Objective To investigate the nurses' mastery of the patients' condition and effect of incident prevention after the application of risk assessment management in elderly patients in psychiatric wards.Methods 56 inpatients spanning from January to December 2010 were enrolled as the observation group and 55inpatients spanning from January to December 2009 were enrolled as the control group.The control group received routine care,while the observation group received risk assessment management based on routine care,which mainly include:doctors' assessment of the patient' s condition changes,therapies,medication and side effects,as well as nurses' weekly assessment of risks of falls,food choking and pressure sores and taking pertinent nursing measures.Nurses' mastery of the patients' condition and effect of incident prevention before and after the application of risk assessment management was compared.Results Average score of nurses'mastery of patients' condition was (77.36 ± 1.26) points in the control group and ( 85.60 ± 3.07) points.The difference was statistically significant ( t =11.690,P ＜ 0.01 ).The control group had 45 cases of incidents and the observation group had 19 cases.There was significant difference between the two groups (x2 =13.87,P ＜ 0.05).Conclusions The risk assessment management is beneficial to the nurses' mastery of the patients'condition and incident prevention,thus boost the nursing quality.

Objective To explore the pain assessment methods of severe senile dementia patients and nursing measures of reducing the pain stress. Methods 40 severe senile dementia patients were randomly divided into assessment group and control group (20 patients per group). Two groups were evaluated by Chinese version of Pain Assessment in Advanced Dementia Scale (C-PAINAD) with routine medical treatments-venipuncture, in addition, corresponding non-drug treatments was only given in assessment group Two groups were reevaluated by C-PAINAD 60 minutes later. Results All of the 40 patients had different degree pain during the routine medical treatments , there was no difference between the two groups ( P > 0. 05 ). The reevaluated scorns of assessment group were signitieanfly lower than that of control group ( P < 0. 01 ). Conclusions Pains are very common among severe senile dementia patients during the routine medical treatments and can be evaluated by C-PALNAD. Corresponding non--drug treatments could reduce the harmful effects of pain on senile dementia patients.

OBJECTIVETo explore the effective method of the prevention and treatment of procedural pain in dressing changes of burn wounds.

METHODSNinety patients of burn injury were randomized into 3 groups, 30 cases in each one. In the group A, fentanyl citrate injection was used at corresponding injury area, jiaogan (AH6a, sympathetic nerve), fei (CO14, lung), neifenmi (CO18, endocrine) on ear, 0.25 mL at each point. In the group B, fentanyl citrate injection was applied subcutaneously in the deltoid muscle, 1 mL. In the group C, 0.9% sodium chloride injection was applied subcutaneously in the deltoid muscle, 1 mL. The visual analogue scale (VAS) was used to evaluate the analgesic effect before, during and 10 min after dressing change in the patients of the three groups separately.

RESULTSIt was not different in VAS score before dressing change among the three groups (P> 0.05). Compared with that before dressing change, the pain was not significant and VAS score was not different during and after dressing change in the patients of the group A (both P>0.05), but the score in the patients of the group B and C was different significantly (all P<0.05). The VAS score during and after dressing change in the group A was lower than that in the group B and C (all P<0.05), and the score in the group B was lower than that in the group C (P<0.05).

CONCLUSIONFentanyl injection of small dose at auricular points achieves definite analgesic effect on procedural pain in dressing changes of burn wounds, superior to subcutaneous injection of fentanyl.

Objective To study a rare CT finding of pulsatile tinnitus(FT)caused by sigmoid sinus abnormalities.Methods The imaging data of PT caused by sigmoid sinus abnormalities were analyzed retrospectively in 15 patients(15 female).The median age was 45 years(24 to 63 years).The duration of persistence pulsatile tinnitus was from 0.5 year to 36.0 years(median time,2.0 years).The tinnitus was at left side in 5 patients and right side in 10 patients.Fifteen patients underwent HRCT of the temporal bone.Of them,12 patients underwent cerebral CT angiography and CT venogram(CTA/CTV),and 9 patients underwent cerebral digital subtraction angiography(DSA).Nine patients underwent transmastoid reconstruction surgery of the sigmoid sinus.Of them,the tinnitus was at left side in 2 patients and right side in 7 patients.Paired rank sum test was used to compare the cross-sectional area of the sigmoid sinus of the tinnitus side and normal side.Results On HRCT,focal bony coarse defect is shown in the anterior sigmoid wall in 11 patients and anterolateral sigmoid wall in 4 patients.On CTA/CTV,the sigmoid sinus focally protruded into the adjacent mastoid air cells and formed diverticulum in 10 patients.The pulsatile tinnitus disappeared immediately after transmastoid reconstruction surgery of the sigmoid sinus in all 9 patients.The cross-sectional area of the sigmoid sinus of the tinnitus side was 100.6(41.5-96.2)mm~2,it was 77.0(92.1-122.4)mm~2 in the nonmal side(Z=2.158,P=0.031).Conclusion Focal bony defect of the sigmoid wall with sigmoid sinus diverticula is one of the causes which lead to pulsatile tinnitus,which can be easily identified by imaging examination.

Background:Reduced expression of tripartite motif-containing 3 (TRIM3) has been reported to be involved in the pathogenesis of human glioblastoma.In our previous research,we found that TRIM3 expression was markedly reduced in human primary hepatocellular carcinoma (HCC) tissues and that low TRIM3 expression was associated with short survival of HCC patients.However,the role of TRIM3 in liver cancer remains unknown.This study aimed to investigate the function of TRIM3 in liver cancer cells.Methods:The protein levels of TRIM3 in five liver cancer cell lines (SK-Hep1,Hep3B,Huh7,HepG2,Bel-7402) and one normal liver cell line (L02) were detected with Western blotting.HepG2 and Bel-7402 cells with IowTRIM3 expression were infected with recombinant lentiviruses overexpressing TRIM3 (LV-TRIM3),whereas Huh7 and Hep3B cells with high TRIM3 expression were transfected with TRIM3-targeted small interfering RNA (siTRIM3).The functions of TRIM3 in the proliferation,colony formation,cell cycle,migration,invasion,and apoptosis of the above cell lines were examined.The effect of TRIM3 on tumor growth and metastases in nude mice was also investigated.Results:TRIM3 was overexpressed in HepG2 and Bel-7402 cells with LV-TRIM3 infection,which further reduced proliferation,colony formation,migration,and invasion of both cell lines.Cell cycle analysis showed thatTRIM3 overexpression induced G0/G1 phase arrest in HepG2 and Bel-7402 cells.Moreover,apoptosis was not increased in HepG2 or Bel-7402 cells overexpressing TRIM3.Contrarily,silencing TRIM3 expression in Huh7 and Hep3B cells by siTRIM3 led to significantly decreased percentages of both cells in the G0/G1 phase and promoted cell proliferation,colony formation,migration,and invasion.In vivo experiment results confirmed thatTRIM3 overexpression suppressed tumor growth and metastasis.Conclusions:TRIM3 plays a tumor-suppressing role in the regulation of liver cancer development by reducing cell proliferation through cell cycle arrest at the G0/G1 phase.

OBJECTIVETo evaluate the effect of PKC-delta inhibitor Rottlerin on human colon cancer cells and its mechanism.

METHODSHuman colon cancer cell line SW1116 cells were treated with Rottlerin. The transcriptional level of DNA methyltransferase (Dnmt)1, Dnmt3a and Dnmt3b was detected by real-time RT-PCR. Cell cycle distribution was evaluated by flow cytometry (FCM). In addition, cellular morphological changes were examined by light microscopy.

RESULTSPKC-delta inhibitor decreased the expression of Dnmt1, Dnmt3a mRNA, up-regulated APC, p21(WAF1) and p16(INK4A) mRNA. Demonstarted by flow cytometry, Rottlerin increased the percentage of cell cycle G0/G1 phase cell numbers (P = 0.02) and decreased the percentage of cell cycle G2/M phase cell numbers (P = 0.01). Remarkable changes of cellular morphology were observed under light microscope: The volume and cytoplasm of cells treated with Rottlerin were increased. The cell contour was not very clear, and mitotic figures were less frequently seen.

CONCLUSIONPKC-delta inhibitor Rottlerin inhibites cell division and proliferation of the colon cancer SW1116 cells through regulating DNA methylation and blocking the signaling pathway of mitogen-activated protein kinase (MAPK).
