BACKGROUND: There is yet no evidence about whether internal carotid artery stenting with cerebral protection devices is beneficial to reducing neurological complications. OBJECTIVE: To explore the safety and efficacy of carotid angioplasty and stenting with cerebral protection devices for carotid stenosis. DESIGN, TIME AND SETTING: Non-randomized concurrent control trial was performed at Hospital Affiliated to Medical College of Chinese People’s Armed Police Force from June 2005 to January 2007. PARTICIPANTS: Seventy-four patients with carotid artery stenosis underwent stenting, including 21 with cerebral protection devices (16 males and 5 females; average age of 66.4 years, range 50-79 years), and 53 with no protection devices (36 males and 17 females; average age of 69.2 years, range 52-83 years). METHODS: Size of cerebral protection devices was confirmed according to the diameter of normal vessel at distal carotid artery stenosis. The guide wire was sent into distal stenosis under guidance of pathway picture followed by cerebral protection device release. The stent passed over the stenosis and released to appropriate site. The protection device was removed when the stenosis was relieved confirmed by routine angiography. MAIN OUTCOME MEASURES: Features of stenting process; frequency of stroke attack perioperatively and during 12-month follow-up. All of them took periprocedual anticoagulation treatment, cerebral vascular angiograpgy. RESULTS: Seventy-six self-expandable stents were delivered in 74 patients with carotid stenosis. Twenty-one cerebral protection devices were employed including 8 Angioguard and 13 Filterwire. The patients without cerebral protection devices were predilated 20 times (37.7%) with the balloons, and all were postdilated; 3 cases (5.6%) developed brief decreased heart rate and hypotension after stent release. The patients with cerebral protection devices were predilated 6 times (28.5%) with balloons, and all were postdilated; 2 cased (9.5%) developed brief decreased heart rate and hypotension after stent release and 2 (9.5%) developed angiospasm. One patient (4.7%) with cerebral protection devices had cerebral infarction (4.7%) perioperatively and another had cerebral infarction (4.7%) during the follow up. While four patients in the group without cerebral protection devices had cerebral infarction (7.5%) perioperatively, and five had cerebral infarction (9.4%) during the follow up. There were no significant differences between two groups. CONCLUSION: The results of the study show that cerebral protection devices are not helpful to reduce neurological complications in patients with carotid artery stenosis after stenting.

The four natures are the basic properties of Chinese materia medica (CMM). At present, it is one of the research hotspots to reveal the scientific connotation of CMM property theory. Clarifying the formation process and influencing factors of the medicinal properties of each single herb in a long historical period is the basic condition for the induction and summary of common characteristics of TCM property theory. Through the textual research of ancient books and documents, combined with the research results of modern Chinese medicine science, this paper combs the influence factors in the formation of the medicinal properties of Lonicera japonica, and reveals its scientific connotation. That is to say, the formation of the medicinal properties of each single herb of TCM is the result of its efficacy material base, the efficacy reflected in the process of clinical treatment and the tendency of clinical medication in previous dynasties. Based on the above research, the cause hypothesis of single herb property is put forward for the first time. The hypothesis provides a reference for the theoretical study of medicine property of TCM.

Objective To investigate the effects of local application of NGF combined with Insulin on wound healing with Ⅱ degree deep scald and the expression of HIF-1α and VEGF in diabetic rats. Methods 60 male Wistar rats were used in the study by intraperitoneal injection of streptozotocin (STZ). Deep partial thickness scalding was engendered on the back of the rats after one month. Then these rats were random divided into group B (scalding of the rats with diabetes, n = 15), C (insulin control, n = 15), D ( NGF control, n = 15) and E ( NGF and insulin supplementation, n = 15). And group A ( nomal control,n = 15) was created by normal rats of partial thickness scalding. The wound area, wound healing rate, and grey of HIF-1α and VEGF immunohistochemistry staining were determined on the 3rd, 7th, 15th, and 21st day post scalding days (PSDs). Results Compared to those in groups A, B, C and D, the wound healing rate in group E increased significantly since the 7th PSD [(25.33 ± 2. 32 ) %, P ＜ 0.05]. The wound healing rate in group C and D increased significantly compared with group B [( 16. 68 ± 1.95 ) %, ( 18.29±1. 70)%, P ＜0.05]. Compared to group A, the group D increased significantly since the 15th PSD [(54. 84 ±3.60)%, P ＜0. 05]. The expression of HIF-1α and VEGF in group E began to increase slower than other groups after the 7th day ( P ＜0. 05 ). Conclusion Local application of NGF combined with Insulin could be beneficial to the regeneration of capillary vessel in the burn wounds of the rats with diabetes,as well as to accelerate wound healing by redress anoxia and decrease the expression of HIF-1α and VEGF.

Objective To investigate the effects of different doses of ulinastatin on platelet counts and function after normothermic cardiopulmonary bypass (CPB) in rabbits. Methods Fifty lung-ear white rabbits aged 5-6 months weighing 2.3-3.0 kg were randomly assigned to one of 5 groups (n = 10 each) : control group (group C) and4 ulinastatin groups (group U~1, U_2,U_3,U_4). The rabbits received ulinastatin 1×10~4, 3×10~4, 5×10~4 and 10×10~4 U/kg before CPB in group U~1, U_2, U_3 and U_4 respectively while equal volume of normal saline was given instead of ulinastatin in group C. All rabbits underwent CPB for 30 min at perfusion flow of 72-120 ml·kg~(-1) ·min~(-1). The rectal temperature was maintained at 36.5-37.5℃. Hemodynamic parameters were recorded and blood platelet count, platelet adhesion rate and platelet membrane glycopretein Gp Ⅰ b, Gp Ⅱ b, Gp Ⅲ a receptors were determined before CPB (baseline), at termination of CPB and at 1, 2 and 3 h after CPB. Results The platelet counts were significantly decreased after CPB in all 5 groups (P< 0.05), but there was no significant difference among the 5 groups. The platelet adhesion rates were significantly decreased after CPB as compared with the baseline value before CPB in all 5 groups but the platelet adhesion rates were significantly higher after CPB in group U_4 than in group C. The number of molecules of Gp Ⅰ b, Gp Ⅱ b and Gp Ⅲ a receptors was significantly decreased after CPB in all 5 groups. The number of molecules of Gp Ⅰ b, Gp Ⅱ b and Gp Ⅲ a receptors after CPB was significantly higher in group U_2, U_3 and U_4 than in group C, and there was no significant difference between group U_3 and U_4 . ConclusionUlinastatin 3×10~4-5×10~4 U/kg administered before CPB can inhibit breakdown of platelet membrane glycoprotein receptors. Ulinastatin 10×10~4 U/kg can preserve the platelet adhesion function.
