OBJECTIVE To explore the pharmacokinetic characteristics of 3 blood-absorbed components of Xiangshao sanjie oral liquid in rats with hyperplasia of mammary gland （HMG）. METHODS Female SD rats were divided into control group and HMG group according to body weight， with 6 rats in each group. The HMG group was given estrogen+progesterone to construct HMG model. After modeling， two groups were given 1.485 g/kg of Xiangshao sanjie oral liquid （calculated by crude drug） intragastrically， once a day， for 7 consecutive days. Blood samples were collected before the first administration （0 h）， and at 5， 15， 30 minutes and 1， 2， 4， 8， 12， 24 hours after the last administration， respectively. Using chlorzoxazone as the internal standard， the plasma concentrations of ferulic acid， paeoniflorin and rosmarinic acid in rats were detected by UPLC-Q/TOF-MS. The pharmacokinetic parameters [area under the drug time curve （AUC0－24 h， AUC0－∞）， mean residence time （MRT0－∞）， half-life （t1/2）， peak time （tmax）， peak concentration （cmax）] were calculated by the non-atrioventricular model using Phoenix WinNonlin 8.1 software. RESULTS Compared with the control group， the AUC0－24 h， AUC0－∞ and cmax of ferulic acid in the HMG group were significantly increased （P＜0.05）； the AUC0－24 h， AUC0－∞ ， MRT0－∞ ， t1/2 and cmax of paeoniflorin increased， but there was no significant difference between 2 groups （P＞0.05）； the AUC0－24 h and MRT0-∞ of rosmarinic acid were significantly increased or prolonged （P＜0.05）. C ONCLUSIONS In HMG model rats， the exposure of ferulic acid， paeoniflorin and rosmarinic acid in Xiangshao sanjie oral liquid all increase， and the retention time of rosmarinic acid is significantly prolonged.

ObjectiveTo construct a large language model （LLM）-based intelligent pre-consultation system for traditional Chinese medicine （TCM） to improve efficacy of clinical practice. MethodsA TCM large language model was fine-tuned using DeepSpeed ZeRO-3 distributed training strategy based on YAYI 2-30B. A weighted undirected graph network was designed and an agent-based syndrome differentiation model was established based on relationship data extracted from TCM literature and clinical records. An agent collaboration framework was developed to integrate the TCM LLM with the syndrome differentiation model. Model performance was comprehensively evaluated by Loss function， BLEU-4， and ROUGE-L metrics， through which training convergence， text generation quality， and language understanding capability were assessed. Professional knowledge test sets were developed to evaluate system proficiency in TCM physician licensure content， TCM pharmacist licensure content， TCM symptom terminology recognition， and meridian identification. Clinical tests were conducted to compare the system with attending physicians in terms of diagnostic accuracy， consultation rounds， and consultation duration. ResultsAfter 100 000 iterations， the training loss value was gradually stabilized at about 0.7±0.08， indicating that the TCM-LLM has been trained and has good generalization ability. The TCM-LLM scored 0.38 in BLEU-4 and 0.62 in ROUGE-L， suggesting that its natural language processing ability meets the standard. We obtained 2715 symptom terms， 505 relationships between diseases and syndromes， 1011 relationships between diseases and main symptoms， and 1 303 600 relationships among different symptoms， and constructed the Agent of syndrome differentiation model. The accuracy rates in the simulated tests for TCM practitioners， licensed pharmacists of Chinese materia medica， recognition of TCM symptom terminology， and meridian recognition were 94.09%， 78.00%， 87.50%， and 68.80%， respectively. In clinical tests， the syndrome differentiation accuracy of the system reached 88.33%， with fewer consultation rounds and shorter consultation time compared to the attending physicians （P＜0.01）， suggesting that the system has a certain pre- consultation ability. ConclusionThe LLM-based intelligent TCM pre-diagnosis system could simulate diagnostic thinking of TCM physicians to a certain extent. After understanding the patients' natural language， it collects all the patient's symptom through guided questioning， thereby enhancing the diagnostic and treatment efficiency of physicians as well as the consultation experience of the patients.

Head and neck tumors are one of the major diseases that threaten human health. Targeted chemotherapy is an important treatment for head and neck tumors. However, many anti-cancer drugs are difficult to reach effective concentrations in tumors and can cause damage to normal tissues. Therefore, the efficient delivery of anti-tumor drugs, improvement of their therapeutic effects, and reduction of their adverse effects on the whole body and locally are urgent issues in targeted drug research. Liposomes have been widely studied due to their unique characteristics, including amphiphilicity, biocompatibility, biodegradability, and low toxicity. This article outlines the current applications and prospects of liposome drug delivery systems in different treatment modalities for head and neck tumors in recent years, aiming to provide more options for the treatment of head and neck tumors.

Objective To describe the incidence and mortality of brain tumors in China in 2020 and to predict the disease burden up to 2040.Methods The brain tumor incidence and mortality in 2020 were recorded based on the data from International Agency for Cancer Research(IARC),Cancer Today database.The incidence and mortality were standardized by age using Segi's world standard population.The burden of brain tumors in 2040 was predicted with assuming that national rates remained constant in 2020.Results It was estimated there were approximately 79 600 new brain tumors cases and 65 200 deaths in China in 2020.The age-standardized incidence and mortality rates of brain tumors in China were 4.1/100 000 and 3.2/100 000,respectively,which were lower than the United States of America,most of European countries and Australia.The incidence and mortality were higher than Africa,central America,and the Caribbean.From 2020 to 2040,the brain tumors cases and deaths are predicted to have an increase as 32.1%and 41.5%respectively.Conclusions The disease burden of brain tumors was still heavy in China.Further studies are urgently needed to clarify the epidemic trend of tissue typing and risk factors of brain tumors,which may support the development of effective prevention strategies.

Syndrome is an important concept in the theoretical system of tradtional Chinese medicine （TCM）， and the four-dimensional attributes of syndrome are proposed based on clinical practice， namely materiality， regularity， complexity and holism. The materiality of syndrome is an objective existence that can be perceived and seen， and it can be perceived from more levels by using modern science and technology to explore the visualisation， objectification and digitisation of syndrome； the regularity of syndrome is hierarchical， can be grasped， for example in the beginning of the epidemic the pathogen is unknown， and grasping the regularity of syndrome can make a rapid response in the treatment of the epidemic； the complexity of syndrome is not only reflected in the geographical， seasonal and individual differences， but also reflected in the development of the dynamics of a certain period of law， especially for the epidemic disease with characteristics of rapid onset， rapid change， so changeable syndrome， bad syndrome can appear at any time， and an objective and comprehensive grasp of the complexity of the syndrome can help improve the diagnosis and treatment of epidemic disease； the holism of syndrome not only embodied in the human body is a whole， the form of God as a whole， but also emphasised that man and nature are a whole， so more emphasis on man and nature as a whole. The occurrence of epidemics usually due to the unexpected qi appeared not the time， and the holism view of man and nature is an effective way to prevent and control epidemics. With the syndromes as the core， we explored the effective treatment strategy of epidemic disease combined with syndromes to provide ideas for the prevention and control of the epidemics.

Objective:To investigate the clinical effect of super-thin free anterolateral thigh (ALT) flap at the junction plane of superficial and deep fat of superficial fascia to repair the soft tissue defects of the foot.Methods:The clinical data of patients with foot soft tissue defects admitted to Northern Jiangsu People’s Hospital Affiliated to Yangzhou University from June 2017 to December 2022 were retrospectively analyzed. During the operation, the super-thin free ALT flap on the affected side was harvested at the junction of superficial and deep fat of superficial fascia to repair the foot wound. The donor site wound was sutured directly or repaired with full-thickness skin graft. The flap survival and complications were observed after the operation, and the operation effect was evaluated from the following five aspects. (1) The Maryland foot function score was used to evaluate the recovery of foot function. The full score was 100 points, of which 90-100 points were excellent, 75-89 points were good, 50-74 points were fair, and < 50 points were poor. (2) The Vancouver scar scale (VSS) was used to evaluate the scar condition of the foot. The total score was 0-15 points. The higher the score, the more serious the scar. (3) The cold intolerance symptom severity (CISS) scale was used to evaluate the cold tolerance of the affected foot. The total score was 4-100 points. The higher the score, the more serious the symptoms. (4) Measuring static two-point discrimination to evaluate foot sensation, the smaller the measured value, the better the sensory recovery. (5) The satisfaction of patients with foot appearance was investigated, which was divided into five grades: very satisfied, satisfied, general, dissatisfied and very dissatisfied. Descriptive analysis of the data was performed using SPSS 26.0 software.Results:A total of 13 patients with foot soft tissue defects were enrolled, including 8 males and 5 females. The mean age was 54.7 years (range, 39-70 years). There were 10 cases of left foot and 3 cases of right foot. The wound area after thorough debridement ranged from 5.5 cm ×5.0 cm to 22.0 cm ×18.0 cm. The operation time was (145.1 ± 30.6) min. The area of the flap was 6.0 cm×5.5 cm to 23.5 cm×19.0 cm, and the thickness was (5.2 ± 1.1) mm (range, 3.0- 6.5 mm). The wound at the donor site was sutured directly in 9 cases, and coverd with the abdominal full-thickness skin graft in 4 cases. After the operation, 1 patient had partial epidermal necrosis at the distal end of the flap, 1 patient had venous crisis.The flaps survived after symptomatic treatment. The remaining 11 flaps survived smoothly. The patients were followed up for 12 to 20 months, with an average of 16 months. The foot flaps were soft and free of damage, and no secondary fat reduction or plastic surgery was required. There were no complications such as wound dehiscence, skin graft necrosis, muscle hernia, and quadriceps weakness in 13 cases of donor site except for hypoesthesia caused by scar hyperplasia in 4 cases with skin graft. At the last follow-up, the Maryland foot function score was (87.4±7.3) points, of which 7 cases were excellent, 4 cases were good, and 2 cases were fair. The excellent and good rate was 11/13. The foot scar was not obvious, the VSS score was (3.2±1.2) points. The foot was more tolerant to cold and the sensory recovery was better, the CISS score was (37.5±7.1) points and the static two-point discrimination was (13.9±1.0) mm. One month after the operation, the results of patients’ satisfaction with foot appearance were as follows: 11 cases were very satisfied and 2 cases were satisfied.Conclusion:The super-thin free ALT flap is obtained at the junction plane of superficial and deep fat of superficial fascia to repair the soft tissue defect of the foot, which can optimize the operation time. The appearance and function of the foot recover well after the operation, avoiding the secondary shaping operation, reducing the damage to the donor site, and the patients are satisfied.

Aging and age-related ailments have emerged as critical challenges and great burdens within the global contemporary society.Addressing these concerns is an imperative task,with the aims of postponing the aging process and finding effective treatments for age-related degenerative diseases.Recent investigations have highlighted the significant roles of nicotinamide adenine dinucleotide(NAD+)in the realm of anti-aging.It has been empirically evidenced that supplementation with nicotinamide mononucleotide(NMN)can elevate NAD+levels in the body,thereby ameliorating certain age-related degenerative diseases.The principal anti-aging mechanisms of NMN essentially lie in its impact on cellular energy metabolism,inhibition of cell apoptosis,modulation of immune function,and preservation of genomic stability,which collectively contribute to the deferral of the aging process.This paper critically reviews and evaluates existing research on the anti-aging mechanisms of NMN,elucidates the inherent limitations of current research,and proposes novel avenues for anti-aging investigations.
