Objective To analyze the value of systemic inflammatory indicators in diagnosing schizo-phrenia and their correlation with disease condition severity and cognitive dysfunction.Methods A total of 47 patients with schizophrenia visited and treated in this hospital from October 2021 to March 2023 were selected as the study subjects,and 47 healthy volunteers during the same period served as the control group.The morn-ing fasting venous blood was collected in all research subjects,and the blood routine and biochemical indicators were measured.The SII,SIRI,NHR and LHR were calculated.The receiver operating characteristic(ROC)curve was used to analyze the diagnostic value of SII,SIRI,NHR and LHR in the patients with schizophrenia.The correlation adopted the Pearson correlation analysis.Results The levels of SII,SIRI,NHR and LHR in the schizophrenia group were significantly increased compared with the control group,and the difference was statistically significant(P＜0.05).The ROC curve analysis demonstrated that the area under the curve(AUC)of SII,SIRI,NHR and LHR detection alone in diagnosing schizophrenia were 0.683,0.686,0.774 and 0.766 respectively.AUC of their combination detection was 0.886.SII was positively correlated with the gen-eral symptoms and the positive and negative symptom scale(PANSS)total score,and negatively correlated with the spatial structure,linguistic function and delayed memory(P＜0.05);SIRI was positively correlated with the negative symptoms,general symptom and PANSS total score,and negatively correlated with the im-mediate memory,spatial structure,linguistic function,attention;NHR was positively correlated with the nega-tive symptoms,positive symptoms,general symptoms and PANSS total score,and negatively correlated with immediate memory,linguistic function,attention and delayed memory(P＜0.05).LHR was positively corre-lated with the positive symptoms,general symptoms and PANSS total score,and negatively correlated with the spatial structure,linguistic function,attention and delayed memory(P＜0.05).Conclusion SII,SIRI,NHR and LHR combined detection has higher diagnostic value for the patients with schizophrenia.Further-more,the SII,SIRI,NHR and LHR levels are closely correlated with the disease condition severity and cogni-tive function impairment degree.

Objective To investigate the role of squalene epoxidase(SQLE)knockout in anti-tumor effect vial im-proving CD8+T cell infiltration in melanoma tumor microenvironment.Methods Both immunodeficient and immu-nocompetent mice were inoculated with SQLE knockout B16F10 cells to determine the cell-autonomous and non-au-tonomous regulation of malignancy.Antibody blockade,Luminex multiplex assays,and flow cytometry were em-ployed to explore the impact of SQLE gene knockout on the secretion of cytokines/chemokines and immune cell in-filtration.Bioinformatics analysis was conducted to validate the correlation between SQLE expression and immune infiltration as well as clinical prognosis in melanoma patients.Results Compared with immunodeficient mice,SQLE knockout significantly inhibited melanoma proliferation in immunocompetent mice and prolonged their surviv-al.SQLE knockout induced the secretion of cytokines and chemokines from tumor cells,improved CD8+T cell in-filtration in the tumor microenvironment,thereby potentiating anti-tumor immunity.Bioinformatics analysis sugges-ted a significant correlation between SQLE and its corresponding immune infiltration markers with the prognosis of melanoma patients.Conclusion SQLE regulates anti-tumor immunity by controlling cytokines and chemokines re-leasing in tumor microenvironment,thus holding promise as a novel tumor immunotherapy target and efficacy predic-tion molecular indicator.

Objective: To explore the practicability and reproducibility of judgment method and assessment indexes for the end point of double eyelid surgery using 4+ 1 photography in supine position. Methods: From 2017 October to 2018 October, 158 patients were included and randomly divided into 2 groups. Photos were taken by 4 + 1 photography in supine position of 79 patients, while other 79 patients in control group were evaluated by traditional observation. By 4+ 1 photography in supine position, the surgeon stood at the head side of the patient, taking photos with eyes movement: looking straight forward, looking up, looking downward and eye-closed. It was to observe the upper eyelid creases, upper and lower tissues of double eyelid creases, and upper and lower eyelid margo palpebrae. In addition, the surgeon looked from patient′s feet to observe the indexes such as upper margo palpebrae, to make a decision whether the surgery could finish. In control group, the surgeon observed the upper eyelid creases, upper and lower tissues of double eyelid creases and upper and lower eyelid margo palpebrae. The patient has to sit if necessary. Results: All 158 patients were performed double eyelid surgery successfully. Average times of valuating end point was 1.20 by 4+ 1 Photography in supine position, and 1.53 in control group. The operation time of 4+ 1 photography group is (151.65±21.58) s, and control group were (241.53±33.53) s. The satisfaction level was increased to 89.87% in 4+ 1 photography group, compared to 78.48% in control group. Conclusions The 4+ 1 Photography method is simple and easy to practice. The observation indexes are accurate and comprehensive. It is useful in determining the end point of double eyelid plasty in supine position.
