OBJECTIVE To discuss the antibiotic resistance situation of Pseudomonas aeruginosa and provide basis for therapy and control of the nosocomical infection. METHODS Fourteen strains of P.aeruginosa which derived from 60 and more years aged patients in intensive care unit(ICU) were analyzed by conventional chemistry test,PCR inspection,antimicrobial susceptibility test,plasmid pattern analysis and enterobacterial repetitive intergenic consensus(ERIC)-PCR polymorphism analysis. RESULTS Fourteen strains had the same chemistry traits,many strains appeared multi-antibiotic resistance,10 strains had a plasmid of 23kb or so without obvious association with(multi-antibiotic) resistance,14 strains were divided into three clusters by ERIC-PCR technique and their banding pattern cluster analysis,their similarity coefficients were from 0.62 to 0.86. CONCLUSIONS Nosocomial infection of P.aeruginosa which screened from aged patients in ICU has taken on sporadic state;ERIC-PCR fingerprinting technique genotyping method has high discrimination,and good reproducibility and give faster genotyping result with less hands-on time,which serves as nosocomial infection epidemiologic surveillances of P.aeruginosa.

Objective To investigate the early diagnosis and treatment of pelvic fracture with vaginal injury.Methods From January 2000 to July 2010,13 patients suffered from pelvic fracture with vaginal injury were treated in our hospital,whose average age was 31.7 years.According to the Tile classification,there were 4 cases of type B1,1 case of type B2,4 cases of type B3,3 cases of type C1,and 1 case of type C2.Emergency repair of vagina together with open reduction and internal fixation of pelvic fracture was performed in 3 patients.After the patients' condition became stable,5 patients with shock were treated with emergency repair of vagina together with primary external fixation of pelvic fracture.Prompt repair of vagina together with open reduction and internal fixation or primary external fixation of pelvic fracture was performed in 2 patients who underwent delayed diagnosis.Two cases of extensive pelvic abscess due to missed diagnosis of vaginal laceration were treated with debridement and external fixation of pelvic fracture,and reconstructions of vagina were performed after infection control.Results Twelve patients survived,and 1 patient died 6 h after admission.Eleven patients were followed up for 8 to 36 months (average,17 months).Among 9 patients who underwent one-stage repair of vagina,5 married patients had normal sexual life,1 suffered from pain during sexual intercourse,and 3 unmarried patients had normal menses.Two patients who underwent second-stage reconstruction of vagina suffered from pain during sexual intercourse.At final follow-up,the mean Majeed score was 82.2 (range,56 to 96),and the results were excellent in 6 cases,good in 3 cases,fair in 2 cases.Conclusion Vaginal injury should be highly suspected in females with anterior pelvic ring fracture.Early diagnosis and repair of vaginal injury is crucial to good clinical outcomes.Delayed diagnosis and treatment may lead to severe complications.

BACKGROUND:During spinal degeneration process, the intervertebral disc and facet joints are interrelated and interacted to impact the normal function and stability of the spine, thereby resulting in low back pain. Moreover, there is always a controversy on the degeneration order of the intervertebral disc and facet joint. OBJECTIVE:To explore the relationship between lumbar facet joint degeneration and intervertebral disc degeneration in patients with low back pain. METHODS: A retrospective analysis was made on the clinical data of 186 patients with low back pain. The facet joint degeneration and intervertebral disc degeneration at L2-S1 motion segments of each patient were evaluated. Enroled patients were divided into three age groups: < 40 years old, 40-60 years old and≥ 60 years old. RESULTS AND CONCLUSION:The incidence of lumbar facet joint and intervertebral disc degeneration was increased with age, and degeneration of the lumbar facet joint and intervertebral disc were the most obvious at L4-5 and L5-S1 segments. The incidence of intervertebral disc degeneration was more than that of facet joint degeneration at each segment in al age groups, except groups of < 40 years old and 40-60 years old at L2-3 segments, but there was no significant difference (P > 0.05). There was a weak correlation between facet joint degeneration and intervertebral disc degeneration (χ2=100.9,P < 0.001, gamma=0.22). These findings show that the incidence of intervertebral disc degeneration and facet joint degeneration is increased with age, and there is a weak correlation between them. However, the lumbar degenerative order is stil unclear and further research is needed.

Objective To explore the liver toxicities of the VDLD scheme in children with malignant tumor.Methods In a prospective trial,the levels of serum total protein,albumin, globulin,rate of albumin/globuin alanine aminotransferase,aspartate transaminase,gamma glutamyltranspeptidase,total bile acid and alkaline phosphatase were tested in children with malignant tumour before and after VDLD scheme,and compared with each other.Results The concentration of the serum total bile acid was significantly increased after VDLD scheme than before(P

Objective To investigate the role of Huang-qi in balance of TH1/TH2 in asthma on dendritic cells level. Methods DCs from human peripheral blood mononuclear cells(PBMC) were induced by rhGM-CSF and rhIL-4, and then were identified. The level of IL-12 and IL-10 produced by DCs were de-tected by ELISA assay. After autoreactive T cells, mRNA of T-bet and GATA-3 was measured by RT-PCR. Simultaneously, IL-4 and IFN-γ were determined by flow cytometer. Results After 7 days culture, IL-12 was significantly decreased in asthma group compared to control group (P ＜ 0.01), whereas IL-10 on the opposite. At the 7th day of co-culture with T cells derived from floating cells, the IFN-γ/and T-bet mRNA level in asthma group were significantly decreased than that in control group, whereas IL-4, GATA-3 mRNA level, the ratio of IL-4/IFN-γ and GATA-3/T-bet were apparently increased in asthma group than that in control group(P＜0.01). After Huang-qi treatment, the IFN-γ/and T-bet mRNA level were significantly in-creased, whereas the ratio of IL-4/IFN-γ and GATA-3/T-bet, and the IL-10 level were apparently de-creased, but the level of IL-12, IL-4 and GATA-3 mRNA were not changed significantly. Conclusion DCs in asthma regulated the balance of TH1/TH2 by means of secreting decreased IL-12 and increased IL-10, that made TH2 playing a dominance role which is the key factor in initiating asthma. Huang-qi regulated DCs through decreasing the level of IL-10, and thus decreased the ability of inhibiting the differentiation of TH1 from TH0, that is also inhibiting the differentiation of TH2 from TH0 directly.

ObjectiveTo investigate fecal diversion in the management of pelvic fractures associated with perineal injuries.MethodsThis retrospective study involved 27 patients of pelvic fractures associated with perineal injuries during April 2005 to April 2011.There were 23 males and 4 females,and the mean age was 32.9 years old (range,16-62 years old).Fractures type according to Tile classification:4 cases were type A,10 cases were type B,and 13 cases were type C.The pelvic external fixator and fecal diversion were selectively used.Results Of the 27 patients of pelvic fractures associated with perineal injuries,24survived.The overall mortality of pelvic fractures associated with perineal injuries in the present study was 11％.The survived 24 patients were totally reviewed clinically.The mean follow-up time of these patients was 10.9 months (range,4-42 months).Of those patients who underwent early fecal diversion (＜ 48 h),none experienced infectious completions.However,of those underwent non-early (＞48 h) fecal diversion (including those who did not undergo fecal diversion),four patients experienced infectious completions.Fisher's exact test was used to compare the infection rate of these two groups.And the result of Fisher's exact test demonstrated that those patients who underwent early (＜ 48 h) fecal diversion and non-early (＞48 h) fecal diversion (including those who did not undergo fecal diversion).ConclusionStabilization of hemodynamic; selective fecal diversion; early stabilization of pelvic fracture are necessary for the emergency management of pelvic fractures associated with perineal injuries.Rectal injury and severe perineal injury without involvement of rectum should undergo fecal diversion.Early fecal diversion (＜ 48 h) could reduce the infection rate of pelvic fractures associated with perineal injuries.

Objective To study the effect of serum uric acid (UA) levels on kidney graft function as well as long-term graft survival after renal transplantation.Methods The clinical data of 859 kidney transplant recipients from Jan.2008 to May 2014 were investigated retrospectively.The differences in clinical indexes between normal UA group and hyperuricemia group were compared based on UA levels.Cox regression model was built to analyze the effect of elevated UA on overall graft loss,death censored graft failure and death of patients,respectively.Kaplan-Meier graft survival curve was used to compare the overall graft loss,death censored graft failure and death of patients between normal UA group and hyperuricemia group.Results The average follow-up time was 38.6 ± 17.3 months for 859 kidney transplant recipients.590 (68.7％) recipients were enrolled in normal UA group and 269 (31.3％) recipients were defined as hyperuricemia patients.The average eGFR in hyperuricemia group was significantly decreased as compared with normal UA group (79.4 ± 20.93 vs.94.7 ± 20.55,P＜0.001).Cox regression model showed that if UA level increased per 10 mol/L,the risk of overall graft lost increased 1.070 times (P＜0.001) and the risk of death censored graft failure increased 1.121 times (P＜0.001) accordingly.Kaplan-Meier analysis showed the overall graft loss was dramatically decreased (P =0.009),and the death censored graft failure was significantly decreased (P＜0.0001) in hyperuricemia group as compared with that in normal UA group.The death of patients showed no significant difference between two groups (P =0.638).Conclusion Serum UA levels after kidney transplantation affect graft function as well as long-term graft survival.
