Objective To evaluate the correlation between cyclin B1 (CCNB1) gene expression and the prognosis of lung adenocarcinoma. Methods Oncomine, STRING, Human Protein Atlas, The Cancer Genome Atlas and other databases as well as Kaplan-Meier method, Cox regression, receiver operating characteristic (ROC) curve and Spearman correlation analysis were used to verify the effect of CCNB1 on patients with lung adenocarcinoma. Results CCNB1 was highly expressed in lung adenocarcinoma, and the high expression was correlated with T stage (P=0.001), N stage (P<0.001), pathological stage (P<0.001) and gender (P=0.008). Univariate Cox regression analysis showed that the expression of CCNB1, T stage, N stage, M stage and pathological stage were the factors affecting the overall survival rate of patients with lung adenocarcinoma (P<0.05); multivariate Cox regression analysis showed that the expression of CCNB1 and T stage were independent risk factors for overall survival of patients with lung adenocarcinoma (P<0.05). Kaplan-Meier analysis showed that high expression of CCNB1 was associated with shorter overall survival [hazard ratio (HR)=1.60, 95% confidence interval (CI) (1.20, 2.14), P=0.002], disease-specific survival [HR=1.68, 95%CI (1.16, 2.44), P=0.006] and progression-free interval [HR=1.42, 95%CI (1.09, 1.85), P=0.009]. The ROC curve showed that CCNB1 might be a potential diagnostic molecule for lung adenocarcinoma [area under the curve=0.980, 95%CI (0.967, 0.993)]. Spearman correlation analysis showed that CCNB1 expression was positively correlated with the infiltration of T helper cells 2 (rs=0.805, P<0.001) and T helper cells (rs=0.103, P=0.017), and negatively correlated with the infiltration of natural killer cells (rs=−0.195, P<0.001), macrophages (rs=−0.134, P=0.002), and T cells (rs=−0.092, P=0.033). Conclusion CCNB1 is highly expressed in lung adenocarcinoma compared with normal tissues, which is related to poor prognosis and may provide a potential therapeutic target for patients with lung adenocarcinoma.
ObjectiveTo study the infiltration situation of breast cancer surface skin, and explore the characteristics of infiltration of breast cancer surface skin at the molecular level. MethodsNested reverse transcription-polymerase chain reaction technique was used to detect the expressions of human mammaglobin(hMAM)mRNA in 15 cases of hyperplasia of mammary gland tissues, 15 cases of breast fibroadenoma tissues, and 60 cases of breast cancer tissues and their corresponding tumor surface skins. The relationship of the hMAM mRNA expression in the surface skins of breast cancer tissue to its clinicopathologic characteristics was analyzed. ResultsThe hMAM mRNA positive expressions in the breast fibroadenoma tissues, hyperplasia of mammary gland tissues, and breast cancer tissues were 40.00%(6/15), 53.33%(8/15), and 83.33%(50/60), respectively, which in the breast cancer tissues was significantly higher than that in the breast fibroadenoma tissues or hyperplasia of mammary gland tissues(P < 0.05). There was no hMAM mRNA positive expression in the surface skin of fibroadenoma or hyperplasia of mammary gland tissues, but there was 3(5.00%)cases of the hMAM mRNA positive expressions in the breast cancer surface skin. The hMAM mRNA positive expression in the breast cancer surface skin was not related with the patient age, tumor diameter, and tumor staging(P > 0.05), but was related with axillary lymph nodes metastasis and distance from tumor to nipple less than 4 cm(P < 0.05). ConclusionsThe hMAM mRNA highly expresses in breast cancer tissue and it has a certain value in the diagnosis of infiltration of breast cancer surface skin. The patients with axillary lymph node metastasis and distance from tumor to nipple less than 4 cm are more susceptible to infiltration of breast cancer surface skin.
Objective To analyze the relationship between the expression of carbonic anhydrase 3 (CA3) in breast cancer tissues, its prognostic potential and the number of immune cells by a variety of online databases. Methods GEPIA2.0 and TIMER databases were used to analyze the difference of CA3 mRNA expression in breast cancer tissues. Bc-GenExMinerv4.7 database was used to analyze the difference of CA3 mRNA expression in breast cancer subcategories. Kaplan-Meier plotter, Bc-GenExMinerv4.7 and PrognoScan databases were used to analyze the effect of CA3 mRNA expression levels on prognosis of patient. LinkedOmics database was used to analyze of the biological behavior involved in CA3 co-expressed genes. TIMER database was used to analyze the relationship between CA3 mRNA expression and immune cells infiltration in breast cancer tissues. Results The expression of CA3 mRNA in breast cancer tissues was lower than that in normal breast tissues (P<0.05), and the expression levels of CA3 mRNA were higher in ER negative (P<0.05), PR negative (P<0.05), HER2 negative (P<0.05) and no lymphatic metastasis (P<0.05). In addition, the expression level of CA3 in breast cancer patients with high Ki67 expression was lower (P<0.05) and closely related to SBR and NPI grade (P<0.05). Breast cancer patients with low expression of CA3 mRNA had lower overall survivall, recurrence free survival, and disease free survival ( P<0.05). Ten of the top 50 positively correlated co-expressed genes screened out had low risk ratio (P<0.05), and 11 of the top 50 negatively correlated co-expressed genes screened out had high risk ratio (P<0.05). The expression of CA3 mRNA was positively correlated with CD4+ T cells and CD8+ T cells in breast cancer tissues (rs=0.175, P<0.001; rs=0.137, P<0.001), and negatively correlated with T cell failure markers LAG3, TIM-3 and PVRL2 (rs=–0.100, P<0.01; rs=–0.143, P<0.001; rs=–0.082, P<0.05). Conclusions The low expression of CA3 mRNA in breast cancer tissues is correlated with the occurrence, development and prognosis of breast cancer. CA3 can be used as a potential independent prognostic marker for breast cancer and may be related to immune infiltration.
ObjectiveTo assess postoperative analgesia and early rehabilitation of continuous incision infiltration with ropivacaine in open gastrectomy. MethodsFrom June 2011 to October 2014, 50 patients underwent open gastrectomy were divided into two groups:standard analgesic therapy group (Abbreviation:standard group, n=25) and continuous incision infiltration with ropivacaine group (Abbreviation:ropivacaine group, n=25). All the patients were also given patient controlled intravenous analgesia (PCIA). Points of visual analog scale (VAS), Bruggrmann comfort scale (BCS), and nausea and vomiting were assessed at different time during the first 48 hours postoperatively. Total sufentanil dosage, the first postoperative ambulation time, bowel recovery time, postoperative hospital stay, and incision infection rate were compared between two groups. ResultsAt 4 h, 8 h, 16 h, 24 h, 48 h postoperatively, the points of VAS in the ropivacaine group were significantly lower than those in the standard group (P < 0.05), the points of BCS in the ropivacaine group were significantly higher than those in the standard group (P < 0.05). Compared with the standard group, the dosage of sufentanil was significantly less (P < 0.05), the bowel recovery time, the first postoperative ambulation time, and the postoperative hospital stay were significantly shorter (P < 0.05), the point of nausea and vomiting was significantly lower (P < 0.05) at 48 h postoperatively in the ropivacaine group. There was no difference of the incision infection rate between the two groups (P > 0.05). ConclusionContinuous incision infiltration with ropivacaine is effective and safe to relief postoperative pain and accelerate patient's recovery after open gastrectomy.
ObjectiveTo evaluate the early effectiveness of local infiltration anesthesia (LIA) with compound betamethasone in total knee arthroplasty (TKA). MethodsThe clinical data of 102 patients with knee osteoarthritis who were treated by TKA and met the selection criteria between May 2022 and March 2023 were retrospectively analyzed. They were divided into control group and study group according to whether LIA preparation was added with compound betamethasone, with 51 cases in each group. There was no significant difference of baseline data, such as age, gender, body mass index, operative side, preoperative range of motion (ROM), Knee Society Score (KSS), white blood cell (WBC), and hematocrit between the two groups (P>0.05). The intraoperative total blood loss and hidden blood loss were recorded, and WBC was recorded on the 1st, 2nd, and 3rd days after operation. Pain was assessed by visual analogue scale (VAS) score on the 1st, 2nd, and 3rd days after operation and morphine intake milligrames equivalent within 48 hours after operation. Passive ROM, maximum extension and flexion angles of knee joint were measured on the 3rd day after operation; the early postoperative complications were recorded. ResultsThere was no significant difference in total blood loss and hidden blood loss between the two groups (P>0.05). The postoperative pain levels in both groups were relatively mild, and there was no significant difference in VAS scores in the first 3 days after operation and in morphine intake milligrams equivalent within 48 hours after operation between the two groups (P>0.05). The WBC in the first 3 days after operation was significantly improved in both groups (P<0.05). The WBC in the study group was significantly higher than that in the control group on the 1st and 2nd days after operation (P<0.05), but there was no significant difference between the two groups on the 3rd day after operation (P>0.05). On the 3rd day after operation, the maximum extension angle of knee joint in the study group was smaller than that in the control group, while the maximum flexion angle and passive ROM of knee joint in the study group were larger than those in the control group, and the differences were significant (P<0.05). There were 6 cases of fever and 17 cases of deep venous thrombosis in the control group, and 1 case and 14 cases in the study group, respectively. There was no poor wound healing and periprosthetic joint infection in the two groups, and there was no significant difference in the incidence of complications between the two groups (P>0.05). ConclusionThe application of compound betamethasone in LIA during TKA is a safe and optimal strategy to promote the early postoperative rehabilitation of patients.
Objective To explore the long-term effectiveness of arthroscopic partial repair in treatment of massive irreparable rotator cuff tears from both the radiological and clinical perspectives. Methods A retrospective analysis was conducted on the clinical data of 24 patients (25 sides) with massive irreparable rotator cuff tears who met the inclusion criteria between May 2006 and September 2014. Among them, there were 17 males (18 sides) and 7 females (7 sides) with an age range of 43-67 years (mean, 55.0 years). There were 23 cases of unilateral injury and 1 case of bilateral injuries. All patients were treated with the arthroscopic partial repair. The active range of motion of forward elevation and abduction, external rotation, and internal rotation, as well as the muscle strength for forward flexion and external rotation, were recorded before operation, at the first postoperative follow-up, and at last follow-up. The American Association of Shoulder and Elbow Surgeons (ASES) score, the University of California at Los Angeles (UCLA) shoulder scoring, and Constant score were used to evaluate shoulder joint function. And the visual analogue scale (VAS) score was used to evaluate shoulder joint pain. MRI examination was performed. The signal-to-noise quotient (SNQ) was measured above the anchor point near the footprint area (m area) and above the glenoid (g area) in the oblique coronal T2 fat suppression sequence. The atrophy of the supraspinatus muscle was evaluated using the tangent sign. The global fatty degeneration index (GFDI) was measured to assess fat infiltration in the supraspinatus muscle, infraspinatus muscle, teres minor muscle, upper and lower parts of the subscapularis muscle. The mean GFDI (GFDI-5) of 5 muscles was calculated. Results The incisions healed by first intention. All patients were followed up with the first follow-up time of 1.0-1.7 years (mean, 1.3 years) and the last follow-up time of 7-11 years (mean, 8.4 years). At last follow-up, the range of motion and muscle strength of forward elevation and abduction, ASES score, Constant score, UCLA score, and VAS score of the patients significantly improved when compared with those before operation (P<0.05). Compared with the first follow-up, except for a significant increase in ASES score (P<0.05), there was no significant difference in the other indicators (P>0.05). Compared with those before operation, the degree of supraspinatus muscle infiltration worsened at last follow-up (P<0.05), GFDI-5 increased significantly (P<0.05), and there was significant difference in the tangent sign (P<0.05); while there was no significant difference in the infiltration degree of infraspinatus muscle, teres minor muscle, and subscapularis muscle, upper and lower parts of the subscapularis muscle (P>0.05). Compared with the first follow-up, the SNQm and SNQg decreased significantly at last follow-up (P<0.05). At the first and last follow-up, there was no correlation between the SNQm and SNQg and the ASES score, Constant score, UCLA score, and VAS score of the shoulder (P>0.05). Conclusion Arthroscopic partial repair is effective in treating massive irreparable rotator cuff tear and significantly improves long-term shoulder joint function. For patients with severe preoperative fat infiltration involving a large number of tendons and poor quality of repairable tendons, it is suggested to consider other treatment methods.
ObjectiveTo explore the interaction between immune cell infiltration and extracellular matrix (ECM) in diffuse gastric cancer (DGC), and to identify novel diagnostic biomarkers and therapeutic targets. MethodsTranscriptomic data of DGC patients from The Cancer Genome Atlas (TCGA) database were analyzed to screen potential regulator factor of immune-related and ECM receptor-related signaling pathways. Differential expression of the identified regulator was assessed between the DGC tissues and the adjacent gastric tissues. Bioinformatics analysis was utilized to evaluate the relation between the regulator factor and immune cell infiltration and ECM, as well as prognosis. The clinical validation was performed using 90 paraffin-embedded DGC tissues and adjacent gastric tissues from the patients treated at The Lanzhou University Second Hospital (hereafter “our hospital”) from January 2017 to December 2019. The immunohistochemical staining was employed to examine the expression of regulator factor, followed by analysis of its association with immune cell infiltration, clinicopathologic features, and prognosis. Additionally, 10 paired DGC tissues and adjacent gastric tissues from the patients treated in our hospital in 2024 were collected for validation using real-time quantitative PCR to assess mRNA expression. The significance level was set at α=0.05. ResultsThe collagen type I alpha 1 chain (COL1A1), a potential regulator factor linked to immune and ECM receptor signaling pathways, was identified from the TCGA database. The COL1A1 was significantly overexpressed in the DGC tissues compared to the adjacent gastric tissues (P<0.001), and its high expression correlated with poorer prognosis [HR(95%CI)=2.98(1.21, 7.30), P=0.017]. The COL1A1 gene expression negatively correlated with CD8+ T cell enrichment score (CIBERSORT: r=−0.17, P<0.001; xCELL: r=−0.32, P<0.001) but positively correlated with M2 tumor-associated macrophage enrichment score (CIBERSORT: r=0.32, P<0.001; xCELL: r=0.24, P<0.001). The clinical validation confirmed that the COL1A1 protein and mRNA were both overexpressed in the DGC tissues (P<0.001). The patients with high COL1A1 protein expression had worse overall survival (P<0.001), and high expression (vs. low) was an independent risk factor for postoperative overall survival [HR(95%CI)=6.607(3.374, 12.940), P<0.001]. The COL1A1 protein expression positively correlated with CD163 (an M2 macrophage marker; r=0.76, P<0.001) and negatively with CD8+ (T cell marker, r=−0.84, P<0.001). ConclusionThis study demonstrates that COL1A1 is a potential therapeutic target for immune suppression and ECM interaction in DGC and a critical prognostic factor for long-term survival in patients with DGC.
Objective To investigate the effect of adductor canal block combined with local infiltration anesthesia on the rehabilitation of primary total knee arthroplasty (TKA). Methods A total of 104 patients who met the selection criteria for the first unilateral TKA between March 2017 and August 2017 were included in the study. They were randomly divided into trial group (53 cases) and control group (51 cases). In the trial group, the adductor canal block with intraoperative local infiltration anesthesia were performed. In the control group, only intraoperative local infil-tration anesthesia was performed. There was no significant difference in gender, age, body mass index, diagnosis, effected side, and the preoperative American Society of Anesthesiologists (ASA) grading between 2 groups (P>0.05). The operation time, length of stay, and complications were compared between 2 groups, as well as visual analogue scale (VAS) score of incision at rest and during activity, the range of motion (ROM) of knee flexion and extension activity, limb swelling (thigh circumference), walking distance, and pain VAS score while walking. Results The operation time of the trial group was significantly shorter than that of the control group (t=–2.861, P=0.005). However, there was no significant difference in length of stay between 2 groups (t=–0.975, P=0.332). The wound effusion occurred in 1 patient of trial group and 2 of control group; hematoma occurred in 2 patients of trial group and 3 of control group; no symptom of intermuscular venous thrombosis occurred in 1 patient in each of 2 groups; ecchymosis occurred in 14 patients of trial group and 15 of control group; there was no significant difference in the incidence of related complications between 2 groups (P>0.05). There was no significant difference in the preoperative VAS score at rest and during activity, ROM of knee flexion and extension activity, and thigh circumference between 2 groups (P>0.05). However, there were significant differences in the VAS score at rest and during activity after 2, 4, 8, and 12 hours, ROM of knee flexion and extension activity after 1 and 2 days, and the walking distance on the day of discharge, pain VAS scores while walking after 1 and 2 days and on the day of discharge, and thigh circumference after 1 day between 2 groups (P<0.05). Conclusion For the primary TKA, the adductor canal block combined with local infiltration anesthesia can early relieve the initial pain of the incision, shorten the operation time, and promote the mobility and functional recovery of the knee joint.
Objective To improve the diagnosis and treatment of pulmonary infiltration with eosinophilia (PIE). Methods Patients who were diagnosed with PIE in the First Affiliated Hospital of Guangzhou Medical University from January 2004 to December 2013 were recruited and retrospectively analyzed. Data of etiology, clinical manifestation, imaging and pathological features were recorded. Results pulmonary eosinophilic granuloma (PEG) (n=2), eosinophilic granulomatosis with polyangiitis (EGPA) (n=7), Löffler syndrome (n=4), allergic bronchopulmonary aspergillosis (ABPA) (n=16), and chronic eosinophilic pneumonia (CEP) (n=19). There were 27 males and 21 females. 47.9% of the PIE patients were diagnosed as asthma and treated with regular treatment but had not been controlled well. PEG was characterized with wheeze and anhelation in clinical manifestations, unelevated blood eosinophil counts and percentage, significant small airway abnormalities in lung function, diffuse pneumonectasis in Chest CT, and appearance of eosinophil cells in alveole. EGPA shows dyspnea and cough in clinical manifestations, as well as other organs function damaged, unelevated blood eosinophil counts and percentage, significant FEV1/FVC and small airway abnormalities in lung function, tree-in-bud in Chest CT, appearance of eosinophilic granuloma outside blood vessels. Löffler syndrome also showed cough, shorter course of disease, normal lung function and diffusion. ABPA showed wheeze and cough, 31.3% of them with hemoptysis, normal blood eosinophil count, central bronchiectasis in Chest CT. CEP also showed dyspnea and cough. 21.1% of CEP patientshad chest pain, increasing sputum eosinophil percentage compare with blood eosinophil percentage, and small airway abnormalities in lung function. Conclusions Most of PIE patients are diagnosed as asthma but haven’t gotten well controlled under the regular anti-asthmatic treatment. Patients with PIE have increasing eosinophil counts and decreasing lung function. The diagnosis of PIE still depends on clinical manifestation, laboratory test, imaging and pathological examination.
Tripartite motif 5 (TRIM5) plays a significant function in autophagy and involves in immune and tumor processes. While the function of TRIM5 remains poorly understood in glioma. We purpose to evaluate the possible prognostic role of TRIM5 in glioma via bioinformatics analyses. The database clinical samples of glioma in this study included low grade glioma (LGG) and glioblastoma multiforme (GBM). TRIM5 expression in glioma tissues were explored in Oncomine, GEPIA and The Cancer Genome Atlas (TCGA) databases. Survival analysis and the multivariate Cox regression analysis of TRIM5 based on TCGA were used to evaluate the prognostic role of TRIM5. The protein networks of TRIM5 was detected by STRING database. KEGG enrichment analyses were performed to predict the potential molecular pathways of TRIM5 in glioma. In addition, immune infiltration analysis was conducted by CIBERSORT and TIMER databases. We found that TRIM5 was strongly increased in glioma samples compared with normal samples in Oncomine, GEPIA and TCGA databases. Higher TRIM5 was significantly contributed to worse overall survival (OS) in LGG+GBM patients and LGG patients, while was no correlated with OS of GBM patients. Interaction networks analysis identified that IRF3, IRF7, OAS1, OAS2, OAS3, OASL, GBP1, PML, BTBD1 and BTBD2 proteins were contacted with TRIM5. Moreover, KEGG revealed that apoptosis and cancer- and immune-related pathways were enriched with elevated TRIM5. Specifically, TRIM5 could influence the immune infiltration levels, such as activated NK cells, monocytes, activated mast cells and macrophages in glioma. In conclusion, our data indicated that TRIM5 was upregulated in glioma tissues and associated with poor prognosis and immune infiltration. TRIM5 may be acted as a biomarker in prognosis and immunotherapy guidance of glioma.
