Objective To study the mechanism of pulmonary injury and protective effect of modified ultrafiltration on lung function in infant open heart surgery.Methods According to the wishes of parents,40 cases of congenital heart disease were divided into without modified ultrafiltration control group (C) and modified ultrafiltration group (M),and parents signed informed consent.The cardiopulmonary bypass (CPB) was used without ultrafiltration in Group C,while with modified ultrafiltration in group M.The pneumodynamic parameters and C3a,C5a,TXA2,LT were measured at specific time points.Results The static pulmonary compliance (Cstat) and oxygen index (OI) were lower,and alveolar-arteria oxygen difference (AaDO2) was higher after CPB in the two groups(P ＜ 0.05).At T3,T4 and T5 time points,the Cstat and OI in Group M was higher than that in Group C; AaDO2 in Group M was lower than that in Group C (P ＜0.05).The levels of C3a and C5a were lower after CPB in the two groups; levels of TXA2,LT were higher after CPB in the C groups.At T2,T3,T4 and T5 time points,the TXA2 and LT in Group M were lower than that in Group C(P ＜0.05).Conclusions The pulmonary injury in pediatric open heart surgery may be concerned with the the alexin(C3a,C5a) activation and I/R.The level of C3a and C5a was considered earlier index of inflammatory reaction and pulmonary injury.Modified ultrafiltration improves pulmonary function due to elevating coloid osmotic pressure and degrading the plasma level of TXA2,LT.

Objective:To summarize the diagnosis features of the prenatal genetic diagnosis of fetal renal cystic disease and to explore the clinical feasibility and significance of prenatal genetic diagnosis of congenital cystic nephrosis.Methods:A total of 25 fetuses with congenital renal cystic disease were examined via invasive prenatal diagnosis in Henan Provincial People's Hospital from June 2017 to September 2019. Amniotic fluid samples were extracted by amniocentesis. Chromosomal microarray analysis (CMA) were performed in 17 cases. In addition to CMA, the other 8 cases were analyzed by G-band karyotype. Whole exome sequencing (WES) was performed in 6 cases which got normal results by CMA and karyotype, and highly suspected as hereditary disease.Results:Of the 25 fetuses assessed, 4 cases (16.0%) pathogenic copy number variation (pCNV) were found, including 2 cases of 17q12 deletion, 1 case of 10p15.1p14 deletion and 1 case of 4q21.28q22.1 deletion(including PKD2 gene). There were 8 cases without chromosome abnormality by karyotype analysis. Six clinical WES analysis found NPHS1 gene c.1440+1 G>A and c.925G > T mutations were related to Finnish type congenital nephrotic syndrome in 1 case, PKD1 gene c.6878C>T mutation was related to autosomal dominant polycystic kidney disease (ADPKD) in 1 case, and there was no definitive mutation in 4 cases. Conclusions:CMA and next generation sequencing are powerful tools for accurate diagnosis, treatment and genetic counseling of fetal congenital renal cystic diseases. For congenital cystic nephropathy, genetic detection is helpful to clarify the etiology, and provide more exactly informations for prognosis evaluation, treatment and family genetic counseling.

Sequences of circular RNAs (circRNAs) produced from back-splicing of exon(s) com-pletely overlap with those from cognate linear RNAs transcribed from the same gene loci with the exception of their back-splicing junction (BSJ) sites. Therefore, examination of global circRNA expression from RNA-seq datasets generally relies on the detection of RNA-seq fragments span-ning BSJ sites, which is different from the quantification of linear RNA expression by normalized RNA-seq fragments mapped to whole gene bodies. Thus, direct comparison of circular and linear RNA expression from the same gene loci in a genome-wide manner has remained challenging. Here, we update the previously-reported CIRCexplorer pipeline to version 3 for circular and linear RNA expression analysis from ribosomal-RNA depleted RNA-seq (CIRCexplorer3-CLEAR). A newquantitation parameter, fragments per billion mapped bases (FPB), is applied to evaluate circular and linear RNA expression individually by fragments mapped to circRNA-specific BSJ sites or to linear RNA-specific splicing junction (SJ) sites. Comparison of circular and linear RNA expression levels is directly achieved by dividing FPBcirc by FPBlinear to generate a CIRCscore, which indicates the relative circRNA expression level using linear RNA expression level as the background. Highly-expressed circRNAs with low cognate linear RNA expression background can be readily identified by CIRCexplorer3-CLEAR for further investigation. CIRCexplorer3-CLEAR is publically avail-able at https://github.com/YangLab/CLEAR.

We report herein a case of hepatoid adenocarcinoma of the stomach with liver metastasis. Gastric carcinoma generally presents as adenocarcinoma and rarely shows a hepatoid pattern, which can produce alpha-fetoprotein (AFP). The stomach is one of the common sites at which hepatoid adenocarcinoma has been detected. A 75-year-old female patient was admitted to the hospital with a symptom of epigastric discomfort. Gastrofibroscopy revealed a large tumor occupying the greater curvature of the stomach body. The level of serum AFP was markedly increased. Abdominal computed tomography revealed multiple liver masses. Biopsy samples of the gastric lesion and liver masses finally confirmed her case as hepatoid adenocarcinoma in the stomach with liver metastasis. The AFP-producing gastric carcinoma needs special attention because it often presents with early liver metastasis and has a poor prognosis.

OBJECTIVETo explore a better procedure for transjugular intrahepatic portosystemic shunt (TIPS) in order to improve its safety and to extend its indications.

METHODSTo puncture the right portal branch under sonographic guidance in 20 patients with portal hypertension and gastro-esophageal bleeding. The Teflon sheath with gold marker was put into the portal vein; anterior and lateral portography was made, portal pressure was measured and the gastric coronal vein was embolized. The gold marker was put into the portal vein puncture site and the Rups-100 was guided under the gold marker during the TIPS puncture procedure. Anterior and lateral portography was again made to make sure the puncture site was 2 cm away from the portal vein bifurcation. In some cases a 10F sheath was used to suck the thrombosis in the portal vein, and a balloon was used to dilate the parenchyma channel and then a stent was released smoothly.

RESULTS20 reformed TIPS were successfully performed on all patients and their gastric-esophageal bleedings were controlled immediately. 37 punctures were made in 20 of those cases; the average puncture per patient was 1.85+/-0.67, lower than that of the traditional method. The pressure of the portal vein declined from (30.5+/-1.1) mmHg to (16.9+/-0.9) mmHg, P < 0.05, showing that the difference of portal vein pressure before and after the reformed TIPS was significant. 25 stents were placed, and no complications occurred during the procedure in any of the cases.

CONCLUSIONDirect portal vein puncture portography and gold marker guided TIPS procedure is feasible and safe; the indications of TIPS could be further extended.

OBJECTIVETo examine the changes in 25-hydroxyvitamin D[25-(OH)D] level in children with Henoch-Schönlein purpura (HSP) and its clinical significance.

METHODSA total of 92 HSP children were included in this study, and were divided into HSP nephritis (HSPN) group (31 cases) and HSP group (61 cases) based on the presence or absence of HSPN. Alternatively, the patients were divided into purpura alone group (22 cases), purpura with joint symptoms group (joint symptom group, 24 cases), purpura with gastrointestinal symptoms group (gastrointestinal symptom group, 20 cases), and purpura with joint and gastrointestinal symptoms (mixed group, 26 cases) based on their clinical symptoms. In addition, 42 healthy children were selected as healthy control group. The level of 25-(OH)Din each group was measured using enzyme-linked immunoassay.

RESULTSThe 25-(OH)Dlevel in the HSP and HSPN groups was significantly lower than that in the healthy control group (P<0.05), and the 25-(OH)Dlevel in the HSPN group was significantly lower than that in the HSP group (P<0.05). Although there was no significant difference in the 25-(OH)Dlevel between the joint symptom, gastrointestinal symptom, and mixed groups (P=0.22), the 25-(OH)Dlevel in the three groups was all significantly lower than that in the purpura alone group (P<0.05).

CONCLUSIONSThe level of 25-(OH)Dis reduced in children with HSP, particularly those with HSPN or with joint and gastrointestinal symptoms. Therefore, the reduction in 25-(OH)Dlevel may serve as a predictor of whether HSP is associated with other impairments.

A simple and reliable method of high-performance liquid chromatography with photodiode array detection (HPLC-DAD) was developed to evaluate the quality of a traditional Chinese medicine Sophora flavescens through establishing chromatographic fingerprint and simultaneous determination of five flavonoids, including trifolirhizin, maackiain, kushenol I, kurarinone and sophoraflavanone G. The optimal conditions of separation and detection were achieved on an ULTIMATE XB-C18 column (4.6 mm x 250 mm, 5 microm) with a gradient of acetonitrile and water, detected at 295 nm. In the chromatographic fingerprint, 13 peaks were selected as the characteristic peaks to assess the similarities of different samples collected from different origins in China according to similarity evaluation for chromatographic fingerprint of traditional chinese medicine (2004AB) and principal component analysis (PCA) were used in data analysis. There were significant differences in the fingerprint chromatograms between S. flavescens and S. tonkinensis. Principal component analysis showed that kurarinone and sophoraflavanone G were the most important component. In quantitative analysis, the five components showed good regression (R > 0.999) with linear ranges, and their recoveries were in the range of 96.3% - 102.3%. This study indicated that the combination of quantitative and chromatographic fingerprint analysis can be readily utilized as a quality control method for S. flavescens and its related traditional Chinese medicinal preparations.

OBJECTIVETo evaluate the intervention effect of health education on hypertension knowledge in mid-western rural area of Shandong province.

METHODSA project was launched on chronic disease control in mid-western rural area of Shandong province from 2007 to 2010. The baseline survey was performed using multi-stage random sampling method in 8 counties of mid-western rural area of Shandong province in April, 2007. A total of 20 087 participants aged 25 and above were recruited in the survey to study the relationship between awareness of hypertension and diet, smoking, obesity. Health education focusing on balance diet, physical activity promotion and tobacco control was performed among intervention population. The final evaluation survey using same questionnaire was performed in 2010, classified in intervention (4071 participants) and control (2145 participants) group. Control group was selected from non-intervention town in same county. Intervention and control group shared the same baseline data in 2007 for evaluation. By comparing the changes of hypertension knowledge before and after intervention, the intervention effect was evaluated.

RESULTSAwareness of the relationship between hypertension and diet rose from 34.0% (6830/20 087) at baseline in 2007 to 69.3% (2821/4071) (χ(2) = 1757.30, P < 0.01) of intervention group and 44.8% (961/2145) (χ(2) = 99.30, P < 0.01) of control group in 2010. Awareness of hypertension associated to smoking rose from 25.6% (5142/20 087) at baseline in 2007 to 55.2% (2247/4071) (χ(2) = 1396.59, P < 0.01) in intervention group, 30.9% (662/2145) (χ(2) = 27.83, P < 0.01) in control group in 2010. Awareness of hypertension related to obesity rose from 37.2% (7472/20 087) of the baseline in 2007 to 68.3% (2780/4071) (χ(2) = 1339.27, P < 0.01) in intervention group, 45.1% (967/2145) (χ(2) = 51.14, P < 0.01) in control group in 2010.

CONCLUSIONCommunity comprehensive intervention showed significant effects on hypertension related knowledge improvement in mid-western rural area of Shandong province.

Objective: To observe the clinical efficacy of ginger-partitioned moxibustion plus pediatric massage (tuina) in treating infantile diarrhea due to spleen deficiency. Methods: Ninety infants were randomly divided into a massage plus moxibustion group, a massage group and a drug group by the random number table method, with 30 cases in each group. The intervention was conducted for two consecutive courses. The infants in the massage plus moxibustion group were treated with pediatric massage and ginger-partitioned moxibustion at Shenque (CV 8). The infants in the massage group were treated with pediatric massage alone, while those in the drug group were treated with smecta. The primary and secondary symptom scales were assessed before and after treatment and at the follow-ups, and the total effective rate was evaluated after treatment. Results: The total effective rate in the massage plus moxibustion group was significantly different from that in the massage group and drug group (both P<0.05). After treatment, the scores of primary and secondary symptoms decreased in all three groups, with statistically significant intra-group differences (all P<0.05); the scores of primary symptoms were significantly different between the massage plus moxibustion group and the drug group (P<0.05); the scores of secondary symptoms in the massage plus moxibustion group and the massage group were significantly different from that in the drug group (both P<0.05). The differences in the time to recover normal bowel movement frequency among the three groups were not statistically significant (P>0.05). Conclusion: Ginger-partitioned moxibustion plus pediatric massage compared with pediatric massage or smecta monotherapy shows superior clinical efficacy in treating infantile diarrhea due to spleen deficiency, and has the advantages of appetite improvement, physique strengthening and short course.
