Objective:To evaluate the clinical effect of Guanxin Tongmai plaster combined with conventional western medicine in the treatment of phlegm and blood stasis syndrome of coronary heart disease and angina pectoris.Methods:A total of 60 patients in the Department of Cardiology of the Affiliated Hospital of Liaoning University of Traditional Chinese Medicine (TCM) from February to August 2020 who met the inclusion criteria were randomly divided into two groups with 30 in each group. Both groups were treated with conventional western medicine. On this basis, Guanxin Tongmai plaster was applied at the acupoints in the treatment group and placebo plaster was applied in the control group. TCM syndrome score was performed before and after treatment, angina score was evaluated from three aspects of angina attack frequency, duration and pain degree, and blood lipid TG, TC, LDL-C and HDL-C were detected by enzyme quantitative method. The blood homocysteine (Hcy) was detected by enzyme circulation method, the ECG and the nitroglycerin reduction rate were recorded, and the safety index was detected according to the ECG changes.Results:In the treatment period, 2 patients in the treatment group fell off, 3 in the control group. A total of 28 patients in the treatment group and 27 in the control group were analyzed. The total effective rate of ECG efficacy in the treatment group was 67.9% (19/28) and the control group was 48.1% (13/27). There was significant difference between the two groups ( χ2=4.46, P=0.040). After treatment, the TCM syndrome score and angina score in the treatment group were significantly lower than those in the control group ( t values were 9.12 and 4.45, P values were 0.004 and 0.042, respectively). The reduction rate of nitroglycerin in the treatment group was 82.1% (23/28) and 55.6% (15/27) in the control group. There was significant difference between the two groups ( χ 2=4.72, P=0.030). After treatment, the plasma TG, TC, LDL-C in the treatment group were significantly lower than those in the control group ( t values were 4.17, 6.57 and 6.52, P<0.05 or P<0.01), the level of HDL-C was significantly higher than that of the control group ( t=7.07, P=0.010), and the level of plasma Hcy was significantly lower than that in the control group ( t=6.70, P=0.012). There was no significant difference in liver, kidney and coagulation function between the two groups. Conclusion:Guanxin Tongmai plaster combined with conventional western medicine can improve the clinical symptoms of patients with coronary heart disease and angina pectoris, reduce the level of blood lipid and Hcy, and improve the clinical curative effect.

Objective:To explore the risk factors of spontaneous rupture of hepatocellular carcinoma (HCC), and to analyze the prognosis of transcatheter arterial embolization (TAE) in the treatment of spontaneous rupture of HCC.Methods:From January 2008 to December 2018, at Tianjin Third Central Hospital, 126 patients diagnosed with spontaneous rupture of HCC (spontaneous rupture group) and in the same period 252 patients diagnosed as HCC without rupture (non-spontaneous rupture group) were retrospectively selected. Independent sample t test, Mann-Whitney U test and chi-square test were used to compare the general data, laboratory test results and imaging results between spontaneous rupture group and non-spontaneous rupture group. Multivariate logistic regression was used to analyze the independent risk factors of spontaneous rupture of HCC. Kaplan-Meier method and log-rank test were used for survival analysis of 92 patients treated with TAE and 31 patients treated with conservative treatment in patients with spontaneous rupture of HCC, and multivariate Cox proportional hazard regression was used to analyze the independent prognostic factors of patients treated with TAE. Results:The proportions of tumor maximum diameter ≥5 cm, tumors mainly located in segment Ⅱ, Ⅲ, Ⅳ and Ⅵ of the liver, tumors protruding height from the surface of liver ≥1 cm, liver cirrhosis and portal vein thrombosis (PVT) in spontaneous rupture group were all higher than those in non-spontaneous rupture group (46.8%, 59/126 vs. 35.7%, 90/252; 61.1%, 77/126 vs. 46.0%, 116/252; 73.0%, 92/126 vs. 18.7%, 47/252; 81.7%, 103/126 vs. 69.0%, 174/252; 20.6%, 26/126 vs. 11.5%, 29/252), and the level of fibrinogen is lower than that in non-spontaneous rupture group ((3.07 ±1.38) g/L vs. (3.92±1.13) g/L), and the differences were statistically significant ( χ2=4.343, 7.644, 106.780, 6.918 and 5.628, t=-3.276, all P<0.05). The results of multivariate logistic regression analysis showed that the location of tumors in segment Ⅱ, Ⅲ, Ⅳ, Ⅵ of the liver, the height of tumors protruding from the surface of liver ≥1 cm, liver cirrhosis and the fibrinogen was lower than the lower limit of the reference value were independent risk factors of spontaneous rupture of HCC (odds ratio ( OR)=1.354, 5.726, 1.152, 1.892; 95% confidence interval ( CI) 1.062 to 2.008, 1.049 to 19.575, 1.016 to 1.895, 1.267 to 3.346; all P<0.05). Among 92 patients with spontaneous rupture of HCC treated with TAE, the TAE technical success rate and clinical success rate were 100.0% (92/92) and 93.5% (86/92), respectively. Thirty-one patients received conservative treatment. The median survival time of the patients treated with TAE was 243 d (38 d, 377 d), which was about 10 times that of the patients who accepted conservative treatment (23 d (9 d, 51 d)). The 1-month, 3-month, 6-month, 1-year and 3-year survival rates of the patients treated with TAE were 72.8%, 50.8%, 46.0%, 31.1% and 13.6%, respectively, and those of patients who accepted conservative treatment were 25.8%, 17.2%, 11.5%, 5.7% and 0, respectively; and the differences in survival rates between the two groups were statistically significant ( χ2=34.606, P<0.01). Log-rank test analysis showed that initial hemoglobin <60 g/L, C grade of liver function, total bilirubin (TBil)≥50 μmol/L, complicated with portal vein tumor thrombus, hepatic lobe embolism during TAE, and tumor maximum diameter ≥10 cm were all correlated with poor survival rates of patients with spontaneous rupture of HCC after TAE ( χ2=3.752, 4.146, 22.318, 4.087, 5.685 and 7.893, all P<0.05). The results of multivariate Cox proportional hazard regression analysis showed that TBil ≥ 50 μmol/L, hepatic lobe embolism during TAE, and tumor maximum diameter ≥10 cm were independent factors of poor prognosis of spontaneous rupture of HCC treated with TAE ( OR=25.873, 8.415, 18.620; 95% CI 4.916 to 126.005, 1.136 to 27.319, 2.754 to 84.368; all P<0.05). Conclusions:In HCC patients with tumors located in segments Ⅱ, Ⅲ, Ⅳ and Ⅵ of the liver, the height of tumors protruding from the surface of liver ≥1 cm, liver cirrhosis or the fibrinogen is lower than the lower limit of the reference value, close attention should be paid to the risk of spontaneous tumor rupture. TAE is an effective treatment for acute spontaneous rupture of HCC, and the prognosis of patients treated with TAE is better than that of patients receiving conservative treatment. However, patients with TBil ≥50 μmol/L, hepatic lobe embolism during TAE and tumor maximum diameter ≥10 cm have a poor prognosis after TAE treatment.

Objective To analyze the impact of the differences in blood supply to hepatic hemangiomas on interventional treatment effectiveness and complications.Methods A retrospective study was conducted on 322 patients with liver hemangiomas treated from January 2008 to December 2015 in Tianjin Third Central Hospital.The hemangiomas were diagnosed and classified into 3 groups according to the blood supply to the hemangioma:the rich blood supply group (n =128),the moderate blood supply group (n =104) and the poor blood supply group (n =90).The hemangiomas were embolized via the hepatic artery,and the therapeutic effect and complication were compared and analyzed among the 3 different groups.The mean follow-up was 12 months.Results The therapeutic effect of hepatic artery embolization was optimal for the rich blood supply group in the first 3-months of follow-up (the significant efficiency,effective rates were 18.8％ and 35.2％ respectively).There was no significant difference between the rich blood supply group and the moderate blood supply group at 12th month follow-up.The treatment effect on the poor blood supply group was significantly worse than the other two groups on follow-up.Complications after treatment occurred most commonly in the rich blood supply group and it was the least common in the poor blood supply group (the incidence rates were 43.8％,36.6％ and 8.9％ respectively).However,severe post-treatment complications were apparently more common in the poor blood supply group than the other two groups.Conclusions The therapeutic effects of transcatheter arterial embolization on hepatic hemangioma can differ because of the diversity in blood supply.In clinical practice,attention should be paid to the proper choice of treatment according to the blood supply to the lesion.Serious complications can occur after treatment.

Objective To analyze the efficacy and complications of interventional treatment in hepatic hemangiomas with poor blood supply,and to explore the mode of treatment.Methods From May 2013 to October 2016,at Tianjin Third Central Hospital,82 patients with hepatic hemangiomas with poor blood supply were enrolled and divided into intervention group,puncture group and combination group.Conventional hepatic artery intubation was performed in intervention group,using a microcatheter to superselect to hemangioma and injecting pingyangmycin-lipiodol emulsion into the tumor of hemangioma.Patients of puncture group underwent the ultrasound-guided percutaneous liver puncture,and the pingyangmycin-lipiodol emulsion was injected into the tumor.The patients of combination group first received intervention treatment,and the pingyangmycin-lipiodol emulsion were injected again into the tumor area lacking of iodized oil deposition through percutaneous transhepatic puncture.After treatment,the complications and clinical efficacy of patients in three groups were evaluated and the reasons of patients lost to follow-up were analyzed.The analysis of variance,Chi-square test and Fisher's exact test were performed for statistical analysis.For patients lost to follow up,intention-to-treat (ITT) analysis and per protocol (PP) analysis were used.Results Among 82 patients with hepatic hemangiomas with poor blood supply,there were 27 in intervention group,24 in puncture group and 31 in combination group.Seven patients developed serious complications such as liver failure.At three months after the treatment,the overall efficacy of combination group (20.9％,9/31) was higher than that of intervention group (7.4％,2/27) and puncture group (4.2 ％,1/24),and the differences were statistically significant (x2 =6.296,P =0.014;x2 =5.622,P =0.031).At six months after the treatment,the overall efficacy of combination group (ITT analysis 70.3 ％,26/37;PP analysis 71.0 ％,22/31) was still higher than that of intervention group (40.9％,9/22) and puncture group (7/18),and the differences were statistically significant (ITT analysis x2 =4.929 and 4.969,PP analysis x2 =4.789 and 4.851;all P＜0.05).At twelve months after the treatment,a total of 41 patients of three group were lost.Among them,the patients with ineffective treatment by clinical effect evaluation accounted for 63.4％ (26/41),which was higher than those with significantly effective treatment (12.2 ％,5/41) and those with effective treatment (24.4 ％,10/41),and the differences were statistically significant (x2=22.873 and 12.676,both P＜0.01).Conclusions The efficacy of the interventional treatment alone for hepatic hemangiomas with poor blood supply is poor and the complications should be considered when selecting the appropriate treatment methods.

OBJECTIVETo assess the value of detecting the compositional features of carotid atherosclerotic plaques by 3.0T high resolution magnetic resonance imaging (MRI) in patients with coronary artery disease (CAD).

METHODSConsecutive 104 patients with coronary atherosclerosis confirmed by coronary angiography were prospectively recruited from January 2013 to January 2015 in Tiantan hospital. All patients were imaged with 3.0T high resolution MRI system. After exclusion patients with poor image quality, 97 patients were divided into 3 groups according to the degree of coronary artery stenosis: coronary atherosclerosis group (coronary stenosis between 1%-49%, n=16); single-vessel lesion group (single vessel lesion with stenosis between 50%-100%, n=48); multi-vessel lesion group (two or three vessel lesions with stenosis between 50%-100% or left main stem disease, n=33). The prevalence of total carotid plaque, calcified plaque, lipid-rich necrotic core, intra-plaque hemorrhage, plaque ulcer and rupture were compared among 3 groups.

RESULTSThe prevalence of total carotid plaque (81.3%(13/16), 72.9%(35/48), and 93.9%(31/33)) and calcified plaque (50.0%(8/16), 35.4%(17/48), and 42.4%(14/33)) were similar among the 3 groups (both P>0.05). The prevalence of carotid lipid-rich necrotic core in coronary atherosclerosis group was significantly lower than in single-vessel lesion group (18.8%(3/16) vs. 64.6%(31/48), P<0.01) and multi-vessel lesion group(18.8%(3/16) vs. 69.7%(23/33), P<0.01), but there was no significant difference between single-vessel lesion group and multi-vessel lesion group(P>0.05). Intra-plaque hemorrhage was detected in 2 patients of multi-vessel lesion group. There was no plaque ulcer or rupture in this cohort.

CONCLUSIONCarotid plaque features are associated with the severity of coronary atherosclerosis in CAD patients.

Objective To explore the safety and feasibility of coronary angiography (CAG) via percutaneous left radial artery approach (LRA) compared with right radial artery approach (RRA) in aged patients, and determine whether LRA is a valid alternative for CAG. Methods A total of 502 consecutive patients who were aged 65 or older underwent diagnostic CAG were recruited and randomized to the LRA group (240 patients) or RRA group (262 patients). The study end points included total procedural duration, coronary time, fluoroscopy time, dose of radiation including cumulative air kerma and dose area product, contrast volume, and the incidence of vascular complications. Results Coronary procedural success rate was 96.2%(231/240) in LRA group and 96.2%(252/262) in RRA group. There was no significant difference (P>0.05). The radial cannulation time, fluoroscopy time, look through time, dose of radiation, contrast volume and the percentage of hydrophilic wire used in two group had no significant difference (P > 0.05). The catheter in place time in LRA was significantly shorter than that in RRA group:(2.7 ± 2.5) min vs. (3.3 ± 3.3) min, P=0.036). There was a trend toward shorter procedural duration in LRA group than that in RRA group, but there was no significant difference: (13.3 ± 6.1) min vs. (14.3 ± 6.2) min, P=0.075. Conclusions LRA approach has similar safety and feasibility in terms of performing coronary angiography compared with RRA.It seems to be a feasible alternative for CAG in aged patients.

Objective To observe the changes of eosinophils (EOS) in peripheral blood in patients with acute myocardial infarction (AMI).To investingate the association of EOS in peripheral blood and acute myocardial infarction.Methods The single-centre study enrolled 50 acute myocardial infarction patients (23 cases were NSTEMI and 27 cases were STEMI) who were treated in Beijing Tiantan Hospital from January 2014 to July 2014.Fifty medical individuals who were randomly chosen from the same period of time.White blood cell counts,EOS counts and percentages, levels of Troponin Ⅰ of all individuals were determined.Compare White blood cell counts,EOS counts and percentages between two groups.Association of EOS in peripheral blood and Troponin Ⅰ in patients with acute myocardial infarction was evaluated by Pearson correlation.Results The levels of eosinophils counts ((0.02±0.01) × 109/L vs.(0.24±0.14) × 109/L) and percentages ((0.40±0.49) ％ vs.(1.25±0.54)％) in AMI patients were significantly lower than those in the control group (t =11.083, P＜0.01;t=8.242,P＜0.01).There was significant inverse correlation between EOS counts and percentage and levels of Troponin Ⅰ(r=-0.390,-0.387;P＜0.05).Conclusion Patients with acute myocardial infarction presented decreased eosinophils counts and percentages.EOS counts and percentage and levels of Troponin Ⅰ presented negative correlation.It was close relation of EOS and acute myocardial infarction.

[Objective]To study the effect of curcumin on the cholesterol metabolism of nonalcoholic fatty liver disease(NAFLD) cells model induced in vitro and its potential mechanism. [ Methods]The cellmodel of nonalcoholic fatty liver disease(NAFLD) was established by oleic acid and treated with curcumin. The method of oil red O staining was used to observe accumulation of intracellular lipid while the intracellular content of TG, FC and TC was detected by enzymatic method. Meanwhile, the mRNA levels of SR-BΙand HMGCR were detected with qPCR.[ Results] The NAFLD cellmodel was successful y established by culturing with 30 μg·mL-1 oleic acid. After curcumin intervention, TG, FC and intracellular lipid accumulation levels were significantly reduced in NAFLD cellmodel. Meanwhile, curcumin can reduce HMGCR mRNA expression and raise SR-BΙ mRNA expression. [Conclusion] Curcumin can decrease FC level in NAFLD cellmodel and the mechanism might be related with its capacity of restraining endogenous cholesterol biosynthesis and promoting foreign cholesterol transfer into the liver cells for metabolism.

Objectives To analyze the characteristics of serum protein electrophoresis(SPE)in chronic heart failure(CHF) patients,evaluate prognostic value and explore the reason of it preliminarily.Methods Retrospective exploration of 6 1 8 chronic heart failure patients in study cohort (CHF cohort)and 70 patients with normal cardiac function in control cohort was made to comp are the difference of serum protein electrophoresis.Then,CHF Patients were tracked down by phone to discuss the correlation between adverse event rate (re-hospitalization rate or mortality rate)and their SPE.Last,the multiple linear regression analysis of SPE and biochemical indicators was made to explore the reason of the abnormality.Results Pa-tients of CHF cohort appeared to have significantly rising beta 1-gobulin(6.01±1.06)%,compared with control cohort(t=3.417,P<0.001).Post-discharge adverse event rate displayed by the curve demonstrated that patients with beta 1-gobulin higher than or equal to 6% had much more adverse event rate than those with beta 1-gobulin less than 6%,in 7 to 24 months after discharged from the hospital,which had been proved by the Chi-square test of 0.031(P<0.05).Multiple linear regres-sion analysis showed that beta 1-globulin and serum creatinine,uric acid,and sodium were significantly correlated.Conclusion CHF patients had higher beta 1-gobulin of SPE probably because of immunoactivation,which may increase their re-hospi-talization rate ormortality rate after hospital discharge.Meanwhile,growing beta 1-gobulin is closely correlated with blood creatinine,uric acid and blood natrium and becomesa risk of kidney dysfunction due to hypoperfusion and accumulation of se-rum immunoglobulin.
