Based on the theories of "pathogenesis caused by constraint emotions" and "visceral orifices"， it is believed that the pathogenesis of tinnitus caused by constraint syndrome follows the evolution pattern of "qi constraint （liver qi constraint） → fire disturbance （liver constraint transforming into fire） → deficiency impairment （liver constraint with spleen deficiency） → blood stasis （liver constraint leading to blood stasis）". The treatment is guided by the principle of integrated internal and external therapy with harmonization of both body and mind. Internally， the treatment focuses on rectifying zang-fu imbalances， primarily using the Xiaoyao Powder （逍遥散）， with modifications based on syndrome differentiation. External therapies aim to unblock the meridians and orifices， commonly using auricular acupressure and Chinese herbal hot compresses. Additionally， traditional Chinese five-tone music therapy is applied to regulate emotional and mental disturbances. By integrating these three approaches， a comprehensive treatment strategy is formed that harmonizes both body and mind for managing tinnitus associated with constraint syndrome.

Objective:To explore the feasibility and effectiveness of full free-breathing cardiac magnetic resonance (CMR) in clinical practice.Methods:The study prospectively included patients who underwent full free-breathing CMR and traditional breath-holding cine imaging between June 1 and June 30, 2024. An analysis and comparison were conducted on the image acquisition time, image quality, and left ventricular function parameters under two scanning methods, including left ventricular ejection fraction (LVEF), left ventricular cardiac output (LVCO),left ventricular end diastolic volume (LVEDV), left ventricular end diastolic volume index (LVEDVI), left ventricular end systolic volume (LVESV), left ventricular end systolic volume index (LVESVI), left ventricular stroke volume (LVSV), and left ventricular mass (LVM). In addition, the study conducted both quantitative and qualitative analyses of other sequences in full free-breathing CMR, including T 1 mapping, T 2 mapping, flow imaging, and late gadolinium enhancement (LGE). Group comparisons were performed using the Wilcoxon signed-rank test or paired t-test. Consistency assessments included Bland-Altman analysis, intraclass correlation coefficient ( ICC), and linear regression analysis. Results:Totally, 150 patients were recruited into the study. The average acquisition time of full free-breathing CMR was (22.1±3.1) min, with an average short axis cine sequence examination time of (2.7±0.4) min; The average acquisition time of short axis images in a breath-holding state was (4.9±1.4) min, which was significantly longer than the cine scan in the free-breathing state ( P0.001). The cine and LGE images quality scores obtained from full free-breathing CMR were 4 (4, 4) points and 5 (4, 5) points, respectively, while the cine image quality score obtained in a breath-holding state was 5 (4, 5) points. Compared with traditional breath-hold CMR, free-breathing CMR measurements showed slightly higher LVESV, and LVESVI, while LVEDV, LVEDVI, LVSV, LVCO, LVEF, and LVM were slightly lower, except for LVSV and LVCO, which showed no statistically significant difference, the differences in other cardiac function parameters were statistically significant ( P0.05). However, the two methods demonstrated good consistency( ICC0.947) and correlation (0.808 r0.993, P0.001). The Bland-Altman analysis showed that the bias for all cardiac function parameters was within 8.0%. The Native T 1 and T 2 values for free-breathing CMR were (1 277.5±57.0) ms and 40.1 (38.5, 41.4) ms, respectively, and the results of flow imaging and echocardiography were basically consistent. Conclusions:Free-breathing CMR is feasible and effective in clinical practice, showing a high level of consistency with left ventricular functional parameters obtained from traditional breath-hold scanning. It significantly shortens examination time and holds great clinical value for the promotion and widespread use of CMR.

OBJECTIVE To investigate the effects of clopidogrel on the pharmacokinetics and pharmacodynamics of ciprofol in rats.METHODS Eighteen male SD rats were randomly divided into control group,clopidogrel normal-dose group and clopidogrel high-dose group,with 6 rats in each group.Among them,rats in the normal-dose group and high-dose group were given 7.5 mg/kg and 15 mg/kg clopidogrel by gavage,respectively,and rats in the control group were given the same volume of 0.5％sodium carboxymethyl cellulose solution,once a day,for 14 consecutive days.Afterward,2.4 mg/kg ciprofol was injected by tailvein and blood samples were collected from the inner canthus of the eye at 2,4,8,12,16,20,30,45 and 60 min after the end of the administration.During this period,the duration of the loss of righting reflex(LORR)in rats was counted.After the proteins were precipitated by acetonitrile,the rat plasma sample was analyzed by LC-MS/MS using deuterated ciprofol as the internal standard,Symmetry C18 as the chromatographic column,and acetonitrile-0.01％ammonia solution containing 5 mmol/L ammonium acetate(gradient elution)as the mobile phase to detect the concentration of ciprofol in the plasma.The pharmacokinetic parameters in rats were calculated by using DAS 2.0 software.RESULTS Compared with control group,area under the drug concentration-time curve and mean residence time of ciprofol increased or prolonged significantly,while plasma clearance decreased significantly in clopidogrel normal-dose and high-dose groups;the duration of LORR in rats was prolonged by 19.5％and 23.9％,with statistical difference(P＜0.05).However,there was no statistically significant difference in the pharmacokinetic parameters or LORR duration of ciprofol between the different dose groups of clopidogrel(P＞0.05).CONCLUSIONS Clopidogrel could inhibit the metabolism of ciprofol in rats and prolong the duration of LORR.

Objective:To explore the predictive value of the neutrophil-to-lymphocyte ratio (NLR) and soluble triggering receptor expressed on myeloid cell-1 (sTREM-1) for the risk of severe community-acquired pneumonia (CAP) in elderly patients.Methods:A total of 109 elderly CAP patients admitted to Shanghai Sixth People′s Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from November 2023 to May 2024 were included. The patients were classified into severe group and non-severe group according to the severity of the disease. Inflammatory markers including NLR, sTREM-1, platelet-to-lymphocyte ratio (PLR), procalcitonin (PCT), C-reactive protein (CRP), and interleukin-6 (IL-6) were compared between severe group and non-severe group. Levels of NLR, sTREM-1, and PLR on days one, four and seven after admission in 27 elderly patients with severe CAP were dynamically monitored. Statistical analyses were performed using two independent sample t-test and Mann-Whitney U test. The predictive factors for severe CAP in elderly patients were analyzed by multivariate logistic regression analysis, and receiver operating characteristic (ROC) curve was used to evaluate the efficacy of each indicator for predicting severe CAP in elderly patients. Results:There were 36 cases in severe group, and 73 cases in non-severe group. The levels of NLR, sTREM-1, PLR, PCT, CRP and IL-6 were significantly higher in the severe group than those in the non-severe group ( Z=-5.77, -3.48, -2.84, -3.94, -3.36 and -3.25, respectively; all P<0.01). Multivariate logistic regression analysis revealed that NLR and sTREM-1 were independent predictive factors for severe CAP in elderly patients (odds ratio ( OR) =1.112, 95% confidence interval ( CI) 1.000 to 1.235, P=0.049; OR=1.006, 95% CI 1.000 to 1.012, P=0.034). The ROC curve showed that the optimal cut-off value was 5.679 for NLR, and the area under the curve (AUC) was 0.841, with the sensitivity and specificity of 0.833 and 0.753, respectively. The optimal cut-off value of sTREM-1 was 151.275 ng/L (AUC was 0.731), with the sensitivity and specificity of 0.639 and 0.639, respectively. The AUC of the combined detection of NLR and sTREM-1 was 0.839, with the sensitivity and specificity of 0.944 and 0.630, respectively. The levels of sTREM-1 ((121.84±75.04) ng/L vs (179.06±85.44) ng/L), NLR (6.74±4.40 vs 11.87±7.78), and PLR (210.07±129.93 vs 294.91±187.61) on the 7th day of admission in 27 elderly patients with severe CAP were significantly lower than those on the 1st day ( t=-3.396, -3.492 and -3.396, respectively, P=0.005, 0.004 and 0.005, respectively). Conclusions:NLR and sTREM-1 have certain predictive value for the risk of severe CAP in elderly patients.

Objective:This study aims to explore the expression characteristics of mitochondrial function-related genes in patients with manic episodes of bipolar disorder and the correlation between differentially expressed genes and clinical metabolic indicators.Methods:Twenty patients with manic episodes of bipolar disorder (patient group) and 20 healthy controls (control group) were included. Quantitative real-time PCR was used to detect mitochondrial quality control and oxidative phosphorylation-related gene expression in peripheral blood leukocytes, and several metabolic indicators were collected. Mann-Whitney test or independent sample t-test was used for comparison between groups. Spearman correlation test was used to analyze the correlation between gene expression and metabolic indicators. Results:Mitochondria function-related genes, including NRF2, P62, MFN1, MFN2, YME1L, MFF, MTATP8, and AIF, were significantly lower in patients with bipolar disorder than in healthy controls ( P<0.05, U=86, 90, 97, 93, 106, 89, 93, 105, FDR=0.038). The expression level of MTATP8 was negatively correlated with BMI, total cholesterol, and globulin level in the patient group ( r=-0.49, -0.58, -0.46, P=0.028, 0.009, 0.050). The expression level of MFF was significantly negatively correlated with waist circumference in healthy controls ( r=-0.53, P=0.020) and with globulin level in the patient group ( r=-0.48, P=0.040). The expression level of AIF was significantly and positively correlated with high-density lipoprotein cholesterol in healthy controls ( r=0.53, P=0.036). Conclusion:The expression of several genes involved in mitochondrial quality control and oxidative phosphorylation processes was significantly downregulated, and differentially expressed genes were significantly associated with metabolic index, suggesting that mitochondrial dysfunction may be related to the high risk of metabolic disease in patients with manic episodes of bipolar disorder.

Objective:To investigate the clinical pathological and epidemiological characteristics of primary esophageal malignant melanoma (PMME).Methods:The clinical pathology data of 180 PMME patients in the esophageal cancer database of the key laboratory of esophageal cancer research in Henan Province from 1973 to 2016 were collected, of which 136 were male, aged (58.5±9.0) years, 44 were female, aged (56.7±12.2) years. Kaplan-Meier and Log rank test were used for survival analysis, Cox regression scale model was used for risk factor analysis.Results:The incidence of PMME is 0.036% (180/500, 000), mostly were male (about 3∶1 for men: female). The common sites of PMME were the lower part of the esophagus (48.9%, 85/174), followed by the middle section of the esophagus (46.0%, 80/174) and the upper part of the esophagus (5.2%, 9/174). No black particles were seen in the PMME cells of 3 patients under microscope, and strong positive expressions of Melan-A and HMB453 were observed in these 3 patients by immunohistochemical results. Of the 129 patients who had a routine preoperative esophageal biopsy, 69 were undiagnosed with PMME (53.5%). The medium survival time of the whole group was 7.9 months, and the survival rates of 1, 2, 3, 5 years were 25.0%, 7.9%, 6.6% and 1.3%, respectively. The univariate analysis showed that N, M, TNM phase and radiotherapy were related to the overall survival of patients ( P<0.05). Multivariate analysis showed that TNM phase and radiotherapy were the independent risk factors for overall survival of patients ( P<0.05). Conclusions:PMME is more common in men, the common site of the disease is the lower part of the esophagus. The preoperatively missed diagnosis rate of Chinese PMME is high. TNM phase and radiotherapy are the independent risk factors for overall survival of patients.
