Interferon induced transmembrane protein (IFITM is a recently discovered antiviral protein family in the cell,which inhibit many with or without coated virus replication to have antiviral effects.At the same time,some recent studies show that IFITM3 plays an important role in migration of a variety of human tumor cells and stem cells.While the mechanism in human tumor occurrence,development and diffusion transfer of IFITM3 is still unclear.This paper is aim to summarize the research progress and direction of IFITM3 protein in human tumors.

Objective To investigate the effects of Krüppel like factor 4 (KLF4)on matrix metalloproteinase 9 (MMP9)ex-pression in hepatocellular carcinoma(HCC).Methods A total of 50 primary hepatocellular carcinoma samples and their correspond-ing adjacent tissues specimens were collected.The expression of KLF4 and MMP9 were detected by IHC,Western blot and qRT-PCR.After KLF4 gene was transfected into hepatocellular carcinoma cell line (HepG2 cell line),the expressions of KLF4 and MMP9 were conformed by qRT-PCR and Western blot.Migration and invasion of HepG2 cell line transfected by KLF4 were detec-ted by wound-healing assay and invasion assay.Results Compared to corresponding adjacent tissues,The expression of KLF4 was significantly lower in HCCs(P <0.05),and MMP9 expression was remarkably higher in HCCs(P <0.05).KLF4 over-expression inhibited the expression of MMP9 on the protein and mRNA levels.Wound-healing assay and invasion assay confirmed that KLF4 regulated cell invasion and migration through regulating MMP9 expression.Conclusion KLF4 showed low expression in HCCs,and MMP9 was overexpressed.Up-regulation of KLF4 could decrease the expression of MMP9 in HepG2 cell line,which inhibited inva-sion and migration.

Metastatic seminal vesicle carcinoma is rare in clinic. The case of renal clear cell carcinoma metastasis to the seminal vesicle gland is more rare, which is difficult to be identified with bladder, prostate and colorectal tumors. In November 2017, 1 case of renal clear cell carcinoma metastasis to the left side of the seminal vesicle gland was admitted in our hospital.Laparoscopy seminal vesicle metastasis tumor resection was performed. Regular bladder irrigation and sunitib oral intake were conducted. No evidence of local recurrence was found within 19 months follow-up.

Hereditary leiomyomatosis and renal cell cancer (HLRCC) syndrome is a rare hereditary disease and characterized by cutaneous leiomyoma, uterine leiomyoma and/or renal cell carcinoma, but rarely associated with vena cava embolism. We treated 1 case of HLRCC syndrome patients with inferior vena cava tumor emboli (Mayo grade Ⅳ), confirmed after genetic testing, the patient and her family refused further treatment. The patient died after two months of follow-up after discharge.

Objective To evaluate the application value of simultaneous amplification and testing for Myco-bacterium tuberculosis(SAT-TB)in evaluating the curative effect of initial treatment of smear-positive pul-monary tuberculosis patients.Methods A total of 62 newly treated smear positive pulmonary tuberculosis pa-tients from June 2022 to June 2023 in Guangzhou Panyu District Chronic Disease Control Station were selected as the study objects,and the curative effect was evaluated by liquid-based sandwich cup method,Roche culture method and SAT-TB detection method.All patients received the standard anti-tuberculosis treatment regimen of 2HRZE/4HR standard regimen,and sputum samples were detected by liquid-based sandwich cup method,Roche culture method,and SAT-TB detection method at the 2nd,4th,and 8th week of treatment,respectively.Results Among 62 patients,54 cases were positive and 8 cases were negative using Roche culture method,47 cases were positive and 15 cases were negative using SAT-TB detection method.60 cases were positive and 2 cases were negative by Mycobacterium tuberculosis(MTB)-DNA test.The positive rates of the three methods were 87.10%(54/62),75.81%(47/62)and 96.77%(60/62),respectively.Taking Roche culture method re-sults as the standard,the sensitivity of SAT-TB detection method and MTB-DNA was 97.87%(46/47)and 90.00%(54/60),and the specificity was 46.67%(7/15)and 100.00%(2/2),respectively.There were signifi-cant differences between Roche culture method and SAT-TB detection method and MTB-DNA test(x2=20.070,P<0.05,x2=13.985,P<0.05),the difference between the results of SAT-TB detection method and MTB-DNA test was also statistically significant(x2=8.365,P<0.05).The negative conversion rates of MTB in sputum samples were 69.35%(43/62),29.03%(18/62)and 41.94%(26/62)at the 2nd,4 th,and 8 th weeks,respectively.77.42%(48/62),59.68%(37/62),58.06%(36/62),82.26%(51/62),79.03%(49/62),75.81%(47/62).There were significant differences in the negative conversion rates of MTB in sputum sam-ples between SAT-TB and liquid-based sandwich cup method at the 2nd and 4th weeks(x2=8.365,P<0.05,x2=4.465,P<0.05),while there was no significant difference between the results of Roche culture method at the 2nd,4th and 8th weeks(x2=1.726,P>0.05,x2=0.000,P>0.05,x2=0.046,P>0.05).Conclusion The use of SAT-TB detection method in clinical practice to evaluate the efficacy of smear positive pulmonary tuberculo-sis patients could accurately and quickly assess the negative conversion rate and treatment effect of patients,and provide a reliable basis for guiding clinical treatment.It could be considered as an effective auxiliary diag-nosis and evaluation method of curative effect,worthy of promotion and practical application.

Objective To sort out the development history of disease control informatization in Hubei, and provide reference for the establishment of the "Hubei model" of disease control informatization. Methods To understand the development process through data access and site investigation. Result Hubei CDC has built a provincial and municipal two-level data center; built a full-coverage security network; built a full traceable immune planning system; built a provincial, city, and county three-level video conference system; established a professional disease Control the information team. Conclusion The "Hubei model" of disease control informationization has a solid foundation. It will adhere to the development concept of people as the core, business as the problem-oriented, big data as the means, multi-point trigger as the benchmark, and network security as the foundation. Play the role of technical support and information leadership in the control business.
