Objective To analyze the diagnostic value of shear wave elastography (SWE) combined with vascular endothelial growth factor B (VEGF-B) and hemoglobin A1c (HbA1c) in early diabetic peripheral neuropathy (DPN). Methods A total of 100 patients with type 2 diabetes mellitus (T2DM) admitted to Mianyang Central Hospital between October 2020 and October 2023 were selected and divided into a T2DM with DPN group (n=31) and a T2DM without DPN group (n=69) based on the presence or absence of DPN. Additionally, 50 healthy individuals from the same hospital’s health examination center were included as a healthy control group. The basic clinical characteristics, mean elasticity (Emean) values of the left and right median and tibial nerves, serum VEGF-B, and HbA1c levels were compared among the three groups. The diagnostic efficacy of SWE, VEGF-B, and HbA1c for DPN was evaluated using receiver operating characteristic (ROC) curves, and Pearson correlation analysis was performed to assess the relationships between median/tibial nerve Emean and VEGF-B/HbA1c. Results The Emean values of the left and right median nerves, Emean values of the left and right tibial nerves, serum VEGF-B, and HbA1c levels in the T2DM with DPN group were significantly higher than those in the T2DM without DPN group and the healthy control group (P<0.05). The Emean values of the left and right median and tibial nerves, Emean values of the left and right tibial nerves, and HbA1c level in the T2DM without DPN group were significantly higher than those in the healthy control group (P<0.05), while no significant difference was observed in serum VEGF-B level between the T2DM without DPN group and the healthy control group (P>0.05). The area under the ROC curve for the combined diagnosis of DPN using SWE, VEGF-B, and HbA1c was 0.859 [95% confidence interval (0.828, 0.955)]. The sensitivity of the combined diagnosis (93.72%) was significantly higher than that of individual diagnoses (78.82%, 75.39%, and 71.05%, respectively; P<0.05), while the specificity (88.64%) showed no significant difference compared to individual diagnoses (80.18%, 78.96%, and 82.88%, respectively; P>0.05). Positive correlations were observed between median/tibial nerve Emean and VEGF-B/HbA1c levels (r=0.428, 0.395, 0.416, and 0.416, respectively; P<0.05). Conclusions Elevated median/tibial nerve Emean, serum VEGF-B, and HbA1c levels are closely associated with DPN. The combination of SWE, VEGF-B, and HbA1c improves diagnostic sensitivity for DPN, demonstrating significant clinical value.
目的:探讨血清铁蛋白（SF）、红细胞参数（红细胞计数RBC、血红蛋白HGB、红细胞体积MCV）及炎症标志物（白细胞计数WBC、纤维蛋白原FIG、血沉ESR）与老年代谢综合征（MS）的关系。方法:148例老年人,依据MS组分数量多少分为MS0（无MS组分）、MS1～2（有1～2个MS组分）和MS3～5（有3～5个MS组分）三组。测定三组的血SF、空腹血糖FPG、甘油三酯TG、高密度脂蛋白胆固醇HDL-C、RBC、HGB、MCV、WBC、FIG及ESR水平,并进行分析。结果:老年女性及非吸烟老年男性MS组SF、RBC、HGB、WBC及ESR均较MS0组高。老年女性的SF、WBC与腰围,SF、RBC、HGB、WBC与MS组分数量,SF与RBC,均呈正相关。老年非吸烟男性的WBC与TG,HGB与MS组分数量,MCV与BMI及腰围,FIG与BMI,呈正相关。老年人HGB与DBG、TG呈正相关；与HDL-C呈负相关。结论:SF水平与MS发展相关,MS组分数量增加与聚集、超重与肥胖,可能促进体内感染状态。有MS的老年男女,常呈现低度感染状态,但同时又有一定的铁储备及相对稳定的造血机能；无MS的老年男女造血功能倾向减退。老年男性吸烟者较非吸烟者易呈现感染状态,并具有较低的铁储备。
ObjectiveTo investigate the effect of 24-week intradialytic progressive resistance exercise on hemoglobin and iron metabolism in maintenance hemodialysis (MHD) patients.MethodsFrom April to May 2019, 62 MHD patients were enrolled and randomly assigned into exercise group (n=31) and control group (n=31). Both groups of patients received regular routine hemodialysis, on that basis, patients in the exercise group completed intradialytic resistance exercise three times per week for 24 weeks. Each exercise included 8-10 muscle groups (grasping the grip ring with both hands, flexion and extension of the elbows and shoulders on the non-vascular side and lower limbs with sandbag), 3 sets of 15 repetitions with a rest of 1-2 min between 2 sets. Exercise began with a low load, the sandbag weight was gradually increased, and the Borg score was aimed to be 11-13 points after exercise. Hemoglobin, serum ferritin, transferrin saturation, serum creatinine, high-sensitivity C-reactive protein, urea clearance index, recombinant human erythropoietin (rHuEPO) dosage at baseline and after 24 weeks, as well as the cumulative iron supplement dose and hemoglobin variation of the two groups during the study period were evaluated.ResultsThere were 20 patients in the exercise group and 30 ones in the control group who completed the study. After 24 weeks of progressive resistance exercise, the medium (lower quartile, upper quartile) of the amount of rHuEPO in the exercise group decreased from 6 000 (6 000, 9 000) U/week to 6 000 (4 500, 7 125) U/week (Z=−2.599, P=0.009), while that in the control group had no statistically significant difference (Z=−1.340, P=0.180); there was no statistically difference in hemoglobin, hemoglobin coefficient of variation, serum ferritin, transferrin saturation, or 24-week cumulative iron supplementation between the two groups.ConclusionIntradialytic progressive resistance exercise can reduce the amount of rHuEPO in MHD patients, which is benefitial to optimizing the management of hemoglobin.
Objective To investigate the relationship between preoperative hemoglobin, albumin, lymphocyte and platelet (HALP) score, and clinicopathologic features of colon cancer, and to analyze the predictive value of HALP score for postoperative liver metastasis. Methods The clinical data of 163 patients with colon cancer admitted to the 909th Hospital of Joint Logistic Support Force (Dongnan Hospital of Xiamen University) from January 2018 to December 2019 were retrospectively analyzed. According to the occurrence of postoperative liver metastasis, the patients were divided into metastatic group (n=35) and non-metastatic group (n=128). The correlation between preoperative HAPL score and clinicopathologic features of colon cancer was analyzed. The predictive value of HALP score for postoperative liver metastasis of colon cancer was analyzed by using receiver operating characteristic (ROC) curve. The risk factors of liver metastasis after colon cancer surgery were analyzed by using univariate and multivariate logistic analysis. Kaplan-Meier risk curve was drawn, and log-rank test was used to analyze the predictive value of different HALP score for postoperative liver metastasis. Results HALP score were decreased in patients with maximum tumor diameter ≥5 cm, preoperative carcinoembryonic antigen (CEA) ≥5 μg/L, serous membrane and extrasserous infiltration, lymph node metastasis and vascular invasion, and the difference was statistically significant (P<0.05). Multivariate logistic regression analysis showed that HALP score [OR=1.467, 95%CI (1.253, 1.718), P<0.001], maximum tumor diameter [OR=3.476, 95%CI (1.475, 5.358), P=0.013], preoperative CEA level [OR= 6.197, 95%CI (2.436, 6.248), P=0.005], and lymph node metastasis [OR=2.593, 95%CI (1.667, 6.759) , P=0.003] were risk factors for postoperative liver metastasis of colon cancer. ROC curve analysis showed that the area under the curve of HALP score for predicting liver metastasis after colon cancer surgery was 0.908 (0.841, 0.974), the maximum value of the Youden index was 0.738, the optimal cut-off value of the HALP score was 35.5, the sensitivity was 0.852, the specificity was 0.886. Kaplan-Meier risk curve showed that the risk of early postoperative liver metastasis in the low HALP score group was higher than that in the high HALP score group (χ2=8.126, P=0.004). Conclusion Low HALP score in patients with colon cancer is associated with adverse prognosisi related pathological features, and is an influential factor for postoperative liver metastasis of colon cancer, and has predictive value for patients with postoperative liver metastasis of colon cancer.
Objectives To systematically analyze the effect of high-intensity and low-intensity resistance training on glycosylated hemoglobin (HbA1c) in elderly patients with type 2 diabetes. Methods PubMed, EBSCO, Cochrane Library, Web of science, Wanfang, Chinese National Knowledge Infrastructure and Chongqing VIP were searched to collect randomized controlled trials of resistance training intervention in elderly patients with type 2 diabetes. The search time limit was from the establishment of the database to August 28, 2021, and the RevMan 5.3 and Stata 15.0 software were used for meta-analysis. Results A total of 415 patients in 8 articles were included in this study. A subgroup analysis based on control measures showed that compared with the resistance training group, the HbA1c level effect value of the non- training group was weighted mean difference (WMD) = −0.54% [95% confidence interval (CI) (−1.06%, −0.03%), P=0.04)], the HbA1c level effect value of the flexibility training group was WMD=−0.47% [95%CI (−1.05%, 0.12%), P=0.12], the HbA1c level effect value of the aerobic training group was WMD=−0.10% [95%CI (−0.71%, 0.51%), P=0.75]. Subgroup analysis of resistance strength showed that compared with the flexibility or non-resistance training group, both high-intensity [WMD=−0.99%, 95%CI (−1.16%, −0.81%), P<0.00001] and low- and medium-intensity resistance training [WMD=−0.29%, 95%CI (−0.58%, −0.01%), P=0.05] can reduce HbA1c. Compared with the high-intensity resistance training, the HbA1c level effect value of the low- and medium-intensity resistance training was WMD=0.03% [95%CI (−0.33%, 0.39%), P=0.88]. Compared with the low- and medium-intensity resistance training, the HbA1c level effect value of the low- and medium-intensity aerobic training was WMD=−0.10% [95%CI (−0.71%, 0.51%), P=0.75]. Among all the included studies, only the high-intensity resistance training group reported multiple adverse events.ConclusionsCurrent evidence suggests that elderly patients with type 2 diabetes are more suitable to choose low-to-medium-intensity resistance training to control HbA1c. It is recommended that elderly patients with type 2 diabetes take 60% to 75% of the maximum muscle strength of medium-intensity resistance training.
ObjectiveTo observe and analyze the correlation between erythrocyte count and hemoglobin level in early life and retinopathy of prematurity (ROP). MethodsA clinical retrospective study. From January 2020 to December 2022, a total of 303 premature infants, who underwent fundus screening in Children's Hospital of Henan Province were included. There were 219 males and 84 females, with the average gestational age of (30.36±1.52) weeks and the average birth weight of (1 368.43±171.37) g. Early life was defined as 14 days after birth. According to the screening results, patients were divided into ROP group and no ROP group (control group). The results of red blood cell count, hematocrit and hemoglobin concentration of the two groups were compared and observed on the 3rd, 7th and 14th day after birth. The measurement data were compared by t-test, and the count data were compared by χ2 test. The risk factors of ROP were analyzed by logistic regression. The correlation between red blood cell count as well as hemoglobin concentration in early life and ROP was analyzed by receiver operating characteristics (ROC) curve. ResultsAmong the 303 premature infants screened, a total of 101 preterm infants were included in the ROP group, with the average gestational age of (30.39±1.48) weeks. And a total of 202 preterm infants were included in the control group, with the average gestational age of (30.35±1.55) weeks. There was no significant difference between the two groups in sex composition ratio (χ2=0.296) and gestational age (t=0.251) (P＞0.05). There were significant differences in birth weight (t=－2.024), blood transfusion times (U=－4.957), invasive mechanical ventilation duration (U=－2.215) and continuous positive airway pressure ventilation time (U=－5.224) between the two groups (P＜0.05). The incidence of periventricular leukomalacia (χ2=5.069), bronchopulmonary dysplasia (χ2=9.794) and sepsis (χ2=8.041) were significantly different (P＜0.05). The average hemoglobin level of patients in the ROP group on the 3rd, 7th and 14th day after birth were lower than those in the control group (t=－3.813, －2.753, －2.847; P＜0.05). Logistic regression analysis showed that low frequency of blood transfusion [odds ratio (OR)=1.241, 95% confidence interval (CI) 1.016-1.517] and short duration of continuous positive airway pressure (OR=1.128, 95%CI 1.031-1.234) were protective factors for ROP. The ROC curve analysis indicated that the abnormal threshold values of hematocrit and hemoglobin were the highest on the 14th day after birth, which were 115.5 g/L and 36.25% respectively. The sensitivities were 88.1% and 83.2%, respectively. ConclusionRed blood cell count and hemoglobin level in early life of preterm infants may have a certain correlation with the occurrence and development of ROP.
ObjectiveTo study the correlation of postoperative cognitive dysfunction (POCD) with type-2 diabetes and glycosylated hemoglobin (HbA1c) levels in elderly patients. MethodsA total of 140 elderly patients who were going to undergo non-cardiothoracic surgery in our hospital between January 2011 and February 2013 were included in this study.ASA classification was between I and Ⅲ.There were 78 males and 62 females,aged between 65 and 86 years old.Group A had 70 patients with diabetes,while group B had another 70 corresponding patients without diabetes.One day before surgery and a week after surgery,Mini-mental State Examination (MMSE) and Montreal Cognitive Functioning Scale (MoCA) were used to test patients'cognitive function,and the incidence of POCD was compared between the two groups.Group A patients,according to HbA1c levels,were divided into group AH (HbA1c>7.5%) and group AL (HbA1c<7.5%).And we compared the relationship between group AL and group B,and the relationship between group AH and group B. ResultsThe incidence of POCD in group A was significantly higher than that in group B (P<0.05).Group AH had a significantly higher incidence of POCD than group AL (P<0.05).No significant difference was found in fasting plasma glucose among the groups. ConclusionElderly diabetic patients with poor glycemic control is a risk factor for POCD occurrence,but fasting glucose as a predictor of POCD is not as good as HbA1C.
ObjectiveTo explore the association between glycosylated hemoglobin level and poor prognosis in acute ischemic stroke (AIS) patients treated with intravenous thrombolysis.MethodsThe AIS patients treated with recombinant tissue-type plasminogen activator who were hospitalized in the Department of Neurology of the First Affiliated Hospital of Henan University of Science and Technology from September to December 2020 were retrospectively included. According to different levels of glycosylated hemoglobin, they were divided into pre-diabetic group (5.7%≤glycated hemoglobin≤6.4%), diabetic group (previously diabetic or glycosylated hemoglobin≥6.5%), and non-diabetic group (glycated hemoglobin <5.7%). The relevant information of the patients was collected, and a telephone follow-up was conducted 90 days after discharge. According to the modified Rankin Scale (mRS) score, the patients were divided into the good prognosis group (mRS score≤2) and the poor prognosis group (mRS score>2). Logistic regression analysis was used to determine the risk factors for the poor prognosis of intravenous thrombolysis in patients with AIS.ResultEventually 101 patients were included, including 44 in the non-diabetic group, 24 in the pre-diabetic group, and 33 in the diabetic group. And 64 patients were in the good prognosis group and 37 patients were in the poor prognosis group. Regression analysis results showed that diabetes was associated with poor prognosis 3 months after intravenous thrombolysis in patients with AIS [odds ratio=6.518, 95% confidence interval (1.568, 27.096), P=0.010]; and the higher the National Institutesof Health Stroke Scale score at admission was, the higher the risk of poor prognosis would be [odds ratio=1.421, 95% confidence interval (1.231, 1.640), P<0.001].ConclusionIn AIS patients who received intravenous thrombolysis, diabetes is associated with poor prognosis after 3 months.
