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.

This article described systematically the design basis,passing standard and influential factor of test score of the assessment scale of simulated clinical skills examination.Through developing and modifying OSCE examination scale design for many years,we have found that the use of 360-degree assessment for designing OSCE assessment rating scale can effectively reduce the impact on the score of examinee owing to the environment,the candidates,raters and question design,which has an important role for scientific development of OSCE assessment scales,as well as improving the reliability and validity for development of a scientific OSCE assessment.

ObjectiveTo screen the colonization of multidrug resistant organisms (MDROs) and determine their risk factors in intensive care unit (ICU), so as to provide the basis of prophylaxis and treatment of MDROs colonization.Methods A prospective single-center study was conducted in ICU of China-Japan Friendship Hospital from June 2008 to December 2014. The nostril and anal swabs for each patient who stayed in ICU over 24 hours were collected. Each specimen was cultured and tested for drug sensitivity. Clinical findings and relative risk factors were collected. The risk factors of MDROs colonization were analyzed with univariate analysis. The independent risk factor was selected from the risk factors withP< 0.05 with logistic regression analysis to analyze the related factors of MDROs colonization in ICU.Results 1 672 patients were enrolled. At ICU admission, MDROs colonization was present in 604 cases (36.12%), of whom 62 cases (3.71%) were found to be colonized with methicillin-resistantStaphylococcus aureus (MRSA), 529 (31.64%) were colonized with extended-spectrumβ-lactamase (ESBL) enterobacteria, 7 (0.42%) were colonized with multidrug resistantAcinetobacter baumannii (MDR-AB), and 6 (0.36%) were colonized with multidrug resistantPseudomonas aeruginosa (MDR-PA). ICU acquired MDROs colonization were 197/1 068 (18.45%), among whom 24 patients (1.44%) were colonized with MRSA, 118 (7.06%) were colonized with ESBL enterobacteria, 50 (2.99%) were colonized with MDR-AB, and 5 (0.30%) were colonized with MDR-PA. By multivariable analysis, prior administration of more than two kinds of antibiotics [odds ratio (OR) = 2.352, 95% confidence interval (95%CI)=1.847 - 4.464,P = 0.002], prior use of broad spectrum antibiotics within 3 months (OR = 2.862, 95%CI = 1.458-5.631,P = 0.014), duration of prior antibiotic administration (OR = 1.781, 95%CI = 1.152 - 3.413,P = 0.003) and hospitalization days prior to ICU admission> 9 days (OR = 1.766, 95%CI = 1.235 - 3.986,P = 0.021) were independent risk factors of MDROs colonization on admission to ICU.ConclusionsHigh prevalence of MDROs colonization in ICU patients was found in our hospital, and ESBL enterobacteria was the predominant bacteria. ICU acquired MDROs colonization is also worth considering, especially for MDR-AB. Identification of risk factors for MDROs colonization may help identify and screen patients with high risk, and it is also instructive in prophylaxis of MDROs colonization/infection and restriction of the use of broad spectrum antibiotics.

ObjectiveTo explore the relationships among atrial natriuretic peptide (ANP) and cerebral vasospasm (CVS) following subarachnoid hemorrhage (SAH) and hyponatremia.MethodsPlasma ANP levels and serum natrium and blood flow rate of intracal major arterial were assessed at different times (1 to 3 days, 7 days and 14 days after SAH) in 42 patients with SAH. Correlation analysis was carried out among plasma ANP, blood sodium level and blood flow rate of intracal major arterial.Results28 patients had CVS. Plasma ANP levels in CVS patients significantly elevated compared with non-CVS and control subjects (P<0.05). Hyponatremia in CVS patients also significantly elevated compared with non-CVS subjects (P<0.05). Plasma ANP level had significant negative relationship with serum natrium level at the 7th day and 14th day (r2=-0.778,r3=-0.653;P<0.01,P<0.05) in SAH patients. Plasma ANP level had significant positive correlation with middle cerebral artery mean flow velocity on the 7th day (r3=0.702,P<0.05) in SAH patients. Middle cerebral artery mean flow velocity had significant negative relationship with serum natrium level on the 7th day and 14th day (r2=-0.693,r3=-0.653 , both P<0.05) in SAH patients.ConclusionANP might cause hyponatremia following SAH and play an important role in pathogenesis of earlier period CVS.

Animal models with kidney disease are generally divided into two types. One belongs to the models which imitate human kidney disease by the artificial operations, such as anti-glomerular basement membrane antibody nephritis, Heymann nephritis, anti-Thyl. 1 antibody nephritis, BSA nephritis and puromycin nephropathy. The other one pertains to the models which make themselves kidney disease, and appear the pathological characteristics naturally as like as human, such as HIGA mice with IgA nephropathy and NZB/WF1 and MRL/1pr mice with lupus nephritis. In addition,the transgenic animal models with kidney disease can also be established by the modern molecular biologic techniques including gene knockout and siRNA transfection. As for the studies related with kidney disease in pharmacodynamics and pharmacology of Chinese herbal medicine (CHM), it is important to understand deeply the features of each animal model with kidney disease, and select accurately the proper models according to the different experimental objectives, and then, build the special models provided with the combination of disease with syndrome in traditional Chinese medicine (TCM). Therefore,it is the developmental direction for the further study to establish animal models with kidney disease, which should possess the characteristics of syndrome in TCM.

Methods FHIT protein and HER_2 expressions in 50 lung cancer cases and 21 adjacent non-cancer tissues were performed by immunohistochemistry. And the positive rates of FHIT and HER_2 were measured. Results The positive rates of FHIT protein were 30.00% in lung cancer tissues. The expression levels of FHIT were significantly lower in lung cancer tissues than that in non-cancer lung tissues (P

Objective To establish a method for amplification of immature dendritic cells(DC) from murine bone marrow in vitro and investigate correlations between maturation degree of DC and varying dosages of granulocyte-macrophage-colony stimulating factor(GM-CSF).Methods Dendritic cells from murine bone marrow were cultured with different dosages of rm GM-CSF.The suspension cells were examined with scanning electronic microscope,and the non-sensitized T lymphocyte proliferation was observed by mixed lymphocyte reaction.Results DC cultured in lower dosage of rmGM-CSF(GMlow DC) exhibited typical characteristics of DC,and had immature characteristics in cell phenotype and cell functions with high expression of CD11c and low expression of CD80,CD86 and MHC II on the surface of the cells.The ability of GmlowDC to stimulate the proliferation of non-sensitized T lymphocyte in vitro was weaker than that of GmhighDC.Conclusions The methods of immature DCs culturing establised by allthors was feasible.The dosage of rm GM-CSF has a direct relationship with the maturation degree of DC.

Objective To use functional magnetic resonance imaging (BOLD-fMRI) to observe the efficacy of low-frequency repetitive transcranial magnetic stimulation (rTMS) combined with speech training in treating those with lateral fissure aphasia.Methods Forty-eight persons with lateral fissure aphasia were divided randomly into a control group and a treatment group,each of 24.The treatment group was treated with repetitive transcranial magnetic stimulation combined with speech training,while the control group was given only speech training.Before the treatment and 2 weeks and 8 weeks after the treatment,BOLD-fMRI images were collected to observe any changes in the language areas of the brain activated.A Chinese aphasia examination (CRRCAE) was used to assess speech function before and after treatment for both groups.Results The average CRRCAE scores of the two groups were not significantly different right before the treatment and at the end of 2 weeks of treatment,but at the end of 8 weeks of treatment the average score of the treatment group was significantly better.The biggest improvement was among those with Broca's aphasia,followed by those with Wernicke aphasia and conduction aphasia.No such differences were observed in the control group.After the 8 weeks of treatment,the average CRRCAE score of the treatment group patients had improved significantly,but in the control group only those with Broca's aphasia had improved significantly.In the treatment group,after 2 weeks and 8 weeks of treatment the activated language areas of the right hemisphere were significantly smaller than before treatment and significantly smaller than the activated areas in the left hemisphere at the same time points.Conclusions Low-frequency,repetitive transcranial magnetic stimulation combined with speech therapy is an early intervention which may promote recovery from lateral fissure aphasia through restoring lingual function after stroke.
