Objective To study the effects of allopurinol in different dose on the cardiac function of chronic heart failure rats induced by adrimycin. To explore dose-dependency of allopurinol in improving blood vessel endothe-lium function and cardiac ventricle remodeling of the rats heart, as to supply evidence and new sight in clinical treat-ment of congestive heart failure. Methods 40 Sprague-Dawley male rats were randomly divided into four groups: normal control group (group A)、model control group (group B)、low-dose allopurinol group (group C)、high-dose allopurinol group (group D). The heart failure model was made by administering adriamycin to rats. After the model myocardial pathological changes were detected. Results Compared with the normal control group, the weight and heart weight of rats in model control group and allopurinol groups were obviously lessen (group A=(300.10± 9.85)g,group B=(200.67±9.91)g, group C=(233.14±9.42)g,group D=(248.25±13.34) g;group A= (828.30±50.97) nag, group B=(681.50±16.97) mg, group C=(743.00±17.20) nag, group D=(784.88± 36.83) mg,P<0.05). Heart weight indexes were all incerased ( group A=(2.76±0.15) mg/g, group B=(3.41± 0.17) mg/g, group C=(3.26±0.76) mg/g, group D=(3.11±0.65) mg/g, P<0.05). The hemedynamics resuh showed that myocardial contractile force were enhanced in drug groups. The level of NO, SOD were increased in the allopurinol groups compared with the model control group (group B: NO=(41.55±6.28) μmol/L, group C: NO= (52.47±5.59) μmoL/L,group D:NO=(61.04±4.26) μmoL/L; group B:SOD=(63.83±6.40) U/ml,group C: SOD=(76.29±7.99) U/ml, group D: SOD=(100.13±7.43) U/ml, P<0.05) and MDA levels were obviously decreased (group B: MDA=(9.70±1.08) μmol/L, group C: MDA=(6.64±0.34) μmol/L, group D: MDA= (5.72±0.71)p.moVL,P<0.05). The level of NO, SOD were obviously increased in the allopurinol of high-dose group compared with low-dose allopurinol group(P<0.05). MDA levels were obviously decreased(P<0.05). The myocardial pathological changes were relieved obviously in the allopufinol groups. Conclusion Allopurinol improves blood vessel endothelium function dose-dependently. High-dese allopurinol obviously decreases MDA, improve NO, SOD, thereby can improve the cardiac function of heart failure.

Objective To investigate the effect of transcutaneous electrical nerve stimulation (TENS) on baseline eyes-closed brain activation and on pain-related EEG activity when TENS is applied contralatarally to the hand of pain. Method 128-channel electroencephalography (EEG) was recorded in four conditions including baseline,heat pain test,TENS stimulation and contralateral TENS modulation in 15 right-handed healthy young males. The Short Form McGill Pain Questionnaire was employed to assess pain sensation. Fast Fourier Transformation analysis (FFT) was performed to calculate absolute EEG power spectra based on 7 bands spectrum. Results ① The fronto-central beta-1 activity was significantly enhanced by TENS compared to eyes-closed [eyes-closed:(290±201)μV2,TENS:(385±224)μV2,t=3.323,P<0.01].②TENS markedly relived pain sensation assessed by SF-MPQ and significantly increased the posterior-anterior alpha-1 power [pain:(332±221)μV2,TENS modulation:(378±243)μV2,t=3.683,P<0.01] and fronto-central and posterior beta-1 activities [pain:(348±213)μV2,TENS modulation:(397±240)μV2,t=2.362,P<0.05]. Conclusion TENS,used as a peripheral nerve stimulation,mainly activates sensorimotor cortex.The increased Alpha-1 activity implies that TENS is likely able to relieve pain affective.

The design and efficacy of surgery for horizontal idiopathic nystagmus (HIN) with abnormal head posture and strabismus were investigated. Different surgical procedures were selected according to the angle of head turn in 44 cases of HIN with abnormal head posture and strabismus. For patients with a head turn of 15° or less, the Anderson procedure was used; the yoke muscles were recessed upon slow-phase. For patients with a head turn between 15° and 25°, the surgery was designed as a Kestenbaum 5-4-4-5 procedure. For patients with a head turn of 25° or more, the surgery was designed as a Parks 5-8-6-7 procedure. The surgery to correct the abnormal head posture was performed on the fixating eye while that to correct the deviation was then performed on the non-fixating eye at the same time. The amount of surgery of the horizontal rectus muscles on the non-fixating eye was sum of the angle of head turn and the degree of deviation, which was calculated as follows: recession/resection amount of medial and lateral rectis/2×5=angle of head turn±degree of deviation. The results showed as follows: (1) Visual acuity: the visual acuity in the primary ocular position increased two lines or more in 35 patients, accounting for 79.55%. Nine patients had no or only one-line improvement, accounting for 20.45% of the entire study population; (2) The degree of deviation in the primary ocular position: 37 cases had a normal primary ocular position or the degree of deviation ≤8(δ) after surgery, accounting for 84.09%. Six patients had a residual degree of deviation of 8(δ)-15(δ), accounting for 13.64%. One patient had a residual degree of deviation >20(δ), accounting for 2.27% of the patients examined; (3) Abnormal head posture: 34 patients had a normal head posture or a head turn of less than 5°, accounting for 72.27%. Eight patients had a residual head turn of 5°-15°, accounting for 18.18%. Two patients had a head turn of 15°-25°, accounting for 4.55%. It was concluded that different surgical procedures based on the angle of head turn and the relationship between deviation and null zone can eliminate anomalous head posture, correct deviation, and improve vision acuity in the primary ocular position.

Objective To examine the role of SPHK-1/S1P and NFκB p65 signal pathway in non-small cell lung cancer (NSCLC)drug-resistant cells.Methods The drug-resistant cell line of lung cancer H460/DDP was constructed and its biological characteristics were identified successfully.The expression of SPHK-l was tested by RT-PCR and Western blot methods.S1 P and some proteins related to NFκB pathway were studied by Western blot. Results The drug-resistant lung cancer cell line H460/DDP was constructed and its drug-resistant ability was evaluated (IC50H460/DDP = 50.62μg/mL, RIH460/DDP = 2.95 ). Cisplatin at a concentration of 10 - 80 μg/mL significantly decreased cell death of drug-resistant cell line (P<0 .01 ).Western blot assay analysis showed that overexpressions of SPHK-l,S1 P and NFκB p65 were significantly higher in drug-resistant cell line than in their parent cell line H460 (P=0.0415,P=0.0465,P=0.0218).RT-PCR method revealed that SPHK-1 mRNA was overexpressed in drug-resistant cell line compared with that in their parent cell line H460 (P<0.05).More NFκB p65 protein in cell nucleus was expressed in drug-resistant cells than in parent cells.Conclusion SPHK-1/S1P and NFκB p65 signal pathway may play an improtant role in the drug-resistant H460 cell line in non-small cell lung cancer.
