Scutellariae Radix is a kind of traditional Chinese medicine, which has the functions of heat-clearing and damp-drying, purging fire and detoxifying, hemostasis and miscarriage prevention. Modern pharmacological studies show that Scutellariae Radix has various effects, such as anti-oxidation, anti-inflammatory, liver protection and antiviral microorganisms. By searching the documents in the past ten years, the author has found that Scutellariae Radix and its active components play an important role in protecting the liver. It can prevent and cure liver injuries caused by different reasons, including acute or chronic hepatitis, liver fibrosis and liver cancer. Among all kinds(chemical, immunological, alcoholic, nonalcoholic, viral, ischemia-reperfusion, etc.) of acute or chronic hepatitis, most studies are on CCl_4 induced chemical liver injury. Scutellariae Radix and its active components can significantly reduce the serum transaminase level in hepatitis animals, and reduce the degree of liver pathological damage. The mechanisms include antioxidant stress, anti-inflammatory, anti-apoptosis, inhibition of immunity, anti-virus and regulation of lipid metabolism, etc. Scutellariae Radix and its active components can significantly inhibit the activation of hepatic stellate cells and reduce extracellular matrix, and its anti-fibrosis mechanism involves antioxidation, anti-inflammatory, inducing apoptosis of hepatic stellate cells and so on. Whether in vivo or in vitro, Scutellariae Radix and its active components show a good anti-hepatocarcinoma effect, especially on hepatocarcinoma. Its prevention and treatment mechanisms for hepatocarcinoma mainly include blocking cancer cell cycle, inhibiting cancer cell metastasis, promoting cancer cell apoptosis and inducing autophagy. It can be seen that Scutellariae Radix has multiple functions and mechanisms in liver protection, and has a great development potential. Therefore, this paper reviews the prevention and treatment effects and mechanism of Scutellariae Radix and its components on different liver diseases, in order to provide reference for in-depth study, development and clinical application in the prevention and treatment of liver disease.

Objective To explore the effect of repaglinide intensive treatment on islet β-cell function and long-term control of blood glucose in newly diagnosed type 2 diabetic patients. Methods Self-control and inter-group control prospective study was conducted in 80 newly diagnosed type 2 diabetic patients who were treated with short-term repaglinide intensive treatment and islet β-cell function was assessed by 75 g oral glucose tolerance test (OGTT) before and after repaglinide treatment. The changes of △I30/△G30 ratio, blood lipid, HOMA A and HOMA B were examined. Results After treatment, in successful group, middle group and defeat group, the fasting plasma glucose levels were decreased from 8.9±1.5, 8.6±1.6,9.0±2.0 to 5.0±1.4,6.3±0. 7,6.5±0. 9 mmol/L, 0. 5 h postprandial glucose levels were decreased from (12.6±1.6, 12.6±1.5, 12.4±1.3 to 8.4±1.0, 6.8±0. 7, 8. 6±0. 9)mmol/L,and 2 h postprandial glucose levels were decreased from (13.0±1.2, 13. 1±1.3, 13. 3±1.4 to 9.2±0.9, 6.6±0. 7, 9.2±0. 9)mmol/L,respectively (all P <0. 005). The ratio of △I30/△G30 was increased froml. 69±0. 31, 1.72±0. 33, 1.79±0. 36 to 4. 47±0. 62, 4. 42±0.46,12. 00±0.46 in the three groups, respectively (P<0.05). HOMA B was significantly improved (P<0. 05), while triglycerides and HOMA A were decreased(P<0. 05). The levels of fasting blood glucose and postprandial blood glucose in 21 patients were maintained within normal range for more than six months. There were significant differences in the ratio of △I30/△G30, age, repaglinide dosage and the time of reaching target of glucose [4.47±0.62 vs. 2. 0± 0.46; 39±8 vs. 56±9; 2.0±1.5 vs. 5.0±2.5; 32.4±8.0 vs. 53.3±7.6; all P<0.05] between successful group and defeat group. Conclusions The short-term intensive treatment with repaglinide can significantly improve the early secretion phase of insulin and the islet β-cell function, reconstruct of the physiological model of insulin secretion and relieve the disease.

Objective: This study is designed to investigate the effect and mechanism of Pingkui enema in treatment of ulcerative colitis. Methods: Sixty SD rats at SPF level were randomly divided into 6 groups which were normal group, model group, and the low, medium and high dose groups of Chinese medicine Pingkui enema, and sulfasalazine (SASP) enema group. The normal group and model group were given an equal volume of saline enema after modeling. After continuous administration for 10 days, the histopathological effects were evaluated after extraction, and the serum interleukin-8 (IL-8), interleukin-13 (IL-13), tumor necrosis factor (TNF-α), rat intestinal mucosal bifidobacteria adhesion and adhesin receptor were measured by enzyme-linked immunosorbent assay (ELISA). The real-time fluorescence quantitative PCR (RT-PCR) were used to detect the intestinal bifidobacterial content. Results: Compared with the model group, the content of IL-8 (153.50 ± 8.59 pg/ml, 150.84 ± 5.38 pg/ml vs. 167.13 ± 13.66 pg/ml), TNF-α (330.08 ± 10.02 pg/ml, 287.27 ± 13.89 pg/ml vs. 376.50 ± 19.06 pg/ml) in medium, high dose group of Pingkui enema significantly decreased (P<0.05), while the IL-13 (37.04 ± 3.62 pg/ml, 40.64 ± 5.98 pg/ml vs. 31.57 ± 2.95 pg/ml) significantly increased (P<0.05). The bifidobacteria adhesin (124.84 ± 9.74 ng/L, 149.93 ± 9.57 ng/L, 176.74 ± 11.01 ng/L vs. 101.11 ± 17.18 ng/L) and adhesin receptor (78.44 ± 14.03 ng/L, 99.50 ± 3.63 ng/L, 107.36 ± 5.05 ng/L vs. 60.96 ± 13.89 ng/L) in low-, medium-, high dose group of Pingkui enema significantly increased (P<0.05). The content of bifidobacteria (1 331.4 ± 242.2 copies/μl vs. 490.5 ± 106.0 copies/μl) in the middle dose Pingkui enema group significantly increased (P<0.05). Conclusions The Pingkui enema can promote the colonization of intestinal epithelial cells by promoting bifidobacteria, increase bifidobacterium adhesin and adhesin receptors, up-regulate the expression of IL-13, and down-regulate the expression of IL-8, TNF-α.
