Objective:To establish an automatic segmentation network based on different receptive fields for gross target volume (GTV) and organs at risk in patients with nasopharyngeal carcinoma.Methods:Radiotherapy data of 100 cases of nasopharyngeal carcinoma including CT images and GTV and organs at risk delineated by the physicians were collected. Ninety plans were randomly selected as the training dataset, and the other 10 plans as the validation dataset. Firstly, the images were subject to three data augmentation methods including center cropping, vertical flipping and rotation (-30°to 30°), and then input into MA_net networks proposed in this study for training. The model performance of networks was assessed by the number of network parameters (NP), floating-point number (FPN), the running memory (RM) and Dice index (DI), and eventually compared with DeeplabV3+ , PSP_net, UNet+ + and U_Net networks.Results:When the input image was in the size of 240×240, MA_net had a NP of 23.20%, 20.10%, 25.55% and 27.11% of these 4 networks, 50.02%, 19.86%, 6.37% and 13.44% for the FPN, 40.63%, 23.60%, 11.58% and 14.99% for the RM, respectively. For the DI of GTV, MA_net was 1.16%, 2.28%, 1.27% and 3.59% higher than these 4 networks. For the average DI of GTV and OAR, MA_net was 0.16%, 1.37%, 0.30% and 0.97% higher than these 4 networks.Conclusion:Compared with those four networks, the proposed MA_net network has slightly higher Dice index with fewer parameters, lower FPN and smaller RM.

Objective Controversies exist as to the influences of the characteristics of lymph node metastasis ( LNM) on the prognosis of low-grade endometrial carcinoma ( LGEC) .The aim of this study was to investigate the risk factors of LNM and their im-pact on the prognosis of LGEC. Methods This study included 218 LGEC patients treated by retroperitoneal lymph node dissection. We analyzed the pathologic characteristics of LNM and its relationship with the survival rate of the patients. Results LNM was ob-served in 37 of the 218 patients (16.97%), including 20 cases of pelvic (54.05%), 6 cases of para-aortic (16.22%), and 11 ca-ses of both pelvic and para-aortic ( 29.73%) LNM.Independent risk factors of LNM included deep myometrial infiltration ( OR:5.21, 95%CI:2.77-9.81), cervical stromal involvement (OR:3.15, 95% CI:1.12-8.35), lymphovascular invasion (OR:1.15, 95%CI:1.02-1.30), and abnormally high serum CA125 (OR:3.46, 95%CI:1.56-7.67) (P<0.05).There were sig-nificant differences in the 3-year survival rate between the patients with LNM and those without LNM (83.8%vs 95.0%, P<0.05) as well as in the 3-year tumor-free survival rate (73.0% vs 90.1%, P<0.05). Conclusion Deep myometrial infiltration, cervical stromal involvement, lymphovascular invasion, and abnormally high serum CA125 are the risk factors of LNM in LGEC patients, and LNM affects the prognosis of the LGEC patients.

Objective: To explore the clinical characteristics, treatment strategy and prognosis of adenoid cystic carcinoma of the head and neck (ACCHN). Methods: A retrospective analysis of the clinical and follow-up treatment of 79 patients with ACCHN from June 2008 to July 2017 was conducted in the Cancer Hospital of Zhengzhou University.

The clinical manifestations of ACC were related to the locations of primary tumor.The mean size of the tumor was 2.6 cm (range from 1.5 to 7.7 cm). 50 of 79 patients with a definitive pathological diagnosis received surgical resection. 59 cases received chemotherapy and 62 cases received radiotherapy. With a median follow-up of 55 months, the 5-year, 10-year survival rate of these patients were 69.6% and 54.4%, respectively. Conclusions ACCHN is an uncommon neoplasm with the characteristics of epithelial nerve growth, being inclined to distant metastasis, and high early misdiagnosis rate. The clinical manifestation, imaging and pathological result are need to be combined together to diagnose ACCHN.

Objective: To analyze the clinical efficacy of thalidomide combined with TP regimen (taxol+cisplatin) in treatment of advanced gastric cancer. Methods: A total of 60 patients with advanced gastric cancer in the Affiliated Cancer Hospital of Zhengzhou University from February 2016 to March 2018 were enrolled. The patients were divided into two groups by using random number table method: the observation group (32 cases) taking thalidomide, oral administration 100 mg based on TP regimen before going to bed; the control group (28 cases) taking TP regimen chemotherapy only. Both groups received 75 mg/m² doses of cisplatin, intravenous infusion, 25 mg/m² per day, for 3 d. Paclitaxel dose was 150 mg/m², intravenous infusion for 1 day, 3-week was one course, and the efficacy was evaluated after at least 2 course of treatment. Results: The incidence of gastrointestinal adverse reactions including nausea and vomiting was 21.8% (7/32) in the observation group, and was 64.3% (18/28) in the control group, and the difference was statistically significant (χ ² = 11.051, P = 0.001), but there were no statistically significant differences in the incidence of morning faint, constipation, bone marrow suppression, liver and kidney injury and other adverse reactions between the two groups (all P > 0.05). The effective rates in the observation group and the control group were 43.8% (14/32) and 39.3% (11/28), respectively, and the disease control rates in the observation group and the control group were 84.4% (27/32) and 78.6% (22/28), respectively. There were no significant differences in the effective rates and the disease control rates between the two groups (χ ² = 0.122, P = 0.726; χ² = 0.336, P = 0.562). The improvement and significant improvement rate of sleeping quality, pain, Eastern Cooperative Oncology Group (ECOG) score was 71.9% (23/32), 53.1% (17/32), 56.2% (18/32), respectively in the observation group, and 17.9% (5/28), 14.3% (4/28), 21.4% (6/28), respectively in the control group, and the difference between the two groups was statistically significant (all P < 0.05). Conclusions Thalidomide combined with TP regimen in treatment of advanced gastric cancer patients can improve the efficacy of chemotherapy and the quality of life. It also has a good tolerance to side effects.

The biosynthesis and maturation of proteins are primarily regulated by the endoplasmic reticulum in its physiological state. Thus, the disruption of physiological homeostasis initiates the buildup of unfolded and misfolded proteins in the endoplasmic reticulum, resulting in endoplasmic reticulum stress (ERS) and unfolded protein response (UPR). One of the important pathways by which UPR maintains intracellular homeostasis under ERS is activating protein kinase R-like endoplasmic reticulum kinase (PERK). The activation of the PERK pathway stimulates eukaryotic translation initiation factor 2 subunit-α (eIF2α) phosphorylation and the selective translation of active transcription factor 4 (ATF4), and PERK induces cell apoptosis by directly binding to the promoter of pro-apoptotic transcription factor C/EBP homologous protein (CHOP). This signaling pathway is also one of the important mechanisms by which UPR participates in the regulation of hematological malignancies and immune cells in a tumor microenvironment. This article provides an overview of advancements in research into the PERK-eIF2α-ATF4-CHOP signaling pathway in hematological malignancies and the potential therapeutic benefits of targeting this signaling pathway.

Course paper grading often involves subjective factors. Teachers may introduce biases into the grading due to their preferences for certain topics, resulting in inaccurate grading results that fail to reflect the true abilities of students. Taking the grading results of the "Clinical Pharmacology" course as an example, this article investigates the analytical method for detecting topic bias in the course paper grading. A comparative analysis was performed on the differences in the scores between different topics graded by the same teacher and between the same topic graded by different teachers by calculating the vertical bias factor and the horizontal bias factor, and a scientific and feasible analytical method was established. This method can help teachers quickly discover biases in their course paper grading, thereby making the grading more objective and accurate.

Objective:To investigate the prognostic value of using preoperative serum albumin-related biomarkers in gallbladder carcinoma (GBC) patients after resection.Methods:The clinical data of patients who underwent curative-intent resection for GBC at the Department of Hepatobiliary Surgery of the First Affiliated Hospital of Xi’an Jiaotong University from January 2011 to December 2020 were retrospectively analyzed. Of 427 patients who were included in this study, there were 131 males and 296 females, aged (61.75±10.69) years old, range 30 to 87 years old. The 427 patients were divided into the training set ( n=300) and the testing set ( n=127). The training set was used to develop the nomogram model, and the testing set was used to evaluate its predictive ability. The X-Tile software was used to determine the best cut-off values for prognostic nutritional index (PNI), platelet to albumin ratio (PAR), fibrinogen to albumin ratio (FAR), and albumin to γ-glutamyl transpeptidase ratio (AGR). Based on the independent risk factors screened by the Cox proportional hazards regression model, the nomogram survival prediction model was developed by the rms installation package of the R software. The predictive ability of the nomogram was assessed by C-index and calibration curve. Results:The best cut-off values of PNI, PAR, FAR, and AGR were determined to be 44.0, 6.25×10 9/g, 0.08, and 2.03 g/U, respectively. FAR was better than PNI, PAR and AGR in predicting prognosis of patients after radical resection of GBC. Multivariate analysis showed that FAR>0.08 ( HR=2.124, 95% CI: 1.424-3.168), CEA>5.0 ng/ml ( HR=1.577, 95% CI: 1.047-2.375), CA-125>35.0 U/ml ( HR=1.454, 95% CI: 1.031-2.179), N1-2 stage ( HR=2.074, 95% CI: 1.420-3.029), major vascular invasion ( HR=3.292, 95% CI: 1.640-6.608), perineural infiltration ( HR=1.781, 95% CI: 1.045-3.034) and poor tumor differentiation ( HR=6.100, 95% CI: 2.753-13.515) were independent risk factors affecting prognosis of GBC after radical resection ( P<0.05). The C-index of the nomogram model was 0.790 (95% CI: 0.779-0.801) and 0.771 (95% CI: 0.754-0.788) in the training set and the testing set, respectively. Conclusion:Preoperative FAR had a good predictive ability for overall survival in patients with gallbladder carcinoma after radical resection, and it could be used for prognostic evaluation.
