Objective To explore the correlation between Triglyceride (TG), high density lipoprotein cholesterol (HDL-C), total cholesterol (TC) and diabetic Peripheral neuropathy, and to provide a clinical basis for the diagnosis of diabetic peripheral neuropathy. Methods A total of 48 patients with diabetic peripheral neuropathy diagnosed in our hospital from January 2017 to January 2018 were retrospectively analyzed and enrolled into the DPN group. Another 48 patients with type 2 diabetes admitted to our hospital during the same period were included in the T2DM group. The differences of triglyceride (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C),low density lipoprotein cholesterol (LDL-C),and apolipoprotein B (ApoB) between the two groups were analyzed. And the correlation between these indicators and diabetic peripheral neuropathy were analyzed by logistic regression equation. Results The levels of TG, TC, LDL-C and ApoB in the DPN group were significantly higher than those in the T2DM group, and HDL-C was significantly lower in the DPN group than that in the T2DM group (P<0.05). Logistic regression equation analysis showed that TG, TC, and HDL-C, LDL-C, ApoB were risk factors for the onset of DPN (P<0.05). Conclusion The level of blood lipids in patients with diabetic peripheral neuropathy is higher than that in patients with diabetes alone. The levels of TG, TC and HDL-C,LDL-C, ApoB are closely related to the pathogenesis of DPN, which are important factors leading to neuromicrovascular disease.

Continuing advances in dentin bonding technology and adhesives revolutionized bonding of resin-based composite restorations. However, hybrid layers created by contemporary dentin adhesives present imperfect durability, and degradation of collagen matrix by endogenous enzymes is a significant factor causing destruction of hybrid layers. Bond durability can be improved by using enzyme inhibitors to prevent collagen degradation and to preserve integrity of collagen matrix. This review summarizes progress on matrix metalloproteinase inhibitors (including chlorhexidine, ethylenediaminetetraacetic acid, quaternary ammonium salt, tetracycline and its derivatives, hydroxamic acid inhibitors, bisphosphonate derivative, and cross-linking agents) and suggests prospects for these compounds.

Pulmonary hypertension has a high mortality rate,and although targeted therapy is available,it is still incurable,and the long-term prognosis for patients is poor.As a tyrosine kinase inhibitor,imatinib was approved for marketing in China in 2002 for the treatment of chronic myelogenous leukemia and other tumor diseases.In addition to the antitumor effects,imatinib was found to improve hemodynamics and exercise tolerance in patients with severe pulmonary arterial hypertension,but the safety was suboptimal.With the emergence of new formulations of imatinib targeted at the lungs,it is expected to become a new targeted drug for pulmonary arterial hypertension.

Objective:To evaluate the applicability of the Zhang′s diagnostic criteria for atopic dermatitis (AD) in adolescents and adults from southern Jiangsu.Methods:A total of 1 769 patients were collected, who were newly diagnosed with eczema or AD in departments of dermatology of 7 hospitals in southern Jiangsu from May 2019 to May 2021. A standardized survey interview was conducted with patients by dermatologists using a self-designed questionnaire, which included patient′s personal information, relevant medical history, clinical characteristics, laboratory tests, etc. Using Hanifin-Rajka criteria as the gold standard, the sensitivity and specificity of the Williams criteria, Zhang′s criteria and Japanese Dermatological Association (JDA) criteria were evaluated, separately.Results:Among the 1 769 patients, there were 759 (42.9%) males and 1 010 (57.1%) females, aged 32.2 ± 8.2 years (range, 12 - 79 years) . Pruritus was the most common clinical feature among the AD patients (883/913, 96.7%) . When using the Hanifin-Rajka criteria as the gold standard, 913 (51.6%) subjects were diagnosed with AD; the sensitivity of Zhang′s criteria reached 92.6% (845/913) , and its specificity was 73.2% (627/856) ; the sensitivity of Williams′ criteria was 87.8% (802/913) , and its specificity was 81.3% (696/856) ; the sensitivity of JDA criteria reached 96.9% (885/913) , and its specificity was 68.9% (590/856) . The consistency in the diagnosis of AD was moderate between the Zhang′s criteria and Williams criteria (Kappa = 0.61, P = 0.009) , was relatively high between the Zhang′s criteria and JDA criteria (Kappa = 0.85, P = 0.001) , and was moderate between the Williams criteria and JDA criteria (Kappa = 0.51, P = 0.013) . Conclusions:Compared with the Hanifin-Rajka criteria, the Zhang′s criteria exhibit good sensitivity and specificity for the diagnosis of AD among adolescents and adults in southern Jiangsu. However, pruritus remains important for the diagnosis of AD.
