Abstract
Laryngeal squamous cell carcinoma (LSCC) is currently a serious public health problem in China; thus, it is urgent to identify effective treatment strategies for this disease. Previous studies demonstrated that reactive oxygen species (ROS) serve important roles in the apoptosis of LSCC cells. It has also been indicated that carboplatin (CBDCA), a second-generation platinum compound with broad antineoplastic properties, is able to induce oxidative stress to produce ROS, which in turn promotes apoptosis. Thus, the present study investigated if CBDCA is cytotoxic in LSCC cells due to the oxidative stress caused by ROS. Therefore, an MTT assay was performed to determine the cell viability of HN-3 LSCC cells following treatment with different doses of CBDCA. Subsequently, the expression levels of ROS and the rate of apoptosis/necrosis were evaluated in the cells. Following this, the HN-3 cells were co-treated with CBDCA and glutathione (GSH) or H2O2, followed by an MTT assay, a cell migration assay and western blot analysis. The results demonstrated that CBDCA reduced the viability of HN-3 cells in a time- and dose-dependent manner and promoted the production of ROS and apoptosis at certain doses. Additionally, the combination treatment of CBDCA and H2O2 enhanced the inhibitory effects of CBDCA on cell viability and migration ability, and promoted apoptosis in HN-3 cells; whereas the combined treatment of CBDCA and GSH exerted opposite effects. The results of the present study demonstrated that CBDCA promotes the apoptosis of HN-3 cells through accumulation of ROS, which may provide a novel treatment strategy for treating LSCC.

Abstract
Effects of maternal aging on the offspring cognitive function remain controversial in population-based investigations, and information available in animal studies is very limited. We investigated the impact of a delayed first natural pregnancy on pregnancy outcomes in the mouse model. Spatial learning capacity in young adult mouse offspring was observed by step-down passive avoidance task and Morris water maze (MWM). Maternal serum α-klotho was measured by ELISA. Morphological characteristics of fetoplacental unit and offspring brain were identified by H&E and immunohistochemistry. Klotho, VDR and other related genes expression were quantified by real-time-RT-PCR and western blot. We found delayed pregnancy reduced fertility in female mice by three-fold (Young vs. Old: 5.0% vs. 20.7%), and increased adverse pregnant outcomes by eight-fold (Young vs. Old: 3.0% vs. 27.5%). Mice born to old mothers exhibited shorter retention trial latency in passive avoidance task and longer latency to find the platform in MWM, suggesting worse performance on the tests that measure learning and memory. Serum α-klotho level was lower in old female mice before pregnancy, whereas became comparable after pregnancy. Vitamin D receptor (VDR) expression, both in mRNA and protein, markedly decreased during the early stage of fetoplacental unit in old mice, especially in trophoblast giant cells when compared with that of young mice. Importantly, consistent with fetoplacental unit, VDR expression also declined in hippocampus from offspring born to old mice. These results suggest that young adult offspring from aged mothers exhibited worse cognitive function and the reduced VDR expression during fetoplacental development might play an important role.

Abstract
Maximizing the effectiveness of prescriptions and minimizing adverse effects of drugs is a key component of the health care of patients. In the practice of traditional Chinese medicine (TCM), it is important to provide clinicians a reference for dosing of prescribed drugs. The traditional Cheng-Church biclustering algorithm (CC) is optimized and the data of TCM prescription dose is analyzed by using the optimization algorithm. Based on an analysis of 212 prescriptions related to TCM treatment of kidney diseases, the study generated 87 prescription dose quantum matrices and each sub-matrix represents the referential value of the doses of drugs in different recipes. The optimized CC algorithm can effectively eliminate the interference of zero in the original dose matrix of TCM prescriptions and avoid zero appearing in output sub-matrix. This results in the ability to effectively analyze the reference value of drugs in different prescriptions related to kidney diseases, so as to provide valuable reference for clinicians to use drugs rationally.

Abstract
Objective: To evaluate the effect of lung transplantation for phase Ⅲ silicosis. Methods: From September 2002 to September 2015, 32 patients with end-stage silicosis underwent lung transplantation at Department of Thoracic Surgery, Affiliated Wuxi People's Hospital, Nanjing Medical University. There were 29 male and 3 female patients aged from 24 to 63 years. Thirty-two patients were diagnosed as phase Ⅲ silicosis by the local occupational disease prevention and control center. Fifteen patients were type Ⅰ respiratory failure and 17 patients were type Ⅱ. There were 14 cases accepted bilateral sequential lung transplantation and 18 cases accepted single lung transplantation, including 13 cases with right single lung transplantation and 5 cases with left single lung transplantation. Extracorporeal membrane oxygenation was used in 13 patients. Pulmonary function monitoring was performed at 3 months, 6 months, 1 year, and 2 years after lung transplantation. Clinical characteristics were compared using t-test, χ2 test and Fisher exact test between groups, Kaplan-Meier survival curve and Log-rank test were used to find out the factors affecting survival. Results: All the patients received lung transplantation successfully. One patient died of multiple organ failure, 1 died of sepsis, and 1 succumbed to sudden cardiac death. Twenty-nine patients were discharged from hospital. During follow-up, there were 5 deaths, two patients died of sepsis 7 months postoperatively, 1 died of renal failure 5 months post-transplant, 1 died of sudden cardiac death, and the remaining 1 patient died of bronchiolitis obliterans. Twenty-four patients lived a good quality of life, with survival rates of 90.6% at 3 months, 80.8% at 1 year, 76.7% at 3 years, and 76.7% at 5 years. Significant difference was not observed between single and bilateral lung transplantation about long-term survival rate. During follow-up pulmonary function post-transplant (3 months, 6 months, 1 year, and 2 years) were improved dramatically compared with preoperative level, and patients lived a good quality of life. Conclusion: Lung transplantation is beneficial for patients with phase Ⅲ silicosis, long-term survival is probable.

Abstract
Air pollution has been classified as Group 1 carcinogenic to humans, but the underlying tumorigenesis remains unclear. In Xuanwei City of Yunnan Province, the lung cancer incidence is among the highest in China attributed to severe air pollution generated by combustion of smoky coal, providing a unique opportunity to dissect lung carcinogenesis of air pollution. Here we analyzed the somatic mutations of 164 non-small cell lung cancers (NSCLCs) from Xuanwei and control regions (CR) where smoky coal was not used. Whole genome sequencing revealed a mean of 289 somatic exonic mutations per tumor and the frequent C:G → A:T nucleotide substitutions in Xuanwei NSCLCs. Exome sequencing of 2010 genes showed that Xuanwei and CR NSCLCs had a mean of 68 and 22 mutated genes per tumor, respectively (p < 0.0001). We found 167 genes (including TP53, RYR2, KRAS, CACNA1E) which had significantly higher mutation frequencies in Xuanwei than CR patients, and mutations in most genes in Xuanwei NSCLCs differed from those in CR cases. The mutation rates of 70 genes (e.g., RYR2, MYH3, GPR144, CACNA1E) were associated with patients' lifetime benzo(a)pyrene exposure. This study uncovers the mutation spectrum of air pollution-related lung cancers, and provides evidence for pollution exposure-genomic mutation relationship at a large scale.
