Objective To investigate fracture patients' perception about pain and analgesic.Methods In-depth interview for 30 min was done for 20 fracture patients within 12 h after their admission.Data were analyzed based on Colaizzi phenomenological research method.Results Fracture patients underestimated the influence that pain had dosne to them.When they were suffering from pain,most of them chose to endure until they couldn't endure anymore.For analgesics,most of them chose to avoid from using them unless they couldn't endure anymore.Conclusions Pain management education should be done to help patients correct their bias about pain,know more about analgesics according to their personal conditions,and help them self-report their pain and manage their pain timely and properly.

Seizures may be the first or sometimes the only manifestation of patients with glioma in clinics. The aim of operation is to eliminate epilepsy far beyond mere resection of tumor mass. The underlyling mechanisms of glioma-associated epileptogenesis are poorly understood. Recently the theory of amino-acid like neurotransmitters in chemical synapse is gradually accepted. However, the molecular mechanisms remain to be further investigated on how glutamate release is regulated and how synaptic homeostasis in peripheral neurons is kept or disturbed. So detailed studies are needed to clarify specific molecular target and provide proper evidence for optimal antiepileptic drugs in glioma-associated epileptoge-nesis.

Objective To study the impact of imported filariasis cases on the elimination program in different areas of Shandong Province. Methods Dezhou was selected as former low endemic area and Yicheng as former high endemic area. Blood examination was carried out for both mobile population and local people for microfilariae(Mf). Mosquitoes were caught in field and dissected to count the ratio of those having laid eggs and the natural filarial infection rate. Mosquitoes reared at different temperatures were fed with Mf-positive blood and dissected after certain time period to observe the development of the larvae. The vectorial capacity and case transmission quantity were calculated and compared with those from different areas. Results The Mf positive rate of inflow population was 3.18% in average. No case was detected from 9 411 local residents after blood exam in Dezhou while 2 out of 692 local residents were found Mf positive in Yicheng. Mosquitoes'natural infection rate was 3.81% but no third stage larva was found. The shortest time period needed for the larva to develop into an infective stage was 16 days in Dezhou and 11 days in Yicheng. The time period from blood meal to egg-laying on average was 4. 95 days in Dezhou and 4.33 days in Yicheng. The ratio of vectorial capacity and case transmission quantity was 1:4.41 and 1:5. 82 respectively in Dezhou and Yicheng. Conclusion Filarial transmission seems unlikely in Dezhou for its low vectorial capacity and low transmission quantity resulted from low and evidently fluctuating temperature in the north. A low level filarial transmission may be possible in former high-endemic area such as Yicheng if there are as many imported cases as in Dezhou.

Background and Purpose:Prostate cancer is one of the most common cancers and the second leading cause of cancer-related death in Europan and North American males.The incidence of prostate cancer has also been increasing during the past few decades in China.It is widely accepted that this heterogeneity,which results from the tumor progression driven largely by genomic instability(genetic and/or epigenetic alterations)of tumor cells in primary tumor,endows specific populations of tumor cells with the unique character needed for invasion,migration,and metastasis colony formation in other organs and only these subpopulations possessing thost character can survive the potentially destructive journey from the primary tumor to the sites of metastases.The purpose of the present study was to explore the genes associated with invasion and metastasis of human prostate cancer cell line PC-3M in nude mice.Methods:After PC-3M cells were inoculated into orthotopic site(prostate) in a male nude mouse for two months,tumor cells were isolated from the primary tumor and lymph node metastasis,separately.Cell invasion and adhesion ability in vitro were first compared between two cells.Then metastasis-related genes differentially expressed between them were analyzed by utilizing cDNA microarray technique.Results:The in vitro cell invasion and adhesion potential of tumor cells from lymph node metastasis was significantly higher than those from primary tumor by 2.5 fold and 1.5 fold,respectively.Metastasis-related genes differentially expressed between those two sublines were identified,all of them were up-regulated in the tumor cells from lymph node metastasis and could be categorilized: 1.genes encoding cellular matrix-degrading proteolytic enzyme including cathepsin and MMP.2.genes encoding transcription factors.3.genes related to heterotypic adhesion of tumor cells.4.genes encoding cell surface receptors.Conclusions:There are significant differences in invasion and adhesion potential between cells from primary tumor and those from lymph node metastasis.Some differentially expressed molecules might be playing pivotal roles in promoting tumor cells to migrate from primary tumors to distant metastases,which may be helpful to elucidate the possible mechanism of metastasis in prostate cancer.
