AlM: To investigate the refractive status of the preschool children in Xiantao, Hubei Province in order to find out the abnormal refraction error beyond the physiological range.
METHODS: ln this cross - sectional study, we investigated preschool children in kindergartens and the scattered ones were 12 716 ( 25 432 eyes ) ranging from 6mo ~ 6 years old. 1 581 children ( 3 162 eyes ) were diagnosed ametropia by Suresight refractive screening instrument, which were confirmed again after mydriasis optometry.
RESULTS: The incidence rate of ametropia in preschool children in Xiantao was 12. 4%, and statistics showed no significant difference between boys and girls (P>0. 05), but had differences of morbility rate among each age group (P<0. 05). With age increasing morbility rate of the refractive error decreased. The simple hyperopia and the compound hyperopia astigmatism were dominant in all refraction error. Professional ophthalmologists diagnosed amblyopia in 261 children (522 eyes), which was 16. 5%, among 1581 abnormal refractive children (3 162 eyes) screened out by Suresight refractive screening instrument.
CONCLUSlON: The incidence rate of ametropia decreases with age increasing in the preschool children from 6mo~6 years old, which imply preschool children should have mydriasis optometry in order to find out amblyopia and other congenital eye disease.

Objective To study the gender differences in echocardiography in essential hypertensives. Methods Echocardiography measurement was performed in 108 subjects with Grade 1-2 essential hypertension (52 in female patient group, PGf, and 56 in male patient group, PGm). Forty two normotensive subjects (20 in female control group, CGf, and 22 in male control group, CGm) were as controls.Data were obtained by averaging measurements of the traced heart chambers and velocity curves in 5 cardiac cycles. Results Compared with PGm, the following echocardiographic features in PGf were showed:LAID (37.24±5.88 vs 32.14±3.80)mm,P<0.01] and MVa[(84.18±12.13 vs 81.71±12.30)cm/s, P<0. 05] were greater; LVMI [ ( 119.26 ± 22.33 vs 128.17 ± 27.00 ) g/m2 , P<0. 05], EF ( 75.13 % ±6.69% vs 83.00% ±3.68%,P<0. 01), FS (41.67% ±7.99%0 vs 49.03% ± 7.35%, P<0.01), MVe[(68. 28±8.66 vs 73. 73±11.46)cm/s, P<0. 05] and MVe/a(0.83±0. 08 vs 0. 93±0.11, P<0.01)were lower. The differences between CGf and CGm were not significant. Conclusion There are echocardiographic differences between sexes in hypertensives including cardiac structural and functional changes. Hypertensive woman is more susceptible to both cardiac structure damage and cardiac dysfunction.

With the deepening of research in recent years, tumor metabolic reprogramming has gradually become the focus of research, and targeting tumor cell metabolism has also become a new means of tumor therapy. The metabolic process affects almost all the physiological processes of the organism, and lipid metabolism is an important part of the metabolic process. Studies have shown that changes in lipid uptake, storage and fatty acid synthesis and decomposition have occurred in a variety of tumors. Abnormal lipid metabolism will promote the rapid proliferation of tumors. Abnormal expression of a variety of key metabolic enzymes in the process of lipid metabolism is the key to tumor progression. The purpose of this paper is to explain the metabolic regulation of lipid metabolism and related metabolic enzymes in hematological tumors, and to provide ideas for the treatment of hematological tumors.

OBJECTIVETo approach the central nervous mechanism of abdominal acupuncture by using resting-state functional magnetic resonance imaging (fMRI).
METHODSTwelve old healthy volunteers were treated by standardized abdominal acupuncture with invigorating the kidney and nourishing marrow method and Zhongwan (CV 12), Xiawan (CV 10), Qihai (CV 6), Guanyuan (CV 4), Qixue (KI 13), Shangqu (KI 17) and Huaroumen (ST 24) were selected. They were examined by using resting-state fMRI before and after treatment of abdominal acupuncture and the brain functional connectivities were analyzed based on bilateral hippocampus chosen as seed points.
RESULTS(1) Before acupuncture, functional connectivities were found in the bilateral middle frontal gyrus, bilateral superior temporal gyrus, bilateral middle temporal gyrus, bilateral thalamus, bilateral subiculum hippocampi, bilateral insula, the cupula and declivis of right cerebellum, left superior frontal gyrus, left head of caudate nucleus, left posterior cingulate gyrus and left inferior parietal lobule (all P < 0.05). (2) After acupuncture, functional connectivities were found in the bilateral superior frontal gyrus, bilateral superior temporal gyrus, bilateral middle temporal gyrus, bilateral thalamus, bilateral insula, bilateral subiculum hippocampi, bilateral inferior parietal lobule, bilateral postcentral gyrus, bilateral cingulate gyrus, right head of caudate nucleus, right middle occipital gyrus and right posterior cingulate gyrus (all P < 0.05). (3) After acupuncture, there were intensity functional connectivities greater than before acupuncture in the bilateral superior frontal gyrus, bilateral middle frontal gyrus, bilateral superior temporal gyrus, bilateral superior parietal lobule, right inferior frontal gyrus, right anterior cingulate gyrus, right fusiform gyrus, right precuneus and right postcentral gyrus, while the intensity of functional connectivities of left middle temporal gyrus, right lingual gyrus, left cuneus/precuneus and left inferior parietal lobule were attenuated.
CONCLUSIONAbdominal acupuncture with invigorating the kidney and nourishing marrow method can improve the allomeric function of the brain cognition network of central nervous system.

Objective To study the expression of p73 in human non-small cell lung cancer (NSCLC) and the relationship between p73 expression and clinico-pathological parameters. Methods Expression of p7 3 gene was detected by RT-PCR in 32 human NSCLC tissues, tissues adjacent to ca ncer and non-cancer lung tissues. Results p73 gene expression up-regulated substantially and detected in 87.5%(28/32) of human NSCLC tissues while expressed at low level in tissues adjacent to cancer and non-cancer lung tissues. Conclusion Marked up-regulation of p73 gene expres sion is found in human NSCLC.

A series of novel sorafenib analogues were designed and synthesized. The cytotoxic activities of these compounds were tested in four tumor cell lines. Some of the compounds showed potent antiproliferative activity against the tested cell lines with IC50 = 4-20 micromol x L(-1). Some compounds demonstrated competitive antiproliferative activities to sorafenib against tested cancer cell lines. Among them, compound 7c demonstrated significant inhibitory activities on ACHN, HCT116 and MDA-MB-231 cell lines with IC50 values of 9.01, 4.97, 6.61 micromol x L(-1), respectively.

Poly(ADP-ribose) polymerase-1 (PARP-1) has emerged as a promising anticancer drug target due to its key role in the DNA repair process. It can polymerize ADP-ribose units on its substrate proteins which are involved in the regulation of DNA repair. In this work, a novel series of para-substituted 1-benzyl-quinazoline-2, 4 (1H, 3H)-diones was designed and synthesized, and the inhibitory activities against PARP-1 of compounds 7a-7e, 8a-8f, 9a-9c and 10a-10c were evaluated. Of all the tested compounds, nine compounds displayed inhibitory activities with IC50 values ranging from 4.6 to 39.2 micromol x L(-1). In order to predict the binding modes of the potent molecules, molecular docking was performed using CDOCKER algorithm, and that will facilitate to further develop more potent PARP-1 inhibitors with a quinazolinedione scaffold.
