OBJECTIVETo establish discriminant functions of diarrhea-predominant irritable bowel syndrome (IBS-D) by studying it from quantitative diagnosis angle, hoping to reduce interference of subjective factors in diagnosing and differentially diagnosing Chinese medical syndromes of IBS-D.

METHODSA Chinese medical clinical epidemiological survey was carried out in 439 IBS-D patients using Clinical Information Collection Table of IBS. Initial syndromes were obtained by cluster analysis. They were analyzed using step-by-step discrimination by taking information of four Chinese medical diagnostic methods and serum brain-gut peptides (BGP) as variables.

RESULTSClustering results were Gan stagnation Pi deficiency syndrome (GSPDS), Pi-Wei weakness syndrome (PWWS), Gan stagnation qi stasis syndrome (GSQSS), Pi-Shen yang deficiency syndrome (PSYDS), Pi-Wei damp-heat syndrome (PWDHS), cold-damp disturbing Pi syndrome (CDDPS). Of them, GSPDS was mostly often seen with effective percentage of 34. 2%, while CDDPS was the least often seen with effective percentage of 5.5%. A total of 5 discriminant functions for GSPDS, PWWS, GSQSS, PSYDS, and PWDHS were obtained by step-by-step dis- crimination method. The retrospective misjudgment rate was 4.1% (16/390), while the cross-validation misjudgment rate was 15.4% (60/390).

CONCLUSIONThe establishment of discriminant functions is of value in objectively diagnosing and differentially diagnosing Chinese medical syndromes of IBS-D.

Mitogen-activated protein kinases (MAPKs) signal is one of the important ways in eukaryotic cell,which adjusts and controls the structure and function of the cell. MAPKs in eukaryotes include p38, ERK, JNK and ERK5, etc. With the deepening research,we found that the activation of p38, ERK, JNK signal pathways were closely related with osteoarthritis (OA) cartilage injury. MAPKs are the key signaling systems involved in the production of matrix metalloproteinases and the regulation of cartilage cell proliferation, apoptosis and differentiation. Expecially the matrix metalloproteinases can accelerate the degradation of articular cartilage. So it has been the new spot in pathogenesis of osteoarthritis study.

At present, the English translation of TCM terms of pulse picture are various, which would bring confusion to the study and research on TCM diagnostics. In this paper, four principles for the translation are suggested by the authors: to distinguish the nomenclature of term with its connotative explanation, to translate with commonly used words in general, to create new word with common affix and to differentiate the terms similar in meaning. The authors tried to make choice the best translation for each kind pulse picture, and explained the reasons for selection.

Background Eyes with filamentary keratitis present with serious clinical symptoms.This disease is easy to relapse and the treatment is tricky.At present,its pathogenesis is still unclear,and few works were done on filamentous composition.Objective This study was to analyze the composition of corneal filament by imageological and histopathological method,and discuss the formation mechanism of filamentary keratitis.Methods Eighty-eight eyes of 82 cases who suffered from filamentary keratitis were collected in Shandong Eye Hospital between January 2008 and January 2011.The etiologies of the patients were classified and the clinical data were recorded.Firstly,the corneal filiform strip was detected by laser scanning confocal microscopy (LSCM),and the corneal structure was examined by high-definition optical coherence tomography (HD-OCT).Then the composition of filamentary strip was analyzed by Giemsa and Masson trichrome staining of stretched preparation of filiform strip.Results Etiological study showed that filamentary keratitis occurred after penetrating keratoplasty in 40 eyes,after cataract surgery and photorefractive keratectomy (PRK) in 18 eyes,dry eye and neural dystrophic corneal disease in 14 eyes,acute conjunctivitis in 10 eyes.HD-OCT revealed that filament lesion developed to Bowman layer.Filament was composed of epithelial cells,inflammatory cells,mucus and the high reflective strip core with spiral arrangement under the LSCM,and epithelial cells,inflammatory cells and fibrous tissue were seen in the strip core.Giemsa staining exhibited that filament contained corneal epithelial cells,inflammatory cells,mucus and dark blued strip core with helical arrangement.Masson trichrome discovered that the strip core was red fibrous tissue surrounding by blue mucus.Conclusions Epithelial cells,inflammatory cells,mucus and the high reflective strip core with spiral arrangement are the main elements of filament in filamentary keratitis.The lesion can reach Bowman layer.The results contribute to reveal the formation mechanism of corneal filament and assist treatment.

0.05).Expressions of IL-2 in tears significantly decreased 1 d,1 week and 1 month after LASIK(P0.05).Compared with the expression of NGF in tears before operation,those of 1 d,1 week,1 month and 3 months after LASIK were significantly increased(P

Objective To investigate the effect of intra-articular carboxymethylated ehitosan(CM- CTS)injection on inducible nitric oxide synthase(iNOS)expression in cartilage at the early stage of os- teoarthfitis(OA).Methods Thirty-two white rabbits were underwent unilateral anterior cruciate ligament transection(ACLT)and were randomly divided into 4 groups 5 weeks after transection.Rabbits of group A re- ceived 0.3 ml of 2% high molecular weight CMCTS(H-CMCTS)once every two weeks.Rabbits in group B were treated using 2% low molecular weight(L-CMCTS)CMCTS at:the same intervals.Group C rabbits were injected intra-articularly with 0.3 ml of 1% sodium hyaluronate(Na-HA)once a week.Animals of group D were not injected.At sacrifice,11 weeks following surgery,the expression of iNOS in cartilages was analyzed by immunohistochemistry and reverse transcription-polymerase chain reaction(RT-PCR)methods.Results Both immunohistochemistry and RT-PCR showed that the level of iNOS expression of cartilage in CMCTS in- jection groups was lower than that in Na-HA injection group and the untreated group.There was no significant difference in iNOS expression between the two different molecular weight CMCTS injection groups. No signifi- cant difference of iNOS expression in cartilage was found between Na-HA injection group and the untreated group.Conclusion CMCTS suppresses iNOS expression in cartilage during the early stage of OA.Na-HA treatment has no effect on iNOS expression in cartilage.

This study was aimed to explore the effect of bone marrow-derived mesenchymal stem cells (MSC) on proliferation and activity of natural killer (NK) and NK-T cells. MSC was co-cultured with peripheral mononuclear cells from healthy donors in presence of IL-2, phytohemagglutinin (PHA) and mouse anti-human CD3 McAb (culture condition known to expand NK cells). The ratio of NK cells and NK-T cells was measured by flow cytometry and the effect of MSC on killing activity of NK cells against K562 cells was detected by MTT method after co-cultured with different densities of MSC. The results showed that MSC inhibited the production of NK cells in a dose-dependent manner generally. At the densities of 0, 1 × 10(5) and 5 × 10(5)/ml, the ratios of NK cells in the co-culture conditions were (16.9 ± 4.6), (14.0 ± 8.6) and (6.4 ± 4.6), respectively (P < 0.05). However, MSC could promote the formation of NK cells at lower MSC density (1 × 10(4)/ml), the ratio of NK cells reached to (20.9 ± 7.1), which was higher than that of culture condition without MSC (P < 0.05). The different densities of MSC in the co-culture conditions had no much influence on the ratio of NK-T cells (P > 0.05). MTT assay showed that the killing activity of suspended cells in co-culture system against K562 cells was parallel with the ratio of NK cells. Different densities of MSC regulated bidirectionally killing activity of NK to K562 cells by regulating bidirectionally ratio of NK cells. It is concluded that the MSC can promote the formation of NK cells and enhance its activity against tumor cells in the lower doses, while suppress the formation of NK cells and attenuate its tumor-killing effect in higher dose condition.

OBJECTIVETo explore the clinical efficacy of Gengxueting (GXT) in treating hysteromyoma and its effects on estrogen receptor (ER) and progesterone receptor (PR).

METHODSSixty-four hysteromyoma patients with surgical indication were equally assigned to the treated group and the control group. Patients in the treated group were treated with GXT one capsule every day for 90 consecutive days before surgical operation, while those in the control group were treated with surgery alone. Serum levels of reproductive hormones were determined in the follicular phase before medication and one day before operation by RIA, and colored Doppler ultrasound examination was conducted for measuring the size of uterus and myoma. Moreover the protein expressions of ER and PR in tumor and uterine muscular tissues were detected by immunohistochemistry assay with streptomycin avidin-biotin peroxidase complex method.

RESULTSIn the treated group after medication, the serum level of estradiol was (167.0 +/- 85.9) pmol/L, progesterone (1.9 +/- 1.0) nmol/L, follicle-stimulating hormone (10.4 +/- 2.1) IU/L, and luteinizing (12.0 +/- 9. 8) IU/L, all reached the levels of early follicular phase, with the maximal size of myoma significantly decreased from (380.4 +/- 21.0) cm3 to (162.3 +/- 14. 8) cm3 (P < 0.01); and the ER and PR expressions in tumor tissue were significantly lower than those in the control group respectively (P < 0.01).

CONCLUSIONExpressions of ER and PR in hysteromyoma tissue could be significantly reduced by medication of GXT, which leads to significant shrinkage of tumor size and improvement of clinical symptoms.
