Polycystic ovary syndrome（PCOS） and its resulting infertility is one of the common diseases of gynecology and reproductive endocrinology. The phosphatidylinositol 3-kinase/protein kinase B（PI3K/Akt） signaling pathway is relatively well-studied in the development of intervention in PCOS， and the experiments on PCOS in rats conducted by traditional Chinese medicine through this signaling pathway is also the main direction of mechanistic research. In this paper， 20 articles published in academic journals in the past 5 years were selected through the corresponding criteria， and the objective situation and existing problems of the selected research projects were analyzed from five aspects， namely， baseline data， modeling and treatment， grouping， evaluative indexes， and pharmacodynamic indexes. It is found that there were different degrees of problems in each research project， such as the observation indicators of modeling， criteria for judging the success of the model， the treatment period， the calculation of dosage of prescription/active ingredients and specific dosage were not clearly defined， which could easily lead the bias of the results or reduce the validity of experimental data. Based on this， the list of PCOS rat experimental research operations was formed， involving five categories of experimental rats， model construction， study implementation， outcome measures and analysis and report with a total of 21 operation lists， with a view to provide a reference for the subsequent PCOS experiments related to scientific research and helping to form high-quality results.

ObjectiveTo analyse the clinical characteristics of different traditional Chinese medicine （TCM） syndromes in patients with heart failure based on information from electronic medical record. MethodsA cross-sectional study was conducted to collect clinical data of all inpatients with heart failure in the Department of Cardiology， Affiliated Hospital of Liaoning University of Traditional Chinese Medicine from January 1， 2019 to December 31， 2020. A database of clinical TCM data was established to explore the characteristics of clinical data of basic information， syndromes and syndrome element types， and biochemical indexes. The distribution of TCM syndromes and syndrome elements in heart failure patients were also analysed， and the basic information and biochemical indexes of the patients with top 7 different TCM syndrome types were compared. ResultsA total of 1676 inpatients with heart fai-lure were included. The top 7 TCM syndromes of heart failure were syndrome of phlegm turbidity and blood stasis （477 cases， 28.46%）， syndrome of qi deficiency and blood stasis （439 cases， 26.19%）， syndrome of qi deficiency and blood stasis with water retention （274 cases， 16.35%）， syndrome of yang deficiency with water retention （145 cases， 8.65%）， syndrome of qi and yin deficiency （104 cases， 6.21%）， syndrome of qi and yin deficiency with blood stasis （80 cases， 4.77%）， syndrome of heart yang deficiency （59 cases， 3.52%）. Among the 1676 patients， 6 syndrome elements accounted for more than 5%. Blood stasis accounted for the highest proportion of TCM syndrome element type （1292 cases， 77.09%）， followed by qi deficiency （919 cases， 54.83%）， phlegm （498 cases， 29.71%）， water retention （434 cases， 25.89%）， yang deficiency （215 cases， 12.82%） and yin deficiency （191 cases， 11.40%）. Among the 1676 patients， 1308 cases of acute heart failure mainly showed syndrome of phlegm turbidity and blood stasis （386 cases， 29.51%）， and 368 of chronic heart fai-lure mainly showed syndrome of qi deficiency and blood stasis （118 cases， 32.07%）. Patients with syndrome of phlegm turbidity and blood stasis had the shortest disease duration of 0.3 months， while those with syndrome of heart yang deficiency had the longest disease duration of 15 months. The proportion of syndrome of phlegm turbidity and blood stasis was the highest in patients with heart failure combined with coronary artery disease， the proportion of syndrome of qi deficiency and blood stasis with water retention was the highest in patients with heart failure combined with atrial fibrillation， and the proportion of patients with syndrome of qi deficiency and blood stasis with water retention and syndrome of yang deficiency with water retention in those applying diuretics during the hospital stay was the highest with more than 86%. The different 7 TCM syndromes showed statistically difference in patients with complications including coronary artery disease， old myocardial infarction， atrial fibrillation， pre and post-admission medication usage including intravenous vasodilators， cardiac stimulants， diuretics， and level of blood chloride， blood urea， blood creatinine， blood bicarbonate， blood albumin， and blood total bilirubin （P＜0.05）. ConclusionThe most common TCM syndromes in patients with heart failure are syndrome of phlegm turbidity and blood stasis and syndrome of qi deficiency and blood stasis. Different TCM syndromes have different characteristics in gender， disease complications， medication before and after admission， and blood indexes.

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.
