To treat large facial defect (more than 6 cm x 4 cm in diameter) or a wound with bone exposure to atmosphere by less-traumatic, easier-healing reconstruction method, a pedicle flap including facial, neck, posterior auricle and occipital skin flap was designed and transferred, one by one, to repair facial defect as well as other flap donor sites, but occipital skin flap was only used to cover posterior auricle area. After 2-3 years follow-up, well-healed skin flaps with good color, elasticity and sensation were observed in all 16 patients. It is concluded that this method is effective and practical.

Objective: This study aims to explore the influence of birth order and age difference on the emotional and behavioral problems among children from two-child family, so as to provide advice on parenting. Methods: A total of 482 students in grades 2 to 5 from the 5 primary schools in Guangzhou were selected, all of whom came from two-child families (excluding twin children). Emotional and behavioral problems were investigated by using the Conner’s Parental Symptom Questionnaire (PSQ). Results: Among children from two-child families, higher prevalence of behavioral problems, learning problems, impulsive hyperactivity and hyperactivity index in older compared with younger children (β=-0.09，-0.16，-0.09，-0.10,P<0.05). The scores of behavioral problems and hyperactivity index were significantly higher among those of children who were 6-9 years older than young siblings, compared to those who were 0-3 years older than younger siblings(β=0.20,0.21,P<0.05). No similar pattern was found among the younger siblings(P>0.05). Conclusion Among school-age children from two-child families, emotional and behavioral problems of the elder ones were more serious than the younger ones’. Age difference between siblings shows impact on the emotional and behavioral development among elder children, however no significant impact is noticed among the younger ones.

ObjectiveTo systematically review the effect of rhythmic auditory stimulation on gait of patients with cerebral palsy. MethodsRelevant literature on gait improvement of patient with cerebral palsy by rhythmic auditory stimulation were retrieved from Web of Science, PubMed, EBSCO, CNKI and Wanfang database from establishment to December, 2022. Physiotherapy Evidence Database (PEDro) scale was used to evaluate the methodological quality of the articles, and the relevant data was extracted. A systematic review was conducted. ResultsA total of 1 339 literatures were retrieved, and ten were finally included. The patients mainly came from America, Egypt, Israel, South Korea and Greece. The intervention sites were mainly in hospitals and communities, and some patients received home-based intervention. The publication date was mainly after 2010. Adding rhythmic auditory stimulation on the basis of conventional rehabilitation training increased the range of motion of the joints of patients with cerebral palsy; improved the walking speed, step length and stride length; improved the movement mode, and enhanced the intervention effect of gait training. ConclusionRhythmic auditory stimulation is effective on the range of motion, walking speed, step length and stride length of patient with spastic cerebral palsy, which can improve gait.

To improve the cavitation-to-tissue ratio (CTR) of cavitation imaging during the treatment with high-intensity focused ultrasound (HIFU), we proposed a pulse inversion based broadband subharmonic cavitation imaging method (PIBSHI). Due to the fact that the subharmonic signal is a unique nonlinear vibration characteristic of cavitation bubbles, we extracted the broadband subharmonic signal to get a high-CTR cavitation imaging. The simulation showed that the subharmonic signal produced by cavitating bubbles with different sizes varied, and the signal was stronger than other subharmonics when the bubbles' resonant frequency was close to 1/2 subharmonic frequency. Further experiment results demonstrated that compared with the conventional B-mode images, broadband subharmonic cavitation imaging (BSHI) has improved the CTR by 5.7 dB, and the CTR was further improved by 3.4 dB when combined with pulse inversion (PI) technology. Moreover, when the bandwidth was set to 100%~140% of the 1/2 subharmonic frequency in PIBSHI, the CTR was the highest and the imaging showed the optimal quality. The study may have reference value for the development of precise cavitation imaging during HIFU treatment, and contribute to improve the safety of HIFU treatment.
