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 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

0. 05). This paper surggests that the activity of Na+-K+ ATPase on erythrocyte membrane may be a indicator in the diagnosis of stroke and human senility. The mechanism of changes of Na+-K+ATPase was also discussed in this paper.

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 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 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.

AIM:To investigate the time course of nuclear factor-κB (NF-κB) and the effects of 3-aminobenzamide (3-AB) on the expressions of NF-κB,interleukin-1β (IL-1β) and cyclooxygenase-2 (COX-2) in hippocampus after seizures. METHODS:Epilepsy were induced by kainic acid through cerebral ventricular injection. Western blotting was used to detect NF-κB p65 expression in nucleus at various experiment groups. Moreover,mRNA and protein expressions of IL-1β and COX-2 in different experiment groups were determined by RT-PCR and Western blotting analysis. RESULTS:NF-κB p65 immunoreactivity began to increase in the nuclear fraction at 2 h (P<0.05),kept rising at 12 h (P<0.05) and returned to control level at 24 h after epilepsy seizures. Furthermore,3-AB sharply decreased the accumulation of NF-κB p65 in nucleus (P<0.05). In addition,3-AB significantly decreased the mRNA and protein expressions of IL-1β and COX-2 which obviously increased in hippocampus at 6 h after epilepsy seizures (P<0.05). CONCLUSION:Seizures triggers NF-κB nucleus translocation and promotes the expressions of IL-1β and COX-2 in hippocampus. In addition,poly (adenosine diphosphate-ribose) polymerase inhibition by 3-AB suppresses NF-κB associated inflammatory pathway in epileptic rat hippocampus.

Objective To discuss the feasibility of using serum complement C5a and C5b-9 as predictive indicators of liver injury severity in traumatic rats with hemorrhagic shock.Method Fifry healthy male Wistar rats were randomly(random number)divided into normal group,model 1 hour group,model 3 hours group,model 6 hours group,and model 24 hours group.Plasma CH50,C5a and C5b-9 were detected by using enzyme-linked immunosorbent assay,and rate method was used for determination of plasma aspartate aminotransferase.Paraffin sections of hepatic tissues were used to observe the damage of liver.Results In the model l h group,the CH50 increased significantly and reached the highest value,it began to decline in 3 hours group,and it reached the lowest point in 24 hours group.Compared with the model 3 hours group,6 hours group,and 24 hours group,the level of CH50 in model 1 hour group increased more significantly(respectively P<0.05).A small amount of C5b-9 in the normal group was detected.In the model 1 h group,C5b-9 increased significantly and reach the peak compared with 3hours group,6hours group and 24 hours group,respectively(P<0.05),but in the model 3hours,it began to decline,and in 24 hours group,it reduced to minimum.C5a increased insignificantly in the model 3 hours group,6 hours group and 24 hours group,and peaked in 24 hours group compared with normal group(P<0.05).Aspartate aminotransferase in the model 1 hour group increased significantly and peaked in 24 hours group compared with other groups(P<0.05).Conclusions A large number of complements are activated in the seRing of hemorrhagie shock.C5b-9 and CH50 increase significantly in the early stage,and C5a.increases significantly in the later stage.C5b-9 can be considered as,an initiative factor of liver injury.The low levels of C5a in the early stage may be a mechanism of self-protection of the body.The high levels of CSa in the later stage may be a kind of decompensation,and C5a can be used as a late predictor of disease severity.

Objective To investigate infection rate of human papillomavirus as well as the correlation between cervical precancerous lesions and co-infection of human HPV,herpes simple virus-2 (HSV-2) and cytomegalovirus (CMV) in Chinese women of childbearing age in Kunming,Yunnan province.Methods A total of 2128 women (18-24,25-34,35-49 years of age),who had healthy care examination in our institute from January 2010 to March 2011,were selected prospectively in this study.The infection of HPV,HSV-2 and CMV were detected by real-time fluorescence quantitative polymerase chain reaction (FQ-PCR) and cervical precancerous lesions were determined by the ThinPrep liquid-based cytology test (TCT).Results The overall infection rates of high risk HPV (HR-HPV),HSV-2,CMV were 11.04％(235/2128),3.52％ (75/2128) and 5.26％ (112/2128),respectively.The HR-HPV infection rates in groups of Negative for Intraepithelial Lesion or Malignancy (NILM),Atypical Squamous Cells of Undetermined Significance (ASCUS),Low grade Squamous Intraepithelial Lesion (LSIL),High grade Squamous Intraepithelial Lesion(HSIL),and Squamous Cell Carcinoma (SCC) were 4.29％ (82/1912),55.93％ (66/118),84.62％ (44/52),93.19％ (41/44) and 2/2,respectively.HR-HPV infection rates was increased with the development of cervical lesion (r =0.644,P =0.000).No significant difference on the infection rates of HR-HPV and HSV-2 was identified between different age groups (x2 =2.979,P =0.226; x2 =0.798,P =0.671).The peak age groups for CMV infection (7.62％) were 18 to 24 years old and the infection rates of CMV decrease with age.No significant difference of HSV-2 and HR-HPV coinfection was found between the TCT-abnormal (3.24％,7/216) and control groups (2.41％,46/1912,x2 =0.557,P=0.455),and no relationship was found between HSV-2 and HR-HPV infection groups (OR =0.56,95％ CI:0.17-1.82).The infection of HR-HPV were related significantly with CMV infection (OR =3.14,95％ CI:1.25-7.86).Conclusion HR-HPV infection appears to be the key risk factor for cervical cancer and synergistic interaction may occur between CMV and HPV infections in the development of cervical lesion.
