Objective To study the mRNA expression of myelin basic protein (MBP) and myelin oligodendregha glyeoprotein (MOG) in hippocampus of rats following global brain ischemia.Method The four- vessel occlusion animal model in the Sprague-Dawley rats was used in this study.The mRNA expression levels of MBP and MOG in the hippocampus of rats were analyzed by reverse transcription polymerase chain reaction (RT- PCR) at day 2,4,7,14 and 28 days after global brain ischemia.There were eight rats at each time-point and sham operated group.Results The mRNA expression of both MBP and MOG in hippocampus of rats decreased at 2 days after global brain ischemia.The gene expression of myelin gene decreased significantly at 7 days and it reached to the lowest level at 28 days.Compared with sham operated group,the gene expression of MBP and MOG in hippocampus of rats decreased significantly at 7,14 and 28 days after global brain ischemia (P

Objective To study effects of low molecular weight heparin on liver fibrosis and the serum levels of TGF-?_1 in patients with chronic hepatitis B virus.Methods 45 patients with chronic hepatitis B virus were randomized into control group(the routine strategy)and trial group(the routine strategy + low molecular weight heparin).The period of treatment is 3 weeks.Serum hepatic fibrosis indices before and after heparin treatment were examined by RIA,the levels of serum TGF-?_1 before and after heparin treatment were examined by ELISA.Results Hepatic functions became significantly better in trial groups,serum PⅢP and type IV collage levels and the levels of serum TGF-?_1 in trial group decreased significantly after treatment.Conclusions The mechanism of anti-fibrosis action of LMWH may inhibited production of TGF-?_1 in patients with HBV.

Objective To explore the relationship between DNA repair gene XRCC1 and XPD polymorphisms and individual susceptibility to prostate cancer. Methods PCR-restriction fragment length polymorphism assay was used to analyze the XRCC1 (C26304T and G28152A) and XPD A35931C polymorphisms in 358 prostate cancer patients and 312 healthy controls. Unconditional logistic regression analysis was performed to calculate odd ratio (OR) and 95% confidence interval (CD for estimating the correlation between different genotypes and prostate cancer risks. Results Forty-seven(13.1%) cases present XRCC1 28152AA genotype in prostate cancer group, while 24 cases in the control group (7. 1%), individuals with this genotype had a significantly increased risk for prostate cancer (OR 1. 924, 95%CI=1.126 - 3. 288, P=0. 017). There was no significant difference between two groups at XRCC1 C26304T and XPD A35931C sites. Combined analysis of the three sites polymorphisms showed that individuals with XRCC1 28152 AA and XPD 35931AC+CC genotype had a higher risk of prostate cancer than those with three wild genotypes (OR = 3. 087,95%CI 1. 081 - 8.813;OR = 3. 376,95%CI 1.067-10.683;OR 3. 216,95%CI=1. 439-7.188,P = 0. 004). Analysis stratified by age of onset, PSA, Gleason score and T stage revealed that XRCC1 28152AA and XPD 35931 AC+CC high-risk genotype was especially associated with early age at onset of prostate cancer (P<0. 05). Conclusions The XRCC1 and XPD genotypes may be contributed to the risk of developing prostate cancer, particularly for younger patients.

Objective Evaluation the Fractionated Stereotactic Radiotherapy (FSRT) for the patients with small-cell lung cancer (SCLC) after the whole brain radiotherapy (WBRT) failure.Methods We retrospectively analyzed 35 patients with brain metastases from small-cell lung cancer treated with linear accelerator FSRT after the WBRT failure. Multivariate analysis was used to determine significant prognostic factor related to survival.ResultsThe following-up rate was 100％.The median following-up time was 11 months.The median over-all survival (OS) time was 10.3( 1 -30) months after FSRT.Controlled extra cranial disease was the only identified significant predictor of increased median OS time (χ2 =4.02,P =0.045 ).The median OS time from the diagnosis of brain metastasis was 22 (6 - 134 )months.14 patients died from brain metastasis,14 from extra-cranial progression,1 from leptomeningeal metastases,and 3 from other causes. Local control at 6 months and 12 months was 91％ and 76％,respectively.No significant late complications.New brain metastases outside of the treated area developed in 17％ of patients at a median time of 4(2 -20) months; all patients had received previous WBRT.ConclusionsFractionated stereotactic radiotherapy was safe and effective treatment for recurrent small-cell lung carcinoma brain metastases.

Objective:To investigate the effects and potential mechanisms of resveratrol on obesity in elderly mice.Methods:In this study, 3 groups were randomly formed for 32-week-old mice and for 48-week-old mice.The normal diet group received regular chow and 0.3 ml saline by gavage once a day, the high-fat diet group received a high-fat diet(containing 21% fat and 1.25% cholesterol)and 0.3 ml saline once a day, and the high-fat diet plus resveratrol group received a high-fat diet and resveratrol(22.4 mg/kg, dispersed in 0.3 ml saline)by gavage once a day.After 12 weeks, body weight and adipose tissues were measured.Plasma leptin concentrations were determined by an enzyme-linked immunosorbent assay(ELISA), and values for hypertrophic obesity-related indexes of mice were obtained by quantitative real-time PCR.Results:The body weight and the proportion of subcutaneous fat tissues were lower in the high-fat diet plus resveratrol group than in the high-fat diet group[(34.43±3.23)g vs.(53.16±2.16)g, (3.21±1.58)% vs.(4.86±0.64)%, P<0.01], and were similar to those in the normal diet group.Resveratrol had a more obvious inhibitory effect on leptin in elderly mice than in middle-aged mice.In elderly mice, the plasma leptin concentration was lower in the high-fat diet plus resveratrol group than in the high-fat diet group[(0.015±0.009)g/L vs.(0.100±0.027)g/L]and the normal diet group( F=19.85, P=0.001), and it was similar to that in the middle-aged mice on a normal diet.Resveratrol significantly increased the expression of peroxisome proliferator-activated receptor gamma(PPARγ)and glucose transporter 4(GLUT4)and reduced the expression of tumor necrosis factor-α(TNF-α)( F=10.79, 9.31 and 7.02, P=0.003, 0.006 and 0.010). Conclusions:Resveratrol can significantly improve hypertrophic obesity in elderly mice, and the inhibition of leptin secretion and up-regulation of PPARγ may be the key mechanisms.

OBJECTIVETo explore therapeutic effects of bone setting manipulation for the treatment of over degree II supination-eversion fractures of ankle,and analyze manipulative reduction mechanism.

METHODSFrom 2005 to 2008, 95 patients with over degree II supination-eversion fractures of ankle were treated respectively by manipulation and operation. There were 43 cases [11 males and 32 females with an average age of (44.95 +/- 12.65) years] in manipulation group, and 2 cases were degree II, 11 cases were degree III, and 30 cases were degree IV. There were 52 cases [21 males and 31 females with an average age of (39.96 +/- 13.28) years] in operative group,and 6 cases were degree II, 18 cases were degree III, and 28 cases were degree IV. Bone setting manipulation and hard splint external fixation were applied to manipulative group. Operative reduction internal fixation was performed in operative group. X-ray was used to evaluate reduction of fracture before and after treatment, 2 months after treatment. Ankle joint function was evaluated according to Olerud-Molander scoring system after 6 months treatment.

RESULTSAll patients were followed up with good reduction. Three cases occurred wound complication in operative group, but not in manipulative group. In manipulation group, 19 cases got excellent results, 20 cases good and 4 cases fair; while in operative group, 30 cases got excellent results, 20 cases good and 2 cases poor. There were no significant differences in fracture reduction and ankle joint function recovery between two groups (P > 0.05). Efficacy of operative treatment was better than that of manipulative treatment at degree IV fracture (P < 0.05).

CONCLUSIONBone setting manipulation is a good method for treating supination-eversion ankle joint fractures, which has advantages of simple and safe operation, reliable efficacy. For ankle join fracture at degree IV, manipulative reduction should be adopted earlier, and operative treatment also necessary

OBJECTIVETo evaluate the effects of Shengli capsules on the sexual ability of normal and castrated male rats.

METHODSShengli capsules were given by intragastric administration to 100 experimental male rats at different doses of 0.35, 0.70 and 1.40 g / kg. Data were collected and analyzed, including capture latency period, times of capture, sexual endurance and times of ejaculation, to assess the effects of Shengli capsules on the sexual ability of the rats. The Castrated Animal Impotence Model was employed to determine the erectile latency period and the function parameters of the preputial gland, seminal vesicle and prostate, so as to test the effects of Shengli on the development of the rats'sexual organs.

RESULTSShengli was proved to be effective in shortening copulation latency in the dose groups of 0.35, 0.70 and 1.40 g / kg (P < 0.01), increasing significantly the frequency of capture in the high- and low-dose groups of 0.35 and 1.40 g / kg (P < 0.05), reducing the latency period to erection in the low-dose group of 0.35 g / kg, and blocking the shrink of the seminal vesicle and prostate in the medium-dose group of 0.70 g / kg.

CONCLUSIONShengli is significantly effective in enhancing the sexual ability of male rats: it can boost libido, increase erection frequency and improve sexual performance. However, further studies have yet to be done on its action mechanisms.

BACKGROUNDBevacizumab, a humanized monoclonal antibody against vascular endothelial growth factor, has shown promising activity in recurrent malignant gliomas. We reported the treatment response for the combination of bevacizumab and chemotherapy in a series of six patients with recurrent malignant glioma and investigated the molecular alterations in cancer pathways using the surgical biopsies from these patients.

METHODSStandard therapy with primary resection followed by adjuvant chemoradiotherapy had failed in all patients. Bevacizumab was administered at a dose of 10 mg/kg every 2 weeks. Concomitantly, four patients received temozolomide (50 mgxm(-2)xd(-1)), one patient irinotecan (125 mg/m(2) every 2 weeks) and one patient topotecan (1.2 mgxm(-2)xd(-1)). Response to therapy was mainly determined by magnetic resonance imaging. The expression of Ras, phosphorylated mitogen activated protein kinase (p-MAPK), phosphorylated AKT (p-AKT), phosphorylated mammalian target of rapamycin (p-mTOR) and phosphorylated signal transducer and activator of transcription 3 (p-STAT3) were semiquantitatively assessed by immunohistochemistry using surgical biopsies before the initial treatment.

RESULTSFive of the six patients had a radiographic response. Three were complete response, and two were partial response. Only one patient had progressive disease. The 6-month progession-free survival (PFS) was 33% and the median PFS was 15 weeks, with a range of 6 to more than 60 weeks. Of the three core pathways analyzed in this study, the Ras/MAPK and phosphatidylinositol-3-kinase (PI3K)/AKT/mTOR pathways were more likely to be associated with the treatment response to bevacizumab. In two younger patients (ages < 50) with complete response, simultaneous overexpression of p-MAPK, p-AKT and p-mTOR might be the crucial feature.

CONCLUSIONSBevacizumab in combination with chemotherapeutic agents may be an effective strategy for patients with recurrent malignant glioma. Activated MAPK and AKT might be possible biomarkers for selecting suitable patients for this targeted therapy.

OBJECTIVETo explore the clinicopathologic characteristics, treatment and prognosis of differentiated thyroid carcinoma (DTC) in adolescents.

METHODSThe data of 46 patients with DTC under the age of 18 years were retrospectively reviewed.

RESULTSTwenty patients were misdiagnosed in this group (43.5%). All patients received operation, including 39 unilateral neck dissection and 6 bilateral neck dissection, followed by postoperative thyrotropin suppressive therapy. There were 42 cases of papillary carcinoma (91.3%) and 4 cases of follicular carcinoma (8.7%). Cervical lymph node metastasis was found in 39 cases (84.8%). In the follow-up period of 1 to 25 years (mean 10 years), no death of thyroid carcinoma occurred.

CONCLUSIONSThe most common DTC in adolescents is papillary carcinoma with better prognosis regardless of the higher incidence of cervical lymph node metastasis. The optimal extent of primary thyroidectomy and neck dissection followed by postoperative thyrotropin suppressive therapy in adolescents with DTC may improve the quality of life and decrease the incidence of complications.
