1DIAGNOSIS AND TREATMENT OF CESAREAN SCAR PREGNANCY显示文摘Objective To investigate the early diagnosis and treatment of cesarean scar pregnancy(CSP).Methods Clinical data of 28 patients with CSP in Peking Union Medical College Hospital from January 1994 to April 2007,including age,interval from the last cesarean delivery to diagnosis,clinical presentation,location of the lesion,process of diagnosis and treatment,outcome,and follow-up,were retrospectively analyzed.Results CSP constituted 1.05% of all ectopic pregnancies,and the ratio of CSP to pregnancy was 1∶1221.The mean age of the group was 31.4 years.Twenty-six women had only one prior cesarean delivery.The interval from the last cesarean delivery to diagnosis ranged from 4 months to 15 years.The most common presenting symptoms of CSP were amenorrhoea and vaginal bleeding.Seventeen cases were misdiagnosed as early intrauterine pregnancies and 2 were misdiagnosed as gestational trophoblastic tumor.The other 9 were diagnosed definitely before treatment.The diagnosis was made based on cesarean delivery history,gynecologic examination,ultrasound,and magnetic resonance imaging(MRI).The treatment of CSP included systemic or local methotrexate administration,conservative surgery,and hysterectomy.The conservative treatment was successful in 24 cases.All of the 28 women were cured through individual therapies.Conclusions CSP is rare and usually misdiagnosed as other diseases.Ultrasound is valuable for diagnosing CSP,and MRI can be used as an adjunct to ultrasound scan.Early diagnosis offers the options of conservative treatment and greatly improves the outcome of patients.Individual therapy is strongly recommended.Lan-zhou Jiao Jun Zhao Xi-run Wan Xin-yan Liu Feng-zhi Feng Tong Ren Yang Xiang 2008Chinese Medical Sciences Journal2008,23,1:65
2Erianin,a novel dibenzyl compound in Dendrobium extract,inhibits lung cancer cell growth and migration via calcium/calmodulin-dependent ferroptosis显示文摘Ferroptosis,a novel form of programmed cell death,is characterized by iron-dependent lipid peroxidation and has been shown to be involved in multiple diseases,including cancer.Stimulating ferroptosis in cancer cells may be a potential strategy for cancer therapy.Therefore,ferroptosis-inducing drugs are attracting more attention for cancer treatment.Here,we showed that erianin,a natural product isolated from Dendrobium chrysotoxum Lindl,exerted its anticancer activity by inducing cell death and inhibiting cell migration in lung cancer cells.Subsequently,we demonstrated for the first time that erianin induced ferroptotic cell death in lung cancer cells,which was accompanied by ROS accumulation,lipid peroxidation,and GSH depletion.The ferroptosis inhibitors Fer-1 and Lip-1 but not Z-VAD-FMK,CQ,or necrostatin-1 rescued erianin-induced cell death,indicating that ferroptosis contributed to erianin-induced cell death.Furthermore,we demonstrated that Ca^(2+)/CaM signaling was a critical mediator of erianin-induced ferroptosis and that blockade of this signaling significantly rescued cell death induced by erianin treatment by suppressing ferroptosis.Taken together,our data suggest that the natural product erianin exerts its anticancer effects by inducing Ca^(2+)/CaMdependent ferroptosis and inhibiting cell migration,and erianin will hopefully serve as a prospective compound for lung cancer treatment.Peng Chen Qibiao Wu Jiao Feng Lili Yan Yitian Sun Shuiping Liu Yu Xiang Mingming Zhang Ting Pan Xiaying Chen Ting Duan Lijuan Zhai Bingtao Zhai Wengang Wang Ruonan Zhang Bi Chen Xuemeng Han Yicong Li Liuxi Chen Ying Liu Xingxing Huang Ting Jin Wenzheng Zhang Hong Luo Xiaohui Chen Yongqiang Li Qiujie Li Guohua Li Qin Zhang Lvjia Zhuo Zuyi Yang Huifen Tang Tian Xie Xiaoping Ouyang Xinbing Sui 2020Signal Transduction and Targeted Therapy2020,5,1:42

7Expert consensus on the use of human serum albumin in critically ill patients显示文摘Introduction Human serum albumin(HSA)is a non-glycosylated,negatively charged,single-chain polypeptide composed of 585 amino acid residues with a relative molecular mass of 66.438 kD.It is synthesized by the liver at a rate of approximately 200 mg·kg^(-1)·day^(-1),with a half-life of 21 days,and subjected to catabolism in the muscles,liver,and kidneys at a rate of 4%per day.[1]Albumin,accounting for 60%of the total plasma protein,has various physiological functions,[2]such as maintaining 70%to 80%of effective plasma colloid osmotic pressure,coordinating vascular endothelial integrity,anti-oxidant and anti-inflammatory activities,maintaining the acidbase balance,and participating in the transport,distribution,and metabolism of a variety of endogenous and exogenous substances.Yue-Tian Yu Jiao Liu Bo Hu Rui-Lan Wang Xiang-Hong Yang Xiu-Ling Shang Gang Wang Chang-Song Wang Bai-Ling Li Ye Gong Sheng Zhang Xin Li Lu Wang Min Shao Mei Meng Feng Zhu You Shang Qiang-Hong Xu Zhi-Xiong Wu De-Chang Chen 2021Chinese Medical Journal2021,,14:22
8Baicalin induces ferroptosis in bladder cancer cells by downregulating FTH1显示文摘Ferroptosis is a non-apoptotic regulated cell death caused by iron accumulation and subsequent lipid peroxidation.Currently,the therapeutic role of ferroptosis on cancer is gaining increasing interest.Baicalin an active component in Scutellaria baicalensis Georgi with anticancer potential various cancer types;however,the effects of baicalein on bladder cancer and the underlying molecular mechanisms remain largely unknown.In the study,we investigated the effect of baicalin on bladder cancer cells5637 and KU-19-19.As a result,we show baicalin exerted its anticancer activity by inducing apoptosis and cell death in bladder cancer cells.Subsequently,we for the first time demonstrate baicalin-induced ferroptotic cell death in vitro and in vivo,accompanied by reactive oxygen species(ROS) accumulation and intracellular chelate iron enrichment.The ferroptosis inhibitor deferoxamine but not necrostatin-1,chloroquine(CQ),N-acetyl-L-cysteine,L-glutathione reduced,or carbobenzoxy-valyl-alanyl-aspartyl-[O-methyl]-fluoromethylketone(Z-VAD-FMK) rescued baicalin-induced cell death,indicating ferroptosis contributed to baicalin-induced cell death.Mechanistically,we show that ferritin heavy chain1(FTH1) was a key determinant for baicalin-induced ferroptosis.Overexpression of FTH1 abrogated the anticancer effects of baicalin in both 5637 and KU19-19 cells.Taken together,our data for the first time suggest that the natural product baicalin exerts its anticancer activity by inducing FTH1-dependent ferroptosis,which will hopefully provide a prospective compound for bladder cancer treatment.Na Kong Xiaying Chen Jiao Feng Ting Duan Shuiping Liu Xueni Sun Peng Chen Ting Pan Lili Yan Ting Jin Yu Xiang Quan Gao Chengyong Wen Weirui Ma Wencheng Liu Mingming Zhang Zuyi Yang Wengang Wang Ruonan Zhang Bi Chen Tian Xie Xinbing Sui Wei Tao 2021Acta Pharmaceutica Sinica B2021,11,12:23

10Lung transplantation as therapeutic option in acute respiratory distress syndrome for coronavirus disease 2019-related pulmonary fibrosis显示文摘Background:Critical patients with the coronavirus disease 2019(COVID-19),even those whose nucleic acid test results had turned negative and those receiving maximal medical support,have been noted to progress to irreversible fatal respiratory failure.Lung transplantation(LT)as the sole therapy for end-stage pulmonary fibrosis related to acute respiratory distress syndrome has been considered as the ultimate rescue therapy for these patients.Methods:From February 10 to March 10,2020,three male patients were urgently assessed and listed for transplantation.After conducting a full ethical review and after obtaining assent from the family of the patients,we performed three LT procedures for COVID-19 patients with illness durations of more than one month and extremely high sequential organ failure assessment scores.Results:Two of the three recipients survived post-LT and started participating in a rehabilitation program.Pearls of the LT team collaboration and perioperative logistics were summarized and continually improved.The pathological results of the explanted lungs were concordant with the critical clinical manifestation,and provided insight towards better understanding of the disease.Government health affair systems,virology detection tools,and modern communication technology all play key roles towards the survival of the patients and their rehabilitation.Conclusions:LT can be performed in end-stage patients with respiratory failure due to COVID-19-related pulmonary fibrosis.If confirmed positive-turned-negative virology status without organ dysfunction that could contraindicate LT,LT provided the final option for these patients to avoid certain death,with proper protection of transplant surgeons and medical staffs.By ensuring instant seamless care for both patients and medical teams,the goal of reducing the mortality rate and salvaging the lives of patients with COVID-19 can be attained.Jing-Yu Chen Kun Qiao Feng Liu Bo Wu Xin Xu Guo-Qing Jiao Rong-Guo Lu Hui-Xing Li Jin Zhao Jian Huang Yi Yang Xiao-Jie Lu Jia-Shu Li Shu-Yun Jiang Da-Peng Wang Chun-Xiao Hu Gui-Long Wang Dong-Xiao Huang Guo-Hui Jiao Dong Wei Shu-Gao Ye Jian-An Huang Li Zhou Xiao-Qin Zhang Jian-Xing He 2020Chinese Medical Journal2020,,12:19
11Evaluation of hyperreflective foci as a prognostic factor of visual outcome in retinal vein occlusion显示文摘AIM:To evaluate the potential role of hyperreflective foci(HF) as a prognostic indicator of visual outcome in patients with macular edema(ME) due to retinal vein occlusion(RVO).METHODS:We retrospectively reviewed 50 eyes of 50 patients with ME due to ischemic central retinal vein occlusion(CRVO),non-ischemic CRVO and branch retinal vein occlusion(BRVO) who were treated with anti-vascular endothelial growth factor(anti-VEGF) at Beijing Tongren Eye Center from January 2013 to July 2016.All patients underwent best-corrected visual acuity(BCVA),spectral domain optical coherence tomography(SD-OCT) at baseline and follow-up.Such factors were evaluated and compared among three groups as baseline and final BCVA,central retinal thickness(CRT),external limiting membrane(ELM) status and the numbers of HF in different position.Multiple linear regression analysis was employed to analyze the relationship between baseline HF and final BCVA.Changes of HF before and after treatment were evaluated too.RESULTS:Among three groups,HF could be located in each retinal layers,as well as in vitreous cavity.The mean HF in outer retinal layer(ORL) at baseline was 5.29±8.48 in ischemic CRVO with intact ELM,1.93±2.76 in non-ischemic CRVO,and 1.75±2.05 in BRVO.With disrupted ELM,the mean HF in ORL increased.There was statistically difference of HF in ORL between intact and disrupted ELM.The numbers of HF in ORL were associated with poor visual outcome among three groups.However,HF in inner retinal layer(IRL) and vitreous cavity were not associated with poor visual outcome.Meanwhile,the baseline HF in ORL and vitreous cavity reduced significantly in nonischemic CRVO and BRVO after anti-VEGF treatment.CONCLUSION:The numbers of HF in ORL are prognostic factors associated with the final BCVA in patients with ME due to RVO after anti-VEGF treatment.Bin Mo Hai-Ying Zhou Xuan Jiao Feng Zhang 2017International Journal of Ophthalmology(English edition)2017,10,4:15
12Neuroprotective Autophagic Flux Induced by Hyperbaric Oxygen Preconditioning is Mediated by Cystatin C显示文摘We have previously reported that Cystatin C(CysC) is a pivotal mediator in the neuroprotection induced by hyperbaric oxygen(HBO) preconditioning; however,the underlying mechanism and how CysC changes after stroke are not clear. In the present study, we demonstrated that CysC expression was elevated as early as 3 h after reperfusion, and this was further enhanced by HBO preconditioning. Concurrently, LC3-II and Beclin-1, two positive-markers for autophagy induction, exhibited increases similar to CysC, while knockdown of CysC blocked these elevations. As a marker of autophagy inhibition, p62 was downregulated by HBO preconditioning and this was blocked by CysC knockdown. Besides, the beneficial effects of preserving lysosomal membrane integrity and enhancing autolysosome formation induced by HBO preconditioning were abolished in CysC-/-rats.Furthermore, we demonstrated that exogenous CysC reduced the neurological deficits and infarct volume after brain ischemic injury, while 3-methyladenine partially reversed this neuroprotection. In the present study, we showed that CysC is biochemically and morphologically essential for promoting autophagic flux, and highlighted the translational potential of HBO preconditioning and CysC for stroke treatment.Zongping Fang Yun Feng Yuheng Li Jiao Deng Huang Nie Qianzhi Yang Shiquan Wang Hailong Dong Lize Xiong 2019Neuroscience Bulletin2019,35,2:14

14Association of KIR Genotypes and Haplotypes with Susceptibility to Chronic Hepatitis B Virus Infection in Chinese Han Population显示文摘Killer immunoglobulin-like receptor (KIR) genes can regulate the activation of NK and T cells upon interaction with HLA class I molecules. Hepatitis B virus (HBV) infection has been regarded as a multi-factorial disorder disease. Previous studies revealed that KIRs were involved in HCV and HIV infection or clearance. The aim of this study was to explore the possibility of the inheritance of KIR genotypes and haplotypes as a candidate for susceptibility to persistent HBV infection or HBV clearance. The sequence specific primer polymerase chain reaction (SSP-PCR) was employed to identify the KIR genes and pseudogenes in 150 chronic hepatitis B (CHB) patients, 251 spontaneously recovered (SR) controls, and 412 healthy controls. The frequencies of genotype G, M, FZ1 increased in CHB patients compared with healthy control subjects. The frequency of genotype AH was higher in SR controls than that in both CHB patients and healthy controls. The carriage frequencies of genotype G and AH were higher; while, the frequencies of AF and AJ were lower in SR controls than those in healthy control subjects. The frequency of A haplotype was lower, whereas, the frequency of B haplotype was higher in CHB patients and SR controls than those in healthy controls. In healthy controls, haplotype 4 was found lower compared with that in CHB patients and SR controls and the frequency of haplotype 5 was higher in SR controls than that in other two groups. Based on these findings, it seems that the genotypes M and FZ1 are HBV susceptive genotypes; AH, on the other hand, may be protective genotypes that facilitate the clearance of HBV. It appears that the haplotype 4 is HBV susceptive haplotype, whereas, haplotype 5 may be the protective haplotype that facilitates the clearance of HBV.Zhiming Lu Bingchang Zhang Shijun Chen Zhongtao Gai Zhaolei Feng Xiangdong Liu Yiqing Liu Xin Wen Li Li Yulian Jiao Chunyan Ma Song Shao Xiangfa Cui Guojian Chen Jianfeng Li Yneran Zhao 2008Cellular & Molecular Immunology2008,5,6:13

16Management of granulomatous lobular mastitis: an international multidisciplinary consensus(2021 edition)显示文摘Granulomatous lobular mastitis(GLM) is a rare and chronic benign inflammatory disease of the breast. Difficulties exist in the management of GLM for many front-line surgeons and medical specialists who care for patients with inflammatory disorders of the breast. This consensus is summarized to establish evidence-based recommendations for the management of GLM. Literature was reviewed using PubMed from January 1, 1971 to July 31, 2020. Sixty-six international experienced multidisciplinary experts from 11 countries or regions were invited to review the evidence.Levels of evidence were determined using the American College of Physicians grading system, and recommendations were discussed until consensus. Experts discussed and concluded 30 recommendations on historical definitions,etiology and predisposing factors, diagnosis criteria, treatment, clinical stages, relapse and recurrence of GLM. GLM was recommended as a widely accepted definition. In addition, this consensus introduced a new clinical stages and management algorithm for GLM to provide individual treatment strategies. In conclusion, diagnosis of GLM depends on a combination of history, clinical manifestations, imaging examinations, laboratory examinations and pathology.The approach to treatment of GLM should be applied according to the different clinical stage of GLM. This evidencebased consensus would be valuable to assist front-line surgeons and medical specialists in the optimal management of GLM.Qian-Qian Yuan Shu-Yuan Xiao Omar Farouk Yu-Tang Du Fereshte Sheybani Qing Ting Tan Sami Akbulut Kenan Cetin Afsaneh Alikhassi Rami Jalal Yaghan Irmak Durur-Subasi Fatih Altintoprak Tae Ik Eom Fatih Alper Mustafa Hasbahceci David Martínez-Ramos Pelin Seher Oztekin Ava Kwong Cedric W.Pluguez-Turul Kirstyn EBrownson Shirish Chandanwale Mehran Habib Liu-Yi Lan Rui Zhou Xian-Tao Zeng Jiao Bai Jun-Wen Bai Qiong-Rong Chen Xing Chen Xiao-Ming Zha Wen-Jie Dai Zhi-Jun Dai Qin-Yu Feng Qing-Jun Gao Run-Fang Gao Bao-San Han Jin-Xuan Hou Wei Hou Hai-Ying Liao Hong Luo Zheng-Ren Liu Jing-Hua Lu Bin Luo Xiao-Peng Ma Jun Qian Jian-Yong Qin Wei Wei Gang Wei Li-Ying Xu Hui-Chao Xue Hua-Wei Yang Wei-Ge Yang Chao-Jie Zhang Fan Zhang Guan-Xin Zhang Shao-Kun Zhang Shu-Qun Zhang Ye-Qiang Zhang Yue-Peng Zhang Sheng-Chu Zhang Dai-Wei Zhao Xiang-Min Zheng Le-Wei Zheng Gao-Ran Xu Wen-Bo Zhou Gao-Song Wu 2022Military Medical Research2022,9,4:13

20Editing of Rice Isoamylase Gene ISA1 Provides Insights into Its Function in Starch Formation显示文摘Isoamylase 1(ISA1) is an isoamylase-type debranching enzyme which plays a predominant role in amylopectin synthesis. In this study, the clustered regularly interspaced short palindromic repeats(CRISPR)/CRISPR-associated endonuclease 9(CRISPR/Cas9) system was used to edit ISA1 gene in rice via Agrobacterium-mediated transformation. We identified 36 genetic edited lines from 55 T_0 transgenic events, and classified the mutation forms into 7 types. Of those, two homozygous mutants, cr-isa1-1(type 1, with an adenine insertion) and cr-isa1-2(type 3, with a cytosine deletion) were selected for further analysis. Seed sizes of both cr-isa1-1 and cr-isa1-2 were affected, and the two mutants also displayed a shrunken endosperm with significantly lower grain weight. Electron microscopy analysis showed that abnormal starch granules and amyloplasts were found in cr-isa1-1 and cr-isa1-2 endosperm cells. The contents of total starch, amylose and amylopectin in the endosperm of the cr-isa1 mutants were significantly reduced, whereas sugar content and starch gel consistency were observably increased compared to the wild-type. The gelatinization temperature and starch chain length distributions of the cr-isa1 mutants were also altered. Moreover, transcript levels of most starch synthesis-related genes were significantly lower in cr-isa1 mutants. In conclusion, the results indicated that gene edition of ISA1 affected starch synthesis and endosperm development, and brought potential implications for rice quality breeding.CHAO Shufen CAI Yicong FENG Baobing JIAO Guiai SHENG Zhonghua LUO Ju TANG Shaoqing WANG Jianlong HU Peisong WEI Xiangjin 2019Rice science2019,26,2:10
