Objective To improve the curative effect of non-invasive therapy for biliary ascariasis to shorten the course of treatment and minimize the chance of invasive managements such as surgery and endoscopic therapy. Methods The sequential therapy was conducted as: intravenous injection of vitamin C → oral administration of acid drug → expel the worm in the biliary tract. Results For the 19 cases of biliary ascariasis, 15 responded to the conservative treatment after one course of treatment,2 responded to it after two courses, 1 after 3 courses and 1 did not. Conclusion Sequential therapy is effective, convenient and simple for biliary ascariasis and it can reduce the chance of invasive management.

Objective:To explore the diagnostic value of MRI in the diagnosis ofbone Eosinophilic GranulomaI. Methods:The clinical and imaging materials of 13 patients with eosinophilic granuloma of bone proved by histopathology were analyzed retrospectively.The imaging examination included plain films(n=13),CT(n=12),and MRI(n=13).Results:MR identified all lesions;With one exception,all lesions were hypointense on T1-Weighted images and hyperintense on T2-Weighted images;The lesions and associated soft tissue abnormalities were very conspicuous on short T1 inversion sequences and T1-Weighed post-contrast images;Follow-up MRI studies in two patients after chemotherapy showed decreased size and enhancement of lesions compared with the baseline studies.Three lesions were not identified on plain films.MRI showed greater abnormality than plain radiographs did.CT could identify all lesions also,and the main imaging findings included bone destruction,adjacent bone cortex involvement,periosteal reaction and sof t tissue mass or swelling. Conclusion:MRI can clearly demonstrate the extent of bone involved, the change of soft tissue and sequestrum.It can also acquire the anatomic and pathologicd details of bone and and soft tissue.But X-ray film and CT may improve the diagnostic and differential diagnostic accuracy.

Objective To investigate clinicopathological features of endometriosis-associated epithelial ovarian carcinoma.Methods Retrospective follow-up study,clinicopathological data from patients with ovarian epithelial carcinoma were retrieved,analyzed and compared.Among the 727 cases,34 were found to originate from endometriosis (group A),33 were found to have co-existing ovarian endometriosis (group B),and the remaining 660 had no ovarian endometriosis at all (group C).Result Seven hundred and twenty-seven epithelial ovarian carcinoma patients were identified and their ehnicopathological data retrieved.Sixty-seven (9.2%) of these cases were found to have coexisting endometriosis.The frequency of malignant tumors arising from ovarian endometriosis in this case series was estimated to be 0.87% (34/3890).The mean (standard deviation) age in groups A,B,and C were(47.2±1.3),(47.8±1.2),(51.2±0.4) years,respectively,with patients in group C being significantly older (P = 0.013).Patients with coexisting ovarian endometriosis were mostly diagnosed at stage Ⅰ (P = 0.000)and having subtype of clear-cell (P =0.000),while other patients were mostly diagnosed at stage Ⅲ (P =0.001),and having subtype of serous carcinoma (P =0.000).The estrogen receptor (ER) positivity was significantly lower in groups A and B than that in group C (22.2%,31.6% vs 43.9%;P =0.018),but the difference in positivity of progestogen receptor among the three groups did not reach statistical significance (22.2%,15.8% vs 35.5%;P =0.082).While the five-year overall survival rate for all patients was 55.6%,significant difference in overall survival among the three groups was found 78.9%,92.8%,51.9%,respectively,for groups A,B and C (P =0.000).Conclusion Patients of endometriosis-associated epithelial ovarian carcinoma,especially patients with tumors arising from endometriosis,were found to be younger,having a significant lower stage and a better survival,and were mostly diagnosed with the subtype of clear-cell.

Objective: To evaluate the frequency of MSI in epithelial ovarian tumors and its relationship with clinicopathologic features. Methods: Ninety fresh specimens of epithelial ovarian tumors, including 74 primary and 16 secondary tumors, were collected. Microsatellite analysis was carried out using 5 mono- and dinucleotide markers from the National Cancer Institute Consensus Panel by fluorescence-labeled polymerase chain reaction. Results: Of 90 epithelial ovarian tumors analyzed, 18 demonstrated a high level of microsatellite instability (MSI-H), 30 demonstrated a low level of microsatellite instability (MSI-L), and the remaining 42 exhibited microsatellite stability (MSS). Frequency of microsatellite instability (MSI) at loci BAT-25 was higher than that at any other loci. No correlation was found between MSI level and patient age, tumor type, tumor differentiation (P>0.05). But the microsatellite instability-high phenotype correlates with clinical stage.It tended to occur more frequently in early-stage tumors (P=0.03). Conclusion: The frequent MSI in epithelial ovarian tumors suggests that it is an early event to involve in the development of epithelial ovarian tumors.

Objective To explore the impact of hyperglycemia on Hypersensitive C-reaction protein (hsCRP),B-type natriuretic peptide(BNP) and ventricular remodeling in elder patients with acute myocardial infarction(AMI).Methods One hundred and twenty elder patients with AMI are divided into hyperglycemia group(blood sugar in admission ＞ 7.8 mmol/L) and non-glycemia group(blood sugar in admission ≤7.8 mmol/L).The levels of blood sugar in admission,hsCRP,BNP were detected.LVEF,LVEDD,LVESD,WMS were observed by cardiac echo in admission and two weeks after therapy.Results The blood sugar in admission,hsCRP and BNP of the patients in hyperglycemia group were (9.6 ± 0.6) mmol/L,(1 750.6 ±677.1) ng/L,(56.1 ±38.6) ng/L,higher than those in non-glycemia group (t =38.679 and P =0.000; t =11.941 and P =0.000; t =3.288 and P ＜0.01,respectively).LVEF,LVEDD,LVESD and WMS of patients in hyperglycemia group didn't show statistical significance before and after therapy.However,there were significant in hyperglycemia group (t =2.049 and P =0.043,t =2.836 and P =0.005,t =3.814 and P =0.000,t =2.086 and P =0.039,respectively).Conclusion Hyperglycemia can reduce the increase of hsCRP and BNP,which has an impact on hsCRP,BNP and ventricular remodeling in elder patients with acute myocardial infarction,but the mechanism need to further research.

Objective To investigate the influence of miR-203 on the proliferation and invasion of human esophageal squamous cell carcinoma cell line Eca109.Methods Double-stranded mimics of miR-203 were designed and transfected into Eca109 cells with Lipofectamine 2000;Eca109 cells transfected with nonsense microRNA mimics were taken as control.The proliferation ability of Eca109 cells was determined by calculating the cell population doubling time and the percentage of apoptotic cells;the invasion ability of Eca109 cells was determined by Transwell assay.Results In vitro experiment showed that,compared with the control group,Eca109 cells transfected with miR-203 mimics had a significantly longer cell population doubling time([26.1?0.5]h vs [24.2?0.6]h,P

Objective To summarize the clinical characteristics and evaluate the feasible treatments of primary breast lymphoma (PBL).Methods The clinical data of 34 PBL patients (age 24-79 years) who were treated in our hospital between April 2006 and December 2013 were reviewed.Of these 34 patients, 18 had stage ⅠE PBL and 16 had stage ⅡE PBL.Pathological types included diffuse large B cell lymphoma (29 patients), anaplastic large cell lymphoma (2 patients), marginal zone lymphoma (2 patients), and mantle cell lymphoma (1 patient).Two patients underwent surgery, four patients received chemotherapy alone, five patients received chemoradiotherapy, fourteen patients underwent surgery plus chemotherapy, and nine patients underwent surgery plus chemoradiotherapy.The 5-year overall survival (OS) and progression-free survival (PFS) rates were determined by the Kaplan-Meier estimator.Results During follow-up, 26 patients were alive without lymphoma and 8 patients had died by the end of follow-up (7 died from lymphoma and 1 died from chemotherapy-related hepatic failure).Among the 6 patients who relapsed, 5(83.3%) had recurrence within the first 2 years of treatment.In particular, 1 patient who had bilateral breast involvement developed left breast relapse after bilateral mastectomy and chemotherapy, 2 patients had bone marrow metastasis, 1 patient had lung and mediastinal lymph node metastases, and 2 had skin relapse.The 5-year OS and PFS rates of all patients were 75% and 75%, respectively.Conclusions Since PBL is a rare malignancy, its overall prognosis is fair and the incidence of local relapse is low with chemotherapy alone or in combination with other treatments.However, further studies on the development of more effective treatments will be required for patients who have failed the existing treatments.
