Objective: To explore the effects of personality and sleep quality with psychological distress of junior and senior high school stduents, so as to provide a reference basis for precise interventions of junior and senior high school students mental health. Methods: In October 2023, a convenience sampling method was used to select 9 034 students aged 12-17 from Shiyan City as the study subjects. The Pittsburgh Sleep Quality Index (PSQI) and Kessler Psychological Distress Scale (K10) were used to collect information on sleep quality and psychological distress of junior and senior high school stduents. Between group comparison was conducted by using t-test and Chi-square test. Generalized linear models were employed to analyze the interaction and joint effects of personality and sleep quality on psychological distress. Results: The generalized linear model analysis showed that the interaction between personality and sleep quality on psychological distress was statistically significant of junior and senior high school students(effect size=0.80, P <0.01). The general linear model analysis indicated that, after adjusting for variables such as age, gender, screen time, and daily sitting time with the extroverted and good sleep quality group as the reference, the introverted and poor sleep quality group had the largest mean difference in psychological distress scores (difference=0.51, P <0.05). When stratified by sleep quality, psychological distress scores were higher in the introverted and neutral personality groups with both poor and good sleep quality compared to the extroverted group (poor sleep quality: introverted difference=3.71, neutral difference=1.14; good sleep quality: introverted difference=2.23, neutral difference=0.57, all P < 0.05). When stratified by personality, psychological distress scores were higher in the poor sleep quality groups for introverted, neutral, and extroverted individuals compared to their good sleep quality counterparts (differences=8.66, 7.83, 7.34, all P < 0.05 ). Conclusions Personality and sleep quality have interactive and joint effects on psychological distress of junior and senior high school stduents. Personalized psychological interventions should be developed based on personality and sleep quality.

Objective: To analyze the epidemiological characteristics of varicella among nursery children in Shenzhen from 2015 to 2024, and to evaluate the impact of optimizing varicella vaccine (VarV) immunization strategies on varicella incidence. Methods: Varicella incidence data for nursery children in Shenzhen from 2015 to 2024 were obtained from the China Disease Prevention and Control Information System. The study period was divided into three phases:one dose self pay VarV (January 2015 to October 2017), two dose self pay VarV (November 2017 to October 2019), and two dose free VarV (November 2019 to December 2024). Interrupted time series (ITS) analysis was conducted to assess changes in the level and trend of varicella incidence associated with each phase of policy implementation. Results: A total of 27 517 varicella cases was reported among nursery children from 2015 to 2024, with an average annual incidence of 514.01/100 000. During the same period, 136 clustered outbreaks were reported in nursery institutions, involving a cumulative total of 1 091 cases. ITS analysis showed that during the self pay 1 dose stage, the varicella incidence among nursery children showed an upward trend, with an average monthly increase of 2.58/100 000 (95% CI =2.21/ 100 000 -2.95/100 000, P <0.01). After the implementation of the self pay 2 dose strategy, the incidence decreased, with a change in incidence of -26.12/100 000 (95% CI =-37.30/100 000 to -14.94/100 000) and a change in slope of -2.65/100 000 (95% CI = -3.38/100 000 to -1.93/100 000)(all P <0.01). After the implementation of the free 2 dose strategy, the incidence decreased further, with a change in incidence of -40.03/100 000 (95% CI =-50.39/100 000 to -29.66/100 000, P <0.01) and a change in slope of -0.56/100 000 (95% CI =-1.20/100 000-0.08/100 000, P =0.09). Conclusion The gradual optimization of the VarV vaccination strategy in Shenzhen from self pay 1 dose to free 2 dose has significantly reduced the varicella incidence among nursery children, demonstrating good short term control and long term intervention effectiveness.

OBJECTIVE: To summarize the methods of ankle hinge position design in the correction of clubfoot deformity by Ilizarov method, and to explore its application value in the prevention of ankle dislocation. METHODS: A retrospective study was conducted including 28 patients with rigid clubfoot deformity (34 feet) who met the selection criteria and admitted between September 2021 and December 2024. There were 19 males and 9 females with an average age of 31.8 years (range, 19-47 years). According to Dimeglio classification, there were 21 feet of degree Ⅲ and 13 feet of degree Ⅳ. The causes were traumatic sequelae in 9 cases, congenital foot deformity in 15 cases, spina bifida sequelae in 1 case, peripheral neuropathy in 1 case, and cerebral palsy sequelae in 2 cases. The malformation lasted from 6 to 46 years, with an average of 29.3 years. All patients were treated with Ilizarov circular external fixator, and the hinge position of ankle joint was planned according to the standard lateral X-ray film of foot and ankle and the principle of Ilizarov limb deformity correction center of rotation angulation (CORA) before operation. The 2008 International Clubfoot Study Group (ICFSG) scoring system was used to evaluate the efficacy. RESULTS: The deformity of rigid clubfoot was completely corrected in all patients, and the patients could walk with plantar weight-bearing, and the ankle weight-bearing walking significantly improved when compared with that before operation. There was no complication such as ankle dislocation, talus impact or extrusion, local skin necrosis, needle tract infection, or numbness of extremities during the correction process. All patients were followed up 5-39 months, with an average of 18.1 months. At last follow-up, according to the ICFSG scoring system, 23 feet were excellent, 10 feet were good, and 1 foot was fair, and the excellent and good rate was 97%. CONCLUSION Designing the position of the ankle hinge according to the principle of CORA can effectively avoid ankle dislocation, talus impingement, tibiotalar joint extrusion, and other ankle adverse events in the process of correcting clubfoot deformity, which has good application value in clinical practice.

Osteoarthritis is a chronic degenerative disease characterized by cartilage degeneration, synovial inflammation, and subchondral bone remodeling. Its pathogenesis involves multiple links such as joint mechanical stress imbalance, extracellular matrix degradation, and inflammatory responses. Physical exercise has been widely recognized in the treatment of osteoarthritis. Although mechanism of action remains incompletely understood, appropriate exercise can effectively relieve pain caused by osteoarthritis, improve joint dysfunction, and reduce inflammation. In recent years, pyroptosis has been proven to exacerbate the pathological process of osteoarthritis by promoting the release of pro-inflammatory factors such as IL-1β and HMGB1 from synovial fibroblasts (FLSs) and chondrocytes. The pyroptosis of FLSs is regulated by the NLRP1/3 inflammasome, HIF-1α, and the SDF-1/AMPK pathway. In contrast, chondrocyte pyroptosis is closely related to the activation of the P2X7 receptor, the NF-κB/NLRP3 signaling axis, microRNAs (for example, miR-140-5p inhibits CTSB/NLRP3, while miR-155 promotes pyroptosis), and certain traditional Chinese medicine extracts (such as morroniside and loganin). Both exercise and pyroptosis are closely associated with the inflammatory response in osteoarthritis. Recent studies have found that exercise/mechanical stress stimulation can directly or indirectly regulate chondrocyte pyroptosis and delay the progression of osteoarthritis. In terms of direct regulation, moderate-intensity exercise can downregulate the expression of the P2X7 receptor, activate the AMPK/mTOR pathway to promote autophagy, and thereby inhibit chondrocyte pyroptosis. Mechanical stretch stimulation can upregulate TGF-β1 to activate the Smad2/3 pathway and inhibit the NF-κB/NLRP3 signaling axis. In terms of indirect regulation, exercise can inhibit the PI3K/Akt/NF-κB pathway by increasing the secretion of irisin, and simultaneously promote the production of lipoxin A4 (LXA4) to induce the polarization of synovial macrophages into the anti-inflammatory M2 type. In addition, exercise can also upregulate the expression of Metrnl protein and block the NLRP3/caspase-1/GSDMD pyroptosis signaling cascade.

Objective:To compare the efficacy of intranasal nebulized remimazolam versus esketamine for preoperative sedation in pediatric patients.Methods:In this randomized double-blind controlled trial, 90 pediatric patients scheduled for elective surgery with general anesthesia at Fuyang People′s Hospital between October 2024 and January 2025, were divided into 3 groups ( n=30 each) using a simple randomization: remimazolam group (group R), esketamine group (group S) and normal saline group (group C). Group R received intranasal nebulization of remimazolam 1.5 mg/kg, group S received intranasal nebulization of esketamine 1 mg/kg, and group C received intranasal nebulization of normal saline 0.05 ml/kg. Primary outcome: The preoperative anxiety was assessed using the modified Yale Preoperative Anxiety Scale before intranasal drug administration (baseline), at 10 and 20 min after administration, and before anesthesia induction. Secondary outcomes included sedation level (Ramsay Sedation Scale score), satisfaction with intranasal administration acceptance, parental separation anxiety and mask acceptance, development of emergence agitation, emergence time, time of recovery from anesthesia, and nausea and vomiting and increased secretions. Results:Compared to group C, the incidence of anxiety was significantly decreased at 10 and 20 min after intranasal nebulization and before anesthesia induction, the level of sedation was deepened (to light sedation), and the satisfaction with intranasal administration acceptance was decreased in group R ( P<0.017), the incidence of anxiety was significantly decreased before anesthesia induction, the level of sedation was deepened (to deep sedation), and the satisfaction with intranasal administration acceptance was increased in group S ( P<0.017), and the satisfaction with parental separation anxiety and mask acceptance and anesthesiologists′ satisfaction were significantly increased in R and S groups( P<0.017). Compared to group R, the incidence of anxiety was significantly increased at 10 min after intranasal nebulization (7 cases [23%] versus 20 cases [67%]), the level of sedation was lighter at 10 min after intranasal nebulization, the level of sedation was deeper, and the satisfaction with intranasal administration acceptance was increased in group S ( P<0.017). Compared to groups C and R, the emergence time and time of recovery from anesthesia were significantly prolonged in group S ( P<0.017). There was no significant difference in the incidence of emergence agitation, nausea and vomiting and increased secretions or in parental satisfaction among three groups ( P>0.05). Conclusions:Both intranasal nebulized remimazolam and esketamine can produce good preoperative sedation in pediatric patients. Compared to esketamine, remimazolam provides a more appropriate level of sedation with a faster onset and does not prolong the recovery from anesthesia, making it more suitable for preoperative sedation in minor procedures.

This article reviews the diagnosis, therapeutic approaches, and subsequent care for a patient with a complex, long-standing history of encapsulating peritoneal sclerosis (EPS). A 40-year-old male, who had been on peritoneal dialysis (PD) for 11 years, encountered refractory peritonitis, leading to the removal of PD catheter and the subsequent diagnosis of EPS. The patient was transitioned to hemodialysis (HD) and prescribed tamoxifen to mitigate peritoneal fibrosis. After 4 months on HD, the patient underwent a kidney transplant, but acute rejection episode caused the transplanted kidney to fail 3 months postoperatively, necessitating a return to HD. Over the past 7 years, the patient has been repeatedly hospitalized due to recurrent bowel obstructions and infected abdominal fluid accumulation. A multidisciplinary approach, including anti-infective therapy, gastrointestinal intervention, nutritional support, and psychological care, has been instrumental in managing symptoms, and sustaining life. This case underscores the importance of recognizing EPS in long-term PD patients with peritonitis. While discontinuing PD, switching to HD, or receiving kidney transplantation do not halt the progression of EPS, optimized comprehensive management can extend the patient's survival.

Objective:To investigate the relationship between lipid levels and cognitive impairment in the elderly Chinese population using prospective cohort data.Methods:Based on the China-PAR (Prediction for Atherosclerotic Cardiovascular Disease Risk in China) cohort, this study included 24 380 individuals aged ≥60 years who participated in the cognitive function follow-up survey from 2018 to 2019. Cognitive function was assessed using the Mini-Mental State Examination (MMSE), with cognitive impairment defined according to different educational levels: MMSE ≤17 for illiterate individuals, MMSE ≤20 for those with primary education and MMSE ≤24 for those with secondary education or above. Multivariable linear regression and logistic regression models were employed to examine the associations between six baseline lipid indicators and cognitive scores, as well as cognitive impairment. Additionally, restricted cubic splines were used to explore the exposure-dose relationship between lipid levels and cognitive function.Results:The study population had a median follow-up time of 11.6 years, with a baseline age of (59.7±6.8) years. Among the participants, 9 510 (39.0%) were males, and the mean MMSE score was 24.7±6.8. A total of 3 887 individuals (15.9%) were identified as cognitively impaired. The results of multivariable linear regression and logistic regression indicated that total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C) and non-high-density lipoprotein cholesterol (non-HDL-C) levels were not only significantly positively associated with cognitive scores but also significantly associated with a lower risk of cognitive impairment. Each 1 mmol/L increase in these lipid levels corresponded to β values (95% CI) of 0.267 (0.173-0.361), 0.385(0.271-0.499) and 0.331(0.231-0.431), respectively. Each 1 mmol/L increase in these lipid levels corresponded to odds ratio ( OR) (95% CI) values of 0.915 (0.876-0.956), 0.875 (0.830-0.923) and 0.886 (0.848-0.927), respectively. The dose-response curve demonstrated that the negative association was primarily observed within the guideline-recommended optimal lipid level range. Specifically, when LDL-C was less than 3.4 mmol/L and non-HDL-C was less than 4.1 mmol/L, the corresponding OR (95% CI) values were 0.859 (0.796-0.926) and 0.876 (0.818-0.939). Conclusion:Lipid levels exhibit a certain linear negative association with cognitive impairment in elderly Chinese adults, with LDL-C and non-HDL-C demonstrating a stronger effect, particularly within the guideline-recommended optimal range.

Parkinson′s disease (PD) is the second most common neurodegenerative disease. It is particularly important to find biomarkers with high sensitivity and specificity to capture the early features and evolution of the disease. As motor symptoms are the core symptomatic manifestation of PD and subtle changes in motor function occur early in the disease, the objectivity and broad applicability of digital devices make them ideal for screening and monitoring changes in motor function during the development of PD. Digital biomarkers related to motor symptoms in the diagnosis and monitoring of PD are reviewed in this article, with a view to providing some references for the clinical diagnosis and treatment of the disease.

Objective To observe the analgesic and rehabilitation effects of non μ-opioids anesthesia/analgesia(NΜOA)based on quadratus lumborum block(QLB)in emergency cesarean section under general anesthesia.Methods The retrospective study method was adopted,50 pregnant women undergoing hysterectomy under emergency general anesthesia in Langfang People's Hospital from January 2023 to December 2024 were selected as the study objects.The patients were divided into μ-opioids anesthesia/analgesia(ΜOA)group and NΜOA group according to different anesthesia/analgesia methods,25 cases in each group.ΜOA group received ΜOA;NΜOA group received NΜOA+QLB.Incisional pain and uterine contraction pain numerical rating scale(NRS)at out of the post-anesthesia care unit(T1),intravenous injection of oxytocin(T2),press the palace bottom 24 hours(T3),out of bed activity after operation(T4)and first analgesic time of incision pain,first analgesic time of uterine contraction pain,first no vomiting eating time,first exhaust time was observed and recorded.The incidence of vasoactive agents during the anesthetic period,rescue analgesia,rescue antiemetic,constipation,sleep disturbance after operation within 48 hours after operation were also recorded.Results The NRS scores at T1,T2,T3 and T4 in ΜOA group were significantly higher than those in NΜOA group(incisional pain 3.36±1.25 vs.1.12±0.97,3.68±1.18 vs.2.00±0.91,5.76±1.67 vs.4.20±1.00,4.48±1.29 vs.3.32±0.95;uterine contraction pain 3.72±1.49 vs.1.24±1.05,4.64±1.60 vs.3.04±1.27,7.56±1.71 vs.5.16±1.37,3.56±0.22 vs.2.56±0.16,all P<0.05).The first analgesic time of incision pain,first analgesic time of uterine contraction pain in ΜOA group were significantly less than that in NΜOA group(hours:3.06±2.02 vs.17.48±10.93,2.68±2.22 vs.15.80±11.39,both P<0.05),the first no vomiting eating time,first exhaust time in ΜOA group were significantly longer than those in NΜOA group(hours:8.56±0.57 vs.6.32±0.14,15.44±1.42 vs.10.16±1.14,both P<0.05),the incidence of vasoactive agents,rescue analgesia,rescue antiemetic,constipation,sleep disturbance after operation within 48 hours in ΜOA group were significantly higher than those in NΜOA group[64.0%(16/25)vs.32.0%(8/25),48.0%(12/25)vs.20.0%(5/25),44.0%(11/25)vs.16.0%(4/25),64.0%(16/25)vs.36.0%(9/25),60.0%(15/25)vs.32.0%(8/25),all P<0.05].Conclusion NΜOA based on QLB safely and effectively reduced side effects of μ-opioids and enhanced recovery compared to ΜOA on emergency cesarean section patients undergoing general anesthesia.

Objective: To explore the clinical manifestations and treatment plans of chronic recurrent parotitis (CRP), and to provide a reference for the clinical diagnosis and treatment of CRP. Methods: Approval was obtained from the hospital’s Medical Ethics Committee, and a retrospective analysis and summary of the clinical features, imaging characteristics, diagnosis, and treatment of 41 CRP patients with complete data were performed. Results: Among the 41 patients with CRP, 14 were male and 27 were female, with a male-to-female ratio of approximately 1:2 (14/27). The age at first-time onset ranged from 3 to 23 years, with a median age of 6 years, and there were 38 patients (92.7%, 38/41) with the first onset age of under 18 years old. The age of the first visit to our hospital ranged from 4 to 72 years old, with an average age of (41.0 ± 17.3) years; the disease duration was 0.5 to 66 years, with an average of 35.0 ± 16.1 years. Twenty-five cases had bilateral parotid gland involvement (61.0%, 25/41). The clinical manifestations of CRP are repeated swelling of one or both parotid glands, along with discomfort, and this may be accompanied by mild edema or skin flushing and pus or jelly-like secretions at the duct openings. The typical manifestations of parotid angiography are: the dominant duct and branch ducts of the parotid gland do not have specific dilation or narrowing, and the peripheral ducts show characteristic “punctate, spherical, or cavitary” dilation and delayed emptying. Of the cases, 34 had abnormal enlargement of the main duct orifice (82.9%, 34/41), and 37 presented with abnormal anterior displacement of the accessory glands (90.2%, 37/41). The treatment plan of “antibiotic perfusion + aspiration and removal of obstruction (or aspiration after obstruction dissolution)+ postprandia massage along the direction of the parotid duct (from posterior to anterior) with multiple courses for consolidation”achieved favorable outcomes. The mean follow-up period of this group was(71.1+21.9)months, and no recurrence was observed during the follow-up period. Conclusion CRP is more prevalent in young females and frequently presents with bilateral involvement. Congenital anatomical defects, such as abnormal enlargement of the main duct orifice and abnormal anterior displacement of the accessory glands, are important predisposing factors. The multi-course comprehensive therapy centered on antibiotic infusion, removal and dissolution of obstructions, and post-prandial massage along the direction of the parotid duct has significant therapeutic effects and deserves clinical application.
