Objective To inspect the therapeutic effect and prognosis of treating Unstabled Angina Pectoris (UAP) with drugs and interventional methods.Methods 40 patients were treated randomly with PTCA and stenting or traditional drugs: Beta blockers, Calcium resistants, Ester nitrates, Asprin, Heparin and so on.Compared degrees of angin pectoris, cases of AMI, mortality arising from heart disease or no heart disease before and 8 months after the treatment. Results Happening of AMI and mortality in interventional group were less than those of drugs group. Distinctly improving rate of clinical effect of the former was much more than that of the later.Conclusion In short term interventional treatment (PTCA and stenting) were piror to drugs in therapeutic effects and improving prognosis.

10 mm) treated by CBA or BA were retrospectively analyzed. CBA was used in 74 patients and BA in 43 patients. Results Initial success (residual restenosis ≤30% with no major complications) was achieved in 99% of cases in CBA group and 100% in cases of BA group. Follow-up angiography was performed in all patients at (5.8?1.6) months. The diameter stenosis percent after CBA was lower and the instant gain after CBA was larger than that after BA (11.81%?9.17% versus 26.33%?10.04% and 1.96?0.51 mm versus 1.51? 0.54 mm, respectively; P

Objective To explore the value of color Doppler ultrasonography and plasma D-dimer in diagnosis of lower limb deep venous thrombosis (DVT).Methods The clinical data of 70 cases of patients with lower limb DVT diagnosed clinically were retrospectively studied.The lower limb venous of each patient was examined by color Doppler ultrasonography and the plasma level of D-dimer were measured,furthermore the plasma levels of D-dimer in different phase and different type of thrombosis were compared.Results The sensitivity,specificity,positive predictive value,negative predictive value,and accuracy of plasma D-dimer and ultrasonography examination in lower limb DVT were 100%,66.7%,97.0%,100%,and 97.1%,and 98.4%,83.3%,98.4%,83.3%,and 97.1%,respectively.The plasma D-dimer in acute phase 〔(6 451?4 012.22) ?g/L〕 and subacute phase 〔(2 063?1831.35) ?g/L〕 of lower limb venous thrombosis were significantly higher than that in normal control group 〔(310?66.70) ?g/L〕,P

Objective To observe the influence of insulin resistance(IR) and isosorbide mononitrate(ISMN) on myocardial cellular apoptosis in spontaneously hypertensive rats (SHR) .Methods Forty male 14‐week old Wistar(W) rats and SHR(S) each were respectively or jointly fed with normal diet (ND) ,high fat and high glucose(HFHG) diet ,normal saline(NS)and ISMN by ga‐vage .Then they were randomly divided into the normal and NS group (normal W and normal S ) ,HFHG and NS group(HFHG W and HFHG S) ,normal and ISMN group(ISMN W and ISMN S) ,HFHG and ISMN group(HI W and HI S) ,with 10 rats in each group .After 12‐week feeding ,carotid arterial blood was collected for detecting blood glucose concentration and insulin level and cal‐culating insulin resistance index (HOMA‐IR);4 myocardial tissue samples were taken for respectively observing the morphology under microscope ,and detecting the NO level ,myocardial Bcl‐2 ,Bax gene and their protein expression levels in myocardial tissue . Results Myocardial NO level ,Bax gene mRNA and related protein levels in the HFHG and ISMN intervention groups were higher than those in the normal group ,while the bcl‐2 gene mRNA and related protein expression were on the contrary ;myocardial tissue NO level ,Bax gene mRNA and related protein expression in the S groups were increased compared with the corresponding W groups ,while the bcl‐2 gene mRNA and related protein expression were on the contrary ;in the HFHG W group ,the myocardial tis‐sue NO level had significantly positive correlation with HOMA‐IR ,and in the ISMN W group ,HOMA‐IR was positively correlated with the NO level in the myocardial tissue .Conclusion Myocardial cellular apoptosis of SHR is increased compared with Wistar rats ;both IR and ISMN can aggravate the apoptosis of SHR myocardial cells ,moreover IR has a mutual induction and reciprocal causation with ISMN .

Objective To evaluate the application value of prehospital index (PHI) in hospitalized patients with acute trauma.Methods A study was done in 1802 hospitalized patients with acute trauma by random sampling.PHI and injury severity score (ISS) were made respectively.Receiver operating characteristic curve (ROC curve) was used for detecting optimal cut-off point by taking the date of discharge as the endpoint and the outcome as observed indicator.In order to compare the predicting prognosis value of PHI in hospitalized patients with acute trauma,the corresponding predicting indicators were calculated and ISS was used for reference.Results The area under the ROC curve was 0.871 (95％ CI:0.855-0.886) by the score of PHI and 0.792 (95％ CI:0.773-0.811) by the score of ISS,and there was statistically difference between the two scoring systems (Z =2.674,P =0.007),and the optimal cut-off point was used for judging the potential for critically ill patients when PHI was ≥ 4,ISS ≥ 22.The sensitivity predictors of critically ill patients death of PHI was superior to ISS (x2 =6.975,P =0.008),the specificity and the accuracy of PHI and ISS showed no significant difference (P ＞ 0.05).Conclusions PHI has high potential for assessing patient condition and predicting the death of hospitalized patients with acute trauma,and it is equivalent to ISS in prediction value.The advantages of PHI are simple in operation,easy to learn,reflecting the condition timely and reliably,suitable for dynamic evaluation and comparison,which is suitable for critical patients with trauma of preliminary screening.

Objective To evaluate the value of non invasive examinations in the diagnosis of vascular disease of lower extremity. Methods Segmental systemic pressure (SEG), pulse volume recorder (PVR) and continuous wave (CW) were adopted to examination of 36 patients with arterosclerosis obliterans of lower limbs, and the foundings were compared with that of MRA and operation . Results In all 36 cases, non invasive examinations detected abdominal aorta and common iliac artery with femoral artery occlusion in 12 cases ,femoropoplitea artery occlusion in 28 cases, popliteal artery and the distal artery occlusion in 16 case; MRA together with operation confirmed abdominal aorta and common iliac artery with femoral artery occlusion in 11 cases, femoropopliteal artery occlusion in 32 cases and popliteal artery and the distal artery occlusion in 13 cases. The accurent diagnosis rate of non invasive examination was 85.7%. Conclusions Although PVR has not yet been used to replace the arteriography to directly observe the local situation of arterial lesions , it can preliminarily determine the obstruction sites and severe degree of the occluded arteries. PVR has convenient and reliability in the diagnosis,evaluation of the therapeutic effect and the postoperative follow up of blood vessel diseases,it is worthy to be widely applied in the clinical practice.

The main clinical symptoms of the patients are upper gastrointestinal tract haematemesis,hypersplenotrophy and hypersplenia.Most cases can be detected by ultrasonography,digital subtraction angiography(DSA),multislice CT(MSCT) or magnetic resonance angiography(MRA).Rex surgery,Hassab surgery or combination the shunt and disconnection combined operation et al are the preferred operation,therapy for children's cavernous transformation of portal vein will be further developed.The relevant literatures were collected in recent years to review the advancement of surgical therapy for children's cavernous transformation of portal vein.

Objective To study the utility and feasibility of CRAMS score to assess prognosis of patients with acute trauma.Methods A retrospective review of 1 802 patients with acute trauma was conducted to calculate CRAMS and ISS score.Receiver operation characteristic curve (ROC) was used to measure the prognostic role of CRAMS in comparison with ISS.Results Area under the curve (RUC) was 0.885 for CRAMS (95 ％ CI 0.870-0.900) and was 0.792 for ISS (95％ CI 0.773-0.811),with statistical difference of the two scoring systems (Z=4.280,P ＜0.01).To identify patients with potential critical illness,optimal cut-off point was≤7 for CRAMS and≥24 for ISS.CRAMS presented better sensitivity (x2 =16.910,P ＜ 0.01),but lower specificity (x2 =5.260,P ＜ 0.05) and accuracy (x2 =0.693,P ＞ 0.05) for predicting mortality when compared with ISS.Conclusions CRAMS is better than ISS in predicting prognosis for patients with acute trauma and exhibits a high discrimination.RAMS has advantages of simple operation,easy grasping and accurate and timely reflection of illness severity,which facilitates the early detection and treatment of critical illness in inhospital trauma patients.
