Enhancing Idiopathic Scoliosis Patients' Outcomes Through Functional Rehabilitation Training in Combination with Orthosis.

Objective: This study aims to provide clinical evidence for the treatment of idiopathic scoliosis (IS) by assessing the therapeutic effectiveness of combining functional rehabilitation training with orthosis. Methods: We enrolled a total of 94 IS patients who were admitted to our hospital from April 2020 to February 2022. These patients were randomly assigned into two groups: a research group (RG; n=47) receiving functional rehabilitation training combined with orthosis and a control group (CG; n=47) receiving orthosis treatment alone. Clinical outcomes were evaluated one year after treatment. We also measured the Cobb angle, apical vertebral rotation (AVR), and the distance between the vertical line of the sacrum and the spinous process of the scoliosis parietal vertebra before and after treatment to determine apical vertebral translation (AVT) from the sacral midline and lumbar range of motion (ROM). Patient quality of life was assessed using the Short-Form 36 Item Health Survey (SF-36). Results: After treatment, the research group exhibited significantly lower Cobb angles, AVR, and AVT, along with a higher overall response rate and greater lumbar ROM compared to the control group (P < .05). Post-treatment SF-36 scores increased in both groups, with notably higher scores in the research group (P < .05). Conclusions: Combining functional rehabilitation training with orthosis is an effective approach for the treatment of IS and holds substantial clinical significance.

Integrative evaluation of primary and metastatic lesion spectrum to guide anti-PD-L1 therapy of non-small cell lung cancer: results from two randomized studies.

Objectives: Clinical benefits of immune-checkpoint blockade (ICB) versus standard chemotherapy have been established in unselected non-small cell lung cancer (NSCLC). However, the response to ICB therapy among patients is heterogeneous in clinical practice. Materials and Methods: We retrospectively assessed the predicitive effect of the primary and metastatic lesion spectrum (baseline sum of the longest diameters [SLD], number of metastatic sites and specific organ metastases) on the efficacy of atezolizumab over docetaxel in OAK and POPLAR trial cohorts. A decision model, termed DSO (Diameter-Site-Organ), based on the spectrum was developed and validated for guiding ICB. Results: Higher SLD (>38 mm) and more metastatic sites (≥2) were characterized with pronounced overall survival (OS) benefits from atezolizumab versus docetaxel. Specifically, adrenal gland and brain metastases were identified as favorable predictors of atezolizumab treatment. The DSO model was developed in the discovery cohort to integrate the directive effect of the primary and metastatic lesion spectrum. Remarkably, a general pattern of enhanced efficacy of atezolizumab versus docetaxel was observed along with the increase of the DSO score. For patients with DSO score > 0, atezolizumab yielded a significantly prolonged OS than docetaxel, whereas OS was generally similar between two treatments in patients with DSO score ≤ 0. Equivalent findings were also seen in the internal and external validation cohorts. Conclusions: The response to anti-PD-L1 therapy among patients varied with the primary and metastatic lesion spectrum. The DSO-based system might provide promising medication guidance for ICB treatment in NSCLC patients.

Herbal Formula Fo Shou San Attenuates Alzheimer's Disease-Related Pathologies via the Gut-Liver-Brain Axis in APP/PS1 Mouse Model of Alzheimer's Disease.

Fo Shou San (FSS) is an ancient paired-herb decoction, used in China to treat blood deficiency, blood stasis, stroke, and ischemic cerebral vascular disease for about one thousand years. The mechanisms associated with these properties, however, are not completely understood. Gut bacteria, gut bacterial lipopolysaccharides (LPS), alkaline phosphatase (AP), and lipid peroxidation are common biochemical signaling that takes place on gut-liver-brain axis. Growing evidences have revealed that gut bacterial lipopolysaccharides (LPS) enter the systemic circulation via the portal vein, and finally entering the brain tissue is an important cause of inflammatory degeneration of Alzheimer's disease (AD). Alkaline phosphatase (AP) dephosphorylates LPS forming a nontoxic LPS and reduces systemic inflammation via gut-liver-brain axis. In this study, to identify the differentially gut-liver-brain axis among APP/PS1 mice, FSS-treated APP/PS1 mice, and control mice, behavioral tests were performed to assess the cognitive ability and hematoxylin-eosin staining was used to assess neuronal damage in the hippocampus; immunohistochemistry, western blotting, a quantitative chromogenic end-point Tachypleus amebocyte lysate (TAL) assay kit, Malondialdehyde (MDA) assay kit, AP Assay Kit, and real-time quantitative PCR (qPCR) were used to assess the level of LPS, MDA, AP, and gut bacteria. We found that FSS regulates gut-liver-brain axis to regulate AP and gut bacteria and attenuate the LPS-related systemic inflammation, oxidative stress (MDA), and thereby AD-related pathology in APP/PS1 mice. This is the first study to provide a reference for FSS-treated AD mice to aid in understanding the underlying mechanisms of FSS. FSS may also improve gastrointestinal tract barrier and blood-brain barrier and thus ameliorates the symptoms of AD; this is subject to our further study.

Eugenol inhibits non-small cell lung cancer by repressing expression of NF-κB-regulated TRIM59.

In view of the recognized anti-tumor properties of eugenol against non-small cell lung cancer (NSCLC) in cell culture, here we further set out to investigate the potential therapeutic effect of eugenol in vivo and elucidate the underlying molecular mechanism. The relative expression levels of TRIM59 and p65 in NSCLC were quantified by real-time polymerase chain reaction. Xenograft tumor model was established with TRIM59-deficient H1975 cells, and tumor progression was monitored. Kaplan-Meier's analysis was performed to measure overall survival. Protein levels of TRIM59 and p65 in xenograft tumor were determined by western blot. Direct binding of p65 on the TRIM59 promoter was analyzed by chromatin immunoprecipitation assay, and the regulatory effect was interrogated with luciferase reporter assay. Both TRIM59 and p65 were up-regulated in NSCLC. Eugenol treatment significantly inhibited xenograft tumor progression and prolonged the overall survival of tumor-bearing mice. Mechanistically, eugenol suppressed p65 expression, which subsequently decreased TRIM59 expression. TRIM59 deficiency fully recapitulated the anti-tumoral phenotype elicited by eugenol. Ectopic expression of TRIM59 completely abolished the tumor suppressive effect of eugenol, which underlined the predominant role of TRIM59 in mediating the signaling downstream of eugenol treatment. Eugenol inhibited NSCLC via repression NF-κB-TRIM59 pathway.

Ginsenoside Rg1 Attenuates Cigarette Smoke-Induced Pulmonary Epithelial-Mesenchymal Transition via Inhibition of the TGF-ß1/Smad Pathway.

Epithelial-mesenchymal transition (EMT) is a process associated with airway remodeling in chronic obstructive pulmonary disease (COPD), which leads to progressive pulmonary destruction. Panax ginseng is a traditional herbal medicine that has been shown to improve pulmonary function and exercise capacity in patients with COPD. Ginsenoside Rg1 is one of the main active components and was shown to inhibit oxidative stress and inflammation. The present study investigated the hypothesis that ginsenoside Rg1 attenuates EMT in COPD rats induced by cigarette smoke (CS) and human bronchial epithelial (HBE) cells exposed to cigarette smoke extract (CSE). Our data showed that CS or CSE exposure increased expression of the mesenchymal marker α-smooth muscle actin (α-SMA) and decreased expression of the epithelial marker epithelial cadherin (E-cad) in both lung tissues and HBE cells, which was markedly suppressed by ginsenoside Rg1. Importantly, CS-induced upregulation of TGF-ß1/Smad pathway components, including TGF-ß1, TGF-ßR1, phospho-Smad2, and phospho-Smad3, was also inhibited by ginsenoside Rg1. Additionally, ginsenoside Rg1 mimicked the effect of SB525334, a TGF-ßR1-Smad2/3 inhibitor, on suppression of EMT in CSE-induced HBE cells. Collectively, we concluded that ginsenoside Rg1 alleviates CS-induced pulmonary EMT, in both COPD rats and HBE cells, via inhibition of the TGF-ß1/Smad pathway.

Sensitive UHPLC-MS/MS quantitation and pharmacokinetic comparisons of multiple alkaloids from Fuzi- Beimu and single herb aqueous extracts following oral delivery in rats.

Aconiti Lateralis Radix Praeparata- Fritillariae Thunbergii bulbus, namely Fuzi- Beimu in Chinese, is a classic herb pair whose combined administration was prohibited according to the rule of "Eighteen antagonisms". However, incompatibility of Fuzi and Beimu has become controversial because of the application supported by many recorded ancient prescriptions and increasing modern researches and clinical practice. The present study aimed to investigate the pharmacokinetic differences of multiple alkaloids from Fuzi- Beimu and the single herb aqueous extracts following oral delivery in rats. Twelve alkaloids including aconitine, mesaconitine, hypaconitine, benzoylaconitine, benzoylmesaconitine, benzoylhypacoitine, neoline, fuziline, talatisamine, chasmanine, peimine and peimisine in rat plasma were simultaneously quantitated by using sensitive ultra-high performance liquid chromatography- tandem mass spectrometry (UHPLC-MS/MS), with the method developed and fully validated. Plasma concentrations of the twelve alkaloids after administration were determined and pharmacokinetic parameters were compared. Significant differences were observed for all alkaloids except aconitine, mesaconitine and benzoylaconitine for Fuzi- Beimu group in comparison with the single herb group. AUC0-t and T1/2 of hypaconitine were increased significantly. AUC0-t and Cmax were increased and Tmax decreased significantly for benzoylmesaconitine and benzoylhypacoitine. Fuziline showed significantly increased AUC0-t, Cmax and Tmax. T1/2 of neoline was notably increased. T1/2 and Tmax were significantly elevated for talatisamine while Cmax decreased. Tmax of chasmanine was significantly increased and Cmax decreased. Extremely significant increase of Tmax was found for peimisine, and significant increase of T1/2 for peimine. Results revealed that combined use of Fuzi and Beimu significantly influenced the system exposure and pharmacokinetic behaviors of multiple alkaloids from both herbs, indicating herb- herb interaction between Fuzi and Beimu.

Validation of biomarkers in cardiotoxicity induced by Periplocin on neonatal rat cardiomyocytes using UPLC-Q-TOF/MS combined with a support vector machine.

Corex Periplocae (the root of Periploca sepium Bge) has been widely used in clinics. Periplocin, as one of the components of cardiac glycosides in Corex Periplocae, easily triggers cardiotoxicity when used improperly. To evaluate the toxicity of Periplocin, we used UPLC-Q-TOF/MS to investigate metabolic profiles on neonatal rat cardiomyocytes exposed to high and low doses of Periplocin (0.2 mmol/L, 0.4 mmol/L). Finally, we identified 11 biomarkers associated with toxicity through multivariate statistical analysis. A "supervised" Support Vector Machine (SVM) study was used to optimize and verify the reliability of these biomarkers. In these biomarkers, all biomarkers, including carnitine, acetylcarnitine, lysoPC(16:0), proline, glutamic acid, pyroglutamic acid, leucine, pantothenic acid, tryptophan, indoleacrylic acid and citric acid, revealed a downward trend with the increase of dosage. Moreover, pathway analysis showed that these metabolites were associated with amino acid metabolism, energy metabolism and sphingolipid metabolism, which contributes to a further understanding of the toxicity mechanism of Corex Periplocae and its clinical safety. Additionally, we demonstrate that an UPLC-Q-TOF/MS-based metabolomic approach is a powerful tool and provides a promising approach for assessing the toxicity of traditional Chinese medicine and drug safety screening.

A GC-MS Based Metabonomics Study of Rheumatoid Arthritis and the Interventional Effects of the Simiaowan in Rats.

Simiaowan (SMW) is a famous Chinese prescription widely used in clinical treatment of rheumatoid arthritis (RA). The aim of the present study is to determine novel biomarkers to increase the current understanding of RA mechanisms, as well as the underlying therapeutic mechanism of SMW, in RA-model rats. Plasma extracts from control, RA model, and SMW-treated rats were analyzed by gas chromatography coupled with mass spectrometry (GC-MS). An orthogonal partial least-square discriminant analysis (OPLS-DA) model was created to detect metabolites that were expressed in significantly different amounts between the RA model and the control rats and investigate the therapeutic effect of SMW. Metabonomics may prove to be a valuable tool for determining the efficacy of complex traditional prescriptions.

Gas chromatography-mass spectrometry and high-performance liquid chromotagraphy analysis of the drug absorption characteristics in the buccal mucosa via a circulating device.

The aim of the present study was to investigate the characteristics of Su Xiao Jiu Xin dripping pill absorption in the buccal mucosa of healthy volunteers. This pill is a traditional Chinese medicine that is widely used as an emergency treatment for cardiovascular and cerebrovascular diseases. It is sublingually administered and can be absorbed in the buccal mucosa. In the present study, a method was developed to investigate the absorption characteristics in the buccal mucosa of healthy volunteers via a circulating device by gas chromatography-mass spectrometry and high-performance liquid chromatography. The five main efficacy components associated with cardiovascular and cerebrovascular diseases, which are borneol, isoborneol, ligustilide, n-butylphthalide and ferulic acid, were detected and rapidly absorbed. Among these components, four exhibited good absorption, thus confirming that the method developed is efficient for analysis of the absoption characteristics.

[Efficacy observation on acupuncture prescription of regulating yin-yang and five viscera for intractable insomnia].

OBJECTIVE: To explore a more optimal therapy for intractable insomnia. METHODS: Seven hundred cases of intractable insomnia that were in accordance with the criteria were randomly divided into an observation group (368 cases) and a control group (332 cases). The acupuncture prescription of regulating yin-yang and five viscera was applied in the observation group, where Dazhui (GV 14), Shenmai (BL 62), Guanyuan (CV 4), Zhaohai (KI 6), Geshu (BL 17), etc. were selected. The acupuncture prescription of tranquilizing mind was applied in the control group, where Baihui (GV 20), Sishencong (EX-HN 1), Anmian (Extra), Shenmen (HT 7), Sanyin jiao (SP 6) were selected. The treatment was given once a day, ten times of which made a session. After the treatment for 4 sessions, the clinical efficacy and Pittsburgh sleep quality index (PSQI) were compared between two groups. RESULTS: The total effective rate was 92.6% (338/365) in the observation group, which was superior to 73.1% (242/331) in the control group (P < 0.05). The PSQI score was obviously decreased in two groups after the treatment (both P < 0.05), in which the decreasing in the observation group was superior to that in the control group (P < 0.05). CONCLUSION: The acupuncture prescription of regulating yin-yang and five viscera has better effect for intractable insomnia, which could be considered as a more optimal therapy.

Effect of Bu-Zhong-Yi-Qi-Tang on deficiency of N-glycan/nitric oxide and islet damage induced by streptozotocin in diabetic rats.

AIM: To investigate the effect of Bu-Zhong-Yi-Qi-Tang (Decoction for Reinforcing Middle Jiao and Replenishing Qi) on deficiency of N-glycan/nitric oxide (NO) and islet damage induced by injecting two medium doses of streptozotocin (STZ). METHODS: Diabetes was induced by intraperitoneal injection of STZ at 55 mg/kg on day 1 and day 8. Islet damage was evaluated using a scoring system. Nitrite, nitrate, alpha-mannosidase and amylase activities were measured by colorimetry. N-glycan patterns of amylase were determined with lectin [ConA, pisum sativum agglutinin (PSA), peanut agglutinin (PNA), and lens culinaris agglutinin (LCA)] affinity precipitation method. RESULTS: Severe islet necrosis and mild islet atrophy were observed in diabetic rats. The number and size of islets, the activities of alpha-mannosidase, amylase and nitrite were decreased, while the binding of PNA and LCA to amylase was increased. All of which were improved after treatment with Bu-Zhong-Yi-Qi-Tang. Islet damage was significantly correlated with nitrite, nitrate, alpha-mannosidase, amylase and the binding of LCA, PNA, and PSA to amylase. CONCLUSION: STZ-induced islet damage is related to N-glycan deficiency in proteins by blocking alpha-mannosidase activity and no deficiency, accumulation of unfolded proteins, and endoplasmic reticulum stress and activation of cellular signals, all of which are improved after treatment with Bu-Zhong-Yi-Qi-Tang.

Expression of Chlamydophila psittaci MOMP heat-labile toxin B subunit fusion gene in transgenic rice.

A DNA fragment encoding the MOMP gene of Chlamydophila psittaci was fused to the heat-labile toxin B subunit gene (LTB-MOMP) and transferred into rice callus by Agrobacterium tumefaciens-mediated transformation. The LTB-MOMP fusion gene was detected in genomic DNA from transformed rice leaves by Southern blot and RT-PCR amplification. Synthesis and assembly of the LTB-MOMP fusion protein into pentamers was detected in transformed leaf extracts by immunoblot analysis. Binding of the pentamers to intestinal epithelial cell membrane glycolipid receptors was quantified by GM1-ganglioside enzyme-linked immunosorbent assay (GM1-ELISA). The ELISA results indicated that LTB-MOMP fusion protein made up 0.0033-0.0054% of the total soluble leaf protein. Meanwhile, this suggested that the fusion protein retained both its native antigenicity and the ability to form pentamers.
