Objective To evaluate the kinetics of peripheral blood cells in DTC patients before and after 131I treatment.Methods A total of 64 patients were divided into 2 groups with different therapeutic doses:high-dose group (3.70-5.55 GBq,n =24) and low-dose group (1.11 GBq,n =40).The WBC,neutrophils (NEUT),lymphocytes (LY),RBC and PLT were counted before operation,before 131I treatment,and on 3 d and 7 d after 131I treatment.One-way analysis of variance and two-sample t test were used to analyze the data.Results The counts of WBC and NEUT in both groups along with the LY in high-dose group varied significantly before,and on 3 d and 7 d after 131I treatment(WBC:high-dose group,(6.30±1.04),(8.86±2.07),(6.59±1.64) × 109/L;low-dose group,(6.65±1.48),(10.17±3.04),(7.17± 1.57) ×109/L; NEUT:high-dose group,(3.75±0.88),(6.42± 1.91),(4.53± 1.54) × 109/L; low-dose group,(3.88±0.90),(7.12±2.77),(4.40±1.17) × 109/L;LY:(2.11±0.67),(2.06±0.74),(1.59±0.49) × 109/L;F values:3.88 to 30.20,all P<0.05).The counts of WBC and NEUT in both groups were significantly higher on 3 d after 131I treatment than that before treatment (all P<0.05).The counts of WBC and NEUT in both groups along with the LY in high-dose group decreased significantly on 7 d compared to that on 3 d after 131I treatment (all P<0.05).The counts of LY in high-dose group also significantly decreased on 7 d after 131I treatment than before treatment(P<0.05).The counts of RBC before 131I treatment and LY on 7 d after 131I treatment were significantly different between the 2 groups(t=2.36,-4.30,both P<0.05).Compared with the counts before operation,LY,RBC and PLT were significantly higher (t values:from-4.92 to-2.45,all P<0.05) during hypothyroid state induced by thyroxine withdrawal before 131I treatment.Conclusions Short-term kinetics of WBC and NEUT present as an increase first followed by a decrease after 131I treatment; while LY of high-dose group presents as a gradually decrease.Hypothyroid state induced by levo-thyroxine withdrawal leads to increased counts of LY,RBC and PLT before 131I treatment.

N6-(2-Hydroxyethyl) adenosine, HEA (1), an active ingredient isolated from cultured mycelia of cordyceps species which is a famous traditional tonic in China, showed brain protective, sedative hypnotic activity in pharmacological tests. In order to explore novel non-benzodiazepine sedative-hypnotic agents, HEA was treated as the lead compound. Twenty three target compounds were designed and synthesized. Their chemical structures were characterized by 1H NMR, MS and elemental analysis. Pharmacological test in vivo showed that target compounds 8, 4, 13 were more active than HEA on locomotor and gasping activities of mice. Structure-activity relationships showed that the ribose moiety at N-9 position of adenine base was critical for activity.

Objective To investigate the effects of intranasal administration of heparin-binding epidermal growth factor-like growth factor (HB-EGF) on expressions of nestin and caspase-3 in the perihematomal tissue after intracerebral hemorrhage in rats. Methods A total 36 adult male Sprague-Dawley rats were randomly divided into 3 groups: an HB-EGF group, a control group, and a sham operation group (n = 12 in each group). Then they were further divided into 4-, 7-, and 10-day subgroups (n = 4 in each subgroup). A model of intracerebral hemorrhage was induced by injecting type Ⅳ colagenase. At 1 to 3 days after modeling, the HB-EGF group was intranasaly administrated HB-EGF. The control group was administrated the same volume of saline. The Bederson score was conducted at the corresponding time points and the rats were sacrificed after the forelimb placing test. Immunohistochemistry was used to detect the expression of nestin and caspase-3 in the perihematomal tissue. Results The sham operation group did not have neurological deficits. The Bederson scores (P < 0. 05) and the result of forelimb placing test (al P < 0. 01) at day 4 and 7 in the HB-EGFgroup were better than those in the control group. There were no significant differences at day 10. At day 4, 7, and 10, the number of nestin positive cels in the perihematomal tissue in the HB-EGF group was significantly more than that in the control group (al P < 0. 05), and the number of caspase-3 positive cels was less than that in the control group (al P < 0. 01). Conclusions Intranasal administration of HB-EGF can improve the early neurological function, upreguate the nestin expression and downregulate the caspase-3 expression in the perihematomal tissue after intracerebral hemorrhage in rats, indicating that intranasal administration of HB-EGF may promote the proliferation of precursor cels and decrease cel apoptosis in the perihematomal tissue.

Objective To analyze the mierosurgery treatment and prognosis of cavernous hemangioma loca-ted in pons. Methods 12 cases with cavernous hemangioma located in ports underwent mierosurgery. 11 lesions lo-cated in dorsal tons were resected through midline suboccipital trans- rhomboid fnssa approach. 1 lesion located in ventrolateral pous was resected with suboceipital retrosigmoid approach. Results All the 12 cavernous hemangiomns were rosected totally and confirmed by the postoperative pathology. Clinical improvement was gained in 6 cases, no change in 3 ,aggravation of facial palsy in 1 ,death in 1. The mean follow-up time was 3 months,and Mill scan dem-onstrated good restoration of brain stem tissue with no recurrence signs of lesion. The symptoms due to the operation recovered to some extent. Conclusion The cavernous hemangioma located in brain stem can be resected safely and effectively given the selection of surgical indication and optimal surgical approach.

Objective To explore the clinical effects of atlantoaxial pedicle screw instrumentation in treatment of intractable atlantoaxial dislocation in children. Methods A total of 7 patients with intractable atlantoaxial dislocations were treated with aflantoaxial pedicle screw instrumentation plus atlantoaxial bone grafting from June 2002 to January 2001. Results The dislocation in all patients reached complete reduction, with no complications. All patients were followed up for average 10 months (8-14 months). Radiographs showed successful bone fusion in all patients. Conclusion Atlantoaxial pedicle screw fixation and fusion is an effective method for treatment of intractable atlantoaxial dislocation in chil dren.
