Objective: To investigate the current status of benefit finding among young and middle-aged patients with type 2 diabetes mellitus (T2DM) and analyze its influencing factors, so as to provide a reference for improving the level of benefit finding in this population. Methods: From November 2022 to May 2023, young and middle-aged patients with T2DM aged 18-59 years hospitalized in the endocrinology departments of 2 tertiary hospitals in Hengyang City, Hunan Province were selected as survey subjects by a convenience sampling method. Basic demographic information was collected using a general questionnaire survey. Benefit finding, resourcefulness, and stigma were evaluated using the Benefit Finding Scale, the Chinese Version of the Resourcefulness Scale, and the Type 2 Diabetes Stigma Assessment Scale, respectively. A multiple linear regression model was used to analyze the influencing factors of benefit finding among young and middle-aged patients with T2DM. Results: A total of 305 young and middle-aged patients with T2DM were investigated, including 222 males (72.79%) and 83 females (27.21%). There were 231 cases aged 45-59 years, accounting for 75.74%. The scores for benefit finding, resourcefulness, and stigma were (42.86±6.06), (75.12±11.30), and (41.20±10.10), respectively. Multiple linear regression analysis showed that young and middle-aged patients with T2DM who were male (β′=0.088), aged 18-<45 years (β′=0.083), absence of diabetes complications (β′=0.124), and had higher resourcefulness scores (β′=0.679) had higher levels of benefit finding, while patients with higher stigma scores (β′=-0.097) had lower levels of benefit finding. Conclusion The level of benefit finding among young and middle-aged patients with T2DM was moderate, and was related to gender, age, diabetes complications, resourcefulness, and stigma.

This paper summarizes Professor LI Diangui's experience in treating vitiligo from the perspective of turbid toxins latent in the collaterals. Based on the theory of turbid-toxin， professor LI proposes that turbid toxins latent in the collaterals and qi-blood disharmony constitute the core pathogenesis of the onset and progression of the disease， and that resolving turbidity and removing toxins while harmonizing qi and blood should serve as the fundamental therapeutic principles. In clinical practice， treatment is tailored according to the evolution of the pathogenesis and syndrome differentiation. When stagnation of qi movement leads to the endogenous accumulation of turbid pathogens， treatment focuses on relieving constraint， dispersing turbidity， soothing the liver， and regulating qi， with a modified self-formulated Kaiyu Sanzhuo Decoction （开郁散浊汤）. When turbid pathogens overflow to the superficial tissues and obstruct the cutaneous collaterals， treatment aims to resolve blood stasis， disperse turbidity， regulate qi， and unblock the collaterals， using a modified self-formulated Tongluo Huazhuo Decoction （通络化浊汤）. When deficiency of healthy qi allows toxins to remain latent and the disease becomes prolonged， treatment emphasizes reinforcing healthy qi， eliminating turbidity， tonifying qi， and nourishing blood， with a modified self-formulated Fuzheng Quzhuo Decoction （扶正祛浊汤）.

Alopecia areata （AA） is a common hair loss disorder， and the core pathogenesis is the internal gene-ration of turbid toxin caused by qi movement disorder in the liver， spleen， and kidney. Turbid toxin serves as both a pivotal etiological trigger and a pathological driver of disease exacerbation. Clinically， AA can be classified into four principal patterns， including liver constraint with spleen deficiency， internal accumulation of damp-heat， liver-kidney depletion， and qi-blood depletion. Therapeutic strategies prioritize clearing and resolving turbid toxin while regulating the qi movement of the liver， spleen， and kidney. Accordingly， different formulas were applied. Self-formulated Shugan Jianpi Huazhuo Formula （疏肝健脾化浊方） is suggested to drain dampness， resolve turbidity， and unblock qi movement. Self-formulated Sanjiao Fenxiao Jiedu Formula （三焦分消解毒方） can be used to clear heat， drain dampness and resolve toxin. Self-formulated Zishen Yanggan Toudu Decoction （滋肾养肝透毒汤） can clear and vent latent toxins， while Self-formulated Guiqi Shengfa Didu Formula （归芪生发涤毒方） is employed to tonify qi and blood， purge toxins， and regenerate vitality. By differentiating and treating AA based on the functional patterns of the liver， spleen， and kidney， this approach expands the application scope of the turbid toxin theory and provides valuable insights for treatment of AA.

Corticotomy is a clinical procedure to accelerate orthodontic tooth movement characterized by the regional acceleratory phenomenon (RAP). Despite its therapeutic effects, the surgical risk and unclear mechanism hamper the clinical application. Numerous evidences support macrophages as the key immune cells during bone remodeling. Our study discovered that the monocyte-derived macrophages primarily exhibited a pro-inflammatory phenotype that dominated bone remodeling in corticotomy by CX3CR1^CreERT2; R26^GFP lineage tracing system. Fluorescence staining, flow cytometry analysis, and western blot determined the significantly enhanced expression of binding immunoglobulin protein (BiP) and emphasized the activation of sensor activating transcription factor 6 (ATF6) in macrophages. Then, we verified that macrophage specific ATF6 deletion (ATF6^f/f; CX3CR1^CreERT2 mice) decreased the proportion of pro-inflammatory macrophages and therefore blocked the acceleration effect of corticotomy. In contrast, macrophage ATF6 overexpression exaggerated the acceleration of orthodontic tooth movement. In vitro experiments also proved that higher proportion of pro-inflammatory macrophages was positively correlated with higher expression of ATF6. At the mechanism level, RNA-seq and CUT&Tag analysis demonstrated that ATF6 modulated the macrophage-orchestrated inflammation through interacting with Tnfα promotor and augmenting its transcription. Additionally, molecular docking simulation and dual-luciferase reporter system indicated the possible binding sites outside of the traditional endoplasmic reticulum-stress response element (ERSE). Taken together, ATF6 may aggravate orthodontic bone remodeling by promoting Tnfα transcription in macrophages, suggesting that ATF6 may represent a promising therapeutic target for non-invasive accelerated orthodontics.

Objective:To investigate the efficacy of percutaneous vertebroplasty through unilateral transverse process-pedicular for postmenopausal lumbar osteoporotic fractures.Methods:Retrospective analysis included 102 patients with postmenopausal lumbar osteoporotic fracture admitted to Hangzhou Fuyang Hospital of Orthopedics of Traditional Chinese Medicine from Jan. 2023 to Jan. 2024, who were divided into unilateral transverse process-pedicular group (UTPP group, n=48) and unilateral transverse pedicular group (UTP group, n=54) by means of approach. The changes of surgery-related indexes, imaging indexes and postoperative lumbar function recovery of the two groups were observed, and the patients were followed up for 1 year to record the incidence of secondary fracture of injured vertebra, fracture of adjacent vertebra and diffusion of bone cement. Results:The bone cement leakage rate in UTPP group was lower than that in UTP group ( P < 0.05), and there was no statsistically significant difference in operation time, fluoroscopy times, intraoperative blood loss, bone cement injection amount and hospital stay between the two groups ( P > 0.05). Before surgery, 3 months and 6 months after surgery, vertebral anterior margin height, middle vertebral height and sagittal cobb Angle between the two groups showed no significant differences ( P > 0.05). Visual analogue score (VAS) and oswestry disability index (ODI) between the two groups before surgery and 3 months after surgery had no statistically significant differences ( P > 0.05) ; VAS and ODI scores in UTPP group were lower than those in UTP group 6 months after surgery ( P < 0.05). The incidence of secondary fracture in UTPP group was lower than that in UTP group, while the height diffusion rate of bone cement was higher (all P < 0.05). The incidence of adjacent vertebral fracture between the two groups showed no statistically significant difference ( P > 0.05) . Conclusions:In postmenopausal patients with lumbar osteoporotic fractures, percutaneous vertebroplasty through unilateral transverse process-pedicular can effectively reduce the rate of intraoperative bone cement leakage, and has certain advantages in improving postoperative pain, promoting the recovery of postoperative lumbar function and reducing the risk of secondary fractures.

Interferon regulatory factor 1(IRF-1)is a member of the IRF family.It is the first transcription factor to be identified that could bind to the interferon-stimulated response element(ISRE)on the target gene and displays crucial roles in the interferon-induced signals and pathways.IRF-1,as an important medium,has all of the advantages of full cell cycle regulation,cell death signaling transduction,and reinforcing immune surveillance,which are well documented.Current studies indicate that IRF-1 is of vital importance to the occurrence and evolution of multifarious liver diseases,including but not limited to inhibiting the replication of the hepatitis virus(A/B/C/E),alleviating the progression of liver fibrosis,and aggravating hepatic ischemia-reperfusion injury(HIRI).The tumor suppression of IRF-1 is related to the clinical characteristics of liver cancer patients,which makes it a potential indicator for predicting the prognosis and recurrence of liver cancer;additionally,the latest studies have revealed other effects of IRF-1 such as protection against alcoholic/non-alcoholic fatty liver disease(AFLD/NAFLD),cholangiocarcinoma suppression,and uncommon traits in other liver diseases that had previously received little attention.Intriguingly,several compounds and drugs have featured a protective function in specific liver disease models in which there is significant involvement of the IRF-1 signal.In this paper,we hope to propose a prospective research basis upon which to help decipher translational medicine applications of IRF-1 in liver disease treatment.

Autophagy is mediated by multiple molecules and pathways. In cardiovascular diseases， autophagy can play a role through key signaling pathways such as phosphoinositide 3-kinase （PI3K）/protein kinase B （Akt）/mammalian target of rapamycin （mTOR）， adenosine monophosphate-activated protein kinase （AMPK）/mTOR， mitogen-activated protein kinases （MAPK）， p53， Wnt/β-catenin， etc. Traditional Chinese medicine （TCM） monomers for promoting blood circulation and removing blood stasis such as hydroxysafflor yellow A， ginsenoside Rb1， salidroside， ligustrin， curcumin， etc.， and TCM prescription and preparations such as Huangqi baoxin decoction， Taohong siwu decoction， Tongxinluo capsule， Shuangshen ningxin capsule， Suxiao jiuxin pills， etc. can regulate autophagy through the above-mentioned key signaling pathways， thereby alleviating the progression of cardiovascular diseases.

Objective To investigate the influence of type 2 diabetes mellitus(T2DM)on cognitive function and the effective connectivity with in the default mode network(DMN)in the brain.Methods A total of 93 hospitalized patients diagnosed with T2DM were enrolled in this study as T2DM group from The First Affiliated Hospital of Guangzhou University of Chinese Medicine during September 2021 to December 2022.Simultaneously,108 healthy individuals were recruited from the community as normal control(NC)group.The cognitive functions were evaluated in the two groups.A random dynamic causal modeling approach was employed to analyze the effective connectivity within DMN in both groups.Additionally,Pearson correlation analysis was performed to examine the association between differential connectivity,clinical indicators,and cognitive scores in both groups.Results In comparison to the NC group,T2DM individuals exhibited statistically significant reductions in scores in the auditory verbal learning test(AVLT)for immediate recall and the digit symbol substitution test(DSST)(P＜0.05).Additionally,they displayed a notable decrease in effective connectivity from the left lateral parietal cortex(LLPC)to the posterior cingulate cortex(PCC),as well as from the LLPC to the right lateral parietal cortex(RLPC)within the DMN(P＜0.05).Pearson correlation analysis unveiled a negative association between HbA1c levels and the strength of effective connectivity from LLPC to PCC.Conversely,a positive correlation was observed between AVLT(immediate)scores and the strength of effective connectivity from LLPC to PCC and LLPC to RLPC.Additionally,DSST scores displayed a positive correlation with the strength of effective connectivity from LLPC to PCC(P＜0.05).Conclusion Patients with T2DM display compromised effective connectivity from LLPC to PCC and LLPC to RLPC within the DMN network,and this alteration may associated with cognitive impairment.

Microneedles can penetrate the skin barrier to deliver drugs without touching the nociceptive nerves， to effectively increase the efficiency of transdermal drug delivery and improve patient compliance. Exosomes have multiple physiological functions and good biocompatibility， and are natural nanoscale drug carriers. This paper reviews the pathways and advantages of exosomes combined with microneedles for the treatment of diseases， and describes the current research status of exosome microneedle drug delivery system in various diseases. Exosome microneedles can be divided into two categories： （1） exosomes as therapeutic agents， their unique physiological origin can effectively avoid the toxicity and immunogenicity of conventional drugs and other problems； combined with microneedles directly in the specific medication site can greatly improve the metabolic consumption of oral drug delivery and patient compliance of injection drug delivery. （2） Exosomes as drug carriers， their natural vesicle structure and endogenous characteristics can protect the metabolism of foreign drugs in the body and enhance the targeting； combined with microneedles can effectively solve the problem of transdermal delivery of drugs with high efficacy but poor stability. Exosome microneedle drug delivery system is still in the laboratory stage， but it has shown great development prospects in repairing spinal cord injury， promoting diabetic ulcer wound healing， germinating， intervening myocardial infraction， relieving chronic pain and other diseases.
