Objective To investigate the efficacy of proton pump inhibitors (PPI) combined with flupethixol melitracen in the treatment of non-erosive gastroesophageal reflux disease (NERD) with anxiety and depression.Methods Fifty six NERD patients with anxiety and depression were evenly divided into the positive treatment group and positive control group.Thirty NERD patients without anxiety and depression were set as negative control group.Both flupethixol melitracen (20 mg per day after breakfast) and PPI esomeprazole magnesium (20 mg per day,20 minutes before breakfast) were administrated in positive treatment group.Only esomeprazole magnesium was given in positive control group and negative control group and the dosage was same as that of positive treatment group.The treatment course of three groups was eight weeks.Before and after the treatment,the symptoms of patients were scored according to gastroesophageal reflux disease questionnaire (GERDQ),Hamilton anxiety scale (HAMA),Hamilton depression scale (HAMD) and Pittsburgh sleep quality index (PSQI).Adverse effects were also observed.Variance analysis was performed for the comparison among three groups.Variance analysis or Post-hoc analysis were used for comparison between two groups.Results The differences of different score value before and after treatment of three groups were statistically significant in total score of GERD Q,score of type A,score of type C,score of HAMA,score of HAMD and PSQI (F=6.32,3.93,5.63,49.61,78.69 and 7.07,all P＜ 0.05).The differences of the score value before and after treatment of positive treatment group in total score of GERD Q,score of type A,score of type C,score of HAMA,score of HAMD and PSQI (4.24±2.05,3.16±1.46,1(0,3),9.32±3.21 and 8.88±2.92) were all higher than those of positive control group (2.38±2.22,1.68±1.33,0(0,2),3.72±2.95 and 3.84±1.97) and negative control group (2.32±2.18,2.48±1.34,0(0,1),2.36±1.25 and 2.36±0.79).And the differences were statistically significant (positive treatment group vs positive control group:Post-hoc analysis,P=0.002,0.022,0.003,0.002 and 0.002; positive treatment group vs negative control group:Post-hoc analysis,P=0.001,0.021,0.004,0.001 and 0.001).The difference of the score value before and after treatment of positive treatment group in PSQI (4 (2,6)) was higher than that of negative control group (2 (1,3),Post-hoc analysis,P=0.001).Two cases of positive treatment group had mild dizziness and the symptom relieved after three to four days.Conclusions For NERD patients with anxiety and depression,anti-depression drug flupenthixol melitracen can be used and the effect is superior to using PPI alone.

Metabolic syndrome(MS)is a complex syndrome based on metabolic disorders in the human body,and is a risk factor for cardiovascular diseases and even certain tumors,with a complicated etiology and unclear pathogenesis.Helicobacter pylori(Hp)is one of the most common pathogenic bacteria,closely associated with the occurrence and development of various diseases.Currently,there are numerous studies both domestically and internationally on the relationship between Hp and MS and its components.Most studies suggest that there is an association between Hp and MS and Hp influences the occurrence and development of MS through multiple pathways.Eradicating Hp may become a new option for treating MS.Based on recent studies from both domestic and international sources,this paper discusses the association between Hp and MS,analyzes the effects of Hp on obesity,blood glucose,blood lipids,and blood pressure,and aims to provide new ideas for the prevention and treatment of MS.

Animal experiments are essential tools in biomedical research, serving as a bridge between basic research and clinical trials. Systematic reviews and meta-analyses (SRs/MAs) of animal experiments are crucial methods for integrating evidence from animal experiment, which can facilitate the translation of findings into clinical research, reduce translational risks, and promote resource integration in basic research. With the continuous development of the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) methodology, its application in SRs/MAs of animal experiments has gained increasing attention. This article first outlines the principles and specific applications of the GRADE methodology in SRs/MAs of animal experiments, including qualitative descriptive systematic reviews, meta-analyses, and network meta-analyses. It then deeply analyzes the misuse of the GRADE methodology in practice, including incorrect evidence grading, improper classification of evidence, misapplication in qualitative systematic reviews, inconsistencies between the documentation of the upgrading and downgrading process and results, and inappropriate use for making recommendations. Furthermore, this article comprehensively discusses the factors influencing the grading of evidence certainty in SRs/MAs of animal experiments, including the impact of bias risk, indirectness, inconsistency, imprecision, and publication bias on evidence downgrading, as well as the role of large effect sizes and cross-species consistency in evidence upgrading. Finally, in response to the issues discussed, improvement strategies are proposed, including further research and optimization of the GRADE methodology for SRs/MAs of animal experiments, the development of reporting guidelines tailored to the characteristics of SRs/MAs in animal experiment research, and enhanced professional training for researchers in the GRADE methodology. This article aims to improve the quality of evidence in SRs/MAs of animal experiments, strengthen their reliability in clinical decision-making, and promote the more efficient translation of findings from animal experiment research into clinical practice.
