1.Improved methods of establishing rabbit VX2 hepatocarcinoma models
Chinese Journal of Tissue Engineering Research 2015;(27):4361-4364
BACKGROUND:Rabbit VX2 hepatocarcinoma models are characterized by expanded and infiltrative growth, abundant blood supply, similar pathological and imaging features to human hepatocelular carcinoma, so this model is ideal for imaging experiments. OBJECTIVE: To establish rabbit VX2 hepatocarcinoma models and compare two different laparotomy methods in establishing rabbit VX2 hepatocarcinoma models. METHODS:Thirty New Zealand rabbits were randomly divided into two groups: traditional laparotomy (tumor particles were directly embedded into the liver with tweezers) and improved laparotomy (tumor particles were injected into the liver through a 15G syringe needle). The growth features of the tumor established in two different ways were compared by ultrasound. RESULTS AND CONCLUSION:The tumor formation rate was 100% in the two groups; the single rate was respectively 50% and 90%; the ectopic implantation rate was 50% and 10%, there were significant differences between two groups (P < 0.05). The mortality rate within 2 weeks was 33% and 0 in the two groups, with significant differences (P < 0.05). The improved laparotomy method is feasible for modeling rabbit VX2 hepatocarcinoma, due to minimal injury, short operation time, high success rate and stable features.

Objective To economically investigate tertiary stroke rehabilitation treatment.Methods 3 tertiary rehabilitation networks were set up in Beijing.82 patients with acute cerebrovascular diseases were enrolled into the study according to standardized criteria in all centers and randomized into rehabilitation group and control group.Rehabilitation training was implemented according to standardized procedures.The patients in rehabilitation group were given rehabilitation training in acute stage for 28 days and then underwent long term rehabilitation'program for 6 months in rehabilitation centers or community rehabilitation settings.The patients in control group were only given rehabilitation training in acute stage for 28 days. Altogether 4 evaluations were conducted in one week after the onset and at the end of 1,3,6 months, respectively.Results Significant differences of motor function,ability of daily activities,quality of life evaluation and cost were found in the 1st,3rd and 6th month after the onset of diseases.The rehabilitation group surpassed the control group significantly.At the end of 6 months,the average of Barthel Index of rehabilitation group was 83.18?18.22 while that of control group was 63.69?12.73.At the end of 6 months,total cost of rehabilitation group was(56 420.0?17 831.8)Yuan and that of control group was (64 864.2?18 267.5)Yuan.The rehabilitation group had better cost/effectiveness and cost/utility.There was a significant difference of cost between two groups.The total rehabilitation cost of rehabilitation group was 4613 Yuan,accounting for 15.3%of all the cost.Conclusion The tertiary rehabilitation treatment for stroke patients has achieved better cost/effectiveness and cost/utility.In China pharmaceutical cost constitutes the major part of the stroke therapy while the rehabilitation cost only a small portion,which is significantly different from the situation in developed countries.

Background:Gastric cancer is a common gastrointestinal malignancy. The detection rate of early gastric cancer is still low in China,and some gastric cancer patients visit the hospital due to acute disease,such as gastric perforation. Aims:To investigate the influence of acute disease on long-term prognosis in gastric cancer patients. Methods:A total of 318 patients with gastric cancer from Jan. 2009 to Jan. 2015 at Shaoxing People’s Hospital were enrolled,and were divided into acute disease group and non-acute disease group. Clinicopathological characteristics were analyzed. Patients were followed up,and survival rate was compared between the two groups. Results:Fifty-three(16. 7% )patients had acute disease,and the remaining 265(83. 3% )patients were without acute disease. Compared with non-acute disease group, percentage of TNM Ⅳ stage was significantly increased(P < 0. 05),and percentage of radical surgery was significantly decreased in acute disease group(P < 0. 05). Kaplan-Meier assay showed that survival rate in acute disease group was significantly decreased when compared with non-acute disease group( P < 0. 05). After adjusting the TNM stage and surgical treatment,no significant difference in survival rate was found between the two groups. Conclusions:Gastric cancer patients with acute disease have lower survival rate. Acute disease may be not an independent prognostic factor, higher TNM stage and lower proportion of radical surgery are the main reasons for poor prognosis in gastric cancer patients with acute disease.

Objective To study the effects of nicotine on GDNF and dopamine content in striatum of Parkinson's disease (PD) rats.Methods 6-OHDA was stereoscopically injected to right side of the mesencephic ventral tegmental area (VTA) and substantia nigra pars compacta (SNpc). Nicotine of different dosages was intraperitoneally injected into PD rats.With biochemical,immunohistochemical techniques, we observed the changes of GDNF expression and dopamine content in striatum.Results Nicotine was intraperitoneally injected into PD rat models before or after the operation,striatum GDNF expression and DA content had significant improvement as compared with PD group (P

Objective To observe the cerebral activation by functional MRI(F MRI) during the thumb movement in different motor fashion. Methods Four stroke patients with hemiplegia were involved in this study During the examination by F MRI, these patients were asked to move thumbs in passive, active and overcoming resistance fashion. Results (1) During the thumb at unaffected side moving in active fashion, functional activity was observed in the contralateral primary motor cortex In passive fashion, however, functional activity was observed in contralateral somatosensory cortex The overcoming resistance motor test was associated with activity in bilateral primary motor cortex and somatosensory cortex (2) The same motor tests were made in movement of the thumb at affected side , functional activity appeared not only in primary motor cortex, somatosensory cortex of affected side, but also in basal ganglia(affected area), frontal lobe, supplementary motor cortex, somatosensory cortex, and contralateral primary motor cortex. Conclusion These results have proved the neurorehabilitation theory such as neuroplasticity and so on
