Objective:To investigate the rational use of antiplatelet drugs and provide references for clinical utilization. Method:The sales amount,defined daily dose(DDDS) and daily expense(DDDc) of antiplatelet drugs in senile wards of our hospital were collected and analyzed,and other kinds of drugs which had drug interaction with aspirin were monitored by the Prescription Automatic Screening System(PASS) during 2007-2008.Result:Clopidogrel Hydrogen Sulphate Tablet was No.1 of all DDDs and Alprostadil Fat Emulsiom Injection was the most expensive of all the antiplatelet drugs,and the DDDs of aspirin was lower only than that of Clopidogrel Hydrogen;moreover,there were some problems in the clinical use of aspirin.Conclusion:The antiplatelet drug utilization in the senile wards almost meets with the guidelines and develops towards the direction to use new drugs with good action and few side-effects,but needs further standardization.

OBJECTIVE:To provide reference for the generalization of automatic unit-dose tablet sorting and counting machine (ATM) in hospital pharmacy. METHODS: The preparative work and the working procedure of the ATM were introduced, and the advantages, the causes of medication errors and the problems related to the application of the ATM were analyzed. RESULTS: ATM helped to enhance the dispensing efficiency, improve the sanitation of drugs, ensure drug safety to great extent and improve the drug control. However, sometimes it might bring about medication errors. 236 (0.48%) of the total 49 059 medical orders analyzed in our study were found to be of medication errors. CONCLUSIONS: ATM has great application value. The wide use of ATM is consistent with the tendency of pharmacy automation, yet its use remains to be further improved.

In recent years, the emergence of single-port laparoscopic technology promoted the development of the technology of laparoscopy, but deficiencies like equipment conflict or lack of triangulation severely hampered the clinical application of this technology. The appearance of single-port laparoscopic flexible instruments makes up for those deficiencies to a great extent. The element is to add a wrist joint to the tip of the instrument to form triangulation and reduce equipment conflict. But this technique is still in an early stage of development. The purpose of this article is to summarize the characteristics and problems of existing flexible single-port laparoscopic instruments, and to provide information for the further improvement, finally the future development was expected.

Liver transplantation is the only way to treat end-stage liver disease. In order to overcome the shortage of donor, marginal donors have been used widely, which bring about a series of problems. Machine perfusion can stimulate the circulation in vivo and is beneficial for the protection of liver. It could also improve the graft function and reduce postoperative complications, which makes it a hot spot in recent years. The aim of this study is to summarize the current status and prospects of application of machine perfusion on clinical liver transplantation.

Predicting protein-coding genes still remains a significant challenge. Although a variety of computational programs that use commonly machine learning methods have emerged, the accuracy of predictions remains a low level when implementing in large genomic sequences. Moreover, computational gene finding in newly sequenced genomes is especially a difficult task due to the absence of a training set of abundant validated genes. Here we present a new gene-finding program, SCGPred, to improve the accuracy of prediction by combining multiple sources of evidence. SCGPred can perform both supervised method in previously well-studied genomes and unsupervised one in novel genomes. By testing with datasets composed of large DNA sequences from human and a novel genome of Ustilago maydi, SCG-Pred gains a significant improvement in comparison to the popular ab initio gene predictors. We also demonstrate that SCGPred can significantly improve prediction in novel genomes by combining several foreign gene finders with similarity alignments, which is superior to other unsupervised methods. Therefore, SCG-Pred can serve as an alternative gene-finding tool for newly sequenced eukaryotic genomes. The program is freely available at http://bio.scu.edu.cn/SCGPred/.

This study shows the case of a patient with peroneus brevis tendon rupture in ankle fracture. The patient com-plained of swelling, pain and activity limitation in her right ankle caused by sprain. She was diagnosed with ankle fracture, supina-tion-adduction (Lauge-Hansen typing) by medical history, physical examination and imaging. The peroneus brevis tendon was not-ed complete ruptured when suturing the incision after ORIF, which was then repaired by "8" shaped suture. Based on literature re-view, the injury mechanism of the case may be because of overload inversion force toward to lateral inferior from the fracture of fib-ula on the peroneus brevis tendon. Additional attention should be paid to patients who suffered from an supination-adduction ankle fracture for whether peroneus brevis tendon tears before and during surgery.

Objective:To investigate the neuroprotective effect of cerebroprotein hydrolysate (CH) -Ⅰ on cerebral ischemia-reperfusion injury in rats and its mechanism.Methods:Eighty adult healthy male SD rats were randomly divided into sham operation group, model group, CH-Ⅰ intervention group and cerebrolysin (CBL) positive control group. The model of ischemia-reperfusion injury was induced by temporarily occluding the left middle cerebral artery with suture-occluded method. The CH-Ⅰ and CBL groups intraperitoneally injected with CH-Ⅰ and CBL at 0, 3, 6 and 12 h after reperfusion at the dose of 20 mg/kg. The sham operation group and the model group were injected with the same volume of normal saline. At 24 h after reperfusion, the behavior changes of the rats were detected by the modified neurological severity score (mNSS). The volume of cerebral infarction was detected by TTC staining. The morphology and structure of neurons in ischemic cortex were observed by Nissl staining. The apoptosis of neurons in ischemic cortex was detected by TUNEL staining. The expression changes of phosphorylated extracellular signal-regulated kinase (pERK) 1/2, phosphorylated mitogen-activated protein kinase/extracellular signal-regulated kinase (pMEK) 1/2, phosphorylated cAMP response element binding protein (pCREB) and brain-derived neurotrophic factor (BDNF) in the ischemic cortex were detected by Western blot.Results:At 24 h after reperfusion, the mNSS score and cerebral infarct volume in the model group were significantly higher and larger than those in the sham group (all P<0.001). The mNSS scores and cerebral infarct volumes in the CH-Ⅰ and CBL groups were significantly reduced compared with those in the model group (all P<0.05), but there was no significant difference between the CH-Ⅰ group and the CBL group. Nissl and TUNEL staining showed that the degenerative cell index and apoptotic cell index in the CH-Ⅰ group were significantly lower than those in the model group (all P<0.01), but there were no significant difference between the CH-Ⅰ group and the CBL group. Western blot analysis showed that compared with the sham operation group, the pMEK1/2, pERK1/2 and pCREB expressions in ischemic cortex were significantly enhanced and the BDNF expression was significantly attenuated in the model group ( P<0.05). Compared with the model group, pMEK1/2, pERK1/2, and pCREB expressions in the CH-Ⅰ group were significantly decreased (all P<0.05), and the BDNF expression was significantly increased ( P<0.05). Conclution:CH-Ⅰ can reduce cerebral infarct volume and improve neurological function, and its mechanism may be associated with the inhibition of the MEK-ERK-CREB pathway as well as the enhancement of BDNF expression.
