OBJECTIVE To explore the mechanism of action of Qingre huatan huoxue decoction against atherosclerosis （AS）based on macrophage polarization. METHODS Using atorvastatin served as the positive control， the drug-containing serum of the Qingre huatan huoxue decoction was prepared to treat RAW264.7 macrophages. Macrophage viability， apoptosis rate， and the fluorescence intensities of CD86 and CD206 were measured， along with the levels of tumor necrosis factor-α （TNF-α） and interleukin-1β （IL-1β）. Apolipoprotei n E-deficient （ApoE －/－ ） mice （AS model mice） fed with a high-fat diet were randomly assigned to model group， atorvastatin group （2.6 mg/kg）， and low-， medium- and high-dose groups of Qingre huatan huoxue decoction （90， 180， 360 mg/kg）， respectively. C57BL/6J mice fed with a standard diet served as the normal control group， with 10 mice per group. The treatment group mice were administered the corresponding drugs intragastrically， once daily， for 8 consecutive weeks. Serum levels of TNF-α and IL-1β were measured in all groups. Lipid deposition in the aorta （assessed by the percentage of plaque in the entire aorta and aortic root） and morphological changes in the aortic root were observed. Expression levels of CD86 and CD206 in aortic tissue， as well as the protein expression levels of inducible nitric oxide synthase （iNOS）， arginase-1 （Arg-1）， AMP-activated protein kinase （AMPK）， phosphorylated AMPK （p-AMPK）， and peroxisome proliferator-activated receptor γ （PPAR-γ） in aortic tissues were all detected. RESULTS Cell experiment results showed that， at concentrations of 5-100 μg/mL， the drug-containing serum of the Qingre huatan huoxue decoction significantly increased RAW264.7 cell viability （ P ＜0.05）. The drug-containing serum of the Qingre huatan huoxue decoction at concentrations of 10， 50， and 100 μg/mL， along with atorvastatin， significantly reduced apoptosis rates， CD86 fluorescence intensity， and TNF-α and IL-1β levels in RAW264.7 cells， while markedly enhancing CD206 fluorescence intensity （ P ＜0.05）. Animal experiment results showed that， compared with the model group， all dosage groups of Qingre huatan huoxue decoction and the atorvastatin group showed significantly reduced/down-regulated levels of TNF-α and IL-1β in serum， along with decreased aortic total and root plaque percentages， CD86 expression， and iNOS protein expression. CD206 expression and Arg-1， p-AMPK/AMPK， PPAR-γ protein expression were significantly up-regulated （ P ＜0.05）. Pathological morphology of the aorta showed varying degrees of improvement. CONCLUSIONS The formula of Qingre huatan huoxue decoction exerts its anti-AS effects by regulating macrophage polarization， increasing the proportion of M2 macrophages， thereby effectively inhibiting AS plaque formation and reducing inflammatory responses.

Objective:To explore the application value of multiple indexes of high-frequency ultrasound in the diagnosis of shoulder stiffness, and to provide data support and theoretical basis for the diagnosis and treatment of shoulder stiffness.Methods:Clinical data of 261 patients with unilateral shoulder pain with limited mobility admitted to the Orthopedic Trauma, Hebei Medical University Third Hospital from January to December 2023 were retrospectively analyzed. With the results of shoulder arthroscopy as the gold standard, the patients were divided into 127 patients with shoulder stiffness (observation group) and 134 patients with non-shoulder stiffness and shoulder pain (control group). The fluid accumulation of long head of the biceps tendon (LHBT), echo of rotator interval (RI) and blood flow signal, thickness of coracohumeral ligament (CHL), thickness of subacromial-subdeltoid bursa (SASD), fluid accumulation and blood flow signal, fluid accumulation of posterior glenohumeral joint capsule (PJ), the inferior capsule thickness (ICT) and the thickness of inferior glenohumeral ligament (IGHL) were observed and measured in the two groups in addition, the CHL difference, ICT difference and IGHL difference between the affected side and the contralateral side were calculated, and the difference between the two groups of ultrasound indicators was compared and the multivariate logistic stepwise regression analysis was performed, and the receiver operating characteristic (ROC) curve was drawn to evaluate the diagnostic value of each indicator for shoulder stiffness.Results:RI hypoecho with increased blood flow signal, SASD thickening, SASD effusion, SASD blood flow signal detection rate, IGHL thickness, IGHL difference and ICT difference in observation group were significantly higher than those in the control group (all P<0.05). Multivariate logistic stepwise regression analysis showed that SASD thickening, SASD effusion and IGHL difference were independent predictors of shoulder stiffness (all P<0.05). The area under the curve of SASD thickening, SASD effusion and IGHL difference in the diagnosis of shoulder stiffness were 0.550, 0.540 and 0.636, respectively. The diagnostic sensitivity was 89.8%, 10.2% and 60.6%, and the specificity was 20.1%, 97.8% and 67.2%, respectively. The area under the curve was 0.676, the diagnostic sensitivity was 59.8%, and the specificity was 75.4%. Conclusions:High-frequency ultrasound is an effective imaging method to assist clinical diagnosis of shoulder stiffness. SASD thickening, SASD effusion and IGHL difference may be independent predictors of shoulder stiffness. The combined application of these three indicators has higher clinical application value and provides favorable ultrasound indicators for clinical differential diagnosis of shoulder stiffness.

Objective:To observe any clinical effect of supplementing ultrasound stimulation with balloon-guided injection of botulinum toxin into the upper esophageal sphincter in the treatment of cricopharyngeal achalasia.Methods:Forty patients with cricopharyngeal achalasia were randomly divided into an observation group and a control group, each of 20. Both groups were given routine swallowing rehabilitation training, while the observation group additionally had botulinum toxin injected into the upper esophageal sphincter guided by ultrasound and with the aid of balloon dilation. Before the experiment and after 2 weeks, both groups were evaluated videofluoroscopically and flexible endoscopic evaluation of swallowing was performed. Moreover, 2 weeks before the treatment and 2, 4 and 24 weeks afterward, everyone′s eating, leakage and aspiration, and oral and pharyngeal secretions were assessed using the functional oral intake scale (FOIS), the penetration-aspiration scale (PAS), the fiberoptic endoscopic dysphagia severity scale (FEDSS) and the Murray secretion scale (MSS).Results:After 2 weeks the average PAS, FEDSS and MSS scores of both groups had improved significantly, but the observation group′s averages[3(2, 5), 3(2, 5) and 2(1, 2)] were significantly better than those of the control group. 2, 4 and 24 weeks after the experiment the average FOIS scores of both groups also showed significant improvement, with the observation group′s average[3(2, 4), 4(2, 6) and 6(3, 7)] again significantly better than that of the control group.Conclusions:A botulinum toxin injection into the upper esophageal sphincter can effectively improve the swallowing of persons with cricopharyngeal achalasia with adequate safety and significant long-term benefits. Therefore, such treatment is worthy of clinical promotion and application.

AIM: To analyze and evaluate the use of pentoxifylline injection in a hospital, and explore effective supervision mode, so as to provide some reference for clinical rational drug use. METHODS: A total of 197 inpatients with pentoxifylline injection who were discharged from October 2021 to June 2022 were randomly selected from HIS system. Referring to drug-label and collecting evidence-based medical evidence to judge the rationality of use of pentoxifylline injection in the hospital. RESULTS: Among the 197 medical records extracted, 140 medical records were unreasonable, accounting for 71.07% of the total medical records. Among them, 111 cases (79.29%) were no indication for use, 13 cases (9.29%) were off-label, 2 cases (1.43%) were inappropriate for indications, 13 cases (9.29%) were inappropriate for usage and dosage, and 1 case (0.71%) was inappropriate for solvent. CONCLUSION: The irrational use of pentoxifylline injection in this hospital is serious. It is necessary to standardize its clinical application through the intervention of smart pharmacy management mode, improving system, strengthening medication education and other ways.

BACKGROUND: LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer. METHODS: We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels. RESULTS: On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]). CONCLUSION: LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile. TRIAL REGISTRATION ClinicalTrials.gov, NCT04563936.

Methods:Seventy SD rats were randomly divided into normal group, model group, high dose group, medium dose group, low dose group, western medicine group and combined group, with 10 rats in each group. Except the normal group, the other groups were sensitized with 1 ml ovalbumin and aluminum hydroxide mixture to establish the asthma rat model. On the 16th day of the experiment, the high, medium and low dose groups were given Yunpi-Xiefei-Huatan Decoction of 40, 20, 10 g/kg, respectively, the western medicine group was given carboxymethylstein tablets of 150 mg/kg, and the combined group was given Yunpi-Xiefei-Huatan Decoction of 20 g/kg and carboxymethylstein tablets of 150 mg/kg, once a day, for 4 weeks. The levels of tumor necrosis factor (TNF-α) and interleukin-13 (IL-13) in serum of rats were detected by Enzyme-linked Immunosorbent Assay (ELISA), the total number and classification of leukocytes in BALF were observed by Wright Giemsa staining, the pathological changes of lung tissue were observed by glycogen staining (PAS). The protein expression of epidermal growth factor receptor (EGFR) and MUC5AC (MUC5AC) were detected by Western blotting, and the mRNA expression of EGFR and MUC5AC was detected by Reverse Transcriptase Polymerase Chain Reaction (RT-PCR). Results:Compared with the model group, the level of IL-13 and TNF-α in the high, medium and low dose groups of traditional Chinese medicine, western medicine group and combined group was significantly decreased ( P<0.05). The levels of WBC, eosinophils and neutrophils in rat alveolar lavage fluid were significantly decreased ( P<0.05). The expression of EGFR (0.466 ± 0.023, 0.354 ± 0.047, 0.667 ± 0.066, 0.553 ± 0.065, 0.290 ± 0.033 vs. 0.782 ± 0.047) and MUC5AC (0.424 ± 0.022, 0.313 ± 0.033, 0.603 ± 0.051, 0.495 ± 0.041, 0.243 ± 0.024 vs. 0.806 ± 0.090) significantly decreased ( P<0.05), the m RNA expression of EGFR (2.302 ± 0.321, 2.549 ± 0.623, 3.084 ± 0.453, 2.585 ± 0.314, 1.810 ± 0.379 vs. 4.101 ± 0.567), MUC5AC (3.243 ± 0.742, 3.283 ± 1.064, 4.419 ± 0.572, 3.817 ± 0.637, 2.469 ± 0.424 vs. 5.840 ± 0.661) in the high, medium and low dose groups, western medicine group and combined group was significantly decreased ( P<0.05). Conclusion:Yunpi-Xiefei-Huatan Decoction ccould inhibit asthma, and its mechanism mightbe related to the EGFR/MUC5AC signaling pathway.

【Objective】 To evaluate the evolution and correlation of CT imaging signs and clinical features of non-severe coronavirus disease 2019 (COVID-19). 【Methods】 We retrospectively analyzed CT images and clinical features of 24 non-severe COVID-19 patients from the onset at a 5-day interval. We recorded CT image signs, clinical manifestations and laboratory results at each stage, and analyzed their dynamic changes and correlations. Categorical variables were presented by rates. The correlation of the total CT score and the total number of lesions with clinical manifestations was analyzed. P<0.05 indicated statistical significance. 【Results】 A total of 92 cases in 24 patients with COVID-19 were analyzed: 12 cases in 0-5 days, 21 in 5-10 days, 22 in 10-15 days, 20 in 15-20 days, and 17 in >20 days. The main CT signs of COVID-19 patients were subpleural and ground-glass opacity; the accompanying CT signs included paving stone sign, thickened blood vessels, fibrous cord shadow, air bronchial sign, leaflet center nodule, halo sign, reversed halo sign, bronchial wall thickening, and lung volume shrinking. On days 0-5, the number of lesions was the largest, acute symptoms were the most severe, the lymphocyte count and ratio were the lowest, and the concentration of high-sensitivity C-reactive protein (H-sCRP) was the highest. On days 5-10, the total CT score, the concentration of C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) were the highest, and the white blood cell count was the lowest. There were a positive correlation between the CT score and the number of lesions with temperature, ESR, CRP, H-sCRP, and negative correlation with WBC count. 【Conclusion】 CT imaging signs were similar to the change of the clinical features on days 0-10. The total CT score and the number of lesions had correlation with the clinical manifestations.

ObjectiveTo investigate the clinical features of patients with severe alcoholic hepatitis (AH) with different underlying liver diseases and the influencing factors for short-term prognosis. MethodsA retrospective analysis was performed for the clinical data of 170 patients with severe AH who were admitted to Tianjin Third Central Hospital from August 2004 to August 2018, and according to the underlying liver disease, they were divided into group A (27 patients without liver cirrhosis), group B (52 patients with compensated liver cirrhosis), and group C (91 patients with decompensated liver cirrhosis). Related scores were calculated, including Maddrey’s discriminant function (MDF) score, Chronic Liver Failure-Sequential Organ Failure Assessment (CLIF-SOFA) score, Model for End-Stage Liver Disease (MELD) score, age-bilirubin-international normalized ratio-creatinine (ABIC) score, and Glasgow alcoholic hepatitis score (GAHS). An analysis of variance or the Kruskal-Wallis H test was used for comparison of continuous data between multiple groups, and the chi-square test was used for comparison of categorical data between multiple groups. Univariate and multivariate Cox regression analyses were used to screen out the independent influencing factors for the short-term prognosis of patients with severe AH. The Kaplan-Meier method was used to plot survival curves, and the log-rank test was used for comparison of survival rate between groups. The receiver operating characteristic (ROC) curve was used to calculate the area under the ROC curve (AUC) and 95% confidence interval (CI), sensitivity, and specificity for each predictive model, and the DeLong method was used for comparison. ResultsThe 28-day survival rates of patients in groups A, B, and C were 88.9%, 80.8%, and 51.6%, respectively, with a significant difference between the three groups (χ2=1983, P＜0.001). The AUCs (95% CIs) of MELD score, MDF score, GAHS score, ABIC score, and CLIF-SOFA score were 0.584 (0.493-0.676), 0.696 (0.605-0.786), 0.644 (0.554-0.735), 0.745 (0.662-0.827), and 0.795 (0.726-0.863), respectively, in predicting 28-day mortality rate, and there were significant differences between CLIF-SOFA score and MDF, MELD, and GAHS scores (all P＜0.05); CLIF-SOFA score had a sensitivity of 79.0% and a specificity of 67.9% at the optimal cut-off value of 850 points in predicting 28-day mortality rate. Different underlying liver diseases (hazard ratio ［HR］=2.296, 95% CI: 1.356-3887, P=0.002) and hepatic encephalopathy (HR=1.911, 95% CI: 1.059-3.449, P=0.031) at disease onset were risk factors for 28-day prognosis. ConclusionPatients with severe AH with different underlying liver diseases have different clinical features and short-term prognoses. Different underlying liver diseases and hepatic encephalopathy at disease onset are closely associated with the 28-day prognosis of patients with severe AH. CLIF-SOFA score can predict the 28-day prognosis of patients with severe AH.
