ObjectiveTo investigate the associations of multiple glycolipid metabolic indicators and their cumulative abnormality burden with incident colorectal cancer risk in a general population-based prospective cohort, and to examine the mediating role of glycolipid metabolic abnormalities in the relationships between smoking, alcohol consumption, physical activity, and colorectal cancer incidence. MethodsA total of 17 897 eligible participants recruited from the Taizhou Cohort between 2011 and 2014 were included. Cox proportional hazards regression models were used to assess the associations of conventional and derived glycolipid indicators, as well as a glycolipid abnormality index constructed from total cholesterol, triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, fasting plasma glucose, and insulin, with incident colorectal cancer risk. Restricted cubic spline models were applied to evaluate dose-response relationships for major indicators. Receiver operating characteristic curves were generated to compare predictive performance across indicators. Mediation analyses were conducted to assess the mediating effects of the glycolipid abnormality index on the associations of smoking, alcohol consumption, and physical activity with colorectal cancer incidence. ResultsDuring a median follow-up of 11.2 years, 102 incident colorectal cancer cases were identified, with an incidence density of 51.2 per 100 000 person-years. After adjustment for potential confounders, Cox proportional hazards regression analyses showed that decreased high-density lipoprotein cholesterol was associated with a 1.74-fold higher risk of colorectal cancer (HR=1.74, 95%CI: 1.03‒2.95), elevated low-density lipoprotein cholesterol was associated with a 1.78-fold higher risk (HR=1.78, 95%CI: 1.05‒3.02), and abnormal fasting plasma glucose was associated with a 1.86-fold higher risk (HR=1.86, 95%CI: 1.15‒3.02). Triglycerides and fasting plasma glucose showed an approximately linear increasing association with colorectal cancer risk in multivariable restricted cubic spline models. The glycolipid abnormality index showed a clear gradient association with colorectal cancer risk; participants with three or more abnormal indicators had a 3.08-fold higher risk than those without abnormalities (HR=3.08, 95%CI: 1.60‒5.92). The area under the curve was 0.795, higher than that of individual glycolipid indicators and other combined indices, and gender-stratified analyses showed generally consistent patterns. Glycolipid metabolic abnormalities partially mediated the associations of smoking, alcohol consumption, and physical activity with colorectal cancer incidence, with mediation proportions of 8.33%, 9.45%, and 9.04%, respectively. ConclusionGlycolipid metabolic abnormalities are associated with an increased risk of incident colorectal cancer. The glycolipid abnormality index shows an increasing relationship with colorectal cancer risk and demonstrates better discrimination, and it partially mediates the associations of smoking, alcohol consumption, and physical activity with colorectal cancer incidence in the overall population.

Objective:To apply combined serological diagnostic methods for anti-BP180-type and anti-laminin 332 (Ln332) -type mucous membrane pemphigoid (MMP), and to summarize their clinical and immunoserological characteristics.Methods:A retrospective analysis was conducted on the data from 52 patients clinically suspected of having MMP at the Hospital of Dermatology, Chinese Academy of Medical Sciences from January 2017 to February 2022. Serum samples were collected, and combined serological tests, including indirect immunofluorescence on salt-split skin, enzyme-linked immunosorbent assay, and immunoblotting, were performed to analyze the immunoserological and clinical characteristics of the patients. The Fisher′s exact test was used to compare the lesion occurrence rates between groups.Results:Among the 52 patients clinically suspected of MMP, 32 (61.5%) were diagnosed with anti-BP180-type MMP, 10 (19.2%) with anti-Ln332-type MMP, and 4 (7.7%) with anti-BP180- and anti-Ln332-type MMP due to the presence of both anti-BP180 and anti-Ln332 antibodies; 2 tested positive for IgG on the epidermal side of salt-split skin, but no target antigens were identified by serological tests, and they were diagnosed with MMP (subtype pending) ; 4 tested negative by immunoserological tests. Ocular involvement was observed in 6 out of 10 patients with anti-Ln332-type MMP, whereas only 6 out of 32 anti-BP180-type MMP patients (18.8%) had ocular symptoms, and there was a significant difference in the occurrence rate of ocular involvement between the two groups ( P = 0.02) ; the occurrence rates of nasal involvement and multi-mucosal involvement were significantly higher in the anti-Ln332-type MMP patients (50%[5/10], 90%[9/10], respectively) than in the anti-BP180-type MMP patients (0, 25%[8/32], respectively, both P < 0.001). Scar formation occurred in 6 out of 10 anti-Ln332-type MMP patients, but occurred in only 6 out of 32 anti-BP180-type patients (18.8%, P = 0.02) . Conclusion:The combination of indirect immunofluorescence on salt-split skin, enzyme-linked immunosorbent assay, and immunoblotting could effectively identify anti-BP180 and anti-Ln332 autoantibodies in MMP patients, with BP180 being the most common target antigen; compared with anti-BP180-type MMP, anti-Ln332-type MMP appeared to be more frequently involve the ocular and nasal mucosae, associated with the involvement of multiple mucosal sites, carrying a higher risk of scar formation.

Traumatic main bronchus rupture is a relatively rare injury in thoracic trauma, which is extremely critical, with a mortality rate as high as 70% - 80%. The complete rupture and displacement of the traumatic cervical trachea can lead to asphyxia, hypoxia, and cardiac arrest, even death of the patient in a short time. We performed emergency surgery with the support of extracorporeal membrane oxygenation for a case of traumatic cervical tracheal trunk complete rupture and displacement combined with cardiac arrest and achieved a successful rescue. We summarized our experience and found that timely surgical reconstruction of the airway is the key to increasing the traumatic main bronchus rupture survival of patients.

OBJECTIVES: To investigate the clinical features and gene mutation characteristics of combined oxidative phosphorylation deficiency type 7 (COXPD7) caused by mutations in the C12orf65 gene, and to enhance the awareness of this disease. METHODS: A child diagnosed with COXPD7 in the Department of Neurology, Children's Hospital Affiliated to Zhengzhou University in 2021 was included, along with 10 patients reported in the literature. All subjects were analyzed for their genotypes and clinical phenotypes. RESULTS: A total of 11 patients with COXPD7 were included, comprising 1 reported in this study and 10 from the literature. Among the 11 patients, 9 had homozygous mutations in the C12orf65 gene, while 2 had compound heterozygous mutations, which were identified as frameshift or nonsense mutations. The age of onset ranged from 1 day to 2 years, and clinical manifestations included optic nerve atrophy and delays in intellectual and motor development. Eight patients exhibited external ophthalmoplegia, and five patients displayed spastic paralysis. Cranial magnetic resonance imaging revealed optic nerve atrophy in all 11 patients, abnormal brainstem signals in 10 patients, and a lactate peak on brainstem magnetic resonance spectroscopy scans in 3 patients. CONCLUSIONS COXPD7 associated with the C12orf65 gene results from homozygous or compound heterozygous mutations, with primary clinical manifestations of optic nerve atrophy and delays in intellectual and motor development. Some patients may also present with spastic paralysis or external ophthalmoplegia. Cranial imaging reveals symmetrical abnormal signals in bilateral basal ganglia and brainstem, and a lactate peak is observed on brainstem magnetic resonance spectroscopy scans.

Objective:To analyze the etiological features and clinical characteristics of herpes zoster cases under 20 years old in Beijing City from 2017 to 2021.Methods:Herpes zoster cases were collected from a surveillance system in Beijing City from December 2017 to April 2021. The cases included individuals under 20 years old from seven sentinel hospitals located in two districts (Miyun District and Changping District). The basic information, the rash date of rash onset and the location and number of lesions were investigated at the first visit to the hospital, and the lesion swab samples were collected for laboratory testing. A telephone follow-up was conducted 21 days after the onset of the rash to investigate the degree of pain, duration of the rash and duration of pain. The individuals who still experienced neuralgia were further investigated for their pain condition at 90 days after the onset of the rash, to discover cases with postherpetic neuralgia. DNA was extracted from the rash fluid, and the ORF62 gene region was amplified and sequenced to obtain the viral sequence. The wild-type strain or chickenpox vaccine strain was identified by using sequence alignment, and the clinical characteristics of cases with different varicella vaccinations were compared.Results:A total of 78 herpes zoster cases under 20 years old were investigated during 2017-2021 in Beijing City, and 61 cases completed the follow-up survey. The age range of 61 cases was 1.83 to 20.54 years with a median age of 17.50 years. There were 36 males (59.02%) and 25 females (40.98%). Among them, there were 29 cases with the chickenpox vaccine immunization history (18 cases with one dose, 5 cases with two doses and 6 cases with unknown doses), 13 cases with no vaccination history and 19 cases with unknown vaccination history. Among the 78 cases, the herpetic fluid samples of 64 cases were positive for VZV, including 62 cases identified as wild-type strains and two cases as vaccine strains. The two vaccine strain cases were both 2-year-old girls who had received one dose of varicella vaccine and developed herpes zoster 3 months and 13 months after vaccination. Among the 29 cases with chickenpox vaccine immunization history, the majority had 10 to 49 lesions, accounting for 58.62% (17 cases). The trunk was the most common site of lesions, accounting for 44.83% (13 cases). About 51.72% (15 cases) reported "no or mild" pain intensity. The median ( Q1, Q3) scores for the worst pain, duration of pain and the time to crusting of lesions in the herpes zoster cases were 3 (1.5, 5) points, 10 (1.5, 12.5) days and 10 (6.5, 13) days, respectively. There was no statistically significant difference in the constituent ratio of the location of lesions, number of lesions and pain degree among the cases with vaccination history, without vaccination history and with unknown vaccination history ( P>0.05). There was also no statistically significant difference in the distribution of pain score, duration of lesions and duration of pain across the three groups ( P>0.05). Conclusion:Wild strains are the predominant pathogens in herpes zoster cases under 20 years old in Beijing City during 2017-2021. The varicella vaccination has no significant impact on the clinical manifestations of herpes zoster cases.
