The authors presented in the paper the following subjects: a description of risk exposures commonly found in drug clinical trials; risk types in terms of the personnel organization of ethical review boards, and the composition of the ethical review board members, as well as ethical training, ethical review procedures and supervising of the ethical review. To avoid these risks, an analysis is made on the causes of ethical review risks, and recommendations are proposed on international certification, reform of ethical review board setup, greater efforts on training, introduction of ethical supervision and ethical acceptance procedure.

Objective:To discuss the distinctive clinical manifestation of primary aspergillus laryngitis.Method:Six cases of primary aspergillus laryngitis in our department were reviewed,among which 3 cases were diabetes patients,and were laryngeal mucosal barrier impairment.2 cases were smoking, 2 cases were over use of voice and 1 case were gastro-pharyngeal reflux . Refractory hoarseness was the main clinical manifestation of all patients. The prophase treatment with antibiotics and glucocorticoid should breakdown the balance of flora and exacerbate the disease.Result:Stop using antibiotics and glucocorticoid and alter to oral administration of itraconazole in 2 to 4 weeks after final diagnosis can effectively cure the disease. No recurrence was found in 6 month to 4 years follow up.Conclusion:Diffuse hyperemia ,pachynsis and scattered lamellar leukasmus of vocal cord were the characteristic physical findings of primary aspergillus laryngitis.Pathology is the major means to get the final diagnosis. Oral administration of itraconazole could be effective.

The following measures have been taken with improved teaching effects in our recent practice of lemological teaching Firstly,we adjusted our teaching scope from classical communicable diseases to infectious diseases and brought the newest progress into our contents.Secondly,we adopted rich and colorful teaching methods to boost the students' learning interest.Thirdly,the students' clinical capabilities have been emphasized in our lemological examination.And lastly,multimedia has been employed to display our contents more actively.

Objective To discuss the molecular structures and functions of Alu repeats,and its relationships with malignant tumors. Methods Advances in molecular biology and oncology of Alu repeats in recent years had been reviewed. Results Homologous recombination between Alu repeats may result in various genetic exchanges,including duplications, deletions and translocations,cause a series of malignancy alteration by activating some oncogenes. Conclusion Alu repeats as a sort of multifunction regulatory sequences may play an important role during the carcinogenesis and progression of some tumors.

砄bjective:To elucidate the effects of gradually induced occlusal disorder on the expression of TGF ?1 in temporomandibular condyle of monkey. Methods:In a monkey after extraction of right upper first molar and left lower first molar, a fixed orthodontic appliance was used to cause the adjacent teeth inclined to the space and to occlude with opposite in coordinately. Another monkey was used as the control.8 months later, the animals were sacrificed and bilateral temporomandibular condyles were examined with histologic and immunohistochemical methods.Results:In the animal with teeth extraction, degenerative changes were found in anterior medial part of condyles, the thickness of condylar cartilage decreased significantly, especially in the anterior parts of medial and central thirds, and also the intermediate part of medial third ( P

Objective To investigate the relationship between activation of Janus kinase/signal transducer and activator of transcription (JAK/STAT) pathway and multiple organ dysfunction in rats with sepsis. Methods Using a sepsis model produced by cecal ligation and puncture (CLP), 98 male Wistar rats were randomly divided into normal control group (n=10), CLP group (n=40), AG490 (JAK2 inhibitor) treatment group (n=24) and rapamycin (RPM, STAT3 inhibitor) treatment group (n=24). At serial time points, the animals in each group were sacrificed, then tissue samples from the liver, lungs, kidneys and small intestine were harvested to detect STAT1/3 activity, pulmonary myeloperoxidase (MPO) and small intestinal diamine oxidase (DAO) activities. Meanwhile, organ function parameters including serum aspartate transaminase (AST) and blood urea nitrogen (BUN) contents were also measured. Results At 2 hours after CLP, STAT1 activities were found to be enhanced rapidly in the liver, lungs and small intestine, peaking at 6-24 hours, but their increase was delayed in the kidneys. Compared with STAT1, STAT3 activities were weaker and detected only in the liver and lungs, with no detectable STAT3 in the small intestine and kidneys. Pretreatment with either AG490 or RPM significantly lowered STAT1 activities in the liver, lungs and small intestine as well as STAT3 activities in the liver and lungs (P0.05). Conclusions These data suggest that abdominal infection can result in intensive activation of STAT1 and STAT3 in vital organs, and they play important roles in the pathogenesis of sepsis. Inhibition of JAK/STAT pathway can attenuate multiple organ dysfunction secondary to CLP-induced sepsis in rats.

Objective To understand the change of erythrocyte immunity and matondialdehyde (MDA) in perioperative patients with mammary cancer. Methods30 patients were divided randomly into two groups:group A(general anesthesia) and group B(epidural block). To estimate the activity of erythrocyte complement receptor I (CR- I ) and the lever of MDA, the venous blood were collected at the time points of before anesthesia, after anesthesia, during operation, and on the 1st, the 3rd, the 5th postoperative day. ResrltsCompared with before anesthesia, the RBCC3bRR, RBCCaR and RFER in group A were decreased statistically at the time points of after anesthesia, during operation, and on the 1st, the 3rd postoperative day(P ＜0.05 or P ＜0.01). Above mentioned index in group B were reduced significantly only during operation and on the 1st postoperative day. Between two groups, above mentioned index in group A were lower than those in group B(P＜0.05).Compared with before anesthesia, RFIR and MDA in group A were higher at the time points of after anesthesia, during operation, and on the 1st, the 3rd postoperative day(P＜0.05 or P＜0.01).but above mentioned index in group B rose only on the 1st postoperative day.CR- I and MDA in two groups restored to the lever of be fore anesthesia on the 5th postoperative day. ConclusionThe perioperative immunological function of erythrocyte is obviously depressed by general anesthesia and epidural block, especially the former. This depression is relevant to the disorder of erythrocyte immunity regulating function and the lever of plasma MDA.
