Cervical spine health issues not only seriously affect patients' quality of life but also impose a heavy burden on the social healthcare system. Existing guidelines lack sufficient clinical guidance on lifestyle and work habits, such as exercise, posture, daily routine, and diet, making it difficult to meet practical needs. To address this, relying on the China Association of Chinese Medicine, Wangjing Hospital of China Academy of Chinese Medical Sciences took the lead and joined hands with more than ten institutions to form a multidisciplinary guideline development group. For the first time, the group developed the Guidelines for Cervical Spine Health Intervention based on evidence-based medicine methods, strictly following the standardized procedures outlined in the World Health Organization Handbook for Guideline Development and the Guiding Principles for the Formulation/Revision of Clinical Practice Guidelines in China (2022 Edition). This proposal systematically explains the methods and steps for developing the guideline, aiming to make the guideline development process scientific, standardized, and transparent.

PURPOSE: Lateral patellar compression syndrome (LPCS) is characterized by a persistent abnormally high stress exerted on the lateral articular surface of the patella due to lateral patellar tilt without dislocation and lateral retinaculum contracture, leading to anterior knee pain. The purpose of this study is to evaluate the efficacy and prognosis of lateral retinaculum release (LRR) combined with chondroplasty in the treatment of LPCS. METHODS: This retrospective study evaluated 40 patients who underwent LRR combined with chondroplasty for LPCS between 2020 and 2021. The assessment included improvement in postoperative tenderness and knee joint function. Patients were evaluated using the Lysholm, Tegner, and International Knee Documentation Committee 2000 scoring systems, as well as the visual analog scale, both preoperatively and postoperatively, with the paired comparisons analyzed using a t-test. Additionally, intraoperative observations were made regarding knee joint lesions, including cartilage damage and osteophyte formation, with analysis by the Chi-square test. RESULTS: The visual analog scale score for tenderness showed a significant decrease after surgery (p < 0.001). Evaluation of knee joint function also indicated significant improvements, as demonstrated by increased Lysholm, Tegner, and International Knee Documentation Committee 2000 scores postoperatively (p < 0.001, p = 0.011, p < 0.001, respectively). Furthermore, all LPCS patients included in the study presented with cartilage injuries and osteophyte formation. Significant differences were noted in the incidence of cartilage damage and osteophyte formation at different locations within the knee among patients with LPCS. CONCLUSION LRR combined with chondroplasty is an effective surgical approach for treating patients with LPCS, with satisfactory recovery observed at the 1-year follow-up. Additionally, the incidence of cartilage damage and osteophyte formation in LPCS patients varies significantly depending on the specific location within the knee joint.

Traditional Chinese medicine(TCM) processing is a unique and highly distinctive pharmaceutical technology in China. Utilizing modern scientific methods to elucidate the connotations of traditional processing theory and its effects is expected to facilitate the inheritance, development, innovation, and enhancement of TCM processing, and lead to more original research outcomes in the field of TCM. The breakthrough in TCM processing lies in the study of its underlying principles, and analyzing these principles involves researching the transformation mechanisms of chemical components and the biological effect mechanisms of the transformed components. This paper proposed the concept of "TCM processing chemical biology"(TCMPCB) for the first time. Under the guidance of TCM theory, the active components transformed during TCM processing were used as chemical tools to study their targets and molecular regulatory mechanisms, aiming to clarify the scientific principles by which TCM processing affected biological effects in the organism. The research findings also provided new directions for discovering novel active components, new lead compounds, creating new decoction pieces, and developing new TCM drugs. This paper provided a detailed introduction to the background, definition, research content, research ideas, research methods, and prospects of TCMPCB, with the aim of offering new research perspectives for analyzing the principles of TCM processing and providing new pathways for achieving the "four new and eight transformations" in TCM processing.

OBJECTIVE: To examine the mechanistic of organochlorine-associated changes in lung function. METHODS: This study investigated 76 healthy older adults in Jinan, Shandong Province, over a five-month period. Personal exposure to organochlorines was quantified using wearable passive samplers, while inflammatory factors and thyroid hormones were analyzed from blood samples. Participants' lung function was evaluated. After stratifying participants according to their thyroid hormone levels, we analyzed the differential effects of organochlorine exposure on lung function and inflammatory factors across the low and high thyroid hormone groups. Mediation analysis was further conducted to elucidate the relationships among organochlorine exposures, inflammatory factors, and lung function. RESULTS: Bis (2-chloro-1-methylethyl) ether (BCIE), was negatively associated with forced vital capacity (FVC, -2.05%, 95% CI: -3.11% to -0.97%), and associated with changes in inflammatory factors such as interleukin (IL)-2, IL-7, IL-8, and IL-13 in the low thyroid hormone group. The mediation analysis indicated a mediating effect of IL-2 (15.63%, 95% CI: 0.91% to 44.64%) and IL-13 (13.94%, 95% CI: 0.52% to 41.07%) in the association between BCIE exposure and FVC. CONCLUSION Lung function and inflammatory factors exhibited an increased sensitivity to organochlorine exposure at lower thyroid hormone levels, with inflammatory factors potentially mediating the adverse effects of organochlorines on lung function.

Glutamine provides carbon and nitrogen to support the proliferation of cancer cells. However, the precise reason why cancer cells are particularly dependent on glutamine remains unclear. In this study, we report that glutamine modulates the tumor suppressor F-box and WD repeat domain-containing 7 (FBW7) to promote cancer cell proliferation and survival. Specifically, lysine 604 (K604) in the sixth of the 7 substrate-recruiting WD repeats of FBW7 undergoes glutaminylation (Gln-K604) by glutaminyl tRNA synthetase. Gln-K604 inhibits SCFFBW7-mediated degradation of c-Myc and Mcl-1, enhances glutamine utilization, and stimulates nucleotide and DNA biosynthesis through the activation of c-Myc. Additionally, Gln-K604 promotes resistance to apoptosis by activating Mcl-1. In contrast, SIRT1 deglutaminylates Gln-K604, thereby reversing its effects. Cancer cells lacking Gln-K604 exhibit overexpression of c-Myc and Mcl-1 and display resistance to chemotherapy-induced apoptosis. Silencing both c-MYC and MCL-1 in these cells sensitizes them to chemotherapy. These findings indicate that the glutamine-mediated signal via Gln-K604 is a key driver of cancer progression and suggest potential strategies for targeted cancer therapies based on varying Gln-K604 status.

Objective:To empirically assess the effectiveness of the payment reform for traditional Chinese medicine(TCM)advantageous diseases and provide a scientific foundation for optimizing the payment method in TCM.Methods:Data on TCM cases of patients discharged from January 2022 to August 2023 were collected from all TCM hospitals piloting the payment reform for TCM advantageous diseases in city S.Cases were screened according to the TCM disease codes of the 22 pilot diseases.An interrupted time series model was constructed based on the time point of reform implementation to analyze the effect of the reform in the pilot hospitals vertically.Additionally,the model compared the differences in effect between second-and third-tier TCM hospitals horizontally.Results:In secondary hospitals,the bed day cost increased by 219.05 yuan during the reform period,and both the average hospitalization cost per admission and average TCM cost per admission showed an upward trend after the reform.In tertiary hospitals,the average out-of-pocket cost per admission and bed day cost decreased following the reform,while the average length of hospital stay and average TCM cost per admission increased.These trends were more pronounced in comparison to secondary hospitals.Conclusion:The reform effects varied across different hospital levels.It is recommended to dynamically adjust the payment standards for disease categories,establish differentiated evaluation metrics,and continuously monitor the long-term outcomes of the reform to further optimize the payment methods for TCM advantageous diseases.

Objective:To compare the treatment effect of endoscopic retrograde cholangiopancreatography/endoscopic sphincterotomy plus laparoscopic cholecystectomy (ERCP/EST+ LC) and laparoscopic cholecystectomy plus laparoscopic common bile duct exploration (LC+ LCBDE) for patients with choledocholithiasis combined with gallbladder stones.Methods:Clinical data of 172 patients with choledocholithiasis combined with gallbladder stones treated in Heze Municipal Hospital from March 2018 to March 2021 were retrospectilvely analyzed, including 78 males and 94 females, aged (66.88±9.72) years. According to surgical method, patients were divided into the ERCP/EST+ LC group ( n=86) and LC+ LCBDE group ( n=86). The initial clearance rate of choledochal stones, operation time, intraoperative blood loss and postoperative complications were compared between the groups. Results:The initial clearance rate of the choledochal stones of the ERCP/EST+ LC group is 76.5%(13/17), lower than 96.3%(26/27) of LC+ LCBDE group when the diameter of stones was over 1.2 cm ( χ2=4.07, P=0.044). When the number of choledochal stones were more than 3, the initial clearance rate of the ERCP/EST+ LC group is 78.9%(15/19), lower than that of the LC+ LCBDE group [96.7%(29/30), χ2=3.99, P=0.046]. The operation time of LC+ LCBDE group was longer than that of ERCP/EST+ LC group [(129.07±19.33)min vs. (101.86±27.48)min, t=7.51, P<0.001]. The median intraoperative blood loss of LC+ LCBDE group and ERCP/EST+ LC group was 25.0 (20.0, 30.0) ml and 13.0 (10.0, 15.0) ml, respectively ( Z=916.00, P<0.001). The age, gender, maximum diameter of stones, number of stones, preoperative common bile duct diameter, surgical success rate, postoperative hospital stay, total stone clearance rate, and complication rate were comparable between the groups (all P>0.05). Conclusion:Both LC+ LCBDE and ERCP/EST+ LC are safe and feasible for choledocholithiasis combined with cholecystolithiasis. When the maximum diameter of choledochal stones is ≥1.2 cm or the number of choledochal stones is ≥3, LC+ LCBDE should be favored. When patient is in poor general condition, ERCP/EST+ LC might be more feasible.
