OBJECTIVETo evaluate the quality and consistency of recommendations in the clinical practice guidelines (CPGs) for hypertension in Chinese medicine (CM).

METHODSCM CPGs were identified from 5 electronic databases and hand searches through related handbooks published from January 1990 to December 2013. Three reviewers independently appraised the CPGs based on the Appraisal of Guidelines for Research and Evaluation (AGREE II) instrument, and compared the CPGs' recommendations on CM syndrome pattern classification and treatment.

RESULTSFive CM CPGs for hypertension were included. The quality score of the evidence-based (EB) guideline was higher than those of the consensus-based with no explicit consideration of evidence-based (CB-EB) and the consensus-based (CB) guidelines. Three out of five patterns in the CPGs were recommended by the EB guideline. Tianma Gouteng Formula () in the EB guideline was recommended mostly for hypertension patients with pattern of ascendant hyperactivity of Gan (Liver)-yang and pattern of yin deficiency with yang hyperactivity in the CPGs. Acupuncture and massage were recommended for Grade I and Grade II hypertension with severe symptoms weakening the quality of life in the EB guideline. For Grade I and Grade II hypertension, CM could be used alone, while for Grade III hypertension, they should be used in combination with Western medicines.

CONCLUSIONThe quality of EB guideline was higher than those of CB and CB-EB CPGs in CM for hypertension and CM should be prescribed alone or combined with Western medicines based on the grade of hypertension.

Objective To study the existence and significance of cholesterol-intestinal hepatic circulation in rabbits by establishing a model of enterohepatic circulation and blocking enterohepatic circulation. Methods In this experiment, the experimental group and the control group were set up to conduct high-cholesterol diets and ordinary diets for differential feeding. By establishing a model of enterohepatic circulation and blocking enterohepatic circulation, cholesterol oxidase method was used to measure serum cholesterol concentration in the experimental group and the control group respectively. Based on the statistical analysis of the data for 6 months, the phenomenon of enterohepatic circulation of cholesterol was studied. Results Based on the data of 6 months, the serum cholesterol concentrations of rabbits in groups Aand Cwere gradually increased. After two months, the hypercholesterolemia was significant in the rabbits in group C. The increase degree of serum cholesterol concentration in the rabbits in group Awas weaker than that in group C. Hypercholesterolemia had no obvious effect. There was statistically significant difference between group Aand group C (P＜0. 05); serum cholesterol concentration in rabbits in group Dwas increased slightly, but the increase was not significant. The increase of serum cholesterol concentration in group Bwas more significant than that of group D. There was a statistically significant difference between group Band group D (P＜0. 05). The serum TC-time line graph was plotted with the serum cholesterol concentration in each group as the ordinate and the time as the abscissa. Compared with group A, the serum cholesterol was increased significantly in group C. Compared with group D, the serum cholesterol in group Bwas increased significantly. Conclusion This experiment shows that the cholesterol enterohepatic circulation phenomenon exists in rabbits. By blocking the enterohepatic circulation in rabbits, it has a certain effect on lowering the content of serum cholesterol in rabbits. This will provide a theoretical basis for further studying the role of blocking enterohepatic circulation in reducing cholesterol levels in the body. It provides new ideas for the clinical treatment of hypercholesterolemia by blocking the cholesterol enterohepatic circulation in clinical practice and points a direction for drug development.

BACKGROUNDDespite a recent American Heart Association (AHA) consensus statement emphasizing the importance of resistant hypertension (RH), its control is still a challenge for conventional medicine. The Chinese herbal formula, Qutan Huayu Fang, has been used effectively to assist antihypertensive agents in blood pressure control, but its effect for RH patients is still unclear. This pilot study aims to explore the effects of taking the formula in addition to antihypertensive medication in the management of RH.

METHODS/DESIGNA prospective cohort study will be conducted in two first-class hospitals of traditional Chinese medicine (TCM). Eligible RH patients will be classified as the experimental group (n = 100) and the control group (n = 100) based on the interventions they receive. Participants taking antihypertensive agents and the Chinese herbal formula will be in the experimental group and those taking antihypertensive agents alone will be in the control group. The whole study will last 24 weeks, including an 8-week observation and follow-up at 24 weeks. The primary outcomes, assessed against patient baseline conditions, will be the reduction of systolic blood pressure and diastolic blood pressure as well as changes in TCM symptoms and signs. These outcomes will be assessed at weeks 2, 4, 6, and 8. The reductions of blood pressure will also be assessed at week 24. Cardiac events and mortality rate will be secondary outcomes and will be assessed at weeks 8 and 24. Any adverse reactions will be recorded during the study. The causal inference method will be used to assess the effectiveness of the inclusion of TCM herbal medicine in the management of patients with RH.

DISCUSSIONThis study will determine whether the Chinese herbal formula is helpful for RH patients treated with antihypertensive agents and the findings will provide a basis for further confirmatory studies.

OBJECTIVETo systematically review the clinical practice guidelines (CPGs) for ischemic stroke in Chinese medicine (CM) with the Appraisal of Guidelines for Research and Evaluation (AGREE II) instrument.

METHODSCM CPGs for ischemic stroke were searched in 5 online databases and hand-searches in CPGrelated handbooks published from January 1990 to December 2012. The CPGs were categorized into evidence based (EB) guideline, consensus based with no explicit consideration of evidence based (CB-EB) guideline and consensus based (CB) guideline according to the development method. Three reviewers independently appraised the CPGs based on AGREE II instrument, and compared the CPGs' recommendations on CM pattern classification and treatment.

RESULTSFive CM CPGs for ischemic stroke were identified and included. Among them, one CPG was EB guideline, two were CB guidelines and two were CB-EB guidelines. The quality score of the EB guideline was higher than those of the CB-EB and CB guidelines. Five CM patterns in the CPGs were recommended in the EB CPG. The comprehensive protocol of integrative Chinese and Western medicine recommended in the EB CPG was mostly recommended for ischemic stroke in the CPGs. The recommendations varied based on the CM patterns.

CONCLUSIONThe quality of EB CPG was higher than those of CB and CB-EB CPGs in CM for ischemic stroke and integrative approaches were included in CPGs as major interventions.

OBJECTIVETo investigate the apoptosis of bladder cancer cell 5637 induced by pseudolaric acid B in vitro and its mechanism.

METHODThe cell proliferation was detected by MTT assay;the cell cycle was measured by flow cytometry; the cell apoptosis was observed by flow cytometry with Annexin V-FITC/PI double staining; the expressions of survivin protein and caspase-3 protein were detected by Western blot assay.

RESULTIt showed that pseudolaric acid B remarkably induced apoptosis of 5637 cell line. Moreover, pseudolaric acid B suppressed survivin and up-regulated caspase-3 expression.

CONCLUSIONPseudolaric acid B inhibits the proliferation and induces the apoptosis of 5637 cells. The molecular mechanism of pseudolaric acid B inducing the apoptosis of 5637 cells may be associated with its action of down-regulating the expression of survivin, and up-regulating the expression of caspase-3.

BACKGROUND:Recent investigations show that there are a small part of self-renewing and multi-potent cells named as tumor stem cells.Those cells share many characteristics with somatic and embryonic stem cells and are thought to be responsible for driving tumor progression in growing list of neoplastic diseases.Vascular endothelial growth factor(VEGF)is an important angiogenesis factor,which can regulate endothelial proliferation,angiogenesis,permeability of blood vessel,and thrombogenesis.OBJECTIVE:To summarize the progress of cancer stem cells and tumor angiogenesis.METHODS:A computer-based online search was conducted in PUMMED,CNKI,and Wanfang databases with the key words of "cancer stem cells,vascular endothelial growth factor,new vascularize" in both Chinese and English from January 2000 to October 2009.RESULTS AND CONCLUSION:Among 153 articles,there were 13 in Chinese and 140 in English.Titles and abstracts were preliminarily screened,and articles which were non-relative(n=35),duplicated(n=30),and Meta analysis(n=57),were excluded.A total of 31 articles were included in the final analysis.Angiogenesis regulated by multiple factors was a necessary link for tumor growth and transferring.Stem cells promoted angiogenesis,thereby promoted tumor growth and transferring.However,the modified stem cells caused the opposite effects.On the other hand,the stem cells were considered as a substance vector to localize tumor focus,in particular,it will be potential for looking for subclinical focus and distal focus.

Objective To observe the effects of arsenic trioxide (As2O3) on T24 bladder cancer cells growth, Caspase-3 gene expression, as well as the weight and volume changes of transplantation tumor of hairless mouse. Methods The cell proliferation inhibition was measured by MTT colorimetric assay. Morphological changes in the cell nucleus was measured by fluorescein stain. Morphologic cell apoptosis was analyzed by FCM. The espression of Caspase-3 was observed by immunocytochemistry staining. The weight and volume changes of transplantation tumor of hairless mouse were measured before and after As2 O3 was used. Results As2 O3 could significantly inhibit the growth of T24 cells, which depended on the reaction time and concentration of drug. With the extension of the time, the increase in the rate of apoptosis and expression of casepase-3 increased. The tumor size and tumor analysis of As2O3 group decreased than those of the control group(P＜0. 05). Conclusion As2O3 could significantly inhibit the growth of bladder cancer cells and its anti-cancer mechanisms may be related to increased Caspase-3 protein expression.
