Objective To study the effect of practicing traditional Chinese medicine(TCM)guidance on the health in weightless conditions based on the examination results of the TCM diagnostic instrument.Methods 6 subjects in weightless conditions practiced TCM guidance for 14 consecutive days,once a day for 8 minutes each time.The Digital TCM Diagnostic Instrument and TCM Syndrome Diagnosis Scale were used to collect information before and after their practice of TCM guidance through diagnostic methods of observation,palpation and inquiry according to TCM theory.The data such as the degree of virtual-reality,pulse rate,and characteristic parameters of pulse diagrams h3/h1,h4/h1,t1,h1/t1 were processed and analyzed,and the changes before and after the practice were compared.Results Compared with before the practice,the degree of deficiency syndrome was significantly reduced after practicing TCM guidance(P<0.05),the pulse rate was significantly decreased(P<0.01),and the pulse diagnosis parameters h3/h1 and t1 were significantly decreased(P<0.05),while h4/h1 and h1/t1 showed no significant changes.Conclusion Practicing TCM guidance in weightless conditions is helpful for enhance cardiovascular regulatory function,correcting symptom bias,adjusting the body's balance state,and has a positive effect on health.

Glaucoma is the leading irreversible blinding eye disease worldwide,and intraocular pressure(IOP)plays a key role in the occurrence and development of glaucoma.However,the underlying IOP regulatory mechanism remains un-clear.Currently,clinical IOP-lowering drugs work either by reducing aqueous humor formation or increasing aqueous hu-mor outflow with limited reduction amplitude.Recent studies demonstrate that IOP may be regulated by autonomic nerves.To understand the distribution and regulatory mechanism of autonomic nerves in the aqueous humor outflow pathway and provide new ideas for IOP-lowering study and novel drug exploration,we review the roles of the autonomic nervous system in the formation and outflow of aqueous humor in this article.

In the field of dental aesthetics,digital aesthetic design plays a crucial role in helping dentists to predict treatment outcomes vis-ually,as well as in enhancing the consistency of knowledge and understanding of aesthetic goals between dentists and patients.It serves as the foundation for achieving ideal aesthetic effects.However,there is no clear standard for this digital process currently in China and abroad.Many dentists lack of systematic understanding of how to carry out digital aesthetic design for treatment.To establish standardized processes for dental aesthetic design and to improve the homogeneity of treatment outcomes,Chinese Society of Digital Dental Industry(CSD-DI)convened domestic experts in related field to compile this consensus.This article elaborates on the key aspects of digital aesthetic data collection,integration steps,and the digital aesthetic design process.It also formulates a decision tree for dental aesthetics at macro level and outlines corresponding workflows for various clinical scenarios,serving as a reference for clinicians.

ObjectiveTo explore the beneficial role and potential mechanism of intermittent fasting in olanzapine-induced metabolic disorders. MethodsC57BL/6J mice were randomly divided into four groups: Saline + ad libitum (Saline+Ad libitum), Saline + intermittent fasting (Saline +IF), olanzapine administration + ad libitum (Olanzapine+ Ad libitum), and olanzapine administration + intermittent fasting (Olanzapine+IF)， with eight mice in each group. The IF group adopted the 5∶2 scheme, that is, fasting on Monday and Thursday every week, and eating freely in the rest of the time. Ad libitum feeding as the control of intermittent fasting, Saline gavage as the control of olanzapine administration. The experiment lasted for 12 weeks. The differences of body mass, liver mass and epididymal adipose tissue mass were compared between the olanzapine-treated group and the control group after IF intervention. The body fat mass, lean body mass, and visceral fat infiltration of mice were analyzed by nuclear magnetic resonance and HE staining, respectively. Furthermore, the levels of fasting blood glucose, insulin, and insulin resistance index (HOMA-IR) in the process of glucose metabolism were also measured by glucose oxidase method and radioimmunoassay, respectively. The effects of IF on H₂O₂ release and the level of cytochrome C mRNA, a marker related to mitochondrial damage, were detected by ELISA and real-time fluorescence quantitative PCR. ResultsAfter 12 weeks of treatment, olanzapine induced a significant increase in body mass, body fat, lean body mass and visceral fat infiltration (P<0.05), as well as fasting blood glucose, insulin, and HOMA-IR (P<0.05); however, IF significantly reduced the above indicators (P<0.05). Further studies showed that the release of H₂O₂ and the expression of Cytochrome C mRNA in adipose tissue of mice after intermittent fasting treatment were significantly decreased (P<0.05). ConclusionIntermittent fasting therapy can alleviate olanzapine-induced metabolic disorders in mice. The underlying mechanism may involve the inhibition of oxidative stress level and the maintenance of mitochondrial functions.

Objective:To investigate the correlation of excessive platelet (Plt) recovery at the first time of achieving morphologic complete remission (CR) after induction chemotherapy with minimal residual disease (MRD) and the clinical features of acute myeloid leukemia (AML).Methods:The clinical data of newly-treated 57 AML patients (except for acute promyelocytic leukemia) who achieved CR after induction chemotherapy in Jinjiang People's Hospital from January 2016 to December 2021 were retrospectively analyzed. A total of 57 newly diagnosed adult AML patients were divided into excessive Plt recovery group (Plt recovery>350×10 9/L) and normal Plt recovery group [Plt recovery: (100-350)×10 9/L] according to the Plt recovery. Meanwhile, the MRD was analyzed by using multiparameter flow cytometry (MFC) in patients achieving CR after receiving 1 course of standard treatment regimen or 1-2 courses of demethylation drugs combined with pre-conditioning regimen. The clinical features and negative rate of MRD between the two groups were compared. Results:Among 57 CR patients, 31 (54.4%) patients had CR with excessive Plt recovery and MFC-MRD negative rate was 67.7% (21/31); 26 (45.6%) had CR with normal Plt recovery and MFC-MRD negative rate was 38.5% (10/26); and the difference in the proportion of MRD negative patients between the both groups was statistically significant ( χ2 = 4.89, P = 0.027). There were no statistically differences in the proportions of patients with different gender, age, WBC at initial diagnosis, Plt, chemotherapy regimen and risk degree classification between the two groups (all P > 0.05). Conclusions:In AML patients, excessive Plt recovery at the first time of achieving morphologic CR after induction chemotherapy is associated with negative MRD, which has a certain value in the judgement of therapeutic effect.

Purpose: There is no optimal prognostic model for T-cell lymphoblastic lymphoma (T-LBL). Here, we discussed the predictive value of total metabolic tumor volume (TMTV) and total lesion glycolysis (TLG) measured on 18F-fluorodeoxyglucose positron emission tomography–computed tomography (PET-CT) in T-LBL. Materials and Methods: Thirty-seven treatment naïve T-LBL patients with PET-CT scans were enrolled. TMTV was obtained using the 41% maximum standardized uptake value (SUVmax) threshold method, and TLG was measured as metabolic tumor volume multiplied by the mean SUV. Progression-free survival (PFS) and overall survival (OS) were analyzed by Kaplan-Meier curves and compared by the log-rank test. Results: The optimal cutoff values for SUVmax, TMTV, and TLG were 12.7, 302 cm3, and 890, respectively. A high SUVmax, TMTV, and TLG indicated a shorten PFS and OS. On multivariable analysis, TMTV ≥ 302 cm3, and central nervous system (CNS) involvement predicted inferior PFS, while high SUVmax, TLG and CNS involvement were associated with worse OS. Subsequently, we generated a risk model comprising high SUVmax, TMTV or TLG and CNS involvement, which stratified the population into three risk groups, which had significantly different median PFS of not reached, 14 months, and 7 months for low-risk group, mediate-risk group, and high-risk group, respectively (p < 0.001). Median OS were not reached, 27 months, and 13 months, respectively (p < 0.001). Conclusion Baseline SUVmax, TMTV, and TLG measured on PET-CT are strong predictors of worse outcome in T-LBL. A risk model integrating these three parameters with CNS involvement identifies patients at high risk of disease progression.

Objective To establish a rat model of glucocorticoid-induced osteoporosis(GIOP)and to explore the interventional effect of the Chinese medicine Fufang Zhenzhu Tiaozhi(FTZ)capsules on regulation of mitogen-activated protein kinase kinase kinase 2(MEKK2)-Wnt coupling and inhibiting β-catenin ubiquitination, and to investigate the effect of FTZ on the bone mineral density and cell osteogenic ability. Methods SPF male rats were randomly divided into normal control group,methylprednisolone group(model group),methylprednisolone + saline group(blank control group) and methylprednisolone + FTZ group(experimental group). The proximal femoral cancellous bone was examined by mi-cro-CT and histopathology,and assessment of expressions of Wnt3a,MEKK2,and β-catenin proteins. Bone mesenchymal stem cells(BMSCs were isolated and treated with serum containing FTZ,stained by alkaline phosphatase and alizarin red. The expressions of osteogenic differentiation-related genes ALP,Runx2 and OCN,the expressions of MEKK2 and β-catenin proteins,and the transcription level of β-catenin/TCF were determined. Results 1)The micro-CT imaging showed that compared with the control group, the BV/TV, Tb.Th and Tb/N expressions were significntly decreased, and Tb/sp in-creased in the experimental group(P<0.05). Region of interest(ROI)three-dimensional reconstruction of trabecular bone in the experimental group showed improvement of bone trabeculae and local bone repair. 2)The pathology using he-matoxylin and eosin staining showed that in the experimental group,the bone trabecular density was higher than that of the model group,and observed a better trabecula morphology. 3)The Wnt3a,MEKK2 and β-catenin expressions in the exper-imental group were significantly increased compared with the model model(P<0.05). 4)After treated with FTZ and BMP2,the result of alkaline phosphatase and alizarin red staining indicated an enhanced osteogenic response(P<0.05) in the GIOP rat models. 5)After treatment with seum containing FTZ,The BMSCs isolated from the GIOP rats enhanced the transcriptional activity of β-catenin/TCF/LEF(P<0.05)and promoted the expression of β-catenin and MEKK2 pro-teins(P<0.05). Conclusions FTZ can ameliorate GIOP by regulating the MEKK2-Wnt coupling and inhibiting the β-catenin ubiquitination,and improve the bone microstructure.
