The paper describes the basis, scope, and contents of the index system for assessing maternity and child care institutions in Beijing. The new system, based on the readjustment, recombination and redistribution of the original index system for assessment, has two newly added elements, viz. financial position analysis and leadership style and organization culture. In order to make a distinction between leaders' responsibilities and an institution's orientations and to reduce behavior abnormality and information bias in the process of assessment, the new system has been divided into two major parts: evaluation of the institution's conditions for survival and capabilities for development, which is jointly decided by internal and external factors, and appraisal of the institution's performance, which is decided mainly by internal factors.

Aim To establish two new rat models of visceral hypersensitivity in IBS by two chemical irritants.Methods Acetic acid or mustard was infused for six days in intestines of adult rats.After modeling,the rectal distention was performed and the thresholds of abdominal withdrawal reflex were measured.The frequency,peak value,peak-nadir value and area of the gastric and enteric electrical activity were recorded.And the contents of 5-HT in the blood serum were detected.Results Compared with the control group,the colon and rectum's sensitivity(P<0.05)and the frequency(P<0.01) of the acetic acid model were heightened.Meanwhile,the colon and rectum's sensitivity(P<0.01),the frequency(P<0.01),peak value(P<0.05),peak-nadir value(P<0.01)and area(P<0.01),and the contents of 5-HT(P<0.05)in serum of the mustard model were all changed,which indicated the increasing of sensitivity of the model.The colon and rectum's sensitivity,the gastric and enteric electrical activity and the contents of 5-HT in serum of the proving group were recovered to some extent.Conclusion The new rat model of visceral hypersensitivity in IBS is successfully set up by stimulating the intestines of adult rats with chemical substances.

OBJECTIVE:To investigate the protective effect of the compatibilities of ginsenosides Rg1 and aconitine on myocar-dial cell of in vitro cultured heart failure model. METHODS:The myocardial cells of neonate rat were grouped into normal control group,model group,positive control group(Deslanoside injection,1×10-7 mol/L),ginsenosides Rg1 group(1×10-8 mol/L),acon-itine group (1 × 10-9 mol/L) or their compatibilities groups (1∶1,2∶1,1∶2,V/V). Except for normal control group,other groups were given 0.8%pentobarbital sodium to induce heart failure model of myocardial cells. After modeling,each group was given rele-vant medicine for 1 h,and then the activities of T-ATPase,Ca2+-Mg2+-ATPase,Na+-K+-ATPase in cells were all detected. The activi-ties of acyl carrier protein(ACP)and lactate dehydrogenase(LDH),and the contents of brain natriuretic party(BNP),TNF-α and total glycogen were measured in cell culture fluid. RESULTS:Compared with normal control group, T-ATPase and Ca2+-Mg2+-ATPase activities were decreased significantly in model group;meanwhile,Na+-K+-ATPase activity was increased signifi-cantly,and ACP,LDH activities and BNP content in cell culture fluid were increased significantly(P<0.05). Compared with mod-el group,the activities of T-ATPase in treatment groups were increased significantly,while the activity of LDH in cell culture fluid was decreased significantly;when the volume ratio of ginsenoside Rg1 to aconitine was 2∶1,protective effect was the strongest;the activities of Na+-K+-ATPase in aconitine group and compatibility groups were all decreased significantly,with statistical signifi-cance(P<0.05). The activities of ACP and BNP in cell culture fluid were all decreased in treatment groups,but the content of to-tal glycogen in cells and the TNF-α content of in cell culture fluid had no change (P>0.05). CONCLUSIONS:Compatibility of ginsenosides Rg1 and aconitine can improve ATPase activities and membranous permeability,regulate BNP secretion and protect myocardial cell of heart failure model,especially the compatibility of ginsenosides Rg1 to aconitine of 2∶1 ratio.

Objective To investigate the characteristics of diet for infants in relatively poor counties in different cities of Yunnan and to provide a reference for carrying out educational consultation in the future by comparing and analyzing the data of infant diet in those areas.Methods Based on the GDP and habits of diet,the characteristics of infants' diet was investigated and analyzed in four counties including Yiliang in Zhaotong,Jianchuan in Dali,Lushui in Nujiang,and Mojiang in Puer,with low income and different habits of diet.Results No difference was found among people who fed the infants in terms of sex,age groups,feeding relationship and degree of education except for one fact that the feeding rate of parents in Jianchuan county was lower than that in Yiliang county.Based on the standard intake of nutrient in Chinese people,the intake of infant protein in 6-12 months achieved Chinese standard in four counties.Energy,fat and carbohydrates were lower than the standard (P＜O.05).Apart from the fact that energy,protein,fat and carbohydrates were lower in Yiliang county,no significant difference was found among four counties.The intake of protein and carbohydrates for infants in 13-24 months achieved Chinese standard in the four counties,but energy and fat were lower than the standard.The carbohydrates of infants in 6-24 months was normal and the fat was lower compared with acceptable macro nutrient distribution ranges.The intake of carbohydrates,fat and protein were similar among four counties.Conclusion The diet composition and the nutrient condition for infants are poor in four counties.Health education of nutrition for infants is needed in those areas.

This article was aimed to study the acute toxicities on intragastric administration of differentRadix Aconiti Lateralis Praeparataprocessed products to Beagle dogs. A total of 16 healthy and qualified Beagle dogs were randomly divided into the blank group,Pao-Fu-Pian(PFP) group,Pao-Tian-Xiong(PTX) group andHei-Shun-Pian(HSP) group according to the body weight. The intragastric administration of 4 g crude herb per kg was given. Before medication, 1 h, 24 h, and 3, 7, 14 days after medication, the body weight, food consumption, rectal temperature, electrocardiogram, blood routine and blood biochemistry were measured. The results showed that after medication, all dogs in three experimental groups were depressed. And there were significant differences in the electrolytes of blood. Among them, the HSP group was the most obvious one. The red blood cells, blood sugar and triglycerides of dogs in the PFP group had significant difference. The lymphocytes and blood sugar had significant difference of dogs in the PTX group. However, after the medication of HSP, the lymphocytes of the dogs were decreased significantly. It was concluded that the toxicity of three processed products followed the order of HSP > PFP > PTX.
