Objective To observe the effect of motor relearning program (MRP) on balance function of stroke patients.Methods Sixty stroke patients were randomly divided into the MRP group and control group with 30 cases in each group. The patients of the control group were trained with proprioceptive neuromuscular facilitation (PNF) therapy; those of the MRP group were trained with the MRP therapy. The balance function of all patients was assessed with the Fugl-Meyer Balance Function Assessment before and after training.Results After training, the scores of Fugl-Meyer Assessment of all patients increased ( P<0.05), but scores of the patients of the MRP group were significantly higher than that of the control group ( P<0.05).Conclusion The MRP training can improve the recovery of balance function of stroke patients.

Eleven old male patients with hyperuricemia were collected ( hyperuricemia group,65-90 years old ).10 healthy middle-aged males ( middle-aged group,30-40 years old) and 10 healthy old males ( older group 60-70 years old ) with normal blood uric acid level were used as controls.All of the subjects were given low purine content diet ( 250 mg/d ) for 3 days followed by high purine content diet ( 800 mg/d ) consecutively for another three days.The samples of fasting blood and 24 h urine were collected for assay.The results showed that there were no significant changes of serum uric acid ( UA ) concentration in three groups after low purine content diet.But the levels of serum UA in three groups all increased significantly after high purine content diet,and the change was higher in hyperuricemia group than middle-aged group [ ( 507.7 ± 108.1 vs 378.9 ± 80.1 ) μmol/L,P＜0.05 ].24 h urine uric acid excretion in three groups was all significantly decreased after low purine content diet and increased after high purine content diet.After high purine content diet,24 h urine uric acid was lower in hyperuricemia group than middle-aged group [ ( 2.99 ± 1.21 vs 3.62 ± 1.02 ) mmol/24 h,P＜0.05 ].Blood urea nitrogen levels in all subjects decreased after low purine content diet and increased after high purine content diet ( P＜0.05 or P＜0.01 ).Creatinine clearance rate in hyperuricemia group was decreased after high purine content diet compared with baseline [ (75.3 ± 20.3 vs 80.7 ±20.0) ml/min ],and there were no significant changes in other groups after low and high purine content diet.24 h urine protein in hyperuricemia group was higher than middle-aged group ( P＜0.05 ),and increased after high purine content diet with significant difference ( P＜0.05 ).These results suggest that high purine content diet and decreased by renal uric acid clearance mainly contribute to hyperuricemia in old people.

(8R)-5-O-Methyl-orcinotriol (1) is a new phenolic compound which has never been reported in the literature. Compounds 4-7 showed strong DPPH free radical scavenging activity; whereas compounds 1-7 showed strong ABTS free radical scavenging activity.

OBJECTIVETo investigate the effect of Chinese medicine (CM) Schisandra chinensis on interleukin (IL), glucose metabolism, and pituitary-adrenal and gonadal axis of rats after strenuous navigation and exercise.

METHODSA total of 45 Sprague-Dawley rats were randomized into the quiet control group, the stress group, and the CM group (15 in each group). The CM group received 2.5 g/kg of Schisandra chinensis twice per day for one week before modeling. Except the quiet controls, rats were trained using the Bedford mode for 10 days. On the 11th day, they performed 3 h of stressful experimental navigation and 3 h of strenuous treadmill exercise. The levels of serum testosterone (T), cortisol (CORT), luteinizing hormone (LH), IL-1, IL-2, and IL-6 were tested by radioimmunoassay and enzyme-linked immunosorbent assay, respectively. The adrenal cortex ultrastructure was observed using electron microscopy.

RESULTSCompared with the quiet control group, after navigation and strenuous exercise, blood glucose was increased, and T level was decreased in the stress group (both P<0.01). The blood glucose, CORT, IL-1 and IL-2 levels were significantly reduced in the CM group (P<0.05 or P<0.01) as compared with the stress group. Electron microscopy revealed that the rats in the CM group had a smaller decrease in adrenal intracellular lipid droplets and higher levels of apoptosis than those in the stress group.

CONCLUSIONSSchisandra chinensis can reduce serum CORT and blood glucose levels in stressed rats. It appears to protect the cell structure of the adrenal cortex, and offset the negative effects of psychological stress and strenuous exercise related to immune dysfunction. Schisandra chinensis plays a regulatory role in immune function, and can decrease the influence of stress in rats.

PURPOSE: The characteristic expression of DNA damage response proteins in familial breast cancers with BRCA1, BRCA2, or non-BRCA1/2 mutations has not been analyzed in Chinese patients. Our study aimed to assess the differential expression of microcephalin 1 (BRIT1), ATM serine/threonine kinase (ATM), checkpoint kinase 2 (CHEK2), BRCA1, RAD51 recombinase (RAD51), and poly (ADP-ribose) polymerase 1 (PARP-1) and establish the profile of Chinese familial breast cancers with different mutation status. METHODS: We constructed five tissue microarrays from 183 familial breast cancer patients (31 with BRCA1 mutations; 14 with BRCA2 mutations, and 138 with non-BRCA1/2 mutations). The DNA response and repair markers used for immunohistochemistry analysis included BRIT1, ATM, CHEK2, BRCA1, RAD51, and PARP-1. The expressions of these proteins were analyzed in BRCA1/2 mutated tumors. The association between pathologic characteristics with BRCA1/2 mutation status was also analyzed. RESULTS: In familial breast cancer patients, BRCA1 mutated tumors were more frequent with high nuclear grade, estrogen receptor/progesterone receptor/human epidermal growth factor receptor 2 negative, low Ki-67, and positive CK5/6. BRCA1 mutated tumors had lower CHEK2 and higher cytoplasmic BRIT1 expression than BRCA2 and non-BRCA1/2 mutation tumors. BRCA2-associated tumors showed higher CHEK2 and cytoplasmic RAD51 expression than those in other groups. Nuclear PARP-1 expression in BRCA1/2-associated tumors was significantly higher than in non-BRCA1/2 mutation tumors. Moreover, we found quite a few of negative PARP-1 expression cases in BRCA1/2 mutated groups. CONCLUSION: The clinicopathologic findings of BRCA1-associated Chinese familial breast cancers were similar to the results of other studies. Chinese familial breast cancer patients with BRCA1/2 mutations might have distinctive expression of different DNA damage response proteins. The reduced expression of PARP-1 in Chinese BRCA1/2 mutated breast cancer patients could influence the therapeutic outcome of PARP-1 inhibitors.

In order to fabricate the HLA-DQA1 genotyping chip and develop an integrated, parallel technical platform to type HLA system, a pair of primers and a set of probes were designed according to the sequences of HLA-DQA1 exon 2, where the polymorphism is concentrated. The oligonucleotide chip was made with the methods developed in our laboratory. The target DNA was asymmetrically amplified with the labeled sense primer. The signals were scanned and analyzed after the hybridization between microarray and PCR product. The allele types of the samples were identified. The result was verified by the standard DNA and DNA sequencing. The results showed that the genotyping was successfully carried out in 50 standard DNA samples and 50 clinical samples. Among them, results of the 50 standard DNA samples matched their templates. In the other 50 samples, results of the randomly selected 10 matched their sequencing results except that two of them got the incompletely result. In reproducible tests, the signal reappear rate was 95%. It is concluded that HLA-DQA1 genotyping by using our array system is simple and convenient with satisfied accuracy and reproducibility.
