Under the trend of increasing aging， integrated elderly care and medical services is an important measure to optimize the supply of elderly care services and promote the good death of the elderly. Using the cooperative production theory and the classical grounded theory， a qualitative analysis was conducted on 38 cases of elderly palliative care and 25 cases of hospital-based palliative care under the integrated elderly care and medical services model from a hospital in Nanning City using Nvivo 20.0 software. This paper found that the integrated elderly care and medical services mode emphasized the deep integration of medical and elderly care services by integrating resources and improving service efficiency， to achieve the basic experience of comprehensive health care for the elderly. The promotion of these experiences has a positive significance for building a multi-agent cooperative production system， strengthening personnel training， perfecting the performance distribution mechanism， and further promoting the development of the national palliative care pilot.

Objective:To identify the risk factors for postoperative sleep disturbance (PSD) in patients undergoing spine surgery.Methods:In this case-control study, patients who underwent spine surgery from December 2023 to June 2024 at Beijing Tiantan Hospital of Capital Medical University, were selected as the subjects of the study. The quality of postoperative sleep was assessed using the Athens Insomnia Scale (AIS). The baseline characteristics and various perioperative indicators of the patients were collected. The patients were divided into PSD group and non-PSD group according to whether they had PSD. The variables with statistically significant differences from the univariate analysis were included in a multivariate logistic regression to identify the risk factors for PSD.Results:The results of the multivariate logistic regression analysis showed that preoperative sleep disturbance (odds ratio [ OR]=2.23, 95% confidence interval [ CI] 1.06-4.72, P=0.036), course of disease > 12 months ( OR=2.20, 95% CI 1.14-4.24, P=0.019) and AIS score > 2 on the night before surgery ( OR=2.06, 95% CI 1.02-4.16, P=0.045) were the independent risk factors for PSD in patients undergoing spine surgery. Conclusions:Preoperative sleep disturbance, course of disease > 12 months and AIS score > 2 on the night before surgery are independent risk factors for PSD in patients undergoing spine surgery.

Objective To establish a quality standard for the medicinal bath formula for treating exogenous fever(composed of Forsythiae Fructus,Peucedani Radix,Schizonepetae Spica,Isatidis Radix,Gypsum Fibrosum,Chrysanthemi Flos,Lophatheri Herba,etc.)based on its efficacy and indications.Methods Thin-layer chromatography(TLC)was used to establish identification method for the monarch drugs Forsythiae Fructus and Peucedani Radix.Enzyme-linked immunosorbent assay(ELISA)was employed to measure the interleukin 1β(IL-1β)regulatory activity of the main components in the formula.High-performance liquid chromatography(HPLC)was used to determine the content of active components in 10 batches of samples.Results Spots of Forsythiae Fructus and Peucedani Radix were successfully detected in the test samples.ELISA identified active components in the formula,including praeruptorin A,pulegone,rutin,praeruptorin B,forsythoside,and(R,S)-goitrin.The content determination results of 10 batches of samples showed that the content of praeruptorin A ranged from 0.493 to 0.694 mg·mL-1.Conclusion Based on its efficacy and indications,TLC identification and HPLC content determination methods were established for the medicinal bath formula for treating exogenous fever.The obtained standard can more accurately control the efficacy of the formula.

Objective To explore the effect of sugammadex on safety indicators such as body movement,choking,peak airway pressure during spinal surgery with motor evoked potential monitoring.Methods This study was a ret-rospective analysis of two randomized controlled trials.Patients undergoing selective thoracic and lumbar spinal sur-gery with intraoperative motor evoked potential monitoring were included.Rocuronium was continuously infused and the train-of-four stimulation count was maintained at 2.When motor evoked potential monitoring started,stop rocu-ronium infusion and 2 mg/kg of sugammadex was given.Indicators were compared between administration of sugam-madex and 5,10,20,30,60 minutes after administration like body movement,choking,peak airway pressure,allergic reaction,mean arterial pressure,heart rate,end expiratory pressure of CO2 and the train-of-four stimulation ratio(TOFr).Results A total of 120 patients were finally included in the analysis.Before administering sugammadex,TOFr was 0.2.At 5,10,20,30 and 60 minutes after administration,TOFr were 0.8,0.8,0.9,0.9,0.9 respectively.No patient experienced intraoperative body movement,choking,or allergy reaction.Compared with the time of sugamma-dex administration,heart rate was significantly reduced 5,10,20,30 and 60 minutes after administration(P＜0.05),there was no significant change in the remaining indicators.Conclusions Sugammadex can be safely used during spinal surgery with motor evoked potential monitoring.

Objective To explore the neurophysiological signatures of auditory event-related potentials(AERP)during propofol-induced graded sedation depths,and their correlations with sedation levels and behavioral responsiveness,and further to evaluate the feasibility of AERP components as potential biomarkers for quantifying consciousness states.Methods An auditory Oddball paradigm was used to evoke AERP responses in healthy volunteers under propofol-induced graded sedation.Linear mixed model was applied to explore the relationships between the mean amplitudes of AERP components[mismatch negativity(MMN);P300]and both sedation-induced conscious states[Modified Observer's Assessment of Alertness/sedation Scale(MOAA/S)scores]and behavioral performance(response accuracy).Results Twenty-two healthy volunteers were included.Data analysis revealed significant negative correlations between the mean amplitudes of MMN components[MMN-Dev:β=-0.62(-2.70--0.07),P=0.04;MMN-Nov:β=-0.15(-0.27--0.03),P=0.02]and MOAA/S scores during propofol sedation.Novel stimulus-evoked MMN amplitudes also correlated with response accuracy[MMN-Nov:β=-5.08(-7.78--2.37),P<0.01].There was a weak positive correlation between novel stimulus-evoked P300 amplitudes and MOAA/S scores[β=0.16(0.04-0.39),P=0.04],however,the correlation was no significant difference after adjusting for confounding factors including age,education level,and cognitive level.Conclusion The mean amplitude of MMN component elicited during auditory tasks was correlated with conscious states and behavioral accuracy under propofol-induced graded sedation.MMN holds promise as a potential neurophysiological indicator for quantifying conscious states or behavioral responsiveness during sedation.

Objective:To investigate the levels of chemokine 2 (CCL2), chemokine (C-X-C motif) ligand 1 (CXCL1), chemokine (C-X3-C motif) ligand 1 (CX3CL1), and chemokine (C-X-C motif) ligand 10 (CXCL10) in the cerebrospinal fluid of patients with acute and chronic herpes zoster (HZ), and their correlation with the severity of neuropathic pain.Methods:A total of 60 patients with acute herpes zoster and postherpetic neuralgia (PHN) treated at the First Affiliated Hospital of Zhengzhou University from November 2022 to November 2023 were selected for a case-control study. These patients were divided into a HZ group ( n = 25) and a PHN group ( n = 35). The pressure pain threshold in the affected area was measured on the day of admission for all patients. The Visual Analogue Scale scores were evaluated in both groups. After lumbar puncture, 2 mL of cerebrospinal fluid was collected, and the levels of related chemokines in the cerebrospinal fluid were detected using the enzyme-linked immunosorbent assay. Results:In the HZ group, the levels of chemokines CXCL1 and CXCL10 were (24.84 ± 6.97) ng/L and (107.46 ± 28.29) μg/L, respectively, while in the PHN group, they were (20.51 ± 3.16) ng/L and (132.98 ± 30.92) μg/L. The differences in the levels of chemokines CXCL1 and CXCL10 between the two groups were statistically significant ( t = 2.91, -3.26, both P < 0.05). There were no statistically significant differences in the levels of chemokines CCL2 and CX3CL1 between the two groups ( t = 1.62, -0.23, both P > 0.05). The levels of CCL2, CXCL1, CX3CL1, and CXCL10 in both groups were negatively correlated with the pressure pain threshold (HZ group: r = -0.84, -0.78, -0.93, -0.86; PHN group: r = -0.71, -0.78, -0.94, -0.76, all P < 0.01). Conclusion:Higher levels of chemokines in the cerebrospinal fluid of patients with acute and chronic HZ are associated with more pronounced neuropathic pain. The neuro-immune inflammation involving chemokines may be correlated with the severity of neuropathic pain in acute and chronic HZ.

Objective:To investigate the association between visceral adipose tissue (VAT) thickness in early pregnancy and the risk of gestational diabetes mellitus (GDM).Methods:Based on the Qingdao Women and Children Health Cohort, pregnant women in the first trimester (11-13 +6 weeks of gestation) were enrolled in this cohort study between May 2019 and October 2022. The VAT was measured in first trimester and determined as the distance from the inner margin of the rectus abdominis muscle to the anterior wall of the great artery using multi-functional color ultrasound. The 75 g oral glucose tolerance test (OGTT) results were followed up at 24-28 weeks and the participants were divided into GDM group and non-GDM group. The pregnant women were divided into 4 groups according to the VAT quartile. Log-binomial model and linear regression model were used to analyze the association between VAT and GDM/blood glucose. Results:A total of 3 686 pregnant women were included in this study, the mean age of participants was (30.56±4.05) years and 722 were diagnosed with GDM, with an incidence of 19.6%. The log-binomial regression model results showed that compared with VAT thickness Q1 (VAT<14.70 mm), the GDM risk in Q3 (21.65≤VAT≤29.69 mm) and Q4 (VAT ≥29.70 mm) increased by 34% [ RR(95% CI): 1.34 (1.08-1.67)], and 61% [ RR(95% CI): 1.61 (1.30-2.00)], respectively. Among women with gestational age<35 years old, compared with VAT thickness Q1, the risk of GDM increased by 42% in Q3 [ RR(95% CI): 1.42 (1.22-1.65)] and 70% [ RR(95% CI): 1.70 (1.46-1.98)] in Q4, whereas no associations were found in women with gestational age ≥35 years old ( P>0.05). The association between VAT and GDM risk was only found in pregnant women with pre-pregnancy BMI <24.0 kg/m 2, and the GDM risk increased by 57% [ RR(95% CI): 1.57 (1.22-2.04)] in Q3 and 65% [ RR(95% CI): 1.65 (1.24-2.19)] in Q4 compare with Q1. The results of multiple linear regression analysis showed that VAT was positively correlated with fasting blood glucose, 1-hour blood glucose after 75 g OGTT and 2-hours blood glucose after 75 g OGTT (all Pfor trend<0.001). Conclusion:High VAT thickness in early pregnancy is an independent risk factor for GDM, and the GDM risk increases with the raising of VAT depth.
