New insights from trio whole-exome sequencing in the children with kidney disease: A single-center retrospective cohort study.

BACKGROUND: Kidney disease of children markedly affects their health and development. Limited clinical data of early-stage kidney disease render a tremendous challenge for the accurate diagnosis. Trio whole-exome sequencing (Trio-WES) is emerging as a first-line diagnostic strategy in pediatric kidney disease, and shows important implications for the precision medicine strategies of children with kidney disease. METHODS: Trio-WES was performed in 133 Chinese children with kidney disease and their parents. The results for casual variants in genes known to cause kidney disease were analyzed. We further assessed the genetic diagnostic yield and the clinical implications of genetic testing. RESULTS: An overall diagnostic yield of 52.63% (70/133) was found, and the diagnostic rates ranged from 44.74% to 59.62% in different clinical phenotypes. The diagnostic yield of the three groups of simple proteinuria, renal insufficiency, and "other" was 50%, 50%, and 54.55%, respectively. Eight-seven diagnostic variants were identified in 70 probands with variants spanning 30 genes. The top 7 genes with diagnostic variants were COL4A5 (23, 26.44%), COL4A4 (13, 14.94%), ADCK4 (7, 8.05%), CLCN5 (3, 3.45%), ACE (3, 3.45%), PKD1 (3, 3.45%), and SLC12A3 (3, 3.45%), accounting for 63.22% of all variations in the cohort. CONCLUSIONS: The retrospective cohort study summarized the clinical utility of genetic testing in 133 probands, and expanded the phenotypic and genetic profiles of kidney disease in children. Trio-WES is an efficient diagnostic tool for children with kidney disease, which facilitates the clinical diagnosis and treatment. Our findings have important implications for the precise diagnosis of childhood nephropathy and may provide clinical guideline for disease management.

[Chinese expert consensus of albumin-bound paclitaxel in the treatment of breast cancer].

Breast cancer is the most common malignant tumor of women, which seriously threatens women's health. Albumin-bound paclitaxel is the basic chemotherapy drug for breast cancer treatment. We can promote reasonable clinical medication and improve patients' quality of life by standardizing chemotherapy plans, rationally optimizing treatment strategy and managing adverse reactions of albumin-bound paclitaxel. In order to standardize the clinical application of albumin-bound paclitaxel in breast cancer, Chinese Medical Doctor Association Oncologist Branch Breast Cancer Group and International Medical Exchange Branch of China Anti-Cancer Association consulted guidelines and the latest evidence-based evidences and formulated Chinese expert consensus of albumin-bound paclitaxel in the treatment of breast cancer to provide reference for clinical diagnosis and treatment of breast cancer. The consensus mainly introduces the clinical application strategies and evidence-based evidences of albumin-bound paclitaxel in advanced therapy, neoadjuvant therapy and adjuvant therapy of breast cancer. Among them, the regimens containing albumin-bound paclitaxel are the better recommended regimens for preoperative neoadjuvant and advanced rescue therapy of breast cancer. However, there is little evidence in adjuvant therapy, so it is recommended to use albumin-bound paclitaxel cautiously. We also invited breast cancer clinical experts to vote on some controversial issues, including but not limited to the usage and dosage of albumin-bound paclitaxel, combined medication and management of peripheral neuropathy, and formed consensus recommendations for the reference of breast cancer clinical workers.

[Analysis of clinical diagnosis and treatment of Behet's disease with sore throat as the first symptom].

Objective:To summarize the clinical and diagnostic characteristics of Behet's disease with sore throat as the first symptom, so as to improve clinicians' understanding of the disease. Methods:The clinical data of 28 patients with Behet's disease who were first treated in Department of Otorhinolaryngology, Peking Union Medical College Hospital from January 2015 to January 2022 were analyzed retrospectively. All patients were examined by electronic laryngoscopy at the first visit and treated with local symptomatic therapy. Twenty-one patients were examined for C-reactive protein and blood sedimentation, and some patients were examined for immunological parameters. After the diagnosis of leukoaraiosis was confirmed, treatment was based on immunosuppression and could be supplemented with oral hormone therapy depending on the extent of the lesion and other organ involvement. Results:Sore throat was the first symptom of all patients, which could be accompanied by dysphagia or dyspnea. Endoscopy revealed oropharyngeal ulcer in 25 cases（89.3%）, laryngeal ulcer in 15 cases（53.6%）, hypopharyngeal ulcer in 14 cases（50.0%）, and adhesion of nasopharynx or throat in 8 cases（28.6%）. All patients had oral ulcer at the same time, including 21 cases（75.0%） with genital ulcer, 18 cases（64.3%） with skin damage, and 11 cases（39.3%） with eye disease. In the course of disease, there were 4 cases（14.3%） with joints involvement, 3 cases（10.7%） with nervous system disease, and 1 case（3.6%） with digestive system disease. The treatment is mainly immunosuppressive, and oral hormone therapy can be supplemented according to the extent of the disease and the involvement of other organs. Conclusion:The clinical manifestations of Behet's disease, with sore throat as the first symptom, are diverse. The ulcer may involve multiple parts of the throat, and a few patients may involve multiple systems of the whole body. Clinical attention should be paid to the early diagnosis and timely treatment to prevent or delay the involvement of the lesion in important organs or systems.

Recommendations for diagnosis and treatment of SARS-CoV-2 infection in children / 西安交通大学学报(医学版)

Children are also at high risk of novel coronavirus infection. However, as children are in the developmental stage and their phylogeny is not yet complete, adult guidelines cannot be directly copied in the diagnosis and treatment of SARS-CoV-2 infection in children. Therefore, The Second Affiliated Hospital of Xi’an Jiaotong University organized relevant professionals of Children’s Hospital. Based on the "Diagnosis and Treatment Plan for SARS-CoV-2 Infection (Trial 10th Edition)" issued by the General Office of the National Health Commission of the State Administration of Traditional Chinese Medicine, the diagnosis and treatment plan suggestions for children with novel coronavirus infection in The Second Affiliated Hospital of Xi’an Jiaotong University were formulated by referring to several instructive diagnosis and treatment plans and combining our hospital’s experience in treating children with SARS-CoV-2 infection. This recommendation makes a concise and practical description from the perspectives of epidemiology, clinical manifestations, clinical typing, treatment and nursing of children infected with SARS-CoV-2, and also makes recommendations for the diagnosis and treatment of high-risk factors and complications for the reference of front-line clinical pediatricians so as to achieve timely and reasonable diagnosis and treatment of children infected with SARS-CoV-2. Early identification and active treatment of high-risk and critically patients can minimize the harm caused by complications.

Medication Analysis of Traditional Chinese Medicine Diagnosis and Treatment Guidelines for Allergic Rhinitis Based on Clinical Efficacy Evaluation / 中国实验方剂学杂志

ObjectiveTo explore the role of efficacy evaluation methods in providing evidence for traditional Chinese medicine （TCM） clinical practice guidelines based on a demonstration study of clinical efficacy evaluation of TCM for allergic rhinitis （AR），aiming to enrich the sources of evidence for guideline development. MethodReal-world data of TCM medication for AR were collected and efficacy evaluation was carried out. SPSS 16.0 software was used to calculate the conformity of clinical syndromes，main prescriptions， and medications to the guidelines. Correlation analysis of efficacy and medications was performed according to guideline conformity to compare the differences in medications between real-world clinical applications and current guidelines. ResultA total of 198 cases were collected and the clinical medications were compared with the relevant guidelines for AR. It was found that the clinical syndrome conformity was above 70%，and in addition to the guideline syndrome，there were also syndromes in six meridians and other mixed syndromes in clinical practice. The guideline conformity of the main prescriptions used in clinical practice showed a positive correlation trend with efficacy. There were some differences between the commonly used drugs in clinical practice and those recommended by the guidelines. For example，for lung Qi deficiency and cold syndrome，drugs such as Angelicae Dahuricae Radix， Magnoliae Flos， and Schisandrae Chinensis Fructus were often used. For kidney Yang deficiency syndrome，drugs such as Atractylodis Macrocephalae Rhizoma and Ostreae Concha were often used. For spleen Qi deficiency and weakness syndrome，drugs such as Poria， Cinnamomi Ramulus， and Magnoliae Flos were used. For lung Qi deficiency and cold syndrome in children，drugs such as Chebulae Fructus， Cicadae Periostracum， Zingiberis Rhizoma， and Ginseng Radix et Rhizoma were used. For lung and spleen Qi deficiency syndrome，drugs such as Dioscoreae Rhizoma， Menthae Haplocalycis Herba， Amomi Fructus， and Zingiberis Rhizoma were used. There were also some differences in the commonly used drugs for adults and children. For example，for lung Qi deficiency and cold syndrome，adults often used Angelicae Dahuricae Radix， Magnoliae Flos， and Tribuli Fructus，while children often used Ginseng Radix et Rhizoma， Paeoniae Radix Alba， and Poria. For lung meridian hidden heat syndrome， adults often used Bupleuri Radix， Asari Radix et Rhizoma， Pinelliae Rhizoma， and Xanthii Fructus， while children often used Houttuyniae Herba， Menthae Haplocalycis Herba， Citri Reticulatae Pericarpium， and Massa Medicata Fermentata. ConclusionEffective medication regimens can be screened out based on efficacy evaluation methods，which can help supplement immediate， objective， and clinically relevant evidence of medication for the development of clinical practice guidelines in TCM from the perspective of clinical effectiveness.

The Effectiveness of Metagenomic Next-Generation Sequencing in the Diagnosis of Prosthetic Joint Infection: A Systematic Review and Meta-Analysis.

Background: A prosthetic joint infection (PJI) is a devastating complication following total joint arthroplasties with poor prognosis. Identifying an accurate and prompt diagnostic method is particularly important for PJI. Recently, the diagnostic value of metagenomic next-generation sequencing (mNGS) in detecting PJI has attracted much attention, while the evidence of its accuracy is quite limited. Thus, this study aimed to evaluate the accuracy of mNGS for the diagnosis of PJI. Methods: We summarized published studies to identify the potential diagnostic value of mNGS for PJI patients by searching online databases using keywords such as "prosthetic joint infection", "PJI", and "metagenomic sequencing". Ten of 380 studies with 955 patients in total were included. The included studies provided sufficient data for the completion of 2-by-2 tables. We calculated the sensitivity, specificity, and area under the SROC curve (AUC) to evaluate mNGS for PJI diagnosis. Results: We found that the pooled diagnostic sensitivity and specificity of mNGS for PJI were 0.93 (95% CI, 0.83 to 0.97) and 0.95 (95% CI, 0.92 to 0.97), respectively. Positive and negative likelihood ratios were 18.3 (95% CI, 10.9 to 30.6) and 0.07 (95% CI, 0.03 to 0.18), respectively. The area under the curve was 0.96 (95% CI, 0.93 to 0.97). Conclusion: Metagenomic next-generation sequencing displays high accuracy in the diagnosis of PJI, especially for culture-negative cases.

[Consideration on the construction of acupuncture and moxibustion clinical diagnosis and treatment system with the core of "differentiation of disease location": taking "treatment" of Science of Acupuncture and Moxibustion as an example].

Based on the difference between disease and syndrome differentiation of acupuncture and moxibustion and each department of TCM, i.e. internal medicine, external medicine, gynecology and pediatrics, it is believed that "differentiation of disease location" is the key of disease and syndrome differentiation of acupuncture and moxibustion. According to the disease location, in the section "treatment" of Science of Acupuncture and Moxibustion, the disorders/illness are classified as zangfu disorder, disorders of limbs and meridians, dermatological disorder, ophthalmological and otorhinolaryngological disorder, gynecological disorder, as well as qi, blood and body fluid disorder. Besides, the rules of disease and syndrome differentiation, as well as treatment characteristics of each category are explained separately. It is considered that the clinical diagnosis and treatment system of acupuncture and moxibustion should be constructed by focusing on "differentiation of disease location".

Investigation and analysis of an extensive skin injury to the back caused by accidental irradiation in interventional procedure / 中华放射医学与防护杂志

Objective:To carry out investigation and analysis of an extensive skin radiation injury to the back accidentally caused by interventional procedure and to explore the problems faced in the event with emphasis on avoiding the reoccurance of similar events in the future.Methods:The data were collected by consulting the patient′s detailed medical history, collecting and analyzing clinical diagnosis and treatment data, tracking and observing their clinical manifestations and signs. The patient′s peripheral blood samples were also collected, together with the biological dose estimated and the equipment data collected on the site of the interventional treatment hospital.Results:The whole body dose to the patient was estimated to be 0.95 Gy. The typical values of kerma rate of radiation incident on the body surface due to fluoroscopic procedures were 373.5 mGy/min in subtraction modality and 47.8 mGy/min in fluoroscopy modality, respectively. The annual effective dose to the interventional radiologist was 20.51 mSv due to his operation in long-time radiation exposure conditions, higher than 3.09 mSv for other interventional radiologists with similar workload in the same department. The whole body and local clinical manifestations of the patients were in line with radiation injury. No clear diagnosis has been obtained in several hospitals, nor can obvious treatment outcomes be obsevered.Conclusion:Combined with the biological dose estimation result and clinical manifestations, the case was diagnosed as degree Ⅳ skin radiation injury. Radiation injury is closely related to whether the operation is conducted according to the standard and the output dose of X-ray machine. Non-specialized hospitals should strengthen clinical diagnosis and treatment of radiation injury.

Understanding Diseases from Single-Cell Sequencing and Methylation.

Clinical single-cell biomedicine has become a new emerging discipline, which integrates single-cell RNA and DNA sequencing, proteomics, and functions with clinical phenomes, therapeutic responses, and prognosis. It is of great value to discover disease-, phenome-, and therapy-specific diagnostic biomarkers and therapeutic targets on the basis of the principle of clinical single-cell biomedicine. This book reviews the roles of single-cell sequencing and methylation in diseases and explores disease-specific alterations of single-cell sequencing and methylation, especially focusing on potential applications of methodologies on human single-cell sequencing and methylation, on potential correlations between those changes with pulmonary diseases, and on potential roles of signaling pathways that cause heterogeneous cellular responses during treatment. This book also emphasizes the importance of methodologies in clinical practice and application, the potential of perspectives, challenges and solutions, and the significance of single-cell preparation standardization. Alterations of DNA and RNA methylation, demethylation in lung diseases, and a deep knowledge about the regulation and function of target gene methylation for diagnosing and treating diseases at the early stage are also provided. Importantly, this book aims to apply the measurement of single-cell sequencing and methylation for clinical diagnosis and treatment and to understand clinical values of those parameters and to headline and foresee the potential values of the application of single-cell sequencing in non-cancer diseases.

Risk assessment and prevention in clinical diagnosis and treatment in implant surgery associated with systemic diseases / 口腔疾病防治

@#Patients seeking implantation often have several systemic diseases, which will introduce complications to treatment. This paper reviews the risk assessments and prevention of systemic diseases in patients with oral implant therapy with the relevant literature. The patients with cardiovascular diseases are prone to stroke and cardiac arrest, and anticoagulants and antihypertensive drugs will complicate cases. The potential risks of endocrine system diseases are infections and crises caused by unstable hormone levels. The risks of respiratory diseases are dyspnea and swallowing devices. The difficulty of treating patients with neuropsychiatric diseases is attributable to poor cooperation and adverse effects of the drugs. Bone and joint system diseases may decrease the success of implantation. Hematological system, digestive system and kidney diseases may lead to hemorrhage. By inquiring about detailed medical and medication history, evaluating vital signs and detecting important objective indicators, performing targeted measures, discussing with specialists, and observing patients closely, clinicians can avoid the abovementioned risks.

Application of VATS in Diagnosis and Treatment of Lung Cancer Complicated with Pneumothorax / Aplicação do VATS no Diagnóstico e Tratamento do Câncer de Pulmão Complicado com Pneumotórax

The paper aims to explore clinical symptoms and complication characteristic of lung cancer complicated with pneumothorax, analyze clinical diagnostic value of VATS, and elaborate on specific clinical programs and significance. To investigate diagnosis and therapeutic value of VATS for lung cancer complicated with pneumothorax, 1900 cases of patients with lung cancer complicated with pneumothorax were randomly selected as research objects to be treated with VATS, and then analysis of their clinical data was done. The clinical data showed that many patients were not clearly diagnosed before operation. In VATS operation, lung tumor tissue was removed and then immediately frozen and sliced. Appropriate surgical approach was chosen based on specific circumstances of patients. As can be known from the results, 1000 cases were treated with wedge resection of lung tumor under thoracoscopy, 900 cases were treated with assisted small incision surgery under thoracoscopy. 1400 cases of lung metastasis were treated with pleural friction fixation. All the operations were successful, with pathology being clearly diagnosed. After surgery, 8 patients had mild air leakage, which could be heal without special treatment. There was no perioperative death. The above analysis shows that VATS can clearly diagnose peripheral lung tumor, and fundamentally cure pneumothorax and lung cancer, which is thus recommended in clinic.

o artigo pretende explorar sintomas clínicos e complicações características do câncer de pulmão complicado com pneumotórax, analisar o valor do diagnóstico clínico do VATS e elaborar programas e significados clínicos específicos. Para investigar o diagnóstico e valor terapêutico do VATS para câncer de pulmão complicado com pneumotórax, 1900 casos de pacientes com câncer de pulmão complicado com pneumotórax foram selecionados aleatoriamente como objetos de pesquisa para serem tratados com VATS e, em seguida, foi feita a análise de seus dados clínicos. Os dados clínicos mostraram que muitos pacientes não foram corretamente diagnosticados antes da operação. Na operação VATS, o tecido do tumor pulmonar foi removido e imediatamente congelado e cortado em fatias. A abordagem cirúrgica apropriada foi escolhida com base em circunstâncias específicas dos pacientes. Como pode ser conhecido a partir dos resultados, 1000 casos foram tratados com ressecção em cunha do tumor pulmonar sob toracoscopia, 900 casos foram tratados com cirurgia de incisão pequena assistida sob toracoscopia. 1400 casos de metástases pulmonares foram tratados com fixação de fricção pleural. Todas as operações foram bem-sucedidas, sendo a patologia claramente diagnosticada. Após a cirurgia, 8 pacientes apresentaram vazamento de ar leve, que pode ser curado sem tratamento especial. Não houve morte perioperatória. A análise acima mostra que a VATS pode diagnosticar claramente o tumor pulmonar periférico, e fundamentalmente curar pneumotórax e câncer de pulmão, o que é recomendado na clínica.

Sarcopenia as a severe organ failure, its diagnosing and present therapeutic possibilities.

Sarcopenia is defined as generalized and progressive age-related loss of skeletal muscle mass, muscle strength and physical performance below a defined threshold. In sarcopenia skeletal muscle mass - the largest body organ - is failing in its function and the term "muscle failure" was suggested. Sarcopeniat is now recognized as a serious clinical problem compromising healthy aging concept and quality of life of affected older people. Sarcopenia has a complex multifactorial pathogenesis, which involves not only age-related changes in neuromuscular function, muscle protein turnover, and hormone levels and sensitivity, but also a chronic pro-inflammatory state, oxidative stress, and behavioral factors - particularly nutritional status and degree of physical activity. The paper provides detailed review of screening and diagnostic methods and consensus-based cut off values and biomarkers of potential patophysiologic mechanisms involved in sarcopenia development in individual patient. Further, detailed description of current preventive and therapeutic strategies for sarcopenia is included. These involve structured physical activities, namely progressive resistance training and aerobic activities which prevent muscle loss and improve muscle performance. The effect of exercise is enhanced by nutritional supplementation, particularly through proteoanabolic effect of proteins and some amino acids. There are no currently registered drugs with indication of sarcopenia but there are promising substances in higher phases of clinical trials (such as antimyostatin human monoclonal antibodies, selective androgen receptor modulators) which have the potential to be introduced into clinical practice soon. Conclusions Sarcopenia is a new clinical diagnosis of organ failure of the skeletal muscle function leading to multiple adverse health outcomes. Physicians should be aware of clinical symptoms and diagnostic algorithm and target treatment according to sarcopenia leading causes. Key words: clinical diagnosis and treatment - muscle failure - muscle mass, strength and function - sarcopenia.

Clinical Decision Support System on Basis of Case-Based Reasoning for Traditional Chinese Medicine / 世界科学技术-中医药现代化

Real world clinical diagnosis and treatment activity is a complicated decision-making task. The effective clinical cases of traditional Chinese medicine (TCM) of highly experienced physicians play an important role in the routine diagnosis and treatment and the formulation of medical knowledge . Based on TCM electronic medical record data, this paper proposed a decision support prototype system on TCM clinical diagnosis and treatment based on TCM effective clinical cases and case-based reasoning (CBR) algorithm, which is used to assist inexperienced clinicians to make more reliable clinical decisions, and thereafter to improve the clinical curative effectiveness. The system integrates TCM clinical cases data set from a TCM clinical data warehouse, and retrieves the similar cases based on CBR method. In particular, according to the underlying personalized diagnosis and treatment for patients in TCM, this system implemented a flexible diagnosis and treatment modification mechanism based on correlation analysis among symptoms, diagnoses (syndrome or pattern in TCM) and medicine. Finally, through a demonstration of clinical application, we made an initial evaluation of the usefulness and practical effects of the system.
