Objective:To investigate the impact of residual cholesterol (RC) on the progression of arteriosclerosis in individuals receiving physical examination.Methods:A cross-sectional study. Participants aged 18 years and above who underwent arteriosclerosis testing at the Health Management Center of Zigong Fourth People′s Hospital from January to December 2023 were selected as the subjects of the study. A total of 9 016 subjects were included in this study, of whom 6 213 were considered to have arteriosclerosis. The physical examination conclusions, basic information (age, gender, body mass index, waist circumference, blood pressure, history of hypertension, history of smoking and drinking), and biochemical indicators (lipids, fasting blood glucose, liver and kidney function) were extracted in those individuals. Based on the examination results, the subjects were categorized into arteriosclerosis and normal groups. The RC levels of the participants were calculated using a formula and then the subjects were categorized into binary and quartile RC groups. Additionally, four regression models were used to analyze the impact of RC levels on the progression of arteriosclerosis while adjusting for various confounding factors.Results:The RC level was (0.63±0.44) mmol/L in the normal group and (0.76±0.61) mmol/L in the arteriosclerosis group. Based on level of RC, the normal group was divided into two subgroups: 652 individuals with elevated RC level and 2 241 with normal RC level. In the arteriosclerosis group, there were 2 069 individuals with elevated RC level and 4 144 with normal RC level. Grouped according to quartiles of RC level, the number of individuals with RC in the Q1-Q4 interval in the normal group was 838 (28.97%), 752 (25.99%), 760 (26.27%), and 543 (18.77%), respectively, showing a gradual decreasing trend. The number of individuals with RC in the Q1-Q4 interval in the arteriosclerosis group was 1 414 (22.76%), 1 438 (23.15%), 1 589 (25.58%), and 1 771 (28.51%), respectively, showing a gradual increasing trend. The difference between the groups was statistically significant ( P<0.05). After adjusting for various factors by four regression models, it was found that elevated RC levels increased the risk of arteriosclerosis progression, with a odds ratio ( OR) of 1.381, 1.242, 1.233, and 1.214, respectively. Additionally, individuals in the Q4 RC level quartile had 1.502, 1.318, 1.311, and 1.284-times higher risk of arteriosclerosis progression when compared to those in the Q1 quartile. Conclusion:The impact of RC on the progression of arteriosclerosis tend to stabilize and remain consistent, indicating that elevated RC is an independent risk factor for the progression of arteriosclerosis.

Objective: To understand the coincidence rate of adjustable and non adjustable desks and chairs in primary and secondary schools in Shanghai, so as to provide a reference for the effective management of desks and chairs in schools. Methods: Stratified random cluster sampling was applied to measure 1 091 sets of desks and chairs in 33 classrooms of 7 primary and secondary schools in 4 districts of Shanghai including Huangpu, Hongkou, Yangpu and Jiading districts. The height examination data of seated students in the same semester were also collected to evaluate the matching type of functional size of desks and chairs and students height according to Functional Sizes and Technical Requirements of Chairs and Tables for Educational Institutions. Results: The matching coincidence rate of desk and chair distribution in primary and secondary schools was 22.5%, and the matching coincidence rates of primary, middle and high schools were 11.7%, 27.1% and 40.9% respectively ( χ 2=83.23, P <0.01); the matching coincidence rate of adjustable desks and chairs (28.2%) was significantly higher than that of fixed (18.2%) ( χ 2=14.49, P <0.01). The type of distribution of desks and chairs that do not correspond to national standards, from elementary school to high school, showing a trend of high desks with high chairs, low desks with high chairs to high desks with low chairs. Conclusion The coincidence rate of desk and chair distribution in primary and secondary schools is low, and the adjustable desks and chairs has improved the problems to a certain extent, but has not significantly improved the coincidence rate. It is necessary to further explore the effective management mode in the use of adjustable desks and chairs and improve the current situation of the use of desks and chairs in schools.

Neonatal onset multisystem inflammatory disease(NOMID), also known as chronic infantile neurological cutaneous and articular syndrome(CINCA), originates from perinatal period and mainly manifests urticaria, joint lesions, and central nervous system lesions.It is an autoinflammatory disease associated with mutations of NLRP3 located on chromosome 1q44.The early atypical clinical symptoms are prone to misdiagnosis.NOMID/CINCA should be differentiated from infectious diseases, familial cold autoinflammatory syndrome, Muckle-Wells syndrome, systemic juvenile idiopathic arthritis, mevalonate-kinase deficiency, tumor necrosis factor receptor-associated periodic syndrome, and other diseases.NOMID/CINCA is mainly diagnosed based on clinical symptoms, while genetic testing provides an essential supplementary for patients with atypical clinical manifestations.IL-1 targeted therapies including anakinra, rilonacept, and canakinumab, have been proven with sustained efficacy in treating NOMID/CINCA.This article reviews the progress on diagnosis and treatment of NOMID/CINCA.

Neonatal hyperammonemia has great damage to the central nervous system, which can lead to severe disability and even death.Early reduction of blood ammonia and shortening the duration of hyperammonemia coma can improve the poor prognosis of the central nervous system.Renal replacement therapy can reduce blood ammonia quickly and effectively which is an important treatment for neonatal hyperammonemia.Common kidney replacement therapies include peritoneal dialysis, intermittent hemodialysis, continuous renal replacement therapy and hybrid therapy.This review aims to elaborate the indications of renal replacement therapy, the advantages and disadvantages of various renal replacement therapy modes in the treatment of neonatal hyperammonemia and hybrid therapy.

Objective:To investigate the lymphocyte subsets and clinical characteristics of children with abnormal reaction to Bacillus Calmette-Guérin(BCG)vaccination.Methods:A total of 35 children with BCG disease diagnosed in the Children′s Hospital Affiliated to Xi′an Jiaotong University from January 2013 to December 2019 were enrolled retrospectively.Patients with strong local reaction and lymphadenitis after vaccine injection were selected as the localized group, and with lymphadenitis complicated with distant organ involvement were classified as the disseminated group.The differences in clinical infection indicators, demographic data, lymphocyte subsets and prognosis between the two groups were compared.Results:There are 25 cases in the localized group and 10 cases in the disseminated group, male 20 cases and female 15 cases.Compared with the localized group, the incidence of cough, fever and growth retardation all increased in the disseminated group, with statistical significance(all P<0.05). Lymphocyte ratio[(61.14±18.61)% vs.(39.64±31.45)%], T lymphocytes [CD3 + (×10 6/L): (1 821±487)vs.(1 065±539)], helper/inducible T lymphocytes[CD3 + CD4 + (×10 6/L): (1 058±357)vs.(445±140)], double positive T lymphocytes[CD3 + CD4 + CD8 + (×10 6/L): (24.07±7.17)vs.(14.10±8.89)], CD4 + /CD8 + ratio[CD4 + /CD8 + (%): (1.65±0.73)vs.(1.00±0.25)], natural killer cells[CD16 + CD56 + (×10 6/L): (19.70±2.34)vs.(12.76±7.01)]were lower in the disseminated group than those in the localized group and the differences were significant(all P<0.05). In the disseminated group, 6 cases were diagnosed with immunodeficiency disease and 7 cases died during the follow-up period.All the children in the localized group were cured. Conclusion:Most BCG reaction have a good prognosis, while disseminated children combined with primary immune deficiency have worst prognosis.Early lymphocyte subsets analysis is effective for BCG disease screening.

Toll-like receptor 3 (TLR3) is a member of the TLR family, mediating the transcriptional induction of type I interferons (IFNs), proinflammatory cytokines, and chemokines, thereby collectively establishing an antiviral host response. Studies have shown that unlike other TLR family members, TLR3 is the only RNA sensor that is utterly dependent on the Toll-interleukin-1 receptor (TIR)‍-domain-containing adaptor-inducing IFN-‍β (TRIF). However, the details of how the TLR3-TRIF signaling pathway works in an antiviral response and how it is regulated are unclear. In this review, we focus on recent advances in understanding the antiviral mechanism of the TRIF pathway and describe the essential characteristics of TLR3 and its antiviral effects. Advancing our understanding of TLR3 may contribute to disease diagnosis and could foster the development of novel treatments for viral diseases.

Background: A small shift in high-sensitivity cardiac troponin T (hs-cTnT) assays can lead to different result interpretation and consequent patient management. We explored whether a small bias could be detected using conventional internal quality control (QC) procedures, evaluated the performance of moving average (MA)-based QC procedures, and proposed a new QC procedure based on the moving rate (MR) of positive patient results of hs-cTnT assays. Methods: The ability of conventional QC to detect a 5 ng/L bias was examined using the 1 3s/ 22s/R4s multi-rule procedure as deviation rules.We developed MA and MR procedures for the hs-cTnT assay using eight months of patient data. The performance of different MA or MR procedures was investigated by calculating the median number of patient samples affected until a bias introduced into the dataset was detected (MNPed). After comparing the MNPed across different procedures, we selected an optimal MA or MR procedure for validation. Validation graphs were plotted using the minimum, median, and maximum number of results affected until bias detection. Results: Our conventional QC procedures could not detect a positive bias of 5 ng/L. When a positive bias was introduced, MNPed was much higher using MA than using MR, with cut-off values of 5 ng/L and 14 ng/L, respectively. MR validation charts for optimal procedures provided insight into the MR performance. Conclusions The MR procedure could detect different errors with few false alarms. In the hs-cTnT assay, the MR procedure with a smaller cut-off value outperformed MA and conventional QC procedures for small bias detection.

Objective:To investigate the clinical characteristics of neonatal congenital tongue base cyst.Methods:This retrospective study involved 35 neonates with congenital tongue base cyst diagnosed in the neonatal intensive care unit (NICU) of Xi'an Children's Hospital from June 2013 to December 2019. General information, clinical manifestations, supplementary results, treatment and prognosis of these babies were described.Results:(1) The median age at the onset of the disease was 12.5 (0~28) d and the median age at admission was 15 (0~28) d for these babies. The main clinical manifestations were laryngeal stridor (28/35, 80.0%), inspiratory dyspnea and crying, especially when feeding (26/35, 74.3%) and choking and spitting with feeding (23/35, 65.7%). (2) Among the 35 cases, 15 (42.9%) required emergency endotracheal intubation due to significant dyspnea when were admitted to the NICU and five out of them were considered for having tongue base mass under laryngoscopy, while the other 10 cases underwent bedside electronic laryngoscopy after endotracheal intubation, in which space-occupying lesions were found. Tongue base cyst was considered in seven cases with laryngeal stridor complicated by protracted pneumonia using fiberoptic bronchoscopy. The other 13 cases were examined by electronic laryngoscope and considered as tongue base cyst. Thirty-five cases underwent cervical ultrasound and only five of them were considered as tongue base tumor. Thirty-two cases underwent cervical CT scan and only two of them were normal. Three cases were found to have tongue base cyst by cranial MRI. (3) Thirty-four cases were treated by radiofrequency ablation assisted with self-retaining microlaryngoscope and general anesthesia, while the other one firstly received puncture and drainage under direct laryngoscope due to the difficult intubation because of the huge tongue base cyst and then underwent surgery when stable. Only one case (2.9%) relapsed after surgical treatment during regular follow-up.Conclusions:Neonatal congenital tongue base cyst has an early onset and atypical clinical manifestations. Electronic laryngoscopy/fiberoptic bronchoscopy combined with neck CT or MRI examination should be performed promptly in patients with laryngeal stridor and inspiratory dyspnea to facilitate the accurate diagnosis and timely surgery is required for.

Bluetongue virus (BTV) causes Bluetongue (BT) of ruminants vectored by culicoides midges. It is also a classic model for studying the release mechanism of non-enveloped virus. This review begins with the infection and assembly of BTV, then summarizes the advances of different ways of releasing BTV. This includes BTV-induced autophagy and the release as extracellular vesicles via multivesicular bodies, BTV-induced apoptosis and the lytic release, as well as different pathways of release through budding via plasma membrane. The regulatory mechanisms of NS3 which is a key non-structural protein during the release of BTV are also discussed, providing a basis for further understanding the molecular mechanisms underpinning the infection, proliferation and release of BTV.
