Objective To explore whether metformin preconditioning can protect brain injury after cardiac arrest/cardiopulmonary resuscitation(CA/CPR)and its possible mechanisms and signaling pathways.Methods Constructed a CA model by using electrical stimulation.Rats were randomly divided into the sham group(0.9%NaCl gavage daily for 14 days,without inducing CA),model group(CA model was induced after 0.9%NaCl gavage daily for 14 days),experimental group(CA model was induced after 200 mg·kg-1 Met+0.9%NaCl gavage daily for 14 days),Cc group[200 mg·kg-1 Met+0.9%NaCl gavage daily for 14 days,adenosine 5'-monophosphate kinase-activated protein(AMPK)inhibitor Compoud C(Cc)was injected intraperitoneally at 1 hour before modeling],chloroquine(CQ)group(daily 200 mg·kg-1 Met+0.9%NaCl gavage for 14 days,intraperitoneal injection of autophagy inhibitor CQ at 1 hour before modeling)and AICAR group(continuous daily 200 mg·kg-1 Met+0.9%NaCl gavage for 14 days,intraperitoneal injection of AMPK agonist AICAR at 1 hour before modeling).The 7-day survival rate after CA/CPR via using survival curves was recorded;the neurological function 7-days after CA/CPR was scored by using the neurological disability scale;the protein malondialdehyde(MDA)level were measured using the Coomassie Brilliant Blue method;detection of reactive oxygen species(ROS)levels in brain tissue by using ROS fluorescent probe DHE;Western blotting was used to determine the expression levels of related proteins such as AMPK,p-AMPK,microtubule associated protein 1 light chain 3 Ⅰ(LC3 Ⅰ),LC3 Ⅱ,and p62 in brain tissue.Results The 7-day survival rates of sham,model,experimental,Cc,CQ and AICAR groups rats were 100%,40%,70%,40%,40%and 65%,respectively;the 7-day neurological function scores were 78.35±1.65,46.50±4.41,67.93±4.64,49.50±3.53,52.00±2.83 and 68.33±1.53,respectively;the ROS levels were(417.60±8.37),(748.60±36.05),(575.80±10.73),(713.80±18.85),(668.20±9.58)and(566.00±24.48)U·mg-1,respectively;the MDA levels were(4.38±0.33),(8.06±0.76),(5.50±0.48),(7.18±0.29),(6.82±0.31)and(5.20±0.34)nmol·mg-1,respectively;the brain tissue p-AMPK/AMPK were 0.74±0.04,0.87±0.01,1.61±0.01,0.55±0.05,1.09±0.09 and 1.27±0.07,respectively;the p62 values were 0.42±0.02,0.86±0.05,0.61±0.04,0.98±0.04 and 0.78±0.03,respectively;the LC3 Ⅱ/LC3 1 were 0.29±0.32,0.37±0.26,0.96±0.78,0.58±0.26,0.43±0.03 and 1.40±0.10,respectively.Compared with the model group,the differences of above indexes in the experimental group,AICAR group were statistically significant(all P<0.05);compared with the experimental group,the differences of above indexes in the Cc group,CQ group were statistically significant(all P<0.05).Conclusion Metformin preconditioning can play a protective role in brain injury after cardiac arrest/cardiopulmonary resuscitationin in rats by activating the AMPK signaling pathway,regulating mitochondrial energy metabolism and promoting autophagy.
2.Understanding Taiwanese Women's Decisional Experiences Regarding Prenatal Screening Procedures And Diagnostics: A Phenomenological Study
Asian Nursing Research 2020;14(4):231-240
Purpose:
This study sought to understand Taiwanese women’s decisional experiences regarding prenatal screening procedures and diagnostics.
Methods:
A hermeneutic phenomenological design guided semistructured interviews with 33 women who were 36 weeks pregnant. Data were collected between February and October 2016. Verbatim transcripts were analyzed following hermeneutic circle to cocreate an understanding of Taiwanese women’s decision-making in prenatal screening and diagnostics.
Results:
Women’s existential experiences were derived from their decision-making process on prenatal screening procedures and diagnostics for chromosomal aneuploidy. These decisional experiences were captured by four theme clusters and eight themes, which were inductively derived from 16 meaning units: (1) accessing health information; (2) considering what was best for my baby; (3) considering family finance; and (4) feeling anxiety posttest.
Conclusion
Participants made informed choices on several prenatal screening procedures, ostensibly, based on their personal values and considerations. During the decision-making process, often-cited benefits of genetic screenings were emphasized, but test limitations were often unheeded. A fundamental need for supportive information in decision making was further identified with recommended strategies. Hence, a revision of traditional genetic counseling approaches is recommended. As genomics technologies are increasingly available during antenatal services, women should be sufficiently educated about them to support decision making.

Objective:
To explore the association between soil selenium levels and the risk of diabetes in Chinese adults aged 35-74 years.
Methods:
Data for this study were derived from the China Chronic Diseases and Behavioral Risk Factors Surveillance 2010 survey. Selenium concentrations in soil were obtained from the Atlas of Soil Environmental Background Values in China. A two-level binary logistic regression model was used to determine the association between soil selenium concentrations and the risk of diabetes, with participants nested within districts/counties.
Results:
A total of 69,332 participants aged 35-74 years, from 158 districts/counties were included in the analysis. Concentrations of selenium in soil varied greatly across the 158 districts/counties, with a median concentration of 0.219 mg/kg ( : 0.185-0.248). The results showed that both Quartile 1 (0.119-0.185 mg/kg) and Quartile 4 (0.249-0.344 mg/kg) groups were positively associated with diabetes compared to a soil selenium concentration of 0.186-0.219 mg/kg (Quartile 2), crude odds ratios ( s) (95% ) were 1.227 (1.003-1.502) and 1.280 (1.048-1.563). The values were 0.045 and 0.013, for Quartile 1 and Quartile 4 groups, respectively. After adjusting for all confounding factors of interest, the Quartile 1 group became non-significant, and the Quartile 4 group had an adjusted (95% ) of 1.203 (1.018-1.421) relative to the reference group (Quartile 2), the values was 0.030. No significant results were seen for the Quartile 3 group (0.220-0.248 mg/kg) compared to the reference group.
Conclusion
Excessive selenium concentrations in soil could increase the risk of diabetes among Chinese adults aged 35-74 years.

Except the complete literature of , Tianhui medical slips unearthed in Chengdu also include a part of literature document on meridian, which was seriously damaged. Both of them were found in the same box together with . The title of the document chapter was not found in the residual medical slips. By investigated the textual content, it was discovered that such medical slips were different from the Mawangdui silk books, i.e. and , of Zhangjiashan bamboo slips of Han Dynasty, as well as in Tianhui medical slips. But, the sentences in description are similar to the sentences of in (), therefore, this residual slips was named as () by the collator. In the paper, by the comparison of this residual slip chapter with the unearthed literature document on meridian as well as in , the origin and evolution of meridian theory of traditional Chinese medicine in the Qin and Han dynasties were explained. By taking it as an example, the construction process of classical theory of traditional Chinese medicine was explored.

This study discussed whether the current pharmacokinetic study method of compound Chinese medicine could meet its research ob-jectives in drug development process.The conclusion were that, firstly, because the single or multiple active ingredient often do not represent the true effect of compound Chinese medicine, its findings may be biased. Secondly, drug accumulation method, pharmacological effect method, serum pharmacological method and integration of multi-effect component classifier method often draw pharmacokinetic results by pharmacodynamic study with thrust reversers method, but these methods can not accurately reflect the true pharmacokinetics in vivo.It might be more clinical value to make pharmacodynamic studies with pharmacodynamic markers.

Objective The aim of this study was to demonstrate the immunogenicity and safety of diphtheria, tetanus, pertussis (acellular, component) , poliomyelitis (inactivated) vaccine (adsorbed) and Haemophilus influenzae type b conjugate vaccine (DTaP-IPV//PRP-T) combined vaccine compared with commercially available DTaP (diphtheria, tetanus and pertussis), Haemophilus influenzae type b (Hib), tetanus conjugate and IPV monovalent vaccine. Methods Subjects were randomly divided into three groups, Group A and Group B were DTaP-IPV//PRP-T combined vaccine (PENTAXIMTM) vaccinated at 2,3,4 months of age or 3,4, 5 months of age respectively; Group C was commercially available DTaP. Hib tetanus conjugate (Act-HIBTM) and IPV (IMOVAX PolioTM) vaccines vaccinated at 3,4, 5 months of age. All groups received booster dose at 18 to 20 months of age, with antibody titers tested. Non-inferiority analysis was demonstrated in terms of seroprotection / seroconversion rates between Group A, Group B respectively and Group C. Safety information was collected after each vaccination to assess the safety of investigational vaccines. Results The non-inferiority of DTaP-IPV//PRP-T combined vaccine vaccinated at 2,3,4 or 3,4, 5 months of age versus DTaP, Hib tetanus conjugate and IPV vaccine was demonstrated for all vaccine antigens in both primary and booster phases in terms of seroprotection/seroconversion rates. DTaP-IPV//PRP-T combined vaccine was well tolerated. The rate of solicited/unsoliciated severe adverse reactions was very low and similar to the control vaccines. Conclusion DTaP-IPV//PRP-T combined vaccine was highly immunogenic with good safety profile in Chinese infants, which was comparable to the commercially available control vaccines.

OBJECTIVETo observe and compare the clinical effect of Dingweiban and Xieban manipulation, and to compare the change of the deviation of spinous processes between two methods.
METHODSOne hundred and twenty-two cases were divided into two groups. Sixty-two cases were treated with Dingweiban manipulation method and 60 cases by Xieban manipulation. The changes of Fairbank scores, the clinical effects and the difference of the deviation of the spinous processes (L3, L4, L5) from the lumbar posterior-anterior X-ray were compared.
RESULTSThe scores before and after treatment and 3 months after treatment were compared. There were significant differences between two groups (P < 0.05) by nonparametric test. The result of Dingweiban manipulation group: 53 cases cured, 5 cases better, 3 cases effective and 1 case no effect. The result of clinical Xieban manipulation group: 43 cases cured, 6 cases better, 7 cases effective and 4 cases no effect. The clinical effects had significant differences after treatment and 3 months after treatment (P < 0.05, P < 0.0l) by nonparametric test. After the first treating, there was clear difference of the deviations' distance of the L4 spinous process compared with the Xieban manipulation group (P < 0.05). After the last treating, there were clear differences of the deviation distance of the L4 and L5 spinous processes compared with the Xieban manipulation group (P < 0.05, P < 0.01).
CONCLUSIONDingweiban manipulation is better than Xieban manipulation in effects and has influence on the deviation of spinous processes, especially for the L5 spinous process.
