Abstract
Objective: To establish a predictive model for upper urinary tract damage in children with neurogenic bladder and verify its efficacy. Methods: From January 2011 to December 2021, 143 children with NB in the Children's Hospital of Chongqing Medical University and 84 children with NB in the First Affiliated Hospital of Zhengzhou University were selected as the research objects. The former is set as the training set and the latter is set as the validation set, and the general parameters of the two are compared. The independent risk factors of upper urinary tract damage in children with NB were screened out by Lasso regression, and multivariate logistic regression analysis and a nomogram prediction model was established. The models were validated internally and externally on the training set and validation set, respectively, and the area under the receiver operating curve (ROC) was used to verify the accuracy of the model. Results: A total of 227 children with NB were included in this study, including 121 males and 106 females, aged (10.2±3.8) years. There was no significant difference in other parameters except age between the training set and validation set (all P>0.05); Lasso regression and multivariate logistic regression analysis showed that detrusor leakage point pressure (DLPP) ≥ 40 cmH2O (OR=4.76, 95%CI: 2.01-11.26, 1 cmH2O=0.098 kPa), overactive bladder (OAB) (OR=3.08, 95%CI: 1.34-7.04), bladder compliance (BC)<20 ml/cm H2O (OR=3.65, 95%CI: 1.41-9.47), history of previous urinary tract infection (OR=2.73, 95%CI: 1.09-6.81), and abdominal pressure/other voiding patterns (OR=2.86, 95%CI: 1.20-6.82) were risk factors for upper urinary tract damage in children with NB (all P<0.05). The above parameters were used to establish a nomogram model of upper urinary tract damage in children with NB. The internal and external validation results show that the AUC values for the training and validation sets were 0.84 (95%CI: 0.77-0.91) and 0.86 (95%CI: 0.79-0.94), respectively. Conclusion: The prediction model of upper urinary tract damage in children with NB constructed in this study has high discrimination, accuracy and clinical applicability, which can help clinicians identify high-risk patients and make individualized treatment design for these patients.

Abstract
Objective: To compare the effects of 3 treatment strategies (emergent surgery, self-expanding metallic stents, self-expanding metallic stents plus neoadjuvant chemotherapy) on postoperative anal function and quality of life in patients with complete obstructive left hemicolon cancer. Methods: A retrospective cohort study was conducted. Clinical data of patients with complete obstructive left hemicolon cancer admitted to General Surgery Department of Beijing Chaoyang Hospital between January 2017 and October 2019 were retrospectively collected. Patient inclusion criteria: (1) complete obstructive left hemicolon cancer was confirmed through clinical manifestation and abdominal computed tomography; (2) adenocarcinoma was confirmed by postoperative pathology; (3) emergent radical resection of primary tumor was performed with temporary stoma, or radical resection of primary tumor and primary anastomosis was performed without stoma, 7 to 14 days after completion of insertion of self-expanding metallic stents. Patients who did not receive stoma reversion after emergent operation were excluded. According to different therapies, patients were divided into three groups: emergent surgery (ES) group, self-expanding metallic stents (SEMS) group and self-expanding metallic stents plus neoadjuvant chemotherapy (SEMS+NAC) group. Wexner score for incotinence (higher score indicates the worse anal function), Vaizey score (>10 indicates fecal incontinence) and low anterior resection syndrome (LARS) scale (higher score indicates the worse anal function) were applied to evaluate anal function of patients among groups at postoperative 1-, 6- and 12-month. EORTC QLQ-C30 questionnaire was used to assess the quality of life. Risk factors of decreased anal function were identified by logistic regression analysis. Results: A total of 72 patients were enrolled, including 27 (37.5%) patients in ES group, 23 (31.9%) in SEMS group and 22 (30.6%) in SEME+NAC group. The baseline characteristics including age, gender, tumor location, comorbidities, total blood loss, operation time and postoperative complications, were comparable among groups, except that the proportion of laparoscopic surgery was significantly lower in ES group (4/27, 14.9%) than that in SEMS (15/23, 65.2%) and SEMS+NAC group (16/22, 72.7%) with significant difference (P<0.001). The follow-up ended up to October 2020, and the overall follow-up rate was 79.2% (57/72). No significant differences existed in the Wexner score of patients among groups at postoperative 1-, 6- and 12-month (all P>0.05). The Vaizey scores at postoperative 1-month in ES, SEMS and SEMS+NAC group were 7 (0-17), 3 (0-7) and 4 (0-8) respectively with significant difference (H=18.415, P=0.001), and the scores in SEMS and SEMS+NAC groups were significantly lower than that in ES group (both P<0.05), while no significant difference existed between SEMS and SEMS+NAC group (P>0.05). Vaizey scores at postoperative 6- and 12-month among 3 groups were not significantly different (both P>0.05). The LARS scores at postoperative 1-month in ES, SEMS and SEMS+NAC groups were 20 (0-37), 15 (0-24) and 16 (0-28) respectively with significant difference (H=3.660, P=0.036), and the scores in SEMS and SEMS+NAC groups were significantly lower than that in ES group (both P<0.05), while no significant difference existed between SEMS and SEMS+NAC groups (P>0.05). LARS scores at postoperative 6- and 12-month among 3 groups were not significantly different (both P>0.05). The QLQ-C30 score revealed that the social function of patients in SEMS group and SEMS+NAC group was significantly better than that in ES group (both P<0.05), while no significant difference existed between SEMS and SEMS+NAC group (P>0.05). The logistic regression analysis revealed that only ES was an independent risk factor of decreased anal function (OR=2.264, 95% CI: 1.098-4.667, P=0.027). Conclusion: Compared to ES, SEMS may improve quality of life and short-term anal function of patients with complete obstructive left hemicolon cancer.

Abstract
Objective: To compare the short-term efficacy and perioperative safety of neoadjuvant chemoradiotherapy (nCRT) with total neoadjuvant treatment (TNT) in patients with locally advanced rectal cancer (LARC). Methods: A retrospective cohort analysis was carried out. Inclusion criteria: (1) rectal adenocarcinoma confirmed by pathology with a distance from tumor inferior border to anal verge within 12 cm; (2) clinical stage cT3-4N0 or cT1-4N1-2 diagnosed by magnetic resonance imaging (MRI) or endorectal ultrasonography; (3) a single rectal tumor confirmed by colonoscopy; (4) patients suitable for chemoradiotherapy; (5) no previous history of other tumors. Exclusion criteria: (1)patients with previous rectal cancer surgery and local recurrence; (2) those who did not complete nCRT course; (3) those with distant metastases; (4) those with defective clinicopathological data. According to the above criteria, a total of 134 LARC patients at the Department of General Surgery of Beijing Chaoyang Hospital from January 2016 to January 2019 were enrolled, including 82 males and 52 females, with a male-female ratio of 1.58∶1.00 and mean age of (59.6±11.2) (26-81) years. Based on neoadjuvant regimen, patients were divided into nCRT group (n=55) and TNT group (n=79). There were no statistically significant differences in baseline data, such as age, sex, distance from tumor to anal verge, Eastern Cooperative Oncology Group (ECOG) performance status and clinical TNM stage, between the two groups (all P>0.05). All the patients received pelvic intensity-modulated radiotherapy (IMRT) with a total dose of 50.4 Gy in 28 fractions. Patients in nCRT group received oral capecitabine chemotherapy during radiotherapy and underwent surgery 6-8 weeks after chemoradiation. Patients in TNT group received one cycle of induction CapeOX (oxaliplatin and capecitabine) and concurrent chemoradiotherapy, then underwent a radical surgery two weeks after completion of consolidation chemotherapy. The efficacy of neoadjuvant therapy, adverse events of chemoradiotherapy and perioperative safety were compared between the two groups. Results: Patients of two groups completed the course of neoadjuvant therapy. There were no statistically significant differences between nCRT group and TNT group in the incidence of adverse events in neutropenia [7.3% (4/55) vs. 10.1% (8/79)], anemia [3.6% (2/55) vs. 3.8% (3/79)], thrombocytopenia [5.5% (3/55) vs. 7.6% (6/79)], gastrointestinal dysfunction [3.6% (2/55) vs. 6.3% (5/79)] and radiation enteritis [9.1% (5/55) vs. 8.9% (7/79)] (all P>0.05). One hundred and thirty patients completed TME surgery, including 54 patients in nCRT group and 76 patients in the TNT group. Compared with the nCRT group, the proportion of abdominoperineal resection (APR) was higher in the TNT group [31.6% (25/76) vs. 13.0% (7/54), χ(2)=9.382, P=0.009]. No statistically significant differences in morbidity of postoperative complication, operation time, intraoperative blood loss and postoperative hospital stay between the two groups were found (all P>0.05). The distal and circumferential margins were negative in all the patients. Seventeen patients in the TNT group 22.4% (17/76) got pathologic complete response (pCR), which was significantly higher than 7.4% (4/54) in nCRT group (χ(2)=5.217, P=0.022). There were no statistically significant differences in ypTNM classification, perineural invasion and venous invasion between the two groups (all P>0.05). Conclusion: The pCR of TNT is higher than that of nCRT without increasing the incidence of toxicity and complications of radiotherapy and chemotherapy for patients with locally advanced rectal cancer.

Abstract
Insulin-like factor 3 (INSL3) regulates testicular descent during fetal life, and Insl3 gene inactivation results in cryptorchidism. Little is known, however, about whether the plasticizer diethylhexyl phthalate (DEHP), a contaminant found widely in the environment, influences INSL3 expression. In this study, primary cultures of Leydig cells from mouse embryos were treated in vitro with DEHP. We also treated pregnant mice with DEHP from gestation day 12 to postnatal day 3 in order to study the effect of DEHP in vivo. INSL3 mRNA expression levels in primary Leydig cell cultures and in the testes of newborn mice were significantly lower following DEHP treatment. DEHP also caused detrimental morphological changes in both primary cultures of Leydig cells and the testes of newborn mice. These results suggest that the downregulation of INSL3 mRNA by DEHP might cause abnormalities of gubernacular development, which might be one of the mechanisms for development of cryptorchidism.

Abstract
Based on the previous studies on numerical taxonomy and SDS-PAGE of whole-cell protein, the rhizobia strains isolated from Indigofera sp. in loess plateau area of North-west China constituted a new cluster, the 16S rDNA sequence of representative strain SHL042 was tested, and the phylogenetic tree was produced. In this tree, the strain SHL042, R. tropici A, R. tropici B, R. leguminosarum, R. etli, R. hananesis, R. mongolense and R. gallicum constituted a branch of phylogenetic. Within this branch, the similarity values of 16S rDNA sequences were 95.4%, 95.5%, 96.3%, 95.8%, 96.3%, 97.9% and 97.7% respectively. The values were more than 95%. This indicated that these species should belong to the same genus. The values of DNA homology in the new cluster were all more than 80%, but the values between SHL042 and the strains of these species were less than 50%. Thus, the strain SH714 represented a new rhizobia species.
