Objective To investigate the changes of C- reactive protein( CRP ) and homocysteine ( Hcy)in the type 2 diabetes with depression,and its clinical significance and potential mechanism. Methods One hundred and twenty-four cases with type 2 diabetes were divided into the depression group(63 cases)and non-depression group( 61 cases ) according to the Self-Rating Depression Scale and verified by Self-Rating Anxiety Scale. The information including age,sex,education degree,body mass index,course of disease and the number of complications were recorded. The levels of CRP,Hcy,fasting plasma glucose( FPG ),glycosylated hemoglobin(HbA1c)and blood lipid were measured. The depression group was divided into mild,medium and heavy group to compared the changes of Hcy and CRP. Results The levels of Hcy,HbA1c and the number of complications in depression group were 11. 5( 8. 6,15. 6 )μmol/L,( 10. 13 ± 2. 17 )%,and 2( 1,3 ) respectively,higher than that of non-depression group(8. 6(7. 4,11. 2)μmol/L,(9. 33 ± 2. 20)%,1(0,2)), while the education degree of depression group((9. 75 ± 3. 36)years)was lower than that of non-depression group((11. 56 ± 3. 73)years),and the differences were significant( t/Z = -3. 537,0. 952,-2. 339,0. 228 respectively;P ﹤0. 05). The levels of Hcy in mild,medium and heavy depression group were(8. 75(7. 45, 10. 45)μmol/L,12. 2(8. 90,14. 40)μmol/L,19. 50(14. 33,28. 03)μmol/L respectively and the difference was significant(F =25. 963,P =0. 000). No significance difference was found in terms of CRP level(2. 35 (1. 10,4. 92)mg/L,3. 25(1. 11,5. 68)mg/L,2. 32(1. 27,5. 41)mg/L;F=0. 194,P=0. 907). There was significant correlation between depression scores and Hcy( r=0. 615,P=0. 000). Conclusion Type 2 diabetes with depression is associated with the level of blood glucose,education degree and the course of disease. Hcy,not CRP is an independent risk factor of type 2 diabetes with depression.

Objective To investigate the association of serum dehydroepiandrosterone sulfate( DHEA-S) with the cognition in male type 2 diabetes mellitus(T2DM)patients. Methods 99 male patients cared at Tangshan Gongren Hospital and another 97 male healthy controls without T2DM from the medical examination center were recruited. Data on demographic characteristics and clinical parameters were collected, DHEA-S was measured by radioimmunologic assay. Cognitive performance was assessed by the Repeatable Battery for the Assessment of Neuropsychological Status(RBANS). Results (1) Serum DHEA-S levels were lower in male T2DM patients than that of controls[(2. 66 ± 0. 78 vs 4. 02 ± 1. 24) μmol/ L, P<0. 01];(2) Compared with controls, RBANS scores including immediate memory(79. 24 ± 17. 47 vs 86. 25 ± 15. 21, P<0. 01), visuospatial/ constructional(83. 98 ± 17. 98 vs 97. 24 ± 11. 51, P<0. 01), attention(96. 04 ± 14. 65 vs 101. 45 ± 13. 93, P<0. 01), delayed memory (89. 28 ± 11. 74 vs 97. 41 ± 9. 41, P<0. 01), and total scores(85. 85 ± 11. 46 vs 94. 60 ± 10. 91, P<0. 01)were all lower in male T2DM patients;(3) RBANS scores including delayed memory(84. 53 ± 12. 23 vs 93. 94 ± 9. 18, P<0. 01)and total scores(80. 33 ± 10. 91 vs 91. 26 ± 9. 25, P<0. 01)in T2DM patients with low-level DHEA-S(DHEA-S-L)were all lower than those of patients with high-level DHEA-S;(4)Male T2DM patients with cognitive impairment had lower levels of DHEA-S than patients without cognitive impairment(2. 31 ±0. 79 对 2. 90 ±0. 67, P<0. 01);(5) In male T2DM patients, DHEA-S was positively correlated with delayed memory(r = 0. 252, P = 0. 019) and total scores(r=0. 258, P= 0. 016). Conclusion Male T2DM patients are with lower serum DHEA-S levels and worse cognitive performance, and serum DHEA-S was positively correlated with their cognitive performance, suggesting that serum DHEA-S may be involved in the cognitive deficits of male T2DM patients.

Objective:To systematically sort out the research context of home-visiting nurses, and explore research hotspots and development trends in this field, so as to provide reference and ideas for follow-up research.Methods:We retrieved literature on home-visiting nurses included in PubMed from January 1, 2010 to August 1, 2020. The year of publication, journal, country, first author, and high-frequency subject terms were counted. BICOMB and gCLUTO were used to perform cluster analysis and visual analysis of subject terms.Results:A total of 1 223 articles were included, and 35 high-frequency subject terms were extracted. Through cluster analysis, four research hotspots were obtained, namely palliative care and chronic disease management, maternal and child nursing, perinatal health promotion nursing services, home-visiting nurse role function play and nurse-patient relationship, the role of home-visiting nurses in primary health care and in reducing patient hospitalization and readmission.Conclusions:The research results of home-visiting nurses continue to increase, and the topics are increasingly diversified. However, the field of home-visiting nurse research in my country is limited. We can learn from foreign experience and rely on the rapid development of "Internet + Nursing Service" to improve the connotation and quality of home care services.

Objective:To summarize the best evidence for nutrition management of type 2 diabetes mellitus (T2DM) , so as to provide a reference for formulating nutrition management plans.Methods:According to the "6S" evidence model, evidence-based guidelines, expert consensus, and systematic reviews on nutrition management for T2DM were systematically searched and screened in professional group websites, clinical practice guideline websites and databases. The Appraisal of Guidelines for Research and Evaluation (AGREE) Ⅱwas used to assess the methodological quality of the guideline. Quality evaluation of systematic reviews and expert consensus was conducted according to the appraisal system of the Australian Joanna Briggs Institute (JBI) Evidence-based Health Care Center. The recommended items with the same or similar content were synthesized according to the principle of evidence synthesis, and group discussion was carried out on evidence of conflicting conclusions. The recommendations for nutrition management of T2DM suitable for our national conditions were selected.Results:A total of 5 399 domestic and foreign articles were searched, and 19 articles were finally included, including 8 guidelines, 1 expert consensus, and 10 systematic reviews. The quality evaluation results of 1 guideline were grade A, and 7 guidelines were grade B, and the results of systematic review and expert consensus evaluation were both recommended. According to the principle of evidence synthesis, the recommendations were synthesized, including 5 aspects, namely nutrition management methods, nutrition screening and assessment, energy requirements, macronutrient intake, and micronutrient intake, with a total of 29 pieces of best evidence.Conclusions:Evidence on nutrition management of adults with T2DM is extensive but limited. Macronutrients have similar recommendations. However, there is still a lack of high-quality evidence for micronutrients, especially in terms of whether routine micronutrient supplementation is necessary and the specific intake. Extensive practical exploration and scientific research are needed to enrich the relevant evidence in the field of T2DM.

Objective:To investigate the safety and long-term outcomes of fully covered self-expanding metal stent (FCSEMS) placement in patients with benign refractory pancreatic stenosis.Methods:Data of 18 patients with benign refractory pancreatic stenosis who underwent endoscopic treatment with FCSEMS in Nanjing Drum Tower Hospital between March 2013 and July 2020 were collected. The technical success, clinical success, adverse events and long-term outcomes were analyzed.Results:FCSEMS placement was successful in all 18 patients, with technical success rate of 100.0% (18/18). After stenting, the visual analogue scale (VAS) significantly decreased [2.00 (1.75, 3.00) VS 6.00 (5.00, 7.00), Z=-3.572, P<0.001]. The VAS decreased by more than 50% in 15 cases, and the clinical success rate was 83.3% (15/18). Stent-related adverse events included intolerable pain in 3 patients, stented-induced de novo stricture in 2 patients, and distal migration of stent in 2 patients. The stents were successfully removed in all patients after 137.5 (59.0, 417.0) days. There was significant reduction in terms of decreased upstream ductal dilatation after stent removal [9.1 (6.7, 14.1) mm VS 11.0 (7.6, 16.2) mm, Z=10.508, P<0.001]. After stent removal, 10 of the 14 patients maintained the response to pancreatic stenting and 4 recurred during the follow-up of 37-1 246 days. Conclusion:FCSEMS placement appears to be safe and effective in the treatment of benign refractory pancreatic stenosis and can provide persistent improvement in the stricture.

Objective:To systematically review the effects of limited fluid intake on the prognosis of patients with heart failure.Methods:RCTs about the effects of limited fluid intake on the prognosis of patients with heart failure published up to March 31, 2021 were retrieved from PubMed, The Cochrane Library, CINAHL, Embase, Web of Science, CNKI, Wanfang, VIP, and SinoMed. Two independent researchers were employed to extract data and evaluate the quality of included literature. Rev Man 5.3 was used for Meta-analysis, sequential analysis to evaluate the reliability and authenticity of the research results, and the Egger's test for publication bias.Results:A total of 7 articles were included, with a sample size of 867 cases. Meta-analysis showed that the body weight [ MD=-3.04, 95% CI (-4.70, -1.38) , P<0.001], B-type natriuretic peptide [ MD=-249.32, 95% CI (-305.00, -193.63) , P<0.001], blood creatinine [ MD=-22.03, 95% CI (-24.98, -19.09) , P<0.001], readmission rate [ OR=0.30, 95% CI (0.20, 0.45) , P<0.001] of the limited fluid intake group in the chronic phase of heart failure were lower than those in the control group; the body weight [ MD=1.41, 95% CI (-3.73, 6.55) , P=0.59], B-type natriuretic peptide [ MD=64.52, 95% CI (-50.01, 179.06) , P=0.27], serum creatinine [ MD=3.83, 95% CI (-9.69, 17.36) , P=0.58], readmission rate [ OR=1.21, 95% CI (0.65, 2.27) , P=0.55] of the acute fluid intake group were not statistically different from those in the control group. Conclusions:Limiting fluid intake in the chronic phase of heart failure can effectively improve the patients' heart and kidney function and the prognosis of the disease. In the acute phase of heart failure, it may be necessary to combine multiple treatments to keep the patients at the best volume state.
