OBJECTIVETo study the efficacy of stenting followed by laparoscopic surgery in the treatment of obstructing left-sided colon cancer.

METHODSForty-nine patients with obstructing left-sided colon cancer were prospectively randomized into two groups. Twenty patients received emergent open surgery, while 15 underwent laparoscopic surgery 3 days after placement of the self-expanding metal stent (SEMS) and 14 of them received laparoscopic surgery 10 days after placement of SEMS. Outcomes evaluated included 1-stage operation rate, conversion rate, operative time, length of hospital stay, blood loss, postoperative pain score and use of analgesics, rates of permanent stoma, and postoperative complications.

RESULTSCompared with emergent open surgery, patients undergoing laparoscopic surgery had significantly less blood loss(P=0.000), lower permanent stoma rate (P=0.024), less pain(P=0.000), and lower incidence of postoperative complications. Laparoscopic surgery was associated with a significantly higher rate of 1-stage operation(P=0.004). Compared with patients undergoing laparoscopic surgery 3 days after SEMS placement, patients who underwent laparoscopic surgery 10 days after SEMS placement had a significantly higher 1-stage operation rate(P=0.001) and a lower conversion rate(P=0.046).

CONCLUSIONSSelf-expanding metal stenting is a safe and effective bridge to laparoscopic surgery in patients with obstructing left-sided colon cancer. Laparoscopic surgery 10 days after SEMS placement may be more appropriate.

OBJECTIVETo analyze the outcome and prognosis of autologous hematopoietic stem cell transplantation (AHSCT) combined with high dose radiotherapy/chemotherapy in 22 patients with nasal NK/T cell lymphoma.

METHODSFrom July 1992 to December 2005, 22 patients with nasal NK/T cell lymphoma were diagnosed pathologically. Immunophenotyping was performed in 13 cases. The patients were classified by Ann Arbor staging system and international prognosis index (IPI). The patients received cycles of chemotherapy every other two weeks or combined with radiotherapy for remission induction, followed high dose radiotherapy/chemotherapy, combined with autologous peripheral blood stem cell transplantation (APBSCT), or autologous bone-marrow transplantation (ABMT). Patients were given complementary radiotherapy after transplantation if they did not have it before. Twelve patients of IPI 3 -4 received consolidation chemotherapy, and one of them received the second transplantation.

RESULTSThe median follow-up duration was 64 (12 - 168) months. The 5 and 8-year overall survivals (OS) were 79.3% and 64.1%, and disease free survivals (DFS) were 36.4% and 27.3%, respectively. The 5-year OS were as follows: for stage I - II and III - IV disease were 90.0% and 70.0% (P = 0. 041); for patients without and with B symptom were 100.0% and 70.7% (P = 0.045); and for IPI 1 - 2 and 3 - 4 were 100.0% and 60.0% (P = 0.035), respectively. Multivariate analysis by COX regression revealed that disease stage, B symptom and IPI were independent prognostic factors.

CONCLUSIONAHSCT combined with high dose radiotherapy/chemotherapy is an effective treatment for patients with poor prognosis nasal NK/T cell lymphoma.

OBJECTIVETo explore the correlation of males'age with sperm apoptosis, sperm DNA integrity and other seminal parameters.

METHODSWe collected 104 semen samples and divided them into three groups according to the males' age: <35 yr (n = 43), 35 -39 yr (n = 31), and > or = 40 yr (n = 30). Based on the WHO Laboratory Manual (4th ed), we detected the seminal parameters, calculated the percentage of apoptotic sperm by flow cytometry (FCM), determined sperm DNA integrity by Acridine orange staining, and compared the results among the three groups.

RESULTSThere were no statistically significant differences among the < 35 yr, 35 -39 yr and > or = 40 yr groups in semen volume ([2.87 +/- 0.89] ml vs [2.98 +/- 1.09] ml vs [2.65 +/- 0.95] ml), sperm concentration ([60.40 +/- 25.43] x 10(6)/ml vs [69.74 +/- 28.33] x 10(6)/ml vs [55.97 +/- 27.22] x 10(6)/ml) (P>0.05). The percentage of progressively motile sperm was significantly lower in the > or = 40 yr ([39.00 +/- 8.35 %) than in the <35 and 35 -39 yr groups ([48.73 +/- 9.89]% and [45.65 +/- 10.55]%) (P<.0.1), and so was the percentage of morphologically normal sperm in the > or = 40 yr than in the < 35 yr group ([11.11 +/- 8.26]% vs [16.43 +/- 8.75 ]%, P<0.01). The percentage of apoptotic sperm was markedly higher in the > or = 40 yr than in the <35 yr group ([11.82 +/- 5.77]% vs [7.04 +/- 3.50]%, P<0.01), while the sperm DNA integrity significantly reduced in the > or = 40 yr group ([75.52 +/- 10.60]%) as compared with the <35 yr ([86.55 +/- 5.60])% and 35 -39 yr group ( [81.39 +/- 8.94]%) (P<0.01). The males' age was correlated positively with the rate of sperm apoptosis (P<0.01), and negatively with sperm DNA integrity and the percentage of progressively motile sperm (P<0.01).

CONCLUSIONThe advance in males' age increases sperm apoptosis and reduces sperm progressive motility, normal morphology and DNA integrity.

OBJECTIVETo study the influence of male age on the outcome of conventional IVF-ET.

METHODSBased on male age, 170 couples undergoing conventional IVF-ET were divided into three groups: <35 yr (n = 60), 35 -39 yr (n = 77) and > or = 40 yr (n = 33). We observed the rates of fertilization, cleavage, good quality embryo, implantation, clinical pregnancy and abortion in different groups.

RESULTSThere were no significant differences among the three groups in semen volume ([3.10 +/- 1.22] ml vs [2.84 +/- 1.05] ml vs [2.80 +/- 0.79] ml), sperm concentration ([54.23 +/- 26.07] x 10(6)/ml vs [60.27 +/- 24.80] x 10(6)/ml vs [60.21 +/- 27.42] x 10(6)/ml) and sperm viability ([53.93 +/- 13.25]% vs [56.10 +/- 16.58]% vs [51.82 +/- 15.45]%) (P>0.05). The men of the > or = 40 yr group showed a significantly lower percentage of grade a + b sperm ([40.97 +/- 11.91]%) than those of the <35 and 35 - 39 yr groups ([48.47 +/- 11.78]% and [46.84 +/- 13.51]%) (P<0.05), and morphologically normal sperm ([11.76 +/- 5.97]%) than those of the <35 yr group ([15.25 +/- 6.94]% (P<0.05). The rates of fertilization, cleavage, good quality embryo, implantation, clinical pregnancy were 81.52%, 82.61%, 52.33%, 18.06% and 33.33% in the > or = 40 yr group, with no significant differences from those of the <35 yr group (83.18%, 82.68%, 56.99%, 22.40% and 40.00%) and the 35 - 39 yr group (78.78%, 80.66%, 55.01%, 21.74% and 38.96%) (P>0.05), while the abortion rate was markedly increased in the > or = 40 yr group as compared with the <35 yr group (36.36% vs 8.33%, P>0.05).

CONCLUSIONIncreasing male age is related with decreasing percentages of progressively motile sperm and morphologically normal sperm, but not obviously with the rates of fertilization, good quality embryo, implantation, pregnancy and abortion.
