| 2 | Prevalence of Autism Spectrum Disorder in China:A Nationwide Multi-center Population-based Study Among Children Aged 6 to 12 Years显示文摘This study aimed to obtain the first national estimate of the prevalence of autism spectrum disorder(ASD) in Chinese children.We targeted the population of 6 to 12-year-old children for this prevalence study by multistage convenient cluster sampling.The Modified Chinese Autism Spectrum Rating Scale was used for the screening process.Of the target population of 142,086 children,88.5%(n=125,806) participated in the study.A total of 363 children were confirmed as having ASD.The observed ASD prevalence rate was 0.29%(95% CI:0.26%-0.32%) for the overall population.After adjustment for response rates,the estimated number of ASD cases was867 in the target population sample,thereby achieving an estimated prevalence of 0.70%(95% CI:0.64%-0.74%).The prevalence was significantly higher in boys than in girls(0.95%;95% CI:0.87%-1.02% versus 0.30%;95%CI:0.26%-0.34%;P <0.001).Of the 363 confirmed ASD cases,43.3% were newly diagnosed,and most of those(90.4%) were attending regular schools,and 68.8% of the children with ASD had at least one neuropsychiatric comorbidity.Our findings provide reliable data on the estimated ASD prevalence and comorbidities in Chinese children. | Hao Zhou Xiu Xu Weili Yan Xiaobing Zou Lijie Wu Xuerong Luo Tingyu Li Yi Huang Hongyan Guan Xiang Chen Meng Mao Kun Xia Lan Zhang Erzhen Li Xiaoling Ge Lili Zhang Chunpei Li Xudong Zhang Yuanfeng Zhou Ding Ding Andy Shih Eric Fombonne Yi Zheng Jisheng Han Zhongsheng Sun Yong-hui Jiang Yi Wang LATENT-NHC Study Team | 2020 | Neuroscience Bulletin2020，36，9： | 158 |
| 3 | Diagnosis of Helicobacter pylori infection: Current options and developments显示文摘Accurate diagnosis of Helicobacter pylori(H. pylori) infection is a crucial part in the effective management of many gastroduodenal diseases. Several invasive and non-invasive diagnostic tests are available for the detection of H. pylori and each test has its usefulness and limitations in different clinical situations. Although none can be considered as a single gold standard in clinical practice,several techniques have been developed to give the more reliable results. Invasive tests are performed via endoscopic biopsy specimens and these tests include histology,culture,rapid urease test as well as molecular methods. Developments of endoscopic equipment also contribute to the real-time diagnosis of H. pylori during endoscopy. Urea breathingtest and stool antigen test are most widely used noninvasive tests,whereas serology is useful in screening and epidemiological studies. Molecular methods have been used in variable specimens other than gastric mucosa. More than detection of H. pylori infection,several tests are introduced into the evaluation of virulence factors and antibiotic sensitivity of H. pylori,as well as screening precancerous lesions and gastric cancer. The aim of this article is to review the current options and novel developments of diagnostic tests and their applications in different clinical conditions or for specific purposes. | Yao-Kuang Wang Fu-Chen Kuo Chung-Jung Liu Meng-Chieh Wu Hsiang-Yao Shih Sophie SW Wang Jeng-Yih Wu Chao-Hung Kuo Yao-Kang Huang Deng-Chyang Wu | 2015 | World Journal of Gastroenterology2015，21，40： | 66 |
| 4 | Solid-pseudopapillary tumor of the pancreas: Clinical experience and literature review显示文摘AIM: To evaluate the clinical presentations of solidpseudopapillary tumor of the pancreas (SPT) and examine the diagnosis, treatment, low grade malignant potential of this rare disease.METHODS: We retrospectively reviewed a series of seven patients with SPT managed in our hospital between July 1990 and October 2003. Six females and one male with mean age of 31 years (range 13 to 50 years) were diagnosed with SPT at our institution.RESULTS: Clinical presentation included a palpable abdominal mass in two patients and vague abdominal discomfort in another two. Two patients were asymptomatic;their tumors were found incidentally on abdominal sonographic examination for other reasons. The final patient was admitted with hemoperitoneum secondary to tumor rupture. The mean diameter of the tumors in the seven patients was 10.5 cm (range 5 to 20 cm). The lesions were located in the body and tail in five cases and in the head of the pancreas in two. Surgical procedures included distal pancreatectomy (3), distal pancreatectomy with splenectomy (2), pancreaticoduodenectomy (1) and a pylorus-preserving Whipple procedure (1). There were gross adhesions or histological evidence of infiltration to the adjacent pancreas and/or splenic capsule in four cases. None of the patients received adjuvant therapy.The mean follow up was 7 years (range 0.5 to 14 years).One patient developed multiple liver metastases after 14 years of follow up.CONCLUSION: SPT is a rare tumor that behaves less aggressively than other pancreatic tumor. However, in cases with local invasion, long-term follow up is advisable. | Hsueh-Lien Huang Shou-Chuan Shih Wen-Hsiung Chang Tsang-En Wang Ming-Jen Chen Yu-Jan Chan | 2005 | World Journal of Gastroenterology2005，11，9： | 57 |

| 6 | Immunopathogenesis of inflammatory bowel disease显示文摘Crohn’s disease and ulcerative colitis are chronic relapsing immune mediated disorders that results from an aberrant response to gut luminal antigen in genetically susceptible host. The adaptive immune response that is then triggered was widely considered to be a T-helper-1 mediated condition in Crohn’s disease and T-helper-2 mediated condition in ulcerative colitis. Recent studies in animal models, genome wide association, and basic science has provided important insights in in the immunopathogenesis of inflammatory bowel disease, one of which was the characterization of the interleukin-23/Th-17 axis. | David Q Shih Stephan R Targan | 2008 | World Journal of Gastroenterology2008，14，3： | 44 |
| 7 | Immunopathology of inflammatory bowel disease显示文摘Inflammatory bowel disease(IBD)results from a complex series of interactions between susceptibility genes,the environment,and the immune system.The host microbiome,as well as viruses and fungi,play important roles in the development of IBD either by causing inflammation directly or indirectly through an altered immune system.New technologies have allowed researchers to be able to quantify the various components of the microbiome,which will allow for future developments in the etiology of IBD.Various components of the mucosal immune system are implicated in the pathogenesis of IBD and include intestinal epithelial cells,innate lymphoid cells,cells of the innate(macrophages/monocytes,neutrophils,and dendritic cells)and adaptive(T-cells and B-cells)immune system,and their secreted mediators(cytokines and chemokines).Either a mucosal susceptibility or defect in sampling of gut luminal antigen,possibly through the process of autophagy,leads to activation of innate immune response that may be mediated by enhanced toll-like receptor activity.The antigen presenting cells then mediate the differentiation of na?ve T-cells into effector T helper(Th)cells,including Th1,Th2,and Th17,which alter gut homeostasis and lead to IBD.In this review,the effects of these components in the immunopathogenesis of IBD will be discussed. | Kori L Wallace Li-Bo Zheng Yoshitake Kanazawa David Q Shih | 2014 | World Journal of Gastroenterology2014，20，1： | 45 |
| 8 | Eosinophilic gastroenteritis: Clinical experience with 15 patients显示文摘AIM: To evaluate the clinic features of eosinophilicgastroenteritis and to examine the diagnosis, treatment,long-term outcome of this disease.METHODS: Charts with a diagnosis of eosinophilicgastroenteritis from 1984 to 2002 at Mackay Memorial Hospital were reviewed retrospectively. There were 15 patients diagnosed with eosinophilic gastroenteritis. The diagnosis was established in 13 by histologic evaluation of endoscopic biopsy or operative specimen and in 2 by radiologic imaging and the presence of eosinophilic ascites.RESULTS: All the patients had gastrointestinal symptoms and 12 (80 %) had hypereosinophilia (absolute eosinophil count 1 008 to 31 360/cm3). The most common symptoms were abdominal pain and diarrhea. Five of the 15 patients had a history of allergy. Seven patients had involvement of the mucosa, 2 of muscularis, and 6 of subserosa. One with a history of seafood allergy was successfully treated with an elimination diet. Another patient improved spontaneously after fasted for several days. The remaining 13 patients were treated with oral prednisolone, 10 to 40 mg/day initially,which was then tapered. The symptoms in all the patients subsided within two weeks. Eleven of the 15 patients were followed up for more than 12 months (12 to 104 months,mean 48.7), of whom 5 had relapses after discontinuing steroids (13 episodes). Two of these patients required longterm maintenance oral prednisolone (5 to 10 mg/day).CONCLUSION: Eosinophilic gastroenteritis is a rare condition of unclear etiology characterized by relapses and remissions. Short courses of corticosteroids are the mainstay of treatment, although some patients with relapsing disease require long-term low-dose steroids. | Ming-Jen Chen Cheng-Hsin Chu Shee-Chan Lin Shou-Chuan Shih Tsang-En Wang | 2003 | World Journal of Gastroenterology2003，9，12： | 37 |

| 10 | CYP2C19 polymorphism influences Helicobacter pylori eradication显示文摘The known factors that have contributed to the decline of Helicobacter pylori(H.pylori)eradication rate include antibiotic resistance,poor compliance,high gastric acidity,high bacterial load,and cytochrome P450 2C19(CYP2C19)polymorphism.Proton pump inhibitor(PPI)is important in the eradication regimen.The principal enzyme implicated in the metabolism of PPIs is CYP2C19.The effects of PPI depend on metabolic enzyme,cytochrome P450 enzymes,and CYP2C19 with genetic differences in the activity of this enzyme(the homozygous EM,heterozygous EM(Het EM),and poor metabolizer).The frequency of the CYP2C19 polymorphism is highly varied among different ethnic populations.The CYP2C19genotype is a cardinal factor of H.pylori eradication in patients taking omeprazole-based or lansoprazolebased triple therapies.In contrast,the CYP2C19 polymorphism has no significant effect on the rabeprazolebased or esomeprazole-based triple therapies.The efficacy of levofloxacin-based rescue triple therapy might be also affected by the CYP2C19 polymorphism,but CYP2C19 genotypes did not show obvious impact on other levofloxacin-based rescue therapies.Choice of different PPIs and/or increasing doses of PPIs should be individualized based on the pharmacogenetics background of each patient and pharmacological profile of each drug.Other possible factors influencing gastric acid secretion(e.g.,IL-1β-511 polymorphism)would be also under consideration. | Chao-Hung Kuo Chien-Yu Lu Hsiang-Yao Shih Chung-Jung Liu Meng-Chieh Wu Huang-Ming Hu Wen-Hung Hsu Fang-Jung Yu Deng-Chyang Wu Fu-Chen Kuo | 2014 | World Journal of Gastroenterology2014，20，43： | 33 |
| 11 | Adhesive small bowel obstruction: How long can patients tolerate conservative treatment?显示文摘AIM: To evaluate how long patients with small bowel obstruction caused by postoperative adhesions can tolerate conservative treatment.METHODS: The records of patients with small bowel obstruction due to postoperative adhesions were retrospectively reviewed. Data collected included the number of admissions, type of management for each admission,duration of conservative treatment, number of repeat laparotomies, and operative findings.RESULTS: One hundred fifty-five patients with this condition from January 1999 to December 2001, for a total of 293 admissions were enrolled in this study. Medical treatment alone was given in 220 admissions, and repeat laparotomy was performed in 73 admissions. The period of observation in patients managed medically ranged from 2 to 12 days (average: 6.9 days), while for those who underwent surgery,the range was 1 to 14 days (average 5.4 days). At surgery,adhesions were the only finding in 46 cases, while there were intestinal complications in 27, or 9.2 % of all 293admissions. Fever and leukocytosis greater than 15 000/mm3were prediction of intestinal complications.CONCLUSION: With closely monitoring, most patients with small bowel obstruction due to postoperative adhesions could tolerate supportive treatment and recover well averagely within 1 week, although some patients require more than 10 days of observation. | Shou-Chuan Shih Kuo-Shyang Jeng Shee-Chan Lin Chin-Roa Kao Sun-Yen Chou Horng-Yuan Wang Wen-Hsiung Chang Cheng-Hsin Chu Tsang-En Wang | 2003 | World Journal of Gastroenterology2003，9，3： | 26 |

| 14 | Transcatheter arterial embolization treatment in patients with hepatocellular carcinoma and risk of pulmonary metastasis显示文摘AIM: To investigate the relationship between transcatheterarterial embolization (TAE) and pulmonary metastasis insubjects with hepatocellular carcinoma (HCC).
METHODS: A total of 287 patients with HCC followed upfor more than 1 week were included. 102 patients underwenttranscatheter arterial embolization (TAE group) and 185received conservative treatment(control group). Thepatients' chest x-rays and chest CT scans were examinedfor pulmonary metastasis.RESULTS: Patients with TAE had a median survival of 19.3months while that of the control group was only 10.0 months(P<0.05). Pulmonary metastasis occurred in 14 (13.7 %)patients in the TAE group and 14 (7.6 %) patients in the control group, there was no significant difference (P>0.05).The 1-year, 2-year and 5-year cumulative incidence of pulmonary metastasis was 11.8 %, 17.6 % and 24.0 % in the TAE group and 7.0 %, 13.0 % and 21.7 % in the control group, respectively (P>0.05). On the univariate analysis,tumor size, abnormal serum alanine aminotransferase levels and heterogeneity on sonography were significantly associated with pulmonary metastasis. However, on the multivariate analysis, only tumor size was significantly predictive of pulmonary metastasis.CONCLUSION: TAE is effective on prolonging survival of patients with HCC. It does not significantly increase the risk of pulmonary metastasis. Tumor size is the only significant predictive factor associated with lung metastasis. | Shee-Chan Lin Shou-Chuan Shih Chin-Roa Kao Sun-Yen Chou | 2003 | World Journal of Gastroenterology2003，9，6： | 18 |
| 15 | DCE-MRI in hepatocellular carcinoma-clinical and therapeutic image biomarker显示文摘Dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI)enables tumor vascular physiology to be assessed.Within the tumor tissue,contrast agents(gadolinium chelates)extravasate from intravascular into the extravascular extracellular space(EES),which results in a signal increase on T1-weighted MRI.The rate of contrast agents extravasation to EES in the tumor tissue is determined by vessel leakiness and blood flow.Thus,the signal measured on DCE-MRI represents a combination of permeability and perfusion.The semi-quantitative analysis is based on the calculation of heuristic parameters that can be extracted from signal intensity-time curves.These enhancing curves can also be deconvoluted by mathematical modeling to extract quantitative parameters that may reflect tumor perfusion,vascular volume,vessel permeability and angiogenesis.Because hepatocellular carcinoma(HCC)is a hypervascular tumor,many emerging therapies focused on the inhibition of angiogenesis.DCE-MRI combined with a pharmacokinetic model allows us to produce highly reproducible and reliable parametric maps of quantitative parameters in HCC.Successful therapies change quantitative parameters of DCE-MRI,which may be used as early indicators of tumor response to anti-angiogenesis agents that modulate tumor vasculature.In the setting of clinical trials,DCE-MRI may provide relevant clinical information on the pharmacodynamic and biologic effects of novel drugs,monitor treatment response and predict survival outcome in HCC patients. | Bang-Bin Chen Tiffany Ting-Fang Shih | 2014 | World Journal of Gastroenterology2014，20，12： | 15 |

| 17 | Thymoquinone suppresses migration of Lo Vo human colon cancer cells by reducing prostaglandin E2 induced COX-2 activation显示文摘AIM To identify potential anti-cancer constituents in natural extracts that inhibit cancer cell growth and migration.METHODS Our experiments used high dose thymoquinone(TQ) as an inhibitor to arrest Lo Vo(a human colon adenocarcinoma cell line) cancer cell growth, which was detected by cell proliferation assay and immunoblotting assay. Low dose TQ did not significantly reduce Lo Vo cancer cell growth. Cyclooxygenase 2(COX-2) is an enzyme that is involved in the conversion of arachidonic acid into prostaglandin E2(PGE2) in humans. PGE2 can promote COX-2 protein expression and tumor cell proliferation and was used as a control.RESULTS Our results showed that 20 μmol/L TQ significantly reduced human LoV o colon cancer cell proliferation. TQ treatment reduced the levels of p-PI3 K, p-Akt, p-GSK3β, and β-catenin and thereby inhibited the downstream COX-2 expression. Results also showed that the reduction in COX-2 expression resulted in a reduction in PGE2 levels and the suppression of EP2 and EP4 activation. Further analysis showed that TG treatment inhibited the nuclear translocation of β-catenin in LoV o cancer cells. The levels of the cofactors LEF-1 and TCF-4 were also decreased in the nucleus following TQ treatment in a dose-dependent manner. Treatment with low dose TQ inhibited the COX-2 expression at the transcriptional level and the regulation of COX-2 expression efficiently reduced LoV o cell migration. The results were further verified in vivo by confirming the effects of TQ and/or PGE2 using tumor xenografts in nude mice.CONCLUSION TQ inhibits LoV o cancer cell growth and migration, and this result highlights the therapeutic advantage of using TQ in combination therapy against colorectal cancer. | Hsi-Hsien Hsu Ming-Cheng Chen Cecilia Hsuan Day Yueh-Min Lin Shin-Yi Li Chuan-Chou Tu Viswanadha Vijaya Padma Hui-Nung Shih Wei-Wen Kuo Chih-Yang Huang | 2017 | World Journal of Gastroenterology2017，23，7： | 12 |

| 19 | Clinical analysis of multiple primary malignancies in the digestive system: A hospital-based study显示文摘AIM: To analyze the characteristics of multiple primary malignancies (MPMs) of digestive system; including incidence, types of tumor combinations, time intervals between development of multiple tumors, clinical course,and prognostic factors affecting survival and mortality.METHODS: Data from a total of 129 patients treated from January 1991 to December 2000 for pathologically proved MPMs, including at least one originating from the digestive system, were reviewed retrospectively.RESULTS: Among 129 patients, 120 (93.02%) had two primary cancers and 9 (6.98%) had three primary cancers. The major sites of MPMs of the digestive system were large intestine, stomach, and liver. Associated nondigestive cancers included 40 cases of gynecological cancers, of which 31 were carcinoma of cervix and 10cases of genitourinary cancers, of which 5 were bladder cancers. Other cancers originated from the lung, breast,nasopharynx, larynx, thyroid, brain, muscle, and skin.Reproductive tract cancers, especially cervical, ovarian,bladder, and prostate cancers were the most commonly associated non-GI cancers, followed by cancer of the lung and breasts. Forty-three cases were synchronous, while the rest (86 cases) were metachronous cancers. Staging of MPMs and treatment regimes correlated with the prognosis between survival and non-survival groups.CONCLUSION: As advances in cancer therapy bring about a progressively larger percentage of long-term survivors, the proportion of patients with subsequent primary lesions will increase. Early diagnosis of these lesions, based on an awareness of the possibility of second and third cancers, and multidiscipiinary treatment strategies will substantially increase the survival of these patients. | Hui-Yun Cheng Cheng-Hsin Chu Wen-Hsiung Chang Tzu-Chi Hsu Shee-Chan Lin Chuan-Chuan Liu An-Ming Yang Shou-Chuan Shih | 2005 | World Journal of Gastroenterology2005，11，27： | 11 |
| 20 | Indoleamine 2,3-dioxygenase (IDO) is essential for dendritic cell activation and chemotactic responsiveness to chemokines显示文摘Indoleamine 2, 3-dioxygenase (IDO) is a rate-limiting enzyme for the tryptophan catabolism. In human and murine cells, IDO inhibits antigen-specific T cell proliferation in vitro and suppresses T cell responses to fetal alloantigens during murine pregnancy. In mice, IDO expression is an inducible feature of specific subsets of dendritic cells (DCs), and is important for T cell regulatory properties. However, the effect of IDO and tryptophan deprivation on DC func- tions remains unknown. We report here that when tryptophan utilization was prevented by a pharmacological inhibitor of IDO, 1-methyl tryptophan (1MT), DC activation induced by pathogenic stimulus lipopolysaccharide (LPS) or inflam- matory cytokine TNF-α was inhibited both phenotypically and functionally. Such an effect was less remarkable when DC was stimulated by a physiological stimulus, CD40 ligand. Tryptophan deprivation during DC activation also regu- lated the expression of CCR5 and CXCR4, as well as DC responsiveness to chemokines. These results suggest that tryptophan usage in the microenvironment is essential for DC maturation, and may also play a role in the regulation of DC migratory behaviors. | Shih Ling HWANG Nancy Pei-Yee CHUNG Jacqueline Kwai-Yi CHAN Chen-Lung Steve LIN | 2005 | Cell Research2005，15，3： | 11 |
