Objective To observe the interventional effects of complex probiotic powder on blood bio-chemical indices and vaginal flora in pregnant women with high risk of gestational diabetes mellitus(GDM). Methods One hundred and ten pregnant women with high risk of GDM recruited from the outpatient clinics of the obstetric department and nutrition department in this hospital were randomly divided into the probiotic intervention group (n=55) and the placebo control group (n=55).The intervention group was given 1 bag of complex probiotic powder per day,and the control group was given 1 bag of placebo powder.The colors,shapes,sizes and tastes of powders in the two groups remained the consistency.The intervention duration in this trial was 23 weeks.The questionnaire survey were conducted at baseline and at the intervention endpoint,and the blood biochemical indexes detections were performed at baseline,after 24-28 weeks of gestation,and after 34-38 weeks of gestation,respectively.In addition,the differences in the composition of the vaginal flora structure between the two groups of high risk pregnant women with GDM were detected at the intervention endpoint.Results A total of 97 cases were eventually included in the statistical analysis.Among them,there were 50 cases in the probiotic intervention group and 47 cases in the placebo control group.At the end of the 23 week intervention,there were no statistically significant differences in fasting blood glucose,red blood cells,hemoglobin,leukocytes,ferritin,total protein,albumin,glutamic transaminase,glutamic oxalate transam-inase and total bilirubin between the probiotic intervention group and placebo control group (P>0.05).In terms of vaginal flora,there was a significant difference in some indicators of α diversity between the probiotic group and placebo control group (P<0.05),and there was no significant difference in β diversity between the two groups (P>0.05).At the level of vaginal flora phyla,there were significant differences in the Firmicutes,Actinobacteria,Desulfobacterota,Deferribacterota,and δ-Myxococcota between the two groups (P<0.05).At the level of vaginal flora genera,the relative abundance of Lactobacillus spp.in the probiotic intervention group was significantly higher than that in the control group (P<0.05).Conclusion Complex probiotic pow-der supplementation may have a limited role in improving blood glucose and other related biochemical indica-tors in high-risk pregnant women with GDM.But it has a certain role in regulating the vaginal micro ecological balance in pregnant women with high risk of GDM.

Objective:To explore the effects of curcumin on the biological characteristics and expressions of NF-κB pathway-related proteins in glucocorticoid-resistant acute lymphoblastic leukemia (ALL) cell line Jurkat.Methods:The drug-resistant ALL cell line Jurkat was selected, and 1 μmol/L dexamethasone was used as the optimal concentration for drug resistance of Jurkat cells, and the cells were passaged and cultured. The cells were divided into 10, 25 and 50 μmol/L curcumin groups, as well as 50 μmol/L pyrrolidinedithiocarbamate (PDTC) group, and control group (equal volume of culture medium without drug was added). The cells in each group were cultured for 72 h, and the cell morphology was observed under an inverted microscope. The CCK-8 method was used to detect the proliferation ability of Jurkat cells, flow cytometry was used to detect the apoptosis ability and cell cycle of Jurkat cells, real-time fluorescence quantitative polymerase chain reaction (qRT-PCR) was used to detect the relative expressions of NF-κB p65, NF-κB p50, IκBα, and A20 mRNA, and Western blotting was used to detect the expressions of NF-κB p65, NF-κB p50, IκBα, caspase-8, caspase-3, bcl-2, and A20 proteins.Results:Jurkat cells were treated with 10, 25, 50 μmol/L curcumin and 50 μmol/L PDTC for 72 h. In the control group, the cell membranes were basically intact, the size was uniform, the cell was round and transparent, and the cell nucleus had uniform fluorescence; a large number of deformed cells and cell fragments were observed in curcumin groups with different concentrations and 50 μmol/L PDTC group, with concentrated and fragmented nuclei and obvious apoptosis. After treating Jurkat cells with different concentrations of curcumin and 50 μmol/L PDTC for 24, 48 and 72 h, respectively, the cell proliferation inhibition rates in curcumin groups with different concentrations and PDTC group were higher than those in the control group (all P < 0.01). The apoptosis rates at 72 h in the control group, 10 μmol/L curcumin group, 25 μmol/L curcumin group, 50 μmol/L curcumin group, and 50 μmol/L PDTC group were (4.9±0.1)%, (99.2±0.1)%, (99.9±0)%, (100.0±0)%, and (100.0±0)%, respectively, and the difference was statistically significant ( F = 2 876 604.40, P < 0.001); compared with the control group, the apoptosis rates in curcumin groups with different concentrations and 50 μmol/L PDTC group were higher, and the differences were statistically significant (all P < 0.01). Compared with the control group, the proportions of S-phase and G 2-phase cells were lower and the proportion of G 1-phase cells was higher in curcumin groups with different concentrations and 50 μmol/L PDTC group at 72 h, and the differences were statistically significant (all P < 0.01). Compared with the control group, the protein and mRNA expressions of NF-κB p65 and NF-κB p50 in curcumin groups with different concentrations and 50 μmol/L PDTC group were lower (all P < 0.01), while the protein expressions of IκBα, caspase-8 and caspase-3 were higher (all P < 0.01), the protein expression of bcl-2 was lower ( P < 0.01), and the protein and mRNA expressions of A20 were higher (both P < 0.01). Conclusions:Curcumin can effectively reverse glucocorticoid resistance and promote apoptosis in Jurkat cells, which may be related to the influence of curcumin on NF-κB pathway-related proteins.

Objective:We aimed to develop a novel visualized model based on nomogram to predict postoperative overall survival.Methods:This was a multicenter, retrospective, observational cohort study, including participants with histologically confirmed gastric and colorectal cancer who underwent radical surgery from 11 medical centers in China from August 1, 2015 to June 30, 2018. Baseline characteristics, histopathological data and nutritional status, as assessed using Nutrition Risk Screening 2002 (NRS 2002) score and the scored Patient-Generated Subjective Global Assessment, were collected. The least absolute shrinkage and selection operator regression and Cox regression were used to identify variables to be included in the predictive model. Internal and external validations were performed.Results:There were 681 and 127 patients in the training and validation cohorts, respectively. A total of 188 deaths were observed over a median follow-up period of 59 (range: 58 to 60) months. Two independent predictors of NRS 2002 and Tumor-Node-Metastasis (TNM) stage were identified and incorporated into the prediction nomogram model together with the factor of age. The model's concordance index for 1-, 3- and 5-year overall survival was 0.696, 0.724, and 0.738 in the training cohort and 0.801, 0.812, and 0.793 in the validation cohort, respectively.Conclusions:In this study, a new nomogram prediction model based on NRS 2002 score was developed and validated for predicting the overall postoperative survival of patients with gastric colorectal cancer. This model has good differentiation, calibration and clinical practicability in predicting the long-term survival rate of patients with gastrointestinal cancer after radical surgery.

Aluminum is a light metal which is rich in the earth's crust and widely used. Recently, the adverse health effects of environmental and occupational aluminum exposure on human have attracted more and more attention. Aluminum exposure has toxic effects on the central nervous system and is believed to be closely related to the development and progression of Alzheimer's disease. The neurotoxic mechanism of aluminum is complex, especially the role of regulated cell death (RCD) in aluminum-induced neuronal death remains to be further studied. RCD refers to all modes of cell death regulated by multiple intracellular signal transduction pathways under physiological and pathological conditions, including apoptosis, necroptosis, autophagy, pyroptosis, and ferroptosis. This review summarized the morphological characteristics and mechanisms of each RCD mode in the process of aluminum-induced neuronal death, and discussed the relationship and transformation between different RCD modes, providing a new scientific basis for future studies on the treatment and intervention of neurotoxicity induced by aluminum exposure.

Objective:To investigate the effect and mechanism of non-selective histone deacetylase (HDAC) inhibitor sodium butyrate (NaB) on neuropathic pain and pain-induced memory impairment in mice.Methods:Forty clean grade male C57BL/6J mice were were divided into 4 groups by random number table method ( n=10 in each group): sham + saline, sham + NaB, chronic constriction injury (CCI)+ saline and CCI + NaB.The mouse CCI model was established by sciatic nerve ligation. Non-selective HDAC inhibitors NaB(300 mg/kg) was intraperitoneally injected into the mice in Sham+ NaB group and CCI+ NaB group once a day 15-28 days after modeling, while the mice in Sham+ saline group and CCI+ saline group were intraperitoneally injected with the same volume of saline. On the 14th and 28th day after operation, the athletic ability was measured by open field test (OFT), the pain behavior was measured by paw withdrawal threshold (PWT) and paw withdrawal latency (PWL), and the memory function was measured by Y-maze. After the behavioral experiment, hippocampus and spinal dorsal horn tissues were taken for the activity of HDAC measurement, and hippocampus tissues were taken for the expression levels of BDNF and PSD95 measurement. SPSS 25.0 software was used for statistical analysis. The data were compared by repeated measurement ANOVA and one-way ANOVA. Results:After treatment with NaB, the interaction effects of the accuracy of spontaneous alternation of PWT, PWL and Y maze in mice were significant( F=21.07, 6.98, 7.79, all P<0.05). Compared with the Sham + saline group, the PWT((0.83±0.30)g, (0.25±0.22)g, (0.24±0.11)g; both P<0.05), the PWL((14.97±4.02)s, (5.99±1.51)s, (6.87±0.90)s; both P<0.05) and the spontaneous alternation in Y maze(71.57±2.80)%, (56.96±0.60)%, (62.86±4.94)%; both P<0.05) in CCI+ Saline group and CCI+ NaB group were lower. After treatment with NaB, compared with CCI + saline group, PWT((0.22±0.13)g, (0.62±0.23)g; P<0.05), PWL((5.62±2.00)s, (8.82±2.13)s; P<0.05)and the accuracy of spontaneous alternation of Y maze were significantly higher ((56.54±7.50)%, (66.35±8.20)%; P<0.05), the HDAC activity in hippocampus((173.40±7.38)%, (122.70±8.40)%; P<0.05)and in spinal cord ((153.40±10.58)%, (111.40±11.40)%; P<0.05)were significantly lower, and the expression of BDNF((0.65±0.06), (0.87±0.43); P<0.05)and PSD95((0.70±0.40), (0.87±0.04); P<0.05)were significantly higher in CCI + NaB group. Conclusion:NaB can improve neuropathic pain and pain-induced memory impairment.The mechanism may be related to the inhibition of HDAC activity and the up-regulation of BDNF and PSD95 expression in hippocampus.

Objective:To investigate the effect of continuous hemoperfusion (HP) on the levels of soluble CD14 isoform (sCD14-st) and neutrophil gelatinase-associated lipocalin (NGAL) on patients with diquat (DQ) poisoning and its significance.Methods:A total of 86 patients with acute DQ poisoning admitted to the department of emergency medicine, Harrison International Peace Hospital Affiliated to Hebei Medical University from May 2018 to August 2021 were enrolled and divided into the intermittent HP group (40 cases) and the continuous HP group (46 cases) according to the random number table method. All patients received basic treatment and continuous veno-venous hemofiltration (CVVH) within 24 hours after admission. On this basis, the intermittent HP group received HP treatment within 2 hours, lasting 2 hours each time for every 8 hours, 3 times in all; the continuous HP group received continued HP treatment until there was no DQ component in urine samples. Serum NGAL levels were detected in all patients before treatment and at 3 hours, 12 hours, 24 hours, 2 days, 3 days, 5 days, and 7 days after treatment. At the same time, serum sCD14-st, blood lactate (Lac), arterial partial pressure of oxygen (PaO 2), serum creatinine (SCr), MB isoenzyme of creatine kinase (CK-MB) and interleukin-18 (IL-18) levels were detected before treatment and at 24 hours, 3 days, and 7 days after treatment. Kaplan-Meier survival curve was drawn to analyze the 28-day survival of patients. Results:Before treatment, there was no significant difference in serum NGAL, sCD14-st, Lac, PaO 2, SCr, CK-MB and IL-18 levels between the two groups. With the prolongation of treatment, the serum levels of NGAL, sCD14-st, Lac, SCr, CK-MB and IL-18 in the intermittent HP group increased at first and then decreased. Serum levels of NGAL, sCD14-st, CK-MB and IL-18 reached their peaks at 24 hours after treatment, and the Lac and SCr levels reached their peaks at 3 days after treatment. In addition, the levels of the above indexes at each time point in the continuous HP group were all significantly lower than those in the intermittent HP group [after 24 hours of treatment: NGAL (μg/L) was 345.90±30.75 vs. 404.24±38.79, sCD14-st (ng/L) was 1 941.88±298.02 vs. 2 656.35±347.93, CK-MB (U/L) was 30.67±9.11 vs. 43.28±8.06, IL-18 (ng/L) was 139.49±16.29 vs. 177.98±27.85; 3 days of treatment: Lac (mmol/L) was 2.98±0.26 vs. 3.72±0.49, SCr (μmol/L) was 125.01±24.24 vs. 156.74±28.88; all P < 0.05]. However, there was no significant difference in PaO 2 levels between the two groups at each time point after treatment. The Kaplan-Meier survival curve showed that the 28-day mortality of patients in the continuous HP group was significantly lower than that in the intermittent HP group [26.09% (12/46) vs. 52.50% (21/40); Log-Rank test: χ2 = 7.288, P = 0.007]. Conclusion:Continuous HP could effectively reduce serum sCD14-st, NGAL levels and 28-day mortality in patients with DQ poisoning, with good curative effect.
