Objective To evaluate the protective effect of insulin-like growth factor-1 (IGF-1) on hypoxic-ischemic brain damage (HIBD) in newborn rats. Methods One hundred and twenty 7-day-old Wistar rats were randomly divided into sham control,HIBD,HIBD treated with 0.2 mg/kg RH-IGF-1 ,HIBD treated with 0.066 mg/kg RH-IGF-1,and normal saline control groups. Those groups were further divided into 24 h、 48 h and 72 h groups respectively after damage with 8 rats in each group. The histological feature,levels of glutamate (Glu) and apoptosis,and expression of Bcl-2 protein in brain were observed in each group. Results (1) Level of Glu in HIBD 48 h group (1162.2?108.1) mg/kg and levels of apoptosis in every HIBD groups[24 h: (7.6?1.9),48 h: (12.6?1.2),72 h: (13.8?0.9) %] are significantly higher than those in sham groups of the same time,[Glu: (750.9? 53.4) mg/kg and apoptosis: 24 h: (2.0?0.2)%,48 h: (2.0?0.3)%,72 h: (2.0? 0.2)%] respectively ( P

ObjectiveTo study the protection of Chinese herbs on the ischemic brain of rats. Methods 75 Wistar rats were divided into 5 groups, Group 1 for false operation. For the other four groups, the common carotid artery was exposed then was ligatured and cut off, Group 2 for model. From the 20th hour after operation on,Group 3, 4, 5 were fed with complex prescription of Chinese medicine named Prescription 1, 2 and 3 once a day respectively. 3 hours after taking medicine, Groups 2-5 were put in the hypoxia environment for 1 hours, then taking the medicine for 7 days. On the 7th day after operation,the blood was taken from R. atria then the rats were killed and the whole right brains were cut off. Malonaldehyde (MDA), notric oxide synthetase (NOS) and superoxide dismutase (SOD) in the brain tissue and serum, and calcium in the brain were measured respectively. ResultsThe three prescriptions can decrease the quantity of MDA both in brain tissue and serum and the calcium in brain tissue(P<0.05-0.001).Prescription 1 can enhance the activity of SOD in brain tissue while the others can decrease the activity of NOS. The hippocampus cells show tidy, and the number of the necrotic cells decrease greatly among them, Groups 4 and 5 are better than Group 3.Conclusions Prescriptions 1-3 can protect the brain tissue of the rat form ischemic brain injury.

Fingerprint of traditional Chinese medicine (TCM) is in the guidance of the basic theory of TCM, according to the variety and quality of TCM and using a variety of analytical methods and technology, to establish the objective, overall and multi index comprehensive evaluation system. The TCM fingerprint in one of the strategic subjects for TCM modernization. As more and more technologies have been applied to the fingerprint research of TCM, it is sure to play a much more important role in many aspects, such as the quality control of TCM, the researches of efficient components, and the mechanism in TCM, and so on. The fingerprint technology includes many modern technologies such as high-pressure liquid chromatography (HPLC). Corydalis yanhusuo is an ancient TCM, and recent years appears many researches about fingerprint of C. yanhusuo. This paper generalizes the research in progresses in research and analytical methods on fingerprint technology of C. yanhusuo, processed products (vinegar), and painkillers, to provide the scientific basis for fingerprint method and quality control of C. yanhusuo.

Objective To explore the effect of circadian rhythm disorder on cognitive decline and neurologic impairment after traumatic brain injury (TBI) in rats.Methods Rats were subjected to a weight-drop model of TBI,then the rat models were divided into 2 groups ac-cording to the environmental length of day and night ,namely,the whole day group (12 h light/12 h light) and the control group (12 h light/12 h dark).After 14 days,the Morris water maze test and step-down test were carried out to evaluate the memory of the rats in each group . HE staining and immunohistochemistry ( BrdU, Ki-67) were carried out to evaluate the degree of the neurologic impairment of the rats in each group.And the mRNA expressions of Caspase-3,Caspase-9,Bcl-2 and Bax were evaluated with realtime PCR .Results The memory function of the rats in whole day group was significant lower than control group ;the damage degree of the cells in the hippocampus and the cortical lesion volume in whole day group were significant higher than control group ;the cell proliferation rate and newborn cell survival rate in the whole day group decreased significantly compared with the control group ;the mRNA expression of Bcl-2 in whole day group was signifi-ant lower than control group ,and the mRNA expression of Caspase-3,Caspase-9 and Bax in whole day group was signifiant higher than control group.Conclusion Circadian rhythm disorder can worsen TBI-induced cognitive decline and neurologic impairment .

AIM: To evaluate the effect of He-Ne laser combined with TDP irradiation in the treatment of herpes zoster ophthalmicus.METHODS: Totally 22 patients (22 eyes) with herpes zoster ophthalmicus were treated by He-Ne laser irradiation combined with TDP (Group A).Another 22 patients (22 eyes) with herpes zoster ophthalmicus (Group B) were treated by medication.The duration of the disease, the incidence of complications, and the time of pain relief were compared between the two groups.RESULTS: The cure rate of Group A was 91%, that of Group B was 73%, there was no significant difference between the two groups (x2=1.375, P>0.05).The average cure time of Group A was 8±2.22d, Group B was 12±1.88d, the difference between the two groups was statistically significant (t=5.22, P<0.05).The complication rate of Group A was 18%, Group B was 59%, the difference between the two groups was statistically significant (x2=6.86, P<0.05).The average pain relief time of Group A was 5±1.23d, Group B was 10±1.34d, the difference between the two groups was statistically significant (t=11.17, P<0.05).CONCLUSION: He-Ne laser combined with TDP irradiation can shorten the treatment time of herpes zoster ophthalmicus, shorten the course of disease, reduce the incidence of complications, relieve pain, with no significant effect on the cure rate of herpes zoster ophthalmicus.

In this paper, the authors make an analysis of the historical literature during the Red Army period of the agrarian revolution war, dealing with the situation of traditional Chinese medicine in the Red Army. During that time the Red Army had created revolutionary medical hospitals, gathering herbal medicine, growing herbal plants and producing Chinese medicines. At the same time the Red Army paid great attention to enriching Chinese medicine, cultivating practitioners and treating and preventing diseases using traditional Chinese medicine. During the Red Army period there was an extreme lack of medical facilities; traditional Chinese medicine played an important role in ensuring the fighting capabilities of the Red Army units. Looking back at the Red Army period, the development of our tradition can be seen, which enables future development of traditional Chinese medicine, as well as integrated medicine.
