OBJECTIVETo develop a transparent, non-toxic, non-irritating anti-fogging agent with long-lasting effect for nasal endoscopy.

METHODSThe anti-fogging agent was prepared by mixing ethanol, propylene glycol, polyoxyethylene lauryl ether, sodium dodecyl sulfate, polyethylene glycol 400 and deionized water at different proportions based on an orthogonal test design. Twenty-seven test samples of the anti-fogging agents were obtained, which were colorless, transparent, and non-irritating, with a pH value of 7-8. Storz00 nasal endoscopy and its imaging system were used to test the anti-fogging time of the 27 samples, and each agent was tested for 3 times with medical Seoul iodine and 95% ethanol as control.

RESULTSThe optimal composition of the anti-fogging agent was 20% ethanol, 10% propylene glycol, 20% polyoxyethylene lauryl ether, 4% sodium dodecyl sulfate, 4% polyethylene glycol, 42% deionized water. The anti-fogging time of this agent reached 15 min, significantly longer than that of medical Seoul iodine (4 min) and 95% ethanol (18 s).

CONCLUSIONThis anti-fogging agent for nasal endoscopes is colorless and safe and has a long anti-fogging time by forming a homogenous transparent membrane over the endoscopic lens.

OBJECTIVETo investigate the status of male reproductive health among middle-aged and older men in the urban area of Nanjing.

METHODSWe collected the laboratory results of 884 middle-aged and older men aged 55 - 89 years from the Xuanwu District of Nanjing present for routine physical examinations, including those of blood routine tests, liver and kidney function, blood glucose, blood lipid, and total prostate specific antigen (TPSA), as well as such reproductive hormone indexes as total serum testosterone (TT), free serum testosterone (fT), and sex hormone binding globulin (SHBG). We also obtained the above reproductive hormone indexes from 119 young and middle-aged men aged 20 - 39 years as controls.

RESULTSAging-related changes were found in the 50 percentiles of all the reproductive hormones and relevant parameters but those of TT and E2, with gradual increases in LH, FSH and SHBG and decreases in fT, TSI and fTI. Comparison of reproductive hormones and relevant parameters by Mann-Whitney U test did not show any statistically significant differences in the TT level between any two of the five age groups (20 - 39, 55 - 59, 60 - 69, 70 - 79, and > or = 80 yr) (P > 0.05) except between the control and > or = 80 yr groups and the 60 - 69 and > or = 80 yr groups (P < 0.05), nor in the E2 level between any two groups, nor in the levels of LH and FSH except between the 55 - 59 and 60 - 69 yr groups and the 70 - 79 and > or = 80 yr groups, and nor in the levels of fT and TSI except between the 55 - 59 and 60 - 69 yr groups. However, there were significant differences in the levels of SHBG and fTI between any two age groups. Spearman correlation analysis revealed that fT, TSI, and fTI were correlated negatively with aging and LH (P < 0.05, I r I > 0.5) but weakly positively with cholesterol, blood glucose and hemoglobin (P < 0.05, /r/ < 0.5), SHBG and LH positively with aging, SHBG weakly negatively with blood glucose and hemoglobin, LH weakly negatively with hemoglobin, and TT weakly negatively with aging but positively with hemoglobin.

CONCLUSIONThe levels of serum testosterone, particularly that of fT, declined with aging in middle-aged and older men in the urban area of Nanjing, which may contribute to abnormal lipid metabolism, low hemoglobin and high blood glucose.

The present study was aimed to explore the changes of phosphorylated AMP-activated protein kinase (pAMPK) level in skeletal muscle after exposure to acute hypobaric hypoxia and exhaustive exercise. Thirty-two male Sprague-Dawley (SD) rats were randomly divided into sea level and high altitude groups. The rats in high altitude group were submitted to simulated 5 000 m of high altitude in a hypobaric chamber for 24 h, and sea level group was maintained at normal conditions. All the rats were subjected to exhaustive swimming exercise. The exhaustion time was recorded. Before and after the exercise, blood lactate and glycogen content in skeletal muscle were determined; AMPK and pAMPK levels in skeletal muscle were detected by Western blot. The results showed that the exhaustion time was significantly decreased after exposure to high altitude. At the moment of exhaustion, high altitude group had lower blood lactate concentration and higher surplus glycogen content in gastrocnemius compared with sea level group. Exhaustive exercise significantly increased the pAMPK/AMPK ratio in rat skeletal muscles from both sea level and high altitude groups. However, high altitude group showed lower pAMPK/AMPK ratio after exhaustion compared to sea level group. These results suggest that, after exposure to acute hypobaric hypoxia, the decrement in exercise capacity may not be due to running out of glycogen, accumulation of lactate or disturbance in energy status in skeletal muscle.

AIMTo investigate the transforming growth factor beta1 (TGF-beta1) and basic fibroblast growth factor (bFGF) expressions in benign prostatic hyperplasia (BPH) and the effect of beta-radiation.

METHODSTGF-beta1 and bFGF expression was studied by means of an immunohistochemical method in nine normal prostatic (NP) tissues, 15 hyperplastic prostatic tissues and 35 hyperplastic prostatic tissues treated with 90Sr/90Y.

RESULTSThe TGF-beta1 expression in the epithelium and stroma of normal prostatic tissues was 68.2 % +/- 10.5 % and 29.7 % +/- 4.6 %, respectively, while it was 64.8 % +/- 9.3 % and 28.6 % +/- 4.1 %, respectively, in hyperplastic prostatic tissues. Compared with the controls, TGF-beta1 expression in the epithelia and stroma of BPH treated with 90Sr/90Y increased significantly (P <0.01). The bFGF expression in epithelia and stroma of normal prostatic tissues was 17.4 % +/- 3.7 % and 42.5 % +/- 6.8 %, respectively, and was 46.3 % +/- 8.2 % and 73.2 % +/- 12.1 %, respectively, in hyperplastic prostatic tissues. Compared with the controls, expressions of bFGF in the epithelia and stroma of BPH treated with a 90Sr/90Y prostatic hyperplasia applicator decreased significantly (P <0.01).

CONCLUSIONExposure of beta-rays had noticeable effects on BPH tissues, enhancing TGF-beta1 expression and inhibiting bFGF expression.
