Hip-stressed lower limb specific strength training apparatus is a new kind of training equipment with the combination of specific technical strength training and quantitative evaluating. Base on the mechanism of sports physiology and sports biomechanics, by applying the theory of motor learning and control, the apparatus adopts the training model of the "hip stress loading device" and "hip-feet starting and ending stress point" to simulate the track of working limb in running, jumping and throwing, controls the degrees of body movement freedom reasonably. For the first time, actualizes the heavy load specific strength and sports skill training of leg driving, leg pawing and trunk-backward knees-bend leg driving. The distinctive training pattern of forced track control and the training method of strength & skill coupling" used in this apparatus, makes the action in strength training approach to real sport skill in greatest extent, and shifts the result of strength training to the skill training as much as possible. So it remarkably increase the efficiency of strength training and has an great importance in changing the concept of strength training.

Aim To explore the effect of propofol preconditioning on myocardial ischemia/reperfusion injury and the role of phspho-ERK1/2 during the propofol preconditioning in renal hypertension rat(RHR).Methods The isolated RHR hearts perfused on langendorff apparatus were randomly divided into 8 groups(n=8 each).After 20 min of perfusion for equilibration,the CTRL group was subsequently perfused by 148 min.The ISCH group was submitted to 35 min of ischemia and 60 min of reperfusion(I/R) to induce ischemia/reperfusion injury.The DMSO group was given by once 18 min and twice 10 min K-H solution containing 20 ?mol?L~(-1) DMSO and 5 min K-H solution reperfusion prior to I/R procedure.The three propofol preconditioning groups were preconditioned by giving 2 cycles of 10 min K-H solution containing 30 ?mol?L~(-1),100 ?mol?L~(-1) or 300 ?mol?L~(-1) propofol and 5 min K-H solution reperfusion prior to the I/R procedure.The PD group and the PD+P100 group were given K-H solution containing 20 ?mol?L~(-1) PD98059,an ERK1/2 kinase specific inhibitor,for 18 min and 5 min K-H solution washout before I/R and 100 ?mol?L~(-1) PPC respectively.Cardiac functional indices were recorded.Activity of SOD and content of MDA were measured.The level of phspho-ERK1/2 protein expression was measured using Western Blotting.Results Compared with those in the CTRL group,the recovery of cardiac functional indices in ISCH group became worse(P

OBJECTIVE To identify the risk factors for infections in patients with cirrhosis.METHODS A case-(control) study was employed.A total of 286 patients hospitalized between 1999 and 2003 were included in.Patients who developed infection complication were defined as case,the remains were as control.The data of possible risk factors,including serum levels of albumin(Alb),prothrombin time(PT),total bilirubin(T-Bil),Child-Pugh score,ascite,esophageal variceal bleeding,total cholesterol(T-chol),other complication,the total white blood cell(wbc),surgery,and days of hospitalization,were retrospectively collected.According to multivariate Logistic regression model,the potential risk factors were assessed.RESULTS Infections developed in 127((44.4%))(patients) and 100(78%) of those developed infection during hospitalization.The mortality rate of case was(20.5%,) which was significant higher than that of control(3.1%,P0.08).Fifty five patients(30.7%) had spontaneous bacterial peritonitis(sbp).Bacterial culture of samples were prepared from 97 of 127 patients((76.4%),) and was positive in 62(63.9%) patients.From these culture-positive samples,35(56.4%)(samples) were Gram-negative bacterial strains,8 of 15 samples from patients developed sepsis were Gram-positive bacteria.On multivariate analysis,the Alb level and days of(hospitalization) were the independent risk factors for cirrhosis patients with infection complication.The odds ratio was 0.33(95% CI(0.32)-0.55),and 0.23(95% CI(0.14)-(0.38),) respectively.CONCLUSIONS Patients with advanced cirrhosis with low Alb level and long days of(hospitalization) should be carefully treated,and administration of broad spectrum antibiotic covering Gram-positive bacteria needs to be considered in treatment of sepsis.

Objective To research the efficacy and healing rate of radical cure surgery by one time in perianal abscess in infants.Methods 46 cases infant perianal abscess were cured by radical cure surgery for once and the healing rate was observed.Results All of 46 cases were healed.Conclusion The radical cure by one time was an effective procedure for perianal abscess in infants.

Thymomas are most frequent primary tumors of anterior mediastinum.Surgery is the principal treatment method.Thymomas are sensitive to chemotherapy,and chemotherapy has showed a sig- nificant anti-tumor effect in locally advanced,recurrent or metastatic thymomas.Chemotherapy,radiother- apy or combined chemotherapy and radiotherapy before or after operation can offer patients excellent re- sponses,improve resectable rate.Some patients who are once inoperable obtain curative and palliative operation.Radiotherapy after operation can decrease residual tumor tissue,increase local control,de- crease recurrence,and prolong the survival.The multimodality therapy plays an important role in thy- moma treatment.

(Ver)-induced human retinal pigment epithelium (RPE) cells apoptosis.hours to induce RPE cells apoptosis.The expression of apoptotic effector gene caspase-3 was assessed by reverse transcription polymerase chain reaction (RT-PCR).Single cell was measured using fluorescence indicator Fura-3/AM with MetaFluo4.5/coolsnapfx/IX70 intracellular Ca2+ fluorescence imaging system.RPE cells and it significantly increased after co-cultured with Ver.The fluorescence in resting RPE cells was strong and distributed throughout the cells.The nucleus appeared more fluorescent than the cytoplasm.Calcium fluorescence of RPE cells attenuated after co-cultured with Ver.[Ca2+]i homeostasis might play pivotal roles in Ver-induced RPE cells apoptosis.

OBJECTIVE: To synthesize asialoglycoprotein receptor ligand-targeted modifier which is used to insert the surface of liposome by enzyme-catalyzed amidation of lactobionic acid and stearamine. METHODS: The structure of the product was confirmed by IR, ESI-MS and H1-NMR. The effects of types and quantity of enzyme, organic solvents, molar ratio of substrate and temperature of reaction were studied. RESULTS: When using DMSO as reaction medium, Novozym 435 immobilized lipase at 400 U · mL-1, molar ratio of lactobionic acid to stearamine at 2:1, and reacting at 40°C for 24 h, the transformation of stearamine reached more than 99%. CONCLUSION: The enzyme catalysis is useful for synthesizing liver targeting liposomes.

ObjectiveTo study the method about language rehabilitation for Broca aphasis with bucco-facial apraxia in hemiplebies after stroke.Methods55 patients in hemiplegies after stroke who were diagnoised Broca aphasia with bucco-facial-apraxia by Chinese standard language test of aphasia and apraxia test,were randomly divided into two groups:treatment group(30 cases) and control group(25 cases). The trainning about language rehabilitation and occupational therapy(OT)to bucco-facial-apraxia were given in the treatment group, while in the control group the language rehabilitation training were given only. Evaluation was done in pre-treatment and post-treatment respectively.ResultsThe improvement of bucco-facial-apraxia and language expression function(repetition,speech and speech-reading) of treatment group were significant than that of control group (P<0.05).Conclusions The OT for bucco-facial-apraxia may obviously improved bucco-facial-apraxia and language expression function on training of language rehabilitation for Broca aphasia with bucco-facial-apraxia.
