OBJECTIVE:To observe the clinical efficacy and safety of Shenmai injection combined with Trimetazidinee tablet in the treatment of hypothyroid heart disease. METHODS:64 patients with hypothyroid heart disease were randomly divided into control group and observation group. Patients in 2 groups were conventional treatment. Based on the treatment,control group was treated with Trimetazidine tablets 20 mg,orally,3 times a day;based on the treatment in control group,observation group was ad-ditionally treated with Shenmai injection 40 ml by intravenous infusion,once a day. The treatment course was 2 months. The clinic data was observed,including clinical efficacy,and T3,T4,TSH,LVEF,LVEDD and LVESD before and after treatment,pericar-dial effusion depth and incidence of adverse reactions. RESULTS:The total effective rate in observation group was significantly higher than control group(P<0.05). After treatment,T3 and T4 in 2 groups were significantly higher than before,TSH and LVESD were significantly lower than before(P<0.05),however,the difference was not statistically significant between 2 groups (P>0.05);LVEF in 2 groups was significantly higher than before,observation group was higher than control group,LVEDD and pericardial effusion depth were significantly lower than before,observation group was lower than control group(P<0.05). There were no obrious adverse reactions during treatment. CONCLUSIONS:Based on the conventional treatment,Shenmai injection com-bined with trimetazidinee has better efficacy than only trimetazidinee in the treatment of hypothyroid heart disease,with similar safety.

Using the latency of paw withdrawal (PWL) from a noxious thermal stimulus as a measure of hyperalgesia, the effects of i.p. injection of meptazinol and its isomers, 112824 and 112825, on carrageenan-induced thermal hyperalgesia were studied in awaked carrageenan-inflamed rats. Peripheral inflammation was induced by intraplantar (i.pl.) injection of carrageenan (2 mg/100 microl) into one hindpaw in rats. Carrageenan produced marked inflammation (edema and erythema) and thermal hyperalgesia in the injected paws, which peaked at 3 h after injection and showed little change in magnitude for another 3 h. Injection of 0.1 mg/kg meptazinol (i.p.) at 3 h after carrageenan had no effect on the PWLs of either inflamed or non-inflamed hindpaw during the next 100 min (P>0.05, n=8). At the dosage of 1 and 10 mg/kg, meptazinol produced marked anti-nociception and anti-hyperalgesia in non-inflamed and inflamed hindpaw, respectively (P<0.05, n=8-11). The prolonging effect of meptazinol on PWL in inflamed hindpaw was more potent than that in non-inflamed hindpaw. Pre-administration of 1.5 mg/kg naloxone significantly antagonized meptazinol-induced anti-nociception and anti-hyperalgesia. Intraperitoneal injection of an isomer of meptazinol, 112825 (1.5 mg/kg), but not 112824 (1 mg/kg), markedly increased the PWL of the non-inflamed hindpaw. Nevertheless, both the isomers produced similar anti-hyperalgesic effect to that of meptazinol (P<0.05, n=8), which was completely reversed by naloxone (1.5 mg/mg). The results suggest that meptazinol and its isomers have anti-nociceptive and anti-hyperalgesic properties with the former more potent. The effects are mainly mediated by mu opioid receptors. This study provides an important clue for extending clinical utilization of meptazinol and its isomers.

By using whole blood selenium, 24 hr urinary selenium and hair selenium contents as the indices of assessing human selenium status, it was found that the populations in the endemic areas of Keshan disease were practically in a selenium poor status. The selenium contents in locally grown staple grains and daily diets in the endemic areas were also lower than those in the non-endemic areas. In an area covering a cross section of Keshan disease geographic belt in our country, the hair selenium contents of agricultural populations were measured. The results indicated that all the hair selenium contents in the endemic sites were always at a lower level, whereas those in the non-endemic sites distant from the endemic areas were generally at a higher level; they decreased gradually until the endemic areas were reached; and finally, along the contiguous region of the endemic and non-endemic areas they were insignificantly different.The hair selenium contents among the agricultural populations were significantly lower than those among the non-agricultural ones in the same endemic areas. However, no regular correlation had been observed between the seasonal prevalence of Keshan disease and the variation of hair selenium contents in the same populations living in the same endemic sites.It is considered that the endemic areas of the disease seem to be a Se-deficiency belt, and Se-deficiency probably might be a pathogenic geo-gen in the prevalence of Keshan disease.

OBJECTIVETo examine the clinical features of children with acute lymphoblastic leukemia (ALL) complicated by pulmonary infection after chemotherapy.

METHODSThe clinical data of 108 ALL children (115 case-times) with post-chemotherapy pulmonary infection were retrospectively reviewed. The risk factors for pulmonary infection and the relationship between pathogens and chest CT findings were evaluated.

RESULTSThe highest incidence (77.4% ) of pulmonary infection occurred during remission induction, peaking at 31-60 days after chemotherapy. Patients with neutropenia had the highest incidence rate of pulmonary infection (67.0%). Bacteria (36%) and fungi (41%) were the two most common pathogens in the 41 patients who were etiologically suspected of or diagnosed with pulmonary infection. There was no significant difference in chest CT findings between patients with bacterial and fungal infections.

CONCLUSIONSThe children with ALL are most susceptible to pulmonary infection during remission induction, especially when they are neutropenic. Bacteria and fungi are the main pathogens of pulmonary infections in these patients. However, the changes in chest CT images are poor indicators of the nature of pulmonary infection.

OBJECTIVETo investigate the clinical features and genetic diagnostic method of cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL).

METHODSA systematic study on the clinical manifestations, neuroimaging characteristics, therapeutic measures and molecular genetics was performed. An investigation on the onset and hereditary pattern of the family was also done.

RESULTSThe main clinical features including poor memory and history of stroke were found. And no risk factors of hypertension and arteriosclerosis were found. A positive family history was confirmed. Neuroimaging examination showed multiinfarct lesions and leukoencephalopathy. All these features are in conformity with those of CADASIL. A mutation in the third and fourth exon of the NOTCH3 gene was identified in the 10 cases of 4 generations. The clinical or subclinical onset in the 10 cases was consistent with classical autosomal dominant inheritance.

CONCLUSIONThe clinical and molecular genetic features of the family accord with CADASIL.

OBJECTIVETo study the inhibitive effects of gastric cancer cell-dendritic cell fusion vaccine on tumor cells of proliferation cycle.

METHODSPeripheral blood mononuclear cells were separated from gastric cancer patients and co-cultured with granulocyte macrophage colony stimulating factors(GM-CSF), interleukin-4(IL-4) and tumor necrosis factor-alpha(TNF-alpha) to generate mature dendritic cells. The dendritic cells and SGC7901 cells were fused by polyethylene glycol, and the pure fusion cells were screened out by selective culture systems. The inhibitive effects of gastric cancer cell-dendritic cell fusion vaccines on tumor cell proliferation cycle in vivo and in vitro were detected by flow cytometry.

RESULTSTreated with the fusion vaccine in vitro, the percentages of G(0)/G(1), S and G(2)/M cells of tumor cells were (76.77+/- 4.38)%, (16.50+/- 2.90)% and (6.73+/- 1.59)% respectively. There were significant differences in the percentages of different cell cycle tumor cells between the tumor cells treated with the fusion vaccine and those co-cultured with dendritic cell or T cells alone(P< 0.01). The proliferative index of the tumor cells treated with the fusion vaccine was 23.34+/- 3.51, significantly lower than those co-cultured with dendritic cell and controls (P< 0.05).

CONCLUSIONSFusion vaccines can affect cell cycle of the tumor cells, thus inhibit tumor cell proliferation and growth.
