Addressing the enduring challenge of evaluating traditional Chinese medicines (TCMs), the integrated evidence chain-based effectiveness evaluation of TCMs (Eff-iEC) has emerged. This paper explored its capacity through a demonstration study that evaluated the effectiveness evidence of six commonly used anti-hepatic fibrosis Chinese patent medicines (CPMs), including Biejiajian Pill (BP), Dahuang Zhechong Pill (DZP), Biejia Ruangan Compound (BRC), Fuzheng Huayu Capsule (FHC), Anluo Huaxian Pill (AHP), and Heluo Shugan Capsule (HSC), using both Eff-iEC and the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system. The recognition of these CPMs within the TCM academic community was also assessed through their inclusion in relevant medical documents. Results showed that the evidence of BRC and FHC received higher assessments in both Eff-iEC and GRADE system, while the assessments for others varied. Analysis of community recognition revealed that Eff-iEC more accurately reflects the clinical value of these CPMs, exhibiting superior evaluative capabilities. By breaking through the conventional pattern of TCMs effectiveness evaluation, Eff-iEC offers a novel epistemology that better aligns with the clinical realities and reasoning of TCMs, providing a coherent methodology for clinical decision-making, new drug evaluations, and health policy formulation.

OBJECTIVE: To explore the corrective strategies and effectiveness of osteotomy surgery for severe lower limb deformities in hypophosphatemic rickets. METHODS: A retrospective analysis was conducted on 29 patients with severe lower limb deformities of hypophosphatemic rickets who underwent surgical treatment between February 2012 and August 2024. There were 9 males and 20 females. The age ranged from 13 to 53 years, with an average of 24.6 years. All patients were deformities of both lower limbs, presenting as 24 cases of O-shaped legs, 2 cases of wind-blown deformities, and 3 cases of X-shaped legs. Based on the full-length films of both lower limbs in the standing position before operation, the osteotomy planes of the femur, tibia, and fibula were designed. Among them, if both the same-sided thigh and leg were deformed, staged surgeries of both lower limbs were selected. If only the thigh or leg were deformed, simultaneous surgeries of both lower limbs were selected. The femur deformity was corrected immediately after osteotomy at the deformed plane; the osteotomy fragment was temporarily controlled with an external fixator, which was removed after perform internal fixation with a steel plate. After fibular osteotomy, the Ilizarov frame or Taylor frame was installed on the tibia and fibula. The threaded rods were removed and then tibial osteotomy was performed on the deformed plane. Patients using the Taylor frame did not undergo deformity correction during operation. The external fixators were adjusted starting 7 days after operation to correct the varus, valgus, and rotational deformities of the lower limb. Patients using the Ilizarov frame corrected the rotational deformity of the tibia during operation. The external fixator was adjusted starting 7 days after operation to correct the varus and valgus deformities of the lower limb. During the treatment period, the patient could walk with partial weight-bearing on the operated limb with crutches. The external fixator was removed after the bone healed. Before operation and at last follow-up, the medial proximal tibial angle (MPTA), lateral distal tibial angle (LDTA), posterior proximal tibial angle (PPTA), anterior distal tibial angle (ADTA), anatomic lateral distal femoral angle (aLDFA), posterior distal femoral angle (PDFA), and mechanical axis deviation (MAD), lower limb rotation, limb length discrepancy (LLD) were measured. The self-made scoring criteria were adopted to evaluate the degree of lower limb deformity of the patients. RESULTS: All operations were successfully completed, and no complications such as nerve or vascular injury occurred. The adjustment time of the external fixator of the lower limb after operation was 28-46 days, with an average of 37.4 days. The wearing time of the external fixator ranged from 134 to 398 days, with an average of 181.5 days. Mild pin tract infections occurred in 2 limbs. The osteofascial compartment syndrome occurred in 1 limb after operation. No complications related to orthopedic adjustment of the external fixator occurred in other patients. All patients were followed up 6-56 months, with an average of 28.2 months. At last follow-up, full-length films of both lower limbs in the standing position showed that the coronal mechanical axes of the lower limbs of all patients returned to the normal. At last follow-up, MPTA, LDTA, PPTA, aLDFA, PDFA, MAD, lower limb rotation, LLD, and the score of lower limb deformity significantly improved when compared with those before operation ( P<0.05). There was no significant difference in ADTA between pre- and post-operation ( P>0.05). The degree of lower limb deformity were rated as moderate in 2 cases and poor in 27 cases before operation and as excellent in 7 cases, good in 18 cases, and moderate in 4 cases at last follow-up, with an excellent and good rate of 86.2%. CONCLUSION For severe lower limb deformities in hypophosphatemic rickets, immediate correction of deformities with femoral osteotomy and internal plate fixation, as well as gradually correction of deformities with tibiofibular osteotomy and circular external fixation (Ilizarov frame or Taylor frame), have satisfactory therapeutic effects.

Objective:To investigate the clinical features of nontuberculous mycobacteria (NTM) disease patients with positive anti-interferon γ (IFN-γ) autoantibody.Methods:Forty-three adult human immunodeficiency virus-uninfected patients with NTM disease hospitalized in Huashan Hospital, Fudan University and Jing′an Branch, Huashan Hospital, Fudan University from July 2021 to August 2023 were included. Clinical data and NTM strain information of the patients were collected. The plasma levels of anti-IFN-γ autoantibodies were detected by enzyme-linked immunosorbent assay, and the patients were divided into antibody positive group and antibody negative group. The clinical characteristics and laboratory examination results between the two groups were compared. The independent sample t test, Mann-Whitney U test and chi-square test were used for statistical analysis. Multivariate logistic regression analysis was used to determine the correlation factors of positive anti-IFN-γ autoantibodies. Results:Among the 43 patients, 13 cases (30.2%) were positive for anti-IFN-γ autoantibodies and 30 cases (69.8%) were negative. The proportions of patients with NTM disseminated infection (9/13 vs 30.0%(9/30))and combined bacterial infection (5/13 vs 6.7%(2/30)) in antibody positive group were both higher than those in antibody negative group, and the differences were both statistically significant ( χ2=5.74 and 6.73, respectively, both P<0.05). The white blood cell count, platelet count, the proportion of platelet count >350×10 9/L of antibody positive patients were all higher than those of antibody negative group, while the white sphere ratio was lower than that of antibody negative group, with statistical significance ( t=2.42, 3.02, χ2=9.77 and t=3.66, respectively, all P<0.05). Erythrocyte sedimentation rate, C-reactive protein, procalcitonin, globulin, immunoglobulin G, immunoglobulin A and immunoglobulin M in antibody positive patients were all higher than those in antibody negative group, and the differences were all statistically significant ( U=99.50, 112.00, 115.50, 61.50, 76.50, 99.00 and 83.00, respectively, all P<0.05). Mycobacterium abscessus complex (seven cases and 11 cases, respectively) and Mycobacterium avium complex (five cases and 13 cases, respectively) were the main isolated strains in antibody positive and antibody negative patients. Multivariate logistic regression analysis showed that combined with bacterial infection (odds ratio ( OR)=21.83, 95% confidence interval ( CI) 1.94 to 245.71), NTM disseminated infection ( OR=7.64, 95% CI 1.10 to 53.26), platelet count>350×10 9/L ( OR=14.31, 95% CI 1.91 to 107.04) were risk factors for anti-IFN-γ autoantibodies positive (all P<0.05). Conclusions:Patients with positive anti-IFN-γ autoantibodies have higher probability of having elevated levels of systemic inflammation. Anti-IFN-γ autoantibody test is recommended for patients with NTM disease who present with co-bacterial infection, NTM disseminated infection, or elevated platelet count (>350×10 9/L).

Objective:To investigate the effect of nuclear factor-erythroid 2-related factor 2 (Nrf2) gene on the proliferation and apoptosis of colorectal adenocarcinoma cells in vitro, and the role of Nrf2 gene in regulation of epithelial-mesenchymal transition (EMT) pathway.Methods:Three Nrf2 small interfering RNA (siRNA) sequences were designed and synthesized, namely siRNA-223, siRNA-538 and siRNA-756, and the unrelated sequences were designed and synthesized. The plasmids carrying various siRNA sequences of Nrf2 were constructed, and the plasmids carrying siRNA sequences and the plasmids carrying unrelated sequences were transfected into human colorectal adenocarcinoma Caco-2 cells, namely interference group and empty vector group, respectively. Additionally, Caco-2 cells without any treatment were used as the control group. Real-time fluorescence quantitative polymerase chain reaction (RT-qPCR) and Western blotting (WB) methods were used to detect the relative expression of Nrf2 gene in transcription and translation levels in each group of cells, in order to verify the interference effect of Nrf2; the siRNA with the best interference effect was selected for subsequent experiments. CCK-8 method was used to detect the proliferation ability of each group of cells (expressed as absorbance value); RT-qPCR was used to detect the relative expression of EMT pathway-related factors [vimentin (Vim), N-cadherin (N-cad) and E-cadherin (E-cad)] in transcription level in each group of cells; WB method was used to detect the expression of pro-apoptotic protein Bax in each group of cells.Results:The results of RT-qPCR and WB methods showed that compared with the control group and the empty group, the relative expression of Nrf2 gene in transcription and translation levels in Caco-2 cells of the siRNA-756 interference group were the lowest, and the differences were statistically significant (all P < 0.05). The CCK-8 results showed that the absorbance values of Caco-2 cells in the control group, empty group and siRNA-756 interference group after 48 hours of culture were (100±5)%, (94±4)% and (82±5)%, respectively; compared with the control group and the empty group, the siRNA-756 interference group had lower absorbance value, and the differences were statistically significant (all P < 0.05). The results of RT-qPCR method showed that the relative expression of Vim and N-cad in transcription level in the siRNA-756 interference group were higher than those in the control group and the empty vector group, and the differences were statistically significant (all P < 0.05); the relative expression of E-cad in transcription level was lower than those in the control group and the empty vector group, and the differences were statistically significant (both P < 0.05). The results of WB method showed that the relative expression of Bax protein in the siRNA-756 interference group was higher than that in the control group, and the difference was statistically significant ( P < 0.05). Conclusions:Interference with Nrf2 expression in vitro can weaken the proliferation and anti-apoptotic abilities of human colorectal adenocarcinoma Caco-2 cells. The mechanism may be that Nrf2 regulates the expression of Vim, N-cad and E-Cad in the EMT pathway to enhance the EMT ability of tumor cells.

Objective:To analyze the selection of outcome indicators for randomized controlled trials (RCT) on exercise rehabilitation in patients with atrial fibrillation (AF), promote the construction of the core outcome set and provide reference for the research design of subsequent RCT.Methods:The RCT literature related to exercise rehabilitation of patients with atrial fibrillation was systematically searched from CNKI, Wanfang, VIP, PubMed, Web of Science, Embase and Cochrane Library databases, and the search period was from establishment of the databases until July 31, 2023. After literature screening, Cochrane Risk of Bias Assessment Tool was used for quality evaluation, information extraction, classification of outcome indicators, frequency of use statistics, analysis and extraction of current shortcomings in the selection of outcome indicators, and corresponding suggestions were proposed.Results:A total of 32 articles were included, and 19 RCT were evaluated twice for outcome measures. The number of outcome measures ranged from 2 to 17, with 10 RCT setting outcome measures according to primary and secondary criteria and 6 RCT setting safety outcome measures. A total of 96 outcome indicators were extracted in this study, total 266 frequency, which could be divided into 4 categories, such as safety evaluation (18 times), clinical response (75 times), patient-reported outcomes (68 times) and laboratory and other examination (105 times) .Conclusions:Existing RCT outcome indicators of exercise rehabilitation in patients with atrial fibrillation emphasize the changes in subjective feelings and objective indicators of individuals, covering four aspects such as the physical condition, exercise ability, quality of life and psychological status of individuals. However, there is a lack of uniform standards and the safety evaluation indicators are fewer. The categories of exercise rehabilitation indicators for atrial fibrillation patients extracted in this paper can provide a reference for the design of future RCT studies and promote the generation of higher quality evidence-based medical evidence.

A method capable of retinal vessel segmentation and three-dimensional(3D)reconstruction is proposed for the early diagnosis of diabetic retinopathy.The 3D reconstruction can avoid the misjudgments of blood vessel length,curvature and branch angle after segmentation,which will affect the early diagnosis.IAAnet algorithm for retinal image segmentation combines traditional Unet with Inception V3,atrous spatial pyramid pooling and AttentionGates to reduce information loss and avoid over-fitting,thereby improving the network's ability to extract features.The projection reconstruction method is used to restore the 3D information of blood vessels,and supports the adjustments of brightness and contrast,so that doctors can better observe the real state of blood vessels.The proposed algorithm has an accuracy,recall rate,F1 score,intersection over union and area under ROC curve of 97.68%,96.07%,97.26%,92.79%and 94.00%,respectively.Compared with other networks,IAAnet algorithm exhibits higher segmentation accuracy,and can obtain more vascular information in 3D image after 3D projection reconstruction to assist in the early diagnosis.

OBJECTIVE: To investigate the effectiveness of single Taylor external fixator combined with biplanar osteotomy on correction of tibial multiplanar deformities. METHODS: Between October 2016 and December 2021, 11 patients with tibial multiplanar deformities (20 sides) were treated with single Taylor external fixator and biplanar osteotomy. Of them, 4 were male and 7 were female; the average age ranged from 13 to 33 years (mean, 21.9 years). Diagnosis included rickets severe genu varum deformity (7 cases, 14 sides), rickets severe genu valgum deformity (2 cases, 4 sides), multiple osteochondromatosis calf deformity (1 case, 1 side), neurofibromatosis medial lower leg anterior arch deformity with short of leg (1 case, 1 side). After fibular osteotomy and tibial multiplanar osteotomy, a Taylor external fixator was installed. After operation, the deformities were corrected successively and fixed completely. The osteotomy healed, then the external fixator was removed. Before operation and at 12 months after operation, the full-length X-ray films were taken. The leg-length discrepancy, medial proximal tibial angle (MPTA), lateral distal tibial angle (LDTA), posterior proximal tibial angle (PPTA), anterior distal tibial angle (ADTA), and tibial rotation angle were measured. The degree of lower limb deformity was scored with reference to a customized tibial mechanical axis scoring table. RESULTS: Osteotomy was successfully completed without neurovascular injury and other complications. The external fixator was adjusted for 28-46 days, with an average of 37 days, and the external fixator was worn for 136-292 days, with an average of 169 days. Mild needle infection during the fixation period occurred in 3 sides, refracture at the distal tibial osteotomy in 1 side after removing the external fixator, and nonunion of the distal fibular osteotomy in 1 side. All patients were followed up 369-397 days (mean, 375 days). At 12 months after operation, the lower limb discrepancy decreased, but there was no significant difference ( P>0.05). MPTA, LDTA, PPTA, ADTA, and tibial rotation angle improved, and the differences in LDTA, ADTA, and tibial rotation angle were significant ( P<0.05). The score of lower limb deformity was significantly higher than that before operation ( P<0.05), and the results were excellent in 9 sides, good in 8 sides, fair in 3 sides, with the excellent and good rate of 85%. CONCLUSION Single Taylor external fixator combined with biplanar osteotomy is effective in the correction of tibial multiplanar deformities.

Non-small cell lung cancer (NSCLC) is the most common pathological type of lung cancer. The systemic antitumor therapy of advanced NSCLC has undergone renovations of chemotherapy, targeted therapy and immunotherapy, which results in greatly improved survival for patients with advanced NSCLC. Immune checkpoint inhibitors (ICIs), especially targeting programmed cell death protein 1 (PD-1)/programmed death-ligand 1 (PD-L1), has changed the treatment paradigm of NSCLC. ICIs have become the standard treatment for advanced NSCLC without epidermal growth factor receptor(EGFR) mutation or anaplastic lymphomakinase(ALK) translocation in the first- or second-line setting, and for locally advanced NSCLC following concurrent radiotherapy and chemotherapy. ICIs are also promising in adjuvant/neoadjuvant therapy. More and more ICIs have been approved domestically for the treatment of NSCLC. Led by the NSCLC expert committee of Chinese Society of Clinical Oncology (CSCO), this consensus was developed and updated based on thoroughly reviewing domestic and foreign literatures, clinical trial data, systematic reviews, experts' discussion and the consensus(2019 version). This consensus will aid domestic clinicians in the treatment of NSCLC with ICIs.
