Processing for deodorization is widely used in the production of animal-derived Chinese medicinal materials. In this study, Heracles Neo ultra-fast gas-phase electronic nose combined with chemometrics was employed to analyze the overall odor difference of Cervi Cornu Pantotrichum(focusing on that derived from Cervus nippon Temminck in this study) before and after processing. The results showed that the electronic nose effectively distinguished between the medicinal materials and decoction pieces of Cervi Cornu Pantotrichum. HS-GC-MS was used to identify and quantify the volatile components in the medicinal materials and decoction pieces of Cervi Cornu Pantotrichum, and 35 and 37 volatile components were detected in the medicinal materials and decoction pieces, respectively. The medicinal materials and decoction pieces contained 28 common volatile components contributing to the odor of Cervi Cornu Pantotrichum. The odor activity value(OAV) of each volatile component was calculated based on the olfactory threshold and relative content. The results showed that there were 17 key odor substances such as isovaleraldehyde, 2-methylbutanal, isobutyraldehyde, hexanal, and methanethiol in the medicinal materials and decoction pieces of Cervi Cornu Pantotrichum. All of them had bad odor and were the main source of the odor of Cervi Cornu Pantotrichum. The results of principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA) showed that there were significant differences in volatile components between the medicinal materials and decoction pieces of Cervi Cornu Pantotrichum. Based on the thresholds of P<0.05 and Variable Importance in Projection(VIP)>1, 21 differential volatile odor components were screened out. Among them, isopentanol, isovaleraldehyde, 2-methylbutanal, n-nonanal, and dimethylamine were the key differential odor compounds between the medicinal materials and decoction pieces of Cervi Cornu Pantotrichum. The odor compounds and their relative content reduced, and some flavor substances such as esters were produced after processing with wine, which was the main reason for the reduction of the odor after processing of Cervi Cornu Pantotrichum.

The combination of Aidi Injection(ADI) and doxorubicin(DOX) is a common strategy in the treatment of cancer, which can achieve synergistic anti-tumor effects while attenuating the cardiotoxicity caused by DOX. This study aims to investigate the mechanism of ADI in attenuating DOX-induced cardiotoxicity by multi-omics. DOX was used to induce cardiotoxicity in mice, and the cardioprotective effects of ADI were evaluated based on biochemical indicators and pathological changes. Based on the results, transcriptomics, proteomics, and metabolomics were employed to analyze the changes of endogenous substances in different physiological states. Furthermore, data from multiple omics were integrated to screen key regulatory pathways by which ADI attenuated DOX-induced cardiotoxicity, and important target proteins were selected for measurement by ELISA kits and immunohistochemical analysis. The results showed that ADI significantly reduced the levels of cardiac troponin T(cTnT) and N-terminal pro-B-type natriuretic peptide(NT-proBNP) and effectively ameliorated myocardial fibrosis and intracellular vacuolization, indicating that ADI showed therapeutic effect on DOX-induced cardiotoxicity. The transcriptomics analysis screened out a total of 400 differentially expressed genes(DEGs), which were mainly enriched in inflammatory response, oxidative stress, and myocardial fibrosis. After proteomics analysis, 70 differentially expressed proteins were selected, which were mainly enriched in the inflammatory response, cardiac function, and energy metabolism. A total of 51 differentially expressed metabolites were screened by the metabolomics analysis, and they were mainly enriched in multiple signaling pathways, including the inflammatory response, lipid metabolism, and energy metabolism. The integrated data of multiple omics showed that linoleic acid metabolism, arachidonic acid metabolism, and glycerophosphate metabolism pathways played an important role in DOX-induced cardiotoxicity, and ADI may exert therapeutic effects by modulating these pathways. Target validation experiments suggested that ADI significantly regulated abnormal protein levels of cyclooxygenase-1(COX-1), cyclooxygenase-2(COX-2), prostaglandin H2(PGH2), and prostaglandin D2(PGD2) in the model group. In conclusion, ADI may attenuate DOX-induced cardiotoxicity by regulating linoleic acid metabolism, arachidonic acid metabolism, and glycerophosphate metabolism, thus alleviating inflammation of the body.

OBJECTIVE: To analyze the factors influencing the development of refeeding syndrome (RFS) in patients with sepsis and its impact on clinical prognosis. METHODS: A retrospective case-control study method was used to collect the clinical data of patients with sepsis admitted to the intensive care unit (ICU) of Qingdao Municipal Hospital from December 2018 to December 2023. The patients were divided into RFS and non-RFS groups according to whether RFS occurred, and the basic data, nutritional status and assessment scale, laboratory indicators, nutritional intake, medical history and prognosis were compared between the two groups. Binary multifactorial Logistic regression analysis was used to screen the influencing factors of the occurrence of RFS in patients with sepsis. RESULTS: A total of 544 patients with sepsis were finally enrolled, of whom 250 did not develop RFS and 294 developed RFS, with an incidence of 54.0%. Compared with the non-RFS group, the patients in the RFS group had lower body mass index (BMI), albumin, prealbumin, baseline electrolytes (serum phosphorus, serum potassium, and serum magnesium), creatinine-height index, and protein intake, and had higher nutritional risk screening 2002 (NRS2002) score, sequential organ failure assessment (SOFA) score, calorie intake, and the proportions of feedings during the 48 hours of ICU admission, history of diabetes and septic shock. Binary multifactorial Logistic regression analysis showed that BMI [odds ratio (OR) = 0.910, 95% confidence interval (95%CI) was 0.857-0.947, P < 0.001], SOFA score (OR = 1.166, 95%CI was 1.085-1.254, P < 0.001), albumin (OR = 0.946, 95%CI was 0.902-0.991, P = 0.019), baseline serum phosphorus (OR = 0.343, 95%CI was 0.171-0.689, P = 0.003), baseline serum potassium (OR = 0.531, 95%CI was 0.377-0.746, P < 0.001), creatinine-height index (OR = 0.891, 95%CI was 0.819-0.970, P = 0.008), caloric intake (OR = 1.108, 95%CI was 1.043-1.178, P = 0.001), protein intake (OR = 0.107, 95%CI was 0.044-0.260, P < 0.001), and feedings during the 48 hours of ICU admission (OR = 0.592, 95%CI was 0.359-0.977, P = 0.040) and septic shock (OR = 0.538, 95%CI was 0.300-0.963, P = 0.037) were independent influence factors on the occurrence of RFS in septic patients. Of the 544 patients, 267 died at 28 days, with a mortality of 49.1%. The 28-day mortality of patients in the RFS group was significantly higher than that in the non-RFS group [54.4% (160/294) vs. 42.8% (107/250); χ² = 7.302, P = 0.007]. 544 patients had a length of ICU stay of 20 (17, 24) days. The patients in the RFS group had a significantly longer length of ICU stay than that in the non-RFS group [days: 20 (17, 25) vs. 19 (17, 23); Z = -2.312, P = 0.021]. CONCLUSIONS The incidence of RFS in septic patients is high. Factors influencing the occurrence of RFS in septic patients include BMI, SOFA score, albumin, baseline serum phosphorus, baseline serum potassium, caloric intake, protein intake, feeding within 48 hours of ICU admission, and septic shock. RFS prolongs the length of ICU stay and increases the 28-day mortality in patients with sepsis.

OBJECTIVE: To investigate the associations between eight serum per- and polyfluoroalkyl substances (PFASs) and regional fat depots, we analyzed the data from the National Health and Nutrition Examination Survey (NHANES) 2011-2018 cycles. METHODS: Multiple linear regression models were developed to explore the associations between serum PFAS concentrations and six fat compositions along with a fat distribution score created by summing the concentrations of the six fat compositions. The associations between structurally grouped PFASs and fat distribution were assessed, and a prediction model was developed to estimate the ability of PFAS exposure to predict obesity risk. RESULTS: Among females aged 39-59 years, trunk fat mass was positively associated with perfluorooctane sulfonate (PFOS). Higher concentrations of PFOS, perfluorohexane sulfonate (PFHxS), perfluorodecanoate (PFDeA), perfluorononanoate (PFNA), and n-perfluorooctanoate (n-PFOA) were linked to greater visceral adipose tissue in this group. In men, exposure to total perfluoroalkane sulfonates (PFSAs) and long-chain PFSAs was associated with reductions in abdominal fat, while higher abdominal fat in women aged 39-59 years was associated with short-chain PFSAs. The prediction model demonstrated high accuracy, with an area under the curve (AUC) of 0.9925 for predicting obesity risk. CONCLUSION PFAS exposure is associated with regional fat distribution, with varying effects based on age, sex, and PFAS structure. The findings highlight the potential role of PFAS exposure in influencing fat depots and obesity risk, with significant implications for public health. The prediction model provides a highly accurate tool for assessing obesity risk related to PFAS exposure.

OBJECTIVE: This study aimed to explore the association between body mass index (BMI) and mortality based on the 10-year population-based multicenter prospective study. METHODS: A general population-based multicenter prospective study was conducted at four sites in rural China between 2013 and 2023. Multivariate Cox proportional hazards models and restricted cubic spline analyses were used to assess the association between BMI and mortality. Stratified analyses were performed based on the individual characteristics of the participants. RESULTS: Overall, 19,107 participants with a sum of 163,095 person-years were included and 1,910 participants died. The underweight (< 18.5 kg/m ²) presented an increase in all-cause mortality (adjusted hazards ratio [ aHR] = 2.00, 95% confidence interval [ CI]: 1.66-2.41), while overweight (≥ 24.0 to < 28.0 kg/m ²) and obesity (≥ 28.0 kg/m ²) presented a decrease with an aHR of 0.61 (95% CI: 0.52-0.73) and 0.51 (95% CI: 0.37-0.70), respectively. Overweight ( aHR = 0.76, 95% CI: 0.67-0.86) and mild obesity ( aHR = 0.72, 95% CI: 0.59-0.87) had a positive impact on mortality in people older than 60 years. All-cause mortality decreased rapidly until reaching a BMI of 25.7 kg/m ² ( aHR = 0.95, 95% CI: 0.92-0.98) and increased slightly above that value, indicating a U-shaped association. The beneficial impact of being overweight on mortality was robust in most subgroups and sensitivity analyses. CONCLUSION This study provides additional evidence that overweight and mild obesity may be inversely related to the risk of death in individuals older than 60 years. Therefore, it is essential to consider age differences when formulating health and weight management strategies.

Objective To investigate the expression of T cell immunoglobulin and mucin domain-containing protein 3(TIM-3)in peripheral blood mononuclear cells and its relationship with non-small cell lung cancer(NSCLC).Methods TIM-3 expression in monocytes from the peripheral blood of 116 NSCLC patients and 37 healthy volunteers was analyzed via flow cytometry.The expression of TIM-3 in macrophages from tissues was detected via multiplex immunohistochemical staining.Transwell migration experiments were used to detect the migration ability of monocytes.Real-time PCR and ELISA were used to detect the mRNA and protein expression of TIM-3 in monocytes.Results Compared with that in healthy volunteers,TIM-3 expression was upregulated in the peripheral blood monocytes of NSCLC patients(P＜0.05).TIM-3 was expressed mainly in macrophages in adjacent tissues and positively correlated with its expression in monocytes in NSCLC patients(P＜0.05).Furthermore,high TIM-3 expression promoted monocyte migration in NSCLC patients(P＜0.05),and high TIM-3 expression in peripheral blood monocytes indicated poor prognosis(P＜0.05).Conclusion TIM-3 expression in peripheral blood monocytes may be a useful indicator of the disease prognosis of NSCLC patients and TIM-3 could be a new target for immunotherapeutic strategies.

Objective:To explore the application value of right-opening single flap valvuloplasty based on tubular stomach in gastrointestinal reconstruction after laparoscopic proximal gastrectomy.Method:Use a linear cutting stapler to make a parallel curve from the angle of the stomach to the junction of the gastric fundus to remove the lesser curvature of the stomach, and detach the gastric body about 5 cm away from the tumor to create a tubular stomach. Use a marker pen to draw a C-shaped seromuscular flap area with a width of 2.5 cm and a height of 3.5 cm 1.5 cm below the residual stomach closure nail, and create a free muscle flap in the gap between the plasma muscle layer and the submucosal layer. Make a transverse incision of 3 cm at the lower edge of the mucosal bed, and intermittently suture the entire lower edge of the gastric wall with 3 stitches. Under laparoscopy, use 4-0 barbed wire to suture the 1 cm wide muscular layer at the top of the tubular stomach and the posterior wall of the esophagus about 5 cm away from the esophageal stump with 3 stitches. Push the upper end of the tubular stomach into the mediastinum, and then tighten the barbed wire to ensure a tight fit between the stomach and the posterior wall of the esophagus. Use an ultrasonic scalpel to remove the esophageal stump, suture the entire posterior wall of the esophagus with the gastric mucosa, and use barbed wire to suture the anterior wall from left to right. The anastomotic site is completely covered with a free muscle flap, and the barbed line is used to continuously suture the muscle flap along the C-shaped line to the gastric pulp muscle layer at the edge of the mucosal bed, embedding the anastomotic site and completing the reconstruction of the digestive tract.Results:Clinical data of 23 patients (18 from the First Affiliated Hospital of Wenzhou Medical University and 5 from the Quzhou Hospital affiliated with Wenzhou Medical University) who underwent laparoscopic proximal gastrectomy, tubular gastroesophageal anastomosis, and pure manual right flap reconstruction surgery for esophagogastric junction adenocarcinoma and proximal gastric cancer from October 2023 to August 2024. There were 15 males and 8 females, with an age of (65.3±7.7) years, the BMI was (22.9±2.8) kg/m 2. All patients in the group successfully completed the surgery, with a surgery time of (218.5±38.1) minutes, including (73.5±19.2) minutes for anastomosis, intraoperative blood loss of (64.5±15.4) ml, postoperative passage of gas on (3.4±0.5) days, first consumption of liquid food after surgery of (3.9±1.1) days, and postoperative hospital stay of (9.1±0.8) days. One patient developed anastomotic stenosis (grade I) after surgery, presenting with mild swallowing obstruction, which returned to normal after dietary adjustment, and there were no cases of secondary surgery. The median follow-up time for the entire group was 4.0 (0.7-7.0) months, during which there were no deaths or tumor recurrence or metastasis, no complications such as anastomotic stenosis or gastric emptying disorders, and no complaints of acid reflux or heartburn. At one month of postoperative follow-up, the reflux symptom index (RSI) score was (3.1±2.9) points, and at three months, the RSI score was (2.4±1.4) points. Conclusions:The application of right-opening single flap valvuloplasty based on tubular stomach for gastrointestinal reconstruction after laparoscopic proximal gastrectomy is safe,feasible,and has satisfactory short-term efficacy.

Objective To investigate the possible association between cross-domain associative memory(AM)impairment and hippocampal subfield volumes in patients with schizophrenia(SCZ).Methods We enrolled 28 SCZ patients from Shanghai Mental Health Center,Shanghai Jiao Tong University School of Medicine,and 28 healthy controls(HCs)between 2019 and 2021.Based on an innovative AM paradigm and automated segmentation,3D-T1 weighted data of the objects were processed with PhiPipe and FreeSurfer.Differences in subfield volums between the two groups were analyzed using ANCOVA,while their relationship with AM scores was assessed using Pearson correlation.Results SCZ patients exhibited significantly poorer AM performance across three conditions compared with HCs.Marginally significant reductions were observed in the total volume of bilateral hippocampus,encompassing both the hippocampal head and body.Significant volume reductions were identified in the bilateral presubiculum and parasubiculum.The volumes of bilateral presubiculum head(r=0.273,P=0.042),parasubiculum(r=0.397,P=0.002),and CA1 head(r=0.382,P=0.004)exhibited positive correlations with cross-domain AM performance.Conclusion The bilateral presubiculum and parasubiculum,as hippocampal subregions significantly associated with cross-modal AM deficits in SCZ,may play a crucial role in the pathology of AM.

Objective To observe the correlation between brain abnormal glucose metabolism and striatal dopaminergic neuron damage in early-stage Parkinson disease(PD)patients.Methods Thirty-two early-stage PD patients(PD group)and 18 healthy individuals(control group)were prospectively enrolled,and 18F-FDG and 18F-9-fluoropropyl-(+)-dihydrotetrabenazine(18 F-FP-DTBZ)PET/MR brain imaging were performed.The degrees of uptake were compared between groups,and the correlation between brain abnormal glucose metabolism and striatal dopaminergic neuron damage was analyzed.Results Compared with control group,18F-FDG PET showed that in PD group glucose metabolism decreased in bilateral frontal and parietal lobes but increased in bilateral putamen,pons and bilateral cerebellum(all P＜0.05),while18 F-FP-DTBZ PET showed that in PD group glucose metabolism decreased in bilateral caudate nucleus,anterior putamen and posterior putamen(all P＜0.05).In PD group,the mean standard uptake value(SUVmean)of putamen was positively correlated with the standard uptake value ratio(SUVR)of contralateral caudate nucleus(r=0.305,P=0.014),while SUVmean of frontal cortex was positively correlated with SUVR of contralateral and symptomatic caudate nucleus(r=0.352,0.324,both P＜0.05)as well as anterior putamen(r=0.300,0.314,both P＜0.05),SUVmean of the partial cortex in parietal lobe was positively correlated with SUVR of contralateral and symptomatic caudate nucleus and contralateral anterior putamen(r=0.329,0.303,0.330,all P＜0.05).Conclusion Brain abnormal glucose metabolism had certain correlation with striatal dopaminergic neuron damage in early-stage PD patients.

Objective:To explore the potential mechanism of action of Xian Fang Huo Ming Yin modified formula(XFHMY)in the treatment of medication-related osteonecrosis of the jaw(MRONJ)through bioinformatics analysis and in vitro and in vivo experiments.Methods:Firstly,the efficacy of XFHMY was evaluated by establishing a mice model of MRONJ induced by zoledronic acid(ZOL);Subsequently,the potential molecular mechanism of XFHMY in the treatment of MRONJ was predicted by using network pharmacology;Lastly,the network pharmacology prediction results were collectively validated through MC3T3-E1 cell proliferation and differentiation experiments,Western blot analysis,and immunohistochemical staining of mouse maxillary bone tissue.Results:Animal experiments showed that,compared to the model group,the XFHMY group exhibited significantly improved wound healing in the tooth extraction socket(P＜0.001),a significant reduction in bone volume fraction and empty lacunae rate in the maxilla(P＜0.0001,P＜0.001),and a significant increase in trabecular separation and osteoclast number(P＜0.01,P＜0.05).Network pharmacology analysis identified 59 common targets,with both GO and KEGG analyses indicating the Wnt/β-catenin signaling pathway as a crucial mechanism for XFHMY in treating MRONJ.Ten key active components,including quercetin,luteolin,and fisetin,were screened,and these compounds demonstrated strong binding affinity with CTNNB1,a core target of this pathway.In vitro experiments revealed that XFHMY(0.25,0.5,1,2,4 mg/mL)promoted MC3T3-E1 cell proliferation(P＜0.0001)and activated the Wnt/β-catenin pathway by upregulating β-catenin and Runx2 protein expression,thereby reversing ZOL-induced inhibition of MC3T3-E1 cell proliferation and differentiation while enhancing both processes.Immunohistochemical analysis of mouse maxillae showed that,compared to the model group,the XFHMY group had significantly increased β-catenin and Runx2 protein expression(P＜0.05,P＜0.01),consistent with the in vitro findings.Conclusion:XFHMY promotes the proliferation and differentiation of osteoblasts through activating the Wnt/β-catenin signaling pathway,which in turn attenuates MRONJ.The novel pharmacological mechanism proposed in this study provides a theoretical basis for the clinical application of XFHMY.
