Objective To evaluate the diagnostic and differential diagnotic values of DSA features for inflammatory pseudotumor of the liver(IPL). Methods An retrospectively comparative analysis of 12 hepatic inflammatory pseudotumors confirmed surgicopathologically from May 2002 to March 2007 with DSA features and correlative imaging data were carried out. Results 10 cases consisted of only 1 lesion and other 2 cases with multiple lesions were opacified initially at the late arterial phase,with prominent peripheral ring-like staining at portovenous and parenchymal phases and less dense opacification in the central region; furthermore heterogenous staining occurred in 5 cases. Conclusions DSA is probable the most appropriate method for the diagnosis and differential diagnosis of hepatic inflammatory pesudotumor.

BACKGROUND:The good rotational alignment of femoral prosthesis was very important in total knee arthroplasty. The research has shown that the posterior condylar angle was important to determine the alignment. The posterior condylar angle is the angle between the posterior condylar axis and the femoral epicondylar axis. MRI can clearly show the condylar cartilage, the projections of lateral epicondyle and the medial epicondyle depression, thus ensuring accuracy of measurement data. OBJECTIVE:To measure the posterior condylar angle of knee joint in the northern part of Baoding City in China, and to provide image evidence for identifying the rotational alignment of femoral prosthesis during total knee arthroplasty. METHODS:The knee was extended on a neutral position when MRI machine was applied to scan knee joint. The scanning plane was perpendicular to the mechanical axis of the knee. The best T1 axial plane of the knee was chosen, and two observers analyzed images independently. Existence rate of femoral medial epicondyle was observed using Bravo viewer 6.0 imaging software. The posterior condylar angle between posterior condylar axis and the femoral condyle axis was measured. RESULTS AND CONCLUSION:The posterior condylar angle was (2.73±1.28)° in males and (2.35±1.37)° in females on average, which did not show significant difference. The results showed that the MRI had great superiority in measuring the posterior condylar angle. The variability of the epicondylar axis was smal in total knee arthroplasty. Posterior condylar angle can be referenced to position femoral prosthesis and to avoid the complications after knee replacement.

Objectives To compare the co-infection statues of HSV, HBV and HCV in patients with STD and HIV infection for providing evidence of developing prevention and control strategies. Methods Serum samples confirmed to be infected with HIV/AIDS by Western blot, and serum samples of patients with STDs (syphilis, gonorrhoea and chlamydial infection) were tested for HSV2-IgG, HSV2-IgM, HBsAg and HCV-IgG by ELISA. The detection levels were compared between the two groups. Results Out of 76 specimens in STD group, HSV2-IgG was detected in 24 specimens (31.58%), HSV2-IgM in one specimen (1.32%), HBsAg positive in 8 (10.53%), and HCV antibody positive in 4 (1.32%). In 14 specimens of HIV/AIDS group, HSV2-IgG were detected in 7 (50.00%); HSV2-IgM in 5 (35.71%);8 (578.14%) were positive for HBsAg and 3 (21.43%) for HCV. In a total of 90 specimens, both HSV and HBV were detected in 6 specimens, both HSV-IgM and HBV in 2, and the four above-mentioned antibodies in 2. The infection rates of HSV, HBV and HCV were significantly higher in HIV-infected specimens than those in the STD specimens (P

OBJECTIVE: To investigate the significance and relationship between the expression of FOXC1 and clinicopathological features, and to explore its correlation with E-cadherin. METHOD: Immunohistochemical SP method was used to detected the expression of FOXC1 in nasopharyngeal carcinoma tissues and nasopharyngitis tissues. RESULT: (1) Immunoreaction to FOXC1 was mainly located in nucleus of nasopharyngeal carcinoma cells. The positive expression rate of FOXC1 in nasopharyngeal carcinoma tissues was 85.3% (81/95), which was significantly higher than that in nasopharyngitis tissues (59.4%) (P < 0.05). (2) The expression of FOXC1 was not related to patients' age and gender, clinical stage of cancer and lymph node metastasis (P > 0.05). (3) There was a correlation between the expression of FOXC1 and down-regulated expression of E-cadherin in nasopharyngeal carcinoma tissues (P < 0.05). CONCLUSION FOXC1 may play an important role in generation and progression of nasopharyngeal carcinoma, there may be a correlation between the expression of FOXC1 and down-regulated expression of E-cadherin, also FOXC1 may play an important role in the process of EMT in nasopharyngeal carcinoma by regulating E-cadherin.

Background:As postoperative intra-abdominal septic complications( IASCs)in Crohn’s disease( CD)are difficult to manage,it is of great importance to prevent this condition in CD patients after surgery. Till now,there are no large sample studies on risk factors for postoperative IASCs in CD in China. Aims:To determine the risk factors for postoperative IASCs in CD for guiding the formulation of preventive strategies. Methods:This retrospective study was based on a computerized database of CD patients who had undergone surgery for CD complications between 1999 and 2014 at Nanjing General Hospital of Nanjing Military Command,PLA. Patients were divided into IASCs group and non-IASCs group. Thirty potential variables were selected,and both univariate and multivariate( Logistic regression)analyses were performed to identify the risk factors for IASCs after surgery. Results:Seven hundred and sixteen operations were reviewed,and IASCs occurred in 41 cases(5. 7%). By univariate and multivariate analyses,IASCs were significantly associated with one stage anastomosis(OR=1. 656,95% CI:1261-3. 279),preoperative low albumin level( <30 g/L)(OR=1. 457,95% CI:1. 152-2. 368),preoperative high CRP level( >10 mg/L)(OR=8. 641,95% CI:3. 376-16. 364),preoperative steroids use ≥3 months(OR=3. 785,95% CI:1. 237-4. 671)and presence of intra-abdominal abscess or infection at the time of surgery(OR=1. 784,95% CI:1. 155-3. 826). However,enterostomy(OR =0. 125,95% CI:0. 062-0. 561)and preoperative enteral nutrition ≥ 1 month( OR =0. 147,95% CI:0. 078-0. 781 ) were found to be the independent protective factors. Conclusions:Malnutrition,active CD and preoperative long-term steroids use increase the risk of postoperative IASCs in CD. Patients with these risk factors should not receive immediate surgery. If surgery is inevitable, enterostomy instead of resection and anastomosis should be the first choice. Preoperative enteral nutrition is helpful for reducing the occurrence of IASCs after surgery.

Purpose To investigate the topological structure differences between the migraine patients group and the normal control group by using resting-state brain complex networks constructed based on graph theory. Materials and Methods Resting-state functional magnetic resonance imaging dataset were obtained from 22 migraine patients and 22 normal subjects. The functional complex networks of the two groups were constructed, and parameters including average clustering coefficient, characteristic path length, small worldness, assortativity, and betweenness of the two groups were respectively calculated. Results When compared with the parameters of normal control group, average clustering coefficient of migraine patients group was larger, small worldness and assortativity were also changed. The characteristic path length of the caudate nucleus and putamen areas presented abnormal in the migraine patients group. Betweenness centrality of the thalamus, inferior occipital gyrus and occipital gyrus increased in the migraine patients group. Conclusion The abnormal brain regions in the migraine patients group were mainly associated with pain processing, visual processing and sensory information relay. This study may contribute to better understanding and interpreting corresponding clinical condition of migraine.

Nutrition therapy is an important part of the treatment of Crohn’s disease(CD),which plays an important role in correcting malnutrition,inducing disease remission,and for the perioperative management. Nutrition therapy, especially enteral nutrition(EN),has been studied for its effect on CD. We have long been focusing on the use of nutrition therapy in the treatment of CD,especially the use of EN in the perioperative management of CD. Here,we reviewed the indications,effects,endpoints and the underlying mechanisms of preoperative nutrition therapy,through which we hope can shed light on improving the optimization of preoperative management as well as the standardization of preoperative nutrition therapy in CD.

Objective To study the susceptibility of Neisseria gonorrhoeae to antibiotic agents from 1988 to 2002 in Shanghai. Methods The clinical isolates from patients with gonorrhea were collected and tested for their susceptibility to five antibiotics. Agarose-dilution-method was used to detect minimal inhibitory concentration (MIC) of anti-microbial agents including penicillin, tetracycline, spectinomycin, ciprofloxacin and ceftriaxone, and penicillinase producing Neisseria gonorrhoeae (PPNG) were tested with acidometric method. Results Susceptible strains to penicillin decreased from 11.28% in 1988 to 0 in 2002, MIC50 and MIC90 increased 8 and 4 times, respectively, the resistant rate and proportion of PPNG were 94.29% and 50.95%, respectively in 2002. The strains of high resistance to tetracycline increased from 0 in 1995 to 20.95% in 2002. The susceptible strains to ceftriaxone decreased from 100% in 1995 to 23.80% in 2002. The susceptibility to ciprofloxacin decreased significantly and resistant rate reached 99.05% in 2002. However, these strains were kept highly susceptible to spectionmycin. Concerning the multi-drug resistance, we found that the strains resistant to penicillin, ciprofloxacin and tetracycline simultaneously increased from 20.87% in 2001 to 23.30% in 2002, those resistant to both penicillin and ciprofloxacin reached to 70% in the past 2 years. Conclusions In Shanghai the resistant rates of Neisseria gonorrhoeae to antibiotics increased year by year in the past 15 years. The study indicates that spectinomycin and ceftriaxone should be the first choice for the treatment of gonorrhea at present and new sensitive antibiotic should be developed for the treatment of gonorrhea.
