OBJECTIVE:
To investigate the efficacy and safety of arsenic trioxide combined with ATRA and chemo- therapy for treatment of relapsed acute promyelocytic leukemia (APL) patients.
METHODS:
The clinic data of 25 patients with relapse APL treated in our hospital from 1996 to 2013 were collected and analyzed. Among the 25 patients, 15 patients suffered first-time hematological relapse (HR), and the other 10 patients showed first-time molecular relapse (MR). The patients with first-time replase were treated with ATO+ATRA+Anthracycline re-induction chemotherapy. The clinical features, complete remission (CR) rate, overall survival (OS), disease-free survival (DFS) and adverse events after re-induction therapy were analyzed.
RESULTS:
Fourteen of 15 hematological relapsed patients achieved the second-time hematological complete remission (CR2) after re-induction therapy except one patient died of bleeding complication during the re-induction. 8 of 14 patient showed molecular complete remission (CRm) after two cycles of therapy with this regimen. Totally, eleven out of the 14 HR patients were alive without disease till the last follow-up, and 3 of the 14 HR patients died because of bleeding complications. All of the 10 molecular relapsed patients received the second CRm after treated by the regimen. Among these 10 patients, 6 patients suffered only once relapse and continued with the molecular CR2 status, and for the other 4 patients with more than two-relapses, only 1 survived untill 89.3 months after achieved second-time CRm, and other 3 patients died because of bleeding complications.
CONCLUSION
For relapsed APL patients, the treatment with ATO+ATRA+chemotherapy regimen after relapse still shows encouraging efficacy, no matter whether or not the application of ATO in the previous regimens. In addition, patients with more than two molecular relapses show a poor prognosis.

For sexual reproduction, oocytes are mammalian female germ cells that provide the majority of maternal genetic material for early stage embryo production and development. Early stage embryos begin the process of multicellular organism formation through cell differentiation. Studies on mammalian female germ cells (oocytes) not only reveal its unique physiological characteristics, but also help understand the mechanism involved in cell differentiation of other cell types. However, because it is difficult to culture in vitro, our understanding of the function of oocytes and early stage embryos remains very limited. Gene editing or manipulation is one of the most commonly used method, which is also useful in the field of gametes study. In this review, we summarized the principles, advantages and disadvantages of techniques, which include conditional knockout, RNA interference, Morpholino, Trim-Away and antibody-mediated inhibition of protein function, currently used for gene manipulation in oocytes and early stage embryos. We also discuss the issues the investigators need to consider. Finally, we highlight the future directions for gene manipulation or editing in female germ cells and early stage embryos.

Objective To analyze the genetic characteristics of the hemagglutinin (HA) and neuraminidase (NA) genes of influenza B viruses isolated in Yancheng City from 2015 to 2017. Methods The throat swab specimens of influenza-like illness( ILI) from sentinel surveillance hospital and outbreak sites were collected and sent to Yancheng CDC for virus nucleic acids and virus isolation testing. After validation with serological tests, eighteen strains of influenza B virus isolates were selected to amplify their HA1 and NA genes through RT-PCR assay. Their molecular characteristics of the obtained viral HA1 and NA gene sequences were analyzed using bioinformation software from three aspects, including nucleic acid level, amino acid level and molecular evolution level. Results Basically, the clustering relationships and the branche patterns between HA1 and NA genes from the 18 Yancheng influenza B virus strains were similar. The Yamagata lineage strains in 2015 were distributed in the Yamagata Clade 3 branch, belonging to Phuket/3073 strains. The Victoria lineage strains in 2016-2017 were distributed in the Victoria Clade 1A branch, belonging to Brisbane/60 strains. D196N substitution was detected on HA1 protein in all of Yamagata lineage strains at 190-helix epitope; Amino acid substitutions of victoria lineage strains involved two antigenic epitopes, 117 and 129 sites of 120-loop epitope and 197 and 199 sites of 190-helix epitope. No Intra-lineage or inter-lineage rearrangements occurred in Yancheng strains. Eighteen influenza B strains had no mutations in catalytic residues and drug resistant sites of NA genes. Conclusion The Yamagata strains well matched with vaccine strain B/Phuket/3073/2013. The HA1 and NA genes of victoria lineage strains circulated in Yancheng City during 2016 to 2017 are changing gradually. The accumulation of these mutations will result in antigenic drift of victoria lineage strains and increase the mismatch of the IFV field stains with the available vaccine strains, which may reduce the protective effect of flu vaccine.

Cis-3-O-p-hydroxycinnamoyl ursolic acid (HCUA), a triterpenoid compound, was purified from Elaeagnus oldhamii Maxim. This traditional medicinal plant has been used for treating rheumatoid arthritis and lung disorders as well as for its anti-inflammation and anticancer activities. This study aimed to investigate the anti-proliferative and apoptotic-inducing activities of HCUA in oral cancer cells. HCUA exhibited anti-proliferative activity in oral cancer cell lines (Ca9-22 and SAS cells), but not in normal oral fibroblasts. The inhibitory concentration of HCUA that resulted in 50% viability was 24.0 µM and 17.8 µM for Ca9-22 and SAS cells, respectively. Moreover, HCUA increased the number of cells in the sub-G1 arrest phase and apoptosis in a concentration-dependent manner in both oral cancer cell lines, but not in normal oral fibroblasts. Importantly, HCUA induced p53-mediated transcriptional regulation of pro-apoptotic proteins (Bax, Bak, Bim, Noxa, and PUMA), which are associated with mitochondrial apoptosis in oral cancer cells via the loss of mitochondrial membrane potential. HCUA triggered the production of intracellular reactive oxygen species (ROS) that was ascertained to be involved in HCUA-induced apoptosis by the ROS inhibitors YCG063 and N-acetyl-L-cysteine. As a result, HCUA had potential antitumor activity to oral cancer cells through eliciting ROS-dependent and p53-mediated mitochondrial apoptosis. Overall, HCUA could be applicable for the development of anticancer agents against human oral cancer.

YKL-40, a secreted glycoprotein, may serve as an autoantigen, which mediates multiple inflammatory diseases and cancers. A high YKL-40 serum level is correlated with metastasis and poor survival in a variety of human cancers. However, the role of YKL-40 in dogs is still under evaluation. Herein, we examined the associations between plasma YKL-40 level and YKL-40 autoantibody (YAA) titers with malignancy and prognosis in canine cancer. Plasma levels of YKL-40 in healthy dogs (n = 20) and in dogs (n = 82) with cancer were evaluated using enzyme-linked immunosorbent assay. Our results indicated that plasma YKL-40 levels were significantly higher (p < 0.01) in dogs with cancer than in healthy dogs. A significant decrease in the YAA titers was detected in the dogs with cancer when compared with those of the healthy dogs (p < 0.05), although the change was not correlated with the YKL-40 levels. Among the dogs with cancer, plasma YKL-40 levels in the dogs that later relapsed or had metastasis were significantly higher than in the dogs with no signs of relapse (p < 0.01) or metastasis (p <0.05). The relapse and metastasis rates were significantly higher in the high YKL-40 group (> 180 pg/mL) than in the low YKL-40 group (< 180 pg/mL). The results imply that plasma YKL-40 levels might have the potential to be developed as a marker of malignancy progression and prognosis in canine cancers.

OBJECTIVE: Autonomic imbalance is considered a psychopathological mechanism underlying major depressive disorder (MDD). Heart rate variability (HRV) is an index for autonomic activation. Poor sleep quality is common among patients with MDD. HRV biofeedback (BF) has been used for regulating autonomic balance among patients with physical illness and mental disorders. The purpose of present study was to examine the effects of HRV-BF on depressive symptoms, sleep quality, pre-sleep arousal, and HRV indices, in patients with MDD and insomnia. METHODS: In this case-controlled study, patients with MDD and Pittsburgh Sleep Quality Index (PSQI) score higher than 6 were recruited. The HRV-BF group received weekly 60-minute protocol for 6 weeks, and the control group who have matched the age and sex received medical care only. All participants were assessed on Beck Depression Inventory-II, Back Anxiety Inventory, PSQI, and Pre-Sleep Arousal Scale. Breathing rates and electrocardiography were also performed under resting state at pre-testing, and post-testing conditions and for the HRV-BF group, also at 1-month follow-up. RESULTS: In the HRV-BF group, symptoms of depression and anxiety, sleep quality, and pre-sleep arousal were significantly improved, and increased HRV indices, compared with the control group. Moreover, in the HRV-BF group, significantly improved symptoms of depression and anxiety, decreased breathing rates, and increased HRV indices were detected at post-testing and at 1-month follow-up, compared with pre-testing values. CONCLUSION: This study confirmed that HRV-BF is a useful psychosocial intervention for improving autonomic balance, baroreflex, and symptoms of depression and insomnia in MDD patients.

OBJECTIVE: To report our initial experience of percutaneous sacroplasty (PSP) with an interpedicular approach for treating painful sacral metastases involving multiple sacral vertebral bodies. MATERIALS AND METHODS: This study prospectively enrolled 10 consecutive patients (six men and four women; mean age, 56.3 ± 13.8 years) who underwent PSP for painful sacral metastases involving multiple sacral vertebral bodies from March 2017 to September 2018. Visual analogue scale (VAS) scores, Oswestry disability index (ODI) values, and the number of opioids prescribed to the patients were assessed before and after PSP. The procedure duration, length of hospitalization, and complications were also recorded. RESULTS: Mean VAS and ODI declined significantly from 6.90 ± 1.20 and 74.40 ± 5.48 before the procedure to 2.70 ± 1.34 and 29.60 ± 14.57 after the procedure, respectively (p < 0.01). The median number of opioids prescribed per patient decreased from 2 (interquartile range [IQR] 1-3) pre-procedure to 1 (IQR 0–3) post-procedure (p < 0.01). Nine of the 10 patients showed no or decreased opioid usage, and only 1 patient showed unchanged usage. The mean procedure duration was 48.5 ± 3.0 minutes. The average length of hospitalization was 4.7 ± 1.7 days. Extraosseous cement leakage occurred in three cases without causing any clinical complications. CONCLUSION: PSP with an interpedicular approach is a safe and effective treatment in patients with painful sacral metastases involving multiple sacral vertebral bodies and can relieve pain and improve mobility.

OBJECTIVE:
To explore the clinical pathological features of the patients with diffuse large B cell lymphoma (DLBCL) and their prognostic factors.
METHODS:
The prognosis of the clinical pathological features and their influence on prognosis of 177 patients diagnosed as DLBCL at the first visit from January 2013 to May 2017 in our hospital were analyzed retrospectively.
RESULTS:
The univariate analysis showed that overall survival (OS) and progression-free survival (PFS) were associated with later Ann Arbor stage (Ⅲ-Ⅳ) ( P<0.01, P<0.05), high performance status (ECOG score 2-4) (P<0.01, P<0.05), extranodal involvement >1 (P<0.01, P<0.05), elevated LDH level (P<0.01, P<0.05). B symptom (P<0.05) and elevated β2-MG level (P<0.05) also influenced OS. COX multivariate analysis showed that the elevated β2-MG level (P<0.05) and later stage (Ⅲ-Ⅳ) (P<0.05) have an independent influence on OS, later stage (Ⅲ-Ⅳ) (P<0.05) also independently influenced PFS. The patients with high aaIPI score (2-3) and bone marrow involvement before treatment had poor OS (P<0.01, P<0.01) and PFS (P<0.05, P<0.01).
CONCLUSION
Elevated β2-MG level can independently influence OS, and later stage (Ⅲ-Ⅳ) can independently influence both OS and PFS. High aaIPI score (2-3) and bone marrow involvement before treatment have an inferior influence on OS and PFS.
