ABSTRACT
Objective:To explore the efficacy and safety of microneedle radiofrequency combined with supramolecular salicylic acid in improving facial photoaging.Methods:Thirty patients treated for facial photoaging were randomly divided into the combined treatment group and the microneedle radiofrequency group. All patients were female, aged between 30 and 50 years, with an average age of (39.4±4.1) years. The combined treatment group was treated with microneedle radiofrequency combined with supramolecular salicylic acid, and the Microneedle radiofrequency group was treated with microneedle radiofrequency alone. The patients were followed up 3 days, 7 days, 14 days, 28 days and 3 months after treatment. The results of VISIA, skin physiology and patients' satisfaction were used to compare the two groups of patients after treatment.Results:After 3 months of treatment, the skin pores (11.98±2.14 vs. 15.54±1.52), brown spots (12.40±1.85 vs. 15.84±1.42), ultraviolet spots (6.74±0.87 vs. 11.20±1.70), skin physiological status (transepidermal water loss): 11.84±1.80 vs 13.09±1.96 g/(h·m) 2, stratum corneum water content: 84.91±2.86 % vs 80.29±3.58 %, melanin index: 110.07±15.02 vs. 122.30±9.97, erythema index: 220.43±19.69 vs. 236.30±16.55), elasticity (75.98±3.94 vs. 69.89±3.58), epidermal thickness (1401.33±178.43 vs. 1217.13±139.77), skin color improvement (effective rate 86.7% vs. 40.0%) and patients' satisfaction (total satisfaction was 93.3% vs 67.0%) in the combined treatment group were significantly superior than those in the microneedle radiofrequency group, and the differences were statistically significant ( P<0.05). The reaction of moderate and severe erythema (the incidence rate 40.0% vs. 86.7%) and edema (the incidence rate 26.7% vs. 80.0%) in the combined treatment group was also significantly lower than that in the microneedle radiofrequency group ( P<0.05). No adverse pigmentation was reported in both groups after treatment. Conclusions:The combination of microneedle radiofrequency and supramolecular salicylic acid in the treatment of facial photoaging has definite clinical effect and high safety, which is worthy of clinical application.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the features of oral lesions in patients with human immunodeficiency virus infection/acquired immunodeficiency syndrome (HIV/AIDS).</p><p><b>METHODS</b>A total of 127 HIV-seropositive patients were interviewed for health information and examined for their HIV-related oral lesions according to the EC Clearing House Criteria on Oral Problems related to HIV-Infection (1992). The examinations were conducted by dental specialist and HIV specialist. The CD4 T cell count in peripheral blood of the patients was tested by flow cytometry. The patients were divided into HIV- infected group (42) and AIDS group (85) according to CDC Classification System for HIV- Infected Adults and Adolescents (revised in 1993). Chi-square test was used to test the relationship between systemic disease and oral lesions, and the difference of the prevalence of oral lesions between the two groups.</p><p><b>RESULTS</b>Among the 127 patients, oral candidiasis (51/127), oral hairy leukoplakia (24/127) were common oral manifestation. There was no relationship between the oral manifestation and systemic disease (P = 0.397). The occurrence of oral lesions and oral candidiasis was significantly different between the two groups (χ² = 7.684, P = 0.006; χ² = 14.410, P < 0.001). The CD4 count was related to the prevalence of oral lesions (P = 0.006) and oral candidasis (P = 0.003).</p><p><b>CONCLUSIONS</b>Most oral lesions appeared before the appearance of systemic disease. Oral candidiasis and oral hairy leukoplakia were the most common lesions.Oral lesions had no relationship with systemic disease but could be still an indicator for disease progress.</p>

Objective To evaluate the association between vitamin D deficiency and diabetic nephropathy in type 2 diabetic patients.Methods A total of 594 patients with type 2 diabetes were enrolled from the inpatients of the Nanjing Medical University Affiliated Nanjing Hospital.Fasting serum lipid profile,25-hydroxycalciferol vitamin D and urinary albumin excretion rate were investigated.The relationship between nephropathy and vitamin D deficiency (＜ 20 μg/L) or insufficiency (20-＜ 30 μg/L) was analyzed.Results Nephropathy was found in 177 subjects (29.8％) with albuminuria in 141 and proteinuria in 36 subjects.Vitamin D deficiency was found in 180 subjects and insufficiency in 157 subjects.The proportion of vitamin D deficiency was higher in the individuals with nephropathy than those without nephropathy (36.2％ vs 27.8％,P ＜0.05).The urinary albumin excretion rate was significantly higher in the patients with vitamin D deficiency than those with normal vitamin D concentration [(123.0 ± 299.2)mg/24h vs (47.6 ±97.1) mg/24h,P ＜0.01].The prevalence of nephropathy was higher in the patientswith vitamin D deficiency than those with normal vitamin D concentration (35.6％ vs 26.1％,P ＜ 0.05),while the prevalence of proteinuria was higher in patients with vitamin D deficency (12.2％ vs 3.1％,P ＜0.01).Logistic regression analysis demonstrated that vitamin D deficiency was associated with nephropathy (OR 1.57,95％ CI 1.04-2.37),even after the adjustment for age,gender,hypertension,dyslipidemia,smoking status,use of angiotensin-converting enzyme inhibitors or angiotensin receptor blockers (OR 1.78,95％ CI 1.12-2.81).The Vitamin D concentration was significantly negatively correlated with urinaryalbumin excretion rate (r =-1.783,P ＜ 0.001).Conclusions Type 2 diabetic patients have a high prevalence of vitamin D deficiency.Vitamin D deficiency is independently associated with diabetic nephropathy.
ABSTRACT
Objective To compare the efficacy of insulin aspart and human soluble insulin on postprandial glucose control and blood glucose excursion in type 2 diabetic patients managed with insulin pump therapy. Methods All of 345 hospitalized type 2 diabetic patients were randomized divided into two groups. One group underwent insulin pump therapy with insulin aspart (aspart group, 173 cases),another group with human soluble insulin (humulin R group, 172 cases). Capillary glucose concentrations were measured at 9 time points,including preprandial,2 hours postprandial,bedtime (22:00),midnight(0:00) and 3:00 every day during the treatment. The change of blood glucose at each time point and the variation of postprandial blood glucose excursion was compared between the two groups. The frequency of hypoglycemia was also evaluated. Results After treatment, fasting blood glucose and post breakfast and post dinner blood glucose levels were decreased more significantly in the aspart group than those in the humulin R group. And a significantly smaller postprandial blood glucose excursion was shown in the aspart group compared with that in the humulin R group (P< 0.05). The time to achieve good glycemic control in the aspart group was (4.40 ± 2.16) d, significantly shorter than that in the humulin R group[(5.68 ± 2.29) d](P< 0.05). The incidence of hypoglycemia was significantly lower in the aspart group (P <0.05). Conclusion Insulin aspart results in better control of blood glucose and less glycemic variability compare with human soluble insulin in type 2 diabetic patients during delivery by continuous subcutaneous insulin infusion.
