Based on spleen deficiency-phlegm dampness as the core pathogenesis of obesity， and integrating recent advances in modern medicine regarding the key role of immune inflammation in obesity， this paper proposes a multidimensional pathogenic network of "obesity-spleen deficiency-phlegm dampness-immune imbalance". Various traditional Chinese medicine （TCM） herbs that strengthen the spleen， regulate qi， and resolve phlegm and dampness can treat obesity by improving spleen-stomach transport and transformation， promoting water-damp metabolism， and regulating immune homeostasis. This highlights immune inflammation as an important entry point to elucidate the TCM concepts of "spleen deficiency-phlegm dampness" and the therapeutic principle of "strengthening the spleen and eliminating dampness to treat obesity". By systematically analyzing the intrinsic connection between "spleen deficiency generating dampness， internal accumulation of phlegm dampness" and immune dysregulation in obesity， this paper aims to provide theoretical support for TCM treatment of obesity based on dampness.

ObjectiveTo construct a macro-evaluation tool for dampness syndrome （DS） animal model， which will provide a basis for experimental research on dampness syndrome in traditional Chinese medicine （TCM）. MethodsConceptual framework of this study was clarified through discussions within the core working group， and dimensions of the evaluation of the animal model of DS were identified according to TCM principles. We searched CNKI， Wanfang， VIP and SinoMed databases from the inception to June 30th， 2023， on experiments involving dampness syndrome animals to create a pool of items about DS animal models. The core items were selected and extracted for factor analysis and cluster analysis. An expert importance rating questionnaire was developed based on the results of the literature review， analyzing the distribution of item scores， importance averages， and coefficient of variation. Through a comprehensive analysis of literature， expert importance scoring， and specific expert opinions， items that did not meet anyone of the criteria of average importance rating ≥2.04， coefficient of variation ≤30%， or literature eva-luation frequency ≥2% were removed， thereafter， the macro-evaluation tool for DS animal model was preliminarily constructed. ResultsSpirit and body state， autonomic activity state， body surface characteristics， diet， urination and defecation， tongue manifestation， and motor behavior assessment were constructed as the seven dimensions in the evaluation of DS animal model. A total of 348 papers about animal experiments were included and analyzed， resulting in a saturated pool of 72 items， which was refined to 38 core items of DS animal models. Factor analysis obtained 16 common factors， which were further clustered into two categories， named dampness transforming from heat syndrome and dampness transforming from cold syndrome. The expert importance scoring showed that the Kendall harmony coefficient was 0.359 （P＜0.05） indicating a high level of agreement， coordination and reliability among the experts. Notably， 50% or more of the experts considered the items thick and greasy tongue coating， unclean perianal area， loose stools， lethargy， unformed stools， and listless expression as very important. The median scores for all items were 2.04（1.73， 2.37）， with a coefficient of variation ranging from 19.73% to 53.38%. After expert evaluation， the macro-evaluation tool for DS animal model in TCM with 33 items and corresponding criteria for assessing the formation of DS models was finally contructed. ConclusionThe Macro-evaluation tool for DS animal model in TCM is highly scientific， credible， and operable， and can be utilized in DS animal experiments after its characteristics are actually evaluated.

Aconitum kusnezoffii is a traditional Chinese medicine of Ranunculaceae family. Its toxicity is relatively strong, and its dosage is similar to that of poisoning. In clinical practice, poisoning events are often caused by excessive dosage or improper use. There is no specific antidote for kusnezoff root poisoning. Severe kusnezoff root poisoning can cause malignant arrhythmia and even death.A case of severe kusnezoff monkshood poisoning was reported in January 2021, which was treated with nificaran hydrochloride for injection in the emergency medicine department of the First Hospital of Handan City. The patient developed ventricular tachycardia, ventricular fibrillation and AS syndrome. In addition to conventional treatment, the patient did not have arrhythmia again after intravenous injection of 25 mg of nifekalan load and continuous pumping of 0.4 mg/kg/h for 7 hours, and did not relapse after discontinuation of nifekalan 24 hours later. It is suggested that the malignant arrhythmia caused by clinical severe kusnezoff monkshood poisoning can be controlled by nifekalan. Whether nifekalan is superior to conventional antiarrhythmic drugs still needs more accumulation and verification of clinical application data.

The constitutive androstane receptor (CAR, NR3I1) belongs to nuclear receptor superfamily. It was reported that CAR agonist TCPOBOP induces hepatomegaly but the underlying mechanism remains largely unknown. Yes-associated protein (YAP) is a potent regulator of organ size. The aim of this study is to explore the role of YAP in CAR activation-induced hepatomegaly and liver regeneration. TCPOBOP-induced CAR activation on hepatomegaly and liver regeneration was evaluated in wild-type (WT) mice, liver-specific YAP-deficient mice, and partial hepatectomy (PHx) mice. The results demonstrate that TCPOBOP can increase the liver-to-body weight ratio in wild-type mice and PHx mice. Hepatocytes enlargement around central vein (CV) area was observed, meanwhile hepatocytes proliferation was promoted as evidenced by the increased number of KI67

Objective:To investigate the neuroimaging relationship between tau protein deposition and brain atrophy, and assess their relationships with cognitive decline in Alzheimer′s disease (AD) patients.Methods:From April 2017 to October 2019, 26 AD patients (12 males, 14 females, age (70.7±12.2) years) and 19 cognitively normal controls (CN; 9 males, 10 females, age (65.6±8.1) years) in Chinese PLA General Hospital were retrospectively enrolled. All subjects received (S)-6-[(3- 18F-fluoro-2-hydroxy)propoxy]-2-(4-methylaminophenyl)quinoline ( 18F-THK5317) PET/MR and the standardized uptake value ratio (SUVR) and gray matter volume (GMV) were measured. General linear model (GLM) was used to evaluate the differences of SUVR and GMV between two groups. Pearson correlation analysis was used to assess the relationships between SUVR and GMV, and relationships of SUVR and GMV with Mini-Mental State Examination (MMSE) scores in AD patients. Results:Compared with CN, the AD patients showed significantly increased 18F-THK5317 retention in lateral temporal, frontal, posterior cingulated/precuneus and occipital cortex with significant differences of SUVR between two groups (2.18±0.54 vs 1.78±0.09, 2.13±0.50 vs 1.82±0.06, 2.03±0.45 vs 1.69±0.08, 2.18±0.57 vs 1.76±0.10, t values: 2.58-6.57, all P<0.001). The AD patients also showed decreased GMV in medial temporal, posterior cingulated/precuneus and orbitofrontal cortex ( t values: 3.67-8.85, all P<0.001). In AD patients, SUVR was negatively associated with GMV in bilateral lateral temporal cortex, pre-frontal cortex and orbital frontal cortex ( r values: from -0.52 to -0.43, all P<0.05). Both SUVR ( r=-0.599, P=0.001) and GMV ( r=0.443, P=0.023) were significantly correlated with MMSE scores in AD patients. Conclusion:AD patients have neocortical 18F-THK5317 abnormal uptake and GMV reduction, which are significantly correlated with cognitive decline.

Objective To evaluate the diagnostic efficiency of the parameters obtained from PET/MR in brain tumors.Methods In this prospective study,28 patients (21 males,7 females,age range: 6-82 years) with clinical suspicion of brain tumor from November 2012 to September 2015 underwent PET/MR multi-modality imaging.The examination of PET/MR included 11C-MET PET and multiple MR sequences.The qualities of images were estimated firstly.The ROC curve and the accuracy of SUVmax,ADCmean,rCBF and NAA/(Cho+Cre) ratio were calculated.The pathology or final clinical diagnosis was taken as the standard.The diagnostic efficiency of the multi-modality imaging was determined based on the cutoff values of the four parameters.Two-sample t test was used to analyze the differences of parameters between glioma group and inflammatory group.Results SUVmax,ADCmean,rCBF and NAA/(Cho+Cre) ratio were validated to be effective parameters in diagnosing brain tumors with the diagnostic accuracy of 89.3％(25/28),82.1％(23/28),78.6％(22/28) and 75.0％(21/28),respectively.The SUVmax exhibited the highest diagnostic accuracy,while the diagnostic efficiency of the combination of four parameters was superior to the separate parameter.The values of SUVmax,rCBF and NAA/(Cho+Cre) ratio were significantly different between glioma group(n=10) and inflammatory group(n=11;t values:-2.31,-3.11,-2.77,all P<0.05).Conclusions PET/MR can provide a one-stop examination with multi-modality imaging of brain.The obtained parameters SUVmax,ADCmean,rCBF and NAA/(Cho+Cre) ratio,especially their combination,have effective diagnostic values on brain tumor.

Objective To discuss the diagnostic value of serum sialic acid for glioma.Methods A retrospective study was conducted.The levels of sialic acid in serum samples of 95 glioma patients, 175 patients with brain benign tumor and 400 normal persons from October 2014 to March 2015 were detected by automatic biochemistry analyzer using enzymic method.The SNK-q test and analysis of variance were used to compare the difference of the groups.By making receiver operating characteristic ( ROC) curve, the cut-off value, sensitivity, specificity, positive predictive value and negative predictive value were calculated to assess the diagnostic value of serum salivary acid.Then the cut-off value was validated by using the serums of 30 glioma patients and 30 normal persons who were out-patients and healthy controls.Results The levels of serum sialic acid in patients with gliomas, patients with brain benign tumor and healthy individuals were (0.66 ±0.14 ) g/L, (0.61 ±0.09 )g/L, (0.54 ±0.07 )g/L.The serum salivary acid of glioma patients were higher than brain benign tumor patients (q=6.74,P<0.05) and normal persons (q=16.42,P<0.05), and there was no significant difference (F=1.67,P>0.05) among the glioma patients of different grades (8 of gradeⅠ,32 of gradeⅡ,24 of grade Ⅲ,31 of grade Ⅳ).There was no significant difference between the low grade patients (gradeⅠandⅡ) and the high grade patients (gradeⅢandⅣ) (t=0.55, P>0.05), but the level of serum sialic acid of high grade group had an increasing trend than the low grade group.The area under the ROC curves was 0.79.The cut-off value of serum salivary acid for diagnosing glioma was 0.61 g/L.The sensitivity was 67.74%, and the specificity was 80.60%.The positive predictive value was 44.68%, and the negative predictive value was 90.76%.Then the cut-off value was used as a diagnostic criteria, and the detected results of 30 glioma patients and 30 normal persons showed that the sensitivity was 63.30% and the specificity was 83.30%.Conclusions The serum sialic acid has good specificity and negative predictive value for diagnosing glioma.It may be a valuable diagnostic marker.

Objective To observe the clinical value of indocyanine green retention rate at 15 minutes (ICGR15) in the evaluation of hepatic functional reserve. Methods A total of 185 patients with liver disease, including 45 cases of liver failure, 90 cases of cirrhosis (child A, B and C, respectively), 20 cases of acute hepatitis, 30 cases of chronic hepatitis (mild, moderate). Expression levels of ICGR15 were compared between groups. Values of ICGR15, total bilirubin (TBIL), albumin (ALB), blood coagulation time (PT) were compared before treatment and one month after treatment in hepatic failure group. Levels of alanine aminotransferase (ALT), aspertate aminotransferase (AST), TBIL and ICGR15 were compared before treatment and 1 month after treatment in acute hepatitis group. Results Levels of ICGR15 (%) were 56.3±14.7, 28.9±9.6, 22.4±6.8 and 13.7±2.3 in liver failure group, liver cirrhosis group, acute hepatitis group and chronic hepatitis group, which showed a gradual downward trend (F=125.317, P<0.05). Among them, the levels of ICGR15 (%) were 17.3±5.4, 25.7±7.5 and 34.5±7.3 in Child A, B and C groups of liver cirrhosis group, which showed a gradual upward trend (P<0.05). After one month treatment, levels of TBIL, PT and ICGR15 were significantly lower than T helper 17 cells; intima-media thickness before the treatment in liver failure group. The levels of ALT, AST, TBIL and ICGR15 were significantly lower after treatment than those before treatment in acute hepatitis group (P<0.05). Conclusion ICGR15 can reflect hepatic reserved function, which is not affected by the application of albumin and fresh plasma, and makes up the deficiency of PT and ALB detection.
