P53 gene (exon7~8) mutatins and p53 proteins and HPV 6,11,16,18-DNA were examined in 49 cervical carcinoma by immunohistochemistry, polymerase chain reaction (PCR) and single strand conformation polymorphism (SSCP) in order to investigate their role and mutual relation and clinical significance in the onco genesis of cervical carcinoma. The results showed that first, p53 proteins posit ive rate was 48.98%, and not outstandingly related to the differentiation and the invasive degree of cervical carcinoma(P>0.05); the defects of P53 gene (exon7~8) were not found but P53 (exon7~8) mutations were detected in 7 of 49(14.29%) cervical carcinoma; then, HPV16-DNA positive rate was much higher than HPV6,11,18-DNA positive rate respectively(P<0.001),and the different HPV-DNA was simultaneously tested in one cerv ical carcinoma; last, not all cases of P53 mutations had p53 proteins posi tive, but the cases of P53 mutations and p53 proteins negative certainly had HPV infections, and HPV positive cases were much more than its negative one in the cases of p53 proteins positive(P<0.001). These results proved that the oncogenesis of cervical carcinoma is mainly associated with HPV16 infections, and second related to P53 (exon7~8) mutations. p53 proteins positive results from P53 mutations or/and HPV infections in cervical carc inoma.

Objective To evaluate the value of magnetic source imaging(MSI) in localizing the epileptic foci of patients with histologically proved grey matter heterotopia(GMH) and seizure. Methods MSI examinations were performed on 8 patients with GMH and seizure. The location of the epileptic foci defined by MSI was compared with the results of the ECoG. After imaging examinations, all patients received operation with 13-48 months follow up to observe the effectiveness of the operation. Results Among the 8 patients, 1 had hippocampal sclerosis,2 had focal cortical dysplasiaof type Ⅰ B and 1 had focal cortical dysplasia of type Ⅱ B. MRI showed normal findings in 2 cases, subcortical heterotopia in 4 cases, and nodulor heterotopia in 2 cases with one having schizencephaly. The epileptic foci defined by MSI were at right temporal lobe in 2 cases, left frontal lobe in 2 cases, biparietal lobe in1 case, left parietal lobe in 1 case, left temporal lobe in 1 case, and left frontal-parietal lobe in 1 case. The epileptic foci defined by MSI were completely overlaid with area of GMH in 4 cases, closely behind the area of GMH in case, and partly overlaid with area of GMH in 1 cases with size larger than that of the latter. One patient showed two epileptic foci with one located within the area of GMH and the other one 2 centimeters anterior to the area of GMH.One case's epileptic focus located 2 centimeters posteolateral to the area of GMH . The locations of the epileptic foci defined by MSI showed no difference with those defined by ECoG in all patients. According to Engel classification of treatment effect of epilepsy, 6 patients achieved Engle class Ⅰ ( seizure free after operation ), and 2 patients Engel class Ⅳ ( no changes in the frequcenty of occurrence of seizures before and after operation ). Conclusion MSI can noninvasively and precisely localize the epileptic foci before operation in patients with GMH and seizure.

Pancreatic cancer is characterized by high invasiveness,high malignancy and poor prognosis. Therefore,it is urgent to find biomarkers for early diagnosis and to develop targeting drugs for treatment of pancreatic cancer. MicroRNAs (miRNAs)are single-stranded,non-coding small RNA molecules with a length of 18-25 nucleotides and are highly expressed in pancreatic cancer. MiRNAs play important roles in cell proliferation,differentiation,apoptosis,invasion and metastasis,and are associated with adverse prognosis and resistance to chemotherapy in pancreatic cancer. As a new target for diagnosis and treatment of pancreatic cancer,miRNA-21 has become the hot spot of clinical research. This article reviewed the advances in studies on miRNA-21 in the pathogenesis,diagnosis and treatment of pancreatic cancer.

BACKGROUND: Great concerns haven been given increasingly on inhibition of nutrient with antioxidation efficacy on lipid peroxidation and its effect on prevention of cardiac vascular disease.OBJECTIVE: To probe into the effects of plantain seed that acts on eliminating oxygenic free radical and antioxidation on lipid metabolism and antioxidation in rats.DESIGN: Randomized control experiment was designed.SETTING: Experimental Room of Pharmacology and Toxicology of New Drug in Hebei Province.PARTICIPANTS: The experiment was performed in Experimental Room of Pharmacology and Toxicology of New Drug in Hebe Province from January to December 2004, in which, 40 SD rats were employed, provided from Hebei Experimental Animal Center, of healthy grade I, mass weighted (210±22) g and of either sex. They were randomized into 5groups, named, blank control, positive control, low dosage experiment group, moderate dosage experiment group and high dosage experiment group, 8 rats in each one.METHODS: In blank control, the rats were bred everyday with basic forage that was tallied with AoAc animal nutrient criteria and they were free of drinking. In positive control, the rats were bred with high-lipid forage and free of drinking. In the groups of low, moderate and high dosages of plantain seed, the rats were bred with 2.5 g/kg, 5 g/kg and 15 g/kg plantain seed successively besides high-lipid forage and they were free of drinking. The weight was measured and the food intake was recorded every week. Fasting blood was collected to check total cholesterol in serum once every two weeks. The experiment was end in 12 weeks. Under anesthesia,the blood was collected from hypogastric aorta to check the level of serum blood lipid and the activities of superoxide dismutase (SOD) and catalase.After blood collection, the heart and liver were extracted immediately for management to measure SOD activity and content of lipid peroxide (LPO)in myocardial tissue and the activities of catalase and glutathione peroxidase in liver tissue.MAIN OUTCOME MEASURES: Level of blood lipid and activities of SOD and catalase in rats.RESULTS: Forty rats were employed and all entered result analysis. [1]Serum total cholesterol: It was lower significantly in high dosage group compared with positive control [(1.40±0.13, 1.83±0.13) mmol/L, P < 0.05].[2] Serum SOD activity: It was lower remarkably in positive control compared with blank control [(174.29±10.33, 193.19±.7813) NU/mg, P < 0.05].[3] LPO content in serum: It was higher significantly in positive control compared with blank control [(3.64±0.26, 2.91±0.50) mmol/mg, P < 0.05]and it was lower significantly in moderate dosage group compared with positive control (3.13±0.26, 3.64±0.26, P < 0.05). [4] Activity of catalase in liver tissue: It was lower remarkably in positive control compared with normal control (34.64±3.26, 44.72±2.67, P < 0.05) and it was higher remarkably in moderate dosage group compared with positive control (44.84±3.79,34.96±3.64, P < 0.05).CONCLUSION: Plantain seed reduces the levels of total cholesterol,triglycerin (TG) and LPO in serum and increases SOD activity. At the concentration of 15 g/kg, plantain seed acts most remarkably on eliminating oxygenic free radical and antioxidation and alleviates lipid metabolic disturbance.

Objective To assess the value of magnetic source imaging (MSI) in localizing the linguistic center of auditory function of epileptic patients before operation. Methods Epileptic focus and the linguistic center of auditory function in 24 patients were localized with MSI before operation. And the relationship between epileptic focus and auditory language area was observed. Results The linguistic center of auditory function was localized in left temporal lobe in 14 patients, in right temporal lobe in 5 patients and in bilaterial temporal lobe in 5 patients. Epileptic focus was localized in left temporal lobe in 14 patients, in left temporal lobe and left parietal lobe in 1 patient, in right temporal lobe in 4 patients, in right temporal lobe and parietal lobe in 1 patient, in left frontal lobe and left temporal lobe in 1 patient, in right frontal lobe, right temporal lobe and parietal lobe in 1 patient, and in bilaterial temporal lobe in 2 patients. Epileptic focus was superimposed with the linguistic center of auditory function in 10 patients, while was not superimposed with the linguistic center of auditory function in 10 patients. The epileptic focus was localized in front of the linguistic center of auditory function in 3 patients, in behind of the linguistic center of auditory function in 1 patient. The lesion of the patient suffered from dysembryoplastic neuroepithelial tumor was not excised completely because the epileptic focus was superimposed with the linguistic center of auditory function, and the patient appeared language functional disturbance after operation in short period, remaining auditory hallucination occasionally after operation. Conclusion Epileptic focus and the linguistic center of auditory function can be localized accurately and the relationship between them can be observed clearly with MSI. MSI is useful to reduce the occurrence of language disturbance after operation.
