The stable and controllable quality of decoction pieces is an important factor to ensure the efficacy of clinical medicine. Considering the dilemma that the existing standardization of processing mode cannot effectively eliminate the variability of quality raw ingredients, and ensure the stability between different batches, we first propose a new strategy for Chinese medicine processing technologies that coupled with individuation processed and cybernetics. In order to explain this thinking, an individual study case about different grades aconite is provided. We hope this strategy could better serve for clinical medicine, and promote the inheritance and innovation of Chinese medicine processing skills and theories.

AIM:To be one of the primary cause injury to multiple sites of ocular of glaucoma which affects over 70 million people worldwide. We applied data mining techniques, linear and the matrix operations, efficiently calculated the network and estimated the possible function of the“node” genes of the retina and optic of glaucoma, in order to provide new thought and method on the pathogenesis of glaucoma.
METHODS: The data in this study is from Gene Expression Omnibus ( GEO ) which belong to Nation Center for Biotechnology Information ( NCBI) , the quality of the raw data CEL files was processed and analyzed by the Expression software which belong to Affymetrix Inc. , Santa Clare, CA, USA. Significant analysis method ( SAM) which base on the T test was used to identified the significant genes. Based on GRNInfer and Gvedit soft we set up gene networks of optic and retina of mice and further more enriched analysis which based on DAVID and MAS3. 0 online software were processed.
RESULTS:The analysis between the group of the optic nerve heads and retinas in different stage of glaucoma showed that the amount of significant different expressed genes in the optic never head group increased significantly comparing with the group of retina in the early stage of glaucoma, the analysis of the genes network construction show that:the node genes of optic nerve heads included Unc13c、Kif5a、TRPM1、PANX; and the node genes of retina include POU4F1, NEFL, BC03870, CALB2. Metabolic pathways enrichment analysis which based on MAS3. 0 online platform show that there was mainly the amyotrophic lateral sclerosis, tyrosine metabolism, melanogenesis, Nitrogen metabolism, Gap junction, Leukocyte transendothelial migration metabolism pathway enriched out in optic nerve head; and there was mainly amyotrophic lateral sclerosis, neurodegenerative disorders, prostate cancer, leukocyte transendothelial migration metabolism pathway enriched out in retina.
CONCLUSION:By understanding bioinformatics result, it seems optic were more sensitive than the retina to high intraocular pressure, and weather high expression of TYrp1 gene can be as a sensitive diagnostic item require more evidence back up. Functional enrich analysis of node gene showed that cytoskeleton reconstructed, molecular motor and nutrients transport function improve in optic; and in retina, the most prominent finding in retina was enrichment function modules were focus on regeneration, repairing and differentiation of cells, which remind that we should reinforce research on reparation of retina of primary glaucoma. Metabolic pathways enrichment analysis show that inflammatory response plays prominent place in optic and retina of primary glaucoma, because of the optic narrow and crowed anatomic shape, nutrient metabolism and substances transfer enrichment modules play an important role in optics of primary glaucoma.

ObjectiveTo explore the prevalence and spectrum of β-thalassemia mutations in Fujian province,and to provide a reference for prenatal diagnosis and genetic counseling in this population.Methods Two thousand three hundred and one blood samples were randomly selected from 9 different areas of Fujian province from May 2008 to December 2010.PCR and reverse dot blot hybridization (RDB) were adopted for detection of the 17 common types of mutation,and the frequency of each genotype of β-thalassemia mutations was calculated.The β-globin gene of unknown positive samples were analyzed directly with DNA sequencing.Results Three hundred and fifty-nine cases were detected with β-thalassemia mutations of the 2301 copy blood samples submitted,and the detection rate was 15.60％ (359/2301).Of the mutated genes,12 different mutations were identified,namely IVS-2-654(C→T),CD41-42(-TCTT),CD17(A→T),-28(A→G),CD27-28(+C),CD26(G→A),CD71-72(+A),IVS-1-1(G→T),CD43(G→T),-29(A→G),initiation codon ATG→AGG and CD36(-C).Mutation frequencies were 46.54％ (175/376),33.24％ (125/376),9.31％ (35/376),5.05％ (19/376),2.13％(8/376),1.33％(5/376),0.80％(3/376),0.27％(1/376),0.27％(1/376),0.27％(1/376),0.53％(2/376),and 0.27％(1/376),respectively.The most common mutations were IVS-2-654 (C→T) and CD41-42 (-TCTT),which accounted for 79.78％(300/376) of total genetic mutations.In addition,a novel β-globin gene mutation CD36 (-C) allele was detected for the first time,the deletion of a nucleotide C at code 36 within exon 2 lead to a frameshift mutation that could result in a premature termination at code 60.Conclusions β-thalassemia mutations in Fujian province are complex with significant genetic heterogeneity.We present for the first time the detection of a new β-thalassemia mutation in the population:CD36(-C),which provides valuable information for genetic counseling and prenatal diagnosis in Fujian province.

OBJECTIVETo investigate the role of Xuebijing injection(XBJI, traditional Chinese medicine), in inhibiting TLR4--NF-kappaB--IL-1beta pathway of myocardial hypoxia/reoxygenation in rats.

METHODSThirty six male SD rats (280 +/- 30) g were randomly divided into six groups (n = 6): normal group (N group), balanced perfusion group (BP group), model group (M group), low dose XBJI group (XBJI(L) group), middle dose XBJI group (XBJI(M) group), high dose XBJI group (XBJI(H) group). By Langendorff isolated heart perfusion device to establish the model of myocardial hypoxia/reoxygenation in rats. ELISA was used to detect the concentration of interleukin-1beta (IL-1beta); Western blot was used to detect the expression of nuclear factor kappa B p65 (NF-kappaB p65) protein and toll like receptor 4 (TLR4) protein; and RT-PCR to determine the expression of NF-kappaB p65 mRNA and TLR4 mRNA;To observe microstructure changes of hypoxia/reoxygenation myocardial by light microscopy.

OBJECTIVETo compare the clinical effects of unilateral pedicle screw fixation (uni-PS) assisted by Quadrant system and bilateral pedicle screw fixation (bi-PS) for the treatment of lumbar degenerative diseases.

METHODSFrom October 2008 to October 2010,102 patients with lower back pain, unilateral lower limb radiating pain or paraesthesia were treated with pedicle screw fixation and lumbar interbody fusion. There were 67 males and 35 females with an average age of 51.5 years ranging from 34 to 69 years. The patients were randomly divided into two groups (group A and group B) according to the internal fixation type. The patients of group A (n=50) underwent with minimally transforaminal lumbar interbody fusion (TLIF) and unilateral pedicle screw fixation with one single cage placement assisted by Quadrant system;and the patients of group B (n = 52) underwent with posterior lumbar interbody fusion (PLIF) and bilateral pedicle screw fixation with one single cage placement. There were no significant differences between two groups in general information (P > 0.05). VAS score and ODI score system were used to evaluate the preoperative and postoperative pain and function recovery. Operative time, volume of blood loss, fusion rate and complication rate were compared and analyzed by statistical test.

RESULTSAll the patients were followed up from 12 to 21 months with an average of 18.2 months. In the group A,operative time and volume of blood loss were (87.6 +/- 25.5) min and (105.7 +/- 27.2) ml, respectively; VAS score of low back pain and leg pain, ODI score decreased respectively from preoperative 7.2 +/- 1.4, 7.9 +/- 1.1, 42.2 +/- 11.8 to 3.2 +/- 0.6, 3.0 +/- 0.7,15.6 +/- 2.3 at one month after operation; the fusion rate was 96.0% (48/50) and the complication rate was 4.00% (2/50). In the group B,operative time and volume of blood loss were (160.3 +/- 20.5) min and (220.6 +/- 25.5) ml, respectively; VAS score of low back pain and leg pain, ODI score decreased respectively from preoperative 7.3 +/- 1.1, 8.1 +/- 0.9, 43.1 +/- 12.0 to 3.3 +/- 0.4, 3.2 +/- 0.3, 14.9 +/- 2.6; the fusion rate was 96.2% (50/52) and the compli- cation rate was 5.77% (3/52). There were no statistically significant differences between the two groups in fusion rate, complication rate, VAS pain and ODI score. Whereas the operative time and blood loss in group A were significantly lower than that of group B.

CONCLUSIONMinimally invasive unilateral pedicle screw fixation is a safe and feasible method for the treatment of lumbar degenerative diseases. It is as effective as the bilateral fixation in lumbar spinal fusion. In addition, it has the advantages of short operative time, less volume of blood loss, high fusion rate, etc.

OBJECTIVETo investigate the antioxidant effect of melatonin (MT) in the rats with phosgene-induced lung injury and its possible mechanism.

METHODSFifty male SD rats were equally randomized into phosgene exposure group, air control group, MT treatment group, dexamethasone (DX) treatment group, and negative control group. All groups except the air control group were exposed to 8.33 mg/L phosgene for 5 min, and the MT treatment group, DX treatment group, and negative control group were injected with MT (10 mg/kg), DX (2.5 mg/kg), and 1% ethanol saline (1 ml/kg), respectively, via the caudal vein 1 hour after exposure. The rats were sacrificed 6h later. Then, the wet/dry ratio of the lung, the total protein content and neutrophil count in bronchoalveolar lavage fluid (BALF), and the malonaldehyde (MDA) content and superoxide dismutase (SOD) and myeloperoxidase (MPO) activities in lung homogenate were measured; pathological observation was made on the lung tissue under an optical microscope; the protein expression of inducible nitric oxide synthase (iNOS) and NF-κB in the lung tissue was measured by Western blot.

RESULTSCompared with the air control group, the phosgene exposure group showed significantly increased wet/dry ratio of the lung and total protein content and neutrophil count in BALF (P < 0.01) as well as significantly increased MDA content and MPO activity in the lung tissue (P < 0.05). Compared with the phosgene exposure group, the MT treatment group showed significantly decreased MDA content and MPO activity and significantly increased SOD activity (P < 0.01), and the MT treatment group and DX treatment group showed significantly decreased protein expression of iNOS and NF-κB (P < 0.01).

CONCLUSIONMT has protective effect in phosgene-induced lung injury, and its protective mechanism may be associated with scavenging free radicals and inhibiting expression of iNOS and NF-κB.

The mechanisms by which emodin induces apoptosis and inhibits proliferation of cancer cells remain unclear. In this study, we investigated whether the proapoptotic effect of emodin on human NIH-H460 lung cancer cells and SMMC-7721 liver cancer cells was related to regulating RXR expression and function. MTT assay and DAPI staining were used to detect the anti-proliferative and apoptotic effects of emodin with or without 9-cis-retinoid acid on H460 and SMMC-7721. The reporter assay was used to detect the effect of emodin on RXR homo- and hetero-dimer transactivation. Competitive ligand binding assay was carried out to detect whether emodin could directly bind to RXR. The result showed that emodin could strongly inhibit the proliferation and induce apoptosis of both cancer cell lines, which could be antagonized by 9-cis-RA. The reporter assay showed that emodin could inhibit the transcriptional effect of the homo- and hetero-dimer transactivation of RXRalpha dose-dependently. However, in vitro binding assay did not show that emodin bind to RXRalpha-LBD directly. The findings suggest that exhibition of emodin its anti-cancer activity may be associated with involvement of RXRalpha signal transduction pathways.
