Objective To understand the drug tolerance of Augmentin for Escherichia coli , Klebsiella pneumoniae spp and other pathogens Methods The MIC, MBC and bactericidal curves of Augmentin of 135 clinically isolated pathogenic bacteria were assayed The anti bacterial activity and clinical effect between Augmentin, Cefurxine, Ceftriaxone, Amoxicillin and Cefazolin were compared by MIC 50 , MIC 90 , MBC 50 , MBC 90 and modal number MIC,MBC Results Augmentin was better than the same kind of antibiotic without ? lactamase inhibitor It had a good effect for anti bacteria activity of extend spectrum ? lactamase (ESBLs) Escherichia coli and Klebsiella pneumoniae spp Conclusion Augmentin can be used for infection of ESBLs and other common pathogenic bacteria, since it has a good anti bacterial activity for most clinicaly isolated pathogenic bacteria and productive enzyme bacteria

OBJECTIVE：Analyzing the epidemic of drug risistance bacteria with extend spectrum β-lactamase(ESBLs)in children's wards to cut off the transmitting pathway and prevent the outbreak of nosocomial infections in time.METHODS：Samples，including sputum，umbilical secretion，pus，pharyngeal swab，were collected from in-hospital child patients in Departments of Newborn，Respiratory Tract Diseases，Cardiology，Nephrology，Hematology，Pediatric Surgery and ICU，then bacterial cultures and drug susceptibility test were carried out.54 strains of ESBLs E.coli and Klebsiella pneumoniae were isolated and their plasmid profiles were analysed by agarose electrophoresis.RESULTS：The percentages of ESBLs in the above-mentioned departments were 46.3，12.9，5.6，12.9，5.6，11.1，5.6 respectively.In analysis，three types of profiles were found and strains with four types of the same profile concentrated in the Newborn Department.The others were dispersed.CONCLUSION：Nosocomial infections possibly occured in the Newborn Department to some extent.

Essential palatal tremor is relatively rare in clinical practice, which manifests involuntary and rhythmic contraction of soft-palate along with auditory click. The cause is unknown and there is no specific treatment at present. This article reports a female patient with essential palatine tremor, who presented with involuntarily beating of soft palate, disappeared during sleep, had sensory tricks, and gradually developed mental and psychological problems such as anxiety disorders. After treatment with integrated traditional Chinese and Western medicine, the symptoms improved. The clinical features of the case were analyzed, relevant literature was reviewed, and the possible etiology and characteristics of the disease were explored, so as to provide reference for clinical diagnosis and treatment.

Objective To design and build a set of experimental equipment for neutron radiation irradiation by using the ²⁴¹Am-Be neutron source. Methods In the preliminary work, the spatial distribution data of the neutron energy spectrum and the gamma energy spectrum inside and outside the device were simulated by Monte Carlo method, and the changes of radiation fluence rate with spatial distribution was studied. The model of the ²⁴¹Am-Be neutron device was established, and the neutron transport process in the irradiation field was studied using the method of shadow cone, inverse square law and other data analysis methods. Results Based on the simulation results, the normalized effective does of fast neutron fluence at the measurement point is about 72.9 pSv/n, and the one of photon fluence is about 3.04 pSv/γ. The ratio of effective dose of photon fluence to neuteon is about 4.17%. Conclusion Using Monte Carlo method, a standard model of ²⁴¹Am-Be neutron source was constructed, the shadow cone design was optimized, and the feasibility of using the shadow cone conversion method to establish a standard neutron source radiation device was discussed.

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.
