Objective To investigate the prevalence and risk factors of metabolic obesity with normal weight (MON W) in Han nationality adult population,and to identify the cut-off points of body fat percentage (％ BF) by dualenergy X-ray absorptiometry(DXA) for defining MONW.Methods Six hundred and sixty subjects (403 men and 257 women) with body mass index(BMI) ranged from 18.5 to 23.9 kg/m2 were recruited into this study.Waist circumference(WC),blood pressure (BP),BM1,and ％ BF were measured.Serum concentrations of glucose,triglycerides(TG),total cholesterol (TC),high-density lipoprotein-cholesterol (HDL-C),low-density lipoproteincholesterol(LDL-C),serum insulin,and high-sensitivity C-reactive protein (hsCRP) were tested.Those within the highest quartile in the homeostasis model assessment of insulin resistance (HOMA-IR) with a normal BM1 between 18.5 and 23.9 kg/m2 were classified as MONW.Results The prevalence of MONW was 11.34％ for men and 16.34％ for women amongst normal-weight subjects,there was no significant different between men and women in the prevalence(P＞0.05).Multivariable Logistic regression analysis showed that TG(OR =5.92,P=0.001),LDLC (OR =13.65,P =0.009),hsCRP (OR =2.09,P =0.011),WC (OR =2.35,P ＜ 0.01),％ BF (total,OR =3.65,P＜0.01) and ％ BF(abdominal,OR =26.07,P＜0.01) were the risk factors of MONW amongst men.For women,TG (OR =9.12,P＜0.01),LDL-C (OR =2.64,P =0.005),HDL-C (OR =0.020,P＜ 0.01),hsCRP (OR =2.15,P =0.039),WC (OR =1.32,P =0.045),％ BF(total,OR =1.73,P＜0.01) and ％ BF(abdominal,OR =8.43,P＜0.01) were the risk factors of MONW.The cut-off points of ％ BF for diagnosing MONW by ROC were ％ BF≥25％ for men,％ BF ≥35.0％ for women.Conclusion MONW is quite common in Han nationality adult population;.％ BF,WC,hsCRP and lipid profiles were independently associated with MONW ％ BF ≥25 ％ for men,％ BF≥35.0％ for women can be used as reference cut-off.point for diagnosing MONW.

The tapeworm Taenia solium is an important human zoonotic parasite that causes great economic loss and also endangers public health. At present, an effective vaccine that will prevent infection and chemotherapy without any side effect remains to be developed. In this study, codon usage patterns in the T. solium genome were examined through 8,484 protein-coding genes. Neutrality analysis showed that T. solium had a narrow GC distribution, and a significant correlation was observed between GC12 and GC3. Examination of an NC (ENC vs GC3s)-plot showed a few genes on or close to the expected curve, but the majority of points with low-ENC (the effective number of codons) values were detected below the expected curve, suggesting that mutational bias plays a major role in shaping codon usage. The Parity Rule 2 plot (PR2) analysis showed that GC and AT were not used proportionally. We also identified 26 optimal codons in the T. solium genome, all of which ended with either a G or C residue. These optimal codons in the T. solium genome are likely consistent with tRNAs that are highly expressed in the cell, suggesting that mutational and translational selection forces are probably driving factors of codon usage bias in the T. solium genome.
