Objective To investigate the relationship between β3 - adrenergic receptor(β3 - AR)gene poly-morphism and the susceptibility of occurrence in children obesity. Methods The database of PubMed,Web of Science,Springer Link,Medlink,SinoMed,Wanfang,VIP and CNKI were systematically browsed online. The study re-ports regarding β3 - AR associated with children obesity from January 1995 to February 2014 were included in the re-search. The data were extracted,evaluated and heterogeneity tested by using software RevMan 5. 1. Results A total of 162 related literature were retrieved,and 9 of them were eligible with 1 494 obese children and 1 623 normal children were included. Allele T compared with C,the differences between the study group and the control group were statistical-ly significant(P < 0. 05),the findings from the same TC + CC compared to TT and TC compared with TT + CC were similar. Japanese research findings were similar to those of China,but the differences between the study group and the control group had no statistical significance(P ﹥ 0. 05)in Hungary. The sensitivity analysis in each study was stable and the funnel graphics were basically symmetric. The results of sensitivity analysis and publication bias diagnostics demonstrated the reliability and stability of the Meta analysis. Conclusions TC + CC/ TT,TC/ TT + CC genotype and allele T/ C are related to the occurrence of childhood obesity in China,Japan,but there is no significant correlation with childhood obesity in Hungary. There are regional difference between β3 - AR gene polymorphism and genetic susceptibility to children obesity.

Objective To evaluate the relationship between vitamin D receptor(VDR) (rs731236)single nucleotide polymorphisms and genetic susceptibility to overweight/obesity in school-age children of Han and Kazakh in Xinjiang Uygur Autonomous Region.Methods The VDR gene rs731236 genotypes were detected by using polymerase chain reaction-restriction fragment length polymorphism method in 250 overweight/obesity school-age children(127Han,123 Kazakh) and 255 healthy controls(131 Han,124 Kazakh) as well.Results (1)There were statistically significant differences in the frequencies of rs731236 genotypes and alleles between the healthy controls of Han and Kazakh (x2 =9.904,P =0.005;x2 =9.312,P =0.002).(2)There were statistically significant differences in the frequencies of TT/Tt + tt genotype and the alleles between the overweight/obesity cases and healthy controls of Kazakh (x2 =3.891,P =0.049 ; x2 =5.871,P =0.015).But the difference in frequencies of rs731236 genotypes and alleles between the overweight/obesity cases and controls of Han were not statistically significant (x2 =0.064,P =0.800 ; x2 =0.190,P =0.663).(3)There were statistically significant differences in the frequencies of TT/Tt + tt genotype and alleles between the overweight/obesity cases and healthy controls of male school-age children of Kazakh (x2 =5.25,P =0.02;x2 =4.57,P =0.03),but the differences in frequencies of rs731236 genotypes and alleles between the overweight/obesity cases and controls were not statistically significant in female school-age children of Kazakh (x2 =0.06,P =0.80 ; x2 =1.40,P =0.24).There was no statistically significant difference in the frequencies of TT/Tt + tt genotype and alleles between the overweight/obesity cases and healthy controls of female school-age children of Han (x2 =0.04,P =0.84 ; x2 =0.04,P =0.84),and there was no statistically significant difference in male school-age children of Han(x2 =0.05,P=0.82;x2 =0.18,P=0.67).Conclusions VDR gene(rs731236)polymorphism bears ethnic diffe-rence.The polymorphisms of VDR gene polymorphism rs731236 are not associated with the susceptibility to overweight/obesity in school-age children of Han,while it is associated with the susceptibility to overweight/obesity school-age children in Kazakh,especially in male school-age children.

Recently, plasma sterilization has attracted increasing attention in dental community for the atmospheric pressure non-equilibrium plasma jet (APNPs), which is driven by a kilohertz pulsed DC power, may be applied to the dental and oral diseases. However, it is still in doubt whether APNPs can effectively kill pathogenic bacteria in the oral cavity and produce no harmful effects on normal oral tissues, especially on normal mucosa. The aim of this study was to evaluate the bacterial-killing effect of APNPs in the biofilms containing a single breed of bacteria (Porphyromonas gingivalis, P.g.), and the pathological changes of the oral mucosa after treatment by APNPs. P.g. was incubated to form the biofilms in vitro, and the samples were divided into three groups randomly: group A (blank control); group B in which the biofilms were treated by APNPs (the setting of the equipment: 10 kHz, 1600 ns and 8 kV); group C in which the biofilms were exposed only to a gas jet without ignition of the plasma. Each group had three samples and each sample was processed for up to 5 min. The biofilms were then fluorescently stained, observed and photographed under a laser scanning confocal microscope. In the animal experiment, six male Japanese white rabbits were divided into two groups randomly (n=3 in each group) in terms of the different post-treatment time (1-day group and 5-day group). The buccal mucosa of the left side and the mucosa of the ventral surface of the tongue were treated by APNPs for 10 min in the same way as the bacterial biofilm experiment in each rabbit, and the corresponding mucosa of the other sides served as normal control. The clinical manifestations of the oral mucosa were observed and recorded every day. The rabbits were sacrificed one or five day(s) after APNPs treatment. The oral mucosa were harvested and prepared to haematoxylin and eosin-stained sections. Clinical observation and histopathological scores were used to assess mucosal changes. The results showed the obvious P.g. biofilms were formed at 10 days, and most of the bacteria in groups A and C were alive under a laser scanning confocal microscope, but the bacteria in the group B were almost all dead. In animal experiment, no ulcers, anabrosis and oral mucositis were found in both the 1-day and 5-day groups. The average mucous membrane irritation index was -0.83 and -0.67 in the 1-day and 5-day groups, respectively, suggesting that no intense mucosal membrane irritation responses occurred. It was concluded that APNPs could effectively kill P.g. in the biofilms and did not cause any pathological changes in the normal mucosa, suggesting that the plasma jet (APNPs) may be applied to oral diseases as a novel sterilization device in the future.

Objective: To investigate the characteristics of traditional Chinese medicine (TCM) syndromes and their elements in patients with posthepatitic cirrhosis by analyzing the relationships between signs and symptoms and biochemical parameters. Methods: A total of 440 patients with hepatitis B cirrhosis treated in Shanghai Public Health Center and Shuguang Hospital, Longhua Hospital and Central Hospital of Putuo District Affiliated to Shanghai University of Traditional Chinese Medicine during January 2002 to January 2006 were enrolled in this study. Signs and symptoms and biochemical information of patients were collected by using a self-designed questionnaire regarding the four examinations of TCM. Signs and symptoms were firstly analyzed to find the frequency of occurrence. Then, the patients were divided into two groups according to non-existent or existent sign and symptom and the correlations between the signs and symptoms which occurred most frequently and their biochemical parameters were analyzed. Results: Sixteen symptoms which occurred most frequently were fatigue, colored urine, liver palms, opaque complexion, string-like pulse, weakness at waist and knees, dry month and bitter taste in the mouth, profuse dreaminess and poor sleepiness, heaviness of limbs, abdominal distention, yellow eyes, fine pulse, impetuosity and susceptibility to rage, splenomegaly, poor appetite, and distension and fullness in the chest and hypochondrium. A previous study on syndrome differentiation of 900 patients with posthepatitic cirrhosis showed 4 syndrome patterns: internal accumulation of dampness-heat, liver-kidney yin deficiency, internal accumulation of blood stasis-heat, and liver depression and spleen deficiency. Further analysis showed that internal accumulation of dampness-heat syndrome was characterized by obvious hepatic inflammation, poor synthesis function and more asctites. Liver-kidney yin deficiency syndrome was characterized by low-level hepatic inflammation, poor synthesis function and more ascites. Internal accumulation of blood stasis-heat syndrome was characterized by low-level hepatic inflammation, poorer synthesis function, ascites and splenomegalia, and liver depression and spleen deficiency syndrome was characterized by slight hepatic inflammation, synthesis function injury, decreased internal portal vein diameter and less ascites. Conclusion: Different syndrome patterns have different pathological features, showing the complexity and polymorphism of syndrome construction.

Objective To evaluate the sensitivity and specificity of different HbA1C cutoff points for diabetes diagnosis in high risk outpatients in Harbin.Methods A total of 2 122 high risk outpatients(male 1 032 and female 1 090)for diabetes screening in the Fourth affiliated Hospital of Harbin Medical University from April 2013 to February 2015 were included in this study, with the average age of(49.26±13.00)year. Oral glucose tolerance tests(OGTT)were conducted and HbA1C levels were examined in these patients. The sensitivity and specificity of different HbA1C cutoff points were calculated and a receiver operator characteristic(ROC)curve was then built.Results The average level of HbA1C in these subjects was(6.45±1.72)%. The prevalence of diabetes was 41.85%. The area under ROC curve(AUC)was 0.89 with the optimal cutoff point of HbA1C 6.0% and 0.68 for the highest Yonden index. The sensitivity and specificity of HbA1C 6.0% were 84.01% and 83.67% respectively. The sensitivity and specificity of HbA1C 6.5% were 62.84% and 95.92%, respectively. The AUC of HbA1C≥6.5% was 0.732. Conclusion HbA1C works well as the diagnostic standard for diabetes in high risk outpatients of Harbin city. The cutoff point of HbA1C 6.0% is suitable for screening diabetes in high risk population, and HbA1C 6.5% is appropriate for diabetes diagnosis, with high sensitivity and specificity.
