ABSTRACT

Objective Based on Chinese guidelines for the management of ischemic stroke, a standardized stroke management program was performed to provide intensive education and training for medical physicians, aiming to enhance their knowledge and ability for ischemic stroke prevention and treatment, thereby reducing patients′ in-hospital cost and length of stay, and improving patients′ clinical prognosis. Methods This study was conducted in 20 general hospitals throughout Hainan province. A total of 163 physicians from 20 hospitals involved in the management of stroke patients were trained by highly experienced physicians based on the Chinese guidelines for diagnosis and treatment of acute ischemic stroke 2014 and the Chinese guidelines for secondary prevention of ischemic stroke and transient ischemic attack 2014. Prior to and post the standardized stroke management training, the data of 3218 and 3367 patients with ischemic stroke were respectively collected. Quality of life assessments including the Barthel index (BI) and the modified Rankin Scale (mRS) score of all patients were recorded at baseline and after discharge. The length of stay and in-hospital cost were directly collected from the hospital information system. Results Physicians′ knowledge and ability manifested as testing scores were significantly improved after training (78.2 ± 15.5 vs 55.6 ± 10.7, t=69.1, P<0.01). The average length of stay of post-training patients was significantly shorter than that of pre-training patients ((8.7 ± 0.9) vs (11.7 ± 1.5) days, t=97.9, P<0.01). The average in-hospital cost of post-training patients was significantly less than that of pre-training patients ((7681.7 ± 1397.7) vs (11846.2 ± 2514.6) Yuan, t=82.5, P<0.01). Both BI (68.2 ± 3.2 vs 43.5 ± 5.3, t=227.7, P<0.01) and mRS score (2.74±0.51 vs 3.65±0.71, t=59.5, P<0.01) were significantly improved for post-training patients. Multivariate linear regression analysis illustrated that standardized stroke management was negatively associated with in-hospital cost (r=-0.461, P<0.01), length of stay (r=-0.357, P<0.01) and mRS score (r=-0.298, P<0.01), and was positively associated with levels of BI (r=0.376, P<0.01). Conclusion Standardized stroke management program might be a cost-effective choice for the management of ischemic stroke as it reduces the in-hospital cost and improves patients′BI and mRS levels.

ABSTRACT

Aim Fuzhisan ( FZS ) , a Chinese herbal complex prescription that has been used for the treat-ment of AD for over 15 years, is known to enhance the cognitive ability in AD patients. In this study, to in-vestigate whether FZS reduces Aβ25-35-induced Tau protein hyperphosphorylation in neonatal rat cortical neurons by suppressing the cyclin-dependent kinase 5 ( CDK5 ) pathway. Methods Neonatal Wistar rats born within 24 h were selected to separate and purify their cortical neurons for culture in vitro. After 7-day culture of cortical neurons in vitro, 20 μmol · L-1 Aβ25-35 was used to act on them for 24 h. Medication groups were pretreated with FZS ( 20 mg · L-1 ) , CDK5 inhibitor roscovitine ( 15 μmol · L-1 ) and cal-pain preparation calpeptin (20 μmol·L-1 ) for 24 h, followed by reaction with 20 μmol·L-1 Aβ25-35 for 24 h. Tau protein phosphorylation levels at Ser396, Ser202 and Thr231 and the protein level of CDK5 acti-vator proteins p25/p35 were assayed by Western blot. Fluorescence intensity was measured with a fluores-cence microplate reader to reflect calpain activity. CDK5 kinase activity was assayed by immunoprecipita-tion. Results After 20 μmol·L-1 Aβ25-35 acting on cortical neurons for 24h, there were increments in the following: Tau protein phosphorylation levels at Ser396, Ser202 and Thr231, CDK5 kinase activity, CDK5 activator protein p25 level, and calpain activity. In the 20 mg·L-1 FZS treatment group, Aβ25-35 was suppressed markedly, resulting in increments in Tau protein phosphorylation levels at Ser396 , Ser202 and Thr231 , suppression of CDK5 kinase activity and p25 protein level, and elevation in calpain activity. Both CDK5 inhibitor roscovitine and calpain preparation cal-peptin, as positive control drugs, also played a role in suppressing Tau protein hyperphosphorylation. Con-clusion FZS can suppress Aβ25-35-induced Tau pro-tein hyperphosphorylation in cortical neurons through the calpain/CDK5 pathway.

ABSTRACT

Objective To study the effect of S-adenomethionine on early stage recovery of transplanted liver.Methods From January 2010 to October 2012,57 liver transplantation patients were divided into 2 groups beginning the first day:group A,23 patients were treated with routine liver-protecting therapy,including glycyrrhizin,glutathione,albumin; group B,34 patients treated with additional S-adenomethionine (Transmetil).AST,ALT,T-BIL,D-BIL,γ-GT,ALB and ALP were compared between the two groups at pre-operation and post-operation day 1,day 4,day 7 and day 14.Results All patients suffered from preoperative hyperbilirubinemia,decreased ALB and elevated concentration of AST,ALT,γ-GT and ALP.On the first day after transplant,AST,ALT,T-BIL,D-BIL and γ-GT elevated and ALB decreased significantly in all cases compared with that before operation (respectively t =10.493,7.089,6.584,15.134,5.164,10.344,5.289,13.034,3.389,4.366,all P < 0.01).On the contrary,the value of ALB was lower (respectively t =8.239,11.662,all P < 0.05).On the fourth day posttransplant,ALB level was higher and that of other parameters were lower in group B when compared with group A (respectively t =2.536,2.736,2.218,3.318,4.804,2.892,all P < O.05).This tendency of liver function improvement continued till postoperative day 7 in all cases while the differences between the two groups remained significant (respectively t =6.107,3.256,2.929,11.688,8.964,2.857,all P < 0.05)except for γ-GT.On day 14,while T-BIL and D-BIL in group B were lower than that in group A (respectively t =4.413,8.493,all P <0.001),differences of liver functions were not significant between the two groups (respectively t =1.916,1.414,1.168,1.035,1.604,all P > 0.05).Conclusions Transmetil promotes the recovery of transplanted liver's function,elevates the concentrantion of ALB and reduces the concentration of AST,ALT,T-BIL,D-BIL,γ-GT and ALP at early stage after liver transplant.

ABSTRACT

Objective To detect the expression of miR-10b in hepatocellular carcinoma (HCC) tissue samples,and to explore its association with clinicopathologic features.Methods qRT-PCR analysis was used to detect expression of miR-10b in 58 HCC tissues (Among them,32 cases were diagnosed with metastasis by pathological analysis,26 cases without metastases at the time of resection) and 10 normal liver tissues.Statistical analysis was used to determine the association of miR-10b expression with clinicopathologic features and prognosis of patients.Results miR-10b was up-regulated both in metastasis-free and metastatic HCC tissues,but its up-regulated degree was much more significant in metastatic HCC tissues (P<0.05).High miR-10b expression was strongly correlated with the metastasis (P<0.01) and AJCC stage(P=0.016).But it was not correlated with age,gender,hepatitis B,cirrhosis,tumor size,degree of differentiation,and tumor number.Patients with high miR-10b expression had significantly poorer overall survival(P<0.01).High miR-10b expression was independent prognostic factors for overall survival (P=0.016).Conclusions The expression of miR-10b is highly up-regulated in HCC tissues,especially in metastatic HCC tissues,indicating that high miR-10b expression may be involved in the process of metastasis and is expected to become a new prognosis reference of HCC.

Forty five patients with acute cerebral infarction were randomized to two groups: in treatment group patients received local subhypothermia and conventional therapy, in control group patients received conventional therapy only. Clinical outcome was assessed by the National Institutes of Health Stroke Scale (NIHSS) on admission and at 7, 14 and 30 d after treatment. Serum neuron specific enolase (NSE), nitrogen monoxide ( NO ) , superoxide dismutase (SOD), interleukin-6 (IL-6 ) and intercellular adhesion molecule-1 (ICAM-1) were detected on admission and at 7,14 d after treatment The study showed that NIHSS scores of treatment group on 14, 30 d were lower than those of control group ( P < 0. 05 ). Serum NSE, NO, IL-6 and ICAM-1 levels significantly decrease; while serum SOD levels increased (P < 0. 05). In conclusion, local subhypothermia therapy can inhibit inflammatory reaction, reduce oxygen free radical formation and improve neurological function in patients with acute cerebral infarction.

ABSTRACT

OBJECTIVE@#To discuss the application of anatomization of the recurrent laryngeal nerve under the microscope in thyroid surgery.@*METHOD@#292 patients with different types of thyroid diseases who underwent surgical intervention were discussed by regression analysis. For all patients, the movement of both vocal cords was normal before the surgery by laryngoscope. And routine anatomization of the recurrent laryngeal nerve under the microscope was conducted during thyroid surgery.@*RESULT@#The total number of recurrent laryngeal nerve exposure in this study was 402. Only three of them got temporary injury. None had permanent damage.@*CONCLUSION@#The recurrent laryngeal nerve can be visualized more clearly by dissection under the microscope, which can best avoid the recurrent laryngeal nerve injury. Particularly it is beneficial for the patients who have prior thyroid surgery history or have thyroid gland cancer.

ABSTRACT

Objective To construct a RhoA-siRNA expression vector and determine its role on the malig-nant behavior of HepG2 cells.Methods A RhoA-siRNA DNA fragment was synthesized and cloned into the expression vector of pGenesil-1.The constructed Rhon-siRNA DNA plasmid was stably transfected into HerG2 cells by lipofectamine,and then HepG2 cells were divided into the HepG2/RhoA-siRNA group (HepG2 cells were transfected with pGenesil-1-RhoA-siRNA),HepG2/control group(HepG2 cells were transfected with control plasmid) and HepG2 group (without plasmid transfection).The inbibitory effect of RhoA-siRNA on RhoA protein expression was shown by Western blot.The proliferation,migration,growth potentiality and cell cycle of transfected HepG2 cells were evaluated by MTT assay,wounded healing,the plate cloning formation test and flow cytometry,respectively.All data were analyzed by one-way analysis of variance (ANOVA) and chi-square test.Results The expression of RhoA protein in the HepG2/RhoA-siRNA group was,significantly decreased compared with that in the other two groups (F=178.19,P<0.05).Scratched cells were healed within 48 hours in the HepG2/control group and HepG2 group,but not in the HepG2/RhoA-siRNA group.The clone formation rates in the HepG2/RhoA-siRNA group,HepG2 group and HepG2/control group were 39%±3%,67%±5%and 70%±6%,respectively,with a significant difference among the three groups(χ2=33.34,38.69,P<0.05).Flow cytometry showed that the number of cells transfected with RhoA-siRNA was highest in the G0/G1 phase and lowest in the S phase(F=70.46,76.57.P<0.05).Conclusion The RhoA-siRNA expression vector can effectively suppress the proliferation and migration of HepG2 cells,which may provide a novel gene therapy for hepatocellular carcinoma.

ABSTRACT

The incidence of warfarin-associated intracerebral hemorrhage is increasing gradually. Its early mortality is as high as 50%. The risk factors include advanced age, international normalized ratio > 3.5, hypertension, previous stroke, leukoaraiosis, cerebral amyloid angiopathy, and concomitant antiplatelet therapy, etc. Its prognosis was poor and there is no optimal treatment.

ABSTRACT

Prasugrel is a member of the thienopyridine class of oral antiplatelet agents.A single oral administration of prasugrel produced a dose-related inhibition of platelet aggrega-tion in rats that was approximately 10 and 100 fold more potent than that of clopidogrel and ticiopidine, respectively. The antiaggregatory effect of prasugrei was evident at 30 minutes and lasted until 72 hours after dosing, indicating fast onset and long duration of action. Combined administration of prasugrel with aspirin produced substantially greater inhibition of both platelet aggregation and thrombus formation compared with each agent alone. Clinical studies in patients with cardiovascular disease confirmed the potent antiplatelet effect of prasugrel compared with ciopidogrel. Prasugrei is a highly effective antiplatelet and antithrombotic agent and is anticipa-ted to be effective in the treatment of atherothrombotic and other ischemic vascular diseases.

ABSTRACT

Objective To investigate the expression of RhoA gene in human hepatocellular carcinoma (HCC) and to discuss its significance during hepatocellular carcinogenesis. Methods Intratumor RhoA expression level was determined and compared with that in adjacent nontumorous hepatic tissues using quantitative real time reverse transcription polymerase chain reaction and Western blot in 64 HCC patients. Results The mRNA levels of RhoA were significantly higher in tumor tissues than that in the unaffected portions (t =3.445 ,P =0.0006). The expression of RhoA mRNA in the primary lesion was higher in patients with venous invasion (t = 2.667, P = 0.009), microscopic satellite lesions (t=2.172,P =0.038), and advanced pTNM stage (stage Ⅱ/Ⅳ; t=2.551,P=0.013) than in those without. There was a significant difference between high RhoA protein levels in the tumor tissues and noncancerous liver tissues in HCC patients (t = 3.532, P = 0.0002), and there was a significant association between high tumor RhoA protein levels and the presence of venous invasion (t = 2.087, P = 0.042), microscopic satellite lesions (t = 2.254, P = 0.031), and advanced pTNM stage (t = 2.812, P = 0.007). Conclusions There is a significant correlation between RhoA expression, tumor stage, and intrahepatic metastasis. The expression of RhoA could be used as a good tumor marker for invasive and advanced carcinoma as well as a prognosis predictor.
