[PMID: 25206561 PMCID: PMC4145935 DOI: 10.3969/j.issn.1673-5374.2013.27.002] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2013] [Accepted: 07/01/2013] [Indexed: 11/18/2022] Open
Abstract
In this study, we aimed to explore the role of ursolic acid in the neural regeneration of the injured sciatic nerve. BALB/c mice were used to establish models of sciatic nerve injury through unilateral sciatic nerve complete transection and microscopic anastomosis at 0.5 cm below the ischial tube-rosity. The successfully generated model mice were treated with 10, 5, or 2.5 mg/kg ursolic acid via intraperitoneal injection. Enzyme-linked immunosorbent assay results showed that serum S100 protein expression level gradually increased at 1-4 weeks after sciatic nerve injury, and significantly decreased at 8 weeks. As such, ursolic acid has the capacity to significantly increase S100 protein expression levels. Real-time quantitative PCR showed that S100 mRNA expression in the L4-6 segments on the injury side was increased after ursolic acid treatment. In addition, the muscular mass index in the soleus muscle was also increased in mice treated with ursolic acid. Toluidine blue staining revealed that the quantity and average diameter of myelinated nerve fibers in the injured sciatic nerve were significantly increased after treatment with ursolic acid. 10 and 5 mg/kg of ursolic acid produced stronger effects than 2.5 mg/kg of ursolic acid. Our findings indicate that ursolic acid can dose-dependently increase S100 expression and promote neural regeneration in BALB/c mice following sciatic nerve injury.

Zhang WL, Choi RCY, Zhan JYX, Chen JP, Luk WKW, Yao P, Dong TTX, Tsim KWK. Can Hedysari Radix replace Astragali Radix in Danggui Buxue Tang, a Chinese herbal decoction for woman aliment? PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2013; 20:1076-1081. [PMID: 23746954 DOI: 10.1016/j.phymed.2013.04.016] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/25/2013] [Revised: 04/08/2013] [Accepted: 04/21/2013] [Indexed: 06/02/2023]
Abstract
Astragali Radix (AR) has been used for over 2000 years in China for the enrichment of "Qi". Hedysari Radix (HR), a herb having similar chemical composition with AR, has been commonly used as a substitute of AR in herbal decoction. In order to evaluate the possible replacement of HR for AR in Chinese herbal decoction, systematic comparison of AR and HR was done by chemical and biological assessments. The water extract of AR contained higher levels of calycosin, calycosin-glucoside, ononin, astragaloside III and astragaloside IV, while higher amount of formononetin was found in the HR extract. The estrogenic, erythropoetic and osteogenic effects were compared between the water extracts of AR and HR, and in all cases AR extract showed higher biological activities. Danggui Buxue Tang (DBT) is a very common herbal decoction for woman aliment, and which contains AR and Angelica Sinensis Radix. Here, we generated two forms of DBT having either AR or HR as the major herbs. Chemically, AR-contained DBT showed higher amounts of various active chemicals, except formononetin that was higher in HR-contained DBT. In parallel, the estrogenic, osteogenic and erythropoetic effects of DBT containing AR showed better activities than that of DBT having HR. Thus, AR and HR showed distinct differences in terms of chemical and biological properties. In order to achieve the best therapeutical effect, as well as to guarantee the safety, AR is recommended here to be used for making DBT.

Abstract
The cerebral ischemia-reperfusion model was established using the suture occlusion method, and rats were intraperitoneally given 8 mL/kg Danhong injection once a day prior to model establishment. Rat brain tissues were harvested at 6, 24, 48, 72 hours after reperfusion. Immunohistochemical staining showed that transforming growth factor-β1 expression increased, while Golgi matrix protein GM130 expression decreased after cerebral ischemia-reperfusion. Danhong injection was shown to significantly up-regulate the expression of transforming growth factor-β1 and GM130, and expression levels peaked at 7 days after reperfusion. At 7 days after cerebral ischemia-reperfusion, Golgi morphology was damaged in untreated rats, while Golgi morphology breakage was not observed after intervention with Danhong injection. These experimental findings indicate that Danhong injection can up-regulate the expression of transforming growth factor-β1 and GM130, and maintain Golgi stability, thus playing a neuroprotective role in rats after cerebral ischemia-reperfusion.

Abstract
Corticotropin-releasing factor (CRF) and corticotropin-releasing factor receptor (CRFR) play important roles in stress response, including anxiety and depression syndrome. The CRF expression also relates to chronic stress-related hair loss. This study utilizes the world's largest traditional Chinese medicine (TCM) database and molecular dynamics (MD) simulations to investigate novel CRFR inhibitors for treatment of alopecia. The docking and screening from TCM database results indicate the vitamin B2, 3 beta-isodihydrocadambine, and caribine display higher binding affinity than maltose in maltose binding protein (MBP). However, the results of MD simulation shows the caribine-facilitated CRFR approach closer to MBP, the 3D structure conformation of MBP and CRFR complex forms compact structure. Interestingly, the distance between the two proteins is reducing significantly after caribine dock into MBP binding site. Beside, from Ligand channel analysis, the paths of caribine demonstrate that residence time is increased in binding pocket. Hence, our finding suggests that caribine might be a potential lead compound to stimulate MBP and CRFR interaction, and help for baldless therapy in further study.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Xanthii Fructus (XF) is commonly called "Cang-Erzi" in traditional Chinese medicine (TCM) and widely used for the treatment of sinusitis, headache, rheumatism, and skin itching. However, the clinical utilization of XF is relatively restricted owing to its toxicity. AIM OF THE STUDY To discover the characteristic potential biomarkers in rats treated with XF by urinary metabonomics. MATERIALS AND METHODS Ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-QTOF-MS) was applied in the study. The total ion chromatograms obtained from control and different dosage groups were distinguishable by a multivariate statistical analysis method. RESULTS The greatest difference in metabolic profile was observed between high dosage group and control group, and the metabolic characters in rats treated with XF were perturbed in a dose-dependent manner. The metabolic changes in response for XF treatment were observed in urinary samples, which were revealed by orthogonal projection to latent structures discriminate analysis (OPLS-DA), and 10 metabolites could be served as the potential toxicity biomarkers. In addition, the mechanism associated with the damages of lipid per-oxidation and the metabolic disturbances of fatty acid oxidation were investigated. CONCLUSIONS These results indicate that metabonomics analysis in urinary samples may be useful for predicting the toxicity induced by XF.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The aerial parts of Senecio scandens Buch.-Ham. (family Asteraceae) have a long history in traditional Chinese medicine as a treatment for various ailments, such as bacterial diarrhea, enteritis, conjunctivitis, and respiratory tract infections. MATERIALS AND METHODS A bibliographic investigation of Senecio scandens was accomplished by analyzing secondary sources, including the Chinese Medicinal plantal Classics, the Internet (Google Scholar and Baidu Scholar), and scientific databases accepted worldwide (Pubmed, Scopus, Web of Science, SciFinder, and CNKI). These sources were scrutinized for available information about the uses of Senecio scandens in traditional Chinese medicine, phytochemistry, pharmacology, and toxicology. RESULTS Senecio scandens is a medicinal plant with a climbing woody stem. Phytochemical studies have shown the presence of numerous valuable compounds, such as flavonoids, alkaloids, phenolic acids, terpenes, volatile oils, carotenoids, and trace elements. Among them, PAs are the characteristic constituents, adonifoline is one of the index ingredients of Senecio scandens. Studies in modern pharmacology have demonstrated that extracts and compounds isolated from Senecio scandens show a wide spectrum of pharmacological activities, including anti-inflammatory, antimicrobial, anti-leptospirosis, hepatoprotective, anti-infusorial, antioxidant, antiviral, antitumoral, analgesic, mutagenic, and toxicological activities. CONCLUSIONS Phytochemical and pharmacological studies have demonstrated that the extracts of the plant possess various pharmacological activities that can be attributed to the presence of various flavonoids, phenolic acids, and alkaloids. Newer technologies for qualitative and quantitative methods of PAs need to be developed to obtain better accuracy and sensitivity. Due to the toxicity of PAs present in this medicinal plant, the regulations on PAs of Senecio scandens were varied among different countries and regions. In China, the PAs toxicity of Senecio scandens ranking criteria is not well defined in the Chinese Pharmacopoeia 2010, and there is no strict uniform requirement on the PAs in western countries. We propose that the use of Senecio scandens should be reevaluated based on a set of criteria, which includes risk-benefit analysis and severity of the toxic effects, clinical and preclinical data to ensure safe use while continuing to satisfy the need for access to the medicinal plant.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Polyporus umbellatus (Pers.) Fries (Polyporaceae, Zhuling ) has been commonly used in medicine for a wide range of ailments related to the edema, scanty urine, vaginal discharge, urinary dysfunction, as well as jaundice and diarrhea. AIM OF THE REVIEW The present paper reviewed the traditional uses, propagation, phytochemistry, pharmacology, pharmacokinetics and quality control of Polyporus umbellatus. MATERIALS AND METHODS All the available information on Polyporus umbellatus was collected via a library and electronic search (using Web of Science, Pubmed, ScienceDirect, Splinker, Google Scholar, etc.). RESULTS Phytochemical studies showed the presence of many valuable secondary metabolites such as steroids, polysaccharides, anthraquinones and nucleosides. Crude extracts and isolated compounds showed a wide spectrum of pharmacological activities including diuretic, nephroprotective, anti-cancer, immuno-enhancing, hepatoprotective, anti-inflammatory and antioxidative activities. The pharmacokinetic studies demonstrated that the ergosterol and ergone had a high distribution and absorption in the plasma and the two main components of Polyporus umbellatus were mainly excreted by faeces. The determination of multiple chemical components was successfully applied to the quality control of Polyporus umbellatus. CONCLUSIONS Modern phytochemical, pharmacological and metabonomic investigations showed that the crude extracts and isolated compounds from Polyporus umbellatus possess many kinds of biological functions, especially in the diuretic activities and the treatment of kidney diseases as well as anti-cancer, immuno-enhancing and hepatoprotective activities. The pathways of the distribution, absorption, metabolism and excretion of main steroidal compounds were clarified by pharmacokinetic studies. Most of the pharmacological studies were conducted using crude and poorly characterized extracts of Polyporus umbellatus in animals especially in case of diuretic activities and the treatment of kidney diseases. Thus, more bioactive components especially diuretic compounds should be identified using bioactivity-guided isolation strategies and the possible mechanism of action as well as potential synergistic or antagonistic effects of multi-component mixtures derived from Polyporus umbellatus need to be evaluated integrating pharmacological, pharmacokinetic, bioavailability-centered and physiological approaches. In addition, more experiments including in vitro, in vivo and clinical studies should be encouraged to identify any side effects or toxicity. These achievements will further expand the existing therapeutic potential of Polyporus umbellatus and provide a beneficial support to its future further clinical use in modern medicine.

Abstract
The Chinese herb Shuyusan, whose main constituent is jasminoidin, has been shown to protect SH-SY5Y cells against corticosterone-induced damage. SH-SY5Y cells injured by 400 μmol/L corticosterone were treated with 5 and 30 μg/mL Shuyusan-containing serum. Results revealed that Shuyusan-containing serum elevated the survival rate of SH-SY5Y cells, reduced Bax expression, increased Bcl-2 expression, markedly elevated brain-derived neurotrophic factor mRNA expression, and blocked cell apoptosis. Moreover, the effect of high-dose (30 μg/mL) Shuyusan-containing serum was more remarkable. Therefore, Shuyusan-containing serum appears to protect SH-SY5Y cells against corticosterone-induced impairment by adjusting the expression of apoptosis-associated proteins and brain-derived neurotrophic factor. Moreover, high-dose Shuyusan-containing serum has a protective effect on high-dose corticosterone-induced impairment.

Abstract
This study aims to examine resources and utilization of traditional Chinese medicine (TCM) and factors influencing TCM utilization in urban community health centers (CHCs) in Hubei Province of China. A cross-sectional survey including 234 government-owned CHCs was conducted in 2009. One-way analysis of variance analysis and a Poisson regression model were used to examine distribution of TCM resources and factors influencing TCM utilization. This study found unequal distribution of TCM resources among districts. TCM outpatient visits were positively associated with higher economic development districts, lower initial capital investment of the CHCs, health services covered by health insurance, higher qualification of TCM physicians, provision of TCM health records and rehabilitation, and greater availability of herbal medicine. To achieve equal access to TCM services, policy makers should consider the socioeconomic differences and income groups, provide training for TCM physicians, build pathway to recruit senior TCM physicians, and cover more TCM therapies by health insurance.

Abstract
Jiao-Tai-Wan (JTW), a classical Chinese prescription, has been clinically employed to treat diabetes mellitus in recent years. To investigate the comparative evaluations on anti-diabetic effects and pharmacokinetics of the active ingredient berberine in mice treated with JTW in various combinations of its constituent herbs. In our study, the anti-diabetic study was carried out in diabetic mice induced by intraperitoneal injection of streptozotocin. The diabetic mice were randomly assigned to three therapy groups and orally administered with different prescription proportions of Rhizoma Coptidis and Cinnamomum cassia respectively. The level of plasma glucose, lipid profile and parameters related to oxidative stress were determined. The concentrations of berberine in non-diabetic mice plasma were determined using HPLC, and main pharmacokinetic parameters were investigated. The results indicated that the compatibility effects of ingredients present in Cinnamomum cassia could affect the anti-diabetic ability and pharmacokinetics of berberine in JTW.

Abstract
The Xingnao Jieyu capsule has been shown to effectively relieve neurologic impairments and lessen depression. It remains poorly understood whether this capsule can be used to treat post-stroke depression. Thus, in the present study, we established a rat model of post-stroke depression using left middle cerebral artery occlusions in combination of chronic unpredictable stress and solitary housing during development. Experimental rats received intragastric perfusion with 0.82, 0.41, and 0.20 g/kg Xingnao Jieyu capsules separately dissolved in 2 mL distilled water. Fluoxetine served as a positive control. The treatment was conducted over 28 days. Sugar water consumption test, open-field test, real-time fluorescent quantitative PCR and immunohistochemical staining results demonstrated that intragastric perfusion with various doses of Xingnao Jieyu capsules increased sugar water consumption, voluntary behaviors and synaptotagmin mRNA and protein expression in rats with post-stroke depression. These therapeutic effects were similar to those of fluoxetine. These results indicate that Xingnao Jieyu capsules upregulate synaptotagmin expression in hippocampi of rats with post-stroke depression, and exert antidepressant effects.

Abstract
This study used a novel combination of in vivo and in vitro experiments to show that Braintone had neuroprotective effects and clarified the molecular mechanisms underlying its efficacy. The Chinese herbal extract Braintone is composed of Radix Rhodiolase Essence, Radix Notoginseng Essence, Folium Ginkgo Essence and Rhizoma Chuanxiong. In vivo experiments showed that cerebral infarction volume was reduced, hemispheric water content decreased, and neurological deficits were alleviated in a rat model of permanent middle cerebral artery occlusion after administration of 87.5, 175 or 350 mg/kg Braintone for 7 consecutive days. Western blot analysis showed that Braintone enhanced the expression of hypoxia-inducible factor 1α, heme oxygenase-1 and vascular endothelial growth factor in the ischemic cortex of these rats. The 350 mg/kg dose of Braintone produced the most dramatic effects. For the in vitro experiments, prior to oxygen-glucose deprivation, rats were intragastrically injected with 440, 880 or 1 760 mg/kg Braintone to prepare a Braintone-containing serum, which was used to pre-treat human umbilical vein endothelial cells for 24 hours. Human umbilical vein endothelial cell injury was alleviated with this pre-treatment. Western blot and real-time PCR analysis showed that the Braintone-containing serum increased the levels of hypoxia-inducible factor 1α mRNA and protein, heme oxygenase-1 protein and vascular endothelial growth factor mRNA in oxygen-glucose deprived human umbilical vein endothelial cells. The 1 760 mg/kg dose produced the greatest increases in expression. Collectively, these experimental findings suggest that Braintone has neuroprotective effects on ischemia-induced brain damage via the up-regulation of hypoxia-inducible factor 1α, heme oxygenase-1 and vascular endothelial growth factor expression in vascular endothelial cells.

Abstract
BACKGROUND To compare the safety and efficacy of the traditional Chinese medicine Shenqi particle and standard therapy with prednisone and cyclophosphamide (control) in adult patients with idiopathic membranous nephropathy (IMN). STUDY DESIGN Open-label, multicenter, parallel, randomized, controlled clinical trial. SETTING & PARTICIPANTS From April 2008 to February 2011, a total of 190 patients with biopsy-proven IMN from 7 hospitals in China participated in the study. All patients had nephrotic syndrome with estimated glomerular filtration rate (eGFR) >30 mL/min/1.73 m(2). INTERVENTION Shenqi particle (9.6 g 3 times per day) or prednisone (1 mg/kg/d tapering to 0.17 mg/kg/d) and cyclophosphamide (total dose of 9-12 g per square meter of body surface area) for 48 weeks. OUTCOMES Primary outcomes included complete remission, defined as proteinuria (24-hour urine protein excretion) ≤0.3 g/d, or partial remission, defined as proteinuria with protein excretion >0.3-<3.5 g/d and a 50% reduction from its peak value at 48 weeks. Secondary outcomes included serum albumin level, eGFR, doubling of serum creatinine level, end-stage renal disease, and death. RESULTS Baseline values for proteinuria and eGFR were 5.34 ± 2.74 g/d and 84.0 ± 27.4 mL/min/1.73 m(2) for the Shenqi particle group and 5.33 ± 2.47 g/d and 83.8 ± 24.9 mL/min/1.73 m(2) for the control group, respectively. 132 patients (63 Shenqi particle group, 69 control group) completed the study. Change in urinary protein excretion in the Shenqi particle group was -3.01 (95% CI, -3.68 to -2.34) g/d, and in the control group, -3.28 (95% CI, -3.98 to -2.58) g/d; the mean difference between groups was 0.27 (95% CI, -0.70 to 1.23) g/d (P = 0.6). Changes in eGFR were 12.3 (95% CI, 4.99 to 19.6) mL/min/1.73 m(2) in the Shenqi particle group and -2.8 (95% CI, -10.32 to 4.77) mL/min/1.73 m(2) in the control group; the mean difference between groups was 15.1 (95% CI, 4.56 to 25.55) mL/min/1.73 m(2) (P = 0.005). Severe adverse events occurred in only the control group (14.5%) and included lung infection, liver injury, and pneumonia. LIMITATIONS High rate of loss to follow-up and lack of observation period prior to the study. CONCLUSIONS Shenqi particle may be a promising alternative therapy for adults with IMN and nephrotic syndrome.

Abstract
Background Peroxisome proliferator-activated receptor gamma (PPARγ) agonists are clinically used to counteract hyperglycemia. However, so far experienced unwanted side effects, such as weight gain, promote the search for new PPARγ activators. Methods We used a combination of in silico, in vitro, cell-based and in vivo models to identify and validate natural products as promising leads for partial novel PPARγ agonists. Results The natural product honokiol from the traditional Chinese herbal drug Magnolia bark was in silico predicted to bind into the PPARγ ligand binding pocket as dimer. Honokiol indeed directly bound to purified PPARγ ligand-binding domain (LBD) and acted as partial agonist in a PPARγ-mediated luciferase reporter assay. Honokiol was then directly compared to the clinically used full agonist pioglitazone with regard to stimulation of glucose uptake in adipocytes as well as adipogenic differentiation in 3T3-L1 pre-adipocytes and mouse embryonic fibroblasts. While honokiol stimulated basal glucose uptake to a similar extent as pioglitazone, it did not induce adipogenesis in contrast to pioglitazone. In diabetic KKAy mice oral application of honokiol prevented hyperglycemia and suppressed weight gain. Conclusion We identified honokiol as a partial non-adipogenic PPARγ agonist in vitro which prevented hyperglycemia and weight gain in vivo. General significance This observed activity profile suggests honokiol as promising new pharmaceutical lead or dietary supplement to combat metabolic disease, and provides a molecular explanation for the use of Magnolia in traditional medicine. Honokiol is identified and characterized as novel partial PPARγ agonist from nature. In cell models honokiol increases glucose uptake but is not adipogenic. In KKAy diabetic mice it decreases blood glucose and suppresses weight gain. PPARγ agonism of honokiol may explain the use of Magnolia bark in traditional medicine.

Abstract
Kidney-tonifying recipe can reduce the accumulation of advanced glycation end products, prevent neuronal degeneration and improve cognitive functions in ovariectomized rats. Radix Achyranthis Bidentatae alcohol extracts may dose-dependently inhibit non-enzymatic saccharification in vitro. This study aimed to examine the effect of Radix Achyranthis Bidentatae on advanced glycation end products and on learning and memory capabilities in ovariectomized rats. Ovariectomized rats were treated with Radix Achyranthis Bidentatae alcohol extracts (containing 1.5 g/kg crude drug) or 0.1% aminoguanidine for 12 weeks and behavioral testing was performed with the Y-electrical maze. This test revealed that Radix Achyranthis Bidentatae and aminoguanidine could improve the learning and memory capabilities of ovariectomized rats. Results of competitive enzyme-linked immunosorbent assay showed that treatment with Radix Achyranthis Bidentatae or aminoguanidine reduced the accumulation of advanced glycation end products in the frontal cortex of ovariectomized rats, while increasing content in the blood and urine. Biochemical tests showed that treatment with Radix Achyranthis Bidentatae or aminoguanidine decreased superoxide dismutase activity in the serum and frontal cortex, and increased serum levels of glutathione peroxidase in ovariectomized rats. In addition, there was no apparent effect on malondialdehyde levels. These experimental findings indicate that Radix Achyranthis Bidentatae inhibits production of advanced glycation end products and its accumulation in brain tissue, and improves learning and memory capabilities in ovariectomized rats. These effects may be associated with an anti-oxidative action of the extract.

A multicenter, randomized, double-blind, parallel-group, placebo-controlled study of the effects of qili qiangxin capsules in patients with chronic heart failure. J Am Coll Cardiol 2013; 62:1065-1072. [PMID: 23747768 DOI: 10.1016/j.jacc.2013.05.035] [Citation(s) in RCA: 210] [Impact Index Per Article: 19.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/17/2013] [Revised: 05/08/2013] [Accepted: 05/13/2013] [Indexed: 11/25/2022]
Abstract
OBJECTIVES The purpose of this study was to assess the effects of qili qiangxin capsules in patients with chronic heart failure (CHF). BACKGROUND Qili qiangxin capsules are a traditional Chinese medicine that has been approved in China for the treatment of CHF, but the evidence supporting its efficacy remains unclear. METHODS A total of 512 patients with CHF were enrolled and randomly assigned to receive the placebo or qili qiangxin capsules in addition to their standard medications for the treatment of CHF. The primary endpoint was the reduction or percent change in the plasma N-terminal pro-B-type natriuretic peptide (NT-proBNP) level during 12 weeks of treatment. RESULTS At the 12-week follow-up, a significant reduction in the NT-proBNP level from baseline was observed in both groups, but the qili qiangxin capsule group demonstrated a significantly greater reduction than the placebo group (p = 0.002); 47.95% of patients in the qili qiangxin capsule group demonstrated reductions in NT-proBNP levels of at least 30% compared with 31.98% of patients in the placebo group (p < 0.001). Treatment with qili qiangxin capsules also demonstrated superior performance in comparison to the placebo with respect to New York Heart Association functional classification, left ventricular ejection fraction, 6-min walking distance, and quality of life. CONCLUSIONS On a background of standard treatment, qili qiangxin capsules further reduced the levels of NT-proBNP. Together, our data suggest that qili qiangxin capsules could be used in combination therapy for CHF.

Abstract
Gastrodin, an active component of tall gastrodia tuber, is widely used in the treatment of dizziness, paralysis, epilepsy, stroke and dementia, and exhibits a neuroprotective effect. A rat model of spinal cord injury was established using Allen's method, and gastrodin was administered via the subarachnoid cavity and by intraperitoneal injection for 7 days. Results show that gastrodin promoted the secretion of brain-derived neurotrophic factor in rats with spinal cord injury. After gastrodin treatment, the maximum angle of the inclined plane test, and the Basso, Beattie and Bresnahan scores increased. Moreover, gastrodin improved neural tissue recovery in the injured spinal cord. These results demonstrate that gastrodin promotes the secretion of brain-derived neurotrophic factor, contributes to the recovery of neurological function, and protects neural cells against injury.

Abstract
BACKGROUND Preparations of the herb Tripterygium wilfordii Hook F are used widely for the treatment of chronic kidney disease in China. The efficacy and safety of Tripterygium preparations still have not been fully identified. STUDY DESIGN Systematic review and meta-analysis. SETTING & POPULATION Patients with chronic kidney disease. SELECTION CRITERIA FOR STUDIES Randomized controlled trials. INTERVENTION Tripterygium preparations (Tripterygium glycoside tablets, Tripterygium hypoglaucum Hutch tablets, and Tripterygium granules or extracts) versus placebo, standard care, or other immunosuppressive treatment. OUTCOMES Weighted mean difference and summary estimates of relative risk (RR) reductions with 95% CIs were calculated with a random-effects model. Outcomes analyzed included change in proteinuria, serum creatinine level, and creatinine clearance rate, as well as remission and relapse rate and drug-related adverse events. RESULTS We identified 75 trials that included 4,386 participants. Overall, Tripterygium therapy reduced proteinuria by protein excretion of 628 (95% CI, -736 to -521) mg/d and reduced serum creatinine level by 0.12 (95% CI, -0.17 to -0.06) mg/dL compared with controls (both P < 0.001) in a range of kidney conditions. Tripterygium preparations also increased the rate of complete remission by 56% (95% CI, 32%-85%; P < 0.001) and of complete or partial remission by 24% (95% CI, 17%-31%; P < 0.001) while reducing relapse by 58% (95% CI, 42%-69%; P < 0.001). Tripterygium preparations increased the rate of liver function test result abnormalities (RR, 4.03; 95% CI, 2.24-7.25; P < 0.001) and altered menstruation (RR, 5.29; 95% CI, 2.09-13.38; P < 0.001). LIMITATIONS Suboptimal study quality, significant heterogeneity in the primary outcome. CONCLUSIONS Tripterygium preparations may have nephroprotective effects, but high-quality trials are required to reliably determine the balance of benefits and harms.

Abstract
Suspended moxibustion-produced heat can transfer from the acupoint to other sites of the body. The suspended moxibustion should be terminated when clinical propagated sensation disappears, because this implies that the quantity of moxibustion is sufficient. We wanted to investigate if this phenomenon also occurs in experimental animals. In the present study, a rat model of stroke was established and treated with suspended moxibustion at Dazhui (DU14) for 60 minutes. Results showed that the increase in tail temperature began at 15 minutes after suspended moxibustion and decreased gradually at 40 minutes. In addition, neurological function was significantly improved in stroke rats with tail temperature increase following suspended moxibustion, and this effect was associated with significantly reduced tumor necrosis factor α and interleukin 1β mRNA. However, there was no significant difference between 40- and 60-minute suspended moxibustion. The findings indicate that elevated tail temperature began to decrease at 40 minutes after suspended moxibustion, and further suspended moxibustion was not useful in the recovery of stroke rats.

Abstract
Ninety-four patients with lumbar intervertebral disc herniation were enrolled in this study. Of these, 48 were treated with Feng's Spinal Manipulation, hot fomentation, and bed rest (treatment group). The remaining 46 patients were treated with hot fomentation and bed rest only (control group). After 3 weeks of treatment, clinical parameters including the angle of straight-leg raising, visual analogue scale pain score, and Japanese Orthopaedic Association score for low back pain were improved. The treatment group had significantly better improvement in scores than the control group. Magnetic resonance myelography three-dimensional reconstruction imaging of the vertebral canal demonstrated that filling of the compressed nerve root sleeve with cerebrospinal fluid increased significantly in the treatment group. The diameter of the nerve root sleeve was significantly larger in the treatment group than in the control group. However, the sagittal diameter index of the herniated nucleus pulposus and the angle between the nerve root sleeve and the thecal sac did not change significantly in either the treatment or control groups. The effectiveness of Feng's Spinal Manipulation for the treatment of symptoms associated with lumbar intervertebral disc herniation may be attributable to the relief of nerve root compression, without affecting the herniated nucleus pulposus or changing the morphology or position of the nerve root.

Abstract
Ulcerative colitis (UC) is a major form of inflammatory bowel disease (IBD), which is tightly regulated by the nuclear factor κB (NF-κB) pathway. Thus, the suppression of NF-κB signaling may provide a promising strategy for the treatment of UC. Qing Hua Chang Yin (QHCY) is a traditional Chinese formulation, which has been used for a number of years to clinically treat UC. However, little is known with regard to its anti-inflammatory properties. In the present study, lipopolysaccharide (LPS)-stimulated Caco-2 cells were used as an in vitro inflammatory model of the human intestinal epithelium to evaluate the anti-inflammatory effects of QHCY and its underlying molecular mechanisms. We observed that QHCY inhibited the inflammatory response in intestinal epithelial cells as it significantly and concentration-dependently reduced the LPS-induced secretion of pro-inflammatory TNF-α and IL-8 in Caco-2 cells. Furthermore, QHCY treatment inhibited the phosphorylation of IκB and the nuclear translocation of NF-κB in Caco-2 cells in a concentration-dependent manner, indicating that QHCY suppressed the activation of the NF-κB signaling pathway. Collectively, our results suggest that the inhibition of NF-κB-mediated inflammation may constitute a potential mechanism by which QHCY treats UC.

Abstract
A total of 30 students scoring between 12 and 20 on the Test Anxiety Scale who had been exhibiting an anxious state > 24 hours, and 30 normal control students were recruited. Indices of heart rate variability were recorded using an Actiheart electrocardiogram recorder at 10 minutes before auricular pressing, in the first half of stimulation and in the second half of stimulation. The results revealed that the standard deviation of all normal to normal intervals and the root mean square of standard deviation of normal to normal intervals were significantly increased after stimulation. The heart rate variability triangular index, very-low-frequency power, low-frequency power, and the ratio of low-frequency to high-frequency power were increased to different degrees after stimulation. Compared with normal controls, the root mean square of standard deviation of normal to normal intervals was significantly increased in anxious students following auricular pressing. These results indicated that auricular pressing can elevate heart rate variability, especially the root mean square of standard deviation of normal to normal intervals in students with pre-exam anxiety.

Abstract
Traditional Chinese medicine (TCM) has been demonstrated to have potent cytotoxic activity against certain malignant tumors. Ionizing radiation (IR) is one of the most effective methods used in the clinical treatment of cancer. The drawback of a single formula is that it limits the treatment efficacy for cancer, while comprehensive strategies require additional theoretical support. However, a combination of different antitumor treatment modalities is advantageous in restricting the non-specific toxicity often observed with an extremely high dose of a single regimen. The induction of apoptotic cell death is a significant process in tumor cells following radiotherapy or chemotherapy, and resistance to these treatments has been linked to a low propensity for apoptosis. Autophagy is a response of cancer cells to IR or chemotherapy, and involves the prominent formation of autophagic vacuoles in the cytoplasm. In this review, the synergistic effects of TCM and radiotherapy are summarized and the underlying mechanisms are illustrated, providing new therapeutic strategies for cancer.

Abstract
Erhuang capsule, a typical formula based on traditional Chinese medicine theory, is widely used to ameliorate multiple sclerosis, inflammation and side effects of glucocorticoid treatment. Oligodendrocyte precursor cells are neural stem cells that are important for myelin repair and regeneration. In the present study, Erhuang capsule effectively improved clinical symptoms and neurological function scores, reduced mortality and promoted recovery of neurological functions of mice with experimental autoimmune encephalomyelitis. The mechanism of action involved significant increases in oligodendrocyte precursor cell proliferation in specific regions of the brain and spinal cord, increased oligodendrocyte lineage gene 2 expression and enhanced oligodendrocyte precursor cell differentiation.

Abstract
One hundred patients with focal epilepsy were recruited for the present study and their seizures controlled with antiepileptic drugs. The patients then orally received a capsule of tall gastrodis tuber powder, a traditional Chinese drug, and underwent single photon emission computed tomography, long-term electroencephalogram, and CT/MRI. Blood drug levels were monitored throughout the study. Before treatment with tall gastrodis tuber, 35 of the 100 cases had abnormal CT/MRI scans; 79 cases had abnormal single photon emission computed tomography images; 86 cases had abnormal electroencephalogram; and a total of 146 abnormal perfusion foci were observed across the 100 subjects. After treatment, the number of patients with normal single photon emission computed tomography images increased by 12; normal electroencephalogram was observed in an additional 27 cases and the number of patients with epileptiform discharge decreased by 29 (34% of 86); the total number of abnormal perfusion foci decreased by 52 (36%) and changes in abnormal foci were visible in 65 patients. These changes indicate that the administration of tall gastrodis tuber in combination with antiepileptic drugs repairs abnormal perfusion foci in patients with focal epilepsy. Our results demonstrate that traditional Chinese drugs can repair abnormal perfusion foci and, as such, are a promising new pathway in the treatment of focal epilepsy.
