Objective To observe the effect of Rood therapy intervened very early on development of premature infants. Methods 148 hospital-born infants gestated 32 weeks with high risk of brain injury were divided into intervention group (n=74) and control group (n=74).All the cases accepted routine treatment and nursing, and the intervention group accepted Rood therapy in addition. They were followed up to 28th day, assessed with Neonatal Behavioral Neurological Assessment (NBNA). Results The NBNA score was more in the intervention group than in the control group (P<0.05) in all the sub-scores except primitive reflexes. Conclusion Rood therapy is useful to improve the neural development in premature infants in 32 to 36 weeks.

Objective: To understand the similarities and differences in different dosage forms of tuberculin test for college students having close contact with tuberculosis in Nanning colleges and universities in order to provide reference for the prevention and control of tuberculosis. Methods: A total of 7 771 students were screened for symptoms and tuberculin skin test(TST)、X radiographs from 2018 to 2019 in Nanning.The used doses of Purified Protein Derivative of Tuberculin (TB-PPD) in 2018 and 2019 were 2 IU and 5 IU respectively. Results: A total of 916 positive cases were detected in 2 years, with the total positive rate of 11.79%. Total strong positive number was 184 and the strong positive rate was 2.37%. The number of tuberculosis patients was 17. Positive rate of the students from grade one to grade four was 13.88%, 8.57%, 10.59%, 10.29%, respectively. The difference was statistically significant(χ 2=46.30，P＜0.01). The positive rates of male and female in the past two years were 13.24%(500/3 777) and 10.42%(416/3 994), respectively (χ 2=17.84, P<0.01)，and there was no significant difference in the diagnosis of pulmonary tuberculosis among TST positive patients (χ 2=0.29,P=0.59). The positive and strong positive rates of 2 IU dose and 5 IU dose were 7.57%, 15.04%, respectively, the difference in dosage forms were statistically significant (χ 2=114.41,P<0.01). The tuberculosis case detection rate (CDR) of moderate & above positive subjects of 2 IU and 5 IU dose was 6.92% and 2.07%, respectively, the difference was statistically significant(χ 2=6.60，P=0.02). Conclusion More positive tuberculosis cases (including moderate & strong positive) can be detected by using 5 IU dose, though it is may not have advantage over discovering tuberculosis patients comparing to 2 IU dose. However, it is more critical to minimize the following cases and control the outbreak in university.

Lymphoma is a common hematological malignant tumor which poses a great threat to human health. Chemotherapy, molecular targeted therapy, and hematopoietic stem cell transplantation constitute the main treatment methods for lymphoma, however, there are still some patients with lymphoma suffer from drug resistance, relapse and refractory. Ferroptosis is a newly discovered mode of programmed cell death, which is related to iron-dependent lipid peroxidation damage. Targeting ferroptosis provides a novel landscape for inhibiting the growth of lymphoma. We reviewed the mechanism of ferroptosis from the initial signals, intermediate events, effect stages, defense mechanisms and summarized the research progress of ferroptosis in lymphoma, providing novel therapeutic targets in the treatment of lymphoma.

Objective    To explore the feasibility of ultrasound diagnosis of diaphragmatic paralysis in patients with ventilation after congenital heart disease surgery. Methods    There were 542 patients with congenital heart disease after surgery, difficult to be weaned off the ventilator or suspected diaphragmatic paralysis of the patients, respectively, in the ventilator continous positive pressure breathing (CPAP) mode and completely independent breathing state, whose ultrasound examination of diaphragm function was conducted to determine the presence of diaphragmatic paralysis in our hospital between January 1, 2013 and April 30, 2016. There were 327 males and 215 females at age of 14±32 months. The results of ultrasound diagnosis between ventilator CPAP mode and completely spontaneous breathing mode were compared. Results    Five hundred and forty-two patients underwent ultrasound diaphragmatic examination. The results of bedside ultrasound were completely diagnosed: in completely spontaneous breathing, 82 patients who were diagnosed as diaphragmatic paralysis, including 39 on the right, 25 on the left, 18 on both sides; in CPAP mode, 82 patients who were diagnosed as diaphragmatic paralysis, 38 on the right, left 25, bilateral 19. Using ultrasound in CPAP mode to diagnose diaphragmatic paralysis after congenital heart disease surgery, compared with the completely spontaneous breathing state, the sensitivity was 100.0% and the specificity was 99.9%. Conclusion    It is accurate and feasible to diagnose the presence of diaphragmatic paralysis in patients with ventilation after congenital heart disease surgery.
