Chinese Journal of Rehabilitation Theory and Practice 1996;2(4):154-158
In this paper a series of gait quantitative assessment indexes:phase symmetry index,verti-cal force symmetry index,equilibrium function index,and brake and drive function indexes are obtainedwith VICON 3-dimensinal movement analysis system according to the results that 40 amputees,50 cerebralpalsy patients, 31 hemiplegia patients and 19 paraplegia are evaluated and the differences between the nor-mal and the abnormal(p<0.001)found with these indexes. The quantitative assessment methed of walk-ing function not only provides rehabilitation level of patients and for checking therapeutical effects,but alsolaies the foundation of gait analysis to standardization and practicalization further.

Objective To investigate the effect of salidroside on brain edema and neurological function in global cerebral ischemia-reperfusion injury in rats.Methods A total of 100 Sprague Dawley rats were randomly divided into sham operation,ischemia-reperfusion and salidroside 12,24 and 48 mg/kg groups (n =20 in each group),and than redivided into 6 h,24 h,72 h and 7 dsubgroups (n =5 in each subgroup).A rat model of global cerebral ischemia was established using the four-vessel occlusion method.Immediately after modeling,all groups were administered intragastrically for 7 days.The brain water content was quantitated by the wet-dry weight method.The neurological evaluation was performed using a neurological deficit score (NDS).Results After modeling both the ischemia-reperfusion group and all the salidroside groups had significant neurological deficit,and as time went by,it was improved gradually.Compared to the ischemia-reperfusion group at the corresponding time points,neurological deficit in all the salidroside groups was improved significantly (all P < 0.05),and showing a dose-dependent trend.Compared to the salidroside 12 mg/kg and 24 mg/kg groups,neurological deficit in the salidroside 48 mg/kg group was improved significantly at 72 hours and 7 days (all P < 0.05).The brain water contents began to increase at 6 hours after modeling in the the ischemia-reperfusion group and all the salidroside group.They reached the peak at 72 hours,and significantly higher than that in the sham operation group (all P < 0.05).The brain water contents in all the salidroside group were significantly lower than those in the ischemiareperfusion group at 24 and 72 hours after modeling (all P < 0.05) and showing a dosedependent trend.The brain water content in the salidroside 48 mg/kg group was close to that in the sham operation group at 7 days after modeling.Conclusions Salidroside may significantlydecrease brain edema and improve neurological function in global cerebral ischemia-reperfusion injury in rats,and it has a neuroprotective effect.

Objective To investigate the effects of 17-β estradiol on hepatocyte apoptosis and the expression of Bcl-2 and Bax in hepatic tissue after reduced-size ischemia reperfusion injury and its mechanism in liver protection.Methods A rat model of reduced-size hepatic ischemia-reperfusion injury was established in 75 male Sprague-Dawley rats.They were randomly allocated into three groups:Sham group,ischemia-reperfusion(IR)group,and 17-β estradiol(E2 + IR)group.Liver functions,liver histology and hepatocellular apoptosis rates were observed after reperfusion.Hepatocellular ap optosis was determined by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL)method and the expression of Bcl-2 and Bax were determined by Western blotting.Results The levels of ALT and AST were higher and peaked after 12 h of reperfusion in the IR group compared with the sham group.The histological changes in the liver of the IR group consisted of hepatocyte swelling,hepatic sinusoids narrowing,inflammatory cell infiltration and hepatocyte necrosis in some areas of the livers.The IR group also exhibited an increased rate of hepatocellular apoptosis at 12 h after reperfusion.The protein expression of Bcl-2 decreased while the expression of Bax increased.In the 17-β estradiol group,the levels of ALT and AST were lower,the pathological changes were milder and the rate of hepatocellular apoptosis was lower at 12 h in comparison to those of the IR group.The expression of Bcl-2 was higher and the expression of Bax was lower in the 17-β estradiol group in comparison to those of the IR group.Conclusions 17-β estradiol can relieve the hepatic ischemia reperfusion injury in rat livers.17-β estradiol may inhibit apoptosis in hepatic tissue by up regulating Bcl-2 and down-regulating Bax,thus producing a protective effect on hepatic ischemia-reperfusion injury.

Purpose To investigate the correlation between BRAF V600E mutation and clinicopathologic parameters in bilateral welldifferentiated thyroid carcinoma.Method Collected 80 patients with papillary thyoid carcinoma (PTC) (67 patients with classical type,8 patients with follicular variant,3 patients with oncocytic variant,2 patients with tall cell variant),5 patients with follicular carcinoma and 30 normal tissues near the tumor,BRAF V600E mutation was detected via polymerase chain reaction.Result The presence of BRAF V600E mutation was found in 52 patients with PTC (65.0%),the mutation was not in the 5 patients with ollicular carcinoma as well as in the 30 normal tissues near the tumor.The BRAF V600E mutation was positively correlated with age,capsule invasion,lymph node metastasis,tumor clinical stage.In the histological variant of PTC,the BRAF V600E mutation rate of classical type and tall cell variant is very high (70.1%,100.0%),but the BRAF V600E mutation rate of follicular variant is very low (33.3%).Conclusion The BRAF V600E mutation rates are different in different age groups.The BRAF V600E mutation was positively correlated with capsule invasion,lymph node metastasis,tumor clinical stage.The BRAF V600E mutation rate of classical type and tall cell variant is very higher than follicular variant.

Objective This study aims to understand the characteristics of the time sequence of ICR mouse first mandibular molar tooth germ development through dynamic observation.Methods Tooth germ of Embryos (E11.5,E12.5,E13.5,E14.5,E15.5,E16.5,E17.5 and E18.5) and postnatal (PN1,PN2) mice were obtained.The heads (E11.5-E15.5) and mandibles (E16.5-PN2) of mice were dissected,fixed and embedded for serial sections and HE staining.All the results were assessed under light microscopy.Results The tooth germ underwent various development stages including the bud,cap and bell stages.Mouse odontogenesis was initiated at E11.5.Proliferation of oral epithelium formed the bud stage at E13.5.Then the cap stage was observed at E14.5-E15.5 and the bell stage was appeared beginning from E16.5.The pre-dentin was observed at PN1,as well as the dentin at PN2.Conclusions Establishing the regular development pattern of the first mandibular molar of ICR mice will provide a reliable basis for the future use in the specific tooth germ developmental research.

Objective To study the impact of postoperative aerobic exercise on the cardiac function of breast cancer patients during anthracyclines-based chemotherapy. Methods Sixty cases of female breast cancer pa-tients, from June 2014 to December 2015 for anthracyclines-based chemotherapy, were randomly divided into ex-perimental group (n = 30) and control group (n = 30). Four cycles of conventional anthracyclines-based chemotherapy were conducted in control group, while three times of aerobic exercise per week were added in exper-imental group until the end of treatment course apart from conventional treatment. The peak oxygen consumption (VO2max) and maximum heart rate (HRmax) were measured before and after chemotherapy in both groups, ac-companied by ECG monitoring and blood collecting to measure the changes in their N-terminal pro-brain natriuretic peptide (NT-proBNP), serum creatinine (SCr) and kinase isoenzyme (CK-MB). Results No significant differ-ences in various indicators before chemotherapy were reported between two groups (P>0.05). After chemotherapy, VO2 max/kg [(21.9 ± 3.6) vs. (14.5 ± 2.8) mL/(min·kg)], VO2 max [(1 523 ± 186) vs. (911 ± 185) mL/min] and HRmax[(115 ± 15) vs. (129 ± 16) beats/min] in experimental group were significantly improved when com-pared with those in control group; significant differences in hematological levels and ECG changes were also ob-served between two groups. Conclusion Aerobic exercise during chemotherapy can mitigate the cardiotoxicity of anthracyclines to patients, which provides a new idea and therapy to reduce the incidence of clinical cardiovascular events induced by anthracyclines-based chemotherapy.
