Objective To observe the effects of electroacupuncture on genu recurvatum after stroke. Methods 80 stroke patients with genu recurvatum were randomly assigned to treatment group (n=40) and control group (n=40). The control group accepted routine rehabilitation, and the treatment group accepted electroacupuncture at Yanglingquan (GB34), Futu (ST32), Weizhong (BL40), Chengshan (BL57) and Zusanli (ST36) in addition, for 30 days. The incidence of effectiveness was compared between groups. All the patients were assessed with range of motion (ROM) of knee and Fugl-Meyer Assessment of lower limbs (FMA) before and after treatment. Results The incidence of effectiveness was 72.5% in the treatment group, which was more than 55% in the control group (P<0.05). The ROM and score of FMA improved more in the treatment group than in the control group (P<0.05). Conclusion The electroacupuncture can promote the recovery of genu recurvatum after stroke.

OBJECTIVETo discuss the clinical effect of closed reduction and interlocking intramedullary nailing in the treatment of femoral shaft fracture.

METHODSFrom March 2006 to December 2011,103 patients with femoral shaft fracture were treated by closed reduction and interlocking intramedullary nailing including 76 males and 27 females with an average age of 36 years old ranging from 19 to 55 years old. According to AO classification,there were 64 cases with type A,27 with type B, 12 with type C. Thirteen cases were open fractures including 5 cases with Gustilo type I , 8 with Gustilo type II . The time of bone healing were observed after operation, the knee function recovery was evaluated by HSS scoring standard at 1 year after operation.

RESULTSThe intraoperative complications included femoral neck fracture in 1 case and proximal femoral fracture in 1 case,both of the patients were treated with reconstructive intramedullary interlocking nail and the fractures healed postoperatively. One patient was suffered from common peroneal nerve injury,which were fully recovered at 4 months later after medical treatment. All the patients were followed up from 12 to 28 months (averaged 22 months). All of the fractures were healed well and the average healing time was 3 to 9 months (averaged 5 months). All the hip joints were recovered to normal function. The average HSS was 90.89±5.06 at 1 year after operation.

CONCLUSIONInterlocking intramedullary nailing is the preferred treatment for patients with femoral shaft fracture. Carefully operating and closed reduction can reduce the complications.

OBJECTIVETo determine if multi-detector CT (MDCT) characterization of plaque is correlated with the classification of acute coronary syndrome (ACS).

METHODSAltogether 1900 patients were examined by MDCT from December 2007 to May 2009, of whom 95 patients fulfilled the criteria of ACS. Those patients were divided into the discrete plaque group ( n=61) and diffuse plaque group ( n=34) based on the findings in MDCT. The clinical diagnosis of ACS and CT results were analyzed, including segment stenosis score, segment involvement score, 3-vessel plaque score, left main score, calcification score, and remodeling index. The incidences of major adverse cardiac events in follow-up period were also recorded.

RESULTSThe patients of the diffuse plaque group were older than those of the discrete plaque group ( Pü0.0001). The diffuse plaque group presented more cases of hypertension, peripheral artery disease, diabetes, and heart failure than discrete plaque group (all P<0.05). All the 5 patients with ST-segment elevation myocardial infarction were found in discrete plaque group. The segment stenosis score of the discrete plaque group was lower than that of the diffuse plaque group(5.15±3.55 vs. 14.91±5.37, Pü0.001). The other four scores demonstrated significant inter-group difference as well (all P<0.05). The remodeling index of thediscrete plaque group was higher (1.12±0.16 vs.0.97±0.20, Pü0.05). Follow-up data showed that major adverse cardiac events occurred more frequently in diffuse plaque group than in discrete group (29.41% vs. 11.48%, P=0.0288).

CONCLUSIONSCharacteristics of discrete and diffuse plaques may be significantly different among different classes of ACS. The diffuse plaque may present higher risk, correlated to higher mortality. The diagnosis of discrete and diffuse plaques by MDCT would provide a new insight into the prognosis and treatment of ACS.

Objective To investigate the relationship between blood pressure variability (BPV) and left ventricular diastolic function in patients with essential hypertension.Methods Left ventricular diastolic function of 252 hypertensive patients were assessed by early (E) diastolic transmitral flows to early diastolic mitral annular velocity (Ea) (E/Ea) ratio derived from Doppler echocardiography.Patients were divided into two groups according to normal left ventricular diastolic function group (E/Ea ＜ 15,n =168) and left ventricular diastolic dysfunction group (E/Ea ≥ 15,n =84).All patients were monitored by ambulatory blood pressure.Standard deviation (SD) and coefficient of variation (CV) of blood pressure were calculated as the BPV.Relationship between BPV and left ventricular diastolic function were analyzed by multivariate logistic regression analysis.Results All-day average diastolic blood pressure(DBP),the day systolic blood pressure (SBP),night SBP,night DBP,SBPSD,DBPSD and DBPCV in the left ventricular diastolic dysfunction group were significantly higher than in the normal diastolic function group (all P ＜ 0.05).Multivariate logistic regression analysis showed that left ventricular diastolic dysfunction was associated with SBPSD (OR:1.126,95 ％ CI:1.054-1.203,P ＜ 0.01),SBPCV (OR:1.127,95 ％ CI:1.036-1.225,P ＜ 0.01) in this patient cohort.Conclusion High variability of SBP is correlated with left ventricular diastolic dysfunction in hypertensive patients.

OBJECTIVETo explore the effects of retinol acid (RA) and triiodothyronine (T3) on alleviating the impairment of cognitive function by sleep deprivation (SD).

METHODSMale Wistar rats were divided into 4 groups: control group (C group), sleep deprivation group (SD group), sleep deprivation + RA group (SD + RA group) and sleep deprivation + T3 group (SD + T3 group). Open field test (OFT) was used to observe the nervous behavior of the rats after SD and electrophysiological brain stereotactic method was used to test long-term potentiation (LTP) in dentate gyrus (DG) of the rats. Ng protein expression was determined by Western blot.

RESULTSCompared with the SD group, the number of crossing in OFT, the changes of amplitude of population spike (PS) and the expression of Ng protein in hippocampus were higher significantly in the SD + RA and SD + T3 groups. All of these had not significant difference comparing with the C group.

CONCLUSIONRA and T3 may alleviate the restrain state of neural system after SD by augmenting the expression of Ng protein in hippocampus.

Objective To observe the changes of the pulmonary ventilation(VE)volume under different exercise intensities along with time,and to explore the best time for measuring VE under different intensities of exercise.Methods Sixty-one young mals were selected as subjects,who engaged in exercise of different intensities on the cycle ergometer(20, 40, 60, 80, 100, 120, 140, 160, and 180 W).The duration of exercise of each intensity was 6 minutes,the cardiopulmonary function was detected using a portable instrument,and real time monitoring of VE changes was enforced. Results (1)For exercise of intensity 20 W, VE initially increased fast with time, but after 1 min,it ceased to rise and remained stable.There was no significant difference at 1 min and afterwards(P>0.05).(2)The case was the same with exercise of the intensity 40 and 60 W.(3)For intensities of 80,100,120,140,and 160 W,VE became stable at 3 min. (4)For exercise of intensity 180 W,VE became stable at 4 min.Conclusion The time taken for VE to achieve stability under different intensities is different,which is positively correlated with the intensity of exercise.The greater the intensity of exercise,the longer it takes to achieve stability.

Objective To evaluate the clinical efficacy and safety of Dan-shen dripping pill combined with atorvastatin calcium in the treatment of type 2 diabetic mellitus with carotid atherosclerosis.Methods Ninety patients of type 2 diabetic mellitus with carotid atherosclerosis were randomly divided into control group ( n =40 ) and treatment group ( n=50 ).Patients in the control group were treated with atorvastatin cal-cium 10 mg, once per night for 3 months.Patients in the treatment group were treated with Danshen dripping pill 270 mg, tid combined with ator-vastatin calcium 10 mg, once per night for 3 months.The clinical effica-cy, blood lipid, vascular endothelial function, bilateral carotid intima-media thickness, plaque area, and adverse drug reactions were compared between two groups.Results After treatment, total effective rate in treatment group was significantly higher than that in control group (92.00% vs 82.50%, P<0.05 ).By comparison with control group, the blood lipid levels in treatment group was significantly lower, vascular endothelial function was improved, bilateral carotid plaque area and ca-rotid intima -media thickness were significantly lower ( P <0.05 ).There were no adverse drug reactions occurred between two groups during the treatment.Conclusion Danshen dripping pill combined withatorvastatin calcium can significantly decreases the level of blood-lipid, improve the symptom of carotid atherosclerosis and the endothelial function for the type 2 diabetic mellitus patients.

OBJECTIVETo assess the feasibility and accuracy of CT coronary angiography (CTCA) combined with adenosine stress myocardial perfusion scintigraphy (MPS) for diagnosis of flow-limiting coronary stenosis.

METHODSA total of 105 patients with suspected or established coronary artery disease (CAD) underwent CTCA and MPS within 4 weeks before invasive coronary angiography. The accuracy of CTCA/MPS in the diagnosis of flow-limiting coronary stenosis was evaluated in comparison with the results of quantitative coronary angiography and MPS.

RESULTSThe sensitivity, specificity, positive predictive value and negative predictive value of CTCA/MPS as a combined approach for detection of flow-limiting coronary stenosis were all 100%. In 16% (9/55) of the patients, revascularization procedures were performed and no flow-limiting stenosis was found.

CONCLUSIONCombination of CTCA and MPS has an excellent accuracy for detecting flow-limiting coronary stenosis as compared with quantitative coronary angiography/MPI, and can be a useful gatekeeper for revascularization procedures.
