Biliary atresia (BA) is one of the most serious pediatric surgical digestive system diseases with progressive liv?er bile duct inflammation and fibrous obstruction. Currently, the etiology of BA is not clear. It may be associated with genetic predisposition, viral infections and immune injury. Now many scholars believe that it was resulted from multiple factors. Among them, the theory of immune-inflammatory is supported by most scholars. Now the mechanisms of CD38, CD138 and IgG4 in autoimmune liver disease were reported in literature. BA and other autoimmune liver diseases are similar in terms that both inflammatory and immune responses plays irreplaceable role during disease development. Therefore, this article briefly review the role of CD38, CD138 and IgG4 in the inflammation-immunity of BA.

AIM: To investigate the clinical safety and effectiveness of the two kind of bandage contact lenses: Senofilcon A (Johnson & Johnson Acuvue Oasys) and Balafilcon A ( Bausch& Lomb pure vision ) after laser - assisted subepithelial keratectomy (LASEK).
METHODS: Thirty - eight patients (76 eyes) who had undergone the LASEK were divided into two groups. One group of patients wore Balafilcon A, the other group of patients fitted with Senofilcon A. The lenses were worn continuously for 7d. This was a seven - day experience and the patients scored for the symptom of the eyes (sore eyes, foreign body sensation and tearing) on the third day and the seventh day. Both of the two groups of patients taken off the soft contact lens on the seventh day and let their vision and corneal staining checked.
RESULTS: The symptoms of eye sore and tearing of the two groups patients were different. The patients who wore the Senofilcon A were better. The pain of eyes were also different at 3 and 7d after surgeries(Z = - 4. 146, P =0. 000; Z= - 2. 814, P = 0. 005). The difference on tearing between the two groups at 3 and 7d after surgeries were significant ( Z = -2. 309, P = 0. 021; Z= -3. 276, P= 0. 001). There was no difference on sensation of dryness between the two groups at 3 and 7d after surgeries (Z= -0. 447, P=0. 655; Z= -0. 966, P = 0. 334). After the lenses were taken off, the visual acuity of patients wearing Senofilcon A was better ( t = 3. 800, P = 0. 001 ); corneal staining showed limited spots in 1- 2 quadrants with significant difference (Z= -2. 384,P= 0. 017).
CONCLUSION: The Senofilcon A ( Johnson &Johnson Acuvue Oasys ) and Balafilcon A ( Bausch& Lomb pure vision) bandage contact lenses are safe and effective after LASEK, and the former is better than the latter in epithelial regeneration.

Objective: To investigate the biological behavior and prognosis factors of type B3 thymoma, and evaluate the efficacy of radiotherapy in patients with type B3 thymoma. Methods: A total of 188 consecutive patients with pathologically confirmed type B3 thymoma were treated in Shanghai Chest Hospital from January 2001 to December 2010. According to Masaoka stageing criteria, 35 (20%) were stage, 20 (11%) were stage, 78 (44%) were stage, and 44 (25%) were stage. Myasthenia gravis coexisted in 54 patients. Results: After a median follow-up of 49 months (7-135 months), the 5-year overall survival rate was 84% (100.0%, 89.0%, 86.1% and 59.8% of stages and respectively), and the 5-year progression-free survival rate was 65% (100.0%, 94.0%, 67.3%, and 33.0% of stages, and respectively).The reccurence rate was 22% and the metastatic rate was 7%. In the univariate analysis, tumor size, Masaoka stage, resection margin, radiotherapy and chemotherapy were significantly associated with 5-year overall survival and progression-free survival (P < 0.05). In the multivariate analysis, Masaoka stage, resection margin and radiotherapy were independent prognostic factors of 5-year progression-free survival (P < 0.05). Radiotherapy could improve the regional control rate and the overall survival of Masaoka stages ?-? patients. The intensity-modulated radiation therapy of pleure could probably improve the overall survival of recurrent patients. Conclusion: The major failure mode for type B3 thymoma is the recurrence of pleure. Radiotherapy can improve the regional control rate and the overall survival of the advanced patients. The intensity-modulated radiation therapy may be the best therapy for the postoperative recurrence of pleure. Copyright © 2013 by TUMOR.

OBJECTIVE: To study the application of isokinetic muscle testing in identification of the faked paralysis to provide scientific data for establishing a standard system of muscle strength in forensic medicine identification. METHODS: Fifty-seven patients with bone fracture or nerve damage as damaged group and 128 normal subjects pretended paralysis as faked paralyzed group were included in this study. Isokinetic muscle testing was performed on bilateral knees of all subjects in the two groups. The peak torque (PT) and peak torque angle (PTA) were compared between both sides in each group. The features of torque-time graph of two groups were classified. RESULTS: In the damaged group, the differences of PT between two sides of flexors and extensors were statistically significant (P<0.05), while the dif- ferences of PTA were not statistically significant (P>0.05). In faked paralyzed group, the differences of PT and PTA between two sides of flexors and extensors were both statistically significant (P<0.05). The torque-time graph of damaged knee presented mostly as single lead peak, while torque-time graph of the faked paralyzed knee presented mostly as multiple peaks. CONCLUSION The feature of torque-time graph could be useful to identify the faked paralyzed extremities in forensic authentication.
