This study explored the potential therapeutic targets and mechanisms of Danggui Shaoyao San(DSS) in the prevention and treatment of Alzheimer's disease(AD) through transcriptomics and metabolomics, combined with animal experiments. Fifty male C57BL/6J mice, aged seven weeks, were randomly divided into the following five groups: control, model, positive drug, low-dose DSS, and high-dose DSS groups. After the intervention, the Morris water maze was used to assess learning and memory abilities of mice, and Nissl staining and hematoxylin-eosin(HE) staining were performed to observe pathological changes in the hippocampal tissue. Transcriptomics and metabolomics were employed to sequence brain tissue and identify differential metabolites, analyzing key genes and metabolites related to disease progression. Reverse transcription-quantitative polymerase chain reaction(RT-qPCR) was employed to validate the expression of key genes. The Morris water maze results indicated that DSS significantly improved learning and cognitive function in scopolamine(SCOP)-induced model mice, with the high-dose DSS group showing the best results. Pathological staining showed that DSS effectively reduced hippocampal neuronal damage, increased Nissl body numbers, and reduced nuclear pyknosis and neuronal loss. Transcriptomics identified seven key genes, including neurexin 1(Nrxn1) and sodium voltage-gated channel α subunit 1(Scn1a), and metabolomics revealed 113 differential metabolites, all of which were closely associated with synaptic function, oxidative stress, and metabolic regulation. RT-qPCR experiments confirmed that the expression of these seven key genes was consistent with the transcriptomics results. This study suggests that DSS significantly improves learning and memory in SCOP model mice and alleviates hippocampal neuronal pathological damage. The mechanisms likely involve the modulation of synaptic function, reduction of oxidative stress, and metabolic balance, with these seven key genes serving as important targets for DSS in the treatment of AD.

OBJECTIVE: To evaluate the clinical efficacy of "Shibao Decoction" in the management of late-onset hypogonadism (LOH) caused by deficiency of kidney essence. METHODS: Sixty male patients with late-onset hypogonadism of kidney essence deficiency type were randomly assigned to the treatment group and the control group, each with 30 cases. The patients in treatment group were treated with oral Shibao Decoction, while the control group was treated with oral Testosterone Undecanoate Capsules. The patients in both groups were treated for 12 weeks. The PADAM symptom score, TCM syndrome score, serum total testosterone (TT), serum free testosterone (FT), sex hormone binding globulin (SHBG), body mass index (BMI), total skeletal muscle mass index (SMI), appendicular skeletal muscle mass index (ASMI), FBG, FINS, and insulin resistance index (HOMA-IR) levels were compared between the two groups. RESULTS: After treatment, PADAM scores for each item and TCM symptoms score decreased, TT and FT increased in both groups, all with statistically significant differences from those of pre-treatment (P<0.05). The level of SHBG in the control group decreased (P<0.05), which had not changed significantly in the treatment group (P>0.05). After treatment, SMI and ASMI increased in both groups significantly (P<0.05). BMI decreased in the control group (P<0.05), which had not changed significantly in the treatment group (P>0.05). The level of FINS decreased in the control group (P<0.05), which had not changed significantly in the treatment group (P>0.05). FPG had not changed significantly in both groups (P>0.05), and the insulin resistance index (HOMA-IR) had significantly improved in both groups, all with statistically significant differences from those of pre-treatment (P<0.05). After treatment, the total effective rates of PADAM score and TCM syndrome score in the treatment group were 73.3% and 86.6% respectively, and the total effective rates in the control group were 66.7% and 76.6% respectively. The total effective rates of the two scores in the treatment group were slightly higher than those in the control group (P>0.05). There was no significant difference in the indicators between the two groups after treatment, and the treatment group is generally comparable with the control group in the therapeutic effects (P>0.05). And no adverse reactions occurred during treatment in both groups. CONCLUSION The "Shibao Decoction" has a remarkable therapeutic effect on late-onset hypogonadism caused by deficiency of kidney essence and has good safety. It can be used as an alternative to testosterone undecanoate and is worthy of clinical promotion and application.

Anxiety disorder is a major symptom of autism spectrum disorder (ASD) with a comorbidity rate of ~40%. However, the neural mechanisms of the emergence of anxiety in ASD remain unclear. In our study, we found that hyperactivity of basolateral amygdala (BLA) pyramidal neurons (PNs) in Shank3 InsG3680 knock-in (InsG3680^+/+) mice is involved in the development of anxiety. Electrophysiological results also showed increased excitatory input and decreased inhibitory input in BLA PNs. Chemogenetic inhibition of the excitability of PNs in the BLA rescued the anxiety phenotype of InsG3680^+/+ mice. Further study found that the diminished control of the BLA by medial prefrontal cortex (mPFC) and optogenetic activation of the mPFC-BLA pathway also had a rescue effect, which increased the feedforward inhibition of the BLA. Taken together, our results suggest that hyperactivity of the BLA and alteration of the mPFC-BLA circuitry are involved in anxiety in InsG3680^+/+ mice.

BACKGROUND:Interspinous distraction fusion device BacFuse was used for the management of lumbar degenerative disease and obtained good clinical efficacy in recent years.However,the related biomechanical study was lacking. OBJECTIVE:To explore the related biomechanical characteristics of BacFuse,a novel interspinous distraction fusion device,which was used in lumbar degenerative disease. METHODS:After constructing the goat spinal models(L1-L6),they were grouped into four groups based on different simulated surgeries:the control group,the BacFuse group(L3/4),the screw-rod fixation group(L3/4)and the Topping-off group(L3/4 screw-rod fixation + L2/3 BacFuse fixation).The goat lumbar spine surgical model was assembled into a biomechanical testing system.A biomechanical machine was used for mechanical loading,simulating lumbar spine movement of flexion,extension,lateral flexion and rotation with a 4 Nm moment.A visual tracking system was used for positioning and capturing.Finally,mechanical and optical calibration was completed to calculate the range of motion of the L2/3,L3/4 and L4/5 segments. RESULTS AND CONCLUSION:(1)Compared with the control group,the range of motion of the L3/4 segment in the BacFuse group decreased 27.27%,70%,38.1%and 23.08%in the flexion,extension,lateral bending and rotation directions,respectively(P<0.05).The range of motion of L3/4 segment in the screw-rod fixation group decreased 72.73%,80%,71.43%and 73.08%in the flexion,extension,lateral bending and rotation directions,respectively(P<0.05).(2)Compared with the control group,the range of motion of the adjacent segment L2/3 increased by 33.33%,25%and 23.81%in the extension,lateral bending and rotation directions,respectively in the BacFuse group(P<0.05),with no significant change in flexion.In the screw-rod fixation group,there was a 50%,44.44%,50%and 58.96%increase in the adjacent segment L2/3 in the flexion,extension,lateral calibration and rotation directions,respectively(P<0.05).(3)Compared with the control group,the BacFuse group showed an increase in range of motion in proximal segment L4/5 in the extension and rotation directions by 27.3%and 17.39%(P<0.05)respectively,with no significant change in flexion or lateral bending.In the screw-rob fixation group,the proximal segment L4/5 demonstrated 38.89%,22.73%and 26.09%(P<0.05)increases in range of motion in the flexion,extension and rotation directions,respectively,with no significant change in lateral bending.(4)In the Topping-off group,the range of motion of L2/3 was reduced by 37.04%,73.08%,56.67%and 38.46%in flexion,extension,lateral flexion and rotation,respectively,compared to the screw-rob fixation group(P<0.05).Compared with the screw-rob fixation group,the Topping-off group showed a 20%reduction in the range of motion of the L4/5 in the flexion direction(P<0.05),with no significant differences seen in extension,lateral bending and rotation.(5)It is concluded that the interspinous distraction fusion device BacFuse significantly reduces the range of motion of the implanted segment and provides some stability.It still retains more mobility and reduces the impact on the adjacent segment compared to screw-rob fixation,while the Topping-off tip,which can be used for intervertebral fusion fixation,significantly reduces the range of motion of the adjacent segment and reduces the risk of adjacent segment degeneration.

The incidence of osteoporotic thoracolumbar vertebral fracture (OTLVF) in the elderly is gradually increasing. The kyphotic deformity caused by various factors has become an important characteristic of OTLVF and has received increasing attention. Its clinical manifestations include pain, delayed nerve damage, sagittal imbalance, etc. Currently, the definition and diagnosis of OTLVF with kyphotic deformity in the elderly are still unclear. Although there are many treatment options, they are controversial. Existing guidelines or consensuses pay little attention to this type of fracture with kyphotic deformity. To this end, the Lumbar Education Working Group of the Spine Branch of the Chinese Medicine Education Association and Editorial Committee of Chinese Journal of Trauma organized the experts in the relevant fields to jointly develop Clinical guidelines for the diagnosis and treatment of osteoporotic thoracolumbar vertebral fractures with kyphotic deformity in the elderly ( version 2024), based on evidence-based medical advancements and the principles of scientificity, practicality, and advanced nature, which provided 18 recommendations to standardize the clinical diagnosis and treatment.

Objective:To explore interspinous fusion capacity after interspinous distraction fusion (ISDF) device implantation, a preliminary biomechanical analysis and histological evaluation were performed.Methods:The experimental animals were procured from the Science and Research Laboratory Animal Center of Beijing Friendship Hospital, Capital Medical University. The animals were 8-9 weeks old and with an average weight of 25 kg. 15 mini-pigs were randomly divided into three groups, the sham operation group, the decompression group and the ISDF fixed decompression group, 5 animals per group. The sham operation group was treated with simple incision and exposed lamina suture. The decompression group received unilateral decompression and the ISDF fixed decompression group experienced unilateral hemilaminectomy decompression and ISDF fixation. The graft-bed site was filled with purified bone graft material without any autograft bone. After 6 months feeding, all experimental animals were sacrificed and the corresponding lumbar vertebrae was obtained. The samples were fixed on the spinal test system and the range of motion of flexion-extension, lateral bending and rotation were tested through a multiaxial robotic system. The ISDF device samples were embedded for hard tissue sections and stained with hematoxylin-eosin and toluidine blue to assess new bone formation. Normally distributed measurement data were expressed as mean±standard deviation( ± s), and independent samples t-test were used for comparisons between groups. Results:In comparison to the sham operation group, the decompression group exhibited a statistically significant increase in intervertebral mobility, with an average of 61.6% in anterior flexion, 44.7% in posterior extension, 65.0% in left lateral flexion, 49.6% in right lateral flexion, 83.8% in left rotation, and 64.2% in right rotation ( P<0.05). In comparison to the decompression group, the ISDF fixed decompression group exhibited a statistically significant decrease in intervertebral mobility, with an average of 40.0% in anterior flexion, 21.3% in posterior extension, 31.7% in left lateral flexion, 22.3% in right lateral flexion, 28.7% in left rotation, and 35.3% in right rotation ( P<0.05). Well-defined bone tissue can be observed in the histological images of ISDF fixed decompression group samples after 6 months. In the histological part, toluidine blue staining showed extensive new bone formation. The hyperchromatic osteoblasts cells and density bone tissue can be observed in hematoxylin-eosin staining slides. Conclusions:The implantation of ISDF provide the necessary stabilization for promoting fusion. The osteogenesis that occurs within graft-bed site of the ISDF device offers the possibility of interspinous fusion.
