The morphology and anatomy of two genera, five species and one variety ofEquisetaceae produced in Shandong Province were studied under light and scanning electron microscope.There are remarkble differences between Equisetum L. and Hippochatete Milde in the type of stomas, at-tachments on the surface of stoma guard cells and the number of epithelial layers; and the presence of lat-eral xylem in all vasular bundle of Equisetaceae from Shandong. The results showed that they can be identi-fied taxonomically according to their inner structual and epidermal characteristics of stem between differentgenera, but with little difference among species of same genus.

In this study, cryopreservated platelets were transfused to 1560 patients. of them, 536 were patients with acute leukaemia, 285 with anemia, 253 with thrombocytopenia due to chemical or radicalized treat, 438 in perioperation, and 48 with DIC or hemorrhage of rupture esophagus varix. The storage time of cryopreserved platelets ranged from one week to thirteen months. Most of the cryopreserved platelets had not been washed before application and no obvious adverse-effects were observed except for garlic smell in patients' exhalation after transfusing cryopreserved platelets. The results showed that transfusion of cryopreserved platelets has a remarkable on effect hemostasis and can enhance the platelet count in peripheral blood. Compared with liquid-preserved platelets, cryopreserved platelets for clinic use have the following advantages:1) the potentiality of large stock, 2) much longer shelf life, 3) higher safety, 4) superior hemostasis effect, and 5) capacity to meet emergent massive clinic demand.

Objective To estimate the efficacy and safety of cryopreserved platelets in surgical patients.Methods 238 patients in recent years with hemorrhage or high risk of hemorrhage induced by thrombocytopenia or functional platelet defects during or after surgery, who had been transfused with cryopreserved platelets, were included in our study. The following items were recorded: bleeding time before and two hours after transfusion of cryopreserved platelets; the persist time of blood oozing from wound after transfusion; platelet count before and one hour after transfusion; platelet count before and immediately after surgery; and the number of patients with adverse transfusion reactions. The hemostatic efficacy was judged by the bleeding time and platelet count change.Results Bleeding times before and two hours after cryopreserved platelets transfusion were (9?3)min,(4?2)min respectively; blood oozing from wound stopped 0.5~2 hours after transfusion; the platelet level was elevated by(5~42)?10 9/L one hour after transfusion; the postoperative platelet count was decreased by(130?69)?10 9/L compared to preoperative count; four patients had urticaria and five had febrile reaction. The hemostatic efficacy was 95%(226/238) Conclusion Cryopreserved platelets function immediately to bring about the cessation of blood oozing from the wound,and elevation of peripheral blood platelet count.

Marine traditional Chinese medicine (MTCM) is an important part of Chinese medicine (CM),there are some differences in understanding of the current literature and the extension of the connotation of marine medicine,which leads to the definition dispute of MTCM,hindering clinical application and further development of MTCM.In this study,we explored the concept of MTCM in literature,discussed the attributes of ocean marine CM,summed up the differences between the land CM and MTCM over variety characteristics,effect of drug composition characteristics and biological activity characteristics,and discussed the connotation and extension of MTCM from three aspects of theoretical basis and the effect and source of the drug,leading to the formation of the narrow and broad concept of MTCM.The five kinds of disputes in the definition of MTCM were discriminated according to the concept and connotation,which provided a theoretical basis for the definition and the research of MTCM.Moreover,we also defined the English translation and its abbreviation as Marine Traditional Chinese Medicine (MTCM).

Objective To investigate the effects of the zinc finger protein A20 on LPS-TLR4 signaling pathways in severe acute pancreatitis(SAP) rats.Methods 24 SD rats were randomly divided into 3 groups:group A(the sham operation group),group B (the SAP group),group C (the SAP group treated with LPS).SAP model was induced by retro-injection of intraductal 5% sodium taurocholate into the biliary-pancreatic duct as previously described.The protein expression of A20,TLR4,NF-κBp65 and p38MAPK in pancreatic tissues was evaluated by immunohistochemistry.Results The positive area of A20 in pancreatic tissues was decreased in group B and group C compared with that in group A (t =17.234,19.698,all P < 0.05).On the contrary,the expression of TLR4,NF-κBp65 and p38MAPK in pancreatic tissues were up-regulated(t =15.909,20.432,16.543,18.629,22.105,19.006,all P < 0.05).A20 was decreased in group C than that in group B (t =14.894,P < 0.05),while TLR4、NF-κBp65 and p38MAPK were increased in group C than those in group B (t =14.047,15.582,17.070,all P <0.05).Conclusion The expression of A20 reduced and TLR4,NF-κBp65 and p38MAPK enhanced in the pancreas of rats with SAP,which indicated that A20 inhibited LPS-TLR4 signaling pathways which play important roles in the pathogenesis of SAP.

OBJECTIVE:To provide reference for clinical rational drug use. METHODS:Medication error(ME)cases report-ed from outpatient department from Oct. 2014 to Sept. 2015 in our hospital were analyzed,including ME category,classification, cause and proportion of persons who triggered or detected ME. RESULTS:Among 207 reports,there was no case of category A, 199 cases of category B,8 cases of category C,no of categories D-I. Among them,162 cases occurred in the links of prescrip-tions by doctors (78.26%),45 cases (21.74%) occurred in the links of dispensing prescriptions by pharmacists,the top 3 ME were improper usage(42.59%),improper administration route(40.74%)and inappropriate solvent(5.56%);the top 3 dispensing errors were variety error(40.00%),specification error(28.89%)and number errors(24.44%). The main causes for prescription errors were incomplete information system(56.17%)and drug information missing of doctors(43.83%);the main causes for dis-pensing errors were double specifications of drugs(35.56%),similar drug name(28.89%)and staffsntired(26.67%). In terms of the persons who triggered ME,the proportions of pharmacists,nurses,patients or their families were 97.58%,1.45% and 0.97%, respectively. CONCLUSIONS:Further strengthening information system and the on-the-job training for physicians and pharmacists can reduce the ME to some extent.

BACKGROUND:Studies have funded that reduced Wnt/β-catenin signaling is involved in the onset and/or progression of bone erosion in rheumatoid arthritis. It can lead to potential new treatment approaches of bone erosion by enhancing Wnt/β-catenin signaling pathway. R-spondin 1 may act as a Wnt agonist, but there is no study in human osteoblasts. OBJECTIVE:To verify the effect of R-spondin 1 on promoting differentiation and maturation of human osteoblasts by inhibiting DKK1. METHODS:S40-transfected human osteoblast lines, hFOB1.19, were treated with R-spondin 1, Wnt-3a and DKK1 to detecting the proliferation, alkaline phoshpatase activity and osteoprotegerin concentration. RESULTS AND CONCLUSION:R-spondin 1 had no effects on hFOB1.19 cel s. Wnt-3a upregulated the activity of alkaline phoshpatase, which could be enhanced by addition of R-spondin 1. R-spondin 1 could reduce the DKK1-mediated inhibition of alkaline phoshpatase activity in hFOB1.19 cel s. R-spondin 1 increased the concentration of osteoprotegerin, and moreover, the promotion of osteoprotegerin by R-spondin 1 alone was stronger than the inhibition by DKK1. These findings suggest that R-spondin 1 can inhibit DKK1 by Wnt/β-catenin signal pathway to promote the differential and maturation of human osteoblasts to excrete osteoprotegerin.
