Ictal semiology is essential for the pre-operative evaluation of candidates for epilepsy surgery. We propose an ictal sign of temporal lobe epilepsy (TLE) termed tonic-automotor (TA), defi ned as contralateral tonic spasm of upper limb associated with ipsilateral hand automotor seizure and often accompanied ipsilateral head turning. We assessed the occurrence and lateralizing/localizing value of TA in TLE, we analyzed 129 seizures in 41 patients with TLE: 90 seizures in 30 patients with TLE of hippocampal sclerosis (TLE/HS) and 39 seizures in 11 patients with TLE of other lesions (TLE/ non-HS). When compared with unilateral automotor seizure and unilateral tonic spasm, TA occurred more frequently in TLE/HS patients (40% vs 10% and 16.7%). In addition, 24 seizures in 12 patients with TA were observed only in TLE/HS patients and contralateral to the seizure focus based on the side of tonic spasm. However, there was no signifi cant difference in the TLE/HS between dominant side and nondominant side. In addition, TA sign occurred relatively early in the ictal phase. Thus, TA may be a more reliable lateralizing sign of epileptogenic zone and a semiologic marker of TLE/ HS patients.

The composition of intestinal microflora is closely related to the occurrence and development of colorectal cancer (CRC). Among them, Fusobacterium nucleatum (Fn) has been proved directly related to the recurrence, metastasis and chemotherapy resistance of CRC. Therefore, it is of great significance for the prevention and treatment of colorectal cancer by the exploration potential anti-Fn drug targets and discovery small molecule drugs. However, no selective anti-Fn small molecule inhibitors have been reported so far as well as their anti-Fn thereby "anti-Fn further anticancer" mechanisms are unclear. Herein, this article reviews the potential therapeutic targets and small molecule ligands of Fn in order to provide a reference for the development of anti-Fn and anti-CRC small molecule drugs.

Objective To understand of work status and professional ability of ICU specialist nurse,test their specialist ability level,improve and enhance the specialist nurse management to maximize their roles in promoting the development of clinical nursing.Methods 38 ICU nurse specialists who have got the nursing credentials more than one year were surveyed through self-questionnaire about working conditions,including general conditions,work status,income,self-assessment of specialist ability in future.Results 100％ ICU trained the younger nurses,and discuss the nursing management and problems.36.8％ nurses participated clinical nursing and night shift,5.3％ nurses have never joined ward inspection.Rates of reaching the standard were higher and above the 90％ in those three aspects: practice in clinical work,guided teaching and providing information for family member.Grasp of academic knowledge (86.8％),theory teaching (86.8％) and providing academic knowledge for nursing (86.8％) needed to be improved.Paper searching and reading (65.8％),paper writing (57.9％) and research design (47.4％) were relatively lower.Conclusions Culturing and using the specialist nurses in ICU lack the program and rationality; Specialist nurses have vague role; talent team was lacked; pay status needs increased; research ability needed enhanced; admittance,training and using criteria were lacked.

Immune thrombocytopenia purpura (ITP) is a disorder mediated by antiplatelet antibodies and characterized by accelerated destruction of platelets and impaired platelet production. The mainstay therapies for ITP have included corticosteroids, the immune globulin intravenous immunoglobulin and IV anti-D (monoclonal antibodies against the D antigen of the Rh system), vinblastine or a monoclonal anti-CD20 antibody that transiently depletes CD20(+) B cells, danazol, cyclophosphamide and even splenectomy to refractory one. Most of ITP patients responded to those treatment, while more than 30% of whom may relapse sooner or later. The recombinant forms of human TPO were discontinued from human use in clinic because recipients of these agents developed significant thrombocytopenia secondary to production of neutralizing antibodies that cross-reacted with endogenous TPO. All above mentioned treatments have side effects and severe infection may arise post splenectomy. The more powerful treatment with less side effects are needed. There are two TPO receptor agonist, AMG531 and Eltrompobag, have approved in Europe for the treatment of ITP. Both of them can improve the differentiation of megakaryocyte and platelets production. Combination treatment including pancytoprotector shows good effect in the treatment of refractory and relapsed ITP in China. Altogether, individual treatment of ITP is the contemporary trend in both clinical and preclinical practice. In this review the pathogenesis of ITP and its clinical therapies were reviewed, the individual regiments for treating ITP patients were discussed.

Objective:To determine whether ox-LDL (oxdized low-density lipoprotein) is highly deposited on the uremic vessel wall and its influence on the vascular remodeling. Methods: Segments of radial arteries were obtained from 21 uremic subjects during the operation of A-V fistula prior to hemodialysis. Segments of internal thoracic arteries of similar diameter were obtained from patients with benign chest tumors as control.The vascular lesions and ox-LDL, CD68,MCP-1, eNOS,ET-1, PCNA,FN on the vessel wall were determined by means of H-E stain and immunohistochemistry. Results： With H-E stain,atherosclerotic plaques were found in the radial arteries of 4 uremic patients. The middle layer of the arteries in uremic patients were obviously thickened, and the T/D　(thickness of the wall/external diameter) ratio was significantly higher than those in control group(P<0.01). ox-LDL,CD68,MCP-1, ET-1, PCNA,FN on the vessel wall in uremic patients were much higher than those in control group (P<0.01). Moreover, ox-LDL on the vessel wall was positively related to the expression of other above mentioned substances on the vessel wall (P<0.01). Whereas the expression of eNOS on the vessel wall was lower than control group (P<0.01),and was negatively related to ox-LDL on the vessel wall(P<0.01). Conclusion: ox-LDL is an important factor contributing to uremic vascular remodeling by increasing the migration,adhesion and infiltration of monocyte,the proliferation of vascular smooth muscle cell and dysfunction of endothelia.

OBJECTIVETo find a convenient and exact method for evaluating acrosome reaction in human spermatozoa.

METHODSThe semen of the normal male was mixed and then divided into 6 groups. Coomassie brilliant blue (CBB) staining, chlortetracycline (CTC) fluorescence staining and acid phosphatase (ACP) detection were used for morphological observation and data analysis of the acrosome status of the human sperm treated with or without progesterone.

RESULTSThere were obvious morphological differences between the acrosome-reaction and acrosome-intact spermatozoa in CBB staining and CTC fluorescence staining, and significant differences were observed between the experimental and control spermatozoa by the three methods (P < 0.05).

CONCLUSIONAll the three methods can be used to assess acrosome reaction in human spermatozoa, but Coomassie brilliant blue (CBB) staining is much more convenient and stable.

The aim of this study was to investigate the curative effect of amifostine (AMF) combined with recombinant human erythropoietin (rhEPO) on the aged patients with myelodysplastic syndrome. Two aged MDS patients (one aged 91; another 86) were treated with amifostine and rhEPO over a period of 4 weeks. The results showed that a short-term curative effect was observed and transfusion interval was prolonged in both patients after 4 week treatment with 5 x 0.4 g AMF plus 3 x 6,000 U rhEPO per week. The reticulocyte count in MDS-RA patient returned to normal at first week of treatment and still remained in normal level for 4 weeks; leukocyte, hemoglobin and platelet values in peripheral blood of MDS-RCMD patient obviousby increased, the abnormally increased reticulocyte value displayed a decrease trend after amifostine plus rh-EPO treatment. In conclusion, amifostine plus rhEPO may have a good therapeutic effect for aged MDS patients, and its clinical long-term curative effect still needs further evaluation.

The present study was aimed to investigate the damage effect of hepatocyte growrh promoting substance (HGS) on the HL-60 cell DNA in vitro and to explore the possible mechanism underlying the effect. Experiment was divided into 3 groups: one was control group, in which 0.9% NaCl solution was added, and other two were experimental group 1 and group 2, where 22.5 microg/ml and 40 microg/ml HGS were added, respectively. HL-60 cell growths were compared between groups with and without HGS. Single cell gel electrophoresis (SCGE) was used to detect DNA damage of HL-60 cell. DNA electrophoresis was used to detect the apoptosis of HL-60 cells caused by HGS. The results showed that the inhibitory effects of HGS on growth of HL-60 cells were observed in group with 22.5 microg/ml and group with 40 microg/ml after culture for 2 days, the DNA ladder and the apoptosis of HL-60 cells occurred in these 2 groups on day 2 after addition of HGS, the counts of HL-60 cells with comet tail in these experimental groups were found to be more increased in comparison with control group. In conclusion, the HGS can inhibit the growth of HL-60 cell and the apoptosis of HL-60 cells should be induced through pathway of DNA damage caused by HGS.

The objective of this study was to explore the effect of amifostine (AMF) in treating patients with idiopathic thrombocytopenic purpura (ITP) and its adverse effects. 17 ITP patients (aged from 13 to 92, mean 65 years) were treated with AMF and their therapeutic regimen was following: 0.4 g AMF was dissolved in 100 ml physiological saline, the intravenous drop was performed at day and lasted 5 days per week, with interval 2 days, 4 weeks were considered as a course of treatment. The results showed that the normal counts of platelets were observed in 17 ITP patients after 1 course of treatment, and remained unchanged for 2 months following stop of therapy. In that time, no any drugs such as hormonal preparation, gamma-globulin, blood transfusion and so on were given in all treated patients, the main adverse effect of AMF was discomfort in digestive system that all patients could endure. Therefore, the patient's life quality was obviously improved. It is concluded that the AMF has been initially and successfully used to treat ITP patients with positive response, and may be considered as a safe-effective drug for treating old patients with ITP, but the long-term effect and pharmacological mechanism of this drug needs further evaluation.
