Neuropathological, clinical epidemiology and animal models studies provide clear evidence for the activation of neuroinflammation in Alzheimer's disease (AD), and long-term use of non-steroidal anti-inflammatory drugs (NSAIDs) is linked with reduced risk to develop the disease. But the clinical trials got a negative outcome with traditional NSAIDs treating AD. The therapeutic effects of NSAIDs on Alzheimer's disease are still not clear based on the present research. Profound study for anti-inflammatory mechanisms and standardized clinical trials are needed. As cause and effect relationships between neuroinflammation and AD are being worked out, the challenge is how to realize the effect of traditional NSAIDs on treating AD.

Abstract: At present, nucleic acid detection technology based on the PCR principle is commonly used to detect malaria parasites, the existing Plasmodium detection methods mainly include microscopy, antigen immunoassay, and nucleic acid detection,but due to the long detection time, high personnel and equipment requirements, and other shortcomings, its popularization, and application at the grassroots level are limited. What challenges previous Plasmodium detection methods are the lack of experienced professionals and advanced equipment at the grassroots as well as the requirement of rapid detection of large samples under extreme conditions. The isothermal amplification technology developed in recent years has potential application prospects due to its simplicity, rapidity, high sensitivity, and high specificity. This article attempts to review the principles, characteristics, and prospects of various isothermal amplification technologies, and on this basis, focuses on the introduction of recombinase polymerase amplification (RPA) and recombinase⁃aided isothermal amplification (RAA) assay technologies and proposes the use of such recombinant enzyme amplification technologies to achieve rapid and accurate diagnosis of common Plasmodium species possibility and imagination.

Objective To determine the relationship between abnormal blood glucose and lipid levels and body mass index in patients with chronic respiratory diseases. Methods This research was conducted in Urumqi baseline survey population from "Xinjiang multi-ethnic cohort study" in which patients with chronic bronchitis, emphysema and chronic obstructive pulmonary disease (COPD) were screened.The patients were defined as angular, normal, overweight, obesity groups according to body mass index (BMI), and were compared with blood levels of lipid and glucose, and rate of abnormal metabolism. Results A total of 6 046 subjects were included in the 2018 Urumqi cohort study, including 545 patients with chronic respiratory diseases.The prevalence of chronic respiratory diseases in different age groups and at different physical activity levels was different, and the prevalence of emaciation group was significantly higher than that of the other three groups.However, there were no statistically significant differences among people with different genders, nationalities, educational levels and whether they smoked or not.There were statistically significant differences in fasting glucose, serum cholesterol (TC) and serum high-density lipoprotein (HDL) levels among respiratory patients with different BMI (P < 0.05).The detection rates of hyperglycemia, high TG and low HDL increased with the increase of BMI.The result of multi-factor analysis showed that blood glucose, TG and HDL were the influencing factors of BMI. Conclusion Increase of body mass index in patients with chronic respiratory diseases is associated with abnormal glucose and lipid metabolism, which is not significantly different from that in patients with non-respiratory diseases.However, the body mass index and nutritional status of patients with long-term diseases should be closely monitored, and timely intervention measures should be taken to delay the disease process.

OBJECTIVETo observe the effect platelet antigen modification by mPEG-SPA with different molecular masses.

METHODSPlatelet CD42a was modified by 5 kD and 20 kD mPEG-SPA, respectively, and the fluorescence intensity of CD42a was detect by flow cytometry and the three-dimensional structure of CD42a simulated to analyze the distribution of lysine in CD42a molecule.

RESULTSAfter platelet CD42a modification by 5 kD and 20 kD mPEG-SPA, the fluorescence intensity of CD42a decreased sharply by 85.54% and 88.65%, respectively, and multiple lysine regions were identified on the surface of CD42a molecule.

CONCLUSIONBoth 5 kD and 20 kD mPEG-SPA allow useful modification of platelet CD42a, but 20 kD mPEG-SPA is more advantageous than 5 kD mPEG-SPA.

BACKGROUNDDonor and recipient risk factors on graft function have been well characterized. The contribution of demographic factors, such as age, gender, and other potential factors of donor and recipient at the time of transplantation on the function of a graft is much less well understood. In this study, we analyzed the effects of factors such as age, gender, etc., on the short-term and long-term graft function in kidney transplant recipients from living donor.

METHODSA total of 335 living donors and their recipients, who had kidney transplantation in our center from May 2004 to December 2009, were included. Serum creatinine level was used as the assessment criterion (serum creatinine level lower than 115 mmol/L is normal). Factors related to graft function such as age, gender, blood relation by consanguinity, human leukocyte antigen (HLA) mismatch, ABO type, etc., were analyzed separately.

RESULTSDonor age is the key factor affecting both the short-term and long-term function of a grafted kidney from a living donor. The group with donors younger than 48 years showed the best kidney function post transplantation. Match of gender and age is another important factor that influences the function of grafted kidney from a living donor. The older donor to younger recipient group had the worst outcome after kidney transplantation. After 36 months post transplantation, female donor to male recipient group had worse kidney function compared to other groups. We also found that calcinerin inhibitor used in the maintenance period may influence the function of a grafted kidney. No significant statistical differences were found in consanguinity, blood type, and mismatch of HLA.

CONCLUSIONSDonor age is an important factor affecting the function of a grafted kidney from a living donor. We also recommend taking nephron, immunology factor, infection, and demographic information all into consideration when assessing the outcome of kidney transplantation.

We examined the effects of conjugated linoleic acid (CLA) on growth, fatty acid composition and enzyme activity of fatty acid oxidation in the liver of large yellow croaker. We divided 1600 fish (average initial weight 150 g) into 4 groups and reared them in 8 cages. Four dietary treatments were formulated to contain 0%, 1%, 2% and 4% (w/w) CLA, respectively. The fish were fed for 10 weeks ad libitum twice daily. We found that the dietary CLA had no effect on growth, biometric parameters and whole body proximate (P>0.05), but showed some significant effects on the fatty acid composition in both muscle and the liver. The activities of lipogenic enzymes were slightly depressed in fish fed with increasing levels of CLA when compared with control (P>0.05). Dietary CLA supplementation had no effects on liver lipid content, but significantly increased the contents of saturated fatty acids (SFA) and polyunsaturated fatty acids (PUFA) (P<0.05) and decreased monounsaturated fatty acid (MUFA) content in both muscle and the liver. Dietary CLA inclusion resulted in significant increases of the biologically active cis-9, trans-11 and trans-10, cis-12 isomers in both tissues (P<0.05). The total accumulation of CLA was higher in the liver (3.83%, w/w) than in muscle (3.77%, w/w) when fed with 4% (w/w) CLA. This study demonstrates that large yellow croakers are capable of absorbing and depositing CLA and long-chain n-3 PUFA in the liver and muscle, showing that this species fed with CLA could be an important human food source for these healthful fatty acids.

The aim of the study is to investigate the effect of salvianolic acid B (SalB) on blood-brain barrier (BBB) in rats after cerebral ischemia-reperfusion, and to illustrate its possible mechanisms. Cerebral ischemia-reperfusion was induced by middle cerebral artery occlusion in rats. The break-down of BBB was indicated by extravasations of immunoglobulin (IgG) monitored with immunohistochemistry. The expression of MMP-9 and NOS2 in the brain was determined by immunohistochemistry, and the expression of p-p38 and p-ERK1/2 was detected by Western blotting. It was shown that on day 2 after ischemia-reperfusion the IgG accumulated around the vascular boundary zone, suggesting the break-down of BBB, and the expression of MMP-9 and NOS2 up-regulated at the same time. The result of Western blotting suggested that the expression of p-p38 and p-ERK1/2 increased. On day 7 after ischemia-reperfusion the. expression of MMP-9 and NOS2 was about the same level as day 2, the expression of p-p38 was higher than that on day 2 and the expression of p-ERK1/2 was slightly lower than that on day 2. SalB (1 and 10 mg x kg(-1)) significantly alleviated the extravasations of immunoglobulin induced by cerebral ischemia-reperfusion (P < 0.05). On day 2 and day 7 SalB attenuated the expression of MMP-9 and NOS2 (P < 0.05). SalB (10 mg x kg(-1)) reduced the expression of p-p38 and p-ERK1/2 apparently on day 2 and 7 after ischemia-reperfusion (P < 0.05). SalB (1 mg x kg(-1)) inhibited the expression of p-p38 on day 7 after ischemia-reperfusion (P < 0.05). The results indicate that SalB protects blood-brain barrier in rats after cerebral ischemia-reperfusion by inhibiting the MAPK pathway.

OBJECTIVETo investigate the clinical characteristics of anti-HBc IgM positive chronic hepatitis B patients and the relation of anti-HBc IgM development to serum HBV DNA load and the state of HBeAg/anti-HBe.

METHODSThe clinical data were collected from patients with chronic hepatitis B hospitalized in the Infectious Diseases Hospital, Zhangjiakou city, and in Ditan Hospital, some of whom were anti-HBc IgM positive and some others were negative. Their HBV DNA load was examined by real-time PCR, and HBeAg/anti-HBe was detected by AXSYM auto-enzyme analyzer with the third generation EIA regent.

RESULTSTotally 200 patients were enrolled in this study. The number of patients with mild, moderate and severe hepatitis was 71, 83 and 46. The anti-HBc IgM positive patients were older and had longer course of disease than those of anti-HBc IgM negative patients. Of the anti-HBc IgM positive group, 45.71 percent and 54.29 percent had mild and moderate hepatitis, which were significantly different from those in the anti-HBc IgM negative patients (30.00 percent and 70.00 percent). But there was no difference between anti-HBc IgM positive and negative patients in serum HBV DNA level, the state of HBeAg/anti-HBe and outcome.

CONCLUSIONThe anti-HBc IgM state of chronic hepatitis B patients was related to the severity of hepatitis, but not with virus load and state of HBeAg/anti-HBe.
