OBJECTIVES Recent guidelines have revealed that allergic rhinitis (AR) impairs quality of life. Neuropeptides play a central role in AR. The aim of this study was to determine the efficacy of posterior nasal neurectomy (PNN) for the treatment of AR and for the suppression of neuropeptides and type 2 cytokine expression. METHODS In total, 77 patients undergoing PNN were recruited. Subjective symptoms, including sneezing and rhinorrhea, were elicited with a questionnaire using a 10 cm visual analogue scale (VAS). Nasal lavage fluid taken from a random sample of 17 patients both preoperatively and 1 year postoperatively was screened with enzyme-linked immunosorbent assays. RESULTS Postoperative rhinorrhea (6.03 ± 1.31vs 2.12 ± 1.40, P  less then  0.001) and sneezing (5.53 ± 1.25vs 2.04 ± 1.29, P  less then  0.001) were significantly improved relative to the preoperative levels; the mean SP and NPY concentrations in the nasal lavage fluid were 91.6 ± 20.9 pg/ml and 71.5 ± 10.5 pg/ml, which decreased significantly to 52.9 ± 16.7 pg/ml and 31.8 ± 8.2 pg/ml, respectively, and the mean periostin and IL-5 concentrations were 215.2 ± 87.7 pg/ml and 984.5 ± 181.8 pg/ml, which decreased significantly to 146.1 ± 70.1 pg/ml and 281.6 ± 74.0 pg/ml, respectively. CONCLUSIONS PNN was safe and well tolerated, and the symptom (sneezing and rhinorrhea) scores were significantly decreased by 1 year postoperatively. BACKGROUND Melanoma is one of the most aggressive, therapy-resistant skin cancers in the world. Hydrogen sulfide (H2S), a newly discovered gasotransmitter, plays a crucial role in the progression and development of many types of cancers. However, the effect of H2S on human skin melanoma remains to be elucidated. OBJECTIVE We aimed to explore the effect of exogenous H2S on melanoma cells and its underlying mechanisms. METHODS In this study, human skin melanoma cell lines, including A375 and SK-MEL-28, were treated with a donor of H2S (NaHS). CCK-8, scratch assay, flow cytometric analysis, western blotting and transmission electron microscopy (TEM) were performed to explore the effects of H2S on cell behaviors. RESULTS Treatment with NaHS inhibited cell proliferation, migration and division, while it could induce cell apoptosis and autophagy in melanoma cell lines. Moreover, NaHS significantly decreased the expression of p-PI3K, p-Akt and mTOR proteins. Furthermore, insulin-like growth factor-1 (IGF-1), the activator of PI3K/AKT/mTOR pathway, could reverse the cell behaviors caused by NaHS. CONCLUSION Our results demonstrated that exogenous hydrogen sulfide could inhibit human melanoma cell development via suppression of the PI3K/AKT/mTOR pathway. Hydrogen sulfide might serve as a potential therapeutic option for melanoma. The aim of this retrospective study was to assess the clinical and aesthetic outcomes, and patient satisfaction, following dental implant therapy in cleft patients. Implant survival, changes in marginal bone level, pocket probing depths, plaque and bleeding indices, aesthetics, and patient satisfaction were assessed in 17 alveolar cleft patients and 17 matched controls. At follow-up (mean 72.4±46.4 months), one implant had been lost in the cleft group. Mean marginal bone loss at follow-up was -0.4±0.4mm in cleft patients and -0.2±0.4mm in controls. Aesthetics of the peri-implant soft tissues (pink aesthetic score) were less favourable (P=0.025) in cleft patients (5.0±1.9) than in controls (6.5±1.7), while peri-implant parameters were comparable in the two groups. Overall patient satisfaction was 8.6±0.9 in cleft patients and 8.9±1.1 in controls (P=0.331). In cleft patients, no difference in aesthetics was observed between patients who received additional bone augmentation at 3 months prior to implant placement and those who did not (P=0.092). Dental implant therapy in cleft patients is associated with high implant survival, minor marginal bone loss, healthy peri-implant soft tissues, and high patient satisfaction. Only the aesthetics of the soft tissues was worse in cleft patients compared to augmented non-cleft patients. The use of peripheral nerve blockade for hip surgeries has proved to be beneficial. Nirogacestat in vivo The PEricapsular Nerve Group block is a new technique described for hip fracture and hip arthroplasty that has shown to provide better analgesia compared to other peripheral blocks commonly performed for this type of surgery. This technique blocks the obturator nerve and the articular branches of the femoral nerve and the accessory obturator nerve. There are few reports describing continuous analgesia using catheters inserted in the pericapsular nerve group area. We describe a case of continuous nerve block for preoperative analgesia that lasted up to 120hours in an adult patient with a fracture of the posterior column and wall of the acetabulum. We found that by increasing the infusion rate, analgesia reached the distal femoral area. Unlike the original technique, a high-frequency linear probe was used in this case. Cervical cancer continues to be a prevalent diagnosis among gynecologic pathology despite widespread screening methods and known pathogenesis by human papilloma virus. We describe a patient who underwent next generation sequencing (NGS) of her high grade squamous dysplasia (HG-SIL) as well as the invasive component of her cervical cancer. This tumor showed an amplification of PIK3CA in the invasive carcinoma in addition to a common E542K mutation both in dysplastic and invasive carcinoma. The dysplasia also showed a novel PCNX (e1) - RAD51B (e8) fusion suggesting potentially new mechanisms of pathogenesis in cervical squamous cell carcinoma. BACKGROUND Our previous study states that propofol suppresses proliferation and migration of papillary thyroid cancer (PTC) cells by downregulation of lncRNA ANRIL. This study intended to probe the downstream mechanism of ANRIL in PTC with potential microRNAs (miR) and genes. METHODS ANRIL expression was detected in normal thyroid epithelial cells (Nthy-ori 3-1) and PTC cells (TPC-1, FTC-133, K1 and BCPAP). ANRIL expression was inhibited in TPC-1 and BCPAP cells to explore the effects of si-ANRIL in PTC malignant behaviors. The gain-and loss-of functions of ANRIL/miR-320a were performed to measure their roles in PTC. Levels of ANRIL, miR-320a, HMGB1, apoptosis- and Wnt/β-catenin and NF-κB pathways-related proteins were measured. Dual-luciferase reporter gene assay and RNA pull-down assay were applied to verify ANRIL/miR-320a/HMGB1 relation. si-ANRIL was transplanted into xenograft tumors in nude mice. RESULTS ANRIL was upregulated in TPC-1 and BCPAP cells. miR-320a targeted HMGB1, and ANRIL bound to miR-320a.
