OBJECTIVETo explor the curative effect of double pedicle sliding skin flap for correction of cryptotia.

METHODSFrom January 2011 to October 2014, 7 cases with cryptotia (12 ears) were treated. We designed a double pedicle sliding skin flap above the helix. The flap was slided downward to form a new auriculocephalic sulcus. The other wound was covered by skin graft.

RESULTSAll wounds healed very well with no complication. The follow-up period ranged from 3 months to 1 year, with an average of (5.67 ± 3.38) months. The ear had stable appearance with no recurrence. The result was satisfactory.

CONCLUSIONSThe method is simple with reliable flap survival rates. The new auriculocephalic sulcus is stable and resistant. It's a good choice for correction of cryptotia.

Background Human Tenon fibroblasts (HTFs) are the main cell component in scar tissue after antiglaucomatous filtrating surgery.To study the in vitro growth and proliferation features will offer an approach to the preventing and treating of scarring following antiglaucomatous filtrating surgery.Objective The goal of present study was to investigate the growth characteristics of HTFs in vitro from patients with bleb scarring after antiglaucomatous filtrating surgery.Methods This study process was approved by Ethic Committee of Beijing Chaoyang Hospital,and informed consent was obtained from each subject prior to the initaion of the study.The specimens of scaring tissue were obtained during the secondary trabeculectomy from 8 eyes with bleb scaring after initial antiglaucomatous filtrating surgery with the tissue size of 4 mm×5 mm,and the normal Tenon capsule specimens were acquired during the strabismus surgery from 8 eyes in the same way.HTFs were primarily cultured and passaged by tissue explants adherent method and identified using immunoinfluorescence technique with vemintin antibody.Nest PCR was used to exclude the mycoplasma infection during the culturing process.The morphology,growth curve and population doubling time (PDT) of the fifth generation of cells were examined and calculated by luminescence method cell vitality method 0,4,7,11,14 days and compared between the patients and normal groups.The stability of the cell growth was assessed by comparing the morphology,growth curve and PDT between the fifth generation and fifteenth generation of HTFs.Results Primarily cultured cells reached confluence 1-2 weeks with the similar shape to HTFs.The growth properties of the cells were same between the scarring group and normal group and showed positive response for vemintin antibody.No react band for mycoplasma was detected.The PDT was (20.54±3.51) hours and (18.86±2.91) hours in the scarring group and normal group,respectively,showing insignificant difference between them (t=0.634,P=0.561).No significant differences were found in the number of cells in 4,7,11 and 14 days after passage (t =2.663,P =0.081; t =0.194,P =0.863 ; t =3.338,P =0.053 ; t =0.627,P =0.565),with a consistent growth curve with the lapse of time between the two groups.The HTFs from scarred Tenon capsule fibrosis were cultured and passaged until the fifteenth generation.The PDT was gained to be (20.54 ±3.51) hours in the fifth generation of cells and (22.84±4.15) hours in the fifteenth generation of cells,without significant difference between them (t =0.733,P =0.505).The number of cellsin 4,7,11 and 14 days was not significantly different between the fifteenth generation and the fifth generation of cells (t=1.528,P=0.235;t=0.269,P=0.786;t=1.954,P=0.139;t =0.730,P =0.506).In addition,a good and stable growth curve also was exhibited in the fifteenth generation of cells compared with the fifth generation of cells.Conclusions Bleb scar-derived HTFs present good and stable growth in vitro.This result demonstrates HTFs were target cells in antifibrosis study after antiglaucoma filtrating surgery.

Objective To investigate the effect of mindfulness on anxiety and depression of gynecological oncology patients.Methods Using objective methods,80 patients with gynecological oncology were divided to the usual care group and mindfulness training group according to random number table,40 cases in each group.The self -rated anxiety scale and self -rated depression scale were used to compare the effects at three times.Results There were 3 patients lost and 77 patients were analyzed finally.The ANOVA showed that there were significant differences on anxiety and depression scores of SAS (F =4.614,P =0.035) and SDS (F =4.070,P =0.044) between the two groups,and the scores of SAS (F =15.115,P <0.001) and SDS (F =7.034,P =0.002) had interaction effects. Conclusion Mindfulness can adjust the psychology state of gynecological oncology patients and decreased the level of anxiety and depression.

ObjectiveTo evaluate the ability of high resolution magnetic resonance (MR) imaging at 3.0 tesla to depict the characterization of human carotid arterial vessel wall and detect atherosclerotic lesions ex vivo in comparison to histopathologic results. MethodsEighteen carotid arteries obtained from 9 elderly donors underwent fat-suppressed T1 - and T2-weighted MR imaging at 3.0 tesla MR system with a mouse coil. Corresponding histological sections were obtained for the comparison. Correlation between MR images and histopathologic slices was obtained by Pearson or Spearman correlation coefficient.Cohen K was computed to quantify the agreement between MRI and histopathologic findings.Results Lumen area,intima and media area measured on fat-suppressed T2-weighted images showed stronger correlation with the corresponding histopathologic slices [ MRI vs.histopathology:( 27. 53 ± 6. 77 ) mm2 vs.( 25.83 ±6. 69 ) mm2, r2 ＝ 0. 91,P2 ＝ 0. 024, ( 12.31 ± 3. 31 ) mm2 vs.( 12. 28 ± 3.71 ) mm2, r2 ＝ 0. 70, P2 ＝ 0. 020,Median 12. 29 mm2(Min 1.12 mm2, Max 33.18 mm2) vs.Median 11.62 mm2(Min 0.89 mm2, Max 32. 84 mm2 ), r2 ＝ 0. 74, P2 ＝ 0. 016, respectively]. The Cohen K score between the MR imaging and American Heart Association classifications was 0. 74, which corresponds to a good agreement. Conclusions 3.0 T high-resolution multi-sequence MRI can clearly show the structure of ex vivo carotid artery wall and allow quantitative assessment.Fat-suppressed T2Wimaging has a greater advantagein presenting atherosclerotic lesions.

BACKGROUND:Nasolabial fold flap has been widely used in clinical surgery. The facial artery anatomy has been widely used in clinical research. Angular artery dissection is becoming more and more important to nasolabial groove area surgery, but at present, there is a lack of anatomical analysis of internal angular artery.
OBJECTIVE:To study the anatomy of the angular artery, and to provide anatomical data for protecting the nasolabial flap during surgery.
METHODS:Twenty sides of adult cadaver specimens on head and face were dissected. A reference coordinate system was made based on the line between the connection of two medial angles of eyes (axis X) and the facial midline line (axis Y). The location of the angular artery was measured taking A-F as reference points.
RESULTS AND CONCLUSION:(1) The slant angles of the angular artery on BC section, CD section, DE section and EF section were (11.1±4.3)°, (34.1±8.8)°, (21.5±10.5)°, and (17.0±4.7)°, respectively. (2) The angular artery sourced from facial artery was more than it sourced from ophthalmic artery. The diameter of right blood vessel was larger than that of left side. (3) The angular artery sourced from ophthalmic artery comes from the location which extended 8.1 mm to both sides from the point which was 10 mm up from the intersection of facial medial angle of eyes connection and midline. The blood vessel diameter of the starting point was (0.7±0.2) mm. The whole range was 20.1 mm. (4) The angular artery sourced from facial artery comes from the location which extended 25.8 mm to both sides from the point which was 40 mm down to the intersection of facial medial angle of eyes connection and midline. The blood vessel diameter of the starting point was (0.9±0.3) mm. Point to the wing of nose the lateral distance was (5.0±1.2) mm. The whole range was 68.7 mm. The surface projecting of angular artery coming from research results provided anatomic basis for surgery of nasolabial flap.

Objective To analyze and explore the value of 3 T high resolution magnetic resonance vessel wall imaging for identifying the activity of Takayasu arteritis. Methods Twenty-six consecutive patients with Takayasu arteritis underwent 3.0 T high resolution MR vessel wall imaging on supraortic vessels (according to the classification of Lupi-Herrea , type Ⅰ and Ⅲ were included). Sixteen patients were in active phase and 10 in inactive phase based on the Kerr criteria. The MR vessel wall imaging appearances of Takayasu arteritis were compared between the active phase and inactive phase cases. Results Wall thickening was demonstrated in all involved arteries. There were statistically significant differences between active phase and inactive phase cases in MR appearances including multi-ring thickening of vessel wall (75/80 and 18/50), arterial inner wail enhancement (50/80 and 19/50), obscurity of perivascular fat (55/80 and 18/50,X<'2>=50.39,7.41,13.40,P<0.01). There was also a statistically significant difference in the thickness of carotid artery wall between the two groups [ (3.8±0.2) mm vs (2.5±0.8) mm]. Conclusion 3 T high resolution MR vessel wall imaging is valuable for identifying the activity of Takayasu arteritis.

Objective To investigate the relationship between the levels of programmed death ligand 1 (PD-L1) on circulating B cells and disease severity as well as renal injury of patients with systemic lupus erythematosus (SLE) .Methods 50patients with SLE were enrolled from May 2015to May 2017, and 20healthy individuals were enrolled as the control group.All patients were scored for their disease severity and renal injury.The expression of PD-L1on circulating B cells were evaluated by flow cytometery.Results In the group of patients with active SLE, the percentage of CD19+in B cells was (11.35±3.65) ％and the percentage of in CD19+B cells was (2.47±0.89) ％, both of which were significantly higher than that in the group of patients with non-active SLE and control group (P<0.05) .In addition, patients with SLE were divided into lower group and higher group according to the median percentage of CD19+and CD19+/PD-L1Bcells.The incidence of kidney lesion was robustly increased in the high group, and CD19+/PD-L1Bcells, LNⅣwere independent risk factors of renal insufficiency in lupus nephritis.Conclusion The level of peripheral CD19+/PD-L1in SLE patients increased significantly and was closely related to the activity degree and renal injury of the disease, which was an independent risk factor for renal insufficiency in patients.

Objective:To explore the relationship among the supratrochlear and supraorbital neurovascular bundles and the corrugator muscle, in order to provide anatomical basis for eyebrow operations.Methods:From July to October 2019, the upper eyelids and forehead of 10 adult skull specimens (20 sides) were dissected layer by layer in the anatomy laboratory of Weifang Medical College. The line of bilateral inner canthus was taken as the X-axis and the facial midline as the Y-axis to establish the coordinate system. The coordinate parameters of supratrochlear nerve, supratrochlear artery, medial branch of supraorbital nerve, lateral branch of supraorbital nerve and supraorbital artery were measured to obtain the range of its trajectory, and their level and their adjacent relationship with the corrugator muscle were observed.Results:The corrugator muscle started from the upper part of the nasal process of the frontal bone near the medial margin of the orbit and was (4.32±0.98) mm from the midline. The base of the corrugator muscle start was (9.91±1.41) mm wide. The corrugator muscle run obliquely upward, through orbicularis oculi muscle and frontal muscle, and stopped at subcutaneous of the outer 1/3 of eyebrow. The trapezoid area was composed of the line of 15 mm above the inner canthus line, (16.58±1.70) mm and (16.17±1.42) mm from the facial midline as the lower base and the line of 30 mm above the inner canthus line, (13.74±1.54) mm and (14.21±2.42) mm from the facial midline, which was the dangerous area for the supratrochlear neurovascular bundles walking in corrugator muscle. The trapezoid area was composed of the line of 22.5 mm above the inner canthus line, (26.03±1.55) mm and (28.11±2.46) mm from the facial midline as the lower base and the line of 40 mm above the inner canthus line, (31.23±3.19) mm and (38.20±2.94) mm from the facial midline, which was the dangerous area for the supraorbital neurovascular bundles.Conclusions:Familiar with the relationship among the supratrochlear and supraorbital neurovascular bundle and the corrugator muscle can avoid dangerous areas and reduce superficial and deep neurovascular injury during operation.

The database with standard 3D tooth crowns has laid the groundwork for dental CAD/CAM system. In this paper, we design the standard tooth crowns in 3DS MAX 9.0 and create a database with these models successfully. Firstly, some key lines are collected from standard tooth pictures. Then we use 3DS MAX 9.0 to design the digital tooth model based on these lines. During the design process, it is important to refer to the standard plaster tooth model. After some tests, the standard tooth models designed with this method are accurate and adaptable; furthermore, it is very easy to perform some operations on the models such as deforming and translating. This method provides a new idea to build the database with standard 3D tooth crowns and a basis for dental CAD/CAM system.
