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.

In this study, efforts were made to collect 88 traditional Chinese medicine (TCM) prescriptions for treating ADHD from public literatures, establish a medication database and conduct data mining on the efficacy, properties, tastes, meridian entries and compatibility regularity of TCMs by using frequency analysis, association rules analysis and cluster analysis. The results showed 33 herbs with a high frequency (≥ 10%). The top 12 frequently applied ADHD herbs were respectively Acori Tatarinowii Rhizome, Polygalae Radix, Prepared Rehmanniae Radix, Os Draconis, Glycyrrhizae Radix et Rhizome, Poria, Concha Ostreae, Testudinis Carapacis et Plastri, Paeoniae Alba Radix, Schisandrae Fructus Chinensis, Fructus Corni, Dioscoreae Rhizoma. The top seven types of frequently applied ADHD herbs by effect were respectively tonic herb, sedative herbs, livei-wind calming herbs, heat clearing herbs, astringent herbs, awaking herbs and damp clearing and diuresis promoting herbs. The top three properties were warm, cold and neutral, with warm as the dominance. The top three tastes were sweetness, bitterness and acridity, with sweetness as the dominance. The top three meridian entries were liver meridian, heart meridian and kidney meridian. The association rules analysis showed commonly used herbal pairs. Polygalae Radix-Acori Tatarinowii Rhizome, Concha Ostreae-Os Draconis, Prepared Rehmanniae Radix-Fructus Corni-Os Draconis. Eight highly frequent cluster prescriptions were summarized based on the cluster analysis. This study indicates that basic TCM prescriptions for treating ADHD were principally composed of tonics (nourishing liver and kidney, invigorating heart and spleen) and tranquilization, which were supplemented with herbs for calming liver, clearing heat, promoting qi-circulation, promoting blood-circulation, reducing phlegm and calming endogenous wind. The combination of multiple data mining techniques can reflect the clinical medication regularity of herbs for treating ADHD in an overall and objective manner.

Objective To investigate the role of polymerase chain reaction (PCR) and fluorescence in situ hybridization (FISH) in diagnosis and differential diagnosis of primary lymphoma and lymphoma-like lesion of the uterine cervix. Methods Three cases of primary cervical diffuse large B-cell lymphoma (DLBCL) and two cases of cervical lymphoma-like lesion were retrospectively studied by detecting their PCRIgH rearrangement and chromosomal break of IgH, bcl-6, bcl-2 and mye genes with FISH. Results PCRIgH gene rearrangement analysis demonstrated that the monoclonal rearrangement of IgH gene was occurred in 3 cases of cervical lymphoma and 1 case of lymphoma-like lesion, Interphase FISH analysis detected IgH gene break and bcl-6 gene break in all the three cases of cervical lymphoma, while no specific chromosomal break of IgH, and bel-6, bcl-2 and myc genes was detected in two cases of cervical lymphoma-like lesion.Conclusion PCR-IgH gene rearrangement is not specific to cervical B-cell lymphoma. Analysis of IgH gene break and bcl-6 gene break with interphase FISH is helpful to differential diagnosis between B-cell lymphoma and lymphoma-like lesion of the uterine cervix.
