Objective:To investigate the efficacy of Zhibitai capsules combined with low-dose atorvastatin in the treatment of cervical arteriosclerosis and its effects on high-sensitivity C-reactive protein and regulatory T cells in the peripheral blood. Methods:A total of 104 patients with carotid arteriosclerosis admitted to Fenyang Hospital from January 2021 to April 2022 were retrospectively included in this study. They were divided into a control group ( n = 52) and an observation group ( n = 52) according to different treatment methods. The control group was orally given atorvastatin calcium tablets 20 mg once a day. The observation group was orally given atorvastatin calcium tablets 10 mg once a day, and Zhibitai capsules 0.24 g, one capsule in the morning and one capsule in the evening. After 8 weeks of treatment, changes in total cholesterol, triacylglycerol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, high-sensitivity C-reactive protein, and regulatory T cell proportion in the peripheral blood were evaluated. Results:After treatment, high-density lipoprotein cholesterol level and regulatory T cell proportion in the observation group were (1.53 ± 0.29) mmol/L and (5.52 ± 1.38)%, respectively, which were significantly higher than (1.19 ± 0.21) mmol/L and (4.48 ± 0.86)% respectively in the control group ( t = 6.84, 4.61, both P < 0.05). Total cholesterol, triacylglycerol, low-density lipoprotein cholesterol, and high-sensitivity C-reactive protein levels in the observation group were (2.88 ± 0.27) mmol/L, (1.21 ± 0.15) mmol/L, (2.01 ± 0.19) mmol/L, (2.58 ± 0.43) mg/L, respectively, which were significantly lower than (3.68 ± 0.41) mmol/L, (1.33 ± 0.19) mmol/L, (2.69 ± 0.31) mmol/L, (3.70 ± 0.25) mg/L, respectively in the control group ( t = 11.75, 3.57, 12.31, 17.23, all P < 0.05). There was no significant difference in carotid plaque size pre-treatment between the two groups, but the plaque size decreased after treatment compared with before treatment. The efficacy of Zhibitai capsules combined with low-dose atorvastatin in the treatment of cervical arteriosclerosis in the observation group was superior to that in the control group ( P < 0.05). Conclusion:Oral administration of Zhibitai capsules combined with low-dose atorvastatin for the treatment of cervical arteriosclerosis is safe and has few adverse reactions. The combined therapy can decrease serum high-sensitivity C-reactive protein levels, increase the proportion of regulatory T cells in the peripheral blood, help stabilize plaques, and reduce plaque size.

Objective:To provide data reference for using Chinese rhesus macaques as research model by studying the immunophenotype and function of peripheral blood lymphocytes in Chinese rhesus macaques.Methods:By optimizing antibody clones and fluorescent colors, the lymphocyte subset assay and T cell function assay panels were determined. Then the panels were used to analyze the proportion of T, B, NK and other cell subsets in peripheral blood mononuclear cells (PBMCs) in 15 healthy Chinese rhesus monkeys, and the ability of T cells to secrete cytokines after non-specific stimulation.Results:Two multi-color flow cytometry analytic panels were established. Panel 1 could simultaneously detect a variety of lymphocyte subsets, including cytotoxic T lymphocytes, follicular helper T cells, regulatory T cells, B cells and NK cells. Panel 2 could detect the functions of multiple T cell subsets and the expression of immune checkpoint moleculars. The mean percentages of T, B, NK, Tfh, Treg, CD16 + NK and CD56 + NK cells in PBMCs of the Chinese rhesus macaques were (75.32±7.73)%, (13.22±7.50)%, (0.88±0.48)%, (0.73±0.27)%, (0.75±0.43)%, (47.87±22.35)% and (10.69±12.41)%. After non-specific stimulation, the proportion of CD4 + T cells secreting IL-2 and TNF-α was higher than that of CD8 + T cells, and the proportion of CD8 + T cells secreting CD107a and IFN-γ was higher than that of CD4 + T cells, while the proportion of CD4 + and CD8 + T cells secreting IL-17A was low. Conclusions:This study established a multi-color flow detection scheme that could simultaneously detect multiple cellular surface molecules and cytokines at the single cell level and could accurately and comprehensively analyze the immune cell subsets, functions and the immune checkpoint molecules in peripheral blood of Chinese rhesus macaques, providing a new experimental method and basic data for the development of vaccines and drugs against infectious diseases.

Jinyinqingre Oral Liquid alleviates LPS-induced acute lung injury by inhibiting the NF-κB/NLRP3/GSDMD pathway / 中国天然药物

Acute lung injury (ALI) is a prevalent and severe clinical condition characterized by inflammatory damage to the lung endothelial and epithelial barriers, resulting in high incidence and mortality rates. Currently, there is a lack of safe and effective drugs for the treatment of ALI. In a previous clinical study, we observed that Jinyinqingre oral liquid (JYQR), a Traditional Chinese Medicine formulation prepared by the Taihe Hospital, Affiliated Hospital of Hubei University of Medicine, exhibited notable efficacy in treating inflammation-related hepatitis and cholecystitis in clinical settings. However, the potential role of JYQR in ALI/acute respiratory distress syndrome (ARDS) and its anti-inflammatory mechanism remains unexplored. Thus, the present study aimed to investigate the therapeutic effects and underlying molecular mechanisms of JYQR in ALI using a mouse model of lipopolysaccharide (LPS)-induced ALI and an in vitro RAW264.7 cell model. JYQR yielded substantial improvements in LPS-induced histological alterations in lung tissues. Additionally, JYQR administration led to a noteworthy reduction in total protein levels within the BALF, a decrease in MPAP, and attenuation of pleural thickness. These findings collectively highlight the remarkable efficacy of JYQR in mitigating the deleterious effects of LPS-induced ALI. Mechanistic investigations revealed that JYQR pretreatment significantly inhibited NF-κB activation and downregulated the expressions of the downstream proteins, namely NLRP3 and GSDMD, as well as proinflammatory cytokine levels in mice and RAW2647 cells. Consequently, JYQR alleviated LPS-induced ALI by inhibiting the NF-κB/NLRP3/GSDMD pathway. JYQR exerts a protective effect against LPS-induced ALI in mice, and its mechanism of action involves the downregulation of the NF-κB/NLRP3/GSDMD inflammatory pathway.

Manifestations of liver injury in 333 hospitalized patients with coronavirus disease 2019 / 中华消化杂志

Objective:To investigate the manifestations of liver injury in hospitalized patients with coronavirus disease 2019 (COVID-19), to investigate the prognosis indicators of the disease, and to provide the reference for clinical diagnosis and treatment.Methods:From January 10 to February 14, 2020, at Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, the data of 333 hospitalized patients with COVID-19 were collected. The changes of alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBil), direct bilirubin (DBil), indirect bilirubin (IBil) and albumin of the first liver function test after admission and the reexaminations of liver function test during hospitalization period in patients with liver injury were retrospectively analyzed. Student t test and Chi-square test were used for statistical analysis. Results:Liver injury occurred in 39.6% (132/333) of COVID-19 patients. There was no statistically significant difference in the rate of liver injury between patients in intensive care unit (ICU) and in general ward (45.6%, 26/57 vs. 38.4%, 106/276; χ2=1.026, P>0.05). 67.4% (89/132) of COVID-19 patients with liver injury presented with increased ALT or AST level on admission. During hospitalization, the level of ALT was higher than that of the first examination after admission ((60.28±50.44) U/L vs. (42.25±32.21) U/L), and the difference was statistically significant ( t=-3.230, P<0.05). The levels of ALT and AST of 71.2% (94/132) patients were both <80 U/L, which indicated that most of the patients showed mild liver injury. The patients with elevated level of TBil, DBil and IBil accounted for 3.9% (13/333), 5.4% (18/333) and 2.4% (8/333) of the COVID-19 patients, respectively. The albumin level of COVID-19 patients with liver injury during hospitalization was lower than that of the first examination after admission ((31.8±5.1) g/L vs. (33.7±5.4) g/L), and the difference was statistically significant ( t=2.712, P<0.05). The albumin levels at first examination on admission and reexamination during hospitalization of patients in ICU were both significantly lower than those of patients in general ward ((29.3±3.7) g/L vs. (34.8±5.1) g/L and (27.6±2.8) g/L vs. (32.9±5.1) g/L), and the differences were statistically significant ( t=4.928 and 4.783, both P<0.05). Conclusions:The incidence of liver injury in COVID-19 patients is high. A slight increase in aminotransferase levels is particularly common. Bilirubin abnormality is relatively rare and mild. The level of albumin may be one of the indicators for the severity and prognosis of COVID-19.

Therapeutic endoscopy in combination with quadruple therapy in treating bleeding caused by gastric ulcer

Objective: To analyze the efficacy of therapeutic endoscopy in combination with quadruple therapy in treating bleeding caused by gastric ulcer and investigate the factors inducing rebleeding

Methods: Two hundred and twelve patients with bleeding caused by gastric ulcer who were admitted to Binzhou People's Hospital, Shandong, China between April 2015 and April 2016 were selected as research subjects. The patients were randomly divided into a control group and an experimental group. Patients in the control group were treated by quadruple therapy, while patients in the observation group received therapeutic endoscopy treatment in addition to the same treatment as the control group. The treatment efficacy, adverse reaction, H pylori [Hp] clearance rate and rebleeding were compared between the two groups

Results: The effective rate of the observation group was 98.1%, which was significantly higher than that of the control group [80.2%], and the difference had statistical significance [P<0.05]. The incidence of adverse reactions in the observation group was lower than that in the control group. The Hp clearance rate of the observation group was higher than that of the control group, and the difference had statistical significance [P<0.05]. The multi-factor analysis on rebleeding suggested that whether therapeutic endoscopy was performed or not, hemoglobin level and presence of peptic ulcer stage A1 were independent risk factors

Conclusion: Endoscopic treatment in combination with quadruple therapy is better in the treatment of bleeding caused by gastric ulcer as compared to medical treatment alone. Patients with high-risk factors such as low content of hemoglobin and ulcer at stage A1 should be monitored more carefully to prevent the occurrence of rebleeding
