The aim of this study is to analyze the research hotspots and development trends in the field of pathogenesis of diabetic nephropathy in China from 2013 to 2022. Based on China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform, China Science and Technology Journal Database, China Biology Medicine disc, Web of Science core collection and PubMed database, the related literatures in the field of pathogenesis of diabetic nephropathy in China from 2013 to 2022, were retrieved to establish the database, and the VOSviewer software was used for bibliometric analysis. A total of 1 664 Chinese and 2 149 English literatures are included in this study. The scientific research results from 2013 to 2022 have shown an overall increasing trend. The research hotspots in the field of pathogenesis of diabetic nephropathy in China are mainly concentrated in Podocytes, Oxidative stress, Inflammation, Renal fibrosis, Urine protein, etc. The frontier hotspots in this field include Biomarkers, Nrf2, Gut microbiota, NLRP3 inflammasome, Apoptosis, MicroRNA, etc. Through visual analysis, the research hotspots and frontier trends of the pathogenesis of diabetic nephropathy in China can be visually presented, and then provide new ideas and directions for the further in-depth research on the pathogenesis of diabetic nephropathy.

Abstract
Obesity is characterized by the excessive accumulation of the white adipose tissue (WAT), but healthy expansion of WAT via adipocyte hyperplasia can offset the negative metabolic effects of obesity. Thus, identification of novel adipogenesis regulators that promote hyperplasia may lead to effective therapies for obesity-induced metabolic disorders. Using transcriptomic approaches, we identified transmembrane BAX inhibitor motif-containing 1 (TMBIM1) as an inhibitor of adipogenesis. Gain or loss of function of TMBIM1 in preadipocytes inhibited or promoted adipogenesis, respectively. In vivo, in response to caloric excess, adipocyte precursor (AP)-specific Tmbim1 knockout (KO) mice displayed WAT hyperplasia and improved systemic metabolic health, while overexpression of Tmbim1 in transgenic mice showed the opposite effects. Moreover, mature adipocyte-specific Tmbim1 KO did not affect WAT cellularity or nutrient homeostasis. Mechanistically, TMBIM1 binds to and promotes the autoubiquitination and degradation of NEDD4, which is an E3 ligase that stabilizes PPARγ. Our data show that TMBIM1 is a potent repressor of adipogenesis and a potential therapeutic target for obesity-related metabolic disease.

Abstract
Accurate segmentation of the jaw (i.e., mandible and maxilla) and the teeth in cone beam computed tomography (CBCT) scans is essential for orthodontic diagnosis and treatment planning. Although various (semi)automated methods have been proposed to segment the jaw or the teeth, there is still a lack of fully automated segmentation methods that can simultaneously segment both anatomic structures in CBCT scans (i.e., multiclass segmentation). In this study, we aimed to train and validate a mixed-scale dense (MS-D) convolutional neural network for multiclass segmentation of the jaw, the teeth, and the background in CBCT scans. Thirty CBCT scans were obtained from patients who had undergone orthodontic treatment. Gold standard segmentation labels were manually created by 4 dentists. As a benchmark, we also evaluated MS-D networks that segmented the jaw or the teeth (i.e., binary segmentation). All segmented CBCT scans were converted to virtual 3-dimensional (3D) models. The segmentation performance of all trained MS-D networks was assessed by the Dice similarity coefficient and surface deviation. The CBCT scans segmented by the MS-D network demonstrated a large overlap with the gold standard segmentations (Dice similarity coefficient: 0.934 ± 0.019, jaw; 0.945 ± 0.021, teeth). The MS-D network–based 3D models of the jaw and the teeth showed minor surface deviations when compared with the corresponding gold standard 3D models (0.390 ± 0.093 mm, jaw; 0.204 ± 0.061 mm, teeth). The MS-D network took approximately 25 s to segment 1 CBCT scan, whereas manual segmentation took about 5 h. This study showed that multiclass segmentation of jaw and teeth was accurate and its performance was comparable to binary segmentation. The MS-D network trained for multiclass segmentation would therefore make patient-specific orthodontic treatment more feasible by strongly reducing the time required to segment multiple anatomic structures in CBCT scans.

Abstract
OBJECTIVE To assess the prognosis of rare advanced.cervical carcinoma with post-radical-radiation surgery and to compare the clinic value between further surgery treatment group and non-surgery group after radical radiation therapy. MATERIALS AND METHODS From January 2002 to July 2010 there were 68 patients with advanced stage cervical carcinoma retrospectively analysed in Maternal and Child Health Hospital of Jiangxi Province. All patients were confirmed by histopathology before treatment, and clinical staging was based on updated 2009 FIGO staging. All patients were Stage Ib2 (local advanced) and more severe. There were 36 patients (29 adenocarcinoma (AC), six adenosquamous carcinoma (ASC), and one undifferentiated carcinoma) classified into observation group that was treated with radical radiation therapy + surgery (total hysterectomy + bilateral salpingo-oophorectomy); other 32 patients (26 AC, five ASC, and one undifferentiated carcinoma) classified into control group that was treated with radical radiation therapy with no further surgery. The radical radiation therapy included external-beam radiation and intracavitary therapy, standard point A dose added up to 85 Gy (these doses are recommended for most patients based on summation of conventional external-beam fractionation and low-dose rate 40-70 cGy/h brachytherapy equivalents), and 45-55 Gy was given to point B. All of the patients were followed up. The average follow-up time was 65.6 months and the survival rate between two groups were compared and analyzed whether there was residual lesion, metastasis, lymph vascular space invasion (LVSI) in the observation group. RESULTS In observation group there were 15 patients found positive. The positive rate was 41.7% (15/36), in which there nine cases with LVSI and residual foci, four cases with uterus invasion, and one case with only residual foci. Both of the two groups were followed up and the average follow-up time was 65.6 months (range 36-136). In observation group there were 25 cases that have survived until now and the average survival time was 66.6 months (range 36-136). Eleven patients died with an average survival time of 10.4 months (range 2-37). In control group there are 22 cases that survived until now (July 2013); the average survival time was 64.4 months (range 36-136). Ten patients died with an average survival time of 10.3 months (range 3-28). Three cases experienced serious complication in observation group and two cases in control group. There was no significant difference in survival time between the two groups. CONCLUSION Due to low efficacy results, post-radical-radiation surgery is not a feasible treatment regimen for rare advanced cervical carcinoma.
