BACKGROUND:Biological dressing A (porcine Xenoderm) and Physiotule Ag (Coloplast) show good effects on the absorption of exudates, adhesion and anti-bacteria in treatment of degree Ⅱ facial burns. OBJECTIVE:To observe the effectiveness of biological dressing Aversus Physiotule Ag after early debridement of degree Ⅱ facial burns. METHODS:A total of 15 patients with superficial degree Ⅱ facial burn and 10 patients with deep degree Ⅱ facial burns were included. Symmetric facial area of the same patient with the same depth of burn was divided into two parts of same size for treatments. One side was randomly selected as the experimental side, and treated with biological dressing A. The other was selected as the control side and treated with Physiotule Ag. We compared wound healing time, infection, times of changing dressings, skin after healing, drug change comfort and dressing comfort between the two sides. RESULTS AND CONCLUSION:In patients with superficial grade Ⅱ facial burn, times of changing dressings and drug change comfort were better in the experimental side than in the control side (P < 0.05), but the dressing comfort was better in the control side than the experimental side (P< 0.05). No significant difference in wound healing time, infection and skin after healing was detected between the two sides. In patients with deep degree Ⅱ facial burns, wound healing time, times of changing dressings, skin after healing and drug change comfort were better in the experimental side than in the control side (P < 0.05), but the dressing comfort was better in the control side than the experimental side (P< 0.05). No significant difference in infection was detectable between the two sides. Above findings suggested that the therapeutic effects of biological dressing A and Physiotule Ag were similar in treatment of degree Ⅱ facial burns. Biological dressing A in repair of deep degree Ⅱ facial burns promotes the wound healing andelevates the quality of healing.

OBJECTIVEIn order to investigate the potential mechanisms in troglitazone-induced apoptosis in HT29 cells, the effects of PPARγ and POX-induced ROS were explored.

METHODS[3- (4, 5)-dimethylthiazol-2-yl]-2, 5-diphenyltetrazolium bromide (MTT) assay, Annexin V and PI staining using FACS, plasmid transfection, ROS formation detected by DCFH staining, RNA interference, RT-PCR & RT-QPCR, and Western blotting analyses were employed to investigate the apoptotic effect of troglitazone and the potential role of PPARγ pathway and POX-induced ROS formation in HT29 cells.

RESULTSTroglitazone was found to inhibit the growth of HT29 cells by induction of apoptosis. During this process, mitochondria related pathways including ROS formation, POX expression and cytochrome c release increased, which were inhibited by pretreatment with GW9662, a specific antagonist of PPARγ. These results illustrated that POX upregulation and ROS formation in apoptosis induced by troglitazone was modulated in PPARγ-dependent pattern. Furthermore, the inhibition of ROS and apoptosis after POX siRNA used in troglitazone-treated HT29 cells indicated that POX be essential in the ROS formation and PPARγ-dependent apoptosis induced by troglitazone.

CONCLUSIONThe findings from this study showed that troglitazone-induced apoptosis was mediated by POX-induced ROS formation, at least partly, via PPARγ activation.

An aromatase encoded by the CYP19 gene catalyzes the final step in the biosynthesis of estrogens, which is related to endometriosis development. To assess the association of CYP19 gene polymorphisms with the risks of endometriosis, chocolate cysts and endometriosis-related infertility, a case-control study was conducted in Chinese Han women by recruiting 225 healthy control females, 146 patients with endometriosis, 94 endometriosis women with chocolate cyst and 65 women with infertility resulting from endometriosis, as diagnosed by both pathological and laparoscopic findings. Individual genotypes at rs2236722:T>C, rs700518:A>G, rs10046:T>C and [TTTA]n polymorphisms were identified. Allelic and genotypic frequencies were compared between the control group and case groups by chi-square analysis. Odds ratios (ORs) and 95% confidence intervals (95% CIs) were determined by logistic regression analysis to predict the association of CYP19 gene polymorphisms with the risk of endometriosis, the related chocolate cysts and infertility. The genotype distributions of the tested CYP19 gene polymorphisms were not significantly different between the healthy control group and the endometriosis/endometriosis with the chocolate cyst group. However, the CYP19 rs700518AA genotype was significantly associated with an increased risk of endometriosis-related infertility (55.4% in the infertility group vs 25.3% in the control group, P<0.001; OR (95% CI): 3.66 (2.06-6.50)) under the recessive form of the A allele. Therefore, we concluded that in Chinese Han females CYP19 gene polymorphisms are not associated with susceptibility to endometriosis or chocolate cysts, whereas CYP19 rs700518AA genotype confers genetic susceptibility to endometriosis-related infertility.

Objective: To investigate the efficacy and safety of the recombinant human tumor necrosis factor receptor Ⅱ-IgG Fc fusion protein (rhTNFR: Fc, etanercept) for the treatment of occupational medicamentosa-like dermatitis induced by trichloroethylene (OMLDT) . Methods: In September 2011 to February 2016, 12 patients with OMLDT were treated with etanercept 25 mg, subcutaneous injection, twice per week, doubling of first dose. The course of treatment was 6 weeks. The drug eruption area and severity index (DASI) score, the proportion of patients achieving a 50%, 75% and 90% reduction in DASI (DASI50, DASI75, DASI90) and the serum level of TNF-α were used to assess the efficacy at different times. Adverse reactions were also recorded and evaluated. The results were statistically analyzed by nonparametric Friedman test and repetitive measurement ANOVA using the software SPSS19.0. Results: After 4 weeks treatment, the DASI score decreased form 56.33±7.02 to 0.50±0.91 (P<0.01) . The DASI50, DASI75 and DASI90 were all increased to 12 (100%) . The serum level of TNF-α decreased form (43.74±41.62) pg/ml to (3.03±0.47) pg/ml (P<0.01) . Statistically significant difference was observed from the above indexes. There were no adverse reactions in clinical application. Conclusion Recombinant human tumor necrosis factor receptor Ⅱ-IgG Fc fusion protein may be a safe and effective drug in the treatment of OMLDT.

Taiji Quan, as a kind of mild to moderate aerobic exercise, may do benefit in senile hypertension patients.
