The problem based teaching (PBT) has been the main approach to the training in the universities o the world. Combined with the team oriented learning method, PBT will become the method available to the education in medical universities. In the paper, based on the common questions in teaching Jingluo Shuxue Xue (Science of Meridian and Acupoint), the concepts and characters of PBT and the team oriented learning method were analyzed. The implementation steps of PBT were set up in reference to the team oriented learning method. By quoting the original text in Beiji Qianjin Yaofang (Essential recipes for emergent use worth a thousand gold), the case analysis on "the thirteen devil points" was established with PBT.

AIM:To explore the ability of different group B streptococci ( GBS) strains on inducing platelet activation.METHODS:Six strains of GBS, separated from the septic patients with thrombocytopenia, were used as the inducers.Light transmission aggregometry was used to measure platelet aggregation.Scanning electron microscopy ( SEM) was performed to investigate the interaction of platelets with bacteria.The expression of platelet CD62P, Toll-like receptor 2 ( TLR2) and TLR4 was determined by flow cytometry and Western blotting.Furthermore, the activity of platelet TLR2 (or TLR4) was blocked by anti-TLR2 (or anti-TLR4) monoclonal antibody, and the platelet aggregation induced by GBS was detected.RESULTS:Only 3 of 6 GBS strains isolated from the septic patients induced platelet aggregation and up-regulated the expression of CD62P and TLR2 in the platelets (P<0.05), but not TLR4.Incubation with anti-TLR2 anti-body, but not anti-TLR4 antibody, significantly blocked platelet aggregation induced by GBS.CONCLUSION:Some GBS strains from the patients are able to trigger platelet activation in vitro, and platelet TLR2 may play an important role in the interaction between GBS and platelets.

Objective: To study the relationship between the expressions of Bel -2, Ki -67, C -myc and prognosis in patients given chemotherapy for malignant lymphoma (ML). Methods: The expressions of Bel-2, Ki-67 and C-myc were measured by immunohistochemistry (IHC) in paraffin-embedded samples of 65 ML cases who received chemotherapy. The survival analysis was done by the Kaplan -Meier method and Log -rank test. Results: For patients with non -Hodgkin lymphoma (NHL) who received chemotherapy, the 3-year disease free survival (DFS) was 22.22% in Bcl-2(+) group compared with that of 55.56% in Bcl-2 (-) group. The difference of DFS was significant between the two groups. Meanwhile, for ML patients, the 3-year DFS was 37.50% in Ki-67(+) group, and 61.54% in Ki-67(-) group respectively(P < 0.05). Conclusion: The expressions of Bcl-2 and Ki-67 were closely related with relapse after chemotherapy in patients with ML. They were useful molecular makers for predicting the prognosis in patients with ML after chemotherapy.

Their structures were determined on the basis of spectral analysis. Five compounds were isolated and identified as Withaphysalin P(I), 14, 18-di-O-acetylwithaphysalin C(II), Withaphysalin Q(III), Withaphysalin 1(IV)and Withaphysalin 2(V). Compounds IV and V are new compounds, orderly named as Withaphysalin T and Withaphysalin U.

Objective:To observe the changes in bone mineral density and microstructure parameters in sclerostin (SOST) gene knockout (SOST -/-) mice after ovariectomy. Methods:Twelve 4-week-old SOST knockout mice were randomly divided into two groups ( n=6): ovariectomized group (SOV), sham operated group (SSO). Twelve wild-type mice were randomly divided into two groups ( n=6): wild-type ovariectomized group (WTO), wild-type sham operated group (WTS). Twelve weeks later, mice were sacrificed and one lumbar vertebra of each mouse was selected for micro-CT analysis. The bone mineral density, trabecular volume fraction, trabecular number and trabecular thickness were observed and compared in the 4 groups. Results:There was no difference in bone mineral density, trabecular volume fraction, trabecular number and trabecular thickness between SOV and SSO groups. Bone mineral density, trabecular volume fraction, trabecular number and trabecular thickness in SOV and SSO groups were significantly higher than those in WTO and WTS groups ( P<0.001). Bone mineral density, trabecular volume fraction and trabecular number in WTO group were significantly lower than those in WTS group ( P=0.017, 0.039, 0.021, respectively). There was no difference in trabecular thickness between WTO and WTS groups. Conclusions:Sclerostin knockout mice showed high bone mass, and ovariectomy did not lead to bone loss and bone microstructure degeneration, which indicates that slerostin is a potential therapeutic target for postmenopausal osteoporosis.

Teaching rounds is an important part of clinical teaching. It bright the theory guide to clinical practice. The classical Chinese medicine theory plays an essential role in teaching and clinical practice. During the CBL (case-based learning) teaching rounds of acupuncture and moxibustion, by selecting typical cases, in combination with directional problem settings, the classical Chinese medicine theory is run through the whole process to motivate students' initiative, improve teaching quality and promote inheritance and development of TCM.

OBJECTIVETo understand the distribution of diarrheagenic Escherichia (E.) coli in population in Shanghai and discuss the practice model of cooperation in enteric infectious disease prevention and control between public health institution and hospital.

METHODSSentinel hospitals were assigned, standard detection and identification of diarrheagenic E. coli were conducted, incidence curve of diarrheagenic E. coli infection was drawn and epidemiologic survey and laboratory detection were conducted for suspect diarrheagenic E. coli infection outbreaks.

RESULTSA total of 7 204 stool specimens were collected from diarrhea patients in 4 hospitals during 2012-2013, in which 712 (9.9% ) were diarrheagenic E. coli positive, including 351 enteropathogenic E. coli (EPEC) strains, 292 enterotoxigenic E. coli (ETEC) strains, 32 enteroinvasive E. coli(EIEC) strains and 6 Shiga toxin-producing E. coli (STEC/EHEC) strains, as well as 31 mixed strains. EPEC infection mainly occurred in children aged 1-5 years; and all of these infections were caused by aEPEC. The incidence peak of ETEC infection was during August, the positive rate was >20%. The ETEC infection mainly occurred in infants aged 1-28 days in 2012 and in people aged 20-60 years in 2013 (P<0.05). ST was the major type (59.6%), followed by LT (27.8%) and ST/LT (12.6%). EIEC infection increased in children obviously in 2013 (P<0.01). No EHEC O157:H7 case was detected, but two EHEC O26:H11 (eae-hlyA-stx1a) cases in children were reported for the first time in Shanghai. The survey result indicated that the multidrug-resistant ETEC (STh-CS21-CFA/I-ClyA-EatA-ST2332-SHNL0005) strain causing outbreak in 15 newborns in Shanghai in 2012 was in the same clone as the strain detected in Zigong in Sichuan province.

CONCLUSIONSignificant change has occurred in diarrheagenic E. coli distribution in Shanghai in recent years, ETEC has potential risk to cause outbreak of hospital acquired infection in neonates and food borne infection. The active surveillance on ETEC and other enteric pathogens by both public health institutions and hospitals need to be improved.

Metabolic reprogramming, a newly recognized trait of tumor biology, is an intensively studied prospect for oncology medicines. For numerous tumors and cancer cell subpopulations, oxidative phosphorylation (OXPHOS) is essential for their biosynthetic and bioenergetic functions. Cancer cells with mutations in isocitrate dehydrogenase 1 (IDH1) exhibit differentiation arrest, epigenetic and transcriptional reprogramming, and sensitivity to mitochondrial OXPHOS inhibitors. In this study, we report that berberine, which is widely used in China to treat intestinal infections, acted solely at the mitochondrial electron transport chain (ETC) complex I, and that its association with IDH1 mutant inhibitor (IDH1^mi) AG-120 decreased mitochondrial activity and enhanced antileukemic effect in vitro andin vivo. Our study gives a scientific rationale for the therapy of IDH1 mutant acute myeloid leukemia (AML) patients using combinatory mitochondrial targeted medicines, particularly those who are resistant to or relapsing from IDH1^mi.
