This paper mainly discussed how Chinese archaic ideologist realize emotionality. The contents include five aspects: emotionality is related to human nature and morality; Chinese pay more attention to cultivate himself according to morality, control his emotion and need, keep harmonious relationship with others, emotionality is in association with or- gans. The author thought that the meaning of Chinese emotionality is not only the emotional reaction of oneself, but in- volves comprehensive features of individual emotional response, dealing with matters and behaviors, and it is closely relat- ed to the cultivation of morality and human nature and relative to human nature and morality. Chinese opinion is different from western psychologists’thoughts.

BACKGROUND:Compared with smooth titanium, titania nanotubes cannot only induce mesenchymal stem cels osteogenic differentiation and promote bone integration, but also be used as drug nanocarriers. OBJECTIVE:To prepare dexamethasone-loaded titania nanotube system and to test its drug release characteristics. METHODS:Titania nanotubes were prepared by electrochemical anodic oxidation, and dexamethasone was dripped onto the prepared titania nanotubes. Subsequently layer by layer self-assembly technology was employed to fabricate gelatin/chitosan multilayered structure on the prepared samples. Scanning electron microscope and contact angle test were carried out during the process of building the gelatin/chitosan multilayered structure. The drug release was measured by a ultraviolet spectrophotometer. RESULTS AND CONCLUSION:Under the scanning electron microscopy, the fabricated titania nanotubes had integral structure with even tube size of about 70 nm and arranged regularly, and the nanotubes were completely covered and sealed by the gelatin/chitosan multilayered membrane. Contact angle test results showed that ever since the fifth layer, contact angles changed alternately and displayed a zigzag profile. Ultraviolet spectrophotometer test results showed that when cultured for 3 hours, the cumulative drug release was about 32.7% and demonstrated an initial burst folowed by sustained release. When cultured for 24 hours, the cumulative drug release about 52.3%. However, after cultured for 7 days, little drug release was detected. And there was about 8.0%-10.0% dexamethasone of initial loading preserved in nanotubes.

BACKGROUND:Whether the functional mandibular deviation wil cause osteal mandibular deviation and whether the mandibular growth pattern wil change are stil controversial. Vascular endothelial growth factor can increase the endothelial permeability, stimulate endothelial cel mitosis and promote angiogenesis and regulate the formation of bone. OBJECTIVE:To investigate the effect of functional mandibular deviation on the expression levels of vascular endothelial growth factor in condylar cartilage in growing rats. METHODS:Sixty four-week-old male Sprague-Dawley rats were randomly divided into control group (n=20) and experimental group (n=40). Each animal in experimental group received a nichrome appliance which was designed by our team. Lower mandible suffered from left functional deviation (2.1±0.3) mm to simulate functional mandibular asymmetry. RESULTS AND CONCLUSION:The number of vascular endothelial growth factor-positive cels in the sagittal posterior deviation region of rats with functional mandibular deviation was less than that in the non-deviation region at 7-28 days after model establishment. The number of vascular endothelial growth factor-positive cels was less in the sagittal central and coronal central deviation region than in the non-deviation region in rats with functional mandibular deviation at 14-28 days after model establishment, but was close to the control group. The number of vascular endothelial growth factor-positive cels was less in the coronal lateral deviation region than in the non-deviation region and control group in rats with functional mandibular deviation at 14-28 days after model establishment. These results indicated that after the mandible functional lateral deviation in adolescent rats, the expression of vascular endothelial growth factor was different in bilateral condylar cartilage, caused the alterations in osteoblast activity in cartilage, and possibly affected the normal growth and development of rat mandible, suggesting that functional mandibular deviation should be corrected as early as possible.

Objective To investigate the effects of miR-335-5p on the proliferation and apoptosis of osteoblasts which were exposed to high glucose condition, and explore its possible molecular mechanisms. Methods MC3T3-E1 osteoblasts were divided into four groups:control group(5. 5 mmol/L glucose), high glucose group(HG group, 22. 0 mmol/L glucose), agomir-335-5p group(transfected with agomir-335-5p and exposed to 22. 0 mmol/L glucose) , and agomir negative control group( agomir NC group, transfected with agomir negative control and exposed to 22. 0 mmol/L glucose), cultured for 7 days. Cell proliferaton, cell apoptosis, expressions of miR-335-5p and dickkopfhomolog1(DKK1)mRNA,proteinlevelsofDKK1andcysteinylaspartate-specificproteinase-3(caspase-3) were detected using MTT, flow cytometry, quantitative realtime PCR and western blot, respectively. Results Compared with control group, the expression of miR-335-5p mRNA and cell proliferation in HG group were significantly decreased(P<0. 05), while cell apoptosis and the protein levels of DKK1 and caspase-3 were increased significantly(P<0. 05), the expression of DKK1 mRNA did not change (P>0. 05). The miR-335-5p mRNA expression and cell proliferation in agomir-335-5p group were higher than those in HG group and agomir NC group(P<0. 05). However, Cell apoptosis and the protein levels of DKK1 and caspase-3 in agomir-335-5p group were lower than those in HG group(P<0. 05). Conclusion High glucose inhibits the proliferation and induce the apoptosis of MC3T3-E1 osteoblast through decreasing the expression of miR-335-5p and subsequently increasing the DKK1 expression.

Objective To observe the effect of alteplase intra-arterial thrombolysis combined with continuous monitoring of transcranial Doppler (TCD) in patients with acute cerebral infarction. Methods Fifty-four patients with acute cerebral infarction were divided into TCD group and control group by random digits table method. The patients of 2 groups were given alteplase intra-arterial thrombolysis, and the patients of TCD groups were combined with continuous monitoring of TCD. The degree of clinical neurologic impairment was evaluated by National Institutes of Health stroke scale (NIHSS) and Barthel index (BI). The condition of vascular recanalization was evaluated by the change of blood flow signal of TCD. CT was performed within 1 d after thrombolysis to detect intracranial hemorrhage and other adverse reaction. The degree of clinical neurologic impairment, blood vessel recanalization rate after thrombolysis and recanalization time and incidence of intracranial hemorrhage and other adverse reaction were compared between 2 groups. Results There were no statistical difference in NIHSS score before thrombolysis and 1 h after thrombolysis between 2 groups (P>0.05). The NIHSS scores 7 and 30 d after thrombolysis in TCD group were significantly lower than those in control group:(8.1 ± 4.9) scores vs. (12.1 ± 4.2) scores and (6.9 ± 3.1) scores vs. (10.9 ± 3.9) scores, there were statistical differences (P<0.05). The BI scores 7 and 30 d after thrombolysis in TCD group were significantly higher than those in control group: (78.5 ± 13.8) scores vs. (60.8 ± 12.4) scores and (82.6 ± 13.5) scores vs. (63.2 ± 12.9) scores, and there were statistical differences (P<0.05). The blood vessel recanalization rate 24 h after thrombolysis in TCD group was significantly higher than that in control group: 70.4% (19/27) vs. 44.4% (12/27), the recanalization time after thrombolysis was significantly shorter than that in control group: (36.4 ± 9.5) min vs. (58.5 ± 12.4) min, and there were statistical differences (P<0.05). No adverse reaction like intracranial hemorrhage and so on was found by CT detection within 1 d after thrombolysis in the 2 groups. Conclusions Alteplase intra-arterial thrombolysis combined with continuous monitoring of TCD in acute cerebral infarction has good curative effect, and no obvious adverse reaction.

Objective To evaluate the clinical effect of traditional Chinese medicine fumigation and herbal plaster for the patients with anal abscess. Methods A total of 140 patients with anal abscess were randomly divided into 2 groups, 70 in each group. The control group were treated with different operation methods according to the patient's health condition. the Potassium Permanganate solution (1:5 000) bath was used after surgery in the conventional anti anti-infection treatment; and the observation group were treated with herbal fumigation and plaster on the basis of the control group. The wound was treated in the both groups in the following 3 months after operation. The wound swelling disappearance, carrion shedding and healing time, pain relief, medical records of infection and recurrence were measured after the treatment and follow-up period. Results The total effective rate of the observation group was 100% (70/70), and the control group was 91.4% (64/70). The difference between the 2 groups was statistically significant (χ2=4.322,P=0.037). After 3, 7 days, the pain relief in the observation group was better than that in the control group (Z=9.742, 16.860,P=0.008, 0.001). After treatment, the observation group swelling (4.9 ± 0.7 dvs. 6.1 ± 0.7 d,t=10.142), carrion shedding time (3.8 ± 0.5 dvs. 4.2 ± 0.4 d,t=5.227), the wound healing time (22.1 ± 4.0 dvs. 26.9 ± 4.0 d,t=7.099) were lower than those in the control group (P<0.01). During follow-up, 4 cases (5.7%) with secondary infection and 2 cases (2.9%) with recurrence were in the observation group, but 20 cases (28.6%) and 6 cases (8.6%) in the control group.There were significantly difference of the secondary infection and recurrence between two groups (χ2= 6.092,8.934,P= 0.034, 0.001). 2 groups of secondary infection, the differences were statistically significant. Conclusions The combination of traditional Chinese medicine fumigation and herbal plaster could improve the wound healing time, reduce the secondary infection and recurrence rates of patients with anal abscess.
