This paper analyzes the amputation reasons of 74 cases on lower limb amputator, recovery condition after fitted artificial limb and fitted time. The result shows; the most common reason on lower limb amputation in industrial accidents and traffic accidents; patients' whole function almost all rise from 3 level to 4 level; Amputators basically can conduct their daily life. Also the paper discusses some social etyical problems such as reducing industrial accident and traffic accident, strengthening the support and help on maimed persons by early fitting temporary artificial limb.

The anti-DNP and anti-OA IgE antibody responses of six strains of mice immunizedwith DNP-OA conjugate in presence of A1(OH)_3 adjuvant was investigated.Signifi-cant differences of the magnitude of serum IgE were found in anti-hapten and anti-carrier responses among strains.The primary and secondary anti-DNP and anti-OAIgE antibodies were elicited in NIH,BALB/c and DBA/2 mice after immunizationwith 1?g of DNP-OA.Among them NIH mice was the highest responder,whereasLACA,C3H and B6D2F1 mice were poor or nonresponders.In comparison the IgEresponse in BALB/c mice immunized with 1?g and 10?g of DNP-OA,the former de-monstrated a latency of primary response,but two groups had a very similar PCAtiters after 4 weeks of immunization.On the other hand,LACA mice gave a dose de-pendent IgE response.Profound primary and secondary IgE antibody responses can beonly seen in mice injected with 10?g of DNP-OA and PCA titer of anti-DNP washigher than that of anti-OA IgE antibody.However,no difference of IgE antibodylevels in NIH mice can be found between groups immunized with different doses.DNP_(4.7)-OA primed mice gave higher IgE response than that of mice immunized withDNP_3-OA.A prevailing anti-hapten IgE response was observed when higher dose ofDNP-OA conjugates was injected.

Hie morbidity and mortality of bladder cancer are both the highest among urinary cancers in China. As a critical component of epigenetics, DNA abnormal methylation plays an important role during the occurrence and progression of bladder cancer. Recently, researchers focusing on the DNA methylation in bladder cancer have done much on it The results are of great clinical significance for screening,diagnosis and therapy of bladder cancer.

Ph-like acute lymphoblastic leukemia (Ph-like ALL) involves various genomic alterations associated with high risk factors and poor clinical outcome, such as IKZF1, CRLF2, JAK1/2, EBF1-PDGFRB, ATF7IP, EPOR, SH2B3.JAK/STAT pathway and PI3K/mTOR pathway are likely to be the targets of Ph-like ALL.Here,the above genomic alterations and treatment progress are reviewed.

Bronchial asthma is one of the most common chronic respiratory diseases in children.Airway remodeling that makes asthma difficult to control is an important pathological progress of asthma.Toll-like receptors (TLR), a kind of pattern recognition receptors, are expressed in a variety of human airway structure cells, such as airway epithelial cells, smooth muscle cells, mucus gland cells, etc.It is reported that TLRs play important roles in the regulation of airway remodeling in asthma.This article briefly summarizes the role of TLR in airway remodeling of asthma.

Objective To discuss the curative effects and clinical safety of high -dose glucocorticoids (GCS)combined with short -range hormone therapy for myasthenia gravis(MG).Methods The clinical data of 68 patients with MG were retrospectively analyzed.They were divided into the control group and the observation group (34 cases in each group)according to different treatment methods.The control group was treated by high -dose GCS combined with long -term hormone therapy,while the observation group received large doses of GCS short -range hormone treatment combined with other immunosuppressive therapy.Before and after treatment,curative effects and adverse reactions of the two groups were recorded and compared.Results The onset time of the control group and the observation group was respectively (7.8 ±3.5)days,(8.2 ±4.2)days;Before treatment,and after 4 weeks,8 weeks, 12 weeks treatment,the clinical absolute scores of the control group were (24.7 ±10.5)points,(15.4 ±6.3)points, (6.8 ±5.4)points,(7.1 ±4.5 )points,which of the observation group were (25.2 ±11.1 )points,(16.9 ± 7.1)points,(7.4 ±4.8)points,(8.3 ±5.5)points.The onset time and clinical absolute scores of the two groups had no statistical differences(t =0.978,0.925,0.897,1.213,all P >0.05);After 4 weeks of treatment and 12 weeks of treatment,the total effective rates in the control group were 85.3%,94.1% respectively,which of the observation group were 76.5%,91.2% respectively,the two groups had no statistically significant differences (χ2 =0.856, 0.216,all P >0.05);The incidence rate of adverse reactions in the control group (38.2%)was significantly higher than 14.7% in the observation group(χ2 =4.836,P <0.05).Conclusion Large dose of GCS combined with short-range hormone has adequate curative effects compared with large dose of GCS long -range hormone for the treat-ment of myasthenia gravis,but it had the lower incidence of adverse reactions,which is worthy of clinical promotion.

Objective:There are many different kinds of biological safety cabinets, it make some difficulties in the allocation. Scientific selection which based experimental requirements choose the right equipment match experiments, it can effectively prevent the spread of pathogenic microorganisms of operation personnel damage and environmental pollution.Methods: According to its working characteristics, different laboratory levels, detection items and actual operation of dangerous levels of pathogenic microorganisms, to determine the matched biological safety cabinet.Results: According to the different experiments correctly, choose the appropriate biological safety cabinet, bio-safety has been obviously improved, the incidence of adverse events decreased from 12% to 3%; the experimenter's security has improved.Conclusion: Through the use of biological safety cabinet clear and selection method, can not only improve biological testing of safety consciousness, but also strengthen the biological safety standardization, institutionalization and standardization of the management mechanism, avoid the use of biological safety, improve the quality of the efficiency of laboratory work and experiment, laboratory personnel biological safety.

[Objective]To discuss the treatment to post-apoplexy depression with acupuncture of strengthening brain and regulating mind.[Method] Select 60 cases;randomly divide them into acupuncture group and western medicine group with 30 cases in each.Both accept basic therapy,the acupuncture group is added with acupuncture of strengthening brain and regulating mind,the other with fluxetine;for successive 4 weeks make scores to HRMD mete table,nerve function lack degree and daily life Barthel index.[Result] Both scores had changes after treatment,however the acupuncture group was better than another group,with marked cure effect,meanwhile with quantity-efficacy relationship.[Conclusion] Acupuncture of strengthening brain and regulating mind can relieve depression,promote nerve function recovery and improve life quality.

The latest study shows that the expression abnormalities of programmed death 1/programmed death ligand 1 (PD-1/PD-L1) signaling pathway in a variety of solid tumor tissues and cells are related to disease progression and poor prognosis, and directly involve in tumor immune escape, becoming the recent focus. With the further research, PD-1/PD-L1 signaling pathway in blood diseases, for example, in the development of lymphoma, is catching more attention gradually. The signaling pathway not only is associated significantly with malignancy, progression, recurrence of lymphoma and prognosis of patients, but probably becomes a new target for cancer immunotherapy. This paper summarizes the expression and research status of the biological characteristics and mechanism of PD-1/PD-L1 signaling pathway in lymphoma, in order to provide a new way for lymphoma treatment.

Hg.The health risk of gene toxic substances was more distinct than that body toxic substances.(2)The total health risk of all pollutants in drinking water was 7.18?10-5a-1 in 2003,2.12?10-4a-1 in 2004 and 2.28?10-4a-1 in 2005,all of which exceeded 5.0?10-5a-1,the value recommended by ICRP,and greatly exceeded the standards recommended by the Sweden Bureau of 2 Environment Protection and the Holland Ministry of Building and Environment Protection.Conclusions:There is reference value in our research for risk management of drinking water resources and water enviroment poretcting measures.
