Significances of Peripheral Inflammatory Cells and Neutrophil/Platelet-Lymphocyte Ratio in Breast Cancer after Resection

Introduction: Breast cancer had become top leading cause of death in Taiwan and endangered women’s health worldwide. Therefore, we try to invest the peripheral inflammatory cell counts and neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) from our routine practice for the predictor of prognosis of breast cancer after resection. Patients and Methods: There were 574 breast cancer patients accepted surgical resection and registered in Cancer Registry Center of our hospital. Patient’s basic profiles, peripheral neutophil, lymphocyte and platelet count were measured for study. The scales of NLR and PLR were derived from the lower and higher normal range in cell count from neutrophil, lymphocyte and platelet respectively. Therefore, the scales for NLR and PLR were ≤1.62, 1.63 - 2.57, ≥2.58 and ≤224, 225 - 253, ≥254 respectively for analysis. Results: Poor 5-yr survival rate was found if higher cell counts of neutrophil and platelet (p ≤ 0.05). Three scales of NLR were ≤1.62, 1.63 - 2.57, ≥2.58, and their 5-year survival rates were 94%, 91% and 84% respectively (p = 0.019). In the subgroup of HER-2 (negative), and 3-Negative breast patients had a higher NLR of poor prognosis. But higher PLR was found less in 3-Negative and non in 3-Positive patients (p = 0.039). The PLR was ≤224, 225 - 253, ≥254 and their 5-year survival rates were 92%, 87%, and 64% respectively (p = 0.001);Multivariate Cox regression model for predictor of breast cancer patients who have 3.39 (PLR ≥ 254) and 2.45 (NLR ≥ 2.58 ) times risk (p = 0.02 and p = 0.002) of poor prognosis respectively. Conclusion: Peripheral inflammatory cell counts are easily to take in our clinical practice and have a potential role as predictors of prognosis. We have to pay attention to the trends of peripheral inflammatory cell count and their ratio in our clinical practice where possible.

Role of Pre-Operative of Neutrophil/Lymphocyte and Platelet/Lymphocyte Ratio in Prognosis of Hepatocellular Carcinoma

Introduction: Hepatocellular carcinoma (HCC) has a poor prognosis and is ranked in the top 2 leading causes of death in Taiwan. The clinical features which affect survival rate should be noticed for alarming. We tried to study the neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) for the predictor of prognosis of HCC. Patients and Methods: A total of 525 patients with HCC were undergone surgical or non-surgical treatment registered in Cancer Registry Center of our hospital. The clinical features included patient’s basic profiles, and neutrophil, lymphocyte and platelet count in the peripheral blood at the time of diagnosis. The ratio of neutrophil/lymphocyte and platelate/lymphocyte was measured and their survival rates were analyzed based on their ratio scales. Results: Three scales of NLR and PLR were ≤1.62, 1.63 - 2.57, ≥2.58 and ≤224, 225 - 253, ≥254 respectively. Either higher NLR ≥ 2.58 or higher PLR ≥ 254 was found mostly in the male and TMN stage III and IV with a significant difference (P < 0.01). The 5-year survival rates of NLR ≤ 1.62, 1.63 - 2.57, ≥2.58 were 33.9%, 33.7%, and 16.7% respectively (P < 0.001). The mean survival times were 34.1 ± 1.4, 29.3 ± 8.1, and 14.2 ± 2.1 months for the scales of PLR ≤ 224, 225 - 253, and ≥ 254 respectively. The 5-year survival rates were 25.5%, 36.4%, and 7.7% for the groups of the PLR ≤ 224, 225 - 253, and ≥254 respectively (p < 0.001). Conclusion: Neutrophil, lymphocyte and platelet are players in cancer growth and have a potential role as predictors of survival in our HCC patients. Therefore, we should pay more attention to the higher NLR or PLR which will result in a poorer prognosis in our patients.

Two near-infrared highly sensitive cyanine fluorescent probes for pH monitoring

Two near-infrared（NIR） p H-activated heptamethine indocyanine probes with quaternary ammonium unit were designed and synthesized. The absorption and emission titrations indicate that cationic structure improves the cyanine dye＇s aqueous solubility and these two probes exhibit highly sensitive response to p H in acid condition. Their fluorescence intensities both gradually increase about 25-fold from p H 7.60 to 3.00 with p Ka values of 4.72 and 4.45 respectively, which are suitable for studying acidic organelles in living cells. Moreover, their fluorescence intensities are linearly proportional to p H values in the range of 5.50–4.00. These results are probably attributed to the protonation of the indole nitrogen atoms, which are verified by 1H NMR spectra. Furthermore, these two probes can achieve real-time imaging of cellular p H and detection of p H in situ in living He La cells due to their excellent properties,including good reversibility, desirable photostability, high selectivity, low cytotoxicity and remarkable membrane permeability.

Expert consensus on management principles of orthopedic emergency in the epidemic of coronavirus disease 2019

Since December 2019,many patients in Wuhan sustained pneumonia with unknown causes.[1,2]A part of severe patients developed acute respiratory distress syndrome or septic shock,and even death.On January 7,2020,Chinese researchers have for the first time detected a new coronavirus.On January 20,2020,the National Health Commission issued Announcement No.1 of 2020,which included the new coronavirus pneumonia as a Class B infectious disease,and conducted epidemic prevention and control according to the Class A infectious disease.This new kind of pneumonia has been named coronavirus disease 2019(COVID-19).The sixth edition of"Diagnosis and Treatment Scheme for New Coronavirus Infected Pneumonia"points out that the main transmission routes include respiratory droplets and close contact transmission.There is a possibility of aerosol transmission in a relatively closed environment with prolonged exposure to high concentrations of aerosol.New coronavirus pneumonia has a certain incubation period.

Piezochromic luminescence and aggregation induced emission of 9,10-bis[2-(2-alkoxynaphthalen-1-yl)vinyl]anthracene derivatives

Four derivatives of 9,10-bis[2-（2-alkoxynaphthalen-1-yl）vinyl]anthracene（BNAs） were designed,successfully synthesized and characterized by spectrofluorometer, powder wide-angle X-ray diffraction（PXRD） and differential scanning calorimetry experiments（DSC）, etc. It was found that these compounds exhibited aggregation-induced emission phenomenon. Moreover, these target compounds displayed reversible color change from yellow to orange upon pressing and annealing process. Interestingly, all of BNAs obviously presented red-shifted piezofluorochromic（PFC） properties and behaved mainly length dependence of alkoxy group, in which, BNA displayed the largest PFC spectral shift（DlPFC= 26 nm）. The PXRD profiles demonstrated the transformation from crystalline to amorphous state upon grinding, and the mechanism of PFC behaviors was proposed. Thus, changing the length of alkoxyl chain could be an alternative way to tune their PFC behaviors.
