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.

Objective: To under the prevalence of malnutrition and its associated factors in school aged children with cerebral palsy, so as to provide a basis for relevant departments to formulate targeted policies. Methods: From July to August 2023, the researchers selected 333 children with cerebral palsy and 960 children with other diseases aged 6-18 years who were residents of a social welfare institution in Guangzhou, China. Their height and weight were measured and a nutritional status analysis was carried out using a cluster sampling method. Multivariate Logistic analysis was performed to analyze the relative factors and malnutrition status of school aged children with cerebral palsy. Results: The prevalence of growth retardation among school aged children with cerebral palsy was 74.5%, with rates of stunting, normal nutrition status, and overweight/obesity being 17.7%, 7.2%, and 0.6%, respectively. The results of the univariate analysis revealed statistically significant differences in the detection rate of malnutrition among school aged children with cerebral palsy based on gender, gross motor function classification system (GMFCS) grading, and the presence of swallowing disorders ( χ 2=6.02, 15.23, 32.16, P <0.05). The results of the multivariate Logistic regression analysis showed that gender ( OR=0.37, 95%CI =0.15-0.91), dysphagia (OR=4.10, 95%CI =1.39-12.12), and GMFCS classification ( OR=1.45, 95%CI =1.04-3.01) were influencing factors of malnutrition ( P <0.05). Conclusions The detection rate of malnutrition among children and adolescents with cerebral palsy in welfare institutions was found to be relatively high, and influenced by various factors. Corresponding nutritional interventions should be developed and implemented based on the risk factors of malnutrition in school aged children with cerebral palsy to improve their nutritional status.

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.

ObjectiveTo carry out an epidemiological analysis on an outbreak of Mycoplasma pneumoniae infection at a welfare institution to provide a theoretical basis for the corresponding prevention and control measures. MethodsUsing the method of field epidemiological investigation， special field treatment was carried out in September 2022. Serum samples from cases and close contacts in the same ward area were collected for detection of nine respiratory tract infection pathogens （Mycoplasma pneumoniae， chlamydia， influenza， human metapneumosis， respiratory syncytial， human boca， parainfluenza type 1‒4 virus， and Middle East respiratory syndrome， severe acute respiratory syndrome coronavirus） by immunofluorescence immunoglobulin M （IgM） antibody test. ResultsA total of 14 Mycoplasma pneumoniae cases were identified， all of whom were residents of the welfare institution. The first case occurred on September 4， while the last case was reported on September 13. The incidence rate of the fifth ward area where the first case reported was 12.82% （10/78）， and it was 3.57% （3/84） in the third ward area and 1.20% （1/83） in the first ward area. There was a significant difference in incidence rates between ward areas （χ²=8.90， P<0.05）， but no significant difference was observed in age distribution and length of hospitalization. Thirty-three samples were collected for detection of nine kinds of IgM antibodies against respiratory pathogens. The results showed that the Mycoplasma pneumoniae IgM antibody was weakly positive in the 14 cases. ConclusionBased on the epidemiological history， clinical symptoms and laboratory tests， it was concluded that it was an outbreak of Mycoplasma pneumoniae infection within the welfare institution. Welfare institutions should continue to control the occurrence and outbreak of infection through effective routine hygiene， ventilation， and disinfection so as to ensure the health and safety of their clients.

Objective:To compare the efficacy and safety of low-dose and standard-dose radiotherapy (LD-RT vs. SD-RT) in the treatment of oropharyngeal cancer patients with positive human papillomavirus (HPV). Methods:All comparative studies of low-dose versus standard-dose radiotherapy in the treatment of HPV-positive oropharyngeal cancer were searched from PubMed, Web of Science, Cochrane Library, EMbase, Chinese Biomedical Literature Database (CBM), CNKI, Chongqing VIP, and Wanfang databases from January 1, 2000 to February 9, 2023. According to the inclusion and exclusion criteria, the data were strictly screened, and the RevMan 5.4 software was used for meta-analysis.Results:A total of 8 studies were included. The pooled results showed that the overall survival (OS) and progression-free survival (PFS) of patients in the LD-RT group were similar to those in the SD-RT group ( HR=0.83, 95% CI=0.59-1.18, P=0.31; HR=0.97, 95% CI=0.53-1.78, P=0.92), but the rate of percutaneous endoscopic gastrostomy (PEG) insertion was significantly reduced ( RR=0.45, 95% CI=0.28-0.72, P=0.001). Conclusion:LD-RT yields similar efficacy and lower rate of PEG insertion compared with SD-RT in HPV-positive oropharyngeal neoplasm patients.

Objective:To analyze the clinical phenotype and genetic characteristics of probands in 3 pedigrees of complex hereditary spastic paraplegia type 5 (HSP5) who developed symptoms during childhood, and the genetic diagnostic methods of HSP5 to improve the diagnosis and differential diagnosis of this disease.Methods:The clinical data of 3 HSP5 families admitted to Henan Provincial People′s Hospital from June 2020 to January 2023 were collected. Whole exome sequencing (WES) was performed on the patients to analyze phenotype-related single nucleotide variation (SNV) and small fragment insertion/deletion (INDEL) variation. At the same time, the sequencing data were used to analyze the dynamic mutation regions of specific genes.Results:The probands in the 3 families had complex HSP: the proband in family 1 showed weakness of both lower limbs, urgency of urination and ataxia; the proband in family 2 showed slightly lower intelligence, weakness of both lower limbs, dysarthria, and brain magnetic resonance imaging showed white matter lesions; the proband in family 3 showed muscle weakness, spasm, frequent urination and ataxia of both lower limbs. The sequencing results showed that the CYP7B1 gene c.1171G>T (paternal) and c.1249C>T (maternal) compound heterozygous mutations were found in proband 1 and his younger brother. The CYP7B1 gene c.334C>T (paternal) and c.259+2T>C (maternal) compound heterozygous mutations were found in proband 2 and her younger sister. The CYP7B1 gene c.334C>T (paternal) and c.1082G>A (maternal) compound heterozygous mutations were found in proband 3. And c.1171G>T was a new variant that had not been reported before. Dynamic mutation analysis showed that the numbers of CAG repeats of ATXN1/2/3/6/7/8/12, DRPLA, TBP genes were within the normal range. According to the clinical manifestations and genetic examination results of the children in the 3 pedigrees, the diagnosis of HSP5 was clear. Conclusions:The 3 families in the study all had complex HSP5 caused by compound heterozygous mutations of the CYP7B1 gene. WES can analyze SNV, INDEL and dynamic mutations simultaneously to make the maximum clear diagnosis and can be used as an effective detection method for HSP5.

Frontotemporal dementia (FTD) is a group of dementia diseases mainly characterized by progressive mental-behavioral abnormalities, executive dysfunction, and language impairment. A small number of FTD patients also present with movement disorders at certain disease course. Here the clinical and multimodal positron-emission tomography (PET) imaging manifestations in a patient with frontotemporal lobe dementia and parkinsonian syndrome are reported. 18F-fluorodopa PET showed reduced uptake in the head of the caudate nucleus. 18F-AV-45 PET showed negative amyloid deposition. 18F-AV-1451 PET showed tau deposition in the neocortex. The clinical and neuroimaging features support the underlying frontotemporal lobar degeneration-tau pathology.

OBJECTIVE: To explore the clinical characteristics and genetic variants in a patient with adult ceroid lipofuscinosis neuronal type 7 (ACLN7). METHODS: A female patient diagnosed with ACLN7 in Henan Provincial People's Hospital in June 2021 was selected as the study subject. Clinical data, auxiliary examination and result of genetic testing were retrospectively analyzed. RESULTS: The patient, a 39-year-old female, has mainly presented progressive visual loss, epilepsy, cerebellar ataxia and mild cognitive decline. Neuroimaging analysis has revealed generalized brain atrophy, prominently cerebellum. Fundus photography has revealed retinitis pigmentosa. Ultrastructural skin examination has revealed granular lipofuscin deposits in the periglandular interstitial cells. Whole exome sequencing revealed that she has harbored compound heterozygous variants of the MSFD8 gene, namely c.1444C>T (p.R482*) and c.104G>A (p.R35Q). Among these, c.1444C>T (p.R482*) was a well established pathogenic variant, while c.104G>A (p.R35Q) was a missense variant unreported previously. Sanger sequencing confirmed that the daughter, son and elder brother of the proband have respectively carried heterozygous c.1444C>T (p.R482*), c.104G>A (p.R35Q), and c.104G>A (p.R35Q) variants of the same gene. The family has therefore fit with the autosomal recessive inheritance pattern of the CLN7. CONCLUSION Compared with previously reported cases, this patient has the latest onset of the disease with a non-lethal phenotype. Her clinical features have involved multiple systems. Cerebellar atrophy and fundus photography may be indicative of the diagnosis. The c.1444C>T (p.R482*) and c.104G>A (p.R35Q) compound heterozygous variants of the MFSD8 gene probably underlay the pathogenesis in this patient.
