Objective To evaluate the therapeutic effect of oral and external application of Chinese medicine combined with Ilizarov external fixator and the accordion technique for severe chronic osteomyelitis of the tibia.Methods A total of 78 patients with severe chronic osteomyelitis of the tibia were randomized into a routine treatment group and a combined treatment group, 39 in each group. All the patients in the two groups received external fixation by use of Ilizarov external fixator and the accordion technique. All the patients in the combined treatment group received oralGuyu decoction. The patients who had large wound received vacuum-sealing drainage in the routine treatment group, and vacuum-sealing drainage combined with external application ofShengji-Yuhong plaster in the combined treatment group. All the patients were treated for 8 weeks and followed up for 2 years. The time to wound healing and fracture healing, and the drainage time were compared between the two groups. Functional and radiologic findings were evaluated according to Paley's criteria. The functions of the knee joint and ankle joint were evaluated using the Hospital for Special Surgery (HSS) knee score and the scoring system of Baird and Jackson, respectively.Results The time to wound healing (17.33 ± 6.21 dvs. 22.27 ± 8.12 d;t=3.018,P=0.004) and the time to fracture healing (32.25 ± 6.02 weeks vs. 36.37 ± 7.75 weeks;t=2.623,P=0.011), and the drainage time (17.01 ± 4.66 dvs. 21.51 ± 5.23 d;t=4.012, P<0.001) in the combined treatment group were significantly shorter than those in the routine treatment group. According to Paley's criteria, the patients who achieved a score of excellent or good for fracture healing (84.6%vs. 53.8%;χ2=7.282,P=0.007) and function (92.3%vs. 66.7%;χ2=6.369,P=0.012) in the combined treatment group were significantly more than those in the routine treatment group. The scores of the HSS knee score (84.56 ± 7.42vs. 78.81 ± 5.33;t=3.391,P=0.002) and the scoring system of Baird and Jackson (85.01 ± 8.21vs. 79.21 ± 6.78;t=3.402,P=0.024) in the combined treatment group were significantly higher than those in the routine treatment group.Conclusion OralGuyu decoction and external application ofShengji-Yuhong plaster combined with Ilizarov external fixator and the accordion technique can promote recovery of the joint function, fracture healing and wound healing.

Objective:To evaluate the effects of Sander Ⅱ appliance in the orthodontic treatment of adolescent ClassⅡmalocclusion. Methods:15 cases (6 male and 9 female)of adolescent ClassⅡ malocclusion with mandibular retrution were treated with Sander Ⅱappliance.Pre-treatment and post-treatment Lateral cephalogram measurements were traced and analyzed in terms of 28 indicators. SPSS 19.0 software package was used for paired t test.Results:After treatment,15 patients achieved remarkable improvement in the maxillofacial profile and normal overjet of teeth.The cephalometric analysis showed that ANB,OJ,H°and U1-E decreased(P <0. 05),SNB,B-OLP,Pg-OLP(mm),Ii-OLP,Ms-OLP(mm),Mi-OLP(mm),N-Me,ANS-Me,S-Go,Go-Gn,N'-Pg'/FH,Cm-Sn-Ls and Pg-Pg'increased(P <0.05).There was no significant change in SN-MP,SN-OL and Y-axis before and after treatment. Conclusion:Sander Ⅱ appliance is effective in the treatment of adolescent early Class Ⅱmalocclusion.

The volume-time curve change in patients with normal left ventricular (LV) diastolic function and diastolic dysfunction was evaluated by real-time three-dimensional echocardiography (RT3DE). LV diastolic dysfunction was defined by E'＜A' in pulse-wave tissue Doppler for inter-ventricular septal (IVS) of mitral annulus. In 24 patients with LV diastolic dysfunction, including 12 patients with delayed relaxation (delayed relaxation group) and 12 patients with pseudo-normal function (pseudo-normal group) and 24 normal volunteers (control group), data of full-volume image were acquired by real-time three-dimensional echocardiography and subjected to volume-time curve analysis. EDV (end-diastolic volume), ESV (end-systolic volume), LVEF (left ventricular ejection fraction), PER (peak ejection rate), PFR (peak filling rate) from RT3DE were examined in the three groups. Compared to the control group, PFR (diastolic filling index of RT3DE) was significantly reduced in the delayed relaxation group and pseudo-normal group (P＜0.05). There were no significant differences in EDV, ESV, LVEF, PER (P＞0.05). It is concluded that PFR, as a diastolic filling index of RT3DE, can reflect the early diastolic function and serve as a new non-invasive, quick and accurate tool for clinical assessment of LV diastolic function.

Objective: To investigate the effect of taurine on learning and memory impairment, cytokines secretion in rats intrahippocampally injected with ?-amyloid (A?) 1-40. Methods: SD rats were randomly divided into control group, A? injected group, taurine (0.3g/kg?d, 0.6g/kg?d) groups. The rats were fed with taurine for 7 days, and then subjected to bilateral intrahippocampus injection of A?1-40 or vehicle. Two weeks later, all rats performed Morris water maze test. The contents of IL-6, TNF-? were checked by way of radio-immunity assay for hippocampus samples. Results: Compared with A?model group, the escape latency and distance were significantly reduced in taurine (0.6g/kg?d) group; the ratio of swimming distance in the target quadrant to that in the whole pool of the probe trial; the content of cytokines of IL-6 and TNF-?in hippocampus were reduced significantly. Conclusion: Taurine can effectively attenuate the cognitive dysfunction caused by A?1-40 in rats. The reduced cytokines content in hippocampus might contribute to this effect.

The volume-time curve change in patients with normal left ventricular (LV) diastolic function and diastolic dysfunction was evaluated by real-time three-dimensional echocardiography (RT3DE). LV diastolic dysfunction was defined by E'0.05). It is concluded that PFR, as a diastolic filling index of RT3DE, can reflect the early diastolic function and serve as a new non-invasive, quick and accurate tool for clinical assessment of LV diastolic function.

OBJECTIVETo study the effect and mechanism of saffor injection on renal ischemia/reperfusion (I/R) injury in rats.

METHODSeventy-five SD rats were randomly divided into five groups (n = 15, in each), normal control groups, I/R control groups, low-dose treatment groups, middle-dose treatment groups and high-dose treatment groups. After rat's I/R injury model was established, renal function was assessed by measuring serum creatinine, blood urea nitrogen, urine osmotic pressure and urine osmotic pressure/blood osmotic pressure, the apoptosis rate in I/R renal tissure was measured by TUNEL method and caspase-3 concentration was measured by immunohistochemistry.

RESULTReperfusion of the ischemic kidney induced marked renal dysfunction. Saffor injection significantly inhibited the reperfusion-associated increase in apoptosis rate and caspase-3 protein absorbance value. Moreover, the renal dysfunction at all treatment groups was markedly ameliorated by Saffor injection. (P < 0.01).

CONCLUSIONThe results show that saffor injection significantly reduces the renal dysfunction and injury caused by I/R of the kidney, And the protective effect of Saffor injection may be related to the inhibition of cell apoptosis and caspase-3 gene expression following renal I/R.

OBJECTIVETo carry out expert survey for traditional Chinese medicine (TCM) syndrome characteristics of different clinical types of coronary artery disease (CAD).

METHODSBy using Delphi method, we carried out two rounds of nationwide expert surveys for modern TCM characteristics of syndrome elements and syndrome types of CAD.

RESULTSBased on expert consensus, qi deficiency, blood stasis, phlegm turbidity, qi deficiency blood stasis, and intermingled phlegm and blood stasis are common TCM syndromes for different clinical types of CAD. Of them, qi stagnation, blood stasis, phlegm turbidity, heat accumulation, cold coagulation, yang deficiency, deficiency of both qi and yang were more often seen in patients with unstable angina than in those with stable angina. Qi deficiency, yin deficiency, and deficiency of both qi and yin were less seen. We could see more excess syndrome and less deficiency syndrome (such as qi deficiency, yin deficiency, etc.) in acute ST-segment elevation myocardial infarction (STEMI) than acute non-ST-segment elevation myocardial infarction (NSTEMI). Qi deficiency, blood stasis, water retention, yang deficiency, phlegm turbidity, yin deficiency, Xin-qi deficiency, and qi deficiency blood stasis induced water retention are the most common TCM syndrome types of CAD heart failure (HF). Blood deficiency, yin deficiency, heat accumulation, deficiency of both Xin and Pi, deficiency of both qi and blood, deficiency of both qi and yin, yin deficiency and fire hyperactivity were more often seen in CAD arrhythmias.

CONCLUSIONSTCM syndrome distributions of different clinical types of CAD have common laws and individual characteristics. Results based on the expert consensus supplied evidence and support for clinical diagnosis and treatment of CAD.

OBJECTIVETo observe the thoracic aorta features in patients with bicuspid aortic valve (BAV) with echocardiography.

METHODSWe retrospectively analyzed the echocardiographic features and clinical manifestations in 273 patients with BAV detected from 1991-04 to 2006-02.

RESULTS(1) Aortic dimensions of the anulus, the sinuses of valsalva, the sinotubular junction, the ascending aorta at the level of its largest diameter of 31 patients with functionally normal BAV were significantly increased compared that in control subjects (P < 0.01 to P < 0.001) while the dimension of the descending aorta posterior to the left atrium was similar between the two groups (P > 0.05). (2) There is no relation between the vulval positions of BAV and aortic dimensions (P > 0.05). (3) The dimensions of the annulus as well as the sinuses of valsalva were negatively related to the aortic valve gradient, and the dimension of the annulus, the sinuses of valsalva and sinotubular junction were positively related to the degree of aortic regurgitation in 273 patients with BAV (all P < 0.05).

CONCLUSIONOur results show there is a hemodynamic independent thoracic aortic dilation in patients with functionally normal BAV. Gradient and aortic regurgitation are related to the dimension of the annulus, the sinuses of valsalva and sinotubular junction in patients with BAV.
