OBJECTIVETo explore various factors affecting the clinical pregnancy outcomes of artificial insemination with donor sperm (AID).
METHODSWe retrospectively analyzed 15,744 cycles of AID in 6302 women and investigated the association of the clinical pregnancy outcomes of AID with the treatment protocols, the times of insemination per cycle, the age of the infertile women, the status of the oviduct, and the number of AID cycles.
RESULTSThe pregnancy rate of AID was higher in the chlomiphene-treated women than in those of the natural cycle group (P = 0.003) but showed no significant differences either between the chloramiphene and human menopause gonadotropin (HMG) or between the HMG and natural cycle groups (P > 0.05), and so was it in the women that had received AID twice per cycle before and after ovulation (26.3%) than in those that had undergone only once before (7.0%) or after ovulation (23.7%) (P < 0.05). However, the pregnancy rate was remarkably lower in the women aged 35-40 years (16.5%), especially in those over 40 years (1.2%), than in those under 35 years (26.0%) (P < 0.05). There was no significant difference in the success rate of AID between the women with oviductal adhesion and those without (27.4% vs. 28.1%, P > 0.05). The pregnancy rate of the first cycle of AID (27.6%) was markedly higher than those of the second (24.7%), third (23.9%), and fourth (23.1%) (P < 0.01), but with no significant differences among the latter three cycles (P > 0.05), while that of the fifth cycle (19.0%) was remarkably lower than those of the first four (P < 0.01).
CONCLUSIONThe age of the infertile women is an important factor affecting the success rate of AID. AID twice per cycle is better than once only. For those without oviductal factors, at least 4 cycles of AID are required before in vitro fertilization.

BACKGROUND:Studies have shown that umbilical cord blood stem cel transplantation promote the recovery of spinal cord injury, and electroacupuncture also can inhibit the proliferation of astrocytes to reduce damage to scar formation, suggesting that a combination of umbilical cord blood stem cel transplantation and electroacupuncture may play an important role in the treatment of acute spinal cord injuries. OBJECTIVE:To observe the influence of transplantation of human umbilical cord blood stem cels combined with electroacupuncture at theDu channel on expression of nerve growth factor and neurotrophin 3 in rats with spinal cord injuries. METHODS: Seventy-two female Sprague-Dawlay rats were randomly divided into control group, injury group, transplantation group and combined therapy group. In the control group, only an incision on the back was sutured;in the injury group, a piece of saline-infiltrated gelatin sponge, 1 mm×2 mm×2 mm, was placed into the transected spinal cord at T10 level; in the transplantation group and combined therapy group, a piece of gelatin sponged infiltrated in the suspension of human umbilical cord blood stem cels was placed into the transected spinal cord, respectively, and then, electroacupuncture stimulation at the Duchannel was performed in the combined therapy group at 1 hour after modeling. Specimens were taken at 7, 14, 28 days after modeling in each group, and then immunohistochemistry, western blot and real time-PCR methods were used to detect the expression of nerve growth factor and neurotrophin 3. RESULTS AND CONCLUSION:Compared with the transplantation group, the expression of nerve growth factor and neurotrophin 3 was lower in the injury group but higher in the combined therapy group at 7, 14, 28 days after modeling (P < 0.05). The results of western blot and real time-PCR were consistent with those of immunohistochemical detection. Findings show that human umbilical cord blood stem cel transplantation combined with electroacupuncture has a remarkable synergistic effect in the treatment of spinal cord injury that can significantly up-regulate the expression of nerve growth factor and neurotrophin 3, and contribute to injured spinal cord repair, regeneration and functional recovery after spinal cord injury.

Objective: To assess the effect of coronary collateral circulation (CCC) on myocardial viabilityin patients with chronic total occlusion of left anterior descending (LAD) artery. Methods: A total of 101 consecutive patients with confirmed diagnosis of total LAD occlusion in our hospital were enrolled. Rest 99mTc-MIBISPECT myocardial perfusion and 18F-FDG PET were performed, in addition all patients received coronary angiography (CAG) at 3 months front and back. Both images were reconstructed in the same machine and QPS software was used to obtain the summed rest score (SRS), abnormal resting total perfusion defect (TPD), viable and non-viable myocardium, LVEDV, LVESV and LVEF in relevant patients. Based on CAG result, the patients were divided into 2 groups: CCC group, n=39 and No CCC group, n=62; according to existing old myocardial infarctionand location of LAD occlusion, the patients were further divided into 4 subgroups. The above parameters were compared among different groups. Results: There were 86 male and 15 female patients with the mean age at (59.92±11.43) years. Relevant parameters in CCC group and No CCC groupwere as in SRS: (21.23±9.68) vs (28.56±8.76), TPD: (30.03±13.69) %vs (40.37±12.50) %, viable myocardium: (21.77±13.12) % vs (13.66±9.23) %, non-viable myocardium (8.28±8.58) %vs (27.40±12.97) %, all P<0.05; in LVEDV: (109.82±30.01) ml vs (173.71±57.69) ml, LVESV: (62.82±22.39) ml vs (122.53±51.66) ml, LVEF: (43.85±8.46) % vs (31.03±8.30) %, all P<0.05. Conclusion: Our preliminary study found that CCC could maintain left ventricular rest perfusion, myocardial viability and protect cardiac function in patients with chronic total LAD occlusion.

27 rabbits were divided into normal group(n = 4),control group (n = 5), silybin group (n = 6), hyperbaric oxygen (HBO) group (n = 6), and HBO combined with silybin group (n = 6). Circulation of hindlimb was interrupted completely for 6 h and reperfused for 1 h. Malondialdehyde (MDA) and superoxide dismutase(SOD) in plasma from ischemic-reperfused injured limb were measured. Adenosine triphosphate (ATP) and creatine phosphate (CP) in samples taken from anterior tibial muscle were determined. Ultrastructural changes of injured muscle were observed. The results showed that HBO combined with silybin treatment had a favourable effect on ischemic and reperfused injured limb muscle with reduction of the lipid peroxidated injury, increase of the SOD activity and the high energy phosphate compounds (ATP and CP), and a promoting recovery of injured muscle cells. HBO and silybin had a synergistic action. It suggests that HBO combined with silybin is an effective method for treatment of ischemic and reperfused injured limb.
