Objective To observe the influence of telephone follow-up and home follow-up on compliance behavior and activities of daily living (ADL) of stroke patients during rehabilitation. Methods 50 cases were as telephone follow-up group and 50 cases were as home follow-up group extracted from 355 stroke patients who discharged the hospital during August 1, 2010 to July 1, 2012. They were followed up 2 weeks, 1 month and 3 months after discharge respectively. Their ADL were assessed with Bathel index (BI) at discharge and 3 months after discharge, and the compliance behavior were assessed 3 months after discharge. Results There was no significant difference in the score of BI between 2 groups at discharge (P>0.05), and the score of BI improved in both groups 3 months after discharge (P<0.05), but it was higher in the home follow-up group than in the telephone follow-up group (P<0.05), as well as the rate of compliance behavior (P<0.01). Conclusion Regular home follow-up can improve the compliance behavior of stroke patients during rehabilitation.

Genomic instability is one of the most pervasive characteristics of cancer cells,and DNA damage response (DDR) pathway plays a crucial role in genomic stability.The DDR pathway is a complex signaling network,which involves cell DNA repair,apoptosis and cell cycle regulation.Deficiencies in these repair pathways can result in several different genetic disorders,including cancer.Targeted therapy based on inhibiting the DDR pathway in cancers offers a novel therapy strategy for patients with tumors lacking specific DDR functions.Many small-mole-cule compounds targeting DDR pathway are typically developed for solid cancer therapy.The poly (ADP-ribose) polymerase (PARP) inhibitor is a kind of DDR inhibitors which exploits the principle of synthetic lethality to selectively kill cancer cells.This review highlights the molecular mechanisms of PARP inhibitor action,the progress of PARP inhibitors in cancer therapy,drug resistance and the challenge of PARP inhibitor in the future.

Objective To investigate the role of norepinephrine in the down-regulated visceral sensitivity of rats deprived of rapid eye movement(REM)sleep.Methods Twenty-four male Sprague- Dawley rats were randomly divided into 3 groups:cage-yoked rats as control(YC),rats with REM sleep deprivation(SD)and rats with yohimbine administered intraperitoneally after REM sleep deprivation(YSD).Flower pot technique was employed to make sleep deprivation model.YSD group was given vohimbine intraperitoneally at the 48th hour after REM sleep deprivation.After both SD and YSD groups had completed these processes,rats of all the three groups were given colorectal distension(CRD)and electromyogram (EMG)was recorded at the same time.The number of discharges of EMG and the threshold of Dain perception of the rats were observed to evaluate the visceral sensitivity.The thalamus,rectum and distal colon were taken after CRD;MAO-mRNA and TH-mRNA in three tissues were detected with RT-PCR.Resuits On 48th hour,the number of discharges of EMG in 10 seconds responding to CRD in group SD was significantly less than that in group YC and the threshold of pain perception in group SD was higher than that in group YC(P<0.05).The number of discharge of EMG in group YSD was significantly more than that in group SD(P<0.05).The expression of MAO-mRNA in group SD was lower than that in group YC(P<0.05)and the expression of TH-mRNA in group SD was higher than that in group YC(P< 0.05).Conclusions The visceral sensitivity in rats is down-regulated by REM sleep deprivation,which can increase synthesis of norepinephrine.Norepinephrine can modulate visceral sensitivity.

Objective To establish a new traceability pathway of point-of-care testing ( POCT ) of HBA1c by using commutable quality controls, in order to improve the accuracy of POCT HBA1c and the harmonization of testing results with those of central laboratories.Methods The study was about measurement traceability. Human frozen whole blood samples with IFCC assigned values were used to calibrate the G8 HBA1c Variant in June, 2013.According to the CLSI EP9-A2-IR guideline, 50 patient samples and 2-level commercial QC samples were then analyzed by G8 system and DCA Ventage system.The best fitting curves for fresh patient samples and the commercial QC materials were established separately. The patient results tested on the DCA Ventage were modified and verified.Paired t-test and Passing Bablok linear regression were used.Results The linear equation of DCA/G8 before calibration was Y=0.899 5X+0.389 1(R2 =0.991 0).Calibration by fresh patient samples reduced the mean bias of DCA/G8 from -0.40%±0.34%to 0.00%±0.29%.Calibration by QCs reduced the mean bias to 0.15%±0.29%.The linear correlation established by quality controls was stable, which made the bias was lower between DCA and G8 in the consequent six runs.Conclusions The accuracy and the traceability of POC testing could be realized by using commutable QC materials traceable to IFCC assigned values.Through this method, POC testing can become more comparable to the results of clinical laboratory HBA1c instruments.
