Objective To investigate dynamic change of anterior pituitary hormones (APHs), thyroid func-tion (TF) and genital hormones (GnHs) in patients with traumatic brain injury (TBI) and their clinical signifi-cance. Method APHs, TF and GnH were tested in 93 patients with TBI,who were admitted to Zhejiang Provin-cial People's Hopital from March 2006 to June 2007. Patients with primary injury in the hypothalamic and pituitary regions, as detected by CT and/or MR/examination, as well as those with tumors or immune diseases in the CNS,endocrine or urinogenital systems, were excluded. The clinical data were analyzed according to Glasgow coma scores (GCS), type and degree of injury, and whether there was any secondary cerebral injury. Twenty healthy people acted as controls. The data were analyzed by the Hotelling T2 test and t-tests using SAS 11.5. A P value of less than 0.05 indicated statistical significance. Results The levels of adrenocortieotropic hormone (ACTH),luteinizing hormone (LH) and prolactin (PRL) were markedly higher in all 93 TBI patients than controls, while those of thyroid-stimulating hormone (TSH), thyroid hormone T3,T4 and FT3 were significantly lower in TBI pa-tients in the early stage after injury than in those at follow-up and controls (P<0.05). The ACTH and PRL val-ues reached (33.33±6.86) and (31.74±5.51), respectively, and the LH value was (9.48±1.14) in the secondary cerebral injury group.The TSH value (1.26±0.17) in the brain injury group was significantly lower than those in controls (P<0.05). With the exception of TSH, PRL, testosterone (T) and E2, other APHs were markedly lower in TBI patients at following-up than in controls (P<0.05). The incidence of traumatic hypothala-mus-pituitary insufficiency (THPI) associated with low levels of more than three APHs was 3.2%, while 13.8% of THPI patients showed low levels of at least one APH. The ratio of sick euthyroid syndrome (SETS) was 14.0%. Conclusions A low level of a single APH is the prevalent pattern in THPI patients. Secondary cerebral injury, such as acute high intracranial pressure, brain edema and ischemia after TBI, may be the chief causes of THPI. Early hyperprolactinemia is an important indication for presaging THPI. The dynamic levels of neurcen-docrine hormones can serve as an important index for determining the suitability of TBI patients for treatment with hormone therapy.

Background and purpose: It has been proven that gefitinib can be safely and efficiently used to treat advanced non-small cell lung cancer (NSCLC) as a molecule targeted drug. This research was aimed to investigate the efficacy and toxicity of gefitinib as the first-line therapy for advanced NSCLC. Methods: A total of 34 pathologically-confirmed NSCLC patients who were not willing to receive or tolerate traditional cytotoxic drug chemotherapy were enrolled into the study. Gefitinib was orally administered 250 mg daily until disease progression or the occurrence of intolerable toxicity. Results: The objective response rate of gefitinib was 29.4%. The disease control rate was 61.8%. The rate of symptom relief was 47.1%. The median progression-free survival was 3.0 months. The median overall survival was 10.2 months. One-year survival rate was 35.3%. The objective response rate of nun-smoker was higher than smoker (P=0.023). The disease control rate for the patients with rash toxicity after administration of the drug were higher than those without rash (P=0.005). Logistic regression showed that rash was an independent disease control factor (P=0.003). The most common drug-related adverse events were rash and diarrhea. Conclusion: Gefitinib provided another choice to patients who are unwilling or unable to be treated by chemotherapy.

Objective:To explore the preventive function for sweating gustatory syndrome and esthetic effect of restoring parotid gland area defect by using platysma flap. Methods: Nine patients who underwent parotidectomy and restored parotid gland area defect with platysma flap were analyzed retrospectively in this study. Observed whether there was an incidence of subjective sweating gustatory syndrome and introcession in the operation region. Results: There was no incidence of subjective sweating gustatory syndrome. Moreover, introcession in the operation region was not obvious. Conclusion: Restoring parotid defects with platysma flap can reduce introcession in the operation region. Application of platysma flap as an interpositional barrier between the skin flap and the parotid bed after parotidectomy can reduce the incidence of sweating gustatory syndrome.
