The Janus kinase/signal transducers and activators of transcription (JAK-STAT) control natural killer (NK) cells development and cytotoxic functions, however, whether long non-coding RNAs (lncRNAs) are involved in this pathway remains unknown. We found that miR155HG was elevated in activated NK cells and promoted their proliferation and effector functions in both NK92 and induced-pluripotent stem cells (iPSCs)-derived NK (iPSC-NK) cells, without reliance on its derived miR-155 and micropeptide P155. Mechanistically, miR155HG bound to miR-6756 and relieved its repression of JAK3 expression, thereby promoting the JAK-STAT pathway and enhancing NK cell proliferation and function. Further investigations disclosed that upon cytokine stimulation, STAT3 directly interacts with miR155HG promoter and induces miR155HG transcription. Collectively, we identify a miR155HG-mediated positive feedback loop of the JAK-STAT signaling. Our study will also provide a power target regarding miR155HG for improving NK cell generation and effector function in the field of NK cell adoptive transfer therapy against cancer, especially iPSC-derived NK cells.

A 19-year-old male patient with a history of congenital left oval window defect has had recurrent admissions to a children’s hospital for bacterial meningitis since the age of 7. Investigations revealed a left-sided type 1 incomplete partition deformity of the left ear with a congenital oval window defect, leading to communication between the cranium and the middle ear. The patient underwent a left canal wall down mastoidectomy and oval window defect repair, remaining well for 3 years. He experienced two more episodes of bacterial meningitis as he got older, prompting repeated exploratory tympanotomy and repair of the cerebrospinal fluid (CSF) leak after each episode. Recently, he was referred again for recurrent meningitis. Investigations showed a recurrent oval window defect. After undergoing left external ear canal transection, mastoid and middle ear obliteration, and left Eustachian tube obliteration, he remained well without further leaks or meningitis. Congenital oval window defect is rare and may present with recurrent bacterial meningitis secondary to spontaneous CSF leak via the oval window. Radiology plays a crucial role in identifying the source of the CSF leak, facilitating more precise preoperative counseling and surgical intervention.

Medical experts across different dynasties have interpreted the phrase"heavy abdomen as if carrying a load of five thousand coins,"found in the Synopsis of Golden Chamber,in various ways.The primary viewpoint is that the phrase uses exaggerated rhetoric to vividly describe the clinical characteristics of abdominal or low back heaviness in patients with kidney stagnation.However,why ZHANG Zhongjing used"money"as a metaphor,what specific type of coins"money"referred to,why the quantity"five thousand"was selected,and whether this description focused more on the weight or the shape,have not been further discussed by the academic community.This article systematically answers these questions based on the history of the development of ancient Chinese coins,the versions of the Synopsis of the Golden Chamber,and its annotations.Using the metaphor of"five thousand coins"for feeling heavy in the abdomen originates from the ancient people′s general understanding of money.The money in"five thousand coins"specifically refers to the wu zhu qian of the Han Dynasty,and the amount of"five thousand coins"is the savings of common people′s families at that time,and has universal reference significance."Five thousand coins"emphasizes the weight of"five thousand coins"rather than its shape.This study provides a novel perspective and theoretical basis for understanding the original text of the Synopsis of Golden Chamber.

Objective To analyze the thickness of cornea and corneal epithelium in healthy subjects by optical coherence tomography angiography (OCTA).Methods Totally 100 healthy subjects aged between 20 and 30 years were analyzed by OCTA technique.Using AngioVue OCTA system of retinal imaging mode,and using SSADA algorithm for imaging,the cornea and the corneal epithelium in the central corneal diameter range of 9 mm were measured.The differences of corneal and corneal epithelial thickness in different gender regions were compared.Results In the male and female group,the corneal central total thickness were (559.92 ±33.26) μm and(540.06 ±31.63)μm,and the corneal epithelial thickness were(57.78 ±4.88) μm and(56.88 ±4.57) μm,The total central corneal thickness and central corneal epithelial thickness of the male were greater than those of the female,the difference was statistically significant (t =3.06,2.10;all P < 0.05).The cornea of male was the thickest at S5,S7 and SN9,there were significant differences at S5 and S7 compared with female (t =2.93,2.83;all P < 0.05);The female cornea was the thickest at S5,SN7 and SN9,and the difference was significant at S5 compared with male.The cornea of male subjects was the thinnest at IT,which was statistically significant only at IT5 compared with female subjects in the same area (t =2.02,P < 0.05);The cornea of female subjects was the thinnest at T5,IT7 and T9,which was statistically significant only at T5 and T9 compared with male subjects in the same region (t =2.63,2.20;all P < 0.05);There was significant difference in corneal thickness between male and female at ST (t =3.1 1,2.79,2.33;all P < 0.05).The corneal epithelium was the thickest at IT5,I7,and I9,and the lowest at S5,S7 and S9,and there was no significant difference compared with female in the same region (all P > 0.05).The corneal epithelium of female at the IT5,T7,N9 were the thickest,SN5,S7,S9 were the thinnest;Except for M2 and SN5,there was no significant differences in corneal epithelium between male and female groups (all P > 0.05).Corneal central epithelium accounted for the largest percentage of total corneal thickness,and gradually decreased from inside to outside.Conclusion OCTA can be used to measure the thickness of corneal and corneal epithelial regions.
