2Eleven COVID-19 Outbreaks with Local Transmissions Caused by the Imported SARS-CoV-2 Delta VOC-China,July-August,2021显示文摘Starting from December 2019,Wuhan,China,encountered the first outbreak of coronavirus disease 2019(COVID-19)(1-2).The epidemic was successfully suppressed by strict containment so that the number of infected people was reduced to 0 on April 8,2020(3–4).After that,China experienced roughly 3 dozen outbreaks with local transmission caused by imported severe acute respiratory syndrome coronavirus 2(SARS-CoV-2).Lei Zhou Kai Nie Hongting Zhao Xiang Zhao Bixiong Ye Ji Wang Cao Chen Hong Wang Jiangli Di Jinsong Li Chao Li Zhixiao Chen Ruiqi Ren Peihua Niu Hui Chen Tao Chen Yali Wang Lili Li Bingxue Han Ruhan A Si Chen Dan Li Dan Li Chunxia Jin Xin Zhang Jiangmei Liu Chunyu Xu Yecheng Yao Yenan Feng Zhili Li Bike Zhang Yang Song Peter Hao Yanping Zhang Hao Li Qun Li George F.Gao Guoqing Shi Wenbo Xu 2021China CDC weekly2021,3,41:13
3How we can improve patients’comfort after Milligan- Morgan open haemorrhoidectomy显示文摘AIM:To demonstrate the value of Diosmin(flavonidic fraction)in the management of post-haemorhoidectomic symptoms.METHODS:Eighty-six consecutive patients with grades ⅢandⅣacute mixed hemorrhoids admitted to the Anorectal Surgical Department of First Affiliated Hospital,Xinjiang Medical University from April 2009 to April 2010,were enrolled in this study.An observerblinded,randomized trial was conducted to compare post-haemorhoidectomic symptoms with use of Diosmin flavonidic fraction vs placebo.Eighty-six patients were randomly allocated to receive Diosmin flavonidic fraction 500 mg for 1 wk(n=43)or placebo(n=43).The Milligan-Morgan open haemorrhoidectomy was performed by a standardized diathermy excision method.Pain,bleeding,heaviness,pruritus,wound edema and mucosal discharge were observed after surgery.The postoperative symptoms and hospitalization time were recorded.RESULTS:The mean age of the Diosmin group and controls was 53.2 and 51.3 years,respectively.In Diosmin group,haemorrhoid piles were of the third degree in 33 patients and the fourth degree in 10;and in the control group,29 were of the third degree and 14 were of the fourth degree.There was no statistically significance in age,gender distribution,degree and number of excised haemorrhoid piles,and the mean duration of haemorrhoidal disease between the two groups.There was a statistically significant improvement in pain,heaviness,bleeding,pruritus from baseline to the 8th week after operation(P<0.05).Patients taking Diosmin had a shorter hospitalization stay after surgery(P< 0.05).There was also a significant improvement on the proctoscopic appearance(P<0.001).However,there was no statistical difference between the two groups in terms of wound mucosal discharge.Two patients experienced minor bleeding at the 8th week in Diosmin group,and underwent surgery.CONCLUSION:Diosmin is effective in alleviating postoperational symptoms of haemorrhoids.Therefore,it should be considered for the initial treatment after haemorrhoid surgery.However,further prospective randomized trials are needed to confirm the findings of this study.Ma-Mu-Ti-Jiang A ba-bai-ke-re Hong-Guo Huang Wen-Ni Re Kai Fan Hui Chu Er-Ha-Ti Ai Mai-Mai-Ti-Tu-Er-Xun KE Li-Mu Yi-Rui Wang Hao Wen 2011World Journal of Gastroenterology2011,17,11:13

5Source identification, contamination status and health risk assessment of heavy metals from road dusts in Dhaka, Bangladesh显示文摘In this study, concentrations of Cr, Mn, Ni, Cu, Zn, Cd and Pb were determined in road dusts collected from different locations in Dhaka to assess source, contamination status and health risk. Energy-dispersive X-ray fluorescence spectroscopy and energy-dispersive X-ray spectroscopy were used to determine Cr, Mn, Ni, Cu, Zn, Cd and Pb and their mean concentrations were 162.27 ± 29.46, 721.18 ± 180.14, 35.65 ± 12.55, 104.56 ± 128.33, 515.32 ± 321.90,BDL, and 342.82 ± 591.20 mg/kg, respectively. Among the heavy metals, highest concentrations of Cu, Zn and Pb were found at urban sites-7(municipal waste dumping) and 8(medical waste incineration). Highest concentration of Cr followed by Cu and Zn was found at site-5(Tejgaon, urban). Principal component analysis revealed that anthropogenic activities are the potential sources for Cr, Ni, Cu, Zn and Pb while earth crust for Mn. Pollution index and pollution load index results suggested that all the sites were contaminated and/or degraded by Cr, Cu, Zn and Pb except sites-9(urban), 10(sub-urban), 11(rural) while sites-7 and 8(urban) were extremely degraded. For noncarcinogenic health risk, hazard quotient values for dermal were higher compared to that of inhalation/ingestion. Though hazard index values were less than 1 at all the sites, these were at least one order of magnitude higher for children group than that of adult group, thus the children group may face more noncarcinogenic health risk at sites -7 and 8. Values of incremental lifetime cancer risk were from 10to 10showed no carcinogenic health risk by road dusts contaminated with the heavy metals.Aklima Nargis Ahsan Habib Md Nazrul Islam Kai Chen Md Shafiqul Islam Sarker A N M Al-Razee Wenbin Liu Guorui Liu Minggang Cai 2022Journal of Environmental Sciences2022,34,11:3
6Effectiveness of circumferential endoscopic mucosal resection with a novel tissue-anchoring device显示文摘AIM: To evaluate the efficacy of circumferential endoscopic mucosal resection (EMR) with a tissue-anchoring device in comparison to forceps precut EMR and conventional endoscopic submucosal dissection (ESD). METHODS: The study was designed as a prospective, randomized, ex vivo study. Fresh ex vivo specimens were harvested from adult white Yorkshire pigs weighing 30-50 kg. Seventy-five standardized, artificial lesions measuring 3 cm × 3 cm were created by methy- lene blue tattoo at the greater curvature in fresh ex vivo stomachs using the EASIE-R simulator platform (Endosim LLC, Berlin, MA, United States). The three advanced endoscopists performed the three resection techniques such as circumferential EMR using the tissue-anchoring device (TA-EMR), forceps precut EMR (FP-EMR), and endoscopic submucosal dissection. The endoscopists and the type of cutting methods were determined randomly by grouped randomized selection.The resection bed was grossly inspected to determine whether the lesion was resected 'en-bloc ' (defined as no remaining mucosal tattoo remaining on specimen). The resection bed was also probed for evidence of perforation. The procedural time of circumferential resection, submucosal dissection, and injection frequency were recorded by an independent observer.RESULTS: All 75 created lesions were successfully resected by three advanced endoscopists using the three techniques. The mean ± SD size of resected specimens (long axis) were 39.5 ± 5.6 mm, 36.5 ± 7.3 mm, and 44.6 ± 5.6 mm for TA-EMR, FP-EMR, and ESD respectively. The overall mean dissection time of both the TA- EMR and FP-EMR was significant shorter than ESD (TA- EMR: 5.1 ± 3.3 min, FP-EMR: 3.5 ± 2.0 min vs ESD: 15.8 ± 9.5 min, P < 0.001, P < 0.001). The overall mean total procedure time of both the tissue-anchoring and forceps circumferential EMR was significantly shorter than ESD (TA-EMR: 17.5 ± 6.0 min, FP-EMR: 16.6 ± 6.6 min vs ESD: 28.6 ± 13.9 min, P < 0.001, P < 0.001). The en-bloc resection rate of ESD was 100% (25/25) and the en-bloc resection rate of the TA-EMR (84.0%, 21/25) was higher than for the FP-EMR (60.0%, 15/25), yet not statistically significant (P = 0.18). The perforation rate of each technique was 8.0% (2/25). CONCLUSION: TA-EMR appears to be quicker than ESD, and there was a trend towards improved en bloc resection rate with the TA-EMR when compared to the FP-EMR.Yunho Jung Masayuki Kato Jongchan Lee Mark A Gromski Ram Chuttani Kai Matthes 2013World Journal of Gastrointestinal Endoscopy2013,5,6:3

17Genomic Surveillance for SARS-CoV-2 Variants of Concern from Imported COVID-19 Cases-the Mainland of China,2021显示文摘Introduction:After the epidemic in Wuhan City was brought under control in 2020,local outbreaks of coronavirus disease 2019(COVID-19)in the mainland of China were mainly due to imported COVID-19 cases.The ongoing evolution of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)has continued to generate new variants.Some have been designated as variants of concern(VOCs)by the World Health Organization(WHO).To better assess the role of imported SARS-CoV-2 surveillance and the prevalence of VOCs in 2021,the genomic surveillance data of SARS-CoV-2 from imported COVID-19 cases of 2021 in the mainland of China were analyzed.Methods:The analyses included the number of sequence submissions,time of sequence deposition,and time of detection of the VOCs in order to determine the timeliness and sensitivity of the surveillance.The proportions of VOCs were analyzed and compared with data from the Global Initiative of Sharing All Influenza Data(GISAID).Results:A total of 3,355 sequences of imported cases were submitted from 29 provincial-level administrative divisions,with differences in the number of sequence submissions and median time of sequence deposition.A total of 2,388 sequences with more than 90%genomic coverage were used for lineage analysis.The epidemic trend from Alpha to Delta to Omicron in imported cases was consistent with that in the GISAID.In addition,VOCs from imported cases were usually identified after WHO designation and before causing local outbreaks.Conclusions:The global distribution of SARSCoV-2 VOCs changed rapidly in 2021.Robust genomic surveillance of the imported SARS-CoV-2 in the mainland of China is of great significance.Severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),the etiological agent of coronavirus disease 2019(COVID-19),is constantly mutating under the different circumstances of global transmission(1).The emerging SARS-CoV-2 variants may have potential adverse impacts on epidemic traits and severity.To some extent,it is also capable of escaping natural and vaccine-induced immunity(2–3).Some of them were designated as variants of concern(VOCs)by the World Health Organization(WHO)(4).Therefore,robust surveillance is essential to assess the evolution of viruses in real time.After the epidemic in Wuhan City was brought under control in 2020,several COVID-19 outbreaks in the mainland of China have been proven to relate to SARS-CoV-2 contaminated cold-chain products(5–7),while most were caused by transmission through imported cases on flights,at isolation facilities,or in designated hospitals(8–9).Therefore,genomic surveillance for SARS-CoV-2 from imported cases is of great significance for monitoring the risk of different variants that were imported into the mainland of China,assessing the risk of importation-associated domestic spread,and helping guide public health interventions.On March 17,2020,the China CDC released a notice and launched genomic surveillance for SARS-CoV-2 from imported COVID-19 cases nationwide.The laboratories of provincial CDCs were required to conduct SARS-CoV-2 whole-genome sequencing for samples from imported cases and submit the genomic sequences to the China CDC in time.This study includes the analysis of genomic surveillance data of imported SARS-CoV-2 cases of 2021 from the mainland of China.Yenan Feng Xiang Zhao Zhixiao Chen Kai Nie Zeyuan Yin Ying Xia Ji Wang Peihua Niu Ruhan A Lili Li Dayan Wang Wenjie Tan Xuejun Ma Shiwen Wang Huanyu Wang George F.Gao Cao Chen Wenbo Xu 2022China CDC weekly2022,4,31:1
