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.

Background and purpose: Human epidermal growth factor receptor 2 (HER-2) is the member of tyrosine kinase receptor family. Its differential expression plays the key role in choosing targeted drug for breast cancer. This study focused on screening the breast cancer cell clones of different HER-2 expression levels, and studying the bi-ological characteristics of these cells. Methods: Breast cancer SK-BR-3 cells were clonally purified, and the expression level of soluble HER-2 (sHER-2) from the culture supernatant was detected by the ECLIA on ADVIA Centaur CP System. Cell clones with high expression (>50.0 ng/mL), medium expression (15.8-50.0 ng/mL) and low expression (<15.8 ng/mL) of sHER-2 were identified, respectively. This study observed the morphological changes of cell strains with differential expression levels of sHER-2 by cell culture. Besides, biological characteristics were compared by a series of experiments in vitro, such as clone formation, scratch assay, and transwell detection. Results: Compared with normal breast cells, sHER-2 was overexpressed significantly in SK-BR-3 breast cancer cells. Furthermore, the abilities of clone formation, mobility and invasion of sHER-2 high expression cell strain [(51.3±3.4)%, (50.0±0.6)% and (53.5±4.2)%] were signifi-cantly higher than those of sHER-2 medium expression [(42.0±3.7)%, (19.5±3.4)% and (33.2±3.9)%] or sHER-2 low expression [(26.7±2.9)%, (13.6±1.0)% and (28.9±5.4)%], and the differences were all statistically significant (P<0.05). Conclusion: Breast cancer cell strain with high expression level of sHER-2 can enhance cell proliferation, promote cell motility and other biological effects, which may lay the foundation for clinical screening of targeted drug therapies for breast cancer.

Objective To evaluate the application value of dermoscopy in the diagnosis of genital condyloma acuminatum (CA) in men.Methods A total of 122 warts from 66 male patients with suspected genital CA were firstly diagnosed by experienced dermatologists according to macroscopic morphological characteristics of lesions and clinical history of patients.Afterwards,the warts were examined and diagnosed by dermoscopy,and the two diagnosis results were compared with histopathological findings.Results Of 122 suspected warts,100 were diagnosed as CA by naked-eye examination,112 as CA by dermoscopy and 114 as CA by pathological examination.When histopathological findings served as the gold standard,dermoscopy had a sensitivity of 97.4% and a specificity of 87.5%,and naked-eye examination had a sensitivity of 87.7% and a specificity of 100%.Under dermoscopy,most male genital warts were pink (98/114,86.0%) and papillary (98/114,86.0%),and had distinct vascular characteristics (107/114,95.5%),which mainly included pleomorphic vessels (102/114,89.5%) and punctate vessels (98/114,86.0%).Conclusion CA has characteristic structures under dermoscopy,so dermoscopy can be used for the diagnosis of genital CA in men.
