Objective To investigate the level of self-perceived burden(SPB) and analyze the influencing factors in continuous ambulatory peritoneal dialysis(CAPD) patients.Methods One hundred and ten CAPD patients were investigated by a self-designed demographic questionnaire and Self-Perceived Burden Scale (SPBS).Results The total score of SPBS was (30.27±7.88) points,being in a middle level,and 85.45％ of the patients showed different levels of burden.Single factor analysis showed the influencing factors of self-perceived burden were marital status,family per capita income,the main caregivers and selfcare ability.Conclusions Most CAPD patients have obvious self-perceived burden,nursing staff should use the relevant nursing measures to reduce the SPB with CAPD patients and improve their quality of life.

Long non-coding RNA (lncRNA) is defined as non-protein coding transcript longer than 200 nucleotides. In the form of RNA, it affects gene expression at the epigenetic, transcriptional and post-transcriptional levels, and is widely involved in the body's pathophysiological processes. This review summarizes the research progress of lncRNA in the field of parasitology in order to find new targets for the prevention and treatment of parasitic diseases.

Objective:To explore intraoperative assessment of blood supply to the femoral head after femoral neck fracture, and the correlation between the blood supply and postoperative osteonecrosis of the femoral head.Methods:A retrospective analysis was performed of the 63 patients with femoral neck fracture who had been treated at Department of Orthopaedic Trauma and Microsurgery, Zhongnan Hospital of Wuhan University by open reduction and internal fixation with hollow compression screws from April 2016 to March 2021. They were 39 males and 24 females with an age of (44.9±13.6) years. There were 42 cases of Garden type Ⅲ and 21 cases of Garden type Ⅳ. Time from injury to operation was (4.1±2.4) days. After internal fixation, a hole was drilled using a 2.0 mm Kirschner wire at 2.0 cm above the femoral head-neck junction to observe the velocity, color, and characteristics of the blood oozing at the drill hole. The patients were divided into a good oozing group of 51 cases in whom bright red blood oozing was observed within 15 seconds after drilling and a poor oozing group of 12 cases in whom dark red blood oozing was observed beyond 15 seconds after drilling. The incidence of postoperative femoral head necrosis, Harris hip score, and visual analogue scale (VAS) for pain were compared between the 2 groups. Single factor and multi factor analyses were conducted using the Cox regression model to analyze the factors influencing postoperative femoral head necrosis in the patients.Results:The 63 patients were followed up for 24 (18, 36) months. The 2 groups were comparable because there was no significant difference in the preoperative general data between them ( P>0.05). Femoral head necrosis was observed in 3 cases in the good oozing group and in 5 cases in the poor oozing group, showing a significant difference between the 2 groups ( P<0.05). The Harris hip score [90.0 (86.0, 92.0)] and the VAS pain score [1.0 (1.0, 2.0)] at 1 year after surgery in the good oozing group were significantly better than those in the poor oozing group [85.5 (71.3, 88.8) and 2.5 (1.0, 3.8)] ( P<0.05). Multivariate Cox regression analysis showed that Garden type Ⅳ ( HR=6.784, 95% CI: 1.324 to 35.664, P=0.023) and intraoperative poor blood oozing ( HR=10.744, 95% CI: 2.359 to 51.774, P=0.003) were risk factors for femoral head necrosis after cannulated compression screw fixation of fractures of displaced femoral neck ( P<0.05). Conclusions:The blood supply to the femoral head after femoral neck fracture can be directly assessed by drilling a hole in the femoral head after open reduction and internal fixation. Intraoperative poor blood oozing is a risk factor for the femoral head necrosis after cannulated compression screw fixation of fractures of displaced femoral neck.

The gut microbiota plays a pivotal role in the immunomodulatory and protumorigenic microenviron-ment of colorectal cancer(CRC).However,the effect of ginsenoside Rk3(Rk3)on CRC and gut microbiota remains unclear.Therefore,the purpose of this study is to explore the potential effect of Rk3 on CRC from the perspective of gut microbiota and immune regulation.Our results reveal that treatment with Rk3 significantly suppresses the formation of colon tumors,repairs intestinal barrier damage,and regulates the gut microbiota imbalance caused by CRC,including enrichment of probiotics such as Akkermansia muciniphila and Barnesiella intestinihominis,and clearance of pathogenic Desulfovibrio.Subsequent metabolomics data demonstrate that Rk3 can modulate the metabolism of amino acids and bile acids,particularly by upregulating glutamine,which has the potential to regulate the immune response.Furthermore,we elucidate the regulatory effects of Rk3 on chemokines and inflammatory factors associated with group 3 innate lymphoid cells(ILC3s)and T helper 17(Th17)signaling pathways,which inhibits the hyperactivation of the Janus kinase-signal transducer and activator of transcription 3(JAK-STAT3)signaling pathway.These results indicate that Rk3 modulates gut microbiota,regulates ILC3s immune response,and inhibits the JAK-STAT3 signaling pathway to suppress the development of colon tumors.More importantly,the results of fecal microbiota transplantation suggest that the inhibitory effect of Rk3 on colon tumors and its regulation of ILC3 immune responses are mediated by the gut microbiota.In summary,these findings emphasize that Rk3 can be utilized as a regulator of the gut microbiota for the prevention and treatment of CRC.

Objective:To analyze the clinical characteristics, treatment, and prognosis of ectopic bronchogenic cysts in children.Methods:A retrospective analysis was conducted on the data including the clinical characteristics, auxiliary examination and treatment of 21 children with ectopic bronchogenic cysts diagnosed pathologically at Children′s Hospital Affiliated to Zhengzhou University from July 2015 to December 2023. There were 16 males and 5 females, with a male-female ratio of 3.2∶1, and the age ranged from 4 days to 8 years old (median age 2 years and 8 months).Results:Among the 21 cases of ectopic bronchogenic cysts, 11 cases were found in the pharynx, with symptoms including dyspnea (4 cases), snoring during sleep (3 cases), and choking on milk(4 cases).Ten cases were found in the head, neck or anterior chest, 5 of these cases had infection history, and 5 showed progressive mass growth.Imaging and endoscopy showed 9 patients underwent preoperative color ultrasonography revealed cystic masses with well-defined boundaries. CT examination was performed on 13 patients, which showed round or nearly round masses with homogeneous density, smooth margins, and regular cyst walls. CT attenuation values ranged from 2 to 52 Hounsfield Units (HU). Four cystic lesions were assessed via MRI, 3 cases demonstrated long T1 and long T2 signals, while 1 case had a slight short T1 and long T2 signal, with high signal intensity on fat-suppressed images. Eleven cases of pharyngopharyngeal cysts were examined by electronic nasopharyngoscopy. The cysts appeared as spherical or ovoid masses with smooth surfaces, close to or slightly light in color with the surrounding tissue, with one cyst presenting with a bluish blue in the oropharynx. All 11 pharyngeal cysts were excised using low-temperature plasma under general anesthesia and intubation assisted by a nasal endoscope. The cysts were pulled and excised as completely as possible.Ten cases of neck and anterior chest cysts were completely excised. Postoperative histopathology confirmed bronchogenic cyst. Twenty-one children were followed up postoperatively for 4 months to 7 years without recurrence, except for 1 patient who was lost to follow-up.Conclusions:Ectopic bronchogenic cysts are uncommon and lack of typical imaging and clinical features.Combination of ultrasonography, CT and MRI is recommended for cases occuered in neck and anterior chest, while electronic nasopharyngoscopy complements pharyngeal evaluations. Surgical intervention is the preferred treatment choice for this disease.
