BACKGROUND: An antibiotic-free, fixed-dose combination gel with adapalene (A) 0.1% and benzoyl peroxide (BPO) 2.5% has been developed for treatment of acne vulgaris. OBJECTIVE: To compare the clinical outcomes of A-BPO combination gel with vehicle gel for treatment or maintenance therapy of patients with acne vulgaris. METHODS: An electronic search of the database PubMed (1966 to September 2012), Embase (1984 to September 2012), and Cochrane Controlled Trials Register (CENTRAL; 3rd Quarter, 2012) was undertaken to identify relevant studies. Main clinical outcomes were success rate, treatment-related adverse events (AEs), AEs leading to discontinuation, satisfaction with the effectiveness, and overall satisfaction. RESULTS: Six studies were finally included in this meta-analysis. The A-BPO group yielded better clinical outcomes regarding the success rate (p<0.00001), satisfaction with the effectiveness of treatment (p=0.005), and overall satisfaction (p=0.005) compared to the vehicle group. The incidence of treatment-related AEs in the A-BPO group was comparable with that of vehicle group (p=0.09), while the A-BPO group was associated with a slightly increase in the incidence of AEs leading to discontinuation when compared with the vehicle group (p=0.02). CONCLUSION: A-BPO combination gel yields better clinical outcomes including success rate, satisfaction with the effectiveness, and overall satisfaction compared to vehicle gel, despite an increased incidence of AEs leading to discontinuation. The A-BPO combination agent most likely contributes to the treatment of moderate acne vulgaris rather than severe acne vulgaris, but it may be useful in maintenance therapy of patients with severe acne vulgaris.

Objective To explore the effects of vinblastine on abcb4 tumor resistance gene expression in early development zebrafish and lay an important foundation for multi-drug resistant antineoplastic screening in zebrafish model.Methods Zebrafish embryos of 0.5~1.5 hours post-fertilization were exposured to different concentrations of vinblastine, and then calculated the IC50 of vinblastine.Zebrafish embryos of 0.5~1.5 hours post-fertilization were treated with different concentrations of vinblastine and embryo culture medium respectively, and then observed zebrafish embryo development in 24~120 hours post-fertilization and recorded the number of death, hatch and malformation.Evaluating the impact of vinblastine on abcb4 gene expression in zebrafish with quantitative real-time PCR and whole-mount in situ hybridization by collecting zebrafish embryos exposed to different concentrationsof vinblastine.Results Vinblastine IC50 in zebrafish embryos was 3.08 μmol/L.The mRNA level of abcb4 gene in vinblastine treated embryos was significantly increased compared to blank control group.Moreover, abcb4 gene positive hybridization signals were found in the small intestine of zebrafish embryos after 120 hours post-fertilization and also found in the brain and heart of zebrafish embryos by the method of whole-mount in situ hybridization.Conclusions Vinblastine can significantly increase the expression level of abcb4 tumor resistancegene in early development zebrafish embryos, which indicates that zebrafish can be used as a tumor resistant drug screening model.

Objective To observe expression of resistin gene in adipose tissue of SD rats fed with high-fat diet and its correlation to insulin resistance, diabetes mellitus and leptin. Methods Using RT-PCR to mRNA from adipose tissue, the products were obtained, purified, constructed and squenced. Once its squence was verified, semi-quantitative RT-PCR and Northern Blot were employed to study its expressions in adipose tissues of rats with different diets. Oral glucose tolerance test and insulin release test were performed in 2 groups of rats. Results (1) The resistin gene was successfully constructed and sequenced, which was in accordance with the data of genbank. (2) Compared with the control, the expression of resistin in adipose tissue of high-fat diet rats was significantly enhanced, and blood glucose, serum insulin and leptin levels were also elevated in high-fat diet rats (P

Objective To observe the effect of berberine on glucose transport in 3T3-L1 adipocytes and to investigate its mechanism. Methods The glucose consumption of the cells was determined by the glucose oxidase method. The glucose transportation rate of the cells was assayed by the uptake of 2-deoxy-〔 3H〕-D-glucose. Protein kinase B (Akt) activity was detected by immunoprecipitation and Western blot. The gene expression of c-Cbl-associated protein (CAP) was detected by Northern blot. Results 0.1～200 ?mol/L berberine significantly increased glucose consumption in 3T3-L1 adipocytes with a dose-dependent effect, which was independent of insulin. The glucose transportation was significantly increased in adipocytes incubated with 0.1～10 ?mol/L berberine; the action began at 2 h and reached a peak value at 12 h. The results of immunoprecipitation and Western blot showed that berberine did not enhance Akt activity. The result of Northern blot indicated that berberine significantly decreased CAP mRNA expression. Conclusion Adipocytes are the important target cells of berberine. Berberine significantly increases glucose transportation and consumption in adipocytes, the action appeares to be independent of insulin signal pathway.

Objective: To explore the influence of adverse childhood experiences (ACEs) on pubertal development of boys and girls and to provide a reference for the development of intervention measures. Methods: A stratified cluster sampling method was used to select a total of 1 156 students in grades three and four in the boarding school system and public primary schools in Huangshan City and surrounding towns in September 2018, using the Childhood Trauma Questionnaire (CTQ) and the Pubertal Development Scale (PDS). For the baseline self-assessment survey, according to different dimensions, abuse children score no exposure groups. Children were divided into an exposure group and a high exposure level group, according to their childhood experiences. PDS self-report questionnaire was administered two years later, and an analysis of ACE type and severity of the continuous impact of youth development was conducted. Results: In the baseline survey, there were 53 girls (11.32%) and 51 boys (7.41%) who developed earlier. The rate of early development in girls was higher than that of boys, and the difference was statistically significant(χ 2=5.21, P<0.05). Univariate analysis showed gender differences in the effects of type and severity of ACEs and abuse on adolescent development at both baseline and follow-up. There were gender differences in the rate of early development between boys and girls at baseline and at follow-up between the exposure groups. Regression analysis showed that the higher the degree of emotional abuse, emotional neglect, and sexual abuse in girls, the higher the PDS score(B=0.22, 0.15, 0.08, P<0.05). In boys, the more severe the emotional abuse experienced, the higher the PDS score, and the more severe the physical abuse experienced, the lower the PDS score(B=0.20, 0.04, P<0.05). Conclusion Attention should be paid to the influence of ACEs and gender differences during youth development among male and female students, and more longterm studies should also be carried out.

Objective:To evaluate of the general practice residency training bases in Hebei Province.Methods:Based on the 2020 Standardized Residency Training Base Evaluation Index-General Practitioners of Chinese Medical Doctor Association,24 training bases in Hebei Province were assessed;and the satisfaction questionnaire survey and in-depth interview were conducted among 124 general practice trainees who were randomly selected in November 2020. Results:All 24 bases set the general practice department in the hospitals as required. However, the annual outpatient visits in department of general practice were less than 20000 in 45.83% (11/24) bases, only 41.67% (10/24) bases met the teaching requirements of general practice, and 33.33% (8/24) bases fulfilled the provincial target for general practice residency training enrollment; only 3 bases (13.64%) had the pass rate≥85% in medical licensing examination in the previous year. For the training satisfaction, 66.94% (83/124) trainees were satisfied with residency training, and 33.06% (41/124) were moderately satisfied. There was significantly difference in the satisfaction degrees among trainees with different expectations of career prospects (χ 2=24.436, P<0.05). Conclusions:Basically, the management system of general practice residency training bases has been completed and the construction of teaching teams has been standardized in Hebei Province. But the job attraction of general practitioner is inadequate, the training bases need to be strengthened, and the training quality needs to be improved.

Objective:To analyze the current status of faculty development in general practice residency training bases in Hebei Province.Methods:A questionnaire survey with deep interview was conducted among 79 faculty from 24 general practice residency training bases in Hebei Province during November to December 2020.Results:Among 79 participants, 21 were males (26.58%) and 58 were females (73.42%), 41 (51.90%) of whom were aged 31-40 years; 44 (55.70%) were general practitioners, and 35 (44.30%) were specialists. There were no significant differences in sex, age, education background, professional title, between faculty with general practice background and specialist background (all P>0.05); while there were significant differences in job-transfer training, teaching training for general practice, the training form, teaching method grasped, understanding the work contents of general practice, the view and prospect for general practice between general practitioner faculty and specialist faculty (all P<0.05). The score of ward round teaching of general practice faculty was significantly higher than that of specialist faculty ( P<0.05) The interview showed that all faculty members were willing to teach, most of them had increased work pressure after engagement in teaching, and there was lack of incentive policies for teaching in some bases. Conclusions:The current status of faculty development in the general practice residency training base in Hebei Province is basically satisfactory, but there is lack of general practice training for faculty with specialist background; the professional identity of general practitioner need to be enhanced, and their status and treatment need to be improved.

Objective To investigate the influence of WeChat + family centered health intervention on the self-efficacy of elderly hypertensive patients in General clinic. Methods A total of 102 elderly hypertensive patients aged≥60 years in General clinic from February 2017 to July 2017 were enrolled.They were divided into experimental group and control group with the table of random number, with 51 cases in each group. The experimental group used the WeChat+ family centered health intervention model,while the control group adopted the traditional health education model.The changes of blood pressure and self-efficacy were evaluated before intervention, 3 months and 6 months after intervention respectively. Results There were no statistic significant difference in blood pressure and self-efficacy total score between the two groups before intervention(P>0.05). At 3 months after intervention,the blood pressure(systolic pressure/diastolic pressure)of the patients were(144.20±4.60), (80.00±5.00)mmHg(1 mmHg=0.133 kPa)in the experimental group,those of which were(154.20±7.16), (87.00±3.81)mmHg in the control group,the differences were statistically significant (t=-2.628,-2.490,P<0.05).At 6 months after intervention,the blood pressure(systolic pressure/diastolic pressure)of the patients were(141.60±6.43),(76.00±4.85)mmHg in the experimental group,those of which were(151.60± 5.94),(85.40±4.56)mmHg in the control group,the differences were statistically significant (t=-2.555,-3.158,P<0.05).There were differences in systolic and diastolic pressure in patients with different groups at different time,and the differences were statistically significant(F=18.668,18.174,P<0.01).The total score of self-efficacy at 3 months and 6 months after intervention was(30.14±0.43),(32.56±0.23)points in the experimental group and (28.14 ± 0.15), (29.40 ± 0.19) points in the control group, the difference was statistically significant(t=9.736, 23.819, P<0.05). The differences in the total score of patients′self-efficacy in different groups at different time had statistically significance (F=2 631.551, P<0.01). Conclusions The WeChat+family centered health intervention model can significantly improve the self-efficacy of the elderly patients with high blood pressure in the General clinic.
