Spinal cord injury is a serious disabling disease caused by a series of internal and external factors in the field of orthopaedics and neuroscience, which is a big problem for doctors all over the world. Lithium has been used to treat dipolar disorder for over 100 years. It has been reported that lithium is benefit for brain neuron. The treatment effect for spinal cord injury gets more and more attention. Researches indicate that lithium is benefit for spinal cord injury by protecting neuron,reducing after-injury inflammation increasing the produce and release of neurotrophins, stimulating neurogenesis, enhancing autophagy and inhibiting apoptosis. This article summaries advances in mechanism of treatment for spinal cord injury with lithium by reviewing and analyzing researches. Therapy combined with lithium has a good application prospect.

Nerve injury including peripheral nerve injury and central nerve injury has been a global problem. With the development of technology, many innovative approaches for nerve repair have been tested and some of the results are meaningful. It becomes a hot point that repair nerve injured by biological scaffold (nerve conduit). This article reviewed and analyzed several kinds of biological scaffold materials and microenvironment with better effect in recent years. Some new ideas were raised from the three aspects: appropriate materials, microstructure, and bionic microenvironment. It is better to combine multiple measures and achieve the best effect. In addition, nerve scaffold have a bright future in repair of central nervous system.

OBJECTIVETo explore the value of the application of oil red O staining in spinal cord injury (SCI) of rats.

METHODSWith simple randomization, 24 Spargue-Dawley male rats were divided into normal control group including 6, and SCI group including 18. Spinal cord was transected at spinal lever T10 to build SCI model. Six rats of SCI group were sacrificed randomly at 1, 2, 4 weeks after surgery. After the spinal cord tissue sections were made, oil red O staining methods were used to observe the changes at the end of transected spinal cord. Images were analyzed by Image-Pro Plus 6.0 and SPSS 20.0 software.

RESULTSThe oil red O staining of normal control group showed that white matter surrounded by myelin sheath was clear and obviously distinctive from grey matter. Uneven and strengthened staining in oil O was observed in grey matter of SCI group at 1, 2, 4 weeks post-SCI.

CONCLUSIONIt is a good method to label the myelin sheath in spinal cord and distinct white matter from grey matter by oil red O staining. Analysis of the images showed that lipid may become another target for drugs, which needs more researches.

Objective To explore the clinical manifestation and laboratory examination of chronic diarrhea in children with acquired immunodeficiency syndrome(AIDS) and analyze the reasons that causes the chronic diarrhea in children.Methods Clinical data of 7 patients (male 4 cases,famale 3 cases)with AIDS with manifestation of chronic diarrhea among the 17 cases were diagnosed as AIDS in Beijing children′s hospital from Jan.1999 to Dec.2006.The time of diarrhea,degree of dinrrhea,characteristic of stool,accompaniment symptom,laboratory examination were retrospectively analyzed.Results The average onset age was 6 years old(from 2-9 years old).The average time of diarrhea was 6 months(from 1-16 months).Four cases main complained with chronic diarrhea,3 cases came to the hospital because of fever,cough and wasting;6 cases with diarrhea,7 cases with malnutrition and anemia,5 cases accompanied hypokalemia and metabolic acidosis,6 cases had delay in growth and development,2 cases with abnormal stool routine exam,1 case with positive stool culture of fungi.All patients were with lower CD4,5 cases with lower CD4/CD8.Conclusions Chronic diarrhea is a common symptom in children with AIDS,and usually accompanied by obvious delay in growth and development,malnutrition and anemia,the reasons that causes the chronic diarrhea are consi-dered to be related with both the opportunistic infection and HIV infection.

T lymphoblastic leukemia/lymphoma (T-ALL/LBL) is a kind of lymphoblastic malignant tumors orientated in T-cell line with poor clinical effects. Its molecular genetics is mainly correlated with antigen receptor gene, abnormal chromosome, oncogene activation, tumor-suppressor gene inactivation and molecular pathways. This article will review the latest research progress of the molecular genetics in T-ALL/LBL to explore the index of prognosis and possible therapeutic targets.

Objective To explore the therapeutic effect of low level laser irradiation (LLLI) on cerebral infraction combined with hypertension.Methods Two groups were divided, conventional treatment group and laser irradiation combined with conventional treatment group.LLLI (650 nm, 20 mW, 20 min, twice a day, two weeks therapy) was used by extravascular way in addition to conventional treatment, while control group employed conventional treatment only.Whole blood viscosity, plasma blood pressure, lipid and neurological function were assessed by comparing the index of the two groups.Results Whole blood viscosity, plasma viscosity, whole blood high shear reductive viscosity, hematokit (HTC), erythrocyte deformation index, erythrocyte rigidity index, fibrinogen and blood lipid level of both groups decreased and the decrease of the testing group was more significant than that of control group (P＜0.05 or P＜0.01).Neurological deficit score an blood pressure of both groups showed significant decrease (P＜0.05), and the decrease in blood pressure of testing group was significant than that of the control group (P＜0.05 or P＜0.01).Conclusions 650 nm extravascular LLLI may be effective in treatment of cerebral infraction combined with hypertension, and has a good application prospect.

18 years of age were enrolled. The blood pressure measurements at the wrist were compared with the results obtained by auscultatory measurement on left upper arm. Both measurements were taken 3 times in each person. A total 273 measurements were obtained in 91 participants. The evaluation of the accuracy was assessed by 2 statistical methods. (1)The differences between the 2 devices for a given measurement. (2) The differences between the 2 devices for a given person. Results Method 1 showed the sample mean errors and standard deviation of errors were 0.5?7.1 mm Hg for systolic blood pressure(SBP) and -1.6?6.1 mm Hg for diastolic blood pressure(DBP). Method 2 showed they were 0.5?6.1 mm Hg for SBP and -1.6?5.3 mm Hg for DBP. Blood pressure level and the wrist circumferences had no influence on the measurement errors. Conclusion The HEM-6000 wrist blood pressure device apparently met the AAMI criteria and is valid for patient self-measurement.
