OBJECTIVETo explore the application value of morphology assessment of sperm from fresh semen in routine in vitro fertilization (IVF).
METHODSWe analyzed the morphology of the sperm from fresh or optimized semen samples and, based on the sperm morphology of the raw semen, allocated 908 IVF cycles due to the pure tubal factor to different groups: morphologically normal sperm (MNS) ≤ 4%, > 4% - ≤ 15%, and > 15% in Trial 1 and MNS ≤ 1%, > 1% - ≤ 2%, > 2% - ≤ 3%, and > 3%-- ≤ 4% in Trial 2. We compared the rates of fertilization, cleavage, high-quality embryo, -blastocyst formation, and pregnancy among different groups.
RESULTSThe total fertilization rate was significantly lower in the MNS ≤ 4% than in the MNS > 4% - ≤ 15% and >15% groups (74.40% vs 78.61% and 80.03%, P < 0.01). Compared with the MNS ≤ 1%, > 1% - ≤ 2%, and > 2% - ≤ 3% groups, the MNS > 3% - ≤ 4% group showed remarkably increased rates of 2PN normal fertilization (77.23%, 78.97% and 78.99% vs 85.47%, P < 0.01), cleavage (95.71%, 96.01% and 97.27% vs 98.73%, P < 0.05), and blastocyst formation (53.85%, 49.01% and 49.55% vs 63.41%, P < 0.01). No statistically significant differences were observed in the rates of clinical pregnancy, implantation, early abortion, live birth, or malformation at birth among different groups (P > 0.05).
CONCLUSIONMNS ≤ 4% affected the total rate of fertilization while MNS ≤ 3% reduced the rate of normal fertilization in IVF. However, even MNS ≤ 1% did not result in fertilization disorder or failure. Therefore, teratozoospermia alone was not an indicator of ICSI and sperm mor- phology assessment had no obvious value for predicting the rates of embryo quality, clinical pregnancy, and live birth in IVF.

Leaf senescence is often caused by water deficit and the chimeric gene P(SAG12)-IPT is an auto-regulated gene delaying leaf senescence. Using in vitro leaf discs culture system, the changes of contents of chlorophylls, carotenoids, soluble protein and thiobarbituric acid reactive substance (TBARS) and antioxidant enzymes activities were investigated during leaf senescence of P(SAGl2)-IPT modified gerbera induced by osmotic stress compared with the control plant (wild type). Leaf discs were incubated in 20%, 40% (w/v) polyethylene glycol (PEG) 6000 nutrient solution for 20 h under continuous light [130 micromol/(m(2) x s)]. The results showed that the contents of chlorophylls, carotenoids and soluble protein were decreased by osmotic stress with the decrease being more pronounced at 40% PEG, but that, at the same PEG concentration the decrease in the transgenic plants was significantly lower than that in the control plant. The activities of superoxide dismutase (SOD), catalases (CAT), ascorbate peroxidase (APX), guaiacol peroxidase (GPX) and dehydroascorbate reductase (DHAR) were stimulated by PEG treatment. However, the increases were higher in P(SAG12)-IPT transgenic plants than in the control plants, particularly at 40% PEG treatment. Lipid peroxidation (TBARS content) was increased by PEG treatment with the increase being much lower in transgenic plant than in the control plant. It could be concluded that the increases in the activities of antioxidant enzymes including SOD, CAT, APX, GPX and DHAR were responsible for the delay of leaf senescence induced by osmotic stress.

OBJECTIVETo investigate whether hyperthermia can enhance the killing effect of 5- fluorocytosine (5- FC) on human colorectal carcinoma cell lines SW480 transfected with carcinoembryonic antigen (CEA) tissue- specific cytosine deaminase (CD) gene in vitro,and study its mechanism.
METHODSHuman colorectal carcinoma cell lines SW480 transfected with G1CEACDNa were cultured. The proliferated colonies were treated with the combined therapy of 5-FC and hyperthermia at a temperature of 43 degrees C for 30 min. After eight days, MTT was used to calculate the cellular survival rate,to analyze the killing effect of 5-FC combined with hyperthermia on SW480 cells transfected with CD gene. Flow cytometry was performed to analyze the cellular cycle and transmission electron microscope was used to observe the morphologic changes of SW480 cells after thermochemotherapy.
RESULTSHyperthermia combined with 5-FC had an enhanced killing effect on SW480-CEACD cells than 5-FC alone (P< 0.05, t =2.403, n=9). Flow cytometry revealed that the proportion of S stage cell increased in the group treated with hyperthermia and 5- FC (P< 0.001, t =7.158, n=6). Transmission electron microscope showed apoptosis after thermo- chemotherapy.
CONCLUSIONSHyperthermia can improve the anti- tumor effect of 5- FC on human colorectal carcinoma cell lines SW480 transfected with CD gene, and the cells were blocked at S stage of cellular cycle and apoptosis was induced following thermochemotherapy.

OBJECTIVETo study a new implant material (carbonated hydroxyapatite, CHA) united pedicle screw to cure spine fracture.
METHODSThirty-two cases of spine compressed fracture were used with pedicle screw fixator and vertebroplasty. Before operation, patients' vertebral body were compressed (46 + 21)% (20% approximately 70%) on average. In operation, broken vertebral body was reposition through pedicle screw technique, then used self-made syringe to inject CHA into anterior and central column of broken vertebral body through pedicle. And all of patients were not given any bone-graft.
RESULTSIn 6 - 26 months followed-up, no immunologic rejection was found about hydroxyapatite, and no any broken of the screws and shafts was found, no loosing and other complications either. All the patients could move in 3 - 5 days after operation. The height of the broken vertebral body were reduced 97% compared with pre-operation. And CHA in vertebral body was degraded gradually, and at the same time it was replace by new bone in vertebral body. After operation, VAS score was 61 +/- 32, and there was significant difference compared with pre-operation.
CONCLUSIONSThe pedicle screw fixation united vertebroplasty is an efficient way to prevent the failure of the treatment of spine fracture.

Objective To study the rate of mother-to-child transmission (MTCT) on HIV-1. Methods All local residents from 8 townships in a region were screened for mothers who had a history of only one blood transfusion and 63 were found HIV-1 positive. A further study on these HIV-1 positive mothers and their children was conducted with the emphasis on the date of receiving blood transfusion, date and type of nationality, history regarding breastfeeding and so on. Sera specimens from 84 children born from 63 HIV-1 positive mothers were screened, using ELISA for HIV-1 antibody, and positive specimens were confirmed by Western-blot. Results The rate of MTCT was 32.1% (27/84) for children with all risk factors related to MTCT. Another 36.8% (7/19) were related to factors on intrauterine, intrapartum and breastfeeding, 35.7% (5/14) to intrapartum and breastfeeding factors, 14.3% (2/14) to intrauterine and intrapartum factors, 37.9% (11/29) to breastfeeding factor alone. By group combination analysis, the MTCT rate was 36.9% (24/65) with breastfeeding, 11.8% (2/17) with artificial feeding, and the former was significantly higher than the latter. Conclusion HIV-1 MTCT rate among mothers caused by a single blood transfusion varied with different risk factors. Breastfeeding played an important role in MTCT, appeared in our study.

OBJECTIVETo evaluate the effectiveness and safety of the combination chemotherapy of capecitabine (X) with fractionated administration of cisplatin (C) in Chinese patients with advanced gastric cancer (AGC).
METHODS141 patients with AGC were enrolled between July 2002 and August 2004. All patients had measurable tumor according to the criteria of RECIST, Karnofsky performance status > or = 60, adequate bone marrow, renal and hepatic functions. Prior radiotherapy or adjuvant chemotherapy was not permitted. Patients received oral administration of capecitabine at a dose of 1000 mg/m(2) twice a day on D1-D14, and intravenous infusion of fractionated cisplatin at a dose of 20 mg/m(2)/day on D1-D5. The regimen was repeated every 3 weeks, totally for 6 cycles.
RESULTSOf the 141 evaluable patients, there were 104 men and 37 women, with a median age of 54 years (range, 23 - 80 years). Metastases before chemotherapy were detected in lymph nodes (46.8%), liver (40.4%), lung (5.7%) and other area (10.6%). The median treatment duration was 6 cycles (range, 3 - 6 cycles). The objective response rate (RR) was 36.2% (51/141). The median follow-up period was 17.5 months. The median time to progress (TTP) was 9.0 months, and the median overall survival (OS) was 12.0 months. The most common treatment-related adverse events (grade 3/4) were: hand-foot syndrome (HFS) (2.1%), leucopenia (0.7%), abnormal alanine transaminase elevation (2.8%). There was no treatment-related death.
CONCLUSIONCapecitabine combined with fractionated cisplatin is highly effective and well tolerated as a first-line treatment for advanced gastric cancer, with comparable results to 5-Fu plus cisplatin combination therapy.
