OBJECTIVE To study the relationship between the methods of CPAP pressure titration (under whole night PSG or by auto-set) and CPAP compliance. METHODS Forty-five patients with serious OSAHS who had been diagnosed in our sleep lab between 2001 and 2004 and were willing to try CPAP treatment were enrolled. They were divided into A and B group according to their wills: pressure titration under whole night PSG in lab (group A) or by auto-set in their families (group B). After pressure titration, patients and their families were educated for the knowledge of CPAP treatment in OSAHS patients. Questionnaires about QOL before CPAP treatment and half year later were carried out on the phone. The decreased score was used to evaluate the effect of CPAP treatment. The hours of per day using machine were used to evaluate the compliance of CPAP. RESULTS Group A and group B got the similar decreased score (14 VS 14.3) , compliance (4.91h VS 4.97h) and adherence (85.7 % VS 88 %) . CONCLUSION OSAHS patients under go pressure titration either in lab with PSG or in their home with auto-set have the same effect and same compliance of CPAP treatment. That means the simple auto-titration can substitute the traditional titration under whole night in lab.

Emotion recognition will be prosperious in multifarious applications, like distance education, healthcare, and human-computer interactions, etc. Emotions can be recognized from the behavior signals such as speech, facial expressions, gestures or the physiological signals such as electroencephalogram and electrocardiogram. Contrast to other methods, the physiological signals based emotion recognition can achieve more objective and effective results because it is almost impossible to be disguised. This paper introduces recent advancements in emotion research using physiological signals, specified to its emotion model, elicitation stimuli, feature extraction and classification methods. Finally the paper also discusses some research challenges and future developments.

Objective To explore the causes of readmission after prostatectomy for BPH and to discuss the treatment approaches. Methods A total of 106 cases who were eligible for the study were reviewed.47 cases had residual and recurrent adenoma;of these cases,42 underwent TURP and 5 open prostatectomy again.32 cases developed urethral stricture;of these cases 27 underwent transurethral cold knife incision plus electric resection of scar and 3 urethral orifice reconstruction and 2 suprapubic cystostomy.11 cases who had experienced bleeding after TURP underwent transurethral bladder washing and coagulating.7 cases had neuropathic bladder dysfunction;of these cases 2 underwent transurethral bladder neck circle muscle resection,3 intermittent self-catheterization and 2 suprapubic cystostomy.6 cases had prostatic cancer;of these cases 1 underwent radical prostatectomy,3 palliative TURP plus orchiectomy and 2 orchiectomy.2 cases had incontinence after TURP;of the 2 cases 1 used external collecting device and 1 was transfered to other hospital for surgery.1 case had abdominal incision hernia and then underwent hernia repair. Results Among 106 cases, 97 cases underwent operations and of them 84 (86.6%) cases achieved successful results.The follow-up time was 6 months to 15 years with a mean of 5 years and 8 months.9 cases with urethral stricture required regular urethral dilation after surgery.4 cases who had had unsuccessful surgery underwent suprapubic cystostomy.Other 9 cases did not undergo operations due to poor health and other reasons. Conclusions Correct preoperative diagnosis, rational surgical type and adequate intraoperative and postoperative management are key to preventing readmission. Transurethral surgery is most favorable treatment choice for readmitted patients after prostatectomy for BPH.
