Aim To test the skin healing and repairing efficacy and the mechanism of Hibiscus rosa-sinensis L bud extract by using the animal models. Methods KM mice were randomly divided into three groups:the model group, the positive control group, and the n-bu-tyl alcohol extract ( HrBN) group. Using the boils and carbuncles model, the healing condition of all the animals were observed. KM mice were kept in the SPF condition room and divided into five groups: the model group, the positive control group, and the low, middle, high dose groups. Using the full-thickness loss model, the repairing results of all the mice were ob-served. Through the antimicrobial test, the results of MIC and inhibition zone were obtained. The carbon clearance test was used to collect the blood at the time 5min and 15min, and get the liver and spleen, and the results of K andαwere obtained. Results In vivo ex-periments showed there was significant difference be-tween groups;the HrBN extract had the outstanding ef-ficacy in healing and repairing skin boils and full-thickness loss models. It had higher recovery rate than other ethanol extract, such as ethyl acetate extract and chloroform extract. In vitro experiments showed that the HrBN extract, ethyl acetate extract ( HrBE) ,AB-8 macroporous resin 30% alcohol part and 60% alcohol part had obvious antimicrobial efficacy. The carbon clearance test showed HrBN had a good effect in im-proving immune function, and it can increase the K and α. Conclusion HrBN in animal models exerts good skin healing and repairing efficacy, which might be related to its antibacterial activity and immunologic enhancement function.

Objective:To investigate the prognosis of patients with initially resectable gastric cancer liver metastasis (GCLM) who were treated by different modalities, and analyze the influencing factors for prognosis of patients.Methods:The retrospective cohort study was conducted. The clinicopathological data of 327 patients with initially resectable GCLM who were included in the database of a nationwide multicenter retrospective cohort study on GCLM based on real-world data from January 2010 to December 2019 were collected. There were 267 males and 60 females, aged 61(54,68)years. According to the specific situations of patients, treatment modalities included radical surgery combined with systemic treatment, palliative surgery combined with systemic treatment, and systemic treatment alone. Observation indicators: (1) clinical characteristics of patients who were treated by different modalities; (2) prognostic outcomes of patients who were treated by different modalities; (3) analysis of influencing factors for prognosis of patients with initially resectable GCLM; (4) screening of potential beneficiaries in patients who were treated by radical surgery plus systemic treatment and patients who were treated by palliative surgery plus systemic treatment. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the rank sum test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. The Kaplan-Meier method was used to calculate survival rate and draw survival curve, and Log-Rank test was used for survival analysis. Univariate and multivariate analyses were conducted using the COX proportional hazard regression model. The propensity score matching was employed by the 1:1 nearest neighbor matching method with a caliper value of 0.1. The forest plots were utilized to evaluate potential benefits of diverse surgical combined with systemic treatments within the population. Results:(1) Clinical characteristics of patients who were treated by different modalities. Of 327 patients, there were 118 cases undergoing radical surgery plus systemic treatment, 164 cases undergoing palliative surgery plus systemic treatment, and 45 cases undergoing systemic treatment alone. There were significant differences in smoking, drinking, site of primary gastric tumor, diameter of primary gastric tumor, site of liver metastasis, and metastatic interval among the three groups of patients ( P<0.05). (2) Prognostic outcomes of patients who were treated by different modalities. The median overall survival time of the 327 pati-ents was 19.9 months (95% confidence interval as 14.9-24.9 months), with 1-, 3-year overall survival rate of 61.3%, 32.7%, respectively. The 1-year overall survival rates of patients undergoing radical surgery plus systemic treatment, palliative surgery plus systemic treatment and systemic treatment alone were 68.3%, 63.1%, 30.6%, and the 3-year overall survival rates were 41.1%, 29.9%, 11.9%, showing a significant difference in overall survival rate among the three groups of patients ( χ2=19.46, P<0.05). Results of further analysis showed that there was a significant difference in overall survival rate between patients undergoing radical surgery plus systemic treatment and patients undergoing systemic treatment alone ( hazard ratio=0.40, 95% confidence interval as 0.26-0.61, P<0.05), between patients undergoing palliative surgery plus systemic treatment and patients under-going systemic treatment alone ( hazard ratio=0.47, 95% confidence interval as 0.32-0.71, P<0.05). (3) Analysis of influencing factors for prognosis of patients with initially resectable GCLM. Results of multivariate analysis showed that the larger primary gastric tumor, poorly differentiated tumor, larger liver metastasis, multiple hepatic metastases were independent risk factors for prognosis of patients with initially resectable GCLM ( hazard ratio=1.20, 1.70, 1.20, 2.06, 95% confidence interval as 1.14-1.27, 1.25-2.31, 1.04-1.42, 1.45-2.92, P<0.05) and immunotherapy or targeted therapy, the treatment modality of radical or palliative surgery plus systemic therapy were independent protective factors for prognosis of patients with initially resectable GCLM ( hazard ratio=0.60, 0.39, 0.46, 95% confidence interval as 0.42-0.87, 0.25-0.60, 0.30-0.70, P<0.05). (4) Screening of potentinal beneficiaries in patients who were treated by radical surgery plus systemic treatment and patients who were treated by palliative surgery plus systemic treatment. Results of forest plots analysis showed that for patients with high-moderate differentiated GCLM and patients with liver metastasis located in the left liver, the overall survival rate of patients undergoing radical surgery plus systemic treatment was better than patients undergoing palliative surgery plus systemic treatment ( hazard ratio=0.21, 0.42, 95% confidence interval as 0.09-0.48, 0.23-0.78, P<0.05). Conclusions:Compared to systemic therapy alone, both radical and palliative surgery plus systemic therapy can improve the pro-gnosis of patients with initially resectable GCLM. The larger primary gastric tumor, poorly differen-tiated tumor, larger liver metastasis, multiple hepatic metastases are independent risk factors for prognosis of patients with initial resectable GCLM and immunotherapy or targeted therapy, the treatment modality of radical or palliative surgery plus systemic therapy are independent protective factors for prognosis of patients with initially resectable GCLM.

Objective:To investigate the clinical features and multimodal imaging features of eyes with perifoveal exudative vascular anomalous complex (PEVAC).Methods:A retrospective case study. From February 2014 to November 2020, 7 eyes of 7 patients with PEVAC diagnosed by ophthalmology examination in Department of Ophthalmologyof Peking University People's Hospital were included in this study. There were 6 males and 1 female. The age was 60.1±9.1 years. All were monocular. The chief complaints of visual deformation and vision loss were 3 and 1 cases, respectively. All patients underwent best corrected visual acuity (BCVA), fundus color photography, optical coherence tomography (OCT), fundus fluorescein angiography (FFA). BCVA examination was performed using the standard logarithmic visual acuity chart, which was converted to logarithm of the minimum angle of resolution (logMAR) visual acuity. OCT angiography (OCTA) and indocyanine green angiography (ICGA) were performed in 4 and 2 eyes, respectively. Three eyes were treated with intravitreal injection of anti-vascular endothelial growth factor (VEGF) combined with local laser photocoagulation. Two eyes were treated with laser photocoagulation alone. The follow-up time was 16.7±19.1 months. During follow-up, relevant examinations were performed with the same equipment and methods as at the initial diagnosis. The multimodal imaging characteristics and treatment response of the affected eyes were observed.Results:The baseline logMAR BCVA was 0.33±0.19 (0.20-0.80). All eyes showed isolated hemangiomatous lesions in the macular fovea with rigid retinal exudation, and 2 adjacent isolated hemangiomatous lesions were observed in 1 eye. FFA and ICGA examination showed that all eyes with macular hemangiomatous lesions showed clear boundary and strong fluorescence in the early stage. No other retinal or choroidal vascular abnormalities were observed. On OCT examination, circular lumen-like structures with strong reflective wall near the fovea were observed in the macular region of all eyes, accompanied by intraretinal cystic lumen. The macular central retinal thickness (CMT) was 326±125 (207-479) μm. In the four eyes examined by OCTA, blood flow signals were observed in the circular lumenoid structures with strong reflective walls adjacent to the fovea. Blood flow signals were observed in the superficial capillary layer (SCP) and deep capillary layer (DCP) of the retina in 3 eyes. SCP showed blood flow signal in 1 eye. In 4 eyes treated with intravitreal injection of anti-VEGF drugs, there was no significant improvement in the intraretinal capsule space after treatment. Subretinal fluid absorption, retinal cystoid edema persisted, and rigid exudation decreased in 1 eye. CMT decreased and BCVA increased in 5 eyes treated with laser photocoagulation or laser photocoagulation alone. At last follow-up, logMAR BCVA was 0.16±0.06 (0.10-0.20) and CMT was 212±34 (154-252) μm. Compared with baseline, the difference of BCVA was statistically significant ( t=2.661, P=0.037). Conclusions:The fundus of PEVAC patients is characterized by solitary or multiple solitary hemangiomatous lesions in the macular fovea. Round lumenoid structures with strong reflective walls, with or without intraretinal cystic lumen, rigid exudate, and subretinal fluid, in which blood flow signals can be seen in OCT.
