Objective To investigate the clinical efficacy of topical corticosteroids combined with fusidic acid cream in treating infantile eczema.Methods Four hundreds cases of infantile eczema in the outpatient department of our hospital from March 2012 to January 2015 were collected and divided into observation group (220 cases) and control group (180 cases).The observation group received topical corticosteroids combined with fusidic acid cream,while the control group was treated only by topical corticosteroid.The medication time reaching to clinical cure,effect maintenance time during 30 d observation period and recurrence rate were recorded in the two groups.Results During the 30 days of observation, 50 cases of infantile eczema withdrew from the study,17 cases in the observation group and 33 cases in the control group.The average medication time in the observation group was (2.2±0.9)d,which was shorter than (3.2±1.1)d in the control group.The effect maintenance time during observation period in the observation group was (11.7±5.4) d,which was longer than (7.2±4.0)d in the control group,the difference was statistically significant(P<0.05);74.0% of recurrent cases during the observation period in the observation group manifested by mild eczema,while 57.8% in the control group manifested by mild eczema and had no need to use corticosteroid,the improvement of symptoms during recurrent period for the patients in the observation group was better than that for the patients in the control group,the difference was statistically significant (P<0.05).Conclusion Topical corticosteroids combined with fusidic acid cream for treating infantile eczema can reduce the medication time,prolong the effect maintenance time,and alleviate the recurrent symptoms.

Objective To investigate the therapeutic effects of pulsed CO2 laser irradiation in the treatment of syringoma. Methods A retrospective comparison was performed between 28 syringoma patients treated with a pulsed CO2 laser and 30 patients treated with a continuous CO2 laser. The therapeutic effects and treatment complications were compared statistically. Results The treatments were rated effective for all patients in both groups. The outcome was rated " excellent" for 86. 7% of the pulse-treated group and 78. 6% for those treated with continuous las-ing. There was no significant difference between the two groups. There was a significant difference in the rate of pigmentation and atrophic scarring. The pulsed group showed lower levels of both effects than the continuous group. Conclusion The pulsed CO2 laser is a better tool for treating syringoma in terms of safety, efficiency and side effects.

Objective To study the effects of 5-azacytidine’s demethylation for P16 gene on hemangioma cell’s proliferation and apoptosis.Methods Bisulfite sequencing PCR was applied to detect P16 gene′s promoter methylation status in 5-azacytidine treated and untreated EOMA cell line.RT-PCR and western blot were used to detect the P16 gene mRNA and protein expressions.Flow cytometry was used to detect cell proliferation, cell cycle and cell apoptosis.The differences of P16 gene′s promoter methylation status,mRNA and protein expressions,cell proliferation,cell cycle and apoptosis in two groups were compared. Results The methylation rates in 1st and 13th CGs were 0%after 5-azacytidine treatment in EOMA hemangioma cell line,which were lower than in untreated cells.The mRNA and protein expressions increased after 5-azacytidine treatment,which were significantly higher than in untreated cells.The absorbance,S phase and G2/M phase and PI after 5-azacytidine treatment were lower than untreated cells,while the G0/G1 phase and apoptosis rates were higher.Conclusion The P16 gene promoter is hypermethylated in hemangioma cells with silent gene expressions.5-azacytidine could reverse P16 gene′s promoter methylation and silent gene expressions,which inhibit hemangioma cell’s proliferation and promote apoptosis.

Objective To study the effects of Lentinan on bleomycin A5’s inhibition effects in hemangioma-derived endothelial cell. Methods Hemangioma-derived endothelial cell line EOMA were divided into LTN group (only lentinan treatment), BLE group (only bleomycin A 5 treatment), L+B group (Lentinan and bleomycin A5 treatment) and CON group (no lentinan and bleomycin A5 treatment). Cell proliferation, cell cycle, PI and apoptosis were detected and compared among four groups. Results The differences of absorbance in LBE group was significantly higher than that in L+B group after treatment for d 1-d 7 (P<0.05), but both of them were significantly lower than in CON group and LTN group (P<0.05). The G 0/G 1 stage and apoptosis rate in L+B group was significantly higher than in BLE group(P<0.05), while it was significantly lower in S stage, G 2/M stage and PI(P<0.05). Conclusion Lentinan could significantly promote bleomycin A5’s inhibition effects on hemangioma-derived endothelial cell.

Objective:To explore the selection of surgical methods for different sites of symptomatic Rathke's cleft cyst (RCC) and the clinical efficacies of these patients.Methods:Forty-seven patients with symptomatic RCC, admitted to our hospital from January 2016 to December 2019, were chosen in our study; 21 patients with intrasellar symptomatic RCC accepted surgery via unilateral nasal approach at the right side, 19 patients with intra-suprasellar symptomatic RCC accepted surgery via bilateral nasal approach, 3 patients with suprasellar symptomatic RCC accepted endonasal transsphenoidal surgery under endoscope, and 4 patients with suprasellar symptomatic RCC accepted craniotomy via pterion approach. The clinical efficacies and complications of patients accepted different surgical methods were compared. All patients were followed up for 3-36 months to observe the recurrence.Results:The postoperative symptoms of the patients were effectively improved, including headache relief ratio of 27/31, vision loss improvement ratio of 5/5, high prolactin relief ratio of 11/13, pituitary function improvement ratio of 9/18. Complications occurred in 6 patients, presenting as diabetes insipidus. Four patients recurred during follow-up.Conclusion:Intrasellar and intra-suprasellar symptomatic RCC accepted surgery via endoscopic transnasal transsphenoidal approach are safe and effective; selection of surgical methods for suprasellar symptomatic RCC should be determined according to the sizes and growth directions of cysts.
