OBJECTIVETo observe the effects of Xinshuai Mistura (XM) on plasma angiotensin II (Ang II), atrial natriuretic peptide (ANP) and N terminal pro- brain natriuretic peptide (Nt-proBNP) in patients with heart failure (HF).

METHODSFifty-nine patients with HF (NYHA class II-IV) were randomly divided into two groups, the treated group treated with XM and the control group with Wuling Pulvis (WP), both on the base of captopril treatment. The treatment course was two weeks. Plasma levels of Ang II , ANP and Nt-proBNP were observed.

RESULTSThe plasma levels of Ang I, ANP and Nt-proBNP showed an ascending tendency along with the increasing in severity of HF(P < 0.01), and significantly decreased after treatment in the treated group (P < 0.01), but with no remarkable difference as compared with those in the control group (P > 0.05).

CONCLUSIONXM had definite therapeutic effects on excessive neuroendocrine activation in HF patients.

AIM: To study the neuroprotective roles of neuroglobin (NGB) over-expression in the SH-SY5Y cells transfected with pAPPswe.METHODS:The plasmid pEGFP-NGB was successfully constructed and transfected into the SH-SY5Y cells, which were pretreated with pAPPswe.MTT assay was applied to detect the effect of NGB over-expres-sion on the cell survival rates.JC-1 staining was used to detect the level of mitochondrial transmembrane potential.The cell apoptosis was analyzed by flow cytometry.The effects of NGB over-expression on the protein level of p-Akt, Akt and caspase-3/9 were determined by Western blotting.The generation of Aβ42 in the cells was measured by ELISA.RE-SULTS:The cell survival rate was remarkably increased after transfection with NGB compared with control group and emp-ty plasmid group (P<0.05).The over-expression of NGB significantly inhibited the decrease in mitochondrial membrane potential induced by pAPPswe.The over-expression of NGB inhibited the apoptosis of the cells.Furthermore, over-expres-sion of NGB not only inhibited the expression of caspase-3 and caspase-9, but also induced the production of p-Akt, which was prevented by LY294002, an inhibitor of PI3K/Akt.The generation of Aβ42 was inhibited in the cells with the over-ex-pression of NGB.CONCLUSION: Over-expression of NGB significantly inhibits the SH-SY5Y cell injuries induced by pAPPswe and inhibits the expression of caspase-3/9, which is tightly related with cell apoptosis.Furthermore, the neuro-protective roles of NGB may be via activating PI3K/Akt signaling pathway.

AIM:To explore the effects of transforming growth factor-α( TGF-α) in the monoclonal formation , proliferation, migration and adhesiveness of human endothelial progenitor cells ( EPCs).METHODS: The isolated and cultured EPCs were treated with various concentrations of TGF-α(final concentrations of 1, 5, 10μg/L, respectively).At the same time, the PBS control and epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) group (10μg/L TGF-αplus 1∶1 000 EGFR-TKI) were set.The effects of TGF-αon monoclonal formation , proliferation, migration and adhesiveness of EPCs were determined by clone formation experiment , thiazolyl blue tetrazolium bromide (MTT), EdU, Transwell and adhesion assays , respectively.The expression of epithelial growth receptor (EGFR) and vascular endothelial growth factor ( VEGF) were measured by Western blotting .RESULTS:Different concentrations of TGF-αall significantly induced the monoclonal formation , proliferation, migration and adhesiveness of EPCs (P<0.01), which were inhibited by EGFR-TKI.The results of Western blotting showed that TGF-αalso induced the expression of EGFR and VEGF with a cer-tain concentration effect ( P<0.01) .CONCLUSION:By combining with EGFR induced the expression of VEGF , TGF-αsignificantly promotes the related cell function of monoclonal formation , proliferation, migration, adhesiveness in EPCs.

AIM: To evaluate the safety and efficacy of one transscleral sutured fixation intraocular lens implanted in the capsular treating traumatic lens dislocation.
METHODS: Twelve eyes with lens subluxation from 12 patients during Mar. 2013 to Mar. 2015 were reviewed. The stopping and chopping method combined with manual nuclear extraction was performed in extent of lens subluxation less than 1/2 quadrant and transscleral sutured fixation intraocular lens implanted in the capsular. Visual acuity, best - corrected visual acuity, intraocular pressure, corneal endothelial cell count and the position of IOL were observed and recorded.
RESULTS: All the surgeries were performed successfully. Patients were followed up for 6 - 12mo. During the follow-up period, the number of eyes for BCVA ≥0. 8, 0. 4 - 0. 6 and ≤0. 3 was 2, 7 and 3, respectively. It meant 66. 67% of the eyes showed BCVA in 0. 5-0. 6. Intraocular pressure and the position of all intraocular lens were normal. Effects of operation on corneal endothelial cells were slight. No complications took place in and after surgery.
CONCLUSION: Without implanting capsular tension ring ( CTR ) , we successfully use the intraocular lens ( IOL) single loop suture fixation in the capsular bag for the treatment of the patient with traumatic lens dislocation. It indicates that the pressure and place shift from the use of IOL avoided by this method without implantation of CTR. This method is safe and effective for the treatment of eyes with traumatic lens dislocation.

Objective To investigate the clinical features of Crohn's disease(CD)and ulcerative colitis(UC)according to the Montreal classification.nethods The clinical data of 110 cases of CD or UC were reviewed.The age at diagnosis.location and clinical behavior were assessed with the Montreal criteria.Results CD patients diagnosed at an age younger than 16 years were rare(3.6%),the majority of the CD patients was diagnosed at 17-40 years old(65.5%).Although ileocolon lesions were most common in the patients diagnosed at 17-40 years old(37.3%),yet ileum lesions were a little more than those of other parts of digestive tract in the patients diagnosed after 40 years old(14.5%),the difference was not significant(P=0.054).Stricture frequently occurred(50.4%),especially when the lesions were located at ileum or ileocolon.Perforation rarely happened(5.3%).There was no significant difference between different location groups for clinical behaviors(P=0.096).The incidence of stricture or perforation was almost same among different age groups(P=0.984).UC patients mostly presented with mild or moderate symptoms even in the group with extensive lesion.UC patients with severe symptoms were rare(6.8%).There was no significant difference in severity between the groups with different extent of lesion (P=0.056).Conclusions The majority of CD patients was diagnosed at 17-40 years old.Stricture is much more than perforation,penetrating,occurring mostly at ileum.UC patients mostly present mild or moderate symptoms,no matter how extensive the lesion is.The extent of the lesion detected with coloscopic examination is not correlated to the severity of clinical manifestations.

OBJECTIVETo investigate the effects of total saponins from Sanguisorba officinalis (DYS) on hematopoietic cell proliferation, differentiation and the expression level of IL-3R and c-kit.

METHODBaf3 and 32D cells were cultured with or without IL-3, then the cells were exposed to DYS in different concentrations of 5, 10, 20, 30 and 40 mg x L(-1) for 24, 48, 72 and 96 hours separately. After that, the cell proliferation and differentiation capacity were determinated by the methods of CCK8 and Giemsa staining separately. The effects of DYS on the expression level of IL-3 receptor in Baf3 cells and the expression level of c-kit in 32D cells were determinated using RT-PCR.

RESULTDYS promotes alone proliferation of Baf3 cells and 32D cells after 48 h. In contrast to control cells, 32D cells containing DYS without IL-3 form many large clusters. DYS also increases the proliferation when cultured with IL-3. High concentration of DYS induce alone the differentiation of 32D cells and increase alone the number of the polyploidy megakaryocyte. Moreover, DYS increases alone the expression level of IL-3R in Baf3 cells and the expression level of c-kit in 32D cells separately.

CONCLUSIONOur data shows DYS can promote alone proliferation and differentiation of megakaryocyte progenitor cells. The proliferative and differentiative effect of DYS on megakaryocyte progenitor cells is correlated to the up-regulation of IL-3 receptor and c-kit expression.

Raynaud Syndrome(RS) is a kind of paroxysmal digital ischemic disease whose typical symptom is characteristic tricolor change featuring pallor,cyanosis,and erythema induced by cold or emotion changing.The pathogenesis of RS is still not entirely clear,and there is no radical treatment.In recent years,endoscopic thoracic sympathectomy (ETS) for Raynaud Syndrome is gradually applied.ETS produces a high rate of initial relief,and has lower risk and technical difficulty compared with other surgical options,while its poor long-term outcome can't be ignored.There is currently a lack of a large number of clinical controlled trials between different operations,and there is still a need for further improved surgical procedures and accurate postoperative evaluation criteria.In this review,the recent advances of ETS is summarized.

In recent years, benefited from the progress of clinical studies of early diagnosis and early revascularization in acute myocardial infarction (AMI), the guidelines for Europe and the United States and the Chinese academic continue to be updated to guide our clinical practice. However, AMI still remains one of the major causes of death in the worldwide. Over the past 10 years, the incidence of AMI increased rapidly in China, and the mortality kept at a high level. There is still plenty of room to improve in the early diagnosis of cardiac troponin, revascularization strategy optimization of non-infarct-related vascular, optimized new antiplatelet therapy, development of regional synergies network and chest pain center. There is still a long way from the standardized treatment of AMI. It is very important to complete early diagnosis and optimum treatment of AMI.
