Objective To analyze the influencing factors and outcomes of atrial septal defect (ASD) and ventricular septal defect (VSD) occlusion guided by echocardiography. Methods We retrospectively analyzed the clinical data of 188 patients receiving transthoracic and percutaneous transcatheter closure of ASD and VSD from July 2009 to July 2017 in our department, including 74 males and 114 females, aged 13.48±13.53 years ranging from 1 to 65 years. Results Fifty-three ASD patients accepted transthoracic closure surgery, of whom 4 patients were difficult to close and 6 patients failed to close; 24 patients underwent percutaneous transcatheter ASD occlusion surgery, of whom 3 were difficult to close and 1 failed in occlusion; 108 VSD patients implemented transthoracic closure surgery, of whom 10 patients were difficult to close and 5 patients failed in closure; 9 VSD patients underwent percutaneous transcatheter closure, of whom 5 failed and then was converted to transthoracic closure. Our study showed that too large or too small aperture was the independent risk factor. Two kinds of closure surgery had their own advantages and disadvantages. The special type of VSD was the influencing factor of transthoracic closure. Conclusion When the ASD diameter≥25 mm, transthoracic closure is the best choice to avoid the use of large occluder. When the ASD diameter<25 mm, percutaneous closure surgery is the best choice. When the ASD diameter≥35 mm, it is best to give up the closure operation. Technical improvements can significantly raise the closure success rate of the subarterial VSD. For the entry diameter>10 mm and membranous aneurysm with multi-break, occlusion surgery should be avoided in VSD.

AIM:To isolate and culture tumor stem cells in human retinoblastomas (RTSC). METHODS: Retinoblastoma (RB) single cells acquired from fresh tumors of RB patients by enzyme digestion were seeded in serum-free medium at a density of 1?10~8 cells/L. Clonal cultures were plated at a density of 1?10~6 cells/L. Secondary tumor spheres were triturated again and passaged in fresh medium. The sphere-forming, proliferation and differentiation assays were performed. RT-PCR and immunocytochemistry were performed to identify the RTSC and differentiated cells. RESULTS: All RB tumors studied produced proliferating neurosphere-like tumor spheres, which were also passaged multiple times. These tumor spheres had the capability to self-renew, proliferate in SFM medium, expressed retinal progenitor cell related genes, and differentiated into neurons and glia when they were transferred to differentiation conditions.CONCLUSION:Our findings demonstrated that there were subsets of tumor stem cells resembling retinal progenitor cells in human RB, which can be isolated, cultured in SFM. The RTSC may be original cells of RB tumor, and also become the new target of tumor therapy.

Aim To investigate the effect and mecha-nism of quercetin combined with cisplatin on prolifera-tion and apoptosis of human osteosarcoma cell line MG-63 . Methods MG-63 cells were treated with quercetin alone or combined with cisplatin. Cellular morphologic changes were observed under inverted phase contrast microscope. The effects of proliferation inhibition were assayed by CCK-8 method. The combination effect was judged through Chou-Talaly analysis. The apoptosis ra-tios of cells were analyzed by flow cytometry. The gene expression of Bcl-2 and caspase-3 was detected by RT-PCR assay. The protein expression of Bcl-2 and caspase-3 was measured by Western blot assay. Re-sults Quercetin alone or combined with cisplatin could inhibit the proliferation, but induce the apoptosis of MG-63 cells. Combination of quercetin and cisplatin revealed a synergistic effect on cell proliferation and apoptosis as it reduced the expression of Bcl-2 but en-hanced that of caspase-3 at both gene and protein lev-els. Conclusion Synergistic effect of quercetin com-bined with cisplatin on cell proliferation and apoptosis of MG-63 cells is possibly due to reduction of Bcl-2 and enhancement of caspase-3 expression.

Background::The disease burdens for endometrial cancer (EC) vary across different countries and geographical regions and change every year. Herein, we reported the updated results of the Global Burden of Disease Study 2019 on EC with respect to age-standardized incidence and mortality from 1990 to 2019.Methods::The annual percentage change (APC) of incidence and mortality was evaluated using joinpoint regression analysis to examine the temporal trends during the same timeframe in terms of the global landscape, different sociodemographic indices (SDI), and geographic regions. The relationship between Human Development Index (HDI) and incidence and mortality was additionally explored.Results::The age-standardized incidence rates (ASIRs) revealed a significant average global elevation by 0.5% per year (95% confidence interval [CI], 0.3–0.7; P <0.001). The age-standardized mortality rates (ASMRs), in contrast, fell by an average of 0.8% per year (95% CI, ?1.0 to ?0.7; P <0.001) worldwide. The ASIRs and ASMRs for EC varied across different SDIs and geographical regions. We noted four temporal trends and a significant reduction by 0.5% per year since 2010 in the ASIR, whereas we detected six consecutively decreasing temporal trends in ASMR during the entire period. Notably, the estimated APCs were significantly positively correlated with HDIs (ρ = 0.22; 95% CI, 0.07–0.35; P = 0.003) with regard to incident cases in 2019. Conclusions::Incidence rates for EC reflected a significant increase overall (although we observed a decline since 2010), and the death rates declined consecutively from 1990 to 2019. We posit that more precise strategies can be tailored and then implemented based on the distinct age-standardized incidence and mortality burden in different geographical areas.

Objective:
To observe the efficacy and safety of de novo combination of Lamivudine(LAM) and Adefovir Dipivoxil (ADV) therapy counter to Entecavir (ETV) monotherapy in patients with chronic hepatitis B (CHB)- related compensated liver cirrhosis.
Methods:
Patients with chronic hepatitis B-related compensated cirrhosis who were initially treated with LAM and ADV for more than 1 year were randomly assigned to two groups, one half replaced with ETV monotherapy, and the other half continued LAM and ADV co-therapy. Liver biochemistry, renal biochemistry, estimated glomerular filtration rate, alpha-fetoprotein, HBV serology markers and serum HBV DNA were measured every 3 months. Urine β2-microglobulin was measured every 6 months And retinol binding protein, followed up for 3 years. The mean values of the two groups were compared with t-test, and the rate of comparison was analyzed by x2 test.
Results:
A total of 580 cases were collected, 290 cases were replaced with ETV monotherapy, the other 290 patients continued to LAM and ADV combination therapy. In the ETV group, the rates of HBV DNA negative conversion at 1 year, 2 years and 3 years were 77.6%, 84.5% and 94.5% respectively, while the HBV DNA negative conversion rates at 1, 2 and 3 years in the LAM and ADV combination groups were 69.3%, 73.4% and 80.3% respectively. Among them, the negative rates of HBV DNA in the second year and the third year were

Objective:To develop a tetramer probe targeting fibroblast activation protein (FAP), named 1, 4, 7, 10-tetraazacyclododecane-1, 4, 7, 10-tetraacetic acid (DOTA)-4P(FAP inhibitor (FAPI)) 4, evaluate its biodistribution and PET image in FAP-positive-tumor bearing nude mice, and explore its feasibility as a novel radio-regent for treatment of FAP-positive tumor. Methods:FAP tetramer probe was constructed on the FAPI-46 motif with four mini-polyethylene glycol (PEG)(PEG 3) spacers between the four FAPI motifs, denoted as 4P(FAPI) 4. DOTA was used as the chelator for radiolabeling with 68Ga and 177Lu. The FAP binding characteristics were test by in vitro cell competitive binding experiment. Small-animal PET, in vivo biodistribution, and radionuclide targeting therapy were performed in HT-1080-FAP tumor bearing nude mice ( n=39). Independent-sample t test was performed to analyze tumor uptake data, and two-factor repeated measures analysis of variance was utilized to compare tumor volume data in radioactive isotope therapy. Results:Cell experiment showed that FAPI-tetramer and FAPI-monomer had similar half maximal inhibitory concentration values (3.29 and 2.15 nmol/L). 68Ga/ 177Lu radiolabeled FAPI-tetramer had better tumor uptake and retention than FAPI-monomer in small-animal PET and in vivo biodistribution experiment, with the tumor uptake for 177Lu-DOTA-4P(FAPI) 4 and 177Lu-FAPI-46 at 48 h of (18.72±1.32) vs (2.72±1.20) percentage activity of injection dose per gram of tissue (%ID/g) ( t=15.55, P<0.001). 177Lu-DOTA-4P(FAPI) 4 group showed best anti-tumor efficacy compared with 177Lu-FAPI-46 and control group in radionuclide targeting therapy. On the 2nd day after the start of treatment, the tumor volume in the tetramer treatment group was significantly smaller than that in the control group (mean difference 67.19 mm 3, P=0.049); on the 14th day after the start of treatment, the tumor volume in the tetramer treatment group was significantly smaller than that in the monomer treatment group (mean difference 414.33 mm 3, P=0.005). Conclusion:FAPI-tetramer can improve tumor uptake and retention ability compared with FAPI-46, and 177Lu-DOTA-4P(FAPI) 4 can be a promising radio-agent for FAP-positive tumor therapy.

OBJECTIVE:
To investigate and analyse the features of treatment behavior and standardized therapeutic status of patients with psoriatic arthritis (PsA).
METHODS:
Out patients diagnosed with PsA in People's Hospital of Peking University, Haidian Hospital, People's Hospital of Jianyang City, Central Hospital of Xinxiang City, Integrated Traditional Chinese and Western Medicine Hospital of Cangzhou City, The Third Hospital of Hebei Medical University from February to June 2018 were enrolled in this investigation. The data including gender, age of onset, course of disease, site of first consulting department, time of the first visit and definite diagnosis, follow-up interval, and use of conventional disease modifying anti-rheumatic drugs (cDMARDs) and biological DMARDs (BioDMARDs) were collected and analyzed.
RESULTS:
In the cross-sectional study, 133 PsA patients were investigated. The mean age of onset was (47±11) years, the male to female ratio was 1.3:1, and mean disease duration was (16±8) years. Rheumatology department was the most common site of first hospital visit (37.6%, 50/133). Orthopedics department and dermatological department were visited by 24.1% (32/133) and 23.3% (31/133), respectively. Ratio of definite diagnosis was the highest in rheumatology department which was 78% (39/50). The ratio of definite diagnosis of dermatological department was the second highest, which was 19.4% (6/31). The mean definite diagnosed time was 7.6 months since the first visit of PsA patients, and diagnosed time was the shortest in rheumatology department, which had statistical significance. 37% PsA patients were treated appropriately in 3 months, 17.3% PsA patients were treated in 3-6 months and 40.2% patients with PsA visited their doctor more than once a year. 48.8% patients hadn't received standardized treatment before visit, and one third patients never received the therapy of DMARDs. Methotrexate was the most commonly used cDMARDs (58.3%), followed by leflunomide (20.5%) and BioDMARDs (19.7%), and biologicals were tumor necrosis factor antagonists.
CONCLUSION
In this multi-center study, the first visit department of PsA patients was widely distributed, and most patients were definitely diagnosed in Rheumatology Department. The time of their first visit and definite diagnosis were delayed due to multi factors. Nearly half of the patients did not receive standardized treatment.
