ObjectiveTo assess the degree of pain in elderly patients with mechanical ventilation in ICU using critical-care pain observation tool(CPOT) and to choose the correct sedative and analgesic method.Methods 110 elderly patients in ICU after neurosurgery were divided into three assessment stages,every stage had two record points and total six points (T1-T6):the first stage (intubation and unconsciousness,T1-T2),the second stage (intubation and consciousness,T3T4 ) and the third stage(extubation and consciousness,T5-T6 ).Among them T1,T3and T5were nonnocuity assessment points of every stage,while T2,T4 and T6 were nocuity assessment points of every stage.The assessment time was one minute at every point.After recorded at every point in second and third stages,patients were asked to use the pain intensity descriptive scale (PIDS) themselves.CPOT,heart rate and mean arterial pressure (MAP) from T1 to T6 were recorded as well as PIDS from T3 to T6 in second and third stages.Results In the three stages,CPOT〔(26.8 vs.0.54,3.36 vs.1.20,2.78 vs.0.68) scores〕,HR〔(95 vs.85,94 vs.82,94 vs.84)beat/min〕 and MAP〔(95 vs.85,95 vs.87,94 vs.87)mm Hg〕 at T2,T4and T6 were higher than T1 (t=-42.89,-55.95,-55.38),T3 (t =- 5.52,- 11.33,- 11.78) and T5 ( t =- 5.54,- 9.95,- 11.33 ) ( P＜ 0.05 ).The PIDS at T4 and T6were higher than at T3and T5in the second and third stages 〔(2.52 vs.1.69,2.12 vs.1.44)scores〕 (P＜0.05).The correlation coefficient between CPOT and PIDS at T3 and T4 in the second stage were 0.49 and 0.58,respectively (P＜0.05),and between CPOT and PIDS at T5 and T6 were 0.52 and 0.59 in the third stage,respectively (P ＜ 0.05),and they both reached moderate correlation.ConclusionsCPOT may be an effective way to assess the degree of pain in elderly patients with mechanical ventilation at present.

Objective To study the effect of candesartan (Can) on the LPS‐induced proinflammatory cytokines release in VSMCs ,and to explore the role of TLR4‐mediated signaling pathway in this process .Methods Rat VSMCs were primarily cul‐tured ,and the effect of different concentrations of Can on VSMCs activity was observed by M TT assay .The cells were divided into 5 groups :A(control) ,B(LPS intervention) ,C(LPS + 10 - 7 mol/L Can) ,D(LPS + 10 - 7 mol/L Can ) and E (LPS + Can 10 - 5 mol/L Can) .mRNA and protein levels of Toll‐like receptor‐4(TLR4) ,myeloid differentiation primary response gene 88(Myd88)and nu‐clear factor‐κB(NF‐κB) nuclear translocation were determined by real‐time PCR and Western blot ,respectively ;IL‐1β and TNF‐αconcentration were detected by ELISA .The production of intercellular reactive oxygen species(iROS) was measured by the DCFH‐DA assay .Pretreating VSMCs with the inhibitors against TLR4 ,NADPH oxidase ,and NF‐κB ,or a combination with candesartan and these inhibitors ,and then the expression of IL‐1β and TNF‐α was measured by ELISA .Results Can in the concentration range of 10 - 8 - 10 - 3 mol/L had no significant effect onVSMCs activity .Compared with th control group ,Can could effectively inhibit LPS‐induced VSMCs ,IL‐1β and TNF‐α release ,decreased the mRNA and protein expression of TLR4 ,Myd88 ,reduced the produc‐tion of iROS ,inhibited the NF‐κB(p65) nuclear translocation with a concentration‐dependent manner(P< 0 .05) .Anti‐TLR4 anti‐body ,DPI ,and PDTC all inhibited LPS‐induced inflammatory cytokines release in VSMCs ,and the combination of Can and these blockers showed stronger anti‐inflammatory effect .Conclusion Can can decrease the releaseof inflammatory cytokines IL‐1β and TNF‐α in VSMCs stimulated by LPS ,which is realized by inhibiting the signaling pathway of TLR4/Myd88‐iROS‐NF‐κB .

Objective To investigate the expression and distribution of STAT3 in the retina during the early development of postnatal hamster. Methods Immunocytochemical method and Western blot analysis were used. Results The expression of STAT3 was found in all layers of the retina in all newborn hamsters,most pronounced in the ganglion cell layer(GCL),the inner plexiform layer(IPL)and the inner area of neuroblastic layer(NBL).With the development,the STAT3 immunoreactivity was gradually restricted in the cytoplasm and the nucleus of the retinal ganglion cells.The result of the Western blot showed that the STAT3 was highly expressed in the first week of postnatal development and then reduced gradually till the lowest point in the adulthood.Conclusion The expression of STAT3 protein may be closely related to the early development of the retina in the postnatal hamster.

This study analyzed the current clinical terminology standardization, systematization research status of traditional Chinese medicine(TCM). The previous version of the TCM clinical term system had some problems including imperfect classification structure, unclear relationship between concepts and so on, which made the TCM clinical terminology system(TCMCTS) difficult to support the clinical practice of TCM. The suggestions for system improvement were using ontology method to build TCMCTS concept model bases on the previous researches and data extracted from TCM clinical electronic medical record, and top-level-ontology accordance with ISO standards. The study also tried to summarize the ‘semantic network between classes’ through semantic relationships.

[Objective]To investigate the feasibility of screening for velamentous umbilical cord insertion in early pregnancy by ultrasound.[Methods]A total of 2,796 cases of pregnant women,2 998 cases of fetuses that underwent prenatal ultrasound screening in the early and middle stage pregnancy and delivered in Dalian Women and Children Healthcare Center were included. The results of ultrasound screening of umbilical cord insertion during early pregnancy(11~13+6 w)were divided into three groups. GroupⅠ:it is clear that the placenta of the umbilical cord is located in the fetal membranes ,and then along with the fetal membranes for a long distance,and then enter the placenta. GroupⅡ:The placenta of the umbilical cord is located at the edge of the placenta,and then insert point is not distinguished between the placenta and fetal membranes. Group Ⅲ:It is clearly shows that the umbilical cord inserted into the placenta.[Results]1. The display rate of the umbilical cord in early and mid pregnancy ultrasound examinationearly pregnancyan examination showed that the rate of 99.23%(2 975/2 998). The single child display rate of 99.77%(2 590/2 596),twindisplay rate of 95.96%(380/396),three fetal the rate of 83.33%(5/6).In the second trimester of pregnancy(22~26 w)and examination showed that the rate of 86.99%(2 608/2 998). The single child display rate of 90.99%(2 362/2 596),twin display rate of 61.61%(244/396),three fetal the rate of 33.33%(2/6). 2. The results of early pregnancy,pregnancy,the examination of after birth Regard?ing to early pregnancy,28 cases were included in GroupⅠ,42 cases in GroupⅡand 2928 cases in GroupⅢ. Regarding to second pregnancy,37 cases were evaluated as velamentous umbilical cord insertion,30 cases were evaluated as battledore placenta and 2931 cases were evaluated as normal placenta. The results of postnatal examination were as follows:36 cases were identified as velamentous umbilical cord insertion,30 cases were evaluated as battledore placenta and 2932 cases were evaluated as normal placenta. 3. Comparison of 3 groups,early pregnancy examination results and pregnancy and after the birth. In early pregnancy,28 cases of GroupⅠwere diagnosed as velamentous umbilical cord insertion in the examination during the second trimester of pregnancy and after delivery. In the 42 cases of early pregnancy in Group Ⅱ,7 cases were diagnosed as velamentous umbilical cord insertion ,22 cases were diagnosed as battledore placenta and 13 cases were normal placenta. After birth ,6 cases were diagnosed as diagnosed as velamentous umbilical cord insertion ,23 cases were battledore placenta and 13 cases were normal placenta. In the 2928 cases of early pregnancy of Group Ⅲ,2 cases were diagnosed as diagnosed as velamentous umbilical cord insertion ,8 cases were battledore placenta and 2918 cases were normal placenta. After birth ,2 cases were diagnosed as diagnosed as velamentous umbilical cord insertion,7 cases were battledore placenta and 2919 cases were normal placenta.The diagnostic accuracy of early pregnancy was 98.29%.[Conclusion]Application of HD-Flow blood flow pattern in early pregnancy can make a diagnosis of some of the sail-shaped placenta.

Objective To study the expression and distribution of protein STAT3 in the retina after optic nerve transection. Methods Immunocytochemistry, Western blot and computer image analysis techniques were used. Results After optic nerve transection, STAT3 levels in the retina was highly up-regulated, the peak of which appeared at day 1 postaxotomy, then decreased gradually to the normal level 5 days later. More translocations of STAT3 to the nucleus were seen.Conclusion JAK-STAT signal transduction pathway was involved in the pathological processes in the retinal after transection of the optic nerve.

To investigate various microRNAs (miRNAs) expression levels in cancer associated fibroblasts (CAFs) of gastric cancer,and to explore the effects of miRNA214 in CAFs on the invasion and migration of gastric cancer cells.Methods The primary CAFs were isolated from human gastric tumor tissues,while the normal fibroblasts (NFs) were from adjacent normal gastric mucosa tissues.Real-time quantitative PCR (RT-PCR) was performed to detect the expression level of miRNAs in CAFs and NFs.The interaction model in vitro between CAFs and MGC-803 (a gastric cancer cell line) was established by Transwell chamber,and then the effects of miRNA-214 in CAFs on MGC-803 invasion and migration were analyzed.Results It was found that the expression level of 18kinds of miRNAs in CAFs was different.Moreover,the expression level of miRNA-214 in CAFs was most observably decreased compared with NFs.Further studies indicated that over-expression of miRNA-214 in CAFs could markedly inhibit the migration and invasion ability of gastric cancer cells in vitro.Conclusion The expression of miRNAs was different between CAFs and NFs,and the miRNA-214 expression in CAFs is markedly reduced compared with NFs.The over-expression of miRNA-214in CAFs could significantly inhibit the migration and invasion ability of gastric cancer cells.Therefore,miRNA-214 in CAFs might act as a tumor suppressor in gastric cancer progression.
