BACKGROUND:Separating umbilical cord blood stem cells using tubes has low efficiency,and microbial contamination easily occurs during this process,therefore,safety cannot be ensured in clinical application.lt is urgent to find a method for separating umbilical cord blood stem cells to treat femoral head necrosis.OBJECTIVE:To establish a high efficient,safe,and clinically valuable method to separate umbilical cord blood stem cells.DESIGN,TIME AND SETTING:A self-control experiment was performed at the First Department of Surgery,Zhengzhou Second People's Hospital,Institute of Blood Constituent Application,Henan Red Cross Blood Centre between February 2006 and August 2007.PARTICIPANTS:Eight male patients with femoral head necrosis,averaging 40.6 years of age,were included in this study.Of these patients,4 had the history of hormone application.An average of 90 mL umbilical cord blood was harvested from each healthy normal full term neonate from Maternal and Children Health Care Hospital of Zhengzhou City.The quadruple bags used for separating umbilical cord blood stem cells consisted of 1 main bag,1 empty bag,and 2 physiological saline bags,provided by Shandong Weigao Holding,China.METHODS:Within 6 hours after collection,umbilical cord blood was centrifuged in the empty bag of quadruple bag,which was connected with an aseptic filling machine.After centrifugation,partial blood plasma was discarded,and the remaining erythrocytes were thoroughly mixed by adding hetastarch.Five minutes later,the mixture was diluted with physical saline at 1:1.Umbilical cord blood was slowly added into the main bag (at 1:1),in which,human lymphocyte separating medium was pre-added.After cantrifugation,the upper layer of solution,i.e.,monocyte-rich solution,was transferred into another empty bag.Within 24hours of preservation,after suspension with umbilical blood plasma,umbilical cord monocytes were transfused into patients with femoral head necrosis via superficial vein on the hand back,monocytes≥1×108/portion,2 portions once.There were three treatment courses,each involving three transfusion sessions,one session every 4 days,and a 2-3-month interval between two treatment courses.MAIN OUTCOME MEASURES:Cell recovery rate and cell viability of umbilical cord blood monocytes and improvements in clinical symptoms.RESULTS:The separation of quadruple bags could obtain umbilical cord blood monocytes with high recovery rate.Furthermore,microbial contamination hardly occurred in the process of separation.Hip joint pain relieved or disappeared to different extents in all 8 patients,with an effective rate of 100%.Abduction and internal rotation of hip joint,ambulation distance,and gait were markedly improved.At 6 months after cell transplantation,5 patients presented with changed bone density in femoral head necrosis regions,2 showed normal femoral head morphology,and the remaining 1 exhibited no obvious changes.Joint effusion was reduced or disappeared in 12 hips.Magnetic resonance images showed that femoral head morphology had been improved in various degrees in 9 hips,but no changes in 3 hips.No complications,fever,or allergies occurred during and after cell transplantation.CONCLUSION:The method of separating stem cells from umbilical cord blood in junction with aseptic interface technology is highly effective,safe,and clinically valuable.Multiple intravenous transfusions of umbilical cord blood stem cells provide a novel approach for systemic treatment of femoral head necrosis.

OBJECTIVETo analyze the electrical activity property changes in nucleus accumbens (NAc) of heroin-induced conditioned place preference (CPP) rats during different stages of heroin dependence and to explore NAc's roles in the formation of drug dependence.

METHODSRecording electrodes were bilaterally embedded into the NAcs of rats with the aid of stereotaxic apparatus, followed by establishment of heroin-dependent rat model. The NAc electrical activity during 3 different stages of heroin dependence, including heroin pre-exposure, immediate post-exposure and heroin withdrawal, were respectively recorded using EEG wireless telemetry techniques. The frequency distribution (ranging from 0.5 to 30 Hz) and the amplitude of NAc electrical activity were analyzed and measured.

RESULTSHeroin-dependent rat models were successfully established and their withdrawal symptoms were evident. All rats showed a conditioned place preference (CPP) for the white box after 5-10 days of heroin-exposure, and displayed a maximum withdrawal symptoms on 2d after heroin- withdrawal. During all statges of heroin-dependence, the NAc electrical activity contained the highest proportion of delta rhythm and the lowest proportion of alpha2 rhythm. The discharge frequence band was similar across different stages. There was a significantly increased ratio of low-frequency discharges (delta rhythm) and decreased ratio of high-frequency discharges (beta rhythm) in NAc of rats during the immediate post- heroin exposure stage when compared with that during pre-exposure and heroin withdrawal stages. During the withdrawal stage, the ratio of at rhythm was significantly lower than during pre- and post-heroin exposure stages (P < 0.01). Further, the mean discharge amplitude in NAcs during immediate post-exposure and withdrawal stages was significantly increased relative to pre-exposure stage. However, the mean discharge amplitude during heroin withdrawal stage was significantly lower than during immediate post-exposure stage.

CONCLUSIONThe electrical activity properties in rat NAcs showed a significant change during different stages of heroin-dependence, which suggested that neuronal activities in NAcs might contribute to the modulation of drug-dependence.

OBJECTIVETo explore therapeutic effect and action mechanism of regulating spleen-stomach needling on diabetic nephropathy (DN).

METHODSUsing multi-centric, randomized, controlled and blind principles, 144 cases of DN were divided into an observation group and a control group according to random digital tab, 72 cases in each one. Based on regular treatment of diabetes, the regulating spleen-stomach needling was applied at Zhongwan (CV 12), Quchi (LI 11), Hegu (LI 4) and Xuehai (SP 10), etc. in the observation group while Shenshu (BL 23), Taixi (KI 3), Sanyinjiao (SP 6), Yanglingquan (GB 34), etc. were selected in the control group by reference of Acupuncture and moxibustion. The treatment was given twice a day, six days as a treatment session with interval of one day between sessions. Totally six weeks were required. Changes of clinical symptoms and signs, fast blood glucose (FBG), urinary albumin excretion rate (UAER), beta2-microglobulin (beta2-MG), monocyte chemotactic protein-1 (MCP-1), lymphocyte membrane cholesterol, propanediol (MDA), PCO, 8-hydroxydeoxy guanosine (8-OHdG), superoxide dismutase (SOD), CD3+, CD4+, CD8+, and CD4+/CD8+ were observed before and after treatment in two groups.

RESULTSAs for improving clinical symptoms and signs, total effective rate was 84.29% (59/70) in the observation group and 55.56% (40/72) in the control group, which had statistical difference between two groups (P<0.01). As for regulating glycometabolism [(6.25 +/- 0.32) mmol/L vs (8.09 +/- 0.63) mmol/L], reducing UAER [(154.43 +/- 55.14) mg/24h vs (268.91 +/- 77.65) mg/24h], restraining over-expression of MCP-1 [(137.59 +/- 36.15) pg/mL vs (166.89 +/- 42.82) pg/mL], regulating level of oxidative stress, prohibiting oxidation of protein and adjusting quantity and activity of T lymphocyte subgroup, the observation group was superior to the control group (P< 0.05, P<0.01).

CONCLUSIONThe regulating spleen-stomach needling is an effective method for treatment of DN, which cold improve glycometabolism disturbance-induced progressive kidney injury, recover glomerular filtration, reduce urinary albumin excretion rate, restrain overexpression of MCP-1, adjust level of oxidative stress, prohibit oxidation of protein, increase protectiveness of membrane, adjust quantity and activity abnormity of T lymphocyte subgroup, leading to repairing lymphocyte damage and improving immune expression to delay kidney damage.

Objective To explore the relationship of methylenetetrahydrofolate reductase (MTHFR)gene C677T,factor V(FV)gene G1691A and prothrombin(PT)gene G20210A polymorphisms to unexplained recurrent early spontaneous abortion(URESA).Methods One hundred and twelve patients with URESA and 100 women with at least 1 normal pregnancy and without any miscarriage were analyzed for MTHFR,FV and PT gene polymorphisms by polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP).Results MTHFR gene T/T genotype and T allele frequencies were increased in URESA patients[38.4%(43/112)and 59.8%(134/224)]versus controls[18.0%(18/100)and 43%(43/100),P

Objective:A new algorithm based on Hough transform (HT) was proposed to improve the accuracy and stability of the film image analysis of Automatic Quality Assurance (AQA) test, and to explore the influence of the resolution of film image on the test results.Methods:Nine pairs of films were obtained for AQA modules in this study. Firstly, the median filter was used to preprocess the grayed-out film image to remove noise interference. Then, a global threshold was utilized to binarize the image. The images were edge-detected and the film edge line was extracted by Hough transform. The film image was transformed to the correct position. Finally, the edge of the field shadow circle and the shadow circle of the tungsten ball were extracted by the edge detection method and Hough transform. The radial error was finally obtained by analyzing the concentricity.Results:There was no significant difference in the accuracy between the test results yielded by the HT method and the AQA software ( P>0.05). The difference in the standard deviation of the test results was statistically significant ( P=0.027), indicating that the algorithm increased the stability while ensuring the accuracy of film analysis. Increasing the resolution of film scanning failed to significantly improve the accuracy and stability of film analysis in both two methods. Conclusions:The algorithm used in this study can eliminate the human error caused by film scanning placement while ensuring the accuracy of film analysis, providing a more stable way for the AQA test of the CyberKnife system.
