Objective To investigate the meaning of expression of apoptosis related molecules NFKBp65 and p53 and GPX1-mRNA in patients with Keshan disease(KSD).Methods Sixteen chronic Keshan Disease patients were enrolled in KSD group according to electrocardiogram,chest X ray film and clinical examinations on 15,September in 2009,and 23 healthy people were included in control group from physical examination taken in The Second Affiliated Hospital of Xi'an Jiaotong University.Fresh blood(5 ml)was collected from antecubital vein of all subjects in the fasting state.Total mRNA and protein of blood sample were isolated using Trizol.GPX Assay Kit was used to detect GPX enzyme activity,and GPX1-mRNA expression was determined by SYBR Real-Time PCR.Meanwhile,expression of apoptosis related molecules NFKBp65 and p53 were determined by Western blot.Results GPX enzyme activity decreased significantly in KSD group[(108.61±14.10)U]compared with control group[(122.78±11.89)U,t=2.874,P<0.05],GPX1-mRNA level of KSD group(0.553±0.299)notably KSD group(0.802±0.057)compared with control group[(1.065±0.355),t=6.829,P<0.01].p53 increased in KSD group(1.604±0.191)compared with control group[(1.137±0.186),t=3.033,P<0.05].Conclusiom Decreased GPX1-mRNA expression may result in lower GPX enzyme activity of patients with KSD.Thus oxidative damage increases and cadioeyte apoptosis is activated by activating apoptosis signal pathway.

Fourier transform mid-infrared spectroscopy (FTIR) method was used to analyze the soil organic matter (SOM) composition of a black soil under different management types. Spectral subtraction method was used for eliminating the interference of soil mineral to the absorption peak. Peaks at 2920,2850,1630 and 1420 cm-1were selected as a range of organic functional groups, and relative areas of these peaks were calculated by integral method. The correlation between peak areas and the content of SOM fractions were analyzed. Positive correlations between carbon (C) in fractions representing labile SOM (water-soluble organic carbon,hot water-soluble organic carbon, free light fraction carbon, occluded light fraction carbon) and the peak area at 2920 cm-1in the bulk soil indicated that this aliphatic peak corresponded to the more labile C compounds. Negative correlations between the same fractions and the area of the predominantly aromatic peak at 1630 cm-1in the bulk soil suggested a relationship with more stable SOM compounds. The ratio of the peaks at 1630 and 2920 cm-1was positively correlated with the ratio of stable C(heavy fraction) to labile C (light fraction) and thus taken as an indicator of SOM stability. This method was convenient, low cost and less sample usage,and could be used to analyze the organic carbon composition of soils which has the same mineral composition.

OBJECTIVETo investigate the relationship between extracapsular spread (ECS) of cervical metastatic lymph node and the recurrence in patients with oral squamous cell carcinoma (OSCC).
METHODSThe medical records of 74 OSCC patients with histologically confirmed cervical lymph node metastasis were reviewed. They were divided into 2 groups, ECS positive (ECS+) and ECS negative (ECS-). The treatment results were followed up. Statistical analysis, with chi-square test, and multiple logistic regression was conducted.
RESULTSThe overall recurrence rates for pN+/ECS- and pN+/ECS+ patients were 47.6% and 75.0%, respectively, and the cervical recurrence rates for pN+/ECS- and pN+/ECS+ patients were 9.5% and 46.9%, respectively (P < 0.001). Multivariate analysis showed that ECS was one of the independent prognosis factors for cervical recurrence.
CONCLUSIONSExtracapsular spread significantly increased both overall and cervical recurrence rates, and ESC may be a prognosis factor for OSCC patients.

OBJECTIVETo investigate the changes in brain injury after the induction chemotherapy in children with acute lymphoblastic leukemia (ALL) by cranial MRI.
METHODSThe clinical data and cranial MRI results of 62 children with ALL who were hospitalized from March 2014 to June 2015 were analyzed retrospectively.
RESULTSBefore chemotherapy, MRI showed bone marrow infiltration of the skull in 33 patients (53%); the children with WBC<20×10(9)/Lhad a significantly lower incidence rate of bone marrow infiltration of the skull than those with WBC≥20×10(9)/L (16 patients/42% vs 17 patients/71%; P<0.05), and the high-risk group had a significantly higher incidence rate of bone marrow infiltration of the skull than the non-high-risk group (71% vs 44%; P<0.05). Before chemotherapy, there were 4 cases (7%) of brain atrophy, and 2 cases (3%) of abnormal signals in the sensory conduction bundle. MRI reexamination in 28 patients after 3 months of chemotherapy showed 3 new cases (11%) of brain atrophy and 1 aggravated case of brain atrophy.
CONCLUSIONSThe children with ALL have bone marrow infiltration of the skull, brain atrophy, and abnormal signals in the sensory conduction bundle before chemotherapy, especially bone marrow infiltration of the skull, and some changes in brain injury disappear after treatment.

OBJECTIVETo study the clinicopathologic and immunohistochemical features of primary superficial esophageal small cell neuroendocrine carcinoma (ESCNC).
METHODSThe clinical, pathologic and immunohistochemical features were retrospectively analyzed in 15 cases of superficial ESCNC. An immunohistochemical study for chromogranin A, neuron-specific enolase, synaptophysin, CD56, TTF-1, 34βE12, AE1/AE3, and CK10/13 was performed.
RESULTSSuperficial ESCNC accounted for 4.8%(15/312) of all cases of superficial carcinoma of the esophagus encountered during the same period. The median survival time was 19 months and the mean survival time was 23.7 months after diagnosis. The one, two and five-year survival rates were 10/15, 5/15 and 1/15, respectively. The immunophenotypic profile was as follows: neuron-specific enolase (15/15), synaptophysin (15/15), AE1/AE3 (15/15), CD56 (14/15), TTF-1 (9/15), chromogranin A (8/15), 34βE12 (1/15) and CK10/13 (0/15).
CONCLUSIONSSuperficial ESCNC is a rare and aggressive malignant tumor with poor prognosis. Surgical resection coupled with post-operative chemoradiotherapy is the mainstay of treatment. The immunohistochemical study is valuable in pathologic diagnosis and differential diagnosis.

OBJECTIVETo detect the expression of thyroid transcription factor 1 (TTF-1) and study its application in the diagnosis of lung carcinomas.
METHODSOf 134 specimens from lung lobectomy, 105 were primary lung carcinomas including 76 non-small cell carcinomas (NSCLCs), 28 small cell lung cancers (SCLCs) and 1 complex carcinoma (SCLC and SCC), and 29 were metastatic carcinomas. Expression of TTF-1 was detected by immunohistochemistry. The expression level of TTF-1 was graded as, +:6% to 25% of tumor cells positive, ++:26% to 50%, +++:51% to 75%, and ++++:> 76%.
RESULTSThe positive nuclear immunoreactivity of TTF-1 was identified in 23 of 28 SCLCs (82.1%), but none in squamous cell cancer (SCC) (P < 0.001). The positive expression rate of TTF-1 in lung adenocarcinomas (ACs) was 73.8% (31/42). There was no correlation between TTF-1 expression and ACs differentiation or ACs subtypes (P > 0.05). All but one (thyroid follicular carcinoma) metastatic ACs were TTF-1-positive. Mesenchymal component and lymphoid or inflammatory cells were consistently TTF-1-negative.
CONCLUSIONA significant difference of TTF-1 expression may assist in distinguishing SCLC from SCC, lymphoma or inflammatory lesions. Owing to its restrictive expression in lung tissue, TTF-1 might be used to differentiate primary from metastatic adenocarcinoma of the lung.

OBJECTIVETo evaluate the significance of somatic mutations of VHL gene and hypoxia-inducible factor-1alpha (HIF-1alpha) expression in primary renal clear cell carcinoma (RCC).
METHODSMutation of VHL gene and HIF-1alpha expression were detected by means of PCR, denaturing high-performance liquid chromatography (DHPLC), direct sequencing and immunohistochemistry in 32 samples from primary renal clear cell carcinoma patients.
RESULTSIn 32 RCC samples, 17 samples (53.1%) had and 32 samples of adjacent nonmalignant renal tissue had not mutations of VHL gene expression. Twelve RCC samples (70.6%) which had mutations of VHL gene expressed HIF-1alpha, and it had significant difference to 4 RCC (26.7%) samples which didn't have mutations of VHL gene (P < 0.05).
CONCLUSIONMutations of VHL gene may play a significant role in the tumorigenesis of RCC, and HIF-1alpha expression correlates with it.
