From birth to adulthood, we often align our behaviors, attitudes, and opinions with a majority, a phenomenon known as social conformity. A seminal framework has proposed that conformity behaviors are mainly driven by three fundamental motives: a desire to gain more information to be accurate, to obtain social approval from others, and to maintain a favorable self-concept. Despite extensive interest in neuroimaging investigation of social conformity, the relationship between brain systems and these fundamental motivations has yet to be established. Here, we reviewed brain imaging findings of social conformity with a componential framework, aiming to reveal the neuropsychological substrates underlying different conformity motivations. First, information-seeking engages the evaluation of social information, information integration, and modification of task-related activity, corresponding to brain networks implicated in reward, cognitive control, and tasks at hand. Second, social acceptance involves the anticipation of social acceptance or rejection and mental state attribution, mediated by networks of reward, punishment, and mentalizing. Third, self-enhancement entails the excessive representation of positive self-related information and suppression of negative self-related information, ingroup favoritism and/or outgroup derogation, and elaborated mentalizing processes to the ingroup, supported by brain systems of reward, punishment, and mentalizing. Therefore, recent brain imaging studies have provided important insights into the fundamental motivations of social conformity in terms of component processes and brain mechanisms.

ObjectiveTo observe the effect of Sanhuang Tangshenkang on the Wnt/β-catenin signaling pathway in the bone tissue of diabetic rats. MethodA high-sugar and high-fat diet was administered for 4 weeks, along with intraperitoneal injection of freshly prepared 2% streptozotocin (pH 4.5) at 30 mg·kg-1 body weight to induce a diabetes model in rats. The rats with diabetes were randomly divided into model group, low- and high-dose Sanhuang Tangshenkang groups (12.8, 38.4 g·kg-1), and Gushukang group (1.8 g·kg-1) according to the blood glucose level. Rats of the same age were fed on a regular diet and assigned to the control group. After 12 weeks of respective treatments with drugs or physiological saline, the fasting blood glucose (FBG) levels of the rats were measured using an automated biochemical analyzer. Enzyme-linked immunosorbent assay (ELISA) was used to detect fasting serum insulin (FINS), bone-specific alkaline phosphatase (BALP), and tartrate-resistant acid phosphatase (TRAP) levels. Micro-computed tomography (Micro-CT) was used to scan the femurs of rats to observe bone tissue microstructure and measure bone mineral density (BMD). Hematoxylin-eosin (HE) staining and safranin O/fast green staining were performed to observe pathological changes in the femoral bone tissue. Immunohistochemistry (IHC) and Western blot were used to detect the expression of Wnt3a, low-density lipoprotein receptor-related protein 5 (LRP-5), and β-catenin proteins. ResultCompared with the control group, the model group showed a significant increase in FBG, FINS, and TRAP levels (P<0.01), a significant decrease in BALP level (P<0.01), a significant decrease in BMD (P<0.01), and disorganized, elongated, and sparse bone trabecular structures with fractures and increased lipid droplets. Additionally, the expression of Wnt3a, LRP-5, and β-catenin proteins decreased (P<0.05, P<0.01). Compared with the model group, the low- and high-dose Sanhuang Tangshenkang groups showed a reduction in FBG and an increase in BALP (P<0.05). The low-dose Sanhuang Tangshenkang group also exhibited a decrease in FINS (P<0.05). All treatment groups showed a significant decrease in TRAP (P<0.01), varying degrees of improvement in BMD (P<0.05, P<0.01)), increased and denser bone trabeculae with more regular arrangements and reduced lipid droplets, and improved bone microstructure morphology. The average optical density values of Wnt3a, LRP-5, and β-catenin proteins were significantly increased in all drug-treated groups (P<0.05, P<0.01), and the expression of Wnt3a, LRP-5, and β-catenin proteins was elevated (P<0.05, P<0.01). ConclusionSanhuang Tangshenkang may regulate the imbalance of the Wnt/β-catenin signaling pathway by increasing the expression of Wnt3a, LRP-5, and β-catenin proteins in bone tissue, which may promote bone formation, reduce bone resorption, and lower blood glucose levels, thereby achieving the effect of preventing and treating diabetic osteoporosis.

Aural vertigo frequently encountered in the otolaryngology department of traditional Chinese medicine (TCM) mainly involves peripheral vestibular diseases of Western medicine, such as Meniere's disease, benign paroxysmal positional vertigo, vestibular neuritis, and vestibular migraine, being a hot research topic in both TCM and Western medicine. Western medical therapies alone have unsatisfactory effects on recurrent aural vertigo, aural vertigo affecting the quality of life, aural vertigo not relieved after surgery, aural vertigo with complex causes, and children's aural vertigo. The literature records and clinical practice have proven that TCM demonstrates unique advantages in the treatment of aural vertigo. The China Association of Chinese medicine sponsored the "17th youth salon on the diseases responding specifically to TCM: Aural vertigo" and invited vertigo experts of TCM and Western medicine to discuss the difficulties and advantages of TCM diagnosis and treatment of aural vertigo. The experts deeply discussed the achievements and contributions of TCM and Western medicine in the diagnosis and treatment of aural vertigo, the control and mitigation of the symptoms, and the solutions to disease recurrence. The discussion clarified the positioning and advantages of TCM treatment and provided guidance for clinical and basic research on aural vertigo.
