Objective:To explore the clinical effect on the treatment of radiation induced deep ulcers in the inguinal region with ipsilateral anterolateral thigh chimeric perforator flap.Methods:From March 2020 to March 2024, retrospective analysis of 8 patients with radiation induced deep ulcers in the inguinal region were treated with ipsilateral anterolateral thigh chimeric perforator flap in the Medical Centre of Burn Plastic and Wound Repair, the First Affiliated Hospital of Nanchang University. All ulcers induced by radiation were caused by postoperative radiotherapy in the inguinal region, of which 4 were of vulvar or penile cancer, 2 of urinary tract tumour, 1 of inguinal protuberant dermatofibrosarcoma and 1 of myofibroblastic sarcoma in lower abdominal wall. The course of the radiation induced ulcer was 0.5-11.0 years, with an average of 2.9 years. The sizes of the ulcerative wound were 2.5 cm × 3.0 cm - 5.5 cm × 7.5 cm. Preoperative biopsies of the tissues around wound and pelvic CT scans were performed to preliminarily exclude a tumour recurrence or an ulcerative malignancy, as well as to confirm the depth of radiation ulcer. The wound size after debridement was 4.5 cm × 6.0 cm-13.5 cm × 19.0 cm, with a depth of 2.0-4.0 cm. An ipsilateral anterolateral thigh chimeric perforator flap was transferred to reconstruct the wound, after the wound edges were cleared from tumour through intraoperative frozen section examinations. The flaps were 5.5 cm × 7.0 cm - 14.0 cm × 20.0 cm in size, with the volumes of muscle flap at 7.0 cm × 4.0 cm × 3.0 cm - 14.0 cm × 7.0 cm × 3.0 cm. After having the deep defect at the base of wound filled with a muscle flap, the wound surface was covered by the flap. Four patients had direct suture of the donor sites and 4 received a thick skin graft of head or contralateral thigh grafting. Survival of the anterolateral thigh chimeric perforator flaps and the healing of donor sites were observed after surgery through scheduled postoperative follow-up by the visits of outpatient clinic and distant interviews via telephone, WeChat or the internet hospital.Results:One of the ipsilateral anterolateral thigh chimeric perforator flaps had venous occlusion within 24 hours after surgery. Emergency surgical exploration revealed that it was caused by a haematoma compression due to haemorrhage in the muscle flap. Further debridement, haemostasis and suture were performed, then the wound healed. The rest of 7 flaps all survived. All donor sites healed primarily. The postoperative follow-up lasted for 5-17 months with all of the 8 patients, at 8.4 months in average. Both the donor and recipient sites healed well without recurrence of radiation ulcer in the affected sites. The appearance and texture of the flaps were good, and there was no obvious functional impairment at the donor sites.Conclusion:The treatment of radiation induced deep ulcer in the inguinal region with an ipsilateral anterolateral thigh chimeric perforator flap has shown good results, without recurrence of ulcer after surgery. The appearance and texture of the affected sites are good, and there is no secondary functional impairment at the donor site.

Objective To explore the differences in clinical characteristics of sudden sensorineural hearing loss(SSNHL)between patients with coronavirus disease 2019(COVID-19)and those without-COVID-19.Methods 31 SSNHL patients with COVID-19 who were hospitalized in a department during the COVID-19 epidemic period(from December 2022 to January 2023)were included as the study group,and 12 SSNHL patients without COVID-19 who received treatment during the non-COVID-19 epidemic period(from December 2021 to January 2022)were co-llected as the control group.Two groups of patients received standardized treatment,and their clinical characteristics and prognosis were compared.Clinical characteristics of SSNHL patients with COVID-19 during the COVID-19 epidemic period were analyzed.Results The time interval from patients developed COVID-19 to the onset of SSNHL in the study group was 3-30 days.The time interval from onset to consultation were 3(1,7)days and 5(4,6)days in the study group and the control group,respectively,with no significant difference(P＞0.05).The average age of patients in the study group was(44.16±13.54)years,which was higher than that of the control group(35.23±9.24)years,and the difference was statistically significant(P＜0.05).The hearing at damaged fre-quency of the study group improved by 6.5(0.5,24.5)dB after therapy,which was lower than that of the control group(36.0[27.0,38.0]dB),with statistically significant difference(P＜0.05).There was a negative correlation of the interval of consultation with the average improvement level of hearing at damaged frequency(r=-0.318,P=0.033).The longer the interval,the less the hearing improvement and the worse the therapeutic effect.Corre-lation analysis was further conducted on the time interval from development of COVID-19 to SSNHL onset and the time interval of consultation in patients in the study group,which showed no correlation(r=-0.337,P=0.059).There was no statistically significant difference in the types and degree of SSNHL between two groups of patients(both P＞0.05).After standardized treatment,the rate of ineffective patients in the study group was 56.25％,which was higher than that in the control group(15.38％),and the difference was statistically significant(P＜0.05).Conclusion After adjusting the COVID-19 prevention and control policies,there are more hospitalized COVID-19 patients with SSNHL,with a higher proportion in patients of older age,with poorer efficacy,and inef-fective treatment.The earlier the treatment for SSNHL patients,the better the effect can achieve.COVID-19 may be a potential inducement and/or etiological factor of SSNHL,and further research is needed.

Medical studies have found that tumor mutation burden (TMB) is positively correlated with the efficacy of immunotherapy for non-small cell lung cancer (NSCLC), and TMB value can be used to predict the efficacy of targeted therapy and chemotherapy. However, the calculation of TMB value mainly depends on the whole exon sequencing (WES) technology, which usually costs too much time and expenses. To deal with above problem, this paper studies the correlation between TMB and slice images by taking advantage of digital pathological slices commonly used in clinic and then predicts the patient TMB level accordingly. This paper proposes a deep learning model (RCA-MSAG) based on residual coordinate attention (RCA) structure and combined with multi-scale attention guidance (MSAG) module. The model takes ResNet-50 as the basic model and integrates coordinate attention (CA) into bottleneck module to capture the direction-aware and position-sensitive information, which makes the model able to locate and identify the interesting positions more accurately. And then, MSAG module is embedded into the network, which makes the model able to extract the deep features of lung cancer pathological sections and the interactive information between channels. The cancer genome map (TCGA) open dataset is adopted in the experiment, which consists of 200 pathological sections of lung adenocarcinoma, including 80 data samples with high TMB value, 77 data samples with medium TMB value and 43 data samples with low TMB value. Experimental results demonstrate that the accuracy, precision, recall and F1 score of the proposed model are 96.2%, 96.4%, 96.2% and 96.3%, respectively, which are superior to the existing mainstream deep learning models. The model proposed in this paper can promote clinical auxiliary diagnosis and has certain theoretical guiding significance for TMB prediction.

Objective To compare the clinical efficacy and safety of carbon dioxide (CO2) versus high-frequency electroacupuncture based on the assistance of drilling and blunt dissection in the treatment of steatocystoma multiplex.Methods A randomized,self-controlled study was performed in 15 patients.The median line of the body served as the dividing line,and the lesions on the two sides of the median line of the body were randomly divided into 2 groups to be treated with CO2 laser or high-frequency electroacupuncture,which left micropathways into the cyst cavity.After the above treatment,contents in the cysts were squeezed out or drawn out with a mosquito clamp,and the cysts were bluntly dissected.The decrustation time,erythema subsiding time,adverse reactions and recurrence were compared among lesions at different sites or with different sizes.Results For the lesions at the same sites or with similar sizes after treatment,the decrustation time and erythema subsiding time were both significantly shorter in the CO2 laser group than in the high-frequency electroacupuncture group (both P ＜ 0.05).There were significant differences in the decrustation time and erythema subsiding time among lesions at different sites or with different sizes (all P ＜ 0.05).Mild pain occurred in the 2 groups,and no hematoma or secondary infection occurred.There were significant differences in the incidence of scar formation or pigmentation between the 2 groups (both P ＜ 0.05).During the follow-up of 6-18 months,relapse occurred in 1 patient in each group.Conclusion Compared with the high-frequency electroacupuncture,CO2 laser assisted by drilling and blunt dissection shows better efficacy in the treatment of steatocystoma multiplex,and it can remove lesions at various sites at one time.

Objective To investigate the effect of vacuum-assisted closure(VAC)on the circulating number of endothelia progenitor cell(EPCs)in diabetic patients with mild to moderate degrees of ischemic foot ulcer and their related factors. Methods A total of 84 diabetic patients with foot ulcer duration for at least 4 weeks and ankle brachial index(ABI)0.5~0.9 were selected and divided into and assigned to two groups according to 2: 1 randomization:vacuum-assisted closure(VAC)treatment group(n=56)and Non-VAC treatment group(n=28). The control group (NC) was composed of 18 patients who had normal glucose tolerance and lower extremity ulcer without arteriovenous disease. VAC was performed on the ulcer wound after debridement for 1 week in both VAC group and NC group,and the patients in Non-VAC group received conventional treatment process. The circulating number of EPCs was measured before and after various treatments and the influencing factors of their changes were analyzed. Results After VAC treatment,the circulating number of EPCs significantly increased in both VAC group and NC group[(85.3 ± 18.1)vs(34.1 ± 12.5)/106cells,(119.9 ± 14.4)vs(66.1 ± 10.6)/106cells,both P<0.05]. By contrast,the circulating number of EPCs had no significant change in Non-VAC group[(45.2 ± 19.4)vs(34.7 ± 16.8)/106cells, P>0.05]. In addition,the circulating levels of vascular endothelial growth factor(VEGF)and the protein expressions of VEGF and stromal cell-derived factor-1α(SDF-1α)in the granulation tissue also significantly increased after VAC treatment in both VAC group and NC group,but no significant change in Non-VAC group. Compared with Non-VAC group,the changes of VEGF and SDF-1α levels in the sera and granulation tissue were all significantly higher in both VAC group and NC group(P<0.05 or P<0.01). There were no significant differences in changes of the circulating number of EPCs, and VEGF and SDF-1α in the sera and granulation tissue between VAC group and NC group. Correlation analysis showed that the change of the circulating number of EPCs was correlated with the changes of VEGF and SDF-1α levels in the sera and granulation tissue of VAC group and NC group(P<0.05). Conclusion VAC treatment may increase the circulating number of EPCs in diabetic patients with mild to moderate ischemic foot ulcer as in non-diabetic controls,which may be attributed to the upregulation of systemic and local VEGF and SDF-1α levels.
