ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the technical characteristics and application of mass casualty incident (MCI) primary triage (PT) methods applied in China.</p><p><b>DATA SOURCES</b>Chinese literature was searched by Chinese Academic Journal Network Publishing Database (founded in June 2014). The English literature was searched by PubMed (MEDLINE) (1950 to June 2014). We also searched Official Websites of Chinese Central Government's (http://www.gov.cn/), National Health and Family Planning Commission of China (http://www.nhfpc.gov.cn/), and China Earthquake Information (http://www.csi.ac.cn/).</p><p><b>STUDY SELECTION</b>We included studies associated with mass casualty events related to China, the PT applied in China, guidelines and standards, and application and development of the carding PT method in China.</p><p><b>RESULTS</b>From 3976 potentially relevant articles, 22 met the inclusion criteria, 20 Chinese, and 2 English. These articles included 13 case reports, 3 retrospective analyses of MCI, two methods introductions, three national or sectoral criteria, and one simulated field testing and validation. There were a total of 19 kinds of MCI PT methods that have been reported in China from 1950 to 2014. In addition, there were 15 kinds of PT methods reported in the literature from the instance of the application.</p><p><b>CONCLUSIONS</b>The national and sectoral current triage criteria are developed mainly for earthquake relief. Classification is not clear. Vague criteria (especially between moderate and severe injuries) operability are not practical. There are no triage methods and research for children and special populations. There is no data and evidence supported triage method. We should revise our existing classification and criteria so it is clearer and easier to be grasped in order to build a real, practical, and efficient PT method.</p>

ABSTRACT

<p><b>BACKGROUND</b>Inflammation plays a pivotal role in the formation and progression of ischemic stroke. Recently, more and more epidemiological studies have focused on the association between C-reactive protein (CRP) -717A > G and -286C > T > A genetic polymorphisms and ischemic stroke. However, the findings of these researches are not conclusive.</p><p><b>METHODS</b>We performed a meta-analysis to determine whether these two polymorphisms are associated with the risk of ischemic stroke. Eligible studies were identified from the database of PubMed, Medline, Embase, Web of Science, CNKI, Weipu, and Wanfang. We calculated odds ratios (ORs) with 95% confidence intervals (CIs) to assess the strength of the association.</p><p><b>RESULTS</b>Four articles were included in our study, including 1926 cases and 2678 controls for -717A > G polymorphism, 652 cases and 1103 controls for -286C > T > A polymorphism. The results of meta-analysis showed that single nucleotide polymorphism (SNP) -717A > G was not significantly associated with the risk of ischemic stroke (GG vs. AA, OR = 1.12, 95% CI = 0.83-1.50, P = 0.207; GG + GA vs. AA, OR = 1.04, 95% CI = 0.93-1.17, P = 0.533; GG vs. GA + AA, OR = 1.10, 95% CI = 0.82-1.47, P = 0.220). Meta-analysis of SNP - 286C > T > A also demonstrated no statistical evidence of a significant association with the risk of ischemic stroke (AA vs. CC, OR = 0.86, 95% CI = 0.59-1.25, P = 0.348; AA vs. CC, OR = 0.92, 95% CI = 0.80-1.06, P = 0.609; AA vs. CC, OR = 0.89, 95% CI = 0.62-1.30, P = 0.374).</p><p><b>CONCLUSIONS</b>This meta-analysis demonstrated little evidence to support a role of CRP gene -717A > G, -286C > T > A polymorphisms in ischemic stroke predisposition. However, to draw comprehensive and more reliable conclusions, further larger studies are needed to validate the association between CRP gene polymorphisms and ischemic stroke in various ethnic groups.</p>

ABSTRACT

BACKGROUND: Earthquakes, floods, droughts, storms, mudslides, landslides, and forest wild fires are serious threats to human lives and properties. The present study aimed to study the environmental characteristics and pathogenic traits, recapitulate experiences, and augment applications of medical reliefs in tropical regions. METHODS: Analysis was made on work and projects of emergency medical rescue, based on information and data collected from 3 emergency medical rescue missions of China International Search and Rescue Team to overseas earthquakes and tsunamis aftermaths in tropical disaster regions Indonesia-Aceh, Indonesia-Yogyakarta, and Haiti-Port au Prince. RESULTS: Shock, infection and heat stroke were frequently encountered in addition to outbreaks of infectious diseases, skin diseases, and diarrhea during post-disaster emergency medical rescue in tropical regions. CONCLUSIONS: High temperature, high humidity, and proliferation of microorganisms and parasites are the characteristics of tropical climate that impose strict requirements on the preparation of rescue work including selective team members suitable for a particular rescue mission and the provisioning of medical equipment and life support materials. The overseas rescue mission itself needs a scientific, efficient, simple workflow for providing efficient emergency medical assistance. Since shock and infection are major tasks in post-disaster treatment of severely injured victims in tropical regions, the prevention and diagnosis of hyperthermia, insect-borne infectious diseases, tropic skin diseases, infectious diarrhea, and pest harms of disaster victims and rescue team staff should be emphasized during the rescue operations.

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the efficacy and safety of alendronate for the treatment of osteoporosis/osteopenia secondary to hyperthyroidism.</p><p><b>METHODS</b>From April 2008 to November 2009, 27 patients with hyperthyroidism with osteoporosis/ osteopenia measured by dual energy X-ray absorptiometry (DXA) were included in this study, and then they were randomly divided into two groups (group A and group B) by simple random sampling. Group A consisted of 14 patients treated with antithyroid drug and caltrate D, the antithyroid drug change with thyroid function, and caltrate D 600 mg per day. Group B consisted of 13 patients treated with antithyroid drug, caltrate D and alendronate, antithyroid drug and caltrate D the same as group A, and alendronate 70 mg weekly. Meanwhile, 21 healthy voluntary adults were chosen as control group. And compared with the control group which was treated with nothing. Followed-up for one year, the bone mineral density (including T-score, Z-score, BMD) in lumbar spine (LS), femoral neck (FN) and distal radius (DR) and general information, were compared before and after treatment.</p><p><b>RESULTS</b>BMD at FN and DR were significantly higher at 12 months after treatment than at the baseline in group A (P = 0.000); T-score, Z-score, and BMD at the LS, FN and DR were all significantly higher at 12 months after treatment than at the baseline in group B (P < 0.05), but these data could not arrive to normal level. In group A, the percentage increased in BMD at the LS, FN, and DR were (4.34 +/- 10.5)%, (3.21 +/- 1.38)%, (1.95 +/- 0.44)%, respectively, at 12 months after treatment. In group B, the percentage increased in BMD at the LS, FN, and DR were (6.10 +/- 8.12)%, (4.10 +/- 5.64)%, (3.10 +/- 3.23)%, respectively, at 12 months after treatment. There was significant difference in the rate of increase between two groups (P < 0.05). AKP decreased, weight, BMI increased, and thyroid function decreased, after treatment than those before in both of the two groups. (P < 0.05).</p><p><b>CONCLUSION</b>Alendronate can significantly increase BMD in treating patients with hyperthyroidism and osteoporosis/osteopenia. Compared with anti-thyroid drugs alone, treatment with alendronate can obtain more clinical effect and also very safety.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To test a nerve bridge substitute for peripheral nerve repair by tissue-engineering approach.</p><p><b>METHODS</b>An artificial nerve fabricated with a scroll of amnion derivative (ZQ membrane) and cultured autogenous Schwann cell was sutured to bridge sciatic nerve defect of 2.5 cm in length in rats. The specimens were assessed with tracking study, histology, electrophysiological technique, NF200, and synaptophysin-38 (SYP) immuno histochemical staining 3 months postoperatively.</p><p><b>RESULTS</b>The regenerated nerve sprouted 3 months after the operation. The regenerated nerve fibers were plentiful and could grow into the recipient nerve and target muscle's motor end plate (MEP) areas to reinnervate target muscle, and reconstruct function of nerve-muscle junction. Functional recovery could reach to 40%-60% of normal control. Nerve-muscle conduction velocity (N-MCV) arrived at 21.77 +/- 1.15 m/s.</p><p><b>CONCLUSIONS</b>A tissue engineering material fabricated with a scroll of ZQ membrane and cultured autologous Schwann cell may be a useful substitute for nerve repair.</p>
