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 systematically review thrombosis risk prediction models associated with peripherally inserted central venous catheter (PICC) in adults and provide a basis for the clinical application of these models and the development of subsequent models.Methods:Databases such as CNKI, Wanfang, VIP, PubMed, CINAHL, Web of Science, and Ovid were searched to collect studies on thrombosis risk prediction models related to adult PICC, covering all entries from the inception of the databases until December 31, 2022. Two researchers independently screened the literature, extracted data, and assessed the risk of bias.Results:Nineteen studies were included. D-dimer was the most common predictive factor; only five studies underwent external validation, and six studies evaluated model calibration. All included studies exhibited high risk of bias, primarily due to methodological deficiencies in model development and validation processes; the combined area under the receiver operating characteristic curve for nine models was 0.80 (95% Confidence Interval: 0.75-0.85) .Conclusions:Research on thrombosis risk prediction models related to adult PICC is still in its developmental stage. Most of the known models perform well with comprehensive and easily obtainable predictive factors, yet they exhibit methodological shortcomings. Future research should focus on improving the methodological quality and external validation during model development and validation processes.

Background: The treatment of trigeminal neuralgia remains a challenging issue.Stem cells from human exfoliated deciduous teeth (SHED) provide optimized therapy for chronic pain. This study aimed to investigate the mechanisms underlying the attenuation of trigeminal neuralgia by SHED. Methods: Trigeminal neuralgia was induced by chronic constriction injury of the infraorbital nerve. The mechanical threshold was assessed after model establishment and local SHED transplantation. Endoplasmic reticulum (ER) morphology and Caspase12 expression in trigeminal ganglion (TG) was evaluated as well. BiP expression was observed in PC12 cells induced by tunicamycin. Results: The local transplantation of SHED could relieve trigeminal neuralgia in rats.Further, transmission electron microscopy revealed swelling of the ER in rats with trigeminal neuralgia. Moreover, SHED inhibited the tunicamycin-induced up-regulated expression of BiP mRNA and protein in vitro. Additionally, SHED decreased the up-regulated expression of Caspase12 mRNA and protein in the TG of rats caused by trigeminal neuralgia after chronic constriction injury of the infraorbital nerve mode. Conclusions This findings demonstrated that SHED could alleviate pain by relieving ER stress which provide potential basic evidence for clinical pain treatment.

Objective To investigate the gene mutations of Chinese patients with pancreatic cancer in the coastal regions of Eastern China, and to provide a basis for individualized treatment. Methods A total of 40 patients who were admitted and diagnosed with malignant pancreatic tumor after surgical treatment in The Affiliated Hospital of Qingdao University, Qingdao Municipal Hospital, Yantaishan Hospital, and Yantai Sino-France Friendship Hospital from January 2017 to June 2019 were enrolled. Next-generation sequencing (NGS) was used to detect gene mutations in tumor tissue and somatic cells, and the map of gene mutations was plotted to analyze genomic alterations. The chi-square test or the Fisher's exact test was used for comparison of categorical data between groups. The Kaplan-Meier method was used to plot survival curves, and the log-rank test was used for comparison between groups. Results Among the 40 patients, 34 (85.0%) had pancreatic ductal adenocarcinoma, 3 (7.5%) had solid pseudopapillary neoplasm of the pancreas, 1 (2.5%) had pancreatic neuroendocrine tumor, and 2 (5.0%) had unclear typing. KRAS (80.0%, 32/40), TP53 (70.0%, 28/40), CDKN2A (32.5%, 13/40), SMAD4 (17.5%, 7/40), and AKT2 (17.5%, 7/40) were the most common mutations, and there was no significant difference in survival time between the patients with these five common gene mutations (all P > 0.05). Conclusion NGS technology can provide comprehensive and accurate information of genomic alterations and may provide novel potential biomarkers for the diagnosis and precise treatment of pancreatic cancer. The analysis of mutant genes also lays a foundation for the individualized treatment of pancreatic cancer.

Objective:To investigate the predictive value of serum anti-Mullerian hormone (AMH) combined with transvaginal color Doppler ultrasonography (vaginal color ultrasound) for ovarian reserve function in infertility patients.Methods:A total of 105 infertility patients diagnosed and treated in Dezhou People′s Hospital from January 2018 to October 2020 were selected as study subjects. Among them, 32 patients with less than 5 eggs obtained after the first treatment (low ovarian response) were included in group A, and 73 patients with 5 to 15 eggs obtained (normal ovarian response) were included in group B. Serum AMH levels were measured, antral follicle count (AFC), ovarian volume (OV), and ovarian stromal peak diastolic systolic velocity (PSV) were recorded by vaginal ultrasound. The levels of above index in A, B groups, patients aged > 35 years old, and those aged ≤35 years old were compared. Moreover, the correlation among serum AMH level and aged, ultrasonic parameters were analyzed. The efficacy of serum AMH level and AFC, OV and PSV in predicting low ovarian response was analyzed by receiver operating characteristic (ROC) curve.Results:The levels of serum AMH, AFC, OV and PSV in group A were lower than those in group B: (0.69 ± 0.28) μg/L vs. (1.43 ± 0.44) μg/L, (8.52 ± 2.29) eggs vs. (11.15 ± 2.56) eggs, (3.12 ± 0.70) cm 3 vs. (4.50 ± 1.31) cm 3, (8.80 ± 2.14) cm/s vs. (15.80 ± 4.43) cm/s, the differences were statistically significant ( P<0.05). The levels of serum AMH, AFC, OV and PSV in aged > 35 years old group were lower than those in aged ≤35 years old group: (0.64 ± 0.20) g/L vs. (1.71 ± 0.46) μg/L, (8.35 ± 2.68) eggs vs. (12.17 ± 2.79) eggs, (3.05 ± 0.78) cm 3 vs. (5.02 ± 1.26) cm 3, (9.01 ± 3.04) cm/s vs. (17.90 ± 4.19) cm/s, the differences were statistically significant ( P<0.05). Serum AMH level was negatively correlated with age ( r = -0.317, P<0.05), and positively correlated with AFC, OV and PSV ( r = 0.288, 0.326, 0.370, P<0.05). The sensitivity and specificity for the evaluation of low ovarian response by AMH+AFC+OV+PSV were 96.90% and 100.00% respectively. Conclusions:The sensitivity and specificity of serum AMH combined with vaginal color ultrasound for the evaluation of ovarian reserve function in infertility patients are both high.

ObjectiveTo compare the functional connectivity of brain networks in stroke patients with upper limb motor dysfunction during unilateral or bilateral upper limb movement using functional near-infrared spectroscopy (fNIRS). MethodsFrom April to June, 2021, 40 stroke patients with upper limb motor dysfunction in Department of Rehabilitation Medicine, Huashan Hospital, finished unilateral (affected) and bilateral upper limb movement. Eight-minute fNIRS data were collected before and after movement, and the functional activities and connectivity of prefrontal cortex (PFC), upper limb and hand functional area (H), primary sensory cortex (S1) were analyzed based on oxygenated hemoglobin. ResultsFunctional activities increased in affected H after unilateral task (t = -3.135, P < 0.05), while the functional connectivity increased between affected H and affected S1, affected H and unaffected S1, and affected S1 and unaffected S1 (|t| > 3.218, P < 0.05). There was no significant difference in the functional activities and connectivity of all the areas after bilateral upper limb task (|t| < 2.385, P > 0.05). The improvement of affected H was more after unilateral task than after bilateral upper limb task (t = 2.026, P < 0.05). ConclusionUnilateral affected upper limb training is more effective on functional activities and connectivity for corresponding brain regions than bilateral task.

Objective:To compare the prognosis of fluoroucil combined with cisplatin and paclitaxel combined with cisplatin regimens with concurrent radiotherapy in treatment of esophageal squamous cell carcinoma.Methods:A total of 120 patients with esophageal squamous cell carcinoma who were admitted to Anyang Tumor Hospital of Henan Province from December 2012 to November 2018 were randomly divided into group A and group B by using a random number generator. Group A was given cisplatin combined with 5-fluorouracil, and group B was given cisplatin combined with paclitaxel. Both groups had the same radiotherapy regimen, and both used intensity-modulated radiation therapy (IMRT). Completions of 50 Gy radiotherapy and at least one cycle of chemotherapy were considered to be in line with the plan. Survival data was analyzed in the term of intention-to-treat (ITT) and per-protocol (PP) set.Results:Of the 120 patients, 114 patients were treated and the adverse reactions could be evaluated, including 55 cases in group A and 59 cases in group B. The incidence of grade Ⅲ-Ⅳ leukopenia in group B was higher than that in group A [49.2% (29/59) vs. 25.5% (14/55)], and the difference was statistically significant ( χ2 = 6.805, P = 0.012), and there were no statistical differences in the other adverse reactions between the two groups (All P > 0.05). A total of 113 cases can be analyzed for survival. According to ITT analysis, the median progression-free survival (PFS) time in group A and group B was 28.0 months (95% CI 15.5-34.5 months) and 27.0 months (95% CI 17.0-41.0 months), the median overall survival (OS) time was 28.0 months (95% CI 15.8-34.2 months) and not reached, the differences were not statistically significant (both P > 0.05). According to PP analysis, the median PFS time in group A and group B was 28.0 months (95% CI 15.8-34.2 months) and 29.0 months (95% CI 14.9-45.1 months), the median OS time in group A and group B was 28.0 months (95% CI 3.7-52.3 months) and not reached, the differences were not statistically significant (both P > 0.05). Conclusions:The fluorouracil combined with cisplatin regimen and paclitaxel combined with cisplatin regimen with concurrent radiotherapy have similar PFS and OS time in treatment of esophageal squamous cell carcinoma, the adverse reactions are different, but they are all tolerable. In individualized clinical practice, the toxicities and costs of the two regimens can be comprehensively considered.
