A multiplex real-time PCR was developed to detect ctxA of Vibrio cholerae, gyrB and tdh of Vibrio parahaemolyticus simultaneously. The multiplex real-time PCR were evalidated by detection for the three genes in 47 toxigenic V. cholerae O1 and O139 strains (ctxA+; O1=3, O139=44), 25 non-toxigenic V. cholerae strains (ctxA-; O1=12, O139=6, non-O1 and non-O139=7), 116 V. parahaemolyticus strains with or without tdh (73 or 43) and 9 other bacteria strains. The specificity and sensitivity of the multiplex real-time PCR in detection for the ctxA and the tdh genes in the strains tested were both 100.0%, compared to the results by routine PCRs. In the detection for V. parahaemolyticus specific gyrB using the multiplex real-time PCR, all of 116 V. parahaemolyticus strains were positive, and 9 other strains and 72 V. cholerae strains were all negative. The multiplex real-time PCR is a sensitive, specific and quick assay not only for detecting virulence genes of V. cholerae and V. parahaemolyticus but also for identifying V. parahaemolyticus at species level. In addition, two real-time PCRs for detection of V. parahaemolyticus virulence genes trh1 and trh2 were also developed.

Objective To investigate the changes of IL‐1β,IL‐2 ,IL‐4 ,IL‐6 ,IL‐10 and INF‐γexpressions in bone marrow of chro‐nic myeloid leukemia(CML)patients .Methods The IL‐1β,IL‐2 ,IL‐4 ,IL‐6 ,IL‐10 and INF‐γexpression levels were detected by u‐sing flow cytometry in 30 cases of CML chronic phase(CML‐CP) ,21 cases of CML accelerated phase(CML‐AP) ,15 cases of CML blastic phase(CML‐BP) ,42 cases of CML remission after treatment and 7 cases of non‐remission .Then the detection results were compared with those in the control group .Results The expression levels of INF‐γ and IL‐2 in each CML groups were lower than those in the control group(P<0 .05) ,while the expression levels of IL‐1β,IL‐4 ,IL‐6 and IL‐10 were higher than those in the con‐trol group(P<0 .05) .With the disease condition progression ,the INF‐γand IL‐2 levels were gradually decreased ,i .e .,CML‐BPCML‐AP> CML‐CP ,the difference among groups had statistical significance (P<0 .05) .After complete remission by treatment ,the INF‐γand IL‐2 levels were risen to some extent ,but which were still lower than those in the control group(P<0 .01) ,the expression levels of IL‐1β,IL‐4 ,IL‐6 and IL‐10 were decreased to some extent ,but likewise were higher than those in CML‐CP(P< 0 .05);the levels of IL‐1β,IL‐4 ,IL‐6 ,IL‐10 ,IL‐2 and INF‐γ had no statistical difference between the non‐remission group and CML‐BP group(P>0 .05) .Conclusion The changes of serum cytokines in bone marrow microenvironment of CMLpatients have certain significance to the occurrence ,development and prognosis of CML ;the de‐tection of IL‐1β,IL‐2 ,IL‐4 ,IL‐6 ,IL‐10 and INF‐γlevels in bone marrow is hopeful to provide new ideas and theoretical basis for im‐mune therapy and prognosis judgment of CML patients .

OBJECTIVETo compare the therapeutic effects of acupuncture and Motilium on diabetic gastroparesis (DGP).

METHODSSeventy-two cases of DGP were randomly divided into a treatment group and a control group. The treatment group were treated with needling method for harmonizing spleen-stomach as main, with Quchi (LI 11), Hegu (LI 4), Zhongwan (CV 12), Zusanli (ST 36), Fenglong (ST 40), Yinlingquan (SP 9), Sanyinjiao (SP 6), Xuehai (SP 10), Diji (SP 8), and others selected, twice each day, 10 days constituting one course, with an in terval of 2 days; the control group were treated with oral administration of Motilium 10 mg, 3 times each day, 30 min before meals.

RESULTSThe total effective rate of 91.7% in the treatment group was better than 77.8% in the control group (P < 0.05).

CONCLUSIONThe therapeutic effect of the needling method for harmonizing spleen-stomach on diabetic gastroparesis is better than that of Motilium.

Objective To explore and analyze the correlation between job stress and job satisfaction among nurses in different positions at military hospital. Methods 192 nurses from different positions of military hospital were divided into three groups and investigated by the job stressor scale and job satisfaction questionnaire. Results The total scores of job stress and job satisfaction were (2.60 ± 0.21) and (3.22 ±0.38) respectively, and both of them were of moderate level. The pressure from nursing specialty was the major source of job stressor. The contract nurses tended to have more pressure and less satisfaction than the others. There was negative correlation between job pressure and job satisfaction. Significant differences existed in three groups in aspects of career development, wage and allowance, and management and policy. Conclusions Taking the effective measures to relieve the working pressure, improve the job satisfaction and keep the job stability is important to enhance the quality of nursing service.
