Objective: To observe the treatment effect of hemifacial dysplasia by injecting transplantation of autologous dermis and fat granules in the second stage surgery for total auricle reconstruction. Methods: From March 2013 to March 2018, 57 patients with unilateral microtia and mild-to-moderate hemifacial dysplasia were divided into concurrent treatment group (32 cases, including 13 females and 19 males and aged 6-33 years old with an average age of 12.5 years) and traditional treatment group (25 cases, including 10 females and 15 males and aged 6-21 years old with an average age of 11.3 years) according to the different surgical methods. Modified Nagata method of auricular reconstruction was chosen, in the second stage surgery (cranial ear angle plasty), patients in concurrent treatment group received the treatment of hemifacial dysplasia with autologous dermal and fat injection transplantation at the same time; Patients in traditional treatment group only received cranial ear angle plasty. Statistical analysis of the two groups of patients was carried out for the average operation time, the average length of hospital stay, the incidence of common complications and postoperative satisfaction rate. SPSS 21.0 software was used for statistical analysis. Results: The mean operation time of the concurrent treatment group (282.0±3.4)min was longer than that of the traditional treatment group (243.0±3.1)min, and the difference was statistically significant (t=9.884, P<0.05). There were no statistically significant differences in the average length of stay between the the concurrent treatment group (9.4±0.3)d and the traditional treatment group(9.5±0.2)d, t=0.256, P>0.05. There were no statistically significant differences in the incidence of common surgical complications between the concurrent treatment group (12.5%, 4/32) and the traditional treatment group(12.0%, 3/25), χ2=0, P>0.05. Postoperative satisfaction rate of the concurrent treatment group(90.6%, 29/32) was significantly higher than that of the traditional treatment group(56.0%, 14/25), the difference was statistically significant (χ2=9.081, P<0.05). Conclusions: Auricular reconstruction with treatment of hemifacial dysplasia should not significantly increase the average length of stay and the incidence of common complications compared with auricular reconstruction alone. Although the operation time is slightly extended, the scheme of concurrent treatment can reduce the times of operations, save medical resources and increase the satisfaction rate of patients.

Mediating role of resilience between stress and social anxiety in military medical university students / 第二军医大学学报

Objective To investigate the relationship between stress and social anxiety of medical students in military universities, and to explore the related mechanisms. Methods Two hundred and eleven military medical university students were tested by interaction anxiousness scale (IAS), stress scale for college students (SSCS) and Connor-Davidson resilience scale (CD-RISC). The Pearson correlation analysis and structural equation model were used to analyze the relationship between the variables. Results A total of 198 valid questionnaires were collected, with the effective rate being 93.8%. There were significant correlations between social anxiety and various dimensions of stress and resilience (all P<0.01). Structural equation model showed that the resilience partially mediated the relationship between stress and social anxiety (Χ2/df=2.08, P<0.05; root mean square error of approximation=0.074, comparative fit index=0.98, normed fit index=0.97, incremental fit index=0.98). The total stress score of the male students was greater than that of the female students in military medical universities (24.67±15.01 vs 20.17±13.07, t=2.17, P<0.05). Conclusion Resilience has partial mediating effect on the relationship between stress and social anxiety. Therefore daily management of military medical university students should be emphasized on the cultivation of resilience.

UFLC-Q-TOF-MS fingerprints of rhizome of Curcuma phaeocaulis and its vinegar processed products and inhibitory effect on thrombosis / 中国中药杂志

Both raw and vinegar products of the rhizome of Curcuma phaeocaulis are common drugs for promoting blood circulation and removing blood stasis in traditional Chinese medicine,which could be reflected in the inhibition of tail thrombosis in mice. As the traditional processing theory instructs,vinegar tastes sour and bitter,but can activate blood circulation and remove stasis after being infiltrated into the rhizome of C. phaeocaulis as an excipient. In this study,under the help of the ultrafast liquid chromatography-quadrupole time-offlight mass spectrometry( UFLC-Q-TOF-MS),the spectrum-effect relationship between the inhibition of tail thrombosis in mice and the rhizome of C. phaeocaulis both before and after the vinegar processing,were established to explore the functional changes of blood circulation and stasis after vinegar process. Based on the peak area from the fingerprint of UFLC-Q-TOF-MS of the alcohol extracts from the raw and vinegar-processed rhizome of C. phaeocaulis and their efficacy for inhibiting tail thrombosis,the correlation between the chromatography of UFLC-Q-TOF-MS and the inhibition of tail thrombosis in mice were analyzed by orthogonal partial least squares discriminant analysis( OPLS-DA) method. The results,produced by Simca-P software,showed that effective components consisted of eight peaks 16,24( aromadendrene oxide),3,11,22( dehydro-α-curcumene),19[( R)-(-)-α-curcumene],23 and 10 from the fingerprint,making great contribution to distinguish C. phaeocaulis raw products and the corresponding vinegar processed products. Therefore,from the perspective of inhibiting the formation of tail thrombosis in mice,the marker components could be found through the spectrum-effect relationship to distinguish C.phaeocaulis raw and vinegar products. This study provided new basis to explain the difference between the raw and the processed products of traditional Chinese medicine in the functional change of promoting blood circulation and removing blood stasis.

Edaravone Enhances the Viability of Ischemia/reperfusion Flaps / 华中科技大学学报（医学）（英德文版）

The purpose of the experiment was to study the efficacy of edaravone in enhancing flap viability after ischemia/reperfusion (IR) and its mechanism.Forty-eight adult male SD rats were randomly divided into 3 groups:control group (n=16),IR group (n=16),and edaravone-treated IR group (n=16).An island flap at left lower abdomen (6.0 cm×3.0 cm in size),fed by the superficial epigastric artery and vein,was created in each rat of all the three groups.The arterial blood flow of flaps in IR group and edaravone-treated IR group was blocked for 10 h,and then the blood perfusion was restored.From 15 min before reperfusion,rats in the edaravone-treated IR group were intraperitoneally injected with edaravone (10 mg/kg),once every 12 h,for 3 days.Rats in the IR group and control group were intraperitoneally injected with saline,with the same method and frequency as the rats in the edaravone-treated IR group.In IR group and edaravone-treated IR group,samples of flaps were harvested after reperfusion of the flaps for 24 h.In the control group,samples of flaps were harvested 34 h after creation of the flaps.The content of malondialdehyde (MDA) and activity of superoxide dismutase (SOD) were determined,and changes in organizational structure and infiltration of inflammatory cells were observed by hematoxylin-eosin (HE) staining,apoptotic cells of vascular wall were marked by terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) assay,and the apoptotic rate of cells in vascular wall was calculated.The ultrastructural changes of vascular endothelial cells were observed by transmission electron microscopy (TEM).Seven days after the operation,we calculated the flap viability of each group,and marked vessels of flaps by immunohistochemical staining for calculating the average number of subcutaneous vessels.The results showed that the content of MDA,the number ofmulticore inflammatory cells and apoptotic rate of cells in vascular wall in the edaravone-treated IR group were significantly lower than those in the IR group.The activity of SOD,flap viability and average number of subcutaneous vessels in the edaravone-treated IR group were significantly higher than those in the IR group.All the differences were statistically significant.The ultrastructure injury of vascular endothelial cells in the edaravone-treated IR group was slighter than that in IR group.It was concluded that edaravone can significantly enhance IR flap viability and protect flap vessels,which is related to scavenging oxygen free radicals,reducing the consumption of SOD,reducing the extent of lipid peroxidation and inflammation,and protecting functional structure of vessels in the early stages of reperfusion.

Rib Cartilage Assessment Relative to the Healthy Ear in Young Children with Microtia Guiding Operative Timing / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>The optimal age at which to initiate for auricular reconstruction is controversial. Rib cartilage growth is closely related to age and determines the feasibility and outcomes of auricular reconstruction. We developed a method to guide the timing of auricular reconstruction in children with microtia ranging in age from 5 to 10 years.</p><p><b>METHODS</b>Rib cartilage and the healthy ear were assessed using low-dose multi-slice computed tomography. The lengths of the eighth rib cartilage and the helix of the healthy ear (from the helical crus to the joint of the helix and the earlobe) were measured. Surgery was performed when the two lengths were approximately equal.</p><p><b>RESULTS</b>The preoperative eighth rib measurements significantly correlated with the intraoperative measurements (P < 0.05). From 5 to 10 years of age, eighth rib growth was not linear. In 76 (62.8%) of 121 patients, the eighth rib length was approximately equal to the helix length in the healthy ear; satisfactory outcomes were achieved in these patients. In 18 (14.9%) patients, the eighth rib was slightly shorter than the helix, helix fabrication was accomplished by adjusting the length of the helical crus of stent, and satisfactory outcomes were also achieved. Acceptable outcomes were achieved in 17 (14.0%) patients in whom helix fabrication was accomplished by cartilage splicing. In 9 (7.4%) patients with insufficient rib cartilage length, the operation was delayed. In one (0.8%) patient with insufficient rib cartilage length, which left no cartilage for helix splicing, the result was unsatisfactory.</p><p><b>CONCLUSIONS</b>Eighth rib cartilage growth is variable. Rib cartilage assessment relative to the healthy ear can guide auricular reconstruction and personalize treatment in young patients with microtia.</p>

The first stage involved fabrication and grafting of a costal cartilage framework. A U-shaped skin incision was made on the posterior edge of the lobule and the remnant ear cartilage was removed completely. The area for the insertion of the cartilage framework was undermined. Skin flaps were sutured after insertion of the cartilage framework. The second-stage surgery was usually performed six months after the first-stage operation. The reconstructed auricle was elevated, and a costal cartilage block was fixed to the posterior part of the auricle. A temporoparietal fascia flap was then used to cover the costal cartilage block. Finally, the posterior aspect of the projected auricle was covered with a spit-thickness skin graft.</p><p><b>RESULTS</b>The incisions healed in one hundred and forty-one patients (150 ears) after the first stage operation. Partial necrosis of the postauricular flap was observed in five cases (5 ears) after the first stage operation, but no exposure or absorption of the cartilage took place. The skin grafts survived in one hundred and thirty-nine cases (147 ears) after the second-stage surgery. Partial necrosis of the skin graft was observed in seven cases (8 ears), but healed after one-week of dressing changes. Ninety-four cases (97 ears) were followed up, but fifty-two cases (58 ears) were lost to follow up. The follow-up at six months to two years showed satisfactory contour and projection of the constructed ears.</p><p><b>CONCLUSION</b>This two-stage surgery is simple and ideal for auricloplasty with few complications.</p>

Case-control study on therapeutic effects of Chinese herb of promoting blood circulation to dissipate blood stasis in the treatment of mudslide injuries / 中国骨伤

<p><b>OBJECTIVE</b>To observe the effects of Chinese herb of promoting blood circulation to dissipate blood stasis on the levels of tumor necrosis factor alpha (TNF-alpha) and interleukin 6 (IL-6) in serum of patients with mudslide injuries, and investigate the mechanisms of Chinese herb of promoting blood circulation to dissipate blood stasis in the treatment of mudslide injuries.</p><p><b>METHODS</b>Patients with mudslide injuries who were translated from Zhouqu and Chengxian to Lanzhou from 12th August 2010 were divided into two groups (group A and group B). Twenty-five patients in group A, containing 15 males and 10 females, with an average age of (39.0 +/- 3.9) years. According to AIS scoring system, 1 point in 2 cases, 2 points in 3, 3 points in 17 and 4 points in 3. No patients got 5 points. Based on ISS rating system, 16 cases got 16 points or less, 7 cases rated between 16 and 25, only 2 cases were equal to 25 points or more. Another 25 patients were in group B, including 11 males and 14 females, with a mean age of (40.1 +/- 3.6) years; AIS score showed 3 cases got 1 point, 4 got 2 points, 16 got 3 and 2 got 4 points, no patients got 5 points. Patients in group B were divided into three parts by ISS score:15 cases (16 points or less); 9 cases (range 16 to 25 points) and 1 case (25 points or more). All the patients accepted general physical checkup. Eight patients were treated by surgical treatment in group A (3 patients were treated with open reduction plate fixation, 4 patients were treated with debridement BHID, and 1 patient underwent foreign body removal) and 6 cases in group B (1 patient was treated with craniocerebral surgery,2 patients were treated with chest surgery, and 3 patients were treated with soft tissue debridement). All the patients of two groups were treated by support treatment, detumescence treatment and preventing infection, complications. A seven days course of treatment with detumescence analgesic mixture 50 ml p.o. bid, traumatologic cleansing liquid 20 ml ad us, ext 20 to 30 min qid to group A,continuous treatment of two courses. Using immunometric assay to determine serum levels of inflammatory cytokine TNF-alpha, IL-6 at the 2nd, 7th, 14th days after admission. Analysis of data were done with the help of SPSS 16.0 statistic software.</p><p><b>RESULTS</b>There were no statistical differences of TNF-alpha, IL-6 between two groups at the second day after admission, and there were statistical differences at the 7th and 14th days between two groups. There were significant differences of TNF-alpha and IL-6 levels between the 7th day and the 2nd day, the 14th day and 2nd day after admission.</p><p><b>CONCLUSION</b>The Chinese herb of promoting blood circulation to dissipate blood stasis can inhibit the release of inflammatory factor after traumatism.</p>
