1.Phosphoglycerate mutase 5 and necroptosis
Chinese Journal of Pathophysiology 2016;32(2):377-380
Necroptosis, or programmed cell death, is a type of cell death with a controllable death signaling pathway and the morphological features similar to necrosis.It is mainly mediated by death receptors or pathogen pattern re-cognition receptors.Among them, tumor necrosis factor receptor 1 (TNFR1)-mediated necroptosis is the most well-studied one.Receptor-interacting protein kinase 1 (RIPK1) and receptor-interacting protein kinase 3 (RIPK3) are the 2 key kina-ses involved in the formation of complex I & II and necrosome in the process of necroptosis.Phosphoglycerate mutase 5 ( PGAM5) , a member of phosphoglycerate mutase gene family, lacks PGAM activity and possesses the phosphatase activi-ty.PGAM5 is anchored in the mitochondrial membrane and is also called mitochondrial phosphoglycerate mutase 5.It has been shown that PGAM5 involves in the formation of necrosome during necroptosis and it is able to accelerate the fission of mitochondria by dephosphorylation of dynamin-related protein 1 (DRP1), thus promoting cell necroptosis.

OBJECTIVE To study the drug resistance of Stenotrophomonas maltophilia in order to direct clinical drug application.METHODS The S.maltophilia was identified and its sensitivity was analyzed with VITEK2-AMS.The extended-spectrum beta-lactamases(ESBLs) and metallo ?-lactamase(MBL) were screened by double-disk synergy test and double-disk confirmatory test.RESULTS The resistance rate of S.maltophilia to cefoperazone-sulbactam,levofloxacin and SMZ-TMP was the lowest,accounted for 12.50%,13.64% and 14.77%,respectively.The ESBLs positive rate was 69.32%,the MBL positive rate was 69.32%.CONCLUSIONS The multidrug resistance of S.maltophilia is serious and full dose use of two or more antibacterials is recommended.

Objective Through the study of medical services cost accounting , we want to find the laws and provide a theoretical basis for government departments to develop standards of medical service prices and control health care costs . Methods On the basis of department cost accounting, we use financial accounting software, to provide medical service items for collection and sharing in accordance with the project income ratio , workload standards.Results Dialysis the three costs dominate factors, the proportion of disposable materials (60.03%)is the key factor affecting the cost.Conclusion Hygiene material spending accounted for a larger proportion of total expenditure , in order to effectively control the medical expense in dialysis patients, efforts should be made to reduce the cost of hemodialysis consumables.

Background Coronary slow flow(CSF)phenomenon is characterized by delayed opacification of coronary vessels in normal coronary angiogram.Although clinical and pathological features have been previously described,its pathogenesis remains unclear.Objective To explore the risk factors related to coronary slow flow.Methods Thirty three patients with documented coronary slow flow which were defined according to TIMI frame count method(TFC)and 33 patients with normal coronary flow were enrolled.Clinical data and biochemical parameters were determined.Results Baseline data analysis showed that CSF group had higher baseline level of platelets count [(149.2?41.5)?109 vs(128.1?38.7)?109,P=0.037] and serum uric acid [(328.1?85.2)vs(282.8?82.4)?mol/L,P=0.032],while other variables were similar between the two groups.After adjustment for BMI,total cholesterol,urea,logistic regression showed that blood platelets count(?2=8.350,?=0.026,P=0.004),2-hour postprandial blood glucose(?2=4.920,?=0.289,P=0.026)and serum uric acid level(?2=5.305,?=0.009,P=0.021)were independent predictors for CSF.Conclusion These data suggest that elevated blood platelets count,2-hour postprandial blood glucose and serum uric acid level may predisposed to coronary slow flow.

Objective To explore the effect of xanthine oxidase inhibitors allopurinol on collagen remodeling of non-infarcted myocardium after myocardial infarction in rats.Methods Myocardial infarction models were produced by ligation of anterior descending coronary artery.The survivals were randomly divided into 3 groups:sham operation group, MI group and allopurinol group(50 mg/kg).On the 7th, 14th, 21st and 28th day respectively, the collagen content were examined. The type Ⅰ and type Ⅲ collagen volume fraction(CVF) and Ⅰ/Ⅲ ratio in non-infarcted zones(NIZ) were examined with PSR staining, mRNA expressions were detected with RT-PCR, the activities of xanthine oxidase(XO) and O—?2,?OH-scavenging in NIZ were examined by colorimetry.In addition, the expression of XO protein by Western blotting analysis and pathological change in LV were detected on the 28th day.ResultsCompared with sham group,the mRNA expressions, CVF of typeⅠand type Ⅲ collagen in NIZ were increased in MI group.The typeⅠ/Ⅲ ratio in NIZ was increased after decreased.The collagen content and activity of XO were boosted but the activities of O—?2,?OH-scavenging were decreased(P

Objective To explore the effect of xanthine oxidase inhibitor allopurinol on cardiomyocyte apoptosis in rats after myocardial infarction(MI).Methods MI model was established by the ligation of anterior descending coronary artery.The survivors were randomly divided into 3 groups: sham operation group(n=5),MI group(n=16) and allopurinol group(n=15,receiving allopurinol 50 mg?kg-1? d-1).After 28 days,the infarct size was measured.In non-infarcted zone(NIZ),cardiomyocyte apoptosis was detected by TUNEL;the expression of Fas was detected by immunohistochemistry;the expressions of xanthine oxidase(XO) and caspase 3 were detected by Western blot.In addition,the activities of XO and ?O-2,?OH-scavenging in NIZ were detected by colorimetry.Results Compared with sham operation group,the apoptosis index and expressions of Fas,XO,caspase 3 in NIZ were significantly increased in MI group.The activity of XO was increased but the activities of ?O-2 and ?OH-scavenging were decreased(P0.05).Conclusion Allopurinol could inhibit the cardiomyocyte apoptosis in NIZ in rats.The protective mechanism of allopurinol involves the reduction of reactive oxygen species and depression of the expressions of Fas and caspase 3.

Objective To learn the plague's host animals and parasitic flea composition, and to investigate the natural foci of plague in Xiji county in order to provide basic information for plague prevention and control. Methods The Citellus alaschanicus density, nocturnal rodents, the body flea, the burrow track flea, the nest flea were investigated in 8 townships (town) of Xiji county from June 11 2007 to July 25 2007. Specimens of small mammalian, fleas were collected for bacteriological and serological testing. Results The average density of the main host Citellus alaschanicus was 0.85 per hectare. The nocturnal mouse capture rate was 0.80%(24/2987).The survey found 16 species of small mammals that belonging to 3 orders, 9 families and 16 species with Citellus alaschanicus the dominant species. The Citellus alaschanicus had 2.84 fleas per body. Four families and 16 species of fleas were identified in the areas. The Citellus alaschanicus and Citellophilus Tesquorum Mongolicus were the dominant species. Plague bacteriology and serology tests were negative. Conclusions The study shows that the area is suitable for the formation of natural foci of Citellus alaschanicus plague. Surveillance is an important measure for prevention and control of the plague.
