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 investigate the clinical characteristics and prognosis of patients with different molecular subtypes of breast cancer.Methods A cohort of 716 breast cancer patients which had clear immunohistochemical detection were investiged.Their molecular subtypes were categorized as Luminal A,Luminal B,HER-2 over-expressing and basal-like subtypes,based on detection of ER,PR,HER-2 expression,and the clinical data including characteristics,relapse,prognosis and prognostic factors of the patients with different subtypes of breast cancer were analyzed retrospectively.Results There were no significant differences among different molecular subtypes at the age,menopausal status,production times,clinical stage,and radiation therapy(P ＞0.05).There were significant differences among different molecular subtypes at axillary lymph node starus (x2 =17.208,P =0.001),turner size (x2 =20.528,P =0.000) and operation method (x2 =24.242,P =0.000) and chemotherapy regimens (x2 =10.711,P =0.013).Univariate and multivariate analyses showed that clinical stage (x2 =17.005,P =0.002),axillary lymph node status (x2 =11.267,P =0.000) and molecular typing(x2 =125.634,P =0.000) were independent prognostic factors affecting long-term survisal rate.Conclusion Breast cancer patients in different subtypes have different long-term survival rate.The patients in basal-like subtype have the worst long-term survival rate.Molecular subtypes may provide important information to predict the prognosis of breast cancer.

Objective:To analyze bone strength index, osteoporosis and fracture in ankylosing spondylitis (AS) patients with radiologic hip involvement and explore the characteristics of bone strength in these patients.Methods:According to bath ankylosing spondylitis radiology hip index (BASRI-hip) score, 339 AS patients were divided into two groups. The differences of bone strength in each group were analyzed by t-test, Mann-Whitney U test and χ2 test. Logistic regression was used to analyze the risk factors of bone strength index. The correlation between quantitative ultrasound and dualenergy X-ray absorptiometry (DXA) (total hip, g/cm 2) was analyzed. Pearson correlation analysis was used. Results:①Bone strength index of quantitative ultrasound was positively correlated with bone mineral density of DXA (total hip, g/cm 2), r=0.553, P<0.01. ② The age of 27(23, 37) years old in radiographic hip involvement was lower than 37(28, 48) years old in non-radiographic hip involvement, and the difference was statistically significant ( Z=-5.986, P<0.01). There were no differences in gender and course of disease between the two groups ( P>0.05).③ The radiographic hip involvement in AS patients whose ages were younger than 50, when compared with non-radiographic hip involvement patients, the bone strength index was lower (78±18 vs 84±16), while bone strength was lower than patients at the same age (41.0% vs 18.4%), however, the incidences of osteoporosis (42.7% vs 28.8%) and fragility fracture (3.7% vs 0%) were significantly higher ( t=3.028, P<0.01; χ2=16.758, P<0.01; χ2=5.886, P=0.019; χ2=4.67, P=0.038). For AS patients whose ages were ≥50, there were no significant differences between the two groups ( P>0.05). ④ Multivariate analysis showed that radiographic hip involvement [ OR (95% CI)=1.912(1.05, 3.48)], age [ OR (95% CI)=0.94(0.911, 0.97)] and body mass index (BMI) (kg/m 2) [ OR (95% CI) =0.875(0.807, 0.948)] were associated with lower bone strength. Conclusion:There is positive correlation between the bone strength index of quantitative ultrasound and bone mineral density of DXA. AS patients with radiographic hip involvement are characterized by decreased bone strength and are more likely to develop osteoporosis and fragile fractures. The risk factors of low bone strength are radiographic hip involvement, age and BMI.

The Qinghai⁃Tibet Plateau is known as one of the highest endemic areas of echinococcosis However，the dog infection rates of Echinococcus granulosus in the plateau regions were similar to other non⁃Tibetan areas with the high endemic，and most of the rates were below 40%. The infected dogs with E. multilocularis were ubiquitous in Ganzi Prefecture of Sichuan Province and Qinghai Province where many survey data were done and available，which was much different from those in non⁃Ti⁃betan areas where the geographical distribution of dogs infected with E. multilocularis was sporadic. The total infection rates of Echinococcus in dogs kept stable from 1983 to 2009 in Ganzi Prefecture of Sichuan Province and did not show much variation from 2000 to 2014 in Qinghai Province as well. Since 2006，the national comprehensive prevention and control strategy and mea⁃ sures against echinococcosis have been launched in China，and significant progress has been made. In the endemic Tibetan area of Sichuan，the general Echinococcus infection rates in dogs were 28.10%，15.87%，19.22%，3.28% and 1.11% from 2009 to 2013，respectively，and the Echinococcus coproantigen⁃positive rate in Gannan Prefecture of Gansu Province and parts of Qing⁃ hai Province also decreased. This paper reviews the literature on the characteristics of dog infections in the Qinghai⁃Tibetan Plateau，so as to provide useful information to support echinococcosis control and prevention there.

Objective: To investigate the dietary lead exposure level among children aged 3 to 4 years in Jiading District, Shanghai Municipality, and assess the health risk caused by lead exposure, so as to provide the basis for the management of children's food safety. Methods: Based on the 2023 Dietary and Health Status Surveillance Project in Jiading District, children aged 3 to 4 years from 12 streets (townships) in Jiading District were selected as the subjects using a multi-stage stratified random sampling method. The consumption frequency and daily intake of seven subcategories of four major food groups (beans, tofu), cereals (wheat, rice), meat (animal viscera), and aquatic products (mantis shrimps, bivalves) consumed by children over the past three months were collected using a food frequency questionnaire. Food samples were collected according to the food safety risk monitoring plan in Jiading District, and the lead content was detected. The health risks of dietary lead exposure among 3-4-year-old children were quantitatively assessed using the single-factor pollution index method, the Nemerow comprehensive pollution index method, and the margin of safety (MOS) method. Results: A total of 143 3-4-year-old children were surveyed, including 69 boys (48.25%) and 74 girls (51.75%). A total of 317 food samples were tested, and lead was detected in all seven subcategories of food samples, with an overall detection rate of 77.29%. The detection rates of lead in bivalves and mantis shrimps of aquatic products were relatively high (98.75% and 100.00%, respectively). The mean lead content of various foods ranged from 0.003 4 to 0.090 7, with the highest level found in bivalves. The lead content of all food samples did not exceed the standard. The single-factor pollution index of seven subcategories ranged from 0.017 2 to 0.148 0, and the Nemerow comprehensive pollution index ranged from 0.116 5 to 0.424 4, both of which were less than 0.7. The MOS (mean) ranged from 0.000 3 to 0.003 9, with an overall MOS (mean) of 0.012 2. The MOS (P95) ranged from 0.005 7 to 0.055 9, with an overall MOS (P95) of 0.112 4, both of which were less than 1. Conclusions The lead pollution level in the diet among children aged 3 to 4 years in Jiading District is safe and clean, with an acceptable impact on food safety. However, the detection rate of lead is relatively high, and the main source of dietary lead exposure is aquatic products.

OBJECTIVETo observe the effect of Shenshuaining Granule (SG) combined telmisartan on serum creatinine (SCr) levels and urinary albumin contents in diabetic nephropathy (DN) patients, and to explore its efficacy.

METHODSTotally 204 DN patients were recruited, and further assigned to 3 groups, i.e., the early DN group, the clinical stage of DN with normal renal function group, the clinical stage of DN with insufficient renal function group. Patients in the same group were randomly allocated to the telmisartan treatment group, the SG treatment group, and the combination of SG and telmisartan treatment group, 68 in each group. Patients in the telmisartan treatment group took telmisartan tablet, 80 mg per day, once daily. Those in the SG treatment group took SG, 5 g each time, 3 times per day. Those in the combination of SG and telmisartan treatment group took telmisartan tablet (80 mg per day, once daily) and SG (5 g each time, 3 times per day). The therapeutic course for all was 3 successive months. SCr levels, serum urea nitrogen (BUN),24 h urine microalbumin (24 h U-MA) were detected before and after treatment. Results In three different treatment groups, 24 h U-MA decreased after treatment in the telmisartan treatment group; SCr and BUN decreased after treatment in the SG treatment group; and 24 h U-MA, SCr and BUN decreased after treatment in the combination of SG and telmisartan treatment group (P<0.05). In the clinical stage of DN with insufficient renal function group, SCr obviously increased after treatment in the telmisartan treatment group (P <0. 05). In the 3 DN stages, SCr and 24 h U-MA obviously decreased in the combination of SG and telmisartan treatment group, when compared with the telmisartan treatment group and the SG treatment group (P<0.05). Compared with the telmisartan treatment group, SCr and BUN obviously decreased in the SG treatment group, but 24 h U-MA quantitation obviously increased (P<0.05). BUN obviously decreased in the combination of SG and telmisartan treatment group (P<0. 05).

CONCLUSIONThe combination of SG and telmisartan could decrease urinary albumin, and stabilize SCr levels.

Objective To explore the CT findings of mucoepidermoid carcinoma (MEC) of the tracheobronchial tree and improve the diagnostic accuracy. Methods The CT images, histopathological and clinical data in 24 patients with pathologically proved MEC of the tracheobroncbial tree were retrospectively analyzed. Results The clinical symptoms included cough, sputum, fever, wheezing, chest pain and hemoptysis. The patient was proved to be low-grade (n=19) and high-grade (n=5) MEC histopathologically. One lesion was located in trachea, 6 in main bronchus, 12 in lobar bronchus and 5 in segmental, subsegmental and distal bronchus. The tumor presented as no-invasive endotracheobronchial well-defined round-like nodule (n=13, locating in lobar and higher bronchus) and columnar sharp (n=3, locating in main bronchus), or intra-and-extraluminal well-defined round-like nodule or mass (n=6, locating in lobar and lower bronchus) and irregular mass with invasive pattern (n=2, high-grade type). The density of lesion was similar to the muscule and the calcification within lesion was showed in 4 patients on non-enhanced CT. The lesion had marked enhancement in 17 patients on enhanced CT. Obstructive changes were found in 20 patients. Conclusion MEC of the tracheobronchial tree is usually low-grade malignancy and locates in main and lobar bronchus with no-invasive well-defined airway mass, marked enhancement and calcification on CT.
