Objective To investigate the concentration of blood uric acid and the prevalence of hyperuricemia in staff of a univer-sity so as to provide scientific basis for prevention and treatment of hyperuricemia.Methods Uric acid(UA)of 4 893 persons were detected by enzymatic method.For male whose UA>428 μmol/L,For female whose UA>357μmol/L were considered as hyperuri-cemia.People enrolled in the study were grouped according to age and analyzed.Results The average UA of males was (357.23± 75.17)μmol/L and was significantly higher than that of females(P <0.05).The average UA concentration and hyperuricemia rati-os in males of 20-<30,30-<40 years old groups were the highest,that of 60 -<70 group was the lowest,the difference was statistically significant(P <0.05).The average UA and hyperuricemia ratios of the male group decreased with age before 70 year old.But The average UA and hyperuricemia ratios of 70-<80 and ≥80 groups were higher than that of the 60-<70 group,the difference was statistically significant(P <0.05).The average UA and of hyperuricemia ratio of the female group increased with age.Conclusion The average UA concentration of males was significantly higher than that of female,in addition to that,hyperuri-cemia patients become younger and younger in male population.

Objective To compare the effects of 2 kinds of frequency of transcutaneous electrical nerve stimulation (TENS) on urinary incontinence after stroke. Methods 81 patients with post-stroke urinary incontinence were randomized into group A (n=27), group B (n=27) and group C (n=27), who accepted TENS (biphasic square waves with pulse durations of 150 μs) in 20 Hz, 75 Hz and medcine only, respectively, for 90 days. They were assessed with Overactive Bladder Symptom Scores (OABSS), Barthel Index (BI), and voiding diary before and after treatment. Results The OABSS, BI and voiding diary improved significantly after treatment (P<0.05) in groups A and B, and improved more in the group A than in the group B. There was not significant improvement in the group C (P>0.05). Conclusion TENS of 20 Hz is more effective to reduce the incontinence post stroke.

BACKGROUND:Low toxicity of Genipin has certain species and cellspecificity. Biocompatibility of Genipin cross-linked type I colagen with human adipose-derived stem cels is essential for construction of
tissue-engineered adipose.
OBJECTIVE:To investigate the bbiocompatibility of Genipin cross-linked type I colagen with human adipose-derived stem cels.
METHODS:Human adipose-derived stem cels were isolated and cultured to the third generation, and the cels were seeded on Genipin cross-linked type I colagen scaffold. MTT assay was used to evaluate the adhesion and proliferation of cels on the scaffold, and the toxic effects of Genipin cross-linked type I colagen on human
adipose-derived stem cels. Optical microscopy and scanning electron microscopy were utilized to observe the adhesion and growth process of human adipose-derived stem cels on the scaffold as wel as the morphological changes of cels.
RESULTS AND CONCLUSION:Human adipose-derived stem cels could adhere to the scaffold immediately
after seeded and increase gradualy on the scaffold, with the average adhesion rate of 86.5%. Optical microscopy and scanning electron microscopy showed that human adipose-derived stem cels adhered wel on the scaffold. The cels increased gradualy over time, and could migrate into the scaffold, and distribute evenly with the passage of time when observed with optical microscopy. The result showed Genipin possesses very low cytotoxicity to the cels, and the outstanding biocompatibility is found between the cels and scaffoldin vitro after cross-linked with Genipin.

BACKGROUND:Based on the original advantages of silk fibroin, positive charged water-soluble chitosan modified silk fibroin is modified on surface and could improve celladhesion on the scaffolds. OBJECTIVE:To verify the biocompatibility of chitosan-modified silk fibroin with human adipose-derived stem cells (hADSCs), and feasibility of constructing tissue engineered adipose in vitro. METHODS:The hADSCs at passage 3 were seeded on chitosan-modified silk fibroin at the concentration of 1×107/L, as the experiment group;at the same cellconcentration, hADSCs were seeded in 96-wel plates as the control group. MTT tests were performed to evaluate the adhesion, growth and proliferation of hADSCs on chitosan-modified silk fibroin. Then hADSCs were implanted on the chitosan-modified silk fibroin scaffolds at the concentration of 1×109/L. The hADSCs seeded onto chitosan-modified silk fibroin complexes were respectively cultured with adipogenic differentiation medium and ordinary high-glucose DMEM. The complexes were stained with oil red O, and detected with RT-PCR after cultured 14 days. RESULTS AND CONCLUSION:The hADSCs adhered to and proliferated on the scaffolds. After cultured with adipogenic differentiation medium for 14 days, oil red O staining demonstrated that there were amount of mature adipocytes on the scaffold. The peroxisome proliferator activated receptorγ2 was positively expressed. The chitosan-modified silk fibroin possessed excellent biocompatibility in vitro. The co-cultured hADSCs could be induced to mature adipocytes successful y.

OBJECTIVETo investigate the role of autophagy in acute lung injury (ALI) caused by multiple trauma in rats via pretreat with 3-methyladenine (3-MA).

METHODSForty-five Sprague-Dawley male rats, with age of 4 months and body weight of 250-300 g,were randomly divided into three groups. In the sham group, the rats received sphenotresia only;in the control group, the rats were made model of femur shaft fracture combined with brain injury, and treated with physiological saline by abdominal cavity at 1 hour before making model; in the 3-MA group, the rats were made model of femur shaft fracture combined with brain injury,and treated with 3-MA of 10 mg/kg by abdominal cavity at 1 hour before making model. Histologic changes and the concentration of related inflammatory factors in the damaged lung tissue were examined at 48 h after opteration, at the same time, the effect of 3-MA on the expression of LC-3 II and Beclin-1 was examined through reverse transcriptase polymerase chain reaction technique (RT-PCR).

RESULTSCompared with sham group, LC-3 II and Beclin-1 level in control group at 48 h after operation were obviously increased (P < 0.01). Compared with control group, LC-3 II and Beclin-1 level in 3-MA group at 48 h after operation were obviously decreased (P < 0.01). Compared with sham group, the level of proinflammatory cytokines (TNF-α and IL-6) in control group obviously enhanced (P < 0.01). Compared with control group, above items in 3-MA group was obviously lower (P < 0.01). Compared with control group,the histopathological damage of lung in 3-MA group obviously reduced (P < 0.01).

CONCLUSIONAutophagy can aggravate the acute lung injury caused by fracture of shaft of femur combined with brain injuries,but 3-MA can reduce tissue damage by inhibiting the autophagy and inflammatory response.
