Objective To investigate the clinical significance of PET-CT to diagnose breast cancer and the axiUary lymph nodes metastasis. Methods 40 patients with breast cancer performed PET-CT were enrolled in the research. Qualitation the primary tumor and accuracy of PET-CT were evaluated on pathological results and compared with axillary lymph nodes dissection. To analyzed the concordance of the size of primary tumor on pathological result with B-mode ultrasonic and PET-CT and the correlation with the SUV. Results The accuracy, sensitivity and specificity of PET-CT in identifying breast cancer were 95%, 94%, 100%. The accuracy, sensitivity and specificity of PET-CT based on the situation of the axillary lymph node dissection were 88.2% 89.2% 83.3%. A significant association was found between tumor weiweihong and PET-CT, furthermore it had not association with SUV. Conclusion The diagnosis of PET-CT in identifying breast cancer and the axillary lymph node metastasis basically conforms to pathology. It possesses high sensitivity and specificity especially in identifying the size of the primary lesion. It offers a beneficial method to determine the axillary lymph node dissection and reasonable therapeutic regimen.

Objective To report a case presented with atypical clinical and radiological appearance in the early stage and finally pathologically confirmed as chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids ( CLIPPERS) , aiming to improve the understanding of the disorder. Methods The clinical, imaging, laboratory and pathological features as well as treatment and prognosis of a pathologically confirmed CLIPPERS patient with repeated relapsing-remitting course and stepwise progression in nine years were retrospectively analyzed. Results There were five relapsing-remitting processes in total clinical course of nine years. The clinical and radiological appearance was atypical in the early stage. At the first attack, the patient presented with fever, headache, altered consciousness and epileptic seizure. In the following courses, the patient presented with ataxia, blurred vision and limb weakness. Brain MRI (2006-2009) showed multiple abnormal signals including supratentorial white matter, pons and cerebellum with patchy gadolinium enhancement. Treatment with steroids resulted in a favorable clinical and radiological improvement. The symptoms of this attack included limb weakness, blurred vision, dysdipsia and dysarthria. Physical examination showed cognitive dysfunction, multiple cranial nerves injuries and bilateral pyramidal signs. Brain MRI showed multiple abnormal signals involved pons and cerebellum predominantly as well as supratentorial white matter with punctate gadolinium enhancement peppering the pons and cerebellum. A characteristic predominantly T lymphocytic perivascular infiltration was seen on brain biopsy. Both the imaging and histological findings were consistent with the CLIPPERS features. High-dose steroids treatment was given and obvious clinical and radiological improvements were observed. After discharge, steroids were reduced slowly combined with the use of immunosuppressant to avoid relapse of the disorder. Conclusions There is heterogeneity in clinical manifestations of CLIPPERS with repeated relapsing-remitting course and imaging presentations are sometimes atypical in the early stage, which leads to the misdiagonsis and missed diagnosis. Distinctive pathology is the “gold standard” for definite diagnosis. The nosological position of CLIPPERS is still unclear. Repeated relapse-remitting leads to secondary cerebral atrophy and degeneration, with the risk of progressing to primary central nervous system lymphoma. Early and vigorous steroids treatment with continuing maintenance immunotherapy results in the decreased relapse and best long-term prognosis. The neurologist should strengthen the understanding of CLIPPERS for early correct diagnosis and treatment aiming to reduce the functional disability.

Objective To investigate the value of transvaginal color Doppler sonography (TVCDS) and magnetic resonance imaging (MRI) in diagnosis for myometrial invasion of eudometrial cancer before surgical operation, in comparison with pathological examinations. Methods TVCDS and MRI were undergone before surgical operation in 34 patients with endometrial cancer confirmed by biopsy to evaluate depth of its myometrial invasion, as compared to those with postoperative pathological examinations. Results Predictive accuracy for myometrial invasion by TVCDS was 85%, with sensitivity, specificity, positive predictive value and negative predictive value of 80%, 9/9, 100% and 9/14, respectively, and predictive accuracy by MRI was 68%, with sensitivity, specificity, positive predictive value and negative predictive value of 60%, 8/9, 15/16 and 8/18, respectively. Resistance index (RI) averaged 0.51 for flow signal to detect superfical myometrial invasion by color Doppler flow imaging (CDFI) and 0.43 for deep myometrial invasion. Conclusions TVCDS and MRI can be used before surgical operation to judge the depth of myometrial invasion for patients with endometrial cancer, particularly more suitable for its screening, which will be helpful to judge the depth of myometrial invasion incorporated with resistance index by color Doppler flow signal.

The protective effects of diallyl trisulfide on liver were examined in rats with sepsis. Sepsis was reproduced in rats by cecum ligation and puncture (CLP). Fifty-six male Wistar rats were randomly divided into sham-operated group (group S, n=8), sepsis model group (group C, n=24), diallyl trisulfide (DATS)-treated group (group D, n=24). Animals in groups C and D were further divided into three subgroups according to different observation time points, with 8 rats in each subgroup· Rats in group D and C were intravenously injected with normal saline or DATS respectively at a dose of 20 mg/kg after the establishment of sepsis model. Eight rats in groups C and D were sacrificed at 3, 6 and 24 h post-CLP and their livers were harvested for detection of interleukin (IL)-1 receptor associated kinase-4 (IRAK-4), nuclear factor-κB (NF-κB), c-fos, c-jun, malondialdehydethhe (MDA) and superoxide dismutase (SOD), tumor necrosis factor alpha (TNF-α) and for pathological examination. The results showed that the levels of serum IRAK-4, NF-κB and TNF-α in hepatic tissues were higher in group C than group S (control group) (P<0.05). After DATS treatment, the levels of IRAK-4 and NF-κB in the hepatic tissues and serum TNF-α in group D were lower than those in group C (P<0.05). The levels of c-fos and c-jun and MDA in the hepatic tissues were higher in group C than in group S (P<0.05). After DATS treatment, the levels of c-fos and c-jun and MDA in the hepatic tissues were significantly lower in group D than in group C (P<0.05). When compared with group S group, concentration of SOD in the hepatic tissues in group C was significantly lower (P<0.05). After DATS treatment, the concentration of SOD in the hepatic tissues was higher in group D than in group C (P<0.05). These findings suggested that treatment with DATS could ameliorate sepsis-induced liver injury in rats. The protective effect might be related to its ability to inhibit the signal pathway of IRAK-4 and NF-κB, thereby decreasing the production of oxygen free radicals and down-regulating the expression of c-fos and c-jun.
