Objective To investigate the effect of intraperitoneal injection of thalidomide on pain behaviors in a mouse model of bone cancer pain. Methods 36 male C3H/HeJ mice were divided randomly into tumor group (n= 18) and sham group (n= 18) ,six mice from each group were chosen to examine the time course of changes in behavior after tumor cells inoculated to the bone. 2 × 105 osteosarcoma NCTC 2472 cells were implanted into the intramedullary space of the right femurs of mice to induce ongoing bone cancer related pain behaviors. The sham group was inoculated by α-MEM without any cells. On the day before inoculation,the tumor mice were divided randomly into tumor + thalidomide group and tumor + vehicle group. The sham group mice were further divided randomly into sham + thalidomide group and sham + vehicle group. Pain ethology indexes such as paw withdrawal mechanical threshold (PWMT) and paw withdrawal thermal latency (PWTL) were observed on 1 d before inoculation and on 3 d ,5 d ,7 d, 10 d, 14 d after inoculation. Results ( 1 ) At day 7 after the operation, compared with sham mice ( 1. 70 ± 0. 33 ) g, PWMT of tumor mice decreased to ( 1.07 ± 0. 30) g (P < 0. 05 ). At day 10, PWTL shortened to ( 12.60 ± 1.69 ) s (P < 0. 05 ) compared with sham mice ( 17.70 ± 1.54 ) s. And the pain behaviors of tumor mice were aggravated along with the development of cancer pain. (2) At day 7 after the operation, compared with tumor + vehicle group ( 1. 07 ± 0.39 ) g, PWMT of tumor + thalidomide group increased to ( 1. 53 ± 0. 39 ) g (P <0.05). At day 10, PWTL extended to ( 16.48 ± 1.13 ) s compared with sham mice ( 12.64 ± 1. 56) s (P <0. 05 ). Conclusion Intraperitoneal injection of thalidomide can efficiently relieve mechanical hyperalgia and thermal hyperalgia in a mouse model of bone cancer pain.

Objective To definite the interactions between the human gastric carcinoma cell and the human vascular endothelial cell during the establishment and maintenance of the tumor vascular system and the tumor hematogenous metastasis.Methods We prepared the conditioned mediums of each cell so as to study the effect of the conditioned medium on itself or others by MTT colorimetry. The comprehensive effect of interactions between two cells was determined by stratified transfilter co-culture or direct contact co-culture.Results The conditioned medium of human gastric carcinoma cell can stimulate the proliferation of the human vascular endothelial cell, but the CM of HVEC can inhibit the growth of HGCC. Both kinds of cells can inhibit the growth of itself. The ultimate comprehensive effect of the interactions between two kinds of cells was increase of total cell numbers.Conclusion There exist the complicated interactions between the human gastric carcinoma cell and the human vascular endothelial cell during the tumor angiogenesis and the tumor hematogenous metastasis. The ultimate comprehensive effect of the interactions is increase of total cells numbers and tumor volume.

Objective To analyze influential factors of precise intake and output record for patients with rheumatic heart disease so as to facilitate nurses to implement appropriate nursing intervention on them.Methods 60 patients with rheumatic heart diseases were randomly selected; influential factors of their precise intake and output record were analyzed; the effects of nursing intervention on them were compared in a self-contrast way. Results Influential factors of precise intake and output record for patients with rheumatic heart disease included patients themselves, nursing care education and propaganda not being in place, and impreciseness of measuring tools. Nursing intervention could control and reduce occurrence of postoperative complications, and shorten hospital stay. Conclusions It' s very important to strictly control the balance of intake and output for patients with rheumatic heart disease, which is one of the symbols for evaluating the quality of basic nursing care.

OBJECTIVETo investigate osthole effect on femoral tissue resorption activity of rat in vitro.
METHODSSix SD rats weighted (80 ± 5) g were used to isolate and culture femoral tissue (diaphyses and metaphysis) in vitro. The cultured tissue were devided into control group, estradiol group and osthole group. The femoral tissue was treated with final concentration of 1 x 10(-5) mol/L osthole and 1 x 10(-8) mol/L estradiol culture in vitro at 48 hours after cultured. Tartrate-resistant acid phosphatase (StrACP) activity, glucose and Lactic acid content, StrACP, MCSF (Macrophage colony stimulating factor) and CTSK (Cathepsin K) mRNA was detected by Real-Time RT-PCR were detected.
RESULTSConcetration of Alkaline phosphatase activity were 2226 and 2498 in 1 x 10(-5) mol/L osthole and 1 x 10(-8) mol/L estradiol respectively. As compared with control group, the activity of StrACP of 1 x 10(-5) mol/L osthole and 1 x 10(-8) mol/L estradiol were inhibited at 6, 9, 12 days (P < 0.05); under treatment of in l x 10(-5) mol/L osthole, the content of Lactic acid were increased and the content of glucose were decreased at 3, 6, 9 days (P < 0.05); StrACP, MCSF and CTSK mRNA expression level were inhibited at 6, 9 days (P < 0.05).
CONCLUSIONOsthole can inhibit bone resorption and raise the level of nutrition metabolism of femurs tissue.

Objective To sequence and analyze the VP1 region of isolated enterovirus from different sources in Beijing,2006-2008.Methods 9 EV71 were selected from the isolates identified through the specimen of human hand foot mouth disease (HFMD),acute flaccid paralysis (AFP) and healthy children in Beijing,2006-2008.Reverse transcription-polymerase chain reaction (RT-PCR) method was used to amplify and sequence the whole VP1 gene of enterovirus.Phylogenetic tree was constructed,with the means of nucleotide homology and distance between/within groups analyzed.Results The 9 selected strains were clustered with C4 subgenotype reference strains in Phylogenetic tree and showed high nucleotide acid identity (92.1%-93.9% ) in nucleotide homology analysis,and had higher homology than C1,C2,C3 subgenotype reference strains (88.8%-89.5%,89.4%-90.0% and 88.4%-89.3%,respectively).High homologous (95.9%-100.0%) was noticed between the isolated stains from three different sources,but low homologous (93.3 %-93.9%,92.1%-92.9%,respectively) showed between the isolated stains and C4 reference strains isolated in 1998.There appeared larger variations between groups in C4 subgenotype when analyzing the distance between groups means,especially between the reference strains and isolated strains (D=0.052-0.071).Conclusion The EV71 isolated in Beijing,from 2006 to 2008 also appeared to be C4 subgenotype and there was no significant difference found in the whole sequence ofVP1 gene of the strains isolated from different regions,sources,or under different diseases occurred in the same period.There were more nucleotide variations and more chances for the presence of new subgenotype,suggesting that it is necessary to strengthen the surveillance program on EV71 isolates.

Objective To identify the etiology of 8 human hand-foot-mouth disease(HFMD)outbreaks in Beijing,during May to July 2007.Methods Reverse transcription-polymerase chain reaction(RT-PCR) method was used to directly type the specimens including fluid from the herpes and throat swabs from the HFMD patients.Using RD cell lines,the collected stool specimens were cultured followed by typing.Partial VP1 region of selected EV positive specimens and cultures were sequenced and both nucleic acid sequence and predicted amino acid sequence were analyzed.Results The two HFMD outhreaks in Daxing region in Beijing in 2007 were caused by enterovirus 71 type(EV71),and the others were caused by Coxsackie virus A16(Cox A16).Two EV71 strains caused epidemics in Daxing region in 2007 belonged to C4 subgenotype but on different branches in VP1 gene phylogenefic tree.The differences on nucleic acid sequence and amino acid sequence were 3.7% and 0.8% between the two EV71 stains.respectively.The Cox A16 strain in Shunyi region and the other strains were on different branches in phylogenetic tree,and the difference on nucleic acid and amino acid sequence were 3.7% and 0% respectively between the two Cox A16 shams.Conclusion The HFMD outbreaks occurred in Beijing in 2007 were caused mainly by EV71 and Cox A16, and there were two individual epidemic virus strains.Cox A16 seemed to spread more widely than EV71 in Beiiing,2007.
