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.

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.

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.

To prepare ginseng saponin Compound K with ultrasound-assisted total zymolytic ginseng saponins. The conversion rate was taken as the index to detect the pre-treatment factors such as ultrasonic power and ultrasonic time, as well as the impact of enzymatic factors, such as pH value, temperature, concentration of substrate, dosage of enzyme and reaction time, on the conversion rate. The response surface method was used to optimize the preparation conditions. The enzymolytic products were identified with MS, 1H-NMR and 13C-NMR. The results showed that the optimum conditions of the ultrasound-assisted enzymolysis were 250 W for ultrasonic power, 15 min for ultrasonic time, 5.5 for enzymolytic pH, 50 degrees C for enzymolytic temperature, 36 h for enzymolytic time, 4:5 for enzymolytic dosage: substrate and 1.0 g x L(-1) for concentration of substrate. The relative molecular mass of reaction products was 622.4. Therefore, the nuclear magnetic map verified that the reaction product was rare ginseng saponin Compound K. Under the above conditions, based on the total zymolytic ginseng saponins, the conversion rate of rare ginseng saponin Compound K was 6.91% in proportion to the total of ginsenosides. The process features gentle reaction conditions, high conversion rate and simple and reliable process, which is suitable for industrial production.

Objective To investigate the immunomodulatory effect of mesenchymal stem cells (MSCs) and their role in prolonging allograft survival in rat heart transplantation. Methods Inbred Wistar rats were used as donors, and Fisher 344 as recipients. MSC were isolated from femur and tibia bone marrow of donors and cultured in vitro. Mixed lymphocyte reaction assays were performed to assess the immunosuppressive effects of different concentrations of MSC on allogeneic T cell proliferation. Cardiac allograft model was established and according to different intervention measures recipients were divided into two groups (MSC treatment group and control group) (n=8 in each group). In MSC treatment group, recipients were infused with 2×106 MSC via the tail vein at designated intervals (one week before operation, during operation and consecutive three days postoperation), while in control group, the recipients were treated with Ringer's solution at the same interval& At day 5 posttransplantation real-time PCR was used to detect the changes in the expression of Thl and Th2 cytokine genes in transplanted hearts. Results In vitro allogeneic T cell response was greatly suppressed by MSC in a dose-dependent manner. Real-time PCR revealed that IL-1β,IFN-γ, IL-4 and IL-10 were expressed in MSC treatment group, while IL-4 and IL-10 were not expressed in control group but with significantly higher expression of IL-1β and IFN-γ. As compared with control group, survival of MSC-treated allografts was markedly prolonged as compared with control group (mean survivaldays: 12.4±5.3 vs 6.4±2.0, P＜0.05). Conclusion Intravenous adrninistmtion of MSC can prolong the survival of transplanted heart possibly by induction of allograft tolerance through changing Th1/Th2 balance.
