Long-term follow-up of hypothalamic-pituitary function in patients with transsphenoidal pituitary herniation and midfacial anomalies.

OBJECTIVE: We wished to determine whether patients with transsphenoidal pituitary herniation were at risk of developing pituitary failure. DESIGN: We followed up hypothalamic-pituitary function annually in patients with midfacial anomalies and pituitary herniation. PATIENTS: Two patients who had transsphenoidal pituitary herniation and midfacial anomalies were included and the literature was reviewed. RESULTS: Both patients became gonadotrophin, TSH and growth hormone-deficient despite neurosurgical repair. CONCLUSION: We conclude that the early diagnosis and neurosurgical repair of transsphenoidal pituitary herniation may prevent central nervous system infection and rhinorrhoea. Surgical repair may not prevent pituitary failure as was evident in both of our cases. Periodic evaluation of the hypothalamic-pituitary axis is essential to determine whether early hormonal replacement therapy is necessary.     

京剧器乐的听力损伤（附55例调查报告）

本文对从事京剧打击乐的55人（110耳）进行了听力调查及动态观察。利用图表进行对比分析，发现110耳中高频听力损伤89耳，占81％；语频听力损伤32耳，占29.1%；其中伴有高频耳鸣78耳，占70．9％。动态观察30人（60耳），均为永久性听阈阈移。高频听力损伤最早出现的频率是4kHz，并见典型“V”谷，符合噪声性聋的诊断。     

恒猴精索内注射长效局麻药后对睾丸和附睾的影响

在13只恒河猴精索内注射长效局麻药后,睾丸发生明显变化;而且给药剂量不同,睾丸曲精小管改变的程度和恢复正常的时间亦不同。睾丸间质细胞无明显变化;睾酮分泌不减少,无毒性反应。对临床男性节育应用及生殖生理研究均具有意义。

Overgrowth of a costochondral graft in reconstruction of the temporomandibular joint.

We report the case of a 3-year-old girl with temporomandibular ankylosis, which was treated with a costochondral graft and required two further resections because the grafted tissue had overgrown.     

Application of median-effect in quantitative analysis of antitumor drugs in vitro

Objective: To analyze quantitatively the synergistic and antagonistic effects of combined oxymatrine (OMT) and 5-fluorouracil (5-GU) on a cell line of human liver cancer (HepG2) with median-effect principle in vitro. Methods: The median-effect principle and MTT method were used in the quantitative analysis of effects of the two drugs. Results: Cytotoxic activity of the individual drugs enhanced as drug concentration increased. As fa=0.41, a CI equal to 1 indicated additivity; fa<0.41, a CI less than 1 indicated synergy; and fa>0.41, a CI greater than 1 indicated antagonism. The sequence of administration did not influence the cytotoxic activity of the combined antitumor drugs. The ratio of drug concentration was a factor that can influence the killing effect. Conclusion: The combined drugs interaction (CI<1) was synergistic at lower concentration and antagonistic at higher concentration. The ratio of drug concentration is a factor that can influence the killing effect. Biography: HE Song(1965–), male, doctor of medicine, associate professor, Chongqing Medical University, majors in gastroenterology.
