OBJECTIVEUsing infant and child feeding index (ICFI) to evaluate the relationship between infant feeding and physical development indicators in rural areas of Lhasa.

METHODSIn July and August 2010 in the rural areas of Lhasa, the multi-stage cluster random sampling method was adopted to select 540 Tibetan children who were between 6 to 35 months of age. There were 70, 79 and 391 cases in 6 to 8, 9 to 11 and 12 to 35-month-old group respectively. The basic status of infants, information about breastfeeding and complementary feeding were collected by using designed questionnaires. Their height and weight were measured to calculate the children's weight for age Z-score (WAZ), height for age Z-score (HAZ) and weight for height Z-score (WHZ) and assess feeding index score (out of 17 scores) and analyze the relationship between feeding index and HAZ, WAZ and WHZ.

RESULTSThe mean ICFI score of 540 cases was 8.90 ± 2.82.It was 6.84 ± 3.16, 8.16 ± 2.78 and 9.41 ± 2.55 for 6 to 8, 9 to 11 and 12 to 35-month-old infants respectively. There was significant difference between the different month group (F = 30.99, P < 0.05).For the three month groups, the scores of WAZ were 0.10 ± 1.18, -0.09 ± 1.20 and -0.38 ± 0.96; HAZ were -0.60 ± 1.68, -1.02 ± 1.72 and -1.30 ± 1.30; WHZ were 0.62 ± 1.23, 0.69 ± 0.96 and 0.43 ± 0.95 respectively. The ICFI scores of 9 to 11, 12 to 35 and 6 to 35-month-old infants were positively correlated with HAZ (correlation coefficients were 0.25,0.12 and 0.09 respectively, all P values <0.05). There was no correlation with WAZ (correlation coefficients were 0.15,0.08 and 0.03 respectively, all P values >0.05) and WHZ (correlation coefficients were -0.08, -0.02, and -0.07 respectively, all P values >0.05). There were no correlation between ICFI score with HAZ, WAZ and WHZ for 6 to 8 month-old infants (correlation coefficient were 0.06,0.16 and -0.07 respectively, all P values >0.05).

CONCLUSIONTo some extent, the feeding index can effectively reflect the growth status of these infants and can serve as a comprehensive assessment of feeding situations among Tibetan children in rural areas of Lhasa.

Objectives:To systemically review the safety and efficacy of bioresorbable vascular scaffold (BVS) versus everolimus eluting stent (EES) for percutaneous coronary intervention (PCI). Methods:The database searched includes PubMed, Medline, MEDILINE, EMBASE, Cochrane library, CNKI and Wanfang. Database retrieval time was between database establishment time to October 2017. During the same time, authors accessed the conference summary and related websites to collect published randomized controlled trials of published data. To evaluate the quality of the literature according to the modified Jadad scale and extracted the data. Meta-analysis was performed using Review Manager 5.3 software. Results:Nine trials were included; 6 721 patients were randomized to receive BVS (n=3 670) or EES (n=3 051). Time of follow-up was ranged from 6 to 36 months. Compared with metallic EES, risk of target lesion failure (RR=1.31, 95%CI:1.08-1.58; P=0.005) and in-stent thrombosis (RR=2.89, 95%CI:1.85-4.53; P＜0.0001), ischemia-driven target lesion revascularization (RR=1.44,95%CI:1.12-1.86, P=0.005)、target-vessel myocardial infarction (RR=1.74, 95%CI:1.33-2.27, P＜0.0001) and all myocardial infarction (RR=1.49, 95%CI:1.16-1.91, P=0.002) were all significantly higher in BVS group than in EES group. There were no significant differences in all-cause death (RR=0.87, 95 % CI:0.57-1.33, P=0.520), cardiovascular mortality (RR=0.78, 95%CI:0.54-1.11, P=0.160) and composite endpoints (RR=1.10, 95%CI:0.95-1.27, P=0.210) between the two groups. Conclusions:Compared with metallic EES, the BVS appears to be associated with both lower efficacy and higher thrombotic risk during the observation period.

Objective To analyze the factors influencing the occurrence of macrosomia so as to provide a theoretical basis for the prevention of macrosomia.Methods The data were selected from the findings of Survey on Prevalence and Risk Factors for Birth Defects in Shaanxi Province.This study intended to select data of macrosomia in Xianyang City and its influencing factors for statistical analysis.The rates were compared by χ2 ;the influencing factors were analyzed by univariate and multivariate Logistic regression.Results The incidence of fetal macrosomia among single live birth neonates in Xianyang was 5.2%.The incidence of macrosomia was 6.5%in males and 4.2% in females,with a significant difference (P <0.001).From 2010 to 2013 the annual incidence rate of macrosomia was 5.4%,6.2%,5.9% and 4.4%,with no significant difference (P =0.151).The incidence rate of macrosomia in urban and rural areas was 6.3% and 5.5%,respectively,without significant difference (P =0.556).The incidence of macrosomia was 3.2% in Binxian County,5.6% in Changwu County,6.7% in Liquan County,5.4% in Qianxian County,8.0% in Wugong County,and 4.2% in Xunyi County,with significant differences (P <0.001).Logistic regression analysis showed that the occurrence of macrosomia was related to the baby's sex,mother's age,the times of pregancy,the time of antenatal care,alcohol intake during pregnancy and father's occupation.Conclusion The incidence of macrosomia of Xianyang from 2010 to 2013 was close to the national average.The sex of baby,mother's age,the times of pregnancy,the times of antenatal care,drinking history during pregnancy and father's occupation may affect the occurrence of macrosomia.

Objective:To investigate the current situation of the use of transjugular intrahepatic portosystemic shunt (TIPS) for portal hypertension, which should aid the development of TIPS in China.Methods:The China Portal Hypertension Alliance (CHESS) initiated this study that comprehensively investigated the basic situation of TIPS for portal hypertension in China through network research. The survey included the following: the number of surgical cases, main indications, the development of Early-TIPS, TIPS for portal vein cavernous transformation, collateral circulation embolization, intraoperative portal pressure gradient measurement, commonly used stent types, conventional anticoagulation and time, postoperative follow-up, obstacles, and the application of domestic instruments.Results:According to the survey, a total of 13 527 TIPS operations were carried out in 545 hospitals participating in the survey in 2021, and 94.1% of the hospital had the habit of routine follow-up after TIPS. Most hospitals believed that the main indications of TIPS were the control of acute bleeding (42.6%) and the prevention of rebleeding (40.7%). 48.1% of the teams carried out early or priority TIPS, 53.0% of the teams carried out TIPS for the cavernous transformation of the portal vein, and 81.0% chose routine embolization of collateral circulation during operation. Most of them used coils and biological glue as embolic materials, and 78.5% of the team routinely performed intraoperative portal pressure gradient measurements. In selecting TIPS stents, 57.1% of the hospitals woulel choose Viator-specific stents, 57.2% woulel choose conventional anticoagulation after TIPS, and the duration of anticoagulation was between 3-6 months (55.4%). The limitation of TIPS surgery was mainly due to cost (72.3%) and insufficient understanding of doctors in related departments (77.4%). Most teams accepted the domestic instruments used in TIPS (92.7%).Conclusions:This survey shows that TIPS treatment is an essential part of treating portal hypertension in China. The total number of TIPS cases is far from that of patients with portal hypertension. In the future, it is still necessary to popularize TIPS technology and further standardize surgical indications, routine operations, and instrument application.

Retraction Note to: J Zhejiang Univ-Sci B (Biomed & Biotechnol) 2019 20(3):238-252. https://doi.org/10.1631/jzus.B1800122. The authors have retracted this article (Guo et al., 2019) because some data from the original literature had not been converted to appropriate units in the paper, which resulted in deviation of the meta-analysis results. For example, for the forest plot used to examine associations between PM exposure and the risk of adverse birth outcomes, the estimates from Brauer et al. (2008), Pedersen et al. (2013), Zhao et al. (2015), and Hansen et al. (2006) were on the originally reported scales of 1 µg/m, 10 µg/m, 10 µg/m, and Inter Quartile Range, respectively. None of these estimates had been converted to 20 µg/m increase scale that was stated in the article. Similar problem exists in the analysis on associations between NO exposure and risk of adverse birth outcomes. Therefore, the results of the meta-analysis are misleading. All authors have agreed to this retraction and express their deepest apologies to the original authors, publishers, and readers.

According to the taste analysis of Pudilan Xiaoyan Oral Liquid, the unpleasant taste of the oral liquid is mainly caused by the inherent taste of Chinese medicine and the taste introduced in the preparation process, which leads to its unpopularity among children. Therefore, aiming at the special children patient group, Xiaoer Pudilan Xiaoyan Syrup was developed via technology optimization and dosage form improvement to improve the unpleasant taste and enhance the medication compliance among children. Based on the material properties of Pudilan Xiaoyan Oral Liquid and Xiaoer Pudilan Xiaoyan Syrup extracts, the authors compared the properties(pH, density, turbidity, viscosity, chromaticity, particle size), taste, content of five quality markers and in vivo pharmacokinetic characteristics of these two preparations, to evaluate the suitability of Xiaoer Pudilan Xiaoyan Syrup. The results showed that compared with those of Pudilan Xiaoyan Oral Liquid, the pH, density, turbidity, viscosity and chromaticity of Xiaoer Pudilan Xiaoyan Syrup were significantly changed, and the unpleasant taste was reduced by 26%; the transfer rate of the main active ingredients chicoric acid was increased, while the transfer rate of baicalin had small difference from that of the oral liquid. In addition, pharmacokinetics revealed that the total absorption amount of baicalin in vivo was higher, and the time to peak T_(max) of baicalin and oroxindin in the syrup and the mean residence time MRT_(last )of corynoline in vivo were significantly prolonged. The absorption degree of Xiaoer Pudilan Xiaoyan Syrup and Pudilan Xiaoyan Oral Liquid in the body was the same: baicalin>oroxindin>corynoline. The new dosage form process was simpler than that of the original dosage form, safe, environmentally friendly, reasonable and feasible, meeting the mass production demand. This provided a basis for the reasonable and scientific optimization of Xiaoer Pudilan Xiaoyan Syrup, and also laid a foundation for its further safe and rational use, so as to expand the clinical application in children.

Several reviews have assessed the relationship between exposure to ambient air pollution and adverse birth outcomes during pregnancy, but the results remain controversial. The objective of this study was to assess this correlation quantitatively and to explore sources of heterogeneity. We included all published case-control or cohort studies that evaluated the correlation between ambient air pollution and low birth weight (LBW), preterm birth (PTB), and small for gestational age (SGA). Analytical methods and inclusion criteria were provided on the PROSPERO website (CRD42018085816). We evaluated pooled effects and heterogeneity. Subgroup analyses (grouped by exposure period, study settings, study design, exposure types, data source, Newcastle-Ottawa quality score (NOS), and adjustment for smoking or meteorological factors) were also conducted and publication bias was examined. The risk of bias in systematic reviews (ROBIS) tool was used to evaluate the overall risk of bias in this review. Forty studies met the inclusion criteria. We observed pooled odds ratios (ORs) of 1.03-1.21 for LBW and 0.97-1.06 for PTB when mothers were exposed to CO, NO₂, NO_x, O₃, PM_2.5, PM₁₀, or SO₂ throughout their pregnancy. For SGA, the pooled estimate was 1.02 in relation to NO₂ concentrations. Subgroup analysis and sensitivity analysis decreased the heterogeneity to some extent, such as the subgroups of continuous measures (OR=0.98 (0.97-0.99), I²=0.0%) and NOS>7 (OR=0.98 (0.97-0.99), I²=0.0%) in evaluating the association between PTB and NO₂. This review was completed with a low risk of bias. High concentrations of air pollution were significantly related to the higher risk of adverse birth outcomes. However, the sources of heterogeneity among studies should be further explored.
