Objective: There were associations between emotional abuse and neglect (EAN) and depression, but few studies had tested potential mechanisms underlying these relationships. We aimed to provide insights on how (the mediation role of neuroticism), and under what conditions (the moderator role of psychological resilience), led to a higher level of depression. Methods: This study was a cross-sectional study that used a random cluster sampling method. We randomly selected 3,993 participants from four junior middle schools in northern city of China. Participants were asked to complete four self-reported questionnaires, including the Childhood Trauma Questionnaire, Children Depression Inventory-Short Form, Chinese Big Five Personality Inventory Brief Version, and Chinese Resilience Scale. Results: The results showed that neuroticism mediated the associations between EAN and depression. In addition, the mediating effect of neuroticism was moderated by psychological resilience (p<0.05). Conclusion EAN and neuroticism could have an adverse impact on depression, and psychological resilience could alleviate these negative effects as a moderator. Our model suggested psychological resilience could be a particularly effective intervention point for victims of EAN.

Refractory angina is characterized by recurrent and persistent angina with a duration of not less than three months， which is related to reversible ischemia and hypoxia caused by coronary stenosis and obstruction. It mainly involves obstructive coronary artery disease and non-obstructive coronary artery disease with coronary artery spasm and coronary microvascular dysfunction. “Stasis and toxin” play an important role in the pathogenesis of cardiovascular diseases. The pathogenesis of stasis and toxin is stubborn filthy turbidity featured by slow accumulation and sudden onset，and rapid changes，which coincides with the characteristics of refractory angina which is complex and changeable，prolonged and difficult to cure. The pathogenesis of refractory angina involves a combination of underlying deficiency and excessive manifestation， with "stasis and toxin" playing a crucial role as an important pathological factor in the whole process of refractory angina. Traditional Chinese medicine （TCM） employs a holistic approach known as "activating blood circulation and removing toxins"， which is supplemented by various methods to tonify Qi and warm Yang， nourish the kidneys and invigorate the spleen， clear heat and transform phlegm. This approach applies anti-inflammatory measures， regulates lipid metabolism， inhibits oxidative stress and thrombus formation， protects endothelial function in blood vessels， as well as establishes collateral circulation for the prevention and treatment of refractory angina. Therefore，based on the theory of "stasis and toxin"，combined with TCM theory and modern medical research，this paper discusses the pathogenesis of refractory angina and the prevention and treatment strategy of TCM，and elucidates the reasons for the difficulty in curing refractory angina and the relationship between refractory angina and common angina pectoris，coronary microvascular dysfunction，coronary artery spasm and obstructive coronary artery disease，hoping to provide certain theoretical basis and clinical ideas for the prevention and treatment of refractory angina with TCM.

ObjectiveTo evaluate the clinical effectiveness and safety of Bairui Granules （百蕊颗粒） in the treatment of acute pharyngitis with wind-heat syndrome. MethodsA multicenter， double-blind， double-simulation， randomised controlled trial was conducted， in which 162 patients with acute pharyngitis and wind-heat syndrome from 7 centers were recruited， and each center was divided into trial group and control group on the ratio of 2∶1. In the trial group， 108 cases were orally administered with Bairui Granules plus Reyanning Granules （热炎宁颗粒） simulant， and in the control group， 54 cases were orally administered with Reyanning Granules plus Bairui Granules simulant for 5 days， with a follow-up visit on the 6th day. Full analysis set （FAS） analysis and per protocol set （PPS） were used for analysis， respectively. The primary efficacy index was the disappearance rate of sore throat after 5-day treatment； the secondary efficacy indexes were the disappearance rate of sore throat after 3-day treatment， as well as the visual analogue score （VAS） of sore throat before treatment， every day during the treatment， and follow-up on day 6， and the traditional Chinese medicine （TCM） syndrome score was performed before treatment and at the follow-up on day 6. The effectiveness on TCM syndrome was evaluated at the follow-up on day 6， and the changes of vital signs， blood routine， urine routine， liver functions， kidney function， the adverse events before and after the treatment were recorded， and safety analysis set （SS） was analysed. Results162 patients entered the FAS and SS analyses， and 158 cases （105 cases in the trial group and 53 cases in the control group） entered the PPS analysis. FAS analysis showed that the disappearance rate of sore throat after 5-day treatment was 80.56% （87/108） in the trial group and 64.81% （35/54） in the control group， and the difference between groups was statistically significant （χ² = 5.10， P = 0.0239）. PPS analysis showed that the disappearance rate of sore throat after 5-day treatment was 80.00% （84/105） in the trial group and 64.15% （34/53） in the control group， and the difference between groups was statistically significant （χ² =4.85， P = 0.0277）. FAS and SS analyses both showed that the difference in disappearance rate of sore throat between groups on 3-day treatment was not statistically significant （P＞0.05）. Compared with those before treatment， the VAS scores of sore throat were lower in both groups during treatment on day 2， 3， 4， 5， and follow-up on day 6 （P＜0.01）， but the difference between groups at each time point was not statistically significant （P＞0.05）. TCM syndrome scores of both groups at the follow-up were lower than that before treatment， and those of the trial group were lower than those of the control group （P＜0.01）. The cure rate and effective rate of TCM syndrome of the trial group were significantly higher than those of the control group （P＜0.01）. There was no significant difference in blood routine， urine routine， liver function， kidney function between groups before and after treatment （P＞0.05）， and no serious adverse events occured in both groups. ConclusionBairui Granules showed clinical effectiveness in the treatment of acute pharyngitis of wind-heat syndrome， and it could significantly improve the clinical symptoms， accelerate the disappearance time of sore throat with good safety.

Bone is a dynamic tissue undergoing continuous regeneration and reconstruction， and its metabolic activities are mainly regulated by bone formation mediated by osteoblasts and bone resorption mediated by osteoclasts. In addition， a variety of cells such as adipocytes， inflammatory cells， endothelial cells， and nerve cells can affect bone metabolism by changing the bone marrow microenvironment. The incidence of bone metabolic diseases caused by bone metabolism disorders is increasing with aging of the population. At present， the clinical treatment of bone metabolic diseases has the disadvantages of long cycle， high cost and many side effects. Therefore， there is an urgent need for safe and effective prevention and treatment drugs. Corylin is an isoflavonoid extracted from Psoraleae Fructus， which has a variety of pharmacological effects such as anti-inflammatory， anti-oxidation， anti-tumor， anti-atherosclerosis， attenuating obesity and improving insulin resistance. Studies have shown that corylin not only exerts osteoprotective effects by promoting osteoblast differentiation and inhibiting osteoclast differentiation， but also plays a positive role in bone metabolism by regulating lipid metabolism， inflammatory response， angiogenesis and anti-aging. The current review overviews the effects and mechanisms of corylin on regulating bone metabolism directly or indirectly， hoping to open up a new perspective for the prevention and treatment of osteoporosis， fracture， osteoarthritis and other related diseases.

ObjectiveTo carry out an epidemiological analysis on an outbreak of Mycoplasma pneumoniae infection at a welfare institution to provide a theoretical basis for the corresponding prevention and control measures. MethodsUsing the method of field epidemiological investigation， special field treatment was carried out in September 2022. Serum samples from cases and close contacts in the same ward area were collected for detection of nine respiratory tract infection pathogens （Mycoplasma pneumoniae， chlamydia， influenza， human metapneumosis， respiratory syncytial， human boca， parainfluenza type 1‒4 virus， and Middle East respiratory syndrome， severe acute respiratory syndrome coronavirus） by immunofluorescence immunoglobulin M （IgM） antibody test. ResultsA total of 14 Mycoplasma pneumoniae cases were identified， all of whom were residents of the welfare institution. The first case occurred on September 4， while the last case was reported on September 13. The incidence rate of the fifth ward area where the first case reported was 12.82% （10/78）， and it was 3.57% （3/84） in the third ward area and 1.20% （1/83） in the first ward area. There was a significant difference in incidence rates between ward areas （χ²=8.90， P<0.05）， but no significant difference was observed in age distribution and length of hospitalization. Thirty-three samples were collected for detection of nine kinds of IgM antibodies against respiratory pathogens. The results showed that the Mycoplasma pneumoniae IgM antibody was weakly positive in the 14 cases. ConclusionBased on the epidemiological history， clinical symptoms and laboratory tests， it was concluded that it was an outbreak of Mycoplasma pneumoniae infection within the welfare institution. Welfare institutions should continue to control the occurrence and outbreak of infection through effective routine hygiene， ventilation， and disinfection so as to ensure the health and safety of their clients.

BACKGROUND:Tissue engineering has brought new hope to the clinical challenge of liver failure,and the preparation of plant-derived decellularized fiber scaffolds holds significant importance in liver tissue engineering. OBJECTIVE:To prepare apple tissue decellularized scaffold material by using fresh apple slices and a solution of sodium dodecyl sulfate,and assess its biocompatibility. METHODS:Fresh apples were subjected to decellularization using phosphate buffer saline and sodium dodecyl sulfate solution,separately.Afterwards,the decellularized apple tissues and apple decellularized scaffold materials were decontaminated with phosphate buffer saline.Subsequently,scanning electron microscopy was used to assess the effectiveness of decellularization of the apple materials.Adipose-derived mesenchymal stem cells were extracted from the inguinal fat BALB/C of mice,and their expression of stem cell-related markers(CD45,CD34,CD73,CD90,and CD105)was identified through flow cytometry.The cells were then divided into a scaffold-free control group and a scaffold group.Equal amounts of adipose-derived mesenchymal stem cells were seeded onto both groups.The biocompatibility of the decellularized scaffold with adipose-derived mesenchymal stem cells was evaluated using CCK-8 assay,hematoxylin-eosin staining,and phalloidine staining.Cell adhesion and growth on the scaffold were observed under light microscopy and scanning electron microscopy.Furthermore,the scaffold was subdivided into the non-induced group and the hepatogenic-induced group.Adipose-derived mesenchymal stem cells were cultured on the decellularized apple scaffold,and they were cultured for 14 days in regular culture medium or hepatogenic induction medium for comparison.Immunofluorescent staining using liver cell markers,including albumin,cytokeratin 18,and CYP1A1,was performed.Enzyme-linked immunosorbent assay was used to detect the secretion of alpha fetoprotein and albumin.Additionally,scanning electron microscopy was employed to observe the morphology of the induced cells on the scaffold,verifying the expression of liver cell-related genes on the decellularized scaffold material.Finally,the cobalt-60 irradiated and sterilized decellularized apple scaffolds were transplanted onto the surface of mouse liver and the degradation of the scaffold was observed by gross observation and hematoxylin-eosin staining after 28 days. RESULTS AND CONCLUSION:(1)The scanning electron microscopy results revealed that the decellularized apple scaffold material retained a porous structure of approximately 100 μm in size,with no residual cells observed.(2)Through flow cytometry analysis,the cultured cells were identified as adipose-derived mesenchymal stem cells.(3)CCK-8 assay results demonstrated that the prepared decellularized apple tissue scaffold material exhibited no cytotoxicity.Hematoxylin-eosin staining and phalloidine staining showed that adipose-derived mesenchymal stem cells were capable of adhering and proliferating on the decellularized apple tissue scaffold.(4)The results obtained from immunofluorescence staining and enzyme-linked immunosorbent assay revealed that adipose-derived mesenchymal stem cells cultured on the decellularized apple scaffolds exhibited elevated expression of liver-specific proteins,including albumin,alpha-fetoprotein,cytokeratin 18,and CYP1A1.These results suggested that they were induced differentiation into hepatocyte-like cells possessing functional characteristics of liver cells.(5)The decellularized apple scaffold implanted at 7 days has integrated with the liver,with partial degradation of the scaffold observed.By 28 days,the decellularized apple scaffold has completely degraded and has been replaced by newly-formed tissue.(6)The results indicate that the decellularized scaffold material derived from apple tissue demonstrates favorable biocompatibility,promoting the proliferation,adhesion,and hepatic differentiation of adipose-derived mesenchymal stem cells.
