ABSTRACT

BACKGROUND@#Methylene blue is the most commonly used tracer for sentinel lymph node (SLN) biopsy (SLNB) in China. This study aimed to investigate the feasibility of clinical application of SLNB using methylene blue dye (MBD) for early breast cancer and the prognosis of patients with different SLN and non-SLN statuses.@*METHODS@#We retrospectively analyzed the clinicopathological data of patients with early breast cancer treated at the Peking University First Hospital between 2013 and 2018. We calculated the SLN identification rate (IR) in SLNB with MBD and the false-negative rate (FNR), and analyzed the prognosis of patients with different SLN and non-SLN statuses using Kaplan-Meier curves.@*RESULTS@#Between January 2013 and December 2018, 1603 patients with early breast cancer underwent SLNB with MBD. The SLN IR was 95.8% (1536/1603). Two SLNs (median) were detected per patient. There were significant differences in FNR between patients with SLN micrometastasis and macrometastasis (19.0% vs. 4.5%, χ2 = 12.771, P < 0.001). Chi-square test showed that there were significant differences in SLN successful detection rates among patients with different vascular tumor embolism status (96.3% vs. 90.8%, χ2 = 9.013, P = 0.003) and tumor (T) stages (96.6% vs. 94.1%, χ2 = 5.189, P = 0.023). Multivariate analysis showed that vascular tumor embolism was the only independent factor for SLN successful detection (odds ratio: 0.440, 95% confidence interval: 0.224-0.862, P = 0.017). Survival analysis showed a significant difference in disease-free survival (DFS) between patients with non-SLN metastasis and patients without non-SLN metastasis (P = 0.006).@*CONCLUSION@#Our single-center data show that, as a commonly used tracer in SLNB in China, MBD has an acceptable SLN IR and a low FNR in frozen sections. This finding is consistent with reports of dual tracer-guided SLNB. Positive SLNs with non-SLN metastasis are associated with DFS.

ABSTRACT

Anti-glutamic acid decarboxylase antibody-associated encephalitis is a kind of autoimmune encephalitis mediated by anti-glutamic acid decarboxylase antibody, which belongs to anti-neuronal intracellular synaptic protein antibody-associated encephalitis. Clinical manifestations include stiff-person syndrome, cerebellar ataxia, limbic encephalitis, seizures, etc., often associated with a variety of autoimmune diseases, rarely associated with tumors. Detection of anti-glutamic acid decarboxylase antibody is crucial for clinical diagnosis. Immunotherapy helps to relieve symptoms and improve prognosis. The incidence of this disease is low, and there are few reports at home and abroad. This paper intends to review the research on this encephalitis, hoping to improve the clinicians′ understanding and the level of diagnosis and treatment of the disease.

ABSTRACT

Objective:To detect the expression of inhibitor of DNA binding-2(ID-2) in colorectal adenocarcinoma and analyze its relationship with proliferation.Methods:A total of 67 patients with colorectal adenocarcinoma diagnosed in North China University of Science and Technology Affiliated Hospital were selected from November 2014 to September 2015, tumor tissue as the research objects.All patients underwent radical operation.The tumor tissue was taken as the observation group, and the normal colonic mucosa tissue>3 cm from the edge of the tumor was taken as the control group.Immunohistochemistry was used to detect the expression of ID-2 of the two groups and the Ki67 of cancer tissue.SW480 cell line of ID-2 overexpression was constructed.The expression of proliferating cell nuclear antigen(PCNA)was detected by Western Blot.Cell activity was detected by CCK-8 test.Correlation was analyzed between ID-2 and Ki67 by pearman correlation analysis.Prognostic value of ID-2 was analyzed by Kaplan-Meier survival analysis and Log-rank test in colorectal adenocarcinoma.Results:The positive rate of ID-2 was 49.3%(33/67) in the observation group, which was higher than 9.0%(6/67) in the control group, and the difference between the two groups was was statistically significant(χ 2=23.927, P<0.05). In the observation group, the expression of ID-2 was statistically significant in different invasion depth(serosa and extraserosa was 68.7%(22/32), serosa and extraserosa was 31.4%(11/35)), degree of differentiation(low differentiation was 80.0%(8/10), medium differentiation was 57.9%(11/19), high differentiation was 36.8%(14/38)), clinical stage(Ⅲ and Ⅳ stage were 64.3%(18/28), Ⅰ and Ⅱ stage were 38.5%(15/39)), lymph node metastasis(metastasis was 70.8%(17/24), no metastasis was 37.2%(16/43)) and tumor thrombus(yes was 75.0%(12/16), no was 41.2%(21/51)). The difference was statistically significant (χ 2 value were 6.311, 4.023, 4.349, 6.967 and 5.575, respectively, all P<0.05). Positive correlation was found between ID-2 and Ki67( r=0.65, P<0.05). Survival analysis showed that the expression of ID-2 was related to the prognosis of patients (X2=5.29, P=0.013). Compared with empty vector transfection group and blank control group, the expressions of PCNA and the activity ID-2 overexpression colon cancer cells increased( P<0.05). Conclusion:The higher expression of ID-2 is related to clinicopathological features and prognosis in colorectal adenocarcinoma.The abnormal expression of ID-2 may play a role in regulating the proliferation of colon adenocarcinoma.

ABSTRACT

BACKGROUND: Compared with traditional hemostatic methods, absorbable hemostatic materials are more expensive and have lower awareness, but they have greater advantages in certain surgical procedures. OBJECTIVE: To review the classification, clinical use, safety and development status of absorbable hemostatic materials. METHODS: The computer was used to search the PubMed database for relevant literature published from January 2003 to March 2020. The search terms were “Absorbable Hemostatic Agents; Fibrin adhesives; Hemorrhage; Hemostatic dressings; Hemostats; Mechanical hemostats; Sealants”. China National Knowledge Infrastructure was retrieved for relevant literature published from January 2004 to March 2020. The search terms were “absorbable hemostatic material; hemostatic material; clinical research”. RESULTS AND CONCLUSION: Absorbable hemostatic materials mainly produce hemostasis by accelerating the blood coagulation process of wounds. Common hemostatic products include cellulose, starch and other plant polysaccharides, gelatin/collagen, chitosan, and fibrinogen. Different materials have different hemostatic mechanisms. Oxidized regenerated cellulose, starch, gelatin/collagen and chitosan hemostatic materials mainly form platelets by providing platelet activation and aggregation. Fibrinogen hemostatic materials can be used in the coagulation cascade involved in the formation of fibrin clots. The use of absorbable hemostatic materials depends on the doctor’s experience or preference. Clinicians need to choose one or more hemostatic material combinations according to the actual situation of the patient.

ABSTRACT

Through collecting the literature data of the needling technique with filiform needle in 20 acupuncture-moxibustion teaching materials in the Republic of China, the manipulation techniques with filiform needle were analyzed, such as the technique of needle insertion, the technique of reinforcing and reducing, and the management of acupuncture abnormal conditions, as well as manual techniques and analgesics methods. It is found that the era of the Republic of China was the transition period of traditional acupuncture techniques to the modern ones in acupuncture-moxibustion teaching materials, in which, the twirling technique was predominated in the technique of needle insertion. In that period, the insertion technique of tube needle had been introduced and simplified, the theory and method of the new-style technique of reinforcing and reducing were emerged and the types of acupuncture abnormal conditions recorded in the teaching materials were different from those at present. Additionally, the applicable manipulation had not been specified nationally. There were the highly influential teaching materials, i.e. , and . The acupuncture-moxibustion teaching materials in the Republic of China has been influenced by the transition of acupuncture-moxibustion education modes, the introduction of Chinese-translation version of Japanese acupuncture-moxibustion books, the academic thoughts of acupuncture masters and the manufacturing process of needle devices.

ABSTRACT

Small cell lung cancer (SCLC), characterized by early metastasis, relapse, relapse and resistance and poor prognosis, still faces difficulties in treatment. Recently, Immunotherapy is a novel treatment for SCLC, researchers are also eager to achieve a breakthrough in targeted treatment of SCLC. Genomic instability of SCLC and sensitivity to cytotoxic chemotherapy, therefore, poly ADP-ribose polymerase (PARP) inhibitors targeting DNA repair related pathways have become a hotspot in the research of SCLC targeted therapy. Studies on PARP inhibitors in SCLC have been conducted in combination with other therapeutic strategies, including the treatment of recurrent SCLC and first-line treatment,as well as maintenance treatment after induction. These studies also explored the predictive markers of PARP inhibitors in SCLC. Although the current results of PARP inhibitors in SCLC are limited, and the predictive markers are also inconsistent, we also see that PARP inhibitors could be a breakthroughfor precision medicine of SCLC.

ABSTRACT

Objective@#To analyze the long-term trend of mortality and years of life lost (YLL) of gastric cancer in Tianjin from 1999 to 2015.@*Methods@#From January 1, 1999 to December 31, 2015, the data of gastric cancer deaths was collected from the Tianjin death surveillance system. The inclusion criteria of death due to gastric cancer were coded by using 151 in the 9th edition of the international classification of diseases (ICD) (1999-2002) and C16 in the 10th edition of ICD (2003-2015). The crude and age-standardized mortality rate (ASR) of gastric cancer was calculated according to Segi′s world standard population. YLL was calculated according to the standard method of the disease burden of WHO. The Joinpoint regression was used to calculate the average annual percentage change (AAPC) to indicate the trend of mortality and YLL of gastric cancer.@*Results@#From 1999 to 2015, there were 20 000 deaths of gastric cancer in Tianjin. The proportion of gastric cancer death in the population aged 0-44 years old, 45-64 years old, and 65 years old and above was 4.9%, 30.4%, and 64.8%, respectively. The proportion of males and urban was 67.1% and 67.5%, respectively. From 1999 to 2015, the crude mortality rate was from 12.10/100 000 to 12.58/100 000. The ASR was from 11.04/100 000 to 7.24/100 000. The average annual YLL number was 29 625.83 person-years and the rate was 3.09 person-years per thousand people. From 1999 to 2015, the crude mortality rate and the PYLL of gastric cancer in Tianjin were stable (the AAPC was 0.34% and -0.24%, all P values >0.05). The ASR showed a downward trend (AAPC=-2.58%, P<0.001).@*Conclusion@#From 1999 to 2015, the ASR of gastric cancer in Tianjin showed a downward trend, and the YLL of gastric cancer was stable.

ABSTRACT

Objective::To study the correlation between endogenous hormone content, related enzyme activity and embryogenesis during the stratification of Acanthopanax senticosus seeds, and to provide theoretical basis for application of endogenous hormones and related physiological indicators in regulating germination of A. senticosus seeds in production and scientific research. Method::Endophytic fungi as well as different concentrations of nitric oxide and hydrogen peroxide solution were used for soaking the seeds of A. senticosus, and then thermophilic stratification was conducted for the seeds. The content of endogenous hormones such as gibberellin (GA3), abscisic acid (ABA), indole acetic acid (IAA), indole butyric acid (IBA) and salicylic acid (SA) in seeds of A. senticosus were tested by high performance liquid chromatography (HPLC), and the activity change of enzymes in vivo such as catalase (CAT), superoxide dismutase (SOD), peroxidase (POD), and malondialdehyde (MDA) were tested. The correlation between the embryo rate and the hormones and their enzyme activities in the seeds of A. senticosus was studied by the grey correlation method. Result::The embryo rate was significantly positively correlated with IAA, GA3, and CAT, with correlation coefficient of 1.086, 0.935 and 1.067, respectively. There was a significant positive correlation between IAA, GA3, CAT, IBA, and SA, but with a significant negative correlation with ABA, MDA, and POD. The correlation degree was as follows: IAA>CAT>GA3>IBA>SA>SOD>ABA>POD>MDA. Conclusion::IAA, GA3 and CAT have significant promoting effects on embryo rate, and there is a significant correlation between hormone content and enzyme activity, which provides a basis for exploring the seed germination mechanism of A. senticosus.

ABSTRACT

ObjectiveTo investigate the expression of the long non-coding RNA (lncRNA) EXOC7 in serum and liver biopsy tissue of patients with nonalcoholic fatty liver (NAFLD) and its clinical significance. MethodsA total of 120 patients who underwent liver biopsy in The Affiliated Hospital of Southwest Medical University from January 1, 2013 to December 31, 2018 and were diagnosed with NAFLD based on imaging and histopathology were enrolled, among whom 47 had nonalcoholic fatty liver (NAFL) and 73 had nonalcoholic steatohepatitis (NASH). A total of 50 liver disease patients without steatosis or steatohepatitis were enrolled as control group. Real-time PCR was used to measure the expression of lncRNA EXOC7 in liver tissue and serum. The t-test was used for comparison of continuous data between two groups; an analysis of variance was used for comparison between multiple groups, and the SNK-q test was used for further comparison between two groups. A chi-square test was used for comparison of categorical data between groups. A Pearson correlation analysis was used to investigate the correlation between lncRNA EXOC7 and biochemical parameters. The receiver operating characteristic (ROC) curve was plotted to investigate the diagnostic value of lncRNA EXOC7. ResultsCompared with the control group, the patients with NAFL or NASH had significant increases in the expression of lncRNA EXOC7 in liver tissue and serum (all P<0.05), and the level of such expression increased with the aggravation of hepatic steatosis and inflammation (F=19.96, P<0.05). The correlation analysis showed that the expression of lncRNA EXOC7 was positively correlated with total triglyceride and low-density lipoprotein cholesterol (r=0.785 and r=0.847, both P<0.001) and was negatively correlated with high-density lipoprotein cholesterol and insulin sensitivity index (r=-0.726 and -0.709, both P<0.001). LncRNA EXOC7 had an area under the ROC curve of 0.812 (95% confidence interval: 0.599-0.915, P<0001), a sensitivity of 8542%, and a specificity of 81.17% in the diagnosis of NAFLD. ConclusionLncRNA EXOC7 is highly expressed in patients with NAFLD, and the expression of lncRNA EXOC7 increases with the aggravation of hepatic steatosis and inflammation, suggesting that lncRNA EXOC7 may be a potential new target for the prevention and treatment of NAFLD.

ABSTRACT

Ovarian cancer is one of the most serious gynecological tumors in the world, and its mortality ranks first in gynecological malignancies. The study found that metformin is not only used as a first-line oral hypoglycemic agent for the treatment of type 2 diabetes, but also has a certain inhibitory effect on the occurrence and development of ovarian cancer. In recent years, domestic and foreign scholars have carried out experimental and epidemiological studies on the relationship between metformin and ovarian cancer. This review included 7 cohorts and 2 case-control studies on the incidence and prognosis of metformin and ovarian cancer. The results suggest that the use of metformin may improve the prognosis of ovarian cancer, however, due to the limited epidemiological studies of the disease, its relationship with ovarian cancer still needs further exploration.

ABSTRACT

Objective@#To investigate the mortality of colorectal cancer and its trend from 1999 to 2015 in Tianjin, China, and to explore the mortality features in different populations in order to provide data for prevention and control strategies of colorectal cancer.@*Methods@#Colorectal cancer mortality data between 1999 and 2015 were collected from Tianjin population - based mortality surveillance system maintained by the Tianjin Centers for Disease Control and Prevention (CDC). Population data of permanent residents were collected from Tianjin Municipal Public Security Bureau. The number of new cases and deaths, incidence [including crude incidence, age-adjusted standardized incidence and 95% confidence interval (95% CI)], and mortality (including crude mortality, age-adjusted standardized mortality and 95% CI) of colorectal cancer were calculated. Standardized incidence and mortality of colorectal cancer were calculated using the Segi′s world standard population, adjusted with age and gender. JoinPoint regression and Cochran-Armitage trend test were used to determine the statistical significance of differences in mortality trend.@*Results@#A total of 31 376 new onset cases and 14 893 death cases of colorectal cancer were observed in Tianjin from 1999 to 2015. Colorectal cancer incidence increased from 1999 to 2015 with a standardized rate from 9.66/100 000 to 15.36/100 000 [annual percent change(APC)=3.48%, Z=23.21, P<0.001]. Colorectal cancer mortality increased from 1999 to 2015 with a standardized rate from 5.18/100 000 to 6.11/100 000 (APC=1.24%, Z=5.69, P<0.001). Both showed an increasing trend. The death proportion of colon cancer increased (39.67% in 1999 and 50.33% in 2015), while the death proportion of rectal caner decreased (60.33% in 1999 and 48.57% in 2015). The median age of colorectal cancer onset fluctuated steadily around 66 years old (APC=0.16, T=1.75, P=0.100); the median age of death increased from 69 to 73 years old (APC=0.43, T=8.81, P<0.001). From 1999 to 2015, the mortality of colorectal cancer showed a downward trend (all P<0.05) in the age groups of <35 and 35-44 years, while an upward trend (all P<0.05) in the age groups of 45-54 years, 55-64 years and ≥ 65 years. Colorectal cancer mortality in males increased with a standardized rate of 5.53/100 000 in 1999 to 7.33/100 000 in 2015(APC=2.29%, Z=7.86, P<0.001), while colorectal cancer mortality in females flatted with a standardized rate of 4.83/100 000 in 1999 to 4.89/100 000 in 2015 (APC=0.10%, Z=-0.30, P=0.752). Colorectal cancer mortality increased with a standardized rate of 6.75/100 000 in 1999 to 7.33/100 000 in 2015 (APC=0.54%, Z=1.98, P=0.048) in urban areas and of 3.18/100 000 in 1999 to 4.38/100 000 in 2015 (APC=2.47, Z=6.46, P<0.001) in rural areas, whose differences were significant. Standardized mortality rate in rural area was lower but the rising velocity was faster as compared to urban area.@*Conclusions@#Crude mortality and standardized mortality of colorectal cancer increase from 1999 to 2015 in Tianjin population. The people of elder, male and urban area have higher mortality. The mortality in people of male and rural area presents a faster rising state. Further efforts to reduce colorectal cancer mortality in Tianjin are needed to prevention and control of colorectal cancer.
