OBJECTIVE:To observe the correlation of vitamin D with the incidence of cardiovascular disease and risk factors in elderly patients with type 2 diabetes mellitus. METHODS:94 patients,aged 60 years old above,with type 2 diabetes mellitus were collected retrospectively. Those patients were divided into diabetes group(41 cases)and diabetes complicated with cardiovas-cular disease group(53 cases)according to the condition of disease. 25(OH)D levels and lab indicators of 2 groups were detect-ed. The relationship of cardiovascular lesion with risk factor was analyzed by Multivariate Logistic regression;the correlation be-tween 25(OH)D and risk factors was analyzed by pearson analysis. RESULTS:There was statistical significance in the levels of 25 (OH)D,TC,TG,UA and Ca between diabetes group and diabetes complicated with cardiovascular disease group,with statistical significance(P<0.05). pearson analysis showed that the level of 25(OH)D was negatively related to age,FIB,TC and UA,and positively related to D-dimer and HDL-C,especially correlated with FIB and TC significantly,with statistical significance (P<0.01). Multivariate Logistic regression analysis showed that the deficiency of 25(OH)D was pathogenic factors of type 2 diabetes mellitus. CONCLUSIONS:There is a correlation between the level of 25(OH)D and cardiovascular risk factors as age,FIB,TC, UA,D-dimer,HDL-C. Vitamin D deficiency is the independent risk factors for cardiovascular disease in elderly patients with type 2 diabetes mellitus.

Objective:To observe the influence of different treatment intervals of pulsed dye laser (PDL) in treating hypertrophic scar of burn patients and to explore the optimal treatment interval.Methods:From May 2018 to March 2019 , 20 burn patients who met the inclusion criteria and admitted to the First Affiliated Hospital of Air Force Medical University were included in this prospective randomized controlled study. Patients were divided into 1 week group [4 patients, 2 males and 2 females, aged 27 (4, 67) years,19 scars], 2 weeks group [5 patients, 2 males and 3 females, aged 9 (3, 55) years, 15 scars], 3 weeks group [5 patients, 4 males and 1 female, aged 26 (19, 45) years,15 scars], and 4 weeks group [6 patients, 4 males and 2 females, aged 31 (14, 48) years,13 scars], according to the random number table, and treated with PDL with the treatment intervals of one week, two weeks, three weeks, and four weeks, respectively, and total treatment cycle of 3 months. Before the first treatment and three months after the first treatment, the Vancouver Scar Scale (VSS) was conducted and the decreased value of VSS score was calculated; the laser doppler blood flow meter was used to measure scar blood perfusion and the proportion of change in blood perfusion volume was conducted. Data were statistically analyzed with Kruskal-Wallis test, Wilcoxon rank sum test, Wilcoxon symbolic rank sum test, Bonferroni correction, and Fisher’s exact probability test.Results:The VSS scores of patients in 1 week group, 2 weeks group, 3 weeks group, and 4 weeks group in three months after the first treatment were significantly lower than those before the first treatment ( Z=-3.74, -3.47, -2.69, -3.25, P<0.01). There were no statistically significant differences in the decreased values of VSS scores in three months after the first treatment among the patients in 4 groups ( H=5.18, P>0.05). Three months after the first treatment, the blood perfusion volumes of patients in 2 weeks group and 3 weeks group were significantly lower than those before the first treatment ( Z=-2.95, -2.50, P<0.05). The proportions of changes in blood perfusion volume of patients in the 4 groups were respectively -0.02(-1.05-0.69), -0.29 (-0.75-0.18), -0.11 (-0.55-0.23), 0.05 (-0.61-0.75). There were statistically significant differences among the 4 groups ( H=9.39, P<0.05). The proportions of changes in blood perfusion volume of patients in 2 weeks group was statistically higher than that of 1 week group ( Z=2.76, P<0.01). Conclusions:PDL treatment can reduce the VSS score and blood perfusion volume of scar, the blood perfusion volumes of patients in 2 weeks group and 3 weeks group were significantly decreased, they can be recommended as the appropriate treatment interval of PDL for hypertrophic scar after burn.

In order to assess the effect of long-term versus short-term intravesical chemotherapy in preventing the recurrence of patients with non-muscle-invasive bladder cancer, we searched several databases with words as mesh terms and free text words to find all eligible randomized clinical trials (RCTs) for the comparison of the two strategies of instillation durations. "Observed-Expected events research (O-E)" and "Variance (V)" for calculating hazard ratio (HR) were used in Revman 5.2 software recommended by Cochrane Collabration for data analysis. Sensitivity and subgroup analysis were selected to minish heterogeneity. GRADEpro 3.6 profile recommended by Cochrane Collabration was employed for quality assessment of analyses. Finally, 13 eligible RCTs with 4216 patients were included in this review and 16 comparisons from 13 trials were involved for analysis. The pooled analysis revealed no significant difference between long-term and short-term duration [HR=0.99, 95% CI (0.89, 1.11), P=0.89]. Within the subgroup analysis, patients benefited from long-term instillations with a start regimen of one immediate instillation [HR=0.83, 95% CI (0.69, 1.00), P=0.05]. But patients were not suitable to receive long-term instillations with epirubicin (EPI) [HR=1.01, 95% CI (0.91, 1.13), P=0.78]. The progression rate was not reduced after long-term instillations [HR=0.96, 95% CI (0.66, 1.39), P=0.82]. From our results, patients should not receive introvesical chemotherapy more than half a year. In contrast, patients with one immediate instillation are preferred to have a long-term duration at least one year. Long-term instillations can not reduce the progression rate.

The β-Glucuronidase gene (sbGUS) cDNA firstly from Scutellari abaicalensis leaf was cloned by RT-PCR, with GenBank accession number KR364726. The full length cDNA of sbGUS was 1 584 bp with an open reading frame (ORF), encoding an unstable protein with 527 amino acids. The bioinformatic analysis showed that the sbGUS encoding protein had isoelectric point (pI) of 5.55 and a calculated molecular weight about 58.724 8 kDa, with a transmembrane regions and signal peptide, had conserved domains of glycoside hydrolase super family and unintegrated trans-glycosidase catalytic structure. In the secondary structure, the percentage of alpha helix, extended strand, β-extended and random coil were 25.62%, 28.84%, 13.28% and 32.26%, respectively. The homologous analysis indicated the nucleotide sequence 98.93% similarity and the amino acid sequence 98.29% similarity with S. baicalensis (BAA97804.1), in the nine positions were different. The expression level of sGUS was the highest in root based on a real-time PCR analysis, followed by flower and stem, and the lowest was in stem. The results provide a foundation for exploring the molecular function of sbGUS involved in baicalcin biosynthesis based on synthetic biology approach in S. baicalensis plants.
