OBJECTIVE:To observe the effect of cinepazide maleate combined with Xueshuantong injection on the blood sup-ply of subcutaneous artery after flap transplantation. METHODS:68 patients with cross-regional combined with flap transplantation in extremity soft tissue injury were randomly divided into observation group and control group. The roast lamp irradiation in the flap transplantation and ambulation prohibited,alcohol and tobacco prohibited were carried out as rountine treatment. On this basis, control group was treated with cephalosporins,papaverine and low molecular dextran after flap transplantation. Observation group was treated with cinepazide maleate 8 ml adding into 0.9% Sodium chloride injection 250 ml by intravenous infusion,once a day+Xueshuantong injection 5 ml adding into 0.9% Sodium chloride injection 250 ml by intravenous infusion,once a day. The course for both was 14 d. The clinic data was observed,including blood rheological indicators (whole blood high cut,whole blood cut, whole blood low cut,plasma viscosity and RBC aggregation index),and coagulation function indicators [thrombin time(TT),acti-vated partial thromboplastin time(APTT),prothrombin time(PT)and GB normalized ratio(INR)] before and after 1,3 and 7 d of surgery,and the postoperative incidence of arterial vascular crisis within 7 d and adverse reactions. RESULTS:There was no sig-nificant difference in the incidence of arterial vascular crisis in 2 groups after 1 and 2 d of surgery(P>0.05);the incidence of arte-rial vascular crisis in 3,4,5,6 and 7 d in observation group was significantly lower than control group,with significant difference (P<0.05). After 3 and 7 d of surgery,blood rheological indicators and 1,3 and 7 d of coagulation function indicators in 2 groups were significantly better than before,and observation group was better than control group,with significant difference(P<0.05). There were no significant difference in the incidence of adverse reactions between 2 groups(P>0.05). CONCLUSIONS:Cinepa-zide maleate combined with Xueshuantong injection can effectively improve the blood rheological indicators and coagulation func-tion indicators of patients,reduce the incidence of arterial vascular crisis,with good safety.

Objective Naringenin has a vast prospect of application because of its important biological activities .This study aims to explore the influence of different concentrations of naringenin on the growth of nasopharyngeal carcinoma CNE 2 cells and its ac-tion mechanisms. Methods Using the MTT method, we measured the effects of naringenin on the growth of CNE 2 cells after treated at the concentrations of 0, 0.005, 0.01, 0.02, 0.04, 0.06, 0.08, 0.1, 0.2, 0.4, and 0.8 mg/mL for 24, 48, and 72 hours.At 48 hours, we observed changes in the cycle of the cells treated with naringenin at 0, 0.02 and 0.04 mg/mL by flow cytometry, in the ap-optosis of the cells by Hochest 33258 staining and flow cytometry , in the level of reactive oxygen species ( ROS) in the cells by DCFH-DA staining, and in the mRNA expressions of C-fos, Bax and Bcl-2 by qPCR. Results Compared with the control group , naringe-nin at 0.02 and 0.04 mg/mL induced a low-level rise of ROS in the CNE2 cells (MFI:5186 ±183.50 and 5508 ±155.37, P<0.05), up-regulated the expression of C-fos (P<0.05 or P<0.01), and promoted the proliferation of the cells .However, naringenin at relatively high concentrations of 0.2 and 0.4 mg/mL significantly elevated the level of ROS (MFI:10758 ±179.82 and 11241 ±1 114.45, P<0.01), up-regulated the expression of Bax (P<0.01), down-regulated that of Bcl-2 (P <0.01), induced the apoptosis (P<0.01 ) and suppressed the proliferation of CNE 2 cells. Conclusion Within a concentration range of 0.005-0.8 mg/mL, naringenin may have two-way effects on the growth of CNE2 cells, a carcinogenic effect at a relatively low dose and a good anticancer effect at a relatively high dose .

Objective To investigate the findings and prognosis of head MRI and brain parenchymal lesions in patients with intracranial venous sinus thrombosis. Methods The clinical manifestations and imaging data of 41 patients with intracranial venous sinus thrombosis were analyzed retrospectively. According to the head MRI,the patients were divided into a brain parenchymal lesion positive group (n = 21)and a negative group (n =20). The clinical manifestations and the difference of the affected venous sinus in patients of both groups were analyzed. Results The proportion of dehydration,epilepsy,motor disorders,and psychiatric symptoms in the positive group were 28.6% (n =6)vs. 0% (n =0),57. 1% (n =12)vs. 15. 0%(n = 3),47. 6% (n = 10)vs. 5. 0% (n = 1),and 33. 3% (n = 7)vs. 5. 0% (n = 1),respectively. There were significant differences (all P < 0. 05). The proportion of the occurrence of superior sagittal sinus thrombosis in the positive group was lower than that in the negative group (47. 6% [n = 10]vs. 80. 0%[n = 16];P = 0. 031). At discharge,the proportion of complete recovery (modified Rankin score 0 -1)in the positive group was lower than that in the negative group (71. 4% [n = 15]vs. 100% [n = 20];P =0. 032). Conclusion Compare with the clinical symptoms of the positive patients,the patients with intracranial venous sinus thrombosis and those with negative brain parenchymal lesions are relatively minor,their prognoses are better,and the thrombi are more involved in superior sagittal sinus.
