Thyroid carcinoma is the most frequent endocrine cancer,and most are found in women.Different pathologic types of thyroid carcinoma has different biologic behaviors,and onset is hidden,which results in difficults to diagnose the early thyroid carcinoma.With the development of the molecular biology,more researches are focus on thyroid carcinoma in recent years.This article reviews the tumor markers,oncogene and gene therapy of thyroid carcinoma.

Objective To compare the ability of auditory verbal learning,memory and retention between each side of thalamus and basal ganglia after stroke.Methods 63 patients with single lesion in thalamus or basal ganglia after stroke,34 patients with amnestic mild cognitive impairment (aMCI)and 34 healthy control subjects received auditory verbal learning test.Results There was an overall decline of immediate and delayed recall,retention ability in patients with single lesion of stroke as compared with the healthy control group(P＜0.05).Both the left thalamic stroke group [(19.0± 3.1)scores]and aMCI group[(17.6 ±3.3)scores]showed similar pattern in damaged recognition ability,while this ability still existed in the other three stroke groups.The ability of auditory verbal learning in the left thalamic stroke group[(2.2 ± 2.0)scores]and right thalamic stroke group[(2.1 ± 1.9)scores]were lower than in the healthy control group[(3.6 ± 1.8)scores](P ＜0.05).The retention ability in the left thalamus stroke group[(2.8±1.7)scores]and the right basal ganglia stroke group[(2.7 ± 1.9)scores]was decreased than in the healthy control group[(1.7±1.4)scores](P＜0.05).Conclusions There is decline of AVLT-learning,memory and retention ability in patients with single lesion stroke,especially in the left thalamus stroke patients.Moreover,the pattern of impairment in the left thalamus stroke is similar to aMCI but different from the other three stroke groups.

Surgical treatment has improved the prognosis of resectable pancreatic cancer considerably de-spite the generally aggressive behavior of its malignancy. Neoadjuvant therapy for pancreatic cancer has been shown effective in improving a survival benefit. Few prospective randomized controlled clinical trials (RCTs) on the use of neoadjuvant chemotherapy and chemoradiation has been done tp show the survival advantage of systemic chemotherapy (5-FU/FA or gemcitabine) following surgical resection. Up to now, there is no high-level evidence of any benefit deriving from neoadjuvant chemo therapy for pancreatic cancer. Well designed trials are needed to compare neoadjuvant chemotherapy with surgery to judge the value of neoadjuvant cherqo-therapy in multimodal treatment concepts of pancreatic cancer.

The flavin-containing monooxygenase 3 (FMO3) is an important hepatic microsomal enzyme. Numerous mutations of FMO3 gene have been reported, and polymorphic varients of the gene have been identified. Several studies indicated that variability in the expression of FMO3 involved in some nitrogen, or sulfur-containing durg metabolism. This review summarizes the genetic polymorphism of FMO3 and its role in drug metabolism and toxicity.

Objective To analyze functional improvement of spinal cord and the prognosis of two surgical approaches for the stenosis of cervical spinal canal;to investigate the mechanisms concerning post-terior decompression,fusion with ilium graft and internal fixation and 158 cases who underwent dorsal laminectomy from January 2001 to October 2002 were follow-up for at least 24 months and examined with the evaluation systems of Japanese Orthopaedic Association Score,somatosensary evoked essential and initiative range of motion to compare preoperative,short-term and long-term efficacy.Results According to selected standard of improvement rate,therapeutic effect of 56 sufferers among ventral approach group was analyzed,14 cases(25%)excellent,29 cases(51.79%)good,10 cases(17.86%)fair,3 cases(5.36%)poor;postoperative effect of 62 sufferers from dorsal approach group was analyzed,23 cases(37.10%)excellent,31 cases(50%)good,7 cases(11.29%)fair,1 case(1.61%)poor.Concerning JOA evaluation of spinal cord function,initiative range of motion and correlated parameters of SEP,there was significant difference between two decompression approach in postoperative periods.7 cases from anterior approach and 13 patients from posterior approach disturbed by postoperative complications were gradually rehabilitated through conservative of Cervical 5 spinal root',the essence of above-mentioned symptoms may be cervical cord impairment due to decompression process,which would be alleviated by appropriate intervention;2)The efficiency of posterior decompression get the better of anterior decompression in light of fundamentally enlarging available space approach became a little smaller than normal individuals,however,the corresponding parameters after anterior approach lower than the former two groups.

Objective To investigate the expression of signal transduction molecule STAT-1 in patients with chronic hepatitis B (CHB) who received interferon-alpha (IFNα) treatment with different responses. Methods A total of 13 CHB patients received IFNα treatment, among who 5 demonstrated complete viral response ( Group A) and 8 showed no response ( Group B). All patients underwent liver biopsy before and after the therapy. STAT-1 mRNA of liver tissue was semi-quantified by RT-PCR and levels of STAT-1 protein were detected by Western-blot. Results Absorbance values (A) of STAT-1 mRNA in group A and B were (1. 18±0.06) and (0.21±0.04) respectively (t =35.27, P<0. 01). The levels of STAT-1 protein of liver tissue in group A were also significantly higher than those in group B. Conclusion IFNα resistance may be closely related to the down-regulation of STAT-1.

Objective To study the prevalence and distribution of dental trauma in children and adolescents. Method A total of 347 patients with the permanent anterior teeth injured aged from 6 to 25 years were treated and selected from July 2008 to June 2009. Data of gender, age, site of accident occurred, number of teeth injured, and location and type of injury were taken from the dental records. Results Of them, there were male 219, female 128, and the ratio of male/female was 1.7:1.0, The highest incidence of tooth injuries occurred a-mong children of 10 to 13 years old. The common site of dental trauma was school. The majority of dental casualties had one tooth (38.0%) and two teeth (38.0%) injured. Of all types of dental injury, subloxation (19.8%), and enamel and dentin fractures without pulpa involvement (18.7%) were the most seen ones. Con-clusions The dental trauma in children and adolescents is a major problem that can not be ignored, and should be given persistent attention to prevent.

Objective To explore the feasibility of MR imaging for tumor-associated macrophages. Methods BALB/c mice and BALB/c ( nu/nu) nude mice were randomly divided into 6 groups ( before injection, 6, 24, 48, 72 hours and 7 days after injection) and 5 groups (before injection, 6, 24, 48 and 72 hours after injection) with each group of 3 animals, respectively. Macrophages ( RAW 264. 7) were incubated with HSA-IONPs ( dopamine/HSA coating iron oxide nanoparticle) containing 20 μg Fe/ml for 24 hours. Then, 5 x 106 labeled macrophages were collected and injected into subcutaneous 4T1 tumorbearing BALB/c mice and 22B tumor-bearing nude mice via tail vein. At different time points described above, all animals performed transverse and coronal T2-weighted MR scans using a 7. 0 T MR imaging unit.After sacrifice at different time points, tumor, liver and other organs were removed and processed for histological examination. Cytotoxicity of HSA-IONPs were assayed by MTT test, Statistics analysis adopt SPSS 11.5, the differences among groups were analyzed by one-way ANOVA. The difference was regarded as statistically significant when P <0. 05. Image J 1.42 software was used for the quantitative measurement of MR signal intensity. Results Effective cell labeling was confirmed by Prussian blue staining and transmission electron microscopy (TEM ). Iron uptake of single cell was 6. 19 pg. The mean absorbance values of cells incubated with HSA-IONPs for 24 hours in each group were 1. 95 ±0.19, 1. 82 ±0. 29,2. 10 ±0. 14, 1. 96 ±0. 18, 2. 05 ±0. 27 and 2.17 ±0. 22 respectively at different concentrations (5, 10,20, 40, 80, 160 μg/ml). Compared with that in control group (2. 00 ±0. 07), the absorbance values of cells in each group were not significantly different (F = 1.24,P>0. 05). There was a significant linear positive correlation between the labelled macrophage numbers and MR R2 values (r = 0. 99 ,P < 0. 05). In 4T1 tumor model, significant low signal intensity was found on T2WI surrounding the necrosis and cystic degeneration 6 hours after macrophage injection, with a signal reduction of 59.4%. The signal of tumor parenchyma showed no significant change, with signal reduction of 4. 8%. Irregular low signal ring could be seen at the junction of necrosis and parenchyma area at 24 hours after injection, with a signal reduction of 46. 8% and the signal loss was restored to 96. 8% around the necrosis and cystic degeneration. In 22B tumor model, multiple small scattered foci of low signal intensity were presented on T2WI around the necrosis and cystic degeneration 6 hours after macrophage injection with a signal drop of 46. 8% and reduced at 24 hours. 2, 3 or 7 days after macrophage injection, the morphology and location of low signal intensity were similar to those at 24 hours after injection on T2WI. But the signal intensity gradually decreased. The presence of labelled macrophages imaged by MRI were verified by pathology. Conclusion MRI is feasible for the delineation of tumor-associated macrophages. 24 hours after macrophage injection is the optimal time point for the assessment of macrophage migration and infiltration of tumor on T2WI. MRI can be used to evaluate the perfusion and neovascularization of tumor 6 hours after macrophage injection.

Objective　 In order to observe the long-term follow-up of 72 patients with transient ischemic attack（TIA），including the recurrence of TIA after the first attack, occurrence of complete stroke and myocardial infarction, fatality rate, causes of death, and the survival rate in each year and its 95% confidence interval, and to evaluate the clinical significance of neurovascular surgical indication.　Methods　 Seventy-two patients with TIA collected from 1959 to 1977 were followed up by means of face-to-face communication with the patients themselves or their families till 1998. And those aspects mentioned above were analyzed with the methods of cohort study, life table and other medical epidemiological statistics. 　Results　 The recurrent rate of TIA in 72 patients was 27.9%, and the occurrence rate of complete stroke 65.7%, and that of the myocardial infarction and the fatality 8.4% and 72.7%, respectively. There were 2(3.8%) patients died of myocardial infarction. It was showed from the study that the main cause of death was complete stroke, accounting for 59.6% of all dead patients, with the first cause in non-elderly patients was cerebral hemorrhage and that in the elderly patients was cerebral infarction. The 20-year survival rate was 39.9% and its 95% confidence interval was (28.4%，51.4%). Nineteen cases had the indication of neurovascular surgical operation, accounting for 26.6% of all 72 patients. 　Conclusions　 In the long-term follow-up study, the prognosis of patients with TIA was better than that of those with cerebral infarction. About one third of patients had the recurrence of TIA. The occurrence rate of the complete stroke was obviously higher than that of the myocardial infarction. It was considered that neurovascular surgical operation for preventing the happening of complete stroke in patients with TIA was limited.

OBJECTIVE:To promote the working efficiency of hospital prescription evaluation and improve pharmacists profes-sional quality through developmenting electronic prescription evaluation system (EPES) for outpatient department used by taking full advantage of large amount of information of electronic prescription. METHODS:By using system structure of Client/Server, Web Service middleware,programming tool of PowerBuilder and database technique of Oracle and sharing Hospital information sys-tem data,EPES was designed and applied,which could collect prescription information and generate summary form automatically after artificial prescription evaluation. RESULTS & CONCLUSIONS:Integration of outpatient electronic medical records,historical prescriptions and medical test results query system make the EPES carry comprehensive information which could make up for disad-vantages of paper prescription form in the aspect of obtaining outpatient medical records,historical prescriptions or medical test re-sults. EPES can accomplish general and special prescription evaluation and also pledges the equity and justness of process by ran-dom sampling. The operation of the system could improve the efficiency from taking 24-36 h in paper prescription form to 4-6 h to complete general prescription evaluation,which also improves professional quality of pharmacists by intensive training.
