OBJECTIVE To investigate the hearing level of deafmute children in three deafmute schools in Nanning,Liuzhou and Guilin cities and reveal the importance of early diagnosis and intervention.METHODS The pure tone hearing thresholds of 0.5,1,2,4 kHz of 357 deafmute children in three deafmute schools were recorded. The disability grade was evaluated according to the average threshold of 4 frequencies.RESULTS A total of 410 students were in the three deafmute schools.There were 248 male and 162 female with an age ranged from 2 to 27 years(14.5 years). The number of hearing disability grade fromⅠtoⅣwere 232(65 %),64(18.0 %),48(13.5 %)and 10(2.6 %)respectively,and 3 children(0.9 %)could not graded the hearing disability.Sixty one children (17.0 %)with light or moderate hearing loss missed their optimal opportunity of hearing and speech rehabilitation.CONCLUSION The results reveal the importance of early diagnosis and intervention of hearing loss.

Tumor microenvironment plays a crucial role in neoplastic evolution process as it may provide functional interactions between neoplastic and non-neoplastic cells involved in tumor invasion,metastasis and angiogenesis,which implies that it can be regarded as a novel target for the antitumor therapy of polysaccharides.This review focuses on the protumor variations existing in tumor microenvironment,such as growth factors,immunosuppressive factors,proteases,glycoproteins,etc.,which may offer possible mechanisms of polysaccharides on the regulation of their corresponding functions.

BACKGROUND:The power output of the human joints depends on the activation of agonists and antagonist muscles around the joints, and the antagonist muscle is involved in physical activity in a co-activated manner, thereby helping to maintain joint stability. But there are less reports on the central nervous system strategies of antagonist co-activation under different muscle contraction modes. OBJECTIVE:To observe the characteristics and differences of surface electromyography (sEMG) of agonists and antagonist muscles of the knee joints during maximal and submaximal isokinetic exercises until fatigue. METHODS:Sixteen students were enroled, who developed the right knee joint fatigue induced by the Biodex isokinetic equipment, and simultaneously sEMG activities of vastus medialis, vastus lateralis and biceps femoris were recorded by the myoelectrical equipment. The RMS (%) and mean frequency were selected to analyze sEMG characteristics. RESULTS AND CONCLUSION:In the maximal isokinetic fatigue, the peak torque was decreased by 40.3% (P < 0.05) and the sEMG activity of agonists gradualy increased and then declined, but the sEMG activity of antagonists kept constant. In the submaximal isokinetic fatigue, the peak torque was decreased by 40.0% (P < 0.05), the sEMG activity of agonists gradualy increased (P < 0.05), and however the sEMG activity of the antagonists initialy increased and then decreased. The RMS and mean frequency of vastus medialis and lateralis as antagonists at selected reciprocal contractions showed no significant changes (P > 0.05). These results suggest that in the different intensities of isokinetic fatigue, the central nervous system employs different neural strategies on agonists and antagonists.

Objective To investigate the myocardial remodeling inhibition effect of bisoprolol combined with trimetazidine in the treatment of hypertensive myocardial hypertrophy.Methods 86 cases with hypertension and cardiac hypertrophy in Lingwu People’s Hospital of Ningxia from June 2015 to June 2016 were selected and randomly divided into two groups,43 cases in the control group received routine clinical treatment,43 cases in the experiment group received more with bisoprolol combined with trimetazidine treatment.Blood pressure,ultrasonic cardiogram,levels of serum TNF-α, MMP3 and CRP were compared before and after the treatment.Results Compared with before treatment,levels of blood pressure,IVST,LVPWT,LVMI, MMP3,TNF-αand serum CRP significantly decreased after treatment,and compared with the control group,levels of blood pressure,IVST,LVPWT, LVMI,MMP3,TNF-αand serum CRP in the experiment group were lower,the differences were statistically significant (P<0.05),and the effective rate in the experiment group was higher than the control group ( P<0.05 ) .Conclusion Bisoprolol combined with trimetazidine can effectively inhibit the remodeling of hypertension in patients with myocardial hypertrophy,has good clinical efficacy.

Objective To explore the effectiveness of visual feedback in retraining upper limb function after stroke.Methods Sixty-one hemiplegic stroke patients were randomly assigned to a treatment group (31 cases)which received motion training using visual feedback in addition to routine neurodevelopment treatment and a motor relearning program,and a control group (30 cases) which received only the neurodevelopment treatment and a motor relearning program.The Fugl-Meyer assessment (FMA) and the modified Ashworth scale (MAS) were used for as-sessment before treatment and after 4 weeks of treatment.Results After 4 weeks of treatment,the FMA and MAS scores of both groups had improved significantly,as had the strength of the forearm flexors.The improvements were significantly greater in the treatment group than in the control group.Conclusion Motion training with visual feed-back can alleviate upper limb spasticity after stroke significantly better than routine rehabilitation alone.

Oxidative stress and inflammation are two main factors in the progress of diabetic nephropathy(DN) and its complications. NF‐E2 p45‐related factor (Nrf2) is a crucial transcriptional factor which manipulates downstream genes that encode some antioxidant enzymes and phase Ⅱ detoxifying enzymes ,to maintain the redox homeostasis and cellular detoxification response. Therefore ,more and more researchers are focusing on the role of Nrf2 in DN. In this review ,the detailed role of Nrf2 in DN will be discussed. Hopefully ,our work can epitomize recent research progress and provide novel clues for diabetic nephropathy prevention and treatment.

Objective To investigate the curative efficacy of buyang huanwu decoction in combination with cyclophosphamide in treating patients with Takayasu arteritis(TA)at active stage and its improvement on vascular endothelial injury.Methods 88 patients with TA at active stage who received therapy in The Hospital of Beijing Armed Police Corps from January 2015 to April 2016 were selected as research objects.According to therapeutic schemes,those patients were divided into the control group(n=42)and the observation group(n=46).The control group was given cyclophosphamide,while the observation group was given cyclophosphamide in combination with buyang huanwu decoction.Then,the total therapeutic efficacy ratio,laboratory-related indices and indices of vascular endothelial injury were compared between the two groups.During the treatment,incidence of adverse reactions were compared.Results The observation group had a total therapeutic efficacy ratio of 89.1％,which was statistically higher than that of 71.4％in the control group(P<0.05).After the treatment,in comparison with the control group,laboratory-related indices of erythrocyte sedimentation rate(ESR),C reactive protein(CRP)and vascular endothelial injury indices of vascular endothelial growth factor(VEGF),endothelin-1(ET-1)in the observation group were statistically lower(all P<0.05).During the treatment,the incidence of adverse reactions in the observation group was 26.1％,which was statistically same with that of 21.4％in the control group.Conclusion Cyclophosphamide in combination with buyang huanwu decoction is effective for patients with TA at active stage with a high total therapeutic efficacy ratio.And it can significantly improve laboratory-related indices and vascular endothelial injury without increasing incidence of adverse reactions.

Objective To study the influences of risk factors on the 2-week mortality in patients with acute cerebral hemorrhage.Methods From January 2004 to June 2007,a total of 65 patients with intracerebral hemorrhage in Beijing Red Cross Hospital were studied.Logistic regression was performed to analyze the relationship between prognostic factors and 2-week mortality.These factors included sex,age,volume of hemorrhage,location of hematoma,the highest body temperature in the first 24 h,and consciousness state on admission etc.Results The in-hospital mortality in 2 weeks was 18.5%(12/65).The volume of hemarrhage,body temperature and consciousness state were probably significant factors.Conclusion The increasing body temperature in the first 24 h and the unconsciousness may be the main risk factors which are associated with high 2-week hospital mortality in patience with intracerebral hemorrhage.

Objective To investigate the mental health and personality of soldiers operated inside and outside tunnels,and explore the necessity and particularity of mental training.Method One hundred and four soldiers worked inside tunnel and 88 outside tunnel were tested by Symptom Checklist 90(SCL-90) and Eysenck personality questionnaire(EPQ),and the results were analyzed statistically.Result With an exception of phobia,the SCL-90 scores of most factors were significantly higher in the soldiers worked inside tunnel than outside tunnel(P0.05) on EPQ-E and EPQ-P scores.Some of SCL-90 index scores showed positive correlation with EPQ-P and N dimension scores,and negative correlation with EPQ-E dimension score(P0.05).Conclusion Personality feature is an important factor that influences the mental health of soldiers worked inside tunnel.It is important to adopt appropriate mental training and improve the adaptability of soldiers to the military environment.
