Objective To observe the clinical efficacy of acupoint thread embedding plus Western medication in treating major epilepsy.Method Sixty epilepsy patients were randomized into a thread embedding group and a Western medication group, 30 cases each. The Western medication group was intervened by Western medication; the thread embedding group was given acupoint thread embedding based on the same Western medication treatment. Seizure frequency, seizure score, general efficacy and the improvement of adverse reactions due to Western medications were analyzed.Result Compared to the Western medication group, the thread embedding group was more effective in controlling seizure frequency (P<0.01), and reducing seizure score (P<0.05) and adverse reactions of Western medications (P<0.05); the general efficacy of the thread embedding group was superior to that of the Western medication group in treating epilepsy (P<0.05).Conclusion Acupoint thread embedding plus Western medication is effective in treating epilepsy, and is superior to the use of Western medication alone.

OBJECTIVESTo review the preliminary clinical experience with high-field-strength intraoperative magnetic resonance imaging (iMRI) suite with neuronavigation system in the pituitary adenoma operation with transsphenoidal approach.

METHODSFrom March 2009 to December 2010, 31 patients [range, 29 - 76 years, mean age (47 ± 11) years]of pituitary adenoma were operated with transsphenoidal approach and intraoperatively with a movable 1.5 T high-field-strength iMRI suite in combination with neuronavigation system. Tumor size was 1.8 - 7.3 cm, mean (3.5 ± 1.2) cm. Twenty-five cases were non-functional pituitary adenoma, 4 cases were prolactin-secreting pituitary adenoma, 2 cases were growth hormone-secreting pituitary adenoma. Thirty patients' resection with transnasal transsphenoidal approach were performed, one patient with transoral transsphenoidal approach was performed.

RESULTSIn 12 cases of 30 patients who planed to totally remove tumor, iMRI had revealed residual lesions and resulted in the change of the surgical strategy, 2 invasive cavernous sinus cases no further resection of the tumor because of internal carotid artery encasement, the other 10 cases resected further, eventually. Finally, 8 cases were totally removed. The ratio of total removal tumor was enhanced to 86.7% (26/30) from 60.0% (18/30). There was no perioperative mortality.

CONCLUSIONSHigh-field-strength iMRI suite with neuronavigation system provides valuable information of tumor resection that allows intraoperative modification of the surgical strategy. It could be very helpful to maximize the resection of the pituitary adenoma and minimize the injury to neurological function.

To develop a gene therapy strategy for treating bovine mastitis, a new mammary-specific vector containing human lysozyme (hLYZ) cDNA and kanamycin resistance gene was constructed for intramammary expression and clinical studies. After one time acupuncture or intracisternal infusion of healthy cows with 400 microg of the p215C3LYZ vector, over 2.0 microg/ml of rhLYZ could be detected by enzymatic assay for about 3 weeks in the milk samples. Western blotting showed that rhLYZ secreted into milk samples from the vector-injected cows had molecular weight similar to that of the natural hLYZ in human colostrums. Twenty days after the primary injection, the quarters were re-injected with the same vector by quarter acupuncture and even higher concentrations of rhLYZ could be detected. Indirect competitive ELISA of milk samples showed that the vector injection did not induce detectable humoral immune response against hLYZ. Clinical studies showed that twice acupuncture of quarters with the p215C3LYZ vector had overt therapeutic effect on clinical and subclinical mastitis previously treated with antibiotics, including disappearance of clinical symptoms and relatively high microbiological cure rates. These data provide a solid rationale for using the vector to develop gene therapy for treating bovine mastitis.

OBJECTIVETo investigate the relationship between two polymorphisms immediately upstream of the cyclooxygenase 2 (COX2) gene and preeclampsia in a South West Han Chinese population.

METHODSBlood samples from 205 patients with preeclampsia and 276 normal pregnant women as controls from Han Chinese in Chengdu area were analyzed by polymerase chain reaction-restriction fragment length polymorphisms.

RESULTSG and A allele frequencies for -1195G>A site were 48.54% and 51.46% in the patient group, respectively, and 40.40% and 59.60% in the control group, respectively. G and C allele frequencies for -765G>C site were 94.15% and 5.85% in the case group, respectively, and 94.38% and 5.62% in the control group, respectively. The AA genotype and variant A allelic frequencies of the -1195G>A SNP were significantly lower in patients with preeclampsia than in the control group (P<0.05), and the odds ratio for the risk of preeclampsia was 0.665 (95% CI: 0.444-0.982) in women homozygous for the variant COX2 A allele ( x²=4.233, P=0.047). The genotype and allele frequencies of the -765G>C polymorphism in patients with preeclampsia and controls showed no significant differences (P>0.05). Additional subgroup analyses (mild vs severe preeclampsia) of the two polymorphisms failed to reveal significant correlation for either genotypic or allelic frequencies. Furthermore, there was no significant association between the polymorphisms and blood pressure levels in the patient or control groups.

CONCLUSIONCOX2 -1195A homozygosity is associated with a decreased risk for preeclampsia in a South West Han Chinese population. On the other hand, the -765G>C polymorphism has no effect.

OBJECTIVETo investigate the expression of PTEN (phosphatase and tension homology deletion on chromosome 10, PTEN) and its pseudogene PTENP1 in acute leukemia (AL) and correlation between them, and to explore the role of PTENP1 on the PTEN expression in AL cells.

METHODSPTEN and PTENP1 mRNA expression were evaluated in bone marrow (BM) samples from 138 newly diagnosed AL patients and 15 healthy controls by quantitative real-time RT-PCR (qRT-PCR). pCDH1-PTENP1 3'UTR-GFP lentivirus vectors were constructed. 293T cells were transfected by calcium phosphate precipitation to produce retrovirus. HL-60 cell line was infected with the retroviral vectors expressing pCDH1-GFP and pCDH1-PTENP1 3'UTR-GFP respectively. The flow cell sorter was used to sort the HL-60 with GFP positively expressed. The mRNA expression of PTEN and PTENP1 was detected by qRT-PCR, the expression of PTEN protein by western blot, and the impact of PTENP13'UTR on the proliferation of HL-60 cells by MTT assay.

RESULTSAML patients showed significantly lower PTEN and PTENP1 mRNA expression in BM compared to healthy controls. Correlation analysis showed that the expression of PTEN and PTENP1 mRNA were positively correlated (P < 0.05). The 108 cases of PTENP1(+) AML were classified according to the prognostic classification of 2011 NCCN Clinical Practice Guidelines in AML, there was no difference among different subgroups. HL-60 cell line was infected with the retroviral vectors expressing pCDH1-GFP (control group) and pCDH1-PTENP1 3'UTR-GFP respectively. Compared with the control group, PTENP1 mRNA level of HL-60 infected with the retroviral vectors expressing pCDH1-PTENP1 3'UTR-GFP increased significantly, and PTEN mRNA level also increased. While the PTEN protein level and the cell growth rate of the PTENP1 3'UTR group didn't change significantly.

CONCLUSIONPTEN and PTENP1 mRNA expression level of BM cells from AL patients is significantly lower. There is a positive correlation between expression of PTEN and PTENP1 mRNA. PTENP1 may regulate the expression of PTEN in mRNA level.

OBJECTIVETo study the changes of intracellular interleukin-6 (IL-6) and interferon-gamma (IFN-gamma) expressions in children with acute lymphoblastic leukemia (ALL) at different stages, and to examine the correlation between IL-6 and IFN-gamma in ALL children.

METHODSThe levels of intracellular IL-6 and IFN-gamma in venous blood lymphocytes were detected by flow cytometry in 42 children with ALL at diagnosis and at remission stage. Twenty healthy children were used as the controls.

RESULTSThe intracellular IL-6 level in ALL children at diagnosis was 81.74+/-9.31, which was much higher than that in the Control group (5.67 +/- 0.96 ) (P < 0.01). The intracellular IFN-gamma level in ALL children (1.31 +/- 0.32) was significantly lower than that in the Control group (1.46 +/- 0.49) (P < 0.01). However, the intracellular IL-6 level (27.52 +/- 3.40) decreased remarkably in ALL patients at remission stage (P < 0.01), but was still higher than that in the Control group (P < 0.01). In contrast, the intracellular IFN-gamma level (1.97 +/- 0.72) increased noticeably in ALL patients at remission stage, which was higher than that at diagnosis and the Control group (P < 0.01). A negative correlation was found between the intracellular IL-6 and the IFN-gamma levels in ALL patients (r=-0.476, P < 0.05).

CONCLUSIONSIntracellular IL-6 and IFN-gamma levels may be used as the markers for monitoring the response to treatment in ALL patients. There is a negative correlation between intracellular IL-6 and IFN-gamma levels in ALL children.

OBJECTIVE: By observing the cerebral beta-amyloid precursor protein (beta-APP) expression in the chronic alcoholism rats with slight cerebral injury, to discuss the correlation of chronic alcoholism and death caused by traumatic subarachnoid haemorrhage (TSAH). METHODS: Sixty male SD rats were randomly divided into watering group, watering group with strike, alcoholism group and alcoholism group with strike. Among them, the alcohol was used for continuous 4 weeks in alcoholism groups and the concussion was made in groups with strike. In each group, HE staining and immunohistochemical staining of the cerebral tissues were done and the results were analyzed by the histopathologic image system. RESULTS: In watering group, there was no abnormal. In watering group with strike, mild neuronic congestion was found. In alcoholism group, vascular texture on cerebral surface was found. And the neurons arranged in disorder with dilated intercellular space. In alcoholism group with strike, diffuse congestion on cerebral surface was found. And there was TSAH with thick-layer patches around brainstem following irregular axonotmesis. The quantity of beta-APP IOD in alcoholism group was significantly higher in the frontal lobe, hippocampus, cerebellum, brainstem than those in watering group with strike and alcoholism group with strike. CONCLUSION The cerebral tissues with chronic alcoholism, due to the decreasing tolerance, could cause fatal TSAH and pathological changes in cerebral tissues of rats under slight cerebral injury.
