[Progress in home uroflowmetry in evaluation of lower urinary tract symptoms in patients].

Uroflowmetry is the most widely used non-invasive urodynamic tool for most patients with suspected lower urinary tract dysfunction. Home uroflowmetry can produce multiple representative flow readings in adequate privacy condition when patients feel a normal desire. Because of its advantages of decreasing variability, describing circadian rhythms and combating problems inherent to clinic-based measurements, it can improve diagnostic accuracy and predictive value.

[Ketamine-associated urinary tract damage].

Ketamine is widely used as an anesthetic during surgical procedures in both animals and humans. As its unique effects of inducing the dissociative hallucinatory,vivid dreams, out-of-body experiences, and delirium, it has diverted from legitimate uses to the illicit drug market, and abusing ketamine has become a serious social problem. The abusers may use ketamine alone or mixe it with other drugs to get an intense pleasure.

[Comparison of new portable home electronic uroflowmeter with Laborie uroflowmeter].

Objective: To design a new portable home electronic uroflowmeter and compare it with traditional methods.

Methods: The system consists of collectors, urine conducting apparatus, intelligent cell phone, wireless network communication technology, computer analysis and drawing, and data storage technology, etc., and can automatically collect voiding information from patients with lower urinary tract symptoms(LUTS) Through Bluetooth, the voiding information was sent to the patient's intelligent cell phone from the collector, then stored directly by intelligent cell phone and wirelessly transmitted to the workstation in hospital.

[Age-specific reference ranges for prostate specific antigen in 16 222 Chinese men].

Objective: To investigate the PSA level of 16 222 asymptematic men in Shenzhen who came from different areas of China, in order to find out the PSA levels of Chinese men.

Methods: Serum samples of 16 222 men who came to Peking University Shenzhen Hospital for health examination were collected, all of whom had no symptoms. Their serum PSA levels were measured with MEIA with ILMA instrument.

[Abnormal expression and significance of MIR-184 in human renal carcinoma].

Objective: To explore the role of microRNA-184(MIR-184) in the development of renal cell carcinoma(RCC).

Methods: The expressions of MIR-184 in 51 patients with RCC Investigated, normal adjacent tissues (ADTs) matched by fluorescence quantitative PCR technology (RT-qPCR) and the correlations analyzed between MIR-184 expression and the age, gender and clinical stage of RCC patients.

Results: The average expression of MIR-184 in RCC was -14.

[Advances in clinical study of nocturia].

Nocturia is one of the most common reasons for interrupted sleep in general adult population. The condition affects both men and women, with an incidence that increases dramatically with age. Nocturia has a negative impact on quality of life, affecting both morbidity and mortality.

[Development of remote wireless mobile voiding diary and a report of its objective voiding in 20 young people].

Objective: To find out the data of the micturitions in healthy young people with the remote & mobile voiding diary monitoring system.

Methods: Twenty healthy young people were studied and ten of them were female. The ages ranged from 22 to 35 years (the mean age: 27.
