Objective: To explore the association of latent profiles of mobile phone dependence and self control with physical exercise among junior high school students, so as to provide references for the prevention of mobile phone dependence and the improvement of self control among junior high school students. Methods: From April to May 2024, a stratified random cluster sampling method was used to select a total of 2 311 students from grade 7 to grade 9 in three public junior high schools in Xiangxi Autonomous Prefecture, Hunan Province. Latent profile analysis was conducted to identify the latent profiles of mobile phone dependence and self control among junior high school students. Pearson correlation analysis was used to examine the correlation between mobile phone dependence and self control, and Chi square test was used to analyze the distribution differences of latent profiles of adolescents across different demographic characteristics. Multiple Logistic regression analysis was applied to explore the association between mobile phone dependence, self control, and physical exercise. Results: Four latent profiles of mobile phone dependence and self control were identified: low dependence-moderate self control group ( n =885, 38.3%), moderate dependence-low self control group ( n =910, 39.4%), high dependence-no self control group ( n =232, 10.0%), and no dependence-high self control group ( n =284, 12.3%). Significant differences were observed in the distribution of latent profiles across gender, grade and only child status ( χ 2=10.85, 35.72, 13.85， P <0.05). Logistic regression analysis showed that, after controlling for demographic variables, compared with the low dependence-moderate self control group, physical exercise was negatively associated with the moderate dependence-low self control group ( OR =0.79) and the high dependence-no self control group ( OR =0.81), while positively associated with the no dependence-high self control group ( OR =1.58) ( P <0.01). Conclusions The influence of physical exercise on junior high school students different potential profile types of mobile phone dependence and self control is different. Schools and families should adopt targeted physical exercise interventions based on the characteristics of different profiles to promote the physical and mental health of junior high school students.

Objective: To analyze the heterogeneity of mobile phone dependence development trajectory in middle school students and its association with loneliness and selfcontrol ability, so as to provide reference for the prevention of mobile phone dependence in middle school students. Methods: A total of 941 grade 1 students from 4 public middle schools in Xiangxi Autonomous Prefecture, Hunan Province were selected for the followup survey by random cluster sampling from October 2023 to April 2024 and October 2024. Mobile Phone Addiction Index (MPAI), University of California, Los Angeles Loneliness Scale-20 (UCLA-20) and Selfcontrol Scales (SCS) were used for questionnaire survey. The heterogeneity of the developmental trajectory of middle school students mobile phone dependence was analyzed by the latent growth curve model (LGMM), and the influencing factors of the developmental trajectory of middle school students mobile phone dependence were explored by multiple Logistic regression analysis. Results: The development trajectory of middle school students mobile phone dependence could be divided into four categories: C1 "low risk slow decline group (n=438,44.6%)", C2 "medium risk slow rise group (n=272,29.7%)", C3 "high risk rapid decline group (n=73,8.6%)" and C4 "high risk rapid rise group (n=158,17.1%)". There were significant differences in the distribution of mobile phone dependence development track heterogeneity subgroups among sex, only child, lodging, and leftbehind students (χ2=117.79, 44.88, 37.09, 130.50, P <0.01). The results of the multinomial Logistic regression model analysis showed that, with C1 group as the reference, C2, C3, and C4 were positively correlated with students loneliness [OR(95%CI)=1.04 (1.02-1.06), 1.11(1.08-1.14), 1.12(1.09-1.14)]; C2 and C4 groups were negatively correlated with students selfcontrol [OR(95%CI)=0.97(0.96-0.99), 0.95(0.93-0.97)] (P<0.01). Conclusions The development trajectory of mobile phone dependence among middle school students is heterogeneous. Reducing the loneliness of individuals and cultivating good selfcontrol ability are helpful to alleviate mobile phone dependence behavior among middle school students.

Biliary atresia （BA） is characterized by progressive inflammation and fibrous obstruction of bile ducts， ultimately leading to cholestatic liver cirrhosis. Kasai surgery is the standard procedure for the treatment of BA， and early diagnosis is a key influencing factor for the prognosis of BA. Indocyanine green （ICG） is a near-infrared photosensitive dye that is efficiently and selectively absorbed by hepatocytes after intravenous injection， and it enters the intestine via bile and is excreted with the feces in the free form， with a favorable safety profile. In addition， ICG can emit fluorescence under near-infrared light， which can be captured by camera instruments and converted into visual images， and ICG fluorescence imaging technology can reflect the intraoperative situation in real time and significantly improve the success rate of the surgical procedure. This article reviews the advances in the application of ICG in early preoperative diagnosis， intraoperative imaging， and postoperative liver function assessment in recent years.

The proband was a 33-year-old pregnant woman (G4P1) who suffered spontaneous abortion in the first 3 months of pregnancy without a history of blood transfusion or transplantation. The fourth pregnancy was clinically diagnosed with threatened abortion, and a cesarean section was performed on June 28, 2023, at the Obstetrics and Gynecology Department of Dongguan Hospital of Traditional Chinese Medicine. During cross-matching tests, unexpected antibodies were detected in the proband′s plasma, which could not be specifically identified, and no suitable donor red blood cells could be found. The blood samples were sent to the Blood Transfusion Laboratory of Dongguan Blood Center. The laboratory used serology to identify the erythrocyte phenotype of the proband and confirmed the proband as having a rare p blood group. The unexpected antibody was identified as anti-PP1P K, and gene sequencing of the proband revealed that the new allele A4GALT* (c.100G>A+c.418_428delins) was homozygous, which is speculated to cause changes in the polypeptide chains p.Veral34ile and p.GERln140TRPFS *73, and inactivation of α1, 4-galactosyltransferase. At the same time, another new allele A4GALT*c.100G>A was found in family members, and it was predicted that the single change of p.Val34Ile caused by this mutation would not affect protein function or enzyme activity.

【Objective】 To estimate the prevalence, associated factors and patterns of multimorbidity of non-communicable diseases among adults in Shaanxi Province so as to provide evidence for the prevention and control of non-communicable diseases. 【Methods】 We used the data of adults aged 18 years and older collected in the baseline survey of Shaanxi Project in the Regional Ethnic Cohort Study in Northwest China. Multinomial logistic regression was used to explore the associated factors for multimorbidity. Exploratory factor analysis was used to extract patterns of multimorbidity. 【Results】 The prevalence of multimorbidity was 10.7% among the 44 442 participants. Age increase, being males, urban residence, and being overweight or obesity were positively associated with multimorbidity. Compared with women, men had a higher risk of multimorbidity. The OR and 95% CI was 1.25 (1.12-1.39). The risk of multimorbidity increased with age among adults. Compared with participants aged 18.0-34.9 years, the ORs and 95% CIs of those aged 35.0-44.9, 45.0-54.9, 55.0-64.9, and ≥65.0 years were 4.73 (3.47-6.46), 15.61 (11.60-21.00), 41.39 (30.76-55.70) and 90.04 (66.58-121.77), respectively. The primary multimorbidity patterns among adults in Shaanxi were cardiovascular-metabolic multimorbidity (5.4%), viscero-articular multimorbidity (1.0%), and respiratory multimorbidity (0.3%). 【Conclusion】 More than one in ten adults in Shaanxi Province had multimorbidity, and the predominant pattern of multimorbidity was cardiovascular-metabolic multimorbidity. The prevention and control of non-communicable diseases should be reinforced in middle-aged and older people, males, people living in the urban, and overweight or obese people. More attention should be paid to the prevention and control of cardiovascular-metabolic diseases.

Parvalbumin interneurons belong to the major types of GABAergic interneurons. Although the distribution and pathological alterations of parvalbumin interneuron somata have been widely studied, the distribution and vulnerability of the neurites and fibers extending from parvalbumin interneurons have not been detailly interrogated. Through the Cre recombinase-reporter system, we visualized parvalbumin-positive fibers and thoroughly investigated their spatial distribution in the mouse brain. We found that parvalbumin fibers are widely distributed in the brain with specific morphological characteristics in different regions, among which the cortex and thalamus exhibited the most intense parvalbumin signals. In regions such as the striatum and optic tract, even long-range thick parvalbumin projections were detected. Furthermore, in mouse models of temporal lobe epilepsy and Parkinson's disease, parvalbumin fibers suffered both massive and subtle morphological alterations. Our study provides an overview of parvalbumin fibers in the brain and emphasizes the potential pathological implications of parvalbumin fiber alterations.

Sialidosis is a rare autosomal recessive disorder which is classified into type Ⅰ and Ⅱ according to the age of onset and severity of the disease.Type I,also known as mucolipidosis,is often manifested as myoclonus,ataxia,general tonic clonic seizure,and bilateral cherry-red spots in eye examination.Four cases of type Ⅰ sialidosis were reported in order to improve the diagnosis and treatment of this disease.Patients were mainly manifested as myoclonus and ataxia.Whole exon gene sequencing of the four patients all showed the mutation c.544A＞G in the NEU1 gene.Meanwhile,the new mutation c.596G＞A carried was found in case 2 and its pathogenicity was also analyzed.Finally,we summarized the clinical characteristics of type Ⅰ patients in China,noting that most patients develop all the core symptoms as the disease progresses.

Objective: To investigate the quality of life among patients with occupational pneumoconiosis in Jinhua City, Zhejiang Province, so as to provide insights into improving the quality of life among patients with occupational pneumoconiosis. Methods: Patients with occupational pneumoconiosis in Jinhua City from 2009 to 2021 were retrieved from the National Occupational Disease and Health Risk Factors Monitoring Information System. Participants' demographics, diagnosis of pneumoconiosis, stage of pneumoconiosis, pulmonary function and medical expense were collected through questionnaire surveys, and the quality of life was measured using a Chinese version of the Short-Form Health Survey (SF-36). The quality of life was descriptively analyzed among patients with occupational pneumoconiosis by disease stage, pulmonary function, expense for disease diagnosis and treatment and educational level. Results: A total of 244 patients with occupational pneumoconiosis were enrolled, including 225 men (92.21%). The participants had a mean age of (75.20±9.42) years, and mean duration from dust contact to pneumoconiosis onset of (13.11±9.89) years. The scores for physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role-emotional, and mental health were (64.03±31.22), (45.14±44.22), (56.34±26.60), (40.80±19.80), (59.14±17.35), (68.41±19.67), (47.03±44.08) and (61.15±17.06) points among patients with occupational pneumoconiosis, which were all lower than the national constant (P<0.05). Lower scores were measured for physical functioning [(31.17±23.40) points], bodily pain [(45.21±19.50) points] and vitality [(47.00±20.70) points] among patients with stage Ⅲ occupational pneumoconiosis, for physical functioning [(32.27±24.24) points], role-physical [(12.88±30.70) points], bodily pain [(37.44±20.43) points], general health [(14.76±17.17) points], vitality [(38.79±19.33) points], social functioning [(53.33±17.08) points], role-emotional [(9.09±26.71) points], and mental health [(53.21±17.25) points] among occupational pneumoconiosis patients with severe pulmonary function damages, and for physical functioning [(30.97±27.40) points], bodily pain [(37.77±24.34) points], general health [(19.10±18.62) points], vitality [(38.39±23.78) points], social functioning [(55.89±21.00) points] and mental health [(55.35±20.35) points] among occupational pneumoconiosis patients that had personal payments for pneumoconiosis diagnosis and treatment expenses exceeding 30% of annual household incomes, while higher scores were measured for physical functioning [(66.36±17.33) points] and role-physical [(59.09±45.10) points] among occupational pneumoconiosis patients with an educational level of high school and above (all P<0.05). Conclusions The quality of life was low among occupational pneumoconiosis patients in Jinhua City from 2009 to 2021. Stage of pneumoconiosis, pulmonary function, medical expenses and educational level were identified as factors affecting the quality of life among occupational pneumoconiosis patients in Jinhua City.
