Objective:To analyze the clinical characteristics of patients with acute glyphosate herbicide poisoning and the differences in the severity of poisoning.Methods:A retrospective analysis was performed on patients with acute glyphosate herbicide poisoning admitted to the First Affiliated Hospital of Zhengzhou University from January 2014 to December 2020. The general information, exposure time, poisoning dose, poisoning cause, poisoning route, clinical manifestations, laboratory examination results during hospitalization, treatment measures, hospital stays and prognosis of the patients were collected. The patients were graded according to the poisoning severity scoring standard of Chinese Expert Consensus on Diagnosis and Treatment of Acute Poisoning in 2016. The highest severity score during hospitalization was used as the final grade. According to the final grade, asymptomatic and mild patients were included in the mild group, and moderate, severe and death patients were included in the severe group. The independent sample T test or Mann-Whitney U test was used for measurement data, and χ2 test or Fisher's exact test was used for counting data. The differences of general data and clinical data between the two groups were compared. Results:According to the inclusion and exclusion criteria, 83 patients with acute glyphosate herbicide poisoning were selected as the study subjects. All patients survived, mainly mild poisoning (56.6%), with a male to female ratio of 33∶50, and an average age of 39 years. The number of poisoning cases increased yearly (the highest in 2019), and most cases occurred in spring and summer. The main cause of poisoning was suicide (71.1%), direct oral administration (83.1%) was the primary route of poisoning, and the dominating clinical manifestations were digestive symptoms (71.1%). Laboratory tests showed increased white blood cell count (WBC), neutrophil percentage (NEUT %) and D-dimer, and decreased hemoglobin and potassium. Compared with the mild group, patients in the severe group were older [(51±17) years vs. (35±19) years], had a higher proportion of suicide and direct oral administration, a longer hospital stay [8.0 (4.8, 12.0) d vs. 3.0 (2.0, 5.5) d], a higher dose of poisoning [200.0 (50.0, 200.0) mL vs. 30.0 (11.3, 57.5) mL], and higher NEUT % within 24 h of admission [(83.4±10.4) vs. (73.2±12.8)]. The increase of WBC, NEUT %, aspartate aminotransferase, prothrombin time, D-dimer and the decrease of serum potassium were more common in the severe group than the mild group, with statistical significance (all P<0.05). Conclusions:The number of patients with acute glyphosate herbicide poisoning is increasing yearly. Generally, the condition is mild and the prognosis is satisfying. The severity is more serious in the middle-aged and elderly patients andthose with direct oral administration, high toxic dose, and high NEUT % within 24 h of admission. Severe poisoning is more likely to cause changes in laboratory indicators.

A large number of investigations and studies abroad have focused on the quality of life of breast cancer long-term survivors (BCLS) and its influencing factors. Although their long-term quality of life has been improved, the improvement of their quality of life is affected by many factors. At present, there are few researches on BCLS in China. This research systematically searches CNKI, Wanfang, PubMed and Web of Science, includes relevant literature on quality of life of BCLS in recent years and describes the current domestic and foreign research status of quality of life of BCLS. It reviews from four aspects, including general demographic factors, disease-related factors, psychosocial factors and exercise, in order to provide reference for the follow-up research and practice.

Objective:To investigate the effect of Relative Bedrest Condition Morita Therapy(RBCMT) on the improvement of depression and anxiety symptoms and personality in patients with recurrent depression disorder.Methods:Seventy patients with recurrent depressive disorder hospitalized in Kailuan Mental Health Center were randomly divided into study group and control group( n=35 in each group) from June to October, 2019.The study group was given RBCMT on the basis of conventional treatment and nursing.The Eysenck personality questionnaire (EPQ), Hamilton depression scale (HAMD) and Hamilton anxiety scale (HAMA) were used to assess the clinical symptoms and personality characteristics of the patients and to analyze and compare them. Results:(1) EPQ score in each dimension: There were significant differences within group among different time in introverted and extroverted dimension (study group: baseline: 46.14±10.99, the fifth weekend: 50.43±8.86, the eighth weekend: 53.86±7.08, F=6.291, P=0.003.Control group: baseline: 45.29±8.99, the fifth weekend: 48.29±8.31, the eighth weekend: 50.29±7.57, F=3.211, P=0.044) and neuroticism dimension score (study group: baseline: 60.14±5.49, the fifth weekend: 53.29±4.53, the eighth weekend: 50.57±4.33, F=36.809, P<0.001.Control group: baseline: 60.29±6.18, the fifth weekend: 55.86±6.00, the eighth weekend: 53.14±5.30, F=13.353, P<0.001) among different time points in the group.Neuroticism scores between the two groups at the same time were statistically significant(the fifth weekend: F=4.095, P=0.047, the eighth weekend: F=4.940, P=0.030). After 8 weeks of inclusion, there was a statistically significant difference between the two groups in the score of introverted and extroverted dimension ( F=4.157, P=0.045). There was no significant difference in the score of spiritual quality dimension at different time within the group or at the same time point between the groups.(2)HAMD score: There were statistically significant differences within group among different time(study group: baseline: 32.00±4.04, the fifth weekend: 15.23±5.01, the eighth weekend: 9.31±3.15, F=282.376, P<0.001.Control group: baseline: 31.91±4.59, the fifth weekend: 17.86±5.11, the eighth weekend: 11.17±3.64, F=195.019, P<0.001), and the differences between the two groups at the same time were statistically significant (the fifth weekend: F=4.724, P=0.033, the eighth weekend: F=5.205, P=0.026). (3)HAMA score: There were statistically significant differences within group among different time(study group: baseline: 18.69±8.87, the fifth weekend: 10.34±5.34, the eighth weekend: 7.97±2.98, F=28.679, P<0.001.Control group: baseline: 18.60±8.02, the fifth weekend: 13.31±6.35, the eighth weekend: 10.37±4.86, F=14.241, P<0.001). The difference between the two groups at the same time point was statistically significant (the fifth weekend: F=4.161, P=0.045, the eighth weekend: F=8.315, P=005). (4)Multiple linear regression results indicated that RBCMT ( β=-0.312, t=-2.360, P=0.022) and introverted and extroverted dimension personality ( β=-0.334, t=-2.355, P=0.022) were the influencing factors of HAMA. Conclusion:Compared with the conventional treatment, the Relative Bedrest Condition Morita Therapy can reduce the anxiety symptoms and improve the depressive symptoms by enhancing the extraversion personality characteristics of the patients.

Objective: To explore the correlation of monocyte to HDL-C ratio (MHR) and post-operative slow lfow or no relfow in patients with ST-segment elevation myocardial infarction (STEMI) after percutaneous coronary intervention (PCI). Methods: A total of 216 STEMI patients treated in our hospital from 2014-10 to 2016-05 were enrolled. The patients were divided into 2 groups: Slow lfow or no relfow group, the patients with TIMI grade≤2,n=43 and Normal lfow group, n=173. Receiver operating characteristic (ROC) curve was performed to assess the best cut-off value for MHR predicting slow lfow or no relfow with its sensitivity and speciifcity; Logistic regression analysis was conducted to studied weather MHR could be used as an independent risk factor for coronary slow lfow or no relfow in STEMI patients after PCI. Results: Compared with Normal lfow group, Slow lfow or no relfow group had the higher MHR (18.6±9.8) vs (10.9±5.5), P<0.001. Univariate Regression analysis indicated that MHR was a risk factor of slow lfow or no relfow occurrence (OR=2.22, 95% CI 1.58-3.28); multivariate regression analysis presented that MHR was an independent risk factor of slow lfow or no relfow occurrence (OR=1.55, 95% CI 1.01-2.38). ROC curve showed that the best cut-off value for MHR predicting slow lfow or no relfow occurrence was 13.37 with the sensitivity and speciifcity at 67.4% and 70.5% respectively, the area under curve (AUC) was 0.734, 95% CI 0.646-0.822. Conclusion: MHR was an independent risk factor for slow lfow or no relfow occurrence in STEMI patients after PCI.

Objective:To explore the mechanism of the cytotoxicity of human NK cells induced by atorvastatin to colon cancer cell lines. Methods:After colon cancer cells (HCT-116,SW-480,Caco-2) were cultured with different concentrations of atorvastatin, CCK-8 assay was used to assess the effect of atorvastatin on growth of colon cancer cells. The amplification of human NK cells was induced by SCGM medium in vitro. Automatic biochemical analyzer was applied to test the cytotoxicity of NK cells to colon cancer cells which cultured with different concentration of atorvastatin. FCM was used to detect the expression rate of MICA/B on the cells. Results:(1) The cultivation of NK cells:The proportion of NK cells attained to 93. 1% from 4. 5% after cultured for 10 days. (2) The effects of atorvastatin on the growth of the colon cancer cells:After cultured with atorvastatin,the inhibition rate of HCT-116 cells was higher than that in control when the density of atorvastatin increased from 5 μmol/L to 40 μmol/L after 48 h and from 1. 25 μmol/L to 40 μmol/L after 96 h ( P<0. 05 ) . Correlation analysis showed that the concentration of atorvastatin and the growth inhibition rate of HCT-116 cells were positively correlated(r[48 h]=0. 13,r[96 h]=0. 22,P<0. 05). (3) The cytotoxicity of NK cells to colon cancer cells effected after atorvastatin: In different atorvastatin concentrations groups,the cytotoxicity of NK cells to three colon cancer cell lines was all higher than that in control ( P<0. 05 ) . The atorvastatin concentration was from 2. 5 μmol/L to 10 μmol/L for HCT-116 cells,from 5 μmol/L to 20μmol/L for SW-480 cells,and from 2. 5μmol/L to 20μmol/L for Caco-2 cells. Among the three cell lines, the cytotoxicity of NK cells to HCT116 was the highest in the same concentration. (4)NK cells by atorvastatin cutting statins 96 h,the concentration of 20 mmol/L and 40 mmol/L inhibition rate was higher than that of control group,more than other groups on NK cell growth without significant effect. ( 5 ) The impact of atorvastatin on MICA/B expression of colon cancer cells: After cultured with different concentrations of atorvastatin,the expression of MICA/B on colon cancer cells was higher than that in control(P<0. 05). The concentration was 2. 5μmol/L and 5μmol/L for HCT-116 cells,10μmol/L and 20μmol/L for SW-480 cells,and from 2. 5μmol/L to 40 μmol/L for Caco-2 cells. Conclusion:Atorvastatin could inhibit the growth of colon cancer cells (HCT-116,SW-480 and Caco-2) in a dose-dependent manner;and it could enhance the cytotoxicity of NK cells to colon cancer cells;it also could promote the expression of MICA/B of colon cancer cells,and improve the immunogenicity of colon cancer cells.

AIM:Increasing evidence indicates that inflammation contributes to the initiation and perpetuation of atrial fibrillation ( AF) .Al-though tumor necrosis factor ( TNF)-αlevels are increased in patients with AF , the role of TNF-αin the pathogenesis of AF remains unclear.Recent research has revealed that T-type Ca2+currents ( ICa,T ) play an important role in the pathogenesis of AF .METH-ODS:In this study , we used the whole-cell voltage-clamp technique and biochemical assays to explore the role of TNF-αin the regula-tion of ICa,T in atrial myocytes.RESULTS:We found that compared with sinus rhythm (SR) controls, T-type calcium channel (TCC) subunit mRNA levels were decreased , while TNF-αexpression levels were increased , in human atrial tissue from patients with AF .In murine atrial myocyte HL-1 cells, after cultured for 24 h, 12.5, 25 and 50 μg/L TNF-αsignificantly reduced the protein expression levels of the TCC α1G subunit in a concentration-dependent manner .The peak current was reduced by the application of 12.5 or 25μg/L TNF-αin a concentration-dependent manner [from ( -15.08 ±1.11) pA/pF in controls to ( -11.89 ±0.83) pA/pF and (-8.54 ±1.55) pA/pF in 12.5 and 25 μg/L TNF-αgroups, respectively].TNF-αapplication also inhibited voltage-dependent inactivation of ICa,T shifted the inactivation curve to the left .CONCLUSION:These results suggest that TNF-αis involved in the path-ogenesis of AF, probably via decreasing ICa,T function in atrium-derived myocytes through impaired channel function and down -regula-tion of channel protein expression .This pathway thus represents a potential pathogenic mechanism in AF .

Objective To evaluate the feasibility of application of single and dual antiplatelet aggregation therapy in high sensitive C-reactive protein (hs-CRP) level in patients with angina pectoris. Methods Ninety-six hospitalized patients with angina 6~48 h (hs-CRP< 2 mg/L) were selected and randomly divided into single aspirin group (aspirin 100 mg/d, n=48) and aspirin plus clopidogrel combination therapy group (aspirin 100 mg/d and clopidogrel 75 mg/d, n=48). The efficacy was evaluated after 30-day treatment. Data of composite end points were analyzed by follow-up in patients within 6 months. Results The total effective rates were 85.42%for combination therapy group and 81.25%for single aspirin group. There was no significant difference in total effective rate between two groups (P>0.05). There were no significant differences in events of composite end points in patients after treatment between two groups (P > 0.05). Conclusion For angina pectoris patients with hs-CRP<2 mg/L, the risk of cardiovascular events is relatively little. There is no obvious difference in curative effect between single and dual antiplatelet aggreration therapies.
