ObjectiveTo investigate the effects of Chaihu and Longgu Mulitang （CLMT） on hippocampal neural damage in the mouse model of depression via the extracellular signal-regulated protein kinase （ERK）/cAMP-response element-binding protein （CREB） signaling pathway. MethodsSeventy-eight male C57BL/6 mice were randomly allocated into normal control， model， low/medium/high-dose （2.89， 5.78， and 11.56 g·kg^-1， respectively） CLMT， and paroxetine （10 mg·kg^-1） groups. A depression model was established by chronic unpredictable mild stress （CUMS） combined with social isolation. Behavioral tests were carried out to evaluate depressive-like behaviors. Hematoxylin-eosin staining and Nissl staining were performed to assess hippocampal morphology and neuronal damage. Immunofluorescence was employed to detect glial fibrillary acidic protein （GFAP） and ionized calcium-binding adapter molecule 1 （Iba1）. Real-time PCR was employed to measure the mRNA levels of ERK and CREB. Western blot was employed to determine the expression of ERK/CREB pathway proteins and brain-derived neurotrophic factor （BDNF） in the hippocampal tissue. Molecular Operating Environment （MOE） software was used for molecular docking to evaluate the interactions between CLMT components and target proteins. ResultsCompared with the normal control group， the model group showed decreased sucrose preference （P0.01）， increased tail-suspension immobility time （P0.01）， decreased activity in the central region of the open field test （P0.01）， and decreased activity in the middle and open-arm region of the elevated plus maze test （P0.01）. The hippocampal area in the model group showed wrinkled cells and a reduction in the number of cells， neurons with reduced sizes and Nissl bodies， enhanced fluorescence intensity of GFAP and Iba1 （P0.01）， and down-regulated expression of phosphorylated （p）-ERK， p-CREB， and BDNF （P0.05， P0.01） and mRNA levels of ERK and CREB （P0.01）. Compared with the model group， the CLMT group showed increased body weight （P0.05， P0.01）， restored cell morphology， with only a small number of ruptured cells， normal neuronal structure and morphology with obvious nuclei and abundant Nissl bodies， weakened fluorescence intensity of GFAP and Iba1 （P0.05， P0.01）， up-regulated mRNA levels of ERK and CREB （P0.05， P0.01） and protein levels of phosphorylated （p）-ERK， p-CREB， and BDNF in the hippocampal tissue （P0.05， P0.01）. The results of molecular docking indicated that nine active ingredients in CLMT had good binding affinity with ERK and CREB. ConclusionCLMT may ameliorate the hippocampal nerve injury in the mouse model of depression by regulating the ERK/CREB pathway.

Objective To investigate the relationship of miRNA gene polymorphisms with blood pressure(BP)responses to the sodium and potassium diet intervention.Methods In 2004,we recruited 514 participants from 124 families in seven villages of Baoji,Shaanxi Province,China.All subjects were given a three-day normal diet,followed by a seven-day low-salt diet,a seven-day high-salt diet,and finally a seven-day high-salt and potassium supplementation.A total of 19 miRNA single nucleotide polymorphisms(SNPs)were selected for analysis.Results Throughout the sodium-potassium dietary intervention,the BP of the subjects fluctuated across all phases,showing a decrease during the low-salt period and an increase during the high-salt period,followed by a reduction in BP subsequent to potassium supplementation during the high-salt diet.MiR-210-3p SNP rs 12364149 was significantly associated with systolic BP(SBP),diastolic BP(DBP)and mean arterial pressure(MAP)responses to low-salt diet.MiR-4638-3p SNP rs6601178 was significantly associated with SBP while miR-26b-3p SNP rs115254818 was significantly associated with MAP responses to low-salt intervention.In addition,miR-26b-3p SNP rs115254818 was significantly correlated with SBP,DBP and MAP responses to high-salt intervention.MiR-1307-5p SNPs rs1 1191676 and rs2292807 were associated with SBP and MAP responses to high-salt diet.MiR-4638-3p SNP rs6601178,miR-210-3p SNP rs12364149,miR-382-5p SNP rs4906032 and rs4143957 were significantly associated with SBP response to high-salt diet.In addition,miR-26b-3p SNP rs115254818 was significantly associated with SBP,DBP and MAP responses to potassium supplementation.MiR-1307-5p SNPs rs11191676,rs2292807,and miR-19a-3p SNP rs4284505 were significantly associated with SBP responses to high-salt and potassium supplementation.Conclusion miRNA gene polymorphisms are associated with BP response to sodium and potassium,suggesting that miRNA genes may be involved in the pathophysiological process of salt sensitivity and potassium sensitivity.

Objective:In this study, we aimed to compare the short-term safety of two digestive tract reconstruction techniques, laparoscopic total abdominal overlap anastomosis and laparoscopic-assisted end-to-side anastomosis, following radical resection of Siewert Type II adenocarcinoma of the esophagogastric junction.Methods:In this retrospective cohort study, we analyzed relevant clinical data of 139 patients who had undergone radical surgery for Siewert Type II esophagogastric junction adenocarcinoma. These included 89 patients treated at the First Affiliated Hospital of Air Force Medical University from November 2021 to July 2023, 36 patients treated at the First Affiliated Hospital of Xi'an Jiaotong University from December 2020 to June 2021, and 14 patients treated at the Yuncheng Central Hospital in Shanxi Province from September 2021 to November 2022. The group consisted of 107 men (77.0%) and 32 women (23.0%) of mean age 62.5±9.3 years. Forty-eight patients underwent laparoscopic total abdominal overlap anastomosis (overlap group), and 91 laparoscopic-assisted end-to-side anastomosis (end-to-side group). Clinical data, surgical information, pathological findings, postoperative recovery, and related complications were compared between the two groups.Results:There were no significant differences in general clinical data between the overlap and end-to-side anastomosis groups (all P>0.05), indicating comparability. There was no significant difference in operation time (267.2±60.1 minutes vs. 262.8±70.6 minutes, t=0.370, P=0.712). However, the intraoperative blood loss in the overlap group (100 [50, 100] mL) was significantly lower compared to the end-to-side group (100[50, 175] mL, Z=2.776, P=0.005). Compared to the end-to-side group, longer distances between the tumor and distal resection margin proximal(1.7±1.0 cm vs. 1.3±0.9 cm, t=2.487, P=0.014) and the tumor and distal resection margin (9.5±2.9 cm vs. 7.9±3.5 cm, t=2.667, P=0.009) were achieved in the overlap group. Compared with the end-to-side group, the overlap group achieved significantly earlier postoperative ambulation (1.0 [1.0, 2.0] days vs. 2.0 [1.0, 3.0] days, Z=3.117, P=0.002), earlier time to first drink (4.7±2.6 days vs. 6.2±3.0 days, t=2.851, P=0.005), and earlier time to first meal (6.0±2.7 days vs. 7.1±3.0 days, t=2.170, P=0.032). However, the hospitalization costs were higher in the overlap group (113, 105.5±37, 766.3) yuan vs. (97, 250.2±27, 746.9) yuan; this difference is significant ( t=2.818, P=0.006). There were no significant differences between the two groups in postoperative hospital stay, total number of lymph nodes cleared, or time to first postoperative flatus (all P>0.05). The incidence of surgery-related complications was 22.9%(11/48) in the overlap group and 19.8% (18/91) in the end-to-side group; this difference is not significant (χ2=0.187, P=0.831). Further comparison of complications using the Clavien-Dindo classification also showed no significant differences ( Z=0.406, P=0.685). Conclusions:Both laparoscopic total abdominal overlap anastomosis and laparoscopic-assisted end-to-side anastomosis are feasible for radical surgery for Siewert Type II esophagogastric junction adenocarcinoma. Laparoscopic total abdominal overlap anastomosis achieves longer proximal and distal resection margins and better postoperative recovery; however, end-to-side anastomosis is more cost-effective.

Objective To investigate the effect of evolocumab combined with levocarnitine after emergency percutaneous coronary intervention (PCI) in patients with acute ST-segment elevation myocardial infarction (STEMI). Methods A total of 120 STEMI patients were selected and randomly divided into treatment group (60 cases) and control group (60 cases). The control group was given STEMI basic treatment plus levocarnitine, and the treatment group was given evolocumab on the basis of the control group. The therapeutic effectiveness, coronary artery microcirculation [B-type natriuretic peptide (BNP), left ventricular ejection fraction (LVEF)], coronary arteriole status[Thrombolysis in Myocardial Infarction (TIMI) risk score, preprotein converting enzyme subtilysin 9 (PCSK9) and low density lipoprotein cholesterol (LDL-C)] and incidence of adverse reactions were compared between the two groups before and after treatment. Results After treatment, the total effective rate of treatment group was significantly higher than that of control group (P < 0.05). After treatment, BNP level in two groups was significantly lower than before treatment, and the level in the treatment group was significantly lower than that in the control group (P < 0.05); LVEF in the two groups was significantly higher than before treatment, and the treatment group was significantly higher than the control group (P < 0.05). After treatment, the TIMI risk score of the two groups was significantly decreased, and the treatment group was significantly lower than the control group (P < 0.05). The levels of PSCK9 and LDL-C in the two groups were significantly lower than before treatment, and the treatment group was significantly lower than the control group (P < 0.05). After treatment, there was no significant difference in the incidence of adverse reactions between the two groups (P>0.05). Conclusion Evolocumab combined with levocarnitine can improve cardiac function and coronary microcirculation in STEMI patients after emergency PCI, and has high safety.

Objective To investigate the expression of(glutathione S-Transferase Omega-1,GSTO1)in cervical cancer tissue and its correlation with patient survival time,and to explore the impact of GSTO1 N-glycosylation on proliferation,migration,invasion,and epithelial-mesenchymal transition of cervical cancer.Methods By using immunohistochemistry,the expression levels of GSTO1 in tumor cells of 82 cervical cancer patients were detected,and the correlation between GSTO1 expression and clinical pathological features was analyzed.Kaplan-Meier meth-od was used to plot survival curves and evaluate the impact of GSTO1 expression in cervical cancer tissues on pa-tient survival time.Univariate and multivariate Cox regression analyses were performed to assess the independent prognostic factors influencing cervical cancer prognosis.The NetNGlyc 1.0 Server database predicted potential N-glycosylation modification sites of GSTO1(Asn55,Asnl35,Asn190).The cervical cancer cells(HeLa)were transfected with GSTO1 N-glycosylation site mutation vectors at positions 55,135,and 190,as well as GSTO1 wild-type vector and empty vector.Stable transfected cells were selected using puromycin.Western blot experi-ments were performed to assess the effectiveness of lentiviral interference.The effects of GSTO1 N-glycosylation site mutations on proliferation,migration,and invasion of HeLa cells were evaluated using EdU proliferation assay,wound healing assay,and Transwell assay.The effect of GSTO1 N-glycosylation site mutations on the epithelial-mesenchymal transition of HeLa cells was detected using the Western blot experiment.Results Immunohistochem-istry results revealed high expression of GSTO1 in cervical cancer tissues.The expression rate of GSTO1 was signifi-cantly higher in cervical cancer tissues with deep stromal invision≥1/2,lymphovascular space invasion,and lymph node metastasis(P＜0.05).Moreover,high expression of GSTO1 was associated with poorer overall surviv-al.After N-glycosylation site-specific mutation of GSTO1,the cell count of proliferation,migration,and invasion in HeLa cells significantly decreased(P＜0.05).The Western blot results showed that N-glycosylation site mutation of GSTO1 significantly inhibited the epithelial-mesenchymal transition of HeLa cells.Conclusion The expression of GSTO1 in cervical cancer tissues is associated with stromal infiltration depth,lymphovascular space invasion and lymph node metastasis,and it is also correlated with shorter patient survival time.Site-specific mutations in GSTO1 N-glycosylation significantly inhibit the proliferation,migration and epitheli al-mesenchymal transition of HeLa cells.

【Objective】 Corin, a transmembrane serine protease that can cleave atrial natriuretic peptide precursor (pro-ANP) into atrial natriuretic peptide with smaller bioactive molecules, participates in the pathophysiological process of hypertension and cardiac hypertrophy. The purpose of this study was to explore the relationship of Corin gene variation with blood pressure responses to sodium and potassium dietary interventions. 【Methods】 In 2004, we recruited 514 participants from 124 families in 7 villages of Baoji, Shaanxi Province, China. All the subjects received a 3-day normal diet, a 7-day low-salt diet, a 7-day high-salt diet, and finally a 7-day high-salt and potassium supplementation. Fifteen single nucleotide polymorphisms (SNPs) of Corin gene were selected for final analysis. 【Results】 SNPs rs12509275 were significantly associated with diastolic blood pressure (DBP) response to low-salt diet, while rs3749584 was associated with pulse pressure (PP) response to low-salt diet.SNP rs3749584 and rs10517195 were significantly associated with PP response to high-salt diet. In addition,rs17654278 were significantly associated with systolic blood pressure (SBP) response to high-salt and potassium supplementation, rs2271037 was significantly correlated with DBP responses to high-salt and potassium supplementation, and rs4695253, rs12509275, rs2351783, rs36090894 were significantly associated with PP response to high-salt and potassium supplementation. 【Conclusion】 Corin gene polymorphisms were associated with blood pressure response to sodium and potassium, suggesting that Corin gene may be involved in pathophysiological process of salt sensitivity and potassium sensitivity.

Chemoimmunotherapy has been approved as standard treatment for triple-negative breast cancer (TNBC), but the clinical outcomes remain unsatisfied. Abnormal epigenetic regulation is associated with acquired drug resistance and T cell exhaustion, which is a critical factor for the poor response to chemoimmunotherapy in TNBC. Herein, macrophage-camouflaged nanoinducers co-loaded with paclitaxel (PTX) and decitabine (DAC) (P/D-mMSNs) were prepared in combination with PD-1 blockade therapy, hoping to improve the efficacy of chemoimmunotherapy through the demethylation of tumor tissue. Camouflage of macrophage vesicle confers P/D-mMSNs with tumor-homing properties. First, DAC can achieve demethylation of tumor tissue and enhance the sensitivity of tumor cells to PTX. Subsequently, PTX induces immunogenic death of tumor cells, promotes phagocytosis of dead cells by dendritic cells, and recruits cytotoxic T cells to infiltrate tumors. Finally, DAC reverses T cell depletion and facilitates immune checkpoint blockade therapy. P/D-mMSNs may be a promising candidate for future drug delivery design and cancer combination therapy in TNBC.

ObjectiveTo explore the typical behavior characteristics of children with autism in symbolic play and the value of Symbolic Play Test (SPT) in the early identification of autism. MethodsFrom November, 2021 to September, 2022, a total of 260 children with language problems were collected from Department of Children's Health Care of Binzhou Medical University Hospital. A total of 193 children with autism were as observation group and 67 normal children were as control group. All children played symbolic games. The typical behavioral characteristics of children with autism in SPT were explored, and a reliability and validity analysis based on the results of SPT was conducted. They were assessed with the adaptive and personal social scores of Gesell Development Scale, and the correlation of the scores of Gesell Development Scale and the score of SPT was analyzed. ResultsThe Cronbach's α coefficient of SPT of children with autism was 0.835 to 0.935, and the total score of SPT, the scores of surrogate object, fictional attribute and fictional object were positively correlated with each other (r > 0.607, P < 0.001). The SPT scores decreased in the observation group (t > 9.615, P < 0.001), and SPT score positively correlated with adaptability and personal-social development quotient (r > 0.609, P < 0.001). ConclusionTypical behavior of children with autism can be reflected in symbolic play, and SPT can provide clues for early identification of autism.
