Objective To evaluate the clinical efficacy of Qilinxintongshu pill for treatment of critical patients with unstable angina pectoris (UAP) accompanied by upper alimentary tract damage.Methods A prospective randomized controlled trial was conducted. A total of 60 critical outpatients or inpatients with confirmed diagnosis of UAP accompanied by upper alimentary tract damage in Cardiology Department of Hospital of Traditional Chinese Medicine of Qionghai City from November 2011 to January 2015 were enrolled in the study, and they were assigned to a therapy group (30 cases) and a control group (30 cases) by table of random number. The conventional medical basic therapy was given to both groups, in addition, the patients in therapy group took Qilinxintongshu pill (made of notoginseng, dragon's blood, fruit of immature citron, etc.) 5 g once, three times a day, and the patients in control group orally administered clopidogrel 75 mg once a day, the therapeutic course being consecutive 30 days. After treatment, the rates of main cardiovascular events [including death, a newly-happened myocardial infarction (MI), and obstinate ischemia] and events of alimentary damage were compared between the two groups, and adverse effects were observed.Results There was no statistically significant difference in incidence of cardiovascular events between the therapy group and control group [6.7% (2/30) vs. 16.7% (5/30),P > 0.05]. The incidence of massive hemorrhage of gastrointestinal tract was significantly lower in therapy group than that in control group [10.0% (3/30) vs. 36.7% (11/30),P < 0.05]. In the treatment process, there was no significant untoward side effect, and no abnormalities in routine blood and urine tests, liver and renal functions were found.Conclusion Qilinxintongshu pill for treatment of critical patients with UAP accompanied by upper alimentary damage is safe and effective, and does not enhance the incidence of massive hemorrhage of gastrointestinal tract.

Objective To observe the therapeutic effect of Qilin Xintongshu pill for treatment of patients with non-ST segment elevation acute coronary syndromes(NSTE-ACS)accompanied by gastrointestinal bleeding (GIB). Methods A prospective randomized controlled trial was conducted. A total of 67 hospitalized patients in Cardiovascular Department of Qionghai City Hospital of Traditional Chinese Medicine were divided into therapy group(35 cases)and control group(32 cases). Both groups were given conventional medical treatment(except anti-coagulative agent). In the therapy group,the patients received Qilin Xintongshu pill(the ingredients consisting of panax pseudo-ginsen,dragon's blood,immature orange fruit,etc.)oral administration,once 5 mg and 3 times a day,while in the control group,the patients accepted clopidogrel orally,once 75 g and once a day,the therapeutic course in both groups being 30 days. The major cardiovascular events(such as death,a newly-happened myocardial infarction(MI),MI secondary,obstinately ischemia)and incidence of massive hemorrhage of gastrointestinal tract were compared between the two groups,and the adverse events were observed. Results After treatment,the incidence of cardiovascular events and massive hemorrhage of gastrointestinal tract in the therapy group were decreased significantly compared to those in the control group 〔incidence of cardiovascular events:8.57%(3/35)vs. 28.13%(9/32), incidence of massive hemorrhage of gastrointestinal tract:2.86%(1/35)vs. 21.88%(7/32),both P<0.05〕. Adverse events were not observed in both groups,and the examinations of blood,urine,liver and renal functions were of no abnormalities before and after treatment. Conclusion Qilin Xintongshu pill can effectively reduce the incidences of cardiovascular events and massive hemorrhage of gastrointestinal tract in patients with NSTE-ACS accompanied by GIB in the therapeutic course of 30 days,therefore this traditional Chinese herbal medicine is an ideal agent for treatment of such disease.

Objective To analyze the expression characteristics of excision repair cross-complementing 1 (ERCC1), topoisomeraseⅡ (TOPOⅡ), ribonucleotide reductase M1 (RRM1), β3-tubulin and thymidylate synthase (TS) in lung cancer and their associations with the pathological types. Methods The immunohistochemical EnVision method was used to determine the expression of ERCC1, TOPOⅡ, RRM1,β3-tubulin and TS in 548 patients who were diagnosed as lung cancer from January 2011 to December 2014. Variance analysis was performed to analyze their expression characteristics among different pathological types and correlation. Results The expression positive rates of ERCC1, TOPOⅡ, RRM1, β3-tubulin and TS were 61.86 % (339/548), 91.06 % (499/548), 62.59 % (343/548), 73.18 % (401/548) and 70.44 % (386/548), respectively. The expression of ERCC1 was weak positive mostly (P<0.05), meanwhile the expression of TOPOⅡ was medium-strong positive mostly (P<0.05). In ERCC1 group, the positive rate of squamous cell carcinoma was higher than that of adenocarcinoma [57.39 % (167/291) vs. 42.61 % (124/291), P=0.000]. In weak positive of TOPOⅡ group, the proportion of adenocarcinoma was higher than that of squamous cell carcinoma [23.58 % (100/137) vs. 8.73 % (37/137), P=0.000]. In medium-strong positive of TOPOⅡ group, the proportion of squamous cell carcinoma was higher than that of adenocarcinoma [47.41 % (201/287/) vs. 20.28%(86/287), P=0.000]. The expressions of ERCC1, TOPOⅡ, RRM1,β3-tubulin and TS were irrelevant (r=0.4, P=0.397). Conclusions The expressions of ERCC1 and TOPOⅡ are higher in squamous cell carcinoma than those in adenocarcinoma. The expression of ERCC1 is weak positive mostly, meanwhile the expression of TOPOⅡis medium-strong positive mostly. There is no correlation between them.

AIM: To investigate the effects of myocardial remodeling of aged left atrium (LA) on atrial ar-rhythmogenesis in rabbits .METHODS:The male New Zealand rabbits were divided into young LA and aged LA groups . By observing the changes of monophasic action potential ( MAP) and burst-pacing in LA of the rabbits in vivo, the main cardioelectrophysiological parameters such as resting membrane potential ( RMP) , action potential amplitude ( APA) , ma-ximum rise veloctiy of action potential (dv/dtmax), plateau potential and action potential duration at 30%, 50%and 90%( APD30 , APD50 and APD90 ) , as well as the inducibility and duration of atrial arrhythmias were recorded .L-type calcium current (ICa,L) was analyzed via whole-cell patch-clamp technique in enzymatically dissociated single rabbit LA myocytes . The myocardial collagen content was quantified after Masson staining , and the ultrastructure of the LA cells was observed under scanning electron microscope .The expression of Cav 1.2 in LA tissue of the 2 groups was detected by Western blot . RESULTS:Compared with young LA group , dv/dtmax and plateau potential were significantly decreased , APD30 and APD50 were shortened, and APD90 was notably prolongated in aged LA group (P<0.01).The inducibility or duration of atrial arrhythmias was severely increased or prolongated in aged LA group (P<0.01).With voltage clamp model, the den-sity of ICa,L in aged LA group was significantly decreased , and current-voltage curve was notably moved upward compared with young LA group.When the clamp potential was +20 mV, the density of ICa,L was notably modified from (11.72 ± 1.39) pA/pF in young LA group to (6.08 ±0.98) pA/pF in aged LA group ( P<0.01).Compared with young LA group, the protein level of collagen was significantly increased (P<0.01), and the arrange of atrial myocytes was irregular in LA of rabbits in aged LA group .The atrial myocytes of the LA wall in aged LA group exhibited abnormal ultrastructural alterations , such as karyopyknosis , irregular and swelling mitochondria with the presence of vacuoles , and mild and severe sarcomere degeneration .Compared with those in LA tissues of young rabbits , the expression levels of Cav 1.2 in the LA tis-sues of aged rabbits were severely reduced (P<0.01), and had a significant positive correlation with the reduction of ICa,L (r=0.83, P<0.01).CONCLUSION:The pathophysiological characteristics of aged LA are significantly altered , and might contribute to vulnerability and susceptibility of occurrence of atrial fibillation in aged rabbits .The mechanisms might completely attribute to the notable reduction of ICa,L , abnormal alterations of ultrastructures and obvious decrease in the ex-pression of Cav1.2 in the aged LA of aged rabbits .
