Objective:To analyze the current situation of low copper diet management in children with hepatolenticular degeneration, so as to provide reference and help for individualized low copper diet guidance.Methods:Questionnaire survey and semi-structured interview were used. In the questionnaire survey, a total of 113 parents of children with hepatolenticular degeneration who were treated in the Pediatric Outpatient Department and ward of Chinese Academy of Medical Sciences, Peking Union Medical College Hospital from August 2021 to October 2022 were selected as the research objects. And a self-designed Low Copper Diet Status Questionnaire for Children with Hepatolenticular Degeneration was used for investigation. In the semi-structured interview, the purposive sampling method was used to recruit research objects that met the inclusion criteria. When the information reached saturation, they were no longer included, and finally 16 interviewees were included. Results:The results of the questionnaire showed that the items with the lowest accuracy in the part of the low-copper diet knowledge questionnaire for parents of children with hepatolenticular degeneration were "whether the food was edible according to the amount of copper in the food, for example, if the copper content in 100 g food exceeded 0.5 mg, it was forbidden to eat" and "in the following bean food (tofu, yuba, dried bean curd, oily bean curd), which one had the highest copper content". Among the 113 children, 55 were completely managed by their parents on a low copper diet, 53 children were jointly managed with their parents on a low copper diet, and 4 children were self-managed on a low copper diet. A total of 64 children currently followed the principle of a low copper diet, only consuming a few major categories of foods with low copper content. A total of 32 children ensured a diversified diet while ensuring that the total copper content in their daily food did not exceed the standard. The themes extracted from semi-structured interviews included insufficient awareness of low copper diet among parents of affected children, concerns about their children dining outside, doubts about how to balance low copper diet and nutritional balance among parents, and hopes that medical staff could provide some assistance in low copper diet guidance.Conclusions:The management of low-copper diet in children with hepatolenticular degeneration is poor. The parents of the affected children lack knowledge about low copper diet and have many confusions, and there is an urgent need for medical personnel to provide more specific, rich and practical guidance on low copper diet.

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 understand the mental health status of fathers in neonatal intensive care unit and the intervention strategies for fathers′ mental health problems.Methods:Using the scoping review method as a framework, the studies on the mental health status of fathers with NICU in PubMed, CINAHL, Embase, Web of Science, Cochrane Library, PsycINFO, CNKI, WanFang Data, VIP and CBM were searched. The included studies were summarized and analyzed. The search time was from the database establishment to 30 August 2022. The content of literature extraction included author, country, publication time, research type, sample size, research variables, research content, and research results.Results:A total of twenty-five articles were included. Among them,11 literatures reported the mental health status of fathers of children in neonatal intensive care unit. Fathers experienced both negative and positive psychological changes after admission to the neonatal intensive care unit, including anxiety, depression, post-traumatic stress disorder, stress, sadness, and post-traumatic growth. Fourteen articles involved intervention strategies for mental health problems of fathers. Intervention strategies include enhancing social support (emotional support, peer support), stress management training (written disclosure, relaxation training, mindfulness therapy), information support, family integrated care (accompanied visits, kangaroo care).Conclusions:The admission of a newborn to the intensive care unit has caused many psychological problems for the father. However, there is still a lack of intervention strategies for fathers′ mental health problems, and it is still necessary for medical staff to take corresponding intervention measures according to fathers′ needs.

Objective:To integrate the experience of healthy siblings of children with chronic diseases living with their sick siblings.Methods:Cochrane Library, PubMed, Embase, Web of Science, CINAHL, PsycINFO, China National Knowledge Infrastructure, Wanfang, VIP and China Biology Medicine disc were searched for qualitative research literature on life experience of siblings of children with chronic diseases. The retrieval period was from the database construction to January 5, 2022. The quality of literature was evaluated using the qualitative research quality evaluation standard of JBI Evidence-based Health Care Center in Australia (2016) and the results were integrated using the method of pooled integration.Results:A total of 18 studies were included, 32 complete results were extracted, and the similar results were summarized to obtain 9 new categories, which were integrated into 4 integrated results, respectively, the first integrating result was that the challenges and burdens faced by healthy siblings in the process of living with their sick compatriots made them physically and mentally exhausted, the second integrating result was that the family relationship and life within the family had changed since the diagnosis of the disease, the third integrating result was that healthy siblings had limited perception ability and they were eager for information support and social support, the fourth integrating result was that with the passage of time, healthy siblings continued to adjust and adapt themselves, developed coping strategies and achieved positive personal growth.Conclusions:Children suffering from chronic diseases can adversely affect the psychosocial functions of their healthy siblings. It is suggested that the government, medical and health institutions, the public and families of children with chronic diseases should pay more attention to the psychosocial needs and life challenges of healthy siblings of children with chronic diseases, help them improve their negative emotions, improve their quality of life and further promote the healthy growth of siblings.

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.

Objective To investigate the clinical value of abnormal course of fetal superior mesenteric arteries (SMA) detected by ultrasound during the first trimester (11-13+6 weeks) in predicting congenital diaphragmatic hernia (CDH). Methods This study enrolled women who underwent fetal nuchal translucency (NT) screening during the first trimester in Central Hospital of Panyu District from March to December 2017. Low-speed high-definition flow imaging was used to observe the course of fetal SMA, and it was regarded as abnormal when the angle between SMA and abdominal aorta >90°. Once abnormal course of the SMA was suspected, the position of fetal thoracic cavity and abdominal organs would be scanned carefully. Furthermore, ultrasound examinations would be repeated at 16-18, 20-24, 28-32 and 37-40 weeks of gestation. Fetus diagnosed as CDH by ultrasound would be scheduled for MRI or autopsy to confirm the diagnosis. Pregnancy outcomes of all cases were followed up by telephone. Descriptive statistical analysis was used in this study. Results A total of 6 899 gravidas (6 964 fetuses) underwent NT scan during the first trimester were enrolled and the SMA of all fetuses were successfully displayed. Three cases with abnormal course of the SMA were identified. Two of them were diagnosed with left CDH at 17+ and 23+ weeks of gestation, which was confirmed by autopsy after termination of pregnancy, and the other one terminated pregnancy in first trimester due to a large omphalocele. Among the 6 961 fetuses with normal SMA, the pregnancy outcomes of 6 120 were successfully followed up, only one of which was found to have left CDH at 32 gestational weeks by ultrasound examination, and was later confirmed by neonatal MRI after delivery. No other fetal CDH was detected. Conclusions Abnormal course of the SMA identified in early pregnancy may be a simple and effective indicator for CDH that allow early intervention and treatment.

Objective To explore the expression of liver fatty acid binding protein (L-FABP) in tissues of hilar cholangiocarcinoma and the relationship between expression of L-FABP and clinicopathological factors and prognosis of the patients.Methods The retrospective case-control study was conducted.The clinicopathological data of 132 patients with hilar cholangiocarcinoma who were admitted to the Navy General Hospital between January 2003 and January 2013 were collected.The expression of L-FABP in tumor tissues and adjacent tissues of hilar cholangiocarcinoma and normal bile duct tissues were respectively detected by immunohistochemistry.Observation indicators:(1) expression of L-FABP by immunohistochemistry;(2) relationship between clinicopathological factors of patients and expression of L-FABP in tumor tissues;(3) follow-up and survival situations;(4) prognostic analysis of patients after radical resection of hilar cholangiocarcinoma.Follow-up using outpatient examination and telephone interview was performed to detect postoperative overall survival time up to June 2017.Count data were described as percentage and compared using the chi-square test.The survival time was calculated by the Kaplan-Meier method.Measurement data with skewed distribution were described as M (range).The univariate analysis and multivariate analysis were respectively done using the nonparametric test and COX regression model.Results (1) Expression of L-FABP by immunohistochemistry:the positive expressions of L-FABP were located in the cytoplasm.The low,moderate and high expression rates of L-FABP in tumor tissues were respectively 11.36％ (15/132),71.97％ (95/132) and 16.67％ (22/132),and positive-staining cells showed platy and / or diffuse distribution;the low,moderate and high expression rates of L-FABP in adjacent tissues of hilar cholangiocarcinoma were respectively 77.27％ (102/132),7.58％ (10/132) and 15.15％ (20/132),and positive-staining cells showed scattered or platy distribution,with a weaker staining intensity compared with tumor tissues;there was no positive expression in normal bile duct tissues.There was a statistically significant difference in expressions of L-FABP among tumor tissues and adjacent tissues of hilar cholangiocarcinoma and normal bile duct tissues (x2=5.423,P ＜ 0.05).(2) Relationship between clinicopathological factors of patients and expression of L-FABP in tumor tissues:cases with low,moderate and high expressions of L-FABP in tumor tissues were respectively 10,30,5 in 45 patients with tumor diameter ＜ 3 cm and 4,29,9 in 42 patients with 3 cm ≤ tumor diameter ≤ 5 cm and 1,36,8 in 45 patients with tumor diameter ＞ 5 cm,with a statistically significant difference (x2 =10.171,P＜ 0.05).(3) Follow-up and survival situations:132 patients were followed up for 5-90 months,with a median time of 33 months.During the followup,postoperative overall median survival time of 132 patients was 31 months.(4) Prognostic analysis of patients after radical resection of hilar cholangiocarcinoma:results of univariate analysis showed that tumor differentiation,lymph node metastasis and expressions of L-FABP in tumor tissues were related factors affecting prognosis of patients after radical resection of hilar cholangiocarcinoma (Z =1.845,3.156,1.243,P＜0.05).Results of multivariate analysis showed that tumor differentiation,lymph node metastasis and expressions of L-FABP in tumor tissues were independent factors affecting prognosis of patients after radical resection of hilar cholangiocarcinoma (odds ratio =0.431,1.806,3.692,95％ confidence interval:0.292-0.693,0.974-2.973,1.875-11.364,P＜0.05).Conclusions The high expression of L-FABP in tumor tissues is significantly correlated with the tumor diameter.Tumor differentiation,lymph node metastasis and expressions of L-FABP in tumor tissues are independent factors affecting prognosis of patients after radical resection of hilar cholangiocarcinoma.

Objective To explore the effect of medical and nursing integration notification on the truth knowing rate,anxiety,depression and quality of life in cancer patients undergoing chemotherapy. Meth-ods From February to March 2017,34 patients for the first time needing chemotherapy were included as control group,using normal disclosure.From June to July 2017,35 cases for the first time needing chemother-apy were included as the experimental group. The experimental group was informed of the medical and nurs-ing integration notification. The truth knowing rate,anxiety,depression and quality of life were compared be-fore and after three cycles of chemotherapy. Results After three cycles of chemotherapy,the truth knowing rate of patients in the experimental group (completely 57.14%,partly 34.29% and none 8.57%) was signifi-cantly different with the control group (completely 29.42%,partly 35.29% and none 35.29%,P＜0.01). The scores of anxiety and depression in the experimental group(39.43±4.60,41.86±5.23) were significantly low-er than those before chemotherapy(42.37±4.76,45.69±5.49,P＜0.01). The scores of anxiety and depression in the control group (45.74±5.20,49.74±5.42) were significantly higher than those before chemotherapy (42.77±5.62,45.56±6.27,P＜0.01).After three cycles of chemotherapy,the scores of anxiety and depression in the experimental group were lower than the control group (P＜0.01). After three cycles of chemotherapy, the total health status,body function,role function,emotional function,cognitive function,social function,fa-tigue,nausea and vomiting,and loss of appetite were statistically significant between the experimental group and control group (P＜0.05). Conclusion The medical and nursing integration notification has a positive effect on the truth knowing rate,anxiety,depression and quality of life in cancer patients undergoing chemo-therapy.

Objective To compare the effect of two procedures,named "mucosa to mucosal "and "end-inside" anastomosis for cholangiojejunostomy,and analyze its applicable scope.Methods A retrospective analysis was performed on the clinical data of 340 patients who underwent choledochojejunostomy from May 2012 to May 2017 in the Navy General Hospital.These patients were divided into two groups according to the procedure they received,including " mucosa to mucosal" anastomosis (n =249) and " end-inside"anastomosis (n =91).Two anastomotic methods of intraoperative state and postoperative complications were compared respectively under normal bile duct condition and cholangiectasis condition.Results When the common bile duct was not dilated,time spent for anastomoting in "end-inside" anastomosis was significantly shorten than that in "mucosa to mucosal" anastomosis (12.7 ± 1.2) min vs.(25.2 ± 5.8) min,and incidences of anastomotic leakage,bile duct infection,liver abscess,blie duct stricture postoperation (1.6％ vs.9.7％) in "end-inside" anastomosis were significantly lower than those in "mucosa to mucosal" anastomosis (P ＜ 0.05).Whether the common bile duct was dilated or not,the shrinking extents of stoma in " end-inside" anastomosis were lower than those in " mucosa to mucosal" anastomosis (1.4 ± 0.4) mm vs.(3.6 ± 1.2),(2.9 ± 0.6) mm vs.(4.2 ± 1.2) mm with statistical significances (P ＜ 0.05).There was no significant differences between two procedures when common bile duct was dilated.Conclusion Compared to the mucosa to mucosal anastomosis,the end-inside anastomosis had the advantage of easy operating and low postoperative complications when the bile duct was not dilated.
