Syringin, chlorogenic acid and 1,5-dicaffeoylquinic acid are three main bioactive ingredients in herbs of Saussurea involucrata with various pharmacological properties, while their contents are very low. In this study, the biosynthesis of syringin, chlorogenic acid and 1,5-dicaffeoylquinic acid in the cell suspension cultures of S. involucrata were regulated by feeding carbon sources and precursors, which resulted in a great increase of the contents and yields of the above three bioactive ingredients. After 16 days of fermentation, the yields of syringin, chlorogenic acid and 1,5-dicaffeoylquinic acid reached 339.0, 225.3, 512.7 mg x L(-1), respectively. Meanwhile, their contents increased up to 67.9, 1.9, 10.6 times of wild medicinal material, respectively. The results provided a solid basis for further studies on application of cell suspension cultures of S. involucrata for large-scale production of bioactive compounds syringin, chlorogenic acid and 1,5-dicaffeoylquinic acid.

Objective Laryngeal and upper esophageal foreign bodies are common diseases, we explored a new and simple method to remove these foreign bodies. Methods The clinical data of 177 patients with laryngeal and upper esophageal foreign bodies from June 2008 to January 2016 were analyzed retrospectively. We used two methods to treat these foreign bodies:130 foreign bodies were directly removed under video endoscopy;47 foreign bodies were removed with suspension laryngoscopy, and video endoscopy was used meanwhile. Result 177 laryngeal and upper esophageal foreign bodies were removed well, without severe complications like esophageal perforation or phyryngeal fistula. Conclusion Removing esophageal and laryngeal foreign bodies with video endoscopy is simple, safe and effective.

OBJECTIVE:
To explore the injury mechanism of the human knee in a traffic accident by establishing a 3D finite element (FE) model.
METHODS:
The FE model, composed of femur, tibia, fibula, patella, meniscus, knee ligaments and surrounding soft tissues, was reconstructed by CT scanning data from a male volunteer. Validation was performed by the lateral impact simulation, and the stress and strain results were obtained to be compared with those previously reported for injury prediction.
RESULTS:
The results derived from the FE model were found to be similar with those previously reported, most of the ligaments and meniscus wounded at 40 m/s collision, which was readily observed.
CONCLUSION
The simulation results generated by FE model can be effectively used for the injury mechanism analysis of initial contact.

Seven meroterpenoids and five small-molecular precursors were isolated from Penicillium sp., an endophytic fungus from Dysosma versipellis. The structures of new compounds, 11beta-acetoxyisoaustinone (1) and isoberkedienolactone (2) were elucidated based on analysis of the spectral data, and the absolute configuration of 2 was established by TDDFT ECD calculation with satisfactory match to its experimental ECD data. Meroterpenoids originated tetraketide and pentaketide precursors, resepectively, were found to be simultaneously produced in specific fungus of Penicillium species. These compounds showed weak cytotoxicity in vitro against HCT-116, HepG2, BGC-823, NCI-H1650, and A2780 cell lines with IC 50 > 10 micromol x L(-1).

OBJECTIVETo study the effect of water extracts of Wolfberry fruit (WB) and Epimedium (EM) on DNA synthesis of the aging-youth 2BS fusion cells.
METHODSHuman embryonic lung diploid fibroblasts 2BS national standard strain, were used as an aging model. Cell denucleation and cell fusion techniques were applied to observe the effect of WB and EM on DNA synthesis of 2BS fusion cells.
RESULTSIn the 0.025 (V/V) WB or EM water extract containing media, 2BS cells could be continuously cultured for 61.0 +/- 2.9 passages and 56.0 +/- 2.6 passages respectively, while in the control group it was only 49.0 +/- 2.6 passages (P < 0.01). After treatment with WB and EM separately for 2 hrs, the aging 2BS cells were denucleated and fused with young 2BS cells. The [3H]TdR incorporation percentage in these treated cells was significantly higher than that in the untreated control cells (P < 0.01).
CONCLUSIONBoth WB and EM can accelerate the DNA synthesis rate of the aging youth 2BS fusion cells and prolong the life span of 2BS cells.

OBJECTIVETo study the effect of bitter-cold herbs easing dampness method (BCHEDM) plus Sanhuang Yilong Decoction (SYD) combined with methotrexate (MTX) on expression levels of interleukin-1 (IL-1), IL-6, and IL-17 in rheumatoid arthritis (RA) patients of accumulated dampness-heat syndrome (ADHS).
METHODSFrom January 2011 to January 2013 recruited were 90 RA inpatients of ADHS at Department of Integrative Medicine on Rheumatoid Disease, General Hospital of Chengdu Military Region. They were assigned to the treatment group (45 cases) and the control group (45 cases) according to the random digit table produced by SPSS 11.5 Software. Patients in the treatment group were treated by heavy bitter-cold herbs plus SYD combined with MTX, while those in the control group were treated by MTX alone. Expressional levels of IL-1, IL-6, and IL-17 in serum were detected by enzyme linked immunosorbent assay (ELISA) before treatment, at week 2 and 4 after treatment. Erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and disease activity score in 28 joints (DAS28) were detected as well.
RESULTSAfter two or four weeks of treatment, ESR, CRP, and DAS28 decreased more in the treatment group than in the control group with statistical difference (P < 0.05, P < 0.01). After four weeks of treatment, IL-1, IL-6, IL-17, ESR, CRP, and DAS28 in the treatment group were all lower than before treatment and those of the control group at corresponding time points with statistical difference (P < 0.01).
CONCLUSIONSYD combined MTX could play roles of improving inflammatory indices within 2 weeks, and inhibiting the expression of IL-1, IL-6, and IL-17 within 4 weeks.

OBJECTIVETo explore the prognostic impact of bone marrow involvement (BMI) and therapy in diffuse large B cell lymphoma (DLBCL).
METHODSThe clinical characteristics and prognosis of 83 DLBCL patients with or without BMI were retrospectively analyzed. The treatment outcome of standard CHOP regimen (CHOP group), intensive-dose regimen (intensive-dose group) and rituximab combined therapy (rituximab group) were compared.
RESULTSThe adverse prognostic factors including LDH elevation, ECOG score > or =2, higher IPI and aaIPI score, B symptom, hepatomegaly, splenomegaly, hemoglobin <110 g/L, platelet <100 x 10(9)/L and serum albumin <35 g/L were more prevalent in DLBCL patients with BMI than in those without BMI. Multivariate analysis showed that BMI was an independent prognostic factor of DLBCL. The 3-year OS and PFS rates in rituximab group were 78.1% and 64.3%, respectively, being statistically higher than that in CHOP group (23.6% and 21.8% respectively, P = 0.000 for both) and in intensive-dose group (33.3% and 25.7% respectively, P = 0.002 and 0.001, respectively). But no difference between the latter two groups (P = 0.411 and 0.694, respectively). For the patients with BMI, the 3-years OS and PFS in rituximab group (57.1% and 57.1%) were statistically higher than that in CHOP group (13.9% and 14.1%) and intensive-dose group (29.5% and 16.8%) (P = 0.029 and 0.012 respectively), respectively and also no difference in the latter two groups (P = 0.226 and 0.376 respectively). In the rituximab group, the 3-years OS and PFS were 86.7% and 67.3% respectively in patients without BMI, being higher than that in patients with BMI (57.1% and 57.1%), but the difference was not statistically significant (P = 0.645 and 0.965 respectively).
CONCLUSIONBMI is a negative independent prognostic factors of DLBCL patients. The rituximab combined chemotherapy can significantly improve the therapeutic effect of the DLBCL, and relieve the negative impact of BMI.
