Objective To investigate the clinic technique and effect of treating lumbar disc herniation (LDH) with decompressor and ozone injection combined lumbar traction after surgery.Methods 110 contained LDH patients were randomly divided into two group:decompressor and ozone group,decompressor and ozone combined lumbar traction after surgery group.Under the guidance of CT,fifty-five patients in group A were treated by disc decompression with Decompressor through poster olateral approach,then ozone was injected into the lumbar disc or out side the lumbar disc,and the other fifty-five patients in group B were treated by lumbar traction after surgery that disc decompression and ozone injection same as the group A in once a day and one week of treatment.The theraputic effect was evaluated by comparing VAS,effective rate of therapy before and after treatment.Results The VAS score of two groups at 1,3,7 days between pre-and post-treatment had singificantly different(t =2.159,2.163,2.169,2.167,2.173,2.192,all P ＜0.05).110 case were followed up after 6 and 12 months,The good-excellent rate of therapy in B group 12 months were better than those of A group (x2 =74.23,75.11,all P ＜ 0.05).Conclusion Decompressor combined ozone injection and lumbar traction after surgery is an effective menthod for treatment of the central type mbar disc herniation.

Objective·To investigate the correlation of single nucleotide polymorphism (SNP) of complement factor H (CFH) gene with schizophrenia in Chinese Han population.Methods·The genotype,allele,and haplotype frequencies of 5 SNP loci (rs800292,rs 1061170,rs 10801555,rs 10922096 and rs2019727) in CFH gene were compared between 418 patients with schizophrenia (case group) and 655 normal people (control group) by SNaPshot technique.Results·All SNP loci were well genotyped in the subjects.Correlation analysis showed that rs1061170 locus allele frequency distribution difference between case group and control group was statistically significant (corrected P=0.045),while genotype and allele frequencies of other SNP loci were not significantly different (all corrected P＞0.05).The frequency of haplotype C-A-T-A-A (rs800292-rs1061170-rs10801555-rs10922096-rs2019727) in case group was different from that in control group (corrected P=0.013).Conclusion·The allele polymorphisms of rsl061170 and the haplotype C-A-T-A-A of rs800292-rs 1061170-rs 10801555-rs 10922096-rs2019727 may be associated with schizophrenia in Chinese Han population.

The latest findings of our laboratory showed that Angelica sinensis polysaccharide (ASP) showed a definite effect in regulating the aging of hematopoietic stem cells. Leukemia is a type of malignant hematopoietic tumor in hematopoietic stem cells. There have been no relevant reports about ASP's effect in regulating the aging of leukemia cells. In this study, human acute myeloid leukemia (AML) KG1alpha cell lines in logarithmic growth phase were taken as the study object, and were divided into the ASP group, the cytarabine (Ara-C) group, the ASP + Ara-C group and the control group. The groups were respectively treated with different concentration of ASP, Ara-C and ASP + Ara-C for different periods, with the aim to study the effect of ASP combined with Ara-C in regulating the aging of human acute myeloid leukemia KG1alpha cell lines and its relevant mechanism. The results showed that ASP, Ara-C and ASP + Ara-C could obviously inhibit KG1alpha cell proliferation in vitro, block the cells in G0/G1 phase. The cells showed the aging morphological feature. The percentage of positive stained aging cells was dramatically increased, and could significantly up-regulate the expression of aging-related proteins P16 and RB, which were more obvious in the ASP + Ara-C group. In conclusion, the aging mechanism of KG1alpha cell induced by ASP and Ara-C may be related to the regulation of the expression of aging-related proteins, suggesting that the combined administration of ASP and anticancer drugs plays a better role in the treatment of leukemia .

Objective: The characteristics and differences of the general notice between the Chinese Pharmacopoeia and the Japanese Pharmacopoeia were investigated to provide references and suggestions for the compilation of the Chinese Pharmacopoeia.
Methods: From the perspective of frame structure and main contents, the general notice between the Chinese Pharmacopoeia and the Japanese Pharmacopoeia was compared.
Results: Each volume of the Chinese Pharmacopoeia had its general notice, including 34 to 48 items and 10 to 12 chapters based on different varieties collected in each volume. The Japanese Pharmacopoeia had 49 items not arranged by chapters. There are many differences on the general notice between the Chinese Pharmacopoeia and the Japanese Pharmacopoeia, such as the definitions and expressions of names, determination of appearance, revision rules, risk assessment and quality control conception. The framework of the general notice in the Chinese Pharmacopoeia was clear, the content was specific and the operation was friendly. The term description of the general notice in the Japanese Pharmacopoeia was concise, and some terms need to be implemented under the guidance of professional knowledge.
Conclusion: In light of comparative study, every volume’s general notice of the Chinese Pharmacopoeia has its own characteristics. By integrating advanced analytical technique, combining the requirements with laws and regulations, and optimizing content and terms, all volume’s general notice could be explored to be coordinated and unified.

OBJECTIVETo understand the prevalence of sub-clinical infection of hepatitis E virus (HEV) among blood donors.

METHODSA cluster sampling strategy was used to sample all blood donors from July to August in 2002 in Beijing. Their blood was tested for IgM and IgG antibody against HEV.

RESULTSThe prevalence of anti-HEV IgM among blood donors in Beijing was 1.74%. The rate of abnormal alanine aminotransferase (ALT) in anti-HEV IgM positive donors is significantly higher than anti-HEV IgM negative donors. Among all ALT abnormal donors, 2.68% can be associated with HEV sub-clinical infection. The percentage is similar with HBV but higher than HCV.

CONCLUSIONThere are sub-clinical infection of HEV among blood donors, which is one of the cause of abnormal ALT in the donors.

Objective To study the dynamic changes of cytokines including tumor necrosis factor-alpha (TNF-?),interleukin-6 (IL-6),IL-8 in serum and cerebrospinal fluid (CSF) of asphyxia neonates,and to analyze the relationship between cytokines levels and severity of brain damage and neurological outcome. Methods The concentrations of TNF-?,IL-6,IL-8 in serum and CSF were measured by radioimmunoassay in 63 asphyxia neonates. Neurological development was evaluated at 12 months by children′s developmental scale of china.Results The serum concentrations of TNF-?, IL-6,IL-8 were significantly higher in asphyxiated neonates than those in the controls,and they were correlated with the degree of encephalopathy. The level of serum TNF-? was hig-(hest) at the first day and IL-6 was highest at the third day. There was no marked dynamic changes within 5 days in serum IL-8 level. The concentrations of TNF-?,IL-8 in CSF were higher at the first and the third day.The dynamic changes of IL-6 in CSF were similar in serum and they were positively correlated. The serum concentration of IL-6 in severe brain injury group was much higher than those of normal and mild group.The CSF concentration of IL-6 in severe brain injury group was much higher than that of normal group. The CSF concentration of IL-8 in severe brain injury group was much higher than those of the normal and mild group. Conclusions The concentrations of TNF-?,IL-6 and IL-8 are increased both in serum and CSF in asphyxiated neonates which are correlated with severity of hypoxic-ischemic encephalopathy. Cytokine-mediated inflammatory reactions may participate in the mechanism of hypoxic-ischemic brain injury after asphyxiaion.The concentration of IL-6 in serum and IL-6, IL-8 in CSF are correlated with the neurological outcome.

Neurodegenerative disease is common and frequently occurs in elderly patients. Previous studies have shown that ginsenoside Rg1 was able to inhibit senescent of brain, but the mechanism on the brain during the treatment remains elucidated. To study the mechanism of ginsenoside Rg1 in the process of anti-aging of brain, forty male SD rats were randomly divided into normal group, Rg1 normal group, brain aging model group and Rg1 brain aging model group, each group with 10 rats (brain aging model group: subcutaneous injection of D-galactose (120 mg kg(-1)), qd for 42 consecutive days; Rg1 brain aging model group: while copying the same test as that of brain aging model group, begin intraperitoneal injection of ginsenosides Rg1 (20 mg x kg(-1)) qd for 27 d from 16 d. Rg1 normal group: subcutaneous injection of the same amount of saline; begin intraperitoneal injection of ginsenosides Rg1 (20 mg x kg(-1)) qd for 27 d from 16 d. Normal: injected with an equal volume of saline within the same time. Perform the related experiment on the second day after finishing copying the model or the completion of the first two days of drug injections). Learning and memory abilities were measured by Morris water maze. The number of senescent cells was detected by SA-beta-Gal staining while the level of IL-1 and IL-6 proinflammatory cytokines in hippocampus were detected by ELISA. The activities of SOD, contents of GSH in hippo- campus were quantified by chromatometry. The change of telomerase activities and telomerase length were performed by TRAP-PCR and southern blotting assay, respectively. It is pointed that, in brain aging model group, the spatial learning and memory capacities were weaken, SA-beta-Gal positive granules increased in section of brain tissue, the activity of antioxidant enzyme SOD and the contents of GSH decreased in hippocampus, the level of IL-1 and IL-6 increased in hippocampus, while the length of telomere and the activity of telomerase decreased in hippocampus. Rats of Rg1 brain aging group had their spatial learning and memory capacities enhanced, SA-beta-Gal positive granules in section of brain tissue decreased, the activity of antioxidant enzyme SOD and the contents of GSH increased in hippocampus, the level of IL-1 and IL-6 in hippocampus decreased, the length contraction of telomere suppressed while the change of telomerase activity increased in hippocampus. Compared with that of normal group, the spatial learning and memory capacities were enhanced in Rg1 normal group, SA-beta-Gal positive granules in section of brain tissue decreased in Rg1 normal group, the level of IL-1 and IL-6 in hippocampus decreased in Rg1 normal group. The results indicated that improvement of antioxidant ability, regulating the level of proinflammatory cytokines and regulation of telomerase system may be the underlying anti-aging mechanism of Ginsenoside Rg1.
