Objective:To detect the pain status and the pain management of home-based advanced cancer patients, and to investigate the key factors impacting the satisfaction on pain management.Methods:Totally the data of 138 cases from the hospice department in the duration from Jan. 2019 to Jun. 2019 were collected and analyzed by χ2 test with SPSS 23.0. Results:109 cases in 138 cases received analgesics treatment before, 54.13% of these participants expressed satisfaction with the effect of their pain management, and 45.87% showed unsatisfied on their pain management. Cancer clinical stage and PMI (pain management index) were both detected to be the significant factors for satisfaction of pain management ( P<0.05, P=0.029; P<0.01, P=0.001) . Conclusions:Cancer clinical stage and PMI are found to be related to the satisfaction for pain management. The percentage of patients who use opioids increased. while there was still a part of patients suffering from inadequacy of pain management. The pain management for home-based advanced patients needs to be paid more attention by medical staff.

The effect and mechanism of mulberry leaves extracts (MLE) on glucose uptake of insulin-resistant HepG2 cells in vitro was explored. The insulin resistant models of HepG2 were induced by high concentration of insulin for 24 h. The models were incubated in a buffer containing mulberry leaves extracts. The glucose consumption was detected by glucose assay kits and the AMP-activated protein kinase (AMPK), Akt activation was examined by Western blotting. Mulberry leaves polysaccharides, mulberry leaves flavonoids and mulberry leaves extracts advanced glucose uptake of insulin-resistant HepG2 cells; Mulberry leaves extracts enhance phosphorylation of AMPK. Mulberry leaves extracts do not change the phosphorylation status of Akt. The glucose consumptions of insulin resistant model of HepG2 were promoted by mulberry leaves extracts. MLE stimulates HepG2 cell AMPK activity acutely without changing the Akt activity.

AIM: To explore a simple, reliable method for tissue processing and section staining by extracting DNA from the manually microdissectioned specimen, and to identify whether the extracted DNA is useful in the following study at molecule level. METHODS: The experiment was performed at the pathological laboratory of Guangdong Medical College from July 2004 to July 2007. The paraffin imbedding tissue sections of cervical cancer were thoroughly deparaffinized after mounted on slides for a long period of time. The nucleus was slightly stained with hematoxylin and microdissectioned under inverted microscope. The microdissectioned samples were put into EP tubes filled with digestion buffer to split the cells and then the DNA was extracted. During the whole course, PE tubes did not change, and the complicated phenol/chloroform extraction did not perform. The DNA extraction was rapid and simple. RESULTS: The DNA was measured by the spectrophotometer with concentrations from 0.14 to 5.25 g/L and absorbance values of A260/A280 were 1.6-1.8. All samples were amplified with PCR to produce expected length specific target fragment (231 bp). CONCLUSION: Rapid DNA extraction after manual tissue microdissection can produce adequate amount of DNA and maintain good quality of DNA template for PCR. The DNA meets the need of the following molecular experiments.

Objective:
To evaluate the clinical feasibility and advantages of ultrasound guided mammotome biopsy for micro-calcifications visible in mammography.
Methods:
A total of 12 patients with mammography-revealed micro-calcifications examined by ultrasound guided vacuum-assisted biopsy in our hospital from Jun. 2017 to Dec. 2018 were enrolled in this study and their medical records data were analyzed.
Results:
All 12 patients had accepted pre-biopsy ultrasound localization and all micro-calcifications were successfully excised. Among 12 cases, 4 were revealed as benign breast diseases and 8 were diagnosed as breast cancer.
Conclusions
Ultrasound guided mammotome biopsy is found to be an alternative method to stereotactic biopsy in patients with US-detectable micro-calcifications, and re-scan ultrasonography focusing on the specific microcalcification area may be helpful for improving the ultrasound detection rate of micro-calcifications.

Objective To predict the core targets and action pathways of Hedysari Radix based on UPLC-MS/MS and network pharmacology methods,and to verify the results of network pharmacology by molecular docking and molecular dynamics techniques.This article aims to investigate immune regulation mechanism of effective components absorbed into blood from Hedysari Radix.Methods Qualitative quantification of effective components absorbed into blood from Hedysari Radix were operated by using UPLC-MS/MS technique.The corresponding targets of effective components absorbed into blood from Hedysari Radix were screened by TCMSP and HERB databases.Targets of immune-related disease were obtained through DisGeNET,OMIM,TTD,and MalaCards databases.The network of"components absorbed into blood from Hedysari Radix-immune-related diseases"was then constructed.GO and KEGG enrichment analysis and mapped the PPI network were performed.Molecular docking and molecular dynamics techniques were applied for validation.Results A total of 8 prototype components absorbed into blood,synergistically acting on 101 targets,were identified by UPLC-MS/MS.They mediated 538 biological processes including immune response,positive regulation of gene expression,receptor binding,and cytokine activity.Meanuhile,116 signaling pathways,such as HIF-1,Toll-like receptor,JAK-STAT,T cell receptor,PI3K-Akt,and FoxO etc.were involved.The core targets were MAPK14,PTGS2,MMP9,PPARG,CCND1,etc..The results of molecular docking showed that formononetin and calycosin had strong docking binding activity with MAPK14.And molecular dynamics simulations further demonstrated that the binding between MAPK14 and formononetin or calycosin had good structural stability and binding affinity.Conclusion The results of serum pharmacochemistry,network pharmacology and molecular dynamics were verified to reveal the material basis and mechanism of Hedysari Radix in regulating immunity.The aim of this study is to provide scientific basis for its immunomodulatory mechanism.
