Objective:To investigate the expression, prognosis, and role of G protein-coupled receptor kinase-interacting protein 1 (GIT1) in patients with hepatocellular carcinoma (HCC) tumor micro environments.Methods:Clinical data of 140 cases who underwent complete HCC surgical resection from January 2015 to December 2021 in Subei People's Hospital affiliated to Yangzhou University, Jiangsu Province, were included. Tumor tissue and adjacent tissue samples were collected for immunohistochemical analysis. The patients were divided into a high expression group and a low expression group according to the expression of GIT1. Cox regression was used to analyze the risk factors for prognosis in patients with HCC. Fifteen pairs of cancer tissues and adjacent tissues were randomly matched for quantitative polymerase chain reaction (RT-PCR), western blot (WB), and immunohistochemical analysis. GITI knockout or overexpression cell lines of human hepatoma cell lines HepG2, HuH7 and MHCC97-H, and mouse hepatoma cell line Hepa 1-6 were constructed. The effects on M2 macrophage polarization were analyzed by flow cytometry. A mice tumor model was constructed. The growth curve of tumor tissue overexpressing GIT1 was plotted. Bioinformatics analysis of the Cancer Genome Atlas (TCGA) data was performed using OncoLnc, Kaplan-Meier Plotter, UALCAN, and GEPIA databases to explore the differential expression of GIT1 in HCC patients and its effect on prognosis.Results:Bioinformatics analysis showed that the expression level of GIT1 was significantly higher in HCC tissues than in normal liver tissues ( P<0.05). RT-PCR and WB experiments showed that GIT1 was highly expressed in HCC. The follow-up results showed that high expression of GIT1 was associated with poor prognosis in patients with HCC. The high expression of GIT1 was an independent risk factor for the prognosis in patients with HCC ( HR=2.562, 95% CI: 0.231-0.704, P<0.05). Functional enrichment analysis combined with TIMER database analysis found that GIT1 expression level was associated with multiple immune cell infiltrations in HCC, but the correlation coefficient with macrophage infiltration was the highest ( r=0.545, P<0.001). Mice tumorigenesis experiments showed that the tumor volume of GIT1-overexpressing mice was significantly increased ( P<0.05). Additionally, flow cytometry indicated that after GIT1 overexpression, there was a low degree of M1 infiltration/polarization (wild type: 5.06%±0.11%, overexpression type: 4.09%±0.04%; P<0.05) and a high degree of M2 infiltration/polarization (wild type: 10.20%±0.33%, overexpression type: 14.7%±0.12%; P<0.05). Conclusion:GIT1 serves as a prognostic biomarker in HCC, promoting tumor progression through its high expression and enhances M2 macrophage infiltration.

This work was supported by Science and Technology Program of Health and Family Planning Commission of Jiangxi Province (No.20161106) Abstract Objective: To investigate the prognostic value of subventricular zone (SVZ) invasion in glioma patients. Methods: The clini-cal data of 175 patients with glioma diagnosed based on pathology in Jiangxi Province Cancer hospital between January 2010 and July 2015 were analyzed retrospectively. There were 59 cases of World Health Organization (WHO) gradeⅡ, 59 cases of WHO gradeⅢ, and 57 cases of WHO gradeⅣat the first diagnosis. There were 75 cases of SVZ invasion (SVZ+) and 100 cases of SVZ non-invasion (SVZ-) according to preoperative magnetic resonance imaging. The survival outcomes of both cohorts were compared using the Log-rank test. The correlation between the recurrence pattern and SVZ involvement was analyzed using Chi-square tests. Results: The me-dian follow-up time was 63 months. The 5-year overall survival (OS) and progression-free survival (PFS) rates were 42.2% and 37.5%, respectively. These were 20.9% and 15.3% in the SVZ+group, compared with 57.1% and 44.1% in the SVZ-group, respectively (P<0.001 and P<0.001, respectively). The SVZ+group had fewer cases of total resection, larger lesions (maximum diameter greater than 5.0 cm), and more cases of gradeⅣ(P<0.001, P<0.001, and P=0.018, respectively). There were 89 cases of recurrence. The total recur-rence rate was 62.7% in the SVZ+group, compared with 42.0% in the SVZ-group (P=0.007); the distant recurrence rates were 21.3% and 7.0% (P=0.004), respectively. Conclusions: SVZ invasion is a poor prognostic factor for OS and PFS in gliomas, which is positively correlated with a low total resection rate, large lesions, and gradeⅣlesions, and increases the probability of total recurrence and dis-tant recurrence.

Objective:To assess the prognostic factors of World Health Organization(WHO)grade Ⅱ gliomas.Methods:A total of 146 patients diagnosed with WHO grade Ⅱ gliomas were treated at Jiangxi Province Tumor Hospital between June 1997 and April 2015,in-cluding 90 gross total resections(GTRs)and 56 partial resections.According to the 2007 WHO grading system of gliomas,there were 96 astrocytomas,30 oligodendrogliomas,and 20 oligoastrocytomas.Results:The median follow-up time was 88 months.Five-year overall survival(OS)and progression-free survival(PFS)rates were 75.7% and 60.0%,respectively,and 10-year OS and PFS rates were 57.4% and 37.8%,respectively.Univariate analysis of OS revealed statistically significant differences in age,sex,subventricular zone (SVZ) invasion, peritumoral edema, residual tumor volume, preoperative tumor size and numbers, and the extent of resection (P<0.05). Compared with astrocytoma patients, oligodendroglioma patients had better OS and PFS (P=0.040 and 0.049, respectively). Among those factors,sex,SVZ invasion,residual tumor volume,preoperative tumor numbers,and the extent of resection were like-wise significant for PFS (P<0.05). Multivariate analysis revealed that the extent of resection, SVZ invasion, and peritumoral edema were independent prognostic factors for OS(P<0.05)and the extent of resection and tumor numbers were independent prognostic fac-tors for PFS(P<0.05).Sixty patients developed recurrences,including 53 tumor bed failures and 7 intracranial disseminations.Conclu-sions:The extent of resection,SVZ invasion and peritumoral edema may be independent prognostic factors for OS in low-grade glio-mas.Postoperative radiotherapy would improve PFS for patients who underwent GTRs.The major pattern of failure was tumor bed re-currence.

Objective To observe the clinical efficacy of general balance therapy in treating cervical spondylosis of nerve root type.Method Totally 120 patients with cervical spondylosis of nerve root type were randomized into a treatment group and a control group, 60 cases in each group. The treatment group was intervened by general balance therapy (balance needling plus balance tuina manipulations), while the control group was by ordinary acupuncture and tuina manipulations. The cervical movement ranges were observed before and after the treatment, and the clinical efficacies were compared between the two groups. Result The cervical movement ranges (forward flexion, backward extension, lateral flexion, and turning range) were significantly changed in both groups after the treatment (P<0.05). The cervical movement ranges of the treatment group were significantly different from that of the control group (P<0.05). The total effective rate was 95.0% in the treatment group versus 85.0% in the control group, and the difference was statistically significant (P<0.01).Conclusion General balance therapy is an effective method in treating cervical spondylosis of nerve root type.

Objective To investigate the relationship between surgical timing and outcomes of aneurysmal subarachnoid hemorrhage (aSAH).Methods The patients with aSAH retrospectively received clipping or endovascular embolization.Their demographic and clinical data were collected.The modified Rankin Scale (mRS) was used to evaluate the outcomes at 6 month after procedure.Univariate and multivariate logistic regression analyses were used to determine the risk factors that influencing clinical outcomes of patients.Results A total of 198 patients with aSAH were enrolled,118 had good outcome (mRS score0-2),80 had poor outcome (mRS score ＞2; 20 of them died); 32 were early operation (operated within 2 d after onset) and 166 were late operation.Univariate analysis showed that the proportions of hypertension (29.66％ vs.52.50％ ; x2 =10.464,P =0.001),cerebral infarction (11.86％ vs.35.00％ ;x2 =15.269,P ＜0.001),cerebral hemorrhage (9.32％ vs.31.25％ ;x2 =15.410,P ＜0.001),Fisher grade 3-4 (22.88％ vs.47.50％ ; x2 =13.104,P ＜ 0.001),Hunt-Hess grade Ⅳ to Ⅴ (19.49％ vs.52.50％ ;x2 =23.557,P ＜0.001),cerebral vasospasm (5.93％ vs.25.0％ ;x2 =14.719,P ＜0.001),hydrocephalus (5.08％ vs.17.50％ ;x2 =8.093,P =0.004),and late operation (78.81％ vs.91.25％ ; x2 =5.442,P =0.020) in patients of the good outcome group were significantly higher than those of the poor outcome group.Multivariatelogistic regression analysis showed that Fisher grade 3 to 4 (odds ratio [OR] 9.13,95％confidence interval [CI] 2.98-13.45; P ＜0.001),Hunt-Hess grade Ⅳ to Ⅴ (OR 6.86,95％ CI 1.57-12.34; P＜0.001),accompanied with hydrocephalus (OR 2.59,95％ CI 1.17-4.31; P=0.024),and late operation (OR 2.17,95％ CI 1.12-3.95; P=0.029) were the independent risk factors for patients with poor clinical outcomes.The univariate analysis for both early operation and late operation groups showed that only the good outcome rate of the early operation group was significantly higher than that of the late operation group (78.13％ vs.56.2％ ;x2 =5.442,P =0.020),and there were no significant differences in the incidences of rebleeding (6.25％ vs.13.25％; x2=1.235,P=0.266),cerebral vasospasm (12.50％ vs.19.28％;x2 =0.042,P=0.834),and hydrocephalus (12.50％ vs.9.64％;x2 =0.242,P=0.623).Conclusion Early operation may significantly improve the outcomes in patients with aSAH.
