Wutou decoction ameliorates experimental rheumatoid arthritis via regulating NF-kB and Nrf2: Integrating efficacy-oriented compatibility of traditional Chinese medicine.

BACKGROUND: Thousands of years of clinical application of Wutou decoction (WTD) support its reliable efficacy and safety in treating rheumatoid arthritis (RA). However, the underlying molecular mechanism remains unclear, and the synergistic involvement of assistant herbs in WTD in enhancing the sovereign herb in treating RA is unknown. PURPOSE: This study aimed to investigate the efficacy-oriented compatibility of five herbs in WTD and the underlying mechanisms. METHODS: The anti-arthritic effects of WTD and the compatibilities of the five herbs in WTD were studied in vivo with adjuvant-induced arthritis (AIA) rat model and in vitro with LPS-induced RAW264.7 macrophage. Network pharmacology analysis was conducted to identify the dominant pathways involved in the anti-arthritis mechanisms of WTD and how the five herbs work synergistically. The results were further verified by in vivo and in vitro experiments. RESULTS: Our data revealed that the five herbs in WTD exert synergistic anti-arthritic effects on RA. Moreover, Radix Aconite (AC) is the principal anti-inflammatory component in WTD according to the extent of therapeutic effects exerted on the AIA rats. In vivo and in vitro experiments demonstrated that WTD inhibited NF-κB phosphorylation and simultaneously increased the expression of Nrf2, which were the major pathways identified by the network pharmacology analysis. The major assistant component, Herba Ephedrae (EP), evidently inhibited NF-κB mediated inflammatory response. The other assistant component, Radix Astragali (AS), considerably enhanced the expression of Nrf2 when used alone or in combination with AC. These combinations improved the anti-arthritis effects on the AIA rats better than that of AC alone. Nevertheless, WTD always achieved the best effects than any combinations both in vivo and in vitro. CONCLUSION: The ministerial herbs EP and AS intensify the anti-arthritic effects of AC by regulating the NF-κB-mediated inflammatory pathway and the Nrf2-mediated anti-oxidation pathway which are the major pathways of WTD for alleviating the symptoms of RA.

Therapeutic Effect Evaluation of Neuromuscular Electrical Stimulation With or Without Strengthening Exercise on Spastic Cerebral Palsy.

The aims of this study were to investigate the effect of neuromuscular electrical stimulation (NMES) combined with strengthening exercise on movement in children with spastic cerebral palsy (CP). One hundred children with spastic CP were randomly divided into a treatment group (NMES and strengthening exercise, n = 50) and a control group (only NMES, n = 50). We compared the Comprehensive Spasticity Scale (CSS) score, Gross Motor Function Measure (GMFM) score, and walking speed before treatment and 6 weeks and 3 months after treatment between the 2 groups. There was no difference in CSS score between the treatment and control groups before the therapy (12.0 ± 3.4 vs 12.3 ± 3.6), which decreased much more in the treatment group after 6 weeks (7.6 ± 3.0 vs 9.5 ± 2.8) and 3 months (7.4 ± 2.4 vs 9.4 ± 2.6) with significant differences ( P < .05). No difference in GMFM score was observed between the treatment and control groups before the therapy (44.5 ± 13.2 vs 44.0 ± 12.6), which increased much more in the treatment group after 6 weeks (70.6 ± 15.2 vs 56.7 ± 14.3) and 3 months (71.0 ± 16.4 vs 58.0 ± 15.6) with significant differences ( P < .05). The walking speed improved over time, which was the same before the treatment (0.43 ± 0.13 m/s vs 0.45 ± 0.14 m/s), and was significantly greater in the treatment group than that in the control group (6 weeks: 0.69 ± 0.15 m/s vs 0.56 ± 0.12 m/s, P < .05; 3 months: 0.72 ± 0.17 m/s vs 0.57 ± 0.18 m/s, P < .05). NMES combined with strengthening exercise was more effective than NMES alone in the recovery of spastic CP.

Effect of acupuncture on inflammatory cytokines expression of spastic cerebral palsy rats.

OBJECTIVE: To To investigate the effect of acupuncture on the tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), C-reactive protein (CRP), nitric oxide synthase (NOS) content and muscular tension of spasticity cerebral palsy rat model. METHODS: The rats with spastic cerebral palsy were randomly divided into the control group, model group and acupuncture group. After successful modeling, the muscular tension and the content of TNF-α, IL-6, CRP, NOS were measured. RESULTS: The serum TNF-α, IL-6, CRP, NOS content were significantly decreased in the acupuncture group (P<0.05). The low and high shear viscosity of whole blood of the acupuncture group were significantly lower than the control group and the model group (P<0.05). The erythrocyte electrophoresis indexes in the acupuncture group were significantly lower than that in the model group and the control group (P<0.05). Acupuncture significantly reduced the muscular tension of spastic cerebral palsy rat and increased the active extent in the paralytic extremity (P<0.05), but it could not be restored to normal level. Compared with the control group, the difference had significant (P<0.05). CONCLUSIONS: Acupuncture treatment can inhibit the release of inflammatory cells after brain injury, then reduce immune injury, relieve muscle spasms and reduce muscular tension.

A 10-day sequential therapy for eradication of Helicobacter pylori infection in children / 中华儿科杂志

<p><b>OBJECTIVE</b>To evaluate the clinical effect of a 10-day sequential therapy which was made up of omeprazole, clarithromycin, amoxicillin-clavulanate and metronidazole for the eradication of Helicobacter pylori (Hp) infection in children.</p><p><b>METHOD</b>A total of 214 children with abdominal pain, who were confirmed to have Hp infection through endoscopy, biopsy, and Hp culture. The 214 cases were randomly divided into four groups. A 10-day sequential therapy group accepted omeprazole 0.8 - 1.0 mg/(kg·d) plus amoxicillin-clavulanate 50 mg/(kg·d) for five days and omeprazole 0.8 - 1.0 mg/(kg·d), clarithromycin 20 mg/(kg·d) and metronidazole 20 mg/(kg·d) for the remaining five days. The 7-day triple therapy group, 10-day triple therapy group and 14-day triple therapy group received omeprazole 0.8 - 1.0 mg/(kg·d), amoxicillin-clavulanate 50 mg/(kg·d) and clarithromycin 20 mg/(kg·d) for 7 days,10 days,14 days, respectively. All drugs were given twice daily. All these patients received (13)C urea breath test ((13)C-UBT) four weeks after the treatment.</p><p><b>RESULT</b>Finally, 199 patients were followed up, and the total rate of loss to follow-up was 7.0% (15/214). Hp eradication rate was 85.2% and 90.2% in the 10-day sequential therapy group on intention to treat (ITT) and per protocol (PP) analyses, 66.0% and 71.4% in the 7-day triple therapy group on ITT and PP analyses; 60.0% and 67.3% in 10-day triple therapy group on ITT and PP analyses, and 78.8% and 82.0% in patients who received the 10-day sequential regimen on ITT and PP analyses, respectively. By ITT analysis, there was significantly difference between the 10-day sequential therapy group and 7-day or 10-day triple therapy group (P < 0.05), while no significant difference was found between the 10-day sequential therapy group and 14-day triple therapy group (P > 0.05). The results of the ITT analysis and the PP analysis were the same. The four groups had neither significant difference in abdominal pain relief (P > 0.05) nor in incidence of adverse reactions (P > 0.05).</p><p><b>CONCLUSION</b>The 10-day sequential regimen was significantly more effective than both 7-day triple regimen and 10-day triple regimen, while had the same eradication rate compared with the 14-day sequential therapy. But 10-day triple regimen to eradicate Hp infection in children had the advantages such as short course of treatment and better compliance.</p>
