Objective To compare the efficacy of internal fixation with non-operative treatment of traumatic flail chest combined with sternal fracture.Methods A retrospective review was made on 102 patients with traumatic flail chest combined with sternal fracture treated from January 2007 to January 2014.There were 71 patients in operation group and 31 patients in non-operation group.Operation group was allocated to pure titanium rib plating (Group Ⅰ,22 cases),porous titanium screw fixation (Group Ⅱ,20 cases),and nickel-titanium memory alloy sternal rib plating (Group Ⅲ,29 cases).Rib traction was performed in non-operation group.Clinical results and incidence of complications were compared between the two groups.Results At 24 and 72 hours,operation group was superior over non-operation group with regard to HR [(100.4 ± 9.5) times/min vs (105.2 ± 10.1) times/min,(92.1 ± 9.9) times/min vs (102.1 ± 9.2) times/min],MAP [(97.7 ± 14.5) mmHg vs (91.0 ± 13.3) mmHg,(112.5 ± 15.2) mmHg vs (93.1 ± 13.8)mmHg] and CVP [(7.8 ±3.7)cmH2O vs (9.4 ±3.8)cmH2O,(6.2 ±2.9)cmH2O vs (9.1 ±3.2) cmH2 O] (P < 0.05).Duration in ICU [(5.1 ± 0.8) days vs (9.3 ± 1.1) days],ventilation time [(4.5 ±1.0)days vs (8.2 ± 1.4)days],hospitalization time [(14.6 ±3.5)days vs (23.3 ±4.4)days] and incidence of complications were significantly lower in operation group than in non-operation group (P < 0.05).Two months after discharge,tidal volume (VT) [(0.52 ±0.04)L vs (0.40 ±0.03)L],inspiratory capacity (IC)[(1.99 ±0.45)L vs (1.22 ±±0.33)L],forced vital capacity (FVC) [(3.52 ±0.51)L vs (2.44 ±0.42)L],total lung capacity (TLC) [(5.41 ±0.82)L vs (3.72 ±0.56)L] and forced expiratory volume in one second (FEV1) [(2.80 ± 0.43) L vs (1.95 ± 0.50) L] showed significantly better results in operation group than in non-operation group (P < 0.05).Operation time,intraoperative bleeding and daily drainage volume were (38.8 ±9.2)min,(43.5 ±7.6)ml and (10.9 ± 1.1)ml in Group Ⅱ versus (62.5 ± 10.1)min,(100.0 ± 10.5) ml and (26.8 ±3.1)ml in Group Ⅰ and (49.3 ±9.6)min,(61.4 ±8.3)min and (19.8 ±1.6)ml in Group Ⅲ (P < 0.01).Conclusion For traumatic flail chest combined with sternal fracture,the internal fixation should be done as early as possible so as to reduce incidence of complications.Relatively,porous titanium screw fixation has better clinical outcome.

microRNAs function as effective molecules in regulation of many biological functions of organisms; in most case they regulate gene expression moderately. Emerging evidence suggests that microRNAs play a key role in the regulation of immunological functions including innate and adaptive immune responses. The research on microRNAs would be helpful in elucidation of the mechanisms of human immune system and in development of potential therapies based on microRNAs.

Objective To provide reference for anti-infection drugs in Zunyi area by analyzing the etiological characteristics of children with severe pneumonia.Methods The sputum, throat swabs and serum of children with severe pneumonia in pediatric intensive care unit of our hospital from January 2014 to December 2015 were collected in this study.The pathogen species which caused severe pneumonia were detected and identified by the method of pathogen culture,and typical pathogens were detected by RT-PCR and indirect immunofluorescence.Results A total of 337 children with severe pneumonia were included,the pathogen positive rate was 86.65%(292/337).The rate of viral infection(37.32%)was the highest,followed by bacterial infection accounting for 28.42%,then the mixed infection accounting for 27.74%,and the mycoplasma pneumoniae infection accounting for 6.50%.The respiratory syncytial virus type B accounting for 28.44% was the most common in viral infection,and there were significant differences in age distribution(P<0.05),the children under 3-years-old,especially the infants under 1-year-old had the highest susceptibility.Viral infection had certain seasonality,compared with spring and winter,autumn and winter(November to April) had higher viral detection rate and the difference was statistically significant(x2=29.28,P=0.001).The escherichia coli was the most common in bacterial infection,accounting for 21.69%.Klebsiella pneumoniae,Escherichia coli were more common in neonates and infants under 1-year-old,Haemophilus influenzae occured in 1~3 years old children,Streptococcus pneumoniae infection could occur in any age.Conclusion Viral infection is the most common pathogen in children with severe pneumonia in Zunyi area followed by bacterial infection,which is more common in children under 1-year-old,and with the high incidence in autumn and winter.Bacterial infection is more common in children over 3 years of age.Bacterial and viral mixed infection is common in children under 3 years of age,especially in children under 1-year-old.

Objective To analyse the diagnosis and treatment of testicular torsion. Methods The clinical data of 66 cases of testicular torsion were retrospectively analysed. Results Among the 66 cases,32(48.5%) paid the first medical visit within 10 h,and 24(36.4%)were confirmed diagnosis at the first visit.False negative results occurred with color Doppler flow imaging(CDFI),and 8 testicles were damaged due to the false negative diagnosis.Thirty-three patients without prophylactic contralateral orchidopexy were followed up for 6 months to 20 years,and one experienced recurrent torsion. Conclusion The testicular torsion must be considered when a sudden acute scrotum pain is occurred.Testicular damage is closely related to the torsion time,and delayed medical intervention contributes to the testicular damage.Highly suspected cases should be performed surgical exploration timely due to the false negative results with CDFI.Prophylactic contralateral orchidopexy is recommended.

Objective To evaluate the effect of point-of-care hemoglobin/hematocrit (POC HGB/HCT) devices and intraoperative blood salvage on the amount of perioperative allogeneic blood transfusion and blood conservation in clinical practice.Methods A total of 46 378 medical records of 22 selected hospitals were reviewed. The volume of allogeneic red blood cell and plasma, number of patients transfused, number of intraoperative autologous blood salvage, total volume of autologous blood transfusion, and amount of surgery in the year of 2011 and 2013 were tracked. Paired t-test was used in intra-group comparison, while t-test of two isolated samples carried out in inter-group comparison. P<0.05 was defined as statistically significant difference.Results In the hospitals where POC HGB/HCT device was used (n=9), the average allogeneic blood transfusion volume per 100 surgical cases in 2013 was significantly lower than that in 2011 (39.86±20.20 vs. 30.49±17.50 Units, t=3.522, P=0.008). In the hospitals without POC HGB/HCT meter, the index was not significantly different between 2013 and 2011. The average allogeneic blood transfusion volume was significantly reduced in 2013 than in 2011 in the hospitals where intraoperative autologous blood salvage ratio [autologous transfusion volume/(autologous transfusion volume+allogeneic transfusion volume)] was increased (n=12, t=2.290, P=0.042). No significant difference of the above index was found in the hospitals whose autologous transfusion ratio did not grow.Conclusion Intraoperative usage of POC HGB/HCT devices and increasing autologous transfusion ratio could reduce perioperative allogeneic blood transfusion.
