OBJECTIVETo study the dynamic changes in plasma D-dimer and its prognostic value in children with severe hand-foot-mouth disease (HFMD).

METHODSA total of 95 children who suffered from HFMD between May 2010 and September 2012, including 65 cases of severe HFMD (observation group) and 30 cases of non-severe HFMD (control group), were enrolled in the study. Plasma D-dimer levels of the observation group on days 1, 2, 3, 4 and 5 were compared with plasma D-dimer levels of the control group on day 1 after admission. In the observation group, plasma D-dimer levels on days 1, 2, 3, 4 and 5 were compared. The prognostic value of plasma D-dimer was analyzed using the receiver operating characteristic (ROC) curve.

RESULTSOf the 65 cases in the observation group, 15 died, and 50 survived. All the 30 cases in the control group survived. Plasma D-dimer levels in the observation group on days 1, 2, 3, 4 and 5 were significantly higher than in the control group on day 1 after admission (P<0.05). In the observation group, there were significant differences between plasma D-dimer levels on days 1, 2, 3, 4 and 5 (P<0.01), and plasma D-dimer level was the highest on day 1 after admission and second highest on the next day. Of the patients in the observation group, those who died had significantly higher plasma D-dimer levels on day 1 after admission than those who survived (P<0.05). In the observation group, plasma D-dimer levels on day 1 after onset had an area under the ROC curve of 0.877 (95% confidence interval: 0.785-0.969) and an optimal cut-off value of 582.10 μg/L (80% sensitivity and 78% specificity) for predicting mortality.

CONCLUSIONSChildren with severe HFMD have significantly increased plasma D-dimer levels, and the severer the condition, the higher the value. Plasma D-dimer levels can be used as one of the important indices for assessing the severity and prognosis of severe HFMD.

Objective To analyze the clinic-pathologic features of elderly myocardial infarction patients ( ＞ 60 years) with and without left ventricular aneurysm formation.Methods Between January 1980 and October 2009,107 myocardial infarction patients were divided into aneurysm group (n =31 ) and non-aneurysm group ( n = 76) according to autopsy results and the clinic-pathologic features of the two groups were compared.Results Previous angina pectoris history was significantly less in aneurysm group than in non-aneurysm group [ 45.2％ ( 14/31 ) vs.92.1％ ( 70/76 ),P = 0.047 ].Incidence of hypertension was significantly higher in aneurysm group than in non-aneurysm group [ 77.4％ (24/31) vs.36.8％ (28/76),P = 0.033 ].The percentage of single-vessel disease [54.8％ ( 17 /31 ) vs.23.7％(18/76),P =0.033] and the LAD disease [96.8％ (30/31) vs.51.3％ (39/76),P =0.048] were both significantly higher in aneurysm group than in non-aneurysm group.Heart failure and ventricular arrhythmias were more likely the cause of death in patients with aneurysm than patients without aneurysm [ 56.3％ (18/31) vs.19.7％ ( 15/76),P = 0.007 ].Aneurysm mostly located in left ventricular anterior wall and apex.Conclusions Our results suggest that patients with left ventricular aneurysm formation are more likely to have hypertension,single-vessel disease and LAD disease,heart failure and ventricular arrhythmias but less previous angina pectoris than patients without left ventricular aneurysm formation.The common locations of ventricular aneurvsm formation were left ventricular anterior wall and apex.

AIMTo determine the protective effect of ONO-1078, a leukotriene receptor antagonist, on focal cerebral ischemia induced by endothelin-1 in rats.

METHODSSlow microinjection of endothelin-1 (120 pmol in 6 microL, for > 6 min) into the region near the middle cerebral artery was used to induce focal cerebral ischemia. ONO-1078 (0.1 mg.kg-1) was i.p. injected 1 h before endothelin-1 injection. Neurological symptoms, brain edema, brain infarction size, and the survival neurons in cortex and striatum were observed 24 h after ischemia.

RESULTSIntracerebral microinjection of endothelin-1 induced remarkable neurological symptoms, brain infarction, brain edema, and decrease of survival neurons in the cortex and striatum. In rats pretreated with ONO-1078, endothelin-1-induced brain edema and brain infarction size were decreased. The numbers of survival neurons in striatum and cortex were increased significantly. The neurological symptoms were improved but not significantly.

CONCLUSIONONO-1078 possesses neuroprotective effect against cerebral ischemic injury induced by endothelin-1, therefore, leukotrienes may play a role in the injury of cerebral ischemia.

OBJECTIVETo study the expression of Livin, an apoptosis inhibitor gene, in prostate cancer, and to investigate its clinical and pathological implications.

METHODSThe expressions of Livin were detected in 62 cases of neoplastic prostate tissues and 10 cases of normal prostate tissues by RT-PCR and immunohistochemistry (SP method).

RESULTSThe Livin gene was highly expressed in neoplastic prostate tissues, but not in normal ones. Positive expression of Livin proteins was observed in 37 of the 62 (59.7%) tumor samples and accounted for 28.6%, 60.0% and 83.3% in the high, middle and low differentiation prostatic carcinoma groups respectively, with significant difference between the high and low groups. Livin positivity was also significantly correlated with tumor stages, increasing with tumor progression.

CONCLUSIONLivin may play an essential role in prostate carcinogenesis and serve as a marker for the prognosis of prostate cancer.

Experiments were done on urethane anesthetized adult rabbits. Long-train electrical stimulation was delivered to the Bötzinger complex (Böt.C) to observe the changes in the peak amplitude of integrated phrenic nerve activity. Then, a long-train electrical stimulation was delivered to the locus coeruleus (LC) or monosodium glutamate was microinjected into the LC . Within a certain period of time, another long-train electrical stimulation was delivered to the Böt.C to observe the responses of phrenic nerve activity. We investigated whether the LC could modulate the inspiratory inhibition induced by electrical stimulation of the Böt.C. The results are as follows: (1) Within a certain period of time after a long-train electrical stimulation applied at the LC, the inspiratory inhibition produced by electrical stimulation at the Böt.C was significantly attenuated. Comparing with the control stimulation that was only delivered at Böt.C without pre-stimulation of the LC, the inspiratory inhibition was decreased by (28.78+/-19.49)%. (2) Similarly, after chemical stimulation of the LC with microinjection of monosodium glutamate, the inspiratory inhibition produced by electrical stimulation of Böt.C was also significantly attenuated [decreased by (19.18+/-8.06)%]. The results obtained suggest that the LC plays a role in the modulation of the inspiratory inhibition of Böt.C stimulation.

OBJECTIVETo evaluate the feasibility and safety of a minilaparotomy approach for curative resection of colorectal cancer in comparison with the conventional laparotomy.

METHODSSeventy-eight patients underwent radical resection for rectal cancer with minilaparotomy during April 2001 to December 2002. The minilaparotomy involved complete resection and a skin incision 2 cm above the link line of left anterior superior iliac spine to pubic symphysis and was about 7-10 cm in length. Another 86 patients who served as control group underwent a similar resection with a conventional laparotomy during the same period.

RESULTThe minilaparotomy approach was successful in all 78 patients. The general status of patients, operative types and histopathological features of tumor were similar in the two groups (P>0.05). Operative blood loss in control group was greater (P<0.001), whereas incision length in minilaparotomy group was significantly shorter than that in conventional laparotomy (9.38 cm compared with 17.32 cm). The operative time, analgesia requirement, first passing flatus,first oral fluids and postoperative hospital stay were significantly shorter in the minilaparotomy group (P<0. 001). In an average 25.4-month follow-up, there were no tumor recurrences in the minilaparotomy group.

CONCLUSIONA minilaparotomy approach for curative resection of rectal cancer may be an ideal alternative approach to conventional laparotomy.

This study was aimed to investigate the immunological effect of modified dendritic cells (DC) which inducing cytotoxic T cells (CTL) against lymphoma cells. The DC were isolated from the lymph node and peripheral blood of patients with diffuse large B cell lymphoma (DLBCL). DC were transfected with recombinant adenovirus vector carrying human p53 gene (rAd-p53-DC). The expression of p53 gene was detected by flow cytometry. Western-blot was used to detect the expression of P53. ELISA was used to detect IL-12 level in supernatant. The mixed lymphocyte reaction (MLR) was used to detect the proliferative ability of auto-lymphocyte stimulated by DC. The lactate dehydrogenase (LDH) release test was used to determine the cytotoxicity of CTL. The results indicates that the expressions of DC surface molecule (except for CD1a) such as CD83, CD80, CD86 and HLA-DR were significantly higher in experiment group than that in control group and blank control group. The secretion of IL-12 in supernatant was higher in experiment group than that in control group. The autologous T lymphocyte proliferation and cytotoxic activity against the same kind of DLBL-cells increased in experiment group as compared with control group and blank control group (P < 0.05). The ability to stimulate T lymphocyte proliferation increased with the rising of the ratio of DC and T lymphocyte. However, there was statistically significant difference between rAd-p53-DC derived from Lymph node and peripheral blood (P < 0.05). It is concluded that rAd-p53-transfected DC can induce CTL response in vitro against lymphoma cells.
