Objective To observe the effect of combining virtual reality technology with occupational thera-py in treating children with spastic hemiplegia resulting from cerebral palsy. Methods Thirty-eight spastic and hemiplegic children with cerebral palsy were randomly divided into a treatment group ( n=18) and a control group ( n=20) . Both groups received occupational therapy, while the treatment group was additionally provided with virtual reality-based treatment. The sessions lasted 30 min, 6 times a week for 3 months. Before and after the treatment the upper extremity motor function of both groups was assessed using the fine motor quotients of the Peabody developmen-tal motor scale, the Caroll hand function scale and a activities of daily life scale. Results Before the treatment there was no significant difference between the two groups in terms of any of the measurements. After the 3 months, significant improvement was observed in both groups, but the improvement of the treatment group was significantly greater than that of the control group. Conclusion Virtual reality technology can further improve the motor function of the upper ex-tremities and ability in the activities of daily life beyond that achievable through occupational therapy alone.

OBJECTIVE: To depict the cell landscape and molecular biological characteristics of human intrauterine adhesion (IUA) so as to better understand its immune microenvironment and provide new inspirations for clinical treatment. METHODS: Four patients with IUA who underwent hysteroscopic treatment at Dongguan Maternal and Child Health Care Hospital from February 2022 to April 2022 were selected as the study subjects. Hysteroscopy was used to collect the tissues of IUA, which were graded based on the patient's medical history, menstrual history and status of IUA. Library construction, sequencing, single cell data comparison and gene expression matrix construction were carried out in strict accordance with the single cell RNA sequencing process. Thereafter, the UMAP dimension reduction analysis of cell population and genetic analysis were carried out based on the cell types. RESULTS: A total of 27 511 cell transcripts were obtained from four moderately graded IUA tissue samples and assigned to six cell lineages including T cells, mononuclear phagocytes, epithelial cells, fibroblasts, endothelial cells and erythrocytes. Compared with normal uterine tissue cells, the four samples showed different cell distribution, and the proportions of mononuclear phagocytes and T cells in sample IUA0202204 were significantly increased, suggesting a strong cellular immune response. CONCLUSION The cell diversity and heterogeneity of moderate IUA tissues have been described. Each cell subgroup has unique molecular characteristics, which may provide new clues for further study of the pathogenesis of IUA and heterogeneity among the patients.
