Abstract: Objective　To analyze the epidemic characteristics of etiologically positive pulmonary tuberculosis, and the outcome of treatment in Liaoning Province from 2016 to 2022, aiming to provide a scientific basis for the formulation of tuberculosis prevention and control measures in Liaoning Province. Methods　The medical records information of registered pulmonary tuberculosis patients in Liaoning Province from 2016 to 2022 was collected from the "Tuberculosis Information Management System", a subsystem of the "China Disease Prevention and Control Information System". A descriptive analysis was performed on the epidemiological characteristics and treatment outcomes of cases of pathogen-positive pulmonary tuberculosis. Results　From 2016 to 2022, a total of 152 778 cases of active pulmonary tuberculosis were registered in Liaoning Province. Registration rates decreased from 54.48/100 000 in 2016 to 39.12/100 000 in 2022, displaying a downward trend (χ2trend=1 921.17, P<0.001). The etiological positive rate increased from 26.70% in 2016 to 51.21% in 2022, indicating an upward trend (χ2trend=5 203.00, P<0.001). The etiological positive registration rate increased from 14.54/100 000 in 2016 to 20.03/100 000 in 2022, showing an upward trend (χ2trend=647.97, P<0.001). The male-female ratio of etiological positive was 3.35∶1. The age group of 55-<65 had the highest incidence rate at 25.45% (16 127/63 376) among pathogen-positive pulmonary tuberculosis cases. Patients over 45 years of age accounted for 71.27% (41 570/63 376) of total cases, pointing towards an aging trend. The main occupations of the patients were household and unemployed, making up 41.78% (26 477/63 376) of total cases and showed an increasing year-on-year trend (χ2trend=17.404, P<0.001). Direct medical consultation was the primary mode of patient source at 50.28%(31 864/63 376), while 64.54%(40 904/63 376) cases reported a delay in seeking treatment. Seasonality was observed in the occurrence of pathogen-positive pulmonary tuberculosis, with February and September being the months of lowest incidence, while May and June witnessed peak incidences. The etiological positive patients were mainly in Shenyang, Dalian, Jinzhou and other regions. The proportion of successful treatment of etiologically positive decreased from 91.15% in 2016 to 85.88% in 2022, manifesting a downward trend (χ2trend=35.892, P<0.001). Conclusions　From 2016 to 2022, the incidence and registration rates of pathogen-positive pulmonary tuberculosis in Liaoning Province displayed an upward trend. Several characteristics were observed including seasonal variations, delayed treatment, regional distribution differences, and a decline in successful treatment rates. Targeted prevention and control measures should be formulated according to the actual situation in Liaoning Province.

Abstract: Objective To evaluate the application of TB laboratory detection technology in Liaoning Province from 2016 to 2022, and to provide scientific basis for further improving the detection rate of Mycobacterium tuberculosis in the province. Methods The medical records of registered tuberculosis patients in Liaoning Province from 2016 to 2022 were collected from the "Tuberculosis Information Management System" in the "China Disease Prevention and Control Information System" subsystem. Statistical analysis was performed for sputum coating, sputum culture, and molecular biology testing. Results From 2016 to 2022, a total of 152 778 patients with pulmonary tuberculosis were registered in Liaoning Province. The detection rate of sputum smear microscopy was 98.03% (149 775/152 778), the detection rate of sputum culture was 20.72% (31 661/152 778), and the detection rate of molecular biology testing was 20.21% (30 737/152 778). From 2018 to 2022, the rate of molecular biological detection showed an increasing trend (χ2trend=7 104.466, P<0.01), while from 2016 to 2021, the detection rate of sputum culture showed an increasing trend, with statistical significance (χ2trend=3,068.701, P<0.01). The sputum smear detection rate showed a downward trend（χ2trend=689.913, P<0.01). . There were significant differences in the results of sputum smear microscopy, sputum culture, and molecular biology testing, as confirmed by the McNemar test (P<0.01). The positive rate of pathogenic academics increased from 26.27% in 2016 to 51.55% in 2022, showing a yearly upward trend (χ2trend=5 262.863, P<0.01), with significant differences between each year (χ2=5 686.935, P<0.01). Among pulmonary tuberculosis patients with positive pathogenic microorganisms, the proportion of sputum smear-positive cases decreased from 94.32% to 52.36%, showing a downward trend (χ2trend=5 010.104, P<0.01). The proportion of culture-positive cases increased from 5.68% in 2016 to 12.83% in 2022, showing an upward trend (χ2trend=122.501, P<0.01). In Liaoning Province, molecular biology testing has been carried out since 2018, and the proportion of molecular biology-positive cases increased from 11.51% to 34.81%, showing an increasing trend (χ2trend=1 969.326, P<0.01). The number of positive patients in molecular biological tests in municipal hospitals accounted for 18.69% (8 386/44 778) of etiological positive patients, while the number of positive patients in county-level hospitals accounted for 13.61% (2 439/17 924) of etiological positive patients, with significant differences (χ2=231.594, P<0.01). Conclusions The implementation of molecular biology testing for tuberculosis in Liaoning Province is one of the main measures to improve the positive rate of etiology, and it helps to diagnose tuberculosis patients timely and accurately

Objective To detect the effect of cell density off both integrin αγβ6 expression and matrix metalloproteinase-9(MMP-9)secretion in colon cancer cells. Methods Flow cytometry was applied to analyze αγβ6 expression in human WiDr colon cancer cell lines and human HaCaT keratinocyte cells, respectively,at high-and low-cell density culture.The MMP-9 aetivity level for various coloIl cancer cell lines, WiDr and SW480 cells at high-and low-cell density culture was analyzed using Biotrak MMP-9 activity assay and Gelatin Zymography assay, respectively. Results High cell density significantly enhances integrin αγβ6 expression for WiDr cells expressing αγβ6 compared with low density,but no increase was observed for human keratinocyte HaCaT cells. Biotrak MMP-9 assay indicated that the amount of MMP-9 secreted per cell for WiDr and SW480 B6 cells at high cell density culture was(3.3±1.2)×10-7ng/cell and(27.2±3.0)× 10-7ng/cell respectively; However,at low cell density it was(1.8±0.7)× 10-7ng/cell and(10.9±2.0)×10-7 ng/cell,respectively. It was 2-3-fold higher for WiDr and SW480 β6 cells at high cell density compared with that at low cell density, but no density-dependent increase observed for SW480 wild cells lack αγβ6 expression(t=0.47,P＞0.05),MMP-9 secretion for SW480 wild cells was(3.9±1.7)× 10-7 ng/cell at hish cell density and(3.8 ±0.7)×10-7 ng/cell at low eell density(P＞0.05),respectively. Gelatin zymography assay also indicated that the level of MMP-9 in SW480 B6 cells expressing αγβ6 was evidently higher at high density than at low density, however no density-dependent increase observed for SW480 wild cells and HaCaT cells. Conclusions High cell density induces integrin αγβ6 expression and promotes MMP-9 secretion in colon cancer cells, which constitutes the basis for a self-perpetuating system of tumor infiltrating growth in colon cancer progression.

In this study, the current status for breast diseases in a region with high-incidence of cervical cancer were epidemiologically investigated. From March to August, 2009, 17618 women, from Wufeng area of Hubei province, China, were recruited to screen breast diseases by using breast infrared diagnostic apparatus. Other diagnostic methods, such as B-mode ultrasound, X-ray mammography, needle biopsy and pathological examination were, if necessary, used to further confirm the diagnosis. The screening showed that 5990 of 17618 cases (34.00%) had breast diseases, 5843 (33.16%) had mammary gland hyperplasia, 48 (0.27%) had breast fibroadenoma, 11 (0.06%) had breast carcinoma, and 88 (0.50%) had other breast diseases. The peak morbidity of breast cancer was found in the women aged 50-60 ages. The morbidity of breast cancer was significantly increased in women elder than or equal to 50 years old (n=8, 0.157%) in comparison with that in the subjects younger than 50 years old (n=3, 0.024%) (u=2.327, P<0.05). It was shown that the occurrence of breast diseases was concentrated in women aged 20-40 years, while the total morbidity reached its peak at the age of 30 years and then decreased sharply after age of 40. Compared with the patients elder than or equal to 40 years old (n=3289, 27.46%), the morbidity rate of breast diseases was significantly increased in women less than 40 years old (2648 cases, 47.18%; P<0.001). However, there was no significant difference in the morbidity of breast diseases between the age group of 20-29 years and that of 30-39 years (P=0.453), and both of them were high. There was no significant association between the morbidity of breast diseases and cervical cancer. Since the morbidity of breast diseases was higher among young women, more attention should be paid to the screening of breast diseases among young women for early diagnosis.

OBJECTIVE: To detect potential variant in an ethical Han Chinese pedigree affected with breast cancer. METHODS: The proband and her relatives were subjected to next-generation sequencing using a target capture sequencing kit containing 121 cancer-related genes. Candidate variants were selected by analysis of their type, frequency in population, and segregation with the phenotype. Candidate variant was verified by Sanger sequencing and TA cloning. RESULTS: A c.2013_2014ins GT variant was detected in the BRCA1 gene among all breast cancer patients from this pedigree but not among healthy females. The variant was not recorded in the 1000 Genome Project database or the Exome Aggregation Consortium (ExAC) database. The frameshifting insertion was predicted to form an premature stop codon in gene transcript and can give rise to a truncated protein. CONCLUSION The BRCA1 c.2013_2014ins GT variant probably underlies the pathogenesis of breast cancer in this Chinese pedigree.
