BACKGROUND: Recombinant human erythropoietin (rhEPO) is a glycoprotein. Recent studies have demonstrated that rhEPO regulates many functional activities of neural cells. OBJECTIVE: To investigate the effects of different concentrations of rhEPO on proliferation of neural stem cells (NSCs) cultured in vitro. METHODS: Newborn Sprague-Dawley rat NSCs were harvested and cultured with serum-free culture medium containing different concentrations (5, 50, 500 U/mL) of rhEPO and 20 μg/L basic fibroblast growth factors (5, 50, and 500 U/mL rhEPO groups) and serum-free culture medium only containing 20 μg/L basic fibroblast growth factors (control group). After 7 days of culture, the cloning efficiency of NSCs was calculated. After 10 days of culture, neuron specific enolase (NSE)-and glial fibrillary acidic protein (GFAP)-immunoreactive cells were quantified. RESULTS AND CONCLUSION: In the rhEPO groups, cells proliferated rapidly, and the number of NSC microspheres was greater, in particular in the 50 U/mL rhEPO group, compared with the control group. NSCs grew faster in the 50 U/mL rhEPO group than in the control group. The number of NSE-and GFAP-immunoreactive cells was greater in the 50 U/mL rhEPO group than in the control group (P<0.01). These findings suggest that rhEPO promotes the in vitro culture and proliferation of NSCs, in particular 50 U/mL rhEPO.

Current studies show that postoperative adjuvant radiotherapy (PORT)may improve local control and overall survival for Ⅲ A-N2 NSCLC.With modern radiotherapy technology and techniques,the adverse effect of PORT is moderate and tolerated.Besides,modern PORT doesn′t decrease the survival.Inves-tigation concerning postoperative target volume for PORT is rare,so that definite agreement has not been reached.Available informations suggest that clinical target volume should include bronchial stump,involved lymph nodes,ipsilateral hilar nodes,subcarinal nodes and ipsilateral lower paratracheal nodes.

Objective To study the change of estrogen in patients with pulmonary artery hypertension (PAH) secondary to congenital heart disease (CHD). Methods A total of 144 patients with CHD including 36 patients with normal pulmonary arterial pressure as control group, and 108 with PAH were investigated as PAH group. Their pulmonary artery pressure was measured by right heart catheterization and the serum concentrations of estradiol, progesterone, prolactin and follicle stimulating hormone (FSH) were detected by chemiluminescence immunoassay. Results The serum concentrations of estradiol, progesterone, prolactin and FSH in PAH group were significantly higher than those in control group (P<0.05). Multiple regression analysis showed that the concentrations of estradiol, progesterone and prolactin were not correlated with the site of shunt but significantly correlated with physiologic factor including sex, age and menstrual cycle, and the level of mean pulmonary arterial pressure. The correlation coefficient of mean pulmonary arterial pressure to them was 0.607,0.531 and 0.518 respectively. The concentration of FSH was positively correlated with the prolactin and estradiol with a related coefficient of 0.917 (P=0.012) and 0.759 (P= 0.000). Conclusion The estrogen plays an important role in modification of the pulmonary arterial pressure in patients with CHD and PAH.

OBJECTIVE:To establish a method for the determination of dissolution of Xiaocaihu pill,and compare the differ-ence of preparation from different manufacturers. METHODS:Using 0.1 mol/L HCl as dissolution medium,rotating basket method was used to determine the dissolution of preparations. HPLC was adopted to determine the content of baicalin:column was TSKgel ODS C18 with mobile phase of methanol-water-phosphoric acid (65∶35∶0.7,V/V/V) at a flow rate of 1 ml/min,detection wave-length was 280 nm,column temperature was 30 ℃,and injection volume was 5 μl. RESULTS:The linear range of baicalin was 0.488-124.8 mg/L (r=0.999 9);RSDs of precision,stability and reproducibility tests were lower than 2.0%;recovery was 100.14%-104.78%(RSD=1.58%,n=9). The average t50(50% dissolution time)of baicalin was 85.81 min. CONCLUSIONS:The method is simple with good precision,stability and reproducibility,and can be used for the dissolution determination of Xiaocaihu pill. Xiaocaihu pill from different manufacturers shows great differences,both preparation formulation and clinical use should attach importance to the dissolution of solid preparations.
