To analyze subtypes of the clinical presentation of moderate-to-severe obstructive sleep apnea syndrome (OSAS) by cluster analysis and to explore its significance.A retrospective analysis was performed on the data of adult moderate-to-severe OSAS patients, which were diagnosed in Respiratory Department, Renmin Hospital of Wuhan University from October 2012 to October 2015. Fifteen kinds of clinical presentations were included in the cluster analysis, and analysis of characteristic of each cluster was then performed after category.Patients were classified as three distinct clusters. They were identified as "daytime sleepiness group" , "night insomnia group" and "minimally symptomatic group" , consisting of 450 cases (44.64%), 351 cases (34.82%) and 207 cases (20.54%) of the entire cohort. Members in daytime sleepiness group had the highest probability of daytime sleepiness, tiredness, irritableness and the highest Epworth Sleeping Scale score[329 cases (73.11%), 280 cases (62.22%), 223 cases (49.56%) and (13.50±4.93) points], members in night insomnia group had the highest probability of complaining of insomnia, nocturia, night sweats, apnea and awakening[177 cases (50.43%), 157 cases (44.73%), 130 cases (37.04%), 296 cases (84.33%), 182 cases (51.85%)], the probability of having typical symptoms above was the lowest in minimally symptomatic group, but these patients were more likely to have related comorbidities: hypertension, coronary heart disease, arrhythmia, chronic obstructive pulmonary disease and gastroesophageal reflux disease[118 cases (57.00%), 41 cases (19.81%), 44 cases (21.26%), 34 cases (16.43%), 38 cases (18.36%)]; all above results were significantly higher than the other two groups (P0.012 5). The rate of diabetes in minimally symptomatic group[28 cases (13.53%)]was also higher but the difference was not statistical significance.Cluster analysis contributes to classify multiple clinical presentations of OSAS patients, which has important significance for recognizing disease heterogeneity and early diagnosis.

To explore the safety of laparoscopic assisted radical resection of colon cancer in uremic patients.Retrospective analysis of Zhejiang Jinhua Guangfu hospital 2012 March to 2015 March 5 cases of uremia patients complicated with colon cancer underwent laparoscopic assisted colorectal cancer radical resection, and compared with 10 cases, observing two groups of operative time, intraoperative bleeding volume, postoperative drainage volume, lymph nodes dissect, anal exhaust time, postoperative complications, postoperative hospitalization time and postoperative pathological staging.Before operation two groups of age, gender, tumor location was no significant difference (P0.05). In preoperative comorbidities uremic patients were significantly more than that of ordinary patients, mainly in cardiovascular complications, and patients in the two groups in operation time, intraoperative bleeding, post operative drainage volume, lymph node dissection numbers were no significant difference, the postoperative gastrointestinal function recovery was almost no difference, but postoperative hospitalization time significantly prolonged (P0.05).Patients with uremia as long as full preoperative preparation, perioperative management, plus timely hemodialysis, uremia patients undergoing laparoscopic assisted radical surgery is safe and feasible, and it is worth promoting.

To explore the therapeutic effect and quality of life in elderly patients of muscle-invasive bladder cancer by transurethral resection combined with intravesical instillation therapy.From January 2005 to January 2015, 136 cases were diagnosed with T2 bladder cancer by transurethralplasmakinetic therapy or transurethral laser therapy. The data of 136 cases were analyzed retrospectively.In transurethralplasmakinetic therapy group, the overall survival rate was 73.3%, the cancer-specific survival rate was 85.6%, the average survival time were 65 months. In transurethral laser therapy group, the overall survival rate was 73.9%, the cancer-specific survivalrate was 87.2%, the average survival time were 70 months. Two methods also can improve the patient's quality of life.For the aged with invasive bladder cancer (T2), we could try the transurethral resection combined with intravesical instillation therapy.
