Objective To compare the clinical efficacy of neuroendoscope-assisted evacuation and navigation-assisted puncture drainage in treating thalamic hemorrhage breaking into the ventricle. Methods A retrospective analysis was conducted on the clinical data of 93 patients with thalamic hemorrhage breaking into the ventricle at Taihe Hospital of Wannan Medical College between January 2022 and February 2024. The patients received neuroendoscope-assisted removal of thalamic hematoma combined with contralateral extraventricular drainage (n＝44, neuroendoscope group) and navigation-assisted thalamic hematoma puncture drainage combined with contralateral extraventricular drainage (n＝49, navigation group), respectively. The treatment efficacy, surgical situation, and prognosis between the two groups were compared. Results The neuroendoscope group had longer operation duration, more intraoperative blood loss, higher hospitalization costs than the navigation group (P＜0.05). The neuroendoscope group had higher hematoma clearance rate 3rd after surgery and shorter length of stay than the navigation group (P＜0.05). There was no significant difference in the incidence of intracranial infection after surgery between the two groups. The neuroendoscope group had higher Glasgow coma scale (GCS) score at 1 week after surgery and Glasgow outcome scale (GOS) score at 3 months after surgery (P＜0.01). Conclusions Compared with navigation-assisted puncture, neuroendoscope-assisted evacuation can improve the thalamic hemorrhage clearance rate, shorten the length of stay, and improve the prognosis of patients.

γδ T cells display unique developmental, distributional, and functional patterns and can rapidly respond to various insults and contribute to diverse diseases. Different subtypes of γδ T cells are produced in the thymus prior to their migration to peripheral tissues. γδ T cells are enriched in the liver and exhibit liver-specific features. Accumulating evidence reveals that γδ T cells play important roles in liver infection, non-alcoholic fatty liver disease, autoimmune hepatitis, liver fibrosis and cirrhosis, and liver cancer and regeneration. In this study, we review the properties of hepatic γδ T cells and summarize the roles of γδ T cells in liver diseases. We believe that determining the properties and functions of γδ T cells in liver diseases enhances our understanding of the pathogenesis of liver diseases and is useful for the design of novel γδ T cell-based therapeutic regimens for liver diseases.

Natural killer cells are the key effector cells in innate immune response,playing the role in pathogen clearance and tumor immunosurveillance by cytokine secretion and cytotoxicity.Hematopoietic stem cells go through developmental intermediates to generate mature NK cells under the progressive regulation of extrinsic factors and intrinsic factors.In the past thirty years, great progresses have been made in the developmental progress,niches,regulation of NK cells and the relationship between NK cells and dis-eases.In this review,we will discuss in detail the molecular mechanisms of NK cell development and the diseases caused by functional compromise of NK cells.

Objective To investigate analgesic effects of the selective blocking of descending facilitation targeting μ opioid receptor positive neurons in the rostral ventromedial medulla ( RVM) in a rat model of bone cancer pain. Methods Forty-eight adult female Wistar rats weighing 180-200 g were randomly divided into 6 groups: group Ⅰ control ( n = 3) ;group Ⅱ bone cancer pain induced by intra-tibia inoculation of Walker 256 mammary gland carcinoma cells ( n = 9) ;group Ⅲ-Ⅵ received a single intra-RVM micro-injection of PBS (group Ⅲ), dermorphin (group Ⅳ) , saporin (group Ⅴ) and dermorphin-saporin ( group Ⅵ) respectively at 28 days before intra-tibia inoculation ( n = 9 each) . Starting from 3 to 20 days after intra-tibia inoculation, mechanical allodynia was assessed and recorded. The animals were sacrificed on 7, 14 and 20 days after intra-tibia inoculation, after repetitive non-noxious tactile stimulation of the hindpaw. The total number of Fos-positive neurons in the spinal dorsal horn was measured as a marker indicative of central sensitization. Results The animals developed nociceptive hypersensitivity after intra-tibia cancer cell inoculation in group Ⅱ -Ⅵ . Nociceptive hypersensitivity was significantly decreased during 4-7 days after the onset of nociception in group Ⅵ (dermorphin-saporin). The number of Fos positive neurons in bilateral spinal dorsal horn was significantly increased by intra-tibia inoculation of cancer cells in group Ⅱ-Ⅵ as compared with control group and was significantly lower at day 14 and 20 after inoculation in group Ⅵ (dermorphin-saporin) than in group Ⅱ - Ⅴ.Conclusion Selective blocking of descending facilitation targeting μ opioid receptor positive neurons in RVM can effectively reduce nociceptive hypersensitivity induced by intra-tibia inoculation of Walker56 mammary gland carcinoma cells.
