ObjectiveTo observe effects of modulated medium frequency low frequency current hydroelectric bath therapy on sequela of ankle fracture.Methods32 sequela patients of ankle fracture were treated with ZM-C type intellectual faculties intermediate frequency therapeutics instrument. Modulated medium frequency square all wave,the frequency of carry wave was 4 KHz,and the frequency of modulated wave was 100 Hz. The water temperature was 40℃. 30 minutes was a time,12 times was a course. Before and after treatment,results were contrasted themselves.ResultsAfter treatment,32 patients all got satisfactory effects,the shorter of the course,the better of the effect.ConclusionThe modulated medium frequency low frequency current hydroelectric bath therapy is a simple,safe and better effect method for sequela of ankle fracture.

Objective To investigate the effect of pronuciferine on apoptosis of cultured human umbilical vein endothelium cells(HUVECs) induced by angiotensin Ⅱ(AngⅡ).Methods HUVECs cell line ECV304 was cultured in vitro,pretreated with Captopril(10 ?mol/L) or pronuciferine 10,1,0.1,0.01 ?mol/L for 30 min,respectively,then treated with AngⅡ(1 ?mol/L).Cell-morphosis was observed by light microscope.Cells viability was assessed by MTT assay.Production of nitric oxide(NO),activities of total nitric oxide synthase(tNOS),and inducible nitric oxide synthase(iNOS) were measured by colorimetry.Apoptosis rate was measured by Flow Cytometer(FCM).Results AngⅡ induced typical endothelial cell apoptosis and the apoptosis rates were significantly higher than those of the control group((P

ObjectiveTo investigate the rule of changes of the soleus mass and expression of myosin heavy chain (MHC) isoforms mRNA.Methods40 female Wistar rats were divided randomly into the control group and three spinal cord transection (ST) groups, ST7, ST15, and ST30 with 10 animals in each group. Rats in ST groups were subjected to a complete ST between T8 and T10 levels. The right soleus was dissected and weighed at 7, 15, 30 days after ST, and the expression of MHC mRNA isoforms was measured by semi-quantitative reverse transcriptase polymerase chain reaction (RT-PCR).ResultsThe Absolute and relative soleus masses in three ST groups were lower significantly than those of control group (P<0.05). The soleus mass in ST15 and ST30 groups were lower than that of ST7 group (P<0.05). The soleus of control group predominantly expressed MHC-I and some MHC-IIa, whereas the soleus began to express MHC-IIx and MHC-IIb after ST, except for MHC-I and MHC-IIa. ST induced consistently down-regulation of MHC-I mRNA and up-regulation of MHC-IIx and MHC-IIa at three time points after ST. The level of MHC-IIb mRNA expression was very low at three time points after ST.ConclusionST can influence the soleus mass at early stage after ST. ST induces a shift toward a faster muscle phenotype from slow to fast MHC isoform. MHC demonstrates plasticity in response to decrease neuromuscular activation.

Objective:To explore the factors related to juvenile depression with self-mutilate behavior and suicide idea.Methods:75 cases of juvenile with depressive disorder were presented by the investigatin scale (self-made),SCL-90,coping style questionnaire,ASLEC,EMBU,CASQ.Results:Juvenile depression with self-mutilate behavior and suicide idea had gender difference,more juveniles had suicide idea with well-educated mother,juveniles with self-mutilate behavior had more self-rating psychiatric symptoms.self-mutilate behavior and suicide idea were related with negative incidents,parental rearing patterns,coping style and attributional style. Conclusion:Juvenile depression with self-mutilate behavior were influenced by more factors.

Objective To study the expression of intermediate-conductance-Ca~(2+)-activated K~+ (IKCa1)channels in endometrial cancer and its role in regulating proliferation of endometrial cancer cells. Methods Western blot and RT-PCR were used to examine the expression of IKCa1 channels in 13 normal endometrial specimens and 25 endometrial cancer specimens;and RNA interference(RNAi),[ ~3H ] thymidine incorporation,and inhibitor of IKCa1 channel were used to explore the role of IKCa1 channels in regulation of proliferation of endometrial cancer cells HEC-1A.Results The expression rate and level of IKCa1 mRNA in endometrial carcinoma(84%,0.89?0.52)were higher than in normal endometria(8%, 0.14?0.12;P

Objective: To observe the migration of 4,4＇-diaminostilbene-2,2＇-disulfonc acid-based fluorescent whitening agents ( DSD-FWAs ) in food packaging paper, so as to provide evidence for quality and safety supervision for paper packaging materials. Methods: Forty-one paper samples with DSD-FWAs positive were made into 6 cm2 pieces and were soaked in four food simulants ( distilled water, 3% acetic acid, 10% ethanol and 95% ethanol, 10 mL each ). The experiment was carried out at the specified soaking temperature and time. The migration amounts of eleven DSD-FWAs were detected by high performance liquid chromatography-fluorescence detection. Results: C.I.220, C.I.24, C.I.210, C.I.85, C.I.113, C.I.264, C.I.353 and C.I.357 were found in all the four food simulants. At the same time and temperature, the migration amount was highest in 10% ethanol, followed by distilled water, 3% acetic acid and 95% ethanol. C.I.220 was dissolved in all four food simulants, in the range of 20-90 ℃, the migration amount increased with soaking temperature; at 20 ℃, 40 ℃ and 60 ℃, the migration amount increased first and then stabilized over time. Conclusion The higher the storage temperature and the longer the storage time of paper packaging, the easier the DSD-FWAs in packaging paper migrate to food.

ObjectiveTo investigate the characteristic of hindlimb movement recovery in adult rats after spinal cord injury and how to assess it.Methods 26 adult female rats were randomized in sham,completely midthoracic spinal cord transected(at T8 level) or body weight supported treadmill training(BWSTT) groups.Their motor function were assessed with Basso,Beattie,Bresnahan locomotor rating scale for open field(BBB scale) and average combined scores(ACOS).ResultsNone of the rats exhibited hindlimb movements after operation.30 d and 45 d after operation,BBB and ACOS score of rats in BWSTT group showed better than that in SCI group.There were significant differences in ACOS score among 15 d,30 d and 45 d after operation in both group.ConclusionPartial spontaneous hindlimb functional recovery can be found in chronic adult spinal cord injured rats and BWSTT would facilitate the recovery.Both semiquantitative and qualitative assessment were strongly correlated with locomotor recovery,but the semiquantitative assessment shows more sensitive.
