Objective To investigate the relationship between Helicobacter prlori (Hp) infection and type 2 diabetes related complications.Methods Eighty-five patients with type 2 diabetes had been tested and divided into Hp negative group (42 cases) and Hp positive group (43 cases),the triglyceride (TG),low density lipoprotein cholesterol (LDL-C),fasting plasma glucose (FPG),glycosylated hemoglobin (HbA1c),tumor necrosis factor-α (TNF-α) and complications occurred were compared between two groups.Results The TG,LDL-C,FPG,HbA1c and TNF-α in Hp positive group was significantly higher than that in Hp negative group [(4.83 ± 0.95) mmol/L vs.(3.03 ± 0.75) mmol/L,(4.99 ± 0.96) mmol/L vs.(3.91 ±0.87)mmol/L,(10.85 ±2.97) mmol/L vs.(8.11 ±2.69) mmol/L,(9.35 ± 1.96)％ vs.(7.08 ± 1.53)％,(7.33 ± 0.78) ng/L vs.(3.65 ± 0.98) ng/L] (P＜ 0.01).The cardiovascular disease,cerebrovascular disease,kidney disease,retinal changes and podiatric complication rate in Hp positive group was 51.16％ (22/43),37.21％(16/43),27.91％(12/43),34.88％(15/43),23.26％(10/43),significantly higher than that in Hp negative group [28.57％ (12/42),16.67％ (7/42),9.52％ (4/42),14.29％ (6/42),7.14％ (3/42)],there was significant difference between two groups (P ＜ 0.05).Conclusion Type 2 diabetes Hp infection can make the higher TG,LDL-C,FPG,HbA1c,TNF-α and can increase the risk of diabetes complications.

The three‐dimensional digital substraction angiography (3D‐DSA) significantly elevated detection rate of intracranial small vessel aneurysms in recent years .It has become the novel gold standard diagnosing antracranial small vessel aneurysms .The present article made a review on 3D‐DSA value for diagnosis ,treatment and prognostic assessment of intracranial small vessel aneurysms .

As a new technique ,CT spectral imaging can obtain two images of different energy level at same phase simultaneously ,then immediately rebuild high definition monoenergetic images ranging from 40 kV to 140 kV .It provides reliable data and information for early qualitative and quantitative diagnosis of diseases ,which possess huge potential in clinical and science research ;and more extensive developing space for developing of scientific research and clinical application .

Objective: To investigate the relationship between total homocysteine (tHcy) levels and sarcopenia among the elderly, so as to provide insights into the prevention and treatment of sarcopenia. Methods: The elderly aged 65 years and older who participated in the physical examination of Shibantan Township Health Center in Xindu District, Chengdu City from April to June 2021 was selected as the study subjects. The elderly with sarcopenia (diagnosed according to the diagnostic criteria of the Asian Sarcopenia Working Group in 2019) and non-sarcopenia were matched 1︰1 by gender and age (±2 years). Demographic information, skeletal muscle mass, skeletal muscle strength and tHcy were collected through questionnaire surveys, physical examination and laboratory testing. Multivariable conditional logistic regression model was used to explore the relationship between tHcy and sarcopenia. Results: A total of 320 individuals, including 160 sarcopenia patients and 160 non-sarcopenia individuals, were investigated. There were 138 males (43.13%) and 182 females (56.87%), with a median age of 71.00 (interquartile range, 6.00) years. There were 57 drinkers (17.81%), 78 smokers (24.37%), 173 cases of hypertension (54.06%) and 124 cases of hyperhomocysteinemia (38.80%). Multivariable conditional logistic regression analysis showed that elevated tHcy was associated with an increased risk of sarcopenia (OR=1.107, 95%CI: 1.024-1.197), after adjusting for smoking, alcohol consumption, hypertension, waist circumference, neck circumference, body mass index, platelet count and high density lipoprotein cholesterol. Conclusion Elevated tHcy is associated with sarcopenia, and intervention should be carried out for the elderly with higher tHcy.
