Pulmonary cyst is a relatively common benign lesion.It is easy to be misdiagnosed when the cyst complicated with infection.Tnis paper reported a case of a giant traumatic pulmonary cyst (diameter 10 cm) combined with chronic infection.Firstly,the patient was diagnosed as cholesterol pleurisy after undergoing thoracoscopic biopsy.With repeated pleural effusion,the patient was scheduled for right anterolateral thoracotomy,which showed a thin-walled cyst (10 cm in diameter) attached to parietal and diaphragm,with the stem of cavity originated from the right lower lobe after the cyst cavity was dissociated.Pathological examination revealed that it was apseudocyst,which could be diagnosed as traumatic pulmonary cyst combined with chronic infection according to history of trauma.After undergoing right lower lobectomy and stripping of fiberboard,the prognosis was good.Traumatic pulmonary cyst,which was discovered interval 10 years after chest trauma,was rare.Traumatic pulmonary cyst combined with cholesterol cystic fluid was very rare.Huge pulmonary cyst complicated with infection was easily misdiagnosed as loculated pleural effusion.Therefore,to be correct diagnosis and treatment,clinician must carefully ask medical history.In addition,early image examination should be considered in those patients with chest trauma whether there are clinical symptoms or not.

Objective By studying the different blood volume blood donors machine adopt platelet product aggregation,platelet content,the machine adopt circulating volume,etc,analysis of different blood volume machine adopt donors on appropriate conditions.Methods The base material of randomly selected 307 blood donors,through blood related index in the study of circulating volume,blood volume,gender,platelets,Hct,Pct count before collection,machine adopt of platelet aggregation and the relationship between the acquisition time;different blood volume,blood platelet count grouping machine adopt the different of platelet aggregation rate,different amount of platelets collect blood volume group,the comparison of blood circulation.The use of statistical software SPSS 17.0,data analysis,analysis including multiple regression analysis,chi-square test,t test,etc.Results 1)The lower count of platelets,Hct,Pct count before collection,the longer the acquisition time,and gender and Pct has nothing to do with the acquisition time the longer the acquisition time,the higher the machine adopt the possibility of platelet aggregation.2)Low blood volume and low platelet count group,machine mining platelet aggregation rate is higher.3)Machine adopt donors of blood volume is higher,the machine adopt the platelet collection amount,the more and the less blood circulation.Conclusion According to the different blood volume blood donors check-up indicators,further carries on the reasonable analysis,optimized machine mining scheme,especially to reasonable arrangement of low blood volume blood donors,so as to improve the quality of platelet collection.

Objective To analyze the clinical manifestation caused by local injections of botulinum toxin type A for cosmetic reason and the effect of antitoxin for adverse reaction.Methods Diagnosis and treatment process of 40 patients were retrospectively analyzed for adverse reactions due to botulinum toxin injections for beauty.Severe adverse reaction was assessed according to the patients clinical manifestation and the nervous system of physical assessment.The patients were given symptomatic treatment,observation or antitoxin therapy.Results Adverse reactions developed in 40 patients were mainly the nervous system abnormalities.Dyspnea developed in four cases.34 cases (85 ％) were given symptomatic treatment.4 cases (10 ％) were given botox treatment,and the patients were followed up for 1-3 months.The patients fully recovered to normal and did not leave any neurological sequelae.Conclusions The management of type A botulinum toxin injections should be strengthened.In case of poisoning,antitoxin therapy should be given as early as possible.

Through comprehensive and systematic collection of existing evidence,systematic review adopts clinical epidemiological methods,strictly evaluates the quality of evidence,qualitatively or quantitatively combines research results,and finally provides a reliable basis for solving a focused clinical problem.The number of systematic reviews has increased rapidly.With references to the Checklist,this review discussed the typical issues with current systematic reviews in nursing,and highlighted the crucial components for reporting systematic reviews at every essential step.
