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.

Collagen triple helix repeat containing 1 (CTHRC1) can repair the injured vessel by limiting the deposition of collagen and promoting cell migration.CTHRC1 is mainly regulated by Wnt-PCP signaling pathway,transforming growth factor (TGF)-bone morphogenetic protein (BMP) signaling pathway and extracellular signal-regulated kinase (ERK)-matrix metalloproteinase 9 (MMP9) signaling pathway.Recent studies have identified that CTHRC1 is aberrantly expressed in gastrointestinal cancers and associated with the occurring and development of cancers.

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.

OBJECTIVEThis study aims to construct a three-dimensional finite element model of a maxillary anterior teeth retraction force system in light wire technique and to investigate the difference of hydrostatic pressure and initial displacement of upper anterior teeth under different torque values of tip back bend.

METHODSA geometric three-dimensional model of the maxillary bone, including all the upper teeth, was achieved via CT scan. To construct the force model system, lingual brackets and wire were constructed by using the Solidworks. Brackets software, and wire were assembled to the teeth. ANASYS was used to calculate the hydrostatic pressure and the initial displacement of maxillary anterior teeth under different tip-back bend moments of 15, 30, 45, 60, and 75 Nmm when the class II elastic force was 0.556 N.

RESULTSHydrostatic pressure was concentrated in the root apices and cervical margin of upper anterior teeth. Distal tipping and relative intrusive displacement were observed. The hydrostatic pressure and initial displacement of upper canine were greater than in the central and lateral incisors. This hydrostatic pressure and initial intrusive displacement increased with an increase in tip-back bend moment.

CONCLUSIONLingual retraction force system of maxillary anterior teeth in light wire technique can be applied safely and controllably. The type and quantity of teeth movement can be controlled by the alteration of tip-back bend moment.

Objective To study the imaging features of sacroiliac joints(SIJ) in patients who were misdiagnosed as spondyloarthritis(SpA).Methods A total of 34 patients with chief complaint of back pain and misdiagnosed as SpA from January 2007 to April 2013 in Department of Rheumatology Chinese PLA General Hospital were enrolled.The imaging,clinical manifestations,laboratory examinations data were analyzed.Result The main reason for misdiagnosis as SpA was because of sacroiliitis presenting on imaging.The final diagnoses included 24 patients as SIJ infection,4 patients as neoplastic diseases,2 patients as metabolic bone diseases,2 patients as sacroiliac joint degeneration,1 patient as gout of sacroiliac joint,1 patient as diffuse idiopathic bone hypertrophy.For patients with infection,there were 10 patients receiving X-ray and 22 patients receiving CT of SIJ.However,5 and 7 patients had negative results respectively.These patients with infection had abnormalities in MRI including all with bone marrow edema,21 patients with erosion of bone and joint,22 patients with muscle involved.As to the patients with malignancies,SIJ CT scan appeared normal.Bone marrow edema and erosion in MRI were found in all neoplasm patients expect one as ependymoma.Adjacent muscles were involved in the patient with Ewing's sarcoma.Either X-ray or CT in other patients demonstrated obvious abnormalities,but only mild erosion of bone was found in MRI.Conclusion Bone marrow edema of SIJ in MRI represented not only in patients with SpA.Rheumatologists should analyze the clinical manifestations and laboratory examinations comprehensively in order to avoid the misdiagnoses.

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.

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.

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.
