Objective:To investigate the level of self-management and daily physical activity in patients with type 2 diabetes mellitus (T2DM) of Zang and Han nationalities in Tibetan, China, and to compare the difference in daily management between T2DM patients of Zang and Han nationalities, to develop reasonable and effective chronic disease management strategies for long-term out-of-hospital management of T2DM patients of Zang nationalities.Methods:A total of 265 T2DM patients with glycosylated hemoglobin (HbA1c) ≥ 7% who were admitted to the Endocrinology Ward of the Hospital of Chengdu Office of People's Government of Tibet Autonomous Region from November 2020 to April 2021 and who were from different regions of Tibet were included in this study according to inclusion and exclusion criteria. The general data of all included patients were collected. Glucose and lipid metabolism-related indicators were determined. The Generalized Diabetes Self-Management Efficacy Scale and International Physical Activity Questionnaires (IPAQ) were used to evaluate patients' levels of self-management and daily physical activity.Results:The hemoglobin level in T2DM patients of Zang nationality was (154.09 ± 24.11) g/L, which was significantly higher than that in T2DM patients of Han nationality ( P < 0.05). The total cholesterol, fasting blood glucose, and low-density lipoprotein in T2DM patients of Zang nationality were (4.63 ± 1.41) mmol/L, (7.94 ± 2.19) mmol/L, and (2.75 ± 1.11) mmol/L, respectively, which significantly higher compared with T2DM patients of Han nationality (all P < 0.05). Compared with T2DM patients of Han nationality, T2DM patients of Zang nationality had lower self-management scores (81.40 ± 15.44) points, diet control scores (17.26 ± 4.97) points, physical exercise scores (11.67 ± 4.42) points, prevention and treatment of high and low blood sugar score (12.21 ± 5.72) points. The differences were statistically significant (all P < 0.05). Moderate-intensity physical activity was a significant difference between T2DM patients of Zang and Han nationalities ( P < 0.05). Conclusion:Compared with T2DM patients of Han nationality, T2DM patients of Zang nationality have lower overall self-management levels, including diet control, physical exercise, prevention and management of high and low blood glucose, and moderate-intensity physical activity. Targeted individualized education should be carried out according to the Tibetan cultural characteristics, to further develop an intervention method and an out-of-hospital management strategy for chronic disease, which are suitable for T2DM patients of Zang nationality.

Objective:To observe the correlation between homocysteine (Hcy) and serum uric acid (SUA) and retinopathy in type 2 diabetes mellitus (T2DM), preliminary study on its predictive value.Methods:A retrospective study. From January 2020 to March 2021, a total of 324 T2DM patients hospitalized in Department of Endocrinology, Cangzhou Central Hospital of Hebei Province were included. Fasting blood glucose (FBG), glycated hemoglobin (HbA1C), triglycerides (TG), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), serum creatinine (Scr), blood urea nitrogen (BUN), Hcy, SUA, peripheral blood endothelial progenitor cells (EPC), circulating endothelial cells (CEC) were counted and homeostasis model assessment for insulin resistance (HOMA-IR) was calculated. According to the absence or presence of diabetic retinopathy (DR), the patients were divided into non DR (NDR) group and DR group with 100 and 214 cases, respectively. Clinical data and laboratory biochemical indexes of the two groups were compared and observed. The logistic regression was used to analyze the independent risk factors for DR in T2DM patients. Smooth curve fitting was used to analyze the curve relationship between Hcy, SUA and DR, and ROC area (AUC) of Hcy, SUA; their combined prediction of DR in T2DM patients was calculated by receiver operating characteristic curve (ROC curve), and the predictive value of Hcy and SUA for DR in T2DM patients was evaluated.Results:Diabetic course ( t=5.380), systolic blood pressure ( t=2.935), hypertension ( χ2=10.248), diabetic nephropathy ( χ2=9.515), diabetic peripheral neuropathy ( χ2=24.501), FBG ( t=3.945), HbA1C ( t=3.336) and TG in DR Group ( t=2.898), LDL-C ( t=3.986), Scr ( t=2.139), SUA ( t=7.138), HOMA-IR ( t=3.237), BUN ( t=3.609), Hcy ( t=2.363) and CEC ( t=19.396) were significantly higher than those in NDR group. The difference was statistically significant ( P<0.05). EPC ( t=9.563) and CPC ( t=7.684) levels were significantly lower than those of NDR group, and the difference was statistically significant ( P<0.05). Logistic regression analysis showed that diabetes course, SBP, hypertension, FBG, HbA1C, LDL-C, SUA, Hcy, EPC, CPC and CEC were all independent risk factors for developing DR in T2DM patients ( P<0.05). The smooth curve fitting analysis showed that Hcy and SUA were positively correlated with the occurrence of DR. After adjusting for confounding factors, when Hcy≥15 μmol/L, the risk of DR Increased by 14% for every 1 μmol/L increase in Hcy [odds ratio ( OR)=0.92, 95% confidence interval ( CI) 0.88-0.98, P<0.05]. When Hcy <15 μmol/L, there was no significant difference ( OR=0.96, 95% CI 0.92-1.08, P>0.05). When SUA≥304 μmol/L, the risk of DR increased by 17%, every 20 μmol/L SUA increased ( OR=0.80, 95% CI 0.68-0.94, P<0.05). When SUA <304 μmol/L, the difference was not statistically significant ( OR=0.83, 95% CI 0.72-0.95, P>0.05). ROC curve analysis results showed that the AUC values of Hcy, SUA and Hcy combined with SUA in predicting the occurrence of DR in T2DM patients were 0.775 (95% CI 0.713-0.837, P<0.001), 0.757 (95% CI 0.680-0.834, P<0.001) and 0.827 (95% CI 0.786-0.868, P<0.001). Hcy combined with SUA showed better predictive efficiency. Conclusions:The abnormal increase of Hcy and SUA levels in T2DM patients are closely related to the occurrence of DR, they are independent risk factors for the occurrence of DR. Hcy combined with SUA has high predictive value for the occurrence of DR.

The positive expression rate of TFF3 was 92.39%, of which the strong positive rate of clinical stage III-IV accounted for 71.79% (42/59) and that of clinical stage I-II was 33.33% (11/33) (P < 0.01). The positive rate of TFF3 was significantly higher in the cases with lymph node metastasis than those without lymph node metastasis (100.00% vs 86.27%, P < 0.05). The AOD value of TFF3 was higher in PTC than in para-carcinoma tissue, that in cases with lymph node metastasis was higher than those without lymph node metastasis, and that in stage III-IV was higher than those in I-II (P < 0.05 or P < 0.05). (2) There was high expression of SDF-1 in the cytoplasm of malignant tissues. The para-carcinoma tissue was weakly positive or negative to SDF 1 and metastatic lymph nodes was weakly positive to SDF 1. The positive rates and AOD values of SDF-1 protein were similar to those of TFF3 in PTC,that is to say the positive rate and AOD values were higher in PTC than in para-carcinoma tissue, those in cases with lymph node metastasis were higher than those without lymph node metastasis, those in stage III-IV were higher than those in I-II, and those in patients older than 45 years old was obviously higher than those in patients under 45 years old (P < 0.05 or P < 0.01); CXCR4 was also mainly expressed in cytoplasm with few expression in nuclei, while negative or weakly positive in para-carcinoma. The positive rate and AOD values of CXCR4 in PTC were similar to SDF-1, meaning that they were higher in PTC than in para-carcinoma tissue and associated with the clinical stage, lymph node metastasis and age (P < 0.05 or P < 0.01). (3) There was positive relationship between TFF3 and SDF-1 as well as between SDF-1 and CXCR4 in PTC (r = 0.971, P < 0.01).@*CONCLUSION@#The high expression of TFF3, SDF-1 and CXCR4 in PTC are correlated with carcinogenesis and progression, and may play a significant role in evaluating the malignancy degree and progression of PTC.

Objective To determine the efficacy of berberine in the treatment of non-alcoholic steatohepatitis ( NASH) , and to investigate the regulating effect on macrophage phenotype transformation in hepatic tissue on methionine -choline deficiency (MCD) diet induced NASH mice.Methods Fourty male C57BL/6 mice were randomly divided into 4 groups (10 mice per group): the normal group (fed with normal diet), the NASH model group (fed with MCD diet), rosiglitazone treatment group (30mg/kg) and berberine treatment group (150mg/kg).Drugs were adopted in the preventive intervention method for 2 weeks.The hepatic histopathological method was adopted to evaluate the drug therapeutic effect.The serum levels of tumor necrosis factor-α(TNF-α), interleukin(IL)-6, and IL-10 were examined with ELISA method.M1 and M2 phenotype were detected by flow cytometry .Results The results showed berberine improved the degree of hepatic histopathology .Berberine not only reduced the level of TNF-α, but also increased the level of IL-10 in serum on NASH mice significantly ( P <0.05 ) . Flow cytometry data indicated that berberine decreased M 1 type macrophages and increased M 2 type macrophages in liver tissue .The ratio of M1/M2 was significantly decreased in berberine and rosiglitazone treated group ( P <0.01 ) .Conclusion Berberine may improve the hepatic pathological process in MCD diet induced NASH model possibly through modulating macrophage phenotype transformation , i.e.The ratio of M2 type is more than M1 type in hepatic tissue , and increasing anti-inflammatory cytokines .
