Objective:To evaluate the effects of a reduced-positioning restrictions nursing program on postoperative recovery, sleep quality, self-care ability, and hip joint function in patients undergoing total hip arthroplasty (THA), providing a reference for postoperative positioning management.Methods:A randomized controlled trial was conducted, and 140 THA patients admitted to Zhejiang Provincial People′s Hospital from January 2022 to June 2023 were selected using convenience sampling. They were divided into a control group (70 cases) and an observation group (70 cases) using a random number table. The control group received conventional rehabilitation care, while the observation group received a reduced-positioning restrictions nursing program in addition to the conventional care. The incidence of dislocation at 3 months postoperatively, the activities of daily living, the hip joint function recovery at 1 month and 3 months postoperatively, the sleep quality at 1 month postoperatively were compared between the two groups.Results:Finally 63 cases in the control group and 64 cases in the observation group completed the study. The control group included 25 males and 38 females, with an average age of (65.44 ± 10.97) years, while the observation group included 28 males and 36 females, with an average age of (65.13 ± 12.18) years. At 3 months postoperatively, there was no significant difference in the dislocation rate between the control group and the observation group ( P>0.05). At 1 month and 3 months postoperatively, the scores of activities of daily living in the observation group were (77.89 ± 6.71) and (93.52 ± 6.59) points respectively, which were higher than those in the control group [(69.68 ± 5.53) and (87.38 ± 7.72) points], the differences were statistically significant ( t=5.38, 6.96, both P<0.05), the time, interaction and inter-group effects were all statistically significant ( F=33.93, 10.81, 876.91, all P<0.05). At 1 month postoperatively, the excellent and good rate of hip joint function score grade in the observation group was 73.44% (47/64), which was higher than 41.27% (26/63) in the control group, the difference was statistically significant ( Z=-3.67, P<0.05), there was no statistically significant difference between the two groups at 3 months postoperatively ( P>0.05). At 1 month after the operation, the excellent and good rate of sleep quality score grades in the observation group was 81.25% (52/64), which was higher than 57.14% (36/63) in the control group, and the difference was statistically significant ( Z=-3.00, P<0.05). Conclusions:Incorporating a reduced-positioning restrictions nursing program into the perioperative management of THA does not increase the risk of prosthesis dislocation. This approach enhances patient comfort, improves sleep quality, increases self-care ability, and supports the recovery of hip joint function.

Endometriosis is a common estrogen-dependent disease in women of childbearing age,often leading to chronic pelvic pain,infertility,ovarian cancer,and other serious complications,and jeopardizing the health of women.The pathogenesis of endometriosis is complex and involves the alteration of multiple signaling pathways mediated by hormones,immunity,genetics,and the environment,and their interactions.Wnt/β-catenin signaling is involved in the regulation of embryonic development and tissue homeostasis,and it has recently been implicated in the pathogenesis of endometriosis via multiple pathways.This review considers the biological characteristics of the Wnt/β-catenin signaling pathway and summarizes the main mechanisms and signaling pathways involved in the pathogenesis of endometriosis,as well as the curr-ent research status of the regulation of this signaling pathway by traditional Chinese medicine for the treatment of endometriosis.We aim to clarify how the Wnt/β-catenin signaling pathway affects the development of endometriosis,and suggest that future studies should focus on exploring its potential role as an indicator for the clinical prediction and early diagnosis of endometriosis,thus providing theoretical support for the early diagnosis of this condition and the development of targeted drugs.

As an important immunomodulator, vitamin D is involved in the expression, proliferation and apoptosis of immune cells through binding with the vitamin D receptor of immune cells, so as to play an immunomodulatory role, which is related to chronic inflammatory diseases and autoimmune diseases. Recent studies have found that endometrial cells also express vitamin D receptors, and the expression level of relevant immune factors in endometriosis patients are correlated with vitamin D levels. Therefore, this article will review the research progress on the regulation of vitamin D levels on the immunological pathogenesis of endometriosis.

Objective To investigate the clinical utility of ultrasound parameters in diagnosing neonatal annular pancreas.Methods A total of 56 neonates with descending duodenal obstruction underwent saline-contrast ultrasound examination.Ultrasonic parameters,including dilated duodenum diameter(DDD),dilated duodenum thickness(DDT),and stenosis duodenum diameter(SDD),were measured.The cases were categorized into three groups:annular pancreas(group A,n=28),descending duodenal atresia(group B,n=3),and descending duodenal septum(group C,n=25).One-way ANOVA was employed to compare statistical differences among the three ultrasonic parameters across the groups,followed by LSD-t test for pairwise comparisons between two groups showing significant differences.Receiver operating characteristics analysis was conducted to calculate the area under the curve and determine the cut-off value if there were statistically significant differences observed.Results In group A,group B,group C,the diameters of DDD were measured as(23.2±2.4)mm,(25±1.0)mm,(19.4±2.6)mm,respectively.When comparing these three groups,there was a statistically significant difference between group A or group B and group C in terms of DDD diameter measurements(t=5.7,P＜0.05;t=3.793,P＜0.05).However,no statistically significant difference was observed between group A and group B for DDD diameter measurements(t=1.232,P＞0.05).The corresponding values for DDT were measured as(3.0±0.6)mm,(3.2±0.4)mm,and(2.4±0.3)mm,respectively.When comparing these three groups,the results showed a statistically significant differ-ence between either Group A or Group B compared to Group C in terms of DDT measurement(t=4.695,P＜0.05;t=2.778,P＜0.05).However,no statistically significant difference was found between Group A and Group B regard-ing the measurement of DDT(t=0.666,P＞0.05).The SDD measurements in the three groups were(1.9±0.3)mm,(3.6±0.8)mm,(5.5±0.7)mm,respectively.Statistical analysis using LSD-t test revealed significant differences between the three groups(t=5.521,P＜0.05;t=6.142,P＜0.05;t=25.828,P＜0.05).The sensitivity,specificity,positive predictive value,and negative predictive value for detecting annular pancreas at a cutoff of 2.3 mm were determined to be 96.4%,100%,100%,and 96.6%,respectively,with an area under the receiver operating charac-teristic curve of 0.999.Conclusion SDD could be employed for the diagnosis of neonatal annular pancreas.

Renal cell carcinoma is a common malignant tumor in urinary system with poor prognosis, and the advanced patients are prone to distant metastases such as bone, brain and lung. Common treatment modalities for renal cell carcinoma include surgery, radiotherapy, immunotherapy and targeted therapy. Tumor microenvironment plays an important role in the occurrence, pathophysiological process and treatment of renal cell carcinoma. The study of tumor microenvironment characteristics has led to significant advances in the treatment of renal cell carcinoma. At present, immunotherapy and cell therapy for renal cancer can effectively prolong the survival of patients and provide new treatment methods for patients with advanced renal cell carcinoma.

Objective:To investigate the regulatory mechanism of miR-29a-3p/ SGMS2 axis on the inflammatory response of ovarian granulosa cells (KGN). Methods:By constructing and validating overexpression and knockdown of miR-29a-3p and SGMS2 transfected KGN cell models, dual luciferase reporter gene assay was used to detect the binding of miR-29a-3p to SGMS2. MTT assay was used for detecting the cell proliferation. Fluorescence intensity of proliferating cell nuclear antigen (PCNA) and Ki67 protein were detected by immunofluorescence. Apoptosis was detected by flow cytometry. The expression levels of tumor necrosis factor-α (TNF-α), interleukin (IL)-6, IL-1β and sphingomyelin in cell supernatant were detected by enzyme-linked immunosorbent assay. The protein expression levels of Caspase-3, cleaved-Caspase-3, SGMS2 and p-p65 in KGN were detected by Western blotting. Results:miR-29a-3p had site-specific binding to SGMS2 and can negatively regulated SGMS2 expression level. Overexpression of SGMS2 in KGN cells was able to increase their levels of absorbance ( P=0.007) and enhanced the immunofluorescence intensity of the protein of PCNA and Ki67 (all P<0.001). Overexpression of SGMS2 could reduce the apoptosis rate of KGN cells ( P=0.001). Overexpression of SGMS2 increased the expression levels of TNF-α, IL-6, IL-1β and sphingomyelin (all P<0.001). The expressions of cleaved-Caspase-3, p-p65 and SGMS2 proteins were elevated in KGN cells when SGMS2 was overexpressed ( P=0.001, P<0.001, P<0.001), while knock down SGMS2, the above results had a trend of change opposite to overexpression of SGMS2. Conclusion:There is a targeted negative regulatory relationship between miR-29a-3p and SGMS2, which can promote the inflammatory response of KGN and may provide a target for the treatment of polycystic ovary syndrome.
