Objective To observe the prevalence of hyperuricemia(HUA)among obese children,and to ex-plore the association between uric acid(UA)levels and cardiometabolic risk factors,acanthosis nigricans and non - al-cohol fatty liver disease(NAFLD). Methods By using representative sampling method,1 753 obese children aged 6 -17 years old from 18 schools in 3 districts of Beijing(Xicheng,Haidian,Miyun)were selected to participate in the clini-cal examinations,including anthropometric measurements(height,weight)and blood pressure. Serum biochemical pa-rameters were assessed,including fasting plasma glucose(FPG),total cholesterol(TC),triglyceride(TG),high - densi-ty lipoprotein cholesterol(HDL - C),low - density lipoprotein cholesterol(LDL - C)and UA. Acanthosis nigricans and B - model ultrasonography of the liver were conducted. Results The prevalence of hypertension,impaired fasting glu-cose,dyslipidemia,acanthosis nigricans,and NAFLD among these 1 753 obese children was 33. 6%(589 cases), 66. 5%(1 156 cases),54. 3%(943 cases),23. 3%(408 cases),and 17. 0%(298 cases),respectively. The preva-lence of HUA was 40. 70%(714 / 1 753 cases),with 50. 17%(581 / 1 158 cases)in boys and 22. 34%(133 / 595 ca-ses)in girls. There was a significant increase in body mass index,systolic blood pressure,diastolic blood pressure, FPG,TG and LDL - C with the increase of UA,but there was a decrease in HLD - C with the increase of UA(all P ﹤0. 05). In boys,the adjusted odds ratios( OR)and 95% CI of the highest quartile of UA for hypertension,impaired fasting glucose,dyslipidemia,acanthosis nigricans,and NAFLD were 1. 16(0. 77 - 1. 74),1. 34(0. 90 - 1. 99),1. 29 (0. 89 - 1. 87),1. 89(1. 17 - 3. 04),and 1. 71(1. 03 - 2. 84),respectively;in girls,the adjusted OR and 95% CI of the highest quartile of UA for hypertension,impaired fas-ting glucose,dyslipidemia,acanthosis nigricans,and NAFLD was 0. 70(0. 40 - 1. 24),0. 60(0. 40 - 1. 00),1. 69(1. 04 - 2. 70),1. 67(0. 80 - 3. 49),and 1. 33(0. 48 - 3. 66),re-spectively. Conclusions The prevalence of HUA is relatively high in obese children and there is a strong association between UA and some car-diovascular metabolic disorders,acanthosis nigricans and NAFLD.

Objective:To explore the effect of the teaching reform of "Community Nursing" in our school in different grades of nursing undergraduates.Methods:A total 174 nursing students in Grade 2009, 2010 and 2013, from School of Nursing at Shanghai Jiao Tong University were selected. Various teaching methods were carried out, including continuously carding teaching content, gradually adopting a community assessment approach, participating in community health education, and developing family health education plans and student-centered teaching methods. At the end of the course, all students completed the self-design curriculum evaluation questionnaires. By comparing the evaluation of teaching reform in different grades, the effect of the teaching reform scheme was analyzed. One-way analysis of variance and student Newman Keuls method were performed to compare the differences among different grades with SPSS 19.0 software.Results:The scores of the five dimensions of "curriculum organization", "teaching content", "teaching form", "teaching evaluation" and "teaching arrangement" were much higher in Grade 2013 and 2010 than in Grade 2009 ( P<0.05). After the teaching reform, students' satisfaction with the curriculum organization was improved; simplifying the teaching content reduced the repetition between courses; implementing the diversified teaching form enhanced students' participation; adopting a diversified teaching evaluation system expanded students' understanding of learning content; integrating different teaching locations and equipment brought real service experience to students. Conclusion:The series of teaching reforms of "Community Nursing" have achieved positive results in adjusting the curriculum framework, focusing on community nursing, improving students' participation, combining varied assessment methods and developing multiple teaching points and have been recognized by the students, so that the results may provide a reference for the next teaching rounds of "Community Nursing" with the fourth edition.

Objective:To observe the effect of Ba Duan Jin(Eight-brocade Exercise)plus Tuina(Chinese therapeutic massage)in treating primary dysmenorrhea due to cold-induced blood stasis in female college students and on the score of fatigue scale-14(FS-14). Methods:Seventy-two female college students with primary dysmenorrhea due to cold-induced blood stasis were randomized into a Tuina group and a joint group,with 36 cases in each group.The Tuina group only received Tuina manipulations.In the joint group,besides the same Tuina manipulations,patients practiced Ba Duan Jin.For both groups,the once-daily intervention was conducted from 6 d before the menstrual period until menstrual day 1 for 3 menstrual cycles.Changes in the scores of COX menstrual symptom scale(CMSS),visual analog scale(VAS),and FS-14 after the intervention were observed.Clinical efficacy was also estimated. Results:During the process,1 case dropped out in the Tuina group,and 35 cases completed the intervention;2 cases dropped out in the joint group,and 34 cases completed the intervention.The total effective rate was 94.1%in the joint group,higher than 88.6%in the Tuina group(P<0.05).After treatment,the symptom duration and intensity scores in the scores of CMSS,VAS,and FS-14 declined in both groups(P<0.05 or P<0.01);the CMSS symptom duration score and FS-14 score were lower in the joint group than in the Tuina group(P<0.05). Conclusion:Tuina manipulations alone or combined with Ba Duan Jin practice can effectively treat primary dysmenorrhea due to cold-induced blood stasis in female college students;when combined with Ba Duan Jin practice,Tuina manipulations can more significantly improve pain duration and fatigue,suggesting the advantages of combining Tuina Gongfa and manipulations.

Objective To establish a cell line stably expressing the human CD36 by using TA clo-ning and cell transfection technology and to analyze its application to the detection of anti-CD36 antibodies. Methods Total RNA was isolated from human platelets and then used to synthesize complementary DNA ( cDNA) . Sequence of the gene encoding CD36 on human platelets was obtained by PCR amplification. The recombinant vector was transformed into TOP10 E. coli after TA cloning. The positive recombinant pcDNA3. 1/V5-CD36 plasmid was screened out by blue-white selection and then sequenced. The correctly constructed plasmid coated with Effectene? Transfection Reagent was transferred into HEK293T cells. Fluo-rescence-activated cell sorting was performed to screen out the cell line that could stably express the CD36 on human platelets. The transfected cell line-based flow cytometry analysis and antibody capture assay ( ACA) were established and used for antibody detection in nine serum samples positive for anti-CD36 antibodies. Results The HEK293T cell line stably expressing the recombinant CD36 was successfully established. Compare with the monoclonal antibody immobilization of platelet antigens assay ( MAIPA) , anti-CD36 anti-bodies could be easily identified in nine serum samples by using the transfected cell line-based flow cytome-try analysis and ACA. Conclusion This study suggests that the HEK293T cells stably expressing the re-combinant CD36 could be used in flow cytometry analysis and ACA for the detection of anti-CD36 antibod-ies. It also paves the way for further researches on the mechanism of CD36 in other diseases.

Objective:To investigate the clinical efficacy of Omalizumab in the treatment of moderate-to-severe allergic asthma with allergic comorbidities in children.Methods:The clinical data of 50 children with moderate-to-severe allergic asthma and allergic comorbidities, who were treated with Omalizumab and completed 12-month follow-up in the Department of Pediatrics of Peking University First Hospital from July 2018 to March 2022, were retrospectively analyzed.A comparison was performed on the scale scores of childhood allergic asthma and allergic comorbidities including allergic rhinitis (AR) and chronic spontaneous urticaria (CSU), pulmonary function test indices and fractional exhaled nitric oxide (FeNO) concentration before and after treating with Omalizumab.The data were compared by ANOVA, paired t-test, chi- square test and rank sum test. Results:(1)Improvement of clinical symptoms: after 12 months of Omalizumab treatment, the childhood asthma control test score of 42 children aged ≤11 years increased from (20.98±5.03) points to (26.95±0.22) points ( F=18.189, P<0.001). The asthma control questionnaire 7 score of 50 children decreased from (0.89±0.11) points to (0.10±0.02) points ( F=5.662, P=0.006). The score of visual analogue scale of 47 children with AR decreased from (11.00±1.65) points to (0.2±0.14) points ( F=14.901, P<0.001), and the urticaria control test score of 13 children with CSU decreased from (4.82±0.88) points to (1.87±0.61) points ( F=4.329, P=0.018). (2)Improvement of quality of life: compared with those before treatment, the pediatric asthma quality of life questionnaire score in 50 children increased from (124.50±32.13) points to (159.40±6.21) points ( F=12.052, P<0.001), and global evaluation of asthma treatment effectiveness decreased from (2.23±0.70) points to (1.07±0.26) points ( F=68.865, P<0.001) after Omalizumab treatment for 12 months.(3)Improvement of pulmonary function results: after 12 months of Omalizumab treatment, the number of children with forced expiratory volume in one second/forced vital capacity< 80% decreased from 13 cases (26%) to 1 case (2%), and the values increased from (91.39±12.88)% to (96.96±8.54)%( χ2=11.960; t=2.486, all P<0.05). The peak expiratory flow of predicted value increased from (86.73±16.05)% to (94.01±13.11)% ( t=2.445, P<0.05). The number of children with two indicators among the forced expiratory flow at 50% of forced vital capacity exhaled, forced expiratory flow at 75% of forced vital capacity exhaled and maximal mid-expiratory flow lower than 65% decreased from 31 cases (62%) to 7 cases (14%) ( χ2=24.450, P<0.001). There was no significant difference in FeNO concentration before and after treatment ( P>0.05). Safety of Omalizumab: no obvious adverse reactions were found during treatment and follow-up. Conclusions:Omalizumab can significantly improve the clinical symptoms, small airway function and quality of life of children with allergic asthma and concomitant AR or CSU.It is a potential targeted drug for treating a variety of allergic diseases in children.

OBJECTIVE: To construct eukaryotic expression vectors for human platelet CD36 gene 220 C>T and 429+4insg variants and analyze their expressions in HEK293T cells. METHODS: RNA was isolated from human platelets and reversely transcribed into cDNA. Sequences of 220C>T and 429+4insg variants were derived by PCR amplification. The target sequence was ligated into a pcDNA3.1/V5-His-TOPO vector by TA cloning, which was transformed into TOP10 E. coli. Positive plasmids were screened by blue-white selection. After sequencing, plasmid DNA carrying 220C>T or 429+4insg variant was used to transfect HEK293T cells with the help of effectene. Expression of CD36 protein was then analyzed by flow cytometry and Western blotting. RESULTS: An eukaryotic expression vector pcDNA3.1/V5-His-CD36 (220C>T/429+4insg) was constructed by TA cloning. After transfected into HEK293T cells, the 220C>T and 429+4insg variants resulted in CD36 deficiency in HEK cells, which was confirmed by flow cytometry and Western blotting. CONCLUSION The 220C>T and 429+4insg variants can cause CD36 deficiency in human platelets. This system may be used for assessing the effect of 220C>T, 429+4insg, and other variants on the expression of CD36.
