The survey on the hesitant status of rubella-containing vaccine (RCV) vaccination was conducted among 2 141 women of childbearing age in four provinces, Liaoning, Jiangsu, Zhejiang, and Anhui, from May 2017 to March 2018. Among the 2 141 study participants, a total of 38.21% (818) of women of childbearing age were aware of rubella and 21.25% (455) of women of childbearing age knew about RCV. Among the 455 women of childbearing age who were aware of RCV, 262 (57.58%) were willing to be vaccinated with RCV; 304 women of childbearing age (66.81%) tended to be vaccinated with RCV free of charge. Among the 193 women of childbearing age who did not want to be vaccinated or did not decide whether they preferred to be vaccinated with RCV, no one around them was vaccinated (89, 46.11%) and fear of vaccine safety (70, 36.27%) were the main reasons for hesitation to receive RCV.

Objective: To compare the clinical efficacy of anterior column reconstruction using single or double titanium mesh cage (TMC) after total en bloc spondylectomy (TES) of thoracic and lumbar spinal tumors. Methods: A retrospective cohort study was performed involving 39 patients with thoracic or lumbar spinal tumors. All patients underwent TES, followed by anterior reconstruction and screw-rod instrumentation via a posterior-only procedure. Twenty-two patients in group A were treated with a single TMC to reconstruct the anterior column, whereas 17 patients in group B were reconstructed with double TMCs. Results: The overall follow-up is 20.5 ± 4.6 months. There is no significant difference between the 2 groups regarding age, sex, body mass index, tumor location, operative time, and intraoperative blood loss. The time for TMC placement was significantly shortened in the double TMCs group (5.2 ± 1.3 minutes vs. 15.6 ± 3.3 minutes, p = 0.004). Additionally, postoperative neural complications were significantly reduced with double TMCs (5/22 vs. 0/17, p = 0.046). The kyphotic Cobb angle and mean intervertebral height were significantly corrected in both groups (p ≤ 0.001), without obvious loss of correction at the last follow-up in either group. The bone fusion rates for single TMC and double TMCs were 77.3% and 76.5%, respectively. Conclusion Using 2 smaller TMCs instead of a single large one eases the placement of TMC by shortening the time and avoiding nerve impingement. Anterior column reconstruction with double TMC is a clinically feasible, and safe alternative following TES for thoracic and lumbar tumors.

【Objective】 To investigate the value of three hemolysis tests and carboxyhemoglobin (COHb) level in the diagnosis of hemolytic disease of the fetus and newborn (HDFN). 【Methods】 From January 1, 2019 to December 31, 2022, the neonates hospitalized in the Department of Neonatology of Hebei Provincial Children's Hospital with suspected hemolytic disease who had serological testing were retrospectively enrolled in the study. They were distributed into HDFN group and non-HDFN group according to the final diagnosis. Their clinical and laboratory data were collected and analyzed, and the COHb level was detected by blood gas analyzer. 【Results】 A total of 378 neonates with HDFN and 217 neonates without HDFN were included in the study. Most of the neonates in HDFN group were full-term infants (348/378, 92.1%), with median gestational age of 39.1 (38.3, 40.0) weeks. Three hundred and fifty-four cases (354/378, 93.7%) were ABO-HDFN and the rest were Rh HDFN. There were significant differences in the level of serum total bilirubin, hemoglobin, COHb and reticulocyte percentage at admission between the two groups(P<0.05). The positive rate of three hemolysis tests in HDFN group decreased with the increase of the days after birth. The highest positive rate (more than 80%) was observed within 2 days after birth. Correlation analysis showed a negative relationship between the COHb level and the age (rs = -0.434, P<0.001) . Among the three hemolysis tests in HDFN group, the positive rate of antibody release test was the highest (69.0%), followed by the free antibody test (55.6%) and the direct antiglobulin test (DAT) (36.0%). Receiver operating characteristic (ROC) curve analysis showed that the optimal cut-off value of COHb was 1.15%.The sensitivity of COHb ≥ 1.15% was 51.8%, higher than single DAT (36.0%) . The diagnosis effectiveness of three hemolysis tests couldn't be improved when combined with COHb detection(Z = -0.727, P>0.05) . 【Conclusion】 The three hemolysis tests are important in the diagnosis of HDFN, among which the antibody release test has the highest sensitivity. COHb has certain value for the diagnosis of HDFN, but joint testing cannot improve the diagnosis effectiveness of three hemolysis tests. Hemolysis tests and/or COHb detection should be conducted for neonates at risk of hemolysis as early as possible after birth.

Objective:To study the clinical features of neonatal hyperthyroidism.Methods:From September 2013 to September 2020, clinical data of neonates with hyperthyroidism admitted to the neonatal intense care unit of our hospital were retrospectively collected and analyzed.Results:A total of 7 neonates were included. The average gestation age was (35.8±2.3) weeks with 5 cases had GA<37 weeks. The median age of diagnostic was 16 d (7~18 d). The common clinical manifestations included tachycardia, irritability, low-grade fever, hyperhidrosis, bulimia, poor weight gain, diarrhea and jaundice. The levels of serum free triiodothyronine (FT 3) and thyroxine (FT 4) were elevated in all 7 cases and thyroid stimulating hormone (TSH) were decreased. The Doppler ultrasound of thyroid gland in two neonates revealed enlarged thyroid gland with abundant blood flow. All 7 mothers had hyperthyroidism with 4 mothers provided the history of hyperthyroidism and the other 3 were also confirmed after their infants were diagnosed. All 7 infants were treated with anti-thyroid drugs (ATD) and 2 were additionally given β-blockers to control heart rate. The median ATD duration was 40 d (7~58 d). 2 cases (both preterm infants) had slight decrease in FT 4 during medication. FT 4 of all 7 cases returned to normal before TSH. Conclusions:Neonatal hyperthyroidism has various and nonspecific clinical manifestations. Early diagnosis and timely treatment are important to prevent short-term and long-term adverse outcomes. Whether their mothers provide definite history of thyroid disorder or not, the thyroid function of the suspected neonates should be carefully monitored.

Objective:To test the HIV virus nucleic acid using immunoblot method (Western blotting, WB) and to follow-up with the negative and indeterminate samples in the Dujiangyan area, compare the WB and nucleic acid results before and after followed-up, and try to reduce the WB band′s false-negatives and false-positives.Methods:The 286 suspected HIV infection samples in the Dujiangyan region from January to October 2021 were confirmed by WB, the HIV virus load were tested for the samples that were WB negative and WB indeterminate, those patients were followed-up with epidemiological history and viral load results, and the results before and after tracking were compared.Results:In the 286 samples of suspected HIV infection included in this study, we reported 213 (74.48%) WB positive, 37 WB negative (12.94%), and 36 WB indeterminate (12.58%); 10 of 37 WB negative samples were followed-up; 18 of 36 WB indeterminate samples were followed-up. Among the followed-up WB negative and indeterminate samples, 17 of them had virus nucleic acid detection prior to the follow-up, and all of them turned positive after following-up. The others with no previous virus nucleic acid detection were confirmed to be negative.Conclusions:Among the followed-up samples, 2 samples were false-negative in WB negative results, and 3 were false-positive in WB indeterminate results. The viral nucleic acid must be tested and followed-up in WB negative and indeterminate samples.
