Comprehensive identification of metabolites and metabolic characteristics of luteolin and kaempferol in Simiao Yong'an Decoction in rats by UHPLC-LTQ-Orbitrap MS/MS / 中国中药杂志

Simiao Yong'an Decoction is a classic prescription for treating gangrene. Modern medical evidence has proven that Si-miao Yong'an Decoction has therapeutic effects on atherosclerosis(AS), vascular occlusion angeitides, and hypertension, while its pharmacodynamic mechanism remains unclear. The evidence of network pharmacology, molecular docking, literature review, and our previous study suggests that luteolin and kaempferol are two major flavonoids in Simiao Yong'an Decoction and can inhibit macrophage inflammation and exert anti-AS effects. However, due to lack of the metabolism studies in vivo, little is known about the metabolic characteristics of luteolin and kaempferol. This study employed ultra-performance liquid chromatography coupled with linear ion trap-Orbitrap mass spectrometry(UHPLC-LTQ-Orbitrap MS/MS) and relevant software to identify the metabolites and metabolic pathways of luteolin and kaempferol in rat plasma, urine, and feces, after oral administration of luteolin and kaempferol, respectively. After the administration of luteolin, 10, 11, and 3 metabolites of luteolin were detected in the plasma, urine, and feces, respectively. After the administration of kaempferol, 9, 3, and 1 metabolites of kaempferol were detected in the plasma, urine, and feces, respectively. The metabolic pathways mainly involved methylation, glucuronidation, and sulfation. This study enriches the knowledge about the pharmacological mechanism of luteolin and kaempferol and supplies a reference for revealing the metabolic process of other flavonoids in Simiao Yong'an Decoction, which is of great significance for elucidating the pharmacological effects and effective substances of this decoction in vivo.

ObjectiveTo investigate the short-term efficacy of orthopedic elastic bandages on gait symmetry and walking ability in children with spastic hemiplegic cerebral palsy. MethodsFrom June, 2020 to June, 2023, 31 children with spastic hemiplegic cerebral palsy from Beijing Bo'ai Hospital were randomly divided into control group (n = 15) and experimental group (n = 16). Both groups received routine rehabilitation, while the control group received routine walking training, and the experimental group wore an orthopedic elastic bandage for walking training, for four weeks. The indexes of gait symmetry of foot deviation angle ratio (affected/healthy), step length ratio (affected/healthy), gait line ratio (affected/healthy) and standing stage ratio (affected percentage/healthy percentage) were calculated before and after training, and they were measured step width and the optional and maximum walking speed of 10-meter walk test (10MWT). ResultsOne case dropped off in the experimental group. After training, the foot deviation ratio, step length ratio, gait line ratio, and standing stage ratio improved in both groups (|t| > 2.434, P < 0.05), and they were better in the experimental group than in the control group (|t| > 2.230, P < 0.05); while the optional and maximum walking speed of 10MWT improved in both groups (|t| > 9.186, P < 0.001), and they were better in the experimental group than in the control group (|t| > 2.278, P < 0.05). ConclusionWearing orthopedic elastic bandages during rehabilitation can promote the gait symmetry and walking ability of children with spastic hemiplegic cerebral palsy.

Acupoints compatibility rules of acupuncture for depression disease based on data mining technology / 中国针灸

Based on data mining technology, the acupoints compatibility rules of acupuncture for depression diseases were explored. The randomized controlled trial (RCT) articles regarding acupuncture for depression diseases published from establishment of database to September 2nd, 2022 were searched in CNKI database, Wangfang database, VIP database, SinoMed database, PubMed, EMbase, Web of Science and Cochrane Library. The use frequency of acupoints, meridian tropism, selection of special acupoints and acupoint association rules for five common depression diseases, including primary depression, post-stroke depression, menopausal syndrome, psychoneurosis and anxiety disorder, were analyzed by Python programming language. Cytoscape software was used to analyze the acupoint association and the disease-acupoint co-occurrence network. As a result, totally 387 articles were included, and 319 acupoints prescriptions for the above five common depression diseases were extracted, involving 159 acupoints. The use frequency of acupoints was 2 574 times in total. The frequently-used acupoints were Baihui (GV 20), Sanyinjiao (SP 6), Taichong (LR 3), Neiguan (PC 6), Shenmen (HT 7), Yintang (GV 24+), Zusanli (ST 36), Hegu (LI 4), Sishencong (EX-HN 1) and Taixi (KI 3), etc. The frequently involved meridians were the governor vessel, foot-taiyang bladder meridian, foot-taiyin spleen meridian, and foot-jueyin liver meridian. The frequency of the special acupoints from high to low was crossing points, five-shu points, yuan-primary points, back-shu points, luo-connecting points, and eight confluent points, etc, which were often used in combination with "Baihui (GV 20)-Yintang (GV 24+)" (the highest degree of association). At the same time, the analysis of the co-occurrence network of depression diseases and acupoints showed that the core acupoints group of acupuncture for depression diseases were Baihui (GV 20), Taichong (LR 3), Shenmen (HT 7), Zusanli (ST 36), Neiguan (PC 6) and Sanyinjiao (SP 6). In conclusion, acupuncture treatment for depression diseases has gradually formed a rule of acupoint compatibility, with special acupoint as the main body and "unblocking the governor vessel, and regulating the spirit and qi " as the main therapeutic principle.

Advancements of high-resolution diffusion tensor imaging of brain / 中国介入影像与治疗学

Diffusion tensor imaging (DTI) is an imaging method that can be used to describe changes of tissue structure through the diffusion of water molecules in living tissue. Fiber tracking based on DTI can display the anatomic structure of cerebral nerve fibers noninvasively and clearly, which is of great value for diagnosis and treatment of brain diseases. However, due to the Gaussian hypothesis of the diffusion tensor model, it is difficult to indicate fiber directions in fiber crossing region. A high-resolution DTI method was proposed to estimate the direction distribution of multiple fibers. The research advancements of fiber tracking based on high-resolution DTI were reviewed in this article.

A Comparison of Interside Asymmetries of Lower Extremity Somatosensory Evoked Potentials in Anesthetized Patients with Unilateral Lumbosacral Radiculopathy

STUDY DESIGN: Prospective cohort study. PURPOSE: This study was to investigate interside asymmetries of three lower extremity somatosensory evoked potentials (SSEPs) in anesthetized patients with unilateral lumbosacral radiculopathy. OVERVIEW OF LITERATURE: Although interside asymmetry is an established criterion of abnormal SSEP, little is known which of the lower SSEPs is more sensitive in detecting interside asymmetry in anesthetized patients. METHODS: Superficial peroneal nerve SSEP (SPN-SSEP), posterior tibial nerve SSEP (PTN-SSEP), and sural nerve SSEP were obtained in 31 lumbosacral surgery patients with unilateral lumbosacral radiculopathy, and compared with a group of 22 control subjects. RESULTS: The lumbosacral group showed significant larger interside asymmetry ratios of P37 latencies in SPN-SSEP and PTN-SSEP, and significant larger interside asymmetry ratio of P37-N45 amplitude in SPN-SSEP, when comparing with the control group. Within the lumbosacral group but not the control group, SPN-SSEP displayed significant larger interside asymmetry ratio in P37 latency. When referencing to the control group, more patients in the lumbosacral group displayed abnormal interside SPN-SSEP latency asymmetries which corroborated the symptom laterality. CONCLUSIONS: The data suggested that SPN-SSEP was more sensitive in detecting interside latency asymmetry in anesthetized patients.

The contraction times of rectus abdominis and back extensors were recorded and ana-lyzed. Results The reaction time and movement time were shorter, and the contraction rates of rectus abdominis and back extensors were lower in the degree with-15° than with 0° and 15° (P0.05), and the movement time was longer in the patients group than in the control group (P<0.001). The contraction rates were higher in the patients group than in the control group. Conclusion Anterior tilted seat surface may improve the front protraction function of upper limb and the postural adjustment in children with cerebral palsy.

Effect of exercise on estrogen deficiency-induced depression-like behavior and its inflammatory mechanisms / 第二军医大学学报

Objective To explore whether exercise training can ameliorate estrogen deficiency-induced depression-like behavior and its mechanisms, so as to provide evidence for treating menopausal depression with exercise. Methods A total of 60 female adult C57BL/6J mice were randomly assigned to Sham-sedentary (Sham), Sham-exercise (Sham+Ex), Ovx-sedentary (Ovx) and Ovx-exercise (Ovx+Ex) groups. Sham operation or bilateral Ovx was performed. After recovery for 1 week, Sham+ Ex and Ovx+Ex mice were adapted to the treadmill for 5 weeks. We use sucrose consumption test, open field test and tail suspension test to inspect the mice of behavior change; then the mice were decapitated, and the serum and hippocampus samples were collected. 5-hydroxytryptamine (5-HT), indoleamine 2, 3-dioxygenase (IDO) and inflammatory cytokine in the hippocampus were determined using a commercial ELISA kit. Results Compared with Sham mice, Ovx mice developed depression-like behaviors, including loss of interests, decreased exploratory behavior and increased behavioral despair, and exercise training could ameliorate these depression-like behaviors. Compared with the Sham group, Ovx group had significantly decreased hippocampal 5-HT level (P<0. 01) and significantly increased IDO level (P<0. 05) in the hippocampus, which were reversed by exercise training. The hippocampal levels of proinflammatory cytokines, IL-1" (P<0. 05), IL-6 (P<0. 01) and IFN-y (P<0. 01) in Ovx group were significantly increased compared to Sham mice, while the anti-inflammatory cytokines, IL-4 (P<0. 01) and IL-10 (P<0. 05), were significantly decreased in Ovx mice; exercise training could also reverse the alterations of IL1", IFN-y and IL-4 levels in Ovx mice. Conclusion Exercise training can ameliorate estrogen deficiency-induced depression-like behaviors, which may be through improving inflammation in the hippocampus.
