Objective:To conduct a scoping review of the characteristics, functions, risk of bias and applications of home-based self-management behavior assessment tools for lung transplant patients, so as to provide references for clinical medical staff to conduct further related research.Methods:The relevant literatures were systematically searched in China National Knowledge Infrastructure, Wanfang Database, VIP, China Biology Medicine disc, PubMed, Web of Science Core Collection, Embase, Cochrane Library and CINAHL databases. The search period was from the establishment of the databases to June 30, 2023. The scoping review method framework was used to screen the literature, extract information and standardize the report.Results:A total of 10 167 Chinese and English literatures were searched, and after deduplication and screening, 23 articles that met the criteria were finally included, involving 13 home-based self-management behavior assessment tools for lung transplant patients, including nine specific tools and four universal tools. There were eight kinds of lung transplantation patients whose reliability and validity were not verified. Of the 13 tools, those with single-dimensional assessments and single measures predominate. The level of home self-management behavior of lung transplant patients was reflected mainly through compliance, and medication management was the most frequently assessed content.Conclusions:At present, the measurement of home-based self-management behavior of lung transplant patients is mainly based on questionnaire surveys, and the evaluation tools are mostly single dimensional. The reliability and validity of most evaluation tools in the population of lung transplant patients are not yet clear, and there is a certain risk of bias. It is recommended that researchers pay attention to the reliability and validity verification report of the evaluation tool in the target population when selecting it, and integrate multiple measurement methods to reduce measurement errors.

Objective:To search, evaluate and summarize the best evidence for oral fluid intake management in adult patients with urinary calculi, providing a decision-making basis for clinical nursing.Methods:Using keywords such as urolithiasis, urinary calculi, fluid intake, water intake, fluid, etc., a systematic search was conducted in relevant domestic and international databases, guideline websites, and professional association sites for evidence related to oral fluid intake management in adult urolithiasis patients. This included clinical decisions, best practices, guidelines, expert consensus, evidence summaries, systematic reviews, and recommended practices, covering the period from January 1, 2018 to June 1, 2023. Two researchers trained in evidence-based nursing independently evaluated the quality of the literature and extracted and integrated the evidence.Results:A total of 23 articles were included, comprising two clinical decisions, one best practice, four guidelines, 13 systematic reviews, and three recommended practices. Ultimately, 18 pieces of best evidence were summarized from six aspects: the importance of fluid intake, intake volume, timing of intake, the relationship between different types of fluids and the risk of urinary calculi, intake recommendations, monitoring methods, and precautions.Conclusions:This study summarizes the best evidence for oral fluid intake management in adult patients with urinary calculi, which can provide reference for clinical nursing. When applying this evidence, it is essential to fully consider clinical circumstances and patient characteristics to reduce the recurrence rate of urinary calculi.

Premature ovarian insufficiency(POI),also known as"ovarian insufficiency",has an incidence of 1％～5％.The incidence has been on the rise in recent years,seriously affecting women's physical and mental health and quality of life.At present,the cause and mechanisms of POI are still unclear,and the method and applications of model construction are also confusing.Most models have some shortcomings in pertinence and stability.The limitations greatly limit research into the clinical diagnosis and treatment of POI.This paper summarizes and discusses the etiology and pathogenesis of POI and the construction of POI animal models to provide a comprehensive reference for those studying POI.

Objective:To construct a mouse model of dextran sulfate sodium salt (DSS)-induced inflammatory bowel disease and investigate the protective effect of Bifidobacterium animalis BB69 using that model. Methods:Forty C57BL/6J mice were randomly divided into five groups: normal control group (NC group), model group (DSS group), BB69 treatment group (BB group), mesalamine treatment group (MS group), and BB69 combined with mesalamine group (BM). Except for the NC group, the other four groups were given drinking water containing 2.3% DSS for 7 d and the corresponding intervention. The condition of mice in each group was observed.Results:Compared with the mice in the DSS group, those in the BB and MS groups showed significantly reduced disease activity index ( P<0.05), improved colon shortening and edema ( P<0.05), alleviated intestinal mucosal damage and inflammatory cell infiltration, and increased expression of intestinal tight junction protein ( P<0.05). Besides, the differentiation of Treg cells and the expression of anti-inflammatory cytokines were enhanced ( P<0.05). Conclusions:Bifidobacterium animalis BB69 has a significant protective effect on mice with experimental inflammatory bowel disease.

Objective:To compare the resting energy expenditure(REE)characteristics among young men with different body mass indexes(BMI).Methods:Thirty young men[average age was(26.93± 4.16)years]were enrolled in this study.They underwent resting metabolism tests in the Department of Sports Medicine of Peking University Third Hospital from December 2017 to June 2021.The resting meta-bolic rate(RMR)was measured by indirect calorimetry,the body composition was measured by bioresis-tance antibody component analyzer.The REE characteristics were analyzed,and 11 predictive equations were used to estimate RMR and compared with the measured value.The differences were analyzed by paired t-test and intra-class correlation coefficient(ICC).Results:The RMR of the overall 30 young men was(1 960.17±463.11)kcal/d(1 kcal=4.186 8 kJ).Including(1 744.33±249.62)kcal/d in those with normal BMI,which was significantly lower than that in those who were overweight or obese[(2 104.06±520.32)kcal/d,P＜0.01],but the weight-corrected RMR in those with normal BMI was significantly higher than that in those who were overweight or obese[(24.02±2.61)kcal/(kg·d)vs.(19.98±4.38)kcal/(kg·d),P＜0.01].The RMR was significantly and positively correlated with body weight,adiposity,lean body mass,body surface area,and extracellular fluid in the subjects with diffe-rent BMI(all P＜0.05).The predicted values of the 11 prediction equations were not in good agreement with the measured values(all ICC＜0.75),with relatively high agreement between the pre-dicted and measured values of the World Health Organization(WHO)equation in overweight obese young men(ICC=0.547,P＜0.01).Conclusion:There were significant differences in RMR among young men with different BMI,and the RMR after weight correction should be considered for those who were overweight or obese.The consistency between the predicted values of different prediction equations and the actual measured values of RMR was relatively poor,and it is recommended to accurately measure RMR by indirect calorimetry.For overweight or obese young men,the WHO prediction equation can be considered to calculate RMR,but it is necessary to establish an RMR prediction equation applicable to different BMI populations.

AIM: To observe the effect of paricalcitol on intestinal ischemia-reperfusion injury, and to explore the relationship with HMGB1/TLR4/NF-κB signaling pathway. METHODS: Twenty-four SPF-grade healthy adult male C57BL/6J mice were divided into 4 groups (n=6) by random number table: sham operation group (S group), paricalcitol pretreatment+sham operation group (SP group), intestinal ischemia-reperfusion group (IR group) and paricalcitol ischemic preconditioning group (P group). S group and SP group were separated the superior mesenteric artery, IR group and P group were clamped the superior mesenteric artery for 45 minutes and then followed by reperfusion for 2 hours to establish the intestinal ischemia-reperfusion model; SP group and P group were intraperitoneally injected with 0.3 μg/kg paricalcitol 24 hours before surgery, and the other two groups were given equal volume of normal saline. The mice were sacrificed at 2 h after reperfusion, and the intestinal tissue was obtained 5 cm from the terminal ileum. The pathological results were observed under light microscope. The intestinal mucosal injury was scored according to the Chiu's scoring standard. The intestinal tissue diamine oxidase (DAO) and tumor were detected by ELISA. Necrosis factor α (TNF-α) and interleukin 6 (IL-6) content; Western blot was used to detect the expression levels of HMGB1, TLR4 and NF-κB p65 protein in small intestine tissues.RESULTS: Compared with S group and SP group, Chiu's score was increased, the expression of Dao, TNF-α and IL-6 were increased, as well as the expression of HMGB1, TLR4 and NF-κB p65 protein increased significantly in IR group (P< 0.05); Compared with IR group, Chiu's score was decreased, the expression of Dao, TNF-α and IL-6 were decreased, as well as the expression of HMGB1, TLR4 and NF-κB p65 protein decreased significantly in P group (P< 0.05). CONCLUSION: Paricalcitol can alleviate intestinal ischemia-reperfusion injury by inhibiting HMGB1/TLR4/NF-κB signaling pathway and playing an anti-inflammatory role.

Objective:To investigate the morphological characteristics of skull base in children with hemifacial microsomia (HFM) by three-dimensional reconstruction and measurement of skull base.Methods:Three-dimensional spiral CT data of HFM children with unilateral involvement who had not received any treatment from the First Center of Maxillofacial Plastic Surgery, Plastic Surgery Hospital of the Chinese Academy of Medical Sciences from February 2010 to December 2020 were collected. The patients were divided into four groups according to the Pruzansky-Kaban classification standard: Ⅰ, Ⅱa, Ⅱb and Ⅲ. The three-dimensional reconstruction and measurement of the skull base were performed using Mimics 17.0 software. Linear measurements of the skull base included the distance from tuberculum sellae to optic canal (OT), foramen rotundum (FrT), foramen ovale (FT), internal acoustic meatus (IT), hypoglossal canal (HT), and the distance from anterior clinoid process to the lesser wing of the sphenoid bone (ClS) and the petrous ridge of the temporal bone (ClP). The measurement indexes of skull base angle included anterior cranial angle (ACA), middle cranial angle (MCA), posterior cranial angle (PCA), and petrous ridge angle (PRA). SPSS 26.0 software was used for statistical analysis of the measurement result. Paired t-test was used for comparison within each group, and one-way ANOVA was used for comparison between different types. P<0.05 was statistically significant. Results:A total of 40 children with HFM were collected, with 10 cases in each group. The result of skull base angle measurement showed that the MCA of the healthy side of typeⅠHFM was significantly larger than that of the affected side, and the MCA and PRA of the healthy side of type Ⅲ HFM were larger than those of the affected side ( P<0.05). There was no significant difference in the angle of skull base between the healthy side and the affected side of typeⅡa andⅡb HFM ( P>0.05). In terms of linear distance measurement of skull base, FrT and HT on the healthy side of typeⅠHFM were longer than those on the affected side; FrT, IT, HT and ClP on the healthy side of typeⅡa HFM were significantly longer than those on the affected side; IT, HT and ClP on the healthy side of typeⅡb HFM were longer than those on the affected side; and HT on the healthy side of type Ⅲ HFM was longer than those on the affected side ( P<0.05). The difference between FrT and ClP (affected / healthy) of four types of HFM was statistically significant ( P<0.05). Conclusions:The morphology of HFM is different between the affected side and the healthy side. As for the angle of skull base, MCA was obvious smaller in the affected side than that in the healthy side in the type Ⅰ and type Ⅲ HFM. As for the linear measurement, the distance from the hypoglossal canal to the tuberculum sellae on the affected side is shorter than that on the healthy side in each type HFM, indicating that the growth and development of the cranial base on the affected side is affected in a certain degree.

OBJECTIVE：To investigate the activity of lycorine to the in vivo apoptosis of tumor cells in H 22-bearing mice and its mechanism. METHODS ：Kunming mice were inoculated subcutaneously with ascites of H 22 hepatoma mice in the armpit of forelimb to establish solid tumor model. After modeling ，mice were randomly divided into negative control group ，positive control group（hydroxycamptothecin 6 mg/kg），lycorine low-dose ，medium-dose and high-dose groups （10，20，40 mg/kg），with 10 mice in each group. Negative control group was given constant volume of normal saline intragastrically ，and administration groups were given relevant medicine intragastrically ，once a day ，for consecutive 7 days. After last medication ，the weight of tumor was detected and anti-tumor rate was calculated. Ascites tumor model of mice was established by intraperitoneal injection of H 22 hepatoma mice ascites ，and then were grouped with same method and given relevant medicine as above. After last medication ， survival time of mice was recorded and the life prolongation rate was calculated. The early apoptotic rate of tumor cells in mice was detected by flow cytometry. On the basis of normal control group （normal mice without tumor ），the mitochondrial membrane permeability of tumor cells in each group was investigated by Calcein AM staining. The changes of mitochondrial potential were investigated by Rhodamine 123 staining. Colorimetry and Western blot assay were adopted to detect the Caspase-3 activity and expression of apoptosis-related protein （Bcl-2，Bax，Cyt-C and Caspase- 9）. RESULTS ：Compared with negative control UN- group，the tumor weight of positive control group and lycorine PYSCT-2017208） groups were decreased significantly ，while the survival time was significantly prolonged ，and the early apoptotic rate of tumor cells was significantly increased （P＜0.05 or P＜0.01）；the anti-tumor rates were 39.41％ ， 23.36％ ， 36.50％ ， 56.93％，and life prolonga tion rates were 49.23％，29.09％， E-mail：ym913@yahoo.com.cn 50.19％，69.08％. Compared with normal control group ，the mitochondrial membrane permeability ，Caspase-3 protein activity and protein expression of Cyt-C and Caspase- 9 were significantly increased，while the mitochondrial membrane potential and Bcl- 2/Bax ratio were decreased significantly （P＜0.05 or P＜0.01）. Compared with negative control group ，mitochondrial membrane permeability and Bcl- 2/Bax ratio were decreased significantly in administration groups ，while mitochondrial permeability ，Caspase-3 protein activity and protein expression of Cyt-C and Caspase- 9 were significantly increased （P＜0.05 or P＜0.01）. CONCLUSIONS ：Lycorine can induce the apoptosis of tumor cells in H22-bearing mice ，the effects of which may be associated with opening mitochondrial membrane permeability transition pore to increase mitochondrial permeability ， decreasing mitochondrial membrane potential and up-regulating the expression of apoptosis-related proteins.

Objective:To preliminarily study the feasibility, safety and efficacy of transcatheter arterial chemoembolization (TACE) combined with selective portal vein embolization (SPVE) before surgical resection in the treatment of large liver cancer.Methods:A retrospective study was conducted on the clinical data of 17 patients with large liver cancer treated with TACE combined with SPVE from January 2016 to December 2019 at the Department of Hepatobiliary Surgery, the Sixth Medical Center of PLA General Hospital. The study included 15 males and 2 females, aged (59.17±10.30) years. The levels of alanine aminotransferase, tumor changes and patient survival were analyzed before operation, after TACE, and after SPVE.Results:Among the 17 patients, the levels of alanine aminotransferase on the 1st and 3rd day after SPVE was significantly higher than those after TACE [191.4 (30.5-1966.4) IU/L vs 125.3 (35.7-846.2) IU/L on the first day, and 298.5 (24.6-1334.2) IU/L vs 208.6 (21.6-775.6) IU/L on the 3rd day], all P<0.05. One month after the two combined embolism, among the 6 patients with a tumor diameter of 5-10 cm, 2 patients (33.3%) had complete remission, 3 patients (50.0%) had partial remission, and 1 patients (16.6%) had stable disease. For the tumor’s longest diameter, among the 11 patients with tumors >10 cm, 1 patient had complete remission (9.1%), 4 patients had partial remission (36.4%), 5 patients had stable diseases (45.5%), and 1 patient had disease progression (9.1%). Eventually, 11 patients underwent surgical exploration. The median residual liver volume before treatment was 329.5 (284.9-365.7) ml, and after the combined procedure 415.6 (354.7-718.8) ml. The median hyperplasia ratio was 28.1% (14.1%-51.3%). Eight patients finally underwent surgical resection. There was no death in the perioperative periods. The median tumor-free survival time was 17 (7-42) months, and the median survival time was 27 (7-42) months. Conclusion:For patients with large liver cancer with insufficient remnant liver volume, preoperative TACE+ SPVE has certain value in controlling tumor progression, promoting remnant liver hyperplasia, increasing surgical resection rate and improving prognosis.
