Purpose To compare the CT features of hepatic angiomyolipoma (HAML) and primary hepatocellular carcinoma (HCC) and improve diagnostic accuracy for HAML. Materials and Methods The CT findings of 9 patients with HAML confirmed pathologically and 20 patients with HCC were retrospectively analyzed in terms of lesion location, appearance, size, margin, CT value at each phase, cirrhosis and vessel presence inside tumor. Results Mean CT value on plain scan and at arterial phase on contrast enhanced scan of HAML was significantly lower than that of HCC (t=-2.885, P<0.05;t=-3.307, P<0.01). At portal vein phase, difference in CT value showed no statistic significance (t=-0.293, P>0.05). CT value on plain scan and at arterial phase of both HAML and HCC was not significantly different (t=1.289, P>0.05) whilst that at portal vein phase was significantly different (t=2.516, P<0.05). Central vessels were shown in 7 cases of HAML and 3 cases of HCC, pseudocapsule appeared in 1 case of HAML and 13 cases of HCC with statistical difference (χ2=10.828, 7.219;P<0.01). Conclusion CT scan of HAML reveals the component of fat and presentsfast in and slow outpattern, large shadow of vessel and absence of capsule on contrast enhanced scan, which can be helpful in the differential diagnosis from HCCs.

Objective To investigate the clinicopathological features and prognostic factors in patients with low grade glioma. Methods Eighty- seven patients with low grade glioma confirmed by cytological examination were retrospectively analyzed. Results Among 87 patients, male accounted for 62.1%(54/87), and the average age was 36.2 years. The average followed- up time was 51.4 months (3-135 months), and 5 cases were lost in follow-up. The follow- up rate was 94.3% (82/87). The 3- year survival rate was 84.1%, and the 5- year survival rate was 66.7%. The 3- year survival rate was related to clinical symptoms, maximum diameter of tumor and the extent of resection (P<0.01 or<0.05);and the 5- year survival rate was related to years, Karnofsky score, clinical symptoms, maximum diameter of tumor, the pathology classification and extent of resection (P<0.05 or<0.01). Conclusions Low grade glioma is more common in male patients and patients under the age of 40 years. Age below 40 years, Karnofsky score ≥ 70 scores, only epilepsy symptom, tumor diameter below 6.0 cm, oligodendrogliomas, complete resection or subtotal resection are positive prognostic factors. Postoperative radiotherapy can reduce the rate of tumor progression.

Objective To explore the role and effectiveness of flexible fiberoptic brochoscopy ( FFB) in critically ill children with continuous invasive respiratory support. Methods From July 2014 to June 2017,135 critically ill children with severe pneumonia had received continuous invasive respiratory sup-port and undergone FFB in the pediatric intensive care unit( PICU) of our hospital. These patients were en-rolled into the therapy group. Another 104 severe pneumonia patients who had not received FFB were enrolled into the control group. Clinical characteristics of both groups were collected and compared. Results No sig-nificant differences were detected in patients′gender, age, PCIS, usage of antibiotics, and the levels of CRP and PCT assayed at the time of admission to PICU between the therapy group and control group(P>0. 05). The positive rate of bacteria culture of the bronchoscopic lavage was 78. 52%( 106 cases ) in the therapy group,and it was significantly higher than that in the control group(60. 58%,63 cases) (χ2 =5. 681,P <0. 005). For 106 cases in the therapy group,117 bacteria strains were identified,while there were 72 bacteria strains found in 63 cases with positive bacteria culture in the control group. Gram negative bacteria were the most common type,followed by Gram positive bacteria. The third most common pathogenic microbes were fungi,with a significantly higher frequency in the therapy group. No significant differences were found in PaO2 and oxygenation index between both groups before FFB. However,in a half hour after FFB,the PaO2 and oxygenation index significantly increased in the therapy group,and higher than those in the control group (P<0. 005). The levels of CRP and PCT assayed before and the first day after FFB were not significantly changed(P>0. 05). But the levels of CRP and PCT in the therapy group significantly decreased in the third day after FFB,and more than those in the control group. Furthermore,duration of invasive respiratory sup-port,and the stay of PICU were significantly shorter in the therapy group(P<0. 005). Conclusion FFB can play an important role in the collection of pathogenic microbes. It also achieves better results in the treatment of severe pneumonia for children in PICU. Therefore,it is worthwhile to be recommended as a safe and feasi-ble intervention in PICU.

Objective:To summary the mixed infection as well as clinical characteristics and analyze the risk factors for mixed infection of severe adenovirus pneumonia(SAP) in children.Methods:The clinical data of 114 children with SAP were retrospectively analyzed.Multivariate Logistic regression analysis was performed to assess the risk factors for mixed infection.Results:The incidence age was from 6 months to 2 years(62.5%). High fever(94.7%), cough(98.2%), dyspnea(86.8%) and lethargy(95.6%) were the main symptoms.Laboratory examination showed that children with SAP were prone to increased white blood cell count, C-reactive protein, procalcitonin, aspartate aminotransferase, alanine aminotransferase and CK-MB, as well as decreased proportion of CD3 + , CD4 + , CD8 + , CD4 + /CD8 + and NK cells.The main complications intrapulmonary organ were respiratory failure(80.7%). The main complications extrapulmonary organ were circulatory complications (55.3%). SAP was easily combined with other pathogenic infections.Streptococcus pneumoniae(22.9%)was the most common bacterial pathogen.Respiratory syncytial virus(10.0%)were the most common virus, in addition, mycoplasma pneumoniae(17.1%) was also common.Multivariable Logistic regression analysis showed that the decreasing ratio of CD4 + /CD8 + and NK cells, congenital heart disease and congenital airway dysplasia were the independent risk factors for mixed infection of SAP in children( P<0.05). Conclusion:The SAP patients could easily suffer from mixed infection and high fatality rate.Immune dysregulation is the important risk factors for mixed infection of SAP in children.So immunoregulatory treatment is very important.

Objective:To analyze the characteristics of child cases admitted to accidental injury and provide reliable basis for the prevention of accidental injury.Methods:The clinical data of children admitted to Hunan Children′s Hospital aged 0-18 due to accidental injuries from January 1, 2018 to December 31, 2021 were retrospectively analyzed. The type of accidental injury and characteristic factors such as prognosis, gender, age, time, and location of the child were analyzed.Results:A total of 9 049 children with accidental injury were admitted, accounting for 3.72%(9 049/33 697) of the total number of hospitalized children. The top three types of accidental injuries were falls/drop (3 695 cases), foreign bodies/suffocation (2 639 cases) and traffic accidents (1 165 cases), accounting for 82.87%(7 499/9 049). There were 8 760 cases (96.81%) of improvement and recovery, 178 cases (1.97%) of disability, and 111 cases (1.23%) of unhealed/dead. Among the accidental injuries, 5 833 cases (64.46%) were boys and 3 216 cases (35.54%) were girls, and the incidence ratio was 1.81∶1. There was significant difference between boys and girls in the composition ratio of the type of accidental injury such as falls/falls, foreign bodies/suffocation, poisoning, sharp object injury, drowning ( χ2 values were 3.90-20.56, all P<0.05). Among the accidental injuries, the children aged 1 to<3 years had higher accidental injuries than the other age groups (3 263 cases, accounting for 36.06%), and the composition ratio of accidental injuries in different age groups was different ( χ2 values were 12.98-573.97, all P<0.05). Among the accidental injuries, the accidental injuries occurred in the second quarter and the third quarter were higher than those in the other two quarters (4 892 cases, accounting for 54.06%), and the composition ratio of accidental injuries such as falls/falls, foreign bodies/suffocation, burn and scald, drowning occurred in different quarters was different ( χ2 values were 10.79-18.88, all P<0.05). In the case of accidental injuries, the family was the most likely place of accidental injury, with different types of accidental injuries occurring in different places ( χ2 values were 10.08-2 186.54, all P<0.05). Conclusions:Children′s unintentional injuries are most likely to occur in boys aged 1-<3 years, and fall/fall is the main injury type. Traffic accidents are the most important unintentional injury type leading to children′s unhealed/dead. Different injury types were related to child gender, age, quarter, and place of occurrence.Due to the differences in the occurrence mechanism and injury mode of accidental injuries in different countries and regions, and the majority of accidental injuries can be prevented, targeted preventive measures should be taken according to the characteristics of children′s accidental injuries in different regions, and a comprehensive prevention system for children′s accidental injuries should be constructed to ensure children′s safety.
