Objective To analyze the influence of anticoagulants on platelet count .Methods A total of 5 patients with decreased platelet level ,detected by using haemocyte analyzer and samples anticoagulated by ethylene diamine tetraacetic acid dipotassium (EDTA‐K2 ) ,were enrolled ,and EDTA‐K2 ,sodium citrate ,heparin lithium ,sodium fluoride anticoagulated venous blood samples and fingers peripheral blood samples were collected and detected for platelet by using haemocyte analyzer and microscopic detection . Wright‐Giemsa′s stained cell smears were prepared and observed by using microscope .Results Platelet levels of anticoagulated samples ,detected by haemocyte analyzer and microscopic detection were obviously decreased ,and with large platelet aggregation ob‐served under microscope .Platelet levels of finger peripheral blood samples detected by haemocyte analyzer and microscopic detection were normal ,and without platelet aggregation observed under microscope .Conclusion Various anticoagulants could cause pseudo‐thrombocytopenia ,and fingers peripheral blood samples ,without anticoagulants ,should be used for platelet count to obtain accurate results .

OBJECTIVE:To extract phenolic acid from Salvia militiorrhiza by multi-stage countercurrent extraction technology. METHODS: The multi-stage countercurrent extraction technology and traditional single pot decocting extraction technology were applied to extract phenolic acid from S. militiorrhiza. The content of salianic-acid B was determined and energy consumption of these extraction technologies were calculated and compared. RESULTS: As compared with traditional single pot decocting extraction technology, multi-stage countercurrent extraction technology effectively decreased the degradation of active component, energy consumption and production cycle. CONCLUSION: Multi-stage countercurrent extraction technology is suitable for the production of S. militiorrhiza.

Pituitary adenoma with cerebrospinal fluid rhinorrhea is rare clinically. In this paper, through the analysis of a pituitary adenoma patient with initial symptom of cerebrospinal fluid rhinorrhea, we look forward to provide evidence for clinical diagnosis, so that we can avoid misdiagnosis.

OBJECTIVE:To probe into the utilization status of carbopenem antibacterials in our hospital.METHODS:The antimicrobial use density(AUD),the antimicrobial average daily cost(AADC),and the antimicrobial cost density(ACD) of carbopenem antibacterials used in our hospital during 2000～2006 were analyzed statistically using DDDs analytical method. RESULTS:DDDs and AUD of the carbopenem antibacterials used in our hospital showed an upward trend;the AADC of each kind was decreasing year by year but ACD presented an upward trend.CONCLUSION:Safe,effective,economical and rational use of carbopenem antibacterials is in the interest of protection of drug resources used for bacterial infection.

Objective To explore the relationship between preoperative right ventricular ejection fraction(RVEF) and postoperative complications in the elderly patients with lung resection. Methods RVEF was assessed in 118 consecutive aged patients before pulmomary resection by echocardiography, 64 of whom received RVEF measurement again 3 weeks after operation. Results Preoperative RVEF in patients with postoperative complications was obviously lower than that in patients without ones. The frequency of postoperative complications in patients with different preoperative RVEF(

0.05).CONCLUSION:The domestic tropisetron hydrochloride is equivalent to the imported one in terms of the efficacy and safety in the treatment of cisplatin-induced nausea and vomiting.

Objective To investigate the efficiency of intracerebroventricular injection of histamine receptor antagonists on mechanical pain threshold of neuropathic pain in rats. Methods The neuropathic pain rat model was established by partially ligation of the sciatic nerve in 30 rats. Two weeks later, histamine receptor 1 antagonist pyrilamine 1.5 μg or 15 μg was injected intracerebroventricularly in group P1 or P2, histamine receptor 2 antagonist ranitidine 10 μg or 100 μg in group R1 or R2, and normal saline in group C as the control. The pain threshold was measured. Results Compaered with group C,the pain threshold was signifigantly increased in group R1 and R2, especially in group R2 (P<0.05). Conclusion Histamine H2 receptor antagonist can increase pain threshold in rats with neuropathic pain.

Objective To study the therapeutical effects of compound Danshen injection combined with edaravone in treatment of acute cerebral infarction.Methods 130 cases of ACI were randomly divided into two groups, control group(65 case) and observation group(65 cases), control group were administered with edaravone injection, while observation group were administered with compound Danshen injection and edaravone injection, NIHSS score and Barthel index score were used for effects evaluation, meanwhile, serous levels of copeptin, NT-proBNP and Hcy were measured by ELISA assay.Results Observation group had a better effect on ACI care, compared with control group (P<0.01), and serum levels of copeptin,NT-proBNP and Hcy significantly improved both in the two groups ( P <0.01 ) , while, observation group had a better effects ( P <0.01 ) . Conclusion Combination therapy of compound Danshen injection and edaravone has a fabulous effect on ACI care.

OBJECTIVE:To explore the observation and nursing points of hemorrhage in intravenous thrombolysis after using alteplase. METHODS:128 patients underwent alteplase intravenous thrombolysis were selected as the research object. The occur-rence of hemorrhage in each part were observed within 48 hours after medication and nursed timely. RESULTS:128 patients re-ceived intravenous thrombolysis. 48 h later,26 patients suffered from hemorrhage complications (20.3%). Among them,there were 6 cases of nose bleeding (4.7%),8 cases of subcutaneous congestion (6.3%),6 cases of gingival bleeding (4.7%) and 6 cases of gastrointestinal bleeding(4.7%). There was no significant difference in the incidence of complications among those groups (P>0.05). The time of nose bleeding was (3.2 ± 1.3) h,the time of subcutaneous congestion (3.5 ± 1.2)h,the time of gingival bleeding(1.5±0.7)h,and the time of gastrointestinal bleeding(4.1±1.8)h. The time of gingival bleeding was earlier than that of other groups,with statistically significant difference(P<0.05). There was no statistically significant difference among other groups (P>0.05). CONCLUSIONS:In alteplase intravenous thrombolysis,nurses should closely monitor hemorrhage and complications, especially the complication of gingival bleeding. Find out the complications timely and nurse it as early as possible.
