5.Analysis of stability and healing on minimally invasive osteotomy for the treatment of hallux valgus.
China Journal of Orthopaedics and Traumatology 2016;29(3):228-231
To treat hallux valgus, minimally invasive osteotomy on 1st metatarsal neck,immobilization with "8-shape" bandagev was performed, and the effect was definited. The principles of osteotomy stability were analyzed from the osteotomy position, methods, direction and angle. The grinding drill was used to increase friction coefficient between the ends of osteotomy. Correct direction of osteotomy and suitable angle were the key point of stability. The immobilization with "8-shape" bandage complied with the principle of elastic fixation created the conditions for the slight movement of the osteotomy ends. Compared with internal fixation ,it was better on osteotomy healing,and the osteotomy ends were stable and healed with cartilage

6.Interpretation of standards on training and evaluation of urine analyzers in grass-roots medical unit
Chinese Medical Equipment Journal 2017;38(5):135-137
Objective To analyze the training and evaluation standards on urine analyzers in the grass-roots medical unit.Methods The applicability,requirements,subject setup and items of the standards as well as the requirements of evaluation scoring chart were expounded in detail,and the related elementary knowledge was analyzed including the structure,working principle,installation and adjustment,operation,application,maintenance and etc of the analyzer.Combined personnel with the equipment was suggested to ensure the accuracy and high efficiency of the test result.Results The interpretation of the standards contributed to enhancing the quality of medical equipment training and the ability of practical support,and facilitated the examiner to perform annual evaluation with the scoring chart.Conclusion It is necessary to grasp accurately the connotation of the standards,to improve the quality of medical equipment training and to enhance combat support capability for the grass-roots medical unit and examiner.

A combination vaccine which consists of ≥2 immunogens is intended to provide protection against two or more diseases or against multiple serotypes of a single disease. The use of combination vaccines decrease the number of vaccine injections in the regular immunization schedules. However,the development of combination vaccines is more complicated than monovalent vaccines,preservatives and adjuvants used with one component may alter the potency of other components. Physical,chemical,and biological interactions between the components of combination vaccines must be considered to avoid detrimental effects on safety or efficacy. Therefore combination vaccines present unique challenges for product evaluation. This paper presents a review of research application status,the evaluation of effectiveness and safety,as well as development prospects on combination vaccines.

Objective To investigate the effect of psychological stress on serum iron concentration of SD rats and its mechanism. Method SD rats were randomly divided into four groups: control group (CG), psychological stress 1w group (PG 1w) and 2w group (PG-2w), and psychological stress 2w with 1w free group (PG 2w-1w). The animal model of stress was tested for 1w, 2w, and 2w with 1w free from stress. The iron concentration of serum, liver, spleen and the expression of liver hepcidin were detected by atomic absorption spectrometry and Western blot respectively. Result (1) Compared with control group, serum iron concentration of rats under stress decreased. (2) Free of psychological stress 1w later, serum iron concentration was not significantly changed. (3) Iron concentration of liver and spleen was increased significantly compared with control group, and the expression of liver hepcidin was also increased. Conclusion Psychological stress may cause serum iron of rats to decrease obviously, and it was restored after 1w free from psychological stress. The mechanism is supposed to be increase of iron storage in liver and spleen by hepcidin in rats under psychological stress.

AIM: To investigate the influence of Astragalus Injection on morphology,cell cycle and oxidative stress of rat's glomerular mesangial cells(GMC) cultured with advanced glycation end products(AGEs). METHODS: GMC were incubated in culture medium containing AGEs in the presence of Astragalus Injection and aminoguanidin for 48 h.At the same time,the normal and control groups were established.Then the cultured GMC was stained by mixed fluorescence liquid and observed under fluorescence microscope.Cell cycle of GMC was analyzed using flowcytometry.The activity of SOD、MDA and GSH-PX in GMC supernatant were measured by test kit.The level of ROS was detected by flowcytometry. RESULTS: Morphology analysis showed that the morphology and structure of normal GMC were normal.The structure of most cells in AGEs was unclear,cell counts increased markedly and they grew intensively.Cell cycle analysis showed that cell percentage of S phase increased and G_0/G_1 reduced.The level of ROS,MDA remarkably increased,and SOD,GSHPX activity reduced.Whereas Astragalus Injection was added,cell morphology tended to be basically normal and cell counts decreased,the percentage of S phase also decreased.The level of ROS,MDA and the SOD,GSH-PX activity restored in comparison with the control groups. CONCLUSION: Astragalus Injection can prevent GMC from lesion caused by AGEs.Astragalus Injection may protect GMC from retarding the progression of diabetic nepropathy by partially inhibiting the occurrence of oxidative stress.
