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.

OBJECTIVE: To observe the clinical efficacy of different treatment frequency of auricular bloodletting combined with auricular point sticking for acne vulgaris. METHODS: A total of 90 patients with acne vulgaris were randomized into a treatment group 1 (30 cases, 2 cases dropped off), a treatment group 2 (30 cases, 4 cases dropped off) and a treatment group 3 (30 cases, 5 cases dropped off). Combination therapy of auricular bloodletting and auricular point sticking at Fei (CO₁₄), Shenmen (TF₄), Neifenmi (CO₁₈) and Shenshangxian (TG₂p) were given once a week, twice a week and 3 times a week in the treatment group 1, the treatment group 2 and the treatment group 3 respectively, 4 weeks were as one course and totally 3 courses were required in the 3 groups. Before treatment and after 1, 2, 3 courses of treatment, the scores of global acne grading system (GAGS), skin lesion and quality of life-acne (QoL-Acne) were observed, the clinical efficacy was evaluated after 3 courses of treatment and the recurrence rate was evaluated in follow-up of 1 month after treatment in the 3 groups. RESULTS: Compared before treatment, the scores of GAGS and skin lesion were decreased at each time point in the 3 groups (P<0.05), the QoL-Acne scores were increased after 1 course of treatment in the treatment group 3 and after 2, 3 courses of treatment in the 3 groups (P<0.05). There were no statistical differences in scores of GAGS, skin lesion and QoL-Acne among the 3 groups (P>0.05). There were no statistical differences in effective rate and recurrence rate among the 3 groups (P>0.05). CONCLUSION Different frequency of auricular bloodletting combined with auricular point sticking have similar efficacy in treating acne vulgaris, all can improve the skin lesion and quality of life in patients with acne vulgaris, and have a cumulative effect and good long-term curative effect.

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.

Objective To study the influence of recombinant bovine basic fibroblast growth factor as an adjuvant therapy on scar alleviation and inflammatory cytokines in patients with atrophic acne scar. Methods The random number table was employed to randomly assign 120 patients with atrophic acne scar into a test group and a control group.Both groups of patients were treated with CO₂ lattice laser.After the operation,the control group was routinely smeared with erythromycin ointment and the test group was coated with recombinant bovine basic fibroblast growth factor gel.The clinical efficacy,clinical indicators,scar alleviation,and inflammatory cytokine levels before and after treatment were compared,and adverse reactions were counted. Results The test group had higher total effective rate(P=0.040) and lower total incidence of adverse reactions(P=0.028) than the control group.Compared with the control group,the test group showcased short erythema duration after treatment(P=0.025),early scab forming(P=0.002),and early edema regression(P<0.001).After treatment,the proportion of grade 1 scars graded by Goodman and Baron's acne scar grading system in the test group and control group increased(P=0.001,P=0.027),and the proportion of grade 4 scars decreased(P<0.001,P=0.034).Moreover,the proportion of grade 1 scars in the test group was higher than that in the control group(P=0.031) after treatment,and the proportion of grade 4 scars presented an opposite trend(P=0.031).After treatment,the levels of tumor necrosis factor-α(TNF-α) and interleukin-1β(IL-1β) in both groups declined(all P<0.001),and the test group had lower TNF-α and IL-1β levels than the control group(all P<0.001). Conclusion The recombinant bovine basic fibroblast growth factor gel as an adjuvant therapy of CO₂ lattice laser can effectively alleviate the atrophic acne scar,relieve local inflammatory reaction,and has good curative effect and less adverse reactions.

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.

Background: Acne vulgaris is a chronic inflammatory condition of the pilosebaceous unit. Isotretinoin is used to treat moderate to severe acne that is resistant to antibiotics and topical agents. However, it may cause alterations in lipids and liver enzymes. Methods: A total of 129 patients with acne vulgaris (moderate to severe facial acne) treated with isotretinoin were recruited between May 2020 and July 2021 from the dermatology clinics at Hospital Serdang and Hospital Kuala Lumpur. Of these, 120 patients with complete data of lipid panel (total cholesterol, low density lipoprotein cholesterol [LDL], triglycerides [TG], and high density lipoprotein cholesterol [HDL]) and hepatic panel (alanine transaminase [ALT] and aspartate transaminase [AST]) levels at baseline, and in three subsequent follow-up visits (i.e., one, three, and six months) were included in the analyses. Abnormalities were graded according to standard laboratory values and their severity according to the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE)grading system. Results: Of the 120 study participants, 83% were female and 37% were male between the ages of 15 and 36 years. We observed a significant increase in median values at baseline and at the six-month follow-up for total cholesterol (p<0.0001), triglycerides (p<0.0001), LDL (p<0.0001), ALT (p<0.0001), and AST (p<0.0001). We observed a significant correlation between body mass index and the HDL (r2 =- 0.26, p=0.01) and ALT (r2 =0.383, p=7.9x10-06) levels. Based on the CTCAE grading system, almost all study participants with abnormal results had grade 1 abnormalities. Only one patient had a grade 2 abnormality in ALT, which required treatment discontinuation. Conclusion Low dose isotretinoin therapy for acne vulgaris may cause mild and non-progressive elevation of LDL, total cholesterol, and liver transaminases which do not require treatment withdrawal in most cases.

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.

Background: Acne vulgaris is a common chronic inflammatory skin disease. Long term therapy involving antibiotics warrants for drug with a long half-life to increase compliance of patients. Methods: A twelve-week prospective randomized study was performed on 40 subjects with moderate to severe facial acne to compare the efficacy of oral azithromycin with oral doxycycline. Thirty-six subjects completed the study. Subjects in azithromycin group received azithromycin 250mg three times a week plus topical benzoyl peroxide 5% (BPO), whereas subjects in doxycycline group received doxycycline 100mg daily plus topical BPO 5%. Efficacy evaluation included treatment success rate (Comprehensive Acne Severity Score /CASS of 0 or 1 or improvement of two grades from baseline) and lesion counts. Results: Treatment was successful in 94.4% of subjects in azithromycin group, compared to 88.9% in doxycycline group (p=1.000) at week 12.However, percentage of clear or almost clear by CASS was higher in the doxycycline group ( 83.3% vs 66.7%; p= 0.443).Percentage reduction of inflammatory lesion counts in azithromycin and doxycycline group following treatment for 12 weeks were 78.3% and 85.3% (p=0.133) respectively, whereas for non-inflammatory lesion counts were 77.7% and 78.8% (p=0.852) respectively. Nausea was reported in 77.8% at week 6 and 66.7% at week 12 in doxycycline group, but none in azithromycin group. There were no significant differences in incidence of diarrhoea and abdominal pain. Conclusion Azithromycin 250mg three times a week plus topical BPO 5% is as effective as doxycycline 100mg daily plus topical BPO 5%.
