Objective To compare and analyze the surgical and non-surgical treatment results of hypertensive cerebrat hemorrhage.Methods 29 vases of hypertensive cerebral hemorrhage patients are randomly divided into two groups:13 cases were treated by surgical treatment,and 16 cases were treated by medicine treatment.Results In surgical group,dead 3 cases,plant survival 5 eases,death disablity rate is 62%;and in non-surgical group:dead 1 case,plant survival 5 eases,death disablity rate is 44%.Conclusion There is no significant difierence between surgical and non-surgical treatment of hypertensive cerebral hemorrhage.It should be thought more to use surgical treatment on hypertensive cerebral hemorrhage.

Ventilator aid respiration is important for patients with respiratory failure.But the negative emotional reaction of patient during connection and disconnection to ventilator will seriously influence the therapeutic effect,so a comprehensive underatanding about the emotional characteristic and dynamic emotion change of patient is of primary importance,because it will improve the diagnostic and therapeutic level,give patient personalized take care and make effective therapeutic plan,which will help keep a good emotion state for patient and accelerate recovery.This article will discuss how to use ventilator more effectively and economically.

Background:
Peste des petits ruminants (PPR), caused by the PPR virus (PPRV), is an acute and fatal contagious disease that mainly infects goats, sheep, and other artiodactyls.Peripheral blood mononuclear cells (PBMCs) are considered the primary innate immune cells.
Objectives:
PBMCs derived from goats were infected with PPRV and analyzed to detect the relationship between PPRV replication and apoptosis or the inflammatory response.
Methods:
Quantitative real-time polymerase chain reaction was used to identify PPRV replication and cytokines expression. Flow cytometry was conducted to detect apoptosis and the differentiation of CD4+ and CD8+T cells after PPRV infection.
Results:
PPRV stimulated the differentiation of CD4+ and CD8+ T cells. In addition, PPRV induced apoptosis in goat PBMCs. Furthermore, apoptosis and the inflammatory response induced by PPRV could be suppressed by Z-VAD-FMK and Z-YVAD-FMK, respectively.Moreover, the virus titer of PPRV was attenuated by inhibiting caspase-1-dependent apoptosis and inflammation.
Conclusions
This study showed that apoptosis and the inflammatory response play an essential role in PPR viral replication in vitro, providing a new mechanism related to the cell host response.

BRAF is a serine/threonine kinase that harbors activating mutations in ∼7% of human malignancies and ∼60% of melanomas. Despite initial clinical responses to BRAF inhibitors, patients frequently develop drug resistance. To identify candidate therapeutic targets for BRAF inhibitor resistant melanoma, we conduct CRISPR screens in melanoma cells harboring an activating BRAF mutation that had also acquired resistance to BRAF inhibitors. To investigate the mechanisms and pathways enabling resistance to BRAF inhibitors in melanomas, we integrate expression, ATAC-seq, and CRISPR screen data. We identify the JUN family transcription factors and the ETS family transcription factor ETV5 as key regulators of CDK6, which together enable resistance to BRAF inhibitors in melanoma cells. Our findings reveal genes contributing to resistance to a selective BRAF inhibitor PLX4720, providing new insights into gene regulation in BRAF inhibitor resistant melanoma cells.
