Sulci cutis connecting to follicular orifices frequently form perifollicular cracks, which join together adjacent sulci. This follicle-sulcus-crack complex (FSCC) is exacerbated by dehydration. Purpose: Although dehydration is associated with facial skin aging, FSCC’s implications in facial skin aging remain unresolved. Method: We measured facial skin parameters in 1999 and 2010 in 108 Japanese women, and in 2006 and 2016 in 182 Chinese women. We addressed whether expansion of FSCC is associated with other skin aging parameters. We also examined whether skin moisturizer can reverse the expanded FSCC. Results: In both clinical studies, FSCC severity as well as wrinkles, spots, and roughness significantly deteriorated with age. Notably, FSCC significantly increased as early as in subjects in their 20s, whereas wrinkles, spots, and roughness became conspicuous in those in their 40s or older. Moreover, subjects with more severe FSCC in the initial measurement exhibited significantly worse wrinkles, spots, and roughness in the second measurement a decade later. Dehydration was significantly correlated with expanded FSCC. Furthermore, FSCC expansion was reversed after appropriate moisturization by daily application of Galactomyces ferment filtrate (GFF)-containing skincare product (SK-II Skin Power Cream) for 4 weeks in 37 women. Conclusion: The expanded FSCC is likely to be an early indicator of facial skin aging. Appropriate moisturization may reduce FSCC formation and decelerate facial skin aging.展开更多

Main outcome measures were preoperative and postoperative visual acuity, and complications both intraoperatively and postoperatively. RESULTS: Review of 22 consecutive patients identified best-corrected visual acuity(BCVA) improvement from 1.37±0.84 to 0.73±0.57 logarithm of the minimal angle of resolution(logMAR) after IOL implantation(P<0.001) with a mean follow-up was 16.55±5.86 mo. Average age at secondary IOL implantation was 41.05±15.41 mo. Three eyes(13.64%) achieved BCVA of 0.3 logMAR at the final visit. Transient intraocular pressure rise(4 eyes; 18.18%), postoperative increased inflammation(3 eyes; 13.64%) and postoperative hypotony(2 eyes; 9.09%) were common complications.CONCLUSION: Properly preservation of the anterior lens capsule during the primary surgery facilitated secondary sulcus IOL implantation in pediatric patients with anterior PFV, with favorable postoperative visual outcomes and compatible percentage of complications.展开更多

Regarding the treatment of patients with locally advanced, resectable NSCLC, several retrospective and prospective studies have shown the significance of multimodality treatments with preoperative chemoradiotherapy and surgical treatment. However, no definitive treatment strategies for locally advanced NSCLC patients have yet been established. One of the reasons for the lack of established treatment strategies for patients with locally advanced NSCLC is considered to be the heterogeneity of the population, i.e., cT4N0, cT3-4N1 and cT1a-3N2 tumors are included in stage IIIA disease, and superior sulcus tumors (SSTs) are also included in this classification. With regard to SST, two representative prospective phase II trials indicated the efficacy of surgical treatment following concurrent radiation and chemotherapy. In a study conducted by the Southwest Oncology Group, 110 patients with superior sulcus NSCLC were treated with two cycles of cisplatin and etoposide concurrently with 45 gray (Gy) of radiation, followed by surgical treatment and two additional cycles of chemotherapy postoperatively. The response rate (RR) to the preoperative chemoradiotherapy was 86%, and 83 patients (76%) were able to undergo complete resection. A pathological complete response (CR) was observed in 61 patients (56%), and the five-year survival of all patients and those undergoing complete resection was 44% and 54%, respectively. A phase II study conducted by the Japan Clinical Oncology Group examined the safety and efficacy of preoperative concurrent chemoradiotherapy using mitomycin, vinblastin and cisplatin followed by surgical treatment. Seventy-six patients with SST were enrolled in this study, and all received chemotherapy using two cycles of MVP concurrently with 45 Gy of radiation, followed by surgery. Neoadjuvant chemoradiotherapy resulted in a 61% RR, and pathological complete resection was successfully achieved in 51 patients (68%). A pathological CR was observed in 12 patients (16%), and the disease-free and overall survival rates at five years were 45% and 56%, respectively. Both studies showed the efficacy and tolerability of the multimodality treatment for SST, thus suggesting that multimodality treatment with preoperative chemoradiotherapy followed by surgery may therefore be an effective treatment for resectable SST. We herein review the results of retrospective and prospective studies while assessing the treatment outcomes of NSCLC patients with SST.展开更多

The sulcus, a structure on the medial side of the otolith, is an important feature in morphological analysis. This study was conducted to evaluate the feasibility of using sulcus morphology for stock identification and to compare its performance with commonly used otolith morphology analysis. Otoliths were collected and analyzed from three geographical groups (the Huanghe (Yellow) River estuary, HHE;the Jiaozhou Bay, JZB;and the Changjiang (Yangtze) River estuary, CJE) of yellow drum Nibea albiflora. The results show that the analysis of sulcus morphology based on shape indices (SIs), elliptic Fourier coefficients (EFc), and a combination of the two parameters identified stocks at overall classification rates of 51.0%, 72.5%, and 73.2%, respectively. These classification rates are similar to those obtained using otolith morphology analysis (57.0%, 73.8%, and 76.5% by SIs, EFc, and their combination, respectively). The findings suggest that sulcus morphology is comparable to the commonly used otolith morphology for identifying stocks of sciaenids, such as the yellow drum. For both otolith and sulcus morphology, EFc could identify the stocks more efficiently than SIs, while the combination of SIs and EFc was even better.展开更多
