This paper systematically reviewed the concept of authentication studies on traditional Chinese medicine （TCM） classics and the research achievements of scholars across historical and contemporary periods. We categorized the authentication studies on TCM classics into four types， including work-oriented authentication research， metho-dological studies on authentication， extended authentication research， and single-book authentication. Multiple methods were applied comprehensively， including investigating bibliographic documents of successive dynasties， analyzing the academic contents of medical books， studying the textual characteristics of medical books， examining the cited references in medical books， verifying the biographies of authors， and analyzing the interpolations and accretions in medical books， to distinguish the authenticity of TCM classics. The academic value of authenticity identification of TCM classics is concluded in three aspects，i.e. it serves as an important means to distinguish authenticity from falsehood in TCM classics， an important guarantee for inheriting the essence of TCM literature， and a key to unlocking the academic treasure trove of TCM classics and achieving inheritance-based innovation， which will lay a solid documentary foundation for constructing identification methodologies and standardized systems.

Objective: To develop QingNangTCM, a specialized large language model (LLM) tailored for expert-level traditional Chinese medicine (TCM) question-answering and clinical reasoning, addressing the scarcity of domain-specific corpora and specialized alignment. Methods: We constructed QnTCM_Dataset, a corpus of 100 000 entries, by integrating data from ShenNong_TCM_Dataset and SymMap v2.0, and synthesizing additional samples via retrieval-augmented generation (RAG) and persona-driven generation. The dataset comprehensively covers diagnostic inquiries, prescriptions, and herbal knowledge. Utilizing P-Tuning v2, we fine-tuned the GLM-4-9B-Chat backbone to develop QingNangTCM. A multi-dimensional evaluation framework, assessing accuracy, coverage, consistency, safety, professionalism, and fluency, was established using metrics such as bilingual evaluation understudy (BLEU), recall-oriented understudy for gisting evaluation (ROUGE), metric for evaluation of translation with explicit ordering (METEOR), and LLM-as-a-Judge with expert review. Qualitative analysis was conducted across four simulated clinical scenarios: symptom analysis, disease treatment, herb inquiry, and failure cases. Baseline models included GLM-4-9B-Chat, DeepSeek-V2, HuatuoGPT-II (7B), and GLM-4-9B-Chat (freeze-tuning). Results: QingNangTCM achieved the highest scores in BLEU-1/2/3/4 (0.425/0.298/0.137/0.064), ROUGE-1/2 (0.368/0.157), and METEOR (0.218), demonstrating a balanced and superior normalized performance profile of 0.900 across the dimensions of accuracy, coverage, and consistency. Although its ROUGE-L score (0.299) was lower than that of HuatuoGPT-II (7B) (0.351), it significantly outperformed domain-specific models in expert-validated win rates for professionalism (86%) and safety (73%). Qualitative analysis confirmed that the model strictly adheres to the “symptom-syndrome-pathogenesis-treatment” reasoning chain, though occasional misclassifications and hallucinations persisted when dealing with rare medicinal materials and uncommon syndromes. Conclusion Combining domain-specific corpus construction with parameter-efficient prompt tuning enhances the reasoning behavior and domain adaptation of LLMs for TCM-related tasks. This work provides a technical framework for the digital organization and intelligent utilization of TCM knowledge, with potential value for supporting diagnostic reasoning and medical education.

OBJECTIVE To explore the efficacy and safety of different doses of bupivacaine liposome （referred to as “LB”） in posterior quadratus lumborum block （QLB） for postoperative analgesia in patients undergoing cesarean section （CS）. METHODS In prospective research method， a total of 168 patients undergoing CS admitted to Chongzhou Maternal and Child Health Hospital from June to December 2024 were randomly divided into LB1 group， LB2 group， and LB3 group （LB of 199， 133 and 67 mg， respectively） according to the random number sorting method， with 56 cases in each group. All patients underwent CS after combined spinal-epidural anesthesia， and received patient-controlled intravenous analgesia and bilateral posterior QLB with different doses of LB after the operation. Visual analogue scale score， Ramsay sedation score， the presence of postoperative block planes and muscle strength classification were observed in the three groups of patients at 6， 12， 24， 48 and 72 hours after the operation. The time of the first compression of the analgesic pump， the dosage of sufentanil and butorphanol within 72 hours after surgery， the number of compressions of the analgesic pump， the analgesic rescue rate， the time of initiating lactation， the score of neonatal behavioral neurological assessment （NBNA）， the time of postoperative exhaust， the indwelling time of urinary catheter， the length of hospital stay， and the total satisfaction at 72 hours after surgery were compared. The occurrence of adverse reactions within 72 hours after the operation was recorded. RESULTS The resting and motor pain scores， the dosage of sufentanil and butorphanol within 72 hours after surgery， the number of compressions of the analgesic pump， the analgesic rescue rate， and the time of initiating lactation at 6， 12， 24， 48 and 72 hours after surgery in the LB1 group and the LB2 group were significantly lower or shorter than those in the LB3 group（P＜0.05）. The proportion of postoperative block planes at 24， 48 and 72 hours after surgery， the time of the first compression of the analgesic pump and the total satisfaction in the LB1 group and the LB2 group were significantly higher or longer than those in the LB3 group（P＜0.05）. The proportion of patients with muscle strength≤grade 3 at 6 hours after surgery in the LB1 group was significantly higher than that in the LB2 and the LB3 groups （P＜0.05）. There were no statistically significant differences in the Ramsay sedation scores at each time point after surgery， NBNA scores， postoperative exhaust time， urinary catheter indwelling time， the length of hospital stay， as well as the occurrence of adverse reactions among the 3 groups （P＞0.05）. CONCLUSIONS Compared with 67 mg of LB， 199 mg and 133 mg of LB can improve the postoperative analgesic effect and total satisfaction of CS patients undergoing posterior QLB， reduce the use of postoperative analgesic drugs， and shorten the time to start lactation. Compared with 199 mg and 133 mg of LB， 67 mg of LB has a smaller impact on the motor function of CS patients. All three doses of LB had no significant effect on the neurobehavioral abilities of newborns, and demonstrated comparable sedative efficacy and safety.

Objective: To understand current state of physical health levels of first year students in different body mass index (BMI) categories in Ningxia universities, and to explore the correlation between BMI and physical fitness index (PFI), so as to provide a reference for enhancing physical health levels of university students. Methods: In November 2024, physical fitness test data from 16 631 first year students across four universities in Yinchuan City, Ningxia from 2019 to 2023 were collected by adopting convenience and stratified cluster random sampling methods. The PFI was calculated using the Z score of the physical fitness test results, and a nonlinear quadratic model was established via least squares regression to examine the relationship between BMI and PFI among university students. Results: The BMI for males was (21.69±3.53)kg/m 2, while for females was (20.78±2.94)kg/m 2. The composite score for males physical fitness (69.86±9.25) was lower than that for females (72.24± 8.15 ), with a statistically significant difference ( t =-17.54, P <0.01). Moreover, the failure rates of various physical fitness indicators (vital capacity, sit and reach, standing long jump, pull ups/1 minute sit ups, 1 000 m/800 m run) were higher among males than females ( χ 2=103.48, 72.45, 14.38, 5 134.85, 188.89, all P <0.01). Comparisons across BMI categories revealed that among males, the normal weight group outperformed other groups in the 50 m sprint, standing long jump, 1 000 m sprint, composite score, and PFI ( F =89.17, 113.90, 179.02, 573.35, 593.08); among female students, the normal weight group outperformed other groups in the 50 m sprint, sit and reach, 800 m run, composite score, and PFI ( F =10.67, 19.58 , 96.45, 294.05, 183.45) (all P <0.01). The relationship between BMI and PFI among first year students exhibited a parabolic change trend, students with a moderate BMI demonstrated higher PFI, and as BMI increased, PFI decreased (all P <0.01). Conclusions The physical health level of male students in Ningxia universities is lower than that of female students. There is a correlation between BMI classification and PFI. Tailored intervention measures should be implemented according to the physical characteristics of students across different genders and BMI classifications to enhance university students physical health.

OBJECTIVE: To determine the impact of the lower limb weight bearing line ratio (WBLR) on motor function recovery after high tibial osteotomy (HTO). METHODS: A retrospective analysis was conducted on 55 patients with unilateral compartment knee osteoarthritis who underwent open-wedge HTO between August 2020 and October 2023 and met the selection criteria. Based on the postoperative Lysholm score, patients were divided into two groups: the good knee function group (Lysholm score≥90, group A) and the poor knee function group (Lysholm score<90, group B). Lysholm score, American Knee Society (AKS) score, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, and visual analogue scale (VAS) score for pain were compared between the two groups. Univariate analysis was performed on baseline data including gender, age, body mass index (BMI), affected side, disease duration, Kellgren-Lawrence grade, and radiographic parameters [preoperative and postoperative medial proximal tibial angle, lateral distal femoral angle, femoral-tibial angle, hip-knee-ankle angle (HKA), WBLR, posterior tibial slope angle, and joint line convergence angle] to identify factors influencing functional recovery. Multivariate logistic regression analysis was further used to identify independent factors. Additionally, receiver operating characteristic (ROC) curve analysis was employed to determine the optimal cut-off value of postoperative WBLR for predicting motor function recovery, and the area under curve (AUC) was calculated to assess diagnostic performance. RESULTS: All 55 patients were followed up 10-14 months (mean, 11.8 months). According to the postoperative Lysholm score, there were 30 patients in group A and 25 in group B. All postoperative clinical scores in group A were significantly better than those in group B ( P<0.05). Univariate analysis indicated that age, BMI, postoperative HKA, and postoperative WBLR were influencing factors for motor function recovery ( P<0.1). Further multivariate logistic regression analysis identified a postoperative WBLR≤55.5% as an independent factor influencing motor function recovery ( P<0.05). ROC curve analysis yielded an AUC of 0.788 and determined the optimal postoperative WBLR cut-off value for predicting motor function recovery to be 55.5% ( P<0.001). CONCLUSION A postoperative WBLR of 55.5% is associated with optimal motor function recovery after HTO.
