| 1 | Atypical clinical and pathological findings in a patient with isolated cortical vein thrombosis显示文摘Isolated cortical vein thrombosis often produces a focal lesion. Because of the rapid development of collateral circulation, increased intracranial pressure has never been reported in a patient with isolated cortical vein thrombosis. The diagnosis of isolated cortical vein thrombosis is based mainly on MRI, catheter digital subtraction angiography, and histological findings, but may be challenging. We report a patient who presented with intermittent seizures and left-sided limb weakness. Her symptoms gradually progressed, and she eventually developed signs of increased intracranial pressure. Imaging studies showed a space-occupying lesion in the right frontal lobe of the brain. As we could not diagnose isolated cortical vein thrombosis based on the preoperative findings, surgical excision of the lesion was performed under general anesthesia. Histological examination showed destruction of the brain parenchyma with infiltration of macrophages, proliferation of reactive astrocytes and small vessels, and foci of hemorrhage. Further examination found that a number of small vessels in both the subarachnoid space and brain parenchyma were filled with thrombus, some of which was organized. Elastic fiber staining showed that the obstructed vessels were veins. We diagnosed isolated cortical vein thrombosis with atypical clinical features. | Yan Ding Vance Fredrickson Yicong Lin Yueshan Piao Xiangbo Wang Dehong Lu Cunjiang Li | 2012 | Neural Regeneration Research2012，7，31： | 3 |
| 2 | Medroxyprogestogen enhances apoptosis of SKOV-3 cells via inhibition of the PI3K/Akt signaling pathway显示文摘We sought to assess the effect of progestin on the apoptosis of epithelial ovarian cancer cell line SKOV-3 and via regulation of phosphorylation signaling in.Epithelial ovarian cancer cell line SKOV-3 was treated with medroxyprogestogen,phosphatidylinositol 3-kinase inhibitor LY294002 and vehicle control.Akt,phospho-Akt,Bcl-2 and phospho-Bad proteins were examined by immunoblotting assays.Medroxyprogestogen-induced apoptosis was assessed by MTT assays and Annexin V apoptosis assay.We found no significant difference in Akt and Bad expression in both the medroxyprogestogen groups and the control group.The levels of phospho-Akt,Bcl-2 and phospho-Bad were decreased in all the medroxyprogestogen groups and significantly decreased in the high dose mitogen-activated protein (MAP) group (10 μmol/L).Viability of SKOV-3 was reduced and apparent apoptosis of SKOV-3 cells was observed with increased doses of MAP.The findings suggest that medroxyprogestogen can induce SKOV-3 cell apoptosis by inhibiting Akt phosphorylation. | Yan Li Yi Jiang Yicong Wan Lin Zhang Weiwei Tang Jingjing Ma Shan Wu Wenjun Cheng | 2013 | The Journal of Biomedical Research2013，27，1： | 2 |
| 3 | Characterization of a Novel Weak Allele of RGA1/D1 and Its Potential Application in Rice Breeding显示文摘Semi-dwarfing improves the lodging resistance and yield of rice,and the vast majority of modern rice varieties harbor the sd1 allele to decrease plant height,resulting in reduced genetic diversity and negative agronomic traits.Thus,exploring alternative sources of dwarfism is imperative for rice breeding.Here,we identified a novel RGA1 allele,d1-w,from a local indica variety Xiaolixiang(XLX)using a map-based cloning approach.Compared with other rice varieties,RGA1 in XLX contained a unique single nucleotide polymorphism that resulted in an additional transcript and reduced functional RGA1 transcript level.The RGA1 from Nipponbare was introduced into XLX to estimate the value of d1-w in rice breeding.Compared with transgenic XLX plants(XLX^(D1)),XLX exhibited reduced plant height,increased stem strength,lower reactive oxygen species accumulation,delayed senescence,stronger photosynthesis,higher grain yield and quality(including external,milling and nutritional qualities),and enhanced resistance to drought and Rhizoctonia solani.Therefore,we proposed that the d1-w allele has potential as an excellent dwarfism resource for rice breeding. | LIU Yantong LI Ting JIANG Zhishu ZENG Chuihai HE Rong QIU Jiao LIN Xiaoli PENG Limei SONG Yongping ZHOU Dahu CAI Yicong ZHU Changlan FU Junru HE Haohua XU Jie | 2022 | Rice science2022，29，6： | 2 |
| 4 | Brain stimulation for epilepsy显示文摘Anumber of therapies have been developed in the past decades.About two thirds of patients can be seizure free with antiepileptic drugs.1 Other patients are drug resistant,some of whom are good candidates for epileptic focus resection and become seizure free after surgery.2 The treatment for drug-resistant patients who are not eligible for resection is still challenging.Traditionally,these patients can receive palliative surgery such as callosotomy and multiple subpial transection,3,4 but the long-term outcomes of these procedures are not satisfactory.5-7 In the past decades,neuromodulation techniques have been applied in the treatment of epilepsy.Much evidence has been accumulated about the therapeutic effects of vagus nerve stimulation for epilepsy.In contrast to peripheral nerve stimulation,brain stimulation techniques have also been developed for patients with epilepsy recently. | Wang Yuping | 2014 | Chinese Medical Journal2014，，18： | 1 |
| 5 | Co-delivery of TRAIL and paclitaxel by fibronectin-targeting liposomal nanodisk for effective lung melanoma metastasis treatment显示文摘Melanoma is a highly aggressive cancer which often forms metastatic tumors in the lung,leading to sharply reduced patients'survival rate.Effectively treating these tumors thus could improve late stage melanoma with lung metastasis.In this study,we fabricated a Cys-Arg-Glu-Lys-Ala with N-methylated Glu(CR(NMe)EKA)decorated disk shaped nano vehicle to co-deliver tumor necrosis factor-related apoptosis-inducing ligand(TRAIL)and paclitaxel(PTX)to lung melanoma tumor sites(TRAIL-[ND-PTX]^(CR(NMe)EKA)).These nanodisks displayed better tumor-targeting and penetration capability than spherical nanoparticles,while the fibronectin-targeting CR(NMe)EKA motif also increased the tumor accumulation of loaded drugs.The combined usage of TRAIL and PTX both killed tumor cells and reduced local nutrition supply,leading to stronger overall anti-tumor effect.This TRAIL-[ND-PTX]^(CR(NMe)EKA)system performed remarkably better than free paclitaxel and also significantly elongated survival rate of melanoma lung metastasis bearing mice,without displaying significant toxicity.Hence,this designing strategy and the fabricated nanoplatform possess potential for further development. | Shiqi Huang Lang Deng Hanming Zhang Luyao Wang Yicong Zhang Qing Lin Tao Gong Xun Sun Zhirong Zhang Ling Zhang | 2022 | Nano Research2022，15，1： | 1 |
| 6 | Dissecting PCNA function with a systematically designed mutant library in yeast显示文摘Proliferating cell nuclear antigen (PCNA), encoded by POL30 in Saccharomyces cerevisiae, is a key component of DNA metabolism. Here, a library consisting of 304 PCNA mutants was designed and constructed to probe the contribution of each residue to the biological function of PCNA. Five regions with elevated sen sitivity to DNA damaging reagents were identified using high-throughput phe no type screening. Using a series of genetic and biochemical analyses, we demonstrated that one particular mutant, K168A, has defects in the DNA damage tolerance (DDT) pathway by disrupting the interaction between PCNA and Rad5. Subsequent domain analysis showed that the PCNA-Rad5 interaction is a prerequisite for the function of Rad5 in DDT. Our study not only provides a resource in the form of a library of versatile mutants to study the functions of PCNA, but also reveals a key residue on PCNA (K168) which highlights the importance of the PCNA-Rad5 interaction in the template switching (TS) pathway. | Qingwen Jiang Weimin Zhang Chenghao Liu Yicong Lin Qingyu Wu Junbiao Dai | 2019 | Journal of Genetics and Genomics2019，46，6： | 0 |
