ABSTRACT

Currently, the epidemic of 2019 coronavirus disease (COVID-19) is still ongoing. The characteristics including high contagiousness, herd susceptibility and clinical phenotype diversity, made a serious influence on people’s daily life and rountine therapy for other diseases. Breast dieases are clinical common diseases. In the central epidemic area of COVID-19, Hubei province, especially Wuhan, the clinical specialists of breast diseases should consider all of the following factors comprehensively: the prevention of COVID-19, the diagnosis and treatment of breast diseases and the accessibility of medical resources. Besides, we should select the appropriate therapy and optimize treatment process so as to prevent the propagation and cross infection of COVID-19 as well as manage the breast diseases without delay. Therefore, we carried out some management proposals of the patients with breast diseases in the central epidemic area during the epidemic of COVID-19 on the basis of conventional treatment guidelines and clinical experiences. The suggestions and corrections from colleagues will be welcomed.

ABSTRACT

Objective To study the immunoregulatory effects of emodin on macrophages during Brucella infection and to provide theoretical and experimental basis for developing new drugs to treat brucello-sis. Methods Bone marrow cells were isolated from BALB/c mice and cultured with MG-CSF to induce differentiation. Flow cytometry was used to detect the differentiation of bone marrow cells into macrophages (MΦ) by using FITC-labeled mouse anti-F4/80 antibody and PE-labeled anti-CD11b antibody. MTT meth-od was used to detect the influences of various concentrations of emodin on the survival rate of MΦ. Doxy-cycline was used as the control to compare half maximal inhibitory concentrations (IC50) of the two drugs. MΦ were cultured with Brucella at a ratio of 100 : 1 for 4 h. MΦ and Brucella were further cultured for 1, 6,12,24 and 48 h after adding emodin. Effects of emodin on the survival of MΦ were analyzed by colony counting method. ELISA was performed to detect the levels of TNF-α, IL-6 and IFN-γ in culture superna-tants. Results On day 8 of culturing,91.28% of bone marrow cells differentiated into macrophages. The IC50of emodin(608.4 μg/ml) was significantly higher than that of doxycycline(225.5 μg/ml). The logC-FU values of emodin stimulation groups (6,12,24 and 48 h) were significantly lower than those of blank control groups. Among all emodin stimulation groups, the 24 h group had the lowest logCFU value, which was also lower than that of the doxycycline treatment group. The levels of TNF-α,IL-6 and IFN-γ in 6,12 and 24 h emodin stimulations group increased significantly as compared with those of the corresponding con-trol groups. The levels of TNF-α, IL-6 and IFN-γ peaked at 24 h of culturing Brucella-infected MΦ with emodin. No significant difference in IFN-γ level was found between the 12 and 24 h emodin stimulation groups [(74.233 ±4.416) pg/ml vs (78.328 ±8.932) pg/ml]. Conclusion Emodin may enhance the ability of macrophages to kill Brucella through promoting the expression of TNF-α,IL-6 and IFN-γ.

ABSTRACT

Objective · To study the electrophysiological effect of (S)-OTS·HCl on the heart. Methods · The conventional intracellular recording, electrocardiograph (ECG) and Langendorff cardiac perfusion technique were employed to investigate the effect of (S)-OTS·HCl on in-vivo and in-vitro hearts of guinea pigs and rabbits. Results · (S)-OTS·HCl could bind to M2 muscarinic receptors and dose-dependently prolong the RR intervals significantly in vivo. It had no effect on resting potential (RP), action potential amplitude (APA), and maximum upstroke velocity of phase 0 (Vmax) of ventricular myocytes. Instead, 1×10-5 mol/L (S)-OTS·HCl could shorten the action potential duration at 50 percent repolarization (APD50) and APD90 to 91.6% and 90.9%, respectively. And the spontaneous depolarization rate of phase 4 (SDR) of sinus nodes was reduced to its 13.7% when rabbit sinus nodes were exposed to 1×10-7 mol/L (S)-OTS·HCl. (S)-OTS·HCl could inhibit Ca2+channel effectively. It decreased APA and Vmax of sinus nodes and attenuated the cardiac contractility in vitro. Conclusion · (S)-OTS·HCl is a potent cholinergic agonist and has negative chronotropic, dromotropic, and inotropic effects on hearts via binding to M2 muscarinic receptors.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the effect of acute blood loss on postoperative cognitive function of aged spontaneously hypertensive rats (SHRs).</p><p><b>METHODS</b>Forty aged male SHRs were randomized into sham hemorrhage group (group A, n=13), 20% hemorrhage group (group B, n=13) and 40% hemorrhage group (group C, n=14). The rats were subjected to acute loss from the femoral artery and subsequent fluid replacement with lactated Ringer's Solution (3 folds of the blood loss volume). All the rats underwent Morris water maze test to assess the visuospatial memory and learning ability, and were then decapitated to observe the pathological changes of the hippocampus.</p><p><b>RESULTS</b>The latency of reference memory in group C was significantly prolonged after the operation (P=0.002), but the working memory and learning capacity showed no significant differences between the 3 groups. Immunochemistry did not reveal significant differences in p-CREB expressions in the hippocampal CA1 region among the groups, but volume reduction of some neurons was noted in the CA1 region in group C.</p><p><b>CONCLUSION</b>Varying degrees of acute hemorrhage can result in different effect on postoperative cognition in aged SHR. Acute hemodilutional anemia to 40% of baseline can cause reference memory impairment with cell volume reduction of the neurons in the hippocampal CA1 region but does not affect the working memory and learning capacity or p-CREB expression.</p>

ABSTRACT

ObjectiveTo investigate the value of ultrasonography in the diagnosis of the papillary thyroid microcarcinoma (PTMC) in patients with Hashimoto’s thyroiditis (HT).MethodsThis retrospective study used data from Ruijin Hospital of Shanghai Jiaotong University of Medicine during November 2012 to December 2013. A total of 111 small thyroid nodules (75 PTMC/36 benign nodules) with 107 HT cases which were pathologically conifrmed were included in this study. The sonographic characteristics of nodules were investigated, including nodule aspect ratio, shape, border, margin, acoustic halo, internal structure, echo level, microcalciifcations, rear acoustic attenuation, vascular pattern and extent of the blood supply and the types of thyroid tissue echogenicity. Chi-square test and Fisher′s exact probability method was used to compare the differences of the sonographic characteristics between the benign nodules and malignant nodules. With surgical pathology as the gold standard, computing the value of ultrasonography in the diagnosis of PTMC with HT, including the sensitivity, speciifcity, diagnostic accuracy, positive predictive value and negative predictive value.ResultsA total of 111 thyroid tiny nodules (75 PTMC/36 benign nodules) with 107 HT cases which were pathologically conifrmed were included in this study. The results showed 111 small thyroid nodules as solid hypoechoic. Four indexes between PTMC and benign nodules had statistical signiifcance, such as margin, microcalciifcations, vascular pattern and extent of the blood supply. The other six indexes between PTMC and benign nodules had no statistical significance, such as aspect ratio, shape, border, acoustic halo, rear acoustic attenuation and the types of thyroid tissue echogenicity. Ultrasound diagnostic accuracy of small tyroid nodules in patients with HT was 74.77% (83/111). The sensitivity, specificity, diagnostic accuracy, positive predictive value and negative predictive value of the ultrasound diagnosis of PTMC were 93.33% (70/75), 36.11% (13/36), 74.77% (83/111), 75.27% (70/93), and 72.22% (13/18), respectively.ConclusionsCompared with general population, some classic ultrasound features became less effective in patients with HT. However, ultrasonography has some differential diagnostic value in these cases.

ABSTRACT

This study investigated the "homing" phenomenon in hepatocellular carcinoma (HCC). The "homing" specificity of endothelial progenitor cells (EPC) by establishing an orthotopic implantation model in nude mice. EPCs harvested from the marrow cells were separated by density gradient centrifugation. Fluorescence microscope, flow cytometry (FCM) and double fluorescence staining with FITC-UEA-I and DiI-ac-LDL, were employed to identify the cells. 4',6-diamidino-2-phenylindole (DAPI) labelling and real-time PCR were used for detecting the expression of CD133 and chemokines to trace and observe the distribution of EPCs. Our results showed that the distribution rate of EPCs was obviously higher than that in other important organs and the negative control group. Detection of CD133 and chemokines yielded similar results in difference tissues. Our experiment confirmed that the chemotaxis of EPCs does exist in HCC. Moreover, HIF-1α, SDF-1 and VEGF might play important roles in the "homing" of EPCs in HCC. EPCs might be a potential candidate for targeting vector of HCC for gene therapy.

ABSTRACT

Two isolation methods for sorting of endothelial progenitor cells (EPCs): from peripheral blood mononuclear cells (PBMCs) and CD133(+) enriched cells were compared, by defining the cell morphology, phenotype, reproductive activities and function in vitro, to provide a reference for clinical application of EPCs. PBMCs from healthy subjects were used either directly for cell culture or for CD133(+) sorting. The two groups of cells were cultured in complete medium 199 (M199) for 7 to 14 days and the phenotypes of EPCs were analyzed by FACS. The proliferation of differentiated EPCs was studied by MTT assay, and the VEGF concentration was measured using an ELISA kit. ECM gel experiment and migration assay were performed in vivo. The results showed that PBMCs produced more colony-forming units (CFU) than CD133(+) enriched cells from the same volume of blood (P<0.01). From day 7 to 14, the two groups showed decreased expression of hematopoietic stem cell markers and increased level of endothelial markers, but CD144(+) cells in CD133(+) group were less than in PBMCs group (P<0.01). PBMCs group secreted more VEGF than CD133(+) group on the day 7 (P<0.01). As compared with CD133(+) group, PBMCs group had more potent potential of proliferation and vascularization in vitro. It was concluded that CD133(+) sorted cells showed a lower capacity of differentiation, secretion, proliferation and vascularization in vitro, suggesting that CD133-negative cells may be a preferential way to get EPCs for clinical therapy.

ABSTRACT

AIM: To compare the methods of two currently employed isolation methods for endothelial progenitor cells (EPCs): from total peripheral blood mononuclear cells (PBMCs) and from enriched CD133~+ cells, by defining the cell morphology, phenotype, reproductive activities and function in vitro, providing a reference for clinic application. METHODS: PBMCs from the healthy subjects were used for CD133~+ sorting or not. The two groups of isolated cells were suspended in complete medium M199 for 7 d to 14 d. EPCs phenotype were characterized by FACS. The proliferation of differentiated EPCs was studied by MTT assay, and VEGF concentration was measured using an ELISA kit. Matrigel experiment and migration assay were imitated vascularization in vivo. RESULTS: PBMCs produced more colony-forming units (CFU) than CD133~+ cells from the same volume of blood (P<0.01). From 7 d to 14 d, the two groups show decreased expression of hematopoietic stem cell markers and increased level of endothelial markers, but CD144~+ cells in CD133~+ group were lower than those in PBMCs groups (P<0.01). Cells in PBMCs group secreted more VEGF than that in CD133~+ group on 7 d (P<0.01). Compared to CD133~+ group, PBMCs group showed more potential of proliferation and vascularization in vitro. CONCLUSION: CD133~+ sorted cells show a lower capacity of differentiation, secretion, proliferation and vascularization in vitro, which is unable to differentiate to mature endothelial cells, indicating that it's not a preferential way to obtain EPCs for clinic therapy.

ABSTRACT

Summary: To investigate the difference in expression of hTERT gene between HbsAg-positive human hepatocellular carcinoma (HCC) and HbsAg-negative HCC and to explore the relationship between HBV infection and hTERT gene expression in HCC. The expression of hTERT protein in 30 cases of HbsAg positive HCC and 17 cases of HbsAg negative HCC was detected by immunohistochemistry (SP method), and the expression of hTERT mRNA was analyzed by reverse transcription polymerase chain reaction (RT-PCR). t-test, Chi-squared test and cochran- armitage trend test were used to see whether there was an interrelation between HBsAg and hTERT gene in HCC. The expression of hTERT protein was mostly located in plasm and occasionally in the nucleus of liver cancer cells. The positive rate of hTERT protein and hTERT mRNA in HbsAg positive HCC- 93.33 % (28/30) and 83.33 % (25/30) respectively which were much higher than those in HbsAg negative HCC- 52.94 % (9/17), 47.06 % (8/17) (P<0.01) respectively. HbsAg is related to hTERT gene expression in human hepatocellular carcinoma. The hTERT gene activated by the efficacious ingredient of HBV may play an important role in hepatocellular transformation and carcinogenesis.

ABSTRACT

The clinical significance of phosphatase and tensin homolog deleted on chromosome ten (PTEN) protein expression and the correlation between the expression of PTEN and phosphorylation of protein kinase B (PKB/AKT) in human hepatocellular carcinoma (HCC) were investigated.The expression of PTEN and phospho-AKT was detected by SP immunohistochemical technique and Western blotting in 35 cases of HCC, 15 cases of liver cirrhosis and 8 cases of normal tissues. The correlation between the expression of PTEN and PKB/AKT in HCC was analyzed. The results showed that the positive expression of PTEN in HCC (62.9 %, 0. 085±0. 021) was significantly lower than that in liver cirrhosis and normal tissues (P<0.01). The expression level of PTEN was related to the differentiation degree of HCC and the status of metastasis (P<0. 05). Western blotting revealed a significant inverse correlation between PTEN and phospho-AKT (r=-0. 818, P<0.01). These results demonstrated that down-regulation or loss of PTEN, which may not be able to effectively inhibit the hyper-phosphorylation of PKB/AKT, might play an important role in tumorigenesis and progression of HCC.

ABSTRACT

In order to investigate the changes of vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) expression in residual hepatocellular carcinoma (HCC) after transcatheter arterial chemoembolization (TACE), the expression levels of VEGF and bFGF expression in specimens surgically removed from 48 HCC patients were detected by immunohistochemical methods, and staining intensity of VEGF and bFGF was assessed by a computer-assisted image-analyzer. Among the 48 patients, 25 underwent partial hepatectomy alone (single operating group), and 23 were subjected to second stage surgical resection after TACE (TACE group). The results showed that the average absorbance value (A) of VEGF was higher in TACE group than that in single operating group (0.152 +/- 0.021 vs 0.131 +/- 0.012, P < 0.01). The Average A of bF-GF in TACE group was 0.127 +/- 0.023, higher than in single operating group (0.111 +/- 0.016, P < 0.05). These results suggested that TACE of HCC can up-regulate the expression of VEGF and bFGF in HCC tissues possibly due to anoxia and ischemia.
