RESUMEN

Acute lymphocytic leukemia (ALL) is one of the most common malignancies, especially in young people. Combination chemotherapy for ALL typically includes corticosteroids (Kantarjian et al., 2000). Hyperglycemia is a well-recognized complication of corticosteroids, and chemotherapy-induced diabetes (CID) is not uncommon (27.5%-37.0%) during the treatment of ALL (Hsu et al., 2002; Weiser et al., 2004; Alves et al., 2007). Besides the effect of corticosteroids, potential factors triggering hyperglycemia in ALL also include direct infiltration of the pancreas by leukemia cells and β cell dysfunction induced by chemotherapeutic agents such as L-asparagine (Mohn et al., 2004).

RESUMEN

Objective To evaluate the clinical value of contrast-enhanced ultrasonography (CEUS) in the diagnosis of central lung cancer with obstructive atelectasis. Methods During the period from July 2015 to October 2017, 36 central lung cancer patients with atelectasis were admitted to the First People's Hospital of Hangzhou. All the patients were diagnosed by clinical pathology, and the lesions can be demonstrated by ultrasound. CEUS was performed on all the patients. After the examination, the time from which central lung cancer began to increase, the time at which the lungs began to inflate, and the peak and disappearance time of both were analyzed, and the enhancement pattern of the lesions were observed. Results CEUS clearly distinguished central lung cancer and atelectasis in all the 36 (100%) patients. CEUS showed central lung cancer as ″slow-in and fast-out″ mode in 32 of 36 patients, and as ″fast-out and fast-in″mode in the remaining four cases. Among all patients, 18 had uniform low enhancement, 12 had non-uniform low enhancement, 4 had uniform high enhancement, and 2 had non-uniform high enhancement. The onset enhancement time was 4-10 seconds in 32 patients, and 10-18 seconds in 4 cases. The onset enhancement time of the tumor tissue was 10-15 seconds. Conclusion CEUS can distinguish tumor tissue from atelectasis and is helpful in discovering tumor tissue hidden in atelectasis.

RESUMEN

To study the effect and mechanism of Dendrobium candidum on isoproterenol-induced myocardial hypertrophy in rats, 60 healthy SD rats(30 males and 30 females) were randomly divided into 5 groups(12 in each group): normal group, model group, three D. candidum preventive administration groups(0.09, 0.18, 1.1 g·kg⁻¹). Except for the normal group, rats of other groups were injected back subcutaneously with ISO(5 mg·kg⁻¹) for 10 consecutive days. At the same time, preventive administration groups began to give different doses of the sample for 30 days and model group began to give normal saline. Left ventricular systolic pressure(LVSP) was measured in each group by common carotid artery cannulation, and the left ventricle(LW)/tibia length, heart weight index(HWI) and myocardial hydroxyproline(Hydro) content were calculated. Myocardial tissue HE staining and Masson staining were used to observe the myocardial structure and the degree of myocardial fibrosis respectively. Atrial natriuretic peptide(ANP), brain natriuretic peptide(BNP), and cardiac troponin I(cTN-I) concentration were measured by enzyme-linked immunosorbent assay(ELISA). The results showed that as compared with the normal group, the levels of ANP, BNP and cTN-I in plasma were significantly increased in ISO-induced hypertrophic rats; as compared with the model group, D. candidumcan inhibit ISO-induced ventricular pressure and ventricular hypertrophy, reduce myocardial collagen synthesis, improve myocardial fibrosis and ventricular remodeling, and significantly down-regulate ANP, BNP and cTN-I levels in plasma. This study shows that D. candidum has a protective effect on isoproterenol-induced cardiac hypertrophy.

RESUMEN

OBJECTIVE The aim of the study was to evaluated the difference and consistency in tumor size measured by sonographic and pathological examination in papillary thyroid carcinoma(PTC).METHODS A total of 114 patients with PTC, including 122 malignant nodules, was collected from Hangzhou First People's Hospital between Jun 2012 and Jun 2014. The tumor sizes were measured by preoperative sonographic and postoperative pathologic evaluation. Pearson correlation analysis, paired t-test, and Bland-Altman plot were used to evaluate the correlation and consistency in tumor size measured by the two methods.RESULTS Pearson correlation analysis showed that the largest tumor size measured by sonography were positively correlated with pathologic size (r=0.957, P=0.000). Paired t-test showed that there were statistically difference between sonographic size and pathological size (8.24±5.06) mmvs (7.79±4.75) mm,P=0.001. The absolute difference value of the largest tumor size measured by the two methods was from zero to 6.5 mm, with the average of (1.03±1.14) mm. Bland-Altman analysis showed that the limits of agreement (LoA) of difference was from -2.41 mm to 3.33 mm, with the 95% confidence interval from -2.87 mm to 3.78 mm.Within the limit of the consistency, the maximum moduli was 2.9 mm.CONCLUSION There is a significant discrepancy between the preoperative sonographic and the pathologic size of the papillary thyroid carcinoma, which should be taken into account in clinical practice.

RESUMEN

An analytical procedure for the determination of water-and methanol-extractable pentachlorophenol ( PCP) in soils using vortex assisted liquid-liquid extraction ( VALLE ) and gas chromatography ( GC ) was developed. Significant extraction parameters, such as liquid-liquid ratio and vortex speed were optimized. The recovery of PCP was the highest ( 97. 4%) at the vortex rotation speed of 2000 r/min, with good reproducbility and a small relative sdandard deviation ( RSD, 0. 5%), with regard to the volume ratio of derivatization solution to n-hexane, the recovery of PCP was 103% with an RSD of 0. 7% at 10:4. The linearity of the calibration ranged from 1. 25 μg/L to 4000 μg/L, with a correlation coefficient ( R2 ) of 0. 9999. The detection limit of the PCP in water was below 0. 2 μg/L. Compared with traditional liquid-liquid extraction ( LLE) and solid phase extraction ( SPE) , the VALLE method was more simple and more economic in terms of chemical consumption, also with a recovery of 96. 8% and a RSD of 3. 7%. Four different soils were used to check the reliability of this method. The soils were respectively extracted with water once and methanol three times. The total recoveries were 89. 5%-98. 9% and 88. 7%-98. 4% at the PCP spiking level of 1 and 10 mg/kg, respectively. It is concluded that the VALLE method satisfied the extraction and determination of water and methanol extractable PCP in soils with varying PCP polluting rates.

RESUMEN

<p><b>OBJECTIVE</b>To investigate the effects of different X-ray doses on the expression of nuclear factor-kappaB (NF-kappaB) P65 in human oral squamous cell carcinoma cell (OSCC) line and the relationship between NF-kappaB P65 and radiation-induced OSCC cell line apoptosis.</p><p><b>METHODS</b>The squamous cell carcinoma of Tca8113 cell was cultivated in the 37 degrees C, 5% CO2 incubator after recovery. The experiment samples were divided into six groups (control group, 2, 4, 6, 8, 10 Gy). After growing to logarithm period, Tca8113 cells were irradiated using above-mentioned X-ray doses. The immunocyteochemistry and Western blot were used to detect the expression of NF-kappaB P65 after irradiation in various times (1, 3, 6, 10, 24, 48 h). The apoptosis rates under different radiotherapy dose were detected by flow cytometer and TDT-mediated dUTP-biotin nick end labeling (TUNEL).</p><p><b>RESULTS</b>Compared with the control group, cytoplasm expression of P65 under different X-ray doses had statistically significant differences (P < 0.05). While the cytoplasm P65 protein expression at different time were compared each other, the 3 h group demonstrated significant difference (P < 0.05). Apoptosis rates in various groups, compared with control group, had statistically significant differences (P < 0.05). While the groups at different time points were compared each other, the apoptosis rates of 3 h group had significant differences (P < 0.05).</p><p><b>CONCLUSION</b>X-ray can activate the NF-kappaB P65 in oral squmaous cell carcinoma cell lines. The correlation between expressional quantity of P65 and radiotherapy induced apoptosis of oral squamous cell carcinoma cell lines possesses positive correlation. The activated and intranuclear P65 may have radiotherapy resistant effect.</p>

RESUMEN

<p><b>OBJECTIVE</b>To study the correlation between sperm DNA fragmentation index (DFI), age of male, various parameters of sperm, rates of fertilization, high quality embryo and pregnancy and implantation rates.</p><p><b>METHODS</b>One hundred and eleven infertile couples were selected randomly, and DFI was tested by flow cytometry for the sperm used for IVF. The patients were divided into different groups according to the DFI scores. The results of each group were analyzed.</p><p><b>RESULTS</b>The IVF normal fertilization was significantly lower in couples with sperm DFI over 10% (60.5%) than that in couples with DFI below 10% (70.1%) (P<0.05). Significantly positive correlation was found between DFI and the age of male (r=0.624, P<0.05). DFI was also significantly negatively correlated with the percentage of linearly progressive sperm (r=-0.360, P<0.05). There was no significant correlation between the rates of high quality cleaved embryos, pregnancy and implantation rate and sperm DFI.</p><p><b>CONCLUSION</b>DFI scores are increased with male's age, and it can influence the sperm motility. DFI=10% can be considered as a critical point which can be used to estimate the clinical fertility rate of IVF. But it could not provide relative information about the rates of high quality embryos and pregnancy for infertile couples undergoing IVF procedure.</p>

RESUMEN

<p><b>BACKGROUND</b>Currently it is unclear whether lipid accumulation occurs in a particular sequence and its relationship with whole body insulin resistance (IR). This study aimed to answer this question.</p><p><b>METHODS</b>Male Sprague-Dawley (SD) rats were fed on a normal or a high-fat diet for 20 weeks. Serum triglycerides (TG), serum free fatty acids (FFA), fasting plasma glucose (FPG), and liver and skeletal muscle TG were measured. The glucose infusion rate (GIR) and mRNA levels of acetyl-CoA carboxylase (ACC) and carnitine palmitoyltransferase-1 (CPT-1) in the liver and skeletal muscle were determined at different stages.</p><p><b>RESULTS</b>Compared with rats fed on the normal diet, serum FFA was not significantly increased in rats fed on the high-fat diet until 20 weeks. In contrast, liver TG was significantly increased by the high-fat diet by four weeks (20-fold; P < 0.01), and remained elevated until the end of the study. However, skeletal muscle TG was not significantly increased by the high-fat diet until 20 weeks (10.6-fold; P < 0.01), and neither was the FPG. The GIR was significantly reduced (1.6-fold; P < 0.01) by the high-fat diet after 8 weeks. The mRNA levels of ACC gradually increased over time and CPT-1 decreased over time, in both the liver and skeletal muscle in rats fed the high-fat diet.</p><p><b>CONCLUSIONS</b>Lipid accumulation in the liver occurs earlier than lipid accumulation in the skeletal muscle. Fatty liver may be one of the early markers of whole body IR. Changes in the gene expression levels of ACC and CPT-1 may have important roles in the process of IR development.</p>

RESUMEN

<p><b>OBJECTIVE</b>To examine the correlation between p65 expression and the metastasis and prognosis in tongue carcinoma.</p><p><b>METHODS</b>The immunohistochemical expression of p65 was examined in 50 cases of tongue carcinoma, and the clinical and histopathologic records were retrospectively analyzed.</p><p><b>RESULTS</b>Overexpression of p65 in cytoplasma and nucleus was found in 64% cases of tongue carcinoma. There was significant difference of p65 expression among different TNM stages, and the higher expression rate of p65 was found in higher stages. Overexpression of p65 was also related to lymph node metastasis. Significantly greater increase in expression levels of p65 was found in the metastatic cases (n = 22) compared to the nonmetastatic cases (n = 10). However, there was no significant difference of p65 expression among different histopathologic grading. The 5-year survival rate of p65 positive and negative group was 59.3% and 88.9% respectively, and there was significant difference in Kaplan-Meier survival curve (chi2 = 5.6, P < 0.05).</p><p><b>CONCLUSION</b>The results suggest that the expression of p65 was important to predict the metastasis and prognosis in tongue carcinoma.</p>

RESUMEN

The aim of this study was to explore application value of detecting platelet associated antibody and platelet membrane glycoprotein in the diagnosis and prognosis for immune thrombocytopenia. The platelet associated immunoglobulin (PAIg) and platelet membrane glycoprotein (CD41, CD61, GPIIb/IIIa) in 76 cases of immune thrombocytopenia and 30 healthy subjects were determined by FCM. The results showed that PAIg level in ITP patients included PAIgG (31.25 +/- 18.06)%, PAIgM (32.41 +/- 15.51)%, PAIgA (23.39 +/- 16.67)% which were remarkedly higher than in health control (10.48 +/- 5.05)%, (9.40 +/- 4.42)% and (7.23 +/- 3.61)% (P < 0.001). In patients with secondary immune thrombocytopenia (chronic aplastic anemia, SLE, Evans syndrome, liver cirrhosis hypersplenism, etc), PAIg level was higher than that in control group, while the platelet membrane glycoprotein in the blood of these patients was lower than that in control group. The level of PAIg decreased (P < 0.05) after treatment, but platelet membrane glycoprotein increased (P < 0.01). The result suggested that measurements for platelet membrane glycoprotein and platelet associated antibody by FCM were practical with high sensitivity, rapidity and simplicity used as a routine method in diagnosis and evaluation of the therapeutic effects in immune thrombocytopenia patients.
