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.

Eighty-five endophytic fungal strains were isolated from the roots、stems and leaves of Polygala tenuifolia Willd, among which, fifty-two from natural plants and thirty-three from cultivated ones. Sev-enty-six strains were classified as twenty-three fungal genera. The inhibitory activity screening to fourteen microbe were conducted research. The results showed that some endophytic fungi had remarkble inhibitory activities to Bacillus subtilis, Shigella sonnei, Escherichia coli, Candida albicans, Fusarium kyrushuense and they were all belonged to Fusarium, Alternaria, Aphanocladium respectively. All of the endophytic fungi isolated from Polygala tenuifolia showed no inhibitory activities to Staphyloccocus aureus, Salmonel-lae enteritis, Bibrio parahemolyticus.

The characterization and management of oral and maxillofacial spaces infections in diabetic patients were studied in order to determine the pattern of this clinical condition and formulate a management plan.There were 31 cases with average age of 61 years(s=9);the mean hospitalization time was 14 days(s=6);the average fasting blood glucose level on admission was 10.4 mmol/L.Of the 31 patients 20 were multiple-space infections and 11 were single-space infections.13 patients had major complications during admission.Odontogenic infection was the most common cause of the space infections.Streptococcus viridians and staphylococcus aureus were common organisms(5/19,4/19)identified through pus and/or blood cultures.Early surgical incision and drainage,perfect blood glucose control,intravenous antimicrobial therapy,preventing asphyxia and managing major complications are necessary and effective approaches for the management plan.

Euphorbia kansui (EK) is a toxic herbal drug, and often used after vinegar-processing to reduce its toxicity. In present study, a 1H-NMR based metabonomic approach was used to evaluate the detoxification effect of vinegar-processed EK. The water extracts of EK and VEK were administered orally to male SD rats at doses of 9 g x kg(-1) x d(-1) for 1 week, respectively, and one more week observation was further conducted. The control group was orally given with saline. Histopathological studies of liver samples on the 8th and 15th day were conducted, and the metabolites of rat urine and liver were analysed by 1H-NMR. Histopathological studies of liver samples from EK and VEK treated rats showed no negative impacts. In metabonomic analyses of urines, changes of metabolites indicated liver damages, kidney lesions and imbalance of gut microbes in the second week. VEK-treated rats showed a quite lower toxicity compared with EK-treated ones. The present study revealed that the metabonomic approach might be helpful for the evaluation of toxicity of EK and detoxic effect of VEK.

The nuclear transcription factor nuclear factor erythroid 2-related factor 2 (NRF2) plays a crucial role in maintaining cellular redox homeostasis. The aberrant NRF2 signaling confers enhanced antioxidant capacity, which is linked to tumor progression and therapeutic resistance. The current study investigates the biological effects and molecular mechanism of tribbles homolog 3 (TRIB3), a stress-induced protein, in regulating cell survival and apoptosis in lung cancer. This study first performed the RNA sequencing data analysis with 576 lung adenocarcinoma patients from the cancer genome atlas (TCGA) database. The NRF2- antioxidant response element (ARE) signature was enriched in patients with high TRIB3 expression. Dual-luciferase reporter assay and real-time quantitative polymerase chain reaction (PCR) were used to confirm the effect of TRIB3 on the kelch-like ECH-associated protein-1 (KEAP1)-NRF2 pathway. Abrogation of TRIB3 impaired NRF2 transcriptional activity and reduced the expression of its target genes. Moreover, TRIB3 enhanced NRF2 stability via blocking KEAP1-NRF2 interaction. TRIB3-depletion promoted reactive oxygen species (ROS) production, restrained cell proliferation, and enhanced carboplatin-induced apoptosis. In addition, NRF2 overexpression recovered the tumor inhibition effect of TRIB3-depletion. Consistently, TRIB3 failed to modulate apoptosis in NRF2 depletion cells. In summary, this study shows that TRIB3 inhibits the KEAP1-NRF2 interaction and upregulates the transcriptional activity of NRF2, thereby promoting lung cancer cell proliferation and reducing the sensitivity to chemotherapy. Targeting the TRIB3-NRF2 signal axis may become a new strategy for ROS homeostasis and lung cancer treatment.

OBJECTIVETo observe the effects of epimedium herb (EH), a Chinese herb for replenishing Shen, on regulated on activation, normal T call expressed and secreted (RANTES) and monocyte chemotactic protein-3 (MCP-3) expression in lung tissue of asthmatic rats, for further exploring the action mechanism of EH in treating asthma.

METHODSBrown Norway rats were randomly divided into six groups: the normal control group (A), the allergic asthma model group (B), the group of model rat treated with dexamethasone (C), and the three groups of model rat treated with low (0.125 g/mL), medium (0.5 g/mL), high (2.0 g/mL) dose of EH (D, E and F). RANTES and MCP-3 mRNA expressions in lung tissue were tested with Real-time PCR and the serum levels of tumor necrosis factor alpha (TNF-alpha), interleukin-4 (IL-4), and interleukin-5 (IL-5) were measured by enzyme linked immunosorbent assay (ELISA).

RESULTSAs compared with the model group (B), RANTES, MCP-3 expression and TNF-alpha were lower in the 4 treated groups (C, D, E and F, P < 0.05 or P < 0.01); IL-4 was lower in Group C, E and F (P = 0.007, P = 0.047, P = 0.033), while that in Group D was higher than that in Group C (P = 0.012). As for level of IL-5, lowering was shown only in Group C and F (P = 0.003, P = 0.005).

CONCLUSIONApplying EH in the attack stage of asthma can alleviate the airway inflammation by down-regulating the expression of RANTES and MCP-3 in lung tissue.

To investigate the anticancer effects of ring C in 18β-glycyrrhetinic acid (GA), a series of GA derivatives featured with 9(11)-ene moiety in ring C were designed and synthesized. The structures were confirmed by IR, LC-MS and 1H NMR. Their inhibitory effects towards human prostate cancer PC-3 and leukemia HL-60 cell lines were determined. Most of the derivatives displayed stronger antiproliferative activities than GA. Particularly, compound 14 showed promising anticancer activity with the GI50 values of 4.48 µmol · L(-1) and 1.2 µmol · L(-1) against PC-3 and HL-60 cells respectively, which is worth further study.
