Objective To explore the effect and mechanism of Zuogui Jiangtang Jieyu Formula(ZGJTJYF)in treating diabetes-related depression by regulating glutamate receptor 2(GluR2).Methods The primary isolated and cultured hippocampal neurons of SD rats were used.The experiment consisted of normal,model,blank serum(10％blank serum),positive drug(10％[metformin+fluoxetine]drug-containing serum),20％ZGJTJYF group,10％ZGJTJYF group,10％ZGJTJYF+GluR2 knockdown group,and 10％ZGJTJYF+GluR2 overexpression group(with corresponding volume fractions of ZGJTJYF drug-containing serum added).The ZGJTJYF+GluR2 knockdown and overexpression groups,were transfected with lentivirus to obtain hippocampal neurons with either GluR2 overexpression or knockdown.The glucose(150 mmol/L)and corticosterone(200 μmol/L)were used for 18 h to establish an in vitro cell model of hippocampal neurons in diabetes-related depression.After 24 h of successful modeling,the corresponding serum was added to each group for intervention.After 24 h of intervention,the morphological structure of hippocampal neurons was observed using an optical microscope.Biochemical methods were used to determine the glucose and insulin content in cell supernatant.An enzyme-linked immunosorbent assay was used to detect 5-hydroxytryptamine(5-HT)and dopamine(DA)levels in the cell supernatant,and the microtubule-associated protein 1A/1B light chain 3 autophagy double-labeled adenovirus(mRFP-GFP-LC3)autophagy fluorescence double labeling method was used to detect the average fluorescence intensity of LC3 protein in hippocampal neurons.Nissl staining was used to observe synaptic damage in hippocampal neurons,and an immunofluorescence method was used to detect the protein expression of Parkin,phosphatase and tensin homolog-induced putative kinase 1(PINK1),regulating synaptic membrane exocytosis 3(RIMS3),synapsin 1(SYN1),postsynaptic density-95(PSD-95),synapse-associated protein 102(SAP 102),and GluR2 in hippocampal neurons.Realtime fluorescence PCR was used to detect GluR2 mRNA expression in hippocampal neurons,while Western blotting was employed to assess the expression of mitophagy proteins Parkin and PINK1 in these neurons.Results Compared to the normal group,the model group and blank serum group showed structural damage to hippocampal neurons,increased glucose content in cell supernatant,decreased insulin,5-HT,and DA content,increased average fluorescence intensity of LC3,Parkin,and PINK1,decreased average fluorescence intensity of RIMS3,SYN1,PSD-95,SAP 102,and GluR2,decreased GluR2 mRNA expression,increased protein expression of Parkin and PINK1(P＜0.05),and decreased Nissl bodies.Compared to the model group and blank serum group,the above indicators in each administration group were improved to varying degrees(P＜0.05).Compared to the positive drug group,the average fluorescence intensity of LC3,Parkin,and PINK1 decreased,Parkin and PINK1 protein expression decreased,and the average fluorescence intensity of GluR2,SYN1,and PSD-95 increased in 10％ZGJTJYF,20％ZGJTJYF group,and 10％ZGJTJYF+GluR2 overexpression group(P＜0.05).Compared to 10％and 20％ZGJTJYF groups,10％ZGJTJYF+GluR2 knockdown group showed a decrease in 5-HT content,an increase in average fluorescence intensity of LC3 and Parkin,a decrease in average fluorescence intensity of SYN1,PSD-95,and GluR2,a decreased in GluR2 mRNA expression,and an increase of Parkin and PINK1 protein expression(P＜0.05).In contrast,the above indicators were improved to varying degrees in 10％ZGJTJYF+GluR2 overexpression group(P＜0.05).Compared to 10％ZGJTJYF+GluR2 knockdown group,the above abnormal indicators in 10％ZGJTJYF+GluR2 overexpression group were reversed to varying degrees(P＜0.05).Conclusion ZGJTJYF has a protective effect on synaptic damage of hippocampal neurons in diabetes-related depression,and its mechanism may be related to the upregulation of GluR2 and the inhibition of mitophagy over activation.

This consensus was developed by the Orthodontic Society of the Chinese Stomatological Association to provide a systematic, scientific, and practical guideline for informed consent in orthodontic care. Orthodontic treatment is typically lengthy, highly individualized, and involves multiple factors such as growth and development, occlusal function, and facial esthetics. Rapid technological advances and diverse risk profiles make the traditional reliance on orthodontist experience or institutional templates insufficient to ensure patients′ full understanding and autonomous decision-making. To address this, the expert panel conducted extensive reviews of domestic and international guidelines, analyzed representative dispute cases, and performed multicenter patient-clinician surveys. Using a multi-round Delphi method, the group established a standardized informed consent framework covering the initial consultation, treatment, and retention phases. The consensus emphasizes that informed consent is not only a fundamental legal and ethical requirement but also a key step in building trust, improving patient compliance, and enhancing treatment satisfaction. Orthodontists should clearly and comprehensively explain treatment plans, potential risks, uncertainties, and associated costs, while respecting the autonomy of patients or guardians, and maintain continuous communication and dynamic evaluation throughout the treatment process. The release of this consensus provides unified and authoritative guidance for clinical orthodontics, helping to standardize informed consent, enhance its transparency, safeguard patient rights, reduce medical risks, and promote high-quality, sustainable development of orthodontic practice.

To analyze the relationship between serum non-HDL-C levels and cardiovascular disease (CVD) mortality in community populations. A retrospective cohort study was conducted using the Yuecheng District Health Information Platform in Shaoxing City, Zhejiang Province. The study cohort included individuals aged 40 years or older with no prior history of CVD who underwent physical examinations at Yuecheng District healthcare institutions between January and December 2019. A total of 39 038 participants were included, including 19 085 males (48.9%) and 19 953 females (51.1%), with a mean age of (73.64±9.10) years. The mean follow-up duration was 52.3 months. During follow-up, 1 227 CVD death events occurred. The results indicated a significant overall association between non-HDL-C levels and the risk of CVD mortality, including coronary heart disease (CHD) and stroke. Cox models indicated that, using the ideal level of non-HDL-C as the reference, the hazard ratios (HRs) for risk of CVD death in the suitable level, borderline elevated level and elevated level groups were 1.24 (95% CI: 1.08-1.42), 1.57 (95% CI: 1.34-1.85) and 2.31 (95% CI: 1.87-2.86), respectively. The corresponding HRs for CHD death were 1.39 (95% CI: 1.10-1.76), 1.69 (95% CI: 1.28-2.12) and 2.53 (95% CI: 1.76-3.64), respectively. Subgroup analysis revealed significant interaction effects between non-HDL-C and sex, smoking, alcohol consumption, and diabetes (all P interaction<0.05). Sensitivity analyses confirmed that results were consistent with the primary findings regarding the association between non-HDL-C and CVD mortality risk. In conclusion, increasing non-HDL-C levels are associated with higher risks of death from cardiovascular diseases, including stroke and CHD. The risk of CVD death associated with elevated non-HDL-C is greater among males, individuals with a history of diabetes, smokers or drinkers. In the future, attention should be paid to the monitoring of non-HDL-C in community health management, and the intensive and personalized management of blood lipids in high-risk population should be strengthened.

BACKGROUND:Growth factor is the key effect molecule that plays a role in platelet-rich plasma in clinical treatment.There are differences in the concentration of growth factor after different activators activate platelet-rich plasma,which is an important factor affecting clinical efficacy. OBJECTIVE:To analyze the influence of different activators on the mass concentration of growth factors in platelet-rich plasma. METHODS:Totally 12 healthy volunteers were recruited to collect EDTA-K2 anticoagulant venous blood.Secondary centrifugation was used to prepare platelet-rich plasma.The difference in mass concentrations of growth factors was compared between venous blood and platelet-rich plasma.The platelet-rich plasma was mixed with four activators(normal saline,thrombin,calcium gluconate,calcium gluconate+thrombin)according to the volume ratio of 10:1,and incubated in a constant temperature water bath at 37 °C for 30 minutes.After centrifugation,the supernatant was extracted and the mass concentration of growth factor was detected.The bacterial growth in supernatant was measured by blood agar plate.Pearson correlation was used to analyze the correlation between different activators and the mass concentration of growth factor in platelet-rich plasma,and the correlation between the value of thrombocytometer and the mass concentration of growth factors in platelet-rich plasma. RESULTS AND CONCLUSION:(1)The mass concentrations of platelet-derived growth factor-BB,platelet-derived growth factor-AB,vascular endothelial growth factor,and epidermal growth factor in platelet-rich plasma were 8.7,22.2,2.3,and 2.8 times of those in venous blood,respectively(P<0.05).(2)Compared with normal saline group,the mass concentrations of platelet-derived growth factor BB,platelet-derived growth factor AB,vascular endothelial growth factor,and epidermal growth factor were increased in the thrombin group,calcium gluconate group,and calcium gluconate+thrombin group(P<0.05).The mass concentration of platelet-derived growth factor BB in the thrombin group and calcium gluconate group was higher than that in the calcium gluconate+thrombin group(P<0.05),and the mass concentration of platelet-derived growth factor AB in the thrombin group was higher than that in the calcium gluconate group and calcium gluconate+thrombin group(P<0.05).Epidermal growth factor mass concentration in the thrombin group was lower than that in the calcium gluconate group and calcium gluconate+thrombin group(P<0.05).(3)The results of blood agar plate test showed no bacterial growth in the supernatant of the four groups.(4)Pearson correlation analysis showed that the mass concentration of platelet-derived growth factor BB in platelet-rich plasma was strongly positively correlated with thrombin(r=0.683,P<0.05),and the mass concentration of vascular endothelial growth factor was strongly positively correlated with thrombin,calcium gluconate,calcium gluconate+thrombin stimulant(r=0.730,0.789,0.686,P<0.05).There was no correlation between the value of thrombocytometer and the mass concentration of four kinds of growth factors(P>0.05).(5)The results suggest that different activators have an impact on the concentration of growth factors in platelet-rich plasma.It is suggested to choose different activators to improve clinical efficacy according to different growth factor mass concentrations and treatment needs.
