Objective To investigate the relationship between hOGG1 and XPD gene polymorphism and genetic susceptibility of gastric cancer.Methods This study was carried out in Dongying Shengli Petroleum Administration Bureau Hospital.Under the narrow band imaging(NBI) mode,the blood samples of a total of 98 gastric cancers and 80 controls without cancers were collected.Genetic polymorphisms of DNA repair genes were identified by polymerase chain reaction restriction fragment length polymorphism(PCR-RFLP),then its relationship with cancers was analyzed.Results Carrying 326Cys allele with the wine increased the risk of gastric cancer; Lys 751Gln genotype increased the susceptibility of the gastric cancers (OR =1.486,0.73 ～ 3.025).Conclusion Lys751 Gln genotype increases the risk of gastric cancer.

Objective:Matching pursuit algorithm(MAP),for its good parametric characterization, is applied in Magnetoencephalography(MEG) to study time-frequency distribution. Methods:This paper proposes to apply a high-resolution time-frequency analysis algorithm, the matching pursuit (MP), to extract detailed time-frequency components of SEF signals. Results: Experimental results on cortical SEF signals of several normal subjects show that a series of stable SEF time components can be identified using the MP decomposition algorithm. Conclusion:This study shows that there is a set of stable and minute time-frequency componentsin SEF signals, which are revealed by the MP decomposition. These stable SEF components have specific localizations in the time domain and may provide a reliable index for clinical research of brain function and brain disease pathogenesis.

BACKGROUND:There are few reports about the effect of serum-free culture on the differentiation of rat adipose-derived stem cel s into vascular endothelial cel s.
OBJECTIVE:To investigate the isolation, serum-free culture of rat adipose-derived stem cel s differentiating into vascular endothelial cel s.
METHODS:The rat adipose-derived stem cel s were isolated from male Sprague-Dawley rats and expanded to the third passage by enzymatic digestion-adherent explants method. In the experimental group, rat adipose-derived stem cel s were cultured in serum-free medium for 24 hours. In the control group, rat adipose-derived stem cel s were cultured in low-glucose Dulbecco’s modified Eagle’s medium containing 10%fetal bovine serum. After that, the cel s were cultured in inducing medium for 3 weeks to differentiate into vascular endothelial cel s.
RESULTS AND CONCLUSION:The rat adipose-derived stem cel s grew as polygonal or fusiform-shaped adherent cel s when cultured in vitro, which could stably proliferate and passage. The rat adipose-derived stem cel s showed very low expression of CD31, a cel surface marker, after passages. After directional differentiations into vascular endothelial cel s, the cel s were pebble-shaped under the inverted microscope. Expression of CD31 was up-regulated, which was much higher in the experimental group than the control group. The induced cel s in the experimental group had stronger abilities than those in the control group to swal ow Dil-labeled acetylated low-density lipoprotein and form tube-like structures on the matrigel after differentiation into vascular endothelial cel s. So, rat adipose-derived stem cel s could be highly successful y induced to differentiate into vascular endothelial cel s in vitro after serum-free culture.

Objective The PRESENT ( Physicians' Routine Evaluation of Safety and Efficacy of NovoMix 30 Therapy) study is a multinational clinical experience program to report the efficacy, safety and acceptability of NovoMix 30 (BlAsp 30) in patients with type 2 diabetes mellitus inadequately controlled with oral antidiabetic drugs (OADs). Methods A total of 4 754 type 2 diabetes patients inadequately controlled with oral antidiabetic drugs were enrolled in the study. All patients were prescribed BIAsp 30 in accordance with the approved labeling. Data were collected at baseline and at the end of 3 months treatment. Results The mean HbA1c, body mass index (BMI), age, and duration were (9.09±1.70)%, (24.30±2.68)kg/m2, (54.63±10.94)years, and (5.46 ±4.17) years separately. The mean daily dose was (0.43±0.14) U/kg at treatment initiation and (0.48±0.15) U/kg after 3 months treatment. After 3 months, the mean HbA1c, fasting plasma glucose (FPG) and postprandial plasma glucose (PPG) were significantly reduced from baseline levels. The mean HbA1c decreased by (2.04± 1.57)%, FPG by a (3.51±2.55)retool/L, and PPG by a (6.51±4.02) mmol/L (all P<0.01). A significant proportion (49.4%) of the patients achieved target HbA1c of ≤7%. The overall rate of hypoglycaemic episodes (events/patient-yr) decreased from 10. 098 at baseline to 3. 810 at study end. The rate of major hypoglycaemia decreased from 0. 787 to 0.126, and the rate of nocturnal hypoglycaemia decreased from 2.356 to 0.547. Compared with previous treatment, more than 99% of the patients and physicians were "satisfied" or "very satisfied" with BIAsp 30 treatment. Conclusions BIAsp 30 was found to be safe and effective to improve the glycaemia control of type 2 diabetes inadequately controlled with OADs in routine clinical practice.

Objective To observe the treatment effect of renal function and blood pressure in patient with blood pressure morning surge.Methods 34 patients take levoamlodipine 2.5 mg/q orally.35 patients take Fosinopril 10 mg/q orally.35 patients take Fosinopril lOmg/q and levoamlodipine 2.5 mg/q orally,continuing 12 months. Blood pressure,urinary albumin excretory rate,scrllm creatinine,urinary creatinine and calculated creatinine clearance at base line were measured.Results Blood pressure (P<0.01) and urinary albumin excretory rate (P<0.01) were decreased by compare to pretherapy in three groups.Post-treatment,urinary albumin excretory rate was reduced from 103.8±44.2 to (84.6±37.5)μg/min in the first group,from 102.9±45.4 to(82.7±38.4)μg/min in the second group,and from 109.8±40.5 to(51.2±40.1)μg/min in the last group.The difference for urinary albumin excretory rate was significant between prior treatment and post-treatment in every group (P<0.05).It is the same between the first group and the second.The difference for urinary albumin excretory rate was significant between the first group and the third group (P<0.01).The difference was significant between the second groud and the third group (P<0.01).Post-treatment,calculated creatinine clearance rate was increased from 84.6±7.4 to 88.2±7.1 in the first group,from 81.4±2.5 to 84.5±4.2 in the second group,and from 79.1±6.8 to 109.6±16.1 in the last group.The difference for calculated creatinine clearance rate was significant between prior treatment and post-treatment in the third group (P<0.01).Conclusion Blood pressure (P<0.01) and urinary albumin excretory rate were decreased by three methods.Three methods all protect renal function,and the third method is the best.

Radioactive 125I interstitial brachytherapy is easy to cause the intestinal tract tissue damage.Its mechanism possibly correlates to the quick renewal speed of the intestinal tract tissue and a majority of ceils in M, G2 and late S phases. The tolerant dose of intestinal tract tissue is approximately 160 Gy. If the absorbed dose is higher than the tolerant one, the intestinal tract tissue will be damaged. In the clinical practice of radio-active 125I interstitial brachytherapy, through the strict plan of the TPS system before the operation, by using ul-trasound, CT, MR/and other imaging technologies in the operating process and establishing the suitable barrier protection between the seeds and intestinal tract tissue, the radioactive damage of the intestinal tract tissue my be reduced.
