1.Research progress on mechanism and premedication regimen of taxanes hypersensitivity reactions
Journal of International Oncology 2009;36(3):190-192
Hypersensitivity reactions ( HSRs) are the serious problems of taxanes in the clinical appli- cation. These reactions range in severity from mild flushing and itching to bronchospasm, dyspnea and signifi-cant alterations in blood pressure with loss of consciousness or not, and death in some rare cases. Nevertheless, HSRs are often reported only sporadically in clinical trials or as case reports. The vague or inconsistent termi-nology used to describe these reactions may reflect our poor understanding of their pathophysiology. This article will reviews the advancement of taxanes HSRs.

Objective To measure the course of the mandibular canal in mandibula posterior area by cone-beam computed tomography ( CBCT ) , to provide a theoretical support for implant preoperative assessment. Methods Mandibular data of 65 people measured by CBCT were collected, measured the distance between mandibular canal around the bone wall and analyzed the differences by gender and the differences between the left and the right. Results The average distance of mandibular canal outer edge to the buccal bone plate by former backward in-creased gradually,at least in the area of the mental formen, at largest in the area of the mental foramen after 18 mm. The average distance between mandibular canal inner edge to lingual bone plate by former backward reduced gradually, at largest in the area of the mental foramen,at least in the area of the mental foramen after 18 mm. The average distance between mandibular canal upper edge to alveolar crest by former backward reduced gradually,at largest in the area of the mental foramen, at least in the area of the mental foramen after 18 mm. The average dis-tance between the edge of mandibular canal to the edge of mandible by former backward reduced previous,then in-creased, at least in the area of the mental foramen after 6 mm, at largest in the area of the mental foramen after 18 mm. All the results had no significant statistical differences between the male and the female, and had no significant statistical differences between the left and the right. Conclusion The trajectory of the mandibular canal from front to back is downward first, then upward in the mesial of the first molar in the vertical, and whose from the buccal side to the lingual side. That has significance for assessment before implant in mandibular posterior area.

To discuss the advantages and disadvantages of fibular osteosynthesis and osteotomy in the treatment of tibial fractures. Medical literature was searched for articles concerning “fibular fracture”and“fibular osteotomy”on Medline to have a comprehensive idea of experiences of others. The results of others and of ours were analyzed and interpreted. Fractures of distal tibia and fibula with displaced distal tibial articular fractures were classic indications of fibular osteosynthesis, but distal tibiofibular syndesmosis and stability of ankle joint were seldom affected by the fibular fracture when tibia was fractured. It is not necessary to perform routine osteosynthesis for distal fibula fracture. Fibular osteotomy may be considered as an adjuvant procedure when atrophic nonunion or deformity union of tibia occurs. It is wise in treatment of tibial fractures not to perform fibular osteosynthesis or osteotomy whenever possible.

Objective To detect the expression of apoptotic inhibitor protein Livin in different esophageal epithelial lesions and to analyze the relation between the expression of Livin with pathologic characteristics. Methods The expressions of Livin mRNA and Livin protein were detected by real- time fluorescence quantitative PCR and western blot in 40 patients with different esophageal epithelial lesions including normal, atypical hyperplasia, carcino-ma in stiu and invasive carcinoma. Results The expressions of Livin mRNA were progressively increased from nor-mal to invasive carcinoma( 1.00 ± 0. 00,2.26 ± 0.79,7.24 ± 1.06,12.21 ± 2.47 ). There was statistical signifi-cance in Livin mRNA expression among carcinoma in stiu and invasive carcinoma and normal tissues ( P < 0.05 ). Conclusion The expression of Livin is significantly related to the progression of esophageal cancer,which may be a new target for diagnosis and gene treatment of esophageal carcinoma.

BACKGROUND: It was reported that the reason why the fracture healing become more and more difficult with the increasing age may be associated with the varied gene regulation of bone marrow mesenchymal stem cells differentiation into osteoblast and lipoblast. However, the exact mechanism under it remains poorly understood.OBJECTIVE: To explore the association of the age-related changes on expression of peroxisome proliferator-activated receptor γ (PPARγ) and core binding α1 (Cbfα1) with the age-relatad fracture healing impairment, we studied the expression changes of PPARγ and Cbfα1 during aging fracture healing.DESIGN, TIME AND SETTING: A randomized control animal trial was performed in the Third Xiangya Hospital of Central South University between October 2007 and Febuary 2008. MATERIALS: Six male SD rats of 3 months and the other six of 23 months, randomly-selected, were divided into two groups: the old experiment group (23 months) and the young control group (3 months). METHODS: Transverse osteotomies on the middle-upper parts of left tibiae were performed to the rats, with the self-made extemal mini-fixator implanted there simultaneously. Tractions were taken twice a day (0.2 mm/d) for 14 days from day 2 till day 15 post operation. On day 15 post operation, rats were sacrificed to harvest left tibea samples. MAIN OUTCOME MEASURES: Both imaging examination and histological observation were performed to the fractures of rats. The PPARγ and Cbfα1 expression were detected with reverse transcription-polymerase chain reaction (RT-PCR) technique. RESULTS: All samples were involved in the results analyses. The imaging examination showed that many osteotylus generated between the broken ends of fractures in the young control group; that the bone formation of the young control group was much better than that of the old experiment group. The histological observation showed that large amounts of osteotylus growth occurred to every animal in the young control group and their membrane bone formation was remarkable; comparatively, the osteotylus growth in the old group was weakened dramatically, and only fibrous joints were seen. The RT-PCR detection showed that differences of significance existed in both PPARγ and Cbfα1 mRNA expressions between the two groups, with the much higher Cbfol mRNA expression in the bone marrow of rats in the young group and the much higher PPARy mRNA expression in the bone marrow of rats in the old group.CONCLUSION: Rats of different ages show different fracture healing abilities, i.e. the higher ages, the lower fracture healing abilities. In addition, expressions of PPARγ and Cbfα1 in the bone marrow of rats alter with the increasing age, which indicates that there are certain associations between the changed expression level of the two factors and the fracture healing impartment.

Objective To evaluate the efficacy and safety of low-dose dexamethasone pretreatment regimen in prevention of hypersensitive reaction (HR) related to docetaxel in elderly tumor patients. Methods According to the order for admission and the ratio of 3:2, 91 elderly patients with docetaxel weekly therapy were randomly divided into two groups: experimental group and control group. All patients aged from 65 to 82 years with a median age of 68 years old. There were 54 patients in the experimental group and 37 patients in the control group. In the experimental group, patients received oral dexamethasone 4. 5 mg once daily on 1 day before treatment, the day of treatment and continuing for 3 days after treatment, while patients received 8 mg twice daily in the control group. All patients were scored according to MCIRS by the physician. The side effects were evaluated by NCI-CTCAE3.0. Results Four cases in the experimental group (7.4 %) and three cases in the control group (8. 1%) occurred HR, and there was no significant statistical difference (P=1. 000). Conclusions The low dose dexamethasone is efficient and safe compared with the conventional dose dexamethasone, and there is no significant difference in HR incidence between two groups.
