ABSTRACT
Objective To investigate the prevalence and trend of Helicobacter pylori (HP) infection in children with gastrointestinal symptoms in Kunming area, and to provide basis for prevention and cure. Methods All of 12 932 cases with gastrointestinal symptoms were adopted by retrospective analysis method from January 2013 to December 2016, and HP infection was detected by 13C-urea breath test (13C-UBT). The epidemioloqical characteristics of children with HP infection in including prevalence trend and gender and age HP were statistically analyzed. Results The rates of HP from January 2013 to December 2016 were respectively 17.85%, 18.26%, 20.41% and 32.93%.The rate of HP positive was 24.08%(3 114/12 932), which was 24.82%(1 706/6 874) in boys and 23.24%(1 408/6 058) in girls. The rate of HP infection was significantly higher in boys than that in girls, and there was statistical differences (P＜0.05). The rate of HP infection showed a gradual upward trend with age. There was statistical differences in gender between age 11 and 14[(29.03% (349/1 202) vs. 22.62% (190/840)] (P＜0.05). Conclusions HP infection rate is high in the children with gastrointestinal symptoms in Kunming, and the rate of HP infection in children is related with gender .The rate of HP infection is significantly higher in boys than that in girls, and the positive rate is directly proportional.
ABSTRACT
Epigenetic regulation plays an important role in breast cancer research.The epigenetic modification of histone mainly affects the occurrence and development of breast cancer by adding and removing methyl,acetyl and phosphate groups under the action of various enzymes.Because of its reversible regulatory process,it can provide advantage for the affected region to return to the normal genome state.Clinically,this can be used to develop a variety of drugs for patient diagnosis and treatment and to provide treatment targets.
ABSTRACT
Objective To investigate the change of plasma vitamin D, A and E levels in infant with infantile hepatitis syndrome (IHS) and to provide reliable basis for clinical treatment. Methods Seventy-three infant with IHS (IHS group) from January 2015 to May 2016 and 82 cases of physical examination infant (control group) were enrolled in this study.The levels of plasma vitamin D, A and E were tested and compared between two groups. Results The levels of vitamin D, A and E in IHS group were significantly lower than those in control group:(37.871 ± 20.111) nmol/L vs. (97.708 ± 28.827) nmol/L, (1.082 ± 0.657)μmol/L vs. (1.810 ± 0.517)μmol/L, (21.252 ± 7.596)μmol/L vs. (26.647 ± 6.495)μmol/L, P<0.01 or <0.05. The nutritional status of vitamin D, A and E in two groups had significant differences (P<0.01). Conclusions There have obvious deficiency in fat-soluble vitamin D, A and E in infant with HIS , and vitamin D deficiency is the most obvious. The levels of vitamin D, A and E are the dynamic monitoring indicators of treatment, nutritional status evaluation and long-term complications development.
