The value of assessing femoral vein to femoral artery ratio in the treatment of patients with heart failure / 中华心血管病杂志

Objective@#To investigate the relationship between ultrasound derived ratio of femoral vein to femoral artery diameter and hemodynamics in patients with heart failure.@*Methods@#This was a case-control study. A total of 61 patients with heart failure and 49 patients with non-heart failure hospitalized in the Department of Critical Care Medicine from September 2017 to September 2018 were included in this study. Doppler ultrasound was used to measure the femoral artery and vein diameter. After deep inhalation, the femoral vein diameter was measured again, and the ratio of femoral vein and artery diameter was calculated. The central venous pressure (CVP) and mean pulmonary wedge pressure (mPAWP) were also measured. Pearson correlation analysis was used to explore the correlation between the ratio of femoral vein diameter to femoral artery diameter and CVP and mPAWP, and linear regression equation was established.@*Results@#The overall CVP and mPAWP levels were significantly higher, and the femoral vein diameter after deep inhalation was bigger in heart failure patients than in non-heart failure patients(all P<0.001). The femoral vein diameter/femoral artery diameter ratio was positively correlated with CVP (r=0.76, P<0.001), and positively correlated with mPAWP (r=0.40, P<0.001) in heart failure group. The linear regression equation established by the femoral vein/femoral artery diameter ratio and CVP in the heart failure group showed that the inner diameter of the femoral vein/the inner diameter of the femoral artery ratio≥1.3 corresponded CVP≥15.518 cmH2O(1 cmH2O=0.098 kPa) in heart failure patients.@*Conclusions@#In patients with heart failure, the inner diameter of the femoral vein/femoral artery ratio is positively correlated with CVP and mPAWP. The ratio of inner diameter of the femoral vein/femoral artery can be used to assess the volumetric load of patients with heart failure and to guide the clinical treatment of heart failure patients.

Clinical analysis of minimally invasive surgery combined with medication in the treatment of ureteral calculi / 局解手术学杂志

Objective To analyze of the efficacy of minimally invasive surgery combined with medication in the treatment of ureteral calculi.Methods From June 2013 to June 2015,124 patients with ureteral calculi which confirmed by X-ray in our hospital were collected as subjects.According to the treatment method,they were divided into control group and observation group,patients in the control group were treated with simple medication,while the observation group were treated with minimally invasive surgery combined with drug therapy.The effects of treatment and the levels of MCP-1,TFF1 and HMGB1 in urine between two groups were compared.Results The stone expulsion rate and the net rate of the observation group was higher than those of the control group,the differences were significant(P<0.05).The stone expulsion time of observation group was shorter than that of the control group,the formation rate of the observation group was lower than that of the control group,the differences were significant(P<0.05).Adverse reactions occurred in 11 cases of the observation group,in 29 cases of the control group,the incidence of adverse reactions in the observation group was lower than that in the control group,the difference was significant(P<0.05).After the treatment,17 cases of adverse drug reactions occurred in the observation group,which was more than 5 cases of adverse drug reactions in the control group,the difference was significant(P<0.05).After treatment,the levels of MCP-1 and HMGB1 in urine of two groups were decreased compared with those before treatment,the level of TFF1 was increased,the differences were significant(P<0.05);while the levels of MCP-1 and HMGB1 of the observation group after treatment were lower than those of the control group,the level of TFF1 was higher than that of the control group,the difference was significant(P<0.05).The effective rate of the observation group was 88.71％,which higher than 69.35％ of the control group,the difference was significant(P<0.05).Conclusion On the basis of medication,combined with extracorporeal shock wave lithotripsy for ureteral calculi can not only improve the therapeutic effect,but also reduce the risk of adverse reactions.

Research on compatibility chemistry of acid-alkaline pair medicines in formulas of traditional Chinese medicine / 中国中药杂志

Compatibility chemistry of acid-alkaline pair medicines in formulas of traditional Chinese medicine (TCM) is an important research field which should merit to pay attention. The ideas and methods in prescription compatibility research on formulas containing alkaline-acid pair medicines were summarized from the aspect of chemical groups of alkaline and acid ingredients; the research results were introduced and analyzed; the research meaning was elaborated; and the expectation of the field was viewed.

OBSERVATIONS AND MEASUREMENTS OF THE CEREBELLAR ARTERIES / 解剖学报

Cerebellar arteries and their branches injected with red latex were observed on 50 adult human brains with the naked eye and stereomicroscope. The external and internal diameters of the arteries and the thickness of their walls were measured.According to the distribution, we named the middle inferior cerebellar artery as anterior inferior cerebellar artery, and the long stem type of the anterior inferior cerebellar artery as the posterior infericr cerebellar artery. So that, there are only three pairs of cerebellar arteries: the superior, the anterior inferior and the posterior inferior arteries. Each of the three arteries may be single-branched double-branched or wanting. So the number of the cerebellar arteries is inconstant. The origins of these arteries are variable and the majority of the abnormal sites of origin are situated adjacent to the normal site rostrally. The arterial distributions on both sides are mostly unsymmetrical. These arteries anastomose with each another. If the anterior inferior cerebellar artery is absent the other two arteries of the same side compensate for its loss. While the posterior inferior cerebellar artery is absent or thin it will be compensated for not only by the others of the same side but also by the branches from the corresponding artery of the opposite side. Concerning the diameter of these arteries, the superior cerebellar artery is the largest; the posterior inferior cerebellar artery comes next and the anterior inferior cerebellar artery is the smallest. The blood flow of the inferior surface of the cerebellum, supplied by the posterior inferior artery together with the anterior inferior artery is more abundant than that of the superior surface supplied only by the superior artery.Posterior inferior cerebellar arteries may be classified into two types:deep situated and superficial siluated types. The latter takes 36.8%. It can easily be found and safely operated when performing the operation of anastomosing the posterior inferior cerebellar artery with the occipital artery.
