Objective To investigate the diagnostic value of low field MRI for adenomyosis. Methods MRI features of adenomyosis pathologically proved in 18 cases were retrospectively analysed.Results 15 cases were diffusive adenomyosis,the junctional zones of uterus were exteusive thickened to 12.0～32.6 mm,mean 16.2 mm,diffusive high signal intensity distributed over in myometrium which was low signal intensity in 11 cases,it was typical “snowing sign”,lower signal intensity in the myometrium in another 4 cases on T 2WI and fat-suppression imaging. A little high signal intensity was found in 6 cases on T 1WI. 3 cases were focal adenomyosis(adenomyoma), 4 lesions totally. The adenomyoma’s boundaries were not distinct and their shapes were roundish or irregular. The lesions were low signal intensity or diffusive high signal intensity distributed in the low signal intensity fields on T 2WI and fat-suppression imaging. A little high signal intensity was found in 2 lesions on T 1WI. Conclusion T 2WI and fat-suppression imaging of low field MRI are very useful techniques of the diagnosis of adenomyosis.

Purpose:To observe the response and tolerance to the regimen of etoposide,folinic acid and fluorouracil (ELF) in advanced gastric cancer. Methods:Thirty two patients with advanced gastric cancer received chemotherapy of ELF regimen(VP 16 100 mg iv d 1—3 ,CF 100—300 mg iv d 1—3,5 FU 750 1 000 mg iv d 1—3 Results:The overall response rate was 37.5% (12/32) and complete response rate was 3.1% (1/31), the partial response rate was 33.4% (11/32). The main toxicity was myelosuppression and alopecia. Leukopenia was observed in 81.6% of the patients, but grade 3 and 4 in only 12.5%. Anemia and throbopenia was observed in 21.8% and 35.1% of the patients respectively, alopecia in 100%. Other side effects were uncommon. Conclusions:This study shows that the regimen of ELF is effective and tolerable for treatment of advanced gastric cancer. [

Objective To detect and analyze the levels of preoperative serum carcino-embryonic antigen (CEA) and CA15-3 in early invasive breast cancer patients and their correlation with pathological parameters. Methods Electrochemical luminescence immunoassay (ECLI) technology was used to detect serum levels of CEA and CA15-3 in 223 cases of early invasive breast cancer patients, 109 patients with benign lesions, and 30 cases of heath control. Immunohistochemical (IHC) and fluorescence in situ hybridization (FISH) were used to detect the estrogen receptors (ER), progesterone recepter (PR), and its HER-2 pathological indicators.Besides, the correlation of serum CA15-3, CEA levels and pathological parameters was analyzed. Results The serum CA15-3 and CEA levels of Breast cancer patients [(22.27±15.11) U/ml, (5.03± 0.49) μg/L] were significantly higher than that of patients in benign lesion group [(14.13±3.04) U/ml, (2.72± 0.11) μg/L] (P< 0.05). CEA level of patients with histological grade Ⅲ was (6.34 ±0.93) μg/L, significantly higher than the level Ⅰ-Ⅱ (4.23±0.50) μg/L (P< 0.05). CA15-3 level was (19.26±15.08) U/ml in T1 tumors, and CA15-3 level was (28.73 ±11.53) U/ml in T2 tumors (P<0.05). The serum levels of CEA and CA15-3 between different histology, pathologic stage, lymph node status, ER, PR, HER-2, pathological characteristics had no significant difference (P>0.05). CEA positive rate of breast cancer group was significantly higher than that of benign lesions(13.5%vs. 3.7%, 26.5%vs. 1.8%, P<0.05). 30 cases of normal control group had no positive one. The joint monitoring sensitivity of CEA and CA15-3 breast cancer group was 9.4 %, the sensitivity was 0 in benign lesion group. There was significant difference (P < 0.05). Conclusion The changes of Serum CA15-3 and CEA levels in breast cancer patients can be considered as the judgment standard for early diagnosis, pathological staging, prognosis and clinical effect monitoring.

Objective To evaluate the serum changes in glioma patients, and in relations with clinicopathalogy parameters response to treatment and survival in patients with glioma via the examination of the significance of serum VEGF, Flt-1 and KDR levels. Methods Serum VEGF,Flt-1 and KDR levels were analyzed in patients of glioma before and after treatment, and patients with brain metastasis, as well as in healthy controls. Serum VEGF, Flt-1 and KDR levels were assessed by Enzyme-Linked Immunosorbent Assay(ELISA) and the data were processed by SPSS 11.5 for t-test and relevant analyses. Results Serum VEGF, Flt-1 and KDR levels were higher in patients with glioma than in healthy control (P =0.001, P =0.043 and P =0.045 respectively). Significant difference on levels of VEGF was found (P =0.032) comparing glioma group with brain metastasis group. The pretherapeutic serum levels of VEGF and Flt-1 were significantly different with disease recurrence or persistence after treatment (P =0.026 and P =0.038). There was significant correlation between the serum levels of VEGF correlated and that of Flt-1 and KDR (r =0.456 P

Objective To explore the diagnostic value of ultrasonography of fetal congenital cystic adenomatoid malformation of the lung (CCAM), and to predict the prognosis according to ultrasonographic findings. Methods The chest of 19 fetus with CCAM was multi-sectionally scanned with two-dimensional ultrasonography. The position, appearance and size of mass were observed, and complications were continuously followed. Results CCAM was pathologically confirmed in 13 fetus after induced abortion. One neonatal died, while CCAM in other 5 fetus disappeared before 36 weeks. The mass of typeⅠCCAM became smaller and smaller, and eventually disappeared. The echo-free spaces in typeⅡbecame smaller and fewer, and the strong echo weakened to the same level as normal lung. For type Ⅲ, the echo of solid mass weakened to the same level as normal lung, or transformed to typeⅡ gradually, and finally recovered to normal echo of lung as the gestational age increased. During follow up, there were 10 fetus (10/19, 52.63%) that lung adenoma cyst increased with the gestational age increased, and the heart, mediastinal shifted, pleural effusion, and (or) fetal edema were observed. Conclusion Ultrasound examination is a reliable method for the diagnosis of CCAM, and enable to predict the prognosis of the affected fetuses. If heart and mediustinum displacement, pleural effusion, hydrops fetal or other abnormalities exist, it's necessary to terminate the pregnancy.

Objective To investigate the diagnostic value of multiplex polymerase chain reaction (m-PCR) for diagnosing second infection of severe acute pancreatitis ( SAP), and to provide evidence for anti-infection treatment of SAP .Methods From January 2011 to December 2014 , thirty five patients of SAP were enrolled .Seven to fourteen days after SAP onset , patients′blood samples were taken and the presence of infection was determined by mP-CR.In the meantime, peripheral blood or the paracentesis fluid was cultured , and the result of culture was regard as golden standard to diagnose infection .Rseults The m-PCR could simultaneously detect 9 kinds of intestinal resident pathogenic bacteria , and the lower limit of detection was 10~1 000 copies.The detection rates were as follows (cultivation vs. m-PCR):staphylococcus aureus 6 vs 5 cases, staphylococcus epidermidis 11 vs 9 cases, enterococcus faecalis 2 vs 3 cases, enterococcus faecium 6 vs 7 cases, escherichia coli 19 vs 17 cases, klebsiella pneumoniae 2 vs 3 cases, pseudomonas aeruginosa 6 vs 4 cases, acinetobacter baumannii 2 vs 2 cases, malt narrow food aeromonas 4 vs2 cases.The 7th~14th days after SAP onset, the blood or paracentesis fluid culture was positive in 27 patients,and negative in 8 cases. And the m-PCR results were positive in 30 patients, and negative in 8 cases.The m-PCR results were positive in 30 patients, negative in 5 patients.The m-PCR results were positive in 3 patients who had negative culture results.In the remaining 32 cases, the results were consistent between the two detection methods .When the culture result was regarded as golden standard , the sensitivity, specificity and accuracy of m-PCR were 100%, 62.5%and 91.43%, respectively.The positive predictive value and the negative predictive value were 90%and 100%, respectively.It took (26 ±15) hours on average to obtain the result of culture method , and it took (102 ±32) hours on average to obtain the confirmative results .It took (12 ±8) hours on average to obtain the result of the m-PCR method.The time course of m-PCRwas significantly shorter than that of the traditional culture method, and the difference was statistically significant (P<0.05).Conclusions The m-PCR method can be used to monitor the bacterial infection in patients with SAP .The m-PCR method is a highly sensitive and rapid detection approach , which is worth of clinical application .
