Analysis of Blood Lipids, Blood Glucose, Blood Uric Acid, and Blood Routine Test Results in Retired Employees of a Unit in the Civil Aviation System

Objective:To investigate and analyze the annual physical examination results of retired employees from a unit in the civil aviation system,focusing on blood lipids,blood glucose,blood uric acid,and blood routine results.The study aims to provide relevant references for formulating reasonable disease management measures for preventing and controlling hyperlipidemia,hyperuricemia,and other conditions in retired employees.Methods:The examination results of 231 participants were collected and analyzed.The participants were divided into four groups based on age:middle-aged group,young-old group,middle-old group,and old-old group.The blood test results were compared across these groups,and an assessment of atherosclerotic cardiovascular disease(ASCVD)risk levels was completed in conjunction with medical history.Blood test results were also compared by gender.Results:There were no significant statistical differences in blood test results when grouped by age.However,the prevalence of hyperuricemia was higher in males than in females,while the prevalence of hypercholesterolemia was higher in females than in males.The LDL-C target achievement rate was lower in the moderate-and-high-risk group as well as the very high-risk group as defined by ASCVD risk levels.Conclusion:Management of hyperuricemia and hyperlipidemia in retired employees(elderly patients)should be strengthened to reduce the risk of ASCVD events and alleviate the potential medical burden associated with disease progression.

Effect of dates on blood glucose and lipid profile among patients with type 2 diabetes

Poor fruit and vegetable consumption is one of the 10 major risk factors for mortality.There is a misconception regarding the consumption of dates among patients with diabetes.This manuscript assessed the effects of date consumption on fasting and postprandial blood glucose,glycated hemoglobin,total cholesterol,triglycerides,low-density lipoproteins,high-density lipoproteins,and microbial markers.Four literature databases were searched for relevant articles.Of the 595 studies retrieved,24 assessed the effects of dates on glycemic control and lipids.Overall,the evidence suggests that dates have a lowering effect on blood glucose.Dates reduce total cholesterol and triglyceride levels and increase high-density lipoprotein levels.Dates also promote the abundance of beneficial gut microbiota.Therefore,patients with diabetes and dyslipidemia can consume dates to reduce their blood glucose,cholesterol,and triglycerides.

Influence of blood glucose fluctuations on chemotherapy efficacy and safety in type 2 diabetes mellitus patients complicated with lung carcinoma

BACKGROUND Patients with type 2 diabetes mellitus(T2DM)have large fluctuations in blood glucose(BG),abnormal metabolic function and low immunity to varying degrees,which increases the risk of malignant tumor diseases and affects the efficacy of tumor chemotherapy.Controlling hyperglycemia may have important therapeutic implications for cancer patients.AIM To clarify the influence of BG fluctuations on chemotherapy efficacy and safety in T2DM patients complicated with lung carcinoma(LC).METHODS The clinical data of 60 T2DM+LC patients who presented to the First Affiliated Hospital of Ningbo University between January 2019 and January 2021 were retrospectively analyzed.All patients underwent chemotherapy and were grouped as a control group(CG;normal BG fluctuation with a mean fluctuation<3.9 mmol/L)and an observation group(OG;high BG fluctuation with a mean fluctuation≥3.9 mmol/L)based on their BG fluctuations,with 30 cases each.BGrelated indices,tumor markers,serum inflammatory cytokines and adverse reactions were comparatively analyzed.Pearson correlation analysis was performed to analyze the correlation between BG fluctuations and tumor markers.RESULTS The fasting blood glucose and 2-hour postprandial blood glucose levels in the OG were notably elevated compared with those in the CG,together with markedly higher mean amplitude of glycemic excursions(MAGE),mean of daily differences,largest amplitude of glycemic excursions and standard deviation of blood glucose(P<0.05).In addition,the OG exhibited evidently higher levels of carbohydrate antigen 19-9,carbohydrate antigen 125,carcinoembryonic antigen,neuron-specific enolase,cytokeratin 19,tumor necrosis factor-α,interleukin-6,and highsensitivity C-reactive protein than the CG(P<0.05).Pearson analysis revealed a positive association of MAGE with serum tumor markers.The incidence of adverse reactions was significantly higher in the OG than in the CG(P<0.05).CONCLUSION The greater the BG fluctuation in LC patients after chemotherapy,the more unfavorable the therapeutic effect of chemotherapy;the higher the level of tumor markers and inflammatory cytokines,the more adverse reactions the patient experiences.

Retinal microcirculation changes in prediabetic patients with shortterm increased blood glucose using optical coherence tomography angiography

BACKGROUND Retinal microcirculation alterations are early indicators of diabetic microvascular complications.Optical coherence tomography angiography(OCTA)is a noninvasive method to assess these changes.This study analyzes changes in retinal microcirculation in prediabetic patients during short-term increases in blood glucose using OCTA.AIM To investigate the changes in retinal microcirculation in prediabetic patients experiencing short-term increases in blood glucose levels using OCTA.METHODS Fifty volunteers were divided into three groups:Group 1[impaired fasting glucose(IFG)or impaired glucose tolerance(IGT)],Group 2(both IFG and IGT),and a control group.Retinal microcirculation parameters,including vessel density(VD),perfusion density(PD),and foveal avascular zone(FAZ)metrics,were measured using OCTA.Correlations between these parameters and blood glucose levels were analyzed in both the fasting and postprandial states.RESULTS One hour after glucose intake,the central VD(P=0.023),central PD(P=0.026),and parafoveal PD(P<0.001)were significantly greater in the control group than in the fasting group.In Group 1,parafoveal PD(P<0.001)and FAZ circularity(P=0.023)also increased one hour after glucose intake.However,no significant changes were observed in the retinal microcirculation parameters of Group 2 before or after glucose intake(P>0.05).Compared with the control group,Group 1 had a larger FAZ area(P=0.032)and perimeter(P=0.018),whereas Group 2 had no significant differences in retinal microcirculation parameters compared with the control group(P>0.05).Compared with Group 1,Group 2 had greater central VD(P=0.013)and PD(P=0.008)and a smaller FAZ area(P=0.012)and perimeter(P=0.010).One hour after glucose intake,Group 1 had a larger FAZ area(P=0.044)and perimeter(P=0.038)than did the control group,whereas Group 2 showed no significant differences in retinal microcirculation parameters compared with the control group(P>0.05).Group 2 had greater central VD(P=0.042)and PD(P=0.022)and a smaller FAZ area(P=0.015)and perimeter(P=0.016)than Group 1.At fasting,central PD was significantly positively correlated with blood glucose levels(P=0.044),whereas no significant correlations were found between blood glucose levels and OCTA parameters one hour after glucose intake.CONCLUSION A short-term increase in blood glucose has a more pronounced effect on retinal microcirculation in prediabetic patients with either IFG or IGT.

A Study on Near-Infrared Non-Invasive Blood Glucose Concentration Regression Prediction Based on PSO-MKL-SVR

To improve the accuracy of predicting non-invasive blood glucose concentration in the near-infrared spectrum, we utilized the Particle Swarm Optimization (PSO) algorithm to optimize hyperparameters for the Multi-Kernel Learning Support Vector Machine (MKL-SVR). With these optimized hyperparameters, we established a non-invasive blood glucose regression model, referred to as the PSO-MKL-SVR model. Subsequently, we conducted a comparative analysis between the PSO-MKL-SVR model and the PSO-SVR model. In a dataset comprising ten volunteers, the PSO-MKL-SVR model exhibited significant precision improvements, including a 16.03% reduction in Mean Square Error and a 0.29% increase in the Squared Correlation Coefficient. Moreover, there was a 0.14% higher probability of the Clark’s Error Grid Analysis falling within Zone A. Additionally, the PSO-MKL-SVR model demonstrated a faster operational speed compared to the PSO-SVR model.

Noninvasive Blood Glucose Measurement Based on NIR Spectrums and Double ANN Analysis

This paper presents a new noninvasive blood glucose monitoring method based on four near infrared spectrums and double artificial neural network analysis. We choose four near infrared wavelengths, 820 nm, 875 nm, 945 nm, 1050 nm, as transmission spectrums, and capture four fingers transmission PPG signals simultaneously. The wavelet transform algorithm is used to remove baseline drift, smooth signals and extract eight eigenvalues of each PPG signal. The eigenvalues are the input parameters of double artificial neural network analysis model. Double artificial neural network regression combines the classification recognition algorithm with prediction algorithm to improve the accuracy of measurement. Experiments show that the root mean square error of the prediction is between 0.97 mg/dL - 6.69 mg/dL, the average of root mean square error is 3.80 mg/dL.

Investigation and Analysis on the Management Standard of Blood Glucose Monitoring for Clinical Nurses in Nyingchi Region of Tibet

Background: In participating in the medical support work in the Nyingchi area of Tibet, the author found that the medical education resources in this area are scarce, and the clinical nurses in this area have relatively insufficient knowledge about blood glucose monitoring and management. Accurately understanding the knowledge-attitude/belief-practice (KAP) level of nurses in Nyingchi area on blood glucose management is of great significance to the development of blood glucose monitoring management guidance for nurses in this area. Therefore, this study investigated the current status of the management of blood glucose monitoring management standards for clinical nurses in Nyingchi, Tibet. Objective: To investigate and analyze the current situation of clinical nurses in Nyingchi region of Tibet to grasp the regulation of blood glucose monitoring and guide the implementation of the norm of blood glucose monitoring for clinical nurses. Methods: The research survey was carried out from March to April 2020. Random sampling method was used to select 134 clinical in-service nurses in Nyingchii, Tibet. The self-designed knowledge-attitude/belief-practice survey questionnaire for clinical nurses’ blood glucose monitoring and management in Tibet was used. Nurses’ blood glucose monitoring management “KAP” scores and related influencing factors are analyzed. Results: Blood sugar monitoring and management knowledge score is (36.78 ± 6.80), attitude dimension is (42.48 ± 6.42), practice dimension is (61.87 ± 10.24) and total score is (304.73 ± 36.24). The nurse’s department and whether to participate in diabetes training are the main influencing factors of the blood glucose monitoring management norms, knowledge and behavior (both P < 0.05). Conclusion: The standard knowledge of blood glucose monitoring and management of clinical nurses in Nyingchi region of Tibet is at the middle level, positive attitude and unsatisfactory behavior. Nursing managers should conduct standardized training for clinical nurses in blood glucose monitoring, develop the training mode of diabetes specialty nursing talents in Nyingchi area, and construct a complete management system of diabetes specialty nursing.

Efficacy of blood glucose self-monitoring on glycemic control in patients with non-insulin-treated type 2 diabetes: A meta-analysis

Objective:To evaluate the efficacy of blood glucose self-monitoring on glycemic control in patients with non-insulin-treated type 2 diabetes by performing a meta-analysis.Methods:Randomized controlled trials(RCTs)of the efficacy of blood glucose selfmonitoring were collected from the PubMed,EMBASE,Cochrane Library,CNKI,and VIP databases.Data were analyzed by RevMan 5.1 software.Results:Seven RCTs were included in this meta-analysis.The results indicated that blood glucose self-monitoring significantly reduced the glycated hemoglobin(HbA1c)level by 0.41%.Subgroup analysis showed that while implementation of a diabetes management regimen based on the blood glucose self-monitoring results effectively reduced the HbA1c level by 0.42%,no significant improvement in HbA1c level control was observed with the implementation of blood glucose self-monitoring alone.Conclusion:Blood glucose self-monitoring combined with diabetes management effectively improves glycemic control in patients with non-insulin-treated type 2 diabetes.

Analysis on the Correlation between Fasting Blood-glucose and Gestational Diabetes Mellitus

Objective： The correlation between the fasting blood-glucose （FBG） in early pregnancy and the gestational diabetes mellitus （GDM） was studied. Methods： The clinical data of 300 pregnant women receiving a treatment from Yongqing Hospital of Traditional Chinese Medicine and Langfang Health Vocational College from September 2012 to September 2013 was chosen; these cases were divided into group 6.9-6.0 mmol/L （35 cases）, group 5.9~5.0 mmol/L （58 cases）, group 4.9~4.5 mmol/L （120 cases）, and group 4.4~4.0mmol/L （108 cases） according to the range of the normal FBG. The proportional differences among the pregnant women diagnosed with GDM in different groups during the late pregnancy as well as the maternal and fetal prognosis were compared. Results： The proportion of the pregnant women diagnosed with GDM in group 6.9-6.0 mmol/L and group 5.9-5.0 mmol/L during the middle-late pregnancy was significantly higher than that of group 4.9-4.5 mmol/L and group 4.4-4.0mmol/L; there was no significant proportional difference among the pregnant women diagnosed with GDM in group 6.9~6.0 mmol/L and group 5.9-5.0 mmol/L during the middle-late pregnancy; there was no significant proportional difference among the pregnant women diagnosed with GDM in group 4.9-4.5 mmol/L and group 4.4-4.0mmol/L during the middle-late pregnancy. Conclusion： The risk of the pregnant women with FBG is higher than that of the normal pregnant women in suffering GDM during the early pregnancy, so attention should be paid to early blood glucose test and the blood glucose level should be positively controlled once they are defmitely diagnosed with GDM, and then the perinatal and maternal survival quality can be improved.

Meta-analysis about Western Medicine combined with activating blood drugs on modulating blood glucose and lipids in diabetic patients

OBJECTIVE： To assess the effect of activating blood drugs （AB drugs） on blood glucose and lipid levels of diabetic patients METHODS： Systematic searches were conducted on 6 electronic databases and the search time was cut off in May 2016. Randomized controlled trials （RCTs） were included if they investigated diabetic patients who received Western medicine combined withAB drugs in the experimental groups and solitary usage of corresponding Western medicine or placebo in the control groups. 6 outcome measures, which were considered as inclusion, were changes in fasting blood glucose （FBG）, glycosylated haemoglobin A1 c （HbA 1 c）, total triglyceride （TG）, total cholesterol （TC）, low density lipoprotein cholesterol （LDL-c） and high density lipoprotein cholesterol （HDL-c）. The literature quality was assessed by Cochrane score for risk of bias in Review Manager 5.2, as well as meta-analysis was performed. RESULTS： 7 RCTs comprising 999 patients met all inclusion criteria. Meta-analysis showed beneficial effects of Western medicine combined with AB drugs on modulating FBG, TC, LDL-c and HDL-c compared with Western medicine or placebo （P〈0.05）, while no difference was observed in HbAlc, and TG （P〉0.05）. To some extent, the therapeutic effects of Western medicine combined with AB drugs were better than that of solitary usage of Western medicine or placebo. Besides, AB drugs were safe and reliable with little toxic and side-effects. CONCLUSIONS： The meta-analysis suggests beneficial effects of Western medicine combined with AB drugs on modulating blood glucose and lipids in diabetic patients.

Blood gas analysis as a surrogate for microhemodynamic monitoring in sepsis

BACKGROUND:Emergency patients with sepsis or septic shock are at high risk of death.Despite increasing attention to microhemodynamics,the clinical use of advanced microcirculatory assessment is limited due to its shortcomings.Since blood gas analysis is a widely used technique reflecting global oxygen supply and consumption,it may serve as a surrogate for microcirculation monitoring in septic treatment.METHODS:We performed a search using PubMed,Web of Science,and Google scholar.The studies and reviews that were most relevant to septic microcirculatory dysfunctions and blood gas parameters were identified and included.RESULTS:Based on the pathophysiology of oxygen metabolism,the included articles provided a general overview of employing blood gas analysis and its derived set of indicators for microhemodynamic monitoring in septic care.Notwithstanding flaws,several parameters are linked to changes in the microcirculation.A comprehensive interpretation of blood gas parameters can be used in order to achieve hemodynamic optimization in septic patients.CONCLUSION:Blood gas analysis in combination with clinical performance is a reliable alternative for microcirculatory assessments.A deep understanding of oxygen metabolism in septic settings may help emergency physicians to better use blood gas analysis in the evaluation and treatment of sepsis and septic shock.

Investigation and analysis of negative emotion in patients with diabetic retinopathy after vitrectomy

BACKGROUND As the incidence of diabetes continues to increase,the number of patients with diabetic retinopathy(DR)also increases each year.After undergoing vitrectomy for DR,patients often experience negative emotional problems that negatively affect their recovery.AIM To investigate negative feelings in patients with DR after vitrectomy and to explore related influencing factors.METHODS A total of 146 individuals with DR who were accepted for treatment at The Third People’s Hospital of Changzhou from May 2021 to April 2023 were recruited to participate in this study.All patients underwent vitrectomy.The self-rating anxiety scale(SAS)and self-rating depression scale(SDS)were used to assess the degree of anxiety and depression 2-3 days after the operation.The participants were divided into a healthy control group and a negative emotion group.The patients’general demographic characteristics and blood glucose levels were collected.Logistic regression analysis was used to analyze the factors influencing negative feelings post-operation.Pearson’s correlation coefficient was used to analyze the association between SAS scores,SDS scores,and blood glucose levels.RESULTS The control group included 85 participants.The negative emotion group comprised 40 participants with anxiety,13 with depression,and eight with both.Logistic regression showed that being female(OR=3.090,95%CI:1.217-7.847),a family per capita monthly income of<5000 yuan(OR=0.337,95%CI:0.165-0.668),and a longer duration of diabetes(OR=2.068,95%CI:1.817-3.744)were risk factors for negative emotions in patients with DR after vitrectomy(P<0.05).The concentrations of fasting plasma glucose(FPG),2-hour postprandial glucose(2hPG),and glycated hemoglobin(HbA1c)in the negative emotion group exceeded those in the control group(P<0.05).SAS scores were positively associated with FPG(r=0.422),2hPG(r=0.334),and HbA1c(r=0.362;P<0.05).SDS scores were positively correlated with FPG(r=0.218)and 2hPG(r=0.218;P<0.05).CONCLUSION Sex,income level,and duration of diabetes were factors that influenced negative emotions post-vitrectomy.Negative emotions were positively correlated with blood glucose levels,which can be used to develop intervention strategies.

Lowering fasting blood glucose with non-dialyzable material of cranberry extract is dependent on host genetic background,sex and diet

Background:Type 2 diabetes(T2D)is a polygenic metabolic disease,character-ized by high fasting blood glucose(FBG).The ability of cranberry(CRN)fruit to regulate glycemia in T2D patients is well known.Here,a cohort of 13 lines of the genetically diverse Collaborative Cross(CC)mouse model was assessed for the effect of non-dialyzable material(NDM)of cranberry extract in lowering fasting blood glucose.Methods:Eight-week-old mice were maintained on either a standard chow diet(con-trol group)or a high-fat diet(HFD)for 12 weeks,followed by injections of intraperi-toneal(IP)NDM(50 mg/kg)per mouse,three times a week for the next 6 weeks.Absolute FBG(mg/dl)was measured bi-weekly and percentage changes in FBG(%FBG)between weeks 0 and 12 were calculated.Results:Statistical analysis showed a significant decrease in FBG between weeks 0 and 12 in male and female mice maintained on CHD.However,a non-significant in-crease in FBG values was observed in male and female mice maintained on HFD dur-ing the same period.Following administration of NDM during the following 6 weeks,the results show a variation in significant levels of FBG lowering between lines,male and female mice and under the different diets.Conclusion:The results suggest that the efficacy of NDM treatment in lowering FGB depends on host genetic background(pharmacogenetics),sex of the mouse(phar-macosex),and diet(pharmacodiet).All these results support the need for follow-up research to better understand and implement a personalized medicine approach/uti-lization of NDM for reducing FBG.

What,why and how to monitor blood glucose in critically ill patients

Critically ill patients are prone to high glycemic variations irrespective of their diabetes status.This mandates frequent blood glucose(BG)monitoring and regulation of insulin therapy.Even though the most commonly employed capillary BG monitoring is convenient and rapid,it is inaccurate and prone to high bias,overestimating BG levels in critically ill patients.The targets for BG levels have also varied in the past few years ranging from tight glucose control to a more liberal approach.Each of these has its own fallacies,while tight control increases risk of hypoglycemia,liberal BG targets make the patients prone to hyperglycemia.Moreover,the recent evidence suggests that BG indices,such as glycemic variability and time in target range,may also affect patient outcomes.In this review,we highlight the nuances associated with BG monitoring,including the various indices required to be monitored,BG targets and recent advances in BG monitoring in critically ill patients.

Altered Levels of Blood Glucose and Serum Lipids in Sudanese Patients with Ovarian Cancer

Background: The etiology of ovarian cancer is not well-understood;numerous metabolomics profiling, epidemiological, and hospital-based case control studies have associated abnormal levels of blood glucose and serum lipids with the risk and the prognosis of various types of cancers including ovarian cancer. The association between the risk of the incidence of ovarian cancer and the alterations in the levels of blood glucose and serum lipids is not well defined. Objective: In this study we aimed to compare the levels of blood glucose, triacylglycerols, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol in patients with different stages of ovarian cancer and healthy controls to determine how they relate to the risk and prognosis of ovarian cancer. Methodology: In a case-control cross sectional study, we enrolled ninety-nine Sudanese women, diagnosed with ovarian cancer but had not received any kind of treatment as the study group, and a control group of forty-one age-matched, apparently healthy women. The patients were classified according to the International Federation of Obstetricians and Gynecologists staging system into two groups: early stages (stage I & II) and late stages (stages III & IV). Blood glucose and serum lipids;triacylglycerols, total cholesterol, low-density lipoprotein cholesterol and high-density lipoprotein cholesterol were determined by enzymatic colorimetric methods using commercially available analytical kits. The IBM SPSS version 20 software was used for statistical analysis. A Mann-Whitney U test was used for comparison of the median concentrations of blood glucose, triacylglycerols, total cholesterol, low-density lipoprotein cholesterol and high-density lipoprotein cholesterol in the study groups. Logistic regression model was used to estimate the relative risk of ovarian cancer in relation to levels of blood glucose and serum lipids. P value of 0.05 was considered significant. Results: Our data indicated significantly higher levels of blood glucose (p < 0.001), triacylglycerols (p = 0.002), and low-density lipoprotein cholesterol (p < 0.001), and lower levels of high-density lipoprotein cholesterol (p = 0.023), in ovarian cancer patients compared to the control subjects. No significant difference was found in the levels of blood glucose or any of the serum lipids between patients in the early stages (stage I & II) and those in late stages (stage III & IV) of ovarian cancer. The logistic regression analysis indicated significant association between the elevated levels of the blood glucose, triacylglycerols and low-density lipoprotein cholesterol and the risk of the ovarian cancer. Conclusion: We conclude that the levels of blood glucose, triacylglycerols, low-density lipoprotein cholesterol and high-density lipoprotein cholesterol differ significantly between ovarian cancer patients and the healthy control subjects. The risk of ovarian cancer was positively associated with the levels of blood glucose, triacylglycerols and low-density lipoprotein cholesterol, and negatively associated with levels of high-density lipoprotein cholesterol. Therefore, determination of blood glucose and serum lipids, particularly, triacylglycerols, low-density lipoprotein cholesterol may be helpful as diagnostic indicators of ovarian cancer (OC).

Intraoperative Blood Glucose Levels and Postoperative Acute Kidney Injury in Pediatric Patients Having Congenital Heart Surgery under Cardiopulmonary Bypass

Purpose:This study sought to explore the effect of intraoperative mean blood glucose levels and variability on postoperative acute kidney injury(AKI)in children undergoing congenital cardiac surgery.Methods:We conducted a prospective nested case-control study in children(age<18 years)undergoing congenital heart surgery with cardiopulmonary bypass(CPB)at the Fuwai Hospital between April 01,2022 and July 30,2022.Cases were individuals who developed AKI within the first postoperative 7 days(AKI group)and controls were those without AKI(Non-AKI group)according to KDIGO criteria.AKI and Non-AKI groups unmatched and 1:1 matched by age,sex,and baseline serum creatinine were separately analyzed.Multivariate logistic and conditional logistic regressions were used to assess the associations between blood glucose variables and AKI.Results:688 consecutively approached patients were included in the final analysis.On multivariate analysis,intra-CPB(adjusted odds ratio[OR]0.802;95%confidence interval[CI],0.706 to 0.912;p=0.001)and post-CPB(adjusted OR 0.830;95%CI,0.744 to 0.925;p=0.001)blood glucose levels were associated with postoperative AKI.There were no significant differences in pre-CPB blood glucose(adjusted OR 0.926;95%CI,0.759 to 1.129;p=0.446)or intraoperative glycemic fluctuations(adjusted OR 0.905;95%CI,0.723 to 1.132;p=0.382)between AKI and Non-AKI groups.Results based on matched cases and controls were consistent with those from the unmatched analyses.Conclusion:Higher intraoperative blood glucose levels during and after CPB were protective factors against postoperative AKI in pediatric patients after congenital heart surgery.

Detection and management of perioperative blood glucose abnormalities

Diabetes mellitus is a common chronic disease.With the improvement of living standards,the prevalence of diabetes mellitus in China is increasing.There are now more people with diabetes in China(>100 million)than in any other country.About half of these people with diabetes need to undergo at least one procedure in their lifetime.Diabetic patients have a much higher probability of perioperative dysglycemia than the normal population,which has a great impact on their prognosis.In addition,non-diabetic patients may also have abnormal blood glucose levels due to various reasons during the perioperative period,which will also lead to a series of adverse consequences.This ar ticle reviews the perioperative blood glucose management of patients to provide a reference for improving their health status.

Relationship Between Postprandial Blood Glucose,Fasting Insulin,and Glycated Hemoglobin Levels and Early Diabetic Nephropathy in Patients with Type 2 Diabetes Mellitus

Objective:To investigate the relationship between postprandial blood glucose(PBG),fasting insulin(FINS),and glycated hemoglobin(HbA1c)levels and early diabetic nephropathy in patients with type 2 diabetes.Methods:96 cases of type 2 diabetes mellitus treated in our hospital from May 2021 to May 2022 were selected as the research subjects.The patients were divided into two groups according to the urinary albumin excretion rate(UAER),with 53 cases in the type 2 diabetes group(UAER<30μg/min)and 43 cases in the early diabetic nephropathy group(30μg/min≤UAER<300μg/min).PBG,FINS,and HbA1c levels were detected in 87 healthy patients.Results:The levels of PBG,FINS,and HbA1c in the early diabetic nephropathy group were higher than those in the control group(P<0.01)and the type 2 diabetes group(P<0.01).Conclusion:PBG,FINS,and HbA1c are factors affecting the occurrence of diabetic nephropathy in patients with type 2 diabetes;thus,controlling the levels of PBG,FINS,and HbA1c can effectively prevent the occurrence of diabetic nephropathy in type 2 diabetes mellitus.

Using fluorodeoxy-D-glucose-positron emission tomography to monitor neoadjuvant chemotherapy response in sarcoma:A meta-analysis

AIM： To systematically evaluate the accuracy of 18-fu-orodeoxy-D-glucose-positron emission tomography （18-FDG PET） to assess response to neoadjuvant che-motherapy in bone and soft tissue sarcomas.METHODS： Studies published in English language re-garding the accuracy of F-18 FDG PET for the indication were retrieved from MEDLINE. The QUADAS tool was utilized for methodological quality appraisal. Relevant data were extracted, and quantitative data synthesis included pooled estimation and subgroup analysis. RESULTS： A total of ffteen studies involving 420 pa-tients with pathologically confrmed sarcoma were col-lected. Methodological quality was relatively high. The pooled sensitivity and specifcity of PET to predict histo-pathological response were 87% （95%CI： 81%-91%） and 83% （95%CI： 77%-87%）, respectively. Ten stud-ies employed a lower standardized uptake value （SUV） after chemotherapies （mostly 2.5） and/or a higher SUV reduction rate （mostly around 50%） as PET criteria of good response. Subgroup analysis showed that PET ex-hibited a signifcantly better specifcity in osteosarcoma （OS） and Ewing sarcoma （ES） than in soft-tissue sarco-ma （STS） （91% vs 75%, P 〈 0.05）, and a higher speci-fcity in pediatric patients than in adults （90% vs 74%, P 〈 0.01）. PET yielded a lower specifcity in ifosfamide-contained chemotherapies than in the alternative regi-men （70% vs 97%, P 〈 0.01）.CONCLUSION： F-18 FDG PET is promising to predict neoadjuvant therapy response in sarcoma, especially in pediatric patients with OS or ES. Certain chemothera-peutic agents could potentially cause false positives of PET.

Effects of binuclear copper(Ⅱ)threonine complex on blood glucose, lipids and protection of the hearts and kidneys in diabetic mice

Aim To study the effects of binuclear copper （Ⅱ） threonine complex （Cu2 （Thr）4） as analogue of superoxide dismutase （SOD） on blood glucose, blood lipids and vessels of hearts and kidneys in diabetic mice. Methods Diabetic mouse model was established by intraperitioneal injection of alloxan. Low, middle, and high doses of Cu2（Thr）4 at 0.002%, 0.02% and 0.1% were given respectively to diabetic mice following lavage. The fasting blood glucose was determined after the diabetic mice were given Cu2 （Thr）4 for 0, 30, and 45 d. The diabetic mice were killed on the 45th day. Then glycosylated hemoglobin （HbAlc） and blood lipids were assayed, and pathologic changes in hearts and kidneys stained with HE were observed. Results Compared with the control group in which the diabetic mice were given distilled water, the value of blood glucose reduced significantly in middle dose group （P 〈 0.01 ）, followed by that in low dose group （P 〈 0.05）. TC level reduced markedly and HDL level increased significantly in all three treatment groups （P 〈 0.05）. Especially in middle dose group, cardiac muscle fibers were neatly arranged, nucleus and cytoplasm well distributed, glomeruli showing normal structure, cells well distributed and staining being normal. Conclusion Cu2 （Thr）4 reduces blood glucose, regulates blood lipids, and play protective action on the vessels of hearts and kidneys in diabetic mice. The effects of it in middle dose were better than those of other doses.
