OBJECTIVETo analyze the clinical characteristics of elderly patients with spinal tuberculosis and explore its clinical effects with anti-TB drugs alone.

METHODSFrom January 2008 to July 2010, the data of 36 patients with spinal tuberculosis underwent conservative treatment of anti-TB drugs alone were analyzed. There were 19 males and 17 females with an average age of 73.5 years (ranged, 60 to 85). All patients were in the active phase with high ESR and CRP levels and were treated with 3HRZE/6-9HRE (course from 9 to 12 months). According to clinical symptoms, chemical examination, radiological image to adjust drug and depending on VAS score to evaluate pain.

RESULTSAll the patients were followed up from 8 to 24 months with an average of 15 months. Tuberculose of 31 patients healed after chemotherapy from 9 to 12 months and ESR and CRP recovered normally. Levofloxacin and para-amino salicylic acid were used in 4 cases because of 4 cases occurred drug fast for RFP or INH, after 15 months, their obtained healing. Symptom of 1 case got worse during chemotherapy, and surgical treatment were performed, after 3 months, ESR and CRP recovered normally, X-ray and CT showed spinal osteosclerosis and fusion without significant kyphosis and internal fixation loosening. Cobb angle was respectively(17.6+/-2.3) degrees, (18.1+/-2.7) degrees before treatment and last follow-up (P>0.05). MRI showed abscess was absorbed and spinal inflammation subsidised. VAS score was respectively 6.5+/-1.7, 1.4+/-0.5 before treatment and last follow-up (P<0.05). Seven patients had complications relating with drug adverse reaction,after discontinuation and treated with clinical symptom,the patients recovered normally.

CONCLUSIONAnti-TB drugs alone can obtain satisfactory effects in treating early senile spinal tuberculosis, but strict supervision and individual administration should not be disregardful.

Dengzhan Shengmai capsule, as a compound Chinese patent medicine, consists of four herbs: Herba Erigerontis, Ginseng, Ophiopogon, and Schisandrae Chinensis Fructus, and contains significant components of flavonoids, lignans, saponins, and organic acids. It is widely used clinically to treat cerebrovascular diseases such as chronic cerebral hypoperfusion and dementia with remarkable efficacy. This study proposes a research strategy for multi-component traditional Chinese medicine metabolites based on prediction databases and unfolds the analysis using Dengzhan Shengmai capsule as an example. Using the UPLC-Q-TOF/MS method, the analytical method was established and detected biological samples such as urine, feces, and bile of rats before and after administration based on the prediction of theoretical metabolites of Dengzhan Shengmai capsule. The possible secondary fragment ion information of metabolites was identified by comparing the detected results with prediction databases. The metabolites were identified based on the archetypal component mass spectrometric cleavage law and multistage mass spectrometric data. 51 metabolites, mainly flavonoid, organic acid, and lignan constituents, were finally identified from rat biosamples based on 306 theoretical metabolites of Dengzhan Shengmai capsule. This study provides a new strategy for the identification of metabolites in vivo and the analysis of metabolic pathways of TCM. The study complied with the procedures established by the Animal Experiment Ethics Committee of the Institute of Materia Medica, Chinese Academy of Medical Sciences and passed the animal experiment ethics examine (No. 00003645).

The aim of this study was to develop the data element standard directory of traditional Chinese medicine (TCM) clinical pharmacy information, to provide application standards and models of TCM clinical pharmacy for the electronic medical record (EMR).

As a treasure resource of novel drug lead compounds, how to rapidly and high-efficiently screen and isolate active components from natural products is critical. Thanks to its high resolution, high automation and flexible integration, online two-dimensional liquid chromatography has great potential for screening active ingredients from complex matrices by integrating a highly specific bio-recognition process into a two-dimensional liquid chromatography system before, on or after the column separation. This review comprehensively summarized recent developments, applications and shortcomings of online two-dimensional liquid chromatography for natural product screening from different integration modes, including pre-column, on-column and post-column screening methods.

Objective To study the influence of sub-chronically exposure to benzo[a]pyrene (B[a]P)on heat shock protein 70 (Hsp70) expression in rat hippocampus. Methods Forty eight healthy adult male SD rats were randonly divided into 6 groups: blank control, olive control and four B[a]P-treated groups, which were exposed intra-peritoneally to B[a]P at the doses of 0.5, 1.5, 4.5 and 10.0 mg/kg for 90 days. The learning and memory function was measured by Morris water maze. The expression level of Hsp70 and hsp70 mRNA in rat hippocampus were detected by Western-blot and RT-PCR, respectively. Immunohistochemistry was used to examine the Hsp70 expression levels in hippocampus CA1, CA2, CA3, DG regions, which were reflected by average gray values of Hsp70 immunoreactive products measured by image analysis system. Results The results of Morris water maze test showed the escape latencies and total distances of navigation in 4.5 and 10.0 mg/kg B[a]P groups were significantly higher than those in two control groups and 0.5 or 1.5 mg/kg B[a]P groups (P＜0.05).The duration of the third quadrant of the space search experiment in 10.0 mg/kg B[a]P group was significantly lower than those in two control groups and 0.5 mg/kg B[a]P group (P＜0.05). The expression levels of Hsp70 and hsp70 mRNA in rat hippocampus decreased with the B[a]P dose. The expression levels of Hsp70 in 4.5 and 10.0 mg/kg B[a]P groups were significantly lower than those of two control groups and 0.5 mg/kg B[a]P group (P＜0.05 or P＜0.01 ). The expression levels of hsp70 mRNA in 0.5, 4.5 and 10.0 mg/kg B[a]P groups were significantly lower than those in two control groups (P＜0.01) and the expression level of hsp70 mRNA in 10.0 mg/kg B[a]P group was significantly lower than those in other B[a]P groups. The results of immunohistochemistry examination indicated that the average gray values of Hsp70 immunoreactive products in CA1, CA2, CA3, DG regions decreased with dose of B[a]P. Pearson correlation analysis showed that there was a negative correlation between the expression of Hsp70 protein in hippocampus and the average escape latency (r=-0.428, P＜0.05). There was a negative correlation between the expression of hsp70 mRNA in hippocampus and the average escape latency,the total distance of the third quadrant (r=--0.677 and r=-0.594, P＜0.01 ). There was a positive correlation between the expression of hsp70 mRNA in hippocampus and the average total duration of the third quadrant (r=0.597, P＜0.01). Conclusion Sub-chronic exposure to B[a]P could inhibit the expression of Hsp70 in rat hippocampus, which was related to the ability of learning and memory of rats and the inhibition effects did not have the region-specificity.
