Objective By observing the clinical efficacy of acupuncture plusBu Shen Jie Yu Qing Xin decoction (herbal decoction for tonifying kidney, anti-depression and clearing heart fire) in treating perimenopausal depression, to discuss about the effect of acupuncture plus medication on Hamilton Depression Scale (HAMD), Self-rating Depression Scale (SDS) and hypothalamic-pituitary-ovarian (H-P-O) axis in perimenopausal depression patients.Method By following a completely randomized design, sixty perimenopausal depression patients were divided into a Chinese medication group (Bu Shen Jie Yu Qing Xin decoction) with 30 cases, and an acupuncture-medication group (acupuncture plusBu Shen Jie Yu Qing Xin decoction) with 30 cases, to receive 12-week treatment in total. The HAMD and SDS were estimated prior to the treatment and in the 4th, 8th and 12th weeks; the serum follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), testosterone (T), prolactin (PRL), and progesterone (P) contents were detected before and after the treatment.Result Acupuncture plus medication and Chinese medication alone were both effective in treating perimenopausal depression, and the therapeutic efficacy of acupuncture plus medication was superior to that of Chinese medication alone (P<0.05). In the acupuncture-medication group, the HAMD score dropped significantly in the 4th, 8th and 12th weeks compared to that before the treatment, and the score dropped significantly in the 8th and 12th weeks compared to that before the treatment in the Chinese medication group (P<0.01). The HAMD score in the acupuncture-medication group was significantly lower than that in the Chinese medication group in the 4th, 8th and 12th weeks (P<0.01). After the treatment, the items including anxiety, insight, sleep, and despair were significantly changed in the Chinese medication group (P<0.05); 7 items were significantly changed in the acupuncture-medication group (P<0.05). The scores of anxiety, insight, sleep, diurnal-nocturnal, obstruction, and body weight in the acupuncture-medication group were significantly superior to those in the Chinese medication group (P<0.05). The SDS score dropped significantly in the 4th, 8th and 12th weeks in the acupuncture-medication group, and in the 8th and 12th weeks in the Chinese medication group (P<0.01,P<0.05); in the 4th and 8th weeks, the SDS score in the acupuncture-medication group was significantly lower than that in the Chinese medication group (P<0.05), while the between-group difference was statistically insignificant in the 12th week (P>0.05). After 12-week treatment, the contents of FSH and LH declined significantly in both groups (P<0.01, P<0.05), and the contents of E2 and T increased significantly in the acupuncture-medication group (P<0.01,P<0.05). The decrease of FSH and LH, and the increase of E2 were more significant in the acupuncture-medication group (P<0.05,P<0.01).Conclusion Acupuncture plus medication can improve the symptoms of perimenopausal depression, and it takes a faster action than Chinese medication alone. Acupuncture plus medication can mitigate 7 items in HAMD, while Chinese medication can improve anxiety, insight, sleep and despair. Acupuncture plus medication can produce a more significant efficacy in improving anxiety, insight, sleep, diurnal-nocturnal, obstruction, and body weight compared to Chinese medication. For perimenopausal depression, acupuncture plus medication can correct the endocrine disorder and improve depression state by down-regulating the levels of FSH and LH, and up-regulating the contents of E2 and T to improve the function of H-P-O axis.

Objective: To investigate the association between cysteine level and lumbar spine (LS) bone mineral density (BMD) among children with cerebral palsy, so as to provide a basis for bone health enhancement among children with cerebral palsy. Methods: A total of 149 children aged 10-18 with cerebral palsy who were admitted to the G city Social Welfare Institute (Luogang District) from January 2023 to January 2024. Basic demographic characteristics of children with cerebral palsy were extracted from medical records system. Cysteine levels were measured using the enzyme cycling method. LS BMD of the children was determined by specialized rehabilitation physicians using dual energy X ray absorptiometry, and the corrected BMD Z -scores for LS were calculated. Non restrictive cubic splines and segmented multiple linear regression were employed to analyze the correlation between cysteine levels and age specific height Z -scores (HAZ scores) for LS BMD in children with cerebral palsy. Results: The median cysteine concentration in children with cerebral palsy was 9.13(8.42, 10.30)μmol/L, with significantly higher levels in spastic type children [9.28(8.53，10.49)μmol/L] compared to non spastic types [8.64(7.89，9.66)μmol/L]( Z=-2.46，P <0.05). The median LS BMD HAZ score was -1.07( -2.10 , -0.16), and the detection rate of decreased bone mass was 29.5%. There was an "L" shaped association between serum homocysteine concentration and LS BMD HAZ score in children with cerebral palsy. When serum homocysteine concentration was below 8.7 μmol/L, a significant negative correlation was observed between LS BMD HAZ score and serum homocysteine concentration ( B=-0.32, 95%CI =-1.06 to -0.15, P <0.05). Conclusions The significant negative correlation between cysteine levels and LS BMD in children with cerebral palsy at lower cysteine concentrations, which suggests a potentially higher sensitivity to the influence of homocysteine than healthy children and adolescents, warranting attention even if not reaching the standard of hyperhomocysteinemia.

Objective: To investigate the correlation of emotional and behavioral problems with sleep problems in children with cerebral palsy, so as to provide reference for intervention of emotional and behavioral problems in children. Methods: A cross sectional survey was conducted, and 402 children aged 6-18 with cerebral palsy who were adopted by social welfare institutions in Guangzhou City from January 2023 to January 2024 were selected to investigate their full time nurses. The Parents Strengths and Difficulties Questionnaire (SDQ) was used to assess the emotional and behavioral problems of children with cerebral palsy, and the Children s Sleep Habits Questionnaire (CSHQ) was used to assess sleep problems. Multiple linear regression analysis was used to analyze the correlation between the sleep problem of children with cerebral palsy and the emotional and behavioral problems. Results: The prevalence of emotional and behavioral difficulties among children with cerebral palsy was 15.7%. The median sleep problem score of children with emotional and behavioral problems [37.0(36.0, 41.0)] was significantly higher than that of children without emotional and behavioral [35.0(34.0, 36.0)] ( Z =-5.74, P <0.01). The results of multiple linear regression analysis showed that after adjusting covariables such as age, gender, cerebral palsy classification, language retardation, visual impairment and epilepsy, the total sleep problem score of children with cerebral palsy was positively correlated with the total difficulty score ( β= 0.28, 95%CI =0.17-0.34, P <0.05). Conclusions Sleep problems in children with cerebral palsy are associated with emotional and behavioral difficulties. Understanding of the management of sleep problems in children with cerebral palsy should be enhanced to reduce the incidence of emotional and behavioral problems in children with cerebral palsy.
