Parkinson's disease （PD） is a complex neurodegenerative disease involving multiple systems and neurotransmitters. Due to the high clinical heterogeneity of PD，it is urgent to establish a comprehensive and long-term traditional Chinese medicine （TCM） management model. In this paper，the conceptual framework of full-cycle management of PD is preliminarily constructed：based on the evolution of the pathophysiological mechanisms of protein deposition and neurotransmitter disorder in PD，the three-stage syndrome characteristics of the prodromal stage （predominant healthy Qi with subtle pathogenic factors），the early clinical stage （declining healthy Qi with growing pathogenic factors） and the middle and late stages （overwhelming pathogenic factors with deficient healthy Qi） are longitudinally described. Through the syndrome differentiation of visceral manifestations，the etiology and pathogenesis of PD motor and non-motor symptoms were comprehensively analyzed，while the matching treatment methods and prescriptions were inferred，and the modular scheme of the combining main symptoms，accompanying symptoms and secondary symptoms was proposed. The conceptual gap of TCM regarding motor complications （'variable syndrome'） and PD-related hyperpyrexia syndrome （'critical syndrome'） was explained. This framework reflects the characteristics of combination of disease and syndrome and overall constant motion，and provides new theories and research ideas for individualized and whole-process management of PD in TCM.

BACKGROUND:Currently,treatment method for knee osteoarthritis includes oral medicine,joint cavity drug injection,and physiotherapy,but the curative effect is limited.Existing studies have confirmed that silicon-based bioceramics can promote cartilage and subchondral bone repair and vascular regeneration.OBJECTIVE:To explore the effect of different concentrations of silicon-based bioceramics injected into the knee joint cavity in the treatment of knee osteoarthritis in rats.METHODS:Silicon-based bioceramics-calcium silicate was prepared.Twenty-five SD rats were randomly divided into five groups,with five rats in each group.The healthy group did not receive any intervention,and the modeling group,low-dose calcium silicate group,high-dose calcium silicate group,and saline group used anterior cruciate ligament transection to establish bilateral knee osteoarthritis models.Four weeks after modeling,0.05 mL of 50 and 100 mg/mL calcium silicate solution were injected into the knee joint cavity in the low-dose calcium silicate group and high-dose calcium silicate group,respectively,and 0.05 mL of saline was injected into the knee joint cavity in the saline group,once a week for 4 consecutive weeks.In the fifth week of administration,bilateral knee joint Micro-CT detection,knee joint cartilage hematoxylin-eosin staining,and modified Mankin score were performed.RESULTS AND CONCLUSION:(1)Micro-CT quantitative analysis showed that compared with the healthy group,the volume fraction and number of trabeculae of the medial tibial plateau in the modeling group decreased(P＜0.05),and the separation of trabeculae increased(P＜0.05).Compared with the modeling group,the volume fraction and number of trabeculae of the medial tibial plateau in the low-dose calcium silicate group and the saline group increased(P＜0.05),and the separation of trabeculae decreased(P＜0.05).(2)Hematoxylin-eosin staining showed that the cartilage surface of the healthy group and the low-dose calcium silicate group was relatively smooth and flat,the chondrocytes were evenly distributed,without clustered chondrocytes,the tide line was complete,and the staining was uniform;the cartilage surface of the high-dose calcium silicate group was slightly uneven,the middle and deep cells were disordered,with a small number of clustered chondrocytes,the tide line was discontinuous,and the staining was uneven;the cartilage surface of the saline group and the modeling group was obviously rough,the cells were disordered,with a large number of clustered chondrocytes,the tide line disappeared,and the staining was uneven.The modified Mankin score of the healthy group was lower than that of the high-dose calcium silicate group,the saline group,and the modeling group(P＜0.05).The modified Mankin score of the high-dose calcium silicate group and the low-dose calcium silicate group was lower than that of the saline group and the modeling group(P＜0.05).(3)The results show that calcium silicate knee joint injection has a certain effect in the treatment of knee osteoarthritis.Compared with 100 mg/mL calcium silicate solution,50 mg/mL calcium silicate solution can promote the recovery of subchondral bone and cartilage.

Health economics evidence plays an important role in linking clinical value evidence with health resource allocation decisions in the development of clinical practice guidelines. It can not only effectively balance clinical effectiveness and economic feasibility but also avoid forming "idealized" recommendations that are detached from the affordability of the healthcare system or the burden-bearing capacity of patients. To promote guideline developers to use health economics evidence more standardizedly and fully, this paper conducts an in-depth analysis of the current application status, existing challenges, access channels, and application processes of health economics evidence in current guidelines, and on this basis, puts forward considerations and suggestions for strengthening and standardizing the application of health economics evidence in China's clinical practice guidelines.

OBJECTIVE To explore the mechanism of Yiqi yangyin huazhuo tongluo formula in ameliorating diabetic kidney disease （DKD） based on the gut microbiota-lipopolysaccharide （LPS）/Caspase-11/gasdermin D （GSDMD） pathway.METHODS A DKD mouse model was established by high-fat and high-sugar diet combined with intraperitoneal injection of low-dose streptozotocin. The successfully modeled mice were randomly divided into model group， metformin group （positive control， 200 mg/kg） and Yiqi yangyin huazhuo tongluo formula group （32.4 g/kg， calculated as crude drug dosage）， with 10 mice in each group； another 10 mice were set as the control group. Mice were intragastrically administered with corresponding drug solutions or normal saline once a day for 8 consecutive weeks. After the last administration， serum glycolipid metabolism indicators and urinary renal function indicators of mice were determined； the pathological and morphological changes of renal and colonic tissues were observed； LPS contents in renal tissues， colonic contents and serum were detected. 16S rRNA high-throughput sequencing was performed for gut microbiota analysis of colonic contents. The protein expressions of Occludin and zonula occludens-1 （ZO-1） in colonic tissues as well as Caspase-11 and GSDMD in renal tissues were detected.RESULTS Compared with the control group， the model group exhibited significantly elevated levels of serum fasting blood glucose， triglyceride， total cholesterol， serum creatinine， blood urea nitrogen and microalbumin， LPS contents in each sample， as well as protein expressions of Caspase-11 and GSDMD in renal tissues （ P ＜0.05）. The protein expressions of ZO-1 and Occludin in colonic tissues， together with Chao1 and Ace indices of gut microbiota， were markedly decreased （ P ＜0.05）， and the ratio of Firmicutes to Bacteroidetes was abnormally increased. Obvious histopathological changes were observed in renal and colonic tissues； the percentage of PAS-positive area in kidney was markedly increased （ P ＜0.05）. Compared with the model group， the Yiqi yangyin huazhuo tongluo formula group showed remarkable reductions in glycolipid metabolism and renal function-related indicators（except total cholesterol）， LPS contents in various samples， and renal protein expressions of Caspase-11 and GSDMD （ P ＜0.05）. The protein expression level of ZO-1 in colonic tissues and the Ace index of gut microbiota were significantly increased （ P ＜0.05）， and the relative abundance of beneficial genera including Bifidobacterium ， Faecalibaculum and Akkermansia in the gut microbiota was elevated.CONCLUSIONS The mechanism by which Yiqi yangyin huazhuo tongluo formula ameliorates DKD may be related to reshaping gut microbiota， repairing intestinal mucosal barrier， reducing LPS translocation into blood， and further inhibiting Caspase-11/GSDMD-mediated pyroptosis in kidney.

Objective:To design an inspection system for quality of metabolism tester based on alcohol combustion mode for human body,so as to realize assessment for accuracy degree of human metabolism tester.Methods:According to the specific indicators that were measured by the metabolism tester for human body,a simulation of bidirectional controllable flow and a simulation of component concentration of exhaled breath were designed and realized.Then,the ratio of alcohol consumption to oxygen consumption and carbon dioxide production were calculated by the formula of alcohol combustion.Finally,the metabolic indexes(volume of gas flow,oxygen consumption,dioxide carbon production,rate of energy metabolism,respiratory quotient)that were outputted by the inspection system for quality were calculated according to Weir formula.Furthermore,the verification for precision of simulation modules of exhale and inhalation,and weighing device module was carried out,and an application test of inspection system for quality was also carried out.Results:The errors of the volume of gas flow and alcohol consumption that were outputted by simulation modules of exhale and inhalation,and weighing device module were all within±1%,and the errors between the reference value of the metabolic index of the inspection system for quality and the actually measured value of the metabolic index of the hood calorimeter were all within 10%.Conclusion:There was higher consistency between inspection system for quality of metabolism tester for human body and the actual measurement data of calorimeter,which can better simulate the process of respiratory metabolism of human body,and provide standardized testing means for the performance verification of metabolic tester.

Objective:To explore the pathogenesis,clinical features,treatment strategies,and prognosis of pediatric lymphoepithelioma-like carcinoma(LELC).Methods:A retrospective analysis was conducted on the clinical data of patients with LELC aged<18 years,treated at Sun Yat-sen University Cancer Center from March 2008 to June 2023.Results:A total of 19 children and adolescents were included in the analys-is,comprising 10 males(52.6%)and 9 females(47.4%),with a median age of 12.9(4.3-17.0)years.Fourteen patients(73.7%)lived in Guangdong province,with the remainder scattered across other regions.Primary LELC sites were the mediastinum(11 cases,57.9%),parot-id glands(4 cases,21%),neck(1 case,5.3%),lungs(1 case,5.3%),salivary glands(1 case,5.3%),and submandibular glands(1 case,5.3%).Among these,15 patients(78.9%)had at least one distant metastasis at initial diagnosis,with common metastasis sites being cervical lymph nodes.Multivariate Cox regression analysis identified tumor volume≥801 cm3 as an independent adverse prognostic factor of poor overall survival(OS)(P<0.01).The 2-year OS and progression-free survival(PFS)rates were 84.2%and 57.9%,respectively.The 2-year OS for pa-tients who underwent surgery,chemotherapy,and radiotherapy was 100%,compared with 25%for those who received only partial treat-ment(P=0.007).The 2-year PFS rate was significantly higher in patients receiving first-line combination therapy with programmed death-1(PD-1)antibodies(100%)compared with those not treated with PD-1 antibodies(38.5%)(P=0.020).For patients with tumor volume≥801 cm3,the 2-year OS was 40.0%,whereas for those with a tumor volume<801 cm3,the 2-year OS was 100%(P<0.001).The 2-year OS for pa-tients who underwent radiotherapy was 100%,while it was 0 for those who did not receive radiotherapy(P<0.001).Conclusions:Pediatric LELC exhibits a relatively favorable prognosis with multidisciplinary treatment,including surgery,chemotherapy,and radiotherapy.The com-bined use of PD-1 antibodies at the time of initial diagnosis could offer potential benefits and warrants further exploration.
