Background:Acute myeloid leukemia (AML) is a common type of hematological malignancy in elderly people.Geriatricians have developed comprehensive geriatric assessment (CGA) methods for elderly patients;however,the tools used for CGA in AML are not uniform.Thus,we aimed to validate the instrumental activities of daily living (IADL) scales,age,comorbidities (Charlson Comorbidity Index),and albumin (IACA) index,which is a new tool for CGA,in elderly patients with AML.Methods:Patients aged ≥60 years who had been diagnosed with AML were screened for eligibility.Among the IACA low-,intermediate-,and high-risk groups,continuous variables were compared using the Mann-Whitney U test,and categorical variables were compared using x2 and Fisher exact tests.In addition,probabilities of overall survival (OS) were estimated using the Kaplan-Meier method.Results:A total of 21,34,and 6 patients were categorized into IACA low-risk (0 point),intermediate-risk (1-2 points),and high-risk (≥3 points) groups,respectively.The rates of relapse/progression-related mortality were 23.8%,58.8%,and 100.0% in the IACA low-,intermediate-,and high-risk groups,respectively (x =12.81,P < 0.001).The 2-year probabilities of OS were 47.7% (95% confidence interval [CI] 22.8%-72.6%) and 20.2% (95% CI 5.9%-34.5%) in the IACA low-and intermediate-risk groups,respectively (x2=5.99,P =0.014),which were significantly higher than those in the high-risk group (low-risk [47.7% (95% CI 22.8%-72.6%)] vs.high-risk [0],x2=20.80,P < 0.001;intermediate-risk [20.2% (95% CI 5.9%-34.5%)] vs.high-risk [0],x2=7.56,P =0.006;respectively).In the IACA low-risk group,the 2-year probability of OS in patients receiving induction chemotherapy (50.8% [95% CI 24.1%-77.5%]) was significantly higher than that in those receiving best supportive care (0,x2=25.74,P< 0.001).Conclusion:We suggest that the IACA index might be a simple and effective tool for comprehensive geriatric assessment in elderly AML patients.

Carotid-cavernous fistulas (CCFs) are abnormal arteriovenous anastamoses between the carotid artery and the cavernous sinus. These fistulas may be classified by cause (spontaneous or traumatic), flow velocity (high or low), or pathogenesis (direct or indirect). The most commonly adopted classification is that described by Barrow based on arterial supply. Traumatic CCFs are almost always direct shunts between the internal carotid artery (ICA) and the cavernous sinus. General features of CCFs, which may be apparent with any lesion, including bruit, headache, loss of vision, altered mental status and neurological deficits. Some fistulae may present primarily with hemorrhage before any evaluation can be performed. However, hemiparesis has been rarely observed. Only a literature review of Murata et al reported a case of hemiparesis caused by posttraumatic CCF, in which the fistula resulted in venous hypertension and subsequent brainstem congestion. While in our case, cerebral infarction was caused by total steal of the blood flow. The patient recovered after occlusion of the fistula with a detachable balloon.

OBJECTIVE:
To explore the distribution of inflammatory cells and positive expression of P-se- lectin glycoprotein ligand-1 (PSGL-1) in infant brainstem tissue from hand-foot-mouth disease related fatal brainstem encephalitis.
METHODS:
Twenty brainstem samples from infants suffered from brainstem en- cephalitis were collected as the experimental group. Ten brainstem samples from infants died of non- brain diseases and injuries were collected as the control group. The distribution of inflammatory cells and the expression of PSGL-1 in the two groups were examined by immunohistochemical method. The characteristics of the positive cells were observed.
RESULTS:
In brainstem tissue of the experimental group, there were sleeve infiltrations of inflammatory cells around the vessels and in the glial nodule. Microglia was the most and following was neutrophils around the vessels and in the glial nodule. There was a significant statistical difference among microglias, neutrophils and lymphocytes (P < 0.05). There was no sleeve infiltration in the control group. PSGL-1 protein was expressed widely in inflammatory cells in the experimental group, especially in the inflammatory cells around the vessels and in the glial nodule. But PSGL-1 positive staining could be observed significantly less in the control group comparing with the experimental group (P < 0.05).
CONCLUSION
Microglia is the main type of inflammatory cells involved in the progress of the fatal disease. Moreover, PSGL-1 could participate in the pathogenesis of hand-foot-mouth disease related fatal brainstem encephalitis.

Objective: To evaluate the prognostic significance of comprehensive geriatric assessment (CGA) in Chinese elderly acute myeloid leukemia (AML) patients. Methods: 73 AML patients over the age of 60 were enrolled. CGA stratification included the following 3 instrument assessment: activity of daily living (ADL) ; instrumental activity of daily living (IADL) ; comorbidity score according to the Modified cumulative illness rating score for geriatrics (MCIRS-G) . According to CGA and age, the enrolled patients were grouped into 'fit', 'unfit' and 'frail' categories. Results: The median age of 73 elderly AML patients were 75 years old. According to CGA, 37 (50.1%) patients were classified as 'fit', 14 (19.2%) as 'unfit', and 22 (30.7%) as 'frail'. 33 (89.2%) patients in fit group received induction chemotherapy, or demethylation treatment, as 8 (57.9%) in unfit, 10 (45.5%) in frail. The overall response rate was 68.7%、62.5%, 75.0% in fit, unfit, and frail group, respectively (χ(2)=0.615, P=0.769) .The early mortality (8 weeks) in three groups were different: 5.4%, 7.1%, 27.3%, respectively (P<0.05) . The 1-year overall survival in the 'fit', 'unfit' and 'frail' groups was 64.9%, 28.6% and 22.7%, respectively (P<0.05) . The CGA score, age, ECOG score, WHO classification (2016) were the prognostic factors of AML patients. Conclusion: CGA can be used to determine the prognosis of elderly AML patients.

AIMTo explore the effects of calcitonin-gene-related peptide (CGRP) on LPS-induced MMP-9 secretion by alveolar macrophages (AM) in vitro.
METHODSThe supernatant of LPS-induced Wistar rat AM from different intervention groups were collected to measure the activity by gelatin zymography.
RESULTS(Only secreting a small amount of MMP-9 with unstimulated AM, LPS stimulated MMP-9 production in a concentration-dependent manner (p < 0.01). (2) The activity of MMP-9 in CGRP intervention groups at different levels were significantly lower than those in non-intervention group (p < 0.01). (3) The inhibiting effects of CGRP were diminished by H-7 and W-7, an antagonist of protein kinase C (PKC) and calmodulin (CaM) (p < 0.05).
CONCLUSIONThese data suggested that CGRP involved in the MMP-9 secretion by AM, partly, via PKC and CaM pathway.

The hybrid xylanase TB was constructed by the substitution of the N-terminus segment of the Streptomyces olivaceoviridis xylanase XYNB with corresponding region of Thermomonosporafusca xylanase TfxA. The hybrid gene tb, encoding the TB, was correctly expressed in Escherichia coli BL21 and Pichia pastoris GS115. TB was purified and its enzymatic properties were determined. The results revealed that the optimal temperature and optimal pH of TB were at 70 degrees C and 6.0, which have been obviously improved compared with those of XYNB. The thermostability of TB were all about six-fold of XYNB's after incubating the properly diluted enzyme solutions at 80 degrees C and 90 degrees C for 3min, respectively. The pH stability of TB was 5 to approximately 9, which was narrower than that of XYNB. Still, TB remains a high specific activity as XYNB does. Analysis of a homology modeling and sequence similarity were used to reveal the factors influencing the enzymatic properties of TB and the discussion for the relationship between structure and function of xylanase was given.
