Objective: To analyze and compare therapy responses, outcomes, and incidence of severe hematologic adverse events of flumatinib and imatinib in patients newly diagnosed with chronic phase chronic myeloid leukemia (CML) . Methods: Data of patients with chronic phase CML diagnosed between January 2006 and November 2022 from 76 centers, aged ≥18 years, and received initial flumatinib or imatinib therapy within 6 months after diagnosis in China were retrospectively interrogated. Propensity score matching (PSM) analysis was performed to reduce the bias of the initial TKI selection, and the therapy responses and outcomes of patients receiving initial flumatinib or imatinib therapy were compared. Results: A total of 4 833 adult patients with CML receiving initial imatinib (n=4 380) or flumatinib (n=453) therapy were included in the study. In the imatinib cohort, the median follow-up time was 54 [interquartile range (IQR), 31-85] months, and the 7-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.2%, 88.4%, 78.3%, and 63.0%, respectively. The 7-year FFS, PFS, and OS rates were 71.8%, 93.0%, and 96.9%, respectively. With the median follow-up of 18 (IQR, 13-25) months in the flumatinib cohort, the 2-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.4%, 86.5%, 58.4%, and 46.6%, respectively. The 2-year FFS, PFS, and OS rates were 80.1%, 95.0%, and 99.5%, respectively. The PSM analysis indicated that patients receiving initial flumatinib therapy had significantly higher cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) and higher probabilities of FFS than those receiving the initial imatinib therapy (all P<0.001), whereas the PFS (P=0.230) and OS (P=0.268) were comparable between the two cohorts. The incidence of severe hematologic adverse events (grade≥Ⅲ) was comparable in the two cohorts. Conclusion: Patients receiving initial flumatinib therapy had higher cumulative incidences of therapy responses and higher probability of FFS than those receiving initial imatinib therapy, whereas the incidence of severe hematologic adverse events was comparable between the two cohorts.

AIM:To investigate the regulatory effect of NADPH oxidase-4 (NOX-4) on PI3K signaling path-way in transforming growth factor-β1 (TGF-β1)-induced collagen type Ⅰ (collagen Ⅰ) synthesis from lung cancer cells and the mechanisms. METHODS:Human lung cancer A549 cells were cultured in vitro and stimulated with TGF-β1. The ex-pression of NOX family and collagen family at mRNA and protein levels as well as the PI3K class Ⅰ catalytic subunits and the activation of PI3K signaling pathway was measured. A549 cells were pre-treated with NOX-4 inhibitor diphenyleneiodo-nium (DPI), and the expression of collagen Ⅰ at mRNA level as well as the PI3K class Ⅰ catalytic subunits and the activa-tion of PI3K signaling pathway was measured upon TGF-β1 stimulation. RESULTS:TGF-β1 stimulated the expression of NOX-4 and collagen Ⅰ at mRNA and protein levels as well as the expression of PIK3CD and the activation of PI3K signaling pathway at a dose- and time-dependent manner. NOX-4 inhibitor DPI partly reversed TGF-β1-induced collagen Ⅰ expres-sion. Inhibition of NOX-4 down-regulated the degree of TGF-β1-stimulated activation of PI3K signaling pathway without effect on the expression of PIK3CD. CONCLUSION:NOX-4 participates in TGF-β1-induced collagen Ⅰ synthesis from lung cancer cells via regulating the activation of PI3K signaling pathway. TGF-β1/NOX-4/PI3K signaling pathway axis acts as a regulatory role in collagen Ⅰ synthesis from lung cancer cells.

To investigate the effect of notoginsenoside Ft1(Ft1) on proliferation, migration and apoptosis of breast cancer cells, we conducted several assays including CCK-8 assay, EdU staining, single cell migration assay and Hoechst 33258 staining. The effect of Ft1 on expression of apoptosis related proteins, HIF-1α, PI3K/Akt/mTOR/p70S6K and MAPK pathways was examined with Western blot. Ft1 could significantly reduce cell survival and inhibit cell proliferation in breast cancer cells in a dose-dependent manner. Ft1 also increased chromatin condensation of MDA-MB-231 cells. Furthermore, Ft1 decreased protein expression of Bcl-2 and HIF-1α and increased expression of cleaved caspase 3 in MDA-MB-231 cells after 12 h treatment. Ft1 significantly down-regulated the levels of p-Akt, p-mTOR and p-p70S6K as well as p-ERK1/2, but up-regulated that of p-JNK. Ft1 significantly inhibited the level of p-EGFR (Tyr1068) and p-EGFR (Ser1046/1047) in MDA-MB-231 cells. Finally, Ft1 significantly inhibited the migration path length and velocity of HS578T cells when used at the concentration without affecting cell viability. Thus, Ft1 exhibited multiple antitumor effects including inhibition of cell survival and migration, promotion of cell apoptosis in breast cancer cells. Suppression of HIF-1α via Akt/mTOR/p70S6K and MAPK pathways may be involved in the pharmacological effect of Ft1 on cell proliferation and apoptosis of breast cancer cells.

OBJECTIVETo estimate the size of female sex workers and clients in Taizhou city.

METHODSA household survey using network scale-up method (NSUM) was conducted among the 3000 community residents in Taizhou city from August to October in 2011, which aimed to estimate the social network size (c value) of Taizhou residents, and the c value was adjusted by demographic characteristics, back estimation and outlier elimination. Using the adjusted c value, the number of acquaintance of female sex workers or clients and the respect level toward female sex workers or clients were used to estimate the size of female sex workers and clients.

RESULTSA total of 2783 valid questionnaires were collected, among which 1380 (49.6%) were collected from Taixing city, 1403 (50.4%) were collected from Jingjiang city. 1334 respondents were male (47.9%) and 1449 (47.9%) respondents were female. The mean age was (39.4 ± 10.7) years. The average personal social network size using original data for Taizhou residents was 525, which differed from place, sex, age, educational level and marriage status. Using the remaining known populations through back estimation, the social network size was 419 and became 424 after the elimination of outliers. The estimated population size for female sex worker was 6370 (95%CI: 5886 - 6853), which accounted for 0.52% (6370/1 229 980) of the total number of female aged from 15 to 49. The estimated population size for clients was 15 202 (95%CI: 14 560 - 15 847), which accounted for 1.28% (15 202/1 190 340) of the total number of males aged from 15 to 49 and the ration of clients to female sex worker was 2.39:1.

CONCLUSIONNSUM is an easy and quick way to estimate the size of female sex workers or clients, but the estimated sizes are subject to bias and error due to estimate effect and sample representativeness.

OBJECTIVETo investigate the effect of mito chondrial K(ATP) channels (mitoK(ATP)) inhibitor 5-hydroxydecanoate(5-HD) on chronic hypoxic pulmonary artery hypertension (CHPAH) rats and its underlying mechanisms.

METHODSForty-eight male SD rats were equally divided into 4 groups randomly (n=12): normal group, hypoxia group, hypoxia + 5-HD group, hypoxia + Diazoxide group. Except the first group, the other three groups were put into hypoxic [O2 (10.0% +/- 0.3%] and nonrmobaric chamber for four weeks to establish chronic hypoxic model and received different interference. When the interference completed, right heart catheter was used to detect the mean pulmonary arterial pressure (mPAP) of each rat and PKC-alpha mRNA expression in pulmonary arteries was detected by reverse transcription-polymerase chain reaction (RT-PCR) and protein expression by Western blot.

RESULTS(mPAP was much higher in hypoxia group than that in normal group (P < 0.01) while in hypoxia + 5-HD group and hypoxia + diazoxide were decreased significantly compared to hypoxia group (P < 0.01). (2) The protein and mRNA levels of PKC-alpha in the hypoxic group were higher than those in normal group (P < 0.05).

CONCLUSION5-HD plays a protective role on CHPAH. The mechanism of its effect may be attributed to inhibiting MitoK(ATP).

OBJECTIVETo summarize the experience in diagnosis and treatment of arrhythmogenic right ventricular cardiomyopathy (ARVC) in children.

METHODSA total of 14 children (7 females and 7 males) with ARVC were involved. The cases underwent electrocardiography, echocardiography, cardiac CT or MRI examinations. All cases were treated with sotalol or amiodarone in combination with propranolol. In 2 cases with drug-refractory ventricular extrasystoles, catheter ablation treatment was performed. In 6 cases with obvious impaired ventricular function, additional pharmacological therapy including vasodilators, diuretics, and digitalis were given.

RESULTSVentricular extrasystoles occurred in all 14 cases and ventricular tachycardia in 8 cases. Ten cases showed Epsilon wave on electrocardiography. All 14 cases had enlarged right ventricle and reduced right ventricular ejection fraction. CT or MRI examination showed right ventricular dilatation and a thinned wall of right ventricle in 10 cases. Ventricular extrasystoles or tachycardia disappeared in 7 cases and was reduced in 4 cases after treatment. The two children receiving catheter ablation treatment did not present ventricular extrasystoles or tachycardia in a 3-month follow-up. The heart function was improved in the 6 children with obvious impaired ventricular function after pharmacological therapy.

CONCLUSIONSThe clinical manifestations are diverse in children with ARVC. A definite diagnosis of ARVC should be based on a combination of electrocardiography and echocardiography examinations. Pharmacological therapy is effective partially. Catheter ablation treatment appears to be a promising option in patients with drug-refractory ventricular extrasystoles.
