ABSTRACT

Objective:To analyze the injury characteristics and the burden of disease for developing an injury prevention strategy. Methods:Data derived from the ‘National Injury Monitoring Report Card’ and the Global Burden of Diseases Study 2017(GBD 2017) was analyzed for the relevant indicators including proportion, disability adjusted of life years(DALY), DALY rate,et al. Results:The information of 91 507 cases was analyzed. Male cases were more than the females with sex ratio of 1.5∶1. The highest injury rate (38.1%) was in the group of 25-44 years old. The major career structure was production and transportation (25.5%). The education level of most injured people was middle school. The top two causes of injuries were falls and traffic-related. In 2017, a total of 44 725 people died of injury and the crude death rate of injury was 54.77/105, 64.51/105 in male and 44.85/105 in female. In 2017, the DALY and DALY rate caused by injuries was 217.8 thousand person-years and 2 667.27/105. The top two injuries of DALYs were road traffic accidents and falls, followed by suicide, drowning and mechanical injury. Conclusion:Targeted prevention and control measures for road traffic injury and falls injury should be in place to reduce the burden of injury.

ABSTRACT

Objective To analyze the clustering of major cardiovascular risk factors among population with different level of fasting blood glucose (FBG) in Jiangsu provincial communities. Methods A population-based screening project was conducted during 2015-2017, with 83 522 residents aged 35-75 years from 6 areas included in the study. Prevalence and the clustering of four cardiovascular risk factors (hypertension, obesity, dyslipidemia and smoking) were analyzed. Binary Logistic regression analysis was performed to explore the relationship between FBG and cardiovascular risk factor clustering. Results The prevalence of diabetes was 18.9% among adults aged 35-75 years in Jiangsu province, and 41.4% of them were aware of their disease. Among undiagnosed population, the odd ratios (OR) of cardiovascular risk factors clustering in impaired fasting glucose (IFG) and hyperglycemia group was 1.29 (OR=1.29,95% CI:1.24-1.36,P<0.001) and 1.99 (OR=1.99,95% CI:1.89-2.08,P<0.001), compared with normal FBG group. The control rate of FBG was 15.5% among diagnosed cases. There was no difference in the risk clustering between diabetes patient with and without control of FBG. Conclusions Hyperglycemia and IFG increase the risk of cardiovascular risk factor clustering. Comprehensive interventions should be served as an important role to keep blood glucose at a normal level in high-risk population.

ABSTRACT

With the discovery of the significant medicinal value of alginate oligosaccharides and bioethanol produced by microalgae, alginate lyase has been the focus of research in all fields. Five alginate lyase genes in cluster from Vibrio alginolyticus were cloned and expressed in Escherichia coli. SDS-PAGE and enzyme activity showed that four of the five genes have the activity to degrade alginate. Optimization of the induction conditions, protein purification and enzyme properties of rAlgV3 with the highest enzyme activity were studied. The results showed that the enzyme activity of recombinant enzyme rAlgV3 increased from 2.34×10⁴ U/L to 1.68×10⁵ U/L, which was 7.3 times higher than before. The optimal reaction temperature was 40 °C, and the enzyme was relatively stable between 4 °C and 20 °C. The enzyme had a higher activity between pH 6.5 and 9.0, with the optimum pH 8.0. It showed a wide range of pH that the alginate lyase can exist stably between pH 4.5 and 9.5. Appropriate concentrations of NaCl and Fe²⁺, Fe³⁺ ions promoted enzyme activity. SDS and Cu²⁺ ions inhibited the enzyme activity. The enzyme degraded Poly-M fragments and Poly-G fragments, with a wide range of substrate properties. The degraded product of sodium alginate of rAlgV3 analyzed by ESI-MS mainly was oligosaccharides with a polymerization degree of 2 to 3, which means that rAlgV3 was an endo-type alginate lyase. This enzyme has the potential in the development of third-generation bioethanol and the production of alginate oligosaccharides.

ABSTRACT

Objective@#To evaluate the clinical application of a novel HIV-1 DNA reagent.@*Methods@#HIV-1-infected and non-infected human blood samples were selected, as well as weakly positive samples, indeterminate samples, specific samples. Compared the result of HIV-1 DNA reagent with HIV-1 infection status (refer to the National Guideline for Detection of HIV/AIDS (2015)), the accuracy of the HIV-1 DNA reagent was evaluated in clinical application; Meanwhile, the commercially available RNA quantification kit was selected as reference reagent for parallel detection, and then the consistency and differences were evaluated between HIV-1 DNA reagent and RNA quantification reagent.@*Results@#A total of 95 whole blood samples were tested by the HIV-1 DNA reagent. Taking the HIV-1 infection status as the reference standard, the result showed that the positive agreement rate was 100% (95%CI: 93.94%-100%), the negative agreement rate was 100% (95%CI: 90.26%-100%), and the overall agreement rate was 100% (95%CI: 96.19%-100%). The Kappa value was 1 (95%CI: 1.00-1.00). The HIV-1 DNA reagent could detect weakly positive samples and indeterminate samples of early infection, and could effectively distinguish false-positive samples tested by the Ag-Ab reagent. The specific samples had no false-positive result .@*Conclusions@#The result of HIV-1 DNA reagent were consistent with the HIV-1 infection status. It can be considered as equivalent to the HIV-1 detection reagent commercially available in our country. It can effectively identify the indeterminate samples in the early infection. Compared with the RNA quantification reagent, it can effectively detect HIV-1 DNA of virus reservoirs.

ABSTRACT

<p><b>OBJECTIVE</b>To observe the therapeutic efficacy of Danggui Buxue Decoction No.1 in treating patients of non-small cell lung cancer (NSCLC) at the peri-operational stage and its impact on the patients' immune function.</p><p><b>METHODS</b>Eighty-two NSCLC patients were randomly assigned to two groups equally, the control group and the test group, they were given conventional treatment, while to the test group, DB1 were given additionally. The observation was conducted by testing the changes of T-lymphocyte subsets, natural killer (NK) cell activity, serum levels of immunoglobulin (IgA, IgM, IgG), interleukin-2 (IL-2), tumor necrosis factor alpha (TNF-alpha), cytokeratin fragment 19 (CYFRA21-1) and carcinoembryonic antigen (CEA) in NSCLC patients before and after administration of DB1, and analyzing the patients' general condition.</p><p><b>RESULTS</b>The level of CD3(+), CD4(+), the ratio of CD4 and CD8(+), IgA, IgM, IgG and IL-2 decreased in patients with NSCLC on day 1 after operation, and the level of CD8 and TNF-alpha increased compared to pre-operation. While the levels of CD3(+), CD4(+), CD4 /CD8(+), NK cell activity, serum IgA, IgM, IgG, IL-2 began to elevate, CD8 and TNF-alpha levels began to decline in patients administered with DB1 on day 3 after the operation, earlier than patients who did not use the decoction. The level of CYFRA21-1 and CEA, was immediately decreased after operation in both groups.</p><p><b>CONCLUSIONS</b>Applying DB1 to NSCLC patients at an early post-operational stage could alleviate the impairment and accelerate the recovery of immune function of patients to enhance their immunity. DB1 also shows an anti-tumor action to a certain degree.</p>
