Objective To explore the effect of fluoride and arsenic pollution on bone metabolism in exposed population. Methods One hundred and fifty-two fluoride and arsenic exposed people were selected from Jiaole village, Yuzhang town, Xingron county, Guizhou province in 2006, and 59 not exposed people from Daguoduo village 13 km away from Jiaole village were selected as control. Urinary fluorine(UF), urinary arsenic (UAs), urinary hydroxyproline (UHYP), cross-linked N-telopeptides of type I collagen (UNTX) and bone strength index(STI) were detected. Results The main effect of fluoride on UHYP and UNTX were statistically significant (F = 9.785, 4.225, P < 0.01 ), but was not significant on STI(F = 0.183, P > 0.05). The main effect of arsenic on UNTX was statistically significant (F = 2.660, P < 0.05 ), but was not significant on UHYP and STI(F = 2.012, 0.183,all P > 0.05). The interaction between fluoride and arsenic on UNTX was statistically significant (F= 2.429, P <0.01), but was not significant on UHYP and STI(F= 1.218, 1.001, all P> 0.05). Conclusions Fluoride exposure can affect the metabolism of collagen and bone resorption, and Arsenic exposure main affect bone resorption, fluoride and arsenic co-exposure have more significant effect on bone resorption. UNTX may be used as biological biomarker of bone metabolism for population co-exposed to fluoride and arsenic in health monitoring.

ObjectiveTo observe the effect of language rehabilitation training on stroke patients with complete aphasia.Methods10 stroke patients with complete aphasia were treated with language rehabilitation training.ResultsAfter training, scores of hearing, naming, reciting, reading, and writing of patients were significant higher than that before training (P<0.05—0.01).Conclusion Language rehabilitation training plays an active role in rehabilitation of stroke patients with complete aphasia.

This study aimed to investigate the reconstruction of the thumb and finger extension function in patients with middle and lower trunk root avulsion injuries of the brachial plexus.From April 2010 to January 2015,we enrolled in this study 4 patients diagnosed with middle and lower trunk root avulsion injuries of the brachial plexus via imaging tests,electrophysiological examinations,and clinical confirmation.Muscular branches of the radial nerve,which innervate the supinator in the forearm,were transposed to the posterior interosseous nerve to reconstruct the thumb and finger extension function.Electrophysiological findings and muscle strength of the extensor pollicis longus and extensor digitorum communis,as well as the distance between the thumb tip and index finger tip,were monitored.All patients were followed up for 24 to 30 months,with an average of 27.5 months.Motor unit potentials (MUP) of the extensor digitorum communis appeared at an average of 3.8 months,while MUP of the extensor pollicis longus appeared at an average of 7 months.Compound muscle action potential (CMAP) appeared at an average of 9 months in the extensor digitorum communis,and 12 months in the extensor pollicis longus.Furthermore,the muscle strength of the extensor pollicis longus and extensor digitorum communis both reached grade Ⅲ at 21 months.Lastly,the average distance between the thumb tip and index finger tip was 8.8 cm at 21 months.In conclusion,for patients with middle and lower trunk injuries of the brachial plexus,transposition of the muscular branches of the radial nerve innervating the supinator to the posterior interosseous nerve for the reconstruction of thumb and finger extension function is practicable and feasible.

The growing status of Anoectochilus roxburghii seedling was observed and the survival rate of seedlings, height, stem diameter and plant fresh weight under the conditions of different transplanting substrate compositions, planting density, shading rate were measured. The results showed that the effects of different transplanting substrates, planting densities, shading rates and nutrient solutions on the growing status of A. roxburghii plantlets varied greatly. A. roxburghii plantlets demonstrated a high survival rate and better growing status under the Following conditions: the ratio of peat and river sand as 2: 1, the planting density as 3 cm x 3 cm, the shading rate as 70%, and the nutrient solution as 1/4MS. The findings of the study provide a solid technical solution for the artificial cultivation of A. roxburghii plantlets.

Objective:To express Tumstatin_(183-230)-TRAIL fusion protein and to observe its biological functions.Methods: SOE-ing PCR was employed to amplify the recombinant sequence of Tumstatin_(183-230)and TNF-related apoptosis-inducing ligand (TRAIL_(114-281)).An expression vector pMAL-Tu-T was constructed by inserting Tu-T sequence into pMAL-c_2;the vector was used to transfect E.coli BL21(DE3)and expression of MBP-Tu-T fusion protein was induced by IPTG.Amylose Resin columns were employed to purify the fusion protein.The biological functions of MBP-Tu-T protein was examined by inhibitory test of endothelial cell proliferation,standard tumor cell cytotoxic assay,in vitro tube formation inhibition,and electron microscopic observation(apoptosis).Results:The expression rate of MBP-Tu-T fusion protein in E.coli was about 20%. Purified recombinant protein obviously inhibited endothelial cell proliferation(IC_(50)12.5?g/ml),induced apoptosis of pancreatic cancer cells,and inhibited tube formation.Conclusion:Constructed MBP-Tu-T fusion protein is bifunctional,which lays a solid foundation for further investigation of antitumor effect of Tumstatin_(183-230)-TRAIL in vivo.

Objective To explore the current status of the family function and the influential factors in the community, Methods A questionnaire survey including the general data questionnaire and APGAR scale developed by Smikstein was conducted in 94 families of three communities of Wuhan City. Results 46.8% of the surveyed family showed good function, 51. 1% showed moderate dysfunction and 2.1% in severe dysfunction. The multinomial regression revealed that education level and whether the family members had chronic diseases had influence to the family function level (P<0.05). Conclusions More than 50% of the families exist moderate or severe family dysfunction. The higher education level, the better family function; meanwhile compared with the family whose members experience chronic diseases, the family without experiencing chronic dieseases shows much better family function.

Objective To investigate the clinical efficacy of contralateral acupuncture in treating motor dysfunction in patients with acute ischemic stroke.Methods Sixty patients with acute ischemic stroke were randomized to treatment and control groups, 30 cases each. Both group received electroacupuncture in addition to conventional rehabilitation training. Besides, the treatment group received electroacupuncture at points on the healthy side in the morning and on the affected side in the afternoon and the control group, electroacupuncture at points on the affected side in both the morning and afternoon. Motor function was assessed using the Fugl-Meyer Assessment (FMA), the modified Barthel Index (MBI), integrated electromyography (iEMG) and median frequency (MF) in the two groups of patients before and after treatment.Results There were statistically significant pre-/post-treatment differences in the FMA score, the MBI score, iEMG and MF in the two groups (P<0.01). There were statistically significant post-treatment differences in the FMA score, the MBI score and iEMG between the treatment and control groups (P<0.01,P<0.05).ConclusionContralateral and healthy side acupuncture can markedly improve motor function in acute stroke patients.

OBJECTIVETo evaluate the effect of Xuesaitong injection (XSTI, a preparation of Panax Notoginseng) as auxilliary treatment of severe craniocerebral injury.

METHODSEighty-seven patients with severe craniocerebral injury were selected and randomly divided into the treated group (n = 44) and the control group (n = 43), they were treated with conventional treatment, and XSTI was given additionally to the treated group. Intracranial pressure (ICP) and Glasgow coma score (GCS) of all patients were measured after 1 or 2-week treatment, and Glasgow outcome scale (GOS) of them was determined 3 months later. Then the therapeutic effect in the two groups were compared.

RESULTSAfter treatment, the ICP was lower, GCS higher and GOS better in the treated group than those in the control group significantly, all showing statistical significance (P < 0.05).

CONCLUSIONXSTI has marked clinical therapeutic effect in treating patients with severe craniocerebral injury.
