Objective: To investigate the association of special family structure and physical activity with psychological sub health among secondary vocational school students, so as to provide reference to inform mental health promotion in the population. Methods: From September to December 2024, a convenience sample was drawn from 16 schools including 5 141 secondary vocational school students across 8 provinces (municipalities) in China (Fujian, Chongqing, Guangdong, Guangxi, Hubei, Jiangxi, Shanghai, Zhejiang). A self developed questionnaire, Multidimensional Sub health Questionnaire of Adolescents and International Physical Activity Questionnaire Short Form were used to investigate and evaluate basic information, family structure, psychological sub health status and physical activity. Descriptive statistics and Logistic regression analysis were performed to explore relationships of special family structures and physical activity with psychological sub health in secondary vocational school students. Results: The detection rate of psychological sub health among secondary vocational school students was 11.0%. The reporting rates for secondary vocational school students who lost their father or lost their mother, whose parents divorced, whose parents remarried, and those from special family structures were 2.8%, 0.8%, 11.8%, 3.9%, and 14.7%, respectively. Moreover, the detection rates of psychological sub health and its sub dimensions significantly differed among secondary vocational school students grouped by family type (divorced parental families, remarried parental families and special family structures)( χ 2=5.90-22.67, all P <0.05). Binary Logistic regression indicated that maternal bereavement was associated with a higher risk of conduct problems [ AOR ( 95% CI )= 2.90(1.15-7.33)], and parental divorce was associated with a higher risk of psychological sub health ( AOR= 2.71 , 95%CI =1.04- 7.06 ) among secondary vocational school students (both P <0.05). Interaction analysis showed that both students with a special family structure and insufficient physical activity [ AOR (95% CI )=1.99(1.44-2.75)] and those with a non-special family structure and insufficient physical activity [ AOR (95% CI )=1.81(1.48-2.22)] were associated with increased risks of psychological sub health among secondary vocational school students (both P <0.01). Conclusion Special family structure and physical activity are associated with psychological sub health among secondary vocational school students; early identification and assessment based interventions for those with a special family structure should be strengthened, while school based physical activity should be implemented to increase physical activity levels,thereby reducing the risk of psychological sub health.

For women with type 1 diabetes mellitus (T1DM) reaching reproductive age, the disease course generally protracted, often accompanied by varying degrees of microvascular complications. Hence, the need for preconception planning and comprehensive screening and management of complications is urgent to avoid serious maternal and fetal complications. The recommended preconception glycated hemoglobin control target is currently set at<6.5%. In cases of unintended pregnancies where pre-existing microvascular complications are present, multidisciplinary standardized management during the pregnancy is essential. Although a multidisciplinary expert consensus on gestational management of T1DM has been published in China in 2020, several issues remain regarding the clinical management of T1DM in pregnancy across the nation. Strengthening nutritionally balanced management, actively and reasonably utilizing insulin therapy, and leveraging new technologies such as the internet plus artificial intelligence hold promise to achieve more optimal glucose control, reduce the incidence of maternal and fetal complications associated with T1DM, and ultimately achieve favorable outcomes for both mother and child.

American Aiabetes Association (ADA) updated the "Management of Diabetes in Pregnancy: Standards of Care in Diabetes-2025" based on the latest medical evidence. The main points of this updated guideline include the preconception counseling section, the continuous glucose monitoring part in the glycemic goals in pregnancy section, the nutritional counseling part and automated insulin delivery systems part in the management of diabetes in pregnancy section, and the use of lipid-lowering drugs medications and statins therapy part in the pregnancy and drug considerations section. This article provides a detailed introduction and interpretation of the updated guidelines, in order to provide a reference for clinical practice.

This article reported a case of a newborn with congenital absence of the penis. The prenatal examinations were unremarkable. Physical examination of the newborn revealed abnormal external genitalia, with well-developed scrotum and fully descended testicle in normal size, but without the penis. Postnatal ultrasound showed no obvious signals of uterus and ovaries in pelvis and had normal bilateral testicles and urinary system. The diagnosis was congenital absence of the penis.

Chronic disease patients often experience negative emotions such as anxiety and depression,and the accurate assessment of these emotions is crucial for developing effective care plans and interventions.Traditional assessments of negative emotions are limited by subjectivity,error and accessibility issues,making precise identification and evaluation difficult.In recent years,vision technology has demonstrated unique advantages in emotion recognition due to its accuracy,speed,consistency,objectivity nature.This paper reviews the development process of computer vision technology,the content and effects of its application in negative emotion assessment for chronic disease patients,and the current challenges,in order to provide references for the evaluation of chronic disease patients'negative emotions.

Objective:To screen and analyze the carcinogenesis-related differential expression profile of long non-coding RNAs(LncRNAs)in oral lichen planus(OLP)mucosa tissue,and preliminarily analyze their functions,to explore their possible role in the development of OLP.Methods:High-throughput sequencing technology was used to construct differential expression profile from 5 cases of erosive OLP lesions and 5 of normal oral mucosa.LncRNAs that are closely related to the carcinogenesis of OLP were ob-tained by bioinformatics analysis.Results:400 LncRNAs associated with OLP were screened,of which 250 were up-regulated and 150 were down-regulated,and 5 LncRNAs were obtained with differential expression associated with OLP carcinogenesis:LncRNA 54055,100128560,399717,378825 and 100130231.Conclusion:400 LncRNAs are differentially expressed in the mucosa of erosive OLP lesions,and 5 of them are related to the incidence and carcinogenesis tendency of OLP.

Objective:To analyze the current preparation and usage situation of first-aid drugs in the rescue vehicles in children's medical institutions, and provide references for optimizing the list of emergency drugs.Methods:First-aid drug lists in the rescue vehicles of 12 children's medical institutions from 11 provinces and municipalities in China were collected through questionnaire surveys, and the drugs as well as their quantities were compared. The existing problems in the use of first-aid drugs in the 12 medical institutions were investigated by on-site interviews. The usage information of first-aid drugs in the rescue vehicles of the General Surgery and Cardiology Department of Shanxi Children's Hospital from May 2022 to April 2023 was collected through the hospital information center, and usage frequency and dosage per patient of the drugs were calculated. Descriptive statistical analysis was conducted on the collected data.Results:The first-aid drug lists in 12 hospitals were various, including 7 to 22 kinds of drugs and involving a total of 23 drugs. These mainly included vasoactive drugs, cardiotonic drugs, antiarrhythmic drugs, antiangina and anti-ischemic drugs for the heart, antispasmodic drugs, diuretics, dehydrating drugs, sedative-hypnotic drugs, and glucocorticoids, all of which were injections. The drugs that were included in all the lists of 12 hospitals were epinephrine, dopamine, dexamethasone, furosemide, and atropine. The drug lists of different rescue vehicles throughout the hospital were the same in 4 hospitals, while the lists varied among departments based on their specific clinical needs in the other 8 hospitals. None of the 12 hospitals had a first-aid drug usage manual. The on-site interview results showed that, the existing problems about drug preparation and use in rescue vehicles mainly involved the following 6 aspects: drug types, quantities, labels, storage, procurement, and usage. In Shanxi Children's Hospital, the types and quantities of first-aid drugs in rescue vehicles of General Surgery Department and Cardiology Department were the same. There were 6 and 9 kinds of drugs were used in the 2 departments during rescue operations, respectively. The drugs that were never used in either department included promethazine, lidocaine, diazepam, phenobarbital, raceanisodamine, sodium bicarbonate, atropine, glucose, and calcium gluconate.Conclusions:The phenomenon of unreasonable kinds and quantities of first-aid drugs in the rescue vehicles existed in the children's medical institutions, and the drugs provided did not fully match the actual clinical needs. There was an urgent need for preparation guidelines and usage manuals of first-aid drugs that were suitable for children's medical institutions to enhance the scientificity of drug supply and the correctness of usage.

Objective To investigate the application value of pan-immune-inflammation value(PIV),hypersensitive C-reactive protein(hs-CRP)/albumin(ALB)ratio(HCAR)and procalcitonin/platelet count ratio(PCT/PLT)in pulmonary infection in elderly patients with chronic obstructive pulmonary disease(COPD).Methods A total of 143 elderly patients with COPD and pulmonary bacterial infection were selected as the infected group.Meanwhile,143 elderly patients with COPD and without pulmonary infection were selected as the uninfected group.Patients in the infected group were furthrer divided into the mild group(47 cases),the moderate group(51 cases)and the severe group(45 cases)according to the degree of pulmonary infection.They were divided into the favorable prognosis group(112 cases)and the poor prognosis group(31 cases)according to the prognosis.Blood biochemical indicators,PIV,HCAR and PCT/PLT were compared between groups.The relationship between above indicators and pulmonary infection,infection degree and the prognosis was analyzed.Results Compared with the uninfected group,neutrophil(NEU),monocyte(MON),hs-CRP and PCT levels were higher,while lymphocyte(LYM)and ALB levels were lower in the infected group(P＜0.05).PIV,HCAR and PCT/PLT were higher in the infected group and the poor prognosis group than those in the uninfected group and the favorable prognosis group,respectively(P＜0.05).PIV,HCAR and PCT/PLT in the mild group,the moderate group and the severe group increased in sequence(P＜0.05).Spearman correlation analysis showed that PIV,HCAR and PCT/PLT were positively correlated with the degree of pulmonary infection(P＜0.05).Multivariate Logistic regression analysis showed that high levels of PIV,HCAR and PCT/PLT were independent risk factors for pulmonary infection in elderly patients with COPD(P＜0.05),and also independent risk factors for poor prognosis in patients with pulmonary infection(P＜0.05).The areas under the curve(AUC)of PIV combined with HCAR and PCT/PLT for diagnosing pulmonary infection in elderly patients with COPD and predicting poor prognosis in patients with pulmonary infection were 0.980 and 0.910(P＜0.05).Conclusion PIV,HCAR and PCT/PLT are related to COPD with pulmonary infection in the elderly.They can help to identify pulmonary infection,judge the condition of pulmonary infection and evaluate the prognosis in patients with pulmonary infection.
