Objective To estimate the efficacy and safety of 5-aminolevulinic acid-based photodynamic therapy (ALA-PDT) in the treatment of lichen sclerosus et atrophicus of the vulva.Methods An open and noncontrolled clinical study was performed.Forty-two patients were enrolled in this study and received ALA-PDT once every two weeks for 2 to 4 times.Follow-up visits were arranged at 2,4 and 8 weeks after initiation of treatment,and patients were evaluated at the baseline (before treatment) and all the follow-up time points for the efficacy and safety of treatment.Results Finally,38 patients completed the trial and 4 patients were lost to follow up.The total response rate was 81.6％ (31/38) at the end of the treatment.The average symptom and sign score in these patients was significantly lower at 2,4 and 8 weeks after initiation of treatment than that before treatment (17.6 ± 10.18,11.6 ± 8.35 and 7.6 ± 5.93 vs.29.3 ± 9.17,t =5.26,8.80,12.22,respectively,all P ＜ 0.01).A significant improvement was also observed in the other aspects,such as skin lesion area,hypopigmentation,erosion/rhagades and itching score at 2,4 and 8 weeks,as well as in skin atrophy at 8 weeks after initiation of treatment compared with those before treatment (all P ＜ 0.05).Local burning sensation was the main adverse reaction to ALA-PDT,and 16％ (6/38) of these patients complained of severe pain during the first treatment.Conclusion ALA-PDT shows favorable efficacy in patients with lichen sclerosus et atrophicus of the vulva with a rapid onset of action.

Objective To evaluate the safety and efficacy of recombinant bovine basic fibroblast growth factor in the treatment of corticosteroid-dependent dermatitis.Methods A randomized,double-blind,placebo-controlled clinical trial was carried out.By simple randomization,64 patients with corticosteroid-dependent dermatitis were randomly and equally divided into 2 groups:treatment group topically applying recombinant bovine basic fibroblast growth factor gel twice a day for 4 consecutive weeks,and control group topically applying the gel vehicle twice a day for 4 consecutive weeks.Clinical symptoms and signs were scored before the treatment and after 1-,2-and 4-week treatment.Meanwhile,the water content of the stratum corneum,skin sebum content and transepidermal water loss (TEWL) of the skin lesions were detected.Results Thirty-one patients in the treatment group and 30 in the control group completed the trial.The clinical symptom and sign scores in the treatment group were significantly lower at week 2 and 4 after starting treatment (1.35 ± 0.55 and 1.00 ± 0.45,respectively) than that before treatment (2.77 ± 0.43,both P ＜ 0.05),as well as lower at week 1 (2.06 ± 0.51),2 and 4 after starting treatment than that in the control group (2.43 ± 0.57,2.17 ± 0.53,1.93 ± 0.45,respectively,all P ＜ 0.05).The treatment group showed significantly increased water content of the stratum corneum at week 4 after starting treatment,significantly increased skin sebum content,but decreased TEWL at week 2 and 4 after starting treatment compared with those before treatment (all P ＜ 0.05).Compared with the control group,the treatment group showed significantly higher skin sebum content at week 2 and 4 after starting treatment,higher water content of the stratum corneum,but lower TEWL at week 4 after starting treatment (all P ＜ 0.05).No adverse reactions were observed in either of the 2 groups.Conclusion Recombinant bovine basic fibroblast growth factor is effective and safe for the treatment of corticosteroid-dependent dermatitis,and contributes to repairing and reconstructing the skin barrier function.

Objective To explore the effective evaluation of"internet+iMedLib"health education on pregnant women. Methods Totally 200 pregnant women who established pregnancy care manual and were about to deliver babies in Shaoxing Women&Children's Hospital from June to October in 2016 were selected. The pregnant women were randomized into the experimental group and the control group. The health education model of "internet+iMedLib"were used for the pregnant women of the experimental group, when they established the pregnancy care manual for the first time. Health education prescriptions were handed out, and health related knowledge were communicated face to face for the control group. Finally the experimental group had 96 cases pregnant women, and the control group 94 cases. After delivery, self-care ability, delivery style and satisfaction were investigated and analyzed. Results The scores of pregnant women' s self-care ability in the experimental group were higher than those of the control group (t=2.137-6.155,P < 0.05 or 0.01). The eutocia rate of the experimental group was 81.3%(78/96), higher than that of the control group (63.8%, 60/94) (χ2=7.251, P < 0.01). The average time of nurse's health education in the experimental group were (5.6 ± 1.3) min, less than that of the control group (15.2 ± 1.2) min ( t=-52.863, P<0.01). The satisfaction rate of the experimental group were higher than that of the control group (Z=-6.609, P < 0.05). Conclusions The model of "internet+iMedLib" on pregnant women can not only improve the effect of health education and satisfaction of hospital service, but also they can greatly liberate nurse' s productivity and health education time. The health education model of"internet+iMedLib"is worth being promoted.

ObjectiveTo investigate the prevalence of polycystic ovary syndrome （PCOS） among female college students at a university in Fuzhou City， Jiangxi Province， and to facilitate early detection and intervention of PCOS. MethodsUsing a stratified sampling method， a total of 450 female freshmen were randomly selected for PCOS screening. A self-designed questionnaire was used for data collection， covering menstrual status， high androgen signs， lifestyle， dietary habits， and awareness of PCOS. Sample t test and χ² test were used to compare the basic information and dietary habits between PCOS and non-PCOS cases. The correlation between various indicators and the prevalence of PCOS was analyzed by a logistic regression model. ResultsA total of 12 PCOS cases were identified， with a prevalence rate of 2.99%. PCOS cases exhibited statistically significant differences compared to non-PCOS cases in terms of waist-to-hip ratio， waist circumference， abdominal obesity， the proportion of overweight or obese individuals， and a preference for sweet food （all P<0.05）. Multivariate logistic regression analysis revealed a significant correlation between preference for sweet food and the occurrence of PCOS （OR=4.858， 95%CI=1.199‒19.675，P=0.027）， as well as a significant correlation with PCOS accompanied by abdominal obesity （OR=7.083， 95%CI=0.773‒64.937， P=0.048）. Among the female college students surveyed， 37.90% had never heard of PCOS， 51.62% were only familiar with the name of the disease， and 10.47% had attempted to search for PCOS-related information. ConclusionThe prevalence of PCOS among female college students should not be overlooked and unhealthy dietary habits may be a crucial factor contributing to the occurrence of PCOS during this period. Early screening for PCOS during puberty is crucial.
