Objective To analyze the risk factors and distribution of pathogenic bacteria of urinary tract infection (UTI) patients with spi-nal cord injury (SCI). Methods A total of 452 patients with SCI collected from December, 2015 to June, 2016 were retrospectively analyzed. Results 104 cases (23.1%) were diagnosed as UTI. 119 strains were identified, including 96 strains of Gram-negative bacteria (80.7%) and 22 strains of Gram-positive bacteria (19.3%). Female, invasive operation, depressed lower limb muscle strength, neurogenic bladder and pre-vention of antibacterial agents use were considered to be the main risk infection factors. The invasive operation included indwelling urethral catheterization, intermittent catheterization and other transurethral operation. The incidence rate of UTI in patients with SCI who also accept-ed indwelling catheter was 100.0%. Conclusion Gram-negative bacteria is the dominated pathogenic bacteria in SCI patients with UTI. It should be noticed the characteristics of pathogen, which both may have the high drug resistance rate and high separation rate, to select exact-ly antimicrobial agents to control the spread and drug resistance of pathogenic bacteria. In addition, patients with underlying diseases, inva-sive operation and lower strength should be monitored targeted.

Objective To observe the expression levels of IL-8,IL-4,TNF-α of neonatal mouse with systemic inflammatory response syndrome(SIRS) treated by different doses of dexamethasone.Methods A total of 50 neonatal mice were randomly divided into five groups:blank control group,saline control group and treatment group A,B,C.The saline control group and treatment groups were established into SIRS models,treatment group A:a single high-dose of dexamethasone (2 mg/kg),subcutaneous injection (SC) ; treatment group B:two doses of dexamethasone (1 mg/kg,q1 2 h,total 2 mg/kg,SC) ; treatment group C:four doses of dexamethasone (0.5 mg/kg,q 1 2 h,total 2 mg/kg,SC) ;saline control group:saline of the same volume (0.4 ml/kg,SC).All mice were detected IL-4,IL-8,TNF-α by ELISA 72 hours after animal models being completed.Results The levels of IL-4,IL-8,TNF-α in saline control group and treatment group A,B,C were higher than those in blank control group respectively (P ＜ 0.05,respectively).The levels of IL-4,IL-8,TNF-α in treatment group A,B,C were lower compared to those of saline control group respectively (P ＜ 0.05,respectively),levels of TNF-α,IL-8 in treatment group B and C were lower than those of treatment group A(P ＜ 0.05,respectively).There were no significant differences in the level of IL-4 among treatment group A,B,and C (P ＞ 0.05).Conclusion Dexamethasone could lower the expressions of pro-inflammatory cytokines IL-8,TNF-α and anti-inflammatory factor IL-8 of neonatal mouse with SIRS,and the effect of multiple low-doses of dexamethasone on SIRS is significantly better than a single high dose.

Objective To investigate the protective effects of midazolam on noise-induced hearing loss in guinea pigs by testing reactive oxygen species (ROS) level in the cochlea and plasma SOD and MDA. Methods Totally forty male pigmented guinea pigs were randomly divided into four groups: control (C) , midazolam (M), normal saline (S) and noise-induced deafened (D) groups, with ten guinea pigs in each. Groups M, S and D were exposed to a continuous noise (4kHz , octave band, 100dB SPL) 3h every day for 3 consecutive days. Group M was treated with midazolam, which was administered intramuscularly (0.1mg/kg) 24h before noise exposure, and immediately upon and during noise exposure. Group S was exposed to noise and treated with the same volume of normal saline intramuscularly, the time of injection was the same as that of Group M. Group C was not exposed to noise, but was treated with midazolam intramuscularly, the time of injection and the dosage were the same as those of Group M. Group S was exposed to noise and treated with normal saline intramuscularly ,the time of injection was same with that of Group M.Group D was exposed to noise only. All animals received auditory brainstem response (ABR) threshold recording before and immediately after noise exposure. Blood was collected when the guinea pigs were killed after the last ABR threshold recording, and serum SOD activity and MDA content were detected. Both the cochleae were removed and prepared for ROS assay. Results After noise exposure, ABR threshold shift (1.6±1.5) and ROS content [(291.10±2.30)u/mL] in Group M were significantly lower than those in Groups S and D [41.7±3.3, 44.3±3.9; (348.52±3.60)u/mL, (315.56±6.70)u/mL, P<0.05]. Serum SOD activity and MDA content were significantly increased in Group M, but the amplitude was less than that in Groups S and D.Conclusion Midazolam can prevent noise-induced hearing loss by reducing the increased ROS level in the cochlea after noise exposure.

Objective To observe the curative effect in patients with systemic lupus erythematosus(SLE) complicated by moderate or severe thrombocytopenia with a blood platelet count(BPC) of under 50 × 109/L and analyze its related factors. Methods We retrospectively analyzed the clinical data on 109 SLE patients with mod-erate or severe thrombocytopenia. Results Of the 109 patients,82(75.2%)had complete response(CR),15 (13.8%)had partial response(PR),and 12(11.0%)had no response(NR),respectively. As compared with the CR+PR group,the NR group had a higher incidence rate of decreased bone marrow megakaryocyte(P < 0.05). However,there were no significant differences between the two groups in SLEDAI scores,rates of positive PAIg and ACA,and levels of C3 and C4(P>0.05 for all comparisons). The total effectiveness rate did not differ signifi-cantly between MP pulse therapy and high-dose corticosteroid therapy. Conclusions A decrease in bone marrow megakaryocytes can be an adverse factorfor affecting the efficacy in patients with SLE complicated by moderate or severe thrombocytopenia.

Objective To explore the clinical value of cardiac magnetic resonance imaging (CMRI) in assessment of right ventricular function in patients with pulmonary arterial hypertension (PAH).Methods The PubMed/MEDLINE,Wanfang data,CNKI (from January 2001 to April 2015) were searched.The search terms were pulmonary arterial hypertension,right ventricular function,and cardiac magnetic resonance imaging.An inclusion criterion was the patients suffering from PAH,and the healthy volunteers were served as controls.The study was designed as randomized controlled trial.All the subjects investigated had received CMRI.The end of the trial included right ventricular end diastolic volume (RVEDV),right ventricular end systolic volume (RVESV) and right ventricular ejection fraction (RVEF).Meta analysis was conducted by RevMan 5.0 software provided by Cochrane Collaboration,and the publication bias was analyzed by the funnel plot analysis.Results Five papers involving 381 patients met the criteria.It was showed by Meta-analysis that compared with healthy control group,RVEDV was increase in PAH group [weighted mean difference (WMD) =33.96,95％ confidence interval (95％CI) =20.80-47.12,P ＜ 0.000 01],RVESV was increased (WMD =41.91,95％ CI =29.63-54.19,P ＜ 0.0O0 01),and RVEF was decrease (WMD =-20.09,95％CI =-22.65 to-17.52,P ＜ 0.000 01).Conclusion CMRI can be used to evaluate the right ventricular function of patients with PAH,and it has important significance in the evaluation of right ventricular function in patients with PAH.

Objective To investigate human pulpal response to mineral trioxide aggregate (MTA) and calcium hydroxide (CH) as pulp capping agents. Methods This study was conducted on 90 intact first and second premolars of human maxillary and mandibular teeth of 30 volunteers. The patients were randomly assigned into three groups with 10 in each group. Under local anesthesia, the teeth were exposed and capped either with MTA, or CH. After 30, 60, and 90 days, 10 teeth of each group were extracted and prepared for histologic ob-servation. The data were analyzed with Wilcoxon rank sum test and paired t-tests (α = 0.05). Results MTA had a higher success rate and resulted in less pulpal inflammatory response and more predictable hard dentin bridge formation than CH (P < 0.05). Conclusion MTA appears to be a suitable replacement for CH in direct pulp capping.

Objective To evaluate the multi-detector CT (MDCT) on pulmonary changes in post-operative adult receptor of liver transplantation complicated with acute respiratory distress syndrome (ARDS).Methods Nineteen adult patients admitted into Tianjin First Center Hospital from January to December 2016 to perform the first time liver transplantation were enrolled in this study. Before operation, the CT showed no significant abnormality in the patients' lungs, after operation MDCT was applied to observe the pulmonary changes of ARDS post-operative complication in the adult receiver of liver transplantation, and the pulmonary changes in different gender of patients were analyzed and compared.Results MDCT showed that after liver transplantation all the 19 patients (100%) had lung pathological changes, of whom 18 cases (94.7%) manifested 2 or more than 2 kinds of pulmonary changes, including consolidation shadows (12 cases, 63.2%), patchy shadows (2 cases, 10.5%), ground glass opacity (6 cases, 31.5%) and pleural effusion (18 cases, 94.7%). In the comparisons between male and female patients with post-operative ARDS after liver transplantation, there were no significant differences in the lung pathological changes shown in MDCT (allP > 0.05) statistically.Conclusion The application of MDCT has great potential value in the evaluation of the disease situation after liver transplantation, that might providehelp to the postoperative treatment.

Globozoospermia is a rare and serious teratozoospermia, which is one of the important causes contributing to human male infertility. The assisted reproductive technique remains the only means for such patients to produce offspring. However, the pathogenesis of globozoospermia is not yet clear. In recent years, related studies have shown that some genes are connected with the onset of globozoospermia. This paper outlines the progress in the studies of pathogenicity genes, aiming to contribute to the molecular diagnosis and mechanism investigation of the disease.
