Objective:To observe the efficacy of Ionic silver dressing + gel in treating diabetic foot ulcer. Methods:43 cases of this disease were divided into two groups randomly. In treating group(A),the wounds were treated with Ionic silver dressing + gel and the wounds were treated with basic method in controlling group(B). Results:Ionic silver dressing + gel could control wound infection,promote wound granulation and epithelium regeneration and lessen inflammatory reaction. In treating group,the average wound healing time decreased to (53.18?9.49)days from (66.86?7.90)days in control group(P

Objective To evaluate the effect of early clinical interference strategies on preventing the conversion of acute pancreatitis to the severe form and aggravation of severe acute pancreatitis(SAP).Methods The patients with acute pancreatitis admitted to this hospital were divided into two therapeutic phases by different therapeutic methods from January 2001 to December 2008.Patients in the first phase(from January 2001 to December 2004) were treated by the routine management,and the second phase(from January 2005 to December 2008) by the routine management combined with early clinical interference strategies.Then,the ratio of conversion from acute pancreatitis to SAP and prognosis of SAP between two phases were compared.Results Compared with the first phase,the rate of aggravation of acute pancreatitis was significantly decreased in the second phase(4.48% vs.21.18%),the average healing time of SAP,the incidences of systemic and local complications and the mortality of pancreatitis were reduced(P

Objective To analyze the causes of rhabdomylysis (RM), pathogenetic mechanisms and possible effective interventions for secondary multiple organ dysfunction syndrome (MODS) caused by RM. Methods causes of RM, clinical manifestations, severity of disease evaluated by APACHE Ⅱ and Marshall MODS Score, results of laboratory, clinical interventions and outcome were analyzed in all three MODS cases secondary to RM. Results The specific causes of RM were not clear. However, persistent acute twitch and hyperthermia occurred very early in all three cases. Plasma CK was increased 50 fold over the normal level. Number of injured organs was 7, 4 and 6, respectively. Marshall MODS score ranged from 15 to 21. APACHE Ⅱ scores were greater than 20 in all cases. One patients survived, the other two died. CRRT started early had been shown to be beneficial to decrease the markedly elevated plasma CK, CK-Mb, ALT, ALT and LDH. Conclusion Although the mechanism of RM with secondary MODS has not been elucidated yet, deep sedation as well as effective hypothermia to control acute twitch and hyperthermia should be the essential interventions to attenuate further organ injury. Additionally, based on effective advanced life support, CRRT started early could be an important therapy for MODS secondary to RM.

Objective:To approach the effect of Naotangfang extracts on expression of vascular endothelial growth factor(VEGF) after focal cerebral infarct in rats. Methods:30 Sprague-Dawley(SD) rats were randomly divided into 6 groups:sham operation group,model group,Naotaifang extract groups(low,middle,and high dosage) ,and Naofukang group. Some indexes were detected such as neurological scores,VEGF mRNA expression by RT-PCR,and the number of VEGF positive cells by immunohistochemical methods. Results:The symptoms in nervous function were improved in the Admin. groups,especially in the Naotaifang middle dosage group. The number of VEGF positive cells and VEGF PCR production in Naotaifng middle dosage group was higher than that in the model group. Conclusion:Naotaifang has neuroprotective effect against focal cerebral ischemic injury by improving the expression of VEGF.

AIM: To investigate the effect of caveolin - 1 and phosphorylation of ERK1/2 on 17β - estradiol ( E_2 ) induced inhibition of vascular smooth muscle cells ( VSMCs ). METHODS: The proliferation in cultured VSMCs was determined by using [~3H ] - thymidine incorporation. The expressions of caveolin - 1, MKP -1 and ERK1/2 phosphorylation were measured by Western blotting. The expression of caveolin - 1 mRNA was measured by RT - PCR. RESULTS: Exposed to fetal calf serum ( FCS) for 24 h, the increase in proliferation of VSMCs was detected by [~3H] -thymidine incorporation. Pretreatment with various concentrations of E_2 for 24 h inhibited VSMC proliferation induced by FCS. The results of Western blotting and RT - PCR showed that pretreated with 17β - estradiol for 24 h reserved the decrease in caveolin - 1 induced by FCS. Western blotting results further proved that the expression of MKP - 1 was significantly increased and the expression of ERK1/2 phosphorylation was decreased after incubated with 17β - estradiol. CONCLUSION: 17β -estradiol increases caveolin - 1 and MKP - 1 expressions, and decreases ERK1/2 phosphorylation, leading to the inhibition of VSMC proliferation.

This systematic review was aimed to evaluation the effectiveness and safety of supplementingqi and activating blood circulation prescriptions in the treatment of cerebral ischemic stroke. Dtabases both at home and abroad were electronically searched for randomized controlled trials (RCTs) on supplementingqi and activating blood circulation prescriptions in the treatment of cerebral ischemic stroke. And meta-analyses were performed using RevMan 5.0 software. The results showed that 27 studies were included, which contained 2 908 cases. There were 1 490 cases in the treatment group, and 1 418 cases in the control group. The results of meta-analyses indicated that supplementingqi and activating blood circulation prescriptions combined with routine treatment of modern medicine had significant differences in the effective rate for cerebral ischemic stroke compared with the single using of routine treatment of modern medicine with significant difference (OR = 5.39, 95%CI (4.03, 7.22),P < 0.000 01). The treatment of supplementingqi and activating blood circulation prescriptions combined with routine treatment of modern medicine had better treatment effect on neurological function defects for cerebral ischemic stroke compared with the single using of routine treatment of modern medicine with significant difference (WMD = -2.99, 95%CI (-3.26, -2.72),P < 0.000 01). In addition, the treatment of supplementingqi and activating blood circulation prescriptions combined with routine treatment of modern medicine had better treatment effect on improving the activity of daily living (WMD = 9.65, 95%CI (8.36, 10.93),P < 0.000 01). Adverse reaction and event was mild in 2 included research reports. It was concluded that the treatment of supplementingqi and activating blood circulation prescription or it combined with routine treatment in modern medicine was quite effective in the treatment of cerebral ischemic stroke by the existed limited evidences. It can also improve the nerve dysfunction and the ability of daily living. Due to the limited quantity of the included studies and the evidence with limited strength, further high-quality RCTs were needed to verify the forementioned conclusion.

Objective To investigate the clinical effects and significance of different-dose atorvastatin on soluble CD105(sCD105),high sensitive-C reactive protein(hs-CRP)and the parameters of heart rate turbulence in patients with acute coronary syndrome(ACS). Methods One hundred and six ACS patients were divided into three groups by random digits table: control group(30 patients, routine treatment),treatment group Ⅰ(38 patients, routine treatment + atorvastatin 20 mg), and treatment group Ⅱ(38patients, routine treatment + atorvastatin 40 mg). All patients were treated for 4 weeks. The levels of serum sCD105,hs-CRP,and the parameters of heart rate turbulence before and after treatment. Results Before treatment, the levels of turbulence onset(TO), turbulence slope(TS),sCD105 and hs-CRP in three groups had no significant difference(P ＞ 0.05). After treatment, TO,sCD105 and hs-CRP decreased significantly,and TS increased significantly(P＜ 0.05 or ＜ 0.01). The change amplitude of treatment group Ⅱ was the most obvious, and the levels of above mentioned index showed significantly difference compared with that of treatment group Ⅰ[TO:(0.22 ±0.18)% vs.(0.66 ± 0.23)%;TS:(6.22 ±0.83)ms/RR interval(RRI)vs.(3.90 ±0.73)ms/RRI;sCD105:(1.65 ±0.43)mg/L vs.(2.92 ±0.50)mg/L;hs-CRP:(1.68 ±0.55)mg/L vs.(2.08±0.61)mg/L](P ＜0.01). Correlation analysis showed the levels of sCD105 and hs-CRP had significantly positive correlation with TO(P ＜ 0.01)and had negative correlation with TS(P ＜ 0.01).Conclusions The atorvastatin treatment in patients with ACS may stabilize coronary vascular endothelial cells and atherosclerotic plaque, and improve autonomic nerve function. Larger doses of atorvastatin may get more benefit.

Dioscin is the main ingredient of Dioscorea,a tradi-tional medical herb.Traditional theory of Chinese medicine be-lieves that Dioscorea has effects of clearing lung,digesting food, diuresis, improving blood circulation, relaxing muscles and stopping attack of malaria.Pharmacological studies have shown that dioscin has many pharmacological effects,particularly the anti-tumor effect.Many studies have also shown dioscin im-proves symptoms of atherosclerosis and protects blood vessel en-dothelium,reduces ischemia-reperfusion injury of heart,brain and kidney,lowers blood sugar,inhibits hepatic fibrosis,im-proves menopausal osteoporosis,relieves rheumatoid arthritis, ulcerative colitis and other inflammatory disorders,and posses-ses anti-bacterial and anti-viral activity.This article focuses on the progress of the modern pharmacological study of dioscin,and reports its advances in recent years.
