Glioblastoma (GBM) exhibits profound metabolic plasticity for survival and therapeutic resistance, while the underlying mechanisms remain unclear. Here, we show that GBM stem cells (GSCs) reprogram the epigenetic landscape by producing substantial amounts of phosphocreatine (PCr). This production is attributed to the elevated transcription of brain-type creatine kinase (CKB), mediated by Zinc finger E-box binding homeobox 1 (ZEB1). PCr inhibits the poly-ubiquitination of the chromatin regulator bromodomain containing protein 2 (BRD2) by outcompeting the E3 ubiquitin ligase SPOP for BRD2 binding. Pharmacological disruption of PCr biosynthesis by cyclocreatine leads to BRD2 degradation and a decrease in its targets' transcription, which inhibits chromosome segregation and cell proliferation. Notably, cyclocreatine treatment significantly impedes tumor growth and sensitizes tumors to a BRD2 inhibitor in mouse GBM models without detectable side effects. These findings highlight that high production of PCr is a druggable metabolic feature of GBM and a promising therapeutic target for GBM treatment.

This study investigated the conditions of abandoned, lost, discarded fishing gear (ALDFG) in natural and artificial reef zones and removed it afterward in Penghu Islands. Various feasible suggestions for improving ALDFG management were proposed for the county government to manage and reduce the generation of ALDFG in the future and maintain the marine ecosystem. This study divided the ocean areas of Penghu into five sub-areas for carrying out research and surveys. 165 boat trips of ALDFG investigation and removal were conducted from July 2018 to October 2019. The results show the ALDFG in natural reef areas is mostly large-mesh gillnets (26 %). The rest are single-layer bottom gillnets (21 %) and multi-layer bottom gillnets (20 %). In line with the recent efforts of the Penghu County Government to address ALDFG, it is recommended that the participation of citizen scientists and the promotion of ocean education can be utilized for fishery co-management in Penghu.

BACKGROUND: The benefits of hepatitis C virus (HCV)eradication for hepatocellular carcinoma (HCC) patients in Barcelona Clinic Liver Cancer (BCLC) stage B/C remain uncertain. METHODS: In this hospital-based cohort study, all HCV-infected patients with BCLC stage B/C HCC during the period January 2017 to March 2021 were retrospectively screened, with 97 patients who had completed direct-acting antiviral (DAA) therapy being enrolled for final analysis. RESULTS: In total, the sustained virological response (SVR) rate was 90.7%. In logistic regression analysis, progressive disease (PD) to prior tumor treatments was significantly associated with SVR failure (odds ratio 5.59, 95% CI 1.30-24.06, p = 0.021). Furthermore, the overall survival (OS) rate was significantly higher in the SVR group than that in the non-SVR group (1-year OS: 87.5% vs. 57.1%, p = 0.001). SVR was found to be an independent factor related to OS (hazard ratio 8.42, 95% CI 2.93-24.19, p = 0.001). However, even upon achieving SVR, the OS rates in BCLC stage C or Child-Pugh stage B patients remained poor. CONCLUSIONS: In BCLC stage B/C HCC, DAA could achieve a high SVR rate except in those patients with PD to prior HCC treatments. SVR was related to improvements in OS; therefore, DAA therapy should be encouraged for patients diagnosed without a short life expectancy.

Glioblastoma (GBM) is the deadliest primary brain tumor and is generally resistant to immunotherapy because of severe dysfunction of T cells. Novel treatment options are critically needed to overcome the immunotherapy resistance of GBM. Here we demonstrate that Zika virus (ZIKV) treatment improves the efficacy of anti-PD ligand 1 (PD-L1) immunotherapy in GBM. We found that ZIKV induces a strong pro-inflammatory response and increases CD4+ and CD8+ T cell intratumoral infiltration and activation in GBM mouse models. ZIKV treatment of mice bearing GBM tumors inhibits tumor growth and prolongs survival. These therapeutic effects of ZIKV on GBM tumors are negated in mice depleted of T cells. Moreover, ZIKV dramatically promotes activation of the type I interferon signaling pathway in GBM cells. ZIKV treatment potently sensitizes GBM to PD-L1 blockade and provides significant and durable survival benefits. Our findings reveal that ZIKV overcomes the resistance of GBM to immune checkpoint blockade, which may lead to therapeutic applications of ZIKV in individuals with GBM receiving immunotherapy.

BACKGROUND: In patients with unresectable hepatocellular carcinoma (HCC), the advances in direct-acting antiviral (DAA) therapy for chronic hepatitis C remain unclear. We aimed to investigate the characteristics of DAA therapy, when compared to interferon (IFN) therapy. METHODS: In this hospital-based study, all HCC patients in Barcelona Clinic Liver Cancer (BCLC) stage B or C, who received pegylated IFN or DAA, were retrospectively screened from 2009 to 2020. Patients without viremia, without HCC, or with HCC in BCLC stage 0, A, or D prior to antiviral therapy were excluded. Rates of and odds ratio (OR) for sustained virological response (SVR) achievement were analyzed. RESULTS: Nineteen and 78 patients were recruited into the IFN and DAA groups, respectively. The median age was significantly older in the DAA group (DAA vs. IFN: 69.5 [25-75% IQR: 62.8-77.3] vs. 64.0 [25-75% IQR: 61.0-68.0]; p < 0.05). The SVR rates were higher in the DAA group as per protocol (DAA vs. IFN: 94.5% vs. 76.5%; p < 0.05) and in BCLC stage B (DAA vs. IFN: 95.2% vs. 76.5%; p < 0.05). All patients in BCLC stage C received DAA therapy, with the SVR rate being 90.9%. In multivariable regression analysis, the 4-week virological response (OR 5.6, 95% CI: 1.3-25.4) and HCC within the up-to-7 criteria (OR 3.7, 95% CI: 1.1-12.9) were independent factors associated with SVR (all p < 0.05). CONCLUSIONS: Compared to IFN therapy, more elderly patients with unresectable HCCs were able to receive DAA therapy, while achieving a significantly higher SVR rate.

Glioma stem-like cells (GSCs) are a subset of tumor cells that initiate malignant growth and promote the therapeutic resistance of glioblastoma, the most lethal primary brain tumor. Ribosome biogenesis is an essential cellular process to maintain cell growth, but its regulatory mechanism in GSCs remains largely unknown. Here, we show that WD repeat domain 12 (WDR12), a component of the Pes1-Bop1 complex (PeBoW), is required for ribosome biogenesis in GSCs. WDR12 is preferentially expressed in GSCs compared to non-stem tumor cells and normal brain cells. High levels of WDR12 are associated with glioblastoma progression and poor prognosis. Silencing WDR12 results in the degradation of PeBoW complex components and prevents the maturation of 28S rRNA, thereby inhibiting ribosome biogenesis in GSCs. Subsequently, WDR12 depletion compromises GSC proliferation, inhibits GSC-derived orthotopic tumor growth, and extends animal survival. Together, our results suggest that WDR12 is crucial for ribosome biogenesis in GSCs, and is thus a potential target for GSC-directed therapy of glioblastoma.

Low levels of reactive oxygen species (ROS) are crucial for maintaining cancer stem cells (CSCs) and their ability to resist therapy, but the ROS regulatory mechanisms in CSCs remains to be explored. Here, we discover that prohibitin (PHB) specifically regulates mitochondrial ROS production in glioma stem-like cells (GSCs) and facilitates GSC radiotherapeutic resistance. We find that PHB is upregulated in GSCs and is associated with malignant gliomas progression and poor prognosis. PHB binds to peroxiredoxin3 (PRDX3), a mitochondrion-specific peroxidase, and stabilizes PRDX3 protein through the ubiquitin-proteasome pathway. Knockout of PHB dramatically elevates ROS levels, thereby inhibiting GSC self-renewal. Importantly, deletion or pharmacological inhibition of PHB potently slows tumor growth and sensitizes tumors to radiotherapy, thus providing significant survival benefits in GSC-derived orthotopic tumors and glioblastoma patient-derived xenografts. These results reveal a selective role of PHB in mitochondrial ROS regulation in GSCs and suggest that targeting PHB improves radiotherapeutic efficacy in glioblastoma.

Type I interferons (IFNs) are known to mediate antineoplastic effects during tumor progression. Type I IFNs can be produced by multiple cell types in the tumor microenvironment; however, the molecular mechanisms by which tumor cells evade the inhibition of immune microenvironment remain unknown. Here we demonstrate that glioma stem-like cells (GSCs) evade type I IFN suppression through downregulation of STAT1 to initiate tumor growth under inhospitable conditions. The downregulation of STAT1 is mediated by MBD3, an epigenetic regulator. MBD3 is preferentially expressed in GSCs and recruits NuRD complex to STAT1 promoter to suppress STAT1 expression by histone deacetylation. Importantly, STAT1 overexpression or MBD3 depletion induces p21 transcription, resensitizes GSCs to IFN suppression, attenuates GSC tumor growth, and prolongs animal survival. Our findings demonstrate that inactivation of STAT1 signaling by MBD3/NuRD provides GSCs with a survival advantage to escape type I IFN suppression, suggesting that targeting MBD3 may represent a promising therapeutic opportunity to compromise GSC tumorigenic potential.

BACKGROUND: Acupoint catgut embedding therapy characterized by acupoint, needle and catgut are superior to traditional acupuncture, due to exerting more comprehensive therapeutic efficacy. However, it is still deficient in clinical evidence for polyglycolic acid sutures, a novel biodegradable material instead of catgut, embedded for the treatment of simple obesity. In our study, we investigate the efficacy and related mechanism of polyglycolic acid sutures embedded in abdominal acupoints on simple obese persons by a randomized control trial. METHODS: A total of 51 eligible participators were randomly allocated to a polyglycolic acid sutures embedding therapy (PASET) group (n = 28) or control group (n = 23). Participators in PASET group received polyglycolic acid sutures alternatively embedded in abdominal I group and II group acupoints in odd and even number therapeutic courses, and participators in control group were required to perform lifestyle modification. The duration of the study was 10 weeks. RESULTS: It suggested that PASET significantly reduced weight, body mass index, hip circumference, waist circumference, waist/hip ratio, waist-to-height ratio and thickness of abdominal subcutaneous fat tissue compared with those before treatment (p < 0.01), but lifestyle modification only illustrated downward trend of weight (p < 0.05). Moreover, PASET group also improved the evaluated scores in aspects of physical function, self-esteem, public distress and sexual life, as well as decreased blood pressure, glycemia, low density lipoprotein, uric acid and the levels of tumor necrosis factor-alpha, interleukin-1ß, and increased high density lipoprotein in comparison with those before treatment (p < 0.05), whose efficacies are superior to control group. Additionally, our results also indicate PASET is relative safe and its pain and discomfort can be tolerable. CONCLUSIONS: PASET distinctly ameliorates anthropometric data and quality of life in obese population, which associates with improvements of metabolic profile and inflammatory response. Based on the advantageous actions, we think PASET is an effective therapeutic approach to simple obesity treatment.Trial registration ChiCTR, ChiCTR1800015591.

Glioblastoma (GBM) is an incurable primary brain tumor that is highly resistant to current treatments. Glioma stem-like cells (GSCs) are an aggressive population of glioma cells that not only initiate malignant growth, but also promote therapeutic resistance. Thus, targeting GSCs is critical for improving GBM treatment and ensuring complete eradication of the tumor. Here, we show that NT5DC2 (5'-Nucleotidase Domain Containing 2), a functionally unknown protein, plays a crucial role in GSC tumor initiation via upregulating Fyn expression. NT5DC2 is preferentially expressed in GSCs relative to the non-stem tumor cells. Knockdown of NT5DC2 significantly inhibits the GSC tumorsphere formation and cell viability in vitro, and tumorigenesis in vivo, thus, prolonging animal survival. Moreover, disruption of NT5DC2 in GSCs markedly reduces the expression of Fyn, a Src family proto-oncogene that has been implicated in the regulation of GBM progression. Importantly, the expression of NT5DC2 strongly correlated with increased aggression of human gliomas, but not that of other brain tumors. Taken together, our results uncover the function of NT5DC2 in GSC maintenance and highlight NT5DC2 as a promising therapeutic target for GBM.

To explore the mechanism of acupoint embedding for obesity based on the western pathological mechanism of chronic low inflammatory response inducing the imbalance between"promoting inflammation"and"anti-inflammation"in immune reaction, and the pathological nature of deficient healthy qi and state of evil domination in the TCM theory induced by the"stagnation heat, phlegm heat, dampness heat, stasis heat"on the basis of qi deficiency. The mechanism may be improving the secretory disorder of adipose tissue and metabolic inflammatory response by the enhanced anti-inflammatory phagocytosis clearance ability in the immune system which is caused by the new inflammatory reaction under the stimulation of innate immune response pattern. The model of"inhibiting chronic low inflammation reaction through the innate immunity"may be an important mechanism of acupoint embedding for obesity.

AIMS: The paucity of data on Type 1 diabetes in China hinders progress in care and policy-making. This study compares Type 1 diabetes care and clinical outcomes in Beijing and Shantou with current clinical guidelines. METHODS: The 3C Study was a cross-sectional study of the clinical practices and outcomes of people with Type 1 diabetes. The study sequentially enrolled 849 participants from hospital records, inpatient wards, and outpatient clinics. Data were collected via face-to-face interviews with patients and health professionals, the Summary of Diabetes Self-Care Activities, medical records, and venous blood samples. Care was audited using ISPAD/IDF indicators. Data underwent descriptive analysis and tests for association. RESULTS: The median age was 22years (IQR=13-34years), and 48.4% of the sample had diabetes less than six years. The median HbA1c was 8.5% (69mmol/mol) (IQR 7.2-10.5%), with significant regional variance (p=0.002). Insulin treatment was predominantly two injections/day (45% of patients). The highest incidence of diabetic ketoacidosis was 14.4 events/100 patient years among adolescents. Of the 57.3% of patients with LDL-C>2.6mmol/L, only 11.2% received treatment. Of the 10.6% considered hypertensive, 47.1% received treatment. Rates of documented screening for retinopathy, nephropathy, and peripheral neuropathy were 35.2%, 42.3%, and 25.0%, respectively. The median number of days of self-monitoring/week was 3.0 (IQR=1.0-7.0). There were significant differences in care practices across regions. CONCLUSIONS: The study documented an overall deficit in care with significant regional differences noted compared to practice guidelines. Modifications to treatment modalities and the structure of care may improve outcomes.

OBJECTIVE: Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) have recently been investigated as two new inflammatory markers used in the assessment of systemic inflammation in many diseases. The purpose of the study was to investigate their relation with disease activity in newly diagnosed SLE patients. METHODS: The study population consisted of 116 SLE patients who did not receive any treatment and 136 healthy controls. We divided the patients into two groups according to the SLE Disease Activity Index 2000 (SLEDAI-2K) system. Group 1 included patients with a score of 9 and lower (patients with mild disease activity), and Group 2 included patients with a score of >9 (patients with severe disease activity). Correlations between NLR, PLR and disease activity were analyzed. RESULTS: The NLR and PLR of SLE patients were significantly higher compared to those of the controls (both P<0.001). There was a statistically significant difference in NLR and PLR between Group 1 and Group 2 (both P<0.05). SLEDAI scores positively correlated with NLR (r=0.312, P<0.001) and PLR (r=0.298, P<0.001). Furthermore, SLE patients with nephritis had higher NLR levels than those without nephritis (P=0.027). Based on the ROC curve, the best NLR cut-off value to predict SLE patients with severe disease activity was 2.26, with 75% sensitivity and 50% specificity, whereas the best PLR cut-off value was 203.85, with 42.3% sensitivity and 83.9% specificity. CONCLUSION: NLR and PLR were two useful inflammatory markers for assessment of disease activity in patients with SLE.

BACKGROUND: Glycaemic control is a great challenge in the management of type 1 diabetes mellitus (T1DM). There is limited data concerning glycaemic control among adults with T1DM. We used data from the Guangdong T1DM Translational Medicine Study to evaluate glycaemic control and its associated factors in Chinese adults with T1DM. METHODS: This cross-sectional analysis included 827 participants who were 18 years of age or older and had been living with T1DM for at least 1 year. Participants with HbA1c levels <7% were compared against those with HbA1c levels ≥ 7%. A multivariate logistic regression model was used to examine factors associated with glycaemic control. RESULTS: Among the 827 participants, the mean age was 34.2 ± 12.1 years and the median (interquartile range) duration of diabetes was 6.1 (3.4, 10.4) years. The median HbA1c level was 8.5% (7.5%, 10.2%). Only one-fifth of participants had HbA1c levels <7%. Insufficient glycaemic control (HbA1c ≥ 7%) was strongly associated with infrequent self-monitoring of blood glucose (OR = 1.21, 95% CI 1.14 ~ 1.29, p = 0.000), high insulin dose (OR = 1.27, 95% CI 1.07 ~ 1.52, p = 0.006), smoking (OR = 3.11, 95% CI 1.44 ~ 6.72, p = 0.004), low-frequency clinical visits (OR = 2.74, 95% CI 1.47 ~ 5.10, p = 0.001), the presence of diabetic autoantibodies (OR = 1.63, 95% CI 1.07 ~ 2.48, p = 0.022) and low fasting C-peptide (FCP) levels (OR = 1.21, 95% CI 1.01 ~ 1.46, p = 0.049) after adjustment for age at disease onset, education level, household income and diet control. CONCLUSIONS: Most adult patients with T1DM did not achieve the HbA1c target. Identifying determinants for glycaemic control provides us valuable information to improve glycaemic control in these patients. Copyright © 2015 John Wiley & Sons, Ltd.

INTRODUCTION: Diabetic retinopathy (DR) is a common chronic microvascular diabetic complication. The presence of DR may indicate microcirculatory dysfunction in other organ systems besides visual morbidity. The objective of this study was to develop a simple diabetic retinopathy risk score to identify DR in Chinese overweight/obese patients with type 2 diabetes mellitus (T2DM). PATIENTS AND METHODS: A multicentre hospital-based cross-sectional study was carried out in Guangdong Province between August 2011 and March 2012. The evaluated 2699 patients included 1263 males and 1436 females, with an average age of 59.4 ± 13.0 years. RESULTS: The diabetic retinopathy risk score was conducted by age, duration of DM, history of antihypertensive drug treatment, and waist circumference. The area under the receiver operating characteristics curve for DR was 0.700 (95% CI 0.671-0.729). Comparing Youden's index of different values, the optimal cut-off point was 20 to predict DR. The odds ratio for one unit increase in the diabetic retinopathy risk score associated with the risk of DR was 1.104 (95% CI 1.089-1.120). CONCLUSIONS: Our data suggest that the diabetic retinopathy risk score could be a reliable primary screening tool for the presence of DR in Chinese overweight/obese patients with T2DM.

BACKGROUND: Type 2 diabetes is often accompanied by altered cardiometabolic risk profiles, including abdominal obesity, hypertension, and dyslipidaemia. The association of altered cardiometabolic risk profiles with chronic complications of diabetes is not well investigated. METHODS: We recruited 2954 type 2 diabetes patients with a body mass index ≥25 kg/m2 who visited the diabetes clinics of 62 hospitals in 21 cities in Guangdong province of China from August 2011 to March 2012. Demographic characteristics, personal and family medical histories, and data on chronic complications of diabetes were collected. Clinical examinations and laboratory assessment were conducted. RESULTS: Abdominal obesity was found in 91.6% of the study population, elevated blood pressure in 78.3%; elevated serum triacylglycerols in 57.8%, and reduced serum HDL-C in 55.9%. Among the cardiometabolic risk factors, elevated blood pressure was significantly associated with almost all the chronic complications of diabetes. After adjusting for age, gender, duration of diabetes, and HbA1c, elevated blood pressure was significantly associated with diabetic retinopathy (OR 1.63, 95% CI: 1.22-2.19), diabetic nephropathy (OR 3.16, 95% CI: 2.25-4.46), cardiovascular disease (OR 2.71, 95% CI: 1.70-4.32), and stroke (OR 1.90, 95% CI: 1.15-3.12). Abdominal adiposity was significantly associated with diabetic nephropathy (OR 1.39, 95% CI: 1.11-1.74). Elevated triacylglycerols was significantly associated with diabetic retinopathy (OR 1.29, 95% CI: 1.05-1.58) and diabetic nephropathy (OR 1.30, 95% CI: 1.05-1.58). Reduced HDL-C was significantly associated with stroke (OR 1.41, 95% CI: 1.05-1.88). CONCLUSIONS: Altered cardiometabolic risk profiles, and elevated blood pressure in particular, were significantly associated with chronic complications in overweight and obese patients with type 2 diabetes. Future studies on the prevention of chronic complications of diabetes might make lowering blood pressure a primary target.

OBJECTIVE: To explore the prevalence and risk factors for dyslipidemia in diabetics with overweight or obesity. METHODS: Diabetics with overweight or obesity were recruited from 62 tertiary and secondary hospitals in Guangdong Province between August 2011 and March 2012. Dyslipidemia was diagnosed as total cholesterol (TC) ≥ 5.7 mmol/L or triglycerides (TG) ≥ 1.7 mmol/L or low-density-lipoprotein cholesterol (LDL-C) ≥ 3.6 mmol/L or high-density-lipoprotein cholesterol (HDL-C) < 1.29 mmol/L in females or HDL-C < 1.03 mmol/L in males. Binary Logistic regression was used to assess the associations between dyslipidemia and associated risk factors. RESULTS: Dyslipidemia was detected in 3160/3593 (87.9%) diabetics with overweight or obesity. And the prevalence of hypertriglyceridemia, low blood HDL-C, hypercholesterolemia and high blood LDL-C was 52.5% (1888/3593) , 54.1% (1945/3593), 33.1% (1188/3593) and 27.4% (985/3593) respectively. Among those with dyslipidemia, patients with simple and mixed dyslipidemia accounted for 34.1% and 53.9% respectively. In binary Logistic regression analysis, the presence of dyslipidemia were associated with female gender (OR = 1.593, 95%CI 1.233-2.057), hemoglobinA1c(HbA1c) (OR = 1.120, 95%CI 1.054-1.191), body mass index (OR = 1.084, 95%CI 1.022-1.150), hypertension (OR = 1.331, 95%CI 1.033-1.714), history of diabetes (OR = 1.586, 95%CI 1.186-2.120) and hyperuricacidemia (OR = 2.270, 95%CI 1.642-3.138). CONCLUSIONS: The prevalence of dyslipidemia is quite high in diabetics with overweight or obesity. The controls of blood pressure, serum uric acid level, blood glucose and body weight may reduce the prevalence of dyslipidemia, prevent and delay the development of cardiovascular complications and reduce the mortality of diabetics with overweight or obesity.

This study investigated the prevalence and determinants of hyperuricemia in Chinese type 2 diabetes mellitus (T2DM) patients with central obesity. A multicentric hospital-based cross-sectional study was carried out in Guangdong Province between August 2011 and March 2012. At each hospital, Chinese T2DM patients with central obesity who were aged over 20 years, whose serum uric acid levels were measured, and who had lived in Guangdong Province for >=1 year, were recruited. Hyperuricemia was defined as serum uric acid >420 µmol/L in men and >360 µmol/L in women. Binary logistic regression was used to assess associated risk factors for hyperu-ricemia. A total of 2,917 T2DM patients with central obesity took part. The overall prevalence of hyperuricemia was 32.6% (36.1% for women, 28.4% for men). Binary logistic regression analyses demonstrated that women (OR: 1.576; 95% confidence interval (CI): 1.231, 2.018), high BMI (OR: 1.228; 95% CI: 1.094, 1.379), waist cir-cumference (OR: 1.135; 95% CI: 1.009, 1.276), hypertension (OR: 1.603; 95% CI: 1.263, 2.035), high total cho-lesterol (OR: 1.133; 95% CI: 1.002, 1.281), triglycerides (OR: 1.134; 95% CI: 1.069, 1.203), low HDL-cholesterol (OR: 0.820; 95% CI: 0.677, 0.995) and low estimated glomerular filtration rate (OR: 0.840; 95% CI: 0.815, 0.866) were risk factors associated with hyperuricemia. Hyperuricemia is prevalent in Chinese T2DM patients with central obesity and is significantly positively associated with women, cardiovascular risk factors such as obesity, hypertension and dyslipidemia, and low eGFR.

OBJECTIVE: To investigate the current situation and influential factors of blood pressure (BP) control in type 2 diabetic patients with overweight or obesity in Guangdong province. METHODS: From August 2011 to March 2012, type 2 diabetic patients with overweight or obesity were recruited from 60 hospitals in 20 cities of Guangdong province, and received standard questionnaires. The conditions of demographic data, clinical examinations, the most recent laboratory assessment, history of disease and drug therapy were recorded. RESULTS: A total of 4029 patients were collected with age of (58.9 ± 12.9) years, and body mass index (BMI) of (27.28 ± 2.76) kg/m². Among the participants, controlled BP was achieved in 23.8% patients. Multiple logistic regression analysis showed that older age, obesity, previous history of hypertension and inadequate glycemic control were the independent factors related to unsatisfactory blood pressure control rate. Among the patients with hypertension, 53.5% took 1 kind of antihypertensive drug, 32.5% took two, and 11.3% took three or more. CONCLUSIONS: Type 2 diabetic patients with overweight or obesity in Guangdong province have poor BP control. Thus, active lifestyle interventions and drug therapy as a comprehensive management way should be taken for the population so as to reduce their cardiovascular events.

OBJECTIVE: To explore the glycemic control status and related risk factors of overweight or obesity patients with type 2 diabetes mellitus (T2DM) in Guangdong province. METHODS: The medical records of overweight or obesity patients with T2DM from 60 tertiary and secondary hospitals in Guangdong Province were collected by questionnaire and physical examination. And the clinical data were analyzed to explore the influencing factors of glycemic control. The HbA1c level was used to assess glycemic control. HbA1c < 7.0% indicated that glycemic control was up to standard. RESULTS: From August 2011 to March 2012, 5241 T2DM patients were recruited. The scope of current analysis was restricted to 4768 subjects with true data and deficiency no more than 5%. There were 2252 males and 2516 females. The age range was from 16 to 90 years, a median age 59.0 (50.0 - 69.0) years, onset age of diabetes 52.0 (44.0 - 60.0) years; a range of disease duration from 1 day to 42 years and a median of 5.0 (2.0 - 11.0) years. The median body mass index was 26.33(24.88 - 28.34) kg/m(2) and median waist circumference 93.0 (88.0 - 100.0) cm. Median HbA1c was 8.1% (6.9% - 10.1%) and only 26.2% patients reached the target level of HbA1c < 7.0%. Influencing factors of poor glycemic control were central obesity, high levels of resting heart rate, concurrent fatty liver and high intensity of treatment. And influencing factors of good glycemic control were regular exercises, smoking cessation, regular glycemic monitoring and good control of total cholesterol/triglyceride. CONCLUSION: A majority of Guangdong type 2 diabetics fail to achieve target values for glycemic control. There is an urgent need for comprehensive management for improving glycemic control.
