70% to 80% of people with diabetes died from cardiovascular complications, which had become the leading cause of death in diabetic patients. Cardiovascular complications in diabetic patients are mainly associated with vascular endothelial dysfunction and poor neovascularization. Its important influencing factors are changes in the number of endothelial progenitor cells and dysfunction. Hyperglycemia in diabetic patients can cause endothelial progenitor cell dysfunction, inhibit its proliferation ability, angiogenesis ability and paracrine effect. In order to provide research ideas for the prevention and treatment of cardiovascular complications in diabetic patients, this article aims to review the relevant mechanism of the effect of hyperglycemia on the number and function of endothelial progenitor cells in patients with diabetes, and the application of endothelial progenitor cells in the treatment of diabetic cardiovascular disease.

OBJECTIVETo describe the prevalence of body overweight and obesity and its changes among Chinese people during 1992-2002, and to provide scientific basis for developing intervention strategies for obesity in China.

METHODSThe data from "1992 China third National Nutrition Survey" (78,704 subjects, 38,323 male and 40,381 female) and from "2002 China National Nutrition and Health Survey" (209,849 subjects, 101,377 male and 108,472 female) were used in this study. The overweight and obesity were defined by using WHO Z-score criteria for children younger than 7 years old, Chinese age-, sex-specific BMI criteria for children aged 7-17 years, and Chinese BMI criteria for adults.

RESULTSThe overall prevalence of overweight and obesity of Chinese people was increased by 38.6% and 80.6%, respectively during the period of 1992-2002. The prevalence of overweight and obesity of Chinese people aged 0-6 years, 7-17 years, 18-44 years, 45-59 years and above 60 years was increased 31.7%, 17.9%, 66.7%, 45.2% and 43.7%, respectively. The increase of the prevalence of overweight and obesity was higher in girls younger than 6 years than their male counterparts, while among other age groups, that were higher in boys than girls. The prevalence of overweight and obesity among people living in rural areas was lower than that of their urban counterparts, while the increment of overweight and obesity prevalence among rural people was greater than that of their urban counterparts. It was estimated that another 70 million overweight and 30 million obese Chinese people emerged in China from 1992 to 2002.

CONCLUSIONThe prevalence of overweight and obesity of Chinese people was increased rapidly in the past decade, which had affected 260 million Chinese people. It would continue to increase in the near future if effective intervention measures have not been taken.

OBJECTIVETo compare the enhanced recovery program after surgery (ERAS) with conventional perioperative management in patients undergoing radical resection for colorectal cancer.

METHODSThe ERAS protocol included a combination of evidence-based and consensus methodology. A total of 597 consecutive patients undergoing elective colorectal resection were randomized to either the ERAS(n=299) or the control group(n=298). Outcomes related to nutrition and metabolism index, stress index, and recovery index were measured and recorded.

RESULTSDemographics and operative parameters were similar between the two groups(P>0.05). The nutritional status of patients in the ERAS group was improved after surgery compared with that of the control group. On postoperative day (POD) 1, the HOMA-IR in the ERAS group was significantly lower than that in the control group(P<0.01). The cortisol level in the control group was elevated on both POD 1(P<0.01) and POD 5(P<0.01) compared to the preoperative level. However, the cortisol level was not increased until POD 5(P<0.01) in the ERAS group. The levels of TNF-α, IL-1β, IL-6, and IFN-γ were reduced in the ERAS group, indicating less postoperative stress responses compared with the control group. In addition, ERAS group was associated with accelerated recovery of gastrointestinal function. The postoperative length of stay [(5.7±1.6) d vs. (6.6±2.4) d, P<0.01] and expense[(15 998±2655) RMB vs. (17 763±3059) RMB, P<0.01] were reduced in the ERAS group. Twenty-eight patients(9.4%) in the control group and 29(9.7%) in the ERAS group developed complications, while the difference was not statistically significant(P>0.05).

CONCLUSIONERAS protocol alleviates surgical stress response and accelerates postoperative recovery without compromising patient safety.

OBJECTIVETo explore distribution of the Liver and Lung Channels in the brain so as to provide imaging basis for construction of channel theory in the brain.

METHODSSixty healthy student volunteers were randomly divided into a Liver Channel group (I) and a Lung Channel group (II), and the each group was further divided into five subgroups with 6 volunteers in each subgroup, based on five-shu-point principles which, were Dadun (LR 1, I 1), Xingjian (LR 2, I 2), Taichong (LR 3, I 3), Zhongfeng (LR 4, I 4), Ququan (LR 8, I 5), Shaoshang (LU 11, II 1), Yuji (LU 10, II 2), Taiyuan (LU 9, II 3), Jingqu (LU 8, II 4), and Chize (LU 5, II 5), respectively. In order to observe the brain activating patterns during acupuncture at the different acupoints, functional magnetic resonance imaging (fMRI) technique was adopted. All image data were then analyzed with SPM 2 software. The statistical parameter gram was composed of the pixel P < 0.01, and anatomic location was made according to Talairach coordinate, attaining experimentally activated areas, and the commonly activated area of five-shu-point of each channel was considered as the brain distribution of the Liver and Lung Channels.

RESULTSThe common areas activated by the five-shu-points of the Liver Channel were homolateral Brodmann area (BA) 34, BA 47, red nucleus, contralateral BA 19, BA 30, BA 39, the superior parietal lobule, cerebellum decline, and bilateral BA 3 and culmen. The common areas activated by the five-shu-points of the Lung Channels included homolateral BA 2, BA 18, BA 35, and contralateral BA 9 and substania nigra.

CONCLUSIONThere are relatively specific corresponding brain areas for the Liver and Lung Channels, indicating that there is possible relatively specific connection between channels and the brain.
