Effects of umbilical cord mesenchymal stem cells on expression of CYR61, FSH, and AMH in mice with premature ovarian failure.

This study aimed to investigate the effects of umbilical cord mesenchymal stem cells on the expression of CYR61, FSH and AMH in mice with premature ovarian failure. For this purpose, thirty SPF female SD mice were selected as the research object, 10 of which were control group, namely group α, and 20 mice with premature ovarian failure model were established by cyclophosphamide. The mice were divided into the model group, namely the ß group and the umbilical cord mesenchymal stem cell transplantation group (γ group), with 10 mice in each group. ELSA method was used to determine the levels of follicle-stimulating hormone (FSH), Luteinizing hormone (LH), estradiol (Estradiol) in serum. The changes of E2, Antimullerian hormone (AMH) and cysteine-rich protein 61 in ovarian tissues were determined by the protein imprinting method. Connective tissue growth factor (CTGF) and caspase-3 protein expression. Results showed that in fertility rate, γ group > α group > ß group, the difference was statistically significant (P<0.05), in litter size, α group > γ group > ß group, the difference was statistically significant (P<0.05). The levels of serum E2 and AMH in α group > γ group > ß group, and the levels of serum FSH and LH in ß group > γ group > α group were statistically significant (P<0.05). The growth follicles were α group > γ group > ß group, and the atresia follicles were ß group > γ group > α group, and there was a statistical difference among all groups (P<0.05). There was no difference in luteal number among the three groups (P>0.05). In terms of CYR61 and CTGF protein expression, α group > γ group > ß group, and in terms of caspase-3, ß group > γ group > α group had statistical significance (P<0.05). It is concluded that intervention with umbilical cord mesenchymal stem cells can significantly improve the expression levels of CYR61 and AMH, reduce the level of FSH, promote cell survival, improve the reproductive quality of mice, and restore the physiological function of the ovary. It is feasible to treat premature ovarian failure with umbilical cord mesenchymal stem cells.

Characteristics of Voice of 3~6 Years Old Hearing-impaired Children / 中国康复理论与实践

Objective To investigate the acoustic characteristics of the voice of 3~6 years old children with hearing-impairment. Meth-ods The voice samples were collected from 148 hearing-impaired children and 122 normal children, all aged 3~6 years. The acoustic param-eters including F0, F0SD, jitter, shimmer, NNE, OQ, SQ, AQ, STF were compared. Results The F0, SQ, STF, F0SD, jitter were more in the children with hearing-impairment than in the normal children (P0.05). There was no significant difference of all the acoustic parameters among chil-dren with different ages (P>0.05), except the NNE was less in 3~4 years old children than 5~6 years old children (P0.05). Conclusion The vibration of vocal cords is instable and ir-regular, saying overquick and close intensely in hearing-impaired children. The age and sex do not influence the acoustic parameters, except NNE is less in younger children.

A comparative study of the speech respiratory characteristics of 7-15 years old ordinary children and children with spastic cerebral palsy / 中华物理医学与康复杂志

Objective To explore the speech respiratory characteristics of 7-15 years old children with spastic cerebral palsy and the differences between ordinary children and children with cerebral palsy.Methods The maximum phonation time (MPT) and maximum counting ability (MCA) of 90 ordinary children and 58 children with cerebral palsy aged 7-15 years were measured and a comparison between the 2 groups were conducted.Results (1) Age has significant effects on MPT and MCA of the ordinary children (P ＜0.05).The MPT and MCA of the ordinary children at the age of 7 ～9 years and 10 ～ 12 years are lower than the ones at the age of 13 ～ 15 years.Age has almost no effects on MPT and MCA of children with cerebral palsy(P ＞0.05) ; (2)Sex has no significant effects on MPT and MCA of ordinary children and children with cerebral palsy (P ＞0.05) ; (3) The MPT and MCA of children with cerebral palsy are significantly lower than those of ordinary children (P ＜0.05).Conclusions The MPT and MCA of ordinary children are increased with the growth of age,especially after the age of 13 years,but the children with spastic cerebral palsy do not show that kind of trend and demonstrate a state of retardation of speech respiratory function.Compared with ordinary children,the children with spastic cerebral palsy are easier to suffer from insufficient respiratory support and poor respiratory-phonatory coordination.

Objective To investigate the cause and nursing of the abdominal incision dehiscence.Methods The clinical data of 18 cases of abdominal incision dehiscence after surgery were analyzed retro-spectively from January 1998 to June 2008 in our hospital.Results Abdominal wound dehiscence was caused by various factors,such as basic disease,anesthesia during operation,suture techniques and postop-erative care.Conclusions We should pay attention to the relevant factors of incision dehiscence and make the appropriate care and treatment when patients are admitted to hospital.Correction of malnutrition,strengthening the treatment of basic disease,attention to suture technique ale helpful for reducing the inci-dence of abdominal incision dehiscence.
