The severity of ischemic brain injury was closely associated with the mortality and disability of stroke. How to limit ischemic brain injm-y to the greatest extent and promote the recovery of neurological function is one of the most concerned hotspots at present in the field of neuroscience. A large number of studies have shown that a variety of factors involve in the pathological process of ischemic brain injury, in which, the role of T lymphocyte-mediated immune inflammatory response in ischemic brain injury has received increasing attention. This article mainly reviews the role of T cells in ischemic brain injury.

The popularization of reading ancient books on traditional Chinese medicine has been in abasinstate due to their contents , their readers and the reading competence of their readers .The role of media guidance in popu-larization of reading ancient books on traditional Chinese medicine was thus elaborated with the exhibition of ancient books on traditional Chinese medicine in Library of Nanjing University of Traditional Chinese Medicine as an exam-ple, which may provide certain reference for changing the ideas of libraries and popularizing the reading of charac-teristic documents .

Objective To observe the effect of interaction in children speech therapy.Methods 90 cases with children aphasis were assessed with evaluation for delayed speech and language development by Sign-significance (S-S) method made by Chinese Rehabilitation Research Center and dysarthria evaluation, and treated.Results After treatment, all cases had different improvment on their own level and were in the process of rehabilitation care.Conclusion The speech therapy interaction is easy, economical and can stimulate children' interest to learn speech and get the training goal.

Objective To discusses the effect of different nursing methods on anastomotic healing after low colorectal surgery. Methods 60 patient with colorectal cancer undergoing low anastomosis were randomly divided into the experimental group and the control group with 30 cases in each.The experimental group adopted modified nursing care,while the control group received routine nursing care.The defecation times and incidence of complications were observed between the two groups.Results The defecation frequency of the experimental group was less than the control group,and the incidence of rectal stimulation sign,anastomotic fistula and obstruction was less in the experimental group.Conclusions Modifed nursing methods have certain effects on preventing postoperative complications of low colorectal anastomosis.

Objective To explore the diagnosis and curative effect of phenylketonuria(PKU) in Gansu.Methods Fifty-nine thousand nine hundred infants and 118 borderline cases were screened from Oct.1999 to Dec.2006.Three drops of venous blood was collected from the exterior or interior part in the heel,and trickled the venous blood onto the specialized filter paper,which could be formed into 3 bloodstains with the diameter of 0.8-1.0 cm.Phenylalanine(phe) was detected by chemiluminescence method,and PKU was screened by the PKU standard of diagnosis.Infants with PKU had been given low phe food.During the treatment,phe level,physical development and intellectual development were measured regularly.Patients′ body weight,height and head circumference were measured once 1 month.Patients′ intellectual quotient(IQ) were measured every half year(IQ was analyzed by Gesell test).Results were analyzed by SPSS 11.0 software for t test.Results In total,93 patients with PKU were diagnosed and treated.Thirty-six cases were identified by neonatal screening before 3 mouths old.Mental retardation was found in 57 cases before 6 years old.After treatment with low-phe diet,the follow-up for early-treated patients revealed that their physical and mental development were normal,and height,weight and head circumference were in the normal amplitude,and the results of IQ was(92?12)scores.In later treated patients,abnormal behaviors were significantly improved and their developmental quotients were elevated.Before treatment,Gesell value was(57?20)scores;after 12-18 months treatment Gesell value was(70?20)scores.The difference was significant(t=1.705 P

AIM: To evaluate the clinical outcomes of management in younger patients with primary chronic angle-closure glaucoma (PCACG).METHODS: Thirty-eight patients (50 eyes) aged 40 or younger with confirmed diagnosis of PCACG in advanced or late stage who received surgical treatment in Zhongshan Ophthalmic Center from January 2000 to December 2005were retrospectively investigated. All patients underwent trabeculectomy. The mean follow-up was 23.6±7.5 months.Full ophthalmic examinations were performed. The clinical outcomes including clinical presentations, surgical results and complications were evaluated.RESULTS: The mean age of patients was 33.5±6.1 years old. There was a female preponderance (60.5%). The mean axial length was 22.4±3.5mm with 18.0% short axis of eyeball and 14% nanophthalmos. There was 60.0% fiat anterior chamber depth (＜1.9mm). Ultrasonic Biomicroscopy identified that plateau iris was the most common underlying etiology (80.6%). There was a statistically significant difference in intraocular pressure (IOP) reduction postoperativelyvs preoperatively (P＜0.001). Four eyes failed to control IOP and received second filtration surgery. The main postoperative complications included shallow anterior chamber (20.0%) and malignant glaucoma (12.0%).CONCLUSION: The younger PCACG patients in advanced or late stage can be effectively managed by trabeculectomy.They have more frequency of postoperative sustained shallow anterior chamber and malignant glaucoma. Careful ophthalmic examinations, delicate surgical procedures and well-managed technique of complications were suggested on younger PCACG patients.

Objective To investigate the effects of silybin-phosphatidylcholine compound (SPC) on H2O2-induced the production of nitric oxide (NO) and reactive oxygen species (ROS) in mouse macrophage.Methods Macrophage were collected in abdominal cavity of 6-8 week Kunming mouse,and cultured macrophage(2?108 L-1) were divided into control and SPC group randomly.Macrophage in control group were added into the same volume(0.1 mL) of 9 g/L sodium chloride.Macrophage in H2O2 group were added into a single bolus of H2O2 (1 mmol/L H2O2) for 30 min,while macrophage in SPC group were preincubated with different concentration of SPC for 2 h followed by a 30 min incubation with 1 mmol/L H2O2.Immunocytochemistry were used to measure the contents of inducible nitric-oxide synthase(iNOS),NO production was determined by Griess reactive, ROS was determined by DCFH-DA Fluorescence probe.Results The production of NO in H2O2 group markedly higher than that in control group(P

In this study, we investigate the bioaccessibility of heavy metals (Cu, Pb, As, Cd and Hg) in wild Artemisia annua and use target hazard quotients (THQ) proposed by US Environmental Protection Agency to assess the health risk under the heavy metal exposure. The results showed that the bioaccessibility of Cu, Pb, As, Cd and Hg in A. annua are 0.77, 0.66, 0.46, 0.68 and 0, respectively, and that the value of THQ for adults and children were 0.030 and 0.025 calculated by risk assessment model. The results indicated that the heavy metals in A. annua were not able to be completely absorbed by human body and that their contents were in a safe range. In this study, by combining the bioavailability of heavy metal and health risk assessment, we assessed the security of heavy metals of wild A. annua, which will provide reference for the standard of heavy metals for medicinal materials.
