OBJECTIVETo improve the diagnosis and treatment of paratesticular embryonal rhabdomyosarcoma (PER).

METHODSWe retrospectively studied the clinical data of 5 cases of PER treated from 1997 to 2009 and reviewed the relevant literature, focusing on its clinical manifestations, diagnosis and treatment.

RESULTSThe 5 cases of PER, 2 involving the spermatic cord, 2 the testis and 1 the tunica vaginalis, were all treated by radical orchiectomy. Pathologically, 2 cases were classified as stage I, 1 as stage II and 2 as stage IV. Postoperatively, 2 of the patients received chemotherapy and the other 3 refused adjunctive therapy. The patients were followed up for 6, 12, 18 and 28 months, respectively. Four of them remained free from relapse and metastasis, and 1 stage IV patient died of multiple metastasis at 6 months.

CONCLUSIONEarly diagnosis, radical orchiectomy and adjunctive chemo- or radio-therapy are effective means to the treatment of PER.

Objective: To observe the clinical effect of auricle reconstruction in adult patients with microtia and summarize the experience. Methods: Clinical data of adult patients with microtia who underwent total auricle reconstruction using the modified Nagata's two stage for microtia reconstruction from June 2016 to June 2021 were analyzed. A total of 41 adult patients (42 ears) with microtia were enrolled, including 30 males and 11 females, with the median age at the time of surgery of 37 years. Autogenous costal cartilage was used as the auricular framework for all patients in this group. The first stage surgery was performed according to the modified Nagata's two stage for microtia reconstruction procedure,cartilage auricular framework carving was performed by different methods according to the ossification state of adult costal cartilage. Six months following the primary operation, ear elevation and cranioauricular angle formation, retroauricular facial flap transfer and medium-thick skin grafting were performed in the second stage. Results: All patients successfully completed two stage operation. During the follow-up of 3 months and 24 months, all the 41 patients were satisfied with the morphology of reconstructed auricle. Conclusion: According to the costal cartilage status of adult patients, different costal cartilage carving techniques can be used for total auricle reconstruction to obtain ideal surgical results.

Objective To study the effect from different structures and material hardness of orthopedic insoles on flatfoot correction. Methods The contours of flatfoot under weight-bearing and non-weight-bearing conditions were scanned by Infoot system. The 3 kinds of medial longitudinal arch height (typeⅠ, Ⅱ, Ⅲ) and 3 kinds of material hardness (30°, 35°, 42°) from orthopedic insoles were used to compare their effects on flatfoot by the embedded insole test system. Results TypeⅠorthopedic insoles could significantly restore the anatomical position by improving the height of navicular bone, and redistribute the concentrated plantar pressure and increase the loading area of medial longitudinal arch with material hardness of 35°. Conclusions The appropriate insole shows a favorable orthopedic effect to ameliorate the foot deformity of flatfoot patients. The research findings lay a theoretical basis on design of the personalized orthopedic insoles.

BACKGROUND: There is limited information about thymosin α1 (Tα1) as adjuvant immunomodulatory therapy, either used alone or combined with other treatments, in patients with non-small cell lung cancer (NSCLC). This study aimed to evaluate the effect of adjuvant Tα1 treatment on long-term survival in margin-free (R0)-resected stage IA-IIIA NSCLC patients. METHODS: A total of 5746 patients with pathologic stage IA-IIIA NSCLC who underwent R0 resection were included. The patients were divided into the Tα1 group and the control group according to whether they received Tα1 or not. A propensity score matching (PSM) analysis was performed to reduce bias, resulting in 1027 pairs of patients. RESULTS: After PSM, the baseline clinicopathological characteristics were similar between the two groups. The 5-year disease-free survival (DFS) and overall survival (OS) rates were significantly higher in the Tα1 group compared with the control group. The multivariable analysis showed that Tα1 treatment was independently associated with an improved prognosis. A longer duration of Tα1 treatment was associated with improved OS and DFS. The subgroup analyses showed that Tα1 therapy could improve the DFS and/or OS in all subgroups of age, sex, Charlson Comorbidity Index (CCI), smoking status, and pathological tumor-node-metastasis (TNM) stage, especially for patients with non-squamous cell NSCLC and without targeted therapy. CONCLUSION Tα1 as adjuvant immunomodulatory therapy can significantly improve DFS and OS in patients with NSCLC after R0 resection, except for patients with squamous cell carcinoma and those receiving targeted therapy. The duration of Tα1 treatment is recommended to be >24 months.

OBJECTIVE: Psoriasis is a common chronic inflammatory skin disease that is prone to recurrence, and the proinflammatory factor, cysteine-rich protein 61 (Cyr61), is important in its pathophysiology. Long-term clinical practice has shown that Sancao Formula (SC), a Chinese herbal compound, is effective in the treatment of psoriasis, but the precise mechanism remains unknown. In this study, we investigate the mechanism by which SC extract alleviates imiquimod (IMQ)-induced psoriasis. METHODS: The expression of Cyr61 in psoriatic lesions and normal healthy skin was detected using immunohistochemical analysis to investigate the biological role of Cyr61 in models of psoriatic inflammation. A psoriatic mouse model was established by topical application of IMQ, and the effect of topical application of SC extract was evaluated using the psoriasis area and severity index (PASI) score, hematoxylin-eosin staining, and histopathological features of the skin. Next, a HaCaT cell inflammation model was established using interferon-γ (IFN-γ), and the effect of SC extract on the mRNA and protein levels of Cyr61 and intercellular cell adhesion molecule-1 (ICAM-1) was confirmed using Western blot and quantitative real-time polymerase chain reaction analyses. RESULTS: Immunohistochemical staining showed that the expression of Cyr61 in psoriatic lesions was higher than that in normal skin samples (78.26% vs 41.18%, P < 0.05), and the number of Cyr61-positive cells in psoriatic lesions was also significantly higher than in normal skin (18.66 ± 2.51 vs 4.33 ± 1.52, P < 0.05). Treatment in mice with IMQ-induced psoriasis showed that SC extract could significantly improve the inflammatory phenotype, PASI score (10.875 ± 0.744 vs 3.875 ± 0.582, P < 0.05), and pathological features compared with those in IMQ model group; SC treatment was also associated with decreased levels of Cyr61 and ICAM-1. In the IFN-γ-induced inflammatory cell model, the mRNA and protein levels of Cyr61 and ICAM-1 were upregulated, while the SC extract downregulated the levels of Cyr61 and ICAM-1. CONCLUSION The results provide a theoretical basis for the involvement of Cyr61 in the pathogenesis of psoriasis, and suggest that SC should be used to target Cyr61 for the prevention of psoriasis recurrence.
