The polymorphism of insulin-like growth factor-I (IGF-I) in 13 pig breeds (total n=559) was detected by PCR-Hha I- RFLP, and allele A (151 bp and 28 bp) or allele B (116 bp, 35 bp and 28 bp) were observed. In these pig breeds, it was found that European pig breeds carried high frequencies of allele B, while Chinese native pig breeds carried high frequencies of allele A. Meanwhile the role of porcine IGF-I was investigated in 117 Nanchang White pigs and 360 Large Yorkshire pigs. Eight traits about growth and carcass were recorded for analyzing the associations between IGF-I gene polymorphism and performance quantitative traits. In the Nanchang White pigs, those with AA genotype generally had higher birth weight than those with AB genotype (p<0.05), but all these genotypes had no significant effect on the other traits which had been analyzed. In Large Yorkshire pigs, those with BB genotype had higher 2 months and 6 months body weight than those with AA genotype (p<0.05), and had a thicker hind-back-fat thickness and mid-back-thickness than those with AB and BB genotypes (p<0.05). And those with BB genotype were the thinnest in Large Yorkshire. Furthermore, pigs with AA genotype had a lower lean percentage than those with AB and BB genotypes (p<0.01), and the lean percentage of those with BB genotype was the highest. Based on these results, it is possible to make the IGF-I gene locus into the application of marker-assisted selection programmes.

Aims: NAFLD is generally correlated with the obesity epidemic. Asia is a heterogeneous region with varying socioeconomic levels and obesity prevalence; therefore, our goal was to esti mate the prevalence of NAFLD in Asia through a meta-analytic approach. Methods: PubMed and EMBASE databases were searched from 1989 to 2017 for relevant studies reporting NAFLD prev alence in Asia. All studies were reviewed by three independent investigators. We used random-effects models to provide point estimates with 95% confidence interval (CI) of prevalence. Pub lication bias was assessed by Egger weighted regression Meth ods. Results: From the 2700 titles and abstracts reviewed, 195 pa pers from 13 countries met the inclusion criteria and included 1,753,168 subjects. The overall pooled prevalence for NAFLD in Asia was 31% (95% CI: 29-32). Individual country prevalence was shown in Table 1. In countries with more than 3 studies, the lowest prevalence was seen in Japan (24%, 95% CI: 21-28) and the highest in Iran (36%, 95%CI 31-41). Notably, pooled prevalence from studies with sample <1,000 subjects was much higher (34%, 95% CI: 31-38, 45 studies, n=23,857) than esti mate from larger studies (≥1,000 subjects) (30%, 95% CI: 28- 31, 150 studies, n=172,9311). By sub-regions within Asia (Table 2), there was significant regional differences (P<0.01) with the highest NAFLD prevalence seen in West Asia (33%, 95% CI: 28-39, 13 studies, n=32,142) and the lowest in Southeast Asia (24%, 95% CI: 15-33, 5 studies, n=3457). By country income levels, NAFLD prevalence was 30% (95% CI: 29-32, 89 studies, n=1,005,409) for high-income countries and 31% (95% CI: 29-33, 106 studies, n=747,759) for middle-income countries (P<0.63). Conclusions: Overall NAFLD prevalence in Asia is 31% similar to Western countries and by country-income levels within Asia but varies by some sub-regions or Asia with the highest preva lence in West Asia (33%).
