[Source Analysis and Health Risk Assessment of PAHs in PM During Winter in Liaocheng City].

To investigate the mass concentrations, sources, and health effects of polycyclic aromatic hydrocarbons (PAHs) in ambient particulate matter (PM) in Liaocheng City during winter, 14 types of PAHs in PM were determined from January to February of 2017. The sources of the PAHs were analyzed by using diagnostics ratios and the principal component analysis (PCA)-multiple linear regression (MLR) model,and the health risk of PAHs was assessed by BaP equivalent concentrations (BaP) and incremental lifetime cancer risk (ILCR). The results showed that the mass concentrations of PAHs in PM during winter were (64.

Diphenyleneiodonium Mitigates Bupivacaine-Induced Sciatic Nerve Damage in a Diabetic Neuropathy Rat Model by Attenuating Oxidative Stress.

Background: Increased oxidative stress has been linked to local anesthetic-induced nerve injury in a diabetic neuropathy (DN) rat model. The current study explores the effects of diphenyleneiodonium (DPI) chloride, an NADPH oxidase (NOX) inhibitor, on bupivacaine-induced sciatic nerve injury in DN rats.

Methods: A rat DN model was established through high-fat diet feeding and streptozotocin injection.

[Effects of environmental and biotic factors on soil respiration in a coastal wetland in the Yellow River Delta, China.].

Using the Li-8150 multichannel automatic soil CO efflux system, soil respiration was measured continuously over a one-year period in a coastal wetland in the Yellow River Delta, China. Environmental and biological factors were measured simultaneously, including temperature, soil water content, aboveground biomass and leaf area index. The results showed that the diurnal variation of soil respiration presented a single-peak curve, but it appeared as multiple peaks when disturbed by soil freezing and surface flooding.

Hypothetic association between greater sympathetic activity and prostate cancer.

Among men, prostate cancer is the most common cancer diagnosed, and the second leading cause of death from cancer in the industrialized countries. In spite of substantial progress in research, diagnosis and treatment, the causes of prostate cancer remain largely unknown. In this paper, we propose the hypothesis that prostate cancer represents another entity in the constellation of disease incited by the greater sympathetic activity that develops with age.

[Urethroplasty with tunica vaginalis flap for treating hypospadias with hydrocele: a report of 9 cases].

Objective: To explore the treatment of hypospadias with hydrocele.

Methods: Nine patients with hypospadias complicated by hydrocele underwent urethroplasty with tunica vaginalis flap.

Results: Satisfactory results were achieved in 7 cases, all with a normal anatomic position of urethral meatus, perfect urination and no infection.

[Expression of Ki-67, Bcl-2,Bax and caspase-3 in benign prostatic hyperplasia combined with prostatitis and their significances].

Objective: To detect the expression of Ki-67, Bcl-2, Bax and caspase-3 in simple benign prostatic hyperplasia (BPH) and BPH combined with prostatitis,and to evaluate the effect of inflammation on the development and progression of BPH.

Methods: All specimens were obtained from patients undergoing surgical resection of the prostate. The paraffin section of the specimens was stained with hemotoxyline and eosin, and observed under light microscope to examine the inflammation hispathological changes.

Chronic inflammation in benign prostatic hyperplasia: implications for therapy.

Benign prostatic hyperplasia (BPH) is a common age related proliferative abnormality of the human prostate. Histological features demonstrate that the typical nodules of BPH are composed of stromal and epithelial cells that are proportionally different between nodules. BPH nodules frequently occur concurrently with chronic inflammatory infiltrates, mainly composed of chronically activated T cells and macrophages.

[The efficacy and safety in the treatment of chronic abacterial prostatitis/chronic pelvic pain syndrome after intraprostatic injection of Chuanshentong].

Objective: To assess the clinic efficacy and safety in the treatment of chronic abacterial prostatitis/chronic pelvic pain syndrome (CABP/CPPS) after intraprostatic injection of Chuanshentong.

Methods: Five milliliter of solution blending Chuanshentong and lidocaine was transperineally injected into one lobe of prostate, once a day for 6 days, for a total of 98 cases of patients who had been diagnosed as chronic abacterial prostatitis/chronic pelvic pain syndrome. The efficacy was evaluated by the NIH Chronic Prostatitis Symptom Index (CPSI) after a 12 week follow-up.
