ABSTRACT
Objective: To summarize the clinical data and prognosis of children with Philadelphia chromosome-like acute lymphoblastic leukemia (Ph-like ALL) common genes. Methods: This was a retrospective cohort study.Clinical data of 56 children with Ph-like ALL common gene cases (Ph-like ALL positive group) treated from January 2017 to January 2022 in the First Affiliated Hospital of Zhengzhou University, Henan Children's Hospital, Henan Cancer's Hospital and Henan Provincial People's Hospital were collected, 69 children with other high-risk B cell acute lymphoblastic leukemia (B-ALL) at the same time and the same age were selected as the negative group. The clinical characteristics and prognosis of two groups were analyzed retrospectively. Comparisons between groups were performed using Mann-Whitney U test and χ2 test. Kaplan-Meier method was used for survival curve, Log-Rank test was used for univariate analysis, and the Cox regression model was used for multivariate prognosis analysis. Results: Among 56 Ph-like ALL positive patients, there were 30 males and 26 females, and 15 cases were over 10 years old. There were 69 patients in Ph-like ALL negative group. Compared with the negative group, the children in positive group were older (6.4 (4.2, 11.2) vs. 4.7 (2.8, 8.4) years), and hyperleukocytosis (≥50×109/L) was more common (25% (14/56) vs. 9% (6/69)), the differences were statistically significant (both P<0.05). In the Ph-like ALL positive group, 32 cases were positive for IK6 (1 case was co-expressed with IK6 and EBF1-PDGFRB), 24 cases were IK6-negative, of which 9 cases were CRLF2 positive (including 2 cases with P2RY8-CRLF2, 7 cases with CRLF2 high expression), 5 cases were PDGFRB rearrangement, 4 cases were ABL1 rearrangement, 4 cases were JAK2 rearrangement, 1 case was ABL2 rearrangement and 1 case was EPOR rearrangement. The follow-up time of Ph-like ALL positive group was 22 (12, 40) months, and 32 (20, 45) months for negative group. The 3-year overall survival (OS) rate of positive group was significantly lower than the negative group ((72±7) % vs. (86±5) %, χ2=4.59, P<0.05). Compared with the 24 IK6-negative patients, the 3-year event free survival (EFS) rate of 32 IK6 positive patients was higher, the difference was statistically significant ((88±9) % vs. (65±14) %, χ2=5.37, P<0.05). Multivariate Cox regression analysis showed that the bone marrow minimal residual disease (MRD) not turning negative at the end of first induction (HR=4.12, 95%CI 1.13-15.03) independent prognostic risk factor for patient with Ph-like ALL common genes. Conclusions: Children with Ph-like ALL common genes were older than other high-risk B-ALL patients at diagnosis, with high white blood cells and lower survival rate. The bone marrow MRD not turning negative at the end of first induction were independent prognostic risk factor for children with Ph-like ALL common gene.

ABSTRACT
OBJECTIVE: To explore the in vitro and in vivo experimental study of thioredoxin-1(Trx1) inhibitor 1-methylpropyl 2-imidazolyl disulfide (PX-12) promoting multiple myeloma H929 cell apoptosis, investigate the relationship between the inhibitory effect of PX-12 on H929 cells and reactive oxygen species (ROS). MATERIALS AND METHODS: Inhibition of PX-12 on H929 cells in relation to reactive oxygen species (ROS), cell cycle, and apoptosis were assessed by flow cytometry. ELISA kit, IVIS Imaging, Hematoxylin and eosin (H&E) staining and immunohistochemical staining assessment were applied to assess the anti-myeloma effect in the SCID mice model established by H929EL cells. RESULTS: PX-12 inhibited proliferation of H929 cells performed time and dose dependent style. Furthermore, it significantly induced a G2/M phase arrest of the cell cycle in H929 cells. It also increased intracellular ROS and caspase-3 activity in H929 cells indicating that cells have undergone apoptosis. There was an almost 3-5-fold decrease in tumor viability measured by the Living-Imaging system after 21 and 28 days after PX-12 injection compared with the control group. Importantly, PX-12 caused significant decrease in expression of Kappa chain in vivo assessed by immunohistochemical staining. CONCLUSIONS: The results suggest that PX-12 may be a potential strategy for the treatment of MM, and the inhibition of TRX-1 in the treatment of myeloma deserves further research.

Objective: To explore the occurrence, clinical characteristics, diagnosis and treatment of glomerulitis after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Methods: Analysis were carried out based on the clinical data of 6 patients with de novo glomerulitis following allo-HSCT hospitalized in Henan Tumor Hospital from January 2008 to December 2016, and the clinical manifestation, pathology, diagnosis, treatment and outcome were investigated. Results: The occurrence of glomerulitis was 1.26% (6/478). The median time was 447(272-1 495) d after allo-HSCT. Proteinuria and varying degrees of edema were present in all patients. Of the 6 patients, 4 patients with impaired renal function, 3 cases of hypertension, 5 cases of urine occult blood positive, 2 cases of hyperlipidemia. 5 patients underwent acute graft-versus-host disease (GVHD), 4 patients accompanied with chronic GVHD at diagnosis. Kidney pathology showed typical features of minimal change diseases in 1 patient, membranous nephropathy in 4 patients and mesangial proliferative glomerulonephritis in 1 case. Immunohistochemistry of glomerular lesions revealed that the immune complex deposition included IgG in 4 patients, C3 in 3 patients, IgM and C1q in 1 patient. Serum ANA was positive in 2 patients and serum IgG and IgM were in high level in 1 patient, respectively. Only 1 case was effective on glucocorticoid. 5 cases treated by low dose cyclophosphamide combined with mycophenolate mofetil (MMF), 2 cases achieved complete remission, and 3 cases were partial remission. Up to now, 2 cases died with lung infection, and 4 patients survived. Conclusion: The predominant pathological type of glomerulitis was membranous nephropathy. Low-dose cyclophosphamide combined with MMF was an effective treatment.

Objective: To explore the expression and prognostic significance of miR-223 in patients with mantle cell lymphoma (MCL) and to investigate the possible mechanism. Methods: Twenty-one newly diagnosed MCL patients with bone marrow involvement were enrolled in the present study, 20 healthy donors as normal control. The expression level of miR-223 and SOX11 mRNA was determined by RQ-PCR. CCK-8 and flow cytometer assays were used to analyze cell proliferation, cell cycle and apoptosis of the constructed miR-223 overexpressing MCL cell line, Granta519 cells. SOX11 protein expression level was determined by Western blot. The target gene of miR-223 was confirmed by dual luciferase reporter assay. Results: â Of the 21 newly diagnosed MCL patients, 15 were male and 6 female, the median age was 58 (37-72) years. The expression level of miR-223 was significantly down regulated in MCL patients compared with that of healthy donors (14.7±10.5 vs 1 244.1±1 935.2, P<0.001). The lower expression of miR-223 was inversely correlated with high-risk mantle international prognostic index (P=0.001), elevated LDH (P=0.001), ECOG score ≥2 (P=0.035). â¡Using the median relative expression level of miR-223 as the cutoff value, 21 MCL patients were divided into high-expression group (n=10) and low-expression group (n=11) and found that the high-expression group had a significantly superior OS (median OS: 36 vs 12 months, P=0.021). â¢In vitro results showed that compared with the control group, the proliferation of miR-223 overexpressed Granta519 cells was inhibited (the most significant reduction on 96h, P<0.001), manifested by lower proportion of cells in G2/M phase (P<0.001) and increased apoptosis (P<0.001), and the expression level of SOX11 protein in Granta519 cells was significantly lower than that of the control group. â£miR-223 could inhibited the 3' untranslated region of SOX11, and the expression level of miR-223 was significantly negatively correlated with mRNA level of SOX11 in MCL patients (r=-0.81, P<0.001). Conclusions: The expression of miR-223 was repressed in MCL and was associated with poor clinical outcomes, which may be probably attributed to its direct targeting SOX11.

OBJECTIVE: To evaluate the efficacy and safety of domestic human recombinant FSH(rhFSH)in women with anovulation of WHO group â ¡. METHODS: A randomized, blind, parallel-controlled, non-inferiority and multicenter study was performed. A total of 534 admitted to 13 hospitals from May 2008 to August 2009. There were 531 women with ovulatory disorder was included in the statistical analysis, were randomly divided into test group(domestic rhFSH, n=352)and control group(imported rhFSH, n=179). Percentage of cycle with mature follicle, ovulation rate, clinical pregnancy rate, multiple pregnancy rate, ovarian hyperstimulation syndrome(OHSS)and adverse events were observed. RESULTS: No statistical significant differences(P>0.05)were observed between the two groups in terms of the efficiency on mature follicle[91.8%(323/352)versus 88.8%(159/179)], ovulation rate[91.3%(295/323)verus 90.6%(144/159)], clinical pregnancy rate[19.2%(62/323)verus 18.2%(29/159)], the number of the follicles<14 mm, the level of serum LH and progesterone, the thickness of endometrium on the day of hCG administration. The number of follicle≥18 mm and 14 mm≤follicle<18 mm and the level of serum estradiol on the day of hCG in the test group were significantly higher than those in the control group(P<0.05). The number of days of rhFSH administration in the test group was significantly less than that in the control group[(9.8±2.2)versus(11.4± 0.6)days, P<0.05], the dosage of rhFSH was significantly lower than that in the control group[(879 ± 419)versus(1 043±663)U, P<0.05]. The multiple pregnancy rate in the test group was significantly higher than that in the control group[21%(13/62)versu 10%(3/29), P<0.05]. The incidence of OHSS and adverse events were similar between the two groups(P>0.05), and no other adverse events were observed in test group during treatment. CONCLUSION: Ovarian stimulation with domestic rhFSH is effective, safe and economical in women with anovulation of WHO group â ¡.

Two types of oestrogen-medicated intrauterine devices (IUD) were studied in ovariectomized rhesus monkeys. An oestradiol (E2) fibre-wrapped IUD that released E2 at a rate of 3.57 micrograms/cm/day, or an oestriol (E3) fibre-wrapped IUD that releases E3 at a rate of 6.4 micrograms/cm/day, was inserted in eight animals and left in place for 4 weeks. Serum levels of follicle stimulating hormone (FSH), luteinizing hormone (LH), E2 and E3 were determined by radioimmunoassay for 1 week before the IUD insertion, during the time the IUD was in place, and for 3 weeks after its removal. Uterine histology was performed at the time of IUD insertion and removal by light and transmission electron microscopy. Both E2 and E3 IUDs induced similar histological changes in the uterus, i.e. four- to five-fold increase in endometrial thickness, a shift of the gland/stroma ratio from 1:4 to 1:1, transformation to a marked pseudostratified epithelium with pronounced coiling of the glands, appearance of subnuclear and luminal secretion and, finally, change from spindle-dense stromal cells to plump eosinophilic cells. Oestradiol fibre-wrapped IUDs produced circulating E2 levels of 150-200 pg/ml during the entire 4 weeks. FSH and LH levels were decreased to an average of 55% and 65% from a castration baseline (P less than 0.001 and P less than 0.05, respectively). Oestriol fibre-wrapped IUDs produced circulating E3 levels of 100-250 pg/ml. However, FSH and LH levels were not altered in this group. The specific local oestrogenic effect of E3-IUDs without affecting the pituitary secretion of gonadotrophins, suggests their possible application in cases in which an exclusively oestrogenic effect at the uterine level, such as in Asherman's syndrome, is desired.

The performance of the gamete intrafallopian transfer (GIFT) technique, utilizing an individualized regimen of follicular induction and minilaparotomy in 45 patients with infertility of varying etiologies is reported. The induction regimen consisted of the administration of clomiphene citrate, 100 mg, from day 3 to day 7, and 150 IU FSH/LH (human menopausal gonadotropin [hMG]) from day 6 on. Human chorionic gonadotropin (hCG; 10,000 IU) was administered when at least two follicles measured 16 mm or more in diameter and when serum estradiol (E2) measurement revealed levels of 350 pg/ml per each main follicle. Up to two oocytes and 100,000 motile sperm were transferred to the fallopian tubes via the fimbria, using a catheter. Of the 45 cases, 13 became pregnant by clinical criteria (29 per cent). Of these 13 pregnancies, nine continued to term (69 per cent), three miscarried spontaneously (12 per cent) and one was an ectopic (7 per cent). Of the nine pregnancies that continued to term, five (55 per cent) were twins. Details of the GIFT procedure as well the preliminary non-human primate research studies that led to the development of the GIFT technique are discussed. It is concluded that GIFT is an excellent alternative to in vitro fertilization and embryo transfer (IVF; ET) in all cases of infertility that failed to conceive using conventional forms of therapy and in which the female partner presents at least one normal fallopian tube.
