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 study the significance of expression of hypoxia-inducible factor 1 alpha(HIF-1?) in gastric mucosal diseases. Methods Using tissue chip technique to creat tissue chip in 120 cases of vary gastric mucosal disease,and using S-P immunohistochemical methods to detect the expressions of HIF-1? in these tissue chips. Results The positive rates of HIF-1? was 28.3% in 120 tissue chips of gastric mucosal diseases. The positive rates of HIF-1? was 0, 10.0%, 40.0% and 63.3% in chronic superficial gastritis, chronic atrophic gastritis with intestinal metaplasia, chronic atrophic gastritis with dysplasia and intestinal type gastric cancer, respectively. The positive rates of HIF-1? of intestinal type gastric cancer and chronic atrophic gastritis with dysplasia were significantly higher than that in chronic superficial gastritis and chronic atrophic gastritis with intestinal metaplasia(P

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 observe the ultrastructure of biological living skin equivalent in vitro.Methods:Keratinocytes and fibroblasts were sourced from the back skin of legally aborted human foetus.Fibroblasts were seeded into bovine type I collagen gel and cultured for 3 days.Keratinocytes were seeded on the surface of collagen gel and cultured for another 2 days,then the equivalent skin was exposed to air-liquid interface to form a protective cornified layer.Histological structure and ultrastructure of the equivalent skin were observed by light microscope and transmission electron microscope.Results:The morphogy of equivalent skin of full thickness consisted of epithlium and dermis.Epithelium was made up of stratum basale,stratum spinosum,stratum granulosum and stratum corneum.lntercellular bridge existed within the cells of different layers.Some ultrastructures in epithelium such as desmosome,Lamelle,tonofibrils and lipid droplet were found in the equivalent skin.Conclusion:Tissue-engineered skin may have the features of natural skin.

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 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.

AIM: To observe the effect of microRNA-16 (miR-16) on the megakaryocytic differentiation of K562 cells, and to explore the potential mechanism.METHODS:miR-16 was over-expressed or silenced by transfection with miR-16 mimics or inhibitor in K562 cells.The level of miR-16 was detected by real-time PCR.The expression of CD41, CD42b and CD61, as megakaryocytic differentiation markers, was detected by flow cytometry.The effect of miR-16 on the expression of myeloblastosis oncogene ( MYB) was measured by Western blotting, and flow cytometry was performed to confirm whether the effect of miR-16 on expression of CD41, CD42b and CD61 was mediated by MYB.RESULTS:Transfection with miR-16 mimics dramatically elevated the level of miR-16 and the expression of CD41, CD42b and CD61 in the K562 cells.Transfection with miR-16 inhibitor decreased the level of miR-16 and the expression of CD41, CD42b and CD61 in the K562 cells (P<0.05).The expression of MYB was regulated by miR-16, and MYB silencing reversed the regulation of CD41, CD42b and CD61 induced by miR-16.CONCLUSION:miR-16 regulates the megakaryocytic dif-ferentiation of K562 cells by targeting MYB.

Objective To evaluate the cost-effectiveness of entecavir and lamivudine in treatment of early stage acute on chronic liver failure (ACLF),and analyze the predictive factors.Methods Forty nine patients with early ACLF were enrolled.Of which,28 patients were treated with entecavir,and 21 patients were treated with lamivudine.Mortality,length of hospital stay,cost,liver function,coagulation function,and model for end-stage liver disease (MELD) score were compared between two groups.Pharmacoeconomic evaluation was taken using cost-effectiveness analysis and cost minimization analysis.Results Mortality,length of hospital stay and cost had no significant difference between two groups.Ratio of costeffectiveness in lamivudine group was higher than that in entecavir group.Cox analysis showed that primary peritonitis and MELD score at the end of the second week were the main predictive factors.Conclusions Entecavir cannot improve the survival rate of early stage ACLF compared to lamivudine,but may provide economic benefit to patients with early stage ALCF.
