Objective: To investigate the level of maternal and infant health literacy and its influencing factors among rural pregnant and lying-in women in Guian New Area, Guiyang City, so as to provide insights into maternal and infant health education. Methods: All pregnant and lying-in women included in health management in township hospitals of Guian New Area from October to December 2021 were selected using a stratified cluster random sampling method. Participants' basic features, maternal and infant health literacy and health education needs were collected using electronic questionnaires, and factors affecting maternal and infant health literacy were identified among pregnant and lying-in women using unconditioned multivariable logistic regression model. Results: A total of 918 valid questionnaires were recovered, and the participants included 325 pregnant women (35.40%), 823 married women (89.65%), 466 women with an educational level of junior high school and below (50.76%), 847 rural household registration (92.27%), 695 women with monthly family income of 3 200 Yuan and less (75.71%), and 267 women with maternal and infant health literacy (29.08%). Multivariable logistic regression analysis identified pluripara (OR=3.418, 95%CI: 1.689-6.919), educational level (diploma, OR=2.901, 95%CI: 1.230-6.842; bachelor and above, OR=6.282, 95%CI: 2.548-15.489), household monthly income per capita (3 201-5 000 Yuan, OR=2.373, 95%CI: 1.499-3.757; 5 001 Yuan and more, OR=7.752, 95%CI: 3.072-19.558), a disease history (OR=3.045, 95%CI: 1.175-5.406), use of maternal and child health manuals (OR=1.881, 95%CI: 1.345-2.632) and emphasizing health education (OR=1.735, 95%CI: 1.122-2.463) as factors promoting for the level of maternal and infant health literacy. In addition, pregnant and lying-in women's major maternal and infant health education needs included infant growth and development knowledge (745 women, 81.15%), management of common infant diseases (719 women, 78.32%), daily infant nursing (651 women, 70.92%) and infant nutrition and feeding (646 women, 70.37%). Conclusions The level of maternal and infant health literacy is low among rural pregnant and lying-in women in Guian New Area, and there is a high demand for health education. High attention should be paid to rural pregnant and lying-in women with a low educational level, low incomes, and primipara.

AIM　To improve the treatment efficacy of anti-tumor drug mitoxantrone, the conjugation of mitoxantrone-loaded nanospheres and anti-C-erbB-2 monoclonal antibodies were prepared. METHODS Mitoxantrone-loaded nanospheres were prepared with emulsion-heating solidification technique. A heterobifunctional reagent, N-succinimidyl 3-(2-pyridyldithio) propionate (SPDP), was used as the crosslinker of mitoxantrone-loaded nanospheres and anti-C-erbB-2 monoclonal antibodies; pharmaceutical properties of immunonanocapsuls were studied; the conjugates of nanospheres and monoclonal antibodies was confirmed with immunological methods such as slide agglutination test, fluorescent immunossay and rosset formation test, fluorescent staining and scanning electron microscope. RESULTS　Mitoxantrone-loaded nanospheres were spherical, with smooth surface and median diameter of 0.665 micron. When stored at 3-5, 20-25 and 37℃, RH 75% for three months, the appearance, morphology, size distribution, drug loading and in vitro release characteristics showed no significant change and the stability was satisfactory. The size analysis demonstrated that there was no obvious increase in the particle size of nanoparticles after conjugation. Immunological tests indicate highly selective binding of antibody-targeted nanospheres to C-erbB-2-overexpressing cells SK-BR-3. CONCLUSION　The conjugation of mitoxantrone-loaded nanospheres and anti-C-erbB-2 monoclonal antibodies can keep the activity of anti-C-erbB-2 and increase the therapeutic efficacy of anti-mammary cancer drugs.

ObjectiveTo observe clinical results and histopathological changes of scleral defect repaired with acellular xenogenic dermal matrix (Xeno-ADM) in rabbits.MethodsModel of rabbit sclera defect was established, and repaired with Xeno-ADM. The rabbits were clinically examined for inflammation and eyeball healing. The animals were sacrificed at 2nd and 4th week after operation, and implants were obtained and examined histopathologyically and ultrastructully with light microscopies respectively to evaluating changes of inflammation and vascularization.ResultsThere were no obvious inflammation and eyeball deformation observed. 2 weeks after implantation, the partial inflammatory cell invasion was seen with the light microscopy, and there was an obvious borderline between the Xeno-ADM and the sclera. 4 weeks after implantation, the inflammatory cells were reduced noticeably, the Xeno-ADM and the sclera completely merged with each other.ConclusionThe acellular xenogenic dermal matrix may be an ideal materix with fast neovascularization and low immunity for replace of sclera implants.

OBJECTIVETo evaluate the role of the combined periodontic-orthodontic treatment in the esthetic reconstruc- tion of the anterior teeth area following periodontitis.

METHODSThirteen adult patients with anterior teeth displacements were treated. The probing pocket depth (PD; 102 teeth, 612 sites), bleeding on probing (102 teeth, 204 sites), papilla index (PI; 128 papillae), and papillary height (PH; 128 papillae) of each patient were assessed at baseline, 3 months after the initial therapy, and the end of the orthodontic treatment. Non-parametric and paired-sample t tests were carried out for the statistical analysis of the data.

RESULTSThree months after initial therapy, the sites with PD ≤ 3 mm accounted for 79.58% (487/612) of the observed teeth, and 88.73% (181/204) of the buccal and lingual sites of the teeth showed negative bleeding on probing. These findings were better than those at baseline [26.31% (161/612) and 22.06% (45/204), respectively] (P < 0.05), but no sig- nificant difference was observed compared with pro-orthodontic treatment (P > 0.05). Prior to orthodontic treatment, the levels of the PI of 8 and 21 papillae were III and II, respectively, among the 128 observed papillae. After the orthodontic treatment, 51 papillae were at level III and 68 papillae were at level II. The PH of the 102 papillae was 2.84 mm ± 0.62 mm after ortho- dontic treatment. This result indicated significant difference compared with that of pre-orthodontic treatment (1.69 mm ± 0.57 mm) (P < 0.05).

CONCLUSIONAfter initial therapy, moderate orthodontic teeth movements may reconstruct the interproximal soft tissue, with esthetic improvement of the papillary level and resolution of the periodontal defects.

Objective To study the gene expression profiles of megakaryocytes(MKs) from human cord blood CD34+ cells in vitro expanded and to understand megakaryopoiesis at the molecular level. Methods CD34+ cells were isolated using density gradient centrifugation and magnetic activated cell sorting. The cells were cultured and stimulated with recombinant human TPO ( 100 ng/ml). After 12 days, the MKs fraction was separated using an anti-CD41 monoclonal antibody by immunomagnetic sorting. The gene expression profiles of MKs, non-MKs as well as meg-01 cells were studied by gene chip assay. THBSI, HOX A9,β-actin, lL-8,Annexin A6, FGF-8 were selected to validate the gene chip results by RT-PCR. Results A total of 116 genes between MKs and non-MKs cells were significantly different, 52 genes were up-regulated and 64 genes were down-regulated. In addition, 158 genes between MKs and meg-01 cells were significantly different, 71 genes were up-regulated and 87 genes were down-regulated. THBSI showed higher expression in MKs than in non-MKs. HOXA9 showed lower expression in MKs than in non-MKs. The expression of β-actin did not show any significant difference in MKs and non-MKs. IL-8 showed higher expression in MKs than in meg-01 cells, while ANXA6 showed lower expression in MKs than in meg-01 cells. The expression of FGF-8 did not show any significant difference between MKs and meg-01 cells. Conclusions MKs, non-MKs and meg-01 cells show different gene expression profiles. The regulatory genes include stress response genes,immune related genes, DNA synthesis and repair genes, metabolism genes, pro-onco genes and tumor suppressor genes.
