Wuyi is one of the Chinese medicine recorded in Shennong's Herbal Classic and many other herbal books during the long history period. Up to now, Wuyi is still an important medicine used for insecticidal and removing food retention. Recent researches indicated that Wuyi also had the function of anti-malaria and treating herpetic simplex keratitis. Therefore, Wuyi had notable value on clinic and development of new medicine. The herbalogical textual research on Wuyi was conducted through investigation of the literature of materia medica during the long historical period from Han Dynasty. It was demonstrated by this work that the original plants of Wuyi include Ulmus macrocarpa Hance and Hemiptelea davidii (Hance) Planch, in which, U. macrocarpa was the quality specie. U. pumila was the false specie which cause confusing. The medicine Wuyi was the processed product made from the nutlet of the plants through fermentation with other additive agents.

The Tongmai Yangxin pill (TMYX) has potential clinical effects on no-reflow (NR); however, the effective substances and mechanisms by which this occurs remain unclear. This study evaluates the cardioprotective effects and molecular mechanisms of TMYX against NR. We used a myocardial NR rat model (2 h after myocardial ischemia and 2 h after reperfusion) to confirm the effect and mechanism of action of TMYX in alleviating NR. In vitro studies in isolated coronary microvasculature of NR rats and in silico network pharmacology analyses were performed to reveal the underlying mechanisms of TMYX and determine the main components, targets, and pathways of TMYX, respectively. The experiment was approved by the Ethics Committee of Hunan University of Chinese Medicine (LLBH-202212160001). TMYX showed therapeutic effects on NR by improving cardiac structure and function, reducing NR, ischemic areas, and cardiomyocyte injury, and decreasing the content of cardiac troponin I (cTnI). Moreover, the mechanism of TMYX predicted by network pharmacology is related to the hypoxia inducible factor-1 (HIF-1), nuclear factor kappa-B (NF-κB), and tumor necrosis factor (TNF) signaling pathways. TMYX increased the expression of G protein-coupled estrogen receptor (GPER), phospho-extracellular signal-regulated kinase (p-ERK), and HIF-1α. In vitro, TMYX enhanced the diastolic function of coronary microvascular cells; however, this effect was inhibited by GPER inhibitor (G-15), eNOS inhibitor (L-NAME), and sGC inhibitor (ODQ). This study integrates pharmacology and experimental evaluation to reveal that TMYX activates HIF-1α/eNOS signaling pathway by upregulating GPER to relax coronary microvessels, thereby significantly alleviating NR.

Our previous results have demonstrated that insulin reduces myocardial ischemia/reperfusion (MI/R) injury and increases the postischemic myocardial functions via activating the cellular survival signaling, i.e., phosphatidylinositol 3-kinase (PI3-K)-Akt-endothelial nitric oxide synthase (eNOS)-nitric oxide (NO) cascade. However, it remains largely controversial whether c-Jun NH2-terminal kinase (JNK) is involved in the effects of insulin on MI/R injury. Therefore, the aims of the present study were to investigate the role of JNK, especially the cross-talk between JNK and previously expatiated Akt signaling, in the protective effect of insulin on I/R myocardium. Isolated hearts from adult Sprague-Dawley rats were subjected to 30 min of regional ischemia and followed by 2 or 4 h of reperfusion (n=6). The hearts were pretreated with PI3-K inhibitor LY294002, or phosphorylated-JNK inhibitor SP600125, respectively, then perfused retrogradely with insulin, and the mechanical functions of hearts, including the heart rate (HR), left ventricular developed pressure (LVDP) and instantaneous first derivation of left ventricular pressure (+/-LVdp/dt(max)) were measured. At the end of reperfusion, the infarct size (IS) and apoptotic index (AI) were examined. MI/R caused significant cardiac dysfunction and myocardial apoptosis (strong TUNEL-positive staining). Compared with the control group, insulin treatment in MI/R rats exerted protective effects as evidenced by reduced myocardial IS [(28.9 +/- 2.0)% vs (45.0 +/- 4.0) %, n=6, P<0.01], inhibited cardiomyocyte apoptosis [decreased AI: (16.0 +/- 0.7) % vs (27.6 +/- 1.3) %, n=6, P<0.01] and improved recovery of cardiac systolic/diastolic function (including LVDP and +/-LVdp/dt(max)) at the end of reperfusion. Moreover, insulin resulted in 1.7-fold and 1.5-fold increases in Akt and JNK phosphorylation in I/R myocardium, respectively (n=6, P<0.05). Inhibition of Akt activation with LY294002 abolished, and inhibition of JNK activation with SP600125 enhanced the cardioprotection by insulin, respectively. And the abolishment by LY294002 could be partly converted by SP600125 pretreatment. In addition, SP600125 also decreased the Akt phosphorylation (n=6, P<0.05). These results demonstrate that insulin simultaneously activates both Akt and JNK, and the latter further increases the phosphorylation of Akt which attenuates MI/R injury and improves heart function; this cross-talk between Akt and JNK in the insulin signaling is involved in insulin-induced cardioprotective effect.

BACKGROUND:The incidence rate of peripheral T cel lymphoma is high in Asia, and peripheral T cel lymphoma is aggressive with generaly poor prognosis. However, there is no standard treatment strategy. OBJECTIVE:To retrospectively analyze the therapeutic effect of autologous hematopoietic stem cel transplantation on peripheral T cel lymphoma as wel as relevant toxic and side effects. METHODS:A retrospective review was conducted in 35 patients with peripheral T cel lymphoma who underwent autologous hematopoietic stem cel transplantation from March 2003 to April 2014, including 22 cases of extranodal NK/T-cel lymphoma (nasal type), 1 case of angioimmunoblastic T-cel lymphoma, 8 cases of peripheral T cel lymphoma (non-specific), 3 cases of ALK-positive anaplastic large cel lymphoma, and 1 case of ALK-negative anaplastic large cel lymphoma. Al of 35 patients were classified pathologicaly according to WHO pathological type in 2001 and 2008, and received the high-dose chemotherapy with vincristine, cytarabine, etoposide, mitoxantrone, semustine, cyclophosphamide, and total body irradiation. RESULTS AND CONCLUSION: After a median folow-up of 54 (9-120) months, the probabilities of overal survival and disease-free survival after transplantation were 80% (n=28) and 71% (n=25), respectively. Eight cases (23%) relapsed after transplantation, seven of which died. It was safe with mild and moderate transplantation related side-effects on opportunistic infections, oral cavity mucosa and bladder responses and so on, and there were no severe, life-threatening late complications. Autologous hematopoietic stem cel transplantation may be an effective and safe treatment for peripheral T cel lymphoma, and there is a better benefit in peripheral T cel lymphoma patients with first complete remission.

Objective To assess the diagnostic value of various preoperative imaging examinations for the point of the lateral femoral circumflex artery perforators through the deep fascia,in order to provide reasonable evidence for the design of location and protocol of anterolateral thigh perforator flap.Mehtods From September,2013 to December,2013,23 patients (including 1 patient with bilateral anterolateral thigh perforator flap) preparing anterolateral flap surgery were randomly divided into 4 groups(every group was 6 side).The patients in different groups were using different imaging techniques respectively,such as handheld doppler (HHD),Color doppler sonography (CDS),MDCT angiography (MDCTA),CDS and MDCTA united image location technology.The flap sizes varied from 8 cm × 5 cm to 28 cm × 12 cm.Moreover the coincidence rate between preoperative and intraoperative location of the perforator vessel was evaluated.Results Ali flaps were survived after the operation.The donor site were primarily closed while partial skin grafting was performed in 8 cases.The appearance and functional resuhs were satisfactory with following up for 3 to 9 months.The rates of coincidence between the preoperative and intraoperative location of perforating branches were HHD 61.53％,CDS 87.50％,MDCTA 85.71％,CDS and MDCTA united image location technology 93.33％ respectively.The HHD group showed significant decrease compared with the other groups (x2 =7.92,P ＜ 0.01; x2 =6.15,P ＜ 0.05; x2 =12.54,P ＜ 0.01,respectively).The CDS group had no statistically difference with the MDCTA group (P ＞ 0.05).The united CDS and MDCTA group showed significant increase compared with the other groups (x2 =4.22,P ＜ 0.05; x2 =3.94,P ＜ 0.05).Conclusion CDS and MDCTA united image location technology are more accurate for perforator preoperative location in auterolateral thigh flap,and should be widely used.

Objective To investigate the curative effect of allogeneic hematopoietic stem cell transplantation (allo-HSCT) and the method of the pretreatment choice on myelodysplastic syndrome (MDS).Methods 13 cases who were undergoing allo-HSCT including 10 HLA-matched, 2 HLA partially matched,and one umbilical cord blood transplanted patients were enrolled in this study. The infusion number of MNC and CD+34 cells is 6.92 (2.65-21.33)×108/kg and 4.47 (1.49-10.22) ×106/kg, respectively. Of the 13 cases,5 adopted TBI, fludarabine(Flud), and cyclophosphamide(Cy) pretreatment, 3 chose BU/Cy pretreatment, and 3 chose TBI and Cy pretreatment, 2 chose Ara-C+BU+Cy+VM26 pretreatment. In order to prevent GVHD, 2cases of HLA partially matched were treated with ATG, cyclosporin A (CsA), MTX and MMF aftertransplantation, while the others were treated with CsA and MTX only. Results 9 out of 13 cases achieved hematopoietic reconstruction completely. 4 died of complications. Conclusion The allogeneic hematopoietic stem cell transplantation is an efficient regimen to cure MDS. The pretreatment should adopt the individuation.

AIM:To detect the activation of macrophage autophagy caused by lipopolysaccharide ( LPS) and the possible related signaling pathways .METHODS:The macrophage cell line RAW264.7 cultured in vitro was divided into 5 groups according to the culture environment , including normal culture group , starvation-activated sautophagy group , LPS group, LPS+PI3K inhibitor (hVps34) group and LPS+mTOR inhibitor (rapamycin) group.Fluorescent expression vector pcDNA3.1-GFP-LC3 constructed in previous work was transfected into the macrophages .The fluorescence microscopy was used to detect the formation of autophagosome .The mRNA expression of autophagy-associated genes Atg5, Atg7, LC3-II and Bnip3 in the macrophages was detected by qRT-PCR.The protein levels of LC3-II, p-Akt and p-mTOR were deter-mined by Western blotting , so as to evaluate the molecular pathways of autophagy in LPS-activated macrophages .RE-SULTS:The macrophages stably expressing GFP-LC3 were successfully established , which were used to observe the auto-phagy under fluorescence microscope .Compared with normal culture group , the autophagy in starvation group , LPS +hVps34 group and LPS+rapamycin group was significantly increased .The mRNA expression levels of Atg5, LC3-II and Bnip3 were significantly increased in starvation group , LPS+hVps34 group and LPS +rapamycin group , while in LPS group, those decreased slightly .The protein level of p-Akt in starvation group , LPS group and LPS+rapamycin group was significantly increased , while p-mTOR in starvation group , LPS+hVps34 group and LPS+rapamycin group significantly declined .LC3-II expression level in starvation group , LPS+hVps34 group and LPS+rapamycin group was higher than that in control group and LPS group .CONCLUSION: LPS regulates macrophage autophagy , and its possible pathway is the PI3K/Akt/mTOR pathway, but there are some other effective regulatory pathways .
