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 learn the level of resilience among community health emergency staff in Zhejiang Province and its influencing factors under the epidemic situation of coronavirus disease 2019. Methods: Using stratified cluster sampling method, the community health emergency workers from six counties in Zhejiang Province were recruited in this study. A self-designed questionnaire, a scale for core emergency response capability of medical workers and 10 Items Connor-Davidson Resilience Scale ( CD-RISC-10 ) were employed. The multivariate linear regression model was used to analyze the influencing factors for resilience. Results: A total of 749 people were surveyed, with 699 valid questionnaires ( effective rate 93.32% ). Among the 699 community health emergency staffs, the total scores of resistance and core emergency response capability were 34.97±7.95 and 118.38±27.60. The multivariate linear regression analysis showed that core emergency response capability ( β＇=0.410 ), education background (diploma: β＇=0.158; bachelor: β＇=0.196), position ( top: β＇=0.083 ) and self-rated physical fitness ( not qualified: β＇=-0.152; less qualified: β＇=-0.235; generally qualified: β＇=-0.219; more qualified: β＇=-0.107 ) were the influencing factors for resilience of community health emergency staff. Conclusion The resilience of community health emergency staff in Zhejiang Province is at a medium level, and is associated with education background, physical fitnes and position.

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

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.

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.

Objective To study the accuracy,clinical value and limit in assessing the vessels surrounding pancreas involved by pancneutic carcinoma with low field MRI.Methods MRI scanning was performed in 55 patients with pancreatic carcinoma.We prospectively evaluated the MRI findings of vascular involvement by pancreatic carcinoma,and compared with the surgical results.Results Of total 55 cases,50(91%)cases were correctly diagnosed on MRI .MRI carries an accuracy of 86% for prediction of resectility,and accuracy of 93% for unresectility.Conclusion Low field MRI can accurately assess the peripancreative vessels ,but it has limited value in the patients with pancreatic carinomaⅠa orⅠb.

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.
