ObjectiveTo provide a reference for the establishment of an ideal corneal neovascularization (CNV) animal model by summarizing the modeling characteristics of CNV animal models. MethodWith "CVN" as the theme word, this paper searched the China National Knowledge Infrastructure (CNKI), Wanfang, Chinese medical journals full-text database, and PubMed database and screened out relevant literature on CNV animal experiments from 2013 to 2023. The database was established by Excel 2021, and the experimental animal strain, gender, modeling method, detection index, and application category were sorted out. The characteristics of the CNV animal model were analyzed. ResultAfter comparative analysis, it was found that the animal strains were Sprague-Dawley rats (87 times, 29.49%) and New Zealand white rabbits (52 times, 17.63%). Male animals were recommended. Most modeling methods for efficacy verification and mechanism studies were the alkali burn method. Index detection methods included apparent index observation, histopathological detection, immunohistochemistry (IHC), Western blot, and various polymerase chain reaction (PCR) tests. Detection indexes included apparent indication, corneal histopathology, CNV regulation, etc. ConclusionThe CNV model of SD rats induced by the alkali burn method is recommended for model replication, and the indexes are mainly selected from the growth of CNV, corneal histopathological test, and vascular endothelial growth factor (VEGF)-related test. In addition, according to the demand, the corneal apparent indication and the basic indexes related to the regulation of CNV, such as vascular endothelial growth factor receptor 2 (VEGFR2), basic fibroblast growth factor (bFGF), and secretogranin Ⅲ (Scg3) are also selected. Clinical treatment of CNV relies on anti-inflammatory drugs and anti-VEGF drugs, and there is a lack of application of traditional Chinese medicine (TCM), so the model needs to be improved by adding elements of TCM syndromes.

Objective:
To investigate the current status and relationship between loneliness and negative emotional symptoms among first generation college students in the family, so as to provide reference for improving mental health of this population.
Methods:
A convenience sampling method was used to select 3 017 college students from 10 colleges and universities in Guangdong Province and Yunnan Province, China, in May 2023. Questionnaires were administered to the students, and the Depression Anxiety Stress Scale (DASS-21) and the short form of the University of California at Los Angeles Loneliness Scale (ULS-6) were employed.
Results:
The total ULS-6 score of first generation college students in the family was (12.38±4.16), while the score of non first generation college students in the family was (11.89±4.38), with a statistically significant difference ( t=2.79, P <0.05). The total DASS-21 score of first generation college students in the family was (71.13±26.97), while the score of non first generation college students in the family was (70.20±26.66), with a statistically significant difference ( t=2.69, P <0.05). Among the first generation college students in the family, male students experienced more DASS-21 score (77.55±29.36) than female students (70.43±25.03)( t =5.79, P <0.05). Urban students (12.00±4.15, 70.34±25.68) reported lower levels of loneliness score and DASS- 21 score than rural students (12.62±4.15, 74.93±27.63), and the depression subscale scores showed statistically significant differences among students with different professional achievement rankings ( t/F =-3.42, -3.94, 4.25, P <0.05). There was a positive correlation between loneliness, depression, anxiety, pressure and DASS-21 scales of first generation college students in the family ( r=0.64, 0.62, 0.64, 0.66, P <0.01). The linear regression analysis results showed a positive correlation between loneliness and all dimensions and total scores of the DASS-21, explaining 44% of the variance in negative emotional symptoms.
Conclusions
A positive correlation is found between loneliness and negative emotional symptoms among first generation college students in the family. Improving the loneliness of the first generation college students in the family can reduce their negative emotional symptoms and improve their mental health level.

Objective To investigate the impact of anti-reflux modified duodenal exclusion surgery on glucose metabolism in rats with type 2 diabetes mellitus (T2DM), and to elucidate the role of the duodenum in maintaining glucose homeostasis. MethodsForty male Sprague-Dawley rats aged 5 weeks were fed a high-fat diet and induced with T2DM using low-dose streptozotocin. Thirty-six rats that met the T2DM model criteria were randomly divided into three groups: the simple duodenal exclusion surgery group (DE group), the anti-reflux modified duodenal exclusion group (MDE group), and the sham operation group (SO group), with 12 rats in each group. Gastroenterography was performed 4 weeks after surgery, and the body weight, fasting blood glucose levels, and serum glucagon-like peptide-1 (GLP-1) concentrations were measured before surgery and at 1, 2, 4, and 8 weeks post-surgery. Eight weeks post-surgery, the rats were euthanized, and a 1 cm segment of the biliopancreatic loop was collected from each group for pathological sectioning and HE staining to observe the intestinal mucosal villus length under an optical microscope. Results Gastroenterography showed that there was significant reflux of the contrast agent into the duodenal lumen in the DE group, while no reflux was observed in the MDE group. At one week post-surgery, the body weights of rats in all three groups significantly decreased compared to before surgery (P<0.05), and then the body weights of all groups increased over time, with no significant differences between the groups (P>0.05). Compared with the SO group, the fasting blood glucose levels in the MDE and DE groups significantly decreased at all time points post-surgery (P<0.05), while GLP-1 concentrations significantly increased (P<0.05). The fasting blood glucose levels in the MDE group were lower than those in the DE group at all time points post-surgery (P<0.05), but there were no significant differences in serum GLP-1 concentrations between the MDE and DE groups (P>0.05). Regarding intestinal mucosal morphology, the villus lengths of the biliopancreatic loops in the MDE group were significantly shorter than those in the DE and SO groups (P<0.05). Conclusion Anti-reflux modified duodenal exclusion surgery effectively improves glucose metabolism in T2DM rats by preventing the reflux of chyme into the diverted duodenum, thereby enhancing its hypoglycemic effect.

Canine cognitive dysfunction syndrome (CDS) is a neurodegenerative disease that causes cognitive and behavioral disorders and reduces the quality of life in dogs and their guardians. This study reviewed the complementary and alternative medicine (CAM) for CDS and compared the diagnosis and therapy of CAM between CDS in canines and dementia in humans. The evaluation tools for the diagnosis of CDS and dementia were similar in the neurological and neuropsychiatric examinations, daily life activity, cognitive tests, and neuroimaging, but the evaluation for dementia was further subdivided. In CAM, pattern identification is a diagnostic method for accurate, personalized treatment, such as herbal medicine. For herbal medicine treatment of cognitive impairment in canines and humans, a similar pattern identification classified as deficiency (Qi, blood, and Yin) and Excess (phlegm, Qi stagnation, and blood stasis) is being used. However, the veterinary clinical basis for verifying the efficacy and safety of CAM therapies for CDS is limited. Therefore, based on CAM evidence in dementia, it is necessary to establish CDS-targeted CAM diagnostic methods and therapeutic techniques considering the anatomical, physiological, and pathological characteristics of dogs.

Objective :
To explore whether miR⁃9 affects the proliferation of neural stem cells (NSCs) by regulating β ⁃tubulin Ⅲ and glial fibrillary acidic protein (GFAP) .
Methods :
NSCs cells were isolated and cultured on the purchased healthy pregnant mice and the isolated cells were divided into NO group ( non⁃transfected NSCs cell line) , NN group (NSCs transfected with miR⁃9 ⁃NC) , NM group (NSCs transfected) transfected with miR⁃9 mimics) , NI group ( transfected with miR⁃9 inhibitor) . Nestin was identified by immunofluorescence , the contents of Mir⁃9 , β ⁃tubulin Ⅲ and GFAP were measured by QRT⁃PCR , the proliferation of NSCs was measured by MTT method , the apoptosis of NSCs was measured by flow cytometry , and the protein expressions of Mir⁃9 , β ⁃tubulin Ⅲ and GFAP were detected by Western blot.
Results :
The detection index Nestin of NSCs for 24 h after cell passage was positive in 90% of the NSCs , and co⁃localized with the nucleus , indicating the successful isolation of NSCs. The expression of miR⁃9 mRNA in NSCs of the NM group was the highest among the four groups , indicating that the transfection was successful. Among the four groups , β ⁃tubulin Ⅲ mRNA and protein expression was the highest in the NM group , and the GFAP mRNA and protein expression was the lowest. The NI group was the opposite (P < 0. 05) . In the four groups after 24 h , the cell activity of NSCs in the NM group was the strongest and showed a trend of gradually increasing with time (P < 0. 05) . The cell activity of NI was significantly weaker than that of the other three groups (P < 0. 05) . Among the four groups , the apoptosis rate of the NM group was lower than that of the other three groups (P < 0. 05) , and the apoptosis rate of NI was higher than that of the other three groups (P < 0. 05) . The difference in the above indicators between the NO group and the NN group was smaller.
Conclusion
Overexpressed miR⁃9 promotes the proliferation of NSCs by promoting the expression of β ⁃tubulin Ⅲ and inhibiting the expression of GFAP.

Background:
The dietary agent sulforaphane (SFN) has been reported to reduce diabetes-induced renal fibrosis, as well as inhibit histone deacetylase (HDAC) activity. Bone morphologic protein 7 (BMP-7) has been shown to reduce renal fibrosis induced by transforming growth factor-beta1. The aim of this study was to investigate the epigenetic effect of SFN on BMP-7 expression in diabetes-induced renal fibrosis.
Methods:
Streptozotocin (STZ)-induced diabetic mice and age-matched controls were subcutaneously injected with SFN or vehicle for 4 months to measure the in vivo effects of SFN on the kidneys. The human renal proximal tubular (HK11) cell line was used to mimic diabetic conditions in vitro. HK11 cells were transfected to over-express HDAC2 and treated with high glucose/palmitate (HG/Pal) to explore the epigenetic modulation of BMP-7 in SFN-mediated protection against HG/Pal-induced renal fibrosis.
Results:
SFN significantly attenuated diabetes-induced renal fibrosis in vivo. Among all of the HDACs we detected, HDAC2 activity was markedly elevated in the STZ-induced diabetic kidneys and HG/Pal-treated HK11 cells. SFN inhibited the diabetes-induced increase in HDAC2 activity which was associated with histone acetylation and transcriptional activation of the BMP-7 promoter. HDAC2 over-expression reduced BMP-7 expression and abolished the SFN-mediated protection against HG/Pal-induced fibrosis in vitro.
Conclusion
Our study demonstrates that the HDAC inhibitor SFN protects against diabetes-induced renal fibrosis through epigenetic up-regulation of BMP-7.
