Congenital heart disease (CHD) is a congenital malformation resulting from abnormal embryonic development of the heart and great vessels, accounting for approximately 25% of all congenital malformations. Children with CHD are often complicated by short stature. Although surgical treatment can improve their growth and development to a certain extent, some children still experience growth retardation after surgery. Recombinant human growth hormone (rhGH) is the main drug for treating short stature, but its efficacy and safety in the treatment of patients with concomitant CHD warrant further investigation. This article reports six cases of children with CHD and short stature who were treated with rhGH. Through a literature review, we summarize and discuss the therapeutic efficacy, follow-up experiences, and adverse reactions of rhGH treatment, aiming to provide references for clinicians in applying rhGH to treat patients with CHD and short stature.

Objective:To explore the mechanism of kidney-protecting spirit pill for the treatment of diabetic nephropathy(DN)based on the network pharmacology and molecular docking technology.Methods:The database of TCMSP and Swiss Target Prediction was searched to obtain the active ingredients and targets of kidney-protecting spirit pill,and the intersection with the disease targets was obtained.The protein-protein interaction(PPI)network of intersection targets was constructed,GO and KEGG enrichment were analyzed.The key targets and small molecules were obtained and their interactions were verified by molecular docking.Results:A total of 60 active ingredients and 112 therapeutic DN targets were predicted.The key components were Cerevisterol,3,9-di-O-methylnissolin,Jaranol,Palmidin A and 16α-Hydroxydehydrotrametenolic acid.The key targets were PIK3CA,MAPK1,AKT1,PIK3R1 and BCL2,which were closely related to cancer-related pathways,AGE-RAGE signaling pathway,endocrine resistance,lipids and atherosclerosis pathways in diabetic complications.Conclusion:The mechanism of kidney-protecting spirit pill in the treatment of DN is characterized by multi-components,multi-targets and multi-pathways,with synergistic effects between the herbs,which provides a basis for the study of the pharmacological effects of kidney-protecting spirit pill.

Objective To investigate the diagnostic value of the medial plantar nerve in diabetic peripheral neuropathy(DPN).Methods A retrospective analysis was conducted in 114 patients with type 2 diabetes mellitus in our hospital.All the participants were divided into DPN group(n=73)and type 2 diabetes mellitus(T2DM)group(n=41)based on the presence of peripheral nerve damage.Simultaneously,35 healthy volunteers were chosen as the normal control(NC)group.General data,biochemical indexes,medial plantar nerve amplitude,conduction velocity,and abnormal rates were compared among the three groups.DPN patients were further divided into symptomatic and asymptomatic groups based on the presence of plantar paresthesia symptoms.The abnormal rate of the medial plantar nerve was compared with that of the superficial peroneal nerve and sural nerve in each group.Receiver operating characteristic(ROC)curve analysis was employed to assess the diagnostic value of the medial plantar nerve in DPN.Results The amplitude of the medial plantar nerve was significantly lower[(3.00±1.42)vs(6.64±3.76)vs(6.51±3.58)μV],the conduction velocity was markedly reduced[(46.57±7.42)vs(49.42±6.96)vs(51.22±5.34)m/s],and the abnormality rate was elevated(87.67%vs 12.20%)in T2DM group,than in NC groups(P<0.05).Spearman correlation analysis indicated a negative correlation between the medial plantar nerve amplitude and HbA1c(r=-0.267,P<0.05),while the conduction velocity showed a negative correlation with age(r=-0.157,P<0.05).In both symptomatic and asymptomatic DPN patients,the abnormal rate of the medial plantar nerve was higher than that of the superficial peroneal nerve and sural nerve(P<0.05).The area under the ROC curve was 0.942,signifying a reliable diagnostic value for DPN using the medial plantar nerve(P<0.05).Conclusions The medial plantar nerve proves valuable in the diagnosis of DPN,exhibiting higher sensitivity than the superficial peroneal nerve and sural nerve.

Objective:To recognize the overall situation of the core competency of medical professional postgraduate, analyze the advantages and disadvantages of the training process, and provide basis for better optimization and revision of training objectives and training plans.Methods:An anonymous online questionnaire was conducted among 264 postgraduates majoring in clinical medicine to recognize the cognition and self-evaluation of core competence, and analyze the differences in scores of different grades and types. SPSS 23.0 was used for independent-samples t test; and one-way analysis of variance to analyze categorical variables. Results:The doctoral degree students' core competency results were higher than those of master degree students, and those of the senior students were higher than junior students ( P<0.05). "System Improvement Ability" [master degree students (2.94±1.07), first-year students (2.82±0.97)], "Patient Management" [(first-year students (2.77±1.22)], "Academic Research" [first-year students (2.90±1.03)], and 4 other indicators were the weakness of students (all less than 3 scores). Conclusion:The students have a good sense of professional identity for doctors. The different depth of the clinical practice education is the possible cause which brings about the differences among students with different degrees. We should focus on strengthening the training for the "shortcomings" in the core competence of students.

OBJECTIVE: To explore the genetic basis for fetus with bilateral lateral ventriculomegaly. METHODS: Fetus umbilical cord blood and peripheral blood samples of its parents were collected. The fetus was subjected to chromosomal karyotyping, whilst the fetus and its parents were subjected to array comparative genomic hybridization (aCGH). The candidate copy number variation (CNV) were verified by qPCR, Application goldeneye DNA identification system was used to confirm the parental relationship. RESULTS: The fetus was found to have a normal karyotype. aCGH analysis indicated that it has carried a 1.16 Mb deletion at 17p13.3, which partially overlapped with the critical region of Miller-Dieker syndrome (MDS), in addition with a 1.33 Mb deletion at 17p12 region, which is associated with hereditary stress-susceptible peripheral neuropathy (HNPP). Its mother was also found to harbor the 1.33 Mb deletion at 17p12. qPCR analysis confirmed that the expression levels of genes from the 17p13.3 and 17p12 regions were about the half of that in the normal control, as well as the maternal peripheral blood sample. Parental relationship was confirmed between the fetus and its parents. Following genetic counseling, the parents has chosen to continue with the pregnancy. CONCLUSION The fetus was diagnosed with Miller-Dieker syndrome due to the de novo deletion at 17p13.3. Ventriculomegaly may be an important indicator for prenatal ultrasonography in fetuses with MDS.

OBJECTIVE: To explore the genetic etiology of two patients with developmental delay and intellectual disability. METHODS: Two children who were respectively admitted to Henan Provincial People's Hospital on August 29, 2021 and August 5, 2019 were selected as the study subjects. Clinical data were collected, and array comparative genomic hybridization (aCGH) was carried out on the children and their parents for the detection of chromosomal microduplication/microdeletions. RESULTS: Patient 1 was a 2-year-and-10-month female and patient 2 was a 3-year-old female. Both children had featured developmental delay, intellectual disability, and abnormal findings on cranial MRI. aCGH revealed that patient 1 has harbored arr[hg19] 6q14.2q15(84621837_90815662)×1, a 6.19 Mb deletion at 6q14.2q15, which encompassed ZNF292, the pathogenic gene for Autosomal dominant intellectual developmental disorder 64. Patient 2 has harbored arr[hg19] 22q13.31q13.33(46294326_51178264)×1, a 4.88 Mb deletion at 22q13.31q13.33 encompassing the SHANK3 gene, haploinsufficiency of which can lead to Phelan-McDermid syndrome. Both deletions were classified as pathogenic CNVs based on the guidelines of American College of Medical Genetics and Genomics (ACMG) and were not found in their parents. CONCLUSION The 6q14.2q15 deletion and 22q13-31q13.33 deletion probably underlay the developmental delay and intellectual disability in the two children, respectively. Haploinsufficiency of the ZNF292 gene may account for the key clinical features of the 6q14.2q15 deletion.

Objective:To establish a performance validation method for mNGS applied in BALF samples.Method:Hela cells were used as a representative of host cells, and simulated BALF samples were prepared by adding different concentrations of Hela cells, seven species of isolated pathogens (including Streptococcus pneumonia, Hemophilus influenza, Klebsiella pneumonia, Candida albicans, Cryptococcus neoformans, Aspergillus fumigatus, and Adenovirus), and interfering substances to sterile normal saline. Clinical BALF samples were collected simultaneously, and the results of mNGS were evaluated using traditional detection methods as a reference. The limit of detection (LOD), precision, anti-interference ability, stability, and accuracy of mNGS were determined. Results:In the simulated samples, the LOD of Streptococcus pneumoniae, Haemophilus influenzae, Klebsiella pneumoniae, Candida albicans, Cryptococcus neoformans, Aspergillus fumigatus, and Adenovirus were 150, 262, 102, 67, 96, 83 CFU/ml, and 439 copies/ml, respectively. The repeatability of the detection results for all pathogens of simulated positive BALF samples was 100%. The anti-interference test showed that the higher the concentration of human DNA, the fewer pathogen sequences detected by mNGS. Escherichia coli and Shigella sonnei were used to evaluate the ability of mNGS to distinguish closely related species. The results showed that the system could stably distinguish Escherichia coli and Shigella sonnei when the concentration of Shigella sonnei was 4, 000 CFU/ml. The stability test results showed that there was no significant change in the number of pathogen sequences detected whether after 1 to 3 freeze-thaw cycles or storage at 4 ℃, -20 ℃, or -80 ℃ for 36 h. Compared with traditional detection methods, the accuracy of 17 clinical samples was 82.4%(14/17). Continuous evaluation of clinical BALF samples simultaneously tested by mNGS and traditional methods at Tongji Hospital from October 25, 2021, to September 14, 2022, showed that the accuracy of mNGS compared to bacterial culture, fungal culture, mycobacterial culture, Mycobacterium tuberculosis culture, and conventional PCR techniques was 67.5%(472/699), 81.5%(570/699), 92.3%(335/363), 96.4%(350/363), and 86.8%(132/152), respectively. Compared with conventional PCR techniques, the accuracy of mNGS for detecting Pneumocystis jirovecii, Adenovirus, and Mycoplasma pneumoniae was 89.4%(84/94), 93.3%(56/60), and 87.1%(61/70), respectively. Conclusion:By preparing simulated BALF samples and using traditional detection methods as a reference, the performance characteristics of mNGS in detecting BALF samples can be preliminarily evaluated.

Objective:To explore the current situation of nursing human caring in hospital wards and analyze its influencing factors, so as to facilitate the development of nursing human caring practice.Methods:From July to November 2022, a total of 107 hospitals were surveyed through stratified convenience sampling method, and 4 072 ward nursing managers were recruited to finish the general information questionnaire and the ward nursing human caring status questionnaire. The general information included the region, class and type of the hospital, etc. The ward nursing human caring status questionnaire included 38 items in 5 dimensions of nursing human caring system and process, humanistic quality and training of nursing staff, humanistic environment and facilities, human caring procedures and measures, and human caring quality evaluation and improvement, with a full score of 190 points. Descriptive statistics were used to analyze the general data, independent samples t-test, ANOVA and correlation analysis were used to analyze the factors influencing the current status of nursing human caring in the ward, while multiple linear regression analysis was used to conduct a multivariate analysis. Results:The score of nursing human caring in hospital wards was 156.91±27.78. Whether the hospital had carried out nursing human caring pilot(demonstration) wards, whether the ward had previously been a hospital nursing human caring pilot(demonstration) nursing unit, the type of ward, and whether nursing managers had participated in human caring training were the influencing factors of the implication of nursing humanistic caring in wards( P<0.05). Conclusions:The practice of nursing human caring in hospital wards is at a good level, but needs to be further strengthened. Nursing managers should take systematically strategies to promote the development of nursing human caring practice.

The competency-based medical education has formed a global trend, and puts forward a greater challenge for educational design of resident training. The traditional curriculum cannot meet the goal of competency-based education as the curriculum design is lack of theoretical support. Curriculum design is the core of training content, and serves as a significant contributing factor of training outcome. Based on the six-step approach curriculum design, the theory and practice are integrated to form a curriculum design based on theoretical guidance. Through feedback evaluation, the current curriculum design is continuously improved in order to achieve a higher competency-based training quality. With the 5-year experiences and practice, preliminary reform demonstrates effectiveness. The current study hopes to share the teaching reform experiences of residency training base and provide references for colleagues of medical education.

Objective:To investigate mentor-mentee dual evaluation of the current status of mentor competency of clinical and translational research mentors, and provide the basis for mentor training focused on the mentor competences.Methods:A total of 121 clinical and translational research mentors and 170 mentees from Peking Union Medical College Hospital were enrolled. The Chinese version of the Mentor Competency Assessment (MCA) questionnaire was used to evaluate the mentor competency, including maintaining effective communication, aligning expectations, assessing understanding, fostering independence, addressing diversity, promoting professional development total 6 parts with 26 sub-items. The Likert scale was used to quantitatively evaluate the clinical and translational research mentor competency by mentor-mentee dual evaluations. And the composition and training needs of clinical and translational research mentors were investigated. SPSS 25.0 was used for t-test. Results:Seventy percent (119/170) of mentees considered the mentor guidance was very helpful, and 78.5% (95/121) of the mentors considered it necessary to carry out the mentor training. The mentee evaluation of mentor competency was significantly higher than that of mentor self-evaluation [total score (162.35±23.59) vs. (154.80±19.81), P < 0.01]. And the excellent rate of 26 sub-items by mentees and mentors were 100.0%(170/170) and 46.3%(56/121) respectively. The mentors and mentees shared the agreement of the strengths on trust-based relationship and encouraging mentees, and weaknesses on taking into account the possible prejudices in mentor-mentee relationship. Conclusion:The clinical and translational research mentors have already had good competences, but mentor training is still highly warranted. It's expected that to carry out targeted mentor training and assessment according to the mentor's competences will help to improve the construction of the medical talents training system.
