagnosis and treatment strategy based on molecular testing, which provides the possibility for the formulation of individualized treatment plans.
ABSTRACT
Objective@#The connectivity alterations in the putamen were found in revealing the neural correlates of attention-deficit/hyperactivity disorder (ADHD), but whether the effective connectivity of the putamen is atypical in ADHD remains unclear. Investigating this abnormality contributes to describing the neural circuit of ADHD at the level of macrostructural organization. @*Methods@#Data were acquired from thirty-two boys with ADHD and fifty-two matched typically developing controls (TDC) from Peking University (Peking) dataset deposited at the Neuroimaging Informatics Tools and Resources Clearinghouse (NITRC) platform. We examined the effective connectivity of the putamen using Granger causality analysis (GCA) and then determined whether these connections could differentiate ADHD from TDC. @*Results@#Compared with TDC, the ADHD group showed decreased effective connectivity from the left ventral rostral putamen (VRP) to left calcarine (CAL), right medial part of the superior frontal gyrus, left orbital part of superior frontal gyrus and left middle occipital gyrus (MOG). Increased effective connectivity from the left inferior occipital gyrus and right lingual gyrus to left VRP was also found in ADHD. The result of the classification accuracy showed that 72.3% of participants were correctly classified using support vector machine. Moreover, GCA values from the left VRP to left CAL and left MOG were significantly correlated with hyper/impulsive scores of patients with ADHD. @*Conclusion@#The findings may help extend our understanding of the ADHD-related neural loops.
ABSTRACT
BACKGROUND@#As one of the most common endocrinal disorders for women at childbearing age, the diagnostic criteria of polycystic ovary syndrome (PCOS) have been defined differently among different international health organizations. Phenotypic heterogeneity of PCOS also brings about difficulties for its diagnosis and management assessment. Therefore, more efficient biomarkers representing the progression of PCOS are expected to be integrated into the monitoring of management process using metabolomic approaches.@*METHODS@#In this prospective randomized controlled trial, 117 PCOS patients were enrolled from December 2016 to September 2017. Classical diagnostic parameters, blood glucose, and metabolome were measured in these patients before and at 2 months and 3 months of different medical interventions. The receiver operating characteristic (ROC) curves were built based on multivariate statistical analysis using data at baseline and 3 months' management, and combinational biomarkers with appreciable sensitivity and specificity were selected, which then validated with data collected at 2 months.@*RESULTS@#A set of metabolites including glutamic acid, aspartic acid, 1-methylnicotinamide, acetylcarnitine, glycerophosphocholine, and oleamide were filtered out with high performance in representing the improvement through 3-month management of PCOS with high sensitivity and specificity in ROC analysis and validation with other two groups showed an appreciable area under the curve over 0.96.@*CONCLUSIONS@#The six metabolites were representative of the remission of PCOS through medical intervention, making them a set of potential biomarkers for assessing the outcome of PCOS management.@*TRIAL REGISTRATION@#ClinicalTrials.gov, NCT03264638.

Objective: To explore the effect of perioperative chemotherapy on the prognosis of gastric cancer patients under real-world condition. Methods: A retrospective cohort study was carried out. Real world data of gastric cancer patients receiving perioperative chemotherapy and surgery + adjuvant chemotherapy in 33 domestic hospitals from January 1, 2014 to January 31, 2016 were collected. Inclusion criteria: (1) gastric adenocarcinoma was confirmed by histopathology, and clinical stage was cT2-4aN0-3M0 (AJCC 8th edition); (2) D2 radical gastric cancer surgery was performed; (3) at least one cycle of neoadjuvant chemotherapy (NAC) was completed; (4) at least 4 cycles of adjuvant chemotherapy (AC) [SOX (S-1+oxaliplatin) or CapeOX (capecitabine + oxaliplatin)] were completed. Exclusion criteria: (1) complicated with other malignant tumors; (2) radiotherapy received; (3) patients with incomplete data. The enrolled patients who received neoadjuvant chemotherapy and adjuvant chemotherapy were included in the perioperative chemotherapy group, and those who received only postoperative adjuvant chemotherapy were included in the surgery + adjuvant chemotherapy group. Propensity score matching (PSM) method was used to control selection bias. The primary outcome were overall survival (OS) and progression-free survival (PFS) after PSM. OS was defined as the time from the first neoadjuvant chemotherapy (operation + adjuvant chemotherapy group: from the date of operation) to the last effective follow-up or death. PFS was defined as the time from the first neoadjuvant chemotherapy (operation + adjuvant chemotherapy group: from the date of operation) to the first imaging diagnosis of tumor progression or death. The Kaplan-Meier method was used to estimate the survival rate, and the Cox proportional hazards model was used to evaluate the independent effect of perioperative chemo therapy on OS and PFS. Results: 2 045 cases were included, including 1 293 cases in the surgery+adjuvant chemotherapy group and 752 cases in the perioperative chemotherapy group. After PSM, 492 pairs were included in the analysis. There were no statistically significant differences in gender, age, body mass index, tumor stage before treatment, and tumor location between the two groups (all P>0.05). Compared with the surgery + adjuvant chemotherapy group, patients in the perioperative chemotherapy group had higher proportion of total gastrectomy (χ(2)=40.526, P<0.001), smaller maximum tumor diameter (t=3.969, P<0.001), less number of metastatic lymph nodes (t=1.343, P<0.001), lower ratio of vessel invasion (χ(2)=11.897, P=0.001) and nerve invasion (χ(2)=12.338, P<0.001). In the perioperative chemotherapy group and surgery + adjuvant chemotherapy group, 24 cases (4.9%) and 17 cases (3.4%) developed postoperative complications, respectively, and no significant difference was found between two groups (χ(2)=0.815, P=0.367). The median OS of the perioperative chemotherapy group was longer than that of the surgery + adjuvant chemotherapy group (65 months vs. 45 months, HR: 0.74, 95% CI: 0.62-0.89, P=0.001); the median PFS of the perioperative chemotherapy group was also longer than that of the surgery+adjuvant chemotherapy group (56 months vs. 36 months, HR=0.72, 95% CI:0.61-0.85, P<0.001). The forest plot results of subgroup analysis showed that both men and women could benefit from perioperative chemotherapy (all P<0.05); patients over 45 years of age (P<0.05) and with normal body mass (P<0.01) could benefit significantly; patients with cTNM stage II and III presented a trend of benefit or could benefit significantly (P<0.05); patients with signet ring cell carcinoma benefited little (P>0.05); tumors in the gastric body and gastric antrum benefited more significantly (P<0.05). Conclusion: Perioperative chemotherapy can improve the prognosis of gastric cancer patients.

Objective:To investigate the clinical efficacy of neoadjuvant chemo-hormonal therapy(NCHT)followed by radical prostatectomy(RP) plus extended pelvic lymphadenectomy for very-high-risk locally advanced prostate cancer.Methods:The data of 327 cases of very-high-risk locally advanced prostate cancer treated in Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine, The Second Hospital of Tianjin Medical University, and The Third Affiliated Hospital of Sun Yat-sen University from December 2014 to July 2019 were retrospectively analyzed. Patients were divided into two groups according to treatment regimens: the RP group (direct RP + extended pelvic lymphadenectomy 4-6 weeks after the biopsy of prostate) and the NCHT group (4-6 cycles of NCHT prior to RP). There were 171 cases in RP group and 156 cases in NCHT group, respectively. In the RP group, the median age was 67 (ranging 44-83)years. The median PSA at diagnosis was 27.24 (ranging 4.55-207.00) ng/ml. Patients’numbers of clinical T 2, T 3a, T 3b, T 4 stage were 13, 85, 57, 16, respectively, and clinical N 1, N 0 stage were 33 and 138, respectively. Patients’numbers of ISUP grade groups of 1, 2, 3, 4, 5 were 5, 35, 41, 51, 39, respectively. In the NCHT group, The median age was 67 years, ranging 46-78 years. The median PSA at diagnosis was 72.09(ranging 4.08-722.95)ng/ml. Patients’ numbers of clinical T 2, T 3a, T 3b, T 4 stage were 11, 47, 58, 40, respectively, and clinical N 1, N 0stage were 76 and 80, respectively. Patients’numbers of ISUP grade groups of 1, 2, 3, 4, 5 were 1, 11, 33, 43, 68, respectively. At baseline, the NCHT group showed higher PSA, higher ISUP grade, and more advanced clinical stage at diagnosis( P<0.05). The PSA, pathological down-staging rate, and positive surgical margin rate as well as the biochemical recurrence free survival(bRFS)were compared between the two groups. Results:After radical prostatectomy, compared with the RP group, the NCHT group had a higher proportion of patients achieving PSA<0.2 ng/ml at 6-week postoperative follow-up ( P<0.001), a higher pathologic tumor stage down-staging rate ( P<0.001), a higher ISUP down-grading rate ( P<0.001), and a lower positive surgical margins rate ( P<0.001). In addition, 10.9% of the NCHT group achieved pT 0 or minimal residual disease in postoperative pathology exams. Eighty-three patients (48.5%) in the RP group and 125 patients (80.1%) in the NCHT group achieved undetectable PSA after surgery and entered further analysis for bRFS, which showed NCHT group had significantly longer bRFS (19.46 months vs. 6.35 months). NCHT significantly reduced the risk for biochemical recurrence in locally advanced prostate cancer patients( HR=0.278, 95% CI 0.198-0.390, P<0.001). Such a reduce in risk for biochemical recurrence was seen in all subgroups( P<0.001). Conclusions:NCHT might improve surgical outcomes as well as bRFS in very-high-risk locally advanced prostate cancer patients.
ABSTRACT
Objective:To discover the clinical features of nocturnal enuresis (NE) in adults and to detect factors that correlated with the symptom severity.Methods:This cross-sectional study recruited NE subjects from September 2017 through December 2020. All patients had experienced enuresis at least once per week and with a symptom duration of 3 months or longer. Followed by documentation of history and medical records, three-day bladder diary was adopted to assess their voiding pattern, and urodynamic parameters were obtained to evaluate lower urinary tract function.Results:A total of 106 NE patients (43 male and 63 female) were identified. There is no statistical difference regarding the average age (men: 57.8±15.6 vs. women: 56.1±14.0, P>0.05) and BMI (men: 23.9±3.4 vs. women: 23.3±4.3, P>0.05) between men and women. Comorbidities are extremely common in NE patients (n=85, 80.2%), with the incidence rate higher in men compared to women [88.4% (38/43)vs. 74.6% (47/63), P<0.05]. Hypertension (n=58, 54.7%), hyperlipemia (n=41, 38.7%), diabetes mellitus (n=38, 35.8%), coronary heart disease (n=22, 20.8%) were the most frequently reported conditions. On bladder diaries, subjects were frequently manifested nocturnal polyuria (NP, 47/106, 44.3%), reduced nocturnal bladder capacity (NBC, 74/106, 69.8%), or combination of both(33/106, 31.3%). Urodynamic studies suggested that the incidence of reduce bladder compliance, detrusor overactivity (DO), stress incontinence, bladder outlet obstruction(BOO), detrusor underactivity(DU)and detrusor hyperreflexia with impaired contractility(DHIC)was 27.4%(29/106), 39.6%(42/106), 17.9%(19/106), 9.4%(10/106), 25.5%(27/106)and 15.1%(16/106), respectively. Women were more likely to suffer from stress urinary incontinence [2.3%(1/43) men vs. 28.6% (18/63) women, P<0.01], while men were prone to have bladder outlet obstruction [ 23.3%(10/43) men vs. 0 women, P<0.01]. Correlation analysis demonstrated that obesity( r=0.63, P<0.01), systemic comorbidities( r=0.40, P<0.01), presence of NP( r=0.50, P<0.01) and NP+ NBC( r=0.47, P<0.01), post-void residual( r=0.53, P<0.01), reduced compliance( r=0.21, P=0.04), DU( r=0.28, P<0.01), stress incontinence( r=0.42, P<0.01)and DHIC ( r=0.35, P<0.01)are positively correlated with NE severity. Whereas, reduced Q max( r=-0.35, P<0.01), low capacity( r=0.21, P=0.03), and reduced bladder sensation( r=-0.21, P=0.03) correlate negatively with NE severity. Conclusions:The presence of NE is not only a sign of bladder dysfunction, but also an implication of obesity, systematic chronic diseases, urine production malfunctioning. Therefore, a thorough history regarding the lower urinary tract function and systemic comorbidities should be taken carefully, so that, an integrated and personalized treatment can be carried out.
ABSTRACT
Colorectal liver metastases (CRLM) is challenging for colorectal cancer therapy, and is also the main cause of death in colorectal cancer patients. In recent years, radiofrequency ablation (RFA) as one of the local treatments for liver tumors, was used in the comprehensive treatment of CRLM in an exploratory manner, expressing its advantages of minimally invasive, feasible, safe, effective and repeatable treatment. This article reviewed the research progress of RFA and RFA combined with other therapy treatments in different stages of CRLM, in order to provide more choices for CRLM comprehensive treatment.
ABSTRACT
Objective@#To assess physical activity level and characteristics in elementary physical education (P.E.) class among different weight status and grades students.@*Methods@#ActiGraphGT3X was used to measure physical activity of 60 students in grade 1, 2, and 4 during three P.E. classes. BMI was calculated according to the student s height and weight in the latest physical fitness test results, and the weight status was divided according to the national Physical Fitness Standards for Students in different grades of elementary schools. Independent sample t test and analysis of variance were used to explore the difference of physical activity.@*Results@#The proportion of moderate to high intensity physical activity (MVPA) in elementary school P.E. class was 21.9% (8.8 min). The proportion of MVPA in P.E. classes and the number of steps in normal weight students were 25.4% and (1 247.0± 326.3 ), respectively, which were significantly higher than those of underweight students, but not significantly different from those of overweight students. The MVPA of male and female PE classes in the second grade (27.0%, 26.4%) was significantly higher than that in the first grade, but there was no significant difference compared with that in the fourth grade ( P >0.05).@*Conclusion@#Moderate to high intensity physical activity is low in P.E. class in elementary school. Improving teachers awareness of promoting physical activity in PE class will benefit the MVPA in students.

ABSTRACT
Objective@#The connectivity alterations in the putamen were found in revealing the neural correlates of attention-deficit/hyperactivity disorder (ADHD), but whether the effective connectivity of the putamen is atypical in ADHD remains unclear. Investigating this abnormality contributes to describing the neural circuit of ADHD at the level of macrostructural organization. @*Methods@#Data were acquired from thirty-two boys with ADHD and fifty-two matched typically developing controls (TDC) from Peking University (Peking) dataset deposited at the Neuroimaging Informatics Tools and Resources Clearinghouse (NITRC) platform. We examined the effective connectivity of the putamen using Granger causality analysis (GCA) and then determined whether these connections could differentiate ADHD from TDC. @*Results@#Compared with TDC, the ADHD group showed decreased effective connectivity from the left ventral rostral putamen (VRP) to left calcarine (CAL), right medial part of the superior frontal gyrus, left orbital part of superior frontal gyrus and left middle occipital gyrus (MOG). Increased effective connectivity from the left inferior occipital gyrus and right lingual gyrus to left VRP was also found in ADHD. The result of the classification accuracy showed that 72.3% of participants were correctly classified using support vector machine. Moreover, GCA values from the left VRP to left CAL and left MOG were significantly correlated with hyper/impulsive scores of patients with ADHD. @*Conclusion@#The findings may help extend our understanding of the ADHD-related neural loops.

ABSTRACT
Prostate cancer is the second most common tumor in men worldwide, and high-risk and locally advanced prostate cancer are life threatening for patients. With the successful application of neoadjuvant therapy in more and more solid tumors, it’s application in prostate tumors has also been gradually started. Among these studies, neoadjuvant hormonal therapy and neoadjuvant hormonal therapy combined with chemotherapy are currently the most widely used. Although neoadjuvant hormonal therapy has been shown effective in reducing the positive rate of resection margins, it cannot improve the long-term survival of patients. Neoadjuvant hormonal therapy combined with chemotherapy may prolong the non-biochemical recurrence time of high-risk locally advanced patients, but whether patients can ultimately achieve survival benefits still needs to be further clarified in prospective randomized controlled studies.
