Objective:To analyse the differences of related genes between serum alpha-fetoprotein (AFP) positive gastric cancer and AFP negative gastric cancer, and the relationship between related genes and prognosis of serum AFP positive gastric cancer.Methods:A total of 1 144 gastric cancer patients undergoing surgery at the 940th Hospital , Joint Logistic Support Force, People's Liberation Army from Jan 2013 to Dec 2018 were retrospectively analyzed. Of them, 47 cases were of AFP positive gastric cancer, and 47 serum AFP negative case were obtained by proper matching method.Results:Forty-seven patients with serum AFP positive gastric cancer, accounting for 4.1% of all gastric cancer patients during the same period. The prognosis of serum AFP negative gastric cancer is better than that of serum AFP positive gastric cancer. The 1-, 3- and 5-year cumulative survival rates were 95.6% vs. 63.8%, 48.9% vs. 23.4% and 26.7% vs. 14.9%, respectively. There were statistical differences in the immunohistochemistry of AFP, HER2, VEGF, GPC3, SALL4, P53 and Ki67 between the two groups ( χ2=67.758, P<0.001; χ2=4.004, P=0.044; χ2=19.299, P<0.001; χ2=5.232, P=0.022; χ2=6.359, P=0.012; χ2=6.224, P=0.013; χ2=5.232, P=0.022). The more co-positive expressions of AFP, GPC3, VEGF and SALL4, the more likely they were to affect pTNM stage, vascular invasion and liver metastasis ( χ2=5.328, P=0.021; P=0.013; χ2=5.887, P=0.015; χ2=3.923, P=0.048). Univariate and multivariate survival analysis of serum AFP positive gastric cancer showed:AFP, GPC3, VEGF and SALL4 were risk factors for AFP positive gastric cancer ( HR=3.700, P=0.036; HR=4.237, P=0.003; HR=3.916, P=0.004; HR=3.412, P=0.001). Conclusions:Serum AFP positive gastric cancer is a rare and highly invasive special type of gastric cancer. AFP, GPC3, VEGF and SALL4 are overexpressed in serum AFP positive gastric cancer, which is correlated with tumor stage, vascular invasion and liver metastasis. The final diagnosis of serum AFP positive gastric cancer still needs immunohistochemical examination. Preoperative serum AFP level is an important basis for AFP positive gastric cancer screening and AFP immunohistochemical examination.

Major depressive disorder (MDD) has become an increasingly serious public health issue, characterized by high incidence and high disability rates. It often coexists with other mental health problems and physical diseases, with a significant negative impact on patients' quality of life. In clinical practice, MDD is considered a heterogeneous disease. The complexity of the pathological mechanisms and the variability in treatment responses lead to a lack of clear therapeutic targets, which complicates the treatment process. In recent years, with advancements in neuroscience, the crucial role of microglia in the pathogenesis of MDD has been revealed. As the main immune cells in the brain, microglia are not only involved in the regulation of neuroinflammation but also play important roles in neurogenesis and neuronal regulation in MDD. This article mainly discusses the role of microglia in the pathophysiological mechanisms of MDD, aiming to provide a theoretical basis for microglia as a potential target for the treatment of MDD.

Objective:To construct a bundled therapy management and practice program for sepsis and explore its clinical application effect.Methods:① Construction of sepsis bundled therapy management and practice program: a project team was established to conduct literature review, select experts, compile and distribute questionnaires, organize, analyze expert opinions, and ensure quality control throughout the research process. From October to November 2022, expert letter consultation was carried out, and questionnaires were distributed and collected by on-site filling and WeChat. The Likert 5-point scale was used to rate each item. ② Clinical application of the protocol: ninety patients with sepsis admitted to the intensive care unit (ICU) of the First Affiliated Hospital of Xinjiang Medical University from January to July 2022 were retrospectively selected as the control group, and routine bundle treatment and nursing strategy for sepsis were adopted. Ninety patients with sepsis admitted from January to July 2023 were prospectively selected as the intervention group. Based on the treatment and nursing strategy of the control group, sepsis bundled therapy management and practice program constructed using the Delphi inquiry method was implemented. The completion rate of 1-hour, 3-hour and 6-hour bundle, the levels of inflammatory indicators at 1, 3, 7 days of treatment, and prognostic indicators were compared between the two groups.Results:① Construction of sepsis bundled therapy management and practice program: the final plan consists of 4 primary indicators, 15 secondary indicators and 34 tertiary indicators. The response rates for both rounds of inquiry questionnaires were 100%. The coefficients of expert authority value were 0.948 and 0.940, respectively. The coefficient of variation for each item was 0-0.287 and 0-0.187, respectively. Kendall's W coefficients were 0.242 and 0.249, respectively, with statistical significances (all P < 0.05). ② Clinical application of the protocol: there were no statistically significant differences in baseline data such as age, gender, infection site, pathogen species, duration of mechanical ventilation, sequential organ failure assessment (SOFA), acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) between the two groups. The completion rate of 1-hour, 3-hour and 6-hour bundle in the intervention group were higher than those in the control group (1-hour bundle completion rate: 53.30% vs. 21.10%, 3-hour bundle completion rate: 92.20% vs. 80.00%, 6-hour bundle completion rate: 88.89% vs. 65.56%, all P < 0.05). The levels of C-reactive protein (CRP), white blood cell count (WBC), procalcitonin (PCT), and interleukin-6 (IL-6) in two groups of patients showed statistically significant differences at different time points, between groups, and in interaction effects. Compared with the control group, the length of ICU stay in the intervention group was significantly shortened [days: 7.00 (4.00, 14.00) vs. 8.00 (7.00, 20.00), P < 0.01], and the hospitalization cost of ICU was significantly reduced [ten thousand yuan: 4.63 (3.36, 6.19) vs. 6.46 (3.32, 11.34), P < 0.05]. The 28-day mortality in the intervention group was lower than that in the control group (33.33% vs. 46.67%), but the difference was not statistically significant ( P > 0.05). Conclusions:The constructed bundled therapy management and practice program for sepsis can improve the completion rate of bundle treatment, shorten the length of ICU stay of sepsis patients, reduce the hospitalization cost in ICU, and have a tendency to reduce the 28-day mortality.

Objective:To explore the impact of parenting style on social anxiety among college students, and examine the mediating effect of core self-evaluation.Methods:From November 2022 to January 2023, a total of 1 126 college students in Harbin were taken as research subjects.Interaction anxiousness scale(IAS), short-egna minnen betraffende upfostran-Chinese(s-EMBU-C) and core self-evaluations scale(CSES) were used for analysis. Data were analyzed using SPSS 26.0 software for correlation analysis and analysis of variance.AMOS 27.0 software was used for mediation effect test.Results:Social anxiety (42.31±8.23) was negatively correlated with positive parenting style (5.44±1.45) ( r=-0.072, P<0.05) and core self-evaluation (32.12±6.01) ( r=-0.350, P<0.01), while positively correlated with negative parenting style (7.40±1.74)( r=0.302, P<0.01). Core self-evaluation was positively correlated with positive parenting style ( r=0.362, P<0.01) and negatively correlated with negative parenting style ( r=-0.346, P<0.01).Parent parenting styles had a significant mean direct effect on social anxiety of college students ( βpositive=0.098, βnegtive=0.222).Mediation analyses indicated that core self-evaluation played a masking role between positive parenting styles and social anxiety, with an absolute value of 90.82% for the ratio of indirect(-0.089) to direct effects(0.098).Core self-evaluation had partial mediating effect on negative parenting styles, with direct effect and indirect effect accounting for 73.03% and 26.97% of the total effect, respectively. Conclusion:Parenting style can either directly affect college students' social anxiety or indirectly through the mediating effect of core self-evaluations, with core self-evaluations playing a masking role in the positive parenting styles pathway.

Objective:To evaluate the influence of manual digitorum sensory stimulation (MDSS) of hemiplegic fingers in median nerve F-wave in stroke patients.Methods:Thirty patients with hemiplegia after stroke, admitted to Department of Rehabilitation Medicine, Second Affiliated Hospital of Anhui Medical University from June 2019 to October 2022 were selected; all patients had thumb flexor modified Ashworth scale (MAS) grading≥1. Hemiplegic MDSS was given; bilateral median nerve F-wave before MDSS and median nerve F-wave at the hemiplegic side immediately after MDSS were recorded.Results:Compared with that at the healthy side before MDSS, amplitude of median nerve F-wave at the hemiplegic side was significantly increased ( P<0.05). Compared with that before MDSS, amplitude of F-wave at the hemiplegic side after MDSS in patients with thumb flexor MAS grading≤2 were significantly decreased ( P<0.05), while that in patients with thumb flexor MAS grading≥3 was significantly increased ( P<0.05). Conclusion:Amplitudes of median nerve F-wave at the hemiplegic side in patients with different thumb flexor MAS grading show that MDSS can not only inhibit the excitability of tonic motor unit related to muscle spasm, but also enhance the excitability of kinetic-motor unit mainly related to explosive power in severe muscle spasm.
