Objective To evaluate the impact of chemotherapy compliance on the therapeutic efficacy of induction chemotherapy plus concurrent chemoradiotherapy versus induction chemotherapy plus radiotherapy alone for patients with locally advanced nasopharyngeal carcinoma (NPC). Methods Based on intention to treat analysis (ITT) for 400 patients, 314 patients were analyzed by per protocol (PP) analysis. The patients were divided into induction chemotherapy plus concurrent chemoradiotherapy group (IC/CCRT, 127 patients) or induction chemotherapy plus radiotherapy group (IC/RT, 187 patients). The patients who completed 2 cycles of induction chemotherapy and at least 2 cycles of concurrent chemotherapy in the IC/CCRT group and the patients who completed 2 cycles of induction chemotherapy in the IC/RT group were analyzed. Radiotherapy was given by two-dimensional technique with γ-ray, X-ray and electron beams. The chemotherapy regimen was FUDR plus carboplatin for induction chemotherapy and carboplatin alone for concurrent chemotherapy. Results The follow-up rate was 96.2%. 295 patients were followed to at 3 years. Based on PP analysis, Grade 3/4 toxicity was found in 23.6% of the patients in IC/CCRT group and 13.4% in the IC/RT group (χ~2 =5,50,P=0.019). No grade 4 toxicity was found in the IC/RT group. The median follow-up time was 3.9 years, and no significant difference was found between the two groups in 3-year overall survival (78.1% : 84.6% ;χ~2 = 0. 61, P =0. 435), disease-free survival (74.3 % : 70.1% ;χ~2= 0. 12, P= 0.731), Iocoregional relapse-free survival (89.7% : 89.5% ; χ~2= 0. 10, P= 0.748), or distant metastasis-free survival (78.9%:76.5% ;χ~2=0.05,P=0.825). Conclusions With more severe toxicities, the IC/CCRT regimen does not improve the overall survival in locally advanced NPC patients compared with the IC/RT regimen.

OBJECTIVETo study the effect of substrate stiffness on proliferation, migration of fibroblast and integrin β(1) expression in fibroblast.

METHODSFibroblasts were inoculated on silicon substrate with stiffness of (16.2 ± 0.5), (19.8 ± 1.1), and (200.1 ± 2.6) kPa. After being cultured for 5 days or 6 days, cells were counted and cell proliferative activities (recorded as absorbance value) were assessed with methyl thiazolyl blue (MTT). After being cultured for 3 days, cell cycle was detected and proliferation index (PI) was calculated. The cell scratch test was used for determination of cell migration rate on post scratch day (PSD) 0 (the day of scratch), 1, 2, and 3. After being cultured for 2 days, the expression of integrin β(1) was determined by flow cytometry with fluorescence. Data were processed with one-way analysis of variance.

RESULTS(1) The proliferative speed and proliferative activity of fibroblasts were all increased along with the increase in substrate stiffness. PI of fibroblasts inoculated on silicon substrate with stiffness of (16.2 ± 0.5), (19.8 ± 1.1), and (200.1 ± 2.6) kPa was respectively 24.8%, 27.4%, 32.4%. On PSD 2, migration rate of fibroblasts inoculated on silicon substrate with stiffness of (19.8 ± 1.1) and (200.1 ± 2.6) kPa was respectively (91.4 ± 5.1)%, (100.0 ± 1.3)%, which were higher than that of fibroblasts inoculated on silicon substrate with stiffness of (16.2 ± 0.5) kPa [(55.8 ± 6.8)%, with F value respectively 3.5, 4.0, P values all below 0.01]. (3) The expression rate of integrin β(1) in fibroblasts inoculated on silicon substrate with stiffness of (16.2 ± 0.5) kPa was the lowest (43.22%), and that in fibroblast inoculated on silicon substrate with stiffness of (200.1 ± 2.6) kPa was the highest (81.26%).

CONCLUSIONSSubstrate stiffness may have a great effect on proliferation and migration of fibroblast during the process of wound healing and scar formation, which can be related to regulation of integrin β(1) expression.

OBJECTIVETo analyze the embryo development potential after intracytoplasmic injection of sperm from azoospermia patients with different spermatogenic functions.

METHODSWe performed ICSI with sperm retrieved from azoospermia patients with different spermatogenic functions using percutaneous epididymal sperm aspiration (PESA) and testicular sperm aspiration (TESA). Then we recorded and analyzed the rates of normal fertilization, cleavages, excellent embryos and pregnancies.

RESULTSNo statistically significant differences were found between the PESA and TESA groups in the rates of normal fertilization ([74.9 +/- 19.6] vs [66.3 +/- 22.7]%, P > 0.05), cleavages ([96.7 +/- 8.6] vs [92.8 +/- 19.8]%, P > 0.05), excellent embryos ([43.5 +/- 26.2] vs [35.0 +/- 29.4]%, P > 0.05) and pregnancies (44.0 vs 52.0%, P > 0.05). The normal fertilization rates in the patients with normal spermatogenesis, mild spermatogenic dysfunction (SD), moderate SD and severe SD were (77.8 +/- 18.4), (68.4 +/- 18.5), (73.5 +/- 19.8) and (51.4 +/- 27.9)%, respectively, with significant difference between the normal spermatogenesis and mild SD groups (P < 0.05) as well as between the severe SD and the other groups (P < 0.05); the cleavage rates were (96.7 +/- 9.2), (96.5 +/- 15.0), (93.9 +/- 12.1) and (93.7 +/- 11.1)%, respectively, with no significant difference among the four groups; the excellent embryo rates were (47.1 +/- 25.8), (40.3 +/- 27.6), (36.2 +/- 23.1) and (15.0 +/- 24.6)%, respectively, with significant difference between the severe SD and the other groups; the pregnancy rates were 54.8, 50.0, 13.6 and 10.0%, respectively, with significant differences among the four groups (P < 0.001).

CONCLUSIONICSI by PESA or TESA is an effective approach to azoospermia. There are no significant differences between PESA and TESA in the rates of normal fertilization, cleavages, excellent embryos and pregnancies. The severity of spermatogenic dysfunction affects fertilization and initial development of embryos, which were shown in the rates of normal fertilization, excellent embryos and pregnancies but not that of cleavages.
