Objective:To investigate the clinical effect of local injection of triamcinolone acetonide acetate combined with ultra-pulsed CO 2 fractional laser in the treatment of hypertrophic scars in children. Methods:A randomized controlled study method was used. According to the inclusion and exclusion criteria, the subjects were selected from children with hypertrophic scars admitted to the Children’s Hospital Affiliated to Shandong University from January 2022 to September 2023, and were divided into control group and experimental group using random number table method. The control group was treated with ultra-pulsed CO 2 fractional laser. The experimental group was injected with triamcinolone acetonide acetate injection at multiple points into the scar (the ratio of triamcinolone acetonide acetate injection to 2% lidocoin hydrochloride injection was 1∶1), with a distance between the points as 1 cm, and the injection dose was about 0.1 to 0.2 ml/cm 2 according to the degree of scar protrusion. The maximum dose each time was ≤40 mg. CO 2 fractional laser treatment was performed after 10 minutes of cold compress with ice bag. Scars in both groups were treated 3 times, with an interval of 2 to 3 months. Before the treatment and 6 months after the last treatment, the Vancouver scar scale (VSS) was performed on both groups of scars score, the total score was 0 - 15. The higher the score, the more serious the scar hyperplasia was. Six months after the last treatment, the scar treatment effects of the two groups were comprehensively evaluated and divided into 3 levels: markedly effective, effective and ineffective. The total effective rate =(markedly effective + effective) number of cases/total number of cases ×100%. Patient satisfaction was investigated 6 months after the last treatment and divided into 5 levels: very satisfied, satisfied, average, dissatisfied, and very dissatisfied. Satisfaction rate =(very satisfied + satisfied) number of cases/total number of cases ×100%. The occurrence of adverse reactions was recorded throughout the treatment process. Analysis was performed using SPSS 19.0 software. Measurement data were expressed as Mean±SD, inter-group comparisons were performed using independent samples t-test, intra-group comparisons were performed using paired t-test, counting data were expressed as examples and percentages, and comparisons between the two groups were performed using χ2 test. P<0.05 indicated that the difference was statistically significant. Results:A total of 82 children with hypertrophic scars were included, 33 males and 49 females, aged 1 to 15 years old, with an area of 5 to 45 cm 2. The pathogenic factors were trauma, burns, and surgery. The course of disease was 2 to 30 months. Among them, 41 patients in the control group, 16 males and 25 females; the age was (5.8±1.6) years; 41 patients in the experimental group, 17 males and 24 females, the age was (5.6±1.5) years. There were no significant differences in age, gender, scar area, pathogenic factors and course of disease between the two groups ( P>0.05). There was no significant difference in VSS scores between the experimental group and the control group before the treatment [(9.42±1.35) points vs. (9.06±1.57) points, P>0.05]. Six months after the last treatment, there was a significant difference in VSS scores between the experimental group and the control group [(4.12±0.56) points vs. (5.50±0.75) points, P<0.01]. The VSS scores of children in both groups were significantly lower than those before the treatment ( P<0.01). Six months after the last treatment, the comprehensive evaluation result showed that the total effective rate in the experimental group was higher than that in the control group [92.7%(38/41) vs. 75.6%(31/41), P<0.05]. Six months after the last treatment, the patient satisfaction survey showed that the satisfaction rate in the experimental group was higher than that in the control group [87.8%(36/41) vs. 58.5%(24/41), P<0.01]. The main adverse reactions during treatment included edema erythema, skin ruptures, skin atrophy, and vigorous hair growth. There was no significant difference in the incidence of adverse reactions between the experimental group and the control group [12.2%(5/41) vs. 7.3%(3/41), P>0.05]. Conclusion:Local injection of triamcinolone acetonide acetate combined with ultra-pulsed CO 2 fractional laser is more effective in treating children’s hypertrophic scars. It can significantly improve the appearance of scars, reduce clinical symptoms, with fewer adverse reactions, and high patient satisfaction.

Natural products, and especially the active ingredients found in traditional Chinese medicine (TCM), have a thousand-year-long history of clinical use and a strong theoretical basis in TCM. As such, traditional remedies provide shortcuts for the development of original new drugs in China, and increasing numbers of natural products are showing great therapeutic potential in various diseases. This paper reviews the molecular mechanisms of action of natural products from different sources used in the treatment of inflammatory diseases and cancer, introduces the methods and newly emerging technologies used to identify and validate the targets of natural active ingredients, enumerates the expansive list of TCM used to treat inflammatory diseases and cancer, and summarizes the patterns of action of emerging technologies such as single-cell multiomics, network pharmacology, and artificial intelligence in the pharmacological studies of natural products to provide insights for the development of innovative natural product-based drugs. Our hope is that we can make use of advances in target identification and single-cell multiomics to obtain a deeper understanding of actions of mechanisms of natural products that will allow innovation and revitalization of TCM and its swift industrialization and internationalization.

Tyrosine phosphatase SHP2 is a promising drug target in cancer immunotherapy due to its bidirectional role in both tumor growth promotion and T-cell inactivation. Its allosteric inhibitor SHP099 is known to inhibit cancer cell growth both and . However, whether SHP099-mediated SHP2 inhibition retards tumor growth anti-tumor immunity remains elusive. To address this, a CT-26 colon cancer xenograft model was established in mice since this cell line is insensitive to SHP099. Consequently, SHP099 minimally affected CT-26 tumor growth in immuno-deficient nude mice, but significantly decreased the tumor burden in CT-26 tumor-bearing mice with intact immune system. SHP099 augmented anti-tumor immunity, as shown by the elevated proportion of CD8IFN- T cells and the upregulation of cytotoxic T-cell related genes including , which decreased the tumor load. In addition, tumor growth in mice with SHP2-deficient T-cells was markedly slowed down because of enhanced anti-tumor responses. Finally, the combination of SHP099 and anti-PD-1 antibody showed a higher therapeutic efficacy than either monotherapy in controlling tumor growth in two colon cancer xenograft models, indicating that these agents complement each other. Our study suggests that SHP2 inhibitor SHP099 is a promising candidate drug for cancer immunotherapy.

Objective To detect the expression of a novo tumor suppressor gene PTEN and DNA direct repair enzyme MGMT in gynecomastia. Methods Immunohistochemical SP method was used to detect expression of PTEN and MGMT protein in 68 cases of gynecomastia(experiment group) and 24 cases of mammary gland of control group. The selected examples were divided into three different age groups and three different histological types. Results The PTEN and MGMT protein were all expressed in nucleusr of ductal cellula epithelialis. The expression level of PTEN and MGMT proteins in gynecomastia was significantly lower than that of mammary gland of control(P
