RESUMO

A randomized, double-blind, placebo-controlled, multi-center phase Ⅱ clinical trial design was used in this study to recruit subjects who were in line with the syndrome of excess heat and fire toxin, and were diagnosed as recurrent oral ulcers, gingivitis, and acute pharyngitis. A total of 240 cases were included and randomly divided into a placebo group and a Huanglian Jiedu Pills group. The clinical efficacy of Huanglian Jiedu Pills in treating the syndrome of excess heat and fire toxin was evaluated by using the traditional Chinese medicine(TCM) syndrome scale. Enzyme-linked immunosorbent assay(ELISA) was used to determine and evaluate the levels of adenosine triphosphate(ATP), 4-hydroxynonenal(4-HNE), and adrenocorticotropic hormone(ACTH) in plasma of the two groups before and after administration and to predict their application value as clinical biomarkers. The results showed that the disappearance rate of main symptoms in the Huanglian Jiedu Pills group was 69.17%, and that in the placebo group was 50.83%. The comparison between the Huanglian Jiedu Pills group and the placebo group showed that 4-HNE before and after administration was statistically significant(P<0.05). The content of 4-HNE in the Huanglian Jiedu Pills group decreased significantly after administration(P<0.05), but that in the placebo group had no statistical significance and showed an upward trend. After administration, the content of ATP in both Huanglian Jiedu Pills group and placebo group decreased significantly(P<0.05), indicating that the energy metabolism disorder was significantly improved after administration of Huanglian Jiedu Pills and the body's self-healing ability also alleviated the increase in ATP level caused by the syndrome of excess heat and fire toxin to a certain extent. ACTH in both Huanglian Jiedu Pills group and placebo group decreased significantly after administration(P<0.05). It is concluded that Huanglian Jiedu Pills has a significant clinical effect, and can significantly improve the abnormal levels of ATP and 4-HNE in plasma caused by the syndrome of excess heat and fire toxin, which are speculated to be the effective clinical biomarkers for Huanglian Jiedu Pills to treat the syndrome of excess heat and fire toxin.

RESUMO

Quality evaluation of Chinese medicinal decoction pieces is vital for the development of the downstream industries, and is an important channel for implementing the strategy of "higher quality, higher price, and priority for the high quality" for traditional Chinese medicine. At the moment, the quality of Chinese medicinal decoction pieces is mainly evaluated based on chemical component examination. Considering the weak preliminary research foundation and poor research conditions, traditional experience-based evaluation is undervalued in the quality rating of Chinese medicinal decoction pieces. However, traditional experience is a summary of the quality of Chinese medicinal materials based on clinical experience, which thus can be a potential basis for the quality evaluation of the decoction pieces. It is a challenge in the evaluation of Chinese medicinal decoction pieces to objectify the traditional experience-based evaluation from multiple aspects such as chemistry, effect, and characterization via modern techniques. Therefore, this study developed the "experience-ingredients-activity-electronic sensing" evaluation system for Chinese medicinal decoction pieces on the basis of experience-based assessment, chemical ingredients that can truly reflect the traditional experience, biological effect assessment, and electronic sensory evaluation, which is expected to quantify the traditional experience of quality evaluation of Chinese medicinal decoction pieces via chemistry, biology, and sensory simulation. The evaluation system can serve as a reference for clinical experience-based quality evaluation of Chinese medicinal decoction pieces.

RESUMO

Qingxin Lianzi Yin (QXLZY), as an ancient classical formula for clearing the heart and nourishing the Yin, was composed of nine herbs (Scutellariae Radix, Ophiopogonis Radix, Lycii Cortex, Plantaginis Semen, Glycyrrhizae Radix et Rhizoma Praeparata Cum Melle, Nelumbinis Semen, Poria, Astragali Radix and Ginseng Radix et Rhizoma), coming from Prescriptions of the Bureau of Taiping People's Welfare Pharmacy. It could clear away the heart-fire, promote the interaction of the heart and kidney, replenish Qi and Yin, and stop strangury-turbidity. It was used to treat gonorrhea of urination, seminal emission, restlessness, wasting-thirst and so on. At present, the usage and dosage of QXLZY and its addition and subtraction are different in clinical practice. Most of the studies just focus on its clinical efficacy, and there is few review literature reflecting its historical evolution. Based on this, this paper systematically clarified the historical evolution, composition, preparation, interpretation, function, and modern clinical application of QXLZY. This work has been explained the historical evolution of QXLZY, and found that it was wildly used in modern clinical, especially suitable for the treatment of chronic urinary system diseases. At the same time, QXLZY also had significant therapeutic effects on neurasthenia, stomatitis, diabetic nephropathy and other aspects. Through the comprehensive analysis of ancient and modern literature, this work explores the true connotation of QXLZY from the perspective of traditional Chinese medicine theory, which can point out the direction of the clinical application and positioning of this famous classical formula after it comes into the market, and also can provide reference basis for its subsequent in-depth research and development.

RESUMO

In this study, chemistry, biology and pharmacology were combinated to screen pseudoallergenic substances of Shuang-huanglian injection (SHLI) so that to establish a scientific and systematic approach to screen pseudoallergenic substances of traditional Chinese medicine injections. The mouse pseudoallergic reaction models were used to screen the pseudoallergic reaction of SHLI's intermediate extract and the intermediate extract's component or ingredient. Among the three intermediates of Shuanghuanglian injection (extract of Scutellaria baicalensis, extract of Lonicera japonica, extract of Forsythia suspensa) , pseudoallergic action of Forsythia suspensa was the strongest, Forsythia suspesnsa's pseudoallergic reaction mainly associated with the composition with largerchemical polarity. Further it was found that forsythiaside A and arctiin which existed in the the composition with largerchemical polarity caused obvious pseudoallergic reactions. SHLI with removal forsythoside A with the technology of HPLC-MS displayed reduced pseudoallergic reaction and a significant improved safety. This study provided a scientific basis for SHLI process improvements and also offered idea and research foundation for screening pseudoallergenic substances injections in other TCM injections.

<p><b>OBJECTIVE</b>To observe the protective effects of the Huanglian Jiedu decoction aqueous extract and its active fraction, which consists of total alkaloids, total flavonoids and total iridoid, on the thalamus of cerebral ischemia in rats.</p><p><b>METHOD</b>The rat model of middle cerebral artery occlusion (MCAO) was chosen. Male SD rats were randomly divided into sham-operation group, model group, aqueous extract group (800 mg x kg(-1)), total alkaloids group(44 mg x kg(-1)), total flavonoids group (50 mg x kg(-1)) and the total iridoid group (80 mg x kg(-1)). The rats were administered the appropriate drugs intragastrically once a day, for 7 days after surgery. An equivalent volume of saline was given in the sham surgery and model groups. The HE staining was adopted to observe the pathological changes. Determination of Glu and gamma-GABA in thalamus were detected by HPLC with fluorescence detection. The expression of GAD65 was examined with immunohistochemistry and double staining with uorescent-conjugated antibodies against GFAP and Cx43 was chosen in this study.</p><p><b>RESULT</b>The neurons degenerated in MCAO rats after cerebral ischemia 7 d. The content of Glu, gamma-GABA decreased (P < 0.05), the expression of GAD65 reduced (P < 0.05) and the expression of GFAP and Cx43 increased (P < 0.01) in thalamus of rats compared with sham-operation group. Huanglian Jiedu decoction aqueous extract, total alkaloids, total flavonoids and total iridoid reduced the degeneration of neurons. Total flavonoids could promote the expression of GAD65 (P < 0.05) and decrease the expression of GFAP and Cx43 (P < 0.01) in thalamus compared with model group while it could also increased the content of Glu,gamma-GA BA to normal levels. Compared with model group, Huanglian Jiedu decoction aqueous extract, total alkaloids and total iridoid could raise the expression of Cx43, and Huanglian Jiedu decoction aqueous extract could also increase the expression of GAD65 (P < 0.05). The expression of GFAP in Huanglian Jiedu decoction aqueous extract group, total alkaloids group and total iridoid group were not different compared with model group while the content of gamma-GABA decreased (P < 0.05) compared with sham-operation group.</p><p><b>CONCLUSION</b>The degeneration of nerve cells, the reduction of neurotransmitter amino acids content, the aberrant activation of astrocytes and the abnormal expression of GFAP and Cx43 will appear in thalamus of MCAO rats after ischemia. Huanglian Jiedu decoction total flavonoids could relieve the injury of nerve cell through inhibiting the abnormal activation of astrocytes and regulating the expression of GFAP and GAD65.</p>

RESUMO

Cinobufacini is an aqueous extract of Bufo bufo gargarizans Cantor dried skin, which has been widely used for cancer therapy in China. So far, its active components are still not very clear. In previous reports, bufadienolides with low-concentration were usually studied because of their anticancer effects. However, the high polarity constituents in cinobufacini are less investigated. The present study found that more than 50% contents of cinobufacini were water-soluble peptides. Then, in vitro anticancer experiments were carried out, including human stomach cancer cell lines BGC823 and MCG803, human colon cancer cell lines DLD-1 and HT-29, and human pancreatic cancer cell line MIAPACA-2. The IC50 for these cell lines model were ranged from 25-123 microgmL(-1). The results indicated that these peptides showed similar activity with cinobufacini injection. As a conclusion, this study provides a new and further understanding of anticancer components in cinobufacini injection.

RESUMO

Rheumatoid arthritis (RA) is characterized as a chronic inflammatory disease in joints and concomitant destruction of cartilage and bone. Cartilage extracellular matrix components, such as type II collagen and aggrecan are enzymatically degraded by matrix metalloproteinases (MMPs) and aggrecanases in RA. Currently, treatments targeting cytokines, including anti-tumor necrosis factor (TNF) α antibodies, soluble TNF receptor, anti-interleukin (IL)-6 receptor antibody, and IL-1 receptor antagonist, are widely used for treating RA in addition to antiantiinflammatory agents and disease-modifying antirheumatic drugs (DMARDs), such as inflmethotrexate, but these treatments have some problems, especially in terms of cost and the increased susceptibility of patients to infection in addition to the existence of low-responders to these treatments. Therefore, therapeutics that can be safely used for an extended period of time would be preferable. Complementary and alternative medicines including traditional Chinese medicines (TCM) have been used for the arthritic diseases through the ages. Recently, there are many reports concerning the anti-arthritic action mechanisms of TCM-based herbal formulas and crude herbal extracts or isolated ingredients. These natural herbal medicines are thought to moderately improve RA, but they exert various actions for the treatment of RA. In this review, the current status of the mechanism exploration of natural compounds and TCM-based herbal formulas are summarized, focusing on the protection of cartilage destruction in arthritic diseases including RA and osteoarthritis.
