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.

Aim: To compare the stability of Endostar~(TM) and endostatin under different temperatures and pH using polyacrylamide gel electrophoresis( PAGE) and Western blot and to compare the activity of Endostar kept at 4 ℃ and 37 ℃ by inhibition of endothelial cell proliferation. Methods: Endostar and endostatin expressed by Phicha pastoris were kept at 4 ℃, and 37 ℃ for 96 hours, respectively. The electrophoresis of the samples was detected by reduced and non-reduced PAGE. The results were further confirmed by Western blot with rabbit anti-Endostar polyclonal antibody. The inhibitory effect of Endostar stored at different temperatures on HUVEC was also exam-ined by cell-based assay. Results: Single band at 20 kD was detected in all lanes of SDS-PAGE gel loaded with endostatin and Endostar samples under reducing condition. In acidic native PAGE with three different pH values, endostatin showed a smear characteristic, whereas Endostar showed a unique band in acidic non-continuous native PAGE. Although the smear phenomenon was also observed under two conditions of constant native elec-trophoresis, the major band of Endostar could be detected. Similar electrophoretic behavior was found for endosta-tin and Endostar stored at both 37 ℃ and 4 ℃ . Western blot showed similar results to those by PAGE. Furthermore, Endostar stored at these two temperatures also had identical inhibitory effect on proliferation of HUVEC. Conclusion: Endostar and endostatin exhibit similar thermostability at regular conditions, but Endostar was more stable than endostatin expressed in P. pastoris under acidic condition.

Objective To explore the prognostic risk factors of low level malignant obstructive jaundice treated with transhapetic biliary drainage.Methods The clinical data of 142 patients with low level malignant obstructive jaundice received percutaneous transhapetic biliary drainage management from January 2010 to June 2013 were retrospectively analyzed.The study parameters included gender,age,tumor type,preoperative obstructive time,preoperative infection,drainage method,Child-Pugh grade,serum total bilirubin (TBIL),albumin (ALB),serum creatinine (SCr),the postoperative declining degree of bilirubin and postoperative antineoplastic therapy.The prognostic risk factors were evaluated.Results Single variable analysis showed that preoperative infection (P =0.006),Child-Pugh grade (P =0.004),SCr (P =0.043),the postoperative declining degree of TBIL (P =0.001) and postoperative antineoplastic therapy (P =0.015) were the related factors for survival time.The further Logistic regression analysis showed that preoperative infection (OR =3.729,95％ CI 1.332-6.363,P =0.040),Child-Pugh grade ≥ 10 scores (OR =0.513,95％ CI 0.375-1.276,P =0.018) and postoperative antineoplastic therapy (OR =0.668,95％ CI 0.210-2.026,P =0.038) were the related factors for survival time.Conclusion In treating of low level malignant obstructive jaundice with transhapetic biliary drainage,the preoperative infection,Child-Pugh grade and postoperative antineoplastic therapy may be the important related factors that affect the patient's survival time,to evaluate the prognosis of these patients has important reference meaning.
