The eighteen incompatible medicaments is the incompatibilities in traditional Chinese medicine (TCM). However, in some special occasion, the incompatible medicaments can also be used in one prescription in the clinical applications. In order to reveal the theoretical basis for applications of incompatible medicaments in prescriptions, we analyzed ancient prescriptions and found that there are contrary Chinese herbal nature combina-tions (CHNCs) which have the same meridian tropism as well as the opposite nature and taste in prescriptions. In clinical applications, one of the non-contrary CHNCs was selected as the main response to syndrome differentia-tion. The contrary CHNCs in the same meridian tropism were used to restrict each other and therefore have the protective effects. The features found in this paper will be beneficial to further research on the rational applica-tion of incompatible medicaments.

The ability of repair and regeneration of central nervous system (CNS) is limited. So many researchers applied themselves to search a valuable cell resource for treating severe diseases of the CNS. Several studies from different laboratories have recently reported that stem cells derived from human umbilical cord blood under certain in vitro conditions can manifest neural features that resemble features of neural-derived cells. In vivo transplantation studies have shown that these stem cells persistently engraft in the CNS, some engrafted cells acquire the characteristics of neurons and glia, and improve functional recovery after central nervous system injury. The existence of stem/progenitor cells with previously unappreciated proliferation and differentiation potential in umbilical cord blood raise the possibility that cord blood may provide an efficient source of cells differentiating into the neural lineage, with a potential to be employed in the therapy of human CNS diseases. The achievement and focuses on the mechanisms and modulation of induction of differentiation and in vitro and in vivo studies in this field was reviewed.

Objective To report clinical and pathological features in a Chinese family with CharcotMarie-Tooth disease type 2A2 (CMT2A2). Methods There were 5 patients (2 male and 3 female) in a family with an autosomal dominant inheritance pattern. The index case was a 36 years old woman. She developed progressive distal limb weakness at the age of 6, with pescavus at the age of 8. Other 4 family members presented with similar symptoms between the age of 3-7. Physical examination showed distal limb weakness and wasting, loss of sensory and contracture in all of them. Nerve conduction velocity revealed non-potential in several motor and sensory nerves in the proband and her son. Sural nerve biopsy was performed on the proband. The sequence of MFN2 gene was analyzed in DNA from 5 patients and 3 asymptomatic members. Results Sural nerve biopsy revealed severe loss of myelinated fibers with few regenerating clusters. Electron microscopy revealed aggregation of mitochondrian in the axons. A R94W mutation in MFN2 gene has been identified in 5 patients, but not in unaffected members. Conclusions We confirmed Chinese CMT2A2. Absent of regenerating cluster in the nerve indicated that MFN2 mutation predominantly resulted in lesions in the neurons.

Microbes that produce Docosahexaenoic Acid were isolated from seawater. 160 strains capable of producing lipids were screened out using Sudan Black B dying method from 280 seawater samples. From 60 strains of microorganisms producing bigger lipid particles, 7 strains of them capable of producing lipids more than 8% were obtained with Soxhlet abstracting method in the first screening. In the secondary screening from 10 strains with high lipids yield, strain 7-3 capable of producing 15.9% lipids was obtained, in which the content of DHA(Docosahexaenoic Acid)is 45.2%. Strain 7-3 was identified as Brettanomyces based on its morphological properties, cultural characteristics, physiological and biochemical properties.

Objective To discuss the significance of the application of neutrophil to lymphocyte ratio (NLR)combined with prostate specific antigen (PSA)in early diagnosis of prostate carcinoma.Methods 120 cases with surgery treatment of prostate carcinoma were selected as study group,and 120 healthy people were selected as control groups.The NLR and PSA were tested to diagnose the prostate carcinoma.The critical value of NLR in diagnosing prostate carcinoma was evaluated by ROC curves,and the advantages of combination of NLR and PSA were judged. Results By using ROC curves to evaluate the NLR in diagnosis,the critical value was 2.75.The susceptibility, specificity,Youden index,correct index were 0.79,0.85,0.65,0.72.The susceptibility,specificity,positive predictive value,negative predictive value,correct index of NLR combined with PSA in diagnosing the prostate carcinoma were 0.85,0.83,5.00,0.18,0.68.Conclusion The application of NLR has higher susceptibility and specificity to diagnose prostate carcinoma.NLR combined with PSA can improve the susceptibility and specificity of early diagnosis of prostate carcinoma.

A strain of resistance to copper and cadmium with high concentration, named NTG-01, was isolated from soils of DaYe county mineral area in HuBei province. It can resist copper of 4.5mmol/L and cadmium of 2mmol/L , so we can say that it is a important strain used to study the resistance mechanism of copper and cadmium. A series of morphological and biochemical characteristics and sequences analysis of 16S rDNA reveal that it belongs to the bacteria and is gram negative, short rod, flagella around, the size of bacteria is about 0.8?m?2.0?m , V-P result shows positive, methyl-red result displays negative, and glucose can be utilized to produce acid and gas; In addition to, we find that it has the percent 99 homologous to Enterobacteraerogenes by 16S rDNA sequences BLAST analysis, plus the results of morphological and biochemical parameters, it belongs to Enterobacteraerogenes. We can conclude that NTG-01 has higher resistance to many different heavy metals by measuring MICs values of nine heavy metals at last.
