Résumé
During the treatment of non-small cell lung cancer ( NSCLC) , many patients have developed drug resistance due to the use of targeted EGFR inhibitors. The main reasons for drug resistance are EGFR site mutations and bypass activation. Activation of ALK pathway is one of the major types of bypass activation. A recent authoritative study indicates that ALK is closely related to immunotherapy. This article reviews the treatment of ALK in tumors from three aspects: the structure and physiological function of ALK, the small molecule inhibitor of ALK, the biological function of ALK and its related treatment methods for NSCLC, and prospects future directions for better application of ALK in the treatment of NSCLC.

OBJECTIVE@#To develop and validate a user-friendly risk score for older mitral regurgitation (MR) patients, referred to as the Elder-MR score.@*METHODS@#The China Senile Valvular Heart Disease (China-DVD) Cohort Study functioned as the development cohort, while the China Valvular Heart Disease (China-VHD) Study was employed for external validation. We included patients aged 60 years and above receiving medical treatment for moderate or severe MR (2274 patients in the development cohort and 1929 patients in the validation cohort). Candidate predictors were chosen using Cox's proportional hazards model and stepwise selection with Akaike's information criterion.@*RESULTS@#Eight predictors were identified: age ≥ 75 years, body mass index < 20 kg/m2, NYHA class III/IV, secondary MR, anemia, estimated glomerular filtration rate < 60 mL/min per 1.73 m2, albumin < 35 g/L, and left ventricular ejection fraction < 60%. The model displayed satisfactory performance in predicting one-year mortality in both the development cohort (C-statistic = 0.73, 95% CI: 0.69-0.77, Brier score = 0.06) and the validation cohort (C-statistic = 0.73, 95% CI: 0.68-0.78, Brier score = 0.06). The Elder-MR score ranges from 0 to 15 points. At a one-year follow-up, each point increase in the Elder-MR score represents a 1.27-fold risk of death (HR = 1.27, 95% CI: 1.21-1.34, P < 0.001) in the development cohort and a 1.24-fold risk of death (HR = 1.24, 95% CI: 1.17-1.30, P < 0.001) in the validation cohort. Compared to EuroSCORE II, the Elder-MR score demonstrated superior predictive accuracy for one-year mortality in the validation cohort (C-statistic = 0.71 vs. 0.70, net reclassification improvement = 0.320, P < 0.01; integrated discrimination improvement = 0.029, P < 0.01).@*CONCLUSIONS@#The Elder-MR score may serve as an effective risk stratification tool to assist clinical decision-making in older MR patients.

The mixing process is a critical link in the formation of oral solid preparations of traditional Chinese medicine. This paper took the extract powder of Guizhi Fuling Capsules and Paeonol powder as research objects. The angle of repose, loose packing density, and particle size of the two powders were measured to calibrate discrete element simulation parameters for the mixing process. The discrete element method was used to calibrate the simulated solid density of Paeonol powder and extract powder of Guizhi Fuling Capsules based on the Hertz-Mindlin with JKR V2 contact model and particle scaling. The Plackett-Burman experimental design was used to screen out the critical contact parameters that had a significant effect on the simulation of the angle of repose. The regression model between the critical contact parameters and the simulated angle of repose was established by the Box-Behnken experimental design, and the critical contact parameters of each powder were optimized based on the regression model. The best combination of critical contact parameters of the extract powder of Guizhi Fuling Capsules was found to be 0.51 for particle-particle static friction coefficient, 0.31 for particle-particle rolling friction coefficient, and 0.64 for particle-stainless steel static friction coefficient. For Paeonol powder, the best combination of critical contact parameters was 0.4 for particle-particle static friction coefficient and 0.19 for particle-particle rolling friction coefficient. The best combination of contact parameters between Paeonol powder and extract powder of Guizhi Fuling Capsules was 0.27 for collision recovery coefficient, 0.49 for static friction coefficient, and 0.38 for rolling friction coefficient. The verification results show that the relative error between the simulated value and the measured value of the angle of repose of the two single powders is less than 1%, while the relative error between the simulated value and the measured value of the angle of repose of the mixed powder with a mass ratio of 1∶1 is less than 4%. These research results provide reliable physical property simulation data for the mixed simulation experiment of extract powder of Guizhi Fuling Capsules and Paeonol powder.

Résumé
Bone defects caused by different causes such as trauma, severe bone infection and other factors are common in clinic and difficult to treat. Usually, bone substitutes are required for repair. Current bone grafting materials used clinically include autologous bones, allogeneic bones, xenografts, and synthetic materials, etc. Other than autologous bones, the major hurdles of rest bone grafts have various degrees of poor biological activity and lack of active ingredients to provide osteogenic impetus. Bone marrow contains various components such as stem cells and bioactive factors, which are contributive to osteogenesis. In response, the technique of bone marrow enrichment, based on the efficient utilization of components within bone marrow, has been risen, aiming to extract osteogenic cells and factors from bone marrow of patients and incorporate them into 3D scaffolds for fabricating bone grafts with high osteoinductivity. However, the scientific guidance and application specification are lacked with regard to the clinical scope, approach, safety and effectiveness. In this context, under the organization of Chinese Orthopedic Association, the Expert consensus for the clinical application of autologous bone marrow enrichment technique for bone repair ( version 2023) is formulated based on the evidence-based medicine. The consensus covers the topics of the characteristics, range of application, safety and application notes of the technique of autologous bone marrow enrichment and proposes corresponding recommendations, hoping to provide better guidance for clinical practice of the technique.

Objective:To investigate the diagnostic accuracy of serological indicators and evaluate the diagnostic value of a new established combined serological model on identifying the minimal hepatic encephalopathy (MHE) in patients with compensated cirrhosis.Methods:This prospective multicenter study enrolled 263 compensated cirrhotic patients from 23 hospitals in 15 provinces, autonomous regions and municipalities of China between October 2021 and August 2022. Clinical data and laboratory test results were collected, and the model for end-stage liver disease (MELD) score was calculated. Ammonia level was corrected to the upper limit of normal (AMM-ULN) by the baseline blood ammonia measurements/upper limit of the normal reference value. MHE was diagnosed by combined abnormal number connection test-A and abnormal digit symbol test as suggested by Guidelines on the management of hepatic encephalopathy in cirrhosis. The patients were randomly divided (7∶3) into training set ( n=185) and validation set ( n=78) based on caret package of R language. Logistic regression was used to establish a combined model of MHE diagnosis. The diagnostic performance was evaluated by the area under the curve (AUC) of receiver operating characteristic curve, Hosmer-Lemeshow test and calibration curve. The internal verification was carried out by the Bootstrap method ( n=200). AUC comparisons were achieved using the Delong test. Results:In the training set, prevalence of MHE was 37.8% (70/185). There were statistically significant differences in AMM-ULN, albumin, platelet, alkaline phosphatase, international normalized ratio, MELD score and education between non-MHE group and MHE group (all P<0.05). Multivariate Logistic regression analysis showed that AMM-ULN [odds ratio ( OR)=1.78, 95% confidence interval ( CI) 1.05-3.14, P=0.038] and MELD score ( OR=1.11, 95% CI 1.04-1.20, P=0.002) were independent risk factors for MHE, and the AUC for predicting MHE were 0.663, 0.625, respectively. Compared with the use of blood AMM-ULN and MELD score alone, the AUC of the combined model of AMM-ULN, MELD score and education exhibited better predictive performance in determining the presence of MHE was 0.755, the specificity and sensitivity was 85.2% and 55.7%, respectively. Hosmer-Lemeshow test and calibration curve showed that the model had good calibration ( P=0.733). The AUC for internal validation of the combined model for diagnosing MHE was 0.752. In the validation set, the AUC of the combined model for diagnosing MHE was 0.794, and Hosmer-Lemeshow test showed good calibration ( P=0.841). Conclusion:Use of the combined model including AMM-ULN, MELD score and education could improve the predictive efficiency of MHE among patients with compensated cirrhosis.

Purpose@#Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the pathogen of coronavirus disease 2019. Diagnostic methods based on the clustered regularly interspaced short palindromic repeats (CRISPR) have been developed to detect SARSCoV-2 rapidly. Therefore, a systematic review and meta-analysis were performed to assess the diagnostic accuracy of CRISPR for detecting SARS-CoV-2 infection. @*Materials and Methods@#Studies published before August 2021 were retrieved from four databases, using the keywords “SARS-CoV-2” and “CRISPR.” Data were collected from these publications, and the sensitivity, specificity, negative likelihood ratio (NLR), positive likelihood ratio (PLR), and diagnostic odds ratio (DOR) were calculated. The summary receiver operating characteristic curve was plotted for analysis with MetaDiSc 1.4. The Stata 15.0 software was used to draw Deeks’ funnel plots to evaluate publication bias. @*Results@#We performed a pooled analysis of 38 independent studies shown in 30 publications. The reference standard was reverse transcription-quantitative PCR. The results indicated that the sensitivity of CRISPR-based methods for diagnosis was 0.94 (95% CI 0.93–0.95), the specificity was 0.98 (95% CI 0.97–0.99), the PLR was 34.03 (95% CI 20.81–55.66), the NLR was 0.08 (95% CI 0.06– 0.10), and the DOR was 575.74 (95% CI 382.36–866.95). The area under the curve was 0.9894. @*Conclusion@#Studies indicate that a diagnostic method based on CRISPR has high sensitivity and specificity. Therefore, this would be a potential diagnostic tool to improve the accuracy of SARS-CoV-2 detection.
Résumé
The occurrence development and progression of infectious diseases involves the two aspects: the immune response of both the pathogens and the hosts. At present, pathogen-based testing is the gold standard and the most commonly used method for the diagnosis of infectious diseases. The purpose of the immune system is to identify and eliminate invading pathogens. Testing based on host reactions has become an effective auxiliary means adjunct of traditional pathogen-based tests, with the potential to improve the accuracy and efficiency of diagnosis. The combined application of host-based tests and pathogen-based tests is a new field worth exploring.

Résumé
BACKGROUND@#Chronic obstructive pulmonary disease (COPD) is a common public health problem worldwide. Recent studies have reported that socioeconomic status (SES) is related to the incidence of COPD. This study aimed to investigate the association between SES and COPD among adults in Jiangsu province, China, and to determine the possible direct and indirect effects of SES on the morbidity of COPD.@*METHODS@#A cross-sectional study was conducted among adults aged 40 years and above between May and December of 2015 in Jiangsu province, China. Participants were selected using a multistage sampling approach. COPD, the outcome variable, was diagnosed by physicians based on spirometry, respiratory symptoms, and risk factors. Education, occupation, and monthly family average income (FAI) were used to separately indicate SES as the explanatory variable. Mixed-effects logistic regression models were introduced to calculate odds ratios (ORs) and 95% confidence intervals (CIs) for examining the SES-COPD relationship. A pathway analysis was conducted to further explore the pulmonary function impairment of patients with different SES.@*RESULTS@#The mean age of the 2421 participants was 56.63 ± 9.62 years. The prevalence of COPD was 11.8% (95% CI: 10.5%-13.1%) among the overall sample population. After adjustment for age, gender, residence, outdoor and indoor air pollution, body weight status, cigarette smoking, and potential study area-level clustering effects, educational attainment was negatively associated with COPD prevalence in men; white collars were at lower risk (OR: 0.60, 95% CI: 0.43-0.83) of experiencing COPD than blue collars; compared with those within the lower FAI subgroup, participants in the upper (OR: 0.68, 95% CI: 0.49-0.97) tertiles were less likely to experience COPD. Such negative associations between all these three SES indicators and COPD were significant among men only. Education, FAI, and occupation had direct or indirect effects on pulmonary function including post-bronchodilator forced expiratory volume in 1 s/forced vital capacity (FEV1/FVC), FEV1, FVC, and FEV1 percentage of predicted. Education, FAI, and occupation had indirect effects on pulmonary function indices of all participants mainly through smoking status, indoor air pollution, and outdoor air pollution. We also found that occupation could affect post-bronchodilator FEV1/FVC through body mass index.@*CONCLUSIONS@#Education, occupation, and FAI had an adverse relationship with COPD prevalence in Jiangsu province, China. SES has both direct and indirect associations with pulmonary function impairment. SES is of great significance for COPD morbidity. It is important that population-based COPD prevention strategies should be tailored for people with different SES.

Objective:To investigate the correlation between the location and volume of cerebral microbleeds (CMBs) and lacunar infarction (LI) in patients with cerebral small vessel disease (CSVD).Methods:Participants from the CSVD cohort in the Department of Neurology, Nanjing Drum Tower Hospital, the Affiliated Hospital of Medical School of Nanjing University from February 2017 to March 2019 were enrolled retrospectively. All participants underwent magnetic resonance imaging scans, standardized clinical assessment and diagnosis. AccuBrain, an automatic brain segmentation and quantification software developed by the Chinese University of Hong Kong, was used to quantitatively analyze the volume of CMBs and white matter hyperintensities (WMHs). Ordered multi-class logistic regression analysis was used to determine the independent influencing factors of LI, and then multiple linear regression analysis was used to investigate the correlation between the volume of deep or infratentorial CMBs (DI-CMBs) and the number of LI. Results:A total of 317 patients with CSVD were included in the analysis, including 214 (67.5%) in the non-LI group, 43 (13.6%) in the single LI group, and 60 (18.9%) in the multiple LI group. The comparison of the three groups showed that older age, male, smoking, drinking, history of previous stroke or transient ischemic attack (TIA), lower levels of high-density lipoprotein cholesterol, larger CMBs and WMHs volume, higher enlarged perivascular spaces (EPVS) grade might be the risk factors for LI. Ordinal multivariable logistic regression analysis showed that male (odds ratio [ OR] 2.058, 95% confidence interval [ CI] 1.084-3.909; P=0.027), previous stroke or TIA history ( OR 1.962, 95% CI 1.089-3.535; P=0.025), larger WMH volume ( OR 8.716, 95% CI 4.034-18.832; P<0.001), higher EPVS grade ( OR 1.915, 95% CI 1.292-2.839; P=0.001), larger DI-CMB volume ( OR 1.022, 95% CI 1.006-1.038; P=0.008) or more DI-CMB number ( OR 1.187, 95% CI 1.005-1.403; P=0.044) were the independent related factors of LI. Multiple linear regression analysis showed that there was a significant correlation between the volume of DI-CMB and the number of LI ( r=0.330, P<0.001). Conclusion:In patients with CSVD, there is a significant correlation between DI-CMBs and LI.

Objective: To explore the feasibility of the single-stage stent implantation following rotational atherectomy combined with transcatheter aortic valve replacement (TAVR) in treating patients with severe aortic stenosis(AS) and severe calcified coronary artery stenosis. Methods: Three patients who received single-stage stent implantation following rotational atherectomy combined with TAVR in Fuwai hospital from April to October 2019 were included in this retrospective analysis. Clinical and anatomical features (including echocardiography and aortic CT) of the patients were collected, efficacy and safety of this operation strategy were observed and 6 months follow up results were summarized. Results: Three patients (2 females, 66-80 years old) were included. The mean Society of Thoracic Surgeons (STS) risk score was 7.8%. The mean maximum velocity of aortic valve was 4.4 m/s, the mean transvalvular pressure gradient was 53.2 mmHg (1 mmHg=0.133 kPa), mean left ventricular ejection fraction (LVEF) was 48.6%. All three patients had severe calcified coronary artery stenosis: left anterior descending artery (LAD, n=2) and left main coronary artery (LM, n=1), requiring rotary grinding. The mean SYNTAX score was 20. All the procedures were performed through transfemoral access. After aortic valve crossing, all coronary lesions were successfully treated with stent implantation following rotational atherectomy, transfemoral TAVR was then immediately performed with a self-expandable Venus-A valve. One patient underwent"valve-in-valve"implantation due to the high-implantation position of the first valve. The procedures were completed without complications in all the three patients. The immediate effect was satisfactory. Echocardiography results showed that the mean maximum velocity of aortic valve was 2.1 m/s, mean gradient was 9.3 mmHg, and mean LVEF was 59% after the procedure. There was no death and revascularization during the 6 months follow-up. Conclusion: In patients with severe calcified coronary artery and severe AS with high risk of cardiac surgery, the single-stage stent implantation following rotational atherectomy combined with TAVR is feasible and results are satisfactory in this patient cohort.

Objective: To investigate the feasibility and efficacy of mini-incision with endoscope-assisted resection for bilateral congenital second branchial cleft fistula, and to report on a rare pedigree. Methods: The clinical data of 5 patients with bilateral congenital second branchial fistula admitted in Fujian Provincial Hospital from April 2007 to December 2018 were retrospectively reviewed, including 2 males and 3 females, aged from 3 to 31 years old. The surgical strateges and clinical experience of single mini-incision with endoscope-assisted fistulectomy were summarized, and a rare pedigree was reported. Results: In five patients, Case 1 to Case 4 were treated with bilateral endoscopic-assisted fistula high ligation with titanium clips and removal through a single small incision under general anesthesia. No obvious complications occurred after the operation. The patients were followed up for 40-164 months with no fistula recurrence. Case 5 gave up surgical resection and was followed up for 24 months with acute infection attack once. Case 2 and Case 4 came from the same family. In this family, 7 out of 31 members of four generations had second branchial cleft fistulas, of which 4 were bilateral and 3 were right. Pedigree analysis was consistent with autosomal dominant inheritance. No deafness, preauricular tag, external and middle ear deformity and kidney malformation were found in the family members. Conclusions: Bilateral congenital second branchial cleft fistula is rare. Surgical resection is the preferred treatment. Mini-incision with endoscopic-assisted fistula high ligation with titanium clip and resection has clear operative field, ideal cosmetic effect and definite curative effect.

Method:Following article retrieval from eight databases and data extraction by two reviewers, the methodological quality of the included trials was assessed and the outcome indicators were subjected to Meta-analysis using RevMan 5.3. Result:A total of 24 randomized controlled trials (RCTs) were included, involving 1 818 cases. Meta-analysis showed that Chinese medicinal formulae combined with western routine intervention was superior to the western routine intervention in improving the overall response rate (ORR) [relative risk (RR)=1.27, 95% confidence interval (CI) (1.21, 1.34), <inline-formula><alternatives><mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M5"><mml:mi>P</mml:mi></mml:math><graphic specific-use="big" xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="alternativeImage/27038DAF-2FF7-4d58-8001-0E6465A33408-M005.jpg"><?fx-imagestate width="2.28600001" height="2.62466669"?></graphic><graphic specific-use="small" xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="alternativeImage/27038DAF-2FF7-4d58-8001-0E6465A33408-M005c.jpg"><?fx-imagestate width="2.28600001" height="2.62466669"?></graphic></alternatives></inline-formula><0.000 01], the bacterial clearance rate [RR=1.49,95% CI (1.33, 1.66), <inline-formula><alternatives><mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M6"><mml:mi>P</mml:mi></mml:math><graphic specific-use="big" xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="alternativeImage/27038DAF-2FF7-4d58-8001-0E6465A33408-M006.jpg"><?fx-imagestate width="2.28600001" height="2.62466669"?></graphic><graphic specific-use="small" xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="alternativeImage/27038DAF-2FF7-4d58-8001-0E6465A33408-M006c.jpg"><?fx-imagestate width="2.28600001" height="2.62466669"?></graphic></alternatives></inline-formula><0.000 01], and the clinical pulmonary infection score (CPIS) [mean difference (MD)=-1.64, 95% CI (-1.87, -1.41), <inline-formula><alternatives><mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M7"><mml:mi>P</mml:mi></mml:math><graphic specific-use="big" xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="alternativeImage/27038DAF-2FF7-4d58-8001-0E6465A33408-M007.jpg"><?fx-imagestate width="2.28600001" height="2.62466669"?></graphic><graphic specific-use="small" xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="alternativeImage/27038DAF-2FF7-4d58-8001-0E6465A33408-M007c.jpg"><?fx-imagestate width="2.28600001" height="2.62466669"?></graphic></alternatives></inline-formula><0.000 01].

The comparison with the western routine intervention also revealed that Chinese medicinal formulae better improved the ORR and CPIS. Conclusion:According to the current research results, the Chinese medicinal formulae alone or combined with western routine intervention yielded more favorable clinical outcomes than western routine intervention in the treatment of antimicrobial-resistant pneumonia, without increasing the incidence of adverse events. Due to limited quality and quantity of the included RCTs, more high-quality trials are required to verify the above conclusions.
