Objective To study the relationships between serum intedeukin-18(IL-18)and resistin for predicting intraamniotic infection.Method Serum levels of IL-18 and resistin were measured in 43 pregnant women with intraamniotic infection (infection group)and 40 normal pregnant women(control group).Results The level of IL-18 in infection group[(38.7±10.4)μg/L]was higher than that in control group [(23.5±5.6)μg/L],there was significant difference between two groups (P＜0.01).The level of resistin in infection group[(24.84±5.32)μg/L]was higher than that in control group[(17.3±5.15) μg/L],there was significant difference between two groups(P＜0.01).The levels of resistin and IL-18 were correlated in pregnant women with intraamniotic infection(r=0.61,P＜0.01).Conclusion Detecting the levels of IL-18 and resistin in pregnant women can identify intramnniotic infection.

Objective:To improve the diagnostic criteria of suspected cases through investigating the epidemiological and clinical manifestations of confirmed cases of novel coronavirus infection in children.Methods:We retrospectively analyzed the epidemiological and clinical manifestations of six children with novel coronavirus infection diagnosed in Chongqing Three Gorges Central Hospital from February 3, 2020 to February 15, 2020.Compared with the diagnostic criteria of suspected cases, we summarized the problems encountering in the application of this standard in clinic and try to put forward suggestions for improvement.Results:Among the six confirmed cases: five males and one female; three from Hubei Province and three from Wanzhou; six cases of clustered onset of the family.Visiting nature: six cases of suspected case, six cases from community or outpatient screening.Three fever cases with/without respiratory symptoms, one of which had diarrhea; all children′s blood routine and lymphocyte counts were within the normal range; chest CT imagings of No.1 and No.5 case showed typical novel coronavirus pneumonia signs, and the other three patients had abnormalities without the characteristics of novel coronavirus pneumonia, and one case was normal.Comparison results: Only No.1 case fully met the diagnostic criteria, and the remaining cases did not meet the diagnostic criteria for early suspected cases.Conclusion:In order to improve the accuracy and practicality of the diagnosis of suspected cases in children, it is recommended to refine and standardize the diagnostic criteria for some suspected cases.

Objective:To investigate the value of systemic inflammatory response syndrome (SIRS), pediatric sequential organ failure assessment (pSOFA) and pediatric critical illness score (PCIS) in predicting mortality of pediatric sepsis in pediatric intensive care units (PICU) from Southwest China.Methods:This was a prospective multicenter observational study. A total of 447 children with sepsis admitted to 12 PICU in Southwest China from April 2022 to March 2023 were enrolled. Based on the prognosis, the patients were divided into survival group and non-survival group. The physiological parameters of SIRS, pSOFA and PCIS were recorded and scored within 24 h after PICU admission. The general clinical data and some laboratory results were recorded. The area under the curve (AUC) of the receiver operating characteristic curve was used to compare the predictive value of SIRS, pSOFA and PCIS in mortality of pediatric sepsis.Results:Amongst 447 children with sepsis, 260 patients were male and 187 patients were female, aged 2.5 (0.8, 7.0) years, 405 patients were in the survival group and 42 patients were in the non-survival group. 418 patients (93.5%) met the criteria of SIRS, and 440 patients (98.4%) met the criteria of pSOFA≥2. There was no significant difference in the number of items meeting the SIRS criteria between the survival group and the non-survival group (3(2, 4) vs. 3(3, 4) points, Z=1.30, P=0.192). The pSOFA score of the non-survival group was significantly higher than that of the survival group (9(6, 12) vs. 4(3, 7) points, Z=6.56, P<0.001), and the PCIS score was significantly lower than that of the survival group (72(68, 81) vs. 82(76, 88) points, Z=5.90, P<0.001). The predictive value of pSOFA (AUC=0.82) and PCIS (AUC=0.78) for sepsis mortality was significantly higher than that of SIRS (AUC=0.56) ( Z=6.59, 4.23, both P<0.001). There was no significant difference between pSOFA and PCIS ( Z=1.35, P=0.176). Platelet count, procalcitonin, lactic acid, albumin, creatinine, total bilirubin, activated partial thromboplastin time, prothrombin time and international normalized ratio were all able to predict mortality of sepsis to a certain degree (AUC=0.64, 0.68, 0.80, 0.64, 0.68, 0.60, 0.77, 0.75, 0.76, all P<0.05). Conclusion:Compared with SIRS, both pSOFA and PCIS had better predictive value in the mortality of pediatric sepsis in PICU.

Objective: To improve the diagnostic criteria of suspected cases through investigating the epidemiological and clinical manifestations of confirmed cases of new-type coronavirus infection in children. Methods: We retrospective analyzed the epidemiological and clinical manifestations of 6 children with new coronavirus infection diagnosed in Chongqing Three Gorges Central Hospital from February 3, 2020 to February 15, 2020 . Compared with the diagnostic criteria of suspected cases,we summarized the problems encountered in the application of this standard in clinical work and try to put forward Suggestions for improvement. Results: Among the 6 children with confirmed cases: 5 males and 1 female; 3 from Hubei Province and 3 from Wanzhou ; 6 cases of clustered onset of the family; Visiting nature: 3 cases of suspected case income, 3 cases of community or outpatient screening . Three cases with fever and / or respiratory symptoms, one of which had symptoms of diarrhea; all children's blood routine and lymphocyte counts were within the normal range; chest CT imaging except for cases No. 1 and No. 5 were in line with typical new coronavirus pneumonia signs. In addition, the remaining 3 patients had abnormal imaging but did not have the characteristics of new coronavirus pneumonia, and 1 case was normal. Comparison results:Only case 1 of all cases fully met the diagnostic criteria, and the remaining cases did not meet the diagnostic criteria of early suspected cases. Conclusion In order to improve the accuracy and practicality of the diagnosis of suspected cases in children, it is recommended to refine and standardize the diagnostic criteria of some suspected cases.
