Objective To research the curative effect of the chronic refractory skin ulcer,which belong to yang deficiency of both spleen and kidney type with the treatment of Huiyang Shengji ointment,and discuss the mechanism at cell and molecular level.Methods According to the diagnostic criteria,102 patients were divided into the treatment group(treated with topical Huiyang Shengji ointment) and the control group(treated with topical chlorhexidine).The effects were summarized six weeks later.The marginal tissue of the patients with the chronic skin ulcer was taken to analyze collagen Ⅰ/Ⅲ with the software and the expression of cytokine FGF-2,VEGF,Fn were observed during the wound heal.Results The effective rate was 50% in the treatment group,the control group was 33.33%,with statistical differences.Huiyang Shengji ointment can change the status of the chronic wound,promote growth of new blood vessels and improve the collagen synthesis,especially collagenⅠ.The expression of the FGF-2 and VEGF in the marginal tissue of the chronic skin ulcer showed a rising trend.Conclusions Huiyang Shengji ointment can accelerate the wound heal of chronic refractory skin ulcer.One of the mechanisms is related to promoting growth of new blood vessels and improving the collagen synthesis.

Objective To evaluate the risk factors,diagnostic index of the restrictive right ventricle physiology(rRV) and the impact of the mid-term outcome of the patients.Methods Eighty patients(30 in rRV group and 50 in non-rRV group) undergoing TOF repair admitted in our department from Oct 2011 to May 2012 were studied.Perioperative clinical data were collected and echo data were recorded after operation.Mixed linear regression for repeated measures was used to compare the variables and analyze the correlations.Results Patients in rRV group were younger with longer cardiopulmonary bypass(CPB) time,aortic cross clamp time,ventilation time,intensive care unit and hospital stay compared with those in non-rRV group(P<0.01,respectively).The younger patients with longer CPB time had high risk of rRV by logistic regression analysis.Within 7 days post operation,the increase of saturation of venous oxygenation and decrease of oxygen extraction ration were slower in rRV group than those in non-rRV group(P<0.05,respectively).Lactate decreased in both groups,but was higher in rRV group throughout the 7 days(P=0.03).NT-proBNP was higher in rRV group throughout the 7 days than that in non-rRV group.NT-proBNP≥4750pg/ml often indicated the patients in the state of rRV.CRP slightly increased in 1-2 days post operation,and decreased thereafter,and the decrease was slower in rRV group(P=0.08).With regard to the mid-term outcome,there was no significant differences in the incidences of the obstruction of the right ventricle outflow and main pulmonary artery,the stenosis of the branch of pulmonary artery and the degree of the pulmonary valve regurgitation.Conclusion rRV is associated with significantly higher levels of NT-proBNP and CRP.The incidence of rRV correlates with age on operation and positively correlates with CPB time.NT-proBNP would be regarded as an indicator of the incidence of rRV.The study indicated the rRV would have impact on the early outcome of the patients but there was no significant effect on mid-term outcome.

OBJECTIVE To analyze the value of modified sinus CT score in olfactory function evaluation before and after functional endoscopic sinus surgery in chronic rhinosinusitis with nasal polyps(CRSwNP). METHODS Fifty-four patients who underwent functional endoscopic sinus surgery for CRS with nasal polyps were enrolled in this prospective study by inclusion criteria and exclusion criteria. T&T methods and olfactory function VAS were used to analyze the subjective olfactory function and were performed preoperatively and at 6 months after surgery. In modified sinus CT score, middle turbinate and superior turbinate associated olfactory cleft areas were used to evaluate the anterior olfactory cleft score(AOCS) and posterior olfactory cleft score(POCS). Sinus CT scans Lund-Mackay scores were also collected before surgery. The correlation between the status of the olfactory cleft on CT, Lund-Mackay score and the preoperative and postoperative olfactory results were investigated.RESULTS Among 54 patients, there were 36 male and 18 female, with average age of 47.9 years old(from 24 to 67 years). There were 30 patients followed 6 months after surgery. The findings of olfactory cleft opacification and the CT Lund-Mackay scores had a positive correlation with preoperative olfactory results(P<0.001). The olfactory cleft opacification showed a stronger correlation with the preoperative olfactory results than the CT Lund-Mackay score. The AOCS was more significantly correlated with the postoperative olfactory results than the other parameters.CONCLUSION Preoperative CT findings, especially the anterior portion of the olfactory cleft had a statistically significant association with the postoperative olfactory results in patients with CRS with nasal polyps.

ObjectiveTo investigate the effects of aconitine, mesaconitine and hypaconitine on calcium release in isolated adult rat cardiac myocytes.MethodsThe left ventricular cardiac myocytes isolated from adult Sprague-Dawley rats were perfused withacnitine, mesaconitine and hypaconitine at 0.3 μmol/L, 1μmol/L, 3 μmol/L for 12 min. The spontaneous calcium release (SCR) rate, the end-diastolic[Ca2+](F0) and the calcium transient amplitude (ΔF) were detected 4 min, 8 min and 12 min after the perfusion. 12 min after the perfusion with acnitine, mesaconitine and hypaconitine at 0.3 μmol/L, the changes of systolic dynamics and calcium transient were detected for the positive inotropic effect. Results Any of aconitine, mesaconitine and hypaconitine induced SCR, mesconitine-induced SCR rate was highest at low concentration (0.3 μmol/L), and aconitine-induced SCR rate highest at high concentration (3 μmol/L). Compared with the control, 12 min after the perfusion with acnitine, mesaconitine and hypaconitine at 3 μmol/L elevated F0 (1.459 ± 0.379, 1.585 ± 0.493, 1.213 ± 0.254vs.1.079 ± 0.108, allP<0.05) and ΔF(1.615 ± 0.455, 2.210 ± 0.756, 1.528 ± 0.422vs. 1.036 ± 0.125, allP<0.05), mesaconitine with ΔF higher than aconitine and hypaconitine. At low concentration (0.3 μmol/L), compared with control, aconitine, mesaconitine and hypaconitine increased ΔF (0.409 ± 0.127, 0.423 ± 0.107, 0.414 ± 0.118vs.0.260 ± 0.065;P<0.05 orP<0.01) and contraction amplitudes (5.464% ± 2.239%, 7.449% ± 2.548%, 5.524% ± 1.645%vs.3.428% ± 0.911%;P<0.05 orP<0.01), prolonged the time to peak of calcium transient (0.041 ± 0.016 s, 0.039 ± 0.009 s, 0.038 ± 0.011 svs.0.032 ± 0.007 s;P<0.05 or P<0.01); compared with aconitine, mesaconitine and hypaconitine decreased calcium transient time constant (0.301 ± 0.054 s, 0.324 ± 0.064 svs.0.361 ± 0.076 s;P<0.05 orP<0.01) and diastolic t50 (0.124 ± 0.035 s, 0.126 ± 0.040 svs.0.157 ± 0.056 s;P<0.05 orP<0.01).ConclusionsAconitine, mesaconitine and hypaconitine reveal the positive inotropic effects couple with the toxic effects. Increased[Ca2+]in cardiac myocytes is the key factor for the positive inotropic effects, but also the risk factor for SCR.

Objective To investigate the protective effects of different Chinese medical treatments on myocardial ischemia-reperfusion injury in rats. Methods 60 SD rats were divided into 5 groups randomly: a sham-operated group, a model group, a removing phlegm and enlarging chest group, an activating blood and dissolving stasis group, and a treating both phlegm and blood stasis group. The model of MI/RI of the myocardium was reproduced by ligation of left descending artery for 30min followed by releasing the ligation for 2 hours in rats. Serum contents of LDH-L, CK were measured , TNF-αand ICAM-1 expressions in myocardium were determined with immunohistochemistry and myocardial ultrastructure at the ischemia region was observed with the transmission electron microscope after myocardial reperfusion injury. Results Compared with the model group, LDH-LXK and TNF-αICAM-1 levels were lower, myocardial ultrastructural changes were improved in all the other four groups treated by different Chinese medicine (P<0.01 or P<0.05), especially in the group treating both phlegm and stasis. Conclusion The removing phlegm and enlarging chest method, activating blood and dissolving stasis method, treating both phlegm and blood stasis method can protect myocardium from M1/R1, especially the method of treating both phlegm and blood stasis.

Objective To discuss factors influencing the heterotopic ossifications (HO) after treatment of bi-column acetabular fractures. Methods One hundred and ninety-three cases of bi-column acetabular fractures were followed up, including 147 males and 46 females with an average age of 34. 4 years. Thirty-one cases were associated with craniocerebral trauma. The interval between injury and surgery was less than 1 week in 15 cases, 1 to 2 weeks in 121 cases, 2 to 3 weeks in 34 cases, and over 3 weeks in 23 cases. Factors that might have influenced HO, including surgical method, associated injury, and interval between injury and surgery, were analyzed retrospectively. Results All the cases were followed up for an average of 44. 2 (14 to 84) months. The mean operation time was 238 (150 to 330) minutes, and the average blood loss was 1453 (450 to 4400) mL. The incidence rate of HO was 39. 9% (77 in 193 cases), including 39 cases of degree one, 23 cases of degree two, and 15 cases of degree three. Of the 77 cases associated with HO, 14 had craniocerebral trauma and 63 did not (χ~2 = 0. 019, P = 0. 891) . HO was found in 2 cases that had been operated on in less than 1 week, 38 cases in 1 to 2 weeks, 21 cases in 2 to 3 weeks, and 16 cases in over 3 weeks. The Spearman correlation analysis between HO degree and clinical result showed no correlation ( R = 0. 041, P =0. 722). Only 15 cases (7. 8% ) were associated with HO after the debridement of the necrotic gluteus minimus. Conclusions HO after surgery for bi-column acetabular fractures may not be correlated with craniocerebral trauma, but highly correlated with the interval between injury and surgery. Debridement of necrotic gluteus minimus and other muscles can reduce the incidence of HO.

Objective:To investigate the effects of Xiaoyu-Jiangzhi capsules on blood lipid, carotid artery atherosclerosis (CAA) and plaque in apolipoprotein E knockout (ApoE -/-) mice. Methods:The ApoE -/- mice were fed with high-fat food to establish carotid atherosclerosis model. The ApoE -/- mice were randomly by weight divided into model group, Atorvastatin group, low- and high-dose Xiaoyu-Jiangzhi capsules group. The C57BL/6cnc mice were used as control group and fed with normal diet. The Atorvastatin group was given atorvastatin suspension 1.3 mg/kg, low and high dose groups were given Xiaoyu-Jiangzhi capsule suspension 325 and 975 mg/kg, and the control group and model group were given equal volume of distilled water. The mice were gavaged with 0.1 ml/10 g body weight, once a day, and the weight of mice was recorded weekly. After 12 weeks of continuous intragastric administration, the blood lipid and liver /body weight index of the mice were measured. Carotid arteries were sliced to conduct oil red O staining and VG staining for the pathological analysis. Results:After 12 weeks of drug administration, the weight of mice in the high-dose group was significantly lower than the model group. The level of TC (25.92 ± 4.21 mmol/L vs. 30.39 ± 4.67 mmol/L) and LDL-C (7.97 ± 2.14 mmol/L vs. 10.26 ± 1.97 mmol/L) in the high-dose group significantly decreased ( P<0.05), the level of HDL-C in the low and high-dose group significantly increased ( P<0.05). The pathological results showed that after 12 weeks of administration, the carotid artery lipid deposition blockage rate in the Atorvastatin group and the high dose group were significantly smaller than the model group( P<0.05), and no vascular plaque has been formed. Conclusion:The Xiaoyu-Jiangzhi capsules could reduce LDL-C, increase HDL-C levels, reduce the constriction of arterial stenosis and slow down the formation process of carotid plaque.
