Circulating tumor cells(CTCs)are essential for establishing recurrence and metastasis in malignant tumors.Detecting CTCs can help for early detection of the cancer metastases and recurrences,and also can help for evaluating prognostic and guiding treatment.CTCs detection technique mainly include screening and separation technology which contains immune magnetic separation technology and reverse transcriptasepolymerase chain reaction and so on.With the development of technique,there is a new technique named ctcchip contains both screening and separation functions.

Objective To study the protective effect of garlicin on radiation injury in mice. Methods Sixty mice were randomly divided into five groups:model control group, solvent control group and garlicin treatment groups[0.17, 0.33, 1.00 g/(kg?d)]. After treated by gavage for 20 consecutive days, the mice were exposed to 60Co-? irradiation for one time and the effect of the irradiation on the amounts of WBC in peripheral blood, the ratio of micronucleus cells in marrow, the content of DNA in marrow cells and the superoxide dismutase (SOD) activity were measured. Results Compared with the exposure group, garlicin increased the amounts of WBC, decreased the micronucleus frequency of marrow cells, increased the content of DNA in marrow cells and increased the SOD activity in mice. Conclusion Garlicin shows a protective effect on irradiation injury in mice.

Objective To observe the influences of valsartan on maintenance of sinus rhythm and left atrial contraction function after cardioversion of permanent atrial fibrillation, and discuss if angiotensin Ⅱ (AT-Ⅱ)receptor blockade could reverse atrial remodeling and remove the basis of permanent atrial fibrillation relapse. Methods Seventy-two patients with permanent atrial fibrillation were divided into control group (36 patients)and valsartan group(36 patients)by random digits table. The two groups were given amiodarone of 200 mg oral once every 8 hours on the eardioversion day. Five days later, the dose was decreased to 200 mg once every 12 hours. And another 5 days later, the dose was again decreased to 200 mg once a day. And 1 month later, the dose was decreased to 100 mg once a day which would be kept for 8 months. On the electrical conversion day and after 8 months, the patients of the two groups were performed echocardiography, and the left atrial dimension(LAD), end diastolic area(EDA), end diastolic volume (EDV), end systolic area(ESA)and end systolic volume(ESV)were compared. Results In 72 patients,59 patients were successful in recovering from sinus rhythm, and duration time was(18±6)h,3 patients were given electrical conversion after 72 h, and 10 patients were directly given electrical conversion and successful. Three patients didn't finish follow-up,and 2 patients died. Sixty-seven patients finished follow-up,among whom 33 patients were in control group and 34 patients were in valsartan group. After followed up for 8 months, 36.4%(12/33)patients recurred in control group, and 17.6%(6/34)patients recurred in valsartan group(P＜0.05).The levels of LAD, EDA, ESA, EDV and ESV in valsartan group were significantly decreased(P＜0.05 or＜0.01), but they showed no significantly difference in control group(P ＞ 0.05). The systolic pressure and diastolic pressure decreased in two groups, but there were no significant difference (P＞0.05). Conclusion Valsartan combines with amiodarone is superior to amiodarone in maintaining sinus rhythm and improving left atrial contraction function after cardioversion of permanent atrial fibrillation.

This study investigated the role of glucose in the biogenesis of high-density lipoprotein cholesterol (HDL-C). Mouse primary peritoneal macrophages were harvested and maintained in Dulbecco's modified Eagle's medium (DMEM) containing glucose of various concentrations. The cells were divided into 3 groups in terms of different glucose concentrations in the cultures: Control group (5.6 mmol/L glucose), high glucose concentration groups (16.7 mmol/L and 30 mmol/L glucose). ATP-binding cassette transporter A1 (ABCA1) mRNA expression in the macrophages was detected by semi-quantitative RT-PCR 24, 48 and 72 h after glucose treatment. The results showed that ABCA1 mRNA expression in the 16.7 mmol/L glucose group was not significantly different from that in the control group at all testing time points (P>0.05 for each). In the 30 mmol/L glucose group, macrophage ABCA1 mRNA expression was not changed significantly at 24 h (P=0.14), but was substantially decreased by 40.4% at 48 h (P=0.009) and by 48.1% at 72 h (P=0.015) as compared with that in the control group. It was concluded that ABCA1 is of vital importance for HDL-C biogenesis. High glucose may hamper HDL-C biogenesis by decreasing ABCA1 expression, which contributes to low HDL-C level in diabetes.

ObjectiveTo compare the clinical results of small surgical incision of bilateral spinous process and traditional open surgical incision in posterior single level lumbar interbody fusion,and assess the application value of the small surgical incision of bilateral spinous process in posterior single level lumbar interbody fusion.MethodsFrom December 2006 to June 2008,70 patients with lower lumbar vertebral diseases underwent single segment posterior lumbar interbody fusion.Patients were randomly divided into small surgical incision of bilateral spinous process group(Hereinafter referred to as small incision group) of 36 cases and 34 cases of conventional open group.Small incision group included 20 males and 16 females with an average age of 52.0 years.Traditional open group included 16 males and 18 females with an average age of 53.2 years.Two groups of operative time,blood loss,postoperative drainage,X-ray projection operation frequency,hospital stay,complication rate,creatine phosphokinase (CPK) level,multifidus cross-sectional area,postoperative low back pain visual analogue scale(VAS),Oswestry disability index(ODI),interbody fusion rate were compared,respectively.ResultsAll of 70 cases were followed up for 12-24 months (average,16).There were no statistically differences in the operation time,the number of X-ray projection,complication rate,and fusion rate between the two groups (P＞0.05),but there were significant differences in blood loss,postoperative drainage,the first day and the third day of postoperative the level of CPK,postoperative multifidus muscle cross-sectional area,postoperative low back pain VAS,hospital stay,and postoperative ODI between the two groups(P＜0.05).ConclusionSmall surgical incision of bilateral spinous process and traditional open surgical posterior lumbar interbody fusion were satisfied with the efficacy,but small surgical incision of bilateral spinous process with less trauma,shorter hospital stay,and rapid postoperative recovery.

Objective To establish an accurate method for estimating the indoor gamma dose rate from decorative stones.Methods Combining a room model with decorating conditions,the gamma dose rates and dose rate conversion factors (DCF) at 1 m above the floor in the room center were calculated with the Monte Carlo simulations,and the calculation results were verified through experiments.Based on the results,the limit of radionuclide contents in stone materials was further discussed.Results The DCF increases with the increase of area or thickness of decorative stones in the same room.The increase of DCF with the thickness of decorative stone is approximately linear.The DCF also increases with the area of decorative stones,but the increasing trend slows down.For the same decorative stones,the smaller the room,the larger the increase of gamma dose rate.Experimental results were consistent with the simulation results within ± 20％.Conclusions The increase of indoor gamma dose rate depends not only on the radionuclide contents,but also on the area and thickness of the decorative stones as well as the room size.The method used in this study can be used to estimate,more accurately than ever,the additional external exposure to residents due to decorative stones,and it provides a theoretical basis for revising the limit standard on radionuclide contents in decorative materials.
