Second-Order Nonlinear-Optical-Active Selenide Borate YSeBO: Featuring a [YSeBO] Planar Belt.

Chalcogenide borates were very rarely investigated in the past. As the second selenide borate, YSeBO obtained by a high-temperature solid-state reaction crystallizes in the noncentrosymmetric orthorhombic space group 2 with a novel structure type. Its structure consists of two basic building units, [BO] planar triangles and [YOSe] pentagonal bipyramids, and features the [YSeBO] planar belt.

Establishment of two new predictive models for prostate cancer to determine whether to require prostate biopsy when the PSA level is in the diagnostic gray zone (4-10 ng ml).

Our goal was to establish two new predictive models of prostate cancer to determine whether to require a prostate biopsy when the prostate-specific antigen level is in the diagnostic gray zone. A retrospective analysis of 197 patients undergoing prostate biopsy with prostate-specific antigens between 4 and 10 ng ml was conducted. Of these, 47 patients were confirmed to have cancer, while the remaining 150 patients were diagnosed with benign prostate disease after examining biopsy pathology.

[Prostate Cancer Prevention Trial risk calculator for evaluating the risk of prostate cancer in the high-risk Chinese population].

Objective: The Prostate Cancer Prevention Trial risk calculator (PCPT-RC) is an online tool for assessing the risk of prostate cancer (PCa) based on age, race, serum PSA, biopsy history, family history, and other factors. This study aimed to investigate the value, sensitivity and specificity of the PCPT-RC 2.0 in assessing the risk of PCa in the Chinese high-risk population.

Neurological mechanism of Xiaochaihutang's antidepressant-like effects to socially isolated adult rats.

Objectives: Xiaochaihutang (XCHT) has antidepressant effects in multiple animal models of depression in our previous studies. But the antidepressant effects and exact mechanisms of XCHT in a rat model of chronic social isolation stress (CSIS) have never been studied. We therefore aimed to investigate the effects of XCHT on depressive/anxiety-related behaviours of CSIS-exposed rats and understand the neurological mechanism involving neurogenesis.

Reducing the gastroesophageal reflux with lip-type reinforcement technique during intrathoracic esophagogastrostomy.

Background/aims: Gastroesophageal reflux is a significant problem after esophagogastrostomy, and impact considerably upon the quality of patients' lives. Aims of this study were to evaluate the operative effects in prevention of reflux with lip-type reinforcement during intrathoracic esophagogastric anastomosis.

Methodology: From January 2005 to December 2009, 216 patients received circular stapled esophagogastrostomy with lip-type reinforcement (LR group), and 69 patients with standard reinforcement (SR group) at our hospital.

Chinese herbal medicine for osteoporosis: a systematic review of randomized controlled trails.

Background. Osteoporosis is a major health problem for the elderly population. Chinese herb may be beneficial to osteoporosis due to its capability.

The value of sonoelastography scores and the strain ratio in differential diagnosis of azoospermia.

Purpose: We evaluated the diagnostic performance of real-time elastography for differentiating nonobstructive from obstructive azoospermia.

Materials And Methods: We evaluated 1,192 testes, including 584 with nonobstructive azoospermia, 408 with obstructive azoospermia and 200 controls, from men with a mean ± SD age of 30 ± 5 years. Two radiologists evaluated the testes using a 5-degree elastography score system.

[Quantitative analysis by real-time elastosonography for the differential diagnosis of azoospermia: preliminary application].

Objective: To evaluate the quantitative analysis by real-time elastosonography in the differential diagnosis of obstructive azoospermia (OA) and non-obstructive azoospermia (NOA).

Methods: We evaluated the elastosonographic images of 200 cases of OA, 300 cases of NOA and 100 normal healthy controls, calculated the strain ratio of the testis to the scrotal skin and the median strain ratio among the three groups, and analyzed the best cut-off point for differentiating OA and NOA by the receiver operation characteristic (ROC) curve.

Results: The median strain ratio of NOA was 0.

[Ultrasonographic features of epididymides in obstructive azoospermia].

Objective: To investigate the ultrasonographic features of epididymides in congenital obstructive azoospermia (COA) and acquired obstructive azoospermia (AOA).

Methods: A total of 211 infertile men with obstructive azoospermia were observed by scrotal ultrasonography, and the features of the epididymal ultrasonograms were compared between COA and AOA.

Results: COA exhibited significantly higher rates of ectasia in the epididymal head, cord-like changes, abrupt tapering and absence of the epididymal body and tail than AOA (P < 0.

Chiral diene as the ligand for the synthesis of axially chiral compounds via palladium-catalyzed Suzuki-Miyaura coupling reaction.

The first palladium-diene-catalyzed asymmetric Suzuki-Miyaura coupling reaction has been achieved. A number of functionalized biaryls were obtained in high yields and in moderate to high enantioselectivities. The existence of an ortho-formyl group greatly improves the catalyst efficiency and permits further synthetic elaborations.

[Studies on chemical constituents from Pteris multifida].

Objective: To investigate the chemical constituents of Pteris multifida.

Methods: All compounds were isolated and purified by normal column chromatography, paper thin layer chromatography and sephadex chromatography. The chemical structures were mainly elucidated by ESI mass and NMR spectra.

Highly practical catalytic asymmetric 1,4-addition of arylboronic acids in water using new hydrophilic chiral bicyclo[3.3.0] diene ligands.
