In recent years,many medical institutions have opened a health management specialty about whose employment prospect students are not optimistic.But there is a huge gap in the position of China’s medicine employment market,and thus the contradiction in employment is very conspicuous.Therefore it is an effective way to resolve the contradiction by enhancing the student's overall quality of professional medical management and improving their professional competitiveness.

Epidermnoid cysts are henign, cutaneous cysts which commonly occur on face, neck and trunk. Retroauricular epidermoid cyst is rare reported which should be differentiated from auricle pseudocyst, lipoma, steatocystoma and fibroma. The hitopathological examination is a gold standard of diagnosis. Surgery of complete excision is the first choice of treatment methods.

BACKGROUND: Recombinant human erythropoietin (rhEPO) is a glycoprotein. Recent studies have demonstrated that rhEPO regulates many functional activities of neural cells. OBJECTIVE: To investigate the effects of different concentrations of rhEPO on proliferation of neural stem cells (NSCs) cultured in vitro. METHODS: Newborn Sprague-Dawley rat NSCs were harvested and cultured with serum-free culture medium containing different concentrations (5, 50, 500 U/mL) of rhEPO and 20 μg/L basic fibroblast growth factors (5, 50, and 500 U/mL rhEPO groups) and serum-free culture medium only containing 20 μg/L basic fibroblast growth factors (control group). After 7 days of culture, the cloning efficiency of NSCs was calculated. After 10 days of culture, neuron specific enolase (NSE)-and glial fibrillary acidic protein (GFAP)-immunoreactive cells were quantified. RESULTS AND CONCLUSION: In the rhEPO groups, cells proliferated rapidly, and the number of NSC microspheres was greater, in particular in the 50 U/mL rhEPO group, compared with the control group. NSCs grew faster in the 50 U/mL rhEPO group than in the control group. The number of NSE-and GFAP-immunoreactive cells was greater in the 50 U/mL rhEPO group than in the control group (P<0.01). These findings suggest that rhEPO promotes the in vitro culture and proliferation of NSCs, in particular 50 U/mL rhEPO.

Objective To investigate the tendency of diapause symptoms in breast cancer patients during their chemotherapy. Method Sixty-four breast cancer patients with chemotherapy participated in the study by using Pittsburgh sleep quality index (PSQI), the cancer fatigue scale (CFS), the self-rating anxiety scale (SAS) and the self-rating depression scale (SDS) to assess their sleep, fatigue, anxiety and depression at every first day from the second course to sixth one of chemotherapy. Results The diapause symptoms including fatigue, sleep disorders, anxiety and depression varied with the therapeutic course progressing. The conditions in sleep quality, fatigue and depression were the poorest at the diapause of the fourth course and the condition of anxiety was the poorest at the diapause of the third course. Conclusion The medical staff should attach importance to the patients'physical and mental problems brought by the process of chemotherapy, strengthen the regulation of psychosomatic symptoms during chemotherapic diapause, and give reasonable control and intervention before the symptoms deteriorating.

Radiotherapy is one of major cancer treatment methods.However,radiation resistance is an important reason to restrict the efficacy of radiotherapy and lead to treatment failure.In recent years,the relationship between the canonical Wnt signaling pathway and tumor radiation resistance has more and more attention of the scholars.This review summarized recent ten years findings concerning the canonical Wnt signaling pathway and tumor radiation resistance and tried to find some valuable rules or some internal relationships among different pathways by systemically analyzing.

The purpose of this study was to investigate the pharmacokinetic interaction between sunitinib and ramipril in rats. Eighteen male SD rats were divided into three groups, with each group being assigned to orally receive sunitinib, ramipril, sunitinib and ramipril, respectively, for ten days. Blood samples were collected at dif-ferent times after first-day and tenth-day administration. The concentrations of ramiprilat and sunitinib in rat plasma were determined by LC/MS/MS and the pharmacokinetic parameters were calculated and statistically analyzed. Compared with the administration of ramipril alone, after a single-dose combined administration, tmax of ramiprilat decreased significantly and t1/2 prolonged, while AUC0-∞ remained unchanged. These results indicated that the ab-sorption rate of ramiprilat increased and the elimination rate decreased, but total absorption degree was not changed. After multiple-dose administrations, CL of ramiprilat decreased and AUC0-∞ increased obviously. It sug-gested that accumulation of ramiprilat occurred in body and the drug elimination became slower. No obvious difference of sunitinib pharmacokinetic behavior was found when it was given in combination with ramipril after a single-dose administration or multiple-dose administration. Sunitinib decreased the elimination of ramiprilat after co-administration in company with drug accumulation in body after multiple-dose co-administration. The study showed that there were pharmacokinetic interactions between sunitinib and ramipril in SD rats.

The NF-kappaB pathway regulates the expression of over 150 target genes, e.g., cytokines, chemokines, leukocyte adhesion molecules and inducible effector enzymes. Consequently, it plays a crucial role in innate and adaptive immune responses, inflammatory response, stress responses, apoptosis and so on. IkappaB kinase (IKK) is the key of this pathway, and it owns a special structure which consists of catalytic subunit and regulatory subunit. Naturally, the activation of IKK needs the interaction of the two subunits and phosphorylation by its upstream kinases. Actually, there are two methods of activation of the NF-kappaB pathway, and both of the methods need the IKK complex. Given to the crucial role of IKK, researchers have isolated and synthesized amounts of IKK inhibitors, and these provide a great convenience to develop novel anti-inflammatory and anti-tumor drugs.

Objective Improve understanding the clinical features of bladder varices with portal hypertension. Methods A 63-year-old male manifested seven episodes of painless gross hematuria and had a 9-year history of liver cirrhosis. Physical examination was unremarkable. There was thrombocytopenia of 56 × 109/L. Ultrasound showed splenomegaly. Cystoscopy revealed a 3. 0 cm × 5.0 cm sized hemangiomatous on the left lateral and anterior wall of the bladder. Computed tomography angiography revealed the vesical varicose veins flowing into the inferior mesenteric vein and then to the splenic vein. Results The patient was diagnosed vesical varices, liver cirrhosis and portal hypertension. Performed perivesical devascularization and in ultrasound one month after the operation the variees disappears. Conclusion Vesical varices can occur in liver cirrhosis and portal hypertension patients without history of abdominal and pelvic operation, and can be treated by perivesical devascularization.
