Objective:This current study aims to explore the approaches for constructing a professional clinical research system within the context of research ward development, with the ultimate objective of providing valuable guidance for the establishment and development of proficient clinical research teams.Methods:Through a comprehensive case analysis, integrating the practical experiences from clinical trials conducted in the research ward of a Class-A tertiary hospital in Beijing, along with an extensive review of relevant literature and policy studies, this paper examined the current state of domestic clinical research implementation teams. Subsequently, a series of strategies were devised to build and foster professional clinical research teams and to explore corrective measures for cultivating a dynamic professional clinical research talent ecosystem.Results:The development of full-time clinical research teams in China was rather slow, and there was a lack of mature clinical trial teams training blueprints. Drawing on the practical experience accumulated during the establishment of a professional clinical research team in a leading hospital in Beijing, it was crucial to attach utmost importance to the optimal allocation of human and material resources. This required the systematic training of principal investigators, coordinating researchers, and research assistants, as well as the setting up of a comprehensive support system, an advanced scientific research team, and a quality control unit. Moreover, the standardization of operational models of both domestic and foreign research institutions, along with the implementation of corresponding support and incentive mechanisms, and the strengthening of training and continuing education frameworks were equally significant.Conclusions:During the process of assembling a full-time clinical research team, it is of utmost significance to cultivate professional principal investigators, coordinating researchers, and research assistants. Complemented by the establishment of a comprehensive support team, a scientific research team, and a quality control team, along with corresponding support and incentive mechanisms, this is crucial for constructing a professional clinical research execution team and a sustainable talent ecosystem in the research ward. Eventually, this will drive the efficient and high-quality progress of China's pharmaceutical industry.

Objective:To analyze the clinical phenotype and the associated pathogenic genes in a family exhibiting autosomal dominant inherited optic atrophy (ADOA).Methods:A pedigree analysis was conducted on a Han Chinese family with ADOA comprising two generations and four individuals from Henan Province.The family with two ADOA patients was recruited at Henan Eye Hospital between July and October 2023.Detailed medical histories were collected for the proband and family members.Comprehensive ophthalmologic evaluations were performed, including assessments of visual acuity, visual field, fundus photography, electroretinogram (ERG), visual evoked potential (VEP), and optical coherence tomography.Additionally, hearing, electromyography, and magnetic resonance imaging were performed on the proband to assess the presence of systemic symptoms.Peripheral blood samples were collected from four family members, and whole exome sequencing (WES) was performed on the proband, with subsequent validation via Sanger sequencing for the other family members.The pathogenicity and protein struture of the novel variant were analyzed.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Henan Eye Hospital (No.HNEECKY-2019[15]).Written informed consent was obtained from each subject.Results:The proband was a 15-year-old female with a 4-year history of vision loss in the left eye and optic atrophy, mild thinning of central macular foveal thickness, locally mild thinning of ganglion cell complex layer thickness, low VEP amplitude, and partial visual field defects in both eyes, and no significant hearing impairment or dystonia on systemic examination.The proband's mother had partial optic nerve atrophy and slightly decreased central macular foveal thickness in both eyes, and mild ERG abnormalities, but no significant VEP abnormalities.WES identified a heterozygous nonsense variant c. 676C>T (p.Gln226Ter) in exon 6 of the OPA1 gene of the proband and her mother.This variant has not been previously reported in the literature, nor is it listed in the Human Gene Mutation Database, the Thousand Genomes Project, or the Genome Aggregation Database, which results in a premature termination codon at glutamine position 226.Protein structure analysis showed that p. Gln226Ter of the OPA1 protein induces alterations in the hydrogen bonding of the protein binding to surrounding residues, which in turn leads to protein function alterations.The variant was classified as potentially pathogenic according to the ACMG standards and guidelines. Conclusions:Patients in this ADOA family present with adolescent-onset optic atrophy in both eyes, with a predominance in the left eye.The c. 676C>T variant in OPA1 gene might be the causative variant in this ADOA family.Notably, this is the first report of this specific variant.

Nowadays,the prevalence of nonalcoholic fatty liver disease(NAFLD)is constantly rising in China and globally,and its incidence rate is increasing year by year,which has seriously affected human life and health.Lipophagy is molecular chaperone-mediated autophagy and has the functions of promoting lipolysis,maintaining the lipid homeostasis of hepatocytes,and alleviating hepatocyte fatty degeneration.Lipophagy has three main processes of lipid droplet catabolism,lipid droplet autophagy,and fatty acid β-oxidation,which are regulated by key genes,receptors,and enzymes.Currently,important advances have been achieved for the intervention methods of traditional Chinese medicine,Western medicine,diet,and exercise in the research on lipophagy,which provides new perspectives for the prevention and treatment strategies for NAFLD.

Objective:To compare the detection rate and time cost of different imaging methods for retinal and optic disc neovascularization in proliferative diabetic retinopathy (PDR).Methods:A cross-sectional study was conducted.Thirty-eight patients (48 eyes) with PDR were enrolled in Henan Eye Hospital from October 2019 to February 2021, including 22 males (28 eyes) and 16 females (20 eyes). The average age of the patients was (51.08±13.35) years.All patients underwent ultra-widefield imaging (UWFI), fundus fluorescein angiography (FFA), optical coherence tomography angiography (OCTA), en face optical coherence tomography (OCT), near-infrared fundus imaging (IR) combined with spectral domain OCT (SD-OCT). Wide field swept-source OCTA (WF-SS-OCTA) was performed in the patients who were unsuitable for FFA.The time required for each examination in one eye and the detection rate of neovascularization at the optic disc (NVD) and retinal neovascularization elsewhere (NVE) were recorded.This study adhered to the Declaration of Helsinki.The study protocol was approved by Henan Eye Hospital (No.HNEECKY-2021[22]). All patients were informed about the method and purpose of the study and voluntarily signed the informed consent form.Results:The mean monocular examination time costs of UWFI, IR+ SD-OCT, OCTA+ en face OCT, FFA and WF-SS-OCT was (0.51±0.13), (2.08±0.57), (5.79±0.68), (17.66±1.83) and (13.38±1.23)min, respectively.There was a significant overall difference in the mean monocular examination time among the five methods ( F=2 077.960, P<0.001). The detection rates of UWFI, IR+ SD-OCT, OCTA+ en face OCT, FFA+ WF-SS-OCT for NVE and NVD were 52.1%(25/48) and 12.5%(6/48), 81.3%(39/48) and 20.8%(10/48), 83.3%(40/48) and 27.1%(13/48), 93.8%(45/48) and 29.2%(14/48), respectively.There were significant differences in the detection rates of NVE ( χ2=26.460, P<0.001) but not in the detection rates of NVD ( χ2=4.645, P=0.200) among the various methods.Five neovascular buds were detected by OCTA in 3 eyes, but not by FFA. Conclusions:UWFI and IR+ SD-OCT are faster and non-invasive methods for the screening of NVD and NVE in PDR eyes.Compared with FFA, OCTA and en face OCT can show the shape of neovascularization more clearly.FFA provides a wide-range retinal image, but it is time-consuming and invasive.WF-SS-OCTA extends the examination range of OCTA and detects neovascularization non-invasively and faster than FFA.

Objective:To investigate the clinical efficacy in one stage reconstruction of composite defects of Achilles tendon and surrounding soft tissues with a flap transfer combined with allogeneic tendon transplantation.Methods:From July 2018 to August 2022, a total of 12 patients, including 9 males and 3 females, with a mean age of 31.5(ranged 8 to 56) years old, had surgery with flap transfer combined with transplantation of allogeneic tendon in one stage reconstruction for compound defects of Achilles tendon and soft tissue at the Department of Orthopaedics of First Affiliated Hospital of Nanchang University. The defects of Achilles tendons ranged from 4.0 to 9.0 cm, and the soft tissue defects sized from 3.0 cm × 4.0 cm to 14.0 cm × 6.0 cm. Of the 12 patients, 6 received transfers of sural neurovascular flaps, 3 with peroneal perforator flaps and 3 with free anterolateral thigh flaps(ALTF). The flaps sized from 4.0 cm × 4.5 cm to 15.0 cm×7.0 cm, and in addition, allogeneic tendon grafts were used to reconstruct the defects of Achilles tendons in all patients. All the flap donor sites were either directly sutured or covered with skin grafts. Follow-up was carried out by visits of outpatient clinic or telephone or WeChat distant interviews. The flap survival and recovery of ankle function and Achilles tendon were observed.Results:During the 3 months to 2 years of follow-up, none of the patient showed obvious immunological rejection against the transplanted allogeneic tendon. All 12 flaps survived well with the colour and texture close to the surrounding skin. No ulceration occurred in both of the donor and recipient sites. There was no re-rupture of the transplanted allogeneic tendon. At the final follow-up, ankle movement was measured at 13.4°±2.6° in dorsal extension and 33.6°±3.2° in plantar flexion. According to American Orthopaedic Foot and Ankle Society (AOFAS) ankle and hind foot function score, a score of 88.7±5.6 was achieved with 7 patients in excellent, 4 in good and 1 was acceptable.Conclusion:In patients with a composite defect of Achilles tendon and surrrounding soft tissue, the application of a flap transfer combined with a homogeneous allograft tendon transplantation in an one stage surgery is a feasible surgical procedure. It can achieve a satisfactory outcome with less trauma and fewer complications.
