International Journal of Pediatrics 2014;41(6):644-648
Objective To explore the role of mammalian target of rapamycin (mTOR) complex in the adriamycin induced the podecytes.Methods 1 μmol/L adriamycin (ADM) was used to induce mice podocytes for 24 hours and detected the apoptosis ratio,podosytes damage markers (Desmin) and the related expression of mTOR,then the role of mTOR was analysized in ADM induced podosytes.Results 1 umol/L ADM induced mice podosytes for 24 hours can make the podocytes damage.Compared with control group,podosytes activity declined(t =28.68,P < 0.001),apoptosis rate increased both early (t =10.24,P =10.24) and late (t =4.26,P =4.26),and Desmin expression increased(t =6.16,P <0.001).mTOR expression decreased in ADM group.Compared with control group,both mTOR and phosphorylation mTOR expression decreased (t =3.57,P =3.57).mTOR downstream target molecular S6K1 and 4ebpl mRNA expression decreased(t =18.28,P < 0.001).Conclusion ADM can make podosytes damage and the mechanism of ADM induced podosytes damage may be related to the decreasing mTOR and the low activity of mTOR.

Tianjin Medical Journal 2015;(8):902-904
Objective To investigate the effects of therapeutic equipment that aimed to improve cerebrovascular func?tion combined with electric standing bed on balance disorder following cerebellar infarction. Methods Fifty patients with balance disorder after cerebellar infarction were randomized into study and control groups. Agreed routine rehabilitation ther?apy including automatic standing bed and medication were given to both groups. In addition, therapeutic equipment that aim to improve cerebrovascular function were delivered to patients in study group. The effects were assessed using Fugl-Meyer balance function scale and Barthel index (BI) before and after 4 weeks of treatment. Results Study group and control group did not present difference between FM-B grade and BI before treatment (P>0.05). Both FM-B and BI were improved after treatment (P<0.05), but it improved more in study group than in control group (P<0.05). The total efficiency in treatment group is higher than that in control group (P<0.05). In the process of treatment, no obvious adverse reactions was observed. Conclusion The therapeutic equitment that aim to improve cerebrovascular function combined with automatic standing bed can improve balance disorder and daily activity after cerebellar infarction.

Aninductivelycoupledplasmamassspectrometric(ICP-MS)methodbasedonquadrupole reaction/collision ( DRC) was developed for the determination of K,Na,Ca,Mg,Al,Cu,Zn,Pb,As and Mn in food. Samples were digested with HNO3 and H2 O2 followed by dilution with ultrapure water and then analyzed directly by ICP-MS. The signal sensitivity of high concentration element ( K, Na, Ca, Mg and Al ) was suppressed easily by adjusting the voltage parameters of DRC quadrupole ( Rpa) , and the food samples could be online diluted any multiples ( i. e. from one time to million times) according to the actual need. In order to eliminate mass spectral interferences of 40 Ar35 Cl+, the operational conditions of the DRC, working with CH4 as reaction gas, were optimized for 75 As. The limits of detection for the K, Na, Ca, Mg, Al varied from 0. 013-0. 027 mg/L, and Cu, Pb, Zn, As, Mnvaried from 0. 12-0. 61 μg/L. The accurate and reliable results were obtained for validation of the ICP-MS method with food reference material according to the national standard GBW10023 , GBW10015 , GBW10018 , GBW10017 , GBW10019 and GBW10024 . As the routine method in our laboratory, the satisfactory results indicate that it has great potential for the determination of low and high concentration level elements by one single analysis in various samples.

Objective:To probe into if human molecular adjuvant hC3d3 promote the immunogenicity of hCG? antigen to human immuno-competent cells on the basis of fusion protein.Methods:The isolated B cells, the combination of B cells and T cells, PBMC and Raji cells were treated in vitro respectively with 1, 10 and 100 nmol/L hCG?, hCG?-hC3d3 or PWM for 8-12 days. The cell proliferation was determined by incorporation of [3H] thymidine. The Ig levels in the 12-day culture supernatants were measured by indirect ELISA. The Ig-secreting cells in the 10-day cultured lymphocytes were detected by the enzyme-linked immunospot(ELISPOT) assay.Results:It was found that the proliferation of B cells, the combined B and T cells, PBMC and Raji following exposure to hCG?-C3d3 fusion protein was significantly higher than that of hCG? alone. The levels of total Ig the in 12-day culture supernatants of B cell, the combined B and T cells, and PBMC treated with 100 nmol/L hCG?-C3d3 fusion protein were 4-fold, 10-fold and 10.85-fold more than that of hCG? alone. The Ig-secreting cells were significantly increased after treated with hCG?-C3d3 fusion protein compared to the hCG? alone.Conclusion:The human molecular adjuvant hC3d3 improves the immunogenicity of hCG? in human immuno-competent cells if fused to the antigen.

Objective To improve the outward appearanee in toe-to-hand transfer,a reshaped procedure of second toe was studied. Methods In reconstructing a finger with second toe transfer,a piece of flap from the fibular side of the second toe,or/and a H-shaped flap from the tibial of great toe were designed and transferred to the volar side in order to obliterate the constriction below the toe pulp. Results In 17 patients,22 fingers reconstructed with these procedure,ouly one rotation flap necrosis partly.The appearance of the newly reconstructed thumbs and fingers were improved,the pulp of reconstructed finger was similar to a natural finger, the narrow neck of second toe was well-stacked,and the interpbalangeal joint was straighten. Conclusion Reconstructed finger with this reshaped second toe is similar to a normal finger.

To popularization and improvement of on-the-spot rescueability is a vital means to reduce the accidental disability rate and the mortality rate,which is also a prospective concept of health.To popularize on-the -spot rescue knowledge and to improve self and mutual medical aid is a strongly public welfare and is the manifestation of social responsibility as well as respect for life.Based onthe investigation of on-the-spot rescue ability among three higher vocational college students in Shaanxi,this paper pointed out that the popularity rate of on-the -spot rescue knowledge was low among higher vocational college students,which no longer kept pace with the demand of social development and occupational requirement.It also analyzed the importance and urgency of improving higher vocational students'on-the-spot rescue ability from the perspective of social ethics.Strengthening the propaganda and training self-rescue skills might be a possible way to enhance students' on-the-spot rescue ability.

From the Chinese medicine point of view on the physiological functions of healthy atmosphere and vitality, healthy atmosphere and vitality of the relationship, we can know that healthy atmosphere and vitality has important role in the life activities of the body. They complement each other. In the pathogenesis of AIDS, AIDS epidemic poi-son has the characteristics of wounding healthy atmosphere. When it attacks the body upright, vitality will be injured firstly. Because of that it is inextricably linked with the characteristics of the AIDS epidemic poison and vitality physiological functions. Therefore, AIDS epidemic poison attacks healthy atmosphere and vitality co-exist, the injury of healthy atmosphere and vitality is throughout the whole process of AIDS .
