Journal of Guangzhou University of Traditional Chinese Medicine 2016;33(5):720-726
Objective To find out evidences for the identification of Ajuga decumbens Thunb.(Jinchuangxiaocao) and Pogostemon cablin (Blanco.) Benth.(Guanghuoxiang) . Methods Fresh stems and leaves of the two species were collected and used as the samples. We used stereoscopy to observe and compare the macroscopic appearance of the original plants, and used light microscope to observe the stem cross-section, petiole cross-section, leaf epiderm and powder of the two species for microscopic identification. Results The results of macroscopic character identification showed that the petiole of Jinchuangxiaocao had narrow wing, while that of Guanghuoxiang had no narrow wing; the angles between leaf main vein and lateral vein of Jinchuangxiaocao were less than 45°, while the angles of Guanghuoxiang were more than 45°. In respect of microscopic identification, Jinchuangxiaocao had the glandular scales with multicellular head, and Guanghuoxiang had the glandular scales with one-celled head; the intercellular space and crystals were found in the cortex of Guanghuoxiang stems and mesophyll, while Jinchuangxiaocao has no such structures. Jinchuangxiaocao had diacytic and anomocytic stomata, and Guanghuoxiang only had diacytic stomata. Conclusion The appearance and microscopic differences can be used for the identification of Jinchuangxiaocao from Guanghuoxiang.

Objective To investigate the protective effects of pulmonary surfactant (PS) in lung transplantation.Methods Forty-eight rabbits were divided into control group (group C),PS1 group,and PS2 group. Rabbit lungs were harvested and preserved at 4 ℃ for 6 h before transplantation. The PS1 group received 100 mg /kg of intratracheal PS before reperfusion,while the PS2 group received the same dosage PS before preservation. Using the hetero-heart-lung transplantation model,pulmonary graft function and airway compliance was assessed every 30 min for 3 h when the model was transformed into self-working state. After finishing the observation,the tissue specimens were taken for analysis of wet/dry ratio (W/D),the contents of malondialdehyde (MDA) and myeloperioxidase (MPO). All values were compared to the control group.Results The two groups treated with PS showed better airway compliance and higher PaO 2 and lower PaCO 2 than group C ( P

Objective To investigate the impact of daily life ability, self-efficacy and social support on post-stroke depression. Methods This was a cross-sectional questionnaire survey. A convenience sample of stroke patients from neurology department was created. Data were collected from patients about their level of daily life ability, self-efficacy, social support and depression measured. Inferential statistics multiple regression analysis was used to estimate the relationships between the predictors and post-stroke depression. Results A total of 144 (96.00%) of 150 stroke patients completed the questionnaires. The level of depression was 14.19 ± 9.25 with 25.00% (36/144) of incidence of post-stroke depression. Self-efficacy scored 40.45 ± 11.41, social support scored 28.34 ± 8.02, which negatively predicted depression (r=-0.834 and-0.736, P<0.01 respectively). Self-efficacy had the most significant impact on depression (t=-6.433, P < 0.01), however, the impact from daily life ability scored 76.74 ± 22.12, which had not statistically significant impact on depression (t=-1.773, P=0.083). Conclusions During treatment and nursing management of post-stroke depression, attention should be paid to the psychiatric variable such as self-efficacy and social support.

Objective To demonstrate the histology in acellular dermal matrix(ADM)after being transplanted in vivo over time. Methods Forty male SD rats were recruited for the experiment. Subcutaneous implantation of an 1 cm × 1 cm ADM was given in the left sides on the back of the rat for the experimental group, while only dissection and suturing were performed in right side of the back for the control group. All the animals will be sacrificed at appointed time after operation, Five ADM samples were harvested in each time point. The content and proportion of collagen type were examined with HE staining, Picrosirius staining, Masson′s trichrome staining, and Immunohistochemical staining (targets: pan macrophage, M1 macrophage and M2 macrophage). Results All rats survived after operative without any complications. Significant differences of thickness were not observed at the end of 5 months; HE scores suggested that ADM increased in cell infiltration scores in 2 weeks before the plateau , vascularity also showed a similar trend; Collagen trichrome staining showed a substantial increase in density of collagen bundles with time. The comparison of the proportion of collagen among days showed significant differences (P < 0.05). Immunohistochemical staining of M1 and M2 showed that macrophages had distinct polarization profiles in materials. Furthermore, the comparison of M1 vs M2 response associated with different materials showed significant differences in all time points (P < 0.05). Conclusions The chemically cross-linked ADM could keep long time in the body; ADM significantly stimulated proinflammatory of M2 differentiation from M1 in constructive remodeling.
