Aim To study the distribution of CYP2C19,ABCB1,and PON1 genotypes and their correlation with clopidogrel resistance in patients with coronary heart disease in Tai'an.Methods A total of 594 patients with coronary heart disease who were treated with clopidogrel during hospitalization in Tai'an Central Hospital from January 2019 to March 2020 were selected.Fluorescence in situ hybridization was used to detect CYP2C19*2(rs4244285),CYP2C19*3(rs4986893),CYP2C19*17(rs12248560),ABCB1(rs1045642)and PON1(rs662)gene types.Results CYP2C19*2,CYP2C19*3,CYP2C19*17 genotypes in patients with coronary heart disease in Tai'an were mainly with homozygous(GG).The frequencies of CYP2C19*2 GG,CYP2C19*3 GG,CYP2C19*17 CC,ABCB1 CT and PON1 AG were 48.0％,89.6％,97.0％,46.8％and 47.1％respectively.There was no significant difference in CYP2C19*2,CYP2C19*3,CYP2C19*17,ABCB1,PON1 genotype distribution and allele distribution between male and female patients(P＞0.05).Significant regional differences in the frequency of CYP2C19 alleles and the distribution of metabolic types were found in patients with coronary heart disease in Tai'an.Among 594 patients included in the study,there were 287 patients with a risk level of clopidogrel resistance ≥ 2 in the composite evaluation of patients,approximately 48.3％of the total number of patients.This indicated that clopidogrel resistance was present in 48.3％of patients on the regular dose of clopidogrel.Of the 287 people with a risk level ≥2,46 had a normal CYP2C19 metabolic type,representing approxi-mately 7.7％of the total number of patients.Conclusion There were gene polymorphisms observed in CYP2C19*2,CYP2C19*3,CYP2C19*17,ABCB1 and PON1 distribution in patients with coronary heart disease in Tai'an,and ABCB1 and PON1 gene polymorphisms would had an impact on the outcome of medication guidance in approximately 7.7％.

It is difficult to treat severe burn combined injury caused by high voltage. This paper reports the successful treatment of a patient with large cranial area third degree burn, skull exposure, local skull carbonization combined with cerebrospinal fluid leakage caused by ten thousand volts high voltage current. Vacuum sealing drainage was given to protect the wounds from infection after multiple limited debridement in the early stage. The external of the inactivated skull was cleaned in the later stage. Finally, the bilateral anterolateral thigh flap combined with multiple burr holes was used to repair the wound. There were no severe postoperative complications, and the therapeutic effect was satisfactory.

Objective: To identify the lifestyle pattern of adolescents in Guangzhou and to provide a scientific basis for targeted and individualized interventions for adolescents with different lifestyle pattern. Methods: A survey was conducted by questionnaire among 12 540 students from 27 middle schools in the urban area of Guangzhou using a convenient sampling method. The latent class model (LCM) was used to identify lifestyle patterns of adolescents, and further analyses were conducted to compare differences in dietary habits and willingness to exercise among the different classes. Results: Three lifestyle patterns were identified based on the latent class model: "high sweet snacks/excessive screen time, sleep and exercise deficiency group", 3 797 people, accounting for 30.3%; "low nutrition diet/severe sleep and exercise deficiency group", 2 745 people, accounting for 21.9%; "general diet/sleep and exercise deficiency group", 5 998 people, accounting for 47.8%. Adolescents of different classes had different perceptions of their eating habits and different degrees of willingness to participate in physical exercise, these differences were statistically significant(χ 2=671.54, Z=153.16, P<0.05). Conclusion The results of the latent class model showed that the three classes of adolescents had their own unique characteristics. It is necessary to inform them of their needs, provide guidance and implement targeted interventions according to the unique characteristics of the different lifestyle patterns in empirical work.

Objective: To investigate the prospective effects of the consumption of protein and animal foods before menarche on the age at menarche among Chinese girls. Methods: This paper was based on the data collected in the China Health and Nutrition Survey(CHNS) from 1997 to 2015. A total of 683 girls aged 6 and over who had completed information on age at menarche, height, weight, per capita annual household income, maternal education level and participated in at least one complete dietary survey within 1 to 4 years before menarche were included. Urban-rural stratified multivariable linear regression model was used to examine the effects of protein and animal foods intake before menarche on Chinese girls age at menarche in urban and rural areas. Results: After adjusted for total energy intake, body mass index standard deviation score and per capita annual household income, the consumption of meat before menarche was negatively associated with the age at menarche among rural Chinese girls(B=-0.003, P=0.00), but not among urban Chinese girls(B=0.002, P>0.05). Total protein, dairy, eggs and aquatic products intake before menarche were not associated with Chinese girls age at menarche in urban and rural areas(B=0.002, -0.001, 0.003, 0.000; 0.001, 0.001, -0.001, -0.003, P>0.05). Conclusion Higher intake of meat before menarche might lead to earlier menarche onset in rural Chinese girls. The consumption of total protein, dairy, eggs, and aquatic products before menarche did not affect the age at menarche in Chinese girls.

Objective: To evaluate effects of mobile health intervention on vegetables and fruits intakes, screen time, body mass index, BMI Z score and waist circumference in children and adolescents. Methods: The literature search was performed to find articles published up to December 2018 in the databases: PubMed, Embase, Cochrane Library, CNKI, Wanfang. The articles focusing on the keywords of "prevention" "children" "adolescents" "obesity" "weight loss" "m-Health" "mobile phone" "mobile application" "mobile techonology" "cell phone" "smartphone" "mobile apps" for the delivery of children and adolescents obesity interventions were included. Stata 13.0 software was used for Meta-analysis. Results: A total of 15 studies were included, and mobile health had an effect on the vegetables and fruits intakes and screen time for children and adolescents. Mobile health was more effective in the intervention participants compared to controls, the standardized mean difference (SMD) and 95%CI were 0.54 (95%CI=0.27-0.81) and -0.32(95%CI=-0.47--0.18),respectively. However, no statistical differences in the BMI, BMI Z score and waist circumference were found between intervention and control groups. Conclusion The effect of mobile health intervention on obesity in children and adolescents needs more long-term follow-up and larger sample size studies to clarify.

Bladder cancer is a common malignant tumor in the urinary system, and its drug-resistant recurrence has become a major problem in clinical treatment. At present, there is still a lack of molecular markers for effectively predicting bladder cancer resistance. The mechanisms for drug resistance in bladder cancer is very complicated. The common mechanisms of drug resistance include epigenetic modification, abnormal expression level, abnormal regulation of non-coding RNA, production of bladder cancer stem cells, increase of drug efflux and autophagy. The various drug resistance mechanisms of bladder cancer are not independent, but there is a certain relationship between them, which leads to the occurrence of drug resistance. Further study on the mechanisms for bladder cancer resistance is of great importance to overcome these problems.
