Chinese expert consensus on transradial access in percutaneous peripheral interventions

Transradial access (TRA) is a safe and comfortable approach and the preferred access for percutaneous coronary intervention. However, TRA is not widely used for peripheral interventions. Currently, there is a lack of data on patient selection, appropriate medical devices, complication prevention, and TRA adoption. Therefore, the Chinese Society of Interventional Oncology of the China Anti-Cancer Association organized nationwide experts to establish a Working Group of China Expert Consensus on TRA in percutaneous peripheral interventions in 2022, and jointly formulated this consensus to better promote the application of TRA in peripheral interventions to guide clinicians on patient selection, technical recommendations, and physician training. This consensus mainly focuses on the current situation, advantages and limitations of TRA in peripheral interventions, anatomical characteristics of the radial artery, patient selection, technical aspects, prevention and management of complications, radiation dose, and learning curve. A consensus was reached through a literature evaluation and by referring to the opinions of the expert group.

Construction and Validation of a Diagnostic Scoring System for Predicting Active Pulmonary Tuberculosis in Patients with Positive T-SPOT Based on Indicators Associated with Coagulation and Inflammation: A Retrospective Cross-Sectional Study.

Tuberculosis (TB) is a life-threatening single infectious disease, which remains a major global public health concern. This study was to establish and validate a clinically practical diagnostic scoring system for predicting active pulmonary tuberculosis (APTB) in patients with positive tuberculosis T cell spot test [T-SPOT] using indicators associated with coagulation and inflammation. A single-center retrospective cross-sectional study was performed to include patients with positive T-SOPT registered and hospitalized at Wuhan Jinyintan Hospital between January 2017 and December 2019. All patients were separated into the active pulmonary tuberculosis (APTB) group and the inactive pulmonary tuberculosis (IPTB) group, according to the diagnostic criteria from China's Expert Consensus for APTB and IPTB. Subsequently, the patients were randomized into a training set and a validation set at a ratio of 2:1. Indicators associated with coagulation and inflammation, including prothrombin time activity (PTA), activated partial thromboplastin time (APTT), thrombin time (TT), fibrinogen concentration (Fbg-C), C-reactive protein/albumin ratio (CAR), C-reactive protein/prealbumin ratio (CPR), neutrophils count/lymphocyte count ratio (NLR), platelet count/lymphocyte count ratio (PLR), monocyte count/lymphocyte count ratio (MLR), and erythrocyte sedimentation rate (ESR) were obtained from electronic medical record system (EMRS). Stepwise logistic regression was performed in the training set to build a diagnostic model for predicting APTB, which was transformed into an easily applicable scoring system via nomogram. Receiver operating characteristic (ROC) analysis, calibration curve (CC), and decision curve analysis (DCA) were conducted to evaluate the predictive performance of the established diagnostic scoring system. A total of 508 patients [training set (211 cases of APTB and 116 cases of IPTB) and validation set (103 cases of APTB and 78 cases of IPTB)] with positive T-SPOT were recruited in the study. Stepwise logistic regression showed that CPR, MLR, ESR, APTT and Fbg-C were independent predictors for APTB. The scoring system was subsequently formulated based on the abovementioned predictors, which correspond to scores of 10, 6, 7, 5, and 5, respectively. In addition, patients are more likely to be diagnosed as APTB when the cut-off score was ≥16 scores, while patients with <16 scores are more likely to be diagnosed as IPTB. The scoring system showed good predictive efficacy in both the training set [area under the curve (AUC): 0.887] and the validation set (AUC: 0.898). Furthermore, both CC and DCA confirmed the clinical utility of the scoring system. The data suggest that the combination of indicators associated with coagulation and inflammation could serve as biomarkers to identify APTB in patients with positive T-SPOT. In addition, patients with positive T-SPOT were more prone to be diagnosed with APTB when having a combined total of scores ≥16 in the scoring system.

China expert consensus on center guided home-based cardiac rehabilitation

Cardiac rehabilitation (CR) is a structured evidence-based intervention technology in chronic stage of patients with cardiovascular disease (CVD), including patient education, health behavior modification, drug treatment and exercise training. Evidence has showed that CR therapy further improved secondary prevention outcomes in patients with CVD. However, its utilization rate in China is very low. Among eligible patients, only a few have received CR treatment. Therefore, it is extremely urgent to propose new strategies to improve CR participation. Center guided home-based cardiac rehabilitation (CHBCR) is a potential effective strategy. In contrast to center-based cardiac rehabilitation (CBCR) service under medical supervision, CHBCR relies on remote guidance and indirect exercise supervision, in which patients receive CR at home, not in the traditional cardiac rehabilitation center. The purpose of this consensus is to provide the advantages, indications, contraindications, construction of CHBCR center, core components and quality control of CHBCR, in order to promote the scientific implementation of CHBCR in China, and benefit more cardiovascular disease patients.

China expert consensus on psychological prescription for patients with cardiovascular disease（2020）

There are a large number of patients with mental and psychological problems in the cardiology department. The purpose of this consensus was issued for cardiologists to improve their ability to identify and deal with mental and psychological problems and the quality of medical services for the patients.

Retrospective reinterpretation and reclassification of BRCA1/2 variants from Chinese population.

The accurate interpretation of BRCA1/2 variants becomes increasingly important in breast cancer and other related cancers including ovarian cancer, prostate cancer, pancreatic cancer and so forth. In the past decades, especially before year 2015, limitations of techniques and lack of databases and guidelines have led to possible misinterpretation of the clinical significance of sequence variants of BRCA1/2. A published study reported reclassification of some BRCA1/2 variants previously classified as variants of uncertain significance (VUS) to likely pathogenic in breast or ovarian cancer patients from Korea. However, little is known about the situation in Chinese population. We retrospectively retrieved 109 publications studying about BRCA1/2 variants of Chinese population from the year 1999 to year 2019 (March). After excluding publications of meta-analysis and publications with missing data, 72 publications were eventually retained for subsequent analysis. In total, 1,351 BRCA variants (673 BRCA1 variants and 678 BRCA2 variants) derived from 42,430 Chinese cancer patients were standardized and reinterpreted using ACMG/AMP 2015 guidelines and China Expert Consensus on BRCA variant interpretation by genetic counselors. Among the 1,351 BRCA variants, the majority of interpretation (91.7%, 1,239/1,351) remained the same as previously published. However, there were 112 (8.3%, 112/1,351) variants (64 BRCA1, 48 BRCA2) reclassified with different categories. Our results demonstrated that clinical significance of not only VUS, but also pathogenic/likely pathogenic variants varied from time to time in the Chinese population. Precise reinterpretation of BRCA1/2 variants is of crucial importance to genetic counseling or clinical decision-making for risk individuals or patients.

The prevalence of BRCA1/2 germline mutation in Chinese pan-cancer.

e13684 Background: Pathogenic variants in cancer predisposition genes BRCA1/2 confer susceptibility to breast and ovarian cancer and well-studied. But the characteristics of BRCA in other cancers is unknown, we identified and characterized BRCA germline variants in a large pan-cancer in China. Methods: NGS was performed on genomic DNA from 29,676 pan-cancer patients. Large fragment deletions were all verified by QPCR. We integrated guidelines of ACMG/AMP, ENIGMA and China expert consensus. Based on the in-house system, variants were interpreted one-by-one and classified into 5 grades: Benign (B), Likely Benign(LB), Variant of Uncertain significance(VUS), Likely pathogenic (LP), Pathogenic (P). Results: Among 29,676 patients, 300 BRCA1 mutations and 440 BRCA2 mutations were detected in our study. The proportion among P/LP/VUS/LB/B were 36.1%, 11.6%, 36.6%, 11.1% and 4.6%. Consistent with previous reports, the mutations spread around the whole genes. Missense and frameshift were most common types in BRCA1 (40%, 25.3%) and BRCA2 (42.3%, 29.3%). 192(25.9%) mutations were not reported in any of the databases. Among these newly reported mutations, 32 (16.7%) were classified as P, 62 (32.3%) LP and 98 (51%) VUS. Totally, 522 (1.8%) patients were identified with P/LP BRCA1/2 mutations. No founder mutations in Chinese population were defined, but BRCA1 5470_5477delATTGGGCA (I1824Dfs*3) and BRCA2 3109C &gt; T (Q1037*) had the highest prevalence indicating the common P/LP mutations in Chinese. On the whole, BRCA-associated hereditary cancer harbored higher P/LP percent than other cancer types (11.1% vs 0.7%). Different distribution and percent were observed in BRCA1 and BRCA2, the P/LP mutations were found in double primary cancers of breast and ovary (76.9% vs 38.5%), followed by ovarian cancer (15.5% vs 6.3%), breast cancer(3.8% vs 4.0%), endometrial cancer(1.6% vs 2.4%), prostatic cancer(1.3% vs 1.9%), pancreatic cancer (0.3% vs 1.8%), biliary tract tumor (0% vs 1%), thyroid cancer (0% vs 0.9%), NSCLC(0.2% vs 0.5%) and colorectal cancer(0.08% vs 0.4%). Except for SNV/Indels, large range heterozygous deletions were found in 9 patients, including 4 (0.6%) OC, 4 (0.2%) BC and 1 NSCLC, almost all interfering with BRCA1. Conclusions: This analysis depicted a comprehensive landscape of germline BRCA1/2 variants in Chinese pan-cancer. Besides breast and ovarian cancer, lots of other cancers also harbor BRCA germline mutation, retrospective family history and hereditary cancer risk assessment needs further study.

A comparative study on diagnostic cut points of dyslipidemia in children and adolescents in China

Objective: To compare the power of dyslipidemia diagnosis by different sets of cut points in the prediction of cardiovascular metabolic risk factors and identify the appropriate cut points for the diagnosis of dyslipidemia in children and adolescents in China. Methods: Data were obtained from the baseline survey of 'School-based Cardiovascular and Bone Health Promotion Program' in Beijing in 2017. Dyslipidemia was diagnosed by using two set of cut points. Receiver operating characteristic curve analysis was conducted to assess the power of dyslipidemia diagnosis by the two set of cut points to predict the prevalence of hypertension, obesity, high fat mass percentage and impaired fasting glucose. Results: A total of 14 390 children and adolescents were in included in the study. The prevalence rates of high TC, high LDL-C, low HDL-C, and high TG in the participants were 2.7%, 2.7%, 14.4%, and 3.7% according to 'Chinese Reference Standard', and 5.0%, 3.7%, 13.3%, and 3.5% according to 'China Expert Consensus'. Low HDL-C and high TG defined by the 'Chinese Reference Standard' had better performance for the prediction of high fat mass percentage and obesity in boys, but worse performance in girls (P<0.001). Conclusions: Using 'China Reference Standard' can increase the true positive rate in the prediction of obesity or high fat mass percentage in boys, and reduce the false positive rate in girls. The cut points for the diagnosis of dyslipidemia in Chinese children and adolescents need to be further validated by using national representative sample and in longitudinal study.

Guidelines for cardiovascular rehabilitation and secondary prevention in China 2018 simplified edition

Since the publication of China expert consensus on rehabilitation and secondary prevention of coronary heart disease in 2012, cardiac rehabilitation therapy has been developed rapidly in China. In 2015, Committee of Cardiac Rehabilitation and Prevention of Chinese Association of Rehabilitation Medicine published guidelines for rehabilitation/secondary prevention of cardiovascular diseases in China (2015 edition). The present guidelines, Guidelines for Cardiovascular Rehabilitation and Secondary Prevention in China 2018 simplified edition, were revised based on the 2015 edition and with referring to the latest updates in the relevant international guidelines published in 2017 and 2018.

Chinese expert consensus on radioactive 125I seeds interstitial implantation brachytherapy for pancreatic cancer.

Pancreatic cancer, also known as exocrine pancreatic carcinoma or pancreatic ductal adenocarcinoma, is one of the most challenging tumor entities worldwide, which is characterized as a highly aggressive disease with dismal overall prognosis. Treatment options for patients with locally advanced pancreatic cancer include surgery, chemotherapy, and radiotherapy. In many cases, surgical resection is not possible due to the advanced stage at diagnosis and poor responses to current treatments, therefore, treatment alternatives have to be performed. However, brachytherapy through radioactive 125I seeds (RIS) implantation into pancreatic cancer has been first applied in unresectable carcinoma and made accuracy curative effects. Therapeutic procedures of RIS implantation for pancreatic carcinoma were not identical in domestic medical centers, making it hard to achieve homogeneity and affecting the efficacy seriously at last. To maximize the benefits of RIS for patients with pancreatic cancer, Chinese Medical Doctor Association of Radioactive Seed Implantation Technology Expert Committee and Committee of Minimally Invasive Therapy in Oncology, Chinese Anti-Cancer Association, Radioactive Seed Therapy Branch organized and helped establish China expert consensus on RIS implantation for the treatment of pancreatic cancer, to provide a reference for clinical practices.

The China expert consensus of clinical practice for magnetically controlled capsule gastroscopy(2017, Shanghai)

Gastric diseases are very common in China, especially gastric cancer with a continuous high level of morbidity and mortality. As an important screening method of gastric diseases, magnetically-controlled-capsule-gastroscopy (MCCG) has already been widely used in medical institutions worldwide. Several clinical trials have already showed that MCCG has comparable accuracy in diagnosing gastric diseases compared with conventional gastroscopy. Furthermore, MCCG has the advantages of anesthesia free, no risks of cross infection, and excellent compliance. Thus MCCG could be a potential alternative technique of conventional gastroscopy. Based on the clinical practice of MCCG during recent years, Chinese doctors have gained a lot of experience. In order to standardize and popularize the application of MCCG, the expert consensus for the clinical application of MCCG was developed through several discussions and modifications among Chinese experts in the field of capsule endoscopy.

China expert consensus on the management of dyslipidemia in postmenopausal patients with early-stage breast cancer

Estrogen has an impact on the type of lipoproteins and the blood lipid levels, thus protecting the cardiovascular system. Postmenopausal breast cancer patients suffer a significant decrease in estrogen levels due to both physiological changes and the use of drugs, and thus have a higher risk of atherosclerotic cardiovascular diseases. Therefore, strict lipid management is required for postmenopausal breast cancer patients receiving endocrine therapy. However, no guidelines have been developed in terms of lipid management and intervention for postmenopausal breast cancer patients. The Chinese expert group of multidisciplinary management of dyslipidemia in breast cancer patients with endocrine therapy, after deep investigation into the management of dyslipidemia in postmenopausal patients with early-stage breast cancer, has developed the China Expert Consensus on Dyslipidemia Management in Postmenopausal Patients with Early-stage Breast Cancer. The Consensus clearly defines the goals and measures of interventions for dyslipidemia, hoping to effectively reduce the risk of atherosclerotic cardiovascular disease in postmenopausal breast cancer patients and further improve the long-term survival of the patients.

China Expert Consensus on Clinical Application of the Drug-Coated Balloon

Percutaneous coronary intervention (PCI) has become the mainstay in the treatment of coronary heart disease (CHD). In the past 10 years, the number of PCI procedures for CHD has maintained an annual growth of 15%–20% on average in China. As a consequence, in-stent restenosis (ISR) has become an increasingly serious problem with the wide application of coronary stents. Certainly, current treatment regimens for ISR are unsatisfactory in some aspects. Coronary artery bypass surgery has many risk factors and contradictions and a second stent implantation is associated with the risk for recurrent ISR and additional stent implantations; the rate of recurrent ISR in lesions after plain old balloon angioplasty is high (up to 27%). Therefore, all these regimens are suboptimal for the treatment of ISR. In recent years, drug-coated balloon (DCB), a novel interventional technique, has been increasingly used in coronary and peripheral artery interventions in Europe and Asia. In China, several DCB products have been or will be marketed for clinical application. The introduction of DCB provides a new choice for the treatment of coronary artery diseases in China. Based on several national and international clinical trials, >20 experienced experts in the PCI field from China have proposed the China expert consensus on clinical application of the DCB with evidence-based validation and session discussion in order to promote the standardized application of the DCB in the treatment of coronary artery diseases in China.

China's expert consensus on laparoscopic liver resection and guidelines on surgical procedures: an interpretation.

“Minimally invasive” represents a new trend in modern surgery. Laparoscopic surgeries bring many advantages including smaller local trauma, milder systemic reactions, and faster postoperative recovery. The laparoscopic techniques have been increasingly used for the treatment of liver diseases. In December 2012, the Chinese Society of Hepatic Surgery issued the Expert Consensus on Laparoscopic Liver Resection and Guidelines on Surgical Procedures (2013 Edition), in which the laparoscopic liver resection is divided into anatomic resection and non-anatomic resection.
