Chinese Journal of Minimally Invasive Surgery 2001;0(03):-
Objective To analyze the feasibility, safety, and technique of laparoscopic myomectomy in patients with large hysteromyoma. Methods A total of 82 hysteromyoma patients with the uterus larger than 14-week gestational size were treated by laparoscopic myomectomy. The outcome of the operation were compared with that in 182 hysteromyoma cases with the uterus smaller than 14-week gestational size. Results In the 82 patients with the uterus larger than 14-week gestational size, 77 were treated successfully by laparoscopy, in which pneumoperitoneum was used in 68 cases and gasless laparoscopy in the other 9. One of the cases converted to open surgery, and small abdominal incision was made in 4 patients. Compared with the patients with the uterus smaller than 14-week gestational size, the 77 patients who had been successfully by laparoscopy had longer operation time [(157.6?89.7) min vs (35.3?26.2) min, t=16.926, P=0.000] and more blood loss [(218.0?108.2)ml vs (108.5?67.5)ml,t=9.904,P=0.000]. Conclusions Myomectomy can be performed under a laparoscope for patients with the uterus larger than 14-week gestational size. Highly skilled technique is important for the surgery.!Gasless laparoscopy is applicable to myomectomy for patients with the uterus smaller than 16-week gestational size.

Objective To study the effect of aspirin on cell proliferation of human gastric cancer cell line SGC-7901 and the probab le mechanism involved. Methods Using MTT method, flow cytometr y (FCM),~~~3 H-TdR incorporation a nd electron microscopy, the effect of aspirin on the SGC-7901 of proliferation and related mechanism were studied. Results Results showed that th e growth of SGC -7901 was inhibited by aspirin. The inhibitory rates for growth of SGC-7901 we re positively correlated with the concentration and duration of aspirin in the m edia. ASA could inhibit DNA syntheses. Sub-G_1 pe ak was detected by FCM, and the rate of apoptosis was between 7.8% and (34.4)% . The cell ratios o f S and G_2/M increased, whereas the cell ratio of G_0/G_1 phase decreased (after) treatment and was in a dose-dependent manner. The SGC-7901 cell line exhibited some mor p hologic features of apoptosis, including cell shrinkage, nuclear condensation, D NA fragmentation, and formation of apoptotic bodies under electron microscopy. Conclusions Aspirin inhibited the growth of human gastric cancer ce ll line SGC-7901. The effects of aspirin on the phase of cell cycle and inducing apoptosis may be partially explained as the cytotoxic effects of aspirin.

Objective The aims of this study were to investigate the expression of microRNA-30a(miR-30a)in human bladder cancer cell lines and their effects on the proliferation,apoptosis and migration of human bladder cancer cells.Methods The expression levels of miR-30a in bladder cancer cell lines(5637 and T24)and bladder epithelial immortalized cells(SV-HUC-1)were detected by real-time quantitative PCR(qRT-PCR).The expression of miR-30a was up-regulated or down-regulated by T24 cells transfected with miR-30a mimic or 5637 cells transfected with miR-30a inhibitors and controls using NC mimic or NC inhibitor.The effects of miR-30a expression on the proliferation,apoptosis and invasion of bladder cancer cells were investigated by flow cytometry,MTT and Transwell assays.Results The expression level of miR-30a in two bladder cancer T24 and 5637 cell lines was significantly lower than that in normal bladder SV-HUC-1 cell line(P<0.05),and the expression level of miR-30a was lower in the high degree of malignancy in bladder cancer T24 cells than that in malignant degree of relatively low 5637 cells.After 72h transfection,the values of optical density(OD)in the miR-30a mimic group(0.83±0.09)was significantly lower than that in NC mimic group(1.21±0.12)in T24 cells(P<0.01).The OD values of miR-30a inhibitor group(1.28±0.14)was significantly lower than that in the NC inhibitor group(1.09±0.14)in 5637 cells(P<0.01).The apoptotic rate of miR-30a mimic group in T24 cells(21.27±2.42)% was significantly higher than that in the NC mimic group(10.61±1.29)%(P<0.01).The apoptotic rate of the miR-30a inhibitor group in 5637 cells(6.78±2.57)% was significantly lower than that in the NC mimic group(13.42±1.40)%(P<0.01).The number of transmembrane cells in miR-30a mimic group in T24 cells(183.57±16.61)was significantly lower than that in NC mimic group(465.80±9.20)(P<0.01).The number of transmembrane cells in the miR-30a inhibitor group in 5637 cells(581.25±11.02)was significantly lower than that in NC mimic group(397.13±7.57)(P<0.01).Conclusion Up-regulation of miR-30a can inhibit the proliferation of bladder cancer cells,promote cell apoptosis and reduce the ability of migration and invasion in bladder cancer cells.The low expression of miR-30a in bladder cancer cells may be related to the development and metastasis in bladder cancer.

Usage of reverse genetic techniques in the research area of the fundamental etiology of foot-and-mouth disease virus (FMDV), has resolved the issue about the function of viral gene of FMDV on genomic integer level. At present, a further recognition and apprehension for the molecular etiology of FMDV based on the development in reverse genetics was made. Combined with the research work in our labs, we reviewed international advances about the molecular pathogenic mechanism, the relationship be-tween virulence and variation in the genomes, influencing factors for the viral replication, and the develop-ment of new-type gene vaccine of FMD in this article, and propose the potential research aspects in reverse genetics of FMDV in the future.

Objective To investigate whether mesenchymal stem cells can promote the recovery of acute renal tubular damage induced by mercuric chloride and to explore its possible mechanism.Methods Acute renal failure rat model was established by intraperitoneal injection of mercuric chloride.SD rats were randomly divided into three groups which were MSCs injection group, saline infusion group and normal control group.Seven days later,the changes of rat weight,survival,renal function and pathology were observed;PCNA,ED-1 and GFP were detected by immunohistochemistry; The expression of cytokines in kidney and the distribution of GFP plasmid-transfected MSCs in kidney were examined by RT-PCR.Results MSCs infusion ameliorated the decline of rat weight,survival, renal function,and pathological changes.PCNA and ED-1 positive cells in MSCs group were fewer than those in saline group.Expression of growth factors EGF,PDGF,HGF were obviously up- regulated and pre-inflammatory cytokines TNF-?was significantly reduced in MSCs-treated kidneys. GFP-labelled MSCs occurred occasionally in renal interstitium of MSCs-treated rats,but not in renal tubules.Conclusions Bone marrow mesenchymal stem cells can promote the recovery of acute renal tubular epithelial cells damage caused by mercuric chloride.The mechanism may partly depend on regulating the excretion of cytokines in renal microenvironment rather than completely depend on their differentiation to tubular cells.

Objective To assessed the expression of inducible costimulator(ICOS)on peripheral blood and joint fluid CD4,CDS,CD45RO T cells and B cells in rheumatoid arthritis(RA).Methods Expression of ICOS and ICOS/CD45RO on peripheral blood and joint fluid CD4~+CD8~+T cells and ICOS ligand(ICOSL)on CD19 B cells from RA patients and healthy volunteers were determind by three-color flow cytometry.Compar- ision with active and inactive RA,initial and relapsed RA had been done.Results Joint fluid CD4 and CD8 T cells expressing ICOS,ICOS/CD45RO were significantly increased than peripheral blood in RA patients and healthy subjects.Joint fluid B cells expressing ICOSL were significantly reduced than peripheral blood in RA patients.Meanwhile,peripheral blood B cells expressing ICOSL were significantly reduced in active RA than inactive RA patients.Conclusion Hyperexpression of ICOS and ICOS/CD45RO on joint fluid CD4 and CD8 T cells and lowexpression of ICOSL in B cells from RA patients,expecially in active RA may contribute to the local immunopathological roles and joint destructions in the pathogenesis of RA.
