Objective:To investigate the perinatal prognosis and its impact factors for premature infants with twin-twin transfusion syndrome (TTTS) who were born at ≤34 weeks of gestation.Methods:A retrospective study was conducted on 68 pregnancies of TTTS with gestational age ≤34 weeks at delivery, among them 106 preterm infants (TTTS group) were admitted to the neonatal intensive care unit of the First Affiliated Hospital, Sun Yat-sen University from January 2003 to February 2019. During the same period, another 178 twins without TTTS, congenital malformation, and intrauterine intervention who matched the TTTS group in maternal age (differences within two years) and gestational age (differences within one week) were assigned as non-TTTS group. Perinatal prognosis of TTTS infants born at ≤34 weeks was analyzed by comparing the differences in postnatal early complications and perinatal outcomes (survival time morn than 28 days or not) between the TTTS and non-TTTS groups, recipient and donor twins, mild and severe TTTS infants, and among TTTS infants with different intrauterine interventions. The risk factors for perinatal survival in TTTS infants with gestational age ≤34 weeks were analyzed. Two independent samples t-test, one-way analysis of variance, rank-sum test, Chi-square test, and ordered logistic regression were used for statistical analysis. Results:(1) Among the 68 pregnancies, the overall perinatal survival rate of the neonates was 72.1% (98/136), the double-twin survival rate was 48.5% (33/68), and the rate of at least one survivor was 95.6% (65/68). (2) In the TTTS group, 62 were recipients and 44 were donors. Stage Ⅰ-Ⅱ TTTS was found in 41 cases (mild TTTS group) and stage Ⅲ-Ⅴ in 65 cases (severe TTTS group). (3) The rate of severe brain injury was higher in the severe-TTTS group than those in the mild-TTTS group [9.2% (6/65) vs. 0.0% (0/41), χ 2=4.01, P=0.045]. (4) Gestational age ≤28 weeks ( OR=101.90, 95% CI: 5.07-2 048.37), stage Ⅳ ( OR=14.04, 95% CI: 1.56-126.32) and stage Ⅴ TTTS ( OR=51.09, 95% CI: 3.58-728.81) were independent risk factors for death within 28 days (all P<0.05). (5) Compared with the non-TTTS group, the TTTS group had higher rates of neonatal anemia [51.9% (55/106) vs. 33.1% (59/178), χ 2=9.71], polycythemia [5.7% (6/106) vs. 0.6% (1/178), χ 2=7.18], neonatal persistent pulmonary hypertension [3.8% (4/106) vs. 0.0% (0/178), χ 2=6.81], sepsis [15.1% (16/106) vs. 7.3% (13/178), χ 2=4.40], state Ⅲ or higher retinopathy of prematurity [3.8% (4/106) vs. 0.0% (0/178), χ 2=6.81], congenital cardiac structural abnormality [19.8% (21/106) vs. 0.6% (1/178), χ 2=33.45], heart failure [8.5% (9/106) vs. 0.6% (1/178), χ 2=12.29], and renal insufficiency [14.2% (15/106) vs. 1.1% (2/178), χ 2=20.04] (all P<0.05). Conclusions:Compared with the twin premature infants without TTTS, those with TTTS and ≤34 gestational age were more likely to have cardiac, cerebral, and renal complications. The more severe the TTTS, the higher the incidence of severe brain injury. TTTS preterm infants with gestational age ≤28 weeks and stage Ⅳ or above have high risk of death.

Objective:To investigate the changes of mortality，causes of death，and cause-specific mortality rate（CMR）of hospitalized neonates in NICU of the First Affiliated Hospital of Sun Yat-sen University.Method:A retrospective study was performed to compare the mortality，cause of death，and CMR of hospitalized neonates in period Ⅰ（2005-2009），period Ⅱ（2010-2014）and period Ⅲ（2015-2020）.Result:The overall mortality of hospitalized neonates in NICU of our hospital was 0.51%（104/20 493）through 2005 to 2020. The mortality in period Ⅰ，Ⅱ and Ⅲ were 0.61%（48/7 855），0.43%（27/6 209），and 0.45%（29/6 429），respectively. Compared with period Ⅰ，the mortality of preterm infants decreased significantly in period Ⅱ（3.14% vs 1.24%， χ2=14.076， P<0.01）and in period Ⅲ（3.14% vs 0.90%， χ2=25.157， P<0.01）. Eighty-five（81.7%）neonates were premature，and ninety-one（89.2%）neonates had definite abnormal perinatal factors. The CMR of hospitalized neonates related to pulmonary hemorrhage，congenital anomalies，and NRDS were 1.22‰（25/20 493），0.93‰（19/20 493），and 0.59‰（12/20 493），respectively. The CMR of other causes were sepsis 0.44‰（9/20 493），extremely premature 0.34‰（7/20 493），and perinatal asphyxia 0.24‰（5/20 493），respectively. Compared with period Ⅰ，specific mortality of NRDS in period Ⅱ（1.27‰ vs 0.16‰， χ2=5.487， P=0.016）and period Ⅲ（1.27‰ vs 0.16‰， χ2=5.738， P=0.014）significantly decreased. The leading causes of neonatal death in period Ⅰ，period Ⅱ，and period Ⅲ were NRDS，pulmonary hemorrhage，and congenital anomalies，respectively.And 71.2%（74/104）of neonatal deaths occurred within 7 days after birth. Conclusion:The mortality of preterm infants and specific mortality of NRDS in NICU have significantly decreased over the past 16 years.Congenital anomalies and infections remain important causes of death，and further efforts are needed to improve perinatal care.

Objective To explore the application of painless diagnosis and treatment technology in children's peripherally inserted central catheter(PICC)guided by ultrasound.Methods Totally 82 children who planned to undergo PICC in the hospital from January 2021 to January 2023 were selected and randomly divided into a control group and an observation group using a random number table method,with 41 cases in each group;The control group underwent conventional ultrasound guided PICC catheterization,while the observation group underwent painless diagnostic and therapeutic techniques using ultrasound guided PICC catheterization;Compare the success rate of catheterization,completion time of catheterization,degree of pain in the child pain[children's pain behavior scale(FLACC)],tolerance[Houpt behavior scale(HBS)],compliance[Frankl scale(FCS)],and family satisfaction between the two groups.Results The success rate of catheterization in the observation group was higher than that in the control group,and the catheterization time was shorter than that in the control group,with a statistically significant difference(P<0.05).The FLACC score of the observation group was lower than that of the control group,while the HBS score and FCS score were higher than those of the control group,with a statistically significant difference(P<0.05);The total satisfaction of family members in the observation group was higher than that in the control group,and the difference was statistically significant(P<0.05).Conclusion The use of painless diagnosis and treatment technology in ultrasound-guided PICC catheterization in children can improve the success rate of catheterization,shorten the catheterization time,reduce the degree of pain in children,enhance tolerance and compliance,and improve family satisfaction.

Objective To search for new biomarkers to predict prognosis in colorectal cancer (CRC) patients.Methods A prognostic model was developed for colorectal cancer with immune-related genes from the cancer ge-nome atlas (TCGA) database using one-way Cox regression analysis and least absolute shrinkage and selection op-erator (LASSO) regression analysis.Moreover, the immune infiltration characteristics of patients in high and low risk groups was compared by sstimation of stromal and immune cells in malignant tumor tissues using expression da-ta (ESTIMATE) and cell-type identification by estimating relative subsets of RNA transcripts (CIBERSORT) .In addition, the expression levels of immune checkpoints were analyzed in patients from different risk groups.The sen-sitivity of patients in the two risk groups to chemotherapeutic agents was also compared based on genomics of drug sensitivity in cancer (GDSC).Results It was found that the prognostic model constructed based on immune genes could better predict the overall survival (OS) of CRC patients,and the results showed area under curve (AUC) values of 0.764 (95％ CI:0.751-0.793), 0.773 (95％ CI:0.761 -0.779), and 0.760 (95％ CI:0.742 -0.774) for 1-, 3-, and 5-year OS, respectively.Patients in the low-risk group had higher expression levels of im-mune checkpoints and more abundant immune cells such as T cells (P<0.001) , dendritic cells (P<0.001) , macrophages (P<0.001) , neutrophils (P<0.001) .Patients in the high-risk group might be more sensitive to some chemotherapeutic agents such as axitinib, imatinib, methotrexate, pazopanib, rapamycin, sunitinib and tasig-arnib.Conclusion A prognostic model based on 19 immune genes was effective in predicting the prognosis of CRC patients.The number and activity of immune cells in the immune microenvironment in different patients may be an important factor influencing their response to immunocheck inhibitors and chemotherapeutic agents.
