Objective To investigate the diagnostic value of contrast enhanced ultrasound in breast cancer. Methods Thirty-six cases including 51 typical and 22 atypical breast cancer were examined with injecting contrast agent before operation. The enhanced charaters of perfusion pattern, enhanced level, and modes were observed and reanalyzed when pathology was got. Results There was no statistical meanings in perfusion pattern, enhanced level and mode between typical and atypical breast cancer. They all enhanced like branch or annulus with high lever and there were 3 enhanced modes:"fast in slow out"(48% ,35/73) ,"lastly fast in slow out"(44% ,32/73) and "same in same out"(8% ,6/73). Conclusions The enhanced modes of breast cancer showed "fast in slow out" , "lastly fast in slow out"and "same in same out", enhanced like "branch or annulus" and high level enhanced. Contrast enhanced ultrasound can increase the diagnostic accuracy in the early stage of breast cancer.

BACKGROUND:Currently, modified laminoplasty with C7 spinous process and muscle attachment points reserved and C2, C7 decompressive laminectomy can reconcile both ful decompression and structure stability. With early isometric neck muscle exercise, it can enhance cervical dynamic and static force balance and maintain the stability of the cervical spine.
OBJECTIVE:To investigate the clinical effects of modified cervical laminoplasty with postoperative isometric neck muscle exercise on cervical spondylotic myelopathy patients.
METHODS:114 patients with cervical myelopathy were separately performed traditional cervical laminoplasty (control group), modified cervical laminoplasty (modified group), modified cervical laminoplasty, and neck muscle isometric exercise (combined group). Fol ow-up was conducted for 24 months.
RESULTS AND CONCLUSION:(1) Cervical Japanese Orthopaedic Association score, cervical Neck Disabilitv Index scores and the incidence of axial symptoms:There was no significant difference in the Japanese Orthopaedic Association score of three groups at 6, 12 and 24 months after surgery. At 6, 12 and 24 months after surgery, Neck Disability Index scores and constituent ratio of axial symptoms were better in the modified group than the other groups (P<0.05). (2) Results show that modified cervical laminoplasty with isometric neck muscle exercise can get better clinical results in the treatment of cervical myelopathy.

Objective:To study the positive expression rate of M2 subtype of macrophage cell surface molecules and the inflammatory factors of PPS in IL-4-induced M2 macrophage.Methods:The experiment was divided into 5 groups:blank control group, Model group,PPS groups(50 μg/ml,100 μg/ml and 200 μg/ml).The expression of CD206 and CD23 was used as bio-maker to confirm IL-4 induced macrophages by treating RAW264.7 with 20ng/ml of IL-4.IL-4 induced RAW264.7 cells were treated with PPS of 50μg/ml,100μg/ml and 200μg/ml for 24 h.Then the expression of CD206,CD16/32 and CD40 were analyzed by flow cytometry, and the mRNA expression of IL-1β,TNF-α,IL-10 and iNOS were detect by qRT-PCR.Results: After treated with IL-4,the positive rate of CD206 of RAW264.7 were high.After treated with PPS ,the rate of CD16/32 and CD40 in IL-4 induced RAW264.7 cells were high ,the expression of CD206 decreased,and the mRNA level of IL-1βand TNF-αincreased.Conclusion:RAW264.7 cells can be polarlized to M2 subtype macrophage by using 20 ng/ml IL-4.PPS enhances the mRNA of IL-1β,TNF-αand the expression of CD40, CD16/32 in IL-4-induced RAW264.7 cells .These results indicate that PPS can induce the M2 subtype to become M1 macrophages, can improve immune function of macrophages.

AIM: To investigate the influence and mechanism of recombinant macrophage migration inhibitory factor(rMIF) on fibroblasts.METHODS: MRC-5 fibroblasts were divided into two groups: the treated group was treated with rMIF(25-100 ?g/L,12 h,24 h or 48 h) and the control was non-rMIF treatment.The activity of proliferation in both groups was investigated and compared by CCK-8 means.Synthesis of collagen in the culture supernatants was detected by the hydroxyproline.The expression of collagen type I mRNA was examined using RT-PCR analysis.The level of collagen type I protein induced by rMIF was quantified by Western blotting.RESULTS: The production of proliferation ratio of fibroblasts treated with 50 ?g/L and 100 ?g/L rMIF at 24 h or 48 h were increased obviously(P

Objective: It is difficult to repair large-area Ⅲ?burn wound in children.Here we introduce the advantages of the back skin donor site in repairing Ⅲ?burn wound in children.Methods: This clinical study included 15 children with Ⅲ?burn,ranging in age from 18 months to 11 years(mean 7.6 years),with the Ⅲ?burn wound area averaging at 12.6% of the total body surface.The back skin donor site was used to repair the wound.The functional site,such as the joint,was preferentially considered if the skin graft was not enough for all the wounds.Results: Most of the skin grafts survived and the donor sites on the back healed very well.The patients were followed up for six months to three years,which revealed that the skin grafts remained soft without dysfunction and the scar hyperplasia was mild on the donor site.Conclusion: The back donor site supplies larger-area skin with good quality.The donor site heals fast.After healing,patients could sleep on back and compress the scar so as to prevent scar hyperplasia,and the scar does not affect the patient's appearance.With all these advantages,the back donor site is a good choice for repairing Ⅲ?burn wound in children.

Objective:To investigate the protective effect of intensity-modulated radiotherapy (IMRT) on salivary gland function in nasopharyngeal carcinoma (NPC) patients. Methods:In total, 101 NPC patients who were admitted from March 2010 to November 2012 were enrolled in this study. The parotid gland, the submandibular gland, and the oral cavity were sketched as the organs at risk (OARs). The patients were treated with IMRT and were evaluated through a face-to-face interview using a dry mouth assessment ques-tionnaire during the follow-up visits at 3, 6, 12, 18, and 24 months. The dose volume histogram of the salivary gland of the patients was also considered. Results:The mean doses (MDs) in the parotid gland were 37.4 and 33.8 Gy in the affected and uninjured sides, respec-tively. Meanwhile, the MDs in the submandibular glands were 51.6 and 45.7 Gy in the affected and uninjured sides, respectively. The MD of the oral cavity was 38.2 Gy. At 6 months after the treatment, the symptom of xerostomia was significantly improved in 77.2%of the patients (78/101). One year later, only less than 5%of the patients complained of having G3 or higher-grade xerostomia. Conclu-sion:With time, xerostomia significantly improved after the radiotherapy. At least one of the V30 to V35 of the parotid gland was≤50.0%, whereas at least one of the V40 to V45 of the submandibular glands was≤66.7%~50.0%. The MD for the oral cavity should be<40 Gy to effectively protect salivary gland function.

Objective To investigated the protective ways of intensity modulated radiotherapy (IMRT)for submandibular gland function in patients with nasopharyngeal carcinoma.Methods From March 2010 to November 2012,101 patients with nasopharyngeal carcinoma were enrolled into study.They were treated with IMRT and evaluated by face to face dry mouth questionnaire during the follow-up of 3,6,12,18,24 and more than 24 months,meanwhile,their dose volume histogram of submandibular gland were taken into consideration.Results The average contralateral median dose and that of ipsilateral submandibular gland were (45.69±7.22) Gy and (51.64±8.20) Gy,respectively,and the V35,V40,V45,V50 were 95.82 ％,69.99 ％,46.90 ％,25.50 ％,and 100 ％,96.50 ％,82.24 ％,60.98 ％,respectively.There were positive relationship between the xerostomia grading of 3,6,and 12 months after radiotherapy and the average dose of submandibular gland or the V35,V40,V45,V50.After 6 month,the xerostomia in 77.2 ％ (78/101) was significantly improved,and after 12 months,less than 5 ％ of patient complained about G3 or more grade of xerostomia.Conclusions When using IMRT in nasopharyngeal carcinoma,it' s necessary to reduce the irradiated volume and the dose of submandibular gland.It is confined that the median dose of contralateral submandibular gland should be less than 40-45 Gy,and V40 or V45 ≤66.7 ％ or ≤50 ％,which can effectively protect the function of salivary gland.

OBJECTIVETo investigate the facial aging analysis of 1200 Han adult people in Dalian with iris diameter, so as to provide reference for facial rejuvenation in Han people.

METHODS1200 facial digital photographs from the second-generation ID card of China were stratified randomly selected as the research sample, excluding facial deformity, tattooing eyebrow, tattooing lid margin, ptosis, lip grain and eyebrow deformity cases, as well as the cases whose join point of upper eyelid and lower eyelid not exposed at the nasal side. These photos were divided into six cohorts: female aged 18, 38, and 68 years old; and male aged 18, 38, and 68 years old, with 200 cases in each cohort. The individual iris diameter was divided into 20 equal parts in each photograph, with each part marked one unit as individual iris diameter ruler. Ten values were made from a horizontal plane between the medial canthus to ten points at one face ( the line between two medial canthus is used as the horizontal line, circumocular and facial soft tissue were measured with individual iris diameter ruler on the photographs), then the results were analyzed with Adobe Photoshop software.

RESULTSThere are statistically significant differences in eyebrow height (36.42 ± 4.22 unit in 18 years old male group, 40.22 ± 6.90 unit in 38 years old male group, 34.83 ± 9.39 unit in 68 years old male group; 37.59 ± 6.72 unit in 18 years old female group, 41.09 ± 5.15 unit in 38 years old female group, 36.84 ± 9.45 unit in 68 years old female group), palpebral fissure height, physiognomic external canthus height, palpebral fissure width, pupil height and other items (P < 0.05).

CONCLUSIONS(1) The brow position rises to the peak level at middle age (38 years old group), then drops down gradually with aging. (2) The physiognomic external canthus moves towards the nasal side and caudal side with aging. (3) Eyeball moves towards caudal side with aging. (4) The soft tissue around bilateral angle of mouth, nasal tip and submaxilla moves towards caudal side with aging. (5) The measurement of individual iris diameter ruler can apply to analyze the aging changes of facial soft tissue, and is more suitable for the case when facial photographs are taken at different distances.
