Objective To evaluate the efficacy of tegaserod in treating overlapping symptoms of chronic constipation and dyspepsia or reflux.Methods Eighty eight patients with overlapping symptom were enrolled and randomly divided into:tegaserod group(TEG group,received tegaserod 6 mg bid), PPI group(esomeprazole 40 mg qd)and combined group(tegaserod 6 mg bid and esomeprazole 40 mg qd).Esomeprazole was taken 30 min-prior to the meals in the morning.Each group was treated for 4 weeks.Endpoints to evaluate the clinical efficacy including complete relief rates(CRRs)of epigastric symptoms,the total scores of gastrointestinal symptoms,gastric emptying and colonic transit time and gastric sensation.Results The total scores of gastrointestinal symptoms were all significantly decreased in three groups after four-week therapy,which were more decreased markedly in TEG group(7.23?3.13)and the combined group(5.13?2.26)than that in PPI group(13.58?2.02,P

Background Retinal angiomatous proliferation (RAP) is a subtype of neovascular age-related macular degeneration (AMD).There are currently very few studies on RAP.Objective This study was to explore the pathogenic mechanism of RAP in apolipoprotein E-deficient (ApoE-/-) mice with dyslipidemia.Methods Twenty-four 2-month-old SPF ApoE-/-mice were randomly divided into the high fat diet group and the normal diet group,and twelve 2-month-old C57BL/6 mice received the normal diet as controls.A diet with a higher content of fat was given for 4 consecutive months in the high fat diet group,and normal diet was given in the same way in the mice of the normal diet group.The mice were sacrificed at 6 months of age.The expression of vascular endothelial growth factor (VEGF) in the retinal pigment epithelial (RPE) cells,the expression of vascular endothelial growth factor receptor-2 (VEGFR-2) in the outer plexiform layer (OPL),microvascular density (MVD) and microvascular area (MVA) in the OPL were examined by immunohistochemistry and semi-quantitatively by histopathology with the Mias 2000 Imaging Analyzer System.The expression of VEGF protein in the retina was examined by Western blot.Results The MVD in the retinal OPL were (20.67±3.20) and (19.50± 1.87),respectively,in the ApoE-/-mice of the high fat diet group and the normal diet group,which were significantly higher than that (12.50±1.87) of the C57BL/6 normal diet group (all at P<0.01).MVA in the retinal OPL were (626.49± 120.99) μm2 and (514.06±88.83) μm2 in the ApoE-/-mice of the high fat diet group and the normal diet group,respectively,showing a significant increase in comparison with the (336.52±84.96) μm2 of the C57BL/6 normal diet group (P<0.01).The staining area of VEGF in RPE cells was (21 048±1849) μm2 in the ApoE-/-mice of the high fat diet group,showing a significant increase in comparison with the (17 116±2023) μm2 of the C57BL/6 normal diet group.However,no significant difference was found in the staining area of VEGF between the ApoE-/-mice with normal diet group and the C57BL/6 normal diet group ([17 854±2967] μm2 vs.[17 116±2023] μm2) (P>0.05).Significant elevation was also seen in the staining area of VEGFR-2 in the retinal OPL of the ApoE-/-mice of the high fat diet group (12 193±3806)μm2 and the ApoE-/-mice of the normal diet group (11 969± 3616)xm2 compared with C57BL/6 mice of the normal diet group (5387±2225)μm2(all at P<0.01).The relative expression values (VEGF/β-actin) of VEGF in the retinas were (1.51 ±0.32) and (1.17±0.39) in the ApoE-/-mice of the high fat diet group and the normal diet group,respectively,showing a significant increase in comparison with (0.28±0.14) of the C57BL/6 normal diet group (P<0.01).Conclusions The expression of VEGF and VEGFR-2 in the retinas increases in the ApoE-/-mouse,which leads to the enlargement of MVD and MVA in the retinal OPL and subsequent RAP occurrence.

Bronchiolitis is a common lower respiratory tract viral infection in infants.Incidence of bronchiolitis is greatly increasing in recent years,and seriously affecting the health of children.In order to better manage bronchiolitis,American Academy of Pediatrics (AAP) convened a new subcommittee to review and revise the 2006 bronchiolitis guideline.This evidence-based guideline amended to provide new evidence of diagnosis,treatment and prevention bronchiolitis for the clinician.

Neonatal pain is a common phenomenon. For a long time neonatal pain had not been focus on properly and managed appropriately. American Academy of Pediatrics Committee on Fetus and Newborn and Section on Anesthesiology and Pain Medicine published policy statement to emphasize the necessity of neonatal pain assessment,and summarize the neonatal operability pain assessment method,drug and non-drug control measures,also update prevention and management of procedural pain in the neonate in 2016. Until today the guideline for neonatal pain management has not yet been released in China. As the reference for clinicians in domestic,the content of policy statement will be reorganized and introduced.

AIM: To observe if there is a synergistical effect on induction of apoptosis when arsenic trioxide alone or combination with bortezomib in KM3 cells. METHODS: KM3 cells were treated with arsenic trioxide alone or combined with bortezomib, the numbers of viable cells were determined by trypan blue exclusion. Cell growth inhibition was examined by MTT method. The cells were simultaneously stained with annexin V-FITC and PI and apoptosis was determined by bivariate flow cytometry using a FACScan. Reverse trascriptional-PCR (RT-PCR) method was used to examine the change of p65 mRNA and Western blotting to measure the expression of protein p65, p-p65, caspase-3, -8, -9, and poly ADP-ribose polymerase (PARP). RESULTS: Arsenic trioxide inhibited the cell growth and induced apoptosis. The mechanism was responsible for the activation of caspase-mediated induction of apoptosis. A synergistic effect of combination with bortezomib on apoptosis was observed. CONCLUSION: Arsenic trioxide inhibits KM3 cell growth and induces apoptosis with a synergistical effect when cotreated with bortezomib.

ObjectiveTo investigate the corelation between fibrinogen in pleural effusion and pleural adhesion in tuberculosis exudative pleurisy.Methods234 cases of primary tuberculosis pleurisy were divided into 3 groups (A、B、C) according to their level of fibrinogen in pleural effusion from low to high. The incidence rates of pleural adhesion were assessed during the course of treatment and after treatment.ResultsThe incidence rate of pleural adhesion in the course of treatment were as those: group A 10.5%, group B 32.3%, group C 54.5%. After treatment, it was as those: group A 10.5%, group B 16.9%, group C 42.4%. Whenever, there was significant difference between group C and group A or B (P<0.05).ConclusionThe level of fibrinogen in pleural effusion may be associated with pleural adhesion, which hinder the recovery of patients.

This study examined the effect of cholic acid (CA) on cultured cardiac myocytes (CMs) from neonatal rats with an attempt to explore the possible mechanism of sudden fetal death in intrahepatic cholestasis of pregnancy (ICP). Inverted microscopy was performed to detect the impact of CA on the beating rates of rat CMs. MTT method was used to study the effect of CA on the viability of CMs. CMs cultured in vitro were incubated with 10 μmol/L Ca(2+)-sensitive fluorescence indicator fluo-3/AM. The fluorescence signals of free calcium induced by CA were measured under a laser scanning confocal microscope. The results showed that CA decreased the beating rates of the CMs in a dose-dependent manner. CA could suppress the activities of CMs in a time- and dose-dependent manner. CA increased the concentration of intracellular free calcium in a dose-dependent manner. Our study suggested that CA could inhibit the activity of CMs by causing calcium overload, thereby leading to the sudden fetal death in ICP.
