Effect of Dapagliflozin on Ventricular Remodeling and Prognosis in Patients with Coronary Atherosclerotic Heart Disease Undergoing Percutaneous Coronary Intervention.

Objective: Acute coronary syndrome (ACS) is a common cardiovascular complication in patients with type 2 diabetes mellitus (T2DM) and significantly increases the risk of disability and death in T2DM patients. Dapagliflozin inhibits blood glucose reabsorption, improves insulin resistance, and reduces the occurrence of long-term adverse cardiovascular events, indicating the importance of Dapagliflozin as a drug for type 2 diabetes patients and its close relationship with coronary atherosclerotic heart disease. At present, there are few studies on the effects of Dapagliflozin intervention on ventricular remodeling and myocardial microperfusion in patients with ACS combined with T2DM after PCI. Methods: Between January 2019 and August 2023, a total of 35 patients diagnosed with Coronary atherosclerotic heart disease and T2DM were chosen as the observation group using a multi-stage cluster sampling method. Concurrently, 35 patients with similar age, height, weight, and healthy physical examination results were selected as the control group during the same time frame. We collected demographic data, symptoms and underlying diseases of the two groups Before enrollment and 6 months after discharge and compared the data between the two groups. Subsequently, multivariate logistic regression analysis was employed to identify indicators with statistically significant differences and to summarize the potential risk factors that could impact ventricular remodeling in patients with Coronary atherosclerotic heart disease and T2DM. Results: There was significant difference in LDL-C between the two groups, and the difference was statistically significant (P < .05). After treatment, the levels of hs-CRP, FBG, HbAlc and IL-6 in both groups were significantly decreased, and the decrease was more obvious in the observation group, with statistical significance (P < .05). These results indicated that Dapagliflozin intervention could significantly inhibit postoperative inflammation in patients with ACS combined with T2DM after PCI. LVMI of Observation group patients was significantly higher than Comparison group, LVEDD and ESVI of Observation group patients were significantly lower than Comparison group. The difference was statistically significant (P < .05). These results indicated that Dapagliflozin intervention could significantly inhibit the improvement of blood glucose index, ventricular remodeling and myocardial microperfusion in patients with ACS combined with T2DM after PCI. After treatment, TIMI Flow Count Frame Count (CTFC) level and Myocardial Perfusion (TMPG) level in the observation group were significantly lower than those in the comparison group, and the difference was statistically significant (P < .05). These results indicated that Dapagliflozin intervention could significantly inhibit ventricular remodeling and improve myocardial microperfusion in patients with ACS combined with T2DM after PCI. Conclusion: Dapagliflozin intervention can significantly inhibit inflammatory indexes in patients with Coronary atherosclerotic heart disease combined with T2DM after PCI, promote the improvement of blood glucose indexes, ventricular remodeling and myocardial microperfusion, and reduce the risk of occurrence.

Effects and mechanism of Chinese medicine Jiawei Yupingfeng in a mouse model of allergic rhinitis / 中西医结合学报

OBJECTIVE@#Chinese medicine has the potential to modulate allergic rhinitis (AR). There have been studies investigating the treatment efficacy of Yupingfeng San, alone or in combination with other ingredients, in AR, though few have studied the potential mechanisms of these drugs. In the present study, we measured the effects of Jiawei Yupingfeng (JWYPF), a traditional Chinese medicine formula, on mice with ovalbumin-induced AR and explored its underlying mechanism of action.@*METHODS@#Forty BALB/c mice were randomly divided into normal control, allergy control and two treatment groups of ten mice each. In the normal control group, mice were sensitized and challenged with saline. The mice in the allergy control and treatment groups were sensitized and challenged with ovalbumin and aluminum hydroxide gel. The treatments of JWYPF and Nasonex were administered intranasally in the AR mice for one week. Several signs of allergic inflammation, such as nasal eosinophils and inflammatory cytokines, were measured to determine the underlying mechanisms.@*RESULTS@#Mice in the JWYPF and Nasonex groups had significantly lower AR symptom scores than those in the allergy control group (the mean differences between JWYPF and the allergy control, and Nasonex and the allergy control were -2.00 ± 0.35 and -2.40 ± 0.32). After treatment with JWYPF and Nasonex, the levels of ovalbumin-specific IgE and histamine were significantly reduced, as were the levels of interlukin-4 and transforming growth factor-β, while interferon-γ levels were increased (all P < 0.0001, vs. allergy control). These two treatments also significantly inhibited eosinophil and mast cell infiltration into the nasal cavity but were not statistically different from one-another.@*CONCLUSION@#JWYPF has a potential therapeutic effect on AR via adjusting the rebalance of T helper 1 and T helper 2.

Meta-Analysis Based on Clinical RCTs: The Effect of Molecular Epimerism on the Safety of Glycyrrhizic Acid.

OBJECTIVE: To carry out the meta-analysis on the clinical safety of glycyrrhizic acid and the influencing factors between 18α-glycyrrhizinate (18α-GL) and 18ß-glycyrrhizinate (18ß-GL). METHODS: Magnesium isoglycyrrhizinate injection was used as the representative preparation of 18α-GL, and compound glycyrrhizin injection was used as the representative preparation of 18ß-GL. The clinical control trial of magnesium isoglycyrrhizinate injection and compound glycyrrhizin injection was searched in a computer, which was published from January 2006 to December 2019 on the databases such as PubMed, China National Knowledge Infrastructure (CNKI), China Science and Technology Journal Database (CSTJ), and Wanfang Medical Network (Wanfang Data). The data associated with adverse drug reactions (ADRs) were extracted. RevMan5.3 was used for statistical analysis. RESULTS: Finally, 24 studies were included, and 2757 patients were involved, of which the experimental group was mainly treated with magnesium isoglycyrrhizinate, while the control group was mainly treated with compound glycyrrhizin. The results showed that the occurrence of ADRs was significantly lower in the experimental group than that in the control group, and the difference between two groups was statistically significant (RR = 0.26, 95% CI = (0.18, 0.38), P < 0.00001). There was no heterogeneity among the studies (I 2 = 0%, P=1.00). CONCLUSION: Compared with 18ß-GL, 18α-GL had a lower incidence of adverse reactions and better clinical safety.

Dosimetry of the brain and hypothalamus predicting acute lymphopenia and the survival of glioma patients with postoperative radiotherapy.

BACKGROUND: The aim of this study was to investigate dosimetric factors for predicting acute lymphopenia and the survival of glioma patients with postoperative intensity-modulated radiotherapy (IMRT). METHODS: A total of 148 glioma patients were reviewed. Acute lymphopenia was defined as a peripheral lymphocyte count (PLC) lower than 1.0 × 109 /L during radiotherapy with a normal level at pretreatment. PLCs with the corresponding dates and dose volume histogram parameters were collected. Univariate and multivariate Cox regression analyses were constructed to assess the significance of risk factors associated with lymphopenia and overall survival (OS). RESULTS: Sixty-nine (46.6%) patients developed lymphopenia during radiotherapy. Multivariate analyses revealed that the risk increased with the maximal dose of the hypothalamus (HT Dmax) ≥56 Gy (58.9% vs 28.5%, P = 0.002), minimal dose of the whole brain (WB Dmin) ≥2 Gy (54.3% vs 33.9%, P = 0.006), or mean dose of the WB (WB Dmean) ≥34 Gy (56.0% vs 37.0%, P = 0.022). Patients with older age, high-grade glioma, development of lymphopenia, high HT Dmax, WB Dmin, and WB Dmean had significantly inferior OS in the multivariate analyses. CONCLUSIONS: HT Dmax, WB Dmin, and WB Dmean are promising indicators of lymphopenia and the survival of glioma patients undergoing postoperative IMRT. The necessity and feasibility of dosimetric constraints for HT and WB is warranted with further investigation.

Regulative mechanism of long non-coding RNA in gastric cancer and its role in traditional Chinese medicine / 实用肿瘤学杂志

Long non-coding RNA(LncRNA)is a class of RNA that cannot encode translated proteins with more than 200 nucleotides in length.It can be involved in the regulation of X chromosome silencing,chromatin modification,transcriptional activa-tion,transcriptional interference and other regulatory processes by binding to DNA,RNA or proteins.In recent years,more and more studies have confirmed that LncRNA plays an important role in the occurrence,development,invasion and metastasis of gastric cancer. At the same time,many studies have demonstrated LncRNA as the target of traditional Chinese medicine for the development and pro-gression of anti-gastric cancer.This review introduces the mechanism of LncRNA in the development and progression of gastric canc-er,and as a target for traditional Chinese medicine treatment prospects.

Saikosaponin D relieves unpredictable chronic mild stress induced depressive-like behavior in rats: involvement of HPA axis and hippocampal neurogenesis.

RATIONALE: Saikosaponin D (SSD), a major bioactive component isolated from Radix Bupleuri, has been reported to exert neuroprotective properties. OBJECTIVES: The present study was designed to investigate the anti-depressant-like effects and the potential mechanisms of SSD. METHODS: Behavioural tests including sucrose preference test (SPT), open field test (OFT) and forced swim test (FST) were performed to study the antidepressant-like effects of SSD. In addition, we examined corticosterone and glucocorticoid receptor (GR) levels to evaluate hypothalamic-pituitary-adrenal (HPA) axis function. Furthermore, hippocampal neurogenesis was assessed by testing doublecortin (DCX) levels, and neurotrophic molecule levels were also investigated in the hippocampus of rats. RESULTS: We found that unpredictable chronic mild stress (UCMS) rats displayed lost body weight, decreased sucrose consumption in SPT, reduced locomotive activity in OFT, and increased immobility time in FST. Chronic treatment with SSD (0.75, 1.50 mg/kg) remarkably ameliorated the behavioral deficiency induced by UCMS procedure. SSD administration downregulated elevated serum corticosterone levels, as well as alleviated the suppression of GR expression and nuclear translocation caused by UCMS, suggesting that SSD is able to remit the dysfunction of HPA axis. In addition, Western blot and immunohistochemistry analysis showed that SSD treatment significantly increased the generation of neurons in the hippocampus of UCMS rats indicated by elevated DCX levels. Moreover, hippocampal neurotrophic molecule levels of UCMS rats such as phosphorylated cAMP response element binding protein (p-CREB) and brain-derived neurotrophic factor (BDNF) were raised after SSD treatment. CONCLUSIONS: Together, Our results suggest that SSD opposed UCMS-induced depressive behaviors in rats, which was mediated, partially, by the enhancement of HPA axis function and consolidation of hippocampal neurogenesis.

Manganese-catalyzed synthesis of monofluoroalkenes via C-H activation and C-F cleavage.

The manganese-catalyzed α-fluoroalkenylation of arenes via C-H activation and C-F cleavage has been described. This protocol provides a very useful method for the synthesis of monofluoroalkenes with predominant unconventional E-isomer selectivity which complements the existing strategies for the access to these molecular architectures. In addition, the selectivity of ß-defluorination in the catalytic cycle not only determines the configurations of the products but also obviates the use of external oxidants, providing a good example in the exploitation of manganese-catalyzed redox-neutral C-H transformations.

[Atorvastatin improves reflow after percutaneous coronary intervention in patients with acute ST-segment elevation myocardial infarction by decreasing serum uric acid level].

Objective: To investigate the effect of atorvastatin on reflow in patients with acute ST-segment elevation myocardial infarction (STEMI) after percutaneous coronary intervention (PCI) and its relation to serum uric acid levels. Methods: One hundred and fourteen STEMI patients undergoing primary PCI were enrolled and randomly divided into two groups:55 cases received oral atorvastatin 20 mg before PCI (routine dose group) and 59 cases received oral atorvastatin 80 mg before PCI (high dose group). According to the initial serum uric acid level, patients in two groups were further divided into normal uric acid subgroup and hyperuricemia subgroup. The changes of uric acid level and coronary artery blood flow after PCI were observed. Correlations between the decrease of uric acid, the dose of atorvastatin and the blood flow of coronary artery after PCI were analyzed. Results: Serum uric acid levels were decreased after treatment in both groups (all P<0.05), and patients with hyperuricemia showed more significant decrease in serum uric acid level (P<0.05). Compared with the routine dose group, serum uric acid level in patients with hyperuricemia decreased more significantly in the high dose group (P<0.05), but no significant difference was observed between patients with normal serum uric acid levels in two groups (P>0.05). Among 114 patients, there were 19 cases without reflow after PCI (16.7%). In the routine dose group, there were 12 patients without reflow, in which 3 had normal uric acid and 9 had high uric acid levels (P<0.01). In the high dose group, there were 7 patients without reflow, in which 2 had normal uric acid and 5 had high uric acid (P<0.05). Logistic regression analysis showed that hyperuricemia was one of independent risk factors for no-reflow after PCI (OR=1.01, 95% CI:1.01-1.11, P<0.01). The incidence of no-flow after PCI in the routine dose group was 21.8% (12/55), and that in the high dose group was 11.9% (7/59) (P<0.01). Conclusion: High dose atorvastatin can decrease serum uric acid levels and improve reflow after PCI in patients with STEMI.

Antitumoural hydroxyapatite nanoparticles-mediated hepatoma-targeted trans-arterial embolization gene therapy: in vitro and in vivo studies.

BACKGROUND/AIMS: Absence of curative treatment creates urgent need for new strategies for unresectable hepatoma. Based on former discoveries of good liver cell compatibility, safety and tumour-specific inhibition of hydroxyapatite nanoparticles (nHAP), this work tries to make nHAP serve as gene vector in the hepatoma-targeted trans-arterial embolization (TAE) gene therapy to elevate and synergize the therapeutic efficacy of TAE and target gene therapy. METHOD: Following dosage and ratio optimization, polypolex formed by surface modified nHAP and p53 expressing plasmid was applied in vitro for human hepatoma HePG2 cell, and then in vivo for rabbit hepatic VX2 tumour by injection of polypolex/lipodoil emulsion to the hepatic artery in a tumour-target manner. RESULTS: In vitro, the polypolex transfected only about 5% HepG2 cells, but can elevate the inhibition of its growth and apoptosis in a much more degree while keeping safe to the normal hepatocyte line, L02. In vivo, the emulsion, with better dispersion than the polypolex and more specific tumour-target than lipiodol, mediated specific 4% p53 expression and antitumoural nanoparticle retention in the target tumour site, also significantly reduced tumour growth and prolonged the animal survival times more than the lipiodol (P < 0.05). CONCLUSIONS: In all, this new treatment based on nHAP can enhance therapeutic effect of HCC safely both in vitro and in vivo.

Relationship between expressions of estrogen and progesterone receptors and syndrome types of gastric carcinoma / 中西医结合学报

Objective: To explore the relationship between expressions of estrogen (ER) and progesterone (PR) receptors and syndromes of traditional Chinese medicine (TCM) in gastric carcinoma and to establish prognostic indicators for gastric carcinoma. Methods: A total of 72 patients with gastric carcinoma were divided into six groups according to TCM syndrome differentiation. Specimens were collected after operation and ER and PR protein expressions were detected by EnVision immunohistochemical method. Results: The common syndromes in female patients with gastric carcinoma were disharmony between liver and stomach, yin impairment due to stomach heat, and insufficiency of both qi and blood; while in males, interior retention of stagnant toxin, interior retention of phlegm and dampness, and deficiency-cold in spleen and stomach were common. Different TCM syndromes were related with gender (P<0.01), pathology (P<0.01), cell differentiation (P<0.05), infiltration depth (P<0.01), lymphaden metastasis (P<0.05), distant metastasis (P<0.05), and TNM stage (P<0.01). Deficiency and excess syndromes were associated with gender (P<0.05), pathology (P<0.05), tumor location (P<0.01) and TNM stage (P<0.05). The deficiency syndromes were common in female patients. The total positive rates of ER and PR expressions were 8.33% and 37.5% respectively. There was a significant difference in PR expression among different TCM syndromes (P<0.01). PR expression was significantly higher in the syndrome of yin deficiency due to stomach heat than in the other syndromes. The PR expressions in deficiency syndromes were significantly higher than those in excess syndromes (P<0.01). No correlation was found between ER expression and different TCM syndromes. Conclusion: There is a correlation between PR expression and different TCM syndromes in gastric carcinoma.
