The aim of this experiment was to study the effects of different feeding modes on growth performance,blood biochemical indexes and intestinal flora of lactating Holstein male calves.Twenty-four newborn Holstein male calves with body mass of(40.00±1.01)kg and similar day old were selected and randomly divided into four groups of six calves each.The subgroups were low-milk group(LM),high-milk group(HM),high-milk milk replacer feeding group(HMR),and low-milk switching to high-milk milk replacer feeding group(CMR).The results showed that:At 45 d,the body mass of calves in the HM group was significantly higher than that of calves in the other groups(P＜0.05),and at 60 d,the body mass of calves in the HM group was significantly higher than that of calves in the LM &.CMR groups(P＜0.05).At 90 d,the body mass of calves in the LM group was significantly higher than that of calves in the HM group.Throughout the ex-perimental period,the average daily weight gain and average pellet feed intake of calves in the LM group were significantly higher than that of calves in the HM group(P＜0.05).The calf globulin level in the HMR group was significantly higher than that in the LM and HM groups(P＜0.05);the plasma immunoglobulin A level of calves in the HM group was significantly lower than that of calves in the LM and HMR groups(P＜0.05);and the plasma immunoglobulin M level of calves in the HM group was significantly higher than that of calves in the LM and CMR groups(P＜0.05),and HMR group was also significantly higher than that of LM group(P＜0.05);plasma glutathione peroxidase level of calves in HMR group was significantly higher than that of LM group(P＜0.05);plasma malondialdehyde level of calves in LM group was significantly higher than that of calves in HMR and HM groups(P＜0.05),and CMR group was also significantly higher than that of HM group(P＜0.05).Relative abundance of Thermodesulfovibrio was higher in the HM group(P＜0.05),relative abundance of Bacteroidetes in the LM group was significantly higher than that in the HMR and HM groups(P＜0.05),relative abundance of Blautia in the HM group(P＜0.05),and relative abundance of Corynebacterium in the CMR group was significantly higher than that in the LM and HM groups(P＜0.05).In summary,calves in the LM group had better weaning weights and pellet feed intake;calves in the CMR group could compensate for growth by supplemental feeding of milk replacer to obtain more optimal weaning weights and pel-let feed intake;the HMR group proved that milk-free feeding could ensure stable growth of calves;and calves in the HM group had a better pre-lactation growth performance,lower levels of oxida-tive stress,and a healthier fecal flora.

Objective:To observe the effects of alprostadil at different doses on C-reactive protein (CRP), tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6) in patients with angina pectoris.Methods:From August 2017 to April 2018, 120 patients with angina pectoris admitted to China Coast Guard Hospital of the People's Armed Police Force were selected and divided into control group (60 cases) and observation group (60 cases) by random number table method.Both two groups received routine anti-angina treatment, while the control group received 10 μg alprostadil, the observation group received 20 μg alprostadil for 2 weeks.The changes of CRP, TNF-α, IL-6 and hemorheological indicators before and after treatment were compared between the two groups.Results:Before treatment, there were no statistically significant differences in the CRP, TNF-α and IL-6 between the two groups (all P>0.05). After treatment, the CRP, TNF-α and IL-6 levels in the observation group were (4.63±0.62)mg/L, (0.46±0.08)μg/L, (46.59±4.72)ng/L, respectively, which were significantly lower than those in the control group [(6.18±0.74)mg/L, (1.19±0.28)μg/L, (58.62±5.07)ng/L]( t=12.437, 19.418, 13.452, all P<0.05). The high shear viscosity, low shear viscosity, plasma viscosity and platelet aggregation rates in the observation group were (4.27±0.46)mPa/s, (8.07±0.18)mPa/s, (1.03±0.25)mPa/s, (37.42±1.05)%, respectively, which were lower than those in the control group [(5.14±0.588)mPa/s, (10.43±0.42)mPa/s, (2.01±0.46)mPa/s, (40.19±1.86)%] ( t=9.103, 40.006, 14.499, 10.046, all P<0.05). Conclusion:The conventional dose of alprostadil (20 μg) is effective in the treatment of angina pectoris.It can improve CRP, TNF-α, IL-6 and hemorheological parameters of patients.

Objective:To observe the efficacy of meglumine adenosine cyclophosphate (MAC) in the adjuvant treatment of chronic congestive heart failure(CHF) in the elderly, and its effects on cystatin C(Cys-C) and plasma B-type natriuretic peptide(BNP).Methods:From August 2017 to August 2018, 110 elderly patients with chronic CHF admitted to Zhejiang Provincial Armed Police Corps Hospital were selected and randomly divided into control group(55 cases) and observation group(55 cases) by random number table method.The control group was treated with routine treatment, while the observation group was treated with MAC on the basis of routine treatment.Both two groups were treated for 2 weeks.The clinical efficacy, left ventricular ejection fraction (LVEF), cardiac output, Cys-C and plasma BNP were compared between the two groups.Results:The total improvement rate of the observation group was 94.55%(52/55), which was higher than 78.18%(43/55) of the control group, the difference was statistically significant(χ 2=6.253, P<0.05). Before treatment, there were no statistically significant differences in LVEF, cardiac output, BNP and Cys-C between the two groups(all P>0.05). After treatment, the LVEF[(44.16±6.82)%], cardiac output[(8.07±1.45)L/min] of the observation group were significantly higher than those of the control group[(40.71±5.38)%, (6.44±1.37)L/min], and BNP[(1.65±0.24)mg/L], Cys-C[(552.79±10.46)mg/L] of the observation group were significantly lower than those of the control group[(2.31±0.48)mg/L, (681.73±12.71)mg/L], the differences were statistically significant( t=2.945, 6.060, 9.121, 0.551, all P<0.05). Conclusion:MAC has significant effect in the treatment of elderly patients with chronic CHF.It can improve the cardiac function of patients and reduce the plasma concentrations of Cys-C and BNP.

Objective To explore the prognostic value for cardiovascular events of elevated NT-proBNP in coronary heart disease(CHD) patients with metabolic syndrome(MS).Methods The level of NT-proBNP was measured in 165 CHD patients with MS diagnosed by coronary angiography.After 2 years follow-up,we recorded the corresponding cardiovascular events in those patients.Results The NT-proBNP level was much higher in ACS group than that in SCHD group( P ＜ 0.01 ).There were totally 45 events after 2 years.After adjustment of traditional risk factors including hypertension,diabetes,smoking history and high sensitivity C reactive protein( hs-CRP),Cox proportional hazard analysis indicated that high NT-proBNP level( ＞ 111.58ng/L)was an independent risk factor for future events (relative risk 2.67,P ＜0.01 ).Conclusion Elevated NT-proBNP level might be one of the independent risk factor for cardiovascular events in CHD patiens with MS.
