Objective To outline the classification of spinal tuberculosis based on MRI findings (Southern Medical University classification,SMU classification) and explore its use in the diagnosis,surgical protocols.Methods The MRI data from 230 cases with spinal tuberculosis were analyzed retrospectively.Our classification system was based on clinical and radiological criteria (abscess formation,disc degeneration,vertebral collapse,kyphosis,sagittal index,instability and neurological problems).The surgical strategies were made according with this classification.Results Two hundred and thirty cases with spinal tuberculosis were classified into the 5 types.There were signal change type (type Ⅰ) in 28 cases,abscess formation type (type Ⅱ) in 39,vertebral collapse type (type Ⅲ) in 78,canal compression type (type Ⅳ) in 46 and kyphosis type (type Ⅴ) in 39 respectively.In type I lesion,25 patients had been followed up.Twenty patients were treated medically.Recurrence of tuberculosis was found in 2 cases.Surgical meticulous debridements were done in 5 cases without recurrence.In type Ⅱa lesion,6 patients were treated medically.The other 6 patients underwent surgical meticulous debridement with recurrence occurred in one patient.There was no difference between medical and surgical treatment regarding outcomes in patients with type Ⅰ and Ⅱa lesion.In type Ⅱb-Ⅴ,surgical treatments were carried out according to the pathological changes.There was no difference between medical and surgical treatment regarding outcomes in the patients with type Ⅱb-Ⅴ.Conclusion The SMU classification helps in differentiating the various manifestations of spinal tuberculosis and appears to correlate with the surgical treatment of spinal tuberculosis.We believe that this new classification system can be used as a practical guide in the treatment of spinal tuberculosis.

Based on the transcriptome data, we cloned the open reading frame of IiHCT gene from Isatis indigotica, and then performed bioinformatic analysis of the sequence. Further, we detected expression pattern in specific organs and hairy roots treated methyl jasmonate( MeJA) by RT-PCR. The IiHCT gene contains a 1 290 bp open reading frame( ORF) encoding a polypeptide of 430 amino acids. The predicted isoelectric point( pI) was 5.7, a calculated molecular weight was about 47.68 kDa. IiHCT was mainly expressed in stem and undetectable in young root, leaf and flower bud. After the treatment of MeJA, the relative expression level of IiHCT increased rapidly. The expression level of IiHCT was the highest at 4 h and maintained two fold to control during 24 h. In this study, cloning of IiHCT laid the foundation for illustrating the biosynthesis mechanism of phenylpropanoids in I. indigotica.

There are 250 species of Zanthoxylum (Rutaceae) in the world. This genus distributed in tropical and subtropical regions. Alkaloids are the major and representative ingredients in these plants including quinolines, isoquinolines, and amide alkaloids, with such biological activities as anti-tumor, anti-inflammatory, analgesic, anti-virus, anti-platelet aggregation, anti-bacteria and anti- oxidant. These species have been used for a long time to treat toothache, urinary and venereal diseases, lumbago and rheumatism. This review summarizes the chemical constituents and pharmacological activities from the Z. sppplants, in an effort to the systematic research and application of the alkaloids of this genus.

Objective To observe the effects of Wendan decoction (WD) on depression-like behavior in a rat model of Parkinson's disease (PD) and explore the related mechanism.Methods Rodent model of PD was established by unilaterally lesioning medial forebrain bundle with 6-hydrodopamine.After intragastric administration with WD,the rats's behavior changes were detected by the open field test,sucrose preference test and forced swimming test;the contents of monoamine neurotransmitters in the rat brain were assessed by high-performance liquid chromatography with electrochemical detection.Results Compared with those of sham-operated rats,the horizontal and vertical activities of the PD model rats decreased significantly,and sucrose consumption decreased significantly,but immobility time during forced swimming was significantly prolonged.The contents of dopamine (DA),5-hydroxytryptamine (5-HT) and noradrenaline (NA) in the medial prefrontal cortex (mPFC) and DA in the striatum decreased significantly.After administration of WD for 2 weeks,the immobility time of the PD model rats was significantly decreased,sucrose consumption increased significantly;DA,5-HT and NA levels in the mPFC increased significantly.Conclusion WD improves the depression-like behavior in PD model rats,and the mechanisms may involve the regulation of monoamine neurotransmitters in mPFC.

Objective To screen the antibacterial activity of Chinese traditional medicines against Yersinia pestis.Methods Six Chinese traditional medicines(Coptis Chinesis etc)were selected and extracted with pure water to make a concentration of 1 mg/L.Yersinia pestis strain 201 and EV 76 were used to determine the minimal inhibitory concentrations(MIC)of these selected medicines in vitro with liquid dilution method.Results Three herbs had inhibition effects on the strain 201 and EV76 in different extents,among which Rheum palmatum had the strongest effect and MIC was 0.025 00 mg/L.Furthermore,the Chinese traditional medicine had the same MIC on both strain 201 and EV76.Conclusions Chinese traditional medicines commonly used have inhibiting effect on Yersinia pesti.

OBJECTIVETo analyze the survival status and prognostic factors of patients with liver metastases from colorectal cancer.

METHODSThe survival rate and prognostic factors of 112 patients with liver metastases from colorectal cancer, who had complete follow-up data, were retrospectively assessed by Kaplan-Meier analysis and multivariate regression analysis.

RESULTSThe median survival time of the 112 patients was 18.25 months. The 1-, 2-, 3- and 5-year overall survival rates were 60.8%, 35.0%, 20.3% and 4.8%, respectively. Univariate analysis demonstrated that gender, age, primary tumor site, chemotherapy and pathological types had no significant correlation with the overall survival. But the treatment of primary tumor, time of liver metastasis, gross type of tumor, resection of liver metastases and clinical stage status were all independently related with the prognosis of patients. Multivariate regression analysis showed that resection of liver metastases, gross type of tumor and clinical stage were key factors affecting the prognosis of patients with liver metastases from colorectal cancer.

CONCLUSIONPatients with advanced stage, infiltrative gross type of colorectal cancer should be followed-up closely so that liver metastases from the cancer can be diagnosed and treated early. Resection of both the primary tumor and liver metastasis may improve survival of the patients.
