The incidence of venous thromboembolism in patients with ovarian cancer is much higher than other gynecologic cancers. Approximate 20%of ovarian cancer patients have hypercoagulable status during different phases of their disease. Ovarian cancer itself can induce hypercoagulability, but meanwhile the over activated coagulation system may promote disease progression. Coagulation system disorder is one of the most important prognostic factors in ovarian cancer. Recently, hypercoagulability becomes a hot spot in the ovarian cancer research ifeld. This article reviews the mechanism of hypercoagulability, its clinical implication and correlated treatment in ovarian cancer patients.

Objective:To observe the effect and influence of homocysteine and cystatin C in type 2 diabetes patients treated by Shuxuening injection combined with gliclazide. Methods: Type 2 diabetic patients were randomly divided into observation group and control group,and there were 30 cases in each group. The control group was given gliclazide hypoglycemic treatment, on the basis of the observation group to combined with Shuxuening injection. The course of treatment was 2 weeks. Efficacy , adverse drug reactions ,Ho-mocysteine ( Hcy) , Cystatin C ( CysC) and blood glucose ( FBG, PB) level change of two groups patients before and after treatment were compared. Results:The total effective rate of the observation group was 96. 67%, which was significantly higher than that of the control group (P<0. 05). After treatment,blood glucose and Hcy, CysC levels of the two groups of patients were significantly de-creased compared with before treatment (P<0. 05),and those of the observation group was much lower(P<0. 05). The incidence of adverse drug reactions between the two groups had no significant difference(P>0. 05). Conclusion:Shuxuening Injection on patients with type 2 diabetes mellitus has good curative effect, it can effectively reduce homocysteine and cystatin C levels, better control of blood glucose.

Objective To observe the injury to the heart,liver and kidney induced by hind limb ischemia/reperfusion(I/R),and to study the protective effect of H2S by attenuating this injury,in order to offer a theoretical basis for therapeutic application.Methods A model of hind limb I/R was reproduced.28 rats were divided randomly into 4 groups:normal control group(C,n=8),ischemia 4h group(I,n=8),ischemia 4h and reperfusion 4h group(I/R,n=6)and I/R+NaHS group(n=6)(NaHS can provide H2S for rats in vivo).The concentrations of CK,CK-MB,Tn-T,ALT,AST,Cr and urea in blood plasma were determined.The pathological changes in the heart,liver and kidney were observed with HE staining.Results The concentration of CK,CK-MB and Tn-T in I group increased significantly compared with that in C group,and that in I/R group was higher than in I group.No significant difference was found in plasma concentration of ALT,AST,Cr and Ur between C group and I group,while it they were increased significantly in I/R group compared with that in I group,and that in I/R+NaHS group were decreased significantly compared with that in I/R group.Pathological examination revealed pathological findings of injury to the heart,liver and kidney in I group,and even more serious injuries were found in I/R group than in I group,while the they were less marked in IR+NaHS group compared with that in I/R group.Conclusion Hind limb ischemia/reperfusion may result in injury to the heart,liver and kidney.H2S may attenuate injury to remote organs follawing hind limb ischemia/reperfusion.

BACKGROUND: Studies have shown that OCT4, SOX2 and HIWI can express in tumor tissues. OBJECTIVE: To investigate the relationship between the expression of stem cell transcription factors SOX2 and OCT4 in esophageal squamous cell carcinoma and their clinical characteristics and prognosis. METHODS: Expression levels of SOX2 and Oct4 were detected using immunohistochemical SP method in 77 cases of esophageal squamous cell carcinoma and 40 cases of adjacent cancer tissues confirmed by pathological examination, and then the their relationship with prognosis and clinical characteristics of the patients was analyzed. RESULTS AND CONCLUSION: Significantly higher levels of SOX2 and Oct4 were found in the esophageal cancer tissues than the adjacent cancer tissues (P < 0.05). SOX2 and Oct4 were highly expressed in the esophageal cancer tissues isolated from poorly differentiated, lymph node metastasis patients (P < 0.05). During the 2-year follow-up, the median survival of patients positive for SOX2 and Oct4 was only 24 and 21 months, respectively, which was significantly lower than that of negative patients (30 and 33 months, respectively). These findings indicate that the highly expressed SOX2 and Oct4 in esophageal cancer tissues are associated with the differentiation, metastasis and prognosis of the patients with esophageal squamous cell carcinoma.

Objective To explore role of functional neck dissection for lower collar-shaped incision at hair margin behind ear in the treatment of differentiated thyroid cancer. Methods The clinical data of 11 patients with thyroid papillary carcinoma who underwent func-tional neck dissection for lower collar-shaped incision at hair margin behind ear were retrospectively analyzed. Results The incisions of all patients were unseen in daily life and patients were satisfied with the postoperative appearances. No case of shoulder syndrome,postoperative local recurrence and distant metastasis was observed. Conclusion Functional neck dissection for lower collar-shaped incision at hair margin behind ear is effective in the treatment of differentiated thyroid cancer. Meanwhile it can obviously improve patients’ postoperative appearance and life quality,therefore it is worth clinical application.
