ObjectiveThe aim of this study is to analyze the etiology and status of bone age of children with short stat-ure.MethodsAnthropological and physical examination data were retrospectively collected and studied in 2132 children with short stature in the department of endocrinology between 2009 and 2014. Growth hormone (GH) levels were determined by ar-ginine-clonidine test. Bone age was determined by CHN scoring.ResultsAmong the 2132 patients, 1333 were males and 799 were females. Mean age is 9.03 ± 3.04 years old, mean bone age is 6.81 ± 3.05 years. Of them, 324 cases (15.2%) were diagnosed complete GH deifciency, 780 cases (36.59%) were partial GH deifciency, 27cases (1.27%) were multiple pituitary hormone de-ifciency, 13 cases (1.64%) were hypothyroidism, 893 cases (41.89%) were idiopathic short stature, 19 cases (0.89%) were small for gestational age (SGA), 40 cases (1.88%) were chromosomal disorders, etc. Signiifcant difference in age and bone age was found using t test (P<0.05). Signiifcant differences in Δage were found between etiological categories using ANOVA (P=0.000). Δage was signiifcantly and negatively associated with peak GH using Pearson's correlation.ConclusionsGH deifciency is the most common cause of short stature. Bone age of children with short stature is commonly delayed. Δage was signiifcantly and negatively associated with peak GH. Multiple pituitary hormone deifciency has a signiifcant effect on bone age. The etiology of patients with short stature cannot be determined just by bone age.

OBJECTIVE:
To explore the genetic basis for a sib pair featuring 17beta-hydroxysteroid dehydrogenase type 3 deficiency.
METHODS:
Genomic DNA was extracted from the proband, her sister, and their parents, and was subjected to sequencing analysis with a gene panel for sexual development. Suspected variant was verified by Sanger sequencing and bioinformatic analysis.
RESULTS:
Both the proband and her sister were found to harbor novel compound heterozygous missense variants of the HSD17B3 gene, namely c.839T>C (p.Leu280Pro) and c.239G>T (p.Arg80Leu), which were derived respectively from their mother and father. The variants were unreported previously and predicted to be deleterious by PolyPhen2, MutationTaster and other online software. Based on the American College of Medical Genetics and Genomics standards and guidelines, both c.839T>C(p.Leu280Pro) and c.239G>T (p.Arg80Leu) were predicted to be likely pathogenic (PM2+PP1+PP2+PP3+PP4, PM2+PM5+PP1+PP2+PP3+PP4).
CONCLUSION
The compound heterogeneous variants of the HSD17B3 gene probably underlay the disease in this sib pair. 17beta-hydroxysteroid dehydrogenase type 3 deficiency may lack specific clinical features and laboratory index, genetic testing can facilitate a definitive diagnosis.

Objective:To explore the effect of cognitive behavior orientation group psychotherapy on coping style, time management and family function of middle school students with internet addiction, and provide theoretical basis for the internet addiction psychotherapy system.Methods:Based on IAT, 70 internet addiction middle school students were screened and divided into control group and experimental group according to random number table method.The control group was only given conventionally psychological and drug treatments, the experimental group participated in cognitive behavioral orientation group psychotherapy on the basis of the treatment of the control group.Thirty-two people in the control group and thirty-three people in the experimental group completed the treatment.Before and after treatment, the two groups of middle school students were evaluated by the internet IAT, the SCSQ, the ATMD and the FAD.Results:There was no significant difference in the scales between the two groups of internet addiction middle school students before treatment (all P>0.05). After the intervention of the experimental group, the differences in the positive response (1.89±0.51), negative response (1.55±0.51), time monitoring (58.39±12.10), time value (26.64±4.48), time efficacy (30.42±5.18), and roles(18.85±2.40), communication(24.18±3.77), behavior control (18.82±2.57) and general functioning(24.79±3.90) of FAD were statistically significant compared with the control group (1.62±0.44), (1.84±0.55), (52.09±11.72), (19.34±3.96), (21.91±6.13), (21.16±2.63), (26.09±3.75), (20.59±2.54), (28.69±3.68) and the pre-intervention period (1.46±0.48), (1.97±0.56), (48.73±13.46), (18.27±4.84), (20.00±5.79), (21.76±2.72), (26.58±3.86), (19.76±2.96), (29.27±4.76) (all P<0.05). There were significant differences in problem-solving (12.67±2.50) and affective responsiveness (14.03±3.73) scores of the FAD between the experimental group and the pre-intervention group (14.15±2.83), (14.61±3.66) (all P<0.05). There were significant differences in SCSQ and ATMD before and after treatment in the control group (all P<0.05). Conclusion:Cognitive behavior orientation group psychotherapy can optimize the coping style, ameliorate their time management ability and significantly improve the role, communication, behavior control and overall function of family function of middle school students with internet addiction.

Due to the decline of motor ability and the impact of the diseases, abnormalities in gait is common in the elderly population, which will raise the risk of fall and cause serious injury. This study focuses on the analysis of the gait kinematics parameters of normal adults' gait, aiming to investigate the characteristics of gait parameters in different age groups and to explore the role of gait parameters in motor function assessment and clinical diagnosis. Based on the gait data gained by electronic walkway, the relationship among the toe out angles and their correlation with age and gender etc. were quantitatively analyzed. The results show that most normal subjects walk with positive toe out angles, and the angles increase with age. Such changes are slow in the young and middle age groups. However, the elevations of the left out toe angle and the angles between the feet are statistically significant after entering elder age ( >60 years). The results also suggest that the angle between the feet is a kind of practical gait parameter for varying applications. This study concludes that feet angle analysis is potential to provide a convenient and quantitative tool for the assessment of lower limb motor ability and the diagnosis of knee joint diseases.

HBeAg seroconversion refers to the disappearance of HBeAg and the appearance of anti-HBe in chronic hepatitis B (CHB) patients with positive HBeAg in the past. HBeAg seroconversion marks the reductions in viral replication, immune tolerance, and liver inflammation and is an important monitoring indicator for evaluating disease conditions and the effect of CHB antiviral therapy, and it also indicates the endpoint of satisfactory treatment. Exploring the influencing factors for HBeAg seroconversion is of great significance to the selection of treatment regimens and the prognostic evaluation of CHB patients. This article mainly elaborates on the association of HBV with HBeAg seroconversion in CHB patients from the aspects of virological factors, host genetic factors, drug factors, and immunological factors.
