A case of eosinophilic lymphoid granuloma(ELG)was reported and the related literatures were reviewed.ELG is rare in clinic. The etiology and pathogenesis of ELG was unclear.The clinical feature includes enlarged lymph nodes which were always predilected for the head and neck regions,eosinophilic granulocytes and serum IgE rising.Lymphoid tissue hyperplasis formation of lymphoid follicles with active germinal centres are common in pathological examination.There is diffuse infiltration of eosinophils in interfollicular and perivascular zones. Surgery,drug therapy and radiotherapy are all effective for the treatment,but recurrence is often.

Syndromes constitute a core aspect in the study of Chinese medicine, and research on the concept of syndromes is important to the study of the process of modernization of traditional Chinese medicine. However, it is somewhat challenging to define a syndrome due to the complexity inherent in the subject, even with the assistance of the reductionism approach of modern medicine. Holistic and dynamic in nature and attaching much importance to functional changes, the newly emerging metabonomics is in many ways inline with the concepts of syndrome differentiation of pathological states in traditional Chinese medicine. Therefore, metabonomics has comparatively strong advantages in the very respect of revealing the natural laws of syndrome differentiation. By reviewing and analyzing the current research on the concept of syndromes and the application of metabonomic technology to exploring the essential core of syndrome differentiation, the authors illustrated the potential commonalities. This would also show the issues requiring attention between the study of syndromes and the metabonomic technology. In the meantime this study reflected the core problems in detail and put forward suggestions with regard to reaching solutions.

Purpose To investigate the expression of insulin-like growth factorIImRNA binding protein 3 ( IMP3 ) and microvessel density (MVD) in squamous carcinoma of the cervix (SCC) and analysis their relationship in SCC. Methods The expression of IMP3 and MVD was examined by immunohistochemistry SP method in normal cervical epithelium ( NCE) , low-grade cervical intraepi-thelial neoplasia (CIN-L), high-grade cervical intraepithelial neoplasia (CIN-H) and SCC. Results (1)The positive expression rates of IMP3 in NCE, CIN-L, CIN-H, SCC tissues were 0(0/15), 0(0/11), 37.5%(9/24) and 86.0%(43/50), the difference was statistically significant (x 2 =53.345, P=0.000). IMP3 expression was significant difference among NCE and CIN-H, SCC (P<0.008 3), and that was also among SCC and CIN-L, CIN-H (P<0.008 3). (2)The MVD count was increased with the development of cervical squamous lesion, there was significant difference among those groups (F=145.968, P<0.01), and the difference was al-so statistically significant between every two groups (P<0.05). The positive expression of IMP3 and MVD count in 50 cases of SCC tissues showed statistical difference in different pathologic grade, lymph node metastasis, and depth of tumor invasion groups ( P<0.05), but didn't in different patients’age groups (P>0.05). And the positive expression of IMP3 was closely related with MVD count in SCC tissues (rs =0.323, P<0.05). Conclusion IMP3 plays an important role in the occurrence, infiltration and metasta-sis of SCC, and the abnormal expression of IMP3 may relate with the angiogenesis of tumors.

Objective Toinvestigatetherelationshipbetweendifferenttypesofinternalwatershed infarctionandtandemstenosesofinternalcarotidartery(ICA).Methods Atotalof55patientswith internal watershed infarction confirmed by head MRI and diffusion-weighted imaging (DWI )examination were enrolled. They all underwent the extracranial internal carotid artery (ICA ) ultrasonography and intracranial cerebral artery MR angiography (MRA)examinations. According to the findings of imaging,the 55 patients with internal watershed infarction were divided into a simple internal watershed infarction (IWSI)group and an internal watershed infarction accompanied with ipsilateral cortical watershed infarction (C-IWSI)group. The relationship between the two types of internal watershed infarction and tandem stenoses of ICA was analyzed. Results (1 ) Of the 55 patients with internal watershed infarction,24 cases (43. 6%)were in the internal watershed infarction group and 31 cases (56. 4%)were in the C-IWSI group. The ipsilateral vascular stenosis were ICA 20 cases (36. 4%,including extracranial segment 11 cases and intracranial segment 17 cases),middle cerebral artery (MCA)44 cases (80. 0%), and tandem stenoses of ICA 15 cases (27. 3%). (2)Ipsilateral tandem stenoses of ICA:2 cases were in the IWSI group (intracranial ICA+MCA 2 cases);13 cases were in the C-IWSI group (extracranial ICA+intracranial ICA +MCA 4 cases,extracranial ICA + intracranial ICA 1 case,extracranial ICA + MCA 2 cases,and intracranial ICA+MCA 6 cases). (3)Compared with the IWSI group,the incidences of ipsilateral ICA stenosis and tandem stenoses of ICA in patients of the C-IWSI group were higher (54. 8%[n=17]vs. 12. 5%[n=3],41. 9%[n=13]vs. 8. 3%[n =2]),and there were significant differences(P =0. 001, 0.006]). The incidences of extracranial and intercranial ICA stenosis were higher than those of the IWSI group (35. 5%[n=11]vs. 0,45. 2%[n=14]vs. 12. 5%[n=3]),and there were significant differences (P=0.003,0.009).Conclusion Inthedifferenttypesofinternalwatershedinfarction,theincidenceof tandem stenoses of ICA is different. The IWSI patients with ipsilateral cortical watershed infarction often accompany by tandem stenoses of ICA.

Objective To explore the influences of age and duration of status convulsion (SC) on hippocampal neuron apoptosis by observing the dynamic change of neuron apoptosis in rats with different age when SC terminates. Methods Seizures were induced in infant rats (IRs) and adult rats (ARs) injected with lithium and pilocarpine intraperitoneally. Rats were sacrificed at 6 time points (3, 6, 12 hours and 1, 3, 7 days) after 30 minutes of SC, or 2 time points (3 hours and 1 day ) after 3 hours of SC respectively. The location and type of apoptotic cells were assessed by using terminal deoxynucleotidyl dUTP nick end-labeling (TUNEL) of brain sections in situ. The proportion of apoptotic cells was quantified by Annexin-Ⅴ-FITC apoptosis detecting method and analysed by flow cytometer. Results (1) SC induced neuronal apoptosis and necrosis mainly in the CA_1 and CA_3 regions of hippocampus. (2) As compared to the time point before SC, the proportion of apoptotic cells in IRs and ARs hippocampus was increased obviously at 3 hours point after 30 minutes of SC (IRs 0.55%?0.21%, ARs 0.53%?0.06%), and with a maximal induction at 12 hours in IRs (0.67%?0.18%) and 1 day in ARs (0.98%?0.38%). The apoptotic process continued at least for 3—7 days. (3) In IRs, the proportion of apoptotic cells was lower than in ARs at different time points after 30 minutes of SC, except 3 hours point. There was a significant difference between the two age groups at 1 day and 7 days after SC respectively. The age-related difference was more obvious after 3 hours SC. Conclusions (1) Severe seizure induces neuronal apoptosis in hippocampus. (2) Age and duration of SC might be the important factors in influencing the neuronal apoptosis. The neuronal apoptosis in hippocampus after SC would have a positive correlation with age and duration of SC.

This study was designed to determine the effects of the recombinant adeno-associated virus vector containing sense CD151 gene (rAAV-CD151) and antisense CD151 gene (rAAV-antiCD151) on the migration of Tca8113 cell. Functional fragment of CD151 gene was amplified by RT-PCR, and inserted into the vector pAAV in the sense direction and antisense direction, respectively. The rAAV-CD151 and rAAV-antiCD151 were produced and the titers were determined by dot blot. The CD151, at protein level, was detected by Western blot. The Transwell chamber was used to detect the effects of the rAAV-CD151 and rAAV-antiCD151 on the tumor cell migration. The titers of the rAAV-CD151 and rAAV-antiCD151 were 2 x 10(11) pfu/ml and 1.0 x 10(11) pfu/ml, respectively. The expression of CD151 was increased by 108% in the cells transfected with rAAV-CD151 and decreased by 79% in the cells transfected with rAAV-antiCD151, as compared with non-transfected cells, respectively. The number of the migrating cells was significantly increased in the cells transfected with rAAV-CD151 (93.56 +/- 11.59) and decreased in the cells transfected with rAAV-antiCD151 (24.00 +/- 4.36) as compared with non-transfected and rAAV-GFP transfected cells (53.00 +/- 6.56 and 46.00 +/- 7.00, P<0.05). It is an important molecular mechanism of the tumor metastasis that the overexpression of CD151 promotes the migration of the tumor cells. The rAAV-antiCD151 is a novel tool, which can reduce the expression of CD151 and inhibit the migration of the tumor cells, and brings us a new approach of anti-sene gene therapy targeted at CD151 in human carcinoma.
