Objective To investigate the correlation of anthropometric indicators and blood pressure in children. Methods A total of 6 790 children aged 6 to 13 years were inspected by random sampling. The body mass index (BMI), waist circumference (WC), hip circumference (HC), and blood pressure were measured. The waist/hip ratio (WHR) and waist/height ratio (WHtR) were calculated. The data wrer analyzed by SPSS16.0 statistical software. Results The detection rate of hypertension in children was 5.57%. After controlling for age, both in male and female children, the BMI, WC, HC, WHR, WHtR and systolic blood pressure showed a significant positive correlation by partial correlation analysis (all P<0.05). Both in male and female children, the BMI, WC, HC, WHR, and WHtR were significantly higher in children with hypertension than those in children with normal blood pressure (all P<0.05). Among all subjects, 280 children (4.12%) were obese, 622 children (9.16%) were overweight. The detection rates of hy-pertension were significantly different among obese, overweight and normal weight children (P<0.01). The detection rate of hypertension was significantly higher in obese children than that in overweight and normal weight children. The systolic and diastolic blood pressure were all significantly higher in obese and overweight children than that in normal weight children (P<0.05). Conclusion The hypertension prevalence of children aged 6 to 13 years in Zhengzhou is in the low to median level in the same age groups. The BMI, WC, HC, WHR, WHtR are signiifcantly correlated with blood pressure in both gender, and the correlation is the most obvious in HC.

Objective Boy sexual development is affected not only by age, but also by environment factors .The present study was to survey and evaluate the status of sexual development in boys from Zhengzhou area and to explore their influencing factors. Methods The height, weight, waist circumference, hip circumference, penis and testicles in 3779 boys aged from 6 to 13 years old in Zhengzhou were measured .The penis length and testicular volume of different ages and their influencing factors were compared, and the beginning age and sexual development characteristics were explored .The development of genitalia and pubes were evaluated by Tanner staging criteria and standards, which were divided into five stages. Results There were 3779 boys, including 395 overweight cases (10.45%) and 208 obesity cases (5.50%).The testicular volume and penis length increased by age, which increased slowly at the age of 6 to 11, followed by a rapid increase after the age of 11 year old.Testicular volume increased more rapidly than that of penis length. The medians quartile of testicular volume in overweight group ,obese group and normal group were 2.50 mL, 2.50 mL, 2.00 mL, 2.00 mL,2.00 mL,1.00 mL respectively .The testicular volume in overweight group and obese group were significantly greater than that in nor -mal group (P<0.01) and there were no difference between overweight group and obese group .The penis length in overweight group and obese group were significantly less than that in normal group (P<0.01), and there was no difference between overweight group and obese group.Testicular volume and penis length were positively correlated with age, height, weight, body mass index, waist circumference and hip circumference; the correlation between testicular volume and height, penis length and age were the strongest. The age of development of testicle (average 12.02 years) in urban area was later by 2.73 years than that in the rural area (average 9.9 years), the difference was statistically significant (P<0.001).The age of pubic development (P2) and maturity (P5) was (12.34 ±0.83) years and (12.39 ±1.24 ) years.The incidence of precocity in boys was 0.40%. Conclusion The sexual development of boys from Zheng-zhou area is similar to the results of large scale survey from China .Attention should be paid to the effect of obesity on sexual develop-ment, and early intervention should be given, the occurrence of adverse events of sexual development can be avoided .

BACKGROUND:Notch singling pathway is very important for cellproliferation and differentiation, but its role is stil unknown during chondrogenesis of human umbilical cord mesenchymal stem cells. OBJECTIVE:To investigate the effect of N-[N-(3,5-difluorophenacetyl-L-alanyl)]-(S)-phenylglycinet-butyl ester (DAPT) on inducing human umbilical cord mesenchymal stem celldifferentiation into chondrocytes. METHODS:Human umbilical cord mesenchymal stem cells were isolated from human umbilical cord, then were induced to differentiate into chondrocytes. There were four experimental groups:non-induced group, high-glucose Dulbecco’s modified Eagle’s medium containing 5%fetal bovine serum and 1%double antibody;induced group, induced medium containing 6.25 mg/L insulin, 6.25 mg/L transferrin, 10μg/L transforming growth factor beta 1, 0.1μmol/L dexamethasone, 50 mg/L vitamin C, 5%fetal bovine serum and 1%double antibody;dimethyl sulfoxide group, induced medium containing 0.1%dimethyl sulfoxide;DAPT group, induced medium containing 5μmol/L DAPT. RESULTS AND CONCLUSION:After chondrogenic induction, the morphology of human umbilical cord mesenchymal stem cells became polygon and positive for toluidine blue and immunofluorescence staining;the expression of Jag-1, PS-1, Notch-1 and Hes-1 decreased significantly (P<0.01). After the addition of DAPT, compared with the induced group, the relative gene expression of Jag-1, PS-1 and Hes-1 decreased markedly (P<0.01), the relative gene expression of Notch-1 decreased obviously as wel (P<0.05), and the contents of proteoglycan and col agen type II proteins decreased significantly (P<0.01). At the same time, the relative gene expression of proteoglycan decreased obviously (P<0.05), and the relative gene expression of col agen type II decreased in part. Notch signaling pathway exists in human umbilical cord mesenchymal stem cells, once chondrogenesis begins, the signaling strength wil decline rapidly. DAPT may prevent human umbilical cord mesenchymal stem cells from differentiating into chondrocytes by Jag-1-Notch-1-Hes-1 pathway.

Objective :
To investigate the epidemiological and clinical characteristics of cases with pertussis in Yiwu City, Zhejiang Province, so as to provide insights into pertussis diagnosis and control.
Methods:
A total of 186 patients with definitive diagnosis of pertussis in medical institutions in Yiwu City from November 1, 2020 to August 31, 2022 were recruited, and subjects' demographic, clinical symptoms and history of pertussis vaccination were collected using questionnaire surveys. The temporal, population, and spatial distribution and clinical symptoms of pertussis were analyzed using a descriptive epidemiological method, and the clinical characteristics of pertussis patients with different doses of pertussis vaccination were compared.
Results:
Pertussis was found to predominantly occur during the period between July and November (101 cases, 54.30%), and the three highest-incidence regions included Jiangdong Street, Beiyuan Street and Choujiang Street (87 cases, 46.77%). The 186 pertussis cases included 105 males (56.45%) and 81 females (43.55%), and included 144 cases with age of onset under 7 year (77.42%). Preschool and diaspora children were predominant among all pertussis cases, and the main clinical symptoms included spasmodic cough (97 cases, 52.15%), post-tussive vomiting (82 cases, 44.09%) and aggravated cough at night (77 cases, 41.40%). Routine blood tests measured 119 cases with abnormal white blood cell counts (63.98%), 137 cases with abnormal lymphocyte counts (73.66%), 39 cases with abnormal neutrophil counts (20.97%), 21 cases with abnormal platelet counts (11.29%) and 111 cases with abnormal hemoglobin concentrations (59.68%). There were 55 cases that were unvaccinated (29.57%), 23 cases that were not fully vaccinated (12.37%), and 108 cases that were fully vaccinated (58.06%). There were significant differences among pertussis cases with different doses of vaccination in terms of age, incidence of post-tussive vomiting, percentage of abnormal platelet counts and percentage of hemoglobin concentrations (all P<0.05).
Conclusions
The majority of pertussis cases are preschool and diaspora children in Yiwu City from November 1, 2020 to August 31, 2022, and the clinical symptoms mainly include spasmodic cough, post-tussive vomiting and aggravated cough at night, with atypical symptoms. The capability for differential diagnosis of pertussis is required to be improved in medical institutions.

Objective:To analyze the characteristics of clinical manifestation, auxiliary examination and gene mutation of 3-hydroxy-isobutyryl-coenzyme A hydrolase (HIBCH) deficiency to better understand this disease.Methods:The clinical manifestations and genetic results of a patient with HIBCH deficiency were analyzed. The clinical features and genetic characteristics of HIBCH deficiency were summarized based on the literature review.Results:The proband, female, one year and four months old, was admitted to Children′s Hospital Affiliated to Zhengzhou University for “vomiting and diarrhea for 15 days, dyspnea and intermittent convulsions for 13 days after digestive tract infection”. The intelligence was normal, however, the motor development was slightly delayed before onset. Physical examination showed light coma, poor response and insensitivity to light. She also had shortness of breath, weak positive three concave signs and coarse breath sound in both lungs with sputum purrs. In addition, the muscle tension of extremities was increased. Bilateral Brudzinski′s sign, Babinski′s sign and Kernig′s sign were negative. Serum hydroxybutyryl carnitine (C4OH) was increased. Cranial magnetic resonance imaging (MRI) showed atrophy in bilateral cerebral hemispheres and abnormal symmetry signals in bilateral globus pallidus and cerebral peduncle. Novel compound heterozygous variants of HIBCH, c.489T>A (p. C163*) and c.740A>G (p. Y247C), were found in the patient, which respectively inherited from her healthy parents. Her symptoms were relieved after“cocktail”therapy and symptomatic treatment. Literature related to HIBCH deficiency published all around the world was reviewed. As a result, 17 articles, including 24 cases, had been reported. The majority of patients presented with poor feeding, dystonia and progressive motor developmental delay in early infancy. Cranial MRI showed lesions in bilateral basal ganglia. Serum C4OH concentration was elevated. And compound heterozygous or homozygous variants of HIBCH gene were found in patients with HIBCH deficiency.Conclusions:The detection of serum amino acids and acylcarnitine profiles on HIBCH deficiency was relatively specific and it was helpful to make a clear diagnosis by combining with cranial MRI and genetic tests. In this study, a case of HIBCH deficiency was confirmed, which expanded the mutation spectrum of HIBCH gene. Meanwhile, summarizing the clinical and genetic characteristics of cases reported improved understanding of HIBCH deficiency.
