Objective To observe effects of Heyutai Fuzhu Jiangtang Tablets combined with metformin in insulin resistance (IR); To discuss its mechanism of action. Methods 6–7 week old male ZDF (fa/fa) rats were randomly divided into model group,metformin group,Heyutai Fuzhu Jiangtang Tablets group(Jiangtang Tablets group),and metformin combined with Heyutai Fuzhu Jiangtang Tablets group.ZDF(fa/+)rats were chosen as normal group.Each medication group was given relevant medicine for gavage for 6 weeks. Body weight, FBG, TG, TC, FFA, FINS, HOMA-IR, OGTT and HE staining were tested. HE staining was used to observe the pathological changes of skeletal muscle. RT-PCR and Western blot were used to detect skeletal muscle corresponding gene and protein expression. Results Compared with Jiangtang Tablets group and metformin group, TC, FFA, FBG, and HOMA-IR in metformin combined with Heyutai Fuzhu Jiangtang Tablets group decreased significantly (P<0.05, P<0.01). Blood glucose level and AUC significantly decreased at each time point in OGTT. HE staining of skeletal muscle fibers arranged in order; nucleus increased and internal movement was not significant, without obvious infiltration of inflammatory cells. Expressions of skeletal muscle InsR, Akt, and Glut4 mRNA expression increased (P<0.05, P<0.01). Expressions of skeletal muscle p-InsR, p-Akt, and Glut4 protein expression increased (P<0.05, P<0.01). Conclusion Heyutai Fuzhu Jiangtang Tablets combined with metformin can improve IR in type 2 diabetic rats, and the effect is better than single-application.

Objective To evaluate the effects of nasal mometasone furoate on moderate to severe allergic rhinitis. Methods Patients with moderate to severe allergic rhinitis were enrolled and received mometasone furoate nasal spray 200 μg once daily for four weeks. Four hundreds and sixty-three patients completed the study. We weekly interviewed the patients to evaluate the symptoms, and the affection of disease on night sleep and daily life. Mini Rhinoconjunctivitis Quality of Life Questionnaire (Mini-RQLQ) and Nocturnal Rhinoconjunctivitis Quality of Life Questionnaire (NRQLQ) were used to evaluate the quality of life. Results The individual and total symptomatic scores of week 1, week 2 and week 4 decreased compared with baseline. The scores of Mini-RQLQ and NRQLQ of week 1, week 2 and week 4 decreased compared with baseline too. The scores of the next visit were significantly lower than those of the previous visit (P < 0. 01 ) . Conclusions A four-week administration of mometasone furoate nasal spray can effectively treat allergic rhinitis.

Isorhapontigenin (ISO) is suggested to have many different kinds of pharmacology activities, such as anti-inflammatory effect, anti-oxidation effect and anti-cancer effect. This paper mainly discussed the transport mechanism of ISO in Caco-2 cell models. The concentration of ISO was determined by UPLC method with PDA detector at 310 nm, and then the apparent permeability coefficient Papp was calculated. The cytotoxic of different concentrations of ISO was investigated on Caco-2 cells to determine the concentration of drug administration. The effects of ISO concentration, time, temperature and transporter inhibitors on the transport of ISO were investigated. The test results showed that, ISO didn't have significant cytotoxicity at 10-60 μmol•L ⁻¹ in 14 hours. The transportation of ISO on Caco-2 cells was related to the concentration to a certain extent. Papp of ISO was higher than 10×10-6 cm•s ⁻¹ and ISO was absorbed easily by Caco-2 cells. The transport volume of ISO at BL side reached maximum at 3 h and was slightly decreased at 6 h. Papp (AP-BL) and Papp(BL-AP) at 4 ℃ were lower than those at 37 ℃. Papp (AP-BL) of ISO was significantly increased after adding P-gp inhibitor verapamil and Papp (BL-AP) of ISO was significantly decreased after adding MRP-2 inhibitor (probenecid or MK-571). The results suggested that transport mode of ISO was mainly passive diffusion in Caco-2 cell models, and P-gp and MRP may be involved in the transport of ISO.

Objective: To investigate the predicting value of different risk prediction models for short-term death in patients with ST-segment elevation myocardial infarction (STEMI) complicated by cardiogenic shock and treated with extracorporeal membrane oxygenation (ECMO). Methods: This study was a retrospective case-control study. Forty patients with STEMI complicated by cardiogenic shock who hospitalized in the First Affiliated Hospital of Zhengzhou University from April 2017 to August 2021 and treated with percutaneous coronary intervention (PCI) and ECMO, were enrolled in this study. Patients were divided into survival group and death group according to their clinical outcomes at 30 days after ECMO implantation, and clinical data of the two groups were collected and analyzed. Receiver operating characteristic (ROC) curve and decision curve analysis (DCA) were used to compare the predictive value of ACEF, AMI-ECMO, Encourage and SAVE risk scores for mortality at 30 days after ECMO implantation. According to the evaluation results of DCA, the optimal risk score was selected. Kaplan-Meier curve estimating the 30-day survival after ECMO implantation was plotted by grouping risk scores with reference to previous literatures. Results: A total of 40 patients with STEMI combined with cardiogenic shock were included, age was (57.4±16.7) years, 31 (77.5%) patients were male, there were 21 (52.5%) patients in the death group and 19 (47.5%) in the survival group. Compared with the survival group, patients in the death group had higher lactic acid values, higher proportion of anterior descending artery or left main artery lesions, and a higher proportion of acute renal failure and continuous renal replacement therapy during hospitalization (all P<0.05). Compared with survival group, ACEF, AMI-ECMO and Encourage scores were higher in death group, SAVE score was lower in death group (all P<0.05). The ROC curve analysis showed that the area under the curve (AUC) of ACEF, AMI-ECMO, Encourage and SAVE scores in predicting mortality were 0.707, 0.816, 0.757, and 0.677 respectively (P>0.05). ACEF score demonstrated the highest sensitivity (90.5%) and Encourage score exhibited the highest specificity (89.5%). DCA indicated that the AMI-ECMO and Encourage scores had the best performance in predicting the 30-day mortality after ECMO therapy. Kaplan-Meier survival curve analysis showed that the 30-day mortality after ECMO implantation increased with the increase of AMI-ECMO and Encourage scores (log-rank P≤0.001). Conclusions: The 4 scoring systems are all suitable for predicting 30-day mortality after VA-ECMO therapy in patients with ST-segment elevation myocardial infarction complicated by cardiogenic shock. Among them, AMI-ECMO and Encourage scores have better predicting performance.

To investigate the effect of resolution components, such as Açaí oil, alcohol extract and water extract, on the temperature tendency animal behavior and intrinsic biochemical indexes, such ascyclic nucleotides and metabolic level, in mice with deficiency-heat and deficiency-cold syndrome, in order to study the characteristics of the cold and heat properties of each resolution component of Açaí and the material basis of cooling. KM mice were randomly divided into 12 groups, namely blank group, deficiency-heat model group, deficiency-heat+Açaí group, deficiency-heat+Açaí oil group, deficiency-heat+Açaí alcohol extract group, deficiency-heat+Açaí water extract group, deficiency-cold model group, deficiency-cold+Cinnamomi Cortex group, deficiency-cold+Açaí group, deficiency-cold+Açaí oil group, deficiency-cold+Açaí alcohol extract group, deficiency-cold+Açaí water extract group. The mice in deficiency-heat group were given thyroid tablet solution(160 mg·kg~(-1)), the mice in deficiency-cold group were given hydrocortisone solution(25 mg·kg~(-1)) through gastric perfusion every afternoon for 14 days, and each administration group was given the corresponding drug. The temperature tendency, cyclic nucleotides and metabolic level of animals were measured after the experiment. The Açaí alcohol extract was consistent with the Açaí powder, with a regulatory effect on the deficiency-heat model mice; Açaí oil and its water extract were consistent with Cinnamomi Cortex, with a regulatory effect on the deficiency-cold model mice. In this study, based on the parable theory of traditional Chinese medicine's properties and tastes, property of alcohol extract of Açaí was cool, while the property of oil and water extract were warm, the alcohol extract of Açaí was the material basis of Açaí cold medicine by the methods of homogeneous comparison and heterogeneous disproval.

Objective: To evaluate the efficacy within the first 24 h post extracorporeal membrane pulmonary oxygenation (ECMO) and the impact of early efficacy on the prognosis of adult patients with fulminant myocarditis (FM). Methods: This retrospective case analysis study included hospitalized patients (age≥18 years) who were diagnosed with fulminant myocarditis from November 2016 to May 2021 in the First Affiliated Hospital of Zhengzhou University. Patients were divided into survival or non-survival groups according to treatment outcomes. The age, sex, treatments, drug use, ECMO use, clinical and laboratory data (before and 24 h after the use of ECMO) were analyzed. The change rate of clinical and laboratory data after 24 h use of ECMO was calculated to find differences between two groups. Multivariate logistic regression was used to analyze the related factors with in-hospital death and complication between the two groups. Results: A total of 38 FM patients treated with ECMO were included. There were 23 cases (60.5%) in the survival group, aged (39.6±13.7) years, and 17 (73.9%) cases were female. The total ECMO time was (134.4±71.3)h. There were 15 cases (39.5%) in non-survival group, aged (40.0±15.8) years, and there were 12(80.0%) female, the ECMO time was (120.1±72.4) h in this group. The proportion of tracheal intubation and continuous renal replacement therapy in the survivor group and dosage of norepinephrine within 24 h after ECMO implantation were significantly less than in non-survival group (all P<0.05). There was no significant difference in all efficacy related biochemical indexes between two groups before ECMO use. The levels of lactic acid, procalcitonin, creatinine, alanine aminotransferase, aspartate aminotransferase, creatine kinase-MB, cardiac troponin I and N-terminal B-type natriuretic peptide prosoma were significantly less in survival group than in non-survival group at 24 h after the use of ECMO (all P<0.05). Results of multivariate logistic regression analysis showed that the higher 24 h change rate of creatinine (OR=0.587, 95%CI 0.349-0.986, P=0.044) and creatine kinase-MB (OR=0.177, 95%CI 0.037-0.841, P=0.029) were positively correlated with reduced risk of in-hospital mortality. The central hemorrhage and acute kidney injury in survival group were less than in non-survivor group (P<0.05). Conclusions: After 24 h early use of ECMO in FM patients, the improvement of various efficacy related biochemical test indexes in the survival group was better than that in the non-survival group. Faster reduction of creatine kinase-MB and creatinine values within 24 h ECMO use is positively correlated with reduced risk of in-hospital mortality in adult patients with FM.

OBJECTIVES: To investigate the cerebral metabolism in the patients with type 2 diabetes mellitus-associated cognitive dysfunction (T2DACD) and explore the mechanism of electroacupuncture (EA) at the acupoints for Tiaozang Xingshen (adjusting zangfu function and rescuing the spirit) in treatment of T2DACD, using magnetic resonance spectroscopy. METHODS: Fifteen patients with T2DACD (observation group) and 22 healthy subjects (control group) were enrolled. In the observation group, the patients were treated with EA for Tiaozang Xingshen at Baihui (GV 20) and Shenting (GV 24), and bilateral Feishu (BL 13), Pishu (BL 20), Shenshu (BL 23), Zusanli (ST 36), Sanyinjiao (SP 6), Hegu (LI 4) and Taichong (LR 3). EA was operated with disperse-dense wave, 2 Hz/100 Hz in frequency and 0.1 mA to 1.0 mA in current intensity; 30 min each time, once daily. One course of EA consisted of 5 treatments, at the interval of 2 days and the intervention lasted 8 courses. Before treatment in the control group, before and after treatment in the observation group, the score of Montreal cognitive assessment scale (MoCA), the score of clinical dementia rating (CDR), Flanker paradigm, Stroop paradigm, Nback paradigm, the score of self-rating anxiety scale (SAS), the score of self-rating depression scale (SDS), and the score of Hamilton depression rating scale (HAMD) were evaluated separately; the glycolipid metabolic indexes (fasting plasma glucose [FPG], glycosylated hemoglobin type A1c [HbA1c], total cholesterol [TC], triacylglycerol [TG], high-density lipoprotein cholesterol [HDL-C] and low-density lipoprotein cholesterol [LDL-C]) were determined；with the magnetic resonance spectroscopy technique adopted, the metabolites in the basal ganglia area were detected. The correlation analysis was performed for the metabolite values with MoCA score, CDR score , Flanker paradigm, Stroop paradigm, and Nback paradigm. RESULTS: Before treatment, compared with the control group, in the observation group, MoCA score was lower (P<0.001), CDR score and the levels of FPG and HbA1c were higher (P<0.001); the reaction times of Flanker non-conflict, Flanker conflict, Stroop neutrality, Stroop congruence, Stroop conflict, and 1-back were prolonged (P<0.05, P<0.001), and the accuracy of Flanker conflict, Stroop conflict, and 1-back decreased (P<0.05, P<0.01); the ratio of N-acetyl aspartate (NAA) to creatine (Cr) in the left basal ganglia area was dropped (P<0.001), and that of myo-inositol (MI) to Cr in the right side increased (P<0.05). In the observation group after treatment, compared with the levels before treatment, MoCA score was higher (P<0.001), the scores of CDR, SAS and HAMD were reduced (P<0.01, P<0.05), the reaction times of Flanker conflict and Stroop conflict shortened (P<0.001, P<0.05), and the accuracy of Flanker conflict and 1-back increased (P<0.001, P<0.05); the ratio of NAA to Cr in the left basal ganglia area and that of the gamma-aminobutyric acid (GABA) to Cr in the right increased (P<0.05), that of MI to Cr in the right decreased (P<0.05). Before treatment, in the observation group, the ratio of MI to Cr in the right basal ganglia area was positively correlated with the reaction time of Stroop congruence (r=0.671, P=0.012) and this ratio was positively correlated with the reaction time of Stroop conflict (r=0.576, P=0.039). CONCLUSIONS Electroacupuncture for "adjusting zangfu function and rescuing the mind" improves the cognitive function of T2DACD patients, which may be related to the regulation of NAA, MI and GABA levels in the basal ganglia.

OBJECTIVE: To assess the activation function of specific tumor polypeptide for dendritic cell vaccine on lymphocytes proliferation, production of cytokines and killing activity in vitro by using dendritic cells as antigen presenting vector. METHODS: Peripheral blood dendritic cells (DC) and cytokine-induced killer (CIK) were isolated and cultured by adherent culture method; CCK-8 method was used to assess the proliferation function of lymphocytes and the killing function of lymphocytes to tumor cells; enzyme-linked immunospot assay method was used to evaluate the secretion function of cytokines. The experiment was divided into tumor polypeptide group (peptide with DC-CIK), DC-CIK group and CIK group. RESULTS: With presence of interleukin-2 (IL-2) in the culture system, the lymphocyte proliferation of the three groups was obvious. The absorbance at 450 nm of tumor polypeptide group was significantly higher than that of CIK group at the time points day 4 and day 6 (day 4: Z=-3.79, P < 0.001; day 6: Z =-2.95, P < 0.01). The absorbance at 450 nm of group tumor polypeptide was significantly higher than that of DC-CIK group on day 4 (Z=-2.02, P < 0.05). Without IL-2 in the culture system, lymphocytes proliferated slowly in all the three groups, and there was no significant difference in 450 nm absorbance at each time point. The levels of IL-4 (Z=-2.61, P < 0.01), granulocyte-macrophage colony-stimulation factor (GM-CSF, Z=-3.85, P < 0.001), interferon- γ (IFN- γ, Z=-3.56, P < 0.001) and tumor necrosis factor-α (TNF-ɑ, Z=-3.40, P < 0.001) of tumor polypeptide group were higher than those of CIK group. There was no significant difference in the production of cytokines except IL-4 (Z=-2.15, P < 0.05) when tumor polypeptide group was compared with DC-CIK group. The production of IFN-γ (Z=-2.44, P < 0.05), TNF-ɑ (Z=-2.26, P < 0.05) and GM-CSF (Z=-3.73, P < 0.001) in DC-CIK group were higher than those of CIK group. Although there was no significant difference in killing activity between tumor polypeptide group, DC-CIK group and CIK group at hour 18 and hour 24, and the killing activity of tumor polypeptide group was higher than that of the other two groups. CONCLUSION Tumor peptide combined with dendritic cells can improve the proliferation activity of CIK cells in vitro, and increase the secretion of several cytokines.

Objective: To analyze the prevalence of dry and wet age-related macular degeneration (AMD) in patients with diabetes, hypertension and hyperlipidemia, and to analyze the risk factors for AMD. Methods: A population-based cross-sectional epidemiologic study was conducted involving 14,440 individuals. We assessed the prevalence of dry and wet AMD in diabetic and non-diabetic subjects and analyzed the risk factors for AMD. Results: The prevalence of wet AMD in diabetic and non-diabetic patients was 0.3% and 0.5%, respectively, and the prevalence of dry AMD was 17% and 16.4%, respectively. The prevalence of wet AMD in healthy, hypertensive, hyperlipidemic, and hypertensive/hyperlipidemic populations was 0.5%, 0.3%, 0.2%, and 0.7%, respectively. The prevalence of dry AMD in healthy, hypertensive, hyperlipidemic, and hypertensive/hyperlipidemic populations was 16.6%, 16.2%, 15.2%, and 17.2%, respectively. Age, sex, body mass index, and use of hypoglycemic drugs or lowering blood pressure drugs were corrected in the risk factor analysis of AMD. Diabetes, diabetes/hypertension, diabetes/hyperlipidemia, and diabetes/hypertension/hyperlipidemia were analyzed. None of the factors analyzed in the current study increased the risk for the onset of AMD. Conclusion There was no significant difference in the prevalence of wet and dry AMD among diabetic and non-diabetic subjects. Similarly, there was no significant difference in the prevalence of wet and dry AMD among subjects with hypertension and hyperlipidemia. Diabetes co-existing with hypertension and hyperlipidemia were not shown to be risk factors for the onset of dry AMD.
