AIM: To observe the pathological role of 3-nitrotynosine (3-NT) on Escherichia coli LPS-induced vascular hyporeactivity in rats and the therapeutic effect of antioxidants. METHODS: Forty male SD rats weighting from 200 g to 250 g were randomly divided into four groups: the control group (n=10); LPS shock group (n=10); uric acid-treated group (n=10); melatonin-treated group (n=10). 6 h after LPS shock, phenylephrine (0.5-2.5 ?g?kg -1) was applied intravenously to all groups and the percentage increase in MAP was detected, respectively. The concentration-response curve of aorta rings from all groups rats were obtained by cumulative addition of phenylephrine (PE), and PE E_ max, EC_ 50 were calculated. The concentrations of plasma malondialdehyde (MDA), nitrate/nitrite and 3-NT were assayed in all groups 6 h after LPS shock. RESULTS: The MAP level induced by PE significantly decreased to 54.60% in LPS shock rats compared with the control (P

China Pharmacist 2017;20(3):494-497
Objective: To evaluate the clinical efficacy and safety of ticagrelor in the patients with acute coronary syndrome ( ACS) . Methods:A retrospective study was applied to investigate the ACS patients treated with ticagrelor in our hospital from July to December in 2015. The basic information of patients, drug administration, platelet aggregation induced by ADP, major adverse cardio-vascular events ( cardiac death,nonfatal myocardial infarction,target vessel revascularization and stent thrombosis) , and adverse drug reactions ( ADR) were recorded. The incidence of end point events was calculated and the change of platelet aggregation induced by ADP before and after the drug administration was analyzed by SPSS statistical software. Results:A total of 161 patients were collected. The incidence of cardiovascular adverse events was 1. 2%, while the incidence of adverse drug reactions was 30. 4% including bleeding (15. 5%) without severe bleeding events and dyspnea (10. 6%) with 3 severe ones. The platelet aggregation rate before and after the ticagrelor treatment respectively was (54. 96 ± 14. 654)%and(24. 37 ± 13. 183)% in 122 patients with low reaction to clopidogrel( P<0. 01). Conclusion:Ticagrelor at the recommended dose can further reduce the platelet aggregation induced by ADP. In spite of high incidence of ADR, ticagrelor has slight ADR with good tolerance.

Objective To explore the curative effects of color Doppter ultrasound guided interventional therapy in pelvic cyst. Methods From July 2006 to June 2008,the color Doppler ultrasound guided transabdominal or transvaginal puncture was performed in 34 pelvic cysts among 32 diagnosed cases,absolute alcohol was injected into the cysts for sclerotherapy.Results Among 34 cysts,the treatment only failed in one cyst of one case because of the over ropy hydatid fluid,which was hard to be aspirated.All of the cases were followed up for three months.Twenty-seven cysts were cured after the first treatment,the cure rate was 79.4%(27/34).The maximum diameter of other 4 cysts decreased more than 1/2.The effective rate was 91.2%(31/34) after the first puncture.Finally,33 cases showed curative effect after the puncture therapy,the total effective rate was 97.1%(33/34).No serious complications were observed.Conclusion This therapy is a simple,accurately,safe and effective treatment for many indications.It's worthy to be recommended in the therapy of pelvic cyst.
10.Microtubule-destabilizing protein stathmin—a new target for gene therapy of cancer
China Oncology 1998;0(01):-
Stathmin is a novel member of microtubule-destabilizing proteins that play a critical role in the regulation of the dynamic equilibrium of microtubules during different phases of the cell cycle.The overexpression of stathmin was found in different type of cancer.Inhibition of stathmin expression in malignant cells may interfere with their orderly progression through the cell cycle.Overexpression of stathmin can affect the action of antimicrotuble drugs by markedly decreasing binding of paclitaxel,and increasing binding of Vinca alkaloids.In addition,stathmin provides an attractive molecular target for cancer therapy.It may be possible to combine adenovirus-mediated anti-stathmin ribozyme therapy with a chemotherapeutic agent such as taxol to obtain a more potent antiproliferative and antitumor effect.
