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 provide an appropriate angle and depth of needle insertion in acupuncture at Zusanli (ST 36) and avoid injuring the nerve and blood vessel and exert the most effect.

METHODSEighty adult lower-limb samples were used to dissect and observe the relative layered structures and adjoining important nerves and blood vessels in needling Zusanli (ST 36) according to the national standard.

RESULTSThe needling depth from the skin to the interosseous membrane and from the skin to posterior border of tibialis posterior is (2.22 +/- 0.31) cm and (4.42 +/- 0.53) cm, respectively. There are flabellate branches of anterior tibial arteries and deep peroneal nerves around the needle in the superficial layer of interosseous membrane. The vessel and nerve bundles containing tibial nerve and posterior tibial vessels can be touched when the needle body past through tibialis posterior.

CONCLUSIONIt is recommended that ideal average depth of acupuncture is 2.22 cm and the maximum depth is 4.42 cm for oblique needling Zusanli (ST 36). When it is injected, the needle should be perpendicularly inserted or deviated slightly to the direction of tibia and paralleled to medial surface of tibia. And the safe needling depth is generally less than 5 cm. The point of the body surface between tibialis anterior and extensor digitorum longus at 3 cun below Dubi (ST 35) is also an effectively stimulating point.

OBJECTIVETo explore the role of monitoring sex chromosome chimeric status by fluorescence in situ hybridization (FISH) in the identification of leukemic extramedullary relapse and post-transplant lymphoproliferative disease (PTLD) in acute lymphocytic leukemia (ALL) after allogeneic hematopoietic stem cell transplantation (allo-HSCT).

METHODSSix ALL patients who received sex-mismatched allo-HSCT and manifested extravisceral lymphadenectasis or local lump were investigated. The sex chromosome chimeric status in tumor tissues and bone marrows (BM) were monitored by FISH, and EBV-RNA in the tumor tissues were detected by in situ hybridization (ISH).

RESULTSThe sex chromosomes in BM of all 6 patients were 100% donor-derived. Among the sex chromosome chimeric status of tumor tissues, three patients were mainly recipient-derived, and the percentage of sex chromosomes derived from recipients were 100%, 100% and 98.0%, respectively, and then they were diagnosed leukemic extramedullary relapse. The other 3 patients were donor-derived, the percentage was 98.5%, 96.0% and 91.5%, respectively, and were diagnosed PTLD. EBV-RNA and latent membrane protein (LMP-1) were positive in 2 patients with PTLD and negative in the other 4 patients. One patient with extramedullary relapse obtained partial remission, one with PTLD gained complete remission, and the others died eventually after therapy.

CONCLUSIONMonitoring the sex chromosome chimeric status by FISH is an effective method to distinguish leukemic extramedullary relapse from PTLD in ALL received sex-mismatched donor HSCT.

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.
