OBJECTIVE To analyze the influencing factors of voriconazole trough concentration and adverse drug reactions （ADR） in renal transplant recipients. METHODS Data from inpatients who received voriconazole and therapeutic drug monitoring in our hospital between January 2022 and August 2023 were retrospectively analyzed. Patients were divided into renal transplant group and non-renal transplant group based on transplantation status. A 1∶1 propensity score matching （PSM） method was used to balance differences in baselines between the two groups. Voriconazole trough concentrations， target attainment rate， clinical efficacy， and ADR were compared between the two groups. Multiple linear regression （backward） was used to analyze the factors influencing voriconazole trough concentrations in the renal transplant group. Univariate analysis and binary Logistic regression were used to identify independent risk factors for ADR in the renal transplant group. RESULTS After PSM， 48 patients were included in each group. There were no statistically significant differences in the mean voriconazole trough concentration， target attainment rate or efficacy rate between the two groups （P＞0.05）. The total incidence of ADR was significantly higher in the renal transplant group than in the non-renal transplant group （P＜0.05）. Multiple linear regression analysis showed that age， average daily dose， pulmonary infection， total bilirubin during medication， day-1 loading dose， use of the original drug， concomitant immunosuppressant use， and the occurrence of ADR were factors influencing voriconazole trough concentration in renal transplant patients （P＜0.05）. Binary Logistic regression analysis showed that abnormal direct bilirubin during medication [OR＝7.747， 95%CI （1.334， 45.005）， P＝0.023] was an independent risk factor for ADR in renal transplant patients receiving voriconazole. CONCLUSIONS Age， average daily dose， pulmonary infection， use of the original drug， day-1 loading dose， total bilirubin during medication， concomitant immunosuppressant use， and the occurrence of ADR are the factors influencing voriconazole trough concentration in renal transplant patients. Furthermore， patients with abnormal direct bilirubin during medication are more susceptible to ADR.

Thoracic paravertebral nerve block(TPVB)is a regional anesthesia technique that pro-vides ipsilateral somatosensory,motor and sympathetic nerves block segmentally by injecting local anesthetics in the paravertebral space.In recent years,there has been an increasing number of studies on the use of TPVB technique for anesthesia and analgesia in pediatric thoracic and upper abdominal surgery,showing good perioperative analgesic efficacy.This article intends to provide a review of the current applica-tion and progress of TPVB technique for pediatric perioperative analgesia in terms of medication regimens,drug diffusion routes,block methods,clinical application,and complications.

Objective To investigate the protective effects of melatonin(MT)on early embryo in vitro development of mice after exposure to benzophenone-3(BP-3).Methods Fertilized mouse oocytes at the synge-neic stage were cultured in KSOM culture medium,0.8 μmol/L BP-3 culture medium,and 1×10-7 mol/L MT + 0.8 μmol/L BP-3 mixed culture medium,respectively.The rescue effect of MT on the early embryos developmental potential of BP-3-exposed mice in vitro was explored by detecting the blastocyst rate,gene transcription level,protein expression level,and the degree of DNA damage in the three groups of embryos.Results MT improved the developmental potential of mouse embryos exposed to BP-3 in vitro.Compared with the control group,MT treatment significantly increased the protein expression of ATP5A and ATP5B and decreased the DNA damage(P<0.05).Furthermore,the transcription levels of antioxidant gene Gpx1 and pluripotency related genes Pou5f1 and Cdx2 were significantly up-regulated in MT-treated blastocysts,and the expression of pro-apoptotic gene Bax was decreased.Compared with the control group,BP-3 treatment enhanced the signal intensity of γ-H2AX in blastocysts(P<0.05),while adding MT could effectively alleviate DSBs(P<0.05).Conclusion The physiological concentration of BP-3 exposure has reproductive toxicity,but the addition of appropriate con-centration of MT could significantly improve the in vitro developmental potential and quality of BP-3-exposed early embryos.

OBJECTIVE:Clinically,chronic ankle instability has symptoms such as muscle weakness,loss of control and repeated sprains.These symptoms can be effectively improved by means of exercise intervention.Here,we conducted a comprehensive quantitative evaluation of the effects of exercise intervention on chronic ankle instability at home and abroad through Meta-analysis,and examined the moderating effects of different exercise interventions on chronic ankle instability in terms of effect size and exercise dose. METHODS:CNKI,WanFang,Web of Science,EBSCO-SPORTD and PubMed were searched and screened for relevant literature regarding randomized controlled trials of an exercise intervention program against chronic ankle instability.Included literature was analyzed by using Review Manager 5.3 and Stata-SE 15. RESULTS:A total of 52 documents were included with 1 880 patients with chronic ankle instability.Meta-analysis showed that exercise intervention could improve the functional score of patients with chronic ankle instability to a large amount.Neuromuscular control training,a 12-week intervention cycle,and two weekly interventions of>60 minutes are the best protocol for improving instability symptoms in patients with chronic ankle instability.Exercise intervention could improve the dynamic balance of patients with chronic ankle instability to reach the medium equivalent stress.The best exercise program to improve the dynamic balance ability is a combination of neuromuscular control training and hip strength training,with an exercise dose of 30-60 minutes,two or three times per week,for 8 weeks in total. CONCLUSION:Different exercise forms have a good effect on improving the unstable symptoms and dynamic balance ability of patients with chronic ankle instability,among which neuromuscular control training has a more comprehensive effect on improving chronic ankle instability.It is recommended that a multifunctional combination of training forms be used as a means of rehabilitation rather than a single form of exercise.

  Objective  To evaluate the severity and features of pelvic coronal plane tilt in individuals with adolescent idiopathic scoliosis (AIS) who had lumbar curvature during the gait cycle.  Methods  AIS patients with lumbar curvature and patients with microcurvature (Cobb Angle less than 10 degrees) treated in Peking Union Medical College Hospital from September 2020 to February 2023 were retrospectively included. According to PUMC conservative classification system and Spinal Full-length Standing X-ray, AIS patients with lumbar curvature were enrolled. The bilateral iliac crest was used as the bony marker of the pelvic coronal surface, and the bilateral iliac crest height and its changes were measured during the standing position and walking cycle, so as to evaluate the degree of pelvic coronal tilt in AIS patients with lumbar curvature.  Results  A total of 209 AIS patients with lumbar curvature and 36 patients with microcurvature who met the inclusion and exclusion criteria were enrolled. The proportion of AIS patients with lumbar curvature who had a "congruent" relationship between the higher iliac crest and the convex side of the spine in standing position (iliac crest lower on the convex side than on the concave side) was significantly higher in AIS patients with lumbar curvature than patients with microcurvature(58.9% vs. 30.6%, P=0.002). AIS patients with lumbar curvature had statistically different bilateral iliac crest height change values throughout the gait cycle (including minimum, maximum, swing phase minimum, and swing phase maximum) (all P < 0.001), and the iliac crest height change values on the convex side were significantly higher than those on the concave side (all P < 0.05), whereas the patients with microcurvature did not have any statistically significant bilateral iliac crest height change values throughout the gait cycle (all P > 0.05).  Conclusion  The height of the iliac crest on the convex side of the lumbar spine is lower than that on the concave side in the standing position of AIS patients with lumbar curvature, and the value of the change of the iliac crest on the convex side of the pelvis is greater than that on the concave side in walking to maintain the balance of the body, which may provide a new direction for the intervention in the clinical rehabilitation treatment of AIS patients with lumbar curvature.

Objective: To analyze the prevalence and the risk factors of fungal sepsis in 25 neonatal intensive care units (NICU) among preterm infants in China, and to provide a basis for preventive strategies of fungal sepsis. Methods: This was a second-analysis of the data from the "reduction of infection in neonatal intensive care units using the evidence-based practice for improving quality" study. The current status of fungal sepsis of the 24 731 preterm infants with the gestational age of <34⁺⁰ weeks, who were admitted to 25 participating NICU within 7 days of birth between May 2015 and April 2018 were retrospectively analyzed. These preterm infants were divided into the fungal sepsis group and the without fungal sepsis group according to whether they developed fungal sepsis to analyze the incidences and the microbiology of fungal sepsis. Chi-square test was used to compare the incidences of fungal sepsis in preterm infants with different gestational ages and birth weights and in different NICU. Multivariate Logistic regression analysis was used to study the outcomes of preterm infants with fungal sepsis, which were further compared with those of preterm infants without fungal sepsis. The 144 preterm infants in the fungal sepsis group were matched with 288 preterm infants in the non-fungal sepsis group by propensity score-matched method. Univariate and multivariate Logistic regression analysis were used to analyze the risk factors of fungal sepsis. Results: In all, 166 (0.7%) of the 24 731 preterm infants developed fungal sepsis, with the gestational age of (29.7±2.0) weeks and the birth weight of (1 300±293) g. The incidence of fungal sepsis increased with decreasing gestational age and birth weight (both P<0.001). The preterm infants with gestational age of <32 weeks accounted for 87.3% (145/166). The incidence of fungal sepsis was 1.0% (117/11 438) in very preterm infants and 2.0% (28/1 401) in extremely preterm infants, and was 1.3% (103/8 060) in very low birth weight infants and 1.7% (21/1 211) in extremely low birth weight infants, respectively. There was no fungal sepsis in 3 NICU, and the incidences in the other 22 NICU ranged from 0.7% (10/1 397) to 2.9% (21/724), with significant statistical difference (P<0.001). The pathogens were mainly Candida (150/166, 90.4%), including 59 cases of Candida albicans and 91 cases of non-Candida albicans, of which Candida parapsilosis was the most common (41 cases). Fungal sepsis was independently associated with increased risk of moderate to severe bronchopulmonary dysplasia (BPD) (adjusted OR 1.52, 95%CI 1.04-2.22, P=0.030) and severe retinopathy of prematurity (ROP) (adjusted OR 2.55, 95%CI 1.12-5.80, P=0.025). Previous broad spectrum antibiotics exposure (adjusted OR=2.50, 95%CI 1.50-4.17, P<0.001), prolonged use of central line (adjusted OR=1.05, 95%CI 1.03-1.08, P<0.001) and previous total parenteral nutrition (TPN) duration (adjusted OR=1.04, 95%CI 1.02-1.06, P<0.001) were all independently associated with increasing risk of fungal sepsis. Conclusions: Candida albicans and Candida parapsilosis are the main pathogens of fungal sepsis among preterm infants in Chinese NICU. Preterm infants with fungal sepsis are at increased risk of moderate to severe BPD and severe ROP. Previous broad spectrum antibiotics exposure, prolonged use of central line and prolonged duration of TPN will increase the risk of fungal sepsis. Ongoing initiatives are needed to reduce fungal sepsis based on these risk factors.

  Objective  To study the demographic and clinical characteristics, correlation of genotype and phenotype and treatment of Blau syndrome to facilitate early diagnosis and timely treatment of Blau syndrome.  Methods  Seventy-two patients with Blau syndrome from 11 centers from May 2006 to April 2022 were retrospectively analyzed, and their general information, clinical data, laboratory examination and treatment medication were collected.  Results  The distribution of patients with Blau syndrome was uniform in geographical north and south of China, and there was no obvious gender bias. The mean age of onset was (14.30±12.81) months, and the age of diagnosis was (55.18±36.22) months. 35% of patients with Blau syndrome happened before 1 year old, and all patients developed before 5 years old. 87.50% (63/72) had granulomatous arthritis, 65.28% (47/72) had rash, 36.11% (26/72) had ocular involvement, 27.78% (20/72) had fever, and 15.28% (11/72) had pulmonary involvement. Arthritic manifestations of Blau syndrome were most at risk, followed by rash, ocular involvement, and fever.The first 25 months of the disease, the risk of developing a rash was the greatest. The risk of developing arthritis was the greatest between 25 months and 84 months. The main mutations were p.R334Q and p.R334W, and patients with p.R334Q mutation had relatively high incidence of fever (35.71%[5/14] vs. 14.29%[1/7], P=0.43) and ocular involvement (42.86%[6/14]vs. 28.57%[2/7], P=0.51). There was a relatively high incidence of rash (85.71%[6/7] vs. 64.29%[9/14], P=0.59) in patients with the p.R334W mutation. Forty-five patients(62.50%)were treated with a combina-tion of glucocorticoid and methotrexate. Twenty-two patients were treated with tumor necrosis factor antagonist in addition to glucocorticoid and methotrexate.  Conclusions  The risk of different clinical manifestations of Blau syndrome from high to low was arthritis, followed by rash, ocular involvement and fever. The main treatment was glucocorticoid combined with methotrexate, to which biological agents could be added.

SPSS 22.0 software was used for data statistical analysis, and the weight of each index was determined by the precedence chart method.Results:The evaluation index system consists of 3 first-level indexes, 14 second-level indexes and 42 third-level indexes, including teaching knowledge, teaching ability and teaching quality.Conclusion:The evaluation index of teaching accomplishment of nursing part-time teachers is suitable for evaluating the teaching knowledge, ability and quality of nursing part-time teachers.

Objective: To explore the heterogeneity and correlation of clinical phenotypes and genotypes in children with disorders of sex development (DSD). Methods: A retrospective study of 1 235 patients with clinically proposed DSD in 36 pediatric medical institutions across the country from January 2017 to May 2021. After capturing 277 DSD-related candidate genes, second-generation sequencing was performed to analyzed the heterogeneity and correlation combined with clinical phenotypes. Results: Among 1 235 children with clinically proposed DSD, 980 were males and 255 were females of social gender at the time of initial diagnosis with the age ranged from 1 day of age to 17.92 years. A total of 443 children with pathogenic variants were detected through molecular genetic studies, with a positive detection rate of 35.9%. The most common clinical phenotypes were micropenis (455 cases), hypospadias (321 cases), and cryptorchidism (172 cases) and common mutations detected were in SRD5A2 gene (80 cases), AR gene (53 cases) and CYP21A2 gene (44 cases). Among them, the SRD5A2 mutation is the most common in children with simple micropenis and simple hypospadias, while the AMH mutation is the most common in children with simple cryptorchidism. Conclusions: The SRD5A2 mutation is the most common genetic variant in Chinese children with DSD, and micropenis, cryptorchidism, and hypospadias are the most common clinical phenotypes. Molecular diagnosis can provide clues about the biological basis of DSD, and can also guide clinicians to perform specific clinical examinations. Target sequence capture probes and next-generation sequencing technology can provide effective and economical genetic diagnosis for children with DSD.
