[Trametenolic acid inhibits migration and invasion of hepatocellular carcinoma HepG2.2.15 cells via RhoC/ROCK1 pathway].

This study investigated the effect of trametenolic acid(TA) on the migration and invasion of human hepatocellular carcinoma HepG2.2.15 cells by using Ras homolog gene family member C(RhoC) as the target and probed into the mechanism, aiming to provide a basis for the utilization of TA. The methyl thiazolyl tetrazolium(MTT) assay was employed to examine the proliferation of HepG2.2.15 cells exposed to TA, and scratch and Transwell assays to examine the cell migration and invasion. The pull down assay was employed to determine the impact of TA on RhoC GTPase activity. Western blot was employed to measure the effect of TA on the transport of RhoC from cytoplasm to cell membrane and the expression of RhoC/Rho-associated kinase 1(ROCK1)/myosin light chain(MLC)/matrix metalloprotease 2(MMP2)/MMP9 pathway-related proteins. RhoC was over-expressed by transient transfection of pcDNA3.1-RhoC. The changes of F-actin in the cytoskeleton were detected by Laser confocal microscopy. In addition, the changes of cell migration and invasion, expression of proteins in the RhoC/ROCK1/MLC/MMP2/MMP9 pathway, and RhoC GTPase activity were detected. The subcutaneously transplanted tumor model of BALB/c nude mice and the low-, medium-, and high-dose(40, 80, and 120 mg·kg~(-1), respectively) TA groups were established and sorafenib(20 mg·kg~(-1)) was used as the positive control. The tumor volume and weight in each group were measured, and the expression of related proteins in the tumor tissue was determined by Western blot. The results showed that TA inhibited the proliferation of HepG2.2.15 cells in a concentration-dependent manner, with the IC_(50) of 66.65 and 23.09 µmol·L~(-1) at the time points of 24 and 48 h, respectively. The drug administration groups had small tumors with low mass. The tumor inhibition rates of sorafenib and low-, medium-and high-dose TA were 62.23%, 26.48%, 55.45%, and 62.36%, respectively. TA reduced migrating and invading cells and inhibited RhoC protein expression and RhoC GTPase activity in a concentration-dependent manner, dramatically reducing RhoC and membrane-bound RhoC GTPase. The expression of ROCK1, MLC, p-MLC, MMP2, and MMP9 downstream of RhoC can be significantly inhibited by TA, as confirmed in both in vitro and in vivo experiments. After HepG2.2.15 cells were transfected with pcDNA3.1-RhoC to overexpress RhoC, TA down-regulated the protein levels of RhoC, ROCK1, MLC, p-MLC, MMP2, and MMP9 and decreased the activity of RhoC GTPase, with the inhibition level comparable to that before overexpression. In summary, TA can inhibit the migration and invasion of HepG2.2.15 cells. It can inhibit the RhoC/ROCK1/MLC/MMP2/MMP9 signaling pathway by suppressing RhoC GTPase activity and down-regulating RhoC expression. This study provides a new idea for the development of autophagy modulators targeting HSP90α to block the proliferation and inhibit the invasion and migration of hepatocellular carcinoma cells via multiple targets of active components in traditional Chinese medicines.

Overview on Animal Models of Throat Impediment / 中国实验方剂学杂志

Objective: To summarize and evaluate the existing animal models of pharyngitis, in order to provide a theoretical basis for its treatment and research of traditional Chinese medicine (TCM) for throat impediment. Method: Nearly 5 years of literatures were retrieved form databases of Chinese national knowledge infrastructure (CNKI), SinoMed and Pubmed, with throat impediment, pharyngitis, and animal model as medicine subject headings terms. Result: At present, rats, rabbits, guinea pigs and macaques are available as model animals. The main methods for reproduction of pharyngitis animal model were direct ammonia molding, ammonia and turpentine combined molding and bacterial injection molding. The rarely used methods, such as pyridine induction method, capsaicin induction method and sand dust induction method, have their own characteristics. The pharyngitis animal models with the combination of TCM syndrome include YIN-deficiency type and stagnation of liver-Qi with deficiency of spleen type. These models evaluation indexes were diverse, including apparent behavior, histopathology, biochemical indicator and hemorheology. The problems of these modeling methods included the differences in etiology and mechanism between the methods of modeling and the formation of clinical patients, the lack of molecular level of pathological mechanism elaboration, the non-uniform standard for concentration, frequency and cycle of drug administration during modeling, the subjectivity in judging partial evaluation indexes and the deficiency of the pharyngitis animal model with the combination of TCM syndrome. Conclusion: Firstly, the existing models needed to be further improved by such means as the exploration of the correlation or consistency between the molecular pathology mechanism and the clinical pathogenesis, and the concentration and frequency of uniform model administration and uniform standard for evaluation indexes. Secondly, the pharyngitis animal model with the combination of TCM syndrome and modern medicine disease was urgently needed to be explored, in order to facilitate the development of basic research in TCM.

Toxicity of mineral Chinese medicines containing mercury element / 中国中药杂志

Mineral Chinese medicine is the distinctive part of the Chinese traditional medicine. The mineral Chinese medicines containing mercury elements such as cinnabaris, calomelas and hydrargyri oxydum rubrum are widely applied in the clinical conditions because of their efficacy of sedative, sterilization, removing necrotic tissue and promoting granulation. However, the rationality and security of clinical application are questioned because of the toxic effect caused by mercury compounds. This paper would summarize the efficacy of the mineral Chinese medicines containing mercury element, as well as their hepatotoxicity, nephrotoxicity, embryotoxicity, and neurotoxicity effect and mechanisms. Improper usage or high dose of the mineral Chinese medicines containing mercury element would cause acute hepatotoxicity. Cinnabaris, calomelas and hydrargyri oxydum rubrum may lead to chronic hepatotoxicity, nephrotoxicity, embryotoxicity and neurotoxicity when they were applied externally to the skin for long-term use. In addition to the accumulation of mercury elements in the tissues and organs, the species and forms of mercury compounds absorbed into the body in different ways, should be also studied in order to understand the toxicity of the mineral Chinese medicines containing mercury element. Meanwhile the dose and period of treatment shall be also considered in order to provide the references for rational and safe clinical application of the mineral Chinese medicines containing mercury element.

The mediating effect of self-efficacy on mindfulness and job burnout in psychological counselors / 中华行为医学与脑科学杂志

Objective To explore the mediating role of self-efficiency between mindfulness and job burnout in psychological counselors. Methods 201 psychological counselors were tested by the demograph-ic data Questionnaire,Maslach Burnout Inventory(MBI-GS),General Self-Efficacy Scale(GSES),Mindful-ness attention and mindfulness scale(MAAS). The structural equation model was used to explore the media-ting role of self-efficacy in the relationship between mindfulness and job burnout. Results Mindfulness in psychological counselors was negatively correlated with emotional exhaustion and depersonalization(r=-0.50,-0.43;P<0.01),while there was a significant positive correlation with personal accomplishment(r=0.30,P<0.01). Self-efficiency was negatively correlated with emotional exhaustion and depersonalization(r=-0.30,-0.32;P<0.01),while there was a significant positive correlation with personal accomplishment(r=0.40,P<0.01). Mindfulness was positively correlated with self-efficiency(r=0.31,P<0.01). The mediating effect showed that self-efficacy played a partial mediating effect on the relationship between mindfulness and job burnout(effect value:-0.071,95%CI= -0.027--0.141),and the mediation effect accounted for 14.82%of the total effect. Conclusion Self-efficiency plays a partial mediating role between job burnout and mind-fulness in psychological counselors. Improving the level of mindfulness and self-efficiency have positive effect on job burnout of the psychological counselors.

Effect of protein intervention on amino acid metabolism spectrum of Qi and Yin deficiency type 2 diabetic rats / 中国中药杂志

To study the effect of plant protein and animal protein on amino acid metabolism spectrum of Qi and Yin deficiency type 2 diabetic rats. 110 male SD rats were randomly divided into blank group (n=10), diabetic model group (n=20), disease-symptoms group (n=80). The rats of blank group received ordinary feeding, while other groups were fed with high sugar and fat diets. During the whole process of feeding, rats of disease-symptoms group were given with Qingpi-Fuzi (15.75 g•kg⁻¹) once a day through oral administration. Five weeks later, the rats were given with a low dose of STZ (40 mg•kg⁻¹) by intraperitoneal injection to establish experimental diabetic models. Then the models were randomly divided into disease-symptoms group 1 (Qi and Yin deficiency diabetic group, 15.75 g•kg⁻¹), disease-symptoms group 2 (plant protein group, 0.5 g•kg⁻¹), disease-symptoms group 3 (animal protein group, 0.5 g•kg⁻¹), disease-symptoms group 4 (berberine group, 0.1 g•kg⁻¹). The drugs were given for 4 weeks by gavage administration. After 4 weeks of protein intervention, the abdominal aortic blood was collected and serum was isolated to analyze its free amino acid by using AQC pre-column derivatization HPLC and fluorescence detector. Four weeks after the protein intervention, plant protein, animal protein and berberine had no obvious effect on body weight and blood sugar in type 2 diabetic rats. As compared with animal protein group, histidine and proline（P<0.01）, serine, glycine, threonine, alanine, tyrosine, valine, methionine, bright+isoleucine, phenylalanine and lysine（P<0.05）changed a lot in rats serum of plant protein group.The results showed that gavage administration of protein would produce effects on amino acid metabolism of Qi and Yin deficiency type 2 diabetic SD rats. Symbolic differential compounds could be found through metabonomics technology, providing experimental basis for early warning of type 2 diabetes and diagnosis of Qi and Yin deficiency syndrome.

Bioassay for enrich-blood bioactivity of Agelicae Sinensis Radix / 中国中药杂志

Danggui, Agelicae Sinensis Radix, is a widely used Chinese herb to enrich blood, but its quality cannot be effectively assessed by the known chemical markers such as ferulic acid, ligustilide, polysaccharides, etc. A new bioassay was therefore developed to quantify the Enrich-Blood Bioactivity (EBB) for the quality assessment of Danggui raw materials. Danggui sample was first extracted with ethanol and water, respectively. Then the ethanolic extract and water extract were mixed as a test sample to quantify the amount of EBB by mice experiment. The blood deficiency mode in mice was developed by intraperitoneal injecting cyclophospharmide and phenylhdrazine hydrochloride. The quantity of red blood cell was chosen as EBB marker. Cyclosporine A was chosen as a control substance. EBB in analytes was quantified by the amount reaction of parallel line analysis (3, 3') method. The results indicated that the reliability test for quantifying EBB was passed through and the measured value was valid. The analytes showed the significant EBB (P < 0.05). The correlation coefficient was 0.9984 (n=5) between the amount of cyclosporine A (0.035-0.56 g x kg(-1)) and the increased number of red blood cell. The relative standard deviation (RSY) on the amount of EBB was estimated to be 6.15% (n = 6) by six replicated tests, and the confidence limit rate was 26.68% (n = 6). Five Danggui samples, which were collected from different cultivation areas with various morphological characters, showed the variety of EBB in the range of 21.95-44.16 U x g(-1). It is concluded that the developed method is accurate to quantify the EBB of Danggui raw materials, and is therefore suitable to assess its quality.

Effect of piperine on 5-HT and synaptophysin expression of rats with irritable bowel syndrome / 药学学报

This study is to explore the amelioration of piperine on chronic acute combining stress rat with depression-like behavior, visceral sensitivity, and its effect on the expression of serotonin (5-HT) and synaptophysin. Forty two SD rats were divided into seven groups: blank group, model group, piperine (12.5, 25, 50 and 100 mgkg-1, ig) and imipramine (10 mgkg-1, ip) groups. The rat model of irritable bowel syndrome was established by chronic acute combining stress, and then to evaluate depression-like behavior and visceral sensitivity. The expressions of 5-HT and synaptophysin in the hippocampus and colon were determined by high performance liquid chromatography (HPLC) and Western blotting, respectively. The duration of immobility of IBS rat in the forced swimming test had been significantly increased, the sucrose consumption of IBS rat had been reduced and visceral sensitivity was obviously elevated in the IBS model group as compared with those in the normal control group (P<0.05, P<0.01). As compared with those in the normal control group, the expression of 5-HT significantly decreased, 5-HIAA/5-HT ratio significantly increased in the hippocampus of IBS model group (P<0.05), but opposite presentations were noted in the colon (P<0.05). As compared with that in the normal control group, the synaptophysin expression in the hippocampus decreased significantly but obviously increased in the colon (P<0.05). Piperine improved the behavior of IBS rats, and reversed the levels of 5-HT and 5-HIAA, and 5-HIAA/5-HT proportion in the hippocampus and colon (P<0.05); besides, they significantly reverse the synaptophysin level in the hippocampus and colon (P<0.05). The presence of depression and visceral sensitivity had been changed in IBS rats, with abnormal expression of 5-HT and synaptophysin in the brain-gut system. Piperine can ameliorate the changes of the behavior and regulation of serotonin and synaptophysin expression in IBS rat model.

Meanwhile, acupuncture was added to the medication--acupuncture group at bilateral Neiguan (PC 6), Shenmen (HT 7), Ximen (PC 4) with uneven reinforcing-reducing manipulation every 15 min, 1 min each time. The needle was retained for 30 minutes. The acupuncture was given once daily for continuously 4 weeks. The therapeutic efficacy of the two groups was assessed after treatment.</p><p><b>METHODS</b>In the medication+acupuncture group, 18 cases were markedly effective, 10 cases were effective and 2 cases were failed, the total effective rate was 93.3%; in the medication group, 15 cases were markedly effective, 8 cases were effective and 7 cases were failed, the total effective rate was 76.7%. There were statistical significances in clinical efficacy between the two groups (P<0.05).</p><p><b>CONCLUSION</b>Acupuncture combined with Wenxin granule has a better effect than simple Wenxin granule therapy in the treatment of paroxysmal atrial fibrillation.</p>

Analgesic effect of CQM on prosopalgia model rats and its impact on exciting amino acid neurotransmitters / 中国中药杂志

<p><b>OBJECTIVE</b>To observe the analgesic effect of CQM on photochemically-induced prosopalgia model rats, and discuss its impact on the exciting amino acid neurotransmitter-glutamate (Glu).</p><p><b>METHOD</b>Male SD rats were randomly divided into the sham operation group and the prosopalgia group. And the latter was subdivided into the model group, the gabapentin group (100 mg kg(-1)), and the CQM low-dose (35 mg x kg(-1)) and CQM high-dose (70 mg x kg(-1)) groups. The mechanical allodynia test was adopted to evaluate the pain behavior of rats, and reflect the efficacy with the mechanical withdrawal thresholds. The rat striatum extra-cellular fluid was collected by brain micro-dialysis. The Glu level of samples was measured by high performance liquid chromatography-fluorescene detector (HPLC-FLD).</p><p><b>RESULT</b>Compared to the control group, the threshold of the mechanical allodynia of the IoN injury group was decreased significantly (P < 0.05), and the concentration of Glu was increased dramatically (P < 0.05). Compared to the model group, the mechanical allodynia of photochemically-induced prosopalgia model rats increased significantly (P < 0.01), with a notable increase in brain Glu concentration (P < 0.05). Compared with the model group, all of mechanical withdrawal thresholds increased. Among them, the CQM high-dose group showed a remarkably growth at three time points (P < 0.05), with the maximum up to (23 +/- 7.3) g. And the gabapentin group showed a remarkably growth at two time points (P < 0.05), with the maximum up to (20.5 +/- 9.2) g. All of the drug groups showed significantly lower Glu concentrations in rat brains than the model group (P < 0.05).</p><p><b>CONCLUSION</b>CQM can ease the mechanical allodynia of photochemically-induced prosopalgia model rats. Its analgesic effect may be related to the decrease of Glu concentrations in striatum extra-cellular fluid.</p>

Study on intervention effect of Danggui Shaoyao San on rats with cirrhotic ascites / 中国中药杂志

<p><b>OBJECTIVE</b>To investigate the intervention effect of Danggui Shaoyao San on rats with cirrhotic ascites, and discuss the effect of arginine vasopressin (AVP) on cirrhotic ascites.</p><p><b>METHOD</b>Male SD rats were randomly divided into the control group, the model group, Danggui Shaoyao San low, middle and high dose groups. The cirrhotic ascites rat model was established by CCl4 combined with phenobarbital. Their urines were collected at 24 h to observe urine excretion of each group. Filter papers were used to determine the amount of ascites. The levels of serum alanine aminotransferasa (ALT) , aspartate aminotransferase (AST) were detected by the automatic biochemistry analyzer. Plasma prothrombin time (PT) was evaluated by the blood coagulation analyzer. The concentration of AVP in plasma was detected by enzyme-linked immunosorbent assay (ELISA). Pathological changes in livers were observed by HE staining.</p><p><b>RESULT</b>Compared with the model group, the Danggui Shaoyao San group showed significant improvement in live indexes, with notable decrease in serum ALT and AST and the time of PT, improvement in liver pathological changes. Simultaneously, the amount of ascites decreased to varying degrees, with notable increase in urine in 24 h and decrease in AVP concentration in plasma.</p><p><b>CONCLUSION</b>Danggui Shaoyao San can notably improve liver functions of rats with cirrhotic ascites, reduce the generation of ascites and delay the progress of liver pathological changes. Its mechanism may be related to AVP.</p>
