Surveys of noncommunicable diseases were performed in six communities in Papua New Guinea during 1985-1986. Results are reported here with respect to blood pressure and associated factors in adults. Mean systolic and diastolic blood pressures were lowest, and hypertension was rarest (less than 2%), in three rural/semirural villages on Karkar Island, Madang Province. Intermediate values for blood pressure and moderate prevalence of hypertension (3-6%) were observed in rural and urban Tolai communities in East New Britain Province. A periurban village in the Eastern Highlands Province displayed the highest mean blood pressures and prevalence of hypertension (12% in men and 5% in women). There was a modest rise in mean systolic blood pressure with age in most groups, but the age-related rise in diastolic pressure was much less pronounced. Other cardiovascular risk factors--body mass index (BMI), and plasma cholesterol, glucose and insulin concentrations--were lowest in the least developed rural villages on Karkar Island and highest in the urban Tolai and periurban highland communities. Both systolic and diastolic blood pressures were significantly (and positively) related to age, male sex, BMI and speaking a non-Austronesian language. It is concluded that there is now a considerable variation in the prevalence of hypertension, and the levels of blood pressure and other cardiovascular risk factors, in different communities in Papua New Guinea.

Objective:
To investigate the prevalence of erectile dysfunction (ED) in men with pre-diabetes.
METHODS:
This study included 500 men with impaired fasting glycaemia (IFG), 500 with impaired glucose tolerance (IGT), and another 500 with normal blood glucose (NBG), all from Lanzhou. We conducted a questionnaire investigation among the subjects using the International Index of Erectile Dysfunction 5 (IIEF-5).
RESULTS:
The prevalence rates of ED in the IFG, IGT, and NBG groups were 14.8%, 29.2%, and 33.2%, respectively. After controlling for age, nationality, occupation, education, income, obesity, and blood pressure, the incidence rate was markedly higher in the IFG and IGT than in the NBG group (29.2% and 33.2% vs 14.8%, P <0.05), but showed no statistically significant difference between the IFG and IGT groups (P >0.05).
CONCLUSIONS
The prevalence of ED is higher in men with pre-diabetes than in those with normal blood glucose in Lanzhou.

BACKGROUNDSeveral previous studies have shown that snoring is associated with glucose metabolism and the development of diabetes, but rare study has shown the association between snoring frequency and prediabetes, particularly in China. We hypothesized that individuals who snore might have a higher risk of prediabetes. This study aimed to investigate the association between self-reported snoring and prediabetes in a Chinese population.
METHODSA cross-sectional study was performed in three large communities of Beijing from December 2011 to August 2012 by recruiting individuals aged ≥40 years old. All participants were requested to complete a detailed questionnaire and undergo anthropometric measurements. A 75 g oral glucose tolerance test was performed in individuals without diabetes. Blood samples of all participants were collected; blood glucose and blood fat levels were measured. Multivariate logistic regression models were built to assess the association between snoring frequency and prediabetes.
RESULTSA total of 13,592 participants (female: 66.56%; mean age: 56.8 ± 7.9 years; mean body mass index: 25.5 ± 3.4 kg/m2) were included in the final analysis. Of these, 30.9% were diagnosed with prediabetes, while 41.3% and 25.4% had occasional and habitual snoring, respectively. Habitual snoring was associated with an increased risk of prediabetes (odds ratio [OR]: 1.3, 95% confidence interval [CI]: 1.1-1.4, P< 0.001), after adjusting for diabetes and sleep-related confounders in the multivariable models. Habitual snoring was also associated with isolated impaired fasting glucose (IFG; OR: 1.3, 95% CI: 1.0-1.6; P< 0.001) and isolated impaired glucose tolerance (IGT; OR: 1.3, 95% CI: 1.2-1.5; P< 0.001), but not IFG + IGT (OR: 1.1, 95% CI: 0.9-1.4; P = 0.281). When stratified by total cholesterol (TC) levels, this association between habitual snoring and prediabetes was observed only in individuals with TC <5.6 mmol/L (OR: 1.4, 95% CI: 1.2-1.6; P< 0.001).
CONCLUSIONSHabitual snoring is associated with prediabetes, but only in individuals with TC <5.6 mmol/L. Further prospective studies are needed to confirm this finding.

The data of 1,265 in-patients with diabetic ketosis or ketoacidosis treated in West China Hospital from October 2005 to October 2011 were analyzed retrospectively, and 8 of whom met fulminant type 1 diabetes (F1D) diagnostic criteria. The clinical features of the 8 F1D patients were investigated and compared with other 16 newly diagnosed autoimmune type 1 diabetes (T1D) patients, gender- and age-matched and with acute onset of ketoacidosis. During the six years between 2005 and 2011, the incidence of FID was 6.3 per thousand (8/T265) among all patients with diabetic ketosis or ketoacidosis admitted to the West China Hospital. The averaged age of the patients at onset of F1D was (30. 1 +/- 9. 7) years old, and the duration of diabetes was (4. 0 +/- 2. 4) days. Five of the 8 F1D patients had flu-like symptoms, and 7 had gastrointestinal symptoms. Blood glucose of F1D patients on admission was significantly higher than that of autoimmune T1D patients (P<0. 01), while the glycated hemoglobin (HbAlc) was lower than that of autoimmune T1D patients (P<0. 01). Additionally, fasting and postprandial C-peptide was significantly lower in F1D patients, with more severe acidosis, electrolytes and acid-base disturbances. The data suggest, that, compared with the autoimmune T1D patients, F1D patients have more complicated and more severe clinical manifestation with more severe hyperglycemia, more significant insulin deficiency and more obvious fluid electrolytes and acid-base disturbances. However, the sensitivity and the specificity of the diagnostic criteria of F1D are still needed to be improved for the Chinese people, so more multi-center and large-scale clinical trials should be conducted in the future.

OBJECTIVETo study the clinical features of liver disease patients with abnormal glucose metabolism.
METHODSLiver functions and levels of FPG, PPG, FINS, PINS, FCP, and PCP in 91 chronic hepatitis B patients with abnormal glucose metabolism (62 had liver cirrhosis) were analyzed.
RESULTS(1) The incidence of hepatogenic impaired glucose tolerance (IGT) and of diabetes mellitus (DM) in hepatitis B patients with liver cirrhosis (20.53%; 24.11%) were higher than those without cirrhosis (3.82%; 1.64%; P<0.05, P<0.01). (2) There were no diabetic symptoms among any of the hepatogenic IGT and DM patients. 12 of 19 chronic hepatitis B patients with primary DM and 6 of 12 hepatitis B associated liver cirrhosis patients with primary DM had diabetic symptoms. (3) The levels of FPG and PPG in chronic hepatitis B patients with hepatogenic IGT and DM were lower than those in the patients with primary DM (P<0.05), but the levels of PINS and PCP in chronic hepatitis B patients with hepatogenic IGT and DM were higher than those in the patients with primary DM (P<0.05). (4) There were no differences in the levels of FPG and PPG between the hepatitis B associated liver cirrhosis patients with hepatogenic DM and those with primary DM (P<0.05). The levels of FINS, PINS, FCP, and PCP were higher in the hepatitis B associated liver cirrhosis patients with hepatogenic DM than those in the hepatitis B associated liver cirrhosis patients with primary DM (P<0.05). The levels of FPG and PPG in the hepatogenic DM patients were higher than those in the hepatogenic IGT patients (P<0.05), but their levels of FINS, PINS, FCP and PCP were lower than those in the hepatogenic IGT patients (P<0.05, P<0.01).
CONCLUSIONHepatogenic IGT and DM are always secondary in severe liver cirrhosis patients, who always showed no diabetic symptoms. The chronic hepatitis B patients with hepatogenic DM had increased insulin secretion, while the hepatitis B associated liver cirrhosis patients with hepatogenic DM had decreased insulin secretion.

OBJECTIVETo determine whether smoking increases the risk for developing metabolic syndrome (MetS) in Chinese men.
METHODSA total of 693 men with no MetS at baseline were followed for 2.9-5.5 years. Subjects were divided into nonsmokers, ex-smokers, and current smokers according to baseline smoking status.
RESULTSAfter adjusting for age, education level, alcohol intake, fasting plasma insulin, HOMA-IR index, and BMI at baseline and weight change, current smokers were dose-dependently associated with increased risk for developing new MetS compared with nonsmokers. The odds ratio (OR) was 2.131 (95% CI, 1.264, 3.592; P<0.01) for the NCEPIII definition or 3.083 (95% CI, 1.807, 5.295; P<0.01) for the JCDCG definition of MetS. Ex-smokers who had quit for ≥13 years significantly decreased the risk for developing new MetS defined by the JCDCG definition. Compared with nonsmokers, current smokers were significantly associated with increased incidence of hypertriglyceridemia and low HDL-C.
CONCLUSIONSmoking is a risk factor for developing MetS in Chinese men after adjusting for age, education level, alcohol intake, fasting plasma insulin, HOMA-IR, BMI, and weight change. This could be due to an increased incidence of dyslipidemia. Smoking cessation for >13 years decreased the risk for developing MetS defined by the JCDCG definition.

8.Effect of diabetes mellitus on the development of radiation pneumonitis in patients with non-small cell lung cancer.
Chinese Journal of Oncology 2009;31(1):45-47
OBJECTIVEThe purpose of this study was to investigate whether the associated diabetes mellitus exerts a certain effect on the development of radiation pneumonitis in patients with non-small cell lung cancer.
METHODS156 patients with non small cell lung cancer were treated with three-dimensional conformal radiation therapy in this study, including 52 associated with diabetes and 104 non-diabetic patients as a control group. All the patients were followed up for one year and the development of radiation pneumonitis was observed. Radiation pneumonitis was diagnosed according to the criteria of radiation therapy oncology group. The morbidities of radiation pneumonitis in the two groups were compared. The relationships between the morbidity of radiation pneumonitis and blood sugar level as well as diabetic history were analyzed by chi-square test.
RESULTSTwenty-one (40.4%) of 52 patients with diabetes had radiation pneumonitis (grade 2 or greater), while in the control group only 22 of 104 patients (21.2%) suffered from radiation pneumonitis. There was a statistically significant difference between the two groups in the morbidity of the radiation pneumonitis (P < 0.05), with a relative risk value of 2.05 (95% CI, 1.17, 3.58). The rate of the radiation pneumonitis in the patients with a lower blood sugar level (< 7 mmol/L) was significantly lower than that in those with a higher blood sugar level (30.6% vs. 62.5%, P < 0.05). However, the rate of radiation pneumonitis in the patients with a longer diabetic history was not significantly different from that in those with a shorter diabetic history (P > 0.05).
CONCLUSIONNon-small cell lung cancer patients with diabetes mellitus are more vulnerable than those without to radiation pneumonitis. Therefore, diabetes mellitus is a newly discovered risk factor to radiation pneumonitis, and the blood sugar level is positively correlated with the morbidity of radiation pneumonitis.

OBJECTIVETo explore the risk factors and the main TCM syndrome types associated with the diabetes mellitus type 2 (DM2) patients complicated with non-alcoholic fatty liver (FL).
METHODSAdopted controlled trial method, the age, stature, body weight, and body mass index (BMI) of 180 DM2 patients were compared with those complicated with or without FL. And some related laboratory indexes, including the age, stature, body weight, BMI, fasting blood glucose (FBG), C-peptide (CP), glycosylated hemoglobin (HbA1c), triglyceride (TG), total cholesterol (TC), high and low density lipoprotein cholesterol (HDL-C and LDL-C), and 2 h post-prandial CP (2 h CP), were compared as well. Moreover, patients' TCM syndrome types were classified.
RESULTSNo significant differences were found between DM2 patients complicated with or without FL in aspects of FBG, HbA1c, TC, LDL-C and age, stature (P > 0.05), but significant difference did show between them in aspects of CP (4.09 +/- 2.40 microg/L vs 2.47 +/- 1.74 microg/L), 2h CP (6.38 +/- 5.46 microg/L vs 4.35 +/- 2.92 microg/L), TG (2.81 +/- 2.33 mmol/L vs 1.93 +/- 1.92 mmol/L), HDL-C (1.07 +/- 0.06 mmol/L vs 1.19 +/- 0.32 mmol/L) as well as in body weight (73.4 +/- 11.7 kg vs 61.4 +/- 10.1 kg) and BMI (26.0 +/- 3.67 vs 22.8 +/- 3.23), respectively (P < 0.05 or P < 0.01). Moreover, phlegm-dampness type was more liable to appear in DM2 patients complicated FL.
CONCLUSIONSObesity, insulin resistance and lipid metabolism disorder are the chief risk factors in DM2 patients complicated with FL and phlegm-dampness is the chief pathogenesis.

INTRODUCTIONThere is limited evidence about the association between smoking and metabolic syndrome (MS). The aim of this study was to assess the association of smoking with MS components.
MATERIALS AND METHODSAs part of the baseline survey of a community-based study, we studied 5,573 non-diabetic men. All participants were interviewed and underwent physical examinations and blood collection.
RESULTSThe study participants comprised 1,625 smokers and 3,948 non-smokers, with a mean age of 38.07 +/- 14.85 years. Serum low-density lipoprotein-cholesterol (LDL-C) and triglycerides (TG) were higher in smokers than in non-smokers (LDLC: 115.34 +/- 39.03 vs 112.65 +/- 40.94 mg/dL, respectively, P = 0.015 and TG: 175.13 +/- 102.05 vs 172.32 +/- 116.83 mg/dL, respectively, P = 0.005). Body mass index, waist circumference and waist-hip ratio were lower in smokers than in non-smokers. Mean systolic and diastolic blood pressures were significantly lower in smokers than in non-smokers (systolic: 112.06 +/- 15.888 vs 117.25 +/- 17.745 mmHg, respectively, P = 0.000; diastolic: 73.66 +/- 10.084 vs 76.23 +/- 10.458 mmHg, respectively, P = 0.000). The percentage of individuals with 2 MS components was higher in smokers than in non-smokers (39.64% vs 33.00%, respectively, P = 0.000). However, the percentage of non-smokers with 3 MS components was higher than in smokers (49.62 % vs 43.82%, respectively, P = 0.000).
CONCLUSIONSOur findings support the hypothesis that lifestyle factors such as smoking can adversely affect MS components. However, we should acknowledge that these differences may have resulted from the large sample sizes studied and may not be clinically significant. The lower prevalence of some MS components in smokers than in nonsmokers might be because of their lower anthropometric measures.
