Pyroptosis is a newly discovered form of programmed cell death, which has a close relationship with infectious diseases and spontaneous inflammatory disease and autoimmune disease.Gasdermin-D is the effector of pyroptosis.Inflammatory caspases cleave Gasdermin-D, break the structural autoinhibition and active the pore-forming activity of Gasdermin-D.Gasdermin-D-N domain is the active form of Gasdermin-D.Oligomerized Gasdermin-D-N domain forms membrane pores.Both pyroptosis and necroptosis can form pores.In this article, the progress of the research on pyroptosis, the involvement of Gasdermin-D in the molecular mechanism of pyroptosis, the distinguishment of pyroptosis from necroptosis and pyroptosis-related diseases are reviewed.

Objective To investigate the intervention of Chinese herb Shengjiang San(SJS)for the imbal-ances of serum Th1/Th2 cells and related regulatory factors in sepsis patients. Methods Fifty-five sepsis patients were randomly divided into two groups:conventional treatment group of 27 cases and SJS group of 28 cases. Nine cases of healthy volunteers were enrolled as control group in the study. Cases of conventional group were treated with western medicine only and cases of SJS group were treated with both western medicine and Chinese herb SJS (100 mL twice one day). The therapy course of both groups was 3 days. Score of Chinese medical syndromes ,se-rum level of leukocyte count,C reactive protein(CRP)and procalcitonin(PCT),serum T-bet,GATA-3,Th1&Th2 cells in the proportion of whole CD4+Th cells and Th1/Th2 ratio were compared respectively in each group be-fore and after treatment. Results There were significant differences between SJS group and conventional group in score of Chinese medical syndromes,serum level of leukocyte count,T-bet,GATA-3,Th1&Th2 cells in the pro-portion of whole CD4+Th cells and Th1/Th2 ratio(P<0.05 or P<0.01). There were no significant differences be-tween the two groups in serum level of CRP,PCT and GATA3. Compared with control group,there were signifi-cant differences in all indicators except GATA3 of the two groups(P<0.01).

OBJECTIVETo compare clinical outcomes of bilateral transpedicular balloon kyphoplasty for the treatment of ordinary osteoporotic vertebral compressive fracture (OVCF) and severe osteoporotic vertebral compressive fracture.

METHODSFrom Junary 2009 to Febuary 2011, 60 patients (70 vertebrae) with osteoporotic vertebral compressive fracture were included. All patients were treated by bilateral transpedicular balloon kyphoplasty combined with postural reduction, including 10 males and 50 females aged from 59 to 90 years old with an average of 72.1 years old. In ordinary osteoporotic vertebral compressive fracture group, there were 38 patients (44 vertebrae) including 7 males and 31 females aged from 59 to 87 years old with an average of (71.8±6.1) years old. There were 6 patients with two vertebral fractures, 1 vertebra in T9, 5 vertebrae in T10, 7 vertebrae in T11, 13 vertebrae in T12, 9 vertebrae in L1, 4 vertebrae in L2, 4 vertebrae in L3, 1 vertebra in L4. While in severe osteoporotic vertebral compressive fracture group, there were 22 patients (26 vertebrae) including 3 males and 19 females aged from 63 to 90 years old with an average of (72.6±7.2) years old. There were 4 patients with two vertebral fractures, 1 vertebra in T9, 2 vertebrae in T10, 3 vertebrae in T11, 9 vertebrae in T12, 6 vertebrae in L1, 3 vertebrae in L2, 2 vertebrae in L3. Operative time, volume of bone cement injection, and vertebral height and changes of Cobb angle before and after operation were observed and compared. Postoperative average recovery rate of vertebral height and correct degree of Cobb angle were caculated and compared, VAS scoring were used to evaluate therapeutic effect.

RESULTSAll operations were completed sucessfully, and pain were relieved at 72 h after operation. All patients were followed up from 6 to 13 months with an average of 10.1 months. Postoperative vertebral height, Cobb angle and VAS score were improved better than that of before operation (P<0.05). Operative time in ordinary group was shorter than severe group, while volume of bone cement injection was more than that of severe group. Average recovery rate of vertebral height and correct degree of Cobb angle in ordinarty group was better than that of in severe group (P<0.05). There was no significant differences between two groups in VAS scores before and after operation (P> 0.05). Three cases (3 vertebrae) ocurred bone cement leakage in ordinarty group, while 5 cases (5 vertebrae) ocurred bone cement leakage in severe group, and there was no meaning between two groups (P>0.05).

CONCLUSIONKyphoplasty could receive satisfied curative effect in treating ordinary and servere patients with osteoporotic vertebral compressive fracture, but recovery of vertebral height and correct degree of Cobb angle in ordinary gourp was better than that of in servere group.

Under the condition of microgravity, human body will experience a series of cardiovascular deconditioning. The vascular endothelial cells are the most important component of the vessel wall, so the changes of biological characteristics of vascular endothelial cells are directly related to cardiovascular deconditioning. Therefore, it is important to prevent and treat the cardiovascular deconditioning in astronauts by studying the effect of microgravity on biological characteristics of vascular endothelial cells.

BACKGROUND: Studies have shown that after bone marrow stem cell transplantation, there are juvenile cells with the episode of myocardial cells around the infarct areas, which was recognized as deriving from bone marrow stem cells.OBJECTIVE: To explore the homing situation of bone marrow stem cells by autologous mobilization around the infarct areas aftar myocardial infarction.DESIGN, TIME AND SETTING: The cytological in vitro study was performed at the China-Japan Clinical Pathology Center, Daliar Medical University from February 2005 to April 2006.MATERIALS: A total of 30 myocardial samples from the autopsy at the Department of Pathology and Forensic Medicine, Dalian Medical University between 2000 and 2005. Fifteen normal samples dyed from the mechanical injuries or craniocerebral injury,without abnormity following autopsy. Fifteen samples in the myocardial infarction group suffered from coronary atherosclerosis and coronary tube stenosis, and died within 10 days after myocardial infarction.METHODS: The autopsy was performed within 48 hours after the death and the tissues were obtained from antedor wall, lateral wall and posterior wall of the left ventricle, and made into tissue sections. We checked the expression of CD34, CD133 and transforming growth factor-β, in the normal area, infarct area and around the infarct area by immunohistochemistry.MAIN OUTCOME MEASURES: The expression of CD34, CD133 and transforming growth factor-β in different areas and the relationship between them.RESULTS: The positive expression of CD34 in infarct area was significantly stronger than that around the infarct area and in normal area (P < 0.01). The positive expression of transforming growth factor-β in infarct area was significantly stronger than that around the infarct area (P < 0.01), and the expression of transforming growth factor-β showed negative reactJon in normal area. The expression of CD34, CD133 and transforming growth factor-β, in infarct areas and around the infarct area was closely related (P < 0.01).CONCLUSION: There are the homing of bone marrow hemopoietic stem cells in infarct area and around the infarct ares after myocardial infarction. The increase in transforming growth factor-β in infarct area provides the possibility for the differentiation of the homing stem cells, the following angiogenesis and the regeneration of cardiomyocytes.
