Objective To analyze and explore the clinical features,pathological characters,treatment and prognosis of rectum carcinoid.Methods From January 1997 to January 2010,69 pathologically diagnosed rectum carcinoid cases were collected from Union Hospital of Tongji Medical College,Huazhong University of Science and Technology and other 7 hospitals.The clinical features,pathological characters,treatment and prognosis were analyzed. Results Of 69 rectum carconid cases,there were 36 males and 33 females.The average age was (49.3±12.9) years.The common symptom were hemotochezia,abdominal pain,constipation,diarrhoea and abdominal distension.There were 55 cases with lesions from the anus less than 8 cm and in other patients,lesions from the anus were all more than 8 cm.66 cases were typical carcinoid,3 cases were atypical carcinoid.40 cases underwent the immunohistochemical staining.The common markers for immunohistochemical staining were Syn,CgA and NSE,the positive percentage were 90％ (36/40),75％ (30/40) and 82.5％(33/40) respectively.A total of 24 patients received endoscopic therapy,44 patients had surgery,1 patient who refused surgery received only life support and symptomatic treatment.Conclusion No specific clinical symptoms of rectum carcinoid,and most were typical carcinoid.Lesions confined to mucosa and submucosa could be considered the endoscopic therapy.

With patients' general situation, medication use, occurrence time of adverse drug reaction/event (ADR/ADE), clinical manifestations and prognosis as reference items, a retrospective study was made for 315 cases with ADR/ADE induced by Gastrodin in Chongqing from January 2008 to June 2014, in order to analyze the characteristics of ADR/ADE and provide reference for rational clinical medication. The results showed that among the 315 cases with ADR/ADE, 143 cases (45.4%) were males and 172 cases (54.6%) were females, most of them (74.9%) were aged above 45; 60 cases (19.0%) with ADE were caused by off-label indications and 66 cases (21.0%) with ADE were caused by over dosage; ADR/ADE cases induced by intravenous drip mainly happened within 30 min (85.5%), ADR/ADE cases induced by oral administration mainly happened within 2 h (74.4%), and all of ADR/ ADE cases induced by intramuscular injection happened within 10 min. Totally 593 ADR/ADE cases were reported, which were mainly damages in gastrointestinal system, skin and its adnexa; And 61.9% of ADR/ADE cases were newly reported. It is suggested that medical workers shall learn about the regularity and characteristics of ADR/ADE induced by gastrodin, apply it in clinic with standards, pay close attention to changes of patients' situations and attach importance to the monitoring of ADR/ADE, so as to enhance the safety of medication.

Background:Gastrointestinal carcinoids are prone to be neglected in clinical practice because of the poor specific symptoms in early stage. Aims:To analyze the clinicopathological characteristics,treatment modalities and prognosis of a series of cases of gastrointestinal carcinoids for strengthening the understanding of the disease. Methods:A total of 116 patients diagnosed as gastrointestinal carcinoids by pathology from Jan. 1997 to Jan. 2010 in 8 hospitals at Wuhan were enrolled in this retrospective study. Data on sex,age,major symptoms,diagnostic approaches,treatment modalities, pathological features and prognosis, etc. were collected and analyzed. Results:The most common sites of the gastrointestinal carcinoids were rectum(59. 5%)and stomach(19. 8%);the most common symptoms were abdominal pain,abdominal distention and hematochezia. The positivity rates of immunohistochemical marker NSE,Syn and CgA were 92. 7%,87. 5% and 62. 5%,respectively. The proportion of stomach carcinoids with diameter larger than 2 cm was 73. 9%, and that of rectal carcinoids was only 13. 0%(P <0. 001). Most of the gastric carcinoids(81. 8%)infiltrated into or breakthrough the serosa;the rate of lymph node involvement in gastric carcinoids was significantly higher than that in rectal carcinoids(72. 7% vs. 17. 1%,P<0. 001),while typical carcinoids were less common in stomach than in rectum(60. 9%vs. 95. 7%,P<0. 001). Only one(4. 3%)gastric carcinoid patient underwent endoscopic therapy,while that for rectal carcinoids was 24 cases(34. 8%,P=0. 003). Surgical operation was the main therapeutic method for both gastric and rectal carcinoids. The 3-and 5-year survival rates for rectal carcinoids were 92. 8% and 62. 3%,respectively,and those for gastric carcinoids were 62. 6% and 49. 2%,respectively;there were no significant differences between the two groups(P>0. 05). Conclusions:Gastrointestinal carcinoids enrolled in this study distributed mainly in rectum and stomach. As compared with rectal carcinoids,gastric carcinoids were more advanced in disease stage with poorer prognosis. Regular health checks, strengthening the understanding of the disease,and grasping the specificities of carcinoids distributed at different sites might be helpful for the early diagnosis and treatment of gastrointestinal carcinoids,thus improving the survival rate.

Objective To explore the CT findings of mucoepidermoid carcinoma (MEC) of the tracheobronchial tree and improve the diagnostic accuracy. Methods The CT images, histopathological and clinical data in 24 patients with pathologically proved MEC of the tracheobroncbial tree were retrospectively analyzed. Results The clinical symptoms included cough, sputum, fever, wheezing, chest pain and hemoptysis. The patient was proved to be low-grade (n=19) and high-grade (n=5) MEC histopathologically. One lesion was located in trachea, 6 in main bronchus, 12 in lobar bronchus and 5 in segmental, subsegmental and distal bronchus. The tumor presented as no-invasive endotracheobronchial well-defined round-like nodule (n=13, locating in lobar and higher bronchus) and columnar sharp (n=3, locating in main bronchus), or intra-and-extraluminal well-defined round-like nodule or mass (n=6, locating in lobar and lower bronchus) and irregular mass with invasive pattern (n=2, high-grade type). The density of lesion was similar to the muscule and the calcification within lesion was showed in 4 patients on non-enhanced CT. The lesion had marked enhancement in 17 patients on enhanced CT. Obstructive changes were found in 20 patients. Conclusion MEC of the tracheobronchial tree is usually low-grade malignancy and locates in main and lobar bronchus with no-invasive well-defined airway mass, marked enhancement and calcification on CT.

BACKGROUND: Stable reliable experimental animal models are needed urgently in scar research.OBJECTIVE: Scar animal models of nude mice are evaluated with histological method to define optimal opportunity for using.DESIGN: Randomizly controlled and repetitively measured design.SETTING: Department of Burn, First Affiliated Hospital, Sun Yat-sen University.MATERIALS: The experiment was conducted at the Center for Animal Experiment, Medical College, Sun Yat-sen University between January 2004 and March 2004. Fifteen nude mice aged 4-6 weeks were provided by Center for Animal Experiment, Medical College, Sun Yat-sen University (of either gender with body mass of 15-25 g). Hyperplastic scar was gained from samples of exairesis in patients with burn after healing which is hyperplastic scar for half a year.METHODS: Human hyperplastic scar was grafted at dorsa of nude mice to establish scar animal models. After graft for four weeks, 5 experimental animals were killed every week, and grafts were gained. 100 g/L formalin was used to fix samples for 3 weeks. Picric-sirius red polarized light method was used to detect the graft and clinical materials, and histological feature was observed.MAIN OUTCOME MEASURES: ①Results of film reading of picric-sirius red polarized light method. ②Analytic result of computer image.RESULTS: ①Results of film reading of picric-sirius red polarized light method: The grafts showed the same feature of diffused distribution of mainly yellow and red thick fiber with thin-mesh green fiber under polarized light in every time segment group. ②Analytic result of computer image: In clinicopathological hyperplastic scar, type Ⅰ collagen was about 74%; type Ⅲ collagen accounted for about 26%. In the graft from 4-6 weeks, the contents of type Ⅰ collagen were (74.52 ±0.47)% , (74.43 ±0.53)% ,(74.69±0.63)%, respectively; The contents of type Ⅲ were (25.48±0.47)%, (25.57±0.53)%, (25.31±0.63)%, respectively, which had insignificant difference (P ＞ 0.05 ).CONCLUSION: In the time segment designed by experiment, the feature of graft and clinical material is coincident, which is accorded with the characteristics of hyperplastic scar. The detection of collagen of scar tissue with picric-sirius red polarized light method is a simple effective method for assessing the tissue of hyperplastic scar. Establishing scar models with nude mice is effective and stable.
