The OsSPL10 gene has previously been reported to positively regulate trichome development and negatively regulate salt and drought stress tolerance in rice. However, it is not clear whether this gene can be used for gene editing to create new germplasm of glabrous leaf and salt-tolerant rice. In this study, we created six rice mutants by CRISPR/Cas9-mediated editing of OsSPL10 from 'Xinfeng 2', 'Xinkedao 31', and 'Xindao 25', the main rice cultivars along the Yellow River. Visual observation and scanning electron microscopy verified that the mutants lacked trichomes on the leaves and glumes, and the expression of glabrous marker genes OsHL6, OsGL6, and OsWOX3B in mutants was down-regulated compared with that in the wild type. The net photosynthetic rate, stomatal conductance, and transpiration rate of flag leaves in the mutants were significantly higher than those in the wild type. In addition, the survival rates of the mutants were much higher than that of the wild type after 7 days of treatment with 200 mmol/L NaCl. The results of quantitative real-time polymerase chain reaction (qRT-PCR) further verified that compared with the wild type, the mutants demonstrated down-regulated expression of the salt stress-related gene OsGASR1 and up-regulated expression of OsNHX2 and OsIDS1. Statistical analysis of agronomic traits showed that the mutants had increased plant height and no significant changes in yield-related traits compared with the wild type. The six spl10 mutants created in this study not only had glabrous leaves and glumes but also demonstrated enhanced tolerance to salt stress, serving as new germplasm resources for directional breeding of rice along the Yellow River.

Objective:To investigate the prenatal ultrasound detection and prognosis of fetuses with cysts of filum terminale.Methods:A retrospective analysis was conducted on 68 fetuses with cysts of filum terminale that underwent level Ⅲ systematic ultrasound examination and were successfully followed up at the Third Affiliated Hospital of Zhengzhou University from January 2020 to June 2023. The analysis included the initial detection time, cyst size, accompanying abnormalities, whether the cysts disappeared in utero, outcomes, and postnatal follow-up. Descriptive statistical analysis was performed.Results:The earliest ultrasound detection of filum terminale cysts was at 21 weeks and 4 days of gestation, with a median length of 4.3 mm (range 2.0-19.5 mm). Among the 68 cases, 69% (47/68) were isolated filum terminale cysts, and 31% (21/68) were non-isolated filum terminale cysts. Structural abnormalities associated with non-isolated filum terminale cysts were most commonly cardiovascular (7/21, 33%), urogenital (6/21, 29%), and neurological (6/21, 29%) systems. Prenatal ultrasound follow-up was performed in 41 cases, with an intrauterine disappearance rate of 63% (26/41). The disappearance rates for isolated and non-isolated filum terminale cysts were 67% (22/33) and 4/8, respectively. The earliest disappearance was at 25 weeks of gestation, with the shortest duration being 12 days. Prenatal genetic testing was conducted in 10 cases, with no definite pathogenic variants detected. There were 10 cases of induced labor, including two cases of isolated filum terminale cysts and eight cases of non-isolated filum terminale cysts. The remaining 58 cases resulted in live births, with postnatal follow-up ranging from 3 months to 3 years, showing no abnormal findings.Conclusion:Most fetal cysts of filum terminale are isolated and can spontaneously disappear in utero, with a generally good prognosis.

The homogeneous management of outpatient services at public hospitals with multi-campus is the foundation for promoting high-quality development of hospitals. Since 2013, a large general hospital had implemented a practice of multi-campus homogeneous management of outpatient services based on the hospital′s integrated organizational structure and management system, addressing such issues as weak outpatient service capabilities in the early stages of new campus construction, lack of homogenization in management system implementation, and poor communication between cross hospital services and information. An integrated post management mode was established with multi-post service integration, cross-post personnel flow and unified job standard. An integrated outpatient quality management system was created by the strategy of " one standard" system management, " one platform" service handling, integrated quality monitoring and management, and multi-aspect service experience improvement. The integration of vertical management and flat management were promoted through the committee system, three-level management system, and functional groups. At the same time, this management practice actively leveraged the advantages of the hospital to innovate services, and promoted the interconnection of outpatient service information across hospital areas, to integrate outpatient service positions, work, services, and management across multi campuses. The satisfaction rate of outpatient patients, the pass rate of outpatient medical records, and the on-time visit rate of outpatient physicians had increased from 91.96分, 95.38%, and 91.62% in 2019 to 93.75分, 98.47%, and 93.68% in 2022, as well as the stopping rate of expert outpatient services had decreased from 5.26% to 1.86%. This practice of homogeneous management had achieved good results, so as to provide references for other hospitals to carry out homogeneous management of outpatient services in their campuses.

Objective:To observe the effect of evidence-based early activity training on postoperative delirium in patients with brain tumor resection.Methods:This study used non-contemporary comparison method, a total of 238 patients admitted to the Second Affiliated Hospital of Zhejiang University School of Medicine in 2019, were included. 121 patients who met the inclusion criteria and signed informed consent after craniotomy during January 1st,2019 to June 31th,2019 were included in the control group, and 117 patients who met the criteria and obtained informed consent after craniotomy during July 1 to December 31,2019, were included in the experimental group. Neurosurgical postoperative routine nursing care were given to the control group. The experimental group received evidence-based early activity training. The incidence of delirium, duration of delirium, Barthel Index (BI), delirium-related adverse events and other indicators of postoperative hospitalization were compared between two groups.Results:The incidence of delirium, duration of delirium and postoperative hospital stay in the experimental group were 9.5%, 2.0 (1,3) days and 7 (5,10) days, lower than 23.3%, 3.0 (1,5) days and 8 (6,11) days in control group, and the differences were statistically significant ( χ2 value was 8.17, Z value were 2.96 and -2.01, P<0.05). BI index 1 week and 1 month after discharge in the experimental group was 90 (85, 90), 100 (100, 100), higher than the control group of 90 (86, 90) and 100 (100,100), with statistically significant difference ( Z values were -2.41 and -2.46, P<0.05), the comparison of adverse events, 0 case in experimental group, 1 case in control group, there was no statistically significant difference ( χ2 value was 0.97, P>0.05). Conclusions:Early evidence-based activities in patients with brain tumor resection can reduce the incidence of postoperative delirium, shorten the duration of postoperative delirium and postoperative hospital stay, and improve the ability of patients to take care of themselves after surgery, which is safe and effective.

Objective To evaluate the influences of abnormal glucose challenge test (GCT) on pregnancy outcomes and neonatal anthropometric data in women with normal oral glucose tolerance test (OGTT).Methods Totally 214 women who delivered in the First Affiliated Hospital of Sun Yat-sen University from November 2006 to December 2007 were enrolled.50 g GCT was performed at 24-28 weeks of gestation and 75 g OGTT would be followed if GCT≥7.8 mmol/L.Those patients,whose OGTT results below the following criteria (5.3 mmoL/L,10.0 mmol/L,8.6 mmol/L,7.8 mmol/L),were classified as normal OGTT.Altogether,116 of the 214 women with abnormal GCT and normal OGTT were collected as the study group and the rest 98 women with normal GCT as the control group.The pregnant outcomes of the two groups were analyzed.The neonatal anthropometry,including birth weight,body length,head circumference and shoulder circumference,were recorded.Other neonatal anthropometric data,such as upper arm circumference,tricep skinfold thickness and hypodermic fat thickness of abdomen were measured by a tape measure within 24 hours after birth.Results (1) Pregnant outcomes:No significant difference was found in the rate of assisted vaginal delivery,polyhydramnios,premature rupture of membranes and fetal distress between the study and control group[10.3% (12/116) vs 4% (4/98),5.2% (6/116) vs 10% (10/98),13.8% (16/116) vs 17% (17/98),20.7% (24/116) vs 13% (13/98),P ＞0.05,respectively],but the rate of cesarean section,spontaneous vaginal delivery and large for gestational age babies in the study group were different from those of the control[72.4% (84/116) vs 51% (51/98),17.2%(20/116) vs 45% (44/98),25.9% (30/116) vs 6% (6/98),P ＜0.05,respectively].(2)Neonatal anthropometry:The birth weight of the study group was significantly higher than that of the control group[(3.4 ±0.4) kg vs (3.3±0.4) kg,P ＜0.05],but no significant difference was shown in any other neonatal anthropometric results between the study and control group,including body length[(49.9 ±1.3)cm vs (49.7±1.4) cm],head circumference[(33.4±1.5)cm vs (33.8±1.7) cm],shoulder circumference [(35.4±2.3)cm vs (35.0±2.3)cm],upper arm circumference[(11.0±0.7)cm vs (10.9±0.8)cm],tricep skinfold thickness[(9.7±1.0)mm vs (9.9± 1.4)mm]and hypodermic fat thickness of abdomen[(7.2±1.2)mm vs (7.2+1.0)mm;all P＞0.05].Conclusion Women with abnormal GCT alone may have no significant influences on neonatal anthropometric data,but might have more cesarean section,large for gestational age babies,and neonatal birth weight than those women with normal GCT.
