Objective:To explore the effect of prognosis appearance of the combination of microneedle array radiofrequency and CO2 array laser on psychological stress response of patients with facial acne scar.Methods:A total of 100 patients with facial acne scar,who admitted to Chengdu Second People's Hospital from August 2020 to August 2020,were selected,and they were divided into study group and control group,with 50 cases in each group.Study group adopted combined treatment with microneedle array radiofrequency and CO2 array laser,and control group adopted microneedle array radiofrequency to conduct treatment.The curative effect after treatment was compared between two groups.The Vancouver scar scale(VSS)was adopted to score the scar condition of patients,and Hamilton anxiety(HAMA)rating scale,Hamilton depression(HAMD)of rating scale and self-esteem scale(SES)were adopted to evaluate the psychological stress response of patients,and the score of the comprehensive evaluation questionnaire of quality of life(GQOLI-74 score)was adopted to evaluate the difference of quality of life of patients between before and after treatment.Results:After treatment,the overall curative effect of study group was 92.00%,which was better than 72.00%of control group,and the difference was significant(x2=6.775,P<0.05).The VSS scores of study group after received treatment of 2,4 times were significantly lower than those before treatment,and were lower than those of control group,and the differences of those between two groups were significant(t=5.850,9.040,P<0.05),respectively.After treatment,the SES scores of two groups all rose,and the HAMD and HAMA scores of two groups all reduced,and the three scores of study group were all better than those of control group,and the differences of them between two groups were significant(t=3.456,3.909,6.063,P<0.05).Pearson correlation showed that the VSS score was negatively correlated with the SES score(r=-0.249,P<0.05),and was positively correlated with the HAMD score and the HAMA score(r=0.653,0.695,P<0.05),respectively.After treatment,the GQOLI-74 scores of each indicator(material and life,physical function,psychological function,and social function)of two groups rose all,and the GQOLI-74 scores of study group were all better than those of control group,and the differences of them between two groups were significant(t=4.324,7.497,3.870,4.534,P<0.05),respectively.Conclusion:The combination of microneedle array radiofrequency and CO2 array laser has better curative effect in treating facial acne scar,which can effectively promote prognosis appearance,and relieve psychological stress response,and improve the quality of life.

ObjectiveTo investigate the clinical efficacy and safety of state-target formula Angelica and Safflower spot removal essence in the treatment of melasma. MethodsA randomized，double-blind，placebo-controlled parallel-group trial was conducted，selecting patients with Qi stagnation and blood stasis type of melasma who visited the dermatology outpatient department of Beijing Hospital of Integrated Traditional Chinese and Western Medicine from September 2022 to February 2023. In accordance with the double-blind principle，a random number table was generated to randomly divide the patients into an experimental group （50 cases） and a control group （50 cases）. The experimental group applied the Angelica and Safflower spot removal essence topically，while the control group applied a placebo topically，with continuous treatment for 8 weeks and a follow-up of 1 month. Melasma Area and Severity Index （MASI），Physician Global Assessment （PGA），patient self-assessment scoring，VISIA detection and scoring were performed before medication and on the first day after stopping medication，and all adverse events were recorded. ResultsIn a study involving 100 patients，87 cases were included in the analysis. The experimental group consisted of 45 cases，with 5 dropouts，and the control group had 42 cases，with 8 dropouts. The baseline data of the patients in both groups were consistent，with no statistically significant differences. After treatment，the total effective rate of the experimental group was 75.56% （34/45），significantly higher than the control group's 2.38% （1/42），and the difference was statistically significant （χ²=48.38，P<0.01）. Compared with before treatment，after treatment，the MASI score，VISIA image spot，brown spot，and red area score of the experimental group patients were significantly reduced （P<0.05，P<0.01），while there was no statistically significant difference in the control group patients. Compared with the control group after treatment，the experimental group showed more significant improvement （P<0.05，P<0.01）. VISIA image analysis showed that after 8 weeks of treatment，the experimental group showed significant improvement in surface spots，deep spots，and red areas，while the control group remained unchanged or showed an increasing trend. 42.22% （19/45） of the experimental group had a PGA score of 3 or below，while 88.89% （40/45） had a PGA score of 4 or below. 80.95% （34/42） of the control group had a PGA score of 5 or above，and the difference between the two groups was statistically significant （χ²=38.26，P<0.01）. There was no statistically significant difference in the recurrence rate and adverse reaction rate within one month between the experimental group and the control group. ConclusionThe state-target formula Angelica and Safflower spot removal essence is clinically effective and safe in the treatment of melasma.

Objective:To evaluate the impact of postoperative radiotherapy (RT) and associated risk factors on the prognosis of patients undergoing postmastectomy breast reconstruction (PMBR) for breast cancer.Methods:A retrospective analysis was conducted on 1593 breast cancer patients who underwent PMBR at Tianjin Medical University Cancer Institute & Hospital between January 2010 and October 2023. Patients were divided into an RT group ( n = 351) and a non-RT group ( n =1242) based on whether postoperative radiotherapy was administered. The primary endpoints were overall survival (OS) and progression-free survival (PFS), and the secondary endpoint was the incidence of revision surgery. Propensity score matching (PSM) and inverse probability of treatment weighting (IPTW) were used for pairing. Continuous variables were compared between the two groups using the independent samples t-tests, while categorical variables were compared using chi-square tests, and survival analysis was performed using the Kaplan-Meier method. Cox proportional hazards model was used to analyze survival influencing factors, and include propensity factors with P<0.2 in univariate analysis into multivariate analysis. Results:In the RT group, there were 3 deaths (0.9%) and 21 cases of disease progression (6.0%); in the non-RT group, 7 patients died (0.56%) and 40 experienced disease progression (3.22%). The median OS was 20.1 months (range: 0.1-164.9), and the median PFS was 19.5 months (range: 0.1-160.9). Pregnancy-associated breast cancer and higher N stage were identified as significant risk factors for OS, while neoadjuvant therapy, absence of adjuvant chemotherapy or endocrine therapy, and higher T stage were significant risk factors affecting patients' PFS. Radiotherapy significantly reduced the survival risk for PMBR patients with pregnancy-associated breast cancer or those receiving neoadjuvant therapy ( P=0.019, 0.027). Compared with other reconstruction methods, implant-based reconstruction was associated with a lower incidence of postmastectomy revision surgery(10.5% vs. 17.0%, P<0.001). Even after radiotherapy, the revision surgery incidence for implant-based reconstruction remained lower than that of other methods (12.2% vs. 14.2%, P=0.591). Compared with other reconstruction types, expander-based reconstruction was associated with an increased incidence of revision surgery (31.9% vs. 10.9%, P<0.001). Conclusions:Postmastectomy radiotherapy can reduce survival risk in PMBR patients with pregnancy-associated breast cancer or who received neoadjuvant therapy, showing positive effects on OS and PFS in high-risk patients. Pregnancy, higher T/N stage, and specific treatment strategies are critical factors influencing the prognosis of PMBR patients. Implant-based reconstruction is associated with a lower incidence of revision surgery, which remains low even after RT, whereas expander-based reconstruction may increase the long-term risk of revision surgery.

Background::Breast cancer is ranked among the most prevalent malignancies in the Chinese female population. However, comprehensive reports detailing the latest epidemiological data and attributable disease burden have not been extensively documented.Methods::In 2018, high-quality cancer surveillance data were recorded in 700 population-based cancer registries in China. We extracted data on female breast cancers (International Classification of Diseases, Tenth Revision [ICD-10]: C50) and estimated the incidence and mortality in 2022 according to the baseline data and corresponding trends from 2010 to 2018. Pathological types were classified according to the ICD for Oncology, 3rd Edition codes. Disability-adjusted life years (DALYs) were calculated as the sum of the years of life lost (YLLs) and years lived with disability (YLDs).Results::In 2022, approximately 357,200 new female breast cancer cases and 75,000 deaths occurred in China, accounting for 15.59% and 7.94% of total new cancer cases and deaths, respectively. The age-standardized incidence rate (ASIR) was 33.04 per 100,000. When analyzed by pathological type, the ASIRs for papillary neoplasms, invasive breast carcinoma, rare and salivary gland-type tumors, and other types were 1.13, 29.79, 0.24, and 1.88 per 100,000, respectively. The age-standardized mortality rate (ASMR) was 6.10 per 100,000. A total of 2,628,000 DALYs were found to be attributable to female breast cancer in China, comprising 2,278,300 YLLs and 349,700 YLDs. The ASIR, ASMR, and age-standardized rate (ASR) for DALYs in urban areas were consistently higher than those in rural areas. We observed a four-fold increase in the ASIR and ASR for DALYs and an eight-fold increase in the ASMR among females over 55 years compared with those aged under 55 years.Conclusion::These data provide invaluable insights into the latest epidemiology of female breast cancer in China and highlight the urgency for disease prevention and control strategy formulation.

Objective:To explore the interleukin-31 protein expression in the hypertrophic scar of incision tissue after surgery and its underlying pathological impact.Methods:From February 2022 to February 2023, three HS patients scar tissue (HS) and their normal skin tissue (Control, NS) were obtained. Two patients were female and one patient was male. The tissues were fixed in 4% formalin and embedded in paraffin. Haematoxylin-eosin (HE) stain and immunohistochemical stain were used to evaluate the epidermal thickness, myofibroblasts of dermis and the expression level of IL-31 between HS and NS.Results:The epidermis thickness was (303.88±46.03) μm in HS group, while (133.02±17.40) μm in NS group ( t=12.60, P<0.001). The expression level of IL-31 protein was measured by IRS score and positive cell density. The IRS score was 9.89±2.03 of the basal layer in HS group and was 4.33±1.66 of the basal layer in NS group. The positive cell density was 786 343.83±159 627.97 of the basal layer in HS group ( P<0.001) and was 555 457.61±128 097.21 of the basal layer in NS group ( P=0.014). In the dermis layer, the IRS score was 7.11±1.05 in HS group and was 4.33±0.71 in NS group, the positive cell density was 156 760.97±26 046.10 in HS group ( P<0.001) and was 49 576.01±52 369.33 in NS group ( P<0.001). In the dermis layer, the count of myofibroblasts was 120.44±15.75 in HS group while was 27.39±14.89 in NS group ( t=23.79, P<0.001). Conclusions:Our study demonstrates that both myofibroblast count and IL-31 protein expression level are notably increased in HS patients. The expression of IL-31 protein is prominent in the cytoplasm of myofibroblasts, basal cells, macrophages and mast cells which could implicate that IL-31 may be a potential therapeutic target to enhance the resolution of HS.
