Abstract
Significance: Venous leg ulcers (VLUs) are the most common venous disease, mainly presenting as open skin lesions on the legs or feet and are an important concern in clinical care settings. Recent Advances: Comprehensive tactics were employed to search electronic databases PubMed, Embase, guideline databases, and society websites were searched for Clinical Practice Guidelines (CPGs) on VLU care. The basic information, recommendations for the VLUs, methodological quality, and reporting quality of VLU's CPGs were extracted and captured in Excel. The quality of each CPG was independently assessed by four researchers using AGREE II instrument and the RIGHT checklist. Critical Issues: This study included 19 CPGs with a combined 23 recommendations. The assessment of VLUs was summarized based on the recommendations of VLUs in 11 major items; six on VLU's diagnosis and six on therapeutic strategies of VLUs. The identified CPGs were of mixed quality, and the highest score based on the scope and purpose was 82.85 ± 11.66, whereas the lowest mean score based on the editorial independence by AGREE II was 59.93 ± 21.50. Regarding the RIGHT checklist, field one (basic information) had the highest reporting rate (84.33%), whereas field five (review and quality assurance) had the lowest quality of CPGs (41.11%). Future Directions: This evidence map provided new perspectives in the presentation of evidence. In addition, the evidence map collected and evaluated the characteristics of published CPGs. Thus, the evidence map enhances our knowledge and promotes the development of trustworthy CPGs for VLUs.

Abstract
An E-band (60-90 GHz) multi-channel Doppler backscattering (DBS) system with X-mode polarization has been installed on the Experimental Advanced Superconducting Tokamak (EAST), which can measure the turbulence at five different radial locations simultaneously. This system can launch 31 fixed microwave frequencies in the range of 60-90 GHz with a 1 GHz interval into the plasma, and five probing signals are selected by employing a reference signal and multiple filters. During experiments, the frequency of the reference signal is tunable in the E-band, and the selected probing signals can be changed as needed without any other adjustments, which can be performed in one shot or between shots. Furthermore, the incident angle can be adjusted from -10° to 20°, and the wavenumber range is 4-25 cm-1 with a wavenumber resolution of Δk/k ≤ 0.35. Ray tracing simulations are employed to calculate the scattering locations and the perpendicular wavenumber. In this article, the hardware design, ray tracing, and initial results obtained from the EAST plasma will be presented.

Abstract
BACKGROUND Good quality of care for inflammatory bowel disease (IBD) depends on high-standard management and facility in the IBD center. Yet, there are no clear measures or criteria for evaluating pediatric IBD (PIBD) center in China. The aim of this study was to develop a comprehensive set of quality indicators (QIs) for evaluating PIBD center in China. METHODS A modified Delphi consensus-based approach was used to identify a set of QIs of structure, process, and outcomes for defining the criteria. The process included an exhaustive search using complementary approaches to identify potential QIs, and two web-based voting rounds to select the QIs defining the criteria for PIBD center. RESULTS A total of 101 QIs (35 structures, 48 processes and 18 outcomes) were included in this consensus. Structure QIs focused on the composition of multidisciplinary team, facilities and services that PIBD center should provide. Process QIs highlight core requirements in diagnosing, evaluating, treating PIBD, and disease follow-up. Outcome QIs mainly included criteria evaluating effectiveness of various interventions in PIBD centers. CONCLUSION The present Delphi consensus developed a set of main QIs that may be useful for managing a PIBD center. Video Abstract.

Abstract
Objective: To summarize the clinical characteristics and treatments of chronic non-bacterial osteomyelitis with autoimmune hepatitis in children. Methods: A child who had chronic non-bacterial osteomyelitis with autoimmune hepatitis was admitted to the Department of Gastroenterology of the Children's Hospital Capital Institute of Pediatrics at April 2022. The clinical data was retrospectively analyzed. Using the keywords of "chronic non-bacterial osteomyelitis""autoimmune hepatitis" in Chinese and English, the literature from database establishment to December 2022 in CNKI, Wanfang, China Biomedical Literature Database and Pubmed was searched. Combined with this case, the clinical characteristics and treatment of chronic non-bacterial osteomyelitis combined with autoimmune hepatitis were analyzed. Results: A 5 years and 3 months girl was admitted to the Department of Gastroenterology of Children's Hospital, Capital Institute of Pediatrics for "transaminase elevated for 1 year and swelling of right maxillofacial area for half a year". The physical examinations at admission found a 4.0 cm × 4.0 cm swelling area with tenderness before the right ear, abdominal distention with visible abdominal wall vein, firm and enlarged liver (10.0 cm below the xiphoid and 4.5 cm below the right ribs), and splenomegaly (Line Ⅰ 10.0 cm, Line Ⅱ 11.5 cm, and Line Ⅲ 25.0 cm). There was no redness, swelling or restriction of the limbs. Laboratory examination found abnormal liver function with alanine aminotransferase 118 U/L, aspartate aminotransferase 227 U/L, γ-glutamyltransferase 360 U/L, and positive direct anti-human globulin test; immunology test found immunoglobulin G 41.60 g/L and a homogeneous type of antinuclear antibody of 1∶1 000; the autoimmune hepatitis antibody test found a positive anti-smooth muscle antibody (1∶100). Liver biopsy showed moderate interfacial inflammation and the patient was diagnosed with autoimmune hepatitis (International Autoimmune Hepatitis Group 19). The imaging findings showed extensive involvement of the bilateral mandible, while the right side was severe. There were expansile bone changes, thinning of the bone cortex, and significant swelling of the surrounding soft tissue in the mandibular body, mandibular angle, and mandibular ramus. After treatment of glucocorticoid, the swelling of the right maxillofacial region disappeared and the transaminase returned to normal. Only one case was reported before in English and none in Chinese. The two cases were both girls whose main clinical features were joint pain and swelling. The previous case started with pain in both knee joints, and developed liver injury during treatment while this case had liver injury as the initial clinical presentation. Besides, the affected sites and degrees of arthritis in the 2 cases were different. After glucocorticoid treatment, the clinical symptoms were alleviated, and transaminases returned to normal. Conclusions: Chronic non bacterial osteomyelitis may involve the liver and manifest as autoimmune hepatitis. Glucocorticoids therapy is effective.

Abstract
Background Patients who are coinfected with human immunodeficiency virus 1 (HIV) and Mycobacterium tuberculosis (TB) benefit from timely diagnosis and treatment. In the present study frequencies of CD3+, CD4+, and CD8+ T cells among peripheral blood mononuclear cells (PBMCs) of patients in the Kashi region of China infected with HIV, TB, and both HIV and TB (HIV-TB) were investigated to provide a basis for rapid identification of coinfected patients. Methods A total of 62 patients with HIV, TB, or HIV-TB who were first hospitalized at our institution were included in the study, as were 30 controls. PBMCs were isolated, and the frequencies of CD3+, CD4+, and CD8+ T cells were determined via flow cytometry. Results The frequency of CD4+ T cells and the CD4/CD8 ratio were significantly lower in the HIV-TB group than in the other three groups. In fever patients the frequency of CD4+ T cells and the CD4/CD8 ratio were significantly lower in the HIV-TB group than in the HIV group and the TB group. In patients who exhibited rapid weight loss there were no significant differences in the frequency of CD4+ T cells or the CD4/CD8 ratio between the groups. The results of treatment were compared in the HIV, TB, and HIV-TB groups after 7 days, and there were obvious improvements in the frequency of CD4+ T cells and the CD4/CD8 ratio. Conclusion Clinical symptoms and the degree of immune injury can heighten suspicion for HIV-TB coinfection.

Abstract
BACKGROUND Cancer-related fatigue is a widely prevalent global public health concern with serious consequences. Increasing evidence suggests the effectiveness of exercise intervention in treating cancer-related fatigue, but there is a lack of a summary of relevant literature on the same to help reach a clear consensus. OBJECTIVE To summarize evidence regarding the efficacy of exercise interventions to reduce cancer fatigue, as determined in systematic reviews (SRs) and/or meta-analyses (MAs). METHOD From inception to September 2022, PubMed (1948-2022), Embase (1974-2022), Cochrane Library (1993-2022), CINAHL (1937-2022), Web of Science (1997-2022), China Knowledge Resource Integrated Database (1999-2022), Wanfang Database (1993-2022), and Chinese Biomedical Database (1994-2022) were searched for inclusion to the study. Two reviewers independently extracted the data from the included articles. AMSTAR II was to evaluate the methodological quality of the reviews. RESULTS A total of 46 systematic reviews were assessed for data on exercise intervention in reducing cancer-related fatigue among cancer patients. In addition, some studies have reported adverse events during the exercise intervention period. The quality of the included systematic review was found to be low or critically low. CONCLUSIONS The present systematic review of systematic reviews supports exercise intervention for reducing cancer-related fatigue. Further higher-quality studies are warranted to improve the level of evidence for exercise interventions for application in the treatment of cancer-related fatigue.

Abstract
Objective: To evaluate the diagnostic value and application of 24 h multichannel intraluminal impedance-pH (24 h MII-pH) monitoring in children with gastroesophageal reflux disease (GERD). Methods: This is a cross-sectional study. From January 2013 to December, 2020, 417 patients who received 24 h MII-pH monitoring in Department of Gastroenterology of Children's Hospital Capital Institute of Pediatrics were included. According to results, these children were divided into the GERD and non-GERD groups. Furthermore, the 132 children with GERD who had gastroscopy were divided into the reflux esophagitis (RE) and non-erosive reflux disease (NE) groups to investigate the differences in their refluxes. Non-parametric Mann-Whitney U test or indepentent sample t test was used for comparisons between the groups. Results: Among the 417 children, 232 were males and 185 females, aged (7.3±3.9) years. The course of disease was 0.5 (0.1, 2.0) years. The main clinical symptoms included acid reflux (128 cases), vomiting (173 cases), abdominal pain (101 cases), and cough (76 cases). The 24 h MII-pH monitoring were positive in 243 children (58.3%, 243/417), which was higher than that by 24 h esophageal pH monitoring (43.6%, 182/417). The 24 h MII-pH monitoring results demonstrated significant differences in the episodes of acid reflux, weakly acidic reflux, non-acidic reflux, liquid reflux and mixed reflux between GERD and non-GERD groups (10 (4, 19) vs. 4 (1, 9) times/24 h, 14 (6, 32) vs. 7 (3, 13) times/24 h, 0 (0, 0) vs. 0 (0, 0) times/24 h, 19 (10, 34) vs. 8 (3, 14) times/24 h, and 6 (2, 12) vs. 3 (1, 5) times/24 h, Z=-6.96, -7.25, -5.62, -8.75, and -6.48, all P<0.05, respectively). Besides, the results also showed significant differences in Boix-Ochoa score, episodes of long reflux, course of long reflux, and episodes of weakly acidic reflux between the RE and NE groups (51.2 (21.4, 153.2) vs. 20.7 (12.1, 34.7), 5 (2, 10) vs. 1 (0, 4) times/24 h, 19 (7, 87) vs. 8 (3, 22) min, and 5 (2, 15) vs. 15 (6, 33) times/24 h, Z=-3.44, -3.41, -2.65, and -2.27, all P<0.05, respectively). Conclusion: 24 h MII-pH monitoring not only improves the detection rate of GERD in children, but also provides a possibility to early etiological diagnosis.

Abstract
Exposure to green space has been proposed to be beneficially associated with cardiovascular morbidity and mortality. Many studies have explored this topic, but the results remain conflicting. We aimed to evaluate the epidemiological evidence on this topic by performing a systematic review with meta-analysis. We searched PubMed, Web of Science and Embase for studies on the association between green space and cardiovascular disease (CVD) that were published till January 2022. Two authors independently performed study selection, data extraction, quality assessment, and risk of bias assessment. For studies providing detailed numeric data, we also conducted quantitative meta-analyses and calculated the pooled odd ratios (ORs) for associations between the most commonly used exposure estimate (normalized difference vegetative index [NDVI]) and five CVD events: CVD mortality, ischemic heart disease (IHD) mortality, cerebrovascular disease (CBVD) mortality, and stroke incidence/prevalence. Additional analyses were conducted to explore the geographical scale effects of NDVI. Publication bias tests were also conducted. Of the 6787 records identified, 53 studies were eligible for inclusion. These studies covered 18 countries and included data from more than 100 million persons. Meta-analyses showed that a 0.1 increase in NDVI was significantly associated with 2-3% lower odds of CVD mortality (OR: 0.97, 95% CI: 0.96-0.99), IHD mortality (OR: 0.98, 95% CI: 0.96-1.00), CBVD mortality (OR: 0.98, 95% CI: 0.97-1.00), and stroke incidence/prevalence (OR: 0.98, 95% CI: 0.96-0.99). There was no significant difference between the pooled estimates for different buffer sizes. No evidence of publication bias was detected. We provide strong and robust evidence for the beneficial effects of green space exposure on cardiovascular health. More prospective studies and mechanistic studies, especially that conducted in low- and middle-income countries, are merited to strengthen our conclusions.

Abstract
Background Kashi city is situated near the Taklamakan desert and has a high incidence rate of chronic obstructive pulmonary disease (COPD). In this study, we aimed to explore the relationship between the SNP of the SREK1 gene locus rs74794265 and the susceptibility to COPD among the Uyghur population in Kashi, XinJiang, China. Methods A total of 541 patients with COPD and 534 control subjects were included in this study. Sanger sequencing was used to analyze the SNP of the SREK1 gene locus rs74794265 site. The distribution of genotypes in different genetic models between the case and control group were analyzed by logistic regression analysis after adjusting for age, sex, and smoking history. Results The SREK1 gene SNP locus rs74794265 included two genotypes, namely, C/C and C/T, of which C/C was the wildtype; The risk of COPD was significantly lower in patients with heterozygous C/T in rs74794265 [p=0.0236, OR=0.3677 (0.1547–0.8742)], and the allele frequency of T was also significantly lower in the patient group [p=0.0245, OR=0.3728 (0.1577–0.8811)]. The heterozygous C/T of rs74794265 among non-smoking COPD patients was significantly lower than other COPD patients [p=0.0298, OR=0.3217 (0.1156–0.8949)], and there was no significant correlation of the heterozygous C/T genotype in smokers. Conclusion We found that the rs74794265 heterozygous C/T genotype significantly reduces the risk of COPD. The C/T genotype is likely a protective factor for COPD in the Kashi region. We speculate that the occurrence of COPD in this area is probably more related to desert climate condition and genetic factors than smoking status.

Abstract
BACKGROUND Glycogen storage disease type Ib (GSD-Ib) is a glycogen metabolism disorder that leads to the manifestations of inflammatory bowel disease (IBD), especially Crohn’s disease (CD)-like colitis. Although biological agents are effective for treating CD, their application in the treatment of GSD-Ib with CD-like colitis has been rarely reported.
CASE SUMMARY A 13-year-old Han male was diagnosed with GSD-Ib with CD. The patient was treated with granulocyte colony-stimulating factor. When he had symptoms of CD-like colitis, he was continuously pumped with enteral nutrition and administered oral mesalazine for 2 wk; however, the symptoms did not improve significantly. Hence, infliximab (IFX) was administered. Hitherto, the patient has been followed up for 1 year, and no clinical manifestations have been observed. After 6 mo of treatment (fifth IFX treatment), the disease activity index and all inflammatory indexes decreased, and a review of the colonoscopy data showed that the ulcers appeared smooth.
CONCLUSION In this study, the patient was successfully treated with IFX. In cases of GSD-Ib, IBD should be highly considered.

Abstract
The cross-polarization scattering (CPS) system for magnetic fluctuation measurements in the Experimental Advanced Superconducting Tokamak (EAST) has been designed and installed. Different from the Doppler reflectometer (DR) system, the CPS system detects the perpendicular polarization of the electromagnetic wave induced by magnetic fluctuations B̃. The CPS system in the EAST has been developed from the existing Doppler reflectometer system, and they are integrated together for simultaneous measurement of magnetic and density fluctuations. Ray-tracing simulations are used to calculate the scattering locations and the wavenumber coverage of the magnetic fluctuation for CPS. In the experiments, the CPS and DR system data were different in Doppler shift, amplitude, and spectrum broadening. In this article, the hardware design, the ray tracing, and the preliminary results of the system in the EAST are presented.

Abstract
Objective: To explore the relationship between the health literacy of employees and smoking, drinking, diet and exercise, and provide scientific basis for health education and targeted intervention. Methods: From February to July 2019, a cluster random sampling method was adopted to select enterprise employees in Shihezi City to conduct a questionnaire survey. Self-made questionnaires and "National Resident Health Literacy Monitoring Questionnaire" were used to assess the social demographics, health literacy, and Health-related behaviors were investigated, and 1053 valid questionnaires were collected. Logistic regression model was used to analyze the relationship between health literacy and the three dimensions with smoking, drinking, diet and exercise. Results: Total score of health literacy of enterprise employees is (42.06±11.03) points and the employee health literacy rate of Shihezi City in 2019 is 19.47%. Univariate analysis showed that non-smokers had higher health literacy and three-dimensional health literacy availability than smokers (P<0.01) ; fewer drinkers had higher health literacy availability than overdrinkers (P<0.05) ; balanced diet health literacy availability The health literacy availability rates in the three dimensions were higher than those in the unbalanced diet (P<0.01) . In the logistic regression analysis, healthy lifestyle and behavioral literacy were independently related to smoking behavior (OR=1.571, P<0.05) ; the presence of health literacy and the three dimensions of health literacy were not statistically related to alcohol consumption (P>0.05) ; there is a statistical correlation between health literacy, healthy lifestyles, behaviors, and health skills and regular exercise among employees (OR=1.829、2.503、1.395, P<0.05) ; employees with health literacy and three dimensions of health literacy are more likely to have a balanced diet (P<0.01) . Conclusion: There is a correlation between the health literacy of enterprise employees and diet and exercise. The improvement of health literacy level is an important way to interfere with unhealthy behaviors.

Abstract
Objective: To analyze the clinical characteristics and efficacy of drug treatment in children with inflammatory bowel disease (IBD) at different ages of onset. Methods: The clinical data of 87 children with IBD admitted to Department of Gastroenterology in Children's Hospital, Capital Institute of Pediatrics from January 2009 to December 2018 were collected. The patients were divided into four groups according to the age of onset: 0 -<2 years old group (36 cases), 2 -<6 years old group (10 cases), 6 -<10 years old group (12 cases) and 10 -<18 years old group (29 cases). The clinical manifestations, laboratory examination, endoscopic findings, pathologic and genetic changes, and treatment were compared among different age groups with chi-square test or Fisher's exact text. Results: (1) A total of 87 patients were diagnosed with IBD, including 50 Crohn's disease (CD) (57%), 25 ulcerative colitis (UC) (29%) and 12 unclassified inflammatory bowel disease (IBD-U) (14%). (2) Patients with fever accounted for 78% (28/36) and 8/10 in the 0 -<2 years old group and 2 -<6 years old group, respectively. Patients with abdominal pain and perianal diseases accounted for 6% (2/36) and 47% (17/36) in the 0 -<2 years old group, and their proportions were significantly different among the four groups (χ(2)=8.369, 40.317 and 13.130, all P<0.05). (3) Leukocytosis, thrombocytosis and anemia were more common in the 0-<2 years old group, seen in 72% (26/36), 31% (11/36) and 81% (29/36), respectively. There were significant differences in the changes of complete blood count among the four groups (χ(2)=21.919, 8.095 and 11.520, all P<0.05). (4) Colonic involvement accounted for 85% (17/20) in the 0 -<2 years old CD patients. While in the CD patients over 6 years old, 61% (14/23) had inflammation of ileum and colon, with a significant difference compared to that in patients under 6 years old (19% (5/27) , χ(2)=9.455, P=0.003). Also, the location of bowel inflammation among the four groups were significantly different (χ(2)=21.120, P<0.01). (5) Noncaseating granulomas were found in 15 (30%) CD patients, and crypt abscess was found in 11 (44%) UC patients. (6) Among the 24 patients whose genes were analyzed by high throughput sequencing, 12 had pathogenic single gene mutation. (7) There were 25 patients treated with total enteral nutrition. Among the 25 patients treated with thalidomide, 20 (80%) had clinical remission or partial remission. Among the 19 CD patients treated with infliximab (IFX), 14 had clinical remission at the 6(th) week of treatment, and the proportion of remission maintenance at the 30(th) week of treatment was 12/14. (8) The rate of clinical remission or partial remission was 64% (23/36) in the 0 -<2 years old group, 8/10 in the 2 -<6 years old group, 11/12 in the 6 -<10 years old group, and 83% (24/29) in the 10 -<18 years old group. Conclusions: The proportion of CD was higher than that of UC in this study. Infant onset inflammatory bowel disease was more likely to present with perianal lesions, and was usually associated with leukocytosis, thrombocytosis and anemia, and has high possibility of single gene mutation. IFX may be effective in treating CD.

Abstract
OBJECTIVE To observe the effect of early intervention of bone-nearby acupuncture (BNA) combined with electroacupuncture (EA) on the expression of histone deacetylase1(HDAC1), histone deacetylase 2 (HDAC2) andμ-opioid recepter (MOR) in dorsal root ganglia (DRG) of bone cancer pain-morphine tolerance (BCP-MT) rats, and to explore its possible mechanism. METHODS A total of 35 SD rats were randomized into a sham BCP group (n=6), a BCP group (n=7), a MT group (n=7), a BNA+EA group (n=8) and a shame BNA group (n=7). Except of the sham BCP group, cancer cell inoculation operation at left tibia was given in the other 4 groups to establish the bone cancer pain model. In the MT group, the BNA+EA group and the shame BNA group, intraperitoneal injection of morphine hydrochloride was given to establish the morphine tolerance model. After the operation, bone-nearby acupuncture combined with electroacupuncture was applied at "Zusanli" (ST 36) and "Kunlun" (BL 60) in the BNA+EA group, with dilatational wave, 2 Hz/100 Hz in frequency, 0.5 to 1.5 mA in intensity. Intervention in the shame BNA group was applied at the same time and acupoints as those in the BNA+EA group, the needles were pierced the skin without any electrical stimulation. The needles were retained for 30 min, once a day for continuous 7 days in both BNA+EA and shame BNA groups. Before and 10, 11, 15, 22 days after the operation, the left paw withdrawal threshold (PWT) was measured in the 5 groups. The levels of HDAC1, HDAC2 and MOR in DRG were detected by Western blot. RESULTS Ten days after the cancer cell inoculation operation, the PWT of the BCP, MT, BNA+EA and sham BNA groups was decreased compared with the sham BCP group (P<0.01). Eleven days after the operation, the PWT of the MT, BNA+EA and sham BNA groups was increased compared with the BCP group (P<0.01). Twenty-two days after the operation, the difference was no significant between the BCP group and MT group (P>0.05); the PWT of the BNA+EA group was increased compared with the MT and sham BNA group (P<0.01). In the BCP group, the DRG levels of HDAC1 and HDCA2 were increased, while the level of MOR was decreased compared with the sham BCP group (P<0.05, P<0.01). In the MT group, the DRG level of HDAC1 was increased compared with the BCP group (P<0.05). In the BNA+EA group, the DRG level of HDAC1 was decreased compared with the MT group and the sham BNA group (P<0.01, P<0.05), while the level of MOR was increased (P<0.01). CONCLUSION Early intervention of bone-nearby acupuncture combined with electroacupuncture can relieve the morphine tolerance in bone cancer pain rats, it may relate to down-regulating the expression of HDAC1 and up-regulating the expression of MOR in the dorsal root ganglia.

Abstract
Intrauterine inflammation is the main reason for neonatal adverse outcomes and normal placenta perfusion plays an important role in fetal development. However, whether inflammation will affect placental angiogenesis and the underlying mechanism are still poorly understood. To investigate lipopolysaccharide (LPS)-induced intrauterine inflammation on placenta angiogenesis and Wnt5a-Flt1 expression. LPS-induced intrauterine inflammation rat model was established. Preterm rat outcomes were analyzed and angiogenesis of placenta villi was calculated by immunohistochemistry (IHC) of CD34 staining, and placenta Wnt5a-Flt1 expression was detected by western blot and IHC. Compared to control group, neonatal rats in LPS group showed higher death rate (1.4% vs 10.1%, p < 0.05) and lower birth weight (6.36 ± 0.48 vs 5.70 ± 0.67, p < 0.01); the villi vessel area and mean diameter in the placenta were significantly reduced in the LPS group (total area %, 16.7% ± 0.6% vs 8.7% ± 0.4%, p < 0.01, n = 9; mean diameter (pixel), 15.6 ± 0.5 vs 12.9 ± 0.3, p < 0.01, n = 9). Placenta Wnt5a-Flt1 expression was upregulated significantly (integrated optical density (IOD) in IHC: Wnt5a, 1667 ± 1204 vs 11,076 ± 4046, p < 0.05; Flt1, 2554 ± 466.2 vs 7998 ± 1613, p < 0.05; western blot: Wnt5a, 0.33 ± 0.05 vs 0.96 ± 0.06, p < 0.05; Flt1, 0.36 ± 0.15 vs 1.08 ± 0.08, p < 0.05). Intrauterine inflammation gave rise to offspring death rate and low birth weight; the mechanism might be disordered placental angiogenesis via Wnt5a-Flt1 activation triggered by inflammation.

Abstract
Nitrogen oxide (NOx) is an important precursor for many air pollution problems such as fine particulate matter and ground-level ozone. Because air pollution levels increase daily, it is important to control NOx emissions from industrial boiler flue gas. A series of different Co3O4 catalysts was prepared in this study by different methods. The effects of the preparation methods on selective catalytic reduction of NO by CO (CO-SCR) were investigated. The catalysts were characterized by BET, XRD, HR-TEM, and Raman. The results show that the Co3O4-S catalyst, prepared by solid grinding with cobalt sulfate as the precursor, had better CO-SCR activity and H2O resistance and that Co3O4-C, prepared by solid grinding with cobalt acetate as the precursor, showed excellent H2O resistance. The NO oxidation results showed that better NO oxidation activity over the catalysts is an important reason for the improved CO-SCR activity. The Raman results indicate that more Co2+ ions appeared on the surface of Co3O4-S, which benefited the formation of oxygen vacancies. The H2-TPR results showed better redox property of the Co3O4-S catalyst. The HR-TEM results shoes that the (111) and (220) crystal planes were exposed mainly on Co3O4-S and Co3O4-O and that more (220) crystal planes are conducive to improved reaction.

Abstract
Objective: To analyze the clinical and genotypic characteristics of infantile inflammatory bowel disease (IBD). Methods: The age of onset, family history, clinical manifestations, and treatment effect were retrospectively analyzed in 39 infants (male 23 cases, female 16 cases) with IBD who were admitted to the Department of Gastroenterology in Children's Hospital, Capital Institute of Pediatrics from January 2007 to December 2017. Next generation sequencing (NGS) based on target gene panel was used for gene analysis in 17 patients. Results: The median age of onset was 0.5 (0.5, 1.0) month. The most common clinical symptoms included diarrhea (39, 100%), malnutrition (38, 97%), hematochezia (34, 87%), fever (25, 64%), and perianal diseases (24, 61%). Four children had associated family history. Among the 17 patients whose gene was analyzed, 10 were found to have the pathogenic gene variation, within whom 7 had interleukin-10 receptor α subunit (IL-10RA) mutation, 2 had CYBB heterozygous mutation, 1 had interleukin-10 receptor β subunit (IL-10RB) mutation. The therapeutic medicine included mesalazine, steroids, and thalidomide. Eighteen children (46%) reached clinical remission (10 cases) or partial remission (8 cases). Conclusions: The incidence of single gene mutation in infants with IBD is high, with IL-10RA mutation as the most common. Refractory diarrhea and malnutrition may indicate infantile IBD.

Abstract
Objective: Prediction of delayed brain edema after spontaneous intracerebral hemorrhage by magnetic resonance spectroscopy combined with diffusion weighted imaging, and to explore the causes and treatment of delayed brain edema after intracerebral hemorrhage. Methods: The patients with spontaneous cerebral hemorrhage diagnosed by CT from January 2015 to June 2018 in our hospital were analyzed. Magnetic resonance spectroscopy and diffusion weighted imaging examinations were performed on the third day after hemorrhage. It was diagnosed as delayed brain edema that the edema range enlarged more than 1 cm in CT scan on the 14th day Compare with the 7th Day. The patients were divided into the delayed brain edema group and the control group(n=27 for each). The NAA/Cr value and rADC value of the edema area in the two groups were analyzed by T test. Results: The NAA/Cr value (1.67±0.38) in the edema area of patients with delayed brain edema was significantly decreased Compare with the control group(1.92±0.42), and the rADC value (2.59±0.42) reduced significantly Compare with the control group (2.93±0.51), the differences were statistically significant (P<0.05). Conclusion: MRS and DWI were susceptive in showing delayed brain edema lesions at hyper-early phase. Combination of MRS and DWI can provide a basis for clinical individual treatment programs selection and prognostic evaluation.

Abstract
Objective: To analyze the causes of complication of early acute kidney injury (AKI) in four severely burned patients, and to explore the related treatment methods. Methods: The clinical data of 4 patients with severe burn complicated with early AKI admitted to Guangzhou Red Cross Hospital Affiliated to Medical College of Jinan University (hereinafter referred to as our hospital) from June 2014 to December 2017 were retrospectively analyzed. All the patients were male, aged 23-33 (30±5) years old, with depth of burns ranged from deep partial-thickness to full-thickness, complicated with myofascial compartment syndrome of extremities and varying degrees of striated muscle injury, and treated in other hospitals before transfer to our hospital. The patients were numbered from small to large according to the total burn area. The total burn area of patients No. 1, 2, 3, and 4 was 10%, 80%, 90%, and 95% total body surface area respectively, their occurrence time of early AKI was 48, 11, 29, and 48 hours after injury respectively, and their time of arriving our hospital was 60, 11, 29, and 144 hours after injury respectively. Hypovolemic shock occurred in patients No. 2 and 3 at admission to our hospital. All the patients received continuous renal replacement therapy (CRRT) after admission to our hospital. Under the support of hemodynamic monitoring and organ function monitoring, the limbs complicated with myofascial compartment syndrome were incised, thorough decompression exploration was performed, and necrotic muscle tissue was removed or amputation was performed. After escharectomy and decompression of limbs, fresh granulation wounds were formed by temporarily covering wounds with Jieya dressing skin or pig skin, multiple debridements, and vacuum sealing drainage. Fresh granulation wounds and other wounds underwent staged eschar excision and shaving were covered with autologous Meek skin graft, particulate skin graft, reticular skin graft and small skin graft respectively. The treatment outcome, CRRT time, operation times, time of recovery of serum creatinine and myoglobin, length of hospital stay, and follow-up were recorded. Results: All the 4 patients were cured after transfer to our hospital. Among them, totally 5 limbs of patients No. 1 and No. 4 underwent amputation because of complication of myofascial compartment syndrome and a large amount of necrotic muscle which could not be preserved. Patients No. 1, 2, 3, and 4 were treated with CRRT for 19, 35, 14, and 25 days respectively and performed with operation for 5, 6, 10, 8 times respectively. Serum creatinine of patients No. 1, 2, 3, and 4 returned to normal on 22, 35, 37, and 48 days after transfer respectively, and their serum myoglobin returned to normal on 18, 28, 25, and 30 days after transfer respectively. Patients No. 1, 2, 3, and 4 were hospitalized for 52, 105, 148, and 156 days and discharged after basic wound healing. Follow-up for 1 to 36 months showed no abnormal renal function in 4 patients. Conclusions: The early AKI in patients No. 1 and 4 was caused by rhabdomyolysis after severe burn complicated with myofascial compartment syndrome, while that of the other 2 cases were also related to hypovolemic shock and poor renal perfusion. The success rate of early AKI treatment in severely burned patients can be effectively improved by removing the causes of diseases at the same time of CRRT and actively treating burn wounds under the support of organ function and hemodynamic monitoring.

Abstract
Objective: To investigate the prognostic effect of neonatal morbidities on poor outcomes at 12 months corrected age in very low birth weight (VLBW) premature infants . Method: From November 2013 to October 2014, a multi-center retrospective study was conducted in 8 tertiary Maternal and Children's hospitals in Guangdong, Hunan and Fujian. The premature infants survived to a postmenstrual age (PMA) of 36 weeks with birth weight less than 1 500 g and without congenital diseases were included, and divided into two groups according to poor outcomes. The birth weight, gestational age, morbidities and poor outcomes (death, cerebral palsy, cognitive delay, et al) were recorded. Data were analyzed with Chi-square test to investigate the relationship between morbidities and poor outcomes. And the predictive effect of the top three morbidities were analyzed by Logistic regression analysis. Result: Total of 834 VLBW premature infants (473 boys and 361 girls) finished the follow-up, whose average gestational age and birth weight were (30.6±1.8) weeks and (1 189±159)g. The incidences of BPD, severe ROP, NEC, brain injury and sepsis were 207 (24.8%), 119 (14.3%), 58 (7.0%), 281 (33.7%) and 124 (14.9%), respectively. There were significant differences between the two groups in the incidences of BPD, severe ROP, NEC, brain injury and sepsis(χ(2)=42.10, 47.20, 4.81, 44.28, 18.63, all P<0.01), which had significant correlation with poor outcomes at 12 months corrected age. The three top morbidities were severe ROP, BPD and brain injury(OR=3.82, 2.90, 2.80). Combined morbidities with BPD, severe ROP and brain injury correlated with higher risk of poor outcomes (one morbidity, OR=3.14, β=1.15; two morbidities, OR=7.31, β=1.99; three morbidities, OR=22.41, β=3.11; all P<0.01). Conclusion: BPD, severe ROP, NEC, brain injury and sepsis were the risk factors of poor outcomes at 12 months corrected age in VLBW infants. And the more combined morbidities with severe ROP, BPD and brain injury, the higher risk of poor outcomes in this population. Trial registration Clinical Trails, NCT03104946.

Abstract
Nandan County is famous for its mining of nonferrous metals. In order to investigate the effects of mining activities on the soil and rice and to evaluate the health risk of the exposure of typical local inhabitants to heavy metals via consumption of rice, a consecutive 3-day household diet survey in four villages in Nandan was conducted. Liuzhai is an uncontaminated contrast area, and Chehe, Dachang, and Zhanglao are contaminated areas. The data for rice consumption rates were obtained. At the same time, 56 soil samples from rice fields and 90 rice samples were collected for the analysis of As, Sb, Cd, Pb, Cu, and Zn. In addition, the potential health risk of the exposure of local people to heavy metals via consumption of the rice was assessed using the pollution index method and the data from the intake of heavy metals. Results showed that the mean contents of As, Sb, Cd, Pb, Cu, and Zn were 58.1, 16.4, 1.22, 49.1, 52.1, and 271 mg·kg-1 in the soil samples from contaminated areas, with higher pollution risks than from the control area for soil heavy metal contents. The Nemero comprehensive contamination index (PN) was 3.14, a heavy pollution grade. Cd contents in rice in Liuzhai, Chehe, Dachang, and Zhanglao were 2.23 times, 4.40 times, 3.81 times, and 3.52 times higher than those of GB 2762-2017.The content in rice exceeds the standard in all four areas. The daily intake (DI) of Cd in the four areas was higher than the provisional tolerable daily intake (PTDI) established by FAO/WHO. This indicates that Cd and As are the major heavy metal elements posing health risks to the health of the inhabitants in the mining areas and that the inhabitants in the mining areas are facing severe risks of exposure to heavy metals.

Abstract
To understand the distribution and risk of soil cadmium (Cd) in the Xijiang River drainage basin in Guangxi, a total of 2512 soil samples were collected nonferrous metal mining area, farmland (paddy soils and dryland soils) and the background soils, in the Xijiang River drainage basin in Guangxi.The results showed that Cd concentration was 0.514 mg·kg-1 in background soils significantly higher than previously resulted(0.148 mg·kg-1)and that in Guangxi background soil(0.267 mg·kg-1). The geometric average concentration of Cd in dryland soils, paddysoils and mining soils was 0.559, 0.787, 5.71 mg·kg-1, respectively, which were significantly higher than background soils. The Cd concentration exceeded the background soils and baseline by 51.2% and 35.2% in dryland soil, 66.7% and 39.6% in paddy soil, 77.8% and 71.4% in mining soil, high Cd concentration occurred in the Nandan County, Dahua County, Duan County, Huanjiang County and Yizhou City, as well as Liujiang County, These regions have developed severe and even extremely serious pollution, medium-high pollution accumulation and higher-extremely high potential ecological risks. The Cd-pollution in soils in agricultural and mining soils in upstream of Xijiang River in Guangxi is serious, due to mining activities and high Cd geological background. People in the mining area and surrounding areas who live on local crops, vegetables, may expose to the Cd-pollution. It is recommended to further develop a Cd risk assessment through a soil-plant-human system, taking appropriate measures to control risk.

Abstract
Background: Previous studies conducted in various geographical and ethnical populations have shown that Alpha-1-antitrypsin (Alpha-1-AT) expression affects the occurrence and progression of chronic obstructive pulmonary disease (COPD). We aimed to explore the associations of rs9944155AG, rs1051052AG, and rs1243166AG polymorphisms in the Alpha-1-AT gene with the risk of COPD in Uygur population in the Kashgar region. Methods: From March 2013 to December 2015, a total of 225 Uygur COPD patients and 198 healthy people were recruited as cases and controls, respectively, in Kashgar region. DNA was extracted according to the protocol of the DNA genome kit, and Sequenom MassARRAY single-nucleotide polymorphism technology was used for genotype determination. Serum concentration of Alpha-1-AT was detected by enzyme-linked immunosorbent assay. A logistic regression model was used to estimate the associations of polymorphisms with COPD. Results: The rs1243166-G allele was associated with a higher risk of COPD (odds ratio [OR] = 2.039, 95% confidence interval [CI]: 1.116–3.725, P = 0.019). In cases, Alpha-1-AT levels were the highest among participants carrying rs1243166 AG genotype, followed by AA and GG genotype (χ2 = 11.89, P = 0.003). Similarly, the rs1051052-G allele was associated with a higher risk of COPD (OR = 19.433, 95% CI: 8.783–43.00, P < 0.001). The highest Alpha-1-AT levels were observed in cases carrying rs1051052 AA genotype, followed by cases with AG and GG genotypes (χ2 = 122.45, P < 0.001). However, individuals with rs9944155-G allele exhibited a lower risk of COPD than those carrying the rs9944155-A allele (OR = 0.121, 95% CI: 0.070–0.209, P < 0.001). In both cases and controls, no significant difference in Alpha-1-AT levels was observed among various rs9944115 genotypes. Conclusions: rs1243166, rs9944155, and rs1051052 sites of Alpha-1-AT may be associated with the COPD morbidity in Uygur population. While rs1243166-G allele and rs1051052-G allele are associated with an increased risk of developing COPD, rs9944155-G allele is a protect locus in Uygur population. Alpha-1-AT levels in Uygur COPD patients were lower than those in healthy people and differed among patients with different rs1051052 AG and rs1243166 AG genotypes.

Abstract
Neuroglioma is associated with high rates of malignancy, metastasis, and recurrence. Recently, research on the roles of microRNAs (miR) in cancer prognosis has formed an important area of research as differential expression of miRNAs has been observed in different cancers. However, the detailed mechanism by which miRNAs regulate glioma remains unknown. Thus, we investigated the effect of miR-1 on human glioma by inhibiting the expression of miR-1. Anti-miR-1, an anti-sense oligonucleotide against miR-1, significantly reduced the level of miR-1 in the human glioma cell line U87 (P < 0.05). Further, cell proliferation and colony formation assays were used to determine the effect of miR-1 on cell growth. The scratch assay and cell migration assay were performed to evaluate cell invasion. Our data demonstrated that the growth of glioma cells was impeded due to the decrease in miR-1 levels, compared to the untransfected control cells (P < 0.05). Interestingly, the invasion and mobility of the cells were also retarded after transfection with anti-miR-1 (P < 0.05). In conclusion, our results indicate that the down-regulation of miR-1 significantly inhibited cell proliferation and reduced cell motility, suggesting that anti-miR-1 could be used as a therapeutic intervention tool to counter the activity of neuroglioma cells.

Abstract
Nandan county is usually called "land of nonferrous metals". In order to discuss the impact of mining activities on the health of inhabitants in Nandan county, 200 human hair samples were collected from 4 villages (Liuzhai is a uncontaminated contrast areas, Chehe, Dachang and Zhanglao are contaminated areas) of Nandan and analyzed for contents of As, Sb, Cd, Pb, Cu and Zn. The results showed that the average contents of As, Sb, Cd and Pb were 1.260, 2.161, 2.466 and 20.92 μg·g-1 in the human hair samples from contaminated areas. They were 4.0, 20, 2.1 and 1.9 times higher than those in the contrast areas, and the Sb contents in human hair of Chehe and Dachang were higher than the recommended normal range. The contents of human hair Zn showed a negative correlation with the age of people (P<0.05), and contents of human hair Cd and Pb showed a weak negative correlation with the age of people in contaminated areas (P<0.1). The independent-samples t-test showed that Cd contents in male hair were apparently higher than those in female hair (P<0.05), however, Cu and Zn contents in female hair were apparently higher than those in male hair (P<0.05), in the contaminated areas. There were positive correlations between As and Sb, Cd and Pb, as well as As and Cd (P<0.01), while other elements showed no significant correlation between pairs. It was therefore concluded that contamination from the mining activities has exposed a serious threat to human health in the mine contaminated areas in Nandan county.

Abstract
OBJECTIVE To make genetic diagnosis of Alagille syndrome (ALGS) patients using target gene sequence capture and next generation sequencing technology. METHOD Target gene sequence capture and next generation sequencing were used to detect ALGS gene of 4 patients. They were hospitalized at the Affiliated Hospital, Capital Institute of Pediatrics between January 2014 and December 2015, referred to clinical diagnosis of ALGS typical and atypical respectively in 2 cases. Blood samples were collected from patients and their parents and genomic DNA was extracted from lymphocytes. Target gene sequence capture and next generation sequencing was detected. Sanger sequencing was used to confirm the results of the patients and their parents. RESULT Cholestasis, heart defects, inverted triangular face and butterfly vertebrae were presented as main clinical features in 4 male patients. The first hospital visiting ages ranged from 3 months and 14 days to 3 years and 1 month. The age of onset ranged from 3 days to 42 days (median 23 days). According to the clinical diagnostic criteria of ALGS, patient 1 and patient 2 were considered as typical ALGS. The other 2 patients were considered as atypical ALGS. Four Jagged 1(JAG1) pathogenic mutations were detected. Three different missense mutations were detected in patient 1 to patient 3 with ALGS(c.839C>T(p.W280X), c. 703G>A(p.R235X), c. 1720C>T(p.V574M)). The JAG1 mutation of patient 3 was first reported. Patient 4 had one novel insertion mutation (c.1779_1780insA(p.Ile594AsnfsTer23)). Parental analysis verified that the JAG1 missense mutation of 3 patients were de novo. The results of sanger sequencing was consistent with the results of the next generation sequencing. CONCLUSION Target gene sequence capture combined with next generation sequencing can detect two pathogenic genes in ALGS and test genes of other related diseases in infantile cholestatic diseases simultaneously and presents a high throughput, high efficiency and low cost. It may provide molecular diagnosis and treatment for clinicians with good clinical application prospects.

Abstract
Chinese cabbage (Brassica rapa ssp. pekinensis) is one of the most important vegetable crops grown worldwide, and various methods exist for selection, propagation, and cultivation. The entire Chinese cabbage genome has been sequenced, and the heat shock transcription factor family (Hsfs) has been found to play a central role in plant growth and development and in the response to biotic and abiotic stress conditions, particularly in acquired thermotolerance. We analyzed heat tolerance mechanisms in Chinese cabbage. In this study, 30 Hsfs were identified from the Chinese cabbage genome database. The classification, phylogenetic reconstruction, chromosome distribution, conserved motifs, expression analysis, and interaction networks of the Hsfs were predicted and analyzed. Thirty BrHsfs were classified into 3 major classes (class A, B, and C) according to their structural characteristics and phylogenetic comparisons, and class A was further subdivided into 8 subclasses. Distribution mapping results showed that Hsf genes were located on 10 Chinese cabbage chromosomes. The expression profile indicated that Hsfs play differential roles in 5 organs in Chinese cabbage, and likely participate in the development of underground parts and regulation of reproductive growth. An orthologous gene interaction network was constructed, and included MBF1C, ROF1, TBP2, CDC2, and HSP70 5 genes, which are closely related to heat stress. Our results contribute to the understanding of the complexity of Hsfs in Chinese cabbage and provide a basis for further functional gene research.

Abstract
BACKGROUND Mutations in fumarylacetoacetate hydrolase (FAH) gene can lead to tyrosinemia type 1 (HT1), a relatively rare autosomal recessive disorder. To date, no molecular genetic defects of HT1 in China have been described. We investigated a Chinese family with a HT1 child to identify mutations in FAH. METHODS DNA sequencing was used for mutations screening in FAH gene. Real-time polymerase chain reaction (PCR) was performed to determine the FAH gene expression level. To confirm the presence of degradation by the nonsense-mediated mRNA decay pathway (NMD), the fragments containing R237X mutations were analyzed by primer introduced restriction analysis-polymerase chain reaction (PIRA-PCR) and cDNA sequencing. Finally, the effects of the mutations reported in this study were predicted by online softwares. RESULTS A boy aged 3 years and 8 months was diagnosed clinically with HT1 based on his manifestations and biochemical abnormalities. Screening of FAH gene revealed two heterozygous mutations R237X and L375P transmitted from his mother and father respectively. In this pedigree, the amount of FAH mRNA relative to a healthy control was 0.44 for the patient, 0.77 for his mother and 1.07 for his father. Moreover, both PIRA-PCR and cDNA sequencing showed significant reduction of the FAH mRNA with R237X nonsense mutation. The missense mutation of L375P was not reported previously and prediction software showed that this mutation decreased the stability of protein structure and affected protein function. CONCLUSIONS This is the first case of HT1 analyzed by molecular genetics in China. The R237X mutation in FAH down- regulates the FAH gene expression, and the L375P mutation perhaps interrupts the secondary structure of FAH protein.

Abstract
In order to produce relatively large amounts of recombinant human intestinal trefoil factor and assess its biological activity. The expression plasmid pPIC9-hITF containing AOX1 promotor and the sequences of secreting signal peptides was transformed into the yeast cells. Then through selection, positive transformants were cultivated in fermentation basal salts medium in a 5L fermenter to obtain large amount product with low cost. The secreted peptides were then purified by a combination of ionic exchange chromatography and molecular sieve. To verify the product, electrospray mass spectrometry analyses was used to determine the structure of rhITF and Western Blotting was performed to test the immunological activity. Furthermore, the biological activity of the peptide was examined by experiments from cell to tissue. The nucleotide sequence of rhITF was the same as expected. With a 5-L fermenter, 253mg of hITF was isolated at the purity of 96% from 3.5 L of yeast fermentation broth. The expression level for recombinant human ITF in this yeast system was 73.33mg/L. In our study, we provided a way to gain a production among milligram to gram of recombinant human ITF by the use of a yeast expression system. As human ITF are difficult to purify in any significant amount from tissue extraction, the way described may become a valuable tool in obtaining pure peptide for further studies of trefoil peptide function.
