Almost 3% of newborns are diagnosed as small for gestational age(SGA)worldwide.Born SGA is one of the important causes of perinatal morbidity and mortality,and is also associated with metabolic diseases in adulthood.Low birth weight by itself is insufficient to characterize growth restriction,as it does not include information about the neonate’s body proportionality.Depending on the origin,timing and severity of in-sult,small for gestational age infants are classified into two types:proportionate or symmetric growth restriction (SGR)and disproportionate or asymmetric growth restriction(AGR).There may be differences in physical and neurological development of these two types.This study compares three classification indexes,and to find differ-ences in postnatal growth of these two types.

Objective To understand the distribution of overweight and obesity in 0-5 years old children who were born small for gestational age ( SGA) in Shanghai through a cross-sectional investigation. Methods All resident children aged 0-5 years were included, covering all 18 districts in Shanghai. Health-check cards were prepared for SGA children. The check-up included weight,length/height and head circumference. Body mass index ( BMI) was used to evaluate the overweight and obesity according to the standard of World Health Organization ( WHO) . Results This study investigated 728 602 children aged 0-5 years in Shanghai,and ultimately 23 871 of them were defined as SGA,a-mong whom 9 805(41. 4%) were boys and 14 066(58. 9%) were girls. The BMI of SGA children were higher than that of appropriate for gestational age( AGA) from 4 to 18 months,while for the rest of the time,they were basically the same. There was no difference in changing tendency of BMI between SGA children and those AGA children. The distri-bution of overweight and obesity according to the standard of WHO in SGA boys among different ages was 7. 7% to 20. 7%, and 15. 7% in average;the distribution of SGA girls among different ages was 5. 9% to 18. 3%,and 12. 9% in average. The proportion of overweight at the age of 4-18 months was significantly higher than that of other ages. There was no correlation between overweight at 0-2 years old and overweight at the age of 5(P>0. 05). Conclusions Com-pared with SGA girls,overweight and obesity in SGA boys were more serious. The age of 4-18 months were the period of high incidence of overweight. There was no correlation between overweight at 0-2 years old and overweight at the age of 5.

BACKGROUND: It is significant to establish a kind of effective, conve nient and reliable animal model of hypertension. At present, dogs, rats and rabbits are usually used to establish hypertensive models at home and abroad, and the renal artery stenosis induced hypertensive models are ex tensively used to research hypertension and its complication for human be ings because they are convenient and reliable, and there are many methods to establish them, but the effects are to be evaluated. OBJECTIVE: To establish convenient and reliable animal models of ex perimental renal artery stenosis induced hypertension. DESIGN: A randomized grouping design and animal experiment. SETTING: Institute of Cerebrovascular diseases, Medical College Hospital of Qingdao University. MATERIALS: The experiments were carried out in Shandong Key Labora tory for Prevention and treatment of Brain Disease from September 2005 to February 2006. Eighty-one healthy Wistar rats divided into 7 groups accord ing to the method of random number table: unilateral renal artery stenosis group (n=18), bilateral renal artery stenosis group (n=17), unilateral renal artery ligation group (n=15), bilateral renal artery ligation group (n=15), uni lateral renal artery stenosis sham-operated group (n=6), bilateral renal artery stenosis sham-operated group (n=4) and normal control group (n=6). METHODS: Unilateral renal artery stenosis group: Right renal artery was clamped with miniature silver clip, and left kidney was resected after 12 days. Bilateral renal artery stenosis group: Right renal artery was clamped with miniature silver clip, and the same treatment was given to the left side after 12 days. Unilateral renal artery ligation group: Right renal artery was ligated with filament, and left kidney was resected after 12 days. Bilateral renal artery ligation group: Right renal artery was ligated with filament, and the same treatment was given to the left side after 12 days. Unilateral renal artery stenosis sham-operated group: Right kidney was exposed, and returned to the original place without any treatment, and left kidney was resected af ter 12 days. Bilateral renal artery stenosis sham-operated group: Right kid ney was exposed, and returned to the original place without any treatment, and the same treatment was given to the left side after 12 days. Normal con trol group: The rats were not given any treatment. The blood pressure and heart rate were determined with RBP-2 hemomanometer for rats. MAIN OUTCOME MEASURES: The successful rate of model estab lishment, blood pressure and heart rate were observed. RESULTS: Totally 81 rats were used, and 61 of them died, all were in volved in the analysis of results without deletion. ① Blood pressures in the unilateral and bilateral renal artery stenosis groups and bilateral renal artery ligation group were obviously higher than those in the normal control group and bilateral renal artery stenosis sham-operated group [(138.0 ±36.5), (154.2±11.6), (160.5±0.7), (101.3±17.6), (108.3±5.7) mm Hg]. ② The changes of heart rate in the renal artery stenosis group were unstable, and the heart rates in the unilateral and bilateral renal artery stenosis groups, bilateral renal artery ligation group, normal control group and bilat eral renal artery stenosis sham-operated group were (367.5±47.2), (420.2 ±47.8), (386.0±4.2), (390.3±42.4), (417.3±27.5) beats per minute, respec tively. ③ The survival rates in the renal artery stenosis groups (22%, 29%) were significantly higher than those in the renal artery ligation groups (0,12%), and it was the highest in the unilateral renal artery stenosis group.CONCLUSION: The method of clamping bilateral renal arteries can establish stable rat models of hypertension induced by renal artery stenosis.

OBJECTIVE:To study the influential factors related to efficacy of Peach kernel-Rheum palmatum couplet medi-cines in TCM formula,and to reveal the general regularity of compatibility environment,common ratio,processing variety and dosage forms of P. kernel-R. palmatum couplet medicines. METHODS:Using Chinese Medical Prescription Selected Dictionary ed-ited by Peng Huairen as data source,142 formulas of P. kernel-R. palmatum couplet medicines were collected. By establishing data-base,compatibility types of P. kernel-R. palmatum couplet medicines,as well as common ratio,processed prodact,dosage form were classified statistically. The influential factors related to efficacy of P. kernel-R. palmatum couplet medicines with different pro-portions were summarized. RESULTS:The efficacy of P. kernel-R. palmatum couplet medicines could be divided into 6 aspects and 11 roles,including activating blood circulation to dissipate blood stasis(activating blood to relieve pain,promoting blood circula-tion to eliminate disease,activating blood to promote menstruation,breaking stagnant and eliminating blood stasis),eliminating carbuncle and detoxicating(cleaning intestine and clearing away the pathogenic heat of lung,eliminating carbuncle and expelling pus,eliminating sore and detoxicating),expelling the pathogenic heat to loosen the bowels,warming yang for dispelling cold,forti-fying the spleen and nourishing the stomach,relaxing tendon and activating blood. The compatibility environment of P. kernel-R. pal-matum couplet medicines were mainly compatible with TCM for activating qi to eliminate stasis,activating blood to promote menstru-ation,breaking stagnant and eliminating blood stasis,expelling the pathogenic heat to expel stasis. The ratio of P. kernel to R. palma-tum ranged 1 : 8-4 : 1,and the ratio ranged 1 : 8-3 : 1 when performing the role of actirating blood circalation to dissipate blood stasis. Common processed products were crude P. kernel and prepared R. palmatum. Common dosage forms were mainly decoction,pill and powder. CONCLUSIONS:Compatibility environment,ratio,processing varieties,dosage forms influence the effects of P. kernel-R. palmatum couplet medicines,especially compatibility environment.
