Abstract
Objective: To explore the correlation between electrical impedance indicators and commonly used nutritional indicators in neurocritical care patients. Methods: A cross-sectional study was conducted to collect 58 neurocritical care patients in neurosurgery Department of Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine from June to September 2022. Bioelectrical impedance tests were performed after surgery or one week after injury, and nutrition-related biochemical indicators of the patients were collected on the same day, including nutritional status related indicators, inflammation related indicators, anemia related indicators and blood lipid related indicators. The patients were assessed with acute physiology and chronic health evaluation (APACHE) Ⅱ score and sequential organ failure assessment (SOFA) score. Based on the results obtained, the patients were assessed with nutritional score and spearman correlation analysis. The correlations of electrical impedance with nutrition related indicators and nutrition risk related indicators were analyzed. The prediction model of nutritional status was constructed by multi-factor binary logistic regression. Stepwise regression was used to screen electrical impedance indicators related to nutritional status. The receiver operating characteristic (ROC) curve was plotted and the area under the curve (AUC) was calculated to evaluate the predictive ability of the nutritional status prediction model. Results: A total of 58 patients were collected, including 33 males and 25 females, and aged 72.0 (59.0, 81.8) years. Extracellular water (ECW) was positively correlated with interleukin 6 (r=0.529, P<0.001). The edema index [ECW/total body water (TBW)] was negatively correlated with albumin (r=-0.700, P<0.001), hematocrit (r=-0.641, P<0.001) and hemoglobin (r=-0.667, P<0.001). The phase angle was positively correlated with albumin (rRA=0.667, rLA=0.649, rRL=0.669, rLL=0.685, all P<0.001), hematocrit (rRA=0.600, rLA=0.604, rTR=0.565, rRL=0.529, rLL=0.602, all P<0.001) and hemoglobin (rRA=0.626, rLA=0.635, rTR=0.594, rRL=0.624, rLL=0.631, all P<0.001). By stepwise regression screening of predictive factors for nutritional status and incorporating age, gender and white blood cells as confounding factors into the model, the final model was obtained as follows: nutritional status=-0.01×age+1.22×gender-0.12×white blood cells+202.20×ECW/TBW+0.5 torso phase angle -82.16 [The OR value of ECW/TBW: 20.8 (95%CI: 3.7-117.1), P<0.001], with the AUC of 0.921. Conclusion: Bioelectrical impedance indicators have good correlations with commonly used clinical nutritional indicators, and can provide a new method for nutritional evaluation of neurocritical care patients.

Abstract
Objective: To analyze the clinical manifestations and laboratory features in patients with myeloid neoplasms complicated with clonal T large granular lymphocyte (T-LGL) proliferation. Methods: The clinical data of 5 patients with myeloid neoplasms complicated with clonal T-LGL proliferation from November 2017 to November 2018 in Institute of Hematology & Blood Diseases Hospital, Chinese Academy of Medical Sciences & Peking Union Medical College were analyzed retrospectively. Results: The median age was 60 years old. All patients had a history of abnormal peripheral blood cell counts for over 6 months. The absolute lymphocyte count in peripheral blood was less than 1.0×10(9)/L. In addition to the typical T-LGL phenotype, the immunophenotype was heterogenous including CD4(+)CD8(-) in 2 patients, the other 3 CD4(-)CD8(+). Four patients were αβ type T cells, the other one was γδ type. STAT3 mutation was detected in 1 patient by next-generation sequencing, the other 4 cases were negative. Conclusions: Clonal T-LGL proliferation with myeloid neoplasm develops in an indolent manner, mainly in elderly patients. Hemocytopenia is the most common manifestation. The diagnosis of T-LGL proliferation does not have specific criteria, that it should be differentiated from other T cell proliferative disorders, such as T-cell clones of undetermined significance. STAT3 or STAT5b mutation may help distinguish.

Abstract
Competitive field tests with α-fluorinated analogs of compounds III and IV (III-α-F and IV-α-F, respectively) of the boll weevil,Anthonomus grandis Boh., aggregation pheromone showed these compounds, when combined with the other pheromone components [(±)-I and II], to be as attractive as grandlure [(+)-I, II, and III+IV]. Dose-response curves constructed from electroantennograms of male boll weevils to serial stimulus loads of III, IV, III-α-F, IV-α-F, and the corresponding acyl fluorinated analogs (III-acyl-F and IV-acyl-F) showed the α-fiuorinated analogs to be as active as the pheromone components (threshold=0.1 μg), while the acyl fluorinated analogs had a 10-100 x higher threshold (=1-10 μg). Single-neuron recordings showed that IV neurons and II neurons (Dickens, 1990) responded to IV-α-F and III-α-F, respectively, while IV-acyl-F and III-acyl-F were inactive. Since a previous study showed compounds I, II, and IV to be essential for behavioral responses in the field, it seems likely that the activity of the α-fluorinated analogs observed here is due to the stimulation of IV neurons by IV-α-F as indicated in single neuron recordings.

Abstract
Fluorogenic substrates based on 4-methylumbelliferone (4-MU) have been widely used for the detection of phosphatase and glycosidase activities. One disadvantage of these substrates, however, is that maximum fluorescence of the reaction product requires an alkaline pH, since 4-MU has a pK(a) approximately 8. In an initial screening of five phosphatase substrates based on fluorinated derivatives of 4-MU, all with pK(a) values lower than that of 4-MU, we found that one substrate, 6,8-difluoro-4-methylumbelliferyl phosphate (DiFMUP), was much improved for the detection of acid phosphatase activity. When measured at the preferred acid phosphatase reaction pH (5.0), DiFMUP yielded fluorescence signals that were more than 10-fold higher than those of 4-methylumbelliferyl phosphate (MUP). DiFMUP was also superior to MUP for the detection of protein phosphatase 1 activity at pH 7 and was just as sensitive as MUP for the detection of alkaline phosphatase activity at pH 10. A beta-galactosidase substrate was also prepared based on 6, 8-difluoro-4-methylumbelliferone. This substrate, 6, 8-difluoro-4-methylumbelliferyl beta-d-galactopyranoside (DiFMUG), was found to be considerably more sensitive than the commonly used substrate 4-methylumbelliferyl beta-d-galactopyranoside (MUG), for the detection of beta-galactosidase activity at pH 7. DiFMUP and DiFMUG should have great utility for the continuous assay of phosphatase and beta-galactosidase activity, respectively, at neutral and acid pH.

Abstract
Two new fluorinated fluorescent dyes, 6,8-difluoro-7-hydroxy-4-methylcoumarin (Marina Blue) and 3-carboxy-6,8-difluoro-7-hydroxycoumarin (Pacific Blue), exhibit excellent photophysical properties among a series of novel fluorinated 7-hydroxycoumarins. Most of these fluorinated coumarins have quantum yields (0.63 to 0.89) equal to or higher than that of the parent compound (0.63), which, in combination with their lower pKaS and higher photostability, make them superior fluorescent dyes for use as reporter molecules in biological systems.

Abstract
The cytotoxicities of 2 derivatives of artemisinin B and 2 derivatives of artemisic acid (designated as Compound A, B, C, and D) were investigated, using trypan blue dye exclusion test and colony-forming units assay. At the concentration of 5 micrograms.ml-1, the inhibition rates of these 4 compounds against murine leukemia cell line P388 were > 85%. When tested against human hepatoma cell line SMMC-7721 at 25 micrograms.ml-1, the inhibition rates of Compound A, B, C, and D were found to be 92.3%, 96.9%, 84%, and 82.1%, respectively, and 27%, 8%, 37.8%, 1.7% against normal human embryonic lung cell line WI-38, respectively. These 4 compounds all showed an inhibition rate of 100% against human gastric cancer cell line SGC-7901 at 50 micrograms.ml-1.
