A questionnaire and telephone survey was conducted on 246 patients with chronic liver diseases in the Outpatient Clinic from August 2010 to May 2011.The distribution of diseases and the causes of losing follow-up were analyzed. Most subjects in this survey (182/246,74.0% ) were patients with chronic viral hepatitis( HBV or HCV)and cirrhosis; and their follow-up status was better than others (X2 =12.382,P < 0.05). There were no differences in gender( X2 =10.137,P > 0.05),but significant differences in age ( X2 =31.783,P < 0.05 ) and educational levels ( X2 =32.803,P < 0.05 ) between patients with chronic viral hepatitis and cirrhosis and patients with other liver diseases.The main causes of losing follow-up were neglect of disease by patients (38.3%) and lack of good communication between doctors and patients ( 18.3% ).It is important to reinforce the understanding and awareness of chronic liver diseases for patients.
3.Independent association between sarcopenia and nonalcoholic fatty liver disease
Journal of Clinical Hepatology 2019;35(6):1377-1379
Nonalcoholic fatty liver disease (NAFLD) is a metabolic disease which can progress to liver fibrosis, liver cirrhosis, and liver cancer. Sarcopenia is an age-related disease and metabolic factors play an important role in its pathogenesis. NAFLD and sarcopenia share a variety of metabolic pathophysiological mechanisms. Further studies are needed to determine whether there is an association between NAFLD and sarcopenia and whether they are predisposing factors or risk factors for disease progression for each other, in order to help with better prevention, treatment, and prognostic evaluation of the two diseases in clinical practice. This article reviews the independent association between NAFLD and sarcopenia.

Objective To clarify the role of insulin resistance on spontaneous recanalization of infarct-relat-ed arteries in the early phase of acute ST-elevation myocardial infarction (STEMI) in patients with normal glucose tolerance. Methods 141 consecutive patients with normal glucose tolerance and acute STEMI were enrolled in our study. Subjects were divided into TIMI 0-1 group (n =91 ) and TIMI 2-3 group (n =50) by primary coronary angi-ngraphy (CAG). The Gemini score and 0-3-vessel disease score estimated the severity and extent of coronary artery disease (CAD). Metabolic parameters and homeostasis model assessment for insulin resistance (IRI) were deter-mined. Results Serum level of fasting insulin, IRI and Gemini score were higher in TIMI 0-1 group than in TIMI 2-3 group [ (11.52±6.22)mU/L vs (7.54±3.65)mU/l,(2.79±2.32) vs (1.73±1.26),(59.17±26.95) vs ( 38.46±22.74) ( P <0.01)]. IRI was positively associated with Gemini score (r=0.185,P <0.05 ). Multivariate Logistic regression analysis revealed that IRI was independent risk factor influencing spontaneous recanalization of in-farct-related urteries(OR=2.87,95% CI=1.09-7.57,P<0.05). Conclusion Insulin resistance is independent risk factor influencing spontaneous recanalizafion of infarct-related arteries in the early phase of acute STEMI in pa-tients with normal glucose tolerance.

Objective To compare the effects of ticagrelor and clopidogrel on platelet aggregation rate, myocardial perfusion and prognosis in patients with acute myocardial infarction. Methods One hundred and sixty-nine patients with acute ST segment elevation myocardial infarction (STEMI) and emergency percutaneous coronary intervention (PCI) were recruited and randomly divided into ticagrelor group (85 cases) and clopidogrel group (84 cases). The TIMI blood flow before and after PCI was recorded, and the ST segment fall rate of 1 h ECG after PCI was calculated. The platelet aggregation rate was measured. After 12 months' follow-up, the incidence of major adverse cardiac events (MACE) was recorded. The Logistic regression analysis was used to discover the factors of MACE. Results One hundred and sixty-nine patients with acute STEMI were recruited including 85 cases treated with ticagrelor and 84 cases in clopidogrel group. The ECG ST segment fall rate after PCI in ticagrelor group was significantly higher than that in clopidogrel group: (61.3 ± 30.7)% vs. (47.8 ± 26.6)%, P<0.05. The platelet aggregation rate 2 h, 24 h and 7 d after PCI in ticagrelor group was significantly lower than that in clopidogrel group (P<0.05). MACE occurred in 19 cases (22.4%) in ticagrelor group and in 21 cases (25.0%) in clopidogrel group, and there was no significant difference (P > 0.05). Multiple Logistic regression analysis revealed that age and ECG ST segment fall rate were independent risk factors for MACE (P<0.05). Conclusions Compared with clopidogrel, ticagrelor can effectively reduce platelet aggregation rate and accelerate ST segment fall in STEMI patients, but their long-term prognosis is similar.

Objective To investigate the predictive value of serum adiponectin level on morbidity of acute myocardial infarction, and to evaluate its impact on prognosis in patients with acute myocardial infarction after percutaneous coronary intervention (PCI). Methods We prospectively recruited patients with acute ST segment elevation myocardial infarction (STEMI) who had underwent primary PCI. Their serum adiponectin levels were measured. The TIMI blood flow classification of culprit vessel was recorded after PCI. Echocardiography was performed in 24 h after PCI to evaluate left ventricular ejection fraction (LVEF). Major adverse cardiac events (MACE) were recorded including cardiac death, recurrent nonfatal myocardial infarction, target vessel reascularization, and readmission for heart failure after 18 months′ followed-up. Results 108 consecutive patients with STEMI and 38 control patients without coronary artery stenosis were recruited. The serum adiponectin level in STEMI group was significantly lower than that in control: (1 413.9 ± 218.8) ng/L vs.(1 756.3 ± 205.5) ng/L (P<0.01). STEMI patients with LVEF < 50% had lower serum adiponectin level compared with LVEF ≥50%: (1 334.1 ± 226.3) ng/L vs. (1 453.0 ± 213.8) ng/L , P<0.01. The serum adiponectin level in the TIMI 0-2 group after PCI was significantly lower than that in the TIMI 3 group:(1 350.7 ± 214.9) ng/L vs. (1 430.6 ± 218.5) ng/L, P < 0.01. Multiple logistic regression analysis revealed that lower serum adiponectin level was an independent predictor of STEMI ( OR=0.992, 95% CI 0.987-0.996, P<0.01). MACE occurred in 22 patients (20.4% ). Cox regression analysis revealed that lower serum adiponectin level remained an independent predictor of MACE ( OR=0.996, 95% CI 0.993-0.999, P < 0.01). Conclusions Lower serum adiponectin level is significantly associated with morbidity of STEMI and adverse prognosis in patients with acute myocardial infarction.

OBJECTIVE:
To evaluate the effectiveness of laparoscopic Roux-en-Y gastric bypass (LRYGB) surgery for treatment of type 2 diabetes (TD) in patients with a body mass index (BMI) < 27.5 kg/m.
METHODS:
We retrospectively analyzed the data of patients who underwent LRYGB surgery from March, 2012 to June, 2018 in the General Hospital of Guangzhou Military Command and Jinshazhou Hospital of Guangzhou University of Chinese Medicine. The changes in the parameters of glucose metabolism and physical indicators of the patients in the first, second and third years after the surgery were analyzed in patients in low BMI group and high BMI group.
RESULTS:
All the 74 patients underwent LRYGB successfully without conversion to open surgery. One year after the surgery, fasting blood glucose (FBG), HbA1c, postprandial blood glucose, fasting insulin, HOMA-IR, fasting C-peptide, BMI, body weight and waistline were significantly improved compared with their preoperative values in low BMI group ( < 0.05). At 2 years after the operation, FBG, HbA1c, postprandial blood glucose, HOMA-IR, BMI, body weight and waistline were significantly improved compared with the preoperative values in low BMI group ( < 0.05). In the third year, FBG, HOMA-IR, fasting C-peptide, body weight and waistline were significantly improved compared with the preoperative values in low BMI group ( < 0.05). There was no significant difference in the parameters of glucose metabolism and islet function between low BMI group and high BMI group at different stages. No serious complications occurred in these patients after the surgery.
CONCLUSIONS
LRYGB is effective for treatment of T2D in Chinese patients with a BMI < 27.5. After the surgery, the patient show reduced waistline without significant weight loss. The long-term results of the surgery still require further investigations with a larger samples and longer follow-up.
