The different levels and clinical significance of high sensitivity C reactive protein(hs-CRP) , tumor necrosis factor-a ( TNF-α) , erythrocyte sedimentation rate ( ESR) , and urinary monocyte chemoattractant protein-1 (uMCP-1) in 84 type 2 diabetic patients with different urine albumin excretion (UAE) were observed. The results indicated that the levels of hs-CRP,TNF-α,urinary MCP-1 ,and ESR in diabetic patients were significantly higher than those in control group,and the first three indexes increased with the levels of UAE. The results suggest that diabetic nephropathy seems to be correlated with inflammatory reactions.

A total of 185 patients with type 2 diabetes mellitus (T2DM) were consisted of male group (n =95) and postmenopausal female group (n =90).The parameters of fasting plasma glucose,HbA1c,fasting insulin,fasting C peptide,homeostasis model assessment insulin resistant index (HOMA-IR) and β-cell function (HOMA-β),blood lipid,body mass index,and waist to hip ratio were collected and analyzed by Pearson correlation analysis and stepwise multiple regression analysis.The relationships between osteocalcin and these parameters were investigated.The results revealed that osteocalcin was negatively correlated with HbA1C (P＜0.05),and osteocalcin was an independent relevant factor affecting HbA1Clevels.Osteocalcin may be involved in the regulation of glucose metabolism in T2DM.

Objective To investigate the role of Rho/ROCK signaling pathway in the process of human mesangial cells (HMCs) inflammation and fibrosis induced by high glucose. Methods Synchronized HMCs were divided into following groups: ( 1 ) Normal glucose control group ( NG, 5.5 mmol/L glucose); ( 2 ) High glucose group ( HG, 30 mmol/L glucose); (3) Mannitol group( Man,5.5 mmol/L glucose+ 24.5 mmol/L mannitol); (4) NG +Y-27632 group( 10 μ mmol/L Y-27632 ); ( 5 ) HG Y-27632 group ( 10 μmmol/L Y-27632 ). The supernatant and cells were collected at 0,12,24,36,48, and 72 h. Western blot was used to detect the active RhoA and total RhoA,while RhoA, ROCK-Ⅰ, CTGF, and TNF-α mRNA expressions were determined with realtime PGR method in the cells, then ELISA method was used to check protein levels of FN, CTGF, and TNF-α in the supernatant. Results ( 1 ) RhoA activation was stimulated after treatment for with 30 mmol/L glucose, peaked at 1 h, and then decreased ( P = 0. 02). (2) RhoA, ROCK-Ⅰ, CTGF, and TNF-α mRNA expressions in HMC cultured under high glucose were higher than those in the normal group ( P ＜ 0.05 ), and there was certain time-dependence. Besides, there was no statistical significance between Man and NG groups( P＞0. 05 ). ( 3 ) After Y-27632 pretreatment and being cultured with normal glucose and high glucose for24 h or48 h, RhoA, ROCK-Ⅰ, CTGF, and TNF-α mRNA expressions were significantly decreased ( P＜0.01 ) as compared with groups without treatment. (4) High glucose increased FN, CTGF,and TNF-α protein secretion of HMC in a time-dependent manner( P＜0. 05 ). ( 5 ) After Y-27632 pretreatment and being cultured with normal and high glucose for 12,24,36,48,72 h, FN, CTGF, and TNF-α protein secretions were significantly reduced( P＜0.05 ). Conclusion Rho/ROCK signaling pathway may mediate inflammation and fibrosis induced by high glucose in HMCs, supporting a potential role for inhibitors of Rho/ROCK in the treatment of diabetic nephropathy.

Objective:To learn about the current situation of prevention and control results of three-year campaign for Kashin-Beck disease (KBD) in Pingliang City, and to provide scientific basis for prevention and control of KBD.Methods:A retrospective analysis was carried out to collect the KBD surveillance data of all villages in the counties (cities, districts) affected by KBD in Pingliang City, Gansu Province during 2019 - 2020 from the "National Integrated Management System for Endemic Disease Prevention and Control (Three-year Campaign Action Management System)", including, the prevalence of children aged 7 to 12 years old, the implementation of prevention and control measures, and the case investigation, the establishment, management of health files and treatment of current patients.Results:Patients with KBD were distributed in 6 counties (cities, districts), 64 townships (towns), and 690 villages in Pingliang City, and all of them were seriously ill area. In 2019 and 2020, 40 537 and 41 053 children aged 7 to 12 years old were examined, respectively, and the clinical detection rate was 0.08% (31/40 537) and 0.03% (12/41 053), respectively; the X-ray detection rate was 0 in each year. In the dietary structure of residents in Pingliang City from 2018 to 2020, the consumption proportions of rice, flour and other diets was 15.03%, 76.63% and 8.34%, respectively, and the purchase proportion of staple food was 19.28%. From 2018 - 2020, 9 564 households and 36 282 people had been relocated from the affected areas, 4 831 children aged 7 to 12 years old had been raised in different places, 14.81% (420 914/2 842 939) of the original cultivated land had been converted to cash crops, 21.81%(620 045/2 842 939) of the original cultivated land had been converted from farmland to forest (grass), and 231 811 nutrition package for children aged 6 to 24 months had been given. A total of 6 269 KBD patients were investigated and registered, including 3 722 males and 2 547 females, with a gender ratio of 1.00 ∶ 0.68. The most clinical grading was grade Ⅰ, accounting for 78.00% (4 890/6 269), followed by grade Ⅱ (15.89%, 996/6 269) and grade Ⅲ (6.11%, 383/6 269); the age of onset was (64.57 ± 10.01) years old, ranging from 16 to 87 years old; most patients were over 50 years old, accounting for 86.57% (5 427/6 269). In 2019, 1 659 KBD patients were treated. The apparent efficiency, effective efficiency and ineffective efficiency were 25.38% (421 cases), 52.92% (878 cases) and 21.70% (360 cases), respectively. In 2020, 1 395 KBD patients were treated; the apparent efficiency, effective efficiency and ineffective efficiency were 19.50% (272 cases), 61.65% (860 cases) and 18.85% (263 cases), respectively.Conclusions:All villages in KBD area in Pingliang City have reached the elimination standard and achieved the elimination goal. We should continue to do a good job in the dynamic monitoring of the disease, strengthen the implementation of prevention and control measures and rehabilitation intervention for patients with KBD, and improve the quality of life of patients.
