Objectives To detect the cord blood vitamin D level in neonates and to determine the association between the cord blood vitamin D level and neonatal outcomes. Methods A total of 223 eligible mother-and-singleton-offspring pairs were recruited. The information of mothers' pregnancy was collected by questionnaires. The weight, length, and head circumference of neonates were measured. The levels of 25(OH)D in cord blood of neonates and in blood of late pregnancy mothers were determined by chemiluminescence immunoassay. Results The median concentration of 25(OH)D in cord blood was 20.7 nmol/L, and 82.1% of neonate had vitamin D deficiency, and 12.1% had severe vitamin D deficiency (<10 nmol/L). The concentration of 25(OH)D in cord blood was consistent with that in blood of late pregnancy mother. The distribution of concentration of 25(OH)D in cord blood was significantly different in neonates in different seasons of birth (P<0.05). There were more cases <10 nmol/L in winter and spring. The concentration of 25(OH)D in cord blood had no significant associations with the incidences of low birth weight (LBW) and small for gestational age (SGA) (P>0.05). After the variables of sex, gestational age and birth season are controlled, the birth weight and head circumference were significantly different in neonates with different concentrations of 25(OH)D in cord blood (P<0.05). Conclusions The concentration of 25(OH)D in cord blood in term neonates was generally lower. The vitamin D status in neonates was consistet with that in their late pregnancy mothers. Cord blood 25(OH) D levels were associated with neonates' birth weight and head circumference, but it should be confirmed by larger sample size in the future.

Objective To investigate the effects of two different oxygen therapies (oxygen time<4 h/d, oxygen flow>6 L/minversus oxygen time>4 h/d, oxygen flow<6 L/min) on conservative treatment of spontaneous pneumothorax by meta-analysis. Methods The following electronic databases as PubMed, The Cochrane Library, Web of Science, Chinese Biomedical Literature Database, WanFang Database and China National Knowledge Database were retrieved on computer for randomized controlled trials (RCTs) of comparing two different oxygen therapies (oxygen time<4 h/d, oxygen flow>6 L/minversus oxygen time>4 h/d, oxygen flow<6 L/min) on conservative treatment of spontaneous pneumothorax. The retrieval time was from inception of each database to December 2017. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assessed the methodological quality of the included studies. Then data were analyzed by RevMan 5.3 software. Results A total of 4 RCTs involving 226 patients were included. The meta-analysis showed that compared with lower oxygen flow (oxygen time>4 h/d, oxygen flow<6 L/min), the higher oxygen flow (oxygen time<4 h/d, oxygen flow>6 L/min) could obviously decrease the degree of pulmonary compression after oxygen therapy for 5 days (MD=–2.81, 95%CI –4.18 to –1.44, P<0.05), shorten duration of hospital stay (MD=–3.26, 95%CI –6.05 to –0.47, P<0.05) and duration of recruitment maneuvers (MD=–2.78, 95%CI –5.27 to –0.28, P<0.05), but there was no significant difference in oxygen partial pressure after oxygen therapy for 5 days (MD=10.68, 95%CI –7.03 to 28.39, P=0.24). Conclusion The higher oxygen flow (oxygen time<4 h/d, oxygen flow>6 L/min) can obviously decrease the degree of pulmonary compression after oxygen therapy for 5 days, shorten duration of hospital stay and duration of recruitment maneuvers, but the results are influenced by the number and quality of RCT.

Objective To investigate the rebleeding rate after endoscopic selective variceal devascularization (ESVD) and the predictive factors for rebleeding in patients with hepatitis B cirrhosis and esophageal variceal bleeding (EVB). Methods The patients with hepatitis B cirrhosis and EVB who attended Beijing Ditan Hospital, Capital Medical University, from October 2010 to December 2019 and underwent ESVD for the first time were enrolled, and a total of 442 patients were screened out based on inclusion and exclusion criteria. Routine clinical indices, laboratory markers, imaging findings, and endoscopic findings were compared between patients, and the patients were followed up to observe rebleeding. The t -test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test was used for comparison of categorical data between two groups. The Kaplan-Meier method was used to describe rebleeding and survival status, and a Cox regression analysis was used to determine the independent risk factors for variceal rebleeding. Results The 1-, 2-, 3-, 4-, and 5-year cumulative rebleeding rates after first ESVD treatment were 25.11%, 33.94%, 39.82%, 42.08%, and 45.02%, respectively. The univariate analysis showed that age, systolic pressure, duration of antiviral therapy ≥1 year, ascites, white blood cell count, neutrophil, and direct bilirubin were associated with rebleeding (all P < 0.05), and the multivariate analysis showed that duration of antiviral therapy ≥1 year (hazard ratio [ HR ]=0.504, 95% confidence interval [ CI ]: 0.357-0.711, P < 0.001) and ascites ( HR =1.424, 95% CI : 1.184-1.714, P < 0.001) were independent influencing factors for variceal rebleeding. Conclusion ESVD has a low rebleeding rate in the treatment of hepatitis B cirrhosis with EVB, and presence of ascites and a short duration of antiviral therapy are independent risk factors for rebleeding after treatment.
