Background Formaldehyde is a toxic gas. Automatic iodine analyzer is a high-throughput automatic instrument for measuring water and urine iodine, but at present, there is a lack of its application in the determination for air formaldehyde. Objective To develop a high-throughput method for air formaldehyde determination with an automated iodine analyzer. Methods The formaldehyde in the air was collected with an atmospheric sampler, and 1.0 mL of working curve solution, standard solution, and sample solution were loaded to an automated iodine analyzer. Solution resting time and instrumental parameters, including detection wavelength, sample needle depth, and regent₂ (R₂) reaction time were optimized. Finally, the method was validated by precision, detection and quantification limits, and spiked recovery. Four different concentrations of standard substance solutions and 10 air samples were collected for comparison between manual measurement method and high-throughput fully automated detection method. Results The final optimized conditions in this study were: 2 h and above resting time for prepared solution, and the optimal parameters of the instrument work were: detection wavelength at 660 nm, sample needle depth at 2800, and R₂ reaction time at 900 s. Under the optimized conditions the linear equation of the method was optical density(D) =0.9787 × formaldehyde concentration (C) − 0.0364 and the correlation coefficient was 1.0000. The limits of detection (LOD) and quantification (LOQ) were 0.015 μg·mL⁻¹ and 0.052 μg·mL⁻¹ , respectively. The relative standard deviations (RSDs) of the intra-day precision experiments were 1.35% and 1.18% for the two different concentrations of standard sample solutions. The RSDs of the inter-day precision experiments were 1.82% and 1.50%, respectively. The recoveries ranged from 96.8% to 107.4%. The results produced by spectrophotometry and automated detection method in the comparison study were identical, and the measurements of selected four concentrations of standard solutions were within the uncertainty range. Conclusion The method established in this study features small solvent dosage, fully automated high throughput, comparable sensitivity to the national standard method, high accuracy, and inter-day and intra-day precision with a recovery rate above 96%. It can provide strong technical support for the determination of air formaldehyde.

Despite seminal studies in the 1920s by Warburg showing a characteristic metabolic pattern for tumors, cancer bioenergetics has otfen been relegated to the backwaters of cancer biology. Recent studies have shown that metabolism in the tumor tissue is far more complicated than we previously knew. Despite vigorous glycolysis, in fact, the tumor tissue still retains mitochondrial aerobic metabolism. Mitochondria is one of the main sites of the biosynthesis process of tumor cells. Recent studies revealed that abnormal fatty acid metabolism. Amino acid metabolism plays a key role in the tumorigenesis. The metabolic network in tumor cells was reprogrammed, leading to nutrition lfux reorganization and re-direction. Metabolism reprogramming in tumor cells facilitates the balance between the needs of energy supply and the synthesis of biological macromolecules. Targeting cell metabolism is not intended to interfere the energy supply of tumor cells but to affect the synthesis of metabolic rate, thereby inhibiting the proliferation of the tumor. hTe review focuses on the importance of metabolic reprogramming in tumor development and cancer therapy. We summarize what is currently known about metabolic reprogramming and establish a framework to understanding its contribution to the altered metabolism of cancer cells.

This study was aimed to summarize main-bone structure of cantharidin-based small molecules and facts about three typical candidates including its origin, physical-chemical properties and general synthetic approaches. Basic chemical and pharmacological information as well as development of anti-cancer activities, which were related to cantharidin, norcantharidin and their analogues were reviewed, especially the relationship between the structures and their inhibitory activity and selectivity of serine-threonine protein phosphatases PP1, PP2A and PP2B in cancer treatment. The designs and developments of new biological cantharidin-based small molecules were also reviewed.

Objective: To investigate the relationship of nm23 and VEGF expression with hilar lymph node micrometastasis and the prognosis of stage Ⅰ non-small cell lung cancer (NSCLC). Methods: Immunohisto-chemistry was used to detect nm23 and VEGF protein expression in primary cancer tissue and cytokeratins in 86 hilar lymph nodes from 40 patients with stage Ⅰ NSCLC. Kaplan-meier method and Log rank test were used to analyze the 5-year survival. Results: The rate of positive hilar lymph node micrometastasis was 12.5% for stage Ⅰ NSCLC. Lymph node micrometastasis was not statistically correlated with gender, age, histologic type, differentiation, primary tumor size or VEGF protein expression (P>0.05). But it was reversely associated with nm23 protein expression in primary cancer tissue of NSCLC (P<0.05). The 5-year overall survival of pa-tients with well-differentiated NSCLC, positive nm23 expression and negative lymph node micrometastasis was better than those with moderately and poorly differentiated NSCLC, negative nm23 expression and posi-tive lymph node micrometastasis (P<0.05). Lymph node micrometastasis and nm23 protein expression were identified as two independent prognostic factors for stage Ⅰ NSCLC by univariate Cox regression analysis.Conclusion: nm23 protein expression in pdmary cancer tissue of stage Ⅰ NSCLC is closely associated with hi-lar lymph node micrometastasis, nm23 protein and hilar lymph node micrometastasis are two independent prognostic factors for stage Ⅰ NSCLC. Patients with nm23 protein deletion and positive lymph node microme-tastasis have a poor prognosis.

Objective To study the effects of low dose sodium arsenite to human bone marrow mesenchymal stem cells(hBMSCs) differentiation during establishing of arsenic-resistant cell model. Methods hBMSCs were prepared in conventional method and continuously exposed to 1μmol/L sodium arsenite for ≥12weeks inv vitro. Forty-eight hours acute arsenite toxicity test was drived to assay if the cells acquired arsenic-resistance. The proliferation capacity of CAsE-hBMSCs was observed by the rate of colony formation.The expression of Oct-4 in CAsE-hBMSCs was assayed by RT-PCR and immunocytochemistry. The expression of ABCG2 in CAsE-hBMSCs was analyzed by RT-PCR. Results hBMSCs continuously exposed to 1μmol/L sodium asenite for ≥12 weeks exhibited dramatic resistance to acute arsenite toxicity. The LC 50 for acute arsenite exposure in CAsE-hBMSCs was 35.59μmol/L versus 18.04μmol/L in control cells. Compared to control cells, the CAsE-hBMSCs didn't show malignant proliferation ability. Expression of Oct-4 gene was positive in 4th, 18th passage hBMSCs and the hBMSCs induced by arsenite for 4 weeks but negative in CAsE-hBMSCs. The expression of Oct-4 protein was positive and weakly positive in 4th passage hBMSCs and CAsE-hBMSCs respectively, and the positive granules of Oct-4 distributed in cytoplasm. The expression of ABCG2 gene in CAsE-hBMSCs was obviously lower than that in control cells ( P <0.001). Conclusion Human bone marrow mesenchymal stem cells could be induced to differentiation by low dose sodium arsenite.

OBJECTIVE:To provide a reference for reducing adverse events due to off-label use of drugs and promoting ratio-nal use of intravenous drugs in Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine. METHODS:The pre-scriptions of intravenous drugs in 42 wards of our hospital from Jul. 2013 to Jun. 2014 were reviewed,and then off-label use of drugs were analyzed,where statistics was made mainly to drug overdose,the use of drugs at the concentration beyond the standards (including concentrations too high and too low) and associated conditions. RESULTS:There were 622 irrational prescriptions,in-cluding 60 concerning off-label use of drugs,accounting for 9.6% of irrational prescriptions,in which 40 were involved with the concentration which was too high,accounting for the highest percentage(66.7% of prescriptions related to off-label use of drugs), 17 were related to drug overdose(28.3% thereof),and 3 were in relation to the concentration which was too low(5.0% thereof). CONCLUSIONS:Pharmacy intravenous admixture service may,through the communication between the pharmacist and the doc-tor,refuse to make up the above-mentioned prescription which was found to be irrational(including that involving in off-label use of drugs)or make up such prescription after it is modified according to the requirements as specified in the label to reduce the occur-rence of off-label use of drugs so as to promote rational drug use.

Objective:To evaluate the antimicrobial effectiveness of Zhenzhu Mingmu eye drops according to the requirements de-scribed in Chinese pharmacopoeia (2010 edition). Methods:Totally 7 batches of Zhenzhu Mingmu eye drops from 7 enterprises were evaluated. All the samples were tested according to the requirements described in Chinese pharmacopoeia, and the testing points of 6h and 24h were added. Results:As for bacteria, the reduction value of staphylococcus aureus in 7 days treated with Zhenzhu Mingmu eye drops from enterprise e was 0. 61g, and that in 14 days was 1. 01g. That in 7 days treated with the eye drops from the other enter-prises was all above 1. 01g, that in 14 days was above 3. 01g, and that in 14-28 days kept stable. As for fungi, the number was stable from the beginning with the treatment of the eye drops from the seven enterprises. Conclusion:Although the type and content of bacte-riostatic agent in domastic Zhenzhu Mingmu eye drops are the same, there is difference in the antimicrobial effectiveness of the product from different enterprise.
