Objective:To study the different feeding practices of Chinese infants within four months of age in 2002. Method:The method of multi-steps cluster sampling was adopted. In order to ensure the sample size sufficient additional subjects were included in this survey. Results:More than two thirds (71.6%) of infants within four months of age had been almost exclusively breastfed, 65.5% and 74.4% in urban and rural areas respectively. The average percentage of mixed feeding was 23.0% (27.0% in urban and 21.2% in rural areas); and that of artificial feeding was 5.4% (7.5% in urban and 4.4% in rural areas). The rate of breastfeeding decreased with the increase of family income. Conclusion:Although the rate of almost exclusive breastfeeding is increasing, there is still far away from the aim of 85% in 2001-2010 National Outline for Children.

The article introduces the concept of stigma and the measurement tools of stigma in abortion women as well as research progress of sociological factors, quality of life and interventions of abortion women. This article points out that china is still lack of related research. Strengthening the care for artificial abortion women from people of all walks of life is called on.

OBJECTIVETo study the relationship between milk intake of 3 - 6 years old preschool children and their growth.

METHODSThe data bank of 2002 China National and Health Survey were used to analyze the relationship of milk consumption and the growth of children aged 3 - 6 in urban and rural areas.

RESULTSThe percentages of the diet with milk in urban and rural areas were 46.9% and 8.2% respectively, there was significant difference between the urban and rural areas. The averaged milk intake of preschool children were 23.8 g/d, the milk intake of urban children was significantly higher than that in the rural areas (P < 0.01). The height and weight of children with milk or its products in their diets in the group aged 4, 5 and 6 years were significantly higher than those of children without milk or its products in their diets (P < 0.05).

CONCLUSIONThere was close relationship between milk intake of children 3 - 6 years old and their growth, the volume of milk intake of preschool children should be improved in urban and rural areas.

OBJECTIVETo study the relationship between the hemoglobin level of children < or = 3 years and anemia of their mothers.

METHODSMulti-steps cluster sampling was adopted. In order to ensure sufficient number of babies and young children and postpartum in this survey, additional subjects were included in the sample. The subjects in study were collected in the same family.

RESULTSThe average anemia prevalence of children < or = 3 years was significant different between urban and rural (26.9%, 94/350 and 32.4%, 594/1835, P < 0.05) areas. The birth weight of anemia children < or = 3 years was significant lower than nonanemic children (P < 0.05); the incidence of low birth weight of anemia children < or = 3 years was significant higher than nonanemic children (P < 0.05); the percentage of Hb < 100 g/L and < 110 g/L were 7.6% (166/2185) and 24.9% (544/2185); the Hb levels of children fed by anemia mother and nonanemic mother were significantly different (115.6 +/- 17.4) g/L, (115.2 +/- 16.7) g/L and (123.3 +/- 14.9) g/L, (122.2 +/- 15.3) g/L, P < 0.001.

CONCLUSIONThere should be significant relation between the Hb level of children < or = 3 years and anemia of their mother.

Objective:To examine the correlation between serum Klotho levels and frailty in elderly people.Methods:In this cross-sectional study, 150 community-dwelling elderly people aged 65 years and over were enrolled.Subjects were divided into a frail(n=50, 33.3%), a pre-frail(n=47, 31.3%)and a non-frail(n=53, 35.3%)group based on the Fried phenotype.General participant data, routine laboratory test results, short physical performance battery(SPPB)results and human body composition data were collected.Serum Klotho protein levels were measured by an enzyme-linked immunosorbent assay.The relationship between serum Klotho protein levels and frailty was analyzed by using Spearmen's correlation analysis and Logistic regression analysis.Results:Klotho protein levels were lower in the frail group than in the non-frail group( P=0.001), whereas differences between the frail group and the pre-frail group and between the pre-frail group and the non-frail group were not statistically significant(all P>0.05).When Klotho protein levels were classified into four quartiles, i.e., Q 1, Q 2, Q 3, and Q 4, using three cut-off vales(2.28, 3.52, and 5.09 mg/L), the prevalences of frailty were 51.4%(19/37), 39.5%(15/38), 24.3%(9/37)and 18.4%(7/38), respectively.The prevalence of frailty decreased with increasing Klotho protein levels( χ2=11.204, P=0.011).Spearman correlation analysis showed that the Klotho protein level was negatively correlated with frailty( r=-0.310, P<0.001).Multivariate Logistic regression analysis results showed that age( OR=1.109, 95% CI: 1.011-1.217, P=0.028)and sarcopenia( OR=6.511, 95% CI: 1.279-33.147, P=0.024)were risk factors for frailty, while walking( OR=0.104, 95% CI: 0.033-0.326, P<0.001), a high SPPB score( OR=0.780, 95% CI: 0.627-0.970, P=0.026), and a high Klotho protein level( OR=0.752, 95% CI: 0.581-0.974, P=0.031)were protective factors against frailty. Conclusions:The serum Klotho protein level may be used as a parameter for the assessment of frailty.It is negatively correlated with frailty, suggesting that elderly people with low serum Klotho protein levels are at high risk of developing frailty.

Objective:To evaluate the efficacy and safety of antaitasvir phosphate 100 mg or 200 mg combined with yiqibuvir for 12 weeks in patients with various genotypes of chronic hepatitis C, without cirrhosis or compensated stage cirrhosis.Methods:Patients with chronic hepatitis C (without cirrhosis or compensated stage cirrhosis) were randomly assigned to the antaitasvir phosphate 100 mg+yiqibuvir 600 mg group (100 mg group) or the antaitasvir phosphate 200 mg+yiqibuvir 600 mg group (200 mg group) in a 1∶1 ratio. The drugs were continuously administered once a day for 12 weeks and observed for 24 weeks after drug withdrawal. The drug safety profile was assessed concurrently with the observation of the sustained virological response (SVR12) in the two patient groups 12 weeks following the drug cessation. The intention-to-treat concept was used to define as closely as possible a full analysis set, including all randomized cases who received the experimental drug at least once. The safety set was collected from all subjects who received the experimental drug at least once (regardless of whether they participated in the randomization group) in this study. All efficacy endpoints and safety profile data were summarized using descriptive statistics. The primary efficacy endpoint was SVR12. The primary analysis was performed on a full analysis set. The frequency and proportion of cases were calculated in the experimental drug group (antaitasvir phosphate capsules combined with yiqibuvir tablets) that achieved "HCV RNA
