Objective:To investigate factors influencing frequent episodes (≥ 4 episodes within 1 year) in children with moderate-to-severe atopic dermatitis (AD) in China.Methods:A national multicenter cross-sectional study was conducted. Patients under the age of 18 years diagnosed with moderate-to-severe AD were enrolled at dermatology clinics in 18 medical institutions across 12 provinces and municipalities in China between June 12 and August 8, 2023. At the time of the visit, their guardians completed a structured questionnaire covering demographic characteristics, clinical features of AD, personal and family history, factors associated with frequent episodes of moderate-to-severe AD, compliance with treatment, and disease awareness. Statistical analyses included t tests, one-way analysis of variance, rank-sum tests, and chi-square tests, with multiple-response analysis applied for multiple-choice questions. Results:A total of 965 valid questionnaires were collected, and 965 children with moderate-to-severe AD were included. Among them, there were 531 males and 434 females, 678 (70.3%) were aged 2 - < 12 years, 837 (86.7%) were from urban areas, the age at onset was 2.47 ± 3.03 years, and the median frequency of AD episodes in the past year was 4 times. These children were divided into 2 groups based on the median episode frequency: < 4-episode group (439 cases, 45.5%) and ≥ 4-episode group (526 cases, 54.5%). Compared with the < 4-episode group, children in the ≥ 4-episode group showed younger ages at onset (2.22 ± 2.98 years vs. 2.76 ± 3.06 years, P = 0.006) and higher proportions of patients with comorbid allergic diseases in both the children themselves (82.9% [436/526] vs. 69.7% [306/439], χ2 = 23.42, P < 0.001) and their relatives (66.0% [347/526] vs. 57.4% [252/439], χ2 = 7.46, P = 0.006). Children in the ≥ 4- episode group also had higher monthly usage of moisturizers (150 [30, 300] g vs. 60 [6, 200] g) and daily frequency of moisturizer use, greater disease awareness, but more severe fear of medication use (all P < 0.05). The region and the human development index level were both significantly associated with the episode frequency (both P < 0.001), with the highest proportion of children from South China in the ≥ 4- episode group (36.3%, 191/526). Children in the ≥ 4-episode group also had a longer duration of topical glucocorticoid use than those in the < 4-episode group ( Z = -2.21, P = 0.027). External triggers associated with AD episodes mainly included heat exposure (50.36%, 486/965), hot water bathing (40.73%, 393/965), seafood (23.52%, 227/965), and dust mites (33.37%, 322/965) . Conclusion:In children with moderate-to-severe AD in China, factors influencing frequent episodes may include residence in southern or economically developed regions, earlier age at onset, having a personal or family history of allergic diseases, and fear of medication use.

Objective:To assess the effects of recognition function of four-lead electrocardiogram(ECG)synchronization technique and multi-parameter fusion technique in reducing the number of false alarms and improving the quality of alarms in intensive care units(ICU).Methods:Four-lead ECG synchronization technique and multi-parameter fusion technique were used to strengthen the monitoring and assessment for the alarm of clinical monitors,and reduce the false alarm rate of monitors.The clinical alarm data of bed units corresponding to 48 monitors in clinical use of ICU,cardiovascular intensive care unit(CCU)and neurosurgery intensive care unit(NICU)of Hainan General Hospital from October 14 to December 27,2024 were selected.According to the opening and close of the four-lead ECG synchronization and multi-parameter fusion technique algorithm of the monitors,they were divided into group A(opened four-lead ECG synchronization and multi-parameter fusion),group B(opened four-lead ECG synchronization,but closed multi-parameter fusion),group C(closed four-lead ECG synchronization,but opened multi-parameter fusion)and group D(closed four-lead ECG synchronization and multi-parameter fusion),with 12 units in each group.The numbers of total alarms and false alarms generated by monitor of each bed unit among different optimization strategies were compared.Results:The numbers of average daily alarm of the monitors in groups A,B and C were respectively(134.2±32.4)cases,(392.5±68.2)cases and(583.4±126.5)cases,which were lower than those in group D(1 073.2±168.6),with statistically significant differences(Z=3.45,2.94,2.52,P<0.05).The optimization rates of the alarm numbers in groups A,B and C were increased by 87.51%,63.47%and 45.67%,respectively.The rates of average false alarm of the monitors in groups A,B and C were respectively(1.04±0.15)%,(1.73±0.12)%and(2.07±0.08)%,which were lower than(3.76±0.2)%in group D,with statistically significant differences(Z=3.45,2.94,2.52,P<0.05).Conclusion:Four-lead ECG synchronization technique and multi-parameter fusion technique can effectively optimize the number of alarms in ICU,and reduce the proportion of false alarms of monitors in department,and decrease fatigue of medical staffs for alarm.

Diabetic cardiomyopathy(DCM)is one of the complications of diabetes.The onset of DCM is hidden and easy to be ignored.Myocardial injury is serious in the later stage and the prognosis is poor.At present,symptomatic treatment is the main clinical treatment.Cuproptosis is a novel cell death mode caused by imbalanced copper ion concentration in the body,leading to mitochondrial metabolic abnormalities,which is one of the important mechanisms of DCM.Targeted cuproptosis pathway therapy for DCM is currently a focus and hotspot of research.The"Qi Luo Theory"is one of the disciplinary branches of the theory of collateral diseases,which mainly operates the meridian Qi system.The syndrome and treatment system of collateral diseases cardiovascular diseases have important guiding significance for the treatment of DCM.Traditional Chinese medicine believes that deficiency and stagnation of Qi that in the collaterals are the root causes of DCM,with stasis and toxin obstructing collaterals and damage to the heart collaterals being the core of the disease.The ultimate outcome is the deficiency and decline of Qi,Blood,Yin,and Yang in the heart.The"Qi Luo Theory"and cuproptosis have similarities in physiological functions and pathological processes,and cuproptosis can be said to be one of the microscopic manifestations of the"Qi Luo theory".Based on this,the staged treatment principle of tonifying deficiency and promoting stagnation as the norm,attacking and supplementing simultaneously as the principle,and strengthening the body and consolidating the core has been proposed,in order to provide theoretical reference for the clinical treatment of DCM.

BACKGROUND:Skeletal muscle insulin resistance is the key pathological link of type 2 diabetes.The traditional Chinese medicine compound Roujishuncuiyin can effectively improve skeletal muscle insulin resistance,but its mechanism has not been clarified.OBJECTIVE:To explore the mechanism of Roujishuncuiyin on skeletal muscle insulin resistance in type 2 diabetes mice.METHODS:Forty db/db mice with type 2 diabetes mellitus were randomized into a model group,a low-dose Roujishuncuiyin group,a high-dose Roujishuncuiyin group,and a positive drug group,with 10 mice in each group.The latter three administration groups were given 157.5 mg/g and 630 mg/g Roujishuncuiyin and 200 mg/g metformin hydrochloride aqueous solution by gavage once a day,respectively.In addition,10 db/dm mice were selected as the blank control group.Mice in the model and blank control groups were given the same dose of 0.9％NaCl solution by gavage.After 12 weeks of intervention,fasting blood glucose was measured in each group of mice,and oral glucose tolerance test was performed to calculate the area under the blood glucose curve.ELISA was used to detect serum insulin level and calculate the resistance index.Mitochondrial structure of skeletal muscle tissue was observed under transmission electron microscopy.Western blot was used to detect the expression levels and phosphorylation levels of protein kinase B(AKT)and glycogen synthase kinase 3β(GSK-3β)proteins in skeletal muscle.RESULTS AND CONCLUSION:(1)Compared with the blank control group,fasting blood glucose,fasting insulin and insulin resistance index were significantly higher in the model group(P＜0.05),the area under the curve of the oral glucose tolerance test was significantly increased(P＜0.05),the expression of p-AKT and p-GSK3β proteins in tibialis anterior muscle was significantly decreased(P＜0.05),and there was a large amount of mitochondrial damage in tibialis anterior muscle and a large number of lipid droplets in the interstitium.(2)Compared with the model group,fasting blood glucose,fasting insulin,and insulin resistance index were significantly reduced in the low-and high-dose Roujishuncuiyin groups and the positive control group(P＜0.05),the area under the curve of the oral glucose tolerance test was reduced(P＜0.05),the expression of p-AKT and p-GSK3β proteins in the tibialis anterior muscle was significantly elevated(P＜0.05),and mitochondrial damage in the tibialis anterior muscle was significantly ameliorated,with decreased lipid droplets in the interstitium.(3)The above indexes were better in the high-dose Roujishuncuiyin group than the low-dose Roujishuncuiyin group(P＜0.05),while there was no significant difference between the high-dose Roujishuncuiyin group and positive control group(P＞0.05).To conclude,by upregulating the protein levels of p-AKT and p-GSK3β in skeletal muscle tissue,the traditional Chinese medicine compound Roujishuncuiyin can improve structural disorders and mitochondrial morphology in skeletal muscle tissue,reduce insulin resistance in the skeletal muscle and regulate glucose homeostasis in the body.

To report 2 cases of Iso-Kikuchi syndrome, both of which were congenital. Case 1, a 7-month-old female infant, visited the hospital due to abnormalities in the nail plate of the left index finger for 7 months; case 2, a 3-year-old male child, also visited the hospital due to abnormalities in the nail plate of the left index finger for 3 years. The 2 patients both presented with 2 tiny, independent nail plates on both sides of the nail bed of the left index finger, instead of normal nail plates. Based on their clinical features, the 2 patients were diagnosed with Iso-Kikuchi syndrome (congenital onychodysplasia of the index finger). The mother of case 1 had a history of progesterone use to prevent miscarriage during pregnancy, the mothers of the two patients both suffered from hypothyroidism and continued to receive thyroid hormone replacement therapy during pregnancy, and the mother of case 2 had a history of gestational diabetes. It is still unclear whether these comorbidities and drugs are directly related to the occurrence of Iso-Kikuchi syndrome.
