Objective To study intervention effect of diet habits according to Trans-theoretic Model (TTM) in young and middle-aged patients with asymptomatic hyperuricemia. Methods 120 patients were divided into the intervention group (n=60) and the control group (n=60). The nursing intervention by stages of TTM was implemented to a total of 56 patients in the intervention group in the study. Routine nursing care was taken to 57 patients in the control group. Patients were evaluated by self-designed questionnaire after 1, 3 and 6 months of the intervention in the two groups respectively, including the diets of patients, the change of patients′ eating habit, differences of uric acid, total cholesterol, triglycerides, blood sugar. Results The patients′ intake of beer, seafood, meat, edible oil in the intervention group was lower than the patients′ intake in the control group, while the patients′ intake of fruits and vegetables was higher than the patients′intake in the control group after 1, 3 and 6 months of the intervention, which was statistically significant ( P < 0.01). Compared with 27 cases in the control group, 53 cases in the intervention group were in action phase and maintenance phase after 6-month intervention, the difference was statistically significant (P < 0.01). After six months′intervention, the patients′uric acid, triglycerides in the intervention group was (418.01 ± 24.15)μmol/L and (1.52 ± 0.56) mmol/ L respectively, which was significantly lower than (435.02 ± 26.35) μmol/ L and (2.45 ± 0.74) mmol/L in the control group, t values were-3.47 and 2.20 respectively, P<0.01. Conclusions Diet intervention based on the TTM can effectively promote the change of patients′ unhealthy eating habits, improve self-management skills, and reduce uric acid, which is worthy of generalizing.

Objective To explore the relationship between the timing of functional training and its therapeutic effects on patients with cerebral infarction. Methods One hundred and fifty-six patients with cerebral infarction of internal carotid artery system were randomly and equally divided into three groups (groups A, B and C), and the functional training was initiated within 7d, 7～30d or over 30d after cerebral infarction in groups A, B, C, respectively. The effects were evaluated at 91d after the functional training. Results Compared with those of group C, the therapeutic effects in groups A and B were significantly better (P

Objective To evaluate the value of monitoring circular blood interleukin(IL)-17 for predicting 60 d mortality rate in premature infants with necrotizing enterocolitis(NEC).Methods A total of 85 neonates with surgically or medically treated NEC were retrospectively included.Serum IL-17 level was detected in diagnosing NEC and before preparing operation for evaluating its predictive value.Results The mortality rate after 60 d was 20 ％ (17/85),in which 5 (10 ％)was in the medical treatment group and 12(34％) in the surgical treatment group.The IL-17 level was significantly correlated with mortality rate after 30 d [odds ratio (OR):1.38;CI:1.14-1.67;P=0.001].The preoperative IL-17 level in the surgical treatment group was 27-7 500 pg/mL(median 2 625 pg/mL),which was significantly higher than mean 156 pg/mL in the medical treatment group.The difference in the area under curve(AUC)between the medical treatment group and surgical treatment group was 0.82(CI:0.74-0.90).The critical value of IL-17 for detection significance was 1 783 pg/mL(sensitivity was 90.5％,specificity was 59.2％).Conclusion Serum IL-17 level is correlated with the mortality rate after 60 d.

Objective To observe the effects of family cognitive training on patients with vascular cognitive impairment but without dementia.Methods Sixty patients with non-dementia type vascular cognitive impairment were divided at random into a group which received family cognitive training (30 cases) and a control group (30 cases).The 2 groups all took routine drugs and exercise.The family cognitive training group received cognitive training additionally.Before treatment and after 1 and 6 months of treatment,all of the patients of both groups were assessed using the mini-mental state examination (MMSE),the Montreal cognitive assessment (MoCA) and the modified Barthel index (MBI).Results After 1 month of treatment there was no significant difference between the 2 groups in any of the assessments.After6 months the scores on each item of the MMSE,MoCA and MBI had improved significantly more in the family cognitive training group than in the control group.Conclusion Family cognitive training is effective in treating non-dementia type vascular cognitive impairment.It can delay disease progression and improve cognitive function and ability in the activities of daily living.

Objective To explore the clinical features of mitochondrial encephalomyopathy lactic acidosis and strokelike episodes (MELAS) syndrome in fratemal twins brothers.Methods The clinical data,the results of laboratory examinations,electroencephalogram (EEG),imaging,and gene detection,and the process of diagnosis and treatment were retrospectively analyzed the fraternal twin brothers with MELAS syndrome.Results The proband,a 7-year-old male,had intermittent headaches,vomit and twitching at onset.He suffered from exercise intolerance,fatigue,accompanied by short stature and hairy.The fasting blood lactic acid level was increased.Multiple video EEG showed the slowdown of background activity.Head MRI showed recurrent lesions with the characteristics of migration and variation.The point mutation rate of mtDNA A3243G was 34.7％.The diagnosis of MELAS was confirmed.At the same time,his fraternal twin brother was screened and found that his point mutation rate of A3243G was 30.0％.Although there was no clinical symptom at that time,he was onset with convulsion after 3 years.Conclusions Gene detection and family screening are helpful for the early diagnosis of MELAS.The mutation rate of A3243G is very high,which can cause an early onset and serious clinical symptoms.

OBJECTIVE: To explore the clinical features and genetic etiology of a child with Multiple congenital malformations-hypotonia-epilepsy syndrome type 3 (MCAHS3) and provide prenatal diagnosis for her parents. METHODS: A female child who had presented at Linyi People's Hospital on 27 July 2022 for recurrent convulsions for over 4 years was selected as the study subject. Clinical data of the child were collected. Peripheral blood samples were taken from the child and her parents and subjected for whole exome sequencing (WES). Candidate variants were verified by Sanger sequencing. Prenatal diagnosis was carried out on amniotic fluid sample at 18 weeks' gestation. Bioinformatic software was used to analyze the pathogenicity of the protein model for the variant loci. RESULTS: The child was a 4-year-old female with frequent seizures, peculiar facial appearance, hypotonia and severe developmental delay. Genetic analysis revealed that she has harbored compound heterozygous variants of the PIGT gene, namely c.1126del (p.H376Tfs*56) and c.1285G>C (p.E429Q), which were respectively inherited from her mother and father. Based on the guidelines from the American College of Medical Genetics and Genomics, the c.1126del (p.H376Tfs*56) variant was predicted to be pathogenic (PVS1+PM2_Supporting+PM4), and c.1285G>C (p.E429Q) variant was predicted to be likely pathogenic (PM2_Supporting+PM3+PM4). Prenatal diagnosis suggested that the fetus also harbored the same compound heterozygous variants, and the pregnancy was terminated with induced labor. CONCLUSION The c.1126del (p.H376Tfs*56) and c.1285G>C (p.E429Q) compound heterozygous variants of the PIGT gene probably underlay the MCAHS3 in this patient, and prenatal diagnosis has prevented birth of further affected child in this family.

Objective:To analyze the clinical phenotypes and TSC1/TSC2 gene variations in 52 children with tuberous sclerosis complex. Methods:The clinical data of 59 children with tuberous sclerosis complex hospitalized in Linyi People′s Hospital between January 2017 and October 2022 were collected. The analysis of TSC1 and TSC2 gene variations on main family members was performed, and then bioinformatics analysis followed. The positive children were divided into TSC1 gene group and TSC2 gene group, and the difference of clinical characteristics between the two groups was analyzed. Results:Among 59 children, 52 cases were detected TSC1/ TSC2 gene variations (17 cases in the TSC1 gene group and 35 cases in the TSC2 gene group). Of the 52 children, 28 (53.8%) were male, 24 were female (46.2%); 17 (32.7%) were familial cases (10 with TSC1 gene variations and 7 with TSC2 gene variations), 35 (67.3%) were sporadic cases; 46 (88.5%) had hypomelanotic macules, 13 (25.0%) had facial angiofibromas, 5 (9.6%) had shagreen patches, 49 (94.2%) had subependymal nodules/calcifications, 47 (90.4%) had cortical nodules, 2 (3.8%) had subependymal giant cell astrocytomas, 39 (75.0%) had intellectual/developmental disabilities, 49 (94.2%) had epileptic seizures, 8 (15.4%) had cardiac rhabdomyomas, 9 (17.3%) had renal angiomyolipomas, and 4 (7.7%) had retinal hamartomas. Of the 52 children, 49 variations were detected, including 4 large fragment deletion/duplication variations, and 45 point variations; 41 pathogenic variations, 7 likely pathogenic variations, and 1 variation of uncertain significance. In this study, 16 point mutations and 1 large fragment duplication mutation which had not been reported at home and abroad, and 3 high-frequency mutation sites (p.Arg692 *, p.Arg228 *, and p.Arg1200Try) were found. There was a statistically significant difference in the proportion of familial cases [10/17 vs 7/35(20%), χ2=7.838, P=0.005], median onset age of epilepsy [38.0(0.5-134.0) months vs 8.0(0.1-63.0) months, Z=3.506 , P<0.001] and the incidence of developmental retardation/intellectual impairment [8/17 vs 31/35(88.6%), χadj2=8.423, P=0.004] between the TSC1 gene and TSC2 gene groups. Conclusions:Tuberous sclerosis compiex has widespread phenotypes, can affect every body system, especially the skin and nervous system. The pathogenic gene is TSC1/ TSC2. The TSC1 gene group has more familial cases. The TSC2 gene group has an earlier onset age of epilepsy and a higher incidence of developmental retardation/intellectual impairment. In this study, 16 novel point mutations, 1 novel large fragment duplication mutation, and 3 hotspot mutations were identified, expanding the gene variation spectrum of tuberous sclerosis complex.

Objective:To explore the clinical features and genetic etiology of a child with SPONASTRIME dysplasia (SD).Methods:A 9-month-old female who had presented at the Linyi People′s Hospital in August 2022 for short stature was selected as the study subject. Clinical data of the child were collected, and whole exome sequencing (WES) was carried out. Sanger sequencing was used for validating the candidate variants.Results:The child has manifested short stature, mid-face hypoplasia, joint laxity, internal knee rotation, irregularities in the metaphysis of long bones, and flat and concave lumbar vertebrae. WES revealed that she has harbored compound heterozygous variants of the TONSL gene, namely c.3088G>T (p.Glu1030*) and c. 3053G>A (p.Arg1018His), which were inherited from her phenotypically normal parents. Neither variant was reported previously. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the c. 3088G>T variant was classified as likely pathogenic (PVS1+ PM2_Supporting), whilst the c. 3053G>A was classified as a variant of uncertain significance (PM2_Supporting+ PM3+ PP3). Conclusion:The c. 3088G>T and c. 3053G>A compound heterozygous variants of the TONSL gene probably underlay the pathogenesis in this patient. Above finding has facilitated the clinical diagnosis and genetic counseling for her family.

Objective:To analyze the clinical phenotype and gene sequencing results of a child with hyperekplexia, and to clarify her genetic etiology.Methods:The clinical information of the child was collected, and the whole exome sequencing of the child and her parents was performed. The suspected pathogenic variants were verified by Sanger sequencing and bioinformatics analysis.Results:There was a 12 years old girl, who was hospitalized in the Department of Pediatric Neurology of Linyi People′s Hospital because of "paroxysmal limb stiffness for more than 11 years and aggravated for half a month" on July 4, 2022. The girl showed exaggerated startle reflexes and generalized siffness in response to external sudden, unexpected stimuli, occasionally accompanied by apnea and cyanosis, frequent attacks occurred several times a day, lasting for 1-30 minutes, and early head and abdomen flexion can be relieved. She showed normal growth and development, no abnormality in brain magnetic resonance imaging and video electroencephalogram during seizure. The whole exome sequencing showed that there was a missense heterozygous mutation c.643T>C(p.W215R) in the SLC6A5 gene of the child. Neither of the parents carried this mutation, which was a novel and de novo variant. According to the guidelines of American College of Medical Genetics and Genomics, this variant was a likely pathogenic variant [PS2: de novo (both maternity and paternity confirmed) in the patient with the disease and no family history; PM2: undetected variants in the normal population; PP3: multiple softwares predicted that this mutation would have harmful effects on genes or gene products], and highly conserved. Swiss modeling found that the hydrogen bond of the modified amino acid also changed. Conclusions:Hyperekplexia is relatively rare and prone to misdiagnosis. The main clinical features are excessive startle reflexes (limb shaking, or jumping) to unexpected external stimuli, resulting in overall stiffness, normal growth and development, and normal video electroencephalogram during the seizure. The likely pathogenic heterozygous missense variant c.643T>C (p.W215R) of SLC6A5 gene is the genetic cause of this case.

Objective:To analyze the clinical characteristics of a child with developmental epileptic encephalopathy caused by NR4A2 gene mutation, and to summarize the clinical phenotypes and genotypes to improve the clinician′s understanding of this disease. Methods:The clinical data of a child with developmental epileptic encephalopathy admitted to Linyi People′s Hospital in August 2022 were collected, video electroencephalogram, craniocerebral magnetic resonance imaging and family whole exon sequencing were improved, and the suspected mutation sites were verified by Sanger sequencing. Relevant literature was consulted to summarize the clinical phenotypes and genetic characteristics of nervous system diseases caused by NR4A2 gene. Results:It was found that there was a heterozygous missense mutation at the locus c.866G>A (p.A289H) of NR4A2 gene in the child, which was a de novo mutation, and both parents were wild type. According to the American Society of Medical Genetics and Genomics variation classification, it was assessed as a suspected pathogenic variation. Through literature review, there were 16 related cases reported internationally, with clinical phenotypes including mental retardation/mental retardation, language disorders, seizures, muscle tone changes and different psychological and behavioral problems. Conclusions:The NR4A2 gene is not only associated with dopa responsive disorders, but also with neurological development, intellectual impairment, language development delay, and epilepsy. The mutation of NR42A gene c.866G>A (p.A289H) is the genetic cause of the patient, and the detection of this locus expands the NR4A2 gene spectrum. NR4A2 gene is one of the pathogenic genes of developmental epileptic encephalopathy.
