The study assessed the early functional outcomes with cemented titanium implants of radius in the treatment of comminuted fractures of radial heads. The functional outcomes of arthroplasty with cemented titanium implants of radius in the treatment of radial head fractures (Mason Type III: 6; Mason Type IV: 4) in 10 consecutive patients (mean age, 38 years) were evaluated over a mean time of 23.7 months (18-31 months). The patients were assessed on the basis of physical examination, functional rating (Mayo) and radiographic findings. The parameters evaluated included motion, stability, pain, and grip strength. Five patients were considered to have excellent results, 4 patients had good results and 1 patient had fairly good results. There were no cases of infection, prosthetic failure, heterotopic ossification or dislocation. When medial collateral ligament was injured, radial head became the main stabilizing structure of the elbow. Titanium radial head implant may provide the stability similar to that of native radial head. We believe that titanium radial head implants may be indicated for the Mason Type III and Mason Type IV radial head fractures.

Objective To explore the influence of self-efficacy training on the memory and executive function of patients with ischemic stroke in the recovery stage.Methods A total of 80 cases were randomly divided into a self-efficacy training group and a control group,with 40 cases in each.The control group was given routine cognitive therapy,while the self-efficacy group was given cognitive interventions plus efficacy training.Before training and after training for 3 months,self-efficacy levels were examined using the general self-efficacy scale (GSES),memory and executive function were measured using the Behavioral Assessment of Dysexecutive Syndrome (BADS) and the Wechsler Memory Scale (WMS).Anxiety and depression were evaluated using the Self-rating Depression Scale (SDS) and Self-Rating Anxiety Scale (SAS).Results Inter-group comparison showed no significant differences in terms of GSES or BADS scores before treatment between the control and self-efficacy groups.After training,the total GSES and BADS scores in both groups were significantly higher than before.Both the average GSES and BADS scores in the self-efficacy group were significantly higher than in the control group.There were similarly no significant differences in WMS scores before treatment,but after training the WMS results were significantly better in the self-efficacy training group than in the control group.After training,the SDS and SAS scores had improved to a significantly greater extent in the self-efficacy group than in the control group.Conclusion Self-efficacy training can facilitate the recovery of memory and promote executive function in patients with ischemic stroke.

Objective To observe the toxic effects of2-methyl-4-chlorophenoxyacetic acid(MCPA)in male mice.Meth-ods The Kunming male mice were divided into4groups,10male mice per group.The control group were purfused into stom-ach by distilled water,the other three groups were perfused into stomach by20,100and200mg /kg MCPA,once a day,6times per week,continuously for17days.The body weight ,T 4 ,TSH,cholesterol,the ratio of spleen and testis to body weight and the specific activity of LDH,SDH in the testis were analyzed.Results The body weight of mice in MCPA-exposure groups in-creased more slowly than that in the control group.The contents of TSH in serum and ratio of spleen to body weight in200mg/kg group were significantly lower than those in control group.The contents of cholesterol in serum increased with the increases of MCPA-exposure doses.The contents of T 4 in serum were significantly higher in20mg /kg group and lower in200mg /kg group compared with that in control group.The ratio of the testis to body weight reduced with increase of the MCPA-exposure doses,and the specific activity of LDH in the testis of MCPA-exposure groups increased significantly,but the specific activity of SDH in the testis of MCPA-exposure groups revealed no significant variations compared with that of control group.Conclusion MC-PA inhibited the growth of male mice,resulted in endocrine disorder,the atrophy of spleen,and presented the toxicity of repro-ductive system.

Objective To study the protective effect of ginger extract on RBC of X-ray irradiated mice. Methods Mice were given extract of ginger with three doses, namely 9.3 ml/kg bw, 4.7 ml/kg bw and 2.3 ml/kg bw before X-ray irradiation(dose was 2.0 Gy, for two times, the interval was 24 h), 48 hours after the last irradiation, the blood samples were collected and RBC, HCB, HCT, MCV, MCHC, MCH, RDW were examined. Results Compared with the exposed control, RBC, HCB, HCT increased and MCH, RDW decreased significantly in ginger treated groups. Conclusion The ginger extract has a certain effect to prevent RBC from damaging induced by X-ray irradiation in mice.

Objective To study the effect of nitrobenzene(NB) on the activity of enzymes and the content of zinc in the testis tissue of mice. Methods 40 male mice were divided into 4 groups, 10 in each, 3 groups were treated with NB at the doses of 2, 20, 200 mg/kg by gavage, the control group was treated with vegetable oil in the same volume, once a day, for 21 consecutive days. The activity of G-6-PD, LDH and the content of Zn2+ in testis cells were determined. Results The index of epididymis and testis in the groups of 200 mg/kg were significantly lower compared with the control and 2 mg/kg group (P0.05). The activity of G-6-PD, LDH and the content of Zn2+ in all the treated groups were lower than those in the control group (P

To determine the effect of straight-leg-raising (SLR) movement on epidural fibrosis after laminectomy, 40 adult New Zealand rabbits were selected as laminectomy models in the study. They were divided into 2 groups: a SLR group (group S) and a control group (group C) randomly, with each group having 20 animals. All rabbits were subjected to total laminectomy in the site of S1. Every 5 rabbits in each group selected randomly were killed at the 1st, 2nd, 4th, and 8th week after the surgery. Segments of spines from L7 to S2 were removed en bloc. After gross evaluation, specimens were sliced up. The slices were stained by HE and Masson's trichrome methods respectively for histological examination. Our results showed that formation process of scar in group S was retarded as compared with that of group C at the time of the 2nd-week, but there was no statistical difference between groups in the adhesion degree (P> or =0.05). At the 4th and 8th week, the epidural fibrosis of group S was more serious than that of group C. Since the 2nd-week, the area of scar in group S was larger than that of group C. The number of fibroblasts and inflammatory cells in group S were larger than those of group C at early stage. But in later stage, there was no statistical significance between the two groups. It is concluded that SLR movement after laminectomy may promote the formation of epidural fibrosis and retard the maturity of scar. SLR movement can also aggravate scar adhesion.

0.05).After treatment,blood serum E2 level in group M was (74.18?22.32) pmol?L-1,whereas that in group D was (24.96?3.94)pmol?L-1,there was significant difference(P0.05).Conclusion Clinical symptoms of patients with recurrent endometriosis in two groups are improved.Serum E2 level in group M remains in the follicular phase,but group D declines to postmenopausal range.Mifepristone does not result in lack of estrogen,ovulation recovers rapidly after treatment in group M compared with group D.Mifepristone and danazol have not obvious impact on blood serum cortisol.

OBJECTIVE To investigate the rate of the clinical isolation of ESBLs positive Escherichia coli and the resistance in intensive care units(ICU).METHODS We isolated E.coli from 2003 to 2004 in our hospital ICU,phenotypic confirmatory test was applied to detect ESBLs.Bacterial drug susceptibility test was performed by standard Kirby-Bauer method.RESULTS The isolation rate of ESBLs positive E.coli was 74.36% in 2003 and 81.58% in 2004.ESBLs positive bacteria had high resistance to antibacterial drugs,but the resistance rate did not rise.ESBLs negative bacteria were more susceptible to antibacterial drugs(P=0.001);but ESBLs negative bacteria in 2004 had higher resistance than in 2003(?2=84.511,P=0.001).CONCLUSIONS It is very important for ICU to use ESBLs detection test in time,and antibacterial drugs in reason.
