Relationship Between Traditional Chinese Medicine(TCM)Constitution and TCM Syndrome in the Diagnosis and Treatment of Chronic Diseases.

Chronic diseases are global threats to human health. By applying the traditional Chinese medicine (TCM) theory of body constitution to the treatment of chronic diseases, and comprehensively identifying and differentiating the syndrome, disease, and constitution, TCM can be fully used in the diagnosis and treatment of chronic diseases. In this manner, population-based and evidence-based modern medicine can organically align with the individual-focused and speculation-based TCM, with subsequent benefits for the control of chronic diseases, reducing their burden on human health.

Sophocarpine Protects Mice from ConA-Induced Hepatitis via Inhibition of the IFN-Gamma/STAT1 Pathway.

Sophocarpine is the major pharmacologically active compound of the traditional Chinese herbal medicine Radix Sophorae Subprostratae which has been used in treating hepatitis for years in China. It has been demonstrated that Sophocarpine exerts an activity in immune modulation and significantly decreases the production of inflammatory cytokines. However, the protective effects of Sophocarpine in T cell-dependent immune hepatitis remained unknown. The aim of this study was to determine the protective effects and pharmacological mechanisms of Sophocarpine on Concanavalin A (ConA)-induced hepatitis, an experimental model of T cell-mediated liver injury. BALB/C mice were pretreated with Sophocarpine or Bicyclol for five consecutive days. Thirty minutes after the final administration, the mice were injected with 15 mg⋅kg-1 of ConA intravenously. The results indicated that pretreatment with Sophocarpine significantly ameliorated liver inflammation and injury as evidenced by both biochemical and histopathological observations. Moreover, in Sophocarpine-pretreated mice, liver messenger RNA expression levels of chemokines and adhesion molecules, such as macrophage inflammatory protein-1α, CXC chemokine ligand 10, and Intercellular adhesion molecule-1, were markedly reduced. Further studies revealed that Sophocarpine significantly downregulated the expression of T-bet via inhibition of signal transducers and activators of transcription1 (STAT1) activation and overexpression of suppressor of cytokine signaling1, inhibiting the activation of Th1 cells and the expression of Interferon-γ (IFN-γ). Altogether, these results suggest new opportunities to use Sophocarpine in the treatment of T cell-mediated liver disease. In summary, Sophocarpine could attenuate ConA-induced liver injury, and the protective effect of Sophocarpine was associated with its inhibition effect of pro-inflammatory cytokines, chemokines, and the IFN-γ/STAT1 signaling pathway.

[Protective effects of Liuwei Wuling tablet on acute alcoholic-induced liver injury in mice].

The protective action and the relevant mechanism of Liuwei Wuling tablet on acute alcoholic hepatic injury in mice were investigated. All the C57BL/6 mice were divided randomly into 7 groups including blank, model, bifendate (150 mg•kg⁻¹, positive control) and experimental groups consisted of extremely low dose (0.1 g•kg⁻¹), low (0.5 g•kg⁻¹), upper (4 g•kg⁻¹) and high dose (8 g•kg⁻¹) of Liuwei Wuling tablet groups. The acute liver injury model was induced by modified method that the model, positive control and experimental groups were orally administrated 56% alcohol (6 g•kg⁻¹) twice at 12 hour intervals on the fifth day after drugs administration. After 12 hours, the mice were sacrificed to contribute blood and liver for biochemical and histological examinations. Compared with the model, the activities of ALT and AST in serum decreased significantly in different Liuwei Wuling tablet groups. Meanwhile, in liver tissue, the levels of TG, MDA, TNF-α and IL-1ß reduced obviously while the GSH and SOD activities showed markedly increase with a dose-dependent manner. Correspondingly, the microscopically pathological differences of the liver tissue observed by HE and oil red O staining indicated that the liver cell swelling, hydropic degeneration and lipid droplets formation induced by alcohol were significantly improved, which suggested the Liuwei Wuling tablet can reduce the liver injure. In conclusion, the Liuwei Wuling tablet had the protective effect on acute alcoholic hepatic injury which maybe depended on the mechanism of relieving lipid peroxidation, elevating antioxidant enzymes activity, inhibiting oxidative stress and reducing inflammation factors expression.

[Protective effects of luteolin against acetaminophen-induced damage in L02 liver cells].

This paper was aimed to investigate the protective effects of luteolin (Lut) against acetaminophen（APAP）-induced damage in L02 liver cells. CCK-8 was used to detect the cell activation of L02 cells treated by different Lut. The concentration and time of APAP induced L02 cell damage was screened. The effect of Lut on APAP induced apoptosis of L02 cells was detected by cell morphological observation, CCK-8 assay and flow cytometry. The contents of MDA, GSH and SOD activity in cell supernatant were detected by colorimetric assay. The expression of apoptosis-related genes Bax, Bcl-2 and caspase-3 was detected by RT-PCR. The results showed that Lut in 2.5-40 µmol•L⁻¹ range does not affect the activity of L02 cells; 12 mmol•L⁻¹ APAP incubated with L02 cell 12 h to establish damage model. Compared with the model group, the cell status of Lut group was significantly improved, the cell body was increased, the adherence ability was recovered, and the apoptosis rate was obviously decreased. MDA content decreased significantly (P<0.05, P<0.01), GSH and SOD activity significantly increased (P<0.05, P<0.01), at the same time, it could up-regulate expression of Bcl-2 mRNA and down-regulate the expression of Bax and caspase-3 mRNA. In conclusion,Lut has protective effect on APAP induced L02 cell injury, and its mechanism may be related to the reduction of oxidative stress and inhibition of apoptosis.

[Protective effects of oxymatrine against H2O2-induced damage in L02 cells].

To investigate the protective effects of oxymatrine (OMT) against H2O2-induced damage in L02 cells and research the mechanism,L02 cells were used as the research object. The oxidative stress model of L02 was established by hydrogen peroxide (H2O2). CCK-8 was used to detect the cell activation of L02 cells treated by different OMT. FCM (flow cytometry) assay was used to evaluate the cell proliferation of L02 cells treated by OMT. The apoptosis of L02 cells was detected using Annexin-V/7-AAD apoptosis detection kit. The level of ROS was detected by DCFH-DA fluorescence probe. The GSH-PX and SOD were detected by micro plate and colorimetric method. Results showed that when the concentration of OMT is between 6.25 and 100 mg•L⁻¹, it could promote the production of NADPH and strengthen the activity of GSH-PX and SOD to get rid of the ROS to protect the L02 cell from the apoptosis of L02 cell induced by H2O2.

Efficacy of Compound Kushen Injection in Relieving Cancer-Related Pain: A Systematic Review and Meta-Analysis.

Despite widespread popular use of complementary and alternative medicine (CAM) therapies, a rigorous evidence based on the efficacy of compound kushen injection (CKI) for cancer-related pain is lacking. In this study, we evaluated the efficacy and safety of compound kushen injection and provided information for current or future research and clinical application. Sixteen trials were identified with a total of 1564 patients. The total pain relief rate of CKI plus chemotherapy is better than chemotherapy except for colorectal cancer. The treatment groups achieved a reduction in the incidences of leukopenia and gastrointestinal, hepatic, and renal functional lesion. However, there is paucity of multi-institutional RCTs evaluating compound kushen injection for cancer pain with adequate power, duration, and sham control. The quantity and quality of RCTs are lower so that we still have to boost the research level through scientific design and normative report.
