Contemporary Chinese medicine supposes that the blood stasis is a pivotal pathogenic mechanism of coronary heart disease (CHD). The presentation and pathological changes in acute cardiovascular events of CHD, however, seem to exceed the etiological category of blood stasis. The toxin or the combination and transformation of toxin and blood stasis of Chinese medicine are involved in the pathogenesis of CHD according to the basic theory of Chinese medicine. Therefore, to establish a criterion of differentiation and diagnosis for stable CHD caused by etiological toxin of Chinese medicine applying clinical epidemiological method, which is correlated to concept of evidence based medicine, is significant in early recognizing high risk patients and improving treatment of CHD.

None of them were infected with COVID-19, achieving zero infection among medical staff. Conclusion: Although the task of assisting Wuhan was tight in time, and materials and heavy, under the leadership of the team leader and the cooperation of all the staff, all measures were implemented, the training covered all the staff, and high-tech means were introduced to optimize the control strategy, achieving the goals of zero infections among medical staffs and zero cross infections among patients.

Since 1980s, the treatment of acute myocardial infarction (AMI) has entered the era of revascularization of infarction-related artery. There is still shortness of ideal strategy in modern medicine for comprehensive intervention aiming at the complex pathological links such as myocardial no-reflow, slow-reflow and reperfusion injury after revascularization. Therefore, combining traditional Chinese medicine with modern medicine, selecting effective drugs or prescriptions, and exploring their effective ingredients and portions of them as well as the mechanisms of the combinations in promoting myocardial capillary angiogenesis and cardiac muscle cell differentiation, and regulating the repairing process of inflammatory reaction will provide new intervening target directions and comprehensive intervening patterns for the prevention and treatment of AMI.

OBJECTIVETo observe the effect of Tribuli saponins (TS) on left ventricular remodeling after acute myocardial infarction (AMI) in rats with hyperlipemia.

METHODSA composite model of myocardial infarction and hyperlipemia was established and treated with TS to observe its effect on cardiac structure and function by echocardiography.

RESULTS(1) Cardiac function: As compared with the model group, the fractional shortening (FS) and ejection fraction (EF) got increased, and the left ventricular end diastolic volume (LVEDV) and systolic volume (LVESV) got lower in the groups treated with high dose TS and simvastatin (P < 0.05 or P < 0.01), but difference between the two treated groups was insignificant. (2) Cardiac structure: As compared with the model group, the left ventricular dimension end diastole (LVDd) and systole (LVDs) in the groups treated with high dose TS and simvastatin got lower (P < 0.05 or P < 0.01). No treatment showed any effect on the thickness of ventricular wall. (3)Ventricular weight index: Both high dose TS and simvastatin could decrease the left ventricular weight index (LVWI) (P < 0.05).

CONCLUSIONTS could attenuate the left ventricular remodeling after acute myocardial infarction to certain extent, and improve cardiac function in the early phase after AMI, thus playing an important role in controlling morbidity and mortality of cardiac events and long-term prognosis.

OBJECTIVETo evaluate the safety and efficacy of Xiongshao Capsule (XS), consisting of Chuangxiongol and paeoniflorin, in preventing restenosis after percutaneous coronary intervention (PCI) in senile coronary heart disease (CHD) patients.

METHODSA multi-center, randomized, double-blind, placebo-controlled trial was conducted. A total of 335 CHD patients were randomly assigned to treatment with oral administration of XS, or a placebo for 6 months after successful PCI. A clinical follow-up was performed at 1, 3 and 6 months after PCI and an angiographic follow-up was scheduled at 6 months. The primary endpoint was angiographic restenosis defined as a luminal stenosis ≥ 50% in follow-up. The secondary endpoints were combined incidence of death, target lesion nonfatal myocardial infarction, repeat target-vessel angioplasty, and coronary artery bypass graft surgery (CABG). The follow-up for the above clinical endpoint events was continued to 1 year after PCI.

RESULTSThe subgroup analysis of 152 senile patients (68 cases angiographic follow-up) showed that the restenosis rates tended to reduce in the XS group as compared with that in the placebo group (24.32% vs. 38.71%, P > 0.05), and the minimum lumen diameter (MLD) significantly increased in the follow-up (2.15 ± 0.84 for XS vs. 1.73 ± 0.91 for placebo, P < 0.05). The incidence of recurrent angina at 3 and 6 months after PCI was also significantly reduced in the XS group (4.11% and 12.33%) as compared with those in the placebo group (17.72% and 43.04%), but there was no significant difference in the combined incidence of clinical outcomes (6.85% in the XS group vs. 11.39% in the placebo group, P > 0.05). No significant adverse reactions occurred within the 6-month follow-up period in the XS group.

CONCLUSIONAdministration of XS in addition to standardized Western medication for 6 months is demonstrated to be safe and effective in reducing post-PCI recurrent angina and inhibiting luminal restenosis after PCI in senile CHD patients.

OBJECTIVETo explore the tongue manifestations for the blood-stasis and toxin syndrome in the stable patients of coronary heart disease (CHD) according to the acute cardiovascular events (ACEs) in one-year follow-up which based on the pathogenesis hypothesis of "blood-stasis and toxin causing catastrophe".

METHODSTotally 254 stable CHD cases were enrolled after diagnosed by coronary angiography, their tongue appearances were recorded by the digital camera of uniform type, 29 cases with ACEs during one-year follow-up were assigned in ACEs group. The non-ACEs were matched in proportion of 2:1 according to the gender, age (±2.5 years), diabetes mellitus history and previous acute coronary syndrome hospitalization history in the non-ACEs group, and 54 cases were eligibly included. The differences of tongue appearance between the ACEs and non-ACEs group were compared.

RESULTSFifteen cases manifested with bluish tongue (including bluish-grounding or bluish purple tongue), among which 11 cases (37.9%) in the ACEs group and four cases (7.4%) in the non-ACEs group, and there was significant difference (P<0.002). Twenty six cases showed yellow tongue coating in the non-ACEs group, which was significantly higher than that in the ACEs group (48.1 vs. 10.3%, P=0.001). The tongue of sticky greasy coating was more frequently occurred in the non-ACEs group than that in the ACEs group (66.7% vs. 41.4%, P=0.026). The proportion of purplish-red sublingual vessel was higher in the ACEs group than that in the non-ACEs group (41.4% vs. 20.4%, P=0.041). Odd ratio (OR) analysis showed that the patients with bluish tongue, purplish-red sublingual vessel, dry-greasy or dirty greasy coating were more likely to experience ACEs during one-year follow-up (OR: 11.67, 95%CI: 3.34 year 3.34-40.81, P<0.001; OR: 2.76, 95%CI: 1.02 1.02-7.44, P<0.05; OR: 3.12, 95%, CI: 0.89 0.89-10.92, P=0.066).

CONCLUSIONSThe bluish tongue (including bluish-grounding or bluish purple tongue) and purplish-red sublingual vessel were potential tongue manifestations of blood-stasis and toxin. The tongue coating changing from sticky greasy to dry greasy or dirty greasy was also probably a tongue manifestation of "transforming toxin", which need demonstration by further study.

OBJECTIVETo analyze the expression level of candidate tumor suppressor gene N-Myc downstream-regulated gene 2 (NDRG2) in human colon cancer.

METHODSThirty samples of colon cancer tissues with matched normal colon tissues were collected. The NDRG2 mRNA level was detected by semi-quantitive RT-PCR and the NDRG2 protein level was examined by Western blot and immunohistochemistry.

RESULTSTwelve samples of colon cancer tissues had low NDRG2 mRNA level and low protein level. The positive rates of NDRG2 in normal tissues and the tumorous colon tissues were 90.0%(27/30) and 53.3%(16/30) by immunohistochemistry respectively. There was a significant difference between two groups (P<0.05). The NDRG2 expression was not correlated with age, sex, metastasis of lymph node, depth of infiltration, as well as the Dukes staging(P>0.05), while it was correlated to the histology grading. The positive rate of NDRG2 in the well- and moderate-differentiation group was higher than that in the poor-differentiation group(P<0.05).

CONCLUSIONThe expression of NDRG2 is low in some colon cancer tissues, which indicates that the low level of NDRG2 expression may be engaged in the development of colon cancer.

OBJECTIVETo evaluate the application of fluorescence in-situ hybridization (FISH) in detection of gene translocation in paraffin-embedded tissue samples of synovial sarcoma.

METHODSInterphase FISH was carried out in paraffin-embedded tissue of 42 cases of synovial sarcoma and 9 cases of non-synovial sarcoma, using a LSI SYT (18q11.2) dual color break-apart probe. In all of the cases studied, the gene fusion product SYT-SSX was also analyzed by reverse transcription-polymerase chain reaction (RT-PCR).

RESULTSPositive signals were detected in 37 cases (88.1%) of synovial sarcoma by FISH, as compared with 35 cases (83.8%) by RT-PCR and 39 cases (92.9%) by both techniques. Of the 39 positive cases, 33 cases (78.5%) revealed SYT gene translocation.

CONCLUSIONSFISH may serve as an adjunctive diagnostic tool in problematic cases of synovial sarcoma and can be applied in paraffin-embedded tissue samples. As compared with RT-PCR, FISH is also sensitive and reliable. The methodology is less labor intensive and time consuming. FISH has great potential in molecular diagnosis of soft tissue tumors.
