Genomics, Proteomics & Bioinformatics 2008;6(3-4):186-189
We developed an R function named "microarray outlier filter" (MOF) to assist in the identification of failed arrays. In sorting a group of similar arrays by the likelihood of failure, two statistical indices were employed: the correlation coefficient and the percentage of outlier spots. MOF can be used to monitor the quality of microarray data for both trouble shooting, and to eliminate bad datasets from downstream analysis. The function is freely avaliable at http://www.wriwindber.org/applications/mof/.

OBJECTIVETo observe the effects of electroacupuncture (EA) on circadian rhythm of temperature and melatonin (MT) in depression rats model induced by chronic stress, so as to explore the biological mechanism of EA for depression.
METHODSTwenty-four SD rats were randomly divided into a control group, a model group and an EA group, 8 cases in each one. Rats in the control group were treated with normal diet for 21 days without any treatment. In the model and EA group, rat model was established by chronic unpredictable stress combined with solitarily feeding method, and rats in the EA group was treated with EA at "Baihui" (GV 20), "Yintang" (GV 29) 1 h before stress stimulation everyday, 2 Hz in frequency and intensity was favorable with the head of rat slightly shivering. The needles were retained for 20 min, once a day for totally 21 days. After EA treatment, open-field experiment was adopted to observe the behavioral improvement; the rats temperatures were monitored at six time points (2:00, 6:00, 10:00, 14:00, 18:00, 22:00) and orbital blood sampling was collected. The level of serum MT was tested by enzyme linked immunosorbent assay. The circadian rhythm changes of temperature and serum MT in each group were compared.
RESULTSThe numbers of horizontal movement and vertical movement in the model group were obviously lower than those in the control group (both P < 0.05), while those in the EA group were significantly improved compared with those in the model group (both P < 0.01). The circadian rhythm of temperature and MT disappeared in the model group, which was improved into normal level after EA treatment.
CONCLUSIONThe electroacupuncture has regulation effects on circadian rhythm of temperature and melatonin in depression rat model induced by chronic stress.

OBJECTIVETo observe the change of urinary monocyte chemottractant protein-1 (MCP-1) in patients with diabetic nephropathy (DN), and to explore the therapeutic effect and mechanism of triptolide (TL) in treating DN.
METHODSThirty-five patients in the treated group were treated with TL plus benazepril and thirty two patients in the control group were treated with benazepril alone for six months. The change of urinary MCP-1 was measured before and after treatment.
RESULTSLevel of urinary MCP-1 in DN patients was significantly higher than that in healthy subjects (P < 0.01), but it could be significantly decreased after TL treatment, showing significant difference as compared with that in the control group (P < 0.05).
CONCLUSIONDetermination of urinary MCP-1 level is beneficial to know the degree of kidney inflammation in DN patients. TL can inhibit inflammatory reaction to decrease the level of urinary MCP-1, and thus improve the renal function.

EMG, This paper introduces a slope variability algorithm which uses the CU Database and the AHA Database. The sensitivity, specificity, positive predictivity and accuracy are calculated and these values are compared with the results from two earlier detection algorithms. The results show this algorithm is more effective and fast than other algorithms.

A method based on wavelet transform has been developed for detecting QRS-waves.The MIT-BIH database is used to evaluate this method, and the accuracy is over 99.5%. Then the method is implanted into the embedded system to implement the real-time detection of ECG. This method has good performances in time-delay and computation.

A kind of real-time remote monitoring embedded terminal which is combined with mobile communication technology and GPS localization technology, has been developed. The results of preliminary experiments show that the terminal can transmit ECG signals and localization information in real time and continuously, supply a real-time monitoring of out-of-hospital cardiac patients and trace the patients.

OBJECTIVETo examine the effect of particulate matter (PM) less than 10 microns in diameter (PM10) and ozone (O3) on daily mortality in Shanghai, China.
METHODSA generalized additive model with penalized spline function was used to observe the acute effect of PM10 and O3 on daily mortality.
RESULTSHigher PM10 significantly increased the effect of O3 on total mortality, and O3 also increased the effect of PM10 although the estimated increment was statistically insignificant.
CONCLUSIONOur findings provide further evidence for the effect of PM10 and O3 on daily mortality.

OBJECTIVETo compare clinical outcomes of superior labrum from anterior to posterior (SLAP) repair and biceps tenodesis in treating type I SLAP injury.
METHODSFrom March 2009 to March 2012, 38 patients with type II SLAP injury were treated with SLAP repair and biceps tenodesis, and all patients were unilateral SLAP injury. Sixteen patients treated with biceps tenodesis included 8 males and 7 females with an average age of (49.3±3.7) years old (ranged, 45 to 54); 10 cases were on the left side and 6 cases on the right side; 10 cases were caused by falling down, 2 cases were caused by throwing damage and 4 cases were caused by daily life damage; the time from injury to operation were from 3 to 8 weeks. Twenty-two patients treated with SLAP repair included 14 males and 8 females with an average age of (49.0±2.8) years old (ranged, 44 to 56); 13 cases were on the left side and 9 cases were on the right side; 14 cases were caused by falling down, 5 cases were caused by throwing damage and 3 cases were caused by daily life damage; the time from injury to operation were from 3 to 7 weeks. Preoperative, postoperative at 6 months, 1 year and 2 years' UCLA and SST score were compared between two groups.
RESULTSThere was no significant differences in UCLA and SST score between two groups before operation. At 6 months after operation, UCLA and SST score in biceps tenodesis group was higher than SLAP group, and action,range of anteflexion, strength of anteflexion, degree of satisfaction in biceps tenodesis group was higher than SLAP group. There was no significant meaning in SST and UCLA score between two groups at 1 and 2 years after operation.
CONCLUSIONShort-term efficacy of biceps tenodesis for SLAP injury is better than SLAP repair, but long-term efficacy is fairly.
