Research progress of Paris polyphylla in the treatment of digestive tract cancers.

Cancer has become one of the most important causes of human death. In particular, the 5 year survival rate of patients with digestive tract cancer is low. Although chemotherapy drugs have a certain efficacy, they are highly toxic and prone to chemotherapy resistance. With the advancement of antitumor research, many natural drugs have gradually entered basic clinical research. They have low toxicity, few adverse reactions, and play an important synergistic role in the combined targeted therapy of radiotherapy and chemotherapy. A large number of studies have shown that the active components of Paris polyphylla (PPA), a common natural medicinal plant, can play an antitumor role in a variety of digestive tract cancers. In this paper, the main components of PPA such as polyphyllin, C21 steroids, sterols, and flavonoids, amongst others, are introduced, and the mechanisms of action and research progress of PPA and its active components in the treatment of various digestive tract cancers are reviewed and summarized. The main components of PPA have been thoroughly explored to provide more detailed references and innovative ideas for the further development and utilization of similar natural antitumor drugs.

Anti-inflammatory effects of acupuncture in the treatment of chronic obstructive pulmonary disease.

Numerous randomised controlled trials have suggested the positive effects of acupuncture on chronic obstructive pulmonary disease (COPD). However, the underlying therapeutic mechanisms of acupuncture for COPD have not been clearly summarized yet. Inflammation is central to the development of COPD. In this review, we elucidate the effects and underlying mechanisms of acupuncture from an anti-inflammatory perspective based on animal studies. Cigarette smoke combined with lipopolysaccharide is often used to establish animal models of COPD. Electroacupuncture can be an effective intervention to improve inflammation in COPD, and Feishu (BL13) and Zusanli (ST36) can be used as basic acupoints in COPD animal models. Different acupuncture types can regulate different types of inflammatory cytokines; meanwhile, different acupuncture types and acupoint options have similar effects on modulating the level of inflammatory cytokines. In particular, acupuncture exerts anti-inflammatory effects by inhibiting the release of inflammatory cells, inflammasomes and inflammatory cytokines. The main underlying mechanism through which acupuncture improves inflammation in COPD is the modulation of relevant signalling pathways: nuclear factor-κB (NF-κB) (e.g., myeloid differentiation primary response 88/NF-κB, toll-like receptor-4/NF-κB, silent information regulator transcript-1/NF-κB), mitogen-activated protein kinase signalling pathways (extracellular signal-regulated kinase 1/2, p38 and c-Jun NH2-terminal kinase), cholinergic anti-inflammatory pathway, and dopamine D2 receptor pathway. The current synthesis will be beneficial for further research on the effect of acupuncture on COPD inflammation.

Regulatory Effects of Quercetin on Bone Homeostasis: Research Updates and Future Perspectives.

The imbalance of bone homeostasis has become a major public medical problem amid the background of an aging population, which is closely related to the occurrence of osteoporosis, osteoarthritis, and fractures. Presently, most drugs used in the clinical treatment of bone homeostasis imbalance are bisphosphonates, calcitonin, estrogen receptor modulators, and biological agents that inhibit bone resorption or parathyroid hormone analogs that promote bone formation. However, there are many adverse reactions. Therefore, it is necessary to explore potential drugs. Quercetin, as a flavonol compound with various biological activities, is widely distributed in plants. Studies have found that quercetin can regulate bone homeostasis through multiple pathways and targets. An in-depth exploration of the pharmacological mechanism of quercetin is of great significance for the development of new drugs. This review discusses the therapeutic mechanisms of quercetin on bone homeostasis, such as regulating the expression of long non-coding RNA, signaling pathways of bone metabolism, various types of programmed cell death, bone nutrients supply pathways, anti-oxidative stress, anti-inflammation, and activation of Sirtuins. We also summarize recent progress in improving quercetin bioavailability and propose some issues worth paying attention to, which may help guide future research efforts.

Can anterior vertebral body tethering provide superior range of motion outcomes compared to posterior spinal fusion in adolescent idiopathic scoliosis? A systematic review.

PURPOSE: Anterior vertebral body tethering (AVBT) was introduced as a fusionless alternative to treating adolescent idiopathic scoliosis (AIS) while preserving range of motion (ROM). This is the first systematic review to compare the ROM outcomes between AVBT and PSF in treating AIS. METHODS: We conducted a comprehensive search on PubMed, EMBASE, MEDLINE, and Cochrane Library. Inclusion criteria were patients with AIS treated with AVBT or PSF or both, and clearly defined ROM outcomes; exclusion criteria were scoliosis other than AIS, biomechanical or cadaveric studies, non-English publications, case reports, conference summaries, unpublished literature, commentaries, and reviews. Primary outcome was ROM. Secondary outcomes included Cobb angle correction, quality of life (QOL), complications, and muscle strength and endurance. RESULTS: Twelve studies were included in this review. We found moderate evidence to support that AVBT results in superior ROM outcomes than PSF while achieving comparable Cobb angle correction with low evidence. The comparison of QOL outcomes between AVBT and PSF remained inconclusive. In addition to the complications noted conventionally in PSF, AVBT could result in over-correction and distal adding-on. We also found very low evidence to support that AIS patients treated with AVBT have superior muscle strength and endurance when compared to those treated with PSF. CONCLUSIONS: AVBT provides better preservation of ROM and muscle strength postoperatively when compared with PSF, while achieving comparable curve correction. Future studies should explore the spinal growth trajectory to determine the window of opportunity for AVBT in AIS.

The association between serum folate and gestational diabetes mellitus: a large retrospective cohort study in Chinese population.

OBJECTIVE: To investigate the association between folate levels and the risk of gestational diabetes mellitus (GDM) risk during the whole pregnancy. DESIGN: In this retrospective cohort study of pregnant women, serum folate levels were measured before 24 gestational weeks (GW). GDM was diagnosed between 24th and 28th GW based on the criteria of the International Association of Diabetes and Pregnancy Study Groups. General linear models were performed to examine the association of serum folate with plasma glucose (i.e. linear regressions) and risk of GDM (i.e. log-binomial regressions) after controlling for confounders. Restricted cubic spline regression was conducted to test the dosage-response relationship between serum folate and the risk of GDM. SETTING: A sigle, urban hospital in Shanghai, China. PARTICIPANTS: A total of 42 478 women who received antenatal care from April 2013 to March 2017 were included. RESULTS: Consistent positive associations were observed between serum folate and plasma glucose levels (fasting, 1-h, 2-h). The adjusted relative risks (RR) and 95 % CI of GDM across serum folate quartiles were 1·00 (reference), 1·15 (95 % CI (1·04, 1·26)), 1·40 (95 % CI (1·27, 1·54)) and 1·54 (95 % CI (1·40, 1·69)), respectively (P-for-trend < 0·001). The positive association between serum folate and GDM remained when stratified by vitamin B12 (adequate v. deficient groups) and the GW of serum folate measurement (≤13 GW v. >13 GWs). CONCLUSIONS: The findings of this study may provide important evidence for the public health and clinical guidelines of pregnancy folate supplementation in terms of GDM prevention.

Using Herbal-Cake-Separated Moxibustion for the Treatment of Rats with Chronic Renal Failure.

In the process of moxibustion in clinical practice, subjects need to be in a stable mood and comfortable posture to avoid problems such as moxa ash falling, scalding skin, and poor curative effect. Such problems also exist in the rat moxibustion experiment. To simulate clinical practice, it is necessary to introduce an experimental instrument in animal experiments, that is, a moxibustion device with fixed rats and moxibustion treatment synchronization, which can make experimental rats receive moxibustion treatment quietly and comfortably under non-anesthesia. Our research group designed a rat moxibustion experimental platform. The device was framed by a wooden board with a supporting base plate, multiple fixed components, and partitioned components. The device can achieve the operation mode of moxibustion in rats without binding, avoiding anesthesia and scalding and simultaneously exposing multiple acupoints on the back. This operation can avoid physical and mental injury to rats and operators, which improves the research efficiency and further promotes the development and research of moxibustion animal experiments. The device has a simple structure, is easy to operate and popularize, is comprehensively and innovatively designed, reusable, and is suitable for rat experiments mainly based on moxibustion. This article mainly introduces the structure of the experimental platform device for rat moxibustion, the basic procedure of herbal-cake-separated-moxibustion in experimental rats using the device and describes the establishment of a rat model of chronic renal failure (CRF) and representative experimental results.

Cardioprotective effect of Chinese herbal medicine for anthracycline-induced cardiotoxicity in cancer patients: A meta-analysis of prospective studies.

BACKGROUND: To assess the benefits and harmful effects of Chinese herbal medicine (CHM) formulations in preventing anthracyclines (ANT)-induced cardiotoxicity. METHOD: The Cochrane Library, Pubmed and EMBASE databases were electronically searched for relevant randomized controlled trials (RCTs) published till December 2021 in English or Chinese-language, in addition to manual searches through the reference lists of the selected papers, and the Chinese Conference Papers Database. Data was extracted by 2 investigators independently. RESULT: Seventeen RCTs reporting 11 different CHMs were included in this meta-analysis. The use of CHM reduced the occurrence of clinical heart failure (RR 0.48, 95% CI 0.39 to 0.60, P < .01) compared to the control group. Data on subclinical heart failure in terms of LVEF values showed that CHM reduced the occurrence of subclinical heart failure (RR 0.47, 95% CI 0.35 to 0.62, P < .01) as well. CONCLUSION: CHM is an effective and safe cardioprotective intervention that can potentially prevent ANT-induced cardiotoxicity. However, due to the insufficient quality of the included trials, our results should be interpreted with cautious.

[Comparative study on short and long-term intervention impacts of six Chinese herbs with cold or heat property on lipid and energy metabolism in mice].

This study selected three typical Chinese herbs with cold property(Rhei Radix et Rhizoma, Scutellariae Radix, and Coptidis Rhizoma) and another three with heat property(Cinnamomi Cortex, Zingiberris Rhizoma, and Aconiti Lateralis Radix Praeparata) to observe their regulatory effects on metabolism in animal organism, especially on lipid and energy metabolism in mice after a short-(7 d) and long-term(35 d) intervention. The mRNA expression levels of lipid metabolism genes in epididymal adipose tissue and liver were determined by real-time PCR. The oxygen consumption, carbon dioxide production, and energy consumption were detected by metabolic system. After the short-term intervention, the Chinese herbs with heat property significantly reduced epididymal adipose tissue index and elevated the expression levels of acetyl-CoA carboxylase(ACC), lipoprotein lipase(LPL), and carnitine-palmityl transferase 1(CPT-1) in liver and epididymal adipose tissues. However, those with cold property promoted the expression of above-mentioned genes in epididymal adipose tissue. After the long-term intervention, cold and heat Chinese herbs had no significant effect on epididymal adipose tissue index of animals, while cold Chinese herbs could increase carbon dioxide production and energy consumption and reduce activity. These findings demonstrated that the short-term intervention effects of cold and heat Chinese herbs on animal metabolism were significantly stronger than the long-term intervention effects. Specifically, the short-term intervention with cold Chinese herbs enhanced the lipid metabolism in epididymal adipose tissue, while the heat Chinese herbs promoted lipid metabolism in epididymal adipose tissue and liver. The long-term intervention with cold and heat Chinese herbs resulted in no obvious change in lipid level, but long-term intervention with cold Chinese herbs accelerated energy consumption of the body. This study preliminarily observed the effects of cold and heat Chinese herbs on normal animal physiology from lipid and energy metabolism, which would provide reference for explaining the biological basis of Chinese herbs with cold or heat property based on biological response.

Efficacy of Wen-Luo-Tong on Peripheral Neuropathy Induced by Chemotherapy or Target Therapy: A Randomized, Double-Blinded, Placebo-Controlled Trial.

OBJECTIVE: To evaluate the efficacy of Wen-Luo-Tong Granules (WLT) local administration in the treatment of patients with peripheral neuropathy (PN) induced by chemotherapy or target therapy. METHODS: This study is a randomized, double-blinded, and placebo-controlled trial. Seventy-eight patients with PN induced by chemotherapy or target therapy were enrolled from China-Japan Friendship Hospital between July 2019 and January 2020. They were randomly assigned to WLT (39 cases) and control groups (39 cases) using a block randomization method. The WLT group received WLT (hand and foot bath) plus oral Mecobalamin for 1 week, while the control group received placebo plus oral Mecobalamin. The primary endpoint was PN grade evaluated by the National Cancer Institute-Common Toxicity Criteria for Adverse Events (NCI-CTCAE). The secondary endpoints included quantitative touch-detection threshold, neuropathy symptoms, Quality of Life Questionnaire-Chemotherapy Induced Peripheral Neuropathy (QLQ-CIPN20), and Quality of Life Questionnaire-Core30 (QLQ-C30). RESULTS: After treatment, the PN grade in the WLT group was significantly lower than that in the control group (1.00 ± 0.29 vs. 1.75 ± 0.68, P<0.01). The total effective rate in the WLT group was significantly higher than that in the control group (82.05% vs. 51.28%, P<0.01). Compared with the control group, the touch-detection thresholds at fingertips, neuropathy symptom score, QLQ-CIPN 20 (sensory scale, motor scale, autonomic scale, and sum score), and QLQ-C30 (physical functioning, role functioning, emotional functioning, and global health) in the WLT group significantly improved after treatment (P<0.01 or P<0.05). CONCLUSION: WLT local administration was significantly effective in the treatment of patients with PN induced by chemotherapy or target therapy. (Trial registration No. ChiCTR1900023862).

seco-Prezizanne Sesquiterpenes and Prenylated C6-C3 Compounds from the Fruits of Illicium lanceolatum A. C. Smith.

Two new seco-prezizaane-type sesquiterpenes, 2ß-hydroxy-6-deoxyneoanisatin (1) and 3,4-anhydro-2-oxo-1α-hydroxy-6-deoxyneoanisatin (2), and two new prenylated C6 -C3 compounds, illilanceofunones A (3) and B (4), were obtained from the fruits of Illicium lanceolatum, along with four known prenylated C6 -C3 compounds (5-8). Their structures were proposed through HR-ESI-MS, 1 H, 13 C, and 2D NMR data interpretation. Moreover, the absolute configuration of 1 and 2 were further assigned by single-crystal X-ray diffraction analysis and electronic circular dichroism (ECD) calculations, respectively. Illihenryipyranol A (6) exhibited neuroprotective activity against MPP+ -induced PC12 cell damage in a dose-dependent manner.

Combination of Activating Blood Circulation and Detoxifying Chinese Medicines Played an Anti-Inflammatory Role in Unstable Angina Patients after Percutaneous Coronary Intervention: A Multicenter, Open-Labeled, Randomized Controlled Trial.

OBJECTIVE: To investigate the combined anti-inflammatory effect of activating blood circulation and detoxifying Chinese medicines in unstable angina (UA) patients. METHODS: This study was an open-labeled, randomized controlled trial conducted in 5 centers in Beijing. A total of 154 patients were randomized into two groups at a 1:1 ratio by random numbers. Based on the conventional treatment, patients in the activating blood circulation (ABC) group were treated with Guanxin Danshen Droping Pill (, 0.4 g, thrice daily), and patients in the activating blood circulation and detoxifying (ABCD) group were treated with Guanxin Danshen Droping Pill (0.4 g, thrice daily) and Andrographis tablet (0.2 g, thrice daily) for 4 weeks. The primary outcome was the serum level of high sensitive C reaction protein (hs-CRP), and the secondary outcome index included the serum levels of tumor necrosis factor α (TNF-α), interleukin 6 (IL-6), soluble CD40 ligand (sCD40L), thrombomodulin (TM), the score of angina pectoris, the score of blood stasis syndrome, and the score of Chinese medicine symptoms, observed at week 0 and week 4. RESULTS: A total of 144 patients completed the trial (ABC group, n=70; ABCD group, n=74). There were no significant differences in the clinical baseline characteristics between the two groups. When compared with the ABC group, ABCD group showed better performance in reducing the level of inflammatory factors, especially hs-CRP (P<0.05), IL-6 (P<0.01) and TNF-α (P<0.01). In term of clinical symptoms, ABCD group played a better role in improving the scores of angina pectoris and blood stasis syndrome than ABC group (all P<0.05). CONCLUSIONS: The combination of Guanxin Danshen Dropping Pill and Andrographis tablet exert significant anti-inflammatory effect on UA patients, which is superior to single Guanxin Danshen Dropping Pill.

[on oligozoospermia and asthenospermia].

OBJECTIVE: To observe the clinical effect of Yihechun Capsules (YHC) on oligozoospermia and asthenospermia. METHODS: A total of 181 male patients with infertility were randomly divided into a YHC+Levocarnitine (LC) group (n = 93, including 42 cases of oligozoospermia, 20 cases of asthenospermia and 31 cases of oligoasthenospermia) and an LC control group (n = 88, including 39 cases of oligozoospermia, 22 cases of asthenospermia and 27 cases of oligoasthenospermia), the former treated with YHC (ï¼»0.3 g per capsuleï¼½, once 4 capsules, bid, 30 minutes after meal) combined with LC oral liquid (2－3 g/d, tid, at mealtime) and the latter with LC oral liquid only (2－3 g/d, tid, at mealtime). After 3 months of treatment, comparisons were made between the two groups of patients in sperm concentration, the percentages of grade a and grade a+b sperm, and the rate of pregnancy. RESULTS: Of the 181 patients, 5 in the YHC+LC group and 2 in the LC control group failed to complete the course of treatment. There were no statistically significant differences between the two groups of patients in the baseline sperm concentration and the percentages of grade a and grade a+b sperm (P > 0.05), wich were all markedly increased in both the YHC+LC and the LC control groups (P < 0.05) after 3 months of treatment. And the patients of the YHC+LC group, compared with the controls, showed even more significant increases, as the oligozoospermia patients in sperm concentration (ï¼»21.07 ± 6.98ï¼½ vs ï¼»16.56 ± 1.82ï¼½ ×106/ml, P < 0.05) and the percentages of grade a sperm (ï¼»27.53 ± 3.34ï¼½% vs ï¼»26.88 ± 1.35ï¼½%, P < 0.05) and grade a+b sperm (ï¼»53.32 ± 3.16ï¼½% vs ï¼»52.63 ± 2.48ï¼½%, P < 0.05), the asthenospermia patients in sperm concentration (ï¼»26.36 ± 3.37ï¼½ vs ï¼»24.42 ± 2.21ï¼½ ×106/ml, P < 0.05) and the percentages of grade a sperm (ï¼»25.28 ± 4.64ï¼½% vs ï¼»21.32 ± 3.28ï¼½%, P < 0.05) and grade a+b sperm (ï¼»49.19 ± 2.87ï¼½% vs ï¼»45.64 ± 1.78ï¼½%, P < 0.05), and the oligoasthenospermia patients in sperm concentration (ï¼»19.38 ± 3.39ï¼½ vs ï¼»18.75 ± 1.35ï¼½ ×106/ml, P < 0.05) and the percentages of grade a sperm (ï¼»22.65 ± 4.81ï¼½% vs ï¼»21.31 ± 2.42ï¼½%, P < 0.05) and grade a+b sperm (ï¼»48.74 ± 5.61ï¼½% vs ï¼»44.36 ± 1.32ï¼½%, P < 0.05). The pregnancy rate was dramatically higher in the YHC+LC than in the LC control group (36.4% ï¼»32/88ï¼½ vs 15.1% ï¼»13/86ï¼½, P < 0.01). CONCLUSIONS: Yihechun Capsules combined with Levocarnitine oral liquid is evidently effective for the treatment of oligozoospermia and asthenospermia.

The effectiveness of Baduanjin exercise for hypertension: a systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: Hypertension, a major risk factor of cardiovascular mortality, is a critical issue for public health. Although Baduanjin (Eight Brocades, EB), a traditional Chinese exercise, might influence blood pressure, glucose, and lipid status, the magnitude of true effects and subgroup differences remains unclear. Therefore, we performed a systematic review of relevant randomized controlled trials (RCTs) to evaluate the effect of EB on patient-important outcomes. METHODS: We systematically searched PubMed, the Cochrane Library, Web of Science, and Chinese databases since inception until March 30, 2020. Meta-analysis was carried out using "meta" package in R 3.4.3 software. A prespecified subgroup analysis was done according to the type of comparisons between groups, and the credibility of significant subgroup effects (P < 0.05) were accessed using a five-criteria list. A GRADE evidence profile was constructed to illustrate the certainty of evidence. RESULTS: Our meta-analysis, including 14 eligible trials with 1058 patients, showed that compared with routine treatment or health education as control groups, the mean difference (MD) in systolic blood pressure (SBP) of the EB groups was - 8.52 mmHg (95%CI:[- 10.65, - 6.40], P < 0.01) and diastolic blood pressure (DBP) was - 4.65 mmHg (95%CI: [- 6.55, - 2.74], P < 0.01). For blood pressure, the evidence was, however, of low certainty because of risk of bias and inconsistency, and for the outcomes of most interest to patients (cardiovascular morbidity and mortality directly), of very low certainty (measurement of surrogate only). Subgroup analysis showed there was no significant interaction effect between different type of comparisons (SBP P = 0.15; DBP P = 0.37), so it could be easily attributed to chance. CONCLUSION: Regularly EB exercising may be helpful to control blood pressure, but the evidence is only low certainty for blood pressure and very low certainty for cardiovascular morbidity and mortality. Rigorously designed RCTs that carry out longer follow-up and address patient-important outcomes remain warranted. TRIAL REGISTRATION: PROSPERO Registration number: CRD42018095854 .

Echinacoside prevents hypoxic pulmonary hypertension by regulating the pulmonary artery function.

Hypoxic pulmonary hypertension (HPH) is a progressive and irreversible disease that reduces survival. Echinacoside is a phenylethanoid glycoside from Tibetan herbs known for its vasorelaxant effect and for inhibiting the proliferation of rat pulmonary arterial smooth muscle cells. This study aimed to investigate the effect of echinacoside on HPH. Sprague Dawley rats were housed in a hypobaric hypoxia chamber (4500 m) for 28 days to obtain the HPH model. Echinacoside (3.75, 7.5, 15, 30 and 40 mg/kg) was administered by intraperitoneal injection from the 1st to the 28th day. The mean pulmonary artery pressure (mPAP), right ventricular hypertrophy index, hemoglobin, hematocrit, red blood cell concentration and morphological change of pulmonary arteries were evaluated. Vascular perfusion assay was used to assess the pulmonary artery function. Echinacoside reduced mPAP, hemoglobin, hematocrit, right ventricular hypertrophy index and mean wall thickness% of pulmonary arteries in HPH rats. It significantly increased maximum vasoconstriction percentage of pulmonary arteries induced by noradrenaline in a dose-dependent manner. In addition, it improved the responsiveness of pulmonary arteries to acetylcholine and sodium nitroprusside. Therefore, Echinacoside might be an effective treatment against HPH, since it regulated pulmonary artery endothelium and smooth muscle layer function and improved the remodeling of pulmonary artery.

Radial Pulse Wave Signals Combined with Ba-PWV for the Risk Prediction of Hypertension and the Monitoring of Its Accompanying Metabolic Risk Factors.

Our aim was to study whether radial pulse wave signals can improve the risk prediction of incident hypertension and are associated with its concomitant metabolic risk factors beyond the traditional cardiovascular risk factor Ba-PWV. By enrolling 523 Chinese subjects in this study, linear and stepwise regression analysis was performed to assess the association of radial artery pulse wave signals and Ba-PWV with blood pressure and its related metabolic risk factors such as fasting plasma glucose (FPG), total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and uric acid (UA). The area under the receiver-operating characteristic curve (AUC), net reclassification improvement (NRI), and integrated discrimination improvement (IDI) were calculated by risk assessment plot to compare the discriminative ability among models with and without radial artery pulse wave signals. After adjusting related confounding factors, radial artery pulse wave variable h 3/h 1 was selected as the sensitive influential factor for blood pressure. Moreover, a new model with h 3/h 1 had a higher AUC than the reference model without it (0.86 vs 0.84; P=0.030). And the NRI and IDI for the new model was 50.0% (P=0.017) and 3.16% (P=0.044), respectively. In addition to Ba-PWV, we found that the decrease of t 4, t 5, and h 5 might be associated with higher FPG, TC, LDL-C, and UA and lower HDL-C. This research might provide a valuable additional tool for remote wearable monitoring of radial artery pulse wave signals in hypertension risk evaluation and management.

Suppression of peripheral NGF attenuates neuropathic pain induced by chronic constriction injury through the TAK1-MAPK/NF-κB signaling pathways.

BACKGROUND: Anti-nerve growth factor (NGF) monoclonal antibodies (anti-NGF mAbs) have been reported to significantly attenuate pain, but the mechanism involved has not been fully elucidated, and the serious adverse events associated with mAbs seriously limit their clinical use. This study further investigated the mechanism by which peripheral NGF is involved in neuropathic pain and found safe, natural compounds that target NGF to attenuate neuropathic pain. METHODS: Nociception was assessed by the Von Frey hair and Hargreaves' methods. Western-blotting, qPCR and immunofluorescence were used to detect the cell signaling pathway. RAW264.7 macrophages and RSC96 Schwann cells were cultured for in vitro evaluation. RESULTS: Intraplantar administration of anti-NGF mAbs suppressed the expression of phosphorylated transforming growth factor-ß-activated kinase 1 (TAK1) in the dorsal root ganglion (DRG) and sciatic nerve. Intraplantar administration of a TAK1 inhibitor attenuated CCI-induced neuropathic pain and suppressed the expression of phosphorylated mitogen-activated protein kinases (MAPKs) in the DRG and sciatic nerve. Perisciatic nerve administration of levo-corydalmine (l-CDL) on the operated side obviously attenuated CCI-induced neuropathic pain and suppressed the expression of mNGF and proNGF. In addition, l-CDL-induced antinociception was reversed by intraplantar administration of NGF. Further results indicated that l-CDL-induced suppression of phosphorylated TAK1, MAPKs, and p65 and expression of the proinflammatory cytokines TNF-α and IL-1ß in the DRG and sciatic nerve were all abolished by NGF. In addition, in vitro experiments indicated that l-CDL suppressed the secretion of NGF and proNGF in RAW264.7 macrophages and RSC96 Schwann cells, which was abolished by AP-1 and CREB agonists, respectively. CONCLUSIONS: This study showed NGF inhibition suppressed TAK1 in the periphery to attenuate CCI-induced neuropathic pain through inhibition of downstream MAPK and p65 signaling. The natural compound l-CDL inhibited NGF secretion by macrophages and Schwann cells and downstream TAK1-MAPK/NF-κB signaling in the periphery to attenuate CCI-induced neuropathic pain. Video abstract Proposed mechanisms underlying the effect of l-CDL in periphery of CCI rats. In CCI rats, macropahages and Schwann cells could secret NGF to act on the receptors in the periphery to activate TAK1-MAPK/NF-κB axis and promote the release of proinflammatory cytokines, including TNF-α and IL-1ß to promote neuropathic pain. l-CDL decreased the secretion of NGF through inhibiting AP-1 and CREB respectively in RAW264.7 and RSC96 Schwann cells to attenuate CCI-induced neuropathic pain by inhibiting the TAK1-p38 MAPK/NF-κB signaling pathway.

Magnesium and vitamin C supplementation attenuates steroid-associated osteonecrosis in a rat model.

Magnesium (Mg)-based biometal attracts clinical applications due to its biodegradability and beneficial biological effects on tissue regeneration, especially in orthopaedics, yet the underlying anabolic mechanisms in relevant clinical disorders are lacking. The present study investigated the effect of magnesium (Mg) and vitamin C (VC) supplementation for preventing steroid-associated osteonecrosis (SAON) in a rat experimental model. In SAON rats, 50 mg/kg Mg, or 100 mg/kg VC, or combination, or water control was orally supplemented daily for 2 or 6 weeks respectively. Osteonecrosis was evaluated by histology. Serum Mg, VC, and bone turnover markers were measured. Microfil-perfused samples prepared for angiography and trabecular architecture were evaluated by micro-CT. Primary bone marrow cells were isolated from each group to evaluate their potentials in osteoblastogenesis and osteoclastogenesis. The mechanisms were tested in vitro. Histological evaluation showed SAON lesions in steroid treated groups. Mg and VC supplementation synergistically reduced the apoptosis of osteocytes and osteoclast number, and increased osteoblast surface. VC supplementation significantly increased the bone formation marker PINP, and the combination significantly decreased the bone resorption marker CTX. TNFα expression and oxidative injury were decreased in bone marrow in Mg/VC/combination group. Mg significantly increased the blood perfusion in proximal tibia and decreased the leakage particles in distal tibia 2 weeks after SAON induction. VC significantly elevated the osteoblast differentiation potential of marrow cells and improved the trabecular architecture. The combination supplementation significantly inhibited osteoclast differentiation potential of marrow cells. In vitro study showed promoting osteoblast differentiation effect of VC, and anti-inflammation and promoting angiogenesis effect of Mg with underlying mechanisms. Mg and VC supplementation could synergistically alleviate SAON in rats, indicating great translational potentials of metallic minerals for preventing SAON.
