RESUMO
Objective To investigate the efficacy and safety of sacubitril valsartan in the treatment of heart failure(HF)of midrange ejection fraction(HFmrEF)in patients after acute myocardial infarction(AMI).Methods A total of 102 patients with HFmrEF after AMI were divided into the control group and the experimental group,with 51 cases in each group.The control group was given conventional treatment for AMI and anti-HF treatment,and the angiotensin-converting enzyme inhibitor(ACEI)/angiotensin Ⅱ receptor blocker(ARB)was used without contraindications.The experimental group was replaced by ACEI/ARB with sacubitril valsartan on the basis of the control group.After 6 months of treatment,the total effective rates of the two groups after treatment were analyzed,and the cardiac function,N-terminal pro-brain natriuretic peptide(NT-proBNP)and serum inflammatory factor C-reactive protein(CRP)were compared before and after treatment.The occurrence of adverse reactions after treatment was recorded.Kaplan-Meier method was used to analyze the cumulative cardiovascular mortality,HF rehospitalization rate and end-event-free survival after 6 months of treatment in two groups.Results After treatment,there was no significant difference in the occurrence of adverse reactions between the two groups(P>0.05).The total effective rate was higher in the experimental group than that of the control group(P<0.05).Compared with before treatment,left ventricular ejection fraction(LVEF),stroke volume(SV),mitral diastolic blood flow velocity E peak and A peak ratio(E/A)and 6 min walking distance(6MWD)were increased in the two groups,and left ventricular end-diastolic diameter(LVEDD)and left atrial diameter(LAD)were decreased in the two groups after treatment(all P<0.05).After treatment,LVEF,SV,E/A and 6MWD were higher in the experimental group than those in the control group(P<0.05).LVEDD and LAD were lower than those in the control group(all P<0.05).Compared with results before treatment,NT-proBNP and CRP were decreased after treatment in the experiment group than those in the control group(P<0.05).There was no significant difference in the cumulative cardiovascular mortality between the experiment group and the control group(3.9%vs.5.9%,P=0.524).The cumulative HF rehospitalization rate was lower in the experimental group than that of the control group(9.8%vs.23.5%,P=0.042).The cumulative end-point-free survival rate was higher in the experiment group than that of the control group(86.3%vs.70.6%,P=0.037).Conclusion Sacubitril valsartan is safer and more effective than ACEI/ARB in the treatment of AMI patients with HFmrEF,and it is worthy of clinical promotion.
RESUMO
BACKGROUND:Olfactory dysfunction is an early biological marker of various diseases.However,the neuroimaging mechanism by which olfactory dysfunction occurs following cerebral small vessel disease is unclear. OBJECTIVE:To explore the different neuroimaging mechanisms of olfactory function regulation in patients with cerebral small vessel disease and Parkinson's disease,and explore the potential application value of olfactory function assessment in patients with cerebral small vessel disease. METHODS:Neuropsychological and olfactory tests,high-resolution structural magnetic resonance and resting-state functional magnetic resonance data were collected in 80 patients with cerebral small vessel disease,44 healthy controls and 29 patients with Parkinson's disease.DPABI,SPM12 and SPSS were used to analyze and compare the amplitude of low frequency fluctuation,regional homogeneity and functional connectivity values between the cerebral small vessel disease,control and Parkinson's disease groups.Correlations between the significantly altered resting-state functional magnetic resonance imaging measures and olfactory and cognitive scores were evaluated. RESULTS AND CONCLUSION:Compared with the control group,low-frequency fluctuation amplitude of the right dorsolateral superior frontal gyrus and the regional homogeneity of the left wedge leaf were significantly reduced in the cerebral small vessel disease and Parkinson's disease groups.The right dorsolateral superior frontal gyrus and the left cuneiform lobe are the seed points.Compared with the Parkinson's disease group,the functional connectivity values of the right anterior cunei,inferior temporal gyrus,anterior central gyrus and dorsolateral superior frontal gyrus,left posterior central gyrus and inferior temporal gyrus were significantly enhanced in the control and cerebral small vessel disease groups.The left cuneiform lobe was the seed point.Compared with the control group,the functional connectivity of the left lingual gyrus was significantly weakened in the cerebral small vessel disease and Parkinson's disease groups.The functional connectivity values of the left middle temporal gyrus and the right posterior central gyrus were enhanced in the control group compared with the cerebral small vessel disease and Parkinson's disease group,and that was enhanced in the cerebral small vessel disease group compared with the Parkinson's disease group.Correlation analysis showed that the olfactory score and cognitive score were positively correlated in the cerebral small vessel disease group,and the regional homogeneity of the left wedge lobe was negatively correlated with the Montreal Cognitive Assessment Scale score,while the functional connectivity of left wedge lobe-left middle temporal gyrus in the Parkinson's disease group was positively correlated with the olfactory recognition score,and the functional connectivity values of the left wedge lobe-left posterior central gyrus and left wedge lobe-left lingual gyrus were positively correlated with the olfactory identification score and the total olfactory score,respectively.The regulation of olfactory function in patients with cerebral small vessel disease has a different neuroimaging mechanism from that of olfactory dysfunction in patients with Parkinson's disease.The olfactory function of patients with cerebral small vessel disease is related to cognitive function.It is speculated that the olfactory function following cerebral small vessel disease is a secondary change of brain dysfunction,while olfactory dysfunction following Parkinson's disease is directly caused by abnormal function of olfactory-related brain areas.Olfactory function assessment in patients with cerebral small vessel disease has potential application in predicting cognitive function.
RESUMO
Objective:To investigate the correlation between the single nucleotide polymorphism (SNP) of the PLCE1 gene and children with primary nephrotic syndrome (PNS) in Guangxi Zhuang Autonomous Region. Methods:This study was a retrospective study, a case-control study was used to select 155 cases of PNS in Guangxi Zhuang children attending the Affiliated Hospital of Youjiang Medical University for Nationalities from January 2017 to January 2021 (PNS group), and 100 healthy Guangxi Zhuang children who were physically examined during the same period (healthy control group). Genotyping of PLCE1 SNP rs3765524, and rs2274223 were performed using the second-generation gene sequencing technology, and their correlation with the development of PNS was analyzed. Logistic regression analysis was used for correlation analysis, and Chi- square test or Fisher′ s exact probability method was used for comparison between groups. Results:(1)Compared with the healthy control group, PLCE1 rs3765524 was correlated with the risk of PNS in children of PNS group, and the TT genotype may reduce the risk of PNS in the co-dominant model ( OR=0.435, 95% CI: 0.238-0.794, P=0.007). There were no significant differences in the genotype of PLCE1 rs2274223 and the frequency of allele distribution between PNS group and healthy control group (all P>0.05). (2) A strong linkage disequilibrium existed at PLCE1 SNP rs3765524 and rs2274223.(3) There were no significant differences in the frequency of the distribution of haplotypes AC, AT and GT between PNS group and healthy control group (all P>0.05). Conclusions:PLCE1 SNP rs3765524 is correlated with the risk of PNS in children in Guangxi Zhuang Autonomous Region, and the TT genotype may be a protective factor for PNS in children in Guangxi Zhuang Autonomous Region.
RESUMO
Objective:To investigate the clinical manifestations, laboratory tests, diagnosis and treatment of discordant lymphoma (DL).Methods:The clinical data of a patient with EB virus-positive DL admitted to Taizhou People's Hospital in November 2019 were retrospectively analyzed and the related literature was reviewed.Results:The patient underwent a cervical lymph node biopsy pathology examination at onset, and then results suggested angioimmunoblastic T-cell lymphoma (AITL). The patient subsequently developed gastrointestinal bleeding and underwent resection of small bowel lesions, and postoperative pathology suggested diffuse large B-cell lymphoma (DLBCL). The patient was finally diagnosed as DL. The R2-CHOP chemotherapy regimen was given to the patient, but the patient still had recurrent gastrointestinal bleeding and poor general condition. The patient refused chemotherapy and was changed to lenalidomide monotherapy. Finally, the patient died due to multiorgan failure, with an overall survival of 13 months.Conclusions:DL is rarely seen in lymphoma, whereas the combination of AITL and DLBCL is extremely rare. The clinicians need to improve the understanding of this disease to avoid misdiagnosis and missed diagnosis.

Objective:To explore the effect of mindfulness therapy on self burden, hope and sleep of middle-aged bladder cancer patients undergoing bladder sparing chemotherapy.Methods:Sixty patients with bladder cancer treated by intravesical instillation chemotherapy with bladder preservation from January 2018 to December 2019 were selected as the study subjects. They were divided into control group and intervention group according to the sequence of chemotherapy time, with 30 cases in each group. Both groups received routine nursing and rehabilitation training in urology, and mindfulness therapy was added to the intervention group for 6 weeks. Before and 6 weeks after the intervention, the sleeping and mental status of the two groups were compared by the Self-Burden Feeling Scale (SPBS), Herth Hope Scale (HHI) and Insomnia Severity Index Scale (lSI).Results:There was no significant difference in SPBS, HHI and ISI scores between the two groups before intervention ( P > 0.05). After 6 weeks of intervention, SPBS score of patients in the intervention group was 47.00±1.41, and that of the control group was 49.50±0.62.After 6 weeks of intervention, the total score of HHI was 32.61±1.94 in the intervention group and 27.22±2.67 in the control group.After 6 weeks of intervention, ISI score of patients in the intervention group was 19.17± 1.72, and that of the control group was 20.67±2.24. The difference between the two groups was statistically significant ( t values were 6.454, -7.042, 2.097, P < 0.01 or 0.05). Conclusions:Mindfulness therapy can effectively improve insomnia and cancer emotional problems in patients with bladder cancer who underwent bladder preservation and perfusion.
