Predictive value of the C-reactive protein/albumin ratio in tsutsugamushi disease complicated with organ function damage / 中华急诊医学杂志

Objective:To explore the predictive value of the serum C-reactive protein (CRP)/albumin (ALB) ratio (CAR) for organ damage in tsutsugamushi disease.Methods:The clinical data of 166 patients with tsutsugamushi disease admitted to the First Affiliated Hospital of Wenzhou Medical University from January 1, 2010 to December 31, 2020 were retrospectively analyzed. The patients were divided into the organ damage group (72 cases) and non-organ damage group (94 cases) according to the organ damage criteria. The general data and laboratory test results of the two groups of patients were compared. The significant indicators of univariate analysis were analyzed by multivariate logistic regression analysis. The receiver operating characteristic (ROC) curve and area under the curve (AUC) were used to analyze the predictive value of CAR for organ damage in patients with tsutsugamushi disease.Results:There were no significant differences in age, sex, days of fever, and admission body temperature between the organ damage group and non-organ damage group ( P>0.05). However, the body mass index, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ), sequential organ failure assessment (SOFA), length of hospital stay, hospitalization expense, percentage of neutrophils (NEUT), lymphocyte count, procalcitonin, CRP, and CAR in the organ damage group were significantly higher than those in the non-organ damage group ( P<0.05), and ALB was significantly lower than that in the non-organ damage group ( P<0.05). Multivariate logistic regression analysis showed that APACHEⅡ( P=0.039), NEUT ( P=0.003), and CAR ( P=0.011) were independent risk factors for tsutsugamushi disease complicated by organ damage. The ROC curve showed that the AUCs of APACHEⅡ, NEUT, and CAR were 0.655, 0.716, and 0.727, respectively. When the cut-off value of CAR was 2.86, the sensitivity was 55.6%, and the specificity was 79.8%. Conclusions:Elevated CAR is an independent risk factor for tsutsugamushi disease complicated with organ damage and can be used as an important indicator to evaluate the presence or absence of organ damage in patients with tsutsugamushi disease.

Role of multidisciplinary cooperation in the diagnosis and treatment of pelvic floor disorder disease / 中华胃肠外科杂志

The pelvic floor disorder disease (PFDD) typically originates from supportive tissue defects or injuries in the pelvic floor with a wide spectrum of symptoms such as urinary incontinence, pelvic organ prolapse, sexual dysfunction, fecal incontinence and chronic pelvic pain. But its etiology is complex, involving multiple systems and organs. So the best management of PFDD requires the implementation of multidisciplinary team (MDT). Pelvic floor centers have been developed abroad to provide pelvic floor services. In the setting of PFDD, the concept of MDT starts lately and develops slowly in China. The MDT approach was demonstrated to improve general rehabilitation, psychological state and quality of life. However, there is no unified standardization for MDT diagnosis and treatment of PFDD at home and abroad. Meanwhile, the personnel composition, responsibilities, training, and operation mode of the MDT need to be further developed. Perfecting the management mode of MDT team members, establishing standardized training programs and assessment criteria play crucial role in the future development of MDT in PFDD.

Significance of the intact of the fascia propria in protection of pelvic plexus during total mesorectal excision / 中华胃肠外科杂志

Total mesorectal excision (TME) is the gold standard of surgical treatment for mid and low rectal cancer. It aims to improve the oncological outcomes as well as preserve anal sphincter, sexual and urinary function. Compared with sympathetic nerve injury alone, pelvic plexus and neurovascular bundle (NVB) injury has significant effect on postoperative sexual dysfunction, especially erectile function. Since the lateral surgical plane of TME is narrow and densely packed, dissecting outside the plane causes pelvic plexus injury, while dissecting inside it results in residual mesorectum. In this commentary, we review the research progress of lateral fascial anatomy of TME, and describe the anatomical characteristics of rectosacral fascia based on our previous research results. The prehypogastric fascia acts as a "fascia barrier" when dissecting the lateral space constantly from posterior to anterior. In addition, the pelvic plexus fuses with the prehypogastric fascia which is considered as the outer side layer of rectosacral fascia laterally. Thus, the rectosacral fascia should be dissected at the level of S4 vertebral body posterior to the rectum in an arc shape and then enter the superior-levator space. Before dissecting the lateral spaces, the anterior space of the rectum should be dissected first. After an "U" shape cutting of the Denonvilliers' fascia, the lateral space should be dissected from anterior to posterior. Finally, the lateral attachment of rectosacral fascia is transected to ensure the integrity of the mesorectum without damaging the pelvic plexus.

Pros and cons of perioperative therapy in the protection of organ function in rectal cancer / 中华胃肠外科杂志

The goal of rectal cancer treatment should be to better protect organ function and improve patients' quality of life on the basis of ensuring radical resection. The current evidence has proved the superiority of perioperative chemoradiotherapy in reducing local recurrence and improving long-term survival. From the perspective of organ function protection, however, perioperative chemoradiotherapy has both disadvantages and advantages. Despite the great help in improving long-term outcomes, adverse reactions of chemoradiotherapy can aggravate defecation, urination and sexual dysfunction. Also, for patients with significant or complete remission, if the treatment strategy of local resection or close follow-up is selected, organ function can be preserved to the greatest extent. The key to the choice of treatment is to evaluate preoperatively whether pathological complete response is achieved. It should be kept in mind that preserving organ itself is not the same as protecting organ function. For patients who need perioperative chemoradiation, the optimal treatment methods should be chosen based on the patient's condition. Surgeons should fully evaluate organ function before operation, select the appropriate treatment strategy, pay special attention to the protection of important organs and nerves during surgeries, and carry out close postoperative follow-up and organ function rehabilitation as soon as possible, so as to reduce the incidence of dysfunction and the impact on the quality of life.

Chinese expert consensus on the protection of pelvic organ function in the rectal cancer surgery / 中华胃肠外科杂志

With the development of surgical techniques, adjuvant and neoadjuvant therapy, the survival of patients with rectal cancer after surgery has improved significantly, while the organ dysfunction remains an important factor affecting quality of life of patients. In order to improve the awareness of Chinese surgeons in organ function protection for the treatment of rectal cancer, standardize the evaluation method and surgical procedure, reduce the incidence of organ dysfunction, and ultimately improve the quality of life of patients, Colorectal and Anal Function Surgeons Committee of China Sexology Association, Organ Function Protection Committee of Chinese College of Colorectal Cancer, and Colon and Rectal Surgeons Committee of Chinese College of Surgeons jointly organized experts in related fields, in combination with domestic and foreign research and clinical practice, to discuss and formulate a Chinese expert consensus on the protection of pelvic organ function in the rectal cancer surgery, including the definition, risk factors, assessment methods, prevention and treatment of organ dysfunction after rectal cancer surgery.

Chinese expert consensus on early prevention and intervention of sepsis

Sepsis is currently a major problem and challenge facing the medical community. With rapid development and progress of modern medicine, researchers have put more and more attention on sepsis; meanwhile, the morbidity and mortality of sepsis remains high despite great efforts from experts in various fields. According to updated guidelines, sepsis is defined as life-threatening organ dysfunction caused by a dysregulated host response to infection. Infection is the initial step of sepsis progression, and development from infection to sepsis is a complex pathophysiological process, including pathogen invasion, cytokine release, capillary leakage, microcirculation dysfunction, etc. which finally leads to organ metabolic disorders and functional failure. According to the latest recommended international guidelines of Sepsis 3.0, the presence of infection and SOFA score ≥ 2 are considered as the diagnostic criteria for sepsis, and the 'rescue' measures mainly focus on reversal of organ dysfunction. However, despite nearly two decades of efforts, the 'Save Sepsis Campaign' has not achieved satisfactory results. Emergency medicine is the frontier subject of acute and severe illness which treats patients with acute infections at the earliest. If at this stage, physicians can predict the possibility of sepsis progression from demographic characteristics, localize the pathogen and infection, detect the inflammatory storms by tests of cytokines and evaluate the severity of the infection with more effective clinical scoring system, and then take effective measures to prevent infection from developing into sepsis in high-risk patients, the morbidity and mortality of sepsis in patients with acute infection will be greatly reduced. Based on this situation, Chinese emergency medicine experts proposed the concept of 'preventing and blocking' sepsis, and launched the nationwide 'Preventing Sepsis Campaign in China (PSCC)' nationwide. The main concept is summarized as 'three early and two reduces' which includes early detection, early diagnosis and early intervention during the 'pre-symptomatic' and 'peri-septic' stage in order to reduce the incidence of sepsis and it proposed a new approach for diagnosis and treatment of acute severe infection. This consensus is jointly advocated, discussed and written by four academic associations in the field of emergency medicine and five scholarly publishing organizations. More than 40 experts from fields of emergency medicine, critical care medicine, infectious diseases, pharmacy and laboratory medicine have participated in several rounds of deliberation and finally reached consensus on the criteria of identifying patients with acute infection, taking anti-infective treatments, screening of high-risk patients with sepsis, detection and treatment of inflammatory storm, protection of vascular endothelial cells and the regulation of coagulation function, as well as strategies of liquid support and organ function protection etc. The consensus summarizes the commonly used clinical diagnosis criteria and treatment measures of sepsis both in Western medicine and traditional Chinese medicine for clinicians in order to provide evidence for the diagnosis and treatment of the disease.

Organ function support in patients with coronavirus disease 2019: Tongji experience / 医学前沿

Coronavirus disease 2019 (COVID-19) is a highly contagious disease and a serious threat to human health. COVID-19 can cause multiple organ dysfunction, such as respiratory and circulatory failure, liver and kidney injury, disseminated intravascular coagulation, and thromboembolism, and even death. The World Health Organization reports that the mortality rate of severe-type COVID-19 is over 50%. Currently, the number of severe cases worldwide has increased rapidly, but the experience in the treatment of infected patients is still limited. Given the lack of specific antiviral drugs, multi-organ function support treatment is important for patients with COVID-19. To improve the cure rate and reduce the mortality of patients with severe- and critical-type COVID-19, this paper summarizes the experience of organ function support in patients with severe- and critical-type COVID-19 in Optical Valley Branch of Tongji Hospital, Wuhan, China. This paper systematically summarizes the procedures of functional support therapies for multiple organs and systems, including respiratory, circulatory, renal, hepatic, and hematological systems, among patients with severe- and critical-type COVID-19. This paper provides a clinical reference and a new strategy for the optimal treatment of COVID-19 worldwide.

Progress on application of marginal donor liver and organ function maintenance in liver transplantation / 器官移植

Liver transplantation is the only effective method to treat various end-stage liver diseases. The shortage of standard donor liver is the main factor limiting the development of liver transplantation, whereas the application of marginal donor liver has significantly expanded the source of donor liver. New technologies, such as extracorporeal membrane oxygenation (ECMO), mechanical perfusion and hypothermia, can significantly improve the quality of marginal donor liver, which has good development prospects in organ function maintenance. This article reviews the common types of marginal donor liver and the application of related novel technologies in the maintenance of marginal donor liver function.

Background:@#Increased extravascular lung water (EVLW) in shock is common in the critically ill patients. This study aimed to explore the effect of cardiac output (CO) on EVLW and its relevant influence on prognosis.@*Methods:@#The hemodynamic data of 428 patients with pulse-indicated continuous CO catheterization from Department of Critical Care Medicine, Peking Union Medical College Hospital were retrospectively collected and analyzed. The patients were assigned to acute respiratory distress syndrome group, cardiogenic shock group, septic shock group, and combined shock (cardiogenic and septic) group according to their symptoms. Information on 28-day mortality and renal function was also collected.@*Results:@#The CO and EVLW index (EVLWI) in the cardiogenic and combined shock groups were lower than those in the other groups (acute respiratory distress syndrome group vs. cardiogenic shock group vs. septic shock group vs. combined shock group: CO, 5.1 [4.0, 6.2] vs. 4.7 [4.0, 5.7] vs. 5.5 [4.3, 6.7] vs. 4.6 [3.5, 5.7] at 0 to 24 h, P=0.009; 4.6 [3.8, 5.6] vs. 4.8 [4.1, 5.7] vs. 5.3 [4.4, 6.5] vs. 4.5 [3.8, 5.3] at 24 to 48 h, P=0.048; 4.5 [4.1, 5.4] vs. 4.8 [3.8, 5.5] vs. 5.3 [4.0, 6.4] vs. 4.0 [3.2, 5.4] at 48 to 72 h, P=0.006; EVLWI, 11.4 [8.7, 19.1] vs. 7.9 [6.6, 10.0] vs. 8.8 [7.4, 11.0] vs. 8.2 [6.7, 11.3] at 0 to 24 h, P < 0.001; 11.8 [7.7, 17.2] vs. 7.8 [6.3, 10.2] vs. 8.7 [6.6, 12.2] vs. 8.0 [6.6, 11.1] at 24 to 48 h, P < 0.001; and 11.3 [7.7, 18.7] vs. 7.5 [6.3, 10.0] vs. 8.8 [6.3, 12.2] vs. 8.4 [6.4, 11.2] at 48 to 72 h, P < 0.001. The trend of the EVLWI in the septic shock group was higher than that in the cardiogenic shock group (P < 0.05). Moreover, there existed some difference in the pulmonary vascular permeability index among the cardiogenic shock group, the septic shock group, and the combined shock group, without statistical significance (P > 0.05). In addition, there was no significant difference in tissue perfusion or renal function among the four groups during the observation period (P > 0.05). However, the cardiogenic shock group had a higher 28-day survival rate than the other three groups [log rank (Mantel-Cox) = 31.169, P < 0.001].@*Conclusion:@#Tissue-aimed lower CO could reduce the EVLWI and achieve a better prognosis.

Emphasize on the postoperative anal function of middle and low rectal cancer patients / 中国实用外科杂志

Organ function preservation emphasizes the application of various therapeutic techniques to avoid or reduce the influence of tumor treatment process on the normal function of cancer organs and adjacent organs under thepremise of ensuring the best prognosis of oncology. Modern surgical treatment of middle and low rectal cancer does requireanal organ function preservation, but the current rectal cancer guidelines lack guidance on how to protect organ function. Inthe author's opinion,modern colorectal surgeons should recognize that anal function is an important factor affecting the quality of life after rectal cancer surgery. Functional considerations should be raised to the same level as techniqueas to whether the patient should preserve the anus. Correct evaluation of postoperative defecation function of patients isthe basis of selecting anal preservation indications.Preoperative evaluation of risk factors for anal dysfunction are helpful to predict postoperative functional status. The rational use of multidisciplinary strategies is recommended to reduce surgical trauma and improve anastomosis techniques to achieve functional preservation in middle and low rectal cancer.

U50488H improves organ function after septic shock / 中华急诊医学杂志

Objective To investigate the effect of U50488H on the ultrastructure and organ function in septic shock rats. Methods Forty SD male rats were randomly(random number) divided into 5 groups: sham group, septic shock group, U50488H+septic shock group, nor-BNI+U50488H+septic shock group, and nor-BNI+septic shock group, with 8 rats in each group. Cecal ligation and puncture (CLP) was performed to induce septic shock in the septic shock group. Rats in the U50488H+septic shock group were treated with U50488H injection by intravenous at the shock point, and other procedures were the same as the septic shock group. Rats in the nor-BNI+U50488H+septic shock group were treated with nor-BNI injection by intravenous 3.5 h after abdomen closed, and other procedures were the same as the U50488H+septic shock group. Except for U50488H injection, rats in the nor-BNI+septic shock group received procedures the same as the nor-BNI+U50488H+septic shock group. Albumin, cardiac troponin I (cTnI) and N terminal pro B type natriuretic peptide (NT-proBNP) in serum were measured at abdomen-closed, 3, 6, and 12 h after CLP. The changes of histology and ultramicro structure under electron microscope of lung, heart, liver and kidney of rats were observed at 12 h after CLP. Statistical analysis was performed using SPSS 19.0. Comparison among groups was carried out using ANOVA, and Student's t-test was used for multiple comparisons as post-hoc. Results At 6 and 12 h of CLP, serum albumin of the septic shock group were significantly lower than those of the sham group (P<0.01), while those in the cTnI and NT-pro BNP groups were higher at 3, 6, and 12 h of CLP (P<0.01). Compared with the septic shock group, serum albumin of the U50488H+septic shock group increased significantly (P<0.01), whereas the serum levels of cTnI and NT-pro BNP decreased remarkably at 3, 6 and 12 h of CLP (P < 0.05, P < 0.01, respectively). Compared with the sham group, the alveolar wall was severely damaged, the alveolar septum and blood vessel wall were thickened obviously; the myocardial fiber was swollen, necrotic, and the infiltration of central granulocyte was increased significantly; hepatocyte showed edema, vacuolar-like steatosis, fatty degeneration, spotty and focal necrosis; and slight edema and vacuolar degeneration were found in the glomerulus endothelial in the septic shock group. Compared with the septic shock group, the ultrastructural damage of the lung, heart, liver and kidney of the U50488H+ septic shock group was significantly improved. All the above effects of U50488H could be blocked by nor-BNI (a selective κ-opioid receptor antagonist) (P<0.01). Conclusions U50488H can promote the recovery of serum albumin, and protect organ function in septic shock rats.

Therapeutic effect of mild hypothermia on the inflammatory response and outcome in perioperative patients with acute Stanford type A aortic dissection: A randomized controlled trial / 中国胸心血管外科临床杂志

@#Objective To explore the therapeutic effect of mild hypothermia on the inflammatory response, organ function and outcome in perioperative patients with acute Stanford type A aortic dissection (AAAD). Methods From February 2017 to February 2018, 56 patients with AAAD admitted in our department were enrolled and randomly allocated into two groups including a control group and an experimental group. After deep hypothermia circulatory arrest during operation, in the control group (n=28), the patients were rewarmed to normal body temperatures (36 to 37 centigrade degree), and which would be maintained for 24 hours after operation. While in the experimental group (n=28), the patients were rewarmed to mild hypothermia (34 to 35 centigrade degree), and the rest steps were the same to the control group. The thoracic drainage volume and the incidence of shivering at the first 24 hours after operation, inflammatory indicators and organ function during perioperation, and outcomes were compared between the two groups. There were 20 males and 8 females at age of 51.5±8.7 years in the control group, 24 males and 4 females at age of 53.3±11.2 years in the experimental group. Results There was no obvious difference in the basic information and operation information in patients between the two groups. Compared to the control group, at the 24th hour after operation, the level of peripheral blood matrix metalloproteinases (MMPs) was lower than that in the experimental group (P=0.008). In the experimental group, after operation, the awakening time was much shorter (P=0.008), the incidence of bloodstream infection was much lower (P=0.019). While the incidence of delirium, acute kidney injury (AKI), hepatic insufficiency, mechanical ventilation duration, intensive care unit (ICU) stays, or hospital mortality rate showed no statistical difference. And at the first 24 hours after operation, there was no difference in the thoracic drainage volume between the two groups, and no patient suffered from shivering. Conclusion The mild hypothermia therapy is able to shorten the awakening time and reduce the incidence of bloodstream infection after operation in the patients with AAAD, and does not cause the increase of thoracic drainage volume or shivering.

Prevalence of Hypertension and Prognosis of Associated Dysfunction on Specific Organ Function among Ghanaian Adolescent Students

Aims: To determine prevalence of hypertension among adolescent students and prognosis of associated dysfunction on specific organ function among adolescent students.Study Design:A cross-sectional study.Place and Duration of Study:Three senior high schools (SHS) in Ashanti region of Ghana, namely Anglican SHS, Konongo Odumase SHS and Bonwire SHS, between October 2016 and March 2017.Methodology:A multi-stage sampling method was used to select 909 adolescents from the three SHS. Participants were screened for elevated blood pressure. A total of 142 participants had high blood pressure and were used for this study. Anthropometries; body mass index (BMI), percent body fat (%BF), visceral fat (VF), waist circumference (WC) and blood pressure levels were measured with recommended instruments and biochemical and haematological parameters were assessed. Sociodemographic data were taken with questionnaire.Results:Out of 909 adolescent students, the prevalence of high blood pressure from first screening was 9.1%.However, upon second screening from those with high blood pressure from the first screening, prevalent rate for high blood pressure had declined to 1.21%.Hypertension was higher in males (10.7%), compared to females (4.5%, P= 0.658). There were no significant differences between BMI (P= 0.847), %BF (P= 0.501), VF (P= 0.195), WC (P= 0.450) among hypertensive, pre-hypertensive and normotensive participants. There was no significant mean difference betweenurea (P= 0.236), creatinine (P= 0.995), serum sodium (P= 0.126), serum chloride (P= 0.516), serum potassium (P= 0.878) and alanine aminotransferase (ALT) levels (P= 0.397) and blood pressure status. Total cholesterol (P= 0.765), triglycerides (P= 0.381), HDL (P= 0.777) and LDL (P= 0.768) was not significantly associated with blood pressure status.Conclusions:Participants had high blood pressure level. Despite the prevalence of high blood pressure among adolescent population, it had no impact to cause anydysfunction in kidney, cardiovascular and liver. Hence, appropriate diet and lifestyle management are needed to prevent early and/or future complication of hypertension among adolescents

Methods A prospective randomized controlled trial was conducted. EHS patients admitted to intensive care unit of the 159th Hospital of People's Liberation Army and the First Affiliated Hospital of Zhengzhou University from June 2015 to June 2017 were enrolled. The patients were divided into 2, 4, 6 hours start hypothermia treatment groups according to the random number table method, the mild hypothermia was initiated at 2, 4 and 6 hours after the disease onset respectively, and the methods were the same in each group. After treatment of 2, 12, 24 hours, the venous blood in the three groups was collected to detect serum cardiac troponin I (cTnI) with chemiluminescence method, MB isoenzyme of creatine kinase (CK-MB) with immunosuppressive method, creatinine (Cr) with creatine oxidase method, β2-microglobulin (β2-MG) with turbidimetry, alanine aminotransferase (ALT) and aspartate aminotransferase (AST) with enzyme method. Multiple organ dysfunction syndrome (MODS) within 24 hours after treatment was recorded. Linear regression analysis of the correlation between mild hypothermia start-up time and MODS was done. Results Ninety-three cases of EHS were included,with 32, 31 and 30 patients in 2, 4, 6 hours start treatment groups respectively. There were no significant differences in gender, age, core temperature, onset time to admission, Glasgow coma scale (GCS), acute physiology and chronic health evaluation system Ⅱ(APACHE Ⅱ) score at admission among the three groups. There were no significant differences in the levels of serum cTnI, CK-MB, Cr, β2-MG, ALT and AST at 2 hours after treatment. But with the prolongation of the treatment time, all indicators gradually increased. And the earlier start of the mild hypothermia, the less significant of the above indexes. All indexes in 2 hours start treatment group were significantly lower than those of 2 hours and 6 hours start treatment groups at 24 hours after treatment [cTnI (ng/L): 49.53±9.25 vs. 56.52±10.05, 64.57±11.21; CK-MB (U/L):51.47±11.83 vs. 57.87±7.43, 64.40±7.93; Cr (μmol/L): 140.97±11.33 vs. 148.16±10.39,155.57±8.65; β2-MG (mg/L): 10.28±1.46 vs. 11.58±2.13, 12.93±1.98; ALT (U/L): 248.53±75.47 vs. 341.42±129.58, 425.77±101.23;AST (U/L): 197.25±42.59 vs. 292.81±58.49, 351.20±60.41, all P < 0.05]. There was significant difference in the incidence of MODS in 2, 4, 6 hours start treatment groups [43.75% (14/32), 64.52% (20/31), 80.08% (24/30), χ2= 8.761, P = 0.013]. Linear regression analysis showed that the earlier onset time of mild hypothermia, the lower incidence of MODS (R2= 0.915, P = 0.013). Conclusion The application of mild hypothermia in 2 hours can effectively protect the physiological function of EHS organs and reduce the incidence of MODS.

Risk assessment of cardiovascular and other target organs damage in patients with type 2 diabetes and different body mass indexes / 重庆医学

Objective To investigate the risk of cardiovascular and other target organs damage in the patients with type 2 di abetes mellitus(T2DM) and different body mass indexes (BMI).Methods One hundred and twenty-six patients with T2DM admitted to our hospital from January 2014 to January 2016were prospectively collected,including 57 cases in the study group (BMI≥25 kg/m2) and 69 cases in the control group (18.5 kg/m2≤BMI＜25 kg/m2).The clinical featuresof the two groups were analyzed,and the correlation between BMI and related indexes of target organ damage [carotid arte ry intima media thickness (IMT),arterial stiffness index,coronary heart disease index and glomerular filtration rate] were analyzed.Results There was no statistically significant difference in fasting blood glucose between the two groups (P=0.953),BMI in the study group was significantly higher than that in the control group (P=0.000).When compared with the.control group,the study group showed a significantly increase in age (P=0.038);a significant increase in systolic blood pressure (P=0.000);a significantly increase in diabetic family history (P=0.000);a significant increase in total cholesterol (P=0.012);a significant increase in triglycerides (P=0.000);a significant decrease in high density lipoprotein (P=0.003);a significant increase in HOMA-IR level (P =0.000);a significant decrease in HOMA-β level (P=0.000);a significant increase in IMT level (P=0.000);a significant increasein arterial stiffness index (P=0.000);a significant increase in coronary heart disease index (P:0.001);and a significant decrease in glomerular filtration rate (P=0.000).The Pearson linear correlation analysis showed that BMI was correlated with IMT,atherosclerosis index,coronary heart disease index and glomerular filtration rate,the r values were 0.234,0.257,0.294 and 0.211 respectively(all P=0.000).Conclusion The BMI level in the patients with T2DM is related to cardiovascular and renal function damage.
