The study summarizes the clinical experience of surgical treatments of various types of thoracic aneurysm and aortic dissection. Clinical data of 122 patients with thoracic aneurysm and aortic dissection during July 2005 to July 2008 were retrospectively analyzed. The elective operations were performed in 107 patients while emergency surgery was done in 15 cases. Different surgical strategies were employed on the basis of diseased region, including simple ascending aortic replacement (n=3), aortic root replacement (n=43), hemi-arch replacement /total arch replacement+elephant trunk technique (n=32), thoracic/thoracoabdominal aortic replacement (n=8) and endovascular repair (n=36). In this series, there is 4 cases of perioperative death due to massive cerebral hemorrhage (n=1), respiratory failure (n=1) and multiple organ dysfunction syndrome (MODS) (n=2). Three cases developed post-operative massive cerebral infarction and the relatives of the patients abandoned treatment. Instant success rate of endovascular repair was 100%. The intimal rupture was sealed. Blood flow was unobstructed in true lumen and no false lumen was visualized. It was concluded that aggressive surgery should be considered in the patients with thoracic aneurysm and aortic dissection. Surgical procedures should vary with the location and the nature of the lesions.

<b>Objective:b> To understand the prevalence of major human parasitic diseases and related factors in Henan province. <b>Methods:b> This stratified sampling survey was carried out according to the requirement of national survey protocol of major human parasitic diseases, 2014-2015. The prevalence of soil-transmitted helminths infection, taeniasis and intestinal protozoiasis were surveyed in 104 sites selected from 35 counties (districts) and the prevalence of clonorchiasis was surveyed in 62 sites selected from 37 townships. In each survey spot, 250 persons were surveyed. A total of 26 866 persons and 15 893 persons were surveyed. Modified Kato-Katz thick smear was used to detect the eggs of intestinal helminthes. Tube fecal culture was used to identify the species of hookworm. The Enterobius eggs were detected in children aged 3 to 6 years by using adhesive tape. The cyst and trophozoite of intestinal protozoa were examined with physiological saline direct smear method and iodine stain method. <b>Results:b> The overall infestation rate of intestinal parasites was2.02% in Henan, and the worm infection rate was higher than protozoa infection rate. Fourteen kinds of intestinal parasites were found, including nematode (5 species), trematode (2 species), and protozoan (7 species). The infection rate of Enterobius vermicularis was highest, and Qinba Mountain ecological area had the highest infestation rate of intestinal parasites in 4 ecological areas of Henan. There was no significant difference in intestinal parasite infection rate between males and females (χ(2)=3.630, P=0.057), and the differences in intestinal parasite infection rate among different age groups had significance (χ(2)=124.783, P=0.000 1). The infection rate reached the peak in age group ≤9 years and the major parasite was Enterobius vermicularis. Furthermore the overall human infection rate of parasite showed a downward trend with the increase of educational level of the people (χ(2)=70.969, P=0.000 1), the differences had significance (χ(2)=120.118, P=0.000 1). For different populations, the infection rate of intestinal parasites was highest among preschool children. The infection of intestinal helminth was mainly mild, only 2 severe cases were detected. The infection rate of Clonorchis sinensis in urban residents was only 0.006%. Logistic regression analysis showed that being preschool children (χ(2)=15.765, P=0.000 1) and drinking well water (χ(2)=45.589, P=0.000 1) were the risk factors for intestinal parasite infection, and annual income per capita of farmers was the protective factor against intestinal parasite infection. The infection rates of protozoa and intestinal parasites decreased sharply compared with the results of previous two surveys, and the rate of intestinal helminth infection also dropped sharply compared with the second survey. The numbers of protozoa, helminth and intestinal parasites detected in this survey were all less than the numbers found in the previous two surveys. <b>Conclusions:b> Compared the results of three surveys in Henan, the infection rate of protozoa and intestinal parasites showed a downward trend. The prevention and treatment of Enterobius vermicularis infection in children should be the key point of parasitic disease control in the future.

<b>Objective:b> To explore the relationship between different dimensions of infectious disease-specific health literacy scale in China. <b>Methods:b> Structural equation model (SEM) was employed to assess the psychometric properties of the infectious disease-specific health literacy scale. Based on the database from a randomly selected sample of 4 499 adult residents in three provinces in China, from March to May 2015. AMOS 21.0 software was used to build the SEM for data analyses. <b>Results:b> SEM analyses showed a good model fit of data, with the following satisfied parameters: goodness-of-fit index was 0.969, adjusted goodness-of-fit index was 0.962, root mean square residual was 0.038, root mean square error of approximation was 0.038, standardized root mean square residual was 0.032, Tacker-Lewis index/non-normed fit index was 0.926, comparative fit index was 0.934, normed fit index was 0.925, relative fit index was 0.915, incremental fit index was 0.934, parsimony goodness-of-fit index was 0.782, parsimony-adjusted normed fit index was 0.817, parsimony-adjusted comparative fit index was 0.825 and critical N was 702. The established SEM showed that the total influence path coefficient of "infectious disease-related knowledge and values" on the "infectious disease prevention" , "management or treatment of infectious diseases" and "identification of infection sources" were 0.771, 0.744 and 0.843, respectively. The total influence path coefficients of "identification of infection sources" , "infectious disease prevention" on "management or treatment of infectious diseases" were 0.164 and 0.535, respectively. The effect of "infectious disease-related knowledge and values" on "management or treatment of infectious diseases" appeared the greatest (55.4%), followed by "infectious disease prevention" (28.6%) and "identification of infection sources" (2.7%). <b>Conclusion:b> This SEM could be optimistically used for planning and evaluation of health education and promotion programs on infectious diseases prevention.

Objective:b> To explore the difference in intensive care unit (ICU) readmission rate between high dependency unit (HDU) and general ward for the patients with severe liver disease (SLD), and reflect the effect of HDU on SLD patientse. Methods:b> A clinical cohort of patients transferred out of ICU was established, and patients with severe liver disease who were transferred to HDU& general ward from July 2017 to December 2021 in the intensive care Unit of the Fifth Medical Center of PLA General Hospital were continuously enrolled. The main liver function indexes and MELD scores between the two groups were compared. Analyze the differences in severity and ICU readmission rate of SLD patients transferred to different wards, and clarify the role of HDU in the management of SLD patient. Area under the receiver operating characteristic (AUROC) was used to investigate the value of MELD score in predicting the occurrence of return to ICU. Results:b> The level of INR, TB, ALT and MELD scores of SLD patients transferred to HDU were significantly higher than those of patients transferred to general ward (all P < 0.05). MELD > 17 was found in 70.7% of SLD patients transferred to HDU group, while MELD ≤ 17 was found in 61.9% of SLD patients in general ward group. The ICU readmission rate of all patients in this cohort was 11.4%. By MELD quartile stratification, patients with SLD whose MELD > 23 had a significantly higher ICU readmission rate (20.0%) than those with SLD whose MELD ≤ 23 (8.6%) (P = 0.020). The ICU readmission rate was 8.2% when MELD ≤ 23 in the HDU group and 9.1% when MELD > 23, showing no significant difference (P = 1.000). The ICU readmission rate was 8.8% when MELD ≤ 23 in the general ward group. ICU reentry rate increased significantly to 36.4% when MELD > 23 (P = 0.001). MELD Score predicts that the optimal cut-off value of SLD patients in general ward readmitted to ICU was 23.5. Conclusion:b> The high dependency unit could better admit patients with SLD who were transferred out of ICU and required step-down treatment, and significantly reduced the ICU readmission rate of patients with SLD who were transferred out of ICU with MELD > 23. The patients with SLD and MELD score > 23 are suitable to be transferred from ICU to HDU.

<b>OBJECTIVEb>A randomized trial of breast self-examination (BSE) program was carried out to evaluate whether the intensive BSE can reduce the death number of women from breast cancer.

<b>METHODSb>A total of 266,064 women (age of 30 to 64 years) associated with 519 textile factories in Shanghai had been randomly assigned to a BSE instruction group (132,979 women) or a control group (133,085 women) since 1989. Initial instruction in BSE group included demonstration of proper palpation techniques. It was followed by 2 reinforcement sessions during the subsequent 4 years including video shows, BSE instruction sessions and BSE practice under medical supervision. These activities were continued for 5 years. Attendance at all events was recorded. The cohort was followed through July 2000 for development of breast diseases, and the breast cancer cases were followed up through 2001 for vital status. The data analysis methods used included Kaplan-Meier plots, Log-rank test and Cox modeling.

<b>RESULTSb>Among women under instruction, 864 breast cancers were detected and 133 breast cancer deaths occurred, and 896 breast cancers were detected and 130 deaths recorded in the control group. The tumor size (P = 0.07), TNM stage (P = 0.39) and cumulative breast cancer mortality rate (P = 0.72) were not significantly different between the 2 groups. However, more and smaller fibroadenomas were detected in the instruction group than in the control group (P < 0.01).

<b>CONCLUSIONb>Intensive instruction in BSE can not reduce mortality rate of breast cancer, but more and smaller benign breast lumps can be detected.

<b>OBJECTIVEb>To establish baseline patterns of rotavirus diarrhea and to describe its epidemiologic features in Changchun city, prior to rotavirus vaccine immunization.

<b>METHODSb>Hospital-based surveillance was conducted among children under 5 years old with acute diarrhea in Changchun Children's Hospital. Fecal samples were determined to identify rotavirus by PAGE and/or ELISA. G serotypes of rotavirus were identified by ELISA and/or nested RT-PCR. P genotyping were carried out by RT-PCR. All data were computerized and analysed by "Generic Manual on Rotavirus Surveillance" set by CDC in the USA.

<b>RESULTSb>In total, 2 343 diarrhea cases were screened and 1 211 fecal samples were collected. Rotavirus was detected in 31.0% among outpatients and 52.9% in inpatients. During the peak of the season (November through March), 58.6% of diarrhea was caused by rotavirus among inpatients. 95.0% of rotavirus diarrhea cases occurred among children aged < 2 years. The predominant strain was serotype G1 (82.4%), followed by G2 (5.0%), G3 (3.3%), G4 (0.9%). P genotyping showed that P[8] and P[4] were the most common ones. Nine different P-G combinations were identified, four strains (P[8]G1, P[4]G2, P[8]G3, and P[8]G4) commonly seen worldwide accounted for 75.6% of the total. Taken together with uncommon strains, including the novel types P[4]G4 and P[8]G2, it highlights the extraordinary diversity of rotaviruses circulating in China.

<b>CONCLUSIONb>Rotavirus is the major cause of severe child diarrhea in Changchun. Developing a rotavirus vaccine for prevention of severe disease and reduction of treatment costs seemed to be necessary.

<b>BACKGROUNDb>Durable polymers used for first-generation drug-eluting stents (DES) potentially contribute to persistent inflammation and late DES thrombosis. We report the first in human experience with the rapamycin-eluting biodegradable polymer coated cobalt-chromium FIREHAWK stent with abluminal groove.

<b>METHODSb>A total of 21 patients with stable or unstable angina, or prior myocardial infarction, with single de novo native coronary stenoses < 30 mm in length in vessel sizes ranging from 2.25 to 4.0 mm were enrolled. The primary endpoint was major adverse cardiac events (MACE) at 30 days defined as the composite of cardiac death, myocardial infarction (Q and non-Q), or ischemia-driven target lesion revascularization. Secondary endpoints include device, lesion, and clinical success rates, 4-month in-stent late lumen loss by quantitative coronary angiography (QCA), proportion of uncovered or malapposed stent struts by optical coherence tomograpphy (OCT) at 4 months, and MACE at 4, 12, 24 and 36-month follow-up.

<b>RESULTSb>Device success was 95.7%, lesion and clinical success was 100.0%. There were no MACE events at 30 days. One patient died of non-cardiac hemorrhagic stroke 5 days after index procedure. At 4 months, in-stent late loss was (0.13 ± 0.18) mm, and complete strut coverage was 96.2% by OCT with 0.1% strut malapposition. At 4-month follow-up there was no additional MACE events, and a single target vessel (non-target lesion) revascularization.

<b>CONCLUSIONSb>The FIREHAWK abluminal groove biodegradable polymer rapamycin-eluting stent demonstrated feasibility, safety and efficacy in this first in human experience. OCT findings indicated excellent stent strut coverage 4 months after implantation. Larger studies are required to confirm whether the early FIREHAWK stent results translate into longer term restenosis and thrombosis benefits.

<b>BACKGROUNDb>The receptor tyrosine kinase-like orphan receptor 2 (ROR2) gene has been recently shown to play important roles in palatal development in animal models and resides in the chromosomal region linked to non syndromic cleft lip with or without cleft palate in humans. The aim of this study was to investigate the possible association between ROR2 gene and non-syndromic oral clefts.

<b>METHODSb>Here we tested 38 eligible single-nucleotide polymorphisms (SNPs) in ROR2 gene in 297 non-syndromic cleft lip with or without cleft palate and in 82 non-syndromic cleft palate case parent trios recruited from Asia and Maryland. Family Based Association Test was used to test for deviation from Mendelian inheritance. Plink software was used to test potential parent of origin effect. Possible maternally mediated in utero effects were assessed using the TRIad Multi-Marker approach under an assumption of mating symmetry in the population.

<b>RESULTSb>Significant evidence of linkage and association was shown for 3 SNPs (rs7858435, rs10820914 and rs3905385) among 57 Asian non-syndromic cleft palate trios in Family Based Association Tests. P values for these 3 SNPs equaled to 0.000068, 0.000115 and 0.000464 respectively which were all less than the significance level (0.05/38 = 0.0013) adjusted by strict Bonferroni correction. Relevant odds ratios for the risk allele were 3.42 (1.80 - 6.50), 3.45 (1.75 - 6.67) and 2.94 (1.56 - 5.56), respectively. Statistical evidence of linkage and association was not shown for study groups other than non-syndromic cleft palate. Neither evidence for parent-of-origin nor maternal genotypic effect was shown for any of the ROR2 markers in our analysis for all study groups.

<b>CONCLUSIONb>Our results provided evidence of linkage and association between the ROR2 gene and a gene controlling risk to non-syndromic cleft palate.

<b>OBJECTIVEb>To study the association of single nucleotide polymorphisms (SNPs) of transcription factors (NKX2.5, GATA4, TBX5, and FOG2) with congenital heart disease (CHD) in the Chinese population.

<b>METHODSb>PubMed, Google Scholar, CNKI, Wanfang Data, and Weipu Data were searched for articles on the association of SNPs of target genes with CHD in the Chinese population. If one locus was mentioned in at least two articles, the random or fixed effect model was used to perform a pooled analysis of study results and to calculate the pooled OR and its 95%CI. If a locus was mentioned in only one article, related data were extracted from this article to analyze the association between the SNPs of this locus and CHD.

<b>RESULTSb>Twenty-three articles were included. The Meta analysis showed that there were significant differences between the CHD and control groups in the genotype and allele frequencies of GATA4 rs1139244 and rs867858 and the genotype frequency of GATA4 rs904018, while there were no significant differences in the SNPs of the other genetic loci between the two groups. The single-article analysis showed that there were significant differences between the two groups in the allele frequencies of NKX2.5 rs118026695/rs703752, GATA4 rs884662/rs12825/rs12458/rs3203358/rs4841588, and TBX5 rs6489956. There were no significant differences in the SNPs of FOG2 locus between the two groups.

<b>CONCLUSIONSb>The SNPs of some loci in NKX2.5, GATA4, and TBX5 are associated with CHD in the Chinese population, but the association between the SNPs of FOG2 locus and the development of CHD has not been found yet.
