Objective To evaluate the therapeutic effects of needling revision with mitomycin C(MMC) subconjuctival injection on early failed filtering blebs after trabeculectomy for glaucoma. Methods Needling revision with MMC 0.2 mL(0.04 mg) subconjuctival injection was performed on 86 eyes of 76 patients with failed filtering blebs 2 to 6 weeks after trabeculectomy for glaucoma.An average of 1.88 times of treatment was performed.The intraocular pressure(IOP),blebs and side effects were observed,and follow-up was conducted for 6 months. Results Two to six weeks after trabeculectomy,there were 50 eyes with thickened and focalized blebs,32 eyes with encapsulated blebs and 4 eyes with no bleb.Six months after needling revision with MMC subconjuctival injection,blebs of 61 eyes turned into functional ones.The blebs were thinned and multicysted in 24 eyes,diffused and elevated in 37 eyes,thickened and focalized in 6 eyes,encapsulated in 13 eyes and disappeared in 6 eyes.Three months after treatment,the mean IOP was(15.2?6.1) mmHg,and there were 57 eyes with IOP

Objective To investigate symptom characteristics and their their prevalence in terminally ill patients with ovarian carcinoma.Methods A retrospective study was carried out based on clinical data of 98 terminally ill patients with ovarian carcinoma who died in our hospital during January 1995 to December 2004.Fifteen most common symptoms were analyzed with a focus on the followings:symptom incidence,survival time after symptom occurrence,regularity of symptom cluster,and common causes of death.Fifteen symptoms were:pain,cachexia,pleural effusion and ascites,dyspnea,fever,intestinal obstruction,renal failure,bone marrow depression,lung infection,hemorrhage,deep venous thrombosis (DVT),intestinal or pancreatic fistula,mycotic infection,jaundice and emergency conditions.Results (1)The most prevalent symptom was pleural effusion and ascites(63%),followed by pain(60%), cachexia(59%),dyspnea(52%)and intestinal obstruction(49 %).(2)The symptom which lasted longest survival time was mycotic infection(77 days),followed by intestinal or pancreatic fistula(75 days), intestinal obstruction(67 days),pain(60 days)and eachexia(60 days).Symptoms such as bone marrow depression,renal failure,dyspnea and emergency conditions were comparatively critical associated with shorter survival times(14,13,12,7 days,respectively).(3)Terminal symptoms occurred typically in clusters,with 4.9?1.5 symptoms per case.Of 98 cases,84 cases(86%)had 4 or more symptoms,with the median survival time of 63 days from the last day of anti-cancer therapy,and a slow death process.The remaining 14 cases(14%)with 3 or fewer symptoms survived only 25 days,of which 10 cases(71%)died of emergency diseases.The survival time for two groups was significantly different(P

Objective To evaluate the development of immature oocytes after freezing-thawing by conventional cryopreservation method for mature oocytes.Methods Immature oocytes were collected from stimulated ovaries of intracytoplasmic sperm injection(ICSI)cycles.Immature oocytes were in vitro matured directly or after slow freezing-fast thawing and immunostained for tubulin and chromatin and at last visualized by confocal microscopy.Results No statistical difference was found in maturity rate between freezing groups and the controls.There was a statistically significant increase in abnormalities of chromosome(23.7% vs. 50%)and spindle(28.9% vs.53.9%)in the GV freezing group compared with the GV control(P

Objective To compare the effects of vitrification with slow-freezing on the developmental ability of day 3 cleavage stage embryos.Methods Patients who had no less than 4 high quality embryos were included in this study.These embryos were cryopreserved using the methods of vitrification or slow-freezing.In the eryopreserved embryo transfer cycles,the embryos which were cryopreserved using one of the methods were chosen randomly.The developmental ability of embryos was compared between these two groups.Results A total of 80 patients were included in this study with 160 embryos.In the group of slow-freezing,73(91%)embryos were survived and achieved 15(38%)clinical pregnancies.Among these,3 were twins and the implantation rate was 25%(18/73).In the group of vitrification,71(89%)embryos were survived and achieved 19(48%)clinical pregnancies.Among these, 9 were twins and the implantation rate was 39%(28/71),which was significantly higher than the slow- freezing group(P

OBJECTIVETo investigate the pathogenesis of globozoospermia, fertilization ability of round-headed sperm, and the application value of assisted oocyte activation in intracytoplasmic sperm injection (ICSI) for the wives of glohozoospermia men.

METHODSWe collected oocytes from the wives of 2 globozoospermia patients and randomly divided them into two groups after ICSI to receive calcium ionophore A23187-activation and conventional treatment, respectively. We reviewed the relevant literature published at home and abroad, and discussed the etiology of globozoospermia, fertilization ability of round-headed sperm, and treatment options for this disease.

RESULTSQuality embryos were obtained in the A23187-activation group while no fertilized oocytes, oocyte cleavage, quality embryos, or blastular formation were found in the conventional treatment group. Both women achieved pregnancy and gave birth to healthy neonates after transfer of the quality embryos from the A23187-activation group.

CONCLUSIONCalcium ionophore A23187 can be applied to ICSI for the wives of globozoospermia men and bring about desirable clinical outcomes. Meanwhile, attention should be paid to its safety.

BACKGROUNDPulmonary embolism, a potentially fatal event, occurs more frequently in cancer patients than in the general population. To offer an accurate diagnosis and effective treatment to such patients in China, we analyzed the incidence rate and clinical features of pulmonary embolism in patients with solid tumor hospitalized in the Peking Union Medical College (PUMC) Hospital.

METHODSA retrospective analysis was made of the hospitalized patients with solid malignancies complicated with pulmonary embolism who had been admitted into the PUMC Hospital from January 2002 to December 2008.

RESULTSThe incidence of pulmonary embolism in hospitalized patients with solid malignancies was 0.27% (120/43 967). The median age at diagnosis was 57.5 years. The male to female ratio was 1.0:1.4 (49:71). Patients with non-small-cell lung cancer (NSCLC) constituted the largest proportion of the 120 patients (37.5%), followed by patients with breast (9.2%), ovarian (8.3%), pancreatic (6.7%), and liver cancer (6.7%). Eighty patients (66.7%) had stage IV cancer. Bone was the most common site of distant metastasis (46.3%). D-dimer level was elevated in 90.9% of the 66 tested patients. The incidence of bleeding due to anti-coagulation therapy was 3.6%. Thirty-six (30.0%) of the 120 patients had concurrent deep venous thrombosis in the lower extremities. Seventeen patients developed acute pulmonary embolism within 2 weeks after surgery, 3 of whom died suddenly. Four patients presented with deep venous thrombosis and 1 with pulmonary embolism prior to the identification of malignancy.

CONCLUSIONSPatients with cancer of the lung, ovarian, breast, pancreas, and liver are more likely to be complicated with pulmonary embolism than those with other types of solid tumors. Patients with distant metastasis are at a higher risk of pulmonary embolism. Pulmonary embolism without concurrent deep venous thrombosis is more frequently observed than concurrence of both disorders in the clinical setting.

OBJECTIVETo evaluate the efficiency of density gradient and improved swim-up methods for motile sperm isolation from fresh semen samples in intracytoplasmic sperm injection and embryo transfer (ICSI-ET) program, thus guiding the clinical application.

METHODSThe fertilization rate, cleavage rate, high-quality embryo rate, clinical pregnancy rate, sperm abnormal rate and recovery rate of 42 cycles were studied prospectively. The cycles were divided into two groups with respect to the motile sperm isolation methods.

RESULTSNo obvious difference was found in the fertilization rate, cleavage rate, high-quality embryo rate and clinical pregnancy rate between the two methods. The abnormal sperm rate induced by the improved swim-up method was significantly higher than that of the density gradient method (P < 0.01). For severe oligozoospermia, the recovery rate of motile sperm with density gradient was higher than that of improved swim-up (P < 0.01).

CONCLUSIONIn the ICSI-ET, there is no obvious difference in clinical pregnancy outcome between the two methods. The method of improved swim-up can be used for all patients but those with severe oligozoospermia.

OBJECTIVETo investigate the sex chromosomes and the expression of insulin-like growth factor-II (IGF-II) on activated human unfertilized oocytes after intracytoplasmic sperm injection(ICSI) with calcium ionophore A23187 and puromycin.

METHODSAll 95 discarded oocyes that showed no evidence of fertilization at 16-18 h after in vitro maturation and intracytoplasmic sperm injection cycles (IVM-ICSI)/conventional ICSI were exposed to calcium ionophore A23187 (5 micromol/L) for 5 min and then were incubated with puromycin (10 microg/mL) for 4 h. After activation, the oocytes were cultured in vitro for 3-5 days. The sex chromosome analysis was performed by dual color fluorescence in situ hybridization. The expression of IGF-II on the activated embryos, normal embryos, and parthenotes was examined.

RESULTSThe combination of calcium ionophore A23187 with puromycin could activate the unfertilized oocytes 22 h after ICSI. The activated rate, cleavage rate, and quality of activated embryos of the IVM-ICSI group were similar to those of ICSI group, respectively. Sex chromosome analysis indicated that 8 male and 5 female embryos had been derived from two pronucleus and a second polar body. The expression of IGF-II on activated embryos and normal embryos was high and similar, which was much stronger than that of parthenotes.

CONCLUSIONThe combination of calcium ionophore A23187 with puromycin could effectively activate unfertilized oocytes 22 h after ICSI. Moreover, the unfertilized oocytes activated by calcium ionophore A23187 and puromycin had normal sex chromosomes and expression of IGF-II like the normal embryos. These suggest that oocyte activation may be considered as a remedial measure in the presence of total or nearly total fertilization failure in ICSI.
