OBJECTIVE: To evaluate the safety and effectiveness of robot-assisted percutaneous coronary intervention (R-PCI) compared to traditional manual percutaneous coronary intervention (M-PCI). METHODS: This prospective, multicenter, randomized controlled, non-inferior clinical trial enrolled patients with coronary heart disease who met the inclusion criteria and had indications for elective percutaneous coronary intervention. Participants were randomly assigned to either the R-PCI group or the M-PCI group. Primary endpoints were clinical and technical success rates. Clinical success was defined as visually estimated residual post-percutaneous coronary intervention stenosis < 30% with no 30-day major adverse cardiac events. Technical success in the R-PCI group was defined as successful completion of percutaneous coronary intervention using the ETcath200 robot-assisted system, without conversion to M-PCI in the event of a guidewire or balloon/stent catheter that was unable to cross the vessel or was poorly supported by the catheter. Secondary endpoints included total procedure time, percutaneous coronary intervention procedure time, fluoroscopy time, contrast volume, operator radiation exposure, air kerma, and dose-area product. RESULTS: The trial enrolled 152 patients (R-PCI: 73 patients, M-PCI: 79 patients). Lesions were predominantly B2/C type (73.6%). Both groups achieved 100% clinical success rate. No major adverse cardiac events occurred during the 30-day follow-up. The R-PCI group had a technical success rate of 100%. The R-PCI group had longer total procedure and fluoroscopy times, but lower operator radiation exposure. The percutaneous coronary intervention procedure time, contrast volume, air kerma, and dose-area product were similar between the two groups. CONCLUSIONS For certain complex lesions, performing percutaneous coronary intervention using the ETcath200 robot-assisted system is safe and effective and does not result in conversion to M-PCI.

OBJECTIVE: To investigate the safety and efficacy of avatrombopag（AVA） combined with rhIL-11 in treating thrombocytopenia induced by chemotherapy in acute myeloid leukemia. METHODS: The clinical information of 8 patients in the real world who received avatrombopag combined with rhIL-11 in cancer treatment-induced thrombocytopenia(CTIT) after AML chemotherapy were retrospectively analyzed, and at the same time, 8 patients who received rhIL-11 only in CTIT after AML chemotherapy served as the control group, A preliminary observation was to summarize and compare the therapeutic efficacy and adverse effects between the two groups. RESULTS: D3 and D7 platelet counts were not significantly different between the observation group and the control group after treatment. The platelet counts in the observation group was significantly higher than those of the control group on the 10th day after treatment (P < 0.01). The adverse reactions, such as weakness, abdominal pain, fatigue, nausea and edema after treatment were mild in the observation group and the control group. Except for one patient in the observation group who had a history of cerebral infarction before the onset of the disease and was routinely taking antiplatelet drugs, no thrombosis events occurred in the patients in the observation and control groups during the period of administration of the drug, and the total incidence rate of adverse reactions was not significantly different between the two groups. CONCLUSION The combination of AVA and rhIL-11 can enhance platelet recovery in CTIT of AML patients after chemotherapy. Compared with the rhIL-11 alone group, the platelet recovery time in AVA+rhIL-11 group was significantly shorter, the platelet count on the 10th day after drug administration was significantly higher. No statistically significant difference in the total incidence rate of adverse reactions was observed between rhIL-11 alone group and AVA+rhIL-11 group.

This article aims to explore the effect and mechanism of Liujunzi Pills on the intestinal microbiota of rats with spleen Qi deficiency syndrome. The raw Rhei Radix et Rhizoma water extract(1 g·mL~(-1)) was used to prepare spleen Qi deficiency rat models. A total of 44 SD male rats were randomly divided into a control group, a model group, Liujunzi Pills groups at high(3.24 g·kg~(-1)), medium(1.62 g·kg~(-1)), low(0.81 g·kg~(-1)) doses, and Shenling Baizhu San(2.50 g·kg~(-1)) group. The drug effect was evaluated by observing the following aspects: spleen index, fecal water content, body weight, and intestinal propulsion index. Gut microbiota analysis and 16S rRNA gene sequencing were conducted on feces. Enzyme-linked immunosorbent assay(ELISA) and UV spectrophotometry were used to detect interleukin-1β(IL-1β) and adenosine triphosphate(ATP) levels in small intestine tissues. Hematoxylin-eosin staining and transmission electron microscopy were employed to observe changes in intestinal pathology and microstructure. The results show that, compared with the control group, fecal moisture content is significantly increased while spleen index, body weight, and intestinal propulsion index are significantly reduced in rats of the model group, indicating the successful establishment of the model. The above symptoms can be improved by both Shenling Baizhu San and Liujunzi Pills. Compared with the control group, in the model group, the gut microbiota abundance is changed with an unbalanced development: the abundance of beneficial bacteria within the Bacteroidetes phylum is reduced, accompanied by a significantly decreased Shannon index, and reduced signal levels of nicotinamide adenine dinucleotide phosphate(NADPH)-related enzymes relevant to mitochondria. However, Liujunzi Pills and Shenling Baizhu San can significantly improve the Bacteroidetes phylum abundance in gut microbiota, microbial diversity, and NADPH activity in the model group. Additionally, compared with the control group, the ATP level is decreased and the IL-1β level is increased in small intestinal tissues of the model group, with shorter small intestinal epithelial villi and decreased mitochondrial number. The above symptoms can be improved by Liujunzi Pills and Shenling Baizhu San. In conclusion, Liujunzi Pills can treat spleen Qi deficiency syndrome by enhancing mitochondrial function to regulate gut microbiota balance and diversity.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To explore the association between the systemic immune-inflammation index (SII) and obesity metabolic phenotypes, as well as metabolic features in children and adolescents.Methods:A cross-sectional study was conducted using the random cluster sampling method from March 2023 to May 2024. Children and adolescents aged 9-17 years in Guangzhou were surveyed through questionnaires, physical measurements, and blood tests. According to BMI and metabolic status, participants were classified into normal-weight groups [metabolically healthy normal weight (MHNW) and metabolically unhealthy normal weight (MUNW)] and overweight/obese groups [metabolically healthy overweight/obese (MHO/O) and metabolically unhealthy overweight/obese (MUO/O)]. After natural log-transformation of SII values (lnSII), multinomial logistic regression was used to assess the association between SII and obesity metabolic phenotypes, while binary logistic regression was applied to assess the relationship between SII and metabolic phenotypes in the overweight/obese subgroup. Linear regression model and restricted cubic spline (RCS) were employed to examine the relationship between SII and metabolic features among the entire population.Results:A total of 3 749 participants were included. After adjusting for covariates, for every unit increase in lnSII, the risk of MHO/O and MUO/O increased by 93% ( OR=1.93, 95% CI: 1.56-2.40, P<0.001) and 156% ( OR=2.56, 95% CI: 2.02-3.25, P<0.001), respectively. In the overweight/obesity subgroup, for every unit increase in lnSII, the risk of MUO/O increased by 37% ( OR=1.37, 95% CI: 1.01-1.87, P=0.045). Linear regression model and RCS showed that lnSII was positively correlated with systolic blood pressure (SBP) and diastolic blood pressure (DBP) (SBP: β=1.39, 95% CI: 0.67-2.11, P<0.001; DBP: β=1.27, 95% CI: 0.79-1.75, P<0.001). lnSII also had a non-linear relationship with triglyceride ( Pnonlinear=0.032) and high-density lipoprotein cholesterol ( Pnonlinear=0.002). Conclusion:Elevated SII levels are associated with unfavorable obesity metabolic phenotypes, higher blood pressure, and altered lipid profiles in children and adolescents. SII may be a potential driving factor for metabolic heterogeneity in children and adolescents.

Objective:To assess the application effects of an energy-restricted diet combined with high-protein, high-dietary-fiber meal replacement powder and probiotics in overweight/obese adults.Methods:It was a randomized controlled trial. A consecutive sample of 150 overweight/obese adults who underwent physical examinations at the Health Care Center of the First Hospital of Hebei Medical University between November 2021 and March 2022. The participants were randomly assigned into the combined group, the high-protein group, and the common group (50 participants per group) using a random number table method. All three groups of subjects received weight loss health education, energy-restricted diet, and interventions with meal replacement powder and probiotics (or probiotic placebo). The combined group was given high-protein and high-dietary fiber meal replacement powder and probiotics. The high-protein group was given high-protein meal replacement powder and probiotic placebo. The common group was given ordinary meal replacement powder and probiotic placebo. The meal replacement powder was packaged in 35 g per bag, with main components of varying amounts of protein, fat, carbohydrates, vitamins, and trace elements. Both the probiotic powder and the probiotic placebo came in 2 g sachets. The primary components of probiotic powder were various Bifidobacterium, Lactobacillus and excipients, while the main component of probiotic placebo was excipients. The meal replacement powder and the probiotic powder or probiotic placebo were taken twice a day for a total of 12 weeks, one sachet of each time, followed by a 4-week follow-up. The body weight, body mass index, body fat mass, abdominal circumference and hip circumference were measured before the trial (week 0) and at the end of weeks 2, 4, 8, 12, and 16. The change rates of each indicator were calculated. Biochemical indicators, trace elements, and 25-hydroxyvitamin D levels were measured at the end of week 0, 4, 8, and 12. A product evaluation questionnaire was conducted at the end of week 12. A total of 19 cases dropped out due to various reasons. Finally, 46 cases in the combined group, 42 cases in the high-protein group, and 43 cases in the common group were included in the analysis. Paired-samples t test, Kruskal-Wallis H test, one-way analysis of variance, and Mann-Whitney U test were used to compare the differences in weight-loss and maintenance effects, safety and patient acceptance among the three intervention groups, and to analyze the application effect of the energy-restricted diet combined with high-protein and high-dietary fiber meal replacement powder plus probiotics in overweight/obese adults. Results:Among the 131 overweight/obese adults included in the analysis, there were 57 males and 74 females, with a mean age of (37.30±8.33) years. By the end of the week 12, the body mass index [26.87(25.77, 30.38) vs 29.61(27.96, 33.09) kg/m2; 27.10(24.70, 31.37) vs 29.40(27.20, 34.17) kg/m2; 27.98(26.43, 30.12) vs 29.88(28.22, 31.93) kg/m2] and body fat masses [22.15(17.70, 30.15) vs 30.75(25.63, 35.40) kg; 23.35(19.12, 28.70) vs 29.45(26.20, 37.05) kg; 26.80(24.10, 31.60) vs 30.00(26.00, 34.70) kg] in the combined group, the high-protein group and the common group were all lower than those at baseline (week 0) (all P<0.05). At the end of the week 12, the change rates of body fat mass and body mass index in the combined group were both higher than those in the high-protein group and the common group [(25.98%±9.58%) vs (23.88%±11.15%) and (9.35%±11.00%), 9.29%(7.23%, 11.58%) vs 7.96% (5.51%, 10.92%) and 5.77% (2.68%, 10.03%)] (all P<0.05). At the end of the week 12, the body fat mass in the combined group and the high-protein group were both lower than that in the common group [22.15(17.70, 30.15), 23.35(19.12, 28.70) vs 26.80(24.10, 31.60) kg] (both P<0.05). At the end of the week 12, the decreased values of uric acid and high-sensitivity C-reactive protein in the combined group were both higher than those in the high-protein group and the common group [17.15(13.02, 23.45) vs 1.50(0.22, 28.60) and 4.20(0.15, 19.95) μmol/L, 0.43(0.24, 0.60) vs 0.21(0.06, 0.43) and 0.28(-0.04, 0.88) mg/L](both P<0.05). No serious adverse events were observed during the intervention period and at the end of the intervention. In the product evaluation questionnaire, the combined group scored higher than the high-protein group and the common group on items such as usage frequency, taste, satiety, willingness to continue use, willingness to recommend to others, and willingness to purchase [4(3, 4) vs 3(3, 4) and 3(2, 4) points, 4(3, 4) vs 3(3, 4) and 3(2, 4) points, 4(3, 4) vs 3(3, 4) and 3(3, 3) points, 4(3, 4) vs 3(3, 4) and 3(3, 4) points, 4(3, 4) vs 3(3, 4) and 3(3, 3) points, 3(3, 4) vs 3(3, 4) and 3(2, 3) points] (all P<0.05). Conclusion:An energy-restricted diet combined with high-protein, high-dietary-fiber meal replacement powder and probiotics demonstrates superior weight-loss and weight-maintenance effects in overweight/obese adults, with high safety and great user acceptability.

ObjectiveTo investigate the potential machanism of Xiaozhong Zhitong Mixture （消肿止痛合剂， XZM） in the treatment of diabetes foot ulcer （DFU）. MethodsFifty SD rats were randomly divided into blank group， model group， XZM group， inhibitor group， XZM plus inhibitor group （combination group）， with 10 rats in each group. Except for the blank group， rats were fed with high-sugar， high-fat， high-cholesterol diet， intraperitoneally injected with streptozotocin， and subjected to skin defect to establish DFU model. After successful modeling， the XZM group and the combination group were given 1 ml/（100 g·d）of XZM by gavage， while the blank group， model group， and inhibitor group were all given an equal volume of 0.9% sodium chloride injection by gavage. Thirty minutes later， the inhibitor group and the combination group were intraperitoneally injected with 5 mg/（kg·d） of Notch1 inhibitor DAPT. All groups were treated once a day. After 14 days of administration， the skin tissue from the dorsal foot of the blank group rats and wound tissue from the other groups were collected. The pathological changes of granulation tissue in the wound were detected using hematoxylin eosin （HE） staining. The microvascular density （MVD） in wounds was detected through immunohistochemical staining. Real time fluorescence quantitative polymerase chain reaction （RT-PCR） and western blotting were used to detect the mRNA and protein levels of Notch1 homolog （Notch1）， Delta-like ligand 4 （Dll4）， Delta-like ligand 4 （VEGF）， and angiopoietin 2 （Ang-2）， respectively. ResultsHistological results showed that the epidermal structure in the dorsal foot skin tissue of the rats in the blank group was intact. In the wound tissue of the model group， the epidermis exhibited excessive keratinization， vacuolar cytoplasm， and a large number of inflammatory cells infiltrating the tissue， while in the XZM group， a large amount of scab formation was observed in the epidermis， with no significant inflammatory cell infiltration and a noticeable increase in fibroblasts. In the combination group and the inhibitor group， partial epidermal scab formation was observed in the wound tissue with a small amount of inflammatory cell infiltration. Compared to those in the blank group， the MVD in the wound tissue increased in the model group， as well as the mRNA expression and protein levels of Notch1 and Dll4， while VEGFA and Ang-2 mRNA expression and protein levels significantly decreased （P＜0.05 or P＜0.01）. Compared to those in the model group， the MVD in the wound tissue of all medication groups significantly increased， and the mRNA and protein levels of Notch1 and Dll4 decreased， while VEGFA and Ang-2 mRNA expression and protein levels increased （P＜0.05 or P＜0.01）. Compared to the XZM group， the inhibitor group and the combination group showed decreased MVD in wound tissue， increased Notch1 and Dll4 mRNA and protein levels， and decreased expression of VEGFA and Ang-2 mRNA and proteins （P＜0.05 or P＜0.01）. ConclusionXZM can effectively promote wound healing in DFU rats， and its mechanism of action may be related to the inhibition of Dll4/Notch1 signaling pathway in the wound tissue， therey promoting angiogenesis.

Objective To investigate the prognostic factors of leptomeningeal metastasis of lung adenocarcinoma without driving gene.Methods Retrospectively collected the clinical data of lung adenocarcinoma patients with leptomeningeal metastasis without driving gene in the affiliated Cancer Hospital of Xinjiang Medical University from January 1,2011 to December 31,2023,and followed up their survival time.Results Among the 58 patients with leptomeningeal metastasis of lung adenocarcinoma,the survival time was 0-38.0months,the median overall survival time(mOS)was 5.0months,and the one-year survival rate was 25.9％.33 patients received antineoplastic therapy,and the survival time of patients receiving antineoplastic therapy was significantly longer than that of patients with-out antineoplastic therapy(8.0months vs 2.0months,P=0.006).Among them,12 patients received chemotherapy combined with whole brain radiotherapy.The mOS of patients who received chemotherapy combined with radiotherapy and those who did not receive chemother-apy combined with radiotherapy were 6.0 and 3.0months(P=0.098).21 patients received only systemic chemotherapy,and the mOS of patients receiving chemotherapy alone and chemotherapy combined with radiotherapy were 6.0 and 8.0months(P=0.497).The survival time of patients less than 60 years old at the time of diagnosis of LM was prolonged(8.0months vs 2.0months,P=0.011).Whether pa-tients received antineoplastic therapy or not was an independent prognostic factor for patients with lung adenocarcinoma LM(HR=0.489,95％CI:0.281-0.849).Conclusion Age＜60 years old and antineoplastic therapy can prolong the prognosis of patients with lepto-meningeal metastasis of lung adenocarcinoma with negative driver gene,and antineoplastic therapy is an independent factor affecting the prognosis of patients.

Objective To evaluate the effects of transcatheter aortic valve replacement(TAVR)on left ventricular reverse remodeling(LVRR)and outcomes in patients with mixed aortic valve disease(MAVD)and predominant aortic stenosis(AS).Methods Patients undergoing TAVR at our center between January 2020 and December 2022 were enrolled consecutively.Propensity score matching(PSM)(1∶1 ratio)was used to reduce selection bias.Transthoracic echocardiography(TTE)was used to monitor left ventricular ejection fraction(LVEF)and other structural parameters over time.The study outcome was a composite of cardiovascular death and rehospitalization due to cardiovascular causes.Linear mixed-effects models and logistic regression were utilized for comparing echocardiographic changes across groups and identifying independent risk factors for no-LVRR,respectively.Results After PSM,126 patients were included.MAVD group exhibited larger structural parameters(left ventricular end-systolic/end-diastolic diameter and volume,left ventricular mass index)and a lower left ventricular ejection fraction(LVEF)(all P＜0.05).However,more pronounced improvements in left ventricular structure and hemodynamics were observed during follow-up.Multivariate logistic regression analysis indicated that the left ventricular mass index(LVMI)was an independent predictor of left ventricular reverse remodeling(LVRR)after TAVR,whereas persistent moderate or greater mitral regurgitation(MR)and paravalvular leak(PVL)significantly reduced the incidence of LVRR.During a median follow-up period of 23 months,a total of 31 endpoint events occurred,and there was no statistically significant difference in long-term prognosis between the two groups(Log-rank P=0.330).Conclusions Compared to patients in the AS group,those in the MAVD group exhibited more severe left ventricular remodeling before TAVR.However,more significant LVRR was observed during postoperative follow-up.Additionally,the long-term prognosis was comparable between the two groups.

Purpose Discover new prostate cancer-related single nucleotide variants.Methods Tissue wax blocks from 21 prostate cancer patients who underwent radical surgery and had relatively complete clinical data were collected for somatic mutation detection to analyze new mutated genes associated with prostate cancer.The levels of cor-responding proteins in the urine of prostate cancer patients were tested according to the results of the selected genes.Results All 21 prostate cancer patients showed obvious somatic mutations,and the mutation types were dominated by C＞T and G＞A.The number of somatic mutations was 521,of which 27 genes had high mutation proportions(≥2 ca-ses),including ZSWIM6(5/21),FOXA1(4/21),SPTA1(2/21),FAM47C(2/21),FLG2(2/21),PRSS3(2/21),TP53(2/21),FLG(2/21),UBR4(2/21),and the mutations occurring in ZSWIM6 were all deletion muta-tions,and the mutations occurring in FOXA1 were missense mutations,deletion mutations,and deletion insertion mu-tations.The urinary levels of UPF1,SPTA1,and IDH1 proteins of the 10 prostate cancer patients were significantly different than those of the healthy controls.Correlation analysis showed that FOXA1 was positively correlated with UBR4(r=0.669,P=0.001),SPTA1 was positively correlated with FLG2(r=1.000,P＜0.001),FAM47C was positively correlated with PRSS3(r=1.000,P＜0.001),and there was a significant positive correlation between TP53 and FLG(r=1.000,P＜0.001).ZSWIM6 and FOXA1 were not correlated with biochemical recurrence.SP-TA1 mutation affected progression-free survival(PFS)[(66.0±0)months vs(30.0±7.8)months,P=0.008].FAM47C was positively correlated with PFS[(66.0±0)months vs(19.0±0)months,P＜0.001].ZNF676 was correlated with PFS[(66.0±0)months vs(26.0±5.0)months,P=0.008].FLG2 was correlated with PFS[(66.0±0)months vs(30.0±7.8)months,P=0.008].PRSS3 was correlated with PFS[(66.0±0)months vs(19.0±0)months,P＜0.001].Conclusion All 21 prostate cancer patients harbored somatic mutations,including ZSWIM6(5/21)and FOXA1(4/21)mutations.SPTA1,FAM47C,ZNF676,FLG2,and PRSS3 may be associated with prognosis.
