ObjectiveTo evaluate the impact of local infiltration analgesia on postoperative pain after hip arthroplasty. MethodsRelevant randomized controlled trials comparing the analgesia effect and adverse effects between local infiltration analgesia group and non-local infiltration analgesia group (control group) were identified from Cochrane Library, Embase, PubMed, China National Knowledge Infrastructure, VIP database and Wanfang database from their establishment until May 2016. A systematic review was performed to compare the pain scores and adverse events between those two groups. Effective data were pooled for Meta-analysis with software RevMan 5.2.0. ResultsTwelve eligible trials were identified in this study. The pain scores of the two groups of patients during rest time after surgery were significantly different[WMD=-19.06, 95%CI (-21.51, -16.62), P<0.000 01]; the pain scores were also significantly different during activity time[WMD=-11.45, 95%CI (-15.56, -7.34), P<0.000 01]. There was significant difference in postoperative nausea and vomiting between the two groups[RR=0.59, 95%CI (0.42, 0.84), P=0.003]. The pain degree and incidence of nausea and vomiting in the local infiltration analgesia group were lower than the control group, but there was no significant difference between the two groups in terms of urinary retention, itch and hypotension (P>0.05). ConclusionLocal infiltration analgesia is effective in reducing postoperative pain without any additional adverse reactions.
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.
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 systematically evaluate the analgesic efficacy of local infiltration analgesia versus femoral nerve block for total knee arthroplasty. MethodsDatabases including PubMed, EMbase, The Cochrane Library (Issue 4, 2016), WanFang Data, CBM, and CNKI were searched to collect randomized controlled trials (RCTs) about the analgesic efficacy of local infiltration analgesia versus femoral nerve block for total knee arthroplasty from inception to April 2016. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. The meta-analysis was conducted using RevMan 5.3 software. ResultsA total of 13 RCTs involving 1 001 patients were included. The results of meta-analysis showed that: There were no significant differences in pain scores at rest (SMD=0.02, 95%CI -0.23 to 0.27, P=0.86), morphine consumption on movement (MD=-1.85, 95%CI -4.67 to 0.97, P=0.20), incidence of post-operative nausea and vomiting (RD=0.02, 95%CI -0.03 to 0.08, P=0.41) and incidence of post-operative knee infection (RD=0.01, 95%CI -0.02 to 0.03, P=0.60) between the two groups, but he local infiltration analgesia group had lower length of stay than the femoral nerve block group with statistical difference (SMD=-0.24, 95%CI -0.41 to -0.07, P=0.005). ConclusionLocal infiltration analgesia provides similar postoperative analgesia after total knee arthroplasty to femoral nerve block. However, due to the limited quantity of the included studies, the above conclusion still need to be verified by more high quality studies.
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.
Objectives To overview the systematic reviews/meta-analyses of safety of femoral nerve block (FNB) used as a postoperative analgesic technique in patients undergoing total knee arthroplasty (TKA). Methods We searched databases including The Cochrane Library, PubMed, EMbase, CNKI, WanFang Data, and VIP from inception to July, 2016. Two reviewers independently screened literature, extracted data and used AMSTAR to evaluate the methodological quality of the included studies. The major indexes used to evaluate the safety of FNB were the incidence rates of symptoms including nausea, vomiting, sedation, retention of urine, dizziness, pruritus, hypotension, falls, nenous thromboembolism and deep infection. Results A total of 12 systematic reviews/meta-analyses were included.They assessed the safety of FNB compared with local infiltration analgesia (LIA), periarticular multimodal drug injection (PMDI), epidural analgesia (EA), patient-controlled intravenous analgesia of opioids (PCA) and adductor canal block (ACB), respectively. The methodological quality of included studies were medium, with the scores between 3 to 10. The results of overview indicated that: FNB had lower incidence rates of nausea and vomiting compared with EA and PCA, but had higher than ACB. FNB had lower incidence rates of sedation and retention of urine compared with EA and PCA. FNB had lower incidence rates of dizziness compared with EA and PCA, and lower incidence rate of hypotension compared with EA. Conclusion Current evidence suggests that FNB is safer than EA and PCA. Due to the limited quantity and quality of the included studies, the above conclusions are needed to be verified by more high-quality studies.
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.
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.
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.
Objective To investigate the relationship between the expression of mast cell expressed membrane protein 1 (MCEMP1) in gastric cancer and its relationship with prognosis and tumor immune infiltration. Methods Transcriptome expression profile data and clinical data information of gastric cancer and normal samples were downloaded from TCGA database, and differentially expressed genes in gastric cancer tumor microenvironment were extracted using R 4.0.5 software. Protein-protein interaction network of differentially expressed genes was constructed by using STRING online website, protein-protein interaction network and univariate Cox proportional hazards regression analysis were used for cross-tabulation analysis to obtain key genes. Kruskal-Wallis rank sum test was used to investigate the correlation between key genes and clinicopathological features. The possible signaling pathways involved in key genes were predicted by gene set enrichment analysis. We further analyzed the relationship between expression of key gene and the level of immune infiltration and immune molecules in gastric cancer by TISIDB online database and CIBERSORT algorithm. Results A total of 760 differentially expressed genes in gastric cancer were found and a key gene of MCEMP1 was derived from cross-tabulation analysis based on the results of protein-protein interaction network and univariate Cox proportional hazards regression analysis. Expression of MCEMP1 was significantly upregulated in gastric cancer tissues (P<0.001), and survival analysis showed that the overall survival rate of the group with high expression level of MCEMP1 was lower than that of low expression [HR=1.176, 95%CI (1.066, 1.297）, P=0.046]. Expression of MCEMP1 also correlated with age, T-stage, and clinical stage of gastric cancer (P<0.05) , and expression of MCEMP1 was significantly associated with a variety kinds of immune cells and expression of immune molecules (P<0.05). Conclusion MCEMP1 is a potential prognostic marker for gastric cancer and is associated with immune infiltration in gastric cancer.
