Experiments on humans and rats were conducted to observe the adaptation of exercise-induced muscle injury to repeated exercise. The results indicated that the ratings of perceived exertion (RPE) in the male students of the Physical Education Department reached to the peak immediately after one bout of exercise, while the muscle soreness, the contents of serum creatine kinase (CK) and myoglobin (Mb) reached their peak on the third day post exercise, but later they gradually recovered until to their pre-exercise level on the seventh day post exercise. More obvious changes took place in the RPE, muscle soreness, serum CK and Mb one week after exercise compared with those after one bout of exercise, however, recovery began on the fourth day post exercise in the above indices. Moreover, the results in rats showed the most serious damage in the ultrastructure of skeletal muscle 24 to 48hs after one bout of exercise, but the damage became less serious on the seventh day after exercise. Besides, after 7-day repeated exercise of the same intensity, no further damage was seen in the ultrastructure of skeletal muscle, and the damage recovered on the seventh day after exercise. The results of this study suggested that an adaptation response had taken place after repeated bouts of exercise.

Objective To study the standardization of analgesia in total knee replacement (TKA),and to assess its efficacy and safety of perioperative period application.Methods 64 cases of total knee arthroplasty cases were selected,with 30 cases of male,and 34 cases of female(Aged 61 -78),included 28 cases on the left side,and 36 cases on the right side.According to the random of prefabricated CARDS (1 :1 parallel design of experiment) patients were divided into observation group and control group,with 32 cases in each group(17 cases were women, 15 cases were male,).The observation group were treated with standardized analgesia,the control group were treated with traditional postoperative controlled intravenous analgesia (PCIA)pump.48 h after surgery,the different time points after waking up general anesthesia visual analogue scale (VAS),giving pain sleepers auxiliary analgesic drug application were recorded.VAS score and analgesic drug usage and complications (nausea,vomiting,respiratory depression,motor nerve paralysis,etc.)incidence index etc.of the two groups of patients were compared.Results 64 patients were included in the study,the differences of the two groups of patients in age [observation group:(68.22 ± 0.18),the control group:(69.69 ±0.17),t =5.767,P =0.8237)],gender(15 cases were men,17 cases were women),body mass index [BMI,observation group:(23.38 ±0.19),the control group:(23.94 ±0.14),t =2.339, P =0.082)],the American society of anesthesiologists (ASA)classification (both for 10 cases of ASA grade I,ASA grade II 22 cases),had no statistical significance (P >0.05).And different time points after surgery anesthesia to VAS score had significant difference:[(control group:6 h resting 2.888 ±0.049 /ankle pumps 2.941 ±0.028,12h resting 4.731 ±0.028 /ankle pump 5.747 ±0.033,24h resting 6.859 ±0.033 /ankle pump 7.175 ±0.03,48h resting 4.14 ±0.03 /ankle pumps 5.209 ±0.025.observation group:6h resting 1.316 ±0.024/ankle pumps 1.884 ± 0.023,12h resting 2.05 ±0.02 /ankle pump 3.060 ±0.02,24h resting 2.35 ±0.02 /ankle pump 3.934 ±0.018, 48h resting 2.119 ±0.015 /ankle pumps 2.317 ±0.017.t value resting/ankle pump:6h,17.80 /28.75.12h,76.67 /69. 14.24h,116.9 /91.95.48h,61.11 /95.51.P <0.01)].Analgesic drug usage (control:55.97 ±0.25,the observation group:19.53 ±0.19,t =113.1,P <0.01),the incidence of complications (control:0.45 ±0.00,observation group:0.06 ±0.00;t =169,P <0.01 ),and other aspects of the differences were statistically significant (P <0.05 ).

Cranial irradiation is routinely used for the treatment of almost all brain tumors,but it may cause disastrous injury in brain,especially in the hippocampus that has cognitional and emotional regulation functions.Several studies have investigated the mechanisms of radiation-induced hippocampal dysfunctions such as hippocampal neurogenesis,neurotrophin and neuroinflammation,and provided effective prevention strategies such as exercise,environmental enrichment,anti-inflammatory and intrahippocampal transplantation of neural stem cells.This review discussed the curent progresses and challenges of hippocampal dysfunction induced by cranial irradiation and provided new insights for preclinical and clinical researches.

Androgen receptors appear to play a significant role in the hepatocarcinogenesis.Androgen receptors are found to be expressed in liver tumor,and the overexpression of androgen receptor is associated with poor prognosis.Recent researches have indicated that androgen receptors regulate various cellular events in liver carcinogenesis through various ways,and androgen receptor could be a potential cancer therapeutic target in hepatocellular carcinoma.

BACKGROUND: BK viral infection after renal transplantation influences the prognosis of BK virus-associated nephropathy in renal transplant recipients. The disease has been widely studied in foreign countries.OBJECTIVE: This study was designed to sum up the diagnosis and treatment of BK virus-associated nephropathy after renal transplantation.RETRIVAL STRATEGY: Using the terms "renal transplantation; BK virus" in the English language, manuscripts responsible for BK virus-associated nephropathy after renal transplantation that were published from January 2000 to January 2007 were retrieved from the PubMed database. A total of 206 manuscripts were obtained and primarily screened. Inclusion criteria: studies addressing BK virus-associated nephropathy after renal transplantation. Exclusion criteria: repetitive studies.LITERATURE EVALUATION: The included manuscripts were primarily from PubMed database. Manuscripts were primarily original and review studies.DATA SYNTHESIS: BK virus can be found in the urine of 3%-40% of adult renal transplant recipients. BK virus reactivation rate is very high, but the histological manifestations of BK virus associated nephropathy are found only in a small number of renal transplant recipients. The prognosis of BK virus associated nephropathy is very poor. BK virus associated nephropathy develops into renal failure, leading to transplant loss, in 30%-50% patients. BK virus-caused renal transplant disease must be diagnosed according to histological manifestations. Viral infection should be primarily confirmed, but serological measurements have no predominant effects. Electron microscopy should be involved in the assessment of renal graft biopsy, especially when renal failure factors are unknown, as through the use of electron microscope, viral particles in the nucleus, cytoplasm and outside of the cells could be detectable. Viral antigen in the urine sample of patients with BK viruria can be detected by nucleic acid hybridization method, immunofluorescence, and ELISA. Cidofovir is an effective medicine for treatment of BK virus-associated nephropathy, but its potential nephrotoxicity, proper dose, pharmacokinetics, safety, tolerance, anti-BK viral activities have not been confirmed. So fresher study should be required for aforementioned uncertainties.CONCLUSION: BK virus-associated nephropathy has poor prognosis and should be diagnosed according to histological examinations. BK virus-associated nephropathy has been treated primarily by symptomatic supportive treatment and reducing the dose of immunosuppressive agents.

It was well known that the damage of skeletal muscle occurred and exercise performance declined after one prolonged eccentric exercise.But there were few studies on the adaptation to the continuous eccentric exercise in skeletal muscle.The purpose of this study was to investigate the effects of downhill running once(group B) and for one week(group C ) on α-actin gene expression of rat gastrocnemius muscle.Serum CK and LDH were determined, too.The results showed that the training had obvious effects on α-actin gene expression of rat gastrocnemius muscle in group B and C.In group B, serum CK and LDH recovered obviously 7 days after training, but not to the normal value.In group C, it recovered to the normal.These results suggest that the recovery of the damage after first training had been accelerated by the continuous eccentric exercise, the subjects gradually adapted to exercise.

Objective To investigate the change of S-100B in serum in rats at varions times after exposure to different whole-brain irradiation doses and to explore the characteristics of the S-100B change in early radiation-induced brain injuries. Methods A model of brain radlation-induced injuries was estabhshed in the rat after whole-brain irradiation with a single dose of 2, 10, or 30 Gy of 4 MeV electron. The concentration of S-100B in serum was detected by means of enzyme-linked immunoserbent assay (ELISA) at different time points (1,6,12,24,3 days, 1 week, 1 month) after exposure. Results In terms of measuring time points, the serum concentration in all groups reached the fwst peak 6 hours after irradiation, declined after 12 hours, rose again after 24 hours, and started to decline again until the last time point (1 month), with the exception of the 2 Gy group, which reached the second peak at 3 days after irradiation. Conclusions The S-100B serum concentration was changed in the rats after whale-brain irradiation and these changes are positively related to the irradiation amount. It seems that the higher the dose, the higher the serum concentration and the differences between the dose groups are significant (via multiple regression models). The S-100B may be a valuable serum marker for the brain irradiation injury.

Abnormal reaction in preventive vaccination is the serious adverse reaction happened in regular vaccination. Department of government and producer of vaccines are liable legislatively. In my opinion, relief fund for abnormal reaction should be established to cover the damage of victims and to decrease the risk of government and enterprises.
