Objective:To determine the clinical issues in the Clinical practice guidelines for postoperative pain management in adults (2024 edition). Methods:A preliminary list of clinical issues for the guidelines was developed through literature review, clinical surveys, and expert interviews. This was followed by two rounds of Delphi questionnaire surveys, with quality control and statistical analysis conducted using expert positive coefficient, mean item scores, full score ratio, coefficient of variation, Cronbach′s α coefficient, and expert authority level to finalize the list of clinical issues.Results:The experts participating in the Delphi questionnaire surveys had multidisciplinary collaborative backgrounds and regional representativeness, with a high level of authority. The overall positive coefficient of expert participation in the surveys was 78.9%. Through two rounds of the Delphi method and based on the screening criteria of a mean score ≥3.5, coefficient of variation ≤30%, and full score ratio ≥30%, 17 clinical issues were ultimately included following an expert consensus meeting.Conclusions:Through the Delphi method and rigorous quality control, the clinical issues in the Clinical practice guidelines for postoperative pain management in adults (2024 edition) are determined, laying a foundation for the subsequent development of the guidelines.

Objective:To investigate the value of carotid，radial and podalic artery intima thickness（CIT，RIT，PIT）combined with monocyte to high-density lipoprotein ratio（MHR）in predicting the severity of coronary artery stenosis in patients with premature coronary artery disease（PCAD）.Methods:A total of 80 patients with PCAD who received treatment in Henan Provincial People's Hospital from October 2023 to May 2024 were prospectively recruited，and they were divided into high group（≥41 score，40 cases）and low group（＜41 score，40 cases）according to the median dichotomy of Gensini score. Thirty-four gender，age and body mass index（BMI）-matched healthy volunteers were selected as the control group. The CIT，RIT，PIT，media and intima media thickness of carotid，radial artery and podalic artery（CMT，RMT，PMT，CIMT，RIMT，PIMT）were measured using 24 MHz ultra-high frequency ultrasound probe，and the ratio of intima to media thickness（CIT/CMT，RIT/RMT，PIT/PMT）was calculated. The differences of general clinical data，laboratory indexes and ultrasonic parameters among the three groups were compared. Risk factors affecting the severity of coronary stenosis in PCAD patients were explored by binary logistic regression. Subject working characteristic curves were plotted，area under the curve（AUC）was calculated，and the values of each ultrasound parameter and MHR in the independent and combined diagnosis of the severity of coronary artery stenosis in PCAD patients were evaluated.Results:①There were no statistically significant differences in age，gender，BMI，total cholesterol，CMT，RMT and PMT among the three groups（all P＞0.05）. There were no statistically significant differences in the comparison of smoking，hypertension，diabetes mellitus，systolic blood pressure，diastolic blood pressure，low-density lipoprotein cholesterol，total cholesterol，and triglycerides between the two subgroups of the PCAD（all P>0.05）. ②CIT，CIMT，CIT/CMT，RIT，RIMT，RIT/RMT，PIT，PIMT，PIT/PMT were thickened in the high group compared with the low group，and MHR was higher than in the low group（all P<0.05），the differences in the above parameters remained statistically significant when comparing the PCAD group with the control group（all P<0.05）. ③The AUC values for MHR，CIT，RIT and PIT alone to predict the severity of coronary stenosis in patients with PCAD were 0.781，0.767，0.780 and 0.722，respectively. The combined diagnostic efficiency of the four parameters was better than the independent diagnostic efficiency（AUC = 0.885）. Conclusions:CIT，RIT and PIT are thicker in PCAD patients with high Gensini score and the combination of artery intima thickness and MHR has good efficacy in predicting the severity of coronary artery stenosis in PCAD patients.

Objective:To evaluate the changes of carotid intima thickness（CIT）and stiffness parameters in ankylosing spondylitis（AS）patients by 24 MHz ultra-high frequency ultrasound probe and RF-data based quantitative analysis on vessel stiffness（R-VQS），and to explore its influencing factors.Methods:Sixty patients with AS who underwent consultation at Henan Provincial People's Hospital from November 2023 to May 2024 were prospectively collected as AS group，54 healthy volunteers matched for sex，age，and body mass index were collected as control group. CIT were measured using a 24 MHz ultra-high frequency ultrasound probe，hardness coefficien（HC）and pulse wave velocity（PWV）were measured by R-VQS，the differences of the parameters between the two groups were compared. The changes of carotid artery elasticity and intima thickness and their influencing factors in patients with AS were explored by univariate and multivariate linear regression analysis.Results:①C-reactiveprotein，erythrocyte sedimentation rate（ESR），neutrophil count and neutrophil to lymphocyte ratio（NLR）were elevated in the AS group compared with the control group，and the differences were statistically significant（all P < 0.05）. ②CIT，carotid intima-media thickness（CIMT），HC，PWV and epicardial adipose tissue thickness（EATT）were all increased in the AS group compared with the control group，and the differences were statistically significant（all P < 0.05）. ③Multifactorial linear regression analysis showed that EATT，ESR were the main influencing factors of HC，PWV and CIT（ β=2.192，0.031；1.792，0.002；0.097，0.001；all P＜0.05）. Conclusions:Carotid CIT，CIMT，HC，PWV and EATT are all higher in the AS patients，and ESR and EATT are the main influencing factors of HC，PWV，and CIT，suggesting that more attention should be paid to the detection of ESR and EATT in patients with AS when interventions are performed clinically.

Objective:To compare the efficacy of the transverse process-lateral pedicle approach and curved vertebroplasty in the treatment of osteoporotic vertebral compression fracture (OVCF).Methods:A retrospective cohort study was conducted to analyze the clinical data of 66 patients with OVCF admitted to the Second People′s Hospital of Hefei from December 2021 to June 2023, including 9 males and 57 females aged 60-89 years [(75.6±7.5)years]. The injured segments included T 11 in 17 patients, T 12 in 17, L 1 in 17, and L 2 in 15. Among them, 33 patients underwent vertebroplasty via the transverse process-lateral pedicle approach (lateral approach group), while other 33 patients underwent curved vertebroplasty (curved group). The surgical duration, number of X-ray fluoroscopy, bone cement injection volume, and length of hospital stay were compared between the two groups. Additionally, the restoration efficiency of vertebral height and the correction degree of spinal scoliosis Cobb angle at 2 days postoperatively were compared between the two groups. The changes in serum levels of stress factors including noradrenaline, adrenaline, and cortisol preoperatively and at 2 days postoperatively, the visual analogue scale (VAS) and Oswestry disability index (ODI) preoperatively, at 2 days, 6 months postoperatively, and at the last follow-up were compared between the two groups. The incidence of complications was assessed in the two groups. Results:All the patients were followed up for 12-14 months [(13.2±0.5)months]. The surgical duration and number of X-ray fluoroscopy in the lateral approach group were (30.9±4.1)minutes and (5.9±3.3)times, which were significantly lower than (35.8±3.9)minutes and (9.9±4.4)times in the curved group ( P<0.01). There were no statistically significant differences between the two groups in terms of bone cement injection volume, length of hospital stay, restoration efficiency of vertebral height at 2 days postoperatively, or the correction degree of spinal scoliosis Cobb angle ( P>0.05). The levels of noradrenaline, adrenaline, and cortisol at 2 days postoperatively were (57.3±4.8)ng/ml, (49.9±4.2)ng/ml, (159.3±20.5)nmol/L in the lateral approach group, and (64.3±4.5)ng/ml, (58.3±4.4)ng/ml, (183.5±21.2)nmol/L in the curved group, which were all significantly increased compared with those preoperatively [(42.3±3.5)ng/ml, (38.5±2.8)ng/ml, (128.4±12.3)nmol/L in the lateral approach group and (42.0±3.5)ng/ml, (39.0±3.0)ng/ml, (128.5±12.3)nmol/L in the curved group] ( P<0.01). There were no significant differences between the two groups in terms of the levels of noradrenaline, adrenaline, and cortisol preoperatively ( P>0.05). The levels of noradrenaline, adrenaline, and cortisol at 2 days postoperatively in the lateral approach group were significantly lower than those in the curved group ( P<0.01). The VAS scores for low back pain in the lateral approach group and the curved group were 3(2, 5)points and 5(3, 6)points at 2 days postoperatively, 3(2, 4)points and 3(2, 4)points at 6 months postoperatively, and 2(2, 3)points and 2(2, 4)points at the last follow-up, which were all significantly lower than those preoperatively [7(7, 9)points and 8(6, 9)points] ( P<0.05). Moreover, the VAS scores for low back pain were further decreased over time postoperatively ( P<0.05). The ODI values in the lateral approach group and curved group were (33.4±4.4)% and (33.7±4.3)% at 2 days postoperatively, (23.8±1.6)% and (23.8±1.7)% at 6 months postoperatively, and (15.6±0.9)% and (15.6±0.9)% at the last follow-up, which were all significantly lower than (67.4±4.3)% and (67.5±4.3)% preoperatively ( P<0.05). Moreover, the ODI values were further decreased over time postoperatively ( P<0.05). There were no significant differences between the two groups in terms of the VAS scores for low back pain or ODI values preoperatively, at 2 days, 6 months postoperatively or at the last follow-up ( P>0.05). The complication rate was 12.1% (4/33) in the lateral approach group, which was significantly lower than 51.5% (17/33) in the curved group ( P<0.05). Conclusion:Although both the transverse process-lateral pedicle approach vertebroplasty and the curved vertebroplasty can achieve good therapeutic effects in the treatment of OVCF, the former has shorter surgical duration, fewer times of X-ray fluoroscopy, lower trauma stress levels at 2 days postoperatively, and fewer complications.

Objective:To investigate the relationship between daily physical exercise and frailty state among elderly inpatients in internal medicine department.Methods:A cross-sectional study was conducted among eligible elderly patients who hospitalized at the internal medicine department of Beijing Hospital from September 2018 to March 2019.Frailty was screened using the FRAIL scale, and their pre-hospitalization daily physical exercise was assessed through a questionnaire upon admission.The statistical methods include correlation analysis and logistic regression univariate and multivariate analysis.Results:A total of 533 eligible elderly patients in internal medicine were included in the study, with 129(24.2%)frail, 296(55.5%)pre-frail, and 108(20.3%)non-frail patients.328 patients(61.5%)exercised more than 5 times a week, while 102 patients(19.1%)hardly exercised at all.Physical exercise frequency had negative correlation with the FRAIL frailty score( r=-0.576, P<0.001).Both univariate and multivariate logistic regression analysis shown daily physical exercise frequency was significantly associated with frailty( OR=0.56, 95% CI: 0.49-0.65, P<0.001)among elderly inpatients in internal medicine. Conclusions:For elderly inpatients in internal medicine department, daily physical exercise frequency is closely related to frailty status, serving as an independent factor in reducing the occurrence of frailty.Therefore, increasing the frequency of daily physical exercises is an effective measure to reduce the risk of frailty for this group of patients.

Objective To establish and evaluate an integrated disease-syndrome rat model of chronic cerebral ischemia with Qi deficiency and blood stasis syndrome.Methods Thirty male Wistar rats were allocated randomly into three groups(n=10 per group):sham operation(sham),2-vessel occlusion(2-VO)group,and sleep deprivation combined with 2-VO(SD+2-VO)group.We comprehensively assessed Qi deficiency and blood stasis syndrome manifestations in the rats using a dual evaluation approach,combining exhaustive swimming tests with quantitative tongue chroma analysis.Cognitive function was evaluated using the Barnes maze,and cerebral blood flow was compared using laser speckle contrast imaging.The histopathology of the hippocampal cytoarchitecture and white matter were examined using hematoxylin-eosin(HE)and Luxol fast blue(LFB)staining,respectively,and ultrastructural alterations of neurons in the hippocampal CA1 region were observed by transmission electron microscopy(TEM).Protein expression levels of NeuN,vascular endothelial growth factor A(VEGFA)and CD31 were detected by Western Blot and immunofluorescence.Results Cerebral blood flow was significantly reduced in rats in the 2-VO group compared with the sham group,but they failed to recapitulate the key clinical hallmarks of Qi deficiency and blood stasis syndrome.In contrast,rats in the SD+2-VO group exhibited significantly reduced locomotor activity,exacerbated cerebral hypoperfusion,shortened swimming duration,and darkened tongue color compared with 2-VO rats.Rats in the SD+2-VO group demonstrated significantly impaired learning and memory abilities in the Barnes maze test.Consistent with these observations,HE staining,TEM,and LFB staining revealed substantial neuronal and white matter damage in the SD+2-VO group.NeuN expression was decreased and VEGFA and CD31 expression levels were increased in the 2-VO and SD+2-VO groups,as shown by Western Blot.Taken together,these findings indicated that the SD+2-VO model effectively recapitulated the clinical features of chronic cerebral ischemia with Qi deficiency and blood stasis pattern.Conclusions The combination of sleep deprivation and bilateral carotid artery occlusion successfully established a rat model of chronic cerebral ischemia with Qi deficiency and blood stasis syndrome.Compared with the 2-VO model,SD+2-VO model demonstrates more pronounced syndrome manifestations and better clinical relevance,thus providing a valuable animal model for traditional Chinese medicine research on chronic cerebral ischemia.
