Background Exposure to air pollutants increases the risk of diseases in multiple systems, including respiratory and cardiovascular systems, yet its association with neurological diseases remains unclear. Objective To quantitatively evaluate the association between short-term exposure to air pollutants and outpatient and emergency visits for neurological diseases, identify potential susceptible populations, and quantify associated disease burden. Methods Daily 24-hour average concentrations of fine particulate matter (PM_2.5), inhalable particulate matter (PM₁₀), sulfur dioxide (SO₂), nitrogen dioxide (NO₂), and carbon monoxide (CO), daily maximum 8-hour average concentration of ozone (O₃), daily meteorological data (24-hour average temperature, 24-hour average relative humidity), and data on daily outpatient and emergency department visits for neurological diseases from two hospitals in Conghua District, Guangzhou, China, were collected from 2015 to 2022. A time-stratified case-crossover design was adopted, and a conditional Poisson regression model was constructed to analyze the association between air pollution exposure and neurological disease visits. Two-pollutant models and sensitivity analysis were used to validate model stability. Stratified analyses by season (cold season: from November to March; warm season: from April to October), sex (male, female), and age (≤45 years, 46–60 years, ≥61 years) were performed to identify vulnerable group. Additionally, the number and proportion of neurological disease visits attributable to short-term air pollutant exposure were calculated. Results A total of 72 673 outpatient and emergency department visits for neurological diseases were included during the study period. Most of the patients were middle-aged and elderly individuals (69.89% were over 45 years old) and females (60.25%). The results of single-pollutant models showed that for each interquartile range (IQR) increase in exposure to PM_2.5, PM₁₀, SO₂, NO₂, CO, and O₃, the risk of outpatient and emergency department visits for neurological diseases increased by 7.54% (95%CI: 4.69%, 10.46%), 6.66% (95%CI: 3.92%, 9.46%), 16.72% (95%CI: 10.58%, 23.19%), 8.12% (95%CI: 4.82%, 11.53%), 5.60% (95%CI: 2.34%, 8.97%), and 6.11% (95%CI: 2.91%, 9.40%), respectively. The results of the two-pollutant model showed that the association between PM_2.5 and SO₂ exposure and outpatient and emergency department visits for neurological diseases were relatively stable. The stratified analyses showed that the effect of SO₂ was stronger in the cold season. It was estimated that 8.32% (95%CI: 5.55%, 10.96%) and 6.65% (95%CI: 4.27%, 8.96%) of the outpatient and emergency department visits were attributable to short-term exposure to SO₂ and PM_2.5, respectively. Conclusion Exposure to PM_2.5 and SO₂ is associated with increased risks of outpatient and emergency visits for neurological diseases. SO₂ shows stronger effects during the cold season, and exposure to air pollution contributes to up to 8.32% of neurological disease visits.

Objective To investigate stress distributions of the knee joint at 0 and 15th day after anterior cruciate ligament reconstruction(ACLR)under a compressive force through the axis of the femoral shaft onto the proximal femur.Methods A three-dimensional(3D)finite element model of the human knee joint incorporating viscoelastic material properties was developed.The one-dimensional(1D)Prony series viscoelastic constitutive model parameters for articular cartilage,menisci,ligaments,and anterior cruciate ligament(ACL)grafts were determined by fitting experimental creep curves.The viscoelastic parameters of ACL grafts at 15th day after ACLR surgery were extrapolated.Finite element simulations were then performed to analyze the von Mises stress distributions in knee ligaments,ACL grafts,articular cartilage,and menisci under 1.5 kN vertical downward compressive load applied to the femur,with loading durations of 1 second and 600 seconds.Results At 15th day after ACLR surgery,the initial relaxation modulus and equilibrium modulus of human ACL grafts remained elevated compared to native ACL tissues,resulting in a significantly higher stress concentration within the grafts relative to healthy ACL.Despite the compromised mechanical properties of the grafts after ACLR surgery,the vertical downward compressive force applied to the femur under both short-term(1s)and prolonged(600 s)loading durations,exhibited a minimal biomechanical impact on articular cartilage and meniscal structures.Conclusions Following ACLR,vertical compressive loads during weight-bearing rehabilitation exercises such as standing demonstrate minimal impact on articular cartilage and meniscus,while promoting fibrous regeneration of the graft.This renders such exercises a prudent early-stage rehabilitation strategy.Graft preparation requires balanced consideration of elastic and viscous properties,with grafts exhibiting higher relaxation modulus and viscosity coefficient than healthy ACL proving more effective in maintaining early postoperative knee stability.

Objective To quantitatively assess the association of short-term exposure to polycyclic aromatic hydrocarbons (PAHs) in ambient fine particulate matter (PM2.5) with residents mortality. Methods A time-stratified case-crossover study was conducted from 2020 to 2022 among 10606 non-accidental residents by using the Guangzhou Cause of Death Surveillance System in Conghua District, Guangzhou. Exposure levels of PAHs in PM_2.5 and meteorological data during the study period were obtained from the Center for Disease Control and Prevention in Conghua District and the China Meteorological Administration Land Data Assimilation System (CLDAS-V2.0), respectively. Conditional Poisson regression model was used to estimate the exposure-response association between PAHs and the mortality risk. Results Fluoranthene, chrysene, benzo[k]fluoranthene, benzo[a]pyrene, and indeno[1,2,3-cd]pyrene were significantly associated with an increased risk of mortality. For every one interquartile range increase in exposure levels, the non-accidental mortality risks increased by 8.33% (95% CI: 1.80%, 15.27%), 4.67% (95% CI: 1.86%, 7.57%), 6.07% (95% CI: 2.08%, 10.21%), 4.62% (95% CI: 1.85%, 7.47%), and 4.70% (95% CI: 0.53%, 9.03%), respectively. The estimated non accidental deaths attributable to exposure to fluoranthene, chrysene, benzo[k]fluorine, benzo[a]pyrene and indine[1,2,3-cd]pyrene were 5.91%, 6.08%, 6.51%, 6.46%, and 4.21%, respectively. Conclusions Short-term exposure to PAHs in PM_2.5, including fluoranthene, chrysene, benzo[k]fluoranthene, benzo[a]pyrene and indine[1,2,3-cd]pyrene, was significantly associated with an increased risk of mortality among residents.

Objective:Continuous glucose monitoring (CGM) technology is used to compare the advantages of insulin degludec (IDeg) as a basal insulin regimen compared with insulin glargine (IGlar) in the treatment of adult type 1 diabetes mellitus.Methods:30 adult patients with T1DM admitted to Heji Hospital Affiliated to Changzhi Medical College from September 2019 to December 2020 were screened. According to the random number table method, the patients were randomly divided into two groups (insulin degludec group and insulin glargine group) at a ratio of 1∶1, respectively treated with IDeg, IGlar and aspartate insulin for 12 weeks. The main outcome measures were the coefficient of variation of blood glucose (CV), mean amplitude of glycemic excursions (MAGE), time in range (TIR), time above range (TAR) and time below range (TBR). The secondary outcome measures were mean blood glucose (MBG), standard deviation of blood glucose (SD), fasting blood glucose (FPG), 2 h postprandial blood glucose (2 h BG), hemoglobin A1c (HbA 1c), means of daily differences (MOOD), and the frequency of hypoglycemic events. Results:At 12 weeks of treatment, the HbA 1c, FPG, 2 h BG, MBG, SD, CV and MAGE of insulin degludec group were lower than those of insulin glargine group, with statistically significant difference (all P<0.05). The TIR in the insulin degludec group was significantly higher than that in the insulin glargine group [73(63, 75)% vs 43(28, 63)%, P<0.001], and the TAR was lower than that in the glycerine group [25(17, 23)% vs 35(33, 64)%, P=0.003]. From the curve spectrum of blood glucose level of the two groups, the stability of blood glucose in the insulin degludec group was better than that in the insulin glargine group. After 12 weeks of treatment, 8 cases (8/15) in insulin degludec group had HbA 1c<7.0%, and 4 cases (4/15) in insulin glargine group had HbA 1c<7.0%, without statistically significant difference ( P=0.264). There were 7 cases (7/15) in the insulin degludec group and 1 case (1/15) in the insulin glargine group who achieved high quality blood glucose control, with statistically significant difference ( P=0.035). At the 12th week of outpatient follow-up, the incidence of nocturnal hypoglycemic events in insulin degludec group was significantly lower than that in insulin glargine group (4/15 vs 11/15, P=0.027). Conclusions:Compared with insulin glargine, insulin degludec can achieve higher blood glucose compliance rate, lower blood glucose level and reduce blood glucose fluctuations in patients with type 1 diabetes.

Background: At present, clinical dilemma remains to be solved in terms of therapy-choices for specific locally advanced cervical cancer (LACC) patients: 1) Although concurrent chemoradiotherapy (CCRT) is recommended as the first choice for them, many patients, influenced by the Chinese culture, prefer to choose radical surgery (RS) as their primary treatment. The difference between the 2 therapies in improving patient prognosis is still unknown. 2) Laparoscopy has been questioned since the noted Laparoscopic Approach to Cervical Cancer trial. Nevertheless, clinical research on laparoscopic surgery under the strict tumor-free principle is still underway globally, therefore whether laparoscopic surgery can be used for specific LACC is also an urgent issue to be explored. Methods A multi-center, randomized controlled study is designed to investigate the effect of different treatment strategies on the prognosis and quality of life (QoL) in patients with specific locally LACC. A total of 402 patients will be enrolled over a period of 3 years. Eligible patients will be randomized (3:1) to either RS group or CCRT group. Patients assigned to RS group will be randomized (1:2) to the abdominal RS group or laparoscopic RS group. All patients will then be followed-up for 5 years. The primary end point is the 2-year progression-free survival (PFS). The secondary end points include 5-year PFS, 2-year overall survival (OS), 5-year OS, adverse events caused by RS or CCRT and QoL.

OBJECTIVE: To explore the genetic characteristics of a child with Focal segmental glomerulosclerosis and neurodevelopmental syndrome (FSGSNEDS). METHODS: A child with FSGSNEDS who had visited Shengli Oilfield Central Hospital on September 15, 2019 was selected as the study subject. Clinical data of the child was collected, and trio-whole exome sequencing (trio-WES), Sanger sequencing, chromosomal karyotyping analysis, and copy number variation sequencing (CNV-seq) were used to analyze the child and his parents. RESULTS: The child, a 3-year-old boy, had manifested developmental delay, nephrotic syndrome, and epilepsy. Trio-WES and Sanger sequencing showed that he has carried a heterozygous c.1375C＞T (p.Q459*) variant of the TRIM8 gene, for which both his parents were of the wild type. Based on guidelines from the American College of Medical Genetics and Genomics (ACMG), the variant was predicted to be pathogenic. No abnormality was found in the chromosomal karyotyping and CNV-seq results of the child and his parents. CONCLUSION The child was diagnosed with FSGSNEDS, for which the c.1375C＞T variant of the TRIM8 gene may be accountable.
