Objective To investigate the therapeutic mechanism of Dan Hong in a rat model of cervical spondylotic myelopathy (CSM).Methods Thirty Sprague-Dawley rats were divided into an experimental group (n=10),aCSM modelgroup (n=10),and acontrol group (n=10).The CSM model group received a Dan Hong injection,while the control and experimental groups received an injection of an equivalent volume of physiological saline.The motor function of the rats was assessed before administration and at 4 weeks after administration,at which time the rats were sacrificed.The expression of cytokines and bcl-2 was detected by ELISA and Westem blotting.Results Four weeks after treatment,the number of oblique plates in the experimental group increased.Additionally,the expression of cytokines (IL-6 and TNF-α) in the CSM model group was higher and the expression of bcl-2 was lower.Conclusion Dan Hong injection can reduce the inflammatory response and reduce cell apoptosis in CSM.

Objective:To learn about the cognition of iodine deficiency disorders (IDD) prevention knowledge among key population in the IDD area of Jilin Province, and to evaluate the effect of health education.Methods:From 2015 to 2019, 10 counties (cities, districts, hereinafter referred to as counties) in Jilin Province were selected as project counties every year. Public health education covered the entire project county. In each project county, 3 project townships were selected, and students of grades 4-6 were selected from the central primary schools of each project township for school health education. In each project township, 3 project villages were selected to carry out community health education. Before and after health education, 30 fifth-grade students were selected from the central primary school of each project township, and 15 housewives were selected from the vicinity of each primary school to conduct a questionnaire survey on IDD prevention knowledge.Results:After health education, the overall awareness rate of IDD prevention knowledge among primary school students and housewives in Jilin Province was 96.26% (13 324/13 842) and 96.40% (6 819/7 074), which was significantly higher than that before the intervention [65.36% (9 032/13 818) and 71.26% (5 039/7 071)], and the differences were statistically significant (χ 2 = 4 258.34, 1 647.92, P < 0.001), and the awareness rates of primary school students and housewives increased by 30.90% and 25.14%, respectively. Conclusion:Health education has significantly increased the awareness rate of IDD prevention knowledge among key populations in Jilin Province, and is an important measure to ensure the continuous elimination of IDD.

Objective To investigate the differences and the immunocompatibility of wild-type (WT), four-gene modified (TKO/hCD55) and six-gene modified (TKO/hCD55/hCD46/hTBM) pig erythrocytes with human serum. Methods The blood samples were collected from 20 volunteers with different blood groups. WT, TKO/hCD55, TKO/hCD55/hCD46/hTBM pig erythrocytes, ABO-compatible (ABO-C) and ABO-incompatible (ABO-I) human erythrocytes were exposed to human serum of different blood groups, respectively. The blood agglutination and antigen-antibody binding levels (IgG, IgM) and complement-dependent cytotoxicity were detected. The immunocompatibility of two types of genetically modified pig erythrocytes with human serum was evaluated. Results No significant blood agglutination was observed in the ABO-C group. The blood agglutination levels in the WT and ABO-I groups were higher than those in the TKO/hCD55 and TKO/hCD55/hCD46/hTBM groups (all P<0.001). The level of erythrocyte lysis in the WT group was higher than those in the ABO-C, TKO/hCD55 and TKO/hCD55/hCD46/hTBM groups. The level of erythrocyte lysis in the ABO-I group was higher than those in the TKO/hCD55 and TKO/hCD55/hCD46/hTBM groups (both P<0.01). The pig erythrocyte binding level with IgM and IgG in the TKO/hCD55 group was lower than those in the WT and ABO-I groups. The pig erythrocyte binding level with IgG and IgM in the TKO/hCD55/hCD46/hTBM group was lower than that in the WT group and pig erythrocyte binding level with IgG was lower than that in the ABO-I group (all P<0.05). Conclusions The immunocompatibility of genetically modified pig erythrocytes is better than that of wild-type pigs and close to that of ABO-C pigs. Humanized pig erythrocytes may be considered as a blood source when blood sources are extremely scarce.

Objective To investigate the beneficial effect of Kai-Xin-San combined with fluoxetine in improving depression-like behaviors on chronic unpredictable mild stress(CUMS)induced depression model mice.Methods The present study aimed to assess the potential of Kai-Xin-San in combination with fluoxetine to ameliorate depression-like behaviors in a CUMS induced mouse depression model.Behavioral tests,such as the sucrose preference test were employed to evaluate the efficacy of the treatment.Additionally,the levels of suppressed stress factors were measured using the ELISA method.The morphology of hippocampal tissue was evaluated using the HE staining method,Nissl Staining and TUNEL staining methods.Furthermore,western blotting analysis was utilized to determine the expression levels of proteins such as Caspase-3,and Caspase-9.Results The co-administration of Kai-Xin-San and fluoxetine resulted in a significant increase in sucrose preference rate in model mice.This effect was comparable to that of fluoxetine alone at the standard clinical dose.Furthermore,the combination treatment up-regulated the levels of suppressed stress factors,reduced the apoptosis of hippocampus induced by depression and regulated the apoptosis signaling pathway in hippocampus.Conclusion The combination of Kai-Xin-San and fluoxetine has been shown to be an effective treatment for depression-like behavior in animal models,resulting in a reduction in the required clinical dosage of fluoxetine.This effect may be attributed to the up-regulation of neurotransmitter expression,inhibition of stress axis activation,and central nervous inflammation.
