OBJECTIVE:To investigate the protective effect of the compatibilities of ginsenosides Rg1 and aconitine on myocar-dial cell of in vitro cultured heart failure model. METHODS:The myocardial cells of neonate rat were grouped into normal control group,model group,positive control group(Deslanoside injection,1×10-7 mol/L),ginsenosides Rg1 group(1×10-8 mol/L),acon-itine group (1 × 10-9 mol/L) or their compatibilities groups (1∶1,2∶1,1∶2,V/V). Except for normal control group,other groups were given 0.8%pentobarbital sodium to induce heart failure model of myocardial cells. After modeling,each group was given rele-vant medicine for 1 h,and then the activities of T-ATPase,Ca2+-Mg2+-ATPase,Na+-K+-ATPase in cells were all detected. The activi-ties of acyl carrier protein(ACP)and lactate dehydrogenase(LDH),and the contents of brain natriuretic party(BNP),TNF-α and total glycogen were measured in cell culture fluid. RESULTS:Compared with normal control group, T-ATPase and Ca2+-Mg2+-ATPase activities were decreased significantly in model group;meanwhile,Na+-K+-ATPase activity was increased signifi-cantly,and ACP,LDH activities and BNP content in cell culture fluid were increased significantly(P<0.05). Compared with mod-el group,the activities of T-ATPase in treatment groups were increased significantly,while the activity of LDH in cell culture fluid was decreased significantly;when the volume ratio of ginsenoside Rg1 to aconitine was 2∶1,protective effect was the strongest;the activities of Na+-K+-ATPase in aconitine group and compatibility groups were all decreased significantly,with statistical signifi-cance(P<0.05). The activities of ACP and BNP in cell culture fluid were all decreased in treatment groups,but the content of to-tal glycogen in cells and the TNF-α content of in cell culture fluid had no change (P>0.05). CONCLUSIONS:Compatibility of ginsenosides Rg1 and aconitine can improve ATPase activities and membranous permeability,regulate BNP secretion and protect myocardial cell of heart failure model,especially the compatibility of ginsenosides Rg1 to aconitine of 2∶1 ratio.

Objective: To investigate the current status of knowledge, attitudes and practices regarding drinking water among primary school students in rural areas of China, so as to provide scientific basis for implementing health interventions related to drinking water. Methods: From November to December 2023, a stratified cluster random sampling method was employed to select 6 354 fourth to sixth grade primary school students in Shanxi, Zhejiang, Jiangxi, Guangxi and Gansu for a questionnaire survey. A uniformly designed questionnaire (including basic information, drinking water-related knowledge, attitudes and practices indicators) was distributed and completed by the students themselves. The χ 2 test was used to analyze the differences in drinking water-related indicators among students of different gender and boarder, and Logistic regression was used to analyze the influencing factors of drinking water practices among students. Results: Among the indicators of drinking water knowledge, the awareness rate of appropriate daily water intake for respective student age groups was the lowest (27.90%). The awareness rate among nonresident students was significantly higher than that among boarding students (31.29%, 15.49%, χ 2=132.75, P <0.01). Regarding attitudes toward drinking water, 13.33% of the students believed that well water or tap water could be drunk directly, and 9.58% believed that going to the toilet at school was troublesome. Regarding practices, the self-reported water intake among students was 1 000 (600, 1 200) mL. The results of multifactorial Logistic regression showed that higher grades ( OR=1.60, 95%CI =1.34-1.92), nonresident students ( OR=1.32, 95%CI = 1.15 -1.52), northern region ( OR=1.43, 95%CI =1.27-1.61), knowledge of appropriate daily water intake ( OR=1.41, 95%CI =1.24-1.60), drinking temperature ( OR=1.43, 95%CI =1.28-1.60), scientific hydration methods ( OR=1.25, 95%CI =1.08- 1.44 ), and adopting scientific hydration methods regularly ( OR=1.75, 95%CI =1.50-2.04) were the independent influences on daily water intake attainment ( P <0.05). Conclusions Rural primary school students lack knowledge about healthy drinking water, have cognitive biases about safe drinking water and exhibit unhealthy drinking behavior. It is suggested that health education be carried out in combination with the characteristics of students to enhance their drinking water literacy.

To prepare recombinant human retinol binding protein 4 (RBP4) by using the baculovirus expression system and to detect its immunogenicity, the fusion DNA fragment of secretory signal peptide SS64 and human RBP4 gene was subcloned into a baculovirus transfer vector pFastBac-dual(pFBd), and the corresponding recombinant transfer plasmid was transformed into E. coli strain DH10bac, after transposition recombinant shuttle bacmid was screened out. The logarithmic phase Sf9 cells were transfected with the recombinant bacmid and then the recombinant baculovirus containing hRBP4 expression box were generated. After amplification of recombinant baculovirus, the recombinant baculovirus seeds were obtained. To express human RBP4, logarithmic phase Sf9 cells were infected with the virus seeds and SDS-PAGE and Western blotting were used to detect and identify the expression. Finally, to prepare a batch of RBP4 protein, logarithmic phase Sf9 cells in suspension culture were infected with recombinant baculovirus seeds and the supernatant was harvested after 120 hours post-infection for purification. Finally for preparation of polyclonal antibody and evaluation of immunogenicity, the recombinant hRBP4 from insect cells and from E. coli were immunized rabbits. Restriction enzyme digestion and sequencing confirmed that the recombinant baculovirus transfer plasmid was constructed correctly, and subsequently recombinant RBP4-bacmid was generated successfully. SDS-PAGE and Western blotting analysis suggested that human RBP4 protein was highly expressed in Sf9 cells with the molecular weight of approximately 23 kDa. The recombinant RBP4 protein could be secreted into the medium efficiently, and the expression level was calculated amount of 100 mg/L. Finally the rabbit antiserum was harvested after recombinant RBP4 immunization, therein the titer of antiserum against baculovirus recombinant RBP4 is 1:100 000 whereas the titer of antiserum against E. coli recombinant RBP4 is only 1:10 000. Overall, human RBP4 was high efficiently expressed successfully with good antigenicity in baculovirus system, and high affinity antiserum was obtained. A solid foundation was laid for the next step of the preparation of human serum RBP4 detection kit.

Tumor chemoprevention and treatment are two approaches aimed at improving the survival of patients with cancers. An ideal anti-tumor drug is that which not only kills tumor cells but also alleviates tumor-causing risk factors, such as precancerous lesions, and prevents tumor recurrence. Chinese herbal monomers are considered to be ideal treatment agents due to their multi-target effects. Astragaloside has been shown to possess tumor chemoprevention, direct anti-tumor, and chemotherapeutic drug sensitization effects. In this paper, we review the effects of astragaloside on tumor prevention and treatment and provide directions for further research.
