Objective To examine the relationship of coping style,psychological capital and vocational selection anxiety for female college graduates.Methods A sample of 330 female college graduates filled out measures for the simplified coping styles questionnaire (SCSQ),Psychological Capital Questionnaire (PCQ) and vocational selection anxiety Questionnaire(VSAQ).Results Correlation analysis showed that except the self-efficacy and positive coping style collected with concerns about job prospects was not significant (r=-0.08-0.05,P＞0.05),each dimensions of PCQ and SCSQ significantly correlated with the each dimensions of VSAQ (r=-0.44--0.13 or r=0.21-0.28,P＜0.01).Regression analysis showed that negative coping style,resilience,hope and positive coping style could directly predict vocational selection anxiety.Psychological capital were the mediators between positive coping styles and vocational selection anxiety.Conclusion Coping styles and psychological capital are closely related to the female college graduates' vocational selection anxiety,using appropriate coping styles and improving mental ability can effectively reduce vocational selection anxiety.

OBJECTIVETo observe the effect of hallux-trampling (HT) combined with Yaotongling suppository (YS) on the microcirculation at waist region and lower limbs in treating patients with lumbar intervertebral disc prolapse (LIDP), and to preliminarily explore its mechanism.

METHODSAdopting randomized, double-blinded medicine and single-blinded manipulation controlled method, 108 patients with LIDP of cold-accumulation and blood-stasis syndrome were assigned equally to 3 groups in random. Group A was treated with HT plus YS, Group B treated with HT plus placebo suppository, and Group C treated with YS plus mock HT. After 2-week treatment, the changes in score of symptoms and signs as well as the microcirculation at various site-points of waist and lower limbs were observed before and after treatment.

RESULTSThe total scores of symptoms and signs after treatment in Group A, B and C was 7.340 +/- 4.627, 9.543 +/- 4.745 and 10.086 +/- 4.631 respectively, which was significantly lowered as compared with those before treatment respectively (P < 0.05). Significant difference of microcirculation between pre- and post-treatment was shown at all site-points in Group A and B (P < 0.05), but only shown at the site-points of lower limbs in Group C, so significant difference (P < 0.05) was shown when compared the microcirculation in Group A or B with that in Group C (P < 0.05).

CONCLUSIONHT combined YS in treating LIDP could markedly improve the microcirculation at waist and lower limbs to correct the nutritional disturbance of nerve root, and the improvement of microcirculation is correlated with the changes of clinical symptoms and signs.

OBJECTIVETo investigate cause of chronic wounds and related status of patients so as to provide strategy for study and treatment of chronic wounds and establishment of health policy.

METHODSA total of twelve thousand one hundred and sixty-one cases hospitalized in our hospital in 2008 were enrolled in the study. A chronic wound was defined as skin tissue defect which could not heal after one month of treatment. Medical records were thus screened. Then a retrospective study was performed on patients with chronic wounds with analysis of age, gender, injury cause, therapy, and average length of hospital stay. Data were processed with chi-square test and one-way analysis of variance.

RESULTSInvestigation showed: 397 out of 12 161 cases (accounting for 3.3%) were recognized as having chronic wounds. (1) The main causes for chronic wound were burn, diabetes, and pressure ulcer, accounting for 59.9% (238/397), 15.6% (62/397), 10.8% (43/397), respectively. The other causes were operative injury, infection, varicosity, etc. There was statistical difference among the numbers of patients with chronic wounds with regard to various causes of injury (χ(2) = 136.21, P = 0.001). (2) Among patients with chronic wound, the ratio of male and female was 2.0:1.0 with mean age of (44 ± 23) years, and the highest ratio occurred in patients older than 70 years. There was significant difference in the numbers of patients with chronic wound among different age groups (χ(2) = 24.12, P = 0.025). There was statistical difference among the numbers of patients with chronic wound in different age groups with each cause of injury (with χ(2) values from 7.86 to 28.31, P values all below 0.05). (3) All patients with chronic wounds received traditional dressing. In 60.5% (240/397) and 86.4% (343/397) of patients, operative treatment or antibiotics were given. (4) The average length of hospital stay in patients with chronic wound [(38 ± 27) d] was longer as compared with that of all the inpatients in the same period [(15 ± 7) d, F = 22.82, P = 0.012]. There was obvious difference in the average length of hospital stay among patients with chronic wound caused by different reasons (F = 24.06, P = 0.036), in which burn injury resulted in the longest length of hospital stay [(47 ± 27) d].

CONCLUSIONSChronic wounds are mainly caused by diabetes and burn, and characterized by old age and longer length of hospital stay. It is necessary to strengthen translational research and related policy making, so that more rational treatment can be applied for patients with chronic wounds.

ABSTRACT:OBJECTIVE To explore the mechanism of treating Alzheimer's disease model rats by electro-acupuncture through detecting the phosphorylation of p38MAPK and tau protein in hippocampus.METHODS SD rats were randomly di-vided into control group,sham-operated group,model group and electric-acupuncture group.The model group and electric-ac-upuncture group were injected with Aβ1-40 into hippocampus.20 d later,the electric-acupuncture group had electric-acupuncture at Baihui(GV20) and Shenshu(BL23)appoints.Morris Water Maze was used to observe rates memory abilities,and western blot and immunohistochemistry were used to determine the expression of p-p38MAPK and p-tau181.RESULTS The electric-acupuncture group significantly improved learning and memory abilities(P <0.05);expression of p-p38MAPK and p-tau181 in the model group was significantly higher than the others,while significantly reduced after electric-acupuncture treatment(P <0.05).CONCLUSION Acupuncture can regulate expression of p-tau181 through p38MAPK signaling pathway and improve the learning and memory ability of AD rats.

To investigate the effect of a new reactive oxygen metabolites (ROM) scavenger as immune adjuvant in NK cell-mediated killing effect on K562 cell, IL-2 and PHA were used to activate monocyte to produce ROM, and different concentrations of tiopronin as ROM scavenger was used in the cultivated systems with different ratio of monocytes plus NK cells and K562 cells, while histamine dihydrochloride (DHT) with different concentrations was used as positive control. The reuslts indicated that after IL-2 and PHA were supplemented in the cultivated systems mixing with NK cells and K562 cells as the E/T ratio was 10/1, the ROM production increased from 33.17 +/- 25.02 U/ml to 223.59 +/- 59.41 U/ml (P < 0.05) while K562 cell inhibition rate (KIR) increased from 65.56% to 85.89% (P < 0.05). When the monocytes as the E/MO ratios of 10/2, 10/5 and 10/10 were supplemented respectively, ROM production increased correspondingly (ROM production was 389.79 +/- 43.83 U/ml, 456.74 +/- 42.77 U/ml, 601.42 +/- 21.92 U/ml, respectively), and KIR was on the other round (KIR was 82.36%, 81.36%, 48.09% respectively). Tiopronin, DHT were used in the K562 + NK + MO + IL-2/PHA cultivated systems as the E/MO ratio was 10/2, the ROM production also decreased from 389.79 +/- 43.83 U/ml to -1.20 +/- 60.70 U/ml, 50.21 +/- 22.4 U/ml (P < 0.05), respectively, however KIR increased from 82.53% to 96.09% and 94.64% either (P < 0.05). Higher concentrations of tiopronin and DHT were used, ROM production decreased accordingly. There showed a reverse correlation between ROM production and KIR (r = -0.518). When E/MO ratio was 10/5 or 10/10, tiopronin at any testing concentration and DHT at the higher testing concentration could reduce the ROM production (P < 0.05), but did not improve KIR significantly (P > 0.05). Tiopronin was as good as DHT in ameliorating KIR (P > 0.05) and better than DHT in scavenging ROM (P < 0.05). It is concluded that (1) Monocytes are the major resources of ROM, and the ROM derived from monocytes can disable NK cells in killing neoplasm cells (K562 cells); (2) A new ROM scavenger, tiopronin, can scavenge ROM effectively, and reverse the ROM induced inhibition of NK cell-mediated killing of K562 cell in a certain extent. And tiopronin is better than DHT in scavenging ROM, and as good as DHT in up-regulating KIR. The new ROM scavenger tiopronin with less side effect may take the place of DHT as adjuvant during the adoptive immuno-therapy in leukemia.

OBJECTIVETo investigate the specific antitumor immune response induced by idiotype protein (Id)-pulsed dendritic cells (DC) in vitro.

METHODSDC was generated from peripheral blood monocytes of the multiple myeloma (MM) patients using GM-CSF, IL-4, and TNF-alpha. The DCs were pulsed with idiotypic fragment, the F(ab')2 fragment of M protein from MM patient at the immature stage. The morphologic characteristics of the cells were observed with light and electron microscopes. The phenotypic features were analyzed with FACS, MTT assay was employed to evaluate the proliferation of autologous T cells and the inhibition rate of MM cells.

RESULTSDC precursors in peripheral blood could be induced to typical mature DC in medium containing GM-CSF, IL-4 and TNF-alpha. Mature DC with Id could increase the proliferation of the autologous T cells and activate naive T cells to become tumor specialized cytotoxic T lymphocytes (CTL). The CTL at different doses showed significant inhibition on or killing ability to autologous MM cells in vitro.

CONCLUSIONSIn a suitable cytokine environment, the DC precursors from peripheral blood of MM patients could be induced to functional DC, and vaccination of Id-pulsed DC could induce active antitumor immune response.
