OBJECTIVE: To observe the immediate effect and safety of Shexiang Tongxin dropping pills (, STDP) on patients with coronary slow flow (CSF), and furthermore, to explore new evidence for the use of Chinese medicine in treating ischemic chest pain. METHODS: Coronary angiography (CAG) with corrected thrombolysis in myocardial infarction (TIMI) frame count (CTFC) was applied (collected at 30 frames/s). The treatment group included 22 CSF patients, while the control group included 22 individuals with normal coronary flow. CSF patients were given 4 STDP through sublingual administration, and CAG was performed 5 min after the medication. The immediate blood flow frame count, blood pressure, and heart rate of patients before and after the use of STDP were compared. The liver and kidney functions of patients were examined before and after treatments. RESULTS: There was a significant difference in CTFC between groups (P<0.05). The average CTFC values of the vessels with slow blood flow in CSF patients were, respectively, 49.98 ± 10.01 and 40.42 ± 11.33 before and after the treatment with STDP, a 19.13% improvement. The CTFC values (frame/s) measured before and after treatment at the left anterior descending coronary artery, left circumflex artery, and right coronary artery were, respectively, 48.00 ± 13.32 and 41.80 ± 15.38, 59.00 ± 4.69 and 50.00 ± 9.04, and 51.90 ± 8.40 and 40.09 ± 10.46, giving 12.92%, 15.25%, and 22.76% improvements, respectively. The CTFC values of vessels with slow flow before treatment were significantly decreased after treatment (P<0.05). There were no apparent changes in the heart rate, blood pressure, or liver or kidney function of CSF patients after treatment with STDP (all P>0.05). CONCLUSIONS The immediate effect of STDP in treating CSF patients was apparent. This medication could significantly improve coronary flow without affecting blood pressure or heart rate. Our findings support the potential of Chinese medicine to treat ischemic chest pain.

OBJECTIVE: To investigate the mechanism of inflflammatory-mediated toll-like receptor 4 (TLR4)-p38 mitogen-activated protein kinase (p38 MAPK) pathway in Kupffer cells (KCs) of non-alcoholic steatohepatitis (NASH) rats and the intervention effect of soothing Gan (Liver) and invigorating Pi (Spleen) recipes on this pathway. METHODS: After 1 week of acclimatization, 120 Sprague-Dawley male rats were randomly divided into 8 groups using a random number table (n=15 per group): normal group, model group, low-dose Chaihu Shugan Powder (, CHSG) group (3.2 g/kg), high-dose CHSG group (9.6 g/kg), low-dose Shenling Baizhu Powder (, SLBZ) group (10 g/kg), high-dose SLBZ (30 g/kg) group, and low- and highdose integrated recipe (L-IR, H-IR) groups. All rats in the model and treatment groups were fed with a high-fat diet (HFD). The treatments were administrated by gastrogavage once daily and lasted for 26 weeks. The liver tissues were detected with hematoxylin-eosin (HE) and oil red O staining. Levels of liver lipids, serum lipids and transaminases were measured. KCs were isolated from the livers of rats to evaluate the mRNA expressions of TLR4 and p38 MAPK by real-time flfluorescence quantitative polymerase chain reaction, and proteins expressions of TLR4, p-p38 MAPK and p38 MAPK by Western blot. Levels of inflammatory cytokines including tumor necrosis factor α (TNF-α), interleukin (IL)-1 and IL-6 in KCs were measured by enzyme-linked immunosorbent assay. RESULTS: After 26 weeks of HFD feeding, HE and oil red O staining showed that the NASH model rats successfully reproduced typical pathogenesis and histopathological features. Compared with the normal group, the model group exhibited significant increases in body weight, liver weight, liver index, serum levels of total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol, and aspartate aminotransferase as well as TC and TG levels in liver tissues, and significant decrease in serum level of high-density lipoprotein cholesterol (Plt;0.05 or Plt;0.01), while those indices were significantly ameliorated in the H-IR group (Plt;0.05 or Plt;0.01). Higher levels of TNF-α, IL-1 and IL-6 in KCs were observed in the model group compared with the normal group (Plt;0.01). Significant decreases in TNF-α, IL-1 and IL-6 were observed in the H-SLBZ, H-IR and L-IR groups compared with the model group (Plt;0.05 or Plt;0.01). The mRNA expressions of TLR4 and p38 MAPK and protein expressions of TLR4, p38 MAPK and p-p38 MAPK in KCs in the model group were significantly higher than the normal group (Plt;0.01), while those expression levels in the L-IR and H-IR groups were significantly lower than the model group (Plt;0.05 or Plt;0.01). CONCLUSION Inflflammation in KCs might play an important role in the pathogenesis of NASH in rats. The data demonstrated the importance of TLR4-p38MAPK signaling pathway in KCs for the anti-inflflammatory effect of soothing Gan and invigorating Pi recipes.

OBJECTIVE: The present study aims at determining the stability of a popular type 2 diabetes rat model induced by a high-fat diet combined with a low-dose streptozotocin injection. METHODS: Wistar rats were fed with a high-fat diet for 8 weeks followed by a one-time injection of 25 or 35 mg/kg streptozotocin to induce type 2 diabetes. Then the diabetic rats were fed with regular diet/high-fat diet for 4 weeks. Changes in biochemical parameters were monitored during the 4 weeks. RESULTS: All the rats developed more severe dyslipidemia and hepatic dysfunction after streptozotocin injection. The features of 35 mg/kg streptozotocin rats more resembled type 1 diabetes with decreased body weight and blood insulin. Rats with 25 mg/kg streptozotocin followed by normal diet feeding showed normalized blood glucose level and pancreatic structure, indicating that normal diet might help recovery from certain symptoms of type 2 diabetes. In comparison, diabetic rats fed with high-fat diet presented decreased but relatively stable blood glucose level, and this was significantly higher than that of the control group (P<0.05). CONCLUSIONS This model easily recovers with normal diet feeding. A high-fat diet is suggested as the background diet in future pharmacological studies using this model.

The present study was designed to evaluate protective activity of an ethanol extract of the stems of Schisandra chinensis (SCE) and explore its possible molecular mechanisms on acetaminophen (APAP) induced hepatotoxicity in a mouse model. The results of HPLC analysis showed that the main components of SCE included schisandrol A, schisandrol B, deoxyschisandrin, schisandrin B, and schisandrin C and their contents were 5.83, 7.11, 2.13, 4.86, 0.42 mg·g, respectively. SCE extract was given for 7 consecutive days before a single hepatotoxic dose of APAP (250 mg·kg) was injected to mice. Our results showed that SCE pretreatment ameliorated liver dysfunction and oxidative stress, which was evidenced by significant decreases in aspartate transaminase (AST), alanine aminotransferase (ALT), malondialdehyde (MDA) contents and elevations in reduced glutathione (GSH) and superoxide dismutase (SOD) levels. These findings were associated with the result that the SCE pretreatment significantly decreased expression levels of 4-hydroxynonenal (4-HNE) and 3-nitrotyrosine (3-NT). SCE also significantly decreased the expression levels of Bax, mitogen- activated protein kinase (MAPK), and cleaved caspase-3 by APAP exposure. Furthermore, supplementation with SCE suppressed the expression levels of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2), suggesting alleviation of inflammatory response. In summary, these findings from the present study clearly demonstrated that SCE exerted significant alleviation in APAP-induced oxidative stress, inflammation and apoptosis mainly via regulating MAPK and caspase-3 signaling pathways.

Nonalcoholic fatty liver disease (NAFLD) and type 2 Diabetes Mellitus (T2DM) are highly prevalent diseases and are closely associated, with NAFLD being present in the majority of T2DM patients. In Asian traditional medicine, Mori Cortex is widely used for the treatment of diabetes and hyperlipidemia. However, whether it has a therapeutic effect on T2DM associated with NAFLD is still unknown. The present study showed that the oral treatment with Mori Cortex extract (MCE; 10 g·kg·d) lowered the blood lipid levels and reversed insulin resistance (IR) in high fat-diet/streptozotocin-induced type 2 diabetes in rats. The expression levels of sterol receptor element-binding protein-1c (SREBP-1c) and carbohydrate-responsive element binding protein (ChREBP), which are involved in steatosis in NAFLD rats, were measured in the liver samples. MCE decreased the protein and mRNA expression levels of SREBP-1c and ChREBP. In conclusion, down-regulation of SREBP-1c and ChREBP might contribute to the protective effect of MCE on hepatic injury and IR in the rats with T2DM associated with NAFLD.

Diabetes is a widespread, rapidly increasing metabolic disease that is driven by hyperglycemia. Early glycemic control is of primary importance to avoid vascular complications including development of retinal disorders leading to blindness, end-stage renal disease, and accelerated atherosclerosis with a higher risk of myocardial infarction, stroke and limb amputations. Even after hyperglycemia has been brought under control, "metabolic memory," a cluster of irreversible metabolic changes that allow diabetes to progress, may persist depending on the duration of hyperglycemia. Manipulation of bile acid (BA) receptors and the BA pool have been shown to be useful in establishing glycemic control in diabetes due to their ability to regulate energy metabolism by binding and activating nuclear transcription factors such as farnesoid X receptor (FXR) in liver and intestine as well as the G-protein coupled receptor, TGR5, in enteroendocrine cells and pancreatic β-cells. The downstream targets of BA activated FXR, FGF15/21, are also important for glucose/insulin homeostasis. In this review we will discuss the effect of BAs on glucose and lipid metabolism and explore recent research on establishing glycemic control in diabetes through the manipulation of BAs and their receptors in the liver, intestine and pancreas, alteration of the enterohepatic circulation, bariatric surgery and alignment of circadian rhythms.

OBJECTIVETo evaluate the long-term clinical effect of Tangyiping Granules (, TYP) on patients with impaired glucose tolerance (IGT) to achieve normal glucose tolerance (NGT) and hence preventing them from conversion to diabetes mellitus (DM).

METHODSIn total, 127 participants with IGT were randomly assigned to the control (63 cases, 3 lost to follow-up) and treatment groups (64 cases, 4 lost to follow-up) according to the random number table. The control group received lifestyle intervention alone, while the patients in the treatment group took orally 10 g of TYP twice daily in addition to lifestyle intervention for 12 weeks. The rates of patients achieving NGT or experiencing conversion to DM as main outcome measure were observed at 3, 12, and 24 months after TYP treatment. The secondary outcome measures included fasting plasma glucose (FPG), 2-h postprandial plasma glucose (2hPG), glycosylated hemoglobin (HbA1c), fasting insulin (FINS), 2-h insulin (2hINS), homeostatic model assessment of insulin resistance (HOMA-IR), blood lipid and patients' complains of Chinese medicine (CM) symptoms before and after treatment.

RESULTSA higher proportion of the treatment group achieved NGT compared with the control group after 3-, 12- and 24-month follow-up (75.00% vs. 43.33%, 58.33% vs. 35.00%, 46.67% vs. 26.67%, respectively, P<0.05). The IGT to DM conversion rate of the treatment group was significantly lower than that of the control group at the end of 24-month follow-up (16.67% vs. 31.67%, P<0.05). Before treatment, FPG, 2hPG, HbA1c, FINS, 2hINS, HOMA-IR, triglyceride (TG), total cholesterol, low- and high-density lipoprotein cholesterol levels had no statistical difference between the two groups (P>0.05). After treatment, the 2hPG, HbA1c, HOMA-IR, and TG levels of the treatment group decreased significantly compared with those of the control group (P<0.05). CM symptoms such as exhaustion, irritability, chest tightness and breathless, spontaneous sweating, constipation, and dark thick and greasy tongue were significantly improved in the treatment group as compared with the control group (P<0.05). No severe adverse events occurred.

CONCLUSIONTYP administered at the IGT stage with a disciplined lifestyle delayed IGT developing into type 2 DM.

OBJECTIVETo evaluate the clinical efficacy and safety of Yinchen Zhufu Decoction (, YCZFD) in the treatment of acute-on-chronic liver failure caused by hepatitis B virus (HBV-ACLF) with cold pattern in Chinese medicine (CM).

METHODSThis is a multi-center randomized controlled trial of integrative treatment of CM and Western medicine (WM) for the management of HBV-ACLF patients. A total of 200 HBV-ACLF patients with cold pattern were equally randomly assigned to receive YCZFD and WM (integrative treatment) or WM conventional therapy alone respectively for 4 weeks. The primary end point was the mortality for HBV-ACLF patients. Secondary outcome measures included Model for End-Stage Liver disease (MELD) score, liver biochemical function, coagulation function and complications. Adverse events during treatment were reported.

RESULTSThe mortality was decreased 14.28% in the integrative treatment group compared with WM group (χ(2) =6.156, P=0.013). The integrative treatment was found to signifificantly improve the MELD score (t=2.353, P=0.020). There were statistically signifificant differences in aspartate transaminase, total bilirubin, indirect bilirubin, direct bilirubin and prothrombin time between the two groups (P<0.05 or P<0.01). The complications of ascites (χ(2)=9.033, P=0.003) and spontaneous bacteria peritonitis (χ(2)=4.194, P=0.041) were improved signifificantly in the integrative treatment group. No serious adverse event was reported.

CONCLUSIONSThe integrative treatment of CM and WM was effective and safe for HBV-ACLF patients with cold pattern in CM. The Chinese therapeutic principle "treating cold pattern with hot herbs" remains valuable to the clinical therapy. (Trial registration No. ChiCTR-TRC-10000766).

BACKGROUND/AIMS: Hepatic damage during transarterial chemoembolization (TACE) is a critical complication in patients with hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC). Apart from its role in preventing HBV reactivation, there is some evidence for the benefits of preemptive antiviral therapy in TACE. This study evaluated the effect of preemptive antiviral therapy on acute hepatic deterioration following TACE. METHODS: This retrospective observational study included a prospectively collected cohort of 108 patients with HBV-related HCC who underwent TACE between January 2007 and January 2013. Acute hepatic deterioration following TACE was evaluated. Treatment-related hepatic decompensation was defined as newly developed encephalopathy, ascites, variceal bleeding, elevation of the bilirubin level, prolongation of prothrombin time, or elevation of the Child-Pugh score by ≥2 within 2 weeks following TACE. Univariate and multivariate analyses were conducted to identify factors influencing treatment-related decompensation. Preemptive antiviral therapy involves directing prophylaxis only toward high-risk chronic hepatitis B patients in an attempt to prevent the progression of liver disease. We regarded at least 6 months as a significant duration of preemptive antiviral treatment before diagnosis of HCC. RESULTS: Of the 108 patients, 30 (27.8%) patients received preemptive antiviral therapy. Treatment-related decompensation was observed in 25 (23.1%) patients during the follow-up period. Treatment-related decompensation following TACE was observed more frequently in the nonpreemptive group than in the preemptive group (29.5% vs. 6.7%, P=0.008). In the multivariate analysis, higher serum total bilirubin (Hazard ratio [HR] =3.425, P=0.013), hypoalbuminemia (HR=3.990, P=0.015), and absence of antiviral therapy (HR=7.597, P=0.006) were significantly associated with treatment-related hepatic decompensation. CONCLUSIONS: Our findings suggest that preemptive antiviral therapy significantly reduces the risk of acute hepatic deterioration. Preventing hepatic deterioration during TACE by applying such a preemptive approach may facilitate the continuation of anticancer therapy and thus improve long-term outcomes.
