Lung cancer is the most common cancer worldwide. The outcome and management of lung cancer patients could be improved by early diagnosis and prognosis. MicroRNAs (miRNAs) have been implicated in signaling pathways regulating a variety of biological processes and play important roles in the development of carcinoma. Moreover, miRNAs can exist in the circulation in a remarkably stable form. All of these suggest miRNAs as new potentially clinical biomarkers for diagnosis and prognosis of lung cancer. In this review, we aim to discuss diagnostic and prognostic value and potential clinical utility of miRNAs in serum.
Objective To study the advances in the relationship between the number of infiltrating dendritic cells and the postoperative prognosis of digestive malignant tumor. MethodsThe literature in recent years on the relationship between the number of infiltrating dendritic cells and the postoperative prognosis of digestive malignant tumor was reviewed.ResultsThe number of infiltrating dendritic cells among esophageal cancer,and gastric carcinoma,colonic cancer and pancreatic cancer was associated with a better prognosis.Conclusion The population density of dendritic cells among the malignant tissue could be regarded as an independent indicator in estimating the postoperative prognosis of malignant tumor.
ObjectiveTo explore the clinicopathological characteristics of combined hepatocellular and cholangiocarcinoma (cHCC-CC), and the prognostic factors associated with survival. MethodesThe clinical features of 31 patients with cHCC-CC from 1995 to 2010 in West China Hospital of Sichuan University underwent liver resection were analyzed retrospectively. The prognostic factors were analyzed by using univariate and multivariate analysis. ResultsOf these 31 patients, 25 men and 6 women, with a median age of 58 years, underwent liver resection for cHCC-CC. Twentythree cases (74.2%) showed positive of hepatitis B surface antigen (HBsAg), 13 cases (41.9%) had elevated AFP≥20μg/L, 18 cases (58.1%) with liver cirrhosis, 8 cases (25.8%) showed presence of lymph node metastases. The 1-, 3-, and 5-year overall survival rates of these patients were 61.3%, 32.3%, and 12.9%, respectively. Univariate analysis showed that invasion of portal vein, microscopic tumor thrombi, positive resection margins, and lymph node involvement were significant prognostic factors. Multiple analysis revealed the positive resection margins and lymph node involvement were independent prognostic factors for overall survival. ConclusionsThe prognosis of patients with cHCC-CC is poor. R0 resection is the only available treatment in curing these patients.
ObjectiveTo analyze the epidemiological characteristics and injury patterns of eye trauma in children and adolescents in China. MethodsA multicenter cross-sectional, retrospective, observational study. Based on the Chinese Eye Trauma Registry database, 189 patients (189 eyes) aged 0-18 years (13.4%, 189/1 412) of 1 412 patients (1 435 eyes) with eye trauma who were hospitalized from January to December 2023 were included in the study. Patients were recruited from 23 tertiary general hospitals or ophthalmology specialty hospitals located in 17 provincial-level administrative regions across six major geographical areas in China (North China, East China, South China, Central China, Northwest China, and Southwest China). The analysis focused on population characteristics, epidemiological features, injury patterns, and visual outcomes of children from different geographical regions and age groups. Among the 189 eyes, 95 eyes underwent secondary surgery. A total of 23 eyes were excluded due to non-cooperation during examination, no light perception, or only light perception. Ultimately, 72 eyes were included in the statistical analysis. Of these, 36 eyes had follow-up data and were used to observe postoperative visual outcomes. ResultsAmong 189 patients, 143 were males (75.7%, 143/189) and 46 were females (24.3%, 46/189). Age 8.73 (1-18) years old. The gender composition of all age groups was mainly male. The geographical distribution showed that East China had the largest number of cases, 55 (29.1%, 55/189). There were 70 cases (37.0%, 70/189) in 7-10 years old. The type analysis of eye trauma showed that in 189 eyes, mechanical ocular trauma accounted for 130 eyes, of which 105 (80.8%, 105/130) eyes had open globe injuries and 25 (19.2%, 25/130) eyes had closed globe injuries. 122 eyes received emergency surgery within 24 h after injury (accounts for 83.6% of emergency surgical cases, 122/146). In 36 eyes with complete follow-up data, the initial visual acuity distribution was: blind 23 eyes (63.9%), low visual acuity 6 eyes (16.7%), visual acuity ≥0.3 in 7 eyes (19.4%). At the last follow-up, visual acuity improved in 12 eyes (33.3%) with blindness, 8 eyes (22.2%) with low visual acuity, and 16 eyes (44.4%) with visual acuity ≥0.3. The final visual outcome showed that the disability rate was 22.2% (8/36) and the blindness rate was 33.3% (12/36). ConclusionsChildren and adolescents account for 13.4% of the hospitalized patients with eye trauma in the same period, and there is a significant gender difference (male accounted for 75.7%). There are obvious age-specific distribution rules in the causes, locations and clinical features of eye trauma in children and adolescents of different ages.
Objective To explore the clinical significance of internal mammary nodes in diagnosis and treatment of breast cancer. Methods The research papers on internal mammary nodes at home and abroad were analyzed in order to summarize the distribution, metastasis, detection and the effects of clinical treatment of the internal mammary nodes in breast cancer. Results The internal mammary nodes mainly locate near the sternum, along with the internal mammary artery and vein in the thorax. They were prone to metastasize at early stage and the metastasis rate also increased with the increased number of axillary lymph nodes in breast cancer. It could influence the recovery of the breast cancer patients by taking biopsy and treatment to the internal mammary nodes. Conclusion The biopsy and treatment of internal mammary nodes are useful for the patients with breast cancer to avoid the recurrence and helpful to stage, treatment and prognosis judgement of the breast cancer patients.
ObjectiveTo analyze the clinical features and prognosis factors of aquaporin 4 (AQP4) antibody-positive neuromyelitis optica spectrum disorders related optic neuritis (NMOSD-ON). MethodsAn ambidirectional cohort study. From June 1, 2015 to June 1, 2019, 103 patients with AQP4 antibody-positive NMOSD-ON in Department of Neuro-ophthalmology, The First Medical Center of PLA General Hospital were included. All patients of followed-up period were ≥24 months. According to the best corrected visual acuity (BCVA) at the last follow-up, the affected eyes were divided into the low vision group [log of minimum resolution angle (logMAR) BCVA≥1.0] and the non-low vision group (logMAR BCVA＜1.0), 66 and 37 cases, respectively. The two groups of patients were compared the genernal clinical characteristics, and the logistic regression model and COX proportional hazard model were used to analyze the relevant factors affecting the patient's visual prognosis and recurrence. ResultsAmong the 103 cases, 96 cases (93.2%, 96/103) were female; 94 cases (91.3%, 94/103) had unilateral disease; 48 cases (46.6%, 48/103) were the first onset; 85 cases (82.5%, 85/103) were effected by eye pain or orbital pain; 21 cases (20.4%, 21/103) had optic disc edema; 51 cases (49.5%, 51/103) serologically autoimmune antibody test were positive. Orbital magnetic resonance imaging (MRI) was performed in 101 cases. There was no obvious abnormal signal in visual pathways except for 5 cases (5.0%, 5/101); 96 cases (95.0%, 96/101) had abnormal signal in the visual path, and the optic nerve was found in the orbit; 52 cases had abnormal optic nerve in orbital segment (51.5%, 52/101); 37 cases (35.9%, 37/103) recurred within 24 months. The recovery of logMAR BCVA after the first onset and the logMAR BCVA at the first onset, at 6 months of follow-up in two groups were 1.4±1.0, 0.3±0.4, 1.9±0.7 and 0.4±0.5, 2.1±0.6, 0.3±0.4, respectively; and there were statistically significant differences between the two groups of patients at different times（Z=－4.967,－7.603,－8.027; P＜0.001). Logistic regression multivariate analysis showed that recovery of BCVA≥1.0 logMAR after the first onset [odds ratio (OR)=226.276, P＜0.001] and the number of attacks (OR=8.554, P=0.003) were independent risk factors for low vision. Multivariate analysis of the Cox proportional hazards model showed the higher the MRI score [hazard ratio (HR)=0.588, P=0.007] and plasma exchange (HR=0.124, P=0.049) in the acute phase were protective factors for recurrence. ConclusionsVision loss accompanied by eye pain or orbital pain is the main symptom of onset AQP4 antibody-positive NMOSD-ON, a small number of patients have disc edema, 49.5% patients serologically autoimmune antibody test are positive. Abnormal optic nerve signals can be seen in 95.0% of patients in orbital MRI, and 51.5% patients have abnormalities in the orbital optic nerve. The worse the recovery of BCVA after the first onset and the greater the number of attacks are unfavorable factors affecting the prognosis of vision. High MRI scores and plasma exchange in the acute phase are favorable factors to prevent the recurrence of the disease.
ObjectiveTo introduce the general situation about oval cells and the advance in research on relation between the hepatic oval cells and hepatocellular carcinoma (HCC). MethodRelevant literatures in recent years about oval cells in hepatocellular carcinoma were collected and analyzed. ResultsHepatic oval cells are progenies of the hepatic stem cells that are thought to reside in the terminal branches of the biliary tree, termed the canals of Hering.After severe liver injury resulting in hepatocyte and cholangiocyte necrosis/apoptosis, the dual-potential oval cells will proliferate and differentiate into hepatocytes or cholangiocytes to replace the respective lost cell types.Recent studies have found many new oval cell surface markers, and promoted the recognition of oval cells.The level of oval cells proliferation is positively correlated with the malignant and inflammatory level of chronic liver diseases.More importantly, oval cells is involved in the occurrence, development, recurrence, and metastasis of liver cancer, and closely related to the prognosis of HCC. ConclusionAn improved understanding of the biological behavior of hepatic oval cells may lead to the development of novel diagnosis, treatment regimens, and prevention for hepatocellular carcinoma.
Objective To study the advances in research of breast cancer during pregnancy. Methods The literatures in recent years were reviewed. Results A lot of evidences suggested that the diagnosis may be delayed easily. The diagnosis was primarily made by needle aspiration cytology and biopsy. The treatment of pregnant breast cancer was not different from ordinary breast cancer, however the factor of foetus should be taken into account. Termination of pregnancy did not improve survival. Conclusion Pregnant breast cancer is mostly at later stage at the time of diagnosis and has poorer prognosis than ordinary breast cancer. The patients with breast cancer during pregnancy usually have an equivalent survival rate when compared with age and stagematched ordinary group. Future pregnancy may be allowed after two years of treatment in patients with early breast cancer.
Objective To summarize the clinical features, predisposing factors, diagnosis, therapeutic outcome, and prognosis of invasive pulmonary fungal infection( IPFI) . Methods 90 cases with pathologically proved IPFI, admitted in non-intensive care unit in Xiangya Hospital from January 2005 to February 2012, were retrospectively analyzed. Results The pathogenic examination revealed Aspergillosis in 56 cases( 62. 2% ) , Cryptococcus in 18 cases( 20. 0% ) , Mucormycosis in 6 cases( 6. 7% ) , and Histoplasma in 6 cases( 6. 7% ) , etc. The underlying diseases were reported in 87 cases, and mainly included COPD, pulmonary tuberculosis, and diabetes mellitus. Cough and expectoration were the common clinical symptoms. 49 patients ( 54. 4% ) received long-term and broad-spectrum antibiotic therapy. The CT results revealed masses type in 25 cases( 27. 8%) , nodule lesions type in 15 cases( 16. 7% ) , lung consolidation type in 22 cases( 24. 4% ) , cavity type in 22 cases( 24. 4% ) , aspergilloma type in 6 cases( 6. 7% ) . 47 patients were clinical diagnosed with IPFI before biopsy with preliminary diagnosis accordance rate of 52. 2% . 31 cases ( 34. 4% ) underwent surgical resection of pulmonary lesions, and no recurrence was detected over two-year follow up. 56 cases ( 62. 2% ) received systemic anti-fugal therapy, and 43 cases( 76. 8% ) were cured or significantly improved. 3 cases ( 3. 3% ) refused any therapy. Conclusions The most frequently isolated pathogen of IPFI is Aspergillosis. The mainly underlying diseases are COPD, pulmonary tuberculosis, and diabetes mellitus. Long-termand broad-spectrum antibiotic therapy may be the major risk factor. Pathological examination is needed for final diagnosis. Surgical procedure can achieve optimal prognosis.
ObjectiveTo investigate the prognostic value of platelet volume indices ［mean platelet volume (MPV) and platelet distribution width (PDW)］ in early period for patients with sepsis .MethodsThis retrospective study was conducted in a general ICU at a University Hospital from January 2015 to January 2017. Patients with sepsis were divided into a survival group and a death group according to 28-day prognosis. The demographic and clinical data were recorded and analyzed, including platelet indices, Charlson comorbidity index, Glasgow Coma Scale (GCS) score and Acute Physiology and Chronic Health Evaluation Ⅱ (APACHEⅡ) score. Multivariable COX proportional hazard ratio model was used to evaluate the 28-day mortality risk, and receiver operating characteristic (ROC) curve were used to evaluate the value of platelet volume indices.ResultsA total of 209 patients were enrolled in this study. Mean arterial pressure, pH, platelet count, serum creatinine, bilirubin, troponin I, prothrombin time, GCS score and platelet volume indices showed significant differences between the survival group (n=137) and the death group (n=72) (all P<0.05). Multivariable COX regression analysis revealed that the PDW was independently associated with 28-day mortality in sepsis (HR=1.068, 95%CI 1.002-1.139, P=0.043). The area under the ROC curve of PDW was 0.762 (95%CI 0.694 - 0.831), with a sensitivity of 86% and a specificity of 63% at a cut-off value of 18.65%.ConclusionPDW can be used as a powerful prognostic indicator in patients with sepsis following 28-day.
