Objective To evaluate the accuracy of 64-slice spiral CT(64 SCT)in assessing the mild and severe stenosis of coronary artery.Methods A total of 72 patients suspected to suffer from coronary artery disease underwent orderly both 64 SCT and selective coronary angiography(SCAG).Volume rendering (VR),multi-planar reconstruction(MPR),maximum intensity projection(MIP)and transverse section wasused to analyze the 64 SCT data.The results were compared with those of SCAG to investigate the accuracy of the 64 SCT in assessing the≥50% stenosis of coronary artery.Results In the 720 SCAG segments of 72 patients.684 of them could be evaluated by 64 SCT.The evaluated rate Was 95.0%.Compared with SCAG,the sensitivity,specificity,positive predictive value,negative predictive value and accuracy rate was 67.4%,92.9%,69.5%,92.3% and 88.0% respectively.Conclusion The accuracy of 64 SCT in assessing mild and severe stenosis is relatively high and it can be used for screening patients with suspected coronary artery diseases as a non-invasive method.

Vasculogenic mimicry (VM) can promote tumor growth, invasion, and metastasis. The formation of VM is regulated by various proteins including epithelial cell kinase, phosphoinositide-3 kinase, and hypoxia-inducible factor 1. Local microenvironment also plays an important role in regulating VM formation.

Biliary complications are a serious problem in patients after liver transplantation, which often results in graft loss, the causes of bile duct stricture are complex. This paper reviewed the mechanism of bile duet stricture after liver transplantation. This complication maybe related with various factors such as liver arterial thrombosis, loss of blood supply of bile duct, warm iscbemia/preservation injury, chronic ductopenic rejection, cytomegalovirus infection, ABO incompatibility, and recurrence of primary sclerosing cholangitis.

Hypoxia inducible factor (HIF-1α) is a hypoxia response regulator,which is highly expressed in malignant tumors.Researches have shown that HIF-1α plays an important role in epithelial mesenchymal transformation.It can regulate epithelial mesenchymal transition through a series of signal pathways and mechanisms at many levels,to participate in the invasion and metastasis of tumors.To explore the mechanism of HIF-lα controlling epithelial mesenchymal transformation has important significance for the development of new,effective tumor treatment methods.

Objective To explore the factors related to the prognosis and survival duration of primary liver cancer patients after hepatectomy.Methods The data of primary liver cancer patientswho were treated by surgical resection were analyzed retrospectively.Kaplain-Meier method was used to evaluate survival rates.Log-rank test and Cox regression analysis were used to screen out related clinical phathology factors.Results The median survival time was eighteen months.Univarivate analysis showed that liver function Child-Pugh classification,cirrhosis,tumor size,HBV infection,AFP,portal vein tumor thrombus significantly correlated with survival rates (P < 0.05).Multivariate analysis showed that liver function Child-Pugh classification,tumor size,AFP and portal vein tumor thrombus were the independent prognostic factors of primary liver cancer (P < 0.05).Conclusion Many factors are related to the prognosis of primary liver cancer after operation.Liver function Child-Pugh classification,tumor size,AFP and portal vein tumor thrombus affect prognostic independently.

Objective To investigate the application of colposcope in cervical cancer screening in Yunnan ethnic minority areas.Methods The questionnaire survey was conducted on 641 women,and the data of the colposcopy and biopsy were reviewed retrospectively.The colposcopy and pathological diagnosis results were compared.Results The minority women thought colposcopy more acceptable was 78.64% (383/487).The colposcopy found suspected low-grade cervical lesions were 377 cases,high-grade cervical lesions were 245 cases,cervical condyloma were 15 cases,cervical cancer were 4 cases.The pathological results:278 cases of cervical intraepithelial neoplasia (CIN) Ⅰ,174 cases of CIN Ⅱ,55 cases of CIN Ⅲ,15 cases of cervical condyloma,4 cases of cervical cancer.The consistent rate of colposcopy and pathological examination was 68.17% (257/377) in low-grade lesions,89.39% (219/245) in high-grade lesions,cervical cancer and cervical condyloma was entirely consistent.Conclusions The colposcopy is more easily accepted in Yunnan ethnic minority areas,which could be a preliminary diagnosis of cervical lesions,cervical condyloma and cervical cancer.It has an important clinical application value in diagnosis of cervical diseases.

Objective The aim of this study was to investigate the effect of left-handed pantoprazole sodium on rat models of gastric ulcer generated by pyloric ligation .Methods The rat models induced by pylorus ligation were treated with a single intravenous injection of left-handed pantoprazole sodium .The gastric ulcer inhibition rate , volume of gastric juice, activity of pepsin, and level of serum gastrin were determined and gastric mucosa tissue was examined by pathology . Results The gastric ulcer index , volume of gastric juice , activity of pepsin and level of serum gastrin in the rats pretreated with left-handed pantoprazole sodium (0.9, 1.8, 3.6 mg/kg, i.v.) were significantly lower than those in the model group .The lesions of gastric mucosa were also improved in the pantoprazole-treated groups .Conclusions Left-handed pantoprazole sodium has remarkable protective effects on the gastric mucosa in rat models of gastric ulcer induced by pyloric ligation.

This is the case of a 26 year-old nulligravida with Polycystic Ovary Syndrome who developed severe Ovarian Hyperstimulation Syndrome (OHSS) during ovulation induction for Intrauterine Insemination (IUI). Three problems were encountered during treatment. The first was whether to convert a planned ovulation induction and IUI, that resulted in multiple follicular development, to an in vitro Fertilization - Intracytoplasmic Sperm Injection cycle. The second problem was determining what strategies are relevant in preventing OHSS in a woman at high risk for developing severe hyperstimulation. The third problem was why, when and how to employ abdominal paracentesis in the management of severe OHSS. Though the patient's course was turbulent, management was successful. She is now awaiting embryo transfer and, ultimately, motherhood.
