Objective To evaluate the therapeutic effects of recombinant expression plasmid containing hepatocyte growth factor (HGF) and augmenter of liver regeneration (ALR) on rats with hepatic fibrosis. Methods Ninety Sprague-Dawley rats, which had been established into hepatic fibrosis models, were equally divided into 6 groups: blank group, pcDNA3.1 therapy group,pcDNA3.1-HGF therapy group, pcDNA3. 1-ALR therapy group, pcDNA3.1-HGF and pcDNA3. 1-ALR combined therapy group, and pcDNA3. 1-HGF-ALR therapy group. Zero point one μmol of blank or plasmid was injected into model rats in each group by tail vein once a day for 3 days. Model rats in blank group didn't receive any treatment. Additional 10 rats were chosen as control group, which were not given any interference during the experiment. All rats were sacrificed 4 days after end of treatment. Liver tissues were reserved for observing pathologic changes after HE staining and detecting proliferating cell nuclear antigen (PCNA) and c-jun by immunohistochemistry. Measurement data were compared by single-factor analysis of variance. Comparison between groups was done by SNK test. Enumeration data were analyzed by Fisher's exact test. Results In blank group and pcDNA3.1 therapy group, hyperplasia of fibrous connective tissue was very obvious, false lobules were formed. There was no significant difference between these two groups (x2 =0. 317,P= 1. 000).In the 4 remaining groups, hepatic fibrosis all achieved different degree of amelioration, and the therapeutic effect of pcDNA3.1-HGF-ALR was optimal. In control group, the expressions of PCNA and c-jun in liver tissues were low, with absorbance value of 8.6±1.9 and 3.2 ± 1.2, respectively. In blank group and pcDNA3. 1 therapy group, the expressions of PCNA and c-jun were obviously increased, with absorbance value of 24. 1±3.0, 24.5±4.3 and 23.8±3.1, 24.9±4.2, respectively,which were significant different from control group (all P<0.01). In the 4 remaining groups, the expressions of PCNA were all obviously increased, and expressions of c-jun were all obviously decreased. The maximum change scope was observed in pcDNA3. 1-HGF-ALR therapy group.Conclusions The recombinant expression plasmid pcDNA3. 1-HGF-ALR can effectively ameliorate experimental hepatic fibrosis of rats. The anti-fibrosis effects are achieved probably by up-regulating PCNA expression and down-regulating c-jun expression.

To analyze the association between recombinant solute carrier family 11, member 1 ( SLC11A1 ) rs17235409 polymorphism and treatment failure of pulmonary tuberculosis, so as to provide the basis for the prevention and treatment of pulmonary tuberculosis.
Methods:
The patients with pulmonary tuberculosis registered for treatment at the Urumqi Center for Disease Control and Prevention in 2019 was recruited and collected demographic, clinical and treatment information from National Infectious Diseases Reporting System. The polymorphism of SLC11A1 rs17235409 was detected by multiple ligase chain reaction and Hardy-Weinberg balance test was performed. The multivariate logistic regression analysis was conducted for the association between rs17235409 and the treatment outcome of tuberculosis.
Results:
A total of 731 cases of pulmonary tuberculosis patients were enrolled, and 37 cases failed, with a failure rate of 5.06%. The failure rate of the patients with G/A was 8.55%, with G/G was 4.23%. The results of multivariate logistic regression analysis showed that the patients with G/A were more likely to fail in the treatment than those with G/G ( OR=2.213, 95%CI: 1.041-4.702 ). The males with G/A were more likely to fail in the treatment than those with G/G ( OR=2.547, 95%CI: 1.021-6.356 ).
Conclusion
The rs17235409 polymorphism of SLC11A1 is associated with the failure of tuberculosis treatment, and the patients with G/A are more likely to fail.

Objective To analyze the fetus chromosome abnormalities in women with advanced maternal age under the universal two-child policy. Methods A total of 10607 women underwent prenatal diagnosis proce-dures from the year of 2015 to 2016,among which 3569 cases were with advanced maternal age. Cytogenetic karyotyping was conducted with chromosomal microarray analysis(CMA)in 854 cases. The ration of chromosome abnormalities in the two population groups(aged from 35~39 and over 40)were counted. The type of abnormali-ties were also analyzed. Results The ration of women with advanced maternal age in 10607 cases underwent pre-natal diagnosis between 2015 and 2016 was 33.6%. The respective rations were 27.2%and 37.9%. The detection rates of chromosome abnormalities were 7.9% and 10.8%,with significantly difference. The significant differences were also found in the detection rate of chromosome aneuploidies ,but no differences in other chromosome abnor- malities. CMA was benefit to detect the micro chromosome abnormalities. Conclusions In 2016,the number of prenatal diagnosis procedures increased under the two-child policy. The detection rate of chromosome abnormalities also significantly increased. The incidence of chromosome abnormalities was higher with the growing age of preg-nant women. Genetic counseling must be presented and prenatal diagnosis should be promoted in women with ad-vanced age.
