Objective There is little population-based data on the prevalence and the environmental or genetic determinants of left ventricular hypertrophy (LVH) in China. The purpose of this paper is to study LVH in relation to systolic blood pressure and the angiotensin converting enzyme (ACE) insertion/deletion(I/D) polymorphism in Chinese. Methods We recorded 12-lead ECG (CardioSoft, v4.2) in 1365 residents in the Jingning County, Zhejiang Province, China. LVH was defined according to the gender-specific Sokolow-Lyon and Comell product ECG criteria. Results Regardless of whether the Sokolow-Lyon or Comell product ECG criteria was used, the prevalence of LVH (20.7% and 4.8%, respectively) significantly (P<0.0001) increased with male gender (odds ratio [OR] 2.33 and 7.15) and systolic blood pressure (per 10 mm Hg increase, OR 1.46 and 1.33). If the Sokolow-Lyon criteria was used, the prevalence of LVH was also influenced by alcohol intake (OR 1.44, P=0.03) and body mass index (OR 0.83, P=0.0005). The association between the Sokolow-Lyon voltage amplitude and the ACE I/D polymorphism was dependent on antihypertensive therapy (P=0.01). In 1262 untreated subjects, but not 103 patients on antihypertensive medication, the ACE DD compared with Ⅱ subjects had significantly higher Sokolow-Lyon voltage amplitudes (29.8±0.6 vs. 28.0±20.5 mV, P=0.02) and higher risk of LVH (OR 1.74, 95% CI: 1. 12-2.69, P=0.01). Conclusion LVH is prevalent in Chinese, and is associated with systolic blood pressure and the ACE D allele. The genetic association might be modulated by antihypertensive therapy.

Acta Physiologica Sinica 2012;64(3):341-345
The AMP-activated protein kinase (AMPK) is a pivotal serine/threonine kinase participating in the regulation of glucose, lipid as well as protein metabolism and maintenance of energy homeostasis. Recent studies demonstrated that AMPK can also inhibit nuclear factor-κB, suppress the expression of inflammatory genes and attenuate inflammatory injury through phosphorylating its downstream targets including SIRT1, PGC-lα, p53 and FoxO3a. In addition, the widely used antidiabetic metformin also exerts its anti-inflammatory effects through activating AMPK. Therefore, AMPK is emerging as a promising novel target for the development of anti-inflammatory drugs. This review summarized the anti-inflammatory effects of AMPK and the underling molecular mechanisms.

· AIM :To investigate the role of pericytes in growth of retinal microvascular endothelial cells with a co-culture system in order to understand some mechanism of angiogenesis in hypoxia induced retinal neovascular disorders.(RMECs) were isolated by a modified protocol using CD31 coated Dynabeads, and identified by immunocytochemical staining with anti-Factor Ⅷ and CD31 antibodies. Rat retinal pericytes were isolated and characterized by immunofluorescent staining with PDGFR-β; and desmin antibodies. Pericytes and RMECs were cultured in a contact co-culture system both under normoxia and hypoxia by Millicell chamber. RMECs proliferation was evaluated by MTT and cell cycle assay with flow cytometry. RT-PCR was used to detect the alteration of KDR/Flk-1 mRNA level in RMECs under normoxia or hypoxia in the co-culture system.harvested with the modified isolating method. The two cell types were identified by positive Factor Ⅷ, CD31 and PDGFR-β, desmin cytochemical staining respectively.RMECs proliferated significantly under hypoxia from 3 to 9d with a maximal rate on day 6 (24.9%, P < 0.01) by MTT. In the co-culture system, the proliferation of RMECs was inhibited by pericytes. After 6d exposure to hypoxia,the fraction of S-phase RMECs number was greatly increased by 43.9% (P < 0.01). In the co-culture system,RMECs proliferation was inhibited by pericytes through decreasing the fraction of S-phase cell number both under normoxia (3.6%, P<0.05) and under hypoxia (15.1%,P<0.01). KDR/Flk-1 mRNA level in single cultured RMECs was shown to increase approximately 1.3-fold when exposed to hypoxia. Compared with single cultured RMECs, co-culture with pericytes could decrease KDR/Flk-1 mRNA by 45.1% (P<0.05) and 27.7% (P < 0.05) under normoxia and hypoxia condition respectively.pericytes could inhibit proliferation of RMECs under both normoxia and hypoxia. The inhibition effects of pericytes maybe, at least in part, due to downregulation of KDR/Flk-1 of RMECs. These findings confirm that pericytes could be a potential inhibitor in the pathogenesis of retinal neovascularization.

AIMTo explore the effect of acute intra-peritoneal infection on leptin expression levels in peripheral blood and vital organs, and find out the role leptin plays in acute inflammation.
METHODSA cecal ligation and perforation model of rats was established, setting groups of sham-operation, intralipid injection, injury, estradiol injection and insulin injection. A rat leptin radioimmunoassay was used to check serum leptin concentrations at 12 h after the injury, and RT-PCR was also used to detect leptin mRNA expressions in adipose tissue, lung and liver.
RESULTSCompared with serum leptin level of sham-operation group after injury, that of all the other four groups showed no significant difference, while the level of intralipid group was significantly higher than that of injury group and estradiol group. Compared with leptin mRNA expression level of sham-operation group after injury, that of the other four groups had different changes. Leptin mRNA expression of intralipid group was significantly increased in adipose tissue but decreased in lung and liver.
CONCLUSIONLeptin expression levels may be affected by the changes of energy metabolism and neuroendocrine function after injury, which suggests a possible protective role for leptin in the recovery of body homeostasis.

To investigate the suitable site environment for Atractylodes lancea, field trials in different niches was carried out, and the seedling growth, biomass and volatile oil components in different microhabitas was studied. The study found that the survival rate, plant height, volatile oil content of those which growing under the bamboo were significantly higher than those exposed in the open field. The survival rate understory was (76 ± 15.1) %, plant height understory was (77 ± 14. 8) cm and the summation of the four kinds of volatile oil content understory reached up to 4.09%; The same evaluation values of these indicators of the four faces in the open field respectively: survival rate is 30%, plant height was (77 ± 14.8) cm and the summation of the four kinds of volatile oil content was 2.24%. But, the yield of the understory (41 ± 22.3) g was significantly lower than those four faces in the open field (104.5 g) on the contrary. For the four open field towards, the yield of the east facing, which organic matter and other nutritional conditions were better than others, was significantly higher than those in the other facings. A. lancea was found to be an anti-poor and shading-like or growing in east facing slope herb through the correlation analysis of light, temperature, soil and leaf nutrients with seedling growth, biomass and volatile oil components. It also reminds us that the understory herb with high survival rate, low incidence, low management costs, and high medicinal ingredients, although it's production is not so high, but it can be improved by increased organic fertilizer. So the ecological planting patterns which can intercropping herbs with the forest was proposed.
