ObjectiveTo study the marketed products and prescription characteristics of Chinese patent medicines for rheumatoid arthritis （RA） in China， thus providing support for clinical application and innovative research and development of Chinese patent medicines for RA. MethodsInformation on marketed Chinese patent medicines for RA treatment was collected. Preliminary data organization and statistical analysis were performed in Microsoft Excel 2021. Subsequently， the standardized prescriptions were analyzed via the Ancient and Modern Medical Case Cloud Platform （V2.3.9） across dimensions including medicinal properties， flavors， channel tropisms， usage characteristics， and formulation patterns. ResultsThis study ultimately included 311 marketed Chinese patent medicines for RA in China. Their initial market launch dates were mostly concentrated from the 1990s to the early 21st century. The National Basic Medical Insurance， Work-Related Injury Insurance， and Maternity Insurance Drug Directory included 89 Chinese patent medicines for RA. The primary dosage forms were tablets， capsules， medicated wines， and pills. After screening， 237 prescriptions were obtained， and the research on their origins was lagging. Among them， the Chinese patent medicines for treating wind-cold-dampness obstruction syndrome accounted for the highest proportion. The top three most frequently used medicinals were Angelicae Sinensis Radix， Notopterygii Rhizoma et Radix， and Saposhnikoviae Radix. Medicinal properties were primarily warm and plain， and flavors were mostly pungent， sweet， and bitter. The medicinals predominantly exhibited the liver and spleen channel tropism. Association rule analysis revealed that the herb pairs with the highest confidence were Chuanxiong-Angelicae Sinensis Radix and Myrrha-Olibanum. Cluster analysis yielded three medicinal combinations. ConclusionAlthough Chinese patent medicines for RA have application advantages， issues such as narrow syndrome coverage and insufficient innovation in dosage forms exist. Future development should focus on constructing an evidence-based system， strengthening the textual research on prescription origins and the exploration of classical famous formulas， and promoting dosage form innovation and precise medication to enhance their clinical value.

ObjectiveTo investigate the effects of Liuwei Dihuangwan on mammalian target of rapamycin （mTOR）-mediated synaptic plasticity in the prefrontal cortex-hippocampus circuit in the rat model of valproic acid （VPA）-induced autism spectrum disorder （ASD） and to explore its potential mechanism for reducing behavioral abnormalities in ASD rats. MethodsThirteen SD pregnant rats were randomized into the VPA group （10 rats） and the control group （3 rats）. On gestational day 13， the VPA group was intraperitoneally injected with VPA solution （600 mg·kg^-1）， while the control group was injected with an equal volume of normal saline. Male pups of 21 days old from both groups underwent behavioral tests to screen the ASD model rats （32 rats）. These rats were then randomly assigned to the model （distilled water）， vitamin D （1 480 U·kg^-1）， low-dose （0.75 g·kg^-1） Liuwei Dihuangwan， and high-dose （1.5 g·kg^-1） Liuwei Dihuangwan groups， and normal male pups were selected as the blank group （distilled water）， with 8 rats in each group. Each group was treated with the corresponding drug or an equal volume of distilled water via gavage daily. After drug administration， behavioral tests were conducted again， followed by anesthesia and tissue collection. Nissl staining was carried out to observe the morphological changes of neurons in the prefrontal cortex and hippocampus. Transmission electron microscopy was used to observe changes in hippocampal synaptic structure. Immunohistochemistry and Western blot were employed to determine the expression of mTOR， phosphatidylinositol 3-kinase （PI3K）， and protein kinase B （Akt） in the prefrontal cortex， as well as synaptophysin-1 （SYP-1）， postsynaptic density 95 （PSD95）， and N-methyl-D-aspartate receptors （NMDARs） in the hippocampus. ResultsCompared with the control group， the model group exhibited severe growth retardation and developmental deformities， with abnormal behavioral performance and pathological damage to neurons and synapses in the prefrontal cortex and hippocampus. Compared with the model group， all treatment groups showed reduced behavioral abnormalities and pathological damage to neurons and synapses in the prefrontal cortex and hippocampus， with the most significant effects in the high-dose Liuwei Dihuangwan group. Immunohistochemistry and Western blotting results showed that compared with the control group， the model group exhibited significantly increased protein levels and phosphorylation ratios of p-mTOR， p-Akt， and p-PI3K in the prefrontal cortex （P<0.05， P<0.01）， and decreased protein levels of SYP-1 and PSD95 and increased protein level of NMDARs in the hippocampus （P<0.01）. Compared with those in the model group， the protein levels of p-mTOR， p-Akt， and p-PI3K in the prefrontal cortex decreased in the vitamin D and high-dose Liuwei Dihuangwan groups （P<0.05）， and the p-mTOR/mTOR， p-Akt/Akt， and p-PI3K/PI3K ratios in the prefrontal cortex declined in the vitamin D group （P<0.05）. The high-dose Liuwei Dihuangwan group showed a reduction in p-PI3K/PI3K ratio （P<0.05）. The protein level of SYP-1 and PSD95 in the hippocampus increased in the vitamin D， low-dose Liuwei Dihuangwan， and high-dose Liuwei Dihuangwan groups （P<0.05， P<0.01）， while the protein level of NMDARs decreased in the vitamin D and high-dose Liuwei Dihuangwan groups （P<0.01）. ConclusionLiuwei Dihuangwan significantly reduces VPA-induced ASD-like behaviors and enhances the regeneration and repair of neurons in the prefrontal cortex and synaptic structures in the hippocampus by downregulating of PI3K/Akt/mTOR expression in the prefrontal cortex， upregulating SYP-1 and PSD95 expression in the hippocampus， and inhibiting NMDARs expression.

OBJECTIVE: To investigate the effectiveness of hip arthroscopy in the treatment of patients with femoroacetabular impingement (FAI) syndrome combined with ligamentum teres injury. METHODS: A retrospective analysis was conducted on 23 patients (23 hips) with Cam-type FAI syndrome combined with ligamentum teres injury who met the selection criteria between April 2022 and May 2024. The cohort included 12 males and 11 females, with a mean age of 29.16 years (range, 16-57 years). According to Tönnis classification, there were 5 cases of grade 0, 10 cases of grade Ⅰ, and 8 cases of grade Ⅱ in hip osteoarthritis. The disease duration ranged from 6 to 24 months, with an average of 12 months. Under hip arthroscopy, hypertrophic synovium and the damaged ligamentum teres were debrided, while the torn labrum and cartilage were repaired, and femoral head-neck osteoplasty was performed to eliminate impingement, restore the normal morphology of the acetabulum and femoral head-neck, and suture the joint capsule. Acetabular lateral center-edge angle (LCEA) and α angle (reflecting the degree of non-sphericity at the femoral head-neck junction) were measured before and after operation, and the modified Harris hip score (mHHS), the International Hip Outcome Tool-12 (IHOT-12), and the visual analogue scale (VAS) score for pain were evaluated. RESULTS: The operation was successfully completed in all patients. The incisions healed by first intention after operation, and there was no perioperative complications such as iatrogenic cartilage injury, fracture, infection, neurovascular traction injury, or lower extremity venous thrombosis. All the 23 patients were followed up 12-24 months, with an average of 14.6 months. The pain of hip joint significantly relieved, and the function of hip joint improved; no complication such as joint stiffness, joint instability, and osteonecrosis of the femoral head occurred. The α angle, VAS score, mHHS score, and IHOT-12 score at last follow-up were significantly better than those before operation ( P<0.05); there was no significant difference in LCEA compared to preoperative value ( P>0.05). CONCLUSION Hip arthroscopy is a safe and effective treatment for patients with FAI syndrome combined with ligamentum teres injury, which can achieve satisfactory effectiveness.

Objective:To explore the relationship between autistic trait and pain empathy among college students, as well as the mediating role of personal pain perception.Methods:From October to December 2023, a cross-sectional survey was conducted among 1 195 college students using the autism spectrum quotient, pain sensitivity questionnaire, fear of pain questionnaire, pain catastrophizing scale and empathy for pain scale.SPSS 27.0 software was used for descriptive statistics and correlation analysis.A structural equation model was constructed using Mplus 8.3 to examine the mediating effect of personal pain perception, which was composed of pain sensitivity, fear and catastrophizing cognition.Results:Autistic trait(22.00(18.00, 26.00))was significantly positively correlated with pain sensitivity (55.00(43.00, 70.00)), fair of pain (69.00(60.00, 78.00)), and pain catastrophizing cognition (16.00(8.00, 23.00)) ( r=0.112, 0.154, 0.204, all P<0.001).Autistic trait was also significantly positively correlated with affective distress(62.00(46.00, 80.00), r=0.162, P<0.001) and vicarious pain (14.00(8.00, 20.00), r=0.096, P<0.001) of pain empathy.Pain sensitivity, fear of pain and pain catastrophizing cognition were significantly positively correlated with affective distress( r=0.244, 0.332, 0.375, all P<0.001) and vicarious pain ( r=0.210, 0.232, 0.285, all P<0.001) of pain empathy.The effects of autistic trait on affective distress and vicarious pain dimensions of pain empathy were fully mediated by personal pain perception, with the mediating effects of 0.115( P<0.001, 95% CI=0.073-0.165) and 0.085( P<0.001, 95% CI=0.053-0.124). Conclusions:The autistic trait of college students can predict the affective distress and vicarious pain of pain empathy indirectly through personal pain perception.

Objective In this study,exogenous hormones combined with variable temperature stratification were used to relieve seed dormannia of Coptis chinensis and promote seed germination,and the effects of gibberellin on the physiological,biochemical and embryonic morphological changes of C.chinensis seeds during post-mature germination were further evaluated.Methods Using orthogonal test,different exogenous hormones(GA3,6-BA,NAA,ABA)and different temperature changing stratification(20℃/4℃)were set up,and the germination index(germination rate and split rate)of C.chinensis seeds were statistically compared.The activity of antioxidant enzymes(peroxidase POD,catalase CAT),the content of malondialdehyde(MDA)and endogenous hormones(GA,IAA,ABA)during the germination of C.chinensis seeds under optimal treatment were measured.The microscopic structure of the seeds was observed by paraffin embedding section.Results The results of range analysis showed that the best budding method was:100 mg·L-1 of gibberellin for 12 h,20℃for 60 day,4℃for 10 day.Physiological and biochemical index analysis showed that 100 mg·L-1 exogenous gibberellin treatment promoted the endogenous GA content to reach the peak in advance,maintained the POD and CAT contents at a higher level,and maintained the malondialdehyde(MDA)content at a lower level.The transformation from torpedo embryo to cotyledonous embryo was observed by electron microscope during postmature germination.Conclusion Exogenous gibberellin combined with variable temperature stratification treatment could significantly accelerate seed germination of C.chinensis,mainly by promoting seed embryo morphological development,affecting the contents of GA,POD and CAT,and rapidly relieving seed dormancy to promote seed germination.Compared with natural conditions,the germination period could be shortened by about six months.

In recent years, survival rate of patients with severe brain injury has been improved with the development of emergency care skills, yet disorders of consciousness (DoC) patients still have poor outcome and need prolonged life support, burdening the families and society. There are still deficiencies in precise diagnosis, individualized treatment and end-of-life decision-making. Based on this, we give the following propositions: promoting multimodal assessment to reduce misdiagnosis; developing individualized plans based on assessment results, stratifying and managing patients at acute or chronic phases, classifying and managing patients with different consciousness levels, improving the legal and ethical framework, scientifically assessing end-of-life decisions, and implementing comprehensive care with multidisciplinary collaboration to enhance DoC patients' quality of life.
