Objective To study the effect of Simiaoyongantang on human umbilical vein endothelial cells(HUVECs) injury induced by hypoxia.Methods The HUVECs were divided into normal group,model group and Simiaoyongantang group,and the hypoxia model was established at the latter two groups.The livability of HUVECs was measured by MTT assay.The transudation of LDH in the medium was measured by biochemistry and the positive expression of VEGF was detected by immunofuorescence chemistry.Results The level of LDH was reduced significantly and the cell activity indicated by MTT was increased.The number of the cells stained by VEGF increased in the treatment group of Simiaoyongantang.Conclution Simiaoyongantang has protective effect on hypoxia injured HUVECs,which may be related to its effect of increasing the cells livability,reducing the injury induced by hypoxia,up-regulating expressions of VEGF and promoting angiogenesis.

Objectives To examine clinical characteristics,predisposing factors,treatment and care of depression and/or anxiety symptoms in hospitalized patients with cardiovascular diseases.Methods A retrospective analysis of clinical data of 1 005 hospitalized patients with cardiovascular diseases at our hospital from January 2015 to December 2015 was conducted and psychological assessment for all patients was carried out using the Hamilton Anxiety Rating Scale and the Hamilton Depression Rating Scale.The incidence of depression and anxiety and predisposing factors were investigated.The effectiveness of psychological intervention in addition to cardiovascular medications was evaluated.Results The overall incidence of depression and anxiety was 23.4％ (235 cases) among the 1 005 hospitalized patients with cardiovascular diseases.Of the 235 cases,73 cases(31.1％) had anxiety,33 cases had depression (14.0％),and 129 cases had both anxiety and depression (54.9％).The occurrence of anxiety was significantly higher than that of depression(P＜0.05).Risk factors for anxiety and depression in patients with cardiovascular diseases included work-related fatigue,working conditions and health status.The rate of effectiveness of psychological intervention was 95.4％,and no serious adverse events were observed.Conclusions Depression and anxiety are common in hospitalized cardiovascular patients and can be attributed to factors such as work-related fatigue,working conditions and health status.Favorable clinical outcomes can be achieved through psychological interventions,in addition to cardiovascular drug therapy.

BACKGROUND:Osteofascial compartment syndrome is usual y due to application of external fixation for fracture treatment. Vaseline gauze is used to cover and compress the wound. Frequent dressing change induces infection and is harmful to wound drainage and tissue granulation, final y causing prolonged time of hospitalization and bad results. ＜br> OBJECTIVE:To investigate the clinical efficacy of Ilizarov external fixation combined with vacuum sealing drainage treatment for limb fractures with osteofascial compartment syndrome. ＜br> METHODS:A total of 32 patients with limb fractures with osteofascial compartment syndrome were randomly divided into two groups. Al patients adopted the same fasciotomy and drug treatment. In treatment group, the fracture was fixed with Ilizarov external fixation and the wound was covered with the vacuum sealing drainage dressing. In control group, the fractures were treated by unilateral external fixation and the wound was covered with the vaseline gauze. The fracture healing, clinical effects, hospitalization duration and costs between two groups were compared. ＜br> RESULTS AND CONCLUSION:In the treatment group, there were 10 cases of healing wel , 4 cases of muscle contracture and 2 cases of amputation. In the control group, there were 7 cases of healing wel , 6 cases of muscle contracture and 3 cases of amputation. No significant difference in clinical outcome measures was detected between the two groups. Fracture healing rate and costs were higher in the treatment group than in the control group (P＜0.05), but hospitalization duration, skin grafts and the incidence of infection were lower in the treatment group than in the control group (P＜0.05). Results suggested that on the basis of timely fasciotomy and decompression, Ilizarov external fixation combined with vacuum sealing drainage treatment for limb fractures with osteofascial compartment syndrome has a high limb salvage rate, which can effectively treat fractures, elevate the healing rate of fractures, reduce infection rate and skin grafting rate, shorten hospital stays. However, the hospitalization expense is higher.

Objective To investigate the relation between the expression of toll receptor-4 (TLR-4) and the increase of blood brain barrier (BBB) permeability in the rats with acute pancreatitis.Methods Male Sprague-Dawley rats were randomly divided into 8 groups:control group;acute edematous pancreatitis (AEP) 2 h,6 h groups;acute necrotizing pancreatitis (ANP) 2 h,6 h,12 h,24 h,48 h groups with 8 rats in each group.The BBB permeability,pathological score of pancreas,TLR-4 expression were determined and the relationships between them were analyzed.Results The BBB permeability in control group;acute edematous pancreatitis (AEP) 2 h,6 h groups;ANP 2 h,6 h,12 h,24 h,48 h groups were 1.55±0.29,1.64±0.17,1.69±0.24,1.89±0.12,2.66±0.32,2.91±0.29,2.89±0.69 and 1.84±0.07,respectively;the pathological scores of pancreas were 0,2.38±0.92,3.13±0.64,8.50±1.07,9.75±0.71,10.25±1.28,11.13±1.25 and 10.13±1.13,respectively;there was no significant difference between AEP groups and control group,while there was significant difference between AEP groups and ANP groups (P＜0.05 orP ＜0.01).BBB permeability was correlated with pancreatic injury ( r = 0.626,P ＜0.01).There was no TLR-4 mRNA and protein expression in the control and AEP group,while they were significantly expressed in ANP groups,and the expression were positively related with BBB permeability ( r =0.208,P = 0.027 ).Conclusions BBB permeability was present in the course of ANP.Activation of TLR-4 signal pathway may be involved in the BBB permeability increase caused by ANP.

BACKGROUND: Surface roughness of implants can directly influence cellular proliferation, differentiation, and gene expression. OBJECTIVE: To observe the early attachment of periodontal ligament cells (PDLCs) to pure titanium with different surface roughness levels, and to study the effect of surface performance on cell differentiation. DESIGN, TIME AND SETTING: Randomized controlled observation/multi-sample comparison study, which was performed at Center of Science and Technology, Gannan Medical College between January 2005 and July 2006. MATERIALS: Pure titanium stick was cut into pieces, of 10 mm diameter and 2 mm thickness, using cutting-off machine, and there were 24 sections in total. Then, the titanium sections were randomly divided into four groups: simple mechanical processing, nitric acid processing, sand blasting processing, and combination group, with 6 sections per group. METHODS: TR240 portable-type surface roughness meter was used in this study. In the simple mechanical processing group, sections were scoured by sand paper alone; in the nitric acid processing group, sections were etched with 65% HNO3 for 1 hour at 100 ℃ after scoured by sand paper; in the sand blasting processing group, sections were sandblasted by 100 μ m AI203 after scoured by sand paper; in the combination group, sections were etched with 65% HNO3 for I hour at 100～C after scoured by sand paper and sandblasted by 100 μ m Al2O3. MAIN OUTCOME MEASURES: Samples were maintained in DMEM for 30 minutes, and the third-passage cells were inoculated. Then, titanium sections were taken out at different time points of 30, 60, 120, 240 minutes, 1, 3, and 7 days. Surface roughness and early attachment of PDLCs were detected under fluorescent microscope. RESULTS: O Quantitative analysis: Surface roughness was (599.5±8.3) nm in the simple mechanical processing group, (406.5 +4.6) nm in the nitric acid processing group, (358.8±11.8) nm in the sand blasting processing group, and (8.7±2.0) nm in the combination group. On the other hand, surface roughness in the simple mechanical processing group was significantly higher Fluorescence observation exhibited that number of PDLCs attaching to pure titanium surface was increased, and the proliferation was greater with the time passing by. in addition, surface roughness of pure titanium was positively associated with number of PDLCs. CONCLUSION: The lighter the surface roughness is, the more the early attachment of PDLCs is, benefiting for cell adhesion and proliferation.

ObjectiveTo investigate the effects of chitosan/PVA nerve conduits which used for repairing sciatics nerve defect in rats.MethodsTwenty-seven rats were divided into 3 groups randomly,with 9 rats in each group. Firstly, the 15mm defects in the left sciatic nerves were made in the rats and were respectively repaired with chitosan/PVA conduits graft (group A), the silicon conduits graft (group B),and autografts (group C). At 12 weeks after the operations, the left sciatic nerves were taken out, and the comparative evaluation was made on the repairing effects by wet weight of gastrocnemius and soleus muscles, histological examination,computerized imaging analysis and True Blue retrograde tracing. ResultsThe wet weight of gastrocnemius and soleus muscles showed no significant difference between the chitosan/PVA graft and autograft groups (P ＞ 0.05). The wet weight of gastrocnemius and soleus muscles in significant difference between the chitosan/PVA graft and the silicon group at 12 weeks after the operation(P ＜ 0.05). The nerve fiber density showed no statistically significant differences between the chitosan/PVA and autograft groups(P＞ 0.05).The regenerative nerve fiber in group B had normal morphological and structural characters under transmission electron microscope.True Blue-labeled neuron cell bodies were found within both anterior horn of gray matter in the spinal cord and dorsal root ganglions (DRGs) ipsilateral to the operated side of the tested rats on illumination with ultra-violet light 1 week after the injection of True Blue.Conclusion Chitosan/PVA nerve conduit can effectively promote the nerve regeneration and myelinization of rat sciatic nerve, which is expected to substitute for autograft to repair nerve defects succesfully.
