Objective To investigate the effectiveness of cis-diamminedichloroplatinum (DDP) combined with hyperthennia in killing liver tumor cells and its influence on erythrocytes in vitro. Methods Cultured liver tumor cells (2 ml) were mixed with erythrocyte suspension (10 ml) and then the mixture was separated into 6 centrifuge tubes with 2 ml in each one. The centrifuge tubes were randomly divided into A-F groups and the experiment was repeated for 30 times. Normal saline 2 ml was added in A and D groups. DDP 2 ml (200 μg/ml) was added in B and E groups. DDP 2 ml (400 μg/ml) was added in C and F groups. The cells were then incubated in warm bath of 37 ℃ for 30 min in A, B and C groups and in warm bath of 42 ℃ for 30 min in the other three groups.After hyperthermic treatment, tumor cells were isolated from erythrocytes using density gradient centrifugation, the inhibition rate of tumor cells was determined by MTT method and the clone formation of tumor cells was checked.The erythrocyte osmotic fragility and content of 2,3-diphosphoglyceric acid in erythrocytes were measured. Results The inhibition rate of tumor cells was gradually increased, while the rate of tumor cell clone formation decreased with the increase in the temperature and DDP concentrations ( P < 0.01) . The rate of tumor cell clone formation was more than 98% and no clone formation was tested in group F. There was no significant difference in the content of 2,3-diphosphoglyceric acid in erythrocytes between before and after hyperthermic treatment in group F ( P >0.05 ) . The rate of hemolysis of erythrocytes was less than 1 % in the 0.68 % sodium chloride solution in group F.Conclusion DDP 200 μg/ml combined with hyperthermic treatment with temperature of 42 ℃ for 30 min can make the liver tumor cells lose the capability of proliferation, however, it exerts slight effect on erythrocyte membrane and no influence on the oxygen-carrying capacity of erythrocytes.

BACKGROUND:Core training has been gradual y accepted worldwide.“Core”is only a generalized perception, and how to define the muscles, the difference among the muscles and the mode of the muscle recruitment consist of the important part of research work on core training.
OBJECTIVE:From the aspects of theoretical basis, the development of training methods and measurement of training effectiveness, to elaborate the method issues and new insights on core stability training.
METHODS:PubMed, ScienceDirect and CNKI databases were searched by the keywords of“core training, core exercise, core strength”in the titles and abstract to retrieve relevant articles published from 1979 to 2013.
RESULTS AND CONCLUSION:The neural subsystem was first reported by Panjabi to monitor the various signals from the transducers and direct the active subsystem to provide the needed stability. Neutral zone is regarded as an important clinical indicator relevant to spinal stability. Spinal injury and muscle weakening can result in spinal instability and even low back pain and peripheral pain. Core trainings include Swiss bal , plank exercise, sling exercise and so on. Up to now, research on core training is focusing on its mechanism. Core stability training is not only defined as torso stability training, but also refined to the stability training of each joint.

ObjectiveTo observe the effects of catalpol, the effective component of Rehmanniae Radix, on atrionector cell apoptosis andβ-tubulin in vitro rabbit injured by simulated ischemia reperfusion;To explore the mechanism of treating sick sinus syndrome.MethodsAtrionector cells were collected from newborn rabbits. Cells were divided into 5 groups:normal group, model group, catalpol high, medium and low dose groups. Anoxia and aglycaemia were established to simulate ischemia. Atrionector cellular damage models were established by recovering the supply of oxygen and sugar. Normal control group and model group were given the same volume of culture medium, while catalpol high, medium and low dose groups were given medicine with relevant concentrations (100, 20, 10μg/mL, respectively). ELISA, FCM, laser scanning confocal microscopy were used to observe apoptosis rate andβ-tubulin of atrionector in each group.Results Apoptosis rate of the model group was obviously higher than the normal group (P<0.01), andβ-tubulin cleavage was obvious. Apoptosis rate in catalpol high, medium and low dose groups were significantly lower than that of the model group (P<0.01);β-tubulin structure were significantly more complete compared with the model group;the fluorescence intensity was significantly higher than that of model group (P<0.01).Conclusion Catalpol can inhibit atrionector cellular apoptosis caused by simulated ischemia reperfusion. Its protective effects on atrionectorβ-tubulin may be the mechanism of the treatment of Rehmanniae Radix for sick sinus syndrome.

Objective To observe the effects of ferulic acid on cell apoptosis andβ-tubulinin vitro of rabbit sinoatrial node injured by hypoxia and low glucose, and to explore its mechanism.Methods Model cells were established on sinoatrial node cells from newborn rabbit by performing deprivation of oxygen and glucose. Then the model cells were divided into 5 groups: a normal control group, a model group, ferulic acid high, medium and low dose group. The normal control group and the model group were treated with equal volume of culture medium, and the three volume ferulic acid groups were treated with ferulic acid of 100, 20, and 10μg/ml respectively. Flow cytometry, laser scanning confocal microscopy were used to observe the sinoatrial node apoptosis rate and cytoskeleton proteinβ-tubulin in each group.Results Apoptosis rate of the model group was obviously higher than the normal group (56.95% ± 11.99%vs. 31.45% ± 6.32%,P<0.01), whileβ-tubulin cleavage was significantly lower than the normal group (5.141 ± 0.218vs. 8.035 ± 0.762,P<0.01). Apoptosis rate of ferulic acid high, medium dose group were significantly lower than the model group (24.85% ± 6.34%, 26.70% ± 9.84%vs. 56.95% ± 11.99%,P<0.01),β-tubulin structure were significantly more complete compared with the model group (7.927 ± 0.357, 5.961 ± 0.351vs. 5.141 ± 0.218,P<0.01).Conclusions Ferulic acid can suppress apoptosis of sinoatrial node cells caused by low glucose and oxygen. Protecting the sinoatrial node cell skeleton protein ofβ-tubulin may be one of the mechanisms.

BACKGROUND:The choice of schwannoma resection is strongly associated with whether the tumor was completely resected, whether stretch during resection injures spinal nerves, and final y with the prognosis of treatment.
OBJECTIVE:To evaluate the spinal stabilization after laminectomy combining unilateral or bilateral nail-rod system for schwannoma in the spinal canal or intervertebral foramen.
METHODS:A total of 48 cases of schwannoma in the spinal canal or intervertebral foramen of neck, chest and waist underwent laminectomy combining unilateral or bilateral nail-rod system. 34 cases in spinal canal received bilateral nail-rod system, and 14 cases in the intervertebral foramen received unilateral nail-rod system.
RESULTS AND CONCLUSION:At 3 days and 3, 6, 12 months after internal fixation, radiograph results demonstrated that location of implants was good. Bone graft fusion was found. No spinal instability and vertebral slippage occurred. Neural functional score Bodford (1997) and quality of life score were significantly increased after treatment (P<0.01). Muscle strength assessed by Lovett grade was significantly elevated after treatment (P<0.01). Pain evaluated by Virtual Rescan grade was significantly lessened after treatment (P<0.01). Schwannoma was completely resected in 48 patients. After treatment, six patients affected leakage of cerebrospinal fluid. One case experienced infection of cerebrospinal fluid. One case had to undergo secondary operation due to the infection. Three cases received nerve root resection due to tumor erosion. These experimental results confirmed that laminectomy combining unilateral or bilateral nail-rod system for schwannoma in the spinal canal or intervertebral foramen has the advantage of the tumor ful y exposed to the operator, which can help completely resect schwannoma and effectively avoid spinal nerve injury. Even more important thing is that the spinal stability is reconstructed by unilateral or bilateral nail-rod system, which prevents the occurrence of vertebral slippage and vertebral destabilization. Long-term effect stil needs further research.

Objective To investigate the relationship between plasma homocysteine (Hey) level and ankylosing spondylitis (AS).To analyze the association between the NS,N10 methylenetetrahydrofolate reductase (MTFHR) gene polymorphism and AS.Methods One hundred patients with AS and 60 healthy controls were included in the study.The plasma Hey level was examined by enzyme-linked immunoadsorbent assay and MTHFR gene polymorphism was analyzed by the polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP).Results Compared with heahhy controls,the plasma Hey level in AS patients was significantly higher than that of the controls (P＜0.01).There was no significant difference in the frequen-cies of MTHFR genotype and alleles between AS and the controls (P＞0.05),But the ratio of T/T genotype mutation was different between AS and the controls (P＜0.05).The plasma Hey level of T/T genotype was significantly higher than that of C/T or C/C genotype in AS and the controls (P＜0.01).Logisticalregression analysis indicated that Hey was an independent risk factor for AS (P＜0.01,0R=4.582,95%CI=1.984～10.585).Conclusion The plasma homocysteine level is significantly increased in AS patients.Hyperhomo-cysteinemia is an independent risk factor for AS.MTHFR T/T genotype mutation is an important mechanism of hyperhomocysteinemia and may be related with AS.

Objective To investigate the effects of inhalation of different concentrations of carbon monoxide (CO) on brain death (BD)-induced lung injury in rats. Methods Thirty-two pathogen free adult male Wistar rats weighing 250-300 g were randomly divided into 4 groups ( n= 8 each): group Ⅰ sham operation (group S);group Ⅱ brain death (group BD) and group Ⅲ and Ⅳ BD + CO 0.025% and 0.050% (group C1, C2 ). The animals were anesthetized and tracheally intubated. Fogarty catheter was inserted into the skull. BD was induced by inflating the balloon slowly at 20 μl/min until apnea developed. The animals were then mechanically ventilated (VT 10 ml/kg, RR 50 bpm, PEEP 2 cm H2O) with 40% O2 in N2 . In group Ⅲ and Ⅳ CO 0.025% and 0.050%were added to the air mixture respectively. In group S the balloon was not inflated. BD was confirmed by apnea,dilated pupils and flat EEG. In group BD,C1 and C2, MAP was maintained at 80-120 mm Hg by norepinephrine infusion. The arterial blood gas analysis was performed before (baseline) and immediately after BD was confirmed (T1) and at 30, 60, 90 and 120 min (T2-5) of CO inhalation. The animals were then sacrificed. The plasma concentrations of IL-6 and TNF-α and the activity of myeloperoxidase (MPO) in the lungs were measured. The W/D lung weight ratio and lung injury score (LIS) were recorded. Results BD significantly decreased PaO2/FiO2, BE and pH while increased plasma IL-6 and TNF-α concentrations, MPO activity in the lungs, the W/D ratio and lung injury score as compared with group S. CO inhalation ameliorated the deleterious effects induced by BD. The antiinfiammatory effect of 0.050% CO was better than that of 0.025 % CO. Conclusion Inhalation of 0.025 % or 0.050% CO can ameliorate BD-induced lung injury in rats, but there is no significant difference in the efficacy.

Objective To study efficacy and safety of large dose of pamidronate disodium in treatment for patients with painful bone metastasis of prostate cancer. Methods A total of 100 patients with painful bone metastasis of prostate cancer were randomized into large dose group and conventional dose group, with 50 cases each. Pamidronate disodium was administered by intravenous infusion, 90 mg on the first day and 60 mg on the second day for large dose group, and 60 mg on the first day and 30 mg on the second day for conventional dose group, respectively, every 4 weeks for two courses. Changes of pain,mobility, quality of life and adverse effect in patients before and after treatment were observed. Results After treatment, pain was relieved in 43 of 50 patients ( 86% ) in large dose group, significantly more than that in conventional dose group (21/50, 42% ) (χ2 = 22.79, P ＜ 0. 01 ). Both mobility and quality of life were improved in 39 and 33 patients ( 87% and 66% ), respectively in large dose group and 21 and 18 (46% and 36% ), respectively in conventional dose group (χ2 = 17.04 and 9. 00, P ＜0. 01 ). No severe adverse effect in both groups was observed. Conclusions Pain in patients with bone metastasis of prostate cancer can be significantly relieved with large dose of pamidronate disodium, as well as their quality of life improved.
