Objective:To investigate the prognosis of patients with initially resectable gastric cancer liver metastasis (GCLM) who were treated by different modalities, and analyze the influencing factors for prognosis of patients.Methods:The retrospective cohort study was conducted. The clinicopathological data of 327 patients with initially resectable GCLM who were included in the database of a nationwide multicenter retrospective cohort study on GCLM based on real-world data from January 2010 to December 2019 were collected. There were 267 males and 60 females, aged 61(54,68)years. According to the specific situations of patients, treatment modalities included radical surgery combined with systemic treatment, palliative surgery combined with systemic treatment, and systemic treatment alone. Observation indicators: (1) clinical characteristics of patients who were treated by different modalities; (2) prognostic outcomes of patients who were treated by different modalities; (3) analysis of influencing factors for prognosis of patients with initially resectable GCLM; (4) screening of potential beneficiaries in patients who were treated by radical surgery plus systemic treatment and patients who were treated by palliative surgery plus systemic treatment. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the rank sum test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. The Kaplan-Meier method was used to calculate survival rate and draw survival curve, and Log-Rank test was used for survival analysis. Univariate and multivariate analyses were conducted using the COX proportional hazard regression model. The propensity score matching was employed by the 1:1 nearest neighbor matching method with a caliper value of 0.1. The forest plots were utilized to evaluate potential benefits of diverse surgical combined with systemic treatments within the population. Results:(1) Clinical characteristics of patients who were treated by different modalities. Of 327 patients, there were 118 cases undergoing radical surgery plus systemic treatment, 164 cases undergoing palliative surgery plus systemic treatment, and 45 cases undergoing systemic treatment alone. There were significant differences in smoking, drinking, site of primary gastric tumor, diameter of primary gastric tumor, site of liver metastasis, and metastatic interval among the three groups of patients ( P<0.05). (2) Prognostic outcomes of patients who were treated by different modalities. The median overall survival time of the 327 pati-ents was 19.9 months (95% confidence interval as 14.9-24.9 months), with 1-, 3-year overall survival rate of 61.3%, 32.7%, respectively. The 1-year overall survival rates of patients undergoing radical surgery plus systemic treatment, palliative surgery plus systemic treatment and systemic treatment alone were 68.3%, 63.1%, 30.6%, and the 3-year overall survival rates were 41.1%, 29.9%, 11.9%, showing a significant difference in overall survival rate among the three groups of patients ( χ2=19.46, P<0.05). Results of further analysis showed that there was a significant difference in overall survival rate between patients undergoing radical surgery plus systemic treatment and patients undergoing systemic treatment alone ( hazard ratio=0.40, 95% confidence interval as 0.26-0.61, P<0.05), between patients undergoing palliative surgery plus systemic treatment and patients under-going systemic treatment alone ( hazard ratio=0.47, 95% confidence interval as 0.32-0.71, P<0.05). (3) Analysis of influencing factors for prognosis of patients with initially resectable GCLM. Results of multivariate analysis showed that the larger primary gastric tumor, poorly differentiated tumor, larger liver metastasis, multiple hepatic metastases were independent risk factors for prognosis of patients with initially resectable GCLM ( hazard ratio=1.20, 1.70, 1.20, 2.06, 95% confidence interval as 1.14-1.27, 1.25-2.31, 1.04-1.42, 1.45-2.92, P<0.05) and immunotherapy or targeted therapy, the treatment modality of radical or palliative surgery plus systemic therapy were independent protective factors for prognosis of patients with initially resectable GCLM ( hazard ratio=0.60, 0.39, 0.46, 95% confidence interval as 0.42-0.87, 0.25-0.60, 0.30-0.70, P<0.05). (4) Screening of potentinal beneficiaries in patients who were treated by radical surgery plus systemic treatment and patients who were treated by palliative surgery plus systemic treatment. Results of forest plots analysis showed that for patients with high-moderate differentiated GCLM and patients with liver metastasis located in the left liver, the overall survival rate of patients undergoing radical surgery plus systemic treatment was better than patients undergoing palliative surgery plus systemic treatment ( hazard ratio=0.21, 0.42, 95% confidence interval as 0.09-0.48, 0.23-0.78, P<0.05). Conclusions:Compared to systemic therapy alone, both radical and palliative surgery plus systemic therapy can improve the pro-gnosis of patients with initially resectable GCLM. The larger primary gastric tumor, poorly differen-tiated tumor, larger liver metastasis, multiple hepatic metastases are independent risk factors for prognosis of patients with initial resectable GCLM and immunotherapy or targeted therapy, the treatment modality of radical or palliative surgery plus systemic therapy are independent protective factors for prognosis of patients with initially resectable GCLM.

Objective To investigate the expression of dopamine(DA),coactivator associated arginine methyltransferase 1(CARM1)and 25-hydroxyvitamin D3[25-(OH)-D3]in peripheral blood of diabetic pa-tients and their relationship with the occurrence of non-alcoholic fatty liver disease(NAFLD).Methods A to-tal of 70 patients with type 2 diabetes mellitus(T2DM)combined with NAFLD treated in this hospital from May 2021 to February 2023 were selected as T2DM with NAFLD group,66 patients with simple T2DM were selected as T2DM group,and 70 healthy people were selected as healthy group.The levels of DA,CARM1 and 25-(OH)-D3 in peripheral blood of each group were compared,and the levels of DA,CARM1 and 25-(OH)-D3 in peripheral blood of T2DM combined with NAFLD patients with different blood glucose control and severity were analyzed.Pearson correlation analysis was used to analyze the correlation between peripheral blood DA,CARM1,25-(OH)-D3 levels and glycosylated hemoglobin A1c(HbA1c),controlled attenuation parameter(CAP).Receiver operating characteristic curve was used to analyze the value of peripheral blood DA,CARM1,25-(OH)-D3 in the diagnosis of severe NAFLD.Results The levels of DA and 25-(OH)-D3 in T2DM with NAFLD group were significantly lower than those in T2DM group and healthy group(P＜0.05),while the level of CARM1 in T2DM with NAFLD group was significantly higher than that in T2DM group and healthy group(P＜0.05).The levels of DA and 25-(OH)-D3 in T2DM group were significantly lower than those in healthy group(P＜0.05),while the level of CARM1 in T2DM group was significantly higher than that in healthy group(P＜0.05).The levels of DA and 25-(OH)-D3 in T2DM with NAFLD patients with poor blood glucose control were significantly lower than those in patients with good blood glucose control(P＜0.05),while the level of CARM1 was significantly higher than that in patients with good blood glucose control(P＜0.05).The levels of DA and 25-(OH)-D3 in patients with severe were significantly lower than those in pa-tients with mild-to-moderate(P＜0.05),while the level of CARM1 was significantly higher than that in pa-tients with mild-to-moderate(P＜0.05).The levels of DA and 25-(OH)-D3in peripheral blood were negative-ly correlated with HbA1c and CAP,and the level of CARM1 was positively correlated with HbA1c and CAP(P＜0.05).The area under curve of CARM1,25-(OH)-D3 and DA were 0.858(95％CI 0.768-0.948),0.922(95％CI 0.856-0.989)and 0.571(95％CI 0.427-0.715),respectively.Conclusion The levels of DA and 25-(OH)-D3 are decreased in peripheral blood of T2DM patients,while the level of CARM1 is in-creased,especially in T2DM patients with NAFLD.DA,CARM1 and 25-(OH)-D3 levels are correlated with blood glucose control and the severity of NAFLD.CARM1 and 25-(OH)-D3 levels have certain application val-ue in the diagnosis of severe NAFLD.

Objective:To examine the impact of varied surgical treatment strategies on the prognosis of patients with initial resectable gastric cancer liver metastases (IR-GCLM).Methods:This is a retrospective cohort study. Employing a retrospective cohort design, the study selected clinicopathological data from the national multi-center retrospective cohort study database, focusing on 282 patients with IR-GCLM who underwent surgical intervention between January 2010 and December 2019. There were 231 males and 51 males, aging ( M(IQR)) 61 (14) years (range: 27 to 80 years). These patients were stratified into radical and palliative treatment groups based on treatment decisions. Survival curves were generated using the Kaplan-Meier method and distinctions in survival rates were assessed using the Log-rank test. The Cox risk regression model evaluated HR for various factors, controlling for confounders through multivariate analysis to comprehensively evaluate the influence of surgery on the prognosis of IR-GCLM patients. A restricted cubic spline Cox proportional hazard model assessed and delineated intricate associations between measured variables and prognosis. At the same time, the X-tile served as an auxiliary tool to identify critical thresholds in the survival analysis for IR-GCLM patients. Subgroup analysis was then conducted to identify potential beneficiary populations in different surgical treatments. Results:(1) The radical group comprised 118 patients, all undergoing R0 resection or local physical therapy of primary and metastatic lesions. The palliative group comprised 164 patients, with 52 cases undergoing palliative resections for gastric primary tumors and liver metastases, 56 cases undergoing radical resections for gastric primary tumors only, 45 cases undergoing palliative resections for gastric primary tumors, and 11 cases receiving palliative treatments for liver metastases. A statistically significant distinction was observed between the groups regarding the site and the number of liver metastases (both P<0.05). (2) The median overall survival (OS) of the 282 patients was 22.7 months (95% CI: 17.8 to 27.6 months), with 1-year and 3-year OS rates were 65.4% and 35.6%, respectively. The 1-year OS rates for patients in the radical surgical group and palliative surgical group were 68.3% and 63.1%, while the corresponding 3-year OS rates were 42.2% and 29.9%, respectively. A comparison of OS between the two groups showed no statistically significant difference ( P=0.254). Further analysis indicated that patients undergoing palliative gastric cancer resection alone had a significantly worse prognosis compared to other surgical options ( HR=1.98, 95% CI: 1.21 to 3.24, P=0.006). (3) The size of the primary gastric tumor significantly influenced the patients′ prognosis ( HR=2.01, 95% CI: 1.45 to 2.79, P<0.01), with HR showing a progressively increasing trend as tumor size increased. (4) Subgroup analysis indicates that radical treatment may be more effective compared to palliative treatment in the following specific cases: well/moderately differentiated tumors ( HR=2.84, 95% CI 1.49 to 5.41, P=0.001), and patients with liver metastases located in the left lobe of the liver ( HR=2.06, 95% CI 1.19 to 3.57, P=0.010). Conclusions:In patients with IR-GCLM, radical surgery did not produce a significant improvement in the overall prognosis compared to palliative surgery. However, within specific patient subgroups (well/moderately differentiated tumors, and patients with liver metastases located in the left lobe of the liver), radical treatment can significantly improve prognosis compared to palliative approaches.

Aim To investigate the protective effect of orcinol glucoside on dexamethasone(DEX)-induced osteoblast injury and its mechanism. Methods Primary osteoblasts were extracted from calvaria of neonatal mice and cultured in medium with DEX(1 μmol•L

ObjectiveTo explore the effect of ovalbumin（OVA）-induced cough variant asthma （CVA） on the intestinal flora of mice， based on the traditional Chinese medicine theory of "exterior-interior relationship between the lung and the large intestine" and 16S ribosomal DNA gene sequencing technology. MethodsTwenty BALB/c female mice were randomly divided into model group and control group， and were sensitized and stimulated with OVA to establish a CVA mouse model. After modeling， the body weight and the cough response of mice were recorded by ammonia water-induced cough method. Hematoxylin-eosin staining was used to observe the pathological changes in the lungs of mice. The feces of mice were collected for 16S rDNA high-throughput sequencing analysis. ResultsCompared with the control group， the mice in the model group were in a poorer general state， being restless， scratching their ears， and losing weight （P<0.01）. The model group mice had increased cough times （P<0.01） and shortened cough latency （P<0.01） in comparison to the control group. Pathological results showed that the model group mice had obvious inflammatory infiltration， thickened airway smooth muscle， and epithelial cell necrosis. 16S ribosomal DNA sequencing showed that the species richness and diversity of the intestinal flora of mice in the model group increased， and the structure of the intestinal flora changed significantly. At the phylum level， the relative abundance of Firmicutes in the model group was decreased， and the relative abundance of Bacteroidetes and Euryarchaeota was increased. At the genus level， the relative abundance of Lactobacillus was decreased in the model group， and the relative abundance of Methanobrevibacter and Prevotellaceae UCG-003 was increased. ConclusionOVA-induced CVA mice had intestinal flora disorder， which provides new idea for the treatment of CVA， and further enriches the traditional Chinese medicine theory of “exterior-interior relationship between the lung and the large intestine”.

OBJECTIVE: To investigate the effect and involved mechanism of RSL3 on ferroptosis action in acute leukemia cells MOLM13 and its drug-resistant cells. METHODS: After MOLM13 treated with RSL3, CCK-8 assay was performed to detect cell viability, flow cytometry was used to detect the reactive oxygen species (ROS) level of the cells, RT-qPCR and Western blot were used to detect the expression of glutathione peroxidase 4 (GPX4). After MOLM13/IDA and MOLM13/Ara-C, the drug-resistant cell lines were constructed, the ferroptosis induced by RSL3 was observed. Bone marrow samples were collected from patients with acute monocytic leukemia. RT-qPCR and Western blot were performed to detect the expression of related genes and proteins involved in ferroptosis pathway. RESULTS: RSL3 significantly inhibited the cell viability of MOLM13 and increased the intracellular ROS level, which were partially reversed by ferrostatin-1. The mRNA and protein expression of GPX4 decreased in MOLM13 treated with RSL3. RSL3 inhibited the viability of MOLM13/IDA and MOLM13/Ara-C cells more strongly than that of non-drug resistant cells, also increased the intracellular ROS level . The cytotoxic effects were partially reversed by ferrostatin-1. The mRNA and protein expressions of GPX4 in MOLM13/IDA and MOLM13/Ara-C cells were higher than those in non-drug resistant cells. The mRNA and protein levels of GPX4 in bone marrow of relapsed/refractory acute mononuclear leukemia patients were higher than those of ordinary acute mononuclear leukemia patients. CONCLUSION RSL3 can induce non-drug resistant cells MOLM13 ferroptosis by inhibiting GPX4 activity. MOLM13/IDA and MOLM13/Ara-C are more sensitive to RSL3 compared with non-drug resistant cells MOLM13, which may be caused by the differences in GPX4 expression. The expressions of GPX4 mRNA and protein in relapsed/refractory acute mononuclear leukemia are higher than those in ordinary acute mononuclear leukemia.

OBJECTIVE: To explore the application value of next generation sequencing (NGS) in preimplantation genetic diagnosis of α/β complex thalassemia couple. METHODS: The coding regions of α-globin genes (HBA1, HBA2) and β-globin gene (HBB) were selected as the target regions. The high-density and closely linked single nucleotide polymorphism (SNP) sites were selected as the genetic linkage markers in the upstream and downstream 2M regions of the gene. After NGS, the effective SNP sites were selected to construct the haplotype of the couple, and the risk chromosome of the mutation carried by the couple was determined. The NGS technology was used to sequence the variations of HBA1, HBA2 and HBB directly and construct haplotype linkage analysis for preimplantation genetic diagnosis. RESULTS: Direct sequencing and haplotype linkage analysis of HBA1, HBA2 and HBB showed that two of the six blastocysts were α/β complex thalassemia, one was β-thalassemia heterozygote, two were α-thalassemias heterozygotes, and one was intermediate α-thalassemia. A well-developed embryo underwent preimplantation genetic diagnosis was implanted into the mother's uterus, and a healthy infant was born at term. CONCLUSION Preimplantation genetic diagnosis can be carried out by NGS technology in α/β complex thalassemia couples, and abortion caused by aneuploid embryo selection can be avoided.

BACKGROUND: Shenyankangfu Tablet (SYKFT) is a Chinese patent medicine that has been used widely to decrease proteinuria and the progression of chronic kidney disease. OBJECTIVE: This trial compared the efficacy and safety of SYKFT, for the control of proteinuria in primary glomerulonephritis patients, against the standard drug, losartan potassium. DESIGN, SETTING, PARTICIPANTS AND INTERVENTION: This was a multicenter, double-blind, randomized, controlled clinical trial. Primary glomerulonephritis patients, aged 18-70 years, with blood pressure ≤ 140/90 mmHg, estimated glomerular filtration rate (eGFR) ≥ 45 mL/min per 1.73 m MAIN OUTCOME MEASURES: The primary outcome was change in the 24-hour proteinuria level, after 48 weeks of treatment. RESULTS: A total of 735 participants were enrolled. The percent decline of urine protein quantification in the SYKFT group after 48 weeks was 8.78% ± 2.56% (P = 0.006) more than that in the losartan 50 mg group, which was 0.51% ± 2.54% (P = 1.000) less than that in the losartan 100 mg group. Compared with the losartan potassium 50 mg group, the SYKFT plus losartan potassium 50 mg group had a 13.39% ± 2.49% (P < 0.001) greater reduction in urine protein level. Compared with the losartan potassium 100 mg group, the SYKFT plus losartan potassium 100 mg group had a 9.77% ± 2.52% (P = 0.001) greater reduction in urine protein. With a superiority threshold of 15%, neither was statistically significant. eGFR, serum creatinine and serum albumin from the baseline did not change statistically significant. The average change in TCM syndrome score between the patients who took SYKFT (-3.00 [-6.00, -2.00]) and who did not take SYKFT (-2.00 [-5.00, 0]) was statistically significant (P = 0.003). No obvious adverse reactions were observed in any group. CONCLUSION: SYKFT decreased the proteinuria and improved the TCM syndrome scores of primary glomerulonephritis patients, with no change in the rate of decrease in the eGFR. SYKFT plus losartan potassium therapy decreased proteinuria more than losartan potassium therapy alone. TRIAL REGISTRATION NUMBER NCT02063100 on ClinicalTrials.gov.

Objective:To study the soil physical and chemical properties， microorganisms， and metabolites in different culture environments of Gastrodia elata， so as to provide scientific basis for subsequent cultivation of G. elata in multiple environments. Method:The tubersphere soil of G. elata cultured in different environments was collected for analyzing the soil nutrients， microbial numbers， and metabolite differences using the agrochemical method， plate-count method， and gas chromatography-time-of-flight mass spectrometry （GC-TOF-MS）-based non-targeted metabonomic approach. Result:The analysis of soil physical and chemical properties revealed the highest soil moisture， pH， available potassium， and available phosphorus in the spinney and the highest electrical conductivity， total nitrogen， alkali-hydrolyzable nitrogen， and organic matter in the pinewood. As demonstrated by the quantitative analysis of soil microorganisms， the cultivable microorganisms were bacteria， actinomycetes， and fungi， with the bacterial population and total microbial biomass in the spinney and the number of fungi and actinomycetes in the barren slope detected to be the largest. The ratio of bacteria to fungi （B/F value） in the pinewood was the highest， while that in the barren slope was the lowest. The results of metabonomic research demonstrated that the compositions and quantities of soil metabolites in the spinney （Z group）， pinewood （S group）， and barren slope （HD group） varied. Through comparisons between S and Z groups， between HD and Z groups， as well as between HD and S groups by orthogonal partial least squares discriminant analysis （OPLS-DA）， 18， 35， and 24 differential metabolites were separately screened out， and the Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment analysis yielded 5， 9， and 13 metabolic pathways. There existed a significant causal relationship of the soil physical and chemical properties and microbial numbers with the metabolites. Conclusion:The soil physical and chemical properties， microbial numbers， and metabolite changes differed significantly in different culture environments of G. elata， which were sorted by the suitability in a descending order as follows： spinney > pinewood >barren slope. The soil physical and chemical properties and microbial numbers are the crucial factors driving changes in soil metabolites， suggesting that regulating the soil physical and chemical characteristics and microbial characteristics in the culture environment is an important mechanism for maintaining the G. elata-soil-microbial symbiotic system.
