Objective:To investigate the effect of horticultural therapy on postpartum posttraumatic stress disorder and medical coping method of perinatal depression patients and to provide reference for perinatal depression patients.Methods:A total of 124 perinatal depression patients in Xuchang Maternity and Child Health Hospital from January 2018 to December 2019 were divided into experimental group (62 cases) and control group (62 cases) by random digits table method. The control group received routine nursing, while patients in the experimental group carried out horticultural therapy based on the outine nursing. Before and after intervention, the depression levels were assessed by Postpartum Depression Screening Scale (PDSS), posttraumatic stress was evaluated by Posttraumatic stress CheckList-Civilian version (PCL-C), medical coping method was assessed by Medical Coping Method Questionnaire (MCMQ), respectively.Results:There was no significant difference in the score of PDSS, PCL-C, MCMQ before intervention between the two groups( P>0.05). After intervention, the scores of sleeping/eating disturbance, anxiety/insecurity, emotional lability, cognitive impairment, guilt/shame, contemplating harming oneself, and total PDSS were (8.95 ± 1.37), (9.53 ± 1.57), (10.02 ± 0.79), (7.78 ± 1.43), (9.36 ± 1.81), (7.14 ± 1.56), (61.86 ± 3.78) points in the experimental group, significantly lower than those in the control group (10.11 ± 1.45), (10.96 ± 2.41), (10.81 ± 1.43), (8.61 ± 1.67), (10.35 ± 1.64), (7.84 ± 1.72), (67.93 ± 5.12) points, the differences were statistically significant ( t values were 2.320-7.239, P<0.05). The scores of arousal symptoms, avoidance/numbing, re-experiencing symptoms and total PCL-C were (7.12 ± 0.81), (9.12 ± 1.61), (5.42 ± 1.09), (21.66 ± 2.03) points in the experimental group, significantly lower than in the control group (7.93 ± 1.32), (9.81 ± 2.07), (6.16 ± 1.35), (23.89 ± 2.37) pionts, the differences were statistically significant ( t values were 2.001-5.463, P<0.05). The MCMQ scores in avoidance and yielding were (10.78 ± 2.14), (9.81 ± 2.74) points in the experimental group, significantly lower than in the control group (11.89 ± 2.78), (10.86 ± 2.66) points; their score of facing were (17.39 ± 2.59) points in the experimental group, significantly higher than in the control group (15.95 ± 2.63) points, the difference was statistically significant ( t values were 2.413, 2.971, 2.085, P<0.05). Conclusions:Horticultural therapy can alliviate depression, decrease postpartum posttraumatic stress disorder and promote medical coping method of perinatal depression patients.

Objective:To investigate the effect of Pilates exercise therapy therapy on the bladder function and quality of life of postoperative patients with cervical cancer in young and middle-aged patients.Methods:A total of 124 cases of postoperative patients with cervical cancer in young and middle-aged patients treated in Xuchang Maternity and Child Health Hospital, Henan Province, from January 2018 to December 2019 were divided into experiment group and control group according to the admission time, each group were 62 patients. Participants in the control group received pelvic floor training, while the experiment group carried out Pilates exercise program for three months. The duration of indwelling catheter, residual urine volume and urinary retention rate of two groups were recorded, the bladder function was assessed by Mesure du handicap urinaire (MHU), the quality of life was evaluated by Functional Assessment of Cancer Therapy-Cervix (FACT-Cx).Results:There was no significant difference of the duration of indwelling catheter, residual urine volume and urinary retention rate between two groups ( P>0.05). After 3 months, the MUH scores were (1.91±0.79) points in the experiment group, lower than those in the control group (2.28±1.09) points; the social/family status, emotional status, additional interests scores and total FACT-Cx scores in experiment group were (24.58±1.97), (21.82±1.89), (40.95±2.63), (131.40±5.12) points, higher than those in the control group (23.40±2.79), (20.93±2.34), (39.51±2.77), (126.51±4.73) points, the differences were statistically significant ( t values were 2.052-5.259, P<0.05 or 0.01). Conclusions:Based on the pelvic floor training combine with Pilates exercise can help patients recover bladder function and promote quality of life of cervical cancer in young and middle-aged patients.

Alport syndrome, characterized by hematuria, renal failure, sensorineural deafness, and ocular abnormalities, is an inherited glomerular disease caused by mutations in the COL4A5 (X-linked), or COL4A3 and COL4A4 (autosomal recessive) genes.The ultrastructural changes of Alport syndrome can be observed in the electron microscopic analysis of renal biopsies, which are characterized by irregular thinning/thickening, layering and splitting dense layer of the glomerular basement membrane.In the basement membrane of skin and renal biopsy tissue, type IV collagen α chain immunofluorescence test can be used to diagnose Alport syndrome, screen the carriers and determine the mode of inheritance.The analysis and detection of Alport syndrome gene are not only useful for genetic counseling, but also useful for identification of gene carriers, prenatal diagnosis, and identification of suspected patients who can not be confirmed by clinical and pathological examination results.
