Nonlinear and nonparametric causal relationship between financial inclusion and sustainable environment in South Asia.

This study analyzes the causal connection between financial inclusion and carbon emission in selected South Asian countries through a quantile technique-based linear Granger and non-parametric causality test. The analysis of the study covers quarterly data from 1980 Q1 to 2019 Q4. However, the linear Granger causality assessment outcome does not indicate any causal relationship between financial inclusion and carbon emission. In contrast, results from non-parametric assessment reveal a non-linear connection between the variables. The non-parametric test results of the South Asian countries exhibit that financial inclusion leads to carbon emission, which instigates the deterioration of the environment, except for Bhutan. Subsequently, creating awareness by promoting renewable energy resources is essential while investing in fuel-efficient technology to reduce the dependence on fossil fuels. The results of this study provide significant information to the governments and policymakers in emerging countries to improve financial literacy among people to reduce the risk of global warming by encouraging investment in energy-efficient resources.

Exploration and research of community management model for asthmatic children / 中华儿科杂志

<p><b>OBJECTIVE</b>To study the efficacy of community management model of bronchial asthma in children.</p><p><b>METHOD</b>Through community outreach and clinic, 120 cases of children with asthma were enrolled from the 11 000 children aged 0 to 14 in Zhanlanlu area, and a community management model of asthma was established according to the Global Initiative for Asthma requirements combined with the actual situation of the community, both physicians and patients participated in case identification, file creation, and long-term standardized management. Through repeated medical education, the telephone hotline and interactive network of asthma among physicians, children and parents, a physician-patient relationship was established. The data of standardized medication, scheduled re-visit to the hospital, frequency of asthma attacks, antibiotic use, medical expenses, the loss of parents work hours etc. before and after the implementation of community management model were analyzed and compared.</p><p><b>RESULT</b>After implementation of community management model, the use of systemic corticosteroids (19.4%), oral medication (31.6%) was significantly lower than those before implementation (68.3% and 90.0%) (χ(2) = 51.9, 41.1, P < 0.01), use of inhaled corticosteroids (76.5%) and oral leukotriene receptor antagonist (79.6%) was significantly higher compared with control and before management level (10.0%), χ(2) = 106.0, P < 0.01. The days of attacks of asthma (4.6 ± 2.3), the use of antibiotics (16.2 ± 6.1), (5.7 ± 2.9) and the cost of treatment significantly decreased. In 16 cases (13.3%) two-way referral was applied. In this study, the dropout rate was 18.3%, by telephone and network supervision of lost cases, re-education, made some children return to management, eventually the dropout rate was 9.2%.</p><p><b>CONCLUSION</b>Enrollment of children with bronchial asthma into community management model made the children adhere to the management regularly and a standardized management was achieved.</p>

Cloning and Expression of the Full-length cDNAs Encoding Human Class Ⅰ Alcohol Dehydrogenases / 现代生物医学进展

Background & Objective:Background &Objective: The class Ⅰ Alcohol Dehydrogenases (ADH) play a key role in hepatic alcohol catabolism. Human ADH is encoded by at least seven genes, and three class Ⅰ ADH genes-ADH1, ADH2 and ADH3, which encode the α, β, and γ subunit respectively, had been isolated and mapped on chromosome 4q21-q25. This experiment tends to clone the human class Ⅰ ADH and investigate its role in the hepatic alcohol catabolism. Methods: A pair of primers were designed and the full-length cDNAs encoding human Class Ⅰ ADH were cloned at one time. Class Ⅰ ADH cDNAs were amplified with RT-PCR from total RNA extracted from fetal human liver and kidney, and cloned into pGEM-T vector. To identify cDNA segments, a pair of differential primers was designed. By using them, a portion of the ADHs which encodes the segment from -4 to 296 was cloned. These cDNA segments then were detected directly when being digested with Kpn Ⅰ and Pst Ⅰ, respectively. Then all the full-length cDNAs were subcloned in the plasmid pTYB11 and expressed in E. Coli. Stably. Alcohol Dehydrogenase activity of catalyzing alcohol were monitored at 340 nm. Results: Here we had successfully the human class Ⅰ ADH cloned and the full-length cDNAs expressed in E.col.I stably. The relative activity of recombinant enzymes metabolizing ethanol was 0.81 ～1.31 U/mg,0.09 ～0.15 U/mg and 0.76～1.11 U/mg, respectively. Conclusions: In the paper, the full-length cDNAs encoding human class Ⅰ AD H were successfully cloned and expressed and the recombinant enzymes showed the activities similar to the ones isolated from liver.

Analysis of genetic diversity in certified Radix Gentianae by RAPD and ISSR / 中草药

Objective To analyze the sibling relationship and genetic diversity of four certified Radix Gentianae (RG) species by RAPD and ISSR methods. It provided molecular biological proof for species identification and breeding of certified RG. Methods PCR reaction systems of RAPD and ISSR were optimized, and the agarose gel electrophoresis results were analyzed into statistic data. Results Ten RAPD primers and four ISSR primers were selected respectively from 100 RAPD primers and 32 ISSR primers. The statistic data were analyzed to construct cluster analysis dendrogram by genetic distance UPGMA method. Conclusion The PCR reaction systems of this experiment gets ideal RAPD and ISSR results that suit to the analysis of certified RG species in genetic diversity and sibling relationship.
