Objective To investigate the clinical effect of small incision for total hip arthroplasty on osteoporosis treatment of elder patients with fracture of the femoral neck.Methods Fifty-six elder patients with femoral neck methods were selected as our subjects,who were hospitalize from Jan.2011 to Dec.2013 in Xiahuayuan Meikuang Hospital,Zhangjiakou Company Limited.They were randomly divided into the observation group (26 cases) and control group (30 cases).All patients were treated with small incision total hip arthroplasty.The patients in the observation group were given the alendronate sodium.The curative effect,hospitalization time,bone mineral density were recorded.Results The long-term efficacy of the excellent and good rate of the observation group was 96.2％ (25/26),higher than that in control group(86.6％ (26/30)),and the difference was statistically significant(x2 =4.125,P ＜ 0.05).The length of hospitalized time in observation group was (26 ± 4) d,shorter than that in the control group (35 ± 3) d,and the difference was statistically significant(t =9.102,P ＜ 0.05).The bone density of patients in the observation group was (0.64 ± 0.03) g/cm2,higher than that in control((0.61 ± 0.05) g/cm2),and there was significant difference between two groups (t =8.461,P ＜ 0.05).Conclusion The effect of small incision total hip arthroplasty combined with anti osteoporosis drugs for the treatment of femoral neck fractures in the elderly is good and worthy of clinical usage.

OBJECTIVE:To evaluate the therapeutic effect of Xuesaitong soft capsule on symptoms of TCM in patients with stroke and cerebral infraction. METHODS:112 patients were divided into 2 groups,84 cases for experimental group and 28 cases for control group using CDAS 2.0 software. Experimental group were given Xuesaitong soft capsule and stimulation agent of Yinxingye soft capsule 2 pill at a time for 28 days,tid. RESULTS:100 patients including 75 cases for experimental group and 25 cases for control group had been completed experiment. There were statistical significance in difference between 2 groups in respect of improving half paralyzed symptoms,speech lost,dizziness and quarrel skew. Above aspects of experimental group were better than control group. CONCLUSION:Xuesaitong soft capsule have sound effect on blood stasis in stroke patients in recovery period.

Objective To investigate the mechanism of Deinococcus radiodurans pprI gene in enhancing mice radioresistance to γ-rays by transfecting it in vivo.Methods The male Kunming mice were randomly divided into control group,irradiated group,pCMV-HA transfected group and pCMV-HA-pprI transfected group.The pCMV-HA-pprI plasmid contained pprI gene was injected into the muscle of mice which were exposed to total 6 Gy of γ-ray irradiation.After injection,the in vivo gene electroporation technology was used to transfect the pprI gene into the cells,and Western blot was used to identify the PprI protein,mammalian homolog protein Rad51 corresponding to recA gene downstream of pprI,and protein Rad52.Results In the muscle of the mice of transfected pCMV-HA-pprI group,the protein PprI expressed significantly at 1 d post-irradiation,but there was no expression of pprI gene 7 d post-irradiation and in other groups.In the mice of transfected with pCMV-HA-pprI,the expression of Rad51 protein was significantly increased in the lungs at 1,7 and 14 d post-irradiation,and significantly increased in the liver at 1 and 28 d post-irradiation and increased in the kidneys at 1 and 14 d post-irradition.However,there was no obvious change of Rad52 protein expression in the lungs and livers of mice in all groups.Conlusions The prokaryotic gene pprI could act on the mammalian homologisation analogues rad51 gene downstream of recA gene and then increase the expression level of protein Rad51 which results in the enhancement of radioresistance.

In order to solve the difficulties and challenges in the implementation of the original blood distribution and collection regulations caused by the expansion of hospital area, the extension of blood transfer time, the changeability of blood transfer environment, and the strain of personnel due to the increase of workload, as well as to ensure the accuracy of the information throughout blood remote verification and distribution and the safety of clinical blood transfusion, , Shanghai experts related to clinical transfusion and blood management had made a systematic study on the applicable scope and management rules of remote verification of blood distribution and collection, and formulated this Expert Consensus combined with the development status of digital, intelligent and remote communication technologies, so as to provide corresponding guidance for clinical medical institutions in line with the changes in reality.

Autologous ozonized blood transfusion(AOBT) is a therapy of re-transfusion of 100-200 mL of autologous blood after shaking and agitation with appropriate amount of oxygen-ozone in vitro. The oxidation of blood through the strong oxidation of ozone can enhance the non-specific immune response of the body, regulate the internal environment and promote health. This therapy has been increasingly applied in clinical practice, while no unified standard for the operation process in terms of ozone concentration, treatment frequency and treatment course had been established. This operation process of AOBT is primarily explored in order to standardize the operation process and ensure its safety and efficacy.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.
