A Multi-Label Text Classifier at Publication Level Based on "PubMedBERT + TextRNN" for Cancer Literature.

There is a rapid growth in the volume of data in the cancer field and fine-grained classification is in high demand especially for interdisciplinary and collaborative research. There is thus a need to establish a multi-label classifier with higher resolution to reduce the burden of screening articles for clinical relevance. This research trains a multi-label classifier with scalability for classifying literature on cancer research directly at the publication level. Firstly, a corpus was divided into a training set and a testing set at a ratio of 7:3. Secondly, we compared the performance of classifiers developed by "PubMedBERT + TextRNN" and "BioBERT + TextRNN" with ICRP CT. Finally, the classifier was obtained based on the optimal combination "PubMedBERT + TextRNN", with P= 0.952014, R=0.936696, F1=0.931664. The quantitative comparisons demonstrate that the resulting classifier is fit for high-resolution classification of cancer literature at the publication level to support accurate retrieving and academic statistics.

Expert consensus on the evaluation and management of dysphagia after oral and maxillofacial tumor surgery / 实用口腔医学杂志

Surgical operation is the main treatment of oral and maxillofacial tumors.Dysphagia is a common postoperative complication.Swal-lowing disorder can not only lead to mis-aspiration,malnutrition,aspiration pneumonia and other serious consequences,but also may cause psychological problems and social communication barriers,affecting the quality of life of the patients.At present,there is no systematic evalua-tion and rehabilitation management plan for the problem of swallowing disorder after oral and maxillofacial tumor surgery in China.Combining the characteristics of postoperative swallowing disorder in patients with oral and maxillofacial tumors,summarizing the clinical experience of ex-perts in the field of tumor and rehabilitation,reviewing and summarizing relevant literature at home and abroad,and through joint discussion and modification,a group of national experts reached this consensus including the core contents of the screening of swallowing disorders,the phased assessment of prognosis and complications,and the implementation plan of comprehensive management such as nutrition management,respiratory management,swallowing function recovery,psychology and nursing during rehabilitation treatment,in order to improve the evalua-tion and rehabilitation of swallowing disorder after oral and maxillofacial tumor surgery in clinic.

Mechanism of electroacupuncture on improving corneal inflammation in dia-betic dry eye rats by regulating Toll-like receptor 4-mediated inflammatory signaling pathway / 眼科新进展

Objective To observe the effect of electroacupuncture on corneal Toll-like receptor 4(TLR4)-mediated inflammatory signaling pathway in diabetic dry eye rats and to explore the mechanism of electroacupuncture in the treat-ment of diabetic dry eye.Methods A type 2 diabetic rat model was established in 32 healthy male Sprague-Dawley(SD)rats by intraperitoneal injection of streptozotocin(30 mg·kg-1)for 12 weeks after feeding with high-sugar and high-fat di-et for 4 weeks.Twenty-five successfully modeled diabetic dry eye rats were randomly divided into the model group(non-in-tervention),electroacupuncture group(the"Jingming","Cuanzhu","Sizhukong","Taiyang"and"Tongziliao"acupoints were treated with acupuncture,and then"Cuanzhu"and"Tongzilao"acupoints were treated with electroacupuncture,15 min for each time,once a day),sham acupuncture group(blunt-tip needle pricking was performed at the same acupoints as the electroacupuncture group),and fluorometholone group(1 g·L-1fluorometholone eye drops were used in both eyes at 8 o'clock,13 o'clock,and 18 o'clock,1 drop each time),with 6 rats in each group,lasting for 2 weeks.Another 6 healthy male SD rats were selected as a blank group.Random blood glucose,tear film breakup time(BUT),tear secre-tion,corneal fluorescein staining(FL)score,and corneal touch threshold(CTT)of rats in each group were detected be-fore modeling,after modeling,and after the intervention.Hematoxylin and Eosin(HE)staining was performed to observe the corneal morphologic changes in each group.Immunofluorescence histochemical staining was adopted to detect the cor-neal TLR4-positive expression in each group.The TLR4,phosphorylated nuclear factor-kappa P65(P-NF-KB P65),inter-leukin(IL)-1β,and IL-18 expression levels in the cornea were detected by Western blot.Results After modeling,com-pared with the blank group,BUT,tear secretion and CTT decreased and FL increased in all experimental groups,and the differences were statistically significant(all P＜0.01).After the intervention,compared with the model group,FL de-creased,and BUT,tear secretion and CTT increased in the electroacupuncture group,and the differences were statistically significant(all P＜0.05).Corneal HE staining showed that after the intervention,the corneal surface of rats in the model group and sham acupuncture group was not smooth,and the corneal epithelial cells were thickened and disorganized;the corneal surface of rats in the electroacupuncture group and fluorometholone group was smooth,and the corneal epithelial cells were arranged neatly.After the intervention,compared with the blank group,the corneal TLR4 expression of rats in all other groups was elevated,and the differences were statistically significant(all P＜0.05);compared with the model group,the corneal TLR4 expression of rats in the electroacupuncture group and fluorometholone group was reduced(both P＜0.01).Compared with the blank group,corneal TLR4,P-NF-κBP65,IL-1β and IL-18 protein expressions increased in the model group and sham acupuncture group(all P＜0.05);compared with the model group,these expressions decreased in the electroacupuncture group and the fluorometholone group(all P＜0.05).Conclusion Electroacupuncture can im-prove the ocular surface signs and inhibit the expressions of TLR4,P-NF-κB P65,IL-1 β,and IL-18 in the cornea of type 2 diabetic dry eye rats,and its mechanism of action may be related to the regulation of TLR4-mediated inflammatory signaling pathway,which inhibits ocular surface inflammation in diabetic dry eye rats.

Multivariate Logistic regression analysis showed that senior grades, parental myopia, daily insufficient sleep and outdoor activity, overuse of electronics or computers and no eye exercise were risk factors for poor vision.CONCLUSION: The rate of poor vision among the primary school students was severe, schools should take measures to improve and prevent students' poor vision by increasing outdoor activity time, correcting poor reading and writing posture, and reducing the time spent on electronic products.

Case report: Immunotherapy plus chemotherapy and stereotactic ablative radiotherapy (ICSABR): a novel treatment combination for Epstein-Barr virus-associated lymphoepithelioma-like intrahepatic cholangiocarcinoma.

Epstein-Barr virus-associated lymphoepithelioma-like intrahepatic cholangiocarcinoma (EBVa LEL-ICC) is a rare tumor, characterized by a rich tumor immune microenvironment (TIME). While this tumor is reportedly sensitive to immunotherapy, its response has been inconsistent. This decreased sensitivity was associated with reduced TIME abundance. We report the case of a 53-year-old woman with EBVa LEL-ICC having reduced TIME abundance. The patient presented with a liver lesion, which was detected using ultrasound. Initially, the tumor was sensitive to immunotherapy and chemotherapy (IC), but resistance developed after a short interval. Subsequently, stereotactic ablative radiotherapy (SABR) was added to the patient's treatment, which now consisted of ICSABR. Successful tumor shrinkage was achieved with the combination therapy regimen. Thus, surgery and ICSABR are effective adjuncts to the first-line IC therapy in improving the survival rate of patients with EBVa LEL-ICC. The results of this study support multidisciplinary treatment as a viable treatment strategy for EBVa LEL-ICC.

Clinical and genetic analysis of a very early-onset inflammatory bowel disease type 28 child with atypical clinical manifestation / 中华医学遗传学杂志

OBJECTIVE@#To explore the clinical and genetic characteristics of a very early-onset inflammatory bowel disease (VEO-IBD) type 28 child with atypical clinical manifestations.@*METHODS@#A VEO-IBD type 28 child with atypical clinical manifestations admitted to the Department of Neonatology, Children's Hospital Affiliated to Shandong University on November 5, 2021 was selected as the study subject. Clinical data of the child was collected. Peripheral venous blood samples of the child and his parents were collected for high-throughput sequencing. Candidate variants were verified by Sanger sequencing and bioinformatic analysis.@*RESULTS@#The child, a 50-day-old male, had manifested bronchitis, ulcerative stomatitis, eczema and slightly loose stool. High-throughput sequencing revealed that he has harbored compound heterozygous variants of the IL-10RA gene, namely c.299T>G (p.V100G) and c.301C>T (p.R101W), which were inherited from his father and mother, respectively. Bioinformatic analysis showed that both variants have been recorded in the HGMD database, though the c.299T>G variant has not been included in the gnomAD, 1000 Genomes, ExAC and ESP6500 databases, while the c.301C>T variant has a low population frequency. Both variants were predicted to be deleterious by the online software including SIFT, PolyPhen-2 and Mutation Taster. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), both variants were predicted to be pathogenic (PS3+PM2_Supporting+PP3).@*CONCLUSION@#The c.299T>G and c.301C>T variants of the IL-10RA gene probably underlay the VEO-IBD type 28 in this child. Above finding has expanded the phenotypic spectrum of VEO-IBD type 28 due to variants of the IL-10RA gene and provided a reference for the clinical diagnosis of this disease.

Radical therapy with or without chemotherapy in highly malignant non-metastatic prostate cancer: interim analysis of a prospective non-randomized controlled study / 中华放射肿瘤学杂志

Objective:To compare the efficacy and safety of standard treatment with or without adjuvant chemotherapy in patients with highly malignant non-metastatic prostate cancer.Methods:In this prospective non-randomized controlled study, consecutive non-metastatic prostate cancer patients with pathologically proven Gleason score of 9-10 or Gleason score of 5 admitted to Peking University First Hospital were enrolled. Four to six cycles of chemotherapy using docetaxel ± carboplatin regimen were added or not after standard radical therapy. The primary end point was 5-year event-free survival (EFS), and the secondary end points were distant metastasis-free survival (MFS), overall survival (OS), and treatment-related adverse events. The survival curve was drawn by Kaplan-Meier method. The differences between two groups were analyzed by log-rank test.Results:A total of 176 patients were consecutively enrolled from November 2019 to January 2022 of which 138 patients received only standard radical therapy (control group), and 38 patients received adjuvant chemotherapy after standard radical therapy (chemotherapy group). The median follow-up time was 13.4 (2.0-34.0) months. All patients survived. The 30-month EFS rates in the chemotherapy and control groups were 100% and 85.6%, respectively ( P=0.064). There were no events in the chemotherapy group, while there were 12 cases of events in the control group, including 6 cases of biochemical recurrence and 6 cases of imaging progression. The 30-month MFS rates in two groups were 100% and 91.9%, respectively ( P=0.205). After the 1 vs. 2 propensity score matching, the EFS and MFS rates in two groups were 100% vs. 85.7% ( P=0.056), and 100% vs. 92.2% ( P=0.209), respectively. The incidence rates of grade 2 and above urinary toxicity in the chemotherapy and control groups were 2.6% and 7.2% ( P=0.354), respectively. The incidence rates of grade 2 and above rectal toxicity were 5.3% and 5.1% ( P=0.711), respectively. Grade 3 and above chemotherapy-related toxicity in the chemotherapy group were leukopenia (31.6%), thrombocytopenia (2.6%) and alopecia (13.2%). Conclusion:The addition of adjuvant chemotherapy after standard radical therapy tends to improve the overall EFS of patients with highly malignant prostate cancer, and the adverse effects are tolerable, which should be confirmed by long-term follow-up results.

Risk factors of local recurrence and survival in patients with upper tract urothelial carcinoma after nephroureterectomy with lymph node dissection / 中华泌尿外科杂志

Objective:To evaluate risk factors for local recurrence and prognosis in patients with upper tract urothelial carcinoma (UTUC) after radical nephroureterectomy combined with lymph node dissection (LND).Methods:The data of 237 patients who were diagnosed with UTUC in Peking University First Hospital and received radical nephroureterectomy combined with LND during January 2010 and March 2022 were retrospectively reviewed. Clinicopathologic characteristics and oncological outcomes were compared according to lymph node metastasis. There were 122 males and 115 females. The tumors of 122 cases were located on the left, while 115 cases were on the right. The tumors of 102 cases were in the renal pelvic, 124 cases in the ureter and 11 cases in both sites. The mean age was (65.52±10.14) years old. The overall survival (OS), cancer-specific survival (CSS), local recurrence-free survival (LRFS) of all patients were valued using Kaplan-Meier method, and the survival curves with statistical significance between two groups were analyzed by log-rank test. Univariate and multivariate Cox proportional hazards regressions were performed to identify the independent risk factors for CSS and LRFS.Results:There were 122 males and 115 females. According to the lymph node metastasis, the patients were divided into lymph node negative group ( n=180, 75.9%) and lymph node positive group ( n=57, 24.1%). Lymph node positive group had a higher percentage in renal tumor [57.9%(33/57) vs. 38.1% (69/180)], stage T 3-4 [84.2%(48/57) vs. 32.8%(59/180)], G 3 [91.2%(52/57) vs. 55.6%(100/180)], glandular differentiation [17.5%(10/57) vs. 4.4%(8/180)], sarcomatoid differentiation [22.8%(13/57) vs. 9.4%(17/180)], necrosis [47.4%(27/57) vs. 16.1%(29/180)], lymphovascular invasion [40.4%(23/57) vs. 12.2%(22/180)] and the number of lymph node dissection [ 4(1, 10) vs. 2(1, 5)]. There were significant differences between the two groups ( P<0.05). Of 237 patients, 42 lost of follow up. The median follow-up time was 46(22, 79) months. Among the 195 patients, 52 patients died, and 42 died due to the tumor. Of all patients, 58(29.7%) had local recurrence, 34 had local recurrence alone, and 24 had concurrent distant metastasis. The 5-year OS and CSS were 67.4% and 71.3%, respectively. The 5-year OS and CSS were 70.5% and 75.1% respectively in the lymph node negative group, 57.5% and 59.4% respectively in the lymph node positive group ( P < 0.05). The 3-year LRFS was 68.0% for all the patients. The 3-year LRFS was 75.6% in the lymph node negative group and 44.5% in the lymph node positive group ( P<0.05). Multivariate analysis showed that tumor stage T 3-4( HR =3.924, 95% CI 2.045-7.529, P<0.001) and G 3( HR=2.871, 95% CI 1.193-6.909, P =0.019) were independent risk factors for LRFS. Multivariate analysis showed that age ≥70 years ( HR = 3.578, 95% CI 1.917-6.678, P<0.001) and pathological stage T 3-4 ( HR =2.366, 95% CI 1.278-4.381, P =0.006) were independent risk factors for CSS. Multivariate analysis showed that age ≥70 years ( HR = 3.874, 95% CI 2.190-6.853, P<0.001) and pathological stage T 3-4 ( HR = 2.757, 95% CI 1.565-4.857, P<0.001) were independent risk factors for OS. Conclusions:Patients with high T stage, high grade, as well as glandular differentiation, sarcomatoid differentiation, necrosis, lymphovascular invasion are more likely to have positive lymph node detection. Age ≥70 years and stage T 3-4 were independent risk factors for CSS and OS. Stage T 3-4 and G 3were independent risk factors for LRFS.

Evaluation of platelet/lymphocyte ratio in adult of obstructive sleep apnea syndrome / 中国耳鼻咽喉头颈外科

OBJECTIVE Aimed to explore the correlation between platelet/lymphocyte ratio(PLR)and adult obstructive sleep apnea syndrome(OSAS).METHODS The data of 249 patients with OSAS were retrospectively analyzed.According to apnea-hypopnea index(AHI),the patients were divided into mild,moderate and severe groups.Meanwhile,there were 70 healthy adults who underwent physical examination in West China Fourth Hospital,Sichuan University in the control group.The differences of PLR between OSAS group and control group were compared.Pearson correlation analysis was used to analyze the correlation between PLR and AHI,percentage of sleep time spent below 90％oxygen saturation(TS90％),the lowest oxygen saturation at night(LSaO2)and body mass index(BMI).Logistic regression was used to analyze the independent risk factors of OSAS.RESULTS There was no significant difference in PLR between OSAS group(1 16.91±40.98)and control group(110.04±36.92)(P＞0.05),but the severe group(112.03±39.68)was significant lower than that of moderate group(125.67±47.00)and mild group(131.22±36.64)(P＜0.05),severe group was lower than that in mild group(P＜0.05).In patients with severe OSAS,the BMI,AHI,microarousal index,maximum hypopnea time and TS90％in the obese group were higher than those without obese,the LSaO2 and PLR were significant lower than those without obese(P＜0.05).Pearson correlation analysis showed a negative correlation between PLR and BMI(r=-0.216,P＜0.01),and negatively correlated with AHI and TS90％,but there was no statistically significant difference(P＞0.05),PLR and LSaO2 were positively correlated(r=0.146,P＜0.05).PLR(OR=1.014,P=0.002)and BMI(OR=1.743,P=0.000)were independent predictors of OSAS.CONCLUSION Serum PLR values in OSAS patients tended to decrease with the increase of AHI values,and PLR was lower in obese patients with severe OSAS,and PLR was also an independent risk factor for OSAS.

Advances in diagnosis,prevention and treatment of flexible flatfoot in children / 中国学校卫生

Abstract@#Flexibleis an important classification of flat foot. Flatfoot occurs due to a variety of reasons and causes the medial longitudinal arch to collapse or disappear. However, many children still do not develop a normal foot arch as the grow, and a failure to intervene in a timely manner will greatly harm a child s normal mobility development. Timely detection and intervention are the key to improve the prognosis. There is a lack of uniform quantitative criteria for the diagnosis of flexible flatfoot. Currently, the commonly used diagnostic methods include physical examination, foot printing, plantar pressure test and imaging examination. This article reviews the risk factors, diagnosis, prevention and treatment of Flexible Flatfoot.

Role of soy lecithin combined with soy isoflavone on cerebral blood flow in rats of cognitive impairment and the primary screening of its optimum combination

BACKGROUND/OBJECTIVES@#Soy isoflavone (SIF) and soy lecithin (SL) have beneficial effects on many chronic diseases, including neurodegenerative diseases. Regretfully, there is little evidence to show the combined effects of these soy extractives on the impairment of cognition and abnormal cerebral blood flow (CBF). This study examined the optimal combination dose of SIF + SL to provide evidence for improving CBF and protecting cerebrovascular endothelial cells.MATERIALS/METHODS: In vivo study, SIF50 + SL40, SIF50 + SL80 and SIF50 + SL160 groups were obtained. Morris water maze, laser speckle contrast imaging (LSCI), and hematoxylineosin staining were used to detect learning and memory impairment, CBF, and damage to the cerebrovascular tissue in rat. The 8-hydroxy-2′-deoxyguanosine (8-OHdG) and the oxidized glutathione (GSSG) were detected. The anti-oxidative damage index of superoxide dismutase (SOD) and glutathione (GSH) in the serum of an animal model was also tested. In vitro study, an immortalized mouse brain endothelial cell line (bEND.3 cells) was used to confirm the cerebrovascular endothelial cell protection of SIF + SL. In this study, 50 μM of Gen were used, while the 25, 50, or 100 μM of SL for different incubation times were selected first. The intracellular levels of 8-OHdG, SOD, GSH, and GSSG were also detected in the cells. @*RESULTS@#In vivo study, SIF + SL could increase the target crossing times significantly and shorten the total swimming distance of rats. The CBF in the rats of the SIF50 + SL40 group and SIF50 + SL160 group was enhanced. Pathological changes, such as attenuation of the endothelium in cerebral vessels were much less in the SIF50 + SL40 group and SIF50 + SL160 group. The 8-OHdG was reduced in the SIF50 + SL40 group. The GSSG showed a significant decrease in all SIF + SL pretreatment groups, but the GSH showed an opposite result. SOD was upregulated by SIF + SL pretreatment. Different combinations of Genistein (Gen)+SL, the secondary proof of health benefits found in vivo study, showed they have effective antioxidation and less side reaction on protecting cerebrovascular endothelial cell. SIF50 + SL40 in rats experiment and Gen50 + SL25 in cell test were the optimum joint doses on alleviating cognitive impairment and regulating CBF through protecting cerebrovascular tissue by its antioxidant activity. @*CONCLUSIONS@#SIF+SL could significantly prevent cognitive defect induced by β-Amyloid through regulating CBF. This kind of effect might be attributed to its antioxidant activity on protecting cerebral vessels.

Medical Big Data and Postoperative Nursing of Fracture Patients Based on Cloud Computing.

Based on the standards for wireless sensor system identification, the sensor node identity OID identification and the management object OID identification in the SNMP MIB are merged, and a management object OID identification coding mechanism for the SNMP-based wireless sensor system is proposed to make the node management system only. The identity, attributes, and multiple entities of the target sensor node in the wireless sensor network can be identified and managed by the node management object OID. The source of abnormal medical big data generally uses two models of multidimensional data and sliding window for detection and verification. First, the sliding window can be used to detect abnormalities. The result is that under this condition, the detection rate of medical big data is more than 95%; the effect is very good, but in different dimensions, the detection rate of four-dimensional data is 2.9% higher than that of a single-dimensional one. On the basis of the ZigBee wireless network, the terminal signal transmission of fracture treatment can be realized. On this basis, combined with the actual needs of fracture treatment, it can be built with its wireless module. The wireless network has a certain basic function. The reform of the nursing system was carried out on the basis of the safety and reliability of the nursing system, the efficiency of the nursing system was improved, and timely and safe nursing services were achieved.

Requirements and Thoughts on Ethical Review of Clinical Research Manuscripts in Medical Academic Journals: from the Perspective of Ethics Committee / 中国医学伦理学

There are specific ethical requirements and review principles for submitting papers or reports in medical academic journals. Researchers often consult the ethics committee on the rationality of the ethical requirements of journals at the (to be) submission stage, or ask for assistance in solving the ethical review requirements of journals: applying for ethical review for the clinical research to which submitted papers or research reports. Based on the perspective of hospital ethics committee, this paper discussed the ethical review requirements of academic journals for clinical research papers or reports. Combined with the practice of handling clinical research authors’ demands, the current situation of applying for ethical review, common problems and cases, this paper put forward three suggestions: academic journals should concretize the ethical review requirements of submitted papers or reports; researchers should internalize "ethics first" in their hearts, and conduct research according to laws and regulations; ethics committee should give full play to positive guidance and services, and cooperate with clinical research management departments to strengthen and complete the supervision of clinical research. So as to provide ideas for further standardizing the publication of clinical research papers and reports.

Establishment and practice of the management model of prescription refills for chronic diseases during the COVID-19 epidemic / 西安交通大学学报(医学版)

Combined with the relevant policies promulgated by the state, the paper elaborates three basic modes of prescription refill management for chronic diseases: community model, pharmacy model, and distribution model.
