2.Clinical Application of Restoring of Short Coronal Cracked Molar with Cutting Titanium Inlay Crown
Tianjin Medical Journal 2014;(5):493-494
Objective To estimate the clinical effect of cutting titanium inlay crown in the restoration of short cracked molar. Methods Sixty-four short coronal cracked teeth were randomly divided into group A and group B. Group A were treated by crown. Group B were treated by titanium inlay crown. The curative effect was evaluated every year and lasted 2 years. Results One year after the repair, there was no significant difference in the achievement ratio between two groups (93.8%vs 100%,χ2=2.064, P>0.05). Two years after the repair, the success rate was significantly higher in group B (96.9%) than that of group A (68.8%,χ2=8.892, P<0.01). The failed cases of group A were treated by cutting titanium inlay crown, showing good retention. Conclusion The retention of a short cracked molar can be improved by means of cutting titanium inlay crowns.

Objective To investigate the clinical manifestations, endoscopic manifestations, histological characteristics, diagnosis and treatment of the primary gastrointestinal melanoma in China. Methods The gender, age, position, endoscopic manifestations, histological characteristics, treatment, prognosis of the primary gastrointestinal melanoma were gathered and analyzed by reviewing retrospectively the data of 2 cases seen at our hospital and 449 cases searched in CNKI from 1983 to 2015. Results The primary gastrointestinal melanoma was mostly seen in the rectum and anus, and secondly in the esophagus. A typical endoscopic finding was a protuberant or nodular tumor, with erosion or dirty surface on it. Most lesions were friable and easily hemorrhagic. The maximum diameters of most lesions, accounted for 83.3 %, were larger than 2.0 cm. The average value of the maximum diameters was (4.79 ± 2.67) cm. Most cases presented brown or black, followed by hoar. However, some lesions presented various colors, such as blue, red, even co-exited color or achromatic color. Preoperative misdiagnosed rate was 73.64 % and 1-year mortality was 54.19 %. Negative correlation was observed between survival time and lesion size, infiltration depth. Positive correlation was observed between lesion size and metastasis infiltration depth. Survival time had nothing to do with metastasis and age. Conclusion The primary gastrointestinal melanoma was highly aggressive, and usually found in the terminal age, usually together with extensive metastasis, misdiagnosed and poor prognosis. Knowing the clinical features, endoscopic manifestations, histological and immunohistochemical characteristics is the key to early diagnosis.

Objective To analyze the MRI features of fibrocystic breast disease (FBD). Methods 39 patients with pathologically proven FBD were retrospectively reviewed. The imaging protocol consisted of pro-contrast imagings and bilateral breast volume im-aging for breast assessme NT(VIBRANT). MRI features were interpreted based on the morphologic and enhancement kinetic de-scriptors defined on ACR DIRADS-MRI lexicon. Results There were 3 types on ACR BI-RADS-MRI lexicon in FBD,including 13 focal mass-type showing malignant enhancement kinetic pattern mostly;15 cyst-type with non-enhancement or mild enhance-ment,of them,1 case with periductal mastiffs showing strong enhancement and rapid up-slope and wash-out mimicking a breast cancer. 6 non-mass type usually showing benign enhancement kinetic pattern. In 5 patients,MRI did not show definite abnormal evi-dence. Conclusion MRI is of significant value in diagnosing FBD.

8.Abnormal activation of Notch1 and T-cell acute lymphoblastic leukemia
Journal of Clinical Pediatrics 2015;33(5):483-485
Abnormal activation of Notch1 plays pivotal roles in the molecular pathogenesis of human T-cell acutelymphoblastic leukemia (T-ALL). Activating Notch1 mutations present in over 60% of the T-ALL patients. However, so far,there is no therapy with little side effects that specifically targets the abnormally activated Notch1 pathway-induced T-ALL. Thepresent study briefly reviewed the effects of abnormal activation of Notch1 in the pathogenesis of T-ALL, as well as the currentapproaches targeting Notch1 and its limitations, thus providing some guidance for the research and development of clinicaltherapies targeting T-ALL.
