Clinical effects of fractional carbon dioxide laser combined with minimally invasive scar release in the treatment of post-acne atrophic scars / 中华烧伤杂志

Objective: To explore the clinical effects of fractional carbon dioxide laser combined with minimally invasive scar release in the treatment of post-acne atrophic scars. Methods: A retrospectively observational study was conducted. From January to June 2021, 60 patients with grade 3 and 4 post-acne atrophic scars who met the inclusion criteria were admitted to the First Affiliated Hospital of Henan University of Traditional Chinese Medicine. According to the adopted treatment methods, 30 patients treated with fractional carbon dioxide laser combined with minimally invasive scar release were included in combined treatment group (19 males and 11 females, aged (26±4) years), and 30 patients treated with fractional carbon dioxide laser alone were included in laser alone group (18 males and 12 females, aged (25±6) years). All the patients received the treatment once every two months, totally 3 times. Before the first treatment and 2 months after the last treatment, the scars were assessed by échelle d'évaluation clinique des cicatrices d'acné (ECCA). In 2 months after the last treatment, the curative effect was evaluated and the total effective rate was calculated according to the ECCA score. The adverse reactions of patients during the treatment were recorded. Data were statistically analyzed with independent sample t test, Wilcoxon rank-sum test, Mann-Whitney U test, chi-square test, and Fisher's exact probability test. Results: Before the first treatment, the ECCA scores of patients in the two groups were similar (P>0.05). In 2 months after the last treatment, the ECCA scores of patients in combined treatment group were significantly lower than those of laser alone group (Z=-2.89, P<0.05). The ECCA scores of patients in combined treatment group and laser alone group in 2 months after the last treatment were both significantly lower than those before the first treatment (with Z values of -4.81 and -4.79, respectively, P<0.05). In 2 months after the last treatment, the treatment in laser alone group cured the scars in 2 patients, and were markedly effective in 13 patients, effective in 7 patients, and ineffective in 8 patients; the treatment in combined treatment group cured the scars in 4 patients, and were markedly effective in 22 patients, effective in 3 patients, and ineffective in one patients. The total effective rate of scar treatment in combined treatment group (96.67%, 29/30) was significantly higher than 73.33% (22/30) in laser alone group (P<0.05). During treatment, in combined treatment group, 3 patients had pain, one patient had redness and swelling, and one patient had pigmentation. In laser alone group, one patient had pain, and 2 patients had pigmentation. No infection occurred in the wounds of all the patients in the two groups. Conclusions: Compared with fractional carbon dioxide laser alone, fractional carbon dioxide laser combined with minimally invasive scar release for post-acne atrophic scars can result in a higher total effective rate, with simple operation and good effect, so it is worthy of clinical application.

Body dysmorphia and selfie behavior of Filipino patients with and without mild acne vulgaris: A descriptive cross-sectional study

Background@#Acne vulgaris (AV) is a chronic inflammatory skin condition that is non-life-threatening but may cause significant psychological morbidity regardless of severity. An extreme case of this is depicted in body dysmorphic disorder (BDD), which is often an undiagnosed condition presenting with excessive preoccupation of perceived flaws not observable by others. With the increasing popularity of social media throughout the years, there has been budding researches exploring its psychological implications, particularly on “selfies” and its possible association with self-image and body dysmorphia.@*Objectives@#To compare body dysmorphic symptoms and selfie behavior between patients with mild AV versus those without AV. Methods This is a single-center, cross-sectional study among patients with mild AV and those without AV seen through a teledermatology platform of a tertiary hospital from April to June 2022. @*Results@#A total of 207 patients were included in this study – 107 patients with mild AV and 100 patients without AV. A significantly higher proportion of BDD symptoms was seen in patients with mild AV using either Body Dysmorphic Disorder Questionnaire-Dermatology Version (BDDQ-DV) (31%) and Dysmorphic Concern Questionnaire (DCQ) (14%). No significant difference was noted in terms of selfie behavior between the groups. @*Conclusions@#BDD symptoms were significantly more prevalent in patients who have mild AV despite having lesions that are negligible and clinically not apparent. This highlights the importance of dermatologists’ knowledge that BDD may cause distress and impairment and should be taken into consideration in terms of management. Interestingly, selfie behavior of patients with mild AV and without AV had no significant difference.

Research advances on mesenchymal stem cells and their derivatives in the treatment of acne scars / 中华烧伤杂志

Acne is a common chronic inflammatory disease of the skin that often occurs on the face, and acne scars are often secondary to the healing process of acne, which often leads to impaired appearance and psychological disorders of patients. The current treatment for acne scars is extremely difficult. With the development of regenerative medicine, stem cell transplantation has become a new treatment for acne scars. In recent years, it has been reported that stem cells and their derivatives can effectively antagonize the formation of acne scars. Therefore, this paper briefly reviews the basic and clinical researches on the treatment of acne scars with various mesenchymal stem cells and their derivatives, aiming to provide theoretical basis and reference for the stem cell therapy of acne scars.

OBJECTIVE@#To evaluate the efficacy and safety of 585 nm Q-switched laser in the treatment of acne inflammatory lesions and postinflammatory erythema.@*METHODS@#A total of 25 patients with moderate facial acne, symmetrical distribution of inflammatory lesions and postinflammatory erythema on both sides of the face, were enrolled. Among the 25 patients, 22 patients completed all the treatment and evaluation, and 3 patients were lost to follow-up. 585 nm Q-switched laser was used on a randomly selected side of the face for three times of treatment at a 2 week interval. The evaluations were made before each treatment, 2 and 4 weeks after the last treatment, therefore the evaluation time points were before the treatment, weeks 2, 4, 6, and 8, respectively, for a total of 5 times. Acne severity was assessed using the investigator' s global assessment (IGA) score, and erythema severity was assessed using the investigator' s subjective erythema score and narrow-spectrum reflectance spectrophotometer at each follow-up.@*RESULTS@#After 3 times of treatment, there was statistically significant difference between the IGA score in week 8 and before treatment on both sides(Z=2.64, P < 0.01; Z=2.67, P < 0.01). There was no significant difference in IGA score between the treatment side and the control side before treatment and in week 8 (P=0.59, P=0.26). There was statistically significant difference between the investiga-tor' s subjective erythema score in week 8 and before treatment on the treatment side(Z=4.24, P < 0.01), while no significant difference was showed on the control side(Z=1.73, P=0.08). In week 8, the investigator's subjective erythema score of the treatment side was lower than that of the control side (Z=3.61, P < 0.01). The erythema index of the treatment side was significantly decreased at 5 time points (P < 0.01), and the index decreased significantly in week 8 compared with the index before treatment (P < 0.01), while the erythema index of the control side was not significantly different at 5 time points. The treatment related adverse events included erythema and edema after treatment and pain during treatment, the severity was mild to moderate, which resolved spontaneously within 1 to 3 days. Nine patients were very satisfied with the treatment, 7 patients were satisfied, and 6 patients considered average.@*CONCLUSION@#585 nm Q-switched laser has some effect in the treatment of postinflammatory erythema, and it ensures good tolerance and safety. There was no statistically significant difference between the treatment side and the control side on the improvement of acne inflammatory lesions.

Preparation of tanshinone Ⅱ_A-glycyrrhetinic acid solid lipid nanoparticles and its inhibitory effect on acne / 中国中药杂志

The optimal prescription of tanshinone Ⅱ_A(TSN)-glycyrrhetinic acid(GA) solid lipid nanoparticles(GT-SLNs) was explored and evaluated in vivo and in vitro, and its effect on acne after oral administration was investigated. The preparation processing and prescription were optimized and verified by single factor and response surface methodology. The in vitro release of GA and TSN in GT-SLNs was determined by ultra-performance liquid chromatography(UPLC). The effect of GT-SLNs on acne was investigated by the levels of sex hormones in mice, ear swelling model, and tissue changes in sebaceous glands, and the pharmacokinetics was evaluated. The 24-hour cumulative release rates of GA and TSN in SLNs were 65.87%±5.63% and 36.13%±2.31% respectively. After oral administration of GT-SLNs and the mixture of GA and TSN(GT-Mix), the AUC_(0-t) and AUC_(0-∞) of TSN in GT-SLNs were 1.98 times and 4.77 times those in the GT-Mix group, respectively, and the peak concentration of TSN in the GT-SLNs group was 17.2 times that in the GT-Mix group. After intragastric administration of GT-SLNs, the serum levels of testosterone(T) and the ratio of testosterone to estradiol(T/E2) in the GT-SLNs group significantly declined, and the sebaceous glands of mice were atrophied to a certain extent. The results demonstrated that obtained GT-SLNs with good encapsulation efficiency and uniform particle size could promote the release of GA and TSN. GT-SLNs displayed therapeutic efficacy on acne manifested by androgen increase, abnormal sebaceous gland secretion, and inflammatory damage.

Analysis on formulation regularity and characteristics of acne-relieving Chinese medicinal health products and Chinese patent medicines / 中国中药杂志

This study summarized and analyzed the current acne-relieving Chinese medicinal health products and Chinese patent medicines,aiming at providing references for the formulation and development of acne-relieving health products. The information on acne-relieving health products published by the Department of Special Food Safety Supervision and Management,the State Administration for Market Regulation( SAMR) was retrieved,and the Chinese patent medicines on DRUGDATAEXPY were searched. Microsoft Excel and the Traditional Chinese Medicine Inheritance Support System V2. 5( TCMISS) were employed to statistically analyze the characteristics of formulations. Forty-three acne-relieving health products were obtained,including 40 ones containing Chinese herbal medicines. Six Chinese herbal medicines showed a usage frequency ≥8,with 61 times in use totally,including Salviae Miltiorrhizae Radix et Rhizoma( 13),Lonicerae Japonicae Flos( 12),Taraxaci Herba( 11),ALOE( 9),Carthami Flos( 8),and Rhei Radix et Rhizoma( 8). A total of 29 Chinese patent medicines with similar efficacy were collected in DRUGDATAEXPY. Nine Chinese herbal medicines showed a usage frequency ≥6,with 63 times in use,including Rhei Radix et Rhizoma( 10),Glycyrrhizae Radix et Rhizoma( 8),Scutellariae Radix( 8),Lonicerae Japonicae Flos( 7),Angelicae Sinensis Radix( 6),Paeoniae Radix Rubra( 6),Astragali Radix( 6),Paeoniae Radix Alba( 6),and Gardeniae Fructus( 6). Through unsupervised hierarchical entropy-based clustering of the above-mentioned Chinese medicinal health products and Chinese patent medicines,five and three new formulas were obtained,respectively. The selection of Chinese herbal medicines was consistent with the principles of traditional Chinese medicine( TCM) theories in relieving acne,i. e.,dispelling exterior wind,ventilating lungs,clearing heat,dissipating mass,promoting diuresis,relaxing bowels,removing toxin,activating blood,resolving stasis,eliminating phlegm,and regulating Qi. According to the " lung governing skin and body hair" and " interior-exterior relationship between lung and large intestine" in TCM theories,the idea that acne could be treated by relieving constipation was proposed,which provided new methods and references for the research and development of Chinese medicinal health products.
