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 explore the genetic basis for a child with neonatal severe hyperparathyroidism. METHODS: Genomic DNA was extracted from peripheral blood samples from the patient and her parents. Whole exome sequencing was carried out to screen potential mutations. Suspected mutation was verified by Sanger sequencing. RESULTS: The proband was found to carry compound heterozygous variants c.179G>A (p.Cys60Tyr) and c.1525G>A (p.Gly509Arg) of the CaSR gene. The c.179G>A variant was derived from her mother and was unreported previously. The c.1525G>A variant was derived from her father and known to be pathogenic. CONCLUSION The compound heterozygous variants of c.179G>A and c.1525G>A of the CaSR gene probably underlie the disease in the patient. The results of genetic testing has enabled diagnosis and genetic counseling for her family.

Behavioral experience included mainly self-psychological adjustment, positive and optimistic face, firm belief, cognitive disadvantage and active avoidance. Cognitive experience included family and social support and medical help.Conclusions:Medical staff need to strengthen the guidance of the negative psychology of newly diagnosed patients and increase their positive psychological experience. It is necessary to encourage patients to adopt suitable health and psychological adjustment methods and face the disease optimistically.

Objective To explore the safety and long-term results of preoperative imatinib mesylate administration (IM) in patients with locally advanced gastrointestinal stromal tumors (GIST).Methods From Sep 2009 to Nov 2016,locally advanced GIST patients treated in Fujian Medical University Cancer Hospital were analysed retrospectively.Result 34 patients were included.Preoperative median IM treatment was 27 weeks(range 12-71 weeks).65％ patients had a partial response to IM,35％ showed stable disease.All patients underwent surgical R0 resection.The complication rate was 9％ and no death occurred within 30 days post operation.The median follow-up time was 62.2 months (range of 13-89 months).20 patients continued to take imatinib orally,14 patients did not.The 3 year survival rate of patients undergoing surgery was 67％.Univariate analysis showed that tumor location,preoperative imatinib effect,pathology,targeted therapy after surgery were factors affecting prognosis.Multivariate analysis show that the independent risk factors affecting prognosis were tumor location,pathology,targeted therapy after surgery.Conclusion In locally advanced GISTs,preoperative IM is useful and safe that can effectively decrease tumor size,facilitating resection.

Objective To report clinical characteristics and genetic results of two sisters suffered from congenital adrenal cortex hyperplasia (17-α-hydroxylase deficiency), and relevant literatures were reviewed. Methods Clinical manifestation and laboratory examination data of two sister cases of 17-α-hydroxylase deficiency enrolled in Capital Institute of Pediatrics in March 2016 were analyzed. Sanger sequencing and MLPA for CYP17A1 genes were performed and the parents' genes were also verified. Results The two patients were four years and 10 years old, both suffered from hypokalemia after infections, and hypergonadotrophin gonad hypofunction. One case was with slightly high blood pressure. Laboratory test results showed potassium fluctuation tendency in 1.9~4.0 mmol/L, 17-OHP and DHEA was decreased. Enhanced CT showed different degree of adrenal gland enlargement. Chromosome examination of the older sister is 46, XY. Both sisters demonstrated heterozygous mutation of CYP17A1 gene. The molecular genetic analysis suggested a c.985_987delTACinsAA from father and a deletion spanning exons 1-7 of the CYP17A1 gene from mother. Conclusion 17-α-hydroxylase enzyme deficiency can be diagnosed before adolescence. Clinical hypokalemia with unknown reason and high blood pressure may indicate the disease. The diagnosis can be confirmed with gene sequencing of CYP17A1.

Objective A 10-years-old girl with Schimke immuno-osseous dysplasia ( SIOD ) was reported and a literature review presented to provide clinical and genetic information of this rare disease. Methods Retrospective analysis of a case of SIOD in Capital Institute of Pediatrics was reported. The patient and her parents' DNA were extracted from blood for detecting SMARCALl gene mutation. Literatures of the disease were reviewed. Results The patient was a ten-years-old girl who admitted because of slow growth in height for 3 years. Herstaturewas123cm(T(p.Q149X)andc.1933C>T(p.R645C)compound heterozygous mutation. A novel nonsense c.445C>T(p. Q149X)was found. One reported missense mutations c. 1933C>T(p. R645C) was detected. We reviewed literatures and found that there were 4 confirmed cases in China including this one. All the 4 cases had the characteristic of short stature, special facial features, osseous dysplasia, pigmentations in body, and proteinuria. However the severity of the disease and genetic changes are not the same. Conclusion When a patient was admitted because of short stature, diagnosis of SIOD should be suspected if he or she also had special facial feature, osseous dysplasia, café-au-lait spots, and proteinuria. Gene test is a tool to help us to make a definite diagnosis of SIOD.

Objective: To investigate the clinical features and genetic characteristics of patients with ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1) gene variants. Method: The clinical data of a patient with ENPP1 homozygous variants from Capital Institute of Pediatrics was collected, the related literature was searched from China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform, National Center from Biotechnology Information and PubMed by using search term "ENPP1" , "hypophosphatemic rickets" . The literature retrieval was confined from 1980 to February 2017. The clinical manifestations, bone metabolism examinations, X-RAY and genotypes were reviewed. Result: Our patient was an 11 years old girl, with 7 years history of lower limb malformation. She showed significant valgus deformity of the knee (genu valgum). Metabolic examination revealed reduced level of plasma phosphate (0.86 mmol/L), a normal level of plasma calcium (2.30 mmol/L) and an elevated alkaline phosphatase level of 688 IU/L. The calcium-phosphorus product was 25.9. A homozygous nonsense variants of ENPP1 gene, c.783C>G (p.Tyr261X) in exon 7 was identified in the patient. Both parents were heterozygous carriers. Literature review identified 3 Chinese patients from one publication and 17 cases from twenty one publications around the world. None of the patients was found PHEX variants which is the most common variants among hypophosphatemic rickets patients. The disease onset age was 11 months to 10 years. Eight patients had short stature, five patients had the history of generalized arterial calcification of infancy. Four suffered from deafness, three showed localized calcifications of arteries, three patients manifested pseudoxanthoma elasticum and two suffered from ossification of posterior longitudinal ligament. Nine missense variants, six splicing variants and 4 nonsense variants were reported among these twenty patients. c.783C>G was found in two Chinese patients. Conclusion ENPP1 gene mutation was a cause of patient with hypophosphatemic rickets. Comorbid features included generalized arterial calcification of infancy, early onset hearing loss, pseudoxanthoma and ossification of posterior longitudinal ligament. ENPP1 gene testing should be performed on hypophosphatemic rickets patients without PHEX gene variants. Long-term follow up is recommended. The most common types of ENPP1 gene variants were nonsense/splicing variants. The gene c.783C>G was the most common variants in Chinese patients.
