Chinese Journal of Geriatrics 2021;40(4):475-478
Objective:To investigate clinical effects of a good control of blood sugar during perioperative period on surgical tolerance and postoperative recovery in elderly patients with gastric cancer and diabetes.Methods:A total of 92 elderly patients with gastric cancer and diabetes undergoing surgery in our hospital from August 2018 to March 2020 were randomly divided into a control group(taking conventional perioperative care, n=46)and an observation group(taking conventional perioperative care and good glycemic control, n=46). The changes of perioperative blood glucose level, surgical conditions and postoperative recovery in the two groups were observed and analyzed.Results:Fasting blood glucose level of observation group and control group was[(7.4±1.1)mmol/L vs.(7.9±1.3)mmol/L, t=-1.991, P=0.025]at 1 d before operation, [(7.2±0.9)mmol/L vs.(8.7±1.2)mmol/L, t=-6.782, P=0.000]during operation, and[(6.9±1.5)mmol/L vs.(8.5±1.1)mmol/L, t=-5.834, P=0.000]after operation.Anyway, fasting blood glucose level was lower in the observation group than in the control group.In observation vs control group, time of incision healing[(7.5±1.6)d vs.(9.7±2.2)d, t=-5.485, P=0.000], time to get out of bed[(3.3±0.8)d vs.(4.7±1.3)d, t=-6.221, P=0.000], length of stay in hospital[(10.5±2.7)d vs.(15.1±3.5)d, t=-7.058, P=0.000]were shorter in observation group than in control group.The incidence of postoperative complications was lower in the observation group than in the control group(8.70% vs.26.09%, χ2=4.484, P=0.028). Conclusions:The application of perioperative glycemic control can effectively maintain the perioperative blood glucose at a reasonable and stable level, improve the surgical tolerance and promote the postoperative recovery in elderly patients with gastric cancer and diabetes.And it plays a very positive role in ensuring the safety of surgery

Objective:To summarize our clinical experience in the treatment of aortic root aneurysm by aortic valve sparing root replacement.Methods:From May 2017 to October 2019, a total of 20 patients with aortic root aneurysm underwent aortic valve sparing root replacement by reimplantation method. There were 17 males and 3 females, with an average age of(35.6±15.8) years(12-63 years). There were 11 cases of Marfan syndrome, 5 cases of bicuspid aortic valve, and 1 case of redo operation. The preoperative diameter of ascending aorta was(40.6±9.7)mm, the diameter of aortic sinus was(52.2±9.2)mm, and the diameter of aortic valve ring was(27.1±3.6)mm. There were 10 cases of no or mild regurgitation, 5 cases of moderate regurgitation and 5 cases of severe regurgitation. In the whole group of patients, the root replacement of aortic valve was retained by reimplantation, and the artificial graft were selected as: 26, 28 and 30mm straight vessels, 1, 3 and 6 cases, respectively, 26 and 28mm artificial graft with valsalva sinus, 4 and 6 cases, respectively. During the operation, aortic valve cusp repair was performed in 6 cases, such as plication of the free margin( 4 cases), decalcification(1 case) and raphe release(1 case).Results:None of the patients died in hospital or underwent rethoracotomy for hemostasis. During the operation, the duration of CPB time was(171.0±25.6) minutes and the duration of cross-clamp time was(134.0±23.2) minutes. There were 12 cases of aortic valve regurgitation and 8 cases of mild regurgitation. The mean follow-up was(15.1±9.8) months(4-33 months). During the follow-up period, there were 2 cases with moderate aortic regurgitation no need reoperation, while the rest of the patients had no or mild regurgitation. There are no patients undergoing reoperation. During the follow-up, 1 patient suffered coronary artery embolism in left circumflex artery and recovered after medicine treatment.Conclusion:Reimplantation with aortic valve sparing root replacement is safe and effective in the treatment of aortic root aneurysm, and the early and mid-term follow-up results are satisfactory, which can avoid anticoagulation-related complications and is suitable for young patients.

Objective To explore the changes in expression of Klotho, an aging-suppression protein, and neutrophil gelatinase associated lipocalin ( NGAL) and their relationship with rat mesangial cells ( RMCs) cultured with high glucose in vitro, and to explore the role played by Toll-like receptor-4 (TLR4) / nuclear factor-kB(NF-kB) p65 pathways in this process. Methods Three NGAL-siRNA sequences were designed and synthesized. The effective sequence in subsequent experiments was chosen. RMCs were preincubated with pyrrolidinedithiocarbamate (PDTC)or exogenously added Klotho prior to high glucose treatment. Realtime PCR was used to analyze Klotho, TLR4, NGAL mRNA expressions. Western blot was used to observe Klotho, TLR4,NF-kB p65, NGAL,fibronectin (FN), and connective tissue growth factor ( CTGF) protein expression. ELISA assay was used to detect monocyte chemoattractant protein-1 ( MCP-1) and CXCL5 secretions. Results High glucose suppressed Klotho expression significantly(P<0. 05) and activated TLR4 / NF-kB p65 pathway. Meanwhile,the levels of NGAL,FN,CTGF, MCP-1, and CXCL5 were highly expressed ( P < 0. 01). NGAL gene silencing obviously down-regulated the increased expressions of FN, CTGF, MCP-1, and CXCL5 ( P < 0. 01). After PDTC treatment the overexpression of NGAL protein was markedly lowered(P<0. 01). In addition, Klotho treatment significantly inhibited the activity of TLR4 /NF-kB p65 pathways and down-regulated the expressions of NGAL, FN, CTGF, MCP-1 and CXCL5 stimulated by high glucose(P<0. 01). Conclusion Klotho inhibits the activity of TLR4 / NF-kB p65 pathways and thus inhibits NGAL expression in RMCs cultured with high glucose in vitro. And then it suppresses the expressions of FN, CTGF, MCP-1, and CXCL5. This provides a new basis to illustrate the protection mechanism of the anti-aging protein Klotho in diabetic nephropathy, and may provide new ideas and therapeutic targets for prevention and treatment.
