BACKGROUND: The American Heart Association (AHA) introduced the concept of cardiovascular-kidney-metabolic (CKM) health and stage, reflecting the interaction among metabolism, chronic kidney disease (CKD), and the cardiovascular system. However, the association between CKM stage and the long-term risk of cardiovascular disease (CVD) has not been validated. This study aimed to evaluate the long-term CVD risk associated with CKM health metrics and CKM stage using data from a population-based cohort study. METHODS: In total, 5293 CVD-free participants were followed up to around 13 years in the Chinese Multi-provincial Cohort Study (CMCS). Considering the pathophysiologic progression of CKM health metrics abnormalities (comprising obesity, central adiposity, prediabetes, diabetes, hypertriglyceridemia, CKD, and metabolic syndrome), participants were divided into CKM stages 0, 1, and 2. The time-dependent Cox regression models were used to estimate the cardiovascular risk associated with CKM health metrics and stage. Additionally, broader CVD outcomes were examined, with a specific assessment of the impact of stage 3 in 2581 participants from the CMCS-Beijing subcohort. RESULTS: Among participants, 91.2% (4825/5293) had at least one abnormal CKM health metric, 8.8% (468/5293), 13.3% (704/5293), and 77.9% (4121/5293) were in CKM stages 0, 1, and 2, respectively; and 710 incident CVD cases occurred during a median follow-up time of 13.3 years (interquartile range: 12.1 to 13.6 years). Participants with each poor CKM health metric exhibited significantly higher CVD risk. Compared with stage 0, the hazard ratio (HR) (95% confidence interval [CI]) for CVD incidence was 1.31 (0.84-2.04) in stage 1 and 2.27 (1.57-3.28) in stage 2. Significant interactive impacts existed between CKM stage and age or sex, with higher CVD risk related to increased CKM stages in participants aged <60 years or females. CONCLUSION These findings highlight the contribution of CKM health metrics and CKM stage to the long-term risk of CVD, suggesting the importance of multi-component recognition and management of poor CKM health in CVD prevention.

OBJECTIVE: Varied acupoint selections represent a potential cause of the uncertainty surrounding the efficacy of acupuncture for knee osteoarthritis (OA). Skin temperature, a guiding factor for acupoint selection, may help to address this issue. This study explored thermal sensitization of acupoints used for the treatment of knee OA. METHODS: This cross-sectional case-control study enrolled cases aged 45-75 years with symptomatic knee OA and age- and gender-matched non-knee OA controls in a 1:1 ratio. All participants underwent infrared thermographic imaging. The primary outcome was the relative skin temperature of acupoint (STA), and the secondary outcome was the absolute STA of 11 acupoints. The Z test was used to compare the relative and absolute STAs between the groups. Principal component analysis was used to extract the common factors (CFs, acupoint cluster) in the STAs. A general linear model was used to identify factors affecting the STA in the knee OA cases. For the group comparisons of relative STA, P < 0.0045 (adjusted for 11 acupoints through Bonferroni correction) was considered to indicate statistical significance. For other analyses, P < 0.05 was used as the threshold for statistical significance. RESULTS: The analysis included 308 participants, consisting of 151 cases (mean age: [64.58 ± 6.67] years; male: 25.83%; mean body mass index: [25.70 ± 3.16] kg/m²) and 157 controls (mean age: [63.37 ± 5.96] years; male: 26.11%; mean body mass index: [24.47 ± 2.84] kg/m²). The relative STAs of ST34 (P = 0.0001), EX-LE2 (P < 0.0001), EX-LE5 (P = 0.0006), SP10 (P < 0.0001), BL40 (P = 0.0012) and GB39 (P = 0.0037) were higher in the knee OA group. No difference was found in the STAs of ST35, ST36, SP9, GB33 and GB34. Four CFs were identified for relative STA in both groups. The acupoints within each CF were consistent between the groups. The mean values of the relative STAs across each CF were higher in the knee OA group. In the knee OA cases, no factors were observed to affect the relative STA, while age and gender were found to affect the absolute STA. CONCLUSION Among patients with knee OA, thermal sensitization occurs in the acupoints of the lower extremity, exhibiting localized and regional thermal consistencies. The thermally sensitized acupoints that we identified in this study, ST34, SP10, EX-LE2, EX-LE5, GB39 and BL40, may be good choices for the acupuncture treatment of knee OA.

Objective:To investigate the current status of therapeutic relationships, organizational support, and compassion fatigue among psychiatric nurses, and to analyze the mechanism of action between these variables.Methods:This was a cross-sectional study. From August to September 2023, totally 310 psychiatric nurses were selected from three ClassⅢ Grade A psychiatric hospitals in Qingdao, Jinan, and Linyi by convenience sampling. Data were collected using a general information questionnaire, the Therapeutic Relationship Assessment Scale-Nurse (TRAS-N), the Perceived Organizational Support Scale (POSS), and the Chinese version of Compassion Fatigue short Scale (CCFS). SPSS 22.0 and the Process macro plugin were used for data analysis.Results:A total of 310 questionnaires were distributed, with 282 valid responses, yielding a response rate of 90.97%. The total score for TRAS-N among the 282 psychiatric nurses was (95.59±18.75), the total score for CCFS was 45.50 (24.75, 68.25), and the total score for POSS was (43.66±13.34). Therapeutic relationships were positively correlated with organizational support and negatively correlated with compassion fatigue, while organizational support was negatively correlated with compassion fatigue (all P< 0.01). Organizational support had a direct positive effect on therapeutic relationships (β=0.291, P<0.01) and also had an indirect effect through the mediating effect of compassion fatigue (β=0.212, P<0.01), with the mediation effect accounting for 42.15% of the total effect. Conclusions:Compassion fatigue partially mediates the relationship between organizational support and therapeutic relationships in psychiatric nurses. Nursing managers should enhance organizational support for psychiatric nurses to reduce their levels of compassion fatigue, thereby improving therapeutic relationships.

Objective: To explore the pathogenesis and risk factors of gallstone formation. Methods: The findings of hepatobiliary ultrasound and related data were collected from healthy subjects who underwent a physical examination at Xuanwu Hospital of Capital Medical University from January 2012 to December 2021. A total of 98 344 healthy subjects were included in the study,including 48 241 males and 50 103 females,with a ratio of 1∶1.03,aged (42.0±15.6)years(range:14 to 97 years). The gender,age,body mass index,waist circumference,systolic pressure,diastolic pressure,ALT,AST,total bilirubin,fasting blood glucose,triglyceride,total cholesterol,low-density lipoprotein,high-density lipoprotein were collected.Healthy subjects were required to sit for at least 10 minutes before blood pressure was measured.Rresults of fasting venous blood were collected after 8 to 12 hours on an empty stomach.According to the presence of gallstones by ultrasound results, healthy subjects were divided into study group and control group. Data were analyzed by rank-sum tests and χ² test, and risk factors for gallstone formation were explored by Logistic regression analysis. Results: The incidence of gallstones in this group was 5.42%(5 333/98 344). Among them,the incidence of gallstones in people aged 60 years and above was significantly higher than that in people under 60 years old(15.31%(2 348/15 334) vs. 3.60%(2 985/83 010), χ²=3 473.46,P<0.05).The healthy subjects were divided by age for every 10 years,and the results showed that the incidence of gallstones increased with age. The incidence of gallstones in females was 5.68%(2 844/50 103),greater than 5.16%(2 489/48 241) in males(χ²=11.81,P<0.05). Among them,1 478 cases underwent gallbladder surgical resection due to gallstones,and the operation rate was 27.71%. The operation rate reached the peak between 60 and <70 years old,and decreased after 70 years old. The results of the multivariate analysis showed that,female(OR=1.38, P<0.01),age(OR=1.58, P<0.01),body mass index≥24 kg/m²(OR=1.31, P<0.01),waist circumference≥85 cm(OR=1.24, P<0.01),fasting blood glucose>6.1 mmol/L(OR=1.18,P<0.01),total cholesterol≥5.18 mmol/L(OR=0.87, P=0.019),low-density lipoprotein≥3.37 mmol/L(OR=1.15,P=0.001) were the risk factors for gallstone formation;high-density lipoprotein≥1.55 mmol/L(OR=0.87, P<0.01) was a protective factor for gallstone formation. Conclusions: The incidence of gallstones increases with age in male and female. Gender,age,body mass index,waist circumferenc,fasting blood glucose,total cholesterol,LDL,and HDL are related factors with gallstone formation.

The Baimai Ointment with the effect of relaxing sinew and activating collaterals demonstrates a definite effect on Baimai disease with pain, spasm, stiffness and other symptoms, while the pharmacodynamic characteristics and mechanism of this agent remain unclear. In this study, a rat model of chronic compression of L4 dorsal root ganglion(CCD) was established by lumbar disc herniation, and the efficacy and mechanism of Baimai Ointment in the treatment of CCD were preliminarily explored by behavioral tests, side effect evaluation, network analysis, antagonist and molecular biology verification. The pharmacodynamic experiment indicated that Baimai Ointment significantly improved the pain thresholds(mechanical pain, thermal pain, and cold pain) and gait behavior of CCD model rats without causing tolerance or obvious toxic and side effects. Baimai Ointment inhibited the second-phase nociceptive response of mice in the formalin test, increased the hot plate threshold of normal mice, and down-regulated the expression of inflammatory cytokines in the spinal cord. Network analysis showed that Baimai Ointment had synergistic effect in the treatment of CCD and was related to descending inhibition/facilitation system and neuroinflammation. Furthermore, behavioral tests, Western blot, and immunofluorescence assay revealed that the pain-relieving effect of Baimai Ointment on CCD may be related to the regulation of the interaction between neuroactive ligand and receptors(neuroligands) such as CHRNA7, ADRA2A, and ADRB2, and the down-regulation of the expression of NOS2/pERK/PI3K, the core regulatory element of HIF-1 signaling pathway in spinal microglia. The findings preliminarily reveal the mechanism of relaxing sinew and activating collaterals of Baimai Ointment in the treatment of Baimai disease, providing a reference for the rational drug use and further research of this agent.

Objective:To establish a new strategy for rapid correction of the interference of chyle blood on hemoglobin (HGB) and related indexes by reticulocyte (RET) channel research parameters (HGB-O, MCHC-O) from automatic hematological analyzer.Methods:With the diagnostic experimental design, a total of 90 impatient samples were sequential picked from Fuwai Hospital, which had routine blood testing from June 1 to July 31, 2021. The selected samples were free of hemolysis, jaundice, chylo. The age of the patients was (49.2±5.7) years, with 47 males and 43 females. Three different contents(25, 50, 75 μl) of fat emulsion injection were used to replace plasma in equal amounts to prepare chyle blood samples with mild, medium and heavy degrees of average red blood cell hemoglobin concentration (MCHC). The research parameters (HGB-O, MCHC-O) obtained by the RET channel detection of the automatic blood analyzer were used as the corrected HGB and its related index values (RET method), and the original values (the detection values before adding fat emulsion) and the formula correction values were paired with t-test or Wilcoxon signed rank test, single factor analysis of variance or Kruskal-Wallis rank-sum test, Bland-Altman and correlation analysis to evaluate the correction effect of RET method.Results:There was no significant difference ( H=0.035, P=0.983; H=0.097, P=0.953; H=0.112, P=0.945) between the RET correction values of HGB (g/L) [104.0(83.8, 132.8), 109.0(87.78, 128.25), 104.0(87.8, 131.8)] and the original values [104.0(83.0, 133.0), 107.5(86.75, 129.25), 103.5(85.8, 131.3)] and the formula correction values [104.0(84.0, 133.8), 106.0(86.75, 131.25), 102.5(86.8, 131.3)] in the samples of chythemia with varying degrees of MCHC (g/L) elevation; meanwhile, the RET correction values [366.5(325.8, 341.5), 333.5(323.8, 340.0), 333.5(327.0, 341.25)] and the original values [336.0(324.8, 342.0), 333.0(323.5, 342.3), 332.0(326.75, 340.5)] and the formula correction values [333.5(323.5, 343.3), 331.0(321.0, 338.3), 329.5(325.25, 337.25)] were also not statistically significant ( H=0.049, P=0.976; H=3.149, P=0.207; H=0.883, P=0.643). The detection values of HGB and related indexes corrected by RET method were in good agreement with the original values [96.7% (29/30) of the points were within the 95% consistency limit], and the two were positively correlated (the correlation coefficients were all higher than 0.919, P<0.01). Conclusion:The RET method based on the research parameters of RET channel of automatic hematological analyzer can serve as a new strategy to correct the interference of chyle blood on the detection of HGB and related indexes.

Corydalis hendersonii(CH) is a Tibetan folk medicine with the functions of clearing heat, detoxifying, cooling blood, checking diarrhea, and lowering blood pressure. It is often used to treat high altitude polycythemia, vasculitis, peptic ulcer, and diarrhea. Nine compounds were separated from the ethanol extract of CH by silica gel, ODS, Sephadex LH-20 chromatography and semi-preparative HPLC. Their structures were identified as hendersine H(1),hendersine I(2), dehydrocheilanthifoline(3), protopine(4), izmirine(5), 6,7-methylenedioxy-1(2H)-isoquinolinone(6), icariside D_2(7), ethyl 4-(β-D-glucopyranosyloxy)-3-methoxybenzoate(8), 3-hydroxy-4-methoxybenzoic acid(9), respectively, by the spectroscopic data analysis and comparison with those in the literature. Among them, compounds 1 and 2 are new isoquinoline alkaloids, and compounds 7-9 are reported the first time for Corydalis. The hypoglycemic model of H9c2 cardiomyocytes and the inflammatory model of H9c2 cardiomyocytes induced by conditional supernatant were employed to determine the activities of the above compounds. The results showed that 20 μmol·L~(-1) compound 1 had a protective effect on H9c2 cardiomyocytes and 10 μmol·L~(-1) compounds 4 and 5 inhibited H9c2 cardiomyocyte inflammation induced by conditional supernatant.

OBJECTIVE: To explore the relationship between occurrence of acute graft-versus-host disease (aGVHD) and various immune cell composition in patients with acute myeloid leukemia (AML) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). METHODS: The clinical data of 104 patients with AML undergoing allo-HSCT in our hospital were retrospectively analyzed, and the hematopoietic reconstitution and occurrence of GVHD were analyzed. Flow cytometry was used to detect the proportion of various types of immune cells in the grafts, the number of graft composition in patients with different degrees of aGVHD was calculated and compared, and to analyze the correlation between the severity of aGVHD in AML patients after allo-HSCT and the immune cell components in the graft. RESULTS: There was no significant difference in the time of hematopoietic reconstitution between the high number group of total number of nucleated cells (TNC) and the low number group, while the time of neutrophil and platelet reconstruction in the high number of CD34 group was significantly faster than that in the low number of CD34 group (P＜0.05), and the total hospital stay also tends to be shorten. Compared with patients in 0-Ι aGVHD group, both HLA-matched and HLA-haploidentical transplantation, the infusion amounts of CD3⁺ cells, CD3⁺CD4⁺ cells, CD3⁺CD8⁺ cells, NK cells and CD14⁺ monocytes were higher in patients of Ⅱ-Ⅳ aGVHD group， but the difference was not statistically significant (P>0.05); In addition, in patients with HLA-haploidentical transplantation, the number of CD4⁺CD25⁺ cells in Ⅱ-Ⅳ aGVHD group was significantly lower than that in 0-Ι aGVHD group (P<0.05), and the same trend was also observed in HLA-matched transplanted patients, but the difference was not significant (P=0.078). CONCLUSION High number of CD34⁺ cells in the graft is beneficial to hematopoietic reconstitution in AML patients. To a certain degree, high number of CD3⁺ cells, CD3⁺CD4⁺ cells, CD3⁺CD8⁺ cells, NK cells and CD14⁺ cells tend to increase the occurrence of aGVHD, but high number of CD4⁺CD25⁺ regulatory T cells is beneficial to reduce the incidence of aGVHD in AML patients.

Objective: To study the incidence of bloodstream infections, pathogen distribution, and antibiotic resistance profile in patients with hematological malignancies. Methods: From January 2018 to December 2021, we retrospectively analyzed the clinical characteristics, pathogen distribution, and antibiotic resistance profiles of patients with malignant hematological diseases and bloodstream infections in the Department of Hematology, Nanfang Hospital, Southern Medical University. Results: A total of 582 incidences of bloodstream infections occurred in 22,717 inpatients. From 2018 to 2021, the incidence rates of bloodstream infections were 2.79%, 2.99%, 2.79%, and 2.02%, respectively. Five hundred ninety-nine types of bacteria were recovered from blood cultures, with 487 (81.3%) gram-negative bacteria, such as Klebsiella pneumonia, Escherichia coli, and Pseudomonas aeruginosa. Eighty-one (13.5%) were gram-positive bacteria, primarily Staphylococcus aureus, Staphylococcus epidermidis, and Enterococcus faecium, whereas the remaining 31 (5.2%) were fungi. Enterobacteriaceae resistance to carbapenems, piperacillin/tazobactam, cefoperazone sodium/sulbactam, and tigecycline were 11.0%, 15.3%, 15.4%, and 3.3%, with a descending trend year on year. Non-fermenters tolerated piperacillin/tazobactam, cefoperazone sodium/sulbactam, and quinolones at 29.6%, 13.3%, and 21.7%, respectively. However, only two gram-positive bacteria isolates were shown to be resistant to glycopeptide antibiotics. Conclusions: Bloodstream pathogens in hematological malignancies were broadly dispersed, most of which were gram-negative bacteria. Antibiotic resistance rates vary greatly between species. Our research serves as a valuable resource for the selection of empirical antibiotics.
