ABSTRACT
Esophageal cancer is an upper gastrointestinal malignancy with a bleak prognosis.It is still being explored in depth due to its complex molecular mechanisms of occurrence and development.Lipids play a crucial role in cells by participating in energy supply,biofilm formation,and signal transduction pro-cesses,and lipid metabolic reprogramming also constitutes a significant characteristic of malignant tu-mors.More and more studies have found esophageal cancer has obvious lipid metabolism abnormalities throughout its beginning,progress,and treatment resistance.The inhibition of tumor growth and the enhancement of antitumor therapy efficacy can be achieved through the regulation of lipid metabolism.Therefore,we reviewed and analyzed the research results and latest findings for lipid metabolism and associated analysis techniques in esophageal cancer,and comprehensively proved the value of lipid metabolic reprogramming in the evolution and treatment resistance of esophageal cancer,as well as its significance in exploring potential therapeutic targets and biomarkers.
ABSTRACT
Ardisia Crenata Radix is a traditional Chinese medicinal plant that belongs to the Myrsinaceae family,and its main active components are coumarins,saponins,flavonoids,and volatile oil.Bergenin,ardisicrenoside A,ardisicrenoside B,ardisiacripin A,ardisiacripin B,and embelin were identified as active anticancer compounds in in-depth studies into the anti-tumor effects of Ardisia Crenata Radix.They show high therapeutic potential in oral cancer,nasopharyngeal carcinoma,liver cancer,colon cancer,bladder cancer,cervical cancer,and leukemia,mainly by inducing tumor cell apoptosis,increasing tumor cytotoxicity,inhibiting cell proliferation,inhibiting tumor cell metastasis and migration,and inducing cell regulatory enzyme cascade reactions.However,most preclinical experimental data on cinnabar root's anti-tumor mechanism have not been verified in high-quality,multi-sample,and repeated randomized controlled trials,and there are a lack of clinical research data on tumor prognosis,pharmacodynamics,and pharmacokinetics.Accurate research experiments and clinical trials should be designed to further explore the pharmacological effects of Ardisia Crenata Radix.
ABSTRACT
Delayed diabetic wound healing has placed an enormous burden on society. The key factors limiting wound healing include unresolved inflammation and impaired angiogenesis. Platelet-rich plasma (PRP) gel, a popular biomaterial in the field of regeneration, has limited applications due to its non-injectable properties and rapid release and degradation of growth factors. Here, we prepared an injectable hydrogel (DPLG) based on PRP and laponite by a simple one-step mixing method. Taking advantages of the non-covalent interactions, DPLG could overcome the limitations of PRP gels, which is injectable to fill irregular injures and could serve as a local drug reservoir to achieve the sustained release of growth factors in PRP and deferoxamine (an angiogenesis promoter). DPLG has an excellent ability in accelerating wound healing by promoting macrophage polarization and angiogenesis in a full-thickness skin defect model in type I diabetic rats and normal rats. Taken together, this study may provide the ingenious and simple bioactive wound dressing with a superior ability to promote wound healing.

ABSTRACT
The amorphous solid dispersion is one of the most effective formulation approaches to enhance the oral bioavailability of poorly water-soluble drugs. However, the amorphous drugs tend to crystallize during storage or dissolution due to inadequate formulations, preparation techniques, storage and dissolution conditions, thus negating their advantages. Meanwhile, it is often difficult to establish in vitro-in vivo correlation for amorphous solid dispersions owing to the difference between dissolution media and physiological environments and between the apparent concentration and membrane transport flux, the dynamic process of the in vivo absorption, which put great challenges to the development of amorphous solid dispersion products. This review covers the recent progress on the mechanistic study of the in vitro dissolution and in vivo absorption of amorphous solid dispersions, aiming to provide guidance for the formulation development of poorly soluble drugs.
ABSTRACT
Objective:To analyze the value of minute ventilation to carbon dioxide production slope (VE/VCO 2 slope) combined with peak systolic blood pressure (SBP) in predicting prognosis for patients with chronic heart failure (CHF). Methods:A total of 170 patients with CHF who visited the Cardiac Rehabilitation Center of Tongji Hospital Affiliated to Tongji University and completed cardiopulmonary exercise test from March 2007 to December 2018 were enrolled in the study. The clinical data, cardiopulmonary exercise testing results and follow-up information of patients were collected to explore the predictors of all-cause mortality in patients with CHF.Results:The median follow-up time was 647 (182-1 764) days. All-cause death occurred in 34 patients. Compared with surviving patients, the proportion of diabetes and angiotensin-converting enzyme inhibitor/angiotensin Ⅱ receptor blocker (ACEI/ARB) use in fatal patients was significantly higher ( P<0.01). The VE/VCO 2 slope and peak SBP*VE/VCO 2 in the fatal patients were significantly higher, and the peak oxygen consumption (peak VO 2) was lower than those in the surviving patients ( P<0.01). The areas under the receiver operating characteristic curve (AUC) of VE/VCO 2 slope and peak SBP*VE/VCO 2 in predicting all-cause mortality in patients with CHF were 0.648 ( P=0.008) and 0.681 ( P=0.001), respectively; the optimal thresholds were >40.95 ( P=0.008) and > 5 423.50 mmHg (1 mmHg=0.133 kPa, P=0.006), the sensitivity was 0.559 and 0.588, and the specificity was 0.728 and 0.735, respectively. Multivariate Cox regression analysis showed that after adjusting for age, gender, diabetes and ACEI/ARB use, VE/VCO 2 slope ( HR=2.12, P=0.036) and peak SBP*VE/VCO 2 ( HR=2.42, P=0.016) were independent risk factors for all-cause mortality in patients with CHF. Conclusion:Compared to the traditional index VE/VCO 2 slope, a novel index peak SBP* VE/VCO 2 provides a relatively better predictive value for all-cause death of CHF patients.
ABSTRACT
OBJECTIVE:To study the improvement effects of Weijing deco ction on AECOPD model rats and its possibile mechanism.

Except for normal group ,AECOPD model was induced by cigarettes combined with lipopolysaccharide in other groups. After modeling ,normal group and model group were given constant volume of water intragastrically ,and other groups were given relevant medicine intragastrocally ,twice a day ,for 14 days. After last intragastric administration ,the serum level of IL- 1 β was determined,and pathological changes of lung tissue and bronchus were observed in each group ;mRNA expression of MMP-9 and TIMP- 1 genes in lung tissue were detected ;protein expression of Ras homologous gene family member (RhoA), dishevelled associated activator of morphogenesis- 1(DAAM1)and hyperplasic suppress gene (HSG)in lung tissue were also determined. RESULTS :Compared with normal group ,the levels of IL- 1β in serum,mRNA expression of MMP- 9 and TIMP-1 as well as protein expression of RhoA and DAAM 1 in lung tissue were increased significantly in the model group(P<0.05),while protein expression of HSG in lung tissue was decreased significantly (P<0.05);there were many chronic inflammatory cells infiltrating around the bronchus ,some airway mucosa epithelium exfoliating ,alveolar compensatory dilation,pulmonary septal capillary dilation and hyperemia. Compared with model group ,the levels of IL- 1β in serum,mRNA expression of MMP- 9 and TIMP- 1 in lung tissue were decreased significantly in Weijing decoction high-dose group (P<0.05);the protein expression of RhoA and DAAM 1 in lung tissue were decreased significantly in Weijing decoction low-dose and high-dose groups(P<0.05),while the protein expression of HSG in lung tissue was increased (P<0.05);the pathological changes of Weijing decoction high-dose group ,such as inflammatory cells infiltrating around the bronchus and shedding of airway mucosa , were improved significantly , and there was complete alveolar epithelium structure but no obvious pulmonary dilation. CONCLUSIONS:Weijing decoction can improve AECOPD model rats to certain extent ;its mechanism may be associated with down-regulating mRNA expression of MMP- 9 and TIMP -1 as well as protein expression of RhoA and DAAM 1 in lung tissue , up-regulating protein expression of HSG in lung tissue so as to inhibit the airway remodeling.
ABSTRACT
Objective: To observe the effect of mild moxibustion on cancer-related fatigue, serum ghrelin and adiponectin in patients undergoing chemotherapy after colorectal cancer surgery. Methods: Seventy patients were divided into a control group and an observation group according to the random number table method, with 35 cases in each group. Patients in both groups were treated with conventional FOLFOX4 chemotherapy regimen. Patients in the control group also received routine treatments such as symptomatic treatment of complications, health education, nutritional support, and exercise intervention. Patients in the observation group received mild moxibustion on the basis of interventions used in the control group. The Piper fatigue scale-revision (PFS-R), Karnofsky performance status (KPS) and spleen and kidney yang deficiency syndrome were scored, and serum ghrelin and adiponectin levels were measured before and after treatment. Results: After treatment, total score of PFS-R in the control group did not change significantly (P>0.05), while in the observation group it was significantly reduced (P<0.05) and lower than that in the control group (P<0.05); KPS scores in both groups were increased (both P<0.05), and it was significantly higher in the observation group than in the control group (P<0.05); total score of spleen and kidney yang deficiency syndrome in the control group did not change significantly (P>0.05), while it was significantly reduced in the observation group (P<0.05) and lower than that in the control group (P<0.05); serum ghrelin and adiponectin levels in the control group had no significant changes (both P>0.05), but the levels were significantly increased in the observation group (both P<0.05) and higher than those in the control group (both P<0.05). Conclusion: Based on the routine treatments, mild moxibustion can relieve fatigue, improve quality of life, and improve the symptoms of spleen and kidney yang deficiency in patients undergoing chemotherapy after colorectal cancer surgery, which may be related to the regulation of serum ghrelin and adiponectin levels.
ABSTRACT
Chronic hepatitis B virus (HBV) infection is a serious health issue because of its severe sequelae. Prevention of mother-to-child transmission (MTCT) of HBV is critical to eliminate chronic HBV infection. Here, we reviewed the progress toward the elimination of HBV infection in children in China in the recent decade. A universal hepatitis B vaccination program started from 2002 has been intensified, with the coverage of timely birth dose >95% of all newborn infants from 2012. Since 2011, China has taken a nationwide program to administer hepatitis B immunoglobulin (HBIG) with free of charge in all neonates of HBV-infected mothers, leading to a significant increment of timely use of HBIG. The prevalence of hepatitis B surface antigen (HBsAg) was declined from around 10% among children in 1980s to 2 × 105 U/mL during the third trimester is increasing, which will further reduce MTCT of HBV. However, there are some challenges in the elimination of HBV infection in children, which need to overcome by the concerted efforts. Nevertheless, it is anticipated that China will achieve the goal set by the World Health Organization that the prevalence of HBsAg in children aged <5 years is ≤0.1% by 2030.

Objective:To detect whether Toll-like receptor 4 ( TLR4) polymorphisms contributed to primary open angle glaucoma (POAG) in a Chinese population. Methods:A Chinese cohort, including 799 unrelated POAG patients and 799 unrelated controls, was enrolled in our case-control association study. The data was collected at Sichuan Provincial People's Hospital from May 2014 to March 2018. TLR4 functional single nucleotide polymorphisms (SNPs), including rs4986790 and rs4986791, were genotyped by SNaPshot method. Genotype and allele frequencies of the two SNPs were evaluated. This study was approved by the Institutional Review Boards of the Sichuan Academy of Medical Sciences & Sichuan Provincial People's Hospital (No.2016-58), and complied with the guidelines of the Declaration of Helsinki. Written informed consents were obtained from all subjects prior to the study. Results:Allelic association analysis revealed that there were no significant association detected in the allelic distributions between the POAG cases and controls for SNPs rs4986790 ( P=0.317) and rs4986791 ( OR=1.000, 95% CI =0.062 5-16.002 2, P=1.000) in the TLR4 gene. Conditional analysis of the two SNPs did not show any significant difference in genotype and allele frequency between the case and the control groups. No association of the two SNPs with POAG was detected under four different genetic models, including homozygote, heterozygote, dominant and recessive models. Conclusions:Polymorphisms rs4986790 and rs4986791 in the TLR4 gene are not related to POAG in the Chinese cohort.
ABSTRACT
Objective:To determine the expression of the E2F6 transcription factor in human malignant melanoma tissues and cell lines, and to evaluate the effect of E2F6 on proliferation, migration and invasion of a malignant melanoma cell line A375.Methods:Frozen tissues and paraffin-embedded tissue sections were collected from 50 cases of cutaneous malignant melanoma and 30 cases of pigmented nevus in Department of Dermatology, Chongqing Traditional Chinese Medicine Hospital from January 2012 to December 2017. Quantitative reverse transcription-PCR (qRT-PCR) was performed to determine the mRNA expression of E2F6 in the malignant melanoma and pigmented nevus tissues, as well as in 7 malignant melanoma cell lines (HM, A375, WM451, WM35, SK-MEL-1, Hs-695T and MDA-MB-435s) and pigmented nevus cells, and immunohistochemical study and Western blot analysis were conducted to determine the protein expression of E2F6 and β-catenin in the malignant melanoma tissues. An E2F6-inhibiting plasmid and a control plasmid were separately transfected into A375 cells by using a liposome-mediated transfection method, and the E2F6 gene-knockdown efficiency was verified by qRT-PCR and Western blot analysis. Cell counting kit-8 (CCK8) assay, soft-agar plate cloning assay, Transwell migration and invasion assays and 3D cell culture assay were conducted to evaluate the effect of E2F6 gene knockdown on the proliferation, migration and invasion of A375 cells, flow cytometry was performed to detect the cell cycle and apoptosis rate, and Western blot analysis was conducted to determine the protein expression of total β-catenin, activated β-catenin, c-Myc and cyclin D1. The comparison between two groups was carried out by t test, the comparison among several groups by one-way analysis of variance, and multiple comparisons by least significant difference t test; Pearson correlation coefficient was used to analyze the correlation between E2F6 and β-catenin expression in cutaneous malignant melanoma. Results:The E2F6 mRNA expression was significantly higher in the 7 malignant melanoma cell lines than in the pigmented nevus cells (all P < 0.001). qRT-PCR showed that the relative mRNA expression of E2F6 was significantly higher in the cutaneous malignant melanoma tissues (0.000 55 ± 0.000 17) than in the pigmented nevus tissues (0.000 18 ± 0.000 09, t = 3.22, P < 0.001). Both the immunohistochemical study and Western blot analysis showed significantly increased E2F6 protein expression, but decreased β-catenin protein expression in the cutaneous malignant melanoma tissues compared with the pigmented nevus tissues (all P < 0.001). Correlation analysis showed that E2F6 protein expression was negatively correlated with β-catenin expression in the malignant melanoma tissues (immunohistochemical study: r = -0.56, Western blot analysis: r = -0.63, both P < 0.01). After knockdown of the E2F6 gene in A375 cells, the mRNA and protein expression of E2F6 was significantly lower in the E2F6 inhibition group than in the control group ( t = 3.38, 2.76 respectively, both P < 0.001). CCK8 assay showed that the cellular proliferative ability was significantly lower in the E2F6 inhibition group than in the control group ( t = 4.58, P < 0.01) 48 hours after transfection; soft-agar plate cloning assay showed that the colony-formation ratio was significantly lower in the E2F6 inhibition group than in the control group ( t = 2.26, P < 0.001) ; Transwell migration and invasion assays showed that the number of cells crossing the chamber was significantly lower in the E2F6 inhibition group (165 ± 23, 96 ± 11 respectively) than in the control group (376 ± 22, 315 ± 31, t = 3.14, 2.12, respectively, both P < 0.01) ; 3D cell culture assay showed that the cell morphology markedly changed, and the invasive pseudopodia disappeared in the E2F6 inhibition group. Flow cytometry revealed that the proportion of cells at G0-G1 phase and apoptosis rate were significantly higher in the E2F6 inhibition group than in the control group (both P < 0.001). Western blot analysis showed significantly decreased protein expression of β-catenin, activated β-catenin and its downstream target proteins c-Myc and cyclin D1, but significantly increased protein expression of P21 in the E2F6 inhibition group compared with the control group (all P < 0.001) ; additionally, the E2F6 inhibition group showed significantly decreased protein expression of epithelial-mesenchymal transition-related molecules vimentin and N-cadherin, but significantly increased expression of E-cadherin compared with the control group (all P < 0.001) . Conclusions:The E2F6 transcription factor is highly expressed in malignant melanoma. Knockdown of the E2F6 gene in A375 cells can inhibit cell proliferation, migration and invasion by antagonizing the β-catenin signaling pathway.
ABSTRACT

ABSTRACT
The present study was conducted to clarify the psychophysiological relaxation effects of viewing bamboo on university students. Forty healthy Chinese participants enrolled in this study to clarify the psychophysiological relaxation effects of viewing bamboo. The effects of visual stimulation using a pot both with and without a bamboo were recorded by measuring the student's blood pressure, EEG and STAI. We observed that viewing bamboo plants resulted in significantly lower systolic (female, P < 0.001; male, P < 0.001; P < 0.05) and diastolic (female, P < 0.001; male, P < 0.001; P < 0.05) blood pressures, but no changes in the pulse rate (female, P = 0.09; male, P = 0.07; P > 0.05) were observed. The results of the EEG analysis indicated brainwave variation (all P < 0.05) and lower anxiety scores (P < 0.01) after 3 min of viewing bamboo compared with the control. These findings indicate that visual stimulation with bamboo plants induced psychophysiological relaxation effects on adults.

ObjectiveTo investigate the correlation between neutrophil to lymphocyte ratio (NLR) and cerebral microbleeds (CMBs) in patients with acute ischemic stroke.MethodsThe consecutive inpatients with acute ischemic stroke were prospectively enrolled.Gradient echo-T2*-weighted imaging was used to evaluate CMBs and their quantity.Univariate analysis was used to compare the baseline data between the CMB group and the non-CMB group.Multivariable logistic regression analysis was used to identify the independent correlation between NLR and CMBs.ResultsA total of 218 patients with acute ischemic stroke were prospectively enrolled, including 66 (30.3%) with CMBs.The age (64.7±6.6 years vs.66.9±8.6 years;t=2.052, P=0.041), high sensitive C-reactive protein (7.0[2.3-13.9] mg/L vs.8.9[4.0-28.1] mg/L;Z=2.008, P=0.045) and NLR (1.9[1.4-2.9] vs.2.3[1.7-3.6];Z=2.071, P=0.038) in the non-CMB group were significantly lower than those of the CMB group.Multivariate logistic regression analysis showed that NLR (odds ratio 1.276, 95% confidence interval 1.008-1.670;P=0.045) and age (odds ratio 1.044, 95% confidence interval 1.002-1.087;P=0.040) were the independent risk factor for CMBs.Spearman correlation analysis showed that NLR was significantly positively correlated with the severity of CMBs (r=0.210, P=0.007).ConclusionsIn patients with acute ischemic stroke, NLR was associated with CMBs and their severity, suggesting that inflammatory reaction might be involved in the occurrence of CMBs.
ABSTRACT
Objective To investigate the predictive value of neutrophil to lymphocyte ratio (NLR) in peripheral blood for the outcomes in patients with acute intracerebral hemorrhage.Methods Consecutive inpatients with intracerebral hemorrhage diagnosed with the head CT were entolled.The modified Rankin Scale (mRS) was used to evaluate the functional outcomes at 90 d,0-2 wvas defined as good outcome,3-6 were defined as poor outcome,and 6 was defined as death.Univariate analysis was used to compare the demographic characteristics,baseline data,imaging,and laboratory findings between the groups.Multivariate logistic regression analysis was used to determine the independent correlation between NLR and the outcomes,and receiver operating characteristics (ROC) analysis was performed to assess the predictive value of NLR for the outcomes.Results A total of 205 patients with acute intracerebral hemorrhage were enrolled in the study,107 (52.2%) had poor outcome and 57 (27.8%) died.There were significant differences in age (P=0.038),Glasgow Coma Scale (GCS) scores (P=0.001),National Institutes of Health Stroke Scale (NIHSS) scores (P =0.001),neutrophil count (P =0.005),lymphocyte count (P =0.002),NLR (P =0.001),fasting blood glucose (P =0.012),hypersensitivity C-reactive protein (P=0.002),hematoma volume (P =0.005),and proportion of bleeding into the ventricles (P =0.002) between the poor outcome group and the good outcome group.There were significant differences in age (P =0.002),previous stroke (P =0.018),GCS scores (P =0.001),NIHSS scores (P =0.001),neutrophil count (P=0.008),lymphocyte count (P=0.001),NLR (P=0.001),fasting blood glucose (P=0.016),hematoma volume (P=0.001),and proportion of bleeding into ventricle (P=0.002) between the death group and the survival group.Multivariate logistic regression analysis showed that NLR was an independent predictive factor for poor outcome (odds ratio [OR] 2.405,95% confidence interval [CI] 1.613-3.587;P=0.001) and death (OR 2.268,95% CI 1.532-3.358;P =0.001) after adjusting for confounders.The ROC curve analysis showed that NLR had a higher predictive value for poor outcome at 90 d (area under the ROC curve 0.703,95% CI 0.632-0.774;P < 0.001).When the cutoff value was 2.3,the sensitivity and specificity were 61.7% and 72.4%,respectively.NLR also had a predictive value for death within 90 d (area under the ROC curve 0.706,95% CI 0.629-0.786;P =0.003).When the cutoff value was 2.2,the sensitivity and specificity were 63.2% and 72.6%,respectively.Conclusion NLR may have certain predict value for outcomes in patients with acute intracerebral hemorrhage.

ABSTRACT
The methylcytosine dioxygenases TET proteins (TET1, TET2, and TET3) play important regulatory roles in neural function. In this study, we investigated the role of TET proteins in neuronal differentiation using Neuro2a cells as a model. We observed that knockdown of TET1, TET2 or TET3 promoted neuronal differentiation of Neuro2a cells, and their overexpression inhibited VPA (valproic acid)-induced neuronal differentiation, suggesting all three TET proteins negatively regulate neuronal differentiation of Neuro2a cells. Interestingly, the inducing activity of TET protein is independent of its enzymatic activity. Our previous studies have demonstrated that srGAP3 can negatively regulate neuronal differentiation of Neuro2a cells. Furthermore, we revealed that TET1 could positively regulate srGAP3 expression independent of its catalytic activity, and srGAP3 is required for TET-mediated neuronal differentiation of Neuro2a cells. The results presented here may facilitate better understanding of the role of TET proteins in neuronal differentiation, and provide a possible therapy target for neuroblastoma.

Objective To explore influencing factors of postoperation fast-track recovery in patients with thoracoscopic lobectomy and provide support for the concept of fast track surgery in clinically application. Methods A total of 129 patients who underwent thoracoscopic lobectomy were selected and questionnaire were adopted for survey between January 2015 and September 2015. Univariate analysis and multivariable logistic regression analysis were used to screen influencing factors of postoperation fast-track recovery. Results Univariate analysis showed that the influnecing factors of postoperation fast-track recovery in patients with thoracoscopic lobectomy were closely related to the age, combined basic disease or not,smoking index,preoperative smoking cessation time,preoperative pulmonary function training or not,systematic health education or not,postoperative wound pain,early postoperative ambulation or not,postoperative chest exercises in time or not (t=2.880,χ2=0.219-33.224, P<0.01 or 0.05). Multivariable logistic regression analysis showed that systematic health education or not, postoperative wound pain,preoperative pulmonary function training or not,postoperative chest exercises in time or not,combined basic disease or not,smoking index,and quit smoking more than two weeks or not were the independent risk factors. Conclusions For the patients with thoracoscopic lobectomy, preoperative condition and postoperative condition in the early should be assessed in time. Controlling the pain effectively,giving reasonable guidance of preoperative pulmonary function exercise,strengthening the respiratory tract management,systematic health education,improving the ward environment,high quality of social support and other diversified services could accelerate the recovery of the postoperative patients.
ABSTRACT
Objective To evaluate the influence of Chinese patent medicine Banlangen Granules and Ganmao Qingre Granules on war‐farin anticogulation effect during the process for treating acute upper respiratory tract infection in the postoperative patients with mechanical valve replacement in order to provide the theoretical reference for clinical medication .Methods The patient receiving mitral valve replace‐ment ,aortic valve replacement or double‐valve replacement and long term postoperative oral warfarin anticoagulation treatment were select‐ed ,moreover the symptoms of complicating acute upper respiratory tract infection occurred .The patients were divided into 2 groups ,30 cases in each group .The group A adopted oral Banlangen Granules ,while the group B was treated by oral Ganmao Qingre Granules .The treat‐ment course was 3 d .The International Normalized Ratio (INR) in the two groups was monitored before medication ,at 72 h after medication and at 72 h after drug withdrawal .Complicating bleeding or embolism reaction was observed .The INR values at various time points were compared between the two groups and the INR values in each group were compared among 3 time points .Results The INR values in the Banlangen Granules group had statistical differences between 72 h and other two time points ,and the INR values at the same time point had statistical difference compared with the Ganmao Qingre Granules group (P0 .05) .Thirty cases had no complication occurrence .The Ganmao Qingre Granules group had no statistical difference among various time points (P>0 .05) ,thirty cases had no complication occur‐rence .Conclusion The warfarin combined with Banlangen Granules causes the INR value increase ,while warfarin combined with Ganmao Qingre Granules has no impact on the INR value ,therefore which suggests that the combination use of warfarin and Banlangen Granules should be cautious in clinic .
