Objective To explore the feasibility of laparoscopic operations in the treatment of ovarian benign tumors. Methods A retrospective analysis of 150 cases of ovarian benign tumors treated by laparoscopic surgery (146 cases of oophorocystectomy and 4 cases of adnexectomy) from January 1997 to October 2003 was made. Results Surgery was completed successfully in all the 150 cases and no conversions to open surgery were required. Mild extraperitoneal emphysema was observed in 2 cases and no other complications occurred. The mean blood loss was 100 ml, the mean operation time was 80 min, and the mean length of hospitalization was 4 3 days. A total of 128 cases were followed up for a mean of 3 8 years. Recurrence was found in 4 cases in 38 cases of endometriosis cysts. Among 15 patients complicated with infertility, conception occurred in 6 patients after surgery, with a pregnancy rate of 40%. Conclusions Laparoscopic surgery is safe and effective for ovarian benign tumors provided patients are properly selected.

AIM: To study the role of protein kinase B (PKB) in tryptase-induced gene expression on ECV304 cells. METHODS: The expression of PKB, transcript factor AP-1 and NF-?B P65, IL-8, JNK, p38MAPK, and the activity of PKB were measured using RT-PCR and Western blotting. RESULTS: Tryptase at concentration of 1 ?g/L increased the activity of PKB by promoting PKB phosphorylation, promoted the expression of PKB, chemokine IL-8, transcription factor AP-1 and NF-?B P65, however, no changes of JNK and p38MAPK was observed. PI3K specific inhibitor (LY294002) abolished the augment of PKB, NF-?B P65 and IL-8 expression. Antisense PKB cDNA transfection also abolished the augment of PKB, AP-1, NF-?B P65 and IL-8 expression. Though PAR2 antibody did not inhibit PKB expression, it did inhibit the phosphorylation by tryptase in ECV304 cells. CONCLUSION: These results indicate that tryptase can activate PKB through PAR2 receptor and subsequently NF-?B, AP1, IL-8 and PKB expression.

OBJECTIVETo investigate the antitumor and anti-metastatic effect of in situ transduction of adenovirus encoding cytosine deaminase (AdCD) followed by the systemic use of 5-fluorocytosine (5-FC) in the orthotopic (o.t.) prostate cancer mouse model.
METHODSThe o.t. prostate cancer model of C57BL/6 mouse was developed by o.t. inoculation of RM-1 cells to the subcapsular area of the prostate gland. In situ transduction of the CD gene, followed by systemic use of 5-FC at a daily dosage of 300 mg/kg for 14 days, was performed two days later.
RESULTSCompared with mice treated with Adbeta-gal/5-FC, 5-FC and PBS, mice of the o.t. model receiving in situ treatment of AdCD/5-FC had significant prolongation of survival and suppression of local tumor growth. More importantly, pathological observations showed that metastatic activity occurred in all mice of the PBS, 5-FC and Adbeta-gal groups including metastasis to the iliac lymph node (10/10, 10/10, 10/10) and the lung (8/10, 7/10, 7/10). However, only two out of ten had iliac lymphatic metastasis in the AdCD/5-FC group with no systemic or preaotic lymphatic metastasis, suggesting a strong metastatic inhibitory effect.
CONCLUSIONSIn situ transduction of AdCD followed by systemic use of 5-FC leads to the inhibitory effect on tumor growth and metastatic activity in the o.t. mouse model of prostate cancer. Clinically, it may be possible to treat metastatic or recurrent prostate cancer with a novel gene therapy using in situ injection techniques in future.

Objective:To investigate the efficacy and safety of ixazomib combined with lenalidomide and dexamethasone (IRd) regimen in treatment of multiple myeloma (MM) patients in the real world practice.Methods:The clinical data of 24 MM patients treated with IRd regimen from January 2019 to January 2021 in the Union Hospital, Tongji Medical College, Huazhong University of Science and Technology were retrospectively analyzed, and their efficacy and adverse reactions were analyzed. Among the 24 patients, 5 patients were relapsed and refractory (relapsed/refractory group), and 19 newly treated patients (conversion group) who responded to bortezomib induction therapy but converted to IRd regimen due to adverse reactions or other reasons.Results:The 24 patients were treated for a median of 4 cycles (2-7 cycles), with 8 cases of complete remission (CR), 6 cases of very good partial remission (VGPR), 8 cases of partial remission (PR), 1 case of disease progression (PD), 1 case of minimal response (MR), and the overall response rate (ORR) was 91.7% (22/24); the median progression-free survival (PFS) time was 15 months (95% CI 6.6-23.4 months); 6 CR patients were negative for minimal residual disease (MRD). The common adverse reactions were hematological adverse reactions, peripheral neuropathy, fatigue, gastrointestinal reactions, and infections. The incidence rate of grade 3-4 adverse reactions was 25.0% (6/24). In the relapsed/refractory group, the best efficacy was VGPR in 1 case, PR in 3 cases, and MR in 1 case, all patients withdrew from the IRd regimen therapy due to PD after transient remission or poor effect; in the conversion group, the best efficacy was CR in 8 cases, VGPR in 5 cases, PR in 5 cases, and PD in 1 case, 57.9% (11/19) patients maintained their original best response, and 36.8% (7/19) patients improved their best response to CR; the difference in median PFS time between the two groups was statistically significant (7 months vs. not reached, P = 0.018). Conclusions:The IRd regimen is safe and effective for MM patients, especially for the conversion patients after effective bortezomib induction therapy. Although patients with relapsed/refractory MM who have previously used multi-line therapy respond to IRd regimen, the duration of remission is limited.
8.Treatment progress of splenic marginal zone lymphoma
Journal of Leukemia & Lymphoma 2020;29(5):313-316
Splenic marginal zone lymphoma (SMZL) is a rare indolent B-cell lymphoma. Due to its rarity and the lack of large-scale prospective randomized trials of SMZL, the treatment of SMZL is mainly based on therapy regimens of other indolent lymphomas and expert consensus. Asymptomatic patients can wait and watch, while the traditional treatments of symptomatic patients include splenectomy and chemotherapy alone. Rituxmab monotherapy has become the new first-line option and been widely used because of its good efficacy over the last decades. With the further understanding of molecular etiology of various lymphomas, some novel target agents are under clinical trials in low-grade lymphoma including small amount of SMZL patients. This review mainly discusses the treatment progress of SMZL.
