ObjectiveTo observe the status of social supports of the patients with advanced cancer and probe the effective nursing measures to improve the social supports of the patients.Methods"Social support rating scale"of Xiao Shui-yuan was applied to investigate the social support state of a total of 58 advanced cancer patients and 63 patients with chronic diseases.ResultsThe total score of patients with advanced cancer was(32.86±6.86),of patients with chronic diseases was(41.83±7.88).Compared with chronic disease group,the patients with advanced cancer received less social supports(P<0.05).The marriage state and economic income were significant factors to influence social support.ConclusionsThe patients with advanced cancer received less social supports than patients with chronic disease.Nursing staff should evaluate the status of social supports correctly,provide health education on patients and members in the net of social supports,make use of relative resources,then improve the social support level of the patients.

In order to provide a reference and theoretical guidance of the evaluation of electronic medical record (EMR) and establishment of evaluation system in China, we applied a bibliometric analysis to assess the application of methodologies used at home and abroad, as well as to summarize the advantages and disadvantages of them. We systematically searched international medical databases of Ovid-MEDLINE, EBSCOhost, EI, EMBASE, PubMed, IEEE, and China's medical databases of CBM and CNKI between Jan. 1997 and Dec. 2012. We also reviewed the reference lists of articles for relevant articles. We selected some qualified papers according to the pre-established inclusion and exclusion criteria, and did information extraction and analysis to the papers. Eventually, 1 736 papers were obtained from online database and other 16 articles from manual retrieval. Thirty-five articles met the inclusion and exclusion criteria and were retrieved and assessed. In the evaluation of EMR, US counted for 54.28% in the leading place, and Canada and Japan stood side by side and ranked second with 8.58%, respectively. For the application of evaluation methodology, Information System Success Model, Technology Acceptance Model (TAM), Innovation Diffusion Model and Cost-Benefit Access Model were widely applied with 25%, 20%, 12.5% and 10%, respectively. In this paper, we summarize our study on the application of methodologies of EMR evaluation, which can provide a reference to EMR evaluation in China.

Objective To explore the characteristics of auditory brainstem response(ABR) in children with otitis media with effusion(OME) before and after myringotomy with grommet insertion and the significance of ABR in diagnosing OME.Methods ABR were recorded in 50 cases(100 ears) before receiving myringotomy with grommet insertion for OME,30 cases(60 ears) underwent ABR monitoring after surgery again.For comparison,50 age-matched healthy children(100 ears) were also tested with ABR.Furthermore,30 cases were divided into two groups according to the viscidity of tympanic cavity secretion and the response threshold of wave Ⅴ were compared between the two groups.Results The response threshold of wave Ⅴand the peak latency of wave Ⅰwere normal in 13 percent of 50 cases(100 ears) before surgery.The rate of missed diagnosis was 13%.Among 50 cases,41% had normal response threshold for wave Ⅴ,52% had slight abnormal responses of thresholds of wave Ⅴ and 7% had medium response threshold of wave Ⅴ.The peak latency of wavs Ⅰwas normal in 19% OME children,but it prolonged in 72% OME children and absent in 9% OME children.The prolonged peak latencies(waves Ⅰ,Ⅲ andⅤ) and eleveted response thresholds of wave Ⅴ and shorted transmission time between waves(Ⅰ-Ⅲ andⅠ-Ⅴ) significant when compared to the control group.After surgery,the response thresholds of wave Ⅴand the peak latency of wave Ⅰwere normal in 46.7% children,the response threshold of wave Ⅴ were normal in 70.5% and slight abnormal in 29.5%.Occuring(elicit) rate of wave Ⅰwas 100% and peak latency of wave Ⅰwas normal in 50.2% chilren.The differrence of peak latencies(waves Ⅰ,Ⅲ andⅤ) and the response threshold of wave Ⅴ before surgery

Platelet play an important role in cerebral ischemial nerve injury. Aspirin (ASA) had been used to treat and prevent stroke in clinic. 30 rabbits were randomly divided into A, B and C groups. In group A ASA was given orally at a daily dosage of 15 mg/kg per rabbit for 5 days before cerebral ischemia; group B cerebral ischemia without giving ASA, and group C was normal rabbits as controls. The cerebral ischemial model was produced by occluding bilateral carotid arteries and bleeding from femoral artery. The results indicated that there was an obvious decrease of PAgT and TXA_2 and had no significance changes in free radicals increasing and Ca~(2+) rising from cerebral tissue in group A. The cerebral edema of group A was less severe than group B. It seemed that ASA had a protective effect on the nerve injury of cerebral ischemia. The derangement of ASA, platelet, free radicals and calcium ions interrelation and their significance on the nerve injury should be further studied.

Objective To observe the mitochondrial damage associated with protein-energy wasting of skeletal muscle in diabetic kidney disease (DKD) model of Goto-Kakizaki(GK) rats and evaluate the effects of low-protein diet supplemented with α-keto acids on muscle wasting.Methods Forty-five male 24-week-age GK rats were randomly divided into three groups,normal protein diet group (NPD),low-protein diet group (LPD) and LPD +or-keto group (Keto).Fifteen gender and age matched Wistar rats were served as control group (CTL).The living condition of GK rats was observed and the weight was measured once a week.Urine albumin,serum glucose,creatinine and urea nitrogen were measured at 24,32,40,48 week age.Soleus muscle was observed to calculate the muscle size and the percentage of Ⅰ and Ⅱ type muscle fiber with software after SDH and NADH staining at 48-week-age.Tissue ultrastructure was observed under the transmission electron microscopy.The activity of citrate synthase was detected by spectrophotometer.Expression of mitochondrial DNA was examined by Q-PCR.Results Compared with the CTL group,NPD,LPD and Keto groups had lower body weight,higher urine albumin,higher serum creatinine and urea nitrogen (P ＜ 0.05).The crosssectional area of muscle fibers was larger in CTL group.Compared with CTL group,the muscle fiber was partly broken,the mitochondrial morphology was obviously changed,the percentage of type Ⅱmuscle fiber was increased significantly (P ＜ 0.05),and the activity of citrate synthase and the number of mitochondrial DNA were decreased significantly in NPD,LPD and Keto groups (P ＜ 0.05).In Keto group,muscle wasting was improved compared with NPD and LPD group (P ＜ 0.05),the crosssectional area of soleus muscle increased and the percentage of type Ⅱ muscle fiber decreased,levels of urine albumin,semm creatinine and urea nitrogen decreased (P ＜ 0.05).Under transmission electron microscopy,the muscle fiber of keto group was intact and mitochondiral morphology was close to that of CTL group.The activity of citrate synthase and number of mitochondiral DNA were higher as compared to CTL group (P ＜ 0.05).There were no significant differences between NPD and LPD group.Conclusions In DKD condition,protein degradation in the skeletal muscle is accelerated,mitochondrion is swelling,the number of mitochondrial DNA is decreased and mitochondrial function is impaired.Low-protein diet supplemented with α-keto acids can improve mitochondrial damage and muscle wasting induced by DKD.

Objective To investigate the mechanism of renal damage due to rupture of atheroselerotic plaque of renal artery in apolipoprotein E (ApoE) knock-out mice. Methods The model for atherosclerotie renal artery stenosis (ARAS) was established by using ApoE knockout mice. The model mice with renal artery stenosis <50% were divided into the plaque rupture group and the non-plaque rupture group. Wild-type C57BL/6J mice were used as the control group. All the mice were raised under the same conditions. The renal arteries and kidneys were collected for the following analysis. Nuclear factor-kappa-Bp65 (NF-kBp65), intercellular adhesion molecule 1 (ICAM-1) and P-selectin (P-sel) were determined by Western blotting. The expression of interleukin 6 (IL-6) mRNA was detected by RT-PCR. Immunohistochemistry was performed by using serial sections to detect F4/80-related macrophages. Urine n-acetyl-β-d-glucosaminidase (NAG) activity was determined by direct enzyme-substrate coloration. Results In comparison with the nonplaque rupture group and the control group, the expression of NF-kBp65 protein in the blood, renal artery and kidney increased significantly in the plaque rupture group (P<0.05). The expression of F4/80, ICAM-1, P-sel, and IL-6 mRNA were increased significantly in the plaque rupture group (P<0.05), as compared with the non-plaque rupture group and the control group. The Ser and the activity of urine NAG in the plaque rupture group were higher than those in the non-plaque rapture group. The expression of NF-KBp65 protein differed insignificantly between the control group and the non-plaque rupture group (P>O.05). The group differences in the expression of F4/80, ICAM-1, P-sel, and IL-6 mRNA were similar to those in the expression of NF-KBp65 protein. The group differences in the activity of urine NAG and the Scr were similar to those in the expression of NF-kBp65 protein. Conclusion Rupture of atherosclerotic plaque of renal artery causes renal pathology change and renal function damage, which is mediated by inflammation.

Objective To identify drug resistance status of Mycobacterium tuberculosis (MTB) strains by the GenoType MTBDRplus line-probe assay (LPA),compare its performance with traditional drug susceptibility testing (DST),and to assess its predictive value for the prognosis of patients with drug resistance tuberculosis.Methods Pulmonary tuberculosis patients who visited Zhuji People's Hospital,Zhejiang Province during February 2011 and January 2012 with a positive result of sputum smear at baseline were all recruited.A total of 275 culture positive specimens were collected,then isolated and cultured for Mycobacterium tuberculosis in the laboratory.DST were performed,meanwhile,GenoType MTBDRplus were also applied to detect resistance to isoniazid (INH) and rifampin (RMP).All the tuberculosis patients who were recruited were followed,including sputum culture and chest radiography.Results There were 192 strains showing drug resistance both by DST and MTBDRplus LPA.Fourteen multidrug resistant (MDR),21 INH mono-resistant and 2 RMP mono-resistant strains were detected by DST.As for GenoType MTBDRplus LPA,MDR,INH mono-resistant and RMP mono-resistant strains were 14,18 and 2,respectively.Taken DST as the gold standard,LPA was more accurate in the detection of resistance to RMP,while it failed to detect 23.8％ (5/21) of the INH-resistant strains.We analyzed the prognosis of patients with drug resistance by GenoType MTBDRplus LPA,the rates of treatment success were 84 ％ (110/131),9/15,3/11 in patients infected with susceptible,INH mono-resistant and MDR strains,respectively.For the 2 cases of RMP mono-resistanee,one was cured and the other failed.The predictive value of molecular drug resistance test for treatment failure in INH mono-resistant patients was 40.0 ％,while that was 83.5 ％ for treatment success in INH susceptible patients.The predictive value for treatment failure in RMP mono-resistant patients was 50.0％,while that was 81.5％ for treatment success in RMP susceptible patients.The predictive value for treatment failure in MDR patients was 72.7％,while that was 81.1％ for treatment success in patients without MDR.Conclusion The GenoType MTBDRplus LPA assay is a rapid and reliable diagnostic test for resistance of MTB,which can be used to predict the prognosis of drug resistant tuberculosis in the clinical practice.

BACKGROUND:It is particularly important to establish an ideal animal model of pulmonary fibrosis to investigate the underlying pathogenesis and screen effective drugs to prevent and control pulmonary fibrosis. OBJECTIVE: To establish a modified scheme of establishing mouse models that can reflect pulmonary fibrosis formation in humans. METHODS: Fifty-six male C57BL/6 mice were randomly divided into two groups: A (a single large-dose injection) and B (multiple smal-dose injections). Mice in group A were subjected to a single intravenous injection of bleomycin 200 mg/kgviathe tail vein; and mice in group B received intravenous injections of bleomycin 50 mg/kg via the tail vein per week, totaly for 6 weeks. 

Objective To assess the incidence,risk factors and mortality of acute kidney injury(AKI)in patients with chronic myelogeneous leukemia(CML)after myeloablative allogenetic hematopoietic stem cell transplantation(HSCT). Methods Renal function in 93 CML patients undergone myeloablative allo-HSCT was retrospectively analyzed by the RIFLE criteria. Results Thirty-nine patients (41.9%) developed AKI at a median of 40 days after allo-HSCT, including 24 AKI-R patients(25.8%), 10 AKI-I patients(10.8%) and 5 AKI-F patients (5.4%). The morbidity of AKI in patients with ≥Ⅲ acute graft-versus-host disease (aGVHD) and without ＜Ⅲ GVHD was (81.82±11.63)% and (36.59±5.32)% (P=0.0037)rospectively. The morbidity of AKI in patients with increased total bilirubin and without increased total bilirubin was (72.73±13.43)% and (37.04±5.37)%(P=0.0192) respectively. ≥Ⅲ aGVHD was peor-prognostic factor of AKI and RR was 2.773 [95%CI (1.073-7.167), P=0.035]. RR of AKI-I and AKI-F in patients with ≥Ⅲ aGVHD was 6.320195%CI (1.464-27.291), P=0.013]. The mortality within 100 days after allo-HSCT of patients with AKI was significantly different as compared to patients without AKI (P=0.001). Six-mouth survival rates of different class AKI patients after myeloablative allo-HSCT were (86.96±7.02)% (AKI-R), (70.00±14.49)% (AKI-I), 0 (AKI-F) (P=0.000)respectively. Conclusions AKI is one of the main complications in CML patients after myeloablative allo-HSCT. ≥Ⅲ aGVHD and increased total bilimbin are poor-prognostic factors of AKI, and higher morbidity of AKI-I and AKI-F can be found in patients with ≥Ⅲ aGVHD. With the deteriorated AKI, 6-month survival is decreased. RIFLE criteria is sensitive to the early diagnosis of renal function. Moreover RIFLE can monitor the progression of AKI and predict the clinical outcome.

Objective To assess the clinical features of non-Hodgkin's lymphoma in cheek misdiagnosed as inflammatory myopathy.Methods Six patients presenting with unilateral swollen cheek were admitted at the Department of General Internal Medicine,Peking Union Medical College Hospital between January 2010 and December 2014.These patients were misdiagnosed as inflammatory myopathy and finally confirmed as Non-Hodgkin's lymphoma.The clinical characteristics,findings of laboratory tests and the diagnostic procedures were retrospectively analyzed.Results The median age of 6 patients (3 males and 3 females) was 30 years.The median duration from onset of unilateral swollen cheek to the final diagnosis was 13 months;the patients were referred to average 4 hospitals and experienced average 3 biopsies before admission.All patients had been treated with prednisone at a dose of 1 mg/kg or 0.5mg/kg per day.However,the symptoms relapsed in all patients after glucocorticoid tapering.No patient presented with proximal muscle weakness or myalgia.Two of 6 patients presented with unilateral forearm swollen.Creatine kinase was mildly elevated in 3 patients.Electromyographic abnormalities were seen in 4 patients.The biopsy showed muscle fiber necrosis,degeneration and a large amount of lymphocytes infiltration with or without vessel wall involvement.Erythrocyte sedimentation rate and high-sensitive C-reactive protein levels were normal.Anti-Jo-1,ANA and anti-U1RNP were all negative.EBV-DNV was significantly elevated in peripheral blood in 5 patients and it was positive in biopsy specimen in 3 patients.PET-CT scan was performed in 3 patients and suggested high metabolic activity with a SUV of 2.0-8.5 in cheek region.The biopsy specimen taken before admission did not show evidence of lymphoma.Repeated biopsies from cheek regions (3/6),lips (2/6) and forearm confirmed the final diagnosis as Non-Hodgkin's lymphoma,including 2 cases of T-cell lymphoma and 4 cases of NK/T cell lymphoma.Conclusion When patients present with unilateral swollen cheek without proximal skeletal muscle weakness or myalgia,even the pathologic evaluation implies inflammatory myopathy,non-Hodgkin's lymphoma should be considered.Repeated biopsy may be necessary to confirm the diagnosis.
