Objective To investigate the efficacy and cardiovascular disease of Danhong injection in the treatment after cardiac interventional therapy.Methods A total of 64 cases with cardiac intervention from September 2013 to July 2015 in our hospital were selected and divided into control group and experiment group with 32 cases in each group.Patients in the control group were given aspirin 100mg orally,and patients in the experiment group revieved Danhong injection 20mL intravenous drip qd,one times a day for 14 days.Two groups of patients underwent cardiac intervention.After the operaiton,the control group was given aspirin enteric-coated tablets 100mg orally,clopidogrel 75mg orally,and patients in the experiment group revieved Danhong injection 20mL intravenous drip qd,seven days for a course and the patients treated for three courses.The clinical efficacy,C-reactive protein(CRP),cardiac troponin T(TnT),P-selectin(Ps),PSGL-1,cardiovascular events(cardiovascular events),and adverse events were compared.Results After treatment,the clinical efficacy in experiment group was 93.75％,which significant higher than that in control group 71.88％,the difference was statistically significant(P<0.05).The rate of cardiovascular events in experiment group was 21.88％,which significant lower than that in control group 40.63％,the difference was statistically significant(P<0.05).The serum C-reactive protein,troponin T,Ps and PSGL-1 were significantly decreased in the two groups,and the experimental group was significantly smaller than the control group,the difference was statistically significant(P<0.05).The incidence of adverse reactions was 15.63％in the control group and 9.38％in the experimental group,the difference was not statistically significant.Conclusion Danhong injection treatment of elderly patients with cardiac intervention after the clinical effect is significant,high security,the incidence of cardiovascular events is low.

AIM: To explore the change of delayed rectifier potassium channel (K_V) activity in alveolar macrophages (AM) in chronic obstructive pulmonary disease (COPD) rats. METHODS: COPD model was established by exposure of the animals to cigarette smoke. With whole-cell voltage- or current-clamp techniques, K_V activity, membrane capacitance and resting membrane potential (Em) in AM from COPD model and control rats were compared. RESULTS: (1) Significant increases in total mononuclear cells and AM in bronchoal aveolar lavage fluid (BALF) were found in COPD group compared with in control group. (2) The AM K_V current altitude in COPD group [(520.5?38.7)pA, (+50) mV, n=30] was significantly lower than that in control group [(713.6?44.4)pA, (+50) mV, n=30, P0.05), but had more positive Em (P

AIM: To observe the changes of iNOS and eNOS in lung tissue and NO in bronchoalveolar lavage fluid (BALF) in smoking rats. METHODS: 80 Wistar rats were divided into control, smoking group, L-NIL group and L-NAME group (rats were exposed to smoke and injected (i.p.) with selective iNOS inhibitor L-NIL or NOS inhibitor L-NAME). iNOS and eNOS protein levels in whole lung were detected by immunohistochemical staining, and NOS mRNA was quantified using RT-PCR. In addition, NO - 2/NO - 3 was determined using Griess assay. RESULTS: The expression of iNOS mRNA and protein in smoking rats increased, the expression of eNOS mRNA and eNOS protein decreased, and the total cell count and the level of NO - 2/NO - 3in BALF increased( P

It is key for research institutions to ensure the standardized supervision of the progression and fund use of research projects.Peking University People's Hospital designed and applied a whole-process management mode of projects based on information system,which oversaw the conduct and funds management of projects.The application of this mode has significantly promoted the management level of scientific research projects.

Objective To investigate the difference of apparent diffusion coefficients (ADCs) changes in three major salivary glands after gustatory stimulation using two different stimuli. Methods Thirty healthy volunteers were examined with a 1.5 T MR unit. A diffusion-weighted MR imaging (MR DWI) sequence was performed once at rest and continuously repeated 13 times after gustatory stimulation using a commercially available lemon juice and vitamin C tablets in the same volunteer by using self-controlled method. The subsequence of two stimuli was random. In addition, the salivary flow rates at rest and after stimulation were measured. Characteristics and differences in ADCs curves of three salivary glands before and after stimulation between two stimuli were analyzed. Comparison of maximum ADCs, maximum ADCs increase rates (IRs) and times to maximum ADCs(Tmax) between two stimuli was performed by using independent-samples t test. Correlation analysis between rest salivary flow rates and rest ADCs, the maximum salivary flow rates and ADCs after stimulation, the maximum salivary flow IRs and ADC IRs after stimulation were performed by using Pearson correlation test. Results In lemon juice stimulation group, the mean ADCs mostly showed a steady increase to peak values during the first DW MRI scan after stimulation in all glands, followed by a gradually decrease fluctuating slightly around the baseline values. In vitamin C stimulation group, the mean ADCs were significantly increased in all glands during the first DW MRI scan after stimulation, followed by a gradual upward trend till peak values. In lemon juice stimulation group, the mean Tmax of submandibular and sublingual glands[(184±122)s, (345±232)s, respectively] were significantly earlier than those[(454 ± 301)s, (528 ± 297)s, respectively] in vitamin C stimulation group (t=-3.517 and-2.548 respectively, P<0.01 for all). The mean maximum ADCs of three glands in lemon juice stimulation group[(1.05 ± 0.12) × 10-3 mm2/s, (1.22 ± 0.10) × 10-3 mm2/s and (1.26 ± 0.21) × 10-3 mm2/s, respectively] were all lower than those in vitamin C stimulation group[(1.13±0.13) ×10-3 mm2/s, (1.32±0.25) × 10-3 mm2/s and (1.57 ± 0.36) × 10-3 mm2/s, respectively], and the differences in parotid and sublingual glands between two groups were significant(t=-2.894 and-3.681 respectively, P<0.01 for all). The mean maximum ADC IRs of three glands in lemon juice stimulation group[(11.35±4.07)%, (8.81±5.40)%, (34.08±21.66)%, respectively] were significantly lower than those[(17.80 ± 12.72)%, (18.16 ± 18.93)%, (67.49 ± 46.04)% , respectively] in vitamin C stimulation group (t=-2.252,-2.330 and-3.432 respectively, P<0.05 for all) . In two groups, the mean maximum ADC IRs of parotid and submandibular gland were all significantly lower than sublingual gland (t=-5.994 and-6.443 respectively, P<0.01 for all). No correlation was observed between ADCs and salivary flow rates, ADC IRs and salivary flow rate IRs in two groups (P>0.05). Conclusion MR DWI with transient stimulation using lemon juice is more stable for evaluating the physiologic changes of salivary glands in vivo.
