Objective To learn the current status of job burnout and influencing factors for nurses from infectious disease hospital.Methods The Chinese version MBI -HSS was used to survey 218 nurses from infectious disease hospital,and linear regression was used to analyze the influencing facters of job burnout.Results A total of 210 questionairs were cocleted.The incidence of severe occupational job burnout was 22.38%,and the score of emotional exhaustion (EE), depersonalization (DP),personal accomplishment (PA)was(22.82 ±9.98),(6.48 ±5.20),and (35.20 ±8.82), respectively.Regression analysis demonstrated that the main influencing factors were entering the isolation ward, opportunity for infectious diseases ,disinfection damage,fear of occupational exposure and concern on family infection(P <0.05).Conclusion The status of job burnout of nurses in infectious disease hospital is not optimistic.There is a positive relationship with the working environment,occupational exposure.Managers need to explore an effective way to ease the job burnout of nurses,and to stabilize the nursing team.

BACKGROUNDThe relationship between inflammatory markers and the characteristics of coronary atherosclerosis plaques is uncertain. The aim of the present study was to evaluate the relationship between the characteristics of coronary atherosclerosis plaques and inflammatory markers such as high sensitivity C-reactive proteins (Hs-CRP) and interleukin-6 (IL-6).

METHODSAll patients suspected of having coronary heart disease (CHD) underwent Siemens 64-slice CT angiography (64-SCTA) to distinguish the quality of plaque of coronary artery lesions. Blood samples were taken to measure levels of serum Hs-CRP and IL-6 in different plaque groups and the control group and compared with the value of 64-SCTA for detection of coronary artery plaque.

RESULTSThe sensitivity of detecting coronary artery plaque by 64-SCTA was 87.4%, the specificity was 87.1%, the positive predictive value was 82.2%, and the negative predictive value was 91.0%. Comparing the levels of serum Hs-CRP and IL-6 among plaque groups, the mean levels of serum Hs-CRP and IL-6 in three plaque groups were significantly higher than those in the control group (P < 0.01). The mean levels of serum Hs-CRP and IL-6 in the soft plaque group and mixed plaque group were significantly higher than those in hard plaque group (P < 0.01). Plaque burden in the soft plaque group and mixed plaque group was significantly higher than in the hard plaque group (P < 0.01), but there was no statistical difference between the soft plaque group and mixed plaque group (P = 0.246). There was a negative correlation between the CT scale and Hs-CRP and IL-6 levels in the soft plaque group (r = -0.621, P < 0.01, and r = -0.593, P < 0.01 respectively). There was a positive correlation between the plaque burden and Hs-CRP and IL-6 levels in the soft plaque group (r = 0.579, P < 0.05 and r = 0.429, P < 0.05 respectively).

CONCLUSIONS64-SCTA is an effective way to distinguish the different quality of coronary atherosclerosis plaque. Serum Hs-CRP and IL-6 levels can be considered as the indexes to judge the degree of CHD and may reflect the activity of plaque in CHD patients. Thus it is important for clinical diagnosis and risk evaluation of acute coronary syndrome (ACS) patients.

OBJECTIVE: To find the mutation of disease-causing genes of sudden unexplained death syndrome (SUDS) in the young by whole exome sequencing in one case. METHODS: One SUDS case was found no obvious fatal pathological changes after conventional autopsy and pathological examination. The whole exome sequencing was performed with the Ion Torrent PGM™ System with hg19 as reference sequence for sequencing data. The functions of mutations were analyzed by PhyloP, PolyPhen2 and SIFT. A three-step bioinformatics filtering procedure was carried out to identify possible significative single nucleotide variation (SNV), which was missense mutation with allele frequency < 1% of myocardial cell. RESULTS: Four rare suspicious pathogenic SNV were identified. Combined with the analysis of conventional autopsy and pathological examination, the mutation MYOM2 (8_2054058_G/A) was assessed as high-risk deleterious mutation by PolyPhen2 and SIFT, respectively. CONCLUSION Based on the second generation sequencing technology, analysis of whole exome sequencing can be a new method for the death cause investigation of SUDS. The gene MYOM2 is a new candidate SUDS pathogenic gene for mechanism research.

OBJECTIVETo study the effects of strontium ranelate on osteoporosis induced by simulated weightlessness in male rats.

METHODSTwenty-seven male SD rats were randomly divided into 3 groups, namely the normal control group (group A) and two groups of weightlessness simulated by tail suspension (groups B and C). The rats in group C were treated with strontium ranelate, and those in the other two groups were given the same dose of normal saline for 28 consecutive days.

RESULTSThe rats in group B showed significantly lower levels of alkaline phosphatase (ALP), bone mineral density (BMD) and bone mineral content (BMC) than those in group A (P<0.05), but serum calcium and phosphonium concentrations underwent no significant changes in the 3 groups (P>0.05). In the rats of group B, the trabeculae of the femur became thinner, fragile, and discontinuous with reduced quantity as compared with those in group A. The rats in group C had greater number of the trabeculae than those in group B with decreased resorption surface and more regular arrangement of the collagen fibers.

CONCLUSIONStrontium ranelate may produce beneficial effect on the bone microstructure, reduce bone loss and stimulate bone formation in male rats subjected to simulated weightlessness.

BACKGROUNDIn bone marrow transplant patients, the microenvironment in bone marrow is damaged after chemotherapy or radiotherapy. Subsequent to allogenic hematopoietic stem cell transplantation in patients with clinically successful engraftments, the source of mesenchymal stem cells (MSCs) remains controversial. To further verify the stimulatory effect of the simultaneous transplantation of cells from second donors on engraftment success for hematopoietic stem cell transplantation in support of donor MSCs engraftments, the aim of this study is to monitor the dynamics of the engraftment of bone marrow-derived MSCs in patients after transplantation with mismatched-sex hematopoietic stem and third-party cells.

METHODSIn this study, the hematopoietic stem cells from 32 clinical donors of different sexes that resulted in successful engraftments were selected for transplantation and were classified into three groups for research purposes: group A consisted of 14 cases of transplantation with bone marrow and recruited peripheral hematopoietic stem cell transplantation, group B contained 8 cases of simultaneous re-transfusion of MSCs from the second donor, and group C contained 10 cases of simultaneous re-transfusion of umbilical blood from the second donor. The bone marrow from 32 patients with successful engraftments of hematopoietic transplantation were selected and sub-cultured with MSCs. Flow cytometry (FCM) was used to measure the expression of surface antigens on MSCs. Denaturing high-performance liquid chromatography (DHPLC) in combination with polymerase chain reaction amplification of short tandem repeats (STRPCR) was used to measure the engraftment status of fifth-generation MSCs in patients. Fluorescence in situ hybridization (FISH) revealed the sex origin of the fifth-generation MSCs in 32 patients. Dynamic examinations were performed on patients receiving donor transplantations.

RESULTSThe progenies of fifth-generation MSCs were successfully cultured in 32 cases. The results of FCM demonstrated that the expression levels of CD14+ and CD45+ cells were lower than 0.04% in the fifth-generation MSCs. The analysis using DHPLC and FISH showed similar results. One patient from group B also received a temporary transplantation of MSCs from the donor. The MSCs in the remaining 31 patients all originated from the patients themselves.

CONCLUSIONSAfter transplantation, the MSCs present in patients originated from the host. In patients transplanted with MSCs from a second donor, the phenomenon of temporary chimerization of MSCs was observed.

OBJECTIVETo verify the clinical efficacy of acupuncture on motor dysfunction in ischemic stroke of subacute stage.

METHODSThe multi-central randomized controlled trial was adopted. One hundred and twenty-six cases of ischemic stroke of subacute stage were randomized into an acupuncture group (61 cases) and a conventional treatment group (65 cases). The basic treatment of western internal medicine and rehabilitation training were applied to the patients of the two groups. In the acupuncture group, acupuncture was supplemented at the body points located on the extensor of the upper limbs and the flexor of the lower limbs. In combination, scalp acupuncture was applied to NS5, MS6 and MS6 on the affected side. The treatment was given 5 times a week and totally 8 weeks were required. The follow-up observation lasted for 3 months. The scores in Fugl-Meyer scale and NIHSS scale and Barthel index were compared between the two groups before treatment, in 4 and 8 weeks of treatment and the 3-month follow-up observation after treatment separately.

RESULTSIn 4 and 8 weeks of treatment and the follow-up observation, Fugl-Meyer scale score was improved obviously in the patients of the two groups (all P<0. 01). In 8 weeks of treatment and the follow-up observation, Fugl-Meyer scale score in the acupuncture groupwas im proved much apparently as compared with that in the conventional treatment group [68. 0 (43. 0,86. 5) vs 52. 5 (30.3, 77.0), 77.0 (49.5, 89.0) vs 63. 0 (33.0, 84.0), both P<0. 05]. Except that NIHSS scale score was not reduced apparently in 4 weeks of treatment in the conventional treatment group (P>0.05), the results of NIHSS scale at the other time points were all decreased obviously as compared with those before treatment in the patients of the two groups (all P<0. 01). In 8 weeks of treatment and the follow-up observation, the results in the acupuncture group were reduced much apparently as compared with those in the conventional treatment group [5. 0 (3.0,8.0) vs 7. 0 (3.0,13.8), 4. 0 (1.5,7.0) vs 6.0 (2.0,11.7) ,both P<0. 05]. In 8 weeks of treatment and the follow-up observation, Barthel index was improved obviously as compared with that before treatment in the patients of the two groups (all P<0. 05). The improvement in the acupuncture group was much more significant as compared with the conventional treatment group [75. 0 (60. 0,87. 5) vs 65. O (36. 3, 87. 5), P<0. 051.

CONCLUSIONBased on the conventional treatment, Acupuncture achieves the satisfactory clinical efficacy on motor dysfunction in ischemic stroke of subacute stage.

OBJECTIVETo detect the variations in peripheral blood levels of autoantibodies, immunoglobulilns and complements in patients with non-lactational mastitis and investigate whether non-lactational mastitis is an autoimmune disease with immune dysfunction.

METHODSSeven-eight patients with non-lactational mastitis treated in our hospital between September 2013 and May 2015 and 88 healthy women (control) were examined for peripheral blood levels of antinuclear antibody (ANA), anti-histone antibody (AHA), immunoglobulins (IgA, IgM, and IgG) and complements (C3, C4, and total complements).

RESULTSs Of the 78 patients with non-lactational mastitis, 50 (64.10%) were positive of ANA showing mainly the granular and cytoplasmic granular fluorescence patterns, and the positivity rate was significantly higher than that in the control group (P<0.000). Twenty-eight (36.00%) of the patients were positive of AHA, a rate significantly higher than that in the control group (P<0.000). The levels of IgA, IgM, C4, and total complements levels were all significantly elevated in the patients compared with those in the control group (P<0.05).

CONCLUSIONPatients with non-lactational mastitis have abnormal changes in peripheral blood levels of immunoglobulins and complements with high positivity rates for ANA and AHA, indicating that non-lactational mastitis is an autoimmune disease with immune dysfunction.

OBJECTIVETo study the effect of polychlorinated biphenyl, Aroclor1254 on benzo (a) pyrene [B (a) P]-induced DNA damage in HepG2 cells.

METHODSHepG2 cells were pretreated with Aroclor1254 (11.5, 23 and 46 micromol/L) for 24 hours and then exposed to B (a) P (50 micromol/L). DMSO (10 ml/L) was used as solvent control. Single cell gel electrophoresis (SCGE) and high-performance liquid chromatography-electrochemical detection (HPLC-EC) assays were applied to detect DNA single-strand breaks and 8-hydroxy-2'-deoxyguanosine (8-OHdG) in HepG2 cells, respectively.

RESULTSAverage Oliver tail moment (OTM) and 8-OHdG level in HepG2 cells were significantly increased in B (a) P treated group (1.66 +/- 0.21), (23.31 +/- 6.02) 8-OHdG/10(6)dG than that in solvent control (0.79 +/- 0.15), (12.31 +/- 3.24) 8-OHdG/10(6)dG, respectively. In Aroclor 1254 treated group (11.5, 23.0, 46.0 micromol/L), average OTM were 0.88 +/- 0.20, 1.01 +/- 0.15 and 1.10 +/- 0.16, and 8-OHdG levels were (19.57 +/- 7.57), (22.80 +/- 9.16) and (31.74 +/- 9.25) 8-OHdG/10(6)dG, respectively. A concentration of 46 micromol/L Aroclor1254 caused a significant increase of 8-OHdG level as compared with the solvent control. After pretreatment of HepG2 cells with Aroclor1254 (11.5, 23.0 and 46.0 micromol/L), B (a) P induced more DNA strand breaks (OTM: 2.14 +/- 0.22, 2.43 +/- 0.32 and 2.71 +/- 0.31) and 8-OHdG [(32.50 +/- 3.81), (49.23 +/- 16.66) and (60.36 +/- 18.04) 8-OHdG/10(6)dG] in HepG2 cells than B (a) P alone.

CONCLUSIONAroclor1254 might enhance B (a) P-induced DNA damage in HepG2 cells, which should imply a synergistic effect of Aroclor1254 on the genotoxicity of B (a) P.
