Objective To detect the expression change of ETFβin diabetic nephropathy rats and study the role of ETFβin fatty acid-induced apoptosis in renal tubules.Methods Diabetic nephropathy model was established by intraperitoneal injection of streptozotocin and unilateral nephrectomy.In vivo ETFβexpression was detected in renal cortex, as well as tubular injury evaluated.In vitro fatty acid-induced apoptosis in renal tubular cells NRK 52E model was established and ETFβrecombinant plasmid was constructed to be transfected into NRK 52E cells and furtherly to observe the effect of ETFβover-expression on the fatty acid-induced apoptosis.Results In the rats model of diabetic nephropathy induced by streptozotocin injection and unilateral nephrectomy, ETFβmRNA and protein expression were decreased as obvious tubular damage occurred.Fatty acids could induce apoptosis in NRK 52E, and ETFβover-expression reduced the apoptosis.Conclusion The expression of ETFβis decreased in diabetic nephropathy model , and ETFβover-expression can reduce apoptosis induced by fatty acid in renal tubular cells.

Objective: To explore associated factors of mobile phone dependence and its relation with psychological resilience among college students. Methods: College students from 5 universities in Hefei were randomly selected through multi-stage sampling (stratified clustering) and investigated with questionnaires. A total of 2 502 college students were included in the analysis. Results: Mobile phone dependence among college students differed by gender (χ2=18.25, P<0.01), residence (χ2=17.71, P<0.01), whether in a relationship(χ2=8.09, P<0.01), grade(χ2=19.58, P<0.01), only child(χ2=7.48, P<0.01), family economic status (χ2=17.43, P<0.01) and time spent in mobile phone (χ2=73.46，P<0.01) while no similar differences were found by family structure and length of mobile phone ownership. Spearman correlation showed negative correlation (P<0.01) between mobile phone dependence and psychological resilience. Logistic regression model results showed that female, not in a relationship, lower grade, less time spent in mobile phone and high psychological resilience were negatively correlated with mobile phone dependence. Compared with students from rural areas, urban area was positively associated with mobile phone dependence. Emotional control, family support, and interpersonal assistance associated with lower risk for mobile phone dependence. Conclusion Mobile phone dependence is affected by gender, relationship status, grade, usage duration, and residence. High psychological resilience associated negatively with risk for mobile phone dependence.

Objective:To establish a prediction model of risk factors for early Q-T interval prolongation after acute myocardial infarction (AMI), which helps prevent and reduce the occurrence of acute malignant events.Methods:This is a case-control study. A total of 100 patients with Q-T interval prolongation after AMI who received treatment at Heilongjiang Provincial Hospital from January 2018 to December 2022 were included in this study. An additional 100 patients without Q-T interval prolongation after AMI who concurrently received treatment in the same hospital were also included in this study. Two model groups, including model group 1 (with Q-T interval prolongation, n = 50) and model group 2 (without Q-T interval prolongation, n = 50), and two test groups, including test group 1 (with Q-T interval prolongation, n = 50) and test group 2 (without Q-T interval prolongation, n = 50), were designated. Logistic regression analysis was performed to construct a prediction model of risk factors for Q-T interval prolongation. The area under the receiver operating characteristic curve was determined to evaluate the prediction model. The value of the prediction model was validated in the test groups. Results:Multivariate logistic regression showed that female gender ( OR = 2.307, 95% CI: 0.09-0.91, P = 0.041) and heart failure ( OR = 3.087, 95% CI: 1.15-8.27, P = 0.025) were independent risk factors for early Q-T interval prolongation after AMI. The area under the receiver operating characteristic curve of the prediction model was 0.770, with a sensitivity of 84.0%, a specificity of 66.0%, the Jordan index of 0.44, and the corresponding optimal critical value of 0.43. This indicates good fit of the model. Conclusion:Female gender and heart failure are independent risk factors for early Q-T interval prolongation after AMI. The model constructed based on the above-mentioned risk factors fits well and has a high predictive value, which helps reduce the occurrence of early Q-T interval prolongation after AMI.

OBJECTIVE: To assess the value of copy number variation sequencing (CNV-seq) for the diagnosis of children with intellectual disability (ID), developmental delay (DD), and autistic spectrum disorder (ASD). METHODS: Forty patients with ID/DD/ASD referred to Nanshan Maternity and Child Health Care Hospital from September 2018 to January 2022 were enrolled. G-banded karyotyping analysis was carried out for the patients. Genomic DNA was extracted from peripheral blood samples and subjected to CNV-Seq analysis to detect chromosome copy number variations (CNVs) in such patients. ClinVar, DECIPHER, OMIM and other database were searched for data annotation. RESULTS: Among the 40 patients (including 30 males and 10 females), 16, 15 and 6 were diagnosed with ID, DD and ASD, respectively. One patient had combined symptoms of ID and DD, whilst the remaining two had combined ID and ASD. Four patients were found with abnormal karyotypes, including 47,XY,+mar, 46,XY,inv(8)(p11.2q21.2), 46,XX,del(5)(p14) and 46,XX[76]/46,X,dup(X)(p21.1q12). Chromosome polymorphism was also found in two other patients. CNV-seq analysis has detected 32 CNVs in 20 patients (50.0%, 20/40). Pathogenic CNVs were found in 10 patients (25.0%), 15 CNVs of uncertain clinical significance were found in 12 patients (30.0%), and 7 likely benign CNVs were found in 4 patients (10.0%). CONCLUSION Chromosome CNVs play an important role in the pathogenesis of ID/DD/ASD. CNV-seq can detect chromosomal abnormalities including microdeletions and microduplications, which could provide a powerful tool for revealing the genetic etiology of ID/DD/ASD patients.

Dissipative structure refers to a self-organized and orderly structure that exists far from equilibrium.The human body,considered a classical example,generates negative entropy through the exchange of matter,energy,and information with the environment to counteract the increase in entropy.In this paper,we organized theories and related research on dissipative structure and entropy,discussing their significance in regulating various aspects such as the human body,cancer,aging,and more.By selecting the special population of pregnant women,focusing on the information dimension,developing the corresponding information exchange scale(Cronbach's α>0.9),and proposing the information exchange index,we preliminarily explored the influence of the dissipative structure's information dimension on pregnancy health.The results showed a negative correlation between the information exchange index and anxiety scores during pregnancy(r =-0.35,P<0.001),with an OR value of 0.26(95%CI:0.08～0.80),preliminarily confirming the feasibility of conducting empirical research based on dissipative structure theory.If further relevant empirical studies are conducted,it is expected that new disease prevention strategies will be developed and new theories and methods will be provided for the field of public health.

AIM: To explore the possible mechanism of Radix Tetrastigma (RT) on anti-rheumatoid arthritis (RA). METHODS: The rat model of RA was established by intradermal injection of complete Freund]s adjuvant into the right hind foot of SD rats. RT Extract with different dosage was continuous intragastric administration for 3 weeks, then, the degree of foot swelling, arthritis index score, joint heat and grip of each rat was measured respectively. ELISA was used to detect the expression levels of Interleukin (IL) 6, IL-17, IL-10, tumor necrosis factor-α, and rheumatoid factor. Fully automatic hemorheometer was applied to measure hemorheology indexes. The number of CD4

Sclerostin, a protein secreted from osteocytes, negatively regulates the WNT signaling pathway by binding to the LRP5/6 co-receptors and further inhibits bone formation and promotes bone resorption. Sclerostin contributes to musculoskeletal system-related diseases, making it a promising therapeutic target for the treatment of WNT-related bone diseases. Additionally, emerging evidence indicates that sclerostin contributes to the development of cancers, obesity, and diabetes, suggesting that it may be a promising therapeutic target for these diseases. Notably, cardiovascular diseases are related to the protective role of sclerostin. In this review, we summarize three distinct types of inhibitors targeting sclerostin, monoclonal antibodies, aptamers, and small-molecule inhibitors, from which monoclonal antibodies have been developed. As the first-in-class sclerostin inhibitor approved by the U.S. FDA, the monoclonal antibody romosozumab has demonstrated excellent effectiveness in the treatment of postmenopausal osteoporosis; however, it conferred high cardiovascular risk in clinical trials. Furthermore, romosozumab could only be administered by injection, which may cause compliance issues for patients who prefer oral therapy. Considering these above safety and compliance concerns, we therefore present relevant discussion and offer perspectives on the development of next-generation sclerostin inhibitors by following several ways, such as concomitant medication, artificial intelligence-based strategy, druggable modification, and bispecific inhibitors strategy.
