Objective To investigate the epidemiological features of 937 patients wounded in China Wenchuan earthquake. Methods An analysis was done on 937 patients treated in the city of Deyang in aspects fo their gender,age,injury causes,wound sites,complications and misdiagnosis.Results There were more wounded females than males,with ratio of male to female of 1:1.12.The main injury causes were crush injury and falling injury.The most frequent injury sites include head,chest,ankle and foot,tibia and fibula,spine and hip.The rate of misdiagnosis was as high as 15.5%,mainly brain injuries and chest iniuries. Conclusion The main causes are crush iniury and falling in-jury.Lower limb fractures account for the most.While close brain and thoracic injuries are likely to be misdiagnosed.

Objective:To summarize the age, gender difference, cause, location, time, treatment and prognosis of femoral intertrochanteric fracture complicated with pseudoaneurysm, and analyze the influence of different treatment methods on the occurrence of femoral intertrochanteric fracture complicated with pseudoaneurysm.Methods:Using the method of systematic literature review, a total of 76 literatures were retrieved from multiple databases at home and abroad, and 45 literatures were screened out through the second screening of title, abstract and full text. The patients with intertrochanteric fracture complicated with pseudoaneurysm were selected as the research objects, and the duplicate cases were deleted; the age, gender, onset age, etiology, location, treatment and prognosis of the disease were retrospectively analyzed.Results:A total of 54 cases of femoral intertrochanteric fracture related pseudoaneurysms were selected from 45 literatures, including 25 males and 27 females, and 2 cases had no gender; aged from 43 to 94 years old, and 4 cases were younger than 60 years old, 6 between 61 and 70, 17 between 71 and 80, and 25 between 81 and 90. Forty-five cases occurred in deep femoral artery, 3 cases in superficial femoral artery, 1 case in superior gluteal artery, 1 case of medial circumflex artery, 1 case of lateral circumflex femoral artery, 1 case of femoral artery, and 2 cases of unknown location. The occurrence time of pseudoaneurysm: 17 cases within 1 week after fracture, 8 cases from 1 week to 3 weeks, 19 cases from 3 weeks to 3 months, 2 cases more than 3 months, and 8 cases unknown. The causes of pseudoaneurysm: among the 54 patients, 41 cases had definite causes, including 21 cases of vascular injury caused by fracture block; 20 cases of iatrogenic injury, of which the incidence of direct injury of blood vessels by screw or drill was the highest, accounting for 55% (11/20). Twenty-two cases were treated with vascular embolization, 10 cases with surgical sutures, 8 cases with surgical ligation, 4 cases with resection of pseudoaneurysm, 5 cases with covered stent, and 4 cases with thrombin injection. There were 42 cases who had follow-up data, and no recurrence and other complications were found during the follow-up period.Conclusion:The peak age of femoral intertrochanteric fracture complicated with pseudoaneurysm was 71-90 years old. The incidence of femoral intertrochanteric fracture complicated with pseudoaneurysm was more often within 1 week after fracture and 3 weeks to 3 months after fracture, due to fracture fragments and iatrogenic vascular injury caused by the location of the profundus femoris artery. Treatment options include vascular embolization, surgical ligation, suture or resection of pseudoaneurysm, covered stent and thrombin injection, and the prognosis is generally good.

Objective To analyze the value of cerebral coronary view of nose tip deflection in screening fetal facial deformity in the first and second trimester. Methods All cases were divided into the 11～12+6 weeks, the 13 ～ 14+6 weeks and the 15 ～ 16+6 weeks undergone ultrasonographic examination on coronal view of nose tip deflection.

The median sagittal section ,eyes level coronal section ,retronasal triangle section ,or other sections were satisfactory in 4855 cases (97.10％). There was no Statistical difference in the display of fetal facial structures among the three groups. 69 fetus were found with facial malformations,including 31 fetus with facial malformations only,and 38 fetus combined with other abnormal struc-tures. The sensitivity,specificity,positive predictive value and negative predictive value were 93.24％,100％, 100％ and 99.90％ respectively. Conclusion The cerebral coronary view of nose tip deflection method has high detection rate and sensitivity,and is a reliable method for detecting fetal facial abnormalities in the first and second trimester.

OBJECTIVE: To study the expression of PD4, CD44 and PCNA proteins in laryngeal carcinoma and their relationships with the pathogenesis, development and prognosis of laryngeal carcinoma. METHOD: Immunohistochemistry was used to study 140 cases of laryngeal carcinoma tissues, 25 cases of precarcinoma tissues, 36 cases of vocal cord polyps and 13 cases of normal tissues adjacent to laryngeal carcinoma. RESULT: 1. The positive rates of PD4, CD44 and PCNA were 45.71% (64/140), 64.29% (90/140) and 77.86% (109/140) in laryngeal carcinoma, which were much higher than in non-carcinoma tissues (P < 0.01). 2. The third and fourth stages laryngeal carcinoma express stronger PD4 and CD44 than those of the first and second stages. Laryngeal carcinoma with cervical metastasis had higher expression than those without cervical metastasis. To 3 and 5 years' survival, PD4, CD44 and PCNA positive cases had lower chance than those negative cases(P < 0.01 or 0.05). 3. The over all positive rate of PD4, CD44 and PCNA was 27.86% (39/140) in laryngeal carcinoma tissues and 5.41% (4/74) in non-carcinoma tissues. CONCLUSION The high expression of PD4, CD44 and PCNA proteins maybe closely related to the pathogenesis, development and prognosis of laryngeal carcinoma.

OBJECTIVE: Exploring a method of rhinoplasty and septoplasty to get better nasal function and aesthetic effect. METHOD: 1) Using endoscopic rhinoplasty and septoplasty, separating the joint of quadrangular cartilage and the bones around it, resecting vertical and horizontal strip of the deviated septal cartilage and fracturing the deviated septal bones and reconstructing them with three layers (mucosa-cartilage or bone-mucosa), positing the reconstructed septum in the middle between two lateral walls of nasal cavity, proper space between septum and turbinates was maintained. 2) The caudal part of quadrangular cartilage was resected and placed in the columella pocket between the two medial parts of the alar cartilage and the supporting function of the septal cartilage was maintained. RESULT: Compared with traditional nasal septal reconstruction surgery, our method got better functional and aesthetic outcome. CONCLUSION The anatomic three layers were preserved in our method, thus it is better than the traditional methods. The caudal septal cartilage should be used as the perfect material in rhinoplasty.

OBJECTIVE: To investigate the correlation between allergic rhinitis and obstructive sleep apnea-hypopnea (OSAHS) syndrome in children. METHOD: (1) According to medical history, physical signs, skin-prick test, serum sIgE, endoscopic examination and polysomnography, the incidence of allergic rhinitis was confirmed in 574 cases of childhood obstructive sleeping apnea-hypopnea syndrome in our hospital between July in 2008 to June in 2010. (2) Effects of anti-allergic drugs were observed on 78 children with OSAHS and allergic rhinitis meanwhile. RESULT: (1) 258 cases of allergic rhinitis were confirmed in 574 cases of OSAHS, accounting for 44.9% of the OSAHS cases and 50.4% of all cases of allergic rhinitis during the same period. Most of them were perennial allergic rhinitis (223 cases, 86.4%), and 72.5% of them were aroused by fungal allergen. Compared with other allergen, statistically significant difference was found (P < 0.05). (2) After receiving anti-allergic drugs regularly for 3 weeks, 40 cases suffering from mild and moderate OSAHS and allergic rhinitis, 3 cases out of 38 cases suffering from serious OSAHS and allergic rhinitis showed satisfactory results, while other cases had little improvement. CONCLUSION Allergic rhinitis is closely related to childhood OSAHS, and perennial allergic rhinitis dominates. The most common allergen is fungal allergen, the second is house and flour dust mites. So for patients of mild and moderate OSAHS with allergic rhinitis, regular anti-allergic drugs can lighten OSAHS effectively and may make patients avoid surgery. Severe OSAHS cases can receive surgical intervention if prior anti allergic therapy fails. Anti allergic therapy should be adopted routinely after tonsillectomy and adenoidectomy in case of hypopnea due to hypertrophy of inferior turbinate or tubal torus in allergic rhinitis.
