Objective To investigate the effect of early systemic nursing intervention applied by ward nurse on constipation among patients with depression. Methods A total of 144 participants were divided into the intervention group (72 cases) andthe control group (72 cases) by random number table. Except for a period of 4 weeks routine nursing and 4 weeks follow-up observation which were applied for control subjects, systemic nursing interventions werealso conducted inintervention patients. The incidence of constipation and constipation symptom scoreswere measured at the ends of the 4th and 8th week of treatment. Results The incidences of constipation and constipation symptom scores of the 4th and 8th weekend in the intervention group were 17.6% (12/68), 6.59 ± 4.08, 23.5% (16/68) and 6.81 ± 3.99 respectively. While in the control group they were 34.9%(22/63), 8.84 ± 4.45, 44.4%(28/63) and 10.52 ± 3.86 respectively. These differences between two groups at the 4th and 8th weekend were all significant (χ2=5.077, t=3.023, P < 0.05 and χ2=6.413, t=5.411, P < 0.05, respectively). Compared with the 4th weekend, in the 8th weekend, constipation rate and scores of constipation symptom were increased in thecontrol group (P < 0.05), but not in theintervention group (t=-1.965, P > 0.05). Conclusions In patients with depression, early systemic nursing intervention can effectively ameliorate the constipation caused by amitriptyline.

Between May 2009 and February 2012,60 patients scheduled for laparoscopic appendectomy were randomly assigned to receive either transumbilical single-port laparoscopic appendectomy (TUSPLA) or three-port laparoscopic appendectomy (TPLA).The operative duration was significantly longer in TUSPLA than TPLA cases.No statistically significant differences existed in hospital stay,visual analog scale (VAS) score,analgesia requirement or complication rate.The abdominal scar was inconspicuous for TUSPLA.It suggested that TUSPLA with conventional instrumentation is technically feasible and safe with scarless healing.

Objective To discuss some characteristics of aggressive behavior of junior middle school students addicted to violence online game.Methods From Aug.to Dec.at 2009,6000 volunteers have been investigated with the self-made violence online game survey scale and the Chen's were screen out by CIAS,and in which 71 violence game addicts,and 66 entertainment game addicts.They were divided into two groups matched as age and sex(male 55 and female 11 in every group),average age was 14.36±0.81 years old.66 no-play game students served as control group.The mean value and standard deviation of aggressive behaviors in each group were compared with one way ANOVA with SPSS12.0 version.Results There were significant different inter groups in the behavioral scores expressed in physiological attack((21.59±4.36),(18.10±6.10,(14.92±5.61)),spoken language attack((21.04±3.98),(18.36±6.26),(15.66±5.23)),angry mood((21.37±4.43),(18.72±5.90),(16.56±5.70)),hostility cognition((21.69±5.77),(20.06±7.74),(16.39±6.85))and the total score((85.56±13.71),(75.28±22.36),(63.54±20.32))(F1-4=25.07,17.35,3.25,10.40,21.81);Moat severity attack behaviors were observed in the violence online game addictive group,but less done in other two groups(t1-4=3.48,2.68,2.65,10.27,P<0.01;t 1-5=6.66,5.37,4.48,5.30,22.01,P<0.01);and secondary was found in Entertainment online game addicts(t1-5:3.18,2.69,2.16,3.66,11.74,P<0.01).Conclusion Higher attack behavior scores are found in the violence online game in junior middle students,and entertainment online game also induce attack behavior,but is not so notable.

Objective To study the function of vascular endothelial growth factor (VEGF) in type 2 diabetes model rats and its effect on focal cerebral ischemia induced by middle cerebral artery occlusion in these rats. Methods Focal cerebral ischemia was induced by middle cerebral artery occlusion for 6 hours in type 2 diabetes rats and normal control rats.Blood vessels morphology was examined by ink perfusion,infarct size was measured by TTC and expression of VEGF and CD34 were evaluated by immunohistochemistry staining. Results Ink perfusion revealed increased number of small vessels in type 2 diabetes rats. Infarct size was significantly smaller in type 2 diabetes rats ( ( 80. 07 ± 11.21 ) mm3 ) than that in normal controls ((98. 91 ± 14. 86) mm3,t = 2.48,P = 0. 0326). There were more hemorrhage lesions in the ischemic hemisphere in type 2 diabetes rats when comparing with the controls. VEGF and CD34 showed significantly higher expression in type 2 diabetes rats than in normal controls. Conclusions High expression of VEGF and CD34 are found in type 2 diabetes rats after middle cerebral artery occlusion. There is cerebrolvascular remodeling in diabetes rats. While this diabetes-induced remodeling appears to prevent infarct expansion,the changes also increase the risk of hemorrhagic transformation. The latter may result in poor prognosis.

Objective To investigate the molecular epidemiology of methicillin-resistant Staphylococcus aureus in China in 2005.Methods From January to December 2005,395 consecutive and non-repetitive isolates of methicillin-resistant Staphylococcus aureus were collected from 17 teaching hospitals in 14 cities.The genotypes of SCCmec were determined by multiplex PCR pulsed-field gel electrophoresis (PFGE)was used to type the chromosome DNA of MRSA.Muhilocus sequence typing(MLST)was used to type the housekeeping genes.Fifty-three strains were selected for MLST typing according to the antimicrobials susceptibility patterns,PFGE types,SCCmec types and the distribution of the regions.The toxin gene was detected by PCR.Results Among 395 isolates of MRSA,SCCmec Ⅲ,untypeable type and type Ⅱ accounted for 61.5%(243/395),24.3%(96/395)and 14.2%(56/395)respectively.In Shenyang,60.7%(17/28)of the isolates were SCCmec Ⅱ,which was significantly higher than other areas. Twenty-four different types and 42 subtypes were found by PFGE typing.Clone A accounted for 50.1%, existing in 13 teaching hospitals in 12 cities and clone R accounted for 23.5%,existing in 9 teaching hospitals in 8 cities.Six sequence types(ST)were found in these isolates with ST239 and ST5 accounting for 75.5% and 17.0% among these isolates,respectively.The prevalence of pvl gene was 2.5% among 395 isolates of MRSA.Conclusions The most types of SCCmec in China were Ⅲ and Ⅱ,and distribution of SCCmec types differed among regions.MRSA outbreaks caused by epidemic multiple-drug resistant clones occurred in big teaching hospitals in China.Meanwhile,the same PFGE pattern may spread among areas. Several international epidemic MRSA clones may exist in China.

Objective To investigate symptom characteristics and their their prevalence in terminally ill patients with ovarian carcinoma.Methods A retrospective study was carried out based on clinical data of 98 terminally ill patients with ovarian carcinoma who died in our hospital during January 1995 to December 2004.Fifteen most common symptoms were analyzed with a focus on the followings:symptom incidence,survival time after symptom occurrence,regularity of symptom cluster,and common causes of death.Fifteen symptoms were:pain,cachexia,pleural effusion and ascites,dyspnea,fever,intestinal obstruction,renal failure,bone marrow depression,lung infection,hemorrhage,deep venous thrombosis (DVT),intestinal or pancreatic fistula,mycotic infection,jaundice and emergency conditions.Results (1)The most prevalent symptom was pleural effusion and ascites(63%),followed by pain(60%), cachexia(59%),dyspnea(52%)and intestinal obstruction(49 %).(2)The symptom which lasted longest survival time was mycotic infection(77 days),followed by intestinal or pancreatic fistula(75 days), intestinal obstruction(67 days),pain(60 days)and eachexia(60 days).Symptoms such as bone marrow depression,renal failure,dyspnea and emergency conditions were comparatively critical associated with shorter survival times(14,13,12,7 days,respectively).(3)Terminal symptoms occurred typically in clusters,with 4.9?1.5 symptoms per case.Of 98 cases,84 cases(86%)had 4 or more symptoms,with the median survival time of 63 days from the last day of anti-cancer therapy,and a slow death process.The remaining 14 cases(14%)with 3 or fewer symptoms survived only 25 days,of which 10 cases(71%)died of emergency diseases.The survival time for two groups was significantly different(P

AIM: To investigate the influence and mechanism of blue light on the proliferation of human retinal pigment epithelial cells.METHODS: Cells were divided into two groups,including blue light group and control group.The 35W white light lamp with blue filter was used to establish damaged RPE cell model in vitro.Blue ray wavelength ranged between 470nm and 520nm.And the light intensity was about 2000Lx.After exposure to blue light,we tested the proliferation of human retinal pigment epithelial cells by CCK-8 kit.And then expression of miR-103 was measured by the real-time PCR.RESULTS: Exposure to blue light inhibited the proliferation of human retinal pigment epithelial cells and increased the expression of miR-103.Moreover,up-regulation of miR-103 inhibited the proliferation of human retinal pigment epithelial cells,and down-regulates miR-103 promoted the proliferation of human retinal pigment epithelial cells.CONCLUSION: Blue light inhibits the proliferation of human retinal pigment epithelial cells by the up-regulation of miR-103.

Aim ToinvestigatetheeffectsofCa2+/calmodulin-dependent protein kinase Ⅱ inhibitor KN-93 on calcium overload-induced heart injury.Methods Thirty-twoisolatedratheartswererandomlydivided into the control group,KN-93 control group,calcium paradox group,and calcium paradox with KN-93 treat-ment group.Left ventricular pressure were recorded, and the heart function was evaluated by the left ventric-ular end-diastolic pressure (LVEDP ) and developed pressure (LVDP).Coronary flow (CF)were collect-ed,and lactate dehydrogenase (LDH)content was de-termined.Triphenyltetrazolium chloride staining was usedtomeasuretheinfarctsize.Results Compared with the control group,KN-93 at 2. 5 μmol·L-1 had no effects on coronary flow,cardiac performance and cell death at the end of perfusion in normal rats (P>0. 05 );The hearts of calcium paradox exhibited a de-crease in LVDP and CF,meanwhile an increase in LV-EDP,LDH,and infarct size of 18 ±7. 2% (P <0. 01).2. 5 μmol·L-1 KN-93 further increased the levels of LVEDP,LDH and infarct size (P<0. 01)in Ca2+paradoxical hearts,while it provoked the decline intheCFandLVDP(P<0.01).Conclusion The data demonstrates that KN-93 aggravates heart injury in calcium paradox,it also suggests that CaMKⅡ is in-volved in the Ca2+overload-induced heart injury.

Objective]To discuss the effect of sciatic nerve injury on the expressions of tumor necrosis factor-alpha(TNF-α), interleukin-1β(IL-1β)and interleukin-10(IL-10)in anterior cingulate cortex(ACC),and further to explain their roles resided in the development of neuropathic pain.[Method]With use of the methods of behavioral test,western blot and immunohistochemistry, we examine the effects of spared sciatic nerve injury(SNI)on the expressions of TNF-α,IL-1β,and IL-10 in ACC,and observe the effect of the neutralizing antibody of TNF-α,IL-1β on the rat mechanical allodynia.[Result]In present experiment ,SNI increased the protein levels of TNF-α,IL-10,but not IL-1β in ACC. Increased TNF-α-IR and IL-10-IR in ACC is located in neurons ,but not astrocytes and microglia at 7 d following L5-VRT. Pre-treatment with anti-TNFα antibody but not anti-IL-1βantibody into ACC significantly increased the rat paw withdrawal threshold to von Frey hairs.[Conclusion]These data suggested that the increased TNF-αin ACC neurons might be responsible for the development of neuropathic pain.
