Five meroterpenoids, rhodonoids K-M (1-2), daurichromene E (3), and grifolins A-B (4-5), together with seven known compounds (6-12), were isolated from Rhododendron anthopogonoides. The chemical structures of these compounds were elucidated through comprehensive analysis of high-resolution electrospray ionization mass spectrometry (HR-ESI-MS), ultraviolet (UV), infrared spectroscopy (IR), and nuclear magnetic resonance (NMR) data. Their absolute configurations were determined by comparing experimental electronic circular dichroism (ECD) spectra with computed values. Notably, compounds 1 and 3 demonstrated significant inhibitory effects on lipopolysaccharide (LPS)-induced inflammation in RAW264.7 cells. These compounds markedly suppressed the mRNA expressions of inflammatory factors, including interleukin (IL)-1β, IL-6, and tumor necrosis factor-α (TNF-α) while also down-regulating the protein expressions of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2).

OBJECTIVE:
To analyze the clinical characteristics and genotypic changes of six children with RARS2 gene variants.
METHODS:
The clinical data of 6 children with RARS2 gene variants diagnosed at the Third Affiliated Hospital of Zhengzhou University from January 2017 to August 2024 were collected. Genetic variants were detected using trio-whole exome sequencing. Genomic DNA was extracted from samples and subjected to high-throughput sequencing. Variants were detected and analyzed using relevant databases and software. Pathogenic variants were validated by Sanger sequencing. The protein structure encoded by a previously unreported variant was predicted using a SWISS-MODEL online server. This study was approved by the Medical Ethics Committee of the Third Affiliated Hospital of Zhengzhou University (Ethics No.: 2024-373-01).
RESULTS:
Among the six children, four were males and two were females, with the most recent follow-up age ranging from 1-year-and-1-month to 7 years old. The age of onset was under 1 year in all cases. All six children exhibited seizures, including infantile spasms in three, spasms and tonic spasms in one, and focal seizures in two. One child became seizure-free for 4 ~ 5 years following Valproic acid combined with topiramate and adrenocorticotropic hormone (ACTH) pulse therapy, but subsequently experienced a relapse. Another child has remained seizure-free for nearly one year with oral sodium valproate, levetiracetam, and a "cocktail" therapy. Seizures were not controlled in the remaining four children. Pontocerebellar hypoplasia was observed on neuroimaging in two children. All six patients exhibited severe psychomotor retardation. A total of 10 RARS2 gene variants were identified, three of which were previously unreported.
CONCLUSION
The predominant clinical features of Pontocerebellar hypoplasia associated with RARS2 gene variants include infantile onset, severe psychomotor retardation or regression, drug-resistant epilepsy, and feeding difficulties. The characteristic neuroimaging finding is pontocerebellar hypoplasia. However, its appearance may vary widely with time. The majority of affected children have a poor prognosis.

Objective:To investigate the effect of a rapid rehabilitation nursing model under the theoretical framework of Rogers' Science of Unitary Human Beings in the postoperative care of children undergoing radical operation on Hirschsprung's disease.Methods:A total of 91 children with Hirschsprung's disease and their parents who underwent radical surgery at the Children's Hospital Affiliated to Zhengzhou University (Henan Children's Hospital, Zhengzhou Children's Hospital) between January 2022 and January 2024 were selected by convenience sampling. Using a computer-generated random number table, they were randomly divided into an intervention group ( n=46) and a control group ( n=45). The control group received routine surgical nursing, while the intervention group received a rapid rehabilitation nursing model based on Rogers' theoretical framework in addition to routine care. Postoperative pain stress, anorectal function, gastrointestinal functional recovery, and parental satisfaction were compared between the two groups. Results:On the third postoperative day, the intervention group had lower scores on the FLACC scale, better anorectal function, and shorter times to first bowel sound, first anal exhaust, and first defecation than the control group. The overall parental satisfaction rate in the intervention group was 86.96% (40/46), higher than 51.11% (23/45) in the control group, and the differences were statistically significant (all P<0.05) . Conclusions:The rapid rehabilitation nursing model under the theoretical framework of Rogers' Science of Unitary Human Beings showed significant effectiveness in children undergoing radical operation on Hirschsprung's disease. It reduced postoperative pain, promoted recovery of anorectal and gastrointestinal function, and improved parental satisfaction.

Objective To investigate the early clinical efficacy of minimally invasive cardiac surgery coronary artery bypass grafting (MICS CABG) via left intercostal small incision for multivessel coronary artery disease. Methods The patients who received off-pump CABG in the Central China Fuwai Hospital of Zhengzhou University from June 2021 to June 2023 were enrolled. Patients were divided into two groups according to the operative technique used, including a traditional midline sternotomy group and a left intercostal small incision group. The clinical data of the two groups were compared. Results A total of 143 patients were enrolled, including 70 patients in the traditional midline sternotomy group and 73 patients in the left intercostal small incision group. The age of the patients in the left intercostal small incision group and the traditional midline sternotomy group was (63.8±8.0) years and (63.0±7.8) years, respectively; the proportions of males were 69.9% and 74.3%, respectively. The differences were not statistically significant (all P>0.05). All patients in the two groups successfully completed the operation, and no patients in the left intercostal small incision group were converted to thoracotomy. The patients in the left intercostal small incision group showed less postoperative drainage within postoperative 24 hours [(239.4±177.7) mL vs. (338.0±151.9) mL, P<0.001], lower perioperative blood transfusion rate [32.9% (24/73) vs. 51.4% (36/70), P=0.028], higher postoperative myoglobin level within postoperative 24 hours [366.1 (247.9, 513.0) ng/mL vs. 220.8 (147.2, 314.9) ng/mL, P<0.001], shorter intensive care unit stay [45.5 (31.5, 67.5) h vs. 68.0 (46.0, 78.5) h, P=0.001] and postoperative hospital stay [(10.8±4.0) d vs. (13.1±5.3) d, P=0.028] compared to the traditional midline sternotomy group. There was no significant difference in the incidence of major adverse cardiac and cerebrovascular event between the two groups [2.7% (2/73) vs. 2.9% (2/70), P=1.000]. Conclusion Compared to the full median sternotomy, MICS CABG leads to a good clinical result with smaller trauma, faster overall recovery, and less perioperative blood transfusion.

Objective To compare perioperative outcomes of minimally invasive aortic valve surgery by a right anterior minithoracotomy (RAMT) and conventional sternotomy. Methods A retrospective analysis of patients who underwent isolated aortic valve surgeries in Central China Fuwai Hospital of Zhengzhou University between May 2021 and August 2023 with a minimal incision via the RAMT approach (a RAMT group) or conventional incision via the full sternotomy approach (a conventional group). A propensity score matching analysis was performed to balance preoperative data and compare perioperative data of the two groups. Results There were 58 patients in the RAMT group, including 46 males and 12 females with an average age of (52.0±14.1) years; 128 patients were enrolled in the conventional group, including 87 males and 41 females with an average age of (60.0±12.4) years. After propensity-score matching, there were 51 patients in each group. The RAMT group had a longer average operation time, cross-clamping time and cardiopulmonary bypass time compared to the conventional group (all P<0.05). However, ICU length of stay, ventilator-assisted time and postoperative hospital stay were significantly shorter in the RAMT group (all P<0.05). Patients in the RAMT group had lower 24 hour chest drain output (P<0.05). RAMT was associated with a trend towards a lower blood transfusion rate in comparison to the sternotomy group, although this was not statistically significant (P>0.05). The occurrence of all-cause death, and perioperative complications was also similar in both groups (P>0.05). Conclusion RAMT has less trauma, faster recovery, less postoperative drainage, and shorter hospital stay than conventional approach. RAMT in patients undergoing isolated aortic valve surgery is a safe approach.

OBJECTIVE:
To explore the genetic etiology of a child with Renpenning syndrome (RS), and review the literature on the clinical characteristics and gene mutations of RS.
METHODS:
A child with RS (patient 1) who was diagnosed and treated in the Pediatric Intensive Care Unit of the Third Affiliated Hospital of Zhengzhou University in November 2023 was selected as the research object. The medical history, family history, physical examination, cerebrospinal fluid examination, echocardiography, brain magnetic resonance imaging (MRI), brain magnetic resonance angiography, cardiac coronary CT angiography and intelligence quotient (IQ) score of child 1 were retrospectively collected. Peripheral venous blood samples were collected from patient 1, his parents, sister and brother, respectively. Genomic DNA was extracted from the child and his family members, and Trios-whole exome sequencing (Trios-WES) was performed. Sanger sequencing was used to verify the pedigree. Bioinformatics softwares (Mutation Taster, REVEL, SIFT, PolyPhen-2, GERP++, SWISS-MODEL) were applied. The pathogenicity of the detected variants was rated according to the American College of Medical Genetics and Genomics (ACMG) Standards and Guidelines for the Classification of Genetic Variants (hereinafter referred to as the ACMG Guidelines). "PQBP1 gene" "Renpenning syndrome" "PQBP1 gene" "Renpenning syndrome" were used as keywords in Chinese and English, respectively. Case reports of patients with RS caused by PQBP1 gene variants were retrieved from Wanfang Data Knowledge Service Platform, China National Knowledge Infrastructure and PubMed database. The clinical features and gene variants of RS caused by PQBP1 gene variants were summarized and analyzed. This study was reviewed by the Medical Ethics Committee of the Third Affiliated Hospital of Zhengzhou University (Approval No. 2024-334-01).
RESULTS
The patient 1, a 12-year-old boy, was admitted to the hospital due to fever and disturbance of consciousness. Cerebrospinal fluid test showed viral encephalitis caused by human herpesvirus 7 infection. The main clinical manifestations were unusual facies (microcephaly, long narrow face, microphthalmos, superior oblique palpebral fissure, hypertelorism of inner canthus, bulbous nasal columella) and mental retardation. Auxiliary examination showed than patient 1 had atrial septal defect, nodular heterotopia in the posterior horn of the left ventricle, angiodysplasia, and low IQ. The disease began in infancy, and there was no family history of related diseases. A hemizygous deletion, c.459_462del (p.Arg153SerfsTer41), was identified in exon 5 of the PQBP1 gene in patient 1, which was inherited from his mother by Sanger sequencing. The results of bioinformatics analysis showed that the mutation was harmful. This variant was rated as pathogenic (PVS1+PS4+PM2_Supporting+PP3) according to ACMG Guidelines. According to the literature search strategy set in this study, a total of 13 cases of RS were retrieved, involving 16 cases of RS patient caused by PQBP1 gene mutation (patients 2-17), including patient 1, a total of 17 cases of RS. Among the 17 patients, 16 male patients had hemizygous mutations in the X chromosome PQBP1 gene, and 1 female patient had heterozygous mutations, including 12 deletion frameshift nonsense mutations, 3 point missense mutations, and 2 duplication mutations. Except for two fetuses, all patients had special facial features and low IQ to varying degrees. Ten patients had abnormal development of one or more organs such as eyes, heart, brain, etc. CONCLUSION: The main clinical manifestations of RS are developmental delay, long narrow face, bulbous nose, microcephaly, and may be accompanied by heterotopia of gray matter of ventricle and congenital heart disease. The c.459_462del (p.Arg153SerfsTer41) variant of the PQBP1 gene is the genetic basis of patient 1 in this study.
