OBJECTIVE: To observe the effect of electroacupuncture combined with enhanced recovery after surgery (ERAS) protocol on promoting intestinal function in patients after gastric cancer surgery. METHODS: Forty-four patients who underwent radical gastrectomy for gastric cancer were randomly divided into an experimental group (22 cases, 3 cases were excluded) and a control group (22 cases, 4 cases were excluded). Both groups received treatment under ERAS protocol, the experimental group was given electroacupuncture at bilateral Neiguan (PC6), Hegu (LI4), Zusanli (ST36) and Quchi (LI11), disperse-dense wave was selected, with frequency of 2 Hz/100 Hz. The control group received placebo electroacupuncture intervention, with the same acupoints as the experimental group, electrode pads were placed on the acupoints without electrical stimulation. Each session lasted 30 min, starting from 1 h after surgery, once every 24 h, until the patient resumed anal flatus. The intestinal sound rate of both groups was observed 24 h before surgery and 24, 48 h after surgery. The bowel sound recovery time (BSRT), time to first anal flatus, time to first defecation, and tolerance to oral enteral nutrition suspension were compared between the two groups. The levels of serum C-reactive protein (CRP), interleukin (IL)-2, IL-4, IL-6, IL-10, IL-12, IL-17, tumor necrosis factor-α (TNF-α) and interferon-γ (IFN-γ) were measured 24 h before surgery and 24 h after surgery in both groups. RESULTS: The intestinal sound rate 24 h after surgery was decreased compared with that 24 h before surgery in the two groups (P<0.05), the intestinal sound rate 24, 48 h after surgery in the experimental group was higher than that in the control group (P<0.05). The BSRT in the experimental group was earlier than that in the control group (P<0.05) .The levels of serum CRP, IL-6, IL-10 24 h after surgery in the experimental group were higher than those 24 h before surgery (P<0.05), while the levels of serum CRP, IL-4, IL-6, IL-10, IFN-γ in the control group were higher than those 24 h before surgery (P<0.05); the levels of serum CRP、IL-4、IFN-γ 24 h after surgery in the experimental group were lower than those in the control group (P<0.05) .The tolerance rate of oral enteral nutrition suspension in the experimental group was 84.2% (16/19), which was higher than 50.0% (9/18) in the control group (P<0.05). CONCLUSION Electroacupuncture combined with ERAS protocol can improve the intestinal motility, shorten the BSRT, enhance the tolerance of oral intake, and reduce inflammatory response in patients after gastric cancer surgery.

Loss-of-function variants of low-density lipoprotein receptor-related protein 5 (LRP5) can lead to reduced bone formation, culminating in diminished bone mass. Our previous study reported transcription factor osterix (SP7)‍-binding sites on the LRP5 promoter and its pivotal role in upregulating LRP5 expression during implant osseointegration. However, the potential role of SP7 in ameliorating LRP5-dependent osteoporosis remained unknown. In this study, we used mice with a conditional knockout (cKO) of LRP5 in mature osteoblasts, which presented decreased osteogenesis. The in vitro experimental results showed that SP7 could promote LRP5 expression, thereby upregulating the osteogenic markers such as alkaline phosphatase (ALP), Runt-related transcription factor 2 (Runx2), and β‍-catenin (P<0.05). For the in vivo experiment, the SP7 overexpression virus was injected into a bone defect model of LRP5 cKO mice, resulting in increased bone mineral density (BMD) (P<0.001) and volumetric density (bone volume (BV)/total volume (TV)) (P<0.001), and decreased trabecular separation (Tb.‍Sp) (P<0.05). These data suggested that SP7 could ameliorate bone defect healing in LRP5 cKO mice. Our study provides new insights into potential therapeutic opportunities for ameliorating LRP5-dependent osteoporosis.

Objective To investigate the association between serum magnesium levels,serum phosphorus concentrations,vascular calcification,and cardiovascular disease mortality in maintenance hemodialysis patients.Methods This study enrolled 200 hemodialysis patients admitted to Nanjing Drum Tower Hospital from May 2020 to May 2022 as subjects,with an additional 200 healthy individuals from the same period selected as a control group.The biochemical indicators between the two groups were compared;their correlations were analyzed.Binary logistic regression was used to investigate the independent factors of serum magnesium and phosphorus levels in relation to vascular calcification and cardiovascular events in maintenance hemodialysis patients.ROC curve analysis was employed to assess the predictive value of serum magnesium and phosphorus for vascular calcification and cardiovascular events.Results The research group's patients exhibited significantly elevated levels of blood phosphorus,calcium-phosphorus product,iPTH,AACS,and 25-(OH)-VitD compared to the control group.In contrast,their blood magnesium and BMP-7 levels were notably lower than those of the control group,with statistical significance(P<0.05).Pearson correlation showed positive correlations between serum magnesium and serum calcium,phosphorus,calcium-phosphorus product,25-(OH)-VitD3,and BMP-7(r=0.385,0.183,0.141,0.131,0.458,P<0.05);between serum calcium and serum phosphorus,calcium-phosphorus product,iPTH,AACS,25-(OH)-VitD3,and BMP-7(r=0.318),correlation(r=0.318,0.311,0.098,0.170,0.277,0.485,P<0.05);between serum phosphorus and calcium-phosphorus product,iPTH,AACS,25-(OH)-VitD3(r=0.362,0.506,0.367,0.461,P<0.05);between calcium-phosphorus product and iPTH,AACS,25-(OH)-VitD3(r=0.542,0.373,0.434,P<0.05);between iPTH and AACS,25-(OH)-VitD3 showing positive correlations(r=0.553,0.616,P<0.05)and a negative correlation with BMP-7(r=-0.373,P<0.05);between AACS and 25-(OH)-VitD3 showing a positive correlation(r=0.402,P<0.05),and a negative correlation with BMP-7(r=-0.155,P<0.05),with statistically significant differences(P<0.05).Statistically significant differences were noted between the two groups in age,diabetes,serum magnesium,serum calcium,serum phosphorus,calcium-phosphorus product,25-(OH)-VitD3,and hs-CRP(P<0.05).Logistic regression analysis showed that age,serum magnesium,serum calcium,serum phosphorus,calcium phosphate product,25-(OH)-vitamin I were all risk factors for cardiovascular disease(CVD)mortality in maintenance hemodialysis(MHD)patients(P<0.05).ROC curve analysis showed that serum magnesium,serum calcium,and serum phosphorus had predictive areas under the curve(AUC)of 0.895,0.802,and 0.851 for CVD mortality in MHD patients,with sensitivities and specificities of 87.5%/98.7%,66.7%/90.8%,and 72.9%/100%,respectively.The combined prediction for CVD mortality in MHD patients showed an AUC of 0.921,with a sensitivity of 81.3%and specificity of 93.4%.Conclusion MHD patients exhibit low blood magnesium levels,elevated serum phosphorus concentrations,and increased calcium-phosphorus product,with complex correlations among these biomarkers.Age,magnesium,calcium,and phosphorus levels were all associated with CVD mortality.ROC curve analysis demonstrates that magnesium,calcium,and phosphorus,both individually and in combination,have high predictive value for CVD mortality risk.

ObjectiveThe potential suitable area for ecological planting， key ecological factors， and suitable range of Polygonatum odoratum in China were analyzed to provide theoretical and scientific guidance for the artificial planting of P. odoratum. MethodA total of 454 geographical distribution records of P. odoratum in China and 118 ecological factors were used in this study. The maximum entropy model （MaxEnt） was adopted to predict the suitable areas of P. odoratum. The key ecological factors and their suitable ranges were analyzed by the jackknife method， contribution rates of ecological factors， and response curves. ResultThe suitable areas of P. odoratum were mainly located in the northwest， north， and northeast of China， the highly suitable areas of which were concentrated in Shaanxi， Shanxi， Gansu， etc. Solar radiation in November （Srad11）， precipitation in July （Prec7）， percentage of evergreen/deciduous needleleaf trees （Class1）， silt content （2-50 μm） mass fraction （SLTPPT）， and annual average temperature （Bio1） were found to be the key ecological factors affecting the suitable distribution of P. odoratum in China. The cumulative contribution rate of solar radiation factors （31.29%）>vegetation factors （25.61%）>soil factors （19.52%）>precipitation factors （11.38%）>temperature factors （8.57%）>topography factors （3.63%）. ConclusionIt is suggested to carry out ecological planting of P. odoratum mainly in Shaanxi （such as Baoji and Ankang Cities and Ningshan， Liuba， and Hua Counties）， Gansu （such as Tianshui City， Gannan Tibetan Autonomous Prefecture， and Liangdang and Huating Counties）， and Shanxi （such as Yangquan， Taiyuan， Fenyang， and Jinzhong Cities， as well as Xingxian County） of China. Solar radiation factors should be given priority in the planting process， followed by vegetation， soil， precipitation， temperature， and topography factors. The range of key ecological factors， namely Srad11， Prec7， Class1， SLTPPT， and Bio1 should be controlled within 8 095.21-10 334.98 （optimum 8 787.50） kJ·m^-2·d^-1， 109.99-223.60 （146.91） mm， 1.00%-9.45% （6.76%-10.68%）， 41.73%-50.35% （46.53%）， and 3.29-16.33 （13.57） °C， respectively.

OBJECTIVE To study the improvement effect and mechanism of Shuhou tongqi formula on intestinal injury in mice with postoperative ileus （POI）. METHODS Mice were randomly divided into sham operation group， model group， positive control group （Mosapride citrate tablets， 1.95 mg/kg）， and Shuhou tongqi formula group （1.88 g/kg）， with 6 mice in each group. Except for the sham operation group， POI model was induced in other groups by typical small intestinal interference. Each group was given relevant drug liquid/water， once a day， for consecutive 2 days. After the last medication， the percentage of carbon powder propulsion in small intestine was detected， and pathomorphological changes in ileum tissue of mice were observed. The serum levels of interleukin-6 （IL-6）， IL-10， tumor necrosis factor-α （TNF-α）， motilin （MTL） and somatostatin （SS） were all detected； the expression levels of Toll-like receptor 4 （TLR4）， nuclear factor κB （NF-κB p65） and p38 mitogen-activated protein kinase （p38 MAPK） were determined in ileal tissue of mice； the gut microbiota of colon contents was analyzed in each group of mice. RESULTS After the intervention of Shuhou tongqi formula， pathological damage such as intestinal wall atrophy and mucosal capillary congestion in ileum tissue were improved significantly； the percentage of carbon powder propulsion and the serum level of IL-10 and MTL were increased significantly （P＜0.05）； however， serum levels of TNF-α， IL-6 and SS， the expressions of TLR4， NF-κB p65 and p38 MAPK were decreased significantly （P＜0.05）. The analysis of gut microbiota showed that Shuhou tongqi formula could significantly increase ACE， Chao1， Shannon and PD indexes， and relative abundance of Akkermansia （P＜0.05）， but decreased relative abundance of Proteobacteria， Ligilactobacillus and Escherichia-Shigella significantly （P＜0.05）. CONCLUSIONS Shuhou tongqi formula can improve intestinal injury and inflammatory reaction of POI mice， the mechanism of which may be associated with inhibiting the activity of TLR4/ NF-κB/MAPK signaling pathway， regulating the levels of gastrointestinal hormones and improving the disturbance of intestinal flora in mice.

OBJECTIVE To explore the safety， effectiveness and cost-effectiveness of a multimodal analgesic regimen in patients who underwent laparoscopic sleeve gastrectomy under the guidance of enhanced recovery after surgery principles. METHODS Data from weight loss patients who underwent laparoscopic sleeve gastrectomy at our hospital were retrospectively collected. The trial group patients received a multimodal analgesic regimen， which included the use of 0.375% ropivacaine for local infiltration of the surgical incision before the end of surgery； intravenous infusion of flurbiprofen axetil 50 mg twice daily； intravenous infusion of methylprednisolone 40 mg once daily and oral administration of extended-release hydrocodone hydrochloride tablets 10 mg twice daily after surgery. The control group patients received a conventional analgesic regimen， which included intravenous infusion of flurbiprofen axetil 100 mg twice daily， with a daily dose twice that of the trial group； and intravenous injection of dexamethasone 5 mg once daily. Propensity score matching was used to balance the baseline data between the two groups. Then the pain scores during movement and at rest at 2， 12， 24 and 36 hours postoperatively， as well as the length of postoperative hospital stay， total length of hospital stay， time to first ambulation after surgery， adverse reactions during hospitalization， total drug costs， and costs of antimicrobial drugs during hospitalization were compared between the two groups. RESULTS The trial group had significantly lower pain scores during movement at 2， 24 and 36 hours postoperatively， and at rest at 2， 12 and 24 hours postoperatively compared to the control group （P＜0.05）. The time to first ambulation after surgery， total length of hospital stay， and length of postoperative hospital stay were significantly shorter in the trial group compared to the control group （P＜0.05）. The incidence of shoulder and back soreness， and costs of antimicrobial drugs were significantly lower in the trial group compared to the control group （P＜0.05）. No statistically significant differences were observed in the total incidence of drug-related adverse reactions and total drug costs during hospitalization between the two groups （P＞0.05）. CONCLUSIONS The multimodal analgesic regimen provides marked pain relief， demonstrates good safety profiles， and has a more economic advantage than the conventional analgesic regimen.

Pharmacological perturbation studies based on protein-level signatures are fundamental for drug dis-covery.In the present study,we used a mass spectrometry(MS)-based proteomic platform to profile the whole proteome of the breast cancer MCF7 cell line under stress induced by 78 bioactive compounds.The integrated analysis of perturbed signal abundance revealed the connectivity between phenotypic behaviors and molecular features in cancer cells.Our data showed functional relevance in exploring the novel pharmacological activity of phenolic xanthohumol,as well as the noncanonical targets of clinically approved tamoxifen,lovastatin,and their derivatives.Furthermore,the rational design of synergistic inhibition using a combination of histone methyltransferase and topoisomerase was identified based on their complementary drug fingerprints.This study provides rich resources for the proteomic landscape of drug responses for precision therapeutic medicine.
