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.

Objective:To explore the mechanism of long non-coding RNA nuclear-enriched transcript 1(LncRNA NEAT1)on improving myocardial injury in rats with myocardial infarction(MI)mechanism through miR-136/extracellular signal-regulated kinase 1/2(ERK1/2)axis.Methods:Using the random number table method,120 male SD rats were divided into 6 groups(n=20):sham group,myocardial infarction group(MI group),control interference group(sh-NC group),NEAT1 interference group(sh-NEAT1 group),NEAT1 interference+miR-136 control inhibition group(sh-NEAT1+antagomiR-NC group)and NEAT1 interference+miR-136 suppression group(sh-NEAT1+antagomiR-136 group).Seven days before MI operation,100 μl of corresponding adenovirus vector was injected into the myocardium.Rats in each group were ligated the left anterior descending vessel to establish MI model.In sham group,only the left chest was opened and the heart was exposed without ligation.H9C2 cardiomyocyte were divided into:control group,vehicle group,sh-NC group,sh-NEAT1 group,sh-NEAT1+antagomiR-NC group and sh-NEAT1+antagomiR-136 group.Car-diomyocyte were transfected with corresponding NEAT1 interference vector and negative control,miR-136 inhibitor and negative con-trol.StarBase prediction and dual luciferase report experiment verify the targeted regulation of LncRNA NEAT1 on miR-136;myocar-dial infarct size was measured by TTC staining,and myocardial histopathological changes were observed by HE staining;Echocardiog-raphy was used to detect rat cardiac function;detection of apoptosis in rat myocardial tissue and H9C2 cells by flow cytometry.ELISA method was used to detect serum oxidative stress,corresponding indexes of myocardial enzymes and the contents of inflammatory fac-tors in myocardial tissue and H9C2 cells.CCK8 and EdU staining were used to detect the proliferation ability of H9C2 cells.RT-qPCR was used to detect the expressions of miR-136,SIRT1 mRNA in myocardial tissue and H9C2 cells.Western blot was used to detect the expressions of ERK1/2,p-ERK1/2,B-cell lymphoma-2(Bcl-2),Bcl2-related X protein(Bax)protein in rat myocardial tissue and H9C2 cells.Results:The expression of LncRNA NEAT1 was up-regulated in injured myocardial tissues and cells,and the expression of miR-136 was down-regulated(P<0.05).At the same time,NEAT1 targets and regulates the level of miR-136.Inhibition of NEAT1 expression could increase left ventricular ejection fraction(LVEF),left ventricular fraction shortening(LVFS),Bcl-2 level,and de-crease the activities of creatine kinase(CK),lactate dehydrogenase(LDH),and aspartame Acid transaminase(AST),superoxide dismutase(SOD),reduce Bax,troponin Ⅰ(cTnⅠ),malondialdehyde(MDA),TNF-α,IL-1β,IL-6,ERK1/2/p-ERK1/2 levels(P<0.05),promote the proliferation of myocardial cells,inhibit cell apoptosis,reduce the area of myocardial infarction,inhibit oxida-tive stress and inflammation,and improve myocardial damage Inhibiting miR-136 can save the above effects.Conclusion:The expres-sion of LncRNA NEAT1 is up-regulated and the expression of miR-136 is down-regulated in injured myocardial tissue and cells.Inhibi-tion of LncRNA NEAT1 expression inhibits apoptosis,oxidative stress and inflammation through miR-136/ERK1/2 axis,thus improving myocardial injury.

Objective:To analyze the correlation between 24-hour urinary sodium excretion and early renal function impairment in patients with primary hypertension.Methods:This cross-sectional study included patients with primary hypertension who were admitted to the Department of Cardiology of the Chinese People′s Liberation Army General Hospital between January 2021 and October 2024. Patients were divided into low-sodium, medium-sodium, and high-sodium groups based on their 24-hour urinary sodium excretion. General clinical data were collected using the electronic medical record system. Urinary sodium, protein, and microalbumin excretion were analyzed from 24-hour urine samples. Spearman correlation analysis was used to explore the relationship between 24-hour urinary sodium excretion and urinary microalbumin excretion. A multiple linear regression model was used to further assess the independent association between these variables. Subgroup analyses were conducted based on age were performed to determine whether age influenced the relationship between urinary sodium excretion and renal function impairment.Results:A total of 1 065 patients with primary hypertension were included, with a mean age of (55.26±14.06) years, including 568(53.33%) males. The low-sodium, medium-sodium, and high-sodium groups included 223, 579, and 263 patients, respectively. The 24-hour urinary microalbumin excretion in the high-sodium group was significantly higher than in the medium-sodium and low-sodium groups, and this trend remained consistent across different age groups (all P<0.05). Spearman correlation analysis showed a positive correlation between 24-hour urinary sodium excretion and urinary microalbumin excretion ( r=0.220, P<0.001), and this relationship was observed in all age groups (all P<0.05). Multiple linear regression analysis confirmed an independent association between 24-hour urinary sodium excretion and urinary microalbumin excretion (all P<0.001), which persisted across different age groups (all P<0.05). Conclusion:In patients with primary hypertension, 24-hour urinary sodium excretion is closely associated with microalbumin excretion, suggesting a potential link to early renal function impairment.

Objective:To investigate the clinical characteristics of hip rotator-cuff tear, arthroscopic repair techniques, and short-term clinical efficacy.Methods:A retrospective analysis was performed on the patient cohort from our department who underwent arthroscopic repair for hip rotator-cuff tears from September 2019 to May 2021, with a minimum follow-up duration of two years. The sample included 17 subjects, composed of 6 males and 11 females, with a median age of 56 years (interquartile range 49.5-62.5). Notably, 9 patients (53%) reported nocturnal pain, and 10 patients (59%) exhibited a positive hip flexion resistance test. Patients' demographic details, clinical manifestations, radiographic findings, and intraoperative observations were analyzed. Pain amelioration was gauged by the visual analogue scale (VAS) at preoperative, 1 month, 3 months, and 6 months postoperative intervals. Enhancement in hip functionality was assessed by comparing the modified Harris hip score (mHHS), and the International hip outcome tool-12 (iHOT-12) at preoperative, 6 months, 12 months, and 24 months postoperative junctures.Results:All interventions were successfully completed, with an average surgical duration of 91.2±18.3 minutes. The follow-up period averaged 29 months. Every patient presented with a hip rotator-cuff tear, which was corrected using anchor suturing. 10 patients also had concomitant labrum injuries, with 5 cases undergoing labrum repair. The VAS score decreased from preoperative 5.24±1.15 to postoperative 2.29±0.69 at 1 month, 1.77±0.56 at 3 months, and 1.59±0.62 at 6 months ( F=79.31, P<0.001); The mHSS score increased from preoperative 49.59±6.11 to postoperative 81.00±3.89 at 6 months, 81.71±3.41 at 12 months, and 81.94±3.29 at 24 months ( F=232.00, P<0.001); The iHOT-12 score increased from preoperative 42.65±6.04 to postoperative 6 months 66.53±3.43, 12 months 68.12±3.48, and 24 months 69.06±3.53 ( F=150.00, P<0.001). Conclusion:Diagnosing hip rotator-cuff tears necessitates specific physical examinations complemented by high-definition magnetic resonance imaging. Arthroscopic surgery represents a potent treatment modality for hip rotator-cuff injuries, demonstrating substantial short-term clinical efficacy.

In recent years, with the advancement of technology, several kinds of slings have been put into clinical application and have achieved great outcomes. This article reviews the application of urethral sling in the treatment of SUI after prostatectomy.

Hepatolithiasis is a common biliary disease in China. Surgical treatment principles of hepatolithiasis include "removing lesions, cleaning stones, correcting strictures, recovering the drainage and preventing the recurrence". Laparoscopic techniques have been increasingly applied in surgical treatment of hepatolithiasis recently. Right posterior bile duct is a predilection site of hepatolithiasis. Due to its unique anatomy, right posterior lobectomy, right posterior bile duct lithotomy and plasty remain challenging under laparoscopy. Based on relevant literatures and clinical experiences, the authors explore the strategy of laparoscopic treatment right posterior bile duct hepatolithiasis, aiming to provide reference for surgical colleagues.
