Objective To analyze and compare the clinical effects of comprehensive treatment and liver transplantation for hepatocellular carcinomas (HCC)exceeding Milan criteria.Methods A retrospective analysis was performed on the clinical data of 157 patients with HCC (exceeding Milan criteria)who received comprehensive treatment (99 patients,including 48 cases meeting Shanghai criteria)and liv-er transplantation (58 patients,including 26 cases meeting Shanghai criteria)in our hospital from January 2006 to January 2010.The medi-an survival times and 1 -,2-,and 3-year survival rates were calculated by the Kaplan-Meier method,and the log-rank test was used for survival difference analysis.Results For all patients,the median survival times of the comprehensive treatment group and liver trans-plantation group were 18.00 ±1.15 and 23.40 ±4.44 months,respectively,and their 3 -year survival rates were(18.2 ±3.9)% and (39.7 ±6.4)%,respectively;the survival was significantly improved by the treatment of liver transplantation (P=0.009).For patients meeting Shanghai criteria,the median survival times of the comprehensive treatment group and liver transplantation group were 20.00 ±1.17 and 36.00 ±0.00 months,respectively,and their 3-year survival rates were (25.0 ±6.3)% and (57.7 ±9.7)%,respectively;there was significant survival difference between the two groups (P=0.008).For patients exceeding Shanghai criteria,the median survival times of the comprehensive treatment group and liver transplantation group were 16.00 ±1.78 and 16.00 ±1.69 months,respectively,and their 3-year survival rates were (11.8 ±4.5)% and (25.0 ±7.7)%,respectively;there was no significant survival difference between the two groups (P=0.221).Conclusion Compared with comprehensive treatment,liver transplantation leads to a significant higher long-term survival rate in HCC patients exceeding Milan criteria but meeting Shanghai criteria.However,the two therapies cause no significant survival difference in HCC patients exceeding Shanghai criteria.

ObjectiveTo investigate the role of electroencephalogram (EEG) examination in the prognosis evaluation of patients with severe craniocerebral injury.MethodsFifty-seven patients with severe craniocerebral injury were selected as study subjects and their clinical data were analyzed retrospectively.All the patients got EEG examination,and the relationships between EEG grading and Glasgow coma scale (GCS) score,the prognosis of outcome were analyzed.ResultsThe EEG of 57 patients within 24 h after hospitalization were all abnormal.There was significantly negative correlation between EEG grading and GCS score (r =-0.742,P ＜0.05).EEG grading was significantly positively correlated with the prognosis of outcome (r =0.730,P＜ 0.05).ConclusionsEEG examination and EEG grading can evaluate the prognosis of patients with severe craniocerebral injury.It provides reference for clinical treatments.

Objective To explore the risk factors of hyponatremia in postoperative patients with aneurysm and analyze the clinical characterstics in order to provide reference for clinic.Methods Participants included 120 patients who treated by aneurysm occlusion.Detailed recorded the patient's history and basic information.The patients with hyponatremia were in case group,and other patients were in control group.The risk factors of hyponatremia were analyzed.Results Forty-five patients (37.5％) occurred hyponatremia after operation.The level of natrium was (125.2 ± 10.1) mmol/L,the average time of appear hyponatremia was (8.2 ± 0.8) d,15 patients were in the first peak(postoperative 1-3 d),25 patients were in the second peak (postoperative 8-9 d),5 patients occurred hyponatremia at other time.Thirty-nine patients were internal carotid artery aneurysms,6 patients were vertebrobasilar artery aneurysms.Single factor analysis showed that the age,preoperative GCS scores,history of hypertension and diabetes,emergency operation,the size of arterial aneurysms,medium-sized aneurysm of artery between two groups had significant difference [(48.7 ± 8.4) years vs.(54.7 ± 8.4) years,(14.4 ± 3.1) scores vs.(10.3 ± 3.4)scores,26.7％ (20/75) vs.60.0％ (27/45),33.3％ (25/75) vs.62.2％ (28/45),32.0％ (24/75) vs.62.2％(28/45),(0.9 ±0.3) cm vs.(1.4 ±0.4) cm,24.0％(18/75) vs.42.2％(19/45),P ＜ 0.01 or ＜ 0.05].Multifactors regression analysis showed that preoperative GCS scores,emergency operation were the independent risk factors of hyponatremia (P＜ 0.05).Conclusions Postoperative 1-3 d and 8-9 d are the peak stage of hyponatremia.Different treatment should be adopted according the peak stage.Lower scores of preoperative GCS and emergency operation are the independent risk factors of hyponatremia.Clinical work need to pay more attention to the risk factors,appropriate treatment and prevention.

Objective To investigate the influence of different interventional treatment timing on the prognosis of patients with intracranial aneurysms. Methods One hundred and thirty-eight patients with ruptured intracranial aneurysms were divided into group A (Ⅰ- Ⅲ grade) with 109 cases and group B ( Ⅳ- Ⅴ grade) with 29 cases according to Hunt-Hess grade when admitted. All patients received interventional treatment, the operation period was divided into early, middle and late stage according to the different time from disease time to operation, then compared the good rate, cerebral vasospasm and hydrocephalus incidence of patients underwent surgery at different period. Results The good rate at different period in group A were respectively 69.7% (23/33),58.8% (10/17) and 61.0% (36/59),which and the cerebral vasospasm and hydrocephalus incidence of patients underwent surgery at different period in group A had no significant difference(P > 0.05). The good rate of patients received surgical treatment at early stage in group B was 46.2%(6/13), which was significantly superior to late stage (0), the difference was statistically significant (P < 0.05), while the cerebral vasospasm and hydrocephalus incidence of patients underwent surgery at different period in group B had no significant difference(P> 0.05). Conclusion The prognosis of patients with Hunt-Hess grade Ⅰ - Ⅲ grade undergoing interventional treatment at early, middle and late stage can be satisfactory, while grade Ⅳ - Ⅴ grade patients should receive interventional treatment at early stage.

Objective To study the genetic diversity of Fritillaria thunbergii,a traditional Chinese herb in Zhejiang Province in China.Methods The genetic diversity of six representational populations of F.thunbergii including 32 individuals was investigated by amplified fragment length polymorphism(AFLP) maker technique.Results The genetic diversity was revealed as follow: the Nei′s genetic diversity index(He) 0.169 0?0.175 7,Shannon′s information index(I) 0.269 8?0.245 3,percentage of polymorphic loci(PPB) was 76.85% at the species level;Ht 0.169 0?0.030 9,and Hs 0.150 8?0.024 0,I 0.233 3?0.261 9, PPB was 50.38% at population level.The genetic differentiation index(Gst) was 0.107 6,Nm 4.147 0.The result of dendrogram of six populations indicated that Dongyang and Yongkang populations shared the minimum genetic distance(0.015 0),they were classified into a group,and Xiangshan and Jinyun populations shared the maximum genetic distance(0.032 4).Conclusion The genetic diversity of F.thunbergii cultivated in Zhejiang Province is very rich,which could ensure the long-term survival of F.thunbergii.But the genetic diversity of F.thunbergii is relatively higher in population levels while lower at the species levels and the degree of genetic differentiation occured among the populations is not significant.The germplasm resources are relatively stable among these six populations.These populations could be used to breed the fine strains of F.thunbergii as the bases.

Objective To observe the genetic structure of cultivated Scrophularia ningpoensis in Zhejiang Province.Methods The genetic structures of six typical S.ningpoensis populations were analyzed by fluorescence AFLP marker.Results Bands(12 552) were generated by seven pairs of AFLP primer combinations,of which 8 808 were polymorphic,and the polymorphic rate was 70.17%.The variety ranges of PPB among different populations were 41.67%—55.56%,and 47.30% in average.I was between 0.190 8—0.238 3,and 0.221 8 in average.Ne was between 1.201 4—1.280 6,and 1.236 9 in average.Gst was 0.127 1,Nm was 3.432 4.UPGMA Cluster analysis showed that the six populations can be divided into two clusters,as that of Tiantai,Jinyun,and Jingning were one sub-cluster,and Dongyang,Pan′an,and Xianju were another one sub-cluster.Conclusion There is a relative high genetic diversity level in cultured S.ningpoensis of Zhejiang Province.Genetic differentiation exists among populations,but it exists in population mostly.There is a relative high genetic intercommunion among populations.The genetic distance is not related to the geographic environment.

Objective To investigate the dynamical changes of Rho kinase in the cerebrospinal fluid (CSF) and its relationship with cerebral vascular spasm CVS. Methods CSF were collected on the ist, 3rd, 7th, 10th and 14th day after subarachnoid hemorrhage. The expression of Rho-kinase mRNA in CSF was determined by RT-PCR. The expression of endothelin-1 in CSF was determined by radioimmuno-assay. TCD was used to measure the velocity of the cerebral artery. Results The levels of ET-1 and Rho-kinase mRNA in CSF were re-markably increased on the 3rd day, and reached at the peak on the 7th day after subarachnoid hemorrhage, which were significantly higher than those without CVS. Conclusion There is a positive correlation between the level of Rho-kinase mRNA and ET-1 in CSF. Rho-kinase may participate in the development of CVS.

BACKGROUND:There are less studies addressing whether bone marrow mesenchymal stem cells from systemic lupus erythematosus patients are different from healthy people.
OBJECTIVE:To compare the multi-differentiation capacity of bone marrow mesenchymal stem cells isolated from systemic lupus erythematosus model mice and normal control mice.
METHODS:Bone marrow mesenchymal stem cells of systemic lupus erythematosus model mice and C57BL mice were isolated and cultured fol owed by osteogenic and adipogenic differentiations, respectively. Differentiation abilities of two kinds of mouse bone marrow mesenchymal stem cells were observed.
RESULTS AND CONCLUSION:Passaged bone marrow mesenchymal stem cells from C57BL mice were long spindle-shaped and evenly distributed, while bone marrow mesenchymal stem cells from systemic lupus erythematosus model mice showed slow growth and were relatively smal er than those from C57BL mice. After osteogenic induction, the amount of calcium salt and calcium nodules were significantly less in the bone marrow mesenchymal stem cells from systemic lupus erythematosus model mice than from normal control mice. PCR detection showed that expressions of Runx2, alkaline phosphatase and osteocalcin were also significantly decreased in the bone marrow mesenchymal stem cells from systemic lupus erythematosus model mice. After adipogenic induction, the number of lipid droplets in the bone marrow mesenchymal stem cells from systemic lupus erythematosus model mice was significantly less than the control group, and PCR detection also showed significantly decreased expression of adipogenic genes, including PPARγ2 and lipoprotein lipase. These findings suggest that the bone marrow mesenchymal stem cells from systemic lupus erythematosus model mice exhibit lower osteogenic and adipogenic capacities than those from normal C57BL mice, and also have the impaired multi-differentiation ability.

Objective To analyze the early renal function of donors after nephrectomy.Methods Clinical data of 467 cases of living kidney donors during the period from April,2010 and November,2014 in our center were retrospectively analyzed.Data on serum creatinine (Scr),glomerular filtration rate (GFR),serum uric acid (UA),and urine microproteins before operation and three days,seven days,one month and three months after operation were collected to evaluate the impact of nephrectomy on early renal function after operation for donators.Results Before operation and three days,seven days,one month,three months after operation,the average serum creatinine (Scr) level was (59.9±12.8),(85.8±21.0),(91.2±21.3),(92.8±21.6),(91.0±21.3) μmol/L,respectively; The GFR were (113.5±25.3),(75.1± 17.9),(70.3± 15.2),(68.5± 16.0),(69.5± 15.1) ml/min,respectively; The levels of uric acid were (292.60±79.58),(142.18±55.28),(228.41±66.39),(321.31± 83.72),(346.61±87.21) μmol/L,respectively; All these data above-mentioned after operation reached statistical significance compared with that before operation (P ＜ 0.05).Parameters including urine IgG,urine albumin,urine retinol-binding protein and urine β2-microglobulin post-operation time point were significantly different when compared with relative parameters pre-operation (P ＜ 0.05).Conclusions Nephrectomy has significant influence on GFR,uric acid,and urine microprotein for donors in the early stage after operation.It's worth to evaluate nephrectomy's long-term effect on the renal function of donors in clinical practice.
