Rhynchophylla is a Chinese herb commonly used in clinical practice. It's also the primary herb of some famous Chinese herbal compound such as Tianma Gouteng decoction, and Lingyang Gouteng decoction. According the record from many previous materia medica literatures, rhynchophylla should be added later during decoction. Pharmaceutical research showed that rhynchophylla alkaloids were not stable. Which has resulted in many problems in the research and its application. For example, there was not a quantitative determination method in "Chinese Pharmacopoeia" of past and present versions, which seriously impacted its quality control and product application. Firstly, records from previous materia medica literatures and "Chinese Pharmacopoeia" were systematically sorted based on the chemical stability of rhynchophylla. Secondly, pharmaceutical research including chemical compositions and their stability, pharmacological effects, extraction process and quality analysis, was reviewed after reference of literatures published at home and abroad in recent decades. Positive reference and evidence for further research and development of rhynchophylla will be provided in the article.

OBJECTIVETo investigate the effect of paraquat (PQ) on reactive oxygen species (ROS) and neutrophil apoptosis and its possible signal transduction pathways.

METHODSCultured neutrophils were treated with different concentrations of PQ for 6-24 h. The apoptosis rate of neutrophils and ROS content were determined by flow cytometry. The exoressions of nuclear factor kappa B (NF-κB) and Caspase 3 were detected by Western blot. These parameters were checked again after NF-κB and Caspase 3 antagonist were applied.

RESULTSPQ could boost ROS generation and depress neutrophil apoptosis significantly. At the same time PQ could enhance the expression of NF-κB and inhibit the expression of Caspase 3. These effects could be reversed by ROS inhibitor diphenyleneiodonium (DPI) and NF-κB inhibitor pyrrolidinedithiocarbamate (PDTC).

CONCLUSIONPQ is a potent inducer of ROS and can inhibit neutrophil apoptosis by activating NF-κB and surpressing Caspase 3 activity.

OBJECTIVETo compare therapeutic effects of herb-partitioned spread moxibustion and western medicine on chronic nonspecific ulcerative colitis.

METHODSSixty cases were randomly divided into a spread moxibustion group (n = 28) and a western medicine group (n = 32). The spread moxibustion group was treated with herb-partitioned spread moxibustion at lower limb around stomach meridian, abdomen region around Guanyuan (CV 4) and lower Jiaji (EX B 2) points; and the western medicine group was treated with oral administration of Sulfasalazine. Their therapeutic effects were observed after treatment.

RESULTSThe cured-markedly effective rate was 71.4% (20/ 28) in the spread moxibustion group, and 25.0% (8/32) in the western medicine group, the former was better than the latter (P < 0.05).

CONCLUSIONSThe therapeutic effect of herb-partitioned spread moxibustion for treatment of chronic nonspecific ulcerative colitis is better than that of the oral administration of Sulfasalazine with less adverse reaction, and is worth popularizing in clinic.

Objective To investigate the auxoaction and mechanism of CDllc+DCs on psoriasis. Methods CDllc+ DCs in the psoriasis-like lesions were confirmed by immunofluorescence double staining experiments. The CD1lc+ DCs were subcutaneously injected into the neck skin of transgenic mice without disease. The clinical features were observed and assessed with PASI score every day. The ear and back skin were checked by HE stained. At the same time, the T lymphocyte and DCs of bone marrow, spleen, submandibular lymph nodes and blood were analyzed by flow cytometry, and the T lymphocyte in the skin lesions were analyzed by immunofluorescence. The heart, liver, spleen, lungs and kindey were HE stained. Results In the psoriasis-like lesions, about 90％ CDllc+ cells expressed CDllc. HE test showed that the thickness of the skin layer was significant different between the experimental group (ear: 29±4 μm; back: 25±3 μm) and the control group(ear: 11±2 μm; back: 9±1 μm) (P＜0.01). CD3 + CD4+ T lymphocyte cells in the blood of the experimental mice (17.87％) were decreased significantly (P＜0.01) compared with the control group mice (31.77％). The numbers of Thl and Th17 cells from bone marrow, spleen, submaxillary lymph nodes and blood, as the same as CD1lc+DCs from bone marrow and submaxillary lymph nodes, were decreased in the experimental mice compared with the control group mice (P＜0.01). The number of CD4﹢T cells, CD8+T cells, IL-17a+cells and IFN-γ+cells in the skin lesions from the experimental group all were higher than that from the control group (P＜0.01). And the vessels in the lesions of the experimental group were higher than that in the control group (P＜0.01). Conclusions CD1 lc+CD1 lc+DCs may play an important role in the occurrence and development of psoriasis by increasing the T lymphocyte and the blood vessel in the skins of K14-VEGF transgenic mice.

Aim To investigate the effects of curcumol on the contractile activity of isolated duodenal smooth muscle in rats and explore its underlying mechanisms. Methods The isolated duodenum specimens of rats were made. The effects of different concentrations of curcumol on the contraction of isolated duodenal smooth muscle were observed using BL-420F biological and functional experimental system with constant tem-perature perfusion method. A certain concentration of curcumol was combined with atropine,isoproterenol, norepinephrine,calcium-free Krebs solution,verapam-il respectively to observe its effect on smooth muscle contraction. Results Curcumol could stimulate duo-denal smooth muscle in vitro,and increase its contrac-tile amplitude and tension significantly. It could be an-tagonized partly by atropine,isoprenaline,norepineph-rine,verapamil. Conclusion Curcumol can promote the contraction of isolated duodenal smooth muscle in rats,which may be achieved by stimulating M recep-tor,inhibiting α and β receptors,and promoting the extracellular calcium influx.

OBJECTIVETo detect tumor specific chromosome translocations and associated fusion transcripts in paraffin-embedded tissue by interphase fluorescence in-situ hybridization (FISH) and reverse transcription polymerase chain reaction (RT-PCR), respectively, and to evaluate their diagnostic values for Ewing's sarcoma/primitive neuroectodermal tumor (ES/PNET).

METHODSNuclei of the tumor cells and total RNA were extracted from 10 cases of ES/PNET. Interphase FISH was utilized to analyze the EWS gene translocation with a dual color, break apart probe (Vysis company). RT-PCR was used to detect t (11; 22) (q24; q12) and t (21; 22) (q22; q12) fusion transcripts.

RESULTSAmong 10 cases of ES/PNET, the EWS-FLI1 fusion transcript was detected in 8 by RT-PCR. EWS-ERG fusion transcript was not detected in any of the cases. EWS gene translocation was found in 9 of 10 cases by FISH.

CONCLUSIONSInterphase FISH and RT-PCR can be reliably applied to paraffin-embedded tissues for molecular diagnosis of ES/PNET. Between the two approaches, interphase FISH provides a more sensitive and stable result.
