Objective To observe the effects of Huangqi injection associated with a combined treatment on changes of hemodynamics indexes and brain natriuretic peptide (BNP) after cardiopulmonary resuscitation (CPR) in rabbit models with cardiac arrest (CA) to elucidate the mechanism of such cardiac protective effects. Methods Twenty-four New Zealand rabbits were randomly divided into four groups(each,n=6). The CPR model in rabbits was reproduced by using extra-corporal electric shock method(put through 50 V alternating current to quiver on chest). The animals in operation control group were given anesthesia,all kinds of catheter inserted into the body and tracheotomy,but no induction of ventricular fibrillation. In the epinephrine group,epinephrine (30 μg/kg)was injected into the right jugular vein by a catheter during CPR. In the sub-hypothermia group, epinephrine(30μg/kg)was injected into the right jugular vein via a catheter and 0.9%sodium chloride under 4℃at a rate of 1.0 mL · kg-1 · min-1 was pumped into the ear marginal vein simultaneously with the chest external compressions during CPR and the cooling of body surface sustaining at the target temperature (32-34℃) for 4 hours until the end of the experiment. In the combined treatment group,Huangqi injection(4 g/kg)was injected into the right jugular vein on the basis of treatment of sub-hypothermia group. Hemodynamics indexes such as left ventricular end-diastolic pressure(LVEDP),the maximal rate of left ventricular pressure increase/decline(±dp/dt max),and the mean arterial pressure(MAP)were dynamically monitored at 15 minutes before inducing ventricular fibrillation and at the early stage of post resuscitation for 30,60,120,180,240 minutes,and in the mean time the concentration of BNP was dynamically monitored at 15 minutes before inducing ventricular fibrillation and at the early stage of post resuscitation for 30,180,240 minutes. Results Compared with those of the operation control group,the levels of LVEDP and BNP of epinephrine,sub-hypothermia and combined treatment groups were gradually increased obviously,while ±dp/dt max and MAP were decreased significantly after successful CPR. The levels of LVEDP and BNP at any time point in the combined treatment group were markedly less than those of the epinephrine and sub-hypothermia groups,and along with the time extension,the level of LVEDP had a tendency of elevation,and the level of BNP had a tendency of gradual decrease,reaching peak and valley values respectively at 240 minutes after CPR〔LVEDP (mmHg,1 mmHg=0.133 kPa):6.56±0.21 vs. 12.57±0.33,9.54±0.24,BNP(ng/L):199±19 vs. 286±14, 251±29,all P<0.01〕,at each time point,the ±dp/dt max and MAP levels were significantly higher than those in epinephrine and sub-hypothermia groups,and they were gradually decreased with the time prolongation,reaching valley values at 240 minutes after CPR〔+dp/dt max(mmHg/ms):4 229±353 vs. 2 055±311,3 224±158,-dp/dt max(mmHg/ms):3 587±168 vs. 1 315±189,2 357±245,MAP(mmHg):82.02±1.81 vs. 44.15±1.17, 56.79±1.60,all P<0.01〕. Conclusion Huangqi injection associated with a combined treatment has obvious protective effects on heart after CPR in rabbits,and the mechanism may be related to improvement of hemodynamics indexes and inhibition of excessive expression of BNP.

Objective To discuss the distribution of traditional Chinese medicine (TCM) syndromes of patients with congestive heart failure (CHF) commonly seen in clinic based on data mining technology.Methods A multicenter study was conducted. 1 451 in-patients with CHF in 4 grade Ⅲ hospitals from December 2010 to September 2012 were enrolled. The cluster and factor methods were applied to synthetically analyze the data concerning the patients' information of four diagnostic methods in TCM, and the TCM syndromes commonly seen in patients with CHF and the preliminary diagnostic scheme were summarized.Results In these 1 451 cases, there were 43 items having been experienced standardization, including clinical symptoms and manifestations of tongue and pulse, and in the information concerning four diagnosis in TCM, there were 14 items whose incidences > 10%. The incidence of chest distress was the highest 89.18% (1 294 cases), followed by shortness of breath 66.16% (960 cases), and the lowest constipation 12.20% (177 cases). There were 4 commonly seen syndromes of CHF as follows: qi deficiency blood stasis syndrome (the major diagnostic bases: palpitation, shortness of breath, dark and red tongue with white fur, thin pulse; and the minor bases: chest distress and thin fur), yang deficiency water diffusion syndrome (major bases: edema of lower limbs, cough, expectoration, difficult urination, chilly, poor appetite, greasy fur, string pulse; minor bases: body strength weakness), phlegm heat obstructing lung syndrome (major bases: chest pain, cough and dyspnea in semi-reclining position, constipation, light tongue with yellow fur, deep, slippery or rapid pulse; minor bases: dizziness), and qi yin deficiency blood stasis syndrome (major bases: dry mouth, night sweating, frequent urination at night, teeth-marked tongue, purplish tongue, uneven or irregular pulse; minor bases: loose stool, headache, purplish lips, swollen tongue with little fur, moderate or weak pulse). The load intervals of each of the symptoms in CHF qi deficiency blood stasis syndrome were from -0.520 to 0.881, all the absolute values were greater than 0.520, and the common degrees extracted were 64.3% - 83.6%, which meant the 5 common factors could extract the original index information all over the common degree 64.3%. In yang deficiency water diffusion syndrome, the load intervals of each of symptoms were from0.732 to 0.983, all the absolute values were greater than 0.732, and the common degrees extracted were 58.2% - 96.9%; in phlegm heat obstructing lung syndrome, the load intervals of each of symptoms were 0.670 - 0.992, the all absolute values were greater than 0.670, and the common degrees extracted were 52.0% - 98.5%. In qi yin deficiency blood stasis syndrome, the load intervals of each of symptoms were 0.576 - 0.926, all the absolute values were greater than 0.576, and the common degrees extracted were 54.2% - 87.1%.Conclusion By application of data mining technology combined with clinical practice, the common TCM syndromes of patients with CHF can be analyzed objectively and comprehensively.

Objective To investigate the significance of digital tomosynthesis (DTS) for suspicions lesions in the physical examination of the chest.Methods Totally 1 000 physical examinees were divided into two groups,with 500 younger ones in one group and the remained 500 ones in the other.The examinees underwent examination with digital X-ray radiography,and then the suspicious cases went through DTS examination to analyze the detection rate of pulmonary positive results.Results There were 110 suspected cases found by digital X-ray radiography,including 8 young ones and 102 old ones.The suspected cases went through DTS examination,and totally 92 nodules were found including 4 ones in the young persons and 88 ones in old persons.CT examination found 89 carcinomatous nodules in the 92 ones.Conclusion DTS examination can detect the lesion of the physical examinee,and lays a foundation for early diagnosis and treatment.

Objective To determine the capability of echocardiography to identify primary cardiac valve myxomatous degeneration (PCVMD) compared to pathological findings and to determine the echo features of PCVMD. Methods Echocardiograms were retrospectively compared with pathological findings of 1080 patients who underwent surgery for moderate or severe valve regurgitation. PCVMD of the mitral,aortic and tricuspid valves was retrospectively identified, with a comparison of the echocardiography and pathology findings,to calculate the prevalence of PCVMD,and to summarize its echocardiography features.Results A total of 104 patients were diagnosed with PCVMD (prevalence of 9. 62%) with 117 lesions.Valvular regurgitation were confirmed by echocardiography in all patients( 100 % ). Valve morphology change including valve prolapsed, valve thickening and redundancy were confirmed by echocardiography in 101 lesions(86.3 % ), but suggestive diagnosis were done by echocardiography in only two patients. Conclusions In patients undergoing surgery for valvular regurgitation,a high prevalence of PCVMD was found. PCVMD had distinctive echocardiographic features,suggesting its preoperative diagnosis.
