ABSTRACT

Objective To compare the values of dynamic enhanced magnetic resonance imaging(DCE-MRI),digital breast tomosynthesis(DBT),and digital mammography(DM)in the early detection and diagnosis of breast cancer.Methods We retrospectively analyzed the clinical and imaging data of 65 cases with early breast cancer confirmed by surgical pathology from June 2017 to December 2018.All patients underwent breast DCE-MRI,DM and DBT before surgery.The receiver operating characteristic(ROC)curves were drawn,with the pathological results as the gold standard,to evaluate the diagnostic performance of different examination methods.The areas under ROC curves(AUCs)were compared using test.The differences among DCE-MRI,DBT and DM in detecting early breast cancer were compared using chi-square test in terms of positive rates,accuracy,sensitivity,and specificity.Pearson correlation analysis was performed to assess the accuracy of these imaging methods in detecting the size of early breast cancer.Results The AUCs of DCE-MRI,DBT,and DM based on the BI-RADS classification for early diagnosis of breast cancer were 0.910,0.832,and 0.700,respectively(=2.132,=0.001);the sensitivity of DCE-MRI,DBT,and DM for early breast cancer was 92.3%,70.8%,and 52.5%,the specificity was 65.0%,85.0%,and 79.3%,and the accuracy was 83.1%,70.8%,and 50.8%,indicating that DCE-MRI(=15.330,=0.0001) and DBT(=5.450,=0.020) had significantly higher diagnostic accuracy than DM.The measurement results of DM,DBT,and DCE-MRI were positively correlated with the pathological measurements(=0.781,=0.847,=0.946;all <0.01). Conclusions DCE-MRI and DBT have higher positive rates and accuracies than DM in detecting early breast cancer.Medical institutions where DCE-MRI is still not available can use DBT to improve the early detection of breast cancer.

ABSTRACT

@#Objective    To compare the clinical data of pulmonary lobectomy in patients with massive hemoptysis of pulmonary tuberculosis after bronchial artery embolization in the short and long term, so as to provide a reference for clinical choices of appropriate operation time. Methods    A retrospective analysis was conducted on 33 patients with massive hemoptysis of pulmonary tuberculosis, who had received pulmonary lobectomy after bronchial artery embolization in Wuhan Pulmonary Hospital from January 2015 to November 2017, including 29 males and 4 females aged of 23-66 (52.64±9.70) years. According to the time interval between bronchial artery embolization and lobectomy, the patients were divided into a short-term group (<2 weeks, 14 patients) and a long-term group (>1 month, 19 patients). The clinical data, such as operation time, intraoperative blood loss, postoperative extubation time and serious postoperative complications, were observed in the two groups for statistical analysis. Results    The operative time (297.13±75.69 min vs. 231.32±67.57 min, P=0.013), intraoperative blood loss (685.74±325.51 mL vs. 355.83±259.11 mL, P=0.002), postoperative extubation time (14.07±5.24 d vs. 8.90±3.57 d, P=0.003) of the short-term group were all higher than those in the long-term group. Conclusion    For the patients with massive hemoptysis of pulmonary tuberculosis, who had surgical indications and no risk of early rebleeding after bronchial artery embolization, pulmonary lobectomy should be performed late until the patient's physical condition and the primary disease was stable.

ABSTRACT

The development and metastasis of uterine tumors depend highly on tumor angiogenesis. Multiphase dynamic contrast-enhanced magnetic resonance imaging can quantitatively describe the hemodynamic changes of uterine tumors based on a variety of tracer kinetic models and time-signal curves and by simulating the distribution of contrast inside and outside the blood vessels. Functional parameters can accurately and noninvasively assess tumor angiogenesis. It provides a non-invasive functional evaluation method for the differential diagnosis,staging,response evaluation,and prognostic prediction of uterine tumors.

ABSTRACT

Objective To analyze and compare the application results of glibenclamide and insulin in treating gestational diabetes mellitus (GDM). Methods The subjects of this study were selected from 68 cases of pregnant women with GDM admitted in our hospital from September 2015 to March 2017. They were randomly divided into the control group (insulin) and the observation group (glibenclamide), each with 34 cases. The clinical efficacy and adverse pregnancy outcomes were compared between the two groups. Results The fasting blood-glucose (FBG), 2 h postprandial plasma glucose (2 h PG), and glycosylated hemoglobin (HbA1c) levels of both groups after treatment decreased significantly (P<0.05), but there was no big difference in the above indexes between the two groups after treatment. The incidence of fetal macrosomia, fetal asphyxia and neonatal hypoglycemia in the observation group was 17.65%, 23.53% and 20.59% respectively, much higher than that in the control group (P<0.05). Conclusion In treating GDM, both glibenclamide and insulin are effective in enabling better blood-glucose control, but insulin has an advantage over the other in improving pregnancy outcomes. With the informed consent of some GDM patients, oral hypoglycemic agents can be used with caution.

ABSTRACT

·AIM:To study the influence factors and management of anterior chamber gas bubble during femtosecond flap creation for laser-assisted in situ keratomileusis ( LASIK) .·METHODS: Totally 9671 eyes of 4859 patients with femtosecond LASIK were included in this study. Preoperative, intraoperative and postoperative parameters of anterior chamber gas bubble patients were analyzed and compared.·RESULTS:A total of 51 cases (0. 53%) occurred anterior chamber gas bubble during femtosecond flap creation. There was no statistical difference between uncorrected visual acuity of postoperative 1mo (-0. 076 ± 0. 09 ) and preoperative best corrected visual acuity (-0. 08±0. 04; t=-0. 34,P=0. 74). And 33 eyes (65%) did not affect the pupil tracking, but there were 18 eyes ( 35%) unable to track the pupil successfully. There was no statistical difference in uncorrected visual acuity of postoperative 1mo between trace group (-0. 06 ± 0. 08 ) and no trace group(-0. 11 ± 0. 09; t = 1. 82, P = 0. 07). The highest incidence of anterior chamber gas bubble was at 9 point, followed by 3 point. There were no statistical differences in spherical equivalent refraction, corneal curvature, corneal diameter, anterior chamber volume, anterior chamber depth and intraoperative femtosecond laser energy between anterior chamber gas bubble eyes and the contralateral eyes (P>0. 05).·CONCLUSION: Anterior chamber gas bubble formation during femtosecond flap creation for LASIK is an uncommon event. It may affect the eye tracking. There is no obvious effect on early postoperative visual acuity if intraoperative disposed properly. The direct or indirect factors of anterior chamber gas bubble formation are unclear.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the efficacy of novel object recognition (NOR) test in assessment of learning and memory ability in ICR mice in different experimental conditions.</p><p><b>METHODS</b>One hundred and thirty male ICR mice were randomly divided into 10 groups: 4 groups for different inter-trial intervals (ITI: 10 min, 90 min, 4 h, 24 h), 4 groups for different object materials (wood-wood, plastic-plastic, plastic-wood, wood-plastic) and 2 groups for repeated test (measured once a day or every 3 days, totally three times in each group). The locomotor tracks in the open field were recorded. The amount of time spent exploring the novel and familiar objects, the discrimination ratio (DR) and the discrimination index (DI) were analyzed.</p><p><b>RESULTS</b>Compared with familiar object, DR and DI of novel object were both increased at ITI of 10 min and 90 min (P<0.01). Exploring time, DR and DI were greatly influenced by different object materials. DR and DI remained stable by using identical object material. NOR test could be done repeatedly in the same batch of mice.</p><p><b>CONCLUSION</b>NOR test can be used to assess the learning and memory ability in mice at shorter ITI and with identical material. It can be done repeatedly.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the feasibility of chondrogenesis in vitro with bone marrow stromal cells (BMSCs) induced by the co-cultured chondrocytes.</p><p><b>METHODS</b>The BMSCs and chondrocytes were separated from pig and cultured. The supernatant of chondrocytes was used as the inducing solution for BMSCs from the 2nd generation. 7 days later, samples were taken and underwent immunohistochemistry and RT-PCR for detection of the expression of specific type II cartilage collagen, type II collagen and aggrecan mRNA. The cultured BMSCs and chondrocytes were mixed at a ratio of 8:2 (BMSC: cartilage cell) and were inoculated into a polyglycolic acid/polylactic acid (PGA/PLA) scaffold at the final concentration of 5.0 x 10(7)/ml. The cartilage cells and BMSCs were also inoculated separately at the same concentration as the positive and negative control. Pure cartilage cells at 20% of the above mentioned concentration (1.0 x 10(7)/ml) were used as the low concentration cartilage cell control group. Samples were collected 8 weeks later. General observations, wet weight, glycosaminoglycans (GAGs) determination and histological and immunohistochemistry examinations were performed.</p><p><b>RESULTS</b>The expression of type II collagen, type II collagen and aggrecan mRNA were positive in induced BMSCs. In the co-cultured group and the positive control group, pure mature cartilage was formed after 8 weeks of culture in vitro, and the size and shape of the scaffold were maintained. The newly formed cartilage in the two groups were almost the same in appearance and histological properties. The immunohistochemistry results indicated that the cartilage cells of the two groups all expressed ample cartilage-specific type II collagen. The average wet weight and GAG content in the co-cultured group reached more than 70% of those in positive control group. Only an extremely small amount of immature cartilage tissues was formed in local regions in pure BMSC group, and the scaffold was obviously shrunk and deformed. Although the wet weight of newly generated cartilage tissue in the low concentration cartilage cell group reached 30% of that in positive control group, the scaffold was obviously shrunken and deformed. Only regional and discontinuous cartilage tissues were formed, and the amount of newly formed cartilage was obviously less than that in the co-culture group and the positive control group.</p><p><b>CONCLUSIONS</b>Chondrocytes can provide a micro-environment for the formation of cartilage, and also effectively induce BMSC to differentiate into chondrocytes and form tissue-engineered cartilage in vitro.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate cyclooxygenase-2 (COX-2) expression and its relationship with mismatch repair (MMR) protein expression and microsatellite instability (MSI) in hereditary nonpolyposis colorectal cancer (HNPCC).</p><p><b>METHODS</b>A total of 28 cases of colorectal adenoma and 14 cases of colorectal carcinoma were collected between July 2003 and July 2007 from 33 HNPCC families. Sporadic colorectal adenoma (n=32) and carcinoma patients (n=24) served as controls. With samples of tumor tissues and normal colonic mucosa collected from the patients, the protein expressions of COX-2 and MMR (hMLH1, hMSH2, and hMSH6) were examined with immunohistochemical assay. Frequency of MSI in five standard MSI loci BAT25, BAT26, D2S123, D5S346, and D17S250 were analyzed by means of polymerase chain reaction.</p><p><b>RESULTS</b>The rate of COX-2 high-expression was 53.6% (15/28) and 42.9% (6/14) in HNPCC adenoma and carcinoma; 62.5% (20/32) and 91.7% (22/24) in sporadic adenoma and carcinoma, respectively. That rate was lower in HNPCC carcinoma than in sporadic carcinoma (Pü0.05). MMR-deletion rate and percentage of high-frequency MSI (MSI-H) in HNPCC carcinoma were higher than those in sporadic colorectal carcinoma [both 71.4% (10/14) vs. 12.5% (3/24), both Pü0.01]. Among the 10 MMR-deficient HNPCC carcinoma patients, COX-2 low-expression was observed in 8 cases (80.0%), while COX-2 high-expression was observed in all of the 4 MMR-positive HNPCC carcinoma cases (Pü0.05). In comparison to MMR positive HNPCC carcinoma, HNPCC adenoma, and sporadic carcinoma, COX-2 expression was significantly lower in corresponding MMR-deficient cases (all Pü0.05). The rates of COX-2 low-expression in HNPCC adenoma, HNPCC carcinoma, and sporadic carcinoma with MSI-H were significantly higher than those in the cases with microsatellite stability (all Pü0.05).</p><p><b>CONCLUSION</b>COX-2 is expressed at a low level in HNPCC carcinoma, different from the high COX-2 expression in sporadic carcinoma.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To explore the clinicopathological features of non-familial colorectal cancer with high-frequency microsatellite instability (MSI-H).</p><p><b>METHODS</b>One hundred and fifty patients with colorectal cancer who had no family history were enrolled in this study from June 2006 to June 2008. Five standard microsatellite loci including BAT25, BAT26, D2S123, D5S346, and D17S250 were amplified with immunofluorescent polymerase chain reaction. The patient information including age, sex, and tumor location was recorded. Pathological features including differentiation, mucinous differentiation, histological heterogeneity, and Crohn's-like reaction were observed under light microscope. The presence of tumor-infiltrating lymphocytes (TLs, CD4+ and CD8+) was detected by means of immunohistochemistry. A regression equation was obtained by stepwise logistic regression analysis to evaluate the relationship between MSI-H phenotype in colorectal cancer and pathological features.</p><p><b>RESULTS</b>MSI-H phenotype occurred in 13.33% of the 150 patients with non-familial colorectal cancer. Poor differentiation, histological heterogeneity, Crohn's-like reaction, and presence of TLs were found to be independent factors to identify MSI-H non-familial colorectal cancer. Logistic regression equation showed an overall sensitivity of 70.0%, specificity of 99.2%, and accuracy of 95.3% in identifying MSI-H non-familial colorectal cancer.</p><p><b>CONCLUSION</b>MSI-H non-familial colorectal cancer manifests specific pathological features, which may be relied upon for effective identification of that disease.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To study of the role of nuclear transcription factor-κB (NF-κB) in high glucose-induced apoptosis in INS-1 cells.</p><p><b>METHODS</b>Rat insulinoma (INS-1) cells cultured in RPMI 1640 medium were treated with 11.1 mmol/L glucose, 33.3 mmol/L glucose, or 33.3 mmol/L glucose plus 5 µmol/L NF-κB inhibitors for 48 h. The expression of NF-κB subunit P65 protein in the cell nuclei was detected by Western blotting, IKK belta mRNA level by quantitative RT-PCR, and cell apoptosis by Annexin V-PI double staining.</p><p><b>RESULTS</b>Compared with the control levels, IKK belta mRNA levels of the cells significantly increased in response to 33.3 mmol/L glucose exposure (P<0.01), which also resulted in significantly increased P65 protein expression in the cell nuclei (P<0.01) and cell apoptosis rate (P<0.05). Compared with those in the high glucose group, the expression of IKK belta mRNA and P65 protein and cell apoptosis rate decreased significantly after treatment with 33.3 mmol/L glucose plus 5 µmol/L NF-κB inhibitors (P<0.05).</p><p><b>CONCLUSION</b>High glucose induces NF-κB activation in INS-1 cells, and inhibition of NF-κB activation may protect INS-1 cells from high glucose-induced cell apoptosis.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To observe the effect of glucagon-like peptide-1 (GLP-1) on interleukin-1β (IL-1β)-induced damage in INS-1 cells and explore its possible mechanisms.</p><p><b>METHODS</b>INS-1 cells were divided into normal control group, IL-1β group, and GLP-1+IL-1β group with corresponding treatments. The cell viability was determined by MTT assay, the expression of IKKβ mRNA was detected by real-time PCR, and that of the protein p65 was detected by Western blotting.</p><p><b>RESULTS</b>In comparison with the normal control group, the cells in the IL-1β group showed a significantly decreased viability by 29% (P < 0.01); compared with those in IL-1β group, the cells in GLP-1+IL-1β group exhibited an significant increase in the cell viability by 30% (P < 0.01). In comparison with the normal control group, the cells in IL-1β group showed an significantly increased expression of IKKβ mRNA (1.967 ± 0.091 vs 1 ± 0, P < 0.05); GLP-1 significantly reduced IL-1β-induced increment of IKKβ mRNA expression to 1.287 ± 0.084 (P < 0.05). IL-1β treatment significantly increased NF-κB protein expression as compared to the control level (0.814 ± 0.111 vs 0.396 ± 0.026, P < 0.01), and GLP-1 significantly inhibited such effect (0.622 ± 0.059, P < 0.05).</p><p><b>CONCLUSIONS</b>GLP-1 inhibits IL-1β-induced β-cell damage probably by inhibiting the NF-κB pathway.</p>

ABSTRACT

Objective To evaluate the effects of socioeconomic status on the distribution of cardiovascular risk factors and clinicaltreatments of patients with acute myocardial infarction in Beijing.Methods In Beijing, a prospective, muhi-center, registration study was carried out which including 800 patients who were consecutively hospitalized for ST-segment elevation acute myocardial infarction within 24 hours after event attack in 19 different hospitals in Beijing between November, 2005 and December, 2006.Indicators of socioeconomic status included self-reported personal income (<500, 500-2000,>2000 RMB/month), educational attainment (≤ 12 and > 12 years) and status of medical insurance (yes/no).According to categories of education, patients were categorized into two groups of lower socioeconomic status and higher socioeconomic status. Differences of cardiovascular risk factors and clinical treatments were compared across the two groups respectively. Results Proportion of diabetes and hyperlipidemia in patients with higher socioeconomic status was much higher than that of patients with lower socioeconomic status (P<0.05, P<0.01 respectively). Patients with lower socioeconomic status were more likely to be smokers (P <0.05). The rates of receiving coronary angiography and PTCA were much lower in patients with lower socioeconomic status. Medical insurance and income were the most important two socioeconomic factors determining the use of PTCA. Conclusion Compared to patients with lowersocioeconomic status,patients with higher socioeconomic status had higher rates of hyperlipidemia and diabetes but lower smoking rate among cardiovascular risk factors. The rates of receiving interventional therapies were much lower in patients with lower socioeconomic status.
