Pain is one of the most common symptoms in cancer patients. Apart from causing patients to suffer from unpleasant feelings and negative emotional experiences, uncontrolled pain may also influence patients' function and quality of life, and may be associated with poorer prognosis. Poor management of chronic cancer-related pain may be related to its complicated mechanisms, limitations of current clinical treatment and clinicians' and patients' insufficient understanding of the symptom. Therefore, this review summarizes the definitions, classifications, evaluation and treatment principles of chronic cancer-related pain, and emphasises the importance of multidisciplinary management and patient education in cancer pain management to provide clinicians with the overall idea of pain management in adult cancer patients.

Objective To investigate the expression level and clinical significance of cyclic citrullinated peptide antigen-specific T cells(CCP/AST)in synovial fluid and synovial tissue of rheumatoid arthritis(RA)patients.Methods A total of 128 RA patients in Shijiazhuang Hospital of Traditional Chinese Medicine from January to December 2021 were selected as the RA group,and 50 patients who needed arthroscopy for joint pain in the hospital during the same period were selected as the control group.Among the RA group,there were 46 cases in the mild group,52 cases in the moderate group,and 30 cases in the severe group.The protein expression levels of rheumatoid factors(RF)and anticitrullinated protein antibodies(ACPA)in synovial tissues of the subjects in each group were analyzed by Western blot.The frequency of CCP/AST in the synovial fluid of the subjects was analyzed by flow cytometry.The intensity of the staining of CCP/AST in synovial tissues was observed by double immunofluorescence staining/laser confocal scanning.Pearson correlation analysis was used to assess the correlation between the CCP/AST expression of synovial fluid and synovial tissue and RF and ACPA.Logistic regression was used to analyze the risk factors for the development of rheumatoid arthritis.Results In the order of control,mild,moderate and severe groups,RF(1.01±0.01,1.53±0.03,2.01±0.08,2.66±0.12 kDa)and ACPA proteins(1.03±0.01,1.61±0.03,2.04±0.10,2.59±0.13 kDa)in synovial tissues of patients were sequentially elevated,and the differences were all statistically significant(F=14.207,12.446,all P＜0.05).The expression of CCP/AST in synovial fluid of patients in the control,mild,moderate and severe groups was increased sequentially(8.26%±1.68%,22.46%±3.28%,33.58%±4.37%,46.15%±5.44%),and the difference was statistically significant(F=25.306,P＜0.05).Meanwhile,the intensity of CCP/AST staining in synovial tissues of patients in the control,mild,moderate and severe groups was also increased sequentially(1.05±0.26,1.35±0.89,2.04±0.56,2.78±0.15 score),and the difference was statistically significant(F=70.67,P＜0.05).The expression of CCP/AST in the synovial fluid and synovial tissues of patients with RA was positively correlated with RF(r=0.861,0.934,all P＜0.05)and ACPA in synovial fluid and synovial tissue(r=0.854,0.913,all P＜0.05).Logistic regression analysis showed that hypertension(OR=3.241,95%CI:1.491～6.752),diabetes mellitus(OR=2.565,95%CI:1.126～5.813),synovial fluid(OR=4.450,95%CI:1.652～11.622),and CCP/AST expression in synovial tissues(OR=5.629,95%CI:2.474～12.390)were independent risk factors for the development of RA(P＜0.05).Conclusion CCP/AST showed high expression in synovial fluid and synovial tissue of RA patients and related to disease activity and joint destruction,which can be used to assess the clinical joint mobility and bone destruction degree in such patients.

OBJECTIVE To explore the potential mechanism of the effect of Xuebijing injection （XBJ） on neurological function and survival of rats after cardiac arrest （CA）/cardiopulmonary resuscitation （CPR） based on the S-nitrosoglutathione reductase （GSNOR）/S-nitrosoglutathione （GSNO） pathway. METHODS The CA/CPR rat model was established by ventricular fibrillation. Using a sham operation group as control， high-throughput sequencing was employed to analyze and mine the differentially expressed genes （DEGs）. Enzyme-linked immunosorbent assay was used to determine the contents of GSNOR and GSNO in the hippocampus； the active components of XBJ were screened and subjected to molecular docking analysis with GSNOR. The rats successfully modeled using the same method were divided into model group （n＝30）， inhibitor （GSNOR inhibitor） group （n＝30）， XBJ group （n＝30） and XBJ+inhibitor group （n＝30）， and a sham operation group （n＝30） was set up. Neurological function was evaluated and survival status was recorded at 3 hours， 24 hours and 3 days after the first 89） drug intervention. The contents of GSNOR and GSNO in the hippocampus of rats were determined in each group at the 0191） above time points， and the relationship of the contents of GSNOR and GSNO with modified neurologic severity scale （mNSS） score was analyzed. RESULTS GSNOR coding gene was differentially expressed between the model group and the sham operation group. Compared with the sham operation group， GSNOR content increased significantly in the hippocampus of rats in model group， while GSNO content decreased significantly （P＜0.05）. The active components of XBJ， such as 4- methylenemiltirone and salviolone， could be bound to GSNOR protein， with the binding energy lower than －6 kcal/mol， mainly connected by hydrogen bonds. Animal experiments revealed that mNSS score and GSNOR levels in the hippocampus of rats in the model group were significantly higher than those in the sham operation group （P＜0.05）， while GSNO levels and survival rate were significantly lower than those in the sham operation group （P＜0.05）. The above indexes of rats were improved significantly in administration groups， the mNSS score in the XBJ group was significantly lower than that in the inhibitor group， the content changes of GSNOR and GSNO in the inhibitor group were more obvious than those in the XBJ group， and the various indicators in the XBJ+inhibitor group were significantly better than the XBJ group and the inhibitor group （P＜0.05）. GSNOR content was positively correlated with the mNSS score， and GSNO content was negatively correlated with the mNSS score （P＜0.05）. CONCLUSIONS XBJ can improve the neurological function of rats and enhance their survival rates after CA/CPR， the mechanism of which may be associated with the down-regulation of GSNOR and the up-regulation of GSNO.

BACKGROUND:There are differentially expressed genes in acute intracerebral hemorrhage,which are related to the occurrence and development of intracerebral hemorrhage. OBJECTIVE:To screen differentially expressed genes and key genes in brain tissue of a rat model with acute intracerebral hemorrhage,to validate them through qPCR,and to analyze the relationships between key genes and the neurological function and brain tissue water content after intracerebral hemorrhage. METHODS:Seventy-eight Sprague-Dawley rats were randomly divided into two groups:in intracerebral hemorrhage group,a rat model of acute intracerebral hemorrhage was made using collagenase injection at the right caudate nucleus;and in sham-operated group,rats were injected with equal amount of saline at the same site.RNA was extracted from rat brain tissues of both groups using the TRIzol method and transcriptome sequencing technology was used to identify differentially expressed genes in brain tissues of acute intracerebral hemorrhage,which were then verified by qPCR and analyzed for the relationships between the genes and neurological function and brain tissue water content after intracerebral hemorrhage.And the key genes were analyzed by GO and KEGG functional enrichment analysis in combination with bioinformatics. RESULTS AND CONCLUSION:Ten key genes were identified,including CXCL8,SERPINE1,TFPI2,CXCR4,GDA,KCNQ5,ERICH3,SCN3B,CACNA1E,and CCL20.The contents of GDA,KCNQ5,ERICH3,SCN3B,and CACNA1E in the intracerebral hemorrhage group were lower than those in the sham-operated group(P＜0.05).The contents of CXCL8,SERPINE1,TFPI2,CXCR4 and CCL20 in the intracerebral hemorrhage group were higher than those in the sham-operated group(P＜0.05).The contents of GDA,KCNQ5,ERICH3,SCN3B,and CACNA1E were positively correlated with brain tissue water content and neurologic deficit score(P＜0.05),while the contents of CXCL8,SERPINE1,TFPI2,CXCR4 and CCL20 were negatively correlated with brain tissue water content and neurologic deficit score(P＜0.05).GO analysis indicated that differentially expressed genes were mainly enriched in two biological processes(leukocyte chemotaxis and chemokine-mediated signaling pathways),two cell components(cation channel complexes and ion channel complexes),and two molecular functions(gated channel activity and ion channel activity).KEGG analysis indicated that differentially expressed genes were concentrated in tumor necrosis factor signaling pathway,glutamatergic synapses and GABAergic synapses.To conclude,the differentially expressed genes in intracerebral hemorrhage include CXCL8,SERPINE1,TFPI2,CXCR4,GDA,KCNQ5,ERICH3,SCN3B,CACNA1E,and CCL20,and these genes are related to brain tissue water content and neurological function after intracerebral hemorrhage.These genes are mainly enriched in cell components,binding functions,cellular protrusions,and other related biological functions.

Objective:To develop college students' proactive aggression questionnaire (CPAQ) and test its reliability and validity.Methods:From March 2023 to April 2024, a questionnaire survey was conducted among 1 552 college students(618 individuals in Sample 1, 783 individuals in Sample 2, 151 individuals in Sample 3 (retested after a 6-month interval), and 49 individuals in Sample 4 (randomly selected from Sample 3)).The reliability and validity of CPAQ were assessed using SPSS 24.0 and Mplus 8.3 software through item analysis, exploratory factor analysis, confirmatory factor analysis, internal consistency reliability, test-retest reliability, compatibility validity, discriminant validity, and empirical validity.Results:The results of the project analysis showed that the 33 items in the CPAQ were significantly correlated with the total score( r=0.25-0.78, P<0.05), and item scores between the high and low group were significantly different (all P<0.001). Exploratory factor analysis retained 28 items, which belonged to three dimensions of proactive aggression (instrumental motivation, moral inhibition, and moral disengagement). The results of confirmatory factor analysis showed that the three-dimensional model of the questionnaire was well fitted ( χ2/ df=3.25, CFI=0.96, TLI=0.95, RMSEA=0.05, SRMR=0.06). The Cronbach's α coefficients for the total score of CPAQ and its sub dimensions were 0.93, 0.95, 0.89 and 0.75, respectively(all P<0.05). The test-retest reliability was 0.64, 0.63, 0.67 and 0.60, respectively(all P<0.01). In the compatibility validity test, the instrumental motivation dimension score was positively correlated with the proactive aggression dimension score of reactive-proactive aggression questionnaire(RPQ)( r=0.50, P<0.05), while moral inhibition dimension was negatively correlated with empathy and guilt scores( r=-0.30, -0.39, P<0.05). The dimension of moral disengagement was positively correlated with the score of the moral disengagement scale( r=0.58, P<0.05). In the discriminant validity test, the correlation of CAPQ and RPQ reactive aggression dimension score was not significant( r=0.08, P=0.16). In the criterion related validity test, the correlation coefficients between the score of CAPQ and each calibration questionnaire and scale were 0.70-0.83. In the empirical validity test, there was a significant difference in the different CPAQ score groups for proactive aggressive behavior(high group: (1.16±0.18), low group: (1.04±0.08), t=2.60, P<0.05). Conclusion:CPAQ has good discrimination, reliability, and validity, which could be used as a tool to measure proactive aggressive behavior among college students.

Objective This study aims to investigate the current status of burnout among anesthesi-ology residents,and to explore its influencing factors and potential interventions.Methods A total of 2 651 practicing anesthesiology residents from 218 hospitals nationwide were included in this study.Demographic characteristics,occupational features,and psychological resilience scores(Connor-Davidson resilience scale)were collected using a questionnaire distributed electronically.The Maslach burnout inventory-human service survey(MBI-HSS)was used to assess burnout.A comparison between groups with and without occu-pational burnout was conducted.Multiple logistic regression analysis was used to identify risk factors for burnout among anesthesiology residents.Results Out of the expected 2 651 questionnaires,1 990 valid responses were received(response rate 77.7%).The prevalence of burnout among the residents was 53.4%(1 063/1 990).Compared with residents without occupational burnout,those with burnout had a signifi-cantly higher proportion of females,working in tertiary hospitals,unmarried individuals,frequency of en-countering challenging patients,participating in on-call duty,and research tasks,and had a significantly lon-ger weekly working hours(P＜0.05).Multivariate logistic regression analysis indicated that female(OR = 1.58,95%CI 1.28-1.97,P＜0.01),longer working hours(OR = 1.62,95%CI 1.45-1.81,P＜0.01),and higher frequency of encountering challenging patients(OR = 1.11,95%CI 1.11-1.40,P＜0.01)were risk factors for occupational burnout.High levels of psychological resilience was protective factor against burnout(OR = 0.86,95%CI 0.84-0.88,P＜0.01).Conclusion The occurrence of burnout among anesthesiology residents is high.It is crucial to focus on and design practical preventive measures to en-hance psychological resilience,ensuring healthy physical and mental development of the resident community.

Objective To explore the mechanism of Jianshen Lishui Decoction on nerve cell apoptosis in rats with cerebral hemorrhage.Methods The expression of miR-153 in cerebral hemorrhage was analyzed by miRNA microarray and RT-PCR,and the relationship between miR-153 and neuronal apoptosis in cerebral hemorrhage was observed,and predicted the target gene of miR-153;the binding of miR-153 to target genes was studied by dual-luciferase reporter gene Experiments,and to observe the effects of overexpression and inhibition of miR-153 on target genes.Subsequently,the relationship between target genes and neuronal apoptosis in cerebral hemorrhage was determined.Finally,the effect of Jianshen Lishui Decoction on miR-153 and the target gene,and finally explored the related mechanism of Jianshen Lishui Decoction on nerve cell apoptosis in rats with cerebral hemorrhage.Results Microarray chip and RT-PCR detection showed that miR-153 was lowly expressed in cerebral hemorrhage(P<0.05),and miR-153 was negatively correlated with neuronal apoptosis(R:-0.875,P=0.0002).The online databases TargetScan and miRDB showed that miR-153 has a binding region with TREM1,and the dual-luciferase reporter gene demonstrated a binding relationship between the two.When miR-153 was overexpressed,the expression of TREM1 was down-regulated,conversely,up-regulated when miR-153 was repressed,and TREM1 was positively correlated with nerve cell apoptosis(R:0.857,P<0.001).The expression of TREM1,the number of nerve cell apoptosis and the score of Neurological Deficit Scores in the Jianshen Lishui Decoction group were lower than those in the model group(P<0.05),and the expression of miR-153 was higher than that in the model group(P<0.05).The expression of TREM1,the number of nerve cell apoptosis and the score of Neurological Deficit Scores in the Jianshen Lishui Decoction +miR-153 inhibition group were higher than those in the Jianshen Lishui Decoction group(P<0.05).Conclusion Jianshen Lishui Decoction inhibits the apoptosis of nerve cells and protects the neurologicalfunctions in rats with cerebral hemorrhage by promoting miR-153 expression and inhibitingTREM1 expression.

  Objective  This study aimed to investigate Chinese anesthesiologists' comprehension of palliative care and their experiences with palliative sedation for patients in the end-stage of life.  Methods  From October to December 2021, a national cross-sectional survey was conducted among anesthesiologists in China distributed by the Chinese Society of Anesthesiology, Chinese Medical Association with convenient sampling. The survey questionnaire encompassed general information, professional experience, familiarity with palliative care, emotional responses to end-stage cases, experience with sedation for critically ill or end-stage patients, and preferences for sedation medication.  Results  A total of 2536 anesthesiologists from 29 provinces in China completed valid questionnaires. Among them, 572 anesthesiologists(22.6%, 572/2536) reported familiarity with palliative medicine. Male anesthesiologists, as well as those with prior experience in caring for critically ill or end-stage patients, involved in pain management and practicing in hospitals with established institutional palliative care teams, demonstrated greater familiarity with palliative care concepts(all P<0.05). Over 40% of respondents felt powerless, helpless, and indecisive when confronted with end-stage patients. Anesthesiologists knowledgeable about palliative care exhibited greater confidence in managing critically ill or end-stage patients(9.8% vs. 4.4%, P=0.001). Among the anesthesiologists surveyed, 734 had administered sedation to end-stage patients, with 151 of them(20.6%, 151/734) inappropriately relying solely on opioids for sedation.  Conclusions  The understanding of palliative care and palliative sedation medication choice among anesthesiologists in China is still very limited. The establishment of palliative care teams, provision of education and training in palliative care, and enhancement of familiarity with palliative principles may bolster anesthesiologists' confidence when encountering critically ill or end-stage patients and subsequently enhance the quality of care for patients in the terminal stages of life.
