RESUMO

OBJECTIVE: To investigate the incidence of severe neonatal hyperbilirubinemia and the management on the treatment and follow-up of this disease in Jiangsu Province, China. METHODS: The neonates with severe hyperbilirubinemia who were admitted to 13 hospitals in Jiangsu Province from January to December, 2018, were enrolled as subjects. A retrospective analysis was performed on their mediacal data and follow-up data. RESULTS: In 2018, 740 neonates with severe hyperbilirubinemia were reported from the 13 hospitals in Jiangsu Province, accounting for 2.70% (740/27 386) of the total number of neonates admitted to the department of neonatology. Among these neonates, 620 (83.8%) had severe hyperbilirubinemia, 106 (14.3%) had extremely severe hyperbilirubinemia, and 14 (1.9%) had hazardous hyperbilirubinemia. Four neonates (0.5%) were diagnosed with acute bilirubin encephalopathy. A total of 484 neonates (65.4%) were readmitted due to severe hyperbilirubinemia after discharge from the delivery institution, with a median age of 7 days, among whom 214 (44.2%) were followed up for jaundice at the outpatient service before readmission, with a median age of 6 days at the first time of outpatient examination. During hospitalization, 211 neonates (28.5%) underwent cranial MRI examinations, among whom 85 (40.3%) had high T1WI signal in the bilateral basal ganglia and the globus pallidus; 238 neonates (32.2%) underwent brainstem auditory evoked potential examinations, among whom 14 (5.9%) passed only at one side and 7 (2.9%) failed at both sides. The 17 neonates with acute bilirubin encephalopathy or hazardous hyperbilirubinemia were followed up. Except one neonate was lost to follow-up, and there were no abnormal neurological symptoms in the other neonates. CONCLUSIONS: Neonates with severe hyperbilirubinemia account for a relatively high proportion of the total number of neonates in the department of neonatology. Jaundice monitoring and management after discharge from delivery institutions need to be strengthened. For neonates with severe hyperbilirubinemia, relevant examinations should be carried out more comprehensively during hospitalization and these neonates should be followed up comprehensively and systematically after discharge.

RESUMO

Polygala tenuifolia Willd. is an important protected species used in traditional Chinese medicine. In the present study, amplified fragment length polymorphism (AFLP) markers were employed to characterize the genetic diversity in wild and cultivated P. tenuifolia populations. Twelve primer combinations of AFLP produced 310 unambiguous and repetitious bands. Among these bands, 261 (84.2%) were polymorphic. The genetic diversity was high at the species level: percentage of polymorphic loci (PPL)=84.2%, Nei's gene diversity (h)=0.3296 and Shannon's information index (I)=0.4822. Between the two populations, the genetic differentiation of 0.1250 was low and the gene flow was relatively high, at 3.4989. The wild population (PPL=81.9%, h=0.3154, I=0.4635) showed a higher genetic diversity level than the cultivated population (PPL=63.9%, h=0.2507, I=0.3688). The results suggest that the major factors threatening the persistence of P. tenuifolia resources are ecological and human factors rather than genetic. These results will assist with the design of conservation and management programs, such as in natural habitat conservation, setting the excavation time interval for resource regeneration and the substitution of cultivated for wild plants.

RESUMO

OBJECTIVE: To analyze the clinical features of 6 children with Duchenne muscular dystrophy (DMD) and review related literature, and to provide a basis for early diagnosis and effective treatment of this disease. METHODS: A retrospective analysis was performed on the clinical data of 6 children with DMD who were admitted to the First Affiliated Hospital of Nanjing Medical University from January 2010 to October 2015. RESULTS: All the 6 cases were boys without a family history of DMD, and the age of diagnosis of DMD was 1.2-11.5 years. All patients had insidious onset and increases in alanine aminotransferase, aspartate aminotransferase, lactate dehydrogenase, α-hydroxybutyrate dehydrogenase, creatine kinase (CK), and creatine kinase-MB, particularly CK, which was 3.3-107.2 times the normal level. Their gene detection results all showed DMD gene mutation. The gene detection results of two children's mothers showed that they carried the same mutant gene. The muscle biopsy in one case showed that the pathological changes confirmed the diagnosis of DMD. The level of CK in one case declined by 77.0% 5 days after umbilical cord blood mesenchymal stem cell transplantation. CONCLUSIONS: For boys with abnormal serum enzyme levels and motor function, DMD should be highly suspected. It should be confirmed by CK and DMD gene detection as soon as possible. And the progression of the disease could be delayed by early intervention for protecting the remaining normal muscle fibers.
