ObjectiveTo observe the clinic effect of Xueshuantong in subacute cerebral hemorrhage. Methods60 patients with cerebral hemorrhage were randomly divided into treatment group and control group, each grous 30 cases. The control group, only to conventional treatment, the control group addded Xueshuantong 300mg intravenous drip. On the basis treatment in 7 ～21 days of cerebral hemorrhage both groups were checked the NIHSS score and head CT. Before and after the teatment. ResultsAfter 21days,the hematoma volume in the treatment group was ( 3.3 ± 2. 6) ml, the control group was( 7.2 ± 3.7 ) ml, Treatment group was significantly better than the control group (t =4. 102,P ＜ 0.05 ). NIHSS score of treatment group was (4.7 ± 2.8 ) points, the control group was ( 8.6 ± 3.3 )points. Treatment group was significantly lower than the control group( t =5. 329,P ＜ 0.05). ConclusionXueshuantong could promote the absorption of hematoma and the nerve function recovery in subacute cerebral hemorrhage.

Circulating tumor cells (CTCs) are present in the peripheral blood,and play an important role in the recurrence and metastasis of lung cancer.As the researches about CTCs and targeted therapy move along,it is found that CTCs can be used as a liquid tumor tissue to guide clinical treatment and have a certain significance in the clinical staging and prognosis evaluation of lung cancer.

BACKGROUND:To in vitro isolate neural stem cel s with high purity and uniform biological properties and to establish a complete set of neural stem cel culture system is the basis for neural stem cel research.
OBJECTIVE:To establish an isolation and culture system for neural stem cel s from newborn mouse hippocampus, olfactory bulb and cortex and to analyze the biological properties of cel s.
METHODS:Neural stem cel s were isolated from the hippocampus, olfactory bulb and cortex tissue of newborn Kunming mice by mechanical separation and trypsin digestion. Serum-free culture technology, mechanical pipetting and trypsin digestion were used for subculture of neural stem cel s. 10%fetal bovine serum was used to induce differentiation of neural stem cel s. Neural stem cel s and their differentiated products were identified by
immunofluorescent staining of Nestin, CD133,β-TubulinIII, glial fibril ary acidic protein.
RESULTS AND CONCLUSION:The neural stem cel obtained from newborn mouse hippocampus, olfactory bulb and cortex had the capacity of self-renewal and differentiation which were positive for Nestin and CD133. After induction with fetal bovine serum, neural stem cel could differentiation toβ-tubulinIII or glial fibril ary acidic protein positive cel s that were neurons and astrocytes. This experiment has successful y established the neural stem cel isolation, culture, identification and induction system, providing experimental basis for subsequent studies of neural stem cel s.

In this research,Microtox technology was used to evaluate the comprehensive toxicity of Shen-Fu injection,which was an exclusive product of the pharmaceutical company.Firstly,vibrio fischeri was used as test strain.The best test system and methodology were identified.Under the best test conditions,vibrio fischeri was firstly used in the luminescent bacteria comprehensive toxicity of the exclusive product Shen-Fu injection.The results showed that in the 2 mL reaction system,the best recovery liquid volume was 0.9 mL/ freeze-dried vial,50 μL bacterial suspensions/ sample,the detection time was 10 min after adding bacterial suspensions,the pH was 5-10,the luminous intensity was 800 000-12 000 000 for 10 rin.The RSD of replication experiment and intermediate precision test was ? and ?,respectively,which fitted to the requirements.There was no significant difference on EC50 values among 9 batches of tested Shen-Fu injection (41.07％,RSD ＜ 5％).It was concluded that there was significant concentration-effect relationship between Shen-Fu injection and the toxicity of vibrio fischeri.There was no significant difference on EC50 values among different batches.It indicated that there was small quality volatility among different batches of Shen-Fu injection.The control on product manufacturing was strong.
