BACKGROUND:Knowledge of retropedtoneal space communications might influence catheter placement,and understanding the normal anatomy of the retroperitoneal space is a prerequisite for predicting the distribution of inflammation or other fluid collections in this region. Until recent years,the media/ attachment of the posterior renal fascia remained controversial. The multiple detector spiral CT can show the abdominal anatomic details. So,using the multiple-detector spiral CT to study the anatomy of posterior renal fascia has clinical significance. OBJECTIVE:To describe the medial attachment of the posterior renal fascia by using multiple-detector spiral CT. DESIGN,TIME AND SETTING:A retrospective case analysis was performed at Department of Radiology,Affiliated Hospital of Weifang Medical College between June 2003 and November 2007. PARTICIPANTS:A total of 52 patients with retropedtoneal inflammatory diseases were retrospectively reviewed through analysis of their CT data. METHODS:Toshiba Akuilion 16-detector spiral CT was employed for scanning. Of the 52 patients,15 were proved by clinical and laboratory findings and 37 were proved by surgery and pathology. Among the 52 patients,17 suffered from appendicitis,1 from ureteritis,2 from abscesses in the perirenal space,3 from abscesses in the posterior pararenal space,and 29 from pancreatltis. MAIN OUTCOME MEASURES:Medial attachment of the bilateral posterior renal fascia. RESULTS:At the level of the upper pole of kidney,the posterior renal fascia fused with the fascia of the ipsilateral quadratus lumborum muscle. Forty-six patients manifested the attachment site of the left posterior renal fascia transforming from the quadratus lumborum muscle fasciae to the psoas major muscle fascia at the level of the lower pole of kidney or the infrarenal space. Fifty patients showed the attachment site of the right posterior renal fascia transforming from the quadratus lumborum muscle fascia to the psoas major muscle fascia at the level of the lower pole of kidney or the infrarenal space. CONCLUSION:The posterior renal fascia attachment site is not the same all the time. At different levels,the attachment site of the posterior renal fascia is distinct.

Objective To understand the status of Toxoplasma gondii(TOX)infection in pregnant women in Qingdao area. Methods Antibody capture ELISA was used to detect the TOX-IgM,IgG and TOX-DNA in 1 341 pregnant women and 201 infer-tility,miscarriage,stillbirth pregnant women from June 2011 to July 2013. Results Among 201 abnormal pregnant women,43 cases were TOX antibody positive,accounting for 22.39%,and among the normal pregnant women,84 cases were TOX antibody positive,accounting for 6.26%,and there was a significant difference(χ2 =10.60,P<0.05). The TOX positive rate of 20-29 years old women was higher than that of the women aged over 30 years(χ2=21.9,P<0.05). The TOX antibody positive rates of families with pets and families without pets were 26.63%and 8.77%respectively(χ2=10.93,P<0.05). The TOX antibody posi-tive rates were 10.94%(22/201)in unemployed women,3.98%(8/201)in farmers,3.98%(8/201)in staff,and 3.48%(7/201)in workers. Conclusions The TOX infection rate in abnormal pregnant women is significantly higher than that in normal pregnancy women;therefore,the health education should be strengthened. In addition,in young women,especially 20-29 years old women, and some special occupation women,the control measures should be enhanced.

Objective:To investigate the effect of metformin and arsenic trioxide on KG1a cells proliferation of acute myeloid leukemia and its possible mechanism.Methods:CCK-8 method was used to detect the killing effect of metformin,arsenic trioxide and combined application on KG1a cells.Annexin V-FITC/P1 Dual Stain Flow Cytometry was used to detect the effect of combined application on apoptosis of KG1 a cells.Western blot was used to detect the expression of intracellular apoptosis-,autophagy-related protein.Results:Metformin and arsenic trioxide alone or in combination could inhibit the proliferation of KG1 a cells and induce apoptosis of KG1 a cells,and the proliferation inhibition rate and apoptosis rate in the combined drug group were higher than those in the drug group alone(P＜0.05).The combination of drugs induced upregulation of Caspase 8 protein and P62 protein expression and was higher than that in the drug group alone(P＜0.05).Conclusion:Metformin can synergize with arsenic trioxide to kill KG1a cells,and its mechanism of action may be related to inducing apoptosis and enhancing autophagy.

Objective To investigate the type 2 diabetes mellitus(T2DM)prevalence and related risk factors in adult population with obesity in Tianjin. Methods With stratified cluster randomized sampling, 2888 obese people with BMI≥28 kg/m2, aged 18 years old and over were selected from three urban and three rural regions of Tianjin, in 2006. Information on risk factors was collected with questionnaire through face-to-face interview by trained workers and data on fasting blood glucose(FBG)was collected at the same time. 2hrPPG was tested among the people who' s FBG ≥6.1 mmol/L at the hospital. Prevalence of T2DM was calculated and the distribution of T2DM in the described subgroups and the risk factors analyzed with SPSS software. Results The prevalence of T2DM in adult population with obesity was 11.74%, with females(13.90%)higher than males (8.75%). The prevalence rates of T2DM were statistically different among different groups, classified by age, education, occupation, district and BMI. Results from the univariate and multivariate logistic regression analysis showed that the risk factors of T2DM were age(OR=1.383, 95% CI: 1.254-1 .525)and sex(OR= 1.591,95% CI: 1.230-2.059)while the protective factor was fruit intake(OR=0.867, 95% CI: 0.774-0.971). Conclusion The prevalence of T2DM in adult with obesity was considered to be high. The distribution of T2DM in different subgroups and affecting factors of T2DM in obese adults were different from general population.

Objective: To genotypically characterize methicillin-resistant Staphylococcus aureus (MRSA) strains isolated from medical and surgical wards in Universiti Kebangsaan Malaysia Medical Centre (UKMMC) in 2009. Methods: MRSA strains were collected and molecularly typed by pulsed-field gel electrophoresis (PFGE). Results:PFGE typing on 180 MRSA isolated in UKMMC identified 5 pulsotypes (A-E) and 6 singletons, where pulsotypes B and C were suspected to be divergent clones originating from a single ancestor. This study also showed that most MRSA strains were isolated from swab (119 isolates), followed by blood (22 isolates), tracheal aspirate (11 isolates) and sputum (10 isolates). On the other hand, urine and bone isolates were less, which were 4 and 1 isolates, respectively. The distribution of different pulsotypes of MRSA among wards suggested that MRSA was communicated in surgical and medical wards in UKMMC, with pulsotype B MRSA as the dominant strain. Besides, it was found that most deceased patients were infected by pulsotype B MRSA, however, no particular pulsotype could be associated with patient age, underlying disease, or ward of admittance. Conclusions: Five pulsotypes of MRSA and 6 singletons were identified, with pulsotype B MRSA as the endemic strains circulating in these wards, which is useful in establishment of preventive measures against MRSA transmission.

Objective To develop a real-time polymerase chain reaction(PCR)system to determine transcriptional level of MexAB-OprM multidrug efflux pump gene and to investigate the impact of androgra- pholide on MexAB-OprM gene transcription in Pseudomonas aeruginosa.Methods The fragments of mexB gene of mexAB-oprM operon and 30S rRNA gene rpsL were amplified and cloned into two plas- mids respectively.These plasmids were used as external standards for real-time PCR.Real-time PCR was applied to measure the mRNA transcripition of mexB and rpsL gene in Pseudomonas aeruginosa growing in medium with different concentrations of andrographolide.Results The plasmids for standard curve were constructed successfully.The relative mexB mRNA expressions in 50,100,150 and 200?g/mL andrographolide were 0.04?0.03,0.06?0.07,0.09?0.03 and 0.04?0.03 respectively, which were significantly lower than that in the control(0.24?0.04,P0.05).Conclusion Andrographolide can reduce the transcriptional level of MexAB-OprM,which may he one mechanism for its anti-infection effect.
