Selective recovery of lithium and iron phosphate/carbon from spent lithium iron phosphate cathode material by anionic membrane slurry electrolysis.

A simple, green and effective method, which combined lithium iron phosphate battery charging mechanism and slurry electrolysis process, is proposed for recycling spent lithium iron phosphate. Li and FePO can be separation in anionic membrane slurry electrolysis without the addition of chemical reagent. The leaching efficiency of Li can reach to 98% and over 96% of Fe are recycled as FePO/C.

Application of self-retaining bidirectional barbed absorbable suture in retroperito- neoscopic partial nephrectomy.

Objective: To investigate the safety and feasibility of self-retaining bidirectional barbed absorbable suture application in retroperitoneoscopic partial nephrectomy.

Materials And Methods: From Sep 2011 and Aug 2012, 76 cases of retroperitoneoscopic partial nephrectomy were performed at our hospital. The patients were divided into two groups: self-retaining barbed suture (SRBS) group (n = 36) and non-SRBS group (n = 40).

Inguinal incision as a successful route to extract the kidney during laparoscopic retroperitoneal live-donor nephrectomy.

Objectives: We sought to evaluate the advantages of an inguinal incision in extracting the kidney during retroperitoneal laparoscopic live-donor nephrectomy.

Materials And Methods: From May 2008 to June 2011, fifty-eight cases of retroperitoneal live-donor nephrectomy were performed at our hospital; all data were analyzed retrospectively. All donors were grouped in a test group (n=32, inguinal incision) or a control group (n=26, lumbar incision) according to the selected graft retrieval incision.

MicroRNA expression profile analysis reveals diagnostic biomarker for human prostate cancer.

Prostate cancer is a highly prevalent disease in older men of the western world. MicroRNAs (miRNAs) are small RNA molecules that regulate gene expression via posttranscriptional inhibition of protein synthesis. To identify the diagnostic potential of miRNAs in prostate cancer, we downloaded the miRNA expression profile of prostate cancer from the GEO database and analysed the differentially expressed miRNAs (DE-miRNAs) in prostate cancerous tissue compared to non-cancerous tissue.

[Study on severity, status of awareness and therapy regarding urinary incontinence in elderly people from rural areas in Jixian county, Tianjin].

Objective: To understand the prevalence of urinary incontinence (UI) and its severity in rural elderly people, as well as to investigate the awareness on UI in the elderly and health-care service seeking behavior.

Methods: A cross-sectional study was carried out in two townships of Jixian county, Tianjin. A total of 743 people aged 60 years and over were selected under cluster sampling method.

[Study on the prevalence of urinary incontinence and its related factors among elderly in rural areas, Jixian county, Tianjin].

Objective: To understand the prevalence of urinary incontinence (UI) and its related factors so as to develop a three-tier program for prevention of the disease.

Methods: A cross-sectional study was carried out in two townships of Jixian county, Tianjin, during July to November 2007. A total of 743 people aged 60 years and over were selected under cluster sampling, and all information were collected with a standardized structured questionnaire by face-to-face interview.

[Outcomes of renal transplantation with donor kidneys with multiple arteries].

Objective: To compare the outcomes of renal transplantation with donor kidneys with multi-branched renal arteries.

Methods: The data about operation time, volume of intra-operational blood loss, postoperative complications, and post-operational renal function status of 251 recipients of donor kidneys with single-branched renal artery (Group A), 12 recipients of donor kidneys with double-branched renal arteries the diameter of one of which was < 2 mm or the estimated blood supply areas of one of which were < 10% (Group B), and 35 recipients of donor kidneys with renal arteries with 2 or more than 2 branches (Group C).

Results: The operation time was (115 +/- 34) min in Group A and was (120 +/- 31) min in Group B, both shorter than that of Group C [(133 +/- 55) min], however, not significantly.
