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.

OBJECTIVETo study topiramate's new functions according to the medicinal property combinations, in order to apply the traditional Chinese medicinal theory in discovering new purposes of old drugs.

METHODAccording to New Traditional Chinese Medicinal Families--Chemical Traditional Chinese Medicines, the authors found out topiramate's property. Then based on the therapeutic principle of diabetes, hypertension, epilepsy and lung cancer, as well as the relations of efficacies and medicinal property combinations, they summarized the corresponding medicinal property combination modes, compared topiramate's medicinal property combination mode with corresponding medicinal property combination modes of these diseases, and predict topiramate's new functions.

· 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.

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.

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.

Objective To improve the level of early detection and treatment of pyonephrosis. Methods This study included 41 cases(17 men and 24 women;mean age,49 years)of pyonephrosis.A variety of examinations,including urinary analysis,blood analysis,kidney nuclear medicine scan,ultrasonog- raphy,intravenous urography(IVU),and CT were used for the early diagnosis of pyonephrosis.Pereutaneous nephrostomy(PCN)drainage was done for the interim management of pyonephrosis,then phase 2 operation was performed in 28 cases.The double-J tube was placed in ureter by ureteroscope for drainage,and then phase 2 operation was done in 2 cases.Emergency operation was done in 10 cases.The remaining 1 case un- derwent ESWL after anti-infective therapy.Results Definite diagnosis of pyonephrosis before operation was made by invasive examinations in 31 cases(75.6%),and by percutaneous drainage in 4 cases;the other 6 cases were detected during operation.Only 6 cases(14.6%)underwent nephrectomy;the other 35 cases (85.4%)underwent kidney-sparing operation.Follow-up of 3 months to 9 years was available in 37 cases. No nephrectomy was needed in 33 cases with spared kidney.Serum creatinine was normal in the 4 cases un- dergoing nephrectomy.Conclusions The key to the treatment of pyonephrosis by kidney-sparing surgery is early diagnosis,timely drainage and relief of obstruction.Ultrasonography plays an important role in the early diagnosis of pyonephrosis,and CT has a high sensibility in the diagnosis.Pereutaneons nephrolithotomy (PCNL)secondary to drainage through pereutaneous nephrostomy was beneficial to the patients with kidney stones or upper ureter stones.
