目的了解广西灵山县2～6岁儿童乙肝疫苗免疫效果,为乙肝病毒(HBV)高流行区乙肝防控提供依据。方法 2016年12月,按照横断面调查研究原理,用整群抽样的方法选取灵山县2～6岁儿童为研究对象,采用问卷调查并采集静脉血3～5 mL,用酶联免疫吸附实验(ELISA)检测HBV血清学标记物。结果调查了1 594名儿童,乙肝疫苗免疫覆盖率为100%;5岁以下儿童HBsAg标准化阳性率为0.17%(3/832,95%CI:-0.11～0.45);抗-HBs标准化阳性率为68.98%(95%CI:66.71～71.25);HBeAg和抗-HBe标准化阳性率分别为0.16%(95%CI:-0.04～0.36)和0.38%(95%CI:0.08～0.68);抗-HBc标准化阳性率为43.97%(95%CI:41.53～46.41)。不同年龄组间抗-HBs阳性率差异有统计学意义(P<0.001),且随着年龄增长而呈下降的趋势(P<0.001)。非条件多因素Logistic回归模型分析结果显示,年龄、城乡分布、低出生体重和分娩医院级别与抗-HBs阳性率有关,加强免疫与低龄儿童抗-HBs阳性率无关。3名HBsAg持续阳性儿童的母亲产检检测HBsAg阳性。结论广西灵山县达到全国乙型病毒性肝炎防治规划的目标(<1%);已经完成乙肝疫苗全程基础免疫的学龄前儿童没必要进行乙肝疫苗加强免疫。

Furthermore, bacterial cooccurrence patterns were significantly influenced by continuouscropping years, with long-term monocropped alfalfa simplifying the complexity of the cooccurrencenetworks. These findings enhanced our understandings and provided references for forecasting howsoil bacterial communities responds to monocropped alfalfa.

The paper aimed to establish a rapid multiplex PCR assay for detection of 1-15, H9 subtype avian influenza virus （VIA） and duck Tembusu virus （DT- MUV）. According to the HA gene sequences of I-L5 and H9 AIV and NS5 gene of DTMUV in C, enBank, three sets of primer specific to these three kinds of viruses were designed, respectively. The multiplex PCR for simultaneous detection of AIV （ HS, H9 ） and DTMUV was established, and was applied in clinical. The speci- ficity and sensitivity of the multiplex PCR were tested. The results showed that the assay could specifically amplify the gene fragments of I-IS AIV （380 bp）, H9 AIV （ 732 bp）, and DTMUV （250 bp ）, and were all negative for other duck viruses. This method showed the sensitivity of 533 pg/μL for H5 MV, 56 pg/μL for I-I9, and 6.6 ng/μL for DTMUV. Additionally, the detection results of 200 clinical samples indicated that this multiplex PCR method was a rapid, sensitive and svecific tool for clinical sample detection.

Background: Severe burns injury is a serious pathology, leading to teratogenicity and significant mortality, and it also has a long-term social impact. The aim of this article is to describe the hospitalized population with severe burns injuries in eight burn centers in China between 2011 and 2015 and to suggest future preventive strategies. Methods: This 5-year retrospective review included all patients with severe burns in a database at eight institutions. The data collected included gender, age, month distribution, etiology, location, presence of inhalation injury, total burn surface area, depth of the burn, the length of hospitalization, and mortality. SPSS 19.0 software was used to analyze the data. Results: A total of 1126 patients were included: 803 (71.3%) male patients and 323 (28.7%) female patients. Scalds were the most common cause of burns (476, 42.27%), followed by fire (457, 40.59%). The extremities were the most frequently affected areas, followed by the trunk. The median length of hospitalization was 30 (15, 52) days. The overall mortality rate was 14.21%. Conclusions: Although medical centers have devoted intensive resources to improving the survival rates of burn patients, expenditures for prevention and education programs are minimal. Our findings suggest that more attention should be paid to the importance of prevention and the reduction of injury severity. This study may contribute to the establishment of a nationwide burn database and the elaboration of strategies to prevent severe burns injury.

[Objectives]To study the content and antidepressant effects of the flavonoids in the Zanthoxylum Pericarpium Residue(ZPR)and to provide a basis for the full utilization of ZPR.[Methods]The method for the assay of total flavonoids in ZPR by UV spectrophotometry was developed with rutin as *** total flavonoids were extracted and separated from *** contents of total flavonoids were quantified in ZPR and its *** autonomous activity test,tail suspension test and forced swimming test were conducted in mice,and the levels of malondialdehyde(MDA),superoxide dismutase(SOD)and total antioxidation were detected to evaluate the antidepressant effects of total flavonoids.[Results]The recovery rate of UV spectrophotometry was 98.88%(n=6).The contents of flavonoids in ZPR and its extract were 11.07%and 78.42%,*** the autonomous activity test,compared with the control group,the standing times of mice in the positive drug group was significantly increased(P0.05),as well as there was no significant difference of the activity times among all groups(P>0.05).In the tail suspension and forced swimming tests,compared with the control group,the immobility time of the high-dose group of total flavonoids extract was significantly reduced(P>0.05),and the serum SOD levels of the low-,medium-and high-dose groups were significantly increased(P<0.05).The MDA levels of the middle-and high-dose groups of total flavonoids were significantly decreased(P<0.05),and the total antioxidant capacity was increased significantly(P<0.05).[Conclusions]The developed UV spectrophotometry can accurately detect the level of total flavonoids in *** is rich in flavonoids,and has significant antidepressant effects,which may be related to eliminating internal free radicals and inhibiting lipid peroxidation.
