OBJECTIVE:To probe into the status quo and tendency of the utilization of anticoagulant drugs in our hospital. METHODS:The utilization of anticoagulant drugs in our hospital from 2004 to 2007 were analyzed statistically with regard to drug varieties,consumption quantity and consumption sum as well as DDDs. RESULTS:The consumption sum of anticoagulant drugs in our hospital increased year by year. Of all the anticoagulant drugs,leading the list in terms of consumption sum were ozagrel,low molecular heparin calcium and clopidogrel. CONCLUSION:The utilization of anticoagulant drugs in our hospital is basically in line with the current medication principle of anticoagulant drugs and the general medication trend both at home and abroad.

Objective To evaluate economic benefits and clinical effects of internal fixation treatment of severe rib fracture so as to provide objective basis for improving medical treatment for rib fracture.Methods A retrospective review was made on clinical data of 50 patients with severe rib fracture hospitalized from January 2009 to April 2014.With varied treatment modalities,the patients were assigned to operative group (n =13) and non-operative group (n =37).Variables were recorded including length of stay,total hospital charges,length of ventilatory support,off-bed time,duration of antibiotic use and incidence of complications and used to perform cost-efficiency analysis.Results Between operative and non-operative groups,length of hospital stay was (25.9 ± 8.2) days vs (35.4 ± 7.0) days,total hospital charges were (121 676.2 ± 10 991.1) yuan vs (148 724.5 ± 21 254.3) yuan,length of ventilatory support was (7.9 ± 2.8) days vs (14.1 ± 3.3) days,off-bed time was (14.3 ± 4.9) days vs (26.1 ± 6.5) days,duration of antibiotic use was (12.4 ± 3.3) days vs (21.2 ± 6.2) days and complications occurred in 2 cases vs 13 cases respectively.The findings were length of ventilatory support,off-bed time and duration of antibiotic use differed significantly between the two groups (P ＜ 0.05).Cost-effectiveness ratios based on subjective and objective measures were superior in operative group (1 962.52 and 3 925.03) over those in non-operative group (1 931.48 and 3 718.10),suggesting operative treatment could yield higher economic returns.Conclusion Internal fixation can accelerate bone healing in patients with severer rib fracture and cut down medical expense,which should be promoted in medical treatment.

Objective To observe the effect of Naoling decoction on the expression of iNOS in hippocamal CA3 region in rats with Alzheimer's disease (AD), and to explore the potential mechanism. Methods Forty SD rats were classified into 5 groups: a normal group, a sham operated group, an AD group, a Naoling decoction group, and a Naofukang group. The Alzheimer's disease model was established by injecting Aβ1-42 into the hippocamal in the rats. Expression of iNOS in the CA3 region was measured with immunohistochemical staining. Results Compared with the normal group, the expression of iNOS protein in the hippocampal CA3 fields in the AD group increased (P<0.05). Naoling decoction decreased the iNOS expression. Conclusion Naoling decoction can significantly reduce the expression of iNOS in the AD model rats, suggesting that Naoling decoction can be used for AD rats.

Objective To observe the effect of Naoling decoction on hippocamal histomorphology and the expression of amyloid precursor protein (APP) in CA3 region in rats with Alzheimer's disease (AD), and to explore the therapeutical and the potential mechanism. Methods Forty SD rats were classified into 5 groups: a normal group, a sham-operated group, an AD group, a Naoling decoction group, and a Naofukang group. Alzheimer's disease model was established by Aβ1-42 injected into the hippocamal in the rats. The faculty of learning and memory was evaluated by Morris water maze. The changes of cell morphology were detected by HE staining. Expression of APP in CA3 region was mea-sured with immunohistochemical staining. Results Morris water maze experiment showed that the escape latency of hidden platform in the AD group were delayed significantly (P＜0.05) and the average times of passing was decreased (P＜0.05). In the hippocampal CA3 field of the AD rats, HE staining and immunohistochemical test showed that pyramidal cells disturbed, neurons decreased significantly and expression of APP protein increased (P＜0.05). Naoling decoction treatment improved pyramidal cellular disorders and decreased APP expression. Conclusion Naoling decoction can distinctly improve the learning and memory ability, and reduce the expression of APP in the AD model rats, suggesting that Naoling decoction can be used for the treatment of AD in rats.

Antagonism, esterase isozyme ployacrylamide gel electrophoretic (EST-PAGE) and cluster analysis was used in the study of 14 strains of Ganoderma. The results showed that there were 18 bands of EST with different Rf. Cluster analysis at 50% similarity level showed that all strains could be clustered into five groups, the first included Xian zhi, Da xian 823, Nan han, Yuan zhi 6, Tian zhi, Han zhi; the second included Chi zhi 10, Chi zhi 12, Chi zhi, Ri ben hong zhi; the third included Zi zhi, Hei zhi; the fourth included Xue zhi; the fifth included Bai zhi. And this result was similar to the result of antagonism and morphological characters. Because of its stablity, the technique of EST can be used for identification of Gamoderma.
