Local anesthetics (LAs), such as articaine (AT), exhibit limited efficacy in inflammatory environments, which constitutes a significant limitation in their clinical application within oral medicine. In our prior research, we developed AT-17, which demonstrated effective properties in chronic inflammatory conditions and appears to function as a novel oral LA that could address this challenge. In the present study, we further elucidated the beneficial effects of AT-17 in acute inflammation, particularly in oral acute inflammation, where mitochondrial-related apoptosis played a crucial role. Our findings indicated that AT-17 effectively inhibited lipopolysaccharide (LPS)-induced nerve cell apoptosis by ameliorating mitochondrial dysfunction in vitro. This process involved the inhibition of mitochondrial reactive oxygen species (mtROS) production and the subsequent activation of the NRF2 pathway. Most notably, improvements in mitochondria-related apoptosis were key contributors to AT-17's inhibition of voltage-gated sodium channels. Additionally, AT-17 was shown to reduce mtROS production in nerve cells through the Na⁺/NCLX/ETC signaling axis. In conclusion, we have developed a novel local anesthetic that exhibits pronounced anesthetic functionality under inflammatory conditions by enhancing mitochondria-related apoptosis. This advancement holds considerable promise for future drug development and deepening our understanding of the underlying mechanisms of action.

Obesity, as a chronic recurrent disease, has become a major public health challenge in China. To implement the requirements of the Healthy China Initiative (2019—2030), under domestic guidelines or consensus statements on overweight and obesity, and in alignment with the latest scientific advances globally, the Quality control protocol for adult overweight and obesity screening in health management (examination) institutions (2025 edition) was developed. This protocol was drafted by the Health Management Center of Shanghai Changzheng Hospital and formulated through multiple rounds of deliberation by experts in China’s health examination quality control field. The protocol establishes unified standards for screening facilities, personnel qualifications, and measurement or testing procedures. It defines specific screening items, outlines a standardized screening pathway, and sets requirements for the final medical review, ensuring the scientific validity, effectiveness, and safety of the screening process. The implementation of this protocol will enhance the consistency of weight management practices for adults across health examination institutions and strengthen the quality control of overweight and obesity screening programs.

Objective:To analyze the clinical symptoms and epidemiological characteristics of patients with tsutsugamushi disease (TD) in Utica County, Shiyan City, providing reference for scientific prevention and control of TD.Methods:The information of 57 TD patients admitted to the Department of Infectious Diseases of the People's Hospital of Utica County in Shiyan City from January to December 2022 was collected, including age, gender, occupation, clinical manifestations (tarsus or chigger, high fever, rash and accompanying syndromes), laboratory and imaging test results, and field work and travel history. Blood samples and body crusts were collected, and enzyme-linked immunosorbent assay (ELISA) and polymerase chain reaction (PCR) were used to detect antibodies against Orientia tsugamushi (Ot-Ab-IgM) and Orientia tsutsugamushi (Ot). The scores of each patient were calculated using the TD Diagnostic Scale. A score of ≥8.5 was considered a clinical diagnosis of TD. According to the number of system functional damages (0, 1, 2, ≥3), 57 patients were divided into 4 groups, A, B, C, and D, TD was analyzed for system functional damages of each system.Results:Among the 57 TD patients, 26 (45.61%) were male and 31 (54.39%) were female, and the proportion of patients aged 40 - 79 years was 92.98% (53/57); farmers accounted for 89.47% (51/57). May was the peak of TD incidence, with 19 cases, which accounted for 33.33% (19/57) of the total number of patients affected that year. Fifty-four patients had a history of fieldwork or field trips before the onset of the disease. The incidence of high fever in 57 TD patients was 100.00%(57/57), the detection rate of body scorch or chiggers was 80.70% (46/57), and the incidence rate of rash was 98.25% (56/57); the incidence rate of tsutsugamushi disease triad (accompanied by scabs, high fever, and rash) was 80.70% (46/57); the incidence of eosinophil decline was 100.00%(57/57), and 77.19% (44/57) of TD patients experienced multiple-system functional damage (MSFD). The TD score diagnostic scale for 57 patients ranged from 8.5 to 10.5 points. After being hospitalized for 1 - 5 days, all TD patients experienced a decrease in body temperature to the normal range, and the damage to various systems functional gradually recovered.Conclusions:TD has become one of the most common natural infectious diseases in Utopia County, Shiyan City, Hubei Province. The patients are mainly middle-aged and elderly people, and the triple syndrome is a typical clinical manifestation. Asymptomatic injuries to the blood system, liver and kidneys are the most common.

Objective: To observe and analyze rightzopiclone on the improvement of sleep disorders in patients with Alzheimer disease. Methods: Eighty-four Alzheimer disease patients with sleep disorders admitted to the Department of Neurology of the Dalian University Affiliated Xinhua Hospital from August 2016 to August 2018 were selected and randomly divided into observation group and control group, with 42 patients in each group. The patients in the observation group were given rightzopiclone orally, while the patients in the control group were given alprazolam orally. The Pittsburgh Sleep Quality Index (PSQI) was applied to assess the sleep state of the two groups before and after the treatment. Results: The total effective rates of sleep improvement in the observation group were 78.57% and 92.86% after 2 and 4 weeks of the treatment, which was significantly higher than that in the control group of 54.76% and 73.81% (P<0.05), and the PSQI assessment results were also significantly better than those in the control group (P<0.05). Conclusions Rightzopiclone is helpful for the improvement of sleep state of Alzheimer disease patients with sleep disorders, and it has high clinical application value.

Objective    To explore the practical feasibility of the weaving technique for pectus carinatum. Methods    From January 2011 to December 2018, a total of 51 patients with pectus carinatum, including 47 males and 4 females at age of 9-29 (13.7±2.9) years, were applied with minimally invasive waving technique for the correction. The steel plate was inserted through the subcutaneous layer, intercostal space and over the sternal surface under direct thoracoscopic vision. The number of implanted steel plates was determined by the degree of chest wall deformity. The steel plate was removed 2 years after surgery. Results    All the operations were successfully completed, the average operation time was 63.9±15.8 min, the amount of bleeding was 19.8±8.8 mL, and the duration of postoperative hospitalization was 4.6±1.6 d. The adverse events included intercostal artery injury (n=2), pneumothorax (n=4), pleural effusion (n=3) and skin rupture (n=1). And there were 29 patients of moderate pain (numerical rating scale 4-6 points) on the first day after surgery, but no patient was asked to remove the steel palate due to intolerable discomfort. All patients were followed up after plate placement. Of the 51 patients, the plates were removed in 37 patients until 2 years after placement, and the duration of postoperative hospitalization was 1.4±0.5 d. After 33 (1-48) months of routine follow-up after the removal of the plate, 22 patients achieved excellent outcomes and 9 patients with good outcomes. Besides, there were 5 patients with fair outcome and 1 patient with poor outcome. No adverse effect was found in growth and development after the steel plate placement. Conclusion    Minimally invasive weaving technique is a safe, feasible, effective and individualized operation for pectus carinatum with substantial thoracic reconstruction.

OBJECTIVETo investigate the effect of early rehabilitation intervention on the incidences of extrauterine growth retardation (EUGR) and early diseases in preterm infants.

METHODSThe appropriate-for-gestational-age preterm infants with a gestational age of <34 weeks and a birth weight of 1 000 to <2 000 g who were admitted to the neonatal intensive care unit (NICU) within 24 hours after birth were enrolled in a prospective randomized controlled trial. These infants were randomly divided into rehabilitation intervention group and control group. The infants in the rehabilitation intervention group were given early rehabilitation after their vital signs became stable, including oral sensory and muscle strength training and pressure touching of the head, chest, abdomen, extremities, hands, and feet. The primary outcome measures were the time to independent oral feeding, length of hospital stay, and incidence rate of EUGR. The secondary outcome measures were the incidence rates of related diseases in preterm infants, such as apnea, feeding intolerance, and sepsis.

RESULTSA total of 97 preterm infants who met the inclusion criteria and had complete data were enrolled, with 48 in the control group and 49 in the rehabilitation intervention group. The rehabilitation intervention group had a shorter time to independent oral feeding than the control group (P<0.05). Compared with the control group, the rehabilitation intervention group had a shorter length of hospital stay and a lower corrected gestational age at discharge (P<0.05), as well as a lower incidence rate of EUGR (P<0.05). The rehabilitation intervention group ONCLUSIONS: Early rehabilitation intervention for preterm infants in the NICU may reduce the incidence rates of apnea, feeding intolerance, and EUGR and help them to achieve independent oral feeding early.

Background:Previous studies have found that schoolchildren with attention-deficit/hyperactivity disorder (ADHD) showed difficulties in neuropsychological function. This study aimed to assess neuropsychological function in Chinese preschoolers with ADHD using broad neuropsychological measures and rating scales and to test whether the pattern and severity of neuropsychological weakness differed among ADHD presentations in preschool children.

Methods:The 226 preschoolers (163 with ADHD and 63 controls) with the age of 4-5 years were included and assessed using the Behavior Rating Scale of Executive Function-Preschool Version (BRIEF-P) and a series of tests to investigate neuropsychological function.

ResultsPreschoolers with ADHD showed higher scores in all domains of the BRIEF-P (inhibition: 30.64 ± 5.78 vs.20.69 ± 3.86, P < 0.001; shift: 13.40 ± 3.03 vs.12.41 ± 2.79, P = 0.039; emotional control:15.10 ± 3.53 vs.12.20 ± 2.46, P < 0.001; working memory: 28.41 ± 4.99 vs.20.95 ± 4.60, P < 0.001; plan/organize: 17.04 ± 3.30 vs.13.29 ± 2.40, P < 0.001) and lower scores of Statue (23.18 ± 7.84 vs.28.27 ± 3.18, P = 0.001), Word Generation (15.22 ± 6.52 vs.19.53 ± 7.69, P = 0.025), Comprehension of Instructions (14.00 ± 4.44 vs.17.02 ± 3.39, P = 0.016), Visuomotor Precision (P < 0.050), Toy delay (P = 0.048), and Matrices tasks (P = 0.011), compared with normal control. In terms of the differences among ADHD subtypes, all ADHD presentations had higher scores in several domains of the BRIEF-P (P < 0.001), and the ADHD-combined symptoms (ADHD-C) group had the poorest ratings on inhibition and the ability to Plan/Organize. For neuropsychological measures, the results suggested that the ADHD-C group had poorer performances than the ADHD-predominantly inattentive symptoms (ADHD-I) group on Statue tasks (F = 7.34, η = 0.12, P < 0.001). Furthermore, the ADHD-hyperactive/impulsive symptoms group had significantly poorer performances compared to the ADHD-C group in the Block Construction task (F = 4.89, η = 0.067, P = 0.003). However, no significant group differences were found between the ADHD-I group and normal control.

Conclusion:Based on the combined evaluation of performance-based neuropsychological tests and the BRIEF-P, preschoolers with ADHD show difficulties of neuropsychological function in many aspects.
