Purpose: Cancer has become a significant major public health concern, making the discovery of new cancer markers or therapeutic targets exceptionally important. Elevated expression of tumor necrosis factor receptor superfamily member 12A (TNFRSF12A) expression has been observed in certain types of cancer. This project aims to investigate the function of TNFRSF12A in tumors and the underlying mechanisms. Materials and Methods: Various websites were utilized for conducting the bioinformatics analysis. Tumor cell lines with stable knockdown or overexpression of TNFRSF12A were established for cell phenotyping experiments and subcutaneous tumorigenesis in BALB/c mice. RNA-seq was employed to investigate the mechanism of TNFRSF12A. Results: TNFRSF12A was upregulated in the majority of cancers and associated with a poor prognosis. Knockdown TNFRSF12A hindered the colorectal cancer progression, while overexpression facilitated malignancy both in vitro and in vivo. TNFRSF12A overexpression led to increased nuclear factor кB (NF-κB) signaling and significant upregulation of baculoviral IAP repeat containing 3 (BIRC3), a transcription target of the NF-κB member RELA, and it was experimentally confirmed to be a critical downstream factor of TNFRSF12A. Therefore, we speculated the existence of a TNFRSF12A/RELA/BIRC3 regulatory axis in colorectal cancer. Conclusion TNFRSF12A is upregulated in various cancer types and associated with a poor prognosis. In colorectal cancer, elevated TNFRSF12A expression promotes tumor growth, potentially through the TNFRSF12A/RELA/BIRC3 regulatory axis.

BACKGROUND:Dysfunction of macrophage efferocytosis can induce local and systemic inflammatory damage and is associated with a variety of obesity-related metabolic diseases.Moreover,compounds targeting efferocytosis have shown good therapeutic effects. OBJECTIVE:By reviewing the effects of obesity on macrophage efferocytosis,to analyze the key mechanism by which obesity inhibits efferocytosis,to summarize the research progress in compounds targeting efferocytosis to treat obesity-related metabolic diseases,so as to provide new ideas for fully understanding efferocytosis and its relationship with metabolic diseases,aiming to provide new strategies for disease prevention and treatment. METHODS:The English search terms were"efferocytosis,metabolism,obesity,obese,atherosclerosis,non-alcoholic steatohepatitis,neurodegeneration,tumor,osteoarthritis,diabetes,compound,medicine,treatment,"which were used for literature retrieval in PubMed and Web of Science.The Chinese search term was"efferocytosis,"which was used for literature retrieval in CNKI,VIP and WanFang datebases.Ninety-nine papers were finally included in the review analysis after a rigorous screening process. RESULTS AND CONCLUSION:In the process of efferocytosis,the"Find me"and"Eat me"processes involving a large number of apoptotic cell derived factors are mainly regulated by apoptotic cells.The efferocytosis factor involved in cytoskeletal remodeling and digestion are mainly derived from macrophages,which are crucial for efferocytosis activity.These results suggest that the"Find me"and"Eat me"factors mainly reflect the condition of apoptosis,and it is more scientific to select the expression of factors involved in cytoskeletal remodeling and digestion when evaluating the efferocytosis activity of macrophages.Obesity inhibits efferocytosis,and shows an inhibitory effect on most digestive factors,but has a stress-induced activation effect on most"Find me,""Eat me"and cytoskeletal recombination factors,which further indicates the decisive effect of digestive stage on efferocytosis and suggests that it is not reliable for some studies to evaluate the efferocytosis based on the increased expression of"Find me"and"Eat me"factors.Targeting cytokines in the digestive phase may be more effective when discussing future intervention strategies targeting macrophages efferocytosis.The efferocytosis activators of macrophages are effective in the treatment of various metabolic diseases,but the efferocytosis inhibitors in tumor tissue show good anticancer effects,suggesting that the role of efferocytosis should be rationally evaluated according to the characteristics of tissue inflammation.Efferocytosis is a relatively new concept proposed in 2003,with a short research history and complex efferocytosis factors.Current studies on obesity and efferocytosis only involve a tip of the iceberg and most of them are at a superficial level and a large number of scientific experiments are needed to further validate the mechanisms.

Objective To systematically evaluate the prognostic prediction model for chronic heart failure patients in China, and provide reference for the construction, application, and promotion of related prognostic prediction models. Methods A comprehensive search was conducted on the studies related to prognostic prediction model for Chinese patients with chronic heart failure published in The Cochrane Library, PubMed, EMbase, Web of Science, CNKI, VIP, Wanfang, and the China Biological Medicine databases from inception to March 31, 2023. Two researchers strictly followed the inclusion and exclusion criteria to independently screen literature and extract data, and used the prediction model risk of bias assessment tool (PROBAST) to evaluate the quality of the models. Results A total of 25 studies were enrolled, including 123 prognostic prediction models for chronic heart failure patients. The area under the receiver operating characteristic curve (AUC) of the models ranged from 0.690 to 0.959. Twenty-two studies mostly used random splitting and Bootstrap for internal model validation, with an AUC range of 0.620-0.932. Seven studies conducted external validation of the model, with an AUC range of 0.720-0.874. The overall bias risk of all models was high, and the overall applicability was low. The main predictive factors included in the models were the N-terminal pro-brain natriuretic peptide, age, left ventricular ejection fraction, New York Heart Association heart function grading, and body mass index. Conclusion The quality of modeling methodology for predicting the prognosis of chronic heart failure patients in China is poor, and the predictive performance of different models varies greatly. For developed models, external validation and clinical application research should be vigorously carried out. For model development research, it is necessary to comprehensively consider various predictive factors related to disease prognosis before modeling. During modeling, large sample and prospective studies should be conducted strictly in accordance with the PROBAST standard, and the research results should be comprehensively reported using multivariate prediction model reporting guidelines to develop high-quality predictive models with strong scalability.

Metastasis-associated drug resistance accounts for high mortality in ovarian cancer and remains to be a major barrier for effective treatment. In this study, SKOV3/T4, a metastatic subpopulation of ovarian cancer SKOV3 cells, was enriched to explore potential interventions against metastatic-associated drug resistance. Quantitative genomic and functional analyses were performed and found that slug was significantly increased in the SKOV3/T4 subpopulation and contributed to the high resistance of SKOV3/T4. Further studies showed that slug activated c-Met in a ligand-independent manner due to elevated levels of fibronectin and provoked integrin V function, which was confirmed by the significant correlation of slug and p-Met levels in 121 ovarian cancer patient samples. Intriguingly, c-Met inhibitor(s) exhibited greatly enhanced anti-cancer effects in slug-positive ovarian cancer models both and . Additionally, IHC analyses revealed that slug levels were highly correlated with reduced survival of ovarian cancer patients. Taken together, this study not only uncovers the critical roles of slug in drug resistance in ovarian cancer but also highlights a promising therapeutic strategy by targeting the noncanonical activation of c-Met in slug-positive ovarian cancer patients with poor prognosis.

Objective To explore the effects of Barthel index assessment exercise in postoperative grading nursing among total laryngectomy patients. MethodsFrom January 2018 to June 2019, we selected 51 laryngeal carcinoma patients undergoing total laryngectomy in Otolaryngology Head and Neck Surgery at Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School, as subjects by convenience sampling. All of patients were divided into control group (n=24) and observation group (n=27) with the method of random number table. We compared the differences in the levels of grading nursing, compliance of early ambulation after surgery and self-care ability of patients between two groups. ResultsThere were no statistical difference in the levels of grading nursing of patients between two groups after surgery (P＞ 0.05). The compliance of early ambulation of patients after surgery in observation group was better than that in control group with a statistical difference (P＜0.05). The total score and dimension scores of self-care ability of patients in observation group were higher than those in control group one day before discharge with statistical differences (P＜0.05). ConclusionsBarthel index assessment exercise can objectively assess the activities of daily living of total laryngectomy postoperative patients, improve the compliance of early ambulation after surgery and self-care ability of patients.

Objective To investigate the abnormal functional connectivity (FC) between the cores (including sublaterodorsal nucleus (SLD) and ventrolateral periaqueductal gray matter (vlPAG)) and the whole brain in rapid eye movement sleep behavior disorder (RBD) by resting state functional magnetic resonance imaging (rfMRI).Methods A total of 41 subjects recruited in the Department of Neurology,the People's Hospital of Zhengzhou University were enrolled in this study according to international diagnosis criteria,including 20 with idiopathic RBD (iRBD group) and 21 age,sex-matched normal controls (control group).All subjects were examined by Hoehn-Yahr Staging,cognitive tests and rfMRI.Resluts HoehnYahr staging score was 0(0,0) in the iRBD group,which showed no significant difference from that in the control group (0 (0,0),Z =-1.820,P =0.069).The scores of Rey Auditory Verbal Learning Test (AVLT) N1,AVLT N2,Symbol Digital Modalities Test,Rey-Osterrieth Complex Figure Test-Copy were 3.80 ± 1.67,5.10 ± 1.77,33.00(31.25,34.00) and 22.00(20.25,26.00) respectively in the iRBD group,which were significantly lower than that in the control group (4.95 ± 1.28,t =2.482,P =0.017;6.43±1.16,t =2.848,P=0.007;33.00(29.50,35.50),Z=-3.792,P=0.000;35.00(33.00,36.00),Z =-2.351,P =0.019) respectively.The scores of Trail Making Test 1 (86.5 (70.0,100.0))and Trail Making Test 2 (197.0(180.5,211.5)) in the iRBD group were significantly higher than that in the control group (66.0(49.0,91.5),112.0(99.5,173.0) respectively,Z=-2.373,P=0.018;Z =-3.105,P =0.002).Compared with the control group,the FC analysis showed reduced connections from the right SLD to the bilateral cingnlate gyrus (t =-4.173) and bilateral frontal gyrus (t =-2.965(left),-3.662(right)),from the vlPAG to the left precentral-postcentral gyrus(t =3.930),and from the vlPAG to the right frontal gyrus (t =4.141) in the iRBD.There was no statistically significant difference from the left SLD to the whole brain.Conclusion There were abnormal FCs from the SLD and vlPAG to cognitive and motor areas in RBD patients,perhaps leading to clinical RBD symptoms such as cognitive deterioration and movement disorder.

Objective To investigate the abnormal functional connectivity (FC) between the substantia nigra (SN) and the brain motor area in rapid eye movement sleep behavior disorder (RBD) by Unified Parkinson′s Disease Rating Scale (UPDRS), Hoehn-Yahr Scale and resting state functional magnetic resonance imaging (rfMRI).Methods A total of 34 subjects (14 with RBD (RBD group), 12 with Parkinson′s disease (PD group), and 8 age, sex-matched normal controls (control group)) recruited in the Department of Neurology, Henan Provincial People′s Hospital from 2014 to 2015 were enrolled in this study according to international diagnosis criteria.All subjects were examined by UPDRS, Hoehn-Yahr Scale and rfMRI.Results UPDRS scores and Hoehn-Yahr staging were 0.00 (0.00, 3.75) and 0.00 (0.00, 0.50) respectively in the RBD group, which were significantly different from that in the PD group (30.5 (18.75, 33.00) and 1.75 (1.50, 2.50), respectively;Z=-3.782, P<0.05 and Z=-2.963, P<0.05), whereas not significantly different from that in the control group (0.00 (0.00, 0.00),0.00 (0.00, 0.00), respectively;Z=1.16, P>0.05 and Z=1.10, P>0.05).The FC analysis showed alterations from the right SN to bilateral cerebellum respectively among the three groups (Fright cerebellum=12.975, Fleft cerebellum=6.144;P<0.05);furthermore, there were significant increases in the RBD group compared with the PD group (t=-4.602,-5.080, P<0.005).The FC analysis showed reduced correlation from the right SN to the left prefrontal cortex in the RBD and the PD groups compared with the control group (t=-4.899,-3.500, P<0.005), but there was no statistically significant difference between the RBD and the PD groups (t=2.035, P>0.05).Conclusions There was abnormal FC from the SN to motor areas in RBD patients, and partial alterations were similar as PD patients.rfMRI provided an evidence that RBD might be presymptom of PD.

Objective To observe the performance of oral feeding in premature and to analyze its related factors so as to provide a basis for scientific management transforming from tube feeding to oral feeding.Methods This study designed the oral feeding observation table for premature by ourselves based on literature at home and abroad and revised by experts. Prospective observation and record was used to the rate and effects of feeding at the beginning of oral feeding and when the oral feeding was complete in 109 premature of neonatal intensive care unit at a class Ⅲ grade A hospital in Wenzhou from July 2015 to January 2016. The data were analyzed by the SPSS 19.0.Results There were statistically significant differences at the rate and effects of feeding in premature among different gestational ages, birth weight and Cornell medical indexes (P<0.05). When oral feeding was complete, there was a statistically significant difference at the rate of feeding in premature among different birth weight (P<0.05).Conclusions The feeding performance of premature is influenced by the gestational ages, birth weight and Cornell medical indexes at the beginning of oral feeding. With the growing experience in feeding, premature have good feeding performance when oral feeding was complete. Health care providers should select feeding patterns rationally according to the condition of premature and so on and promote the acquisition of independently oral feeding.
