Hyperuricemia mice model was established with uricase inhibitor (potassium oxonate) and uric acids in serum were observed. Polydatin (5, 10, 20 mg · kg(-1)) and benzbromarone (16.7 mg · kg(-1)) were given ig for 7 d in mice. Kidney tissues were used to detect gene contents ofurate anion transporter 1 (URAT1), organic anion transporter 1 (OAT1) and organic anion transporter 3 (OAT3) by real-time-PCR. The results showed that polydatin and benzbromarone can significantly reduce uric acid in blood of hyperuricemia mice (P < 0.05), compared with the model group. URAT1, OAT1 and OAT3 contents of the kidney in hyperuricemia mice changed significantly (P < 0.05), compared with the blank group. Polydatin can significantly inhibit the changing trends in these genes induced by potassium oxonate in a dose-dependent manner, the difference was significant (P < 0.05), compared with the model group. Those indicated that polysatin could reduce the level of the serum uric acid through promoting uric acid excretion.

Objective To investigate the effects of ischemic pre- and postconditioning on cerebral glycogen synthase kinase-3 beta (GSK-3β) activity in a rat model of global cerebral ischemia-reperfusion (I/R).Methods Forty male Wistar rats weighing 200-230 g were randomly allocated into 4 groups (n =10 each) : Ⅰ group sham operation (group S); Ⅱ group I/R; Ⅲ group ischemic preconditioning (group IPR) and Ⅳ group ischemic postconditioning (group IPO). The animals were anesthetized with intraperitoneal 10% chloral hydrate 0.4 ml/100 g. Global cerebral ischemia was induced by four-vessel-occlusion in group Ⅱ , Ⅲ and Ⅳ. Bilateral vertebral arteries were cauterized and bilateral carotid arteries were occluded for 10 min. In group IPR cerebral ischemia was preceded by 3 cycles of 10 s ischemia followed by 30 s reperfusion. The group IPO received 3 cycles of 30 s reperfusion followed by 10 s ischemia at the end of 10 min cerebral ischemia. The animals were killed 2 days later. The brains were immediately removed for determination of neuronal apoptosis in the cortex (by TUNEL), the infarct size (by TTC), p-GSK-3β activity (by spectrum assay) and the expression of Bcl-2, Bax and Caspase-3 (by SP). Linear correlation of p-GSK-3β activity with the number of apoptotic neurons in the cortex and cerebral infarct size was analyzed. Results Cerebral I/R significantly increased the number of apoptotic neurons in the cortex and infarct size, decreased p-GSK-3β activity, down-regulated Bcl-2 expression and up-regulated Bax and Caspase-3 expression in group I/R as compared with group S. Ischemic pre- and postconditioning significantly attenuated these cerebral I/R-induced changes. The p-GSK-3β activity was negatively correlated with the number of apoptotic neurons in the cortex and cerebral infarct size. Conclusion Ischemic pre- and postconditioning reduces cerebral I/R injury through inhibiting the activity of GSK-3β.

[Objective]To investigate the significance of the high-risk human papilloma virus (HPV)detection in the screening and diagnosis of cervical lesions.[Methods] The high-risk HPV DNA test results of 797 patients with cervical lesions who all accepted cytology and histopathology test were collected and analyzed retrospectively.[Results]The high-risk HPV DNA positive rates in cervicitis,cervical intraepithelial neoplasia(CIN)Ⅰ,CIN Ⅱ,CIN Ⅲ and cervical cancer were 53.41％(188/352),70.91％(117/165),87.63％(85/97),97.90％(140/143),97.50％(39/40),respectively.The sensitivity and negative predictive value of the high-risk HPV DNA detection for CIN Ⅱ and more serious lesions were 96.66％(318/329),93.29％(153/164),respectively.The detection rate of CIN Ⅱ and more serious lesions in patients with atypical squamous cells of undetermined significance(ASCUS)and positive high-risk HPV DNA was 30.03％(94/313),while the rate in patients with negative high-risk HPV DNA was 1.55％(2/129).[Conclusions] The more serious the cervical lesion is,the higher high-risk HPV DNA positive rate is.It is most closely related with CIN 11 and cervical cancer.The high-risk HPV DNA detection has high sensitivity and negative predictive value for CIN Ⅱ and more serious lesions.The high-risk HPV DNA detection has high negative predictive value in CIN Ⅱ and more serious lesions in ASCUS.

Objective To survey gene expression profiles in nonlesional refractory temporal lobe epilepsy(TLE)and to further verify the difference of gene expression.thus to evaluate the possible molecular pathogenesis of this kind of epilepsy that can help to supply a new way for the diagnosis and treatment.Methods The TLE samples and control cases were studied by means of cDNA microarray consisting of 1 8 000 genes.Reverse transcription polymerase chain reaction(RT-PCR)Was performed to measure the expression alterations of SH3GL2.BTNN2A2 and KCNJ4 mRNA in temporal cortex samples from patients who had undergone temporal lobectomy surgery for intractable epilepsy.Tissue from 10 subjects who did not have epilepsy served as controls.Results The known genes differently expressed in those TLE samples involved immunity correlation factor genes,signal conduction genes,ion channel transportation genes;mitochondria function genes and SO on were identified.Among which.the expression of SH3GL2 mRNA Was significantly increased in epileptic brain(1.022±0.547)compared with the controls(0.446±0.171,t=-3.181).In TLE group(0.481±0.196),the expression of BTN2A2 mRNA was also significantly higher than that of control subjects(0.243±0.111,t=3.351).Compared with control group(O.795±0.112),the expression of KCNJ4 mRNA Was significantly decreased in TLE patients(0.438±0.178).Conclusions cDNA microarray is an efficient and high.throughout method to survey gene expression profiles in intractable temporal lobe epilepsy.The variation of those gene expressions might be a potential etiological agent for TLE that may offer a novel target for anticonvulsant therapy.

Objective The aim of the current study was to investigate the prognostic value of extracapsular lymph node spread in gastric cancer patients and to find correlations with clinicopathological parameters.Methods Clinicopathological data of 131 gastric cancer patients who underwent gastrectomy with lymphadenectomy were analyzed retrospectively. The number of metastatic lymph nodes with extracapsular spread were determined. Multivariate analysis was performed to find the clinical prognosis affecting extracapsular lymph node involvement. Results Seventy-eight patients (59.5%)had perigastric lymph node metastasis. Fortysix cases were detected extracapsular lymph node involvement. The 5-year cumulative survival rate for patients with extracapsular lymph node spread was 13. 5% , while 32 patients with lymph node metastasis but without extracapsular involvement had a 5-year survival rate of 39.3%. The survival rate decreased significantly with the increase of extracapsular lymph node involvement(P =0.001). Extracapsular lymph node involvement was significantly associated with the higher number of metastatic lymph nodes, the location of lymph node metastasis, tumor invasion depth and distant lymph node metastasis. In the multivariate analysis, extracapsular lymph node spread also remained as an independent prognostic factor(P =0.003). Conclusions Extracapsular lymph node involvement is a convenient and reliable prognostic index, and is an independent prognostic factor in gastric cancer patients. In future staging systems for gastric cancer, extracapsular lymph node involvement should be considered, be pathologically checked and reported in order to determine extracapsular spread status.

Objective To evaluate the efficacy of aminophylline for prevention of the negative chronotropic effect of remifentanil.Methods Forty patients undergoing general anesthesia,aged 20-55 yr,with body mass index of 18-25 kg/m2,of ASA physical status Ⅰ or 1Ⅱ,were randomly divided into control group (group C) and aminophylline group (group AP),with 20 patients in each group.At 30 min before induction of anesthesia,normal saline 20 ml was infused intravenously in group C,and aminophylline 3 mg/kg was infused intravenously in group AP.Midazolam 0.1 mg/kg was then injected intravenously.Remifentanil 2 μg/kg was injected intravenously after the patients fell asleep and then artificial ventilation was performed.Vecuronium 0.1 mg/kg,fentanyl 3 μg/kg,and etomidate 0.3 mg/kg were injected intravenously 7 min later.The patients were then endotracheally intubated and mechanically ventilated.HR and MAP were recorded before induction of anesthesia (T0),after falling asleep (T1),and at 0,1,3,5 and 7 min (T2-6) after the end of remifentanil injection.Low frequency (LF) and high frequency (HF) were recorded at T0,T1 and T2,and the ratio of LF/HF was calculated.Results Compared with the baseline value at T0,MAP and HR were significantly decreased at T2-6 in the two groups,and LF and HF were decreased at T1,and LF/HF ratio was increased at T1 in group AP.HR and LF/HF ratio were significantly higher,and LF and HF were lower at T1 in group AP than in group C.Conclusion The efficacy of aminophylline for prevention of the negative chronotropic effect of remifentanil on the hearts of patients is good.

Objective To analyze the clinical efficacy of daily online cone-beam computed tomography (CBCT)-guided stereotactic body radiation therapy (SBRT) for primary and metastatic lung cancer and its related factors.Methods From May 2009 to May 2013,36 patients with lung cancer were treated with SBRT,including 24 patients with primary lung cancer and 12 patients with metastatic lung cancer.The biologically effective dose at 10 Gy was ≥ 100 Gy in 85.7％ of 42 lesions.Before each delivery,CBCT was acquired,and online automatic or manual registration was performed to make the tumors on CBCT within the planning target volume/primary gross tumor volume;the setup threshold was not set,and the couch was moved for correction.Results The 1-,2-,and 3-year sample sizes were 36,29,and 26,respectively.The 1-,2-,and 3-year local control (LC) rates were 96％,89％,and 72％,respectively.The 1-,2-,and 3-year cancer-specific survival (CCS) rates were 82％,74％,and 64％,respectively.The 1-,2-,and 3-year overall survival (OS) rates were 78％,64％,and 53％,respectively.Univariate analysis found no factors associated with LC.Multivariate analysis revealed no factors associated with OS.Both univariate and multivariate analyses showed that only tumor location (central type or peripheral type) was associated with CCS;the mean values (95％ confidence intervals) of CCS in patients with central-type and peripheral-type lesions were 21.4 months (13.2-29.6 months) and 42.3 months (35.7-49.0months),respectively (P=0.024).Conclusions Daily online image-guided SBRT for primary or metastatic lung cancer can lead to a satisfactory LC.
