Objective To study the expressions of α1-AT and VEGF-C in human bronchoalveolarcarcinorrm, and the relation of the expression to the patholo~cM differentiation and clinical stage. Methods All 49 Darffin embedding samples of patients with bronchoalveolar carcinoma were studied. α1-AT and VEGF-C were detected by immunohistochemical SP method.Automated image analyzer was used to quantify α1-AT and VEGF-C expressions.Results The immunohistochemical positive stainings of α1-AT and VEGF-C in brown or dark brown were located in cytopla8m.The expression levels of α1-AT and VEGF-C were not related with the gender,age,tumor position and size,and histology subtypos(P＞0.05).It Was found that the expression of α1-AT in patients with local lymph node metastasis was significantly lower than those without node metastasis(P＜0.001).It was found that the expression of VEGF-C in patients with local node metastasis significantly higher than th08e without node metastasis(P＜0.001).There Was a negative correlation between the expression level of α1-AT and the expression level of VEGF-C in bronchoalveolar carcinoma(r=-0.324,P＜0.05).Conclusion α1-AT and VEGF-C could be secreted by bronehoalveolar carcinoma.Bronehoalveolar carcinoma with lower α1-AT expression and higher VEGF-C expression is more likely to have lymph node metastasis.Lower α1-AT expression and higher VEGF-C expression can participate in the mechanism of lymph node metastasis in carcinoma together.

OBJECTIVE: To investigate the significance of human thioredoxin-2 (TRX-2) in monitoring minimal residual disease (MRD) in acute leukemia (AL). METHODS: We used real-time quantitative PCR to serially quantitize TRX-2 expression levels in the bone marrow of AL patients at diagnosis (n=68), at complete hematologic remission (CHR, n=57) and at relapse (n=25). Another 25 normal donors served as normal controls. The upper limit of the bone marrow at 91 was regarded as the reference. TRX-2 expression level at CHR with <5% blast cells in the bone marrow of relapse patients was analyzed and compared with MRD by flow cytometry. RESULTS: The TRX-2 levels between the CHR patients and newly diagnosed patients, and between the CHR patients and the relapse patients had significant difference. TRX-2 expression level of 21(21/25) relapse patients at CHR with <5% blast cells in the bone marrow was higher than the reference (>91). TRX-2 level was correlated to the expression level of MRD. CONCLUSION TRX-2 may be the marker for AL and used in MRD monitoring.

OBJECTIVE: To explore the effect of polygonum multiflorum thunb (PMT) on the expression of brain-drived neurtrophic factor (BDNF) in hippocampus CA1 in rats induced by Abeta1-40. METHODS: The rat model was established by injecting Abeta1-40 into the right dorsal hippocampus in rats, and their behavior was observed by Y-maze. The morphological changes of rat hippocampus were examined by the Nissl staining. The expression of BDNF in hippocampus CA1 neurons was also examined by immunohistochemistry and Western blot. RESULTS: After the administration of Abeta1-40, the times of rats learning how to elude electric stimulation were significantly increased, and the expression of BDNF in hippocampus CA1 were obviously reduced. The aggregation of Abeta1-40 in hippocampus and the morphological changes of CA1 hippocampus were found. After the treatment with PMT for 30 days, the times learning how to elude electric stimulation were obviously reduced, while the expression of BDNF in hippocampus CA1 was also increased. CONCLUSION PMT can reverse the down-regulation of BDNF expression in hippocampus CA1 induced by Abeta1-40.

OBJECTIVETo investigate the features of white matter myelin development in preterm infants using magnetic resonance imaging (MRI) and diffusion tensor imaging (DTI).

METHODSA total of 31 preterm infants with a gestational age of ≤32 weeks and a birth weight of <1 500 g were enrolled. According to head MRI findings, these infants were divided into preterm group with brain injury (12 infants) and preterm group without brain injury (19 infants). A total of 24 full-term infants were enrolled as control group. Head MRI and DTI were performed at a gestational age or corrected gestational age of 37-40 weeks. Fractional anisotropy (FA) and apparent diffusion coefficient (ADC) were measured for the same regions of interest in the three groups.

RESULTSThe preterm group with brain injury showed a significantly lower FA value of the posterior limb of the internal capsule than the preterm group without brain injury and full-term control group (P<0.05). The preterm groups with and without brain injury showed significantly lower FA values of frontal white matter and lenticular nucleus than the full-term control group (P<0.05). The FA value of occipital white matter showed no significant differences among the three groups (P>0.05). Compared with the full-term control group, the preterm groups with and without brain injury showed significantly higher ADC values of the posterior limb of the internal capsule, lenticular nucleus, occipital white matter, and frontal white matter (P<0.05).

CONCLUSIONSAfter brain injury, preterm infants tend to develop disorder or delay of white matter myelination in the posterior limb of the internal capsule. At a corrected full-term gestational age, the preterm infants with and without brain injury have a lower grade of maturity in periventricular white matter and grey matter than full-term infants.

Objective To examine the effects of two different cold compress modes (continuous cold compress and intermittent cold compress) on the pain and swelling among patients receiving extraction of impacted tooth of mandibular. Methods From January 2016 to August 2016, 64 cases of adult patients with impacted mandibular impacted wisdom teeth and 24 h in the outpatient department of Oral and Maxillofacial Surgery of Affiliated Stomatological Hospital of Fujian Medical University were selected. They were randomly assigned to the control group and the experimental group (32 cases in each group) by random digital table. The participants in the control group received the usual care plus intermittent cold compress. The participants in the experimental group received the usual care plus continuous cold compress. And the treatment was continued for 24 hours. Outcomes including pain and skin temperature were measured in the intervention cycle, and the swelling was measured at baseline, 6 hour, 12 hours,18 hours, and 24 hours after the intervention. All the participants were asked to have further consultation at 7th days after the operation. Results At 6 hour, 12 hours,18 hours, and 24 hours, the pain of the experimental group was lower than the control group ,and there was significant difference (F=63.665-290.872, P<0.05 ). At 12 hours,18 hours, and 24 hours after the intervention ,number of the swelling grades (0-I-Ⅱ-III) in the control group was 16, 14, 2, 0 cases, 11, 13, 8, 0 cases, 11, 12, 8, 1 cases,number of the swelling grades (0-I-Ⅱ-III) in the experimental group was 27, 5, 0, 0 cases, 26, 6, 0, 0 cases, 26, 6, 0, 0 cases, and there was significant difference (Z=-2.968,-4.017,-4.052, P<0.05). A positive correlation between swelling grade and time (M2=45.22, P<0.05). At 6 hour, 12 hours,18 hours, and 24 hours , the skin temperature of the experimental group was lower than the control group, and there was significant difference (F=1 735.106-23 993.33, P<0.05). Conclusions This study showed that the continuous cold compress was more effective in reducing the pain and swelling among the patients receiving extraction of impacted tooth of mandibular. Compared with the intermittent cold compress, it suggested that continuous cold compress can be integrated into usual care to reduce the pain and swelling among the patients receiving extraction of impacted tooth of mandibular.

OBJECTIVE: To test whether the macrophages in vein grafts may invade into the vascular wall from the adventitia apart from the lumen. METHODS: Expression of CD68 (a marker of macrophage) and CD31 (a marker of endothelial cells) in 30 vein grafts were detected by confocal immunofluroscence. Images were processed with Silicon Graphics Octane. RESULTS: In normal veins, there were a few CD68 positive cells in the adventitia, but few CD68 positive cells were found in the media and the intima. In the diseased vein, CD68 positive cells were significantly increased and present in all layers of the vascular wall, the adventitia, media and intima, extending from the adventitia to the media. There was a close relationship between the penetration of CD68 positive cells into the media from the adventitia and the angiogenesis in the media. CONCLUSION The adventitia may be an important pathway for macrophage invasion.
