Objective To analyze the effect of serum creatinine, blood urea and renal function with angiography low permeability of non-ionic contrast agent in elderly patients with ischemic cerebrovascular disease,and provide reference for clinical treatment.Methods 100 elderly patients with ischemic cerebrovascular disease in hospital from April 2011 to May 2016 were selected,patient were given cerebrovascular, renal arteriography.The changes of serum creatinine and urea were detected at different time before and after 3 days, and the changes of renal function were detected.Results In 100 cases, 12 cases of contrast induced nephropathy, the incidence rate was 12%.Contrast nephropathy in patients with diabetes mellitus group proportion, renal insufficiency, the proportion of severe renal artery stenosis was significantly higher than the proportion of non contrast nephropathy group (P<0.05).Contrast nephropathy group contrast 1 days and contrast 2 days blood urea, serum creatinine and creatinine clearance rate were significantly increased (P<0.05), contrast to 6 days gradually returned to normal, no obvious change of non contrast nephropathy in patients with renal function index.Diabetes mellitus (OR=6.973), severe renal artery stenosis (OR=4.286) and renal insufficiency (OR=7.680) are the risk factors of contrast induced nephropathy (P<0.05).Conclusion Vascular elderly patients with ischemic cerebrovascular disease using non-ionic contrast medium hypotonic angiography safer, diabetes, renal patients need to continue to pay attention to changes in renal function.

Objective To study the kinetic expression level of chemokines (RANTESF) in the murine infection of vulvovaginal can-didiasis (VVC), and explore the function of chemokines in local immunity of VVC. Method Sixty-three female Kunming mice, at 8 ～ 10 weeks of age, were used in this study. All animals were divided into three groups. The content variation of RANTESF in blood and yaginal fluids and CFU of vaginal fluid in each separate group of mice were detected at days 2, 7, and 14 after infection. The first group was control group. The second group was infected only one time and the third group was infected twice. The results were analyzed with SPSS 13.0 statis-tical software. Results The content variation of RANTESF and CFU in vaginal fluid reached highest at days 7 in both the first and the sec-ond groups, as well as in the blood. There were no notable changes at days 2 and 14. The content variation in vaginal fluid or blood of the second group was higher than that in the first group after infection. Conclusion CMI, as a host defense mechanism, plays an important role in protecting against vulvovaginal candidiasis, especially in secondary infection. Local innate immunity is more important than systemic in-nate immunity for protection against vulvovaginal candidiasis. Cytokine about RANTES can promote innate immunity modulation; especially the local innate immunity modulation can promote the ehemotaxis of RANTES.

Objective To understand the genotype distribution of Mycobacterium tuberculosis and the drug susceptibility of M.tuberculosis with different genotypes in Changping district of Beijing and evaluate the application of genotyping of M.tuberculosis in local tuberculosis (TB) prevention and control.Methods A total of 1 099 M.tuberculosis strains isolated in Changping from 2011 to 2015 were used.Spoligotyping and 12-locus VNTR recommended by Gao were used for the genotyping of these isolates.In addition,the susceptibility of the M.tuberculosis isolates to rifampin (RFP),isoniazid (INH),ethambutol (EMB),streptomycin (SM),amikacin (AMK) and ofloxcin (OFX) were detected by using conventional drug susceptibility test.Results From 2011 to 2015,the detection rate of OFX-resistance increased from 2.9％ to 8.9％ (P=0.01).Of all the M.tuberculosis isolatcs,976 belonged to Beijing genotype (88.8％),and the other 123 belonged to non-Beijing genotype (11.2％).In addition,there were 189 ancient Beijing genotype isolates and 787 modern Beijing genotype isolates,respectively.The proportion of Beijing genotype strains showed no significant increase in the past five years (81.1％ in 2011 vs.82.0％ in 2015).On the basis of VTNR genotyping,only 2 isolates belonged to one cluster (0.1％).In addition,the AMK resistant rate of Beijing genotype strains (1.7％)was significantly lower than that of non-Beijing genotype strains (4.9％,P=0.02).Compared with modern Beijing genotype strains,the SM resistant rate of ancient Beijing genotype strains was significantly higher (28.0％ vs.15.7％,P=0.01).Conclusions In the past five years,the OFX-resistant rate of M.tuberculosis in Changping was in increase.There was no significant difference in the detection of Beijing genotype strains during this period.In addition,the low clustering rate indicated that the TB transmission rate was low in Changping.

Objective To explore the influence of extubation time of urinary catheter on post-operational urination and comfort degree of patients with orthopedic surgery, so as to and make clear the best extubation time of urinary catheter for them. Methods 900 patients treated with operation in Department of Orthopaedics in the Third Hospital of Hebei Medical University from April to June in 2016 were selected by convenience sampling and divided, according to extubation time of urinary catheter, into group A, B and C, each with 300 cases. For patients in group A, urinary catheters were removed in the morning the day after the operation(12~24 h after operation), while in group B, 6 h after, and in group C, 2 h after. Rate of successful urination after extubation of urinary catheter, bladder discomfort, incidence rate of acute urinary retention and comfort degree of indwelling catheter in the three groups were compared. Results Difference in rate of successful urination and incidence rate of frequent micturition, urgent urination, micturition pain and acute urinary retention of patients in the three groups showed statistic significance (P<0.05). It was shown in pairwise comparison that rates of successful urination in group A and B were higher than that in group C, while incidence rates of acute urinary retention were lower (P < 0.05), and that incidence rate of frequent micturition, urgent urination and micturition pain in group A was higher than that in group B and C (P<0.05). Difference in comfort degree of indwelling catheter in the three groups showed statistic significance (P < 0.05). Incidence rates of discomfort in degree Ⅱ in group B and C were less than that in group A, while incidence rate of discomfort in degree Ⅲ in group C was less than that in group A and B (P<0.05). Conclusions For orthopedic patients,the best extubation time of urinary catheter is 6 h after the operation, which helps to raise rate of successful urination, lower urethra irritative symptoms due to cathetering, and reduce bladder discomfort after extubation.
