OBJECTIVE: To evaluate the effectiveness of integrative medicine (IM) on patients with coronary artery disease (CAD) and investigate the prognostic factors of CAD in a real-world setting. METHODS: A total of 1,087 hospitalized patients with CAD from four hospitals in Beijing, China were consecutively selected between August 2011 and February 2012. The patients were assigned to two groups based on the treatment: Chinese medicine (CM) plus conventional treatment, i.e., IM therapy (IM group); or conventional treatment alone (CT group). The endpoint was major adverse cardiac events [MACE; including cardiac death, myocardial infarction (MI), and revascularization]. RESULTS: A total of 1,040 patients finished the 2-year follow-up. Of them, 49.4% (514/1,040) received IM therapy. During the 2-year follow-up, the total incidence of MACE was 11.3%. Most of the events involved revascularization (9.3%). Cardiac death/MI occurred in 3.0% of cases. For revascularization, logistic stepwise regression analysis revealed that age ⩾ 65 years [odds ratio (OR), 2.224], MI (OR, 2.561), diabetes mellitus (OR, 1.650), multi-vessel lesions (OR, 2.554), baseline high sensitivity C-reactive protein level ⩾ 3 mg/L (OR, 1.678), and moderate or severe anxiety/depression (OR, 1.849) were negative predictors (P<0.05); while anti-platelet agents (OR, 0.422), β-blockers (OR, 0.626), statins (OR, 0.318), and IM therapy (OR, 0.583) were protective predictors (P<0.05). For cardiac death/MI, age ⩾ 65 years (OR, 6.389) and heart failure (OR, 7.969) were negative predictors (P<0.05), while statin use (OR, 0.323) was a protective predictor (P<0.05) and IM therapy showed a beneficial tendency (OR, 0.587), although the difference was not statistically significant (P=0.218). CONCLUSION In a real-world setting, for patients with CAD, IM therapy was associated with a decreased incidence of revascularization and showed a potential benefit in reducing the incidence of cardiac death or MI.

OBJECTIVETo analyze the efficacy of endoscopic screening for gastric cancer in rural population in high risk areas of upper gastrointestinal cancer in Henan province.

METHODSSubjects aged 40-69 years in the high risk areas were selected to participate in the endoscopic screening based on the cluster sampling, and screening-positive subjects were sampled for pathological examination. The data of screening were summarized and the detection rates of severe chronic atrophic gastritis, severe intestinal metaplasia, low grade intraepithelial neoplasia, high grade intraepithelial neoplasia, early and middle-late cancer were calculated, and the constituent ratio of early cancer cases was calculated. The detection rates and early diagnosis rates for the first round screening and follow-up screening were compared.

RESULTSIn the 5 years, a total of 88 263 subjects were endoscopically examined in the first round screening and 4 004 subjects were diagnosed with low grade intraepithelial neoplasia or above (the detection rate was 4.54%), in which 3 256 cases were with low grade intraepithelial neoplasia (the detection rate of 3.69%), 366 cases with high grade intraepithelial neoplasia (the rate of 0.41%), 199 cases with early cancer (the rate of 0.22%) and 183 cases with middle-late cancer (the rate of 0.21%). The number of cases of high grade intraepithelial neoplasia and early cancer was 565 and the early diagnosis rate was 75.53%. 1 894 subjects with severe chronic atrophic gastritis, severe intestinal metaplasia and low grade intraepithelial were followed up with a compliance of 66.32%. A total of 45 cases of early cancer were diagnosed, with a detection rate of 2.38% and early diagnosis rate of 100%. The detection rate and early diagnosis rate in the follow-up screening were both statistically significantly higher than that in the first round screening (P<0.01 for both).

CONCLUSIONThe efficacy of endoscopic screening for gastric cancer is significant in high risk areas of upper gastrointestinal cancer, and improving the quality of follow-up screening will achieve a better performance of the screening.

OBJECTIVETo evaluate effect of screening of esophageal cancer at rural areas in Henan province.

METHODSAt rural areas with high incidence of upper gastrointestinal carcinoma in Henan province total of 88,263 persons with 40 to 69 years old were set to the target population of the screening by the 12 cities and countries and endoscope and pathology diagnosis were performed during 2009-2013. For patients with precancerous lesions, follow-up visits were conducted and defined as follows: once in three years for patients with mild dysplasia, once per year for moderate hyperplasia patients, the patients with severe intraepithelial neoplasia/carcinoma in situ should be treat, at least once per year for those one who didn't under treatment. The result data of screening were summarized and detection rates of esophagus hyperplasia, carcinoma in situ, early and middle-late cancer were calculated, as well as the early diagnosis rate. The result between first round and follow-up screening was compared.

RESULTSTarget population were examined in first round screening. There were 8,434 persons with above mild dysplasia and the detection rate was 9.56%, among them there were 7,224 (8.18%) cases with light-middle hyperplasia, 789 (0.89%) cases with serious dysplasia or cancer in situ, 239 (0.27%) cases with early cancer and 182 (0.21%) cases with middle-late cancer. The sum of serious dysplasia or cancer in situ and early cancer was 1 028 and the early detection rate was 84.96% (1,028/1,210). From 2012 to 2013, the follow-up screening for persons with light-middle hyperplasia which should be followed 4,230 cases, there were 2 853 people to take in screening and compliance was 67.45%. Total of 94 cases were diagnosed with cancer in situ or early cancer. The detection rate and the early detection rate were 3.29% and 100%, respectively. The rates of detection and early detection in phase of follow-up screening were statistically significantly higher than that in first round screening respectively (P<0.001).

CONCLUSIONAt rural areas of high incidence upper gastrointestinal carcinoma in Henan province, the screening with endoscope had good effect and strengthening the follow-up screening could increase the effect.

OBJECTIVETo investigate the association between obesity and the risk of lung cancer and evaluate a dose-response relationship between body mass index (BMI) and incidence risk of lung cancer in the Chinese population.

METHODSA systematic literature search for BMI and incidence risk of lung cancer in the Chinese population, as well as through the reference lists of retrieved articles. The literature databases including Chinese National Knowledge Infrastructure, Wanfang, PubMed, Embase and Google Scholar. Time range was from the founding of each database to September 2014 and a total of 93 research papers were collected. Meta-analysis was conducted to calculate pooled odds ratio and corresponding 95% CI. Generalized least-squares regression methods were used to make a dose-response meta-analysis between BMI and incidence risk of lung cancer.

RESULTSSeven studies were included in the meta-analysis, with a number of 2 351 lung cancer cases. Results showed that obesity was inversely associated with lung cancer incidence (OR = 0.68, 95% CI: 0.59-0.79) (heterogeneity test: I² = 0, P = 0.594). The association did not change with stratification by study design, sex, smoking status, BMI measurement method and study population. A linear dose-response association between BMI and risk of lung cancer was visually significant, and lung cancer risk would be reduced 21% for per 5 kg/m² BMI increase (OR = 0.79, 95% CI: 0.71-0.89) (heterogeneity test: q = 22.43, P = 0.002).

CONCLUSIONThe results of this meta-analysis indicated that higher BMI was a protective factor against lung cancer, but smoking may play a stronger role as a confounding factor for the most important role with lung cancer incidence.

OBJECTIVETo summarize the results of endoscopic screening of esophageal, gastric cardiac and gastric cancers in the high-risk population, and analyze the influencing factors such as age, gender and biopsy rate on their detection and early diagnosis rates.

METHODSNine high incidence cities and counties of esophageal cancer in Henan province were included in this study. People aged 40-69 years were set to the target population. Excluding contraindications for gastroscopy, in accordance with the national technical scheme of early cancer diagnosis and treatment, gastroscopic screening and biopsy pathology for human esophageal, cardiac and gastric cancers were carried out.

RESULTSDuring the 3-year period, a total of 40 156 subjects were screened. Among them, 18 459 cases of various precancerous lesions (46.0%) were detected. The cancer detection rate was 2.3% (916 cases), including 763 cases of early cancers. The diagnosis rate of early cancers was 83.3%. Precancerous lesions were detected in 9297 cases (23.2%) for esophagus and 9162 cases (22.8%) for gastric cardia as well as stomach, respectively.

CONCLUSIONSThe results of this study demonstrate that endoscopic screening is feasible for early detection, diagnosis and treatment of esophageal, gastric cardia and gastric cancers among high risk population in high incidence area. Exploration analysis of relevant affecting factors may help to further improve the screening project for early diagnosis and treatment of those cancers.

BACKGROUNDDrug-eluting stents (DES) with durable polymer have significantly reduced restenosis and target vessel revascularization compared with bare metal stents. Durable polymer has been linked with persistent inflammation of vessel wall and delayed endothelial healing that may increase the risk of late and very late stent thrombosis. This study sought to evaluate the efficacy and safety of HELIOS completed biodegradable polymer sirolimus-eluting stent (SES) in de novo coronary lesions.

METHODSTotally, 287 patients with one or two de novo coronary lesions (lesion length ≤ 38 mm and reference vessel diameter 2.5-4.0 mm) were enrolled in the HOPE study, a prospective, multicenter, randomized, non-inferiority trial. Patients were randomized to treatment either with HELIOS completed biodegradable polymer SES (n = 142) or PARTNER durable polymer SES (n = 145). The primary endpoint was angiographic in-stent late lumen loss (LLL) at 9-month follow-up. The secondary endpoint included stent thrombosis and major adverse cardiac events including cardiac death, myocardial infarction (MI) and target lesion revascularization (TLR).

RESULTSThe 9-month in-stent LLL in the HELIOS group was similar to the PARTNER group, (0.16 ± 0.22) mm vs. (0.19 ± 0.30) mm (P = 0.28). The difference and 95% confidence interval were -0.03 (-0.09, 0.04), and the P value for non-inferiority <0.01. Major adverse cardiovascular event (MACE) occurred in 7.9% vs. 8.2%, MI in 2.4% vs. 3.0%, TLR in 5.5% vs. 3.0%, and stent thrombosis in 0 vs. 1.5%; and events were comparable between the HELIOS group and PARTNER group at three-year follow-up (all P > 0.05). The three-year cardiac death was lower in the HELIOS group, but with no significant difference, 0 vs. 3.0% (P = 0.12).

CONCLUSIONSIn the HOPE trial, the novel completed biodegradable polymer SES HELIOS was non-inferior to the durable polymer SES PARTNER with respect to nine-month in-stent LLL in de novo coronary lesions. The incidence of other clinical endpoints was low for both of the stents in three-year follow-up.

The cluster sampling method was used and a retrospective survey on mortality trends of cerebrovascular diseases from 1989 to 2008 was conducted among residents from Erqi District in Zhengzhou city and Xigong District in Luoyang city. The average mortality rate of cerebrovascular diseases in these two districts was 69. 5/100 000 in 1989 to 2008. The standardized mortality rate for men was 118. 67/100 000 in 1989 to 1993, and dropped to 44. 23/100 000 in 2004 to 2008. The standardized mortality rate for women was 68.21/100 000 in 1989 to 1993, and dropped to 30. 2/100 000 in 2004 to 2008. The declining trends of cerebrovascular disease mortality rates might be related to early diagnosis and early treatment of the disease, and the extensive health education and prevention programs.
