Objective To comprehensively evaluate the current clinical application status of evidence regarding immunosuppressive medication compliance management in kidney transplant patients,construct review indicators,analyze the obstacles and promoting factors,and further formulate reform strategies.Methods Using the Joanna Briggs Institute evidence-based health care model as the theoretical framework,clinical nursing issues were identified,and a systematic search,evaluation,and summarization of 38 items of evidence were conducted.An evidence-based practice group was established;review indicators were constructed;review methods were clarified.Baseline reviews of systems,healthcare professionals,patients,and their families were conducted from November 1,2022,to January 31,2023.According to the review results,the obstacles and promoting factors in the process of evidence-based practice were analyzed,and corresponding strategies were formulated.Results A total of 23 review indicators were constructed.Among them,the accurate execution rate of 15 indicators was less than 60％,and the accurate execution rate of 4 indicators was 0.The main obstacles include a lack of systems and processes in departments,poor knowledge,attitude,and practice of medical staff,a lack of standardized risk assessment,and a lack of information support for out-of-hospital management.The primary promoting factors are strong organizational leadership,multidisciplinary team support,and high participation enthusiasm of recipients and their families.Corresponding reform strategies are formulated accordingly,including process and system improvement,continuous quality monitoring,enhanced standardized training and assessment,electronic health intervention for medication compliance,and involving patients and their families in the medication compliance management process.Conclusion There is a significant gap between the evidence on immunosuppressive medication compliance management in kidney transplant patients and its clinical practice.It is essential to assess the obstacles and facilitators scientifically and comprehensively in clinical situations,employ targeted reform strategies,facilitate the translation of evidence into clinical practice,and enhance the quality of nursing care.

ObjectiveTo investigate the use of contraceptive methods， and to evaluate maternal healthcare services utilization among women within 2 years in Pudong New Area of Shanghai. MethodsA cross-sectional survey was conducted using a questionnaire for women at different postpartum periods who visited a community health clinic with their children from June to November 2021. Data were analyzed using χ² test and binary logistic regression. ResultsAmong the 1 946 postpartum women surveyed， 1 934 were either married or cohabiting， and1 430 had resumed their sexual life. Among women at 4， 6， 12， 18 and 24 months postpartum， the contraceptive prevalence rates （CPR） were 92.34% （193/209）， 92.16% （235/255）， 87.31% （282/323）， 91.95% （297/323） and 90.00% （288/320）， respectively. The modern contraceptive prevalence rates （mCPR） were 87.08% （182/209）， 87.06% （222/255）， 82.04% （265/323）， 83.09% （271/323） and 85.31% （273/320）， respectively， while the unmet contraceptive needs （UMNs） were 7.66% （16/209）， 7.84% （20/255）， 11.46% （37/323）， 6.81% （22/323） and 10.00% （32/320）， respectively. The use rates of long-acting reversible contraceptive （LARC） methods among women at 6， 12， 18 and 24 months postpartum period were 0.39% （1/255）， 2.17% （7/323）， 0.31% （1/323）， and 2.81% （9/320）， respectively. Among all surveyed subjects， 32.17% （626/1 946） had received postpartum contraceptive services only once， while 27.85% （542/1 946） had not received any postpartum contraceptive services. Binary logistic regression analysis indicated that the use of contraceptive methods among postpartum women was associated with whether relevant educational services were received after childbirth and during postpartum home visits （all P<0.05）. ConclusionPostpartum women have unmet needs for contraception. Contraceptive guidance at the 42-day postnatal healthcare visit needs to be further strengthened and postpartum contraceptive education could be integrated into the pregnancy care. The quality and effectiveness of contraceptive education during delivery and postpartum home visits， and even at the 42-day postnatal healthcare visit need to be further explored.

Objective:To study the effects of different doses of X-ray irradiation on the immune microenvironment and cGAS-STING signaling pathway of hepatocellular carcinoma cells.Methods:C57BL/C mice were subcutaneously injected with Hepa 1-6 hepatocellular carcinoma cells in the right axilla to establish a subcutaneous tumor-forming hepatocellular carcinoma model. The mice were randomly divided into 0, 4, 8, 12 Gy irradiation groups, with 10 mice in each group. The body weights and tumor volumes were monitored. Specimens were collected 28 d after irradiation. The ELLSA and Flow Cytometry method was used to compare the macrophage-associated cytokines tumor necrosis factor-α (TNF-α), interferon-γ (IFN-γ), interleukin-6 (IL-6), chemokine ligand 5 (CCL5), IL-10, IL-13, transforming growth factor-β (TGF-β), IL-4 and macrophage M1, M2 phenotype ratio (M1/M2). Real-time fluorescence quantitative polymerase chain reaction (qRT-PCR) and immunoblotting assay were used to detect the expression of genes and proteins related to the cGAS-STING signaling pathway in hepatoma cells.Results:With the increase of irradiation dose, the tumor volume was significantly reduced ( F=8.42, P<0.05), the proportion of cell necrosis increased ( F=3.89, P<0.05), the content of macrophage-associated cytokines other than IL-4 increased ( F=6.32-15.50, P<0.05), and the proportion of M1 and M2 types of macrophage in the immune microenvironment of hepatocellular carcinoma tumors was elevated ( F= 5.46, 5.14, P < 0.05).The gene expression and protein expression levels of cGAS-STING signaling pathway were elevated in hepatocellular carcinoma cells (mRNA expression of cGAS and STING: F=6.35, 16.10, P<0.05; protein expression of cGAS and STING: F=71.31, 37.15, P<0.05). Conclusions:X-ray irradiation activates the cGAS-STING signaling pathway in hepatocellular carcinoma cells and contributes to the remodeling of the tumor immune microenvironment.

Malignant tumors in children are one of the most important diseases that threaten the health and quality of life of children and are the second most common cause of death in children.With the continuous improvement and progress of treatment technology, the long-term survival rate of children with tumor has been significantly improved, but both the disease itself and the treatment can impair the immune function of children, which makes them vulnerable to various infectious diseases and secondary serious complications, and even become a source of infection, endangering the health of others. Vaccination is the most cost-effective measure to prevent infectious diseases. For children with normal immune functions, the benefits of vaccination usually outweigh the disadvantages. However, there is a lack of detailed data on the vaccination situation, efficacy and safety of vaccine use for such immunocompromised tumor survivors, and there are no authoritative and uniform vaccination recommendations. This article reviewed and summarized the literature and consensus of some domestic and foreign scholars on current status of post-treatment vaccination status, efficacy and safety of vaccination for children with tumors after treatment, with the aim of providing a reference for the practice in this field in China.

Children and adults differ significantly in physiology,biochemistry and immune function,which leads to sig-nificant differences in blood transfusion strategies between children and adults.To guide the clinical transfusion practice of pediatric patients and improve the prognosis of children,the National Health Commission organized the formulation and re-lease of the health industry standard Guideline for Pediatric Transfusion(WS/T 795-2022).This paper will briefly introduce some concepts that help understand of the Standard and the preparation process of the Standard,and explain and interpret the preparation of the"scope","general provisions"and"factors to consider"of the Standard,hoping to contribute to the understanding and implementation of the Standard.

Objectives:To investigate the rate and risk factors of tip displacement of umbilical venous catheterization (UVC) in preterm infants.Methods:This was a multicenter cohort study. Study population were preterm infants admitted to 44 tertiary hospitals in China between October 2019 and August 2021. Demographic information, general clinical data, UVC indwelling conditions and related complications were collected. The primary outcome was the rate of UVC tip displacement. The observation time points were 2 d and 7 d after UVC. They were grouped according to UVC displacement, gestational age, and birth weight. Binary Logistic regression was used to analyze the risk factors of UVC tip displacement.Results:The 2 086 preterm infants had a gestational age of (29.9±2.3) weeks and a birth weight of (1 248±298) g. There were 1 106 male preterm infants (53.0%). The rate of UVC displacement at 2 d and 7 d were 34.6% (721/2 086) and 33.6% (494/1 470), respectively, with no statistically significant difference ( χ2=0.35, P=0.533). Univariate analysis indicated that male infants, small gestational age, low birth weight and small catheter diameter were all risk factors for UVC tip displacement at the 2 d time point (all P<0.05). Multivariate analysis showed that small catheter diameter was an independent risk factor for tip displacement at both 2 d ( OR=0.47, 95% CI 0.34-0.66) and 7 d ( OR=0.39, 95% CI 0.25-0.59) time points (both P<0.001). Conclusions:The rate of UVC tip displacement is high in preterm infants. It should be avoided to deliberately select a small diameter catheter for UVC, and pay attention to the imaging monitoring of the tip position after UVC.

Objective:To systematically evaluate the safety of family integrated care (FICare) model in neonatal intensive care unit (NICU).Methods:Multiple medical databases were searched for clinical studies on FICare in NICU published from January 1, 2010 to May 28, 2022. The quality of the literature was evaluated using Risk?of?Bias?2 tool?and cohort evaluation criteria from the Cochrane Systematic Evaluation Manual depending on the types of studies included. Meta-analysis was performed using Review Manager 5.3 software.Results:Six randomized controlled trials and four cohort studies were included for meta-analysis. The results of meta-analysis showed that compared with the traditional care model, FICare model did not increase the risk of nosocomial infection ( RR=0.75, 95% CI 0.46-1.24, P=0.27) and unstable medical conditions ( RR=0.86, 95% CI 0.61-1.22, P=0.40). No significant difference existed in the all-cause mortality between FICare and traditional care ( RR=2.74, 95% CI 0.88-8.57, P=0.08). Conclusions:FICare does not increase the risk of nosocomial infection, unstable medical conditions and adverse events compared with traditional care. It is safe and feasible to implement FICare in NICU.

Objective:To study the clinical characteristics, diagnostic methods and genotypes of neonatal chronic granulomatous disease(CGD).Methods:From April 2013 to August 2020, neonates admitted to our hospital, diagnosed with neonatal CGD and confirmed using neutrophil respiratory burst test and genetic testing were retrospectively studied. Their clinical characteristics and diagnostic methods were summarized.Results:A total of eleven neonates with CGD were enrolled, including ten males and one female. The age of onset was 3-23 d and the age of admission was 11-28 d. 3 cases had family history. The initial symptoms were fever (10 cases) and coughing (1 case). The accompanying symptoms included coughing (6 cases), dyspnea (4 cases), skin pustules (3 cases), fever (1 case) and diarrhea (1 case). Lung CT showed patchy shadows (6 cases), pulmonary nodules (3 cases), round and irregular high-density shadow (1 case), pulmonary consolidation (1 case), pleural effusion (1 case) and pleural thickening (2 cases). CGD was pathologically diagnosed in one patient. Sputum culture showed Candida albicans (3 cases), Aspergillus fumigatum (2 cases), Aspergillus fumigatum combined with Klebsiella pneumoniae and Escherichia coli (1 case), Aspergillus fumigatum combined with Staphylococcus aureus (1 case). GM tests were positive in two cases and negative in other two cases. Blood and cerebrospinal fluid cultures were negative. White blood cell counts were (10.0-44.0)×10 9/L and C-reactive proteins were (14-165) mg/L. 11 cases had positive neutrophil respiratory burst test. Genetic tests showed CYBB gene mutations (9 cases) , NCF1 gene mutation(1 case) and NCF2 gene mutation (1 case). All cases received antibacterial and antifungal treatments for 2-5 weeks and were discharged with improvement. 8 patients survived, 5 received hematopoietic stem cell transplantation, 4 succeeded and one failed and continued to survive on oral medication. 3 cases took sulfamethoxazole, voriconazole or itraconazole orally for long periods. 3 cases died of severe infections after withdrawal of medication. Conclusions:Neonatal CGD is characterized by lung infections. Pulmonary CT shows mostly nodular or patchy shadows with occasional pulmonary consolidation or pleural effusion. It can be diagnosed by neutrophil respiratory burst test and genetic testing. X-linked CYBB gene mutations are common and autosomal recessive NCF1/NCF2 gene mutations less common.

Objective:To evaluate the efficacy and safety of umbilical venous catheterization (UVC) by using different methods to estimate the insertion depth.Methods:PubMed, Embase and The Cochrane Library, CBM (SinoMed), CNKI, VIP Database, Wanfang Database and Chinese Medical Journal Full-text Database were electronically searched for literature on randomized controlled trials (RCTs) comparing different methods for estimating the insertion depth of UVC. The search period was from the establishment date of the above databases to April 15th, 2022. If 2 or more studies were available for each pairwise comparison, a meta-analysis was conducted using the RevMan 5.3 software. However, if only 1 study was included for each pairwise comparison, SPSS 26.0 statistical software is used for statistical analysis using the chi-square test.Results:A total of 9 RCTs were included in the final meta-analysis, with a total of 1 281 infants, using 6 methods for estimating the depth of UVC. Compared with the Shukla formula, the Dunn method showed a statistically significant improvement in the correct place rate at the first UVC attempt ( RR=1.27, 95% CI 1.09-1.47, P=0.002). When comparing the Dunn method with the revised Shukla formula, the difference in the correct place rate at the first UVC attempt was statistically significant (21.4% vs. 33.5%, χ2=7.24, P=0.007). There was no statistically significant difference in the correct place rate at the first UVC attempt between the Dunn method and the formula based on BW, the JSS formula and the revised Shukla formula, and the method based on anatomical marks and the Shukla formula. There was no statistically significant difference in the incidence of UVC complications between the Dunn method and the Shukla formula, and between the method based on anatomical marks and the Shukla formula. Conclusions:Comparing to Shukla formula, Dunn method has a higher correct place rate at the first attempt. The incidence of complications is similar between the different pairwise comparison methods.

Enterotoxigenic Escherichia coli（ETEC）infection can induce watery diarrhea，leading to dehydration，electrolyte disturbance，and even death in severe cases. Recombinant B subunit/inactivated whole-cell cholera（rBS/WC）vaccine is effective in preventing ETEC infectious diarrhea. On the basis of the latest evidence on etiology and epidemiology of ETEC，as well as the effectiveness，safety，and health economics of rBS/WC vaccine，National Clinical Research Center for Child Health（The Children’s Hospital，Zhejiang University School of Medicine）and Zhejiang Provincial Center for Disease Control and Prevention invited experts to develop expert consensus on rBS/WC vaccine in prevention of ETEC infectious diarrhea. It aims to provide the clinicians and vaccination professionals with guidelines on using rBS/WC vaccine to reduce the incidence of ETEC infectious diarrhea.
