OBJECTIVE:To explore the role of clinical pharmacists on pharmaceutical care for allergic reaction caused by ox-aliplatin. METHODS:Clinical pharmacists conducted pharmaceutical care for a patient with oxaliplatin-induced allergic reaction, and suggested stopping taking oxaliplatin,giving Dexamethasone injection 5 mg and then slowing down injection speed. RE-SULTS:Physicians adopted the suggestions of clinical pharmacists. Allergic reaction relieved 5 min after giving Dexamethasone in-jection. The patient didn't suffered from this allergic reaction again under tight supervision. CONCLUSIONS:Oxaliplatin is often used for tumor therapy. Medical staff should be familiar with the prevention,diagnosis and treatment of ADR,evaluate oxaliplatin chemotherapy plan in advance and screen high risk allergy factor. The participation of clinical pharmacists in pharmaceutical care contribute to ADR monitoring and promote safe and rational drug use in the clinic.

OBJECTIVETo separate and characterize aqueous extracts of Salvia miltiorrhiza and Carthamus tinctorius to efficient, high-throughput and strong polar components, to observe effects of their aqueous effective components compatibility on rat myocardial ischemic reperfusion injury.

METHODMyocardial ischemic reperfusion injury model were established on SD rats by 40 min ligation of the left anterior descending artery and 120 min reperfusion. The rats were injected experimental drugs intravenously from femoral vein after 10 min ischemia. Rats were randomly divided into sham group (the suture around the left anterior descending coronary artery was not tied), model group, Danhong injection group (content of protocatechualdehyde is 0.05 g x L(-1), injection dosage equivalent to 1.80 g x kg(-1)), aqueous effective component of S. miltiorrhiza group (content of salvianolic acid B is 49 g x L(-1), injection dosage equivalent to 30.68 g x kg(-1)), aqueous effective component of S. miltiorrhiza group (content of hydroxysafflor yellow A is 31.76 g x L(-1), injection dosage equivalent to 17.87 g x kg(-1)), aqueous effective components compatibility of S. miltiorrhizae and C. tinctorius group (injection dosage is respectively 24.28 g x kg(-1) and 48.55 g x kg(-1)), each group have ten rats. Drugs were diluted with an equal dose of normal saline. The rats of sham group and model group were injected equivalent dosage of saline. The myocardial infarction size and the contents of serum cTnT and CK-MB were detected. The level of TXB2, 6-keto-PGF(1alpha) and platelet aggregation in blood plasma were investigated.

RESULTCompared with sham group, serum cTnT and CK-MB contents in model group increased significantly (P < 0.01). Compared with model group, myocardial infarction size and serum cTnT and CK-MB contents in aqueous effective component of S. miltiorrhiza group, aqueous effective component of C. tinctorius group and aqueous effective components compatibility of S. miltiorrhiza and C. tinctorius groups decreased significantly. Aqueous effective component of S. miltiorrhiza increased the level of 6-ke-to-PGF(1alpha), as well as decreased content of TXB2 and inhibited platelet aggregation (P < 0.01). Aqueous effective component of C. tinctorius also decreased the content TXB2 (P < 0.01). Improved extent of some detected markers in aqueous effective components compatibility of S. miltiorrhiza and C. tinctorius groups were better than that of Danhong injection group.

CONCLUSIONEffective components compatibility of aqueous extracts from S. miltiorrhiza and C. tinctorius may reduce myocardial infarct size and leakage of myocardial enzyme, and increase the level of 6-keto-PGF1alpha, so as to inhibit platelet aggregation and prevent thrombosis, the result of which is to reduce myocardial ischemic reperfusion injury.

Objective To summarize the surgical experience in robotic-assisted laparoscopic partial nephrectomy,and to investigate the efficacy and safety of this surgery.Methods The clinical data of 12 patients who underwent robot-assisted laparoscopic partial nephrectomy in Changhai Hospital from March to July in 2012 were analyzed.All the patients were male and the age range was 43-66 years.In 4 cases the tumors were in the left kidney,and 8 in the right.In 7 cases the tumors were in the dorsal part of the kidney,and 2 in the ventral part.There were 3,5 and 4 cases in the upper,middle and lower pole of the kidney respectively.Preoperative GFR test was normal in all cases.Kidney CT scan showed the maximum diameters of the tumors were 2.0-5.8 cm,with an average of 3.3 cm.The pre-operative stages in all cases were T1N0M0.Results The surgery was successfully completed in all cases.The mean duration of the surgery was 160-310 min,with an average of 242 min.The blood loss was 30-300 ml,with an average of 135 ml,and the intraoperative blood transfusion was unnecessary.The warm ischemia time was 20-49 min,with an average of 31 min.There was no intraoperative morbidity,and no conversion to open surgery.The postoperative length of hospitalization was 9-31 d,with an average of 14 d.Gross hematuria arose in 1 patient at 1 week after the surgery.The post-operative pathology showed renal clear cell carcinoma with Furhman Grade Ⅱ in 11 cases,and renal angiomyolipoma in 1 case.The maximum diameters of the tumors were 2.0-5.0 cm,with an average of 3.5 cm.The tumor resection margin was negative in all cases.Conclusions Robot-assisted laparoscopic partial nephrectomy is safe and effective for local renal tumors.This surgery has significant advantage over traditional laparoscopic partial nephrectomy,in terms of the resection of the renal tumors and the reconstruction of the kidney.

A porous composite particle (CP) was fabricated by the methods of emulsification and cross-link based on chitosan, alginate and collagen protein, and the tranexamic acid-loaded composite particles (TACP) was prepared by immersing the composite particle into the solution of tranexamic acid and by freeze drying. In the hepatic and splenic hemorrhage model of rabbits, CP and TACP were randomly used as haemostatic agents, and the Suxiaozhixuefen (Flashclot) was used as control. The corresponding hemostatic time and bleeding amount were observed respectively. The hemostatic time of CP and Flashclot were (2.48 +/- 0.88) min and (3.07 +/- 0.84) min, respectively, no significant difference was observed. However, the hemostatic time of TACP was (1.90 +/- 0.75) min, which was significantly shorter than that of CP and Flashclot (P < 0.05). In the splenic bleeding model of rabbits, similar results were obtained with these three kinds of hemostatics. These results indicated that the CP based on chitosan, alginate and collagen protein displayed similar hemostatic efficiency to Flashclot. However, the TACP might be one of promising haemostatic powders due to its more excellent hemostatic efficiency.
